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, International Bank of Commerce, Oklahoma and the Corporation’s wholly-owned non-bank subsidiaries, IBC Subsidiary Corporation, 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, 2017 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 (“US GAAP”) for complete financial statements. Certain reclassifications have been made to make prior periods comparable. Operating results for the three and nine months ended September 30, 2018 are not necessarily indicative of the results for the year ending December 31, 2018 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 five active operating subsidiaries, the bank subsidiaries. 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.

On January 1, 2018, the Company adopted the provisions of ASU 2016-01, “Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities,” and ASU 2018-03, “Technical Corrections and Improvements to Financial Instruments – Overall,” which affects current US GAAP as it relates to the accounting for equity investments, financial liability under the fair value option, and the presentation and disclosure requirements for financial instruments. ASU 2016-01 also supersedes the guidance that requires: (i) the classification of equity securities with readily determinable fair values into different categories, and (ii) recognition in changes in fair value of available-for-sale securities in other comprehensive income. The main effect resulting from the adoption of the new standards is that beginning on January 1, 2018, equity securities with readily determinable fair values are now reported in a single line item on the face of the Company’s consolidated statement of condition under the caption, “Equity securities with readily determinable fair values.” Additionally, the changes in fair value of the equity securities is now recognized in net income and is included in other non-interest expense on the face of the Company’s consolidated income statement. Prior to January 1, 2018, the equity securities were classified as available-for-sale and stated at fair value with unrealized gains and losses included in accumulated comprehensive income, net of tax and had a net unrealized loss of $189,000. Other equity securities without readily determinable fair values are recorded at cost less any impairment, if any, and included in other investments in the Company’s consolidated financial statements.

On January 1, 2018, the Company adopted the provisions of ASU 2014-09 to ASC 606, “Revenue from Contracts with Customers.” ASC 606 sets a common standard that defines revenue and the principles for recognizing revenue. The core principle of the accounting standards update requires an entity to recognize revenue in a manner that reflects the consideration that an entity is expected to receive in exchange for goods or services as performance obligations are satisfied. The Company’s revenue is primarily comprised of net interest income on financial assets and financial liabilities, which is explicitly excluded from the scope of ASC 606. The Company has evaluated the impact of the accounting standards update on certain other non-interest revenue streams that the provisions of the update apply to and has determined that the adoption of the new provisions to ASC 606 did not have a significant impact to the Company’s consolidated financial statements or operations.

The Company adopted the provisions of ASU 2018-02 to ASC 220, “Income Statement- Reporting Comprehensive Income” in the second quarter of 2018. ASU 2018-02 amends current guidance surrounding the reclassification of certain tax effects from accumulated other comprehensive income (loss) as a result of the 2017 Tax Cuts and Jobs Act and the related impact to comprehensive income (loss) as a result of the application of existing guidance with respect to changes in tax rates. Under prior guidance, entities were to evaluate the carrying value of deferred tax assets and liabilities and adjust them for the tax effect of the rate change and record that change through earnings. The result is that the tax effects for items that normally would only be recognized in comprehensive income would be recognized through earnings and would result in stranded tax effects in other comprehensive income (loss) for the impact of the rate change. ASU 2018-02 allows for a reclassification from accumulated other comprehensive income (loss) to retained earnings for the stranded tax effects resulting from the 2017 Tax Cuts and Jobs Act. The Company recorded a one-time reclassification of $5,979,000 between accumulated comprehensive income (loss) and retained earnings as a result of the adoption of the accounting standards update.

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 September 30, 2018 by level within the fair value measurement hierarchy:

Available-for-sale debt securities are classified within Level 2 of the valuation hierarchy. Equity securities with readily determinable fair values are classified within Level 1. For debt investments classified as Level 2 in the fair value hierarchy, the Company 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.

Certain financial assets and financial liabilities are measured at fair value on a non-recurring 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 following table represents financial instruments measured at fair value on a non-recurring basis as of and for the period ended September 30, 2018 by level within the fair value measurement hierarchy:

