Item 1.  BUSINESS

Unless this Annual Report on Form 10-K indicates otherwise, or the context otherwise requires, the terms “we,” “our,” “us,” and “the Company,” as used herein refer to Bank of the Ozarks, Inc. and its subsidiaries, including Bank of the Ozarks, which we sometimes refer to as “Bank of the Ozarks,” “our bank subsidiary,” or “the Bank.”

The disclosures set forth in this item are qualified by Item 1A. Risk Factors, the section captioned “Forward-Looking Information” and other cautionary statements set forth elsewhere in this Annual Report on Form 10-K.

General

Bank of the Ozarks, Inc. (the “Company”) was incorporated in June 1981 as an Arkansas corporation and is a bank holding company registered under the Bank Holding Company Act of 1956. We own an Arkansas state chartered subsidiary bank, Bank of the Ozarks (the “Bank”). At December 31, 2015, the Company, through the Bank, conducted operations through 174 offices, including 81 offices in Arkansas, 28 in Georgia, 25 in North Carolina, 22 in Texas, 10 in Florida, three in Alabama, two each in South Carolina and New York and one in California. As of December 31, 2015, we own Ozark Capital Statutory Trust II, Ozark Capital Statutory Trust III, Ozark Capital Statutory Trust IV and Ozark Capital Statutory Trust V (collectively, the “Ozark Trusts”), and, as a result of our February 10, 2015 acquisition of Intervest Bancshares Corporation (“Intervest”), we own Intervest Statutory Trust II, Intervest Statutory Trust III, Intervest Statutory Trust IV and Intervest Statutory Trust V (collectively, the “Intervest Trusts”; and together with the Ozark Trusts, the “Trusts”).  Each of the Trusts is a 100%-owned finance subsidiary business trust formed in connection with the issuance of certain subordinated debentures and related trust preferred securities.  We also own, indirectly through the Bank, a subsidiary engaged in the development of real estate, a subsidiary that owns private aircraft and various other entities that hold foreclosed assets or tax credits or engage in other activities. At December 31, 2015, we had total assets of $9.88 billion, total loans and leases, including purchased loans, of $8.33 billion, total deposits of $7.97 billion and total common stockholders’ equity of $1.46 billion. Net interest income for 2015 was $382 million, net income available to common stockholders was $182 million and diluted earnings per common share were $2.09.

We provide a wide range of retail and commercial banking services. Deposit services include checking, savings, money market, time deposit and individual retirement accounts. Loan services include various types of real estate, consumer, commercial, industrial and agricultural loans and various leasing services. We also provide mortgage lending; treasury management services for businesses, individuals and non-profit and governmental entities including wholesale lock box services; remote deposit capture services; trust and wealth management services for businesses, individuals and non-profit and governmental entities including financial planning, money management, custodial services and corporate trust services; real estate appraisals; ATMs; telephone banking; online and mobile banking services including electronic bill pay and consumer mobile deposits; debit cards, gift cards and safe deposit boxes, among other products and services. Through third party providers, we offer credit cards for consumers and businesses, processing of merchant debit and credit card transactions, and full-service investment brokerage services. While we provide a wide variety of retail and commercial banking services, we operate in only one segment. No revenues are derived from foreign countries and no single external customer comprises more than 10% of our revenues.

Growth and Expansion

De Novo Growth

With five banking offices in 1994, we commenced an expansion strategy, via de novo branching, into selected Arkansas markets.  Since embarking on this strategy, we have added one or more new banking offices in most years.

In 1998 and 1999, we expanded into Arkansas’ then three largest cities, Little Rock, Fort Smith and North Little Rock.  While we opened a few additional de novo offices in smaller Arkansas communities, the majority of our Arkansas expansion since 1998 has been in these cities, surrounding communities and in other Arkansas counties which are among the top ten counties in Arkansas in terms of bank deposits.

In 2001, we opened a loan production office in Charlotte, North Carolina, which was subsequently converted to a retail banking office in 2013.  In 2003, we opened a loan production office in Dallas, Texas for our Real Estate Specialties Group, or RESG, which was subsequently converted to a retail banking office in 2004.  Our RESG originates and services most of our larger, more complex real estate lending transactions.  Subsequent to the opening of our initial RESG office in Dallas, we have opened additional RESG loan production offices in Austin, Texas (2012); Atlanta, Georgia (2012); New York, New York (2013); Houston, Texas (2014); and Los Angeles, California (2014).  Our RESG offices have contributed significantly to our growth in non-purchased loans and leases in recent years.  

3

We have continued our growth and de novo branching strategy.  In 2014, in addition to opening RESG loan production offices in Houston and Los Angeles, we also opened our third retail banking office in Bradenton, Florida and our first retail banking offices in Cornelius, North Carolina and in Hilton Head Island, South Carolina.  In 2015 we opened two additional loan production offices, one in Little Rock, Arkansas and one in Greensboro, North Carolina, and we opened our fourth retail banking office in Houston, Texas.

We intend to continue our growth strategy in future years through the opening of additional branches and loan production offices as our needs and resources permit. Opening new offices is subject to local banking market conditions, availability of suitable sites, hiring qualified personnel, obtaining regulatory and other approvals and many other conditions and contingencies that we cannot predict with certainty. We may increase or decrease our expected number of new office openings as a result of a variety of factors including our financial results, changes in economic or competitive conditions, strategic opportunities or other factors.

Acquisitions

We have achieved substantial growth through a combination of organic growth and acquisitions, including traditional acquisitions and acquisitions assisted by the Federal Deposit Insurance Corporation (“FDIC”). Since 2010, we have completed 13 acquisitions and in 2015, we announced two additional acquisitions, both of which are expected to close late in the first quarter or in the second quarter of 2016.

FDIC-Assisted Acquisitions.  During 2010 and 2011, we acquired substantially all of the assets and assumed substantially all of the deposits and certain other liabilities of the following seven failed financial institutions in FDIC-assisted acquisitions:  

· March 2010, Unity National Bank (Cartersville, Georgia)

· July 2010, Woodlands Bank (Bluffton, South Carolina)

· September 2010, Horizon Bank (Bradenton, Florida)

· December 2010, Chestatee State Bank (Dawsonville, Georgia)

· January 2011, Oglethorpe Bank (Brunswick, Georgia)

· April 2011, First Choice Community Bank (Dallas, Georgia)

· April 2011, The Park Avenue Bank  (Valdosta, Georgia)

Most of the loans and foreclosed assets acquired in each of these FDIC–assisted acquisitions were subject to loss share agreements with the FDIC whereby we were indemnified against a portion of the losses on loans and foreclosed assets covered by FDIC loss share agreements. During the fourth quarter of 2014, we entered into agreements with the FDIC terminating the loss share agreements for all seven of the FDIC-assisted acquisitions.  All rights and obligations of the parties under the FDIC loss share agreements were eliminated under these termination agreements.  Despite the termination of loss share with the FDIC, the terms of the purchase and assumption agreements for each of these FDIC-assisted acquisitions continue to provide for the FDIC to indemnify us against certain claims, including claims with respect to assets, liabilities or any affiliate not acquired or otherwise assumed by us and with respect to claims based on any action by directors, officers or employees of each of these failed financial institutions.

Traditional Acquisitions.  In December 2012, we completed our acquisition of Genala Banc, Inc. (“Genala”) and The Citizens Bank, its wholly-owned bank subsidiary, for an aggregate of $13.4 million in cash and 847,232 shares of our common stock valued at $14.1 million. This was our first traditional acquisition since 2003. Genala’s bank subsidiary operated one retail banking office in Geneva, Alabama.

In July 2013, we completed our acquisition of The First National Bank of Shelby (“First National Bank”) in Shelby, North Carolina for an aggregate of $8.4 million of cash and 2,514,770 shares of our common stock valued at $60.1 million.  The First National Bank acquisition expanded our service area in North Carolina by adding 14 retail banking offices in Shelby, North Carolina and surrounding communities.  In 2013 we closed one of the acquired offices in Shelby, North Carolina.  

In March 2014, we completed our acquisition of Bancshares, Inc. (“Bancshares”) of Houston, Texas and OMNIBANK, N.A., its wholly-owned bank subsidiary, for an aggregate of $21.5 million in cash.  The Bancshares acquisition expanded our service area in South Texas by adding three retail banking offices in Houston and one retail banking office each in Austin, Cedar Park, Lockhart and San Antonio.

In May 2014, we completed our acquisition of Summit Bancorp, Inc. (“Summit”) and Summit Bank, its wholly-owned bank subsidiary, for an aggregate of $42.5 million in cash and 5,765,846 shares of our common stock valued at $166.4 million.  The Summit acquisition expanded our service area in central, south and western Arkansas by adding 23 retail banking locations and one loan production office.  During 2014 we closed eight Arkansas banking offices in locations where we had excess branch capacity, six of which were acquired in the Summit acquisition, and we closed the loan production office acquired in the Summit acquisition.

4

On February 10, 2015, we completed our acquisition of Intervest and its wholly-owned bank subsidiary, Intervest National Bank, headquartered in New York, New York, whereby we acquired all of the outstanding common stock of Intervest in exchange for 6,637,243 shares of our common stock (plus cash in lieu of fractional shares) in a transaction valued at approximately $238.5 million.  The Intervest acquisition added seven retail banking offices including one in New York City, five in Clearwater, Florida and one in Pasadena, Florida.  During 2015 we closed one of the acquired offices in Clearwater, Florida.

On August 5, 2015, we completed our acquisition of Bank of the Carolinas Corporation (“BCAR”) and Bank of the Carolinas, its wholly-owned bank subsidiary, whereby we acquired all of the outstanding BCAR common stock in exchange for an aggregate of 1,447,620 shares of our common stock (plus cash in lieu of fractional shares) in a transaction valued at approximately $65.4 million.  The BCAR acquisition expanded our operations in North Carolina by adding eight retail banking offices, including one office each in Advance, Asheboro, Concord, Harrisburg, Landis, Lexington, Mocksville and Winston-Salem.

On October 19, 2015, we entered into a definitive agreement and plan of merger (the “C&S Agreement”) with Community & Southern Holdings, Inc. (“C&S”) and its wholly-owned bank subsidiary Community & Southern Bank, whereby we expect to acquire all of the outstanding common stock and equity awards of C&S in a transaction valued at approximately $799.6 million.  C&S is headquartered in Atlanta, Georgia and operates 47 retail banking offices throughout Georgia and one retail banking office in Jacksonville, Florida.  At December 31, 2015, C&S had approximately $4.2 billion in total assets, approximately $3.1 billion in total loans, approximately $3.7 billion in total deposits and approximately $455 million in stockholders’ equity.

On November 9, 2015, we entered into a definitive agreement and plan of merger (the “C1 Agreement”) with C1 Financial, Inc. (“C1”) and its wholly-owned bank subsidiary C1 Bank, whereby we expect to acquire all of the outstanding common stock of C1 in a transaction valued at approximately $402.5 million.  C1 is headquartered in St. Petersburg, Florida and operates 32 retail banking offices on the west coast of Florida and in Miami-Dade and Orange Counties.  At December 31, 2015, C1 had approximately $1.7 billion in total assets, approximately $1.4 billion in total loans, approximately $1.3 billion in total deposits and approximately $201 million in stockholders’ equity.

Future Growth Strategy

We expect to continue growing through both our de novo branching strategy and traditional acquisitions. With respect to de novo branching strategy, future de novo branches are expected to be focused in states where we currently have banking offices and in larger markets and metropolitan areas across the United States where we currently do not have offices and believe we can generate significant growth from one or two strategically located offices in each such market. In 2016 we expect to open three retail banking offices in Arkansas (Siloam Springs, Fayetteville and Springdale).  Future RESG loan production offices are expected to be focused in strategically important markets (most likely San Francisco in late February 2016 and offices in Seattle, Washington, D.C., Boston and Chicago at later dates). With respect to traditional acquisitions, we are seeking acquisitions that are either immediately accretive to book value, tangible book value and diluted earnings per share, or strategic in location, or both.

Lending and Leasing Activities  

Administration of the Company’s lending function is the responsibility of our Chief Executive Officer (“CEO”), Chief Credit Officer (“CCO”), Chief Lending Officer (“CLO”), our Director of Community Bank Lending (“Dir-CBL”) and certain other senior lending officers. These officers perform their lending duties subject to the oversight and policy direction of our board of directors and the directors’ loan committee.  Loan or lease authority is granted to our CEO, CCO, CLO and Dir-CBL by the board of directors.  Other lending officers are granted authority by the directors’ loan committee on the recommendation of appropriate senior officers. Loans and leases and aggregate loan and lease relationships exceeding $10 million (up to the limits established by our board of directors) must be approved by the directors’ loan committee.  

Interest rates charged by the Bank vary with degree of risk, type, size, complexity, repricing frequency and other relevant factors associated with the loan or lease. Competition from other financial services companies also impacts interest rates charged on loans and leases.

Our designated compliance and loan review officers are primarily responsible for the Bank’s compliance and loan review functions. Periodic reviews are performed to evaluate asset quality and the effectiveness of loan and lease administration. The results of such evaluations are included in reports which describe any identified deficiencies, recommendations for improvement and management’s proposed action plan for curing or addressing identified deficiencies and recommendations. Such reports are provided to and reviewed by the audit committee.

Our loan portfolio, including purchased loans, includes most types of real estate loans, consumer loans, commercial and industrial loans, agricultural loans and other types of loans. While a significant portion of the properties collateralizing our loan portfolio have historically been located within the trade areas of our offices, we have expanded the geographic distribution of our loan

5

portfolio in recent years.  Included in Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) included elsewhere in this Annual Report on Form 10-K is an analysis of our real estate loan portfolio based on metropolitan statistical area or other geographic area in which the principal collateral is located.  Our lease portfolio consists primarily of small ticket direct financing commercial equipment leases. The equipment collateral securing our lease portfolio is located throughout the United States.

Real Estate Loans.  Our portfolio of real estate loans includes loans secured by residential 1-4 family, non-farm/non-residential, agricultural, construction/land development, multifamily residential properties and other land loans. Non-farm/non-residential loans include those secured by real estate mortgages on owner-occupied commercial buildings of various types, leased commercial, retail and office buildings, hospitals, nursing and other medical facilities, hotels and motels, and other business and industrial properties. Agricultural real estate loans include loans secured by farmland and related improvements, including some loans guaranteed by the Farm Service Agency. Real estate construction/land development loans include loans secured by vacant land, loans to finance land development or construction of industrial, commercial, residential or farm buildings or additions or alterations to existing structures. Included in our residential 1-4 family loans are home equity lines of credit.

We offer a variety of real estate loan products that are generally amortized over five to thirty years, payable in monthly or other periodic installments of principal and interest, and due and payable in full (unless renewed) at a balloon maturity generally within one to seven years. Certain loans may be structured as term loans with adjustable interest rates (adjustable daily, monthly, semi-annually, annually, or at other regular adjustment intervals usually not to exceed five years). A substantial portion of our loans, including most of our real estate loans, have adjustable interest rates and many of such adjustable rate loans have established “floor” and “ceiling” interest rates.

Residential 1-4 family loans are underwritten primarily based on the borrower’s ability to repay, including prior credit history, and the value of the collateral.

Other real estate loans are underwritten based on the ability of the property, in the case of income producing property, or the borrower’s business to generate sufficient cash flow to amortize the debt. Secondary emphasis is placed upon collateral value, financial strength of any guarantors and other factors.

Loans collateralized by real estate have generally been originated with loan-to-appraised-value (“LTV”) ratios of not more than 89% for residential 1-4 family, 85% for other residential and other improved property, 80% for construction loans secured by commercial, multifamily and other non-residential properties, 75% for land development loans and 65% for raw land loans. We typically require mortgage title insurance in the amount of the loan and hazard insurance on improvements. Documentation requirements vary depending on loan size, type, degree of risk, complexity and other relevant factors.  Included in MD&A to this Annual Report on Form 10-K is an analysis of the weighted-average LTV and loan-to-cost ratios of our construction and development loan portfolio.

Consumer Loans.  Our portfolio of consumer loans generally includes loans to individuals for household, family and other personal expenditures. Proceeds from such loans are used to, among other things, fund the purchase of automobiles, recreational vehicles, boats, mobile homes and for other similar purposes. These consumer loans are generally collateralized and have terms typically ranging up to 72 months, depending upon the nature of the collateral, size of the loan, and other relevant factors.

Consumer loans generally have higher interest rates. However, such loans pose additional risks of collectability and loss when compared to certain other types of loans. The borrower’s ability to repay is of primary importance in the underwriting of consumer loans.

Commercial and Industrial Loans and Leases.  Our commercial and industrial loan portfolio consists of loans for commercial, industrial and professional purposes including loans to fund working capital requirements (such as inventory, floor plan and receivables financing), purchases of machinery and equipment and other purposes. We offer a variety of commercial and industrial loan arrangements, including term loans, balloon loans and lines of credit, including some loans guaranteed by the Small Business Administration, with the purpose and collateral supporting a particular loan determining its structure. These loans are offered to businesses and professionals for short and medium terms on both a collateralized and uncollateralized basis. As a general practice, we obtain as collateral a lien on furniture, fixtures, equipment, inventory, receivables or other assets. In 2014 we formed the Corporate Loan Specialties Group (“CLSG”) for the purpose of acquiring Shared National Credits (“SNC”). SNC generally include syndicated loans and loan commitments, letters of credit, commercial leases, and other forms of credit. At December 31, 2015, our SNC portfolio totaled approximately $84 million.

Our leases are primarily equipment leases for commercial, industrial and professional purposes, have terms generally ranging up to 60 months and are collateralized by a lien on the lessee’s interest in the leased property.

6

Commercial and industrial loans and leases, including our SNC portfolio, typically are underwritten on the basis of the borrower’s or lessee’s ability to make repayment from the cash flow of its business and generally are collateralized by business assets. As a result, such loans and leases involve additional complexities, variables and risks and require more thorough underwriting and servicing than certain other types of loans and leases.

Agricultural (Non-Real Estate) Loans.  Our portfolio of agricultural (non-real estate) loans includes loans for financing agricultural production, including loans to businesses or individuals engaged in the production of timber, poultry, livestock or crops. Our agricultural (non-real estate) loans are generally secured by farm machinery, livestock, crops, vehicles or other agricultural-related collateral. A portion of our portfolio of agricultural (non-real estate) loans is comprised of loans to individuals which would normally be characterized as consumer loans but for the fact that the individual borrowers are primarily engaged in the production of timber, poultry, livestock or crops.

Deposits  

We offer an array of deposit products consisting of non-interest bearing checking accounts, interest bearing transaction accounts, business sweep accounts, savings accounts, money market accounts, time deposits, including access to products offered through the various CDARS^® programs, and individual retirement accounts. Rates paid on such deposits vary among banking markets and deposit categories due to different terms and conditions, individual deposit size, services rendered and rates paid by competitors on similar deposit products. We act as depository for a number of state and local governments and government agencies or instrumentalities. Such public funds deposits are often subject to competitive bid and in many cases must be secured by pledging a portion of our investment securities or a letter of credit.

Our deposits come primarily from within our trade area. As of December 31, 2015 we had $677 million in “brokered deposits,” defined as deposits which, to our knowledge, have been placed with us by a person who acts as a broker in placing these deposits on behalf of others or is otherwise deemed to be “brokered” by bank regulatory authority rules and regulations. Brokered deposits are typically from outside our primary trade area, and such deposit levels may vary from time to time depending on competitive interest rate conditions and other factors.

Other Banking Services

Mortgage Lending.  We offer a broad array of residential mortgage products including long-term fixed rate and variable rate loans which are sold on a servicing-released basis in the secondary mortgage market. These loans are originated primarily through our larger banking offices located in Arkansas, Texas, Georgia, North Carolina, Florida and in certain of our other acquired offices.  In addition to long-term secondary market loans, we offer a small number of fixed rate loan products which balloon periodically, typically every eight to nine years. We retain these loans in our loan portfolio.

Trust and Wealth Management Services.  We offer a broad array of trust and wealth management services from our headquarters in Little Rock, Arkansas, with additional staff in Bluffton, South Carolina, Texarkana, Texas and Charlotte and Shelby, North Carolina.  These trust and wealth management services include personal trusts, custodial accounts, investment management accounts, retirement accounts, corporate trust services including trustee, paying agent and registered transfer agent services, and other incidental services. As of December 31, 2015, total trust assets were approximately $1.85 billion compared to approximately $1.80 billion as of December 31, 2014 and approximately $1.48 billion as of December 31, 2013.

Market Area and Competition

At December 31, 2015, we conducted banking operations through 174 offices, including 81 offices in Arkansas, 28 in Georgia, 25 in North Carolina, 22 in Texas, 10 in Florida, three in Alabama, two offices each in South Carolina and New York and one office in California.

The banking industry in our market areas is highly competitive. In addition to competing with other commercial and savings banks and savings and loan associations, we compete with credit unions, finance companies, leasing companies, mortgage companies, insurance companies, brokerage and investment banking firms, asset-based non-bank lenders and many other financial service firms. Competition is based on interest rates offered on deposit accounts, interest rates charged on loans and leases, fees and service charges, the quality and scope of the services rendered, the convenience of banking facilities and, in the case of loans to commercial borrowers, relative lending limits, as well as other factors.

A substantial number of the commercial banks operating in our market areas are branches or subsidiaries of much larger organizations affiliated with statewide, regional or national banking companies and as a result may have greater resources and lower costs of funds than the Company. Additionally, we face competition from a large number of community banks, including de novo community banks, many of which have senior management who were previously with other local banks or investor groups with strong local business and community ties. Despite the highly competitive environment, we believe we will continue to be competitive because of our expertise in real estate lending, our strong commitment to quality customer service, convenient local branches, active community involvement and competitive products and pricing. The ability to access and use technology is an increasingly competitive factor in the finance services industry.  Technology is not only important with respect to delivery of financial services and protection of the security of customer information but also in processing information.  We must continually make technology investments to remain competitive in the finance services industry.

Employees

At December 31, 2015, we employed 1,642 full-time equivalent employees. None of our employees was represented by any union or similar group. We have not experienced any labor disputes or strikes arising from any organized labor groups. We believe our employee relations are good.

SUPERVISION AND REGULATION

In addition to the generally applicable state and federal laws governing businesses and employers, bank holding companies and banks are extensively regulated under both federal and state law. With few exceptions, state and federal banking laws have as their principal objective either the maintenance of the safety and soundness of the Deposit Insurance Fund (“DIF”) of the FDIC or the protection of consumers or classes of consumers, rather than the specific protection of our shareholders. Bank holding companies and banks that fail to conduct their operations in a safe and sound manner or in compliance with applicable laws can be compelled by the regulators to change the way they do business and may be subject to regulatory enforcement actions, including civil money penalties and restrictions imposed on their operations. To the extent that the following information describes statutory and regulatory

9

provisions, it is qualified in its entirety by reference to those particular statutory and regulatory provisions. Any change in applicable laws or regulations, and in their application by regulatory agencies, may have an adverse effect on our results of operation and financial condition.

Primary Federal Regulators

The primary federal banking regulatory authority for the Company is the Board of Governors of the Federal Reserve System (the “FRB”), acting pursuant to its authority to regulate bank holding companies. The primary federal regulatory authority of the Bank is the FDIC because the Bank is an insured depository institution which is not a member bank of the FRB.

Recent Legislative and Regulatory Initiatives to Address Current Financial and Economic Conditions

Dodd-Frank Wall Street Reform and Consumer Protection Act.  On July 21, 2010, the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Dodd-Frank Act”) was signed into law. The goals of the Dodd-Frank Act include restoring public confidence in the financial system following the financial and credit crises, preventing another financial crisis and allowing regulators to identify failings in the system before another crisis can occur. Further, the Dodd-Frank Act is intended to affect a fundamental restructuring of federal banking regulation by taking a systemic view of regulation rather than focusing on prudential regulation of individual financial institutions. However, the Dodd-Frank Act itself may be more appropriately considered as a blueprint for regulatory change, as many of the provisions in the Dodd-Frank Act require that regulatory agencies draft implementing regulations.  Implementation of the Dodd-Frank Act has had and will continue to have a broad impact on the financial services industry by introducing significant regulatory and compliance changes including, among other things:

· Changing the assessment base for federal deposit insurance from the amount of insured deposits to average consolidated total assets less average tangible equity, eliminating the ceiling and increasing the size of the floor of the DIF, and offsetting the impact of the increase in the minimum floor on institutions with less than $10 billion in assets.

· Making permanent the $250,000 limit for federal deposit insurance, increasing the cash limit of Securities Investor Protection Corporation protection to $250,000 and providing that unlimited federal deposit insurance for non-interest bearing demand transaction accounts at all insured depository institutions would expire after December 31, 2012.

· Eliminating the requirement that the FDIC pay dividends from the DIF when the reserve ratio is between 1.35% and 1.5%, but continuing the FDIC’s authority to declare dividends when the reserve ratio at the end of a calendar year is at least 1.5%. However, the FDIC is granted sole discretion in determining whether to suspend or limit the declaration or payment of dividends.

· Repealing the federal prohibition on payment of interest on demand deposits, thereby permitting depository institutions to pay interest on business transaction and other accounts.

· Implementing certain corporate governance revisions that apply to all public companies, including regulations that require publicly traded companies to give shareholders a non-binding advisory vote to approve executive compensation, commonly referred to as a “say-on-pay” vote and an advisory role on so-called “golden parachute” payments in connection with approvals of mergers and acquisitions; new director independence requirements and considerations to be taken into account by compensation committees and their advisers relating to executive compensation; additional executive compensation disclosures; and a requirement that companies adopt a policy providing for the recovery of executive compensation in the event of a restatement of its financial statements, commonly referred to as a “clawback” policy.

· Centralizing responsibility for consumer financial protection by creating a new independent federal agency, the Consumer Financial Protection Bureau (the “CFPB”), responsible for implementing federal consumer protection laws to be applicable to all depository institutions, including the Company and the Bank.

· Imposing new requirements for mortgage lending, including new minimum underwriting standards, limitations with respect to prepayment penalties, prohibitions on certain yield-spread compensation to mortgage originators, establishment of new “qualified residential mortgage” standards intended to protect consumers, prohibition and limitation of certain mortgage terms and imposition of new mandated disclosures to mortgage borrowers.

· Imposing new limits on affiliate transactions and causing derivative transactions to be subject to lending limits and other restrictions, including adoption of the so-called “Volcker Rule” regulating transactions in derivative securities.

· Permitting national and state banks to establish de novo interstate branches at any location where a bank based in another state could establish a branch, and requiring that bank holding companies and banks be well-capitalized and well-managed in order to acquire banks located outside their home state.

10

· Applying the same leverage and risk-based capital requirements to holding companies that apply to insured depository institutions, including the phase out of the Company’s existing and acquired trust preferred securities from qualifying as Tier 1 capital should our total consolidated assets exceed $15 billion, although such securities will continue to be included in total risk-based capital. 

· Limiting debit card interchange fees that financial institutions with $10 billion or more in assets are permitted to charge their customers, commonly referred to as the “Durbin Amendment.”

· Increasing the dollar threshold below which consumers are required to be provided with certain disclosures under the Truth In Lending Act of 1968, as amended (“TILA”) and the Consumer Leasing Act with respect to consumer credit transactions and personal property leases for personal, family, or household use exceeding four months in duration, as well as requiring such disclosures without regard for dollar limits or length of time where security interests will be given in real estate or personal property used or expected to be used as, or in conjunction with, a consumer’s principal residence.

· Implementing regulations to incentivize and protect individuals, commonly referred to as whistleblowers, to report violations of federal securities laws.

As discussed further throughout this section, many aspects of the Dodd-Frank Act continue to be subject to rulemaking and will take effect over several additional years, making it difficult to anticipate the overall financial impact on us or across the industry. The changes resulting from the Dodd-Frank Act may impact the profitability of our business activities, require changes to certain of our business practices, impose upon us more stringent capital, liquidity and leverage requirements or otherwise adversely affect our business. These changes may also require us to invest significant management attention and resources to evaluate and make any changes necessary to comply with new statutory and regulatory requirements.

At December 31, 2015, our total assets were $9.88 billion.  As we continue to grow, we will also need to comply with certain additional requirements created by the Dodd-Frank Act that apply only to bank holding companies and banks with $10 billion or more in total assets. Failure to comply with the new requirements would negatively impact our results of operations and financial condition and could limit our growth or expansion activities. While we cannot predict what effect any presently contemplated or future changes in the laws or regulations or their interpretations would have on us, such changes could be materially adverse to us and our investors.

Risk Committee. Publicly traded bank holding companies with $10 billion or more in total assets are required to establish a risk committee responsible for oversight of enterprise-wide risk management practices. The committee must include at least one risk management expert with experience in managing risk exposures of large, complex firms.

Stress Testing. Pursuant to the Dodd-Frank Act, any banking organization, including both a bank holding company and a depository institution, with more than $10 billion in total consolidated assets and regulated by a federal financial regulatory agency is required to conduct annual stress tests to ensure it has sufficient capital during periods of economic downturn. The FRB and FDIC release stress-test scenarios on February 15 of each year, and banking organizations are required to submit the results of their tests to the appropriate regulator by July 31. The results of each year’s stress tests are publicly disclosed following each banking organization’s submission. A banking organization that crosses the $10 billion total average consolidated assets threshold for four consecutive quarters must conduct its first annual company-run stress test in the calendar year after the year in which it crossed the applicability threshold. Assuming we pass the $10 billion total average consolidated assets threshold in 2016, our first annual stress test will be required for the year ending December 31, 2017 and must be submitted to the appropriate federal regulators by July 31, 2018.  Almost all of our assets are held at the Bank. When the Company’s total assets pass this $10 billion threshold, it is very likely that our banking subsidiary’s total assets will also pass this $10 billion threshold, and we will be required to conduct stress tests at both the holding company and bank level. The Company’s capital ratios reflected in the stress test calculations will be an important factor considered by our regulators in evaluating the capital adequacy of the Company and the Bank, in evaluating any proposed acquisitions for approval and in determining whether proposed payments of dividends or stock repurchases may be an unsafe or unsound practice.

Debit Interchange Fees. Section 1075 of the Dodd-Frank Act, often referred to as the Durbin Amendment, amends the federal Electronic Fund Transfer Act to set standards for the pricing of interchange transaction fees on electronic debit transactions, called “swipe fees.” FRB rules applicable to financial institutions that have assets of $10 billion or more provide that the maximum permissible interchange fee for an electronic debit transaction is the sum of 21 cents per transaction and 5 basis points multiplied by the value of the transaction. A debit card issuer may recover up to 1 cent of its debit card interchange fee if the card issuer develops and implements policies and procedures reasonably designed to achieve certain fraud-prevention standards. The FRB also has rules governing routing and exclusivity that require issuers to offer two unaffiliated networks for routing transactions on each debit or prepaid product.  Currently, we are not required to comply with the Durbin Amendment’s limitations on swipe fees due to an exemption for debit card issuers which, together with their affiliates, parent companies, and subsidiaries have assets of less than $10 billion. Assuming our total consolidated assets pass the $10 billion threshold at December 31, 2016, we will have to comply with the restrictions on swipe fees beginning on July 1, 2017 (i.e., the calendar year following the year in which we surpass the threshold).

11

Losing the exemption from the Durbin Amendment’s requirements is expected to negatively affect the amount of revenue we receive from swipe fees.

Prohibition on Propriety Trading and Certain Fund Relationships. On December 10, 2013, federal financial regulators released final rules implementing Section 619 of the Dodd-Frank Act, also known as the Volcker Rule, which prohibits both bank holding companies and banks from engaging in proprietary trading and from acquiring or retaining an ownership interest in, sponsoring, or having certain relationships with a hedge fund or private equity fund. On December 18, 2014, the FRB granted a second one-year extension of the Volcker Rule conformance period to July 21, 2016 for existing investments in and relationships with covered funds (relationships existing prior to December 31, 2013). The FRB has also announced its intention to further extend the Volcker Rule conformance period to July 21, 2017 to company ownership interests in and relationships with legacy covered funds. The final rules are highly complex, and many aspects of their application remain uncertain. We do not currently anticipate that the Volcker Rule will have a material effect on our operations since we do not engage in the businesses prohibited by the Volcker Rule. We may incur costs if we are required to adopt additional policies and systems to ensure compliance with the Volcker Rule, but any such costs are not expected to be material. Because many of the effects of the Volcker Rule may become apparent only over several years as the federal financial regulatory agencies apply the rule in practice, the precise financial impact of the rule on us, our customers or the financial industry more generally cannot currently be determined.

Emergency Economic Stabilization Act.  The U.S. Congress, the U.S. Department of the Treasury (“Treasury”), and federal banking regulators took broad action, beginning in the third quarter of 2008 and continuing to the present time, to strengthen the capital and liquidity positions of financial institutions in the U.S. and to address volatility in the financial markets and the financial services industry. On October 3, 2008, the Emergency Economic Stabilization Act of 2008 (“EESA”) became law. On February 17, 2009, the American Recovery and Reinvestment Act of 2009 (“Recovery Act”), more commonly known as the economic stimulus or economic recovery package became law. The Recovery Act, which amends EESA, includes a wide variety of programs intended to stimulate the economy and provide for extensive infrastructure, energy, health, and education needs. Under the Troubled Asset Relief Program (“TARP”) authorized by EESA, the Treasury established a capital purchase program (“CPP”) providing for the purchase of senior preferred shares of qualifying U.S. controlled banks, savings associations and certain bank and savings and loan holding companies. Financial institutions participating in the TARP or CPP programs were subject to numerous Recovery Act provisions relating to executive compensation, which included restrictions on bonus and incentive compensation, severance compensation and so-called “golden parachutes” to the institution’s executive officers, and provided for “clawbacks” or mandatory repayments of bonuses, retention awards or incentive compensation payments to a larger group of employees if it were later determined that such compensation payments were based on materially inaccurate financial results, as well as concerning other matters regarding executive compensation policies and practices.

In December 2008, pursuant to the TARP program, the Treasury purchased $75 million of a newly created series of our preferred stock along with a warrant to purchase shares of our common stock.  In November 2009, we redeemed the preferred stock from Treasury, returned to Treasury the original investment amount of $75 million, plus accrued and unpaid dividends thereon, and repurchased the warrant from Treasury.  We are no longer a participant in the CPP or TARP programs.

Our issuance of preferred stock to Treasury made us subject to the enforcement and oversight authority of the Office of the Special Inspector General for TARP (“Special Inspector General”). The Special Inspector General retains authority to audit and investigate all aspects of TARP even after the capital we received under the CPP was repaid to Treasury. Although we have not had any Special Inspector General investigations concerning compliance with TARP, we remain subject to requests by the Special Inspector General for documentation pertaining to our compliance with TARP requirements prior to our repayment of the capital received under the CPP.

Except for the statutory mandate regarding clawbacks for compensation paid or accrued while Treasury held the preferred stock and any future investigations by the Special Inspector General as described above, we are no longer subject to the executive compensation restrictions and related mandates imposed by EESA and the Recovery Act.

The Making Home Affordable Program. During March 2009, Treasury announced the “Making Home Affordable” program (the “MHA”) intended to provide assistance to homeowners by, among other things, introducing new refinancing and loan modification programs. The refinancing program is intended to allow homeowners who have loans either owned or guaranteed by Freddie Mac or Fannie Mae, and who have seen the value of their homes decline, to refinance their existing mortgages thereby providing them with lower mortgage payments. As part of the loan modification program, which is intended to prevent residential mortgage foreclosures and the resulting loss of home ownership, Treasury issued guidelines designed to enable mortgagors and their mortgage holders to modify existing loans and reduce homeowners’ monthly mortgage payments, thereby reducing the risk of foreclosure. The MHA program was initially scheduled to end on December 31, 2013 but has been extended through December 31, 2016.

Concentrated Commercial Real Estate Lending Regulations. The federal banking agencies, including the FDIC, have promulgated guidance governing financial institutions with concentrations in commercial real estate lending. The guidance provides that a bank has a concentration in commercial real estate lending if (1) total reported loans for construction, land development and other land represent 100% or more of total capital or (2) total reported loans secured by multifamily and non-farm residential

12

properties and loans for construction, land development and other land represent 300% or more of total capital and the bank’s commercial real estate loan portfolio has increased 50% or more during the prior 36 months. Owner occupied loans are excluded from this second category. If a concentration is present, management must employ heightened risk management practices that address key elements, including board and management oversight and strategic planning, portfolio management, development of underwriting standards, risk assessment and monitoring through market analysis and stress testing, and maintenance of increased capital levels as needed to support the level of commercial real estate lending.

The actions described above, together with additional actions announced by Treasury and other regulatory agencies, continue to evolve. It remains unclear at this time what will be the long-term impact on the financial markets and the financial services industry of the Dodd-Frank Act, EESA, TARP, MHA or any of the other liquidity, funding and home ownership initiatives of Treasury and other bank regulatory agencies that have been previously announced, or any additional programs that may be initiated in the future. However, given the sweeping nature of the Dodd-Frank Act and other federal government initiatives, we expect that our regulatory compliance costs will continue to increase over time.

Other Federal Legislation and Regulation

Bank Holding Company Act. We are subject to supervision by the FRB under the provisions of the Bank Holding Company Act of 1956, as amended (the “BHCA”). The BHCA restricts the types of activities in which bank holding companies may engage and imposes a range of supervisory requirements on their activities, including regulatory enforcement actions for violations of laws and policies. The BHCA limits our activities and any companies controlled by our bank holding company to the activities of banking, managing and controlling banks, furnishing or performing services for its subsidiaries, and any other activity that the FRB determines to be incidental to or closely related to banking. These restrictions also apply to any company in which we own 5% or more of the voting securities.

Before a bank holding company engages in any non-bank-related activity, either by acquisition or commencement of de novo operations, it must comply with the FRB’s notification and approval procedures. In reviewing these notifications, the FRB considers a number of factors, including the expected benefits to the public versus the risks of possible adverse effects. In general, the potential benefits include greater convenience to the public, increased competition and gains in efficiency, while the potential risks include undue concentration of resources, decreased or unfair competition, conflicts of interest and unsound banking practices.

Under the BHCA, a bank holding company must obtain FRB approval before engaging in acquisitions of banks or bank holding companies. In particular, the FRB must generally approve the following actions by a bank holding company:

· the acquisition of ownership or control of more than 5% of the voting securities of any bank or bank holding company;

· the acquisition of all or substantially all of the assets of a bank; and

· the merger or consolidation with another bank holding company.

In considering any application for approval of an acquisition or merger, the FRB is required to consider various competitive factors, the financial and managerial resources of the companies and banks concerned, the convenience and needs of the communities to be served, the effectiveness of the applicant in combating money laundering activities, and the applicant’s record of compliance with the Community Reinvestment Act of 1977 (the “CRA”).  The CRA is more particularly described below.

Pursuant to the Dodd-Frank Act, the FRB is now required to also consider the extent to which a proposed acquisition, merger, or consolidation would increase the systemic risk of the banking system. The Dodd-Frank Act also amended the BHCA to require that bank holding companies be well-capitalized and well-managed before acquiring control of a bank in another state.  FRB regulations regard a bank holding company as well-capitalized if it has a total risk-based capital ratio of 10.0% or greater, a Tier 1 risk-based capital ratio of 8.0% or greater, common equity tier 1 capital ratio of 6.5% or greater and a leverage ratio of 5.0% or greater. The Attorney General of the United States may, within 30 days after approval of an acquisition by the FRB, bring an action challenging such acquisition under the federal antitrust laws, in which case the effectiveness of such approval is stayed pending a final ruling by the courts.

Source of Strength Doctrine. The Dodd-Frank Act codifies and expands the existing FRB policy that a bank holding company is required to serve as a source of financial and managerial strength to its subsidiary banks. Under the Dodd-Frank Act, the term “source of financial strength” means the “ability of a company that directly or indirectly controls an insured depository institution to provide financial assistance to such insured depository institution in the event of the financial distress of the insured depository institution.” It is the FRB’s existing policy that a bank holding company should stand ready to use available resources to provide adequate capital to its subsidiary banks during periods of financial stress or adversity and should maintain the financial flexibility and capital-raising capacity to obtain additional resources for assisting its subsidiary banks. Consistent with this, the FRB has stated that, as a matter of prudent banking, a bank holding company should generally not maintain a given rate of cash dividends unless its net income available to common shareholders has been sufficient to fully fund the dividends and the prospective rate of earnings retention appears to be consistent with the organization’s capital needs, asset quality, and overall financial condition.

13

Federal Insurance of Deposit Accounts.  Deposits in the Bank are insured by the FDIC’s DIF, generally up to a maximum of $250,000 per separately insured depositor, pursuant to changes made permanent by the Dodd-Frank Act. The FDIC assesses insured depository institutions to maintain the DIF. No institution may pay a dividend if in default of its deposit insurance assessment.

Under the FDIC’s risk-based assessment system, insured institutions are assigned to a risk category based on supervisory evaluations, regulatory capital levels and other factors. An institution’s assessment rate depends upon the category to which it is assigned and certain adjustments specified by the FDIC, with less risky institutions paying lower assessments.

Pursuant to the Dodd-Frank Act, the FDIC amended its regulations to determine insurance assessments based on the average consolidated assets less the average tangible equity of the insured depository institution during the assessment period. Since the revised base is larger than the previous base, the FDIC also lowered assessment rates so that the rule would not significantly alter the total amount of revenue collected from the industry. The range of adjusted assessment rates is now 2.5 to 45 basis points of the revised assessment base. The rule is expected to benefit smaller financial institutions, which typically rely more on deposits for funding, and shift more of the burden for supporting the insurance fund to larger institutions, which are thought to have greater access to nondeposit funding. When the Bank passes the $10 billion total asset threshold, it will become subject to the assessment rate calculations for larger banks, which will result in higher deposit insurance premiums.

The Dodd-Frank Act increased the minimum target DIF ratio to 1.35% of estimated insured deposits. In October 2010, the FDIC adopted a new DIF restoration plan to ensure that the fund reserve ratio reaches 1.35% by September 30, 2020. The FDIC has established a long-term target for the reserve ratio of 2.0%.  

Insurance of deposits may be terminated by the FDIC upon a finding that an institution has engaged in unsafe or 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.

Capital Adequacy Requirements in Effect as of December 31, 2014. The FRB monitors the capital adequacy of the Company, and the FDIC monitors the capital adequacy of the Bank. The federal bank regulators use a combination of risk-based guidelines and leverage ratios to evaluate capital adequacy.

Under the risk-based capital guidelines, bank regulators assign a risk weight to each category of assets based generally on the perceived credit risk of the asset class. The risk weights are then multiplied by the corresponding asset balances to determine a “risk-weighted” asset base. The minimum ratio of total risk-based capital to risk-weighted assets is 8.0%. At least half of the risk-based capital must consist of Tier 1 capital, which is comprised of common stock, additional paid-in capital, retained earnings, certain types of preferred stock, a limited amount of trust preferred securities and qualifying minority interests in the equity capital accounts of consolidated subsidiaries, and excludes goodwill and various intangible assets. However, a banking organization may reduce the amount of goodwill deducted from Tier 1 capital by the amount of any deferred tax liability associated with that goodwill. The remainder, or Tier 2 capital, may consist of amounts of trust preferred securities and other preferred stock excluded from Tier 1 capital, certain hybrid capital instruments and other debt securities and an allowance for loan and lease losses not to exceed 1.25% of risk-weighted assets. The sum of Tier 1 capital and Tier 2 capital is “total risk-based capital.”

Bank holding companies and banks are also required to comply with minimum leverage ratio requirements.  The leverage ratio is a company’s Tier 1 capital divided by its adjusted average total consolidated assets. Bank holding companies and FDIC-supervised banks, such as the Company and the Bank, respectively, are required to maintain a minimum leverage ratio of 4.0%, unless a different minimum is specified by an appropriate regulatory authority.  In addition, for a depository institution to be considered “well-capitalized” (the highest capital tier) under the regulatory framework for prompt corrective action, its leverage ratio must be at least 5.0%.See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Capital Compliance” for further information on regulatory capital requirements.

In January 2010, the FRB adopted a final rule to amend its general risk-based capital adequacy and advanced risk-based capital adequacy framework and to address the accounting treatment of special purpose entities, known as “variable interest entities” often used in securitizations. The rule requires variable interest entities to be treated as consolidated for risk-based capital purposes. Although we do not believe we currently have any variable interest entities required to be consolidated under GAAP, it is possible that such an entity could be used in future business operations.

Basel III Capital Adequacy Requirements Effective January 1, 2015.  On July 9, 2013, the FDIC and other federal banking regulators revised the risk-based capital requirements applicable to bank holding companies and insured depository institutions, including the Company and the Bank, to make them consistent with agreements that were reached by the Basel Committee on Banking Supervision (“Basel III”) and certain provisions of the Dodd-Frank Act (the “Basel III Rules”). The Basel III Rules became effective for the Company and the Bank on January 1, 2015 (subject to a phase-in period for certain provisions). The Basel III Rules

14

require the maintenance of minimum amounts and ratios of common equity tier 1 capital, tier 1 capital and total capital (as defined in the regulations) to risk-weighted assets (as defined), and of tier 1 capital to adjusted quarterly average assets (as defined).

Under the Basel III Rules, common equity tier 1 capital consists of common stock and paid-in capital (net of treasury stock) and retained earnings. Common equity tier 1 capital is reduced by goodwill, certain intangible assets, net of associated deferred tax liabilities, deferred tax assets that arise from tax credit and net operating loss carryforwards, net of any valuation allowance, and certain other items as specified by the Basel III Rules.

Tier 1 capital includes common equity tier 1 capital and certain additional tier 1 items as provided under the Basel III Rules. The tier 1 capital for the Company consists of common equity tier 1 capital and $118 million of trust preferred securities. The Basel III Rules include certain provisions that would require trust preferred securities to be phased out of qualifying tier 1 capital. Currently, the Company’s trust preferred securities are grandfathered under the Basel III Rules and will continue to be included as tier 1 capital. However, should the Company exceed $15 billion in total assets, the grandfather provisions applicable to its trust preferred securities would no longer apply and such trust preferred securities would no longer be included as tier 1 capital, but would continue to be included as total capital. The common equity tier 1 capital and the tier 1 capital are the same for the Bank.

Basel III Rules allow for insured depository institutions to make a one-time election not to include most elements of accumulated other comprehensive income in regulatory capital and instead effectively use the existing treatment under the general risk-based capital rules. The Company and Bank made this opt-out election in the first quarter of 2015 to avoid significant variations in the level of capital depending upon the impact of interest rate fluctuations on the fair value of our investment securities portfolio.

Total capital includes tier 1 capital and tier 2 capital. Tier 2 capital includes, among other things, the allowable portion of the ALLL and any trust preferred securities that are excluded from tier 1 capital.

The Basel III Rules also changed the risk-weights of assets in an effort to better reflect credit risk and other risk exposures. These include a 150% risk weight (up from 100%) for certain high volatility commercial real estate acquisition, development and construction loans and the unsecured portion of non-residential mortgage loans that are 90 days past due or otherwise on nonaccrual status; a 20% (up from 0%) credit conversion factor for the unused portion of a commitment with an original maturity of one year or less that is not unconditionally cancellable; a 250% risk weight (up from 100%) for mortgage servicing rights and deferred tax assets that are not deducted from capital; and increased risk weights (from 0% to up to 600%) for equity exposures.

The Basel III Rules limit capital distributions and certain discretionary bonus payments if the banking organization does not hold a “capital conservation buffer” consisting of 2.5% of common equity tier 1 capital, tier 1 capital and total capital to risk-weighted assets in addition to the amount necessary to meet minimum risk-based capital requirements. The capital conservation buffer will be phased in beginning January 1, 2016, at 0.625% of risk-weighted assets, increasing each year by that amount until fully implemented at 2.5% on January 1, 2019. When fully phased in on January 1, 2019, the Basel III Rules will require the Company and Bank to maintain (i) a minimum ratio of common equity tier 1 capital to risk-weighted assets of at least 4.5%, plus a 2.5% capital conservation buffer, which effectively results in a minimum ratio of 7.0% upon full implementation, (ii) a minimum ratio of tier 1 capital to risk-weighted assets of at least 6.0%, plus a 2.5% capital conservation buffer, which effectively results in a minimum ratio of 8.50% upon full implementation, (iii) a minimum ratio of total capital to risk-weighted assets of at least 8.0%, plus a 2.5% capital conservation buffer, which effectively results in a minimum ratio of 10.5% upon full implementation and (iv) a minimum leverage ratio of 4.0%.

