FORWARD-LOOKING STATEMENTS
This report contains forward-looking statements that are based on management's beliefs, assumptions, current expectations, estimates and projections about the financial services industry, the economy and Chemical Financial Corporation (Corporation). Words such as "anticipates," "believes," "estimates," "expects," "forecasts," "intends," "is likely," "judgment," "opinion," "plans," "predicts," "probable," "projects," "should," "trend," "will," and variations of such words and similar expressions are intended to identify such forward-looking statements. Such statements are based upon current beliefs and expectations and involve substantial risks and uncertainties which could cause actual results to differ materially from those expressed or implied by such forward-looking statements. These statements include, among others, statements related to future levels of loan charge-offs, future levels of provisions for loan losses, real estate valuation, future levels of nonperforming assets, the rate of asset dispositions, future capital levels, future dividends, future growth and funding sources, future liquidity levels, future profitability levels, future deposit insurance premiums, the effects on earnings of future changes in interest rates, the future level of other revenue sources, future economic trends and conditions, future initiatives to expand the Corporation's market share, expected performance and cash flows from acquired loans, future effects of new or changed accounting standards, future opportunities for acquisitions, the impact of acquisition transactions on the Corporation's business, opportunities to increase top line revenues, the Corporation's ability to grow its core franchise, future cost savings and the Corporation's ability to maintain adequate liquidity and capital based on the requirements adopted by the Basel Committee on Banking Supervision and U.S. regulators. All statements referencing future time periods are forward-looking.
Management's determination of the provision and allowance for loan losses; the carrying value of acquired loans, goodwill and mortgage servicing rights; the fair value of investment securities (including whether any impairment on any investment security is temporary or other-than-temporary and the amount of any impairment); and management's assumptions concerning pension and other postretirement benefit plans involve judgments that are inherently forward-looking. There can be no assurance that future loan losses will be limited to the amounts estimated. All of the information concerning interest rate sensitivity is forward-looking. The future effect of changes in the financial and credit markets and the national and regional economies on the banking industry, generally, and on the Corporation, specifically, are also inherently uncertain. These statements are not guarantees of future performance and involve certain risks, uncertainties and assumptions ("risk factors") that are difficult to predict with regard to timing, extent, likelihood and degree of occurrence. Therefore, actual results and outcomes may materially differ from what may be expressed or forecasted in such forward-looking statements. The Corporation undertakes no obligation to update, amend or clarify forward-looking statements, whether as a result of new information, future events or otherwise.
This report also contains forward-looking statements regarding the Corporation's outlook or expectations with respect to the planned merger with Talmer Bancorp, Inc. (Talmer), the expected costs to be incurred and cost savings to be realized in connection with the transaction, the expected impact of the transaction on the Corporation's future financial performance and consequences of the integration of Talmer into the Corporation.
Risk factors relating both to the transaction and the integration of Talmer into the Corporation after closing include, without limitation:
•
Completion of the transaction is dependent on, among other things, receipt of regulatory approvals and receipt of the Corporation's and Talmer's shareholder approvals, the timing of which cannot be predicted with precision at this point and which may not be received at all.
•
The impact of the completion of the transaction on the Corporation's financial statements will be affected by the timing of the transaction.
•
The transaction may be more expensive to complete and the anticipated benefits, including anticipated cost savings and strategic gains, may be significantly harder or take longer to achieve than expected or may not be achieved in their entirety as a result of unexpected factors or events.
•
The integration of Talmer’s business and operations into the Corporation, which will include conversion of Talmer’s operating systems and procedures, may take longer than anticipated or be more costly than anticipated or have unanticipated adverse results relating to the Corporation's or Talmer’s existing businesses.
•
The Corporation’s ability to achieve anticipated results from the transaction is dependent on the state of the economic and financial markets going forward. Specifically, the Corporation may incur more credit losses than expected and customer attrition may be greater than expected.
In addition, risk factors include, but are not limited to, the risk factors described in Item 1A of this report. These and other factors are representative of the risk factors that may emerge and could cause a difference between an ultimate actual outcome and a preceding forward-looking statement.

Additional Information about the Transaction
The Corporation will file a registration statement on Form S-4 with the Securities and Exchange Commission (SEC) to register the securities that the Talmer shareholders will receive if the transaction is consummated. The registration statement will contain a prospectus for the Corporation and a joint proxy statement to be used by the Corporation and Talmer to solicit the required approvals of their respective shareholders of the merger and other relevant documents concerning the transaction. Chemical and Talmer may also file other documents with the SEC concerning the proposed merger.

PART I.
Item 1. Business.
General Business
Chemical Financial Corporation (Corporation), headquartered in Midland, Michigan, is a financial holding company registered under the Bank Holding Company Act of 1956 and incorporated in the State of Michigan. At December 31, 2015, the Corporation's consolidated total assets, loans, deposits and shareholders' equity were $9.19 billion, $7.27 billion, $7.46 billion and $1.02 billion, respectively, and the Corporation employed approximately 2,100 full-time equivalent employees. For more information about the Corporation's financial condition and results of operations, see the consolidated financial statements and related notes included in Part II, Item 8 of this report.
The Corporation was incorporated in August 1973. On June 30, 1974, the Corporation acquired Chemical Bank and Trust Company (CBT) pursuant to a reorganization in which the former shareholders of CBT became shareholders of the Corporation. CBT's name was changed to Chemical Bank on December 31, 2005. In addition to the acquisition of CBT, the Corporation has acquired 24 community banks and 36 other branch bank offices through December 31, 2015. The Corporation's most recent transactions include the acquisitions of Lake Michigan Financial Corporation (Lake Michigan) and Monarch Community Bancorp, Inc. (Monarch) during the second quarter of 2015 and the acquisition of Northwestern Bancorp, Inc. (Northwestern) during the fourth quarter of 2014. In addition, on January 25, 2016, the Corporation entered into an Agreement and Plan of Merger with Talmer Bancorp, Inc. (Talmer). Completion of the merger is subject to regulatory approval and the approval of the Corporation's and Talmer's shareholders, in addition to satisfaction of other customary closing conditions. These transactions are discussed in more detail under the subheading "Mergers, Acquisitions and Branch Closings" included in Management's Discussion and Analysis of Financial Condition and Results of Operations.
The Corporation's business is concentrated in a single industry segment - commercial banking. The Corporation conducts its commercial banking activity through a single commercial bank subsidiary, Chemical Bank. Chemical Bank offers a full range of traditional banking and fiduciary products and services. These include business and personal checking accounts, savings and individual retirement accounts, time deposit instruments, electronically accessed banking products, residential and commercial real estate financing, commercial lending, consumer financing, debit cards, safe deposit box services, money transfer services, automated teller machines, access to insurance and investment products, corporate and personal wealth management services and other banking services. Chemical Bank operated through an internal organizational structure of four regional banking units and 18 community banking units as of December 31, 2015. In addition, the Corporation owns, directly or indirectly, various non-bank operating and non-operating subsidiaries.
The principal markets for the Corporation's products and services are the communities in Michigan where Chemical Bank's branches are located and the areas surrounding these communities. As of December 31, 2015, the Corporation and Chemical Bank served these markets through 185 banking offices located in 47 counties in Michigan. In addition to the banking offices, Chemical Bank operated three loan production offices and over 200 automated teller machines, both on- and off-bank premises, as of December 31, 2015.
A summary of the composition of the Corporation's loan portfolio at December 31, 2015, 2014 and 2013 was as follows:

The Corporation's loan portfolio totaled $7.27 billion at December 31, 2015, compared to $5.69 billion and $4.65 billion at December 31, 2014 and 2013, respectively. The Corporation's loan portfolio increased $1.58 billion, or 28%, during 2015, with commercial loans increasing $551 million, or 41%, commercial real estate loans increasing $555 million, or 36%, real estate construction increasing $57 million, or 38%, residential mortgage loans increasing $319 million, or 29%, consumer installment

5

loans increasing $48 million, or 6%,home equity loans increasing $50 million, or 7%, and land development loans increasing $3 million, or 17%. The growth in loans during 2015 was attributable to $1.11 billion of loans acquired in the Lake Michigan and Monarch transactions and $476 million of organic loan growth. The Corporation's loan portfolio increased $1.04 billion, or 22%, during 2014, with the increase attributable to $475 million of loans acquired in the Northwestern transaction and $565 million of organic loan growth. The Corporation's organic loan growth during 2015 and 2014 was the result of a combination of improving economic conditions in Michigan and the Corporation increasing its loan market share in its lending markets. The Corporation's loan portfolio is not concentrated in any one industry.
The principal source of revenue for the Corporation is interest income and fees on loans, which accounted for 73%, 72% and 71% of total revenue in 2015, 2014 and 2013, respectively. The Corporation has no foreign loans, assets or activities. No material part of the business of the Corporation or Chemical Bank is dependent upon a single customer or very few customers. Interest income on investment securities, services charges and fees on deposit accounts and wealth management revenue are also significant sources of revenue. Interest income on investment securities accounted for 5% of total revenue in 2015 and 6% of total revenue in both 2014 and 2013. Services charges and fees on deposit accounts accounted for 7% of total revenue in 2015 and 8% of total revenue in both 2014 and 2013. Wealth management revenue accounted for 6% of total revenue in both 2015 and 2014 and 5% of total revenue in 2013.
The Corporation offers services through the Wealth Management department of Chemical Bank. These services include trust, investment management and custodial services; financial and estate planning; and retirement and employee benefit programs. The Wealth Management department earns revenue largely from fees based on the market value of those assets under management, which can fluctuate as the market fluctuates. The Wealth Management department had assets under custodial and management arrangements of $3.71 billion, $3.73 billion and $2.51 billion as of December 31, 2015, 2014 and 2013, respectively. The Wealth Management department also sells investment products (largely annuity products and mutual funds) through its Chemical Financial Advisors program. Customer assets within the Chemical Financial Advisors program were $873 million, $878 million and $737 million as of December 31, 2015, 2014 and 2013, respectively. The growth in assets under management by Chemical Bank's Wealth Management department and assets within the Chemical Financial Advisors program during 2014 was largely attributable to the Northwestern transaction.
The nature of the business of Chemical Bank is such that it holds title to numerous parcels of real property. These properties are primarily owned for branch offices. However, the Corporation and Chemical Bank may hold properties for other business purposes, as well as on a temporary basis for properties taken in, or in lieu of, foreclosure to satisfy loans in default. Under current state and federal laws, present and past owners of real property may be exposed to liability for the cost of clean up of contamination on or originating from those properties, even if they are wholly innocent of the actions that caused the contamination. These liabilities could exceed the value of the contaminated property and could be material to the financial condition of the Corporation.
Competition
The business of banking is highly competitive. The principal methods of competition for financial services are price (interest rates paid on deposits, interest rates charged on loans and fees charged for services) and service (convenience and quality of services rendered to customers). In addition to competition from other commercial banks, banks face significant competition from non-bank financial institutions, including savings and loan associations, credit unions, finance companies, insurance companies and investment firms. Credit unions and finance companies are particularly significant competitors in the consumer loan market. Banks also compete for deposits with a broad range of other types of investments, including mutual funds and annuities.
Supervision and Regulation
The Corporation and Chemical Bank are subject to extensive supervision and regulation under various federal and state laws. The supervisory and regulatory framework is intended primarily for the protection of depositors and the banking system as a whole, and not for the protection of shareholders and creditors.
Banks are subject to a number of federal and state laws and regulations that have a material impact on their business. These include, among others, minimum capital requirements, state usury laws, state laws relating to fiduciaries, the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (Dodd-Frank Act), the Truth in Lending Act, the Truth in Savings Act, the Equal Credit Opportunity Act, the Fair Housing Act, the Fair Credit Reporting Act, the Expedited Funds Availability Act, the Community Reinvestment Act, the Real Estate Settlement Procedures Act, the USA Patriot Act, the Bank Secrecy Act, the Foreign Account Tax Compliance Act, Office of Foreign Assets Controls regulations, electronic funds transfer laws, redlining laws, predatory lending laws, laws prohibiting unfair and deceptive acts or practices, antitrust laws, environmental laws, anti-money laundering laws and privacy laws. These laws and regulations can have a significant effect on the operating and financial results of banks.

6

A summary of significant elements of some of the laws, regulations and regulatory policies applicable to the Corporation and Chemical Bank follows below. The descriptions are qualified in their entirety by reference to the full text of the statutes, regulations and policies that are described. These statutes, regulations and policies are continually subject to review by Congress, state legislatures and federal and state regulatory agencies. A change in statutes, regulations or regulatory policies applicable to the Corporation and Chemical Bank could have a material effect on the business of the Corporation and Chemical Bank.
Regulatory Agencies
The Corporation is a legal entity separate and distinct from Chemical Bank. The Corporation is regulated by the Federal Reserve Board (FRB) as a financial holding company and a bank holding company under the Bank Holding Company Act of 1956 (BHC Act). The BHC Act provides for general regulation of financial holding companies by the FRB and functional regulation of banking activities by banking regulators. The Corporation is also under the jurisdiction of the Securities and Exchange Commission (SEC) and is subject to the disclosure and regulatory requirements of the Securities Act of 1933 and the Securities Exchange Act of 1934. The Corporation's common stock is traded on The NASDAQ Stock Market® (NASDAQ) under the symbol CHFC and is subject to the NASDAQ Listing Rules.
Chemical Bank is chartered by the State of Michigan and supervised, examined and regulated by the Michigan Department of Insurance and Financial Services (DIFS). Chemical Bank, as a member of the Federal Reserve System, is also supervised, examined and regulated by the FRB. Deposits of Chemical Bank are insured by the Federal Deposit Insurance Corporation (FDIC) to the maximum extent provided by law.
Bank Holding Company Activities
In general, the BHC Act limits the business of bank holding companies to banking, managing or controlling banks and other activities that the FRB has determined to be closely related to the business of banking. In addition, bank holding companies that qualify and elect to be financial holding companies may engage in any activities that are financial in nature or complementary to a financial activity and do not pose a substantial risk to the safety and soundness of depository institutions or the financial system without prior approval of the FRB. Activities that are financial in nature include securities underwriting and dealing, insurance underwriting and making merchant banking investments.
In order for the Corporation to maintain financial holding company status, both the Corporation and Chemical Bank must be categorized as "well-capitalized" and "well-managed" under applicable regulatory guidelines. If the Corporation or Chemical Bank ceases to meet these requirements, the FRB may impose corrective capital and/or managerial requirements and place limitations on the Corporation's ability to conduct the broader financial activities permissible for financial holding companies. In addition, if the deficiencies persist, the FRB may require the Corporation to divest of Chemical Bank. The Corporation and Chemical Bank were both categorized as "well-capitalized" and "well-managed" as of December 31, 2015.
The BHC Act requires prior approval of the FRB for any direct or indirect acquisition of more than 5% of the voting shares of a commercial bank or its parent holding company by the Corporation. In reviewing applications seeking approval of merger and acquisition transactions, the bank regulatory authorities will consider, among other things, the competitive effect and public benefits of the transactions, the capital position of the combined organization, the Corporation's performance record under the Community Reinvestment Act of 1977 (CRA), the Corporation's adherence to banking regulations and fair lending laws and the effectiveness of the subject organizations in combating money laundering activities.
Interstate Banking and Branching
Bank holding companies may acquire banks located in any state in the United States without regard to geographic restrictions or reciprocity requirements imposed by state law. Banks may establish interstate branch networks through acquisitions of other banks. The establishment of de novo interstate branches or the acquisition of individual branches of a bank in another state (rather than the acquisition of an out-of-state bank in its entirety) is allowed only if specifically authorized by state law.
Michigan permits both U.S. and non-U.S. banks to establish branch offices in Michigan. The Michigan Banking Code permits, in appropriate circumstances and with the approval of the DIFS, (1) acquisition of Michigan banks by FDIC-insured banks, savings banks or savings and loan associations located in other states, (2) sale by a Michigan bank of branches to an FDIC-insured bank, savings bank or savings and loan association located in a state in which a Michigan bank could purchase branches of the purchasing entity, (3) consolidation of Michigan banks and FDIC-insured banks, savings banks or savings and loan associations located in other states having laws permitting such consolidation, (4) establishment of branches in Michigan by FDIC-insured banks located in other states, the District of Columbia or U.S. territories or protectorates having laws permitting a Michigan bank to establish a branch in such jurisdiction, and (5) establishment by foreign banks of branches located in Michigan. A Michigan bank holding company may acquire a non-Michigan bank and a non-Michigan bank holding company may acquire a Michigan bank.

Dividends
The Corporation's primary source of funds available to pay dividends to shareholders is from dividends paid to it by Chemical Bank. Federal and state banking laws and regulations limit both the extent to which Chemical Bank can lend or otherwise supply funds to the Corporation and also place certain restrictions on the amount of dividends Chemical Bank may pay to the Corporation.
The Corporation and Chemical Bank are subject to regulatory policies and requirements relating to the payment of dividends, including requirements to maintain capital above regulatory minimums, which could prohibit the payment of dividends under circumstances where the payment could be deemed an unsafe and unsound banking practice. Chemical Bank is required to obtain prior approval from the FRB for the declaration and payment of dividends to the Corporation if the total of all dividends declared in any calendar year will exceed the total of (i) Chemical Bank's net income (as defined by regulation) for that year plus (ii) the retained net income (as defined by regulation) for the preceding two years. In addition, federal regulatory authorities have stated that banking organizations should generally pay dividends only out of current operating earnings. Further, the FRB has indicated that bank holding companies should carefully review their dividend policy and has discouraged payment ratios that are at maximum allowable levels unless both asset quality and capital are very strong. Chemical Bank declared and paid dividends to the Corporation of $56.9 million and $64.5 million in 2015 and 2014, respectively. The Corporation intends to utilize a portion of the proceeds from the dividend from Chemical Bank in 2015 to pay off subordinated debentures, which were acquired as part of the Lake Michigan transaction, during the first quarter of 2016. The Corporation utilized proceeds from the increased dividend from Chemical Bank in 2014 to fund a portion of the cash component of the merger consideration in the Lake Michigan transaction. Dividends received from Chemical Bank in the past are not necessarily indicative of amounts that may be paid or available to be paid in the future.
Source of Strength
Under FRB policy, the Corporation is expected to act as a source of financial strength to Chemical Bank and to commit resources to support Chemical Bank. In addition, if DIFS deems Chemical Bank's capital to be impaired, DIFS may require Chemical Bank to restore its capital by a special assessment on the Corporation as Chemical Bank's only shareholder. If the Corporation failed to pay any assessment, the Corporation's directors would be required, under Michigan law, to sell the shares of Chemical Bank's stock owned by the Corporation to the highest bidder at either a public or private auction and use the proceeds of the sale to restore Chemical Bank's capital.
Capital Requirements
The Corporation and Chemical Bank are subject to regulatory "risk-based" capital guidelines. Failure to meet these capital guidelines could subject the Corporation or Chemical Bank to a variety of enforcement remedies, including issuance of a capital directive, the termination of deposit insurance by the FDIC, a prohibition on accepting brokered deposits, and other restrictions on its business. In addition, Chemical Bank would generally not receive regulatory approval of any application that requires the consideration of capital adequacy, such as a branch or merger application, unless it could demonstrate a reasonable plan to meet the capital requirement within a reasonable period of time.
The Federal Deposit Insurance Corporation Improvement Act (FDICIA) requires, among other things, federal banking agencies to take "prompt corrective action" in respect of depository institutions that do not meet minimum capital requirements. FDICIA sets forth the following five capital categories: "well-capitalized," "adequately-capitalized," "undercapitalized," "significantly-undercapitalized" and "critically-undercapitalized." A depository institution's capital category will depend upon how its capital levels compare with various relevant capital measures as established by regulation, which include Tier 1 and total risk-based capital ratio measures and a leverage capital ratio measure.
Federal banking regulators are required to take specified mandatory supervisory actions and are authorized to take other discretionary actions with respect to institutions in the three undercapitalized categories. The severity of the action depends upon the capital category in which the institution is placed. Subject to a narrow exception, the banking regulator must generally appoint a receiver or conservator for an institution that is critically undercapitalized. An institution in any of the undercapitalized categories is required to submit an acceptable capital restoration plan to its appropriate federal banking agency. An undercapitalized institution is also generally prohibited from paying any dividends, increasing its average total assets, making acquisitions, establishing any branches, accepting or renewing any brokered deposits or engaging in any new line of business, except under an accepted capital restoration plan or with FDIC approval.

In July 2013, the FRB and the FDIC approved final rules implementing the Basel Committee on Banking Supervision's (BCBS) capital guidelines for U.S. banks (commonly known as Basel III). Under Basel III, which began for the Corporation and Chemical Bank on January 1, 2015 and are subject to a phase-in period through January 1, 2019, minimum capital requirements were increased for both the quantity and quality of capital held by the Corporation and Chemical Bank. Basel III added a new common equity Tier 1 capital to risk-weighted assets ratio (CET ratio) of 4.5% and a capital conservation buffer of 2.5% of risk-weighted assets, which when fully phased-in, effectively results in a minimum CET ratio of 7.0%. Basel III also raised the minimum ratio of Tier 1 capital to risk-weighted assets from 4.0% to 6.0% (which, with the capital conservation buffer, effectively results in a minimum Tier 1 capital ratio of 8.5% when fully phased-in) and requires a minimum leverage ratio of 4.0%.
A summary of the actual and minimum Basel III regulatory capital ratios for the Corporation and Chemical Bank as of December 31, 2015 follows:

The capital conservation buffer will be phased in beginning January 1, 2016 at 0.625% and increasing by the same amount each year until fully implemented in January 2019. Failure to maintain the required capital conservation buffer may limit the Corporation's and Chemical Bank's ability to dividends or pay discretionary bonuses, among other things.
At December 31, 2015, the capital ratios of the Corporation and Chemical Bank exceeded the regulatory guidelines for institutions to be categorized as "well-capitalized." Under certain circumstances, the appropriate banking agency may treat a well capitalized, adequately capitalized or undercapitalized institution as if the institution were in the next lower capital category. Additional information on the Corporation and Chemical Bank's capital ratios may be found under Note 20 to the consolidated financial statements under Item 8 of this report.
FDIC Insurance
The FDIC formed the Deposit Insurance Fund (DIF) in accordance with the Federal Deposit Insurance Reform Act of 2005 (Reform Act). The FDIC implemented the Reform Act to create a stronger and more stable insurance system. The FDIC maintains the insurance reserves of the DIF by assessing depository institutions an insurance premium. The DIF insures deposit accounts of Chemical Bank up to a maximum amount per separately insured depositor. Under the Dodd-Frank Act, the maximum amount of federal deposit insurance coverage permanently increased from $100,000 to $250,000 per depositor, per institution.
FDIC insured depository institutions are required to pay deposit insurance premiums based on the risk an institution poses to the DIF. As required by the Dodd-Frank Act, in February 2011, the FDIC finalized rules, effective for assessments occurring after April 1, 2011, which redefine an institution's assessment base as average consolidated total assets minus average Tier 1 capital. These rules also established the general assessment rate for Risk Category 1 institutions, such as Chemical Bank, at 5 to 9 basis points (annualized). Assessments for depository institutions with total assets of $10 billion or more are subject to a different methodology that reflects the institution's overall risk relative to other large institutions. The FDIC also may impose special assessments at any time it estimates that Deposit Insurance Fund reserves will fall to a level that would adversely affect public confidence. The Corporation's FDIC DIF insurance premiums were $5.5 million in 2015, compared to $4.3 million in 2014 and $4.4 million in 2013.
Safety and Soundness Standards
As required by FDICIA, the federal banking agencies' prompt corrective action powers impose progressively more restrictive constraints on operations, management and capital distributions, depending on the category in which an institution is classified. These actions can include: requiring an insured depository institution to adopt a capital restoration plan guaranteed by the institution's parent company; placing limits on asset growth and restrictions on activities, including restrictions on transactions with affiliates; restricting the interest rates the institution may pay on deposits; prohibiting the payment of principal or interest on subordinated debt; prohibiting the holding company from making capital distributions without prior regulatory approval; and, ultimately, appointing a receiver for the institution.

9

The federal banking agencies also have adopted guidelines prescribing safety and soundness standards relating to internal controls and information systems, internal audit systems, loan documentation, credit underwriting, interest rate exposure, asset growth, and compensation and benefits. The federal regulatory agencies may take action against a financial institution that does not meet such standards.
Depositor Preference
The Federal Deposit Insurance Act provides that, in the event of the "liquidation or other resolution" of an insured depository institution, the claims of depositors of the institution, including the claims of the FDIC on behalf of insured depositors, and certain claims for administrative expenses of the FDIC as a receiver, will have priority over other general unsecured claims against the institution. If an insured depository institution fails, insured and uninsured depositors, along with the FDIC, will have priority in payment ahead of unsecured, non-deposit creditors, including depositors whose deposits are payable only outside of the United States and the parent bank holding company, with respect to any extensions of credit they have made to such insured depository institution.
Community Reinvestment Act (CRA)
Banks are subject to the provisions of the CRA. Under the terms of the CRA, the appropriate federal bank regulatory agency is required, in connection with its examination of a bank, to assess such bank's record in meeting the credit needs of the community served by that bank, including low and moderate income neighborhoods, consistent with the safe and sound operation of the institution. Under the CRA, institutions are assigned a rating of "outstanding," "satisfactory," "needs to improve," or "substantial non-compliance." The regulatory agency's assessment of the bank's record is made available to the public. Further, a bank's federal regulatory agency is required to assess the CRA compliance record of any bank that has applied to: (1) obtain deposit insurance coverage for a newly chartered institution, (2) establish a new branch office that will accept deposits, (3) relocate an office, or (4) merge or consolidate with, or acquire the assets or assume the liabilities of, a federally regulated financial institution. In the case of a bank holding company applying for approval to acquire a bank or another bank holding company, the FRB will assess the CRA compliance record of each subsidiary bank of the applicant bank holding company, and such compliance records may be the basis for denying the application. Upon receiving notice that a subsidiary bank is rated less than "satisfactory," a financial holding company will be prohibited from additional activities that are permitted to a financial holding company and from acquiring any company engaged in such activities. Chemical Bank's CRA rating was "outstanding" as of December 31, 2015.
Financial Privacy
Federal banking regulations limit the ability of banks and other financial institutions to disclose non-public information about consumers to nonaffiliated third parties. These limitations require disclosure of privacy policies to consumers and, in some circumstances, allow consumers to prevent disclosure of certain personal information to a nonaffiliated third party. These regulations affect how consumer information is transmitted through diversified financial companies and conveyed to outside vendors.
Anti-Money Laundering and the USA Patriot Act
A major focus of governmental policy on financial institutions has been aimed at combating money laundering and terrorist financing. The USA PATRIOT Act of 2001 (USA Patriot Act) substantially broadened the scope of United States anti-money laundering laws and regulations by imposing significant compliance and due diligence obligations, creating new crimes and penalties and expanding the extra-territorial jurisdiction of the United States. The United States Treasury Department has issued, and in some cases proposed, a number of regulations that apply various requirements of the USA Patriot Act to financial institutions. These regulations impose obligations on financial institutions to maintain appropriate policies, procedures and controls to detect, prevent and report money laundering and terrorist financing and to verify the identity of their customers. Certain of those regulations impose specific due diligence requirements on financial institutions that maintain correspondent or private banking relationships with non-U.S. financial institutions or persons. Failure of a financial institution to maintain and implement adequate programs to combat money laundering and terrorist financing, or to comply with all of the relevant laws or regulations, could have serious legal and reputational consequences for the institution.
Office of Foreign Assets Control Regulation
The United States Treasury Department Office of Foreign Assets Control (OFAC) has imposed economic sanctions that affect transactions with designated foreign countries, nationals and others. OFAC sanctions targeting countries take many different forms. Generally, however, they contain one or more of the following elements: (i) restrictions on trade with or investment in a sanctioned country, including prohibitions on "U.S. persons" engaging in financial transactions relating to making investments in, or providing investment-related advice or assistance to, a sanctioned country; and (ii) a blocking of assets in which the government or specially designated nationals of the sanctioned country have an interest, by prohibiting transfers of property subject to U.S. jurisdiction (including property in the possession or control of U.S. persons). Blocked assets (e.g., property and bank deposits) cannot be paid out, withdrawn, set off or transferred in any manner without a license from OFAC. Failure to comply with these sanctions could have serious legal and reputational consequences.

The Dodd-Frank Act
The Dodd-Frank Act, enacted in July 2010, represents a comprehensive overhaul of the financial services industry within the United States, including establishing the federal Consumer Financial Protection Bureau (CFPB) and requiring the CFPB and other federal agencies to implement many new and significant rules and regulations. The CFPB has issued significant new regulations, which became effective in January 2014, that impact consumer mortgage lending and servicing. In addition, the CFPB has issued regulations, which became effective October 1, 2015, that change the disclosure requirements and forms used under the Truth in Lending Act and the Real Estate Settlement Procedures Act. Compliance with these new laws and regulations and other regulations under consideration by the CFPB have and will likely result in additional costs and could change the products and/or services that are currently being offered, which could be significant and could adversely impact the Corporation's results of operations, financial condition or liquidity.
Incentive Compensation
The regulatory agencies have issued comprehensive guidance on incentive compensation policies intended to ensure that the incentive compensation policies of banking organizations do not undermine the safety and soundness of such organizations by encouraging excessive risk-taking. The guidance, which covers all employees that have the ability to materially affect the risk profile of an organization, either individually or as part of a group, is based upon the key principles that a banking organization's incentive compensation arrangements should (i) provide incentives that do not encourage risk-taking beyond the organization's ability to effectively identify and manage risks, (ii) be compatible with effective internal controls and risk management and (iii) be supported by strong corporate governance, including active and effective oversight by the organization's board of directors.
The FRB reviews, as part of the regular, risk-focused examination process, the incentive compensation arrangements of banking organizations, such as the Corporation, that are not "large, complex banking organizations." The findings will be included in reports of examination. Deficiencies will be incorporated into the organization's supervisory ratings, which can affect the organization's ability to make acquisitions and take other actions. Enforcement actions may be taken against a banking organization if its incentive compensation arrangements, or related risk-management control or governance processes, pose a risk to the organization's safety and soundness and the organization is not taking prompt and effective measures to correct the deficiencies.
Mergers, Acquisitions, Consolidations and Divestitures
The Corporation's current strategy for growth includes strengthening its presence in core markets, expanding into contiguous markets and broadening its product offerings, while taking into account the integration and other risks of growth. The Corporation evaluates strategic acquisition opportunities and conducts due diligence activities in connection with possible transactions. As a result, discussions, and in some cases, negotiations and transactions may take place and future acquisitions involving cash, debt or equity securities may occur, including future acquisitions that may extend beyond contiguous markets. These generally involve payment of a premium over book value and current market price, and therefore, dilution of book value per share will likely occur with any future transaction.

Item 1A. Risk Factors.
The Corporation's business model is subject to many risks and uncertainties. Although the Corporation seeks ways to manage these risks, the Corporation ultimately cannot predict the future or control all of the risks to which it is subject. Actual results may differ materially from management's expectations. Some of these significant risks and uncertainties are discussed below. The risks and uncertainties described below are not the only ones that the Corporation faces. Additional risks and uncertainties of which the Corporation is unaware, or that it currently deems immaterial, also may become important factors that adversely affect the Corporation and its business. If any of these risks were to occur, the Corporation's business, financial condition or results of operations could be materially and adversely affected. If this were to happen, the market price of the Corporation's common stock per share could decline significantly.
Investments in the Corporation's common stock involve risk.
The market price of the Corporation's common stock may fluctuate significantly in response to a number of factors, including, among other things:
•
Variations in quarterly or annual results of operations
•
Changes in dividends paid per share
•
Deterioration in asset quality, including declining real estate values
•
Changes in interest rates
•
Significant acquisitions or business combinations, strategic partnerships, joint ventures or capital commitments by, or involving, the Corporation or its competitors
•
Failure to integrate acquisitions or realize anticipated benefits from acquisitions
•
Regulatory actions, including changes to regulatory capital levels, the components of regulatory capital and how regulatory capital is calculated
•
New regulations that limit or significantly change the Corporation's ability to continue to offer existing banking products
•
Volatility of stock market prices and volumes
•
Issuance of additional shares of common stock or other debt or equity securities of the Corporation
•
Changes in market valuations of similar companies
•
Uncertainties, disruptions and fluctuations in the credit and financial markets, either nationally or globally
•
Changes in securities analysts' estimates of financial performance or recommendations
•
New litigation or contingencies or changes in existing litigation or contingencies
•
New technology used, or services offered, by competitors
•
Breaches in information security systems of the Corporation and/or its customers and competitors
•
Changes in accounting policies or procedures required by standard setting or other regulatory agencies
•
New developments in the financial services industry
•
News reports relating to trends, concerns and other issues in the financial services industry
•
Perceptions in the marketplace regarding the financial services industry, the Corporation and/or its competitors
•
Rumors or erroneous information
•
Geopolitical conditions such as acts or threats of terrorism or military conflicts
The Corporation is subject to lending risk.
A significant source of risk for the Corporation arises from the possibility that losses will be sustained because borrowers, guarantors and related parties may fail to perform in accordance with the terms of their loan agreements. Most loans originated by the Corporation are secured, but some loans are unsecured depending on the nature of the loan. With respect to secured loans, the collateral securing repayment includes a wide variety of real and personal property that may be insufficient to cover the amounts owed. Collateral values are adversely affected by changes in prevailing economic, environmental and other conditions, including declines in the value of real estate, changes in interest rates, changes in monetary and fiscal policies of the federal government, terrorist activity, environmental contamination and other external events.
The Corporation maintains an allowance for loan losses, which is a reserve established through a provision for loan losses charged to net income that represents management's estimate of probable losses that have been incurred within the existing portfolio of loans. The level of the allowance for loan losses reflects management's continuing evaluation of specific credit risks, loan loss experience, current loan portfolio quality, the value of real estate, present economic, political and regulatory conditions and unidentified losses inherent in the current loan portfolio. The determination of the appropriate level of the allowance for loan losses inherently involves a high degree of subjectivity and requires the Corporation to make significant estimates of current credit risks and future trends, all of which may undergo material changes. Deterioration in economic conditions and declines in real estate values affecting borrowers, new information regarding existing loans, identification of additional problem loans and other factors, both within and outside of the Corporation's control, may require an increase in the allowance for loan losses. In addition, bank regulatory agencies periodically review the Corporation's allowance for loan losses and may require an increase in the allowance for loan losses or the recognition of further loan charge-offs, based on judgments different than those of management.

12

Any significant increase in the allowance for loan losses would likely result in a significant decrease in net income and may have a material adverse effect on the Corporation's financial condition and results of operations. See the sections captioned "Allowance for Loan Losses" in Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations and Note 4 - Loans in the notes to consolidated financial statements in Item 8. Financial Statements and Supplementary Data, located elsewhere in this report for further discussion related to the Corporation's process for determining the appropriate level of the allowance for loan losses.
Potential acquisitions or mergers may disrupt the Corporation's business and dilute shareholder value.
The Corporation seeks acquisition or merger partners that are culturally similar and have experienced management and possess either significant market presence or have potential for improved profitability through financial management, economies of scale or expanded services. Acquiring or merging other banks, businesses, or branches involves various risks commonly associated with acquisitions or mergers, including, among other things:
•
Delay in completing an acquisition or merger due to litigation or the regulatory approval process
•
The recording of assets and liabilities of the acquired or merged company at fair value may materially dilute shareholder value at the transaction date and could have a material adverse effect on the Corporation's financial condition and results of operations
•
The time and costs associated with identifying and evaluating potential acquisition or merger targets
•
Potential exposure to unknown or contingent liabilities of the acquired or merged company
•
The estimates and judgments used to evaluate credit, operations, management and market risks with respect to the acquired or merged company may not be accurate
•
Exposure to potential asset quality issues of the acquired or merged company
•
The time and costs of evaluating new markets, hiring experienced local management and opening new offices, and the time lags between these activities and the generation of sufficient assets and deposits to support the costs of the expansion
•
The diversion of the Corporation's management's attention to the negotiation of a transaction, and the integration of the operations and personnel of the combining businesses
•
The introduction of new products and services into the Corporation's business
•
Potential disruption to the Corporation's business
•
The incurrence and possible impairment of goodwill and other intangible assets associated with an acquisition or merger and possible adverse short-term effects on the Corporation's results of operations
•
The possible loss of key employees and customers of the acquired or merged company
•
Difficulty in estimating the value of the acquired or merged company
•
Potential changes in banking or tax laws or regulations that may affect the acquired or merged company
•
Difficulty or unanticipated expense associated with converting the operating systems of the acquired or merged company to those of the Corporation
The transactions may be more expensive to complete and the anticipated benefits, including cost savings and strategic gains, may be significantly harder or take longer to achieve than expected or may not be achieved in their entirety as a result of unexpected factors or events, including economic and financial conditions.
The Corporation regularly evaluates merger and acquisition opportunities and conducts due diligence activities related to possible transactions with other financial institutions and financial services companies. As a result, merger or acquisition discussions and, in some cases, negotiations and transactions may take place and future mergers or acquisitions involving cash, debt or equity securities may occur at any time. Acquisitions and mergers typically involve the payment of a premium over book value, and, therefore, dilution of the Corporation's tangible book value and ownership interest may occur in connection with any future transaction. Furthermore, failure to realize the expected revenue increases, cost savings, increases in geographic or product presence, and/or other projected benefits from an acquisition could have a material adverse effect on the Corporation's financial condition and results of operations, including net income per common share.
Risks related to the Corporation's proposed merger with Talmer Bancorp, Inc. (Talmer)
The Corporation and Talmer have operated and, until the completion of the merger, will continue to operate, independently. The success of the merger, including anticipated benefits and cost savings, will depend, in part, on the Corporation’s and Talmer’s ability to successfully combine and integrate the businesses of the Corporation and Talmer in a manner that permits growth opportunities and does not materially disrupt the existing customer relations or result in decreased revenues due to loss of customers. It is possible that the integration process could result in the loss of key employees, the disruption of either company’s ongoing businesses or inconsistencies in standards, controls, procedures and policies that adversely affect the combined company’s ability to maintain relationships with customers, depositors, clients and employees or to achieve the anticipated benefits and cost savings of the merger. If the combined companies experience difficulties with the integration process, the anticipated benefits of the merger may not be realized fully or at all, or may take longer to realize than expected.

