Accounting Standards Updates (“ASU”) | |
ASU 2012-02 “Intangibles—Goodwill and Other (Topic 350) — Testing Indefinite-Lived Intangible Assets for Impairment.” ASU 2012-02 gives entities the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that an indefinite-lived intangible asset is impaired. If, after assessing the totality of events or circumstances, an entity determines it is more likely than not that an indefinite-lived intangible asset is impaired, then the entity must perform the quantitative impairment test. If, under the quantitative impairment test, the carrying amount of the intangible asset exceeds its fair value, an entity should recognize an impairment loss in the amount of that excess permitting an entity to assess qualitative factors when testing indefinite-lived intangible assets for impairment results in guidance that is similar to the goodwill impairment testing guidance in ASU 2011-08. ASU 2012-02 became effective for the Company on January 1, 2013 and did not have a significant impact on the Company’s financial statements. | |
ASU 2013-02 “Comprehensive Income (Topic 220) — Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income.” ASU 2013-02 amends recent guidance related to the reporting of comprehensive income to enhance the reporting of reclassifications out of accumulated other comprehensive income. ASU 2013-02 became effective for the Company on January 1, 2013 and did not have a significant impact on the Company’s financial statements. See Note 10 – Other Comprehensive (Loss) Income for applicable disclosures. |

Management evaluates securities for other-than-temporary impairment (“OTTI”) at least on a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. The investment securities portfolio is evaluated for OTTI by segregating the portfolio into two general segments and applying the appropriate OTTI model. | |||||||||||||||||||||||||
In determining OTTI, management considers many factors, including: (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, (3) whether the market decline was affected by macroeconomic conditions, and (4) whether the entity has the intent to sell the debt security or more likely than not will be required to sell the debt security before its anticipated recovery. The assessment of whether an other-than-temporary decline exists involves a high degree of subjectivity and judgment and is based on the information available to management at a point in time. | |||||||||||||||||||||||||
When OTTI occurs, the amount of the other-than-temporary impairment recognized in earnings depends on whether an entity intends to sell the security or more likely than not will be required to sell the security before recovery of its amortized cost basis less any current-period credit loss. If an entity intends to sell or more likely than not will be required to sell the security before recovery of its amortized cost basis less any current-period credit loss, the OTTI shall be recognized in earnings equal to the entire difference between the investment’s amortized cost basis and its fair value at the balance sheet date. If an entity does not intend to sell the security and it is not more likely than not that the entity will be required to sell the security before recovery of its amortized cost basis less any current-period loss, the OTTI shall be separated into the amount representing the credit-related portion of the impairment loss (“credit loss”) and the noncredit portion of the impairment loss (“noncredit portion”). The amount of the total OTTI related to the credit loss is determined based on the difference between the present value of cash flows expected to be collected and the amortized cost basis and such difference is recognized in earnings. The amount of the total OTTI related to the noncredit portion is recognized in other comprehensive income, net of applicable taxes. The previous amortized cost basis less the OTTI recognized in earnings shall become the new amortized cost basis of the investment. | |||||||||||||||||||||||||
As of September 30, 2013, the Company does not intend to sell any debt securities and management believes that the Company more likely than not will not be required to sell any debt securities before their anticipated recovery, at which time the Company will receive full value for the securities. Furthermore, as of September 30, 2013, management does not have the intent to sell any of its securities and believes that it is more likely than not that the Company will not have to sell any such securities before a recovery of cost. The unrealized losses are largely due to increases in market interest rates over the yields available at the time the underlying securities were purchased. The fair value is expected to recover as the securities approach their maturity date or repricing date or if market yields for such investments decline. Management does not believe any of the securities are impaired due to reasons of credit quality. Accordingly, as of September 30, 2013, management believes any impairment in the Company’s securities is temporary and no impairment loss has been realized in the Company’s consolidated statements of income. | |||||||||||||||||||||||||

