PROSPERITY BANCSHARES, INC. ® AND SUBSIDIARIES

NOTE S TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS

SEPTEMBER 30, 2014

(UNAUDITED)

1. BASIS OF PRESENTATION

The interim consolidated financial statements include the accounts of Prosperity Bancshares, Inc. ® (the “Company”) and its wholly-owned subsidiary, Prosperity Bank ® (the “Bank”). All intercompany transactions and balances have been eliminated.

The accompanying unaudited interim consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the rules and regulations of the Securities and Exchange Commission. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, the statements reflect all adjustments necessary for a fair presentation of the financial position, results of operations and cash flows of the Company on a consolidated basis, and all such adjustments are of a normal recurring nature. These financial statements and the notes thereto should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2013. Operating results for the nine-month period ended September 30, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014 or any other period.

2. INCOME PER COMMON SHARE

Outstanding stock options issued by the Company represent the only dilutive effect reflected in diluted weighted average shares. The following table illustrates the computation of basic and diluted earnings per share:

There were no stock options exercisable during the three and nine months ended September 30, 2014 or 2013 that would have had an anti-dilutive effect on the above computation.

3. NEW ACCOUNTING STANDARDS

Accounting Standards Updates (“ASU”)

ASU 2014-1 2 Compensation-Stock Compensation (Topic 718) - Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period . ”  ASU 2014-12 requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. The performance target should not be reflected in estimating the grant-date fair value of the award. Compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. If the performance target becomes probable of being achieved before the end of the requisite service period, the remaining unrecognized compensation cost should be recognized prospectively over the remaining requisite service period. The total amount of compensation cost recognized during and after the requisite service period should reflect the number of awards that are expected to vest and should be adjusted to reflect those awards that ultimately vest. The requisite service period ends when the employee can cease rendering service and still be eligible to vest in the award if the performance target is achieved. ASU 2014-12 is effective for the Company beginning January 1, 2016 and is not expected to have a significant impact on the Company’s consolidated financial statements.

PROSPERITY BANCSHARES, INC. ® AND SUBSIDIARIES

NOTE S TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS

SEPTEMBER 30, 2014

(UNAUDITED)

ASU 2014-11 “Transfers and Servicing (Topic 860) - Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosure . ”  ASU 2014-11 changes the accounting for repurchase-to-maturity transactions to secured borrowing accounting. It also requires separate accounting for a transfer of a financial asset executed contemporaneously with a repurchase agreement with the same counterparty, which will result in secured borrowing accounting and disclosure for the repurchase agreement.

SEPTEMBER 30, 2014

(UNAUDITED)

Management evaluates debt securities for other-than-temporary impairment (“OTTI”) 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. Investment securities classified as available for sale or held to maturity are evaluated for OTTI under Financial Accounting Standards Board (“FASB”): Accounting Standards Codification (“ASC”) Topic 320, “ Investments-Debt and Equity Securities .”

In determining OTTI, for a majority of the Company's debt securities, 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, 2014, 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 in the Company's securities as of September 30, 2014 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, 2014, management believes any impairment in the Company’s securities is temporary, and therefore 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) Construction, Land Development and Other Land 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.

(iii) 1-4 Family Residential Loans . The Company originates 1-4 family residential mortgage loans (including home equity loans and residential mortgage loans held for sale) collateralized by owner-occupied residential properties located in the Company’s market areas. The Company offers a variety of mortgage loan portfolio 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 retains these portfolio loans for its own account rather than selling them into the secondary market. By doing so, the Company incurs interest rate risk as well as the risks associated with nonpayments on such loans. The Company’s Mortgage Department offers a variety of mortgage loan products which are generally amortized over 30 years, including FHA and VA loans. The Company sells the loans originated by the Mortgage Department into the secondary market.

(vi) 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, 2014, approximately 50.5% of the outstanding principal balance of the Company’s commercial real estate related loans was secured by owner-occupied properties.

(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 “A” 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 180 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 real estate, 1-4 family residential loans, and commercial and industrial loans. As of September 30, 2014 and December 31, 2013, 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, 2014 or December 31, 2013.

Related Party Loans. As of September 30, 2014 and December 31, 2013, loans outstanding to directors, officers and their affiliates totaled $3.1 million and $6.2 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.

Nonperforming Assets and 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.

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, Coppermark Bancshares, Inc. on April 1, 2013, FVNB Corp. on November 1, 2013 and F&M Bancorporation Inc. on April 1, 2014, 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 loans.

The carrying amount of PCI loans included in the consolidated balance sheet and the related outstanding balance as of the dates indicated are presented in the table below.

The outstanding balance represents the total amount owed as of September 30, 2014 and December 31, 2013, including accrued but unpaid interest and any amounts previously charged off. Based on the Company's periodic monitoring and assessment of the portfolio, $440 thousand of allowance for loan losses was required on the PCI loans at September 30, 2014 and no allowance for loan losses was required on PCI loans at December 31, 2013.

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 determined, 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.

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:

Grade 1 – Credits in this category have risk potential that is virtually nonexistent. These loans may be secured by insured certificates of deposit, insured savings accounts, U.S. Government securities and highly rated municipal bonds.

Grade 2 – Credits in this category are of the highest quality. These borrowers represent top rated companies and individuals with unquestionable financial standing with excellent global cash flow coverage, net worth, liquidity and collateral coverage.

NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS

SEPTEMBER 30, 2014

(UNAUDITED)

Grade 3 – Credits in this category are not immune from 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 4 – Credits in this category are considered “pass/watch”. Loans in this category have sources of repayment that remain sufficient to preclude a larger than normal probability of default and secondary sources are likewise currently of sufficient quantity, quality, and liquidity to protect the Bank against loss of principal and interest. These borrowers have specific risk factors, but the overall strength of the credit is acceptable based on other mitigating credit and/or collateral factors and can repay the debt in the normal course of business.