13

The Corporation has incurred, and will continue to incur, substantial expenses in connection with the negotiation and completion of the transaction contemplated by the merger agreement with Talmer. If the merger is not completed, the Corporation would have to recognize these expenses without realizing the expected benefits of the merger. These circumstances could have an adverse effect on the Corporation's business, results of operations and stock price.
Under the merger agreement, both the Corporation and Talmer have agreed not to, subject to certain exceptions generally related to their respective board of directors exercise of fiduciary duties, as set forth in the merger agreement, solicit or initiate, or knowingly facilitate or knowingly encourage, inquiries or proposals with respect to, engage in any discussions or negotiations concerning, or provide any confidential information relating to, any alternative business combination transactions. In addition, the merger agreement contains certain termination rights for both the Corporation and Talmer. If the merger agreement is terminated under certain circumstances, including certain breaches of the merger agreement, the Corporation or Talmer, as applicable, is required to reimburse the other party for its transaction-related expenses up to $3 million. If the merger agreement is terminated under certain circumstances, including termination of the merger agreement to accept an alternative business combination transaction as permitted by and subject to the terms of the merger agreement, the Corporation or Talmer, as applicable, is required to pay the other party a termination fee of $34 million minus any previously reimbursed transaction-related expenses.
Before the merger may be completed, the Corporation and Talmer must obtain approvals from the Board of Governors of the Federal Reserve System. Other approvals, waivers or consents from regulators may also be required. These regulators may impose conditions on the completion of the merger or require changes to the terms of the merger. Although the Corporation and Talmer do not currently expect that any such conditions or changes would be imposed, there can be no assurance that they will not be, and such conditions or changes could have the effect of delaying or preventing completion of the merger or imposing additional costs on or limiting the revenues of the combined company following the merger, any of which might have an adverse effect on the combined company following the merger.
Before the merger may be completed, the Corporation and Talmer must obtain the requisite approval of their respective shareholders. There is no assurance that these approvals will be obtained.
Litigation filed against Talmer, its board of directors and the Corporation could prevent or delay the completion of the merger or result in the payment of damages following completion of the merger.
In connection with the merger, two purported Talmer stockholders have filed putative class action lawsuits against Talmer, its board of directors and the Corporation. Among other remedies, the plaintiffs seek to enjoin the merger. If this litigation is not resolved, these lawsuits could prevent or delay completion of the merger and result in substantial costs to Talmer and the Corporation, including any costs associated with indemnification. Additional lawsuits may be filed against Talmer, the Corporation or the directors and officers of either company in connection with the merger. The defense or settlement of any lawsuit or claim that remains unresolved at the effective time of the merger may adversely affect the combined company's business, financial condition, results of operations, cash flows and market price.
Additional growth will subject the Corporation to additional regulation, increased supervision and increased costs.
The Dodd-Frank Act imposes additional regulatory requirements on institutions with $10 billion or more in assets. The Corporation had $9.2 billion in assets as of December 31, 2015. Additional growth that results in the Corporation having assets of $10 billion or more would subject the Corporation to the following:
•
Supervision, examination and enforcement by the CFPB with respect to consumer financial protection laws;
•
Regulatory stress testing requirements, whereby the Corporation would be required to conduct an annual stress test (using assumptions for baseline, adverse and severely adverse scenarios);
•
A modified methodology for calculating FDIC insurance assessments and potentially higher assessment rates as a result of institutions with $10 billion or more in assets being required to bear a greater portion of the cost of raising the reserve ratio to 1.35% as required by the Dodd-Frank Act;
•
Heightened compliance standards under the Volcker Rule;
•
Enhanced supervision as a larger financial institution; and
•
Under the Durbin Amendment to the Dodd-Frank Act, institutions with $10 billion or more in assets are subject to a cap on the interchange fees that may be charged in certain electronic debit and prepaid card transactions. The maximum permissible interchange fee for electronic debit transactions is the sum of 21 cents per transaction and 5 basis points multiplied by the value of the transaction. In addition, an issuer may charge up to 1 cent on each transaction as a fraud prevention adjustment if the issuer meets certain fraud prevention standards.
The imposition of these regulatory requirements and increased supervision may require additional commitment of financial resources to regulatory compliance and may increase the Corporation's cost of operations. Further, the results of the stress testing process may lead the Corporation to retain additional capital or alter the mix of its capital components.
If the pending merger with Talmer Bancorp, Inc. is completed, then the Corporation will have more than $10 billion in assets and, as a result, will be subject to the additional regulatory requirements, increased supervision and increased costs.

14

The Corporation may face increased pressure from purchasers of its residential mortgage loans to repurchase those loans or reimburse purchasers for losses related to those loans.
The Corporation sells fixed rate long-term residential mortgage loans it originates in the secondary market. Purchasers of residential mortgage loans, such as government sponsored entities, are increasing their efforts to seek to require sellers of residential mortgage loans to either repurchase loans previously sold or reimburse purchasers for losses related to loans previously sold when losses are incurred on a loan previously sold due to actual or alleged failure to strictly conform to the purchaser's purchase criteria. As a result, the Corporation may face increased pressure from purchasers of its residential mortgage loans to repurchase those loans or reimburse purchasers for losses related to those loans and it may face increasing expenses to defend against such claims. If the Corporation is required in the future to repurchase loans previously sold, reimburse purchasers for losses related to loans previously sold, or if it incurs increasing expenses to defend against such claims, the Corporation's financial condition and results of operations would be negatively affected.
The Corporation holds general obligation municipal bonds in its investment securities portfolio. If one or more issuers of these bonds were to become insolvent and default on its obligations under the bonds, it could have a negative effect on the financial condition and results of operations of the Corporation.
Municipal bonds held by the Corporation totaled $525 million at December 31, 2015, and were issued by many different municipalities with no significant concentration in any single municipality. There can be no assurance that the financial conditions of these municipalities will not be materially and adversely affected by future economic conditions. If one or more of the issuers of these bonds were to become insolvent and default on their obligations under the bonds, it could have a negative effect on the financial condition and results of operations of the Corporation.
General economic conditions, and in particular conditions in the State of Michigan, affect the Corporation's business.
The Corporation is affected by general economic conditions in the United States, although most directly within Michigan. The Corporation's success depends primarily on the general economic conditions in the State of Michigan and the specific local markets in which the Corporation operates. The economic conditions in these local markets have a significant impact on the demand for the Corporation's products and services as well as the ability of the Corporation's customers to repay loans, the value of the collateral securing loans and the stability of the Corporation's deposit funding sources. Substantially all of the Corporation's loans are to individuals and businesses in Michigan. Consequently, any prolonged decline in Michigan's economy could have a materially adverse effect on the Corporation's financial condition and results of operations. A significant decline or a prolonged period of the lack of improvement in general economic conditions could impact these local economic conditions and, in turn, have a material adverse effect on the Corporation's financial condition and results of operations.
If the Corporation does not adjust to changes in the financial services industry, its financial performance may suffer.
The Corporation's ability to maintain its financial performance and return on investment to shareholders will depend largely on its ability to continue to grow its loan portfolio and also, in part, on its ability to maintain and grow its core deposit customer base and expand its financial services to its existing and/or new customers. In addition to other banks, competitors include savings and loan associations, credit unions, securities dealers, brokers, mortgage bankers, investment advisors and finance and insurance companies. The increasingly competitive environment is, in part, a result of changes in the economic environment within the State of Michigan, regulation, and changes in technology and product delivery systems. New competitors may emerge to increase the degree of competition for the Corporation's customers and services. Financial services and products are also constantly changing. The Corporation's financial performance will also depend, in part, upon customer demand for its products and services and its ability to develop and offer competitive financial products and services.
Consumers may decide not to use banks to complete their financial transactions.
Technology and other changes are allowing customers to complete financial transactions without the involvement of banks. For example, consumers can now pay bills and transfer funds directly without banks. The process of eliminating banks as intermediaries in financial transactions, known as disintermediation, could result in the loss of fee income, the loss of customer deposits and income generated from those deposits and lending opportunities.
Changes in interest rates could reduce the Corporation's net income and cash flow.
The Corporation's net income and cash flow depends, to a great extent, on the difference between the interest earned on loans and securities and the interest paid on deposits and other borrowings. Market interest rates are beyond the Corporation's control, and they fluctuate in response to general economic conditions, the policies of various governmental and regulatory agencies and competition. Changes in monetary policy, including changes in interest rates and interest rate relationships, will influence the origination of loans, the purchase of investments, the generation of deposits, the interest received on loans and securities and the interest paid on deposits and other borrowings. Any significant adverse effects of changes in interest rates on the Corporation's results of operations, or any substantial, unexpected, prolonged change in market interest rates could have a material adverse effect on the Corporation's financial condition and results of operations. See the sections captioned "Net Interest Income" in Item 7.

The Corporation may be required to pay additional deposit insurance premiums to the FDIC, which could negatively impact earnings.
Depending upon the magnitude of future losses that the FDIC deposit insurance fund suffers, there can be no assurance that there will not be additional premium increases or assessments in order to replenish the fund. The FDIC may need to set a higher base rate schedule based on future financial institution failures and updated failure and loss projections. Potentially higher FDIC assessment rates than those currently projected or special assessments could have an adverse impact on the Corporation's financial condition and results of operations.
The Corporation is subject to liquidity risk in its operations, which could adversely affect its ability to fund various obligations.
Liquidity risk is the possibility of being unable to meet obligations as they come due or capitalize on growth opportunities as they arise because of an inability to liquidate assets or obtain adequate funding on a timely basis, at a reasonable cost and within acceptable risk tolerances. Liquidity is required to fund various obligations, including credit obligations to borrowers, loan originations, withdrawals by depositors, repayment of debt, dividends to shareholders, operating expenses and capital expenditures. Liquidity is derived primarily from retail deposit growth and earnings retention, principal and interest payments on loans and investment securities, net cash provided from operations and access to other funding. If the Corporation is unable to maintain adequate liquidity, then its business, financial condition and results of operations would be negatively effected.
Evaluation of investment securities for other-than-temporary impairment involves subjective determinations and could materially impact the Corporation's financial condition and results of operations.
The evaluation of impairments is a quantitative and qualitative process, which is subject to risks and uncertainties and is intended to determine whether declines in the fair value of investments should be recognized in current period earnings. The risks and uncertainties include changes in general economic conditions, the issuer's net income, projected net income and financial condition or future recovery prospects, the effects of changes in interest rates or credit spreads and the expected recovery period. Estimating future cash flows involves incorporating information received from third-party sources and making internal assumptions and judgments regarding the future performance of the underlying collateral and/or value of the underlying asset and also assessing the probability that an adverse change in future cash flows has occurred. The determination of the amount of other-than-temporary impairments is based upon the Corporation's quarterly evaluation and assessment of known and inherent risks associated with the respective asset class. Such evaluations and assessments are revised as conditions change and new information becomes available.
Additionally, the Corporation's management considers a wide range of factors about the security issuer and uses judgment in evaluating the cause of the decline in the estimated fair value of the security and in assessing the prospects for recovery. Inherent in management's evaluation of the security are assumptions and estimates about the operations of the issuer and its future earnings potential. Considerations in the impairment evaluation process include, but are not limited to: (i) the length of time and the extent to which the market value has been less than cost or amortized cost; (ii) the potential for impairments of securities when the issuer is experiencing significant financial difficulties; (iii) the potential for impairments in an entire industry sector or sub-sector; (iv) the potential for impairments in certain economically depressed geographic locations; (v) the potential for impairments of securities where the issuer, series of issuers or industry has suffered a catastrophic type of loss or has exhausted natural resources; (vi) the Corporation's intent and ability to retain the investment for a period of time sufficient to allow for the recovery of its value; (vii) unfavorable changes in forecasted cash flows on residential mortgage-backed and asset-backed securities; and (viii) other subjective factors, including concentrations and information obtained from regulators and rating agencies. Impairments to the carrying value of the Corporation's investment securities may need to be taken in the future, which could have a material adverse effect on the Corporation's financial condition and results of operations.
The Corporation may be required to recognize an impairment of its goodwill or core deposit intangible assets, or to establish a valuation allowance against its deferred income tax assets, which could have a material adverse effect on the Corporation's financial condition and results of operations.
Goodwill represents the excess of the amounts paid to acquire subsidiaries over the fair value of their net assets at the date of acquisition. The Corporation tests goodwill at least annually for impairment. Substantially all of the Corporation's goodwill at December 31, 2015 was recorded on the books of Chemical Bank. The fair value of Chemical Bank is impacted by the performance of its business and other factors. Core deposit intangible (CDI) assets represent the estimated value of stable customer deposits, excluding time deposits, acquired in business combinations, that provide a source of funds that are below market interest rates. The Corporation amortizes its CDI assets over the estimated period the corresponding customer deposits are expect to exist. The Corporation tests its CDI assets periodically for impairment. If the Corporation experiences higher than expected deposit run-off, its CDI assets could be impaired. If it is determined that the the Corporation's goodwill or CDI assets have been impaired, the Corporation must recognize a write-down by the amount of the impairment, with a corresponding charge to net income. Such

16

write-downs could have a material adverse effect on the Corporation's financial condition and results of operations. At December 31, 2015, the Corporation had $287 million of goodwill, representing 28% of shareholders' equity. The Corporation had $27 million of CDI assets at December 31, 2015.
Deferred income tax represents the tax effect of the differences between the book and tax basis of assets and liabilities. Deferred tax assets are assessed periodically by management to determine if they are realizable. Factors in management's determination include the performance of the Corporation, including the ability to generate taxable net income. If, based on available information, it is more-likely-than-not that the deferred income tax asset will not be realized, then a valuation allowance must be established with a corresponding charge to net income. As of December 31, 2015, the Corporation did not carry a valuation allowance against its deferred tax assets. Future facts and circumstances may require a valuation allowance. Charges to establish a valuation allowance with respect to the Corporation's deferred tax assets could have a material adverse effect on the its financial condition and results of operations.
If the Corporation is required to recognize a valuation allowance with respect to its mortgage servicing rights asset, it could have a material adverse effect on the Corporation's financial condition and results of operations.
At December 31, 2015, the Corporation's mortgage servicing rights (MSR) asset had a book value of $11.1 million and a fair value of approximately $15.5 million. The Corporation amortizes its MSR asset in proportion to and over the period of corresponding net servicing income. The Corporation was not required to recognize a valuation allowance at December 31, 2015 with respect to its MSR asset. If the Corporation is required to recognize a valuation allowance with respect to its MSR asset in the future, the Corporation's financial condition and results of operations could be negatively affected.
The Corporation may be a defendant in a variety of litigation and other actions, which may have a material adverse effect on the Corporation's financial condition and results of operations.
The Corporation and Chemical Bank are regularly involved in a variety of litigation arising out of the normal course of business. The Corporation's insurance may not cover all claims that may be asserted against it, and any claims asserted against it, regardless of merit or eventual outcome, may harm its reputation or cause the Corporation to incur unexpected expenses, which could be material in amount. Should the ultimate expenses, judgments or settlements in any litigation exceed the Corporation's insurance coverage, they could have a material adverse effect on the Corporation's financial condition and results of operations. In addition, the Corporation may not be able to obtain appropriate types or levels of insurance in the future, nor may it be able to obtain adequate replacement policies with acceptable terms, if at all.
Environmental liability associated with commercial lending could result in losses.
In the course of its business, the Corporation may acquire, through foreclosure, properties securing loans it has originated or purchased that are in default. Particularly in commercial real estate lending, there is a risk that hazardous substances could be discovered on these properties. In this event, the Corporation might be required to remove these substances from the affected properties at the Corporation's sole cost and expense. The cost of this removal could substantially exceed the value of affected properties. The Corporation may not have adequate remedies against the prior owner or other responsible parties and could find it difficult or impossible to sell the affected properties. These events could have an adverse effect on the Corporation's business, results of operations and financial condition.
The Corporation depends upon the accuracy and completeness of information about customers.
In deciding whether to extend credit to customers, the Corporation relies on information provided to it by its customers, including financial statements and other financial information. The Corporation may also rely on representations of customers as to the accuracy and completeness of that information and on reports of independent auditors on financial statements. The Corporation's financial condition and results of operations could be negatively impacted to the extent that the Corporation extends credit in reliance on financial statements that do not comply with generally accepted accounting principles or that are misleading or other information provided by customers that is false or misleading.
The Corporation operates in a highly competitive industry and market area.
The Corporation faces substantial competition in all areas of its operations from a variety of different competitors, many of which are larger and may have more financial resources. Such competitors primarily include national and regional banks within the various markets where the Corporation operates, as well as internet banks. The Corporation also faces competition from many other types of financial institutions, including savings and loan associations, credit unions, finance companies, brokerage firms, insurance companies and other financial intermediaries. The financial services industry could become even more competitive as a result of legislative, regulatory and technological changes and continued consolidation. Banks, securities firms and insurance companies can merge under the umbrella of a financial holding company, which can offer virtually any type of financial service, including banking, securities underwriting, insurance (both agency and underwriting) and merchant banking. The Corporation competes with these institutions both in attracting deposits and in making new loans. Technology has lowered barriers to entry into the market and made it possible for non-banks to offer products and services traditionally provided by banks, such as automatic

17

transfer and automatic payment systems. Many of the Corporation's competitors have fewer regulatory constraints and may have lower cost structures, such as credit unions that are not subject to federal income tax. Due to their size, many competitors may be able to achieve economies of scale and, as a result, may offer a broader range of products and services as well as better pricing for those products and services than the Corporation can.
The Corporation's ability to compete successfully depends on a number of factors, including, among other things:
•
The ability to develop, maintain and build long-term customer relationships based on quality service, high ethical standards and safe, sound assets
•
The ability to expand the Corporation's market position
•
The ability to keep up-to-date with technological advancements in both delivering new products and maintaining existing products, while continuing to invest in cybersecurity and control operating costs
•
The scope, relevance and pricing of products and services offered to meet customer needs and demands
•
The rate at which the Corporation introduces new products and services relative to its competitors
•
Customer satisfaction with the Corporation's level of service
•
Industry and general economic trends
Failure to perform in any of these areas could significantly weaken the Corporation's competitive position, which could adversely affect the Corporation's growth and profitability and have a material adverse effect on the Corporation's financial condition and results of operations.
If the Corporation loses members of its senior management team upon whom it is dependent, it may be less effective in managing its operations and may have more difficulty achieving its strategic objectives.
The Corporation believes its success depends on the continued service of its key executives. Although the Corporation currently intends to retain its existing management, it cannot provide assurances that these individuals will remain with the Corporation. The unexpected loss of the services of one or more of the Corporation's key executives or its inability to find suitable replacements within a reasonable period of time following any such loss, could have a material adverse effect on the Corporation's ability to execute its business strategy and, therefore, have a material adverse effect on its financial condition and results of operations.
Legislative or regulatory changes or actions, or significant litigation, could adversely impact the Corporation or the businesses in which it is engaged.
The financial services industry is extensively regulated. The Corporation and Chemical Bank are subject to extensive state and federal regulation, supervision and legislation that govern almost all aspects of their operations. Laws and regulations may change from time to time and are primarily intended for the protection of consumers, depositors and the deposit insurance fund, and not to benefit the Corporation's shareholders. The impact of any changes to laws and regulations or other actions by regulatory agencies may negatively impact the Corporation or its ability to increase the value of its business. Regulatory authorities have extensive discretion in connection with their supervisory and enforcement activities, including the imposition of restrictions on the operation of an institution, the classification of assets by the institution and the adequacy of an institution's allowance for loan losses. Future regulatory changes or accounting pronouncements may increase the Corporation's regulatory capital requirements or adversely affect its regulatory capital levels. Additionally, actions by regulatory agencies or significant litigation against the Corporation or Chemical Bank could require the Corporation to devote significant time and resources to defending its business and may lead to penalties that materially affect the Corporation and its shareholders.
If the Corporation cannot raise additional capital when needed, its ability to further expand its operations through organic growth and acquisitions could be materially impaired.
The Corporation is required by federal and state regulatory authorities to maintain specified levels of capital to support its operations. The Corporation may need to raise additional capital to support its continued growth or in response to regulatory requirements. The Corporation's ability to raise additional capital will depend on conditions in the capital markets at that time, which are outside the Corporation's control, and on its financial performance. The Corporation cannot assure that it will be able to raise additional capital in the future on terms acceptable to the Corporation. If the Corporation cannot raise additional capital when needed, its ability to further expand its operations through organic growth and acquisitions could be materially limited.
The soundness of other financial institutions could adversely affect the Corporation.
The Corporation's ability to engage in routine funding transactions could be adversely affected by the actions and commercial soundness of other financial institutions. Financial services institutions are interrelated as a result of trading, clearing, counterparty or other relationships. The Corporation has exposure to many different industries and counterparties, and it routinely executes transactions with counterparties in the financial services industry. As a result, defaults by, or even rumors or questions about, one or more financial services institutions, or the financial services industry generally, could lead to losses or defaults by the Corporation or by other institutions. Many of these transactions expose the Corporation to credit risk in the event of default of the Corporation's counterparty or client. In addition, the Corporation's credit risk may be exacerbated when the collateral that it holds cannot be

18

realized or is liquidated at prices insufficient to recover the full amount of the loan. The Corporation can give no assurance that any such losses would not materially and adversely affect its business, financial condition or results of operations.
The Corporation's controls and procedures may fail or be circumvented.
Management regularly reviews and updates the Corporation's internal controls and corporate governance policies and procedures. Any system of controls, however well designed and operated, is based in part on certain assumptions and can provide only reasonable, not absolute, assurances that the objectives of the system are met. A significant failure or circumvention of the Corporation's controls and procedures or failure to comply with regulations related to controls and procedures could have a material adverse effect on the Corporation's business, results of operations and financial condition.
Unauthorized disclosure of sensitive or confidential client or customer information, whether through a breach of computer systems or otherwise, could severely harm the Corporation's business.
As part of its business, the Corporation collects, processes and retains sensitive and confidential client and customer information on behalf of itself and other third parties. Despite the security measures the Corporation has in place for its facilities and systems, and the security measures of its third party service providers, the Corporation may be vulnerable to security breaches, acts of vandalism, computer viruses, misplaced or lost data, programming and/or human errors or other similar events. Any security breach involving the misappropriation, loss or other unauthorized disclosure of confidential customer information, whether by the Corporation or by its vendors, could severely damage the Corporation's reputation, expose it to the risks of litigation and liability, disrupt the Corporation's operations and have a material adverse effect on the Corporation's business.
The Corporation's information systems may experience an interruption or breach in security.
The Corporation relies heavily on communications and information systems to conduct its business and deliver its products. Any failure, interruption or breach in security of these systems could result in failures or disruptions in the Corporation's customer relationship management, general ledger, deposit, loan and other systems. While the Corporation has policies and procedures designed to prevent or limit the effect of the failure, interruption or security breach of its information systems, there can be no assurance that any such failures, interruptions or security breaches of the Corporation's information systems or its customers' information or computer systems would not damage the Corporation's reputation, result in a loss of customer business, subject the Corporation to additional regulatory scrutiny, or expose the Corporation to civil litigation and financial liability, any of which could have a material adverse effect on the Corporation's financial condition and results of operations.
Severe weather, natural disasters, acts of war or terrorism and other external events could significantly impact the Corporation's business.
Severe weather, natural disasters, acts of war or terrorism and other adverse external events could have a significant impact on the Corporation's ability to conduct business. Such events could affect the stability of the Corporation's deposit base, impair the ability of borrowers to repay outstanding loans, impair the value of collateral securing loans, cause significant property damage, result in loss of revenue and/or cause the Corporation to incur additional expenses. Although management has established disaster recovery policies and procedures, the occurrence of any such event in the future could have a material adverse effect on the Corporation's business, financial condition and results of operations.
The Corporation may issue debt and equity securities that are senior to the Corporation's common stock as to distributions and in liquidation, which could negatively affect the value of the Corporation's common stock.
In the future, the Corporation may increase its capital resources by entering into debt or debt-like financing or issuing debt or equity securities, which could include issuances of senior notes, subordinated notes, preferred stock or common stock. In the event of the Corporation's liquidation, its lenders and holders of its debt securities and preferred stock would receive a distribution of the Corporation's available assets before distributions to the holders of the Corporation's common stock. The Corporation's decision to incur debt and issue securities in future offerings may depend on market conditions and other factors beyond its control. The Corporation cannot predict or estimate the amount, timing or nature of its future offerings and debt financings. Future offerings could reduce the value of shares of the Corporation's common stock and dilute a shareholder's interest in the Corporation.
The Corporation relies on dividends from Chemical Bank for most of its revenue.
The Corporation is a separate and distinct legal entity from Chemical Bank. It receives substantially all of its revenue from dividends from Chemical Bank. These dividends are the principal source of funds to pay cash dividends on the Corporation's common stock. Various federal and/or state laws and regulations limit the amount of dividends that Chemical Bank may pay to the Corporation. In the event Chemical Bank is unable to pay dividends to the Corporation, the Corporation may not be able to pay cash dividends on its common stock. The earnings of Chemical Bank have been the principal source of funds to pay cash dividends to shareholders. Over the long-term, cash dividends to shareholders are dependent upon earnings, as well as capital requirements, regulatory restraints and other factors affecting Chemical Bank. See the section captioned "Supervision and Regulation" in Item 1. Business and Note 20 - Regulatory Capital and Reserve Requirements in the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data, which are located elsewhere in this report.

The earnings of Chemical Bank are the principal source of funds for the Corporation to pay cash dividends to its shareholders. Accordingly, cash dividends are dependent upon the earnings, capital needs, regulatory constraints, and other factors affecting Chemical Bank. See Note 20 to the consolidated financial statements in Item 8 of this report for a discussion of such limitations. The Corporation has paid regular cash dividends every quarter since it began operation as a bank holding company in 1973. Based on the financial condition of the Corporation at December 31, 2015, management expects the Corporation to pay quarterly cash dividends on its common shares in 2016. However, there can be no assurance as to future dividends because they are dependent on the Corporation's future earnings, capital requirements and financial condition, and may require regulatory approval. On January 20, 2016, the Corporation announced that the board of directors declared a first quarter 2016 cash dividend of $0.26 per share, payable on March 18, 2016.
The following table summarizes the quarterly cash dividends paid to shareholders over the past five years.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations
BUSINESS OF THE CORPORATION
Chemical Financial Corporation (Corporation) is a financial holding company headquartered in Midland, Michigan with its business concentrated in a single industry segment - commercial banking. The Corporation, through its wholly-owned subsidiary bank, Chemical Bank, offers a full range of traditional banking and fiduciary products and services. These products and services include business and personal checking accounts, savings and individual retirement accounts, time deposit instruments, electronically accessed banking products, residential and commercial real estate financing, commercial lending, consumer financing, debit cards, safe deposit box services, money transfer services, automated teller machines, access to insurance and investment products, corporate and personal wealth management services and other banking services.
The principal markets for the Corporation's products and services are communities in Michigan where the branches of Chemical Bank are located and the areas immediately surrounding those communities. As of December 31, 2015, Chemical Bank served these markets through 185 banking offices located in 47 counties across Michigan's lower peninsula. In addition to its banking offices, Chemical Bank operated three loan production offices and over 200 automated teller machines, both on- and off-bank premises. Chemical Bank operates through an internal organizational structure of four regional banking units. Chemical Bank's regional banking units are collections of branch banking offices organized by geographical regions within the State of Michigan.
The principal source of revenue for the Corporation is interest and fees on loans, which accounted for 73% of total revenue in 2015, 72% of total revenue in 2014 and 71% of total revenue in 2013. Interest on investment securities, service charges and fees on deposit accounts and wealth management revenue are also significant sources of revenue, which combined, accounted for 17% of total revenue in 2015 and 19% of total revenue in both 2014 and 2013. Revenue is influenced by overall economic factors including market interest rates, business and consumer spending, consumer confidence and competitive conditions in the marketplace.
MERGERS, ACQUISITIONS AND BRANCH CLOSINGS
Pending Merger with Talmer Bancorp, Inc.
On January 25, 2016, the Corporation entered into an Agreement and Plan of Merger with Talmer Bancorp, Inc. (Talmer). Under the terms of the merger agreement, each Talmer shareholder will receive $1.61 in cash and 0.4725 shares of the Corporation's common stock for each share of Talmer common stock, subject to adjustment in limited circumstances. Based on the 30-day volume weighted price per share of the Corporation's common stock as of January 25, 2016, the merger had a transaction value of approximately $1.1 billion. Following the completion of the merger, the Corporation intends to consolidate Talmer's wholly-owned subsidiary bank, Talmer Bank and Trust, with and into Chemical Bank. At December 31, 2015, Talmer had total assets of $6.6 billion, total loans of $4.8 billion and total deposits of $5.0 billion, including brokered deposits of $229 million. Talmer Bank and Trust is a full service community bank offering a full suite of commercial banking, retail banking, mortgage banking, wealth management and trust services to small and medium-sized businesses and individuals through 81 full service banking offices located primarily within southeast Michigan and northeast Ohio, as well as west Michigan, northeast Michigan, Chicago, Illinois, northern Indiana, and Las Vegas, Nevada. Completion of the merger is subject to regulatory approval and the approval of the Corporation's and Talmer's shareholders, in addition to satisfaction of other customary closing conditions.
Acquisition of Lake Michigan Financial Corporation
On May 31, 2015, the Corporation acquired all of the outstanding stock of Lake Michigan Financial Corporation (Lake Michigan) for total consideration of $187.4 million, which included stock consideration of $132.9 million and cash consideration of $54.5 million. As a result of the acquisition, the Corporation issued approximately 4.3 million shares of its common stock, based on an exchange ratio of 1.326 shares of its common stock, and paid $16.64 in cash, for each share of Lake Michigan common stock outstanding. Lake Michigan, a bank holding company, owned The Bank of Holland and The Bank of Northern Michigan, which combined operated five banking offices in Holland, Grand Haven, Grand Rapids, Petoskey and Traverse City, Michigan. The Bank of Holland and The Bank of Northern Michigan were consolidated with and into Chemical Bank on November 13, 2015. The acquisition of Lake Michigan resulted in increases in the Corporation's total assets of $1.24 billion, including total loans of $986 million, and total deposits of $925 million, as of the acquisition date. In connection with the acquisition of Lake Michigan, the Corporation recorded $102 million of goodwill, which was primarily attributable to the synergies and economies of scale expected from combining the operations of the Corporation and Lake Michigan. In addition, the Corporation recorded $8.6 million of core deposit and other intangible assets in conjunction with the acquisition.
Acquisition expenses associated with the acquisition of Lake Michigan totaled $5.5 million during 2015, which reduced net income per common share by $0.11 in 2015.

24

Acquisition of Monarch Community Bancorp, Inc.
On April 1, 2015, the Corporation acquired all of the outstanding stock of Monarch Community Bancorp, Inc. (Monarch) in an all-stock transaction valued at $27.2 million. As a result of the acquisition, the Corporation issued 860,575 shares of its common stock based on an exchange ratio of 0.0982 shares of its common stock for each share of Monarch common stock outstanding. Monarch, a bank holding company, owned Monarch Community Bank, which operated five full service branch offices in Coldwater, Marshall, Hillsdale and Union City, Michigan. Monarch Community Bank was consolidated with and into Chemical Bank on May 8, 2015. The acquisition of Monarch resulted in increases in the Corporation's total assets of $183 million, including total loans of $122 million, and total deposits of $144 million, as of the acquisition date. In connection with the acquisition of Monarch, the Corporation recorded $5.3 million of goodwill, which was primarily attributable to the synergies and economies of scale expected from combining the operations of the Corporation and Monarch. In addition, the Corporation recorded $1.9 million of core deposit intangible assets in conjunction with the acquisition.
Acquisition expenses associated with the acquisition of Monarch totaled $2.3 million during 2015, which reduced net income per common share by $0.04 in 2015.
Acquisition of Northwestern Bancorp, Inc.
On October 31, 2014, the Corporation acquired all of the outstanding stock of Northwestern Bancorp, Inc. (Northwestern) for total cash consideration of $121 million. Northwestern, a bank holding company which owned Northwestern Bank, provided traditional banking services and products through 25 banking offices serving communities in the northwestern lower peninsula of Michigan. At the acquisition date, Northwestern added total assets of $815 million, including total loans of $475 million, and total deposits of $794 million, to the Corporation. Northwestern Bank was consolidated with and into Chemical Bank as of the acquisition date. In connection with the acquisition of Northwestern, the Corporation recorded $60 million of goodwill, which was primarily attributable to the synergies and economies of scale expected from combining the operations of the Corporation and Northwestern. In addition, the Corporation recorded $12.9 million of core deposit intangible assets in conjunction with the acquisition.
Acquisition expenses associated with the acquisition of Northwestern totaled $5.8 million during 2014, which reduced net income per common share by $0.14 in 2014.
Acquisition of 21 Branches
On December 7, 2012, Chemical Bank acquired 21 branches from Independent Bank, a subsidiary of Independent Bank Corporation (branch acquisition transaction). In addition to the branch offices, which are located in the northeast and Battle Creek regions of Michigan, the acquisition included $404 million in deposits and $44 million in loans. The purchase price of the branch offices, including equipment, was $8.1 million and the Corporation paid a premium on deposits of $11.5 million, or approximately 2.85% of total deposits acquired. The loans were purchased at a discount of 1.75%. In connection with the acquisition of the branches, the Corporation recorded goodwill of $6.8 million, which represented the excess of the purchase price over the fair value of identifiable net assets acquired, and other intangible assets attributable to customer core deposits of $5.6 million.
Acquisition of O.A.K. Financial Corporation
On April 30, 2010, the Corporation acquired O.A.K. Financial Corporation (OAK) for total consideration of $83.7 million. As a result of the acquisition, the Corporation issued 3.5 million shares of its common stock. OAK, a bank holding company which owned Byron Bank, provided traditional banking services and products through 14 banking offices serving communities in Ottawa, Allegan and Kent counties in west Michigan. As of the April 30, 2010 acquisition date, OAK added total assets of $820 million, including total loans of $627 million, and total deposits of $693 million, including brokered deposits of $193 million, to the Corporation. On July 23, 2010, Byron Bank was consolidated with and into Chemical Bank. In connection with the acquisition of OAK, the Corporation recorded goodwill of $43.5 million. Goodwill recorded was primarily attributable to the synergies and economies of scale expected from combining the operations of the Corporation and OAK. In addition, the Corporation recorded other intangible assets in conjunction with the acquisition of $9.8 million.
Branch Closings
In conjunction with the consolidation of The Bank of Northern Michigan with and into Chemical Bank during the fourth quarter of 2015, the Corporation closed two branches in communities where The Bank of Northern Michigan and Chemical Bank had overlapping branches. In conjunction with the acquisition of Monarch during the second quarter of 2015, the Corporation closed two branches in communities where Monarch Community Bank and Chemical Bank had overlapping branches. In conjunction with the acquisition of Northwestern during the fourth quarter of 2014, the Corporation closed four branches in communities where Northwestern Bank and Chemical Bank had overlapping branches. Expenses associated with these eight branch office locations were not significant, as the majority of the employees of these eight closed branch offices were transferred to other nearby Chemical Bank branch locations or other open positions within Chemical Bank.

CRITICAL ACCOUNTING POLICIES
The Corporation's consolidated financial statements are prepared in accordance with United States generally accepted accounting principles (GAAP), Securities and Exchange Commission (SEC) rules and interpretive releases and general practices within the industry in which the Corporation operates. Application of these principles requires management to make estimates, assumptions and complex judgments that affect the amounts reported in the consolidated financial statements and accompanying notes. These estimates, assumptions and judgments are based on information available as of the date of the financial statements; accordingly, as this information changes, the consolidated financial statements could reflect different estimates, assumptions and judgments. Actual results could differ significantly from those estimates. Certain policies inherently have a greater reliance on the use of estimates, assumptions and judgments and, as such, have a greater possibility of producing results that could be materially different than originally reported. The Corporation utilizes third-party sources to assist with developing estimates, assumptions and judgments regarding certain amounts reported in the consolidated financial statements and accompanying notes. When third-party sources are utilized, the Corporation's management remains responsible for complying with GAAP. To execute management's responsibilities, the Corporation has processes in place to develop an understanding of the third-party methodologies and to design and implement specific internal controls over valuation.
The significant accounting policies followed by the Corporation are presented in Note 1 to the consolidated financial statements included in Item 8 of this report. These policies, along with the disclosures presented in the other notes to the consolidated financial statements and in "Management's Discussion and Analysis of Financial Condition and Results of Operations," provide information on how significant assets and liabilities are measured in the consolidated financial statements and how those measurements are determined. Based on the techniques used and the sensitivity of financial statement amounts to the methods, estimates and assumptions underlying those amounts, management has identified the determination of the allowance for loan losses, accounting for business combinations (including acquired loans), pension plan accounting, income and other taxes, the evaluation of goodwill impairment and fair value measurements to be the accounting areas that require the most subjective or complex judgments, and as such, could be most subject to revision as new or additional information becomes available or circumstances change, including overall changes in the economic climate and/or market interest rates. Management reviews the following critical accounting policies with the Audit Committee of the board of directors at least annually.
Allowance for Loan Losses
The allowance for loan losses (allowance) is calculated with the objective of maintaining a reserve sufficient to absorb losses inherent in the loan portfolio. Loans represent the Corporation's largest asset type on the consolidated statements of financial position. The determination of the amount of the allowance is considered a critical accounting estimate because it requires significant judgment and the use of estimates related to the amount and timing of expected cash flows and collateral values on impaired loans, estimated losses on non-impaired loans in the commercial loan portfolio (comprised of commercial, commercial real estate, real estate construction and land development loans) and on pools of homogeneous loans based on historical loss experience, and consideration of current economic trends and conditions, all of which may be susceptible to significant change. The principal assumption used in deriving the allowance is the estimate of a loss percentage for each type of loan. In determining the allowance and the related provision for loan losses, the Corporation considers four principal elements: (i) valuation allowances based upon probable losses identified during the review of impaired loans in the commercial loan portfolio, (ii) reserves established for adversely-rated loans in the commercial loan portfolio and nonaccrual residential mortgage, consumer installment and home equity loans, (iii) reserves, by loan classes, on all other loans based principally on a five-year historical loan loss experience, loan loss trends and giving consideration to estimated loss emergence periods, and (iv) a reserve for qualitative factors that take into consideration risks inherent in the originated loan portfolio that differ from historical loan loss experience. It is extremely difficult to identify and accurately measure the amount of losses that are inherent in the Corporation's loan portfolio. The Corporation uses a defined methodology to quantify the necessary allowance and related provision for loan losses, but there can be no assurance that the methodology will successfully identify and estimate all of the losses that are inherent in the loan portfolio. Such methodology utilizes historical loss experience (net charge-offs) adjusted for qualitative factors, including trends in credit quality, composition of and growth in the Corporation's loan portfolio, and the overall economic environment in the Corporation's markets. These qualitative factors include many estimates and judgments. As a result, the Corporation could record future provisions for loan losses that may be significantly different than the levels that have been recorded in the three-year period ended December 31, 2015. Notes 1 and 4 to the consolidated financial statements further describe the methodology used to determine the allowance. In addition, a discussion of the factors driving changes in the amount of the allowance is included under the subheading "Allowance for Loan Losses" in "Management's Discussion and Analysis of Financial Condition and Results of Operations."
The Corporation has a loan review function that is independent of the loan origination function. At least annually, the loan review function reviews management's evaluation of the allowance and performs a detailed credit quality review, including analysis of collateral values, of loans in the commercial loan portfolio, particularly focusing on larger balance loans and loans that have deteriorated below certain levels of credit risk. In many cases, the estimate of collateral values includes significant judgments and assumptions.