(i) Commercial and Industrial Loans. In nearly all cases, the Company’s commercial loans are made in the Company’s market areas and are underwritten on the basis of the borrower’s ability to service the debt from income. As a general practice, the Company takes as collateral a lien on any available real estate, equipment or other assets owned by the borrower and obtains a personal guaranty of the borrower or principal. Working capital loans are primarily collateralized by short-term assets whereas term loans are primarily collateralized by long-term assets. In general, commercial loans involve more credit risk than residential mortgage loans and commercial mortgage loans and, therefore, usually yield a higher return. The increased risk in commercial loans is due to the type of collateral securing these loans. The increased risk also derives from the expectation that commercial loans generally will be serviced principally from the operations of the business, and those operations may not be successful. Historical trends have shown these types of loans to have higher delinquencies than mortgage loans. As a result of these additional complexities, variables and risks, commercial loans require more thorough underwriting and servicing than other types of loans. | |||||||||||||||||||||||||||||
(ii) Commercial Real Estate. The Company makes commercial real estate related loans collateralized by owner-occupied and non-owner-occupied real estate to finance the purchase of real estate. The Company’s commercial real estate related loans are collateralized by first liens on real estate, typically have variable interest rates (or five year or less fixed rates) and amortize over a 15 to 20 year period. Payments on loans secured by such properties are often dependent on the successful operation or management of the properties. Accordingly, repayment of these loans may be subject to adverse conditions in the real estate market or the economy to a greater extent than other types of loans. The Company seeks to minimize these risks in a variety of ways, including giving careful consideration to the property’s operating history, future operating projections, current and projected occupancy, location and physical condition in connection with underwriting these loans. The underwriting analysis also includes credit verification, analysis of global cash flow, appraisals and a review of the financial condition of the borrower. At September 30, 2013, approximately 38.0% of the outstanding principal balance of the Company’s commercial real estate related loans was secured by owner-occupied properties. | |||||||||||||||||||||||||||||
(iii) 1-4 Family Residential Loans. The Company originates 1-4 family residential mortgage loans and home equity loans collateralized by owner-occupied residential properties located in the Company’s market areas. The Company offers a variety of mortgage loan products which generally are amortized over five to 25 years. Loans collateralized by 1-4 family residential real estate generally have been originated in amounts of no more than 89% of appraised value or have mortgage insurance. The Company requires mortgage title insurance and hazard insurance. The Company has elected to keep all 1-4 family residential loans for its own account rather than selling such loans into the secondary market. By doing so, the Company is able to realize a higher yield on these loans; however, the Company also incurs interest rate risk as well as the risks associated with nonpayments on such loans. | |||||||||||||||||||||||||||||
(iv) Construction and Land Development Loans. The Company makes loans to finance the construction of residential and, to a lesser extent, nonresidential properties. Construction loans generally are collateralized by first liens on real estate and have floating interest rates. The Company conducts periodic inspections, either directly or through an agent, prior to approval of periodic draws on these loans. Underwriting guidelines similar to those described above are also used in the Company’s construction lending activities. Construction loans involve additional risks attributable to the fact that loan funds are advanced upon the security of a project under construction, and the project is of uncertain value prior to its completion. Because of uncertainties inherent in estimating construction costs, the market value of the completed project and the effects of governmental regulation on real property, it can be difficult to accurately evaluate the total funds required to complete a project and the related loan to value ratio. As a result of these uncertainties, construction lending often involves the disbursement of substantial funds with repayment dependent, in part, on the success of the ultimate project rather than the ability of a borrower or guarantor to repay the loan. If the Company is forced to foreclose on a project prior to completion, there is no assurance that the Company will be able to recover all of the unpaid portion of the loan. In addition, the Company may be required to fund additional amounts to complete a project and may have to hold the property for an indeterminate period of time. While the Company has underwriting procedures designed to identify what it believes to be acceptable levels of risks in construction lending, no assurance can be given that these procedures will prevent losses from the risks described above. | |||||||||||||||||||||||||||||
(v) Agriculture Loans. The Company provides agriculture loans for short-term crop production, including rice, cotton, milo and corn, farm equipment financing and agriculture real estate financing. The Company evaluates agriculture borrowers primarily based on their historical profitability, level of experience in their particular agriculture industry, overall financial capacity and the availability of secondary collateral to withstand economic and natural variations common to the industry. Because agriculture loans present a higher level of risk associated with events caused by nature, the Company routinely makes on-site visits and inspections in order to identify and monitor such risks. | |||||||||||||||||||||||||||||
(vi) Consumer Loans. Consumer loans made by the Company include direct credit automobile loans, recreational vehicle loans, boat loans, home improvement loans, personal loans (collateralized and uncollateralized) and deposit account collateralized loans. The terms of these loans typically range from 12 to 120 months and vary based upon the nature of collateral and size of loan. Generally, consumer loans entail greater risk than do real estate secured loans, particularly in the case of consumer loans that are unsecured or collateralized by rapidly depreciating assets such as automobiles. In such cases, any repossessed collateral for a defaulted consumer loan may not provide an adequate source of repayment for the outstanding loan balance. The remaining deficiency often does not warrant further substantial collection efforts against the borrower beyond obtaining a deficiency judgment. In addition, consumer loan collections are dependent on the borrower’s continuing financial stability, and thus are more likely to be adversely affected by job loss, divorce, illness or personal bankruptcy. Furthermore, the application of various federal and state laws may limit the amount which can be recovered on such loans. | |||||||||||||||||||||||||||||
The Company maintains an independent loan review department that reviews and validates the credit risk program on a periodic basis. Results of these reviews are presented to management. The loan review process complements and reinforces the risk identification and assessment decisions made by lenders and credit personnel, as well as the Company’s policies and procedures. | |||||||||||||||||||||||||||||
Concentrations of Credit. Most of the Company’s lending activity occurs within the states of Texas and Oklahoma. The majority of the Company’s loan portfolio consists of commercial and industrial, commercial real estate and 1-4 family residential loans. As of September 30, 2013 and December 31, 2012, there were no concentrations of loans related to any single industry in excess of 10% of total loans. | |||||||||||||||||||||||||||||
Foreign Loans. The Company has U.S. dollar denominated loans and commitments to borrowers in Mexico. The outstanding balance of these loans and the unfunded amounts available under these commitments were not significant at September 30, 2013 or December 31, 2012. | |||||||||||||||||||||||||||||
Related Party Loans. As of September 30, 2013 and December 31, 2012, loans outstanding to directors, officers and their affiliates totaled $6.3 million and $6.7 million, respectively. All transactions entered into between the Company and such related parties are done in the ordinary course of business, made on the same terms and conditions as similar transactions with unaffiliated persons. | |||||||||||||||||||||||||||||
An analysis of activity with respect to these related party loans is as follows: | |||||||||||||||||||||||||||||