Grade 5 – 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 Bank to risk at a future date. These loans are monitored on the Bank’s internally generated watch list and evaluated on a quarterly basis.

Grade 6 – Credits in this category are considered “substandard” but “non-impaired” loans in accordance with regulatory guidelines. Loans in this category have well-defined weaknesses that, if not corrected, could make default of principal and interest possible. Loans in this category are still accruing interest and may be dependent upon secondary sources of repayment and/or collateral liquidation.

Grade 7 – Credits in this category are deemed “substandard” and “impaired” pursuant to regulatory guidelines. As such, the Bank has determined that it is probable that less than 100% of the contractual principal and interest will be collected. These loans are individually evaluated for a specific reserve valuation and will typically have the accrual of interest stopped.

Grade 8 – Credits in this category include “doubtful” loans in accordance with regulatory guidance. Such loans are no longer accruing interest and factors indicate 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 Bank estimates is collectible.

Grade 9 – Credits in this category are deemed a “loss” in accordance with regulatory guidelines and have been charged off or charged down. The Bank may continue collection efforts and may have partial recovery in the future.

Allowance for Credit Losses. The allowance for credit losses is a valuation allowance 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 probable 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 certain impaired loans, 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 in accordance with ASC Topic 450, “ Contingencies .

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, 2014, the allowance for credit losses totaled $77.6 million or 0.83% of total loans, including acquired loans with discounts. At December 31, 2013, the allowance totaled $67.3 million or 0.87% of total loans, including loans with discounts.

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. Effective July 1, 2011, the Company adopted the provisions of ASU No. 2011-02, “ Receivables (Topic 310)-A Creditor’s Determination of Whether a Restructuring Is a Troubled Debt Restructuring. As such, the Company reassessed all loan modifications occurring since January 1, 2011 for identification as troubled debt restructurings. The following table presents information regarding the recorded balance of loans modified in a troubled debt restructuring during the nine months ended September 30, 2014 and 2013:

As of September 30, 2014, there have been no defaults on any loans that were modified as troubled debt restructurings during the preceding nine months. Default is determined at 90 or more days past due. The modifications primarily related to extending the amortization periods of the loans, which includes loans modified during bankruptcy. The Company did not grant principal reductions on any restructured loans. For the nine months ended September 30, 2014, the Company added $51 thousand in new troubled debt restructurings of which $50 thousand was still outstanding on September 30, 2014. The remaining restructured loans from prior periods are performing and accruing loans. These modifications did not have a material impact on the Company’s determination of the allowance for credit losses.

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 residential mortgage 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. ASC Topic 820 “ Fair Value Measurements and Disclosures ” 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 hierarchy is as follows:

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.

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 assets and 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). These instruments include other real estate owned, repossessed assets, held to maturity debt securities, loans held for sale, and impaired loans. For the three and nine months ended September 30, 2014, the Company had additions to other real estate owned of $1.5 million and $5.9 million, respectively, of which $982 thousand and $3.8 million were outstanding as of September 30, 2014. For the nine months ended September 30, 2014, the Company had additions to impaired loans of $25.5 million, of which $24.7 million were outstanding as of September 30, 2014. The remaining assets and liabilities measured at fair value on a nonrecurring basis that were recorded in 2014 and remained outstanding at September 30, 2014 were not significant.

(UNAUDITED)

The following is a description of the fair value estimates, methods and assumptions that are used by the Company in estimating the fair values of financial instruments.

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 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 2.

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.

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.

(UNAUDITED)

Derivative financial instruments —The fair value of the underlying non-hedging derivative contracts offset each other 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 $2.2 billion at September 30, 2014, 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, 2014. 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.

7. GOODWILL AND CORE DEPOSIT INTANGIBLES

Changes in the carrying amount of the Company’s goodwill and core deposit intangibles (“CDI”) for the nine months ended September 30, 2014 and the year ended December 31, 2013 were as follows:

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, 2014, 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 2014 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 $2.6 million and $1.5 million for the three months ended September 30, 2014 and 2013, respectively, and $7.3 million and $4.6 million for the nine months ended September 30, 2014 and 2013, respectively.

8. STOCK BASED COMPENSATION

At September 30, 2014, 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.

During 2012, the Company’s Board of Directors adopted the Prosperity Bancshares, Inc. 2012 Stock Incentive Plan (the “2012 Plan”), which 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, 2014, no options or other awards have been granted under the 2012 Plan.

The Company received $920 thousand and $1.2 million in cash from the exercise of stock options during the three month periods ended September 30, 2014 and 2013, respectively, and $3.3 million and $3.0 million during the nine month periods ended September 30, 2014 and 2013, 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, 2014 and 2013.

As of September 30, 2014, there was $23.3 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 2.53 years.