26

Accounting for Business Combinations
Pursuant to the guidance of Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 805, Business Combinations (ASC 805), the Corporation recognizes assets acquired, including identified intangible assets, and the liabilities assumed in acquisitions at their fair values as of the acquisition date, with the acquisition-related transaction and restructuring costs expensed in the period incurred. Determining the fair value of assets acquired and liabilities assumed often involves estimates based on third-party valuations, such as appraisals, or internal valuations based on discounted cash flow analyses or other valuation techniques that may include estimates of attrition, inflation, asset growth rates, discount rates, multiples of earnings or other relevant factors. In addition, the determination of the useful lives over which an intangible asset will be amortized is subjective.
Accounting for Acquired Loans
ASC Topic 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality (ASC 310-30), provides the GAAP guidance for accounting for loans acquired in a business combination that have experienced a deterioration in credit quality from origination to acquisition for which it is probable that the purchaser will be unable to collect all contractually required payments receivable, including both principal and interest.
Loans purchased with evidence of credit deterioration since origination and for which it is probable that all contractually required payments will not be collected are considered to be impaired. In the assessment of credit quality deterioration, the Corporation must make numerous assumptions, interpretations and judgments using internal and third-party credit quality information to determine whether or not it is probable that the Corporation will be able to collect all contractually required payments. This is a point in time assessment and inherently subjective due to the nature of the available information and judgment involved. Evidence of credit quality deterioration as of the acquisition date may include statistics such as past due and nonaccrual status, recent borrower credit scores and loan-to-value percentages. Those loans that qualify under ASC 310-30 are recorded at fair value at acquisition, which involves estimating the expected cash flows to be received. Accordingly, the associated allowance for loan losses related to these loans is not carried over at the acquisition date. ASC 310-30 also allows investors to aggregate acquired loans into loan pools that have common risk characteristics and use a composite interest rate and expectation of cash flows to be collected for the loan pools. The Corporation understands, as outlined in the American Institute of Certified Public Accountants' open letter to the Office of the Chief Accountant of the SEC dated December 18, 2009, and pending further standard setting, that for acquired loans that do not meet the scope criteria of ASC 310-30, a company may elect to account for such acquired loans pursuant to the provisions of either ASC Topic 310-20, Nonrefundable Fees and Other Costs, or ASC 310-30. The Corporation elected to apply ASC 310-30, by analogy, to loans acquired in the Lake Michigan, Monarch, Northwestern and OAK acquisitions that were determined not to have deteriorated credit quality, and therefore, did not meet the scope criteria of ASC 310-30. Accordingly, the Corporation follows the accounting and disclosure guidance of ASC 310-30 for these loans. Notes 1, 2 and 4 to the consolidated financial statements contain additional information related to loans acquired in the Lake Michigan, Monarch, Northwestern and OAK acquisitions.
The excess of cash flows of a loan, or pool of loans, expected to be collected over the estimated fair value is referred to as the "accretable yield" and is recognized into interest income over the estimated remaining life of the loan, or pool of loans, on a level-yield basis. The difference between the contractually required payments of a loan, or pool of loans, and the cash flows expected to be collected at acquisition, considering the impact of prepayments and estimates of future credit losses expected to be incurred over the life of the loan, or pool of loans, is referred to as the "nonaccretable difference."
The Corporation is required to quarterly evaluate its estimates of cash flows expected to be collected from acquired loans. These evaluations require the continued usage of key assumptions and estimates, similar to the initial estimate of fair value. Given the current economic environment, the Corporation must apply judgment to develop its estimates of cash flows for acquired loans given the impact of changes in property values, default rates, loss severities and prepayment speeds. Decreases in the estimates of expected cash flows will generally result in a charge to the provision for loan losses and a resulting increase to the allowance for loan losses. Increases in the estimates of expected cash flows will generally result in adjustments to the accretable yield, which will increase amounts recognized in interest income in subsequent periods. Dispositions of acquired loans, which may include sales of loans to third parties, receipt of payments in full or in part by the borrower and foreclosure of the collateral, result in removal of the loan from the acquired loan portfolio at its carrying amount. As a result of the significant amount of judgment involved in estimating future cash flows expected to be collected for acquired loans, the adequacy of the allowance for loan losses could be significantly impacted by changes in expected cash flows resulting from changes in credit quality of acquired loans.
Acquired loans that were classified as nonperforming loans prior to being acquired and acquired loans that are not performing in accordance with contractual terms subsequent to acquisition are not classified as nonperforming loans subsequent to acquisition because the loans are recorded in pools at net realizable value based on the principal and interest the Corporation expects to collect on such loans. Judgment is required to estimate the timing and amount of cash flows expected to be collected when the loans are not performing in accordance with the original contractual terms.

27

Pension Plan Accounting
The Corporation has a defined benefit pension plan for certain salaried employees. Effective June 30, 2006, benefits under the defined benefit pension plan were frozen for approximately two-thirds of the Corporation's salaried employees as of that date. Pension benefits continued unchanged for the remaining salaried employees. At December 31, 2015, 161 employees, or 7.6% of total employees on a full-time equivalent basis, were earning pension benefits under the defined benefit pension plan. The Corporation's pension benefit obligations and related costs are calculated using actuarial concepts and measurements. Benefits under the plan are based on years of vested service, age and amount of compensation. Assumptions are made concerning future events that will determine the amount and timing of required benefit payments, funding requirements and pension expense.
The key actuarial assumptions used in the pension plan are the discount rate and long-term rate of return on plan assets. These assumptions have a significant effect on the amounts reported for net periodic pension expense, as well as the respective benefit obligation amounts. The Corporation evaluates these critical assumptions annually. At December 31, 2015, 2014 and 2013, the Corporation calculated a discount rate of 4.55%, 4.15% and 5.00%, respectively, for the pension plan using the results from a bond matching technique, which matched the future estimated annual benefit payments of the pension plan against a portfolio of bonds of Aa quality to determine the discount rate.
The assumed long-term rate of return on pension plan assets represents an estimate of long-term returns on an investment portfolio consisting primarily of equity and fixed income investments. When determining the expected long-term return on pension plan assets, the Corporation considers long-term rates of return on the asset classes in which the Corporation expects the pension funds to be invested. The expected long-term rate of return is based on both historical and forecasted returns of the overall stock and bond markets and the actual portfolio. The difference between the expected return and the actual return on pension plan assets during the year is either an asset gain or loss, which is deferred and amortized over future periods when determining net periodic pension expense. The Corporation's projection of the long-term return on pension plan assets was 7.0% in 2015, 2014 and 2013, while the actual return on pension plan assets was 0.7%, 4.7% and 18.2% in 2015, 2014 and 2013, respectively.
Other assumptions made in the pension plan calculations involve employee demographic factors, such as retirement patterns, mortality, turnover and the rate of compensation increase.
The key actuarial assumptions that will be used to calculate pension expense in 2016 for the defined benefit pension plan are a discount rate of 4.55%, a long-term rate of return on pension plan assets of 6.75% and a rate of compensation increase of 3.5%. The Corporation is expected to have pension expense of $0.1 million in 2016, compared to $1.6 million in 2015. The expected decrease in pension expense in 2016, as compared to 2015, is primarily attributable to an increase in the discount rate used to measure the present value of expected future benefit payments and an increase in retirement age assumptions for employees. In 2016, a decrease in the discount rate of 50 basis points and 100 basis points is estimated to increase pension expense by $0.6 million and $1.2 million, respectively, while an increase of 50 basis points and 100 basis points is estimated to decrease pension expense by approximately the same amounts.
There are uncertainties associated with the underlying key actuarial assumptions, and the potential exists for significant, and possibly material, impacts on either or both the results of operations and cash flows (e.g., additional pension expense and/or additional pension plan funding, whether expected or required) from changes in the key actuarial assumptions. If the Corporation were to determine that more conservative assumptions are necessary, pension expense would increase and have a negative impact on results of operations in the period in which the increase occurs.
The Corporation accounts for its defined benefit pension and other postretirement plans in accordance with ASC Topic 715, Compensation-Retirement Benefits, which requires companies to recognize the over- or under-funded status of a plan as an asset or liability as measured by the difference between the fair value of the plan assets and the projected benefit obligation and requires any unrecognized prior service costs and actuarial gains and losses to be recognized as a component of accumulated other comprehensive income (loss). The impact of pension plan accounting on the statements of financial position at December 31, 2015 and 2014 is further discussed in Note 16 to the consolidated financial statements.

28

Income and Other Taxes
The Corporation is subject to the income and other tax laws of the United States, the State of Michigan and other states where nexus has been created. These laws are complex and are subject to different interpretations by the taxpayer and the various taxing authorities. In determining the provisions for income and other taxes, management must make judgments and estimates about the application of these inherently complex laws, related regulations and case law. In the process of preparing the Corporation's tax returns, management attempts to make reasonable interpretations of enacted tax laws. These interpretations are subject to challenge by the tax authorities upon audit or to reinterpretation based on management's ongoing assessment of facts and evolving case law.
The Corporation and its subsidiaries file a consolidated federal income tax return. The provision for federal income taxes is based on income and expenses, as reported in the consolidated financial statements, rather than amounts reported on the Corporation's federal income tax return. When income and expenses are recognized in different periods for tax purposes than for book purposes, applicable deferred tax assets and liabilities are recognized for the future tax consequences attributable to the differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized as income or expense in the period that includes the enactment date.
On a quarterly basis, management assesses the reasonableness of its effective federal tax rate based upon its estimate of taxable income and the applicable taxes expected for the full year, including the impact of any discrete items that have occurred. Deferred tax assets and liabilities are reassessed on a quarterly basis, including the need for a valuation allowance for deferred tax assets. The need for reserves for uncertain tax positions is reviewed quarterly based upon developments in tax law and the status of examinations or audits. As of December 31, 2015 and 2014, there were no federal income tax reserves recorded for uncertain tax positions.
Goodwill
Goodwill represents the excess of the purchase price of the Corporation's acquisition of various banks and bank branches over the fair value of the net assets acquired in the various acquisitions. The Corporation's goodwill totaled $287.4 million at December 31, 2015, compared to $180.1 million at December 31, 2014. The increase in goodwill during 2015 was due to the Lake Michigan and Monarch transactions. Goodwill is not amortized, but rather is tested by management annually for impairment, or more frequently if triggering events occur and indicate potential impairment, in accordance with ASC Topic 350-20, Goodwill (ASC 350-20). ASC 350-20 allows an entity to assess qualitative factors to determine whether it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount. ASC 350-20 also allows an entity to bypass the qualitative assessment approach and determine if goodwill is impaired utilizing a quantitative assessment approach. The Corporation performed its 2015 annual goodwill impairment assessment as of October 31, 2015 utilizing the qualitative assessment approach.
In evaluating whether it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount, the Corporation assesses relevant events and circumstances, including macroeconomic conditions, industry and market considerations, overall financial performance, changes in the composition or carrying amount of assets and liabilities, the market price of the Corporation's common stock, and other relevant factors. Based on the qualitative assessment performed, the Corporation determined that no goodwill impairment was evident as of the October 31, 2015 assessment date. The Corporation also determined that no triggering events occurred that indicated potential impairment of goodwill from the most recent assessment date through December 31, 2015 and that the Corporation's goodwill was not impaired at December 31, 2015. However, the Corporation could incur impairment charges related to goodwill in the future due to changes in financial results or other matters that could affect the fair value of the Corporation's reporting units.
Fair Value Measurements
The Corporation determines the fair value of its assets and liabilities in accordance with ASC Topic 820, Fair Value Measurements and Disclosures (ASC 820). ASC 820 establishes a standard framework for measuring and disclosing fair value under GAAP. Estimates, assumptions and judgments may be necessary when assets and liabilities are required to be recorded at fair value or when a decline in the value of an asset not carried at fair value on the financial statements warrants an impairment write-down or a valuation reserve to be established. Carrying assets and liabilities at fair value inherently results in more financial statement volatility. The fair values and the information used to record valuation adjustments for certain assets and liabilities are based either on quoted market prices or are provided by third-party sources, when available. When third-party information is not available, valuation adjustments are estimated by management primarily through the use of internal discounted cash flow analyses, and to the extent available, observable market-based inputs.
A number of valuation techniques are used to determine the fair value of assets and liabilities in the Corporation's financial statements. The valuation techniques include quoted market prices for investment securities, appraisals of real estate from independent licensed appraisers and other valuation techniques. Fair value measurements for assets and liabilities where limited

29

or no observable market data exists are based primarily upon estimates, and are often calculated based on the economic and competitive environment, the characteristics of the asset or liability and other factors. Therefore, the valuation results cannot be determined with precision and may not be realized in an actual sale or immediate settlement of the asset or liability. Additionally, there are inherent weaknesses in any calculation technique, and changes in the underlying assumptions used, including discount rates and estimates of future cash flows, could significantly affect the results of current or future values. Significant changes in the aggregate fair value of assets and liabilities required to be measured at fair value or for impairment are recognized in the income statement under the framework established by GAAP. See Note 13 to the Corporation's consolidated financial statements for more information on fair value measurements.
Accounting Standards Updates
See Note 1 to the consolidated financial statements included in this report for details of accounting pronouncements adopted by the Corporation during 2015 and recently issued and pending accounting pronouncements and their potential impact on the Corporation's financial statements.
FINANCIAL HIGHLIGHTS
The following discussion and analysis is intended to cover significant factors affecting the Corporation's consolidated statements of financial position and income included in this report. It is designed to provide a more comprehensive review of the consolidated operating results and financial position of the Corporation than could be obtained from an examination of the financial statements alone.
NON-GAAP FINANCIAL MEASURES
This report contains references to financial measures that are not defined in GAAP. Such non-GAAP financial measures include the Corporation's tangible equity to tangible assets ratio, presentation of net interest income and net interest margin on a fully taxable equivalent (FTE) basis and information presented excluding nonrecurring acquisition-related expenses, including net income, diluted earnings per share, return on average assets, return on average shareholders' equity and operating expenses. These non-GAAP financial measures have been included as the Corporation believes they are helpful for investors to analyze and evaluate the Corporation's financial performance. Limitations associated with non-GAAP financial measures include the risk that persons might disagree as to the appropriateness of items comprising these measures and that different companies might calculate these measures differently. These non-GAAP disclosures should not be considered an alternative to the Corporation's GAAP results. A reconciliation of the Corporation's non-GAAP financial measures follows:

NET INCOME
Net income in 2015 was $86.8 million, or $2.39 per diluted share, compared to net income in 2014 of $62.1 million, or $1.97 per diluted share and net income in 2013 of $56.8 million, or $2.00 per diluted share. Net income included nonrecurring acquisition-related expenses of $7.8 million in 2015 and $6.4 million in 2014. Excluding nonrecurring acquisition-related expenses, net income in 2015 was $92.3 million, or $2.54 per diluted share, compared to net income in 2014 of $66.7 million, or $2.11 per diluted share. Excluding nonrecurring acquisition-related expenses, the increase in net income in 2015, compared to 2014, was primarily attributable to incremental earnings resulting from the Lake Michigan, Monarch and Northwestern acquisitions, while the increase in net income in 2014, compared to 2013, was primarily attributable to an increase in net interest income, a decrease in the provision for loan losses and the impact of the acquisition of Northwestern, which were partially offset by an increase in operating expenses.
The Corporation's return on average assets was 1.02% in 2015, 0.96% in 2014 and 0.95% in 2013 and the Corporation's return on average shareholders' equity was 9.4% in 2015, 8.2% in 2014 and 9.1% in 2013. Excluding nonrecurring acquisition-related expenses, the Corporation's return on average assets was 1.09% in 2015 and 1.03% in 2014 and the Corporation's return on average shareholders' equity was 10.0% in 2015 and 8.8% in 2014.
ASSETS
Total assets were $9.19 billion at December 31, 2015, an increase of $1.87 billion, or 25%, from total assets at December 31, 2014 of $7.32 billion. The increase in total assets during 2015 was primarily attributable to the Lake Michigan and Monarch acquisitions, which increased the Corporation's total assets by $1.47 billion as of the respective acquisition dates. The increase in total assets was also partially attributable to an increase in customer deposits that were utilized to partially fund loan growth.
Average assets were $8.48 billion during 2015, an increase of $2.01 billion, or 31%, from average assets of $6.47 billion during 2014. Average assets during 2014 increased $509 million, or 8.5%, from average assets of $5.96 billion during 2013. The increase in average assets during 2015, as compared to 2014, was attributable to a combination of the $1.47 billion of assets acquired in the Lake Michigan and Monarch transactions and a $382 million organic increase in customer deposits that were utilized to partially fund loan growth. The increase in average assets during 2014, as compared to 2013, was largely attributable to an increase in customer deposits that were utilized to partially fund loan growth, although also attributable to the $794 million of deposits acquired in the Northwestern transaction. Excluding the $794 million of deposits acquired in the Northwestern transaction on October 31, 2014, average customer deposits were approximately $250 million higher in 2014 than 2013.

(1)
Yields are weighted by amount and time to contractual maturity, are on a taxable equivalent basis using a 35% federal income tax rate and are based on carrying value. Yields disclosed are actual yields based on carrying value at December 31, 2015. Approximately 10% of the Corporation's investment securities at December 31, 2015 were variable-rate financial instruments.
(2)
Residential mortgage-backed securities, collateralized mortgage obligations and certain government sponsored agencies are based on scheduled principal maturity. All other investment securities are based on final contractual maturity.
(3)
The aggregate book value of securities issued by any single issuer, other than the U.S. government and government sponsored agencies, did not exceed 10% of the Corporation's shareholders' equity.
The Corporation utilizes third-party pricing services to obtain market value prices for its investment securities portfolio. On a quarterly basis, the Corporation validates the reasonableness of prices received from the third-party pricing services through independent price verification on a sample of investment securities in the portfolio, data integrity validation based upon comparison of current market prices to prior period market prices and analysis of overall expectations of movement in market prices based upon the changes in the related yield curves and other market factors. On a quarterly basis, the Corporation reviews the pricing methodology of the third-party pricing vendors and the results of the vendors' internal control assessments to ensure the integrity of the process that the vendor uses to develop market pricing for the Corporation's investment securities portfolio.
The carrying value of investment securities totaled $1.06 billion at December 31, 2015, compared to $1.07 billion at December 31, 2014. The Corporation acquired $67 million of investment securities in the Lake Michigan transaction. In addition, the Corporation utilized maturing available-for-sale investment securities during 2015 to significantly increase its holdings in state and political subdivisions and to partially fund loan growth. Investment securities increased $107 million, or 11%, during 2014, with the increase attributable to $230 million of investment securities acquired in the Northwestern transaction as of the acquisition date, comprised primarily of debt instruments sponsored or backed by U.S. government agencies, which were partially offset by the Corporation utilizing maturing investment securities in 2014 to partially fund loan growth. The Corporation increased its holdings in state and political subdivisions in 2015 and 2014, as it was able to identify municipal investments within its operating markets that both met its investment objectives and provided an attractive yield when compared to other investment securities options.
The Corporation's investment securities portfolio as of December 31, 2015 had a weighted average life of approximately 3.3 years and an effective duration of approximately 2.2 years.

At December 31, 2015, the Corporation's investment securities portfolio consisted of: U.S. Treasury securities, comprised of fixed-rate government debt instruments issued by the U.S. Department of Treasury, totaling $5.8 million; government sponsored agency (GSA) debt obligations, comprised primarily of fixed-rate instruments backed by Federal Home Loan Banks, Federal Farm Credit Banks and Student Loan Marketing Corporation, totaling $195.0 million; state and political subdivisions debt obligations, comprised primarily of general debt obligations of issuers primarily located in the State of Michigan, totaling $524.6 million; residential mortgage-backed securities (MBSs), comprised primarily of fixed-rate instruments backed by a U.S. government agency (Government National Mortgage Association) or government sponsored enterprises (Federal Home Loan Mortgage Corporation and Federal National Mortgage Association), totaling $187.8 million; collaterized mortgage obligations (CMOs), comprised of approximately 75% fixed-rate and 25% variable-rate instruments backed by the same U.S. government agency and government sponsored enterprises as the residential MBSs, with average maturities of less than three years, totaling $132.2 million; corporate bonds, comprised primarily of debt obligations of large U.S. global financial organizations, totaling $14.6 million; preferred stock and trust preferred securities (TRUPs), comprised of preferred stock debt instruments of two large regional/national banks and variable-rate TRUPs from both a publicly-traded bank holding company and a small non-public bank holding company, totaling $3.7 million. Fixed-rate instruments comprised approximately 90% of the Corporation's investment securities portfolio at December 31, 2015.
The Corporation records all investment securities in accordance with ASC Topic 320, Investments-Debt and Equity Securities (ASC 320), under which the Corporation is required to assess equity and debt securities that have fair values below their amortized cost basis to determine whether the decline (impairment) is other-than-temporary. An assessment is performed quarterly by the Corporation to determine whether unrealized losses in its investment securities portfolio are temporary or other-than-temporary by considering all reasonably available information. The Corporation reviews factors such as financial statements, credit ratings, news releases and other pertinent information of the underlying issuer or company to make its determination. In assessing whether a decline is other-than-temporary, management considers, among other things (i) the length of time and the extent to which the fair value has been less than amortized cost, (ii) the financial condition and near-term prospects of the issuer, (iii) the potential for impairments in an entire industry or sub-sector and (iv) the potential for impairments in certain economically depressed geographical locations.
The Corporation's investment securities portfolio, with a carrying value of $1.06 billion at December 31, 2015, had gross impairment of $9.1 million at that date. Management believed that the unrealized losses on investment securities were temporary in nature and due primarily to changes in interest rates on the investment securities and market illiquidity, and not as a result of credit-related issues. Accordingly, the Corporation believed the impairment in its investment securities portfolio at December 31, 2015 was temporary in nature, and therefore, no impairment loss was recognized in the Corporation's consolidated statement of income in 2015. However, other-than-temporary impairment (OTTI) may occur in the future as a result of material declines in the fair value of investment securities resulting from market, credit, economic or other conditions. A further discussion of the assessment of potential impairment and the Corporation's process that resulted in the conclusion that the impairment was temporary in nature follows.

33

At December 31, 2015, the gross impairment in the Corporation's investment securities portfolio of $9.1 million was comprised as follows: GSA securities, residential MBSs and CMOs, combined, of $4.2 million, state and political subdivisions securities of $4.5 million, corporate bonds of $0.2 million and TRUPs of $0.2 million. The amortized costs and fair values of investment securities are disclosed in Note 3 to the consolidated financial statements.
GSA securities, residential MBSs and CMOs, included in the available-for-sale investment securities portfolio, had a combined amortized cost of $518 million and gross impairment of $4.2 million at December 31, 2015. Virtually all of the impaired investment securities in these categories are backed by the full faith and credit of the U.S. government or a guarantee of a U.S. government agency or government sponsored enterprise. The Corporation determined that the impairment on these investment securities was attributable to current market interest rates being higher than the yields being earned on these investment securities. The Corporation concluded that the impairment of its GSA securities, residential MBSs and CMOs was temporary in nature at December 31, 2015.
State and political subdivisions securities, included in both the available-for-sale and held-to-maturity investment securities portfolios, had an amortized cost of $524 million and gross impairment of $4.5 million at December 31, 2015. The Corporation's state and political subdivisions securities are almost entirely from issuers primarily located in the State of Michigan and of which approximately 80% are general obligations of the issuer, meaning that repayment of these obligations is funded by general tax collections of the issuer. The gross impairment was attributable to impaired state and political subdivisions securities with an amortized cost of $268 million that generally mature beyond 2017. It was the Corporation's assessment that the impairment on these investment securities was attributable to current market interest rates being slightly higher than the yield on these investment securities, illiquidity in the market for a portion of these investment securities caused by the market's perception of the Michigan economy, and illiquidity in the market due to the nature of a portion of these investment securities. The Corporation concluded that the impairment of its state and political subdivisions securities was temporary in nature at December 31, 2015.
At December 31, 2015, the Corporation held one TRUP in the held-to-maturity investment securities portfolio, with an amortized cost of $0.5 million and gross impairment of $0.2 million. This TRUP represents a 10% interest in the TRUP of a well-capitalized non-public bank holding company in Michigan. The principal of $0.5 million of this TRUP matures in 2033, with interest payments due quarterly. All scheduled interest payments on this TRUP have been made on a timely basis. The Corporation determined that the impairment on this TRUP was attributable to a lack of liquidity for issuances of this size. The Corporation concluded that the impairment was temporary in nature at December 31, 2015.
At December 31, 2015, the Corporation expected to fully recover the entire amortized cost basis of each impaired investment security in its investment securities portfolio at that date. Furthermore, at December 31, 2015, the Corporation did not have the intent to sell any of its impaired investment securities and believed that it was more-likely-than-not that the Corporation would not have to sell any of its impaired investment securities before a full recovery of amortized cost. However, there can be no assurance that OTTI losses will not be recognized on any investment security in the future.
LOANS
The Corporation's loan portfolio is comprised of commercial, commercial real estate, real estate construction and land development loans, referred to as the Corporation's commercial loan portfolio, and residential mortgage, consumer installment and home equity loans, referred to as the Corporation's consumer loan portfolio. At December 31, 2015, the Corporation's loan portfolio was $7.27 billion and consisted of loans in the commercial loan portfolio totaling $4.25 billion, or 58% of total loans, and loans in the consumer loan portfolio totaling $3.02 billion, or 42% of total loans. Loans at fixed interest rates comprised 74% of the Corporation's total loan portfolio at December 31, 2015, compared to 77% at December 31, 2014 and 76% at December 31, 2013.
Chemical Bank is a full-service commercial bank and the acceptance and management of credit risk is an integral part of the Corporation's business. The Corporation maintains loan policies and credit underwriting standards as part of the process of managing credit risk. These standards include making loans generally only within the Corporation's market areas. The Corporation's lending markets generally consist of communities across the lower peninsula of Michigan, except for the southeastern portion of Michigan. The Corporation has no foreign loans or any loans to finance highly leveraged transactions. The Corporation's lending philosophy is implemented through strong administrative and reporting controls. The Corporation maintains a centralized independent loan review function that monitors the approval process and ongoing asset quality of the loan portfolio.
Total loans were $7.27 billion at December 31, 2015, an increase of $1.58 billion, or 28%, from total loans of $5.69 billion at December 31, 2014. The increase in total loans during 2015 was attributable to $1.11 billion of loans acquired in the Lake Michigan and Monarch acquisitions and organic loan growth of $476 million, or 8.4%. Total loans increased $1.04 billion, or 22%, during 2014, from total loans of $4.65 billion at December 31, 2013. The increase in total loans during 2014 was attributable to organic loan growth of $565 million, or 12%, and $475 million of loans acquired in the Northwestern transaction. Organic loan growth during 2015 and 2014 generally occurred across all major loan categories and across all of the Corporation's banking markets and was attributable to a combination of improving economic conditions and higher loan demand, as well as the Corporation increasing its market share in both its commercial and consumer loan portfolios.

A discussion of the Corporation's loan portfolio by category follows.
Commercial Loan Portfolio
The Corporation's commercial loan portfolio is comprised of commercial loans, commercial real estate loans, real estate construction loans and land development loans. The Corporation's commercial loan portfolio is well diversified across business lines and has no concentration in any one industry. The commercial loan portfolio of $4.25 billion at December 31, 2015 included 126 loan relationships of $5.0 million or greater. These 126 loan relationships totaled $1.27 billion, which represented 30% of the commercial loan portfolio at December 31, 2015 and included 42 loan relationships that had outstanding balances of $10 million or higher, totaling $689 million, or 16% of the commercial loan portfolio, at that date. The Corporation had 10 loan relationships that had outstanding balances of $20 million or higher, totaling $255 million, or 6.0% of the commercial loan portfolio, at December 31, 2015. The Corporation had 13 loan relationships at December 31, 2015 with loan balances greater than $5.0 million and less than $10 million, totaling $110 million, that had unfunded credit commitments totaling $58 million that, if advanced, could result in a loan relationship of $10 million or more.

35

Table 4 presents the maturity distribution of the Corporation's $4.25 billion commercial loan portfolio at December 31, 2015. The percentage of these loans maturing within one year was 26% at December 31, 2015, while the percentage of these loans maturing beyond five years remained low at 18% at December 31, 2015. At December 31, 2015, loans in the commercial loan portfolio with maturities beyond one year totaled $3.16 billion, with 73% of these loans at fixed interest rates.

Commercial loans consist of loans and lines of credit to varying types of businesses, including municipalities, school districts and nonprofit organizations, for the purpose of supporting working capital and operational needs and term financing of equipment. Repayment of such loans is generally provided through operating cash flows of the customer. Commercial loans are generally secured with inventory, accounts receivable, equipment, personal guarantees of the owner or other sources of repayment, although the Corporation may also obtain real estate as collateral.
Commercial loans were $1.91 billion at December 31, 2015, an increase of $551 million, or 41%, from commercial loans of $1.35 billion at December 31, 2014. Commercial loans grew organically by $230 million, or 17%, during 2015, with the remainder of the growth attributable to the two acquisition transactions completed during the year. Commercial loans increased $179 million, or 15%, during 2014 from commercial loans of $1.18 billion at December 31, 2013. Commercial loans grew organically by $133 million, or 11%, during 2014, with the remainder of the growth attributable to the Northwestern transaction. Commercial loans represented 26.2% of the Corporation's loan portfolio at December 31, 2015, compared to 23.8% and 25.3% at December 31, 2014 and 2013, respectively.
Commercial real estate loans include loans that are secured by real estate occupied by the borrower for ongoing operations, non-owner occupied real estate leased to one or more tenants and vacant land that has been acquired for investment or future land development. Commercial real estate loans were $2.11 billion at December 31, 2015, an increase of $555 million, or 36%, from commercial real estate loans of $1.56 billion at December 31, 2014. The growth in commercial real estate loans during 2015 was attributable to the two acquisitions completed during the year. Loans secured by owner occupied properties, non-owner occupied properties and vacant land comprised 51%, 46% and 3%, respectively, of the Corporation's commercial real estate loans outstanding at December 31, 2015. Commercial real estate loans increased $325 million, or 26%, during 2014 from commercial real estate loans of $1.23 billion at December 31, 2013. Commercial real estate loans grew organically by $103 million, or 8.3%, during 2014, with the remainder of growth due to the Northwestern transaction. Commercial real estate loans represented 29.0% of the Corporation's loan portfolio at December 31, 2015, compared to 27.4% and 26.5% at December 31, 2014 and 2013, respectively.
Commercial and commercial real estate lending is generally considered to involve a higher degree of risk than residential mortgage, consumer installment and home equity lending as they typically involve larger loan balances concentrated in a single borrower. In addition, the payment experience on loans secured by income-producing properties and vacant land loans is typically dependent on the success of the operation of the related project and is typically affected by adverse conditions in the real estate market and in the economy. The Corporation generally attempts to mitigate the risks associated with commercial and commercial real estate lending by, among other things, lending primarily in its market areas, lending across industry lines, not developing a concentration in any one line of business and using prudent loan-to-value ratios in the underwriting process. It is management's belief that the Corporation's commercial and commercial real estate loan portfolios are generally well-secured.

36

Real estate construction loans are primarily originated for construction of commercial properties and often convert to a commercial real estate loan at the completion of the construction period. Real estate construction loans were $210 million at December 31, 2015, an increase of $57 million, or 38%, from real estate construction loans of $153 million at December 31, 2014. Real estate construction loans increased $63 million, or 70%, during 2014 from real estate construction loans of $90 million at December 31, 2013. The increase in real estate construction loans during both 2015 and 2014 was largely attributable to advances on new and existing commercial construction projects, representing a combination of owner and non-owner occupied commercial properties. Real estate construction loans represented 2.9% of the Corporation's loan portfolio at December 31, 2015, compared to 2.7% and 1.9% at December 31, 2014 and 2013, respectively.
Land development loans include loans made to developers for the purpose of infrastructure improvements to vacant land to create finished marketable residential and commercial lots/land. A majority of the Corporation's land development loans consist of loans to develop residential real estate. Land development loans are generally originated as interest only with the intention that the loan principal balance will be repaid through the sale of finished properties by the developers within twelve months of the completion date. Land development loans were $21.8 million at December 31, 2015, an increase of $3.1 million, or 16.5%, from land development loans of $18.8 million at December 31, 2014. Land development loans decreased $1.3 million, or 6.6%, during 2014 from land development loans of $20.1 million at December 31, 2013. Land development loans represented 0.3% of the Corporation's loan portfolio at both December 31, 2015 and December 31, 2014, compared to 0.4% at December 31, 2013.
Real estate construction and land development lending involves a higher degree of risk than commercial real estate lending and residential mortgage lending because of the uncertainties of construction, including the possibility of costs exceeding the initial estimates, the need to obtain a tenant or purchaser of the property if it will not be owner-occupied or the need to sell developed properties. The Corporation generally attempts to mitigate the risks associated with real estate construction and land development lending by, among other things, lending primarily in its market areas, using prudent underwriting guidelines and closely monitoring the construction process. At December 31, 2015, $1.7 million, or 8%, of the Corporation's $21.8 million of land development loans were impaired, whereby the Corporation determined it was probable that the full amount of principal and interest would not be collected on these loans in accordance with their original contractual terms. At December 31, 2014, $1.9 million, or 10% of the Corporation's $18.8 million of land development loans were impaired.
Consumer Loan Portfolio
The Corporation's consumer loan portfolio is comprised of residential mortgage loans, consumer installment loans and home equity loans and lines of credit.
Residential mortgage loans consist primarily of one- to four-family residential loans with fixed interest rates of fifteen years or less, with amortization periods generally from fifteen to thirty years. The loan-to-value ratio at the time of origination is generally 80% or less. Loans with more than an 80% loan-to-value ratio generally require private mortgage insurance. At December 31, 2015, approximately 70% of the Corporation's residential mortgage loans had an original loan-to-value ratio of 80% or less.
Residential mortgage loans were $1.43 billion at December 31, 2015, an increase of $319 million, or 29%, from residential mortgage loans of $1.11 billion at December 31, 2014. Residential mortgage loans grew organically by $175 million, or 16%, during 2015, with the remainder of the growth attributable to the two acquisition transactions completed during the year. Residential mortgage loans increased $150 million, or 16%, during 2014 from residential mortgage loans of $960.4 million at December 31, 2013. Residential mortgage loans grew organically by $44 million, or 4.5%, during 2014, with the remainder of the growth attributable to the Northwestern transaction. Residential mortgage loans had historically involved the least amount of credit risk in the Corporation's loan portfolio, although the risk on these loans increased during the most recent economic downturn when the unemployment rate increased and real estate property values declined in the State of Michigan. Residential mortgage loans also include loans to consumers for the construction of single family residences that are secured by these properties. Residential mortgage construction loans to consumers were $62.2 million at December 31, 2015, compared to $42.5 million at December 31, 2014 and $37.9 million at December 31, 2013. Residential mortgage loans represented 19.7% of the Corporation's loan portfolio at December 31, 2015, compared to 19.5% and 20.7% at December 31, 2014 and 2013, respectively. The Corporation had residential mortgage loans with maturities beyond five years and that were at fixed interest rates totaling $379 million at December 31, 2015, compared to $306 million at December 31, 2014.
The Corporation's consumer installment loans consist of relatively small loan amounts to consumers to finance personal items (primarily automobiles, recreational vehicles and marine vehicles) and are comprised primarily of indirect loans purchased from dealerships. Consumer installment loans were $877 million at December 31, 2015, an increase of $48 million, or 5.8%, from consumer installment loans of $829.6 million at December 31, 2014. Consumer installment loans increased $185 million, or 29%, during 2014 from consumer installment loans of $645 million at December 31, 2013. The increases in the Corporation's consumer installment loans during 2015 and 2014 were primarily attributable to organic growth. At December 31, 2015, collateral securing consumer installment loans was comprised approximately as follows: automobiles - 58%; recreational vehicles - 25%; marine vehicles - 12%; other collateral - 4%; and unsecured - 1%. Consumer installment loans represented 12.1% of the Corporation's loan portfolio at December 31, 2015, compared to 14.6% and 13.9% at December 31, 2014 and 2013, respectively.