Nonaccrual and Past Due Loans. The Company has several procedures in place to assist it in maintaining the overall quality of its loan portfolio. The Company has established underwriting guidelines to be followed by its officers and the Company also monitors its delinquency levels for any negative or adverse trends. There can be no assurance, however, that the Company’s loan portfolio will not become subject to increasing pressures from deteriorating borrower credit due to general economic conditions. | |||||||||||||||||||||||||||||
The Company generally places a loan on nonaccrual status and ceases accruing interest when the payment of principal or interest is delinquent for 90 days, or earlier in some cases, unless the loan is in the process of collection and the underlying collateral fully supports the carrying value of the loan. | |||||||||||||||||||||||||||||
The Company requires appraisals on loans collateralized by real estate. With respect to potential problem loans, an evaluation of the borrower’s overall financial condition is made to determine the need, if any, for possible writedowns or appropriate additions to the allowance for credit losses. | |||||||||||||||||||||||||||||

The Company believes its conservative lending approach has resulted in sound asset quality. The Company had $12.7 million in nonperforming assets at September 30, 2013 compared with $13.0 million at December 31, 2012. If interest on nonaccrual loans had been accrued under the original loan terms, approximately $341,000 and $252,000 would have been recorded as income for the nine months ended September 30, 2013 and 2012, respectively. | |||||||||||||||||||||||||||||
Purchased Credit-Impaired (PCI) Loans. In connection with the acquisition of American State Financial Corporation (ASB) on July 1, 2012, Community National Bank on October 1, 2012, East Texas Financial Services, Inc. on January 1, 2013 and Coppermark Bancshares, Inc. on April 1, 2013, the Company acquired loans both with and without evidence of credit quality deterioration since origination. The acquired loans were initially recorded at fair value with no carryover of any allowance for loan losses. | |||||||||||||||||||||||||||||
Loans acquired with evidence of credit quality deterioration at acquisition for which it was probable that the Company would not be able to collect all contractual amounts due were accounted for as PCI. | |||||||||||||||||||||||||||||
The carrying amount of acquired PCI loans included in the consolidated balance sheet and the related outstanding balance at September 30, 2013 and December 31, 2012 were as follows: | |||||||||||||||||||||||||||||

