Letter to Stockholders

Thomas A. Fanning
Chairman, President and Chief Executive Officer


We believe Southern Company is solidly positioned to deliver on its value proposition as our customer- and community-focused business model continues to serve us well.

Dear Fellow Stockholders:

You are invited to attend the 2018 Annual Meeting of Stockholders at 10:00 a.m., ET, on Wednesday, May 23, 2018, at The Lodge Conference Center at Callaway Gardens, Pine Mountain, Georgia, where we will discuss, among other things, Southern Company’s 2017 performance.

In 2017, our transmission system recorded the best operational performance in Southern Company’s history, with fewer outages and faster response times than ever before. We expanded automation and communication throughout the system with the installation of fiber networks that function to enhance flexibility in serving load and improve reliability. We also continued our track record of outstanding storm response during an especially active hurricane season.

Our generation fleet performed exceptionally well in 2017, with a record low coal burn. In 2005, our use of coal for power generation represented 71% of our fuel mix. This past year, coal represented only 28% of our energy mix. Our gas operations also performed exceptionally well in 2017, as evidenced by Southern Company Gas’ high customer satisfaction results while replacing over 500 miles of aging pipeline infrastructure and continuing the safe and reliable delivery of natural gas.

In 2017, Southern Company was once again recognized by DiversityInc as one of the “Top 50 Companies for Diversity” and number one on its list of “Top 10 Companies for Progress” for the second consecutive year. As I shared with you last year, this recognition is especially significant because it testifies that we are not only a top company for diversity, but we are considered the number one company in America in which those diverse employees are afforded an opportunity to advance their careers.


Diversity and inclusion continue to be key focus areas throughout the Southern Company system. I was pleased in 2017 to join with over 350 other CEOs in signing the CEO Action for Diversity & InclusionTM pledge, committing to cultivate a workplace environment where diverse perspectives are welcomed and employees feel comfortable and valued. Once again, we earned a perfect score from the Human Rights Campaign on their Workplace Equality Index for 2018.

We are taking advantage of the notice and access rules of the Securities and Exchange Commission (SEC) that allow us to furnish our proxy materials to you over the internet instead of mailing paper copies to each stockholder. We are mailing a Notice of Internet Availability of Proxy Materials beginning on or about April 6, 2018 to certain stockholders. The Notice contains instructions on how to access the proxy materials and vote your proxy. A webcast of the Annual Meeting will be available at investor.southerncompany.com, starting at 10:00 a.m., ET, on Wednesday, May 23, 2018. A replay will be available following the meeting.

Your vote is important. We urge you to vote promptly, even if you plan to attend the annual meeting.

Thank you for your continued support of Southern Company.

Letter from the Independent Directors

Dear Fellow Stockholders:

As members of the Board of Directors, we want to thank you for your continued investment in Southern Company. As Directors, we strive to govern Southern Company in a prudent and transparent manner that helps the Company achieve long-term value for you, its stockholders. We proactively oversee business strategy, corporate governance and executive compensation, among other matters. We are pleased to share with you our progress on specific actions undertaken over the past year.

Oversight of Business Strategy

One of our Board’s key responsibilities is overseeing Southern Company’s strategy of maximizing long-term value to stockholders through a customer-, community- and relationship-focused business model anchored by our premier, state-regulated utilities in order to deliver strong and sustainable risk-adjusted returns over time. By focusing on our long-term outlook, we are best able to support our common goal of creating enduring value for customers and stockholders alike.

At each Board meeting and during our strategy planning sessions, we contribute to management’s strategic plan by engaging senior leadership in robust discussions about overall strategy, business priorities and long-term growth opportunities. In particular, in 2017, we focused considerable time on the effects of the bankruptcy filing of the former contractor for Plant Vogtle Units 3 and 4 and on matters related to construction and regulatory recovery of the Kemper County energy facility. Our Board has been and will continue to be committed to the oversight of long-term strategy for the enterprise.

Corporate Governance

This year, we reinforced our commitment to Board governance, Board refreshment and Board succession planning.

During 2017, we engaged a nationally-recognized search firm to assist our search for Board candidates with qualifications, attributes, skills and experiences compatible with our strategic imperatives that drive long-term value. We also engaged an independent outside law firm to conduct a comprehensive review of our corporate governance structure and practices to assist in ensuring the optimal governance structure is in place.

In March 2018, Dr. Ernest Moniz joined our Board as an independent Director. A former United States Secretary of Energy and a distinguished physicist, Dr. Moniz serves on the Operations, Environmental and Safety Committee and the Nominating, Governance and Corporate Responsibility Committee. In addition, he serves on the Business Security Subcommittee, which focuses on cyber and physical risks across the Southern Company system. With this election, we have added four independent Directors over the last four years. We remain focused on continuing to refresh our Board over the coming years.

We appointed Dr. Steven R. Specker to succeed Larry D. Thompson as our Lead Independent Director effective as of the adjournment of the annual meeting on May 23, 2018, assuming Dr. Specker is re-elected.

Letter from the Independent Directors

Executive Compensation

At last year’s annual meeting, the Say on Pay vote did not receive the same high level of support as in previous years. In response, we reached out to stockholders, listened to what they had to say and acted on what we heard. These engagements included active involvement of several of our independent Directors. The message we heard from our stockholders was a concern about the exclusion of 2016 charges to earnings related to the Kemper County integrated gasification combined cycle (Kemper IGCC) facility in determining incentive compensation payouts to our Chief Executive Officer.

In 2017, there were many significant accomplishments and advances for Southern Company, led by the Chief Executive Officer and the executive team. However, in overseeing executive compensation, it is our responsibility to balance the significant Southern Company successes against the ultimate actions taken during 2017 with respect to the Kemper IGCC to ensure that pay is aligned with financial performance and stockholder interests.

Based on the feedback from stockholder engagement, thoughtful consideration by the Compensation and Management Succession Committee and consultation with its independent compensation consultant, the Compensation and Management Succession Committee applied discretion to reduce calculated payouts to the Chief Executive Officer and certain other members of the senior management team for both the annual and long-term incentive awards in 2017. Payout decisions made by the Compensation and Management Succession Committee with respect to the Chief Executive Officer are discussed with and ratified by the independent Directors.

Thank you for the trust you place in us. We value your support, and we encourage you to share your opinions, suggestions and concerns with us. You can do so by writing to us at Southern Company, 30 Ivan Allen Jr. Boulevard NW, Atlanta, Georgia 30308, Attention: Corporate Secretary. You can also send an email to corpgov@southerncompany.com. The email address can also be accessed from the Corporate Governance webpage at investor.southerncompany.com under the link entitled Governance Inquiries.

We are grateful for the opportunity to serve Southern Company on your behalf.

Sincerely,

Juanita Powell Jon A. Henry A. “Hal” David J. Veronica M. Warren A. Linda P.

Proxy Summary

Key Corporate Governance Practices

We seek to establish corporate governance standards and practices that create long-term value for our stockholders and positive influences on the governance of the Company. Our key corporate governance practices include:

Annual election of Directors
Majority voting for Directors, with a Director resignation policy
10% threshold for stockholders to request a special meeting
Proxy access bylaw that provides stockholders (or a group of up to 20) that have maintained ownership of 3% of shares for three years the ability to nominate the greater of two nominees or 20% of Directors
14 of 15 Director nominees are independent, with an average tenure of independent Directors of seven and one-half years
     
Strong Lead Independent Director
All Board committees are comprised of independent Directors
Annual Board and committee self-evaluations
Proactive stockholder engagement
Clawback policy under our Omnibus Plan
Strong stock ownership guidelines
Annual long-term and emergency management succession planning review
Anti-hedging and anti-pledging provisions

Recent Governance and Disclosure Highlights

We are committed to enhancing our governance practices each year. Recent governance and disclosure highlights include:

Continued our stockholder engagement efforts with a significant focus on institutional investor and environmental stakeholder outreach
Added four new Directors to the Board and, as of the annual meeting, will have had two Directors retire in the past four years
Enhanced focus on multi-year Board refreshment and Board succession planning
      
Refreshed Corporate Governance Guidelines and committee charters to better reflect Board committee roles and responsibilities
Included a letter from the independent Directors
Adopted a proxy access right for stockholders
Eliminated the “fair price” anti-takeover provision in the Certificate of Incorporation

Item 2 ►   Advisory Vote to Approve Executive Compensation (Say on Pay)

The Board recommends a vote FOR approval of executive compensation.
See page 87 for further information.

 
We believe our compensation program provides the appropriate mix of fixed and at-risk compensation. Our short- and long-term performance-based compensation program ties pay to Company performance, rewards achievement of financial and operational goals and relative total shareholder return (TSR), encourages individual performance that is in line with our long-term strategy, is aligned with stockholder interests and remains competitive with our industry peers.
Over the past year, we engaged with stockholders and listened to what they had to say. Based on this feedback, thoughtful consideration by the Compensation and Management Succession Committee and consultation with its independent compensation consultant, the Compensation and Management Succession Committee applied discretion to reduce 2017 incentive payouts to the CEO and certain members of senior management to ensure pay is aligned with financial performance.

10     Southern Company 2018 Proxy Statement


Table of Contents

Proxy Summary

Compensation Overview

We target the total direct compensation for our executives at market median and place a significant portion of that target compensation “at risk” – subject to achieving both short-term and long-term performance goals.

CEO Target Pay

    74%    
2017 Long-Term Equity Incentive Award
Long-term equity incentive awards are intended to promote long-term success and increase stockholder value by directly tying a substantial portion of total compensation to the achievement of performance goals designed to foster performance, align with stockholder interests and encourage retention of employees.
In 2017, awards were comprised of a Performance Share Program (PSP) award (70% of the target grant value) and a Performance Restricted Stock Unit (PRSU) award (30% of the target grant value).
The 2017 PSP is granted in the form of performance share units that are earned based on the achievement of financial (earnings per share (EPS) and return on equity (ROE)) and market-based (relative TSR) goals over a three-year performance period (2017 to 2019).
The PRSUs have a one-year financial performance goal of cash from operations. If the goal is met, the PSRUs vest one-third each year over three years. If the goal is not met, all PRSUs are forfeited.
100% of the long-term equity incentive awards are performance-conditioned.
         
2017 Annual Cash Incentive Award
 
Awards under our Performance Pay Program (PPP) for 2017 are earned based on the achievement of financial (EPS and business unit net income), operational and individual performance goals intended to drive annual performance that we believe will lead to long-term success for the Company.
15%
         
11% Salary
 
Only the base salary portion of executive compensation is fixed.
 

Stockholder Outreach and Say on Pay Response

At our 2017 annual meeting, we received 62% support for our executive compensation program. While this reflected continued majority support of our program, we were disappointed in the decline in support compared to prior years and wanted to understand the cause.

We regularly communicate with our stockholders to better understand their viewpoints, gather input on our business strategy and execution and obtain feedback regarding other matters of investor interest. Over the past year, we engaged extensively with stockholders and listened to what they had to say about our executive compensation program. We reached out to stockholders representing more than 35% of our outstanding shares and had approximately 45 meetings by telephone or in person with stockholders representing more than 31% of our outstanding shares. The primary concern identified by stockholders that drove last year’s reduction in support was the exclusion of 2016 charges to earnings related to the Kemper IGCC in determining incentive compensation payouts.

Based on this feedback, thoughtful consideration by the Compensation and Management Succession Committee and consultation with the independent compensation consultant, the Compensation and Management Succession Committee applied discretion to reduce 2017 incentive payouts to the CEO and certain other members of senior management to ensure that 2017 pay is aligned with financial performance and stockholder interests. In aggregate, CEO incentive pay was reduced by $4.68 million, reflecting a 40% reduction as compared to the calculated award amounts. This reduction was the equivalent of paying on earnings calculated under Generally Accepted Accounting Principles (GAAP) for the CEO’s incentive awards.

The Board recommends a vote FOR each Director nominee.

Corporate Governance at Southern Company

Southern Company Board

Majority Voting for Directors and Director Resignation Policy

Since 2010, we have had a majority vote standard for Director elections, which requires that a nominee for Director in an uncontested election receive a majority of the votes cast at a stockholder meeting in order to be elected to the Board. The Board believes that the majority vote standard in uncontested Director elections strengthens the Director nomination process and enhances Director accountability.

The Board believes this standard for uncontested elections is a more equitable standard than a plurality vote standard. A plurality vote standard guarantees the election of a Director in an uncontested election; however, a majority vote standard means that nominees in uncontested elections are only elected if a majority of the votes cast are voted in their favor.

We also have a Director resignation policy, which requires any nominee for election as a Director to submit an irrevocable letter of resignation as a condition to being named as such nominee, which would be tendered in the event that nominee fails to receive the affirmative vote of a majority of the votes cast in an uncontested election at a meeting of stockholders. Such resignation would be considered by the Board, and the Board would be required to either accept or reject such resignation within 90 days from the certification of the election results.

Director Independence Standards

No Director will be deemed to be independent unless the Board affirmatively determines that the Director has no material relationship with the Company directly or as an officer, stockholder or partner of an organization that has a relationship with the Company. The Board has adopted categorical guidelines which provide that a Director will not be deemed to be independent if within the preceding three years:

The Director was employed by the Company or the Director’s immediate family member was an executive officer of the Company.
The Director has received, or the Director’s immediate family member has received, during any 12-month period, direct compensation from the Company of more than $120,000, other than Director and committee fees. (Compensation received by an immediate family member for service as a non-executive employee of the Company need not be considered.)
The Director was affiliated with or employed by, or the Director’s immediate family member was affiliated with or employed in a professional capacity by, a present or former external auditor of the Company and personally worked on the Company’s audit.
The Director was employed, or the Director’s immediate family member was employed, as an executive officer of a company where any of the Company’s present executive officers at the same time served on that company’s compensation committee.
The Director is a current employee, or the Director’s immediate family member is a current executive officer, of a company that has made payments to, or received payments from, the Company for property or services in an amount which, in any year, exceeds the greater of $1,000,000 or 2% of that company’s consolidated gross revenues.
The Director or the Director’s spouse serves as an executive officer of a charitable organization to which the Company made discretionary contributions which, in any year, exceeds the greater of $1,000,000 or 2% of the organization’s consolidated gross revenues.

These guidelines are in compliance with the New York Stock Exchange (NYSE) corporate governance rules within its listing standards.

Director Independence Review Process

At least annually, the Board receives a report on all commercial, consulting, legal, accounting, charitable or other business relationships that a Director or the Director’s immediate family members have with the Company and its subsidiaries. This report includes all ordinary course transactions with entities with which the Directors are associated.

The Board determined that the Company and its subsidiaries followed our procurement policies and procedures, that the amounts reported were well under the thresholds contained in the Director independence requirements and that no Director had a direct or indirect material interest in the transactions included in the report.

The Board reviewed all contributions made by the Company and its subsidiaries to charitable organizations with which the Directors are associated. The Board determined that the contributions were consistent with other contributions by the Company and its subsidiaries to charitable organizations and none were approved outside the Company’s normal procedures.

In determining Director independence, the Board considers transactions, if any, identified in the report discussed above that affect Director independence, including any transactions in which the amounts reported were above the threshold contained in the Director independence requirements and in which a Director had a direct or indirect material interest. No such transactions were identified and, as a result, no such transactions were considered by the Board. The Board also considered that, in the ordinary course of the Southern Company system’s business, electricity and natural gas are provided to some Directors and entities with which the Directors are associated on the same terms and conditions as provided to other customers of the Southern Company system.

As a result of its review process, the Board affirmatively determined that 14 of the 15 Directors nominated for re-election are independent. In addition, the Board affirmatively determined that Mr. Hood is independent.

Board Independence

Directors
All Director nominees are independent except the CEO

Thomas A. Fanning, Chairman of the Board, President and CEO of the Company, is an employee and is not independent.

Identifying Nominees for Election to the Board

The Nominating, Governance and Corporate Responsibility Committee, comprised entirely of independent Directors, is responsible for identifying, evaluating and recommending nominees for election to the Board. Final selection of the nominees for election to the Board is within the sole discretion of the Board.

The Board believes that, as a whole, it should have collective knowledge and experience beneficial to our Company and in line with our long-term strategic plans.

The Nominating, Governance and Corporate Responsibility Committee only considers candidates with the highest degree of integrity and ethical standards. The Nominating, Governance and Corporate Responsibility Committee evaluates a candidate’s independence from management, ability to provide sound and informed judgment, history of achievement reflecting superior standards, willingness to commit sufficient time, financial literacy, number of other Board memberships, genuine interest in the Company and a recognition that, as a member of the Board, one is accountable to the stockholders of the Company, not to any particular interest group. In February 2018, Dr. Moniz was recommended by the Nominating, Governance and Corporate Responsibility Committee for nomination for election to the Board and elected to the Board effective March 1, 2018. Dr. Moniz was identified jointly by the Chairman, President and CEO and several of our independent Directors.

The Nominating, Governance and Corporate Responsibility Committee solicits recommendations for candidates for consideration from its current Directors and is authorized to engage third-party advisers to assist in the identification and evaluation of candidates for consideration. In 2017, the Board engaged the services of a nationally-recognized Board search firm to assist with a candidate search based on a talent framework consistent with our leadership mission and aligned with our strategic imperatives that drive long-term value.

Corporate Governance at Southern Company

Qualifications, Attributes, Skills and Experience Desired on the Board

We believe effective oversight comes from a Board that represents a diverse range of experience and perspectives that provides the collective qualifications, attributes, skills and experience necessary for sound governance. The Nominating, Governance and Corporate Responsibility Committee establishes and regularly reviews with the Board the qualifications, attributes, skills and experience that it believes are desirable to be represented on the Board to ensure that they align with the Company’s long-term strategy. The most important of these are described below.

Senior Leadership
We believe Directors with relevant Chief Executive Officer or senior executive experience bring the deep leadership qualifications and skills necessary to execute our strategic imperatives that drive long-term value.

Risk Management
Directors with knowledge or experience in managing and mitigating key risks, including financial, operational, regulatory, environmental, construction and cybersecurity, assist us in effectively managing risk in a rapidly changing environment, which is critical to our success.