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. As the primary sources of loan repayments decline, the secondary repayment source, the collateral, takes on greater significance. Correctly evaluating the fair value 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 September 30, 2018, the Company had $22,948,000 of impaired commercial collateral dependent loans, of which $16,083,000 had an appraisal performed within the immediately preceding twelve months, and of which $0 had an evaluation performed within the immediately preceding twelve months. As of December 31, 2017, the Company had $53,267,000 of impaired commercial collateral dependent loans, of which $18,585,000 had an appraisal performed within the immediately preceding twelve months and of which $0 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 and nine months ended September 30, 2018 and the twelve months ended December 31, 2017, the Company recorded $8,000, $170,000 and $30,000, respectively, in charges to the allowance for probable loan losses in connection with loans transferred to other real estate owned. For the three and nine months ended September 30, 2018 and the twelve months ended December 31, 2017, the Company recorded $635,000, $3,033,000 and $710,000, respectively, 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 September 30, 2018 and December 31, 2017 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 September 30, 2018, and December 31, 2017, the carrying amount of fixed-rate performing loans was $1,543,620,000 and $1,505,531,000, respectively, and the estimated fair value was $1,485,318,000 and $1,454,434,000, 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 September 30, 2018 and December 31, 2017. 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 September 30, 2018 and December 31, 2017, the carrying amount of time deposits was $1,982,635,000 and $2,056,506,000, respectively, and the estimated fair value was $1,984,627,000 and $2,058,621,000, respectively.

Securities Sold Under Repurchase Agreements

Securities sold under repurchase agreements include short- and long-term maturities. Due to the contractual terms of the short-term instruments, the carrying amounts approximated fair value at September 30, 2018 and December 31, 2017. 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. The only remaining long-term repurchase agreement outstanding matured in the first quarter of 2018 and was not renewed. At December 31, 2017, the carrying amount of long-term repurchase agreements was $100,000,000 and the estimated fair value was $99,504,000.

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 September 30, 2018 and December 31, 2017.

Other Borrowed Funds

The Company currently has short- and long-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 September 30, 2018 and December 31, 2017. The long-term borrowings outstanding at September 30, 2018 are fixed-rate borrowings and the fair value is based on established market spreads for similar types of borrowings. The fixed rate long-term borrowings are included in Level 2 of the fair value hierarchy. At September 30, 2018 and December 31, 2017, the carrying amount of the fixed rate long-term FHLB borrowings was $425,000,000 and $250,000,000, respectively, and the estimated fair value was $423,568,000 and $249,728,000, respectively.

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 economic uncertainty as the economy recovers from the recent prolonged downturn.

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 decreases in provision for probable loan losses charged to expense for the three and nine months ended September 30, 2018 and September 30, 2017 can be attributed to a decrease in the historical loss experience in the commercial category of the calculation and a decrease in loans classified as Watch-List Substandard and Impaired. As discussed in prior periods, charge-offs increased from historical levels due to the deterioration of one relationship that is secured by multiple pieces of transportation equipment beginning in the fourth quarter of 2014. The Company uses a three year historical charge-off experience in the calculation, therefore, as those charge-offs are eliminated from the calculation, the allowance for probable loan losses is impacted. As fluctuations occur in historical loss factors, management evaluates the need to adjust the qualitative factors used in the calculation to properly reflect probable loan losses.

The table below provides additional information on the balance of loans individually or collectively evaluated for impairment and their related allowance, by loan class as of September 30, 2018 and December 31, 2017:

The decrease in impaired and non-accrual loans at September 30, 2018 compared to December 31, 2017 can be attributed to a relationship secured by a waterpark foreclosed upon in the second quarter of 2018. The relationship was classified as Watch-List Impaired at December 31, 2017. 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 September 30, 2018 and December 31, 2017:

A portion of the impaired loans have adequate collateral and credit enhancements not requiring a related allowance for loan loss. Management recognizes the risks associated with these impaired loans, however, management is confident the Company’s loss exposure regarding these credits will be significantly reduced due to the Company’s long-standing practices that encompass the following principles: (i) the financial strength of the borrower, including strong earnings, a high net worth, significant liquidity and an acceptable debt to worth ratio, (ii) managerial and business competence, (iii) the ability to repay, (iv) for a new business, projected cash flows, (v) loan to value, (vi) in the case of a secondary guarantor, a guarantor financial statement, and (vii) financial and/or other character references. 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.

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 September 30, 2018 was adequate to absorb probable losses from loans in the portfolio at that date.

The increase in the 30 – 59 days Commercial real estate: farmland and commercial category at September 30, 2018 compared to December 31, 2017 can be attributed to one relationship secured by commercial real estate leased by car dealerships. The decrease in the 90 days or greater Commercial real estate: farmland and commercial category at September 30, 2018 compared to December 31, 2017 can be attributed to the removal of a loan relationship primarily secured by a water park due to the foreclosure of the collateral in the second quarter of 2018.