In these transactions, the Company has made a loan to a borrower at a variable rate of interest which the borrower pays directly to the Company. The Company also enters into an interest rate swap with a customer to accommodate the customer’s desired terms while at the same time entering into an identical offsetting interest rate swap with another financial institution, thus fully eliminating any interest rate risk to the Company. In connection with each swap transaction, the Company agrees to pay interest to the borrowing customer on a notional amount at a variable interest rate and receive interest from the customer on the same notional amount at a fixed interest rate. At the same time, the Company agrees to pay another financial institution the same fixed interest rate on the same notional amount and receive the same variable interest rate on the same notional amount. The transaction allows the Company’s customer to effectively convert a variable-rate loan to a fixed-rate loan. Because the Company acts solely as an intermediary for its customer, changes in the fair value of the underlying derivative contracts offset each other and do not materially impact the Company’s results of operations. Derivative assets of $184 thousand and derivative liabilities of $184 thousand are recorded in other assets and other liabilities, respectively. The notional amounts and estimated fair values of interest rate derivative contracts outstanding at September 30, 2014 are presented in the following table:

Credit risk arises from the possible inability of counterparties to meet the terms of their contracts. The Company’s exposure is limited to the replacement value of the contracts rather than the notional, principal or contract amounts. Credit risk is minimized through credit approvals, limits, counterparty collateral and monitoring procedures. The Company’s derivative assets and liabilities include certain contractual features in which the Company requires the counterparties to provide collateral in the form of cash and securities to offset changes in the fair value of the derivatives. When necessary, the Company posts collateral primarily in the form of cash to offset changes in fair value of the derivatives, including changes in fair value due to the Company’s credit risk. As of September 30, 2014 and December 31, 2013, the balance of collateral posted by the Company for derivatives was $260 thousand .

The Company believes it has chosen these assumptions or bases in good faith and that they are reasonable. However, the Company cautions you that assumptions or bases almost always vary from actual results, and the differences between assumptions or bases and actual results can be material. The Company undertakes no obligation to publicly update or otherwise revise any forward-looking statements, whether as a result of new information, future events or otherwise.

Management’s Discussion and Analysis of Financial Condition and Results of Operations analyzes the major elements of the Company’s interim consolidated financial statements and accompanying notes. This section should be read in conjunction with the Company’s interim consolidated financial statements and accompanying notes included elsewhere in this report and with the consolidated financial statements and accompanying notes and other detailed information appearing in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013.

Included in this discussion and analysis are descriptions of the composition, performance, and credit quality of the Company’s loan portfolio. The Company has two general categories of loans in its portfolio. Loans originated by Prosperity Bank and made pursuant to the Company’s loan policy and procedures in effect at the time the loan was made are referred to as “legacy loans.” “Acquired loans” refer to all loans acquired in a business combination. Those acquired loans that are renewed or substantially modified after the date of the business combination, which therefore causes them to become subject to the Company’s allowance for credit losses methodology, are referred to as “acquired legacy loans.” Modifications are reviewed for determination of troubled debt restructuring status independently of this process. Acquired loans with a fair value discount or premium at the date of the business combination that remained at the reporting date are referred to as “fair-valued acquired loans.” All fair-valued acquired loans are further categorized into “Non-PCI loans” and “PCI loans” (purchased credit impaired loans). Acquired loans with evidence of credit quality deterioration at acquisition for which it is probable that the Company would not be able to collect all contractual amounts due are PCI loans.

OVERVIEW

The Company, a Texas corporation, was formed in 1983 to acquire the former Allied First Bank in Edna, Texas which was chartered in 1949 as The First National Bank of Edna and is now known as Prosperity Bank (“Prosperity Bank ® ” or the “Bank”). The Company is a registered financial holding company that derives substantially all of its revenues and income from the operation of its bank subsidiary, Prosperity Bank ® . The Bank provides a wide array of financial products and services to small and medium-sized businesses and consumers. As of September 30, 2014, the Bank operated 245 full-service banking locations; with 62 in the Houston area, including The Woodlands; 30 in the South Texas area including Corpus Christi and Victoria; 36 in the Dallas/Fort Worth area; 22 in the East Texas area; 30 in the Central Texas area including Austin and San Antonio; 34 in the West Texas area including Lubbock, Midland-Odessa and Abilene; 16 in the Bryan/College Station area, 6 in the Central Oklahoma area and 9 in the Tulsa, Oklahoma area. The Company’s headquarters are located at Prosperity Bank Plaza, 4295 San Felipe in Houston, Texas and its telephone number is (713) 693-9300. The Company’s website address is www.prosperitybankusa.com. Information contained on the Company’s website is not incorporated by reference into this quarterly report on Form 10-Q and is not part of this or any other report.

The Company generates the majority of its revenues from interest income on loans, service charges on customer accounts and income from investments in securities. The revenues are partially offset by interest expense paid on deposits and other borrowings and noninterest expenses such as administrative and occupancy expenses. Net interest income is the difference between interest income on earning assets such as loans and securities and interest expense on liabilities such as deposits and borrowings which are used to fund those assets. The level of interest rates and the volume and mix of earning assets and interest-bearing liabilities impact net interest income and margin. The Company has recognized increased net interest income due primarily to an increase in the volume of interest-earning assets.

Three principal components of the Company’s growth strategy are internal growth, stringent cost control practices and acquisitions, including strategic merger transactions. The Company focuses on continuous internal growth. Each banking center is operated as a separate profit center, maintaining separate data with respect to its net interest income, efficiency ratio, deposit growth, loan growth and overall profitability. Banking center presidents and managers are accountable for performance in these areas and compensated accordingly. The Company also focuses on maintaining stringent cost control practices and policies. The Company has centralized many of its critical operations, such as data processing and loan processing. Management believes that this centralized infrastructure can accommodate substantial additional growth while enabling the Company to minimize operational costs through certain economies of scale. During 2013, the Company completed the acquisitions of East Texas Financial Services Inc., Coppermark Bancshares, Inc. and FVNB Corp. During 2014, the Company completed the acquisition of F&M Bancorporation Inc.