Audit/Financial and M&A
Accurate financial reporting and solid auditing are important to us. Our Board includes Directors with considerable experience with public company financial statements and internal controls comparable to the complexity of ours. With major capital projects as a part of our long-term strategic plan, Directors with finance and capital allocation experience continue to be important to our success. We also believe Directors with public company merger, acquisition and disposition experience are particularly essential to the continued integration of our recently-acquired businesses and for the consideration of any potential future opportunities.

Governmental Affairs/Regulatory
Directors with experience in leadership positions within agencies relevant to our industry or in other regulated businesses are key to our ability to maintain respected regulatory relations and our reputation for doing the right thing. As an important component of U.S.-critical infrastructure, Directors with active security clearances and with background and exposure to the asymmetrical cyber and physical threats facing our industry enable us to stay informed about relevant security issues.

Industry/Operations (Electric, Nuclear and Natural Gas)
We are focused on providing clean, safe, reliable and affordable energy to customers. We also continue to work to advance our country’s capability to generate nuclear power and pursue innovations for a clean energy future. To do this, we include Directors on our Board with deep knowledge and experience in the electricity industry and with nuclear energy. We continue to seek opportunities within the midstream through downstream business operations in the natural gas industry and, with our recent acquisition of Southern Company Gas (GAS), we believe it is important to include Directors with natural gas experience. Directors who previously served on the Board of Directors of one of our operating companies also have operations knowledge and experience that is helpful to the Board.

Corporate Governance and Service on Public Company Boards
Our Board includes Directors with experience in corporate governance matters and service on other public company Boards, providing insights into Board management, relations between the Board, the CEO and senior management, as well as Board refreshment, agenda setting and management succession. These insights are critical to the governance of our complex business.

Environmental Regulation and Policy
As a leader in the energy industry, Directors with a deep understanding or experience with the oversight of environmental policy, regulation, risk and business operation matters permit us to lead innovation and to focus on safe and responsible operations.

Major Projects
Directors with oversight or management experience of major capital projects aimed to drive long-term value are particularly desirable as we continue to manage our major capital projects.

Technology/New Economy
The markets for our businesses are ever changing and industry disruptions and technological advances play a significant role in these changes. We believe Directors with experience related to relevant technology innovations, including clean energy solutions, provide insight needed for us to remain nimble and competitive.

Diversity of our Board

While our Corporate Governance Guidelines do not prescribe diversity standards, the Guidelines mandate that the Board as a whole should be diverse. Our Board also believes that diversity is important, as a variety of points of view contributes to a more effective decision-making process.

At most meetings, the Nominating, Governance and Corporate Responsibility Committee evaluates the expertise and needs of the Board to determine the Board’s proper membership and size. As part of this evaluation, the Nominating, Governance and Corporate Responsibility Committee considers aspects of diversity, such as diversity of race, gender and ethnicity. The nominees for Director include three women, representing 20% of our nominees for Director, and three ethnic minorities, representing 20% of our nominees for Director. Overall, 33% of our nominees for Director are diverse. The Nominating, Governance and Corporate Responsibility Committee also considers diversity of age, education, industry, business background and experience in the selection of candidates to serve on the Board.

The Nominating, Governance and Corporate Responsibility Committee assesses the effectiveness of its efforts at pursuing diversity through its evaluations of the Board’s composition.

Diversity of Director Nominees
33% 3 Women
3 Ethnic Minorities

Board Refreshment

The Nominating, Governance and Corporate Responsibility Committee regularly considers the long-term makeup of our Board and how the members of our Board will change over time, including frequent consideration of potential Board candidates. The Board aims to strike a balance between the knowledge that comes from longer-term service on the Board and the new experience and ideas that can come from adding Directors to the Board.

In 2017, the Nominating, Governance and Corporate Responsibility Committee enhanced its focus on Board refreshment to ensure thoughtful deliberation to align the Board’s long-term composition with the Company’s long-term strategy and to effect meaningful Board succession planning. The Nominating, Governance and Corporate Responsibility Committee’s recent actions include the engagement of a nationally-recognized Board search firm, the election of Dr. Moniz and robust discussions about Board succession planning. In the last four years, we have added four independent Directors to our Board and, as of the annual meeting, will have had two Directors retire. The Board is focusing on continuing refreshment over the coming years.

We believe the average tenure for our independent Directors nominees of approximately seven and one-half years reflects the balance the Board seeks between different perspectives brought by longer-serving Directors and new Directors.

Stockholder Recommendation of Board Candidates

Any stockholder may make recommendations for candidates for consideration by the Nominating, Governance and Corporate Responsibility Committee by sending a written statement describing the candidate’s qualifications, relevant biographical information and signed consent to serve. These materials should be submitted in writing to our Corporate Secretary and received by December 7, 2018 for consideration by the Nominating, Governance and Corporate Responsibility Committee as a nominee for election at the 2019 annual meeting. A stockholder recommendation is reviewed in the same manner as candidates identified by the Nominating, Governance and Corporate Responsibility Committee or recommended to the Nominating, Governance and Corporate Responsibility Committee.

Board Structure and Processes

Board Leadership Structure

Our Governance Guidelines allow the independent Directors flexibility to split or combine the Chairman and CEO responsibilities, and the independent Directors annually review our leadership structure to determine the structure that is in the best interest of Southern Company and its stockholders.

The Board believes that its current leadership structure, which has a combined role of Chairman and CEO counterbalanced by a strong independent Board led by a Lead Independent Director and independent Directors chairing each of the Board committees, is most suitable for us at this time and is in the best interest of stockholders because it provides the optimal balance between independent oversight of management and unified leadership.

The combined role of Chairman and CEO is held by Tom Fanning, who is the Director most familiar with our business and industry, including the regulatory structure and other industry-specific matters, as well as being most capable of effectively identifying strategic priorities and leading discussion and execution of strategy.
Independent Directors and management have different perspectives and roles in strategy development. The CEO brings Company-specific experience and expertise, while our independent Directors bring experience, oversight and expertise from outside the Company and its industry.
The Board believes that the combined role of Chairman and CEO promotes the development and execution of our strategy and facilitates the flow of information between management and the Board, which is essential to effective corporate governance.

Role of the Lead Independent Director

The Lead Independent Director is elected by the independent Directors of the Board. At the 2016 annual meeting, Mr. Thompson was elected by the independent Directors to serve as Lead Independent Director from May 25, 2016 until the 2018 annual meeting. At the Board’s February 2018 meeting, the Board elected Dr. Specker, assuming his re-election, to serve as Lead Independent Director effective May 23, 2018.

The Lead Independent Director has the following powers and responsibilities:

Approving the agenda (with the ability to add agenda items) and schedule for Board meetings and information sent to the Board;
Calling and chairing executive sessions of the non-management Directors;
Chairing Board meetings in the absence of the Chairman;
Meeting regularly with the Chairman;
Acting as the principal liaison between the Chairman and the non-management Directors (although every Director has direct and complete access to the Chairman at any time);
Serving as the primary contact Director for stockholders and other interested parties; and
Communicating any sensitive issues to the Directors.

“Our Board is committed to overseeing Southern Company’s long-term strategy as a leader in our industry, a reliable energy provider for customers and a solid investment for our stockholders.”

Larry D. Thompson

Meetings of Non-Management Directors

Non-management Directors meet in executive session without any members of the Company’s management present at each regularly-scheduled Board meeting. These executive sessions promote an open discussion of matters in a manner that is independent of the Chairman and CEO. The Lead Independent Director chairs each of these executive sessions.

Meetings and Attendance

The Board met 11 times in 2017. Our Directors are engaged, as demonstrated by the average Director attendance at all applicable Board and committee meetings in 2017 of 94%. No nominee attended less than 75% of applicable meetings. In 2017, we also conducted informational calls with the Board (nine times), the Finance Committee (five times) and the Audit Committee (three times) on key topics, including status updates on our major capital projects.

All Director nominees are expected to attend the annual meeting of stockholders. All members of the Board serving on May 24, 2017, except Mr. Boscia, attended the annual meeting in 2017.

Engaged Directors
2017 Board and Committee Meeting Attendance

Board and Committee Self-Evaluation Process

Our Board has a robust annual self-evaluation process. Traditionally, the Nominating, Governance and Corporate Responsibility Committee oversees the annual self-assessment process on behalf of the Board. The Board determined that an evaluation of the full Board assisted by a third party was appropriate. The Board engaged the services of an independent third party to facilitate its annual self-assessment. The process involves an interview of each Director and a facilitated discussion with the full Board. The objective is to allow the Directors to share their perspectives and consider necessary adjustments, if any, in response to the collective feedback.

The charter of each committee of the Board also requires an annual performance evaluation, which is overseen by the chair of each committee. In 2017, each committee of the Board conducted its annual self-assessments.

Board Risk Oversight

The Board and its committees have both general and specific risk oversight responsibilities. The Board has broad responsibility to provide oversight of significant risks primarily through direct engagement with management and through delegation of ongoing risk oversight responsibilities to the committees. Any risk oversight that is not allocated to a committee remains with the Board.

At least annually, the Board reviews our risk profile to ensure that oversight of each risk is properly designated to an appropriate committee or the full Board. The charters of the committees and the checklist of agenda items for each committee define the areas of risk for which each committee is responsible for providing ongoing oversight.

Audit Committee
Reviews risks and associated risk management activities related to financial reporting and ethics- and compliance-related matters.
Reviews the adequacy of the risk oversight process and documentation that appropriate enterprise risk management and oversight are occurring. The documentation includes a report that tracks which significant risk reviews have occurred and the committee(s) reviewing such risks. In addition, an overview is provided at least annually of the risk assessment and profile process conducted by Company management.
Receives regular updates from Internal Auditing and quarterly updates as part of the disclosure controls process.
Compensation and Management Succession Committee
Reviews risks and associated risk management activities related to workforce issues.
Reviews the assessment of risks associated with the Company’s employee compensation policies and practices, particularly performance-based compensation, as they relate to risk management practices and/or risk-taking incentives. The review is conducted at least annually and whenever significant changes to any business unit’s compensation practices are under consideration.
Finance Committee
Reviews risks and associated risk management activities related to financial matters of the Company such as financial integrity, major capital investments, dividend policy, financing programs and financial strategy.
Nominating, Governance and Corporate Responsibility Committee
Reviews risks and associated risk management activities related to state and federal regulatory and legislative environment, stockholder activism and environmental, sustainability and corporate social responsibility.
Operations, Environmental and Safety Committee
Reviews risks and associated risk management activities related to significant operations of the Southern Company system such as safety, system reliability, nuclear, gas and other operations, environmental regulation and policy, fuel cost and availability.
Business Security Subcommittee of the Operations, Environmental and Safety Committee focuses on business strategies designed to prevent or address catastrophic business interruption due to physical or cyber attacks or natural disasters.

Each committee provides ongoing oversight for each of our most significant risks designated to it, reports to the Board on their oversight activities and elevates review of risk issues to the Board as appropriate. For each committee, the CEO of the Company has designated a member of executive management as the primary responsible officer for providing information and updates related to the significant risks. These officers ensure that all significant risks identified in the risk profile we develop are reviewed with the Board and/or the appropriate committee(s) at least annually.

Southern Company has a robust enterprise risk management program that facilitates identification, communication and management of the most significant risks throughout the Company within a formalized framework in which risk governance and oversight are largely embedded in existing organizational and control structures. As a part of the governance structure, the Chief Risk Officer is accountable to the CEO and the Board for ensuring that enterprise risk oversight and management processes are established and operating effectively.

Corporate Governance at Southern Company

We believe that our leadership structure supports the risk oversight function of the Board. While we have a combined role of Chairman and CEO, an independent Director chairs each committee and the Chairman and CEO does not serve on any committee. There is regular, open communication between management and the Directors. All Directors are actively involved in the risk oversight function.

Succession Planning and Talent Development

Valuing and developing our people is a strategic priority for our Company. To support this priority, we engage in detailed discussions around succession planning and talent development at all levels within our organization to achieve business results. We have robust discussions and actions that are ongoing throughout the year.

The Compensation and Management Succession Committee oversees the development and implementation of succession plans for senior leadership positions. The process starts with management undertaking a full internal review of performance and development of leaders across the organization. Management presents and discusses with the Compensation and Management Succession Committee its evaluation and recommendations for senior leadership succession regularly throughout the year. The Compensation and Management Succession Committee regularly updates the Board on these discussions. The Compensation and Management Succession Committee is also regularly updated on key talent indicators for the overall workforce, including diversity and inclusion, recruiting and development programs.

The Board annually reviews succession plans for senior management and the CEO, including both a long-term succession plan and an emergency succession plan. To assist the Board, the CEO annually provides his assessment of senior leaders and their potential to succeed at key senior management positions. The evaluation is done in the context of the business strategy with a focus on risk management. The Board meets potential leaders at many levels across the organization through formal presentations and informal events throughout the year.

Communicating with the Board

We encourage stockholders or interested parties to communicate directly with the Company’s Board, the independent Directors or the individual Directors, including the Lead Independent Director.

Communications may be sent to the Board as a whole, to the independent Directors or to specified Directors, including the Lead Independent Director, by regular mail or electronic mail.
Regular mail should be sent to our principal executive offices, to the attention of the Corporate Secretary, Southern Company, 30 Ivan Allen Jr. Boulevard NW, Atlanta, Georgia 30308.
Electronic mail should be directed to corpgov@southerncompany.com. The electronic mail address also can be accessed from the Corporate Governance webpage located under Corporate Governance on our website at investor.southerncompany.com under the link entitled Governance Inquiries.

With the exception of commercial solicitations, all communications directed to the Board or to specified Directors will be relayed to them.

Other Governance Policies and Practices

Certain Relationships and Related Transactions

We have a robust system for identifying potential related person transactions.

Our Audit Committee is responsible for overseeing our Code of Ethics, which includes policies relating to conflicts of interest. The Code of Ethics requires that all employees, officers and Directors avoid conflicts of interest, defined as situations where the person’s private interests conflict, or even appear to conflict, with the interests of the Company as a whole.
We conduct a review of our financial systems to identify potential conflicts of interest and related person transactions.
At least annually, each Director and executive officer completes a detailed questionnaire that asks about any business relationship that may give rise to a conflict of interest and all transactions in which the Company or one of its subsidiaries is involved and in which the executive officer, a Director or a related person has a direct or indirect material interest.
We have a Contract Manual and other formal written procurement policies and procedures that guide the purchase of goods and services, including requiring competitive bids for most transactions above $10,000 or approval based on documented business needs for sole sourcing arrangements.

The approval and ratification of any related person transaction would be subject to these written policies and procedures which include:

a determination of the need for the goods and services;
preparation and evaluation of requests for proposals by supply chain management;
the writing of contracts;
controls and guidance regarding the evaluation of the proposals; and
negotiation of contract terms and conditions.

As appropriate, these contracts are also reviewed by individuals in the legal, accounting and/or risk management/ services departments prior to being approved by the responsible individual. The responsible individual will vary depending on the department requiring the goods and services, the dollar amount of the contract and the appropriate individual within that department who has the authority to approve a contract of the applicable dollar amount.

We do not have a written policy pertaining solely to the approval or ratification of related person transactions.

In 2017, Ms. Alexia B. Borden, the daughter of Paul Bowers, an executive officer of the Company, was employed by Alabama Power as vice president with responsibility for Governmental Affairs until November 2017 when she was appointed senior vice president and general counsel and received total compensation of $502,703, as calculated in accordance with SEC rules and regulations.

We do not have any other related person transactions that meet the requirements for disclosure in this proxy statement.

In the ordinary course of the Southern Company system’s business, electricity and natural gas are provided to some Directors and entities with which the Directors are associated on the same terms and conditions as provided to other customers of the Southern Company system.

Proxy Access

Proxy access generally refers to the right of stockholders who meet certain ownership thresholds to nominate one or more Directors to the Board and have the nominees included in the Company’s proxy materials and on the Company’s proxy card.

In 2015, a stockholder submitted a proposal to adopt proxy access. The proposal was not approved by stockholders at the 2015 annual meeting. Given the level of stockholder support for the proposal and the Board’s ongoing review of best corporate governance practices, the Board continued to discuss the possibility of adopting proxy access after the 2015 annual meeting.

At the 2016 annual meeting, the Board proposed for stockholder vote a proxy access amendment to our By-Laws. The Board’s decision was the result of feedback from stockholder outreach, including the proponent of the proxy access proposal, consideration of evolving corporate governance trends and continuous review of our corporate governance practices. The Board believed that the By-Law amendment provided meaningful rights to stockholders while promoting responsible use of these rights by stockholders.

The proposed amendment received overwhelming support (over 95%) from our stockholders at the 2016 annual meeting and was adopted in May 2016. The following are the key terms of the proxy access By-Law amendment:

                                                                                            
                                                                                   
Any stockholder or group of up to 20 stockholders maintaining continuous qualifying ownership of at least 3% of our outstanding shares for at least 3 years

Can nominate, and include in our proxy materials, Director nominees constituting the greater of 2 nominees or 20% (rounded down) of the number of Directors in our proxy materials for the next annual meeting

Nominating stockholder(s) and the nominee(s) must also meet the eligibility requirements in Section 47 of our By-Laws.

Stockholder Engagement

We place great importance on consistent dialogue with all our stakeholders, including customers, employees and stockholders. We regularly engage in discussions with, and provide comprehensive information for, constituents interested in the Southern Company system’s citizenship, stewardship and environmental compliance. We are receptive to stakeholder concerns, and we are committed to transparency and proactive interactions with our investors. We regularly communicate with our stockholders to better understand their viewpoints, gather input on our business strategy and execution and obtain feedback regarding other matters of investor interest.

Our management team participates in numerous investor meetings each year to discuss our business, our strategy and our financial results. These meetings include in-person, telephone and webcast conferences.
Since 2011, we have held regular environmental stakeholder forums, webinars, calls and meetings covering a range of topics, including regulatory and policy issues, system risk and planning related to renewables, energy efficiency and greenhouse gas matters. Members of senior management participate in these events.
We began a more systematic approach to stockholder outreach with respect to environmental, social, governance and executive compensation topics in 2014 that involved members of our senior management. The stockholder outreach team expanded in 2016 to include independent Directors. The Nominating, Governance and Corporate Responsibility Committee currently oversees the stockholder engagement program on behalf of the Board.