Gramm-Leach-Bliley Act. Under the Gramm-Leach-Bliley Act (the “GLBA”), a bank holding company that elects to become a “financial holding company” will be permitted to engage in any activity that the FRB, in consultation with the Secretary of the Treasury, determines by regulation or order is (i) financial in nature or incidental to such financial activity or (ii) complementary to a financial activity and does not pose a substantial risk to the safety and soundness of depository institutions or the financial system generally. In addition to traditional lending activities, the GLBA specifies the following activities as financial in nature:

· acting as principal, underwriter, agent or broker for insurance;

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

· merchant banking activities; and

· providing financial and investment advice.

A bank holding company may become a financial holding company only if all depository institution subsidiaries of the holding company are well-capitalized, well-managed and have at least a satisfactory rating under the CRA. A financial holding company that falls out of compliance with such requirement may be required to cease engaging in certain activities. In connection with the Company’s pending merger with Community & Southern Holdings, Inc. (“C&S”), the Company submitted a declaration to elect to become a financial holding company to the Federal Reserve Bank of St. Louis in December 2015.  We expect the Federal Reserve to act upon our election to be treated as a financial holding company at the same time it acts upon the bank holding company merger application filed in connection with the C&S merger. The Company made this election because the pending C&S merger involves the

15

acquisition of a captive insurance subsidiary. The Company does not currently intend to continue the operations of the captive insurance subsidiary and expects to dissolve the entity as soon as permissible after the consummation of the C&S merger.  As soon as the captive insurance subsidiary is dissolved and the Company winds up its operations, the Company intends to file the appropriate applications with the Federal Reserve requesting that it no longer be treated as a financial holding company.

The GLBA provides that state banks, such as the Bank, may invest in financial subsidiaries that engage as the principal in activities that would only be permissible for a national bank to conduct in a financial subsidiary. This authority is generally subject to the same conditions that apply to national bank investments in financial subsidiaries.

Under the consumer privacy provisions mandated by the GLBA, when establishing a customer relationship a financial institution must give the consumer certain privacy-related information, such as when the institution will disclose nonpublic, personal information to unaffiliated third parties, what type of information it may share and what types of affiliates may receive the information. The institution must also provide customers with annual privacy notices, a reasonable means for preventing the disclosure of information to third parties, and the opportunity to opt out of many features of the institution’s disclosure policies at any time.

Cybersecurity. State and federal banking regulators have issued various policy statements emphasizing the importance of technology risk management and supervision.  Such policy statements indicate that financial institutions should design multiple layers of security controls to establish lines of defense and to ensure that their risk management processes also address the risk posed by compromised customer credentials, including security measures to reliably authenticate customers accessing internet-based services of the financial institution. Such policy statements also indicate that a financial institution’s management is expected to maintain sufficient business continuity planning processes to ensure the rapid recovery, resumption and maintenance of the institution’s operations after a cyber-attack involving destructive malware. A financial institution is also expected to develop appropriate processes to enable recovery of data and business operations and address rebuilding network capabilities and restoring data if the institution or its critical service providers fall victim to this type of cyber-attack. If we fail to observe the regulatory guidance, we could be subject to various regulatory sanctions, including financial penalties.

In the ordinary course of business, we rely on electronic communications and information systems to conduct our operations and to store sensitive data. We employ an in-depth, layered, defensive approach that leverages people, processes and technology to manage and maintain cybersecurity controls. We employ a variety of preventative and detective tools to monitor, block, and provide alerts regarding suspicious activity, as well as to report on any suspected advanced persistent threats. Notwithstanding the strength of our defensive measures, the threat from cyber attacks is severe, attacks are sophisticated and increasing in volume, and attackers respond rapidly to changes in defensive measures. While to date, we have not experienced a significant compromise, significant data loss or any material financial losses related to cybersecurity attacks, our systems and those of our customers and third-party service providers are under constant threat and it is possible that we could experience a significant event in the future. Risks and exposures related to cybersecurity attacks are expected to remain high for the foreseeable future due to the rapidly evolving nature and sophistication of these threats, as well as due to the expanding use of Internet banking, mobile banking and other technology-based products and services by us and our customers. See Item 1A. Risk Factors for a further discussion of risks related to cybersecurity.

Community Reinvestment Act.  The CRA requires, in connection with examinations of financial institutions, that federal banking regulators evaluate the record of each financial institution in meeting the credit needs of its local community, including low and moderate-income neighborhoods, consistent with the safe and sound operations of the banks. Failure to adequately meet these criteria could impose additional requirements and limitations on us. These regulations also provide for regulatory assessment of a bank’s record in meeting the needs of its service area when considering applications to establish branches, merger applications and applications to acquire the assets and assume the liabilities of another bank.  In the case of a bank holding company, the CRA performance record of the banks involved in the transaction are reviewed in connection with the filing of an application to acquire ownership or control of shares or assets of a bank or to merge with any other bank holding company. An unsatisfactory record can substantially delay or block the transaction. Additionally, a bank must make available for public review, certain portions of its most recent CRA examination report conducted by its federal banking regulators.  

USA Patriot Act. The USA PATRIOT Act of 2001 (the “Patriot Act”) increased the obligations of financial institutions, including banks, to identify their customers, watch for and report suspicious transactions, respond to requests for information by federal banking regulatory authorities and law enforcement agencies, and share information with other financial institutions. The Patriot Act also amended the BHCA and Section 18(c) of the Federal Deposit Insurance Act (commonly referred to as the “Bank Merger Act”) to require federal banking regulatory authorities to consider the effectiveness of a financial institution’s anti-money laundering activities when reviewing an application to expand operations. Financial institutions, including banks, are required under final rules implementing Section 326 of the Patriot Act to establish procedures for collecting standard information from customers opening new accounts and verifying the identity of these new account holders within a reasonable period of time.  Failure of a financial institution to maintain and implement adequate programs to combat money laundering and terrorist financing, or to comply with all of the relevant laws or regulations, could have serious legal, economic and reputational consequences for the institution,

16

including causing applicable bank regulatory authorities not to approve merger or acquisition transactions when regulatory approval is required or to prohibit such transactions even if approval is not required.

Office of Foreign Assets Control Regulation. The United States has imposed economic sanctions that affect transactions with designated foreign countries, nationals and others which are administered by the Treasury’s Office of Foreign Assets Control. Failure to comply with these sanctions could have serious legal, economic and reputational consequences, including causing applicable bank regulatory authorities not to approve merger or acquisition transactions when regulatory approval is required or to prohibit such transactions even if approval is not required.

Enforcement Authority. The FRB has enforcement authority over bank holding companies and non-banking subsidiaries to forestall activities that represent unsafe or unsound practices or constitute violations of law. It may exercise these powers by issuing cease-and-desist orders or through other actions. The FRB may also assess civil penalties in amounts up to $1 million for each day’s violation against companies or individuals who violate the BHCA or related regulations. The FRB can also require a bank holding company to divest ownership or control of a non-banking subsidiary or require such subsidiary to terminate its non-banking activities. Certain violations may also result in criminal penalties. For purposes of enforcing the designated consumer financial protection laws, (i) the CFPB has primary enforcement authority over banks with total assets greater than $10 billion and their affiliates, and (ii) a bank’s primary federal regulator retains exclusive enforcement authority over banks with $10 billion or less in total assets and their affiliates. When we surpass this $10 billion asset threshold, we will be subject to examination by the CFPB with respect to our consumer products and services.

The FDIC possesses comparable enforcement authority under the Federal Deposit Insurance Act, the Federal Deposit Insurance Corporation Improvement Act of 1991 (the “FDICIA”) and other statutes with respect to the Bank. In addition, the FDIC can terminate insurance of accounts, after notice and hearing, upon a finding that the insured institution is or has engaged in any unsafe or unsound practice that has not been corrected, is in an unsafe and unsound condition, or has violated any applicable law, regulation, rule, or order of, or condition imposed by the appropriate supervisors.

The FDICIA required federal banking agencies to broaden the scope of regulatory corrective action taken with respect to depository institutions that do not meet minimum capital and related requirements and to take such actions promptly in order to minimize losses to the FDIC. In connection with FDICIA, federal banking agencies established capital measures (including both a leverage measure and a risk-based capital measure) and specified for each capital measure the levels at which depository institutions will be considered well-capitalized, adequately capitalized, undercapitalized, significantly undercapitalized or critically undercapitalized. If an institution becomes classified as undercapitalized, the appropriate federal banking agency will require the institution to submit an acceptable capital restoration plan and can suspend or greatly limit the institution’s ability to effect numerous actions including capital distributions, acquisitions of assets, the establishment of new branches and the entry into new lines of business. The capital restoration plan will not be accepted by the regulators unless each company having control of the undercapitalized institution guarantees the subsidiary’s compliance with the capital restoration plan up to a certain specified amount. Any such guarantee from a depository institution’s holding company is entitled to a priority of payment in bankruptcy.

The aggregate liability of the holding company of an undercapitalized bank is limited to the lesser of 5% of the institution’s assets at the time it became undercapitalized or the amount necessary to cause the institution to be “adequately capitalized.” The bank regulators have greater power in situations where an institution becomes “significantly” or “critically” undercapitalized or fails to submit a capital restoration plan. For example, a bank holding company controlling such an institution can be required to obtain prior FRB approval of proposed dividends, or might be required to consent to a consolidation or to divest the troubled institution or other affiliates.

Examination. The FRB may examine the Company and any or all of its subsidiaries. To assess compliance with the designated consumer financial protection laws, the Dodd-Frank Act gives the CFPB the authority to include its examiners, on a sampling basis, in examinations performed by primary federal regulators such as the FRB. The FDIC examines and evaluates insured banks approximately every 12 months, and it may assess the institution for its costs of conducting the examinations. The FDIC has a reciprocal agreement with the Arkansas State Bank Department whereby each will accept the other’s examination reports in certain cases. Our bank subsidiary generally undergoes FDIC and state examinations on a joint basis.

Reporting Obligations. As a bank holding company, we must file with the FRB an annual report and such additional information as the FRB may require pursuant to the BHCA. Our bank subsidiary must submit to federal and state regulators annual audit reports prepared by independent auditors. Our Annual Report on Form 10-K, which includes the report of our independent auditors, can be used to satisfy this requirement. Our bank subsidiary must submit quarterly, to the FDIC, a Call Report. Our bank holding company must submit quarterly, to the FRB, an FR Y-9C and an FR Y-9LP.  We also file various other required reports with federal and state regulators.

17

Other Consumer Laws and Regulations. Our status as a registered bank holding company under the BHCA does not exempt us from certain federal and state laws and regulations applicable to corporations generally, including, without limitation, certain provisions of the federal securities laws. We are subject to the jurisdiction of the SEC and of state securities regulatory authorities for matters relating to the offer and sale of our securities.

Our loan operations are subject to certain federal laws applicable to credit transactions, including, among others:

· the TILA, which governs disclosures of credit terms and costs to consumer borrowers, gives consumers the right to cancel certain credit transactions, and defines requirements for servicing consumer loans secured by a dwelling;

· the Home Mortgage Disclosure Act of 1975, which requires financial institutions to provide information to enable the public and public officials to determine whether a financial institution is fulfilling its obligation to help meet the housing needs of the communities it serves;

· the Equal Credit Opportunity Act, which prohibits discrimination on the basis of race, creed or other prohibited factors in extending credit;

· the Fair Credit Reporting Act of 1978 (the “FCRA”), which governs the use and provision of information to credit reporting agencies;

· the Home Ownership and Equity Protection Act, which regulates the terms and disclosures of certain closed end home mortgage loans that are not purchase money loans and includes loans classified as “high cost loans;”

· the Electronic Fund Transfer Act, which regulates fees and other terms of electronic funds transactions;

· the Fair and Accurate Credit Transactions Act of 2003, which permanently extended the national credit reporting standards of the FCRA, and permits consumers, including our customers, to opt out of information sharing among affiliated companies for marketing purposes and requires financial institutions, including banks, to notify a customer if the institution provides negative information about the customer to a national credit reporting agency or if the credit that is granted to the customer is on less favorable terms than those generally available;

· the Fair Debt Collection Practices Act, which governs the manner in which consumer debts may be collected by collection agencies;

· the Fair Housing Act, which prohibits discriminatory practices relative to real estate related transactions, including the financing of housing and the rules and regulations of the various federal agencies charged with the responsibility of implementing such federal laws; and

· the Real Estate Settlement and Procedures Act of 1974, which affords consumers greater protection pertaining to federally related mortgage loans by requiring, among other things, improved and streamlined good faith estimate forms including clear summary information and improved disclosure of yield spread premiums.

Our loan operations are also subject to the many requirements governing mortgages and lending practices set forth in the Dodd-Frank Act discussed above.

Our deposit operations are subject to several laws, including but not limited to:

· the Right to Financial Privacy Act of 1978, which imposes a duty to maintain confidentiality of consumer financial records and prescribes procedures for complying with administrative subpoenas of financial records;

· the Electronic Funds Transfer Act, which governs automatic deposits to and withdrawals from deposit accounts and customers’ rights and liabilities arising from the use of automated teller machines and other electronic banking services;

· the Truth in Savings Act, which requires depository institutions to disclose the terms of deposit accounts to consumers;

· the Expedited Funds Availability Act, which requires financial institutions to make deposited funds available according to specified time schedules and to disclose funds availability policies to consumers; and

· the Check Clearing for the 21st Century Act (“Check 21”), which is designed to foster innovation in the payments system and to enhance its efficiency by reducing some of the legal impediments to check truncation. Check 21 created a

18

new negotiable instrument called a substitute check and permits, but does not require, banks to truncate original checks, process check information electronically, and deliver substitute checks to banks that wish to continue receiving paper checks.  

The consumer protection provisions of the Dodd-Frank Act and the examination, supervision and enforcement of those laws and implementing regulations by the CFPB have created a more intense and complex environment for consumer finance regulation. The CFPB has significant authority to implement and enforce federal consumer finance laws, including the Truth in Lending Act, the Equal Credit Opportunity Act and new requirements for financial services products provided for in the Dodd-Frank Act, as well as the authority to identify and prohibit unfair, deceptive or abusive acts and practices. The review of products and practices to prevent such acts and practices is a continuing focus of the CFPB, and of banking regulators more broadly. The ultimate impact of this heightened scrutiny is uncertain but could result in changes to pricing, practices, products and procedures. It could also result in increased costs related to regulatory oversight, supervision and examination, additional remediation efforts and possible penalties. In addition, the Dodd-Frank Act provides the CFPB with broad supervisory, examination and enforcement authority over various consumer financial products and services, including the ability to require reimbursements and other payments to customers for alleged legal violations and to impose significant penalties, as well as injunctive relief that prohibits lenders from engaging in allegedly unlawful practices. The CFPB also has the authority to obtain cease and desist orders providing for affirmative relief or monetary penalties. The Dodd-Frank Act does not prevent states from adopting stricter consumer protection standards. State regulation of financial products and potential enforcement actions could also adversely affect our business, financial condition or results of operations.

State Regulation

We are subject to examination and regulation by the Arkansas State Bank Department. Examinations of our bank subsidiary are typically conducted annually but may be extended to 24 months if an interim examination is performed by the FDIC. The Arkansas State Bank Department may also examine the activities of our bank holding company in conjunction with its examination of our bank subsidiary or in conjunction with the FRB’s examination of our bank holding company. The extent of such examination will depend upon the complexity and level of debt owed by our bank holding company, and other various criteria as determined by the Arkansas State Bank Department.  We are also required to submit certain reports filed with the FRB to the Arkansas State Bank Department.

Under the Arkansas Banking Code of 1997, the acquisition of more than 25% of any class of the outstanding capital stock of any bank located in Arkansas requires approval of the Arkansas State Bank Commissioner (the “Bank Commissioner”). Additionally, a bank holding company may not acquire any bank if after such acquisition the holding company would control, directly or indirectly, banks having 25% of the total bank deposits (excluding deposits from other banks and public funds) in the State of Arkansas. A bank holding company also cannot own more than one bank subsidiary if any of its bank subsidiaries has been chartered for less than five years.

The Bank Commissioner has the authority, with the consent of the Governor of the State of Arkansas, to declare a state of emergency and temporarily modify or suspend banking laws and regulations in communities where such a state of emergency exists. The Bank Commissioner may also authorize a bank to close its offices and any day when such bank offices are closed will be treated as a legal holiday, and any director, officer or employee of such bank shall not incur any liability related to such emergency closing.  To date no such state of emergency has been declared to exist by the Bank Commissioner.

Restrictions on Bank Subsidiary

Lending Limits. The lending and investment authority of our subsidiary bank is derived from Arkansas law. The lending power is generally subject to certain restrictions, including the amount which may be lent to a single borrower.  Under Arkansas law, the obligations of one borrower to a bank may not exceed 20% of the bank’s capital base. See also Note 19 to our Consolidated Financial Statements included elsewhere in this Annual Report on Form 10-K for a discussion of lending limits.

Reserve Requirements. Arkansas law requires state chartered banks to maintain such reserves as are required by the applicable federal regulatory agency. Federal banking laws require all insured banks to maintain reserves against their checking and transaction accounts (primarily checking accounts, NOW and Super NOW checking accounts). Because reserves must generally be maintained in cash, non-interest bearing accounts or in accounts that earn only a nominal amount of interest, the effect of the reserve requirements is to increase our cost of funds.

Payment of Dividends.  Regulations of the FDIC and the Arkansas State Bank Department limit the ability of our bank subsidiary to pay dividends to our bank holding company without the prior approval of such agencies.  FDIC regulations prevent insured state banks from paying any dividends from capital and allow the payment of dividends only from net profits then on hand after deduction for losses and bad debts. The Arkansas State Bank Department currently limits the amount of dividends that our bank subsidiary can pay our bank holding company to 75% of its net profits after taxes for the current year plus 75% of its retained net profits after taxes for the immediately preceding year.

19

Restrictions on Transactions with Affiliates.  Federal law substantially restricts transactions between financial institutions and their affiliates, particularly their non-financial institution affiliates. As a result, our bank subsidiary is sharply limited in making extensions of credit to our bank holding company or any non-bank subsidiary, in investing in the stock or other securities of our bank holding company or any non-bank subsidiary, in buying the assets of, or selling assets to, our bank holding company and/or in taking such stock or securities as collateral for loans to any borrower. Our bank subsidiary is subject to Section 23A of the Federal Reserve Act, which places limits on the amount of loans or extensions of credit to, or investments in, or certain other transactions with, affiliates, including our bank holding company. In addition, limits are placed on the amount of advances to third parties collateralized by the securities or obligations of affiliates. Most of these loans and certain other transactions must be secured in prescribed amounts. Our bank subsidiary is also subject to Section 23B of the Federal Reserve Act, which prohibits an institution from engaging in transactions with certain affiliates unless the transactions are on terms substantially the same, or at least as favorable to such institution or its subsidiaries, as those prevailing at the time for comparable transactions with non-affiliated companies. Our bank subsidiary is subject to restrictions on extensions of credit to executive officers, directors, certain principal shareholders, and their related interests. These extensions of credit (1) 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 (2) must not involve more than the normal risk of repayment or present other unfavorable features.

Effect of Governmental Monetary Policies

Our earnings are affected by domestic economic conditions and the monetary and fiscal policies of the U.S. government and its agencies. The FRB’s monetary policies have had, and are likely to continue to have, an important impact on the operating results of commercial banks through the FRB’s statutory power to implement national monetary policy in order, among other things, to curb inflation or combat a recession. The FRB, through its monetary and fiscal policies, affects the levels of bank loans, investments and deposits through its control over the issuance of U.S. government securities, its regulation of the discount rate applicable to member banks and its influence over reserve requirements to which member banks are subject. We cannot predict the nature or impact of future changes in monetary and fiscal policies.

Future Regulation of Bank Holding Companies and Banks

Certain proposals affecting the banking industry have been discussed from time to time. Such proposals have included, but are not limited to, the following: regulation of all insured depository institutions by a single “super” federal regulator; limitations on the number of accounts protected by the DIF and further modification of the coverage limit on deposits. During 2016, numerous regulatory agencies will continue to promulgate rules and regulations to implement the Dodd-Frank Act. The ultimate impact of the Dodd-Frank Act on our business and results of operations will depend on regulatory interpretation and rulemaking, as well as the success of any actions taken to mitigate the negative earnings impact of certain provisions. We cannot predict whether or in what form any proposed regulation or statute will be adopted or the extent to which its business may be affected by any new regulation or statute.

Item 1A. RISK FACTORS

An investment in shares of our common stock involves certain risks. The following risks and other information in this report or incorporated in this report by reference, including our Consolidated Financial Statements and related notes and “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” should be carefully considered before investing in shares of our common stock. These risks may adversely affect our financial condition, results of operations or liquidity. Many of these risks are out of our direct control, though efforts are made to manage those risks while optimizing financial results. These risks are not the only ones we face. Additional risks and uncertainties that we are not aware of or focused on or that we currently deem immaterial may also adversely affect our business and operation. This Annual Report on Form 10-K is qualified in its entirety by all these risk factors.

RISKS RELATED TO OUR BUSINESS

Our profitability is dependent on our banking activities.

Because we are a bank holding company, our profitability is directly attributable to the success of our bank subsidiary. Our banking activities compete with other banking institutions on the basis of products, service, convenience and price. Due in part to both regulatory changes and consumer demands, banks have experienced increased competition from other entities offering similar products and services. We rely on the profitability of our bank subsidiary and dividends received from our bank subsidiary for payment of our operating expenses, satisfaction of our obligations and payment of dividends on shares of our common stock. As is the case with other similarly situated financial institutions, our profitability will be subject to the fluctuating cost and availability of funds, changes in the prime lending rate and other interest rates, changes in economic conditions in general, and other factors.

We depend on key personnel for our success.

Our operating results and ability to adequately manage our growth and minimize loan and lease losses are highly dependent on the services, managerial abilities and performance of our current executive officers and other key personnel. We have an experienced management team that our board of directors believes is capable of managing and growing our business. We do not have employment contracts with our executive officers and, except in limited cases pursuant to recent acquisitions, key personnel. Losses of or changes in our current executive officers or other key personnel and their responsibilities may disrupt our business and could adversely affect our financial condition, results of operations and liquidity. Additionally, our ability to retain our current executive officers and other key personnel may be further impacted by existing and proposed legislation and regulations regarding incentive compensation that is affecting the financial services industry. There can be no assurance that we will be successful in retaining our current executive officers or other key personnel, or hiring additional key personnel to assist in executing our growth, expansion and acquisition strategies.

Our operations are significantly affected by interest rate levels.

Our profitability is dependent to a large extent on net interest income, which is the difference between interest income earned on loans, leases and investment securities and interest expense paid on deposits, other borrowings and subordinated debentures. Our business is affected by changes in general interest rate levels and changes in the differential between short-term and long-term interest rates, both of which are beyond our control. An increase in market interest rates on loans is generally associated with a lower volume of loan originations, which may reduce earnings. Following an increase in the general level of interest rates, our ability to maintain a positive net interest spread is dependent on our ability to increase our loan and lease offering rates, replace loan and lease maturities with new originations, minimize increases on our deposit rates, and maintain an acceptable level and mix of funding. Although we have implemented procedures we believe will reduce the potential effects of changes in interest rates on our net interest income, these procedures may not always be successful. Accordingly, changes in levels of market interest rates could materially and adversely affect our net interest income and our net interest margin, asset quality, loan and lease origination volume, liquidity, and overall profitability. We cannot assure you that we can minimize our interest rate risk.

We rely primarily on an earnings simulation model to analyze our interest rate risk and our sensitivity to interest rate changes.  This earnings simulation model projects a baseline net interest income and estimated changes to such baseline from changes in interest rates and incorporates a number of assumptions, including, among others, (i) the expected exercise of call features on various assets and liabilities, (ii) the expected rates at which rate sensitive assets and rate sensitive liabilities will reprice, (iii) the expected growth in various interest earning assets and interest bearing liabilities and the expected interest rates on such new assets and liabilities, (iv) the expected relative movements in different interest rate indices which are used as the basis for pricing or repricing various assets and liabilities, (v) existing and expected contractual ceiling or floor rates on various assets and liabilities, and (vi) expected changes in administered rates on interest bearing transaction, savings, money market and time deposit accounts and the expected impact of competition on the pricing or repricing of such accounts.  These assumptions and inputs into our interest simulation model are difficult to predict.  Should these assumptions prove to be inaccurate, our interest simulation model results may not accurately project our interest rate risk and our sensitivity to interest rate changes.  As a result, we may incur increased or unexpected losses due to changes in interest rates which could materially and adversely affect our net interest income, our net interest margin and our results of operations.

The fiscal and monetary policies of the federal government and its agencies could have a material adverse effect on our earnings.

The FRB regulates the supply of money and credit in the U.S. Its policies determine in large part the cost of funds for lending and investing and the return earned on those loans and investments, both of which may affect our net interest income and net interest margin. Changes in the supply of money and credit can also materially decrease the value of financial assets we hold, such as debt

21

securities. The FRB’s policies can also adversely affect borrowers, potentially increasing the risk that they may fail to repay their loans and leases. Changes in such policies are beyond our control and difficult to predict; consequently, the effect of these changes on our activities and results of operations is difficult to predict.

Our business depends on the condition of the local and regional economies where we operate.

A large number of our banking offices are located in south central and southeastern portions of the United States. As a result, our financial condition and results of operations may be significantly impacted by changes in the economies of the south central and southeastern states where we currently have most of our banking offices. Slowdown in economic activity in these areas, including deterioration in housing markets or increases in unemployment and under-employment, may have a significant and disproportionate effect on consumer and business confidence and the demand for our products and services, result in an increase in non-payment of loans and leases and a decrease in collateral value, and significantly affect our deposit funding sources. Any of these events could have an adverse effect on our financial position, results of operations and liquidity.

Our business may suffer if there are significant declines in the value of real estate.

The market value of real estate can fluctuate significantly in a short period of time as a result of market conditions in the geographic area in which the real estate is located. If the value of the real estate serving as collateral for our loan and lease portfolio were to decline materially, a significant part of our loan portfolio could become under-collateralized. If the loans that are collateralized by real estate become troubled during a time when market conditions are declining or have declined, we may not be able to realize the value of the security anticipated when we originated the loan, which in turn could have an adverse effect on our allowance and provision for loan and lease losses and our financial condition, results of operations and liquidity.

Most of our foreclosed assets are comprised of real estate properties. We carry these properties at their estimated fair values less estimated selling costs. While we believe the carrying values for such assets are reasonable and appropriately reflect current market conditions, there can be no assurance that the values of such assets will not further decline prior to sale or that the amount of proceeds realized upon disposition of foreclosed assets will approximate the carrying value of such assets. If the proceeds from any such dispositions are less than the carrying value of foreclosed assets, we will record a loss on the disposition of such assets, which in turn could have an adverse effect on our results of operations.

We are subject to environmental liability risks.

A significant portion of our loan and lease portfolio is secured by real property. In the ordinary course of business, we may foreclose on and take title to real properties securing certain loans. In doing so, there is a risk that hazardous or toxic substances could be found on these properties. Additionally, we have acquired a number of retail banking facilities and other real properties as a result of acquisitions, any of which may contain hazardous or toxic substances.  If hazardous or toxic substances are found, we may be liable for remediation costs, as well as for personal injury and property damage. Environmental laws may require us to incur substantial expenses and may materially reduce the affected property’s value or limit our ability to use or sell the affected property. In addition, future laws or more stringent interpretations or enforcement policies with respect to existing laws may increase our exposure to environmental liability. We have policies and procedures that require either formal or informal evaluation of environmental risks and liabilities on real property (i) before originating any loan or foreclosure action, except for (a) loans originated for sale in the secondary market secured by 1-4 family residential properties and (b) certain loans where the real estate collateral is second lien collateral or (ii) prior to the completion of any acquisition of retail banking facilities, real property for future development of retail banking facilities or any other real property, including any real property to be acquired in a merger and acquisition transaction. These policies, procedures and evaluations may not be sufficient to detect all potential environmental hazards. The remediation costs and any other financial liabilities associated with an environmental hazard could have an adverse effect on our financial condition, results of operations and liquidity.

If we do not properly manage our credit risk, our business could be seriously harmed.

There are substantial risks inherent in making any loan or lease, including, but not limited to –

· risks resulting from changes in economic and industry conditions;

· risks inherent in dealing with individual borrowers;

· risks inherent from uncertainties as to the future value of collateral; and

· the risk of non-payment of loans and leases.

22

Although we attempt to minimize our credit risk through prudent loan and lease underwriting procedures and by monitoring concentrations of our loans and leases, there can be no assurance that these underwriting and monitoring procedures will reduce these risks. Moreover, as we continue to expand into new markets, credit administration and loan and lease underwriting policies and procedures may need to be adapted to local conditions.  The inability to properly manage our credit risk or appropriately adapt our credit administration and loan and lease underwriting policies and procedures to local market conditions or changing economic circumstances could have an adverse effect on our allowance and provision for loan and lease losses and our financial condition, results of operations and liquidity.

We make and hold a significant number of construction/land development, non-farm/non-residential and other real estate loans in our loan and lease portfolio.

Our loan and lease portfolio is comprised of a significant amount of real estate loans, including a large number of construction/land development and non-farm/non-residential loans.  Our real estate loans comprised 89.2% of our total loans and leases at December 31, 2015.  In addition, our construction/land development and non-farm/non-residential loans, which are subsets of our real estate loans, comprised 34.5% and 37.8%, respectively, of our total loan and lease portfolio at December 31, 2015. Real estate loans, including construction/land development and non-farm/non-residential loans, pose different risks than do other types of loan and lease categories. In particular, real estate construction, acquisition and development loans have certain risks not present in other types of loans, including, among others, risks associated with construction cost overruns, project completion risk, general contractor credit risk and risks associated with the ultimate sale, lease or use of the completed construction. If a decline in economic conditions or other issues cause difficulties for our borrowers of these types of loans, if we fail to evaluate the credit of these loans accurately when we underwrite them or if we do not continue to adequately monitor the performance of these loans, our lending portfolio could experience delinquencies, defaults and credit losses that could have a material adverse effect on our business, financial condition or results of operations.  We believe we have established appropriate underwriting procedures for our real estate loans, including construction/land development and non-farm/non-residential loans, and have established appropriate allowances for loan and lease losses to cover the credit risk associated with such loans. However, there can be no assurance that such underwriting procedures are, or will continue to be, appropriate or that losses on real estate loans, including construction/land development and non-farm/non-residential loans, will not require additions to our allowance for loan and lease losses, which could have an adverse effect on our financial position, results of operations or liquidity.

We could experience deficiencies in our allowance for loan and lease losses.

We maintain an allowance for loan and lease losses, established through a provision for loan and lease losses charged to expense, that represents our best estimate of probable losses inherent in our existing loan and lease portfolio. Although we believe that we maintain our allowance for loan and lease losses at a level adequate to absorb losses in our loan and lease portfolio, estimates of loan and lease losses are subjective and their accuracy may depend on the outcome of future events. Our experience in the banking industry indicates that some portion of our loans and leases may only be partially repaid or may never be repaid at all. Loan and lease losses occur for many reasons beyond our control. Accordingly, we may be required to make significant and unanticipated increases in our allowance for loan and lease losses during future periods which could materially affect our financial position, results of operations and liquidity. Additionally, bank regulatory authorities, as an integral part of their supervisory functions, periodically review our allowance for loan and lease losses. These regulatory authorities may require adjustments to the allowance for loan and lease losses or may require recognition of additional loan and lease losses or charge-offs based upon their judgment. Any increase in the allowance for loan and lease losses or charge-offs required by bank regulatory authorities could have an adverse effect on our financial condition, results of operations and liquidity. See also Recently Issued Accounting Pronouncements included in Note 1 to the Consolidated Financial Statements, found elsewhere in this Annual Report on Form 10-K, for a discussion of proposed changes to how entities measure and recognize credit impairment, including the effect on the allowance for loan and lease losses.

The performance of our investment securities portfolio is subject to fluctuation due to changes in interest rates and market conditions, including credit deterioration of the issuers of individual securities.

Changes in interest rates can negatively affect the performance of most of our investment securities. Interest rate volatility can reduce unrealized gains or increase unrealized losses in our portfolio. Interest rates are highly sensitive to many factors including monetary policies, domestic and international economic and political issues, and other factors beyond our control. Fluctuations in interest rates can materially affect both the returns on and market value of our investment securities. Additionally, actual investment income and cash flows from investment securities that carry prepayment risk, such as mortgage-backed securities and callable securities, may materially differ from those anticipated at the time of investment or subsequently as a result of changes in interest rates and market conditions.

23

Our investment securities portfolio consists of a number of securities whose trading markets are “not active.” As a result, we utilize alternative methodologies for pricing these securities that include various estimates and assumptions. There can be no assurance that we can sell these investment securities at the price derived by these methodologies, or that we can sell these investment securities at all, which could have an adverse effect on our financial position, results of operation or liquidity.

We monitor the financial position of the various issues of investment securities in our portfolio, including each of the state and local governments and other political subdivisions where we have exposure. To the extent we have securities in our portfolio from issuers who have experienced a deterioration of financial condition, or who may experience future deterioration of financial condition, the value of such securities may decline and could result in an other-than-temporary impairment charge, which could have an adverse effect on our financial condition, results of operations and liquidity.

Our recent results may not be indicative of our future results.

We may not be able to grow our business at the same rate of growth achieved in recent years or even grow our business at all. Additionally, in the future we may not have the benefit of several factors that have been favorable to our business in past years, such as an interest rate environment where changes in rates occur at a relatively orderly and modest pace, the ability to find suitable expansion opportunities, or otherwise to capitalize on opportunities presented by economic turbulence, or other factors and conditions. Numerous factors, such as weakening or deteriorating economic conditions, regulatory and legislative considerations, and competition may impede or restrict our ability to expand our market presence and could adversely affect our future operating results.

Our FDIC insurance premiums may increase.

The FDIC has increased premiums charged to all financial institutions for FDIC insurance protection during recent years and such premiums may increase further in future years. We have historically paid at or near the lowest applicable premium rate under the FDIC’s insurance premium rate structure due to our sound financial position. However, should bank failures increase in the future, FDIC insurance premiums may also increase. Additionally, when we exceed $10 billion in assets, the method for calculating our FDIC assessments will change, and we expect our FDIC insurance premiums will increase as a result. Future increases of FDIC insurance premiums or special assessments could have a material adverse effect on our business, financial condition or results of operations.

To successfully implement our growth strategy, we must expand our operations in both new and existing markets.

We intend to continue the expansion and development of our business by pursuing our growth and de novo branching strategy. Accordingly, our growth prospects must be considered in light of the risks, expenses and difficulties frequently encountered by banking companies pursuing growth strategies. In order to successfully execute our growth strategy, we must, among other things:

· identify and expand into suitable markets;

· obtain regulatory and other approvals;

· identify and acquire suitable sites for new banking offices;

· attract and retain qualified bank management and staff;

· build a substantial customer base;

· expand our loan portfolio while maintaining credit quality;

· attract sufficient deposits and capital to fund anticipated loan and lease growth;

· maintain adequate common equity and regulatory capital; and

· maintain sufficient qualified staffing and infrastructure to support growth and compliance with increasing regulatory requirements.

In addition to the foregoing factors, there are considerable costs involved in opening banking offices, and such new offices generally do not generate sufficient revenues to offset their costs until they have been in operation for some time. Therefore, any new banking offices we open can be expected to negatively affect our operating results until those offices reach a size at which they become profitable. We could also experience an increase in expenses if we encounter delays in opening any new banking offices. Moreover, we cannot give any assurances that any new banking offices we open will be successful, even after they have become established, or that we can hire and retain qualified bank management and staff to achieve our growth and profitability goals. If we do not manage our growth effectively, our business, future prospects, financial condition, results of operations and liquidity could be adversely affected.

24

We may not be able to meet the cash flow requirements of our depositors or the cash needs for expansion and other corporate activities.

Liquidity represents an institution’s ability to provide funds to satisfy demands from depositors, borrowers and other creditors by either converting assets into cash or accessing new or existing sources of incremental funds. Liquidity risk arises from the possibility that we may be unable to satisfy current or future funding requirements and needs. Our ALCO and Investments Committee (“ALCO”), which reports to the board of directors, has primary responsibility for oversight of our liquidity, funds management, asset/liability (interest rate risk) position and investment portfolio functions.

The objective of managing liquidity risk is to ensure that our cash flow requirements resulting from depositor, borrower and other creditor demands are met, as well as our operating cash needs, and that our cost of funding such requirements and needs is reasonable. We maintain a comprehensive interest rate risk, liquidity and funds management policy and a contingency funding plan that, among other things, include policies and procedures for managing liquidity risk.  Generally we rely on deposits, repayments of loans and leases and cash flows from our investment securities as our primary sources of funds. Our principal deposit sources include consumer, commercial and public funds customers in our markets. We have used these funds, together with wholesale deposit sources such as brokered deposits, along with Federal Home Loan Bank of Dallas (“FHLB”) advances, FRB borrowings, federal funds purchased and other sources of short-term borrowings, to make loans and leases, acquire investment securities and other assets and to fund continuing operations.

Deposit levels may be affected by a number of factors, including rates paid by competitors, general interest rate levels, returns available to customers on alternative investments, general economic and market conditions and other factors. Repayments of loans and leases are a relatively stable source of funds but are subject to the borrowers’ and lessees’ ability to repay loans and leases, which can be adversely affected by a number of factors including changes in general economic conditions, adverse trends or events affecting business industry groups or specific businesses, declines in real estate values or markets, business closings or lay-offs, inclement weather, natural disasters and other factors. Furthermore, loans and leases generally are not readily convertible to cash. Accordingly, we may be required from time to time to rely on secondary sources of liquidity to meet our loan, lease and deposit withdrawal demands or otherwise fund operations. Such secondary sources include FHLB advances, brokered deposits, secured and unsecured federal funds lines of credit from correspondent banks, FRB borrowings and/or accessing the capital markets.  

We anticipate we will continue to rely primarily on deposits, repayments of loans and leases, and cash flows from our investment securities to provide liquidity. Additionally, where necessary, the secondary sources of borrowed funds described above will be used to augment our primary funding sources. If we are unable to access any of these secondary funding sources when needed, we might be unable to meet our customers’ or creditors’ needs, which would adversely affect our financial condition, results of operations, and liquidity.

We may need to raise additional capital in the future to continue to grow, but that capital may not be available when needed.

Federal and state bank regulators require us, and our bank subsidiary, to maintain adequate levels of capital to support operations. At December 31, 2015, our bank holding company and our bank subsidiary regulatory capital ratios were at “well-capitalized” levels under regulatory guidelines. However, our business strategy calls for continued growth in our existing banking markets (through currently operating offices, opening additional offices and making additional acquisitions) and to expand into new markets as appropriate opportunities arise.  Growth in assets at rates in excess of the rate at which our capital is increased through retained earnings will reduce our capital ratios unless we continue to increase capital. If our capital ratios fell below “well-capitalized” levels, the FDIC insurance assessment rate would increase until capital is restored and maintained at a “well-capitalized” level.  Additionally, should our capital ratios fall below “well-capitalized” levels, certain funding sources could become more costly or could cease to be available to us until such time as capital is restored and maintained at a “well-capitalized” level.  A higher assessment rate resulting in an increase in FDIC insurance premiums, increased cost of funding or loss of funding sources could have an adverse effect on our financial condition, results of operations and liquidity.

We may need to raise additional capital in the future to provide us with sufficient capital resources and liquidity to meet our commitments and business needs. As a publicly traded company, a likely source of additional funds is the capital markets, accomplished generally through the issuance of equity, including common stock, preferred stock, warrants, depository shares, stock purchase contracts or stock purchase units, and the issuance of senior debt or subordinated debentures. Our ability to raise additional capital, including senior debt or subordinated debentures, if needed, will depend, among other things, on conditions in the equity and/or debt markets at that time, which are outside of our control, and our financial performance.

We cannot assure you that access to such capital and liquidity will be available to us on acceptable terms or at all. Any occurrence that may limit our access to the capital markets, such as a decline in the confidence of debt purchasers, depositors of our bank subsidiary or counterparties participating in the capital markets, may materially and adversely affect our capital costs and our

25

ability to raise capital and/or debt and, in turn, our liquidity. If we cannot raise additional capital when needed, our ability to expand through internal growth or acquisitions or to continue operations could be impaired.

We may be adversely affected by risks associated with completed, pending or any potential future acquisitions.

We plan to continue to grow our business organically. However, we have pursued and expect to pursue additional acquisition opportunities in the future that we believe support our business strategy and may enhance our profitability. Acquisitions involve numerous risks, including, among others:

· incurring time and expense associated with identifying and evaluating potential acquisitions and negotiating potential transactions, resulting in our attention being diverted from the operation of our existing business;  

· using inaccurate estimates and judgments to evaluate credit, operations, management and market risks with respect to the target institution or assets;  

· the risk that the acquired business will not perform to our expectations;  

· difficulties, inefficiencies or cost overruns in integrating and assimilating the organizational cultures, operations, technologies, services and products of the acquired business with ours;  

· the risk of key vendors not fulfilling our expectations or not accurately converting data;  

· entering geographic and product markets in which we have limited or no direct prior experience;  

· the potential loss of key employees, vendors, customers and deposits of acquired banks;  

· the potential for liabilities and claims arising out of the acquired businesses; and  

· the risk of not receiving required regulatory approvals or such approvals being restrictively conditional.  

Acquisitions of financial institutions also involve operational risks and uncertainties, and acquired companies may have unknown or contingent liabilities with no corresponding accounting allowance, exposure to unexpected asset quality problems that require write downs or write-offs (as well as restructuring and impairment or other charges), difficulty retaining key employees and customers and other issues that could negatively affect our business. We may not be able to realize any projected cost savings, synergies or other benefits associated with any such acquisition we complete. Acquisitions may involve the payment of a premium over book and market values and, therefore, some dilution of our tangible book value and net income per common share may occur in connection with any future acquisition. Failure to successfully integrate the entities we acquire into our existing operations could increase our operating costs significantly and have a material adverse effect on our business, financial condition and results of operations.

We must generally satisfy a number of meaningful conditions prior to completing any acquisition, including, in certain cases, federal and state regulatory approval. Bank regulators consider a number of factors when determining whether to approve a proposed transaction, including the effect of the transaction on financial stability and the ratings and compliance history of all institutions involved, including the CRA, examination results and anti-money laundering and Bank Secrecy Act compliance records of all institutions involved. The process for obtaining required regulatory approvals has become substantially more difficult as a result of the financial crisis, which could affect our future business. We may fail to pursue, evaluate or complete strategic and competitively significant business opportunities as a result of our inability, or our perceived inability, to obtain any required regulatory approvals in a timely manner or at all.

In addition, we face significant competition from numerous other financial services institutions, many of which will have greater financial resources than we do, when considering acquisition opportunities. Accordingly, attractive acquisition opportunities may not be available to us. There can be no assurance that we will be successful in identifying or completing our pending or any potential future acquisitions.

Systems conversions of acquired banks may be difficult.

After we acquire a financial institution, the various operating systems must be converted, in most cases, to our operating systems. These systems conversions require personnel with unique and specialized skills and require a significant amount of planning, coordination and effort of internal resources and third-party vendors. Our inability to hire or retain individuals with the appropriate skills or to effectively plan, coordinate and manage these systems conversions or any failure to effectively implement these systems conversions could have serious negative customer impact, exposing us to reputational risk and adversely affecting our financial condition, results of operations and liquidity.

26

We face strong competition in our markets.

Competition in many of our banking markets is intense. We compete with other financial and bank holding companies, state and national commercial banks, savings and loan associations, consumer finance companies, credit unions, securities brokerages, insurance companies, mortgage banking companies, leasing companies, money market mutual funds, asset-based non-bank lenders and other financial institutions and intermediaries, as well as non-financial institutions offering payroll, debit card and other services. Many of these competitors have an advantage over us through substantially greater financial resources, lending limits and larger distribution networks, and are able to offer a broader range of products and services. Other competitors, many of which are smaller, are privately-held and thus benefit from greater flexibility in adopting or modifying growth or operational strategies than we do. If we fail to compete effectively for deposits, loans, leases and other banking customers in our markets, we could lose substantial market share, suffer a slower growth rate or no growth and our financial condition, results of operations and liquidity could be adversely affected.

The soundness of other financial institutions could adversely affect us.

Our ability to engage in routine funding transactions could be adversely affected by the actions and financial stability of other financial institutions. Financial services institutions are interrelated as a result of trading, clearing, counterparty or other relationships. We have exposure to various counterparties, including brokers and dealers, commercial and correspondent banks, and others. As a result, defaults by, or rumors or questions about, one or more financial services institutions, or the financial services industry generally, may result in market-wide liquidity problems and could lead to losses or defaults by such other institutions. Such occurrences could expose us to credit risk in the event of default of one or more counterparties and could have a material adverse effect on our financial position, results of operations and liquidity.

We depend on the accuracy and completeness of information about customers.

In deciding whether to extend credit or enter into certain transactions, we rely on information furnished by or on behalf of customers, including financial statements, credit reports, tax returns and other financial information. We may also rely on representations of those customers or other third parties, such as independent auditors, as to the accuracy and completeness of that information. Reliance on inaccurate or misleading financial statements, credit reports, tax returns or other financial information could have an adverse effect on our business, financial condition and results of operations.

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 financial health could damage our reputation, leading to difficulties in generating and maintaining accounts as well as in financing them. Adverse developments or other external perceptions regarding the practices of competitors, or the industry as a whole, may also adversely impact our reputation. In addition, adverse reputational effects on third parties with whom we have important relationships may also adversely affect our reputation. Adverse effects on our reputation, or the reputation of the 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 effects or events may also increase litigation risk. Any of these factors could have an adverse effect on our ability to achieve our business objectives and/or results of operations.

We may be subject to claims and litigation pertaining to fiduciary responsibility.

From time to time as part of our normal course of business, customers may make claims and take legal action against us based on actions or inactions related to the fiduciary responsibilities of our bank subsidiary’s Trust and Wealth Management Division. If such claims and legal actions are not resolved in a manner favorable to us, they may result in financial liability and/or adversely affect our market perception or our products and services. Any financial liability or reputation damage could have a material adverse effect on our business, which, in turn, could have a material adverse effect on our financial condition and results of operations.

We may be subject to claims and litigation asserting lender liability.

From time to time, and particularly during periods of economic stress, customers, including real estate developers, may make claims or otherwise take legal action pertaining to performance of our responsibilities. These claims are often referred to as “lender liability” claims and are sometimes brought in an effort to produce or increase leverage against us in workout negotiations or debt collection proceedings. Lender liability claims frequently assert one or more of the following allegations: breach of fiduciary duties, fraud, economic duress, breach of contract, breach of the implied covenant of good faith and fair dealing, and similar claims. Whether customer claims and legal action related to the performance of our responsibilities are founded or unfounded, if such claims and legal

27

actions are not resolved in a favorable manner, they may result in significant financial liability and/or adversely affect our market perception, products and services, as well as potentially affecting customer demand for those products and services. Any financial liability or reputation damage could have a material adverse effect on our business, which, in turn, could have a material adverse effect on our financial condition, results of operations and liquidity.

We need to stay current on technological changes in order to compete and meet customer demands.

The financial services industry is undergoing rapid technological changes with frequent introductions of new technology-driven products and services. Our future success will depend, in part, upon our ability to address the needs of our customers by using technology to provide products and services that will satisfy customer demands for convenience, as well as to create additional operational efficiencies and greater privacy and security protection for customers and their personal information. Many of our competitors have substantially greater resources to invest in technological improvements. We may not be able to effectively implement new technology-driven products and services or be successful in marketing these products and services to our customers. Failure to successfully keep pace with technological change affecting the financial services industry could impair our ability to retain or acquire new business and could have an adverse effect on our business, financial position, results of operations and liquidity.

We may not be able to protect our intellectual property, and we are subject to claims of third-party intellectual property rights.