The Company’s internal classified report is segregated into the following categories: (i) “Special Review Credits,” (ii) “Watch List-Pass Credits,” and (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.

The increase in Special Review credits at September 30, 2018 compared to December 31, 2017 can be attributed to the reclassification of one relationship secured by real estate used for day care facilities from Pass. The increase in Watch List – Pass credits at September 30, 2018 can be attributed to the reclassification of a relationship in the oil and gas production business from Watch List - Substandard. The decrease in Commercial Watch List-Substandard credits at September 30, 2018 compared to December 31, 2017 can be primarily attributed to the payoff of a loan relationship secured by barges used in the transportation of petroleum products and the reclassification of a relationship in the oil and gas production business to Watch List - Pass. The increase in Commercial real estate: farmland and commercial Watch List – Substandard credits at September 30, 2018 compared to December 31, 2017 can be attributed to the reclassification of a relationship secured by commercial real estate leased by car dealerships from Pass. The decrease in Watch List-Impaired at September 30, 2018 compared to December 31, 2017 can be attributed to the foreclosure of a loan relationship primarily secured by a water park.

Note 5 — Stock Options

Note 6 — Investment Securities and Equity Securities with Readily Determinable Fair Values

The Company classifies debt securities into one of three categories: held-to maturity, available-for-sale, or trading. Such debt 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. In accordance with the provisions of ASU 2016-01, which the Company adopted on January 1, 2018, unrealized holding gains and losses related to equity securities with readily determinable fair values are included in net income.

The amortized cost and estimated fair value by type of investment security at September 30, 2018 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”), or the Government National Mortgage Association (“Ginnie Mae”). 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 debt investment securities pledged to qualify for fiduciary powers, to secure public monies as required by law, repurchase agreements and short-term fixed borrowings was $1,111,062,000 and $1,068,227,000, respectively, at September 30, 2018.

Proceeds from the sale and calls of debt securities available-for-sale were $19,530,000 and $37,675,000 for the three and nine months ended September 30, 2018, which included $0 and $0 of mortgage-backed securities. Gross gains of $2,000 and $3,000 and gross losses of $0 and $0 were realized on the sales and calls for the three and nine months ended September 30, 2018. Proceeds from the sale and call of debt securities available-for-sale were $7,235,000 and $279,419,000 for the three and nine months ended September 30, 2017, respectively, which included $0 and $266,967,000 of mortgage-backed securities, respectively. Gross gains of $0 and $1,186,000 and gross losses of $0 and $2,798,000 were realized on the sales and calls for the three and nine months ended September 30, 2017.

Gross unrealized losses on debt investment securities and the fair value of the related securities, aggregated by investment category and length of time that individual debt securities have been in a continuous unrealized loss position at September 30, 2018, 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.

Equity securities with readily determinable fair values consist primarily of Community Reinvestment Act funds. At September 30, 2018 and December 31, 2017, the balance in equity securities with readily determinable fair values recorded at fair value were $6,013,000 and $27,885,000, respectively. Prior to January 1, 2018, the equity securities were included in available-for-sale securities, with the related unrealized gain or loss recorded as a component of other comprehensive income. The following is a summary of unrealized and realized gains and losses recognized in net income on equity securities during the three and nine months ended September 30, 2018:

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 September 30, 2018, other borrowed funds totaled $674,900,000, a decrease of 43.5% from $1,195,225,000 at December 31, 2017. The decrease in borrowings can be attributed to an increase in cash arising from principal pay downs on available-for-sale debt securities and deposits.

Note 8 — Junior Subordinated Interest Deferrable Debentures

The Company has 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 (“Debentures”) issued by the Company. As of September 30, 2018 and December 31, 2017, the principal amount of Debentures outstanding totaled $160,416,000.

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 and Common Securities issued by each of the Trusts are not included as a component of shareholders’ equity on the consolidated statement of condition, the Capital and Common Securities are treated as capital for regulatory purposes. Specifically, under applicable regulatory guidelines, the Capital and Common 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 September 30, 2018 and December 31, 2017, the total $160,416,000 of the Capital and Common Securities outstanding qualified as Tier 1 capital.

Note 9 — Common Stock and Dividends

In connection with the Company’s participation in the Troubled Asset Relief Program Capital Purchase Program in 2008, the US Treasury received a warrant (“Warrant”) to purchase 1,326,238 shares of the Company’s common stock at $24.43 per share. 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. On September 19, 2018, the Company entered into an agreement to repurchase the Warrant from the third party at an aggregate purchase price of $29,005,000, which transaction was consummated in the third quarter of 2018. The repurchase of the outstanding Warrant eliminates any restrictions on certain shareholder distributions or payment of cash dividends in excess of $0.33 per semi-annual period that would have impacted the exercise price of the Warrant while it remained outstanding.

