Competition

We face strong competition in attracting deposits, originating loans, and providing title services. Our most direct competition for deposits has historically come from other commercial banks, savings institutions and credit unions located in our market areas, including many large financial institutions that have greater financial and marketing resources available to them. In addition, during times of high interest rates, we have faced significant competition for investors’ funds from short-term money market securities, mutual funds and other corporate and government securities. Our ability to attract and retain customer deposits depends on our ability to generally provide a rate of return, liquidity and risk comparable to that offered by competing investment opportunities.

We experience strong competition for loan originations principally from other commercial banks, savings institutions and mortgage banking companies. We compete for loans principally through the interest rates and loan fees we charge, the efficiency and quality of services we provide borrowers and the convenient locations of our branch office network.

Employees

We had 2,631 full-time employees and 127 part-time employees as of December 31, 2012. None of these employees is represented by a collective bargaining agreement. We believe we enjoy an excellent relationship with our personnel.

Business Combinations

We continually evaluate business combination opportunities and sometimes conduct due diligence activities in connection with them. As a result, business combination discussions and, in some cases, negotiations take place, and transactions involving cash, debt or equity securities can be expected. Any future business combinations or series of business combinations that we might undertake may be material in terms of assets acquired or liabilities assumed.

Supervision and Regulation

General

The banking industry is extensively regulated under both federal and applicable state laws. The following discussion is a summary of certain statutes and regulations applicable to bank and financial holding companies and their subsidiaries and provides specific information relevant to us. Regulation of financial institutions is intended primarily for the protection of depositors, deposit insurance funds and the banking system, and generally is not intended for the protection of shareholders.

Proposals are frequently introduced to change federal and state laws and regulations applicable to us. The likelihood and timing of any such changes and the impact such changes might have on us are impossible to determine with any certainty.

We are a bank holding company and have elected to be a financial holding company with the Board of Governors of the Federal Reserve System (the “FRB”). We are subject to examination and supervision by the FRB pursuant to the Bank Holding Company Act of 1956, as amended (the “BHCA”), and are required to file reports and other information regarding our business operations and the business operations of our subsidiaries with the FRB.

Generally, the BHCA provides for “umbrella” regulation of financial holding companies by the FRB and functional regulation of holding company subsidiaries by applicable regulatory agencies. The BHCA, however, requires the FRB to examine any subsidiary of a bank holding company, other than a depository institution, engaged in activities permissible for a depository institution. The FRB is also granted the authority, in certain circumstances, to require reports of, and to examine and adopt rules applicable to any holding company subsidiary.

In general, the BHCA and the FRB’s regulations limit the nonbanking activities permissible for bank holding companies to those activities that the FRB has determined to be so closely related to banking or managing or controlling banks to be a proper incident thereto. A bank holding company that elects to be treated as a financial holding company, however, may engage in, and acquire companies engaged in, activities that are considered “financial in nature,” as defined by the Gramm-Leach-Bliley Act and FRB regulations. These activities include, among other things, securities underwriting, dealing and market-making, sponsoring mutual funds and investment companies, insurance underwriting and agency activities, and merchant banking. See “ – Financial Holding Company Status” below.

Because we are a public company, we are also subject to regulation by the Securities and Exchange Commission (the “SEC”). The SEC has established three categories of registrants for the purpose of filing periodic and annual reports. Under these regulations, we are considered to be a “large accelerated filer” and, as such, must comply with SEC large accelerated reporting requirements.

As a Louisiana-chartered commercial bank and a member of the Federal Reserve System, IBERIABANK is subject to regulation, supervision and examination by the Office of Financial Institutions of the State of Louisiana, IBERIABANK’s chartering authority, and the FRB, IBERIABANK’s primary federal regulator. IBERIABANK is referred to herein as the “Bank.” IBERIABANK is also subject to regulation, supervision and examination by the Federal Deposit Insurance Corporation (the “FDIC”). The FDIC insures the deposits of IBERIABANK to the maximum extent permitted by law.

State and federal laws govern the activities in which IBERIABANK may engage, the investments it may make and the aggregate amount of loans that may be granted to one borrower. Various consumer and compliance laws and regulations also affect IBERIABANK’s operations.

The banking industry is affected by the monetary and fiscal policies of the FRB. An important function of the FRB is to regulate the national supply of bank credit to moderate recessions and to curb inflation. Among the instruments of monetary policy used by the FRB to implement its objectives are: open-market operations in U.S. government securities, changes in the discount rate and the federal funds rate (which is the rate banks charge each other for overnight borrowings) and changes in reserve requirements on bank deposits.

In addition to federal and state banking laws and regulations, we and certain of our subsidiaries and affiliates, including those that engage in securities brokerage and insurance activities, are subject to other federal and state laws and regulations, and supervision and examination by other state and federal regulatory agencies, including

3

the Financial Industry Regulatory Authority (“FINRA”), the U.S. Department of Housing and Urban Development (“HUD”), the SEC and various state insurance and securities regulators.

The Dodd-Frank Act

The Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”), which was enacted in 2010, significantly restructured financial regulation in the United States, including through the creation of a new resolution authority, mandating higher capital and liquidity requirements, requiring banks to pay increased fees to regulatory agencies, and through numerous other provisions intended to strengthen the financial services sector.

The implications of the Dodd-Frank Act for the Company’s businesses will depend to a large extent on the manner in which rules adopted pursuant to the Dodd-Frank Act are implemented by the primary U.S. financial regulatory agencies as well as potential changes in market practices and structures in response to the requirements of the Dodd-Frank Act and financial reforms in other jurisdictions. Among other things:

• The Dodd-Frank Act repealed the federal prohibitions on the payment of interest on demand deposits, thereby permitting depository institutions to pay interest on business transaction and other deposit accounts.

• The Dodd-Frank Act centralized responsibility for consumer financial protection by creating a new independent federal agency, the Consumer Financial Protection Bureau (“CFPB”), and giving it broad powers to supervise and enforce compliance with federal consumer protection laws. The CFPB has broad rule-making authority for a wide range of consumer protection laws that apply to IBERIABANK, including the authority to prohibit “unfair, deceptive or abusive” acts and practices. The CFPB has examination and primary enforcement authority over all depository institutions with more than $10 billion in assets, including IBERIABANK. The CFPB has authority to prevent unfair, deceptive or abusive acts and practices in connection with the offering of consumer financial products. The CFPB is authorized to establish certain minimum standards for the origination of residential mortgages, including a determination of the borrower’s ability to repay. In addition, borrowers are allowed to raise certain defenses to foreclosures if they receive any loan other than a “qualified mortgage” as defined by the CFPB. States are permitted to adopt consumer protection laws and standards that are more stringent than those adopted at the federal level and, in certain circumstances, state attorneys general are permitted to enforce compliance with both the state and federal laws and regulations

• The “Durbin Amendment” provisions of the Dodd-Frank Act provided that debit card interchange fees must be reasonable and proportional to the cost incurred by the issuer with respect to the transaction. In 2011, the FRB adopted regulations setting the maximum permissible interchange fee as the sum of 21 cents per transaction and 5 basis points multiplied by the value of the transaction, with an additional adjustment of up to one cent per transaction if the issuer implements certain fraud-prevention standards. In 2012, the Durbin Amendment debit card transaction impacted the Company’s financial results by lowering the average fee earned per transaction.

• The Dodd-Frank Act requires various U.S. financial regulatory agencies to implement comprehensive rules governing the supervision, structure, trading and regulation of swap and over the-counter derivative markets and participants. The Dodd-Frank Act requires a large number of rules in this area, many of which are not yet final.

The Dodd-Frank Act requires the federal financial regulatory agencies to adopt rules that prohibit banks and their affiliates from engaging in proprietary trading and investing in and sponsoring certain unregistered investment companies (defined as hedge funds and private equity funds), with implementation anticipated as early as July 2012. The statutory provision is commonly called the “Volcker Rule”. In 2011, federal regulators proposed rules to implement the Volcker Rule that included an extensive request for comments on the proposal. The proposed rules are highly complex, and many aspects of their application remain uncertain. Due to the complexity of the new rules, the challenges of agency coordination and the volume of comments received, implementation of the Volcker Rule has been delayed.

We do not currently anticipate that the Volcker Rule will have a material effect on our operations. Until a final rule is adopted, the precise financial impact of the rule cannot be determined.

New laws or regulations or changes to existing laws and regulations (including changes in interpretation or enforcement) could materially adversely affect our financial condition or results of operations. Many aspects of the Dodd-Frank Act are subject to further rulemaking and will take effect over several years. The overall financial impact on the Company and its subsidiaries or the financial services industry generally cannot be anticipated at this time.

Holding Company Structure

We have one Louisiana-chartered commercial bank subsidiary, one title insurance company subsidiary, one subsidiary to provide equity research, institutional sales and trading, and corporate financial services, one subsidiary to provide wealth management and trust services, and multiple subsidiaries to operate corporate assets, including our fractional ownership of an aircraft and our investment in purchased tax credits, as well as numerous other non-bank subsidiaries of these first tier subsidiaries. Exhibit 21 of this Report on Form 10-K lists all of our current subsidiaries.

IBERIABANK is subject to affiliate transaction restrictions under federal laws, which limit the transfer of funds by a subsidiary bank or its subsidiaries to its parent corporation or any non-bank subsidiary of its parent corporation, whether in the form of loans, extensions of credit, investments, or asset purchases. Furthermore, such loans and extensions of credit must be secured within specified amounts. In addition, all affiliate transactions must be conducted on terms and under circumstances that are substantially the same as such transactions with unaffiliated entities. Such extensions of credit must be made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with third parties and must not involve more than the normal risk of repayment or present other unfavorable features. See “Affiliate Transactions” below.

As a matter of policy which has been codified by the Dodd-Frank Act, the FRB expects a bank holding company to act as a source of financial and managerial strength to each of its subsidiary banks and to commit resources to support each such subsidiary bank. Under this source of strength doctrine, the FRB may require a bank holding company to make capital injections into a troubled subsidiary bank. They may charge the bank holding company with engaging in unsafe and unsound practices if it fails to commit resources to such a subsidiary bank or if it undertakes actions that the FRB believes might jeopardize its ability to commit resources to such subsidiary bank. A capital injection may be required at times when the holding company does not have the resources to provide it. In addition, any capital loans by a bank holding company to its subsidiary bank are subordinate in right of payment to deposits and to certain other indebtedness of such subsidiary bank. In the event of a bank holding company’s bankruptcy, any commitment by the bank holding company to a federal bank regulatory agency to maintain the capital of a subsidiary bank will be assumed by the bankruptcy trustee and entitled to a priority of payment.

Any loans by a holding company to a subsidiary bank are subordinate in right of payment to deposits and to certain other indebtedness of such subsidiary bank. In the event of a bank holding company’s bankruptcy, the bankruptcy trustee will assume any commitment by the holding company to a federal bank regulatory agency to maintain the capital of a subsidiary bank. Moreover, the bankruptcy law provides that claims based on any such commitment will be entitled to a priority of payment over the claims of the institution’s general unsecured creditors, including the holders of its note obligations.

Louisiana law permits the Commissioner of the Louisiana Office of Financial Institutions to require a special assessment of shareholders of a Louisiana-chartered bank whose capital has become impaired to remedy an impairment in such bank’s capital stock. This statute also provides that the Commissioner may suspend the bank’s certificate of authority until the capital is restored. As the sole shareholder of IBERIABANK, we are subject to such statute.

Moreover, the claims of a receiver of an insured depository institution for administrative expenses and the claims of holders of deposit liabilities of such an institution are accorded priority over the claims of general unsecured creditors of such an institution, including the holders of the institution’s note obligations, in the event of liquidation or other resolution of such institution. Claims of a receiver for administrative expenses and claims of holders of deposit liabilities of IBERIABANK, including the FDIC as the insurer of such holders, would receive priority over the holders of notes and other senior debt of IBERIABANK in the event of liquidation or other resolution and over our interests as sole shareholder of IBERIABANK.

The FRB maintains a bank holding company rating system that emphasizes risk management, introduces a framework for analyzing and rating financial factors, and provides a framework for assessing and rating the potential impact of non-depository entities of a holding company on its subsidiary depository institution(s).

A composite rating is assigned based on the foregoing three components, but a fourth component is also rated, reflecting generally the assessment of depository institution subsidiaries by their principal regulators. Ratings are made on a scale of 1 to 5 (1 highest) and are not made public. The composite ratings assigned to us, like those

5

assigned to other financial institutions, are confidential and may not be directly disclosed, except to the extent required by law.

Acquisitions. The Company complies with numerous laws relating to its acquisition activity. Under the BHCA, a bank holding company may not directly or indirectly acquire ownership or control of more than 5% of the voting shares or substantially all of the assets of any bank holding company or bank or merge or consolidate with another bank holding company without the prior approval of the FRB. Current Federal law authorizes interstate acquisitions of banks and bank holding companies without geographic limitation. Furthermore, a bank headquartered in one state is authorized to merge with a bank headquartered in another state, as long as neither of the states have opted out of such interstate merger authority prior to such date, and subject to any state requirement that the target bank shall have been in existence and operating for a minimum period of time, not to exceed five years; and subject to certain deposit market-share limitations. After a bank has established branches in a state through an interstate merger transaction, the bank may establish and acquire additional branches at any location in the state where a bank headquartered in that state could have established or acquired branches under applicable federal or state law.

In 2012, we consummated the acquisition of Florida Gulf Bancorp, Inc. and its wholly owned subsidiary, Florida Gulf Bank, headquartered in Fort Meyers, Florida, with eight branches in the Fort Meyers – Cape Coral, Florida, market.

Safety and Soundness Regulations. The FRB has enforcement powers over bank holding companies and their non-banking subsidiaries. The FRB has authority to prohibit activities that represent unsafe or unsound practices or constitute violations of law, rule, regulation, administrative order or written agreement with a federal regulator. These powers may be exercised through the issuance of cease and desist orders, civil money penalties or other formal or informal actions.

There also are a number of obligations and restrictions imposed on bank holding companies and their depository institution subsidiaries by federal law and regulatory policy that are designed to reduce potential loss exposure to the depositors of such depository institutions and to the FDIC insurance funds in the event the depository institution is insolvent or is in danger of becoming insolvent. For example, under requirements of the FRB with respect to bank holding company operations, a bank holding company is required to serve as a source of financial strength to its subsidiary depository institutions and to commit financial resources to support such institutions in circumstances where it might not do so otherwise. In addition, the “cross-guarantee” provisions of federal law require insured depository institutions under common control to reimburse the FDIC for any loss suffered or reasonably anticipated by the Deposit Insurance Fund (“DIF”) as a result of the insolvency of commonly controlled insured depository institutions or for any assistance provided by the FDIC to commonly controlled insured depository institutions in danger of failure. The FDIC may decline to enforce the cross-guarantee provision if it determines that a waiver is in the best interests of the DIF. The FDIC’s claim for reimbursement under the cross guarantee provisions is superior to claims of shareholders of the insured depository institution or its holding company, but is subordinate to claims of depositors, secured creditors and nonaffiliated holders of subordinated debt of the commonly controlled insured depository institution.

Banking regulators also have broad enforcement powers over IBERIABANK, including the power to impose fines and other civil and criminal penalties, and to appoint a conservator in order to conserve the assets of any such institution for the benefit of depositors and other creditors.

Dividends. We are a legal entity separate and distinct from our subsidiaries. The majority of our revenue is from dividends paid us by IBERIABANK. IBERIABANK is subject to federal and state laws and regulations that limit the amount of dividends it can pay. In addition, we and IBERIABANK are subject to various regulatory restrictions relating to the payment of dividends, including requirements to maintain capital at or above regulatory minimums, and to remain “well-capitalized” under the prompt corrective action rules. The FRB has indicated generally that it may be an unsafe or unsound practice for a bank holding company to pay dividends unless the bank holding company’s net income over the preceding year is sufficient to fund the dividends and the expected rate of earnings retention is consistent with the organization’s capital needs, asset quality and overall financial condition.

In addition to the limitations placed on the payment of dividends at the holding company level, there are various legal and regulatory limits on the extent to which IBERIABANK may pay dividends or otherwise supply funds to us. IBERIABANK is subject to laws and regulations of Louisiana, which place certain restrictions on the

6

payment of dividends. Additionally, as a member of the Federal Reserve System, IBERIABANK is subject to regulations of the FRB.

We do not expect that these laws, regulations or policies will materially affect the ability of IBERIABANK to pay dividends. Additional information is provided in Note 24 to the Consolidated Financial Statements incorporated herein by reference.

FDIC Insurance. IBERIABANK pays deposit insurance premiums to the FDIC based on assessment rates established by the FDIC. These rates generally depend upon a combination of regulatory ratings and financial ratios. Regulatory ratings reflect the applicable bank regulatory agency’s evaluation of the financial institution’s capital, asset quality, management, earnings, liquidity and sensitivity to risk (“CAMELS”). Assessment rates for institutions that are in the lowest risk category currently vary from seven to twenty-four basis points per $100 of insured deposits, and may be increased or decreased by the FDIC on a semi-annual basis. Such base assessment rates are subject to adjustments. Insurance of deposits may be terminated by the FDIC upon a finding that the institution has engaged in unsafe and unsound practices, is in an unsafe or unsound condition to continue operations, or has violated any applicable law, regulation, rule, order or condition imposed by the FDIC.

In 2011, the FDIC adopted a rule to revise the deposit insurance assessment system for large institutions. The rule creates a two scorecard system for large institutions, one for most large institutions that have more than $10 billion in assets, and another for “highly complex” institutions that have over $50 billion in assets and are fully owned by a parent with over $500 billion in assets. Each scorecard has a performance score and a loss-severity score that is combined to produce a total score, which is translated into an initial assessment rate. In calculating these scores, the FDIC will continue to utilize the bank’s supervisory CAMELS ratings and will assess an institution’s ability to withstand asset-related stress and funding-related stress. The rule also eliminates the use of risk categories and long-term debt issuer ratings for calculating risk-based assessments for institutions having more than $10 billion in assets. The FDIC is authorized to make discretionary adjustments to the total score based upon significant risk factors that are not adequately captured in the scorecard. The total score will then translate to an initial base assessment rate.

Also in 2011, the deposit insurance assessment base changed from total domestic deposits to the average consolidated total assets of the depository institution minus its average tangible equity, pursuant to a rule issued by the FDIC as required by the Dodd-Frank Act.

In 2009, the FDIC implemented a rule requiring insured institutions to prepay their estimated quarterly risk-based assessments for the fourth quarter of 2009, and for all of 2010, 2011 and 2012. Such prepaid assessments were paid on December 30, 2009, along with each institution’s quarterly risk-based deposit insurance assessment for the third quarter of 2009 (assuming 5% annual growth in deposits between the third quarter of 2009 and the end of 2012 and taking into account, for 2011 and 2012, the annualized three basis point increase discussed below).

A minimum ratio of deposit insurance reserves to estimated insured deposits, or designated reserve ratio (the “DRR”), of 1.15% is applicable prior to September 2020, and 1.35% thereafter. In 2010, the FDIC issued a final rule setting the DRR at 2%. Because the DRR fell below 1.15% as of June 30, 2008, and was expected to remain below 1.15% the FDIC was required to establish and implement a Restoration Plan that would restore the reserve ratio to at least 1.15% within five years. In 2008, the FDIC adopted such a restoration plan (the “Restoration Plan”). In 2009, in light of the extraordinary challenges that were facing the banking industry, the FDIC amended the Restoration Plan to allow seven years for the reserve ratio to return to 1.15%. The FDIC adopted a final rule that imposed a five basis point special assessment on each institution’s assets minus Tier 1 capital (as of June 30, 2009). Such special assessment was collected on September 30, 2009. In October 2009, the FDIC passed a final rule extending the term of the Restoration Plan to eight years. Such final rule also included a provision that implemented a uniform three basis point increase in assessment rates, effective January 1, 2011, to help ensure that the reserve ratio returns to at least 1.15% within the eight year period called for by the Restoration Plan. In October 2010, the FDIC adopted a new restoration plan to ensure the DRR reaches 1.35% by September 2020. As part of the revised plan, the FDIC announced it would forego the uniform three-basis point increase in assessment rates scheduled to take place in January 2011. The FDIC at least semi-annually updates its income and loss projections for the DIF and, if necessary, propose rules to further increase assessment rates.

Insurance of deposits may be terminated by the FDIC upon a finding that the institution has engaged in unsafe and unsound practices, is in an unsafe or unsound condition to continue operations, or has violated any applicable law, regulation, rule, order or condition imposed by the FDIC.

In addition, the Deposit Insurance Funds Act of 1996 authorized the Financing Corporation (“FICO”) to impose assessments on DIF applicable deposits in order to service the interest on FICO’s bond obligations from deposit insurance fund assessments. The amount assessed on individual institutions by FICO is in addition to the amount, if any, paid for deposit insurance according to the FDIC’s risk-related assessment rate schedules. FICO assessment rates may be adjusted quarterly to reflect a change in assessment base. IBERIABANK recognized $0.8 million of expense related to its FICO assessments in 2012.

We cannot predict whether the FDIC will in the future further increase deposit insurance assessment levels.

Capital Requirements. The FRB has issued risk-based capital ratio and leverage ratio guidelines for bank holding companies. The risk-based capital ratio guidelines establish a systematic analytical framework that:

• makes regulatory capital requirements sensitive to differences in risk profiles among banking organizations,

• takes off-balance sheet exposures into explicit account in assessing capital adequacy, and

• minimizes disincentives to holding liquid, low-risk assets.

Under the guidelines and related policies, bank holding companies must maintain capital sufficient to meet both a risk-based asset ratio test and a leverage ratio test on a consolidated basis. The risk-based ratio is determined by allocating assets and specified off-balance sheet commitments into four weighted categories, with higher weighting assigned to categories perceived as representing greater risk. The risk-based ratio represents capital divided by total risk weighted assets. The leverage ratio is core capital divided by total assets adjusted as specified in the guidelines.

Generally, under the applicable guidelines, a financial institution’s capital is divided into two tiers. Institutions that must incorporate market risk exposure into their risk-based capital requirements may also have a third tier of capital in the form of restricted short-term subordinated debt. These tiers are:

• “Tier 1”, or core capital, includes total equity plus qualifying capital securities and minority interests, excluding unrealized gains and losses accumulated in other comprehensive income, and non-qualifying intangible and servicing assets.

• “Tier 2”, or supplementary capital, includes, among other things, cumulative and limited-life preferred stock, mandatory convertible securities, qualifying subordinated debt, and the allowance for credit losses, up to 1.25% of risk-weighted assets.

• “Total capital” is Tier 1 plus Tier 2 capital.

The FRB and the other federal banking regulators require that all intangible assets (net of deferred tax), except originated or purchased mortgage-servicing rights, non-mortgage servicing assets, and purchased credit card relationships, be deducted from Tier 1 capital. However, the total amount of these items included in capital cannot exceed 100% of its Tier 1 capital.

Under the risk-based guidelines, financial institutions are required to maintain a risk-based ratio of 8%, with 4% being Tier 1 capital. The appropriate regulatory authority may set higher capital requirements if it believes an institution’s circumstances warrant.

Under the leverage guidelines, financial institutions are required to maintain a leverage ratio of at least 3%. The minimum ratio is applicable only to financial institutions that meet certain specified criteria, including excellent asset quality, high liquidity, low interest rate risk exposure, and the highest regulatory rating. Financial institutions not meeting these criteria are required to maintain a minimum Tier 1 leverage ratio of 4%.

Special minimum capital requirements apply to equity investments in non-financial companies. The requirements consist of a series of deductions from Tier 1 capital that increase within a range from 8% to 25% of the adjusted carrying value of the investment.

8

Failure to meet applicable capital guidelines could subject the financial institution to a variety of enforcement remedies available to the federal regulatory authorities. These include limitations on the ability to pay dividends, the issuance by the regulatory authority of a capital directive to increase capital, and the termination of deposit insurance by the FDIC. In addition, the financial institution could be subject to the measures described below under “Prompt Corrective Action” as applicable to “under-capitalized” institutions.

The risk-based capital standards of the FRB and the FDIC specify that evaluations by the banking agencies of a bank’s capital adequacy will include an assessment of the exposure to declines in the economic value of the bank’s capital due to changes in interest rates. These banking agencies issued a joint policy statement on interest rate risk describing prudent methods for monitoring such risk that rely principally on internal measures of exposure and active oversight of risk management activities by senior management.

Basel II Standards. In 2004, the Basel Committee on Banking Supervision (the “Basel Committee”) published a new set of risk-based capital standards (“Basel II”) in order to update the then-current regulatory capital regime that had been in place since 1988 (“Basel I”). Unlike the one-size fits all approach to regulatory capital set forth in Basel I, Basel II provided two approaches for setting capital standards for credit risk – an internal ratings-based approach tailored to individual institutions’ circumstances and a standardized approach that bases risk-weighting on external credit assessments to a much greater extent than permitted in the existing risk-based capital guidelines. Basel II also set capital requirements for operational risk and refine the existing capital requirements for market risk exposures. A definitive final rule for implementing the advanced approaches of Basel II in the United States, which applies only to internationally active banking organizations, or “core banks” (defined as those with consolidated total assets of $250 billion or more or consolidated on-balance sheet foreign exposures of $10 billion or more) became effective in 2008. Other U.S. banking organizations were allowed to adopt the requirements of this rule (if they meet applicable qualification requirements), but were not required to comply. The rule also allowed a banking organization’s primary federal regulator to determine that application of the rule would not be appropriate in light of the bank’s asset size, level of complexity, risk profile or scope of operations.

In 2008, the U.S. bank regulatory agencies issued a proposed rule that would provide banking organizations that do not use the advanced approaches of Basel II with the option to implement an alternative risk-based capital framework containing only certain elements of Basel II. This framework would adopt the standardized approach of Basel II for credit risk, the basic indicator approach of Basel II for operational risk, and related disclosure requirements. While this proposed rule generally paralleled the relevant approaches under Basel II, it diverged where United States markets have unique characteristics and risk profiles, most notably with respect to risk weighting residential mortgage exposures.

Leverage Requirements. Neither Basel I nor Basel II included a leverage requirement as an international standard. The FRB has established minimum leverage ratio guidelines for bank holding companies to be considered well-capitalized. These guidelines provide for a minimum ratio of Tier 1 capital to average total assets, less goodwill and certain other intangible assets, of 3% for bank holding companies that meet certain specified criteria, including having the highest regulatory rating. All other bank holding companies generally are required to maintain a ratio of at least 4%.

The guidelines also provide that bank holding companies experiencing internal growth or making acquisitions will be expected to maintain strong capital positions substantially above the minimum supervisory levels without significant reliance on intangible assets. Furthermore, the FRB has indicated that it will consider a “tangible Tier 1 capital leverage ratio” (deducting all intangibles) and other indicators of capital strength in evaluating proposals for expansion or new activities.

Basel III Standards. The Basel Committee released in 2010 revised final frameworks for the regulation of capital and liquidity of internationally active banking organizations. These new frameworks are generally referred to as “Basel III.” Although Basel III is intended to be implemented by participating countries for large, internationally active banks, it was anticipated that its provisions would be considered by U.S. banking regulators in developing new regulations applicable to other banks in the United States, including those developed pursuant to directives in the Dodd-Frank Act. In 2012, the FRB proposed new capital requirements that are consistent with Basel III. If adopted as proposed, the proposed rules will require, among other things, a minimum common equity Tier 1 capital ratio of 4.5%, net of regulatory deductions, and establish a capital conservation buffer of an additional 2.5% of common equity to risk-weighted assets above the regulatory minimum capital requirement, establishing a minimum common equity Tier 1 ratio plus capital conservation buffer at 7%. In addition, the proposed rules increase the minimum Tier 1 capital requirement from 4% to 6% of risk-weighted assets. The proposed rules also specify that a bank with a capital conservation buffer of less than 2.5% would potentially face limitations on capital distributions and bonus payments to executives.

Liquidity Requirements. Historically, regulation and monitoring of bank and bank holding company liquidity has been addressed as a supervisory matter without required formulaic measures. The Basel III framework requires banks and bank holding companies to measure their liquidity against specific liquidity tests that, although similar in some respects to liquidity measures historically applied by banks and regulators for management and supervisory purposes, going forward such measures will be required by regulation. One test, the liquidity coverage ratio (“LCR”), is designed to ensure that the banking entity maintains an adequate level of unencumbered high-quality liquid assets equal to the entity’s expected net cash outflow for a 30-day time horizon. The other test, the net stable funding ratio (“NSFR”), is designed to promote more medium- and long-term funding of the assets and activities of banking entities over a one-year time horizon. These requirements are intended to incent banking entities to increase their holdings of U.S. Treasury securities and other sovereign debt as a component of assets and increase the use of long-term debt as a funding source.

In January 2013, the Basel Committee revised the LCR to incorporate amendments to the definitions of high-quality liquid assets and net cash outflows. The Basel Committee also revised the LCR phase-in timetable. The LCR will be introduced as planned on January 1, 2015, but the minimum requirement will begin at 60%, rising in equal annual steps of 10%. The NSFR will not be introduced as a requirement until January 1, 2018.

In November 2012, the U.S. federal banking agencies announced that they are delaying the implementation of the proposed Basel III rules. They gave no timetable for the implementation.

The Basel III rules are subject to change. In addition, many aspects of the Dodd-Frank Act are subject to future rulemaking. We, therefore, cannot anticipate the impact of new capital regulations at this time.

Joint Supervisory Guidance on Stress Testing. In May 2012, the federal banking agencies issued joint supervisory guidance on stress testing. The guidance addresses stress testing in connection with overall risk management, including capital and liquidity planning. The guidance outlines general principles for stress testing, applicable to all FRB-supervised banking organizations with more than $10 billion in total consolidated assets. The guidance highlights the importance of stress testing as an ongoing risk management practice that supports a banking organization’s forward-looking assessment of its risks. It outlines broad principles for a satisfactory stress testing framework and describes the manner in which stress testing should be employed as an integral component of risk management. The Dodd-Frank Act’s stress testing requirements are being implemented through separate notices of proposed rulemaking by the respective agencies.

Prompt Corrective Action. The Federal Deposit Insurance Corporation Improvement Act of 1991, known as FIDICIA, requires federal banking regulatory authorities to take “prompt corrective action” with respect to depository institutions that do not meet minimum capital requirements. For these purposes, FIDICIA establishes five capital tiers: “well-capitalized,” “adequately-capitalized,” “under-capitalized,” “significantly under-capitalized,” and “critically under-capitalized.”

An institution is deemed to be:

• “well-capitalized” if it has a total risk-based capital ratio of 10% or greater, a Tier 1 risk-based capital ratio of 6% or greater, and a Tier 1 leverage ratio of 5% or greater and is not subject to a regulatory order, agreement, or directive to meet and maintain a specific capital level for any capital measure;

• “adequately-capitalized” if it has a total risk-based capital ratio of 8% or greater, a Tier 1 risk-based capital ratio of 4% or greater, and, generally, a Tier 1 leverage ratio of 4% or greater and the institution does not meet the definition of a “well-capitalized” institution;

• “under-capitalized” if it does not meet one or more of the “adequately-capitalized” tests;

• “significantly under-capitalized” if it has a total risk-based capital ratio that is less than 6%, a Tier 1 risk-based capital ratio that is less than 3%, or a Tier 1 leverage ratio that is less than 3%; and

• “critically under-capitalized” if it has a ratio of tangible equity, as defined in the regulations, to total assets that is equal to or less than 2%.

10

Throughout 2012, our regulatory capital ratios and those of the Bank were in excess of the levels established for “well-capitalized” institutions.

(in thousands of dollars)		“Well- Capitalized” Minimums			At December 31, 2012
					Actual			Excess Capital
Ratios:
Tier 1 leverage ratio	Consolidated		5.00	%		9.70	%	$	574,140
	IBERIABANK		5.00			8.57			433,657
Tier 1 risk-based capital ratio	Consolidated		6.00			12.92			634,956
	IBERIABANK		6.00			11.41			493,695
Total risk-based capital ratio	Consolidated		10.00			14.19			384,518
	IBERIABANK		10.00			12.68			244,337

FDICIA generally prohibits a depository institution from making any capital distribution, including payment of a cash dividend or paying any management fee to its holding company, if the depository institution would be “under-capitalized” after such payment. “Under-capitalized” institutions are subject to growth limitations and are required by the appropriate federal banking agency to submit a capital restoration plan. If any depository institution subsidiary of a holding company is required to submit a capital restoration plan, the holding company would be required to provide a limited guarantee regarding compliance with the plan as a condition of approval of such plan.

If an “under-capitalized” institution fails to submit an acceptable plan, it is treated as if it is “significantly under-capitalized.” “Significantly under-capitalized” institutions may be subject to a number of requirements and restrictions, including orders to sell sufficient voting stock to become “adequately-capitalized,” requirements to reduce total assets, and cessation of receipt of deposits from correspondent banks.

“Critically under-capitalized” institutions may not, beginning 60 days after becoming “critically under-capitalized,” make any payment of principal or interest on their subordinated debt. In addition, “critically under-capitalized” institutions are subject to appointment of a receiver or conservator within 90 days of becoming so classified.

Under FDICIA, a depository institution that is not “well-capitalized” is generally prohibited from accepting brokered deposits and offering interest rates on deposits higher than the prevailing rate in its market. As previously stated, the Bank is “well-capitalized” and the FDICIA brokered deposit rule did not adversely affect its ability to accept brokered deposits. IBERIABANK had $398.1 million of such brokered deposits at December 31, 2012.

Additional information is provided in Note 18 to the Consolidated Financial Statements and in “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Capital Resources” in Exhibit 13 to this Form 10-K incorporated herein by reference.

Financial Holding Company Status. A bank holding company meeting certain requirements may qualify and elect to become a financial holding company, permitting the bank holding company to engage in additional activities that are financial in nature or incidental or complementary to financial activity. The BHCA expressly lists the following activities as financial in nature:

• lending, trust and other banking activities;

• insuring, guaranteeing or indemnifying against loss or harm, or providing and issuing annuities and acting as principal, agent or broker for these purposes, in any state;

• providing financial, investment or advisory services;

11

• issuing or selling instruments representing interests in pools of assets permissible for a bank to hold directly;

• underwriting, dealing in or making a market in securities;

• other activities that the FRB may determine to be so closely related to banking or managing or controlling banks as to be a proper incident to managing or controlling banks;

• foreign activities permitted outside of the United States if the FRB has determined them to be usual in connection with banking operations abroad;

• merchant banking through securities or insurance affiliates; and

• insurance company portfolio investments.

For a bank holding company to be eligible to elect financial holding company status, the holding company must be both “well capitalized” and “well managed” under applicable regulatory standards, and all of its subsidiary banks also must be “well-capitalized” and “well-managed” and must have received at least a satisfactory rating on such institution’s most recent examination under the Community Reinvestment Act of 1977 (the “CRA”). A financial holding company that continues to meet all of such requirements may engage directly or indirectly in activities considered financial in nature (discussed above), either de novo or by acquisition, as long as it gives the FRB after-the-fact notice of the new activities. If a financial holding company fails to continue to meet any of the prerequisites for financial holding company status after engaging in activities not permissible for bank holding companies that have not elected to be treated as financial holding companies, the company must enter into an agreement with the FRB that it will comply with all applicable capital and management requirements. If the financial holding company does not return to compliance within 180 days, or such longer period as agreed to by the FRB, the FRB may order the company to discontinue existing activities that are not generally permissible for bank holding companies or divest investments in companies engaged in such activities. In addition, if any banking subsidiary of a financial holding company receives a CRA rating of less than satisfactory, the holding company would be prohibited from engaging in any additional activities other than those permissible for bank holding companies that are not financial holding companies.

Affiliate Transactions. IBERIABANK is subject to Regulation W, which comprehensively implemented statutory restrictions on transactions between a bank and its affiliates. Regulation W combines the FRB’s interpretations and exemptions relating to Sections 23A and 23B of the Federal Reserve Act. Regulation W and Section 23A place limits on the amount of loans or extensions of credit to, investments in, or certain other transactions with affiliates, and on the amount of advances to third parties collateralized by the securities or obligations of affiliates. In general, IBERIABANK’s “affiliates” are IBERIABANK Corporation and our non-bank subsidiaries.

Regulation W and Section 23B prohibit, among other things, a bank from engaging in certain transactions with affiliates unless the transactions are on terms substantially the same, or at least as favorable to the bank, as those prevailing at the time for comparable transactions with non-affiliated companies.

IBERIABANK is also subject to certain restrictions on extensions of credit to executive officers, directors, certain principal shareholders and their related interests. Such extensions of credit must be made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with third parties and must not involve more than the normal risk of repayment or present other unfavorable features.

Bank Secrecy Act. The Bank Secrecy Act, as amended by the USA Patriot Act of 2001 and related regulations require insured depository institutions, broker-dealers, and certain other financial institutions to have policies, procedures, and controls to detect, prevent, and report money laundering and terrorist financing. The statute and its regulations also provide for information sharing, subject to conditions, between federal law enforcement agencies and financial institutions, as well as among financial institutions, for counter-terrorism purposes. Federal banking regulators are required, when reviewing bank holding company acquisition and bank merger applications, to take into account the effectiveness of the anti-money laundering activities of the applicants.

Consumer Privacy and Other Consumer Protection Laws. We, like all other financial institutions, are required to maintain the privacy of our customers’ non-public, personal information. Such privacy requirements, as established by the Gramm-Leach-Bliley Act of 1999, direct financial institutions to:

• provide notice to our customers regarding privacy policies and practices,

12

• inform our customers regarding the conditions under which their non-public personal information may be disclosed to non-affiliated third parties, and

• give our customers an option to prevent disclosure of such information to non-affiliated third parties.

Under the Fair and Accurate Credit Transactions Act of 2003, our customers may also opt out of information sharing between and among us and our affiliates. We are also subject, in connection with our lending and leasing activities, to numerous federal and state laws aimed at protecting consumers, including the Home Mortgage Disclosure Act, the Real Estate Settlement Procedures Act, the Equal Credit Opportunity Act, the Truth in Lending Act, and the Fair Credit Reporting Act.

Incentive Compensation. Guidelines adopted by the federal banking agencies prohibit excessive compensation as an unsafe and unsound practice and describe compensation as excessive when the amounts paid are unreasonable or disproportionate to the services performed by an executive officer, employee, director or principal stockholder.

In 2010, the FRB issued guidance on incentive compensation policies intended to ensure that the incentive compensation policies of banking organizations do not undermine the safety and soundness of such organizations by encouraging excessive risk-taking. The guidance covers all employees that have the ability to materially affect the risk profile of an organization, either individually or as part of a group, and is based upon the key principles that a banking organization’s incentive compensation arrangements should (i) provide incentives that do not encourage risk-taking beyond the organization’s ability to effectively identify and manage risks, (ii) be compatible with effective internal controls and risk management, and (iii) be supported by strong corporate governance, including active and effective oversight by the organization’s board of directors. Any deficiencies in compensation practices that are identified may be incorporated into the organization’s supervisory ratings, which can affect its ability to make acquisitions or perform other actions. The guidance provides that enforcement actions may be taken against a banking organization if deficient incentive compensation arrangements or related risk-management control or governance processes employed by the organization pose a risk to the organization’s safety and soundness and the organization is not taking prompt and effective measures to correct such deficiencies.

The Dodd-Frank Act requires the federal bank regulatory agencies and the SEC to establish joint regulations or guidelines prohibiting incentive-based payment arrangements at specified regulated entities having at least $1 billion in total assets that encourage inappropriate risks by providing an executive officer, employee, director or principal shareholder with excessive compensation, fees, or benefits or that could lead to material financial loss to the entity. In addition, these regulators must establish regulations or guidelines requiring enhanced disclosure of incentive-based compensation arrangements.

The scope and content of regulatory policies on incentive compensation have not been finalized. It cannot be determined at this time whether compliance with such future policies will adversely affect the ability of the Company and its subsidiaries to hire, retain and motivate their key employees.

Sarbanes-Oxley Act of 2002. The Sarbanes-Oxley Act of 2002 (the “SOX Act”) implements a broad range of corporate governance, accounting and disclosure requirements for public companies, and also for their directors and officers. SEC rules adopted to implement SOX Act requirements require our chief executive and chief financial officer to certify certain financial and other information included in our quarterly and annual reports. The rules also require these officers to certify that they are responsible for establishing, maintaining and regularly evaluating the effectiveness of our financial reporting and disclosure controls and procedures; that they have made certain disclosures to the auditors and to the Audit Committee of the board of directors about our controls and procedures; and that they have included information in their quarterly and annual filings about their evaluation and whether there have been significant changes to the controls and procedures or other factors which would significantly impact these controls subsequent to their evaluation. Section 404 of the SOX Act requires management to undertake an assessment of the adequacy and effectiveness of our internal controls over financial reporting and requires our auditors to attest to and report on the effectiveness of these controls. See Item 9A. – “Controls and Procedures” hereof for our evaluation of disclosure controls and procedures. The certifications required by Sections 302 and 906 of the SOX Act also accompany this Form 10-K.

Other Regulatory Matters. We and our subsidiaries and affiliates are subject to numerous examinations by federal and state banking regulators, as well as the SEC, FINRA, NASDAQ Stock Market, and various state insurance and securities regulators.

Corporate Governance. Information with respect to our corporate governance is available on our web site, www.iberiabank.com, and includes:

• Corporate Governance Guidelines

• Nominating and Corporate Governance Committee Charter

• Compensation Committee Charter

• Audit Committee Charter

• Board Risk Committee Charter

• Code of Ethics for directors, officers and other employees

• Code of Ethics for the Chief Executive Officer and Senior Financial Officers

• Chief Executive Officer and Chief Financial Officer Certifications

We intend to disclose any waiver of or substantial amendment to the Codes of Ethics applicable to directors and executive officers on our web site at www.iberiabank.com.

Federal Taxation

We and our subsidiaries are subject to the generally applicable corporate tax provisions of the Internal Revenue Code (the “Code”), and IBERIABANK is subject to certain additional provisions of the Code that apply to financial institutions. We and our subsidiaries file a consolidated federal income tax return on the basis of a fiscal year ending on December 31.

Retained earnings at December 31, 2012 and 2011 included approximately $21.9 million accumulated prior to January 1, 1987 for which no provision for federal income taxes has been made. If this portion of retained earnings is used in the future for any purpose other than to absorb bad debts, it will be added to future taxable income.

The deferred tax liability at December 31, 2012 includes $367.0 million of future deductible temporary differences. Included is $249.4 million related to book deductions for the bad debt reserve that have not been deducted for tax purposes.

State Taxation

Louisiana does not permit the filing of consolidated income tax returns. We are subject to the Louisiana Corporation Income Tax based on our separate Louisiana taxable income, as well as a corporate franchise tax. IBERIABANK is not subject to the Louisiana income or franchise taxes. However, IBERIABANK is subject to the Louisiana Shares Tax which is imposed on the assessed value of our stock. The formula for deriving the assessed value is to calculate 15% of the sum of (a) 20% of our capitalized earnings, plus (b) 80% of our taxable shareholders’ equity, and to subtract from that figure 50% of our real and personal property assessment. Various items may also be subtracted in calculating a company’s capitalized earnings. The portion of the Louisiana shares tax expense calculated on our shareholders’ equity is included in noninterest expense, and the portion calculated on our capitalized earnings is included in income tax expense.

With respect to other states in which we operate, Arkansas generally imposes income tax on financial institutions computed at a rate of 6.5% of net earnings. For the purpose of the 6.5% income tax, net earnings are defined as the net income of the financial institution computed in the manner prescribed for computing the net taxable income for federal corporate income tax purposes, less (i) interest income from obligations of the United States, of any county, municipal or public corporation authority, special district or political subdivision, plus (ii) any deduction for state income taxes.

Florida generally imposes income tax on financial institutions computed at a rate of 5.5% of net earnings. For the purpose of the 5.5% income tax, net earnings are defined as the net income of the financial institution computed in the manner prescribed for computing the net taxable income for federal corporate income tax purposes, less certain modifications defined by Florida law.

Alabama generally imposes income tax on financial institutions computed at a rate of 6.5% of net earnings. For the purpose of the 6.5% income tax, net earnings are defined as the net income of the financial institution computed in the manner prescribed for computing the net taxable income for federal corporate income tax purposes, less certain modifications defined by Alabama law.

Tennessee generally imposes income tax on financial institutions computed at a rate of 6.5% of net earnings. For the purpose of the 6.5% income tax, net earnings are defined as the net income of the financial

14

institution computed in the manner prescribed for computing the net taxable income for federal corporate income tax purposes, less certain modifications defined by Tennessee law.

Item 1A. Risk Factors.

There are risks, many beyond our control, which could cause our results to differ significantly from management’s expectations. Some of these risk factors are described below. Any factor described in this report could, by itself or together with one or more other factors, adversely affect our business, results of operations and/or financial condition. Additional risks and uncertainties not currently known to us or that we currently consider to not be material also may materially and adversely affect us. In assessing these risks, you should also refer to other information disclosed in our SEC filings, including the financial statements and notes thereto.

Risks Associated with IBERIABANK Corporation

The current economic environment and political uncertainty pose significant challenges for us and could adversely affect our financial condition and results of operations.

Although we remain well capitalized and have not suffered from liquidity issues, we are operating in a challenging and uncertain economic environment. Financial institutions continue to be affected by declines in the real estate market and constrained financial markets. We retain direct exposure to the residential and commercial real estate markets, and we could be affected by these events. As of the date of this Report, the U.S. government has been unable to reach agreement on budget reduction measures required by the Budget Control Act of 2011 (the “Budget Act”) passed by Congress. Unless Congress and the Administration take further action, the Budget Act will trigger automatic reductions in both defense and discretionary spending in March 2013 (commonly known as “sequestration”). The resulting automatic across-the-board budget cuts by sequestration would have significant adverse consequences for certain industries. If sequestration is implemented, funding for programs may be reduced, delayed or cancelled, which could have a material adverse effect on the business, financial condition and results of operations for some of our clients. Concerns over sequestration, the United States’ credit rating (which was downgraded by Standard & Poor’s in 2011), the European sovereign debt crisis, and continued high unemployment in the United States, among other economic indicators, have contributed to increased volatility in the capital markets and diminished expectations for the economy.

A return to recessionary conditions could result in increases in our level of non-performing loans and/or reduce demand for our products and services, which would lead to lower revenue, higher loan losses and lower earnings.

Following a national home price peak in mid-2006, falling home prices and sharply reduced sales volumes, along with the collapse of the United States’ subprime mortgage industry in early 2007, significantly contributed to a recession that officially lasted until June 2009, although the effects continued thereafter. Dramatic declines in real estate values and high levels of foreclosures resulted in significant asset write-downs by financial institutions, which have caused many financial institutions to seek additional capital, to merge with other institutions and, in some cases, to fail.

A return of recessionary conditions and/or continued negative developments in the domestic and international credit markets may significantly affect the markets in which we do business, the value of our loans and investments, and our ongoing operations, costs and profitability. Further declines in real estate values and sales volumes and continued high unemployment levels may result in a variety of consequences, including the following:

• increases in loan delinquencies;

• increases in nonperforming and classified assets;

• decreases in demand for our products and services; and

• decreases in the value of collateral securing our loans, especially real estate, which could result in lower recovery amounts on these loans, as well as reduce customers’ borrowing power and our ability to originate future loans.

These negative events may cause us to incur losses and may adversely affect our capital, liquidity, earnings and financial condition.

16

Disruptions in the global financial markets could adversely affect our results of operations and financial condition.

Since mid-2007, global financial markets have suffered substantial disruptions, illiquidity and volatility. These circumstances resulted in significant government assistance to a number of major financial institutions. These events have significantly diminished overall confidence in the financial markets and in financial institutions and have increased the uncertainty we face in managing our business. If these disruptions continue, or other disruptions in the financial markets or the global or our regional economic environment arise, they could have an adverse effect on our future results of operations and financial condition, including our liquidity position, and may affect our ability to access capital.

The Government’s responses to economic conditions may adversely affect our financial performance.

The Federal Reserve Board, or the FRB, in an attempt to help the overall economy, has, among other things, kept interest rates low through its targeted federal funds rate and the purchase of mortgage-backed securities. If the FRB increases the federal funds rate, overall interest rates will likely rise, which may negatively impact the housing markets and the U.S. economic recovery. In addition, deflationary pressures, while possibly lowering our operating costs, could have a significant negative effect on our borrowers, especially our business borrowers, and the values of underlying collateral securing loans, which could negatively affect our financial performance.

The Dodd-Frank Act and related rules and regulations may adversely affect our business, financial condition and results of operations.

The Dodd-Frank Act contains a variety of far-reaching changes and reforms for the financial services industry and directs federal regulatory agencies to study the effects of, and to issue implementing regulations for, these reforms. Many of the provisions of the Dodd-Frank Act could have a direct effect on our performance and, in some cases, impact our ability to conduct business. Examples of these provisions include, but are not limited to:

• Creation of the Financial Stability Oversight Counsel that may recommend to the FRB increasingly strict rules for capital, leverage, liquidity, risk management and other requirements as companies grow in size and complexity;

• Application of the same leverage and risk-based capital requirements that apply to insured depository institutions to most bank holding companies, such as IBERIABANK Corporation;

• Changes to the assessment base used by the FDIC to assess insurance premiums from insured depository institutions and increases to the minimum reserve ratio for the DIF, from 1.15% to not less than 1.35%, with provisions to require institutions with total consolidated assets of $10 billion or more to bear a greater portion of the costs associated with the increasing the DIF’s reserve ratio;

• Repeal of the federal prohibitions on the payment of interest on demand deposits, thereby permitting depository institutions to pay interest on business transaction and other accounts;

• Establishment of the Consumer Financial Protection Bureau, or CFPB, with broad authority to implement and enforce consumer protection regulations, including the authority to prohibit “unfair, deceptive, and abusive practices.” For bank holding companies with $10 billion or more in assets, like IBERIABANK Corporation, the CFPB has the power to examine and enforce compliance with consumer protection laws.

• Implementation of risk retention rules for loans (excluding qualified residential mortgages) that are sold by a bank; and

• Amendment of the Electronic Fund Transfer Act to, among other things, authorize the FRB to issue rules limiting debit-card interchange fees (referred to as the “Durbin Amendment”).

Many of these provisions have already been the subject of proposed and final rulemakings. For example, in response to the Durbin Amendment, the FRB issued final rules that cap debit card interchange fees that may be imposed by financial institutions. Many other provisions, however, remain subject to regulatory rulemaking and implementation, the effects of which are not yet known. The provisions of the Dodd-Frank Act and any rules adopted to implement those provisions, as well as any additional legislative or regulatory changes, may impact the profitability of our business activities, may require that we change certain of our business practices, may materially affect our business model or affect retention of key personnel, may require us to raise additional capital and could expose us to additional cots (including increased compliance costs). These and other changes may also require us to invest significant management attention and resources to make any necessary changes and may adversely affect our ability to conduct our business as previously conducted or our financial condition and results of operations.

We obtain a significant portion of our noninterest revenue through service charges on core deposit accounts. Regulations impacting service charges, changes in customer behavior, and increased competition could reduce our fee income.

