Hancock Holding Company and Subsidiaries

Notes to Consolidated Financial Statements

(Unaudited)

1. Basis of Presentation

The consolidated financial statements include the accounts of Hancock Holding Company and all other entities in which it has a controlling interest (the “Company”). The financial statements include all adjustments that are, in the opinion of management, necessary to present fairly the Company’s financial condition, results of operations, changes in stockholders’ equity and cash flows for the interim periods presented. Some financial information and disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the U.S. (U.S. GAAP) have been condensed or omitted in this Form 10-Q pursuant to Securities and Exchange Commission rules and regulations. These financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto included in the Company’s 2012 Annual Report on Form 10-K. Financial information reported in these financial statements is not necessarily indicative of the Company’s financial condition, results of operations, or cash flows for any other interim or annual period.

Use of Estimates

The accounting principles the Company follows and the methods for applying these principles conform with U.S. GAAP and with 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

Allowance for Loan Losses

The allowance for loan and lease losses (“ALLL”) is a valuation account available to absorb losses on loans. The ALLL is established and maintained at an amount sufficient to cover the estimated credit losses associated with the loan and lease portfolios of the Company as of the date of the determination. Credit losses arise not only from credit risk, but also from other risks inherent in the lending process including, but not limited to, collateral risk, operational risk, concentration risk, and economic risk. As such, all related risks of lending are considered when assessing the adequacy of the allowance for loan and lease losses. Quarterly, management estimates the inherent losses in the existing loan portfolio based on a number of factors, including the Company’s past loan loss and delinquency experience, known and inherent risks in the portfolio, adverse situations that may affect the borrowers’ ability to repay, the estimated value of any underlying collateral and current economic conditions.

The analysis and methodology for estimating the ALLL include two primary elements. These elements are a loss-rate analysis of various loan groups which incorporates a historical loss rate as updated for current conditions and a specific reserve analysis for those loans considered impaired.

1. Basis of Presentation (continued)

Critical Accounting Policies (continued)

During the second quarter of 2013, management revised the methodology for the loss-rate analysis for the originated and acquired performing loan portfolios due to the increased size and complexity of the Company’s commercial loan portfolio. The primary changes in the methodology were to segment loans with similar risk characteristics at a more granular level and to lengthen the period used for analyzing loss emergence and estimating loss factors. The changes were implemented as of April 1, 2013 and resulted in no material change in the total amount of the allowance for loan losses. Management made the following principal changes to the methodology during the second quarter of 2013:

• Established a more granular stratification of the major loan segments to enhance the homogeneity of the loan classes. Previously, the Company segmented loans into three primary groups—commercial, residential mortgage and consumer—for the loss-rate analysis. The revised loan segments are commercial non-real estate, construction and land development, commercial real estate, residential mortgage and consumer. Both quantitative and qualitative factors are applied at the more detailed portfolio segmentation.

• Included portfolio risk ratings in loss-rate analysis. For loss-rate analysis, commercial loans (commercial non-real estate, construction and land development and commercial real estate) are further subdivided by risk rating, and retail loans (residential mortgage and consumer) are further subdivided by delinquency. Previously, the methodology indirectly incorporated risk ratings and delinquencies.

• Lengthened the loss emergence period. The Company uses an eighteen month loss emergence period for commercial loans and a twelve month loss emergence period for retail loans. Historical loss rates are calculated for each commercial segment using a weighted average of three eighteen-month periods over a fourteen quarter look-back period, and for each retail segment using a weighted average of three twelve-month periods over a twelve quarter look-back period. Previously, historical loss rates were calculated using an average of three twelve month loss emergence periods over a three year look back period for all loan segments. As circumstances dictate, management will make adjustments to the loss history to reflect differences in current conditions as compared to those during the historical loss period. Conditions to be considered include problem loan trends, current business and economic conditions, credit concentrations, lending policies and procedures, lending staff, collateral values, loan profiles and volumes, loan review quality, and changes in competition and regulations.

There were no changes in the methodology for the specific reserve analysis on loans considered to be impaired or acquired credit-impaired loans during the quarter ended June 30, 2013.

There were no other material changes or developments with respect to methodologies that the Company uses when applying what management believes are critical accounting policies and developing critical accounting estimates as disclosed in our Form 10-K for the year ended December 31, 2012.

Substantially all of the unrealized losses relate to changes in market rates on fixed-rate debt securities since the respective purchase dates. In all cases, the indicated impairment would be recovered no later than 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 obligor’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 full recovery of the indicated impairment. Accordingly, the unrealized losses on these securities have been determined to be temporary.

Securities with carrying values totaling $2.8 billion at June 30, 2013 and $2.6 billion at December 31, 2012 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 are computed in a manner that approximates a level yield on recorded principal. Interest on loans is recorded as income as earned. The accrual of interest on an originated loan is discontinued when it is probable that the borrower will not be able to meet payment obligations as they become due. The Company maintains an allowance for loan losses on originated loans that represents management’s estimate of probable losses incurred in this portfolio category. The methodology for estimating the allowance is described in Note 1 to the Company’s Annual Report on Form 10-K for the year ended December 31, 2012. See Note 1 elsewhere in this document for updates to the allowance methodology for originated and acquired performing loans. As actual losses are incurred, they are charged against the allowance. Subsequent recoveries are added back to the allowance when collected.

Acquired loans

Acquired loans are those 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”), and then further segregated into loan pools designed to facilitate the development of expected cash flows. The factors considered in segregating the acquired portfolio are detailed in Note 1 to the Company’s Annual Report on Form 10-K for the year ended December 31, 2012. The fair value estimate for each pool of acquired performing and acquired impaired loans was based on the estimate of expected cash flows, both principal and interest, from that pool, discounted at prevailing market interest rates.

The difference between the fair value of an acquired performing loan pool and the contractual amounts due at the acquisition date (the “fair value discount”) is accreted into income over the estimated life of the pool. Management estimates an allowance for loan losses for acquired performing loans using a methodology similar to that used for originated loans. The allowance determined for each loan pool is compared to the remaining fair value discount for that pool. If the allowance is greater, the excess is added to the reported allowance through a provision for loan losses. If the allowance is less, no additional allowance or provision is recognized. Actual losses first reduce any remaining fair value discount for the loan pool. Once the discount is fully depleted, losses are applied against the allowance established for that pool. Acquired performing loans are placed on nonaccrual status and considered and reported as nonperforming or past due using the same criteria applied to the originated portfolio.

The excess of cash flows expected to be collected from an acquired impaired loan pool over the pool’s estimated fair value at acquisition is referred to as the accretable yield and is recognized in interest income using an effective yield method over the remaining life of the 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.

3. Loans and Allowance for Loan Losses (continued)

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, an 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 that afford the Company significant loss protection. These covered loans are accounted for as acquired impaired loans as described above. The loss share receivable is measured separately from the related covered loans as it is not contractually embedded in the loans and is not transferable should the loans be sold. The fair value of the loss share receivable at acquisition was estimated by discounting projected cash flows related to the loss share agreements based on the expected reimbursements for losses using the applicable loss share percentages, including appropriate consideration of possible true-up payments to the FDIC at the expiration of the agreements. The discounted amount is accreted into non-interest income over the remaining life of the covered loan pool or the life of the loss share agreement.

The loss share receivable is reviewed and updated prospectively as loss estimates related to the covered loans change. Increases in expected reimbursements under the loss sharing agreements from a covered loan pool 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 can result in reductions in or additions to the provision for loan losses, which serve to offset the impact on the provision from impairment recognized on the underlying covered loan pool and reversals of previously recognized impairment. 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.

(a) The $2.6 million provision expense for impairment of certain pools of covered loans is reported net of the benefit attributable to the FDIC loss share agreement, as reflected by the related increase in the loss share receivable.

(b) In accordance with purchase accounting rules, the Whitney loans were recorded at their fair value at the time of the acquisition, and the prior allowance for loan losses was eliminated. No allowance had been established on these acquired loans since the acquisition date through June 30, 2012. These loans are included in the ending balance of loans collectively evaluated for impairment.

The following tables show the composition of nonaccrual loans by portfolio segment and class. Acquired impaired and certain covered loans are considered to be performing due to the application of the accretion method and are excluded from the table. Covered loans accounted for using the cost recovery method do not have an accretable yield and are disclosed below as nonaccrual loans. Acquired performing loans that have subsequently been placed on nonaccrual status are also disclosed below.

The amount of interest that would have been recorded on nonaccrual loans and taken into income for the six months ended June 30, 2013 was approximately $3.7 million. Interest actually received on nonaccrual loans during the six months ended June 30, 2013 was $2.1 million.

Included in nonaccrual loans at June 30, 2013 is $20.6 million in restructured commercial loans. Total troubled debt restructurings (TDRs) were $33.7 million as of June 30, 2013 and $32.2 million at December 31, 2012. Acquired and covered impaired loans modified post-acquisition are not removed from their accounting pool and accounted for as TDRs, even if those loans would otherwise be deemed TDRs.

Loan review uses a risk-focused continuous monitoring program that provides for an independent, objective and timely review of credit risk within the company. Below are the definitions of the Company’s internally assigned grades:

Commercial:

• Pass - loans properly approved, documented, collateralized, and performing which do not reflect an abnormal credit risk.

• Pass - Watch - Credits in this category are of sufficient risk to cause concern. This category is reserved for credits that display negative performance trends. The “Watch” grade should be regarded as a transition category.

• Special Mention - These credits exhibit some signs of “Watch,” but to a greater magnitude. These credits constitute an undue and unwarranted credit risk, but not to a point of justifying a classification of “Substandard.” They have weaknesses that, if not checked or corrected, weaken the asset or inadequately protect the bank.

• Substandard - These credits constitute an unacceptable risk to the bank. They have recognized credit weaknesses that jeopardize the repayment of the debt. Repayment sources are marginal or unclear.

• Doubtful - A Doubtful credit has all of the weaknesses inherent in one classified “Substandard” with the added characteristic that weaknesses make collection in full highly questionable or improbable.

3. Loans and Allowance for Loan Losses (continued)

• Loss - Credits classified as Loss are considered uncollectable and are charged off promptly once so classified.

Consumer:

• Performing – Loans on which payments of principal and interest are less than 90 days past due.

• Nonperforming – Loans on which payments of principal and interest are more than 90 days past due and on nonaccrual status.

Changes in the carrying amount of acquired impaired loans and accretable yield are presented in the following table for the six months ended June 30, 2013 and the year ended December 31, 2012:

4. Fair Value

The Financial Accounting Standards Board (FASB) defines fair value as the exchange price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The FASB’s guidance also established a fair value hierarchy that prioritizes the inputs to these valuation techniques used to measure fair value, giving preference to quoted prices in active markets for identical assets or liabilities (level 1) and the lowest priority to unobservable inputs such as a reporting entity’s own data (level 3). Level 2 inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical assets or liabilities in markets that are not active, observable inputs other than quoted prices, such as interest rates and yield curves, and inputs that are derived principally from or corroborated by observable market data by correlation or other means.

4. Fair Value (continued)

Securities classified as level 1 within the valuation hierarchy include U.S. Treasury securities, obligations of U.S. Government-sponsored agencies, and certain other debt and equity securities. Level 2 classified securities include residential mortgage-backed securities and collateralized mortgage obligations that are issued or guaranteed by U.S. government agencies, and state and municipal bonds. The level 2 fair value measurements for investment securities are obtained quarterly from a third-party pricing service that uses industry-standard pricing models. Substantially all of the model inputs are observable in the marketplace or can be supported by observable data. The Company invests only in high quality securities of investment grade quality with a targeted duration, for the overall portfolio, generally between two to five years. Company policies limit investments to securities having a rating of not less than “Baa” or its equivalent by a nationally recognized statistical rating agency. There were no transfers between valuation hierarchy levels during the periods shown.

The fair value of derivative financial instruments, which are predominantly interest rate swaps, is obtained from a third-party pricing service that uses an industry-standard discounted cash flow model that relies on inputs, such as LIBOR swap curves and Overnight Index Swap rate (“OIS”) curves, observable in the marketplace. To comply with the accounting guidance, credit valuation adjustments are incorporated in the fair values to appropriately reflect nonperformance risk for both the Company and the counterparties. Although the Company has determined that the majority of the inputs used to value the derivative instruments fall within level 2 of the fair value hierarchy, the credit value adjustments utilize level 3 inputs, such as estimates of current credit spreads. The Company has determined that the impact of the credit valuation adjustments is not significant to the overall valuation of these derivatives. As a result, the Company has classified its derivative valuations in their entirety in level 2 of the fair value hierarchy. The Company’s policy is to measure counterparty credit risk quarterly for all derivative instruments subject to master netting arrangements consistent with how market participants would price the net risk exposure at the measurement date.

The Company also has certain derivative instruments associated with the Banks’ mortgage-banking activities. These derivative instruments include interest rate lock commitments on prospective residential mortgage loans and forward commitments to sell these loans to investors on a best efforts delivery basis. The fair value of these derivative instruments is measured using observable market prices for similar instruments and classified as level 2 measurements.

Fair Value of Assets Measured on a Nonrecurring Basis

Certain assets and liabilities are measured at fair value on a nonrecurring basis. Collateral-dependent impaired loans are level 2 assets measured at the fair value of the underlying collateral based on third-party appraisals that take into consideration prices in observed transactions or other market-based information such as recent sales activity for similar assets in the property’s market.

4. Fair Value (continued)

Other real estate owned are level 3 assets that are adjusted to fair value, less estimated selling costs, upon transfer to other real estate owned. Subsequently, other real estate owned is carried at the lower of carrying value or fair value less estimated selling costs. Fair values are determined by sales agreement or third-party appraisals as discounted for estimated selling costs, information from comparable sales, and marketability of the property.