Total assets were $21.12 billion at September 30, 2014 compared with $18.64 billion at December 31, 2013, an increase of $2.48 billion or 13.3%. Total loans were $9.37 billion at September 30, 2014 compared with $7.78 billion at December 31, 2013, an increase of $1.59 billion or 20.5%. Total deposits were $17.01 billion at September 30, 2014 compared with $15.29 billion at December 31, 2013, an increase of $1.72 billion or 11.3%. Total shareholders’ equity was $3.18 billion at September 30, 2014 compared with $2.79 billion at December 31, 2013, an increase of $396.1 million or 14.2%.

CRITICAL ACCOUNTING POLICIES

The Company’s accounting policies are integral to understanding the financial results reported. Accounting policies are described in detail in Note 1 to the consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013. The Company believes that of its significant accounting policies, the following may involve a higher degree of judgment and complexity:

Allowance for Credit Losses The allowance for credit losses is established through charges to earnings in the form of a provision for credit losses. The determination of the allowance for credit losses has two components, the allowance for legacy credit losses, which includes the allowance for acquired legacy loans, and the allowance for acquired credit losses for fair-valued acquired loans. The allowance for acquired credit losses is calculated as described under the heading “Accounting for Acquired Loans and the Allowance for Acquired Credit Losses” below. Management has established an allowance for credit losses which it believes is adequate for estimated losses in the Company’s loan portfolio. Based on an evaluation of the portfolio, 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. In making its evaluation, management considers factors such as historical loan loss experience, the amount of nonperforming assets and related collateral, the volume, growth and composition of the portfolio, current economic conditions that may affect the borrower’s ability to pay and the value of collateral, the evaluation of the portfolio through its internal loan review process and other relevant factors. Portions of the allowance may be allocated for specific credits; however, the entire allowance is available for any credit that, in management’s judgment, should be charged off. Charge-offs occur when loans are deemed to be uncollectible. For further discussion of the methodology used in the determination of the allowance for credit losses, refer to the “Financial Condition – Allowance for Credit Losses” section below.

Accounting for Acquired Loans and the Allowance for Acquired Credit Losses The Company accounts for its acquisitions using the acquisition method of accounting. Accordingly, the assets, including loans, and liabilities of the acquired entity were recorded at their fair values at the acquisition date. No allowance for credit losses related to the acquired loans is recorded on the acquisition date, as the fair value of the acquired loans incorporates assumptions regarding credit risk. These fair value estimates associated with acquired loans, and based on a discounted cash flow model, include estimates related to market interest rates and undiscounted projections of future cash flows that incorporate expectations of prepayments and the amount and timing of principal, interest and other cash flows, as well as any shortfalls thereof.

At period-end after acquisition, the fair-valued acquired loans from each acquisition are reassessed to determine whether an addition to the allowance for credit losses is appropriate due to further credit quality deterioration. For further discussion of the methodology used in the determination of the allowance for credit losses for fair-valued acquired loans, see “Financial Condition – Allowance for Credit Losses” section below.

Goodwill and Intangible Assets —Goodwill and intangible assets that have indefinite useful lives are subject to an impairment test at least annually, or more often, if events or circumstances indicate that it is more likely than not that the fair value of Prosperity Bank, the Company’s only reporting unit with assigned goodwill, is below the carrying value of its equity. The Company has the option to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining the need to perform step one of the annual test for goodwill impairment. An entity has an unconditional option to bypass the qualitative assessment described in the preceding paragraph for any reporting unit in any period and proceed directly to performing the first step of the goodwill impairment test. An entity may resume performing the qualitative assessment in any subsequent period.

If the Company bypasses the qualitative assessment, a two-step goodwill impairment test is performed. The two-step process begins with an estimation of the fair value of the Company’s reporting unit compared with its carrying value. If the carrying amount exceeds the fair value of the reporting unit, a second test is completed comparing the implied fair value of the reporting unit’s goodwill to its carrying value to measure the amount of impairment.

Estimating the fair value of the Company’s reporting unit is a subjective process involving the use of estimates and judgments, particularly related to future cash flows of the reporting unit, discount rates (including market risk premiums) and market multiples. Material assumptions used in the valuation models include the comparable public company price multiples used in the terminal value, future cash flows and the market risk premium component of the discount rate. The estimated fair values of the reporting unit is determined using a blend of two commonly used valuation techniques: the market approach and the income approach. The Company gives consideration to both valuation techniques, as either technique can be an indicator of value. For the market approach, valuations of the reporting unit were based on an analysis of relevant price multiples in market trades in companies with similar characteristics. For the income approach, estimated future cash flows (derived from internal forecasts and economic expectations) and terminal value (value at the end of the cash flow period, based on price multiples) were discounted. The discount rate was based on the imputed cost of equity capital.

The Company had no intangible assets with indefinite useful lives at September 30, 2014. Other identifiable intangible assets that are subject to amortization are amortized on an accelerated basis over the years expected to be benefited, which the Company believes is between eight and fifteen years. These amortizable intangible assets are reviewed for impairment if circumstances indicate their value may not be recoverable based on a comparison of fair value to carrying value. Based on the Company’s annual goodwill impairment test as of September 30, 2014, management does not believe any of its goodwill is impaired as of September 30, 2014 because the fair value of the Company’s equity substantially exceeded its carrying value. While the Company believes no impairment existed at September 30, 2014, under accounting standards applicable at that date, different conditions or assumptions, or changes in cash flows or profitability, if significantly negative or unfavorable, could have a material adverse effect on the outcome of the Company’s impairment evaluation and financial condition or future results of operations.

Stock-Based Compensation —The Company accounts for stock-based employee compensation plans using the fair value-based method of accounting. The Company’s results of operations reflect compensation expense for all employee stock-based compensation, including the unvested portion of stock options granted prior to 2003. The fair value of stock options granted is estimated at the date of grant using the Black-Scholes option-pricing model. This model requires the input of subjective assumptions including stock price volatility and employee turnover that are utilized to measure compensation expense.

