Notes to Consolidated Financial Statements

(Unaudited)

Note 1 — Basis of Presentation

The accounting and reporting policies of International Bancshares Corporation (the “Corporation”) and Subsidiaries (the Corporation and Subsidiaries collectively referred to herein as the “Company”) conform to accounting principles generally accepted in the United States of America and to general practices within the banking industry. The consolidated financial statements include the accounts of the Corporation and its wholly-owned subsidiaries, International Bank of Commerce, Laredo (“IBC”), Commerce Bank, International Bank of Commerce, Zapata, International Bank of Commerce, Brownsville and the Corporation’s wholly-owned non-bank subsidiaries, IBC Subsidiary Corporation, IBC Life Insurance Company, IBC Trading Company, Premier Tierra Holdings, Inc., IBC Charitable and Community Development Corporation, and IBC Capital Corporation. All significant inter-company balances and transactions have been eliminated in consolidation. The consolidated financial statements are unaudited, but include all adjustments, which, in the opinion of management, are necessary for a fair presentation of the results of the periods presented. All such adjustments were of a normal and recurring nature. These financial statements should be read in conjunction with the financial statements and the notes thereto in the Company’s latest Annual Report on Form 10-K. The consolidated statement of condition at December 31, 2015 has been derived from the audited financial statements at that date but does not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements. Certain reclassifications have been made to make prior periods comparable. Operating results for the three months ended March 31, 2016 are not necessarily indicative of the results for the year ending December 31, 2016 or any future period.

The Company operates as one segment. The operating information used by the Company’s chief executive officer for purposes of assessing performance and making operating decisions about the Company is the consolidated statements presented in this report. The Company has four active operating subsidiaries, namely, the bank subsidiaries, known as International Bank of Commerce, Laredo, Commerce Bank, International Bank of Commerce, Zapata and International Bank of Commerce, Brownsville. The Company applies the provisions of Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”), FASB ASC 280, “Segment Reporting,” in determining its reportable segments and related disclosures.

The Company has evaluated all events or transactions that occurred through the date the Company issued these financial statements. During this period, the Company did not have any material recognizable or non-recognizable subsequent events.

Note 2 — Fair Value Measurements

ASC Topic 820, “Fair Value Measurements and Disclosures” (“ASC 820”) defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. ASC 820 applies to all financial instruments that are being measured and reported on a fair value basis. ASC 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date; it also establishes a fair value hierarchy that prioritizes the inputs used in valuation methodologies into the following three levels:

Level 1 Inputs - Unadjusted quoted prices in active markets for identical assets or liabilities.

Level 2 Inputs - Observable inputs other than Level 1 inputs, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; 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 Inputs - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or other

valuation techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation.

A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy is set forth below.

The following table represents assets and liabilities reported on the consolidated balance sheets at their fair value on a recurring basis as of March 31, 2016 by level within the fair value measurement hierarchy:

	$	4,199,372	$	28,457	$	4,149,686	$	21,229

Investment securities available-for-sale are classified within Level 2 and Level 3 of the valuation hierarchy, with the exception of certain equity investments that are classified within Level 1. For investments classified as Level 2 in the fair value hierarchy, the Company obtains fair value measurements for investment securities 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. Investment securities classified as Level 3 are non-agency mortgage-backed securities. The non-agency mortgage-backed securities held by the Company are traded in inactive markets and markets that have experienced significant decreases in volume and level of activity, as evidenced by few recent transactions, a significant decline or absence of new issuances, price quotations that are not based on comparable securities transactions and wide bid-ask spreads among other factors. As a result of the inability to

use quoted market prices to determine fair value for these securities, the Company determined that fair value, as determined by level 3 inputs in the fair value hierarchy, is more appropriate for financial reporting and more consistent with the expected performance of the investments. For the investments classified within level 3 of the fair value hierarchy, the Company used a discounted cash flow model to determine fair value. Inputs in the model included both historical performance and expected future performance based on information currently available.

Assumptions used in the discounted cash flow model as of March 31, 2016 and December 31, 2015 were applied separately to those portions of the bond where the underlying residential mortgage loans had been performing under original contract terms for at least the prior 24 months and those where the underlying residential mortgages had not been meeting the original contractual obligation for the same period. Unobservable inputs included in the model are estimates on future principal prepayment rates and default and loss severity rates. For that portion of the bond where the underlying residential mortgage had been meeting the original contract terms for at least 24 months, the Company used the following estimates in the model: (i) a voluntary prepayment rate of 7%, (ii) a 1% default rate, (iii) a loss severity rate of 25%, and (iv) a discount rate of 13%. The assumptions used in the model for the rest of the bond included the following estimates: (i) a voluntary prepayment rate of 2%, (ii) a default rate of 4.5%, (iii) a loss severity rate that started at 60% for the first year (2012) then declines by 5% for the following five years (2013, 2014, 2015, 2016 and 2017) and remains at 25% thereafter (2018 and beyond), and (iv) a discount rate of 13%. The estimates used in the model to determine fair value are based on observable historical data of the underlying collateral. The model anticipates that the housing market will gradually improve and that the underlying collateral will eventually all perform in accordance with the original contract terms on the bond. Should the number of loans in the underlying collateral that default and go into foreclosure or the severity of the losses in the underlying collateral significantly change, the results of the model would be impacted. The Company will continue to evaluate the actual historical performance of the underlying collateral and will modify the assumptions used in the model as necessary.

The following table presents a reconciliation of activity for such mortgage-backed securities on a net basis (Dollars in Thousands):

Certain financial assets and financial liabilities are measured at fair value on a nonrecurring basis. 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).

The Company’s assets measured at fair value on a non-recurring basis are limited to impaired loans and other real estate owned. Impaired loans are classified within Level 3 of the valuation hierarchy. The fair value of impaired loans is derived in accordance with FASB ASC 310, “Receivables”. Impaired loans are primarily comprised of collateral-dependent commercial loans. Understanding that as the primary sources of loan repayments decline, the secondary repayment source takes on greater significance and correctly evaluating the fair value of that secondary source, the collateral, becomes even more important. Re-measurement of the impaired loan to fair value is done through a specific valuation allowance included in the allowance for probable loan losses. The fair value of impaired loans is based on the fair value of the collateral, as determined through either an appraisal or evaluation process. The basis for the Company’s appraisal and appraisal review process is based on regulatory guidelines and strives to comply with all regulatory appraisal laws, regulations, and the Uniform Standards of Professional Appraisal Practice. All appraisals and evaluations are “as is” (the property’s highest and best use) valuations based on the current conditions of the property/project at that point in time. The determination of the fair value of the collateral is based on the net realizable value, which is the appraised value less any closing costs, when applicable. As of March 31, 2016, the Company had $34,652,000 of impaired commercial collateral dependent loans, of which $17,067,000 had an appraisal performed within the immediately preceding twelve months, and of which $6,731,000 had an evaluation performed within the immediately preceding twelve months. As of December 31, 2015, the Company had $51,021,000 of impaired commercial collateral dependent loans, of which $39,520,000 had an appraisal performed within the immediately preceding twelve months and of which $2,958,000 had an evaluation performed within the immediately preceding twelve months.