A significant portion of our noninterest revenue is derived from service charge income. The largest component of this service charge income is overdraft-related fees. Management anticipates that changes in banking regulations, and in particular the FRB’s rules pertaining to certain overdraft payments on consumer accounts and the FDIC’s Overdraft Payment Programs and Consumer Protection Final Overdraft Payment Supervisory Guidance, will have an adverse impact on our service charge income. Additionally, changes in customer behavior, as well as increased competition from other financial institutions, may result in declines in deposit accounts or in overdraft frequency resulting in a decline in service charge income. A reduction in deposit account fee income could have a material adverse effect on our earnings.

We earn a significant portion of our noninterest revenue through sales of residential mortgages in the secondary market. We are exposed to counterparty credit, market, repurchase and other risks associated with these activities.

Our noninterest revenue attributable to mortgage banking activities has grown significantly in recent years. The Company is exposed to counterparty credit risk in the normal course of these sales activities as well as market risk when engaging in this activity that is greatly impacted by the amount of liquidity in the secondary markets and changes in interest rates. Additionally, the Company retains repurchase risk associated with the sales of these loans that is related to the Company’s residential mortgage loan underwriting and closing practices. Increases in claims under these repurchase or make-whole demands could have a material impact on our ability to continue participating in these types of activities as well as materially impact our financial condition, results of operations, and cash flows.

We may be required to pay significantly higher FDIC deposit insurance premiums or special assessments if the number of bank failures increases, or the cost of resolving failed banks increases, which could adversely affect our earnings.

Market developments have significantly depleted the insurance fund of the FDIC and reduced the ratio of reserves to insured deposits. As a result, we may be required to pay significantly higher premiums or additional special assessments that could adversely affect our earnings. We are generally unable to control the amount of premiums that we are required to pay for FDIC insurance. If there are additional bank or financial institution failures, we may be required to pay even higher FDIC premiums. These announced increases and any future increases or required prepayments in FDIC insurance premiums may materially adversely affect our results of operations.

Repeal of federal prohibitions on payment of interest on demand deposits could increase our interest expense.

All current prohibitions on the payment of interest on demand deposits were repealed as part of the Dodd-Frank Act, effective one year after the date of enactment. As a result, beginning on July 21, 2011, financial institutions commenced offering interest on demand deposits. Our interest expense has increased and our net interest margin has decreased since we began to offer interest on demand deposits to attract additional customers or maintain current customers. Consequently, our business, financial condition or results of operations may be adversely affected.

As with other regulated financial institutions, we may become subject to more stringent regulatory capital requirements that limit our operations and potential growth, and which may result in regulatory action.

IBERIABANK Corporation and IBERIABANK are subject to the comprehensive, consolidated supervision and regulation of the FRB, including risk-based and leverage capital requirements. We must maintain certain risk-based and leverage capital ratios as required by our banking regulators, which can change depending on general economic conditions and IBERIABANK Corporation’s particular condition, risk profile and growth plans. From time to time, regulators implement changes to these regulatory capital adequacy guidelines. If at any time we fail to meet minimum established capital guidelines and/or other regulatory requirements, our financial condition would be materially and adversely affected.

In light of proposed changes to U.S. regulatory capital requirements contained in the Dodd-Frank Act and the evolving international bank capital accords formulated by the Basel Committee and implemented by the FRB, we likely will be required in the future to satisfy additional, more stringent, capital adequacy standards imposed on

18

the industry. Satisfying such capital standards could materially impact us relative to our peers. The ultimate impact of the new capital and liquidity standards on us cannot be determined at this time and depend on a number of factors, including the treatment and implementation by the U.S. banking regulators. These requirements, however, and any other new regulations, could result in lower returns, result in regulatory actions if we were unable to comply with such requirements, and adversely affect our ability to pay dividends or repurchase shares, or to raise capital, including in ways that may adversely affect our financial condition or results of operations. Compliance with current or new capital requirements, including leverage ratios, may limit operations that require the intensive use of capital and could adversely affect our ability to expand or maintain present business levels.

Our recent growth and financial performance will be negatively impacted if we are unable to execute our growth strategy.

Our stated growth strategy is to grow organically and supplement that growth with select acquisitions. Our success depends primarily on generating loans and deposits of acceptable risk and expense. There can be no assurance that we will be successful in continuing our organic, or internal, growth strategy. Our ability to identify appropriate markets for expansion, recruit and retain qualified personnel, and fund growth at a reasonable cost, depends upon prevailing economic conditions, maintenance of sufficient capital, competitive factors, changes in banking laws, and other factors.

Supplementing our internal growth through acquisitions is an important part of our strategic focus. Since 1995, approximately 66% of our asset growth has been through acquisitions, or external growth. Our acquisition efforts focus on select markets and targeted entities. We are in selected markets we consider to be contiguous, or natural extensions, to our current markets. As consolidation of the banking industry continues, the competition for suitable acquisition candidates may increase. We compete with other banking organizations for acquisition opportunities, and many of these competitors have greater financial resources than we do and may be able to pay more for an acquisition than we are able or willing to pay. We also may need additional debt or equity financing in the future to fund acquisitions. We may not be able to obtain additional financing or, if available, it may not be in amounts and on terms acceptable to us. Our issuance of additional securities would dilute existing shareholders’ equity interest in us and may have a dilutive effect on our earnings per share. If we are unable to locate suitable acquisition candidates willing to sell on terms acceptable to us, or we are otherwise unable to obtain additional debt or equity financing necessary for us to continue making acquisitions, and we would be required to find other methods to grow our business, and we may not grow at the same rate we have grown in the past, or at all.

We cannot be certain as to our ability to manage increased levels of assets and liabilities without increased expenses and higher levels of nonperforming assets. We may be required to make additional investments in equipment and personnel to manage higher asset levels and loan balances, which may adversely affect earnings, shareholder returns, and our efficiency ratio. Increases in operating expenses or nonperforming assets may decrease our earnings and the value of our common stock.

In addition to the normal operating challenges inherent in managing a larger financial institution, each of our acquisitions and potential future acquisitions is subject to appropriate regulatory approval. Our regulators may require that we demonstrate that we have appropriately integrated our prior acquisitions, or any future acquisitions we may do, before permitting us to engage in any future material acquisitions.

FDIC-assisted or other acquisition opportunities may not become available, and increased competition could make it more difficult for us to bid on failed bank and other transactions on terms we consider to be acceptable.

A part of our business strategy is to pursue acquisitions, which may include failing banks that are placed into FDIC receivership. The availability of acquisition candidates that meet our strategic objectives can fluctuate, and the FDIC mat not place banks into receivership that meet our strategic objectives. Different from non-FDIC assisted transactions, failed bank transactions typically include loss share arrangements with the FDIC that limit our downside risk on the purchased loan portfolio and, apart from our assumption of deposit liabilities, we have significant discretion as to the non-deposit liabilities that we assume. The terms of loss sharing arrangements may change, making FDIC-assisted transactions less attractive to us. In addition, assets purchased from the FDIC are marked to their fair value and in many cases there is little or no addition to goodwill arising from an FDIC-assisted transaction. In 2012, the number of FDIC failed bank resolutions decreased significantly over the previous year, and consequently, the bidding process for failing banks has become more competitive, and increased competition for such banks has made it more difficult for us to bid on terms we consider acceptable.

19

Like most banking organizations, our business is highly susceptible to credit risk.

As a lender, we are is exposed to the risk that our customers will be unable to repay their loans according to their terms and that the collateral securing the payment of their loans (if any) may not be sufficient to satisfy defaulted loan obligations. Credit losses could have a material adverse effect on our operating results.

As of December 31, 2012, our total loan portfolio was approximately $8.5 billion, or 65% of total assets. At that date, the major components of our loan portfolio included 73% of commercial loans, both real estate and business, 5% of mortgage loans comprised primarily of residential 1-4 family mortgage loans, and 22% of consumer loans. Our credit risk with respect to our consumer installment and commercial loan portfolios relates principally to the general creditworthiness of individuals and businesses within our local market areas. Our credit risk with respect to our residential and commercial real estate mortgage and construction loan portfolios relates principally to the general creditworthiness of individuals and businesses and the value of real estate serving as security for the repayment of the loans. A related risk in connection with loans secured by commercial real estate is the effect of unknown or unexpected environmental contamination, which could make the real estate effectively unmarketable or otherwise significantly reduce its value as security, or could expose us to remediation liabilities as the lender.

Our loan portfolio has and will continue to be affected by the on-going correction in real estate markets, including reduced levels of home sales and declines in the performance of loans.

There continues to be a general slowdown in housing in real estate in some of our market areas, reflecting declining prices and excess inventories. As a result, home builders and commercial developers have shown signs of financial deterioration. A soft residential housing market, increased delinquency rates, and a weakened secondary credit market have affected the overall mortgage industry. We expect the home builder market to continue to be volatile and anticipate continuing pressure on the home builder segment. In addition, many banking institutions, including us, have experienced declines in the performance of other loans, including construction, land development and land loans and commercial loans. We make credit and reserve decisions based on the current conditions of borrowers or projects combined with our expectations for the future. If the slowdown in the housing markets continues, we could experience higher charge-offs and delinquencies beyond that which is provided in the allowance for loan losses. As such, our earnings could be adversely affected through higher than anticipated provisions for loan losses.

Our allowance for credit losses may not be sufficient to cover actual credit losses, which could adversely affect our earnings.

We maintain an allowance for credit losses in an attempt to cover losses inherent in our loan portfolio. Additional loan losses will likely occur in the future and may occur at a rate greater than we have experienced to date.

The determination of the allowance for credit losses, which represents management’s estimate of probable losses inherent in our credit portfolio, involves a high degree of judgment and complexity. Our policy is to establish reserves for estimated losses on delinquent and other problem loans when it is determined that losses are expected to be incurred on such loans. Management’s determination of the adequacy of the allowance is based on various factors, including an evaluation of the portfolio, past loss experience, current economic conditions, the volume and type of lending conducted by us, composition of the portfolio, the amount of our classified assets, seasoning of the loan portfolio, the status of past due principal and interest payments and other relevant factors. Changes in such estimates may have a significant impact on our financial statements. If our assumptions and judgments prove to be incorrect, our current allowance may not be sufficient and adjustments may be necessary to allow for different economic conditions or adverse developments in our loan portfolio. Federal and state regulators also periodically review our allowance for loan losses and may require us to increase our provision for loan losses or recognize further loan charge-offs, based on judgments different than those of our management. Any increase in our allowance for credit losses would have an adverse effect on our operating results and financial condition.

Commercial and commercial real estate loans generally are viewed as having more risk of default than residential real estate loans or other loans or investments. These types of loans also typically are larger than residential real estate loans and other consumer loans. Because the loan portfolio contains a significant number of commercial and commercial real estate loans with relatively large balances, the deterioration of a material amount of these loans may cause a significant increase in nonperforming assets. An increase in nonperforming loans could result in a loss of earnings from these loans, an increase in the provision for credit losses or an increase in loan charge-offs, which would have an adverse impact on our results of operations and financial condition.

20

Changes in interest rates and other factors beyond our control may adversely affect our earnings and financial condition.

Our net income depends to a great extent upon the level of our net interest income. Changes in interest rates can increase or decrease net interest income and net income. Net interest income is the difference between the interest income we earn on loans, investments and other interest-earning assets, and the interest we pay on interest-bearing liabilities, such as deposits and borrowings. Net interest income is affected by changes in market interest rates, because different types of assets and liabilities may react differently, and at different times, to market interest rate changes. When interest-bearing liabilities mature or reprice more quickly than interest-earning assets in a period, an increase in market rates of interest could reduce net interest income. Similarly, when interest-earning assets mature or reprice more quickly than interest-bearing liabilities, falling interest rates could reduce net interest income.

As of December 31, 2012, our interest rate risk model indicated we are fairly balanced over a 12-month time frame. A 100 basis instantaneous and parallel upward shift in interest rates at December 31, 2012, was estimated to increase net interest income over 12 months by approximately 3.8%. Similarly, a 100 basis point decrease in interest rates was expected to decrease net interest income by less than 1%. At December 31, 2012, approximately 51% of our total loan portfolio had fixed interest rates. Eliminating fixed rate loans that mature within a one-year time frame reduces this percentage to 40%. Approximately 71% of our time deposit base will re-price within 12 months from December 31, 2012.

Changes in market interest rates are affected by many factors beyond our control, including inflation, unemployment, the money supply, international events, and events in world financial markets. We attempt to manage our risk from changes in market interest rates by adjusting the rates, maturity, repricing, and balances of the different types of interest-earning assets and interest-bearing liabilities, but interest rate risk management techniques are not exact. As a result, a rapid increase or decrease in interest rates could have an adverse effect on our net interest margin and results of operations. Changes in the market interest rates for types of products and services in our markets also may vary significantly from location to location and over time based upon competition and local or regional economic factors.

If IBERIABANK Corporation or IBERIABANK were unable to borrow funds through access to capital markets, we may not be able to meet the cash flow requirements of our depositors and borrowers, or the operating cash needs to fund corporate expansion and other corporate activities.

Liquidity is the ability to meet cash flow needs on a timely basis at a reasonable cost. IBERIABANK’s liquidity primarily is used to make loans and leases and to repay deposit liabilities as they become due or are demanded by customers. Liquidity policies and limits are established by our board of directors. Management and the Investment Committee regularly monitor the overall liquidity position of IBERIABANK and IBERIABANK Corporation to ensure that various alternative strategies exist to cover unanticipated events that could affect liquidity. Management and the Investment Committee also establish policies and monitor guidelines to diversify IBERIABANK’s funding sources to avoid concentrations in any one market source. Funding sources include Federal funds purchased, securities sold under repurchase agreements, non-core deposits, and short- and long-term debt. IBERIABANK is also a member of the Federal Home Loan Bank, or FHLB System, which provides funding through advances to members that are collateralized with mortgage-related assets.

We maintain a portfolio of securities that can be used as a secondary source of liquidity. There are other sources of liquidity available to us should they be needed. These sources include sales or securitizations of loans, our ability to acquire additional national market, non-core deposits, additional collateralized borrowings such as FHLB advances, the issuance and sale of debt securities, and the issuance and sale of preferred or common securities in public or private offerings. IBERIABANK also can borrow from the FRB’s discount window.

Amounts available under our existing credit facilities as of December 31, 2012, consist of $1.0 billion in FHLB notes and $130.0 million in the form of federal funds and other lines of credit.

If we were unable to access any of these funding sources when needed, we might be unable to meet customers’ needs, which could adversely impact our financial condition, results of operations, cash flows, and level of regulatory-qualifying capital. For further discussion, see Note 14 to the consolidated financial statements in this Report.

21

If our investment in the common stock of the Federal Home Loan Bank of Dallas is classified as other-than-temporarily impaired or as permanently impaired, our earnings and stockholders’ equity could decrease.

We hold FHLB stock to qualify for membership in the Federal Home Loan Bank System and to be eligible to borrow funds under the FHLB advance program. The aggregate cost and fair value of our FHLB common stock as of December 31, 2012 was $16.9 million based on its par value. There is no market for FHLB common stock.

Published reports indicate that certain member banks of the Federal Home Loan Bank System may be subject to accounting rules and asset quality risks that could result in materially lower regulatory capital levels. In an extreme situation, it is possible that the capital of a FHLB could be substantially diminished or reduced to zero. Consequently, we believe that there is a risk that our investment in FHLB common stock could be impaired at some time in the future, and if this occurs, it would cause our earnings and stockholders’ equity to decrease by the after-tax amount of the impairment charge.

Declines in the value of certain investment securities could require write-downs, which would reduce our earnings.

Our securities portfolio includes securities that are subject to declines in value due to negative perceptions about the health of the financial sector in general and the lack of liquidity for securities that are real estate related. A prolonged decline in the value of these or other securities could result in an other-than-temporary impairment write-down, which would reduce our earnings.

We face risks related to our operational, technological and organizational infrastructure.

Our ability to grow and compete is dependent on our ability to build or acquire the necessary operational and technological infrastructure and to manage the cost of such expanded infrastructure. Similar to other large corporations, in our case, operational risk can manifest itself in many ways, such as errors related to failed or inadequate processes, faulty or disabled computer systems, fraud by employees or outside persons and exposure to external events. As discussed below, we are dependent on our operational infrastructure to help manage these risks. In addition, we are heavily dependent on the strength and capability of our technology systems, which we use both to interface with our customers and to manage our internal financial and other systems. Our ability to develop and deliver new products that meet the needs of our existing customers and attract new ones depends on the functionality of our technology systems. Additionally, our ability to run its business in compliance with applicable laws and regulations is dependent on these infrastructures.

We continuously monitor our operational and technological capabilities and make modifications and improvements when we believe it will be cost effective to do so. In some instances, we may build and maintain these capabilities internally. We also outsource some of these functions to third parties. These third parties may experience errors or disruptions that could adversely impact us and over which we may have limited control. We also face risk from the integration of new infrastructure platforms and/or new third party providers of such platforms into our existing businesses.

A failure in our operational systems or infrastructure, or those of third parties, could impair our liquidity, disrupt our businesses, result in the unauthorized disclosure of confidential information, damage our reputation and cause financial losses.

Our businesses are dependent on their ability to process and monitor, on a daily basis, a large number of transactions, many of which are highly complex, across numerous and diverse markets. These transactions, as well as the information technology services we provide to clients, often must adhere to client-specific guidelines, as well as legal and regulatory standards. Due to the breadth of our client base and our geographical reach, developing and maintaining our operational systems and infrastructure is challenging, particularly as a result of rapidly evolving legal and regulatory requirements and technological shifts. Our financial, accounting, data processing or other operating systems and facilities may fail to operate properly or become disabled as a result of events that are wholly or partially beyond our control, such as a spike in transaction volume, cyber attack or other unforeseen catastrophic events, which may adversely affect our ability to process these transactions or provide the impaired services.

In addition, our operations rely on the secure processing, storage and transmission of confidential and other information on our computer systems and networks. Although we take protective measures to maintain the confidentiality, integrity and availability of our and our clients’ information across all geographic and product lines,

22

and endeavor to modify these protective measures as circumstances warrant, the nature of the threats continues to evolve. As a result, our computer systems, software and networks may be vulnerable to unauthorized access, loss or destruction of data (including confidential client information), account takeovers, unavailability of service, computer viruses or other malicious code, cyber attacks and other events that could have an adverse security impact. Despite the defensive measures we take to manage our internal technological and operational infrastructure, these threats may originate externally from third parties such as foreign governments, organized crime and other hackers, and outsource or infrastructure-support providers and application developers, or may originate internally from within our organization. Given the increasingly high volume of our transactions, certain errors may be repeated or compounded before they can be discovered and rectified.

We also face the risk of operational disruption, failure, termination or capacity constraints of any of the third parties that facilitate our business activities, including exchanges, clearing agents, clearing houses or other financial intermediaries. Such parties could also be the source of an attack on, or breach of, our operational systems, data or infrastructure. In addition, as interconnectivity with our clients grows, we increasingly face the risk of operational failure with respect to our clients’ systems.

If one or more of these cyber incidents occurs, it could potentially jeopardize the confidential, proprietary and other information processed and stored in, and transmitted through, our computer systems and networks, or otherwise cause interruptions or malfunctions in our, as well as our clients’ or other third parties’ operations, which could result in damage to our reputation, substantial costs, regulatory penalties and/or client dissatisfaction or loss. Potential costs of a cyber incident may include, but would not be limited to, remediation costs, increased protection costs, lost revenue from the unauthorized use of proprietary information or the loss of current and/or future customers, and litigation.

We maintain an insurance policy which we believe provides sufficient coverage at a manageable expense for an institution of our size and scope with similar technological systems. However, no assurance can be given that this policy would be sufficient to cover all potential financial losses, damages, penalties, including lost revenues, should we experience any one or more of our or a third party’s systems failing or experiencing attack.

We assume certain additional risks associated with credit card lending and debit cards.

Primary risks associated with credit card lending include: (i) credit risk – borrower may hold several credit cards from different issuers, pay only minimum monthly payments and become overextended; (ii) transaction risk – credit card operations are highly automated, have a large transaction volume, are vulnerable to unauthorized access and require strong operational controls; (iii) liquidity risk – credit card obligations require available sources to fund unusual commitments; (iv) strategic risk – each new credit card product and service must be properly evaluated before it is offered; (v) reputation risk – poorly underwritten or performing credit card receivables can affect a bank’s reputation as an underwriter; (vi) re-pricing risk – arises from differences between the timing of interest rate changes and the timing of cash flows; and (vii) compliance risk – consumer laws and regulators, including fair lending and other anti-discrimination laws, rules and regulations affect all aspects of credit card lending.

Across the industry, bad debt and fraud losses in credit and debit cards have risen when compared to historical levels. Reasons for increased losses include changes in underwriting standards, mass marketing of cards in a saturated market, consumer bankruptcies and economic factors, as well as evolving schemes to illegally use cards despite risk management practices employed by us and the card industry. Management of an effective collection process is required to control and minimize such losses.

The loss of certain key personnel could negatively affect our operations.

Although we have employed a significant number of additional executive officers and other key personnel, our success continues to depend in large part on the retention of a limited number of key executive management, lending and other banking personnel. We could undergo a difficult transition period if it were to lose the services of any of these individuals. Our success also depends on the experience of our banking facilities’ managers and lending officers and on their relationships with the customers and communities they serve. The loss of these key persons could negatively impact the affected banking operations. The unexpected loss of key senior managers, or the inability to recruit and retain qualified personnel in the future, could have an adverse effect on our business, financial condition, or operating results.

23

Competition may decrease our growth or profits.

We compete for loans, deposits, title business and investment dollars with other banks and other financial institutions and enterprises, such as securities firms, insurance companies, savings associations, credit unions, mortgage brokers, private lenders and title companies, many of which have substantially greater resources than we do. Credit unions have federal tax exemptions that may allow them to offer lower rates on loans and higher rates on deposits than taxpaying financial institutions such as commercial banks. In addition, non-depository institution competitors are generally not subject to the extensive regulation applicable to institutions, like IBERIABANK, that offer federally insured deposits. Other institutions may have other competitive advantages in particular markets or may be willing to accept lower profit margins on certain products. These differences in resources, regulation, competitive advantages, and business strategy may decrease our net interest margin, may increase our operating costs, and may make it harder for us to compete profitably.

Reputational risk and social factors may impact our results.

Our ability to originate and maintain accounts is highly dependent upon consumer and other external perceptions of our business practices and/or our financial health. Adverse perceptions regarding our business practices and/or our financial health could damage our reputation in both the customer and funding markets, leading to difficulties in generating and maintaining accounts as well as in financing them. Adverse developments with respect to the consumer or other external perceptions regarding the practices of our competitors, or our industry as a whole, may also adversely impact our reputation. In addition, adverse reputational impacts on third parties with whom we have important relationships may also adversely impact our reputation. Adverse impacts on our reputation, or the reputation of our industry, may also result in greater regulatory and/or legislative scrutiny, which may lead to laws or regulations that may change or constrain the manner in which we engage with our customers and the products we offer. Adverse reputational impacts or events may also increase our litigation risk. We carefully monitor internal and external developments for areas of potential reputational risk and have established governance structures to assist in evaluating such risks in our business practices and decisions.

We may be subject to increased litigation which could result in legal liability and damage to our reputation.

IBERIABANK Corporation and IBERIABANK have been named from time to time as defendants in class actions and other litigation relating to our businesses and activities. Litigation may include claims for substantial compensatory or punitive damages or claims for indeterminate amounts of damages. We and our subsidiaries are also involved from time to time in other reviews, investigations and proceedings (both formal and informal) by governmental and self-regulatory agencies regarding our business. These matters also could result in adverse judgments, settlements, fines, penalties, injunctions or other relief.

In addition, in recent years, a number of judicial decisions have upheld the right of borrowers to sue lending institutions on the basis of various evolving legal theories, collectively termed “lender liability.” Generally, lender liability is founded on the premise that a lender has either violated a duty, whether implied or contractual, of good faith and fair dealing owed to the borrower or has assumed a degree of control over the borrower resulting in the creation of a fiduciary duty owed to the borrower or its other creditors or shareholders.

Substantial legal liability or significant regulatory action against us, including our subsidiaries, could materially adversely affect our business, financial condition or results of operations, or cause significant harm to our reputation. Additional information relating to litigation is discussed in Note 20 (“Commitments and Contingencies”) to the consolidated financial statements, and in Part I, Item 3 (“Legal Proceedings”) of this Report.

Changes in government regulations and legislation could limit our future performance and growth.

The banking industry is heavily regulated. We are subject to examination, supervision and comprehensive regulation by various federal and state agencies. Our compliance is costly and restricts certain of our activities. Banking regulations are primarily intended to protect the federal deposit insurance fund and depositors, not shareholders. The burdens imposed by federal and state regulations put banks at a competitive disadvantage compared to less regulated competitors, such as finance companies, mortgage banking companies and leasing companies. Changes in the laws, regulations and regulatory practices affecting the banking industry may increase our costs of doing business or otherwise adversely affect us and create competitive advantages for others. Regulations affecting banks and financial services companies undergo continuous change, and we cannot predict the ultimate effect of these changes, which could have a material adverse effect on our profitability or financial condition. Federal economic and monetary policies may also negatively impact our ability to attract deposits and other funding sources, make loans and investments, and achieve satisfactory interest spreads.

24

The geographic concentration of our markets makes our business highly susceptible to local economic conditions.

Unlike larger organizations that are more geographically diversified, our offices are primarily concentrated in selected markets in Louisiana, Alabama, Arkansas, Florida, Tennessee and Texas. As a result of this geographic concentration, our financial results depend largely upon economic conditions in these market areas. Deterioration in economic conditions in the markets we serve could result in one or more of the following:

• an increase in loan delinquencies;

• an increase in problem assets and foreclosures;

• a decrease in the demand for our products and services; and

• a decrease in the value of collateral for loans, especially real estate, in turn reducing customers’ borrowing power, the value of assets associated with problem loans and collateral coverage.

We face substantial competition and are subject to certain regulatory constraints not applicable to some of our competitors.

We face substantial competition for deposit, and for credit, title and trust relationships, and other financial services and products in the communities we serve. Competing providers include other banks, thrifts and trust companies, insurance companies, mortgage banking operations, credit unions, finance companies, title companies, money market funds and other financial and nonfinancial companies which may offer products functionally equivalent to those offered by us. Competing providers may have greater financial resources than we do and offer services within and outside the market areas we serve. In addition to this challenge of attracting and retaining customers for traditional banking services, our competitors include securities dealers, brokers, mortgage bankers, investment advisors and finance and insurance companies who seek to offer one-stop financial services to their customers that may include services that financial institutions have not been able or allowed to offer to their customers in the past. The increasingly competitive environment is primarily a result of changes in regulation, changes in technology and product delivery systems and the accelerating pace of consolidation among financial service providers. If we are unable to adjust both to increased competition for traditional banking services and changing customer needs and preferences, our financial performance could be adversely affected.

Some of our competitors, including credit unions, are not subject to certain regulatory constraints, such as the Community Reinvestment Act, which, among other things, requires us to implement procedures to make and monitor loans throughout the communities we serve. Complying with these regulatory requirements increases the costs associated with our lending activities, including underwriting expenses, and reduces potential operating profits.

Hurricanes or other adverse weather events could negatively affect our local economies or disrupt our operations, which would have an adverse effect on our business or results of operations.

Like other coastal areas, some of our markets are susceptible to hurricanes and tropical storms. Such weather events can disrupt our operations, result in damage to our properties and negatively affect the local economies in which we operate. We cannot predict whether or to what extent damage that may be caused by future hurricanes or other weather events will affect our operations or the economies in our market areas, but such weather events could result in a decline in loan originations, a decline in the value or destruction of properties securing our loans and an increase in payment delinquencies, foreclosures and loan losses. Our business or results of operations may be adversely affected by these and other negative effects of hurricanes or other significant weather events.

We are exposed to intangible asset risk which could negatively impact our financial results.

In accordance with GAAP, we record assets acquired and liabilities assumed at their fair value, and, as such, acquisitions typically result in recording goodwill. We perform a goodwill evaluation at least annually to test for goodwill impairment. As part of its testing, the Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the Company determines the fair value of a reporting unit is less than its carrying amount using these qualitative factors, the Company then compares the fair value of goodwill with its carrying amount, and then measures impairment loss by comparing the implied fair value of goodwill with the carrying amount of that goodwill. Adverse conditions in our business climate, including a significant decline in future operating cash flows, a significant change in our stock price or market capitalization, or a deviation from our expected growth rate and performance may significantly affect the fair value of our goodwill and may trigger additional impairment losses, which could be materially adverse to our operating results and financial position.

25

We completed such an evaluation for the Company during the fourth quarter of 2012 and concluded that an impairment charge was not necessary for the year ended December 31, 2012. We cannot provide assurance, however, that we will not be required to take an impairment charge in the future. Any impairment charge has an adverse effect on our shareholders’ equity and financial results and could cause a decline in our stock price.

Our reported financial results depend on our management’s selection of accounting methods and certain assumptions and estimates.

Our accounting policies and assumptions are fundamental to our reported financial condition and results of operations. Our management must exercise judgment in selecting and applying many of these accounting policies and methods so they comply with generally accepted accounting principles and reflect management’s judgment of the most appropriate manner to report our financial condition and results. Our management must also exercise judgment in selecting assumptions and estimates inherent in deriving certain financial statement line items. In some cases, management must select the accounting policy, method, assumption and/or estimate to apply from two or more alternatives, any of which may be reasonable under the circumstances, yet may result in our reporting materially different results than would have been reported under a different alternative.

Risks Related to FDIC-assisted Transactions and Other Bank Acquisitions

The success of FDIC-assisted transactions and other bank acquisitions will depend on a number of uncertain factors.

The success of our FDIC-assisted transactions and other bank acquisitions depends on a number of factors, including, without limitation:

• our ability to integrate the branches acquired into IBERIABANK’s current operations;

• our ability to limit the outflow of deposits held by our new customers in the acquired branches and to successfully retain and manage interest-earning assets (i.e., loans) acquired;

• our ability to attract new deposits and to generate new interest-earning assets in the geographic areas previously served by the acquired branches;

• our ability to effectively compete in new markets in which we did not previously have a presence;

• our success in deploying the cash received in these transactions into assets bearing sufficiently high yields without incurring unacceptable credit or interest rate risk;

• our ability to control the incremental non-interest expense from the acquired branches in a manner that enables us to maintain a favorable overall efficiency ratio;

• our ability to retain and attract the appropriate personnel to staff the acquired branches; and

• our ability to earn acceptable levels of interest and non-interest income, including fee income, from the acquired branches.

In any acquisition involving a financial institution, particularly one involving the transfer of a large number of bank branches, there may be business and service changes and disruptions that result in the loss of customers or cause customers to close their accounts and move their business to competing financial institutions. Integration of such acquired branches is an operation of substantial size and expense, and may be impacted by general market and economic conditions or government actions affecting the financial industry generally. Integration efforts also are likely to divert our management’s attention and resources. No assurance can be given that we will be able to integrate these acquired branches successfully, and the integration process could result in the loss of key employees, the disruption of ongoing business, or inconsistencies in standards, controls, procedures and policies that adversely affect our ability to maintain relationships with clients, customers, depositors and employees or to achieve the anticipated benefits of FDIC-assisted transactions and other bank acquisitions. We may also encounter unexpected difficulties or costs during the integration that could adversely affect our earnings and financial condition, perhaps materially. Additionally, no assurance can be given that the operation of acquired branches will not adversely affect our existing profitability, that we will be able to achieve results in the future similar to those achieved by our existing banking business, that we will be able to compete effectively in the market areas currently served by the acquired branches, or that we will be able to manage any growth resulting from FDIC-assisted transactions and/or bank acquisitions effectively.

Our ability to grow acquired branches following these transactions depends in part on our ability to retain certain key branch personnel we expect to hire and/or retain in connection with these transactions. We believe that

26

the ties these employees have in the local banking markets previously served by their acquired branches are vital to our ability to maintain our relationships with existing customers and to generate new business in these markets. Our failure to hire or retain these employees could adversely affect the success of these transactions and our future growth.

Changes in national and local economic conditions could lead to changes in the expectations of the amount and timing of losses and higher loan charge-offs in connection with acquisition transactions. Some or all of such losses and charge-offs in FDIC assisted transactions may not be supported by the related loss sharing agreements with the FDIC.

We have acquired significant loan portfolios through FDIC-assisted transactions and other bank acquisitions. Although these loan portfolios were initially accounted for at fair value, there is no assurance that the loans we acquired will not become impaired in the future, which may result in additional charge-offs to this portfolio. The fluctuations in national, regional and local economic conditions, including those related to local residential, commercial real estate and construction markets, may increase the level of charge-offs that we make to our loan portfolio, and, consequently, reduce our net income, and may also increase the level of charge-offs on our loan portfolio that we have acquired in our acquisitions and correspondingly reduce our net income. These fluctuations are not predictable, cannot be controlled and may have a material adverse impact on our operations and financial condition even if other favorable events occur.

Although in our FDIC-assisted transactions we have entered into loss sharing agreements with the FDIC which provide that a significant portion of losses related to specified loan portfolios that we have acquired in connection with the FDIC-assisted transactions will be borne by the FDIC, we are not fully protected for all losses resulting from charge-offs with respect to those specified loan portfolios. The loss sharing agreements have limited terms; therefore, any charge-off of related losses we experience after the term of the loss sharing agreements will not be reimbursed by the FDIC and will negatively impact our net income. Additionally, the terms of the agreements require us to remit to the FDIC recoveries on prior loss claims which could impact our net income. The loss sharing agreements also impose standard requirements on us which must be satisfied in order to retain loss share protections.

Deposit and loan run-off rates could exceed the rates we have projected in connection with our planning for the FDIC-assisted transactions and other bank acquisitions and the integration of the acquired branches.

Deposit run-off could be higher than our assumptions. As part of acquisition transactions, it is necessary for us to convert customer loan and deposit data from the failed banks’ data processing systems to our data processing system. Delays or errors in the conversion process could adversely affect customer relationships, increase run-off of deposit and loan customers and result in unexpected charges and costs. Similarly, run-off could increase if we are not able to service in a cost-effective manner particular loan or deposit products with special features previously offered by the failed or target banks. Any increase in run-off rates could adversely affect our ability to stimulate growth in such acquired branches, our liquidity, and our results of operations.

Risks About Our Common Stock

We cannot guarantee that we will pay dividends to shareholders in the future.

Cash available to pay dividends to our shareholders is derived primarily, if not entirely, from dividends paid to us from IBERIABANK. The ability of IBERIABANK to pay dividends to us, as well as our ability to pay dividends to its shareholders, are limited by regulatory and legal restrictions and the need to maintain sufficient consolidated capital. We may also decide to limit the payment of dividends even when we have the legal ability to pay them in order to retain earnings for use in our business. Further, any lenders making loans to us may impose financial covenants that may be more restrictive than regulatory requirements with respect to the payment of dividends. For instance, we are prohibited from paying dividends on our common stock if the required payments on our subordinated debentures have not been made. There can be no assurance of whether or when we may pay dividends in the future.

The trading history of our common stock is characterized by modest trading volume. The value of your investment may be subject to sudden decreases due to the volatility of the price of our common stock.

Our common stock trades on NASDAQ Global Select Market. During 2012, the average daily trading volume of our common stock was approximately 156,700 shares. We cannot predict the extent to which investor interest in us will lead to a more active trading market in our common stock or how much more liquid that market might become. A public trading market having the desired characteristics of depth, liquidity and orderliness

27

depends upon the presence in the marketplace of willing buyers and sellers of our common stock at any given time, which presence is dependent upon the individual decisions of investors, over which we have no control.

The market price of our common stock may be highly volatile and subject to wide fluctuations in response to numerous factors, including, but not limited to, the factors discussed in other risk factors and the following:

• actual or anticipated fluctuations in operating results;

• changes in interest rates;

• changes in the legal or regulatory environment in which we operate;

• press releases, announcements or publicity relating to us or our competitors or relating to trends in our industry;

• changes in expectations as to our future financial performance, including financial estimates or recommendations by securities analysts and investors;

• future sales of our common stock;

• changes in economic conditions in our marketplace, general conditions in the U.S. economy, financial markets or the banking industry; and

• other developments affecting our competitors or us.

These factors may adversely affect the trading price of our common stock, regardless of our actual operating performance, and could prevent our shareholders from selling common stock at or above the public offering price. In addition, the stock markets, from time to time, experience extreme price and volume fluctuations that may be unrelated or disproportionate to the operating performance of companies. These broad fluctuations may adversely affect the market price of our common stock, regardless of our trading performance.

In the past, shareholders often have brought securities class action litigation against a company following periods of volatility in the market price of their securities. We may be the target of similar litigation in the future, which could result in substantial costs and divert management’s attention and resources.

Sales of a significant number of shares of our common stock in the public markets, or the perception of such sales, could depress the market price of our common stock.

Sales of a substantial number of shares of our common stock in the public markets and the availability of those shares for sale could adversely affect the market price of our common stock. In addition, future issuances of equity securities, including pursuant to the exercise of outstanding stock options, could dilute the interests of our existing shareholders, and could cause the market price of our common stock to decline. We may issue such additional equity or convertible securities to raise additional capital. The issuance of any additional shares of common or preferred stock or convertible securities could be substantially dilutive to holders of our common stock. Moreover, to the extent that we issue restricted stock units, phantom shares, stock appreciation rights, options or warrants to purchase our common stock in the future and those stock appreciation rights, options or warrants are exercised or as the restricted stock units vest, our shareholders may experience further dilution. Holders of our shares of common stock have no preemptive rights that entitle holders to purchase their pro rata share of any offering of shares of any class or series and, therefore, such sales or offerings could result in increased dilution to our shareholders. We cannot predict the effect that future sales of our common stock would have on the market price of our common stock.

We may issue debt and equity securities or securities convertible into equity securities, any of which may be senior to our common stock as to distributions and in liquidation, which could negatively affect the value of our common stock.

In the future, we may attempt to increase our capital resources by entering into debt or debt-like financing that is unsecured or secured by all or up to all of our assets, or by issuing additional debt or equity securities, which could include issuances of secured or unsecured commercial paper, medium-term notes, senior notes, subordinated notes, preferred stock or securities convertible into or exchangeable for equity securities. In the event of our liquidation, our lenders and holders of our debt and preferred securities would receive a distribution of our available assets before distributions to the holders of our common stock. Because our decision to incur debt and issue securities in our future offerings will depend on market conditions and other factors beyond our control, we cannot predict or estimate the amount, timing or nature of our future offerings and debt financings. Further, market conditions could require us to accept less favorable terms for the issuance of our securities in the future.

28

Our management has broad discretion over the use of proceeds from equity offerings.

Our management has significant flexibility in applying the proceeds that we receive from equity offerings. Although we have indicated our intent to use the proceeds from recent offerings for general corporate purposes, including future acquisitions, our working capital needs, and our investments in our subsidiaries, our management retains significant discretion with respect to uses of proceeds. The proceeds of our offerings may be used in a manner that does not generate a favorable return for us. We may use the proceeds to fund future acquisitions of other businesses. In addition, if we use the funds to acquire other businesses, there can be no assurance that any business we acquire would be successfully integrated into our operations or otherwise perform as expected.

We may issue additional securities, which could dilute your ownership percentage.

In many situations, our board of directors has the authority, without any vote of our shareholders, to issue shares of our authorized but unissued stock, including shares authorized and unissued under our stock option plans. In the future, we may issue additional securities, through public or private offerings, to raise additional capital or finance acquisitions. Moreover, to the extent we issue restricted stock units, stock appreciation rights, options or warrants to purchase our common stock in the future and those stock appreciation rights, options or warrants are exercised or as the restricted stock units vest, our shareholders may experience further dilution. Any such issuance would dilute the ownership of current holders of our common stock.

Item 1B. Unresolved Staff Comments.

None.

Item 2. Properties.

As of December 31, 2012, we operated 278 combined offices, including 184 bank branch offices in Louisiana, Arkansas, Alabama, Florida, Texas, and Tennessee, 21 title insurance offices in Arkansas and Louisiana, and had mortgage representatives in 62 locations in twelve states. Office locations are either owned or leased. For offices in premises leased by us or our subsidiaries, rent expense totaled $10.6 million in 2012. During 2012, we and our subsidiaries received $1.6 million in rental income for space leased to others. At December 31, 2012, there were no significant encumbrances on the offices, equipment and other operational facilities owned by us and our subsidiaries.

Additional information on our premises is provided in Note 9 to the Consolidated Financial Statements incorporated herein by reference.

Item 3. Legal Proceedings.

The nature of the business of IBKC’s banking and other subsidiaries ordinarily results in a certain amount of claims, litigation, investigations and legal and administrative cases and proceedings, all of which are considered incidental to the normal conduct of business. Some of these claims are against entities or assets of which IBKC is a successor or acquired in business acquisitions, and certain of these claims will be covered by loss sharing agreements with the FDIC. For additional information, see Note 5 to the consolidated financial statements. IBKC believes it has meritorious defenses to the claims asserted against it in its currently outstanding legal proceedings and, with respect to such legal proceedings, intends to continue to defend itself vigorously, litigating or settling cases according to management’s judgment as to what is in the best interest of IBKC and its shareholders.

IBKC assesses its liabilities and contingencies in connection with outstanding legal proceedings utilizing the latest information available. Where it is probable that IBKC will incur a loss and the amount of the loss can be reasonably estimated, IBKC records a liability in its consolidated financial statements. These legal reserves may be increased or decreased to reflect any relevant developments on a quarterly basis. Where a loss is not probable or the amount of loss is not estimable, IBKC does not accrue legal reserves. While the outcome of legal proceedings is inherently uncertain, based on information currently available, advice of counsel and available insurance coverage, IBKC’s management believes that it has established adequate legal reserves. Any liabilities arising from pending legal proceedings are not expected to have a material adverse effect on IBKC’s consolidated financial position, consolidated results of operations or consolidated cash flows. However, in the event of unexpected future developments, it is possible that the ultimate resolution of these matters, if unfavorable, may be material to IBKC’s consolidated financial position, consolidated results of operations or consolidated cash flows.

Share Repurchases

Share repurchases may be made from time to time, on the open market or in privately negotiated transactions, at the discretion of the management of the Company, after the Board of Directors authorizes a

32

repurchase program. The approved share repurchase program does not obligate the Company to repurchase any dollar amount or number of shares, and the program may be extended, modified, suspended, or discontinued at any time. Stock repurchases generally are affected through open market purchases, and may be made through unsolicited negotiated transactions. The timing of these repurchases will depend on market conditions and other requirements.

In August of 2011, the Board of Directors authorized the repurchase of up to 900,000 shares of common stock, and in October authorized the repurchase of an additional 900,000 shares of common stock.

The following table details these purchases during 2012. Information is based on the settlement date of the transactions. The average price paid per share includes commissions paid. No shares were repurchased during the months not presented in the table.

Restrictions on Dividends

Holders of the Company’s common stock are only entitled to receive such dividends as the Board of Directors may declare out of funds legally available for such payments. Furthermore, holders of the common stock are subject to priority dividend rights of any holders of preferred stock then outstanding. At December 31, 2012, no shares of preferred stock were issued and outstanding.

In addition, the terms of the Company’s outstanding junior subordinated debt securities prohibit it from declaring or paying any dividends or distributions on outstanding capital stock, or purchasing, acquiring, or making a liquidation payment on such stock, if the Company has elected to defer interest payments on such debt.

Item 9A. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

As required by Rule 13a-15 under the Securities Exchange Act of 1934 (the “Exchange Act”), we performed an evaluation of the effectiveness of our disclosure controls and procedures as of December 31, 2012. The evaluation was carried out under the supervision, and with the participation of, the Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”). Based on that evaluation, the CEO and CFO have concluded that our disclosure controls and procedures were effective as of the period covered by this Report in alerting them in a timely manner to material information required to be disclosed by us in reports that we file or submit under the Exchange Act.

In addition, we reviewed our financial reporting internal controls. During the last fiscal quarter, we enhanced the controls in our financial statement preparation process by adding an additional level of management review to selected statements and footnotes. We believe these enhancements led to the detection and remediation of a material weakness in internal control over financial reporting that resulted in restatement of our consolidated statement of cash flows for the years ended December 31, 2011 and 2010 and year-to-date periods ended March 31, 2012, June 30, 2012, and September 30, 2012, as more fully described in Note 1 and Note 26 to the consolidated financial statements. The Company has concluded the material weakness has been remediated and does not result in a material weakness in the Company’s internal controls over financial reporting as of December 31, 2012. Excluding this enhancement, there were no significant other changes in our internal control over financial reporting during the last fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. Management’s Annual Report on Internal Control over Financial Reporting, and the attestation report of the independent registered public accounting firm are included in Exhibit 13 and are incorporated by reference herein.

Management Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Our internal control over financial reporting was designed under the supervision of the CEO and CFO to provide reasonable assurance regarding the reliability of financial reporting and the preparation of published financial statements in accordance with U.S. GAAP.

Management assessed the effectiveness of internal control over financial reporting as of December 31, 2012. In making this assessment, it used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control—Integrated Framework. Based on our assessment, we believe that, as of December 31, 2012, our internal control over financial reporting was effective based on those criteria.

The effectiveness of our internal control over financial reporting as of December 31, 2012 was audited by Ernst & Young LLP, an independent registered public accounting firm, as stated in their report appearing in Exhibit 13 to this report.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis is intended to assist readers in understanding the consolidated financial condition and results of operations of IBERIABANK Corporation and its wholly owned subsidiaries (collectively, the “Company”), as of December 31, 2012 and 2011 and for the years ended December 31, 2012 through 2010. This discussion should be read in conjunction with the audited consolidated financial statements, accompanying footnotes and supplemental financial data included herein.

To the extent that statements in this Report relate to future plans, objectives, financial results or performance of the Company, these statements are deemed to be forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Such statements, which are based on management’s current information, estimates and assumptions and the current economic environment, are generally identified by the use of the words “plan”, “believe”, “expect”, “intend”, “anticipate”, “estimate”, “project” or similar expressions. The Company’s actual strategies and results in future periods may differ materially from those currently expected due to various risks and uncertainties.

Factors that may cause actual results to differ materially from these forward-looking statements are discussed in the Company’s Annual Report on Form 10-K and other filings with the Securities and Exchange Commission (the “SEC”), available at the SEC’s website, http://www.sec.gov, and the Company’s website, http://www.iberiabank.com, under the heading “Investor Information.” All information in this discussion is as of the date of this Report. The Company undertakes no duty to update any forward-looking statement to conform the statement to actual results or changes in the Company’s expectations.

Included in this discussion and analysis are descriptions of the composition, performance, and credit quality of the Company’s loan portfolio. The Company has three descriptions of loans that are used to categorize the portfolio into its distinct risks and rewards to consolidated financial statements. “Acquired loans” refer to all loans acquired in a business combination. Because of the loss protection provided by the FDIC, the risks of the loans and foreclosed real estate acquired in the CapitalSouth Bank (“CSB”), Orion Bank (“Orion”), Century Bank (“Century”), and Sterling Bank (“Sterling”) acquisitions, which are covered by loss share agreements with the Federal Deposit Insurance Corporation (the “FDIC”), are significantly different from those assets not similarly covered. Accordingly, the Company reports loans subject to the loss share agreements as “covered loans” in the information below and loans that are not subject to the loss share agreement as “non-covered loans.” The subset of acquired loans that is not subject to loss share agreements are referred to as “non-covered acquired loans.” Loans that are neither subject to loss share agreements nor acquired in a business combination are referred to as “legacy loans” or “organic loans.”

EXECUTIVE OVERVIEW

The Company offers commercial and retail banking products and services to customers in locations in six states through IBERIABANK. The Company also operates mortgage production offices in 12 states through IBERIABANK’s subsidiary, IBERIABANK Mortgage Company (“IMC”), and offers a full line of title insurance and closing services throughout Arkansas and Louisiana through Lenders Title Company (“LTC”) and its subsidiaries. IBERIA Capital Partners L.L.C. (“ICP”) provides equity research, institutional sales and trading, and corporate finance services. IB Aircraft Holdings, LLC owns a fractional share of an aircraft used by management of the Company and its subsidiaries. IBERIA Asset Management Inc. (“IAM”) provides wealth management and trust services for commercial and private banking clients. IBERIA CDE, L.L.C. is engaged in the purchase of tax credits.

The Company’s focus is that of a high performing institution. Management believes that improvement in core earnings drives shareholder value, and the Company has adopted a mission statement that is designed to provide guidance for our management, associates and Board of Directors regarding the sense of purpose and direction of the Company. We are shareholder- and client-focused, expect high performance from our associates, believe in a strong sense of community and strive to make the Company a great place to work.

During 2012, the Company continued to execute its business model successfully, as evidenced by solid organic loan and deposit growth during the year, despite the challenges of the current operating environment, which include enhanced regulatory scrutiny and continued interest rate pressure. The Company also continued to develop its noninterest revenue streams, particularly from its wealth management and mortgage production subsidiaries. The Company believes it remains well positioned for future growth opportunities, as evidenced by the strength in its liquidity, core funding, and capitalization levels.

In the past year, the Company continued to experience substantial growth in both income statement and balance sheet metrics. These areas of growth were driven by investments in markets and business lines. For the year ended December 31, 2012 these investments contributed to net interest income growth of $43.5 million to $381.8 million and noninterest income growth of $44.1 million to $176.0 million. Legacy loans grew by $1.4 billion, or 26.1% during 2012 to $6.7 billion at December 31, 2012 and total deposits grew by $1.5 billion, or 15.7%, to $10.7 billion for and as of the same periods, while acquired loans decreased by $45.8 million. The mix of deposits shifted significantly to noninterest-bearing, which represented 18.3% of total deposits as of December 31, 2012, up from 16.0% from the prior year end. Throughout 2012, the Company’s liquidity, both on balance sheet and off balance sheet, continued to be favorable, exhibited by liquidity ratios that exceeded peer levels. The Company’s cash position continued to grow in 2012, and the Company has funding availability from the Federal Home Loan Bank (the “FHLB”) and correspondent bank lines to continue to meet cash flow needs. Additionally, its capital ratios were considerably in excess of “well capitalized” from a regulatory perspective and above peer levels, and its primary risk measures remained favorable. All of these factors allowed the Company to maintain its strategic positioning within the challenging banking environment and provided a strong base from which to continue to grow its balance sheet and remain positioned to provide anticipated increases in shareholder value in 2013.

During 2012, the Company’s mortgage origination and title businesses delivered record years for the Company, and helped to drive noninterest income growth over 2011. Specifically, mortgage origination volume and an improved margin on the sales of these loans led to a 72.8% increase in mortgage income over the previous year. Title income was $2.9 million, or 16.3%, higher than in 2011. The Company’s trust and wealth management businesses also began to see the Company’s investment in these businesses pay off, as broker commissions increased 31.5% over 2011.