Other-Than-Temporarily Impaired Securities —When the fair value of a security is below its amortized cost, and depending on the length of time the condition exists and the extent the fair market value is below amortized cost, additional analysis is performed to determine whether an impairment exists. Available for sale and held to maturity securities are analyzed quarterly for possible other-than-temporary impairment. The analysis considers (i) the length of time and the extent to which the fair value has been less than cost, (ii) the financial condition and near-term prospects of the issuer, (iii) whether the market decline was affected by macroeconomic conditions, and (iv) 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. Often, the information available to conduct these assessments is limited and rapidly changing, making estimates of fair value subject to judgment. If actual information or conditions are different than estimated, the extent of the impairment of the security may be different than previously estimated, which could have a material effect on the Company’s results of operations and financial condition.

Fair Values of Financial Instruments —The Company determines the fair market values of financial instruments based on the fair value hierarchy established which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. There are three levels of inputs that may be used to measure fair value. Level 1 inputs include quoted market prices in active markets, where available. If such quoted market prices are not available Level 2 inputs are used. These inputs are based upon internally developed models that primarily use observable market-based parameters. Level 3 inputs are unobservable inputs which are typically based on an entity’s own assumptions, as there is little, if any, related market activity. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability.

RESULTS OF OPERATIONS

Net income available to common shareholders was $76.6 million ($1.10 per common share on a diluted basis) for the quarter ended September 30, 2014 compared with $55.3 million ($0.91 per common share on a diluted basis) for the quarter ended September 30, 2013, an increase in net income of $21.3 million or 38.5%. The Company posted annualized returns on average common equity of 9.69% and 9.31%, annualized returns on average assets of 1.45% and 1.37% and efficiency ratios of 41.55% and 41.59% for the quarters ended September 30, 2014 and 2013, respectively. The efficiency ratio is calculated by dividing total non-interest expense, excluding credit loss provisions, by net interest income plus non-interest income, excluding net gains and losses on the sale of securities and assets. Additionally, taxes are not part of this calculation.

For the nine months ended September 30, 2014, net income available to common shareholders was $219.2 million ($3.19 per common share on a diluted basis) compared with $158.4 million ($2.67 per common share on a diluted basis) for the same period in 2013, an increase in net income of $60.8 million or 38.4%. The Company posted annualized returns on average common equity of 9.67% and 9.29%, annualized returns on average assets of 1.44% and 1.33% and efficiency ratios of 42.17% and 42.16% for the nine months ended September 30, 2014 and 2013, respectively.

Net Interest Income

The Company’s net interest income is affected by changes in the amount and mix of interest-earning assets and interest-bearing liabilities, referred to as a “volume change.” It is also affected by changes in yields earned on interest-earning assets and rates paid on interest-bearing deposits and other borrowed funds, referred to as a “rate change.”

Net interest income before the provision for credit losses was $175.7 million for the quarter ended September 30, 2014 compared with $126.5 million for the quarter ended September 30, 2013, an increase of $49.1 million or 38.8%. The increase in net interest income was primarily due to the acquisition of F&M and an increase in average interest-earning assets of $4.10 billion or 28.8%, for the quarter ended September 30, 2014 compared with the quarter ended September 30, 2013, and a decrease in the average rate paid on interest-bearing liabilities of 1 basis point from 0.37% for the quarter ended September 30, 2013 compared with 0.36% for the quarter ended September 30, 2014. Interest income on loans was $140.5 million for the quarter ended September 30, 2014, an increase of $46.3 million or 49.1%, compared with the third quarter of 2013 due in part to an increase in average loans outstanding of $3.21 billion or 52.0%. Additionally, during the third quarters of 2014 and 2013, interest income on loans benefitted from purchase accounting loan discount accretion of $28.5 million and $16.4 million, respectively, which partially offset the decrease in interest rates on the loan portfolio. As of September 30, 2014, the Company had $194.9 million of total outstanding discounts on acquired loans, of which $116.7 million was accretable at September 30, 2014. Interest income on securities was $46.9 million during the third quarter of 2014, an increase of $4.9 million or 11.8%, compared with the third quarter of 2013 due, in part, to an increase in average securities of $821.1 million or 10.2%. Interest income on securities was also impacted by $1.5 million of securities amortization purchase accounting adjustments during the third quarter of 2014. Average interest-bearing liabilities increased $2.47 billion for the quarter ended September 30, 2014 compared with the same period in 2013. The net interest margin on a tax equivalent basis increased 26 basis points from 3.59% for the quarter ended September 30, 2013 to 3.85% for the quarter ended September 30, 2014. The impact of the purchase accounting adjustments on the tax equivalent net interest margin was an increase of 59 basis points for the quarter ended September 30, 2014.

Net interest income before the provision for credit losses increased $140.0 million or 39.6%, to $493.4 million for the nine months ended September 30, 2014 compared with $353.4 million for the same period in 2013. During the nine months ended September 30, 2014 and 2013, interest income on loans benefitted from purchase accounting loan discount accretion of $67.3 million and $42.7 million, respectively. The increase in net interest income was primarily attributable to higher average interest-earning assets as a result of the acquisitions over the past year. The average volume of interest-earning assets increased $3.90 billion for the nine months ended September 30, 2014 compared with the same period in 2013. The net interest margin on a tax equivalent basis increased to 3.77% for the nine months ended September 30, 2014 compared with 3.48% for the same period in 2013. The impact of purchase accounting adjustments on the tax equivalent net interest margin was an increase of 47 basis points.