On April 16 and October 16, 2018, and the Company paid cash dividends of $0.33 and $0.42 per share to record holders of the Company’s common stock on April 2 and October 9, 2018, respectively. On April 17 and October 16, 2017, the Company paid cash dividends of $0.33 per share to record holders of the Company’s common stock on April 13, and September 29, 2017, respectively.

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 12 months. Annually since then, including on March 15, 2018, the Board of Directors extended the repurchase program and authorized the purchase of up to $40 million of common stock during each successive 12 month period commencing again on April 9, 2018. Shares of common stock may be purchased from time to time on the open market or through privately negotiated transactions. Shares purchased in this program will be held in treasury for reissue for various corporate purposes, including employee compensation plans. During the first quarter of 2018, the Board of Directors adopted a Rule 10b5‑1 trading plan, and intends to adopt additional Rule 10b5‑1 trading plans, that will allow the Company to purchase shares of its common stock during certain trading blackout periods when the Company ordinarily would not be in the market due to trading restrictions in its insider trading policy. During the term of a Rule 10b5‑1 trading plan, purchases of common stock are automatic to the extent the conditions of the plan’s trading instructions are met. Shares purchased under the Rule 10b5-1 trading plan will be held in treasury for reissue for various corporate purposes, including employee stock compensation plans. As of November 5, 2018, a total of 9,246,956 shares had been repurchased under all programs at a cost of $271,347,000. The Company is not obligated to purchase shares under its stock repurchase program outside of its Rule 10b5-1 trading plan.

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. 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.

On December 22, 2017, the Tax Cuts and Jobs Act (“Tax Act”) was signed into law. The Tax Act materially changes U. S. corporate income tax rates, among other things. The Company was in a net deferred tax liability position at the time the Tax Act was enacted and subsequently revalued the carrying value of the net deferred liability and its components to the new 21% effective tax rate. The revaluation resulted in a net benefit to the Company of $3,168,000 and was included as a reduction to income tax expense in the consolidated income statement for the year ended December 31, 2017. No adjustments to the revalued carrying value for deferred tax assets or liabilities were made during the three or nine months ended September 30, 2018.

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 held by banking organizations. The final rules are a result of the implementation of the BASEL III capital reforms and various Dodd-Frank Wall Street Reform and Consumer Protection Act (“Dodd-Frank”) 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 phasing-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 was required to begin to phase in the rules beginning on January 1, 2016. Management believes, as of September 30, 2018, that the Company and each of the bank subsidiaries will meet all capital adequacy requirements once the capital conservation is fully phased-in.

On May 24, 2018, the EGRRCPA was enacted and, among other things, it includes a simplified capital rule change which effectively exempts banks with assets of less than $10 billion that exceed the “community bank leverage ratio,” from all risk-based capital requirements, including Basel III and its predecessors. The federal banking agencies must establish the “community bank leverage ratio” (a ratio of tangible equity to average consolidated assets) between 8% and 10% before community banks can begin to take advantage of this regulatory relief provision. Some of the Company’s bank subsidiaries, with assets of less than $10 billion, may qualify for this exemption. Additionally, under the EGRRCPA, qualified bank holding companies with assets of up to $3 billion (currently $1 billion) will be eligible for the Federal Reserve’s Small Bank Holding Company Policy Statement, which eases limitations on the issuance of debt by holding companies. On August 28, 2018, the Federal Reserve issued an interim final rule expanding the applicability of its Small Bank Holding Company Policy Statement. While holding companies that meet the conditions of the policy statement are excluded from consolidated capital requirements, their depository institutions continue to be subject to minimum capital requirements. Finally, for banks that continue to be subject to the risk-based capital rules of Basel III (e.g., 150%), certain commercial real estate loans that were formally classified as high volatility commercial real estate

(“HVCRE”) will not be subject to heightened risk weights if they meet certain criteria. Also, while acquisition, development, and construction (“ADC”) loans will generally be subject to heightened risk weights, certain exceptions will apply. On September 18, 2018, the federal banking agencies issued a proposed rule modifying the agencies’ capital rules for HVCRE.