37

The Corporation's home equity loans, including home equity lines of credit, are comprised of loans to consumers who utilize equity in their personal residence, including junior lien mortgages, as collateral to secure the loan or line of credit. Home equity loans were $714 million at December 31, 2015, an increase of $50 million, or 7.5%, from home equity loans of $664 million at December 31, 2014. The growth in home equity loans during 2015 was attributable to the two acquisitions completed during the year. Home equity loans increased $141 million, or 27%, during 2014 from home equity loans of $524 million at December 31, 2013. Home equity loans grew organically by $61 million, or 12%, during 2014, with the remainder of the growth attributable to the Northwestern transaction. At December 31, 2015, approximately 60% of the Corporation's home equity loans were first lien mortgages and 40% were junior lien mortgages. Home equity loans represented 9.8% of the Corporation's loan portfolio at December 31, 2015, compared to 11.7% and 11.3% at December 31, 2014 and 2013, respectively. Home equity lines of credit comprised $278 million, or 39%, of the Corporation's home equity loans at December 31, 2015, compared to $231 million, or 35%, of home equity loans at December 31, 2014. The majority of the Corporation's home equity lines of credit are comprised of loans with payments of interest only and original maturities of up to ten years. These home equity lines of credit include junior lien mortgages whereby the first lien mortgage is held by a nonaffiliated financial institution.
Consumer installment and home equity loans generally have shorter terms than residential mortgage loans, but generally involve more credit risk than residential mortgage lending because of the type and nature of the collateral. The Corporation experienced decreases in losses on consumer installment and home equity loans in 2015, with net loan losses totaling 19 basis points of average consumer installment and home equity loans during 2015, compared to 32 basis points of average consumer installment and home equity loans in 2014. Consumer installment and home equity loans are spread across many individual borrowers, which minimizes the risk per loan transaction. The Corporation originates consumer installment and home equity loans utilizing a computer-based credit scoring analysis to supplement the underwriting process. Consumer installment and home equity lending collections are dependent on the borrowers' continuing financial stability and are more likely to be affected by adverse personal situations. Collateral values on properties securing consumer installment and home equity loans are negatively impacted by many factors, including the physical condition of the collateral and property values, although losses on consumer installment and home equity loans are often more significantly impacted by the unemployment rate and other economic conditions. The unemployment rate in the State of Michigan was 5.1% at December 31, 2015, compared to 6.3% at December 31, 2014, and slightly higher than the national average of 5.0% at December 31, 2015.
ASSET QUALITY
Nonperforming Assets
Nonperforming assets include nonperforming loans, which consist of originated loans for which the accrual of interest has been discontinued (nonaccrual loans), originated loans that are past due as to principal or interest by 90 days or more and still accruing interest and nonperforming loans that have been modified under troubled debt restructurings (TDRs). Nonperforming assets also include assets obtained through foreclosures and repossessions. The Corporation transfers an originated loan that is 90 days or more past due to nonaccrual status (except for loans that are secured by residential real estate, which are transferred at 120 days past due), unless it believes the loan is both well-secured and in the process of collection. For loans classified as nonaccrual, including those with modifications, the Corporation does not expect to receive all principal and interest payments, and therefore, any payments are recognized as principal reductions when received. Conversely, the Corporation expects to receive all principal and interest payments on loans that meet the definition of nonperforming TDR status. TDRs continue to be reported as nonperforming loans until a six-month payment history of principal and interest payments is sustained in accordance with the terms of the loan modification, at which time the loan is no longer considered a nonperforming asset and the Corporation moves the loan to a performing TDR status.
Nonperforming assets were $93.8 million at December 31, 2015, an increase of $8.4 million, or 9.9%, from $85.4 million at December 31, 2014. The increase in nonperforming assets during 2015 was primarily due to a $10 million commercial loan relationship that was downgraded to nonaccrual status during the year. This commercial loan relationship was the only commercial loan relationship of the Corporation that was in nonperforming status and exceeded $5.0 million at December 31, 2015. Nonperforming assets decreased $6.4 million, or 6.9%, during 2014 from $91.8 million at December 31, 2013. Nonperforming assets represented 1.02%, 1.17% and 1.48% of total assets at December 31, 2015, 2014 and 2013, respectively. The Corporation's nonperforming assets are not concentrated in any one industry or any one geographical area within Michigan. While the economic climate in Michigan continues to improve, management continues to evaluate and, when appropriate, obtain new appraisals or discount appraised values of existing appraisals to compute net realizable values of nonperforming real estate secured loans and other real estate properties.
Nonperforming assets at December 31, 2015 and 2014 did not include impaired acquired loans totaling $12.8 million and $19.9 million, respectively, even though these loans were not performing in accordance with their original contractual terms. Acquired loans that are not performing in accordance with contractual terms are not reported as nonperforming loans because these loans are recorded in pools at their net realizable value based on the principal and interest the Corporation expects to collect on these

38

loan pools. Acquired loans not performing in accordance with the loan's original contractual terms are included in the Corporation's impaired loan schedule in Note 4 to the consolidated financial statements.
Table 5 provides a five-year history of nonperforming assets, including the composition of nonperforming loans by major loan category.

There was no interest income recognized on nonaccrual loans in 2015 while they were in nonaccrual status. During 2015, the Corporation received and recognized $0.9 million of interest income on these loans while they were in an accruing status. Additional interest income of $3.2 million would have been recorded in 2015 on nonaccrual loans existing at December 31, 2015 had they been current in accordance with their original terms.
(2)
Interest income of $3.9 million was recorded in 2015 on performing and nonperforming TDRs. The interest income recognized on residential mortgage TDRs may include accretion of an identified impairment at the time of modification, which is attributable to a temporary reduction in the borrower's interest rate.
(3)
Includes property acquired through foreclosure and by acceptance of a deed in lieu of foreclosure and other property held for sale, including properties acquired as a result of acquisition transactions.
The Corporation's nonaccrual loans that meet the definition of a TDR (nonaccrual TDR) totaled $35.9 million, $37.2 million, $37.3 million, $47.5 million and $41.8 million at December 31, 2015, 2014, 2013, 2012 and 2011, respectively. These loans have been modified by providing the borrower a financial concession that is intended to improve the Corporation's probability of collection of the amounts due.

Total nonperforming loans were $83.9 million at December 31, 2015, an increase of $12.7 million, or 17.8%, compared to $71.2 million at December 31, 2014. The increase in nonperforming loans during 2015 was primarily due to a $10 million commercial loan relationship being downgraded to nonaccrual status during the year. As of December 31, 2015, the borrower, which primarily operates as a tier 1 and tier 2 supplier in the automotive manufacturing industry, has made all principal and interest payments under a forbearance agreement with the Corporation. Based on a collateral review for this loan relationship, the Corporation established a specific impairment reserve of $2.3 million for this loan relationship as of December 31, 2015. The Corporation's nonperforming loans in the commercial loan portfolio were $71.2 million at December 31, 2015, an increase of $14.0 million, or 24%, from $57.2 million at December 31, 2014. Nonperforming loans in the commercial loan portfolio comprised 85% of total nonperforming loans at December 31, 2015, compared to 81% at December 31, 2014. The Corporation's nonperforming loans in the consumer loan portfolio were $12.7 million at December 31, 2015, a decrease of $1.3 million, or 8.9%, from $14.0 million at December 31, 2014.

Nonperforming commercial loans were $33.6 million at December 31, 2015, an increase of $12.5 million, or 59%, from $21.1 million at December 31, 2014. The increase in nonperforming commercial loans during 2015 was primarily attributable to the commercial loan relationship previously discussed. Of the $10.0 million of nonperforming loans in this customer relationship at December 31, 2015, $8.5 million were nonperforming commercial loans and $1.5 million were nonperforming commercial real estate loans. Nonperforming commercial loans comprised 1.8% of total commercial loans at December 31, 2015, compared to 1.6% at December 31, 2014. At December 31, 2015, approximately 50% of the Corporation's nonperforming commercial loans were in the manufacturing industry, with the largest concentration of these related to the customer loan relationship previously discussed. Approximately 25% of the Corporation's nonperforming commercial loans at December 31, 2015 were secured by income-producing farmland, with the largest concentration of these nonperforming commercial loans with one customer relationship totaling $3.3 million that was secured by income-producing farmland and other assets and has been in nonperforming status for over one year. The Corporation charged off $1.6 million of loans in this relationship during the fourth quarter of 2015. Accordingly, the Corporation did not require a specific impairment reserve on this loan relationship at December 31, 2015.
Nonperforming commercial real estate loans were $36.6 million at December 31, 2015, an increase of $0.9 million, or 2.7%, from $35.7 million at December 31, 2014. Nonperforming commercial real estate loans comprised 1.7% of total commercial real estate loans at December 31, 2015, compared to 2.3% at December 31, 2014. Nonperforming commercial real estate loans secured by owner occupied real estate, non-owner occupied real estate and vacant land totaled $20.9 million, $8.1 million and $7.6 million, respectively, at December 31, 2015, and comprised 2.6%, 1.4% and 18.3%, respectively, of total owner occupied real estate, non-owner occupied real estate and vacant land loans included in the Corporation's originated commercial real estate loans at December 31, 2015. At December 31, 2015, the Corporation's nonperforming commercial real estate loans were comprised of a diverse mix of commercial lines of business and were also geographically disbursed throughout the Corporation's market areas. The largest concentration of nonperforming commercial real estate loans at December 31, 2015 was one customer relationship totaling $4.7 million that was primarily secured by vacant land and has been in nonperforming status for over five years. This same customer relationship had nonperforming land development loans of $0.1 million and nonperforming residential mortgage loans of $0.4 million. At December 31, 2015, the loans in this relationship were believed to be adequately secured and the Corporation did not require a specific impairment reserve on them at that date.
Nonperforming real estate construction loans were $0.4 million at December 31, 2015, compared to $0.2 million at December 31, 2014. Nonperforming real estate construction loans comprised 0.2% of total real estate construction loans at December 31, 2015, compared to 0.1% at December 31, 2014.
Nonperforming land development loans were $0.6 million at December 31, 2015, compared to $0.3 million at December 31, 2014. Nonperforming land development loans comprised 2.7% of total land development loans at December 31, 2015, compared to 1.5% at December 31, 2014. At December 31, 2015, nonperforming land development loans were secured primarily by residential real estate improved lots and housing units.
At December 31, 2015, the Corporation had nonperforming loans in the commercial loan portfolio of $2.1 million that were secured by real estate and were in various stages of foreclosure, compared to $2.2 million at December 31, 2014.

Nonperforming Loans — Consumer Loan Portfolio
Nonperforming residential mortgage loans were $9.0 million at December 31, 2015, a decrease of $1.5 million, or 14%, from $10.5 million at December 31, 2014. Nonperforming residential mortgage loans comprised 0.6% of total residential mortgage loans at December 31, 2015, compared to 0.9% of total residential mortgage loans at December 31, 2014. At December 31, 2015, a total of $2.9 million of nonperforming residential mortgage loans were in various stages of foreclosure, compared to $2.3 million at December 31, 2014.
Nonperforming consumer installment loans were $0.5 million at both December 31, 2015 and December 31, 2014 and comprised less than 0.1% of total consumer installment loans at those dates.
Nonperforming home equity loans were $3.2 million at December 31, 2015, an increase of $0.2 million, or 7.7%, from $3.0 million at December 31, 2014. Nonperforming home equity loans comprised 0.5% of total home equity loans at both December 31, 2015 and December 31, 2014.
Troubled Debt Restructurings (TDRs)
The generally unfavorable economic climate that had existed in Michigan during the most recent economic downturn resulted in a large number of both business and consumer customers experiencing cash flow issues making it difficult to maintain their loan balances in a performing status. The Corporation determined that it was probable that certain customers who were past due on their loans, if provided a modification of their loans by reducing their monthly payments, would be able to bring their loan relationships to a performing status. The Corporation believes loan modifications will potentially result in a lower level of loan losses and loan collection costs than if the Corporation proceeded immediately through the foreclosure process with these borrowers. The loan modifications involve granting concessions to borrowers who are experiencing financial difficulty and, therefore, these loans meet the criteria to be considered TDRs.
The Corporation's performing and nonperforming TDRs continue to accrue interest at the loan's original interest rate as the Corporation expects to collect the remaining principal balance on the loan. A TDR is reported as a nonperforming loan (nonperforming TDR) until a six-month payment history of principal and interest payments is sustained in accordance with the loan modification, at which time the Corporation moves the loan to a performing status (performing TDR). If a performing TDR becomes contractually past due more than 30 days, it is transferred to a nonperforming status. Accordingly, all of the Corporation's performing TDRs at December 31, 2015 were current or less than 30 days past due. The Corporation's nonaccrual loans that meet the definition of a TDR do not accrue interest as the Corporation does not expect to collect the full amount of principal and interest owed from the borrower on these loans.

The Corporation's performing and nonperforming TDRs in the commercial loan portfolio generally consist of loans where the Corporation has allowed borrowers to either (i) temporarily defer scheduled principal payments and make interest-only payments for a short period of time (generally six months to one year) at the stated interest rate of the original loan agreement, (ii) lower payments due to a modification of the loan's original contractual terms, or (iii) enter into moderate extensions of the loan's original contractual maturity date. These TDRs are individually evaluated for impairment. Based on this evaluation, the Corporation does not expect to incur a loss on these TDRs based on its assessment of the borrowers' expected cash flows, as the pre- and post-modification effective yields are approximately the same for these loans. Accordingly, no additional provision for loan losses has been recognized related to these TDRs. Nonperforming TDRs that have made at least six consecutive months of principal and interest payments under a formal modification agreement are classified by the Corporation as performing TDRs. If a TDR in the commercial loan portfolio becomes 90 days past due as to principal or interest, or if it becomes probable that any remaining

42

principal and interest payments due on the loan will not be collected in accordance with the modified contractual terms, the loan is transferred to nonaccrual TDR status.
Due to the borrowers' sustained repayment histories, the Corporation had performing TDRs in the commercial loan portfolio of $29.8 million at December 31, 2015, compared to $29.2 million at December 31, 2014. The Corporation also had nonperforming TDRs in the commercial loan portfolio of $16.3 million at December 31, 2015, compared to $15.3 million at December 31, 2014. The Corporation's nonperforming TDRs in the commercial loan portfolio are categorized as a risk grade 7 (substandard - accrual) under the Corporation's risk rating system, which is further described in Note 4 to the consolidated financial statements. The weighted average contractual interest rate of the Corporation's performing and nonperforming TDRs in the commercial loan portfolio was 5.57% at December 31, 2015, compared to 5.46% at December 31, 2014. At December 31, 2015, the Corporation had $32.7 million of nonaccrual TDRs in the commercial loan portfolio, compared to $32.6 million at December 31, 2014.

The Corporation's TDRs in the consumer loan portfolio generally consist of loans where the Corporation has reduced a borrower's monthly payments by decreasing the interest rate charged on the loan (generally to a range of 3% to 5%) for a specified period of time (generally 24 months). Once the borrowers have made at least six consecutive months of principal and interest payments under a formal modification agreement, they are classified as performing TDRs. These loans are moved to nonaccrual TDR status if the loan becomes 90 days past due as to principal or interest, or sooner if conditions warrant.
The Corporation had performing TDRs in the consumer loan portfolio of $18.0 million at December 31, 2015, compared to $16.5 million at December 31, 2014. The Corporation also had nonperforming TDRs in the consumer loan portfolio of $3.1 million at December 31, 2015, compared to $3.2 million at December 31, 2014. The weighted average contractual interest rate on the Corporation's performing and nonperforming TDRs in the consumer loan portfolio was 4.66% at both December 31, 2015 and December 31, 2014. At December 31, 2015, the Corporation had $3.3 million of nonaccrual TDRs in the consumer loan portfolio, compared to $4.6 million at December 31, 2014.
The Corporation's cumulative redefault rate as of December 31, 2015 on its performing and nonperforming TDRs, which represents the percentage of these TDRs that transferred to nonaccrual status since the Corporation began such modifications in 2009, was 18% for performing and nonperforming TDRs in the commercial loan portfolio and 19% for performing and nonperforming TDRs in the consumer loan portfolio. The Corporation's cumulative redefault rate does not include loans that have been modified while in nonaccrual status that remain in nonaccrual status as the Corporation does not expect to collect the full amount of principal and interest owed from the borrower on these loans.

Other Real Estate and Repossessed Assets
Other real estate and repossessed assets are components of nonperforming assets. These include other real estate (ORE), comprised of residential and commercial real estate and land development properties acquired through foreclosure or by acceptance of a deed in lieu of foreclosure, and repossessed assets, comprised of other personal and commercial assets. ORE totaled $9.7 million at December 31, 2015, a decrease of $4.3 million, or 30%, from $14.0 million at December 31, 2014. The decrease in ORE during 2015 was primarily related to the sales of ORE properties. Repossessed assets totaled $0.2 million at December 31, 2015, compared to $0.3 million at December 31, 2014.

The Corporation's ORE is carried at the lower of cost or fair value less estimated cost to sell. The historically large inventory of real estate properties for sale across the State of Michigan has resulted in an increase in the Corporation's carrying time and cost of holding ORE. Consequently, the Corporation had $7.0 million in ORE at December 31, 2015 that had been held in excess of one year, of which $2.1 million had been held in excess of three years.The Corporation had $5.0 million of nonperforming loans that were in the process of foreclosure at December 31, 2015.
All of the Corporation's ORE properties have been written down to fair value through a charge-off against the allowance for loan losses at the time the loan was transferred to ORE, through a subsequent write-down, recorded as an operating expense, to recognize a further market value decline of the property after the initial transfer date, or due to recording at fair value as a result of acquisition transactions. Accordingly, at December 31, 2015, the carrying value of ORE of $9.7 million was reflective of $18.9 million in charge-offs, write-downs and acquisition-related fair value adjustments and represented 34% of the contractual loan balance remaining at the time these loans were classified as nonperforming.
During 2015, the Corporation sold 337 ORE properties for net proceeds of $14.3 million. On an average basis, the net proceeds from these sales represented 140% of the carrying value of the property at the time of sale, with the net proceeds representing 66% of the remaining contractual loan balance at the time these loans were classified as nonperforming.

44

Impaired Loans
A loan is considered impaired when management determines it is probable that payment of principal and interest due will not be paid according to the original contractual terms of the loan agreement. Impaired loans are accounted for at the lower of the present value of expected cash flows discounted at the loan's original effective interest rate or the estimated fair value of the collateral, if the loan is collateral dependent. A portion of the allowance for loan losses is specifically allocated to impaired loans. The process of measuring impaired loans and the allocation of the allowance for loan losses requires judgment and estimation. The eventual outcome may differ from amounts estimated.
Impaired loans include nonaccrual loans (including nonaccrual TDRs), performing and nonperforming TDRs and acquired loans that were not performing in accordance with their original contractual terms. Impaired loans totaled $142.2 million and $134.7 million at December 31, 2015 and 2014, respectively. The increase in impaired loans during 2015 was due to an increase in nonaccrual loans largely resulting from the $10 million commercial loan relationship that was downgraded to nonaccrual status during the year, as previously discussed.

After analyzing the various components of the customer relationships and evaluating the underlying collateral of impaired loans, the Corporation determined that impaired loans in the commercial loan portfolio totaling $23.3 million at December 31, 2015 required a specific allocation of the allowance for loan losses (valuation allowance) of $6.2 million, compared to $3.6 million of impaired loans in the commercial loan portfolio at December 31, 2014 which required a valuation allowance of $1.0 million.The increase in impaired loans in the commercial loan portfolio that required a valuation allowance during 2015 was due to seven commercial loan relationships totaling $22.1 million at December 31, 2015 being classified by the Corporation as nonperforming during the year and requiring a valuation allowance of $5.7 million as of that date. The largest of these commercial loan relationships was the $10.0 million commercial loan relationship to a borrower that primarily operates as a tier 1 and tier 2 supplier in the automotive industry, as previously discussed, that required a valuation allowance of $2.3 million at December 31, 2015. Confirmed losses represent partial loan charge-offs on impaired loans due primarily to the receipt of a recent third-party property appraisal indicating the value of the collateral securing the loan was below the loan balance and management determined that full collection of the loan balance is not likely. The Corporation's performing and nonperforming TDRs in the commercial loan portfolio did not require a valuation allowance as the Corporation expected to collect the full principal and interest owed on each of these loans in accordance with their modified terms.
The Corporation generally does not recognize a valuation allowance for impaired loans in the consumer loan portfolio as these loans are comprised of smaller-balance homogeneous loans that are collectively evaluated for impairment. However, the Corporation had a valuation allowance attributable to TDRs in the consumer loan portfolio of $0.2 million at December 31, 2015, compared to $0.3 million at December 31, 2014, related to the reduction in the present value of expected future cash flows for these loans discounted at their original effective interest rates.
Impaired loans included acquired loans totaling $12.8 million and $19.9 million at December 31, 2015 and 2014, respectively, that were not performing in accordance with the original contractual terms of the loans. These loans did not require a valuation allowance as they are recorded in pools at their net realizable value based on the principal and interest the Corporation expects to collect on these loan pools. These loans are not included in the Corporation's nonperforming loans.
ALLOWANCE FOR LOAN LOSSES
The allowance for loan losses (allowance) provides for probable losses in the originated loan portfolio that have been identified with specific customer relationships and for probable losses believed to be inherent in the remainder of the originated loan portfolio but that have not been specifically identified. The allowance is comprised of specific valuation allowances (assessed for originated loans that have known credit weaknesses), pooled allowances based on assigned risk ratings and historical loan loss experience for each loan type, and a qualitative allowance based on environmental factors that take into consideration risks inherent in the originated loan portfolio that differ from historical loan loss experience. Management evaluates the allowance on a quarterly basis in an effort to ensure the level is adequate to absorb probable losses inherent in the loan portfolio. This evaluation process is inherently subjective as it requires estimates that may be susceptible to significant change and has the potential to affect net income materially. The Corporation's methodology for measuring the adequacy of the allowance is comprised of several key elements, which include a review of the loan portfolio, both individually and by category, and consideration of changes in the mix and volume of the loan portfolio, actual delinquency and loan loss experience, review of collateral values, the size and financial condition of the borrowers, industry and geographical exposures within the portfolio, economic conditions and employment levels of the Corporation's local markets and other factors affecting business sectors. Management believes that the allowance is currently maintained at an appropriate level, considering the inherent risk in the loan portfolio. Future significant adjustments to the allowance may be necessary due to changes in economic conditions, delinquencies or the level of loan losses incurred.

The allowance of the acquired loan portfolio was not carried over on the date of acquisition. The acquired loans were recorded at their estimated fair values at the date of acquisition, with the estimated fair values including a component for expected credit losses. Acquired loans are subsequently evaluated for further credit deterioration in loan pools, which consist of loans with similar credit risk characteristics. If an acquired loan pool experiences a decrease in expected cash flows, as compared to those expected at the acquisition date, a portion of the allowance is allocated to acquired loans. There was no allowance needed for the acquired loan portfolio at December 31, 2015. At December 31, 2014, the allowance on the acquired loan portfolio was $0.5 million and was related to two consumer loan pools from the OAK transaction performing slightly below original expectations.
The allocation of the allowance for loan losses in Table 7 is based upon ranges of estimates and is not intended to imply either limitations on the usage of the allowance or exactness of the specific amounts. The entire allowance attributable to originated loans is available to absorb future loan losses within the originated loan portfolio without regard to the categories in which the loan losses are classified. The allocation of the allowance is based upon a combination of factors, including historical loss factors, credit-risk grading, past-due experiences, and other factors, as discussed above.

DEPOSITS
Total deposits were $7.46 billion at December 31, 2015, an increase of $1.38 billion, or 23%, from total deposits at December 31, 2014 of $6.08 billion. The increase in total deposits during 2015 was attributable to organic growth in customer deposits of $382 million, or 6.3%, and deposits acquired in the Lake Michigan and Monarch acquisitions of $1.07 billion, including interest- and noninterest-bearing demand deposits and savings deposits totaling $589 million, customer certificates of deposit of $202 million, and brokered deposits of $278 million. The organic growth in customer deposits during 2015 included increases in interest- and noninterest-bearing demand deposits and savings deposits of $479 million that were partially offset by a decline in certificate of deposit accounts of $97 million. Interest- and noninterest-bearing demand deposit and savings accounts were $5.81 billion at December 31, 2015, compared to $4.74 billion at December 31, 2014. Certificates of deposit were $1.65 billion at December 31, 2015, compared to $1.34 billion at December 31, 2014. Total deposits increased $957 million during 2014 due primarily to $794 million of deposits acquired in the Northwestern acquisition.
It is the Corporation's strategy to develop customer relationships that will drive core deposit growth and stability. The Corporation's competitive position within many of its market areas has historically limited its ability to materially increase core deposits without adversely impacting the weighted average cost of the deposit portfolio. While competition for core deposits remained strong throughout the Corporation's markets during 2015 and 2014, the Corporation's efforts to expand its deposit relationships with existing customers, the Corporation's financial strength and a general trend in customers holding more liquid assets have resulted in the Corporation continuing to experience increases in customer deposits.
The growth of the Corporation's deposits can be impacted by competition from other investment products, such as mutual funds and various annuity products. These investment products are sold by a wide spectrum of organizations, such as brokerage and insurance companies, as well as by financial institutions. In response to the competition for other investment products, Chemical Bank, through its Chemical Financial Advisors program, offers a wide array of mutual funds, annuity products and marketable securities through an alliance with an independent, registered broker/dealer. The Corporation also competes with credit unions in most of its markets. These institutions are challenging competitors, as credit unions are exempt from federal income taxes, allowing them to potentially offer higher deposit rates.

48

At December 31, 2015, the Corporation's time deposits, which consist of certificates of deposit, totaled $1.65 billion, of which $904 million have stated maturities in 2016, although the Corporation expects the majority of these to be renewed by customers or transferred to another deposit product offered by the Corporation.

BORROWED FUNDS
Borrowed funds consist of short-term borrowings and other borrowings. Short-term borrowings, which generally have an original term to maturity of 30 days or less, consist of securities sold under agreements to repurchase with customers, short-term Federal Home Loan Bank (FHLB) advances, and federal funds purchased. Other borrowings consist of securities sold under agreements to repurchase with an unaffiliated third-party financial institution, long-term FHLB advances, a non-revolving line-of-credit, and subordinated debentures.
Short-term Borrowings
Short-term borrowings were $397.2 million, $389.5 million and $327.4 million at December 31, 2015, 2014 and 2013, respectively. Short-term borrowings increased $7.7 million, or 2.0%, during 2015 and $62.0 million, or 19%, during 2014. The increase in short-term borrowings during 2014 was primarily due to federal funds purchased and short-term FHLB advances utilized by the Corporation to fund short-term liquidity needs resulting from loan growth.

Securities sold under agreements to repurchase with customers represent funds deposited by customers, generally on an overnight basis, that are collateralized by investment securities owned by Chemical Bank, as these deposits are not covered by Federal Deposit Insurance Corporation (FDIC) insurance. These funds have been a stable source of liquidity for Chemical Bank, much like its core deposit base, and are generally only provided to customers that have an established banking relationship with Chemical Bank. The Corporation's securities sold under agreements to repurchase do not qualify as sales for accounting purposes.
FHLB advances are borrowings from the Federal Home Loan Bank of Indianapolis that are generally used to fund loans and are secured by both a blanket security agreement of residential mortgage first lien loans with an aggregate book value equal to at least 140% of the advances and FHLB capital stock owned by Chemical Bank. The carrying value of residential mortgage first lien loans eligible as collateral under the blanket security agreement was $1.34 billion at December 31, 2015. The Corporation relies on short-term FHLB advances to cover short-term liquidity needs.
Federal funds purchased represent unsecured borrowings from nonaffiliated third-party financial institutions, generally on an overnight basis, to cover short-term liquidity needs.
Other Borrowings
Other borrowings were $242.4 million at December 31, 2015. The Corporation had no other borrowings at December 31, 2014 or 2013. The Corporation's other borrowings were obtained as a result of the acquisitions of Lake Michigan and Monarch, and the Corporation's borrowing of $100 million of long-term FHLB advances in the third quarter of 2015 which were used to replace short-term FHLB advances.

The Corporation borrowed $100 million of long-term FHLB advances, which consist of three- and five-year fixed-rate advances with a weighted average interest rate of 1.48%, during the third quarter of 2015 in advance of anticipated increases in market interest rates. The Corporation also acquired long-term FHLB advances as a result of the Lake Michigan and Monarch transactions totaling $81.5 million. These acquired long-term FHLB advances have a weighted average interest rate of 1.33% and an average maturity date of 2.1 years as of December 31, 2015.
Securities sold under agreements to repurchase with an unaffiliated third-party financial institution represent financing arrangements that are secured by available-for-sale investment securities. These borrowings were obtained as part of the Lake Michigan acquisition. The Corporation intends to pay off these borrowings as they mature, with remaining contractual maturities of $8.3 million in 2016 and $9.1 million in 2017.
The Corporation entered into a $25 million secured non-revolving line-of-credit in May 2015 with an unaffiliated third-party financial institution. The Corporation drew on the entire amount of the line-of-credit in order to partially fund the cash portion of the purchase price consideration for the Lake Michigan transaction. This line-of-credit bears a variable rate of interest which is based on the one-, two-, or three-month LIBOR, as periodically selected by the Corporation, plus a fixed stated rate, and matures in May 2016.
Lake Michigan created three entities, Lake Michigan Financial Capital Trust I (LMFCTI), Lake Michigan Financial Capital Trust II (LMFCTII), and Lake Michigan Financial Capital Trust III (LMFCTIII), which were formed solely to issue capital securities in the form of cumulative preferred securities. The cumulative preferred securities issued by these trust entities were guaranteed by Lake Michigan and therefore were considered subordinated debt of Lake Michigan. As a result of the Lake Michigan transaction, the subordinated debt resulting from LMFCTI and LMFCTII became debt obligations (subordinated debentures) of the Corporation in the amount of $18.5 million. LMFCTIII, which held a $10.3 million trust preferred security that was 100% due to the Corporation, was settled at par and the entity was dissolved in conjunction with the acquisition of Lake Michigan on May 31, 2015. The subordinated debentures pay interest based on a floating rate tied to the three-month LIBOR plus an index. These subordinated debentures qualify as regulatory capital for purposes of computing the tier 1 and total risk-based capital ratios. LMFCTI and LMFCTII have stated maturity dates of October 31, 2032 and May 1, 2034, respectively, although the Corporation has notified the respective trust's trustee of its intent to pay off these debt obligations during the first quarter of 2016.

The Corporation has paid regular cash dividends every quarter since it began operating as a bank holding company in 1973. The earnings of Chemical Bank have been the principal source of funds to pay cash dividends to shareholders. Over the long-term, cash dividends to shareholders are dependent upon earnings, capital requirements, legal and regulatory restraints and other factors affecting Chemical Bank. Refer to Note 20 to the consolidated financial statements for a further discussion of factors affecting cash dividends.
CAPITAL
Capital supports current operations and provides the foundation for future growth and expansion. Total shareholders' equity was $1.02 billion at December 31, 2015, an increase of $219 million, or 27%, from total shareholders' equity of $797 million at December 31, 2014. The increase in shareholders' equity during 2015 was primarily attributable to the Corporation issuing common stock valued at $133 million and $27 million for the acquisitions of Lake Michigan and Monarch, respectively. In addition, the Corporation's net income in 2015 exceeded cash dividends paid to shareholders by $50 million. Shareholders' equity increased $100 million in 2014, with the increase attributable to the Corporation raising $76.2 million of capital in the second quarter of 2014 and the Corporation's net income exceeding cash dividends paid to shareholders by $32.6 million, which were partially offset by an $11.9 million increase in accumulated other comprehensive losses resulting from an increase in the projected benefit obligation for the Corporation's pension plan. Book value per common share at December 31, 2015 and 2014 was $26.62 and $24.32, respectively.
The ratio of shareholders' equity to total assets was 11.1% at December 31, 2015, compared to 10.9% at December 31, 2014. The Corporation's tangible equity, which is defined as total shareholders' equity less goodwill and other acquired intangible assets, totaled $717 million and $601 million at December 31, 2015 and 2014, respectively. The Corporation's tangible equity to tangible assets ratio was 8.1% and 8.4% at December 31, 2015 and 2014, respectively. The decrease in the Corporation's tangible equity to tangible assets ratio during 2015 was primarily attributable to $102 million of goodwill generated in the acquisition of Lake Michigan.

52

Regulatory Capital
Under the regulatory "risk-based" capital guidelines in effect for both banks and bank holding companies, minimum capital levels are based upon perceived risk in the Corporation's and Chemical Bank's various asset categories. These guidelines assign risk weights to on- and off-balance sheet items in arriving at total risk-weighted assets. Regulatory capital is divided by the computed total of risk-weighted assets to arrive at the risk-based capital ratios. Risk-weighted assets for the Corporation and Chemical Bank totaled $7.14 billion and $7.13 billion, respectively, at December 31, 2015, compared to $5.70 billion for both the Corporation and Chemical Bank at December 31, 2014. The increase in risk-weighted assets during 2015 was largely attributable to the acquisitions of Lake Michigan and Monarch, in addition to organic loan growth.
In July 2013, the Federal Reserve Board and Federal Deposit Insurance Corporation (FDIC) approved final rules implementing the Basel Committee on Banking Supervision's (BCBS) capital guidelines for U.S. banks (commonly referred to as Basel III). Beginning January 1, 2015, the Basel III capital rules include a new minimum common equity Tier 1 capital to risk-weighted assets (CET) ratio of 4.5%, in addition to raising the minimum ratio of Tier 1 capital to risk-weighted assets from 4.0% to 6.0% and requiring a minimum leverage ratio of 4.0%. The Basel III capital rules also establish a new capital conservation buffer of 2.5% of risk-weighted assets, which is phased-in over a four-year period beginning January 1, 2016.
The Corporation and Chemical Bank both continue to maintain strong capital positions, which significantly exceeded the minimum levels prescribed by the Board of Governors of the Federal Reserve System (Federal Reserve) at December 31, 2015, as shown in the following schedule:

See Note 20 to the consolidated financial statements for more information regarding the Corporation's and Chemical Bank's regulatory capital ratios.
Common Stock Repurchase Programs
From time to time, the board of directors of the Corporation approves common stock repurchase programs allowing the repurchase of shares of the Corporation's common stock in the open market. The repurchased shares are available for later reissuance in connection with potential future stock dividends, employee benefit plans and other general corporate purposes. Under these programs, the timing and actual number of shares subject to repurchase are at the discretion of management and are contingent on a number of factors, including the projected parent company cash flow requirements and the Corporation's share price.
In January 2008, the board of directors of the Corporation authorized the repurchase of up to 500,000 shares of the Corporation's common stock under a stock repurchase program. In November 2011, the board of directors of the Corporation reaffirmed the stock buy-back authorization with the qualification that the shares may only be repurchased if the share price is below the tangible book value per share of the Corporation's common stock at the time of the repurchase. Since the January 2008 authorization, no shares have been repurchased. At December 31, 2015, there were 500,000 remaining shares available for repurchase under the Corporation's stock repurchase program.
Shelf Registration
On June 12, 2014, the Corporation filed an automatic shelf registration statement on Form S-3 with the Securities and Exchange Commission (SEC) for an indeterminate amount of securities, which became immediately effective. The shelf registration statement provides the Corporation with the ability to raise capital, subject to SEC rules and limitations, if the board of directors of the Corporation decides to do so.

NET INTEREST INCOME
Net interest income is the difference between interest income on earning assets, such as loans, investment and non-marketable equity securities and interest-bearing deposits with the FRB and other banks, and interest expense on liabilities, such as deposits and borrowings. Net interest income is the Corporation's largest source of net revenue (net interest income plus noninterest income), representing 77% of net revenue in both 2015 and 2014 and 76% of net revenue in 2013. Net interest income, on a fully taxable equivalent (FTE) basis, is the difference between interest income and interest expense adjusted for the tax benefit received on tax-exempt commercial loans and investment securities. Net interest margin is calculated by dividing net interest income (FTE) by average interest-earning assets. Net interest spread is the difference between the average yield on interest-earning assets and the average cost of interest-bearing liabilities. Because noninterest-bearing sources of funds, or free funds (principally demand deposits and shareholders' equity), also support earning assets, the net interest margin exceeds the net interest spread.
Net interest income (FTE) in 2015, 2014 and 2013 was $281.5 million, $218.5 million and $202.0 million, respectively. The presentation of net interest income on a FTE basis is not in accordance with GAAP, but is customary in the banking industry. This non-GAAP measure ensures comparability of net interest income arising from both taxable and tax-exempt loans and investment securities. The adjustments to determine tax equivalent net interest income were $7.45 million, $5.98 million and $5.36 million for 2015, 2014 and 2013, respectively. These adjustments were computed using a 35% federal income tax rate.
Table 9 presents the average daily balances of the Corporation's major categories of assets and liabilities, interest income and expense on a FTE basis, average interest rates earned and paid on the assets and liabilities, net interest income (FTE), net interest spread and net interest margin for 2015, 2014 and 2013.