Impaired Loans. Loans are considered impaired when, based on current information and events, it is probable the Company will be unable to collect all amounts due in accordance with the original contractual terms of the loan agreement, including scheduled principal and interest payments. Impairment is evaluated in total for smaller-balance loans of a similar nature and on an individual loan basis for other loans. If a loan is impaired, a specific valuation allowance is allocated, if necessary, so that the loan is reported net, at the present value of estimated future cash flows using the loan’s existing rate or at the fair value of collateral if repayment is expected solely from the collateral. Interest payments on impaired loans are typically applied to principal unless collectability of the principal amount is reasonably assured, in which case interest is recognized on a cash basis. Impaired loans, or portions thereof, are charged off when deemed uncollectible. | |||||||||||||||||||||||||||||
Impaired loans as of September 30, 2013 are set forth in the following table. No interest income was recognized on impaired loans subsequent to their classification as impaired.

Credit Quality Indicators. As part of the ongoing monitoring of the credit quality of the Company’s loan portfolio and methodology for calculating the allowance for credit losses, management assigns and tracks loan grades to be used as credit quality indicators. The following is a general description of the loan grades used (1-7): | |||||||||||||||||||||||||||||
Grade 1 – Credits in this category are of the highest standards of credit quality with virtually no risk of loss. These borrowers would represent top rated companies and individuals with unquestionable financial standing with excellent global cash flow coverage, net worth, liquidity and collateral coverage and/or secured by CD/savings accounts. | |||||||||||||||||||||||||||||
Grade 2 – Credits in this category are not immune for risk but are well-protected by the collateral and paying capacity of the borrower. These loans may exhibit a minor unfavorable credit factor, but the overall credit is sufficiently strong to minimize the possibility of loss. | |||||||||||||||||||||||||||||
Grade 3 – Credits in this category constitute an undue and unwarranted credit risk, however the factors do not rise to a level of substandard. These credits have potential weaknesses and/or declining trends that, if not corrected, could expose the Company to risk at a future date. Credits graded 3 are monitored on the Company’s internally generated watch list and evaluated on a quarterly basis. | |||||||||||||||||||||||||||||
Grade 4 – Credits in this category are deemed “substandard” loans in accordance with regulatory guidelines. Loans in this category have well-defined weakness that, if not corrected, could make default of principal and interest possible, but it is not yet certain. Loans in this category are still accruing interest and may be dependent upon secondary sources of repayment and/or collateral liquidation. | |||||||||||||||||||||||||||||
Grade 5 – Credits in this category are deemed “substandard” and “impaired” pursuant to regulatory guidelines. As such, the Company has determined that it is probable that less than 100% of the principal and interest will be collected. Loans graded 5 are individually evaluated for a specific reserve valuation and will typically have the accrual of interest stopped. | |||||||||||||||||||||||||||||
Grade 6 – Credits in this category include “doubtful” loans in accordance with regulatory guidance. Such loans are on nonaccrual and factors have indicated a loss is imminent. These loans are also deemed “impaired.” While a specific reserve may be in place while the loan and collateral is being evaluated these loans are typically charged down to an amount the Company deems collectable. | |||||||||||||||||||||||||||||
Grade 7 – Credits in this category are deemed a “loss” in accordance with regulatory guidelines and charged off or charged down. The Company may continue collection efforts and may have partial recovery in the future. | |||||||||||||||||||||||||||||