The determination to either seek an appraisal or to perform an evaluation begins in weekly credit quality meetings, where the committee analyzes the existing collateral values of the impaired loans and where obsolete

appraisals are identified. In order to determine whether the Company would obtain a new appraisal or perform an internal evaluation to determine the fair value of the collateral, the credit committee reviews the existing appraisal to determine if the collateral value is reasonable in view of the current use of the collateral and the economic environment related to the collateral. If the analysis of the existing appraisal does not find that the collateral value is reasonable under the current circumstances, the Company would obtain a new appraisal on the collateral or perform an internal evaluation of the collateral. The ultimate decision to get a new appraisal rests with the independent credit administration group. A new appraisal is not required if an internal evaluation, as performed by in-house experts, is able to appropriately update the original appraisal assumptions to reflect current market conditions and provide an estimate of the collateral’s market value for impairment analysis. The internal evaluations must be in writing and contain sufficient information detailing the analysis, assumptions and conclusions and they must support performing an evaluation in lieu of ordering a new appraisal.

Other real estate owned is comprised of real estate acquired by foreclosure and deeds in lieu of foreclosure. Other real estate owned is carried at the lower of the recorded investment in the property or its fair value less estimated costs to sell such property (as determined by independent appraisal) within level 3 of the fair value hierarchy. Prior to foreclosure, the value of the underlying loan is written down to the fair value of the real estate to be acquired by a charge to the allowance for probable loan losses, if necessary. The fair value is reviewed periodically and subsequent write-downs are made, accordingly, through a charge to operations. Other real estate owned is included in other assets on the consolidated financial statements. For the three months ended March 31, 2016 and the twelve months ended December 31, 2015, respectively, the Company recorded $232,000 and $696,000 in charges to the allowance for probable loan losses in connection with loans transferred to other real estate owned. For the three months ended March 31, 2016 and the twelve months ended December 31, 2015, respectively, the Company recorded $47,000 and $1,023,000 in adjustments to fair value in connection with other real estate owned.

The fair value estimates, methods, and assumptions for the Company’s financial instruments at March 31, 2016 and December 31, 2015 are outlined below.

Cash and Cash Equivalents

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

Time Deposits with Banks

The carrying amounts of time deposits with banks approximate fair value.

Investment Securities Held-to-Maturity

The carrying amounts of investments held-to-maturity approximate fair value.

Investment Securities

For investment securities, which include U.S. Treasury securities, obligations of other U.S. government agencies, obligations of states and political subdivisions and mortgage pass through and related securities, fair values are 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. See disclosures of fair value of investment securities in Note 6.

Loans

Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type such as commercial, real estate and consumer loans as outlined by regulatory reporting guidelines. Each category is segmented into fixed and variable interest rate terms and by performing and non-performing categories.

For variable rate performing loans, the carrying amount approximates the fair value. For fixed-rate performing loans, except residential mortgage loans, the fair value is calculated by discounting scheduled cash flows through the estimated maturity using estimated market discount rates that reflect the credit and interest rate risk inherent in the loan. For performing residential mortgage loans, fair value is estimated by discounting contractual cash flows adjusted for prepayment estimates using discount rates based on secondary market sources or the primary origination market. Fixed-rate performing loans are within Level 3 of the fair value hierarchy. At March 31, 2016, and December 31, 2015, the carrying amount of fixed-rate performing loans was $1,347,214,000 and $1,383,836,000 respectively, and the estimated fair value was $1,320,755,000 and $1,362,248,000, respectively.

Accrued Interest

The carrying amounts of accrued interest approximate fair value.

Deposits

The fair value of deposits with no stated maturity, such as non-interest bearing demand deposit accounts, savings accounts and interest bearing demand deposit accounts, was equal to the amount payable on demand as of March 31, 2016 and December 31, 2015. The fair value of time deposits is based on the discounted value of contractual cash flows. The discount rate is based on currently offered rates. Time deposits are within Level 3 of the fair value hierarchy. At March 31, 2016 and December 31, 2015, the carrying amount of time deposits was $2,319,797,000 and $2,366,413,000, respectively, and the estimated fair value was $2,319,079,000 and $2,365,390,000, respectively.

Securities Sold Under Repurchase Agreements

Securities sold under repurchase agreements include both short and long-term maturities. Due to the contractual terms of the short-term instruments, the carrying amounts approximated fair value at March 31, 2016 and December 31, 2015. The fair value of the long-term instruments is based on established market spreads using option adjusted spread methodology. Long-term repurchase agreements are within Level 3 of the fair value hierarchy. At March 31, 2016 and December 31, 2015, the carrying amount of long-term repurchase agreements was $560,000,000 and $560,000,000, respectively, and the estimated fair value was $528,038,200 and $527,198,600, respectively.

Junior Subordinated Deferrable Interest Debentures

The Company currently has floating-rate junior subordinated deferrable interest debentures outstanding. Due to the contractual terms of the floating-rate junior subordinated deferrable interest debentures, the carrying amounts approximated fair value at March 31, 2016 and December 31, 2015.

Other Borrowed Funds

The Company currently has short-term borrowings issued from the Federal Home Loan Bank (“FHLB”). Due to the contractual terms of the short-term borrowings, the carrying amounts approximated fair value at March 31, 2016 and December 31, 2015.

Commitments to Extend Credit and Letters of Credit

Commitments to extend credit and fund letters of credit are principally at current interest rates, and, therefore, the carrying amount approximates fair value.

Limitations

Fair value estimates are made at a point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular financial instrument. Because no market exists for a significant portion of the Company’s financial instruments, fair value estimates are based on judgments regarding future expected

loss experience, current economic conditions, risk characteristics of various financial 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 assumptions could significantly affect the estimates.

Fair value estimates are based on existing on- and off-statement of condition financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. Other significant assets and liabilities that are not considered financial assets or liabilities include the bank premises and equipment and core deposit value. In addition, the tax ramifications related to the effect of fair value estimates have not been considered in the above estimates.

Note 4 — Allowance for Probable Loan Losses

The allowance for probable loan losses primarily consists of the aggregate loan loss allowances of the bank subsidiaries. The allowances are established through charges to operations in the form of provisions for probable loan losses. Loan losses or recoveries are charged or credited directly to the allowances. The allowance for probable loan losses of each bank subsidiary is maintained at a level considered appropriate by management, based on estimated probable losses in the loan portfolio. The allowance for probable loan losses is derived from the following elements: (i) allowances established on specific impaired loans, which are based on a review of the individual characteristics of each loan, including the customer’s ability to repay the loan, the underlying collateral values, and the industry in which the customer operates; (ii) allowances based on actual historical loss experience for similar types of loans in the Company’s loan portfolio; and (iii) allowances based on general economic conditions, changes in the mix of loans, company resources, border risk and credit quality indicators, among other things. All segments of the loan portfolio continue to be impacted by the prolonged economic recovery. Loans secured by real estate could be impacted negatively by the continued economic environment and resulting decrease in collateral values. Consumer loans may be impacted by continued and prolonged unemployment rates.