Net interest income (FTE) of $281.5 million in 2015 was $62.9 million, or 29%, higher than net interest income (FTE) of $218.5 million in 2014. The increase in net interest income (FTE) in 2015, compared to 2014, was primarily attributable to an increase of $1.61 billion in the average volume of loans outstanding, including the impact of $1.58 billion of loans acquired in the three acquisitions that occurred during 2015 and 2014 and the favorable impact of interest-bearing deposits, primarily certificates of deposit, repricing lower during 2015. The increases attributable to loan growth and deposits repricing were partially offset by the unfavorable impact of interest-earning assets, primarily loans, repricing during 2015 and an increase in higher-cost wholesale funding resulting from the Lake Michigan acquisition and the Corporation utilizing long-term FHLB advances to partially fund loan growth. The net interest margin was 3.58% in 2015, compared to 3.59% in 2014. The average yield on interest-earning assets decreased 2 basis points to 3.81% in 2015 from 3.83% in 2014, with the decrease primarily attributable to loans repricing at lower interest rates. The average yield on loans decreased 9 basis points to 4.16% in 2015 from 4.25% in 2014, with declines occurring across all major loan categories. The average cost of interest-bearing liabilities decreased 3 basis points to 0.31% in 2015 from 0.34% in 2014, with the decrease attributable to the repricing of time deposits at lower interest rates as they matured and were renewed in the continued low interest rate environment.
Net interest income (FTE) of $218.5 million in 2014 was $16.5 million, or 8.2%, higher than net interest income (FTE) of $202.0 million in 2013. The increase in net interest income (FTE) in 2014, compared to 2013, was primarily attributable to an increase of $617 million in the average volume of loans outstanding, including the impact of the $475 million of loans acquired in the acquisition of Northwestern on October 31, 2014, and the favorable impact of interest-bearing deposits, primarily certificates of deposit, repricing lower during 2014. The increases attributable to loan growth and deposits repricing were partially offset by the unfavorable impact of interest-earning assets, primarily loans, repricing during 2014. The net interest margin was 3.59% in both 2014 and 2013. The average yield on interest-earning assets decreased 7 basis points to 3.83% in 2014 from 3.90% in 2013, with the decrease primarily attributable to loans repricing at lower interest rates. The average yield on loans decreased 27 basis points to 4.25% in 2014 from 4.52% in 2013, with declines occurring across all major loan categories. The average cost of interest-bearing liabilities decreased 8 basis points to 0.34% in 2014 from 0.42% in 2013, with the decrease attributable to the repricing of time deposits at lower interest rates as they matured and were renewed in the continued low interest rate environment.
Changes in the Corporation's net interest income are influenced by a variety of factors, including changes in the level and mix of interest-earning assets and interest-bearing liabilities, current and prior years' interest rate changes, the level and direction of interest rates, the difference between short-term and long-term interest rates (the steepness of the yield curve) and the general strength of the economies in the Corporation's markets. Risk management plays an important role in the Corporation's level of net interest income. The ineffective management of credit risk, and more significantly interest rate risk, can adversely impact the Corporation's net interest income. Management monitors the Corporation's consolidated statement of financial position to reduce the potential adverse impact on net interest income caused by significant changes in interest rates. The Corporation's policies in this regard are further discussed in the section captioned "Market Risk" in Item 7A of this report.
The Federal Reserve influences the general market rates of interest, including the deposit and loan rates offered by many financial institutions. The prime interest rate, which is the rate offered on loans to borrowers with strong credit, was 3.25% at the end of 2008 and remained at this historically low rate until December 2015, when it was increased to 3.50%. The prime interest rate has historically been 300 basis points higher than the federal funds rate. The majority of the Corporation's variable interest rate loans in the commercial loan portfolio are tied to the prime rate.
The Corporation is primarily funded by core deposits, which is a lower-cost funding base than wholesale funding and historically has had a positive impact on the Corporation's net interest income and net interest margin. Based on the current historically low level of market interest rates and the Corporation's current low levels of interest rates on its core deposit transaction accounts, further market interest rate reductions would not result in a significant decrease in interest expense.

PROVISION FOR LOAN LOSSES
The provision for loan losses (provision) is an increase to the allowance, as determined by management, to provide for probable losses inherent in the originated loan portfolio and for impairment in pools of acquired loans that results from the Corporation experiencing a decrease, if any, in expected cash flows of acquired loans during each reporting period. The provision was $6.5 million in 2015, compared to $6.1 million in 2014 and $11.0 million in 2013.
The Corporation experienced net loan charge-offs of $8.9 million in 2015, compared to $9.5 million in 2014 and $16.4 million in 2013. Net loan charge-offs as a percentage of average loans were 0.13% in 2015, compared to 0.19% in 2014 and 0.38% in 2013. Net loan charge-offs in the commercial loan portfolio totaled $4.2 million in 2015, compared to $3.8 million in 2014 and $9.4 million in 2013 and represented 47% of total net loan charge-offs during 2015 compared to 40% during 2014 and 57% during 2013. The commercial loan portfolio's net loan charge-offs in 2015 were not concentrated in any one industry or borrower, with the exception of a $1.6 million net loan charge-off from one commercial loan relationship. Net loan charge-offs in the consumer loan portfolio totaled $4.7 million in 2015, compared to $5.7 million in 2014 and $7.0 million in 2013.

The Corporation's provision of $6.5 million in 2015 was $2.4 million lower than 2015 net loan charge-offs, while the provision of $6.1 million in 2014 was $3.4 million lower than 2014 net loan charge-offs. The Corporation's provision for loan losses was lower than net loan charge-offs during both 2015 and 2014, despite significant organic growth in its loan portfolio, due to the overall strong credit quality of the loan portfolio.

(1) Excludes nonrecurring items such as gain on the sale of investment securities, closed branch offices and other assets and merchant card servicing business. See the discussion below for a description and the amounts of these nonrecurring items.
Noninterest income was $80.2 million in 2015, $63.1 million in 2014 and $60.4 million in 2013. Noninterest income in 2015 included nonrecurring income of $0.9 million, including $0.6 million attributable to available-for-sale investment securities gains and $0.3 million attributable to gains on the sales of closed branch offices and other assets. Noninterest income in 2014 included nonrecurring income of $0.4 million attributable to a gain from the sale of the merchant card servicing business acquired by the Corporation in the Northwestern transaction. Noninterest income in 2013 included nonrecurring income of $1.6 million, including $1.1 million attributable to available-for-sale investment securities gains and $0.5 million attributable to gains on the sales of closed branch offices and other assets. Excluding nonrecurring income, noninterest income increased $16.6 million, or 27%, in 2015, compared to 2014, with the increase attributable to all major components of noninterest income that was largely driven by the acquisitions of Lake Michigan, Monarch and Northwestern. Excluding nonrecurring income, noninterest income increased $3.9 million, or 6.7%, in 2014, compared to 2013, with the increase attributable to all major components of noninterest income, except for mortgage banking revenue, that was partially driven by the acquisition of Northwestern.
Service charges and fees on deposit accounts, which include overdraft/non-sufficient funds fees, checking account fees and other deposit account charges, were $25.5 million in 2015, $22.4 million in 2014 and $21.9 million in 2013. Service charges and fees on deposit accounts increased $3.1 million, or 14%, in 2015, compared to 2014, due primarily to additional fees earned as a result of the three aforementioned transactions. Service charges and fees on deposit accounts increased $0.5 million, or 2.2%, in 2014, compared to 2013, due primarily to additional fees earned as a result of the Northwestern transaction. Overdraft/non-sufficient funds fees included in service charges and fees on deposit accounts were $18.7 million in 2015, compared to $17.6 million in both 2014 and 2013.
Wealth management revenue is comprised of investment fees that are generally based on the market value of assets within a trust account, custodial account fees and fees from the sale of investment products. Volatility in the equity and bond markets impacts the market value of trust assets and the related investment fees. Wealth management revenue was $20.6 million in 2015, $16.0 million in 2014 and $14.0 million in 2013. Wealth management revenue increased $4.5 million, or 28%, in 2015, compared to 2014, and wealth management revenue increased $2.0 million, or 14%, in 2014, compared to 2013, with the increases due primarily to a combination of improving equity market performance that led to increased assets under management, growth in assets under management resulting from new customer accounts and the impact of the Northwestern transaction. Wealth management revenue includes fees from the sale of investment products offered through the Chemical Financial Advisors program. Fees from this program totaled $3.9 million in 2015, compared to $3.7 million in 2014 and $3.8 million in 2013.

57

At December 31, 2015, the estimated fair value of trust assets under administration was $3.71 billion (including discretionary assets of $2.11 billion and nondiscretionary assets of $1.60 billion), compared to $3.73 billion at December 31, 2014 (including discretionary assets of $2.10 billion and nondiscretionary assets of $1.63 billion), and $2.51 billion at December 31, 2013 (including discretionary assets of $1.44 billion and nondiscretionary assets of $1.07 billion). The Corporation also had customer assets within the Chemical Financial Advisors program of $873 million at December 31, 2015, compared to $878 million at December 31, 2014 and $737 million at December 31, 2013. The acquisition of Northwestern on October 31, 2014 added approximately $900 million of trust assets under administration and $100 million of customer assets within the Chemical Financial Advisors program.
Electronic banking fees, which represent income earned by the Corporation from ATM transactions, debit card activity and internet banking fees, were $19.1 million in 2015, $13.5 million in 2014 and $12.2 million in 2013. Electronic banking fees increased $5.6 million, or 42%, in 2015, compared to 2014, due to increased customer debit card and ATM transaction activity largely resulting from the impact of the three aforementioned transactions, while the increase of $1.3 million, or 10%, in 2014, compared to 2013, was due to a combination of increased debit card and ATM transaction activity and the impact of the Northwestern transaction.
Mortgage banking revenue (MBR) includes revenue from originating, selling and servicing residential mortgage loans for the secondary market. MBR was $6.1 million in 2015, $5.0 million in 2014 and $5.3 million in 2013. MBR increased $1.1 million, or 22%, in 2015, compared to 2014, due primarily to a higher volume of loans sold in the secondary market. MBR decreased $0.3 million, or 5.5%, in 2014, compared to 2013, due primarily to a lower volume of loans sold in the secondary market. The Corporation sold $223 million of residential mortgage loans in the secondary market during 2015, compared to $149 million during 2014 and $211 million during 2013. At December 31, 2015, the Corporation was servicing $2.08 billion of residential mortgage loans that had been originated in the Corporation's market areas and subsequently sold in the secondary market, compared to $2.09 billion at December 31, 2014 and $887 million at December 31, 2013. The significant increase in the Corporation's loan servicing portfolio during 2014 was attributable to the Northwestern transaction.
The Corporation sells residential mortgage loans in the secondary market on both a servicing retained and servicing released basis. These sales include the Corporation entering into residential mortgage loan sale agreements with buyers in the normal course of business. The agreements contain provisions that include various representations and warranties regarding the origination, characteristics and underwriting of the mortgage loans. The recourse of the buyer may result in either indemnification of the loss incurred by the buyer or a requirement for the Corporation to repurchase a loan that the buyer believes does not comply with the representations included in the loan sale agreement. Repurchase demands and loss indemnifications received by the Corporation are reviewed by a senior officer on a loan-by-loan basis to validate the claim made by the buyer. The Corporation maintains a reserve for probable losses expected to be incurred from loans previously sold in the secondary market. This contingent liability is based on trends in repurchase and indemnification requests, actual loss experience, information requests, known and inherent risks in the sale of loans in the secondary market and current economic conditions. The Corporation records losses resulting from the repurchase of loans previously sold in the secondary market, as well as adjustments to estimates of future probable losses, as part of its MBR in the period incurred. The Corporation's reserve for probable losses was $4.1 million at December 31, 2015, compared to $3.0 million at December 31, 2014, with the increase during 2015 attributable to the reserve for probable losses associated with loans previously sold in the secondary market by both Lake Michigan and Monarch.
All other categories of noninterest income, including other fees for customer services, insurance commissions and other noninterest income, excluding the nonrecurring income previously discussed, totaled $8.0 million in 2015, $5.7 million in 2014 and $5.3 million in 2013. Other fees for customer services include revenue from safe deposit boxes, credit card referral fees, wire transfer fees, letter of credit fees and other fees for services. Insurance commissions primarily consist of title insurance commissions received on title insurance policies issued for customers of Chemical Bank. The increase in all other categories of noninterest income during 2015, compared to 2014, was largely attributable to an increase in volume of customer services resulting from the impact of the three aforementioned transactions. The increase was also due in part to additional revenue from bank owned life insurance and rental income sources resulting from the Lake Michigan transaction.

Total operating expenses were $223.9 million in 2015, $179.9 million in 2014 and $164.9 million in 2013. Operating expenses included nonrecurring acquisition-related expenses of $7.8 million in 2015 and $6.4 million in 2014. Excluding nonrecurring transaction-related expenses, operating expenses of $216.1 million in 2015 increased $42.6 million, or 25%, over operating expenses of $173.5 million in 2014, due largely to a combination of incremental operating costs associated with the acquisitions of Lake Michigan, Monarch and Northwestern, increased employee compensation costs resulting from merit increases, market-based salary adjustments and higher pension costs. Excluding nonrecurring acquisition-related expenses, operating expenses increased $8.6 million, or 5.2%, in 2014, compared to 2013, due largely to a combination of incremental operating costs associated with the acquisition of Northwestern, increased employee compensation costs resulting from merit increases, market-based salary adjustments and higher group health care costs, and higher expenses associated with occupancy, equipment and net other real estate costs. These increases were partially offset by lower pension and donations expense.
Salaries and wages were $104.5 million in 2015, $83.2 million in 2014 and $78.0 million in 2013. Salaries and wages expense increased $21.3 million, or 26%, in 2015, compared to 2014, due primarily to merit increases and market-based salary adjustments that took effect at the beginning of 2015 and incremental costs associated with the three aforementioned transactions. Salaries and wages expense increased $5.2 million, or 6.7%, in 2014, compared to 2013, due primarily to merit increases and market-based salary adjustments that took effect at the beginning of 2014 and incremental costs associated with the Northwestern transaction. Performance-based compensation expense was $11.3 million in 2015, compared to $8.6 million in 2014 and $8.9 million in 2013.
Employee benefits expense was $23.4 million in 2015, $19.3 million in 2014 and $18.4 million in 2013. Employee benefits expense increased $4.1 million, or 21%, in 2015, compared to 2014, due primarily to incremental costs associated with the three aforementioned transactions and higher pension plan expenses. Employee benefits expense increased $0.9 million, or 5.0%, in 2014, compared to 2013, due primarily to higher group health care costs and incremental costs associated with the Northwestern transaction, which were partially offset by lower pension plan expenses. Pension plan expenses were $1.6 million in 2015, zero in 2014 and $1.7 million in 2013. The fluctuations in pension plan expenses are largely attributable to changes in the discount rate used to value the pension plan's projected benefit obligations.

59

Compensation expenses, which include salaries and wages and employee benefits, as a percentage of total operating expenses were 57.1% in 2015, 57.0% in 2014 and 58.5% in 2013.
Occupancy expense was $18.2 million in 2015, $15.8 million in 2014 and $13.9 million in 2013. Occupancy expense increased $2.4 million, or 15%, in 2015, compared to 2014, due to incremental operating costs associated with the three aforementioned transactions. Occupancy expense increased $1.9 million, or 14%, in 2014, compared to 2013, due largely to incremental operating costs associated with the Northwestern transaction. Occupancy expense included depreciation expense on buildings of $4.8 million in 2015, $4.0 million in 2014 and $3.7 million in 2013.
Equipment and software expense was $18.6 million in 2015, $14.7 million in 2014 and $13.7 million in 2013. Equipment and software expense increased $3.8 million, or 26%, in 2015, compared to 2014, due primarily to incremental operating costs associated with the three aforementioned transactions. Equipment and software expense increased $1.0 million, or 7.3%, in 2014, compared to 2013, due to incremental operating costs associated with the Northwestern transaction and higher software maintenance and equipment costs that were partially offset by lower depreciation expense. Equipment and software expense included depreciation expense on equipment of $6.2 million in 2015, compared to $4.8 million in 2014 and $5.0 million in 2013.
Outside processing and services fees are largely comprised of amounts paid to third-party vendors related to the outsourcing of certain day-to-day functions that are integral to the Corporation's ability to provide services to its customers, including such things as the Corporation's debit card, electronic banking and wealth management platforms. Outside processing and service fees were $15.2 million in 2015, $11.6 million in 2014 and $11.1 million in 2013. Outside processing and service fees increased $3.6 million, or 31%, in 2015, compared to 2014, due largely to incremental operating costs associated with the three aforementioned transactions, including increased third-party volume-based costs. Outside processing and service fees increased $0.5 million, or 4.1%, in 2014, compared to 2013, due largely to incremental operating costs associated with the Northwestern transaction.
Professional fees were $4.8 million in 2015, $3.6 million in 2014 and $3.8 million in 2013. Professional fees increased $1.3 million, or 36%, in 2015, compared to 2014, with the increase largely attributable to additional legal fees incurred by the Corporation in defense of various litigation matters. Professional fees decreased $0.2 million, or 5.3%, in 2014, compared to 2013.
FDIC insurance premiums were $5.5 million in 2015, $4.3 million in 2014 and $4.4 million in 2013. The increase in FDIC insurance premiums in 2015, compared to 2014, was attributable to a significant increase in the Corporation's assessment base, which consists of average consolidated total assets less average Tier 1 capital, largely resulting from the three aforementioned transactions, which was partially offset by reductions in its assessment rate resulting from improvement in the Corporation's earnings and the overall credit quality of its loan portfolio.
Credit-related expenses are comprised of other real estate (ORE) net costs and loan collection costs. ORE net costs are comprised of costs to carry ORE, such as property taxes, insurance and maintenance costs, fair value write-downs after a property is transferred to ORE and net gains/losses from the disposition of ORE. Loan collection costs include legal fees, appraisal fees and other costs recognized in the collection of loans with deteriorated credit quality and in the process of foreclosure. Credit-related expenses were $0.6 million in 2015, $1.0 million in 2014 and $0.7 million in 2013. Credit-related expenses decreased $0.4 million, or 37% in 2015, compared to 2014, due to $0.8 million in higher net gains on the sale of ORE properties, which were partially offset by $0.4 million in higher ORE operating and loan collection costs. Credit-related expenses increased $0.3 million, or 41%, in 2014, compared to 2013, due to $1.0 million in lower net gains on the sale of ORE properties, which were partially offset by $0.7 million in lower ORE operating and loan collection costs. The Corporation recognized net gains on the sale of ORE properties of $2.7 million in 2015, $1.9 million in 2014 and $2.9 million in 2013. ORE operating and loan collection costs were $3.3 million in 2015, $2.9 million in 2014 and $3.6 million in 2013.
Donations were $1.4 million in 2015, $1.2 million in 2014 and $2.8 million in 2013. Donations increased $0.2 million, or 19%, in 2015, compared to 2014. Donations decreased $1.7 million, or 59%, in 2014, compared to 2013. The decrease in donations during 2014, compared to 2013, was due to a combination of higher contributions to the Chemical Bank Foundation (Foundation) in 2013 and higher annual and multi-year donations expense for the Corporation in 2013, as these donations are now generally granted by the Foundation. The Foundation was established in 2012 with the intent of building an endowment that will serve to award grants to organizations that improve the quality of life throughout the communities served by the Corporation. Contributions by the Corporation to the Foundation were $0.3 million in 2015, $0.3 million in 2014 and $1.4 million in 2013.
All other categories of operating expenses totaled $23.8 million in 2015, $18.8 million in 2014 and $18.1 million in 2013. All other categories of operating expenses increased $4.2 million, or 22%, in 2015, compared to 2014, due largely to incremental costs associated with the three aforementioned transactions. All other categories of operating expenses increased $0.7 million, or 4.0%, in 2014, compared to 2013, due largely to incremental costs associated with the Northwestern transaction.
The Corporation's efficiency ratio, which measures total operating expenses (excluding nonrecurring costs) divided by the sum of net interest income (FTE) and noninterest income (excluding nonrecurring income), was 59.8% in 2015, 61.6% in 2014 and 63.1% in 2013.

INCOME TAXES
The Corporation's effective federal income tax rate was 29.9% in 2015, 30.7% in 2014 and 30.0% in 2013. The fluctuations in the Corporation's effective federal income tax rate reflect changes each year in the proportion of interest income exempt from federal taxation, nondeductible interest expense and other nondeductible expenses relative to pretax income and tax credits. The modest decrease in the Corporation's effective federal income tax rate in 2015, compared to 2014, was primarily due to an increase in available tax credits resulting from investments in qualified affordable housing and other tax credit projects obtained by the Corporation as part of the Lake Michigan transaction. The increase in the Corporation's effective federal income tax rate in 2014, compared to and 2013, was due primarily to an increase in the Corporation's pre-tax income. See Note 18 to the Corporation's consolidated financial statements for additional details on the Corporation's federal income taxes. The Corporation had no uncertain tax positions during the three years ended December 31, 2015.
Tax-exempt income on a fully tax-equivalent (FTE) basis, net of related nondeductible interest expense, totaled $18.7 million in 2015, $15.0 million in 2014 and $13.4 million in 2013. Tax-exempt income (FTE) as a percentage of total interest income (FTE) was 6.3% in 2015, compared to 6.4% in 2014 and 6.1% in 2013. Income before income taxes (FTE) was $131.3 million in 2015, $95.6 million in 2014 and $86.5 million in 2013.
LIQUIDITY
Liquidity measures the ability of the Corporation to meet current and future cash flow needs in a timely manner. Liquidity risk is the adverse impact on net interest income if the Corporation was unable to meet its cash flow needs at a reasonable cost.
Liquidity is managed to ensure stable, reliable and cost-effective sources of funds are available to satisfy deposit withdrawals and lending and investment opportunities. The ability of a financial institution to meet its current financial obligations is a function of its balance sheet structure, its ability to liquidate assets and its access to alternative sources of funds. The Corporation manages its funding needs by maintaining a level of liquid funds through its asset/liability management process. The Corporation's largest sources of liquidity on a consolidated basis are the deposit base that comes from consumer, business and municipal customers within the Corporation's local markets, principal payments on loans, maturing investment securities, cash held at the Federal Reserve Bank (FRB) and unpledged investment securities available-for-sale. Customer deposits increased $1.38 billion during 2015, compared to an increase of $957 million during 2014. The increase in customer deposits during 2015 was primarily attributable to $1.07 billion of combined deposits acquired in the Lake Michigan and Monarch transactions. The increase in customer deposits in 2014 was primarily attributable to $794 million of deposits acquired in the Northwestern transaction. The Corporation's loan-to-deposit ratio increased to 97.5% at December 31, 2015 from 93.6% at December 31, 2014 as a result of loans increasing $1.58 billion, or 28%, during 2015. At December 31, 2015, the Corporation had unpledged investment securities available-for-sale with an amortized cost of $41 million and available unused wholesale sources of liquidity, including FHLB advances and borrowings from the discount window of the FRB.
The Corporation, through Chemical Bank, is a member of the FHLB and as such has access to short-term and long-term advances from the FHLB that are generally secured by residential mortgage first lien loans. The Corporation had short-term and long-term FHLB advances outstanding of $281 million at December 31, 2015. The Corporation's additional borrowing availability from the FHLB, based on its FHLB capital stock and subject to certain requirements, was $250 million at December 31, 2015. The Corporation can also borrow from the FRB's discount window to meet short-term liquidity requirements. These borrowings are required to be secured by investment securities and/or certain loan types, with each category of assets carrying various borrowing capacity percentages. At December 31, 2015, the Corporation maintained an unused borrowing capacity of $41 million with the FRB's discount window based upon pledged collateral as of that date. The Corporation also had the ability to borrow an additional $75 million in federal funds from a third-party financial institution at December 31, 2015. It is management's opinion that the Corporation's borrowing capacity could be expanded, if deemed necessary, as it has additional borrowing capacity available at the FHLB that could be used if it increased its investment in FHLB capital stock, and the Corporation has a significant amount of additional assets that could be used as collateral at the FRB's discount window.
The Corporation manages its liquidity position to provide the cash necessary to pay dividends to shareholders, invest in new subsidiaries, enter new banking markets, pursue investment opportunities and satisfy other operating requirements. The Corporation's primary source of liquidity is dividends from Chemical Bank.

61

Federal and state banking laws place certain restrictions on the amount of dividends that a bank may pay to its parent company. During 2015, Chemical Bank paid $56.9 million in dividends to the Corporation and the Corporation paid cash dividends to shareholders of $36.9 million. During 2014, Chemical Bank paid $64.5 million in dividends to the Corporation and the Corporation paid cash dividends to shareholders of $29.5 million. The Corporation had $29 million in cash at December 31, 2015, which it held in a deposit account at Chemical Bank. The Corporation intends to utilize a portion of its available cash to pay off $18.3 million in subordinated debt obligations, which were obtained as part of the Lake Michigan transaction, during the first quarter of 2016. Over the long term, cash dividends to shareholders are dependent upon earnings, capital requirements, regulatory restraints and other factors affecting Chemical Bank.
Item 7A. Quantitative and Qualitative Disclosures About Market Risk.
MARKET RISK
Market risk is the risk of loss arising from adverse changes in the fair value of financial instruments due primarily to changes in interest rates. Interest rate risk is the Corporation's primary market risk and results from timing differences in the repricing of interest rate sensitive assets and liabilities and changes in relationships between rate indices due to changes in interest rates. The Corporation's net interest income is largely dependent upon the effective management of interest rate risk. The Corporation's goal is to avoid a significant decrease in net interest income, and thus an adverse impact on the profitability of the Corporation, in periods of changing interest rates. Sensitivity of earnings to interest rate changes arises when yields on assets change differently from the interest costs on liabilities. Interest rate sensitivity is determined by the amount of interest-earning assets and interest-bearing liabilities repricing within a specific time period and the magnitude by which interest rates change on the various types of interest-earning assets and interest-bearing liabilities. The management of interest rate sensitivity includes monitoring the maturities and repricing opportunities of interest-earning assets and interest-bearing liabilities. The Corporation's interest rate risk is managed through policies and risk limits approved by the boards of directors of the Corporation and Chemical Bank and an Asset and Liability Committee (ALCO). The ALCO, which is comprised of executive and senior management from various areas of the Corporation and Chemical Bank, including finance, lending, investments and deposit gathering, meets regularly to execute asset and liability management strategies. The ALCO establishes guidelines and monitors the sensitivity of earnings to changes in interest rates. The goal of the ALCO process is to manage the impact on net interest income and the net present value of future cash flows of probable changes in interest rates within authorized risk limits.
The primary technique utilized by the Corporation to measure its interest rate risk is simulation analysis. Simulation analysis forecasts the effects on the balance sheet structure and net interest income under a variety of scenarios that incorporate changes in interest rates, the shape of the U.S. Treasury yield curve, interest rate relationships and the mix of assets and liabilities and loan prepayments. These forecasts are compared against net interest income projected in a stable interest rate environment. While many assets and liabilities reprice either at maturity or in accordance with their contractual terms, several balance sheet components demonstrate characteristics that require an evaluation to more accurately reflect their repricing behavior. Key assumptions in the simulation analysis include prepayments on loans, probable calls of investment securities, changes in market conditions, loan volumes and loan pricing, deposit sensitivity and customer preferences. These assumptions are inherently uncertain as they are subject to fluctuation and revision in a dynamic environment. As a result, the simulation analysis cannot precisely forecast the impact of rising and falling interest rates on net interest income. Actual results will differ from simulated results due to many other factors, including changes in balance sheet components, interest rate changes, changes in market conditions and management strategies.
The Corporation's interest rate sensitivity is estimated by first forecasting the next twelve months of net interest income under an assumed environment of constant market interest rates. The Corporation then compares the results of various simulation analyses to the constant interest rate forecast (base case). At December 31, 2015 and 2014, the Corporation projected the change in net interest income during the next twelve months assuming short-term market interest rates were to uniformly and gradually increase or decrease by up to 200 basis points in a parallel fashion over the entire yield curve during the same time period. Additionally, the Corporation projected the change in net interest income of an immediate 400 basis point increase in market interest rates at December 31, 2015 and 2014. The Corporation did not project an immediate 400 basis point decrease in interest rates as the likelihood of a decrease of this size was considered unlikely given prevailing interest rate levels. These projections were based on the Corporation's assets and liabilities remaining static over the next twelve months, while factoring in probable calls and prepayments of certain investment securities and residential mortgage and consumer loans. The ALCO regularly monitors the Corporation's forecasted net interest income sensitivity to ensure that it remains within established limits.

At December 31, 2015, the Corporation's model simulations projected that 100, 200 and 400 basis point increases in interest rates would result in negative variances in net interest income of 0.2%, 1.1% and 5.0%, respectively, relative to the base case over the next twelve-month period. At December 31, 2015, the Corporation's model simulations also projected that decreases in interest rates of 100 and 200 basis points would result in negative variances in net interest income of 2.1% and 5.0%, respectively, relative to the base case over the next twelve-month period. At December 31, 2014, the model simulations projected that 100, 200 and 400 basis point increases in interest rates would result in negative variances in net interest income of 0.3%, 1.5% and 6.6%, respectively, relative to the base case over the next twelve-month period, while decreases in interest rates of 100 and 200 basis points would result in negative variances in net interest income of 2.4% and 4.7%, respectively, relative to the base case over the next twelve-month period. The likelihood of a decrease in interest rates beyond 100 basis points at December 31, 2015 and 2014 was considered to be unlikely given prevailing interest rate levels.
The Corporation's model simulations at December 31, 2015 for a 200 basis point increase in interest rates resulted in a negative variance in net interest income, relative to the base case, primarily due to the Corporation deploying excess cash and maturing variable-rate investment securities into fixed-rate loans during 2015. While the model simulations projected a negative variance for a 200 basis point increase, the Corporation's net interest income is still projected to be higher if interest rates were to rise 200 basis points due to the higher yield being earned on the funds deployed into loans compared to maintaining these funds at the FRB earning 25-50 basis points or investing in lower yielding variable-rate investment securities. The Corporation's model simulations at December 31, 2015 for an immediate 400 basis point increase in interest rates also resulted in a negative variance in net interest income, relative to the base case, due to the Corporation's loan portfolio being primarily comprised of fixed-rate loans, while a majority of the Corporation's customer deposit accounts are interest-rate sensitive.
Future increases in market interest rates are not expected to have a significant immediate favorable impact on the Corporation's net interest income at the time of such increases because of the low percentage of variable interest rate loans in the Corporation's loan portfolio and a large percentage of variable interest rate loans at interest rate floors at December 31, 2015. The percentage of variable interest rate loans, which comprised approximately 26% of the Corporation's loan portfolio at December 31, 2015, has remained relatively consistent during the twelve-month period ended December 31, 2015. Approximately two-thirds of the Corporation's variable interest rate loans were at an interest rate floor with a majority expected to remain at their floor until they mature or market interest rates rise more than 50 basis points.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
NOTE 1 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Nature of Operations
Chemical Financial Corporation (Corporation) operates in a single operating segment — commercial banking. The Corporation is a financial holding company, headquartered in Midland, Michigan, that operates through one commercial bank, Chemical Bank. The Bank of Holland and The Bank of Northern Michigan were acquired in the acquisition of Lake Michigan Financial Corporation (Lake Michigan) on May 31, 2015 and were consolidated with and into Chemical Bank during the fourth quarter of 2015. Monarch Community Bank was acquired in the acquisition of Monarch Community Bancorp, Inc. (Monarch) on April 1, 2015 and was consolidated with and into Chemical Bank during the second quarter of 2015. Chemical Bank operates within the State of Michigan as a state-chartered commercial bank. Chemical Bank operates through an internal organizational structure of four regional banking units and offers a full range of traditional banking and fiduciary products and services to the residents and business customers in the bank's geographical market areas. The products and services offered by the regional banking units, through branch banking offices, are generally consistent throughout the Corporation, as is the pricing of those products and services. The marketing of products and services throughout the Corporation's regional banking units is generally uniform, as many of the markets served by the regional banking units overlap. The distribution of products and services is uniform throughout the Corporation's regional banking units and is achieved primarily through retail branch banking offices, automated teller machines and electronically accessed banking products.
The Corporation's primary sources of revenue are from its loan products and investment securities, service charges and fees from customer deposit accounts and wealth management revenue.
Accounting Standards Codification
The Financial Accounting Standards Board's (FASB) Accounting Standards Codification (ASC) became effective on July 1, 2009. At that date, the ASC became FASB's officially recognized source of authoritative U.S. generally accepted accounting principles (GAAP) applicable to all public and non-public non-governmental entities, superseding existing FASB, American Institute of Certified Public Accountants (AICPA), Emerging Issues Task Force (EITF) and related literature. Rules and interpretive releases of the Securities and Exchange Commission (SEC) under the authority of federal securities laws are also sources of authoritative GAAP for SEC registrants. All other accounting literature is considered non-authoritative.
Basis of Presentation and Principles of Consolidation
The accounting and reporting policies of the Corporation and its subsidiaries conform to GAAP, SEC rules and interpretive releases and prevailing practices within the banking industry. The consolidated financial statements of the Corporation include the accounts of the Corporation and its wholly owned subsidiaries. All significant income and expenses are recorded on the accrual basis. Intercompany accounts and transactions have been eliminated in preparing the consolidated financial statements.
Use of Estimates
Management makes estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying footnotes. Estimates that are particularly susceptible to significant change include the determination of the allowance for loan losses, expected cash flows from acquired loans, fair value amounts related to business combinations, pension expense, income taxes, goodwill impairment and those assets that require fair value measurement. Actual results could differ from these estimates.
Business Combinations
Pursuant to the guidance of ASC Topic 805, Business Combinations (ASC 805), the Corporation recognizes assets acquired, including identified intangible assets, and the liabilities assumed in acquisitions at their fair values as of the acquisition date, with the acquisition-related transaction and restructuring costs expensed in the period incurred.
On May 31, 2015, the Corporation acquired all of the outstanding stock of Lake Michigan for total consideration of $187.4 million, which included stock consideration of $132.9 million and cash consideration of $54.5 million. The Corporation recorded $102 million of goodwill in conjunction with the acquisition, which represented the purchase price over the fair value of identifiable net assets acquired. Additionally, the Corporation recorded $8.6 million of core deposit and other intangible assets in conjunction with the acquisition.
On April 1, 2015, the Corporation acquired all of the outstanding stock of Monarch in an all-stock transaction valued at $27.2 million. The Corporation recorded $5.3 million of goodwill in conjunction with the acquisition, which represented the purchase price over the fair value of identifiable net assets acquired. Additionally, the Corporation recorded $1.9 million of core deposit intangible assets in conjunction with the acquisition.

70

On October 31, 2014, the Corporation acquired all of the outstanding stock of Northwestern Bancorp, Inc. (Northwestern) for total cash consideration of $121.0 million. The Corporation recorded $60.3 million of goodwill in conjunction with the acquisition, which represented the purchase price over the fair value of the identifiable net assets acquired. Additionally, the Corporation recorded $12.9 million of core deposit intangible assets in conjunction with the acquisition.
On December 7, 2012, Chemical Bank acquired 21 branches from Independent Bank, a subsidiary of Independent Bank Corporation (branch acquisition transaction). In connection with the branch acquisition transaction, the Corporation recorded $6.8 million of goodwill, which represented the purchase price over the fair value of identifiable net assets acquired, and $5.6 million of core deposit intangible assets.
On April 30, 2010, the Corporation acquired all of the outstanding stock of O.A.K. Financial Corporation (OAK) for total consideration of $83.7 million. The Corporation recorded $43.5 million of goodwill in conjunction with the acquisition, which represented the purchase price over the fair values of the identifiable net assets acquired. Additionally, the Corporation recorded $9.8 million of other intangible assets as a result of the OAK acquisition attributable to core deposits, mortgage servicing rights and non-compete agreements acquired.
See Note 2 for further information regarding the Corporation's mergers and acquisitions, including its pending merger with Talmer Bancorp, Inc. (Talmer).
ASC 805 affords a measurement period beyond the acquisition date that allows the Corporation the opportunity to finalize the acquisition accounting in the event that new information is identified that existed as of the acquisition date but was not known by the Corporation at that time. The Corporation anticipates that measurement period adjustments may arise from adjustments to the fair values of assets and liabilities recognized at the acquisition date for Lake Michigan and Monarch as additional information is obtained, such as appraisals of collateral securing loans and other borrower information. In the event that a measurement period adjustment is identified, the Corporation will recognize the adjustment as part of its acquisition accounting, which may result in an adjustment to goodwill being recorded in the period the adjustment was identified.
Cash and Cash Equivalents
For purposes of reporting cash flows, cash and cash equivalents include cash on hand and interest-bearing deposits held at the Federal Reserve Bank (FRB).
Investment Securities
Investment securities include investments in debt, trust preferred and preferred stock securities. Investment securities are accounted for in accordance with ASC Topic 320, Investments — Debt and Equity Securities (ASC 320), which requires investments to be classified within one of three categories (trading, held-to-maturity or available-for-sale). The Corporation held no trading investment securities at December 31, 2015 or 2014.
Designation as an investment security held-to-maturity is based on the Corporation's intent and ability to hold the security to maturity. Investment securities held-to-maturity are stated at cost, adjusted for purchase price premiums and discounts. Investment securities that are not held-to-maturity are accounted for as securities available-for-sale, and are stated at estimated fair value, with the aggregate unrealized gains and losses, not deemed other-than-temporary, classified as a component of accumulated other comprehensive income (loss), net of income taxes. Realized gains and losses on the sale of investment securities and other-than-temporary impairment (OTTI) charges are determined using the specific identification method and are included within noninterest income in the consolidated statements of income. Premiums and discounts on investment securities are amortized over the estimated lives of the related investment securities based on the effective interest yield method and are included in interest income in the consolidated statements of income.
The Corporation assesses equity and debt securities that have fair values below amortized cost basis to determine whether declines (impairment) are other-than-temporary. If the Corporation intends to sell an impaired security or it is more-likely-than-not that the Corporation will be required to sell an impaired security prior to the recovery of its amortized cost, an OTTI write-down is recognized in earnings equal to the entire difference between the security's amortized cost basis and its fair value. If the Corporation does not intend to sell an impaired security and it is not more-likely-than-not that the Corporation would be required to sell an impaired security before the recovery of its amortized cost basis, then the recognition of the impairment is bifurcated if a credit loss is deemed to have occurred. For a security where the impairment is bifurcated, the impairment is separated into an amount representing the credit loss, which is recognized in earnings, and an amount related to all other factors, which is recognized in other comprehensive income. In assessing whether OTTI exists, management considers, among other things, (i) the length of time and the extent to which the fair value has been less than cost, (ii) the financial condition and near-term prospects of the issuer, (iii) the potential for impairments in an entire industry or sub-sector and (iv) the potential for impairments in certain economically depressed geographical locations.