The following tables present for each of the fair value hierarchy levels the Company’s financial assets that are measured at fair value (in thousands) on a nonrecurring basis.

Accounting guidance from the FASB requires the disclosure of estimated fair value information about certain on- and off-balance sheet financial instruments, including those financial instruments that are not measured and reported at fair value on a recurring basis. The significant methods and assumptions used by the Company to estimate the fair value of financial instruments are discussed below.

Cash, Short-Term Investments and Federal Funds Sold - For these short-term instruments, the carrying amount is a reasonable estimate of fair value.

Securities – The fair value measurement for securities available for sale was discussed earlier. The same measurement techniques were applied to the valuation of securities held to maturity.

Loans, Net - The fair value measurement for certain impaired loans was discussed earlier. For the remaining portfolio, fair values were generally determined by discounting scheduled cash flows by discount rates determined with reference to current market rates at which loans with similar terms would be made to borrowers of similar credit quality.

Accrued Interest Receivable and Accrued Interest Payable - The carrying amounts are a reasonable estimate of fair value.

4. Fair Value (continued)

Deposits - The accounting guidance requires that the fair value of deposits with no stated maturity, such as noninterest-bearing demand deposits, interest-bearing checking and savings accounts, be assigned fair values equal to amounts payable upon demand (carrying amounts). The fair value of fixed-maturity certificates of deposit is estimated using the rates currently offered for deposits of similar remaining maturities.

Securities Sold under Agreements to Repurchase and Federal Funds Purchased - For these short-term liabilities, the carrying amount is a reasonable estimate of fair value.

Long-Term Debt - The fair value is estimated by discounting the future contractual cash flows using current market rates at which debt with similar terms could be obtained.

Derivative Financial Instruments – The fair value measurement for derivative financial instruments was discussed earlier.

The following tables present the estimated fair values of the Company’s financial instruments by fair value hierarchy levels and the corresponding carrying amount at June 30, 2013 and December 31, 2012 (in thousands):

Risk Management Objective of Using Derivatives

The Company enters into derivative financial instruments to manage risks related to differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments, currently related to our variable rate borrowing. The Banks have also entered into interest rate derivative agreements as a service to certain qualifying customers. The Banks manage a matched book with respect to these customer derivatives in order to minimize the net risk exposure resulting from such agreements. The Banks also enter into risk participation agreements under which they may either sell or buy credit risk associated with a customer’s performance under certain interest rate derivative contracts related to loans in which participation interests have been sold to or purchased from other banks.

Fair Values of Derivative Instruments on the Balance Sheet

The table below presents the notional amounts and fair values (in thousands) of the Company’s derivative financial instruments as well as their classification on the consolidated balance sheets as of June 30, 2013 and December 31, 2012.

(2) The notional amount represents both the customer accommodation agreements and offsetting agreements with unrelated financial institutions.

Cash Flow Hedges of Interest Rate Risk

The Company had been party to an interest rate swap agreement with a notional amount of $140 million under which the Company received interest at a variable rate and paid at a fixed rate. This derivative instrument represented by this swap agreement was designated as and qualified as a cash flow hedge of the Company’s forecasted variable cash flows under a variable-rate term borrowing agreement. The swap agreement expired in June 2013.

During the term of the swap agreement, the effective portion of changes in the fair value of the derivative instrument was recorded in accumulated other comprehensive income (“AOCI”) and subsequently reclassified into earnings in the periods that the hedged forecasted variable-rate interest payments affected earnings. The impact on AOCI was insignificant during 2013 and 2012. There was no ineffective portion of the change in fair value of the derivative recognized directly in earnings.

Derivatives Not Designated as Hedges

Customer interest rate derivatives

The Banks enter into interest rate derivative agreements, primarily rate swaps, with commercial banking customers to facilitate their risk management strategies. The Banks simultaneously enter into offsetting agreements with unrelated financial institutions, thereby mitigating its net risk exposure resulting from such transactions. Because the interest rate derivatives associated with this program do not meet hedge accounting requirements, changes in the fair value of both the customer derivatives and the offsetting derivatives are recognized directly in earnings.

5. Derivatives (continued)

Risk participation agreements

The Banks also enter into risk participation agreements under which they may either assume or sell credit risk associated with a borrower’s performance under certain interest rate derivative contracts. In those instances where the Banks have assumed credit risk, they are not a direct counterparty to the derivative contract with the borrower and have entered into the risk participation agreement because they are a party to the related loan agreement with the borrower. In those instances in which the Banks have sold credit risk, they are the sole counterparty to the derivative contract with the borrower and have entered into the risk participation agreement because other banks participate in the related loan agreement. The Banks manage their credit risk under risk participation agreements by monitoring the creditworthiness of the borrower, based on their normal credit review process.

Mortgage banking derivatives

The Banks also enter into certain derivative agreements as part of their mortgage banking activities. These agreements include interest rate lock commitments on prospective residential mortgage loans and forward commitments to sell these loans to investors on a best efforts delivery basis.

Effect of Derivative Instruments on the Income Statement

The effect of the Company’s derivative financial instruments on the income statement was immaterial for the three month and six month periods ended June 30, 2013 and 2012.

Credit-risk-related Contingent Features

Certain of the Banks’ derivative instruments contain provisions allowing the financial institution counterparty to terminate the contracts in certain circumstances, such as the downgrade of the Banks’ credit ratings below specified levels, a default by the Bank on its indebtedness, or the failure of a Bank to maintain specified minimum regulatory capital ratios or its regulatory status as a well-capitalized institution. These derivative agreements also contain provisions regarding the posting of collateral by each party. As of June 30, 2013, the aggregate fair value of derivative instruments with credit-risk-related contingent features that were in a net liability position was $8.7 million, for which the Banks had posted collateral of $6.2 million.

6. Stockholders’ Equity

Stock Repurchase Program

The Company’s board of directors approved a stock repurchase program on April 30, 2013 that authorizes the repurchase of up to 5% of the Company’s outstanding common stock.

On May 8, 2013 Hancock entered into an accelerated share repurchase (“ASR”) transaction with Morgan Stanley & Co. LLC (“Morgan Stanley”). In the ASR transaction, the Company paid $115 million to Morgan Stanley and received from them approximately 2.8 million shares of Hancock common stock, representing approximately 70% of the estimated total number of shares to be repurchased. The actual number of shares to be delivered to the Company in this ASR transaction will be based generally on the volume-weighted average price per share of the Hancock common stock during the term of the ASR agreement less a specified discount and on the amount paid at inception to Morgan Stanley, subject to certain possible adjustments in accordance with the terms of the ASR agreement. Final settlement of the ASR agreement is scheduled to occur no earlier than November, 2013 and no later than May, 2014. The ASR transaction was treated as two separate transactions: (i) the acquisition of treasury shares on the date the shares were received; and (ii) a forward contract indexed to the Company’s common stock that is classified as equity.

Accumulated Other Comprehensive Income (Loss)

Accumulated other comprehensive income (loss) (AOCI) is reported as a component of stockholders’ equity. AOCI can include, among other items, unrealized holding gains and losses on securities available for sale (AFS), gains and losses associated with pension or other post retirement benefits that are not recognized immediately as a component of net periodic benefit cost, and gains and losses on derivative instruments that are designated as, and qualify as, cash flow hedges. The net unrealized gain on AFS securities reclassified as securities held to maturity (HTM) during 2012 also continues to be reported as a component of AOCI and will be amortized over the estimated remaining life of the securities as an adjustment to interest income. The components of AOCI are reported net of related tax effects. The components of AOCI and changes in those components are presented in the following table (in thousands).

7. Earnings Per Share

Hancock calculates earnings per share using the two-class method. The two-class method allocates net income to each class of common stock and participating security according to common dividends declared and participation rights in undistributed earnings. Participating securities consist of unvested stock-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents.

Following is a summary of the information used in the computation of earnings per common share using the two-class method (in thousands, except per share amounts):

	Three Months Ended June 30,				Six Months Ended June 30,
	2013		2012		2013		2012
Numerator:
Net income to common shareholders	$	46,862	$	39,304	$	95,438	$	57,799
Net income allocated to participating securities - basic and diluted		880		294		1,782		587
Net income allocated to common shareholders - basic and diluted	$	45,982	$	39,010	$	93,656	$	57,212
Denominator:
Weighted-average common shares - basic		83,279		84,751		84,071		84,742
Dilutive potential common shares		78		749		82		725
Weighted average common shares - diluted		83,357		85,500		84,153		85,467
Earnings per common share:
Basic	$	0.55	$	0.46	$	1.11	$	0.68
Diluted	$	0.55	$	0.46	$	1.11	$	0.67

Potential common shares consist of employee and director stock options. These potential common shares do not enter into the calculation of diluted earnings per share if the impact would be anti-dilutive, i.e., increase earnings per share or reduce a loss per share. Weighted-average anti-dilutive potential common shares totaled 1,433,249 and 1,298,940 respectively for the three and six months ended June 30, 2013 and 1,107,467 and 954,326 respectively for the three and six months ended June 30, 2012.

8. Share-Based Payment Arrangements

Hancock maintains incentive compensation plans that provide for awards of share-based compensation to employees and directors. These plans have been approved by the Company’s shareholders. Detailed descriptions of these plans were included in Note 13 to the consolidated financial statements in the Company’s annual report on Form 10-K for the year ended December 31, 2012.

A summary of option activity for the six months ended June 30, 2013 is presented below:

Options	Number of Shares			Weighted- Average Exercise Price ($)		Weighted- Average Remaining Contractual Term (Years)		Aggregate Intrinsic Value ($000)
Outstanding at January 1, 2013		1,555,296		$	38.57
Exercised		(7,134	)		23.73
Forfeited or expired		(70,443	)		47.66
Outstanding at June 30, 2013		1,477,719		$	38.21		4.9	$	247
Exercisable at June 30, 2013		1,024,893		$	40.95		3.6	$	192

The total intrinsic value of options exercised during the six months ended June 30, 2013 and 2012 was $0.1 million and $0.4 million, respectively.

A summary of the status of the Company’s nonvested restricted and performance shares as of June 30, 2013 and changes during the six months ended June 30, 2013, is presented below. These restricted and performance shares are subject to service requirements.

	Number of Shares			Weighted- Average Grant-Date Fair Value  ($)
Nonvested at January 1, 2013		1,684,360		$	31.56
Granted		93,936			32.03
Vested		(23,827	)		37.00
Forfeited		(42,690	)		31.46

8. Share-Based Payment Arrangements (continued)

As of June 30, 2013, there was $33.2 million of total unrecognized compensation expense related to nonvested restricted and performance shares expected to vest. This compensation is expected to be recognized in expense over a weighted-average period of 3.3 years. The total fair value of shares which vested during the six months ended June 30, 2013 and 2012 was $0.7 million and $0.8 million, respectively.

During the six months ended June 30, 2013, the Company granted 67,533 performance shares with an average fair value of $32.84 per share to key members of executive and senior management. The number of 2013 performance shares that ultimately vest at the end of the three-year required service period will be based on the relative rank of Hancock’s three-year total shareholder return (TSR) among the TSRs of a peer group of fifty regional banks. The maximum number of performance shares that could vest is 200% of the target award. The fair value of the performance awards at the grant date was determined using a Monte Carlo simulation method. Compensation expense for these performance shares will be recognized on a straight-line basis over the service period.

9. Retirement Plans

Effective January 1, 2013, the Company adopted one qualified defined benefit pension plan covering all eligible employees. Eligibility is based on minimum age and service-related requirements as well as job classification. The consolidated plan replaced the separate qualified plans covering legacy Hancock employees (Hancock Plan) and legacy Whitney employees (Whitney Plan). The new qualified plan terms are substantially the same for legacy Hancock employees as those in effect at December 31, 2012 under the Hancock Plan. Retirement benefits for eligible legacy Whitney employees under the new plan will be based on the employee’s accrued benefit under the Whitney Plan as of December 31, 2012 plus any benefit accrued under the new plan based on years of service and compensation beginning in 2013. The Whitney Plan had been closed to new participants since 2008, and benefit accruals had been frozen for all participants other than those meeting certain vesting, age and years of service criteria as of December 31, 2008. Accrued benefits under the nonqualified plan covering certain legacy Whitney employees were frozen as of December 31, 2012 and no future benefits will be accrued under this plan.

The Company also sponsors defined benefit postretirement plans for both legacy Hancock and legacy Whitney employees that provide health care and life insurance benefits. Benefits under the Hancock plan are not available to employees hired on or after January 1, 2000. Benefits under the Whitney plan are restricted to retirees who were already receiving benefits at the time of plan amendments in 2007 or active participants who were eligible to receive benefits as of December 31, 2007.

Net periodic benefit cost	$	5,486		$	5,689		$	1,631	$	1,147

The Company anticipates a total contribution to the pension plan of $10 million for 2013.

Effective January 1, 2013, the Company also combined the Hancock and Whitney defined contribution retirement benefit plans (401(k) plans). Under the combined plan, the Company matches 100% of the first 1% of compensation saved by a participant, and 50% of the next 5% of compensation saved. Under the prior Hancock 401(k) plan, the Company matched 50% of a participant’s savings up to 6% of compensation, while under the prior Whitney 401(k) plan, the Company matched 100% of a participant’s savings up to 4% of compensation. The Company could also make a discretionary profit sharing contribution under the Whitney plan on behalf of participants who were either ineligible to participate in the Whitney qualified defined-benefit pension plan or subject to the freeze in benefit accruals under that plan. With the adoption of the new qualified pension plan discussed above and the combined 401(k) plan, the discretionary profit-sharing contribution is no longer available for plan years beginning in 2013.