Outreach Over the Last Year

In 2017 and early 2018, we reached out to our 100 largest stockholders representing more than 35% of our outstanding shares and requested meetings to discuss executive compensation, environmental, social and governance topics, as well as any other topics of interest. We also reached out to stockholders that are not among our 100 largest but expressed an interest in engaging with us. We received positive responses from, and had approximately 45 meetings by telephone or in person with, stockholders representing more than 31% of our outstanding shares, including index funds, union and public pension funds, actively-managed funds and socially-responsible investment funds. We also engaged with the two largest proxy advisory firms.

Participants in calls and meetings with our largest stockholders included one or more independent Directors (Lead Independent Director, Chair of our Nominating, Governance and Corporate Responsibility Committee and/or Chair of our Compensation and Management Succession Committee), the CEO (only where the call did not include a discussion of executive compensation), the Chief Financial Officer (CFO), the General Counsel and the Chief Human Resources Officer. Stockholder feedback is reported to our Nominating, Governance and Corporate Responsibility Committee, Compensation and Management Succession Committee and Operations, Environmental and Safety Committee, as appropriate, throughout the year.

Response to 2017 Stockholder Proposal

At the 2017 annual meeting, a stockholder proposal from the Sisters of St. Dominic of Caldwell New Jersey and certain colleagues at the Interfaith Center on Corporate Responsibility requesting a report on the Company’s strategy related to the International Energy Agency 2°C scenario received 46% support. Although the proposal did not pass, we began working with the proponents on disclosures responsive to the proposal. Over the past year, we have had a number of collaborative and constructive in-person meetings and telephone conferences with the proponents to discuss the proposal and our report. We anticipate publishing on our website under the link entitled Corporate Responsibility a report that is responsive to the proposal prior to the date of the 2018 annual meeting.

Political Contributions Policy

We believe that we have a responsibility to customers and stockholders to participate in the political process and, where appropriate, to make political contributions or expenditures (as defined by applicable law). The Company and its subsidiaries comply with all laws governing the use of corporate funds in connection with elections for public office. All political contributions or independent expenditures must be approved in advance by the CEO, the senior External Affairs Officer and the General Counsel (if applicable) of the Southern Company entity making the disbursement.

The Company’s political expenditures are reviewed at least annually by the Southern Company Board of Directors.

Our Responsibility

The Southern Company system is committed to developing the full portfolio of generation resources, including carbon-free nuclear, natural gas, renewables, energy efficiency and storage technology. With an industry-leading commitment to research and development, we have managed more than $2 billion in research and development investments and are at the forefront of technology development for the production, delivery and use of energy.

Our greatest asset in this effort is our employees. Our workforce is engaged in cultivating and leveraging this inventive mindset. We are collaborating with forward-looking companies and seeking partnerships with the brightest minds, leading universities and cutting-edge research organizations.

We continually strive to reduce the environmental impact of our operations, help customers use energy more wisely and conserve natural resources. The Southern Company system's commitment to the environment has been demonstrated in many ways, including:

participating in partnerships resulting in approximately $126 million of funding that has restored or enhanced more than 1.7 million acres of habitat since 2003;
removal of more than 15 million pounds of trash and debris from waterways through the Renew Our Rivers program;
a 21% reduction in surface water withdrawal from 2015 to 2016;
reductions in sulfur dioxide and nitrogen oxide air emissions of 95% and 85%, respectively, since 1990;
a reduction of mercury air emissions of over 90% since 2005; and
the Southern Company system's changing energy mix that has continued to reduce greenhouse gas emissions.

Through 2017, the traditional electric operating companies have also invested approximately $12.9 billion in environmental capital retrofit projects to comply with environmental requirements.

We are active members of the communities we serve. As evidence of this commitment, employees consistently give more than 200,000 hours of volunteer community service annually and help lead economic development efforts.

To learn more about the Company's corporate responsibility efforts, please view our Corporate Responsibility Report and other environmental documents by visiting http://www.southerncompany.com/corporate-responsibility/report-parameters.html.

Director Compensation

Only non-employee Directors of the Company are compensated for service on the Board. In October 2017, the Nominating, Governance and Corporate Responsibility Committee engaged Pay Governance to provide an independent assessment of the current non-employee director compensation program to ensure continued alignment with comparable companies and sound governance practices. The Nominating, Governance and Corporate Responsibility Committee last obtained a market assessment of the program in 2015.

Pay Governance reported that the Company’s current program provides total direct compensation (retainer plus equity) between the 50th and 75th percentile of utility peers and below the 50th percentile of a broad group of general industry companies. Based on this assessment, the Nominating, Governance and Corporate Responsibility Committee did not recommend any changes to the program.

For 2017, the pay components for non-employee Directors were:

Annual cash retainers   
Cash retainer $ 110,000
Additional cash retainer if serving as the Lead Independent Director of the Board $ 30,000
Additional cash retainer if serving as a chair of a committee of the Board $ 20,000
Additional cash retainer if serving on the Business Security Subcommittee of the Operations, Environmental and Safety Committee $ 12,500
Annual equity grant
In deferred common stock units until Board membership ends $ 140,000

Corporate Governance at Southern Company

Director Stock Ownership Guidelines

Under our Corporate Governance Guidelines, non-employee Directors are required to beneficially own, within five years of their initial election to the Board, common stock of the Company equal to at least five times the annual cash retainer. The annual equity grant for non-employee Directors is required to be deferred until Board membership ends. All non-employee Directors either meet the stock ownership guideline or are expected to meet the guideline within the allowed timeframe.

Director Deferred Compensation Plan

The annual equity grant is required to be deferred in shares of common stock under the Deferred Compensation Plan for Outside Directors of The Southern Company, as amended and restated effective January 1, 2008 (Director Deferred Compensation Plan), and invested in common stock units which earn dividends as if invested in common stock. Earnings are reinvested in additional stock units. Upon leaving the Board, distributions are made in common stock or cash.

In addition, Directors may elect to defer up to 100% of their remaining compensation in the Director Deferred Compensation Plan until membership on the Board ends. Such deferred compensation may be invested as follows, at the Director’s election:

in common stock units which earn dividends as if invested in common stock and are distributed in shares of common stock or cash upon leaving the Board; or

at the prime interest rate which is paid in cash upon leaving the Board.

All investments and earnings in the Director Deferred Compensation Plan are fully vested and, at the election of the Director, may be distributed in a lump-sum payment, or in up to 10 annual distributions after leaving the Board. We have established a grantor trust that primarily holds common stock that funds the common stock units that are distributed in shares of common stock. Directors have voting rights in the shares held in the trust attributable to these units.

Compensation Discussion and Analysis

Letter from the Compensation and Management Succession Committee (Compensation Committee)

To our Fellow Stockholders:

Southern Company’s strategy is to maximize long-term value to stockholders through a customer-, community- and relationship-focused business model that produces sustainable levels of return on energy infrastructure. In 2017, we continued to provide clean, safe, reliable and affordable energy to over nine million retail and wholesale customers. Operating premier state-regulated utilities and investing in energy infrastructure under long-term contracts are the focus of Southern Company’s customer-centric business model, which is designed to support regular, predictable and sustainable long-term earnings and dividend growth. We believe that achieving these objectives will deliver superior long-term risk-adjusted TSR for investors.

We achieved success on multiple fronts over the last year, while also experiencing a regulatory disallowance of the costs of the gasifier at the Kemper IGCC. Some of the highlights include:

Focus on Safety, People and Culture: As we strive to be a premier employer of choice, in 2017 we built on a strong safety culture through improved incident prevention programs, emphasized diversity and, particularly, inclusion and bolstered talent development and our succession pipeline.

Outstanding Operational Performance and Customer Service: 2017 represented one of our strongest operational performances in recent history. We had strong operational performance on electric generation, transmission and distribution, while continuing a stellar track record of outstanding storm response during an active 2017 hurricane season. Our state-regulated electric and gas utilities continue to be among the most highly rated utilities for customer satisfaction by J.D. Power, which ranks companies based on power quality and reliability, price, billing and payment, corporate citizenship, communications and customer service. Southern Company and its four state-regulated electric utilities continued to achieve top five rankings on the Customer Value Benchmark Survey, while two Southern Company Gas subsidiaries were named among the “Most Trusted Brands” in the industry. Southern Power delivered excellent performance with its natural gas and renewable generation assets, including its best ever performance on a key metric for generation availability.

Constructive Regulatory Outcomes: We continued to foster strong regulatory relationships as evidenced by multiple constructive outcomes at our electric and gas utilities.

Progress on Vogtle Construction Project: At Plant Vogtle Units 3 and 4, the first new U.S. nuclear project in three decades, Georgia Power successfully navigated and mitigated the impacts from the March 2017 bankruptcy of the contractor, Westinghouse. Southern Nuclear has successfully assumed control of construction at the site and the Vogtle owners brought nuclear-experienced Bechtel Power Corporation on site as the prime contractor. In September, Georgia Power received an approximately $1.7 billion conditional commitment for incremental Department of Energy (DOE) loan guarantees, which now total $5.13 billion and are expected to save Georgia Power customers over $500 million in costs. Final approval and issuance of the additional loan guarantees cannot be assured. Along with its co-owners, Georgia Power received payment of 100% of its portion (approximately $1.7 billion) of the $3.7 billion Toshiba guarantee obligation, which will mitigate the cost to complete the facility. In December, Georgia Power received unanimous approval to continue construction under the new cost and schedule from the Georgia Public Service Commission. Earlier this year, Congress extended the deadline for receiving advanced nuclear production tax credits providing approximately $1 billion in expected future benefits for Georgia Power customers.

These achievements supported our strong financial results.

Strong Adjusted EPS: Our adjusted EPS outcome for 2017 was at the top of the guidance range we established at the beginning of the year.

Increased Dividend: We increased our dividend by eight cents per share, effective as of the second quarter of 2017. This marked 70 consecutive years – dating back to 1948 – that Southern Company paid a dividend to its stockholders that is equal to or greater than the previous year.

Compensation Discussion and Analysis

However, Southern Company recognized charges to earnings in 2017 for the remaining costs associated with the gasifier at the Kemper IGCC. Consistent with our culture of pay for performance and management accountability, and despite the outstanding performance described above, we exercised discretion to meaningfully reduce incentive payouts for the CEO and other key management responsible for the project.

We believe in pay for performance

We design our compensation program to attract, engage, competitively compensate and retain our employees. We target the total direct compensation for our executives at market median and place a very significant portion of that target compensation at risk – subject to achieving both short-term and long-term performance goals. In fact, only the base salary portion of executive compensation is fixed.

CEO Target Pay

We engaged with stockholders and responded to their feedback

At the 2017 annual meeting, the Say on Pay vote received 62% support, which was a decrease from the average of 93% support we received from 2011 through 2016. We were disappointed with the results of the vote and wanted to understand what drove the decrease in support. In response, we reached out to stockholders representing over 35% of our stock, listened to what they had to say and acted on what we heard. These engagements included active involvement of our independent Directors, and the clear message from our stockholders was concern about the exclusion of 2016 charges to earnings related to the Kemper IGCC in determining incentive compensation payouts.

Consistent with the Company’s earnings press releases, we use adjusted earnings results as a starting point for determining payouts. Adjusted EPS is a primary metric that analysts use to evaluate our financial performance because it is an indicator of the earnings from ongoing business activities. We then review the calculated pay outcome and consider whether the calculated payouts are appropriately aligned with Company financial performance and stockholder interests. To ensure alignment between pay and financial performance, we retain the ability to exercise discretion in determining final payouts under the annual and long-term incentive programs.

In 2017, there were many significant accomplishments and advances for the Company, led by the CEO and the executive team. However, it is our responsibility to balance the significant successes against the ultimate actions taken during 2017, in particular the charges to earnings for the Kemper IGCC, to ensure that pay is aligned with financial performance and stockholder interests.

Based on the feedback from stockholder engagement, thoughtful consideration by our committee and consultation with our independent compensation consultant, we applied discretion to reduce 2017 payouts to the CEO and other members of the senior management team for the annual and long-term incentive awards. We reduced total 2017 incentive pay to the CEO by $4.7 million, reflecting a 40% reduction as compared to the calculated incentive award amounts1. This reduction was the equivalent of paying incentive awards for the CEO on GAAP results.

We reduced the CEO’s calculated payout for the 2017 PPP by 55% or $1.6 million and the calculated payout for the PSP for the 2015 to 2017 performance period by 35% or $3.1 million1. We also held the CEO’s base salary flat for 2018.

We reduced PPP and PSP payouts to certain other members of senior management by an aggregate amount of $2.0 million1.

The Compensation Committee and the other independent Directors believe that our CEO and senior management team are one of the most experienced and capable leadership teams in our industry. However, we believe it to be appropriate to take this step to ensure alignment between financial performance and stockholder interests.

Based on a stock price of $44.68, the closing stock price on the date the Compensation Committee made its decisions about 2017 payouts.

Compensation Discussion and Analysis

As in previous years, stockholders continued to express support for the overall design of the compensation program. We requested input from stockholders on changes we could implement that would further improve program design. Based on this input, thoughtful consideration by our committee and consultation with our independent compensation consultant, we eliminated EPS as a financial performance measure in the 2018 long-term incentive program, so that EPS is not duplicated as a financial performance measure in the 2018 PPP and 2018-2020 PSP. We also reduced the weighting of the CEO’s individual performance component in the 2018 PPP.

Our values drive our social and human capital strategies and are a strategic priority

How we do our work at Southern Company is just as important as what we do. Our employees are our greatest asset, and our actions demonstrate the value we place on our people. We are fully committed to the long-term value that is created by attracting, developing and retaining an engaged, healthy, sustainable and socially responsible workforce, and a robust workforce is a leading indicator of our business performance. Our human capital strategy is integrally linked with our business strategy to drive superior performance and total commitment to our stockholders, customers, employees and the communities where we live and work.

We foster a diverse, inclusive and innovative culture that encourages and embraces change and differences of ideas and perspectives. We fuel this through a robust development environment that is designed to accelerate development for high performers and provide leadership and skill development for all employees. Development and retention of our talent are core to who we are and critical to our ongoing success. Additionally, it helps us create a strong employment brand to attract talent in an increasingly competitive labor market. We invest in the well-being of our employees through a comprehensive compensation and benefits strategy that includes a competitive salary, annual incentive award for nearly all employees and pension and benefits designed to encourage physical, financial and emotional well-being.

Our succession and organization leadership processes are driven by these principles and provide us with a strong and deep bench of leadership for positions, while also affording us the opportunity to attract external talent at all levels to enhance our skills and prepare for the future.

Our committee members are actively engaged

We held eight Compensation Committee meetings during 2017, and the average Director attendance at these meetings in 2017 was 98%. We listened to stockholder feedback from the 2017 Say on Pay vote and responded to what we heard. We are engaged and take our responsibilities seriously in establishing and overseeing the executive compensation program and management succession planning.

We thank you for your continued support.

Report of the Compensation Committee

We met with management to review and discuss the CD&A. Based on that review and discussion, we recommended to the Board that the CD&A be included in this proxy statement.

Compensation Discussion and Analysis

Vogtle Units 3 and 4

Following the bankruptcy of Westinghouse in 2017, on behalf of Georgia Power and the project co-owners, Southern Nuclear assumed control of the site. Since the transition to Southern Nuclear, productivity has improved.

Georgia Power continues to take actions to mitigate risks for customers and stockholders.

Bechtel Power Corporation has been selected as the primary construction contractor to complete the remaining construction activities for Plant Vogtle Units 3 and 4.

Georgia Power and the co-owners have received payment of 100% of Toshiba’s parent guarantee obligation.

A conditional commitment for expanding the DOE loan guarantee program for the project has been received; however, final approval and issuance of the additional loan guarantees by the DOE cannot be assured and are subject to the negotiation of definitive agreements, completion of due diligence by the DOE, receipt of any necessary regulatory approvals and satisfaction of other conditions.

Advanced nuclear production tax credits have been extended.

The Georgia Public Service Commission unanimously approved continuing construction and deemed reasonable the revised Plant Vogtle Units 3 and 4 project cost and schedule estimates, which included an additional $1.6 billion in capital costs, as well as November 2021 and November 2022 in-services dates for Plant Vogtle Units 3 and 4, respectively.

Kemper IGCC

Mississippi Power suspended startup activities on the gasifier portion of the Kemper County energy facility in June 2017 and took a pretax charge to earnings of $2.8 billion in the second quarter of 2017 after determining that recovery of costs associated with the gasifier portion of the facility was unlikely. Several events and factors led to this decision.

Mississippi Power filed an updated economic viability study with the Mississippi Public Service Commission in February 2017 indicating that operating the Kemper IGCC on lignite would be less economic than operating the combined cycle portion of the facility on natural gas in most future scenarios. The primary factor driving this result was an updated natural gas price forecast reflecting lower sustained prices of almost 25% over the long term. In 2008, when the Kemper County energy facility was first proposed, natural gas prices were significantly higher than 2017 prices and had demonstrated significant periods of volatility.

Mississippi Power determined that a critical component, the superheater section of the syngas coolers, would need redesign and replacement sooner than originally expected. Replacement of the superheaters would require lead time for design, fabrication and installation and add to costs. Though Mississippi Power believed it could achieve commercial operations of the gasifier portion of the facility in the near term, this issue diminished the likelihood of achieving sustainable operations using lignite.

The Mississippi Public Service Commission encouraged all parties to reach a rate settlement that included no recovery of any gasifier-related costs and included continued operation of the facility as a natural gas combined cycle facility.

Mississippi Power continues to operate the natural gas combined cycle portion of the Kemper County energy facility as it has since that portion of the facility went into service in 2014. In February 2018, the Mississippi Public Service Commission issued an order approving cost recovery of the natural gas combined cycle portion of the facility, resulting in $1.1 billion of recovery.