The following table presents, for the periods indicated, the total dollar amount of average balances, interest income from average interest-earning assets and the resultant yields, as well as the interest expense on average interest-bearing liabilities, expressed in both dollars and rates. Except as indicated in the footnotes, no tax-equivalent adjustments were made and all average balances are daily average balances. Any nonaccruing loans have been included in the table as loans carrying a zero yield.

Provision for Credit Losses

Management actively monitors the Company’s asset quality and provides specific loss provisions when necessary. Provisions for credit losses are charged to income to bring the total allowance for credit losses to a level deemed appropriate by management of the Company based on such factors as historical credit loss experience, industry diversification of the Company’s commercial loan portfolio, the amount of nonperforming loans and related collateral, the volume growth and composition of the loan portfolio, current economic conditions that may affect the borrower’s ability to pay and the value of collateral, the evaluation of the loan portfolio through the internal loan review process and other relevant factors.

Loans are charged-off against the allowance for credit losses when appropriate. Although management believes it uses the best information available to make determinations with respect to the provision for credit losses, future adjustments may be necessary if economic conditions differ from the assumptions used in making the initial determinations.

The Company recorded a $5.0 million provision for credit losses for the quarter ended September 30, 2014 and a $4.0 million provision for the quarter ended September 30, 2013. Net charge-offs were $653 thousand for the quarter ended September 30, 2014 compared with net charge-offs of $288 thousand for the quarter ended September 30, 2013. The Company made an $11.9 million provision for credit losses for the nine months ended September 30, 2014 and a $9.4 million provision for the nine months ended September 30, 2013. Net charge-offs were $1.6 million for the nine months ended September 30, 2014 compared with $2.0 million for the nine months ended September 30, 2013. See "Allowance for Credit Losses" for more information.

Noninterest Income

The Company’s primary sources of recurring noninterest income are NSF fees, credit, debit, and ATM card income and service charges on deposit accounts. Noninterest income does not include loan origination fees which are recognized over the life of the related loan as an adjustment to yield using the interest method. Noninterest income totaled $30.2 million for the three months ended September 30, 2014 compared with $21.6 million for the same period in 2013, an increase of $8.6 million or 39.9%. This increase was primarily due to an increase in NSF fees, credit, debit, and ATM card income, and service charges as a result of the additional accounts acquired from F&M and FVNB. Additionally, trust and brokerage income increased as a result of the additional accounts acquired through the acquisition of FVNB in 2013. While debit card income increased due to higher volume related to acquisitions, income was negatively impacted by the Durbin Amendment beginning in July of 2013. As a result of this legislation, the Federal Reserve imposed limits on the amount of interchange, or swipe, fees that can be collected for financial institutions that have assets of $10 billion or more. The rule provides that the maximum permissible interchange fee for an electronic debit transaction is limited to $0.24.  The fee is calculated as the sum of $0.21 per transaction and 5 basis points multiplied by the value of the transaction. If the card issuer develops and implements certain fraud protection policies and procedures, it may increase its debit card interchange fee up to an additional one cent.

Noninterest income totaled $92.8 million for the nine months ended September 30, 2014 compared with $70.3 million for the same period in 2013, an increase of $22.5 million or 32.0%. This increase was primarily due to the effects of the additional accounts acquired in the acquisitions of FVNB and F&M completed in 2013 and 2014. In addition, gain on the sale of assets increased $4.7 million during the nine months ended September 30, 2014 compared with the same period in 2013, primarily due to a $2.2 million gain that was recorded during the first quarter of 2014 on the sale of the agent bank credit card and agent bank merchant processing business of Bankers Credit Card Services, Inc., a subsidiary acquired as part of the acquisition of Coppermark.

The following table presents, for the periods indicated, the major categories of noninterest income:

Noninterest expense totaled $85.5 million for the quarter ended September 30, 2014 compared with $61.5 million for the quarter ended September 30, 2013, an increase of $24.0 million or 39.0%. Noninterest expense totaled $245.2 million for the nine months ended September 30, 2014 compared with $178.6 million for the nine months ended September 30, 2013, an increase of $66.6 million or 37.3%. Both increases were primarily due to the increases in salaries and employee benefits and general and administrative expenses related to the recent acquisitions. The Company also incurred one-time pre-tax merger related expenses of $338 thousand and $3.1 million for the three months and nine months ended September 30, 2014, respectively. The merger related expenses are reflected on the Company’s income statement for the applicable periods and are reported primarily in the categories of salaries and benefits, data processing and professional fees.

Nonperforming Assets

Nonperforming assets include loans on nonaccrual status, accruing loans 90 days past due or more, and real estate which has been acquired through foreclosure and is awaiting disposition. Nonperforming assets do not include PCI loans unless the timing and amount of projected cashflows can no longer be reasonably estimated. PCI loans become subject to the Company's allowance for credit losses methodology when a deterioration in projected cashflows is identified.

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.

Nonperforming assets increased $27.6 million or 122.5%, to $50.1 million at September 30, 2014 compared with $22.5 million at December 31, 2013, of which $42.9 million and $8.6 million were attributable to acquired loans, respectfully. The ratio of nonperforming assets to loans and other real estate was 0.53% at September 30, 2014 compared with 0.29% at December 31, 2013.

Nonperforming assets were 0.53% of total loans and other real estate at September 30, 2014. Nonperforming assets were 0.97% of total fair-valued acquired loans and other real estate at September 30, 2014. Nonperforming assets were 1.58% of total acquired legacy loans and other real estate at September 30, 2014 and 0.13% of total legacy loans and other real estate at September 30, 2014. The allowance for credit losses as a percentage of total nonperforming loans was 174.2% at September 30, 2014 and 443.3% at December 31, 2013. The increase in nonperforming assets in each acquired loan category during this period is primarily due to the acquisition of F&M.