71

Nonmarketable Equity Securities
The Corporation is required to hold non-marketable equity securities, comprised of Federal Home Loan Bank of Indianapolis (FHLB) and FRB stock, as a condition of membership. These securities are accounted for at cost, which equals par or redemption value. These securities do not have a readily determinable fair value as their ownership is restricted and there is no market for these securities. These securities can only be redeemed or sold at their par value and only to the respective issuing government supported institution or to another member institution. FHLB stock can only be redeemed upon giving five-years written notice and FRB stock can only be redeemed upon giving six months written notice, with no more than 25% eligible for redemption in any calendar year. The Corporation records these non-marketable equity securities as a component of other assets and they are periodically evaluated for impairment. Management considers these non-marketable equity securities to be long-term investments. Accordingly, when evaluating these securities for impairment, management considers the ultimate recoverability of the par value rather than recognizing temporary declines in value, if applicable. The Corporation's ownership of FHLB stock totaled $23.9 million at December 31, 2015 and $19.0 million at December 31, 2014. The Corporation's ownership of FRB stock totaled $13.0 million at December 31, 2015 and $8.4 million at December 31, 2014.
Originated Loans
Originated loans include all of the Corporation's portfolio loans, excluding loans acquired on May 31, 2015 in the acquisition of Lake Michigan, on April 1, 2015 in the acquisition of Monarch, on October 31, 2014 in the acquisition of Northwestern and on April 30, 2010 in the acquisition of OAK. Originated loans also include loans acquired as part of the branch acquisition transaction on December 7, 2012, as these loans were performing and were considered high-quality loans in accordance with the Corporation's credit underwriting standards at that date. Originated loans are held for investment purposes and are stated at their principal amount outstanding, net of unearned income, charge-offs and unamortized deferred fees and costs. Loan interest income is recognized on the accrual basis. Deferred loan fees and costs are amortized over the loan term based on the level-yield method. Net loan commitment fees are deferred and amortized into fee income on a straight-line basis over the commitment period.
The past due status of a loan is based on the loan's contractual terms. A loan is placed in nonaccrual status (accrual of interest is discontinued) when principal or interest is past due 90 days or more (except for a loan that is secured by residential real estate, which is transferred to nonaccrual status at 120 days past due), unless the loan is both well-secured and in the process of collection, or earlier when, in the opinion of management, there is sufficient reason to doubt the collectibility of principal or interest. Interest previously accrued, but not collected, is reversed and charged against interest income at the time the loan is placed in nonaccrual status. Subsequent receipts of interest while a loan is in nonaccrual status are recorded as a reduction of principal. Loans are returned to accrual status when principal and interest payments are brought current, payments have been received consistently for a period of time (generally six months) and collectibility is no longer in doubt.
Loans Acquired in a Business Combination
Loans acquired in a business combination (acquired loans) consist of loans acquired on May 31, 2015 in the acquisition of Lake Michigan, on April 1, 2015 in the acquisition of Monarch, on October 31, 2014 in the acquisition of Northwestern and on April 30, 2010 in the acquisition of OAK. Acquired loans were recorded at fair value at the date of acquisition, without a carryover of the associated allowance for loan losses related to these loans, through a fair value discount that was, in part, attributable to deterioration in credit quality. The estimate of expected credit losses was determined based on due diligence performed by executive and senior officers of the Corporation, with assistance from third-party consultants. The fair value discount was recorded as a reduction of the acquired loans' outstanding principal balances in the consolidated statement of financial position at the acquisition date.
The Corporation accounts for acquired loans, which are recorded at fair value at acquisition, in accordance with ASC Topic 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality (ASC 310-30). Under the provisions of ASC 310-30, the Corporation aggregated acquired loans with an outstanding principal balance at the acquisition date of $63 million for the Lake Michigan transaction, $9 million for the Monarch transaction, $46 million for the Northwestern transaction and $105 million for the OAK transaction that were determined to be loans with deteriorated credit quality and, therefore, met the scope criteria set forth in ASC 310-30. Further, the Corporation understands, as outlined in the AICPA's open letter to the Office of the Chief Accountant of the SEC dated December 18, 2009 and pending further standard setting, that for acquired loans that do not meet the scope criteria of ASC 310-30, a company may elect to account for such acquired loans pursuant to the provisions of either ASC Topic 310-20, Nonrefundable Fees and Other Costs, or ASC 310-30. The Corporation elected to apply ASC 310-30, by analogy, to acquired loans that were determined not to have deteriorated credit quality with an outstanding principal balance at the acquisition date of $947 million for the Lake Michigan transaction, $120 million for the Monarch transaction, $461 million for the Northwestern transaction and $578 million for the OAK transaction and thus follows the accounting and disclosure guidance of ASC 310-30 for these loans. Accordingly, the Corporation applied ASC 310-30 to the entire loan portfolio acquired with a total outstanding principal balance at the acquisition date of $1.01 billion for the Lake Michigan transaction, $129 million for the Monarch transaction, $507 million for the Northwestern transaction and $683 million for the OAK transaction. None of the acquired loans were classified as debt securities.

72

ASC 310-30 allows investors to aggregate acquired loans into loan pools that have common risk characteristics and thereby use a composite interest rate and expectation of cash flows expected to be collected for the loan pools. Under the provisions of ASC 310-30, the Corporation aggregated acquired loans into 2 pools in the acquisition of Lake Michigan, 2 pools in the acquisition of Monarch, 4 pools in the acquisition of Northwestern and 14 pools in the acquisition of OAK based upon common risk characteristics, including types of loans, commercial type loans with similar risk grades and whether loans were performing or nonperforming. A pool is considered a single unit of accounting for the purposes of applying the guidance prescribed in ASC 310-30. A loan will be removed from a pool of acquired loans only if the loan is sold, foreclosed, paid off or written off, and will be removed from the pool at the carrying value. If an individual loan is removed from a pool of loans, the difference between its relative carrying amount and the cash, fair value of the collateral, or other assets received would not affect the effective yield used to recognize the accretable difference on the remaining pool. The Corporation estimated the cash flows expected to be collected over the life of the pools of loans at acquisition and estimates expected cash flows quarterly thereafter, based on a set of assumptions including expectations as to default rates, prepayment rates and loss severities. The Corporation must make numerous assumptions, interpretations and judgments using internal and third-party credit quality information to determine whether it is probable that the Corporation will be able to collect all contractually required payments. This is a point in time assessment and inherently subjective due to the nature of the available information and judgment involved.
The calculation of the fair value of the acquired loan pools entails estimating the amount and timing of cash flows attributable to both principal and interest expected to be collected on such loan pools and then discounting those cash flows at market interest rates. The excess of a loan pool's expected cash flows at the acquisition date over its estimated fair value is referred to as the "accretable yield," which is recognized into interest income over the remaining life of the loan on a level-yield basis. The difference between a loan pool's contractually required principal and interest payments at the acquisition date and the cash flows expected to be collected at the acquisition date is referred to as the "nonaccretable difference," which includes an estimate of future credit losses expected to be incurred over the estimated life of the loan pool and interest payments that are not expected to be collected. Decreases to the expected cash flows in each loan pool in subsequent periods will require the Corporation to record a provision for loan losses. Improvements in expected cash flows in each loan pool in subsequent periods will result in reversing a portion of the nonaccretable difference, which is then classified as part of the accretable yield and subsequently recognized into interest income over the estimated remaining life of the loan pool.
Loans Modified Under Troubled Debt Restructurings
Loans modified under troubled debt restructurings (TDRs) involve granting a concession to a borrower who is experiencing financial difficulty. Concessions generally include modifications to original loan terms, including changes to a loan's payment schedule or interest rate, which generally would not otherwise be considered. The Corporation's TDRs include performing and nonperforming TDRs, which consist of originated loans that continue to accrue interest at the loan's original interest rate as the Corporation expects to collect the remaining principal and interest on the loan, and nonaccrual TDRs, which include originated loans that are in a nonaccrual status and are no longer accruing interest, as the Corporation does not expect to collect the full amount of principal and interest owed from the borrower on these loans. At the time of modification (except for loans on nonaccrual status), a TDR is classified as a nonperforming TDR until a six-month payment history of principal and interest payments, in accordance with the terms of the loan modification, is sustained, at which time the Corporation moves the loan to a performing status (performing TDR). If the Corporation does not expect to collect all principal and interest on the loan, the modified loan is classified as a nonaccrual TDR. All TDRs are accounted for as impaired loans and are included in the Corporation's analysis of the allowance for loan losses. A TDR that has been renewed for a borrower who is no longer experiencing financial difficulty and which yields a market rate of interest at the time of a renewal is no longer considered to be a TDR.
Loans in the Corporation's commercial loan portfolio (comprised of commercial, commercial real estate, real estate construction and land development loans) that meet the definition of a TDR generally consist of loans where the Corporation has allowed borrowers to defer scheduled principal payments and make interest-only payments for a specified period of time at the stated interest rate of the original loan agreement or reduced payments due to a moderate extension of the loan's contractual term. If the Corporation does not expect to collect all principal and interest on the loan, the modified loan is classified as a nonaccrual TDR. If the Corporation does not expect to incur a loss on the loan based on its assessment of the borrowers' expected cash flows, as the pre- and post-modification effective yields are approximately the same, the loan is classified as a nonperforming TDR until a six-month payment history is sustained, at which time the loan is classified as a performing TDR. Since no loss is expected to be incurred on these loans, no additional provision for loan losses has been recognized related to these loans, and these loans accrue interest at their contractual interest rate. These loans are individually evaluated for impairment and transferred to nonaccrual status if they become 90 days past due as to principal or interest payments or if it is probable that any remaining principal and interest payments due on the loan will not be collected in accordance with the modified terms of the loan.
Loans in the Corporation's consumer loan portfolio (comprised of residential mortgage, consumer installment and home equity loans) that meet the definition of a performing or nonperforming TDR generally consist of residential mortgage loans that include a concession that reduces a borrower's monthly payments by decreasing the interest rate charged on the loan for a specified period of time (generally 24 months) under a formal modification agreement. The Corporation recognizes an additional provision for

73

loan losses related to impairment on these loans on an individual basis based on the present value of expected future cash flows discounted at the loan's original effective interest rate. These loans continue to accrue interest at their effective interest rate, which consists of contractual interest under the terms of the modification agreement in addition to an adjustment for the accretion of computed impairment. These loans are moved to nonaccrual status if they become 90 days past due as to principal or interest payments, or sooner if conditions warrant.
Impaired Loans
A loan is defined to be impaired when it is probable that payment of principal and interest will not be paid in accordance with the original contractual terms of the loan agreement. Impaired loans include nonaccrual loans (including nonaccrual TDRs), performing and nonperforming TDRs and acquired loans that were not performing in accordance with original contractual terms. Impaired loans are accounted for at the lower of the present value of expected cash flows discounted at the loan's original effective interest rate or the estimated fair value of the collateral, if the loan is collateral dependent. When the present value of expected cash flows or the fair value of collateral of an impaired loan in the originated loan portfolio is less than the amount of unpaid principal outstanding on the loan, the principal balance of the loan is reduced to its carrying value through either an allocation of the allowance for loan losses or a partial charge-off of the loan balance.
Nonperforming Loans
Nonperforming loans are comprised of loans for which the accrual of interest has been discontinued (nonaccrual loans, including nonaccrual TDRs), accruing originated loans contractually past due 90 days or more as to interest or principal payments and nonperforming TDRs.
Acquired loans that were classified as nonperforming loans prior to being acquired and acquired loans that are not performing in accordance with contractual terms subsequent to acquisition are not classified as nonperforming loans subsequent to acquisition because the loans are recorded in pools at net realizable value based on the principal and interest the Corporation expects to collect on such loans.
Allowance for Loan Losses
The allowance for loan losses (allowance) is presented as a reserve against loans. The allowance represents management's assessment of probable loan losses inherent in the Corporation's loan portfolio.
Management's evaluation of the adequacy of the allowance is based on a continuing review of the loan portfolio, actual loan loss experience, the underlying value of the collateral, risk characteristics of the loan portfolio, the level and composition of nonperforming loans, the financial condition of the borrowers, the balance of the loan portfolio, loan growth, economic conditions, employment levels in the Corporation's local markets and special factors affecting specific business sectors. The Corporation maintains formal policies and procedures to monitor and control credit risk. Management evaluates the allowance on a quarterly basis in an effort to ensure the level is appropriate to absorb probable losses inherent in the loan portfolio.
The allowance provides for probable losses that have been identified with specific customer relationships and for probable losses believed to be incurred in the remainder of the originated loan portfolio, but that have not been specifically identified. The Corporation utilizes its own loss experience to estimate inherent losses on loans. Internal risk ratings are assigned to each loan in the commercial loan portfolio (commercial, commercial real estate, real estate construction and land development loans) at the time of origination and are subject to subsequent periodic reviews by senior management. The Corporation performs a detailed credit quality review quarterly on all loans greater than $0.25 million that have deteriorated below certain levels of credit risk, and may allocate a specific portion of the allowance to such loans based upon this review. A portion of the allowance is allocated to the remaining loans by applying projected loss ratios, based on numerous factors. Projected loss ratios incorporate factors such as recent charge-off experience, trends with respect to adversely risk-rated loans in the commercial loan portfolio, trends with respect to past due and nonaccrual loans, changes in economic conditions and trends, changes in the value of underlying collateral and other credit risk factors. This evaluation involves a high degree of uncertainty.
In determining the allowance and the related provision for loan losses, the Corporation considers four principal elements: (i) valuation allowances based upon probable losses identified during the review of impaired loans in the commercial loan portfolio, (ii) reserves established for adversely-rated loans in the commercial loan portfolio and nonaccrual residential mortgage, consumer installment and home equity loans based on loan loss experience of other adversely-rated loans, (iii) reserves, by loan classes, on all other loans based principally on a five-year historical loan loss experience, loan loss trends and giving consideration to estimated loss emergence periods and (iv) a reserve for qualitative factors that take into consideration risks inherent in the originated loan portfolio that differ from historical loan loss experience.
The first element reflects the Corporation's estimate of probable losses based upon the systematic review of individually impaired loans in the originated commercial loan portfolio. These estimates are based upon a number of objective factors, such as payment history, financial condition of the borrower and discounted collateral exposure. The Corporation measures the investment in an

74

impaired loan based on one of three methods: the loan's observable market price; the fair value of the collateral; or the present value of expected future cash flows discounted at the loan's effective interest rate. Loans in the commercial loan portfolio that were in nonaccrual status (including nonaccrual TDRs) were valued based on the fair value of the collateral securing the loan, while performing and nonperforming TDRs in the commercial loan portfolio were valued based on the present value of expected future cash flows discounted at the loan's effective interest rate. It is the Corporation's general policy to obtain new appraisals at least annually on nonaccrual loans in the commercial loan portfolio and at least every other year on nonperforming TDRs in the commercial loan portfolio that are primarily secured by real estate and have a loan balance of greater than $0.25 million. When the Corporation determines that the fair value of the collateral is less than the carrying value of an impaired loan on nonaccrual status and a portion is deemed not collectible, the portion of the impairment that is deemed not collectible is charged off (confirmed loss) and deducted from the allowance. The remaining carrying value of the impaired loan is classified as a nonperforming loan. When the Corporation determines that the fair value of the collateral is less than the carrying value of an impaired loan but believes it is probable it will recover this impairment, the Corporation establishes a valuation allowance for such impairment.
The second element reflects the application of the Corporation's loan grade risk rating system. This risk rating system is similar to those employed by state and federal banking regulators. Loans in the commercial loan portfolio that are risk rated below a certain predetermined risk grade and nonaccrual residential mortgage, consumer installment and home equity loans are assigned a loss allocation factor that is based upon a historical analysis of actual loan losses incurred and a valuation of the type of collateral securing the loans.
The third element is determined by assigning allocations based principally upon a weighted five-year average of loss experience for each class of loan with higher weighting placed on the most recent years. Average losses may be adjusted based on current loan loss experience, delinquency trends, estimated loss emergence periods and other environmental factors. This component considers the lagging impact of historical charge-off ratios in periods where future loan charge-offs are expected to increase or decrease, trends in delinquencies and nonaccrual loans, the changing portfolio mix in terms of collateral, average loan balance, loan growth and the degree of seasoning in the various loan portfolios. Loan loss analyses are performed quarterly and certain inputs and parameters are updated as necessary to reflect the current credit environment.
The fourth element is based on qualitative factors that cannot be associated with a specific credit or loan class and reflects an attempt to ensure that the overall allowance appropriately reflects additional losses that are inherent in the Corporation's loan portfolio. Determination of the probable losses inherent in the portfolio, which are not necessarily captured by the allocation methodology discussed above, involves the exercise of judgment. This qualitative portion of the allowance is judgmentally determined and generally serves to compensate for the uncertainty in estimating inherent losses, particularly in times of changing economic conditions, and also considers the inherent judgment associated with risk rating commercial loans. The qualitative portion of the allowance also takes into consideration, among other things, economic conditions within the State of Michigan and nationwide, including unemployment levels, industry-wide and Corporation specific loan delinquency rates, changes in composition of and growth in the Corporation's loan portfolio, changing commercial and residential real estate values and inventory levels of residential lots, condominiums and single family houses held for sale.
Although the Corporation allocates portions of the allowance to specific loans and loan types, the entire allowance attributable to originated loans is available for any loan losses that occur in the originated portfolio. Loans that are deemed not collectible are charged off and reduce the allowance. The provision for loan losses and recoveries on loans previously charged off increase the allowance. Collection efforts may continue and recoveries may occur after a loan is charged off.
Acquired loans are aggregated into pools based upon common risk characteristics. An allowance may be recorded related to an acquired loan pool if it experiences a decrease in expected cash flows, as compared to those projected at the acquisition date. On a quarterly basis, the expected future cash flow of each pool is estimated based on various factors, including changes in property values of collateral dependent loans, default rates, loss severities and prepayment speeds. Decreases in estimates of expected cash flows within a pool generally result in a charge to the provision for loan losses and a corresponding increase in the allowance allocated to acquired loans for the particular pool. Increases in estimates of expected cash flows within a pool generally result in a reduction in the allowance allocated to acquired loans for the particular pool, if applicable, and then an adjustment to the accretable yield for the pool, which will increase amounts recognized in interest income in subsequent periods.
Various regulatory agencies, as an integral part of their examination processes, periodically review the allowance. Such agencies may require additions to the allowance, based on their judgment, reflecting information available to them at the time of their examinations.
Mortgage Banking Operations
The origination of residential mortgage loans is an integral component of the business of the Corporation. The Corporation generally sells conforming long-term fixed interest rate mortgage loans it originates in the secondary market. Gains on the sales of these loans are determined using the specific identification method. The Corporation sells residential mortgage loans in the secondary market on either a servicing retained or released basis.

75

The Corporation elected the fair value measurement option, as prescribed by ASC Topic 820, Fair Value Measurements and Disclosures (ASC 820), for all residential mortgage loans held-for-sale originated on or after July 1, 2012. This election allows for a more effective offset of the changes in fair value of residential mortgage loans held-for-sale and the derivative instruments used to economically hedge them without having to apply complex hedge accounting provisions. Residential mortgage loans held-for-sale are carried at fair value, with changes in fair value recorded through earnings. The value of mortgage loans held-for-sale and other residential mortgage loan commitments to customers are hedged by utilizing best efforts forward commitments to sell loans to investors in the secondary market. Such forward commitments are generally entered into at the time customer applications are accepted to protect the value of the mortgage loans from increases in market interest rates during the period held and are generally settled with the investor in the secondary market within 90 days after entering into the forward commitment.
Forward loan commitments are accounted for as derivatives and recorded at fair value, with changes in fair value recorded through earnings. The Corporation recognizes revenue associated with the expected future cash flows of servicing loans for loans held-for-sale at the time a forward loan commitment is made to originate a held-for-sale loan, as required under SEC Staff Accounting Bulletin No. 109, Written Loan Commitments Recorded at Fair Value Through Earnings.
The Corporation accounts for mortgage servicing rights (MSRs) by separately recognizing servicing assets at the date of sale. An asset is recognized for the rights to service mortgage loans that are created by the origination of mortgage loans that are sold with the servicing retained by the Corporation. The Corporation's MSRs are included in other intangible assets in the statement of financial condition. The Corporation measures its MSRs at the lower of amortized cost or fair value and amortizes MSRs in proportion to and over the period of net servicing income. Unexpected prepayments of mortgage loans result in increased amortization of MSRs, as the remaining book value of the MSRs is expensed at the time of prepayment. The Corporation assesses MSRs for impairment on a quarterly basis based on fair value measurements. For purposes of measuring impairment, MSRs are stratified into relatively homogeneous pools based on characteristics such as period of origination, maturity date and interest rates. MSRs are also stratified between servicing assets originated by the Corporation and those acquired in acquisitions of other institutions. Any temporary impairment of MSRs is recognized as a valuation allowance, resulting in a reduction of mortgage banking revenue. The valuation allowance is recovered when impairment that is believed to be temporary no longer exists. Other-than-temporary impairments are recognized if the recoverability of the carrying value is determined to be remote. When this occurs, the unrecoverable portion of the valuation allowance is recorded as a direct write-down to the carrying value of MSRs. This direct write-down permanently reduces the carrying value of the MSRs, precluding recognition of subsequent recoveries, and results in a reduction of mortgage banking revenue. For purposes of measuring the fair value of MSRs, the Corporation utilizes a third-party modeling software program which is periodically validated by using valuations received from third-party valuation specialists. Servicing income is recognized when earned and is offset by the amortization of MSRs.
Premises and Equipment
Land is recorded at cost. Premises and equipment are stated at cost less accumulated depreciation. Premises and equipment are depreciated over the estimated useful lives of the assets. The estimated useful lives are generally 25 to 40 years for buildings and three to ten years for all other depreciable assets. Depreciation is computed on the straight-line method. Maintenance and repairs are charged to expense as incurred.
Other Real Estate
Other real estate (ORE) is primarily comprised of commercial and residential real estate properties, including vacant land and development properties, obtained in partial or total satisfaction of loan obligations. ORE also includes closed branch offices that are held for sale. ORE is recorded at the lower of cost or the estimated fair value of the property, less anticipated selling costs, based upon the property's appraised value at the date of transfer to ORE and management's estimate of the fair value of the collateral, with any difference between the net realizable value of the property and the carrying value of the loan charged to the allowance for loan losses. Subsequent changes in the fair value of ORE are recognized as adjustments to the carrying amount, not to exceed the initial carrying value of the assets at the time of transfer. Changes in the fair value of ORE, subsequent to the initial transfer to ORE, and costs incurred to maintain ORE are recorded in other operating expenses on the consolidated statements of income. Gains or losses resulting from the sale of ORE are also recognized in other operating expenses on the date of sale. ORE totaling $12.7 million and $14.8 million at December 31, 2015 and 2014, respectively, was included in the consolidated statements of financial position in interest receivable and other assets. ORE at December 31, 2015 and 2014 included $3.0 million and $0.9 million, respectively, related to closed branch offices.
Goodwill
Goodwill is not amortized, but rather is subject to impairment tests annually, or more frequently if triggering events occur and indicate potential impairment. The Corporation's annual goodwill impairment assessment was performed as of October 31, 2015. The Corporation elected to utilize the qualitative assessment of goodwill impairment allowed under ASC Topic 350-20, Goodwill (ASC 350-20) that became acceptable as a result of FASB Accounting Standards Update (ASU) 2011-08, Testing Goodwill for

76

Impairment. In accordance with ASC 350-20, the Corporation assessed qualitative factors to determine whether it is more likely than not that the fair value of its reporting units were less than their carrying amounts.
In evaluating whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the Corporation assesses relevant events and circumstances, including macroeconomic conditions, industry and market considerations, overall financial performance, changes in the composition or carrying amount of assets and liabilities, the market price of the Corporation's common stock, and other relevant factors. Based on the qualitative assessment performed, the Corporation determined that no goodwill impairment was evident as of the October 31, 2015 assessment date. The Corporation also determined that no triggering events occurred that indicated impairment from the most recent assessment date through December 31, 2015 and that the Corporation's goodwill was not impaired at December 31, 2015.
Other Intangible Assets
Intangible assets consist of core deposit intangible assets, non-compete intangible assets and MSRs. Core deposit intangible assets arose as the result of business combinations or other acquisitions and are amortized over periods ranging from 10 to 15 years, primarily on an accelerated basis, as applicable. Non-compete intangible assets arose as the result of business combinations and are amortized over the period of the non-compete agreements. Intangible assets are tested for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable from future undiscounted cash flows.
Share-based Compensation
The Corporation grants stock options, stock awards, restricted stock performance units and restricted stock service-based units to certain executive and senior management employees. The Corporation accounts for share-based compensation expense using the modified-prospective transition method. Under that method, compensation expense is recognized for stock options based on the estimated grant date fair value as computed using the Black-Scholes option pricing model and the probability of issuance. The Corporation accounts for stock awards based on the closing stock price of the Corporation's common stock on the date of the award. The fair values of both stock options and stock awards are recognized as compensation expense on a straight-line basis over the requisite service period. Compensation expense is adjusted to reflect actual forfeitures at the time they occur. The Corporation accounts for restricted stock performance units based on the closing stock price of the Corporation's common stock on the date of grant, discounted by the present value of estimated future dividends to be declared over the requisite performance or service period. The fair value of restricted stock performance units is recognized as compensation expense over the expected requisite performance period, or requisite service period for awards with multiple performance and service conditions. The Corporation accounts for restricted stock service-based units based on the closing stock price of the Corporation's common stock on the date of grant, as these awards accrue dividend equivalents equal to the amount of any cash dividends that would have been payable to a shareholder owning the number of shares of the Corporation's common stock represented by the restricted stock service-based units. The fair value of the restricted stock service-based units is recognized as compensation expense over the requisite service period.
Cash flows realized from the tax benefits of exercised stock option awards that result from actual tax deductions that are in excess of the recorded tax benefits related to the compensation expense recognized for those options (excess tax benefits) are classified as financing activities on the consolidated statements of cash flows.
Bank-Owned Life Insurance
The Corporation has life insurance policies on certain key officers of its bank subsidiaries. The majority of the bank-owned life insurance policies of the Corporation were obtained through its acquisition of Lake Michigan. Bank-owned life insurance is recorded at the cash surrender value, net of surrender charges, and is included within other assets on the consolidated statements of financial position and changes in the cash surrender values are recorded as other noninterest income on the consolidated statements of income.
Short-term Borrowings
Short-term borrowings are comprised of securities sold under agreements to repurchase with customers, federal funds purchased and short-term FHLB advances with original scheduled maturities of one year or less. Securities sold under agreements to repurchase with customers are collateralized financing transactions and the obligations to repurchase securities sold are reflected as a liability in the accompanying consolidated statements of financial position. The dollar amount of the securities underlying the agreements remain in the Corporation's investment securities portfolio. The Corporation's securities sold under agreements to repurchase with customers are considered a stable source of liquidity, much like its core deposit base, and are generally only provided to customers that have an established banking relationship with Chemical Bank. Federal funds purchased represent unsecured borrowings from nonaffiliated third-party financial institutions, generally on an overnight basis, to cover short-term liquidity needs.

77

Other Borrowings
Other borrowings are comprised of securities sold under agreements with an unaffiliated third-party financial institution, a secured non-revolving line-of-credit with an unaffiliated third-party financial institution, subordinated debentures and long-term FHLB advances. Securities sold under agreements to repurchase are collateralized financing transactions and the obligations to repurchase securities sold are reflected as a liability in the accompanying consolidated statements of financial position. The dollar amount of the securities underlying the agreements remain in the Corporation's investment securities portfolio.
FHLB advances, both short-term and long-term, are borrowings from the FHLB to fund short-term liquidity needs as well as a portion of the loan and investment securities portfolios. These advances are secured, under a blanket security agreement, by first lien residential mortgage loans with an aggregate book value equal to at least 140% of the FHLB advances and the FHLB stock owned by the Corporation. FHLB advances with an original maturity of one year or less are classified as short-term and FHLB advances with an original maturity of more than one year are classified as long-term.
Fair Value Measurements
Fair value for assets and liabilities measured at fair value on a recurring or nonrecurring basis refers to the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants in the market in which the reporting entity transacts such sales or transfers based on the assumptions market participants would use when pricing an asset or liability. Assumptions are developed based on prioritizing information within a fair value hierarchy that gives the highest priority to quoted prices in active markets and the lowest priority to unobservable data, such as the reporting entity's own data.
The Corporation may choose to measure eligible items at fair value at specified election dates. Unrealized gains and losses on items for which the fair value measurement option has been elected are reported in earnings at each subsequent reporting date. The fair value option (i) may be applied instrument by instrument, with certain exceptions, allowing the Corporation to record identical financial assets and liabilities at fair value or by another measurement basis permitted under GAAP, (ii) is irrevocable (unless a new election date occurs) and (iii) is applied only to entire instruments and not to portions of instruments. At December 31, 2015 and 2014, the Corporation had elected the fair value option on all of its residential mortgage loans held-for-sale. The Corporation has not elected the fair value option for any other financial assets or liabilities.
Pension and Postretirement Benefit Plan Actuarial Assumptions
The Corporation's defined benefit pension, supplemental pension and postretirement benefit obligations and related costs are calculated using actuarial concepts and measurements. Two critical assumptions, the discount rate and the expected long-term rate of return on plan assets, are important elements of expense and/or benefit obligation measurements. Other assumptions involve employee demographic factors such as retirement patterns, mortality, turnover and the rate of future compensation increases, as well as future health care costs. The Corporation evaluates all assumptions annually. Mortality assumptions at December 31, 2015 were based on the RP-2014 mortality tables, as prescribed by the Pension Protection Act of 2006, using the MP-2015 mortality improvement scale. Mortality assumptions at December 31, 2014 were based on the RP-2014 mortality tables using the MP-2014 mortality improvement scale.
The discount rate enables the Corporation to state expected future benefit payments as a present value on the measurement date. The Corporation determined the discount rate at December 31, 2015 and 2014 by utilizing the results from a discount rate model that involves selecting a portfolio of bonds to settle the projected benefit payments of each plan. The selected bond portfolios are derived from a universe of corporate bonds rated at Aa quality. After a bond portfolio is selected, a single rate is determined that equates the market value of the bonds purchased to the discounted value of the plan's benefit payments which represents the discount rate. A lower discount rate increases the present value of benefit obligations and increases pension, supplemental pension and postretirement benefit expenses.
To determine the expected long-term rate of return on defined benefit pension plan assets, the Corporation considers the current asset allocation of the defined benefit pension plan, as well as historical and expected returns on each asset class. A lower expected rate of return on defined benefit pension plan assets will increase pension expense.
The Corporation recognizes the over- or under-funded status of a plan as an other asset or other liability in the consolidated statements of financial position as measured by the difference between the fair value of the plan assets and the projected benefit obligation. Unrecognized prior service costs and actuarial gains and losses are recognized as a component of accumulated other comprehensive income (loss). The Corporation measures defined benefit plan assets and obligations as of December 31.
Advertising Costs
Advertising costs are expensed as incurred.

78

Income and Other Taxes
The Corporation is subject to the income and other tax laws of the United States, the State of Michigan and other states where nexus has been created. These laws are complex and are subject to different interpretations by the taxpayer and the various taxing authorities. In determining the provision for income and other taxes, management must make judgments and estimates about the application of these inherently complex laws, related regulations and case law. In the process of preparing the Corporation's tax returns, management attempts to make reasonable interpretations of enacted tax laws. These interpretations are subject to challenge by the tax authorities upon audit or to reinterpretation based on management's ongoing assessment of facts and evolving case law.
The Corporation and its subsidiaries file a consolidated federal income tax return. The provision for federal income taxes is based on income and expenses, as reported in the consolidated financial statements, rather than amounts reported on the Corporation's federal income tax return. The difference between the federal statutory income tax rate and the Corporation's effective federal income tax rate is primarily a function of the proportion of the Corporation's interest income exempt from federal taxation, nondeductible interest expense and other nondeductible expenses relative to pretax income and tax credits. When income and expenses are recognized in different periods for tax purposes than for book purposes, deferred tax assets and liabilities are recognized for the future tax consequences attributable to the temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Differences in the tax and book carrying amounts of assets and liabilities can also be generated when the Corporation acquires other banks or bank branches. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized as income or expense in the period that includes the enactment date of the change.
On a quarterly basis, management assesses the reasonableness of its effective federal tax rate based upon its estimate of taxable income and the applicable taxes expected for the full year. Deferred tax assets and liabilities are reassessed on a quarterly basis, including the need for a valuation allowance for deferred tax assets.
Uncertain income tax positions are evaluated to determine whether it is more-likely-than-not that a tax position will be sustained upon examination based on the technical merits of the tax position. If a tax position is more-likely-than-not to be sustained, a tax benefit is recognized for the amount that is greater than 50% likely to be realized. Reserves for contingent income tax liabilities attributable to unrecognized tax benefits associated with uncertain tax positions are reviewed quarterly for adequacy based upon developments in tax law and the status of audits or examinations. The Corporation had no contingent income tax liabilities recorded at December 31, 2015 and 2014.
Investments in Qualified Affordable Housing Projects, Federal Historic Projects and New Market Tax Credits
The Corporation invests in qualified affordable housing projects, federal historic projects, and new market projects for the purpose of community reinvestment and obtaining tax credits. Return on the Corporation's investment in these projects comes in the form of the tax credits and tax losses that pass through to the Corporation. The carrying value of the investments are reflected in other assets on the consolidated statements of financial position. The Corporation utilizes the proportional amortization method to account for investments in qualified affordable housing projects and the equity method to account for investments in other tax credit projects.
Under the proportional amortization method, the Corporation amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits allocated. The Corporation recognized additional income tax expense attributable to the amortization of investments in qualified affordable housing projects of $1.3 million and $0.4 million during 2015 and 2014, respectively. The Corporation's remaining investment in qualified affordable housing projects accounted for under the proportional amortization method totaled $21.7 million at December 31, 2015 and $4.9 million at December 31, 2014. The increase in qualified affordable housing project investments at December 31, 2015, compared to December 31, 2014, was attributable to investments acquired as part of the Lake Michigan transaction.
Under the equity method, the Corporation's share of the earnings or losses are included in other operating expenses on the consolidated statements of income. The Corporation's investment in new market projects accounted for under the equity method totaled $1.7 million at December 31, 2015. There were no investments in such projects accounted for under the equity method as of December 31, 2014.
The Corporation's unfunded equity contributions relating to investments in qualified affordable housing projects, federal historic tax projects and new market projects is recorded in other liabilities on the consolidated statements of financial position. The Corporation's remaining unfunded equity contributions totaled $8.0 million at December 31, 2015.
Management analyzes these investments for potential impairment when events or changes in circumstances indicate that it is more-likely-than-not that the carrying amount of the investment will not be realized. An impairment loss is measured as the amount by which the carrying amount of an investment exceeds its fair value. There were no impairment losses recognized as of December 31, 2015 or 2014.

79

The Corporation consolidates variable interest entities (VIEs) in which it is the primary beneficiary. In general, a VIE is an entity that either (i) has an insufficient amount of equity to carry out its principal activities without additional subordinated financial support, (ii) has a group of equity owners that are unable to make significant decisions about its activities or (iii) has a group of equity owners that do not have the obligation to absorb losses or the right to receive returns as generated by its operations. If any of these characteristics are present, the entity is subject to a variable interests consolidation model, and consolidation is based on variable interests, not on ownership of the entity's outstanding voting stock. Variable interests are defined as contractual, ownership, or other monetary interests in an entity that change with fluctuations in the entity's net asset value. The primary beneficiary consolidates the VIE. The primary beneficiary is defined as the enterprise that has the power to direct the activities and absorb losses or the right to receive benefits. The Corporation is a significant limited partner in the qualified affordable housing, federal historic and new market projects it has invested in. These projects meet the definition of VIEs. However, the Corporation is not the primary beneficiary of any of the VIEs in which it holds a limited partnership interest; therefore, the VIEs are not consolidated in the Corporation's consolidated financial statements.
Comprehensive Income
Comprehensive income of the Corporation includes net income and adjustments to shareholders' equity for changes in unrealized gains and losses on investment securities available-for-sale and changes in the net actuarial gain/loss for the Corporation's defined benefit pension and postretirement plans, net of income taxes. The Corporation presents comprehensive income as a component in the consolidated statements of changes in shareholders' equity and the components of other comprehensive income separately in the consolidated statements of comprehensive income.
Reclassifications
Certain amounts appearing in the consolidated financial statements and notes thereto for prior periods have been reclassified to conform with the current presentation. The reclassification had no effect on net income or shareholders’ equity as previously reported.
Adopted Accounting Pronouncements
Business Combinations
In September 2015, the FASB issued ASU 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments (ASU 2015-16). ASU 2015-16 amends current guidance by requiring companies that make an acquisition to recognize adjustments to provisional amounts identified during the measurement period by calculating the adjustments as if they were known at the acquisition date, but recognizing the adjustments in the reporting period in which they occur, rather than retroactively accounting for provisional adjustments by revising prior-period information as GAAP currently requires. ASU 2015-16 also requires a company to report, either on its income statement or in a footnote disclosure, the portion of the amount that is recorded in its earnings for the current period, by line item, that would have been recorded in previous reporting periods had the adjustment to the provisional amounts been recognized as of the acquisition date. ASU 2015-16 is effective for public companies for interim and annual periods beginning after December 15, 2015, with early adoption permitted. The Corporation elected to adopt the provisions of ASU 2015-16 as of and for its quarter ended September 30, 2015. The Corporation's adoption of ASU 2015-16 in the third quarter of 2015 did not have a material impact on the Corporation's consolidated financial condition or results of operations. During the third quarter of 2015, the Corporation made adjustments to provisional amounts previously recorded related to the acquisitions of Lake Michigan, Monarch and Northwestern. Additional information regarding these adjustments is included in Note 2, Mergers and Acquisitions, to these consolidated financial statements.
In-Substance Foreclosures
In January 2014, the FASB issued ASU 2014-04, Receivables—Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure, a consensus of the FASB Emerging Issues Task Force (ASU 2014-04). ASU 2014-04 clarifies that an in-substance foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either (i) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or (ii) the borrower conveying all interest in the residential real estate property to the creditor to satisfy the loan through completion of a deed in lieu of foreclosure or similar legal agreement. ASU 2014-04 also requires disclosure of both the amount of foreclosed residential real estate property held by the creditor and the recorded investment in loans collateralized by residential real estate property that are in the process of foreclosure. ASU 2014-04 is effective for public companies for interim and annual periods beginning after December 15, 2014, with early adoption permitted. Once adopted, an entity can elect either (i) a modified retrospective transition method or (ii) a prospective transition method. The modified retrospective transition method is applied by means of a cumulative-effect adjustment to residential mortgage loans and foreclosed residential real estate properties existing as of the beginning of the period for which the amendments of ASU 2014-04 are effective, with real estate reclassified to loans measured at the carrying value of the real estate at the date of adoption and loans reclassified to real estate measured at the lower of net carrying value of

80

the loan or the fair value of the real estate less costs to sell at the date of adoption. The prospective transition method is applied by means of applying the amendments of ASU 2014-04 to all instances of receiving physical possession of residential real estate properties that occur after the date of adoption. The Corporation's adoption of ASU 2014-04 on January 1, 2015 did not have a material impact on the Corporation's consolidated financial condition or results of operations.
Share-Based Compensation
In June 2014, the FASB issued ASU 2014-12, Compensation—Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period, a consensus of the FASB Emerging Issues Task Force (ASU 2014-12). ASU 2014-12 requires that a performance target that affects vesting of share-based payment awards and that could be achieved after the requisite service period be treated as a performance condition. Compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the periods for which the requisite service has already been rendered. If the performance target becomes probable of being achieved before the end of the requisite service period, the remaining unrecognized compensation cost should be recognized prospectively over the remaining requisite service period. The total amount of compensation cost recognized during and after the requisite service period should reflect the number of awards that are expected to vest and should be adjusted to reflect those awards that ultimately vest. The requisite service period ends when the employee can cease rendering service and still be eligible to vest in the award if the performance target is achieved. ASU 2014-12 is effective for all entities for interim and annual periods beginning after December 15, 2015, with early adoption permitted. An entity may apply the amendments in ASU 2014-12 either (i) prospectively to all awards granted or modified after the effective date or (ii) retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter. The Corporation's early adoption of ASU 2014-12 on January 1, 2015 did not have a material impact on the Corporation's consolidated financial condition or results of operations.
Government-Guaranteed Mortgage Loans
In August 2014, the FASB issued ASU 2014-14, Receivables—Troubled Debt Restructurings by Creditors (Subtopic 310-40): Classification of Certain Government Guaranteed Mortgage Loans upon Foreclosure, a consensus of the FASB Emerging Issues Task Force (ASU 2014-14). ASU 2014-14 provides clarifying guidance related to how creditors classify government-guaranteed loans upon foreclosure. Upon foreclosure of a government-guaranteed mortgage loan, the loan should be derecognized and a separate other receivable should be recognized if the following conditions are met: (i) the loan has a government guarantee that is not separable from the loan before foreclosure; (ii) at the time of foreclosure, the creditor has the intent to convey the real estate property to the guarantor and make a claim on the guarantee, and the creditor has the ability to recover under that claim; and (iii) at the time of foreclosure, any amount of the claim that is determined on the basis of the fair value of the real estate is fixed. The separate other receivable should be measured based on the amount of the loan balance (principal and interest) expected to be recovered from the guarantor at the time of foreclosure. ASU 2014-14 is effective for public companies for interim and annual periods beginning after December 15, 2014. An entity should adopt ASU 2014-14 using either the modified retrospective method or the prospective transition method. An entity must apply the same method elected under ASU 2014-04. Early adoption is permitted if the entity has already adopted ASU 2014-04. The Corporation's adoption of ASU 2014-14 on January 1, 2015 did not have a material impact on the Corporation's consolidated financial condition or results of operations.
Pending Accounting Pronouncements
Recognition and Measurement
In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities (ASU 2016-01). ASU 2016-01 amends current guidance by requiring companies to recognize changes in fair value for equity investments that have a readily determinable fair value through net income rather than through other comprehensive income. Under ASU 2016-01, equity investments that do not have a readily determinable fair value will either be accounted for the same as equity investments that have a readily determinable fair value, with changes in fair value recognized through net income, or carried at cost, adjusted for changes in observable prices based on orderly transactions for identical or similar investments issued by the same issuer and further adjusted for impairment, if applicable. ASU 2016-01 also requires a qualitative assessment of impairment indicators each reporting period. If this assessment indicates that impairment exists, companies must adjust the investment to fair value and recognize an impairment loss in net income, even if the impairment is determined to be temporary. ASU 2016-01 is effective for public companies for interim and annual periods beginning after December 15, 2017. The Corporation's adoption of ASU 2016-01 is not expected to have a material impact on the Corporation's consolidated financial condition or results of operations.