During the past year, noninterest income increased as the Company began realizing better returns on its investments as compared to prior years. Noninterest expense also increased. On a basis consistent with generally accepted accounting principles (“GAAP”), noninterest expense was $432.2 million for the year ended December 31, 2012, an increase of $58.5 million versus the prior year. Noninterest expense, excluding non-operating items (“non-GAAP”, see table 4 below) was $418.2 million for the same period, which represented an increase of $65.8 million versus the prior year. The increase in operating noninterest expense was a result of higher employee-related expenses as the Company increased headcount during 2012, both from the Florida Gulf acquisition and from strategic hires to continue growing its business lines. Noninterest expense was also driven higher in 2012 by the full weight of the OMNI and Cameron acquisitions, as well as five months of expenses from the branches acquired from Florida Gulf. On a GAAP basis, noninterest expense increased due to the factors contributing to the increase in non-GAAP noninterest expense, but was offset by a reduction in merger-related expenses of $10.9 million. The reduction in merger-related expenses was a result of an improvement in the efficiency of merger-related activity, including system conversion costs, but was also the result of one less acquisition than in 2011.

The provision for credit losses decreased $5.2 million due to an improvement in asset quality in the legacy portfolio over the past 12 months, but was partially offset by additional expected losses in the acquired loan and covered loan portfolios.

All of these factors led net income available to common shareholders for the year ended December 31, 2012 to increase $22.9 million to $76.4 million or $2.59 per diluted share. Pre-provision operating earnings (non-GAAP) increased $13.1 million to $95.1 million or $3.19 on a per share basis.

During 2011, the Company grew its balance sheet and increased its overall capital position through acquisitions, the opening of new branch locations, and organic growth at many of the Company’s existing branches. The Company completed the OMNI and Cameron acquisitions on May 31, 2011 and the FTC asset acquisition on June 14, 2011. In addition, the Company increased its small business lending efforts with the addition of personnel experienced in successfully developing and implementing credit programs focused on

small businesses. The Company also diversified its revenue stream through expansion of its fee-based businesses, primarily IMC, LTC, and ICP.

Acquisition Activity during 2012

Over the past 13 years, the Company’s growth has included growth from targeted acquisitions the Company determined would provide additional shareholder value to existing shareholders and be a strong strategic fit with the Company.

During the third quarter of 2012, the Company completed the acquisition of Florida Gulf, the holding company of Florida Gulf Bank, headquartered in Fort Myers, Florida. The acquisition expanded the Company’s presence in southwest Florida. The acquisition was consummated after the close of business on July 31, 2012.

A summary of the major categories of assets acquired and liabilities assumed (all recorded at fair value at the time of acquisition), as well as the goodwill created, in the Florida Gulf acquisition is shown in the following table.

As part of the Florida Gulf acquisition, the Company issued 754,334 shares of its common stock during the third quarter of 2012, resulting in additional equity of $37.2 million. Other equity consideration included the issuance of stock options to purchase 32,863 shares of the Company’s common stock for a fair value of $0.7 million. Non-equity consideration included in the acquisition totaled $7.5 million, which included cash paid for fractional shares, severance payments under change in control agreements, and contingent consideration. Of the $7.5 million, $4.6 million was paid in cash during the year, with the difference recorded as an adjustment to net assets acquired. See Note 4 to the consolidated financial statements for additional information on the acquisitions.

Other Acquisition Activity

In addition to the Florida Gulf acquisition completed during 2012, the Company has been an active acquirer over the previous nine years. From 2003 through 2011, the Company completed the following acquisitions, presented with intangible assets created and selected assets and liabilities acquired for each acquisition:

Balance Sheet Position and Results of Operations

During 2012, the Company’s income available to common shareholders totaled $76.4 million, or $2.59 per share on a diluted basis, a 42.7% increase compared to the $53.5 million earned in 2011. On a per share basis, this represents an increase of 38.5% from the $1.87 per diluted share earned in 2011. On an operating basis (non-GAAP), per share earnings increased $0.47 to $2.74 in 2012. Primary drivers of the increase in earnings over the prior year include the earnings from the net assets acquired from Florida Gulf and a decrease in merger-related noninterest expenses. Key components of the Company’s 2012 performance are summarized below.

• Total assets at December 31, 2012 were $13.1 billion, up $1.4 million, or 11.7%, from December 31, 2011. The increase was primarily the result of the Florida Gulf acquisition, which added $372.1 million in assets. Excluding the acquired assets, growth in the Company’s loan portfolio was a result of organic growth in many of the Company’s markets. The Company’s balance sheet growth was affected by a decrease in both the Company’s loan portfolio covered by FDIC reimbursement agreements and the related receipt of funds from the FDIC.

• Total loans at December 31, 2012 were $8.5 billion, an increase of $1.1 billion, or 15.0%, from $7.4 billion at December 31, 2011. Loan growth during 2012 was driven by an increase in non-covered loans. Total non-covered loans increased $1.4 billion, or 22.3%, during 2012. $215.8 million, or 16.0%, of that growth was from the Florida Gulf acquisition. Covered loans decreased $241.7 million, or 18.1%, from December 31, 2011, as covered loans were paid down or charged off and submitted for reimbursement.

• Total customer deposits increased $1.5 billion, or 15.7%, from $9.3 billion at December 31, 2011 to $10.7 billion at December 31, 2012. By product type, the Company’s noninterest-bearing deposits increased $482.6 million, or 32.5%, while interest-bearing deposits increased $976.7 million, or 12.5%. Acquired deposits from Florida Gulf accounted for 19.6% of the total growth. The increase in the Company’s interest-bearing demand deposits was partially offset by the decrease in time deposits of 15.4% from December 31, 2011. The decline in time deposits is the result of the Company’s effort to prudently manage the profitability of the deposit base with liquidity needs. Although deposit competition remained intense throughout 2012, the Company was able to generate strong growth across its many other deposit products. Organic deposit growth was driven by growth in the Company’s Houston, Texas, New Orleans, Louisiana, Lafayette, Louisiana, and Baton Rouge, Louisiana markets.

• Shareholders’ equity increased $47.2 million, or 3.2%, to $1.5 billion at December 31, 2012. The increase was the result of net income of $76.4 million and additional common stock issued in the Florida Gulf acquisition of $39.2 million. Growth in shareholders’ equity was offset partially by $40.1 million in dividends paid on the Company’s common stock during the period and treasury share repurchases of $40.4 million.

• Net interest income increased $43.5 million, or 12.9%, in 2012 when compared to 2011. This increase was attributable to a $24.9 million increase in interest income and an $18.6 million, or 22.7%, decrease in interest expense. Interest income was positively affected by a $1.1 billion increase in average earning assets, due to both the inclusion of Florida Gulf earning assets in the current year and the organic growth in loans since December 2011. The increase in income due to growth in the Company’s earning asset base was offset by a 19 basis point decline in the yield earned on these assets. Compared to 2011, the Company’s net interest margin ratio on a tax-equivalent basis increased to 3.58% from 3.51% due to changes in the volume and mix of the Company’s assets and liabilities and rate decreases driven by federal funds, Treasury, and other Company borrowing rate decreases during 2012.

• Noninterest income increased $44.1 million, or 33.5%, in 2012 when compared to the same 2011 period. The increase was primarily driven by a $32.9 million increase in mortgage income. Increases of $2.9 million in title insurance income and $3.2 million in broker commissions also contributed to the total increase from 2011.

• Additional expenses incurred due to the expanded size of the Company drove the increase in noninterest expenses in 2012 over 2011. Noninterest expense in 2012 was also higher as a result of various projects designed to enhance the Company’s operational efficiency and improve profitability that led to elevated levels of professional fees. Noninterest expense increased $58.5 million, or 15.6%, when compared to 2011. The increase in total noninterest expense was attributable to higher salary and employee benefit costs of $40.0 million, as well as increased occupancy, equipment, and other branch expenses resulting from the Company’s expanded footprint. In addition to personnel and other costs related to the expanding size of the Company, noninterest expenses were driven higher in 2012 by professional services expenses, as well as increased data processing expenses as the Company expands its business operations.

• During the second, third, and fourth quarters of 2012, the Company incurred costs associated with the acquisition of Florida Gulf, conversions, branch closures, severance, and process improvements that affected the Company’s net income and per-share earnings for the year ended December 31, 2012. The Company incurred these costs to improve its long-term operating efficiency, risk-adjusted profitability, and long-term growth prospects. The Company also announced plans to consolidate and enhance underperforming branches, elevate sales effectiveness and improve efficiency. The total cost of these initiatives affected total noninterest expense and is discussed in further detail in the “Noninterest expense” section below.

• The Company recorded a provision for credit losses of $20.7 million during 2012, 20.1% lower than the $25.9 million provision recorded in 2011. The provision in 2012 was primarily the result of loan growth from December 31, 2011 and provisions recorded on the Company’s covered and acquired loan portfolios, as the Company had legacy net charge-offs of only $4.5 million during 2012. The improvement in asset quality from December 31, 2011 has offset the need for a higher allowance for credit losses as a result of loan growth in 2012. As of December 31, 2012, the allowance for credit losses as a percent of total loans was 2.96%, compared to 2.62% at December 31, 2011.

• The Company paid a quarterly cash dividend of $0.34 per common share in each quarter of 2012, consistent with the dividends paid in 2011. The Company’s dividend payout ratio to common shareholders was 52.5% and 73.6% for the years ended December 31, 2012 and 2011, respectively.

This discussion and analysis contains financial information determined by methods other than in accordance with GAAP. The Company’s management uses these non-GAAP financial measures in their analysis of the Company’s performance. These measures typically adjust GAAP performance measures to exclude the effects of the amortization of intangibles and include the tax benefit associated with revenue items that are tax-exempt, as well as adjust income available to common shareholders for certain significant activities or transactions that, in management’s opinion, distort period-to-period comparisons of the Company’s performance. Since the presentation of these GAAP performance measures and their impact differ between companies, management believes presentations of these non-GAAP financial measures provide useful supplemental information that is essential to a proper understanding of the operating results of the Company’s core businesses. These non-GAAP disclosures should not be viewed as a substitute for operating results determined in accordance with GAAP, nor are they necessarily comparable to non-GAAP performance measures that may be presented by other companies. Reconciliations of GAAP to non-GAAP disclosures are included in the table below.

APPLICATION OF CRITICAL ACCOUNTING POLICIES AND ESTIMATES

In preparing financial reports, management is required to apply significant judgment to various accounting, reporting and disclosure matters. Management must use assumptions and estimates to apply these principles where actual measurement is not possible or practical. The accounting principles and methods used by the Company conform with accounting principles generally accepted in the United States and general bank accounting practices. Estimates and assumptions most significant to the Company relate primarily to the calculation of the allowance for credit losses, the accounting for acquired loans and the related FDIC loss share receivable on covered loans, the valuation of goodwill, intangible assets and other purchase accounting adjustments, and the valuation of share-based compensation. These significant estimates and assumptions are summarized in the following discussion and are further analyzed in the footnotes to the consolidated financial statements.

Allowance for Credit Losses

The determination of the allowance for credit losses has two components, the allowance for legacy credit losses and the allowance for acquired credit losses. The allowance for acquired credit losses is calculated as described in the Accounting for Acquired Loans and Related FDIC Loss Share Receivable section below. The allowance for legacy credit losses, which represents management’s estimate of probable losses inherent in the Company’s loan portfolio, involves a high degree of judgment and complexity. The Company’s policy is to establish reserves through provisions for credit losses on the consolidated statements of comprehensive income for estimated losses on delinquent and other problem loans when it is determined that losses are expected to be incurred on such loans. Management’s determination of the appropriateness of the allowance is based on various factors requiring judgments and estimates, including management’s evaluation of the credit quality of the portfolio (determined through the assignment risk ratings and assessments of past due status), past loss experience, current economic conditions, the volume and type of lending conducted by the Company, composition of the portfolio, the amount of the Company’s classified assets, seasoning of the loan portfolio, the status of past due principal and interest payments, and other relevant factors. Two areas in which management exercises judgment are the assessment of risk ratings on the Company’s commercial loan portfolio and the application of qualitative adjustments to the quantitative measurements across all portfolios. A one risk rating, instantaneous shift upwards (improvement) and downwards (degradation) would decrease the allowance for credit losses by $19.0 million and increase the allowance for credit losses by $29.0 million, respectively. Similarly, a 10% change in the qualitative adjustments estimated by management would result in a $1.6 million change in the allowance for credit losses. Other changes in estimates may also have a significant impact on the consolidated financial statements. For further discussion of the allowance for credit losses, see the Asset Quality and Allowance for Credit Losses sections of this analysis and Note 1 and Note 7 of the footnotes to the consolidated financial statements.

Accounting for Acquired Loans, the Allowance for Acquired Credit Losses, and Related FDIC Loss Share Receivable

The Company accounts for its acquisitions under ASC Topic No. 805, Business Combinations, which requires the use of the purchase method of accounting. All identifiable assets acquired, including loans, are recorded at fair value. No allowance for credit losses related to the acquired loans is recorded on the acquisition date as the fair value of the loans acquired incorporates assumptions regarding credit risk. Loans acquired are recorded on the date of acquisition at fair value in accordance with the fair value methodology prescribed in ASC Topic No. 820, exclusive of the shared-loss agreements with the FDIC. These fair value estimates associated with acquired loans include estimates related to market interest rates and undiscounted projections of future cash flows that incorporate expectations of prepayments and the amount and timing of principal, interest and other cash flows, as well as any shortfalls thereof.

Over the life of the acquired loans, the Company continues to estimate the amount and timing of cash flows expected to be collected on individual loans or on pools of loans sharing common risk characteristics. These expected cash flow estimates are updated for new information on a quarterly basis. The Company performs a detailed credit review on a semi-annual basis. The Company evaluates quarterly whether the present value of estimated future cash flows of its loans determined using effective interest rates have decreased and if so, recognizes provisions for credit losses in its consolidated statement of comprehensive income. For any increases in cash flows expected to be collected, the Company adjusts the amount of accretable yield recognized on a prospective basis over the respective loan’s or pool’s remaining life.

Because the FDIC will reimburse the Company for certain loans acquired from CSB, Orion, Century, and Sterling should the Company experience a loss, an indemnification asset, the FDIC loss share receivable, is recorded at fair value at the acquisition date. The indemnification asset is recognized at the same time as the indemnified loans, and measured on the same basis, subject to collectability or contractual limitations. The shared loss agreements on the acquisition date reflect the reimbursements expected to be received from the FDIC, using an appropriate discount rate, which reflects counterparty credit risk and other uncertainties.

The shared loss agreements continue to be re-measured on the same basis as the related indemnified loans. Because the acquired loans are subject to the accounting prescribed by ASC Topic 310, subsequent changes in estimates underlying the basis of the shared loss agreements also follow that model. Deterioration in actual results from prior estimates of the credit quality of the loans is immediately recorded as an adjustment to the allowance for credit losses and would immediately increase the basis of the shared loss agreements, with the offset recorded through the consolidated statement of comprehensive income. Improvements in the credit quality or cash flows of loans (reflected as an adjustment to yield and accreted into income over the remaining life of the loans) decrease the basis of the shared loss agreements, with such decrease being amortized into income. Loss assumptions used in the basis of the indemnified loans

are consistent with the loss assumptions used to measure the indemnification asset. Fair value accounting incorporates into the fair value of the indemnification asset an element of the time value of money, which is accreted back into income over the life of the shared loss agreements.

Upon the determination of an incurred loss the indemnification asset will be reduced by the amount owed by the FDIC. A corresponding claim receivable is recorded until cash is received from the FDIC.

If expected loss severities for all acquired loans were to increase by 10% and 20%, the Company would recognize a gross expense to the provision for credit losses of $21.7 million and $43.3 million, respectively, which would be offset by an increase of $15.4 million and $31.4 million, respectively in the FDIC loss share receivable, respectively.

For further discussion of the Company’s acquisition and loan accounting, see Note 4 and Note 6 of the footnotes to the consolidated financial statements.

Valuation of Goodwill, Intangible Assets and Other Purchase Accounting Adjustments

The Company accounts for acquisitions in accordance with ASC Topic No. 805, which requires the use of the purchase method of accounting. For purchase acquisitions, the Company is required to record the assets acquired, including identified intangible assets, and liabilities assumed, at their fair value, which in many instances involves estimates based on third party valuations, such as appraisals, or internal valuations based on discounted cash flow analyses or other valuation techniques. The determination of the useful lives of intangible assets is subjective, as is the appropriate amortization period for such intangible assets. In addition, purchase acquisitions typically result in recording goodwill.

The Company performs a goodwill evaluation at least annually. As part of its testing, the Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the Company determines the fair value of a reporting unit is less than its carrying amount using these qualitative factors, the Company then compares the fair value of goodwill with its carrying amount, and then measures impairment loss by comparing the implied fair value of goodwill with the carrying amount of that goodwill. Based on management’s assessment of the qualitative factors in its goodwill impairment tests, the Company concluded that the fair value of the Company’s reporting unit was more likely than not above its carrying amount and accordingly did not recognize impairment in its tests of goodwill at October 1, 2012 or 2011. For additional information on goodwill and intangible assets, see Note 1 and Note 10 of the footnotes to the consolidated financial statements.

FINANCIAL CONDITION

EARNING ASSETS

Interest income associated with earning assets is the Company’s primary source of income. Earning assets are composed of interest or dividend-earning assets, including loans, securities, short-term investments and loans held for sale. Earning assets averaged $10.8 billion during 2012, a $1.1 billion, or 10.8%, increase when compared to 2011. The increase from the prior year was primarily the result of earning assets acquired during 2012. The following discussion highlights the Company’s major categories of earning assets.

The year-end mix of earning assets is shown in the following chart.

Loans and Leases

The Company’s total loan portfolio increased $1.1 billion, or 15.0%, to $8.5 billion at December 31, 2012, compared to $7.4 billion at December 31, 2011. The increase was driven by non-covered loan growth of $1.4 billion during the year, but was tempered by a decrease in loans covered by loss share agreements of $241.7 million, or 18.1%. Non-covered loan growth included loans acquired from Florida Gulf of $215.7 million and organic growth of $1.1 billion, or 18.8%. By loan type, the increase was primarily from commercial loan growth of $800.6 million and consumer loan growth of $371.6 million during 2012, 14.9% and 25.1% higher, respectively, than at the end of 2011.

The major categories of loans outstanding at December 31, 2012 and 2011 are presented in the following tables, segregated into covered loans and non-covered loans, including non-covered loans acquired from OMNI, Cameron, and Florida Gulf. The carrying amount of the covered loans and loans acquired from OMNI, Cameron, and Florida Gulf consisted of loans accounted for in accordance with ASC Topic 310-30 (i.e., loans impaired at the time of acquisition) and loans subject to ASC Topic 310-30 by analogy only (i.e., loans performing at the time of acquisition) as detailed in the following table.

Commercial Loans

Commercial real estate and commercial business loans generally have shorter repayment periods and more frequent repricing opportunities than consumer and mortgage loans. Total commercial loans increased $800.1 million, or 14.9%, during 2012, with $953.8 million in non-covered loan growth and a decrease in covered commercial loans of $153.7 million, or 17.4%. The Company continued to attract and retain commercial customers in 2012 as commercial loans were 73% of the total loan portfolio at December 31, 2012. Unfunded commitments on commercial loans were $1.8 billion at December 31, 2012, an increase of $404.5 million when compared to the prior year.

The Company’s investment in commercial real estate loans increased by $267.7 million during 2012, and was primarily the result of acquired commercial loans of $144.5 million. Growth, however, was tempered by a decrease in covered commercial real estate loans of $132.0 million. At December 31, 2012, commercial real estate loans totaled $3.6 billion, or 42.7% of the total loan portfolio, compared to 45.5% at December 31, 2011. The Company’s underwriting standards generally provide for loan terms of three to five years, with amortization schedules of generally no more than twenty years. Low loan-to-value ratios are maintained and usually limited to no more than 80% at the time of origination. In addition, the Company obtains personal guarantees of the principals as additional security for most commercial real estate loans.

As of December 31, 2012, the Company’s commercial business loans totaled $2.5 billion, or 29.9% of the Company’s total loan portfolio. This represents a $532.5 million, or 26.6%, increase from December 31, 2011, and is the result of loans acquired in 2012, but also the Company’s focused efforts to grow its small business loan portfolio. The Company originates commercial business loans on a secured and, to a lesser extent, unsecured basis. The Company’s commercial business loans may be term loans or revolving lines of credit. Term loans are generally structured with terms of no more than three to five years, with amortization schedules of generally no more than seven years. The Company’s commercial business term loans are generally secured by equipment, machinery or other corporate assets. The Company also provides for revolving lines of credit generally structured as advances upon perfected security interests in accounts receivable and inventory. Revolving lines of credit generally have an annual maturity. The Company obtains personal guarantees of the principals as additional security for most commercial business loans.

Non-covered commercial loans increased $809.4 million, or 18.0%, excluding the loans acquired from Florida Gulf. The Lafayette, Louisiana, Birmingham, Alabama, and Houston, Texas markets experienced the largest growth in their commercial loan portfolios, but that growth was partially offset by a decrease in balances in some of the Company’s other markets, the result primarily of payments on existing loans. On a market basis, growth in the non-covered portfolio was driven by the Company’s newer markets, including Mobile, Alabama, which grew its commercial loan portfolio $46.1 million, or 32.8%, since the end of 2011, and Houston, Texas, which increased its commercial loan portfolio 62.1%, or $328.8 million, in 2012. Birmingham, Alabama’s commercial loans grew $102.1 million, or

47.9%, while the Huntsville, Alabama market contributed loan growth of $50.4 million since December 31, 2011. In the Company’s more mature markets, New Orleans, Louisiana’s commercial loans grew $84.1 million, or 7.7%, during 2012. Offsetting these increases were decreases in the Northeast Arkansas and Southwest Louisiana markets, due primarily to loan payments.

Mortgage Loans

Residential 1-4 family loans comprise most of the Company’s mortgage loans. The vast majority of the Company’s residential 1-4 family mortgage loan portfolio is secured by properties located in its market areas and originated under terms and documentation which permit their sale in the secondary market. Larger mortgage loans of private banking clients and prospects are generally retained to enhance relationships, and also due to the expected shorter durations and relatively lower servicing costs associated with loans of this size. The Company does not originate or hold high loan to value, negative amortization, option ARM, or other exotic mortgage loans in its portfolio. Beginning in the third quarter of 2012, the Company began to invest in loans that would be considered subprime (e.g. loans with a FICO score of less than 620) in order to ensure compliance with relevant regulations. The Company expects to continue to invest in subprime loans through additional secondary market purchases, as well as direct originations, in 2013, albeit up to a limited amount. The total amount of subprime loans purchased or originated in the last six months of 2012 was $60.5 million, of which $44.9 million is either directly or indirectly guaranteed by a United States Government Agency.

The Company continues to sell the majority of conforming mortgage loan originations in the secondary market on a servicing-released basis and recognize the associated fee income rather than assume the interest rate risk associated with these longer term assets. The Company retains servicing on a limited portion of these loans upon sale. Total residential mortgage loans decreased $61.3 million, or 11.4%, compared to December 31, 2011. Of the total mortgage loan decrease since December 31, 2011, $68.2 million was a result of a decrease in covered mortgage loans and $21.3 million was a result of a decrease in non-acquired mortgage loans as existing loans were paid down and most of the new mortgage loan originations were sold. Acquired mortgage loans from Florida Gulf offset the decreases in the current year. The total decrease in mortgage loans was also offset partially by the $60.5 million in subprime loans the Company purchased from the secondary market during the third and fourth quarters of 2012.

Consumer and Credit Card Loans

The Company offers consumer loans in order to provide a full range of retail financial services to its customers. The Company originates substantially all of such loans in its primary market areas. At December 31, 2012, $1.9 billion, or 21.8%, of the Company’s total loan portfolio was comprised of consumer loans, compared to $1.5 billion, or 20.0%, at the end of 2011. The $371.7 million increase in total consumer loans compared to December 31, 2011 was primarily driven by home equity loan growth of $232.0 million and indirect automobile loan growth of $66.1 million.

Consistent with 2011, home equity loans comprised the largest component of the Company’s consumer loan portfolio at December 31, 2012. The balance of home equity loans increased 22.8% during 2012 to $1.3 billion at December 31, 2012. Non-covered home equity loans increased $250.5 million during 2012, a result of acquired loans from Florida Gulf, but also a result of the Company’s continued focus on expanding its total consumer portfolio through its additional investment in its consumer business, as well as increased activity from its existing clients. The Company’s sales and marketing efforts in 2012 have contributed to the growth in non-covered home equity loans since December 31, 2011. Unfunded commitments related to home equity loans and lines were $341.2 million at December 31, 2012, an increase of $105.0 million versus the prior year. The Company has approximately $384.7 million of loans with junior liens where the Company does not hold or service the respective loan holding senior lien. The Company believes it has addressed the risks associated with these loans in its allowance for credit losses, which is discussed below.

Indirect automobile loans comprised the second largest component of the Company’s consumer loan portfolio. Independent automobile dealerships originate these loans based upon the Company’s credit decisioning. The Company relies on the dealerships, in part, for loan qualifying information. To that extent, there is risk inherent in indirect automobile loans associated with fraud or negligence by the automobile dealership. To limit this risk, an emphasis is placed on established dealerships that have demonstrated reputable behavior, both within the communities we serve and through long-term relationships with the Company. The balance of indirect automobile loans increased 25.2% during the year, from $261.9 million at December 31, 2011 to $328.0 million at December 31, 2012, as the Company retained its focus on prime or low risk paper. The indirect portfolio increased to 3.9% of the total loan portfolio. The organic growth in the Company’s indirect automobile portfolio can be attributed to a couple of primary factors. During the latter part of 2011 and into 2012, the Company began to sign new dealers after limiting new business during the previous years due to a weakened economy. In addition, the Company has adjusted its interest rates on these loans to be more aligned with its competitors, which has provided the Company an opportunity to recapture some market share.

The Company’s credit card loans totaled $52.6 million at December 31, 2012, an 8.0% increase from December 31, 2011. The increase in credit card loans was a result of an increase in usage by customers during the year. Quarter-to-date average credit card balances have increased from $47.5 million in the fourth quarter of 2011 to $50.1 million in the fourth quarter of 2012.

The remainder of the consumer loan portfolio at December 31, 2012 was composed of direct automobile loans and other personal loans, and comprised 2.6% of the overall loan portfolio. At the end of 2012, the Company’s direct automobile loans totaled $60.2 million, a $21.6 million increase over December 31, 2011, and the Company’s other personal consumer loans were $160.1 million, a 42.9% increase from December 31, 2011, primarily a result of acquired Florida Gulf loans.

Loan Maturities

The following table sets forth the scheduled contractual maturities of the Company’s loan portfolio at December 31, 2011, unadjusted for scheduled principal reductions, prepayments or repricing opportunities. Demand loans, loans having no stated schedule of repayments and no stated maturity and overdraft loans are reported as due in one year or less. The average life of a loan may be substantially less than the contractual terms because of prepayments. As a result, scheduled contractual amortization of loans is not reflective of the expected term of the Company’s loan portfolio. Of the loans with maturities greater than one year, approximately 77.8% of the balance of these loans bears a fixed rate of interest.

Mortgage Loans Held for Sale

Loans held for sale increased $114.5 million, or 74.8%, to $267.5 million at December 31, 2012, compared to $153.0 million at December 31, 2011. The increase in the balance during 2012 was a result of an increase in origination activity during the year. The Company has originated $2.4 billion in mortgage loans during 2012.

Loans held for sale have primarily been fixed-rate single-family residential mortgage loans under contracts to be sold in the secondary market. In most cases, loans in this category are sold within thirty days of closing. Buyers generally have recourse to return a purchased loan to the Company under limited circumstances. Recourse conditions may include fraud in the origination, breach of representations or warranties, and documentation deficiencies. At December 31, 2012, the Company had $5.1 million in loans that have recourse conditions for which buyers have notified the Company of potential recourse action. The Company has recorded a reserve of $2.4 million for potential repurchases at December 31, 2012. During 2012, an insignificant number of loans were returned to the Company.

Asset Quality

The Company’s loan portfolio has gradually transitioned from that of a thrift to resemble portfolios held by commercial banks. This transition brings the potential for increased risks in the form of potentially higher levels of charge-offs and nonperforming assets, and increase rewards in the form of potentially increased levels of shareholder returns. Management has responded, as the risks present within the Company’s loan portfolio have evolved by tightening underwriting guidelines and procedures, implementing more conservative loan charge-off and nonaccrual guidelines, revising loan policies and developing an internal loan review function. As a result of management’s enhancements to underwriting loan risk/return dynamics, the credit quality of the Company’s loan portfolio has remained favorable when compared to peers. Management believes that it has demonstrated proficiency in managing credit risk through timely identification of significant problem loans, prompt corrective action, and transparent disclosure. Overall asset quality improved during 2012, primarily as a result of decreases in the number and amount of past due loans and nonperforming assets. Consistent with prior years, the assets and liabilities purchased and assumed through the Company’s four failed bank acquisitions continue to have a disproportionate impact on overall asset quality. The Company continues to closely monitor the risk-adjusted level of return within the loan portfolio.

Written underwriting standards established by the Board of Directors and management govern the lending activities of the Company. The commercial credit department, in conjunction with senior lending personnel, underwrites all commercial business and commercial real estate loans. The Company provides centralized underwriting of all residential mortgage, construction and consumer loans. Established loan origination procedures require appropriate documentation, including financial data and credit reports. For loans secured by real property, the Company generally requires property appraisals, title insurance or a title opinion, hazard insurance, and flood insurance, where appropriate.

Loan payment performance is monitored and late charges are assessed on past due accounts. A centralized department administers delinquent loans. Every effort is made to minimize any potential loss, including instituting legal proceedings as necessary. Commercial loans of the Company are periodically reviewed through a loan review process to provide an independent assessment of a loan’s risks. All other loans are also subject to loan review through a periodic sampling process. The Company exercises significant judgment in determining the risk classification of its commercial loans.

The Company utilizes an asset risk classification system in accordance with guidelines established by the Federal Reserve Board as part of its efforts to monitor commercial asset quality. In connection with examinations of insured institutions, both federal and state examiners also have the authority to identify problem assets and, if appropriate, classify them. There are three classifications for problem assets: “substandard,” “doubtful” and “loss”, all of which are considered adverse classifications. Substandard assets have one or more defined weaknesses and are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Doubtful assets have the weaknesses of substandard assets with the additional characteristic that the weaknesses make collection or liquidation in full questionable, and there is a high probability of loss based on currently existing facts, conditions and values. An asset classified as loss is considered not collectable and of such little value that continuance as an asset of the Company is not warranted. Commercial loans with adverse classifications are reviewed by the Board Risk Committee of the Board of Directors at least monthly. Loans are placed on nonaccrual status when they are 90 days or more past due unless, in the judgment of management, the probability of timely collection of interest is deemed to be sufficient to warrant further accrual. When a loan is placed on nonaccrual status, the accrual of interest income ceases and accrued but unpaid interest attributable to the current year is reversed against interest income. Accrued interest receivable attributable to the prior year is recorded as a charge-off to the allowance for credit losses.

Real estate acquired by the Company through foreclosure or by deed-in-lieu of foreclosure is classified as other real estate owned (“OREO”), and is recorded at the lesser of the related loan balance (the pro-rata carrying value for acquired loans) or estimated fair value less estimated costs to sell.

Under generally accepted accounting principles, certain loan modifications or restructurings are designated as troubled debt restructurings (“TDRs”). In general, the modification or restructuring of a debt constitutes a TDR if the Company, for economic or legal reasons related to the borrower’s financial difficulties, grants a concession to the borrower that the Company would not otherwise consider under current market conditions.

Nonperforming Assets

The Company defines nonperforming assets as nonaccrual loans, accruing loans more than 90 days past due, OREO and foreclosed property. Management continually monitors loans and transfers loans to nonaccrual status when warranted.

Loans acquired through failed bank acquisitions, referred to as covered loans, are covered by loss sharing agreements with the FDIC, whereby the FDIC reimburses the Company for the majority of the losses incurred during the loss share claim period. Acquisition date fair values of loans covered by loss sharing agreements were determined without regard to the loss sharing agreements. In addition to covered loans, the Company also accounts for other loans acquired with deteriorated credit quality, as well as all loans acquired with significant discounts that did not exhibit deteriorated credit quality at acquisition, in accordance with ASC 310-30. Collectively, all loans accounted for under ASC 310-30 are referred to as purchased impaired loans. Application of ASC 310-30 results in significant accounting differences, compared to loans originated or acquired by the Company that are not accounted for under ASC 310-30. At acquisition, purchased impaired loans were individually evaluated and assigned to loan pools based on common risk characteristics, which included loan performance at the time of acquisition, loan type based on regulatory reporting guidelines, and/or the nature of collateral. The acquisition date fair values of each pool were estimated based on the expected cash flows of the underlying loans. Certain loan level information, including outstanding principal balance, maturity, term to re-price (if a variable rate loan), and interest rate were used to estimate the expected cash flows for each loan pool. ASC 310-30 does not permit carry over or recognition of an allowance for credit losses at acquisition. Credit quality deterioration, also referred to as credit losses, evident at acquisition with individual loans was reflected in the acquisition date fair value through the reduction of cash flows expected to be received over the life of loans. A provision for credit losses is recognized and an allowance for credit losses is recorded subsequent to acquisition to the event that re-estimated expected losses exceed losses estimated at acquisition. Purchased impaired loans were considered to be performing as of the acquisition date regardless of their past due status based on their contractual terms. In accordance with regulatory reporting guidelines, purchased impaired loans that are contractually past due are reported as past due and accruing based on the number of days past due.

Due to the significant difference in the accounting for covered loans and the related FDIC loss sharing agreements, as well as non-covered acquired loans accounted for as purchased impaired loans, and given the significant amount of acquired impaired loans that are past due but still accruing, the Company believes inclusion of these loans in certain asset quality ratios that reflect nonperforming assets in the numerator or denominator (or both) results in significant distortion to these ratios. In addition, because loan level charge-offs related to purchased impaired loans are not recognized in the financial statements until the cumulative amounts exceed the original loss projections on a pool basis, the net charge-off ratio for acquired loans is not consistent with the net charge-off ratio for other loan portfolios. The inclusion of these loans in certain asset quality ratios could result in a lack of comparability across quarters or years, and could impact comparability with other portfolios that were not impacted by purchased impaired loan accounting. The Company believes that the presentation of certain asset quality measures excluding either covered loans or all purchased impaired loans, as indicated below, and related amounts from both the numerator and denominator provides better perspective into underlying trends related to the quality of its loan portfolio. Accordingly, the asset quality measures in the tables below present asset quality information excluding either covered loans or all purchased impaired loans, as indicated within each table, and related amounts.

Nonperforming assets excluding purchased impaired loans decreased $2.0 million, or 2.6%, as compared to December 31, 2011. The decrease resulted from a $7.0 million decrease in nonperforming loans, primarily attributable to a decrease in nonaccrual loans, which

was partially offset by a $5.0 million increase in OREO. The Company’s ongoing business strategy of maximizing shareholder return includes periodic review of the branch network. This periodic review resulted in the closure of ten branches during 2012, resulting in $4.2 million of the total $5.0 million increase in OREO. The remaining $0.8 million increase represents real estate acquired through foreclosure.

The following table sets forth the composition of the Company’s non-covered nonperforming assets, including accruing loans past due 90 or more days and TDRs, as of December 31, 2012 and December 31, 2011.

Nonperforming loans were 0.73% of total legacy loans at December 31, 2012, 32 basis points lower than at December 31, 2011. If covered loans and acquired loans accounted for in pools that meet nonperforming criteria are included, nonperforming loans were 6.42% of total loans at December 31, 2012 and 10.13% at December 31, 2011. The allowance for credit losses as a percentage of nonperforming loans was 150.6% at December 31, 2012 and 133.0% at December 31, 2011. Including covered loans and pooled loans, the allowance coverage of total loans was 2.96% at December 31, 2012 and 2.62% at December 31, 2011.

Nonperforming asset balances as a percentage of total assets have remained at relatively low levels. Total nonperforming assets were 0.69% of non-covered assets at December 31, 2012, 17 basis points below December 31, 2011. Consistent with the improvement in asset quality, the Company’s reserve for credit losses as a percentage of loans excluding reserves for acquired loans decreased 30 basis points to 1.10% at December 31, 2012.

Loans defined as TDRs not included in nonperforming assets increased to $2.4 million at the end of 2012. Total TDRs not covered by loss share agreements totaled $17.7 million at December 31, 2012, $6.2 million, or 26.1%, lower than December 31, 2011. 20 credits totaling $4.6 million were added as TDRs in 2012, but these additions were offset by loan payments and charge-offs in 2012.

The Company had gross charge-offs on non-covered loans of $9.9 million during the twelve months ended December 31, 2012. Offsetting these charge-offs were recoveries of $5.3 million. As a result, net charge-offs on non-covered loans during the year were $4.6 million, or 0.07% of average loans, as compared to net charge-offs of $7.6 million, or 0.13%, in 2011.

At December 31, 2012, excluding loans covered by the FDIC loss share agreements, the Company had $228.7 million of assets classified as substandard, $2.9 million of assets classified as doubtful, and no assets classified as loss (before the application of loan discounts to acquired loans). At such date, the aggregate of the Company’s classified assets was 1.98% of total assets, 2.72% of total loans, and 3.13% of non-covered loans. At December 31, 2011, the aggregate of the Company’s classified assets, $199.9 million, was 1.75% of total assets, 2.79% of total loans, and 3.40% of non-covered loans. The increase in total classified assets was a result of Florida Gulf loans acquired during the current year. A reserve for credit losses has been recorded for all substandard loans at December 31, 2012 according to the Company’s allowance policy. Excluding purchased impaired loans, the Company’s classified assets totaled $176.0 million, compared to $157.0 million at December 31, 2011. The $19.0 million increase was a result primarily of eight credits added during the current year for $29.5 million and was not an indicator of overall asset quality deterioration.

In addition to the problem loans described above, excluding covered loans, there were $122.1 million of loans classified special mention at December 31, 2012, which in management’s opinion were subject to potential future rating downgrades. Special mention loans are defined as loans where known information about possible credit problems of the borrowers cause management to have some doubt as to the ability of these borrowers to comply with the present loan repayment terms and which may result in future disclosure of these loans

as nonperforming. Special mention loans decreased $84.3 million, or 40.8%, from December 31, 2011, many of which moved to substandard status noted above.

Past Due Loans

Past due status is based on the contractual terms of loans. The majority of the Company’s non-covered portfolio exhibited an improvement in past due status from the end of the previous year.

At December 31, 2012, total past due loans excluding covered loans were 1.71% of total loans, a decrease of 26 basis points from December 31, 2011. Including covered loans, loans past due 30 days or more were 6.76% of total loans before discount adjustments at December 31, 2012 and 10.57% at December 31, 2011. Past due non-covered loans (including nonaccrual loans) increased $7.1 million, or 5.9%, from December 31, 2011, and can be attributed to the $13.3 million in past due loans acquired from Florida Gulf during 2012. Additional information on the Company’s non-covered past due loans is presented in the following table.

⁽¹⁾ For acquired loans, balance represents the outstanding balance of loans that would otherwise meet the Company’s definition of nonaccrual loans.

The $7.1 million increase in non-covered past due loans was the result of an $8.5 million increase in nonaccrual loans, offset by a $1.4 million decrease in accruing loans past due from 2011. Loans past due at December 31, 2012 that were acquired from Florida Gulf totaled $13.3 million. Excluding these acquired loans, non-covered loans past due were $114.6 million, a decrease of $6.2 million, or 5.1% from December 31, 2011.

Commercial nonaccrual loans increased $3.3 million, or 4.3%, and mortgage nonaccrual loans increased $4.2 million, while consumer nonaccrual loans increased $1.0 million since December 31, 2011. The increase in consumer nonaccrual loans was a result of the placement of past due consumer loans on nonaccrual status during 2012 in response to their continued past due status. The movement of these loans to nonaccrual status in the current year helped to drive the decrease in accruing consumer loans past due (excluding past due loans acquired from OMNI, Cameron, and Florida Gulf) from December 31, 2011, from $6.4 million to $6.0 million, a 5.1% decrease.

In the Company’s non-covered commercial loan portfolio, total accruing loans past due increased $0.1 million, or 0.3%, from December 31, 2011. The total increase was a result of a limited number of past due loans in the Company’s legacy portfolio, as past due commercial loans acquired in 2011 and 2012 decreased $3.0 million, or 22.8%. The $3.1 million increase in legacy commercial loans was driven by a $3.3 million increase in commercial loans past due less than 60 days, which the Company does not consider a significant indicator of a decline in overall commercial loan credit quality. Total commercial loans past due less than 60 days were 0.10% of non-acquired commercial loans at December 31, 2012.

Total non-covered mortgage loans past due increased $0.1 million, or 3.8%, during 2012. Although asset quality has declined in the mortgage portfolio, 69.4% of the past due loans were past due less than 90 days, including 25.3% past due less than 60 days. At December 31, 2011, those percentages were 49.1% and 33.9%, respectively. Management is continually monitoring the past due status of these mortgage loans for indicators of overall asset quality issues. Past due loans in the acquired mortgage loan portfolio decreased $0.4 million from December 31, 2011.

Covered Loans

The loans and foreclosed real estate that were acquired in the CSB, Orion, Century, and Sterling acquisitions in 2009 and 2010 are covered by loss share agreements between the FDIC and IBERIABANK, which afford IBERIABANK significant loss protection. As a result of the loss protection provided by the FDIC, the risk of loss on the acquired loans and foreclosed real estate is significantly different from those assets not covered under the loss share agreements.

As described above, covered assets were recorded at their acquisition date fair values.

Although covered loans are not included in the Company’s nonperforming assets, in accordance with bank regulatory reporting standards, both acquired loans considered impaired at the time of acquisition and those performing at the time of acquisition that meet the Company’s definition of a nonperforming loan at each balance sheet date are discussed below. Included in the discussion are all covered loans that are contractually past due based on the number of days past due. Certain measures of the asset quality of covered loans are discussed below. Loan balances are reported before consideration of applied loan discounts, as these discounts were recorded based on the estimated cash flow of the total loan pool and not on a specific loan basis. The loss share agreements with the FDIC limit the Company’s exposure to loss during the loss claim period to no more than 20% of incurred losses for all covered loans and as little as 5% of incurred losses for certain loans. Therefore, balances discussed below are for general comparative purposes only and do not represent the Company’s risk of loss on covered assets.

⁽¹⁾ For covered loans, balance represents the outstanding balance of loans that would otherwise meet the Company’s definition of nonaccrual loans.

Total covered loans past due at December 31, 2012 totaled $465.3 million before discounts, a decrease of $248.7 million, or 34.8%, from December 31, 2011. Past due loans at the end of 2012 included $440.6 million in loans that would otherwise meet the Company’s definition of nonaccrual loans and $24.7 million in accruing loans past due greater than 30 days. Of the $24.7 million in accruing loans past due, $22.1 million, or 89.4%, were past due less than 90 days. The indemnification agreements on covered assets include a provision for recapture of a portion of interest if the interest is included in total losses on the covered asset.

Of the $248.7 million decrease in covered loans past due, loans past due 30 to 89 days decreased $39.2 million, or 63.9%, while nonperforming loans (defined as accruing loans greater than 90 days past due and loans that meet the definition of nonaccrual loans) decreased $209.5 million, or 32.1%. These decreases were a result primarily of payments on the loan balances during the current year.

Allowance for Credit Losses

The allowance for credit losses represents management’s best estimate of probable credit losses inherent at the balance sheet date. Determination of the allowance for credit losses involves a high degree of complexity and requires significant judgment. Several factors are taken into consideration in the determination of the overall allowance for credit losses, including a qualitative component. These factors include, but are not limited to, the overall risk profiles of the loan portfolios, net charge-off experience, the extent of impaired loans, the level of nonaccrual loans, the level of 90 days past due loans and the overall percentage level of the allowance. The Company also considers overall asset quality trends, changes in lending and risk management practices and procedures, trends in the nature and volume of the loan portfolio, including the existence and effect of any portfolio concentrations, changes in experience and depth of lending staff, legal, regulatory and competitive environment, national and regional economic trends, and data availability and

applicability that might impact the portfolio. See the “Application of Critical Account Policies and Estimates” section for more information.

During 2012, the Company did not substantively change any material aspect of its overall approach in the determination of the allowance for credit losses and there have been no material changes in assumptions or estimation techniques as compared to prior periods that impacted the determination of the current period allowance.

Certain inherent, but unconfirmed losses are probable within the loan portfolio. The Company’s current methodology for determining the level of losses is based on historical loss rates, current credit grades, specific allocation and other qualitative adjustments. In a stable or deteriorating credit environment, heavy reliance on historical loss rates and the credit grade rating process, results in model-derived required reserves that tend to slightly lag behind portfolio deterioration. Similar lags can occur in an improving credit environment whereby required reserves can lag slightly behind portfolio improvement. Given these model limitations, qualitative adjustment factors may be incremental or decremental to the quantitative model results.

The manner in which the allowance for credit losses is determined is based on the accounting method applied to the underlying loans. The Company delineates between loans accounted for under the contractual yield method, primarily legacy loans, and loans accounted for as purchased impaired loans, primarily acquired loans.

Legacy Loans

Legacy loans represent loans accounted for under the contractual yield method. The Company’s legacy loans include loans originated by the Company and acquired loans that are not accounted for as acquired credit impaired loans. See the “Application of Critical Account Policies and Estimates” for more information.

Acquired Loans

Acquired loans, which include covered loans and certain non-covered loans, represent loans acquired by the Company that are accounted for in accordance with ASC 310-30. See discussion above, as well as the “Application of Critical Account Policies and Estimates” section for more information.

Loans acquired in business combinations were recorded at their acquisition date fair values, which were based on expected cash flows and included estimates of expected future credit losses. Under current accounting principles, information regarding the Company’s estimates of loan fair values may be adjusted for a period of up to one year as the Company continues to refine its estimate of expected future cash flows in the acquired portfolio. Within a one-year period, if the Company discovers that it has materially underestimated the credit losses expected in the loan portfolio based on information available at the acquisition date, it will retroactively reduce or eliminate the gain and/or increase goodwill recorded on the acquisition. If the Company determines that losses arose after the acquisition date, the additional losses will be reflected as a provision for credit losses.

At December 31, 2012, the Company had an allowance for credit losses of $168.6 million to reserve for probable losses currently in the covered loan portfolio arising after the losses estimated at the respective acquisition dates. In addition, during the year ended December 31, 2012, the Company recorded an allowance for credit losses of $8.8 million to reserve for expected losses currently in the non-covered acquired loan portfolios that have arisen after the losses estimated at the respective acquisition dates.

Based on facts and circumstances available, management of the Company believes that the allowance for credit losses was appropriate at December 31, 2012 to cover probable losses in the Company’s loan portfolio. However, future adjustments to the allowance may be necessary, and the Company’s results of operations could be adversely affected, if circumstances differ substantially from the assumptions used by management in determining the allowance for credit losses.

The following tables set forth the activity in the Company’s allowance for credit losses for the periods indicated.

The allowance for credit losses was $251.6 million at December 31, 2012, or 2.96% of total loans, $57.8 million higher than at December 31, 2011. The allowance as a percentage of loans was 34 basis points above the 2.62% at December 31, 2011.

The increase in the allowance was primarily related to increased reserves on the covered and acquired loan portfolios, but was also a result of reserves on loan growth for non-acquired loans at December 31, 2012. The allowance for credit losses on the non-covered portion of the Company’s loan portfolio increased primarily due to loan growth during 2012, as asset quality improved over the prior year as evidenced by continued lower levels of net charge-offs and past due loans. The non-covered allowance for credit losses also includes a reserve of $8.8 million on the Company’s non-covered acquired loans to reserve for losses probable in those portfolios at December 31, 2012 above estimated expected credit losses at acquisition.

The allowance for credit losses on covered loans increased $49.7 million, or 41.8%, from December 31, 2011 and was primarily the result of a change in expected cash flows on certain of the Company’s acquired loan pools during 2012. The reserve was adjusted during the year to cover the additional expected losses in these pools. The increase in the allowance on covered loans was tempered partially by the closure of a limited number of commercial and mortgage loan pools. With the closure of the loan pools, the remaining recorded investment in the loan pools was charged off against the allowance recorded for the loan pools and certain previously established reserves were reversed. On a gross basis, the Company recorded an additional $91.2 million in the current year to reserve for these estimated cash flow changes. The allowance on covered loans was reduced, however, by $26.3 million when loan collateral was moved to OREO during 2012 and by $15.1 million for net charge-off activity.

At December 31, 2012, excluding the acquired loan portfolios, the allowance for credit losses covers nonperforming loans 1.5 times. On that same basis, the allowance for credit losses on non-covered loans covers total past due loans 1.2 times at December 31, 2012. Including acquired loans, the allowance for credit losses covers 64.9% of total past due and nonaccrual loans, an increase compared to the December 31, 2011 coverage of 62.0%.

FDIC Loss Share Receivable

As part of the FDIC-assisted acquisitions in 2009 and 2010, the Company recorded a $1.0 billion receivable from the FDIC, which represents the fair value of the expected reimbursable losses covered by the loss share agreements. The FDIC loss share receivable decreased $168.8 million, or 28.5%, during 2012 as the Company claimed reimbursements from the FDIC resulting from loan charge-offs, OREO sales, and OREO write-downs, included in other assets discussed below. The loss share receivable also decreased as a result of amortization during the year. Offsetting the decreases was an $84.1 million increase to account for either a decrease in expected cash flows from original loss estimates or additional losses on revised estimates on some of the Company’s covered loan pools.

The following table sets forth the activity in the FDIC loss share receivable asset for the periods indicated.

The Company does not anticipate owing any consideration previously received under indemnification agreements to the FDIC under the “clawback” provisions of these agreements. Of the three agreements with the FDIC that contain clawback provisions, cumulative losses to date under two of these agreements have exceeded the calculated loss amounts which would result in clawback if not incurred. The sum of the historical and remaining projected losses under the remaining agreement is in excess of the clawback amount stated in that agreement.

Refer to the “Other Assets” discussion below for additional amounts due from the FDIC related to loss share agreements.

Investment Securities

Investment securities decreased by $47.9 million to $2.0 billion at December 31, 2012. The decrease was due to sales of available for sale investments and maturities and calls of both available for sale and held to maturity investments during the year. These sales and maturities were offset partially by purchases of investment securities during 2012 and acquired securities of $56.8 million from Florida Gulf. As a percentage of total assets, investment securities decreased to 14.9% of total assets at December 31, 2012, from 17.0% at December 31, 2011. Investment securities were 18.1% of average earnings assets in the current year and 20.8% in 2011.

The following table shows the carrying values of securities by category as of December 31^st for the years indicated.

Funds generated as a result of sales and prepayments are used to fund loan growth and purchase other securities. The Company continues to monitor market conditions and take advantage of market opportunities with appropriate risk and return elements.

The Company assesses the nature of the losses in its investment portfolio periodically to determine if there are losses that are deemed other-than-temporary. In its analysis of these securities, management considers numerous factors to determine whether there are instances where the amortized cost basis of the debt securities would not be fully recoverable, including, but not limited to:

• the length of time and extent to which the fair value of the securities was less than their amortized cost,

• whether adverse conditions were present in the operations, geographic area, or industry of the issuer,

• the payment structure of the security, including scheduled interest and principal payments, including the issuer’s failures to make scheduled payments, if any, and the likelihood of failure to make scheduled payments in the future,

• changes to the rating of the security by a rating agency, and

• subsequent recoveries or additional declines in fair value after the balance sheet date.

