Use of Estimates

The accounting principles the Company follows and the methods for applying these principles conform with U.S. GAAP and to those generally practiced within the banking industry. These accounting principles require management to make estimates and assumptions about future events that affect the amounts reported in the consolidated financial statements and the accompanying notes. Actual results could differ from those estimates.

Critical Accounting Policies and Estimates

2. Securities (continued)

The details for securities classified as held to maturity with unrealized losses for the periods indicated follow (in thousands):

The unrealized losses relate to changes in market rates on fixed-rate debt securities since the respective purchase date. In all cases, the indicated impairment would be recovered by the security’s maturity date or possibly earlier if the market price for the security increases with a reduction in the yield required by the market. None of the unrealized losses relate to the marketability of the securities or the issuer’s ability to meet contractual obligations. The Company has adequate liquidity and, therefore, does not plan to and, more likely than not, will not be required to sell these securities before recovery of the indicated impairment. Accordingly, the unrealized losses on these securities have been determined to be temporary.

Securities with carrying values totaling $2.9 billion at March 31, 2014 and $3.1 billion at December 31, 2013 were pledged primarily to secure public deposits or securities sold under agreements to repurchase.

3. Loans and Allowance for Loan Losses (continued)

The following briefly describes the distinction between originated, acquired and covered loans and certain significant accounting policies relevant to each category.

Originated loans

Loans originated for investment are reported at the principal balance outstanding net of unearned income. Interest on loans and accretion of unearned income, including deferred loan fees, are computed in a manner that approximates a level yield on recorded principal. Interest on loans is recognized in income as earned.

The accrual of interest on an originated loan is discontinued when, in management’s opinion, it is probable that the borrower will be unable to meet payment obligations as they become due, as well as when required by regulatory provisions. When accrual of interest is discontinued on a loan, all unpaid accrued interest is reversed and payments subsequently received are applied first to recover principal. Interest income is recognized for payments received after contractual principal has been satisfied. Loans are returned to accrual status when all the principal and interest contractually due are brought current and future payment performance is reasonably assured.

Acquired loans

Acquired loans are those loans that were purchased in the Whitney Holding Corporation acquisition on June 4, 2011. These loans were recorded at estimated fair value at the acquisition date with no carryover of the related allowance for loan losses. The acquired loans were segregated between those considered to be performing (“acquired-performing”) and those with evidence of credit deterioration (“acquired-impaired”) based on such factors as past due status, nonaccrual status and credit risk ratings (rated substandard or worse). The acquired loans were further segregated into loan pools designed to facilitate the development of expected cash flows to be used in estimating fair value.

Acquired-performing loans were segregated into pools based on characteristics such as loan type, credit risk ratings, and contractual interest rate and repayment terms. The major loan types included commercial and industrial loans not secured by real estate, real estate construction and land development loans, commercial real estate loans, residential mortgage loans, and consumer loans, with further segregation within certain loan types as needed. Expected cash flows, both principal and interest, from each pool were estimated based on key assumptions covering such factors as prepayments, default rates, and severity of loss given a default. These assumptions were developed using both Whitney Holding Corporation’s historical experience and the portfolio characteristics at acquisition as well as available market research.

The difference at the acquisition date between the fair value and the contractual amounts due of an acquired-performing loan pool (the “fair value discount”) is accreted into income over the estimated life of the pool. Acquired-performing loans are placed on nonaccrual status and reported as nonperforming or past due using the same criteria applied to the originated portfolio.

In addition to those factors considered for acquired-performing loans, the acquired-impaired loans were segregated into pools by identifying loans with similar credit risk profiles and were based primarily on characteristics such as loan type and market area in which originated. Loan types included most of the major types used for the acquired-performing portfolio. The acquired-impaired loans that had been originated in Louisiana and Texas were further disaggregated from loans originated in Mississippi, Alabama and Florida, in recognition of the differences in general economic conditions affecting borrowers in these market areas. The fair value estimate for each pool of acquired performing and acquired-impaired loans was based on the estimate of expected cash flows from the pool discounted at prevailing market rates.

3. Loans and Allowance for Loan Losses (continued)

The excess of estimated cash flows expected to be collected from an acquired-impaired loan pool over the pool’s carrying value is referred to as the accretable yield and is recognized in interest income using an effective yield method over the remaining life of the loan pool. Each pool of acquired-impaired loans is accounted for as a single asset with a single composite interest rate and an aggregate expectation of cash flows. Acquired-impaired loans in pools with an accretable yield and expected cash flows that are reasonably estimable are considered to be accruing and performing even though collection of contractual payments on loans within the pool may be in doubt, because the pool is the unit of accounting. Management recasts the estimate of cash flows expected to be collected on each acquired-impaired loan pool at each reporting date. If the present value of expected cash flows for a pool is less than its carrying value, impairment is recognized by an increase in the allowance for loan losses and a charge to the provision for loan losses. If the present value of expected cash flows for a pool is greater than its carrying value, any previously established allowance for loan losses is reversed and any remaining difference increases the accretable yield which will be taken into interest income over the remaining life of the loan pool. Acquired-impaired loans are generally not subject to individual evaluation for impairment and are not reported with impaired loans or troubled debt restructurings even if they would otherwise qualify for such treatment.

Covered loans and the related loss share receivable

The loans purchased in the 2009 acquisition of Peoples First Community Bank (Peoples First) are covered by two loss share agreements between the FDIC and the Company which afford the Company significant loss protection. These covered loans are accounted for as acquired-impaired loans as described above in the section on acquired loans. The Company treated all loans for the Peoples First acquisition under ASC 310-30 based on the significant amount of deteriorating and nonperforming loans comprised mainly of adjustable rate mortgages and home equity loans located in Florida. The loss share receivable is measured separately from the related covered loans as it is not contractually embedded in the loans and is not transferrable should the loans be sold. The fair value of the loss share receivable at acquisition was estimated by discounting expected reimbursements for losses from the loans covered by the loss share agreements, including appropriate consideration of possible true-up payments to the FDIC at the expiration of the agreements.

The loss share receivable is reviewed and updated prospectively as loss estimates related to covered loan pools change. Increases in expected reimbursements under the loss sharing agreements will lead to an increase in the loss share receivable. A decrease in expected reimbursements is reflected first as a reversal of any previously recorded increase in the loss share receivable on the covered loan pool with the remainder reflected as a reduction in the loss share receivable’s accretion rate. Increases and decreases in the loss share receivable related to changes in loss estimates result in reductions in or additions to the provision for loan losses, which serves to offset the impact on the provision from impairments or impairment reversals recognized on the underlying covered loan pool. The excess (or shortfall) of expected claims as compared to the carrying value of the loss share receivable is accreted (amortized) into noninterest income over the shorter of the remaining life of the covered loan pool or the life of the loss share agreement. The impact on operations of a reduction in the loss share receivable’s accretion rate is associated with an increase in the accretable yield on the underlying loan pool. The indemnification asset is reduced as cash is received from the FDIC related to losses incurred on covered assets.