Total Shareholder Return

Our goal is to deliver long-term value to our stockholders with appropriate risk-adjusted TSR. In 2017, we delivered a 2.4% annualized return to our stockholders. Over a three-year and five-year period, we delivered a 4.0% and 7.2% annualized return to stockholders, respectively. However, our TSR has underperformed the Philadelphia Utility Index and the S&P 500 over these periods. We believe performance relative to the Philadelphia Utility Index is largely attributable to investor sentiment regarding our major construction projects and, most recently, the implications

of actual and potential federal tax law changes. Relative to the S&P 500, we believe performance is largely attributable to our major construction projects, correlation to interest rate expectations and, most recently, the implications of actual and potential federal tax law changes.

Total Shareholder Return (Annualized)

(as of December 31, 2017)*

On a long-term basis of 25 years, we have outperformed the indices.

Southern Company 2.5% 4.0% 7.2% 11.1%

We believe the actual pay realized by the CEO over the past three years is aligned with our relative TSR performance over the same period.

Stockholder Outreach and Say on Pay Response

From 2011 through 2016, Say on Pay support averaged 93%. In our outreach during that time, we received positive feedback from stockholders regarding our executive compensation program. We did not make any material changes in design or execution to our executive compensation program between 2015 and 2016.

At our 2017 annual meeting, we received 62% support for our executive compensation program. While 2017 results reflected continued majority support of our program, we were disappointed in the decline and wanted to understand the cause.

We regularly communicate with our stockholders to better understand their viewpoints, gather input on our business strategy and execution and obtain feedback regarding other matters of investor interest. Over the past year, we took the opportunity to understand what drove the shift in support for our executive compensation program and to discuss other topics of interest, including environmental, social and governance matters.

Throughout 2017 and early 2018, under the oversight of our independent Directors, we reached out to our 100 largest stockholders representing more than 35% of our outstanding shares and requested meetings to discuss our executive compensation program and any other topics of interest. We also engaged with stockholders that are not among our largest 100 but expressed an interest in engaging with us.

We received positive responses from, and had approximately 45 meetings by telephone or in person with, stockholders representing more than 31% of our outstanding shares.

Participants in calls and meetings with our largest stockholders included one or more independent Directors (Lead Independent Director, Chair of our Compensation Committee and/or Chair of our Nominating, Governance and Corporate Responsibility Committee), the CEO (only where the call did not include a discussion of executive compensation), the CFO, the General Counsel and the Chief Human Resources Officer.

We also engaged with the two largest proxy advisory firms.

The primary concern identified by stockholders that drove the reduction in support for Say on Pay was the exclusion of 2016 charges to earnings related to the Kemper IGCC in determining executive compensation payouts.

Stockholders expressed positive views regarding the Company’s strong and stable executive team and also expressed support for the overall design and structure of the compensation program. Stockholders indicated that it was not the structure of the compensation program that drove the decline in support for Say on Pay. During our conversations, we requested stockholder input on suggestions about the design and structure of the compensation program.

The Compensation Committee also obtained feedback, advice and recommendations on compensation best practices from its independent compensation consultant, Pay Governance.

Compensation Discussion and Analysis

What We Heard

    

What We Did

         

Primary Concern:

Alignment between pay and financial performance for CEO

The Compensation Committee applied discretion to reduce payouts to the CEO for both the 2017 PPP and the 2015-2017 PSP. In aggregate, CEO pay was reduced by $4.68 million, reflecting a 40% reduction as compared to the calculated award amounts. This reduction was the equivalent of paying on earnings calculated under GAAP for the EPS and ROE measures for the CEO’s incentive awards.

Stockholders expressed concern over the 2016 adjustments for Kemper IGCC charges being excluded for pay purposes and the Compensation Committee not using its discretionary authority to align incentive award payouts and financial performance

Other Stockholder Input on Compensation Plan Design:
On overall pay mix (% of pay at risk)
Stockholders support the practice of linking nearly 90% of CEO pay to achievement of performance goals
    
The Compensation Committee continued the overall pay mix that emphasizes at-risk pay.

On benchmark and peer group

Stockholders support the benchmark used and level of pay targeted. Stockholders noted that we could combine disclosure about the peer groups used for setting pay levels and to measure relative TSR.
We combined our disclosure about the two peer groups.

On annual incentive award

Stockholders support the overall PPP design and the use of financial, operational and individual performance measures.
Stockholders liked the flexibility and alignment provided by the individual performance metric in the PPP. However, a few stockholders suggested decreasing the weighting for this metric.
The Compensation Committee continued with the same overall structure of PPP, including financial, operational and individual performance measures.
The Compensation Committee continued using an individual performance measure but reduced the weighting for the CEO and the CFO from 30% to 25% for the 2018 PPP program.

On annual incentive award/long-term incentive award

Stockholders agreed that EPS is an appropriate financial performance measure in our industry. However, a number of stockholders suggested that EPS not be duplicated in both the annual and long-term incentive awards.
The Compensation Committee continued using EPS as a financial performance measure in the PPP. The Compensation Committee eliminated EPS as a financial performance measure in the PSP beginning in 2018.

On long-term incentive award

Stockholders generally support the design of the PSP that includes financial and market-based (relative TSR) measures over a three-year performance period. Stockholders confirmed that they like the use of an ROE measure. A few stockholders would prefer not to have a relative TSR measure, while a number of stockholders expressed support for a relative TSR measure.
Several stockholders suggested having a portion of the long-term incentive award allocated to a time-vesting component, such as restricted stock units (RSUs), to help with annual retention and still provide alignment with stock price performance, as long as a significant majority of the program is performance-based.
The Compensation Committee continued using financial (ROE) and market-based (relative TSR) performance measures in the PSP. We believe relative TSR is an effective measure to evaluate performance against our peers and that the majority of our stockholders believe it is an appropriate measure to be included in a long-term incentive award.
In 2017, the Compensation Committee allocated 30% of the long-term incentive award to PRSUs with a one-year financial performance goal. If the goal is met, the award vests one-third per year over three years. If the goal is not met, the PRSUs are forfeited. We believe this retains the performance-based structure of our program with the introduction of a time-vesting component and balances the perspectives we heard from stockholders. The Compensation Committee continued the 30% allocation to PRSUs with a one-year financial performance goal in 2018.

CEO Pay for Performance Alignment

2017 CEO Incentive Pay Demonstrates Pay for Financial Performance Alignment

To illustrate the link between pay and performance, the chart shows, for the 2017 PPP and the 2015-2017 PSP awards, the target value at grant, the calculated payout (based on the adjusted EPS that we reported in our earnings releases) and the actual payout approved by the Compensation Committee after applying discretion to reduce the payouts. The chart demonstrates the significant reduction to the CEO’s variable incentive pay for short- and long-term performance awards in 2017 of $4.68 million or 40%.

2017 CEO Incentive Pay
($ millions)

Three Year CEO Incentive Payouts Demonstrate Alignment with Stockholder Value

The Summary Compensation Table shows pay calculated in accordance with SEC rules and regulations. Because a significant majority of the pay reported in the table represents the target value of long-term equity incentive awards that are at risk and subject to the achievement of performance goals, much of the reported pay may not ultimately be received by the CEO.

The chart compares CEO target incentive pay to actual incentive payouts for 2015, 2016 and 2017. Over these three years, actual payouts totaled $13.26 million, which was $15.45 million, or 54%, lower than target. Actual CEO pay is aligned with stock price performance and stockholder interests and is consistent with our relative TSR performance as compared to peers over the same time period.

Three Year CEO Incentive Pay
($ millions)

Calculation Details

Target represents target PPP approved by the Compensation Committee and the grant date fair value of the PSP and/or the PRSU awards as reported in the Summary Compensation Table.

Calculated Payout (Before discretion) represents the 2017 PPP and 2015-2017 PSP award as calculated based on the adjusted EPS that we report in our earnings releases before the application of discretion using a stock price of $44.68 per share and including accrued dividend equivalent units (DEUs).

Actual Payout (After discretion) represents the PPP payouts earned for 2015, 2016 or 2017 after the application of discretion, if applicable, and the value of the PSP awards earned for 2013-2015, 2014-2016 or 2015-2017 after the application of discretion, if applicable, using a stock price of $44.68 per share and including accrued DEUs.

Compensation Discussion and Analysis

Compensation Governance Oversight by the Board and its Committees

The Board and its committees are actively engaged in the compensation process to ensure appropriate compensation governance oversight.

Principle Description Application

Collaboration

   
Obtain review and input into financial and operational goals from applicable Board committees
   
The Finance Committee reviews the Company’s financial plan and the proposed compensation program financial goals to ensure that the goals are aligned with the financial plan and are rigorous and provides its input to the Compensation Committee.
The Operations, Environmental and Safety Committee reviews the proposed operational goals compared to industry benchmarks and prior year results and provides its input to the Compensation Committee.

Alignment

The Compensation Committee ensures alignment of financial targets for compensation programs with financial plan and EPS guidance
The Compensation Committee approves an EPS goal that is aligned with the EPS guidance range established at the beginning of the year. In 2017, the guidance range and the EPS goal increased by 5% from 2016.

Analysis and Discretion

Active involvement by the Compensation Committee in ensuring alignment between calculated performance results and payouts under incentive compensation programs
The Compensation Committee receives updates and engages in regular dialogue regarding progress towards goals and impacts to at-risk compensation.
The Compensation Committee carefully considers adjustments to financial goals in light of overall Company performance and retains discretion to adjust payouts up or down to ensure appropriate alignment between rewarding performance and holding management accountable for decisions that impact stockholders.

Engagement

Ensure Board engagement in key compensation decisions
At every Board meeting, the Chair of the Compensation Committee reports to the full Board the key items discussed and any actions taken at each Compensation Committee meeting.
All independent Directors are engaged in setting the CEO’s annual individual performance goals and reviewing the performance of the CEO each year.
The Compensation Committee reviews all decisions about CEO compensation with the independent Directors for ratification by the independent Directors.

Financial Performance Measures, Adjustments and Exercise of Discretion

Adjusted EPS is a primary metric that analysts use to evaluate the Company’s financial performance because it is an indicator of the earnings from ongoing business activities. EPS expectations are communicated to investors at the beginning of the year, and EPS is a key component of the Company’s value proposition. The Compensation Committee believes that adjusted EPS is the appropriate metric to align the interests of our executives with the Company’s strategy and with long-term value creation. Typical adjustments include the impact of items considered outside of normal operations or not anticipated in the business plan when the financial goals were established.

The Compensation Committee’s practice is to consider EPS and other financial measures on an adjusted basis as a starting point to its analysis. The Compensation Committee carefully considers calculated payouts under the annual and long-term incentive award programs to determine if the compensation result is aligned with operating and financial performance, the Board’s expectations and long-term stockholder value. If the Compensation Committee determines that the results are not aligned, then the Compensation Committee retains and, where appropriate, exercises discretion to adjust the payouts.

Peer Groups and Establishing Market-Based Compensation Levels

We consider two different peer groups as part of our compensation program.

Peer Group for 2017
Compensation Decisions

Used to assess and determine
the total direct compensation for our
executives

Includes more companies than
the peer group we use for
relative TSR metric since we
compete with a broader range of
large utilities for top talent

     
We target the total direct compensation for our executives at market median of a peer group of publicly-traded utility companies.
Pay Governance develops and presents to the Compensation Committee competitive market-based compensation levels for each of the executive officers. The market-based compensation levels are developed from the Willis Towers Watson Energy Services Survey (Survey) focusing on regulated utilities with revenues above $6 billion.
We are one of the largest utility holding companies in the United States based on revenues and market capitalization, and our largest business units are some of the largest in the industry as well. For that reason, Pay Governance uses survey data that is aligned with the scope of our business.
The compensation peer group stayed relatively the same from 2016 to 2017. Three new companies participated in the Survey, met the revenue guideline and were added to the group (GE Energy, National Grid and ONEOK, Inc.). Four companies that were in the peer group in 2016 were eliminated in 2017 because they did not meet the revenue guideline or did not participate in the updated Survey (Berkshire Hathaway Energy Company, Consolidated Edison, Inc., Monroe Energy LLC and NiSource Inc.).

Peer Group for Relative
TSR Metric for 2017-2019
Performance Period

Used to measure our relative TSR
performance, which is one of the
performance measures for the
long-term incentive award

 
In selecting the peer group used to measure relative TSR performance for the long-term incentive award, we identify companies that are believed to be most similar to Southern Company in both business model and investors.
Several companies in the relative TSR peer group do not meet the size requirement to be included in the compensation peer group (+$6 billion in revenues), and one company did not participate in the Survey from which the data for the compensation peer group is derived.

There is significant overlap between the peer group used for market-based compensation decisions and for measuring relative TSR performance.

Annual Incentive Compensation (At Risk)

2017 Performance Pay Program

PPP is a broad-based annual cash incentive award program designed to reward annual financial and operational performance.
For the executive officers, the program also rewards individual performance designed to drive long-term strategy by encouraging short-term (annual) behaviors that the Compensation Committee believes will create long-term stockholder value.
The target award amount is determined as a percentage of base salary, with the percentage varying by pay grade.
Payouts can range from 0% to 200% of target, based on actual level of goal achievement.

Establishing the Performance Goals and Weighting
The Compensation Committee sets goals and goal weighting for all participants at the beginning of each year.
The Compensation Committee establishes the financial goals of EPS and net income based on the Company’s financial plan and value proposition, focusing on providing regular, predictable and sustainable EPS and dividend growth and strong returns on capital. Each year, the financial plan is revised to reflect the current economic and regulatory environment and expectations for investment opportunities. The Compensation Committee establishes threshold, target and stretch targets for the Company following review of the financial plan scenarios, industry comparisons and growth expectations from the prior year.
In 2017, the EPS goal target was increased by 5% from 2016. The net income targets for the operating subsidiaries were similarly increased in 2017.
The Compensation Committee establishes operational goals that are primarily based on industry benchmarks, with an objective of delivering top quartile results compared to industry peers. For goals that do not have a comparable industry benchmark, the Compensation Committee sets stretch targets to motivate continuous improvement.
As part of its goal-setting process, the Compensation Committee reviews previous goals and performance along with input from the Finance Committee on financial goals (EPS and net income) and the Operations, Environmental and Safety Committee on operational goals to appropriately align the target and maximum goals with expected Company performance.
In addition, no payout can be made if events occur that impact the Company’s financial ability to fund the common stock dividend.

2017 Financial Performance

Financial Goals and Achievement for 2017 PPP

We exceeded the financial goals for the year set by the Compensation Committee under our 2017 PPP.

Financial Goals    Threshold    Target    Maximum    Result    Calculated
Achievement %
EPS*    $ 2.82   $ 2.96   $ 3.10  $ 3.02 170%

GAS Net Income* (millions) $ 400 $ 430 $ 450 $ 445 175%
*

In determining EPS and net income for compensation goal achievement purposes, the Compensation Committee excluded the impact of acquisition, disposition and integration costs, earnings from the Wholesale Gas Services business, charges for estimated losses related to the Kemper IGCC, additional equity return related to the Kemper IGCC, charges for a write-down of Gulf Power’s ownership of Plant Scherer Unit 3 and the net tax benefit as a result of federal tax reform. The Southern Company Gas net income result, which is included in the corporate net income result, also excludes the impact of a change in Illinois state tax law.

The corporate net income business unit financial goal payout is determined by the equity-weighted average payout of the Alabama Power, Georgia Power, Gulf Power, Mississippi Power, Southern Power and Southern Company Gas net income goals. For 2017, the calculated achievement of the corporate net income financial goal was 174%.

Individual Performance Results for 2017 PPP

In 2017, there were many significant accomplishments and advances for the Company led by our team of executive officers and, in particular, the CEO. Individual performance for executive officers was well differentiated based on a review of actual achievement against individual goals established for the year. The following areas were considered for assessing individual performance:

Provided leadership to meet or exceed financial targets on an adjusted basis and operational targets resulting in consistently paid stockholder dividends

Customer satisfaction ratings relative to peers and internal customer satisfaction metrics

Strong response to national storms including staff on the ground for months in Puerto Rico

Significant support for Plant Vogtle Units 3 and 4 after the site contractor announced bankruptcy, with solid progress made at the site

Achieved constructive regulatory outcomes in many jurisdictions

Strategically evaluated the portfolio to support long-term stockholder returns, including the planned sale of Elizabethtown Gas

Completed $6.9 billion of long-term financings and refinanced over $8.0 billion in revolving credit facilities

Continued to expand solar, wind and gas platforms

Expanded and took a significant leadership role in storm response, tax reform and other energy, economic and security advisory roles

Continued to advance the workforce and Company culture through focus on safety, compensation and benefits, diversity and inclusion, succession planning and development for all employees

Further improved stockholder relationships through significant outreach

Suspension of start-up activities and write-off of the gasifier portion of the Kemper IGCC

Continued promoting and driving energy innovation through launching Smart Neighborhoods in both Alabama and Georgia, engaging in focused research and development efforts to drive continuous improvement across the business portfolio, actively engaging nationally on innovation efforts and launching the “Alliance for Transportation Electrification” with Energy Impact Partners

Review by Compensation Committee and Final Payout Determinations

Payout Review by Compensation Committee for 2017 PPP

The Compensation Committee follows a number of steps in determining the final PPP payouts to our executive officers.

The Compensation Committee is updated on financial and operational progress against goals at each of its regular meetings throughout the year, including the impact of each EPS adjustment that formed part of our publicly disclosed earnings releases during the year. However, no decisions are made with respect to payouts for the Company’s executive officers until after the end of the year.

The CEO, assisted by the Chief Human Resources Officer and her staff, reviews the individual performance results for the executive officers and makes recommendations to the Compensation Committee. With respect to executive officers other than the CEO, the Compensation Committee also considers the recommendation of the CEO as to the application of its discretion.

The Compensation Committee, after input from the independent Directors, determines the individual performance results for the CEO.

The Compensation Committee determines whether to exercise discretion in determining the final payouts.

Payout decisions made by the Compensation Committee with respect to the CEO are discussed with and ratified by the independent Directors.