The Company’s management continually reviews the allowance for loan losses of the bank subsidiaries using the amounts determined from the allowances established on specific impaired loans, the allowance established on quantitative historical loss percentages, and the allowance based on qualitative data to establish an appropriate amount to maintain in the Company’s allowance for loan losses. Should any of the factors considered by management in evaluating the adequacy of the allowance for probable loan losses change, the Company’s estimate of probable loan losses could also change, which could affect the level of future provisions for probable loan losses. While the calculation of the allowance for probable loan losses utilizes management’s best judgment and all information reasonably available, the adequacy of the allowance is dependent on a variety of factors beyond the Company’s control, including, among other things, the performance of the entire loan portfolio, the economy, changes in interest rates and the view of regulatory authorities towards loan classifications.

The loan loss provision is determined using the following methods. On a weekly basis, loan past due reports are reviewed by the credit quality committee to determine if a loan has any potential problems and if a loan should be placed on the Company’s internal classified report. Additionally, the Company’s credit department reviews the majority of the Company’s loans for proper internal classification purposes, regardless of whether they are past due, and

segregates any loans with potential problems for further review. The credit department will discuss the potential problem loans with the servicing loan officers to determine any relevant issues that were not discovered in the evaluation. Also, an analysis of loans that is provided through examinations by regulatory authorities is considered in the review process. After the above analysis is completed, the Company determines if a loan should be placed on an internal classified report because of issues related to the analysis of the credit, credit documents, collateral and/or payment history.

The allowance for probable loan losses is a reserve established through a provision for probable loan losses charged to expense, which represents management’s best estimate of probable loan losses when evaluating loans individually or collectively. The increase in losses charged to the allowance for probable loan losses for the three months ended March 31, 2016 can be attributed to further deterioration in a previously identified and charged down relationship primarily secured by multiple pieces of transportation equipment. In March 2016, litigation against the management of the borrower was filed in the State of Nevada, resulting in a going concern issue with the operations of the borrower and the future use of the transportation equipment pledged as collateral on the relationship. As a result, management, in accordance with its credit review procedures, re-evaluated the collateral values on the equipment in light

of the new circumstances and reduced the collateral values accordingly, resulting in a further charge-down of the relationship of approximately $16.8 million, which is included in the losses charged to the allowance in the commercial category in the table detailing March 31, 2016 activity. The impact of the charge-down is also reflected in the various tables in this footnote including impaired loans, non-accrual loans and the credit quality indicator summary. The relationship was classified as Watch-List Impaired at December 31, 2015.

Impaired loans are those loans where it is probable that all amounts due according to contractual terms of the loan agreement will not be collected. The Company has identified these loans through its normal loan review procedures. Impaired loans are measured based on (i) the present value of expected future cash flows discounted at the loan’s effective interest rate; (ii) the loan’s observable market price; or (iii) the fair value of the collateral if the loan is collateral dependent. Substantially all of the Company’s impaired loans are measured at the fair value of the collateral. In limited cases, the Company may use other methods to determine the level of impairment of a loan if such loan is not collateral dependent.

The following tables detail key information regarding the Company’s impaired loans by loan class at March 31, 2016 and December 31, 2015:

A portion of the impaired loans have adequate collateral and credit enhancements not requiring a related allowance for loan loss. The level of impaired loans is reflective of the economic weakness that has been created by the financial crisis, the subsequent economic downturn and prolonged recovery. Management is confident the Company’s loss exposure regarding these credits will be significantly reduced due to the Company’s long-standing practices that emphasize secured lending with strong collateral positions and guarantor support. Management is likewise confident the reserve for probable loan losses is adequate. The Company has no direct exposure to sub-prime loans in its loan portfolio, but the sub-prime crisis has affected the credit markets on a national level, and as a result, the Company has experienced an increasing amount of impaired loans; however, management’s decision to place loans in this category does not necessarily mean that the Company will experience significant losses from these loans or significant increases in impaired loans from these levels.

Management of the Company recognizes the risks associated with these impaired loans. However, management’s decision to place loans in this category does not necessarily mean that losses will occur. In the current environment, troubled loan management can be protracted because of the legal and process problems that delay the collection of an otherwise collectable loan. Additionally, management believes that the collateral related to these impaired loans and/or the secondary support from guarantors mitigates the potential for losses from impaired loans.

The following table details loans accounted for as “troubled debt restructuring,” segregated by loan class. Loans accounted for as troubled debt restructuring are included in impaired loans.

The bank subsidiaries charge off that portion of any loan which management considers to represent a loss as well as that portion of any other loan which is classified as a “loss” by bank examiners. Commercial and industrial or real estate loans are generally considered by management to represent a loss, in whole or part, when an exposure beyond any collateral coverage is apparent and when no further collection of the loss portion is anticipated based on the borrower’s financial condition and general economic conditions in the borrower’s industry. Generally, unsecured consumer loans are charged-off when 90 days past due.

While management of the Company believes that it is generally able to identify borrowers with financial problems reasonably early and to monitor credit extended to such borrowers carefully, there is no precise method of predicting loan losses. The determination that a loan is likely to be uncollectible and that it should be wholly or partially charged-off as a loss is an exercise of judgment. Similarly, the determination of the adequacy of the allowance for probable loan losses can be made only on a subjective basis. It is the judgment of the Company’s management that the allowance for probable loan losses at March 31, 2016 was adequate to absorb probable losses from loans in the portfolio at that date.

The Company’s internal classified report is segregated into the following categories: (i) “Special Review Credits,” (ii) “Watch List-Pass Credits,” or (iii) “Watch List-Substandard Credits.” The loans placed in the “Special Review Credits” category reflect management’s opinion that the loans reflect potential weakness which requires monitoring on a more frequent basis. The “Special Review Credits” are reviewed and discussed on a regular basis with the credit department and the lending staff to determine if a change in category is warranted. The loans placed in the “Watch List-Pass Credits” category reflect the Company’s opinion that the credit contains weaknesses which represent a greater degree of risk, which warrant “extra attention.” The “Watch List-Pass Credits” are reviewed and discussed on a regular basis with the credit department and the lending staff to determine if a change in category is warranted. The loans placed in the “Watch List-Substandard Credits” classification are considered to be potentially inadequately protected by the current sound worth and debt service capacity of the borrower or of any pledged collateral. These credit obligations, even if apparently protected by collateral value, have shown defined weaknesses related to adverse financial, managerial, economic, market or political conditions which may jeopardize repayment of principal and interest. Furthermore, there is the possibility that some future loss could be sustained by the Company if such weaknesses are not corrected. For loans that are classified as impaired, management evaluates these credits in accordance with the provisions of ASC 310-10, “Receivables,” and, if deemed necessary, a specific reserve is allocated to the credit. The specific reserve allocated under ASC 310-10, is based on (i) the present value of expected future cash flows discounted at the loan’s effective interest rate; (ii) the loan’s observable market price; or (iii) the fair value of the collateral if the loan is collateral dependent. Substantially all of the Company’s loans evaluated as impaired under ASC 310-10 are measured using the fair value of collateral method. In limited cases, the Company may use other methods to determine the specific reserve of a loan under ASC 310-10 if such loan is not collateral dependent.