Allowance for Credit Losses

The allowance for credit losses is a reserve established through charges to earnings in the form of a provision for credit losses. Loans are charged-off against the allowance for credit losses when appropriate. Management has established an allowance for credit losses which it believes is adequate for estimated losses in the Company’s loan portfolio. Although management believes it uses the best information available to make determinations with respect to the allowance for credit losses, future adjustments may be necessary if economic conditions differ from the assumptions used in making the initial determinations. As of September 30, 2014, the allowance for credit losses amounted to $77.6 million or 0.83%, of total loans compared with $67.3 million or 0.87%, of total loans at December 31, 2013.

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 total loan portfolio and assigns risk grades to each loan. 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 certain impaired loans, the Company allocates a specific loan loss reserve primarily based on the value of the collateral securing the impaired loan. The specific reserves are determined on an individual loan basis. Loans for which specific reserves are provided 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 loan that has a specific reserve allocated to it. The Company uses this information to establish the amount of the general valuation allowance.

In determining the allowance for credit losses, management considers the type of loan (legacy or acquired) and the credit quality of the loan. The Company delineates between legacy loans and acquired legacy loans, which are accounted for under the contractual yield method, and fair-valued acquired loans consisting of Non-PCI loans and PCI loans, which are accounted for as purchased loans.

Loans acquired in business combinations are initially recorded at fair value, which includes an estimate of credit losses expected to be realized over the remaining lives of the loans, and therefore no corresponding allowance for loan losses is recorded for these loans at acquisition. When a fair-valued acquired loan is renewed at its maturity date, the loan is re-categorized as an acquired legacy loan. When a fair-valued acquired loan is modified after acquisition, the loan is independently evaluated subsequent to the modification decision to determine whether a substantial modification requires that the loan be re-categorized as an acquired legacy loan. The determination is based on a discounted cash-flow analysis. Generally, when a change in discounted cash-flow of greater than ten percent is identified, the fair-valued acquired loan becomes categorized as an acquired legacy loan. If and when a fair-valued acquired loan becomes an acquired legacy loan, the acquired legacy loan is evaluated at the time of renewal or modification in accordance with the Company’s allowance for credit losses methodology described above.

Non-PCI loans which were not subsequently impaired are considered non-impaired and are evaluated as part of the general valuation allowance. Non-PCI loans that have not become impaired subsequent to acquisition are segregated into a pool for each acquisition for allowance calculation purposes. For each pool, the Company estimates a hypothetical allowance for credit losses also referred to as an “indicated reserve” that is calculated in accordance with GAAP requirements. The Company uses the acquired bank’s past loss history adjusted for qualitative factors to establish the indicated reserve. The indicated reserve for each pool of Non-PCI loans is compared to the remaining discount for the respective pool to test for credit quality deterioration and the possible need for a loan loss provision. To the extent the remaining discount of the pool is greater than the indicated reserve, no additional allowance is necessary. In the event that the remaining discount of the pool is less than the indicated reserve, the difference results in an increase to the allowance recorded through a provision for loan losses.

Non-PCI loans that have deteriorated to an impaired status subsequent to acquisition are evaluated for a specific reserve which, when identified, is added to the allowance for credit losses.

PCI loans are individually monitored on a quarterly basis to assess for deterioration subsequent to acquisition and are only subject to the Company’s allowance methodology when a deterioration in projected cash flows is identified. In the event that a deterioration in cash flows is identified, an additional provision for credit losses is made. PCI loans were recorded at their acquisition date fair values, which were based on expected cash flows and included estimates of expected future credit losses. The Company’s estimates of loan fair values at the acquisition date may be adjusted for a period of up to one year as the Company continues to evaluate its estimate of expected future cash flows at the acquisition date. If the Company determines that losses arose after the acquisition date, the additional losses will be reflected as a provision for credit losses. An allowance for credit losses is not calculated for PCI loans that have not experienced deterioration subsequent to the acquisition date. See “Critical Accounting Policies” for more information.

The Company further disaggregates its allowance for credit losses to distinguish between the portion of the allowance attributed to legacy loans and the portion of the allowance attributed to acquired loans. The following table shows the allocation of the allowance for credit losses among various categories of loans disaggregated between legacy loans, acquired legacy loans, Non-PCI loans and PCI loans. The allocation is made for analytical purposes and is not necessarily indicative of the categories in which future losses may occur. The total allowance is available to absorb losses from any loan category, regardless of whether allocated to a legacy loan or an acquired loan.

At September 30, 2014, the allowance for credit losses totaled $77.6 million compared with $67.3 million at December 31, 2013. At September 30, 2014, $14.8 million of the allowance for credit losses was attributable to acquired loans compared with $7.2 million at December 31, 2013, an increase of $7.6 million or 105.6%. At September 30, 2014, the Company had $194.9 million of total outstanding discounts on acquired loans, of which $116.7 million was accretable.

A change in the allowance for credit losses can be attributable to several factors, including a growth in the balance of legacy loans and the re-categorization of fair-valued acquired loans to acquired legacy loans, which subjects them to the allowance methodolody, historical credit loss information, specific reserves identified for impaired credits and changes in environmental factors. Due to the strong regional economy and historically low credit loss data, the increase in the allowance for credit losses was primarily attributable to a growth in the legacy and acquired legacy loan balances.

The Company believes that the allowance for credit losses at September 30, 2014 and December 31, 2013, is adequate to cover estimated losses in the loan portfolio as of such date. There can be no assurance, however, that the Company will not sustain losses in future periods, which could be substantial in relation to the size of the allowance.