2017 Actual PPP Payouts

Based on the feedback from stockholder engagement, thoughtful consideration by the Compensation Committee and consultation with the independent compensation consultant, the Compensation Committee applied discretion to reduce the 2017 PPP payout to the CEO and certain other members of senior management. The Compensation Committee reduced the CEO’s calculated PPP payout by 55% or $1.61 million. This reduction was the equivalent of paying on earnings calculated under GAAP for the CEO’s award.

Long-Term Equity Incentive Compensation (At Risk)

2017 Long-Term Equity Incentive Grants

Long-term performance-based awards are intended to promote long-term success and increase stockholder value by directly tying a substantial portion of the NEOs’ total compensation to the interests of stockholders.
70% of the long-term equity incentive award is in performance share units that are earned solely based on achievement of pre-established performance goals over a three-year performance period from 2017 to 2019. Payouts can range from 0% to 200% of target, based on actual level goal achievement.
30% of the long-term equity incentive award is in PRSUs that are earned only if a pre-established performance goal is met. If the goal is not met, all PRSUs are forfeited. If the goal is met, the PRSUs vest one-third per year over a three-year period.
If earned, awards are paid in common stock. Accrued DEUs are received only if the underlying award is earned.

Changes to the Long-Term Equity Incentive Program for 2017

Our long-term equity incentive compensation program has changed over time as the Compensation Committee strives to establish programs that promote the long-term success of the Company as well as increase stockholder value while remaining market competitive to attract, engage and retain employees and reflect best compensation practices. In addition to working closely with Pay Governance, the Human Resources staff and the CEO to establish compensation programs, the Compensation Committee takes stockholder feedback into account when evaluating compensation programs.

In 2017, the Compensation Committee added PRSUs to the long-term equity incentive program at 30% of the total target value and continued with PSP awards at 70% of target value. The Compensation Committee believes that allocating a portion of the long-term equity incentive program to PRSUs with a one-year performance goal continues to provide alignment with stock price performance and enhance retention.

2017-2019 Performance Share Program

Establishing the Performance Goals

The PSP award includes financial and market-based performance goals over the three-year performance period from 2017 to 2019 and is further subject to a credit quality threshold requirement.

Goal    What it Measures    Why it’s Important

Relative TSR

TSR relative to a utility peer group of companies that are believed to be most similar to the Company in both business model and investors. It measures investment gains arising from stock price appreciation and dividends received from that investment. The peer group is described on page 51 and is subject to change based on merger and acquisition activity.

Aligns pay with investor returns relative to peers

Cumulative EPS

Cumulative EPS over the three-year performance period

Aligns pay with sustainable earnings and dividend growth

Consolidated ROE

Consolidated Southern Company ROE of the traditional electric operating companies, Southern Company Gas and Southern Power

Aligns pay with Southern Company’s ability to maximize return on capital invested

Beginning in 2017, the ROE goal is measured by the consolidated result for Southern Company rather than the equity-weighted ROE metric used in prior years. The ROE goal was changed due to the integration of Southern Company Gas, following the completion of the merger of Southern Company and Southern Company Gas in July 2016.

The financial goals are also subject to a credit quality threshold requirement that encourages the maintenance of adequate credit ratings to provide an attractive return to investors. If the primary credit rating falls below investment grade at the end of the three-year performance period, the payout for the EPS and ROE goals will be reduced to zero.

For each of the performance measures, a threshold, target and maximum goal was set at the beginning of 2017.

   Relative
TSR Performance
   Cumulative
EPS Performance
   Consolidated
ROE Performance
   Payout
Maximum 90th percentile or higher              $ 9.85 13.0% 200%
Target 50th percentile $ 9.33 11.0% 100%
Threshold 10th percentile $ 8.81 9.5% 0%

2017 Performance Restricted Stock Units

Establishing the Performance Goal

The PRSU award includes a financial performance goal that must be met after the first year for any PRSUs to vest during the three-year period.

The Compensation Committee carefully considered the appropriate financial performance goal for the PRSU program and ultimately decided to tie the vesting of the PRSUs to the Company’s commitment to ensuring our ability to pay regular dividends.

PRSUs are earned only if Southern Company’s cash from operations in 2017 exceeds $2.1 billion, the amount of dividends paid in 2016. If earned, the PRSUs vest one-third each year over a three-year period.

Compensation Discussion and Analysis

The equity-weighted ROE goal measured the returns of our traditional electric operating companies as well as the percentage of the capital structure that is financed with equity. The target is aligned with top quartile performance, and the maximum represents industry-leading performance, compared to electric operating company peers. The aggregate payout reflects maximum performance by Alabama Power and Georgia Power, below target performance for Gulf Power and zero payout contribution by Mississippi Power. The following table describes the results for each of the traditional electric operating companies.

Payout Review by Compensation Committee for 2015-2017 PSP

The Compensation Committee follows a number of steps in determining the final payouts.

The Compensation Committee is updated on financial and relative TSR progress against goals at each of its regular meetings throughout the three-year performance period, including the impact of each EPS adjustment that formed part of our publicly disclosed earnings releases during the period. However, no decisions are made with respect to payouts for our executive officers until after the end of the period.
The Compensation Committee determines whether to exercise discretion in determining the final payouts.
Payout decisions made by the Compensation Committee with respect to the CEO are discussed with and ratified by the independent Directors.

Based on the feedback from stockholder engagement, thoughtful consideration by the Compensation Committee and consultation with the independent compensation consultant, the Compensation Committee applied discretion to reduce the 2015-2017 PSP payout to the CEO and certain other members of senior management. The Compensation Committee reduced the CEO’s calculated PSP payout by 35% or $3.06 million. This reduction was the equivalent of paying on earnings calculated under GAAP for the CEO’s award.

Benefits

Retirement Benefits (except for Mr. Evans)

Employee Savings Plan: Substantially all employees are eligible to participate in the Employee Savings Plan (ESP), our 401(k) plan. The NEOs are also eligible to participate in the Supplemental Benefit Plan (SBP), which is a nonqualified deferred compensation plan where we can make contributions that are prohibited to be made under the ESP due to limits prescribed for 401(k) plans under the Internal Revenue Code of 1986, as amended (tax code).
Pension Benefits: Substantially all employees participate in a funded Pension Plan. Normal retirement benefits become payable when participants attain age 65. These benefits vest after the employee completes five years of vesting service. The Company also provides unfunded benefits to certain employees, including the NEOs, under two nonqualified plans: the Supplemental Benefit Plan (Pension-Related) (SBP-P) and the Supplemental Executive Retirement Plan (SERP). The SBP-P and the SERP provide additional benefits the Pension Plan cannot pay due to limits applicable to the Pension Plan.
Deferred Compensation Benefits: We offer a Deferred Compensation Plan (DCP), which is an unfunded plan that permits participants to defer income as well as certain federal, state and local taxes until a specified date or their retirement, disability, death or other separation from service.

Retirement Benefits for Mr. Evans

Mr. Evans continued to participate in the Southern Company Gas retirement plans that continued to operate in 2017 on the same basis as other Southern Company Gas employees, including:

AGL Resources Inc. Retirement Savings Plus Plan (RSP), a 401(k) plan;
AGL Resources Inc. Nonqualified Savings Plan (AGL NSP), a nonqualified defined contribution retirement plan;
AGL Resources Inc. Retirement Plan (AGL Pension Plan), a tax-qualified defined benefit pension plan; and
AGL Resources Inc. Excess Benefit Plan (AGL Excess Benefit Plan), a nonqualified defined benefit retirement plan.

Effective January 1, 2018, Mr. Evans began participating in the same Southern Company retirement and benefit plans as the other NEOs.

Change-in-Control Protections

We believe that change-in-control protections allow management to focus on potential transactions that are in the best interest of our stockholders.
Change-in-control protections include severance pay and, in some situations, vesting or payment of incentive awards.
We provide certain severance payments if there is a change in control of the Company and a termination of the executive’s employment (either involuntary termination not for cause or voluntary termination for good reason), often called a “double trigger”.
Severance payment for the CEO is three times salary plus target PPP opportunity. For the other NEOs, severance is two times salary plus target PPP opportunity. No excise tax gross-up would be provided.

Perquisites

We provide limited perquisites to our executive officers, consistent with the Company’s goal of providing market-based compensation and benefits.
No tax assistance is provided on perquisites to executive officers of the Company, except on certain relocation-related benefits that are generally available to all employees.

Other Compensation and Governance Inputs, Policies and Practices

  Role of the Compensation Committee
 ■ 
   
 
The Compensation Committee is responsible for overseeing the development and administration of our compensation and benefits policies and programs as well as the review and approval of all aspects of our executive compensation programs.
The Compensation Committee is supported in its work by the Chief Human Resources Officer, her staff, the Finance Committee (financial goals), the Operations, Environmental and Safety Committee (operational goals) and the Compensation Committee’s independent compensation consultant.
 ■   
  Role of the CEO
 ■ 
   
 
The CEO makes recommendations to the Compensation Committee regarding other executive officers with respect to (1) base salary adjustments, (2) PPP targets and individual performance achievement payouts and (3) long-term incentive compensation program targets. These recommendations are based upon market data provided by the independent compensation consultant, the CEO’s assessment of each executive officer’s performance, the performance of the individual’s respective business or function and employee retention considerations.
The Compensation Committee considers the CEO’s recommendations in approving the compensation for the other executive officers. However, the Compensation Committee makes the final decisions with respect to compensation decisions for the executive officers.
The CEO does not play any role with respect to decisions impacting his own compensation.
 
 
 ■ 
 
Role of the Independent Compensation Consultant
 ■   
   
 
The Compensation Committee has retained Pay Governance as its independent executive compensation consultant. Pay Governance reports directly to the Compensation Committee. A representative of Pay Governance attends meetings of the Compensation Committee, as requested, and communicates with the Compensation Committee Chair between meetings.
Pay Governance provides various executive compensation services to the Compensation Committee pursuant to a written consulting agreement with the Compensation Committee. Generally, these services include advising the Compensation Committee on the principal aspects of our executive compensation program and evolving industry practices and providing market information and analysis regarding the competitiveness of our program design and our award values in relation to the executive’s performance.
In 2017, Pay Governance provided an annual competitive evaluation of total compensation for the NEOs, as well as overall compensation program share usage, dilution and fair value expense. Additionally, the Compensation Committee relies on Pay Governance to provide information and advice on executive compensation and related corporate governance trends throughout the year. Pay Governance provided no services to Company management during 2017.
The Compensation Committee retains authority to hire Pay Governance directly, approve its compensation, determine the nature and scope of its services, evaluate its performance and terminate its engagement. The Compensation Committee has assessed the independence of Pay Governance pursuant to the listing standards of the NYSE and SEC rules and concluded that Pay Governance is independent and that no conflict of interest exists that would prevent Pay Governance from serving as an independent consultant to the Compensation Committee.

Compensation Discussion and Analysis

Prohibition on Hedging and Pledging of Common Stock

Our insider trading policy provides that employees, officers and Directors will not trade Company options on the options market and will not engage in short sales. It also includes a “no pledging” provision that prohibits pledging of our stock for all Southern Company executive officers and Directors.

Stock Ownership Requirements

We believe ownership requirements align the interest of officers and stockholders by promoting a long-term focus and long-term share ownership. All of the NEOs are subject to stock ownership requirements, expressed as a multiple of base salary. Under our stock ownership guidelines, the ownership requirement is reduced by one-half at age 60. All of the NEOs are meeting their applicable ownership requirements.

   Multiple of Salary without
Counting Stock Options
   Multiple of Salary Counting
Portion of Vested Stock Options
CEO 5 Times 10 Times
Other NEOs 3 Times 6 Times

Ownership arrangements counted toward the requirements include shares owned outright, those held in Company-sponsored plans and common stock accounts in the DCP and the SBP. A portion of vested stock options may be counted, but then the ownership requirement is doubled.

Newly-elected and newly-promoted officers have approximately six years from the date of their election or promotion to meet the applicable ownership requirement. We measure compliance with the stock ownership requirements as of September 30 each year.

Clawback of Awards

Our Omnibus Incentive Compensation Plan (Omnibus Plan) provides that if we are required to prepare an accounting restatement due to material noncompliance as a result of misconduct, and an executive officer of the Company knowingly or grossly negligently engaged in or failed to prevent the misconduct or is subject to automatic forfeiture under the Sarbanes-Oxley Act of 2002, the executive officer must repay us the amount of any payment in settlement of awards earned or accrued during the 12-month period following the first public issuance or filing that was restated.

Impact of Section 162(m) of the Tax Code on Compensation

Historically, Section 162(m) of the tax code limited the tax deductibility of the compensation of certain executive officers that exceeded $1 million per year unless the compensation was paid under a performance-based plan that has been approved by stockholders. Our compensation program has been designed with the intention that compensation paid in various forms may be eligible to qualify for deductibility under Section 162(m) of the tax code, but there have been and may be other exceptions for administrative or other reasons, and the Compensation Committee retains the discretion to award compensation that may not be tax deductible. Due to the elimination of the performance-based compensation exception under Section 162(m) of the tax code as a result of the recent enactment of the Tax Cuts and Jobs Act of 2017, it is likely that compensation paid after 2017 will no longer satisfy the requirements for tax deductibility under Section 162(m). Nevertheless, the Compensation Committee continues to believe that a significant portion of our executive officers’ compensation should be tied to performance measures.

Compensation Committee Interlocks and Insider Participation

The Compensation Committee is made up of independent Directors of the Company who have never served as executive officers of the Company. During 2017, none of the Company’s executive officers served on the Board of Directors of any entities whose executive officers serve on the Compensation Committee.

In order to show the effect that the year-over-year change in pension value had on total compensation, as determined under applicable SEC rules, we have included an additional column to show total compensation without the change in pension value. The amounts reported in this additional column differ substantially from the amounts reported in the Total column required by SEC rules and are not a substitute for that amount. The change in pension value is subject to many external variables, such as interest rates, that are not related to Company performance and does not represent compensation granted or received by the NEOs in the applicable year.

Column (a)

Compensation for Mr. Evans in 2016 reflects compensation paid on or after July 1, 2016 (subsequent to the completion of the merger of Southern Company Gas and Southern Company) through December 31, 2016.

Column (d)

This column does not reflect the value of stock awards that were actually earned or received in 2017. Rather, as required by applicable rules of the SEC, this column reports the aggregate grant date fair value of performance shares and PRSUs granted in 2017.

The value reported for the performance shares is based on the probable outcome of the performance conditions as of the grant date, using a Monte Carlo simulation model (50% of grant value) and the closing price of common stock on the grant date (50% of grant value). No amounts will be earned until the end of the three-year performance period on December 31, 2019. The value then can be earned based on performance ranging from 0% to 200%, as established by the Compensation Committee.

investor.southerncompany.com     67


Table of Contents

Executive Compensation Tables

The aggregate grant date fair value of the performance shares granted in 2017 assuming that the highest level of performance is achieved is as follows: Fanning — $12,284,940; Beattie — $2,925,944; Bowers — $3,328,312; Crosswhite — $2,983,735; and Evans — $3,359,969.

The amounts in column (d) also reflect the grant date fair value of PRSUs granted to all of the NEOs in 2017 as described in the CD&A. The aggregate grant date fair value of the PRSUs granted in 2017 and reported in column (d) is as follows: Fanning — $2,632,482; Beattie — $627,014; Bowers — $713,247; Crosswhite — $639,368; and Evans — $719,990.

See Note 8 to the financial statements included in the 2017 annual report for a discussion of the assumptions used in calculating these amounts.

Column (e)

The amounts in this column reflect actual payouts under the annual PPP. The amount reported for 2017 is for the one-year performance period that ended on December 31, 2017.

Column (f)

This column reports the aggregate change in the actuarial present value of each NEO’s accumulated benefit under the applicable Pension Plan and supplemental pension plans (collectively, Pension Benefits) as of December 31 of the applicable year.

The Pension Benefits as of each measurement date are based on the NEO’s age, pay and service accruals and the plan provisions applicable as of the measurement date. The actuarial present values as of each measurement date reflect the assumptions the Company selected for cost purposes as of that measurement date; however, the NEOs were assumed to remain employed at any Company subsidiary until their benefits commence at the pension plans’ stated normal retirement date, generally age 65.

Pension values may fluctuate significantly from year to year depending on a number of factors, including age, years of service, annual earnings and the assumptions used to determine the present value, such as the discount rate. For 2017, the discount rate assumption used to determine the actuarial present value of accumulated pension benefits, as required by SEC rules, was lower than in 2016. For Mr. Fanning, this lower discount rate assumption was one of the primary reasons for the increase in pension value. The other key reasons were an additional year of service and the increase in annual pensionable earnings from 2016 to 2017.

This column also reports any above-market earnings on deferred compensation under the DCP. However, there were no above-market earnings on deferred compensation in the years reported.

The values reported in this column are calculated pursuant to SEC requirements and are based on assumptions used in preparing the Company’s audited financial statements for the applicable fiscal years. The plans utilize a different method of calculating actuarial present value for the purpose of determining a lump sum payment, if any. The change in pension value from year to year as reported in the table is subject to market volatility and may not represent the value that an NEO will actually accrue or receive under the plans during any given year.

Perquisites includes financial planning, personal use of corporate aircraft and other miscellaneous perquisites.

Financial planning is provided for most officers of the Company, including all of the NEOs. The Company provides an annual subsidy of up to $8,200 to be used for financial planning, tax preparation fees and estate planning. In the initial year, the allowed amount is $13,200. Mr. Evans was covered by a separate policy for Southern Company Gas with an annual subsidy of up to $18,000.
The Southern Company system has aircraft that are used to facilitate business travel. All flights on these aircraft must have a business purpose, except limited personal use that is associated with business travel is permitted. The amount reported for such personal use is the incremental cost of providing the benefit, primarily fuel costs. Also, if seating is available, the Company permits a spouse or other family member to accompany an employee on a flight. However, because in such cases the aircraft is being used for a business purpose, there is no incremental cost associated with the family travel, and no amounts are included for such travel. Any additional expenses incurred that are related to family travel are included.
The Compensation Committee recognizes that permitting limited personal use of system aircraft for the CEO allows the CEO to continue to perform his duties in a safe, secure environment and promotes safe and effective use of his time. The amount included for Mr. Fanning includes $32,720 in approved personal use of corporate aircraft.
The amount included for Mr. Bowers includes $4,927 for limited personal use of corporate aircraft associated with business travel.
The personal safety and security of employees at home, at work and while traveling is of utmost importance to us. The amount reported for Mr. Evans includes $37,315 related to personal security expenses. Given Mr. Evans’ profile and high visibility, we believe that the costs of his security program are appropriate and a necessary business expense and that we can benefit from the added security measures for him. Costs reported reflect the initial procurement, installation and set-up of security measures during 2017.
Other miscellaneous perquisites include the full cost to the Company of providing the following items: personal use of Company-provided tickets for sporting and other entertainment events, spousal expenses related to business travel and gifts distributed to and activities provided to attendees at Company-sponsored events.

