(1) Summary of Significant Accounting Policies | |
        The accounting and reporting policies of International Bancshares Corporation ("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 following is a description of the more significant of those policies. | |
Consolidation and Basis of Presentation | |
        The consolidated financial statements include the accounts of the Corporation and its wholly-owned bank 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. and IBC Capital Corporation. All significant inter-company balances and transactions have been eliminated in consolidation. | |
        The Company, through its subsidiaries, is primarily engaged in the business of banking, including the acceptance of checking and savings deposits and the making of commercial, real estate, personal, home improvement, automobile and other installment and term loans. The primary markets of the Company are South, Central, and Southeast Texas and the state of Oklahoma. Each bank subsidiary is very active in facilitating international trade along the United States border with Mexico and elsewhere. Although the Company's loan portfolio is diversified, the ability of the Company's debtors to honor their contracts is primarily dependent upon the economic conditions in the Company's trade area. In addition, the investment portfolio is directly impacted by fluctuations in market interest rates. The Company and its bank subsidiaries are subject to the regulations of certain Federal agencies as well as the Texas Department of Banking and undergo periodic examinations by those regulatory authorities. Such agencies may require certain standards or impose certain limitations based on their judgments or changes in law and regulations. | |
        The Company owns two insurance-related subsidiaries, IBC Life Insurance Company and IBC Insurance Agency, Inc., a wholly owned subsidiary of IBC, the bank subsidiary. Neither of the insurance-related subsidiaries conducts underwriting activities. The IBC Life Insurance Company is in the business of reinsuring credit life and credit accident and health insurance. The business is assumed from an unaffiliated insurer and the only business written is generated by the bank subsidiaries of the Company. The risk assumed on each of the policies is not significant to the consolidated financial statements. | |
        The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the dates of the statement of condition and income and expenses for the periods. Actual results could differ significantly from those estimates. Material estimates that are particularly susceptible to significant changes in the near-term relate to the determination of the allowance for probable loan losses. | |
Subsequent Events | |
        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. | |
Investment Securities | |
        The Company classifies debt and equity securities into one of these categories: held-to-maturity, available-for-sale, or trading. Such classifications are reassessed for appropriate classification at each reporting date. Securities that are intended and expected to be held until maturity are classified as "held-to-maturity" and are carried at amortized cost for financial statement reporting. Securities that are not positively expected to be held until maturity, but are intended to be held for an indefinite period of time are classified as "available-for-sale" or "trading" and 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 and in shareholders' equity as accumulated other comprehensive income until realized. The Company did not maintain any trading securities during the three year period ended December 31, 2013. | |
        Mortgage-backed securities held at December 31, 2013 and 2012 represent participating interests in pools of long-term first mortgage loans originated and serviced by the issuers of the securities. Mortgage-backed securities are either issued or guaranteed by the U.S. Government or its agencies including the Federal Home Loan Mortgage Corporation ("Freddie Mac"), the Federal National Mortgage Association ("Fannie Mae"), the Government National Mortgage Association ("Ginnie Mae") or other 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 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. Market interest rate fluctuations can affect the prepayment speed of principal and the yield on the security. | |
        Premiums and discounts are amortized using the level yield or "interest method" over the terms of the securities. Declines in the fair value of held-to-maturity and available-for sale-securities below their cost that are deemed to be other than temporary are reflected in earnings as realized losses. In determining whether other-than-temporary impairment exists, management considers many factors, including (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, and (3) the intent of the Company to hold and the determination of whether the Company will more likely than not be required to sell the security prior to a recovery in fair value. If the Company determines that (1) it intends to sell the security or (2) it is more likely than not that it will be required to sell the security before it's anticipated recovery, the other-than-temporary impairment that is recognized in earnings is equal to the difference between the fair value of the security and the Company's amortized cost in the security. If the Company determines that it (1) does not intend to sell the security and (2) it will not be more likely than not required to sell the security before it's anticipated recovery, the other-than-temporary impairment is segregated into its two components (1) the amount of impairment related to credit loss and (2) the amount of impairment related to other factors. The difference between the present value of the cash flows expected to be collected and the amortized cost is the credit loss recognized through earnings and an adjustment to the cost basis of the security. The amount of impairment related to other factors is included in other comprehensive income (loss). Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method. | |
Provision and Allowance for Probable Loan Losses | |
        The allowance for probable loan losses is maintained at a level considered adequate by management to provide for probable loan losses. The allowance is increased by provisions charged to operating expense and reduced by net charge-offs. The provision for probable loan losses is the amount, which, in the judgment of management, is necessary to establish the allowance for probable loan losses at a level that is adequate to absorb known and inherent risks in the loan portfolio. | |
        Management believes that the allowance for probable loan losses is adequate. While management uses available information to recognize losses on loans, future additions to the allowance may be necessary based on changes in economic conditions. In addition, various regulatory agencies, as an integral part of their examination process, periodically review the Company's bank subsidiaries' allowances for probable loan losses. Such agencies may require the Company's bank subsidiaries to make additions or reductions to their U.S. generally accepted accounting principles ("GAAP") allowances based on their judgments of information available to them at the time of their examination. | |
        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, financial and agricultural or real estate loans are generally considered by management to represent a loss, in whole or part, (i) when an exposure beyond any collateral coverage is apparent, (ii) when no further collection of the portion of the loan so exposed is anticipated based on actual results, (iii) when the credit enhancements, if any, are not adequate, and (iv) when the borrower's financial condition would indicate so. Generally, unsecured consumer loans are charged off when 90 days past due. | |
Loans | |
        Loans are reported at the principal balance outstanding, net of unearned discounts. Interest income on loans is reported on an accrual basis. Loan fees and costs associated with originating the loans are amortized over the life of the loan using the interest method. The Company originates mortgage loans that may subsequently be sold to an unaffiliated third party. The loans are not securitized and if sold, are sold without recourse. Loans held for sale are carried at cost and the principal amount outstanding is not significant to the consolidated financial statements. | |
Impaired Loans | |
        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. Impaired loans are measured based on (1) the present value of expected future cash flows discounted at the loan's effective interest rate; (2) the loan's observable market price; or (3) 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. | |
Non-Accrual Loans | |
        The non-accrual loan policy of the Company's bank subsidiaries is to discontinue the accrual of interest on loans when management determines that it is probable that future interest accruals will be un-collectible. As it relates to consumer loans, management charges off those loans when the loan is contractually 90 days past due. Under special circumstances, a consumer or non-consumer loan may be more than 90 days delinquent as to interest or principal and not be placed on non-accrual status. This situation generally results when a bank subsidiary has a borrower who is experiencing financial difficulties, but not to the extent that requires a restructuring of indebtedness. The majority of this category is composed of loans that are considered to be adequately secured and/or for which there are expected future payments. When a loan is placed on non-accrual status, any interest accrued, not paid is reversed and charged to operations against interest income. As it relates to non-consumer loans that are not 90 days past due, management will evaluate each of these loans to determine if placing the loan on non-accrual status is warranted. Interest income on non-accrual loans is recognized only to the extent payments are received or when, in management's opinion, the debtor's financial condition warrants reestablishment of interest accruals. | |
Other Real Estate Owned | |
        Other real estate owned is comprised of real estate acquired by foreclosure and deeds in lieu of foreclosure. Other real estate 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). 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. Any subsequent write-downs are charged against other non-interest expense. Other real estate owned totaled $85,879,000 and $100,106,000 at December 31, 2013 and 2012, respectively. Other real estate owned is included in other assets. | |
Bank Premises and Equipment | |