Securities

The carrying cost of securities totaled $8.85 billion at September 30, 2014 compared with $8.22 billion at December 31, 2013, an increase of $621.5 million or 7.6%. At September 30, 2014, securities represented 41.9% of total assets compared with 44.1% of total assets at December 31, 2013.

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. 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 under either model, 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, 2014, 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, 2014, management believes any impairment in the Company’s securities is temporary, and therefore no impairment loss has been realized in the Company’s consolidated statements of income.

Liquidity

Liquidity involves the Company’s ability to raise funds to support asset growth or reduce assets to meet deposit withdrawals and other payment obligations, to maintain reserve requirements and otherwise to operate the Company on an ongoing basis. The Company’s largest source of funds is deposits and its largest use of funds is loans. The Company does not expect a change in the source or use of its funds in the future. Although access to purchased funds from correspondent banks is available and has been utilized on occasion to take advantage of investment opportunities, the Company does not generally rely on these external funding sources. The cash and federal funds sold position, supplemented by amortizing investment and loan portfolios, has generally created an adequate liquidity position.

As of September 30, 2014, the Company had outstanding $2.10 billion in commitments to extend credit and $105.4 million in commitments associated with outstanding standby letters of credit. Since commitments associated with letters of credit and commitments to extend credit may expire unused, the total outstanding may not necessarily reflect the actual future cash funding requirements.

The Company has no exposure to future cash requirements associated with known uncertainties or capital expenditures of a material nature.

Asset liquidity is provided by cash and assets which are readily marketable or which will mature in the near future. As of September 30, 2014, the Company had cash and cash equivalents of $331.4 million compared with $381.4 million at December 31, 2013, a decrease of $50.0 million. The decrease was primarily due to the purchase of $7.25 billion of securities, a decrease in securities sold under repurchase agreements of $6.3 million, a net decrease in deposits of $543.2 million, and dividends paid of $49.4 million. This decrease was partially offset by proceeds from the maturities and repayments of securities of $6.66 billion, a decrease in loans of $75.2 million, net proceeds from short-term borrowings of $280.0 million and net income of $219.2 million.

Contractual Obligations

The following table summarizes the Company’s contractual obligations and other commitments to make future payments as of September 30, 2014 (other than deposit obligations). The payments do not include pre-payment options that may be available to the Company. 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, 2014 are summarized below. Payments for junior subordinated debentures include interest of $82.3 million that will be paid over the future periods. The future interest payments were calculated using the current rate in effect at September 30, 2014. The current principal balance of the junior subordinated debentures at September 30, 2014 was $167.5 million. Payments for FHLB borrowings include interest of $1.9 million that will be paid over the future periods. Payments related to leases are based on actual payments specified in underlying contracts.

Off-Balance Sheet Items

In the normal course of business, the Company enters into various transactions, which, in accordance with accounting principles generally accepted in the United States, are not included in its consolidated balance sheets. The Company enters into these transactions to meet the financing needs of its customers. These transactions include commitments to extend credit and standby letters of credit, which involve, to varying degrees, elements of credit risk and interest rate risk in excess of the amounts recognized in the consolidated balance sheets.

The Company’s commitments associated with outstanding standby letters of credit and commitments to extend credit as of September 30, 2014 are summarized below. Since commitments associated with letters of credit and commitments to extend credit may expire unused, the amounts shown do not necessarily reflect the actual future cash funding requirements:

Capital Resources

Total shareholders’ equity was $3.18 billion at September 30, 2014 compared with $2.79 billion at December 31, 2013, an increase of $396.1 million or 14.2%. The increase was due primarily to net income of $219.2 million, the issuance of common stock in connection with the acquisition of FMBC of $218.2 million and the issuance of common stock in connection with the exercise of stock options and restricted stock awards of $3.3 million, which was partially offset by dividends paid of $49.3 million and stock based compensation expense of $5.9 million for the nine months ended September 30, 2014.

Both the Board of Governors of the Federal Reserve System with respect to the Company, and the Federal Deposit Insurance Corporation (“FDIC”) with respect to the Bank, have established certain minimum risk-based capital standards that apply to bank holding companies and federally insured banks. The following table sets forth the Company’s total risk-based capital, Tier 1 risk-based capital and Tier 1 to average assets (leverage) ratios as of September 30, 2014:

Consolidated Capital Ratios

Total capital (to risk weighted assets)

13.90 %

Tier 1 capital (to risk weighted assets)

13.18 %

Tier 1 capital (to average assets)

7.40 %

As of September 30, 2014, the Bank’s risk-based capital ratios were above the levels required for the Bank to be designated as “well capitalized” by the FDIC. To be designated as “well capitalized”, the minimum ratio requirements for the Bank’s total risk-based capital, Tier 1 risk-based capital, and Tier 1 to average assets (leverage) capital ratios must be 10.0%, 6.0% and 5.0%, respectively. The following table sets forth the Bank’s total risk-based capital, Tier 1 risk-based capital and Tier 1 to average assets (leverage) ratios as of September 30, 2014:

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company manages market risk, which for the Company is primarily interest rate risk, through its Asset Liability Committee which is composed of senior officers of the Company, in accordance with policies approved by the Company’s Board of Directors.

The Company uses simulation analysis to examine the potential effects of market changes on net interest income and market value. The Company considers macroeconomic variables, Company strategy, liquidity and other factors as it quantifies market risk. See Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations-Interest Rate Sensitivity and Liquidity” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013, filed on February 28, 2014, for further discussion.

ITEM 4.

CONTROLS AND PROCEDURES

Evaluation of disclosure controls and procedures. As of the end of the period covered by this report, the Company carried out an evaluation, under the supervision and with the participation of its management, including its Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of its disclosure controls and procedures.