NOTE 2 — MERGERS AND ACQUISITIONS
Pending Merger with Talmer Bancorp, Inc.
On January 25, 2016, the Corporation entered into an Agreement and Plan of Merger with Talmer Bancorp, Inc. (Talmer). Under the terms of the merger agreement, each Talmer shareholder will receive $1.61 in cash and 0.4725 shares of the Corporation's common stock for each share of Talmer common stock, subject to adjustment in limited circumstances. Based on the 30-day volume weighted price per share of the Corporation's common stock as of January 25, 2016, the merger had a transaction value of approximately $1.1 billion. Following the completion of the merger, the Corporation intends to consolidate Talmer's wholly-owned subsidiary bank, Talmer Bank and Trust, with and into Chemical Bank. At December 31, 2015, Talmer had total assets of $6.6 billion, total loans of $4.8 billion and total deposits of $5.0 billion, including brokered deposits of $229 million. Talmer Bank and Trust is a full service community bank offering a full suite of commercial banking, retail banking, mortgage banking, wealth management and trust services to small and medium-sized businesses and individuals through 81 full service banking offices located primarily within southeast Michigan and northeast Ohio, as well as in west Michigan, northeast Michigan, Chicago, Illinois, northern Indiana, and Las Vegas, Nevada. Completion of the merger is subject to regulatory approval and the approval of the Corporation's and Talmer's shareholders, in addition to satisfaction of other customary closing conditions.
Acquisition of Lake Michigan Financial Corporation
On May 31, 2015, the Corporation acquired all of the outstanding stock of Lake Michigan Financial Corporation (Lake Michigan) for total consideration of $187.4 million, which included stock consideration of $132.9 million and cash consideration of $54.5 million. As a result of the acquisition, the Corporation issued approximately 4.3 million shares of its common stock, based on an exchange ratio of 1.326 shares of its common stock, and paid $16.64 in cash, for each share of Lake Michigan common stock outstanding. Lake Michigan, a bank holding company which owned The Bank of Holland and The Bank of Northern Michigan, provided traditional banking services and products with five banking offices in Holland, Grand Haven, Grand Rapids, Petoskey and Traverse City, Michigan. As of the May 31, 2015 acquisition date, Lake Michigan added total assets of $1.24 billion, including total loans of $986 million, and total deposits of $925 million to the Corporation. The Bank of Holland and The Bank of Northern Michigan were consolidated with and into Chemical Bank on November 13, 2015. The Corporation recorded $102 million of goodwill, which was primarily attributable to the synergies and economies of scale expected from combining the operations of the Corporation and Lake Michigan. In addition, the Corporation recorded $8.6 million of core deposit and other intangible assets in conjunction with the acquisition.
The results of the merged Lake Michigan operations are presented in the Corporation's consolidated financial statements from the date of acquisition. The disclosure of Lake Michigan's post-acquisition revenue and net income is not practical due to the combining of Lake Michigan's operations with and into Chemical Bank during the fourth quarter of 2015. Acquisition-related expenses associated with the Lake Michigan transaction totaled $5.5 million during 2015.
The summary computation of the purchase price, including adjustments to reflect Lake Michigan's assets acquired and liabilities assumed at fair value and the allocation of the purchase price to the net assets of Lake Michigan, is presented below. The acquisition accounting presented below may be further adjusted during a measurement period of up to one year beyond the acquisition date that provides the Corporation with the opportunity to finalize the acquisition accounting in the event that new information is identified that existed as of the acquisition date but was not known by the Corporation at that time. In accordance with ASU 2015-16, no amounts were recorded in the consolidated statements of income for the current reporting period for adjustments that would have been recorded in a previous reporting period had these adjustments been recognized as of the acquisition date.

During the three months ended December 31, 2015, additional valuation information was obtained related to the fair value of premises and equipment and other borrowings, which resulted in an adjustment to goodwill acquired in the Lake Michigan transaction. All amounts were previously reported in the Corporation's Quarterly Report on Form 10-Q for the three- and nine-month periods ended September 30, 2015, with the exception of goodwill, premises and equipment, other borrowings and deferred tax assets, net. The adjustments recorded during the fourth quarter of 2015, which resulted in a $0.7 million increase to the preliminary amount of goodwill recorded for the Lake Michigan transaction, included a $1.0 million write-down to premises and equipment related to updated information obtained regarding the fair market value of certain vacant land and non-branch locations, a $0.1 million increase in the fair value assigned to other borrowings based on updated assumptions utilized as part of the valuation, and a $0.4 million increase in the amount of recognizable deferred tax assets based on the tax impact of these adjustments.
Upon acquisition, the Lake Michigan loan portfolio had contractually required principal and interest payments receivable of $1.01 billion and $190.2 million, respectively, expected principal and interest cash flows of $986.1 million and $189.6 million, respectively, and a fair value of $985.5 million. The difference between the contractually required payments receivable and the expected cash flows represents the nonaccretable difference, which totaled $22.6 million at the acquisition date, with $22.0 million attributable to expected credit losses. The difference between the expected cash flows and fair value represents the accretable yield, which totaled $190.2 million at the date of acquisition. At December 31, 2015, the outstanding contractual principal balance and the carrying amount of the Lake Michigan acquired loan portfolio were $864 million and $842 million, respectively, and there was no related allowance for loan losses at that date.
Acquisition of Monarch Community Bancorp, Inc.
On April 1, 2015, the Corporation acquired all of the outstanding stock of Monarch Community Bancorp, Inc. (Monarch) in an all-stock transaction valued at $27.2 million. As a result of the acquisition, the Corporation issued 860,575 shares of its common stock based on an exchange ratio of 0.0982 shares of its common stock for each share of Monarch common stock outstanding. Monarch, a bank holding company, owned Monarch Community Bank, which operated five full service branch offices in Coldwater, Marshall, Hillsdale and Union City, Michigan. As of the April 1, 2015 acquisition date, Monarch added total assets of $183 million, including total loans of $122 million, and total deposits of $144 million to the Corporation's consolidated statement of financial position. Monarch Community Bank was consolidated with and into Chemical Bank on May 8, 2015. In connection with the acquisition of Monarch, the Corporation recorded $5.3 million of goodwill, which was primarily attributable to the synergies and economies of scale expected from combining the operations of the Corporation and Monarch. In addition, the Corporation recorded $1.9 million of core deposit intangible assets in conjunction with the acquisition.
The results of the merged Monarch operations are presented in the Corporation's consolidated financial statements from the date of acquisition. The disclosure of Monarch's post-acquisition revenue and net income is not practical due to the combining of Monarch's operations with and into Chemical Bank during the second quarter of 2015. Acquisition-related expenses associated with the Monarch transaction totaled $2.3 million during 2015.
The summary computation of the purchase price, including adjustments to reflect Monarch's assets acquired and liabilities assumed at fair value and the allocation of the purchase price to the net assets of Monarch is presented below. The acquisition accounting presented below may be further adjusted during a measurement period of up to one year beyond the acquisition date that provides the Corporation with the opportunity to finalize the acquisition accounting in the event that new information is identified that existed as of the acquisition date but was not known by the Corporation at that time. In accordance with ASU 2015-16, no amounts were recorded in the consolidated statements of income for the current reporting period for adjustments that would have been recorded in a previous reporting period had these adjustments been recognized as of the acquisition date.

During the three months ended December 31, 2015, additional valuation information was obtained related to the fair value of premises and equipment, which resulted in an immaterial adjustment to goodwill acquired in the Monarch transaction. All amounts were previously reported in the Corporation's Quarterly Report on Form 10-Q for the three- and nine-month periods ended September 30, 2015, with the exception of goodwill, premises and equipment and deferred tax assets, net.
Upon acquisition, the Monarch loan portfolio had contractually required principal and interest payments receivable of $128.9 million and $37.8 million, respectively, expected principal and interest cash flows of $122.6 million and $37.1 million, respectively, and a fair value of $121.8 million. The difference between the contractually required payments receivable and the expected cash flows represents the nonaccretable difference, which totaled $7.1 million at the acquisition date, with $6.3 million attributable to expected credit losses. The difference between the expected cash flows and fair value represents the accretable yield, which totaled $37.9 million at the date of acquisition. At December 31, 2015, the outstanding contractual principal balance and the carrying amount of the Monarch acquired loan portfolio were $115 million and $108 million, respectively, and there was no related allowance for loan losses at that date.
Acquisition of Northwestern Bancorp, Inc.
On October 31, 2014, the Corporation acquired all of the outstanding stock of Northwestern Bancorp, Inc. (Northwestern) for total cash consideration of $121 million. Northwestern, a bank holding company which owned Northwestern Bank, provided traditional banking services and products through 25 banking offices serving communities in the northwestern lower peninsula of Michigan. As of the October 31, 2014 acquisition date, Northwestern added total assets of $815 million, including total loans of $475 million, and total deposits of $794 million to the Corporation. Northwestern Bank was consolidated with and into Chemical Bank as of the acquisition date. In connection with the acquisition of Northwestern, the Corporation recorded $60.3 million of goodwill, which was primarily attributable to the synergies and economies of scale expected from combining the operations of the Corporation and Northwestern. In addition, the Corporation recorded $12.9 million of core deposit intangible assets in conjunction with the acquisition. During the fourth quarter of 2015 and prior to the end of the one year measurement period for finalizing the purchase price allocation, the Corporation obtained additional valuation information regarding the fair value of vacant land and closed branch locations, which resulted in a decrease to premises and equipment of $0.3 million, an increase to deferred tax assets of $0.1 million, and an increase to goodwill recognized in the transaction of $0.2 million. In accordance with ASU 2015-16, no amounts were recorded in the consolidated statements of income during 2015 for these adjustments that would have been recorded in a previous reporting period had these adjustments been recognized as of the acquisition date.
The results of the merged Northwestern operations are presented within the Corporation’s consolidated financial statements from the acquisition date. The disclosure of Northwestern's post-acquisition revenue and net income is not practical due to the combining of Northwestern Bank’s operations with and into Chemical Bank as of the October 31, 2014 acquisition date. Acquisition-related expenses associated with the Northwestern acquisition totaled $5.8 million during 2014.
Upon acquisition, the Northwestern loan portfolio had contractually required principal and interest payments receivable of $507 million and $112 million, respectively, expected principal and interest cash flows of $481 million and $104 million, respectively, and a fair value of $475 million. The difference between the contractually required payments receivable and the expected cash flows represents the nonaccretable difference, which totaled $34 million at the acquisition date, with $26 million attributable to expected credit losses. The difference between the expected cash flows and fair value represents the accretable yield, which totaled $110 million at the acquisition date. The outstanding contractual principal balance and the carrying amount of the Northwestern acquired loan portfolio were $361 million and $330 million, respectively, at December 31, 2015, compared to $485 million and $452 million, respectively, at December 31, 2014.

Represents additions in estimated contractual interest expected to be collected from acquired loans being renewed or extended, less reductions in contractual interest resulting from the early payoff of acquired loans.
As part of its ongoing assessment of the acquired loan portfolio, management determined during 2014 that the overall credit quality of the OAK acquired loan portfolio has improved, which had resulted in an improvement in expected cash flows of loan pools in the OAK acquired commercial loan portfolio. Accordingly, management reclassified $10.0 million during 2014 from the nonaccretable difference to the accretable yield for these acquired commercial loan pools, which will increase amounts recognized into interest income over the estimated remaining lives of these loan pools.

The majority of the Corporation's residential mortgage-backed securities and collateralized mortgage obligations are backed by a U.S. government agency (Government National Mortgage Association) or a government sponsored enterprise (Federal Home Loan Mortgage Corporation or Federal National Mortgage Association).
At December 31, 2014, the Corporation held a $10.5 million trust preferred investment security that had been issued by Lake Michigan. With the acquisition of Lake Michigan, this investment was settled as of the acquisition date at par.

An assessment is performed quarterly by the Corporation to determine whether unrealized losses in its investment securities portfolio are temporary or other-than-temporary by carefully considering all reasonably available information. The Corporation reviews factors such as financial statements, credit ratings, news releases and other pertinent information of the underlying issuer or company to make its determination. Management did not believe any individual unrealized loss on any investment security at December 31, 2015, represented an other-than-temporary impairment (OTTI). Management believed that the unrealized losses on investment securities at December 31, 2015 were temporary in nature and due primarily to changes in interest rates and reduced market liquidity and not as a result of credit-related issues.
At December 31, 2015, the Corporation did not have the intent to sell any of its impaired investment securities and believed that it was more-likely-than-not that the Corporation will not have to sell any such investment securities before a full recovery of amortized cost. Accordingly, at December 31, 2015, the Corporation believed the impairments in its investment securities portfolio were temporary in nature. However, there is no assurance that OTTI may not occur in the future.
Investment securities with an amortized cost of $516 million and $493 million at December 31, 2015 and 2014, respectively, were pledged to secure public fund deposits, short-term borrowings and for other purposes as required by law.
NOTE 4 — LOANS
Loan portfolio segments are defined as the level at which an entity develops and documents a systematic methodology to determine its allowance. The Corporation has two loan portfolio segments (commercial loans and consumer loans) that it uses in determining the allowance. Both quantitative and qualitative factors are used by management at the loan portfolio segment level in determining the adequacy of the allowance for the Corporation. Classes of loans are a disaggregation of an entity's loan portfolio segments. Classes of loans are defined as a group of loans which share similar initial measurement attributes, risk characteristics and methods for monitoring and assessing credit risk. The Corporation has seven classes of loans, which are set forth below.
Commercial — Loans and lines of credit to varying types of businesses, including municipalities, school districts and nonprofit organizations, for the purpose of supporting working capital, operational needs and term financing of equipment. Repayment of such loans is generally provided through operating cash flows of the business. Commercial loans are predominately secured by equipment, inventory, accounts receivable, personal guarantees of the owner and other sources of repayment, although the Corporation may also secure commercial loans with real estate.
Commercial real estate — Loans secured by real estate occupied by the borrower for ongoing operations, non-owner occupied real estate leased to one or more tenants and vacant land that has been acquired for investment or future land development.
Real estate construction — Secured loans for the construction of business properties. Real estate construction loans often convert to a commercial real estate loan at the completion of the construction period.
Land development — Secured development loans made to borrowers for the purpose of infrastructure improvements to vacant land to create finished marketable residential and commercial lots/land. Most land development loans are originated with the intention that the loans will be paid through the sale of developed lots/land by the developers within twelve months of the completion date. Land development loans at December 31, 2015 and 2014 were primarily comprised of loans to develop residential properties.
Residential mortgage — Loans secured by one- to four-family residential properties, generally with fixed interest rates for periods of fifteen years or less. The loan-to-value ratio at the time of origination is generally 80% or less. Residential mortgage loans with a loan-to-value ratio of more than 80% generally require private mortgage insurance.
Consumer installment — Loans to consumers primarily for the purpose of acquiring automobiles, recreational vehicles and personal watercraft and comprised primarily of indirect loans purchased from dealers. These loans consist of relatively small amounts that are spread across many individual borrowers.
Home equity — Loans and lines of credit whereby consumers utilize equity in their personal residence, through a first or second lien mortgage, as collateral to secure the loan.
Commercial, commercial real estate, real estate construction and land development loans are referred to as the Corporation's commercial loan portfolio, while residential mortgage, consumer installment and home equity loans are referred to as the Corporation's consumer loan portfolio.

Chemical Bank has extended loans to its directors, executive officers and their affiliates. These loans were made in the ordinary course of business upon normal terms, including collateralization and interest rates prevailing at the time, and did not involve more than the normal risk of repayment by the borrower. The aggregate loans outstanding to the directors, executive officers and their affiliates totaled $21.7 million at December 31, 2015 and $31.2 million at December 31, 2014. During 2015 and 2014, there were $33.3 million and $39.3 million, respectively, of new loans and other additions, while repayments and other reductions totaled $42.8 million and $34.9 million, respectively.
Loans held-for-sale, comprised of fixed-rate residential mortgage loans, were $10.3 million at December 31, 2015 and $9.1 million at December 31, 2014. The Corporation sold residential mortgage loans totaling $223 million in 2015 and $149 million in 2014.
Credit Quality Monitoring
The Corporation maintains loan policies and credit underwriting standards as part of the process of managing credit risk. These standards include making loans generally only within the Corporation's market areas. The Corporation's lending markets generally consist of communities across the lower peninsula of Michigan, except for the southeastern portion of Michigan. The Corporation has no foreign loans.
The Corporation, through Chemical Bank, has a commercial loan portfolio approval process involving underwriting and individual and group loan approval authorities to consider credit quality and loss exposure at loan origination. The loans in the Corporation's commercial loan portfolio are risk rated at origination based on the grading system set forth below. The approval authority of relationship managers is established based on experience levels, with credit decisions greater than $1.0 million requiring group loan authority approval, except for six executive and senior officers who have varying loan limits exceeding $1.5 million and up to $3.5 million. With respect to the group loan authorities, Chemical Bank has a loan committee, consisting of certain executive and senior officers, that meets weekly to consider loans ranging in amounts from $1.0 million to $10.0 million, depending on risk rating and credit action required. A directors' loan committee of Chemical Bank, consisting of eight independent members of the board of directors of Chemical Bank, the chief executive officer of Chemical Bank and the senior credit officer of Chemical Bank, meets bi-weekly to consider loans in amounts over $10.0 million, and certain loans under $10.0 million depending on a loan's risk rating and credit action required. Loans over $15.0 million require the approval of the board of directors of Chemical Bank.
The majority of the Corporation's consumer loan portfolio is comprised of secured loans that are relatively small. The Corporation's consumer loan portfolio has a centralized approval process which utilizes standardized underwriting criteria. The ongoing measurement of credit quality of the consumer loan portfolio is largely done on an exception basis. If payments are made on schedule, as agreed, then no further monitoring is performed. However, if delinquency occurs, the delinquent loans are turned over to the Corporation's collection department for resolution, resulting in repossession or foreclosure if payments are not brought current. Credit quality for the entire consumer loan portfolio is measured by the periodic delinquency rate, nonaccrual amounts and actual losses incurred.

92

Loans in the commercial loan portfolio tend to be larger and more complex than those in the consumer loan portfolio, and therefore, are subject to more intensive monitoring. All loans in the commercial loan portfolio have an assigned relationship manager, and most borrowers provide periodic financial and operating information that allows the relationship managers to stay abreast of credit quality during the life of the loans. The risk ratings of loans in the commercial loan portfolio are reassessed at least annually, with loans below an acceptable risk rating reassessed more frequently and reviewed by various loan committees within the Corporation at least quarterly.
The Corporation maintains a centralized independent loan review function that monitors the approval process and ongoing asset quality of the loan portfolio, including the accuracy of loan grades. The Corporation also maintains an independent appraisal review function that participates in the review of all appraisals obtained by the Corporation for loans in the commercial loan portfolio.
Credit Quality Indicators
Commercial Loan Portfolio
The Corporation uses a nine grade risk rating system to monitor the ongoing credit quality of its commercial loan portfolio. These loan grades rank the credit quality of a borrower by measuring liquidity, debt capacity, coverage and payment behavior as shown in the borrower's financial statements. The loan grades also measure the quality of the borrower's management and the repayment support offered by any guarantors. A summary of the Corporation's loan grades (or, characteristics of the loans within each grade) follows:
Risk Grades 1-5 (Acceptable Credit Quality) — All loans in risk grades 1 through 5 are considered to be acceptable credit risks by the Corporation and are grouped for purposes of allowance for loan loss considerations and financial reporting. The five grades essentially represent a ranking of loans that are all viewed to be of acceptable credit quality, taking into consideration the various factors mentioned above, but with varying degrees of financial strength, debt coverage, management and factors that could impact credit quality. Business credits within risk grades 1 through 5 range from Risk Grade 1: Prime Quality (factors include: excellent business credit; excellent debt capacity and coverage; outstanding management; strong guarantors; superior liquidity and net worth; favorable loan-to-value ratios; debt secured by cash or equivalents, or backed by the full faith and credit of the U.S. Government) to Risk Grade 5: Acceptable Quality With Care (factors include: acceptable business credit, but with added risk due to specific industry or internal situations).
Risk Grade 6 (Watch) — A business credit that is not acceptable within the Corporation's loan origination criteria; cash flow may not be adequate or is continually inconsistent to service current debt; financial condition has deteriorated as company trends/management have become inconsistent; the company is slow in furnishing quality financial information; working capital needs of the company are reliant on short-term borrowings; personal guarantees are weak and/or with little or no liquidity; the net worth of the company has deteriorated after recent or continued losses; the loan requires constant monitoring and attention from the Corporation; payment delinquencies becoming more serious; if left uncorrected, these potential weaknesses may, at some future date, result in deterioration of repayment prospects.
Risk Grade 7 (Substandard — Accrual) — A business credit that is inadequately protected by the current financial net worth and paying capacity of the obligor or of the collateral pledged, if any; management has deteriorated or has become non-existent; quality financial information is not available; a high level of maintenance is required by the Corporation; cash flow can no longer support debt requirements; loan payments are continually and/or severely delinquent; negative net worth; personal guaranty has become insignificant; a credit that has a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. The Corporation still expects a full recovery of all contractual principal and interest payments; however, a possibility exists that the Corporation will sustain some loss if deficiencies are not corrected.
Risk Grade 8 (Substandard — Nonaccrual) — A business credit accounted for on a nonaccrual basis that has all the weaknesses inherent in a loan classified as risk grade 7 with the added characteristic that the weaknesses are so pronounced that, on the basis of current financial information, conditions and values, collection in full is highly questionable; a partial loss is possible and interest is no longer being accrued. This loan meets the definition of an impaired loan. The risk of loss requires analysis to determine whether a valuation allowance needs to be established.
Risk Grade 9 (Substandard — Doubtful) — A business credit that has all the weaknesses inherent in a loan classified as risk grade 8 and interest is no longer being accrued, but additional deficiencies make it highly probable that liquidation will not satisfy the majority of the obligation; the primary source of repayment is nonexistent and there is doubt as to the value of the secondary source of repayment; the possibility of loss is likely, but current pending factors could strengthen the credit. This loan meets the definition of an impaired loan. A loan charge-off is recorded when management deems an amount uncollectible; however, the Corporation will establish a valuation allowance for probable losses, if required.

93

The Corporation considers all loans graded 1 through 5 as acceptable credit risks and structures and manages such relationships accordingly. Periodic financial and operating data combined with regular loan officer interactions are deemed adequate to monitor borrower performance. Loans graded 6 and 7 are considered higher-risk credits than loans graded 1 through 5 and the frequency of loan officer contact and receipt of financial data is increased to stay abreast of borrower performance. Loans graded 8 and 9 are considered problematic and require special care. Further, loans graded 6 through 9 are managed and monitored regularly through a number of processes, procedures and committees, including oversight by a loan administration committee comprised of executive and senior management of the Corporation, and include highly structured reporting of financial and operating data, intensive loan officer intervention and strategies to exit, as well as potential management by the Corporation's special assets group.

Consumer Loan Portfolio
The Corporation evaluates the credit quality of loans in the consumer loan portfolio based on the performing or nonperforming status of the loan. Loans in the consumer loan portfolio that are performing in accordance with original contractual terms and are less than 90 days past due and accruing interest are considered to be in a performing status, while those that are in nonaccrual status, contractually past due 90 days or more as to interest or principal payments or classified as a nonperforming TDR are considered to be in a nonperforming status. Nonaccrual TDRs in the consumer loan portfolio are included with nonaccrual loans, while other TDRs in the consumer loan portfolio are considered to be in a nonperforming status until they meet the Corporation's definition of a performing TDR, at which time they are considered to be in a performing status.
The following schedule presents the recorded investment of loans in the consumer loan portfolio based on loans in a performing status and loans in a nonperforming status at December 31, 2015 and 2014:

The average annual recorded investment of impaired loans during 2013 was $121.0 million and was comprised of the following classes of loans: commercial - $29.6 million; commercial real estate - $50.8 million; real estate construction - $0.4 million; land development - $9.8 million; residential mortgage - $26.8 million; consumer installment - $0.7 million; and home equity - $2.9 million. Interest income recognized during 2013 while these loans were in impaired status was $3.8 million, including $1.0 million on commercial loans, $1.3 million on commercial real estate loans, $0.3 million on land development loans and $1.1 million on residential mortgage loans.
The difference between an impaired loan's recorded investment and the unpaid principal balance for originated loans represents a partial charge-off resulting from a confirmed loss due to the value of the collateral securing the loan being below the loan balance and management's assessment that full collection of the loan balance is not likely, and for acquired loans that meet the definition of an impaired loan represents fair value adjustments recognized at the acquisition date attributable to expected credit losses and the discounting of expected cash flows at market interest rates. The difference between the recorded investment and the unpaid principal balance of $25.3 million and $30.6 million at December 31, 2015 and December 31, 2014, respectively, includes confirmed losses (partial charge-offs) of $17.1 million and $15.4 million, respectively, and fair value discount adjustments of $8.2 million and $15.2 million, respectively.
Impaired loans included $12.8 million and $19.9 million at December 31, 2015 and December 31, 2014, respectively, of acquired loans that were not performing in accordance with original contractual terms. Acquired loans that are not performing in accordance with contractual terms are not reported as nonperforming loans because these loans are recorded in pools at their net realizable value based on the principal and interest the Corporation expects to collect on these loans. Impaired loans also included $47.8 million and $45.7 million at December 31, 2015 and December 31, 2014, respectively, of performing TDRs.

The pre-modification and post-modification recorded investment represents amounts as of the date of loan modification. The difference between the pre-modification and post-modification recorded investment of residential mortgage TDRs represents impairment recognized by the Corporation through the provision for loan losses computed based on a loan's post-modification present value of expected future cash flows discounted at the loan's original effective interest rate.
The following schedule includes TDRs for which there was a payment default during the years ended December 31, 2015, 2014 and 2013, whereby the borrower was past due with respect to principal and/or interest for 90 days or more, and the loan became a TDR during the twelve-month period prior to the default:

The allowance attributable to acquired loans of $0.5 million at December 31, 2014 was primarily attributable to two consumer loan pools in the acquired loan portfolio that had a decline in expected cash flows. There were no material changes in expected cash flows for the acquired loan pools at December 31, 2015.

NOTE 6 — GOODWILL
Goodwill was $287.4 million at December 31, 2015 and $180.1 million at December 31, 2014. During 2015, the Corporation acquired Lake Michigan and Monarch, which resulted in the recognition of goodwill for each transaction of $101.6 million and $5.3 million, respectively. During 2014, the Corporation acquired Northwestern, which resulted in the recognition of $60.0 million of goodwill. The Corporation also recorded additional goodwill in 2015 of $0.3 million related to the acquisition of Northwestern resulting from adjustments to the original acquisition date valuation of acquired assets and liabilities. Goodwill recognized in the Lake Michigan, Monarch and Northwestern transactions was primarily attributable to the synergies and economies of scale expected from combining their operations with the Corporation. None of the goodwill recorded in conjunction with the Lake Michigan, Monarch and Northwestern acquisitions is deductible for tax purposes.
Goodwill is subject to impairment testing annually and on an interim basis if events or changes in circumstances indicate assets might be impaired. The Corporation's most recent annual goodwill impairment assessment, which was performed as of October 31, 2015, did not indicate that an impairment of goodwill existed. The Corporation also determined that no triggering events occurred that indicated impairment from the most recent assessment date through December 31, 2015 and that the Corporation's goodwill was not impaired at December 31, 2015.

In conjunction with the acquisitions of Lake Michigan on May 31, 2015 and Monarch on April 1, 2015, the Corporation recorded $8.0 million and $1.9 million, respectively, in core deposit intangible assets. In conjunction with the acquisition of Northwestern on October 31, 2014, the Corporation recorded $12.9 million in core deposit intangible assets.
The estimated future amortization expense on core deposit intangible assets for the years ending after December 31, 2015 is as follows: 2016 - $4.4 million; 2017 - $3.8 million; 2018 - $3.6 million; 2019 - $3.4 million; 2020 - $2.9 million; 2021 and thereafter - $8.6 million.
Non-compete Intangible Assets
In conjunction with the acquisition of Lake Michigan on May 31, 2015, the Corporation recorded $0.6 million in non-compete intangible assets with an amortization period of one year. There were no additions of non-compete intangible assets in 2014.

Mortgage Servicing Rights (MSRs)

Loans serviced for others that have servicing rights capitalized
 
$

$
2,093,140

The fair value of MSRs was estimated by calculating the present value of estimated future net servicing cash flows, taking into consideration expected prepayment rates, discount rates, servicing costs and other economic factors that are based on current market conditions. The prepayment rates and the discount rate are the most significant factors affecting valuation of the MSRs. Increases in mortgage loan prepayments reduce estimated future net servicing cash flows because the life of the underlying loan is reduced. Expected loan prepayment rates are validated by a third-party model. At December 31, 2015, the weighted average coupon rate, discount rate and constant prepayment rate (CPR) of the Corporation's $888 million originated servicing portfolio was 4.20%, 8.5% and 11.7%, respectively, while the weighted average coupon rate, discount rate and CPR of the Corporation's $1.20 billion acquired servicing portfolio was 4.07%, 10.1% and 10.41%, respectively. At December 31, 2014, the weighted average coupon rate, discount rate and CPR of the Corporation's $881 million originated servicing portfolio was 4.28%, 8.5% and 13.6%, respectively, while the weighted average coupon rate, discount rate and CPR of the Corporation's $1.21 billion acquired servicing portfolio was 4.08%, 10.1% and 11.7%, respectively.

The Corporation acquired MSRs of $1.3 million in the acquisition of Monarch on April 1, 2015 and $9.2 million in the acquisition of Northwestern on October 31, 2014. MSRs are stratified into servicing assets originated by the Corporation and those acquired in acquisitions of other institutions and further stratified into relatively homogeneous pools based on products with similar characteristics. The MSR impairment valuation allowance recorded at December 31, 2014 related to impairment within certain pools attributable to the Corporation's servicing portfolio that was acquired in the Northwestern transaction.

During the third quarter of 2015, the Corporation borrowed $100 million of long-term FHLB advances, which consist of three- and five-year term fixed-rate advances with a weighted-average interest rate of 1.48%. In conjunction with the Lake Michigan and Monarch acquisitions, the Corporation acquired long-term FHLB advances totaling $81.5 million. These advances have a weighted average interest rate of 1.33% at December 31, 2015. The Corporation's FHLB advances, including both short-term and long-term, require monthly interest payments. The scheduled reductions of long-term FHLB advances as of December 31, 2015 were as follows: 2016 - $7.1 million; 2017 - $47.1 million; 2018 - $67.1 million; 2019; - $0.1 million; and 2020 - $60.0 million.
FHLB advances are collateralized by a blanket lien on qualified one- to four-family residential mortgage loans. At December 31, 2015, the carrying value of these qualified loans was $1.34 billion. The Corporation's additional borrowing availability through the FHLB, subject to the FHLB's credit requirements and policies and based on the amount of FHLB stock owned by the Corporation, was $250 million at December 31, 2015.
Prepayments of fixed-rate advances are subject to prepayment fees under the provisions and conditions of the credit policy of the FHLB. On January 22, 2013, the Corporation paid off early all of its FHLB advances outstanding at that time of $34.3 million, resulting in a prepayment fee of $0.8 million. The Corporation did not incur any prepayment fees in 2015 or 2014.
The Corporation entered into a $25 million secured non-revolving line-of-credit in May 2015 with an unaffiliated third-party financial institution. The Corporation drew on the entire amount of the line-of-credit in order to partially fund the cash portion of the purchase price consideration for the Lake Michigan transaction. The line-of-credit bears a variable rate of interest which is based on the one-, two- or three-month LIBOR, as periodically selected by the Corporation, plus a fixed stated rate (effective interest rate of 2.27% at December 31, 2015), and matures in May 2016. The line-of-credit agreement contains certain restrictive covenants. The Corporation was in compliance with all of the covenants at December 31, 2015. The line-of-credit is secured by all of the issued and outstanding stock of Chemical Bank.
In conjunction with the Lake Michigan acquisition, the Company acquired securities sold under agreements to repurchase with an unaffiliated financial institution of $23.7 million as of the acquisition date. These agreements are secured by available for-sale-securities. As of December 31, 2015, these agreements had scheduled maturities of $8.3 million in 2016 and $9.1 million in 2017.
In conjunction with the acquisition of Lake Michigan on May 31, 2015, the Corporation acquired Lake Michigan Financial Capital Trust I (LMFCTI), Lake Michigan Financial Capital Trust II (LMFCTII), and Lake Michigan Financial Capital Trust III (LMFCTIII). LMFCTIII, which held the $10.0 million trust preferred security due to the Corporation, was repaid and settled as of the Lake Michigan acquisition date, and the entity was subsequently dissolved. All of the common securities of the remaining two special purpose trusts are owned by the Corporation. The trusts exist solely to issue capital securities in the form of cumulative preferred securities (trust preferred securities) with a par value of $1,000 per security. The proceeds from the sale of the trust preferred securities were used by each trust to purchase an equivalent amount of subordinated debentures from Lake Michigan. Lake Michigan guaranteed the payment of distributions on the trust preferred securities issued by LMFCTI and LMFCTII. At the acquisition date, the Corporation assumed responsibility of the guarantees.
LMFCTI issued $10.3 million in preferred securities in October 2002. This trust preferred subordinated debt, with a stated maturity date of October 2032, pays interest based on a floating rate tied to the three-month LIBOR plus 3.45% (effective interest rate based on par of 3.99% as of December 31, 2015). LMFCTII issued $8.2 million in preferred securities in May 2004. This trust preferred subordinated debt, with a stated maturity date of May 2034, pays interest based on a floating rate tied to the three-month LIBOR plus 2.7% (effective interest rate based on par of 3.24% as of December 31, 2015). Including the impact of recording these subordinated debentures at fair value at the acquisition date, the weighted-average cost of these obligations was 3.99% as of December 31, 2015. The Corporation may, at any time, redeem the LMFCTI or LMFCTII subordinated debentures at par. The Corporation has notified the respective trust's trustee of its intent to pay off these debt obligations during the first quarter of 2016.