If we are unable to protect our intellectual property and proprietary technology, our competitors may be able to duplicate our technology and products. To the extent that we do not effectively protect our proprietary intellectual property through patents or other means, other parties, including former employees, with knowledge of our intellectual property may seek to exploit our intellectual property for their own or others’ advantage. In addition, we may unintentionally infringe on claims of third-party patents, and we may face intellectual property challenges from other parties. We may not be successful in defending against any such challenges or in obtaining licenses to avoid or resolve any intellectual property disputes. Third-party intellectual rights, valid or not, may also impede our deployment of the full scope of our products and service capabilities in all of the market areas in which we operate or market our products and services. The intellectual property of an acquired business may be an important component of the value that we agree to pay for such a business. Such acquisitions, however, are subject to the risks that the acquired business may not own the intellectual property that we believe we are acquiring, that the intellectual property is dependent on licenses from third parties, that the acquired business infringes on the intellectual property rights of others, or that the technology does not have the acceptance in the marketplace that we may have anticipated.

We are subject to a variety of systems-failure and cyber security risks that could adversely affect our business and financial performance.

Our internal operations are subject to certain risks, including, but not limited to, information systems failures and errors, customer or employee fraud and catastrophic failures resulting from terrorist acts, data piracy or natural disasters.  We maintain a system of internal controls and security to mitigate the risks of many of these occurrences and maintain insurance coverage for certain risks.  However, should an event occur that is not prevented or detected by our internal controls, and is uninsured against or in excess of applicable insurance limits, such occurrence could have an adverse effect on our business, financial condition, results of operations and liquidity.

The computer systems and network infrastructure we use could be vulnerable to unforeseen problems. Our operations are dependent upon the ability to protect our computer equipment against damage from fire, severe storm, power loss, telecommunications failure or a similar catastrophic event. Any damage or failure of our computer systems or network infrastructure that causes an interruption in operations could have an adverse effect on our financial condition, results of operations and liquidity.

In addition, our operations are dependent upon our ability to protect the computer systems and network infrastructure against damage from physical break-ins, security breaches and other disruptive problems caused by Internet users or other users. Computer break-ins and other disruptions could jeopardize the security of information stored in and transmitted through our computer systems and networks, which may result in significant liability and reputation risk to us, and may deter potential customers. Although we, with the help of third-party service providers, intend to continue to actively monitor and, where necessary, implement improved security technology and develop additional operational procedures to prevent damage or unauthorized access to our computer systems and network, there can be no assurance that these security measures or operational procedures will be successful. In addition, new developments or advances in computer capabilities or new discoveries in the field of cryptography could enable hackers or data pirates to compromise or breach the security measures we use to protect customer data. Any failure to maintain adequate security over our customers’ personal and transactional information could expose us to reputational risk or consumer litigation, and could have an adverse effect on our financial condition, results of operations and liquidity.

28

Our risk and exposure to cyber attacks and other information security breaches remain heightened because of, among other things, the evolving nature of these threats and the prevalence of Internet and mobile banking. As cyber threats continue to evolve, we may be required to expend significant additional resources to continue to modify or enhance our protective measures or to investigate and remediate any information security vulnerabilities. Disruptions or failures in the physical infrastructure or operating systems that support our businesses and customers, or cyber attacks or security breaches of the networks, systems or devices that customers use to access our products and services, could result in customer attrition, regulatory fines, penalties or intervention, reputational damage, reimbursement or other compensation costs, including litigation expense and/or additional compliance costs, any of which could materially and adversely affect our business, results of operations or financial condition.

We rely on certain third-party vendors.

We are reliant upon certain third-party vendors to provide products and services necessary to maintain our day-to-day operations. Accordingly, our operations are exposed to risk that these vendors will not perform in accordance with applicable contractual arrangements or service level agreements. We maintain a system of policies and procedures designed to monitor vendor risks including, among other things, (i) changes in the vendor’s organizational structure, (ii) changes in the vendor’s financial condition, (iii) changes in existing products and services or the introduction of new products and services, and (iv) changes in the vendor’s support for existing products and services. While we believe these policies and procedures help to mitigate risk, the failure of an external vendor to perform in accordance with applicable contractual arrangements or the service level agreements could be disruptive to our operations, which could have a material adverse effect on our business and our financial condition and results of operations.

Reductions in interchange fees and the effects of the Durbin Amendment may reduce our non-interest income.

An interchange fee is a fee merchants pay to the interchange network in exchange for the use of the network’s infrastructure and payment facilitation, and which is paid to debit, credit and prepaid card issuers, including the Company, to compensate them for the costs associated with card issuance and operation. In the case of credit cards, this includes the risk associated with lending money to customers. Merchants, trying to decrease their operating expenses, have sought to, and have had some success at, lowering interchange rates. In particular, the Durbin Amendment to the Dodd-Frank Act limited the amount of interchange fees that may be charged for debit and prepaid card transactions and is applicable to financial institutions whose total assets exceed $10 billion.  We estimate that had we been subject to the Durbin Amendment during 2015, our interchange fee revenue would have been reduced by approximately $5.3 million. We also expect that our total assets will exceed $10 billion in 2016, which will subject us to the Durbin Amendment and, as a result, reduce our interchange fee income.

Recent events and actions indicate a continuing focus on interchange fees by both regulators and merchants. Beyond pursuing litigation, legislation and regulation, merchants are also pursuing alternate payment platforms as a means to lower payment processing costs. To the extent interchange fees are further reduced, our non-interest income from those fees will be reduced, which could have a material adverse effect on our business and results of operations. In addition, the payment card industry is subject to the operating regulations and procedures set forth by payment card networks, and our failure to comply with these operating regulations, which may change from time to time, could subject us to various penalties or fees or the termination of our license to use the payment card networks, all of which could have a material adverse effect on our business, financial condition or results of operations.

Natural disasters may adversely affect us.

Our operations and customer base are located in markets where natural disasters, including tornadoes, severe storms, fires, floods, hurricanes and earthquakes often occur. Such natural disasters could significantly impact the local population and economies and our business, and could pose physical risks to our properties. Although our banking offices are geographically dispersed primarily throughout the south central and southeastern portions of the United States and we maintain insurance coverages for such events, a significant natural disaster in or near one or more of our markets could have a material adverse effect on our financial condition, results of operations or liquidity.

RISKS ASSOCIATED WITH OUR INDUSTRY

We are subject to extensive government regulation that limits or restricts our activities and could adversely affect our operations.

We operate in a highly regulated industry and are subject to examination, supervision and comprehensive regulation by various federal and state agencies. Compliance with these regulations is costly and restricts certain activities, including payment of dividends on shares of our common stock, mergers and acquisitions, investments, interest rates charged for loans and leases, interest rates paid on deposits, locations of banking offices and various other activities and aspects of our operations. We are also subject to capital guidelines established by regulators which require maintenance of adequate capital. Many of these regulations are intended to protect

29

depositors, the public and the FDIC’s DIF rather than shareholders. Additionally, in order to conduct certain activities, including acquisitions, we are required to obtain regulatory approval. There can be no assurance that any required approvals can be obtained, or obtained without conditions or on a timeframe acceptable to us.

The Sarbanes-Oxley Act of 2002 and the related rules and regulations issued by the SEC and NASDAQ, as well as numerous other recently enacted statutes and regulations, including the Dodd-Frank Act and regulations promulgated thereunder, have increased the scope, complexity and cost of corporate governance and reporting and disclosure practices, including the costs of completing our external audit and maintaining our internal controls.

Government regulation greatly affects the business and financial results of all commercial banks and bank holding companies, and increases our costs of complying with regulatory requirements. Additionally, the failure to comply with these various rules and regulations could subject us to monetary penalties or sanctions or otherwise expose us to reputational risk and could adversely affect our results of operations.

Newly enacted and proposed legislation and regulations may affect our operations and growth.

To address the recent turbulence in the U.S. economy and the banking and financial markets, the U.S. government has enacted a series of laws, regulations, guidelines and programs, many of which are discussed under the section “Item 1─Business─Supervision and Regulation” in this Annual Report on Form 10-K. The changes resulting from the Dodd-Frank Act may affect the profitability of our business activities, require changes to certain of our business practices, impose upon us more stringent capital, liquidity and leverage requirements or otherwise adversely affect our business. In particular, the potential effect of the Dodd-Frank Act on our operations and activities, both currently and prospectively, may include, among others:

· a reduction in our ability to generate or originate revenue-producing assets as a result of compliance with heightened capital standards;

· an increased cost of operations due to greater regulatory oversight, supervision and examination of banks and bank holding companies, and higher deposit insurance premiums;

· the limitation on our ability to raise qualifying regulatory capital through the use of trust preferred securities as these securities may no longer be included in Tier 1 capital going forward; and

· the limitations on our ability to offer certain consumer products and services due to anticipated stricter consumer protection laws and regulations.

Examples of these provisions include, but are not limited to:

· creation of the Financial Stability Oversight Council 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;

· 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 with provisions to require institutions with total consolidated assets of $10 billion or more to bear a greater portion of the costs associated with increasing the DIF’s reserve ratio;

· establishment of the CFPB with broad authority to implement new consumer protection regulations and, for bank holding companies with $10 billion or more in assets, to examine and enforce compliance with federal consumer 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, give the FRB the authority to issue rules limiting debit card interchange fees.

Further, we may be required to invest significant management attention and resources to evaluate and make any changes necessary to comply with new statutory and regulatory requirements under the Dodd-Frank Act as we continue to grow and exceed $10 billion in total assets. The Dodd-Frank Act created a new independent CFPB within the FRB. The CFPB is tasked with establishing and implementing rules and regulations under certain federal consumer protection laws with respect to the conduct of providers of certain consumer financial products and services. The CFPB has rulemaking authority over many of the statutes governing products and services offered to bank consumers. For banking organizations with assets of $10 billion or more, the CFPB has exclusive rulemaking and examination authority, and primary enforcement authority for most federal consumer financial laws. In addition, the Dodd-Frank Act permits states to adopt consumer protection laws and regulations that are stricter than those regulations

30

promulgated by the CFPB. Compliance with any such new regulations will increase our cost of operations. Failure to comply with these new requirements, among others, may negatively affect our results of operations and financial condition.

Additionally, in the routine course of regulatory oversight, proposals to change the laws and regulations governing the operations and taxation of, and federal insurance premiums paid by, banks and other financial institutions and companies that control financial institutions are frequently raised in the U.S. Congress, state legislatures and before bank regulatory authorities. The likelihood of significant changes in laws and regulations in the future and the effect that such changes might have on our operations are impossible to determine. Similarly, proposals to change the accounting, financial reporting requirements applicable to banks and other depository institutions are frequently raised by the SEC, the federal banking agencies and other authorities. Further, federal intervention in financial markets and the commensurate effect on financial institutions may adversely affect our rights under contracts with such other institutions and the way in which we conduct business in certain markets. The likelihood and impact of any future changes in these accounting and financial reporting requirements and the effect these changes might have on our business and operations are also impossible to determine at this time.

We will be subject to heightened regulatory requirements when we exceed $10 billion in assets.

Based on our historic organic growth rates, we expect that our total assets will exceed $10 billion during 2016. The Dodd-Frank Act and its implementing regulations impose various additional requirements on bank holding companies with $10 billion or more in total assets, including compliance with portions of the FRB’s enhanced prudential oversight requirements and annual stress testing requirements. In addition, banks with $10 billion or more in total assets are primarily examined by the CFPB with respect to various federal consumer financial protection laws and regulations. Currently, our bank subsidiary is subject to regulations adopted by the CFPB, but the FDIC is primarily responsible for examining our compliance with consumer protection laws and those CFPB regulations. As a relatively new agency with evolving regulations and practices, there is uncertainty as to how the CFPB’s examination and regulatory authority might affect our business.

Compliance with these requirements will necessitate that we hire additional compliance or other personnel, design and implement additional internal controls, or incur other significant expenses, all of which could have a material adverse effect on our business, financial condition or results of operations. Compliance with the annual stress testing requirements, part of which must be publicly disclosed, may also be misinterpreted by the market generally or our customers and, as a result, may adversely affect our stock price or our ability to retain our customers or effectively compete for new business opportunities.

Consumers may decide not to use community banks to complete their financial transactions.

Technology and other changes are allowing parties to complete, through alternative methods, financial transactions that historically have involved community banks. For example, consumers can now maintain funds that would have historically been held as local bank deposits in brokerage accounts, mutual funds with an Internet-only bank, or with virtually any bank in the country through online banking. Consumers can also complete transactions such as purchasing goods and services, paying bills and/or transferring funds directly without the assistance of banks. The process of eliminating banks as intermediaries could result in the loss of fee income, as well as the loss of customer deposits and the related income generated from those deposits. The loss of these revenue streams and the lower-cost deposits as a source of funds could have an adverse effect on our financial condition, results of operations and liquidity.

RISKS ASSOCIATED WITH OUR COMMON STOCK

The price of our common stock is affected by a variety of factors, many of which are outside our control.

Stock price volatility may make it more difficult for investors to sell shares of our common stock at times and prices they find attractive. Our common stock price can fluctuate significantly in response to a variety of factors, including, among other things:

· actual or anticipated variations in quarterly results of operations;

· recommendations or changes in recommendations by securities analysts;

· operating and stock price performance of other companies that investors deem comparable to us;

· news reports relating to trends, concerns and other issues in the financial services industry;

· perceptions in the marketplace about us and/or our competitors;

· new technology used, or services offered, by competitors;

31

· significant acquisitions or business combinations, strategic partnerships, joint ventures, or capital commitments by or involving us or our competitors; and  

· changes in governmental regulations.

General market fluctuations, industry factors and general economic and political conditions and events such as economic slowdowns, expected or incurred interest rate changes, credit loss trends and various other factors and events could adversely affect the price of our common stock.

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

Our shareholders are only entitled to receive such dividends as our board of directors may declare out of funds legally available for such payments. Although we have historically declared cash dividends on our common stock, we are not required to do so and may reduce or eliminate our common stock dividend in the future. Our ability to pay dividends to our shareholders is subject to the restrictions set forth in Arkansas law, by our federal regulator, and by certain covenants contained in the indentures governing our trust preferred securities.

Our principal business operations are conducted through our bank subsidiary.  Cash available to pay dividends to our common shareholders is derived primarily, if not entirely, from dividends paid by our bank subsidiary. The ability of our bank subsidiary to pay dividends, as well as our ability to pay dividends to our common shareholders, will continue to be subject to and limited by the results of operations of our bank subsidiary and by certain legal and regulatory restrictions.  Further, any lenders making loans to us may impose financial covenants that may be more restrictive than regulatory requirements with respect to our payment of dividends to common shareholders. Accordingly, there can be no assurance that we will continue to pay dividends to our common shareholders in the future.  See Note 19 to the Consolidated Financial Statements included elsewhere in this Annual Report on Form 10-K for a discussion of dividend restrictions.

Certain state and/or federal laws may deter potential acquirers and may depress our stock price.

Certain provisions of federal and state laws may have the effect of making it more difficult for a third party to acquire, or of discouraging a third party from attempting to acquire, control of us. Under certain federal and state laws, a person, entity, or group must give notice to applicable regulatory authorities before acquiring a significant amount, as defined by such laws, of the outstanding voting stock of a bank holding company, including shares of our common stock. Regulatory authorities review the potential acquisition to determine if it will result in a change of control. The applicable regulatory authorities will then act on the notice, taking into account the resources of the potential acquirer, the potential antitrust effects of the proposed acquisition and numerous other factors. As a result, these statutory provisions may delay, defer or prevent a tender offer or takeover attempt that a shareholder might consider to be in such shareholder’s best interest, including those attempts that might result in a premium over the market price for the shares held by shareholders.

The holders of our subordinated debentures have rights that are senior to those of our common shareholders and any future debt or preferred equity securities we may offer may adversely affect the market price of our common stock.

At December 31, 2015, we had an aggregate of $118 million of floating rate subordinated debentures and related trust preferred securities outstanding. We guarantee payment of the principal and interest on the trust preferred securities, and the subordinated debentures are senior to shares of our common stock. As a result, we must make payments on the subordinated debentures (and the related trust preferred securities) before any dividends can be paid on shares of our common stock and, in the event of our bankruptcy, dissolution or liquidation, the holders of the subordinated debentures would receive a distribution from our available assets before any distributions could be made to the holders of common stock. We have the right to defer distributions on our subordinated debentures and the related trust preferred securities for up to five years, during which time no dividends may be paid to holders of our common stock.

We may from time to time issue debt securities, which would be senior to our common stock upon liquidation, and/or preferred equity securities, which may be senior to our common stock for purposes of dividend distributions or upon liquidation, borrow money through other means, or issue preferred stock. Our board of directors is authorized to issue one or more classes or series of preferred stock from time to time without any action on the part of our shareholders. Our board of directors also has the power, without shareholder approval, to set the terms of any such classes or series of preferred stock that may be issued, including voting rights, dividend rights, and preferences over our common stock with respect to dividends or upon our dissolution, winding-up and liquidation and other terms. If we issue preferred stock in the future that has a preference over our common stock with respect to the payment of dividends or upon our liquidation, dissolution, or winding up, or if we issue preferred stock with voting rights that dilute the voting

32

power of our common stock, the rights of holders of our common stock or the market price of our common stock could be adversely affected.

Our common stock trading volume may not provide adequate liquidity for investors.

Although shares of our common stock are listed on the NASDAQ Global Select Market, the average daily trading volume in the common stock is less than that of many larger financial services companies. A public trading market having the desired characteristics of depth, liquidity and orderliness depends on the presence in the marketplace of a sufficient number of willing buyers and sellers of the common stock at any given time. This presence depends on the individual decisions of investors and general economic and market conditions over which we have no control. Given the daily average trading volume of our common stock, significant sales of our common stock in a brief period of time, or the expectation of these sales, could cause a decline in the price of our common stock.

Future issuances of additional equity securities could result in dilution of existing stockholders’ equity ownership.

We may determine from time to time to issue additional equity securities to raise additional capital, support growth, or, as we have in recent years, to make acquisitions.  Further, we may issue stock options, grant restricted stock awards or other stock grants to retain, compensate and/or motivate our employees and directors.  These issuances of our securities could dilute the voting and economic interests of existing shareholders.

Our common stock is not an insured deposit.

Shares of our common stock are not a bank deposit and, therefore, losses in value are not insured by the FDIC, any other deposit insurance fund or by any other public or private entity. Investment in shares of our common stock is inherently risky for the reasons described in this “Risk Factors” section and elsewhere in this Annual Report on Form 10-K, and is subject to the same market forces and investment risks that affect the price of common stock in any other company, including the possible loss of some or all principal invested.

Item 3. LEGAL PROCEEDINGS 

On January 5, 2012, the Company and the Bank were served with a summons and complaint filed on December 19, 2011, in the Circuit Court of Lonoke County, Arkansas, Division III, styled Robert Walker, Ann B. Hines and Judith Belk vs. Bank of the Ozarks, Inc. and Bank of the Ozarks, Case No. CV-2011-777. In addition, on December 21, 2012, the Bank was served with a summons and complaint filed on December 20, 2012, in the Circuit Court of Pulaski County, Arkansas, Ninth Division, styled Audrey Muzingo v. Bank of the Ozarks, Case No. 60 CV-12-6043. The complaint in each case alleges that the Company and/or Bank have harmed the plaintiffs, current or former customers of the Bank, by improper, unfair, and unconscionable assessment and collection of excessive overdraft fees from the plaintiffs. According to the complaints, plaintiffs claim that the Bank employs sophisticated software to automate its overdraft system, and that this system unfairly and inequitably manipulates and alters customers’ transaction records in order to maximize overdraft penalties, particularly utilizing a practice of posting of items in “high-to-low” order, despite the actual sequence in which such items are presented for payment. Plaintiffs claim that the Bank’s deposit agreements with customers do not adequately disclose the Bank’s overdraft assessment policies and are ambiguous, deceptive, unfair, and misleading. The complaint in each case alleges that these actions and omissions constitute breach of contract, breach of the implied covenant of good faith and fair dealing, unconscionable conduct, conversion, unjust enrichment, and violation of the Arkansas Deceptive Trade Practices Act.  Each of the complaints seeks to have the cases certified by the court as a class action for all Bank account holders similarly situated, and seeks a declaratory judgment as to the wrongful nature of the Bank’s overdraft fee policies, restitution of overdraft fees paid by the plaintiffs and the putative class (defined as all Bank customers residing in Arkansas) as a result of the actions cited in the complaints, disgorgement of profits as a result of the alleged wrongful actions, and unspecified compensatory and statutory or punitive damages, together with pre-judgment interest, costs, and plaintiffs’ attorneys’ fees.

The Company and Bank filed a motion to dismiss and to compel arbitration in the Walker case. The trial court denied the motion and found that the arbitration provision contained in the controlling Consumer Deposit Account Agreement was unconscionable and thus unenforceable on the grounds that the provision was the result of unequal bargaining power. On September 18, 2013, the Arkansas Court of Appeals reversed the trial court’s ruling and remanded the case to the trial court for the purpose of entering an order compelling arbitration. On October 7, 2013, the plaintiffs filed petitions for reconsideration and review before the Arkansas Court of Appeals and Arkansas Supreme Court, respectively. On May 15, 2014, the Arkansas Supreme Court vacated the Arkansas Court of Appeals’ decision, reversing and remanding the case to the trial court to determine, in the first instance, whether there is a valid agreement to arbitrate disputes between the named plaintiffs and the Bank.

On October 30, 2014, the trial court issued an order once again denying the Company and Bank’s motion to dismiss and to compel arbitration, finding that the Consumer Deposit Account Agreement containing the arbitration provision was not enforceable because of a lack of mutual agreement and lack of mutual obligation. The Company and Bank have appealed the trial court’s ruling to the Arkansas Supreme Court on an interlocutory basis. A ruling from the Arkansas Supreme Court is expected in the first quarter of 2016.

The Plaintiff in the Muzingo case has agreed to stay the proceedings in that case pending the outcome of the appeal in the Walker case. The Company and the Bank believe the Plaintiffs’ claims in each of these cases are unfounded and subject to meritorious defenses and intend to vigorously defend against these claims.

The Company is party to various other legal proceedings, as both plaintiff and defendant, arising in the ordinary course of business, including claims of lender liability, broken promises, and other similar lending-related claims. While the ultimate resolution of these various claims and proceedings cannot be determined at this time, management of the Company believes that such claims and proceedings, individually or in the aggregate, will not have a material adverse effect on the future results of operations, financial condition, or liquidity of the Company.

PART II

Item 5. MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED SHAREHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

The Company’s common stock is listed on the NASDAQ Global Select Market under the symbol “OZRK” and as of December 31, 2015, the Company had approximately 1,100 holders of record. At December 31, 2015 the closing price of our common stock was $49.46 per share.  The following table sets forth for each quarter of 2015 and 2014, the high and low sales price of our common stock and the cash dividends declared per share.

	Year Ended December 31,

						0.550					$	0.470

Our principal business operations are conducted through our bank subsidiary. Cash available to pay dividends to our common shareholders is derived primarily, if not entirely, from dividends paid by our bank subsidiary. The ability of our bank subsidiary to pay dividends, as well as our ability to pay dividends to our common shareholders, will continue to be subject to and limited by the results of operations of our bank subsidiary and by certain legal and regulatory restrictions. 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 to common shareholders. Accordingly, there can be no assurance that we will continue to pay dividends to our common shareholders in the future. See Note 19 to the Consolidated Financial Statements included elsewhere in this Annual Report on Form 10-K for further discussion of dividend restrictions.

The graph below shows a comparison for the period commencing December 31, 2010 through December 31, 2015 of the cumulative total stockholder returns (assuming reinvestment of dividends) for our common stock, the S&P Midcap 400 Index and the NASDAQ Financial Index, assuming a $100 investment on December 31, 2010.

Item 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS 

Overview

The following is a discussion of our financial condition at December 31, 2015 and 2014 and our results of operations for each of the years in the three-year period ended December 31, 2015. The purpose of this management’s discussion and analysis of financial condition and results of operations (“MD&A”) is to focus on information about our financial condition and results of operations that is not otherwise apparent from the Consolidated Financial Statements and footnotes. This discussion should be read in conjunction with the disclosure regarding “Forward-Looking Statements” in Part I as well as the risks discussed under “Item 1A. Risk Factors,” and our Consolidated Financial Statements and notes thereto included under “Item 8. Financial Statements and Supplementary Data.”

Bank of the Ozarks, Inc. (“Company”) is a bank holding company whose primary business is commercial banking conducted through our wholly-owned state chartered bank subsidiary – Bank of the Ozarks (the “Bank”). Our results of operations depend primarily on net interest income, which is the difference between the interest income from earning assets, such as loans and leases and investments, and the interest expense incurred on interest bearing liabilities, such as deposits, borrowings and subordinated debentures. We also generate non-interest income, including service charges on deposit accounts, mortgage lending income, trust income, bank owned life insurance (“BOLI”) income, other income from purchased loans, gains and losses on investment securities and from sales of other assets, and gains on merger and acquisition transactions.

Our non-interest expense consists primarily of employee compensation and benefits, net occupancy and equipment expense and other operating expenses. Our results of operations are significantly affected by our provision for loan and lease losses and our provision for income taxes.

Critical Accounting Policies

The preparation of financial statements in conformity with accounting principles generally accepted in the United States, or GAAP, requires management to make estimates, assumptions and judgments that affect the amounts reported in the Consolidated Financial Statements. Our determination of (i) the provisions to and the adequacy of the allowance for loan and lease losses (“ALLL”), (ii) the fair value of our investment securities portfolio, (iii) the fair value of foreclosed assets and (iv) the fair value of the assets acquired and liabilities assumed pursuant to business combination transactions all involve a higher degree of judgment and complexity than our other significant accounting policies. Accordingly, we consider the determination of (i) provisions to and the adequacy of the ALLL, (ii) the fair value of our investment securities portfolio, (iii) the fair value of foreclosed assets and (iv) the fair value of the assets acquired and liabilities assumed pursuant to business combination transactions to be critical accounting policies.

Provisions to and adequacy of the ALLL. The ALLL is established through a provision for such losses charged against income. All or portions of loans or leases deemed to be uncollectible are charged against the ALLL when management believes that collectability of all or some portion of outstanding principal is unlikely. Subsequent recoveries, if any, of loans or leases previously charged off are credited to the ALLL.

The ALLL is maintained at a level we believe will be adequate to absorb probable incurred losses in the loan and lease portfolio. Provisions to and the adequacy of the ALLL are based on evaluations of the loan and lease portfolio utilizing objective and subjective criteria. The objective criteria primarily include an internal grading system and specific allowances. In addition to these objective criteria, we subjectively assess the adequacy of the ALLL and the need for additions thereto, with consideration given to the nature and mix of the portfolio, including concentrations of credit; general economic and business conditions, including national, regional and local business and economic conditions that may affect borrowers’ or lessees’ ability to pay; expectations regarding the current business cycle; trends that could affect collateral values and other relevant factors. We also utilize a peer group analysis and a historical analysis to validate the overall adequacy of our ALLL. Changes in any of these criteria or the availability of new information could require adjustment of the ALLL in future periods. While a specific allowance has been calculated for impaired loans and leases and for loans and leases where we have otherwise determined a specific reserve is appropriate, no portion of our ALLL is restricted to any individual loan or lease or group of loans or leases, and the entire ALLL is available to absorb losses from any and all loans and leases.

Our internal grading system assigns grades to all non-purchased loans and leases, except residential 1-4 family loans, consumer loans and certain other loans, with each grade being assigned an allowance allocation percentage. The grade for each graded individual loan or lease is determined by the account officer and other approving officers at the time the loan or lease is made and changed from time to time to reflect an ongoing assessment of loan or lease risk. Grades are reviewed on specific loans and leases from time to time by senior management and as part of our internal loan review process. These risk elements considered in our determination of the appropriate grade for individual loans and leases include the following, among others: (1) for non-farm/non-

39

residential, multifamily residential, and agricultural real estate loans, the debt service coverage ratio (income from the property in excess of operating expenses compared to loan repayment requirements), operating results of the owner in the case of owner-occupied properties, the loan-to-value ratio, the age, condition, value, nature and marketability of the collateral and the specific risks and volatility of income, property value and operating results typical of properties of that type; (2) for construction and land development loans, the perceived feasibility of the project including the ability to sell developed lots or improvements constructed for resale or ability to lease property constructed for lease, the quality and nature of contracts for presale or preleasing, if any, experience and ability of the developer and loan-to-cost and loan-to-value ratios; (3) for commercial and industrial loans and leases, the operating results of the commercial, industrial or professional enterprise, the borrower’s or lessee’s business, professional and financial ability and expertise, the specific risks and volatility of income and operating results typical for businesses in the applicable industry, the age, condition, value, nature and marketability of collateral and, for certain loans, the marketability of such loans in any secondary market; and (4) for non-real estate agricultural loans and leases, the operating results, experience and ability of the borrower or lessee, historical and expected market conditions and the age, condition, value, nature and marketability of collateral. In addition, for each category we consider secondary sources of income and the financial strength of the borrower or lessee and any guarantors.

Residential 1-4 family, consumer loans and certain other loans are assigned an allowance allocation percentage based on past due status.

Allowance allocation percentages for the various risk grades and past due categories for residential 1-4 family, consumer loans and certain other loans are determined by management and are adjusted periodically. In determining these allowance allocation percentages, we consider, among other factors, historical loss percentages over various time periods and a variety of subjective criteria.

Assets acquired and liabilities assumed in business combinations are recorded at estimated fair value on their purchase date. As provided for under GAAP, we have up to 12 months following the date of the acquisition to finalize the fair values of acquired assets and assumed liabilities. Once we have finalized the fair values of acquired assets and assumed liabilities within this 12-month period, we consider such values to be the day 1 fair values (“Day 1 Fair Values”).

For purchased loans, we segregate this portfolio into loans that contain evidence of credit deterioration on the date of acquisition and loans that do not contain evidence of credit deterioration on the date of acquisition. Purchased loans with evidence of credit deterioration are regularly monitored and are periodically reviewed by management. To the extent that a loan’s performance has deteriorated from our expectations established in conjunction with the determination of the Day 1 Fair Values, such loan is considered in the determination of the required level of ALLL. To the extent that a revised loss estimate exceeds the loss estimate established in the determination of Day 1 Fair Values, such determination will result in an allowance allocation or a charge-off.

All other purchased loans are graded by management at the time of purchase. The grade on these purchased loans is reviewed regularly as part of the ongoing assessment of such loans. To the extent that current information indicates it is probable that we will not be able to collect all amounts according to the contractual terms thereof, such loan is considered in the determination of the required level of ALLL and may result in an allowance allocation or a charge-off.

At December 31, 2015, we had established an ALLL totaling $1.2 million for our purchased loan portfolio.  Such ALLL was based on our historical charge-off analysis of the purchased loan portfolio and reflects our estimate of probable incurred losses in the purchased loan portfolio that had not previously been charged off.  At December 31, 2014, we had no ALLL for our purchased loan portfolio as we had determined that all losses had been charged off on purchased loans where we had determined it was probable that we would be unable to collect all amounts according to the contractual terms thereof (for purchased loans without evidence of credit deterioration at date of acquisition) or whose performance had deteriorated from management’s expectations established in conjunction with the determination of Day 1 Fair Values (for purchased loans with evidence of credit deterioration at date of acquisition).

The accrual of interest on non-purchased loans and leases and purchased loans without evidence of credit deterioration at the date of acquisition is discontinued when, in our opinion, the borrower or lessee may be unable to meet payments as they become due. We generally place a loan or lease, excluding purchased loans with evidence of credit deterioration on the date of acquisition, on nonaccrual status when such loan or lease is (i) deemed impaired or (ii) 90 days or more past due, or earlier when doubt exists as to the ultimate collection of payments. We may continue to accrue interest on certain loans or leases contractually past due 90 days or more if such loans or leases are both well secured and in the process of collection. At the time a loan or lease is placed on nonaccrual status, interest previously accrued but uncollected is reversed and charged against interest income. Nonaccrual loans and leases are generally returned to accrual status when payments are less than 90 days past due and we reasonably expect to collect all payments. If a loan or lease is determined to be uncollectible, the portion of the principal determined to be uncollectible will be charged against the ALLL. Loans for which the terms have been modified and for which (i) the borrower is experiencing financial difficulties and (ii) we have granted a concession to the borrower are considered troubled debt restructurings (“TDRs”) and are included in impaired loans

40

and leases. Income on nonaccrual loans or leases, including impaired loans and leases but excluding certain TDRs which continue to accrue interest, is recognized on a cash basis when and if actually collected.

All loans and leases deemed to be impaired are evaluated individually. We consider a loan or lease, excluding purchased loans with evidence of credit deterioration at the date of acquisition, to be impaired when based on current information and events, it is probable that we will be unable to collect all amounts due according to the contractual terms thereof. We consider a purchased loan with evidence of credit deterioration at the date of acquisition to be impaired once a decrease in expected cash flows or other deterioration in the loan’s expected performance, subsequent to the determination of the Day 1 Fair Values, results in an allowance allocation, a partial or full charge-off or in a provision for loan and lease losses. Most of our nonaccrual loans and leases, excluding purchased loans with evidence of credit deterioration at the date of acquisition, and all TDRs are considered impaired. The majority of our impaired loans and leases are dependent upon collateral for repayment. For such loans and leases, impairment is measured by comparing collateral value, net of holding and selling costs, to the current investment in the loan or lease. For all other impaired loans and leases, we compare estimated discounted cash flows to the current investment in the loan or lease. To the extent that our current investment in a particular loan or lease exceeds the estimated net collateral value or the estimated discounted cash flows, the impaired amount is specifically considered in the determination of the ALLL or is charged off as a reduction of the ALLL. Our practice is to charge off any estimated loss as soon as management is able to identify and reasonably quantify such potential loss. Accordingly, only a small portion of our ALLL is needed for potential losses on nonperforming loans.

We also maintain an allowance for certain non-purchased loans and leases not considered impaired where (i) the customer is continuing to make regular payments, although payments may be past due, (ii) there is a reasonable basis to believe the customer may continue to make regular payments, although there is also an elevated risk that the customer may default, and (iii) the collateral or other repayment sources are likely to be insufficient to recover the current investment in the loan or lease if a default occurs. We evaluate such loans and leases to determine if an allowance is needed for these loans and leases. For the purpose of calculating the amount of such allowance, we assume that (i) no further regular payments occur and (ii) all sums recovered will come from liquidation of collateral and collection efforts from other payment sources. To the extent that our current investment in a particular loan or lease evaluated for the need for such allowance exceeds its net collateral value, such excess is considered allocated allowance for purposes of the determination of the ALLL.

We also include specific ALLL allocations for qualitative factors including, (i) general economic and business conditions, (ii) trends that could affect collateral values and (iii) expectations regarding the current business cycle. We may also consider other qualitative factors in future periods for additional ALLL allocations.

Changes in the criteria used in this evaluation or the availability of new information could cause our ALLL to be increased or decreased in future periods. In addition, bank regulatory agencies, as part of their examination process, may require adjustments to our ALLL based on their judgment and estimates.

Fair value of the investment securities portfolio. We determine the appropriate classification of investment securities at the time of purchase and reevaluate such designation as of each balance sheet date. At December 31, 2015 and 2014, we classified all of our investment securities as available for sale (“AFS”).

Investment securities AFS are stated at estimated fair value, with the unrealized gains and losses determined on a specific identification basis. Such unrealized gains and losses, net of tax, are reported as a separate component of stockholders’ equity and included in other comprehensive income (loss). We utilize independent third parties as our principal pricing sources for determining fair value of investment securities which are measured on a recurring basis. As a result, we receive estimates of fair values from at least two independent pricing sources for the majority of our individual securities within our investment portfolio. For investment securities traded in an active market, fair values are based on quoted market prices if available. If quoted market prices are not available, fair values are based on quoted market prices of comparable securities, broker quotes or comprehensive interest rate tables, pricing matrices or a combination thereof. For investment securities traded in a market that is not active, fair value is determined using unobservable inputs. Additionally, the valuation of investment securities acquired may include certain unobservable inputs. All fair value estimates we receive for our investment securities are reviewed and approved on a quarterly basis by our Investment Portfolio Manager and our Chief Financial Officer.

Declines in the fair value of investment securities below their amortized cost are reviewed at least quarterly for other-than-temporary impairment. Factors considered during such review include, among other things, the length of time and extent that fair value has been less than cost and the financial condition and near term prospects of the issuer. We also assess whether we have the intent to sell the investment security or more likely than not would be required to sell the investment security before any anticipated recovery in fair value. If either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost and fair value is recognized as impairment through the income statement. For securities that do not meet the aforementioned criteria, the amount of impairment is split into (i) other-than-temporary impairment related to credit loss, which must be recognized in

41

the income statement, and (ii) other-than-temporary impairment related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis.

The fair values of our investment securities traded in both active and inactive markets can be volatile and may be influenced by a number of factors including market interest rates, prepayment speeds, discount rates, credit quality of the issuer, general market conditions including market liquidity conditions and other factors. Factors and conditions are constantly changing and fair values could be subject to material variations that may significantly impact our financial condition, results of operations and liquidity.

Fair value of foreclosed assets. Repossessed personal properties and real estate acquired through or in lieu of foreclosure, excluding purchased foreclosed assets, are initially recorded at the lesser of current principal investment or fair value less estimated cost to sell (generally 8% to 10%) at the date of repossession or foreclosure. Purchased foreclosed assets are initially recorded at Day 1 Fair Values. In estimating such Day 1 Fair Values, we consider a number of factors including, among others, appraised value, estimated selling price, estimated holding periods and net present value (calculated using discount rates ranging from 8.0% to 9.5% per annum) of cash flows expected to be received.

Valuations of all foreclosed assets are periodically reviewed by management with the carrying value of such assets adjusted through non-interest expense to the then estimated fair value, generally based on third party appraisals, broker price opinions or other valuations of the property, net of estimated selling costs, if lower, until disposition.

Fair value of assets acquired and liabilities assumed pursuant to business combination transactions. Purchased loans are initially recorded at fair value on the date of acquisition. Purchased loans that contain evidence of credit deterioration on the date of  acquisition are carried at the net present value of expected future proceeds. All other purchased loans are recorded at their initial fair value, adjusted for subsequent advances, pay downs, amortization or accretion of any premium or discount on purchase, charge-offs and any other adjustment to carrying value.

At the time of acquisition of purchased loans, we individually evaluate substantially all loans acquired in the transaction. For those purchased loans without evidence of credit deterioration, we evaluate each reviewed loan using an internal grading system with a grade assigned to each loan at the date of acquisition. To the extent that any purchased loan is not specifically reviewed, such loan is assumed to have characteristics similar to the characteristics of the aggregate acquired portfolio of purchased loans. The grade for each purchased loan without evidence of credit deterioration is reviewed subsequent to the date of acquisition any time a loan is renewed or extended or at any time information becomes available to us that provides material insight regarding the loan’s performance, the borrower or the underlying collateral. To the extent that current information indicates it is probable that we will collect all amounts according to the contractual terms thereof, such loan is not considered impaired and is not individually considered in the determination of the required ALLL. To the extent that current information indicates it is probable that we will not be able to collect all amounts according to the contractual terms thereon, such loan is considered impaired and is considered in the determination of the required level of ALLL.

In determining the Day 1 Fair Values of purchased loans without evidence of credit deterioration at the date of acquisition, we include (i) no carryover of any previously recorded ALLL and (ii) an adjustment of the unpaid principal balance to reflect an appropriate market rate of interest, given the risk profile and grade assigned to each loan. This adjustment is accreted into earnings as a yield adjustment, using the effective yield method, over the remaining life of each loan.

Purchased loans that contain evidence of credit deterioration on the date of acquisition are individually evaluated to determine the estimated fair value of each loan. This evaluation includes no carryover of any previously recorded ALLL. In determining the estimated fair value of purchased loans with evidence of credit deterioration, we consider a number of factors including, among other things, the remaining life of the acquired loans, estimated prepayments, estimated loss ratios, estimated value of the underlying collateral, estimated holding periods, and net present value of cash flows expected to be received.

In determining the Day 1 Fair Values of purchased loans with evidence of credit deterioration, we calculate a non-accretable difference (the credit component of the purchased loans) and an accretable difference (the yield component of the purchased loans). The non-accretable difference is the difference between the contractually required payments and the cash flows expected to be collected in accordance with our determination of the Day 1 Fair Values. Subsequent increases in expected cash flows will result in an adjustment to accretable yield, which will have a positive impact on interest income. Subsequent decreases in expected cash flows will generally result in a provision for loan and lease losses. Subsequent increases in expected cash flows following any previous decrease will result in a reversal of the provision for loan and lease losses to the extent of prior charges and then an adjustment to accretable yield.

42

The accretable difference on purchased loans with evidence of credit deterioration is the difference between the expected cash flows and the net present value of expected cash flows. Such difference is accreted into earnings using the effective yield method over the term of the loans. In determining the net present value of the expected cash flows for purposes of establishing the Day 1 Fair Values, we used discount rates ranging from 6.0% to 9.5% per annum depending on the risk characteristics of each individual loan.

We separately monitor purchased loans with evidence of credit deterioration on the date of acquisition and periodically review such loans contained within this portfolio against the factors and assumptions used in determining the Day 1 Fair Values. A loan is reviewed (i) any time it is renewed or extended, (ii) at any other time additional information becomes available to us that provides material additional insight regarding the loan’s performance, the status of the borrower, or the quality or value of the underlying collateral, or (iii) in conjunction with the annual review of projected cash flows of each acquired portfolio. We separately review the performance of the portfolio of purchased loans with evidence of credit deterioration on an annual basis, or more frequently to the extent that material information becomes available regarding the performance of an individual loan, to make determinations of the constituent loans’ performance and to consider whether there has been any significant change in performance since our initial expectations established in conjunction with the determination of the Day 1 Fair Values or since our most recent review of such portfolio’s performance. To the extent that a loan is performing in accordance with or exceeding our performance expectation established in conjunction with the determination of the Day 1 Fair Values, such loan is rated FV66, is not included in any of the credit quality ratios, is not considered to be a nonaccrual, nonperforming or impaired loan, and is not considered in the determination of the required ALLL. For any loan that is exceeding our performance expectation established in conjunction with the determination of Day 1 Fair Values, the accretable yield on such loan is adjusted to reflect such increased performance. To the extent that a loan’s performance has deteriorated from our expectation established in conjunction with the determination of the Day 1 Fair Values, such loan is rated FV88, is included in certain of our credit quality metrics, is considered an impaired loan, and is considered in the determination of the required level of ALLL; however, in accordance with GAAP, we continue to accrete into earnings income on such loans. Any improvement in the expected performance of such loan would result in a reversal of the provision for loan and lease losses to the extent of prior charges and then an adjustment to accretable yield.

The Day 1 Fair Values of investment securities acquired in business combinations are generally based on quoted market prices, broker quotes, comprehensive interest rate tables or pricing matrices, or a combination thereof. Additionally, these valuations may include certain unobservable inputs. The Day 1 Fair Values of assumed liabilities in business combinations are generally the amounts payable by us necessary to completely satisfy the assumed obligations.

As a result of recording, at fair value, acquired assets and assumed liabilities pursuant to business combinations, differences in amounts reported for financial statement purposes and their related basis for federal and state income tax purposes are created. Such differences are recorded as deferred tax assets and liabilities using enacted tax rates in effect for the year or years in which the differences are expected to be recovered or settled. Business combination transactions may result in the acquisition of net operating loss carryforwards and other assets with built-in losses, the realization of which are subject to limitations pursuant to section 382 (“section 382 limitation”) of the Internal Revenue Code (“IRC”). In determining the section 382 limitation associated with a business combination, we must make a number of estimates and assumptions regarding the ability to utilize acquired net operating loss carryforwards and the expected timing of future recoveries or settlements of acquired assets with built-in losses. To the extent that information available as of the date of acquisition results in our determination that some portion of acquired net operating loss carryforwards cannot be utilized or assets with built-in losses are expected to be settled or recovered in future periods in which the ability to realize the benefits will be subject to the section 382 limitation, a deferred tax asset valuation allowance is established for the estimated amount of the deferred tax assets subject to the section 382 limitation. To the extent that information becomes available, during the first 12 months following the consummation of a business combination transaction, that results in changes in our initial estimates and assumptions regarding the expected utilization of acquired net operating loss carryforwards or the expected settlement or recovery of acquired assets with built-in losses subject to the section 382 limitation, an increase or decrease of the deferred tax asset valuation allowance will be recorded as an adjustment to bargain purchase gain or goodwill. To the extent that such information becomes available 12 months or more after the consummation of a business combination transaction, or additional information becomes available during the first 12 months as a result of changes in circumstances since the date of the consummation of a business combination transaction, an increase or decrease of the deferred tax asset valuation allowance will be recorded as an adjustment to deferred income tax expense (benefit).

Net Interest Income

Net interest income and net interest margin are analyzed in this discussion on a fully taxable equivalent (“FTE”) basis. The adjustment to convert net interest income to a FTE basis consists of dividing tax-exempt income by one minus the statutory federal income tax rate of 35%. The FTE adjustments to net interest income were $9.6 million in 2015, $10.7 million in 2014 and $8.6 million in 2013. No adjustments have been made in this analysis for income exempt from state income taxes or for interest expense deductions disallowed under the provisions of the IRC as a result of investments in certain tax-exempt securities.

2015 compared to 2014

Net interest income for 2015 increased 39.3% to $391.7 million compared to $281.2 million for 2014. Net interest margin decreased 33 basis points (“bps”) to 5.19% for 2015 compared to 5.52% for 2014. The increase in net interest income was primarily the result of the growth in average earning assets, which increased 48.3% to $7.55 billion for 2015 compared to $5.09 billion for 2014. The decrease in net interest margin for 2015 compared to 2014 was primarily due to the 39 bps decrease in yield on average earning assets, partially offset by a five bps decrease in rates paid on interest bearing liabilities.

Yields on average earning assets decreased to 5.55% for 2015 compared to 5.94% for 2014 primarily due to decreases in yield on our non-purchased loan and lease portfolio, our purchased loan portfolio and our aggregate investment securities portfolio.  The yield on our portfolio of non-purchased loans and leases decreased 10 bps to 5.00% for 2015 compared to 5.10% for 2014.  This decrease was primarily attributable to the extremely low interest rate environment experienced in recent years and continued pricing competition from many of our competitors.  Assuming the current low interest rate environment and pricing competition from many of our competitors continues, we expect yields on our non-purchased loan and lease portfolio will continue to decrease.  We have also continued to increase the percentage of variable rate loans in our non-purchased loan and lease portfolio in an effort to lower our interest rate risk.  At December 31, 2015, variable rate loans comprised 79.0% of our non-purchased loans and leases compared to 72.9% at December 31, 2014.  We expect to continue to increase the percentage of variable rate loans in our non-purchased loan and lease portfolio.  The yield on our purchased loan portfolio decreased 170 bps to 7.24% for 2015 compared to 8.94% for 2014.  This decrease was primarily attributable to the loans acquired in our Summit Bancorp, Inc. (“Summit”) and Intervest acquisitions, many of which did not contain evidence of credit deterioration on the date of acquisition and were priced at a lower yield compared to the then existing yield on our purchased loan portfolio.  This decrease in yield on purchased loans was partially offset by an increase in yield on certain purchased loans with evidence of credit deterioration on the date of acquisition due to upward revisions, during 2014 and 2015, of estimated cash flows as a result of recent evaluations of the expected performance of such loans.  The yield on our aggregate investment securities portfolio for 2015 decreased 12 bps compared to 2014.  This decrease in the yield on our aggregate investment securities portfolio was primarily the result of (i) a change in the composition of our investment securities portfolio to include a larger percentage of lower yielding taxable investment securities, which comprised 46.2% of the total average balance of investment securities in 2015 compared to 40.8% in 2014, and (ii) the low interest rate environment which has resulted in many issuers of investment securities, particularly tax-exempt municipal securities, calling higher-rate investment securities and refinancing such securities at lower interest rates.  Assuming this low interest rate environment continues, we would expect additional higher-rate tax-exempt investment securities to be called by their issuers and be refinanced at lower interest rates, likely resulting in continued decreases of the yield on our tax-exempt investment securities portfolio. Additionally, during the fourth quarter of 2015, we sold approximately $167 million of our investment securities portfolio in an effort to reduce that portfolio’s exposure to possible rising interest rates and to maintain our total assets below $10 billion at December 31, 2015.  To the extent we do not purchase investment securities to replace those securities sold in the fourth quarter of 2015, our interest income on our aggregate investment securities portfolio for 2016 is expected to decrease compared to 2015.  