The allowance based on historical loss experience on the Company’s remaining loan portfolio, which includes the “Special Review Credits,” “Watch List - Pass Credits,” and “Watch List - Substandard Credits” is determined by segregating the remaining loan portfolio into certain categories such as commercial loans, installment loans, international loans, loan concentrations and overdrafts. Installment loans are then further segregated by number of days past due. A historical loss percentage, adjusted for (i) management’s evaluation of changes in lending policies and procedures, (ii) current economic conditions in the market area served by the Company, (iii) other risk factors, (iv) the effectiveness of the internal loan review function, (v) changes in loan portfolios, and (vi) the composition and concentration of credit volume is applied to each category. Each category is then added together to determine the allowance allocated under ASC 450-20.

A summary of the loan portfolio by credit quality indicator by loan class at March 31, 2016 and December 31, 2015 is as follows:

The decrease in Special Review credits for March 31, 2016 compared to December 31, 2015 can be attributed to the re-classification of a commercial loan relationship secured mainly by all assets, including contract rights of the borrower to the Watch-List Pass category. The decrease in Watch-List Impaired loans at March 31, 2016 compared to December 31, 2015 can be attributed to the charge-down of the loan relationship that is mainly secured by multiple pieces of transportation equipment previously discussed. Also impacting the Watch-List Pass category at March 31, 2016 is the reclassification of a relationship secured by all assets, equipment, and accounts receivable from Watch-List Substandard to Watch-List Pass category.

Note 5 — Stock Options

On April 5, 2012, the Board of Directors adopted the 2012 International Bancshares Corporation Stock Option Plan (the “2012 Plan”). There are 800,000 shares available for stock option grants under the 2012 Plan. Under the 2012 Plan, both qualified incentive stock options (“ISOs”) and non-qualified stock options (“NQSOs”) may be granted. Options granted may be exercisable for a period of up to 10 years from the date of grant, excluding ISOs granted to 10% shareholders, which may be exercisable for a period of up to only five years. As of March 31, 2016, 186,250 shares were available for future grants under the 2012 Plan.

A summary of option activity under the stock option plans for the three months ended March 31, 2016 is as follows:

Stock-based compensation expense included in the consolidated statements of income for the three months ended March 31, 2016 and March 31, 2015 was approximately $285,000 and $292,000, respectively. As of March 31, 2016, there was approximately $3,078,000 of total unrecognized stock-based compensation cost related to non-vested options granted under the Company plans that will be recognized over a weighted average period of 2.0 years.

Note 6 — Investment Securities

The Company classifies debt and equity securities into one of three categories: held-to maturity, available-for-sale, or trading. Such securities are reassessed for appropriate classification at each reporting date. Securities classified as “held-to-maturity” are carried at amortized cost for financial statement reporting, while securities classified as “available-for-sale” and “trading” are carried at their fair value. Unrealized holding gains and losses are included in net income for those securities classified as “trading,” while unrealized holding gains and losses related to those securities classified as “available-for-sale” are excluded from net income and reported net of tax as other comprehensive income (loss) and accumulated other comprehensive income (loss) until realized, or in the case of losses, when deemed other than temporary.

The amortized cost and estimated fair value by type of investment security at March 31, 2016 are as follows:

Residential mortgage-backed securities are securities primarily issued by the Federal Home Loan Mortgage Corporation (“Freddie Mac”), Federal National Mortgage Association (“Fannie Mae”), and the Government National Mortgage Association (“Ginnie Mae”) or non-government entities. Investments in residential mortgage-backed securities issued by Ginnie Mae are fully guaranteed by the U.S. Government. Investments in residential mortgage-backed securities issued by Freddie Mac and Fannie Mae are not fully guaranteed by the U.S. Government, however, the Company believes that the quality of the bonds is similar to other AAA rated bonds with limited credit risk, particularly given the placement of Fannie Mae and Freddie Mac into conservatorship by the federal government in early September 2008 and because securities issued by others that are collateralized by residential mortgage-backed securities issued by Fannie Mae or Freddie Mac are rated consistently as AAA rated securities.

The amortized cost and fair value of available-for-sale investment securities pledged to qualify for fiduciary powers, to secure public monies as required by law, repurchase agreements and short-term fixed borrowings was $1,870,662,000 and $1,884,970,000, respectively, at March 31, 2016.

Proceeds from the sale of securities available-for-sale were $38,661,000 for the three months ended March 31, 2016, which included $38,341,000 of mortgage-backed securities. Gross gains of $4 and gross losses of $(137,000) were realized on the sales for the three months ended March 31, 2016. Proceeds from the sale of securities available-for-sale were $6,290,000 for the three months ended March 31, 2015, which included $0 of mortgage-backed securities. Gross gains of $0 and gross losses of $(1,000) were realized on the sales for the three months ended March 31, 2015.

Gross unrealized losses on investment securities and the fair value of the related securities, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position at March 31, 2016, were as follows:

The unrealized losses on investments in residential mortgage-backed securities are primarily caused by changes in market interest rates. Residential mortgage-backed securities are primarily securities issued by Freddie Mac, Fannie Mae and Ginnie Mae. The contractual cash obligations of the securities issued by Ginnie Mae are fully guaranteed by the U.S. Government. The contractual cash obligations of the securities issued by Freddie Mac and Fannie Mae are not fully guaranteed by the U.S. Government; however, the Company believes that the quality of the bonds is similar to other AAA rated bonds with limited credit risk, particularly given the placement of Fannie Mae and Freddie Mac into conservatorship by the federal government in early September 2008, and because securities issued by others that are collateralized by residential mortgage-backed securities issued by Fannie Mae and Freddie Mac are rated consistently as AAA rated securities. The decrease in fair value on residential mortgage-backed securities issued by Freddie Mac, Fannie Mae and Ginnie Mae is due to market interest rates. The Company has no intent to sell and will more than likely not be required to sell before a market price recovery or maturity of the securities; therefore, it is the conclusion of the Company that the investments in residential mortgage-backed securities issued by Freddie Mac, Fannie Mae and Ginnie Mae are not considered other-than-temporarily impaired. In addition, the Company has a small investment in non-agency residential mortgage-backed securities that have additional market volatility beyond economically induced interest rate events. The Company has concluded that the investments in non-agency residential mortgage-backed securities are other-than-temporarily impaired due to both credit and other than credit issues. Impairment charges of $124,000 ($80,600, after tax) and $227,000 ($147,550, after tax) were recorded for the quarters ended March 31, 2016 and March 31, 2015, respectively. The impairment charge represents the credit related impairment on the securities.

The unrealized losses on investments in other securities are caused by fluctuations in market interest rates. The underlying cash obligations of the securities are guaranteed by the entity underwriting the debt instrument. The Company believes that the entity issuing the debt will honor its interest payment schedule, as well as the full debt at maturity. The decrease in fair value is primarily due to market interest rates and not other factors, and because the Company has no intent to sell and will more than likely not be required to sell before a market price recovery or maturity of the securities, it is the conclusion of the Company that the investments are not considered other-than-temporarily impaired.