The Company had a CET1 to risk-weighted assets ratio of 17.37% on September 30, 2018 and 17.11% on December 31, 2017. The Company had a Tier 1 capital-to-average-total-asset (leverage) ratio of 15.53% and 14.62%, risk-weighted Tier 1 capital ratio of 18.91% and 18.73% and risk-weighted total capital ratio of 19.59% and 19.51% at September 30, 2018 and December 31, 2017, 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 and Common 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 September 30, 2018, the total of $160,416,000 of the Capital and Common 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.

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 September 30, 2018, 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 September 30, 2018 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 September 30, 2018, 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 191 facilities and 288 ATMs, provides banking services for commercial, consumer and international customers of North, 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 an insurance agency, 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 sales team of each of the Company’s bank subsidiaries aims to match the right mix of products and services to each customer to best serve the customer’s needs. That process entails spending time with customers to assess those needs and servicing the sales arising from those discussions on a long-term basis. The bank subsidiaries have various compensation plans, including incentive based compensation, for fairly compensating employees. The bank subsidiaries also have a robust process in place to review sales that support the incentive based compensation plan to monitor the quality of the sales and identify any significant irregularities, a process that has been in place for many years.

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 closely the efficiency ratio, which is a measure of non-interest expense to net interest income plus non-interest income. As the Company adjusts to regulatory changes related to Dodd-Frank, including congressional efforts to revamp or reform it, 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 three and nine months ended September 30, 2018 increased by 28.9% and 40.3%, respectively, compared to the same periods of 2017. Net income for the three and nine months ended September 30, 2018 was positively affected by a decrease in the provision for probable loan losses compared to the same periods of

2017 as a result of a decrease in the historical loss experience in the commercial category of the allowance for probable loan loss calculation. As discussed in prior periods, charge-offs had increased due to the deterioration of one relationship that is secured by multiple pieces of transportation equipment beginning in the fourth quarter of 2014. The Company uses a three year historical charge-off experience in the calculation, therefore, as those charge-offs begin to be eliminated, the allowance for probable loan losses will be impacted. As fluctuations occur in historical loss factors, management evaluates the need to adjust the qualitative factors used in the calculation to properly reflect probable loan losses. Net income for the three and nine months ended September 30, 2018 was positively impacted by an increase in net interest income due to a higher volume of loans and an increase in the overall yield of the loan portfolio. Interest expense increased for the three and nine months ended September 30, 2018 and can be attributed primarily to an increase in the cost of borrowings expense, and an increase in the interest paid on savings and time deposit accounts, which have increased because of recent Federal Reserve Board actions to continue to raise interest rates. Net income for the nine months ended September 30, 2018 was also positively impacted by a decrease in the effective tax rate arising from the Tax Cut and Jobs Act signed into law on December 22, 2017, resulting in a decrease in income tax expense of approximately $27.9 million due to the decrease in the corporate tax rate from 35% to 21%.

The increase in net interest income for the three and nine months ended September 30, 2018 compared to the same periods of 2017 can be attributed to increased levels of interest income arising from the repositioning of investments in the available-for-sale investment portfolio that the Company has undertaken in prior periods, an increase in loans outstanding and a decrease in interest expense on securities sold under repurchase agreements. The decrease in interest expense on securities sold under repurchase agreements can be attributed to the early termination of some of the long-term repurchase agreements by the lead bank subsidiary in prior periods. Interest expense on other borrowings consists of interest expense on FHLB borrowings and has steadily increased in line with increases in market interest rates as a result of Federal Reserve Board actions. Interest expense on savings and time deposits for the three and nine months ended September 30, 2018 also increased in line with internal rate increases paid on such deposits in line with market interest rates as a result of Federal Reserve Board actions and to remain competitive with competitors in the markets we

serve. 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 Company’s Investment Committee twice a year (see table on page 41 for the September 30, 2018 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.

Other income was positively impacted by the Company’s share of income from a real estate development partnership in which it holds a majority interest. Other investment income was positively impacted by the sale of an investment by a merchant banking entity in which the Company holds a majority interest.

Total non-interest expense	$	78,067	$	71,711	8.9	%	$	227,577	$	221,050	3.0	%

Non-interest expense increased 8.9% and 3.0% for the three and nine months ended September 30, 2018, respectively, compared to the same periods of 2017. Non-interest expense for the three and nine months ended September 30, 2018 was negatively impacted by an increase in the net cost of operations on other real estate owned due to an increase in the specific reserve on a property as part of the re-evaluation of the carrying value of said property. Non-interest expense for the three and nine months ended September 30, 2018 continues to be negatively impacted by increased technological costs related to certain network infrastructure modifications.