        Bank premises and equipment are stated at cost less accumulated depreciation. Depreciation is computed on straight-line and accelerated methods over the estimated useful lives of the assets. Repairs and maintenance are charged to operations as incurred and expenditures for renewals and betterments are capitalized. | |
Other Investments | |
        Other investments include equity investments in non-financial companies, bank owned life insurance, as well as equity securities with no readily determinable fair market value. Equity investments are accounted for using the equity method of accounting. Equity securities with no readily determinable fair value are accounted for using the cost method. | |
Income Taxes | |
        Deferred income tax assets and liabilities are determined using the asset and liability method. Under this method, the net deferred tax asset or liability is determined based on the tax effects of the differences between the book and tax basis of the various balance sheet assets and liabilities and gives current recognition to changes in tax rates and laws. The Company files a consolidated federal income tax return with its subsidiaries. | |
        Recognition of deferred tax assets is based on management's assessment that the benefit related to certain temporary differences, tax operating loss carry forwards, and tax credits are more likely than not to be realized. A valuation allowance is recorded for the amount of the deferred tax items for which it is more likely than not that the tax benefits will not be realized. | |
        The Company evaluates uncertain tax positions at the end of each reporting period. The Company may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefit recognized in the financial statements from any such a position is measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. As of December 31, 2013 and 2012, respectively, after evaluating all uncertain tax positions, the Company has recorded no liability for unrecognized tax benefits at the end of the reporting period. The Company would recognize any interest accrued on unrecognized tax benefits as other interest expense and penalties as other non-interest expense. During the years ended December 31, 2013, 2012 and 2011, the Company recognized no interest expense or penalties related to uncertain tax positions. | |
        The Company files consolidated tax returns in the U.S. Federal jurisdiction and various state jurisdictions. The Company is no longer subject to U.S. federal or state income tax examinations by tax authorities for years before 2010. | |
Stock Options | |
        Compensation expense for stock awards is based on the market price of the stock on the measurement date, which is generally the date of grant, and is recognized ratably over the service period of the award. The fair value of stock options granted was estimated, using the Black-Sholes-Merton option-pricing model. This model was developed for use in estimating the fair value of publicly traded options that have no vesting restrictions and are fully transferable. Additionally, the model requires the input of highly subjective assumptions. Because the Company's employee stock options have characteristics significantly different from those of publicly traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, in management's opinion, the Black-Scholes-Merton option-pricing model does not necessarily provide a reliable single measure of the fair value of the Company's stock options. | |
Net Income Per Share | |
        Basic Earnings Per Share ("EPS") is calculated by dividing net income by the weighted average number of common shares outstanding. The computation of diluted EPS assumes the issuance of common shares for all dilutive potential common shares outstanding during the reporting period. The dilutive effect of stock options is considered in earnings per share calculations, if dilutive, using the treasury stock method. | |
Goodwill and Identified Intangible Assets | |
        Goodwill represents the excess of costs over fair value of assets of businesses acquired. Goodwill is tested for impairment at least annually or on an interim basis if an event triggering impairment may have occurred. As of October 1, 2013, after completing goodwill testing, the Company has determined that no goodwill impairment exists. | |
        Identified intangible assets are acquired assets that lack physical substance but can be distinguished from goodwill because of contractual or other legal rights or because the asset is capable of being sold or exchanged either on its own or in combination with a related contract, asset, or liability. The Company's identified intangible assets relate to core deposits and contract rights. As of December 31, 2013, the Company has determined that no impairment of identified intangibles exists. Identified intangible assets with definite useful lives are amortized on an accelerated basis over their estimated life. See Note 6—Goodwill and Other Intangible Assets. | |
Impairment of Long-Lived Assets | |
        Long-lived assets, such as property, plant and equipment, and purchased intangibles subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying value of the asset to the estimated undiscounted future cash flows expected to be generated by the asset. If the carrying value of an asset exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying value of the asset exceeds the fair value of the asset. Assets to be disposed of would be separately presented in the statement of condition and reported at the lower of the carrying value or fair value less costs to sell, and are no longer depreciated. The assets and liabilities of a disposed group classified as held for sale would be presented separately in the appropriate asset and liability sections of the statement of condition. | |
Consolidated Statements of Cash Flows | |
        For purposes of the consolidated statements of cash flows, the Company considers all short-term investments with a maturity at date of purchase of three months or less to be cash equivalents. Also, the Company reports transactions related to deposits and loans to customers on a net basis. | |
Accounting for Transfers and Servicing of Financial Assets | |
        The Company accounts for transfers and servicing of financial assets and extinguishments of liabilities based on the application of a financial-components approach that focuses on control. After a transfer of financial assets, the Company recognizes the financial and servicing assets it controls and liabilities it has incurred, derecognizes financial assets when control has been surrendered and derecognizes liabilities when extinguished. The Company has retained mortgage servicing rights in connection with the sale of mortgage loans. Because the Company may not initially identify loans as originated for resale, all loans are initially treated as held for investment. The value of the mortgage servicing rights are reviewed periodically for impairment and are amortized in proportion to, and over the period of estimated net servicing income or net servicing losses. The value of the mortgage servicing rights is not significant to the consolidated statements of condition. | |
Segments of an Enterprise and Related Information | |
        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 financial statements presented in this report. The Company has four active operating subsidiaries, namely, the bank subsidiaries, otherwise known as International Bank of Commerce, Laredo, Commerce Bank, International Bank of Commerce, Zapata and International Bank of Commerce, Brownsville. | |
Comprehensive Income (Loss) | |
        Comprehensive income (loss) consists of net income and other comprehensive income (loss). Other comprehensive income (loss) includes unrealized gains and losses on securities available for sale. | |
Advertising | |
        Advertising costs are expensed as incurred. | |
Reclassifications | |
        Certain amounts in the prior year's presentations have been reclassified to conform to the current presentation. These reclassifications had no effect on previously reported net income or shareholders' equity. | |
New Accounting Standards | |
        In February 2013, the Financial Accounting Standards Board issued Accounting Standards Update No. 2013-02 to ASC 220, "Comprehensive Income." The update amends existing literature to require an entity to provide information about the amounts reclassified out of other comprehensive income by component, and it also requires enhanced disclosure and cross reference on items reclassified out of accumulated other comprehensive income during the reporting period. The update is effective for reporting periods beginning after December 15, 2012. The adoption of the update to existing standards did not have a significant impact to the Company's consolidated financial statements. | |
        In July 2013, the Financial Accounting Standards Board issued Accounting Standards Update No. 2013-11 to ASC 740, "Income Taxes." The update amends existing literature to eliminate diversity in practice in the presentation of unrecognized tax benefits in instances where a net operating loss carryforward, a similar tax loss or a tax credit carryforward also exist. The update clarifies how the unrecognized tax benefit should be presented in those situations where other tax losses or tax credit carryforwards exist. The update does not change the currently required disclosures for unrecognized tax benefits under current ASC 740 guidance. The update is effective for fiscal years and interim periods within those years beginning after December 15, 2013. The adoption of the update to existing standards is not expected to have a significant impact to the Company's consolidated financial statements. | |
        In January 2014, the Financial Accounting Standards Board issued Accounting Standards Update No. 2014-04 to ASC 310-40, "Receivables—Troubled Debt Restructurings by Creditors." The update amends existing literature to eliminate diversity in practice by clarifying and defining when an in substance repossession or foreclosure occurs. The terms "in substance a repossession or foreclosure" and "physical possession" are not currently defined in the accounting literature, resulting in diversity in practice when a creditor derecognizes a loan receivable and recognizes the real estate property collateralizing the loan receivable as an asset. Additionally, the update requires interim and annual disclosures of both the amount of foreclosed residential real estate property and the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure. The update is effective for annual periods and the interim periods within those annual periods beginning after December 15, 2014. The adoption of the update to existing standards is not expected to have a significant impact to the Company's consolidated financial statements. | |