Note 7 — Other Borrowed Funds

Other borrowed funds include FHLB borrowings, which are short-term and long-term borrowings issued by the FHLB of Dallas at the market price offered at the time of funding. These borrowings are secured by residential mortgage-backed investment securities and a portion of the Company’s loan portfolio. At March 31, 2016, other borrowed funds totaled $499,650,000, a decrease of 1.2% from $505,750,000 at December 31, 2015. The decrease in borrowings can be primarily attributed to the use of funds generated from principal paydowns on available for sale securities.

Note 8 — Junior Subordinated Interest Deferrable Debentures

The Company has formed six statutory business trusts under the laws of the State of Delaware, for the purpose of issuing trust preferred securities. The six statutory business trusts formed by the Company (the “Trusts”) have each issued Capital and Common Securities and invested the proceeds thereof in an equivalent amount of junior subordinated debentures (the “Debentures”) issued by the Company. As of March 31, 2016 and December 31, 2015, the principal amount of debentures outstanding totaled $161,416,000. On July 29, 2015, the Company bought back a portion of the Capital Securities of IB Capital Trusts X and XI from the holder of the securities for a price that reflected an approximate 24.5% discount from the redemption prices of the securities. The Company thereby retired $13,000,000 of the total $34,021,000 of related Junior Subordinated Deferrable Interest Debentures related to IB Capital Trust X resulting in Junior Subordinated Deferrable Interest Debentures on Trust X and $1,000,000 of the total $27,900,000 of related Junior Subordinated Deferrable Interest Debentures related to IB Capital Trust XI.

The Debentures are subordinated and junior in right of payment to all present and future senior indebtedness (as defined in the respective indentures) of the Company, and are pari passu with one another. The interest rate payable on, and the payment terms of the Debentures are the same as the distribution rate and payment terms of the respective issues of Capital and Common Securities issued by the Trusts. The Company has fully and unconditionally guaranteed the obligations of each of the Trusts with respect to the Capital and Common Securities. The Company has the right, unless an Event of Default (as defined in the Indentures) has occurred and is continuing, to defer payment of interest on the Debentures for up to twenty consecutive quarterly periods on Trusts VI, VIII, IX, X, XI and XII. If interest payments on any of the Debentures are deferred, distributions on both the Capital and Common Securities related to that Debenture would also be deferred. The redemption prior to maturity of any of the Debentures may require the prior approval of the Federal Reserve and/or other regulatory bodies.

For financial reporting purposes, the Trusts are treated as investments of the Company and not consolidated in the consolidated financial statements. Although the Capital Securities issued by each of the Trusts are not included as a component of shareholders’ equity on the consolidated statement of condition, the Capital Securities are treated as capital for regulatory purposes. Specifically, under applicable regulatory guidelines, the Capital Securities issued by the Trusts qualify as Tier 1 capital up to a maximum of 25% of Tier 1 capital on an aggregate basis. Any amount that

exceeds the 25% threshold would qualify as Tier 2 capital. At March 31, 2016 and December 31, 2015, the total $161,416,000 of the Capital Securities outstanding qualified as Tier 1 capital.

The Capital Securities may be redeemed in whole or in part on any interest payment date after the Optional Redemption Date.

Note 9 — Common Stock and Dividends

Prior to the redemption in 2012, the Company had outstanding 216,000 shares of Series A cumulative perpetual preferred stock (the “Senior Preferred Stock”), issued to the US Treasury under the Company’s participation in the Troubled Asset Relief Program Capital Purchase Program (the “TARP Capital Purchase Program”). In conjunction with the purchase of the Senior Preferred Stock, the US Treasury received a warrant (the “Warrant”) to purchase 1,326,238 shares of the Company’s common stock (the “Warrant Shares”) at $24.43 per share, which would represent an aggregate common stock investment in the Company on exercise of the warrant in full equal to 15% of the Senior Preferred Stock investment. The term of the Warrant is ten years and was immediately exercisable. The Warrant is included as a component of Tier 1 capital. On June 12, 2013, the U.S. Treasury sold the Warrant to a third party. As of March 31, 2016, the Warrant is still outstanding, but expires on December 23, 2018 with no value if not exercised before that date. Adjustments to the $24.43 per share Exercise Price of the Warrant will be made if the Company pays cash dividends in excess of $.33 per semi-annual period or makes certain other shareholder distributions before the Warrant expires on December 23, 2018.

The Company paid cash dividends to the common shareholders of $.29 per share on April 18, 2016 to all holders of record on April 1, 2016. The Company paid cash dividends to the common shareholders on April 17, 2015 and October 15, 2015 to all holders of record on April 1, 2015 and September 30, 2015.

In April 2009, following receipt of the Treasury Department’s consent, the Board of Directors re-established a formal stock repurchase program that authorized the repurchase of up to $40 million of common stock within the following twelve months and on March 15, 2016, the Board of Directors extended the repurchase program and again authorized the repurchase of up to $40 million of common stock during the 12 month period commencing on April 9, 2016, which repurchase cap the Board is inclined to increase over time. Stock repurchases may be made from time to time, on the open market or through private transactions. Shares repurchased in this program will be held in treasury for reissue for various corporate purposes, including employee stock option plans. During the first quarter of 2016, the Company’s Board of Directors adopted a Rule 10b5-1 plan and intends to adopt additional Rule 10b5-1 trading plans that will allow the Company to purchase its shares of common stock during certain trading blackout periods when the Company ordinarily would not be in the market due to trading restrictions in its internal trading policy. During the term of a 10b5-1 plan, purchases of common stock are automatic to the extent the conditions of the 10b5-1 plan’s trading instructions are met. Shares repurchased in this program will be held in treasury for reissue for various corporate

purposes, including employee stock option plans. As of May 3, 2016, a total of 9,240,629 shares had been repurchased under all programs at a cost of $271,096,000. The Company is not obligated to repurchase shares under its stock repurchase program or to enter into additional Rule 10b5-1 plans. The timing, actual number and value of shares purchased will depend on many factors, including the Company’s cash flow and the liquidity and price performance of its shares of common stock.

Note 10 — Commitments and Contingent Liabilities and Other Tax Matters

The Company is involved in various legal proceedings that are in various stages of litigation. Some of these actions allege “lender liability” claims on a variety of theories and claim substantial actual and punitive damages. The Company has determined, based on discussions with its counsel, that any material loss in such actions, individually or in the aggregate, is remote or the damages sought, even if fully recovered, would not be considered material to the consolidated financial position or results of operations of the Company. However, many of these matters are in various stages of proceedings and further developments could cause management to revise its assessment of these matters.

Note 11 — Capital Ratios

Banks and bank holding companies are subject to various regulatory capital requirements administered by state and federal banking agencies. Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations, involve quantitative measures of assets, liabilities, and certain off-balance sheet items calculated under regulatory accounting practices. Capital amount and classifications are also subject to qualitative judgements by regulators about components, risk-weighting and other factors.