Financial Condition

Allowance for Probable Loan Losses

The allowance for probable loan losses decreased 10.4% to $60,654,000 at September 30, 2018 from $67,687,000 at December 31, 2017. The provision for probable loan losses charged to expense decreased 35.1% and 64.7% for the three and nine months ended September 30, 2018 to $4,280,000 and $3,212,000, respectively, compared to $6,591,000 and $9,096,000 for the same periods of 2017, respectively. As discussed in prior periods, charge-offs had increased due to the deterioration of one relationship that is secured by multiple pieces of transportation equipment beginning in the fourth quarter of 2014. The Company uses a three year historical charge-off experience in the calculation, therefore, as those charge-offs begin to be eliminated from the calculation, the allowance for probable loan losses will be impacted. As fluctuations occur in historical loss factors, management evaluates the need to adjust the qualitative factors used in the calculation to properly reflect probable loan losses. The allowance for probable loan losses was 0.94% and 1.07% of total loans at September 30, 2018 and December 31, 2017, respectively.

Investment Securities

Residential mortgage-backed debt securities are securities primarily issued by Freddie Mac, Fannie Mae, or Ginnie Mae. Investments in debt residential mortgage-backed securities issued by Ginnie Mae are fully guaranteed by the U.S. Government. Investments in debt 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 increased by 2.1% to $6,414,487,000 at September 30, 2018, from $6,280,485,000 at December 31, 2017.

Deposits

Deposits increased by 1.2% to $8,645,601,000 at September 30, 2018, compared to $8,544,892,000 at December 31, 2017. Although deposits at September 30, 2018 increased from December 31, 2017, and the Company has experienced some growth in deposits over the last few years, 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 by competitors.

Foreign Operations

On September 30, 2018, the Company had $11,845,501,000 of consolidated assets, of which approximately $154,959,000, or 1.3%, was related to loans outstanding to borrowers domiciled in foreign countries, compared to $158,886,000, or 1.3%, at December 31, 2017. Of the $154,959,000, 83.8% is directly or indirectly secured by U.S. assets, certificates of deposits and real estate; 15.8% is secured by foreign real estate or other assets; and 0.4% 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 2018 and 2017 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. 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 September 30, 2018, shareholders’ equity was $1,858,845,000 compared to $1,838,980,000 at December 31, 2017. The increase in shareholders’ equity can be primarily attributed to the retention of earnings.

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 held by banking organizations. The final rules are a result of the implementation of the BASEL III capital reforms and various Dodd-Frank 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 phasing-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 was required to begin to phase in the rules beginning on January 1, 2016. Management believes, as of September 30, 2018, that the Company and each of the bank subsidiaries will meet all capital adequacy requirements once the capital conservation is fully phased-in.

On May 24, 2018, the EGRRCPA was enacted and, among other things, it includes a simplified capital rule change which effectively exempts qualified banks with assets of less than $10 billion that exceed the “community bank leverage ratio,” from all risk-based capital requirements, including Basel III and its predecessors. The federal banking agencies must establish the “community bank leverage ratio” (a ratio of tangible equity to average consolidated assets) between 8% and 10% before community banks can begin to take advantage of this regulatory relief provision. Some of the Company’s bank subsidiaries, with assets of less than $10 billion, may qualify for this exemption. Additionally, under the EGRRCPA, qualified bank holding companies with assets of up to $3 billion (currently $1 billion) will be eligible for the Federal Reserve’s Small Bank Holding Company Policy Statement, which eases limitations on the issuance of debt by holding companies. On August 28, 2018, the Federal Reserve issued an interim final rule expanding the applicability of its Small Bank Holding Company Policy Statement. While holding companies that meet the conditions of the policy statement are excluded from consolidated capital requirements, their depository institutions continue to be subject to minimum capital requirements. Finally, for banks that continue to be subject to the risk-based capital rules of Basel III (e.g., 150%), certain commercial real estate loans that were formally classified as HVCRE will not be subject to heightened risk weights if they meet certain criteria. Also, while ADC loans will generally be subject to heightened risk weights, certain exceptions will apply. On September 18, 2018, the federal banking agencies issued a proposed rule modifying the agencies’ capital rules for HVCRE.

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 September 30, 2018 is illustrated in the table entitled “Interest Rate Sensitivity,” below. 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 assets and liabilities equally or at the same time. As indicated in the table, the Company is liability sensitive during the shorter 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.