Management believes it has considered these factors, as well as all relevant information available, when determining the expected future cash flows of the securities in question. Based on its analysis at December 31, 2011, the Company recorded an other-than-temporary impairment charge of $0.5 million during the fourth quarter of 2011 on one unrated municipal revenue bond. During the year, management assessed the operating environment of the bond issuer as adverse and thus concluded the other-than-temporary impairment charge was warranted. The specific impairment was related to the loss of the contracted revenue source required for bond repayment. The additional charge in 2011 brought the total impairment to 50% of the par value of the bond and provided a fair value of the bonds that was consistent with current market pricing. Because adverse conditions were noted in the operations of the bond issuer, the Company recorded the other-than-temporary impairment, but noted no further deterioration in the operating environment of the bond issuer. No other declines in the market value of the Company’s investment securities are deemed to be other-than-temporary at December 31, 2012 and December 31, 2011.

Note 5 of the footnotes to the consolidated financial statements provides further information on the Company’s investment securities.

Short-term Investments

Short-term investments result from excess funds that fluctuate daily depending on the funding needs of the Company and are currently invested overnight in interest-bearing deposit accounts at the FHLB of Dallas and Atlanta, the total balance of which earns interest at the current FHLB discount rate. The balance in interest-bearing deposits at other institutions increased $343.7 million, or 90.6%, from $379.1 million at December 31, 2011 to $722.8 million at December 31, 2012. The primary cause of the increase was deposit growth during 2012 providing available funds to the Company to fund loan growth and pay down its long-term debt, all in an attempt to improve its net interest margin. The Company’s cash activity is further discussed in the “Liquidity” section below.

⁽¹⁾ Other interest-bearing assets are composed primarily of trust preferred common securities.

The $13.9 million decrease in FHLB and FRB stock was the result of $35.4 million in stock repurchases in 2012. The repurchases are mandatory for eligible stock based on FHLB regulations. The repurchases were partially offset by $19.8 million in purchases of stock and $1.6 million of acquired stock from Florida Gulf during 2012.

Fed funds sold and financing transactions represent short-term excess liquidity, and the balance varies based on the daily requirements of short-term liquidity needed by the Company and its subsidiaries for loan growth and other operating activities. The Company had $4.9 million in financing transactions outstanding at the end of 2012, whereas there were no fed funds sold or financing transactions at December 31, 2011. There was no change to the balance of other interest-bearing assets from 2011.

The $17.9 million increase in premises and equipment in 2012 was a result of acquired assets of $13.6 million from Florida Gulf, as well as additional capitalized expenditures at the Company’s branches during the current year. The investment in additional branch property is part of the Company’s growth strategy and expansion into new markets. Total additions from the acquisition and new branch assets were offset by movement of branches closed during 2012 to OREO and the current year depreciation taken on the assets in service.

The $3.7 million increase in the Company’s bank-owned life insurance balance was a result of the income earned on policies during 2012.

The $32.1 million increase in goodwill was a result of $32.4 million in goodwill resulting from the Florida Gulf acquisition during the third quarter of 2012, but was offset partially by adjustments recorded to the acquired goodwill from the OMNI and Cameron acquisitions during the second quarter of 2011. The goodwill adjustment was recorded to offset the fair value adjustments recorded on the acquired deferred tax asset and property balances. See Note 10 to these consolidated financial statements for additional information on the changes in goodwill.

The $4.9 million decrease in core deposit intangibles was due to amortization expense during the current year. There was no core deposit intangible asset created in the Florida Gulf acquisition in the current year due to the current and projected low interest rate environment.

The $3.8 million decrease in accrued interest receivable from December 31, 2011 was attributable to both the timing of interest payments during the year and the decrease in the yields on variable-rate earning assets. Partially offsetting these decreases was an increase in accrued interest from the growth of the Company’s interest-earning assets during 2012.

Other real estate includes all real estate, other than bank premises used in bank operations, that is owned or controlled by the Company, including real estate acquired in settlement of loans and former bank premises no longer used. The $3.5 million decrease in the Company’s OREO balance from December 31, 2011 was a result of the sale of numerous OREO properties during 2012, but was offset partially by the movement of $4.2 million in former bank properties to OREO. Covered OREO properties were $77.2 million and $84.6 million at December 31, 2012 and 2011, respectively, which represented a decrease of $7.3 million, or 8.8%, during the current year. Non-covered OREO increased $3.8 million, or 9.4%, and was primarily a result of the former bank properties noted above.

The $9.1 million increase in the market value of the Company’s derivatives was primarily attributable to additional derivatives from the Company’s interest rate lock commitments and forward sales contracts during the current year. The total change in market value was also a result of additional customer derivative and equity-indexed CD derivative product agreements.

The balance due to the Company from the FDIC from claims associated with the loss share agreements decreased $8.1 million during the current year. The decrease in the balance was a result of the timing of repayment from the FDIC of losses submitted and timing of losses incurred. The Company’s submission of losses has remained steady compared to 2011 as the Company continues to manage the covered assets to ultimate disposition in a manner that is least loss to the FDIC. The balance due from the FDIC includes the reimbursable portion of incurred losses, net of recoveries (as those terms are defined in the respective loss share agreements) and reimbursable expenses, which were approximately $3.3 million and $5.8 million at December 31, 2012 and 2011, respectively.

The $17.5 million increase in the Company’s investments in new market tax credits is a result of additional investments in tax credit entities of $21.4 million during the third and fourth quarters of 2012, but was offset partially by the amortization of the tax credits as they are recognized in the Company’s income tax provision calculation.

The $27.1 million decrease in other assets since December 31, 2011 was primarily the result of a decrease of $29.2 million in the Company’s current income tax receivable as a result of the income earned during the year. Increases in the Company’s other assets since December 31, 2011 were driven by the assets acquired from Florida Gulf, as the Company’s prepaid assets decreased $9.3 million, with the largest decrease coming in the Company’s prepaid FDIC insurance assessment of $7.9 million as the Company incurred additional insurance expense during the year.

There was no significant change in the Company’s title plant balance since December 31, 2011.

FUNDING SOURCES

Deposits obtained from clients in its primary market areas are the Company’s principal source of funds for use in lending and other business purposes. The Company attracts local deposit accounts by offering a wide variety of accounts, competitive interest rates and convenient branch office locations and service hours. Increasing core deposits through acquisitions and the development of client relationships is a continuing focus of the Company. Borrowings have become an important funding source as the Company has grown. Other funding sources include short-term and long-term borrowings, subordinated debt and shareholders’ equity. Refer to the “Liquidity” section below for further discussion of the Company’s sources and uses of funding sources. The following discussion highlights the major changes in the mix of deposits and other funding sources during 2012.

Deposits

The Company’s ability to attract and retain customer deposits is critical to the Company’s continued success. During 2012, total deposits increased $1.5 billion, or 15.7%, totaling $10.7 billion at December 31, 2012, as total noninterest-bearing deposits increased $482.6 million and interest-bearing deposits increased $976.7 million, or 12.5%, from December 31, 2011. Acquired Florida Gulf deposits of $286.0 million accounted for 19.6% of the total growth since the end of 2011. Increases in the Company’s core deposit products were offset by a continued decline in total time deposits, as higher-priced certificates of deposit (“CDs”) matured and were not renewed due to continued rate reductions.

The following table and chart sets forth the composition of the Company’s deposits as of December 31^st of the years indicated.

TABLE 18—DEPOSIT COMPOSITION BY PRODUCT

(Dollars in thousands)	2012				2011				2010				2009				2008
Noninterest-bearing deposits	$	1,967,662	18	%	$	1,485,058	16	%	$	878,768	11	%	$	874,885	11	%	$	620,637	16	%

From a product perspective, interest-bearing deposits increased $976.7 million, or 12.5%, driven by acquired Florida Gulf deposits of $228.5 million. Excluding these acquired deposits, interest-bearing deposits increased $748.2 million, or 9.6%. Growth of $1.4 billion, or 26.0%, in transaction and limited transaction accounts more than offset the deposit losses from time deposits of $391.5 million. The decrease was seen in many of the Company’s markets, including the New Orleans, Lafayette, and Southwest Louisiana markets, as well as Southeast Florida, where higher-priced certificates of deposit matured and were either not renewed or renewed at lower interest rates. The 32.5% increase in noninterest-bearing deposits provided the Company with a good source of available funds for continued asset growth. Noninterest-bearing deposits increased $482.6 million from December 31, 2011. $57.6 million, or only 11.9%, of the year-to-date growth was a result of acquired deposits from Florida Gulf.

Total time deposits decreased $391.5 million, or 15.4%, during the current year. Certificates of deposit in denominations of $100,000 and over decreased $231.1 million, or 16.8%, from $1.4 billion at December 31, 2011 to $1.1 billion at December 31, 2012. The following table details large-denomination certificates of deposit by remaining maturities at December 31^st of the years indicated.

Additional information regarding deposits is provided in Note 12 of the footnotes to the consolidated financial statements.

From a market perspective, total deposit growth was seen primarily in the Company’s newer Houston, Texas and Mobile, Alabama markets, as well as the New Orleans, Lafayette, and Baton Rouge, Louisiana markets. Houston experienced growth of $277.8 million, 106.6% above December 31, 2011 deposit levels. Mobile’s total deposits increased $45.7 million, or 36.0%. The New Orleans market increased total deposits 12.5%, or $182.3 million, during the current year. The Lafayette and Baton Rouge, Louisiana markets contributed total deposit growth of $164.9 million and $108.8 million, respectively, during 2012. Total deposit growth was offset by deposit runoff in two of the five primary Florida markets, Sarasota ($29.6 million, or 4.5%) and Southeast Florida ($11.7 million, or 2.2%). Deposit runoff was also noted in the Northeast and Southwest Louisiana markets, as total deposits decreased 5.2% and 12.6%, respectively, also a result of time deposit runoff.

Short-term Borrowings

The Company may obtain advances from the FHLB of Dallas based upon the common stock it owns in the FHLB of Dallas and certain of its real estate loans and investment securities, provided certain standards related to the Company’s creditworthiness have been met. These advances are made pursuant to several credit programs, each of which has its own interest rate and range of maturities. The level of short-term borrowings can fluctuate significantly on a daily basis depending on funding needs and the source of funds chosen to satisfy those needs.

The Company also enters into repurchase agreements to facilitate customer transactions that are accounted for as secured borrowings. These transactions typically involve the receipt of deposits from customers that the Company collateralizes with its investment portfolio and have rates ranging from 0.09% to 0.80%. The following table details the average and ending balances of repurchase transactions as of and for the years ending December 31:

TABLE 20—REPURCHASE TRANSACTIONS

(In thousands)	2012		2011		2010
Average balance	$	243,248	$	213,588	$	198,355
Ending balance		303,045		203,543		220,328

Since December 31, 2011, total short-term borrowings decreased $92.5 million, or 23.4%, to $303.0 million at December 31, 2012. The decrease was a result of the payoff of $192.0 million in short-term FHLB advances during the year, but was partially offset by an increase of $99.5 million in the Company’s securities sold under agreements to repurchase ($9.8 million of which was acquired from Florida Gulf). On an average basis, short-term borrowings increased 29.1% from 2011. The increase in the average outstanding balance was largely due to management’s decision to take advantage of lower-cost funding sources during the current year. Short-term FHLB advances averaged $40.8 million in 2012, an increase of $34.5 million from 2011.

Total short-term debt was 2.6% of total liabilities and 41.7% of total borrowings at December 31, 2012 compared to 3.8% and 46.6%, respectively, at December 31, 2011. On an average basis, short-term borrowings were 2.7% of total liabilities and 39.7% of total borrowings in the current year, compared to 2.3% and 33.3%, respectively, during 2011.

The weighted average rate paid on short-term borrowings was 0.22% for 2012, compared to 0.26% for 2011. For additional information regarding short-term borrowings, see Note 13 of the consolidated financial statements.

Long-term Debt

The Company’s long-term borrowings decreased $29.4 million, or 6.5%, to $423.4 million at December 31, 2012, compared to $452.7 million at December 31, 2011. The decrease in borrowings from December 31, 2011 is a result of the scheduled repayment of a portion of the Company’s long-term advances from the FHLB during 2012.

On average, the Company’s long-term debt decreased to $431.1 million for 2012. Average long-term debt was 4.1% of total liabilities during 2012, lower than the year-to-date average during 2011 of 4.6%. On a period-end basis, long-term debt was 3.6% of total liabilities at December 31, 2012, also a decrease from 4.4% at December 31, 2011.

The Company’s long-term borrowings at December 31, 2012 included $233.8 million in fixed-rate advances from the FHLB of Dallas and Atlanta which cannot be paid off without incurring substantial prepayment penalties. The Company’s remaining debt consists of $111.9 million of junior subordinated deferrable interest debentures of the Company and $77.7 million in notes payable on investments in the Company’s new market tax credit entities. The debentures are issued to statutory trusts that were funded by the issuance of floating rate capital securities of the trusts and qualify as Tier 1 Capital for regulatory purposes. Interest is payable quarterly and may be deferred at any time at the election of the Company for up to 20 consecutive quarterly periods. During any deferral period, the Company is subject to certain restrictions, including being prohibited from declaring dividends to its common shareholders. The securities are redeemable by the Company in whole or in part after five years, or earlier under certain circumstances.

The following table summarizes each outstanding issue of junior subordinated debt. For additional information, see Note 14 of the footnotes to the consolidated financial statements.

⁽¹⁾ Obtained via the OMNI acquisition.

⁽²⁾ Obtained via the American Horizons acquisition.

⁽³⁾  Subject to regulatory requirements.

⁽⁴⁾ The interest rate on the Company’s junior subordinated debt is indexed to LIBOR and is based on the 3-month LIBOR rate. At December 31, 2012, the 3-month LIBOR rate was 0.31%.

Shareholders’ Equity

Shareholders’ equity provides a source of permanent funding, allows for future growth and provides the Company with a cushion to withstand unforeseen adverse developments. At December 31, 2012, shareholders’ equity totaled $1.5 billion, an increase of $47.2 million, or 3.2%, compared to December 31, 2011. The following table details the changes in shareholders’ equity during the twelve months ended December 31, 2012.

Share-based compensation cost		9,907
Balance, end of period	$	1,529,868

In addition to the total comprehensive income earned during 2012 of $76.4 million, the increase in total shareholders’ equity was a result of the issuance of 754,334 shares of the Company’s common stock on July 31, 2012 to acquire all of the outstanding common stock of the former Florida Gulf shareholders. The increases were partially offset by dividend payments to common shareholders of $40.1 million in the current period, or $1.36 per common share. The Company paid dividends in all four quarters of 2012 that resulted in a payout to shareholders of over 52% of net income earned during the year.

In October 2011, the Board of Directors authorized the repurchase of up to 900,000 shares of common stock. The following table details these purchases during 2012 and is based on the settlement date of the transactions. The average price paid per share includes commissions paid. No shares were repurchased during the months not presented in the table.

CAPITAL RESOURCES

Federal regulations impose minimum regulatory capital requirements on all institutions with deposits insured by the Federal Deposit Insurance Corporation. The Federal Reserve Board (“FRB”) imposes similar capital regulations on bank holding companies. Compliance with bank and bank holding company regulatory capital requirements, which include leverage and risk-based capital guidelines, are monitored by the Company on an ongoing basis. Under the risk-based capital method, a risk weight is assigned to balance sheet and off-balance sheet items based on regulatory guidelines. At December 31, 2012, the Company exceeded all regulatory capital ratios.

At the end of 2012, the Company’s regulatory capital ratios and those of IBERIABANK were in excess of the levels established for “well-capitalized” institutions as well, as shown in the following table and chart.

TABLE 24—REGULATORY CAPITAL RATIOS

In June 2012, the FRB approved three related notices of proposed rulemaking (the “NPRs”) relating to implementation of minimum capital requirements and a capital conservation buffer reflecting requirements of the Dodd-Frank Wall Street Reform and Consumer Protection Act (“Dodd-Frank Act”) and the Basel III international capital standards. The three NPRs are expected to be published jointly by the Federal Reserve, the FDIC, and the Office of the Comptroller of Currency after each agency has completed its approval process. If approved as proposed, the NPRs would be effective over a phased-in period from 2013 to 2019. The Company is in the process of evaluating the impact of the proposed rules on the Company and IBERIABANK.

For additional information on the Company’s capital ratios, see Note 18 to the consolidated financial statements.

RESULTS OF OPERATIONS

The Company reported income available to common shareholders of $76.4 million, $53.5 million, and $48.8 million for the years ended December 31, 2012, 2011, and 2010, respectively. Earnings per share (“EPS”) on a diluted basis were $2.59 for 2012, $1.87 for 2011, and $1.88 for 2010. During 2012, net interest income increased $43.5 million, or 12.9%, over 2011, as interest income increased $24.9 million or 5.9%, and interest expense decreased $18.6 million, or 22.7%. Net interest income increased as a result of additional customer loan volume in 2012, resulting from both acquisition and organic growth. Income available to common shareholders was also positively

impacted by a $5.2 million decrease in the Company’s provision for credit losses, but was negatively impacted by a $58.5 million increase in noninterest expenses, the drivers of which are discussed below in the “Noninterest Expense” section of the discussion.

The increase in income before income taxes contributed to an increase in income tax expense of $11.5 million in 2012 over 2011. Cash earnings, defined as net income before the net of tax amortization of acquisition intangibles, amounted to $79.7 million, $56.9 million, and $52.0 million for the years ended December 31, 2012, 2011, and 2010, respectively.

The following discussion provides additional information on the Company’s operating results for the years ended December 31, 2012, 2011, and 2010, segregated by major income statement caption.

Net Interest Income

Net interest income is the difference between interest realized on earning assets and interest paid on interest-bearing liabilities and is also the driver of core earnings. As such, it is subject to constant scrutiny by management. The rate of return and relative risk associated with earning assets are weighed to determine the appropriateness and mix of earning assets. Additionally, the need for lower cost funding sources is weighed against relationships with clients and future growth requirements. The Company’s net interest spread, which is the difference between the yields earned on average earning assets and the rates paid on average interest-bearing liabilities, was 3.43%, 3.34%, and 2.84% during the years ended December 31, 2012, 2011, and 2010, respectively. The Company’s net interest margin on a taxable equivalent (“TE”) basis, which is net interest income (TE) as a percentage of average earning assets, was 3.58%, 3.51%, and 3.05% for the same periods.

Net interest income increased $43.5 million, or 12.9%, in 2012 when compared to 2011, to $381.8 million from $338.3 million. The improvement in net interest income was the result of a $1.1 billion increase in average earning assets and a decrease in the average cost of interest-bearing liabilities of 28 basis points, but was offset by a 7.6% increase in the average balance of interest-bearing liabilities and a 19 basis point decrease in earning asset yield. The average balance sheet growth over the past twelve months is primarily a result of growth in both the Company’s earning assets and noninterest-bearing deposits, due to both acquisition-related growth from Florida Gulf in the third quarter of 2012 and organic growth in the Company’s balance sheet.

Net interest income increased $56.6 million, or 20.1%, in 2011 to $338.3 million from $281.6 million in 2010. The improvement in net interest income was the result of a $403.9 million increase in average earning assets, an eight basis point increase in the yield on average earning assets, and a decrease in the average rate paid on interest-bearing liabilities of 42 basis points. Balance sheet growth in 2011 was primarily a result of the Company’s OMNI and Cameron acquisitions.

Average loans made up 72.4% and 68.9% of average earning assets in 2012 and 2011, respectively. Average loans increased $1.1 billion, or 16.4%, since December 31, 2011, and was the result of loan growth in the Company’s non-covered loan portfolio. Investment securities made up 18.1% of average earning assets during 2012, compared to 20.8% during 2011. Over the past year, management has focused efforts to reduce its lower-yielding excess liquidity (defined as fed funds sold and interest-bearing cash) by investing in higher-yielding loans and investment securities, as well as paying down its short- and long-term debt in efforts to improve net interest income. Other significant components of earning assets during 2012 included the Company’s FDIC loss share receivable (4.5% of average earning assets) and excess liquidity (3.0% of average earning assets). During 2011, the Company’s FDIC loss share receivable was 6.6% of average earning assets, with excess liquidity accounting for 2.2% of average earning assets.

Average interest-bearing deposits made up 91.8% of average interest-bearing liabilities during 2012, down from 91.9% during 2011. Average short- and long-term borrowings made up 3.3% and 4.9% of average interest-bearing liabilities in 2012, respectively, compared to 2.7% and 5.4% during the year ended December 31, 2011.

The following table sets forth, for the periods indicated, information regarding (i) the total dollar amount of interest income of the Company from earning assets and the resultant average yields; (ii) the total dollar amount of interest expense on interest-bearing liabilities and the resultant average rates; (iii) net interest income; (iv) net interest spread; and (v) net interest margin. Information is based on average daily balances during the indicated periods. Investment security market value adjustments and trade-date accounting adjustments are not considered to be earning assets and, as such, the net effect is included in nonearning assets. Taxable equivalent yields are calculated using a marginal tax rate of 35%.

Interest income includes interest income earned on earning assets as well as applicable loan fees earned. Interest income that would have been earned on nonaccrual loans had they been on accrual status is not included in the data reported above.

The decrease in yield on total earning assets between 2012 and 2011 was driven by lower yields on the Company’s consumer loan and investment security portfolios, as well as a higher amortization of the Company’s FDIC loss share receivable (that results in a negative yield for this asset).

For the year ended December 31, 2012, the increase in the average balance of the Company’s earning assets drove the $24.9 million increase in interest income, as average balance increases in the largest components of earning assets offset rate decreases. Average loan balances increased $1.1 billion, or 16.4%, over 2011 and can be attributed to the non-covered loan growth since December 31, 2011, both from the Florida Gulf acquisition and organic non-covered loan growth. Covered loan yields increased 30 basis points and also contributed to the additional income generated during the current year. The amortization of the loss share receivable was $118.1 million in 2012, an increase of $46.0 million that can be attributed to the related increase in expected cash flow from the covered assets. As expected cash flow on the covered loan and OREO portfolios increases, the carrying value of the FDIC loss share receivable decreases, with the difference recorded as an adjustment to earnings. Interest income growth, however, was slowed in the current year by a decrease in the yield on the Company’s non-covered loan portfolio of 30 basis points to 4.63%. The total yield of the loan portfolio when including the loss share receivable was 4.77%, 19 basis points lower than the same period of 2011, and offset the income earned on loan volume increases over 2011.

Interest income growth was also slowed by a 34 basis point decrease in the yield on the Company’s investment securities. Average investment securities also decreased $76.3 million during the years ended December 31, 2012 when compared to the same period of 2011, as the Company offset the acquired investments from Florida Gulf with sales of investment securities and generally did not invest the funds received from sales and maturities in additional investment securities. Despite the decrease in yield, investment securities yielded 2.31% during the current year, well above the yield on interest-bearing cash and fed funds sold of 0.25% for the same period.

Driven by a decrease of 28 basis points in the rate paid on interest-bearing liabilities during the current year, interest expense decreased $18.6 million, or 22.7%, from 2011. Despite an increase of $559.2 million in average interest-bearing deposits (mostly a result of acquired Florida Gulf deposits), interest expense on the Company’s deposits decreased 30.0%, or $21.2 million, from 2011, as the average rate paid on these deposits decreased to 0.62% for 2012, a 33 basis point drop. Higher-yielding time deposits across many markets either matured or were repriced during 2012, driving the expense and rate decreases. The $2.5 million increase in interest expense on the Company’s long-term debt was a result of a rate increase of 62 basis points, as average long-term debt decreased $8.9 million, or 2.0%, from 2011.

In 2011, the increase in the Company’s average earning assets drove the increase in interest income over 2010, as average balance increases in the commercial and consumer loan portfolios, as well as a balance increase in the investment portfolio, offset rate decreases across multiple portfolios. Average loan balances increased 17.2% over 2010 and can be attributed to the non-covered loan growth, both from the OMNI and Cameron acquisitions and organic non-covered loan growth. Loan yields improved 29 basis points, which also contributed to the increase in interest income over 2010.

Average investment securities increased $308.5 million during 2011 when compared to the same period of 2010, as the Company acquired investments from OMNI and Cameron and purchased higher-yielding investment securities with available cash to improve earning asset yields.

Driven by a decrease of 42 basis points in the rate paid on interest-bearing liabilities during 2011, interest expense decreased 28.5% from 2010. Despite an increase of $260.8 million in average interest-bearing deposits, interest expense on the Company’s deposits decreased $25.2 million from 2010, as the average rate paid on these deposits decreased 38 basis points to 0.95% for the twelve months of 2011. Higher-yielding deposits acquired from the 2009 and 2010 Alabama and Florida acquisitions either matured or were repriced during 2011, contributing to the basis point decrease. The decrease in interest expense on the Company’s long-term debt was a result of a $153.9 million decrease in average long-term debt from 2010 and a rate decrease of 57 basis points.

Provision for Credit Losses

Management of the Company assesses the allowance for credit losses monthly and will make provisions for credit losses as deemed appropriate in order to maintain the appropriateness of the allowance for credit losses. Increases in the allowance for credit losses are achieved through provisions for credit losses that are charged against income. Adjustments to the allowance may also result from credit quality changes associated with loans acquired.

On a consolidated basis, the Company recorded a provision for credit losses of $20.7 million for the year ended December 31, 2012, a $5.2 million, or 20.1%, decrease from the provision recorded for the same period of 2011. The Company’s provision in 2012 primarily included a provision related to non-acquisition loan growth and provisions for changes in expected cash flows on the Company’s acquired loan and covered loan portfolios of $9.8 million and $7.1 million, respectively. The Company’s total provision was limited in

2012 by an improvement in legacy portfolio asset quality over the past 12 months, as multi-year net charge-off trends in this portfolio continue to show signs of improvement.

Non-covered loans past due totaled $127.9 million at December 31, 2012, an increase of $7.1 million from December 31, 2011. However, excluding the past due loans acquired from Florida Gulf, total non-covered past due loans decreased $6.2 million, or 5.1%. Past due loans, including nonaccrual loans, were 1.71% of total loans (before acquired loan discount adjustments) at the end of 2012, a 26 basis point decrease from December 31, 2011. Excluding the acquired loans, loans past due were 0.92% of total loans at December 31, 2012, an improvement of 30 basis points from year-end 2011.

Net charge-offs on the consolidated portfolio were $4.8 million year-to-date excluding $14.9 million recorded in 2012 on a limited number of loan pool closures, a net charge-off percentage of 0.06%, six basis points lower than the 0.12% in 2011. The net charge-offs were a result of $10.1 million in charge-offs and $5.3 million in recoveries.

The Company believes the allowance was appropriate at December 31, 2012 and 2011 to cover probable losses in the Company’s loan portfolio. The allowance for credit losses as a percentage of outstanding loans, net of unearned income, increased 34 basis points from 2.62% at December 31, 2011 to 2.96% at December 31, 2012.

The Company’s allowance for the non-covered portfolio was 1.12% of non-covered loans at December 31, 2012 and 1.40% at December 31, 2011. On the same basis, the Company’s allowance at December 31, 2012 was 81.3% of total nonperforming loans, which compares favorably to 80.3% of nonperforming loans at the end of 2011. The Company’s provision for credit losses covered net charge-offs 2.9 times in 2012.

Noninterest Income

The Company’s operating results included noninterest income of $176.0 million in 2012, $131.9 million in 2011, and $133.9 million in 2010. The growth of the Company’s noninterest income has been a management focus in the current year in response to a challenging interest rate environment. As a result, the Company has continued to increase its investment in these revenue streams, primarily its wealth management, trust, and brokerage businesses, in order to improve its noninterest income. Noninterest income as a percentage of total gross revenue (defined as total interest and noninterest income) during 2012 increased to 28.3% compared to 23.9% of total gross revenue in 2011 and 25.2% in 2010.

The following table illustrates the primary components of noninterest income for the years indicated.

⁽¹⁾  Gain on sale of investments includes gains on the calls of held to maturity securities of $35,000, $53,000, and $80,000 for the years ended December 31, 2012, 2011, and 2010, respectively.

Service charges on deposit accounts increased $0.9 million in 2012 from the prior year, and $1.5 million between 2010 and 2011, due primarily to an increase in service charge fees and analysis service charges. Customers increased as a result of the Florida Gulf acquisition and new branch openings since 2011, as well as the OMNI and Cameron acquisitions in 2011.

ATM/debit card fee income decreased $2.0 million in 2012 from 2011 primarily due to a decrease in interchange fee income. Card income was negatively impacted in 2012 by the reordering of the posting sequence for electronic debit transactions associated with the settlement of the Company’s class action lawsuit and the implementation of Durbin amendment provisions of the Dodd-Frank Act.

Offsetting these negative factors were increases in transaction volume from the expanded cardholder base and in usage by customers. ATM/debit card fee income increased $0.9 million in 2011 over 2010 and was also primarily the result of the Company’s expanded cardholder base and customer usage.

Income earned from bank owned life insurance increased $0.4 million in 2012 when compared to 2011 and increased $0.2 million from 2010 to 2011, consistent with market performance and current yields. The additional policies acquired from OMNI and Cameron in the second quarter of 2011 contributed to higher revenue over 2010.

IMC had its most successful year to-date in terms of production and sales volume, which drove the $32.9 million increase in mortgage loan income over 2011. Sales proceeds increased $751.3 million, or 45.9%, in the current year. In addition to the volume increase, a higher margin on the sales of mortgage loans led to higher income in 2012. Average margin on the sale of mortgage loans was 3.05% during 2012, a 28 basis point increase over the average margin in 2011. Gains on the sales of mortgage loans decreased $2.8 million in 2011 from 2010 as a result of a decrease in overall sales volume. Sales proceeds decreased $165.8 million, or 9.2%, from 2010. Partially offsetting the volume decrease was improved margin on the sales of mortgage loan originations, fueled in part by loan refinancing.

The Company recorded a net gain on the sale of assets during 2012 of less than $0.1 million as a result of the disposal of equipment no longer in use. The $0.9 million gain on the sale of assets during 2011 was a result of the sale of tax credits and the disposal of former bank property and equipment no longer in use. A $0.1 million loss on sales of assets was recorded in 2010. The loss in 2010 was primarily from the disposal of automobiles at the former Orion branches, as well as the sale of a modular branch building.

Changes in the sales volume of investment securities primarily drove the change in the gains recorded on these sales. Gains on investment sales increased $0.3 million in 2012 when compared to 2011, but decreased $1.8 million between 2010 and 2011. Gains were recorded on the sale of $150.5 million in available-for-sale securities and the call of $43.5 million of held-to-maturity investments for the twelve months of 2012, compared to the sale of $126.9 million in securities during 2011 and $243.8 million during 2010.

Title income increased $2.9 million during 2012 when compared to the prior year and was the result of a favorable mortgage business environment, fueled by low mortgage interest rates. Title income remained steady between 2011 and 2010.

Similar to IMC, the Company’s wealth management subsidiaries had very successful revenue growth, as total broker commissions increased $3.2 million compared to 2011, a result of the Company’s expanded client base and service offering. The Company’s other wealth management income, which includes research income, syndicate deals, and investment banking management and underwriting fees, increased $0.8 million, or 8.4%, over the comparable 2011 period. Sales and trading commissions increased $2.4 million, or 348.3%, from 2011. Broker commissions increased $2.7 million, or 35.8%, from 2010 to 2011, a result of the Company’s expanded client base, including the Company’s expansion in Arkansas and Florida in 2011.

Other noninterest income increased $5.9 million in 2012 when compared to 2011. Other noninterest income in 2012 was positively impacted by higher trust department income (an increase of $1.9 million, or 75.7%), which can be attributed to the increased customer base and growth of the business. Income was also positively affected by additional earnings on the Company’s deferred compensation assets and earnings on the Company’s investment in new market tax credits. Deferred compensation earnings increased $0.7 million during 2012, while income from new market tax credits increased $0.5 million, or 18.2%, from 2011. The Company also recorded a $2.2 million gain on the redemption of a business investment acquired from OMNI in 2011. Other noninterest income remained consistent for the twelve months of 2011 when compared to the same period of 2010. Other noninterest income in 2011 was positively impacted by higher trust department income, also a result of the increased customer base and growth of the business during that year, but was negatively affected by lower earnings on the Company’s deferred compensation assets.

Noninterest Expense

The Company’s results included noninterest expenses of $432.2 million, $373.7 million, and $304.2 million for 2012, 2011, and 2010, respectively. Ongoing attention to expense control is part of the Company’s corporate culture. However, the Company’s continued focus on growth through new branches, acquisitions, product expansion, and operational investments have caused related increases in several components of noninterest expense. Since the end of 2011, the Company acquired eight branches in the Florida Gulf acquisition and opened an additional 14 branches. These additions were offset by the closing or consolidation of 11 branches.

Also affecting noninterest expense during the current year were the Company’s expenses incurred as part of merger-related activities and expenses incurred as part of multiple ongoing process improvement projects that are designed to enhance the operational effectiveness and profitability of the Company. The projects’ costs have been incurred in the current year to improve overall organizational profitability across multiple markets, product lines, and departments, the benefits of which the Company expects to realize in future periods.

The following table illustrates the primary components of noninterest expense for the years indicated.

Salaries and employee benefits increased $40.0 million in 2012 when compared to 2011. The increase was primarily the result of increased staffing due to the growth of the Company. Current year expenses include the full year impact of additional OMNI and Cameron personnel, as well as personnel from Florida Gulf and the Company’s new branches for a portion of the year. Full-time equivalent employees increased to almost 2,700 at the end of 2012, a 4.5% increase from the end of 2011. The Company added these employees as part of the Florida Gulf acquisition, but the increase includes additional revenue-producing positions at IBERIABANK and its mortgage origination subsidiary.

Total employee compensation increased $35.5 million, or 20.5%, while related employee benefits increased 20.6% to $29.3 million for the year ended December 31, 2012. The increase in compensation is a result of the increase in headcount due to the growth of the Company, but is also a result of a full year of compensation expense from OMNI and Cameron employees in 2012. Employee compensation in 2012 included $2.1 million of additional share-based incentive compensation due to additional restricted stock, phantom stock, and option grants in 2012. Employee compensation also includes commissions and production-related bonuses which increased $2.3 million, or 79.3% from 2011, consistent with the increases in income from these product lines.

Employee benefits include payroll taxes, medical and dental insurance expenses, and retirement contributions. The increase in these benefits was a result of $2.7 million in additional hospitalization expense during 2012, partially from an increase in headcount and partially from higher claims processed in the current year. Employee benefits also included a $2.1 million, or 20.5%, increase in total payroll taxes in 2012.

From 2010 to 2011, salaries and employee benefits increased $32.3 million. Similar to the change in the current year, the increase was primarily the result of increased staffing due to the growth of the Company. Expenses in 2011 included the full impact of additional Sterling personnel, as well as salaries and employee benefits expense and severance expense from the former OMNI and Cameron employees. Salaries and employee benefits in 2011 also included increased share-based incentive compensation due to additional restricted stock, phantom stock, and option grants in 2011.

Occupancy and equipment expenses were up $5.1 million, or 10.2%, from 2011. These increased costs include repairs and maintenance on branches, depreciation, utilities, rentals and property taxes. Merger-related expenses from the Florida Gulf acquisition in 2012 were $0.2 million. Excluding the merger-related occupancy and equipment costs, occupancy and equipment expense was $10.0 million, or 22.5%, higher than in 2011, which is consistent with the increase in the size of the Company. Depreciation expense increased $4.9 million, or 36.1%. The higher depreciation expense is a result of additional branches opened and the Florida Gulf branches, but also includes accelerated depreciation on the Company’s ten branches that closed in 2012. Equipment rental (mostly ATMs), building rent, and property taxes increased $1.5 million, $0.8 million, and $0.8 million, respectively, and account for most of the remaining increase over 2011.

Occupancy and equipment expense increased $15.8 million for the twelve months of 2011 over the comparable 2010 period due primarily to the cost of facilities associated with the Company’s expansion. Occupancy expense for 2011 include $5.2 million of

acquisition-related expenses during 2011, which include the full expensing of vacated lease liabilities acquired from OMNI and Cameron. Similar expenses were only $0.5 million in 2010.

Franchise and shares tax expense decreased $0.4 million as a result of a $0.6 million decrease in share tax expense in 2012 based on the Company’s equity split between the states it operates in. As the Company’s footprint expands, the assessment base for Louisiana shares tax decreases. Franchise and shares tax expense increased $1.5 million during 2011 over 2010, a result of a higher assessment base for the shares tax calculation for IBERIABANK. The higher assessment resulted from increased equity at IBERIABANK at the end of December.

The Company’s expansion from the OMNI, Cameron, and Florida Gulf acquisitions, as well as new branches opened since the end of 2011, led to a $1.2 million increase in communication and delivery expenses. The increase was the result of an increase in data line and telephone expenses. The increase was consistent with the expansion of the Company’s footprint.

In 2012, marketing and business development expenses increased $2.8 million over 2011 as a result of additional expenses associated with business development and community relations. The Company continues to aggressively market itself in its newer markets, including those in Florida, Alabama, and Texas. Advertising and related expenses increased $1.6 million, or 36.4%, from the prior year as a result of additional direct mail, digital media, and newspaper advertising. In addition to the Company’s general advertising in its core markets, additional advertising expenses during 2012 focused on the Company’s 125^th anniversary campaign and included promotional giveaways and focused branch events. In 2012, business development expenses increased $1.2 million, or 22.6%, with the increase not only the result of the Company’s anniversary campaign, but also its focused efforts in community reinvestment activities. From 2010 to 2011, marketing and business development expenses increased $3.5 million as a result of additional expenses associated with business development and community relations in the Company’s Florida and Alabama markets. During 2011, the Company incurred acquisition-related costs of $0.8 million related to the Company’s OMNI and Cameron acquisitions. The $0.8 million is an increase of $0.4 million, or 89.3%, from the same twelve months of 2010.

Data processing expenses increased $1.1 million in 2012 as the Company incurred additional processing charges during 2012 as the Company increases its branch network and system capabilities and software amortization from system enhancements and upgrades. Merger-related data processing expenses, however, decreased $2.7 million, or 66.4%, from 2011. The Company’s merger-related expenses in 2011 included two system conversions (OMNI and Cameron). Excluding these merger-related expenses, data processing expenses, which include computer maintenance and software amortization, increased $3.8 million, or 36.2% between years.

The core deposit intangible assets created in the OMNI and Cameron acquisitions in 2011 contributed to the minimal increase in the Company’s amortization expense over the prior year. The core deposit intangible assets created in the Sterling, OMNI, and Cameron acquisitions in 2010 and 2011 contributed to the $0.2 million increase in amortization expense of the Company’s intangible assets in 2011 when compared to 2010.

Due to the growth of the Company over the past 12 months, professional services expense in 2012 was $6.0 million higher than in 2011. The continued expansion of the size and breadth of Company’s operations requires additional expenditures for legal services, consulting engagements, exam and supervisory review, and audit services. More specifically, legal expenses increased $1.8 million in the current year. Legal expenses include those around general matters, litigation, settlement, and collection efforts. The Company also incurred merger-related legal expenses of $0.5 million during 2012.

The Company’s efforts to improve various Company and business-line specific processes drove the increase in total consulting expenses of $4.7 million over 2011. The Company expects to see the benefit of these improvements in future periods. Offsetting the increase was a decrease in other merger-related professional services, which include exam, audit, and other professional services, of $2.4 million in 2012 when compared to 2011.

From 2010 to 2011, professional services expenses increased $1.6 million, the result of legal, audit and consulting expenses incurred as part of the Company’s OMNI and Cameron acquisitions during 2011. Merger-related professional services were $3.4 million during 2011.

Net costs of OREO properties decreased $3.7 million in 2012 from 2011, as write-downs taken on OREO properties decreased $0.8 million, or 11.6%, the gains on the sale of properties increased $3.5 million, and property taxes paid on held properties decreased $0.2 million, or 12.9%. Offsetting these changes were additional insurance and other expenses on these properties, driven primarily by the additional properties in the portfolio during the current year. The increased expenses were offset partially by an increase in the income earned on the properties during 2012. From 2010 to 2011, net costs of OREO properties increased $6.8 million, as write-downs taken on OREO properties increased $4.3 million while gains on the sale of OREO properties for 2011 decreased $1.0 million, or 41.5%, from the comparable twelve months of 2010.

Credit and loan related expenses increased $2.7 million from 2011 to 2012, and $2.6 million between 2010 and 2011. With the expansion of the Company’s loan portfolio, expenses incurred for appraisal, inspection, underwriting, certification, and collections have also increased. Between 2010 and 2011, the increase was also due to the expanded size of the loan portfolio and the number of loans

with noted credit issues. The increase in credit-related expenses stemmed primarily from the Company’s covered loan portfolio. The credit quality issues inherent in the portfolio covered by loss share agreements with the FDIC drove appraisal and inspection, collections, and credit bureau expenses higher.

Insurance expenses increased $0.7 million in 2012, primarily as a result of additional deposit insurance in the current year. As the Company’s deposit base grows, the Company’s assessment of deposit insurance from the FDIC will also increase. The increase in the assessment in 2012 stemmed from deposit growth, and was not a result of a change in the Company’s assessment rate used by the FDIC to calculate deposit insurance.

In 2012, travel and entertainment expenses increased $1.9 million from 2011 and $0.6 million between 2010 and 2011. Travel costs have increased steadily as the Company expands its branch network and number of locations. Travel expenses drove the increase over 2011, as mileage, lodging, and flight costs have increased due to the number of employees traveling, the expanded size of the Company’s footprint, and a general increase in the cost of travel.

Other noninterest expenses in 2012 increased $1.0 million over the twelve months of 2011 and was primarily the result of an increase in employee development and credit card expenses for the year. The additional costs were a result of the increased employee and client base. Other noninterest expenses in 2012 include impairment write-downs of $3.5 million on certain branch buildings and equipment based on updated appraisals on the properties. The branches were reviewed for impairment as part of the Company’s announced branch closures and written down to their estimated fair values during the second and third quarters of 2012.

In 2011, other noninterest expenses increased $2.4 million over 2010. Outsourced operations increased $1.6 million from 2010 to 2011 at the Company’s wealth management subsidiary as operating activities increased in the latter part of 2010 and into 2011. The most significant reason for the increase in other operating expenses over 2010 was a result of a $2.6 million settlement liability recorded in the Company’s consolidated financial statements for the year ended December 31, 2011, which led to the $1.0 million increase in the total costs of errors, fines, and losses over 2010. The settlement was related to two class action lawsuits related to overdraft fees for electronic transfers in a high to low processing sequence on the posting of items for processing. Offsetting these increases was a reduction in credit card expenses of $0.8 million.

Income Taxes

For the years ended December 31, 2012, 2011, and 2010, the Company incurred income tax expense of $28.5 million, $17.0 million, and $20.0 million, respectively. The Company’s effective tax rate for those periods was 27.2%, 24.1%, and 29.1%, respectively. The difference between the effective tax rate and the statutory tax rate primarily relates to variances in items that are non-taxable or non-deductible, primarily the effect of tax-exempt income, the non-deductibility of part of the amortization of acquisition intangibles, and various tax credits. The Company’s consolidated effective tax rates were also positively impacted by the Company’s ICP subsidiary, as well as the holding company, as these entities had income tax benefits during the three years from net losses. The effective tax rate on these entities is higher than IBERIABANK’s effective tax rate (which is affected by the various tax credits).

The consolidated effective tax rate in 2012 has increased when compared to the prior year. The difference in the effective tax rates for the periods presented is primarily the result of the relative tax-exempt interest income levels during the respective periods for each of the Company’s subsidiaries. The tax rate for the current year is higher than in 2011 as a result of the effect of the change in IBERIABANK’s effective tax rate. The increase in income before taxes at IBERIABANK in the current year results in a higher effective tax rate, as the effect of nontaxable income and other temporary tax differences is diluted. In addition, in the current year, a larger percentage of the year-to-date income before taxes was generated in Alabama, Florida, and Arkansas, which have higher effective rates than Louisiana and Texas, the Company’s other primary states with business operations. IBERIABANK’s effective tax rate was 30.9% and 29.8% for 2012 and 2011, respectively.

For more information on the Company’s income taxes and effective tax rates, see Note 16 of the consolidated financial statements.

LIQUIDITY AND OTHER OFF-BALANCE SHEET ACTIVITIES

The Company’s liquidity, represented by cash and cash equivalents, as well as available off balance sheet borrowing sources, is a product of its operating, investing and financing activities. The Company manages its liquidity with the objective of maintaining sufficient funds to respond to the predicted needs of depositors and borrowers and to take advantage of investments in earning assets and other earnings enhancement opportunities. The primary sources of funds for the Company are deposits, borrowings, repayments and maturities of loans and investment securities, securities sold under agreements to repurchase, as well as funds provided from operations and to a lesser extent off balance sheet borrowing sources. Certificates of deposit scheduled to mature in one year or less at December 31, 2012 totaled $1.5 billion. Based on past experience, management believes that a significant portion of maturing deposits will remain with the Company. Additionally, the majority of the investment security portfolio is classified by the Company as available-for-sale which provides the ability to liquidate unencumbered securities as needed. Of the $2.0 billion in the investment securities portfolio, $237.2 million is unencumbered and $1.7 billion has been pledged to support repurchase transactions, public funds deposits and certain long

term borrowings. Due to the relatively short implied duration of the investment security portfolio, the Company continues to experience significant cash inflows on a regular basis.

Net cash inflows totaled $397.7 million during 2012, an increase of $162.2 million from net cash inflows of $235.5 million during the year ended December 31, 2011.

The following table summarizes the Company’s cash flows for the years ended December 31^st for the periods indicated. For the 2011 and 2010 periods, cash flows from operations and investing activities have been restated from previously issued amounts to reflect the correction of an error in these line items. For a description of the Company’s determination to correct its consolidated statements of cash flows for those years, see Note 1 to the consolidated financial statements, which provides more information on the nature of these corrections.

TABLE 30—CASH FLOW ACTIVITY BY TYPE

(Dollars in thousands)	2012			2011		2010
Cash flow (used in) provided by operations	$	(12,188	)	$	15,758	$	214,646
Cash flow (used in) provided by investing activities		(527,676	)		25,732		(57,305	)
Cash flow provided by financing activities		937,545			194,028		5,040
Net increase in cash and cash equivalents	$	397,681		$	235,518	$	162,381

The Company had operating cash outflow of $12.2 million for the year ended December 31, 2012, $27.9 million more than cash provided by operations for the same period of 2011. Operating cash flow in the current year was negatively impacted by an increase in mortgage loan origination activity in the current year.

Cash flow from investing activities decreased $553.4 million during 2012 when compared to 2011. Funding loan growth and a decrease in net cash flow from investment securities drove the decrease in cash flow from 2011. Net cash flow from investment security activity decreased $267.7 million in 2012 as a result of a higher level of security purchases in 2012. Cash flow used to fund loan growth increased $309.9 million and also had a negative impact on the current period cash flow. Positively affecting cash flow in 2011 was the acquisition of $79.3 million in cash as part of the OMNI and Cameron acquisitions, $46.9 million higher than the net cash acquired from Florida Gulf in 2012.

Net financing cash flows, however, increased $743.5 million during the current year when compared to 2011, primarily due to an increase in cash from customer deposits that results in a $1.0 billion difference in net deposit cash flow between the two periods. Net cash outflow of $159.0 million from short-term borrowings and long-term debt in 2012 offset the cash inflow from deposits in the current year.

From 2010 to 2011, operating cash inflow of $15.8 million was $198.9 million less than for the twelve months of 2010. Operating cash flow in 2010 was negatively impacted by a decrease in net cash provided by mortgage loan sales. The operating cash flow in 2010 was positively affected by a decrease in other assets (primarily fed funds sold) from the prior year.

Cash flow from investing activities increased $83.0 million during 2011 when compared to 2010. Positively affecting cash flow was net cash received in excess of cash paid for acquisitions of $79.3 million, $55.2 million higher than in 2010, as well as proceeds from the disposition of OREO properties. Operating cash flow in 2011 was also positively affected by net cash inflow for investment security activity. 2011 net cash inflow from investment security activity was $353.7 million, $757.7 million higher than in 2010. Investing cash flow in 2011 was also negatively impacted by a decrease in reimbursements from the FDIC on assets covered by loss share agreements. Net cash flow from FDIC reimbursements decreased to $139.9 million in 2011, $299.0 million lower than the same period of 2010.

Net financing cash flows increased $189.0 million during 2011 when compared to 2010, primarily due to an increase in cash from customer deposits that results in an $87.3 million difference in net deposit cash flow between the two periods. Also contributing to the difference in financing cash flows between 2011 and 2010 was net cash received from short-term borrowings of $136.8 million in the current year, mostly from $192 million in FHLB advances outstanding at December 31, 2011. During 2010, the Company used available cash to significantly pay down outstanding short- and long-term debt. Total net repayments of debt in 2010 were $377.8 million, compared to net cash advances of $92.7 million in the twelve months of 2011.

Based on its available cash at December 31, 2012, the Company believes it has adequate liquidity to fund ongoing operations. The Company has adequate availability of funds from deposits, borrowings, repayments and maturities of loans and investment securities to provide the Company additional working capital if needed.

While scheduled cash flows from the amortization and maturities of loans and securities are relatively predictable sources of funds, deposit flows, prepayments of loan and investment securities, and draws on customer letters and lines of credit are greatly influenced by general interest rates, economic conditions, competition, and customer demand. The FHLB of Dallas provides an additional source of liquidity to make funds available for general requirements and also to assist with the variability of less predictable funding sources. At December 31, 2012, the Company had $233.8 million of outstanding long-term advances from the FHLB. There were no short-term FHLB advances outstanding at December 31, 2012. Additional advances available at December 31, 2012 from the FHLB amounted to $1.4 billion. The Company and IBERIABANK also have various funding arrangements with commercial banks providing up to $130.0 million in the form of federal funds and other lines of credit, and at December 31, 2012, there were no balances outstanding on these lines, and all of the funding was available to the Company.

Liquidity management is both a daily and long-term function of business management. Excess liquidity is generally invested in short-term investments such as overnight deposits. On a longer-term basis, the Company maintains a strategy of investing in various lending and investment security products. The Company uses its sources of funds primarily to meet its ongoing commitments and fund loan commitments. The Company has been able to generate sufficient cash through its deposits, as well as borrowings, and anticipates it will continue to have sufficient funds to meet its ongoing liquidity requirements.

In the normal course of business, the Company is a party to a number of activities that contain credit, market and operational risk that are not reflected in whole or in part in the Company’s consolidated financial statements. Such activities include traditional off-balance sheet credit-related financial instruments, commitments under operating leases and long-term debt. The Company provides customers with off-balance sheet credit support through loan commitments, lines of credit and standby letters of credit. Many of the unused commitments are expected to expire unused or be only partially used; therefore, the total amount of unused commitments does not necessarily represent future cash requirements. The Company anticipates it will continue to have sufficient funds together with available borrowings to meet its current commitments. At December 31, 2012, the Company’s approved loan commitments outstanding totaled $192.3 million. At the same date, commitments under unused lines of credit, including credit card lines, amounted to $2.4 billion. Included in these totals are commercial commitments amounting to $1.8 billion as shown in the following table.