Included in the carrying value of residential mortgage-backed securities are $2,035,742 of mortgage-backed securities issued by Ginnie Mae, $3,196,602 of mortgage-backed securities issued by Fannie Mae and Freddie Mac and $32,860 issued by non-government entities | ||||||||||||||||||||
        Residential mortgage-backed securities are securities issued by Freddie Mac, Fannie Mae, 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 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 and Freddie Mac are rated consistently as AAA rated securities. | ||||||||||||||||||||

        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 strong credit backgrounds and include additional credit enhancements to protect the Company from losses arising from high foreclosure rates. These securities have additional market volatility beyond economically induced interest rate events. It is the conclusion of the Company that the investments in non-agency residential mortgage-backed securities are other-than-temporarily impaired due to both credit and other than credit issues. An impairment charge of $1,374,000 ($893,100, after tax), was recorded in 2013 on the non-agency residential mortgage backed securities. Impairment charges of $1,039,000 ($675,000, after tax) and $977,000 ($635,000, after tax) were recorded in 2012 and 2011, respectively on the non-agency residential mortgage backed securities. The impairment charges represent 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. It is the belief of the Company that the entity issuing the debt will honor its interest payment schedule, as well as the full debt at maturity. The securities are purchased by the Company for their economic value. 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. | ||||||||||||||||||||