Columns (c), (d) and (e)

These columns reflect the annual PPP opportunity for the NEOs. The information shown as “Threshold,” “Target” and “Maximum” reflects the range of potential payouts established by the Compensation Committee. The actual amounts earned for 2017 are included in column (e) of the Summary Compensation Table.

Columns (f), (g) and (h)

These columns reflect the long-term PSP performance shares and PRSUs granted to the NEOs in 2017. The information shown as “Threshold,” “Target” and “Maximum” reflects the range of potential shares that can be earned as established by the Compensation Committee for the performance shares, while the information shown as “Target” for the PRSUs reflects the number of potential shares that can be earned if the performance condition is met. Earned performance shares and accrued DEUs will be paid out in common stock following the end of the 2017–2019 performance period, based on the extent to which the performance goals are achieved. Any shares not earned are forfeited. PRSUs vest 1/3 each year only if the performance goal is met for 2017. If the performance goal is met, PRSUs are paid out in common stock after vesting; accrued DEUs are received only if the underlying award is earned. If the performance goal is not met, then all PRSUs are forfeited.

Column (i)

This column reflects the aggregate grant date fair value of the PSP performance shares and PRSUs granted in 2017. 50% of the value of the performance shares is based on the probable outcome of the performance conditions as of the grant date using a Monte Carlo simulation model ($49.43), while the other 50% is based on the closing price of common stock on the grant date ($49.22). The value of the PRSUs is based on the closing price of common stock on the grant date ($49.22). The assumptions used in calculating these amounts are discussed in Note 8 to the financial statements included in the 2017 annual report.

Executive Compensation Tables

Columns (b), (c) and (d)

Stock options have not been granted since 2014. Stock options vest one-third per year on the anniversary of the grant date. Options granted from 2009 through 2014 with expiration dates from 2019 through 2024 were fully vested as of December 31, 2017.

Options also fully vest upon death, total disability or retirement and expire three years following death or total disability or five years following retirement, or on the original expiration date if earlier.

Columns (e) and (f)

These columns reflect the number of RSUs held by Mr. Evans as of December 31, 2017. In 2016, Mr. Evans held outstanding Southern Company Gas performance stock units (Gas PSUs). The Gas PSUs were assumed and converted into Southern Company RSUs pursuant to a ratio set forth in the merger agreement relating to the acquisition of Southern Company Gas. Dividends do not accrue on the RSUs, which vest according to the original schedule for the Gas PSUs. The outstanding RSUs reflected in the table vest on December 31, 2018.

The value in column (f) is based on the common stock closing price on December 29, 2017 ($48.09).

Columns (g) and (h)

These columns reflect the full number and value of PRSUs granted to the NEOs that vest 1/3 each year for a three-year period subject to the achievement of a one-year financial performance goal (Southern Company’s 2017 cash from operations exceeds the amount paid in dividends in 2016) and associated DEUs on the PRSUs. DEUs only pay out if the underlying shares vest. The Compensation Committee certified the achievement of this goal on February 12, 2018, and the first 1/3 vested upon that certification. The remaining 2/3 will vest equally on the second and third anniversaries of the grant date.

In accordance with SEC rules, column (g) also reflects the target number of performance shares granted under the PSP that can be earned at the end of each three-year performance period (January 1, 2016 through December 31, 2018 and January 1, 2017 through December 31, 2019). The number of shares reflected in column (g) also reflects the DEUs on the target number of performance shares. DEUs are credited over the performance period but are only received at the end of the performance period if the underlying performance shares are earned.

The performance shares granted for the January 1, 2015 through December 31, 2017 performance period that vested as of December 31, 2017 are reported in the Option Exercises and Stock Vested in 2017 table.

For Mr. Evans, column (g) also reflects a grant of performance share units in September 2016. A portion vests on each of the first three anniversaries of July 1, 2016, the completion of the merger of Southern Company and Southern Company Gas. The remainder may be earned solely based on achievement of a cumulative net income goal for Southern Company Gas over a three-year performance period. The number of shares reflected in column (g) also reflects the DEUs based on the target number of performance share units.

The value in column (h) is derived by multiplying the number of shares in column (g) by the common stock closing price on December 29, 2017 ($48.09). The ultimate number of shares earned, if any, will be based on the actual performance results at the end of each respective performance period.

Below is a description of Pension Benefits for persons employed by the Southern Company system other than Southern Company Gas and PowerSecure.

Pension Plan

The Pension Plan is a tax-qualified, funded plan. It is the Company’s primary retirement plan. Substantially all Southern Company system employees participate in this plan after one year of service. Normal retirement benefits become payable when participants attain age 65 and complete five years of participation. The plan benefit equals the greater of amounts computed using a “1.7% offset formula” and a “1.25% formula,” as described below. Benefits are limited to a statutory maximum.

The 1.7% offset formula amount equals 1.7% of final average pay times years of participation less an offset related to Social Security benefits. The offset equals a service ratio times 50% of the anticipated Social Security benefits in excess of $4,200. The service ratio adjusts the offset for the portion of a full career that a participant has worked. The highest three rates of pay out of a participant’s last 10 calendar years of service are averaged to derive final average pay. The rates of pay considered for this formula are the base salary rates with no adjustments for voluntary deferrals after 2008. A statutory limit restricts the amount considered each year; the limit for 2017 was $270,000.

The 1.25% formula amount equals 1.25% of final average pay times years of participation. For this formula, the final average pay computation is the same as above, but annual performance-based compensation earned each year is added to the base salary rates.

Early retirement benefits become payable once plan participants have, during employment, attained age 50 and completed 10 years of participation. Participants who retire early from active service receive benefits equal to the amounts computed using the same formulas employed at normal retirement. However, a 0.3% reduction applies for each month (3.6% for each year) prior to normal retirement that participants elect to have their benefit payments commence. For example, 64% of the formula benefits are payable starting at age 55. As of December 31, 2017, all of the NEOs (other than Mr. Evans) were retirement-eligible.

74     Southern Company 2018 Proxy Statement


Table of Contents

Executive Compensation Tables

The Pension Plan’s benefit formulas produce amounts payable monthly over a participant’s post-retirement lifetime. At retirement, plan participants can choose to receive their benefits in one of seven alternative forms of payment. All forms pay benefits monthly over the lifetime of the retiree or the joint lifetimes of the retiree and a beneficiary. A reduction applies if a retiring participant chooses a payment form other than a single life annuity. The reduction makes the value of the benefits paid in the form chosen comparable to what it would have been if benefits were paid as a single life annuity over the retiree’s life.

Participants vest in the Pension Plan after completing five years of vesting service. As of December 31, 2017, all of the NEOs were vested in their Pension Plan benefits. Participants who terminate employment after vesting can elect to have their pension benefits commence at age 50 if they participated in the Pension Plan for 10 years. If such an election is made, the early retirement reductions that apply are actuarially determined factors and are larger than 0.3% per month.

Prior to January 1, 2017, if a participant died while actively employed and was either age 50 or vested in the Pension Plan as of date of death, benefits would have been paid to a beneficiary. For deaths occurring on or after January 1, 2017, a participant must be vested in the Pension Plan as of the date of death. After commencing, survivor benefits are payable monthly for the remainder of a survivor’s life.

If participants become totally disabled, periods that Social Security or employer-provided disability income benefits are paid will count as service for benefit calculation purposes. The crediting of this additional service ceases at the point a disabled participant elects to commence retirement payments. Outside of this extra service crediting, the normal Pension Plan provisions apply to disabled participants.

SBP-P

The SBP-P is an unfunded retirement plan that is not tax qualified. This plan provides highly-paid employees any benefits that the Pension Plan cannot pay due to statutory pay/benefit limits. The SBP-P’s vesting and early retirement provisions mirror those of the Pension Plan. Its disability provisions mirror those of the Pension Plan but cease upon a participant’s separation from service.

The amounts paid by the SBP-P are based on the additional monthly benefit that the Pension Plan would pay if the statutory limits and pay deferrals were ignored. When a SBP-P participant separates from service, vested monthly benefits provided by the benefit formulas are converted into a single sum value. It equals the present value of what would have been paid monthly for an actuarially determined average post-retirement lifetime. The discount rate used in the calculation is based on the 30-year U.S. Treasury yields for the September preceding the calendar year of separation, but not more than six percent.

Vested participants terminating prior to becoming eligible to retire will be paid their single sum value as of September 1 following the calendar year of separation. If the terminating participant is retirement-eligible, the single sum value will be paid in 10 annual installments starting shortly after separation. The unpaid balance of a retiree’s single sum will be credited with interest at the prime rate published in The Wall Street Journal. If the separating participant is a “key man” under Section 409A of the tax code, the first installment will be delayed for six months after the date of separation.

If a SBP-P participant dies while active after becoming vested in the Pension Plan, the beneficiary of the deceased participant will receive the single sum value in a single payment as soon as possible following death. The single sum value is calculated as if the participant had survived to age 50 and discounted back to the payment date (if earlier). Spouse beneficiaries receive 100% and non-spouse beneficiaries receive 50% of the single sum value.

SERP

The SERP is also an unfunded retirement plan that is not tax qualified. This plan provides highly-paid employees additional benefits that the Pension Plan and the SBP-P would pay if the 1.7% offset formula calculations reflected a portion of annual performance-based compensation. To derive the SERP benefits, a final average pay is determined reflecting participants’ base rates of pay and their annual performance-based compensation amounts, whether or not deferred, to the extent they exceed 15% of those base rates (ignoring statutory limits). This final average pay is used in the 1.7% offset formula to derive a gross benefit. The Pension Plan and the SBP-P benefits are subtracted from the gross benefit to calculate the SERP benefit. The SERP’s early retirement, survivor benefit and disability

investor.southerncompany.com     75


Table of Contents

Executive Compensation Tables

provisions mirror the SBP-P’s provisions. SERP benefits do not vest until participants become eligible to retire, so no benefits are paid if a participant terminates prior to becoming retirement-eligible. More information about vesting and payment of SERP benefits following a change in control is included under Potential Payments upon Termination or Change in Control. Effective January 1, 2016, participation in the SERP was closed to new hires and future promotions.

Supplemental Retirement Agreements (SRA)

The Company also provides supplemental retirement benefits to certain employees that were first employed by an affiliate of the Company in the middle of their careers. These SRAs provide for additional retirement benefits by giving credit for years of employment prior to employment with the Company or one of its affiliates. These agreements provide a benefit which recognizes the expertise brought to the Southern Company system, and they provide a strong retention incentive to remain with the Company, or one of its affiliates, for the vesting period and beyond. These supplemental retirement benefits are also unfunded and not tax-qualified.

The Company has an SRA with Mr. Crosswhite. Prior to his employment with the Southern Company system, Mr. Crosswhite provided legal services to Southern Company’s subsidiaries. His agreement provides an additional fifteen years of benefits. Mr. Crosswhite was vested in his benefits as of December 31, 2015.

Pension Benefit Assumptions

The following assumptions were used in the present value calculations for all pension benefits:

Discount rate — 3.82% Pension Plan and 3.50% supplemental plans as of December 31, 2017
Retirement date — Normal retirement age (65 for all NEOs)
Mortality after normal retirement — adjusted RP-2014 mortality tables with generational projections (MP-2017)
Mortality, withdrawal, disability and retirement rates prior to normal retirement — None
Form of payment for pension benefits
Male retirees: 25% single life annuity; 25% level income annuity; 25% joint and 50% survivor annuity; and 25% joint and 100% survivor annuity
Female retirees: 50% single life annuity; 30% level income annuity; 15% joint and 50% survivor annuity; and 5% joint and 100% survivor annuity
Spouse ages — Wives two years younger than their husbands
Annual performance-based compensation earned but unpaid as of the measurement date — 130% of target opportunity percentages times base rate of pay for year amount is earned
Installment determination — 3.75% discount rate for single sum calculation and 4.25% prime rate during installment payment period.

For all of the NEOs, the number of years of credited service is one year less than the number of years of employment.



Below is a description of pension benefits as of December 31, 2017 for persons employed by Southern Company Gas, including Mr. Evans.

AGL Pension Plan

The AGL Pension Plan is the pension plan for Southern Company Gas employees. The AGL Pension Plan is a tax-qualified, funded plan. Generally, all non-union employees who have a hire date on or before December 31, 2011 and all union employees who have a hire date on or before December 31, 2012 are eligible to participate in the AGL Pension Plan, upon completion of one year of service and attainment of age 21. Normal retirement benefits become payable when participants attain age 65. AGL Pension Plan benefits are determined by a career average pay

76     Southern Company 2018 Proxy Statement


Table of Contents

Executive Compensation Tables

formula. The benefit equals 1% of career average pay plus 0.5% of career average pay in excess of 50% of the Social Security Taxable Wage Base. Eligible compensation includes base pay, overtime and short-term incentives. Benefits are limited to a statutory maximum. A statutory limit restricts the amount considered each year; the limit for 2017 was $270,000.

Early retirement benefits become payable once plan participants have, during employment, attained age 55 and completed five years of service. Participants who retire early from active service receive reduced benefits. However, the reduced amount is subsidized so that the reduction from the normal retirement benefit is less severe than a full actuarial reduction. Employees who retire after age 62 with at least 25 years of service are eligible for an unreduced early retirement benefit. As of December 31, 2017, Mr. Evans was not retirement-eligible.

At retirement, plan participants can choose to receive their benefits from various forms of payment. Most forms pay benefits monthly over the lifetime of the retiree or the joint lifetimes of the retiree and a spouse. A reduction applies if a retiring participant chooses a payment form other than a single life annuity. The reduction makes the value of the benefits paid in the form chosen comparable to what it would have been if benefits were paid as a single life annuity over the retiree’s life. The AGL Pension Plan offers a single lump sum payment if the participant’s single lump sum amount is less than $10,000.

Participants vest in the AGL Pension Plan after completing five years of service. As of December 31, 2017, Mr. Evans is vested in his AGL Pension Plan benefit. If a participant dies while actively employed and vested in the AGL Pension Plan as of date of death, benefits will be paid to a spouse. After commencing, survivor benefits are payable monthly for the remainder of a survivor’s life depending on the form of payment selected.

If participants become totally disabled with 10 years of service, periods that Social Security or employer-provided disability income benefits are paid will count as service for benefit calculation purposes. The crediting of this additional service ceases at the time the participant qualifies for unreduced benefits. Outside of this extra service crediting, the normal AGL Pension Plan provisions apply to disabled participants.

AGL Excess Benefit Plan

The AGL Excess Benefit Plan is an unfunded retirement plan that is not tax-qualified. This plan provides highly-paid employees any benefits that the AGL Pension Plan cannot pay due to statutory pay/benefit limits. The AGL Excess Benefit Plan’s provisions mirror those of the AGL Pension Plan. Benefits under the AGL Excess Benefit Plan are paid in the same forms available under the AGL Pension Plan and are distributed at the later of separation from service or age 62.

Pension Benefit Assumptions

The following assumptions were used in the present value calculations for pension benefits related to pension benefits for Southern Company Gas employees:

Discount rate — 3.74% as of December 31, 2017
Retirement age — earliest unreduced for AGL Pension Plan and age 62 for AGL Excess Benefit Plan
Mortality after normal retirement — RP-2014 mortality tables backed up to 2006 by Scale MP-2014 and projected forward with MP-2017 (Amount weighted total employee and total annuitant)
Salary scale — none
Mortality, withdrawal, disability and retirement rates prior to normal retirement — none
Form of payment for pension benefits – life annuity

The amounts shown for Mr. Evans include contributions made and earnings under the AGL NSP.

The Company provides the DCP (excluding Southern Company Gas and PowerSecure employees), which is designed to permit participants to defer income as well as certain federal, state and local taxes until a specified date or their retirement or other separation from service. Up to 50% of base salary and up to 100% of performance-based non-equity compensation may be deferred at the election of eligible employees. All of the NEOs, except Mr. Evans, are eligible to participate in the DCP. Mr. Evans is a participant in the AGL NSP, described below.

DCP participants have two options for the deemed investments of the amounts deferred — the stock equivalent account and the prime equivalent account. Under the terms of the DCP, participants are permitted to transfer between investments at any time.

The amounts deferred in the stock equivalent account are treated as if invested at an equivalent rate of return to that of an actual investment in common stock, including the crediting of dividend equivalents as such are paid by Southern Company from time to time. It provides participants with an equivalent opportunity for the capital appreciation (or loss) and income of that of a Company stockholder. During 2017, the rate of return in the stock equivalent account was 2.32%.

Alternatively, participants may elect to have their deferred compensation deemed invested in the prime equivalent account, which is treated as if invested at a prime interest rate compounded monthly, as published in The Wall Street Journal as the base rate on corporate loans posted as of the last business day of each month by at least 75% of the United States’ largest banks. The interest rate earned on amounts deferred during 2017 in the prime equivalent account was 4.21%.

Under the AGL NSP, eligible employees, including Mr. Evans, are allowed to defer up to 75% of base salary and 100% of annual incentive pay as before-tax contributions. The timing restrictions for contribution deferral elections are intended to comply with Section 409A of the tax code, as well as other applicable tax code provisions. Under the AGL NSP, the amount of matching contributions is offset by the maximum matching contributions the participant could receive under the tax-qualified RSP. Southern Company Gas matches 65% of participant contributions, up to the first 8% of the participant’s covered compensation. Each participant in the AGL NSP has an account, which represents a bookkeeping entry reflecting contributions and earnings/losses on the actual performance of the participant’s notional investments. The notional investment options under the AGL NSP mirror the investment options offered under the RSP. Participants are 100% vested in their own contributions and vest in employer-matching contributions over a three-year period according to a vesting schedule. Mr. Evans has met the vesting requirements under the AGL NSP.