Allowance for Credit Losses. The allowance for credit losses is a valuation established through charges to earnings in the form of a provision for credit losses. Management has established an allowance for credit losses which it believes is adequate for estimated losses in the Company’s loan portfolio. The amount of the allowance for credit losses is affected by the following: (i) charge-offs of loans that occur when loans are deemed uncollectible and decrease the allowance, (ii) recoveries on loans previously charged off that increase the allowance and (iii) provisions for credit losses charged to earnings that increase the allowance. Based on an evaluation of the loan portfolio and consideration of the factors listed below, management presents a quarterly review of the allowance for credit losses to the Bank’s Board of Directors, indicating any change in the allowance since the last review and any recommendations as to adjustments in the allowance. | |||||||||||||||||||||||||||||
The Company’s allowance for credit losses consists of two components: a specific valuation allowance based on probable losses on specifically identified loans and a general valuation allowance based on historical loan loss experience, general economic conditions and other qualitative risk factors both internal and external to the Company. | |||||||||||||||||||||||||||||
In setting the specific valuation allowance, the Company follows a loan review program to evaluate the credit risk in the loan portfolio. Through this loan review process, the Company maintains an internal list of impaired loans which, along with the delinquency list of loans, helps management assess the overall quality of the loan portfolio and the adequacy of the allowance for credit losses. All loans that have been identified as impaired are reviewed on a quarterly basis in order to determine whether a specific reserve is required. For each impaired loan, the Company allocates a specific loan loss reserve primarily based on the value of the collateral securing the impaired loan requiring a reserve. The specific reserves are determined on an individual loan basis. Impaired loans are excluded from the general valuation allowance described below. | |||||||||||||||||||||||||||||
In determining the amount of the general valuation allowance, management considers factors such as historical loan loss experience, industry diversification of the Company’s commercial loan portfolio, concentration risk of specific loan types, the volume, growth and composition of the Company’s loan portfolio, current economic conditions that may affect the borrower’s ability to pay and the value of collateral, the evaluation of the Company’s loan portfolio through its internal loan review process, general economic conditions and other qualitative risk factors both internal and external to the Company and other relevant factors. | |||||||||||||||||||||||||||||
Based on a review of these factors for each loan type, the Company applies an estimated percentage to the outstanding balance of each loan type, excluding any impaired loan. The Company uses this information to establish the amount of the general valuation allowance. | |||||||||||||||||||||||||||||
In connection with its review of the loan portfolio, the Company considers risk elements attributable to particular loan types or categories in assessing the quality of individual loans. Some of the risk elements include: | |||||||||||||||||||||||||||||
• | for 1-4 family residential mortgage loans, the borrower’s ability to repay the loan, including a consideration of the debt to income ratio and employment and income stability, the loan to value ratio, and the age, condition and marketability of collateral; | ||||||||||||||||||||||||||||
• | for commercial real estate loans and multifamily residential loans, the debt service coverage ratio (income from the property in excess of operating expenses compared to loan payment requirements), operating results of the owner in the case of owner-occupied properties, the loan to value ratio, the age and condition of the collateral and the volatility of income, property value and future operating results typical of properties of that type; | ||||||||||||||||||||||||||||
• | 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 the ability to lease property constructed for lease, the quality and nature of contracts for presale or prelease, if any, experience and ability of the developer and loan to value ratio; | ||||||||||||||||||||||||||||
• | for commercial and industrial loans, the operating results of the commercial, industrial or professional enterprise, the borrower’s business, professional and financial ability and expertise, the specific risks and volatility of income and operating results typical for businesses in that category and the value, nature and marketability of collateral; | ||||||||||||||||||||||||||||
• | for agriculture real estate loans, the experience and financial capability of the borrower, projected debt service coverage of the operations of the borrower and loan to value ratio; and | ||||||||||||||||||||||||||||
• | for non-real estate agriculture loans, the operating results, experience and financial capability of the borrower, historical and expected market conditions and the value, nature and marketability of collateral. | ||||||||||||||||||||||||||||
In addition, for each category, the Company considers secondary sources of income and the financial strength and credit history of the borrower and any guarantors. | |||||||||||||||||||||||||||||
At September 30, 2013, the allowance for credit losses totaled $59.9 million or 0.97% of total loans. At December 31, 2012, the allowance aggregated $52.6 million or 1.01% of total loans. | |||||||||||||||||||||||||||||
The following table details the recorded investment in loans and activity in the allowance for credit losses by portfolio segment for the three and nine months ended September 30, 2013.

Troubled Debt Restructurings. The restructuring of a loan is considered a “troubled debt restructuring” if both (i) the borrower is experiencing financial difficulties and (ii) the creditor has granted a concession. Concessions may include interest rate reductions or below market interest rates, principal forgiveness, restructuring amortization schedules and other actions intended to minimize potential losses. | |||||||||||||||||||||||||||||
During the nine months ended September 30, 2013, a $249,000 loan was restructured. Default is determined at 90 or more days past due. The restructured loans from prior periods are performing and accruing loans. | |||||||||||||||||||||||||||||