12. Segment Reporting

The Company’s reportable operating segments consist of the Hancock segment, which coincides generally with the Company’s Hancock Bank subsidiary, and the Whitney segment, which coincides generally with its Whitney Bank subsidiary. Each of the bank segments offers commercial, consumer and mortgage loans and deposit services as well as certain other services, such as trust and treasury management services. Although the bank segments offer the same products and services, they are managed separately due to different pricing, product demand, and consumer markets. In addition, the “Other” column in the following tables includes activities of other consolidated subsidiaries which do not constitute reportable segments under the quantitative and aggregation accounting guidelines. These subsidiaries provide investment services, insurance agency services, insurance underwriting and various other services to third parties.

13. New Accounting Pronouncements

In June, the Financial Accounting Standards Board (FASB) issued an Emerging Issues Task Force (EITF) regarding companies with unrecognized tax benefits that have deferred tax assets recorded for net operating loss (NOL) or tax credit carryforwards. An entity should present its unrecognized tax benefits net against the deferred tax assets for all same jurisdiction NOL or similar tax loss carryforwards (e.g., capital losses), or tax credit carryforwards that are available and would be used by the entity to settle additional income taxes resulting from disallowance of the uncertain tax position. Netting will not be limited to only those instances when an unrecognized tax benefit is directly associated with a tax position taken in the same tax year that resulted in recognition of the NOL or tax credit carryforward for that year. The task force decided not to require any new disclosures. However, a public entity will still be required to include the unrecognized tax benefit within its existing income tax disclosures. The changes will be effective for public entities for annual periods (and interim periods within those annual periods) beginning after December 15, 2013. The adoption of this guidance is not expected to have a material impact on the Company’s financial condition or results of operations.

13. New Accounting Pronouncements (continued)

In February 2013, the FASB issued an Accounting Standards Update (ASU) to improve the reporting of amounts reclassified out of accumulated other comprehensive income. The updated guidance requires an entity to present, either on the face of the statement where net income is presented or in the notes, the effects on the line items of net income of significant amounts reclassified out of accumulated other comprehensive income, but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income, an entity must cross-reference to other required disclosures that provide additional details about those amounts. This ASU is effective for interim and annual reporting periods beginning after December 15, 2012. Because this updated guidance impacts only disclosures in financial statements and does not change the current requirements for reporting net income or other comprehensive income in financial statements, its implementation did not impact the Company’s financial condition or results of operations.

In October 2012, the FASB issued an ASU for entities that recognize an indemnification asset as a result of a government-assisted acquisition of a financial institution. When there is a change in the cash flows expected to be collected on the indemnification asset as a result of a change in cash flows expected to be collected on the assets subject to indemnification, the reporting entity should subsequently account for the change in the measurement of the indemnification asset on the same basis as the change in the assets subject to indemnification. Any amortization of changes in value should be limited to the contractual term of the indemnification agreement (that is, the lesser of the term of the indemnification agreement and the remaining life of the indemnified assets). The amendments in this update are effective for fiscal years, and interim periods within those years, beginning on or after December 15, 2012. The updated guidance will be applied prospectively to any new indemnification assets acquired after the date of adoption and to indemnification assets existing as of the date of adoption arising from a government-assisted acquisition of a financial institution. The Company’s current accounting policy complies with the guidance in this update.

In July 2012, FASB issued an ASU that specifies that an entity has the option first to assess qualitative factors to determine whether the existence of events and circumstances indicates that it is more likely than not that the indefinite-lived intangible asset is impaired. If, after assessing the totality of events and circumstances, an entity concludes that it is not more likely than not that the indefinite-lived intangible asset is impaired, then the entity is not required to take further action. However, if an entity concludes otherwise, then it is required to determine the fair value of the indefinite-lived intangible asset and perform the quantitative impairment test by comparing the fair value with the carrying amount. Under the guidance in this ASU, an entity also has the option to bypass the qualitative assessment for any indefinite-lived intangible asset in any period and proceed directly to performing the quantitative impairment test. An entity will be able to resume performing the qualitative assessment in any subsequent period. The guidance in this ASU is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012, with early adoption permitted. The adoption of this guidance did not have a material impact on the Company’s financial condition or results of operations.

13. New Accounting Pronouncements (continued)

In December 2011, the FASB issued an ASU to address the differences between international financial reporting standards (IFRS) and U.S. GAAP regarding the offsetting of assets and liabilities. Instead of proposing new criteria for netting assets and liabilities the FASB and International Accounting Standards Board (IASB) jointly issued common disclosure requirements related to offsetting arrangements that call for the disclosure of both net and gross information for these assets and liabilities, irrespective of whether they are offset on the statement of financial position. In January 2013, the FASB clarified that these disclosure requirements apply only to derivatives, repurchase and reverse repurchase agreements, and securities borrowing and lending transactions that are either offset in accordance with existing accounting guidance or subject to a master netting arrangement or similar agreement. An entity is required to provide the new disclosures for annual and interim reporting periods beginning on or after January 1, 2013. This guidance impacts only the disclosures in financial statements and did not impact the Company’s financial condition or results of operations.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

OVERVIEW

Recent Economic and Industry Developments

Recent reports from the Federal Reserve point to continued improvement of economic activity throughout most of Hancock’s market area. Activity at energy related businesses operating mainly in Hancock’s south Louisiana and Houston, Texas market areas remained at high levels with expectations of further improvement in the second half of 2013. The travel and tourism industry, which is important to several of the Company’s market areas, continues to see strong demand that exceeds expectations and is forecast to continue into 2014. Retailers are showing mixed results, but recent sales activity continues to exceed prior year levels and a steady rate of growth is expected in the near term. The Texas retail market continues to be a top performer. Consumer spending should be supported by relatively stable prices, modest improvement in labor markets and rising home values, but consumers remain cautious and generally conservative in their spending behavior. Reports on manufacturing activity were generally positive, with expectations of continued improvement for the remainder of 2013.

The real estate markets for both residential and commercial properties continue to show improvement. Sales of existing homes continued to grow, outpacing supply and putting upward pressure on home prices. Sales activity was strongest in our Florida and Texas markets. New home sales and construction are ahead of prior year levels and growing, but demand exceeds supply as some builders have had difficulties with financing and with a shortage of developed lots.

The commercial real estate market continues to improve, with growing demand for office and industrial space in certain market areas and continued high occupancy and rising rental rates for apartments throughout the region. Commercial construction activity has increased in these sectors, although a wider variety of projects may be in the planning stages.

The recovery of the overall U.S. economy continues; however, the rate of growth is not consistent across all regions leading to slow and erratic overall improvement. National unemployment rates continue to decrease, but are still well above desired levels. Competition among financial services firms remains intense for high quality customers, with downward pressure on loan pricing.

The Federal Reserve has responded to the slow and tenuous recovery from the deep recession by taking steps to hold interest rates at unprecedented low levels and has expressed its intent to maintain rates at these levels pending further improvement in the unemployment rate.

Highlights of Second Quarter 2013 Financial Results

Net income for the second quarter of 2013 was $46.9 million, or $0.55 per diluted common share, compared to $48.6 million, or $0.56 per diluted common share, in the first quarter of 2013. Net income was $39.3 million, or $0.46 per diluted common share, in the second quarter of 2012, which included pre-tax merger-related expenses of $11.9 million.

Included in the Company’s second quarter 2013 results are:

• Approximately $245 million linked-quarter net loan growth, or 9% annualized, and over $760 million, or 7%, year-over-year loan growth (each excluding the FDIC-covered portfolio).

• Core net interest income (TE) and net interest margin (NIM) remained relatively stable compared to the first quarter of 2013, and combined with growth in fee income, led to improved core revenue.

• Continued improvement in overall asset quality metrics.

49

• Initiated a 5% common stock buyback in May through an accelerated share repurchase (ASR) program, receiving 2.8 million shares to-date.

The Company defines its core results as reported results less the impact of total net purchase accounting adjustments. A reconciliation of the reported net interest margin to core margin is provided in the discussion of “Net Interest Income” below.

Management expects earnings to remain flat to slightly down from current levels for the remainder of 2013, as expected declines and volatility in purchase-accounting loan accretion and other adjustments continue to impact reported results.

The Company remains on track to achieve its efficiency and expense reduction target for the first quarter of 2014. In May of 2013, the Company announced the planned closing of approximately 40 branch locations across its 5-state footprint as part of the expense reduction initiative. In late July 2013, the Company announced agreements to sell 10 of these 40 branch locations. A significant portion of the cost savings targeted for the first quarter of 2014 will be derived from these closures and sales. Currently, the Company plans to close the majority of the branches on August 30, 2013, with the remaining branches scheduled to close or be sold by year-end. Management expects one-time costs associated with the branch sales and closures to be booked in the third quarter of 2013. These costs are expected to be lower than previous guidance of between $18 and $22 million. The branch sales, which are subject to regulatory approvals and certain closing conditions, will be reflected in Hancock’s fourth quarter 2013 financial results. The buyers expect to acquire approximately $54 million in loans and $60 million in deposits booked in these 10 retail branches.

Hancock’s return on average assets (ROA) was 0.99% for the second quarter of 2013, compared to 1.03% in the first quarter of 2013 and 0.83% in the second quarter of 2012. ROA was 1.00% in the second quarter of 2012 on an operating basis, which excludes tax-effected merger-related expenses in that period.

Common shareholders’ equity totaled $2.3 billion at June 30, 2013, down almost $132 million from March 31, 2013. The tangible common equity (TCE) ratio declined 62 basis points (bps) to 8.52% at June 30, 2013. The linked-quarter decline mainly reflects the $115 million (63 bps) used in May 2013 to execute the ASR program to repurchase Hancock Holding Company outstanding common stock. Additionally, while the Company continued to add to its strong capital base through retained earnings, accumulated other comprehensive income (a component of equity) declined $47 million (26 bps) from March 31, 2013. The decline mainly reflects the impact of increased market rates on the valuation of the securities portfolio.

RESULTS OF OPERATIONS

Net Interest Income

Net interest income (taxable equivalent or TE) for the second quarter of 2013 totaled $171.8 million, a $4.9 million (3%) decline from the first quarter of 2013. Approximately $4.4 million of this decline was related to a lower level of total purchase-accounting loan accretion on acquired loans in the second quarter of 2013, mainly related to the volatility in excess cash recoveries, as detailed below in the table reconciling the Company’s reported net interest margin to its core margin. Excess cash recoveries include cash collected on certain acquired loan pools with a zero carrying value. Average earning assets were virtually unchanged between these quarterly periods. For internal analytical purposes, management adjusts net interest income to a “taxable equivalent” basis using a 35% federal tax rate on tax exempt items (primarily interest on municipal securities and loans).

Net interest income (TE) for the second quarter of 2013 was down $8.5 million (5%) compared to the second quarter of 2012, primarily due to declining loan and investment yields. Total net purchase-accounting adjustments increased net interest income (TE) in the second quarter of 2013 by an additional $5.3 million compared to the second quarter of 2012. Average earning assets for the second quarter of 2013 were up $344 million compared to second quarter of 2012, driven mainly by net loan growth.

The reported net interest margin (TE) for the second quarter of 2013 was 4.17%, down 15 basis points (bps) from the first quarter of 2013 and down 31 bps from the second quarter of 2012. The current quarter’s core margin of 3.38% compressed approximately 3 bps compared to the first quarter of 2013 and approximately 42 bps compared to the second quarter of 2012, mainly from a decline in the core yields on the loan and securities portfolios. The core margin represents reported net interest income (TE) excluding total annualized net purchase-accounting adjustments as a percent of average earning assets. A reconciliation of the Company’s reported and core margins is presented below.

The overall reported yield on earning assets was 4.42% in the second quarter of 2013, a decrease of 18 bps from the first quarter of 2013 and 38 bps from the second quarter of 2012. The reported loan portfolio yield of 5.47% for the current quarter was down 36 bps from the first quarter of 2013 and 57 bps from the second quarter of 2012. Excluding purchase-accounting accretion, the core loan yield of 4.23% in the current quarter was down 18 bps from the first quarter of 2013 and 61 bps from a year earlier. Recent activity in commercial lending has been in very competitively priced segments. The average rates on all new loans booked in the second quarter of 2013 was around 3.20% to 3.25%. The earning asset yield in the second quarter of 2013 benefited from the full-quarter impact of the investment of approximately $1 billion in excess liquidity earning 25 bps into mortgage-backed securities earning approximately 1.65% in the latter half of the first quarter.

51

The overall cost of funding earning assets was 0.25% in the second quarter of 2013, down 3 bps from the first quarter of 2013 and down 7 bps from the second quarter of 2012. The mix of funding sources was generally stable. Interest-free sources, including noninterest-bearing demand deposits, funded over 30% of earning assets through this period. The overall rate paid on interest-bearing deposits was 0.25% in the current quarter, down slightly from the first quarter of 2013 and 7 bps below the second quarter of 2012. The decreases were primarily due to the impact of the sustained low rate environment on overall deposit rates including the re-pricing of time deposits. The opportunity to re-price time deposits at significantly lower rates over the near term has largely been eliminated.

Net interest income (TE) for the first six months of 2013 totaled $348.6 million, an $11.0 million (3%) decrease from the first half of 2012, primarily due to declining loan and investment yields. Total net purchase-accounting adjustments increased net interest income (TE) for the first half of 2013 by an additional $17.4 million compared to the first six months of 2012. Year-to-date average earning assets were up $306 million (2%) over 2012.

The reported net interest margin for the first six months of 2013 was 4.24% compared to 4.45% in 2012, while the core margin declined to 3.39% in 2013 compared to 3.80% in 2012. Changes in net interest income (TE) and the net interest margin between the year-to-date periods reflected for the most part the same factors that affected the quarterly comparisons.