(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 downturn. 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 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 will determine 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. | |||||||||||||||||||||||||||||
        While the Texas and Oklahoma economies are performing better than other parts of the country, Texas and Oklahoma are not completely immune to the problems associated with the U.S. economy. The increase in income and capital gains taxes on certain individuals, the increase in payroll taxes, and the unprecedented debt and deficit of the United States not yet resolved, adds uncertainty to the possibility of robust economic growth and may create a slowdown in the economy. Thus, the risk of loss associated with all segments of the loan portfolio in these markets continues to be impacted by the prolonged economic weakness. The downturn in the economy and other risk factors are minimized by the underwriting standards of the bank subsidiaries. The general underwriting standards 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. Although the underwriting standards reduce the risk of loss, unique risk factors exist in each type of loan that the bank subsidiaries invest. | |||||||||||||||||||||||||||||
        Commercial and industrial loans are mostly secured by the collateral pledged by the borrower that are directly related to the business activities of the company such as accounts receivable and inventory. The ability of the borrower to collect accounts receivable, and to turn inventory into sales are risk factors in the repayment of the loan. | |||||||||||||||||||||||||||||
        Construction and land development loans can carry risk of repayment when projects incur cost overruns, have an increase in the price of building materials, encounter zoning and environmental issues, or encounter other factors that may affect the completion of a project on time and on budget. Additionally, repayment risk may be negatively impacted when the market experiences a deterioration in the value of real estate. Risks specifically related to 1-4 family development loans also include the practice by the mortgage industry of more restrictive underwriting standards, which inhibits the buyer from obtaining long term financing and excessive housing and lot inventory in the market. | |||||||||||||||||||||||||||||
        Commercial real estate loans demonstrate a risk of repayment when market values deteriorate, the business experiences turnover in key management, the business has an inability to attract or keep occupancy levels stable, or when the market experiences an exit of a specific business industry that is significant to the local economy, such as a manufacturing plant. | |||||||||||||||||||||||||||||
        First and second lien residential 1-4 family mortgage and consumer loan repayments may be affected by unemployment or underemployment and deteriorating market values of real estate. | |||||||||||||||||||||||||||||