TABLE 31—COMMERCIAL COMMITMENT EXPIRATION PER PERIOD

(Dollars in thousands)	Less Than 1 Year		1—3 Years		3—5 Years		Over 5 Years		Total
Unused commercial lines of credit	$	973,791	$	417,998	$	341,408	$	60,804	$	1,794,001

The Company has entered into a number of long-term leasing arrangements to support the ongoing activities of the Company. The required payments under such commitments and other debt commitments at December 31, 2012 are shown in the following table.

ASSET/ LIABILITY MANAGEMENT, MARKET RISK AND COUNTERPARTY CREDIT RISK

The principal objective of the Company’s asset and liability management function is to evaluate the interest rate risk included in certain balance sheet accounts, determine the appropriate level of risk given the Company’s business focus, operating environment, capital and liquidity requirements and performance objectives, establish prudent asset concentration guidelines and manage the risk consistent with Board approved guidelines. Through such management, the Company seeks to reduce the vulnerability of its operations to changes in interest rates. The Company’s actions in this regard are taken under the guidance of the Senior Management Planning Committee. The Senior Management Planning Committee normally meets monthly to review, among other things, the sensitivity of the Company’s assets and liabilities to interest rate changes, local and national market conditions and interest rates. In connection therewith, the Senior Management Planning Committee generally reviews the Company’s liquidity, cash flow needs, maturities of investments, deposits, borrowings and capital position.

The objective of interest rate risk management is to control the effects that interest rate fluctuations have on net interest income and on the net present value of the Company’s earning assets and interest-bearing liabilities. Management and the Board are responsible for managing interest rate risk and employing risk management policies that monitor and limit this exposure. Interest rate risk is measured using net interest income simulation and asset/liability net present value sensitivity analyses. The Company uses financial modeling to measure the impact of changes in interest rates on the net interest margin and predict market risk. Estimates are based upon numerous assumptions including the nature and timing of interest rate levels including yield curve shape, prepayments on loans and securities, deposit decay rates, pricing decisions on loans and deposits, reinvestment/replacement of asset and liability cash flows and others. These analyses provide a range of potential impacts on net interest income and portfolio equity caused by interest rate movements.

Included in the modeling are instantaneous parallel rate shift scenarios, which are utilized to establish exposure limits. These scenarios are known as “rate shocks” because all rates are modeled to change instantaneously by the indicated shock amount, rather than a gradual rate shift over a period of time that has traditionally been more realistic.

The Company’s interest rate risk model indicated that the Company was asset sensitive in terms of interest rate sensitivity. Based on the Company’s interest rate risk model at December 31, 2012, the table below illustrates the impact of an immediate and sustained 100 and 200 basis point increase or decrease in interest rates on net interest income.

TABLE 33—CHANGE IN NET INTEREST INCOME FROM INTEREST RATE CHANGES

Shift in Interest Rates (in bps)	% Change in Projected Net Interest Income
+200	7.9%
+100	3.8
- 100	-0.8
- 200	-1.7

The influence of using the forward curve as of December 31, 2012 as a basis for projecting the interest rate environment would approximate a 0.6% increase in net interest income. The computations of interest rate risk shown above do not necessarily include certain actions that management may undertake to manage this risk in response to anticipated changes in interest rates and other factors.

The interest rate environment is primarily a function of the monetary policy of the FRB. The principal tools of the FRB for implementing monetary policy are open market operations, or the purchases and sales of U.S. Treasury and federal agency securities. The FRB’s objective for open market operations has varied over the years, but the focus has gradually shifted toward attaining a specified level of the federal funds rate to achieve the long-run goals of price stability and sustainable economic growth. The federal funds rate is the basis for overnight funding and drives the short end of the yield curve. Longer maturities are influenced by FRB purchases and sales and also expectations of monetary policy going forward. In response to growing concerns about the banking industry and customer liquidity, the federal funds rate decreased seven times to a new all-time low of 0.25% at the end of 2008. The federal funds rate remained at 0.25% through 2012 and will remain at that rate through at least late 2014. The Company’s commercial loan portfolio is also impacted by fluctuations in the level of the London Interbank Borrowing Offered Rate (LIBOR), as a large portion of this portfolio reprices based on this index. The decrease in the federal funds, LIBOR, and U.S. Treasury rates have resulted in compressed net interest margin for the Company, as assets have repriced more quickly than the Company’s liabilities. Although management believes that the Company is not significantly affected by changes in interest rates over an extended period of time, any continued flattening of the yield curve will exert downward pressure on the net interest margin and net interest income. The table below presents the Company’s anticipated loan repricing over the next four quarters of 2013.

As part of its asset/liability management strategy, the Company has emphasized the origination of commercial and consumer loans, which typically have shorter terms than residential mortgage loans and/or adjustable or variable rates of interest. The majority of fixed-rate, long-term residential loans are sold in the secondary market to avoid assumption of the interest rate risk associated with longer duration assets in the current low rate environment. As of December 31, 2012, $4.2 billion, or 49.3%, of the Company’s total loan portfolio had adjustable interest rates. IBERIABANK had no significant concentration to any single loan component or industry segment.

The Company’s strategy with respect to liabilities in recent periods has been to emphasize transaction accounts, particularly noninterest or low interest-bearing transaction accounts, which are significantly less sensitive to changes in interest rates. At December 31, 2012, 80.0% of the Company’s deposits were in transaction and limited-transaction accounts, compared to 72.6% at December 31, 2011. Noninterest-bearing transaction accounts totaled 18.3% of total deposits at December 31, 2012, compared to 16.0% of total deposits at December 31, 2011.

The table below presents the Company’s anticipated time deposit repricing over the next four quarters of 2013.

Total time deposits	$	450,832	$	425,854	$	368,288	$	292,805	$	1,537,779

As part of an overall interest rate risk management strategy, derivative instruments may also be used as an efficient way to modify the repricing or maturity characteristics of on-balance sheet assets and liabilities. Management may from time to time engage in interest rate swaps to effectively manage interest rate risk. The interest rate swaps of the Company were executed to modify net interest sensitivity to levels deemed appropriate.

IMPACT OF INFLATION AND CHANGING PRICES

The consolidated financial statements and related financial data presented herein have been prepared in accordance with generally accepted accounting principles, which generally require the measurement of financial position and operating results in terms of historical dollars, without considering changes in relative purchasing power over time due to inflation. Unlike most industrial companies, the majority of the Company’s assets and liabilities are monetary in nature. As a result, interest rates generally have a more significant impact on the Company’s performance than does the effect of inflation. Although fluctuations in interest rates are neither completely predictable nor controllable, the Company regularly monitors its interest rate position and oversees its financial risk management by establishing policies and operating limits. Interest rates do not necessarily move in the same direction or in the same magnitude as the prices of goods and services, since such prices are affected by inflation to a larger extent than interest rates. Although not as critical to the banking industry as to other industries, inflationary factors may have some impact on the Company’s growth, earnings, total assets and capital levels. Management does not expect inflation to be a significant factor in 2013.

MANAGEMENT REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

To the Board of Directors of

IBERIABANK Corporation

The management of IBERIABANK Corporation (the “Company”) is responsible for establishing and maintaining adequate internal control over financial reporting. The Company’s internal control system was designed to provide reasonable assurance to the Company’s management and board of directors regarding the preparation and fair presentation of published financial statements.

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

The Company’s management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2012. In making this assessment, it used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control—Integrated Framework. Based on our assessment, management believes that, as of December 31, 2012, the Company’s internal control over financial reporting is effective based on those criteria.

The Company’s independent registered public accounting firm has also issued an attestation report on the effectiveness of the Company’s internal control over financial reporting as of December 31, 2012.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders

IBERIABANK Corporation

We have audited IBERIABANK Corporation’s internal control over financial reporting as of December 31, 2012, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). IBERIABANK Corporation’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, IBERIABANK Corporation maintained, in all material respects, effective internal control over financial reporting as of December 31, 2012, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of IBERIABANK Corporation as of December 31, 2012 and 2011, and the related consolidated statements of comprehensive income, shareholders’ equity, and cash flows for each of the three years in the period ended December 31, 2012 and our report dated March 1, 2013, expressed an unqualified opinion thereon.

Notes to Consolidated Financial Statements

NOTE 1 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include the accounts of IBERIABANK Corporation (the “Company”) and its wholly owned subsidiaries, IBERIABANK, Lenders Title Company (“LTC”), IBERIA Capital Partners LLC (“ICP”), IB Aircraft Holdings, LLC, IBERIA Asset Management Inc. (“IAM”), and IBERIA CDE, LLC (“CDE”). All significant intercompany balances and transactions have been eliminated in consolidation. All normal, recurring adjustments which, in the opinion of management are necessary for a fair presentation of the financial statements, have been included. Certain amounts reported in prior periods have been reclassified to conform to the current period presentation.

NATURE OF OPERATIONS

The Company offers commercial and retail banking products and services to customers throughout locations in six states through IBERIABANK. The Company also operates mortgage production offices in twelve states through IBERIABANK Mortgage Company (“IMC”), and offers a full line of title insurance and closing services throughout Arkansas and Louisiana through LTC and its subsidiaries. ICP provides equity research, institutional sales and trading, and corporate finance services. IB Aircraft Holdings, LLC owns a fractional share of an aircraft used by management of the Company and its subsidiaries. IAM provides wealth management and trust services for commercial and private banking clients. CDE is engaged in the purchase of tax credits.

CORRECTION OF AN ERROR IN THE FINANCIAL STATEMENTS

The Company has corrected its historical consolidated statements of cash flows for the years ended December 31, 2011 and 2010 for the miscalculation of certain activity between its operating and investing cash flows. The correction did not have an effect on the Company’s consolidated balance sheets, statements of comprehensive income, or statements of shareholders’ equity for those years. The error was identified in 2012 through the operation of the Company’s internal controls over financial reporting. Using accounting guidance provided in Accounting Standards Codification (“ASC”) Topic 250, the Company assessed these items and determined the error would be considered material to the consolidated statements of cash flows for the years ended December 31, 2011 and 2010. The error also impacts the consolidated statements of cash flows for each quarter in 2012 and 2011 as described in Note 26. As a result, the information included in these consolidated financial statements and footnotes includes the effect this correction has on the previously reported financial statements for those years.

The following table presents the effect this correction has on the Consolidated Statements of Cash Flows for the years ended December 31, 2011 and 2010.

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Material estimates that are susceptible to significant change in the near term are the allowance for credit losses, valuation of and accounting for loans covered by loss sharing arrangements with the FDIC and the related loss share receivable, valuation of and accounting for acquired loans, valuation of goodwill, intangible assets and other purchase accounting adjustments, and share-based compensation.

CONCENTRATION OF CREDIT RISKS

Most of the Company’s business activity is with customers located within the States of Louisiana, Florida, Arkansas, Alabama, Texas, and Tennessee. The Company’s lending activity is concentrated in its market areas in those states. The Company has emphasized originations of commercial loans and private banking loans, defined as loans to larger consumer clients. Repayments on loans are expected to come from cash flows of the borrower and/or guarantor. Losses on secured loans are limited by the value of the collateral upon default of the borrowers. The Company does not have any significant concentrations to any one industry or customer.

CASH AND CASH EQUIVALENTS

For purposes of presentation in the consolidated statements of cash flows, cash and cash equivalents are defined as cash, interest-bearing deposits and noninterest-bearing demand deposits at other financial institutions with original maturities less than three months. IBERIABANK may be required to maintain average balances on hand or with the Federal Reserve Bank to meet regulatory reserve and clearing requirements. At December 31, 2012 and 2011, the required reserve balances were $2,555,000 and $25,000, respectively. IBERIABANK had enough cash deposited with the Federal Reserve at December 31, 2012 and 2011 to cover the required reserve balance.

INVESTMENT SECURITIES

Debt securities that management has the ability and intent to hold to maturity are classified as held to maturity and carried at cost, adjusted for amortization of premiums and accretion of discounts using methods approximating the interest method. Securities not classified as held to maturity or trading, including equity securities with readily determinable fair values, are classified as available for sale and recorded at fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive income. Declines in the value of individual held to maturity and available for sale securities below their cost that are other than temporary are included in earnings as realized losses. In estimating other than temporary impairment losses, management considers 1) the length of time and the extent to which the fair value has been less than cost, 2) the financial condition and near-term prospects of the issuer, 3) the intent and ability of the Company to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value, and 4) for debt securities, the recovery of contractual principal and interest. Gains or losses on securities sold are recorded on the trade date, using the specific identification method.

LOANS HELD FOR SALE

Mortgage loans originated and intended for sale in the secondary market are carried at the lower of cost or estimated fair value. Net unrealized losses, if any, are recognized through a valuation allowance that is recorded as a charge to income. Loans held for sale have primarily been fixed rate single-family residential mortgage loans under contract to be sold in the secondary market. In most cases, loans in this category are sold within thirty days. These loans are generally sold with the mortgage servicing rights released. Buyers generally have recourse to return a purchased loan to the Company under limited circumstances. Recourse conditions may include early payment default, breach of representations or warranties, and documentation deficiencies. During 2012 and 2011, an insignificant number of loans were returned to the Company.

LOANS (EXCLUDING ACQUIRED LOANS)

The Company grants mortgage, commercial and consumer loans to customers. Except for loans acquired, loans receivable that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are stated at the unpaid principal balances, less the allowance for credit losses and net deferred loan origination fees and unearned discounts.

2

Interest income on loans is accrued over the term of the loans based on the principal balance outstanding. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield, using the effective interest method.

The accrual of interest on loans is discontinued at the time the loan is 90 days delinquent unless the credit is well-secured and in process of collection. Mortgage, credit card and other personal loans are typically charged down to net collateral value, less cost to sell, no later than 180 days past due. Past due status is based on the contractual terms of loans. In all cases, loans are placed on nonaccrual status or charged off at an earlier date if collection of principal or interest is considered doubtful.

The Company’s covered loan portfolio and non-covered loan portfolio, which are delineated between a) non-covered loans, excluding acquired loans, and b) acquired loans, are disaggregated into portfolio segments for purposes of determining the allowance for credit losses. The Company’s portfolio segments include commercial real estate, commercial business, mortgage, and consumer. The Company further disaggregates each commercial real estate, mortgage, and consumer portfolio segment into classes for purposes of monitoring and assessing credit quality based on certain risk characteristics. Classes within each commercial real estate portfolio segment include commercial real estate construction and commercial real estate – other. Classes within each mortgage portfolio segment include mortgage – prime and mortgage – subprime. Classes within each consumer portfolio segment include indirect auto, credit card, home equity, and consumer – other. Each commercial business portfolio segment is also considered a class.

Credit Quality

The Company utilizes an asset risk classification system in accordance with guidelines established by the Federal Reserve Board as part of its efforts to monitor commercial asset quality. “Special mention” loans are defined as loans where known information about possible credit problems of the borrower cause management to have some doubt as to the ability of these borrowers to comply with the present loan repayment terms and which may result in future disclosure of these loans as nonperforming. For assets with identified credit issues, the Company has two primary classifications for problem assets: “substandard” and “doubtful.” Substandard assets have one or more defined weaknesses and are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Doubtful assets have the weaknesses of substandard assets with the additional characteristic that the weaknesses make collection or liquidation in full satisfaction of the loan balance outstanding questionable and there is a high probability of loss based on currently existing facts, conditions and values. Loans classified as “Pass” do not meet the criteria set forth for special mention, substandard, or doubtful classification and are not considered criticized. Asset risk classifications are periodically reviewed and changed if, in the opinion of management, the risk profile of the customer has changed since the last review of the loan relationship.

A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. The impairment loss is measured on a loan by loan basis for commercial and construction loans by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral if the loan is collateral dependent.

In general, all interest accrued but not collected for loans that are placed on nonaccrual status or charged off is reversed against interest income. The interest on these loans is accounted for on the cash-basis method or cost-recovery method, until qualifying for a return to accrual status. Loans are returned to accrual status when all principal and interest amounts contractually due are brought current and future payments are reasonably assured.

Troubled Debt Restructurings

During the course of its lending operations, the Company periodically grants concessions to its customers in an attempt to protect as much of its investment as possible and minimize risk of loss. These concessions may include restructuring the terms of a customer loan to alleviate the burden of the customer’s near-term cash requirements. In order to be considered a troubled debt restructuring (“TDR”), the Company must conclude that the restructuring constitutes a concession and the customer is experiencing financial difficulties. The Company defines a concession to the customer as a modification of existing terms for economic or legal reasons that it would otherwise not consider. The concession is either granted through an agreement with the customer or is imposed by a court or law. Concessions include modifying original loan terms to reduce or defer cash payments required as part of the loan agreement, including but not limited to:

• a reduction of the stated interest rate for the remaining original life of the debt,

• extension of the maturity date or dates at a stated interest rate lower than the current market rate for new debt with similar risk characteristics,

• reduction of the face amount or maturity amount of the debt as stated in the agreement, or

• reduction of accrued interest receivable on the debt.

In its determination of whether the customer is experiencing financial difficulties, the Company considers numerous indicators, including, but not limited to:

• whether the customer is currently in default on its existing loan, or is in an economic position where it is probable the customer will be in default on its loan in the foreseeable future without a modification,

• whether the customer has declared or is in the process of declaring bankruptcy,

• whether there is substantial doubt about the customer’s ability to continue as a going concern,

• whether, based on its projections of the customer’s current capabilities, the Company believes the customer’s future cash flows will be insufficient to service the debt, including interest, in accordance with the contractual terms of the existing agreement for the foreseeable future, and

• whether, without modification, the customer cannot obtain sufficient funds from other sources at an effective interest rate equal to the current market rate for similar debt for a nontroubled debtor.

If the Company concludes that both a concession has been granted and the concession was granted to a customer experiencing financial difficulties, the Company identifies the loan as a TDR. For purposes of the determination of an allowance for credit losses for TDRs, the Company considers a loss probable on the loan, which is reviewed for specific impairment in accordance with the Company’s allowance

3

for loan loss methodology. If it is determined that losses are probable on such TDRs, either because of delinquency or other credit quality indicator, the Company establishes specific reserves for these loans. For additional information on the Company’s allowance for credit losses, see Note 7 to these consolidated financial statements.

ACQUIRED LOANS AND RELATED FDIC LOSS SHARE RECEIVABLE

The Company accounts for its acquisitions under the purchase method, where all identifiable assets acquired, including loans, are recorded at fair value. No allowance for credit losses related to the acquired loans is recorded on the acquisition date as the fair value of the loans acquired incorporates assumptions regarding credit risk.

Loans acquired are recorded at fair value in accordance with the fair value methodology consistent with the exit price concept and exclusive of the shared-loss agreements with the FDIC from certain of the Company’s acquisitions in 2010 and 2009. The fair value estimates associated with the loans include estimates related to discount rates, expected prepayments and the amount and timing of undiscounted expected principal, interest and other cash flows. Credit discounts are included in the determination of fair value: therefore, an allowance for credit losses is not recorded at the acquisition date. At the time of acquisition, the Company estimated the fair value of the total acquired loan portfolio by segregating the total portfolio into loan pools with similar characteristics, which included:

• whether the loan was performing according to contractual terms at the time of acquisition,

• the loan type based on regulatory reporting guidelines, namely whether the loan was a mortgage, consumer, or commercial loan

• the nature of collateral,

• the interest rate type, whether fixed or variable rate, and

• the loan payment type, primarily whether the loan was amortizing or interest-only.

From these pools, the Company used certain loan information, including outstanding principal balance, estimated expected losses, weighted average maturity, weighted average term to re-price (if a variable rate loan), weighted average margin, and weighted average interest rate to estimate the expected cash flow for each loan pool.

Acquired loans are evaluated at acquisition and classified as purchase impaired or purchased non-impaired. Purchased impaired loans reflect credit deterioration since origination to the extent that it is probable at the time of acquisition that the Company will be unable to collect all contractually required payments. For purchased impaired loans, expected cash flows at the acquisition date in excess of the fair value of loans are recorded as interest income over the life of the loans using a level yield method if the timing and amount of future cash flows is reasonably estimable.

Subsequent to acquisition, the Company performs cash flow re-estimations at least quarterly for each purchased impaired loan and/or loan pool. Increases in estimated cash flows above those expected at acquisition are recognized on a prospective basis as interest income over the remaining life of the pool. Decreases in expected cash flows subsequent to acquisition result in recognition of a provision for credit loss.

Acquired loans are placed on nonaccrual status when the Company cannot reasonably estimate cash flows on a loan or loan pool.

Pursuant to an AICPA letter dated December 18, 2009, the AICPA summarized the SEC staff’s view regarding the accounting in subsequent periods for discount accretion associated with loan receivables acquired in a business combination or asset purchase. Regarding the accounting for such loan receivables that, in the absence of further standard setting, the AICPA understands the SEC staff would not object to an accounting policy based on contractual cash flows (ASC Topic 310-20 approach) or an accounting policy based on expected cash flows (ASC 310-30 approach). The Company believes analogizing to ASC Topic 310-30 is the more appropriate option to follow in accounting for the fair value discount. However, in cases where a loan is acquired at a premium or slight discount, the Company believes that the contractual yield approach outlined in ASC Topic 310-20 is the more appropriate approach to apply.

FDIC loss share receivable

Because the FDIC will reimburse the Company for certain loans acquired in 2009 and 2010 should the Company experience a loss, an indemnification asset is recorded at fair value at the acquisition date. The indemnification asset is recognized at the same time as the indemnified loans, and measured on the same basis, subject to collectability or contractual limitations. The shared loss agreements on the acquisition date reflect the reimbursements expected to be received from the FDIC, using an appropriate discount rate, which reflects counterparty credit risk and other uncertainties.

The shared loss agreements continue to be measured on the same basis as the related indemnified loans, and the loss share receivable is impacted by changes in estimated cash flows associated with these loans. Deterioration in the credit quality of the acquired loans and related expected cash flows (immediately recorded as an adjustment to the allowance for credit losses) would immediately increase the loss share receivable, with the offset recorded through the consolidated statement of income. Increases in the credit quality of the acquired loans and related cash flows (reflected as an adjustment to yield and accreted into income over the remaining life of the loans) decrease the basis of the shared loss agreements, with such decrease being amortized into income over 1) the life of the loan or 2) the life of the shared loss agreements, whichever is shorter. Loss assumptions used to measure the basis of the indemnified loans are consistent with the loss assumptions used to measure the indemnification asset. Fair value accounting incorporates into the fair value of the indemnification asset an element of the time value of money, which is accreted back into income over the life of the shared loss agreements.

Upon the collection from the FDIC of an incurred loss the indemnification asset will be reduced by the amount owed by the FDIC. A corresponding claim receivable is established when a loss is incurred and recorded in other assets until cash is received from the FDIC.

For further discussion of the Company’s acquisitions and loan accounting, see Note 4 and Note 6 to the consolidated financial statements.

ALLOWANCE FOR CREDIT LOSSES

The allowance for credit losses represents management’s best estimate of probable credit losses inherent in the loan portfolios and off-balance sheet lending commitments at the balance-sheet date. The allowance for credit losses is maintained at a level the Company considers appropriate and is based on quarterly assessments and evaluations of the collectability and historical loss experience, including both industry and Company specific considerations. While management uses the best information available to establish the allowance for credit losses, future adjustments may be necessary if economic conditions differ substantially from the assumptions used in determining the allowance or, if required by regulators, based upon information available to them at the time of their examinations, or if mandated by revisions to, new interpretations of, or issuance of new accounting standards. See Note 7 for an analysis of the Company’s allowance for credit losses by portfolio and portfolio segment, and credit quality information by class. The entire amount of the allowance for credit losses is available to absorb losses on any category or lending-related commitment for non-acquired loans. The allowance related to acquired loans represents management’s best estimate of cumulative impairment as described further in “Purchase Impaired Loans (Acquired Loans)”.

The Company’s strategy for credit risk management includes a combination of conservative exposure limits, which are significantly below legal lending limits and conservative underwriting, documentation and collection standards. The strategy emphasizes geographic, industry, and customer diversification within the Company’s operating footprint, regular credit examinations, and regular management reviews of large credit exposures and loans experiencing credit quality deterioration.

The Company has not substantively changed any material aspect in its overall approach of determining the current year allowance for credit losses. There have been no material changes in criteria or estimation techniques as compared to prior periods that impacted the determination of the current allowance for credit losses.

Allowance for credit losses discussion below includes discussion specific to loans accounted for under the contractual yield method, referred to as “contractual loans”, and loans accounted for as acquired credit impaired loans.

Contractual Loans (Excluding Acquired Loans)

Contractual loans represent loans accounted for under the contractual yield method. The Company’s contractual loans include loans originated by the Company and acquired loans that are not accounted for as acquired credit impaired loans, typically referred to as legacy loans. Credit losses on contractual loans are charged and recoveries are credited to the allowance for credit losses. Provisions for loan losses are based on the Company’s review of historical industry and Company specific loss experience, and factors that management determines should be considered in estimating probable credit losses.

Loans identified as impaired are subject to individual quarterly review for potential loss. The Company considers the current value of collateral, credit quality of any guarantees, the guarantor’s liquidity and willingness to cooperate, and other factors when evaluating whether an individual loan is impaired. Other factors may include the industry and geographic location of the borrower, size and financial condition of the borrower, cash flow and leverage of the borrower, and evaluation of the borrower’s management. When individual loans are impaired, allowances are estimated based on management’s assessment of the borrower’s ability to repay the loan given the availability of collateral and other sources of cash flow, including evaluation of available legal options. Allowances for individually impaired loans are estimated based on the present value of expected future cash flows discounted at the loan’s effective interest rate, fair value of the underlying collateral or readily observable secondary market values. Collectability of principal and interest is evaluated in assessing the need for a loss accrual.

The Company also estimates reserves for collective impairment that reflect an estimated measurement of losses related to loans not subject to individual review as of the balance sheet date. Such loans are grouped in homogenous pools or segments, which are consistent with the segments and classes described above. Embedded loss rates are derived from migration analyses, which track net charge-off experience sustained on loans according to their risk grade, and may be adjusted for Company-specific and/or industry factors. Loss rates are reviewed quarterly and adjusted as management deems necessary based on changing borrower and/or collateral conditions and actual collections and charge-off experience.

Based on observations made through a qualitative review, management may apply qualitative adjustments to the quantitatively determined loss estimates at a pool and/or portfolio segment level as deemed appropriate. Primary qualitative and environmental factors that may not be directly reflected in quantitative estimates include:

• asset quality trends,

• changes in lending and risk management practices and procedures

• trends in the nature and volume of the loan portfolio, including the existence and effect of any portfolio concentrations

• changes in experience and depth of lending staff

• legal, regulatory and competitive environment

• national and regional economic trends

• data availability and applicability

Changes in these factors are considered in determining the directional consistency of changes in the allowance for credit losses. The impact of these factors on the Company’s qualitative assessment of the allowance for credit losses can change from period to period based on management’s assessment of the extent to which these factors are already reflected in historic loss rates. The uncertainty inherent in the estimation process is also considered in evaluating the allowance for credit losses.

Purchased Impaired Loans (Acquired Loans)

Purchased impaired loans represent loans acquired by the Company, which are accounted in accordance with ASC 310-30. Credit losses incurred subsequent to acquisition are charged to the allowance for credit losses. Recoveries are credited to the allowance for credit losses to the extent the losses were incurred subsequent to acquisition. Recoveries related to credit losses incurred prior to acquisition are reflected as prospective adjustments to yield, which are accreted to income over the remaining life of the associated pool of loans. Provisions for credit losses are based on the Company’s determination of the timing and amount of expected cash flows. Provisions for credit losses associated with loans covered by loss share agreements with the FDIC are partially offset by increases in the FDIC loss share receivable.

The allowance for credit losses related to loans accounted for as purchased impaired loans is based on management’s re-estimation of expected cash flows for each loan pool. An allowance for credit losses is established to the extent that the expected cash flows of a loan pool have decreased since acquisition.

OFF-BALANCE SHEET CREDIT RELATED FINANCIAL INSTRUMENTS

The Company accounts for its guarantees in accordance with the provisions of ASC Topic 460. In the ordinary course of business, the Company has entered into commitments to extend credit, including commitments under credit card arrangements, commercial letters of credit and standby letters of credit. Such financial instruments are recorded when they are funded.

DERIVATIVE FINANCIAL INSTRUMENTS

ASC Topic 815 requires that all derivatives be recognized as assets or liabilities in the balance sheet at fair value. The Company may enter into derivative contracts to manage exposure to interest rate risk or to meet the financing and/or investing needs of its customers.

In the course of its business operations, the Company is exposed to certain risks, including interest rate, liquidity, and credit risk. The Company manages its risks through the use of derivative financial instruments, primarily through management of exposure due to the receipt or payment of future cash amounts based on interest rates. The Company’s derivative financial instruments manage the differences in the timing, amount, and duration of expected cash receipts and payments.

The primary types of derivatives used by the Company include interest rate swap agreements, forward sales contracts, interest rate lock commitments, and written and purchased options.

Hedging Activities

As part of its activities to manage interest rate risk due to interest rate movements, the Company has engaged in interest rate swap transactions to manage exposure to interest rate risk through modification of the Company’s net interest sensitivity to levels deemed to be appropriate. The Company utilizes these interest rate swap agreements to convert a portion of its variable-rate debt to a fixed rate (cash flow hedge). Interest rate swaps are contracts in which a series of interest rate flows are exchanged over a prescribed period. The notional amount on which the interest payments are based is not exchanged.

Because the swap agreements used to manage interest rate risk have been designated as hedging exposure to variable cash flows of a forecasted transaction, the effective portion of the derivative’s gain or loss is initially reported as a component of other comprehensive income and subsequently reclassified into earnings when the forecasted transaction affects earnings or when the hedge is terminated. The ineffective portion of the gain or loss is reported in earnings immediately.

In applying hedge accounting for derivatives, the Company establishes a method for assessing the effectiveness of the hedging derivative and a measurement approach for determining the ineffective aspect of the hedge upon the inception of the hedge. These methods are consistent with the Company’s approach to managing risk.

Other Derivative Instruments

Interest rate swap agreements

In addition to using derivative instruments as an interest rate risk management tool, the Company also enters into derivative instruments to help its commercial customers manage their exposure to interest rate fluctuations. To mitigate the interest rate risk associated with these customer contracts, the Company enters into offsetting derivative contract positions. The Company manages its credit risk, or potential risk of default by its commercial customers, through credit limit approval and monitoring procedures.

For interest rate swap agreements that are not designated as hedging instruments, changes in the fair value of the derivatives are recognized in earnings immediately.

5

Rate lock commitments

The Company enters into commitments to originate loans intended for sale whereby the interest rate on the prospective loan is determined prior to funding (“rate lock commitments”). A rate lock is given to a borrower, subject to conditional performance obligations, for a specified period of time that typically does not exceed 60 days. Simultaneously with the issuance of the rate lock to the borrower, a rate lock is received from an investor for a best efforts or mandatory delivery of the loan. Under the terms of the best efforts delivery lock, the investor commits to purchase the loan at a specified price, provided the loan is funded and delivered prior to a specified date and provided that the credit and loan characteristics meet pre-established criteria for such loans. Rate lock commitments on mortgage loans that are intended to be sold are considered to be derivatives. Accordingly, such commitments are recorded at fair value as derivative assets or liabilities, with changes in fair value recorded in mortgage income.

Equity-indexed certificates of deposit

IBERIABANK offers its customers a certificate of deposit that provides the purchaser a guaranteed return of principal at maturity plus potential return, which allows IBERIABANK to identify a known cost of funds. The rate of return is based on the performance of a basket of publically traded stocks that represent a variety of industry segments. Because it is based on an equity index, the rate of return represents an embedded derivative that is not clearly and closely related to the host instrument and is to be accounted for separately. Accordingly, the certificate of deposit is separated into two components: a zero coupon certificate of deposit (the host instrument) and a written option purchased by the depositor (an embedded derivative). The discount on the zero coupon deposit is amortized over the life of the deposit, and the written option is carried at fair value on the Company’s consolidated balance sheet, with changes in fair value recorded through earnings. IBERIABANK offsets the risks of the written option by purchasing an option with terms that mirror the written option and that is also carried at fair value on the Company’s consolidated balance sheet.

PREMISES AND EQUIPMENT

Land is carried at cost. Buildings, furniture, fixtures, and equipment are carried at cost, less accumulated depreciation computed on a straight line basis over the estimated useful lives of 10 to 40 years for buildings and 3 to 15 years for furniture, fixtures and equipment. Capitalized leasehold improvements are amortized over the length of the initial lease agreement or their useful life, whichever is shorter.

OTHER REAL ESTATE

Other real estate includes all real estate, other than bank premises used in bank operations, owned or controlled by the Company, including real estate acquired in settlement of loans. Properties are recorded at the balance of the loan (which is the pro-rata carrying value of loans accounted for in accordance with ASC 310-30) or at estimated fair value less estimated selling costs, whichever is less, at the date acquired. Subsequent to foreclosure, management periodically performs valuations and the assets are carried at the lower of cost or fair value less estimated selling costs. Revenue and expenses from operations, gain or loss on sale and changes in the valuation allowance are included in net expenses from foreclosed assets.

For further discussion of the Company’s other real estate owned, see Note 11 to the consolidated financial statements.

GOODWILL AND OTHER INTANGIBLE ASSETS

Goodwill

Goodwill is accounted for in accordance with ASC Topic 350, and accordingly is not amortized but is evaluated at least annually for impairment. As part of its testing, the Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the Company determines the fair value of a reporting unit is less than its carrying amount using these qualitative factors, the Company compares the fair value of goodwill with its carrying amount, and then measures impairment loss by comparing the implied fair value of goodwill with the carrying amount of that goodwill.

Title Plant

The Company records its title plant assets in accordance with ASC Topic 950. Under ASC Topic 950, costs incurred to construct a title plant, including the costs incurred to obtain, organize, and summarize historical information, are capitalized until the title plant can be used to perform title searches. Purchased title plant, including a purchased undivided interest in title plant, is recorded at cost at the date of acquisition. For title plant acquired separately or as part of a company acquisition, cost is measured as the fair value of the consideration given. Capitalized costs of title plant are not depreciated or charged to income unless circumstances indicate that the carrying amount of the title plant has been impaired. Impairment identifiers include a change in legal requirements or statutory practices, identification of obsolescence, and abandonment of the title plant, among other identifiers.

Intangible assets subject to amortization

The Company’s acquired intangible assets that are subject to amortization include core deposit intangibles, amortized on a straight line or accelerated basis over a 10 year average life and a customer relationship intangible asset, amortized on an accelerated basis over a 9.5 year life.

TRANSFERS OF FINANCIAL ASSETS

Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when 1) the assets have been isolated from the Company, 2) the transferee obtains the right, free of conditions that constrain it from taking advantage of that right, to pledge or exchange the transferred assets, and 3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Should the transfer not meet these three criteria, the transaction is treated as a secured financing.

6

INCOME TAXES

The Company and all subsidiaries file a consolidated federal income tax return on a calendar year basis. The Company files income tax returns in the U.S. federal jurisdiction and various state jurisdictions through IBERIABANK, LTC and their subsidiaries. In lieu of Louisiana state income tax, IBERIABANK is subject to the Louisiana bank shares tax, which is included in noninterest expense or income tax expense in the Company’s consolidated financial statements. With few exceptions, the Company is no longer subject to U.S. federal, state or local income tax examinations for years before 2009.

Deferred income tax assets and liabilities are determined using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is determined based on the tax effects of the temporary differences between the book and tax bases of the various balance sheet assets and liabilities and gives current recognition to changes in tax rates and laws. The measurement of deferred tax assets is reduced, if necessary, by the amount of any tax benefits that, based on available evidence, are not expected to be realized.

The Company recognizes interest and penalties accrued related to unrecognized tax benefits, if applicable, in noninterest expense.

STOCK COMPENSATION PLANS

The Company issues stock options and restricted stock under various plans to directors, officers and other key employees. The Company accounts for its stock compensation plans in accordance with ASC Topics 718 and 505. Under those provisions, the Company has adopted a fair value based method of accounting for employee stock compensation plans, whereby compensation cost is measured at the grant date based on the value of the award and is recognized on a straight-line basis over the service period, which is usually the vesting period, taking into account retirement eligibility. As a result, compensation expense relating to stock options and restricted stock is reflected in net income as part of “Salaries and employee benefits” on the consolidated statements of income. The Company’s practice has been to grant options at no less than the fair market value of the stock at the grant date.

See Note 19 for additional information on the Company’s share-based compensation plans.

EARNINGS PER COMMON SHARE

Basic earnings per share represents income available to common shareholders divided by the weighted average number of common shares outstanding during the period. Diluted earnings per share reflect additional common shares that would have been outstanding if dilutive potential common shares, in the form of stock options, had been issued, as well as any adjustment to income that would result from the assumed issuance. Participating common shares issued by the Company relate to unvested outstanding restricted stock awards, the earnings allocated to which are used in determining income available to common shareholders under the two-class method.

See Note 3 for additional information on the Company’s calculation of earnings per share.

TREASURY STOCK

The purchase of the Company’s common stock is recorded at cost. At the date of retirement or subsequent reissuance, treasury stock is reduced by the cost of such stock with differences recorded in additional paid-in capital or retained earnings, as applicable.

COMPREHENSIVE INCOME

Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income. Although certain changes in assets and liabilities, such as unrealized gains and losses on available for sale securities and cash flow hedges, are reported as a separate component of the equity section of the balance sheet, such items, along with net income, are components of comprehensive income.

SEGMENTS

All of the Company’s banking operations are considered by management to be aggregated in one reportable operating segment. Because the overall banking operations comprise substantially all of the consolidated operations and none of the Company’s other subsidiaries, either individually or in the aggregate, meet quantitative materiality thresholds, no separate segment disclosures are presented in these consolidated financial statements. The Company has invested in its financial reporting infrastructure to report financial information associated with performance of lines of business within the banking operating segment. The Company anticipates reporting this information sometime in 2013.

FAIR VALUE MEASUREMENTS

The Company estimates fair value based on the assumptions market participants would use when selling an asset or transferring a liability and characterizes such measurements within the fair value hierarchy based on the inputs used to develop those assumptions and measure fair value. The hierarchy requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows:

• Level 1 – Quoted prices in active markets for identical assets or liabilities.

• Level 2 – Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

• Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs.

A description of the valuation methodologies used for instruments measured at fair value follows, as well as the classification of such instruments within the valuation hierarchy.

Securities available for sale

Securities are classified within Level 1 where quoted market prices are available in an active market. Inputs include securities that have quoted prices in active markets for identical assets. If quoted market prices are unavailable, fair value is estimated using quoted prices of securities with similar characteristics, at which point the securities would be classified within Level 2 of the hierarchy. Examples may include certain collateralized mortgage and debt obligations.

Mortgage loans held for sale

As of December 31, 2012, the Company has $267,475,000 of conforming mortgage loans held for sale. Mortgage loans originated and held for sale are carried at the lower of cost or estimated fair value. The Company obtains quotes or bids on these loans directly from purchasing financial institutions. Mortgage loans held for sale that were recorded at estimated fair value are included in the table in Note 22.

Impaired loans

Loans are measured for impairment using the methods permitted by ASC Topic 310. Fair value measurements are used in determining impairment using either the loan’s obtainable market price, if available (Level 1) or the fair value of the collateral if the loan is collateral dependent (Level 2). Measuring the impairment of loans using the present value of expected future cash flows, discounted at the loan’s effective interest rate, is not considered a fair value measurement. Fair value of the collateral is determined by appraisals or independent valuation.

Other real estate owned

Fair values of OREO at December 31, 2012 are determined by sales agreement or appraisal, and costs to sell are based on estimation per the terms and conditions of the sales agreement or amounts commonly used in real estate transactions. Inputs include appraisal values on the properties or recent sales activity for similar assets in the property’s market, and thus OREO measured at fair value would be classified within Level 2 of the hierarchy. The Company included property write-downs of $6,409,000, $7,250,000, and $2,943,000 in earnings for the years ended December 31, 2012, 2011, and 2010, respectively.

Derivative financial instruments

The Company utilizes interest rate swap agreements to convert a portion of its variable-rate debt to a fixed rate (cash flow hedge). The Company also enters into commitments to originate loans whereby the interest rate on the prospective loan is determined prior to funding (“rate lock commitments”). Rate lock commitments on mortgage loans that are intended to be sold are considered to be derivatives. The Company offers its customers a certificate of deposit that provides the purchaser a guaranteed return of principal at maturity plus potential return, which allows the Company to identify a known cost of funds. The rate of return is based on an equity index, and as such represents an embedded derivative. Fair value of interest rate swaps, interest rate lock commitments, and equity-linked written and purchased options are estimated using prices of financial instruments with similar characteristics, and thus are classified within Level 2 of the fair value hierarchy.

NOTE 2 – RECENT ACCOUNTING PRONOUNCEMENTS

ASU No. 2011-04

In 2012, the Company adopted the provisions of ASU No. 2011-04, Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in US GAAP and IFRSs, which changes the wording used to describe many of the requirements in U.S. GAAP for measuring fair value and for disclosing information about fair value measurements. The amendments clarify that the Company should disclose quantitative information about the unobservable inputs used in a fair value measurement that is categorized within Level 3 of the fair value hierarchy. Requiring quantitative information does not change the objective of the requirement but increases the comparability of disclosures between disclosures under U.S. GAAP and IFRSs.

The disclosures required by this ASU are incorporated in Notes 22 and 23 in these consolidated financial statements.

7

ASU No. 2011-05

In 2012, the Company adopted the provisions of Accounting Standards Update (“ASU”) No. 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income, which increases the prominence of items reported in other comprehensive income and eliminates the option to report other comprehensive income as part of the statement of shareholders’ equity. The ASU requires that all nonowner changes in shareholders’ equity be presented in either a single continuous statement of comprehensive income or in two separate but consecutive statements. The adoption of this ASU did not change the items that are reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income. The adoption also did not change the option to present components of other comprehensive income either net of related tax effects or before related tax effects. The tax effect for each component must be disclosed in the notes to the consolidated financial statements or presented in the statement in which other comprehensive income is presented. The amendments also do not affect how earnings per share is calculated or presented.

The Company has chosen to present the nonowner changes in shareholders’ equity in a single continuous statement of comprehensive income in its consolidated financial statements. The adoption of the ASU in the current year affects the format and presentation of its consolidated financial statements but does not represent a departure from currently adopted accounting principles and thus the adoption did not have an effect on the Company’s operating results, financial position, or liquidity. The financial statements for the comparative prior period have been revised to conform to current period presentation.

ASU No. 2012-02

In 2012, the Company adopted the provisions of ASU No. 2012-02, Intangibles – Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment, which provides the Company with the option to make a qualitative assessment about the likelihood that an indefinite-lived intangible asset is impaired to determine whether it should perform a quantitative impairment test. The ASU also enhances the consistency of impairment testing guidance among long-lived asset categories by permitting the Company to assess qualitative factors to determine whether it is necessary to calculate the asset’s fair value when testing an indefinite-lived intangible asset for impairment, which is equivalent to the impairment testing requirements for other long-lived assets. In accordance with the amendments in this Update, an entity will have an option not to calculate annually the fair value of an indefinite-lived intangible asset if the entity determines that it is not more likely than not that the asset is impaired. Permitting the Company to assess qualitative factors when testing indefinite-lived intangible assets for impairment results in guidance that is similar to the goodwill impairment testing guidance in ASU No. 2011-08. The adoption of the ASU in the current year does not represent a departure from currently adopted accounting principles and thus the adoption did not have an effect on the Company’s operating results, financial position, or liquidity.

ASU No. 2012-06

In 2012, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2012-06, Business Combinations (Topic 805): Subsequent Accounting for an Indemnification Asset Recognized at the Acquisition Date as a Result of a Government-Assisted Acquisition of a Financial Institution, which clarifies the applicable guidance for subsequently measuring an indemnification asset recognized in a government-assisted acquisition of a financial institution that includes a loss-sharing agreement. The ASU addresses the diversity in practice in the interpretation of the terms “on the same basis” and “contractual limitations” used in accounting guidance. Accounting principles require that an indemnification asset recognized at the acquisition date as a result of a government-assisted acquisition of a financial institution involving an indemnification agreement shall be subsequently measured on the same basis as the indemnified item. The provisions of ASU No. 2012-06 clarify that, upon subsequent remeasurement of an indemnification asset, the effect of the change in expected cash flows of the indemnification agreement shall be amortized. Any amortization of changes in value is limited to the lesser of the contractual term of the indemnification agreement and the remaining life of the indemnified assets. The ASU does not affect the guidance relating to the recognition or initial measurement of an indemnification asset.

The provisions in this ASU are effective beginning with the Company’s first quarter of 2013, with early adoption permitted. Because the estimated lives of indemnification assets are an accounting estimate, the impact of the adoption of ASU No. 2012-06 will be prospective, meaning that changes in the estimated life will impact the future earnings of the Company. The rate of amortization of the indemnification assets by the Company has been estimated over the life of the underlying covered loans using a static spread to the rate earned on the covered loans. The adoption of ASU No. 2012-06 will change how the Company amortizes its indemnification assets. The Company currently expects to have higher future amortization in the near term and does not expect a material impact on its financial position and liquidity resulting from the adoption of this ASU.

ASU No. 2013-02

In February 2013, the FASB issued ASU No. 2013-06, Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, which requires the Company to report the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income on the Company’s consolidated statement of comprehensive income if the amount being reclassified is required under US GAAP to be reclassified in its entirety to net income. The ASU does not change the current requirements for reporting net income or other comprehensive income in the consolidated financial statements of the Company, but does require the Company to provide information about the amounts reclassified out of accumulated other comprehensive income by component.

The provisions in the ASU are effective prospectively beginning with the Company’s first quarter of 2013, with early adoption permitted. The adoption of the ASU affects the format and presentation of its consolidated financial statements and the footnotes to the consolidated financial statements, but does not represent a departure from currently adopted accounting principles and thus the adoption will not have an effect on the Company’s operating results, financial position, or liquidity.

NOTE 3 – EARNINGS PER SHARE

Share-based payment awards that entitle holders to receive non-forfeitable dividends before vesting are considered participating securities and thus included in the calculation of basic earnings per share. These awards are included in the calculation of basic earnings per share under the two-class method. The two-class method allocates earnings for the period between common shareholders and other security holders. The participating awards receiving dividends will be allocated the same amount of income as if they were outstanding shares.

The following table presents the calculation of basic and diluted earnings per share for the years ended December 31, 2012, 2011, and 2010.

	For the Years Ended December 31,

(1) Weighted average basic shares outstanding include 552,609, 484,361, and 498,692 shares of unvested restricted stock for the years ended December 31, 2012, 2011, and 2010, respectively.

Additional information on the Company’s basic earnings per common share is shown in the following table.

	For the Years Ended December 31,
(Dollars in thousands, except per share data)	2012		2011		2010
Distributed earnings to common shareholders	$	39,349	$	38,681	$	35,772

Undistributed earnings per unvested restricted stock share		1.24		0.54		0.50
Total earnings per unvested restricted stock share - Basic	$	2.61	$	2.04	$	1.97

For the years ended December 31, 2012, 2011, and 2010, the calculations for basic shares outstanding exclude: (1) the weighted average shares owned by the Recognition and Retention Plan (“RRP”) of 612,097, 571,262 and 560,767, respectively, and (2) the weighted average shares in treasury stock of 1,964,825, 1,300,222, and 1,256,418, respectively.

9

The effect from the assumed exercise of 752,188, 542,716, and 477,665 stock options was not included in the computation of diluted earnings per share for years ended December 31, 2012, 2011, and 2010, respectively, because such amounts would have had an antidilutive effect on earnings per share.

NOTE 4 – ACQUISITION AND DISPOSITION ACTIVITY

Acquisition of Florida Gulf Bancorp, Inc.

On July 31, 2012, the Company acquired Florida Gulf Bancorp, Inc. (“Florida Gulf”), the holding company of Florida Gulf Bank, headquartered in Fort Myers, Florida with 8 branches in the Fort Myers-Cape Coral, FL market. The Company acquired Florida Gulf in order to further expand its banking operations in the Fort Myers Metropolitan area. Under terms of the agreement, for each share of Florida Gulf stock outstanding, Florida Gulf shareholders received shares of the Company’s common stock equal to $23.00 and a cash payment for any fractional share. In addition, the agreement provides for potential additional cash consideration based on the resolution of certain identified loans over a three-year period after the acquisition. The Company acquired all of the outstanding common stock of the former Florida Gulf shareholders for total consideration of $45,339,000, which included the fair value of options granted and non-equity consideration paid, which resulted in goodwill of $32,420,000, as shown in the following table:

(Dollars in thousands)	Number of Shares		Amount
Equity Consideration
Common Stock issued		754,334	$	37,210
Options issued		32,863		651
Total Equity Consideration				37,861
Non-Equity Consideration
Change in Control Payments				1,342
Cash				4,625
Contingent Consideration				1,511
Total Non-Equity Consideration				7,478
Total Consideration Paid				45,339
Fair Value of Net Assets Assumed including Identifiable Intangible Assets				(12,919	)
Goodwill			$	32,420

The acquisition was accounted for under the purchase method of accounting in accordance with ASC Topic 805. Both the purchased assets and liabilities assumed were recorded at their respective acquisition date fair values. Identifiable intangible assets, including core deposit intangible assets, if any, were recorded at fair value. Because the consideration paid was greater than the net fair value of the acquired assets and liabilities, the Company recorded goodwill as part of the acquisition. The goodwill recognized was the result of the combined Companies’ expanded presence in the Fort Myers, Florida Metropolitan Statistical Area (“MSA”) through the addition of eight branches and an experienced in-market team that enhances the Company’s ability to compete in that market. Additionally, goodwill was also created by the expected cost savings that will be recognized in future periods through the elimination of redundant operations. Goodwill created in the acquisition in not deductible for income tax purposes.

In accordance with ASC Topic 805, estimated fair values are subject to change up to one year after the acquisition date. This allows for adjustments to the initial purchase entries if additional information relative to closing date fair values becomes available. Material adjustments to acquisition date estimated fair values would be recorded in the period in which the acquisition occurred, and as a result, previously reported results are subject to change. Information regarding the Company’s loan discount and related deferred tax asset, as well as income taxes payable and the related deferred tax balances, recorded in the acquisition may be adjusted as the Company refines its estimates of the current and deferred tax balances acquired, as well as the fair values of loans acquired and the deferred tax assets created from the acquisition. Determining the fair value of assets and liabilities, particularly illiquid assets and liabilities, is a complicated process involving significant judgment regarding estimates and assumptions used to calculate estimated fair value. The Company may incur losses on the acquired loans that are materially different from losses the Company originally projected. Fair value adjustments based on updated estimates could materially affect the goodwill recorded on the acquisition.

10

The acquired assets and liabilities, as well as the adjustments to record the assets and liabilities at their estimated fair values, are presented in the following table.

(Dollars in thousands)	As Acquired		Preliminary  Fair Value Adjustments			As recorded  by IBERIABANK

Explanation of Certain Fair Value Adjustments

(1) The adjustment represents the write down of the book value of Florida Gulf’s investments to their estimated fair value based on fair values on the date of acquisition.