NOTE 11 — EQUITY
Common Stock Repurchase Programs
From time to time, the board of directors of the Corporation approves common stock repurchase programs allowing management to repurchase shares of the Corporation's common stock in the open market. The repurchased shares are available for later reissuance in connection with potential future stock dividends, employee benefit plans and other general corporate purposes. Under these programs, the timing and actual number of shares subject to repurchase are at the discretion of management and are contingent on a number of factors, including the projected parent company cash flow requirements and the Corporation's market price per share.
In January 2008, the board of directors of the Corporation authorized the repurchase of up to 500,000 shares of the Corporation's common stock under a stock repurchase program. In November 2011, the board of directors of the Corporation reaffirmed the stock buy-back authorization with the qualification that the shares may only be repurchased if the share price is below the tangible book value per share of the Corporation's common stock at the time of the repurchase. Since the January 2008 authorization, no shares have been repurchased. At December 31, 2015, there were 500,000 remaining shares available for repurchase under the Corporation's stock repurchase programs.
Underwritten Public Offerings of Common Stock
On June 24, 2014, the Corporation issued and sold 2,500,000 shares of common stock at a public offering price of $28.00 per share. An additional 375,000 shares were issued and sold on June 30, 2014 upon the exercise in full of the underwriters' over-allotment option. The net proceeds from the issuance and sale of the common stock of this $80.5 million offering, after deducting the underwriting discount and issuance-related expenses, totaled $76.2 million.
On September 18, 2013, the Corporation issued and sold 2,213,750 shares of common stock, including 288,750 shares of common stock that were issued and sold upon the exercise in full of the underwriters' over-allotment option, at a public offering price of $26.00 per share. The net proceeds from the issuance and sale of the common stock of this $57.6 million offering, after deducting the underwriting discount and issuance-related expenses, totaled $53.9 million.
Shelf Registration
On June 12, 2014, the Corporation filed an automatic shelf registration statement on Form S-3 with the Securities and Exchange Commission (SEC) for an indeterminate amount of securities, which became immediately effective. The shelf registration statement provides the Corporation with the ability to raise capital, subject to SEC rules and limitations, if the board of directors of the Corporation decides to do so.
Preferred Stock
On April 20, 2015, the shareholders of the Corporation approved an amendment to the restated articles of incorporation which eliminated and replaced the previous class of 200,000 shares of preferred stock, that had been approved by shareholders on April 20, 2009, with a new class of 2,000,000 shares of preferred stock. As of December 31, 2015, no shares of preferred stock were issued and outstanding.
Common Stock
On April 20, 2015, the shareholders of the Corporation approved an amendment to the restated articles of incorporation to increase the number of authorized shares of common stock from 45,000,000 to 60,000,000.

NOTE 13 — FAIR VALUE MEASUREMENTS
Fair value, as defined by GAAP, is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability. The price in the principal (or most advantageous) market used to measure the fair value of the asset or liability is not adjusted for transaction costs. An orderly transaction is a transaction that assumes exposure to the market for a period prior to the measurement date to allow for market activities that are usual and customary for transactions involving such assets and liabilities; it is not a forced transaction. Market participants are buyers and sellers in the principal market that are (i) independent, (ii) knowledgeable, (iii) able to transact and (iv) willing to transact.
The Corporation utilizes fair value measurements to record fair value adjustments to certain assets and to determine fair value disclosures. Investment securities — available-for-sale and loans held-for-sale are recorded at fair value on a recurring basis. Additionally, the Corporation may be required to record other assets, such as impaired loans, goodwill, other intangible assets, other real estate and repossessed assets, at fair value on a nonrecurring basis. These nonrecurring fair value adjustments typically involve the application of lower of cost or market accounting or write-downs of individual assets.
The Corporation determines the fair value of its financial instruments based on a three-level hierarchy established by GAAP. The classification and disclosure of assets and liabilities within the hierarchy is based on whether the inputs to the valuation methodology used for measurement are observable or unobservable. Observable inputs reflect market-derived or market-based information obtained from independent sources, while unobservable inputs reflect management's estimates about market data. The three levels of inputs that may be used to measure fair value within the GAAP hierarchy are as follows:
Level 1
Valuation is based upon quoted prices for identical instruments traded in active markets. Level 1 valuations for the Corporation would include U.S. Treasury securities that are traded by dealers or brokers in active over-the-counter markets. Valuations are obtained from a third-party pricing service for Level 1 investment securities.
Level 2
Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market. Level 2 valuations for the Corporation include government sponsored agency securities, including securities issued by the Federal Home Loan Bank, Federal Home Loan Mortgage Corporation, Federal National Mortgage Association, Federal Farm Credit Bank, Student Loan Marketing Corporation and the Small Business Administration, securities issued by certain state and political subdivisions, residential mortgage-backed securities, collateralized mortgage obligations, corporate bonds, preferred stock and available-for-sale trust preferred securities. Valuations are obtained from a third-party pricing service for these investment securities.
Level 3
Valuation is generated from model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include use of option pricing models, discounted cash flow models, yield curves and similar techniques. The determination of fair value requires management judgment or estimation and generally is corroborated by external data, which includes third-party pricing services. Level 3 valuations for the Corporation include securities issued by certain state and political subdivisions, held-to-maturity trust preferred investment securities, impaired loans, goodwill, core deposit intangible assets, non-compete intangible assets, MSRs and other real estate and repossessed assets.
A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. These valuation methodologies were applied to all of the Corporation's financial assets and financial liabilities carried at fair value and all financial instruments disclosed at fair value. In general, fair value is based upon quoted market prices, where available. If quoted market prices are not available, fair value is based upon third-party pricing services when available. Fair value may also be based on internally developed models that primarily use, as inputs, observable market-based parameters. Valuation adjustments may be required to record financial instruments at fair value. Any such valuation adjustments are applied consistently over time. The Corporation's valuation methodologies may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values.
While management believes the Corporation's valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. Furthermore, the fair value amounts may change significantly after the date of the statement of financial position from the amounts reported in the consolidated financial statements and related notes.

108

Assets and Liabilities Recorded at Fair Value on a Recurring Basis
Investment securities — available-for-sale are recorded at fair value on a recurring basis. Fair value measurement is based upon quoted prices, if available. If quoted prices are not available, fair values are generally measured using independent pricing models or other model-based valuation techniques that include market inputs, such as benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, reference data and industry and economic events.
The Corporation elected the fair value option for all residential mortgage loans held-for-sale originated on or after July 1, 2012. Accordingly, loans held-for-sale are recorded at fair value on a recurring basis. The fair values of loans held-for-sale are based on the market price for similar loans sold in the secondary market, and therefore, are classified as Level 2 valuations.

There were no liabilities recorded at fair value on a recurring basis at December 31, 2015 or 2014.

109

Assets and Liabilities Recorded at Fair Value on a Nonrecurring Basis
The Corporation does not record loans held for investment at fair value on a recurring basis. However, from time to time, a loan is considered impaired and an allocation of the allowance (valuation allowance) may be established or a portion of the loan is charged off. Loans for which it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement are considered impaired. The fair value of impaired loans is estimated using one of several methods, including the loan's observable market price, the fair value of the collateral or the present value of the expected future cash flows discounted at the loan's effective interest rate. Those impaired loans not requiring a valuation allowance represent loans for which the fair value of the expected repayments or collateral exceed the remaining carrying amount of such loans. Impaired loans where a valuation allowance is established or a portion of the loan is charged off based on the fair value of collateral are subject to nonrecurring fair value measurement and require classification in the fair value hierarchy. The Corporation records impaired loans as Level 3 valuations as there is generally no observable market price or independent appraised value, or management determines the fair value of the collateral is further impaired below the appraised value. When management determines the fair value of the collateral is further impaired below the appraised value, discount factors ranging between 70% and 80% of the appraised value are used depending on the nature of the collateral and the age of the most recent appraisal.
Goodwill is subject to impairment testing on an annual basis. The assessment of goodwill for impairment requires a significant degree of judgment. In the event the assessment indicates that it is more-likely-than-not that the fair value is less than the carrying value, the asset is considered impaired and recorded at fair value. Goodwill that is impaired and subject to nonrecurring fair value measurements is a Level 3 valuation. At December 31, 2015 and 2014, no goodwill was impaired and, therefore, goodwill was not recorded at fair value on a nonrecurring basis.
Other intangible assets consist of core deposit intangible assets, non-compete intangible assets and MSRs. These items are recorded at fair value when initially recorded. Subsequently, core deposit intangible assets and non-compete intangible assets are amortized primarily on an accelerated basis over periods ranging from ten to fifteen years and are subject to impairment testing whenever events or changes in circumstances indicate that the carrying amount exceeds the fair value of the asset. If core deposit intangible asset or non-compete intangible asset impairment is identified, the Corporation classifies impaired core deposit intangible assets subject to nonrecurring fair value measurements as Level 3 valuations. At December 31, 2015 and 2014, there was no impairment identified for core deposit intangible assets or non-compete intangible assets. The fair value of MSRs is estimated using a model that calculates the net present value of estimated future cash flows using various assumptions, including prepayment speeds, the discount rate and servicing costs. If the valuation model reflects a value less than the carrying value, MSRs are adjusted to fair value, as determined by the model, through a valuation allowance. The Corporation classifies MSRs subject to nonrecurring fair value measurements as Level 3 valuations. At December 31, 2014,the Corporation recognized a $0.2 million valuation allowance related to impairment within certain pools attributable to the Corporation's servicing portfolio that was acquired in the Northwestern transaction. As a result, the MSRs related to this servicing portfolio were considered to be recorded at fair value on a nonrecurring basis. At December 31, 2015, there was no impairment identified for MSRs and, therefore, no other intangible assets were recorded at fair value on a nonrecurring basis.
The carrying amounts for other real estate (ORE) and repossessed assets (RA) are reported in the consolidated statements of financial position under "Interest receivable and other assets." ORE and RA include real estate and other types of assets repossessed by the Corporation. ORE and RA are recorded at the lower of cost or fair value upon the transfer of a loan to ORE or RA and, subsequently, ORE and RA continue to be measured and carried at the lower of cost or fair value. Fair value is based upon independent market prices, appraised values of the property or management's estimation of the value of the property. The Corporation records ORE and RA as Level 3 valuations as management generally determines that the fair value of the property is impaired below the appraised value. When management determines the fair value of the property is further impaired below appraised value, discount factors ranging between 70% and 75% of the appraised value are used depending on the nature of the property and the age of the most recent appraisal.

There were no liabilities recorded at fair value on a nonrecurring basis at December 31, 2015 and 2014.
Disclosures About Fair Value of Financial Instruments
GAAP requires disclosures about the estimated fair value of the Corporation's financial instruments, including those financial assets and liabilities that are not measured and reported at fair value on a recurring or nonrecurring basis. However, the method of estimating fair value for certain financial instruments, such as loans, that are not required to be measured on a recurring or nonrecurring basis, as prescribed by ASC 820, Fair Value Measurements and Disclosures, does not incorporate the exit-price concept of fair value. The Corporation utilized the fair value hierarchy in computing the fair values of its financial instruments. In cases where quoted market prices were not available, the Corporation employed present value methods using unobservable inputs requiring management's judgment to estimate the fair values of its financial instruments, which are considered Level 3 valuations. These Level 3 valuations are affected by the assumptions made and, accordingly, do not necessarily indicate amounts that could be realized in a current market exchange. It is also the Corporation's general practice and intent to hold the majority of its financial instruments until maturity and, therefore, the Corporation does not expect to realize the estimated amounts disclosed.
The methodologies for estimating the fair value of financial assets and financial liabilities on a recurring or nonrecurring basis are discussed above. At December 31, 2015 and 2014, the estimated fair values of cash and cash equivalents, interest receivable and interest payable approximated their carrying values at those dates. The methodologies for other financial assets and financial liabilities follow.
Fair value measurement for investment securities — held-to-maturity is based upon quoted prices, if available. If quoted prices are not available, fair values are measured using independent pricing models or other model-based valuation techniques that include market inputs such as benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, reference data and industry and economic events. Fair value measurements using Level 2 valuations of investment securities — held-to-maturity include the majority of the Corporation's investment securities issued by state and political subdivisions. Level 3 valuations include certain securities issued by state and political subdivisions and trust preferred investment securities.
Fair value measurements of nonmarketable equity securities, which consisted of Federal Home Loan Bank (FHLB) and Federal Reserve Bank (FRB) stock, are based on their redeemable value, which is cost. The market for these securities is restricted to the issuer of the stock and subject to impairment evaluation. It is not practicable to determine the fair value of these securities within the fair value hierarchy due to the restrictions placed on their transferability.
Loans held-for-sale are carried at fair value, as the Corporation elected the fair value option on these loans. The fair value of loans held-for-sale are based on the market price for similar loans sold in the secondary market and, therefore, are classified as Level 2 valuations.

111

The fair value of variable interest rate loans that reprice regularly with changes in market interest rates are based on carrying values. The fair values for fixed interest rate loans are estimated using discounted cash flow analyses, using the Corporation's interest rates currently being offered for loans with similar terms to borrowers of similar credit quality. The resulting fair value amounts are adjusted to estimate the impact of changes in the credit quality of borrowers after the loans were originated. The fair value measurements for loans are Level 3 valuations.
The fair values of deposit accounts without defined maturities, such as interest- and noninterest-bearing checking, savings and money market accounts, are equal to the amounts payable on demand. The fair values for variable-interest rate time deposits with defined maturities approximate their carrying amounts. Fair value measurements for fixed-interest rate time deposits with defined maturities are based on the discounted value of contractual cash flows, using the Corporation's interest rates currently being offered for deposits of similar maturities and are Level 3 valuations. However, if the estimated fair value is less than the carrying value, the carrying value is reported as the fair value.
Short-term borrowings consist of securities sold under agreements to repurchase with customers, short-term FHLB advances and federal funds purchased. Fair value measurements for short-term borrowings are based on the present value of future estimated cash flows using current interest rates offered to the Corporation for debt with similar terms and are Level 2 valuations. Other borrowings consist of long-term FHLB advances, securities sold under agreements to repurchase with an unaffiliated financial institution, a non-revolving line-of-credit and subordinated debentures. Fair value measurements for other borrowings are based on the present value of future estimated cash flows using current interest rates offered to the Corporation for debt with similar terms. Long-term FHLB advances and the non-revolving line-of-credit included in other borrowings are Level 2 valuations, while securities sold under agreements to repurchase with an unaffiliated financial institution and subordinated debentures are Level 3 valuations.
The Corporation's unused commitments to extend credit, standby letters of credit and loan commitments have no carrying amount and have been estimated to have no realizable fair value. Historically, a majority of the unused commitments to extend credit have not been drawn upon and, generally, the Corporation does not receive fees in connection with these commitments other than standby letter of credit fees, which are not significant.
Fair value measurements have not been made for items that are not defined by GAAP as financial instruments, including such items as the value of the Corporation's Wealth Management department and the value of the Corporation's core deposit base. The Corporation believes it is impractical to estimate a representative fair value for these types of assets, even though management believes they add significant value to the Corporation.

NOTE 16 — RETIREMENT PLANS
Defined Benefit Pension Plan
The Corporation has a noncontributory defined benefit pension plan (Pension Plan) covering certain salaried employees. Benefits under the Pension Plan were frozen for approximately two-thirds of the Corporation's salaried employees effective June 30, 2006. Pension benefits continued unchanged for the remaining salaried employees. Normal retirement benefits under the Pension Plan are based on years of vested service, up to a maximum of thirty years, and the employee's average annual pay for the five highest consecutive years during the ten years preceding retirement, except for employees whose benefits were frozen. Benefits, for employees with less than 15 years of service or whose age plus years of service were less than 65 at June 30, 2006, will be based on years of vested service at June 30, 2006 and generally the average of the employee's salary for the five years ended June 30, 2006. At December 31, 2015, the Corporation had 161 employees who were continuing to earn benefits under the Pension Plan. Pension Plan contributions are intended to provide not only for benefits attributed to service-to-date, but also for those benefits expected to be earned in the future for employees whose benefits were not frozen at June 30, 2006. Employees hired after June 30, 2006 and employees affected by the partial freeze of the Pension Plan began receiving 4% of their eligible pay as a contribution to their 401(k) Savings Plan accounts on July 1, 2006. Pension Plan expense was $1.6 million in 2015, zero in 2014 and $1.7 million in 2013.
Supplemental Plan
The Corporation has a supplemental defined benefit pension plan, the Chemical Financial Corporation Supplemental Pension Plan (Supplemental Plan). The Corporation established the Supplemental Plan to provide payments to certain executive officers of the Corporation, as determined by the Compensation and Pension Committee. At December 31, 2015 and 2014, the only executive officer eligible for benefits under the Supplemental Plan was the Corporation's chief executive officer. The Internal Revenue Code limits both the amount of eligible compensation for benefit calculation purposes and the amount of annual benefits that may be paid from a tax-qualified retirement plan. The Supplemental Plan is designed to provide benefits to which executive officers of the Corporation would have been entitled, calculated under the provisions of the Pension Plan, as if the limits imposed by the Internal Revenue Code did not apply. The Supplemental Plan is an unfunded plan and, therefore, has no assets. The Supplemental Plan's projected benefit obligation was $2.2 million and $2.1 million at December 31, 2015 and 2014, respectively. The Supplemental Plan's accumulated benefit obligation was $1.8 million and $2.0 million at December 31, 2015 and 2014, respectively. Supplemental Plan expense totaled $0.4 million in 2015, $0.3 million in 2014 and $0.2 million in 2013.
Postretirement Plan
The Corporation has a postretirement benefit plan (Postretirement Plan) that provides medical and dental benefits, upon retirement, to a limited number of active and retired employees. The majority of the retirees are required to make contributions toward the cost of their benefits based on their years of credited service and age at retirement. Beginning January 1, 2012, the Corporation amended the Postretirement Plan to extend coverage to employees who were at least age 50 as of January 1, 2012. These employees must also retire at age 60 or older, have at least twenty-five years of service with the Corporation and be participating in the active employee group health insurance plan in order to be eligible to participate in the Corporation's Postretirement Plan. Eligible employees may also cover their spouse until age 65 as long as the spouse is not offered health insurance coverage through his or her employer. Employees and their spouses eligible to participate in the Postretirement Plan will be required to make contributions toward the cost of their benefits upon retirement, with the contribution levels designed to cover the projected overall cost of these benefits over the long-term. Retiree contributions are generally adjusted annually. The accounting for these postretirement benefits anticipates changes in future cost-sharing features such as retiree contributions, deductibles, copayments and coinsurance. The Corporation reserves the right to amend, modify or terminate these benefits at any time.
401(k) Savings Plan
The Corporation's 401(k) Savings Plan provides an employer match, in addition to a 4% contribution for employees who are not grandfathered under the Pension Plan discussed above. The 401(k) Savings Plan is available to all regular employees and provides employees with tax deferred salary deductions and alternative investment options. The Corporation matches 50% of the participants' elective deferrals on the first 4% of the participants' base compensation up to the maximum amount allowed under the Internal Revenue Code. The 401(k) Savings Plan provides employees with the option to invest in the Corporation's common stock. The Corporation's match under the 401(k) Savings Plan was $1.6 million in 2015, $1.0 million in 2014 and $1.1 million in 2013. Employer contributions to the 401(k) Savings Plan for the 4% benefit for employees who are not grandfathered under the Pension Plan totaled $3.1 million in 2015, $2.3 million in 2014 and $2.3 million in 2013. The combined amount of the employer match and 4% contribution to the 401(k) Savings Plan totaled $4.7 million in 2015, $3.3 million in 2014 and $3.4 million in 2013.
Multi-Employer Defined Benefit Plan
In conjunction with the April 1, 2015 acquisition of Monarch, the Corporation acquired a participation in the Pentegra Defined Benefit Plan for Financial Institutions (Pentegra DB plan), a qualified defined benefit plan. Employee benefits for Monarch

114

employees under the Plan were frozen effective April 1, 2004. The Pentegra DB Plan operates as a multi-employer plan for accounting purposes and as a multiple employer plan under the Employee Retirement Income Security Act of 1974 and the Internal Revenue Code (IRC). The Pentegra DB Plan is a single plan under IRC Section 413(c) and, as a result, all the plan's assets stand behind all of the plan's liabilities. Accordingly, contributions made by a participating employer may be used to provide benefits to participants of other participating employers. Contributions made by the Corporation to the Pentegra DB Plan during 2015 totaled less than $0.1 million.
The Pentegra DB Plan's Employer Identification Number is 13-5645888 and the Plan Number is 333. Financial information for the Pentegra DB Plan, which maintains a June 30 year end, is made available through the public Form 5500 which is available by April 15th of the year following the plan year end. The Pentegra DB Plan was at least 80% funded as of its most recent year end. The Corporation's allocation of assets and liabilities in the Pentegra DB Plan totaled $3.7 million and $2.6 million, respectively, as of the plan's most recent year end, and the Corporation's allocation of assets comprised less than 5% of the plan's total assets at that date.

The decreases in the projected and accumulated benefit obligations of the Pension Plan during 2015 were primarily attributable to an increase in the discount rate used to value these benefit obligations and an increase in the retirement age assumptions. The Corporation did not make a contribution to the Pension Plan in either 2015 or 2014. The Corporation contributed $15.0 million to the Pension Plan in 2013. The Corporation is not required to make a contribution to the Pension Plan in 2016.

For measurement purposes for the Postretirement Plan, the annual rates of increase in the per capita cost of covered health care benefits and dental benefits for 2016 were each assumed at 7.5%. These rates were assumed to decrease gradually to 5.0% in 2020 and remain at that level thereafter.
The assumed health care and dental cost trend rates could have a significant effect on the amounts reported for the Postretirement Plan. A one percentage-point change in these rates would have the following effects:

Pension Plan Assets
The assets of the Pension Plan are invested by the Wealth Management department of Chemical Bank. The investment policy and allocation of the assets of the pension trust were approved by the Compensation and Pension Committee of the board of directors of the Corporation.
The Pension Plan's primary investment objective is long-term growth coupled with income. In consideration of the Pension Plan's fiduciary responsibilities, emphasis is placed on quality investments with sufficient liquidity to meet benefit payments and plan expenses, as well as providing the flexibility to manage the investments to accommodate current economic and financial market conditions. To meet the Pension Plan's long-term objective within the constraints of prudent management, target ranges have been set for the three primary asset classes: an equity securities range from 40% to 70%, a debt securities range from 20% to 60%, and a cash and cash equivalents and other range from 0% to 10%. Modest asset positions outside of these targeted ranges may occur due to the repositioning of assets within industries or other activity in the financial markets. Equity securities are primarily comprised of both individual securities and equity-based mutual funds, invested in either domestic or international markets. The stocks are diversified among the major economic sectors of the market and are selected based on balance sheet strength, expected earnings

116

growth, the management team and position within their industries, among other characteristics. Debt securities are comprised of U.S. dollar denominated bonds issued by the U.S. Treasury, U.S. government agencies and investment grade bonds issued by corporations. The notes and bonds purchased are primarily rated A or better by the major bond rating companies from diverse industries.

NOTE 17 — SHARE-BASED COMPENSATION
The Corporation maintains a share-based compensation plan, under which it periodically grants share-based awards for a fixed number of shares to certain officers of the Corporation. The fair value of share-based awards is recognized as compensation expense over the requisite service or performance period. During the years ended December 31, 2015, 2014 and 2013, share-based compensation expense related to stock options, restricted stock units and other share-based awards totaled $3.7 million, $2.9 million and $2.9 million, respectively.
During the year ended December 31, 2015, the Corporation granted options to purchase 244,165 shares of common stock, 85,645 restricted stock units and 12,059 shares of common stock to certain officers of the Corporation. On April 20, 2015, the shareholders of the Corporation approved the Stock Incentive Plan of 2015, which provides for 1,300,000 shares of the Corporation's common stock to be made available for future equity-based awards and canceled the amount of shares available for future grant under prior share-based compensation plans. At December 31, 2015, there were 1,274,477 shares of common stock available for future grants under the Corporation's share-based compensation plan.
Stock Options
The Corporation issues stock options to certain officers. Stock options are issued at the current market price of the Corporation's common stock on the date of grant and expire ten years from the date of grant. Stock options granted after 2012 vest ratably over a five-year period. Stock options granted prior to 2013 generally vest ratably over a three-year period.

The intrinsic value of all outstanding in-the-money stock options and exercisable in-the-money stock options was $7.6 million and $4.9 million, respectively, at December 31, 2015. The aggregate intrinsic values of outstanding and exercisable options at December 31, 2015 were calculated based on the closing market price of the Corporation's common stock on December 31, 2015 of $34.27 per share less the exercise price. Options with intrinsic values less than zero, or "out-of-the-money" options, were not included in the aggregate intrinsic value reported.
At December 31, 2015, unrecognized compensation cost related to stock options totaled $3.3 million. This cost is expected to be recognized over a remaining weighted average period of approximately 3.5 years.

The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant and the expected life of the options granted. Expected stock volatility was based on historical volatility of the Corporation's common stock over a seven-year period. The expected life of options represents the period of time that options granted are expected to be outstanding and is based primarily upon historical experience, including option exercise behavior.
Because of the unpredictability of the assumptions required, the Black-Scholes (or any other valuation) model is incapable of accurately predicting the Corporation's common stock price or of placing an accurate present value on options to purchase its stock. In addition, the Black-Scholes model was designed to approximate value for types of options that are very different from those issued by the Corporation. In spite of any theoretical value that may be placed on a stock option grant, no value is possible under options issued by the Corporation without an increase in the market price per share of the Corporation's common stock over the market price per share of the Corporation's common stock at the date of grant.

120

Restricted Stock Units
In addition to stock options, the Corporation also grants restricted stock performance units and restricted stock service-based units (collectively referred to as restricted stock units) to certain officers. The restricted stock performance units vest based on the Corporation achieving certain performance target levels and the grantee completing the requisite service period. The restricted stock performance units are eligible to vest from 0.25x to 1.5x the number of units originally granted depending on which, if any, of the performance target levels are met. However, if the minimum performance target levels are not achieved, no shares will become vested or be issued for that respective year's restricted stock performance units. The restricted stock service-based units vest upon satisfaction of a service condition. Upon achievement of the performance target level and/or satisfaction of a service condition, if applicable, the restricted stock units are converted into shares of the Corporation's common stock on a one-to-one basis. Compensation expense related to restricted stock units is recognized over the expected requisite performance or service period, as applicable.

NOTE 18 — FEDERAL INCOME TAXES
The provision for federal income taxes was less than that computed by applying the federal statutory income tax rate of 35% to pre-tax income, primarily due to tax-exempt interest income on investment securities and loans and income tax credits during 2015, 2014 and 2013. The differences between the provision for federal income taxes computed at the federal statutory income tax rate and the amounts recorded in the consolidated financial statements were as follows:

Management expects to realize the full benefits of the deferred tax assets recorded at December 31, 2015. The Corporation had no reserve for contingent income tax liabilities recorded at December 31, 2015 and 2014. The tax periods open to examination by the Internal Revenue Service include the years ended December 31, 2015, 2014, 2013 and 2012.

Upon the Corporation's acquisition of Monarch, there was an ownership change within the meaning of Internal Revenue Code Section 382. At April 1, 2015, Monarch had $22.6 million in gross federal net operating loss carryforwards that expire between 2028-2034, which the Corporation expects to utilize. The Corporation expects to utilize these net operating losses, in part, as Monarch was in a net unrealized built-in gain position as of the acquisition date. The Corporation had remaining gross federal net operating loss carryforwards of $20.4 million at December 31, 2015.
NOTE 19 — COMMITMENTS AND CONTINGENCIES
In the normal course of business, the Corporation enters into various transactions with its customers, which are not included in its consolidated statements of financial condition. These transactions include unused commitments to extend credit, standby letters of credit and approved but undisbursed loans (undisbursed loan commitments). Unused commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the loan contract. Unused commitments to extend credit generally have fixed expiration dates or other termination clauses. Historically, the majority of the unused commitments to extend credit of Chemical Bank have not been drawn upon and, therefore, may not represent future cash requirements. Standby letters of credit are conditional commitments issued by Chemical Bank to generally guarantee the performance of a customer to a third party. Both arrangements have credit risk essentially the same as that involved in making loans to customers and are subject to the Corporation's normal credit policies, including underwriting standards and ongoing review and monitoring. Collateral obtained upon exercise of commitments is determined using management's credit evaluation of the borrowers and may include real estate, business assets, deposits and other items. Undisbursed loan commitments are not included in loans on the consolidated statements of financial position. The majority of undisbursed loan commitments will be funded and convert to a portfolio loan within a three-month period.
At December 31, 2015, total unused commitments to extend credit, standby letters of credit and undisbursed loan commitments were $1.59 billion, $39 million and $294 million, respectively. At December 31, 2014, total unused commitments to extend credit, standby letters of credit and undisbursed loan commitments were $1.08 billion, $41 million and $251 million, respectively. A significant portion of the unused commitments to extend credit and standby letters of credit outstanding as of December 31, 2015 expire one year from their contract date; however, $144 million of unused commitments to extend credit extend for more than five years.
The Corporation's unused commitments to extend credit and standby letters of credit have been estimated to have an immaterial realizable fair value, as historically the majority of these commitments have not been drawn upon and generally Chemical Bank does not receive fees in connection with these agreements. At both December 31, 2015 and December 31, 2014, the Corporation determined that there were no potential losses from standby letters of credit, and therefore, no reserve was needed at those dates.
Undisbursed loan commitments of $294 million at December 31, 2015 included $23 million of residential mortgage loans that were expected to be sold in the secondary market. The Corporation locked the interest rate to the customer (mortgage loan commitment) on the $23 million of loans that were expected to be sold in the secondary market and entered into best efforts forward contracts with the secondary market on these mortgage loan commitments at December 31, 2015. Best efforts forward contracts offset the interest rate risk of market interest rates changing between the date the interest rate is locked with the customer and the date the loan is sold in the secondary market. At December 31, 2014, the Corporation had mortgage loan commitments of $24 million included in loan commitments, with best efforts forward contracts on these loans at that date.
The Corporation has operating leases and other noncancelable contractual obligations on buildings, equipment, computer software and other expenses that will require annual payments through 2034, including renewal option periods for those building leases that the Corporation expects to renew. Minimum payments due in each of the next five years and thereafter are as follows: 2016 - $14.8 million; 2017 - $12.2 million; 2018 - $6.4 million; 2019 - $3.9 million; 2020 - $2.4 million; 2021 and thereafter - $9.2 million. Minimum payments include estimates, where applicable, of estimated usage and annual Consumer Price Index increases of approximately 3%. Total expense recorded under operating leases and other noncancelable contractual obligations was $15.6 million in 2015, compared to $12.4 million in 2014 and $11.6 million in 2013.
The Corporation and Chemical Bank are subject to certain legal actions arising in the ordinary course of business. In the opinion of management, after consulting with legal counsel, the ultimate disposition of these matters is not expected to have a material adverse effect on the financial position or results of operations of the Corporation.

123

NOTE 20 — REGULATORY CAPITAL AND RESERVE REQUIREMENTS
Banking regulations require that banks maintain cash reserve balances in vault cash, with the FRB, or with certain other qualifying banks. The aggregate average amount of the regulatory balances required to be maintained by Chemical Bank was $65.3 million during 2015 and $46.3 million during 2014. During 2015, Chemical Bank satisfied its regulatory reserve requirements by maintaining a combination of vault cash balances and cash held with the FRB in excess of regulatory reserve requirements. Chemical Bank was not required to maintain compensating balances with correspondent banks during 2015 or 2014.
Federal and state banking regulations place certain restrictions on the transfer of assets, in the form of dividends, loans or advances, from Chemical Bank to the Corporation. At December 31, 2015, substantially all of the assets of Chemical Bank were restricted from transfer to the Corporation in the form of loans or advances. Dividends from Chemical Bank are the principal source of funds for the Corporation. During 2015, 2014 and 2013, Chemical Bank paid dividends to the Corporation totaling $56.9 million, $64.5 million and $24.5 million, respectively. At December 31, 2015, Chemical Bank was "well-capitalized" as defined by federal banking regulations. In addition to the statutory limits, the Corporation considers the overall financial and capital position of Chemical Bank prior to making any cash dividend decisions.
The Corporation and Chemical Bank are subject to various regulatory capital requirements administered by federal banking agencies. Under these capital requirements, Chemical Bank must meet specific capital guidelines that involve quantitative measures of assets and certain off-balance sheet items as calculated under regulatory accounting practices. In addition, capital amounts and classifications are subject to qualitative judgments by regulators. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Corporation's consolidated financial statements.
Quantitative measures established by regulation to ensure capital adequacy require minimum ratios of Tier 1 capital to average assets (Leverage Ratio) and Tier 1 and Total capital to risk-weighted assets. These capital guidelines assign risk weights to on- and off- balance sheet items in arriving at total risk-weighted assets. Minimum capital levels are based upon the perceived risk of various asset categories and certain off-balance sheet instruments. Risk-weighted assets for the Corporation and Chemical Bank totaled $7.14 billion and $7.13 billion, respectively, at December 31, 2015, compared to $5.70 billion for both the Corporation and Chemical Bank at December 31, 2014.
In July 2013, the Federal Reserve Board and Federal Deposit Insurance Corporation (FDIC) approved final rules implementing the Basel Committee on Banking Supervision's (BCBS) capital guidelines for U.S. banks (commonly referred to as Basel III). Beginning January 1, 2015, the Basel III capital rules include a new minimum common equity Tier 1 capital to risk-weighted assets (CET) ratio of 4.5%, in addition to raising the minimum ratio of Tier 1 capital to risk-weighted assets from 4.0% to 6.0% and requiring a minimum leverage ratio of 4.0%. The Basel III capital rules also establish a new capital conservation buffer of 2.5% of risk-weighted assets, which is phased-in over a four-year period beginning January 1, 2016.
At December 31, 2015 and 2014, Chemical Bank's capital ratios exceeded the quantitative capital ratios required for an institution to be considered "well-capitalized." Significant factors that may affect capital adequacy include, but are not limited to, a disproportionate growth in assets versus capital and a change in the mix or credit quality of assets.

124

The summary below compares the Corporation's and Chemical Bank's actual capital amounts and ratios with the quantitative measures established by regulation to ensure capital adequacy. Amounts as of December 31, 2015 were based on the Basel III capital rules, which became effective January 1, 2015. Amounts as of December 31, 2014 were based on the regulatory capital rules in effect as of that date.

NOTE 21 — EARNINGS PER COMMON SHARE
Basic earnings per common share for the Corporation is computed by dividing net income by the weighted average number of common shares outstanding during the period. Basic earnings per common share excludes any dilutive effect of common stock equivalents.
Diluted earnings per common share for the Corporation is computed by dividing net income by the sum of the weighted average number of common shares outstanding and the dilutive effect of common stock equivalents using the treasury stock method. Average shares of common stock for diluted net income per common share include shares to be issued upon the exercise of stock options granted under the Corporation's share-based compensation plans, restricted stock units that may be converted to stock, stock to be issued under the deferred stock compensation plan for non-employee directors and stock to be issued under the stock purchase plan for non-employee community advisory directors. For any period in which a net loss is recorded, the assumed exercise of stock options, restricted stock units that may be converted to stock and stock to be issued under the deferred stock compensation plan and the stock purchase plan would have an anti-dilutive impact on the net income per common share and thus would be excluded in the diluted earnings per common share calculation.
The following summarizes the numerator and denominator of the basic and diluted earnings per common share computations:

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure.
None.
Item 9A. Controls and Procedures.
Disclosure Controls and Procedures
The Corporation's management is responsible for establishing and maintaining effective disclosure controls and procedures, as defined under Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934 (Exchange Act). An evaluation was performed under the supervision and with the participation of the Corporation's management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the Corporation's disclosure controls and procedures as of the end of the period covered by this report. Based on and as of the time of that evaluation, the Corporation's management, including the Chief Executive Officer and Chief Financial Officer, concluded that the Corporation's disclosure controls and procedures were effective to ensure that information required to be disclosed by the Corporation in the reports it files or submits under the Exchange Act is recorded, processed, summarized, and reported, within the time periods specified in the Commission's rules and forms.
Disclosure controls and procedures are designed to ensure that information required to be disclosed by the Corporation in reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms. Disclosure controls are also designed with the objective of ensuring that such information is accumulated and communicated to the Corporation's management, including the Chief Executive Officer and Chief Financial Officer, to allow for timely decisions regarding required disclosure. The Corporation's disclosure controls also include internal controls that are designed to provide reasonable assurance that transactions are properly authorized, assets are safeguarded against unauthorized or improper use and that transactions are properly recorded and reported.
Changes in Internal Controls Over Financial Reporting
There were no changes to the Corporation's internal controls over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) during the quarter ended December 31, 2015 that materially affected, or are reasonably likely to materially affect, the Corporation's internal controls over financial reporting.

MANAGEMENT'S ASSESSMENT AS TO THE EFFECTIVENESS
OF INTERNAL CONTROL OVER FINANCIAL REPORTING

Management of the Corporation is responsible for establishing and maintaining effective internal control over financial reporting that is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles. The system of internal control over financial reporting as it relates to the financial statements is evaluated for effectiveness by management and tested for reliability through a program of internal audits. Actions are taken to correct potential deficiencies as they are identified. Any system of internal control, no matter how well designed, has inherent limitations, including the possibility that a control can be circumvented or overridden and misstatements due to error or fraud may occur and not be detected. Also, because of changes in conditions, internal control effectiveness may vary over time. Accordingly, even an effective system of internal control will provide only reasonable assurance with respect to financial reporting and financial statement preparation.
Management assessed the Corporation's system of internal control over financial reporting as of December 31, 2015, as required by Section 404 of the Sarbanes-Oxley Act of 2002. Management's assessment is based on the criteria for effective internal control over financial reporting as described in "Internal Control — Integrated Framework (2013)" issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this assessment, management has concluded that, as of December 31, 2015, its system of internal control over financial reporting was effective and meets the criteria of the "Internal Control — Integrated Framework (2013)." The Corporation's independent registered public accounting firm that audited the Corporation's consolidated financial statements included in this annual report has issued an attestation report on the Corporation's internal control over financial reporting as of December 31, 2015.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders
Chemical Financial Corporation:
We have audited Chemical Financial Corporation's internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Chemical Financial Corporation's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Assessment as to the Effectiveness of Internal Control over Financial Reporting. Our responsibility is to express an opinion on Chemical Financial Corporation's internal control over financial reporting based on our audit.
We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
In our opinion, Chemical Financial Corporation maintained, in all material respects, effective internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated statements of financial position of Chemical Financial Corporation and subsidiaries as of December 31, 2015 and 2014, and the related consolidated statements of income, comprehensive income, changes in shareholders' equity, and cash flows for each of the years in the three-year period ended December 31, 2015, and our report dated February 26, 2016 expressed an unqualified opinion on those consolidated financial statements.