The overall decrease in rates on average interest bearing liabilities, which decreased five bps for 2015 compared to 2014, was primarily due to a shift in the composition of total interest bearing liabilities to include a larger percentage of interest bearing deposits, partially offset by an increase in rates on interest bearing deposits, particularly time deposits.  Interest bearing deposits, which generally have lower rates than most of our other interest bearing liabilities, comprised 93.8% of total average interest bearing liabilities for 2015 compared to 89.9% for 2014.  The increase in interest bearing deposits as a percentage of total interest bearing liabilities was due, in part, to interest bearing deposits assumed in our Summit and Intervest acquisitions and growth in interest bearing deposits.  The increase in rates on interest bearing deposits, which increased eight bps for 2015 compared to 2014, is primarily due to a shift in the composition of interest bearing deposits to a larger percentage of time deposits, primarily as a result of our Intervest acquisition.  The average balance of time deposits increased from 30.0% of total average interest bearing deposits for 2014 to 37.4% for 2015.  Additionally, throughout much of 2014 and 2015, we increased deposit pricing, including the pricing of time deposits, in several target markets to fund growth in loans and leases.  To the extent we have future growth in loans and leases, we would expect

45

to increase deposit pricing in certain target markets to fund such growth.  Any such increase in deposit pricing is expected to result in increased deposit costs in future periods.

Our other borrowing sources include (i) repurchase agreements with customers (“repos”), (ii) other borrowings comprised primarily of Federal Home Loan Bank of Dallas (“FHLB”) advances, and, to a lesser extent, Federal Reserve Bank (“FRB”) borrowings and federal funds purchased, and (iii) subordinated debentures.  The rates on repos increased one bps in 2015 compared to 2014.  The rates on our other borrowing sources decreased 49 bps for 2015 compared to 2014. During 2015, we prepaid $150 million of fixed rate callable FHLB advances with a weighted average interest rate of 3.85%.  The weighted average interest rate on our remaining $40 million of fixed rate callable FHLB advances is 2.85%. The rates paid on our subordinated debentures, which are tied to a spread over the 90-day London Interbank Offered Rate (“LIBOR”) and reset periodically, increased 68 bps in 2015 compared to 2014.  This increase in rates on our subordinated debentures is primarily due to the $52.2 million of subordinated debentures assumed in our Intervest acquisition, which, net of amortization of the discount of the purchase accounting adjustments, had a weighted average interest rate of 4.27% at December 31, 2015.

The increase in average earning assets for 2015 compared to 2014 was due, in part, to an increase in the average balance of non-purchased loans and leases which increased $1.71 billion, or 53.6%, to $4.90 billion for 2015 compared to $3.19 billion for 2014 as we continued to experience strong growth in our originations of non-purchased loans and leases.  Additionally the average balance of purchased loans increased $763 million, or 69.5%, to $1.86 billion for 2015 compared to $1.10 billion for 2014, primarily as a result of the acquisition of Intervest. 

2014 compared to 2013

Net interest income for 2014 increased 39.1% to $281.2 million compared to $202.1 million for 2013. Net interest margin decreased 11 bps to 5.52% for 2014 compared to 5.63% for 2013. The increase in net interest income was primarily the result of the growth in average earning assets, which increased 41.8% to $5.09 billion for 2014 compared to $3.59 billion for 2013. The decrease in net interest margin for 2014 compared to 2013 was primarily due to the 21 bps decrease in yield on average earning assets, partially offset by an 11 bps decrease in rates paid on interest bearing liabilities.

Yields on average earning assets decreased to 5.94% for 2014 compared to 6.15% for 2013. The yield on our portfolio of non-purchased loans and leases decreased 38 bps to 5.10% for 2014 compared to 5.48% for 2013. This decrease was primarily attributable to the extremely low interest rate environment experienced in recent years and increased pricing competition from many of our competitors. The yield on our aggregate investment securities portfolio for 2014 decreased 43 bps compared to 2013. This decrease in the yield on our aggregate investment securities portfolio was primarily the result of (i) a change in the composition of our investment securities portfolio to include a larger percentage of lower yielding taxable investment securities, which comprised 40.8% of the total average balance of investment securities in 2014 compared to 36.1% in 2013, and (ii) the low interest rate environment which has resulted in many issuers of investment securities, particularly tax-exempt municipal securities, calling higher-rate investment securities and refinancing such securities at lower interest rates. Assuming this low interest rate environment continues, we expect additional higher-rate tax-exempt investment securities to be called by their issuers and be refinanced at lower interest rates, likely resulting in continued decreases of the yield on our tax-exempt investment securities portfolio. The yield on our purchased loan portfolio decreased nine bps to 8.94% for 2014 compared to 9.03% for 2013. This decrease was primarily attributable to the loans acquired in our Summit acquisition, many of which did not contain evidence of credit deterioration on the date of acquisition and were priced at a lower yield compared to the then existing yield on our purchased loan portfolio. This decrease in yield on purchased loans was partially offset by the increase in yield on certain purchased loans with evidence of credit deterioration on the date of acquisition due to upward revisions of estimated cash flows as a result of recent evaluations of the expected performance of such loans.

The overall decrease in rates on average interest bearing liabilities was primarily due to a shift in the composition of interest bearing liabilities. During 2014 the average balance of interest bearing deposits, which are generally one of our cheapest interest bearing funding sources, increased to 89.9% of total average interest bearing liabilities compared to 87.0% in 2013. The rate paid on our average interest bearing deposits of 23 bps for 2014 was unchanged compared to 2013. However, such rates have increased in recent quarters, increasing from 21 bps in the second quarter to 23 bps in the third quarter and 27 bps in the fourth quarter of 2014 as we have increased deposit pricing in several target markets to fund growth in non-purchased loans and leases. To the extent we have future growth in non-purchased loans and leases, we may again increase deposit pricing in certain target markets to fund such growth. Any such increase in deposit pricing is likely to result in increased deposit costs in future periods.

Our other borrowing sources include (i) repos, (ii) other borrowings comprised primarily of FHLB advances, and, to a lesser extent, FRB borrowings and federal funds purchased, and (iii) subordinated debentures. The rates on repos increased one bps in 2014 compared to 2013. The rates on our other borrowing sources, which consist primarily of fixed rate callable FHLB advances, increased six bps for 2014 compared to 2013. During the fourth quarter of 2014, we prepaid $90 million of fixed rate callable FHLB advances with a weighted average interest rate of 4.13%. At December 31, 2014, the weighted average interest rate on our remaining $190

46

million of fixed rate callable FHLB advances is approximately 3.64%. The rates paid on our subordinated debentures, which are tied to a spread over the 90-day LIBOR and reset periodically, decreased four bps in 2014 compared to 2013.

The increase in average earning assets for 2014 compared to 2013 was due, in part, to an increase in the average balance of non-purchased loans and leases of 35.0% to $3.19 billion for 2014 compared to $2.36 billion for 2013. Additionally the average balance of purchased loans increased 65.6% to $1.10 billion for 2014 compared to $663 million for 2013, primarily as a result of the acquisitions of Bancshares, Inc. (“Bancshares”) and Summit. The average balances of aggregate investment securities increased 42.0% to $798 million for 2014 compared to $562 million for 2013, primarily as a result of the investment securities acquired in the Summit acquisition.

The following table sets forth certain information relating to our net interest income for the years indicated. The yields and rates are derived by dividing interest income or interest expense by the average balance of the related assets or liabilities, respectively, for the periods shown. Average balances are derived from daily average balances for such assets and liabilities. The average balances of investment securities are computed based on amortized cost adjusted for unrealized gains and losses on investment securities AFS and other-than-temporary impairment writedowns. The yields on investment securities include amortization of premiums and accretion of discounts. The average balance of non-purchased loans and leases includes non-purchased loans and leases on which we have discontinued accruing interest. The yields on non-purchased loans and leases and purchased loans without evidence of credit deterioration at date of acquisition include late fees and amortization of certain deferred fees, origination costs and, for such purchased loans, accretion or amortization of any purchase accounting yield adjustment. The yields on purchased loans with evidence of credit deterioration at date of acquisition consist of accretion of the net present value of expected future cash flows using the effective yield method over the term of the loans and include late fees. Interest expense and rates on other borrowings are presented net of interest capitalized on construction projects. The interest expense on subordinated debentures assumed in the Intervest transaction includes the amortization of purchase accounting adjustments, using the level yield method, over the estimated holding period of approximately eight years.

The following table reflects how changes in the volume of interest earning assets and interest bearing liabilities and changes in interest rates have affected our interest income – FTE, interest expense and net interest income – FTE for the years indicated. Information is provided in each category with respect to changes attributable to (1) changes in volume (changes in volume multiplied by prior yield/rate); (2) changes in yield/rate (changes in yield/rate multiplied by prior volume); and (3) changes in both yield/rate and volume (changes in yield/rate multiplied by changes in volume). The changes attributable to the combined impact of yield/rate and volume have all been allocated to the changes due to volume.

Non-Interest Income

Our non-interest income consists primarily of service charges on deposit accounts, mortgage lending income, trust income, BOLI income, other income from purchased loans, net gains on investment securities, gains on sales of other assets and gains on merger and acquisition transactions.

2015 compared to 2014

Non-interest income for 2015 increased 23.7% to $105.0 million compared to $84.9 million for 2014. Non-interest income for 2015 included $2.3 million of tax-exempt income from BOLI death benefits, $5.5 million of gains on sales of investment securities and $6.3 million of gains on sales of certain purchased loans.  Non-interest income for 2014 included $4.7 million of tax-exempt bargain purchase gain on our Bancshares acquisition and $8.0 million of gain on termination of our FDIC loss share agreements.

Service charges on deposit accounts increased 7.9% to $28.7 million in 2015 compared to $26.6 million in 2014. This increase was primarily due to growth in the number of transaction accounts and the addition of deposit customers from our Summit acquisition, and, to a lesser extent, our Intervest and BCAR acquisitions.

Mortgage lending income increased 31.4% to $6.8 million in 2015 compared to $5.2 million in 2014. The volume of originations of mortgage loans available for sale increased 25.5% to $255 million in 2015 compared to $203 million in 2014.

Trust income increased 5.6% to $5.9 million in 2015 compared to $5.6 million in 2014. This increase in trust income was primarily due to growth in both corporate and personal trust income.

BOLI income increased 94.5% to $10.1 million in 2015 compared to $5.2 million in 2014 primarily due to the $2.3 million in BOLI death benefits received and $100 million of BOLI purchased in 2015, including $85 million in May and $15 million in

49

November.  In January 2016, we purchased an additional $42 million of BOLI.  BOLI income in the form of increases in cash surrender value help to offset a portion of employee benefit costs.

Other income from purchased loans was $26.1 million in 2015 compared to $14.8 million in 2014. Other income from purchased loans consists primarily of income recognized on purchased loan prepayments and payoffs that are not considered yield adjustments. Because other income from purchased loans may be significantly affected by loan payments and payoffs, this income item may vary significantly from period to period.

Net gains on investment securities were $5.5 million in 2015 from the sale of approximately $197 million of investment securities, compared to net gains of $0.1 million in 2014 from the sale of approximately $56 million of investment securities. During 2015, proceeds totaling approximately $203 million from the sales of investment securities were used to prepay $150 million of our highest rate callable FHLB advances.  These transactions were executed for various reasons, including to reduce interest rate risk, to increase secondary sources of liquidity, to more efficiently allocate capital, and to help maintain our total assets below $10 billion at December 31, 2015.

Gains on sales of other assets were $14.8 million in 2015 compared to $6.0 million in 2014. Included in gains on sales of other assets in 2015 was $6.3 million of gains on the sale of approximately $13 million of certain purchased loans.

In 2014 we recorded a tax-exempt bargain purchase gain of $4.7 million on our Bancshares acquisition.  We had no bargain purchase gain in 2015.

During 2014, we entered into agreements with the FDIC terminating the loss share agreements for all seven of our FDIC-assisted acquisitions, resulting in a gain of $8.0 million included in “other” non-interest expense in 2014. All rights and obligations of the parties under the FDIC loss share agreements, including the clawback provisions, were eliminated under these termination agreements.  As a result, all recoveries, gains, charge-offs, losses and expenses related to assets previously covered under loss share are recognized entirely by us and contributed, in part, to the increases in other income from purchased loans and gains on sales of other assets in 2015 compared to 2014.

2014 compared to 2013

Non-interest income for 2014 increased 11.6% to $84.9 million compared to $76.1 million for 2013. Non-interest income for 2014 included $4.7 million of tax-exempt bargain purchase gain on our Bancshares acquisition and $8.0 million of gain on termination of our FDIC loss share agreements. Non-interest income for 2013 included $5.2 million of tax-exempt bargain purchase gain on our acquisition of The First National Bank of Shelby (“First National Bank”).

Service charges on deposit accounts increased 22.9% to $26.6 million in 2014 compared to $21.6 million in 2013. This increase was primarily due to growth in the number of transaction accounts and the addition of deposit customers from recent acquisitions.

Mortgage lending income decreased 7.8% to $5.2 million in 2014 compared to $5.6 million in 2013. Originations of mortgage loans for sale, including both originations for home purchases and refinancings of existing mortgages, decreased 5.6% to $203 million in 2014 compared to $209 million in 2013. Mortgage originations for home purchases were 68% of 2014 origination volume compared to 52% in 2013. Refinancing of existing mortgages accounted for 32% of 2014 origination volume compared to 48% in 2013.

Trust income increased 36.5% to $5.6 million in 2014 compared to $4.1 million in 2013. This increase in trust income was primarily due to new trust customers added as a result of our acquisitions, primarily our First National Bank acquisition.

BOLI income increased 14.5% to $5.2 million in 2014 compared to $4.5 million in 2013 primarily due to the BOLI acquired in the First National Bank and Summit acquisitions.

Net gains on investment securities were $0.1 million in 2014 from the sale of approximately $55.6 million of investment securities, compared to net gains of $0.2 million in 2013 from the sale of approximately $0.8 million of investment securities.

Gains on sales of other assets were $6.0 million in 2014 compared to $9.4 million in 2013. The gains on sales of other assets for both 2014 and 2013 were primarily due to gains on sales of purchased foreclosed assets. Because the Day 1 Fair Values of purchased foreclosed assets include a net present value component, which is not accreted into income over the expected holding period of such assets, the sale of purchased foreclosed assets has typically resulted in gains on such sales.

50

Accretion of our FDIC loss share receivable, net of amortization of our FDIC clawback payable resulted in net expense of $0.6 million in 2014 compared to $7.2 million of income during 2013. During the fourth quarter of 2014, we entered into agreements with the FDIC terminating the loss share agreements for all seven of our FDIC-assisted acquisitions, resulting in a gain of $8.0 million included in “other” non-interest income. All rights and obligations of the parties under the FDIC loss share agreements, including the clawback provisions, have been eliminated under these termination agreements.

Other income from purchased loans was $14.8 million in 2014 compared to $13.2 million in 2013. Other income from purchased loans consists primarily of income recognized on purchased loan prepayments and payoffs that are not considered yield adjustments. Because other income from purchased loans may be significantly affected by loan payments and payoffs, this income item may vary significantly from period to period.

On March 5, 2014, we completed our Bancshares acquisition in a transaction valued at $21.5 million. This acquisition resulted in a tax-exempt bargain purchase gain of $4.7 million in 2014.

On July 31, 2013, we completed our First National Bank acquisition in a transaction valued at $68.5 million. This acquisition resulted in a tax-exempt bargain purchase gain of $5.2 million in 2013.

Non-Interest Expense

Non-interest expense consists of salaries and employee benefits, net occupancy and equipment expense and other operating expenses.

2015 compared to 2014

Non-interest expense for 2015 increased 15.0% to $191.0 million compared to $166.0 million for 2014. Non-interest expense for 2015 included $8.9 million in penalties from prepaying $150 million of our highest cost fixed-rate callable FHLB advances, $2.2 million of severance cost associated with the elimination of the New York lending operations acquired in our Intervest acquisition, which we refer to as Stabilized Properties Group (or SPG), and the consolidation of the remaining servicing team of the SPG into our Real Estate Specialties Group (“RESG”), approximately $6.7 million of acquisition-related as systems conversion expenses and $1.0 million of software and contract termination charges.  Non-interest expense for 2014 included $8.1 million of FHLB prepayment penalties, approximately $4.7 million of acquisition-related and systems conversion expenses, and $5.6 million of software and contract termination charges.  Our efficiency ratio for 2015 was 38.4% compared to 45.3% for 2014. Our “core” efficiency ratio for 2015 was 35.7% compared to 41.6% for 2014. The calculation of our “core” efficiency ratio and the reconciliation to GAAP is included in the following tables in the MD&A.

51

Salaries and employee benefits, our largest component of non-interest expense, increased 14.4% to $88.0 million in 2015 from $76.9 million in 2014. We had 1,642 full-time equivalent employees at December 31, 2015, an increase of 11.0% from 1,479 full-time equivalent employees at December 31, 2014.

Net occupancy and equipment expense increased 29.6% to $31.2 million in 2015 compared to $24.1 million in 2014. At December 31, 2015, we had 174 offices, including 81 in Arkansas, 28 in Georgia, 25 in North Carolina, 22 in Texas, 10 in Florida, three in Alabama, two offices each in South Carolina and New York and one office in California. At December 31, 2014, we had 159 offices, including 81 in Arkansas, 28 in Georgia, 21 in Texas, 17 in North Carolina, five in Florida, three in Alabama, two in South Carolina and one office each in New York and California.

Other operating expenses increased 10.4% to $71.8 billion in 2015 compared to $65.0 million in 2014, primarily as a result of (i) $12.6 million of professional and outside services expense in 2015, compared to $10.8 million in 2014, (ii) $5.1 million of FDIC and state assessments and insurance expense in 2015, compared to $3.3 million in 2014, (iii) $8.9 million of loan collection and repossession expenses and writedowns of foreclosed assets in 2015 compared to $4.6 million in 2014 and (iv) $6.7 million in amortization of intangibles in 2015 compared to $5.0 million in 2014.  These increases were partially offset by decreases in software expense to $2.6 million in 2015 compared to $5.0 million in 2014 and a decrease in “other” non-interest expense to $8.7 million in 2015 compared to $12.0 million in 2014.  The increases in professional and outside services, FDIC and state assessments and insurance expense and amortization of intangibles is primarily the result of our acquisitions of Intervest and BCAR and, to a lesser extent, our pending acquisitions of C&S and C1.  The increase in loan collection and repossession expenses and writedowns of foreclosed assets was due, in part, to the termination in late 2014 of all loss share agreements with the FDIC.  The decrease in software expense was primarily attributable to the reduced run rate associated with our conversion to a new core banking systems in 2014.  The decrease in “other” is primarily due to $5.6 million of contract termination costs in 2014 that were directly attributable to the core systems conversion.

2014 compared to 2013

Non-interest expense for 2014 increased 31.7% to $166.0 million compared to $126.1 million for 2013. Our efficiency ratio for 2014 was 45.35% compared to 45.32% for 2013.

Salaries and employee benefits, our largest component of non-interest expense, increased 18.6% to $76.9 million in 2014 from $64.8 million in 2013. We had 1,479 full-time equivalent employees at December 31, 2014, an increase of 20.9% from 1,223 full-time equivalent employees at December 31, 2013.

Net occupancy and equipment expense for 2014 increased 28.8% to $24.1 million in 2014 compared to $18.7 million in 2013. At December 31, 2014, we had 159 offices, including 81 in Arkansas, 28 in Georgia, 21 in Texas, 17 in North Carolina, five in Florida, three in Alabama, two in South Carolina and one office each in New York and California. At December 31, 2013, we had 131 offices, including 66 in Arkansas, 28 in Georgia, 15 in North Carolina, 13 in Texas, four in Florida, three in Alabama, and one office each in South Carolina and New York.

Other operating expenses increased 52.9% to $65.0 million in 2014 compared to $42.5 million in 2013, primarily as a result of (i) $8.1 million of FHLB prepayment penalty resulting from prepaying $90 million of our highest cost fixed rate callable FHLB advances; (ii) $10.8 million of professional and outside services expense in 2014, compared to $6.7 million in 2013, (iii) $5.0 million of amortization of intangibles in 2014 compared to $2.8 million in 2013 and (iv) increases in “other” expenses of $4.7 million. The increases in professional and outside services expense and “other” expense in 2014 compared to 2013 is primarily related to our conversion of our core banking systems, including contract termination costs of approximately $5.6 million directly attributable to these systems conversion.

We use the core efficiency ratio, which is a non-GAAP financial measure, to better evaluate the efficiency of our operations.  This core efficiency ratio excludes certain revenues and expenses that we deem to be “non-core.”  We believe our core efficiency ratio provides useful supplemental information that contributes to a better understanding of our financial results.  This non-GAAP measure should not be viewed as a substitute for financial results determined in accordance with GAAP, nor is it necessarily comparable to non-GAAP measures presented by other companies.  The reconciliation of our core efficiency ratio to the most directly comparable GAAP financial measure is included in the following table.

Income Taxes

Our provision for income taxes was $94.5 million in 2015 compared to $53.9 million in 2014 and $40.1 million in 2013. Our effective income tax rates were 34.2% for 2015, 31.2% for 2014 and 30.6% for 2013. The increase in the effective tax rate for 2015 compared to 2014 is primarily the result of a decrease in tax-exempt income as a percent of total income.  The effective tax rates for all periods were also affected by various other factors including amounts of non-taxable income and non-deductible expenses. A reconciliation between the statutory federal income tax rates and our effective income tax rates for the years ended December 31, 2015, 2014 and 2013 is included in Note 14 to the Consolidated Financial Statements included elsewhere in this Annual Report on Form 10-K.

Analysis of Financial Condition

Loan and Lease Portfolio

At December 31, 2015, our total loan and lease portfolio was $8.33 billion, an increase of 62.5% from $5.13 billion at December 31, 2014. As of December 31, 2015, our total loan and lease portfolio consisted of 89.2% real estate loans, 3.5% commercial and industrial loans, 0.4% consumer loans, 1.8% direct financing leases and 5.1% other loans. Real estate loans, our largest category of loans, include all loans made to finance the development of real property construction projects, provided such loans are secured by real estate, and all other loans secured by real estate as evidenced by mortgages or other liens.

Included in “other” loans at December 31, 2015, 2014 and 2013 (none at December 31, 2012 or 2011) are loans totaling $394 million, $61 million and $32 million, respectively, that were originated to acquire promissory notes from non-depository financial institutions and are typically collateralized by an assignment of the promissory note and all related note documents including mortgages, deeds of trust, etc.  While the loans are considered “other” loans in accordance with FDIC Call Report instructions, we underwrite these lending transactions based on the fundamentals of the underlying collateral, repayment sources and guarantors, among others, consistent with other similar lending transactions.

The amount and type of our real estate loans at December 31, 2015 based on the metropolitan statistical area (“MSA”) and other geographic areas in which the principal collateral is located are reflected in the following table. Data for individual states or MSAs is separately presented when aggregate real estate loans in that state or MSA exceed $10 million.

Many of our construction and development loans provide for the use of interest reserves. When we underwrite construction and development loans, we consider the expected total project costs, including hard costs such as land, site work and construction costs and soft costs such as architectural and engineering fees, closing costs, leasing commissions and construction period interest. Based on the total project costs and other factors, we determine the required borrower cash equity contribution and the maximum amount we are willing to loan. In the vast majority of cases, we require that all of the borrower’s cash equity contribution be contributed prior to any significant loan advances. This ensures that the borrower’s cash equity required to complete the project will be available for such purposes. As a result of this practice, the borrower’s cash equity typically goes toward the purchase of the land and early stage hard costs and soft costs. This results in our funding the loan later as the project progresses, and accordingly, we typically fund the majority of the construction period interest through loan advances. However, when we initially determine the borrower’s cash equity requirement, we typically require the borrower’s cash equity to cover a majority, or all, of the soft costs, including an amount equal to construction period interest, and an appropriate portion of the hard costs. During 2015, we advanced construction period interest totaling approximately $57.6 million on construction and development loans. While we advanced these sums as part of the funding process, we believe that the borrowers in effect had in most cases already provided for these sums as part of their initial equity contribution. Specifically, the maximum committed balance of all construction and development loans which provide for the use of interest reserves at December 31, 2015 was $7.38 billion, of which $2.47 billion was outstanding at December 31, 2015 and $4.91 billion remained to be advanced. The weighted average loan-to-cost on such loans, assuming such loans are ultimately fully advanced, will be approximately 50%, which means that the weighted average cash equity contributed on such loans, assuming such loans are ultimately fully advanced, will be approximately 50%. The weighted average final loan-to-value ratio on such loans, based on the most recent appraisals and assuming such loans are ultimately fully advanced, is expected to be approximately 44%.

The following table reflects total loans and leases grouped by remaining maturities at December 31, 2015 by type and by fixed or floating interest rates. This table is based on actual maturities and does not reflect amortizations, projected paydowns or the earliest repricing for floating rate loans. Many loans have principal paydowns scheduled in periods prior to the period in which they mature. In addition many variable rate loans are subject to repricing in periods prior to the period in which they mature. Because income on purchased loans with evidence of credit deterioration on the date of acquisition is recognized by accretion of the discount of estimated cash flows, such loans are not considered to be floating or adjustable rate loans and are reported below as fixed rate loans.

The following table reflects total loans and leases as of December 31, 2015 grouped by expected amortizations, expected paydowns or the earliest repricing opportunity for floating rate loans. This cash flow or repricing schedule approximates our ability to reprice the outstanding principal of loans and leases either by adjusting rates on existing loans and leases or reinvesting principal cash flow in new loans and leases. For non-purchased loans and leases and purchased loans without evidence of credit deterioration on the date of acquisition, the table below reflects the earliest contractual repricing period. For purchased loans with evidence of credit deterioration at the date of acquisition, the table below reflects estimated cash flows based on the most recent evaluation of each individual loan. Because income on purchased loans with evidence of credit deterioration on the date of acquisition is recognized by accretion of the discount of estimated cash flows, such loans are not considered to be floating or adjustable rate loans and are reported below as fixed rate loans.

(1) We have included a floor rate in many of our non-purchased loans and leases. As a result of such floor rates, loans and leases may not immediately reprice in a rising rate environment if the interest rate index and margin on such loans and leases continue to result in a computed interest rate less than the applicable floor rate. The earnings simulation model results included elsewhere in this Annual Report on Form 10-K includes consideration of the effect of all interest rate floors and ceilings in loans and leases.

At December 31, 2015, approximately 95% of our floating rate loans are tied to three major benchmark interest rates, the 1-month LIBOR, 3-month LIBOR and Wall Street Journal Prime interest rate. The following table is a summary of our floating rate loan portfolio and contractual interest rate indices.

Nonperforming Assets

Nonperforming assets consist of (1) nonaccrual loans and leases, (2) accruing loans and leases 90 days or more past due, (3) troubled debt structurings (“TDRs”) and (4) real estate or other assets that have been acquired in partial or full satisfaction of loan or lease obligations or upon foreclosure. Purchased loans are not included in the following table as nonperforming assets, except for their inclusion in total assets, but are analyzed and discussed elsewhere in this MD&A.

The accrual of interest on non-purchased loans and leases and purchased loans without evidence of credit deterioration at the date of acquisition is discontinued when, in management’s opinion, the borrower or lessee may be unable to meet payments as they become due. We generally place a loan or lease, excluding purchased loans with evidence of credit deterioration on the date of acquisition, on nonaccrual status when such loan or lease is (i) deemed impaired or (ii) 90 days or more past due, or earlier when doubt exists as to the ultimate collection of payments. We may continue to accrue interest on certain loans or leases contractually past due 90 days or more if such loans or leases are both well secured and in the process of collection. At the time a loan or lease is placed on nonaccrual status, interest previously accrued but uncollected is reversed and charged against interest income. Nonaccrual loans and leases are generally returned to accrual status when payments are less than 90 days past due and we reasonably expect to collect all payments. If a loan or lease is determined to be uncollectible, the portion of the principal determined to be uncollectible will be charged against the ALLL. Loans for which the terms have been modified and for which (i) the borrower is experiencing financial difficulties and (ii) we have granted a concession to the borrower are considered TDRs and are included in impaired loans and leases. Income on nonaccrual loans or leases, including impaired loans and leases but excluding certain TDRs which continue to accrue interest, is recognized on a cash basis when and if actually collected.

(1) Repossessed personal properties and real estate acquired through or in lieu of foreclosure, excluding purchased foreclosed assets, are initially recorded at the lesser of current principal investment or estimated market value less estimated cost to sell at the date of repossession or foreclosure. Purchased foreclosed assets are initially recorded at Day 1 Fair Values. Valuations of these assets are periodically reviewed by management with the carrying value of such assets adjusted through non-interest expense to the then estimated market value net of estimated selling costs, if lower, until disposition.

(2) Excludes purchased loans, except for their inclusion in total assets.

If an adequate current determination of collateral value has not been performed, once a loan or lease is considered impaired, we seek to establish an appropriate value for the collateral. This assessment may include (i) obtaining an updated appraisal, (ii) obtaining one or more broker price opinions or comprehensive market analyses, (iii) internal evaluations or (iv) other methods deemed appropriate considering the size and complexity of the loan and the underlying collateral. On an ongoing basis, typically at least quarterly, we evaluate the underlying collateral on all impaired loans and leases and, if needed, due to changes in market or property conditions, the underlying collateral is reassessed and the estimated fair value is revised. The determination of collateral value includes any adjustments considered necessary related to estimated holding period and estimated selling costs.

At December 31, 2015, we had reduced the carrying value of our loans and leases deemed impaired (all of which were included in nonaccrual loans and leases) by $7.8 million to the estimated fair value of such loans and leases of $9.3 million. The adjustment to reduce the carrying value of impaired loans and leases to estimated fair value consisted of $6.5 million of partial charge-offs and $1.3 million of specific loan and lease loss allocations. These amounts do not include our $8.1 million of impaired purchased loans at December 31, 2015.

As of December 31, 2015, 2014 and 2013, we had identified purchased loans where we had determined it was probable that we would be unable to collect all amounts according to the contractual terms thereof (for purchased loans without evidence of credit deterioration at date of acquisition) or the expected performance of such loans had deteriorated from our performance expectations established in conjunction with the determination of the Day 1 Fair Values or since our most recent review of such portfolio’s performance (for purchased loans with evidence of credit deterioration at date of acquisition). As a result, we recorded net charge-offs totaling $2.5 million during 2015, $3.2 million during 2014, and $4.7 million during 2013 for such loans. We also recorded $2.5 million during 2015, $3.2 million during 2014, and $4.7 million during 2013 of provision for loan and lease losses to cover these charge-offs. Also, we recorded $1.2 million of additional provision in 2015 (none in 2014 or 2013) to absorb probable incurred losses in our purchased loan portfolio that had not previously been charged off.  Additionally, we transferred certain of these purchased loans to foreclosed assets. As a result of these actions, we had $8.1 million of impaired purchased loans at December 31, 2015, $14.0 million of impaired purchased loans at December 31, 2014, and $46.2 million of impaired purchased loans at December 31, 2013.  

Allowance and Provision for Loan and Lease Losses

Our ALLL was $60.9 million at December 31, 2015 compared to $52.9 million at December 31, 2014 and $42.9 million at December 31, 2013. At December 31, 2015, we allocated $1.2 million of ALLL to our purchased loan portfolio. At December 31, 2014 and 2013 we had no ALLL for our purchased loan portfolio because all losses on purchased loans had been previously charged off. Excluding purchased loans, our ALLL as a percentage of nonperforming loans and leases was 452% at December 31, 2015, compared to 251% at December 31, 2014 and 492% at December 31, 2013. Our practice is to charge off any estimated loss as soon as we are able to identify and reasonably quantify such potential loss. Accordingly, only a small portion of our ALLL is needed for potential losses on nonperforming loans. While we believe the current allowance is appropriate, changing economic and other conditions may require future adjustments to the ALLL.

The amount of provision to the ALLL is based on our analysis of the adequacy of the ALLL utilizing the criteria discussed in the Critical Accounting Policies caption of this MD&A. The provision for loan and lease losses for 2015 was $19.4 million, including $15.7 million for non-purchased loans and leases and $3.7 million for purchased loans, compared to $16.9 million in 2014, including $13.7 million for non-purchased loans and leases and $3.2 million for purchased loans, and $12.1 million in 2013, including $7.4 million for non-purchased loans and leases and $4.7 million for purchased loans. The increase in our provision for non-purchased loans and leases in 2015 compared to 2014 and in 2014 compared to 2013 was primarily the result of provision necessary to cover the growth in our loan and lease portfolio during 2015 and 2014.  Our provision for purchased loans for 2015 included $1.2 million of provision to cover probable incurred losses within our purchased loan portfolio and $2.5 million of provision to provide for the net charge-offs of purchased loans.  Our provision for purchased loans for 2014 and 2013 was the amount needed to provide for the net charge-offs of purchased loans.

The following table sets forth the sum of the amounts of the ALLL as of the dates indicated. These allowance amounts have been computed using our internal grading system, specific impairment analyses, specific special reserve analyses and qualitative factor allocations. The amounts shown are not necessarily indicative of the actual future losses that may occur within particular categories. Prior to December 31, 2015, we had no allocation of our allowance to purchased loans because all losses had been charged off on purchased loans where we had determined it was probable that we would be unable to collect all amounts according to the contractual terms thereof (for purchased loans without evidence of credit deterioration at date of acquisition) or whose performance had deteriorated from our expectations established in conjunction with the deterioration of the Day 1 Fair Values (for purchased loans with evidence of credit deterioration at date of acquisition).

We maintain an internally classified loan and lease list that, along with the list of nonaccrual loans and leases, the list of impaired loans and leases, the list of loans and leases with specific reserves and the qualitative factor allocations, helps us assess the overall quality of the loan and lease portfolio and the adequacy of our ALLL. Loans and leases classified as “substandard” have clear and defined weaknesses such as highly leveraged positions, unfavorable financial ratios, uncertain repayment sources or poor financial

68

condition which may jeopardize collectability of the loan or lease. Loans and leases classified as “doubtful” have characteristics similar to substandard loans and leases, but also have an increased risk that a loss may occur or at least a portion of the loan or lease may require a charge-off if liquidated. Although loans and leases classified as substandard do not duplicate loans and leases classified as doubtful, both substandard and doubtful loans and leases may include some that are past due at least 90 days, are on nonaccrual status or have been restructured. Loans and leases classified as “loss” are charged off. At December 31, 2015 substandard loans and leases, excluding purchased loans, not designated as impaired, nonaccrual or 90 days past due, totaled $1.5 million, compared to $11.7 million at December 31, 2014 and $12.0 million at December 31, 2013. No loans or leases were designated as doubtful or loss at December 31, 2015, 2014 or 2013.

Administration of our lending function is the responsibility of the Chief Executive Officer (“CEO”), Chief Credit Officer (“CCO”), Chief Lending Officer (“CLO”), Director of Community Bank Lending (“Dir-CBL”) and certain other lenders. Such officers and lenders perform their lending duties subject to the oversight and policy direction of our board of directors and the directors’ loan committee. Loan or lease authority is granted to the CEO, CCO, CLO and Dir-CBL by the board of directors. The loan or lease authorities of other lending officers are granted by the directors’ loan committee on the recommendation of appropriate senior officers.

Loans and leases and aggregate loan and lease relationships exceeding $10 million up to the limits established by our board of directors must be approved by the directors’ loan committee. The directors’ loan committee consists of five or more directors and three of our senior lenders. At least quarterly the board of directors reviews summary reports of past due loans and leases, internally classified and watch list loans and leases, activity in the Company’s ALLL and various other loan and lease reports.

Our compliance and loan review officers are responsible for our bank subsidiary’s compliance and loan review functions. Periodic reviews are scheduled for the purpose of evaluating asset quality and effectiveness of loan and lease administration. The compliance and loan review officers prepare reports that identify deficiencies, establish recommendations for improvement and outline management’s proposed action plan for curing the identified deficiencies. These reports are provided to and reviewed by our audit committee.

Investment Securities

At December 31, 2015, 2014 and 2013, we classified all of our investment securities portfolio as available for sale. Accordingly, our investment securities are reported at estimated fair value with the unrealized gains and losses, net of tax, reported as a separate component of stockholders’ equity and included in other comprehensive income (loss).

The following table presents the amortized cost and estimated fair value of investment securities as of the dates indicated. Our holdings of “other equity securities” include FHLB and First National Banker’s Bankshares, Inc. (“FNBB”) shares which do not have readily determinable fair values and are carried at cost.

Our investment securities portfolio is reported at estimated fair value, which included gross unrealized gains of $14.0 million and gross unrealized losses of $1.2 million at December 31, 2015; gross unrealized gains of $24.4 million and gross unrealized losses of $1.2 million at December 31, 2014; and gross unrealized gains of $8.6 million and gross unrealized losses of $14.6 million at December 31, 2013. We believe that all of the unrealized losses on individual investment securities at December 31, 2015, 2014 and 2013 are the result of fluctuations in interest rates and do not reflect deterioration in the credit quality of our investments. Accordingly, we consider these unrealized losses to be temporary in nature. We do not have the intent to sell these investment securities and more likely than not, would not be required to sell these investment securities before fair value recovers to amortized cost.

We recognized premium amortization, net of discount accretion, of $0.4 million during 2015, $0.6 million during 2014 and $0.5 million during 2013. Any premium amortization or discount accretion is considered an adjustment to the yield of our investment securities.

We had net gains of $5.5 million in 2015 from the sale of approximately $197 million of investment securities, compared to net gains of $0.1 million in 2014 from the sale of approximately $56 million of investment securities and net gains of $0.2 million in 2013 from the sale of approximately $1 million of investment securities.  Investment securities totaling $160 million in 2015, $103 million in 2014 and $86 million in 2013 matured or were called by the issuer. We purchased investment securities totaling $92 million in 2015, $56 million in 2014 and $141 million in 2013.

We invest in securities we believe offer good relative value at the time of purchase, and we will, from time to time, reposition our investment securities portfolio. In making decisions to sell or purchase securities, we consider credit quality, call features, maturity dates, relative yields, current market factors, interest rate risk and other relevant factors. During 2015 we used proceeds from the sales of investment securities to prepay $150 million of our highest rate callable FHLB advances.  These transactions were executed for various reasons, including to reduce interest rate risk, to increase secondary sources of liquidity, to more efficiently allocate capital and to help maintain our total assets below $10 billion at December 31, 2015.

(5) Includes all securities that are not rated or securities that are not rated but that have a rated credit enhancement where we have ignored such credit enhancement. For these securities, we have performed our own evaluation of the security and/or the underlying issuer and believe that such security or its issuer would warrant a credit rating of investment grade (i.e., Baa3 or better by Moody’s or BBB- or better by Fitch or S&P or a comparable rating by other nationally-recognized credit rating agencies).

The following table reflects the expected maturity distribution of our investment securities, at estimated fair value, at December 31, 2015 and weighted-average yields (for tax-exempt obligations on a FTE basis) of such securities. The maturity for all investment securities is shown based on each security’s contractual maturity date, except (1) equity securities with no contractual maturity date which are shown in the longest maturity category, (2) U.S. Government agency securities collateralized by residential mortgages are allocated among various maturities based on an estimated repayment schedule utilizing Bloomberg median prepayment speeds based on interest rate levels at December 31, 2015, and (3) callable investment securities for which the Company has received notification of call are included in the maturity category in which the call occurs or is expected to occur. Actual maturities will differ from contractual maturities because issuers may have the right to call or prepay obligations with or without call or prepayment penalties. The weighted-average yields – FTE are calculated based on the coupon rate and amortized cost for such securities and do not include any projected discount accretion or premium amortization.

Deposits

Our lending and investing activities are funded primarily by deposits. On February 10, 2015, we assumed $1.18 billion of deposits as a result of our acquisition of Intervest, and on August 5, 2015, we assumed $289 million of deposits as a result of our acquisition of BCAR.  On May 16, 2014, we assumed $970 million of deposits as a result of our acquisition of Summit.  Additionally, we continued to grow our existing deposit base to fund growth of our non-purchased loans and leases.  Excluding deposits acquired in acquisitions, our deposits increased $1.00 billion in 2015 and $554 million in 2014. The amount and type of deposits outstanding as of the dates indicated and their respective percentage of total deposits are reflected in the following table.

The increase in our time deposits, which comprised 30.6% of total deposits at December 31, 2015 compared to 26.5% at December 31, 2014, is primarily the result of deposits assumed in our Intervest acquisition.  At December 31, 2015, we had outstanding brokered deposits of $677 million, compared to $210 million at December 31, 2014 and $49 million at December 31, 2013.

Other Interest Bearing Liabilities

We also rely on other interest bearing liabilities to fund our lending and investing activities. Such liabilities consist of repurchase agreements with customers, other borrowings (primarily FHLB advances and, to a lesser extent, FRB borrowings and federal funds purchased) and subordinated debentures.

The following table reflects the average balance and average rate paid for each category of other interest bearing liabilities for the years indicated.

(1) Included in other borrowings at December 31, 2014 are FHLB advances that contain quarterly call features and mature as follows: 2017, $20 million at 3.16% weighted-average rate; and 2018, $20 million at 2.53% weighted-average rate.

73

The decrease in other borrowings during 2015 compared to 2014 was due to our prepaying of $30 million in FHLB borrowings during the first quarter of 2015 and $120 million of FHLB borrowings during the fourth quarter of 2015.  The increase in subordinated debentures is due to $52.2 million (net of purchase accounting adjustments) of subordinated debentures assumed in the Intervest transaction.

Capital Resources and Liquidity

Capital Resources

Subordinated Debentures. We own eight 100%-owned finance subsidiary business trusts – Ozark Capital Statutory Trust II (“Ozark II”), Ozark Capital Statutory Trust III (“Ozark III”), Ozark Capital Statutory Trust IV (“Ozark IV”), Ozark Capital Statutory Trust V (“Ozark V”) (collectively, the “Ozark Trusts”), and as a result of our Intervest acquisition, Intervest Statutory Trust II (“Intervest II”), Intervest Statutory Trust III (“Intervest III”), Intervest Statutory Trust IV (“Intervest IV”) and Intervest Statutory Trust V (“Intervest V”), (collectively, the “Intervest Trusts”; and together with Ozark Trusts, the “Trusts”). At December 31, 2015, we had the following issues of trust preferred securities and subordinated debentures owed to the Trusts.

On February 10, 2015, in conjunction with the Intervest acquisition, the Company acquired the Intervest Trusts with outstanding subordinated debentures totaling $56.7 million and related trust preferred securities totaling $55.0 million. On the date of such acquisition, the Company recorded the assumed subordinated debentures owed to the Intervest Trusts at estimated fair value of $52.2 million, based on an independent third party valuation, to reflect a current market interest rate for comparable obligations. The fair value adjustment of $4.5 million is being amortized, using a level-yield methodology over the estimated holding period of approximately eight years, as an increase in interest expense of the subordinated debentures owed to the Intervest Trusts.

Our subordinated debentures and securities generally mature 30 years after issuance and may be prepaid at par, subject to regulatory approval, on or after approximately five years from the date of issuance, or at an earlier date upon certain changes in tax laws, investment company laws or regulatory capital requirements. These subordinated debentures and the related trust preferred securities provide us additional regulatory capital to support our expected future growth and expansion. See “Capital Compliance–Regulatory Capital” elsewhere in the MD&A for a discussion of our trust preferred securities and their continued inclusion in, or exclusion from, our regulatory capital in future periods.

We may need to raise additional capital in the future to provide us with sufficient capital resources and liquidity to meet our commitments and business needs. As a publicly traded company, a likely source of additional funds is the capital markets, which can provide us with funds through the public issuance of equity, both common and preferred stock, and the issuance of senior debt and/or subordinated debentures. We have an effective shelf registration statement on file with the SEC which provides us increased flexibility and more efficient access to the public debt and equity markets if needed. Our ability to raise additional capital, if needed, will depend on, among other things, conditions in the capital markets at that time, which are outside of our control, and our financial performance.

Common Stockholders’ Equity and Non-GAAP Financial Measures. We use non-GAAP financial measures, specifically tangible common stockholders’ equity, tangible common stockholders’ equity to total tangible assets, tangible book value per common share and return on average tangible common stockholders’ equity as important measures of the strength of our capital and our ability to generate earnings on tangible common equity invested by our shareholders. We believe presentation of these non-GAAP financial measures provides useful supplemental information that contributes to a proper understanding of our financial results and capital levels. These non-GAAP disclosures should not be viewed as a substitute for financial 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 these non-GAAP financial measures to the most directly comparable GAAP financial measures are included in the following tables.

Common Stock Dividend Policy. In 2015 we paid dividends of $0.55 per common share, compared to $0.47 per common share in 2014 and $0.36 per common share in 2013. On January 4, 2016, our board of directors approved a dividend of $0.15 per common share that was paid on January 22, 2016 to shareholders of record on January 15, 2016. The determination of future dividends on our common stock will depend on conditions existing at that time and approval of our board of directors. See Note 19 to the Consolidated Financial Statements included elsewhere in this Annual Report on Form 10-K for a discussion of dividend restrictions.

Capital Compliance

Regulatory Capital. The Company is subject to various regulatory capital requirements administered by federal and state banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s financial condition and results of operations. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company must meet specific capital guidelines that involve quantitative measures of the Company’s assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. The Company’s capital amounts and classification are also subject to qualitative judgments by the regulators about component risk weightings and other factors.

The FDIC and other federal banking regulators revised the risk-based capital requirements applicable to bank holding companies and insured depository institutions, including the Company and the Bank, to make them consistent with agreements that were reached by the Basel Committee on Banking Supervision (“Basel III”) and certain provisions of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Basel III Rules”). The Basel III Rules became effective for the Company and the Bank on January 1, 2015 (subject to a phase-in period for certain provisions). The Basel III Rules require the maintenance of minimum amounts and ratios of common equity tier 1 capital, tier 1 capital and total capital to risk-weighted assets, and of tier 1 capital to adjusted quarterly average assets.

Under the Basel III Rules, common equity tier 1 capital consists of common stock and paid-in capital (net of treasury stock) and retained earnings. Common equity tier 1 capital is reduced by goodwill, certain intangible assets, net of associated deferred tax liabilities, deferred tax assets that arise from tax credit and net operating loss carryforwards, net of any valuation allowance, and certain other items as specified by the Basel III Rules.

Tier 1 capital includes common equity tier 1 capital and certain additional tier 1 items as provided under the Basel III Rules. Our tier 1 capital consists of common equity tier 1 capital and our $118 million of trust preferred securities issued by the Trusts. The Basel III Rules include certain provisions that would require trust preferred securities to be phased out of qualifying tier 1 capital. Currently, our trust preferred securities are grandfathered under the Basel III Rules and will continue to be included as tier 1 capital. However, should we exceed $15 billion in total assets, the grandfather provisions applicable to its trust preferred securities would no longer apply and such trust preferred securities would no longer be included as tier 1 capital, but would continue to be included as total capital. The common equity tier 1 capital and the tier 1 capital are the same for our bank subsidiary.

76

Basel III Rules allow for insured depository institutions to make a one-time election not to include most elements of accumulated other comprehensive income in regulatory capital and instead effectively use the existing treatment under the general risk-based capital rules. We made this opt-out election for the first quarter of 2015 to avoid significant variations in the level of capital depending upon the impact of interest rate fluctuations on the fair value of our investment securities portfolio.

Total capital includes tier 1 capital and tier 2 capital. Tier 2 capital includes, among other things, the allowable portion of the ALLL and any trust preferred securities that are excluded from tier 1 capital.

The Basel III Rules also changed the risk-weights of assets in an effort to better reflect credit risk and other risk exposures.  These include a 150% risk weight (up from 100%) for certain high volatility commercial real estate acquisition, development and construction loans and the unsecured portion of non-residential mortgage loans that are 90 days past due or otherwise on nonaccrual status; a 20% (up from 0%) credit conversion factor for the unused portion of a commitment with an original maturity of one year or less that is not unconditionally cancellable; a 250% risk weight (up from 100%) for mortgage servicing rights and deferred tax assets that are not deducted from capital; and increased risk weights (from 0% to up to 600%) for equity exposures.

The common equity tier 1 capital, tier 1 capital and total capital ratios are calculated by dividing the respective capital amounts by risk-weighted assets. The leverage ratio is calculated by dividing tier 1 capital by adjusted quarterly average total assets.