The following tables detail the components of our net interest income and net interest margin and provide a reconciliation of the Company’s core net interest margin to its reported margin.

Provision for Loan Losses

Hancock recorded a total provision for loan losses for the second quarter of 2013 of $8.3 million, down from $9.6 million in the first quarter of 2013. The provision for non-covered loans was $7.9 million in the second quarter of 2013, compared to $3.0 million in the first quarter of 2013. The increase was related mainly to the net growth in the originated loan portfolio during the second quarter, including the impact of the migration to the originated portfolio of approximately $380 million of loans previously accounted for in the acquired portfolio.

During the second quarter of 2013, the Company recorded a $1.4 million impairment on certain pools of covered loans, with a related increase of $1.0 million in the Company’s FDIC loss share receivable. The net provision from the covered portfolio was $0.4 million in the second quarter of 2013 compared to $6.6 million for the first quarter of 2013. The first quarter provision included approximately $6.5 million of impairment related to changes in the estimated timing of cash flows which does not result in an offsetting impact on the loss share receivable.

The section below on “Allowance for Loan Losses and Asset Quality” provides additional information on changes in the allowance for loans losses and general credit quality. Certain differences in the determination of the allowance for loan losses for originated loans and for acquired performing loans and acquired impaired loans (which includes all covered loans) are described in Note 3 to the consolidated financial statements.

Noninterest Income

Noninterest income totaled $63.9 million for the second quarter of 2013, up $3.7 million (6%) from the first quarter of 2013, and relatively flat compared to second quarter of 2012.

Service charges on deposits totaled $19.9 million for the second quarter of 2013, up $0.8 million compared to the first quarter of 2013, and down $1.0 million from the second quarter of 2012. The linked-quarter increase partly reflects the impact of two additional business days in the second quarter of 2013. Year-to-date, service charge income increased $1.7 million (5%) in 2013 due in part to new and standardized products and services the Company began offering across its footprint in conjunction with the core systems integration in March 2012.

Fees from trust, investment and annuity and insurance fees totaled $19.8 million in the second quarter of 2013, up $2.6 million (15%) linked quarter and $2.7 million (16%) over the second quarter of 2012. In the first six months of 2013, these fee income categories grew $4.3 million (13%) compared to 2012. Improved stock market values and new business were the primary factors contributing to the increases. The linked-quarter fee increase also reflected some seasonality in these lines of business.

Bank card fees and ATM fees totaled $11.4 million in the second quarter of 2013, up $0.3 million (3%) from the first quarter of 2013 due to higher transaction volumes. Compared to the second quarter of 2012, bankcard and ATM fees were down $1.5 million (12%) in the current quarter. Through the first half of 2013, bankcard and ATM fees declined $3.3 million (13%) compared to the first half of 2012. Restrictions on debit card interchange rates arising from the implementation of the Durbin amendment to the Dodd-Frank Act began impacting Whitney Bank in the fourth quarter of 2011 and Hancock Bank at the beginning of the third quarter of 2012. The restrictions reduced Hancock Bank fees by an estimated $2.0 million per quarter. This decline was partially offset by an increase in merchant processing revenue starting in the third quarter of 2012 that was related to the reacquisition of the Company’s merchant business and a change in the terms of the servicing agreement. The reacquisition also added approximately $0.5 million to quarterly expense for the amortization of acquired intangibles.

Fees from secondary mortgage operations in the second quarter of 2013 were down $0.2 million (6%) compared to the first quarter of 2013, and up $1.1 million (37%) from the year-earlier period. Overall, home mortgage origination volumes have benefited as consumers take advantage of historically low rates to refinance or purchase their homes in an improving economic environment. Future production levels will depend on, among other factors, the movement of market interest rates, continued strengthening in the home purchase market, and the level of demand for refinancing.

Other miscellaneous income for the second quarter of 2013 decreased $0.8 million from the second quarter of 2012, and the year-to-date total for 2013 declined $4.0 million. There was no accretion recognized on the FDIC loss share receivable in 2013, compared to $2.0 million recognized in the second quarter of 2012 and $5 million year-to-date in 2012.

Noninterest Expense

Noninterest expense for the second quarter of 2013 totaled $162.3 million, up $2.6 million (2%) from the first quarter of 2013, primarily due to a $2.6 million increase in other real estate expense. The current quarter’s total for noninterest expense was down $5.8 million (3%) from the second quarter of 2012, excluding $11.9 million of merger-related expenses in the earlier period. For the first six months of 2013, total noninterest expense of $321.9 million was down $17.8 million (5%) compared to the first six months of 2012, excluding $45.8 million of merger-related expenses in 2012. The year-over-year decreases are primarily related to cost savings realized as Whitney’s acquired operations were successfully integrated into Hancock, including the impact of branch consolidations and the core systems conversion.

The earlier discussion covering “Highlights of Second Quarter 2013 Financial Results” in the “Overview” section describes the Company’s current expense reduction and efficiency initiative as well as certain actions taken to help achieve targeted reductions in noninterest expense for the first quarter of 2014.

Income Taxes

The effective income tax rate for the second quarter of 2013 was approximately 25% for the second and first quarters of 2013 and 26% for the second quarter of 2012. Management expects the effective tax rate to approximate 26% to 27% in 2013.

The Company’s effective tax rates have varied from the 35% federal statutory rate primarily because of tax-exempt income and the availability of tax credits. Interest income from the financing of state and local governments and earnings from the bank-owned life insurance program are the major components of tax-exempt income. The source of the tax credits for 2013 and 2012 has been investments that generate new market tax credits, low-income housing credits and qualified bond credits.

LIQUIDITY

Liquidity management is focused on ensuring that funds are available to meet the cash flow requirements of our depositors and borrowers, while also meeting the operating, capital and strategic cash flow needs of the Company, the Banks and other subsidiaries. Hancock develops its liquidity management strategies and measures and monitors liquidity risk as part of its overall asset/liability management process.

The asset portion of the balance sheet provides liquidity primarily through loan principal repayments, maturities of investment securities and occasional sales of various assets. Short-term investments such as federal funds sold, securities purchased under agreements to resell and interest-bearing deposits with the Federal Reserve Bank or with other commercial banks are additional sources of liquidity to meet cash flow requirements. As shown in the table below, our ratio of free securities to total securities was 35%, compared to 41% at March 31, 2013 and 27% at December 31, 2012. Free securities represent securities that are not pledged for any purpose, and include unpledged securities assigned to short-term dealer repo agreements or to the Federal Reserve Bank discount window. The decline in the ratio at June 30, 2013 compared to March 31, 2013 was primarily due to the reduction in the investment portfolio to fund loan growth. As discussed later, the Company redeployed approximately $1.0 billion of excess short-term liquidity investments in order from the end of 2012 into the securities portfolio during the latter part of the first quarter of 2013.

Liquidity Metrics

	June 30,			March 31,			December 31,
	2013			2013			2012
Free securities / total securities		35.00	%		41.00	%		27.00	%
Noncore deposits / total deposits		10.07	%		8.47	%		9.20	%
Wholesale funds / core deposits		8.91	%		8.00	%		7.39	%

The liability portion of the balance sheet provides liquidity mainly through various customers’ interest-bearing and noninterest-bearing deposit and sweep accounts. Core deposits consist of total deposits less certificates of deposits of $100,000 or more, brokered deposits, and foreign branch deposits. Toward the end of 2012, Hancock Bank issued $200 million of brokered CDs as a precautionary measure in anticipation of possible deposit outflows associated with the expiration of the FDIC TAG Program at December 31, 2012. Those brokered CDS have matured and $100 million of new brokered three-month CDs were issued in the second quarter as a test of part of the Bank’s liquidity contingency plan. Noncore deposits were 10.07% of total deposits at June 30, 2013 up 160 basis points from March 31, 2013, and up 87 basis points from December 31, 2012. Most of the increase from the first quarter of 2013 resulted from the movement of approximately $200 million of excess funds from DDAs into sweep time deposit products by a few commercial customers. Compared to year-end, the impact of this movement of funds on noncore deposits was partially offset by the $100 million net reduction in brokered CDs.

Purchases of federal funds, securities sold under agreements to repurchase and other short-term borrowings are additional sources of liquidity to meet short-term funding requirements. Wholesale funds, which are comprised of short-term borrowings and long-term debt, were 8.91% of core deposits at June 30, 2013 up 91 bps from March 31, 2013 and 152 bps from December 31, 2012. The increase in this ratio compared to both the prior quarter and year-end is due to both the increase in borrowings under customer repurchase agreements during the first six months of 2013 and the seasonally higher levels of certain core deposit levels at December 31, 2012, as discussed in the section on “Deposits and Short Term Borrowings.” Our short-term borrowing capacity includes an approved line of credit with the Federal Home Loan Bank of $1.7 billion and borrowing capacity at the Federal Reserve’s discount window in excess of $1.0 billion at June 30, 2013. No amounts had been borrowed under these lines at June 30, 2013 or year-end 2012.

Cash generated from operations is another important source of funds to meet liquidity needs. The consolidated statements of cash flows present operating cash flows and summarize all significant sources and uses of funds for the six months ended June 30, 2013 and 2012.

Dividends received from the Banks have been the primary source of funds available to the Company for the payment of dividends to our stockholders and for servicing debt issued by the holding company. The liquidity management process takes into account the various regulatory provisions that can limit the amount of dividends the Banks can distribute to the Company. It is the Company’s policy to maintain assets at the holding company to provide liquidity sufficient to fund five quarters of anticipated stockholder dividends, debt service and operations.

In April, 2013 the Company’s board of directors authorized the repurchase of up to 5% of the Company’s outstanding common stock. The shares may be repurchased through privately negotiated transactions and in the open-market from time to time, depending on market conditions and other factors. The source of funds for the stock buyback program is expected to be upstream dividends from the Banks.

On May 8, 2013 Hancock entered into an accelerated share repurchase (“ASR”) transaction with Morgan Stanley & Co. LLC (“Morgan Stanley”). In the ASR transaction, the Company paid $115 million to Morgan Stanley and received from them approximately 2.8 million shares of Hancock common stock, representing approximately

64

70% of the estimated total number of shares to be repurchased. The actual number of shares to be delivered to the Company in this ASR transaction will be based generally on the volume-weighted average price per share of the Hancock common stock during the term of the ASR agreement less a specified discount and on the amount paid at inception to Morgan Stanley, subject to certain possible adjustments in accordance with the terms of the ASR agreement. Final settlement of the ASR agreement is scheduled to occur no earlier than November, 2013 and no later than May, 2014. The ASR transaction was treated as two separate transactions: (i) the acquisition of treasury shares on the date the shares were received; and (ii) a forward contract indexed to the Company’s common stock that is classified as equity.

CAPITAL RESOURCES

Stockholders’ equity totaled $2.3 billion at June 30, 2013, down $108 million from December 31, 2012. The tangible common equity ratio decreased to 8.52% at June 30, 2013 from 8.72% at December 31, 2012. These declines reflect the $115 million used in May of 2013 to execute the accelerated share repurchase program as discussed in note 6. The primary quantitative measures that regulators use to gauge capital adequacy are the ratios of total and Tier 1 regulatory capital to risk-weighted assets (risk-based capital ratios) and the ratio of Tier 1 capital to average total assets (leverage ratio). Both the Company and its bank subsidiaries are required to maintain minimum risk-based capital ratios of 8.0% total regulatory capital and 4.0% Tier 1 capital. The minimum leverage ratio is 3.0% for bank holding companies and banks that meet certain specified criteria, including having the highest supervisory rating. All others are required to maintain a leverage ratio of at least 4.0%.

On July 2, 2013 the Federal Reserve Board finalized its rule implementing the Basel III regulatory capital framework and related Dodd-Frank Act changes. The interim final rule strengthens the definition of regulatory capital, increases risk-based capital requirements, and makes selected changes to the calculation of risk-weighted assets. The rule sets the Basel III minimum regulatory capital requirements for all organizations. It includes a new common equity Tier 1 ratio of 4.5 percent of risk-weighted assets, raises the minimum Tier 1 capital ratio from 4 percent to 6 percent of risk-weighted assets and would set a new conservation buffer of 2.5 percent of risk-weighted assets. The final rule is effective for the Company on January 1, 2015; however, the rule allows for transition periods for certain changes, including the conservation buffer. Based on estimated capital ratios as of June 30, 2013 using Basel III definitions, the Company and the Banks currently exceed all capital requirements of the new rule, including the fully phased-in conservation buffer.

At June 30, 2013, our regulatory capital ratios and those of the Banks were well in excess of current regulatory minimum requirements, as indicated in the table below. The Company and the Banks have been categorized as “well capitalized” in the most recent notices received from our regulators. Regulatory capital ratios for the Company and the Banks declined from December 31, 2012 to June 30, 2013 primarily due to execution of the $115 million accelerated share repurchase plan by the Company and dividends paid by the Banks to the parent to facilitate the repurchase. Completion of the stock repurchase plan is not expected to have a significant impact on the capital ratios of the Company or the Banks.

(1) Tier 1 capital generally includes common equity, retained earnings, non-controlling interest in equity of consolidated subsidiaries and a limited amount of qualifying perpetual preferred stock, reduced by goodwill and other disallowed intangibles and disallowed deferred tax assets and certain other assets. Total capital consists of Tier 1 capital plus perpetual preferred stock not qualifying as Tier 1 capital, mandatory convertible securities, certain types of subordinated debt and a limited amount of allowances for credit losses.

(2) The risk-weighted asset base is equal to the sum of the aggregate value of assets and credit-converted off-balance sheet items in each risk category as specified in regulatory guidelines, multiplied by the weight assigned by the guidelines to that category.