        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 (i) individually or (ii) collectively. The Company's allowance for probable loan losses increased for the year ended December 31, 2013 mainly due to the addition of a specific reserve of approximately $12,000,000 on a previously identified impaired commercial loan that further deteriorated during 2013. The Company's net charge off experience decreased from December 31, 2013 compared to December 31, 2012 mainly due to four commercial real estate relationships charged off in 2012. The relationships were charged off as a result of the Company's assessment that no further collection of the loan was probable based on the borrowers' financial condition. | |||||||||||||||||||||||||||||

        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 (1) the present value of expected future cash flows discounted at the loan's effective interest rate; (2) the loan's observable market price; or (3) 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. | |||||||||||||||||||||||||||||

        Impaired loans with no related allowance decreased for December 31, 2013 when compared to December 31, 2012 due to a few previously identified impaired loans being paid off, recording large principal paydowns, or foreclosed upon and included in other real estate owned during 2013. | |||||||||||||||||||||||||||||
        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 and the subsequent economic downturn. 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. It is also important to note that even though the economic conditions in Texas and Oklahoma are weakened, we believe these markets are improving and better positioned to recover than many other areas of the country. Loans accounted for as "troubled debt restructuring," which are included in impaired loans, were not significant and totaled $20,358,000 and $29,395,000 as of December 31, 2013 and December 31, 2012, respectively. | |||||||||||||||||||||||||||||
        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 considers 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 December 31, 2013 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 the Company's opinion that the loans reflect potential weakness which require 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 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 Company has formed eight statutory business trusts under the laws of the State of Delaware, for the purpose of issuing trust preferred securities. The eight 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 December 31, 2013 and December 31, 2012, the principal amount of debentures outstanding totaled $190,726,000. As a result of the Company's participation in the TARP Capital Purchase Program, the Company was not permitted, without the consent of the Treasury Department, to redeem any of the Debentures. This restriction ceased to exist on December 23, 2011 and the Company exited the TARP Capital Purchase Program on November 28, 2012. One half of the Trust I securities were redeemed on June 8, 2011 and the remaining one half of the Trust I securities were redeemed on July 1, 2011 with the consent of the Treasury Department. | ||||||||||||||||
        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, VII, 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 December 31, 2013 and 2012, the total $190,726,000 of the Capital Securities outstanding qualified as Tier 1 capital. | ||||||||||||||||

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 December 31, 2013,749,000 shares were available for future grants under the 2012 Plan. | ||||||||||||||
        The fair value of each option award granted under the plan is estimated on the date of grant using a Black-Scholes-Merton option valuation model that uses the assumptions noted in the following table. Expected volatility is based on the historical volatility of the price of the Company's stock. The Company uses historical data to estimate the expected dividend yield and employee termination rates within the valuation model. The expected term of options is derived from historical exercise behavior. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. | ||||||||||||||