FAIR VALUE | ' | ||||||||||||||||||||
6. FAIR VALUE | |||||||||||||||||||||
The Company uses fair value measurements to record fair value adjustments to certain assets and to determine fair value disclosures. Fair values represent the estimated price that would be received from selling an asset or paid to transfer a liability, otherwise known as an “exit price.” Securities available for sale are recorded at fair value on a recurring basis. Additionally, from time to time, the Company may be required to record at fair value other assets on a nonrecurring basis such as certain loans including loans held-for-sale, goodwill and other intangible assets and other real estate owned. These nonrecurring fair value adjustments typically involve application of lower-of-cost-or-market accounting or write downs of individual assets. | |||||||||||||||||||||
Fair Value Hierarchy | |||||||||||||||||||||
The Company groups financial assets and financial liabilities measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. These levels are: | |||||||||||||||||||||
• | Level 1—Quoted prices in active markets for identical assets or liabilities. | ||||||||||||||||||||
• | Level 2—Other significant observable inputs (including quoted prices in active markets for similar assets or liabilities) or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. | ||||||||||||||||||||
• | Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. | ||||||||||||||||||||
The fair value of an asset or liability is the price that would be received to sell that asset or paid to transfer that liability in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a principal market) for such asset or liability. In estimating fair value, the Company utilizes valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. Such valuation techniques are consistently applied. Inputs to valuation techniques include the assumptions that market participants would use in pricing an asset or liability. FASB Accounting Standards Codification (“ASC”) Topic 820 establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets and liabilities and the lowest priority to unobservable inputs. | |||||||||||||||||||||
The fair value disclosures below represent the Company’s estimates based on relevant market information and information about the financial instruments. Fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of the various instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in the above methodologies and assumptions could significantly affect the estimates. | |||||||||||||||||||||

Certain financial assets and financial liabilities are measured at fair value on a nonrecurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). Financial assets measured at fair value on a non-recurring basis during the reported periods include certain impaired loans reported at the fair value of the underlying collateral if repayment is expected solely from the collateral. Collateral values are estimated using Level 2 inputs based on observable market data, typically in the case of real estate collateral. For the nine months ended September 30, 2013, the Company had additions to impaired loans of $5.5 million, of which $1.4 million were outstanding at September 30, 2013. | |||||||||||||||||||||
Financial assets measured at fair value on a nonrecurring basis during the reported periods also include other real estate owned and repossessed assets. For the three and nine months ended September 30, 2013, the Company had additions to other real estate owned of $305,000 and $2.7 million, of which $305,000 and $1.1 million were outstanding at September 30, 2013, respectively. The remaining financial assets and financial liabilities measured at fair value on a non-recurring basis that were recorded in 2013 and remained outstanding at September 30, 2013 were not significant. During the reported periods, all fair value measurements for other real estate owned and repossessed assets utilized Level 2 inputs based on observable market data. There were no transfers between Level 1 and Level 2 assets during the nine months ended September 30, 2013. | |||||||||||||||||||||
The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value: | |||||||||||||||||||||
Cash and due from banks—For these short-term instruments, the carrying amount is a reasonable estimate of fair value. The Company classifies the estimated fair value of these instruments as Level 1. | |||||||||||||||||||||
Federal funds sold—For these short-term instruments, the carrying amount is a reasonable estimate of fair value. The Company classifies the estimated fair value of these instruments as Level 1. | |||||||||||||||||||||
Securities—Fair value measurements based upon quoted prices are considered Level 1 inputs. Level 1 securities consist of U.S. Treasury securities and certain equity securities which are included in the available for sale portfolio. For all other available for sale and held to maturity securities, if quoted prices are not available, fair values are measured using Level 2 inputs. For these securities, the Company generally obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other things. The Company reviews the prices supplied by the independent pricing service, as well as their underlying pricing methodologies, for reasonableness. | |||||||||||||||||||||
Securities available for sale are recorded at fair value on a recurring basis. | |||||||||||||||||||||
Loans held for investment—The Company does not record loans at fair value on a recurring basis. As such, valuation techniques discussed herein for loans are primarily for estimating fair value disclosures. However, from time to time, the Company records nonrecurring fair value adjustments to impaired loans to reflect (1) partial write downs that are based on the observable market price or current appraised value of the collateral, or (2) the full charge-off of the loan carrying value. Where appraisals are not available, estimated cash flows are discounted using a rate commensurate with the credit risk associated with those cash flows. Assumptions regarding credit risk, cash flows and discount rates are judgmentally determined using available market information and specific borrower information. | |||||||||||||||||||||
The estimated fair value approximates carrying value for variable-rate loans that reprice frequently and with no significant change in credit risk. The fair value of fixed-rate loans and variable-rate loans which reprice on an infrequent basis is estimated by discounting future cash flows using the current interest rates at which similar loans with similar terms would be made to borrowers of similar credit quality. An overall valuation adjustment is made for specific credit risks as well as general portfolio credit risk. The Company classifies the estimated fair value of loans held for investment as Level 3. | |||||||||||||||||||||
Loans held for sale— Loans held for sale are carried at the lower of cost or estimated fair value. Fair value for consumer mortgages held for sale is based on commitments on hand from investors or prevailing market prices. As such, the Company classifies loans subjected to nonrecurring fair value adjustments as Level 1. | |||||||||||||||||||||
Federal Home Loan Bank of Dallas Stock—The fair value of FHLB stock is estimated to be equal to its carrying amount as reported in the accompanying Consolidated Balance Sheets, given it is not a publicly traded equity security, it has an adjustable dividend rate, and all transactions in the stock are executed at the stated par value. FHLB stock is considered a Level 1 fair value. | |||||||||||||||||||||
Other real estate owned—Other real estate owned is primarily foreclosed properties securing residential loans and commercial real estate. Foreclosed assets are adjusted to fair value less estimated costs to sell upon transfer of the loans to other real estate owned. Subsequently, these assets are carried at the lower of carrying value or fair value less estimated costs to sell. Other real estate carried at fair value based on an observable market price or a current appraised value is classified by the Company as Level 2. When management determines that the fair value of other real estate requires additional adjustments, either as a result of a non-current appraisal or when there is no observable market price, the Company classifies the other real estate as Level 3. | |||||||||||||||||||||
Deposits—The fair value of demand deposits, savings accounts and certain money market deposits is the amount payable on demand at the reporting date. The fair value of fixed-maturity certificates of deposit is estimated using the rates currently offered for deposits of similar remaining maturities. Deposits fair value measurements utilize Level 2 inputs. | |||||||||||||||||||||
Junior subordinated debentures—The fair value of the junior subordinated debentures was calculated using the quoted market prices, if available. If quoted market prices are not available, fair value is estimated using quoted market prices for similar subordinated debentures. Junior subordinated debentures fair value measurements utilize Level 2 inputs. | |||||||||||||||||||||
Other borrowings—Rates currently available to the Company for debt with similar terms and remaining maturities are used to estimate the fair value of other borrowings using a discounted cash flows methodology and are measured utilizing Level 2 inputs. | |||||||||||||||||||||
Securities sold under repurchase agreements—The fair value of securities sold under repurchase agreements is the amount payable on demand at the reporting date and are measured utilizing Level 2 inputs. | |||||||||||||||||||||
Off-balance sheet financial instruments—The fair value of commitments to extend credit and standby letters of credit is estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreement and the present creditworthiness of the counterparties. The Company has reviewed the unfunded portion of commitments to extend credit as well as standby and other letters of credit, and has determined that the fair value of such financial instruments is not material. The Company classifies the estimated fair value of credit-related financial instruments as Level 3. | |||||||||||||||||||||