(2) The adjustment represents the write down of the book value of Florida Gulf’s loans to their estimated fair value based on current interest rates and expected cash flows which includes estimates of expected credit losses inherent in the portfolio.

(3) The adjustment represents the write down of the book value of Florida Gulf’s OREO properties to their estimated fair value at the acquisition date based on their appraised value, as adjusted for costs to sell.

(4) The adjustment represents the deferred tax asset recognized on the fair value adjustments of Florida Gulf’s acquired assets and assumed liabilities.

(5) The adjustment represents the write down of the book value of Florida Gulf’s property, equipment, and other assets to their estimated fair value at the acquisition date based on their appraised value.

(6) The adjustment is necessary because the weighted average interest rate of Florida Gulf’s CDs exceeded the cost of similar funding at the time of acquisition. The fair value adjustment will be amortized to reduce interest expense over the life of the portfolio, which is estimated at 60 months.

(7) The adjustment is necessary because the interest rate of Florida Gulf’s fixed rate borrowings exceeded current interest rates on similar borrowings.

The Company’s consolidated financial statements as of and for the year ended December 31, 2012 include the operating results of the acquired assets and assumed liabilities for the 153 days subsequent to the July 31, 2012 acquisition date. Due to the system conversion of the acquired entity in August 2012 and subsequent integration of the operating activities of the acquired branches into existing Company markets, historical reporting for the former Florida Gulf branches is impracticable and thus disclosure of the revenue from the assets acquired and income before income taxes is impracticable for the 153-day period.

Acquisitions of OMNI BANCSHARES, Inc., Cameron Bancshares, Inc., and certain assets of Florida Trust Company

On May 31, 2011, the Company acquired OMNI BANCSHARES, Inc. (“OMNI”), the holding company of OMNI BANK, headquartered in Metairie, Louisiana with 14 offices in the New Orleans and Baton Rouge, LA markets. The Company acquired all of the outstanding common stock of the former OMNI shareholders for total consideration of $46,407,000, which resulted in goodwill of $63,756,000.

Also on May 31, 2011, the Company acquired Cameron Bancshares, Inc. (“Cameron”), the holding company of Cameron State Bank, headquartered in Lake Charles, Louisiana, with 22 offices and 48 ATMs in the Lake Charles region, in order to expand its banking operations into the Lake Charles, Louisiana area. The Company acquired all of the outstanding common stock of the former Cameron shareholders for total consideration of $143,241,000, which resulted in goodwill of $71,417,000.

On June 14, 2011, the Company purchased certain assets of the Florida Trust Company, a wholly-owned subsidiary of the Bank of Florida Corporation. Florida Trust Company operated offices in Naples and Ft. Lauderdale, Florida. Upon acquisition, the Florida Trust Company became part of the trust and asset management division of IBERIABANK. Under terms of the agreement, IBERIABANK paid the Bank of Florida Corporation $700,000 and a contingent payment of $670,000 for the acquisition of substantially all of the assets of Florida Trust Company. The acquisition resulted in additional intangible assets of $1,400,000 included in the Company’s consolidated balance sheet as of December 31, 2011, of which $52,000 was goodwill.

The acquisitions were accounted for under the purchase method of accounting in accordance with ASC Topic 805. Both the purchased assets and liabilities assumed were recorded at their respective acquisition date fair values. Identifiable intangible assets, including core deposit intangible assets, were recorded at fair value. Because the consideration paid was greater than the net fair value of the acquired assets and liabilities, the Company recorded goodwill as part of the acquisitions.

The acquired assets and liabilities are presented in the following table at fair value at each entity’s respective acquisition date. The table also includes intangible assets other than goodwill created in the acquisition, namely, core deposit intangible assets and a customer relationship intangible asset.

Total	$	1,620,558	$	1,651,492

Securities with carrying values of $1,712,860,000 and $1,698,943,000 were pledged to secure public deposits and other borrowings at December 31, 2012 and December 31, 2011, respectively.

Management evaluates securities for other-than-temporary impairment at least quarterly, and more frequently when economic or market concerns warrant such evaluation. Consideration is given to 1) the length of time and the extent to which the estimated fair value has been less than amortized cost, 2) the financial condition and near-term prospects of the issuer, and 3) the intent and ability of the Company to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in estimated fair value above amortized cost. In analyzing an issuer’s financial condition, management considers whether the securities are issued by the federal government or its agencies and whether downgrades by bond rating agencies have occurred, as well as review of issuer financial statements and industry analysts’ reports.

Information pertaining to securities with gross unrealized losses at December 31, 2012 and 2011 aggregated by investment category and length of time that individual securities have been in a continuous loss position, follows:

The Company assessed the nature of the losses in its portfolio as of December 31, 2012 and 2011 to determine if there are losses that are deemed other-than-temporary. In its analysis of these securities, management considered numerous factors to determine whether there were instances where the amortized cost basis of the debt securities would not be fully recoverable, including, but not limited to:

• the length of time and extent to which the estimated fair value of the securities was less than their amortized cost,

14

• whether adverse conditions were present in the operations, geographic area, or industry of the issuer,

• the payment structure of the security, including scheduled interest and principal payments, including the issuer’s failures to make scheduled payments, if any, and the likelihood of failure to make scheduled payments in the future,

• changes to the rating of the security by a rating agency, and

• subsequent recoveries or additional declines in fair value after the balance sheet date.

Management believes it has considered these factors, as well as all relevant information available, when determining the expected future cash flows of the securities in question. Except for the bond discussed below, in each instance, management has determined the cost basis of the securities would be fully recoverable. Management also has the intent and ability to hold debt securities until their maturity or anticipated recovery if the security is classified as available for sale. In addition, management does not believe the Company will be required to sell debt securities before the anticipated recovery of the amortized cost basis of the security.

At December 31, 2012, 49 debt securities had unrealized losses of 0.85% of the securities’ amortized cost basis and 0.12% of the Company’s total amortized cost basis. The unrealized losses for each of the 49 securities relate to market interest rate changes. Three of the 49 securities have been in a continuous loss position for over twelve months at December 31, 2012. These three securities had an aggregate amortized cost basis and unrealized loss of $5,200,000 and $187,000, respectively. Two of the three securities were issued by either the Federal National Mortgage Association (Fannie Mae), Federal Home Loan Mortgage Corporation (Freddie Mac), or the Government National Mortgage Association (Ginnie Mae). The Fannie Mae, Freddie Mac, and Ginnie Mae securities are rated AA+ by S&P and Aaa by Moodys. One of the securities in a continuous unrealized loss position for over twelve months was issued by a political subdivision and discussed in further detail below.

At December 31, 2011, 50 debt securities had unrealized losses of 0.5% of the securities’ amortized cost basis and 0.1% of the Company’s total amortized cost basis. The unrealized losses for each of the 50 securities relate to market interest rate changes. 12 of the 50 securities had been in a continuous loss position for over twelve months at December 31, 2011. These 12 securities had an aggregate amortized cost basis and unrealized loss of $24,453,000 and $391,000 respectively. The 12 securities were issued by either Federal National Mortgage Association (Fannie Mae), Federal Home Loan Mortgage Corporation (Freddie Mac) or by state and political subdivisions. The Fannie Mae and Freddie Mac securities were rated AA+ by S&P and Aaa by Moodys.

During 2011, management assessed the operating environment of a bond issuer as adverse and thus concluded that the Company had one unrated revenue municipal bond that warranted an other-than-temporary impairment charge during the year ended December 31, 2011. The specific impairment was related to the loss of the contracted revenue source required for bond repayment. The Company determined the impairment charge using observable market data for similar assets, including third party valuation of the security, as well as information from unobservable inputs, including its best estimate of the recoverability of the amortized cost of the security as outlined above. Changes to the unobservable inputs used by the Company would have resulted in a higher or lower impairment charge, but the unobservable inputs were not highly sensitive and would not result in a material difference in the impairment charge recorded for the year ended December 31, 2011. The impairment recorded in 2011 brought the total impairment to 50% of the par value of the bond and provided a fair value of the bonds that was consistent with current market pricing. Because adverse conditions were noted in the operations of the bond issuer, the Company recorded the other-than-temporary impairment. During the year ended December 31, 2012, the Company continued to analyze the operating environment of the bond as it did in 2011 and noted no further deterioration in the operating environment of the bond issuer.

The following table reflects activity during the years ended December 31, 2012, 2011, and 2010 related to credit losses on the other-than-temporarily impaired investment security where a portion of the unrealized loss was recognized in other comprehensive income.

As a result of the Company’s analysis, no other declines in the estimated fair value of the Company’s investment securities were deemed to be other-than-temporary at December 31, 2012 or December 31, 2011 except where noted above.

The amortized cost and estimated fair value by maturity of investment securities at December 31, 2012 are shown in the following table. Securities are classified according to their contractual maturities without consideration of principal amortization, potential prepayments or call options. Accordingly, actual maturities may differ from contractual maturities.

In 2009, the Company acquired substantially all of the assets and liabilities of CapitalSouth Bank (“CSB”), and certain assets and assumed certain deposit and other liabilities of Orion Bank (“Orion”) and Century Bank (“Century”). In 2010, the Company acquired certain assets and assumed certain deposit and other liabilities of Sterling Bank. The loans and foreclosed real estate that were acquired in these transactions are covered by loss share agreements between the FDIC and IBERIABANK, which afford IBERIABANK significant loss protection. Under the loss share agreements, the FDIC will cover 80% of covered loan and foreclosed real estate losses up to certain thresholds for all four acquisitions, 80% of losses that exceed the thresholds for Sterling Bank, and 95% of losses that exceed those thresholds for CSB, Orion, and Century only.

16

Because of the loss protection provided by the FDIC, the risks of the CSB, Orion, Century, and Sterling loans and foreclosed real estate are significantly different from those assets not covered under the loss share agreement. Accordingly, the Company presents loans subject to the loss share agreements as “covered loans” in the information below and loans that are not subject to the loss share agreement as “non-covered loans.”

Deferred loan origination fees were $14,040,000 and $9,422,000 and deferred loan expenses were $5,270,000 and $4,828,000 at December 31, 2012 and 2011, respectively. In addition to loans issued in the normal course of business, the Company considers overdrafts on customer deposit accounts to be loans and reclassifies these overdrafts as loans in its consolidated balance sheets. At December 31, 2012 and 2011, overdrafts of $3,231,000 and $1,646,000, respectively, have been reclassified to loans receivable.

Loans with carrying values of $1,504,512,000 and $1,112,214,000 were pledged to secure public deposits and other borrowings at December 31, 2012 and December 31, 2011, respectively.

The following tables provide an analysis of the aging of non-covered loans as of December 31, 2012 and 2011. Because of the difference in the accounting for acquired loans, the tables below further segregate the Company’s non-covered loans receivable between loans acquired from Florida Gulf in 2012, as well as those acquired in 2011, and loans originated by the Company. For purposes of the following tables, subprime mortgage loans are defined as the Company’s loans that have FICO scores that are less than 620 at the time of origination or were purchased outside of a business combination.

The Company has corrected its disclosure of historical covered loan balances by portfolio type for December 31, 2011 for the impact of an error in the allocation of loan discounts in its covered loan portfolio. The correction had no effect on the balance of total covered loans, total loans, total assets, or net income for the periods presented. The error was identified in 2012 through the operation of the Company’s internal controls over financial reporting as it related to the Company’s loan accounting. Using accounting guidance provided in ASC Topic 250, the Company assessed these items and determined the error, although immaterial to the consolidated financial statements for the year ended December 31, 2012, and immaterial to the overall financial statement presentation at December 31, 2011, would affect the comparability of the disclosures provided in these consolidated financial statements. As a result, the information included in these footnotes includes the effect this correction has on the previously reported disclosures for the December 31, 2011 period.

The following table presents the effect of this correction for the December 31, 2011 period.

The Company does not anticipate owing any consideration previously received under indemnification agreements to the FDIC under the “clawback” provisions of these agreements. Of the three agreements with the FDIC that contain clawback provisions, cumulative losses to date under two of these agreements have exceeded the calculated loss amounts which would result in clawback if not incurred. The sum of the historical and remaining projected losses under the remaining agreement is in excess of the clawback amount stated in that agreement.

ASC 310-30 loans

The Company acquired loans (both covered and non-covered) through previous acquisitions which are subject to ASC Topic 310-30.

Troubled Debt Restructurings

Information about the Company’s TDRs at December 31, 2012 and 2011 is presented in the following tables. The Company excludes as TDRs modifications of loans that are accounted for within a pool under Subtopic 310-30, which include the covered loans above, as well as the loans acquired in the OMNI and Cameron acquisitions completed during 2011 and those acquired from Florida Gulf in 2012. Accordingly, such modifications do not result in the removal of those loans from the pool, even if the modification of those loans would otherwise be considered a TDR. As a result, all covered loans and loans acquired from OMNI, Cameron, and Florida Gulf that would otherwise meet the criteria for classification as a troubled debt restructuring are excluded from the tables below.

Credit Quality

The Company’s investment in non-covered loans by credit quality indicator as of December 31, 2012 and 2011 is presented in the following tables. Because of the difference in the accounting for acquired loans, the tables below further segregate the Company’s non-covered loans receivable between loans acquired and loans that were not acquired. Loan discounts in the table below represent the adjustment of non-covered acquired loans to fair value at the time of acquisition, as adjusted for income accretion and changes in cash flow estimates in subsequent periods. Asset risk classifications for commercial loans reflect the classification as of December 31, 2012 and 2011.

As of December 31, 2012 and 2011, the Company was not committed to lend additional funds to any customer whose loan was classified as impaired or as a troubled debt restructuring.

NOTE 8 – TRANSFERS AND SERVICING OF FINANCIAL ASSETS (INCLUDING MORTGAGE BANKING ACTIVITIES)

Commercial Banking Activity

Loans serviced for others, consisting primarily of commercial loan participations sold, are not included in the accompanying consolidated balance sheets. The unpaid principal balances of loans serviced for others were $257,883,000 and $198,860,000 at December 31, 2012 and 2011, respectively. Custodial escrow balances maintained in connection with the foregoing portfolio of loans serviced for others, and included in demand deposits, were immaterial at December 31, 2012 and 2011.

Mortgage Banking Activity

The Company through its subsidiary, IMC, originates mortgage loans for sale into the secondary market. The loans originated primarily consist of residential first mortgages that conform to standards established by the GSEs, but can also consist of junior lien loans secured by residential property. These sales are primarily to private companies that are unaffiliated with the GSEs on a servicing released basis. The following table details the mortgage banking activity as of and for the years ended December 31:

NOTE 10 – GOODWILL AND OTHER ACQUIRED INTANGIBLE ASSETS

Goodwill

Changes to the carrying amount of goodwill for the years ended December 31, 2012 and 2011 are provided in the following table.

(Dollars in thousands)	Amount
Balance, December 31, 2010	$	234,228
Goodwill acquired during the year		135,583
Balance, December 31, 2011		369,811
Goodwill acquired during the period		32,420
Goodwill adjustment to correct an immaterial error		(359	)
Balance, December 31, 2012	$	401,872

The goodwill acquired during the year ended December 31, 2011 was a result of the OMNI, Cameron, and Florida Trust Company acquisitions, and the goodwill acquired during the year ended December 31, 2012 was a result of the Florida Gulf acquisition discussed further in Note 4.

The goodwill adjustment in 2012 is a result of the Company’s revised goodwill recorded on its OMNI and Cameron acquisitions. The Company has recorded the adjustment to account for the impact of an immaterial error in accounting for its OMNI and Cameron acquisitions that resulted in a decrease in goodwill of $359,000. The Company revised its valuation of acquired deferred tax assets and property during the first quarter of 2012 as a result of information that existed at the acquisition date but was not available during the prior period. The error was identified in 2012 through the operation of the Company’s internal controls over financial reporting as it related to the Company’s acquisition accounting.

The Company performed the required annual impairment test of goodwill as of October 1, 2012. The Company’s annual impairment test did not indicate impairment at any of the Company’s reporting units as of the testing date, and subsequent to that date, management is not aware of any events or changes in circumstances since the impairment test that would indicate that goodwill might be impaired.

Prior to 2010, the Company recognized goodwill impairment of $9,681,000 at the Company’s LTC subsidiary based on a decrease in operating revenue and income, which resulted in the conclusion that the fair value of LTC may have been reduced below its carrying amount.

Title plant

The Company had title plant assets totaling $6,722,000 at December 31, 2012 and 2011, respectively. No events or changes in circumstances occurred during 2012 or 2011 to suggest the carrying value of the title plant was not recoverable.

The Company does not anticipate additional assets will be required to be posted as collateral, nor does it believe additional assets would be required to settle its derivative instruments immediately if contingent features were triggered at December 31, 2012. As permitted by generally-accepted accounting principles, the Company does not offset fair value amounts recognized for the right to reclaim cash collateral or the obligation to return cash collateral against recognized fair value amounts of derivatives executed with the same counterparty under a master netting agreement.

During the years ended December 31, 2012 and 2011, the Company has not reclassified into earnings any gain or loss as a result of the discontinuance of cash flow hedges because it was probable the original forecasted transaction would not occur by the end of the originally specified term.

At December 31, 2012, the fair value of derivatives that will mature within the next twelve months is $788,000. The Company does not expect to reclassify any amount from accumulated other comprehensive income into interest income over the next twelve months for derivatives that will be settled.

Treasury share repurchases

Share repurchases may be made from time to time, on the open market or in privately negotiated transactions. Such repurchases are authorized by the Board of Directors through a share repurchase program and are executed at the discretion of the management of the Company. The approved share repurchase program does not obligate the Company to repurchase any dollar amount or number of shares, and the program may be extended, modified, suspended, or discontinued at any time. Stock repurchases generally are affected through open market purchases, and may be made through unsolicited negotiated transactions. The timing of these repurchases will depend on market conditions and other requirements.

In October 2011, the Board of Directors authorized the repurchase of up to 900,000 shares of common stock. The following table details these purchases during 2012 and is based on the settlement date of the transactions. The average price paid per share includes commissions paid. No shares were repurchased during the months not presented in the table.

NOTE 18 – CAPITAL REQUIREMENTS AND OTHER REGULATORY MATTERS

The Company and IBERIABANK are subject to various regulatory capital requirements administered by the federal and state banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and IBERIABANK must meet specific capital guidelines that involve quantitative measures of their assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Prompt corrective action provisions are not applicable to bank holding companies.

Quantitative measures established by regulation to ensure capital adequacy require the Company and IBERIABANK to maintain minimum amounts and ratios of total and Tier 1 capital to risk-weighted assets and of Tier 1 capital to average assets. Management believes, as of December 31, 2012 and 2011, that the Company and IBERIABANK met all capital adequacy requirements to which they are subject.

47

As of December 31, 2012, the most recent notification from the Federal Deposit Insurance Corporation categorized IBERIABANK as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized, an institution must maintain minimum total risk-based, Tier 1 risk-based and Tier 1 leverage ratios as set forth in the following table. There are no conditions or events since the notification that management believes have changed either entity’s category. The Company’s and IBERIABANK’s actual capital amounts and ratios as of December 31, 2012 and 2011 are presented in the following table.

In June 2012, the Board of Governors of the Federal Reserve System (the “Federal Reserve”) approved three related notices of proposed rulemaking (the “NPRs”) relating to implementation of minimum capital requirements and a capital conservation buffer reflecting requirements of the Dodd-Frank Wall Street Reform and Consumer Protection Act (“Dodd-Frank Act”) and the Basel III international capital standards. The three NPRs are expected to be published jointly by the Federal Reserve, the FDIC, and the Office of the Comptroller of Currency after each agency has completed its approval process. If approved as proposed, the NPRs would be effective over a phased-in period from 2013 to 2019. The Company is in the process of evaluating the impact of the proposed rules on the Company and IBERIABANK.

NOTE 19 – SHARE-BASED COMPENSATION

The Company has various types of share-based compensation plans. These plans are administered by the Compensation Committee of the Board of Directors, which selects persons eligible to receive awards and determines the number of shares and/or options subject to each award, the terms, conditions and other provisions of the awards. During the years ended December 31, 2012, 2011, and 2010, the Company did not have any equity awards that were settled in cash.

Stock option plans

The Company issues stock options under various plans to directors, officers and other key employees. The option exercise price cannot be less than the fair value of the underlying common stock as of the date of the option grant and the maximum option term cannot exceed ten years. The stock options granted were issued with vesting periods ranging from one-and-a half to seven years. At December 31, 2012, future option or restricted stock awards of 688,943 shares could be made under approved incentive compensation plans.

The following table represents the compensation expense that is included in salaries and employee benefits expense and related income tax benefits in the accompanying consolidated statements of comprehensive income related to stock options for the years indicated below.

(Dollars in thousands, except per share data)	2012		2011		2010
Compensation expense related to stock options	$	1,873	$	1,343	$	1,301
Income tax benefit related to stock options		656		470		455
Impact on basic earnings per share		0.04		0.03		0.03
Impact on diluted earnings per share		0.04		0.03		0.03

The Company reported $1,221,000, $1,454,000 and $637,000 of excess tax benefits as financing cash inflows during the years ended December 31, 2012, 2011, and 2010, respectively, related to the exercise and vesting of stock options. Net cash proceeds from the exercise of stock options were $2,813,000, $6,807,000 and $1,631,000 for the years ended December 31, 2012, 2011, and 2010, respectively.

The Company uses the Black-Scholes option pricing model to estimate the fair value of share-based awards. The following weighted-average assumptions were used for option awards granted during the years ended December 31^st of the periods indicated:

	2012			2011			2010
Expected dividends		2.7	%		2.4	%		2.3	%
Expected volatility		40.1	%		35.5	%		39.3	%
Risk-free interest rate		0.8	%		1.5	%		2.3	%
Expected term (in years)		5.0			4.0			5.0
Weighted-average grant-date fair value	$	14.50		$	12.83		$	18.11

The assumptions above are based on multiple factors, including historical stock option exercise patterns and post-vesting employment termination behaviors, expected future exercise patterns and the expected volatility of the Company’s stock price.

At December 31, 2012, there was $5,174,000 of unrecognized compensation cost related to stock options which is expected to be recognized over a weighted-average period of 4.7 years.

At December 31, 2012, the aggregate intrinsic value of shares underlying outstanding stock options and underlying exercisable stock options was $2,647,000 and $2,600,000. Total intrinsic value of options exercised was $1,765,000, $6,783,000 and $2,314,000 for the years ended December 31, 2012, 2011, and 2010, respectively.

Restricted stock plans

The Company issues restricted stock under various plans for certain officers and directors. A supplemental stock benefit plan adopted in 1999 and the 2001, 2005, 2008, and 2010 Incentive Plans allow grants of restricted stock. The plans allow for the issuance of restricted stock awards that may not be sold or otherwise transferred until certain restrictions have lapsed. The holders of the restricted stock receive dividends and have the right to vote the shares. The fair value of the restricted stock shares awarded under these plans is recorded as unearned share-based compensation, a contra-equity account. The unearned compensation related to these awards is amortized to compensation expense over the vesting period (generally three to seven years). The total share-based compensation expense for these awards is determined based on the market price of the Company’s common stock at the date of grant applied to the total number of shares granted and is amortized over the vesting period. As of December 31, 2012, unearned share-based compensation associated with these awards totaled $22,421,000.

Phantom stock awards

As part of the 2008 Incentive Compensation Plan and 2009 Phantom Stock Plan, the Company issues phantom stock awards to certain key officers and employees. The award is subject to a vesting period of five to seven years and is paid out in cash upon vesting. The amount paid per vesting period is calculated as the number of vested “share equivalents” multiplied by the closing market price of a share of the Company’s common stock on the vesting date. Share equivalents are calculated on the date of grant as the total award’s dollar value divided by the closing market price of a share of the Company’s common stock on the grant date. Award recipients are also entitled to a “dividend equivalent” on each unvested share equivalent held by the award recipient. A dividend equivalent is a dollar amount equal to the cash dividends that the participant would have been entitled to receive if the participant’s share equivalents were issued in shares of common stock. Dividend equivalents will be deemed to be reinvested as share equivalents that will vest and be paid out on the same date as the underlying share equivalents on which the dividend equivalents were paid. The number of share equivalents acquired with a dividend equivalent is determined by dividing the aggregate of dividend equivalents paid on the unvested share equivalents by the closing price of a share of the Company’s common stock on the dividend payment date.

The following table represents phantom stock award activity during the periods indicated. During the years ended December 31, 2012, 2011, and 2010, the Company recorded $2,185,000, $1,368,000 and $381,000, respectively, in compensation expense based on the number of share equivalents vested at the end of the period and the current market price of the Company’s stock.

	Number of share equivalents			Dividend equivalents			Total share equivalents			Value of  share equivalents(1)
Balance, December 31, 2009		67,361			1,886			69,247			3,726,000

Balance, December 31, 2012		318,729			16,035			334,764		$	16,444,000

(1) Except for vested share payments, which are based on the cash paid at the time of vesting, the value of share equivalents is calculated based on the market price of the Company’s stock at the end of the respective periods. The market price of the Company’s stock was $49.12, $49.30, and $59.13 on December 31, 2012, 2011, and 2010, respectively.

401(k) profit sharing plan

The Company has a 401(k) Profit Sharing Plan covering substantially all of its employees. Annual employer contributions to the plan are set by the Board of Directors. The Company made contributions of $1,299,000, $1,177,000, and $739,000 for the years ended December 31, 2012, 2011, and 2010, respectively. The Plan provides, among other things, that participants in the Plan be able to direct the investment of their account balances within the Profit Sharing Plan into alternative investment funds. Participant deferrals under the salary reduction election may be matched by the employer based on a percentage to be determined annually by the employer.

NOTE 20 – COMMITMENTS AND CONTINGENCIES

Off-balance sheet commitments

The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. Such commitments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated balance sheets. The same credit policies are used in these commitments as for on-balance sheet instruments. The Company’s exposure to credit loss in the event of nonperformance by the other parties is represented by the contractual amount of the financial instruments. At December 31, 2012, the fair value of guarantees under commercial and standby letters of credit was $622,000. This amount represents the unamortized fee associated with these guarantees and is included in the consolidated balance sheet of the Company. This fair value will decrease over time as the existing commercial and standby letters of credit approach their expiration dates.

At December 31, 2012 and 2011, the Company had the following financial instruments outstanding, whose contract amounts represent credit risk:

	Contract Amount
(Dollars in thousands)	2012		2011
Commitments to grant loans	$	192,295	$	243,458
Unfunded commitments under lines of credit		2,372,971		1,773,601
Commercial and standby letters of credit		62,207		49,530

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to be drawn upon, the total commitment amounts generally represent future cash requirements. The Company evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the counterparty.

Unfunded commitments under commercial lines-of-credit, revolving credit lines and overdraft protection agreements are commitments for possible future extensions of credit to existing customers. Many of these types of commitments do not contain a specified maturity date and may not be drawn upon to the total extent to which the Company is committed.

Commercial and standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. These guarantees are primarily issued to support public and private borrowing arrangements, including commercial paper issuance, bond financing, and similar transactions. The credit risk involved in issuing letters or credit is essentially the same as that involved in extending loan facilities to customers and as such, are collateralized when necessary, generally in the form of marketable securities and cash equivalents.

Legal proceedings

The nature of the business of the Company’s banking and other subsidiaries ordinarily results in a certain amount of claims, litigation, investigations and legal and administrative cases and proceedings, all of which are considered incidental to the normal conduct of business. Some of these claims are against entities or assets of which the Company is a successor or acquired in business acquisitions, and certain of these claims will be covered by loss sharing agreements with the FDIC. The Company has asserted defenses to these litigation claims and, with respect to such legal proceedings, intends to continue to defend itself vigorously, litigating or settling cases according to management’s judgment as to what is in the best interest of the Company and its shareholders.

The Company assesses its liabilities and contingencies in connection with outstanding legal proceedings utilizing the latest information available. Where it is probable that the Company will incur a loss and the amount of the loss can be reasonably estimated, the Company records a liability in its consolidated financial statements. These legal reserves may be increased or decreased to reflect any relevant developments on a quarterly basis. Where a loss is not probable or the amount of loss is not estimable, the Company does not accrue legal reserves. While the outcome of legal proceedings is inherently uncertain, based on information currently available, advice of counsel and available insurance coverage, the Company’s management believes that it has established appropriate legal reserves. Any liabilities arising from pending legal proceedings are not expected to have a material adverse effect on the Company’s consolidated financial position, consolidated results of operations or consolidated cash flows. However, in the event of unexpected future developments, it is possible that the ultimate resolution of these matters, if unfavorable, may be material to the Company’s consolidated financial position, consolidated results of operations or consolidated cash flows.

NOTE 21 – RELATED PARTY TRANSACTIONS

In the ordinary course of business, the Company has granted loans to executive officers and directors and their affiliates amounting to $750,000 and $1,381,000 at December 31, 2012 and 2011, respectively. During the years ended December 31, 2012, 2011, and 2010, total principal additions were $252,000, $931,000, and $67,000, respectively. Total principal payments were $883,000, $317,000, and $444,000 for the years ended December 31, 2012, 2011, and 2010, respectively. Unfunded commitments to executive officers and directors and their affiliates totaled $390,000 and $131,000 at December 31, 2012 and 2011, respectively. None of the related party loans were classified as nonaccrual, past due, restructured or potential problem loans at December 31, 2012 or 2011.

Deposits from related parties held by the Company through IBERIABANK at December 31, 2012 and 2011 amounted to $6,155,000 and $5,070,000, respectively.

During 2012, available for sale securities with a market value of $1,085,000 at December 31, 2011 were transferred into the Level 2 fair value measurement category in the table above from the Level 3 category as disclosed at December 31, 2011. The security was issued by a municipal entity and was included in the Level 3 category at December 31, 2011 because their fair value was based on management’s estimate of the security’s fair value after recording an other-than-temporary impairment during the year ended December 31, 2011. At December 31, 2012, the fair value of this security was based on a trade price for similar assets, namely a similar security.

53

Gains and losses (realized and unrealized) included in earnings (or changes in net assets) during 2012 related to assets and liabilities measured at fair value on a recurring basis are reported in noninterest income or other comprehensive income as follows:

The tables above exclude the initial measurement of assets and liabilities that were acquired as part of the Florida Gulf, OMNI, Cameron, and Florida Trust Company acquisitions completed in 2012 and 2011. These assets and liabilities were recorded at their fair value upon acquisition in accordance with generally-accepted accounting principles and were not re-measured during the periods presented unless specifically required by generally accepted accounting principles. Acquisition date fair values represent either Level 2 fair value measurements (investment securities, OREO, property, equipment, and debt) or Level 3 fair value measurements (loans, deposits and core deposit intangible asset).

In accordance with the provisions of ASC Topic 310, the Company records loans considered impaired at their estimated fair value. A loan is considered impaired if it is probable the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. Fair value is measured at the estimated fair value of the collateral for collateral-dependent loans. Impaired non-covered loans with an outstanding balance of $7,269,000 were recorded at their fair value at December 31, 2012. These loans include a reserve of $880,000 included in the Company’s allowance for credit losses at December 31, 2012. Impaired non-covered loans with an outstanding balance of $4,532,000 were recorded at their fair value at December 31, 2011. These loans include a reserve of $2,186,000 included in the Company’s allowance for credit losses at December 31, 2011.

During the second quarter of 2012, the Company announced plans to close ten branches during the third and fourth quarters of 2012 as part of its business strategy. The Company has notified customers of these branches and has received the required regulatory approvals to proceed with closure. Seven of the branches are located in Florida, two in Louisiana, and one in Arkansas. Five of these branches are owned by the Company, and five of the branches are leased under operating lease agreements. The five branches owned by the Company had a book value of $7,778,000 at the time of the announcement. The Company reviewed the carrying amount of the owned properties and concluded it exceeded the fair value of these branches at that date. As a result, the Company recorded an impairment loss in other noninterest expense of $2,743,000 in its consolidated statement of comprehensive income for year ended December 31, 2012. After the impairment loss, the carrying value of the branches was $4,214,000 and is included in other real estate owned (as real estate acquired for development or resale), a component of other assets on the consolidated balance sheet.

54

Fair value of the branches was based on a third-party broker opinion of value using both a comparable sales and cash flow approach. The Company did not modify the third-party pricing information for unobservable inputs.

The Company did not record any liabilities at fair value for which measurement of the fair value was made on a nonrecurring basis during the years ended December 31, 2012 and 2011.

The Company may elect the fair value option, which permits the Company to choose to measure eligible financial assets and liabilities at fair value at specified election dates and recognize prospective changes in unrealized gains and losses on items for which the fair value option has been elected in earnings at each reporting date. The Company has currently chosen not to elect the fair value option for any items that are not already required to be measured at fair value in accordance with generally accepted accounting principles, and as such has not included any gains or losses in earnings for years ended December 31, 2012 and 2011.

NOTE 23 – FAIR VALUE OF FINANCIAL INSTRUMENTS

The estimated fair value of a financial instrument is the current amount that would be exchanged between willing parties, other than in a forced liquidation. Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for the Company’s various financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument. ASC Topic 825 excludes certain financial instruments and all non-financial instruments from its disclosure requirements. Accordingly, the aggregate fair value amounts presented may not necessarily represent the underlying fair value of the Company.

The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value:

Cash and cash equivalents

The carrying amounts of cash and cash equivalents approximate their fair value.

Investment securities

Securities are classified within Level 1 where quoted market prices are available in an active market. If quoted market prices are unavailable, fair value is estimated using pricing models or quoted prices of securities with similar characteristics, at which point the securities would be classified within Level 2 of the hierarchy. Inputs include securities that have quoted prices in active markets for identical assets.

Loans

The fair values of non-covered mortgage loans receivable are estimated based on present values using entry-value rates (the interest rate that would be charged for a similar loan to a borrower with similar risk at the indicated balance sheet date) at December 31, 2012 and 2011, weighted for varying maturity dates. Other non-covered loans receivable are valued based on present values using entry-value interest rates at December 31, 2012 and 2011 applicable to each category of loans, which would be classified within Level 3 of the hierarchy. Fair values of mortgage loans held for sale are based on commitments on hand from investors or prevailing market prices. Covered loans are measured using projections of expected cash flows, exclusive of the shared-loss agreements with the FDIC. Fair value of the covered loans included in the table below reflects the current fair value of these loans, which is based on an updated estimate of the projected cash flow as of the dates indicated. The fair value associated with the loans include estimates related to expected prepayments and the amount and timing of undiscounted expected principal, interest and other cash flows, which also would be classified within Level 3 of the hierarchy.

Accrued Interest Receivable and Accrued Interest Payable: The carrying amount of accrued interest approximates fair value because of the short maturity of these financial instruments.

FDIC Loss Share Receivable: The fair value is determined using projected cash flows from loss sharing agreements based on expected reimbursements for losses at the applicable loss sharing percentages based on the terms of the loss share agreements. Cash flows are discounted to reflect the timing and receipt of the loss sharing reimbursements from the FDIC. The fair value of the Company’s FDIC loss share receivable would be categorized within Level 3 of the hierarchy.

Deposits

The fair values of NOW accounts, money market deposits and savings accounts are the amounts payable on demand at the reporting date. Certificates of deposit were valued using a discounted cash flow model based on the weighted-average rate at December 31, 2012 and 2011 for deposits of similar remaining maturities. The fair value of the Company’s deposits would therefore be categorized within Level 3 of the fair value hierarchy.

Short-term borrowings

The carrying amounts of short-term borrowings maturing within ninety days approximate their fair values.

55

Long-term debt

The fair values of long-term debt are estimated using discounted cash flow analyses based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements. The fair value of the Company’s long-term debt would therefore be categorized within Level 3 of the fair value hierarchy.

Derivative instruments

Fair values for interest rate swap agreements are based upon the amounts required to settle the contracts. Fair values of the derivative instruments are estimated using prices of financial instruments with similar characteristics, and thus the instruments are classified within Level 2 of the fair value hierarchy.

Off-balance sheet items

The Company has outstanding commitments to extend credit and standby letters of credit. These off-balance sheet financial instruments are generally exercisable at the market rate prevailing at the date the underlying transaction will be completed. At December 31, 2012 and 2011, the fair value of guarantees under commercial and standby letters of credit was immaterial.

The estimated fair values and carrying amounts of the Company’s financial instruments are as follows at December 31:

Accrued interest payable		6,615		6,615		6,978		6,978

The fair value estimates presented herein are based upon pertinent information available to management as of December 31, 2012 and 2011. Although management is not aware of any factors that would significantly affect the estimated fair value amounts, such amounts have not been comprehensively revalued for purposes of these financial statements since that date and, therefore, current estimates of fair value may differ significantly from the amounts presented herein.

Capital Requirements And Other Regulatory Matters

Capital Requirements And Other Regulatory Matters

NOTE 18 – CAPITAL REQUIREMENTS AND OTHER REGULATORY MATTERS

The Company and IBERIABANK are subject to various regulatory capital requirements administered by the federal and state banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and IBERIABANK must meet specific capital guidelines that involve quantitative measures of their assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Prompt corrective action provisions are not applicable to bank holding companies.

Quantitative measures established by regulation to ensure capital adequacy require the Company and IBERIABANK to maintain minimum amounts and ratios of total and Tier 1 capital to risk-weighted assets and of Tier 1 capital to average assets. Management believes, as of December 31, 2012 and 2011, that the Company and IBERIABANK met all capital adequacy requirements to which they are subject.

As of December 31, 2012, the most recent notification from the Federal Deposit Insurance Corporation categorized IBERIABANK as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized, an institution must maintain minimum total risk-based, Tier 1 risk-based and Tier 1 leverage ratios as set forth in the following table. There are no conditions or events since the notification that management believes have changed either entity’s category. The Company’s and IBERIABANK’s actual capital amounts and ratios as of December 31, 2012 and 2011 are presented in the following table.

In June 2012, the Board of Governors of the Federal Reserve System (the “Federal Reserve”) approved three related notices of proposed rulemaking (the “NPRs”) relating to implementation of minimum capital requirements and a capital conservation buffer reflecting requirements of the Dodd-Frank Wall Street Reform and Consumer Protection Act (“Dodd-Frank Act”) and the Basel III international capital standards. The three NPRs are expected to be published jointly by the Federal Reserve, the FDIC, and the Office of the Comptroller of Currency after each agency has completed its approval process. If approved as proposed, the NPRs would be effective over a phased-in period from 2013 to 2019. The Company is in the process of evaluating the impact of the proposed rules on the Company and IBERIABANK.

Explanation of Certain Fair Value Adjustments

(1) The adjustment represents the write down of the book value of Florida Gulf’s investments to their estimated fair value based on fair values on the date of acquisition.

(2) The adjustment represents the write down of the book value of Florida Gulf’s loans to their estimated fair value based on current interest rates and expected cash flows which includes estimates of expected credit losses inherent in the portfolio.

(3) The adjustment represents the write down of the book value of Florida Gulf’s OREO properties to their estimated fair value at the acquisition date based on their appraised value, as adjusted for costs to sell.

(4) The adjustment represents the deferred tax asset recognized on the fair value adjustments of Florida Gulf’s acquired assets and assumed liabilities.

(5) The adjustment represents the write down of the book value of Florida Gulf’s property, equipment, and other assets to their estimated fair value at the acquisition date based on their appraised value.

(6) The adjustment is necessary because the weighted average interest rate of Florida Gulf’s CDs exceeded the cost of similar funding at the time of acquisition. The fair value adjustment will be amortized to reduce interest expense over the life of the portfolio, which is estimated at 60 months.

(7) The adjustment is necessary because the interest rate of Florida Gulf’s fixed rate borrowings exceeded current interest rates on similar borrowings.

Recent Accounting Pronouncements

NOTE 2 – RECENT ACCOUNTING PRONOUNCEMENTS

ASU No. 2011-04

In 2012, the Company adopted the provisions of ASU No. 2011-04, Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in US GAAP and IFRSs, which changes the wording used to describe many of the requirements in U.S. GAAP for measuring fair value and for disclosing information about fair value measurements. The amendments clarify that the Company should disclose quantitative information about the unobservable inputs used in a fair value measurement that is categorized within Level 3 of the fair value hierarchy. Requiring quantitative information does not change the objective of the requirement but increases the comparability of disclosures between disclosures under U.S. GAAP and IFRSs.

The disclosures required by this ASU are incorporated in Notes 22 and 23 in these consolidated financial statements.

ASU No. 2011-05

In 2012, the Company adopted the provisions of Accounting Standards Update (“ASU”) No. 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income, which increases the prominence of items reported in other comprehensive income and eliminates the option to report other comprehensive income as part of the statement of shareholders’ equity. The ASU requires that all nonowner changes in shareholders’ equity be presented in either a single continuous statement of comprehensive income or in two separate but consecutive statements. The adoption of this ASU did not change the items that are reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income. The adoption also did not change the option to present components of other comprehensive income either net of related tax effects or before related tax effects. The tax effect for each component must be disclosed in the notes to the consolidated financial statements or presented in the statement in which other comprehensive income is presented. The amendments also do not affect how earnings per share is calculated or presented.

The Company has chosen to present the nonowner changes in shareholders’ equity in a single continuous statement of comprehensive income in its consolidated financial statements. The adoption of the ASU in the current year affects the format and presentation of its consolidated financial statements but does not represent a departure from currently adopted accounting principles and thus the adoption did not have an effect on the Company’s operating results, financial position, or liquidity. The financial statements for the comparative prior period have been revised to conform to current period presentation.

ASU No. 2012-02

In 2012, the Company adopted the provisions of ASU No. 2012-02, Intangibles – Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment, which provides the Company with the option to make a qualitative assessment about the likelihood that an indefinite-lived intangible asset is impaired to determine whether it should perform a quantitative impairment test. The ASU also enhances the consistency of impairment testing guidance among long-lived asset categories by permitting the Company to assess qualitative factors to determine whether it is necessary to calculate the asset’s fair value when testing an indefinite-lived intangible asset for impairment, which is equivalent to the impairment testing requirements for other long-lived assets. In accordance with the amendments in this Update, an entity will have an option not to calculate annually the fair value of an indefinite-lived intangible asset if the entity determines that it is not more likely than not that the asset is impaired. Permitting the Company to assess qualitative factors when testing indefinite-lived intangible assets for impairment results in guidance that is similar to the goodwill impairment testing guidance in ASU No. 2011-08. The adoption of the ASU in the current year does not represent a departure from currently adopted accounting principles and thus the adoption did not have an effect on the Company’s operating results, financial position, or liquidity.

ASU No. 2012-06

In 2012, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2012-06, Business Combinations (Topic 805): Subsequent Accounting for an Indemnification Asset Recognized at the Acquisition Date as a Result of a Government-Assisted Acquisition of a Financial Institution, which clarifies the applicable guidance for subsequently measuring an indemnification asset recognized in a government-assisted acquisition of a financial institution that includes a loss-sharing agreement. The ASU addresses the diversity in practice in the interpretation of the terms “on the same basis” and “contractual limitations” used in accounting guidance. Accounting principles require that an indemnification asset recognized at the acquisition date as a result of a government-assisted acquisition of a financial institution involving an indemnification agreement shall be subsequently measured on the same basis as the indemnified item. The provisions of ASU No. 2012-06 clarify that, upon subsequent remeasurement of an indemnification asset, the effect of the change in expected cash flows of the indemnification agreement shall be amortized. Any amortization of changes in value is limited to the lesser of the contractual term of the indemnification agreement and the remaining life of the indemnified assets. The ASU does not affect the guidance relating to the recognition or initial measurement of an indemnification asset.

The provisions in this ASU are effective beginning with the Company’s first quarter of 2013, with early adoption permitted. Because the estimated lives of indemnification assets are an accounting estimate, the impact of the adoption of ASU No. 2012-06 will be prospective, meaning that changes in the estimated life will impact the future earnings of the Company. The rate of amortization of the indemnification assets by the Company has been estimated over the life of the underlying covered loans using a static spread to the rate earned on the covered loans. The adoption of ASU No. 2012-06 will change how the Company amortizes its indemnification assets. The Company currently expects to have higher future amortization in the near term and does not expect a material impact on its financial position and liquidity resulting from the adoption of this ASU.

ASU No. 2013-02

In February 2013, the FASB issued ASU No. 2013-06, Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, which requires the Company to report the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income on the Company’s consolidated statement of comprehensive income if the amount being reclassified is required under US GAAP to be reclassified in its entirety to net income. The ASU does not change the current requirements for reporting net income or other comprehensive income in the consolidated financial statements of the Company, but does require the Company to provide information about the amounts reclassified out of accumulated other comprehensive income by component.

The provisions in the ASU are effective prospectively beginning with the Company’s first quarter of 2013, with early adoption permitted. The adoption of the ASU affects the format and presentation of its consolidated financial statements and the footnotes to the consolidated financial statements, but does not represent a departure from currently adopted accounting principles and thus the adoption will not have an effect on the Company’s operating results, financial position, or liquidity.

During 2012, available for sale securities with a market value of $1,085,000 at December 31, 2011 were transferred into the Level 2 fair value measurement category in the table above from the Level 3 category as disclosed at December 31, 2011. The security was issued by a municipal entity and was included in the Level 3 category at December 31, 2011 because their fair value was based on management’s estimate of the security’s fair value after recording an other-than-temporary impairment during the year ended December 31, 2011. At December 31, 2012, the fair value of this security was based on a trade price for similar assets, namely a similar security.

Gains and losses (realized and unrealized) included in earnings (or changes in net assets) during 2012 related to assets and liabilities measured at fair value on a recurring basis are reported in noninterest income or other comprehensive income as follows:

The tables above exclude the initial measurement of assets and liabilities that were acquired as part of the Florida Gulf, OMNI, Cameron, and Florida Trust Company acquisitions completed in 2012 and 2011. These assets and liabilities were recorded at their fair value upon acquisition in accordance with generally-accepted accounting principles and were not re-measured during the periods presented unless specifically required by generally accepted accounting principles. Acquisition date fair values represent either Level 2 fair value measurements (investment securities, OREO, property, equipment, and debt) or Level 3 fair value measurements (loans, deposits and core deposit intangible asset).

In accordance with the provisions of ASC Topic 310, the Company records loans considered impaired at their estimated fair value. A loan is considered impaired if it is probable the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. Fair value is measured at the estimated fair value of the collateral for collateral-dependent loans. Impaired non-covered loans with an outstanding balance of $7,269,000 were recorded at their fair value at December 31, 2012. These loans include a reserve of $880,000 included in the Company’s allowance for credit losses at December 31, 2012. Impaired non-covered loans with an outstanding balance of $4,532,000 were recorded at their fair value at December 31, 2011. These loans include a reserve of $2,186,000 included in the Company’s allowance for credit losses at December 31, 2011.

During the second quarter of 2012, the Company announced plans to close ten branches during the third and fourth quarters of 2012 as part of its business strategy. The Company has notified customers of these branches and has received the required regulatory approvals to proceed with closure. Seven of the branches are located in Florida, two in Louisiana, and one in Arkansas. Five of these branches are owned by the Company, and five of the branches are leased under operating lease agreements. The five branches owned by the Company had a book value of $7,778,000 at the time of the announcement. The Company reviewed the carrying amount of the owned properties and concluded it exceeded the fair value of these branches at that date. As a result, the Company recorded an impairment loss in other noninterest expense of $2,743,000 in its consolidated statement of comprehensive income for year ended December 31, 2012. After the impairment loss, the carrying value of the branches was $4,214,000 and is included in other real estate owned (as real estate acquired for development or resale), a component of other assets on the consolidated balance sheet.

Fair value of the branches was based on a third-party broker opinion of value using both a comparable sales and cash flow approach. The Company did not modify the third-party pricing information for unobservable inputs.

The Company did not record any liabilities at fair value for which measurement of the fair value was made on a nonrecurring basis during the years ended December 31, 2012 and 2011.

The Company may elect the fair value option, which permits the Company to choose to measure eligible financial assets and liabilities at fair value at specified election dates and recognize prospective changes in unrealized gains and losses on items for which the fair value option has been elected in earnings at each reporting date. The Company has currently chosen not to elect the fair value option for any items that are not already required to be measured at fair value in accordance with generally accepted accounting principles, and as such has not included any gains or losses in earnings for years ended December 31, 2012 and 2011.

Fair Value Of Financial Instruments

12 Months Ended

Dec. 31, 2012

Fair Value Of Financial Instruments

NOTE 23 – FAIR VALUE OF FINANCIAL INSTRUMENTS

The estimated fair value of a financial instrument is the current amount that would be exchanged between willing parties, other than in a forced liquidation. Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for the Company’s various financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument. ASC Topic 825 excludes certain financial instruments and all non-financial instruments from its disclosure requirements. Accordingly, the aggregate fair value amounts presented may not necessarily represent the underlying fair value of the Company.

The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value:

Cash and cash equivalents

The carrying amounts of cash and cash equivalents approximate their fair value.

Investment securities

Securities are classified within Level 1 where quoted market prices are available in an active market. If quoted market prices are unavailable, fair value is estimated using pricing models or quoted prices of securities with similar characteristics, at which point the securities would be classified within Level 2 of the hierarchy. Inputs include securities that have quoted prices in active markets for identical assets.

Loans

The fair values of non-covered mortgage loans receivable are estimated based on present values using entry-value rates (the interest rate that would be charged for a similar loan to a borrower with similar risk at the indicated balance sheet date) at December 31, 2012 and 2011, weighted for varying maturity dates. Other non-covered loans receivable are valued based on present values using entry-value interest rates at December 31, 2012 and 2011 applicable to each category of loans, which would be classified within Level 3 of the hierarchy. Fair values of mortgage loans held for sale are based on commitments on hand from investors or prevailing market prices. Covered loans are measured using projections of expected cash flows, exclusive of the shared-loss agreements with the FDIC. Fair value of the covered loans included in the table below reflects the current fair value of these loans, which is based on an updated estimate of the projected cash flow as of the dates indicated. The fair value associated with the loans include estimates related to expected prepayments and the amount and timing of undiscounted expected principal, interest and other cash flows, which also would be classified within Level 3 of the hierarchy.

Accrued Interest Receivable and Accrued Interest Payable: The carrying amount of accrued interest approximates fair value because of the short maturity of these financial instruments.

FDIC Loss Share Receivable: The fair value is determined using projected cash flows from loss sharing agreements based on expected reimbursements for losses at the applicable loss sharing percentages based on the terms of the loss share agreements. Cash flows are discounted to reflect the timing and receipt of the loss sharing reimbursements from the FDIC. The fair value of the Company’s FDIC loss share receivable would be categorized within Level 3 of the hierarchy.

Deposits

The fair values of NOW accounts, money market deposits and savings accounts are the amounts payable on demand at the reporting date. Certificates of deposit were valued using a discounted cash flow model based on the weighted-average rate at December 31, 2012 and 2011 for deposits of similar remaining maturities. The fair value of the Company’s deposits would therefore be categorized within Level 3 of the fair value hierarchy.

Short-term borrowings

The carrying amounts of short-term borrowings maturing within ninety days approximate their fair values.

Long-term debt

The fair values of long-term debt are estimated using discounted cash flow analyses based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements. The fair value of the Company’s long-term debt would therefore be categorized within Level 3 of the fair value hierarchy.