The Basel III Rules limit capital distributions and certain discretionary bonus payments if the banking organization does not hold a “capital conservation buffer” consisting of 2.5% of common equity tier 1 capital, tier 1 capital and total capital to risk-weighted assets in addition to the amount necessary to meet minimum risk-based capital requirements.  The capital conservation buffer will be phased in beginning January 1, 2016, at 0.625% of risk-weighted assets, increasing each year by the same amount until fully implemented at 2.5% on January 1, 2019.  When fully phased in on January 1, 2019, the Basel III Rules will require us and our subsidiary bank to maintain (i) a minimum ratio of common equity tier 1 capital to risk-weighted assets of at least 4.5%, plus a 2.5% capital conservation buffer, which effectively results in a minimum ratio of 7.0% upon full implementation, (ii) a minimum ratio of tier 1 capital to risk-weighted assets of at least 6.0%, plus a 2.5% capital conservation buffer, which effectively results in a minimum ratio of 8.5% upon full implementation, (iii) a minimum ratio of total capital to risk-weighted assets of at least 8.0%, plus a 2.5% capital conservation buffer, which effectively results in a minimum ratio of 10.5% upon full implementation and (iv) a minimum leverage ratio of at least 4.0%.  Additionally, in order to be considered well-capitalized under the Basel III rules, we must maintain (i) a ratio common equity tier 1 capital to risk-weighted assets of at least 6.5%, (ii) a ratio of tier 1 capital to risk-weighted assets of at least 8.0%, (iii) a ratio of total capital to risk-weighted assets of at least 10.0%, and (iv) a leverage ratio of at least 5.0%.

Prior to January 1, 2015, federal and state regulatory agencies required us and our subsidiary bank to maintain minimum tier 1 and total capital to risk-weighted assets of 4.0% and 8.0%, respectively, and tier 1 capital to average quarterly assets (tier 1 leverage ratio) of at least 3.0%.  In order to be considered well capitalized under the rules in effect prior to January 1, 2015, we had to maintain tier 1 and total capital to risk-weighted assets of 6.0% and 10.0%, respectively, and a leverage ratio of 5.0%. Tier 1 capital consisted of common equity, retained earnings, certain types of preferred stock, qualifying minority interest and trust preferred securities, subject to limitations, and excluded goodwill and various intangible assets.  Total capital included tier 1 capital, any amounts of trust preferred securities excluded from tier 1 capital, and the lesser of the ALLL or 1.25% of risk-weighted assets.

Liquidity

General. Liquidity represents an institution’s ability to provide funds to satisfy demands from depositors, borrowers and other creditors by either converting assets into cash or accessing new or existing sources of incremental funds. Liquidity risk arises from the possibility we may be unable to satisfy current or future funding requirements and needs. The ALCO and Investments Committee (“ALCO”), which reports to our board of directors, has primary responsibility for oversight of our liquidity, funds management, asset/liability (interest rate risk) position and investment portfolio functions.

78

The objective of managing liquidity risk is to ensure the cash flow requirements resulting from depositor, borrower and other creditor demands are met, as well as our operating cash needs, and the cost of funding such requirements and needs is reasonable. We maintain an interest rate risk, liquidity and funds management policy and a contingency funding plan that, among other things, include policies and procedures for managing liquidity risk. Generally we rely on deposits, repayments of loans and leases, and cash flows from of our investment securities as our primary sources of funds. Our principal deposit sources include consumer, commercial and public funds customers in our markets. We have used these funds, together with wholesale deposit sources such as brokered deposits, along with FHLB advances, federal funds purchased and other sources of short-term borrowings, to make loans and leases, acquire investment securities and other assets and to fund continuing operations.

Deposit levels may be affected by a number of factors, including rates paid by competitors, general interest rate levels, returns available to customers on alternative investments, general economic and market conditions and other factors. Loan and lease repayments are a relatively stable source of funds but are subject to the borrowers’ and lessees’ ability to repay the loans and leases, which can be adversely affected by a number of factors including changes in general economic conditions, adverse trends or events affecting business industry groups or specific businesses, declines in real estate values or markets, business closings or lay-offs, inclement weather, natural disasters and other factors. Furthermore, loans and leases generally are not readily convertible to cash. Accordingly, we may be required from time to time to rely on secondary sources of liquidity to meet growth in loans and leases and deposit withdrawal demands or otherwise fund operations. Such secondary sources include wholesale deposit sources, FHLB advances, secured and unsecured federal funds lines of credit from correspondent banks, FRB borrowings and/or accessing the capital markets.

At December 31, 2015, we had substantial unused borrowing availability. This availability was primarily comprised of the following four options: (1) $2.56 billion of available blanket borrowing capacity with the FHLB, (2) $164 million of investment securities available to pledge for federal funds or other borrowings, (3) $170 million of available unsecured federal funds borrowing lines and (4) up to $143 million of available borrowing capacity from borrowing programs of the FRB.

We anticipate we will continue to rely primarily on deposits, repayments of loans and leases and cash flows from our investment securities to provide liquidity, as well as other funding sources as appropriate. Additionally, where necessary, the secondary funding sources described above will be used to augment our primary funding sources.

Sources and Uses of Funds. Operating activities provided net cash of $201 million in 2015, $97 million in 2014 and $59 million in 2013. Net cash provided by operating activities is comprised primarily of net income, adjusted for certain non-cash items and for changes in various operating assets and liabilities. The increase in net cash provided by operating activities for 2015 compared to 2014 and for 2014 compared to 2013 is primarily due to growth in our net income from $91.3 million in 2013 to $118.6 million in 2014 to $182.3 million in 2015.

Investing activities used net cash of $1.33 billion in 2015, $565 million in 2014 and $84 million in 2013. The increase in net cash used by investing activities in 2015 compared to 2014 and in 2014 compared to 2013 is primarily the result of growth in our non-purchased loans and leases, which used $2.58 billion in 2015, compared to $1.37 billion in 2014 and $545 million in 2013.  The use of cash as a result of growth in our non-purchased loan and lease portfolio was partially offset by cash provided by net activity in our investment securities portfolio, which provided $270 million in 2015 and $103 million in 2014, but used $54 million in 2013.  Additionally, we received net payments on purchased loans totaling $719 million in 2015, $468 million in 2014 and $292 million in 2013, and we received net cash in merger and acquisition transactions totaling $300 million in 2015, $122 million in 2014 and $57 million in 2013.

Financing activities provided net cash of $1.07 billion in 2015, $422 million in 2014 and $13 million in 2013. The increase in net cash provided by financing activities is primarily the result of growth of our deposits to fund our lending activities.  Our deposits provided $1.00 billion in 2015, $554 million in 2014 and $15 million in 2013. In addition, during 2015, we received proceeds of $110 million from the sale of 2,098,436 shares of our common stock.

Contractual Obligations. The following table presents, as of December 31, 2015, significant fixed and determinable contractual obligations to third parties by contractual date with no consideration given to earlier call or prepayment features. Other obligations consist primarily of contractual obligations for capital expenditures, software contracts and various other contractual obligations.

Growth and Expansion

De Novo Growth. In 2014, we opened loan production offices for our RESG in Houston, Texas and Los Angeles, California. We also opened retail banking offices in Bradenton, Florida, Cornelius, North Carolina and Hilton Head Island, South Carolina. In 2015, we opened two loan production offices, one in Little Rock, Arkansas and one in Greensboro, North Carolina, and we opened our fourth retail banking office in Houston, Texas. In 2016, we expect to open a loan production office for our RESG in San Francisco, California, and we expect to open retail banking offices in Siloam Springs, Arkansas, Fayetteville, Arkansas and Springdale, Arkansas.

We intend to continue our growth and de novo branching strategy in the future years through the opening of additional branches and loan production offices as our needs and resources permit. Opening new offices is subject to local banking market conditions, availability of suitable sites, hiring qualified personnel, obtaining regulatory and other approvals and many other conditions and contingencies that we cannot predict with certainty. We may increase or decrease our expected number of new office openings as a result of a variety of factors including our financial results, changes in economic or competitive conditions, strategic opportunities or other factors.

During 2015 we spent $16.8 million on capital expenditures for premises and equipment. Our capital expenditures for 2016 are expected to be in the range of $28 million to $42 million, including progress payments on construction projects expected to be

80

completed in 2016 and 2017, furniture and equipment costs and acquisition of sites for future development. Actual expenditures may vary significantly from those expected, depending on the number and cost of additional branch offices acquired or constructed and sites acquired for future development, progress or delays encountered on ongoing and new construction projects, delays in or inability to obtain required approvals, potential premises and equipment expenditures associated with acquisitions, if any, and other factors.

Acquisitions. We have shown substantial growth through a combination of organic growth and acquisitions. Since 2010, we have completed 13 acquisitions, including seven FDIC-assisted transactions, and in 2015, we announced two additional acquisitions, both of which are expected to close late in the first quarter of 2016 or in the second quarter of 2016.

In December 2012, we completed our acquisition of Genala Banc, Inc. (“Genala”) and The Citizens Bank, its wholly-owned bank subsidiary, for an aggregate of $13.4 million in cash and 847,232 shares of our common stock valued at $14.1 million. This was our first traditional acquisition since 2003. Genala operated one retail banking office in Geneva, Alabama.

In July 2013, we completed our acquisition of The First National Bank of Shelby (“First National Bank”) in Shelby, North Carolina for an aggregate of $8.4 million of cash and 2,514,770 shares of our common stock valued at $60.1 million.  The First National Bank acquisition expanded our service area in North Carolina by adding 14 retail banking offices in Shelby, North Carolina and surrounding communities.  In 2013 we closed one of the acquired offices in Shelby, North Carolina.  

In March 2014, we completed our acquisition of Bancshares, Inc. (“Bancshares”) of Houston, Texas and OMNIBANK, N.A., its wholly-owned bank subsidiary, for an aggregate of $21.5 million in cash.  The Bancshares acquisition expanded our service area in South Texas by adding three retail banking offices in Houston and one retail banking office each in Austin, Cedar Park, Lockhart and San Antonio.

In May 2014, we completed our acquisition of Summit Bancorp, Inc. (“Summit”) and Summit Bank, its wholly-owned bank subsidiary, for an aggregate of $42.5 million in cash and 5,765,846 shares of our common stock valued at $166.4 million.  The Summit acquisition expanded our service area in central, south and western Arkansas by adding 23 banking locations and one loan production office in nine Arkansas counties.  During 2014 we closed eight Arkansas banking offices in locations where we had excess branch capacity, six of which were acquired in the Summit acquisition, and we closed the loan production office acquired in the Summit acquisition.

On February 10, 2015, we completed our acquisition of Intervest and its wholly-owned bank subsidiary Intervest National Bank, headquartered in New York, New York, whereby we acquired all of the outstanding common stock of Intervest in exchange for 6,637,243 shares of our common stock (plus cash in lieu of fractional shares) in a transaction valued at approximately $238.5 million.  The Intervest acquisition added seven retail banking offices including one in New York City, five in Clearwater, Florida and one in Pasadena, Florida.  During the third quarter of 2015, we closed one of the acquired offices in Clearwater, Florida. During the fourth quarter of 2015, we eliminated the New York lending operations acquired in the Intervest acquisition, which we refer to as Stabilized Properties Group (or SPG), and consolidated the remaining servicing team of the SPG into our Real Estate Properties Group.

On August 5, 2015, we completed our acquisition of Bank of the Carolinas Corporation (“BCAR”) and its wholly-owned bank subsidiary Bank of the Carolinas for an aggregate of 1,447,620 shares of our common stock (plus cash in lieu of fractional shares) in a transaction valued at approximately $65.4 million.  The BCAR acquisition expanded our operations in North Carolina by adding eight retail banking offices, including one office each in Advance, Asheboro, Concord, Harrisburg, Landis, Lexington, Mocksville and Winston-Salem.

On October 19, 2015, we entered into a definitive agreement and plan of merger (the “C&S Agreement”) with Community and Southern Holdings, Inc. (“C&S”) and its wholly-owned bank subsidiary Community & Southern Bank, whereby we expect to acquire all of the outstanding common stock and equity awards of C&S in a transaction valued at approximately $799.6 million.  C&S is headquartered in Atlanta, Georgia and operates 47 retail banking offices throughout Georgia and one retail banking office in Jacksonville, Florida.  At December 31, 2015, C&S had approximately $4.2 billion in total assets, approximately $3.1 billion in total loans, approximately $3.7 billion in total deposits and approximately $460 million in stockholders’ equity. The closing of the C&S transaction, which is expected to occur late in the first quarter or in the second quarter of 2016, is subject to certain closing conditions, including receipt of customary regulatory approvals.  

On November 9, 2015, we entered into a definitive agreement and plan of merger (the “C1 Agreement”) with C1 Financial, Inc. (“C1”) and its wholly-owned bank subsidiary C1 Bank, whereby we expect to acquire all of the outstanding common stock of C1 in a transaction valued at approximately $402.5 million. C1 is headquartered in St. Petersburg, Florida and operates 32 retail banking offices on the west coast of Florida and in Miami-Dade and Orange Counties.  At December 31, 2015, C1 had approximately $1.7 billion in total assets, approximately $1.4 billion in total loans, approximately $1.3 billion in total deposits and approximately $201 million in stockholders’ equity. The closing of the C1 transaction, which is expected to occur late in the first quarter or in the second

81

quarter of 2016, is subject to certain closing conditions, including receipt of customary regulatory approvals and the approval of C1 shareholders.

Future Growth Strategy. We expect to continue growing through both our de novo branching strategy and traditional acquisitions. With respect to de novo branching strategy, future de novo branches are expected to be focused in states where we currently have banking offices and in larger markets and metropolitan areas across the United States where we currently do not have offices and believe we can generate significant growth from one or two strategically located offices in each such market. Future RESG loan production offices are expected to be focused in strategically important markets (most likely San Francisco in late February and offices in Seattle, Washington, D.C., Boston and Chicago at later dates). With respect to traditional acquisitions, we are seeking acquisitions that are either immediately accretive to book value, tangible book value and diluted earnings per share, or strategic in location, or both.

Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The disclosures set forth in this item are qualified by Item 1A. Risk Factors and the section captioned “Forward-Looking Information” and other cautionary statements set forth elsewhere in this report.

Interest Rate Risk

Interest rate risk results from timing differences in the repricing of assets and liabilities or from changes in relationships between interest rate indices. Interest rate risk management is the responsibility of our ALCO.

We regularly review our exposure to changes in interest rates. Among the factors considered are changes in the mix of interest earning assets and interest bearing liabilities, interest rate spreads and repricing periods. Typically, the ALCO reviews on at least a quarterly basis our relative ratio of rate sensitive assets (“RSA”) to rate sensitive liabilities (“RSL”) and the related cumulative gap for different time periods. However, the primary tool used by the ALCO to analyze our interest rate risk and interest rate sensitivity is an earnings simulation model.

This earnings simulation modeling process projects a baseline net interest income (assuming no changes in interest rate levels) and estimates changes to that baseline net interest income resulting from changes in interest rate levels. We rely primarily on the results of this model in evaluating our interest rate risk. This model incorporates a number of factors including: (1) the expected exercise of call features on various assets and liabilities, (2) the expected rates at which various RSA and RSL will reprice, (3) the expected growth in various interest earning assets and interest bearing liabilities and the expected interest rates on such new assets and liabilities, (4) the expected relative movements in different interest rate indices which are used as the basis for pricing or repricing various assets and liabilities, (5) existing and expected contractual ceiling and floor rates on various assets and liabilities, (6) expected changes in administered rates on interest bearing transaction, savings, money market and time deposit accounts and the expected impact of competition on the pricing or repricing of such accounts and (7) other relevant factors. Inclusion of these factors in the model is intended to more accurately project our expected changes in net interest income resulting from interest rate changes. We model our change in net interest income assuming interest rates go up 100 bps, up 200 bps, up 300 bps, up 400 bps, up 500 bps, down 100 bps, down 200 bps, down 300 bps, down 400 bps and down 500 bps. Based on current conditions, we believe that modeling a change in net interest income assuming rates go down 100 bps, down 200 bps, down 300 bps, down 400 bps and down 500 bps is not meaningful. For purposes of this model, we have assumed that the change in interest rates phases in over a 12-month period. While we believe this model provides a reasonably accurate projection of our interest rate risk, the model includes a number of assumptions and predictions which may or may not be correct and may impact the model results. These assumptions and predictions include inputs to compute baseline net interest income, growth rates, expected changes in administered rates on interest bearing deposit accounts, competition and a variety of other factors that are difficult to accurately predict. Accordingly, there can be no assurance the earnings simulation model will accurately reflect future results.

82

The following table presents the earnings simulation model’s projected impact of a change in interest rates on the projected baseline net interest income for the 12-month period commencing January 1, 2016. This change in interest rates assumes parallel shifts in the yield curve and does not take into account changes in the slope of the yield curve.

Earnings Simulation Model Results

Change in Interest Rates (in bps)	% Change in Projected Baseline Net Interest Income
+500		16.3%
+400		12.9
+300		9.6
+200		6.2
+100		3.0
-100	Not meaningful
-200	Not meaningful
-300	Not meaningful
-400	Not meaningful
-500	Not meaningful

In the event of a shift in interest rates, we may take certain actions intended to mitigate the negative impact to net interest income or to maximize the positive impact to net interest income. These actions may include, but are not limited to, restructuring of interest earning assets and interest bearing liabilities, seeking alternative funding sources or investment opportunities and modifying the pricing or terms of loans, leases and deposits.

Impact of Inflation and Changing Prices

The Consolidated Financial Statements and related notes presented elsewhere in this report have been prepared in accordance with GAAP. This requires the measurement of financial position and operating results in terms of historical dollars without considering the changes in the relative purchasing power of money over time due to inflation. Unlike most industrial companies, the vast majority of our assets and liabilities are monetary in nature. As a result, interest rates have a greater impact on our performance than do the effects of general levels of inflation. Interest rates do not necessarily move in the same direction or to the same extent as the prices of goods and services.

Item 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA 

Report of Independent Registered Public Accounting Firm

Board of Directors and Stockholders

Bank of the Ozarks, Inc.

We have audited the accompanying consolidated balance sheets of Bank of the Ozarks, Inc. (the “Company”) as of December 31, 2015 and 2014 and the related consolidated statements of income, comprehensive income, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2015. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits 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 the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Bank of the Ozarks, Inc. at December 31, 2015 and 2014 and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2015, in conformity with accounting principles generally accepted in the United States of America.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Bank of the Ozarks, Inc.’s internal control over financial reporting as of December 31, 2015, based on the criteria established in the Internal Control-Integrated Framework issued in 2013 by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 19, 2016, expressed an unqualified opinion thereon.

Bank of the Ozarks, Inc.

Notes to Consolidated Financial Statements

December 31, 2015, 2014 and 2013

1. Summary of Significant Accounting Policies

Organization – Bank of the Ozarks, Inc. (the “Company”) is a bank holding company headquartered in Little Rock, Arkansas, which operates under the rules and regulations of the Board of Governors of the Federal Reserve System. The Company owns a wholly-owned state chartered bank subsidiary – Bank of the Ozarks (the “Bank”). As of December 31, 2015, the Company owns eight 100%-owned finance subsidiary business trusts including Ozark Capital Statutory Trust II (“Ozark II”), Ozark Capital Statutory Trust III (“Ozark III”), Ozark Capital Statutory Trust IV (“Ozark IV”), Ozark Capital Statutory Trust V (“Ozark V”) (collectively, the “Ozark Trusts”), and as a result of the Company’s acquisition of Intervest Bancshares Corporation (“Intervest”), Intervest Statutory Trust II (“Intervest II”), Intervest Statutory Trust III (“Intervest III”), Intervest Statutory Trust IV (“Intervest IV”) and Intervest Statutory Trust V (“Intervest V”), (collectively, the “Intervest Trusts”; and together with Ozark Trusts, the “Trusts”). Each of the Trusts was formed in connection with the issuance of certain subordinated debentures and related trust preferred securities.  At December 31, 2015, the Company also owns, indirectly through the Bank, a subsidiary engaged in the development of real estate, a subsidiary that owns private aircraft and various other entities that hold foreclosed assets or tax credits or engage in other activities. The Company and the Bank are subject to the regulation of certain federal and state agencies and undergo periodic examinations by those regulatory authorities. At December 31, 2015, the Company, through the Bank, conducted operations through 174 offices, including 81 offices in Arkansas, 28 in Georgia, 25 in North Carolina, 22 in Texas, ten in Florida, three in Alabama, two offices each in South Carolina and New York and one office in California.

Basis of presentation, use of estimates and principles of consolidation – The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“GAAP”) requires management to make estimates, assumptions and judgments that affect the amounts reported in the Consolidated Financial Statements and accompanying notes. Actual results could differ from those estimates.

The Consolidated Financial Statements include the accounts of the Company, the Bank, the real estate subsidiary and the aircraft subsidiary. In addition, subsidiaries in which the Company has majority voting interest (principally defined as owning a voting or economic interest greater than 50%) or where the Company exercises control over the operating and financial policies of the subsidiary through an operating agreement or other means are consolidated. Investments in companies in which the Company has significant influence over voting and financing decisions (principally defined as owning a voting or economic interest of 20% to 50%) and investments in limited partnerships and limited liability companies where the Company does not exercise control over the operating and financial policies are generally accounted for by the equity method of accounting. Investments in companies in which the Company has limited or no influence over voting and financing decisions (principally defined as owning a voting or economic interest less than 20%) and investments in limited partnerships and limited liability companies in which the Company’s interest is so minor such that it has virtually no influence over operating and financial policies are generally accounted for by the cost method of accounting. Significant intercompany transactions and amounts have been eliminated in consolidation.

The voting interest approach is not applicable for entities that are not controlled through voting interests or in which the equity investors do not bear the residual economic risk. In such instances, management makes a determination, based on its review of applicable GAAP, on when the assets, liabilities and activities of a variable interest entity (“VIE”) should be included in the Company’s Consolidated Financial Statements. GAAP requires a VIE to be consolidated by a company if that company is considered the primary beneficiary of the VIE’s activities. The Company has determined that the 100%-owned finance subsidiary Trusts are VIEs, but that the Company is not the primary beneficiary of the Trusts. Accordingly, the Company does not consolidate the activities of the Trusts into its financial statements, but instead reports its ownership interests in the Trusts as other assets and reports the subordinated debentures issued to the Trusts as a liability in the consolidated balance sheets. The distributions on the subordinated debentures are reported as interest expense in the accompanying consolidated statements of income.

Cash and cash equivalents – For cash flow purposes, cash and cash equivalents include cash on hand, amounts due from banks and interest earning deposits with banks.

Investment securities – Management determines the appropriate classification of investment securities at the time of purchase and reevaluates such designation as of each balance sheet date. At December 31, 2015 and 2014, the Company has classified all of its investment securities as available for sale (“AFS”).

Investment securities AFS are reported at estimated fair value, with the unrealized gains and losses determined on a specific identification basis. Such unrealized gains and losses, net of tax, are reported as a separate component of stockholders’ equity and included in other comprehensive income (loss). The Company utilizes independent third parties as its principal pricing sources for

93

determining fair value of investment securities which are measured on a recurring basis. As a result, the Company receives estimates of fair values from at least two independent pricing sources for the majority of its individual securities within its investment portfolio. For investment securities traded in an active market, fair values are based on quoted market prices if available. If quoted market prices are not available, fair values are based on quoted market prices of comparable securities, broker quotes or comprehensive interest rate tables, pricing matrices or a combination thereof. For investment securities traded in a market that is not active, fair value is determined using unobservable inputs. Additionally, the valuation of investment securities acquired may include certain unobservable inputs. All fair value estimates received by the Company for its investment securities are reviewed and approved on a quarterly basis by the Company’s Investment Portfolio Manager and its Chief Financial Officer.

At December 31, 2015 and 2014, the Company owned stock in the Federal Home Loan Bank of Dallas (“FHLB”) and First National Banker’s Bankshares, Inc. (“FNBB”), which do not have readily determinable fair values and are carried at cost.

Declines in the fair value of investment securities below their amortized cost are reviewed at least quarterly by the Company for other-than-temporary impairment. Factors considered during such review include, among other things, the length of time and extent that fair value has been less than cost and the financial condition and near term prospects of the issuer. The Company also assesses whether it has the intent to sell the investment security or more likely than not would be required to sell the investment security before any anticipated recovery in fair value. If either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost and fair value is recognized as impairment through the income statement. For securities that do not meet the aforementioned criteria, the amount of impairment is split into (i) other-than-temporary impairment related to credit loss, which must be recognized in the income statement, and (ii) other-than-temporary impairment related to other factors, which is recognized in other comprehensive income (loss). The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis.

The fair values of the Company’s investment securities traded in both active and inactive markets can be volatile and may be influenced by a number of factors including market interest rates, prepayment speeds, discount rates, credit quality of the issuer, general market conditions including market liquidity conditions and other factors. Factors and conditions are constantly changing and fair values could be subject to material variations that may significantly impact the Company’s financial condition, results of operations and liquidity.

Interest and dividends on investment securities, including the amortization of premiums and accretion of discounts through maturity, or in the case of mortgage-backed securities, over the estimated life of the security, are included in interest income. Realized gains or losses on the sale of investment securities are recognized on the specific identification method at the time of sale and are included in non-interest income. Purchases and sales of investment securities are recorded on a trade-date basis.

Non-purchased loans and leases – Non-purchased loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at their outstanding principal balance adjusted for any charge-offs and deferred fees or costs. Interest on non-purchased loans is recognized on an accrual basis and is calculated using the simple interest method on daily balances of the principal amount outstanding. Loan origination fees and costs are generally deferred and recognized over the life of the loan as an adjustment to yield on the related loan.

Leases, all of which are non-purchased, are classified as either direct financing leases or operating leases, based on the terms of the agreement. Direct financing leases are reported as the sum of (i) total future lease payments to be received, net of unearned income, and (ii) estimated residual value of the leased property. Operating leases are recorded at the cost of the leased property, net of accumulated depreciation. Income on direct financing leases is included in interest income and is recognized on a basis that achieves a constant periodic rate of return on the outstanding investment. Income on operating leases is recognized as non-interest income on a straight-line basis over the lease term.

In the ordinary course of business, the Company has entered into off-balance sheet financial instruments consisting of commitments to extend credit and letters of credit. Such financial instruments are recorded in the financial statements when they are funded. Related fees are generally recognized when collected.

Mortgage loans held for sale are included in the Company’s non-purchased loans and leases and totaled $10.4 million and $10.9 million at December 31, 2015 and 2014, respectively. Mortgage loans held for sale are carried at the lower of cost or fair value. Gains and losses from the sales of mortgage loans are the difference between the selling price of the loan and its carrying value, net of discounts and points, and are recognized as mortgage lending income when the loan is sold to investors and servicing rights are released.

As part of its standard mortgage lending practice, the Company issues a written put option, in the form of an interest rate lock commitment (“IRLC”), such that the interest rate on the mortgage loan is established prior to funding. In addition to the IRLC, the

94

Company enters into a forward sale commitment (“FSC”) for the sale of its mortgage loan originations to reduce its market risk and interest rate risk on such originations in process. The IRLC on mortgage loans held for sale and the FSC have been determined to be derivatives as defined by GAAP. Accordingly, the fair values of derivative assets and liabilities for the Company’s IRLC and FSC are based primarily on the fluctuation of interest rates between the date on which the particular IRLC and FSC were entered into and year-end. At December 31, 2015 and 2014, respectively, the Company’s IRLC and FSC derivative assets and corresponding derivative liabilities were not material. The notional amounts of loan commitments under both the IRLC and FSC were $15.7 million and $17.2 million at December 31, 2015 and 2014, respectively.

Purchased loans – Purchased loans are initially recorded at fair value on the date of purchase. Purchased loans that contain evidence of credit deterioration on the date of purchase are carried at the net present value of expected future proceeds. All other purchased loans are recorded at their initial fair value, adjusted for subsequent advances, pay downs, amortization or accretion of any premium or discount on purchase, charge-offs and any other adjustment to carrying value.

As provided for under GAAP, management has up to 12 months following the date of the acquisition to finalize the fair values of acquired assets and assumed liabilities. Once management has finalized the fair values of acquired assets and assumed liabilities within this 12-month period, management considers such values to be the day 1 fair values (“Day 1 Fair Values”).

At the time of acquisition of purchased loans, management individually evaluates substantially all loans acquired in the transaction. For those purchased loans without evidence of credit deterioration, management evaluates each reviewed loan using an internal grading system with a grade assigned to each loan at the date of acquisition. To the extent that any purchased loan is not specifically reviewed, such loan is assumed to have characteristics similar to the characteristics of the acquired portfolio of purchased loans. The grade for each purchased loan without evidence of credit deterioration is reviewed subsequent to the date of acquisition any time a loan is renewed or extended or at any time information becomes available to the Company that provides material insight regarding the loan’s performance, the status of the borrower or the quality or value of the underlying collateral. To the extent that current information indicates it is probable that the Company will collect all amounts according to the contractual terms thereof, such loan is not considered impaired and is not individually considered in the determination of the required allowance for loan and lease losses (“ALLL”). To the extent that current information indicates it is probable that the Company will not be able to collect all amounts according to the contractual terms thereof, such loan is considered impaired and is considered in the determination of the required level of ALLL.

In determining the Day 1 Fair Values of purchased loans without evidence of credit deterioration at the date of acquisition, management includes (i) no carry over of any previously recorded ALLL and (ii) an adjustment of the unpaid principal balance to reflect an appropriate market rate of interest, given the risk profile and grade assigned to each loan. This adjustment is accreted into earnings as a yield adjustment, using the effective yield method, over the remaining life of each loan.

Purchased loans that contain evidence of credit deterioration on the date of purchase are individually evaluated by management to determine the estimated fair value of each loan. This evaluation includes no carryover of any previously recorded ALLL. In determining the estimated fair value of purchased loans with evidence of credit deterioration, management considers a number of factors including, among other things, the remaining life of the acquired loans, estimated prepayments, estimated loss ratios, estimated value of the underlying collateral, estimated holding periods, and net present value of cash flows expected to be received.

In determining the Day 1 Fair Values of purchased loans with evidence of credit deterioration at the date of acquisition, management calculates a non-accretable difference (the credit component of the purchased loans) and an accretable difference (the yield component of the purchased loans). The non-accretable difference is the difference between the contractually required payments and the cash flows expected to be collected in accordance with management’s determination of the Day 1 Fair Values. Subsequent increases in expected cash flows will result in an adjustment to accretable yield, which will have a positive impact on interest income. Subsequent decreases in expected cash flows will generally result in a provision for loan and lease losses. Subsequent increases in expected cash flows following any previous decrease will result in a reversal of the provision for loan and lease losses to the extent of prior charges and then an adjustment to accretable yield.

The accretable difference on purchased loans with evidence of credit deterioration at the date of acquisition is the difference between the expected cash flows and the net present value of such expected cash flows. Such difference is accreted into earnings using the effective yield method over the term of the loans. In determining the net present value of the expected cash flows for purposes of establishing the Day 1 Fair Values, the Company used discount rates ranging from 6.0% to 9.5% per annum depending on the risk characteristics of each individual loan.

Management separately monitors purchased loans with evidence of credit deterioration on the date of purchase and periodically reviews such loans contained within this portfolio against the factors and assumptions used in determining the Day 1 Fair Values. A loan is reviewed (i) any time it is renewed or extended, (ii) at any other time additional information becomes available to the Company

95

that provides material additional insight regarding the loan’s performance, the status of the borrower, or the quality or value of the underlying collateral, or (iii) in conjunction with the annual review of projected cash flows of each acquired portfolio. Management separately reviews the performance of the portfolio of purchased loans with evidence of credit deterioration at the date of acquisition on an annual basis, or more frequently to the extent that material information becomes available regarding the performance of an individual loan, to make determinations of the constituent loans’ performance and to consider whether there has been any significant change in performance since management’s initial expectations established in conjunction with the determination of the Day 1 Fair Values or since management’s most recent review of such portfolio’s performance. To the extent that a loan is performing in accordance with or exceeding management’s performance expectation established in conjunction with the determination of the Day 1 Fair Values, such loan is rated FV66, is not included in any of the credit quality ratios, is not considered to be a nonaccrual, nonperforming or impaired loan, and is not considered in the determination of the required ALLL. For any loan that is exceeding management’s performance expectation established in conjunction with the determination of Day 1 Fair Values, the accretable yield on such loan is adjusted to reflect such increased performance. To the extent that a loan’s performance has deteriorated from management’s expectation established in conjunction with the determination of the Day 1 Fair Values, such loan is rated FV88, is included in certain of the Company’s credit quality metrics, is considered an impaired loan, and is considered in the determination of the required level of ALLL; however, in accordance with GAAP, the Company continues to accrete into earnings income on such loans. Any improvement in the expected performance of such loan would result in a reversal of the provision for loan and lease losses to the extent of prior charges and then an adjustment to accretable yield.

Allowance for loan and lease losses – The ALLL is established through a provision for such losses charged against income. All or portions of loans or leases deemed to be uncollectible are charged against the ALLL when management believes that collectability of all or some portion of outstanding principal is unlikely. Subsequent recoveries, if any, of loans or leases previously charged off are credited to the ALLL.

The ALLL is maintained at a level management believes will be adequate to absorb probable incurred losses in the loan and lease portfolio. Provision to and the adequacy of the ALLL are based on evaluations of the loan and lease portfolio utilizing objective and subjective criteria. The objective criteria primarily include an internal grading system and specific allowances. In addition to the objective criteria, the Company subjectively assesses the adequacy of the ALLL and the need for additions thereto, with consideration given to the nature and mix of the portfolio, including concentrations of credit; general economic and business conditions, including national, regional and local business and economic conditions that may affect borrowers’ or lessees’ ability to pay; expectations regarding the current business cycle; trends that could affect collateral values and other relevant factors. The Company also utilizes a peer group analysis and a historical analysis to validate the overall adequacy of its ALLL. Changes in any of these criteria or the availability of new information could require adjustment of the ALLL in future periods. While a specific allowance has been calculated for impaired loans and leases and for loans and leases where the Company has otherwise determined a specific reserve is appropriate, no portion of the Company’s ALLL is restricted to any individual loan or lease or group of loans or leases, and the entire ALLL is available to absorb losses from any and all loans and leases.

The Company’s internal grading system assigns grades to all non-purchased loans and leases, except residential 1-4 family loans, consumer loans and certain other loans, with each grade being assigned an allowance allocation percentage. The grade for each graded individual loan or lease is determined by the account officer and other approving officers at the time the loan or lease is made and changed from time to time to reflect an ongoing assessment of loan or lease risk. Grades are reviewed on specific loans and leases from time to time by senior management and as part of the Company’s internal loan review process. The risk elements considered by management in its determination of the appropriate grade for individual loans and leases include the following, among others: (1) for non-farm/non-residential, multifamily residential, and agricultural real estate loans, the debt service coverage ratio (income from the property in excess of operating expenses compared to loan repayment requirements), operating results of the owner in the case of owner-occupied properties, the loan-to-value ratio, the age, condition, value, nature and marketability of the collateral and the specific risks and volatility of income, property value and operating results typical of properties of that type; (2) for construction and land development loans, the perceived feasibility of the project including the ability to sell developed lots or improvements constructed for resale or ability to lease property constructed for lease, the quality and nature of contracts for presale or preleasing, if any, experience and ability of the developer and loan-to-cost and loan-to-value ratios; (3) for commercial and industrial loans and leases, the operating results of the commercial, industrial or professional enterprise, the borrower’s or lessee’s business, professional and financial ability and expertise, the specific risks and volatility of income and operating results typical for businesses in the applicable industry, the age, condition, value, nature and marketability of collateral and, for certain loans, the marketability of such loans in any secondary market; and (4) for non-real estate agricultural loans and leases, the operating results, experience and ability of the borrower or lessee, historical and expected market conditions and the age, condition, value, nature and marketability of collateral. In addition, for each category the Company considers secondary sources of income and the financial strength of the borrower or lessee and any guarantors.

Residential 1-4 family, consumer loans and certain other loans are assigned an allowance allocation percentage based on past due status.

96

Allowance allocation percentages for the various risk grades and past due categories for residential 1-4 family, consumer loans and certain other loans are determined by management and are adjusted periodically. In determining these allowance allocation percentages, management considers, among other factors, historical loss percentages over various time periods and a variety of subjective criteria.

For purchased loans, management segregates this portfolio into loans that contain evidence of credit deterioration on the date of acquisition and loans that do not contain evidence of credit deterioration on the date of acquisition. Purchased loans with evidence of credit deterioration are regularly monitored and are periodically reviewed by management. To the extent that a loan’s performance has deteriorated from management’s expectation established in conjunction with the determination of the Day 1 Fair Values, such loan is considered in the determination of the required level of ALLL. To the extent that a revised loss estimate exceeds the loss estimate established in the determination of Day 1 Fair Values, such determination will result in an allowance allocation or a partial or full charge-off.

All other purchased loans are graded by management at the time of purchase. The grade on these purchased loans is reviewed regularly as part of the ongoing assessment of such loans. To the extent that current information indicates it is probable that the Company will not be able to collect all amounts according to the contractual terms thereof, such loan is considered in the determination of the required level of ALLL and may result in an allowance allocation or a partial or full charge-off.

At December 31, 2015, the Company established an ALLL totaling $1.2 million for its purchased loan portfolio.  Such ALLL was based on the Company’s historical charge-off analysis of its purchased loan portfolio and reflects management’s estimate of probable incurred losses in the purchased loan portfolio that had not previously been charged off.  At December 31, 2014, the Company had no ALLL for its purchased loan portfolio as the Company had determined that all losses had been charged off on purchased loans where management had determined it was probable that the Company would be unable to collect all amounts according to the contractual terms thereof (for purchased loans without evidence of credit deterioration at date of acquisition) or whose performance had deteriorated from management’s expectations established in conjunction with the determination of the Day 1 Fair Values (for purchased loans with evidence of credit deterioration at date of acquisition).

The accrual of interest on non-purchased loans and leases and purchased loans without evidence of credit deterioration at the date of acquisition is discontinued when, in management’s opinion, the borrower or lessee may be unable to meet payments as they become due. The Company generally places a loan or lease, excluding purchased loans with evidence of credit deterioration on the date of acquisition, on nonaccrual status when such loan or lease is (i) deemed impaired or (ii) 90 days or more past due, or earlier when doubt exists as to the ultimate collection of payments. The Company may continue to accrue interest on certain loans or leases contractually past due 90 days or more if such loans or leases are both well secured and in the process of collection. At the time a loan or lease is placed on nonaccrual status, interest previously accrued but uncollected is reversed and charged against interest income. Nonaccrual loans and leases are generally returned to accrual status when payments are less than 90 days past due and the Company reasonably expects to collect all payments. If a loan or lease is determined to be uncollectible, the portion of the principal determined to be uncollectible will be charged against the ALLL. Loans for which the terms have been modified and for which (i) the borrower is experiencing financial difficulties and (ii) a concession has been granted to the borrower by the Company are considered troubled debt restructurings (“TDRs”) and are included in impaired loans and leases. Income on nonaccrual loans or leases, including impaired loans and leases but excluding certain TDRs which continue to accrue interest, is recognized on a cash basis when and if actually collected.

All loans and leases deemed to be impaired are evaluated individually. The Company considers a loan or lease, excluding purchased loans with evidence of credit deterioration at the date of acquisition, to be impaired when based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms thereof. The Company considers a purchased loan with evidence of credit deterioration at the date of acquisition to be impaired once a decrease in expected cash flows or other deterioration in the loan’s expected performance, subsequent to the determination of the Day 1 Fair Values, results in an allowance allocation, a partial or full charge-off or in a provision for loan and lease losses. Most of the Company’s nonaccrual loans and leases, excluding purchased loans with evidence of credit deterioration at the date of acquisition, and all TDRs are considered impaired. The majority of the Company’s impaired loans and leases are dependent upon collateral for repayment. For such loans and leases, impairment is measured by comparing collateral value, net of holding and selling costs, to the current investment in the loan or lease. For all other impaired loans and leases, the Company compares estimated discounted cash flows to the current investment in the loan or lease. To the extent that the Company’s current investment in a particular loan or lease exceeds its estimated net collateral value or its estimated discounted cash flows, the impaired amount is specifically considered in the determination of the ALLL or is charged off as a reduction of the ALLL. The Company’s practice is to charge off any estimated loss as soon as management is able to identify and reasonably quantify such potential loss. Accordingly, only a small portion of the Company’s ALLL is needed for potential losses on nonperforming loans.

The Company also maintains an allowance for certain non-purchased loans and leases not considered impaired where (i) the customer is continuing to make regular payments, although payments may be past due, (ii) there is a reasonable basis to believe the

97

customer may continue to make regular payments, although there is also an elevated risk that the customer may default, and (iii) the collateral or other repayment sources are likely to be insufficient to recover the current investment in the loan or lease if a default occurs. The Company evaluates such loans and leases to determine if an allowance is needed for these loans and leases. For the purpose of calculating the amount of such allowance, management assumes that (i) no further regular payments occur and (ii) all sums recovered will come from liquidation of collateral and collection efforts from other payment sources. To the extent that the Company’s current investment in a particular loan or lease evaluated for the need for such allowance exceeds its net collateral value, such excess is considered allocated allowance for purposes of the determination of the ALLL.

The Company also includes specific ALLL allocations for qualitative factors including, (i) general economic and business conditions, (ii) trends that could affect collateral values and (iii) expectations regarding the current business cycle. The Company may also consider other qualitative factors in future periods for additional ALLL allocations.

Changes in the criteria used in this evaluation or the availability of new information could cause the ALLL to be increased or decreased in future periods. In addition, bank regulatory agencies, as part of their examination process, may require adjustments to the ALLL based on their judgment and estimates.

Premises and equipment – Premises and equipment are reported at cost less accumulated depreciation and amortization. Depreciation and amortization are computed on a straight-line basis over the estimated useful lives of the related assets. Depreciable lives for the major classes of assets are generally 20 to 45 years for buildings and 3 to 25 years for furniture, fixtures, equipment and certain building improvements. Leasehold improvements are amortized over the shorter of the asset’s estimated useful life or the term of the lease. Accelerated depreciation methods are used for income tax purposes. Maintenance and repair charges are expensed as incurred.

Foreclosed assets – Repossessed personal properties and real estate acquired through or in lieu of foreclosure, excluding purchased foreclosed assets, are initially recorded at the lesser of current principal investment or fair value less estimated cost to sell (generally 8% to 10%) at the date of repossession or foreclosure. Purchased foreclosed assets are initially recorded at Day 1 Fair Values. In estimating such Day 1 Fair Values, management considered a number of factors including, among others, appraised value, estimated selling price, estimated holding periods and net present value (calculated using discount rates ranging from 8.0% to 9.5% per annum) of cash flows expected to be received.

Valuations of all foreclosed assets are periodically reviewed by management with the carrying value of such assets adjusted through non-interest expense to the then estimated fair value, generally based on third party appraisals, broker price opinions or other valuations of the property, net of estimated selling costs, if lower, until disposition. Gains and losses from the sale of such repossessions and real estate acquired through or in lieu of foreclosure are recorded in non-interest income, and expenses to maintain the properties are included in non-interest expense.

Income taxes – The Company utilizes the asset and liability method in accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based upon the difference between the values of the assets and liabilities as reflected in the financial statements and their related tax basis using enacted tax rates in effect for the year or years in which the differences are expected to be recovered or settled. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes.

As a result of recording, at fair value, acquired assets and assumed liabilities pursuant to business combinations, differences in amounts reported for financial statement purposes and their related basis for federal and state income tax purposes are created. Such differences are recorded as deferred tax assets and liabilities using enacted tax rates in effect for the year or years in which the differences are expected to be recovered or settled. Business combination transactions may result in the acquisition of net operating loss carryforwards and other assets with built-in losses, the realization of which are subject to limitations pursuant to section 382 (“section 382 limitation”) of the Internal Revenue Code (“IRC”). In determining the section 382 limitation associated with a business combination, management must make a number of estimates and assumptions regarding the ability to utilize acquired net operating loss carryforwards and the expected timing of future recoveries or settlements of acquired assets with built-in losses. To the extent that information available as of the date of acquisition results in a determination by management that some portion of acquired net operating loss carryforwards cannot be utilized or assets with built-in losses are expected to be settled or recovered in future periods in which the ability to realize the benefits will be subject to section 382 limitation, a deferred tax asset valuation allowance is established for the estimated amount of the deferred tax assets subject to the section 382 limitation. To the extent that information becomes available, during the first 12 months following the consummation of a business combination transaction, that results in changes in management’s initial estimates and assumptions regarding the expected utilization of acquired net operating loss carryforwards or the expected settlement or recovery of acquired assets with built-in losses subject to section 382 limitation, an increase or decrease of the deferred tax asset valuation allowance will be recorded as an adjustment to bargain purchase gain or goodwill. To the extent that such information becomes available 12 months or more after the consummation of a business combination transaction, or additional

98

information becomes available during the first 12 months as a result of changes in circumstances since the date of the consummation of a business combination transaction, an increase or decrease of the deferred tax asset valuation allowance will be recorded as an adjustment to deferred income tax expense (benefit).

The Company recognizes a tax position as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that has a greater than 50% likelihood of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded.

The Company files consolidated tax returns. The Bank and the other consolidated entities provide for income taxes on a separate return basis and remit to the Company amounts determined to be currently payable. The Company recognizes interest related to income tax matters as interest income or expense, and penalties related to income tax matters are recognized as non-interest expense. The Company is no longer subject to income tax examinations by U.S. federal tax authorities for years prior to 2012.

Bank owned life insurance (“BOLI”) – BOLI consists of life insurance purchased by the Company on (i) a qualifying group of officers with the Company designated as owner and beneficiary of the policies and (ii) one of the Company’s executive officers with the Company designated as owner and both the Company and the executive officer designated as beneficiaries of the policies. The earnings on BOLI policies help to offset a portion of employee benefit costs or to offset a portion of the costs of a supplemental executive retirement plan for one of the Company’s executive officers. BOLI is carried at the policies’ realizable cash surrender values with changes in cash surrender values and death benefits received in excess of cash surrender values reported in non-interest income.

Intangible assets – Intangible assets consist of goodwill, bank charter costs and core deposit intangibles. Goodwill represents the excess purchase price over the fair value of net assets acquired in business acquisitions. The Company had goodwill of $125.4 million and $78.7 million at December 31, 2015 and 2014, respectively. The Company performed its annual impairment test of goodwill as of September 30, 2015. This test indicated no impairment of the Company’s goodwill.

Bank charter costs represent costs paid to acquire a Texas bank charter and are being amortized over 20 years. Bank charter costs totaled $239,000 at both December 31, 2015 and 2014, less accumulated amortization of $144,000 and $132,000 at December 31, 2015 and 2014, respectively.

Core deposit intangibles represent premiums paid for deposits acquired via acquisition and are being amortized over three to seven years. Core deposit intangibles totaled $41.5 million and $36.5 million at December 31, 2015 and 2014, respectively, less accumulated amortization of $14.7 million and $9.7 million at December 31, 2015 and 2014, respectively.

The aggregate amount of amortization expense for the Company’s core deposit and bank charter intangibles is expected to be $6.2 million in 2016, $5.9 million in 2017, $5.9 million in 2018, $5.5 million in 2019 and $3.0 million in 2020.

Stock-based compensation – The Company has a non-qualified employee stock option plan, a non-employee director stock plan and an employee restricted stock plan, each of which is described more fully in Note 16. The Company measures the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. Such cost is recognized over the vesting period of the award.

Earnings per common share – Earnings per common share are computed using the two-class method. Basic earnings per common share are computed by dividing net income available to common stockholders by the weighted-average number of common shares outstanding during the applicable period. Diluted earnings per common share are computed by dividing net income available to common stockholders by the weighted-average number of common shares outstanding after consideration of the dilutive effect, if any, of the Company’s common stock options using the treasury stock method. The Company has determined that its outstanding non-vested stock awards granted under its restricted stock plan are participating securities.

Segment disclosures – The Company operates in only one segment – community banking. Accordingly, there is no requirement to report segment information in the Company’s Consolidated Financial Statements. No revenues are derived from foreign countries and no single external customer comprises more than 10% of the Company’s revenues.