The Company’s off-balance sheet commitments including letters of credit, which totaled $1.19 billion at September 30, 2013, are funded at current market rates at the date they are drawn upon. It is management’s opinion that the fair value of these commitments would approximate their carrying value, if drawn upon. | |||||||||||||||||||||
The fair value estimates presented herein are based on pertinent information available to management at September 30, 2013. Although management is not aware of any factors that would significantly affect the estimated fair value amounts, such amounts have not been comprehensively revalued for purposes of these financial statements since those dates and, therefore, current estimates of fair value may differ significantly from the amounts presented herein. |

Goodwill is recorded on the acquisition date of each entity. The Company may record subsequent adjustments to goodwill for amounts undeterminable at acquisition date, such as deferred taxes and real estate valuations, and therefore the goodwill amounts reflected in the table above may change accordingly. The Company initially records the total premium paid on acquisitions as goodwill. After finalizing the valuation, core deposit intangibles are identified and reclassified from goodwill to core deposit intangibles on the balance sheet. This reclassification has no effect on total assets, liabilities, shareholders’ equity, net income or cash flows. Management performs an evaluation annually, and more frequently if a triggering event occurs, of whether any impairment of the goodwill and other intangibles has occurred. If any such impairment is determined, a write-down is recorded. As of September 30, 2013, there were no impairments recorded on goodwill. | |||||||||
The measurement period for the Company to determine the fair value of acquired identifiable assets and assumed liabilities will be at the end of the earlier of (i) twelve months from the date of acquisition or (ii) as soon as the Company receives the information it | |||||||||
was seeking about facts and circumstances that existed as of the date of acquisition. As such, certain acquisitions completed during 2012 and 2013 may be subject to adjustment. | |||||||||
Core deposit intangibles are amortized on an accelerated basis over their estimated lives, which the Company believes is between 8 and 15 years. Amortization expense related to intangible assets totaled $1.5 million and $2.0 million for the three months ended September 30, 2013 and 2012, respectively, and $4.6 million and $5.3 million for the nine months ended September 30, 2013 and 2012, respectively.