(3) The Tier 1 leverage capital ratio is Tier 1 capital divided by average total assets reduced by the deductions for Tier 1 capital noted above.

BALANCE SHEET ANALYSIS

Securities

Investment in securities totaled $4.3 billion at June 30, 2013, down $358 million from the end of March 2013, but up $545 million from December 31, 2012. During the second quarter of 2013, funds from repayments and maturities in the securities portfolio were used primarily to support loan growth. Toward the latter part of the first quarter of 2013, management had redeployed approximately $1.0 billion of excess liquidity to the investment portfolio. This excess liquidity had been accumulated as a precautionary measure against possible deposit outflows in early 2013 upon expiration of the FDIC Transaction Account Guarantee (TAG) Program which provided for unlimited deposit insurance on noninterest-bearing transaction accounts. The Banks did not experience any material deposit outflows as a result of the TAG Program’s expiration.

At June 30, 2013 securities available for sale totaled $2.6 billion and securities held to maturity totaled $1.7 billion. These balances compare to December 31, 2012 totals of $2.0 billion and $1.7 billion, respectively. Our securities portfolio consists mainly of residential mortgage-backed securities and collateralized mortgage obligations issued or guaranteed by U.S. government agencies. The portfolio is designed to enhance liquidity

66

while providing an acceptable rate of return. We invest only in high quality securities of investment grade quality with a targeted duration, for the overall portfolio, generally between two to five. At June 30, 2013, the average maturity of the portfolio was 3.35 years with an effective duration of 3.87 and a weighted-average yield of 2.23%. The effective duration increases to 4.30 with a 100 basis point increase in the yield curve and to 4.60 with a 200 basis point increase. At year end, the average maturity of the portfolio was 3.16 years with an effective duration of 2.19 and a weighted-average yield of 2.71%. The changes in these metrics from December 31, 2012 reflect the redeployment of excess liquidity into the securities portfolio.

Loans

Total loans at June 30, 2013 were $11.7 billion, up $199 million (2%) compared to March 31, 2013 and up $104 million (1%) from December 31, 2012. Excluding the FDIC-covered portfolio, total loans increased $245 million (2%) from March 31, 2013 and $189 million compared to year-end 2012. The noncovered loan portfolio was up $760 million (7%) from a year ago.

See Note 3 to the consolidated financial statements for the composition of originated, acquired and covered loans at June 30, 2013 and December 31, 2012. Originated loans include all loans not included in the acquired and covered loan portfolios described as follows. Acquired loans are those purchased in the Whitney acquisition on June 4, 2011 and that continue to be subject to purchase accounting considerations. Acquired loans include those that were performing satisfactorily at the acquisition date (acquired performing) and loans acquired with evidence of credit deterioration (acquired impaired). Covered loans are those purchased in the December 2009 acquisition of Peoples First, which are covered by loss share agreements between the FDIC and the Company that afford significant loss protection. Purchased loans acquired in a business combination are recorded at estimated fair value on their purchase date without carryover of any allowance for loan losses. Certain differences in the accounting for originated loans and for acquired performing and acquired impaired loans (which include all covered loans) are described in Note 3 to the consolidated financial statements.

Considered together, originated and acquired commercial non-real estate (C&I) loans were up a net $223 million since year-end 2012, with most of the growth in the second quarter of 2013. New C&I loan activity was solid across many markets in the Company’s footprint during the first six months of 2013, with the largest contributions from the Texas, Louisiana and Florida markets.

The Company’s commercial customer base is diversified over a range of industries, including oil and gas (O&G), wholesale and retail trade in various durable and nondurable products and the manufacture of such products, marine transportation and maritime construction, financial and professional services, and agricultural production. Loans outstanding to O&G industry customers totaled approximately $1.0 billion at June 30, 2013, up approximately $100 million from December 31, 2012. The majority of the O&G portfolio is with customers providing transportation and other services and products to support exploration and production activities. The Banks lend mainly to middle-market and smaller commercial entities, although they do participate in larger shared-credit loan facilities with familiar businesses operating in the Company’s market areas. Shared credits funded at June 30, 2013 totaled approximately $1.3 billion, up approximately $100 million from the last quarter and $200 million from December 31, 2012. Approximately $640 million of shared national credits were with O&G customers at June 30, 2013, up $40 million from March 31, 2013, and up $150 million from year-end.

Construction and land development loans (C&D) loans and commercial real estate (CRE) loans in the originated and acquired portfolios decreased a net $49 million over the first six months of 2013. CRE loans include loans on both income-producing properties as well as properties used by borrowers in commercial operations. The largest component of new lending activity during 2013 has been on properties used by smaller C&I customers. Overall, opportunities for funding new quality projects in the current environment, while improving, remain limited.

Residential mortgages in the originated and acquired portfolios were up a net $45 million during the second quarter and $66 million over the first six months of 2013, reflecting in part an increased emphasis on portfolio lending with certain market segments. Consumer loans decreased by a net $52 million over this period.

67

Total covered loans at June 30, 2013 were down $46 million from March 31, 2013 and $85 million from December 31, 2012, reflecting normal repayments, charge-offs and foreclosures. The covered portfolio will continue to decline over the terms of the loss share agreements.

Allowance for Loan Losses and Asset Quality

The Company’s total allowance for loan losses was $138.0 million at June 30, 2013, compared to $137.8 million at March 31, 2013. The ratio of the allowance to period-end loans was 1.18% at June 30, 2013, down slightly from 1.20% at March 31, 2013. The allowance maintained on the originated portion of the loan portfolio totaled $76.4 million, or 0.93% of related loans, at June 30, 2013, as compared to $75.5 million, or 1.02%, at March 31, 2013. During the second quarter of 2013, in order to better refine the process and reflect the activity in the Bank’s loan portfolios at a more granular level, management revised the estimation process for evaluating the adequacy of the general reserve component of the allowance for loan losses for the originated and acquired performing loan portfolios. There were no changes in the methodology for the specific reserve analysis on loans considered to be impaired or acquired credit-impaired loans. The change in the methodology, which is described Note 1 to the consolidated financial statements included elsewhere in this report, was implemented as of April 1, 2013 and resulted in no change in the total amount of allowance for loan losses.

The Company recorded a total provision for loan losses for the second quarter of 2013 of $8.3 million, down from $9.6 million in the first quarter of 2013. The increase in the provision for non-covered loans to $7.9 million in the second quarter of 2013, compared to $3.0 million in the first quarter of 2013, was related mainly to the net growth in the originated loan portfolio during the second quarter. $380 million of loans previously accounted for in the acquired portfolio migrated to the originated portfolio. These were mainly revolving credit relationships with C&I customers that had renewed beyond their maturity dates.

During the second quarter of 2013, the Company recorded $1.4 million of impairment on certain pools of covered loans, with a related increase of $1.0 million in the Company’s FDIC loss share receivable. The net provision from the covered portfolio was $0.4 million in the second quarter of 2013 compared to $6.6 million for the first quarter of 2013. The first quarter provision included approximately $6.5 million of impairment related to changes in the estimated timing of cash flows which does not result in an offsetting impact on the loss share receivable.

Net charge-offs from the non-covered loan portfolio were $7.0 million, or 0.24% of average total loans on an annualized basis in the second quarter of 2013 compared to $6.6 million, or 0.23% of average total loans in the first quarter of 2013.

In the following tables, certain disaggregated information was not available for the commercial non-real estate, construction and land development and commercial real estate loans categories for 2012. In these instances, combined information for these categories is provided under the caption “commercial loans.”

Nonperforming assets (NPAs), which exclude loans that were credit impaired at the time of the Whitney and Peoples First acquisitions, totaled $216 million at June 30, 2013, down $13 million from March 31, 2013 and $40 million from December 31, 2012. Nonperforming assets as a percent of total loans, ORE, and other foreclosed assets was 1.84% at June 30, 2013, compared to 1.98% at March 31, 2013 and 2.19% at December 31, 2012. The decrease in overall NPAs in the first half of 2013 reflects a net reduction of $30 million in ORE properties and a $10 million reduction in nonperforming loans. Future levels of ORE may be volatile in the near term due to ongoing activity related to the covered portfolio and the anticipated closings of certain bank locations in connection with the Company’s overall efficiency initiative.

Short-Term Investments

Short-term liquidity investments, including interest-bearing bank deposits and Federal funds sold, declined $1.1 billion from December 31, 2012 to a total of $443 million at June 30, 2013. Average short-term investments for the second quarter of 2013 were down $605 million (57%) compared to the first quarter of 2013. As discussed earlier in the section on “Securities,” during the latter part of the first quarter of 2013, management redeployed the excess short-term investments it had accumulated toward the end of 2012 in anticipation of possible increased demands on liquidity from the expiration of the TAG Program.

71

Deposits

Total deposits were $15.2 billion at June 30, 2013, down less than 1% from March 31, 2013, and down $588 million (4%) from December 31, 2012. Average deposits for the second quarter of 2013 were also down less than 1% from the first quarter of 2013.

Noninterest-bearing demand deposits (DDAs) declined by $78 million (1%) during the second quarter to $5.3 billion at June 30, 2013, and were down $239 million (5%) from December 31, 2012. These decreases reflected mainly the movement of some excess funds from DDAs to sweep time deposit products by a few commercial customers and some normal year-end seaonality in the DDa deposit base. DDAs at the end of the second quarter of 2013 were up almost $300 million (6%) from a year earlier. Noninterest-bearing demand deposits comprised 35% of total period-end deposits at June 30, 2013 compared to 36% at both March 31, 2013 and year-end 2012 and 34% at June 30, 2012. Interest-bearing public fund deposits totaled $1.4 billion at June 30, 2013, down $118 million from March 31, 2013 and $169 million (11%) from year-end 2012. Public fund entities typically carry higher balances at year end, with subsequent reduction throughout the first half of the year.

Time deposits totaled $2.4 billion at June 30, 2013, up $151 million from March 31, 2013 but down $62 million from year-end 2012. Balances in sweep time deposit products increased $258 million from the end of 2012, almost entirely during the second quarter. This increase was due primarily to the movement of funds from DDAs by some commercial customers, as mentioned earlier. Certificates of deposits (CDs) were down $321 million (14%) compared to December 31, 2012, partially due to a net $100 million reduction in brokered CDs. Low yields available to customers on CD maturities continue to drive reductions in CD balances.

Short-Term Borrowings

At June 30, 2013, short-term borrowings totaled $828 million, up $189 million (30%) from December 31, 2012. Short-term borrowings totaled $833 million at June 30, 2012. Securities sold under agreements to repurchase are the main source of short-term borrowings. These agreements are offered mainly to commercial customers to assist them with their cash management strategies or to provide a temporary investment vehicle for their excess liquidity pending redeployment for corporate or investment purposes. While customer repurchase agreements provide a recurring source of funds to the Banks, the amounts available over time can be volatile. Customer repos are $677 million at the end of the current quarter, compared to $571 million at March 31, 2013 and $833 million at June 30, 2012.

OFF-BALANCE SHEET ARRANGEMENTS

Loan Commitments and Letters of Credit

In the normal course of business, the Banks enter into financial instruments, such as commitments to extend credit and letters of credit, to meet the financing needs of their customers. Such instruments are not reflected in the accompanying consolidated financial statements until they are funded, although they expose the Banks to varying degrees of credit risk and interest rate risk in much the same way as funded loans.

Commitments to extend credit include revolving commercial credit lines, nonrevolving loan commitments issued mainly to finance the acquisition and development or construction of real property or equipment, and credit card and personal credit lines. The availability of funds under commercial credit lines and loan commitments generally depends on whether the borrower continues to meet credit standards established in the underlying contract and has not violated other contractual conditions. Loan commitments generally have fixed

72

expiration dates or other termination clauses and may require payment of a fee by the borrower. Credit card and personal credit lines are generally subject to cancellation if the borrower’s credit quality deteriorates. A number of commercial and personal credit lines are used only partially or, in some cases, not at all before they expire, and the total commitment amounts do not necessarily represent future cash requirements of the Company.

A substantial majority of the letters of credit are standby agreements that obligate the Banks to fulfill a customer’s financial commitments to a third party if the customer is unable to perform. The Banks issue standby letters of credit primarily to provide credit enhancement to their customers’ other commercial or public financing arrangements and to help them demonstrate financial capacity to vendors of essential goods and services.

The contract amounts of these instruments reflect the Company’s exposure to credit risk. The Company undertakes the same credit evaluation in making loan commitments and assuming conditional obligations as it does for on-balance sheet instruments and may require collateral or other credit support.

The following table shows the commitments to extend credit and letters of credit at June 30, 2013 according to expiration date.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

The consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America and with general practices followed by the banking industry which requires management to make estimates and assumptions about future events. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities not readily apparent from other sources. Actual results could differ significantly from those estimates.

During the second quarter of 2013, in order to better refine the process and reflect the activity in the Banks’ loan portfolios at a more granular level, management revised the estimation process for evaluating the adequacy of the general reserve component of the allowance for loan losses for the originated portfolio. The change in the methodology, which is described in Note 1 to the consolidated financial statements included elsewhere in this report, was implemented as of April 1, 2013 and resulted in no change in the total amount of allowance for loan losses.

SEGMENT REPORTING

Note 12 to the consolidated financial statements provides information about the Company’s reportable operating segments and presents comparative financial information for these operating segments for the three month and six month periods ended June 31, 2013 and June 31, 2012.

Net income in the second quarter of 2013 for the Hancock segment totaled approximately $18.4 million, up $6.1 million from the same period in 2012. Net interest income declined $4.8 million mainly due to reduced earning asset yields. Noninterest expense decreased $4.4 million, excluding $4.5 million in merger-related expenses from the second quarter of 2012 mainly due to movement of allocated overhead expenses between the Banks.