Recent accounting pronouncements – In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers.” ASU 2014-09 provides guidance that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. In August 2015, the FASB issued ASU 2015-14, which defers the effective date of this standard to annual and interim periods beginning after December 15, 2017; however, early adoption is permitted for annual and interim reporting periods beginning after December 15, 2016. The Company is currently

99

evaluating the impact, if any, ASU 2014-09 will have on its financial position, results of operations, and its financial statement disclosures.

In June 2014, the FASB issued ASU 2014-11 “Transfers and Servicing (Topic 860).” ASU 2014-11 amends the accounting guidance for repo-to-maturity transactions and requires such transactions to be accounted for as secured borrowings. In addition, ASU 2014-11 requires enhanced disclosures related to the collateral pledged, maturity and risk associated with repurchase agreements. The Company adopted the provision of ASU 2014-11 beginning April 1, 2015. The adoption of ASU 2014-11 did not have a significant impact on the Company’s financial position or results of operations but did require additional disclosures about the Company’s repurchase agreements.

In January 2015, the FASB issued ASU 2015-01, “Income Statement – Extraordinary and Unusual Items (Subtopic 225-20) – Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items.” ASU 2015-01 eliminates from GAAP the concept of extraordinary items, which, among other things, required an entity to segregate extraordinary items considered to be unusual and infrequent from the results of ordinary operations and show the item separately in the income statement, net of tax, after income from continuing operations. ASU 2015-01 is effective for interim and annual periods beginning after December 15, 2015. ASU 2015-01 is not expected to have a significant impact on the Company’s financial position, results of operations, or its financial statement disclosures.

In February 2015, the FASB issued ASU 2015-02, “Consolidation (Topic 810): Amendments to the Consolidation Analysis” which amends the consolidation requirements of ASU 810 by changing the consolidation analysis required under GAAP. The revised guidance amends the consolidation analysis based on certain fee arrangements or relationships to the reporting entity and, for limited partnerships, requires entities to consider the limited partner’s rights relative to the general partner. ASU 2015-02 is effective for annual and interim periods beginning after December 15, 2015. ASU 2015-02 is not expected to have a significant impact on the Company’s financial position, results of operations, or its financial statement disclosures.

In April 2015, the FASB issued ASU 2015-03, “Interest – Imputation of Interest (Subtopic 835-30) – Simplifying the Presentation of Debt Issuance Costs.” ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in ASU 2015-03. In August 2015, the FASB issued ASU 2015-15 to clarify the Securities and Exchange Commission (“SEC”) staff’s position on presenting and measuring debt issue costs related to line-of-credit arrangements.  ASU 2015-03 and ASU 2015-15 are effective for interim and annual periods beginning after December 15, 2015. ASU 2015-03 and ASU 2015-15 are not expected to have a significant impact on the Company’s financial position, results of operations, or its financial statement disclosures.

In September 2015, the FASB issued ASU 2015-16 “Simplifying the Accounting for Measurement-Period Adjustments.”  ASU 2015-16 requires entities to recognize measurement period adjustments during the reporting period in which the adjustments are determined.  The income effects, if any, of a measurement period adjustment are cumulative and are to be reported in the period in which the adjustment to a provisional amount is determined.  Also, ASU 2015-16 requires presentation on the face of the income statement or in the notes, the effect of the measurement period adjustment as if the adjustment had been recognized at acquisition date.  ASU 2015-16 is effective for fiscal periods beginning after December 15, 2016 and should be applied prospectively to measurement period adjustments that occur after the effective date.

In January 2016, FASB issued ASU 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities.” ASU 2016-01 revises the accounting for the classification and measurement of investments in equity securities and revises the presentation of certain fair value changes for financial liabilities measured at fair value.  For equity securities, the guidance in ASU 2016-01 requires equity investments to be measured at fair value with changes in fair value recognized in net income.  For financial liabilities that are measured at fair value in accordance with the fair value option, the guidance requires presenting, in other comprehensive income, the change in fair value that relates to a change in instrument-specific credit risk. ASU 2016-01 also eliminates the disclosure assumptions used to estimate fair value for financial instruments measured at amortized cost and requires disclosure of an exit price notion in determining the fair value of financial instruments measured at amortized cost.  ASU 2016-01 is effective for interim and annual periods beginning after December 15, 2017.  The Company is evaluating the impact, if any, that ASU 2016-01 will have on its financial position, results of operations, and its financial statement disclosures.

Proposed Accounting Pronouncements – In December 2012, the FASB announced a project related to the impairment of financial instruments in an effort to provide new guidance that would significantly change how entities measure and recognize credit impairment for certain financial assets.  While completion of the project and related guidance is still pending, it is anticipated that new guidance will replace the current incurred loss model that is utilized in estimating the ALLL with a model that requires management to estimate all contractual cash flows that are not expected to be collected over the life of the loan. The FASB describes this revised model as the current expected credit loss (“CECL”) model and believes the CECL model will result in more timely recognition of

100

credit losses since the CECL model incorporates expected credit losses versus incurred credit losses.  The proposed scope of FASB’s CECL model would include loans, held-to-maturity debt instruments, lease receivables, loan commitments and financial guarantees that are not accounted for at fair value.  The final issuance date and the implementation date of the CECL guidance is currently pending, and the Company will continue to monitor FASB’s progress on this project.  

Reclassifications and recasts – Certain reclassifications of prior years’ amounts have been made to conform with the 2015 financial statements presentation. These reclassifications had no impact on prior years’ net income, as previously reported. During the second and fourth quarter of 2015, the Company revised its initial estimates regarding the expected recovery of certain acquired loans and deferred tax assets in its February 10, 2015 acquisition of Intervest. As a result, certain amounts previously reported in the Company’s 2015 interim consolidated financial statements have been recast.

2. Acquisitions

Bank of the Carolinas

On August 5, 2015, the Company completed its acquisition of Bank of the Carolinas Corporation (“BCAR”) and its wholly-owned subsidiary Bank of the Carolinas for an aggregate of 1,447,620 shares of its common stock (plus cash in lieu of fractional shares) in a transaction valued at approximately $65.4 million. The acquisition of BCAR expands the Company’s operations in North Carolina by adding eight retail banking offices, including one office each in Advance, Asheboro, Concord, Harrisburg, Landis, Lexington, Mocksville and Winston-Salem. As a result of the BCAR acquisition, the Company acquired total assets with an estimated fair value of $351.3 million, total loans with an estimated fair value of $266.2 million and total deposits with an estimated fair value of $288.9 million.  Goodwill of $4.8 million, which is the excess of the merger consideration over the estimated fair value of net assets acquired, was recorded in the BCAR acquisition and is the result of expected operational synergies, expansion of banking services in the Piedmont Triad region of North Carolina and other factors.  This goodwill is not expected to be deductible for tax purposes.

Intervest Bancshares Corporation

On February 10, 2015, the Company completed its acquisition of Intervest and its wholly-owned bank subsidiary Intervest National Bank, for an aggregate of 6,637,243 shares of its common stock (plus cash in lieu of fractional shares) in a transaction valued at approximately $238.5 million. The acquisition of Intervest provided the Company with a retail banking office in New York City and expanded its service area in Florida by adding five retail banking offices in Clearwater, Florida and one retail banking office in South Pasadena, Florida. During the third quarter of 2015, the Company closed one of the acquired retail banking offices in Clearwater, Florida.  During the fourth quarter of 2015, the Company eliminated the New York lending operations acquired in the Intervest acquisition.  Also, during the second and fourth quarters of 2015, management revised its initial estimates and assumptions regarding the recovery of certain acquired loans and acquired deferred tax assets.  Because such revision occurred during the first 12 months following the date of acquisition and was not the result of a change in circumstances, management has decreased the goodwill recorded in the Intervest transaction by $4.9 million to reflect this change in estimate.  

101

The following table provides a summary of the assets acquired and liabilities assumed as recorded by Intervest, the fair value adjustments necessary to adjust those acquired assets and assumed liabilities to estimated fair value, the recast adjustments described above and the estimates of the resultant fair values of those assets and liabilities as recorded by the Company. As provided for under GAAP, management has up to 12 months following the date of acquisition to finalize the fair values of the acquired assets and assumed liabilities. Once management has finalized the fair values of acquired assets and assumed liabilities within this 12-month period, management considers such values to be the Day 1 Fair Values.  The fair values shown in the following table have been determined by management to be the Day 1 Fair Values.

In evaluating the Company’s unrealized loss positions for other-than-temporary impairment for its investment securities portfolio, management considers the credit quality of the issuer, the nature and cause of the unrealized loss, the severity and duration of the impairments and other factors. At December 31, 2015 and 2014, management determined the unrealized losses were the result of fluctuations in interest rates and did not reflect deteriorations of the credit quality of the investments. Accordingly, management believes that all of its unrealized losses on investment securities are temporary in nature. The Company does not have the intent to sell

104

these investment securities and more likely than not, would not be required to sell these investment securities before fair value recovers to amortized cost.

The following table is a maturity distribution of investment securities AFS as of December 31, 2015.

As of December 31, 2015 and 2014, the Company had identified purchased loans where management had determined it was probable that the Company would be unable to collect all amounts according to the contractual terms thereof (for purchased loans without evidence of credit deterioration at date of acquisition) or the expected performance of such loans had deteriorated from management’s performance expectations established in conjunction with the determination of the Day 1 Fair Values or since management’s most recent review of such portfolio’s performance (for purchased loans with evidence of credit deterioration at date of acquisition). As a result the Company recorded net charge-offs totaling $2.5 million during 2015 and $3.2 million during 2014 for such loans. The Company also recorded $2.5 million during 2015 and $3.2 million during 2014 of provision for loan and lease losses to cover these charge-offs. Also, the Company recorded $1.2 million of additional provision in 2015 (none in 2014) to absorb probable incurred losses in its purchased loan portfolio that had not previously been charged off.  Additionally, the Company transferred certain of these purchased loans to foreclosed assets. As a result of these actions, the Company had $8.1 million of impaired purchased loans at December 31, 2015 and $14.0 million of impaired purchased loans at December 31, 2014.

Management has determined that certain of the Company’s impaired loans and leases do not require any specific allowance at December 31, 2015 and 2014 because (i) management’s analysis of such individual loans and leases resulted in no impairment or (ii) all identified impairment on such loans and leases has previously been charged off.

Interest income on impaired loans and leases is recognized on a cash basis when and if actually collected. Total interest income recognized on impaired loans and leases for the years ended December 31, 2015, 2014 and 2013 was not material.

(1) The Company does not risk rate its residential 1-4 family loans, its consumer loans, and certain “other” loans. However, for purposes of the above table, the Company considers such loans to be (i) satisfactory – if they are performing and less than 30 days past due, (ii) watch – if they are performing and 30 to 89 days past due or (iii) substandard – if they are nonperforming or 90 days or more past due.

The following categories of credit quality indicators are used by the Company.

Satisfactory – Loans and leases in this category are considered to be a satisfactory credit risk and are generally considered to be collectible in full.

Moderate – Loans and leases in this category are considered to be a marginally satisfactory credit risk and are generally considered to be collectible in full.

Watch – Loans and leases in this category are presently protected from apparent loss, however weaknesses exist which could cause future impairment of repayment of principal or interest.

Substandard – Loans and leases in this category are characterized by deterioration in quality exhibited by a number of weaknesses requiring corrective action and posing risk of some loss.

proceeds from the 2004 Securities were used to purchase an equal principal amount of adjustable rate subordinated debentures of the Company that bear interest, adjustable quarterly, at 90-day LIBOR plus 2.22% (“2004 Debentures”).

On September 29, 2006, Ozark V sold to investors in a private placement offering $20 million of adjustable rate trust preferred securities (“2006 Securities”).

On February 10, 2015, in conjunction with the Intervest acquisition, the Company acquired Intervest II, Intervest III, Intervest IV and Intervest V with outstanding subordinated debentures totaling $56.7 million and related trust preferred securities totaling $55.0 million. On the date of such acquisition, the Company recorded the assumed subordinated debentures owed to the Intervest Trusts at estimated fair value of $52.2 million, based on an independent third party valuation, to reflect a current market interest rate for comparable obligations. The fair value adjustment of $4.5 million is being amortized, using a level-yield methodology over the estimated holding period of approximately eight years, as an increase in interest expense of the subordinated debentures owed to the Intervest Trusts. In addition to the subordinated debentures of the Intervest Trusts, the Company also acquired $1.7 million of trust common equity issued by the Intervest Trusts.

At December 31, 2015, the Company had an aggregate of $121.7 million of subordinated debentures outstanding (with an aggregate carrying value of $117.7 million) and had an asset of $3.7 million representing its investment in the common equity issued by the Trusts. The sole assets of the Trusts are the adjustable rate debentures and the liabilities of the Trusts are the trust preferred securities. At December 31, 2015 and 2014, the Trusts had aggregate common equity of $3.7 million and $1.9 million, respectively, and did not have any restricted net assets. The Company has, through various contractual arrangements or by operation of law, fully and unconditionally guaranteed all obligations of the Trusts with respect to the trust preferred securities. Additionally, there are no restrictions on the ability of the Trusts to transfer funds to the Company in the form of cash dividends, loans or advances. The Company has the option to defer interest payments on the subordinated debentures from time to time for a period not to exceed five consecutive years.

401(k) Plan also apply. Matching contributions made by the Company prior to the 401(k) Plan becoming a Safe-Harbor CODA vest over six years and are held in trust until distributed pursuant to the terms of the 401(k) Plan.

Contributions to the 401(k) Plan are invested in accordance with participant elections among certain investment options. Distributions from participant accounts are not permitted before age 65, except in the event of death, permanent disability, certain financial hardships or termination of employment. The Company made matching cash contributions to the 401(k) Plan during 2015, 2014 and 2013 of $2.7 million, $2.3 million and $1.8 million, respectively.

The Company also maintains the Bank of the Ozarks, Inc. Deferred Compensation Plan (the “Plan”), which is an unfunded deferred compensation arrangement for the group of employees designated as key employees, including certain of the Company’s executive officers. Under the terms of the Plan, eligible participants may elect to defer a portion of their compensation. Such deferred compensation is distributable in lump sum or specified installments upon separation from service with the Company or upon other specified events as defined in the Plan. Prior to 2013, the Company had the ability to make a contribution to each participant’s account, limited to one half of the first 6% of compensation deferred by the participant and subject to certain other limitations. Effective January 1, 2013, the Plan was amended such that the Company no longer makes any contribution to the Plan for the benefit of each participant or otherwise. Amounts deferred under the Plan are invested in certain approved investments (excluding securities of the Company or its affiliates). At both December 31, 2015 and 2014, the Company had Plan assets, along with an equal amount of liabilities, totaling $4.2 million, recorded on the accompanying consolidated balance sheet.

Effective May 4, 2010, the Company established a Supplemental Executive Retirement Plan (“SERP”) and certain other benefit arrangements for its Chairman and Chief Executive Officer. Pursuant to the SERP, this officer is entitled to receive 180 equal monthly payments of $32,197, or $386,360 annually, commencing at the later of obtaining age 70 or separation from service. If separation from service occurs prior to age 70, such benefit will be at a reduced amount. The costs of such benefits, assuming a retirement date at age 70, will be fully accrued by the Company at such retirement date. During 2015, 2014 and 2013, respectively, the Company accrued $223,000, $200,000 and $180,000 for the future benefits payable under the SERP. The SERP is an unfunded plan and is considered a general contractual obligation of the Company.

16. Stock-Based Compensation

The Company has a nonqualified stock option plan for certain key employees and officers of the Company. This plan provides for the granting of nonqualified options to purchase shares of common stock in the Company. No option may be granted under this plan for less than the fair market value of the common stock, defined by the plan as the average of the highest reported asked price and the lowest reported bid price, on the date of the grant. The benefits or amounts that may be received by or allocated to any particular officer or employee of the Company under this plan will be determined in the sole discretion of the Company’s board of directors or its personnel and compensation committee. All employee options outstanding at December 31, 2015 were issued with a vesting period of three years and expire seven years after issuance. At December 31, 2015 there were 1,319,549 shares available for future grants under this plan.

During 2015, the Company adopted the Bank of the Ozarks, Inc. Non-Employee Director Stock Plan (the “Director Plan”) that provides for awards of common stock to eligible non-employee directors. The Director Plan grants to each director who is not otherwise an employee of the Company, or any subsidiary, shares of common stock on the day of his or her election as director of the Company at each annual shareholders meeting, or any special meeting called for the purpose of electing a director or directors of the Company, and upon appointment for the first time as director of the Company. The number of shares of common stock to be awarded will be the equivalent of $25,000 worth of shares of common stock based on the average of the highest reported asked price and lowest reported bid price on the grant date. The common stock awarded under this plan is fully vested on the grant date. The aggregate number of shares of common stock which may be issued as awards under this plan will not exceed 50,000 shares, subject to certain adjustments. During 2015, the Company issued 7,657 shares of common stock and incurred $0.3 million in stock-based compensation expense related to common stock awards issued under the Director Plan.

Prior to the adoption of the Director Plan, the Company had a nonqualified stock option plan for non-employee directors. No options were granted under this plan during 2015. All options previously granted under this plan were exercisable immediately and expire ten years after issuance.

121

The following table summarizes stock option activity for both the employee and non-employee director stock option plans for the year ended December 31, 2015.

	Options			Weighted- Average Exercise Price/Share		Weighted- Average Remaining Contractual Life (in years)		Aggregate Intrinsic Value (in thousands)
Outstanding – January 1, 2015		1,859,350		$	23.49
Granted		659,181			52.94
Exercised		(365,375	)		14.08
Forfeited		(118,680	)		27.56
Outstanding – December 31, 2015		2,034,476			34.50		5.6	$	32,717	(1)
Fully vested and exercisable at December 31, 2015		456,625		$	14.92		4.1	$	15,711	(1)
Expected to vest in future periods		1,362,745
Fully vested and expected to vest at December 31, 2015(2)		1,819,370		$	33.29		5.5	$	31,245	(1)

(1) Based on closing price of $49.46 per share on December 31, 2015.

(2) At December 31, 2015 the Company estimates that options to purchase 215,106 shares of the Company’s common stock will not vest and will be forfeited prior to their vesting date.

Intrinsic value for stock options is defined as the amount by which the current market price of the underlying stock exceeds the exercise price. For those stock options where the exercise price exceeds the current market price of the underlying stock, the intrinsic value is zero. The total intrinsic value of options exercised during 2015, 2014 and 2013 was $12.5 million, $10.0 million and $7.7 million, respectively.

Options to purchase 659,181 shares, 616,250 shares and 526,000 shares, respectively, were granted during 2015, 2014 and 2013 with a weighted-average grant date fair value of $14.00, $7.04 and $5.61, respectively. The fair value for each option grant is estimated on the date of grant using the Black-Scholes option pricing model.

The following table is a summary of the weighted-average assumptions used in the Black-Scholes option pricing model for the years indicated.

	Year Ended December 31,
	2015			2014			2013
Risk-free interest rate		1.69	%		1.62	%		1.30	%
Expected dividend yield		1.19	%		1.49	%		1.85	%
Expected stock volatility		31.0	%		24.1	%		30.2	%
Expected life (years)		5.0			5.0			5.0

The Company uses the U.S. Treasury yield curve in effect at the time of the grant to determine the risk-free interest rate. The expected dividend yield is estimated using the current annual dividend level and recent stock price of the Company’s common stock at the date of grant. Expected stock volatility is based on historical volatilities of the Company’s common stock. The expected life of the options is calculated based on the “simplified” method as provided for under SEC Staff Accounting Bulletin No. 110.

The total fair value of options to purchase shares of the Company’s common stock that vested during 2015, 2014 and 2013 was $2.0 million, $1.5 million and $1.2 million, respectively. Stock-based compensation expense for stock options included in non-interest expense was $2.6 million, $2.1 million and $1.7 million for 2015, 2014 and 2013, respectively. Total unrecognized compensation cost related to non-vested stock option grants was $9.7 million at December 31, 2015 and is expected to be recognized over a weighted-average period of 2.5 years.

The Company has a restricted stock and incentive plan that permits issuance of up to 1,600,000 shares of restricted stock or restricted stock units. All officers and employees of the Company are eligible to receive awards under the restricted stock and incentive plan. The benefits or amounts that may be received by or allocated to any particular officer or employee of the Company under the restricted stock and incentive plan will be determined in the sole discretion of the Company’s board of directors or its personnel and compensation committee. Shares of common stock issued under the restricted stock and incentive plan may be shares of original issuance, shares held in treasury or shares that have been reacquired by the Company. At December 31, 2015 there were 576,325 shares available for future grants under this plan.

122

The following table summarizes non-vested restricted stock activity for the year ended December 31, 2015.

	Shares
Outstanding – January 1, 2015		444,700
Granted		245,300
Forfeited		(41,325	)
Earned and issued		(213,200	)
Outstanding – December 31, 2015		435,475
Weighted-average grant date fair value	$	29.87

Restricted stock awards of 245,300 shares were granted during 2015 with a weighted-average grant date fair value of $34.39. No restricted stock awards were granted during 2014. The fair value of the restricted stock awards is amortized to compensation expense over the vesting period (generally three years) and is based on the market price of the Company’s common stock at the date of grant multiplied by the number of shares granted that are expected to vest. Stock-based compensation expense for restricted stock included in non-interest expense was $5.2 million, $3.5 million and $2.8 million for 2015, 2014 and 2013, respectively. Unrecognized compensation expense for nonvested restricted stock awards was $6.8 million at December 31, 2015 and is expected to be recognized over a weighted-average period of 1.8 years.

On January 13, 2016 the Company’s personnel and compensation committee approved the issuance of restricted stock awards for 212,907 shares of restricted common stock that vest on January 13, 2019. Total compensation expense for the restricted stock awards is expected to be approximately $9.1 million and is expected to be recognized ratably over the three-year vesting period.

17. Commitments and Contingencies

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 primarily include standby letters of credit and commitments to extend credit.

Outstanding standby letters of credit are contingent commitments issued by the Company generally to guarantee the performance of a customer in third party borrowing arrangements. The terms of the letters of credit are generally for a period of one year. The maximum amount of future payments the Company could be required to make under these letters of credit at December 31, 2015 and 2014 is $16.5 million and $4.5 million, respectively. The Company holds collateral to support letters of credit when deemed necessary. The total of collateralized commitments at December 31, 2015 and 2014 was $15.9 million and $4.3 million, respectively.

The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit is represented by the contractual amount of those instruments. The Company has the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments.

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 these commitments may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the counterparty. The type of collateral held varies but may include accounts receivable, inventory, property, plant and equipment, and other real or personal property.

123

At December 31, 2015, the Company had outstanding commitments to extend credit, excluding mortgage interest rate lock commitments, totaling $5.8 billion. The following table shows the contractual maturities of outstanding commitments to extend credit at December 31, 2015.

Maturity	Contractual Maturities at December 31, 2015

The Company had outstanding commitments to extend credit to related parties totaling $6.0 million and $5.3 million at December 31, 2015 and 2014, respectively.

19. Regulatory Matters

The Company is subject to various regulatory capital requirements administered by federal and state banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s financial condition and results of operations. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company must meet specific capital guidelines that involve quantitative measures of the Company’s assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. The Company’s capital amounts and classification are also subject to qualitative judgments by the regulators about component risk weightings and other factors.

The FDIC and other federal banking regulators revised the risk-based capital requirements applicable to bank holding companies and insured depository institutions, including the Company and the Bank, to make them consistent with agreements that were reached by the Basel Committee on Banking Supervision (“Basel III”) and certain provisions of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Basel III Rules”). The Basel III Rules became effective for the Company and the Bank on January 1, 2015 (subject to a phase-in period for certain provisions). The Basel III Rules require the maintenance of minimum amounts and ratios (set forth in the following table) of common equity tier 1 capital, tier 1 capital and total capital (as defined in the regulations) to risk-weighted assets (as defined), and of tier 1 capital to adjusted quarterly average assets (as defined).

Under the Basel III Rules, common equity tier 1 capital consists of common stock and paid-in capital (net of treasury stock) and retained earnings. Common equity tier 1 capital is reduced by goodwill, certain intangible assets, net of associated deferred tax liabilities, deferred tax assets that arise from tax credit and net operating loss carryforwards, net of any valuation allowance, and certain other items as specified by the Basel III Rules.

124

Tier 1 capital includes common equity tier 1 capital and certain additional tier 1 items as provided under the Basel III Rules. The tier 1 capital for the Company consists of common equity tier 1 capital and $118 million of trust preferred securities issued by the Trusts. The Basel III Rules include certain provisions that would require trust preferred securities to be phased out of qualifying tier 1 capital. Currently, the Company’s trust preferred securities are grandfathered under the Basel III Rules and will continue to be included as tier 1 capital. However, should the Company exceed $15 billion in total assets, the grandfather provisions applicable to its trust preferred securities would no longer apply and such trust preferred securities would no longer be included as tier 1 capital, but would continue to be included as total capital. The common equity tier 1 capital and the tier 1 capital are the same for the Bank.

Basel III Rules allow for insured depository institutions to make a one-time election not to include most elements of accumulated other comprehensive income in regulatory capital and instead effectively use the existing treatment under the general risk-based capital rules. The Company and Bank made this opt-out election to avoid significant variations in the level of capital depending upon the impact of interest rate fluctuations on the fair value of its investments securities portfolio.

Total capital includes tier 1 capital and tier 2 capital. Tier 2 capital includes, among other things, the allowable portion of the ALLL and any trust preferred securities that are excluded from tier 1 capital.

The Basel III Rules also changed the risk-weights of assets in an effort to better reflect credit risk and other risk exposures. These include a 150% risk weight (up from 100%) for certain high volatility commercial real estate acquisition, development and construction loans and the unsecured portion of non-residential mortgage loans that are 90 days past due or otherwise on nonaccrual status; a 20% (up from 0%) credit conversion factor for the unused portion of a commitment with an original maturity of one year or less that is not unconditionally cancellable; a 250% risk weight (up from 100%) for mortgage servicing rights and deferred tax assets that are not deducted from capital; and increased risk weights (from 0% to up to 600%) for equity exposures.

The common equity tier 1 capital, tier 1 capital and total capital ratios are calculated by dividing the respective capital amounts by risk-weighted assets. The leverage ratio is calculated by dividing tier 1 capital by adjusted quarterly average total assets.

The Basel III Rules limit capital distributions and certain discretionary bonus payments if the banking organization does not hold a “capital conservation buffer” consisting of 2.5% of common equity tier 1 capital, tier 1 capital and total capital to risk-weighted assets in addition to the amount necessary to meet minimum risk-based capital requirements. The capital conservation buffer will be phased in beginning January 1, 2016, at 0.625% of risk-weighted assets, increasing each year by that amount until fully implemented at 2.5% on January 1, 2019. When fully phased in on January 1, 2019, the Basel III Rules will require the Company and Bank to maintain (i) a minimum ratio of common equity tier 1 capital to risk-weighted assets of at least 4.5%, plus a 2.5% capital conservation buffer, which effectively results in a minimum ratio of 7.0% upon full implementation, (ii) a minimum ratio of tier 1 capital to risk-weighted assets of at least 6.0%, plus a 2.5% capital conservation buffer, which effectively results in a minimum ratio of 8.50% upon full implementation, (iii) a minimum ratio of total capital to risk-weighted assets of at least 8.0%, plus a 2.5% capital conservation buffer, which effectively results in a minimum ratio of 10.5% upon full implementation and (iv) a minimum leverage ratio of at least 4.0%.

Prior to January 1, 2015, federal and state regulatory agencies required the Company and the Bank to maintain minimum Tier 1 and total capital to risk-weighted assets of 4.0% and 8.0%, respectively, and Tier 1 capital to average quarterly assets (Tier 1 leverage ratio) of at least 3.0%. Tier 1 capital consisted of common equity, retained earnings, certain types of preferred stock, qualifying minority interest and trust preferred securities, subject to limitations, and excluded goodwill and various intangible assets. Total capital included Tier 1 capital, any amounts of trust preferred securities excluded from Tier 1 capital, and the lesser of the ALLL or 1.25% of risk-weighted assets.

125

The following table presents actual and required capital ratios as of December 31, 2015 for the Company and the Bank under the Basel III Rules. The minimum required capital amounts presented include the minimum required capital levels as of December 31, 2015 based on the current phase-in provisions of the Basel III Rules and the minimum required capital levels as of January 1, 2019 when the Basel III Rules have been fully phased-in. Capital levels required to be considered well capitalized are based upon prompt corrective action regulations, as amended to reflect the changes under the Basel III Rules.

As of December 31, 2015 and 2014, the most recent notification from the regulators categorized the Company and the Bank as well capitalized under the regulatory framework for prompt corrective action. There are no conditions or events since that notification that management believes have changed the Company’s or the Bank’s category.

The state bank commissioner’s approval is required before the Bank can declare and pay any dividend of 75% or more of the net profits of the Bank after all taxes for the current year plus 75% of the retained net profits for the immediately preceding year. At December 31, 2015 and 2014, respectively, $117.8 million and $18.8 million were available for payment of dividends by the Bank without the approval of regulatory authorities.

126

Under FRB regulation, the Bank is also limited as to the amount it may loan to its affiliates, including the Company, and such loans must be collateralized by specific types of collateral. The maximum amount available for loan from the Bank to the Company is limited to 10% of the Bank’s capital and surplus or approximately $155 million and $93 million, respectively, at December 31, 2015 and 2014.

20. Fair Value Measurements

The Company measures certain of its assets and liabilities on a fair value basis using various valuation techniques and assumptions, depending on the nature of the asset or liability. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Additionally, fair value is used either annually or on a non-recurring basis to evaluate certain assets and liabilities for impairment or for disclosure purposes. At December 31, 2015 and 2014, the Company had no liabilities that were accounted for at fair value.

The Company applies the following fair value hierarchy.

Level 1 – Quoted prices for identical instruments in active markets.

Level 2 – Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable.

Level 3 – Instruments whose inputs are unobservable.

The following table sets forth the Company’s assets, as of the date indicated, that are accounted for at fair value.

(1) The Company utilizes valuation techniques consistent with the market, cost, and income approaches, or a combination thereof in determining fair value.

The following methods and assumptions are used to estimate the fair value of the Company’s assets that are accounted for at fair value.

Investment securities – The Company utilizes independent third parties as its principal sources for determining fair value of investment securities which are measured on a recurring basis. As a result, the Company receives estimates of fair values from at least two independent pricing sources for the majority of its individual securities within its investment portfolio. For investment securities traded in an active market, the fair values are obtained from independent pricing services and are based on quoted market prices if available. If quoted market prices are not available, fair values are based on market prices for comparable securities, broker quotes or comprehensive interest rate tables, pricing matrices or a combination thereof. For investment securities traded in a market that is not active, fair value is determined using unobservable inputs. All fair value estimates of the Company’s investment securities are reviewed and approved on a quarterly basis by the Company’s Investment Portfolio Manager and its Chief Financial Officer.

The Company has determined that certain of its investment securities had a limited to non-existent trading market at December 31, 2015 and 2014. As a result, the Company considers these investments as Level 3 in the fair value hierarchy. Specifically the fair values of certain obligations of state and political subdivisions consisting of certain unrated private placement bonds (the “private placement bonds”) in the amount of $18.5 million and $19.4 million at December 31, 2015 and 2014, respectively, were calculated using Level 3 hierarchy inputs and assumptions as the trading market for such securities was determined to be “not active.” This determination was based on the limited number of trades or, in certain cases, the existence of no reported trades for the private placement bonds. The private placement bonds are generally prepayable at par value at the option of the issuer. As a result, management believes the private placement bonds should be valued at the lower of (i) the matrix pricing provided by the Company’s third party pricing services for comparable unrated municipal securities or (ii) par value. At December 31, 2015 and 2014, the third party pricing matrices valued the Company’s total portfolio of private placement bonds at $18.5 million and $19.4 million, respectively, which was equal to the par value of the private placement bonds at December 31, 2015 and 2014. Accordingly, at December 31, 2015 and 2014 the Company reported the private placement bonds at $18.5 million and $19.4 million, respectively.

Impaired non-purchased loans and leases – Fair values are measured on a non-recurring basis based on the underlying collateral value of the impaired loan or lease, reduced for holding and selling costs, or the estimated discounted cash flows for such loan or lease. The Company has reduced the carrying value of its impaired non-purchased loans and leases (all of which are included in nonaccrual loans and leases) by $7.8 million and $5.9 million, respectively, to the estimated fair value of $9.3 million and $19.5 million, respectively, for such loans and leases at December 31, 2015 and 2014. These adjustments to reduce the carrying value of impaired non-purchased loans and leases to estimated fair value at December 31, 2015 and 2014 consisted of $6.5 million and $4.8 million, respectively, of partial or full charge-offs and $1.3 million and $1.1 million, respectively, of specific loan and lease loss allocations.

128

Impaired purchased loans – Impaired purchased loans are measured at fair value on a non-recurring basis. At December 31, 2015 and 2014, the Company had identified purchased loans where management had determined it was probable that the Company would be unable to collect all amounts according to the contractual terms thereof (for purchased loans without evidence of credit deterioration at date of acquisition) or the expected performance of such loans had deteriorated from management’s performance expectations established in conjunction with the determination of the Day 1 Fair Values or since management’s most recent review of such portfolio’s performance (for purchased loans with evidence of credit deterioration at date of acquisition). As a result the Company recorded net charge-offs, totaling $2.5 million during 2015 and $3.2 million during 2014 for such loans. The Company recorded $2.5 million during 2015 and $3.2 million during 2014 of provision for loan and lease losses to cover these charge-offs. Also, the Company recorded $1.2 million of additional provision in 2015 (none in 2014) for loan and lease losses to absorb probable incurred losses in its purchased loan portfolio that had not previously been charged off. Additionally, the Company transferred certain of these purchased loans to foreclosed assets. As a result of these actions, the Company had $8.1 million of impaired purchased loans at December 31, 2015 and $14.0 million of impaired purchased loans at December 31, 2014.

Foreclosed assets – Repossessed personal properties and real estate acquired through or in lieu of foreclosure, excluding purchased foreclosed assets, are initially recorded at the lesser of current principal investment or fair value less estimated cost to sell (generally 8% to 10%) at the date of repossession or foreclosure. Purchased foreclosed assets are initially recorded at Day 1 Fair Values. In estimating such Day 1 Fair Values, management considered a number of factors including, among others, appraised value, estimated selling price, estimated holding periods and net present value (calculated using discount rates ranging from 8.0% to 9.5% per annum) of cash flows expected to be received.

Valuations of all foreclosed assets are periodically reviewed by management with the carrying value of such assets adjusted through non-interest expense to the then estimated fair value, generally based on third party appraisals, broker price opinions or other valuations of the property, net of estimated selling costs, if lower, until disposition.

The following table presents additional information for the periods indicated about assets measured at fair value on a recurring basis and for which the Company has utilized Level 3 inputs to determine fair value.

21. Fair Value of Financial Instruments

The following methods and assumptions were used to estimate the fair value of financial instruments.

Cash and due from banks – For these short-term instruments, the carrying amount is a reasonable estimate of fair value.

Investment securities – The Company utilizes independent third parties as its principal sources for determining fair value of investment securities which are measured on a recurring basis. As a result, the Company receives estimates of fair values from at least two independent pricing sources for the majority of its individual securities within its investment portfolio. For investment securities traded in an active market, the fair values are obtained from independent pricing services and are based on quoted market prices if available. If quoted market prices are not available, fair values are based on market prices for comparable securities, broker quotes,

129

comprehensive interest rate tables, pricing matrices or a combination thereof. For investment securities traded in a market that is not active, fair value is determined using unobservable inputs. All fair value estimates of the Company’s investment securities are reviewed and approved on a quarterly basis by the Company’s Investment Portfolio Manager and its Chief Financial Officer. The Company’s investments in the common stock of the FHLB and FNBB of $23.5 million and $14.2 million at December 31, 2015 and 2014 do not have readily determinable fair values and are carried at cost.

Loans and leases – The fair value of loans and leases, including purchased loans, is estimated by discounting the future cash flows using the current rate at which similar loans or leases would be made to borrowers or lessees with similar credit ratings and for the same remaining maturities.

Deposit liabilities – The fair value of demand deposits, savings accounts, money market deposits and other transaction accounts is the amount payable on demand at the reporting date. The fair value of fixed maturity time deposits is estimated using the rate currently available for deposits of similar remaining maturities.

Repurchase agreements – For these short-term instruments, the carrying amount is a reasonable estimate of fair value.

Other borrowed funds – For these short-term instruments, the carrying amount is a reasonable estimate of fair value. The fair value of long-term instruments is estimated based on the current rates available to the Company for borrowings with similar terms and remaining maturities.

Subordinated debentures – The fair values of these instruments are based primarily upon discounted cash flows using rates for securities with similar terms and remaining maturities.

Off-balance sheet instruments – The fair values of commercial loan commitments and letters of credit are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements. The fair values of commercial loan commitments and letters of credit were not material at December 31, 2015 and 2014.

The fair values of certain of these instruments were calculated by discounting expected cash flows, which contain numerous uncertainties and involve significant judgments by management. Fair value is the estimated amount at which financial assets or liabilities could be exchanged in a current transaction between willing parties other than in a forced or liquidation sale. Because no market exists for certain of these financial instruments and because management does not intend to sell these financial instruments, the Company does not know whether the fair values shown below represent values at which the respective financial instruments could be sold individually or in the aggregate.

The following table presents the carrying amounts and estimated fair values as of the dates indicated and the fair value hierarchy of the Company’s financial instruments.

Report of Independent Registered Public Accounting Firm on Internal Control Over Financial Reporting

Board of Directors and Stockholders

Bank of the Ozarks, Inc.

We have audited Bank of the Ozarks, Inc.’s internal control over financial reporting as of December 31, 2015, based on criteria established in the 2013 Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Bank of the Ozarks, Inc.’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 Report of Management on the Company’s 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 accounting principles generally accepted in the United States of America. 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.

As permitted, the Company excluded the operations of the financial institutions acquired during 2015, which is described in Note 2 of the Consolidated Financial Statements, from the scope of management’s report on internal control over financial reporting. As such they have also been excluded from the scope of our audit of internal control over financial reporting.

In our opinion, Bank of the Ozarks, Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2015, based on the 2013 Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Bank of the Ozarks, Inc. as of December 31, 2015 and 2014 and the related consolidated statements of income, comprehensive income, stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2015, and our report dated February 19, 2016, expressed an unqualified opinion thereon.

Report of Management on the Company’s Internal Control Over Financial Reporting

February 19, 2016

Management of Bank of the Ozarks, Inc. is responsible for establishing and maintaining adequate internal control over financial reporting. 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 accounting principles generally accepted in the United States. 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 assets; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with accounting principles generally accepted in the United States, and that receipts and expenditures are made only in accordance with authorizations of management and directors; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of 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 and, even when effective, can provide only reasonable assurance with respect to financial statement preparation and presentation. 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 and procedures may deteriorate.

Management of Bank of the Ozarks, Inc., including the Chief Executive Officer and the Chief Financial Officer and Chief Accounting Officer, has assessed the Company’s internal control over financial reporting as of December 31, 2015, based on criteria for effective internal control over financial reporting described in the 2013 Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. As permitted, management excluded from its assessment the operations of the Intervest Bancshares Corporation and Bank of the Carolinas Corporation acquisitions made during 2015, which acquisitions are described in Note 2 to the Consolidated Financial Statements. The assets acquired in these acquisitions and excluded from management’s assessment on internal control over financial reporting comprised approximately 12.0% of total consolidated assets at December 31, 2015. Based on this assessment, management has concluded that the Company’s internal control over financial reporting was effective as of December 31, 2015, based on the specified criteria.

Crowe Horwath LLP, the independent registered public accounting firm that audited the Company’s Consolidated Financial Statements included in this Annual Report on Form 10-K, has issued a report on the effectiveness of the Company’s internal control over financial reporting as of December 31, 2015. This report is included in this item under the heading “Report of Independent Registered Public Accounting Firm on Internal Control Over Financial Reporting.”

Summary of Significant Accounting Policies

1. Summary of Significant Accounting Policies

Organization – Bank of the Ozarks, Inc. (the “Company”) is a bank holding company headquartered in Little Rock, Arkansas, which operates under the rules and regulations of the Board of Governors of the Federal Reserve System. The Company owns a wholly-owned state chartered bank subsidiary – Bank of the Ozarks (the “Bank”). As of December 31, 2015, the Company owns eight 100%-owned finance subsidiary business trusts including Ozark Capital Statutory Trust II (“Ozark II”), Ozark Capital Statutory Trust III (“Ozark III”), Ozark Capital Statutory Trust IV (“Ozark IV”), Ozark Capital Statutory Trust V (“Ozark V”) (collectively, the “Ozark Trusts”), and as a result of the Company’s acquisition of Intervest Bancshares Corporation (“Intervest”), Intervest Statutory Trust II (“Intervest II”), Intervest Statutory Trust III (“Intervest III”), Intervest Statutory Trust IV (“Intervest IV”) and Intervest Statutory Trust V (“Intervest V”), (collectively, the “Intervest Trusts”; and together with Ozark Trusts, the “Trusts”). Each of the Trusts was formed in connection with the issuance of certain subordinated debentures and related trust preferred securities.  At December 31, 2015, the Company also owns, indirectly through the Bank, a subsidiary engaged in the development of real estate, a subsidiary that owns private aircraft and various other entities that hold foreclosed assets or tax credits or engage in other activities. The Company and the Bank are subject to the regulation of certain federal and state agencies and undergo periodic examinations by those regulatory authorities. At December 31, 2015, the Company, through the Bank, conducted operations through 174 offices, including 81 offices in Arkansas, 28 in Georgia, 25 in North Carolina, 22 in Texas, ten in Florida, three in Alabama, two offices each in South Carolina and New York and one office in California.

Basis of presentation, use of estimates and principles of consolidation – The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“GAAP”) requires management to make estimates, assumptions and judgments that affect the amounts reported in the Consolidated Financial Statements and accompanying notes. Actual results could differ from those estimates.

The Consolidated Financial Statements include the accounts of the Company, the Bank, the real estate subsidiary and the aircraft subsidiary. In addition, subsidiaries in which the Company has majority voting interest (principally defined as owning a voting or economic interest greater than 50%) or where the Company exercises control over the operating and financial policies of the subsidiary through an operating agreement or other means are consolidated. Investments in companies in which the Company has significant influence over voting and financing decisions (principally defined as owning a voting or economic interest of 20% to 50%) and investments in limited partnerships and limited liability companies where the Company does not exercise control over the operating and financial policies are generally accounted for by the equity method of accounting. Investments in companies in which the Company has limited or no influence over voting and financing decisions (principally defined as owning a voting or economic interest less than 20%) and investments in limited partnerships and limited liability companies in which the Company’s interest is so minor such that it has virtually no influence over operating and financial policies are generally accounted for by the cost method of accounting. Significant intercompany transactions and amounts have been eliminated in consolidation.

The voting interest approach is not applicable for entities that are not controlled through voting interests or in which the equity investors do not bear the residual economic risk. In such instances, management makes a determination, based on its review of applicable GAAP, on when the assets, liabilities and activities of a variable interest entity (“VIE”) should be included in the Company’s Consolidated Financial Statements. GAAP requires a VIE to be consolidated by a company if that company is considered the primary beneficiary of the VIE’s activities. The Company has determined that the 100%-owned finance subsidiary Trusts are VIEs, but that the Company is not the primary beneficiary of the Trusts. Accordingly, the Company does not consolidate the activities of the Trusts into its financial statements, but instead reports its ownership interests in the Trusts as other assets and reports the subordinated debentures issued to the Trusts as a liability in the consolidated balance sheets. The distributions on the subordinated debentures are reported as interest expense in the accompanying consolidated statements of income.

Cash and cash equivalents – For cash flow purposes, cash and cash equivalents include cash on hand, amounts due from banks and interest earning deposits with banks.

Investment securities – Management determines the appropriate classification of investment securities at the time of purchase and reevaluates such designation as of each balance sheet date. At December 31, 2015 and 2014, the Company has classified all of its investment securities as available for sale (“AFS”).

Investment securities AFS are reported at estimated fair value, with the unrealized gains and losses determined on a specific identification basis. Such unrealized gains and losses, net of tax, are reported as a separate component of stockholders’ equity and included in other comprehensive income (loss). The Company utilizes independent third parties as its principal pricing sources for determining fair value of investment securities which are measured on a recurring basis. As a result, the Company receives estimates of fair values from at least two independent pricing sources for the majority of its individual securities within its investment portfolio. For investment securities traded in an active market, fair values are based on quoted market prices if available. If quoted market prices are not available, fair values are based on quoted market prices of comparable securities, broker quotes or comprehensive interest rate tables, pricing matrices or a combination thereof. For investment securities traded in a market that is not active, fair value is determined using unobservable inputs. Additionally, the valuation of investment securities acquired may include certain unobservable inputs. All fair value estimates received by the Company for its investment securities are reviewed and approved on a quarterly basis by the Company’s Investment Portfolio Manager and its Chief Financial Officer.

At December 31, 2015 and 2014, the Company owned stock in the Federal Home Loan Bank of Dallas (“FHLB”) and First National Banker’s Bankshares, Inc. (“FNBB”), which do not have readily determinable fair values and are carried at cost.

Declines in the fair value of investment securities below their amortized cost are reviewed at least quarterly by the Company for other-than-temporary impairment. Factors considered during such review include, among other things, the length of time and extent that fair value has been less than cost and the financial condition and near term prospects of the issuer. The Company also assesses whether it has the intent to sell the investment security or more likely than not would be required to sell the investment security before any anticipated recovery in fair value. If either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost and fair value is recognized as impairment through the income statement. For securities that do not meet the aforementioned criteria, the amount of impairment is split into (i) other-than-temporary impairment related to credit loss, which must be recognized in the income statement, and (ii) other-than-temporary impairment related to other factors, which is recognized in other comprehensive income (loss). The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis.

The fair values of the Company’s investment securities traded in both active and inactive markets can be volatile and may be influenced by a number of factors including market interest rates, prepayment speeds, discount rates, credit quality of the issuer, general market conditions including market liquidity conditions and other factors. Factors and conditions are constantly changing and fair values could be subject to material variations that may significantly impact the Company’s financial condition, results of operations and liquidity.

Interest and dividends on investment securities, including the amortization of premiums and accretion of discounts through maturity, or in the case of mortgage-backed securities, over the estimated life of the security, are included in interest income. Realized gains or losses on the sale of investment securities are recognized on the specific identification method at the time of sale and are included in non-interest income. Purchases and sales of investment securities are recorded on a trade-date basis.

Non-purchased loans and leases – Non-purchased loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at their outstanding principal balance adjusted for any charge-offs and deferred fees or costs. Interest on non-purchased loans is recognized on an accrual basis and is calculated using the simple interest method on daily balances of the principal amount outstanding. Loan origination fees and costs are generally deferred and recognized over the life of the loan as an adjustment to yield on the related loan.

Leases, all of which are non-purchased, are classified as either direct financing leases or operating leases, based on the terms of the agreement. Direct financing leases are reported as the sum of (i) total future lease payments to be received, net of unearned income, and (ii) estimated residual value of the leased property. Operating leases are recorded at the cost of the leased property, net of accumulated depreciation. Income on direct financing leases is included in interest income and is recognized on a basis that achieves a constant periodic rate of return on the outstanding investment. Income on operating leases is recognized as non-interest income on a straight-line basis over the lease term.

In the ordinary course of business, the Company has entered into off-balance sheet financial instruments consisting of commitments to extend credit and letters of credit. Such financial instruments are recorded in the financial statements when they are funded. Related fees are generally recognized when collected.

Mortgage loans held for sale are included in the Company’s non-purchased loans and leases and totaled $10.4 million and $10.9 million at December 31, 2015 and 2014, respectively. Mortgage loans held for sale are carried at the lower of cost or fair value. Gains and losses from the sales of mortgage loans are the difference between the selling price of the loan and its carrying value, net of discounts and points, and are recognized as mortgage lending income when the loan is sold to investors and servicing rights are released.