8. STOCK BASED COMPENSATION | |
At September 30, 2013, the Company had four stock-based employee compensation plans and one stock option plan assumed in connection with an acquisition under which no additional options will be granted. Two of the four plans adopted by the Company have expired and therefore no additional awards may be issued under those plans. | |
During 2004, the Company’s Board of Directors adopted the Prosperity Bancshares, Inc. 2004 Stock Incentive Plan (the “2004 Plan”) which authorizes the issuance of up to 1,250,000 shares of common stock pursuant to the exercise or grant, as the case may be, of awards under such plan and the shareholders approved the 2004 Plan in 2005. The Company has granted shares with forfeiture restrictions (“restricted stock”) to certain directors, officers and associates under the 2004 Plan. The awardee is not entitled to the shares until they vest, which is generally over a one to five year period, but the awardee is entitled to receive dividends on and vote the shares prior to vesting. The shares granted do not have a cost to the awardee and the only requirement of vesting is continued service to the Company. Compensation cost related to restricted stock is calculated based on the fair value of the shares at the date of grant. If the awardee leaves the Company before the shares vest, the unvested shares are forfeited. | |
On February 22, 2012, the Company’s Board of Directors adopted the Prosperity Bancshares, Inc. 2012 Stock Incentive Plan (the “2012 Plan”), subject to approval by the Company’s shareholders. The Company’s shareholders approved the 2012 Plan at the annual meeting of shareholders on April 17, 2012. The 2012 Plan authorizes the issuance of up to 1,250,000 shares of common stock upon the exercise of options granted under the 2012 Plan or pursuant to the grant or exercise, as the case may be, of other awards granted under the 2012 Plan, including restricted stock, stock appreciation rights, phantom stock awards and performance awards. As of September 30, 2013, no options or other awards have been granted under the 2012 Plan. | |
The Company received $1.2 million and $300,000 in cash from the exercise of stock options during the three-month periods ended September 30, 2013 and 2012, respectively, and $3.0 million and $2.7 million during the nine-month periods ended September 30, 2013 and 2012, respectively. There was no tax benefit realized from option exercises of the share-based payment arrangements during the three and nine month periods ended September 30, 2013 and 2012. | |
As of September 30, 2013, there was $7.0 million of total unrecognized compensation expense related to stock-based compensation arrangements. That cost is expected to be recognized over a weighted average period of 2.5 years. |

The Company’s future cash payments associated with its contractual obligations pursuant to its junior subordinated debentures, FHLB borrowings and operating leases as of September 30, 2013 are summarized below. Payments for junior subordinated debentures include interest of $46.2 million that will be paid over the future periods. The future interest payments were calculated using the current rate in effect at September 30, 2013. The current principal balance of the junior subordinated debentures at September 30, 2013 was $85.1 million. Payments for FHLB borrowings include interest of $2.5 million that will be paid over the future periods.

New Accounting Standards | ' |
ASU 2012-02 “Intangibles—Goodwill and Other (Topic 350) — Testing Indefinite-Lived Intangible Assets for Impairment.” ASU 2012-02 gives entities the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that an indefinite-lived intangible asset is impaired. If, after assessing the totality of events or circumstances, an entity determines it is more likely than not that an indefinite-lived intangible asset is impaired, then the entity must perform the quantitative impairment test. If, under the quantitative impairment test, the carrying amount of the intangible asset exceeds its fair value, an entity should recognize an impairment loss in the amount of that excess permitting an entity to assess qualitative factors when testing indefinite-lived intangible assets for impairment results in guidance that is similar to the goodwill impairment testing guidance in ASU 2011-08. ASU 2012-02 became effective for the Company on January 1, 2013 and did not have a significant impact on the Company’s financial statements. | |
ASU 2013-02 “Comprehensive Income (Topic 220) — Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income.” ASU 2013-02 amends recent guidance related to the reporting of comprehensive income to enhance the reporting of reclassifications out of accumulated other comprehensive income.