Distributions under the AGL NSP occur in the year following the year of termination of employment. Participants have the option of taking distributions, following termination of employment, in the following forms: a single lump sum cash payment; a lump sum cash payment of a portion of the participant’s account with the remainder distributed in up to 10 equal annual installments; or between one to 10 equal annual installments.

Column (b)

This column reports the actual amounts of compensation deferred under the DCP or AGL NSP, as applicable, by each NEO in 2017. The amount of salary deferred by the NEOs, if any, is included in the Salary column in the Summary Compensation Table. The amounts of performance-based compensation deferred in 2017 were the amounts that were earned as of December 31, 2016 but were not payable until the first quarter of 2017. These amounts are not reflected in the Summary Compensation Table because that table reports performance-based compensation that was earned in 2017 but not payable until early 2018. Amounts under the DCP may be distributed in a lump sum or in up to 10 annual installments at termination of employment or in a lump sum at a specified date, at the election of the participant.

Column (c)

This column reflects contributions under the SBP and, for Mr. Evans, the AGL NSP. Under the tax code, employer-matching contributions are prohibited under the ESP and the RSP on employee contributions above stated limits, and, if applicable, above legal limits set forth in the tax code.

Each of the SBP and the AGL NSP is a nonqualified deferred compensation plan under which contributions are made that are prohibited from being made in the ESP or the RSP. The contributions are treated as if invested in common stock and are payable in cash upon termination of employment in a lump sum or in up to 20 annual installments, at the election of the participant. The amounts reported in this column also were reported in the All Other Compensation column in the Summary Compensation Table.

Column (d)

This column reports earnings or losses on compensation the NEOs elected to defer and on employer contributions under the SBP.

Column (f)

This column includes amounts that were deferred under the DCP or the AGL NSP and contributions under the SBP or the AGL NSP in prior years. The following chart shows the amounts previously reported.

Potential Payments Upon Termination or Change in Control

This section describes and estimates payments that could be made to the NEOs serving as of December 31, 2017 under different termination and change-in-control events. The estimated payments would be made under the terms of Southern Company’s compensation and benefit program, the Southern Company Gas program or the change-in-control severance program.

All of the NEOs are participants in Southern Company’s change-in-control severance program for officers. The amount of potential payments is calculated as if the triggering events occurred as of December 31, 2017 and assumes that the price of common stock is the closing market price on December 29, 2017.

Description of Termination and Change-in-Control Events

The following charts list different types of termination and change-in-control events that can affect the treatment of payments under the compensation and benefit programs. No payments are made under the change-in-control severance program unless, within two years of the change in control, the NEO is involuntarily terminated or voluntarily terminates for good reason.

Traditional Termination Events

Retirement or Retirement-Eligible — Termination of NEO who is at least 50 years old and has at least 10 years of credited service.

Resignation — Voluntary termination of NEO who is not retirement-eligible.

Lay Off — Involuntary termination of NEO who is not retirement-eligible not for cause.

Involuntary Termination — Involuntary termination of NEO for cause. Cause includes individual performance below minimum performance standards and misconduct, such as violation of the Company’s Drug and Alcohol Policy.

Death or Disability — Termination of NEO due to death or disability.

Change-in-Control-Related Events

At the Company or the subsidiary company level:

Company Change in Control I — Consummation of an acquisition by another entity of 20% or more of common stock or, following consummation of a merger with another entity, the Company’s stockholders own 65% or less of the entity surviving the merger.

Company Change in Control II — Consummation of an acquisition by another entity of 35% or more of common stock or, following consummation of a merger with another entity, the Company’s stockholders own less than 50% of the Company surviving the merger.

Company Does not Survive Merger — Consummation of a merger or other event and the Company is not the surviving company or the common stock is no longer publicly traded.

Subsidiary Company Change in Control — Consummation of an acquisition by another entity, other than another subsidiary of the Company, of 50% or more of the stock of any of the Company’s subsidiaries, consummation of a merger with another entity and the Company’s subsidiary is not the surviving company, or the sale of substantially all the assets of any of the Company’s subsidiaries.

At the employee level:

Involuntary Change-in-Control Termination or Voluntary Change-in-Control Termination for Good Reason—Employment is terminated within two years of a change in control, other than for cause, or the employee voluntarily terminates for good reason. Good reason for voluntary termination within two years of a change in control generally is satisfied when there is a material reduction in salary, performance-based compensation opportunity or benefits, relocation of over 50 miles or a diminution in duties and responsibilities.

Potential Payments

This section describes and estimates payments that would become payable to the NEOs upon a termination or change in control as of December 31, 2017.

Pension Benefits

The amounts that would have become payable to the NEOs if the Traditional Termination Events occurred as of December 31, 2017 under the Pension Plan, the SBP-P, the SERP, the AGL Pension Plan and the AGL Excess Pension Plan are itemized in the following chart. The amounts shown under the Retirement and Resignation or Involuntary Termination columns are amounts that would have become payable to the NEOs that were retirement-eligible on December 31, 2017 and are the monthly Pension Plan benefits and the first of 10 annual installments from the SBP-P and the SERP.

Mr. Evans was not retirement-eligible on December 31, 2017. For Mr. Evans, the amounts shown under the Resignation or Involuntary Termination column are the amounts that would have become payable as a monthly annuity.

The amounts shown that are payable to a beneficiary in the event of the death of the NEO are the monthly amounts payable to a beneficiary under the Pension Plan and single sum value of benefits for a spouse beneficiary from the SBP-P and the SERP. If an executive designates a non-spouse beneficiary, then the amount payable is 50% of the amount shown. The amounts shown for Mr. Evans are the amounts that would have become payable to his spouse on a monthly basis under the AGL Pension Plan and the AGL Excess Benefit Plan.

The amounts in this chart are very different from the pension values shown in the Summary Compensation Table and the Pension Benefits table. Those tables show the present values of all the benefit amounts anticipated to be paid over the lifetimes of the NEOs and their beneficiaries. Those plans are described in the notes following the Pension Benefits table.

As described in the change-in-control chart, the only change in the form of payment, acceleration or enhancement of the pension benefits is that the single sum value of benefits earned up to the change-in-control date under the SBP-P, the SERP, the SRA and the AGL Excess Benefit Plan could be paid as a single payment rather than in 10 annual installments. Also, the SERP benefits vest for participants who are not retirement-eligible upon a change in control.

The pension benefit amounts in the tables above were calculated as of December 31, 2017 assuming payments would begin as soon as possible under the terms of the plans. Accordingly, appropriate early retirement reductions were applied. Any unpaid annual performance-based compensation was assumed to be paid at 1.30 times the target level. Pension Plan and AGL Pension Plan benefits were calculated assuming each NEO chose a single life annuity form of payment, because that results in the greatest monthly benefit. The single sum values were based on a 2.35% discount rate for the Pension Plan and a 3.74% discount rate for the AGL Pension Plan.

Annual Performance Pay Program

The amount payable in the event of a change in control is the greater of target or the three-year historical average payout at the applicable business unit. Because actual payouts for 2017 performance were above the target level for all of the NEOs, the amount that would have been payable was the three-year historical average payout at the applicable business unit. There is no enhancement or acceleration of payments upon a change in control under the Southern Company Gas PPP.

Stock Options, Performance Shares, PRSUs and RSUs (Equity Awards)

Equity Awards would be treated as described in the Termination and Change-in-Control charts above. If Southern Company consummates a merger and is not the surviving company, all Equity Awards vest and performance shares vest at target. However, there is no payment associated with Equity Awards in that situation unless the participants’ Equity Awards cannot be converted into surviving company awards. In that event, the value of outstanding Equity Awards would be paid to the NEOs. In addition, if there is an Involuntary Change-in-Control Termination or Voluntary Change-in-Control Termination for Good Reason, Equity Awards vest and performance shares vest at target.

For stock options, the value is the excess of the exercise price and the closing price of common stock on December 29, 2017. The value of performance shares, PRSUs and RSUs is calculated using the closing price of common stock on December 29, 2017.

The chart below shows the number of stock options for which vesting would be accelerated and the amount that would be payable if there were no conversion to the surviving company’s stock options. It also shows the number and value of performance share, PRSUs and RSUs that would be paid.

Executive Compensation Tables

DCP, SBP and AGL NSP

The aggregate balances reported in the Nonqualified Deferred Compensation table would be payable to the NEOs as described in the Traditional Termination and Change-in-Control-Related Events charts above. There is no enhancement or acceleration of payments under these plans associated with termination or change-in-control events, other than the lump-sum payment opportunity described in the above charts. The lump sums that would be payable are those that are reported in the Nonqualified Deferred Compensation table.

Healthcare Benefits

All of the NEOs except Mr. Evans are retirement-eligible. Healthcare benefits are provided to retirees, and there is no incremental payment associated with the termination or change-in-control events, except in the case of a change-in-control-related termination, as described in the Change-in-Control-Related Events chart. The estimated cost of providing healthcare insurance premiums for up to a maximum of three years is $34,360 for Mr. Evans.

Financial Planning Perquisite

An additional year of the financial planning perquisite, which is set at a maximum of $8,700 per year, will be provided after retirement for retirement-eligible NEOs.

There are no other perquisites provided to the NEOs under any of the traditional termination or change-incontrol-related events.

Severance Benefits

The NEOs are participants in a change-in-control severance plan. The plan provides severance benefits, including outplacement services, if within two years of a change in control they are involuntarily terminated not for cause or they voluntarily terminate for good reason. The severance benefits are not paid unless the NEO releases the employing company from any claims the NEO may have against the employing company.

The severance payment is three times the base salary and target payout under the annual PPP for Mr. Fanning and two times the base salary and target payout under the annual PPP for the other NEOs.
The estimated cost of providing the six months of outplacement services is $6,000 per NEO.
If any portion of the severance amount constitutes an “excess parachute payment” under Section 280G of the tax code and is therefore subject to an excise tax, the severance amount will be reduced unless the after-tax “unreduced amount” exceeds the after-tax “reduced amount.” Excise tax gross-ups will not be provided on change-in-control severance payments.

The table below estimates the severance payments that would be made to the NEOs if they were terminated as of December 31, 2017 in connection with a change in control.

Pay Ratio Disclosure

We calculated a 2017 pay ratio of 114 to 1. This ratio is a reasonable estimate calculated in a manner consistent with SEC rules based on our payroll and employment records as of December 31, 2017 and the methodology described below.

The Southern Company system has over 31,000 employees across 34 states. We determined our median employee based on an analysis of all employees as of December 31, 2017. We used total cash compensation as reported in Form W-2 for 2017 as our consistently applied compensation measure. We then applied a statistical sampling approach to identify employees who we expected were paid within a +/- 0.1% range above and below our estimated median total cash compensation value. From this group, we selected an employee who was reasonably representative of our median employee based on average employee tenure and age. We did not exclude any employees across the Southern Company system in identifying the median employee nor did we annualize compensation for any of our employees. After identifying the median employee, we calculated the median employee’s annual total compensation as follows:

The annual total compensation of the median employee, calculated in accordance with the Summary Compensation Table requirements, was $138,000. The median employee’s annual total compensation is comprised of approximately $86,000 in base salary, $15,000 in short-term incentive payout and $37,000 in change in pension value and ESP matching contributions.
The CEO’s annual total compensation, as reported in the Summary Compensation Table, was $15,702,228.

The SEC’s rules for identifying the median compensated employee and calculating the pay ratio based on that employee’s annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions and to make reasonable estimates and assumptions that reflect their employee populations and compensation practices. As a result, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies have different employee populations and compensation practices and may utilize different methodologies, exclusions, estimates and assumptions in calculating their pay ratios.

Say on Pay Proposal

Item 2 ►   Advisory Vote to Approve Executive Compensation (Say on Pay)

The Board recommends a vote FOR approval of executive compensation.

 
As described in the CD&A beginning on page 41, we believe our compensation program provides the appropriate mix of fixed and at-risk compensation. Our short- and long-term performance-based compensation program ties pay to Company performance, rewards achievement of financial and operational goals and relative TSR, encourages individual performance that is consistent with our long-term strategy, is aligned with stockholder interests and remains competitive with our industry peers.

We design our compensation program to attract, engage, competitively compensate and retain our employees. We target the total direct compensation for our executives at market median and place a very significant portion of that target compensation at risk, subject to achieving both short-term and long-term performance goals.

At our 2017 annual meeting, we received 62% support for our executive compensation program. While this reflected continued majority support of our program, we were disappointed in the decline in support compared to prior years and wanted to understand the cause.

We regularly communicate with our stockholders to better understand their viewpoints, gather input on our business strategy and execution and obtain feedback regarding other matters of investor interest. Over the past year, we engaged extensively with stockholders and listened to what they had to say about our executive compensation program. We reached out to stockholders representing more than 35% of our outstanding shares and had approximately 45 meetings by telephone or in person with stockholders representing more than 31% of our outstanding shares. The primary concern identified by stockholders that drove last year’s reduction in support was the exclusion of 2016 charges to earnings related to the Kemper IGCC in determining incentive compensation payouts.

Based on this feedback, thoughtful consideration by the Compensation Committee and consultation with the independent compensation consultant, the Compensation Committee applied discretion to reduce 2017 incentive payouts for the CEO and certain other members of senior management to ensure that 2017 pay is aligned with financial performance and stockholder interests. In aggregate, CEO incentive pay was reduced by $4.68 million, reflecting a 40% reduction as compared to the calculated award amounts. This reduction was the equivalent of paying on earnings calculated under GAAP for the CEO's incentive awards.

Stockholders are voting to approve, on an advisory basis, the following resolution:

“RESOLVED, that the stockholders approve the compensation of the named executive officers described in the Compensation Discussion and Analysis, the Summary Compensation Table and the other compensation tables and accompanying narrative in the proxy statement.”

Although it is non-binding on the Board, the Compensation Committee will review and consider the vote results when making future decisions about the executive compensation program.

At the 2017 annual meeting, stockholders indicated a preference for an annual Say on Pay vote. In light of the vote, the Board determined that we will continue to conduct the Say on Pay vote annually.

The Board recommends a vote FOR approval of executive compensation.

Audit Committee Matters

Audit Committee Report

The Audit Committee oversees the Company’s financial reporting process on behalf of the Board of Directors. Management has the primary responsibility for establishing and maintaining adequate internal controls over financial reporting, including disclosure controls and procedures, and for preparing the Company’s consolidated financial statements.

In fulfilling its oversight responsibilities, the Audit Committee reviewed and discussed the audited consolidated financial statements of the Company and its subsidiaries and management’s report on the Company’s internal control over financial reporting in the 2017 annual report with management. The Audit Committee also reviews the Company’s quarterly and annual reporting on Forms 10-Q and 10-K prior to filing with the SEC. The Audit Committee’s review process includes discussions of the quality, not just the acceptability, of the accounting principles, the reasonableness of significant judgments and estimates and the clarity of disclosures in the financial statements.

The independent registered public accounting firm is responsible for expressing opinions on the conformity of the consolidated financial statements with accounting principles generally accepted in the United States and the effectiveness of the Company’s internal control over financial reporting with the criteria established in “Internal Control — Integrated Framework (2013)” issued by the Committee of Sponsoring Organizations of the Treadway Commission.

The Audit Committee has discussed with the independent registered public accounting firm the matters that are required to be discussed by the Public Company Accounting Oversight Board (PCAOB) Auditing Standard No. 16, Communications with Audit Committees and SEC Rule 2-07 of Regulation S-X, Communications with Audit Committees. In addition, in accordance with the rules of the PCAOB, the Audit Committee has discussed with and has received the written disclosures and letter from the independent registered public accounting firm regarding its independence from management and the Company. The Audit Committee also has considered whether the independent registered public accounting firm’s provision of non-audit services to the Company is compatible with maintaining the firm’s independence.

The Audit Committee discussed their overall audit scopes and plans separately with the Company’s internal auditors and independent registered public accounting firm. The Audit Committee meets with the internal auditors and the independent registered public accounting firm, with and without management present, to discuss the results of their audits, evaluations by management and the independent registered public accounting firm of the Company’s internal control over financial reporting and the overall quality of the Company’s financial reporting. The Audit Committee also meets privately with the Company’s compliance officer. The Audit Committee held nine meetings during 2017.

In reliance on the reviews and discussions referred to above, the Audit Committee recommended to the Board of Directors (and the Board approved) that the audited consolidated financial statements be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 and filed with the SEC. The Audit Committee also reappointed Deloitte & Touche as the Company’s independent registered public accounting firm for 2018. Stockholders are being asked to ratify that selection at the 2018 annual meeting.

Policy on Audit and Non-Audit Services

The Audit Committee’s Policy on Engagement of the Independent Auditor for Audit and Non-Audit Services includes requirements for the Audit Committee to pre-approve services provided by the Company’s principal independent registered public accounting firm. All services included in the previous chart were pre-approved by the Audit Committee.

Under the policy, the independent registered public accounting firm delivers an annual engagement letter which provides a description of services anticipated to be rendered to the Company by the independent registered public accounting firm for the Audit Committee to approve. The Audit Committee’s approval of the independent registered public accounting firm’s annual engagement letter constitutes pre-approval of all services covered in the letter.
In addition, under the policy, the Audit Committee has pre-approved the engagement of the independent registered public accounting firm to provide services related to the issuance of comfort letters and consents required for securities sales by the Company and services related to consultation on routine accounting and tax matters.
The Audit Committee has delegated pre-approval authority to the Chair of the Audit Committee with respect to permissible services up to a limit of $50,000 per engagement. The Chair of the Audit Committee is required to report any pre-approval decisions at the next scheduled Audit Committee meeting.
Prohibited non-audit services are services prohibited by the SEC to be performed by the Company’s independent registered public accounting firm. These services include bookkeeping or other services related to the preparation of accounting records or financial statements of the Company, financial information systems design and implementation, appraisal or valuation services, fairness opinions or contribution-in-kind reports, actuarial services, internal audit outsourcing services, management functions or human resources, broker-dealer, investment advisor or investment banking services, legal services and expert services unrelated to the audit, and any other service that the PCAOB determines, by regulation, is impermissible. In addition, officers of the Company may not engage the independent registered public accounting firm to perform any personal services, such as personal financial planning or personal income tax services.