As part of its standard mortgage lending practice, the Company issues a written put option, in the form of an interest rate lock commitment (“IRLC”), such that the interest rate on the mortgage loan is established prior to funding. In addition to the IRLC, the Company enters into a forward sale commitment (“FSC”) for the sale of its mortgage loan originations to reduce its market risk and interest rate risk on such originations in process. The IRLC on mortgage loans held for sale and the FSC have been determined to be derivatives as defined by GAAP. Accordingly, the fair values of derivative assets and liabilities for the Company’s IRLC and FSC are based primarily on the fluctuation of interest rates between the date on which the particular IRLC and FSC were entered into and year-end. At December 31, 2015 and 2014, respectively, the Company’s IRLC and FSC derivative assets and corresponding derivative liabilities were not material. The notional amounts of loan commitments under both the IRLC and FSC were $15.7 million and $17.2 million at December 31, 2015 and 2014, respectively.

Purchased loans – Purchased loans are initially recorded at fair value on the date of purchase. Purchased loans that contain evidence of credit deterioration on the date of purchase are carried at the net present value of expected future proceeds. All other purchased loans are recorded at their initial fair value, adjusted for subsequent advances, pay downs, amortization or accretion of any premium or discount on purchase, charge-offs and any other adjustment to carrying value.

As provided for under GAAP, management has up to 12 months following the date of the acquisition to finalize the fair values of acquired assets and assumed liabilities. Once management has finalized the fair values of acquired assets and assumed liabilities within this 12-month period, management considers such values to be the day 1 fair values (“Day 1 Fair Values”).

At the time of acquisition of purchased loans, management individually evaluates substantially all loans acquired in the transaction. For those purchased loans without evidence of credit deterioration, management evaluates each reviewed loan using an internal grading system with a grade assigned to each loan at the date of acquisition. To the extent that any purchased loan is not specifically reviewed, such loan is assumed to have characteristics similar to the characteristics of the acquired portfolio of purchased loans. The grade for each purchased loan without evidence of credit deterioration is reviewed subsequent to the date of acquisition any time a loan is renewed or extended or at any time information becomes available to the Company that provides material insight regarding the loan’s performance, the status of the borrower or the quality or value of the underlying collateral. To the extent that current information indicates it is probable that the Company will collect all amounts according to the contractual terms thereof, such loan is not considered impaired and is not individually considered in the determination of the required allowance for loan and lease losses (“ALLL”). To the extent that current information indicates it is probable that the Company will not be able to collect all amounts according to the contractual terms thereof, such loan is considered impaired and is considered in the determination of the required level of ALLL.

In determining the Day 1 Fair Values of purchased loans without evidence of credit deterioration at the date of acquisition, management includes (i) no carry over of any previously recorded ALLL and (ii) an adjustment of the unpaid principal balance to reflect an appropriate market rate of interest, given the risk profile and grade assigned to each loan. This adjustment is accreted into earnings as a yield adjustment, using the effective yield method, over the remaining life of each loan.

Purchased loans that contain evidence of credit deterioration on the date of purchase are individually evaluated by management to determine the estimated fair value of each loan. This evaluation includes no carryover of any previously recorded ALLL. In determining the estimated fair value of purchased loans with evidence of credit deterioration, management considers a number of factors including, among other things, the remaining life of the acquired loans, estimated prepayments, estimated loss ratios, estimated value of the underlying collateral, estimated holding periods, and net present value of cash flows expected to be received.

In determining the Day 1 Fair Values of purchased loans with evidence of credit deterioration at the date of acquisition, management calculates a non-accretable difference (the credit component of the purchased loans) and an accretable difference (the yield component of the purchased loans). The non-accretable difference is the difference between the contractually required payments and the cash flows expected to be collected in accordance with management’s determination of the Day 1 Fair Values. Subsequent increases in expected cash flows will result in an adjustment to accretable yield, which will have a positive impact on interest income. Subsequent decreases in expected cash flows will generally result in a provision for loan and lease losses. Subsequent increases in expected cash flows following any previous decrease will result in a reversal of the provision for loan and lease losses to the extent of prior charges and then an adjustment to accretable yield.

The accretable difference on purchased loans with evidence of credit deterioration at the date of acquisition is the difference between the expected cash flows and the net present value of such expected cash flows. Such difference is accreted into earnings using the effective yield method over the term of the loans. In determining the net present value of the expected cash flows for purposes of establishing the Day 1 Fair Values, the Company used discount rates ranging from 6.0% to 9.5% per annum depending on the risk characteristics of each individual loan.

Management separately monitors purchased loans with evidence of credit deterioration on the date of purchase and periodically reviews such loans contained within this portfolio against the factors and assumptions used in determining the Day 1 Fair Values. A loan is reviewed (i) any time it is renewed or extended, (ii) at any other time additional information becomes available to the Company that provides material additional insight regarding the loan’s performance, the status of the borrower, or the quality or value of the underlying collateral, or (iii) in conjunction with the annual review of projected cash flows of each acquired portfolio. Management separately reviews the performance of the portfolio of purchased loans with evidence of credit deterioration at the date of acquisition on an annual basis, or more frequently to the extent that material information becomes available regarding the performance of an individual loan, to make determinations of the constituent loans’ performance and to consider whether there has been any significant change in performance since management’s initial expectations established in conjunction with the determination of the Day 1 Fair Values or since management’s most recent review of such portfolio’s performance. To the extent that a loan is performing in accordance with or exceeding management’s performance expectation established in conjunction with the determination of the Day 1 Fair Values, such loan is rated FV66, is not included in any of the credit quality ratios, is not considered to be a nonaccrual, nonperforming or impaired loan, and is not considered in the determination of the required ALLL. For any loan that is exceeding management’s performance expectation established in conjunction with the determination of Day 1 Fair Values, the accretable yield on such loan is adjusted to reflect such increased performance. To the extent that a loan’s performance has deteriorated from management’s expectation established in conjunction with the determination of the Day 1 Fair Values, such loan is rated FV88, is included in certain of the Company’s credit quality metrics, is considered an impaired loan, and is considered in the determination of the required level of ALLL; however, in accordance with GAAP, the Company continues to accrete into earnings income on such loans. Any improvement in the expected performance of such loan would result in a reversal of the provision for loan and lease losses to the extent of prior charges and then an adjustment to accretable yield.

Allowance for loan and lease losses – The ALLL is established through a provision for such losses charged against income. All or portions of loans or leases deemed to be uncollectible are charged against the ALLL when management believes that collectability of all or some portion of outstanding principal is unlikely. Subsequent recoveries, if any, of loans or leases previously charged off are credited to the ALLL.

The ALLL is maintained at a level management believes will be adequate to absorb probable incurred losses in the loan and lease portfolio. Provision to and the adequacy of the ALLL are based on evaluations of the loan and lease portfolio utilizing objective and subjective criteria. The objective criteria primarily include an internal grading system and specific allowances. In addition to the objective criteria, the Company subjectively assesses the adequacy of the ALLL and the need for additions thereto, with consideration given to the nature and mix of the portfolio, including concentrations of credit; general economic and business conditions, including national, regional and local business and economic conditions that may affect borrowers’ or lessees’ ability to pay; expectations regarding the current business cycle; trends that could affect collateral values and other relevant factors. The Company also utilizes a peer group analysis and a historical analysis to validate the overall adequacy of its ALLL. Changes in any of these criteria or the availability of new information could require adjustment of the ALLL in future periods. While a specific allowance has been calculated for impaired loans and leases and for loans and leases where the Company has otherwise determined a specific reserve is appropriate, no portion of the Company’s ALLL is restricted to any individual loan or lease or group of loans or leases, and the entire ALLL is available to absorb losses from any and all loans and leases.

The Company’s internal grading system assigns grades to all non-purchased loans and leases, except residential 1-4 family loans, consumer loans and certain other loans, with each grade being assigned an allowance allocation percentage. The grade for each graded individual loan or lease is determined by the account officer and other approving officers at the time the loan or lease is made and changed from time to time to reflect an ongoing assessment of loan or lease risk. Grades are reviewed on specific loans and leases from time to time by senior management and as part of the Company’s internal loan review process. The risk elements considered by management in its determination of the appropriate grade for individual loans and leases include the following, among others: (1) for non-farm/non-residential, multifamily residential, and agricultural real estate loans, the debt service coverage ratio (income from the property in excess of operating expenses compared to loan repayment requirements), operating results of the owner in the case of owner-occupied properties, the loan-to-value ratio, the age, condition, value, nature and marketability of the collateral and the specific risks and volatility of income, property value and operating results typical of properties of that type; (2) for construction and land development loans, the perceived feasibility of the project including the ability to sell developed lots or improvements constructed for resale or ability to lease property constructed for lease, the quality and nature of contracts for presale or preleasing, if any, experience and ability of the developer and loan-to-cost and loan-to-value ratios; (3) for commercial and industrial loans and leases, the operating results of the commercial, industrial or professional enterprise, the borrower’s or lessee’s business, professional and financial ability and expertise, the specific risks and volatility of income and operating results typical for businesses in the applicable industry, the age, condition, value, nature and marketability of collateral and, for certain loans, the marketability of such loans in any secondary market; and (4) for non-real estate agricultural loans and leases, the operating results, experience and ability of the borrower or lessee, historical and expected market conditions and the age, condition, value, nature and marketability of collateral. In addition, for each category the Company considers secondary sources of income and the financial strength of the borrower or lessee and any guarantors.

Residential 1-4 family, consumer loans and certain other loans are assigned an allowance allocation percentage based on past due status.

Allowance allocation percentages for the various risk grades and past due categories for residential 1-4 family, consumer loans and certain other loans are determined by management and are adjusted periodically. In determining these allowance allocation percentages, management considers, among other factors, historical loss percentages over various time periods and a variety of subjective criteria.

For purchased loans, management segregates this portfolio into loans that contain evidence of credit deterioration on the date of acquisition and loans that do not contain evidence of credit deterioration on the date of acquisition. Purchased loans with evidence of credit deterioration are regularly monitored and are periodically reviewed by management. To the extent that a loan’s performance has deteriorated from management’s expectation established in conjunction with the determination of the Day 1 Fair Values, such loan is considered in the determination of the required level of ALLL. To the extent that a revised loss estimate exceeds the loss estimate established in the determination of Day 1 Fair Values, such determination will result in an allowance allocation or a partial or full charge-off.

All other purchased loans are graded by management at the time of purchase. The grade on these purchased loans is reviewed regularly as part of the ongoing assessment of such loans. To the extent that current information indicates it is probable that the Company will not be able to collect all amounts according to the contractual terms thereof, such loan is considered in the determination of the required level of ALLL and may result in an allowance allocation or a partial or full charge-off.

At December 31, 2015, the Company established an ALLL totaling $1.2 million for its purchased loan portfolio.  Such ALLL was based on the Company’s historical charge-off analysis of its purchased loan portfolio and reflects management’s estimate of probable incurred losses in the purchased loan portfolio that had not previously been charged off.  At December 31, 2014, the Company had no ALLL for its purchased loan portfolio as the Company had determined that all losses had been charged off on purchased loans where management had determined it was probable that the Company would be unable to collect all amounts according to the contractual terms thereof (for purchased loans without evidence of credit deterioration at date of acquisition) or whose performance had deteriorated from management’s expectations established in conjunction with the determination of the Day 1 Fair Values (for purchased loans with evidence of credit deterioration at date of acquisition).

The accrual of interest on non-purchased loans and leases and purchased loans without evidence of credit deterioration at the date of acquisition is discontinued when, in management’s opinion, the borrower or lessee may be unable to meet payments as they become due. The Company generally places a loan or lease, excluding purchased loans with evidence of credit deterioration on the date of acquisition, on nonaccrual status when such loan or lease is (i) deemed impaired or (ii) 90 days or more past due, or earlier when doubt exists as to the ultimate collection of payments. The Company may continue to accrue interest on certain loans or leases contractually past due 90 days or more if such loans or leases are both well secured and in the process of collection. At the time a loan or lease is placed on nonaccrual status, interest previously accrued but uncollected is reversed and charged against interest income. Nonaccrual loans and leases are generally returned to accrual status when payments are less than 90 days past due and the Company reasonably expects to collect all payments. If a loan or lease is determined to be uncollectible, the portion of the principal determined to be uncollectible will be charged against the ALLL. Loans for which the terms have been modified and for which (i) the borrower is experiencing financial difficulties and (ii) a concession has been granted to the borrower by the Company are considered troubled debt restructurings (“TDRs”) and are included in impaired loans and leases. Income on nonaccrual loans or leases, including impaired loans and leases but excluding certain TDRs which continue to accrue interest, is recognized on a cash basis when and if actually collected.

All loans and leases deemed to be impaired are evaluated individually. The Company considers a loan or lease, excluding purchased loans with evidence of credit deterioration at the date of acquisition, to be impaired when based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms thereof. The Company considers a purchased loan with evidence of credit deterioration at the date of acquisition to be impaired once a decrease in expected cash flows or other deterioration in the loan’s expected performance, subsequent to the determination of the Day 1 Fair Values, results in an allowance allocation, a partial or full charge-off or in a provision for loan and lease losses. Most of the Company’s nonaccrual loans and leases, excluding purchased loans with evidence of credit deterioration at the date of acquisition, and all TDRs are considered impaired. The majority of the Company’s impaired loans and leases are dependent upon collateral for repayment. For such loans and leases, impairment is measured by comparing collateral value, net of holding and selling costs, to the current investment in the loan or lease. For all other impaired loans and leases, the Company compares estimated discounted cash flows to the current investment in the loan or lease. To the extent that the Company’s current investment in a particular loan or lease exceeds its estimated net collateral value or its estimated discounted cash flows, the impaired amount is specifically considered in the determination of the ALLL or is charged off as a reduction of the ALLL. The Company’s practice is to charge off any estimated loss as soon as management is able to identify and reasonably quantify such potential loss. Accordingly, only a small portion of the Company’s ALLL is needed for potential losses on nonperforming loans.

The Company also maintains an allowance for certain non-purchased loans and leases not considered impaired where (i) the customer is continuing to make regular payments, although payments may be past due, (ii) there is a reasonable basis to believe the customer may continue to make regular payments, although there is also an elevated risk that the customer may default, and (iii) the collateral or other repayment sources are likely to be insufficient to recover the current investment in the loan or lease if a default occurs. The Company evaluates such loans and leases to determine if an allowance is needed for these loans and leases. For the purpose of calculating the amount of such allowance, management assumes that (i) no further regular payments occur and (ii) all sums recovered will come from liquidation of collateral and collection efforts from other payment sources. To the extent that the Company’s current investment in a particular loan or lease evaluated for the need for such allowance exceeds its net collateral value, such excess is considered allocated allowance for purposes of the determination of the ALLL.

The Company also includes specific ALLL allocations for qualitative factors including, (i) general economic and business conditions, (ii) trends that could affect collateral values and (iii) expectations regarding the current business cycle. The Company may also consider other qualitative factors in future periods for additional ALLL allocations.

Changes in the criteria used in this evaluation or the availability of new information could cause the ALLL to be increased or decreased in future periods. In addition, bank regulatory agencies, as part of their examination process, may require adjustments to the ALLL based on their judgment and estimates.

Premises and equipment – Premises and equipment are reported at cost less accumulated depreciation and amortization. Depreciation and amortization are computed on a straight-line basis over the estimated useful lives of the related assets. Depreciable lives for the major classes of assets are generally 20 to 45 years for buildings and 3 to 25 years for furniture, fixtures, equipment and certain building improvements. Leasehold improvements are amortized over the shorter of the asset’s estimated useful life or the term of the lease. Accelerated depreciation methods are used for income tax purposes. Maintenance and repair charges are expensed as incurred.

Foreclosed assets – Repossessed personal properties and real estate acquired through or in lieu of foreclosure, excluding purchased foreclosed assets, are initially recorded at the lesser of current principal investment or fair value less estimated cost to sell (generally 8% to 10%) at the date of repossession or foreclosure. Purchased foreclosed assets are initially recorded at Day 1 Fair Values. In estimating such Day 1 Fair Values, management considered a number of factors including, among others, appraised value, estimated selling price, estimated holding periods and net present value (calculated using discount rates ranging from 8.0% to 9.5% per annum) of cash flows expected to be received.

Valuations of all foreclosed assets are periodically reviewed by management with the carrying value of such assets adjusted through non-interest expense to the then estimated fair value, generally based on third party appraisals, broker price opinions or other valuations of the property, net of estimated selling costs, if lower, until disposition. Gains and losses from the sale of such repossessions and real estate acquired through or in lieu of foreclosure are recorded in non-interest income, and expenses to maintain the properties are included in non-interest expense.

Income taxes – The Company utilizes the asset and liability method in accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based upon the difference between the values of the assets and liabilities as reflected in the financial statements and their related tax basis using enacted tax rates in effect for the year or years in which the differences are expected to be recovered or settled. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes.

As a result of recording, at fair value, acquired assets and assumed liabilities pursuant to business combinations, differences in amounts reported for financial statement purposes and their related basis for federal and state income tax purposes are created. Such differences are recorded as deferred tax assets and liabilities using enacted tax rates in effect for the year or years in which the differences are expected to be recovered or settled. Business combination transactions may result in the acquisition of net operating loss carryforwards and other assets with built-in losses, the realization of which are subject to limitations pursuant to section 382 (“section 382 limitation”) of the Internal Revenue Code (“IRC”). In determining the section 382 limitation associated with a business combination, management must make a number of estimates and assumptions regarding the ability to utilize acquired net operating loss carryforwards and the expected timing of future recoveries or settlements of acquired assets with built-in losses. To the extent that information available as of the date of acquisition results in a determination by management that some portion of acquired net operating loss carryforwards cannot be utilized or assets with built-in losses are expected to be settled or recovered in future periods in which the ability to realize the benefits will be subject to section 382 limitation, a deferred tax asset valuation allowance is established for the estimated amount of the deferred tax assets subject to the section 382 limitation. To the extent that information becomes available, during the first 12 months following the consummation of a business combination transaction, that results in changes in management’s initial estimates and assumptions regarding the expected utilization of acquired net operating loss carryforwards or the expected settlement or recovery of acquired assets with built-in losses subject to section 382 limitation, an increase or decrease of the deferred tax asset valuation allowance will be recorded as an adjustment to bargain purchase gain or goodwill. To the extent that such information becomes available 12 months or more after the consummation of a business combination transaction, or additional information becomes available during the first 12 months as a result of changes in circumstances since the date of the consummation of a business combination transaction, an increase or decrease of the deferred tax asset valuation allowance will be recorded as an adjustment to deferred income tax expense (benefit).

The Company recognizes a tax position as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that has a greater than 50% likelihood of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded.

The Company files consolidated tax returns. The Bank and the other consolidated entities provide for income taxes on a separate return basis and remit to the Company amounts determined to be currently payable. The Company recognizes interest related to income tax matters as interest income or expense, and penalties related to income tax matters are recognized as non-interest expense. The Company is no longer subject to income tax examinations by U.S. federal tax authorities for years prior to 2012.

Bank owned life insurance (“BOLI”) – BOLI consists of life insurance purchased by the Company on (i) a qualifying group of officers with the Company designated as owner and beneficiary of the policies and (ii) one of the Company’s executive officers with the Company designated as owner and both the Company and the executive officer designated as beneficiaries of the policies. The earnings on BOLI policies help to offset a portion of employee benefit costs or to offset a portion of the costs of a supplemental executive retirement plan for one of the Company’s executive officers. BOLI is carried at the policies’ realizable cash surrender values with changes in cash surrender values and death benefits received in excess of cash surrender values reported in non-interest income.

Intangible assets – Intangible assets consist of goodwill, bank charter costs and core deposit intangibles. Goodwill represents the excess purchase price over the fair value of net assets acquired in business acquisitions. The Company had goodwill of $125.4 million and $78.7 million at December 31, 2015 and 2014, respectively. The Company performed its annual impairment test of goodwill as of September 30, 2015. This test indicated no impairment of the Company’s goodwill.

Bank charter costs represent costs paid to acquire a Texas bank charter and are being amortized over 20 years. Bank charter costs totaled $239,000 at both December 31, 2015 and 2014, less accumulated amortization of $144,000 and $132,000 at December 31, 2015 and 2014, respectively.

Core deposit intangibles represent premiums paid for deposits acquired via acquisition and are being amortized over three to seven years. Core deposit intangibles totaled $41.5 million and $36.5 million at December 31, 2015 and 2014, respectively, less accumulated amortization of $14.7 million and $9.7 million at December 31, 2015 and 2014, respectively.

The aggregate amount of amortization expense for the Company’s core deposit and bank charter intangibles is expected to be $6.2 million in 2016, $5.9 million in 2017, $5.9 million in 2018, $5.5 million in 2019 and $3.0 million in 2020.

Stock-based compensation – The Company has a non-qualified employee stock option plan, a non-employee director stock plan and an employee restricted stock plan, each of which is described more fully in Note 16. The Company measures the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. Such cost is recognized over the vesting period of the award.

Earnings per common share – Earnings per common share are computed using the two-class method. Basic earnings per common share are computed by dividing net income available to common stockholders by the weighted-average number of common shares outstanding during the applicable period. Diluted earnings per common share are computed by dividing net income available to common stockholders by the weighted-average number of common shares outstanding after consideration of the dilutive effect, if any, of the Company’s common stock options using the treasury stock method. The Company has determined that its outstanding non-vested stock awards granted under its restricted stock plan are participating securities.

Segment disclosures – The Company operates in only one segment – community banking. Accordingly, there is no requirement to report segment information in the Company’s Consolidated Financial Statements. No revenues are derived from foreign countries and no single external customer comprises more than 10% of the Company’s revenues.

Recent accounting pronouncements – In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers.” ASU 2014-09 provides guidance that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. In August 2015, the FASB issued ASU 2015-14, which defers the effective date of this standard to annual and interim periods beginning after December 15, 2017; however, early adoption is permitted for annual and interim reporting periods beginning after December 15, 2016. The Company is currently evaluating the impact, if any, ASU 2014-09 will have on its financial position, results of operations, and its financial statement disclosures.

In June 2014, the FASB issued ASU 2014-11 “Transfers and Servicing (Topic 860).” ASU 2014-11 amends the accounting guidance for repo-to-maturity transactions and requires such transactions to be accounted for as secured borrowings. In addition, ASU 2014-11 requires enhanced disclosures related to the collateral pledged, maturity and risk associated with repurchase agreements. The Company adopted the provision of ASU 2014-11 beginning April 1, 2015. The adoption of ASU 2014-11 did not have a significant impact on the Company’s financial position or results of operations but did require additional disclosures about the Company’s repurchase agreements.

In January 2015, the FASB issued ASU 2015-01, “Income Statement – Extraordinary and Unusual Items (Subtopic 225-20) – Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items.” ASU 2015-01 eliminates from GAAP the concept of extraordinary items, which, among other things, required an entity to segregate extraordinary items considered to be unusual and infrequent from the results of ordinary operations and show the item separately in the income statement, net of tax, after income from continuing operations. ASU 2015-01 is effective for interim and annual periods beginning after December 15, 2015. ASU 2015-01 is not expected to have a significant impact on the Company’s financial position, results of operations, or its financial statement disclosures.

In February 2015, the FASB issued ASU 2015-02, “Consolidation (Topic 810): Amendments to the Consolidation Analysis” which amends the consolidation requirements of ASU 810 by changing the consolidation analysis required under GAAP. The revised guidance amends the consolidation analysis based on certain fee arrangements or relationships to the reporting entity and, for limited partnerships, requires entities to consider the limited partner’s rights relative to the general partner. ASU 2015-02 is effective for annual and interim periods beginning after December 15, 2015. ASU 2015-02 is not expected to have a significant impact on the Company’s financial position, results of operations, or its financial statement disclosures.

In April 2015, the FASB issued ASU 2015-03, “Interest – Imputation of Interest (Subtopic 835-30) – Simplifying the Presentation of Debt Issuance Costs.” ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in ASU 2015-03. In August 2015, the FASB issued ASU 2015-15 to clarify the Securities and Exchange Commission (“SEC”) staff’s position on presenting and measuring debt issue costs related to line-of-credit arrangements.  ASU 2015-03 and ASU 2015-15 are effective for interim and annual periods beginning after December 15, 2015. ASU 2015-03 and ASU 2015-15 are not expected to have a significant impact on the Company’s financial position, results of operations, or its financial statement disclosures.

In September 2015, the FASB issued ASU 2015-16 “Simplifying the Accounting for Measurement-Period Adjustments.”  ASU 2015-16 requires entities to recognize measurement period adjustments during the reporting period in which the adjustments are determined.  The income effects, if any, of a measurement period adjustment are cumulative and are to be reported in the period in which the adjustment to a provisional amount is determined.  Also, ASU 2015-16 requires presentation on the face of the income statement or in the notes, the effect of the measurement period adjustment as if the adjustment had been recognized at acquisition date.  ASU 2015-16 is effective for fiscal periods beginning after December 15, 2016 and should be applied prospectively to measurement period adjustments that occur after the effective date.

In January 2016, FASB issued ASU 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities.” ASU 2016-01 revises the accounting for the classification and measurement of investments in equity securities and revises the presentation of certain fair value changes for financial liabilities measured at fair value.  For equity securities, the guidance in ASU 2016-01 requires equity investments to be measured at fair value with changes in fair value recognized in net income.  For financial liabilities that are measured at fair value in accordance with the fair value option, the guidance requires presenting, in other comprehensive income, the change in fair value that relates to a change in instrument-specific credit risk. ASU 2016-01 also eliminates the disclosure assumptions used to estimate fair value for financial instruments measured at amortized cost and requires disclosure of an exit price notion in determining the fair value of financial instruments measured at amortized cost.  ASU 2016-01 is effective for interim and annual periods beginning after December 15, 2017.  The Company is evaluating the impact, if any, that ASU 2016-01 will have on its financial position, results of operations, and its financial statement disclosures.

Proposed Accounting Pronouncements – In December 2012, the FASB announced a project related to the impairment of financial instruments in an effort to provide new guidance that would significantly change how entities measure and recognize credit impairment for certain financial assets.  While completion of the project and related guidance is still pending, it is anticipated that new guidance will replace the current incurred loss model that is utilized in estimating the ALLL with a model that requires management to estimate all contractual cash flows that are not expected to be collected over the life of the loan. The FASB describes this revised model as the current expected credit loss (“CECL”) model and believes the CECL model will result in more timely recognition of credit losses since the CECL model incorporates expected credit losses versus incurred credit losses.  The proposed scope of FASB’s CECL model would include loans, held-to-maturity debt instruments, lease receivables, loan commitments and financial guarantees that are not accounted for at fair value.  The final issuance date and the implementation date of the CECL guidance is currently pending, and the Company will continue to monitor FASB’s progress on this project.  

Reclassifications and recasts – Certain reclassifications of prior years’ amounts have been made to conform with the 2015 financial statements presentation. These reclassifications had no impact on prior years’ net income, as previously reported. During the second and fourth quarter of 2015, the Company revised its initial estimates regarding the expected recovery of certain acquired loans and deferred tax assets in its February 10, 2015 acquisition of Intervest. As a result, certain amounts previously reported in the Company’s 2015 interim consolidated financial statements have been recast.

Acquisitions

2. Acquisitions

Bank of the Carolinas

On August 5, 2015, the Company completed its acquisition of Bank of the Carolinas Corporation (“BCAR”) and its wholly-owned subsidiary Bank of the Carolinas for an aggregate of 1,447,620 shares of its common stock (plus cash in lieu of fractional shares) in a transaction valued at approximately $65.4 million. The acquisition of BCAR expands the Company’s operations in North Carolina by adding eight retail banking offices, including one office each in Advance, Asheboro, Concord, Harrisburg, Landis, Lexington, Mocksville and Winston-Salem. As a result of the BCAR acquisition, the Company acquired total assets with an estimated fair value of $351.3 million, total loans with an estimated fair value of $266.2 million and total deposits with an estimated fair value of $288.9 million.  Goodwill of $4.8 million, which is the excess of the merger consideration over the estimated fair value of net assets acquired, was recorded in the BCAR acquisition and is the result of expected operational synergies, expansion of banking services in the Piedmont Triad region of North Carolina and other factors.  This goodwill is not expected to be deductible for tax purposes.

Intervest Bancshares Corporation

On February 10, 2015, the Company completed its acquisition of Intervest and its wholly-owned bank subsidiary Intervest National Bank, for an aggregate of 6,637,243 shares of its common stock (plus cash in lieu of fractional shares) in a transaction valued at approximately $238.5 million. The acquisition of Intervest provided the Company with a retail banking office in New York City and expanded its service area in Florida by adding five retail banking offices in Clearwater, Florida and one retail banking office in South Pasadena, Florida. During the third quarter of 2015, the Company closed one of the acquired retail banking offices in Clearwater, Florida.  During the fourth quarter of 2015, the Company eliminated the New York lending operations acquired in the Intervest acquisition.  Also, during the second and fourth quarters of 2015, management revised its initial estimates and assumptions regarding the recovery of certain acquired loans and acquired deferred tax assets.  Because such revision occurred during the first 12 months following the date of acquisition and was not the result of a change in circumstances, management has decreased the goodwill recorded in the Intervest transaction by $4.9 million to reflect this change in estimate.  

The following table provides a summary of the assets acquired and liabilities assumed as recorded by Intervest, the fair value adjustments necessary to adjust those acquired assets and assumed liabilities to estimated fair value, the recast adjustments described above and the estimates of the resultant fair values of those assets and liabilities as recorded by the Company. As provided for under GAAP, management has up to 12 months following the date of acquisition to finalize the fair values of the acquired assets and assumed liabilities. Once management has finalized the fair values of acquired assets and assumed liabilities within this 12-month period, management considers such values to be the Day 1 Fair Values.  The fair values shown in the following table have been determined by management to be the Day 1 Fair Values.

The acquisition of Summit expanded the Company’s service area in Central, South and Western Arkansas by adding 23 retail banking locations and one loan production office in nine Arkansas counties. Subsequent to the acquisition, the Company closed the acquired loan production office and eight retail banking offices, including six retail banking offices that were acquired from Summit, in markets where the Company had excess branches as a result of the Summit acquisition.  Goodwill of $73.4 million, which is the excess of the merger consideration over the fair value of net assets acquired, was recorded in the Summit acquisition and is the result of expected operational synergies and other factors.  This goodwill is not expected to be deductible for tax purposes.  

Bancshares, Inc.

In evaluating the Company’s unrealized loss positions for other-than-temporary impairment for its investment securities portfolio, management considers the credit quality of the issuer, the nature and cause of the unrealized loss, the severity and duration of the impairments and other factors. At December 31, 2015 and 2014, management determined the unrealized losses were the result of fluctuations in interest rates and did not reflect deteriorations of the credit quality of the investments. Accordingly, management believes that all of its unrealized losses on investment securities are temporary in nature. The Company does not have the intent to sell these investment securities and more likely than not, would not be required to sell these investment securities before fair value recovers to amortized cost.

The following table is a maturity distribution of investment securities AFS as of December 31, 2015.

	Amortized Cost		Estimated Fair Value
	(Dollars in thousands)

Due after ten years		300,834		309,912
Total	$	589,490	$	602,348

For purposes of this maturity distribution, all investment securities are shown based on their contractual maturity date, except (i) FHLB and FNBB stock and the CRA qualified investment funds which have no contractual maturity date are shown in the longest maturity category and (ii) U.S. Government agency securities and municipal housing authority securities backed by residential mortgages are allocated among various maturities based on an estimated repayment schedule utilizing Bloomberg median prepayment speeds and interest rate levels at December 31, 2015. Expected maturities will differ from contractual maturities because issuers may have the right to call or prepay obligations with or without call or prepayment penalties.

As of December 31, 2015 and 2014, the Company had identified purchased loans where management had determined it was probable that the Company would be unable to collect all amounts according to the contractual terms thereof (for purchased loans without evidence of credit deterioration at date of acquisition) or the expected performance of such loans had deteriorated from management’s performance expectations established in conjunction with the determination of the Day 1 Fair Values or since management’s most recent review of such portfolio’s performance (for purchased loans with evidence of credit deterioration at date of acquisition). As a result the Company recorded net charge-offs totaling $2.5 million during 2015 and $3.2 million during 2014 for such loans. The Company also recorded $2.5 million during 2015 and $3.2 million during 2014 of provision for loan and lease losses to cover these charge-offs. Also, the Company recorded $1.2 million of additional provision in 2015 (none in 2014) to absorb probable incurred losses in its purchased loan portfolio that had not previously been charged off.  Additionally, the Company transferred certain of these purchased loans to foreclosed assets. As a result of these actions, the Company had $8.1 million of impaired purchased loans at December 31, 2015 and $14.0 million of impaired purchased loans at December 31, 2014.

(1) The Company does not risk rate its residential 1-4 family loans, its consumer loans, and certain “other” loans. However, for purposes of the above table, the Company considers such loans to be (i) satisfactory – if they are performing and less than 30 days past due, (ii) watch – if they are performing and 30 to 89 days past due or (iii) substandard – if they are nonperforming or 90 days or more past due.

The following categories of credit quality indicators are used by the Company.

Satisfactory – Loans and leases in this category are considered to be a satisfactory credit risk and are generally considered to be collectible in full.

Moderate – Loans and leases in this category are considered to be a marginally satisfactory credit risk and are generally considered to be collectible in full.

Watch – Loans and leases in this category are presently protected from apparent loss, however weaknesses exist which could cause future impairment of repayment of principal or interest.

Substandard – Loans and leases in this category are characterized by deterioration in quality exhibited by a number of weaknesses requiring corrective action and posing risk of some loss.

The following table is an aging analysis of past due non-purchased loans and leases as of the dates indicated.

The fair value adjustment of $4.5 million is being amortized, using a level-yield methodology over the estimated holding period of approximately eight years, as an increase in interest expense of the subordinated debentures owed to the Intervest Trusts. In addition to the subordinated debentures of the Intervest Trusts, the Company also acquired $1.7 million of trust common equity issued by the Intervest Trusts.

The trust preferred securities issued by Intervest Trust II and the related subordinated debentures bear interest, adjustable quarterly, at 90-day LIBOR plus 2.95% and contain a final maturity of September 17, 2033. The trust preferred securities issued by Intervest Trust III and the related subordinated debentures bear interest, adjustable quarterly, at 90-day LIBOR plus 2.79% and contain a final maturity of March 17, 2034. The trust preferred securities issued by Intervest Trust IV and the related subordinated debentures bear interest, adjustable quarterly, at 90-day LIBOR plus 2.40% and contain a final maturity of September 20, 2034. The trust preferred securities issued by Intervest Trust V and the related subordinated debentures bear interest, adjustable quarterly, at 90-day LIBOR plus 1.65% and contain a final maturity of December 15, 2036.

At December 31, 2015, the Company had an aggregate of $121.7 million of subordinated debentures outstanding (with an aggregate carrying value of $117.7 million) and had an asset of $3.7 million representing its investment in the common equity issued by the Trusts. The sole assets of the Trusts are the adjustable rate debentures and the liabilities of the Trusts are the trust preferred securities. At December 31, 2015 and 2014, the Trusts had aggregate common equity of $3.7 million and $1.9 million, respectively, and did not have any restricted net assets. The Company has, through various contractual arrangements or by operation of law, fully and unconditionally guaranteed all obligations of the Trusts with respect to the trust preferred securities. Additionally, there are no restrictions on the ability of the Trusts to transfer funds to the Company in the form of cash dividends, loans or advances. The Company has the option to defer interest payments on the subordinated debentures from time to time for a period not to exceed five consecutive years. These trust preferred securities generally mature at or near the 30th anniversary date of each issuance. However, the trust preferred securities and related subordinated debentures may be prepaid at par, subject to regulatory approval.

Employee Benefit Plans

15. Employee Benefit Plans

The Company maintains a qualified retirement plan (the “401(k) Plan”) with a salary deferral feature designed to qualify under Section 401 of the IRC. The 401(k) Plan permits employees of the Company to defer a portion of their compensation in accordance with the provisions of Section 401(k) of the IRC. During 2012, the Company amended the 401(k) Plan to make it a Safe-Harbor Cost or Deferred Arrangement (“Safe-Harbor CODA”) effective January 1, 2013. As a result, (i) certain key employees are eligible to make salary deferrals into the 401(k) Plan beginning January 1, 2013, (ii) the 401(k) Plan is no longer subject to any provisions of the average deferral percentage test described in IRC section 401(k)(3) or the average contribution percentage test described in IRC section 401(m)(2), (iii) the basic matching contribution is (a) 100% of the amount of the employee’s deferrals that do not exceed 3% of the employee’s compensation for the year plus (b) 50% of the amount of the employee’s elective deferrals that exceed 3% but do not exceed 5% of the employee’s compensation for the year, and (iv) all employer matching contributions made under the provisions of the Safe-Harbor CODA are non-forfeitable. Certain other statutory limitations with respect to the Company’s contribution under the 401(k) Plan also apply. Matching contributions made by the Company prior to the 401(k) Plan becoming a Safe-Harbor CODA vest over six years and are held in trust until distributed pursuant to the terms of the 401(k) Plan.

Contributions to the 401(k) Plan are invested in accordance with participant elections among certain investment options. Distributions from participant accounts are not permitted before age 65, except in the event of death, permanent disability, certain financial hardships or termination of employment. The Company made matching cash contributions to the 401(k) Plan during 2015, 2014 and 2013 of $2.7 million, $2.3 million and $1.8 million, respectively.

The Company also maintains the Bank of the Ozarks, Inc. Deferred Compensation Plan (the “Plan”), which is an unfunded deferred compensation arrangement for the group of employees designated as key employees, including certain of the Company’s executive officers. Under the terms of the Plan, eligible participants may elect to defer a portion of their compensation. Such deferred compensation is distributable in lump sum or specified installments upon separation from service with the Company or upon other specified events as defined in the Plan. Prior to 2013, the Company had the ability to make a contribution to each participant’s account, limited to one half of the first 6% of compensation deferred by the participant and subject to certain other limitations. Effective January 1, 2013, the Plan was amended such that the Company no longer makes any contribution to the Plan for the benefit of each participant or otherwise. Amounts deferred under the Plan are invested in certain approved investments (excluding securities of the Company or its affiliates). At both December 31, 2015 and 2014, the Company had Plan assets, along with an equal amount of liabilities, totaling $4.2 million, recorded on the accompanying consolidated balance sheet.

Effective May 4, 2010, the Company established a Supplemental Executive Retirement Plan (“SERP”) and certain other benefit arrangements for its Chairman and Chief Executive Officer. Pursuant to the SERP, this officer is entitled to receive 180 equal monthly payments of $32,197, or $386,360 annually, commencing at the later of obtaining age 70 or separation from service. If separation from service occurs prior to age 70, such benefit will be at a reduced amount. The costs of such benefits, assuming a retirement date at age 70, will be fully accrued by the Company at such retirement date. During 2015, 2014 and 2013, respectively, the Company accrued $223,000, $200,000 and $180,000 for the future benefits payable under the SERP. The SERP is an unfunded plan and is considered a general contractual obligation of the Company.

Stock-Based Compensation

16. Stock-Based Compensation

The Company has a nonqualified stock option plan for certain key employees and officers of the Company. This plan provides for the granting of nonqualified options to purchase shares of common stock in the Company. No option may be granted under this plan for less than the fair market value of the common stock, defined by the plan as the average of the highest reported asked price and the lowest reported bid price, on the date of the grant. The benefits or amounts that may be received by or allocated to any particular officer or employee of the Company under this plan will be determined in the sole discretion of the Company’s board of directors or its personnel and compensation committee. All employee options outstanding at December 31, 2015 were issued with a vesting period of three years and expire seven years after issuance. At December 31, 2015 there were 1,319,549 shares available for future grants under this plan.

During 2015, the Company adopted the Bank of the Ozarks, Inc. Non-Employee Director Stock Plan (the “Director Plan”) that provides for awards of common stock to eligible non-employee directors. The Director Plan grants to each director who is not otherwise an employee of the Company, or any subsidiary, shares of common stock on the day of his or her election as director of the Company at each annual shareholders meeting, or any special meeting called for the purpose of electing a director or directors of the Company, and upon appointment for the first time as director of the Company. The number of shares of common stock to be awarded will be the equivalent of $25,000 worth of shares of common stock based on the average of the highest reported asked price and lowest reported bid price on the grant date. The common stock awarded under this plan is fully vested on the grant date. The aggregate number of shares of common stock which may be issued as awards under this plan will not exceed 50,000 shares, subject to certain adjustments. During 2015, the Company issued 7,657 shares of common stock and incurred $0.3 million in stock-based compensation expense related to common stock awards issued under the Director Plan.

Prior to the adoption of the Director Plan, the Company had a nonqualified stock option plan for non-employee directors. No options were granted under this plan during 2015. All options previously granted under this plan were exercisable immediately and expire ten years after issuance.

The following table summarizes stock option activity for both the employee and non-employee director stock option plans for the year ended December 31, 2015.

	Options			Weighted- Average Exercise Price/Share		Weighted- Average Remaining Contractual Life (in years)		Aggregate Intrinsic Value (in thousands)

Fully vested and expected to vest at December 31, 2015(2)		1,819,370		$	33.29		5.5	$	31,245	(1)

(1) Based on closing price of $49.46 per share on December 31, 2015.

(2) At December 31, 2015 the Company estimates that options to purchase 215,106 shares of the Company’s common stock will not vest and will be forfeited prior to their vesting date.

Intrinsic value for stock options is defined as the amount by which the current market price of the underlying stock exceeds the exercise price. For those stock options where the exercise price exceeds the current market price of the underlying stock, the intrinsic value is zero. The total intrinsic value of options exercised during 2015, 2014 and 2013 was $12.5 million, $10.0 million and $7.7 million, respectively.

Options to purchase 659,181 shares, 616,250 shares and 526,000 shares, respectively, were granted during 2015, 2014 and 2013 with a weighted-average grant date fair value of $14.00, $7.04 and $5.61, respectively. The fair value for each option grant is estimated on the date of grant using the Black-Scholes option pricing model.

The following table is a summary of the weighted-average assumptions used in the Black-Scholes option pricing model for the years indicated.

	Year Ended December 31,
	2015			2014			2013
Risk-free interest rate		1.69	%		1.62	%		1.30	%
Expected dividend yield		1.19	%		1.49	%		1.85	%
Expected stock volatility		31.0	%		24.1	%		30.2	%
Expected life (years)		5.0			5.0			5.0

The Company uses the U.S. Treasury yield curve in effect at the time of the grant to determine the risk-free interest rate. The expected dividend yield is estimated using the current annual dividend level and recent stock price of the Company’s common stock at the date of grant. Expected stock volatility is based on historical volatilities of the Company’s common stock. The expected life of the options is calculated based on the “simplified” method as provided for under SEC Staff Accounting Bulletin No. 110.

The total fair value of options to purchase shares of the Company’s common stock that vested during 2015, 2014 and 2013 was $2.0 million, $1.5 million and $1.2 million, respectively. Stock-based compensation expense for stock options included in non-interest expense was $2.6 million, $2.1 million and $1.7 million for 2015, 2014 and 2013, respectively. Total unrecognized compensation cost related to non-vested stock option grants was $9.7 million at December 31, 2015 and is expected to be recognized over a weighted-average period of 2.5 years.

The Company has a restricted stock and incentive plan that permits issuance of up to 1,600,000 shares of restricted stock or restricted stock units. All officers and employees of the Company are eligible to receive awards under the restricted stock and incentive plan. The benefits or amounts that may be received by or allocated to any particular officer or employee of the Company under the restricted stock and incentive plan will be determined in the sole discretion of the Company’s board of directors or its personnel and compensation committee. Shares of common stock issued under the restricted stock and incentive plan may be shares of original issuance, shares held in treasury or shares that have been reacquired by the Company. At December 31, 2015 there were 576,325 shares available for future grants under this plan.

The following table summarizes non-vested restricted stock activity for the year ended December 31, 2015.

	Shares
Outstanding – January 1, 2015		444,700
Granted		245,300
Forfeited		(41,325	)
Earned and issued		(213,200	)
Outstanding – December 31, 2015		435,475
Weighted-average grant date fair value	$	29.87

Restricted stock awards of 245,300 shares were granted during 2015 with a weighted-average grant date fair value of $34.39. No restricted stock awards were granted during 2014. The fair value of the restricted stock awards is amortized to compensation expense over the vesting period (generally three years) and is based on the market price of the Company’s common stock at the date of grant multiplied by the number of shares granted that are expected to vest. Stock-based compensation expense for restricted stock included in non-interest expense was $5.2 million, $3.5 million and $2.8 million for 2015, 2014 and 2013, respectively. Unrecognized compensation expense for nonvested restricted stock awards was $6.8 million at December 31, 2015 and is expected to be recognized over a weighted-average period of 1.8 years.

On January 13, 2016 the Company’s personnel and compensation committee approved the issuance of restricted stock awards for 212,907 shares of restricted common stock that vest on January 13, 2019. Total compensation expense for the restricted stock awards is expected to be approximately $9.1 million and is expected to be recognized ratably over the three-year vesting period.

Commitments and Contingencies

17. Commitments and Contingencies

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 primarily include standby letters of credit and commitments to extend credit.

Outstanding standby letters of credit are contingent commitments issued by the Company generally to guarantee the performance of a customer in third party borrowing arrangements. The terms of the letters of credit are generally for a period of one year. The maximum amount of future payments the Company could be required to make under these letters of credit at December 31, 2015 and 2014 is $16.5 million and $4.5 million, respectively. The Company holds collateral to support letters of credit when deemed necessary. The total of collateralized commitments at December 31, 2015 and 2014 was $15.9 million and $4.3 million, respectively.

The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit is represented by the contractual amount of those instruments. The Company has the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments.

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 these commitments may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the counterparty. The type of collateral held varies but may include accounts receivable, inventory, property, plant and equipment, and other real or personal property.

At December 31, 2015, the Company had outstanding commitments to extend credit, excluding mortgage interest rate lock commitments, totaling $5.8 billion. The following table shows the contractual maturities of outstanding commitments to extend credit at December 31, 2015.

Banking And Thrift [Abstract]

Regulatory Matters

19. Regulatory Matters

The Company is subject to various regulatory capital requirements administered by federal and state banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s financial condition and results of operations. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company must meet specific capital guidelines that involve quantitative measures of the Company’s assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. The Company’s capital amounts and classification are also subject to qualitative judgments by the regulators about component risk weightings and other factors.

The FDIC and other federal banking regulators revised the risk-based capital requirements applicable to bank holding companies and insured depository institutions, including the Company and the Bank, to make them consistent with agreements that were reached by the Basel Committee on Banking Supervision (“Basel III”) and certain provisions of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Basel III Rules”). The Basel III Rules became effective for the Company and the Bank on January 1, 2015 (subject to a phase-in period for certain provisions). The Basel III Rules require the maintenance of minimum amounts and ratios (set forth in the following table) of common equity tier 1 capital, tier 1 capital and total capital (as defined in the regulations) to risk-weighted assets (as defined), and of tier 1 capital to adjusted quarterly average assets (as defined).

Under the Basel III Rules, common equity tier 1 capital consists of common stock and paid-in capital (net of treasury stock) and retained earnings. Common equity tier 1 capital is reduced by goodwill, certain intangible assets, net of associated deferred tax liabilities, deferred tax assets that arise from tax credit and net operating loss carryforwards, net of any valuation allowance, and certain other items as specified by the Basel III Rules.

Tier 1 capital includes common equity tier 1 capital and certain additional tier 1 items as provided under the Basel III Rules. The tier 1 capital for the Company consists of common equity tier 1 capital and $118 million of trust preferred securities issued by the Trusts. The Basel III Rules include certain provisions that would require trust preferred securities to be phased out of qualifying tier 1 capital. Currently, the Company’s trust preferred securities are grandfathered under the Basel III Rules and will continue to be included as tier 1 capital. However, should the Company exceed $15 billion in total assets, the grandfather provisions applicable to its trust preferred securities would no longer apply and such trust preferred securities would no longer be included as tier 1 capital, but would continue to be included as total capital. The common equity tier 1 capital and the tier 1 capital are the same for the Bank.

Basel III Rules allow for insured depository institutions to make a one-time election not to include most elements of accumulated other comprehensive income in regulatory capital and instead effectively use the existing treatment under the general risk-based capital rules. The Company and Bank made this opt-out election to avoid significant variations in the level of capital depending upon the impact of interest rate fluctuations on the fair value of its investments securities portfolio.

Total capital includes tier 1 capital and tier 2 capital. Tier 2 capital includes, among other things, the allowable portion of the ALLL and any trust preferred securities that are excluded from tier 1 capital.