Net income for the Whitney segment in the second quarter of 2013 totaled approximately $28.4 million, up $2.4 million from the same period in 2012. Excluding tax-effected merger-related expenses in the prior year period, net income for the Whitney segment is down $2.5 million from the second quarter of 2012. Net interest income declined $3.5 million between these periods also due to reduced earning asset yields. Noninterest expense decreased $2.7 million, excluding $7.4 million of merger-related expenses from the second quarter of 2012 mainly due to synergies realized from successful integration of operations with Hancock, including the impact of branch consolidations and the core systems conversion.

FORWARD LOOKING STATEMENTS

This Form 10-Q contains “forward-looking statements” within the meaning of section 27A of the Securities Act of 1933, as amended, and section 21E of the Securities Exchange Act of 1934, as amended, and we intend such forward-looking statements to be covered by the safe harbor provisions therein and are including this statement for purposes of invoking these safe-harbor provisions. Forward-looking statements provide projections of results of operations or of financial condition or state other forward-looking information, such as expectations about future conditions and descriptions of plans and strategies for the future. Forward-looking statements that we may make include, but may not be limited to, comments with respect to loan growth, deposit trends, credit quality trends, net interest margin trends, future expense levels (including merger costs and cost synergies), projected tax rates, economic conditions in our markets, future profitability, purchase accounting impacts such as accretion levels, and the financial impact of regulatory requirements such as the Durbin amendment. Hancock’s ability to accurately project results or predict the effects of future plans or strategies is inherently limited. Although Hancock believes that the expectations reflected in its forward-looking statements are based on reasonable assumptions, actual results and performance could differ materially from those set forth in the forward-looking statements. Factors that could cause actual results to differ from those expressed in Hancock’s forward-looking statements include, but are not limited to, those risk factors outlined in Hancock’s public filings with the Securities and Exchange Commission, which are available at the SEC’s internet site (http://www.sec.gov). You are cautioned not to place undue reliance on these forward-looking statements. Hancock does not intend, and undertakes no obligation, to update or revise any forward-looking statements, whether as a result of differences in actual results, changes in assumptions or changes in other factors affecting such statements, except as required by law.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Our net income is materially dependent on our net interest income. Hancock’s primary market risk is interest rate risk that stems from uncertainty with respect to absolute and relative levels of future market interest rates that affect our financial products and services. In an attempt to manage our exposure to interest rate risk, management measures the sensitivity of our net interest income and cash flows under various market interest rate scenarios, establishes interest rate risk management policies and implements asset/liability management strategies designed to produce a relatively stable net interest margin under varying rate environments.

74

Hancock measures its interest rate sensitivity primarily by running net interest income simulations. The model measures annual net interest income sensitivity relative to a base case scenario and incorporates assumptions regarding balance sheet growth and the mix of earning assets and funding sources as well as pricing, re-pricing and maturity characteristics of the existing and projected balance sheet. The table below presents the results of simulations run as of June 30, 2013, assuming the indicated instantaneous and sustained parallel shift in the yield curve at the measurement date. These results indicate that we are slightly asset sensitive as compared to the stable rate environment assumed for the base case.

Net Interest Income (te) at Risk
Change in interest rate (basis point)		Estimated increase  (decrease) in net interest income
	Stable		0.00	%
	+100		1.70	%
	+200		4.52	%
	+300		7.66	%

Note: Decrease in interest rates discontinued in the current rate environment

The foregoing disclosures related to our market risk should be read in conjunction with our audited consolidated financial statements, related notes and management’s discussion and analysis for the year ended December 31, 2012 included in our 2012 Annual Report on Form 10-K.

Item 4. Controls and Procedures

At the end of the period covered by this Quarterly Report on Form 10-Q, we carried out an evaluation, under the supervision and with the participation of management, including the Chief Executive Officers and the Chief Financial Officer, of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15 (e) and 15d-15 (e) under the Exchange Act). Based upon that evaluation, our Chief Executive Officers and Chief Financial Officer have concluded that our disclosure controls and procedures are effective as of the end of the period covered by this report to timely alert them to material information relating to us (including our consolidated subsidiaries) required to be included in our Exchange Act filings.

Our management, including the Chief Executive Officers and Chief Financial Officer, identified no change in our internal control over financial reporting that occurred during the three month period ended June 30, 2013, that has materially affected, or is reasonably likely to materially affect, our internal controls over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

We and our subsidiaries are party to various legal proceedings arising in the ordinary course of business. We do not believe that loss contingencies, if any, arising from pending litigation and regulatory matters will have a material adverse effect on our consolidated financial position or liquidity.

75

Item 1A. Risk Factors

There have been no material changes from the risk factors previously disclosed in our Form 10-K for the year ended December 31, 2012. The risks described may not be the only risks facing us. Additional risks and uncertainties not currently known to us or that are currently considered to not be material also may materially adversely affect our business, financial condition, and/or operating results.

Compensation And Retirement Disclosure [Abstract]

Retirement Plans

9. Retirement Plans

Effective January 1, 2013, the Company adopted one qualified defined benefit pension plan covering all eligible employees. Eligibility is based on minimum age and service-related requirements as well as job classification. The consolidated plan replaced the separate qualified plans covering legacy Hancock employees (Hancock Plan) and legacy Whitney employees (Whitney Plan). The new qualified plan terms are substantially the same for legacy Hancock employees as those in effect at December 31, 2012 under the Hancock Plan. Retirement benefits for eligible legacy Whitney employees under the new plan will be based on the employee’s accrued benefit under the Whitney Plan as of December 31, 2012 plus any benefit accrued under the new plan based on years of service and compensation beginning in 2013. The Whitney Plan had been closed to new participants since 2008, and benefit accruals had been frozen for all participants other than those meeting certain vesting, age and years of service criteria as of December 31, 2008. Accrued benefits under the nonqualified plan covering certain legacy Whitney employees were frozen as of December 31, 2012 and no future benefits will be accrued under this plan.

The Company also sponsors defined benefit postretirement plans for both legacy Hancock and legacy Whitney employees that provide health care and life insurance benefits. Benefits under the Hancock plan are not available to employees hired on or after January 1, 2000. Benefits under the Whitney plan are restricted to retirees who were already receiving benefits at the time of plan amendments in 2007 or active participants who were eligible to receive benefits as of December 31, 2007.

The following table shows the components of net periodic benefits cost included in expense for the plans.

	Three Months Ended June 30,

Net periodic benefit cost	$	5,486		$	5,689		$	1,631	$	1,147

The Company anticipates a total contribution to the pension plan of $10 million for 2013.

Effective January 1, 2013, the Company also combined the Hancock and Whitney defined contribution retirement benefit plans (401(k) plans). Under the combined plan, the Company matches 100% of the first 1% of compensation saved by a participant, and 50% of the next 5% of compensation saved. Under the prior Hancock 401(k) plan, the Company matched 50% of a participant’s savings up to 6% of compensation, while under the prior Whitney 401(k) plan, the Company matched 100% of a participant’s savings up to 4% of compensation. The Company could also make a discretionary profit sharing contribution under the Whitney plan on behalf of participants who were either ineligible to participate in the Whitney qualified defined-benefit pension plan or subject to the freeze in benefit accruals under that plan. With the adoption of the new qualified pension plan discussed above and the combined 401(k) plan, the discretionary profit-sharing contribution is no longer available for plan years beginning in 2013.

Substantially all of the unrealized losses relate to changes in market rates on fixed-rate debt securities since the respective purchase dates. In all cases, the indicated impairment would be recovered no later than 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 obligor’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 full recovery of the indicated impairment. Accordingly, the unrealized losses on these securities have been determined to be temporary.

Securities with carrying values totaling $2.8 billion at June 30, 2013 and $2.6 billion at December 31, 2012 were pledged primarily to secure public deposits or securities sold under agreements to repurchase.

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 are computed in a manner that approximates a level yield on recorded principal. Interest on loans is recorded as income as earned. The accrual of interest on an originated loan is discontinued when it is probable that the borrower will not be able to meet payment obligations as they become due. The Company maintains an allowance for loan losses on originated loans that represents management’s estimate of probable losses incurred in this portfolio category. The methodology for estimating the allowance is described in Note 1 to the Company’s Annual Report on Form 10-K for the year ended December 31, 2012. See Note 1 elsewhere in this document for updates to the allowance methodology for originated and acquired performing loans. As actual losses are incurred, they are charged against the allowance. Subsequent recoveries are added back to the allowance when collected.

Acquired loans

Acquired loans are those 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”), and then further segregated into loan pools designed to facilitate the development of expected cash flows. The factors considered in segregating the acquired portfolio are detailed in Note 1 to the Company’s Annual Report on Form 10-K for the year ended December 31, 2012. The fair value estimate for each pool of acquired performing and acquired impaired loans was based on the estimate of expected cash flows, both principal and interest, from that pool, discounted at prevailing market interest rates.

The difference between the fair value of an acquired performing loan pool and the contractual amounts due at the acquisition date (the “fair value discount”) is accreted into income over the estimated life of the pool. Management estimates an allowance for loan losses for acquired performing loans using a methodology similar to that used for originated loans. The allowance determined for each loan pool is compared to the remaining fair value discount for that pool. If the allowance is greater, the excess is added to the reported allowance through a provision for loan losses. If the allowance is less, no additional allowance or provision is recognized. Actual losses first reduce any remaining fair value discount for the loan pool. Once the discount is fully depleted, losses are applied against the allowance established for that pool. Acquired performing loans are placed on nonaccrual status and considered and reported as nonperforming or past due using the same criteria applied to the originated portfolio.

The excess of cash flows expected to be collected from an acquired impaired loan pool over the pool’s estimated fair value at acquisition is referred to as the accretable yield and is recognized in interest income using an effective yield method over the remaining life of the 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, an 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 that afford the Company significant loss protection. These covered loans are accounted for as acquired impaired loans as described above. The loss share receivable is measured separately from the related covered loans as it is not contractually embedded in the loans and is not transferable should the loans be sold. The fair value of the loss share receivable at acquisition was estimated by discounting projected cash flows related to the loss share agreements based on the expected reimbursements for losses using the applicable loss share percentages, including appropriate consideration of possible true-up payments to the FDIC at the expiration of the agreements. The discounted amount is accreted into non-interest income over the remaining life of the covered loan pool or the life of the loss share agreement.

The loss share receivable is reviewed and updated prospectively as loss estimates related to the covered loans change. Increases in expected reimbursements under the loss sharing agreements from a covered loan pool 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 can result in reductions in or additions to the provision for loan losses, which serve to offset the impact on the provision from impairment recognized on the underlying covered loan pool and reversals of previously recognized impairment. 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.

(b) In accordance with purchase accounting rules, the Whitney loans were recorded at their fair value at the time of the acquisition, and the prior allowance for loan losses was eliminated. No allowance had been established on these acquired loans since the acquisition date through June 30, 2012. These loans are included in the ending balance of loans collectively evaluated for impairment.

The following tables show the composition of nonaccrual loans by portfolio segment and class. Acquired impaired and certain covered loans are considered to be performing due to the application of the accretion method and are excluded from the table. Covered loans accounted for using the cost recovery method do not have an accretable yield and are disclosed below as nonaccrual loans. Acquired performing loans that have subsequently been placed on nonaccrual status are also disclosed below.

The amount of interest that would have been recorded on nonaccrual loans and taken into income for the six months ended June 30, 2013 was approximately $3.7 million. Interest actually received on nonaccrual loans during the six months ended June 30, 2013 was $2.1 million.

Included in nonaccrual loans at June 30, 2013 is $20.6 million in restructured commercial loans. Total troubled debt restructurings (TDRs) were $33.7 million as of June 30, 2013 and $32.2 million at December 31, 2012. Acquired and covered impaired loans modified post-acquisition are not removed from their accounting pool and accounted for as TDRs, even if those loans would otherwise be deemed TDRs.

The table below details TDRs that occurred during the six months ended June 30, 2013 and June 30, 2012 by portfolio segment (dollar amounts in thousands). During these periods, no loan modified as a TDR defaulted within twelve months of its modification date. All troubled debt restructurings are rated substandard and are considered impaired in calculating the allowance for loan losses.

Loan review uses a risk-focused continuous monitoring program that provides for an independent, objective and timely review of credit risk within the company. Below are the definitions of the Company’s internally assigned grades:

Commercial:

• Pass - loans properly approved, documented, collateralized, and performing which do not reflect an abnormal credit risk.

• Pass - Watch - Credits in this category are of sufficient risk to cause concern. This category is reserved for credits that display negative performance trends. The “Watch” grade should be regarded as a transition category.

• Special Mention - These credits exhibit some signs of “Watch,” but to a greater magnitude. These credits constitute an undue and unwarranted credit risk, but not to a point of justifying a classification of “Substandard.” They have weaknesses that, if not checked or corrected, weaken the asset or inadequately protect the bank.

• Substandard - These credits constitute an unacceptable risk to the bank. They have recognized credit weaknesses that jeopardize the repayment of the debt. Repayment sources are marginal or unclear.

• Doubtful - A Doubtful credit has all of the weaknesses inherent in one classified “Substandard” with the added characteristic that weaknesses make collection in full highly questionable or improbable.

• Loss - Credits classified as Loss are considered uncollectable and are charged off promptly once so classified.

Consumer:

• Performing – Loans on which payments of principal and interest are less than 90 days past due.

• Nonperforming – Loans on which payments of principal and interest are more than 90 days past due and on nonaccrual status.