In July 2013, the Federal Deposit Insurance Corporation (“FDIC”) and other regulatory bodies established a new, comprehensive capital framework for U.S. banking organizations, consisting of minimum requirements that increase both the quantity and quality of capital required to be held by banking organizations. The final rules are a result of the implementation of the BASEL III capital reforms and various Dodd-Frank Act related capital provisions. Consistent with the Basel international framework, the rules include a minimum ratio of Common Equity Tier 1 (“CET1”) to risk-weighted assets of 4.5% and a CET1 capital conservation buffer of 2.5% of risk-weighted assets. The capital conservation buffer began being phased-in on January 1, 2016 at .625% and will increase each year until January 1, 2019, when the Company will be required to have a 2.5% capital conservation buffer, effectively resulting in a minimum ratio of CET1 capital to risk-weighted assets of at least 7% upon full implementation. The rules also raised the minimum ratio of Tier 1 capital to risk-weighted assets from 4% to 6% and include a minimum leverage ratio of 4% for all banking organizations. Regarding the quality of capital, the rules emphasize CET1 capital and implements strict eligibility criteria for regulatory capital instruments. The rules also improve the methodology for calculating risk-weighted assets to enhance risk sensitivity. The rules are subject to a four-year phase-in period for mandatory compliance and the Company began phasing in the rules on January 1, 2015.

The Company had a CET1 to risk-weighted assets ratio of 16.78% on March 31, 2016 and 16.81% on December 31, 2015. The Company had a Tier 1 capital-to-average-total-asset (leverage) ratio of 13.39% and 13.15%, risk-weighted Tier 1 capital ratio of 18.64% and 18.69% and risk-weighted total capital ratio of 19.43% and 19.54% at March 31, 2016 and December 31, 2015, respectively. The Company’s CET1 capital consists of common stock and related surplus, net of treasury stock, and retained earnings. The Company and its subsidiary banks elected to opt-out of the requirement to include most components of accumulated other comprehensive income (loss) in the calculation of CET1 capital. CET1 is reduced by goodwill and other intangible assets, net of associated deferred tax liabilities and subject to transition provisions. Tier 1 capital includes CET1 capital and additional Tier 1 capital. Additional Tier 1 capital of the Company includes the Capital Securities issued by the Trusts (see Note 8 above) up to a maximum of 25% of Tier 1 capital on an aggregate basis. Any amount that exceeds the 25% threshold qualifies as Tier 2 capital. As of March 31, 2016, the total of $161,416,000 of the Capital Securities outstanding qualified as Tier 1 capital. The Company actively monitors the regulatory capital ratios to ensure that the Company’s bank subsidiaries are well-capitalized under the regulatory framework.

goodwill and other intangible assets, allocated by risk-weight category, and certain off-balance-sheet items, among other things. The leverage ratio is calculated by dividing Tier 1 capital by adjusted quarterly average total assets, which exclude goodwill and other intangible assets, among other things.

The aforementioned capital conservation buffer is designed to absorb losses during periods of economic stress. Banking institutions with a ratio of CET1 capital-to-risk-weighted assets above the minimum but below the conservation buffer will face constraints on dividends, equity repurchases and compensation based on the amount of the shortfall.

As of March 31, 2016, capital levels at the Company exceed all capital adequacy requirements under the Basel III Capital Rules as currently applicable to the Company, including the capital conservation buffer. Based on the ratios presented above, capital levels as of March 31, 2016 at the Company exceed the minimum levels necessary to be considered “well-capitalized.”

The Company and its subsidiary banks are subject to the regulatory capital requirements administered by the Federal Reserve, and, for the subsidiary banks, the FDIC. Regulatory authorities can initiate certain mandatory actions if the Company or any of the subsidiary banks fail to meet the minimum capital requirements, which could have a direct material effect on our financial statements. Management believes, as of March 31, 2016, that the Company and each of its subsidiary banks meet all capital adequacy requirements to which they are subject.

Overview

The Company, which is headquartered in Laredo, Texas, with 206 facilities and more than 315 ATMs, provides banking services for commercial, consumer and international customers of South, Central and Southeast Texas and the State of Oklahoma. The Company is one of the largest independent commercial bank holding companies headquartered in Texas. The Company, through its bank subsidiaries, is in the business of gathering funds from various sources and investing those funds in order to earn a return. The Company, either directly or through a bank subsidiary, owns two insurance agencies, a liquidating subsidiary, a broker/dealer and a fifty percent interest in an investment banking unit that owns a broker/dealer. The Company’s primary earnings come from the spread between the interest earned on interest-bearing assets and the interest paid on interest-bearing liabilities. In addition, the Company generates income from fees on products offered to commercial, consumer and international customers.

The Company is very active in facilitating trade along the United States border with Mexico. The Company does a large amount of business with customers domiciled in Mexico. Deposits from persons and entities domiciled in Mexico comprise a large and stable portion of the deposit base of the Company’s bank subsidiaries. The Company also serves the growing Hispanic population through the Company’s facilities located throughout South, Central and Southeast Texas and the State of Oklahoma.

Expense control is an essential element in the Company’s long-term profitability. As a result, the Company monitors the efficiency ratio, which is a measure of non-interest expense to net interest income plus non-interest income closely. As the Company adjusts to regulatory changes related to the Dodd-Frank Act, the Company’s efficiency ratio may suffer because the additional regulatory compliance costs are expected to increase non-interest expense. The Company monitors this ratio over time to assess the Company’s efficiency relative to its peers. The Company uses this measure as one factor in determining if the Company is accomplishing its long-term goals of providing superior returns to the Company’s shareholders.

Net Income

Net income for the first quarter of 2016 decreased by 8%, when compared to the same period in 2015. Net income for the three months ended March 31, 2016 was positively impacted by the sale of two investments by a merchant banking entity in which the Company holds a majority interest. Net income for the three months ended March 31, 2016 was negatively impacted by an increase in the provision for probable loan losses during the period as a result of an increase in the portion of the allowance for probable loan losses calculated based on actual historical loss experience in the commercial loan category of the Company’s loan portfolio and losses charged to the allowance for probable loan losses attributable to further deterioration of a previously identified relationship primarily secured by multiple pieces of transportation equipment.

Net interest income is the spread between income on interest earning assets, such as loans and securities, and the interest expense on liabilities used to fund those assets, such as deposits, repurchase agreements and funds borrowed. As part of its strategy to manage interest rate risk, the Company strives to manage both assets and liabilities so that interest sensitivities match. One method of calculating interest rate sensitivity is through gap analysis. A gap is the difference between the amount of interest rate sensitive assets and interest rate sensitive liabilities that re-price or mature in a given time period. Positive gaps occur when interest rate sensitive assets exceed interest rate sensitive liabilities, and negative gaps occur when interest rate sensitive liabilities exceed interest rate sensitive assets. A positive gap position in a period of rising interest rates should have a positive effect on net interest income as assets will re-price faster than liabilities. Conversely, net interest income should contract somewhat in a period of falling interest rates. Management can quickly change the Company’s interest rate position at any given point in time as market conditions dictate. Additionally, interest rate changes do not affect all categories of assets and liabilities equally or at the same time. Analytical techniques employed by the Company to supplement gap analysis include simulation analysis to quantify interest rate risk exposure. The gap analysis prepared by management is reviewed by the Investment Committee of the Company twice a year (see table on page 39 for the March 31, 2016 gap analysis). Management currently believes that the Company is properly positioned for interest rate changes; however if management determines at any time that the Company is not properly positioned, it will strive to adjust the interest rate sensitive assets and liabilities in order to manage the effect of interest rate changes.