The Basel III Rules also changed the risk-weights of assets in an effort to better reflect credit risk and other risk exposures. These include a 150% risk weight (up from 100%) for certain high volatility commercial real estate acquisition, development and construction loans and the unsecured portion of non-residential mortgage loans that are 90 days past due or otherwise on nonaccrual status; a 20% (up from 0%) credit conversion factor for the unused portion of a commitment with an original maturity of one year or less that is not unconditionally cancellable; a 250% risk weight (up from 100%) for mortgage servicing rights and deferred tax assets that are not deducted from capital; and increased risk weights (from 0% to up to 600%) for equity exposures.

The common equity tier 1 capital, tier 1 capital and total capital ratios are calculated by dividing the respective capital amounts by risk-weighted assets. The leverage ratio is calculated by dividing tier 1 capital by adjusted quarterly average total assets.

The Basel III Rules limit capital distributions and certain discretionary bonus payments if the banking organization does not hold a “capital conservation buffer” consisting of 2.5% of common equity tier 1 capital, tier 1 capital and total capital to risk-weighted assets in addition to the amount necessary to meet minimum risk-based capital requirements. The capital conservation buffer will be phased in beginning January 1, 2016, at 0.625% of risk-weighted assets, increasing each year by that amount until fully implemented at 2.5% on January 1, 2019. When fully phased in on January 1, 2019, the Basel III Rules will require the Company and Bank to maintain (i) a minimum ratio of common equity tier 1 capital to risk-weighted assets of at least 4.5%, plus a 2.5% capital conservation buffer, which effectively results in a minimum ratio of 7.0% upon full implementation, (ii) a minimum ratio of tier 1 capital to risk-weighted assets of at least 6.0%, plus a 2.5% capital conservation buffer, which effectively results in a minimum ratio of 8.50% upon full implementation, (iii) a minimum ratio of total capital to risk-weighted assets of at least 8.0%, plus a 2.5% capital conservation buffer, which effectively results in a minimum ratio of 10.5% upon full implementation and (iv) a minimum leverage ratio of at least 4.0%.

Prior to January 1, 2015, federal and state regulatory agencies required the Company and the Bank to maintain minimum Tier 1 and total capital to risk-weighted assets of 4.0% and 8.0%, respectively, and Tier 1 capital to average quarterly assets (Tier 1 leverage ratio) of at least 3.0%. Tier 1 capital consisted of common equity, retained earnings, certain types of preferred stock, qualifying minority interest and trust preferred securities, subject to limitations, and excluded goodwill and various intangible assets. Total capital included Tier 1 capital, any amounts of trust preferred securities excluded from Tier 1 capital, and the lesser of the ALLL or 1.25% of risk-weighted assets.

The following table presents actual and required capital ratios as of December 31, 2015 for the Company and the Bank under the Basel III Rules. The minimum required capital amounts presented include the minimum required capital levels as of December 31, 2015 based on the current phase-in provisions of the Basel III Rules and the minimum required capital levels as of January 1, 2019 when the Basel III Rules have been fully phased-in. Capital levels required to be considered well capitalized are based upon prompt corrective action regulations, as amended to reflect the changes under the Basel III Rules.

As of December 31, 2015 and 2014, the most recent notification from the regulators categorized the Company and the Bank as well capitalized under the regulatory framework for prompt corrective action. There are no conditions or events since that notification that management believes have changed the Company’s or the Bank’s category.

The state bank commissioner’s approval is required before the Bank can declare and pay any dividend of 75% or more of the net profits of the Bank after all taxes for the current year plus 75% of the retained net profits for the immediately preceding year. At December 31, 2015 and 2014, respectively, $117.8 million and $18.8 million were available for payment of dividends by the Bank without the approval of regulatory authorities.

Under FRB regulation, the Bank is also limited as to the amount it may loan to its affiliates, including the Company, and such loans must be collateralized by specific types of collateral. The maximum amount available for loan from the Bank to the Company is limited to 10% of the Bank’s capital and surplus or approximately $155 million and $93 million, respectively, at December 31, 2015 and 2014.

Fair Value Measurements

20. Fair Value Measurements

The Company measures certain of its assets and liabilities on a fair value basis using various valuation techniques and assumptions, depending on the nature of the asset or liability. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Additionally, fair value is used either annually or on a non-recurring basis to evaluate certain assets and liabilities for impairment or for disclosure purposes. At December 31, 2015 and 2014, the Company had no liabilities that were accounted for at fair value.

The Company applies the following fair value hierarchy.

Level 1 – Quoted prices for identical instruments in active markets.

Level 2 – Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable.

Level 3 – Instruments whose inputs are unobservable.

The following table sets forth the Company’s assets, as of the date indicated, that are accounted for at fair value.

(1) The Company utilizes valuation techniques consistent with the market, cost, and income approaches, or a combination thereof in determining fair value.

The following methods and assumptions are used to estimate the fair value of the Company’s assets that are accounted for at fair value.

Investment securities – The Company utilizes independent third parties as its principal sources for determining fair value of investment securities which are measured on a recurring basis. As a result, the Company receives estimates of fair values from at least two independent pricing sources for the majority of its individual securities within its investment portfolio. For investment securities traded in an active market, the fair values are obtained from independent pricing services and are based on quoted market prices if available. If quoted market prices are not available, fair values are based on market prices for comparable securities, broker quotes or comprehensive interest rate tables, pricing matrices or a combination thereof. For investment securities traded in a market that is not active, fair value is determined using unobservable inputs. All fair value estimates of the Company’s investment securities are reviewed and approved on a quarterly basis by the Company’s Investment Portfolio Manager and its Chief Financial Officer.

The Company has determined that certain of its investment securities had a limited to non-existent trading market at December 31, 2015 and 2014. As a result, the Company considers these investments as Level 3 in the fair value hierarchy. Specifically the fair values of certain obligations of state and political subdivisions consisting of certain unrated private placement bonds (the “private placement bonds”) in the amount of $18.5 million and $19.4 million at December 31, 2015 and 2014, respectively, were calculated using Level 3 hierarchy inputs and assumptions as the trading market for such securities was determined to be “not active.” This determination was based on the limited number of trades or, in certain cases, the existence of no reported trades for the private placement bonds. The private placement bonds are generally prepayable at par value at the option of the issuer. As a result, management believes the private placement bonds should be valued at the lower of (i) the matrix pricing provided by the Company’s third party pricing services for comparable unrated municipal securities or (ii) par value. At December 31, 2015 and 2014, the third party pricing matrices valued the Company’s total portfolio of private placement bonds at $18.5 million and $19.4 million, respectively, which was equal to the par value of the private placement bonds at December 31, 2015 and 2014. Accordingly, at December 31, 2015 and 2014 the Company reported the private placement bonds at $18.5 million and $19.4 million, respectively.

Impaired non-purchased loans and leases – Fair values are measured on a non-recurring basis based on the underlying collateral value of the impaired loan or lease, reduced for holding and selling costs, or the estimated discounted cash flows for such loan or lease. The Company has reduced the carrying value of its impaired non-purchased loans and leases (all of which are included in nonaccrual loans and leases) by $7.8 million and $5.9 million, respectively, to the estimated fair value of $9.3 million and $19.5 million, respectively, for such loans and leases at December 31, 2015 and 2014. These adjustments to reduce the carrying value of impaired non-purchased loans and leases to estimated fair value at December 31, 2015 and 2014 consisted of $6.5 million and $4.8 million, respectively, of partial or full charge-offs and $1.3 million and $1.1 million, respectively, of specific loan and lease loss allocations.

Impaired purchased loans – Impaired purchased loans are measured at fair value on a non-recurring basis. At December 31, 2015 and 2014, the Company had identified purchased loans where management had determined it was probable that the Company would be unable to collect all amounts according to the contractual terms thereof (for purchased loans without evidence of credit deterioration at date of acquisition) or the expected performance of such loans had deteriorated from management’s performance expectations established in conjunction with the determination of the Day 1 Fair Values or since management’s most recent review of such portfolio’s performance (for purchased loans with evidence of credit deterioration at date of acquisition). As a result the Company recorded net charge-offs, totaling $2.5 million during 2015 and $3.2 million during 2014 for such loans. The Company recorded $2.5 million during 2015 and $3.2 million during 2014 of provision for loan and lease losses to cover these charge-offs. Also, the Company recorded $1.2 million of additional provision in 2015 (none in 2014) for loan and lease losses to absorb probable incurred losses in its purchased loan portfolio that had not previously been charged off. Additionally, the Company transferred certain of these purchased loans to foreclosed assets. As a result of these actions, the Company had $8.1 million of impaired purchased loans at December 31, 2015 and $14.0 million of impaired purchased loans at December 31, 2014.

Foreclosed assets – Repossessed personal properties and real estate acquired through or in lieu of foreclosure, excluding purchased foreclosed assets, are initially recorded at the lesser of current principal investment or fair value less estimated cost to sell (generally 8% to 10%) at the date of repossession or foreclosure. Purchased foreclosed assets are initially recorded at Day 1 Fair Values. In estimating such Day 1 Fair Values, management considered a number of factors including, among others, appraised value, estimated selling price, estimated holding periods and net present value (calculated using discount rates ranging from 8.0% to 9.5% per annum) of cash flows expected to be received.

Valuations of all foreclosed assets are periodically reviewed by management with the carrying value of such assets adjusted through non-interest expense to the then estimated fair value, generally based on third party appraisals, broker price opinions or other valuations of the property, net of estimated selling costs, if lower, until disposition.

The following table presents additional information for the periods indicated about assets measured at fair value on a recurring basis and for which the Company has utilized Level 3 inputs to determine fair value.

Fair Value of Financial Instruments

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments

21. Fair Value of Financial Instruments

The following methods and assumptions were used to estimate the fair value of financial instruments.

Cash and due from banks – For these short-term instruments, the carrying amount is a reasonable estimate of fair value.

Investment securities – The Company utilizes independent third parties as its principal sources for determining fair value of investment securities which are measured on a recurring basis. As a result, the Company receives estimates of fair values from at least two independent pricing sources for the majority of its individual securities within its investment portfolio. For investment securities traded in an active market, the fair values are obtained from independent pricing services and are based on quoted market prices if available. If quoted market prices are not available, fair values are based on market prices for comparable securities, broker quotes, comprehensive interest rate tables, pricing matrices or a combination thereof. For investment securities traded in a market that is not active, fair value is determined using unobservable inputs. All fair value estimates of the Company’s investment securities are reviewed and approved on a quarterly basis by the Company’s Investment Portfolio Manager and its Chief Financial Officer. The Company’s investments in the common stock of the FHLB and FNBB of $23.5 million and $14.2 million at December 31, 2015 and 2014 do not have readily determinable fair values and are carried at cost.

Loans and leases – The fair value of loans and leases, including purchased loans, is estimated by discounting the future cash flows using the current rate at which similar loans or leases would be made to borrowers or lessees with similar credit ratings and for the same remaining maturities.

Deposit liabilities – The fair value of demand deposits, savings accounts, money market deposits and other transaction accounts is the amount payable on demand at the reporting date. The fair value of fixed maturity time deposits is estimated using the rate currently available for deposits of similar remaining maturities.

Repurchase agreements – For these short-term instruments, the carrying amount is a reasonable estimate of fair value.

Other borrowed funds – For these short-term instruments, the carrying amount is a reasonable estimate of fair value. The fair value of long-term instruments is estimated based on the current rates available to the Company for borrowings with similar terms and remaining maturities.

Subordinated debentures – The fair values of these instruments are based primarily upon discounted cash flows using rates for securities with similar terms and remaining maturities.

Off-balance sheet instruments – The fair values of commercial loan commitments and letters of credit are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements. The fair values of commercial loan commitments and letters of credit were not material at December 31, 2015 and 2014.

The fair values of certain of these instruments were calculated by discounting expected cash flows, which contain numerous uncertainties and involve significant judgments by management. Fair value is the estimated amount at which financial assets or liabilities could be exchanged in a current transaction between willing parties other than in a forced or liquidation sale. Because no market exists for certain of these financial instruments and because management does not intend to sell these financial instruments, the Company does not know whether the fair values shown below represent values at which the respective financial instruments could be sold individually or in the aggregate.

The following table presents the carrying amounts and estimated fair values as of the dates indicated and the fair value hierarchy of the Company’s financial instruments.

Dec. 31, 2015

Accounting Policies [Abstract]

Organization

Organization – Bank of the Ozarks, Inc. (the “Company”) is a bank holding company headquartered in Little Rock, Arkansas, which operates under the rules and regulations of the Board of Governors of the Federal Reserve System. The Company owns a wholly-owned state chartered bank subsidiary – Bank of the Ozarks (the “Bank”). As of December 31, 2015, the Company owns eight 100%-owned finance subsidiary business trusts including Ozark Capital Statutory Trust II (“Ozark II”), Ozark Capital Statutory Trust III (“Ozark III”), Ozark Capital Statutory Trust IV (“Ozark IV”), Ozark Capital Statutory Trust V (“Ozark V”) (collectively, the “Ozark Trusts”), and as a result of the Company’s acquisition of Intervest Bancshares Corporation (“Intervest”), Intervest Statutory Trust II (“Intervest II”), Intervest Statutory Trust III (“Intervest III”), Intervest Statutory Trust IV (“Intervest IV”) and Intervest Statutory Trust V (“Intervest V”), (collectively, the “Intervest Trusts”; and together with Ozark Trusts, the “Trusts”). Each of the Trusts was formed in connection with the issuance of certain subordinated debentures and related trust preferred securities.  At December 31, 2015, the Company also owns, indirectly through the Bank, a subsidiary engaged in the development of real estate, a subsidiary that owns private aircraft and various other entities that hold foreclosed assets or tax credits or engage in other activities. The Company and the Bank are subject to the regulation of certain federal and state agencies and undergo periodic examinations by those regulatory authorities. At December 31, 2015, the Company, through the Bank, conducted operations through 174 offices, including 81 offices in Arkansas, 28 in Georgia, 25 in North Carolina, 22 in Texas, ten in Florida, three in Alabama, two offices each in South Carolina and New York and one office in California.

Basis of Presentation, Use of Estimates and Principles of Consolidation

Basis of presentation, use of estimates and principles of consolidation – The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“GAAP”) requires management to make estimates, assumptions and judgments that affect the amounts reported in the Consolidated Financial Statements and accompanying notes. Actual results could differ from those estimates.

The Consolidated Financial Statements include the accounts of the Company, the Bank, the real estate subsidiary and the aircraft subsidiary. In addition, subsidiaries in which the Company has majority voting interest (principally defined as owning a voting or economic interest greater than 50%) or where the Company exercises control over the operating and financial policies of the subsidiary through an operating agreement or other means are consolidated. Investments in companies in which the Company has significant influence over voting and financing decisions (principally defined as owning a voting or economic interest of 20% to 50%) and investments in limited partnerships and limited liability companies where the Company does not exercise control over the operating and financial policies are generally accounted for by the equity method of accounting. Investments in companies in which the Company has limited or no influence over voting and financing decisions (principally defined as owning a voting or economic interest less than 20%) and investments in limited partnerships and limited liability companies in which the Company’s interest is so minor such that it has virtually no influence over operating and financial policies are generally accounted for by the cost method of accounting. Significant intercompany transactions and amounts have been eliminated in consolidation.

The voting interest approach is not applicable for entities that are not controlled through voting interests or in which the equity investors do not bear the residual economic risk. In such instances, management makes a determination, based on its review of applicable GAAP, on when the assets, liabilities and activities of a variable interest entity (“VIE”) should be included in the Company’s Consolidated Financial Statements. GAAP requires a VIE to be consolidated by a company if that company is considered the primary beneficiary of the VIE’s activities. The Company has determined that the 100%-owned finance subsidiary Trusts are VIEs, but that the Company is not the primary beneficiary of the Trusts. Accordingly, the Company does not consolidate the activities of the Trusts into its financial statements, but instead reports its ownership interests in the Trusts as other assets and reports the subordinated debentures issued to the Trusts as a liability in the consolidated balance sheets. The distributions on the subordinated debentures are reported as interest expense in the accompanying consolidated statements of income.

Cash and Cash Equivalents

Cash and cash equivalents – For cash flow purposes, cash and cash equivalents include cash on hand, amounts due from banks and interest earning deposits with banks.

Investment Securities

Investment securities – Management determines the appropriate classification of investment securities at the time of purchase and reevaluates such designation as of each balance sheet date. At December 31, 2015 and 2014, the Company has classified all of its investment securities as available for sale (“AFS”).

Investment securities AFS are reported at estimated fair value, with the unrealized gains and losses determined on a specific identification basis. Such unrealized gains and losses, net of tax, are reported as a separate component of stockholders’ equity and included in other comprehensive income (loss). The Company utilizes independent third parties as its principal pricing sources for determining fair value of investment securities which are measured on a recurring basis. As a result, the Company receives estimates of fair values from at least two independent pricing sources for the majority of its individual securities within its investment portfolio. For investment securities traded in an active market, fair values are based on quoted market prices if available. If quoted market prices are not available, fair values are based on quoted market prices of comparable securities, broker quotes or comprehensive interest rate tables, pricing matrices or a combination thereof. For investment securities traded in a market that is not active, fair value is determined using unobservable inputs. Additionally, the valuation of investment securities acquired may include certain unobservable inputs. All fair value estimates received by the Company for its investment securities are reviewed and approved on a quarterly basis by the Company’s Investment Portfolio Manager and its Chief Financial Officer.

At December 31, 2015 and 2014, the Company owned stock in the Federal Home Loan Bank of Dallas (“FHLB”) and First National Banker’s Bankshares, Inc. (“FNBB”), which do not have readily determinable fair values and are carried at cost.

Declines in the fair value of investment securities below their amortized cost are reviewed at least quarterly by the Company for other-than-temporary impairment. Factors considered during such review include, among other things, the length of time and extent that fair value has been less than cost and the financial condition and near term prospects of the issuer. The Company also assesses whether it has the intent to sell the investment security or more likely than not would be required to sell the investment security before any anticipated recovery in fair value. If either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost and fair value is recognized as impairment through the income statement. For securities that do not meet the aforementioned criteria, the amount of impairment is split into (i) other-than-temporary impairment related to credit loss, which must be recognized in the income statement, and (ii) other-than-temporary impairment related to other factors, which is recognized in other comprehensive income (loss). The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis.

The fair values of the Company’s investment securities traded in both active and inactive markets can be volatile and may be influenced by a number of factors including market interest rates, prepayment speeds, discount rates, credit quality of the issuer, general market conditions including market liquidity conditions and other factors. Factors and conditions are constantly changing and fair values could be subject to material variations that may significantly impact the Company’s financial condition, results of operations and liquidity.

Interest and dividends on investment securities, including the amortization of premiums and accretion of discounts through maturity, or in the case of mortgage-backed securities, over the estimated life of the security, are included in interest income. Realized gains or losses on the sale of investment securities are recognized on the specific identification method at the time of sale and are included in non-interest income. Purchases and sales of investment securities are recorded on a trade-date basis.

Non-Purchased Loans and Leases

Non-purchased loans and leases – Non-purchased loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at their outstanding principal balance adjusted for any charge-offs and deferred fees or costs. Interest on non-purchased loans is recognized on an accrual basis and is calculated using the simple interest method on daily balances of the principal amount outstanding. Loan origination fees and costs are generally deferred and recognized over the life of the loan as an adjustment to yield on the related loan.

Leases, all of which are non-purchased, are classified as either direct financing leases or operating leases, based on the terms of the agreement. Direct financing leases are reported as the sum of (i) total future lease payments to be received, net of unearned income, and (ii) estimated residual value of the leased property. Operating leases are recorded at the cost of the leased property, net of accumulated depreciation. Income on direct financing leases is included in interest income and is recognized on a basis that achieves a constant periodic rate of return on the outstanding investment. Income on operating leases is recognized as non-interest income on a straight-line basis over the lease term.

In the ordinary course of business, the Company has entered into off-balance sheet financial instruments consisting of commitments to extend credit and letters of credit. Such financial instruments are recorded in the financial statements when they are funded. Related fees are generally recognized when collected.

Mortgage loans held for sale are included in the Company’s non-purchased loans and leases and totaled $10.4 million and $10.9 million at December 31, 2015 and 2014, respectively. Mortgage loans held for sale are carried at the lower of cost or fair value. Gains and losses from the sales of mortgage loans are the difference between the selling price of the loan and its carrying value, net of discounts and points, and are recognized as mortgage lending income when the loan is sold to investors and servicing rights are released.

As part of its standard mortgage lending practice, the Company issues a written put option, in the form of an interest rate lock commitment (“IRLC”), such that the interest rate on the mortgage loan is established prior to funding. In addition to the IRLC, the Company enters into a forward sale commitment (“FSC”) for the sale of its mortgage loan originations to reduce its market risk and interest rate risk on such originations in process. The IRLC on mortgage loans held for sale and the FSC have been determined to be derivatives as defined by GAAP. Accordingly, the fair values of derivative assets and liabilities for the Company’s IRLC and FSC are based primarily on the fluctuation of interest rates between the date on which the particular IRLC and FSC were entered into and year-end. At December 31, 2015 and 2014, respectively, the Company’s IRLC and FSC derivative assets and corresponding derivative liabilities were not material. The notional amounts of loan commitments under both the IRLC and FSC were $15.7 million and $17.2 million at December 31, 2015 and 2014, respectively.

Purchased Loans

Purchased loans – Purchased loans are initially recorded at fair value on the date of purchase. Purchased loans that contain evidence of credit deterioration on the date of purchase are carried at the net present value of expected future proceeds. All other purchased loans are recorded at their initial fair value, adjusted for subsequent advances, pay downs, amortization or accretion of any premium or discount on purchase, charge-offs and any other adjustment to carrying value.

As provided for under GAAP, management has up to 12 months following the date of the acquisition to finalize the fair values of acquired assets and assumed liabilities. Once management has finalized the fair values of acquired assets and assumed liabilities within this 12-month period, management considers such values to be the day 1 fair values (“Day 1 Fair Values”).

At the time of acquisition of purchased loans, management individually evaluates substantially all loans acquired in the transaction. For those purchased loans without evidence of credit deterioration, management evaluates each reviewed loan using an internal grading system with a grade assigned to each loan at the date of acquisition. To the extent that any purchased loan is not specifically reviewed, such loan is assumed to have characteristics similar to the characteristics of the acquired portfolio of purchased loans. The grade for each purchased loan without evidence of credit deterioration is reviewed subsequent to the date of acquisition any time a loan is renewed or extended or at any time information becomes available to the Company that provides material insight regarding the loan’s performance, the status of the borrower or the quality or value of the underlying collateral. To the extent that current information indicates it is probable that the Company will collect all amounts according to the contractual terms thereof, such loan is not considered impaired and is not individually considered in the determination of the required allowance for loan and lease losses (“ALLL”). To the extent that current information indicates it is probable that the Company will not be able to collect all amounts according to the contractual terms thereof, such loan is considered impaired and is considered in the determination of the required level of ALLL.

In determining the Day 1 Fair Values of purchased loans without evidence of credit deterioration at the date of acquisition, management includes (i) no carry over of any previously recorded ALLL and (ii) an adjustment of the unpaid principal balance to reflect an appropriate market rate of interest, given the risk profile and grade assigned to each loan. This adjustment is accreted into earnings as a yield adjustment, using the effective yield method, over the remaining life of each loan.

Purchased loans that contain evidence of credit deterioration on the date of purchase are individually evaluated by management to determine the estimated fair value of each loan. This evaluation includes no carryover of any previously recorded ALLL. In determining the estimated fair value of purchased loans with evidence of credit deterioration, management considers a number of factors including, among other things, the remaining life of the acquired loans, estimated prepayments, estimated loss ratios, estimated value of the underlying collateral, estimated holding periods, and net present value of cash flows expected to be received.

In determining the Day 1 Fair Values of purchased loans with evidence of credit deterioration at the date of acquisition, management calculates a non-accretable difference (the credit component of the purchased loans) and an accretable difference (the yield component of the purchased loans). The non-accretable difference is the difference between the contractually required payments and the cash flows expected to be collected in accordance with management’s determination of the Day 1 Fair Values. Subsequent increases in expected cash flows will result in an adjustment to accretable yield, which will have a positive impact on interest income. Subsequent decreases in expected cash flows will generally result in a provision for loan and lease losses. Subsequent increases in expected cash flows following any previous decrease will result in a reversal of the provision for loan and lease losses to the extent of prior charges and then an adjustment to accretable yield.

The accretable difference on purchased loans with evidence of credit deterioration at the date of acquisition is the difference between the expected cash flows and the net present value of such expected cash flows. Such difference is accreted into earnings using the effective yield method over the term of the loans. In determining the net present value of the expected cash flows for purposes of establishing the Day 1 Fair Values, the Company used discount rates ranging from 6.0% to 9.5% per annum depending on the risk characteristics of each individual loan.

Management separately monitors purchased loans with evidence of credit deterioration on the date of purchase and periodically reviews such loans contained within this portfolio against the factors and assumptions used in determining the Day 1 Fair Values. A loan is reviewed (i) any time it is renewed or extended, (ii) at any other time additional information becomes available to the Company that provides material additional insight regarding the loan’s performance, the status of the borrower, or the quality or value of the underlying collateral, or (iii) in conjunction with the annual review of projected cash flows of each acquired portfolio. Management separately reviews the performance of the portfolio of purchased loans with evidence of credit deterioration at the date of acquisition on an annual basis, or more frequently to the extent that material information becomes available regarding the performance of an individual loan, to make determinations of the constituent loans’ performance and to consider whether there has been any significant change in performance since management’s initial expectations established in conjunction with the determination of the Day 1 Fair Values or since management’s most recent review of such portfolio’s performance. To the extent that a loan is performing in accordance with or exceeding management’s performance expectation established in conjunction with the determination of the Day 1 Fair Values, such loan is rated FV66, is not included in any of the credit quality ratios, is not considered to be a nonaccrual, nonperforming or impaired loan, and is not considered in the determination of the required ALLL. For any loan that is exceeding management’s performance expectation established in conjunction with the determination of Day 1 Fair Values, the accretable yield on such loan is adjusted to reflect such increased performance. To the extent that a loan’s performance has deteriorated from management’s expectation established in conjunction with the determination of the Day 1 Fair Values, such loan is rated FV88, is included in certain of the Company’s credit quality metrics, is considered an impaired loan, and is considered in the determination of the required level of ALLL; however, in accordance with GAAP, the Company continues to accrete into earnings income on such loans. Any improvement in the expected performance of such loan would result in a reversal of the provision for loan and lease losses to the extent of prior charges and then an adjustment to accretable yield.

Allowance for Loan and Lease Losses

Allowance for loan and lease losses – The ALLL is established through a provision for such losses charged against income. All or portions of loans or leases deemed to be uncollectible are charged against the ALLL when management believes that collectability of all or some portion of outstanding principal is unlikely. Subsequent recoveries, if any, of loans or leases previously charged off are credited to the ALLL.

The ALLL is maintained at a level management believes will be adequate to absorb probable incurred losses in the loan and lease portfolio. Provision to and the adequacy of the ALLL are based on evaluations of the loan and lease portfolio utilizing objective and subjective criteria. The objective criteria primarily include an internal grading system and specific allowances. In addition to the objective criteria, the Company subjectively assesses the adequacy of the ALLL and the need for additions thereto, with consideration given to the nature and mix of the portfolio, including concentrations of credit; general economic and business conditions, including national, regional and local business and economic conditions that may affect borrowers’ or lessees’ ability to pay; expectations regarding the current business cycle; trends that could affect collateral values and other relevant factors. The Company also utilizes a peer group analysis and a historical analysis to validate the overall adequacy of its ALLL. Changes in any of these criteria or the availability of new information could require adjustment of the ALLL in future periods. While a specific allowance has been calculated for impaired loans and leases and for loans and leases where the Company has otherwise determined a specific reserve is appropriate, no portion of the Company’s ALLL is restricted to any individual loan or lease or group of loans or leases, and the entire ALLL is available to absorb losses from any and all loans and leases.

The Company’s internal grading system assigns grades to all non-purchased loans and leases, except residential 1-4 family loans, consumer loans and certain other loans, with each grade being assigned an allowance allocation percentage. The grade for each graded individual loan or lease is determined by the account officer and other approving officers at the time the loan or lease is made and changed from time to time to reflect an ongoing assessment of loan or lease risk. Grades are reviewed on specific loans and leases from time to time by senior management and as part of the Company’s internal loan review process. The risk elements considered by management in its determination of the appropriate grade for individual loans and leases include the following, among others: (1) for non-farm/non-residential, multifamily residential, and agricultural real estate loans, the debt service coverage ratio (income from the property in excess of operating expenses compared to loan repayment requirements), operating results of the owner in the case of owner-occupied properties, the loan-to-value ratio, the age, condition, value, nature and marketability of the collateral and the specific risks and volatility of income, property value and operating results typical of properties of that type; (2) for construction and land development loans, the perceived feasibility of the project including the ability to sell developed lots or improvements constructed for resale or ability to lease property constructed for lease, the quality and nature of contracts for presale or preleasing, if any, experience and ability of the developer and loan-to-cost and loan-to-value ratios; (3) for commercial and industrial loans and leases, the operating results of the commercial, industrial or professional enterprise, the borrower’s or lessee’s business, professional and financial ability and expertise, the specific risks and volatility of income and operating results typical for businesses in the applicable industry, the age, condition, value, nature and marketability of collateral and, for certain loans, the marketability of such loans in any secondary market; and (4) for non-real estate agricultural loans and leases, the operating results, experience and ability of the borrower or lessee, historical and expected market conditions and the age, condition, value, nature and marketability of collateral. In addition, for each category the Company considers secondary sources of income and the financial strength of the borrower or lessee and any guarantors.

Residential 1-4 family, consumer loans and certain other loans are assigned an allowance allocation percentage based on past due status.

Allowance allocation percentages for the various risk grades and past due categories for residential 1-4 family, consumer loans and certain other loans are determined by management and are adjusted periodically. In determining these allowance allocation percentages, management considers, among other factors, historical loss percentages over various time periods and a variety of subjective criteria.

For purchased loans, management segregates this portfolio into loans that contain evidence of credit deterioration on the date of acquisition and loans that do not contain evidence of credit deterioration on the date of acquisition. Purchased loans with evidence of credit deterioration are regularly monitored and are periodically reviewed by management. To the extent that a loan’s performance has deteriorated from management’s expectation established in conjunction with the determination of the Day 1 Fair Values, such loan is considered in the determination of the required level of ALLL. To the extent that a revised loss estimate exceeds the loss estimate established in the determination of Day 1 Fair Values, such determination will result in an allowance allocation or a partial or full charge-off.

All other purchased loans are graded by management at the time of purchase. The grade on these purchased loans is reviewed regularly as part of the ongoing assessment of such loans. To the extent that current information indicates it is probable that the Company will not be able to collect all amounts according to the contractual terms thereof, such loan is considered in the determination of the required level of ALLL and may result in an allowance allocation or a partial or full charge-off.

At December 31, 2015, the Company established an ALLL totaling $1.2 million for its purchased loan portfolio.  Such ALLL was based on the Company’s historical charge-off analysis of its purchased loan portfolio and reflects management’s estimate of probable incurred losses in the purchased loan portfolio that had not previously been charged off.  At December 31, 2014, the Company had no ALLL for its purchased loan portfolio as the Company had determined that all losses had been charged off on purchased loans where management had determined it was probable that the Company would be unable to collect all amounts according to the contractual terms thereof (for purchased loans without evidence of credit deterioration at date of acquisition) or whose performance had deteriorated from management’s expectations established in conjunction with the determination of the Day 1 Fair Values (for purchased loans with evidence of credit deterioration at date of acquisition).

The accrual of interest on non-purchased loans and leases and purchased loans without evidence of credit deterioration at the date of acquisition is discontinued when, in management’s opinion, the borrower or lessee may be unable to meet payments as they become due. The Company generally places a loan or lease, excluding purchased loans with evidence of credit deterioration on the date of acquisition, on nonaccrual status when such loan or lease is (i) deemed impaired or (ii) 90 days or more past due, or earlier when doubt exists as to the ultimate collection of payments. The Company may continue to accrue interest on certain loans or leases contractually past due 90 days or more if such loans or leases are both well secured and in the process of collection. At the time a loan or lease is placed on nonaccrual status, interest previously accrued but uncollected is reversed and charged against interest income. Nonaccrual loans and leases are generally returned to accrual status when payments are less than 90 days past due and the Company reasonably expects to collect all payments. If a loan or lease is determined to be uncollectible, the portion of the principal determined to be uncollectible will be charged against the ALLL. Loans for which the terms have been modified and for which (i) the borrower is experiencing financial difficulties and (ii) a concession has been granted to the borrower by the Company are considered troubled debt restructurings (“TDRs”) and are included in impaired loans and leases. Income on nonaccrual loans or leases, including impaired loans and leases but excluding certain TDRs which continue to accrue interest, is recognized on a cash basis when and if actually collected.

All loans and leases deemed to be impaired are evaluated individually. The Company considers a loan or lease, excluding purchased loans with evidence of credit deterioration at the date of acquisition, to be impaired when based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms thereof. The Company considers a purchased loan with evidence of credit deterioration at the date of acquisition to be impaired once a decrease in expected cash flows or other deterioration in the loan’s expected performance, subsequent to the determination of the Day 1 Fair Values, results in an allowance allocation, a partial or full charge-off or in a provision for loan and lease losses. Most of the Company’s nonaccrual loans and leases, excluding purchased loans with evidence of credit deterioration at the date of acquisition, and all TDRs are considered impaired. The majority of the Company’s impaired loans and leases are dependent upon collateral for repayment. For such loans and leases, impairment is measured by comparing collateral value, net of holding and selling costs, to the current investment in the loan or lease. For all other impaired loans and leases, the Company compares estimated discounted cash flows to the current investment in the loan or lease. To the extent that the Company’s current investment in a particular loan or lease exceeds its estimated net collateral value or its estimated discounted cash flows, the impaired amount is specifically considered in the determination of the ALLL or is charged off as a reduction of the ALLL. The Company’s practice is to charge off any estimated loss as soon as management is able to identify and reasonably quantify such potential loss. Accordingly, only a small portion of the Company’s ALLL is needed for potential losses on nonperforming loans.

The Company also maintains an allowance for certain non-purchased loans and leases not considered impaired where (i) the customer is continuing to make regular payments, although payments may be past due, (ii) there is a reasonable basis to believe the customer may continue to make regular payments, although there is also an elevated risk that the customer may default, and (iii) the collateral or other repayment sources are likely to be insufficient to recover the current investment in the loan or lease if a default occurs. The Company evaluates such loans and leases to determine if an allowance is needed for these loans and leases. For the purpose of calculating the amount of such allowance, management assumes that (i) no further regular payments occur and (ii) all sums recovered will come from liquidation of collateral and collection efforts from other payment sources. To the extent that the Company’s current investment in a particular loan or lease evaluated for the need for such allowance exceeds its net collateral value, such excess is considered allocated allowance for purposes of the determination of the ALLL.

The Company also includes specific ALLL allocations for qualitative factors including, (i) general economic and business conditions, (ii) trends that could affect collateral values and (iii) expectations regarding the current business cycle. The Company may also consider other qualitative factors in future periods for additional ALLL allocations.

Changes in the criteria used in this evaluation or the availability of new information could cause the ALLL to be increased or decreased in future periods. In addition, bank regulatory agencies, as part of their examination process, may require adjustments to the ALLL based on their judgment and estimates.

Premises and Equipment

Premises and equipment – Premises and equipment are reported at cost less accumulated depreciation and amortization. Depreciation and amortization are computed on a straight-line basis over the estimated useful lives of the related assets. Depreciable lives for the major classes of assets are generally 20 to 45 years for buildings and 3 to 25 years for furniture, fixtures, equipment and certain building improvements. Leasehold improvements are amortized over the shorter of the asset’s estimated useful life or the term of the lease. Accelerated depreciation methods are used for income tax purposes. Maintenance and repair charges are expensed as incurred.

Foreclosed Assets

Foreclosed assets – Repossessed personal properties and real estate acquired through or in lieu of foreclosure, excluding purchased foreclosed assets, are initially recorded at the lesser of current principal investment or fair value less estimated cost to sell (generally 8% to 10%) at the date of repossession or foreclosure. Purchased foreclosed assets are initially recorded at Day 1 Fair Values. In estimating such Day 1 Fair Values, management considered a number of factors including, among others, appraised value, estimated selling price, estimated holding periods and net present value (calculated using discount rates ranging from 8.0% to 9.5% per annum) of cash flows expected to be received.

Valuations of all foreclosed assets are periodically reviewed by management with the carrying value of such assets adjusted through non-interest expense to the then estimated fair value, generally based on third party appraisals, broker price opinions or other valuations of the property, net of estimated selling costs, if lower, until disposition. Gains and losses from the sale of such repossessions and real estate acquired through or in lieu of foreclosure are recorded in non-interest income, and expenses to maintain the properties are included in non-interest expense.

Income Taxes

Income taxes – The Company utilizes the asset and liability method in accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based upon the difference between the values of the assets and liabilities as reflected in the financial statements and their related tax basis using enacted tax rates in effect for the year or years in which the differences are expected to be recovered or settled. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes.

As a result of recording, at fair value, acquired assets and assumed liabilities pursuant to business combinations, differences in amounts reported for financial statement purposes and their related basis for federal and state income tax purposes are created. Such differences are recorded as deferred tax assets and liabilities using enacted tax rates in effect for the year or years in which the differences are expected to be recovered or settled. Business combination transactions may result in the acquisition of net operating loss carryforwards and other assets with built-in losses, the realization of which are subject to limitations pursuant to section 382 (“section 382 limitation”) of the Internal Revenue Code (“IRC”). In determining the section 382 limitation associated with a business combination, management must make a number of estimates and assumptions regarding the ability to utilize acquired net operating loss carryforwards and the expected timing of future recoveries or settlements of acquired assets with built-in losses. To the extent that information available as of the date of acquisition results in a determination by management that some portion of acquired net operating loss carryforwards cannot be utilized or assets with built-in losses are expected to be settled or recovered in future periods in which the ability to realize the benefits will be subject to section 382 limitation, a deferred tax asset valuation allowance is established for the estimated amount of the deferred tax assets subject to the section 382 limitation. To the extent that information becomes available, during the first 12 months following the consummation of a business combination transaction, that results in changes in management’s initial estimates and assumptions regarding the expected utilization of acquired net operating loss carryforwards or the expected settlement or recovery of acquired assets with built-in losses subject to section 382 limitation, an increase or decrease of the deferred tax asset valuation allowance will be recorded as an adjustment to bargain purchase gain or goodwill. To the extent that such information becomes available 12 months or more after the consummation of a business combination transaction, or additional information becomes available during the first 12 months as a result of changes in circumstances since the date of the consummation of a business combination transaction, an increase or decrease of the deferred tax asset valuation allowance will be recorded as an adjustment to deferred income tax expense (benefit).

The Company recognizes a tax position as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that has a greater than 50% likelihood of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded.

The Company files consolidated tax returns. The Bank and the other consolidated entities provide for income taxes on a separate return basis and remit to the Company amounts determined to be currently payable. The Company recognizes interest related to income tax matters as interest income or expense, and penalties related to income tax matters are recognized as non-interest expense. The Company is no longer subject to income tax examinations by U.S. federal tax authorities for years prior to 2012.

Bank Owned Life Insurance ("BOLI")

Bank owned life insurance (“BOLI”) – BOLI consists of life insurance purchased by the Company on (i) a qualifying group of officers with the Company designated as owner and beneficiary of the policies and (ii) one of the Company’s executive officers with the Company designated as owner and both the Company and the executive officer designated as beneficiaries of the policies. The earnings on BOLI policies help to offset a portion of employee benefit costs or to offset a portion of the costs of a supplemental executive retirement plan for one of the Company’s executive officers. BOLI is carried at the policies’ realizable cash surrender values with changes in cash surrender values and death benefits received in excess of cash surrender values reported in non-interest income.

Intangible Assets

Intangible assets – Intangible assets consist of goodwill, bank charter costs and core deposit intangibles. Goodwill represents the excess purchase price over the fair value of net assets acquired in business acquisitions. The Company had goodwill of $125.4 million and $78.7 million at December 31, 2015 and 2014, respectively. The Company performed its annual impairment test of goodwill as of September 30, 2015. This test indicated no impairment of the Company’s goodwill.

Bank charter costs represent costs paid to acquire a Texas bank charter and are being amortized over 20 years. Bank charter costs totaled $239,000 at both December 31, 2015 and 2014, less accumulated amortization of $144,000 and $132,000 at December 31, 2015 and 2014, respectively.

Core deposit intangibles represent premiums paid for deposits acquired via acquisition and are being amortized over three to seven years. Core deposit intangibles totaled $41.5 million and $36.5 million at December 31, 2015 and 2014, respectively, less accumulated amortization of $14.7 million and $9.7 million at December 31, 2015 and 2014, respectively.

The aggregate amount of amortization expense for the Company’s core deposit and bank charter intangibles is expected to be $6.2 million in 2016, $5.9 million in 2017, $5.9 million in 2018, $5.5 million in 2019 and $3.0 million in 2020.

Stock-Based Compensation

Stock-based compensation – The Company has a non-qualified employee stock option plan, a non-employee director stock plan and an employee restricted stock plan, each of which is described more fully in Note 16. The Company measures the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. Such cost is recognized over the vesting period of the award.

Earnings Per Common Share

Earnings per common share – Earnings per common share are computed using the two-class method. Basic earnings per common share are computed by dividing net income available to common stockholders by the weighted-average number of common shares outstanding during the applicable period. Diluted earnings per common share are computed by dividing net income available to common stockholders by the weighted-average number of common shares outstanding after consideration of the dilutive effect, if any, of the Company’s common stock options using the treasury stock method. The Company has determined that its outstanding non-vested stock awards granted under its restricted stock plan are participating securities.

Segment Disclosures

Segment disclosures – The Company operates in only one segment – community banking. Accordingly, there is no requirement to report segment information in the Company’s Consolidated Financial Statements. No revenues are derived from foreign countries and no single external customer comprises more than 10% of the Company’s revenues.

Recent Accounting pronouncements

Recent accounting pronouncements – In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers.” ASU 2014-09 provides guidance that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. In August 2015, the FASB issued ASU 2015-14, which defers the effective date of this standard to annual and interim periods beginning after December 15, 2017; however, early adoption is permitted for annual and interim reporting periods beginning after December 15, 2016. The Company is currently evaluating the impact, if any, ASU 2014-09 will have on its financial position, results of operations, and its financial statement disclosures.

In June 2014, the FASB issued ASU 2014-11 “Transfers and Servicing (Topic 860).” ASU 2014-11 amends the accounting guidance for repo-to-maturity transactions and requires such transactions to be accounted for as secured borrowings. In addition, ASU 2014-11 requires enhanced disclosures related to the collateral pledged, maturity and risk associated with repurchase agreements. The Company adopted the provision of ASU 2014-11 beginning April 1, 2015. The adoption of ASU 2014-11 did not have a significant impact on the Company’s financial position or results of operations but did require additional disclosures about the Company’s repurchase agreements.

In January 2015, the FASB issued ASU 2015-01, “Income Statement – Extraordinary and Unusual Items (Subtopic 225-20) – Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items.” ASU 2015-01 eliminates from GAAP the concept of extraordinary items, which, among other things, required an entity to segregate extraordinary items considered to be unusual and infrequent from the results of ordinary operations and show the item separately in the income statement, net of tax, after income from continuing operations. ASU 2015-01 is effective for interim and annual periods beginning after December 15, 2015. ASU 2015-01 is not expected to have a significant impact on the Company’s financial position, results of operations, or its financial statement disclosures.

In February 2015, the FASB issued ASU 2015-02, “Consolidation (Topic 810): Amendments to the Consolidation Analysis” which amends the consolidation requirements of ASU 810 by changing the consolidation analysis required under GAAP. The revised guidance amends the consolidation analysis based on certain fee arrangements or relationships to the reporting entity and, for limited partnerships, requires entities to consider the limited partner’s rights relative to the general partner. ASU 2015-02 is effective for annual and interim periods beginning after December 15, 2015. ASU 2015-02 is not expected to have a significant impact on the Company’s financial position, results of operations, or its financial statement disclosures.

In April 2015, the FASB issued ASU 2015-03, “Interest – Imputation of Interest (Subtopic 835-30) – Simplifying the Presentation of Debt Issuance Costs.” ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in ASU 2015-03. In August 2015, the FASB issued ASU 2015-15 to clarify the Securities and Exchange Commission (“SEC”) staff’s position on presenting and measuring debt issue costs related to line-of-credit arrangements.  ASU 2015-03 and ASU 2015-15 are effective for interim and annual periods beginning after December 15, 2015. ASU 2015-03 and ASU 2015-15 are not expected to have a significant impact on the Company’s financial position, results of operations, or its financial statement disclosures.

In September 2015, the FASB issued ASU 2015-16 “Simplifying the Accounting for Measurement-Period Adjustments.”  ASU 2015-16 requires entities to recognize measurement period adjustments during the reporting period in which the adjustments are determined.  The income effects, if any, of a measurement period adjustment are cumulative and are to be reported in the period in which the adjustment to a provisional amount is determined.  Also, ASU 2015-16 requires presentation on the face of the income statement or in the notes, the effect of the measurement period adjustment as if the adjustment had been recognized at acquisition date.  ASU 2015-16 is effective for fiscal periods beginning after December 15, 2016 and should be applied prospectively to measurement period adjustments that occur after the effective date.

In January 2016, FASB issued ASU 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities.” ASU 2016-01 revises the accounting for the classification and measurement of investments in equity securities and revises the presentation of certain fair value changes for financial liabilities measured at fair value.  For equity securities, the guidance in ASU 2016-01 requires equity investments to be measured at fair value with changes in fair value recognized in net income.  For financial liabilities that are measured at fair value in accordance with the fair value option, the guidance requires presenting, in other comprehensive income, the change in fair value that relates to a change in instrument-specific credit risk. ASU 2016-01 also eliminates the disclosure assumptions used to estimate fair value for financial instruments measured at amortized cost and requires disclosure of an exit price notion in determining the fair value of financial instruments measured at amortized cost.  ASU 2016-01 is effective for interim and annual periods beginning after December 15, 2017.  The Company is evaluating the impact, if any, that ASU 2016-01 will have on its financial position, results of operations, and its financial statement disclosures.

Proposed Accounting Pronouncements

Proposed Accounting Pronouncements – In December 2012, the FASB announced a project related to the impairment of financial instruments in an effort to provide new guidance that would significantly change how entities measure and recognize credit impairment for certain financial assets.  While completion of the project and related guidance is still pending, it is anticipated that new guidance will replace the current incurred loss model that is utilized in estimating the ALLL with a model that requires management to estimate all contractual cash flows that are not expected to be collected over the life of the loan. The FASB describes this revised model as the current expected credit loss (“CECL”) model and believes the CECL model will result in more timely recognition of credit losses since the CECL model incorporates expected credit losses versus incurred credit losses.  The proposed scope of FASB’s CECL model would include loans, held-to-maturity debt instruments, lease receivables, loan commitments and financial guarantees that are not accounted for at fair value.  The final issuance date and the implementation date of the CECL guidance is currently pending, and the Company will continue to monitor FASB’s progress on this project.  

Reclassifications and Recasts

Reclassifications and recasts – Certain reclassifications of prior years’ amounts have been made to conform with the 2015 financial statements presentation. These reclassifications had no impact on prior years’ net income, as previously reported. During the second and fourth quarter of 2015, the Company revised its initial estimates regarding the expected recovery of certain acquired loans and deferred tax assets in its February 10, 2015 acquisition of Intervest. As a result, certain amounts previously reported in the Company’s 2015 interim consolidated financial statements have been recast.

Summary of Assets Acquired and Liabilities Assumed in Acquisition

The following table provides a summary of the assets acquired and liabilities assumed as recorded by Intervest, the fair value adjustments necessary to adjust those acquired assets and assumed liabilities to estimated fair value, the recast adjustments described above and the estimates of the resultant fair values of those assets and liabilities as recorded by the Company. As provided for under GAAP, management has up to 12 months following the date of acquisition to finalize the fair values of the acquired assets and assumed liabilities. Once management has finalized the fair values of acquired assets and assumed liabilities within this 12-month period, management considers such values to be the Day 1 Fair Values.  The fair values shown in the following table have been determined by management to be the Day 1 Fair Values.