Accounting Policies [Abstract]

Basis of Presentation

1. Basis of Presentation

The consolidated financial statements include the accounts of Hancock Holding Company and all other entities in which it has a controlling interest (the “Company”). The financial statements include all adjustments that are, in the opinion of management, necessary to present fairly the Company’s financial condition, results of operations, changes in stockholders’ equity and cash flows for the interim periods presented. Some financial information and disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the U.S. (U.S. GAAP) have been condensed or omitted in this Form 10-Q pursuant to Securities and Exchange Commission rules and regulations. These financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto included in the Company’s 2012 Annual Report on Form 10-K. Financial information reported in these financial statements is not necessarily indicative of the Company’s financial condition, results of operations, or cash flows for any other interim or annual period.

Use of Estimates

The accounting principles the Company follows and the methods for applying these principles conform with U.S. GAAP and with 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

Allowance for Loan Losses

The allowance for loan and lease losses (“ALLL”) is a valuation account available to absorb losses on loans. The ALLL is established and maintained at an amount sufficient to cover the estimated credit losses associated with the loan and lease portfolios of the Company as of the date of the determination. Credit losses arise not only from credit risk, but also from other risks inherent in the lending process including, but not limited to, collateral risk, operational risk, concentration risk, and economic risk. As such, all related risks of lending are considered when assessing the adequacy of the allowance for loan and lease losses. Quarterly, management estimates the inherent losses in the existing loan portfolio based on a number of factors, including the Company’s past loan loss and delinquency experience, known and inherent risks in the portfolio, adverse situations that may affect the borrowers’ ability to repay, the estimated value of any underlying collateral and current economic conditions.

The analysis and methodology for estimating the ALLL include two primary elements. These elements are a loss-rate analysis of various loan groups which incorporates a historical loss rate as updated for current conditions and a specific reserve analysis for those loans considered impaired.

During the second quarter of 2013, management revised the methodology for the loss-rate analysis for the originated and acquired performing loan portfolios due to the increased size and complexity of the Company’s commercial loan portfolio. The primary changes in the methodology were to segment loans with similar risk characteristics at a more granular level and to lengthen the period used for analyzing loss emergence and estimating loss factors. The changes were implemented as of April 1, 2013 and resulted in no material change in the total amount of the allowance for loan losses. Management made the following principal changes to the methodology during the second quarter of 2013:

• Established a more granular stratification of the major loan segments to enhance the homogeneity of the loan classes. Previously, the Company segmented loans into three primary groups—commercial, residential mortgage and consumer—for the loss-rate analysis. The revised loan segments are commercial non-real estate, construction and land development, commercial real estate, residential mortgage and consumer. Both quantitative and qualitative factors are applied at the more detailed portfolio segmentation.

• Included portfolio risk ratings in loss-rate analysis. For loss-rate analysis, commercial loans (commercial non-real estate, construction and land development and commercial real estate) are further subdivided by risk rating, and retail loans (residential mortgage and consumer) are further subdivided by delinquency. Previously, the methodology indirectly incorporated risk ratings and delinquencies.

• Lengthened the loss emergence period. The Company uses an eighteen month loss emergence period for commercial loans and a twelve month loss emergence period for retail loans. Historical loss rates are calculated for each commercial segment using a weighted average of three eighteen-month periods over a fourteen quarter look-back period, and for each retail segment using a weighted average of three twelve-month periods over a twelve quarter look-back period. Previously, historical loss rates were calculated using an average of three twelve month loss emergence periods over a three year look back period for all loan segments. As circumstances dictate, management will make adjustments to the loss history to reflect differences in current conditions as compared to those during the historical loss period. Conditions to be considered include problem loan trends, current business and economic conditions, credit concentrations, lending policies and procedures, lending staff, collateral values, loan profiles and volumes, loan review quality, and changes in competition and regulations.

There were no changes in the methodology for the specific reserve analysis on loans considered to be impaired or acquired credit-impaired loans during the quarter ended June 30, 2013.

There were no other material changes or developments with respect to methodologies that the Company uses when applying what management believes are critical accounting policies and developing critical accounting estimates as disclosed in our Form 10-K for the year ended December 31, 2012.

Equity [Abstract]

Stockholders' Equity

6. Stockholders’ Equity

Stock Repurchase Program

The Company’s board of directors approved a stock repurchase program on April 30, 2013 that authorizes the repurchase of up to 5% of the Company’s outstanding common stock.

On May 8, 2013 Hancock entered into an accelerated share repurchase (“ASR”) transaction with Morgan Stanley & Co. LLC (“Morgan Stanley”). In the ASR transaction, the Company paid $115 million to Morgan Stanley and received from them approximately 2.8 million shares of Hancock common stock, representing approximately 70% of the estimated total number of shares to be repurchased. The actual number of shares to be delivered to the Company in this ASR transaction will be based generally on the volume-weighted average price per share of the Hancock common stock during the term of the ASR agreement less a specified discount and on the amount paid at inception to Morgan Stanley, subject to certain possible adjustments in accordance with the terms of the ASR agreement. Final settlement of the ASR agreement is scheduled to occur no earlier than November, 2013 and no later than May, 2014. The ASR transaction was treated as two separate transactions: (i) the acquisition of treasury shares on the date the shares were received; and (ii) a forward contract indexed to the Company’s common stock that is classified as equity.

Accumulated Other Comprehensive Income (Loss)

Accumulated other comprehensive income (loss) (AOCI) is reported as a component of stockholders’ equity. AOCI can include, among other items, unrealized holding gains and losses on securities available for sale (AFS), gains and losses associated with pension or other post retirement benefits that are not recognized immediately as a component of net periodic benefit cost, and gains and losses on derivative instruments that are designated as, and qualify as, cash flow hedges. The net unrealized gain on AFS securities reclassified as securities held to maturity (HTM) during 2012 also continues to be reported as a component of AOCI and will be amortized over the estimated remaining life of the securities as an adjustment to interest income. The components of AOCI are reported net of related tax effects. The components of AOCI and changes in those components are presented in the following table (in thousands).

Derivative Instruments And Hedging Activities Disclosure [Abstract]

Derivatives

5. Derivatives

Risk Management Objective of Using Derivatives

The Company enters into derivative financial instruments to manage risks related to differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments, currently related to our variable rate borrowing. The Banks have also entered into interest rate derivative agreements as a service to certain qualifying customers. The Banks manage a matched book with respect to these customer derivatives in order to minimize the net risk exposure resulting from such agreements. The Banks also enter into risk participation agreements under which they may either sell or buy credit risk associated with a customer’s performance under certain interest rate derivative contracts related to loans in which participation interests have been sold to or purchased from other banks.

Fair Values of Derivative Instruments on the Balance Sheet

The table below presents the notional amounts and fair values (in thousands) of the Company’s derivative financial instruments as well as their classification on the consolidated balance sheets as of June 30, 2013 and December 31, 2012.

The Company had been party to an interest rate swap agreement with a notional amount of $140 million under which the Company received interest at a variable rate and paid at a fixed rate. This derivative instrument represented by this swap agreement was designated as and qualified as a cash flow hedge of the Company’s forecasted variable cash flows under a variable-rate term borrowing agreement. The swap agreement expired in June 2013.

During the term of the swap agreement, the effective portion of changes in the fair value of the derivative instrument was recorded in accumulated other comprehensive income (“AOCI”) and subsequently reclassified into earnings in the periods that the hedged forecasted variable-rate interest payments affected earnings. The impact on AOCI was insignificant during 2013 and 2012. There was no ineffective portion of the change in fair value of the derivative recognized directly in earnings.

Derivatives Not Designated as Hedges

Customer interest rate derivatives

The Banks enter into interest rate derivative agreements, primarily rate swaps, with commercial banking customers to facilitate their risk management strategies. The Banks simultaneously enter into offsetting agreements with unrelated financial institutions, thereby mitigating its net risk exposure resulting from such transactions. Because the interest rate derivatives associated with this program do not meet hedge accounting requirements, changes in the fair value of both the customer derivatives and the offsetting derivatives are recognized directly in earnings.

Risk participation agreements

The Banks also enter into risk participation agreements under which they may either assume or sell credit risk associated with a borrower’s performance under certain interest rate derivative contracts. In those instances where the Banks have assumed credit risk, they are not a direct counterparty to the derivative contract with the borrower and have entered into the risk participation agreement because they are a party to the related loan agreement with the borrower. In those instances in which the Banks have sold credit risk, they are the sole counterparty to the derivative contract with the borrower and have entered into the risk participation agreement because other banks participate in the related loan agreement. The Banks manage their credit risk under risk participation agreements by monitoring the creditworthiness of the borrower, based on their normal credit review process.

Mortgage banking derivatives

The Banks also enter into certain derivative agreements as part of their mortgage banking activities. These agreements include interest rate lock commitments on prospective residential mortgage loans and forward commitments to sell these loans to investors on a best efforts delivery basis.

Effect of Derivative Instruments on the Income Statement

The effect of the Company’s derivative financial instruments on the income statement was immaterial for the three month and six month periods ended June 30, 2013 and 2012.

Credit-risk-related Contingent Features

Certain of the Banks’ derivative instruments contain provisions allowing the financial institution counterparty to terminate the contracts in certain circumstances, such as the downgrade of the Banks’ credit ratings below specified levels, a default by the Bank on its indebtedness, or the failure of a Bank to maintain specified minimum regulatory capital ratios or its regulatory status as a well-capitalized institution. These derivative agreements also contain provisions regarding the posting of collateral by each party. As of June 30, 2013, the aggregate fair value of derivative instruments with credit-risk-related contingent features that were in a net liability position was $8.7 million, for which the Banks had posted collateral of $6.2 million.

Share-Based Payment Arrangements

8. Share-Based Payment Arrangements

Hancock maintains incentive compensation plans that provide for awards of share-based compensation to employees and directors. These plans have been approved by the Company’s shareholders. Detailed descriptions of these plans were included in Note 13 to the consolidated financial statements in the Company’s annual report on Form 10-K for the year ended December 31, 2012.

A summary of option activity for the six months ended June 30, 2013 is presented below:

Options	Number of Shares			Weighted- Average Exercise Price ($)		Weighted- Average Remaining Contractual Term (Years)		Aggregate Intrinsic Value ($000)
Outstanding at January 1, 2013		1,555,296		$	38.57
Exercised		(7,134	)		23.73
Forfeited or expired		(70,443	)		47.66
Outstanding at June 30, 2013		1,477,719		$	38.21		4.9	$	247
Exercisable at June 30, 2013		1,024,893		$	40.95		3.6	$	192

The total intrinsic value of options exercised during the six months ended June 30, 2013 and 2012 was $0.1 million and $0.4 million, respectively.

A summary of the status of the Company’s nonvested restricted and performance shares as of June 30, 2013 and changes during the six months ended June 30, 2013, is presented below. These restricted and performance shares are subject to service requirements.

	Number of Shares			Weighted- Average Grant-Date Fair Value ($)
Nonvested at January 1, 2013		1,684,360		$	31.56
Granted		93,936			32.03
Vested		(23,827	)		37.00
Forfeited		(42,690	)		31.46
Nonvested at June 30, 2013		1,711,779		$	31.51

As of June 30, 2013, there was $33.2 million of total unrecognized compensation expense related to nonvested restricted and performance shares expected to vest. This compensation is expected to be recognized in expense over a weighted-average period of 3.3 years. The total fair value of shares which vested during the six months ended June 30, 2013 and 2012 was $0.7 million and $0.8 million, respectively.

During the six months ended June 30, 2013, the Company granted 67,533 performance shares with an average fair value of $32.84 per share to key members of executive and senior management. The number of 2013 performance shares that ultimately vest at the end of the three-year required service period will be based on the relative rank of Hancock’s three-year total shareholder return (TSR) among the TSRs of a peer group of fifty regional banks. The maximum number of performance shares that could vest is 200% of the target award. The fair value of the performance awards at the grant date was determined using a Monte Carlo simulation method. Compensation expense for these performance shares will be recognized on a straight-line basis over the service period.

Fair Value Disclosures [Abstract]

Fair Value

4. Fair Value

The Financial Accounting Standards Board (FASB) defines fair value as the exchange price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The FASB’s guidance also established a fair value hierarchy that prioritizes the inputs to these valuation techniques used to measure fair value, giving preference to quoted prices in active markets for identical assets or liabilities (level 1) and the lowest priority to unobservable inputs such as a reporting entity’s own data (level 3). Level 2 inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical assets or liabilities in markets that are not active, observable inputs other than quoted prices, such as interest rates and yield curves, and inputs that are derived principally from or corroborated by observable market data by correlation or other means.

Fair Value of Assets and Liabilities Measured on a Recurring Basis

The following tables present for each of the fair value hierarchy levels the Company’s assets and liabilities that are measured at fair value (in thousands) on a recurring basis in the consolidated balance sheets.

Securities classified as level 1 within the valuation hierarchy include U.S. Treasury securities, obligations of U.S. Government-sponsored agencies, and certain other debt and equity securities. Level 2 classified securities include residential mortgage-backed securities and collateralized mortgage obligations that are issued or guaranteed by U.S. government agencies, and state and municipal bonds. The level 2 fair value measurements for investment securities are obtained quarterly from a third-party pricing service that uses industry-standard pricing models. Substantially all of the model inputs are observable in the marketplace or can be supported by observable data. The Company invests only in high quality securities of investment grade quality with a targeted duration, for the overall portfolio, generally between two to five years. Company policies limit investments to securities having a rating of not less than “Baa” or its equivalent by a nationally recognized statistical rating agency. There were no transfers between valuation hierarchy levels during the periods shown.