Derivative instruments

Fair values for interest rate swap agreements are based upon the amounts required to settle the contracts. Fair values of the derivative instruments are estimated using prices of financial instruments with similar characteristics, and thus the instruments are classified within Level 2 of the fair value hierarchy.

Off-balance sheet items

The Company has outstanding commitments to extend credit and standby letters of credit. These off-balance sheet financial instruments are generally exercisable at the market rate prevailing at the date the underlying transaction will be completed. At December 31, 2012 and 2011, the fair value of guarantees under commercial and standby letters of credit was immaterial.

The estimated fair values and carrying amounts of the Company’s financial instruments are as follows at December 31:

	2012				2011
(Dollars in thousands)	Carrying Amount		Fair Value		Carrying Amount		Fair Value
Financial Assets
Cash and cash equivalents	$	970,977	$	970,977	$	573,296	$	573,296

The fair value estimates presented herein are based upon pertinent information available to management as of December 31, 2012 and 2011. Although management is not aware of any factors that would significantly affect the estimated fair value amounts, such amounts have not been comprehensively revalued for purposes of these financial statements since that date and, therefore, current estimates of fair value may differ significantly from the amounts presented herein.

CORRECTION OF AN ERROR IN THE FINANCIAL STATEMENTS

The Company has corrected its historical consolidated statements of cash flows for the years ended December 31, 2011 and 2010 for the miscalculation of certain activity between its operating and investing cash flows. The correction did not have an effect on the Company’s consolidated balance sheets, statements of comprehensive income, or statements of shareholders’ equity for those years. The error was identified in 2012 through the operation of the Company’s internal controls over financial reporting. Using accounting guidance provided in Accounting Standards Codification (“ASC”) Topic 250, the Company assessed these items and determined the error would be considered material to the consolidated statements of cash flows for the years ended December 31, 2011 and 2010. The error also impacts the consolidated statements of cash flows for each quarter in 2012 and 2011 as described in Note 26. As a result, the information included in these consolidated financial statements and footnotes includes the effect this correction has on the previously reported financial statements for those years.

The following table presents the effect this correction has on the Consolidated Statements of Cash Flows for the years ended December 31, 2011 and 2010.

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Material estimates that are susceptible to significant change in the near term are the allowance for credit losses, valuation of and accounting for loans covered by loss sharing arrangements with the FDIC and the related loss share receivable, valuation of and accounting for acquired loans, valuation of goodwill, intangible assets and other purchase accounting adjustments, and share-based compensation.

CONCENTRATION OF CREDIT RISKS

Most of the Company’s business activity is with customers located within the States of Louisiana, Florida, Arkansas, Alabama, Texas, and Tennessee. The Company’s lending activity is concentrated in its market areas in those states. The Company has emphasized originations of commercial loans and private banking loans, defined as loans to larger consumer clients. Repayments on loans are expected to come from cash flows of the borrower and/or guarantor. Losses on secured loans are limited by the value of the collateral upon default of the borrowers. The Company does not have any significant concentrations to any one industry or customer.

CASH AND CASH EQUIVALENTS

For purposes of presentation in the consolidated statements of cash flows, cash and cash equivalents are defined as cash, interest-bearing deposits and noninterest-bearing demand deposits at other financial institutions with original maturities less than three months. IBERIABANK may be required to maintain average balances on hand or with the Federal Reserve Bank to meet regulatory reserve and clearing requirements. At December 31, 2012 and 2011, the required reserve balances were $2,555,000 and $25,000, respectively. IBERIABANK had enough cash deposited with the Federal Reserve at December 31, 2012 and 2011 to cover the required reserve balance.

INVESTMENT SECURITIES

Debt securities that management has the ability and intent to hold to maturity are classified as held to maturity and carried at cost, adjusted for amortization of premiums and accretion of discounts using methods approximating the interest method. Securities not classified as held to maturity or trading, including equity securities with readily determinable fair values, are classified as available for sale and recorded at fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive income. Declines in the value of individual held to maturity and available for sale securities below their cost that are other than temporary are included in earnings as realized losses. In estimating other than temporary impairment losses, management considers 1) the length of time and the extent to which the fair value has been less than cost, 2) the financial condition and near-term prospects of the issuer, 3) the intent and ability of the Company to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value, and 4) for debt securities, the recovery of contractual principal and interest. Gains or losses on securities sold are recorded on the trade date, using the specific identification method.

LOANS HELD FOR SALE

Mortgage loans originated and intended for sale in the secondary market are carried at the lower of cost or estimated fair value. Net unrealized losses, if any, are recognized through a valuation allowance that is recorded as a charge to income. Loans held for sale have primarily been fixed rate single-family residential mortgage loans under contract to be sold in the secondary market. In most cases, loans in this category are sold within thirty days. These loans are generally sold with the mortgage servicing rights released. Buyers generally have recourse to return a purchased loan to the Company under limited circumstances. Recourse conditions may include early payment default, breach of representations or warranties, and documentation deficiencies. During 2012 and 2011, an insignificant number of loans were returned to the Company.

LOANS (EXCLUDING ACQUIRED LOANS)

The Company grants mortgage, commercial and consumer loans to customers. Except for loans acquired, loans receivable that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are stated at the unpaid principal balances, less the allowance for credit losses and net deferred loan origination fees and unearned discounts.

Interest income on loans is accrued over the term of the loans based on the principal balance outstanding. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield, using the effective interest method.

The accrual of interest on loans is discontinued at the time the loan is 90 days delinquent unless the credit is well-secured and in process of collection. Mortgage, credit card and other personal loans are typically charged down to net collateral value, less cost to sell, no later than 180 days past due. Past due status is based on the contractual terms of loans. In all cases, loans are placed on nonaccrual status or charged off at an earlier date if collection of principal or interest is considered doubtful.

The Company’s covered loan portfolio and non-covered loan portfolio, which are delineated between a) non-covered loans, excluding acquired loans, and b) acquired loans, are disaggregated into portfolio segments for purposes of determining the allowance for credit losses. The Company’s portfolio segments include commercial real estate, commercial business, mortgage, and consumer. The Company further disaggregates each commercial real estate, mortgage, and consumer portfolio segment into classes for purposes of monitoring and assessing credit quality based on certain risk characteristics. Classes within each commercial real estate portfolio segment include commercial real estate construction and commercial real estate – other. Classes within each mortgage portfolio segment include mortgage – prime and mortgage – subprime. Classes within each consumer portfolio segment include indirect auto, credit card, home equity, and consumer – other. Each commercial business portfolio segment is also considered a class.

Credit Quality

The Company utilizes an asset risk classification system in accordance with guidelines established by the Federal Reserve Board as part of its efforts to monitor commercial asset quality. “Special mention” loans are defined as loans where known information about possible credit problems of the borrower cause management to have some doubt as to the ability of these borrowers to comply with the present loan repayment terms and which may result in future disclosure of these loans as nonperforming. For assets with identified credit issues, the Company has two primary classifications for problem assets: “substandard” and “doubtful.” Substandard assets have one or more defined weaknesses and are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Doubtful assets have the weaknesses of substandard assets with the additional characteristic that the weaknesses make collection or liquidation in full satisfaction of the loan balance outstanding questionable and there is a high probability of loss based on currently existing facts, conditions and values. Loans classified as “Pass” do not meet the criteria set forth for special mention, substandard, or doubtful classification and are not considered criticized. Asset risk classifications are periodically reviewed and changed if, in the opinion of management, the risk profile of the customer has changed since the last review of the loan relationship.

A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. The impairment loss is measured on a loan by loan basis for commercial and construction loans by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral if the loan is collateral dependent.

In general, all interest accrued but not collected for loans that are placed on nonaccrual status or charged off is reversed against interest income. The interest on these loans is accounted for on the cash-basis method or cost-recovery method, until qualifying for a return to accrual status. Loans are returned to accrual status when all principal and interest amounts contractually due are brought current and future payments are reasonably assured.

Troubled Debt Restructurings

During the course of its lending operations, the Company periodically grants concessions to its customers in an attempt to protect as much of its investment as possible and minimize risk of loss. These concessions may include restructuring the terms of a customer loan to alleviate the burden of the customer’s near-term cash requirements. In order to be considered a troubled debt restructuring (“TDR”), the Company must conclude that the restructuring constitutes a concession and the customer is experiencing financial difficulties. The Company defines a concession to the customer as a modification of existing terms for economic or legal reasons that it would otherwise not consider. The concession is either granted through an agreement with the customer or is imposed by a court or law. Concessions include modifying original loan terms to reduce or defer cash payments required as part of the loan agreement, including but not limited to:

• a reduction of the stated interest rate for the remaining original life of the debt,

• extension of the maturity date or dates at a stated interest rate lower than the current market rate for new debt with similar risk characteristics,

• reduction of the face amount or maturity amount of the debt as stated in the agreement, or

• reduction of accrued interest receivable on the debt.

In its determination of whether the customer is experiencing financial difficulties, the Company considers numerous indicators, including, but not limited to:

• whether the customer is currently in default on its existing loan, or is in an economic position where it is probable the customer will be in default on its loan in the foreseeable future without a modification,

• whether the customer has declared or is in the process of declaring bankruptcy,

• whether there is substantial doubt about the customer’s ability to continue as a going concern,

• whether, based on its projections of the customer’s current capabilities, the Company believes the customer’s future cash flows will be insufficient to service the debt, including interest, in accordance with the contractual terms of the existing agreement for the foreseeable future, and

• whether, without modification, the customer cannot obtain sufficient funds from other sources at an effective interest rate equal to the current market rate for similar debt for a nontroubled debtor.

If the Company concludes that both a concession has been granted and the concession was granted to a customer experiencing financial difficulties, the Company identifies the loan as a TDR. For purposes of the determination of an allowance for credit losses for TDRs, the Company considers a loss probable on the loan, which is reviewed for specific impairment in accordance with the Company’s allowance for loan loss methodology. If it is determined that losses are probable on such TDRs, either because of delinquency or other credit quality indicator, the Company establishes specific reserves for these loans. For additional information on the Company’s allowance for credit losses, see Note 7 to these consolidated financial statements.

ACQUIRED LOANS AND RELATED FDIC LOSS SHARE RECEIVABLE

The Company accounts for its acquisitions under the purchase method, where all identifiable assets acquired, including loans, are recorded at fair value. No allowance for credit losses related to the acquired loans is recorded on the acquisition date as the fair value of the loans acquired incorporates assumptions regarding credit risk.

Loans acquired are recorded at fair value in accordance with the fair value methodology consistent with the exit price concept and exclusive of the shared-loss agreements with the FDIC from certain of the Company’s acquisitions in 2010 and 2009. The fair value estimates associated with the loans include estimates related to discount rates, expected prepayments and the amount and timing of undiscounted expected principal, interest and other cash flows. Credit discounts are included in the determination of fair value: therefore, an allowance for credit losses is not recorded at the acquisition date. At the time of acquisition, the Company estimated the fair value of the total acquired loan portfolio by segregating the total portfolio into loan pools with similar characteristics, which included:

• whether the loan was performing according to contractual terms at the time of acquisition,

• the loan type based on regulatory reporting guidelines, namely whether the loan was a mortgage, consumer, or commercial loan

• the nature of collateral,

• the interest rate type, whether fixed or variable rate, and

• the loan payment type, primarily whether the loan was amortizing or interest-only.

From these pools, the Company used certain loan information, including outstanding principal balance, estimated expected losses, weighted average maturity, weighted average term to re-price (if a variable rate loan), weighted average margin, and weighted average interest rate to estimate the expected cash flow for each loan pool.

Acquired loans are evaluated at acquisition and classified as purchase impaired or purchased non-impaired. Purchased impaired loans reflect credit deterioration since origination to the extent that it is probable at the time of acquisition that the Company will be unable to collect all contractually required payments. For purchased impaired loans, expected cash flows at the acquisition date in excess of the fair value of loans are recorded as interest income over the life of the loans using a level yield method if the timing and amount of future cash flows is reasonably estimable.

Subsequent to acquisition, the Company performs cash flow re-estimations at least quarterly for each purchased impaired loan and/or loan pool. Increases in estimated cash flows above those expected at acquisition are recognized on a prospective basis as interest income over the remaining life of the pool. Decreases in expected cash flows subsequent to acquisition result in recognition of a provision for credit loss.

Acquired loans are placed on nonaccrual status when the Company cannot reasonably estimate cash flows on a loan or loan pool.

Pursuant to an AICPA letter dated December 18, 2009, the AICPA summarized the SEC staff’s view regarding the accounting in subsequent periods for discount accretion associated with loan receivables acquired in a business combination or asset purchase. Regarding the accounting for such loan receivables that, in the absence of further standard setting, the AICPA understands the SEC staff would not object to an accounting policy based on contractual cash flows (ASC Topic 310-20 approach) or an accounting policy based on expected cash flows (ASC 310-30 approach). The Company believes analogizing to ASC Topic 310-30 is the more appropriate option to follow in accounting for the fair value discount. However, in cases where a loan is acquired at a premium or slight discount, the Company believes that the contractual yield approach outlined in ASC Topic 310-20 is the more appropriate approach to apply.

FDIC loss share receivable

Because the FDIC will reimburse the Company for certain loans acquired in 2009 and 2010 should the Company experience a loss, an indemnification asset is recorded at fair value at the acquisition date. The indemnification asset is recognized at the same time as the indemnified loans, and measured on the same basis, subject to collectability or contractual limitations. The shared loss agreements on the acquisition date reflect the reimbursements expected to be received from the FDIC, using an appropriate discount rate, which reflects counterparty credit risk and other uncertainties.

The shared loss agreements continue to be measured on the same basis as the related indemnified loans, and the loss share receivable is impacted by changes in estimated cash flows associated with these loans. Deterioration in the credit quality of the acquired loans and related expected cash flows (immediately recorded as an adjustment to the allowance for credit losses) would immediately increase the loss share receivable, with the offset recorded through the consolidated statement of income. Increases in the credit quality of the acquired loans and related cash flows (reflected as an adjustment to yield and accreted into income over the remaining life of the loans) decrease the basis of the shared loss agreements, with such decrease being amortized into income over 1) the life of the loan or 2) the life of the shared loss agreements, whichever is shorter. Loss assumptions used to measure the basis of the indemnified loans are consistent with the loss assumptions used to measure the indemnification asset. Fair value accounting incorporates into the fair value of the indemnification asset an element of the time value of money, which is accreted back into income over the life of the shared loss agreements.

Upon the collection from the FDIC of an incurred loss the indemnification asset will be reduced by the amount owed by the FDIC. A corresponding claim receivable is established when a loss is incurred and recorded in other assets until cash is received from the FDIC.

For further discussion of the Company’s acquisitions and loan accounting, see Note 4 and Note 6 to the consolidated financial statements.

ALLOWANCE FOR CREDIT LOSSES

The allowance for credit losses represents management’s best estimate of probable credit losses inherent in the loan portfolios and off-balance sheet lending commitments at the balance-sheet date. The allowance for credit losses is maintained at a level the Company considers appropriate and is based on quarterly assessments and evaluations of the collectability and historical loss experience, including both industry and Company specific considerations. While management uses the best information available to establish the allowance for credit losses, future adjustments may be necessary if economic conditions differ substantially from the assumptions used in determining the allowance or, if required by regulators, based upon information available to them at the time of their examinations, or if mandated by revisions to, new interpretations of, or issuance of new accounting standards. See Note 7 for an analysis of the Company’s allowance for credit losses by portfolio and portfolio segment, and credit quality information by class. The entire amount of the allowance for credit losses is available to absorb losses on any category or lending-related commitment for non-acquired loans. The allowance related to acquired loans represents management’s best estimate of cumulative impairment as described further in “Purchase Impaired Loans (Acquired Loans)”.

The Company’s strategy for credit risk management includes a combination of conservative exposure limits, which are significantly below legal lending limits and conservative underwriting, documentation and collection standards. The strategy emphasizes geographic, industry, and customer diversification within the Company’s operating footprint, regular credit examinations, and regular management reviews of large credit exposures and loans experiencing credit quality deterioration.

The Company has not substantively changed any material aspect in its overall approach of determining the current year allowance for credit losses. There have been no material changes in criteria or estimation techniques as compared to prior periods that impacted the determination of the current allowance for credit losses.

Allowance for credit losses discussion below includes discussion specific to loans accounted for under the contractual yield method, referred to as “contractual loans”, and loans accounted for as acquired credit impaired loans.

Contractual Loans (Excluding Acquired Loans)

Contractual loans represent loans accounted for under the contractual yield method. The Company’s contractual loans include loans originated by the Company and acquired loans that are not accounted for as acquired credit impaired loans, typically referred to as legacy loans. Credit losses on contractual loans are charged and recoveries are credited to the allowance for credit losses. Provisions for loan losses are based on the Company’s review of historical industry and Company specific loss experience, and factors that management determines should be considered in estimating probable credit losses.

Loans identified as impaired are subject to individual quarterly review for potential loss. The Company considers the current value of collateral, credit quality of any guarantees, the guarantor’s liquidity and willingness to cooperate, and other factors when evaluating whether an individual loan is impaired. Other factors may include the industry and geographic location of the borrower, size and financial condition of the borrower, cash flow and leverage of the borrower, and evaluation of the borrower’s management. When individual loans are impaired, allowances are estimated based on management’s assessment of the borrower’s ability to repay the loan given the availability of collateral and other sources of cash flow, including evaluation of available legal options. Allowances for individually impaired loans are estimated based on the present value of expected future cash flows discounted at the loan’s effective interest rate, fair value of the underlying collateral or readily observable secondary market values. Collectability of principal and interest is evaluated in assessing the need for a loss accrual.

The Company also estimates reserves for collective impairment that reflect an estimated measurement of losses related to loans not subject to individual review as of the balance sheet date. Such loans are grouped in homogenous pools or segments, which are consistent with the segments and classes described above. Embedded loss rates are derived from migration analyses, which track net charge-off experience sustained on loans according to their risk grade, and may be adjusted for Company-specific and/or industry factors. Loss rates are reviewed quarterly and adjusted as management deems necessary based on changing borrower and/or collateral conditions and actual collections and charge-off experience.

Based on observations made through a qualitative review, management may apply qualitative adjustments to the quantitatively determined loss estimates at a pool and/or portfolio segment level as deemed appropriate. Primary qualitative and environmental factors that may not be directly reflected in quantitative estimates include:

• asset quality trends,

• changes in lending and risk management practices and procedures

• trends in the nature and volume of the loan portfolio, including the existence and effect of any portfolio concentrations

• changes in experience and depth of lending staff

• legal, regulatory and competitive environment

• national and regional economic trends

• data availability and applicability

Changes in these factors are considered in determining the directional consistency of changes in the allowance for credit losses. The impact of these factors on the Company’s qualitative assessment of the allowance for credit losses can change from period to period based on management’s assessment of the extent to which these factors are already reflected in historic loss rates. The uncertainty inherent in the estimation process is also considered in evaluating the allowance for credit losses.

Purchased Impaired Loans (Acquired Loans)

Purchased impaired loans represent loans acquired by the Company, which are accounted in accordance with ASC 310-30. Credit losses incurred subsequent to acquisition are charged to the allowance for credit losses. Recoveries are credited to the allowance for credit losses to the extent the losses were incurred subsequent to acquisition. Recoveries related to credit losses incurred prior to acquisition are reflected as prospective adjustments to yield, which are accreted to income over the remaining life of the associated pool of loans. Provisions for credit losses are based on the Company’s determination of the timing and amount of expected cash flows. Provisions for credit losses associated with loans covered by loss share agreements with the FDIC are partially offset by increases in the FDIC loss share receivable.

The allowance for credit losses related to loans accounted for as purchased impaired loans is based on management’s re-estimation of expected cash flows for each loan pool. An allowance for credit losses is established to the extent that the expected cash flows of a loan pool have decreased since acquisition.

OFF-BALANCE SHEET CREDIT RELATED FINANCIAL INSTRUMENTS

The Company accounts for its guarantees in accordance with the provisions of ASC Topic 460. In the ordinary course of business, the Company has entered into commitments to extend credit, including commitments under credit card arrangements, commercial letters of credit and standby letters of credit. Such financial instruments are recorded when they are funded.

DERIVATIVE FINANCIAL INSTRUMENTS

ASC Topic 815 requires that all derivatives be recognized as assets or liabilities in the balance sheet at fair value. The Company may enter into derivative contracts to manage exposure to interest rate risk or to meet the financing and/or investing needs of its customers.

In the course of its business operations, the Company is exposed to certain risks, including interest rate, liquidity, and credit risk. The Company manages its risks through the use of derivative financial instruments, primarily through management of exposure due to the receipt or payment of future cash amounts based on interest rates. The Company’s derivative financial instruments manage the differences in the timing, amount, and duration of expected cash receipts and payments.

The primary types of derivatives used by the Company include interest rate swap agreements, forward sales contracts, interest rate lock commitments, and written and purchased options.

Hedging Activities

As part of its activities to manage interest rate risk due to interest rate movements, the Company has engaged in interest rate swap transactions to manage exposure to interest rate risk through modification of the Company’s net interest sensitivity to levels deemed to be appropriate. The Company utilizes these interest rate swap agreements to convert a portion of its variable-rate debt to a fixed rate (cash flow hedge). Interest rate swaps are contracts in which a series of interest rate flows are exchanged over a prescribed period. The notional amount on which the interest payments are based is not exchanged.

Because the swap agreements used to manage interest rate risk have been designated as hedging exposure to variable cash flows of a forecasted transaction, the effective portion of the derivative’s gain or loss is initially reported as a component of other comprehensive income and subsequently reclassified into earnings when the forecasted transaction affects earnings or when the hedge is terminated. The ineffective portion of the gain or loss is reported in earnings immediately.

In applying hedge accounting for derivatives, the Company establishes a method for assessing the effectiveness of the hedging derivative and a measurement approach for determining the ineffective aspect of the hedge upon the inception of the hedge. These methods are consistent with the Company’s approach to managing risk.

Other Derivative Instruments

Interest rate swap agreements

In addition to using derivative instruments as an interest rate risk management tool, the Company also enters into derivative instruments to help its commercial customers manage their exposure to interest rate fluctuations. To mitigate the interest rate risk associated with these customer contracts, the Company enters into offsetting derivative contract positions. The Company manages its credit risk, or potential risk of default by its commercial customers, through credit limit approval and monitoring procedures.

For interest rate swap agreements that are not designated as hedging instruments, changes in the fair value of the derivatives are recognized in earnings immediately.

Rate lock commitments

The Company enters into commitments to originate loans intended for sale whereby the interest rate on the prospective loan is determined prior to funding (“rate lock commitments”). A rate lock is given to a borrower, subject to conditional performance obligations, for a specified period of time that typically does not exceed 60 days. Simultaneously with the issuance of the rate lock to the borrower, a rate lock is received from an investor for a best efforts or mandatory delivery of the loan. Under the terms of the best efforts delivery lock, the investor commits to purchase the loan at a specified price, provided the loan is funded and delivered prior to a specified date and provided that the credit and loan characteristics meet pre-established criteria for such loans. Rate lock commitments on mortgage loans that are intended to be sold are considered to be derivatives. Accordingly, such commitments are recorded at fair value as derivative assets or liabilities, with changes in fair value recorded in mortgage income.

Equity-indexed certificates of deposit

IBERIABANK offers its customers a certificate of deposit that provides the purchaser a guaranteed return of principal at maturity plus potential return, which allows IBERIABANK to identify a known cost of funds. The rate of return is based on the performance of a basket of publically traded stocks that represent a variety of industry segments. Because it is based on an equity index, the rate of return represents an embedded derivative that is not clearly and closely related to the host instrument and is to be accounted for separately. Accordingly, the certificate of deposit is separated into two components: a zero coupon certificate of deposit (the host instrument) and a written option purchased by the depositor (an embedded derivative). The discount on the zero coupon deposit is amortized over the life of the deposit, and the written option is carried at fair value on the Company’s consolidated balance sheet, with changes in fair value recorded through earnings. IBERIABANK offsets the risks of the written option by purchasing an option with terms that mirror the written option and that is also carried at fair value on the Company’s consolidated balance sheet.

PREMISES AND EQUIPMENT

Land is carried at cost. Buildings, furniture, fixtures, and equipment are carried at cost, less accumulated depreciation computed on a straight line basis over the estimated useful lives of 10 to 40 years for buildings and 3 to 15 years for furniture, fixtures and equipment. Capitalized leasehold improvements are amortized over the length of the initial lease agreement or their useful life, whichever is shorter.

OTHER REAL ESTATE

Other real estate includes all real estate, other than bank premises used in bank operations, owned or controlled by the Company, including real estate acquired in settlement of loans. Properties are recorded at the balance of the loan (which is the pro-rata carrying value of loans accounted for in accordance with ASC 310-30) or at estimated fair value less estimated selling costs, whichever is less, at the date acquired. Subsequent to foreclosure, management periodically performs valuations and the assets are carried at the lower of cost or fair value less estimated selling costs. Revenue and expenses from operations, gain or loss on sale and changes in the valuation allowance are included in net expenses from foreclosed assets.

For further discussion of the Company’s other real estate owned, see Note 11 to the consolidated financial statements.

GOODWILL AND OTHER INTANGIBLE ASSETS

Goodwill

Goodwill is accounted for in accordance with ASC Topic 350, and accordingly is not amortized but is evaluated at least annually for impairment. As part of its testing, the Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the Company determines the fair value of a reporting unit is less than its carrying amount using these qualitative factors, the Company compares the fair value of goodwill with its carrying amount, and then measures impairment loss by comparing the implied fair value of goodwill with the carrying amount of that goodwill.

Title Plant

The Company records its title plant assets in accordance with ASC Topic 950. Under ASC Topic 950, costs incurred to construct a title plant, including the costs incurred to obtain, organize, and summarize historical information, are capitalized until the title plant can be used to perform title searches. Purchased title plant, including a purchased undivided interest in title plant, is recorded at cost at the date of acquisition. For title plant acquired separately or as part of a company acquisition, cost is measured as the fair value of the consideration given. Capitalized costs of title plant are not depreciated or charged to income unless circumstances indicate that the carrying amount of the title plant has been impaired. Impairment identifiers include a change in legal requirements or statutory practices, identification of obsolescence, and abandonment of the title plant, among other identifiers.

Intangible assets subject to amortization

The Company’s acquired intangible assets that are subject to amortization include core deposit intangibles, amortized on a straight line or accelerated basis over a 10 year average life and a customer relationship intangible asset, amortized on an accelerated basis over a 9.5 year life.

TRANSFERS OF FINANCIAL ASSETS

Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when 1) the assets have been isolated from the Company, 2) the transferee obtains the right, free of conditions that constrain it from taking advantage of that right, to pledge or exchange the transferred assets, and 3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Should the transfer not meet these three criteria, the transaction is treated as a secured financing.

INCOME TAXES

The Company and all subsidiaries file a consolidated federal income tax return on a calendar year basis. The Company files income tax returns in the U.S. federal jurisdiction and various state jurisdictions through IBERIABANK, LTC and their subsidiaries. In lieu of Louisiana state income tax, IBERIABANK is subject to the Louisiana bank shares tax, which is included in noninterest expense or income tax expense in the Company’s consolidated financial statements. With few exceptions, the Company is no longer subject to U.S. federal, state or local income tax examinations for years before 2009.

Deferred income tax assets and liabilities are determined using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is determined based on the tax effects of the temporary differences between the book and tax bases of the various balance sheet assets and liabilities and gives current recognition to changes in tax rates and laws. The measurement of deferred tax assets is reduced, if necessary, by the amount of any tax benefits that, based on available evidence, are not expected to be realized.

The Company recognizes interest and penalties accrued related to unrecognized tax benefits, if applicable, in noninterest expense.

STOCK COMPENSATION PLANS

The Company issues stock options and restricted stock under various plans to directors, officers and other key employees. The Company accounts for its stock compensation plans in accordance with ASC Topics 718 and 505. Under those provisions, the Company has adopted a fair value based method of accounting for employee stock compensation plans, whereby compensation cost is measured at the grant date based on the value of the award and is recognized on a straight-line basis over the service period, which is usually the vesting period, taking into account retirement eligibility. As a result, compensation expense relating to stock options and restricted stock is reflected in net income as part of “Salaries and employee benefits” on the consolidated statements of income. The Company’s practice has been to grant options at no less than the fair market value of the stock at the grant date.

See Note 19 for additional information on the Company’s share-based compensation plans.

EARNINGS PER COMMON SHARE

Basic earnings per share represents income available to common shareholders divided by the weighted average number of common shares outstanding during the period. Diluted earnings per share reflect additional common shares that would have been outstanding if dilutive potential common shares, in the form of stock options, had been issued, as well as any adjustment to income that would result from the assumed issuance. Participating common shares issued by the Company relate to unvested outstanding restricted stock awards, the earnings allocated to which are used in determining income available to common shareholders under the two-class method.

See Note 3 for additional information on the Company’s calculation of earnings per share.

TREASURY STOCK

The purchase of the Company’s common stock is recorded at cost. At the date of retirement or subsequent reissuance, treasury stock is reduced by the cost of such stock with differences recorded in additional paid-in capital or retained earnings, as applicable.

COMPREHENSIVE INCOME

Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income. Although certain changes in assets and liabilities, such as unrealized gains and losses on available for sale securities and cash flow hedges, are reported as a separate component of the equity section of the balance sheet, such items, along with net income, are components of comprehensive income.

SEGMENTS

All of the Company’s banking operations are considered by management to be aggregated in one reportable operating segment. Because the overall banking operations comprise substantially all of the consolidated operations and none of the Company’s other subsidiaries, either individually or in the aggregate, meet quantitative materiality thresholds, no separate segment disclosures are presented in these consolidated financial statements. The Company has invested in its financial reporting infrastructure to report financial information associated with performance of lines of business within the banking operating segment. The Company anticipates reporting this information sometime in 2013.

FAIR VALUE MEASUREMENTS

The Company estimates fair value based on the assumptions market participants would use when selling an asset or transferring a liability and characterizes such measurements within the fair value hierarchy based on the inputs used to develop those assumptions and measure fair value. The hierarchy requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows:

• Level 1 – Quoted prices in active markets for identical assets or liabilities.

• Level 2 – Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

• Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs.

A description of the valuation methodologies used for instruments measured at fair value follows, as well as the classification of such instruments within the valuation hierarchy.

Securities available for sale

Securities are classified within Level 1 where quoted market prices are available in an active market. Inputs include securities that have quoted prices in active markets for identical assets. If quoted market prices are unavailable, fair value is estimated using quoted prices of securities with similar characteristics, at which point the securities would be classified within Level 2 of the hierarchy. Examples may include certain collateralized mortgage and debt obligations.

Mortgage loans held for sale

As of December 31, 2012, the Company has $267,475,000 of conforming mortgage loans held for sale. Mortgage loans originated and held for sale are carried at the lower of cost or estimated fair value. The Company obtains quotes or bids on these loans directly from purchasing financial institutions. Mortgage loans held for sale that were recorded at estimated fair value are included in the table in Note 22.

Impaired loans

Loans are measured for impairment using the methods permitted by ASC Topic 310. Fair value measurements are used in determining impairment using either the loan’s obtainable market price, if available (Level 1) or the fair value of the collateral if the loan is collateral dependent (Level 2). Measuring the impairment of loans using the present value of expected future cash flows, discounted at the loan’s effective interest rate, is not considered a fair value measurement. Fair value of the collateral is determined by appraisals or independent valuation.

Other real estate owned

Fair values of OREO at December 31, 2012 are determined by sales agreement or appraisal, and costs to sell are based on estimation per the terms and conditions of the sales agreement or amounts commonly used in real estate transactions. Inputs include appraisal values on the properties or recent sales activity for similar assets in the property’s market, and thus OREO measured at fair value would be classified within Level 2 of the hierarchy. The Company included property write-downs of $6,409,000, $7,250,000, and $2,943,000 in earnings for the years ended December 31, 2012, 2011, and 2010, respectively.

Derivative financial instruments

The Company utilizes interest rate swap agreements to convert a portion of its variable-rate debt to a fixed rate (cash flow hedge). The Company also enters into commitments to originate loans whereby the interest rate on the prospective loan is determined prior to funding (“rate lock commitments”). Rate lock commitments on mortgage loans that are intended to be sold are considered to be derivatives. The Company offers its customers a certificate of deposit that provides the purchaser a guaranteed return of principal at maturity plus potential return, which allows the Company to identify a known cost of funds. The rate of return is based on an equity index, and as such represents an embedded derivative. Fair value of interest rate swaps, interest rate lock commitments, and equity-linked written and purchased options are estimated using prices of financial instruments with similar characteristics, and thus are classified within Level 2 of the fair value hierarchy.

[1] The adjustment represents the write down of the book value of Florida Gulf's investments to their estimated fair value based on fair values on the date of acquisition.

[2] The adjustment represents the write down of the book value of Florida Gulf's loans to their estimated fair value based on current interest rates and expected cash flows which includes estimates of expected credit losses inherent in the portfolio.

[3] The adjustment represents the write down of the book value of Florida Gulf's OREO properties to their estimated fair value at the acquisition date based on their appraised value, as adjusted for costs to sell.

[4] The adjustment represents the deferred tax asset recognized on the fair value adjustments of Florida Gulf's acquired assets and assumed liabilities.

[5] The adjustment represents the write down of the book value of Florida Gulf's property, equipment, and other assets to their estimated fair value at the acquisition date based on their appraised value.

[6] The adjustment is necessary because the weighted average interest rate of Florida Gulf's CDs exceeded the cost of similar funding at the time of acquisition. The fair value adjustment will be amortized to reduce interest expense over the life of the portfolio, which is estimated at 60 months.

[7] The adjustment is necessary because the interest rate of Florida Gulf's fixed rate borrowings exceeded current interest rates on similar borrowings.

At December 31, 2012 and 2011, the Company was required to post $2,650,000 and $1,210,000 in cash as collateral for its derivative transactions, which is included in interest-bearing deposits in banks on the Company’s consolidated balance sheets. The Company does not anticipate additional assets will be required to be posted as collateral, nor does it believe additional assets would be required to settle its derivative instruments immediately if contingent features were triggered at December 31, 2012. As permitted by generally-accepted accounting principles, the Company does not offset fair value amounts recognized for the right to reclaim cash collateral or the obligation to return cash collateral against recognized fair value amounts of derivatives executed with the same counterparty under a master netting agreement.

During the years ended December 31, 2012 and 2011, the Company has not reclassified into earnings any gain or loss as a result of the discontinuance of cash flow hedges because it was probable the original forecasted transaction would not occur by the end of the originally specified term.

At December 31, 2012, the fair value of derivatives that will mature within the next twelve months is $788,000. The Company does not expect to reclassify any amount from accumulated other comprehensive income into interest income over the next twelve months for derivatives that will be settled.

At December 31, 2012 and 2011, and for the years then ended, the information pertaining to the effect of the hedging instruments on the consolidated financial statements is as follows.

Treasury share repurchases

Share repurchases may be made from time to time, on the open market or in privately negotiated transactions. Such repurchases are authorized by the Board of Directors through a share repurchase program and are executed at the discretion of the management of the Company. The approved share repurchase program does not obligate the Company to repurchase any dollar amount or number of shares, and the program may be extended, modified, suspended, or discontinued at any time. Stock repurchases generally are affected through open market purchases, and may be made through unsolicited negotiated transactions. The timing of these repurchases will depend on market conditions and other requirements.

In October 2011, the Board of Directors authorized the repurchase of up to 900,000 shares of common stock. The following table details these purchases during 2012 and is based on the settlement date of the transactions. The average price paid per share includes commissions paid. No shares were repurchased during the months not presented in the table.

Goodwill And Other Acquired Intangible Assets

Goodwill And Other Acquired Intangible Assets

NOTE 10 – GOODWILL AND OTHER ACQUIRED INTANGIBLE ASSETS

Goodwill

Changes to the carrying amount of goodwill for the years ended December 31, 2012 and 2011 are provided in the following table.

(Dollars in thousands)	Amount
Balance, December 31, 2010	$	234,228
Goodwill acquired during the year		135,583
Balance, December 31, 2011		369,811
Goodwill acquired during the period		32,420
Goodwill adjustment to correct an immaterial error		(359	)
Balance, December 31, 2012	$	401,872

The goodwill acquired during the year ended December 31, 2011 was a result of the OMNI, Cameron, and Florida Trust Company acquisitions, and the goodwill acquired during the year ended December 31, 2012 was a result of the Florida Gulf acquisition discussed further in Note 4.

The goodwill adjustment in 2012 is a result of the Company’s revised goodwill recorded on its OMNI and Cameron acquisitions. The Company has recorded the adjustment to account for the impact of an immaterial error in accounting for its OMNI and Cameron acquisitions that resulted in a decrease in goodwill of $359,000. The Company revised its valuation of acquired deferred tax assets and property during the first quarter of 2012 as a result of information that existed at the acquisition date but was not available during the prior period. The error was identified in 2012 through the operation of the Company’s internal controls over financial reporting as it related to the Company’s acquisition accounting.

The Company performed the required annual impairment test of goodwill as of October 1, 2012. The Company’s annual impairment test did not indicate impairment at any of the Company’s reporting units as of the testing date, and subsequent to that date, management is not aware of any events or changes in circumstances since the impairment test that would indicate that goodwill might be impaired.

Prior to 2010, the Company recognized goodwill impairment of $9,681,000 at the Company’s LTC subsidiary based on a decrease in operating revenue and income, which resulted in the conclusion that the fair value of LTC may have been reduced below its carrying amount.

Title plant

The Company had title plant assets totaling $6,722,000 at December 31, 2012 and 2011, respectively. No events or changes in circumstances occurred during 2012 or 2011 to suggest the carrying value of the title plant was not recoverable.

Intangible assets subject to amortization

Definite-lived intangible assets had the following carrying values at December 31:

	2012							2011
(Dollars in thousands)	Gross Carrying Amount		Accumulated Amortization			Net Carrying Amount		Gross Carrying Amount		Accumulated Amortization			Net Carrying Amount
Core deposit intangibles	$	45,406	$	(26,284	)	$	19,122	$	45,406	$	(21,385	)	$	24,021
Customer relationship intangible asset		1,348		(410	)		938		1,348		(160	)		1,188
Total	$	46,754	$	(26,694	)	$	20,060	$	46,754	$	(21,545	)	$	25,209

The related amortization expense of purchase accounting intangible assets is as follows:

At December 31, 2012, the Company’s exposure to three investment security issuers individually exceeded 10% of shareholders’ equity:

(Dollars in thousands)	Amortized Cost		Market Value
Federal National Mortgage Association (Fannie Mae)	$	911,752	$	930,452
Government National Mortgage Association (Ginnie Mae)		205,389		209,692
Federal Home Loan Mortgage Corporation (Freddie Mac)		503,417		511,348
Total	$	1,620,558	$	1,651,492

Securities with carrying values of $1,712,860,000 and $1,698,943,000 were pledged to secure public deposits and other borrowings at December 31, 2012 and December 31, 2011, respectively.

Management evaluates securities for other-than-temporary impairment at least quarterly, and more frequently when economic or market concerns warrant such evaluation. Consideration is given to 1) the length of time and the extent to which the estimated fair value has been less than amortized cost, 2) the financial condition and near-term prospects of the issuer, and 3) the intent and ability of the Company to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in estimated fair value above amortized cost. In analyzing an issuer’s financial condition, management considers whether the securities are issued by the federal government or its agencies and whether downgrades by bond rating agencies have occurred, as well as review of issuer financial statements and industry analysts’ reports.

Information pertaining to securities with gross unrealized losses at December 31, 2012 and 2011 aggregated by investment category and length of time that individual securities have been in a continuous loss position, follows:

The Company assessed the nature of the losses in its portfolio as of December 31, 2012 and 2011 to determine if there are losses that are deemed other-than-temporary. In its analysis of these securities, management considered numerous factors to determine whether there were instances where the amortized cost basis of the debt securities would not be fully recoverable, including, but not limited to:

• the length of time and extent to which the estimated fair value of the securities was less than their amortized cost,

• whether adverse conditions were present in the operations, geographic area, or industry of the issuer,

• the payment structure of the security, including scheduled interest and principal payments, including the issuer’s failures to make scheduled payments, if any, and the likelihood of failure to make scheduled payments in the future,

• changes to the rating of the security by a rating agency, and

• subsequent recoveries or additional declines in fair value after the balance sheet date.

Management believes it has considered these factors, as well as all relevant information available, when determining the expected future cash flows of the securities in question. Except for the bond discussed below, in each instance, management has determined the cost basis of the securities would be fully recoverable. Management also has the intent and ability to hold debt securities until their maturity or anticipated recovery if the security is classified as available for sale. In addition, management does not believe the Company will be required to sell debt securities before the anticipated recovery of the amortized cost basis of the security.

At December 31, 2012, 49 debt securities had unrealized losses of 0.85% of the securities’ amortized cost basis and 0.12% of the Company’s total amortized cost basis. The unrealized losses for each of the 49 securities relate to market interest rate changes. Three of the 49 securities have been in a continuous loss position for over twelve months at December 31, 2012. These three securities had an aggregate amortized cost basis and unrealized loss of $5,200,000 and $187,000, respectively. Two of the three securities were issued by either the Federal National Mortgage Association (Fannie Mae), Federal Home Loan Mortgage Corporation (Freddie Mac), or the Government National Mortgage Association (Ginnie Mae). The Fannie Mae, Freddie Mac, and Ginnie Mae securities are rated AA+ by S&P and Aaa by Moodys. One of the securities in a continuous unrealized loss position for over twelve months was issued by a political subdivision and discussed in further detail below.

At December 31, 2011, 50 debt securities had unrealized losses of 0.5% of the securities’ amortized cost basis and 0.1% of the Company’s total amortized cost basis. The unrealized losses for each of the 50 securities relate to market interest rate changes. 12 of the 50 securities had been in a continuous loss position for over twelve months at December 31, 2011. These 12 securities had an aggregate amortized cost basis and unrealized loss of $24,453,000 and $391,000 respectively. The 12 securities were issued by either Federal National Mortgage Association (Fannie Mae), Federal Home Loan Mortgage Corporation (Freddie Mac) or by state and political subdivisions. The Fannie Mae and Freddie Mac securities were rated AA+ by S&P and Aaa by Moodys.

During 2011, management assessed the operating environment of a bond issuer as adverse and thus concluded that the Company had one unrated revenue municipal bond that warranted an other-than-temporary impairment charge during the year ended December 31, 2011. The specific impairment was related to the loss of the contracted revenue source required for bond repayment. The Company determined the impairment charge using observable market data for similar assets, including third party valuation of the security, as well as information from unobservable inputs, including its best estimate of the recoverability of the amortized cost of the security as outlined above. Changes to the unobservable inputs used by the Company would have resulted in a higher or lower impairment charge, but the unobservable inputs were not highly sensitive and would not result in a material difference in the impairment charge recorded for the year ended December 31, 2011. The impairment recorded in 2011 brought the total impairment to 50% of the par value of the bond and provided a fair value of the bonds that was consistent with current market pricing. Because adverse conditions were noted in the operations of the bond issuer, the Company recorded the other-than-temporary impairment. During the year ended December 31, 2012, the Company continued to analyze the operating environment of the bond as it did in 2011 and noted no further deterioration in the operating environment of the bond issuer.

The following table reflects activity during the years ended December 31, 2012, 2011, and 2010 related to credit losses on the other-than-temporarily impaired investment security where a portion of the unrealized loss was recognized in other comprehensive income.

As a result of the Company’s analysis, no other declines in the estimated fair value of the Company’s investment securities were deemed to be other-than-temporary at December 31, 2012 or December 31, 2011 except where noted above.

The amortized cost and estimated fair value by maturity of investment securities at December 31, 2012 are shown in the following table.

Acquisition And Disposition Activity

NOTE 4 – ACQUISITION AND DISPOSITION ACTIVITY

Acquisition of Florida Gulf Bancorp, Inc.

On July 31, 2012, the Company acquired Florida Gulf Bancorp, Inc. (“Florida Gulf”), the holding company of Florida Gulf Bank, headquartered in Fort Myers, Florida with 8 branches in the Fort Myers-Cape Coral, FL market. The Company acquired Florida Gulf in order to further expand its banking operations in the Fort Myers Metropolitan area. Under terms of the agreement, for each share of Florida Gulf stock outstanding, Florida Gulf shareholders received shares of the Company’s common stock equal to $23.00 and a cash payment for any fractional share. In addition, the agreement provides for potential additional cash consideration based on the resolution of certain identified loans over a three-year period after the acquisition. The Company acquired all of the outstanding common stock of the former Florida Gulf shareholders for total consideration of $45,339,000, which included the fair value of options granted and non-equity consideration paid, which resulted in goodwill of $32,420,000, as shown in the following table:

(Dollars in thousands)	Number of Shares		Amount
Equity Consideration
Common Stock issued		754,334	$	37,210
Options issued		32,863		651
Total Equity Consideration				37,861
Non-Equity Consideration
Change in Control Payments				1,342
Cash				4,625
Contingent Consideration				1,511
Total Non-Equity Consideration				7,478
Total Consideration Paid				45,339
Fair Value of Net Assets Assumed including Identifiable Intangible Assets				(12,919	)
Goodwill			$	32,420

The acquisition was accounted for under the purchase method of accounting in accordance with ASC Topic 805. Both the purchased assets and liabilities assumed were recorded at their respective acquisition date fair values. Identifiable intangible assets, including core deposit intangible assets, if any, were recorded at fair value. Because the consideration paid was greater than the net fair value of the acquired assets and liabilities, the Company recorded goodwill as part of the acquisition. The goodwill recognized was the result of the combined Companies’ expanded presence in the Fort Myers, Florida Metropolitan Statistical Area (“MSA”) through the addition of eight branches and an experienced in-market team that enhances the Company’s ability to compete in that market. Additionally, goodwill was also created by the expected cost savings that will be recognized in future periods through the elimination of redundant operations. Goodwill created in the acquisition in not deductible for income tax purposes.

In accordance with ASC Topic 805, estimated fair values are subject to change up to one year after the acquisition date. This allows for adjustments to the initial purchase entries if additional information relative to closing date fair values becomes available. Material adjustments to acquisition date estimated fair values would be recorded in the period in which the acquisition occurred, and as a result, previously reported results are subject to change. Information regarding the Company’s loan discount and related deferred tax asset, as well as income taxes payable and the related deferred tax balances, recorded in the acquisition may be adjusted as the Company refines its estimates of the current and deferred tax balances acquired, as well as the fair values of loans acquired and the deferred tax assets created from the acquisition. Determining the fair value of assets and liabilities, particularly illiquid assets and liabilities, is a complicated process involving significant judgment regarding estimates and assumptions used to calculate estimated fair value. The Company may incur losses on the acquired loans that are materially different from losses the Company originally projected. Fair value adjustments based on updated estimates could materially affect the goodwill recorded on the acquisition.

The acquired assets and liabilities, as well as the adjustments to record the assets and liabilities at their estimated fair values, are presented in the following table.

Explanation of Certain Fair Value Adjustments

(1) The adjustment represents the write down of the book value of Florida Gulf’s investments to their estimated fair value based on fair values on the date of acquisition.

(2) The adjustment represents the write down of the book value of Florida Gulf’s loans to their estimated fair value based on current interest rates and expected cash flows which includes estimates of expected credit losses inherent in the portfolio.

(3) The adjustment represents the write down of the book value of Florida Gulf’s OREO properties to their estimated fair value at the acquisition date based on their appraised value, as adjusted for costs to sell.

(4) The adjustment represents the deferred tax asset recognized on the fair value adjustments of Florida Gulf’s acquired assets and assumed liabilities.

(5) The adjustment represents the write down of the book value of Florida Gulf’s property, equipment, and other assets to their estimated fair value at the acquisition date based on their appraised value.

(6) The adjustment is necessary because the weighted average interest rate of Florida Gulf’s CDs exceeded the cost of similar funding at the time of acquisition. The fair value adjustment will be amortized to reduce interest expense over the life of the portfolio, which is estimated at 60 months.

(7) The adjustment is necessary because the interest rate of Florida Gulf’s fixed rate borrowings exceeded current interest rates on similar borrowings.

The Company’s consolidated financial statements as of and for the year ended December 31, 2012 include the operating results of the acquired assets and assumed liabilities for the 153 days subsequent to the July 31, 2012 acquisition date. Due to the system conversion of the acquired entity in August 2012 and subsequent integration of the operating activities of the acquired branches into existing Company markets, historical reporting for the former Florida Gulf branches is impracticable and thus disclosure of the revenue from the assets acquired and income before income taxes is impracticable for the 153-day period.

Supplemental pro forma information

The following pro forma information for the years ended December 31, 2012 and 2011 reflects the Company’s estimated consolidated results of operations as if the acquisition of Florida Gulf occurred at January 1, 2011, unadjusted for potential cost savings.

Acquisitions of OMNI BANCSHARES, Inc., Cameron Bancshares, Inc., and certain assets of Florida Trust Company

On May 31, 2011, the Company acquired OMNI BANCSHARES, Inc. (“OMNI”), the holding company of OMNI BANK, headquartered in Metairie, Louisiana with 14 offices in the New Orleans and Baton Rouge, LA markets. The Company acquired all of the outstanding common stock of the former OMNI shareholders for total consideration of $46,407,000, which resulted in goodwill of $63,756,000.

Also on May 31, 2011, the Company acquired Cameron Bancshares, Inc. (“Cameron”), the holding company of Cameron State Bank, headquartered in Lake Charles, Louisiana, with 22 offices and 48 ATMs in the Lake Charles region, in order to expand its banking operations into the Lake Charles, Louisiana area. The Company acquired all of the outstanding common stock of the former Cameron shareholders for total consideration of $143,241,000, which resulted in goodwill of $71,417,000.

On June 14, 2011, the Company purchased certain assets of the Florida Trust Company, a wholly-owned subsidiary of the Bank of Florida Corporation. Florida Trust Company operated offices in Naples and Ft. Lauderdale, Florida. Upon acquisition, the Florida Trust Company became part of the trust and asset management division of IBERIABANK. Under terms of the agreement, IBERIABANK paid the Bank of Florida Corporation $700,000 and a contingent payment of $670,000 for the acquisition of substantially all of the assets of Florida Trust Company. The acquisition resulted in additional intangible assets of $1,400,000 included in the Company’s consolidated balance sheet as of December 31, 2011, of which $52,000 was goodwill.

The acquisitions were accounted for under the purchase method of accounting in accordance with ASC Topic 805. Both the purchased assets and liabilities assumed were recorded at their respective acquisition date fair values. Identifiable intangible assets, including core deposit intangible assets, were recorded at fair value. Because the consideration paid was greater than the net fair value of the acquired assets and liabilities, the Company recorded goodwill as part of the acquisitions.

The acquired assets and liabilities are presented in the following table at fair value at each entity’s respective acquisition date. The table also includes intangible assets other than goodwill created in the acquisition, namely, core deposit intangible assets and a customer relationship intangible asset.

The unpaid principal balances of loans serviced for others were $257,883,000 and $198,860,000 at December 31, 2012 and 2011, respectively. Custodial escrow balances maintained in connection with the foregoing portfolio of loans serviced for others, and included in demand deposits, were immaterial at December 31, 2012 and 2011.