Financial Condition

Allowance for Probable Loan Losses

The allowance for probable loan losses decreased 7.8% to $61,784,000 at March 31, 2016 from $66,988,000 at December 31, 2015. The provision for possible loan losses charged to expense increased 284.3% to $9,134,000 for the three months ended March 31, 2016 compared to $2,377,000 for the three months ended March 31, 2015. The increase in the provision for possible loan losses charged to expense can be attributed to increase in the portion of the allowance

for probable loan losses calculated based on actual historical loss experience in the commercial loan category of the Company’s loan portfolio. The increase in the historical loss experience on commercial loans used in the allowance calculation can be attributed to further deterioration on a previously identified and charged down relationship primarily secured by multiple pieces of transportation equipment. In March 2016, litigation against the management of the borrower was filed in the State of Nevada, resulting in a going concern issue with the operations of the borrower and the future use of the transportation equipment pledged as collateral on the relationship. As a result, management, in accordance with its credit review procedures, re-evaluated the collateral values on the equipment in light of the new circumstances and reduced the collateral values accordingly. The allowance for probable loan losses was 1.04% and 1.13% of total loans at March 31, 2016 and December 31, 2015, respectively.

Investment Securities

Residential mortgage-backed securities are securities primarily issued by Freddie Mac, Fannie Mae, Ginnie Mae, and other non-governmental entities. Investments in residential mortgage-backed securities issued by Ginnie Mae are fully guaranteed by the U.S. Government. Investments in residential mortgage-backed securities issued by Freddie Mac and Fannie Mae are not fully guaranteed by the U.S. Government, however, the Company believes that the quality of the bonds is similar to other AAA rated bonds with limited credit risk, particularly given the placement of Fannie Mae and Freddie Mac into conservatorship by the federal government in early September 2008 and because securities issued by others that are collateralized by residential mortgage-backed securities issued by Fannie Mae or Freddie Mac are rated consistently as AAA rated securities.

Loans

Net loans decreased .2% to $5,873,790,000 at March 31, 2016, from $5,883,926,000 at December 31, 2015.

Deposits

Deposits increased by .9% to $8,613,733,000 at March 31, 2016, from $8,536,253,000 at December 31, 2015. The increase in deposits is the result of the increased availability of deposits in the banking market. Even though the Company increased its deposits, the Company is still experiencing a substantial amount of competition for deposits at higher than market rates. As a result, the Company has attempted to maintain certain deposit relationships but has allowed certain deposits to leave as the result of aggressive pricing.

Foreign Operations

On March 31, 2016, the Company had $11,878,689,000 of consolidated assets, of which approximately $176,681,000, or 1.48%, was related to loans outstanding to borrowers domiciled in foreign countries, compared to $179,013,000, or 1.52%, at December 31, 2015. Of the $176,681,000, 84.0% is directly or indirectly secured by U.S. assets, certificates of deposits and real estate; 15.6% is secured by foreign real estate or other assets; and .4% is unsecured.

Critical Accounting Policies

The Company has established various accounting policies that govern the application of accounting principles in the preparation of the Company’s consolidated financial statements. The significant accounting policies are described in the notes to the consolidated financial statements. Certain accounting policies involve significant subjective judgments and assumptions by management that have a material impact on the carrying value of certain assets and liabilities; management considers such accounting policies to be critical accounting policies.

The Company considers its allowance for probable loan losses as a policy critical to the sound operations of the bank subsidiaries. The allowance for probable loan losses primarily consists of the aggregate loan loss allowances of the bank subsidiaries. The allowances are established through charges to operations in the form of provisions for probable loan losses. Loan losses or recoveries are charged or credited directly to the allowances. The allowance for probable loan losses of each bank subsidiary is maintained at a level considered appropriate by management, based on estimated

probable losses in the loan portfolio. The allowance is derived from the following elements: (i) allowances established on specific impaired loans, which are based on a review of the individual characteristics of each loan, including the customer’s ability to repay the loan, the underlying collateral values, and the industry in which the customer operates; (ii) allowances based on actual historical loss experience for similar types of loans in the Company’s loan portfolio; and (iii) allowances based on general economic conditions, changes in the mix of loans, Company resources, border risk and credit quality indicators, among other things. See also discussion regarding the allowance for probable loan losses and provision for probable loan losses included in the results of operations and “Provision and Allowance for Probable Loan Losses” included in Notes 1 and 4 of the notes to Consolidated Financial Statements in the Company’s latest Annual Report on Form 10-K for further information regarding the Company’s provision and allowance for probable loan losses policy.

Liquidity and Capital Resources

The maintenance of adequate liquidity provides the Company’s bank subsidiaries with the ability to meet potential depositor withdrawals, provide for customer credit needs, maintain adequate statutory reserve levels and take full advantage of high-yield investment opportunities as they arise. Liquidity is afforded by access to financial markets and by holding appropriate amounts of liquid assets. The Company’s bank subsidiaries derive their liquidity largely from deposits of individuals and business entities. Deposits from persons and entities domiciled in Mexico comprise a stable portion of the deposit base of the Company’s bank subsidiaries. Other important funding sources for the Company’s bank subsidiaries during 2016 and 2015 were borrowings from the FHLB, securities sold under repurchase agreements and large certificates of deposit, requiring management to closely monitor its asset/liability mix in terms of both rate sensitivity and maturity distribution. The borrowings from FHLB are primarily short-term in nature and are renewed at maturity. The Company’s bank subsidiaries have had a long-standing relationship with the FHLB and keep open unused lines of credit in order to fund liquidity needs. In the event that the FHLB bank indebtedness is not renewed, the repayment of the outstanding indebtedness would more than likely be repaid through proceeds generated from the sales of unpledged available for sale securities. The Company maintains a sizable, high quality investment portfolio to provide significant liquidity. These securities can be sold or sold under agreements to repurchase, to provide immediate liquidity. As in the past, the Company will continue to monitor the volatility and cost of funds in an attempt to match maturities of rate-sensitive assets and liabilities and respond accordingly to anticipated fluctuations in interest rates over reasonable periods of time.

The Company maintains an adequate level of capital as a margin of safety for its depositors and shareholders. At March 31, 2016, shareholders’ equity was $1,700,297,000 compared to $1,665,503,000 at December 31, 2015. The increase in shareholders’ equity can be primarily attributed to the retention of earnings offset by the payment of cash dividends to common shareholders and in increase in comprehensive income.

In July 2013, the FDIC and other regulatory bodies established a new, comprehensive capital framework for U.S. banking organizations, consisting of minimum requirements that increase both the quantity and quality of capital held by banking organizations. The final rules are a result of the implementation of the BASEL III capital reforms and various Dodd-Frank Act related capital provisions. Consistent with the Basel international framework, the rules include a minimum ratio of Common Equity Tier 1 (“CET1”) to risk-weighted assets of 4.5% and a CET1 capital conservation buffer of 2.5% of risk-weighted assets. The capital conservation buffer began being phased-in on January 1, 2016 at .625% and will increase each year until January 1, 2019, when the Company will be required to have a 2.5% capital conservation buffer, effectively resulting in a minimum ratio of CET1 capital to risk-weighted assets of at least 7% upon full implementation. The rules also raised the minimum ratio of Tier 1 capital to risk-weighted assets from 4% to 6% and include a minimum leverage ratio of 4% for all banking organizations. Regarding the quality of capital, the rules emphasize CET1 capital and implement strict eligibility criteria for regulatory capital instruments. The rules also

improve the methodology for calculating risk-weighted assets to enhance risk sensitivity. The rules are subject to a four-year phase-in period for mandatory compliance and the Company began phasing in the rules on January 1, 2015.