The fair value of derivative financial instruments, which are predominantly interest rate swaps, is obtained from a third-party pricing service that uses an industry-standard discounted cash flow model that relies on inputs, such as LIBOR swap curves and Overnight Index Swap rate (“OIS”) curves, observable in the marketplace. To comply with the accounting guidance, credit valuation adjustments are incorporated in the fair values to appropriately reflect nonperformance risk for both the Company and the counterparties. Although the Company has determined that the majority of the inputs used to value the derivative instruments fall within level 2 of the fair value hierarchy, the credit value adjustments utilize level 3 inputs, such as estimates of current credit spreads. The Company has determined that the impact of the credit valuation adjustments is not significant to the overall valuation of these derivatives. As a result, the Company has classified its derivative valuations in their entirety in level 2 of the fair value hierarchy. The Company’s policy is to measure counterparty credit risk quarterly for all derivative instruments subject to master netting arrangements consistent with how market participants would price the net risk exposure at the measurement date.

The Company also has certain derivative instruments associated with the Banks’ mortgage-banking activities. These derivative instruments include interest rate lock commitments on prospective residential mortgage loans and forward commitments to sell these loans to investors on a best efforts delivery basis. The fair value of these derivative instruments is measured using observable market prices for similar instruments and classified as level 2 measurements.

Fair Value of Assets Measured on a Nonrecurring Basis

Certain assets and liabilities are measured at fair value on a nonrecurring basis. Collateral-dependent impaired loans are level 2 assets measured at the fair value of the underlying collateral based on third-party appraisals that take into consideration prices in observed transactions or other market-based information such as recent sales activity for similar assets in the property’s market.

Other real estate owned are level 3 assets that are adjusted to fair value, less estimated selling costs, upon transfer to other real estate owned. Subsequently, other real estate owned is carried at the lower of carrying value or fair value less estimated selling costs. Fair values are determined by sales agreement or third-party appraisals as discounted for estimated selling costs, information from comparable sales, and marketability of the property.

The following tables present for each of the fair value hierarchy levels the Company’s financial assets that are measured at fair value (in thousands) on a nonrecurring basis.

Accounting guidance from the FASB requires the disclosure of estimated fair value information about certain on- and off-balance sheet financial instruments, including those financial instruments that are not measured and reported at fair value on a recurring basis. The significant methods and assumptions used by the Company to estimate the fair value of financial instruments are discussed below.

Cash, Short-Term Investments and Federal Funds Sold - For these short-term instruments, the carrying amount is a reasonable estimate of fair value.

Securities – The fair value measurement for securities available for sale was discussed earlier. The same measurement techniques were applied to the valuation of securities held to maturity.

Loans, Net - The fair value measurement for certain impaired loans was discussed earlier. For the remaining portfolio, fair values were generally determined by discounting scheduled cash flows by discount rates determined with reference to current market rates at which loans with similar terms would be made to borrowers of similar credit quality.

Accrued Interest Receivable and Accrued Interest Payable - The carrying amounts are a reasonable estimate of fair value.

Deposits - The accounting guidance requires that the fair value of deposits with no stated maturity, such as noninterest-bearing demand deposits, interest-bearing checking and savings accounts, be assigned fair values equal to amounts payable upon demand (carrying amounts). The fair value of fixed-maturity certificates of deposit is estimated using the rates currently offered for deposits of similar remaining maturities.

Securities Sold under Agreements to Repurchase and Federal Funds Purchased - For these short-term liabilities, the carrying amount is a reasonable estimate of fair value.

Long-Term Debt - The fair value is estimated by discounting the future contractual cash flows using current market rates at which debt with similar terms could be obtained.

Derivative Financial Instruments – The fair value measurement for derivative financial instruments was discussed earlier.

The following tables present the estimated fair values of the Company’s financial instruments by fair value hierarchy levels and the corresponding carrying amount at June 30, 2013 and December 31, 2012 (in thousands):

Segment Reporting [Abstract]

Schedule of Segment Reporting Information

The Company’s reportable operating segments consist of the Hancock segment, which coincides generally with the Company’s Hancock Bank subsidiary, and the Whitney segment, which coincides generally with its Whitney Bank subsidiary. Each of the bank segments offers commercial, consumer and mortgage loans and deposit services as well as certain other services, such as trust and treasury management services. Although the bank segments offer the same products and services, they are managed separately due to different pricing, product demand, and consumer markets. In addition, the “Other” column in the following tables includes activities of other consolidated subsidiaries which do not constitute reportable segments under the quantitative and aggregation accounting guidelines. These subsidiaries provide investment services, insurance agency services, insurance underwriting and various other services to third parties.

Earnings Per Share [Abstract]

Earnings Per Share

7. Earnings Per Share

Hancock calculates earnings per share using the two-class method. The two-class method allocates net income to each class of common stock and participating security according to common dividends declared and participation rights in undistributed earnings. Participating securities consist of unvested stock-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents.

Following is a summary of the information used in the computation of earnings per common share using the two-class method (in thousands, except per share amounts):

Diluted	$	0.55	$	0.46	$	1.11	$	0.67

Potential common shares consist of employee and director stock options. These potential common shares do not enter into the calculation of diluted earnings per share if the impact would be anti-dilutive, i.e., increase earnings per share or reduce a loss per share. Weighted-average anti-dilutive potential common shares totaled 1,433,249 and 1,298,940 respectively for the three and six months ended June 30, 2013 and 1,107,467 and 954,326 respectively for the three and six months ended June 30, 2012.

Accounting Policies [Abstract]

Basis of Presentation

1. Basis of Presentation

The consolidated financial statements include the accounts of Hancock Holding Company and all other entities in which it has a controlling interest (the “Company”). The financial statements include all adjustments that are, in the opinion of management, necessary to present fairly the Company’s financial condition, results of operations, changes in stockholders’ equity and cash flows for the interim periods presented. Some financial information and disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the U.S. (U.S. GAAP) have been condensed or omitted in this Form 10-Q pursuant to Securities and Exchange Commission rules and regulations. These financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto included in the Company’s 2012 Annual Report on Form 10-K. Financial information reported in these financial statements is not necessarily indicative of the Company’s financial condition, results of operations, or cash flows for any other interim or annual period.

Use of Estimates

Use of Estimates

The accounting principles the Company follows and the methods for applying these principles conform with U.S. GAAP and with 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.

Critical Accounting Policies and Estimates

Critical Accounting Policies and Estimates

Allowance for Loan Losses

The allowance for loan and lease losses (“ALLL”) is a valuation account available to absorb losses on loans. The ALLL is established and maintained at an amount sufficient to cover the estimated credit losses associated with the loan and lease portfolios of the Company as of the date of the determination. Credit losses arise not only from credit risk, but also from other risks inherent in the lending process including, but not limited to, collateral risk, operational risk, concentration risk, and economic risk. As such, all related risks of lending are considered when assessing the adequacy of the allowance for loan and lease losses. Quarterly, management estimates the inherent losses in the existing loan portfolio based on a number of factors, including the Company’s past loan loss and delinquency experience, known and inherent risks in the portfolio, adverse situations that may affect the borrowers’ ability to repay, the estimated value of any underlying collateral and current economic conditions.

The analysis and methodology for estimating the ALLL include two primary elements. These elements are a loss-rate analysis of various loan groups which incorporates a historical loss rate as updated for current conditions and a specific reserve analysis for those loans considered impaired.

During the second quarter of 2013, management revised the methodology for the loss-rate analysis for the originated and acquired performing loan portfolios due to the increased size and complexity of the Company’s commercial loan portfolio. The primary changes in the methodology were to segment loans with similar risk characteristics at a more granular level and to lengthen the period used for analyzing loss emergence and estimating loss factors. The changes were implemented as of April 1, 2013 and resulted in no material change in the total amount of the allowance for loan losses. Management made the following principal changes to the methodology during the second quarter of 2013:

• Established a more granular stratification of the major loan segments to enhance the homogeneity of the loan classes. Previously, the Company segmented loans into three primary groups—commercial, residential mortgage and consumer—for the loss-rate analysis. The revised loan segments are commercial non-real estate, construction and land development, commercial real estate, residential mortgage and consumer. Both quantitative and qualitative factors are applied at the more detailed portfolio segmentation.

• Included portfolio risk ratings in loss-rate analysis. For loss-rate analysis, commercial loans (commercial non-real estate, construction and land development and commercial real estate) are further subdivided by risk rating, and retail loans (residential mortgage and consumer) are further subdivided by delinquency. Previously, the methodology indirectly incorporated risk ratings and delinquencies.

• Lengthened the loss emergence period. The Company uses an eighteen month loss emergence period for commercial loans and a twelve month loss emergence period for retail loans. Historical loss rates are calculated for each commercial segment using a weighted average of three eighteen-month periods over a fourteen quarter look-back period, and for each retail segment using a weighted average of three twelve-month periods over a twelve quarter look-back period. Previously, historical loss rates were calculated using an average of three twelve month loss emergence periods over a three year look back period for all loan segments. As circumstances dictate, management will make adjustments to the loss history to reflect differences in current conditions as compared to those during the historical loss period. Conditions to be considered include problem loan trends, current business and economic conditions, credit concentrations, lending policies and procedures, lending staff, collateral values, loan profiles and volumes, loan review quality, and changes in competition and regulations.

There were no changes in the methodology for the specific reserve analysis on loans considered to be impaired or acquired credit-impaired loans during the quarter ended June 30, 2013.

There were no other material changes or developments with respect to methodologies that the Company uses when applying what management believes are critical accounting policies and developing critical accounting estimates as disclosed in our Form 10-K for the year ended December 31, 2012.

Accounting Changes And Error Corrections [Abstract]

New Accounting Pronouncements

13. New Accounting Pronouncements

In June, the Financial Accounting Standards Board (FASB) issued an Emerging Issues Task Force (EITF) regarding companies with unrecognized tax benefits that have deferred tax assets recorded for net operating loss (NOL) or tax credit carryforwards. An entity should present its unrecognized tax benefits net against the deferred tax assets for all same jurisdiction NOL or similar tax loss carryforwards (e.g., capital losses), or tax credit carryforwards that are available and would be used by the entity to settle additional income taxes resulting from disallowance of the uncertain tax position. Netting will not be limited to only those instances when an unrecognized tax benefit is directly associated with a tax position taken in the same tax year that resulted in recognition of the NOL or tax credit carryforward for that year. The task force decided not to require any new disclosures. However, a public entity will still be required to include the unrecognized tax benefit within its existing income tax disclosures. The changes will be effective for public entities for annual periods (and interim periods within those annual periods) beginning after December 15, 2013. The adoption of this guidance is not expected to have a material impact on the Company’s financial condition or results of operations.

In February 2013, the FASB issued an Accounting Standards Update (ASU) to improve the reporting of amounts reclassified out of accumulated other comprehensive income. The updated guidance requires an entity to present, either on the face of the statement where net income is presented or in the notes, the effects on the line items of net income of significant amounts reclassified out of accumulated other comprehensive income, but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income, an entity must cross-reference to other required disclosures that provide additional details about those amounts. This ASU is effective for interim and annual reporting periods beginning after December 15, 2012. Because this updated guidance impacts only disclosures in financial statements and does not change the current requirements for reporting net income or other comprehensive income in financial statements, its implementation did not impact the Company’s financial condition or results of operations.

In October 2012, the FASB issued an ASU for entities that recognize an indemnification asset as a result of a government-assisted acquisition of a financial institution. When there is a change in the cash flows expected to be collected on the indemnification asset as a result of a change in cash flows expected to be collected on the assets subject to indemnification, the reporting entity should subsequently account for the change in the measurement of the indemnification asset on the same basis as the change in the assets subject to indemnification. Any amortization of changes in value should be limited to the contractual term of the indemnification agreement (that is, the lesser of the term of the indemnification agreement and the remaining life of the indemnified assets). The amendments in this update are effective for fiscal years, and interim periods within those years, beginning on or after December 15, 2012. The updated guidance will be applied prospectively to any new indemnification assets acquired after the date of adoption and to indemnification assets existing as of the date of adoption arising from a government-assisted acquisition of a financial institution. The Company’s current accounting policy complies with the guidance in this update.

In July 2012, FASB issued an ASU that specifies that an entity has the option first to assess qualitative factors to determine whether the existence of events and circumstances indicates that it is more likely than not that the indefinite-lived intangible asset is impaired. If, after assessing the totality of events and circumstances, an entity concludes that it is not more likely than not that the indefinite-lived intangible asset is impaired, then the entity is not required to take further action. However, if an entity concludes otherwise, then it is required to determine the fair value of the indefinite-lived intangible asset and perform the quantitative impairment test by comparing the fair value with the carrying amount. Under the guidance in this ASU, an entity also has the option to bypass the qualitative assessment for any indefinite-lived intangible asset in any period and proceed directly to performing the quantitative impairment test. An entity will be able to resume performing the qualitative assessment in any subsequent period. The guidance in this ASU is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012, with early adoption permitted. The adoption of this guidance did not have a material impact on the Company’s financial condition or results of operations.

In December 2011, the FASB issued an ASU to address the differences between international financial reporting standards (IFRS) and U.S. GAAP regarding the offsetting of assets and liabilities. Instead of proposing new criteria for netting assets and liabilities the FASB and International Accounting Standards Board (IASB) jointly issued common disclosure requirements related to offsetting arrangements that call for the disclosure of both net and gross information for these assets and liabilities, irrespective of whether they are offset on the statement of financial position. In January 2013, the FASB clarified that these disclosure requirements apply only to derivatives, repurchase and reverse repurchase agreements, and securities borrowing and lending transactions that are either offset in accordance with existing accounting guidance or subject to a master netting arrangement or similar agreement. An entity is required to provide the new disclosures for annual and interim reporting periods beginning on or after January 1, 2013. This guidance impacts only the disclosures in financial statements and did not impact the Company’s financial condition or results of operations.