Mortgage Banking Activity

The Company through its subsidiary, IMC, originates mortgage loans for sale into the secondary market. The loans originated primarily consist of residential first mortgages that conform to standards established by the GSEs, but can also consist of junior lien loans secured by residential property. These sales are primarily to private companies that are unaffiliated with the GSEs on a servicing released basis. The following table details the mortgage banking activity as of and for the years ended December 31:

Loans Receivable

NOTE 6 – LOANS RECEIVABLE

Loans receivable at December 31, 2012 and December 31, 2011 consist of the following:

(Dollars in thousands)	2012		2011
Residential mortgage loans:
Residential 1-4 family	$	471,183	$	522,357
Construction/ Owner Occupied		6,021		16,143
Total residential mortgage loans		477,204		538,500
Commercial loans:
Real estate		3,631,543		3,363,891
Business		2,537,718		2,005,234
Total commercial loans		6,169,261		5,369,125

Home equity		1,251,125		1,019,110
Other		273,005		199,406
Total consumer and other loans		1,852,115		1,480,412
Total loans receivable	$	8,498,580	$	7,388,037

In 2009, the Company acquired substantially all of the assets and liabilities of CapitalSouth Bank (“CSB”), and certain assets and assumed certain deposit and other liabilities of Orion Bank (“Orion”) and Century Bank (“Century”). In 2010, the Company acquired certain assets and assumed certain deposit and other liabilities of Sterling Bank. The loans and foreclosed real estate that were acquired in these transactions are covered by loss share agreements between the FDIC and IBERIABANK, which afford IBERIABANK significant loss protection. Under the loss share agreements, the FDIC will cover 80% of covered loan and foreclosed real estate losses up to certain thresholds for all four acquisitions, 80% of losses that exceed the thresholds for Sterling Bank, and 95% of losses that exceed those thresholds for CSB, Orion, and Century only.

Because of the loss protection provided by the FDIC, the risks of the CSB, Orion, Century, and Sterling loans and foreclosed real estate are significantly different from those assets not covered under the loss share agreement. Accordingly, the Company presents loans subject to the loss share agreements as “covered loans” in the information below and loans that are not subject to the loss share agreement as “non-covered loans.”

Deferred loan origination fees were $14,040,000 and $9,422,000 and deferred loan expenses were $5,270,000 and $4,828,000 at December 31, 2012 and 2011, respectively. In addition to loans issued in the normal course of business, the Company considers overdrafts on customer deposit accounts to be loans and reclassifies these overdrafts as loans in its consolidated balance sheets. At December 31, 2012 and 2011, overdrafts of $3,231,000 and $1,646,000, respectively, have been reclassified to loans receivable.

Loans with carrying values of $1,504,512,000 and $1,112,214,000 were pledged to secure public deposits and other borrowings at December 31, 2012 and December 31, 2011, respectively.

Total consumer and other loans		1,674,417		1,282,965
Total non-covered loans receivable	$	7,405,824	$	6,053,588

The following tables provide an analysis of the aging of non-covered loans as of December 31, 2012 and 2011. Because of the difference in the accounting for acquired loans, the tables below further segregate the Company’s non-covered loans receivable between loans acquired from Florida Gulf in 2012, as well as those acquired in 2011, and loans originated by the Company. For purposes of the following tables, subprime mortgage loans are defined as the Company’s loans that have FICO scores that are less than 620 at the time of origination or were purchased outside of a business combination.

Covered Loans

The carrying amount of the acquired covered loans at December 31, 2012 and 2011 consisted of loans determined to be impaired at the time of acquisition, which are accounted for in accordance with ASC Topic 310-30, and loans that were considered to be performing at the acquisition date, accounted for by analogy to ASC Topic 310-30, as detailed in the following tables.

The Company has corrected its disclosure of historical covered loan balances by portfolio type for December 31, 2011 for the impact of an error in the allocation of loan discounts in its covered loan portfolio. The correction had no effect on the balance of total covered loans, total loans, total assets, or net income for the periods presented. The error was identified in 2012 through the operation of the Company’s internal controls over financial reporting as it related to the Company’s loan accounting. Using accounting guidance provided in ASC Topic 250, the Company assessed these items and determined the error, although immaterial to the consolidated financial statements for the year ended December 31, 2012, and immaterial to the overall financial statement presentation at December 31, 2011, would affect the comparability of the disclosures provided in these consolidated financial statements. As a result, the information included in these footnotes includes the effect this correction has on the previously reported disclosures for the December 31, 2011 period.

The following table presents the effect of this correction for the December 31, 2011 period.

The Company does not anticipate owing any consideration previously received under indemnification agreements to the FDIC under the “clawback” provisions of these agreements. Of the three agreements with the FDIC that contain clawback provisions, cumulative losses to date under two of these agreements have exceeded the calculated loss amounts which would result in clawback if not incurred. The sum of the historical and remaining projected losses under the remaining agreement is in excess of the clawback amount stated in that agreement.

Troubled Debt Restructurings

Information about the Company’s TDRs at December 31, 2012 and 2011 is presented in the following tables. The Company excludes as TDRs modifications of loans that are accounted for within a pool under Subtopic 310-30, which include the covered loans above, as well as the loans acquired in the OMNI and Cameron acquisitions completed during 2011 and those acquired from Florida Gulf in 2012. Accordingly, such modifications do not result in the removal of those loans from the pool, even if the modification of those loans would otherwise be considered a TDR. As a result, all covered loans and loans acquired from OMNI, Cameron, and Florida Gulf that would otherwise meet the criteria for classification as a troubled debt restructuring are excluded from the tables below.

Credit Quality

The Company’s investment in non-covered loans by credit quality indicator as of December 31, 2012 and 2011 is presented in the following tables. Because of the difference in the accounting for acquired loans, the tables below further segregate the Company’s non-covered loans receivable between loans acquired and loans that were not acquired. Loan discounts in the table below represent the adjustment of non-covered acquired loans to fair value at the time of acquisition, as adjusted for income accretion and changes in cash flow estimates in subsequent periods. Asset risk classifications for commercial loans reflect the classification as of December 31, 2012 and 2011.

Correction Of An Error In The Financial Statements

CORRECTION OF AN ERROR IN THE FINANCIAL STATEMENTS

The Company has corrected its historical consolidated statements of cash flows for the years ended December 31, 2011 and 2010 for the miscalculation of certain activity between its operating and investing cash flows. The correction did not have an effect on the Company’s consolidated balance sheets, statements of comprehensive income, or statements of shareholders’ equity for those years. The error was identified in 2012 through the operation of the Company’s internal controls over financial reporting. Using accounting guidance provided in Accounting Standards Codification (“ASC”) Topic 250, the Company assessed these items and determined the error would be considered material to the consolidated statements of cash flows for the years ended December 31, 2011 and 2010. The error also impacts the consolidated statements of cash flows for each quarter in 2012 and 2011 as described in Note 26. As a result, the information included in these consolidated financial statements and footnotes includes the effect this correction has on the previously reported financial statements for those years.

The following table presents the effect this correction has on the Consolidated Statements of Cash Flows for the years ended December 31, 2011 and 2010.

Use Of Estimates

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Material estimates that are susceptible to significant change in the near term are the allowance for credit losses, valuation of and accounting for loans covered by loss sharing arrangements with the FDIC and the related loss share receivable, valuation of and accounting for acquired loans, valuation of goodwill, intangible assets and other purchase accounting adjustments, and share-based compensation.

Concentration Of Credit Risks

CONCENTRATION OF CREDIT RISKS

Most of the Company’s business activity is with customers located within the States of Louisiana, Florida, Arkansas, Alabama, Texas, and Tennessee. The Company’s lending activity is concentrated in its market areas in those states. The Company has emphasized originations of commercial loans and private banking loans, defined as loans to larger consumer clients. Repayments on loans are expected to come from cash flows of the borrower and/or guarantor. Losses on secured loans are limited by the value of the collateral upon default of the borrowers. The Company does not have any significant concentrations to any one industry or customer.

Cash And Cash Equivalents

CASH AND CASH EQUIVALENTS

For purposes of presentation in the consolidated statements of cash flows, cash and cash equivalents are defined as cash, interest-bearing deposits and noninterest-bearing demand deposits at other financial institutions with original maturities less than three months. IBERIABANK may be required to maintain average balances on hand or with the Federal Reserve Bank to meet regulatory reserve and clearing requirements. At December 31, 2012 and 2011, the required reserve balances were $2,555,000 and $25,000, respectively. IBERIABANK had enough cash deposited with the Federal Reserve at December 31, 2012 and 2011 to cover the required reserve balance.

Investment Securities

INVESTMENT SECURITIES

Debt securities that management has the ability and intent to hold to maturity are classified as held to maturity and carried at cost, adjusted for amortization of premiums and accretion of discounts using methods approximating the interest method. Securities not classified as held to maturity or trading, including equity securities with readily determinable fair values, are classified as available for sale and recorded at fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive income. Declines in the value of individual held to maturity and available for sale securities below their cost that are other than temporary are included in earnings as realized losses. In estimating other than temporary impairment losses, management considers 1) the length of time and the extent to which the fair value has been less than cost, 2) the financial condition and near-term prospects of the issuer, 3) the intent and ability of the Company to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value, and 4) for debt securities, the recovery of contractual principal and interest. Gains or losses on securities sold are recorded on the trade date, using the specific identification method.

Loans Held For Sale

LOANS HELD FOR SALE

Mortgage loans originated and intended for sale in the secondary market are carried at the lower of cost or estimated fair value. Net unrealized losses, if any, are recognized through a valuation allowance that is recorded as a charge to income. Loans held for sale have primarily been fixed rate single-family residential mortgage loans under contract to be sold in the secondary market. In most cases, loans in this category are sold within thirty days. These loans are generally sold with the mortgage servicing rights released. Buyers generally have recourse to return a purchased loan to the Company under limited circumstances. Recourse conditions may include early payment default, breach of representations or warranties, and documentation deficiencies. During 2012 and 2011, an insignificant number of loans were returned to the Company.

Loans (Excluding Acquired Loans)

LOANS (EXCLUDING ACQUIRED LOANS)

The Company grants mortgage, commercial and consumer loans to customers. Except for loans acquired, loans receivable that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are stated at the unpaid principal balances, less the allowance for credit losses and net deferred loan origination fees and unearned discounts.

Interest income on loans is accrued over the term of the loans based on the principal balance outstanding. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield, using the effective interest method.

The accrual of interest on loans is discontinued at the time the loan is 90 days delinquent unless the credit is well-secured and in process of collection. Mortgage, credit card and other personal loans are typically charged down to net collateral value, less cost to sell, no later than 180 days past due. Past due status is based on the contractual terms of loans. In all cases, loans are placed on nonaccrual status or charged off at an earlier date if collection of principal or interest is considered doubtful.

The Company’s covered loan portfolio and non-covered loan portfolio, which are delineated between a) non-covered loans, excluding acquired loans, and b) acquired loans, are disaggregated into portfolio segments for purposes of determining the allowance for credit losses. The Company’s portfolio segments include commercial real estate, commercial business, mortgage, and consumer. The Company further disaggregates each commercial real estate, mortgage, and consumer portfolio segment into classes for purposes of monitoring and assessing credit quality based on certain risk characteristics. Classes within each commercial real estate portfolio segment include commercial real estate construction and commercial real estate – other. Classes within each mortgage portfolio segment include mortgage – prime and mortgage – subprime. Classes within each consumer portfolio segment include indirect auto, credit card, home equity, and consumer – other. Each commercial business portfolio segment is also considered a class.

Credit Quality

The Company utilizes an asset risk classification system in accordance with guidelines established by the Federal Reserve Board as part of its efforts to monitor commercial asset quality. “Special mention” loans are defined as loans where known information about possible credit problems of the borrower cause management to have some doubt as to the ability of these borrowers to comply with the present loan repayment terms and which may result in future disclosure of these loans as nonperforming. For assets with identified credit issues, the Company has two primary classifications for problem assets: “substandard” and “doubtful.” Substandard assets have one or more defined weaknesses and are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Doubtful assets have the weaknesses of substandard assets with the additional characteristic that the weaknesses make collection or liquidation in full satisfaction of the loan balance outstanding questionable and there is a high probability of loss based on currently existing facts, conditions and values. Loans classified as “Pass” do not meet the criteria set forth for special mention, substandard, or doubtful classification and are not considered criticized. Asset risk classifications are periodically reviewed and changed if, in the opinion of management, the risk profile of the customer has changed since the last review of the loan relationship.

A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. The impairment loss is measured on a loan by loan basis for commercial and construction loans by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral if the loan is collateral dependent.

In general, all interest accrued but not collected for loans that are placed on nonaccrual status or charged off is reversed against interest income. The interest on these loans is accounted for on the cash-basis method or cost-recovery method, until qualifying for a return to accrual status. Loans are returned to accrual status when all principal and interest amounts contractually due are brought current and future payments are reasonably assured.

Troubled Debt Restructurings

During the course of its lending operations, the Company periodically grants concessions to its customers in an attempt to protect as much of its investment as possible and minimize risk of loss. These concessions may include restructuring the terms of a customer loan to alleviate the burden of the customer’s near-term cash requirements. In order to be considered a troubled debt restructuring (“TDR”), the Company must conclude that the restructuring constitutes a concession and the customer is experiencing financial difficulties. The Company defines a concession to the customer as a modification of existing terms for economic or legal reasons that it would otherwise not consider. The concession is either granted through an agreement with the customer or is imposed by a court or law. Concessions include modifying original loan terms to reduce or defer cash payments required as part of the loan agreement, including but not limited to:

• a reduction of the stated interest rate for the remaining original life of the debt,

• extension of the maturity date or dates at a stated interest rate lower than the current market rate for new debt with similar risk characteristics,

• reduction of the face amount or maturity amount of the debt as stated in the agreement, or

• reduction of accrued interest receivable on the debt.

In its determination of whether the customer is experiencing financial difficulties, the Company considers numerous indicators, including, but not limited to:

• whether the customer is currently in default on its existing loan, or is in an economic position where it is probable the customer will be in default on its loan in the foreseeable future without a modification,

• whether the customer has declared or is in the process of declaring bankruptcy,

• whether there is substantial doubt about the customer’s ability to continue as a going concern,

• whether, based on its projections of the customer’s current capabilities, the Company believes the customer’s future cash flows will be insufficient to service the debt, including interest, in accordance with the contractual terms of the existing agreement for the foreseeable future, and

• whether, without modification, the customer cannot obtain sufficient funds from other sources at an effective interest rate equal to the current market rate for similar debt for a nontroubled debtor.

If the Company concludes that both a concession has been granted and the concession was granted to a customer experiencing financial difficulties, the Company identifies the loan as a TDR. For purposes of the determination of an allowance for credit losses for TDRs, the Company considers a loss probable on the loan, which is reviewed for specific impairment in accordance with the Company’s allowance for loan loss methodology. If it is determined that losses are probable on such TDRs, either because of delinquency or other credit quality indicator, the Company establishes specific reserves for these loans. For additional information on the Company’s allowance for credit losses, see Note 7 to these consolidated financial statements.

Acquired Loans And Related FDIC Loss Share Receivable

ACQUIRED LOANS AND RELATED FDIC LOSS SHARE RECEIVABLE

The Company accounts for its acquisitions under the purchase method, where all identifiable assets acquired, including loans, are recorded at fair value. No allowance for credit losses related to the acquired loans is recorded on the acquisition date as the fair value of the loans acquired incorporates assumptions regarding credit risk.

Loans acquired are recorded at fair value in accordance with the fair value methodology consistent with the exit price concept and exclusive of the shared-loss agreements with the FDIC from certain of the Company’s acquisitions in 2010 and 2009. The fair value estimates associated with the loans include estimates related to discount rates, expected prepayments and the amount and timing of undiscounted expected principal, interest and other cash flows. Credit discounts are included in the determination of fair value: therefore, an allowance for credit losses is not recorded at the acquisition date. At the time of acquisition, the Company estimated the fair value of the total acquired loan portfolio by segregating the total portfolio into loan pools with similar characteristics, which included:

• whether the loan was performing according to contractual terms at the time of acquisition,

• the loan type based on regulatory reporting guidelines, namely whether the loan was a mortgage, consumer, or commercial loan

• the nature of collateral,

• the interest rate type, whether fixed or variable rate, and

• the loan payment type, primarily whether the loan was amortizing or interest-only.

From these pools, the Company used certain loan information, including outstanding principal balance, estimated expected losses, weighted average maturity, weighted average term to re-price (if a variable rate loan), weighted average margin, and weighted average interest rate to estimate the expected cash flow for each loan pool.

Acquired loans are evaluated at acquisition and classified as purchase impaired or purchased non-impaired. Purchased impaired loans reflect credit deterioration since origination to the extent that it is probable at the time of acquisition that the Company will be unable to collect all contractually required payments. For purchased impaired loans, expected cash flows at the acquisition date in excess of the fair value of loans are recorded as interest income over the life of the loans using a level yield method if the timing and amount of future cash flows is reasonably estimable.

Subsequent to acquisition, the Company performs cash flow re-estimations at least quarterly for each purchased impaired loan and/or loan pool. Increases in estimated cash flows above those expected at acquisition are recognized on a prospective basis as interest income over the remaining life of the pool. Decreases in expected cash flows subsequent to acquisition result in recognition of a provision for credit loss.

Acquired loans are placed on nonaccrual status when the Company cannot reasonably estimate cash flows on a loan or loan pool.

Pursuant to an AICPA letter dated December 18, 2009, the AICPA summarized the SEC staff’s view regarding the accounting in subsequent periods for discount accretion associated with loan receivables acquired in a business combination or asset purchase. Regarding the accounting for such loan receivables that, in the absence of further standard setting, the AICPA understands the SEC staff would not object to an accounting policy based on contractual cash flows (ASC Topic 310-20 approach) or an accounting policy based on expected cash flows (ASC 310-30 approach). The Company believes analogizing to ASC Topic 310-30 is the more appropriate option to follow in accounting for the fair value discount. However, in cases where a loan is acquired at a premium or slight discount, the Company believes that the contractual yield approach outlined in ASC Topic 310-20 is the more appropriate approach to apply.

FDIC loss share receivable

Because the FDIC will reimburse the Company for certain loans acquired in 2009 and 2010 should the Company experience a loss, an indemnification asset is recorded at fair value at the acquisition date. The indemnification asset is recognized at the same time as the indemnified loans, and measured on the same basis, subject to collectability or contractual limitations. The shared loss agreements on the acquisition date reflect the reimbursements expected to be received from the FDIC, using an appropriate discount rate, which reflects counterparty credit risk and other uncertainties.

The shared loss agreements continue to be measured on the same basis as the related indemnified loans, and the loss share receivable is impacted by changes in estimated cash flows associated with these loans. Deterioration in the credit quality of the acquired loans and related expected cash flows (immediately recorded as an adjustment to the allowance for credit losses) would immediately increase the loss share receivable, with the offset recorded through the consolidated statement of income. Increases in the credit quality of the acquired loans and related cash flows (reflected as an adjustment to yield and accreted into income over the remaining life of the loans) decrease the basis of the shared loss agreements, with such decrease being amortized into income over 1) the life of the loan or 2) the life of the shared loss agreements, whichever is shorter. Loss assumptions used to measure the basis of the indemnified loans are consistent with the loss assumptions used to measure the indemnification asset. Fair value accounting incorporates into the fair value of the indemnification asset an element of the time value of money, which is accreted back into income over the life of the shared loss agreements.

Upon the collection from the FDIC of an incurred loss the indemnification asset will be reduced by the amount owed by the FDIC. A corresponding claim receivable is established when a loss is incurred and recorded in other assets until cash is received from the FDIC.

For further discussion of the Company’s acquisitions and loan accounting, see Note 4 and Note 6 to the consolidated financial statements.

Allowance For Credit Losses

ALLOWANCE FOR CREDIT LOSSES

The allowance for credit losses represents management’s best estimate of probable credit losses inherent in the loan portfolios and off-balance sheet lending commitments at the balance-sheet date. The allowance for credit losses is maintained at a level the Company considers appropriate and is based on quarterly assessments and evaluations of the collectability and historical loss experience, including both industry and Company specific considerations. While management uses the best information available to establish the allowance for credit losses, future adjustments may be necessary if economic conditions differ substantially from the assumptions used in determining the allowance or, if required by regulators, based upon information available to them at the time of their examinations, or if mandated by revisions to, new interpretations of, or issuance of new accounting standards. See Note 7 for an analysis of the Company’s allowance for credit losses by portfolio and portfolio segment, and credit quality information by class. The entire amount of the allowance for credit losses is available to absorb losses on any category or lending-related commitment for non-acquired loans. The allowance related to acquired loans represents management’s best estimate of cumulative impairment as described further in “Purchase Impaired Loans (Acquired Loans)”.

The Company’s strategy for credit risk management includes a combination of conservative exposure limits, which are significantly below legal lending limits and conservative underwriting, documentation and collection standards. The strategy emphasizes geographic, industry, and customer diversification within the Company’s operating footprint, regular credit examinations, and regular management reviews of large credit exposures and loans experiencing credit quality deterioration.

The Company has not substantively changed any material aspect in its overall approach of determining the current year allowance for credit losses. There have been no material changes in criteria or estimation techniques as compared to prior periods that impacted the determination of the current allowance for credit losses.

Allowance for credit losses discussion below includes discussion specific to loans accounted for under the contractual yield method, referred to as “contractual loans”, and loans accounted for as acquired credit impaired loans.

Contractual Loans (Excluding Acquired Loans)

Contractual loans represent loans accounted for under the contractual yield method. The Company’s contractual loans include loans originated by the Company and acquired loans that are not accounted for as acquired credit impaired loans, typically referred to as legacy loans. Credit losses on contractual loans are charged and recoveries are credited to the allowance for credit losses. Provisions for loan losses are based on the Company’s review of historical industry and Company specific loss experience, and factors that management determines should be considered in estimating probable credit losses.

Loans identified as impaired are subject to individual quarterly review for potential loss. The Company considers the current value of collateral, credit quality of any guarantees, the guarantor’s liquidity and willingness to cooperate, and other factors when evaluating whether an individual loan is impaired. Other factors may include the industry and geographic location of the borrower, size and financial condition of the borrower, cash flow and leverage of the borrower, and evaluation of the borrower’s management. When individual loans are impaired, allowances are estimated based on management’s assessment of the borrower’s ability to repay the loan given the availability of collateral and other sources of cash flow, including evaluation of available legal options. Allowances for individually impaired loans are estimated based on the present value of expected future cash flows discounted at the loan’s effective interest rate, fair value of the underlying collateral or readily observable secondary market values. Collectability of principal and interest is evaluated in assessing the need for a loss accrual.

The Company also estimates reserves for collective impairment that reflect an estimated measurement of losses related to loans not subject to individual review as of the balance sheet date. Such loans are grouped in homogenous pools or segments, which are consistent with the segments and classes described above. Embedded loss rates are derived from migration analyses, which track net charge-off experience sustained on loans according to their risk grade, and may be adjusted for Company-specific and/or industry factors. Loss rates are reviewed quarterly and adjusted as management deems necessary based on changing borrower and/or collateral conditions and actual collections and charge-off experience.

Based on observations made through a qualitative review, management may apply qualitative adjustments to the quantitatively determined loss estimates at a pool and/or portfolio segment level as deemed appropriate. Primary qualitative and environmental factors that may not be directly reflected in quantitative estimates include:

• asset quality trends,

• changes in lending and risk management practices and procedures

• trends in the nature and volume of the loan portfolio, including the existence and effect of any portfolio concentrations

• changes in experience and depth of lending staff

• legal, regulatory and competitive environment

• national and regional economic trends

• data availability and applicability

Changes in these factors are considered in determining the directional consistency of changes in the allowance for credit losses. The impact of these factors on the Company’s qualitative assessment of the allowance for credit losses can change from period to period based on management’s assessment of the extent to which these factors are already reflected in historic loss rates. The uncertainty inherent in the estimation process is also considered in evaluating the allowance for credit losses.

Purchased Impaired Loans (Acquired Loans)

Purchased impaired loans represent loans acquired by the Company, which are accounted in accordance with ASC 310-30. Credit losses incurred subsequent to acquisition are charged to the allowance for credit losses. Recoveries are credited to the allowance for credit losses to the extent the losses were incurred subsequent to acquisition. Recoveries related to credit losses incurred prior to acquisition are reflected as prospective adjustments to yield, which are accreted to income over the remaining life of the associated pool of loans. Provisions for credit losses are based on the Company’s determination of the timing and amount of expected cash flows. Provisions for credit losses associated with loans covered by loss share agreements with the FDIC are partially offset by increases in the FDIC loss share receivable.

The allowance for credit losses related to loans accounted for as purchased impaired loans is based on management’s re-estimation of expected cash flows for each loan pool. An allowance for credit losses is established to the extent that the expected cash flows of a loan pool have decreased since acquisition.

Off-Balance Sheet Credit Related Financial Instruments

OFF-BALANCE SHEET CREDIT RELATED FINANCIAL INSTRUMENTS

The Company accounts for its guarantees in accordance with the provisions of ASC Topic 460. In the ordinary course of business, the Company has entered into commitments to extend credit, including commitments under credit card arrangements, commercial letters of credit and standby letters of credit. Such financial instruments are recorded when they are funded.

Derivative Financial Instruments

DERIVATIVE FINANCIAL INSTRUMENTS

ASC Topic 815 requires that all derivatives be recognized as assets or liabilities in the balance sheet at fair value. The Company may enter into derivative contracts to manage exposure to interest rate risk or to meet the financing and/or investing needs of its customers.

In the course of its business operations, the Company is exposed to certain risks, including interest rate, liquidity, and credit risk. The Company manages its risks through the use of derivative financial instruments, primarily through management of exposure due to the receipt or payment of future cash amounts based on interest rates. The Company’s derivative financial instruments manage the differences in the timing, amount, and duration of expected cash receipts and payments.

The primary types of derivatives used by the Company include interest rate swap agreements, forward sales contracts, interest rate lock commitments, and written and purchased options.

Hedging Activities

As part of its activities to manage interest rate risk due to interest rate movements, the Company has engaged in interest rate swap transactions to manage exposure to interest rate risk through modification of the Company’s net interest sensitivity to levels deemed to be appropriate. The Company utilizes these interest rate swap agreements to convert a portion of its variable-rate debt to a fixed rate (cash flow hedge). Interest rate swaps are contracts in which a series of interest rate flows are exchanged over a prescribed period. The notional amount on which the interest payments are based is not exchanged.

Because the swap agreements used to manage interest rate risk have been designated as hedging exposure to variable cash flows of a forecasted transaction, the effective portion of the derivative’s gain or loss is initially reported as a component of other comprehensive income and subsequently reclassified into earnings when the forecasted transaction affects earnings or when the hedge is terminated. The ineffective portion of the gain or loss is reported in earnings immediately.

In applying hedge accounting for derivatives, the Company establishes a method for assessing the effectiveness of the hedging derivative and a measurement approach for determining the ineffective aspect of the hedge upon the inception of the hedge. These methods are consistent with the Company’s approach to managing risk.

Other Derivative Instruments

Interest rate swap agreements

In addition to using derivative instruments as an interest rate risk management tool, the Company also enters into derivative instruments to help its commercial customers manage their exposure to interest rate fluctuations. To mitigate the interest rate risk associated with these customer contracts, the Company enters into offsetting derivative contract positions. The Company manages its credit risk, or potential risk of default by its commercial customers, through credit limit approval and monitoring procedures.

For interest rate swap agreements that are not designated as hedging instruments, changes in the fair value of the derivatives are recognized in earnings immediately.

Rate lock commitments

The Company enters into commitments to originate loans intended for sale whereby the interest rate on the prospective loan is determined prior to funding (“rate lock commitments”). A rate lock is given to a borrower, subject to conditional performance obligations, for a specified period of time that typically does not exceed 60 days. Simultaneously with the issuance of the rate lock to the borrower, a rate lock is received from an investor for a best efforts or mandatory delivery of the loan. Under the terms of the best efforts delivery lock, the investor commits to purchase the loan at a specified price, provided the loan is funded and delivered prior to a specified date and provided that the credit and loan characteristics meet pre-established criteria for such loans. Rate lock commitments on mortgage loans that are intended to be sold are considered to be derivatives. Accordingly, such commitments are recorded at fair value as derivative assets or liabilities, with changes in fair value recorded in mortgage income.

Equity-indexed certificates of deposit

IBERIABANK offers its customers a certificate of deposit that provides the purchaser a guaranteed return of principal at maturity plus potential return, which allows IBERIABANK to identify a known cost of funds. The rate of return is based on the performance of a basket of publically traded stocks that represent a variety of industry segments. Because it is based on an equity index, the rate of return represents an embedded derivative that is not clearly and closely related to the host instrument and is to be accounted for separately. Accordingly, the certificate of deposit is separated into two components: a zero coupon certificate of deposit (the host instrument) and a written option purchased by the depositor (an embedded derivative). The discount on the zero coupon deposit is amortized over the life of the deposit, and the written option is carried at fair value on the Company’s consolidated balance sheet, with changes in fair value recorded through earnings. IBERIABANK offsets the risks of the written option by purchasing an option with terms that mirror the written option and that is also carried at fair value on the Company’s consolidated balance sheet.

Premises And Equipment

PREMISES AND EQUIPMENT

Land is carried at cost. Buildings, furniture, fixtures, and equipment are carried at cost, less accumulated depreciation computed on a straight line basis over the estimated useful lives of 10 to 40 years for buildings and 3 to 15 years for furniture, fixtures and equipment. Capitalized leasehold improvements are amortized over the length of the initial lease agreement or their useful life, whichever is shorter.

Other Real Estate

OTHER REAL ESTATE

Other real estate includes all real estate, other than bank premises used in bank operations, owned or controlled by the Company, including real estate acquired in settlement of loans. Properties are recorded at the balance of the loan (which is the pro-rata carrying value of loans accounted for in accordance with ASC 310-30) or at estimated fair value less estimated selling costs, whichever is less, at the date acquired. Subsequent to foreclosure, management periodically performs valuations and the assets are carried at the lower of cost or fair value less estimated selling costs. Revenue and expenses from operations, gain or loss on sale and changes in the valuation allowance are included in net expenses from foreclosed assets.

For further discussion of the Company’s other real estate owned, see Note 11 to the consolidated financial statements.

Goodwill And Other Intangible Assets

GOODWILL AND OTHER INTANGIBLE ASSETS

Goodwill

Goodwill is accounted for in accordance with ASC Topic 350, and accordingly is not amortized but is evaluated at least annually for impairment. As part of its testing, the Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the Company determines the fair value of a reporting unit is less than its carrying amount using these qualitative factors, the Company compares the fair value of goodwill with its carrying amount, and then measures impairment loss by comparing the implied fair value of goodwill with the carrying amount of that goodwill.

Title Plant

The Company records its title plant assets in accordance with ASC Topic 950. Under ASC Topic 950, costs incurred to construct a title plant, including the costs incurred to obtain, organize, and summarize historical information, are capitalized until the title plant can be used to perform title searches. Purchased title plant, including a purchased undivided interest in title plant, is recorded at cost at the date of acquisition. For title plant acquired separately or as part of a company acquisition, cost is measured as the fair value of the consideration given. Capitalized costs of title plant are not depreciated or charged to income unless circumstances indicate that the carrying amount of the title plant has been impaired. Impairment identifiers include a change in legal requirements or statutory practices, identification of obsolescence, and abandonment of the title plant, among other identifiers.

Intangible assets subject to amortization

The Company’s acquired intangible assets that are subject to amortization include core deposit intangibles, amortized on a straight line or accelerated basis over a 10 year average life and a customer relationship intangible asset, amortized on an accelerated basis over a 9.5 year life.

Transfers Of Financial Assets

TRANSFERS OF FINANCIAL ASSETS

Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when 1) the assets have been isolated from the Company, 2) the transferee obtains the right, free of conditions that constrain it from taking advantage of that right, to pledge or exchange the transferred assets, and 3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Should the transfer not meet these three criteria, the transaction is treated as a secured financing.

Income Taxes

INCOME TAXES

The Company and all subsidiaries file a consolidated federal income tax return on a calendar year basis. The Company files income tax returns in the U.S. federal jurisdiction and various state jurisdictions through IBERIABANK, LTC and their subsidiaries. In lieu of Louisiana state income tax, IBERIABANK is subject to the Louisiana bank shares tax, which is included in noninterest expense or income tax expense in the Company’s consolidated financial statements. With few exceptions, the Company is no longer subject to U.S. federal, state or local income tax examinations for years before 2009.

Deferred income tax assets and liabilities are determined using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is determined based on the tax effects of the temporary differences between the book and tax bases of the various balance sheet assets and liabilities and gives current recognition to changes in tax rates and laws. The measurement of deferred tax assets is reduced, if necessary, by the amount of any tax benefits that, based on available evidence, are not expected to be realized.

The Company recognizes interest and penalties accrued related to unrecognized tax benefits, if applicable, in noninterest expense.

Stock Compensation Plans

STOCK COMPENSATION PLANS

The Company issues stock options and restricted stock under various plans to directors, officers and other key employees. The Company accounts for its stock compensation plans in accordance with ASC Topics 718 and 505. Under those provisions, the Company has adopted a fair value based method of accounting for employee stock compensation plans, whereby compensation cost is measured at the grant date based on the value of the award and is recognized on a straight-line basis over the service period, which is usually the vesting period, taking into account retirement eligibility. As a result, compensation expense relating to stock options and restricted stock is reflected in net income as part of “Salaries and employee benefits” on the consolidated statements of income. The Company’s practice has been to grant options at no less than the fair market value of the stock at the grant date.

See Note 19 for additional information on the Company’s share-based compensation plans.

Earnings Per Common Share

EARNINGS PER COMMON SHARE

Basic earnings per share represents income available to common shareholders divided by the weighted average number of common shares outstanding during the period. Diluted earnings per share reflect additional common shares that would have been outstanding if dilutive potential common shares, in the form of stock options, had been issued, as well as any adjustment to income that would result from the assumed issuance. Participating common shares issued by the Company relate to unvested outstanding restricted stock awards, the earnings allocated to which are used in determining income available to common shareholders under the two-class method.

See Note 3 for additional information on the Company’s calculation of earnings per share.

Treasury Stock

TREASURY STOCK

The purchase of the Company’s common stock is recorded at cost. At the date of retirement or subsequent reissuance, treasury stock is reduced by the cost of such stock with differences recorded in additional paid-in capital or retained earnings, as applicable.

Comprehensive Income

COMPREHENSIVE INCOME

Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income. Although certain changes in assets and liabilities, such as unrealized gains and losses on available for sale securities and cash flow hedges, are reported as a separate component of the equity section of the balance sheet, such items, along with net income, are components of comprehensive income.

Segments

SEGMENTS

All of the Company’s banking operations are considered by management to be aggregated in one reportable operating segment. Because the overall banking operations comprise substantially all of the consolidated operations and none of the Company’s other subsidiaries, either individually or in the aggregate, meet quantitative materiality thresholds, no separate segment disclosures are presented in these consolidated financial statements. The Company has invested in its financial reporting infrastructure to report financial information associated with performance of lines of business within the banking operating segment. The Company anticipates reporting this information sometime in 2013.

Fair Value Measurements

FAIR VALUE MEASUREMENTS

The Company estimates fair value based on the assumptions market participants would use when selling an asset or transferring a liability and characterizes such measurements within the fair value hierarchy based on the inputs used to develop those assumptions and measure fair value. The hierarchy requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows:

• Level 1 – Quoted prices in active markets for identical assets or liabilities.

• Level 2 – Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

• Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs.

A description of the valuation methodologies used for instruments measured at fair value follows, as well as the classification of such instruments within the valuation hierarchy.

Securities available for sale

Securities are classified within Level 1 where quoted market prices are available in an active market. Inputs include securities that have quoted prices in active markets for identical assets. If quoted market prices are unavailable, fair value is estimated using quoted prices of securities with similar characteristics, at which point the securities would be classified within Level 2 of the hierarchy. Examples may include certain collateralized mortgage and debt obligations.

Mortgage loans held for sale

As of December 31, 2012, the Company has $267,475,000 of conforming mortgage loans held for sale. Mortgage loans originated and held for sale are carried at the lower of cost or estimated fair value. The Company obtains quotes or bids on these loans directly from purchasing financial institutions. Mortgage loans held for sale that were recorded at estimated fair value are included in the table in Note 22.

Impaired loans

Loans are measured for impairment using the methods permitted by ASC Topic 310. Fair value measurements are used in determining impairment using either the loan’s obtainable market price, if available (Level 1) or the fair value of the collateral if the loan is collateral dependent (Level 2). Measuring the impairment of loans using the present value of expected future cash flows, discounted at the loan’s effective interest rate, is not considered a fair value measurement. Fair value of the collateral is determined by appraisals or independent valuation.

Other real estate owned

Fair values of OREO at December 31, 2012 are determined by sales agreement or appraisal, and costs to sell are based on estimation per the terms and conditions of the sales agreement or amounts commonly used in real estate transactions. Inputs include appraisal values on the properties or recent sales activity for similar assets in the property’s market, and thus OREO measured at fair value would be classified within Level 2 of the hierarchy. The Company included property write-downs of $6,409,000, $7,250,000, and $2,943,000 in earnings for the years ended December 31, 2012, 2011, and 2010, respectively.

Derivative financial instruments

The Company utilizes interest rate swap agreements to convert a portion of its variable-rate debt to a fixed rate (cash flow hedge). The Company also enters into commitments to originate loans whereby the interest rate on the prospective loan is determined prior to funding (“rate lock commitments”). Rate lock commitments on mortgage loans that are intended to be sold are considered to be derivatives. The Company offers its customers a certificate of deposit that provides the purchaser a guaranteed return of principal at maturity plus potential return, which allows the Company to identify a known cost of funds. The rate of return is based on an equity index, and as such represents an embedded derivative. Fair value of interest rate swaps, interest rate lock commitments, and equity-linked written and purchased options are estimated using prices of financial instruments with similar characteristics, and thus are classified within Level 2 of the fair value hierarchy.

FHLB advance repayments are amortized over periods ranging from two to 30 years, and have a balloon feature at maturity. Advances are collateralized by a blanket pledge of eligible loans, subject to contractual adjustments which reduce the borrowing base, as well as a secondary pledge of FHLB stock and FHLB demand deposits. Total additional advances available from the FHLB at December 31, 2012 were $1,350,424,000 under the blanket floating lien and an additional $79,539,000 with a pledge of investment securities. The weighted average advance rate at December 31, 2012 was 4.31%.

The Company has various funding arrangements with commercial banks providing up to $130,000,000 in the form of federal funds and other lines of credit. At December 31, 2012, there were no balances outstanding on these lines and all of the funding was available to the Company.

Junior subordinated debt consists of a total of $111,862,000 in Junior Subordinated Deferrable Interest Debentures of the Company issued to statutory trusts that were funded by the issuance of floating rate capital securities of the trusts. Issuances of $10,310,000 each were completed in November 2002, June 2003, September 2004, and June 2007 and an issuance of $15,464,000 was completed in October 2006. The issue of $6,186,000 completed in March 2003 was assumed in the American Horizons acquisition. The Company issued $25,775,000 in November 2007 and $7,217,000 in March 2008 to provide funding for various business activities, primarily loan growth. Issuances of $8,248,000 and $7,732,000 were assumed in the OMNI acquisition during 2011.

The term of the securities is 30 years, and they are callable at par by the Company anytime after 5 years. Interest is payable quarterly and may be deferred at any time at the election of the Company for up to 20 consecutive quarterly periods. During a deferral period, the Company is subject to certain restrictions, including being prohibited from declaring and paying dividends to its common shareholders.

The debentures qualify as Tier 1 Capital and the capital note qualifies as Tier 2 capital for regulatory purposes.

Share-Based Compensation

NOTE 19 – SHARE-BASED COMPENSATION

The Company has various types of share-based compensation plans. These plans are administered by the Compensation Committee of the Board of Directors, which selects persons eligible to receive awards and determines the number of shares and/or options subject to each award, the terms, conditions and other provisions of the awards. During the years ended December 31, 2012, 2011, and 2010, the Company did not have any equity awards that were settled in cash.

Stock option plans

The Company issues stock options under various plans to directors, officers and other key employees. The option exercise price cannot be less than the fair value of the underlying common stock as of the date of the option grant and the maximum option term cannot exceed ten years. The stock options granted were issued with vesting periods ranging from one-and-a half to seven years. At December 31, 2012, future option or restricted stock awards of 688,943 shares could be made under approved incentive compensation plans.

The following table represents the compensation expense that is included in salaries and employee benefits expense and related income tax benefits in the accompanying consolidated statements of comprehensive income related to stock options for the years indicated below.

(Dollars in thousands, except per share data)	2012		2011		2010
Compensation expense related to stock options	$	1,873	$	1,343	$	1,301
Income tax benefit related to stock options		656		470		455
Impact on basic earnings per share		0.04		0.03		0.03
Impact on diluted earnings per share		0.04		0.03		0.03

The Company reported $1,221,000, $1,454,000 and $637,000 of excess tax benefits as financing cash inflows during the years ended December 31, 2012, 2011, and 2010, respectively, related to the exercise and vesting of stock options. Net cash proceeds from the exercise of stock options were $2,813,000, $6,807,000 and $1,631,000 for the years ended December 31, 2012, 2011, and 2010, respectively.

The Company uses the Black-Scholes option pricing model to estimate the fair value of share-based awards. The following weighted-average assumptions were used for option awards granted during the years ended December 31^st of the periods indicated:

	2012			2011			2010
Expected dividends		2.7	%		2.4	%		2.3	%
Expected volatility		40.1	%		35.5	%		39.3	%
Risk-free interest rate		0.8	%		1.5	%		2.3	%
Expected term (in years)		5.0			4.0			5.0
Weighted-average grant-date fair value	$	14.50		$	12.83		$	18.11

The assumptions above are based on multiple factors, including historical stock option exercise patterns and post-vesting employment termination behaviors, expected future exercise patterns and the expected volatility of the Company’s stock price.

At December 31, 2012, there was $5,174,000 of unrecognized compensation cost related to stock options which is expected to be recognized over a weighted-average period of 4.7 years.

The following table represents the activity related to stock options during the periods indicated.

At December 31, 2012, the aggregate intrinsic value of shares underlying outstanding stock options and underlying exercisable stock options was $2,647,000 and $2,600,000. Total intrinsic value of options exercised was $1,765,000, $6,783,000 and $2,314,000 for the years ended December 31, 2012, 2011, and 2010, respectively.

Restricted stock plans

The Company issues restricted stock under various plans for certain officers and directors. A supplemental stock benefit plan adopted in 1999 and the 2001, 2005, 2008, and 2010 Incentive Plans allow grants of restricted stock. The plans allow for the issuance of restricted stock awards that may not be sold or otherwise transferred until certain restrictions have lapsed. The holders of the restricted stock receive dividends and have the right to vote the shares. The fair value of the restricted stock shares awarded under these plans is recorded as unearned share-based compensation, a contra-equity account. The unearned compensation related to these awards is amortized to compensation expense over the vesting period (generally three to seven years). The total share-based compensation expense for these awards is determined based on the market price of the Company’s common stock at the date of grant applied to the total number of shares granted and is amortized over the vesting period. As of December 31, 2012, unearned share-based compensation associated with these awards totaled $22,421,000.

The following table represents the compensation expense that was included in salaries and employee benefits expense in the accompanying consolidated statements of income related to restricted stock grants for the years ended December 31:

Phantom stock awards

As part of the 2008 Incentive Compensation Plan and 2009 Phantom Stock Plan, the Company issues phantom stock awards to certain key officers and employees. The award is subject to a vesting period of five to seven years and is paid out in cash upon vesting. The amount paid per vesting period is calculated as the number of vested “share equivalents” multiplied by the closing market price of a share of the Company’s common stock on the vesting date. Share equivalents are calculated on the date of grant as the total award’s dollar value divided by the closing market price of a share of the Company’s common stock on the grant date. Award recipients are also entitled to a “dividend equivalent” on each unvested share equivalent held by the award recipient. A dividend equivalent is a dollar amount equal to the cash dividends that the participant would have been entitled to receive if the participant’s share equivalents were issued in shares of common stock. Dividend equivalents will be deemed to be reinvested as share equivalents that will vest and be paid out on the same date as the underlying share equivalents on which the dividend equivalents were paid. The number of share equivalents acquired with a dividend equivalent is determined by dividing the aggregate of dividend equivalents paid on the unvested share equivalents by the closing price of a share of the Company’s common stock on the dividend payment date.

The following table represents phantom stock award activity during the periods indicated. During the years ended December 31, 2012, 2011, and 2010, the Company recorded $2,185,000, $1,368,000 and $381,000, respectively, in compensation expense based on the number of share equivalents vested at the end of the period and the current market price of the Company’s stock.

Balance, December 31, 2012		318,729			16,035			334,764		$	16,444,000

(1) Except for vested share payments, which are based on the cash paid at the time of vesting, the value of share equivalents is calculated based on the market price of the Company’s stock at the end of the respective periods. The market price of the Company’s stock was $49.12, $49.30, and $59.13 on December 31, 2012, 2011, and 2010, respectively.

401(k) profit sharing plan

The Company has a 401(k) Profit Sharing Plan covering substantially all of its employees. Annual employer contributions to the plan are set by the Board of Directors.

Earnings Per Share

Earnings Per Share

NOTE 3 – EARNINGS PER SHARE

Share-based payment awards that entitle holders to receive non-forfeitable dividends before vesting are considered participating securities and thus included in the calculation of basic earnings per share. These awards are included in the calculation of basic earnings per share under the two-class method. The two-class method allocates earnings for the period between common shareholders and other security holders. The participating awards receiving dividends will be allocated the same amount of income as if they were outstanding shares.

The following table presents the calculation of basic and diluted earnings per share for the years ended December 31, 2012, 2011, and 2010.

	For the Years Ended December 31,
(Dollars in thousands, except per share data)	2012			2011			2010
Income available to common shareholders	$	76,395		$	53,538		$	48,826

Weighted average shares outstanding - Diluted		28,957,696			28,141,300			25,394,120
Earnings per common share - Basic	$	2.59		$	1.88		$	1.90
Earnings per common share - Diluted	$	2.59		$	1.87		$	1.88
Earnings per unvested restricted stock share - Basic	$	2.61		$	2.04		$	1.97
Earnings per unvested restricted stock share - Diluted	$	2.60		$	2.00		$	1.95

(1) Weighted average basic shares outstanding include 552,609, 484,361, and 498,692 shares of unvested restricted stock for the years ended December 31, 2012, 2011, and 2010, respectively.

Additional information on the Company’s basic earnings per common share is shown in the following table.

	For the Years Ended December 31,
(Dollars in thousands, except per share data)	2012		2011		2010
Distributed earnings to common shareholders	$	39,349	$	38,681	$	35,772

Distributed earnings to unvested restricted stock	$	758	$	727	$	733
Undistributed earnings to unvested restricted stock		685		261		248
Total earnings allocated to restricted stock	$	1,443	$	988	$	981
Distributed earnings per common share	$	1.36	$	1.38	$	1.42
Undistributed earnings per common share		1.23		.50		.48
Total earnings per common share - Basic	$	2.59	$	1.88	$	1.90
Distributed earnings per unvested restricted stock share	$	1.37	$	1.50	$	1.47
Undistributed earnings per unvested restricted stock share		1.24		0.54		0.50
Total earnings per unvested restricted stock share - Basic	$	2.61	$	2.04	$	1.97

For the years ended December 31, 2012, 2011, and 2010, the calculations for basic shares outstanding exclude: (1) the weighted average shares owned by the Recognition and Retention Plan (“RRP”) of 612,097, 571,262 and 560,767, respectively, and (2) the weighted average shares in treasury stock of 1,964,825, 1,300,222, and 1,256,418, respectively.

The effect from the assumed exercise of 752,188, 542,716, and 477,665 stock options was not included in the computation of diluted earnings per share for years ended December 31, 2012, 2011, and 2010, respectively, because such amounts would have had an antidilutive effect on earnings per share.

Commitments And Contingencies

Commitments And Contingencies

NOTE 20 – COMMITMENTS AND CONTINGENCIES

Off-balance sheet commitments

The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. Such commitments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated balance sheets. The same credit policies are used in these commitments as for on-balance sheet instruments. The Company’s exposure to credit loss in the event of nonperformance by the other parties is represented by the contractual amount of the financial instruments. At December 31, 2012, the fair value of guarantees under commercial and standby letters of credit was $622,000. This amount represents the unamortized fee associated with these guarantees and is included in the consolidated balance sheet of the Company. This fair value will decrease over time as the existing commercial and standby letters of credit approach their expiration dates.

At December 31, 2012 and 2011, the Company had the following financial instruments outstanding, whose contract amounts represent credit risk:

	Contract Amount
(Dollars in thousands)	2012		2011
Commitments to grant loans	$	192,295	$	243,458
Unfunded commitments under lines of credit		2,372,971		1,773,601
Commercial and standby letters of credit		62,207		49,530

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to be drawn upon, the total commitment amounts generally represent future cash requirements. The Company evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the counterparty.

Unfunded commitments under commercial lines-of-credit, revolving credit lines and overdraft protection agreements are commitments for possible future extensions of credit to existing customers. Many of these types of commitments do not contain a specified maturity date and may not be drawn upon to the total extent to which the Company is committed.

Commercial and standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. These guarantees are primarily issued to support public and private borrowing arrangements, including commercial paper issuance, bond financing, and similar transactions. The credit risk involved in issuing letters or credit is essentially the same as that involved in extending loan facilities to customers and as such, are collateralized when necessary, generally in the form of marketable securities and cash equivalents.

Legal proceedings

The nature of the business of the Company’s banking and other subsidiaries ordinarily results in a certain amount of claims, litigation, investigations and legal and administrative cases and proceedings, all of which are considered incidental to the normal conduct of business. Some of these claims are against entities or assets of which the Company is a successor or acquired in business acquisitions, and certain of these claims will be covered by loss sharing agreements with the FDIC. The Company has asserted defenses to these litigation claims and, with respect to such legal proceedings, intends to continue to defend itself vigorously, litigating or settling cases according to management’s judgment as to what is in the best interest of the Company and its shareholders.

The Company assesses its liabilities and contingencies in connection with outstanding legal proceedings utilizing the latest information available. Where it is probable that the Company will incur a loss and the amount of the loss can be reasonably estimated, the Company records a liability in its consolidated financial statements. These legal reserves may be increased or decreased to reflect any relevant developments on a quarterly basis. Where a loss is not probable or the amount of loss is not estimable, the Company does not accrue legal reserves. While the outcome of legal proceedings is inherently uncertain, based on information currently available, advice of counsel and available insurance coverage, the Company’s management believes that it has established appropriate legal reserves. Any liabilities arising from pending legal proceedings are not expected to have a material adverse effect on the Company’s consolidated financial position, consolidated results of operations or consolidated cash flows. However, in the event of unexpected future developments, it is possible that the ultimate resolution of these matters, if unfavorable, may be material to the Company’s consolidated financial position, consolidated results of operations or consolidated cash flows.