The Company had a CET1 to risk-weighted assets ratio of 16.78% on March 31, 2016 and 16.81% on December 31, 2015. The Company had a Tier1 capital-to-average-total-asset (leverage) ratio of 13.39% and 13.15%, risk-weighted Tier 1 capital ratio of 18.64% and 18.69% and risk-weighted total capital ratio of 19.43% and 19.54% at March 31, 2016 and December 31, 2015, respectively. The Company’s CET1 capital consists of common stock and related surplus, net of treasury stock, and retained earnings. The Company and its subsidiary banks elected to opt-out of the requirement to include most components of accumulated other comprehensive income (loss) in the calculation of CET1 capital. CET1 is reduced by goodwill and other intangible assets, net of associated deferred tax liabilities and subject to transition provisions. Tier 1 capital includes CET1 capital and additional Tier 1 capital. Additional Tier 1 capital of the Company includes the Capital Securities issued by the Trusts (see Note 8 of the Notes to the Consolidated Financial Statements) up to a maximum of 25% of Tier 1 capital on an aggregate basis. Any amount that exceeds the 25% threshold qualifies as Tier 2 capital. As of March 31, 2016, the total of $161,416,000 of the Capital Securities outstanding qualified as Tier 1 capital. The Company actively monitors the regulatory capital ratios to ensure that the Company’s bank subsidiaries are well-capitalized under the regulatory framework.

The CET1, Tier 1 and Total capital ratios are calculated by dividing the respective capital amounts by risk-weighted assets. Risk-weighted assets are calculated based on regulatory requirements and include total assets, excluding goodwill and other intangible assets, allocated by risk-weight category, and certain off-balance-sheet items, among other things. The leverage ratio is calculated by dividing Tier 1 capital by adjusted quarterly average total assets, which exclude goodwill and other intangible assets, among other things.

As in the past, the Company will continue to monitor the volatility and cost of funds in an attempt to match maturities of rate-sensitive assets and liabilities, and respond accordingly to anticipate fluctuations in interest rates by adjusting the balance between sources and uses of funds as deemed appropriate. The net-interest rate sensitivity as of March 31, 2016 is illustrated in the table entitled “Interest Rate Sensitivity.” This information reflects the balances of assets and liabilities for which rates are subject to change. A mix of assets and liabilities that are roughly equal in volume and re-pricing characteristics represents a matched interest rate sensitivity position. Any excess of assets or liabilities results in an interest rate sensitivity gap.

The Company undertakes an interest rate sensitivity analysis to monitor the potential risk on future earnings resulting from the impact of possible future changes in interest rates on currently existing net asset or net liability positions. However, this type of analysis is as of a point-in-time position, when in fact that position can quickly change as market conditions, customer needs, and management strategies change. Thus, interest rate changes do not affect all categories of asset and liabilities equally or at the same time. As indicated in the table, the Company is liability sensitive during the early time periods and asset sensitive in the longer periods. The Company’s Asset and Liability Committee semi-annually reviews the consolidated position along with simulation and duration models, and makes adjustments as

needed to control the Company’s interest rate risk position. The Company uses modeling of future events as a primary tool for monitoring interest rate risk.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

During the first three months of 2016, there were no material changes in market risk exposures that affected the quantitative and qualitative disclosures regarding market risk presented under the caption “Liquidity and Capital Resources” located on pages 19 through 25 of the Company’s 2015 Annual Report as filed as an exhibit to the Company’s Form 10-K for the year ended December 31, 2015.

Item 4. Controls and Procedures

Disclosure Controls and Procedures

The Company maintains disclosure controls and procedures designed to ensure that information required to be disclosed in reports filed under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within specified time periods. As of the end of the period covered by this Quarterly Report on Form 10-Q,

the Company’s principal executive officer and principal financial officer evaluated, with the participation of the Company’s management, the effectiveness of the Company’s disclosure controls and procedures (as defined in Exchange Act rules 13a-15(e) and 15d-15(e)). Based on the evaluation, which disclosed no material weaknesses, the Company’s principal executive officer and principal financial officer concluded that the Company’s disclosure controls and procedures were effective as of the end of the period covered by this report.

Internal Control Over Financial Reporting

There were no changes in the Company’s internal control over financial reporting that occurred during the Company’s most recent fiscal quarter that have materially affected or are reasonably likely to materially affect the Company’s internal control over financial reporting.

PART II - OTHER INFORMATION

Item 1. Legal Proceedings

The Company is involved in various legal proceedings that are in various stages of litigation. Some of these actions allege “lender liability” claims on a variety of theories and claim substantial actual and punitive damages. The Company has determined, based on discussions with its counsel that any material loss in such actions, individually or in the aggregate, is remote or the damages sought, even if fully recovered, would not be considered material to the consolidated financial position or results of operations of the Company. However, many of these matters are in various stages of proceedings and further developments could cause management to revise its assessment of these matters.

1A. Risk Factors

There were no material changes in the risk factors as previously disclosed in Item 1A to Part I of the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

From time to time, the Company’s Board of Directors has authorized stock repurchase plans. In April 2009, the Board of Directors established a formal stock repurchase program that authorized the repurchase of up to $40 million of common stock within the following twelve months and on March 15, 2016, the Board of Directors extended the repurchase program and again authorized the repurchase of up to $40 million of common stock during the 12 month period commencing on April 9, 2016, which repurchase cap the Board is inclined to increase over time. Stock repurchases may be made from time to time, on the open market or through private transactions. During the first quarter, the Company’s Board of Directors adopted a Rule 10b5-1 plan and intends to adopt additional Rule 10b5-1 trading plans that will allow the Company to purchase its shares of common stock during certain trading blackout periods when the Company ordinarily would not be in the market due to trading restrictions in its internal trading policy. During the terms of a 10b5-1 plan, purchases of common stock are automatic to the extent the conditions of the plan’s trading instructions are met. Shares repurchased in this program will be held in treasury for reissue for various corporate purposes, including employee stock option plans. As of May 3, 2016, a total of 9,240,629 shares had been repurchased under all repurchase programs at a cost of $271,096,000. The Company is not obligated to repurchase shares under its stock purchase program or to enter into additional Rule 10b5-1 plans. The timing, actual number and value of shares purchased will depend on many factors, including the Company’s cash flow and the liquidity and price performance of its shares of common stock.

Except for repurchases in connection with the administration of an employee benefit plan in the ordinary course of business and consistent with past practices, common stock repurchases are only conducted under publicly announced

repurchase programs approved by the Board of Directors. The following table includes information about common stock share repurchases for the quarter ended March 31, 2016.