Stockholder Proposal

Item 4 ►   Amendment to Proxy Access By-Law

The Board recommends a vote AGAINST Item 4.

 
We have been advised that John Chevedden, holder of at least 100 shares of common stock, proposes to submit the following resolution at the annual meeting.

Proposal 4 - Enhanced Shareholder Proxy Access

RESOLVED: Stockholders ask the board of directors to amend its proxy access bylaw provisions and any associated documents, to include the following changes for the purpose of decreasing the average amount of Company common stock the average member of a nominating group would be required to hold for 3-years to satisfy the aggregate ownership requirements to form a nominating group and to increase the possible number of proxy access director candidates:

No limitation shall be placed on the number of stockholders that can aggregate their shares to achieve the 3% of common stock required to nominate directors under our Company’s proxy access provisions.

The number of shareholder-nominated candidates eligible to appear in proxy materials will be 25% of Directors.

Even if the 20 largest public pension funds were able to aggregate their shares, they would not meet the current 3% criteria for a continuous 3-years at most companies according to the Council of Institutional Investors. This proposal addresses the sadly ironic situation that our company now has with proxy access potentially for only the largest shareholders who are the least likely shareholders to make use of it.

For 20 shareholders to make use of our current proxy access – the average holding for such a group of 20 Southern Company shareholders would be $75 million each. Plus it might take an average current holding of $150 million each when any stock held for less than 3 continuous years is subtracted.

Please vote to improve management accountability to shareholders:
Enhanced Shareholder Proxy Access – Proposal 4

Board's Recommendation and Statement in Response
The Board recommends a vote AGAINST Item 4 for the following reasons:

The Board has carefully considered the proposal and recommends a vote AGAINST the proposal. In 2016, the Board recommended, and stockholders approved, a meaningful proxy access right for stockholders that is aligned with current best practices and gives stockholders a meaningful voice in the Director nomination and election process. The Board believes that our current proxy access By-Law continues to be in the best interests of all stockholders and that implementation of the changes requested by the proposal would disrupt the balance achieved in the current By-Law and take us out of step with the public companies that have adopted proxy access.

Since May 2016, our By-Laws have provided that any stockholder or group of up 20 stockholders that has maintained continuous qualifying ownership of at least 3% of our outstanding shares for at least three years can nominate and include in our proxy materials Director nominees constituting the greater of two nominees or 20% (rounded down) of the number of Directors in our proxy materials for the next annual meeting.
The Board’s decision to propose a proxy access amendment to our By-Laws at the 2016 annual meeting was the result of feedback from stockholder outreach throughout 2015 and 2016, consideration of evolving corporate governance trends and continuous review of our corporate governance practices. The proposed amendment was overwhelmingly approved by stockholders at the 2016 annual meeting, with support from over 95% of the shares voted.

Stockholder Proposal

The Board continues to believe that our proxy access framework strikes the appropriate balance between promoting stockholder nomination rights and protecting the interests of all our stockholders.
The proposal requests removal of the limitation on the number of stockholders that can aggregate their shares to meet the 3% ownership threshold and would place no limit on the size of the group. We believe the 20-stockholder aggregation limit in our proxy access By-Law is a reasonable limitation to control the administrative burden of confirming and monitoring share ownership within a nominating group and prevent the use of proxy access by a group that includes stockholders that do not have a substantial economic stake in the Company. In addition, a 20-stockholder limit is widely embraced by companies that have adopted proxy access. There are multiple combinations of 20 stockholders that collectively own 3% of the outstanding shares.
The proposal requests an increase in the number of permitted proxy access nominees to 25% of the Board. We believe that increasing the potential level of Board representation to 25% of the Board could have unintended effects, such as promoting the use of proxy access to lay the groundwork for effecting a change of control, encouraging the pursuit of special interests at the expense of a holistic, long-term strategic view or otherwise disrupting the effective functioning of the Board.
During 2017 and 2018, we have had further discussions with a number of our largest stockholders regarding our proxy access By-Law. Based on their feedback as well as a benchmarking review of proxy access rights adopted by other companies, we continue to believe that our current proxy access framework is most appropriate for the Company and our stockholders at this time.
We remain committed to corporate governance standards and practices that create long-term value for our stockholders. Key corporate governance practices that we have adopted include:
Annual election of Directors.
Majority voting for Directors, with a Director resignation policy, in uncontested Director elections.
10% threshold for stockholders to request a special meeting.
Ability of stockholders to act by written consent.
14 of the 15 Director nominees are independent with an average tenure of 7.5 years.
Proactive focus on Board composition and refreshment, including adding four new Directors to our Board in the past four years.
Strong Lead Independent Director.
All Board committees are comprised of independent Directors.
Annual Board and committee self-evaluations.
Proactive and robust stockholder engagement that includes participation of independent Directors.
Clawback policy under our Omnibus Plan.
Strong stock ownership guidelines for Directors and officers.
Annual management succession planning review.
Policy against hedging and pledging.
In light of our commitment to stockholder engagement and effective corporate governance as well as our meaningful, existing proxy access right, the Board believes that adoption of this stockholder proposal is not necessary and could be detrimental to stockholder value.

The Board recommends a vote AGAINST the stockholder proposal.

 Q 
      Can I attend the annual meeting?
   
A

All stockholders are invited to the annual meeting. Attendees need to bring photo identification, such as a driver’s license, and proof of ownership to gain admission to the annual meeting. If you are a holder of record, the top half of your proxy card is your proof of ownership. If you hold your shares in street name, you will need proof of ownership to be admitted to the annual meeting. Examples of proof of ownership are a recent brokerage statement or a letter from your bank or broker.

Please note that cameras, sound or video recording equipment, cellular telephones, smartphones or other similar equipment and electronic devices are not permitted to be used during the annual meeting. Large bags or backpacks may not be brought into the annual meeting.

If you hold your shares in street name and you want to give voting instructions at the annual meeting, you must get a legal proxy in your name from the broker, bank or other nominee that holds your shares.

 
 Q 
      What is notice and access?
   
A

The SEC’s notice and access rule allows companies to deliver a Notice of Internet Availability of Proxy Materials (Notice) to stockholders in lieu of a paper copy of the proxy statement and annual report. The Notice provides instructions as to how stockholders can access the proxy statement and the annual report online, contains a listing of matters to be considered at the annual meeting and sets forth instructions as to how shares can be voted. Instructions for requesting a paper copy of the proxy statement and the annual report are set forth on the Notice.

Shares must be voted by internet, by phone or by completing and returning a proxy form. Shares cannot be voted by marking, writing on and/ or returning the Notice. Any Notices that are returned will not be counted as votes.

 
 Q 
      How do I give voting instructions?
   
A
You may attend the annual meeting and give instructions in person or give instructions by internet, by phone or, if you received a printed proxy form, by mail. Information for giving voting instructions is on the Notice or form of proxy and trustee voting instruction form (proxy form).

For those investors whose shares are held by a broker, bank or other nominee, you must complete and return the voting instruction form provided by your broker, bank or nominee in order to instruct your broker, bank or nominee on how to vote.

FAQs about Voting and the Annual Meeting

 Q 
      What shares are included on the proxy form?
   
A

If you are a stockholder of record, you will receive only one Notice or proxy form for all the shares of common stock you hold in certificate form, in book-entry form and in any Company benefit plan.

Please vote proxies for all accounts to ensure that all of your shares are voted. If you wish to consolidate multiple registered accounts, contact EQ Shareowner Services at 1-800-554-7626 or at www.shareowneronline.com.

 
 Q 
      Will my shares be voted if I do not vote by internet, by telephone or by signing and returning my proxy form?
   
A

If you are a holder of record and you do not vote, then your shares will not count in deciding the matters presented for stockholder consideration at the annual meeting.

If you are a current or former Southern Company system employee or other individual who holds shares of common stock in the Southern Company ESP and you do not provide the trustee of the ESP (Trustee) with timely voting instructions, the Pension Fund Investment Review Committee may direct the Trustee how to vote these shares.

Procedures are in place to safeguard the confidentiality of your voting instructions.

If you are a beneficial owner, you will receive voting instruction information from the bank, broker or other nominee through which you own your shares of common stock.

If your shares are held through a bank, broker or other nominee, your broker may vote your shares under certain limited circumstances if you do not provide voting instructions before the annual meeting. These circumstances include voting your shares on routine matters under NYSE rules, such as the ratification of the appointment of our independent registered public accounting firm described in Item 3 of this proxy statement. With respect to Item 3, if you do not vote your shares, your bank or broker may vote your shares on your behalf or leave your shares unvoted. The remaining proposals are not considered routine matters under NYSE rules. When a proposal is not a routine matter and the brokerage firm has not received voting instructions, the brokerage firm cannot vote the shares on that proposal.

We encourage you to provide instructions to your broker or bank by voting your proxy so that your shares will be voted at the annual meeting in accordance with your wishes.

 
 Q 
      What if I am a stockholder of record and do not specify a choice for a matter when returning a proxy form?
   
A
Stockholders should specify their choice for each matter on the proxy form. If no specific instructions are given, proxies which are signed and returned will be voted in accordance with the Board’s recommendations.
 
 Q 
      Can I change my vote?
   
A

Yes. If you are a holder of record, you may change your vote by submitting a subsequent proxy, by written request received by the Corporate Secretary prior to the annual meeting or by attending the annual meeting and voting your shares.

If your shares are held through a broker, bank or other nominee, you must follow the instructions of your broker, bank or other nominee to revoke your voting instructions.

 
 Q 
      How are votes counted?
   
A
Each share counts as one vote.
 
 Q 
      How many votes do you need to hold the annual meeting?
   
A

A quorum is required to transact business at the annual meeting. Stockholders of record holding shares of stock constituting a majority of the shares entitled to be cast constitutes a quorum.

Abstentions that are marked on the proxy form and broker non-votes are included for the purpose of determining a quorum, but shares that otherwise are not voted are not counted toward a quorum.

 
 Q 
      What are broker non-votes?
   
A
Broker non-votes occur on a matter up for vote when a broker, bank or other holder of shares you own in “street name” is not permitted to vote on that particular matter without instructions from you, you do not give such instructions and the broker, bank or other nominee indicates on its proxy form, or otherwise notifies us, that it does not have authority to vote its shares on that matter. Whether a broker has authority to vote its shares on uninstructed matters is determined by NYSE rules.

 Q 
      What is “householding?”
   
A
Stockholders sharing a single address may receive only one copy of the proxy statement and annual report or the Notice, unless the transfer agent, broker, bank or other nominee has received contrary instructions from any owner at that address. This practice, known as householding, is designed to reduce printing and mailing costs. If a stockholder of record would like to either participate or cancel participation in householding, he or she may contact EQ Shareowner Services at 1-800-554-7626. If you own indirectly through a broker, bank or other nominee, please contact your financial institution.

Proposals must be submitted in writing to Corporate Secretary, Southern Company, 30 Ivan Allen Jr. Boulevard NW, Atlanta, Georgia 30308. The proxy solicited by the Board of Directors for the 2019 annual meeting will confer discretionary authority to vote on any stockholder proposal presented at that meeting that is not included in our proxy materials unless we are provided written notice of such proposal no later than February 20, 2019.
   
 Q 
      Who is soliciting my proxy and who pays the expense of such solicitations?
   
A

Your proxy is being solicited on behalf of the Board.

We pay the cost of soliciting proxies. We have retained D.F. King & Co. to assist with the solicitation of proxies for a fee of $12,500, plus additional fees for telephone and other solicitation of proxies or other services, if needed, and reimbursement of out-of-pocket expenses. Our officers or other employees may solicit proxies to have a larger representation at the meeting. None of these officers or other employees will receive any additional compensation for these services. Upon request, we will reimburse brokerage houses and other custodians, nominees and fiduciaries for their reasonable out-of-pocket expenses for forwarding solicitation material to the beneficial owners of the common stock.

(3) Earnings for the twelve months ended December 31, 2017, 2016 and 2015 include costs related to the acquisition and integration of Southern Company Gas and earnings for the twelve months ended December 31, 2017 include costs related to the pending dispositions of Elizabethtown Gas and Elkton Gas. Additionally, earnings for the twelve months ended December 31, 2016 include costs related to the acquisitions of PowerSecure International, Inc. and the 50% interest in SNG. Further costs are expected to continue to occur in connection with the integration activities for Southern Company Gas and closing the dispositions; however, the amount and duration of such expenditures is uncertain.
(4) Earnings for the twelve months ended December 31, 2015 include additional costs related to the discontinued operations of Mirant Corporation and the March 2009 litigation settlement with MC Asset Recovery, LLC. Further charges are not expected to occur.

Reconciliation of Non-GAAP Information

(5) Earnings for the twelve months ended December 31, 2017 and 2016 include the Wholesale Gas Services business of Southern Company Gas. Presenting earnings and earnings per share excluding Wholesale Gas Services provides investors with an additional measure of operating performance that excludes the volatility resulting from mark-to-market and lower of weighted average cost or current market price accounting adjustments.
(6) Earnings for the twelve months ended December 31, 2017 and 2016 include additional allowance for funds used during construction (AFUDC) equity as a result of extending the schedule for the Kemper IGCC construction project. AFUDC equity ceased in connection with the project’s suspension in June 2017. Southern Company’s 2017 earnings guidance, initially presented in October 2016, assumed construction would be complete and AFUDC equity would cease by November 30, 2016. Southern Company’s 2016 earnings guidance, initially presented in February 2016, assumed construction would be complete and AFUDC equity would cease by August 31, 2016. As a result, Southern Company believes presentation of earnings per share excluding AFUDC equity subsequent to August 31, 2016 provides investors with information comparable to guidance. Management also used such measures to evaluate Southern Company’s performance.
(7) Earnings for the twelve months ended December 31, 2017 include the net tax benefit as a result of federal tax reform legislation, which was signed into law on December 22, 2017. Southern Company’s 2017 earnings guidance, initially presented in October 2016, assumed no changes to tax laws. As a result, Southern Company believes presentation of earnings per share excluding this net tax benefit provides investors with information comparable to guidance. Management also used such measures to evaluate Southern Company’s performance. The impact of federal tax reform legislation ($21 million) on the Wholesale Gas Services business of Southern Company Gas is included in the adjustment above for Wholesale Gas Services.

Cautionary Note Regarding Forward-Looking Statements

Southern Company’s 2018 proxy statement contains forward-looking statements based on current expectations and plans that involve risks and uncertainties. Forward-looking statements include, among other things, statements concerning customer and stockholder value and the construction and startup of Plant Vogtle Units 3 and 4, including estimated in-service dates, expected receipt of additional DOE loan guarantees and projected tax benefits for customers. Southern Company cautions that there are certain factors that could cause actual results to differ materially from the forward-looking information that has been provided. The reader is cautioned not to put undue reliance on this forward-looking information, which is not a guarantee of future performance and is subject to a number of uncertainties and other factors, many of which are outside the control of Southern Company; accordingly, there can be no assurance that such suggested results will be realized.

The following factors, in addition to those discussed in Southern Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017, and subsequent securities filings, could cause actual results to differ materially from management expectations as suggested by such forward-looking information:

the impact of recent and future federal and state regulatory changes, including environmental laws regulating emissions, discharges and disposal to air, water and land, and also changes in tax and other laws and regulations to which Southern Company and its subsidiaries are subject, including federal tax reform legislation enacted in December 2017, as well as changes in application of existing laws and regulations;
the uncertainty surrounding the recently enacted federal tax reform legislation, including implementing regulations and Internal Revenue Service interpretations, actions that may be taken in response by regulatory authorities, and its impact, if any, on the credit ratings of Southern Company and its subsidiaries;
current and future litigation or regulatory investigations, proceedings or inquiries;
the effects, extent and timing of the entry of additional competition in the markets in which Southern Company’s subsidiaries operate;
variations in demand for electricity and natural gas, including those relating to weather, the general economy, population and business growth (and declines), the effects of energy conservation and efficiency measures, including from the development and deployment of alternative energy sources such as self-generation and distributed generation technologies, and any potential economic impacts resulting from federal fiscal decisions;
available sources and costs of natural gas and other fuels;
limits on pipeline capacity;
transmission constraints;
effects of inflation;
the ability to control costs and avoid cost overruns during the development, construction and operation of facilities, which include the development and construction of generating facilities with designs that have not been previously constructed, including changes in labor costs and productivity, adverse weather conditions, shortages and inconsistent quality of equipment, materials and labor, contractor or supplier delay, non-performance under construction, operating or other agreements, operational readiness, including specialized operator training and required site safety programs, unforeseen engineering or design problems, start-up activities (including major equipment failure and system integration) and/or operational performance;
the ability to construct facilities in accordance with the requirements of permits and licenses (including satisfaction of Nuclear Regulatory Commission requirements), to satisfy any environmental performance standards and the requirements of tax credits and other incentives and to integrate facilities into the Southern Company system upon completion of construction;
investment performance of the Southern Company system’s employee and retiree benefit plans and nuclear decommissioning trust funds;
advances in technology;
ongoing renewable energy partnerships and development agreements;

the possibility that the anticipated benefits from the merger with Southern Company Gas cannot be fully realized or may take longer to realize than expected and the possibility that costs related to the integration of Southern Company and Southern Company Gas will be greater than expected;
the ability of counterparties of Southern Company and its subsidiaries to make payments as and when due and to perform as required;
the ability to obtain new short- and long-term contracts with wholesale customers;
the direct or indirect effect on the Southern Company system’s business resulting from cyber intrusion or physical attacks and the threat of physical attacks;

changes in Southern Company’s and any of its subsidiaries’ credit ratings, including impacts on interest rates, access to capital markets and collateral requirements;