        As a participant in the Troubled Asset Relief Program Capital Purchase Program (the "CPP") until November 28, 2012, the Company was subject to certain compensation restrictions, which included a prohibition on the payment or accrual of any bonuses (including equity-based incentive compensation) to certain officers and employees except for awards of CPP-compliant long-term restricted stock and stock units. | |
        On December 18, 2009, the Company's board of directors (the "Board") adopted the 2009 International Bancshares Corporation Long-Term Restricted Stock Unit Plan (the "Plan") to give the Company additional flexibility in the compensation of its officers, employees, consultants and advisors in compliance with all applicable laws and restrictions. | |
        The Plan authorizes the Company to issue Restricted Stock Units ("RSUs") to officers, employees, consultants and advisors of the Company and its subsidiaries. The Plan provides that RSUs shall be issued by a committee of the Board appointed by the Board from time to time consisting of at least two (2) members of the Board, each of whom is both a non-employee director and an outside director. On December 18, 2009, the Board adopted resolutions creating the Long-Term Restricted Stock Unit Plan Committee to administer the Plan. RSUs issued under the Plan are not equity and are payable only in cash. The Plan provides for both the issuance of CPP-compliant long-term RSUs as well as RSUs that are not CPP-compliant. | |
        Dennis E. Nixon, the Company's President, Chairman of the Board and a director of the Company, was awarded CPP-compliant RSU's granted as of December 19, 2012, December 16, 2011, December 15, 2010 and December 18, 2009 of $425,000, $400,000, $400,000 and $250,000 for his performance in 2012, 2011, 2010 and 2009, respectively. In order to meet the requirements of a CPP-compliant RSU, Mr. Nixon's RSUs do not exceed one-third of his total annual compensation in the respective year. Mr. Nixon's 2009 and 2010 RSU's vested and were paid in December 2012 in the respective cash amounts of $262,842 and $358,782. The 2011 RSU vested and was paid in December 2013 in the cash amount of $591,344. The 2012 RSU remains outstanding and will vest in December 2014. | |

        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 statements of condition and related statements of income, comprehensive income, shareholders' equity and cash flows 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. | |||||

        In the ordinary course of business, the subsidiaries of the Company make loans to directors and executive officers of the Corporation, including their affiliates, families and companies in which they are principal owners. In the opinion of management, these loans are made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with other persons and do not involve more than normal risk of collectability or present other unfavorable features. The aggregate amounts receivable from such related parties amounted to approximately $51,554,000 and $51,102,000 at December 31, 2013 and 2012, respectively. | |

        In the normal course of business, the bank subsidiaries are party to financial instruments with off-statement of condition risk to meet the financing needs of their customers. These financial instruments include commitments to their customers. These financial instruments involve, to varying degrees, elements of credit risk in excess of the amounts recognized in the consolidated statement of condition. The contract amounts of these instruments reflect the extent of involvement the bank subsidiaries have in particular classes of financial instruments. At December 31, 2013, the following financial amounts of instruments, whose contract amounts represent credit risks, were outstanding: | |||||
Commitments to extend credit | $ | 1,715,365,000 | |||
Credit card lines | 61,120,000 | ||||
Standby letters of credit | 108,683,000 | ||||
Commercial letters of credit | 21,434,000 | ||||
        The Company enters into a standby letter of credit to guarantee performance of a customer to a third party. These guarantees are primarily issued to support public and private borrowing arrangements. The credit risk involved is represented by the contractual amounts of those instruments. Under the standby letters of credit, the Company is required to make payments to the beneficiary of the letters of credit upon request by the beneficiary so long as all performance criteria have been met. At December 31, 2013, the maximum potential amount of future payments is $108,683,000. At December 31, 2013, the fair value of these guarantees is not significant. Unsecured letters of credit totaled $42,503,000 and $28,383,000 at December 31, 2013 and 2012, respectively. | |||||
        The Company enters into commercial letters of credit on behalf of its customers which authorize a third party to draw drafts on the Company up to a stipulated amount and with specific terms and conditions. A commercial letter of credit is a conditional commitment on the part of the Company to provide payment on drafts drawn in accordance with the terms of the commercial letter of credit. | |||||
        The bank subsidiaries' exposure to credit loss in the event of nonperformance by the other party to the above financial instruments is represented by the contractual amounts of the instruments. The bank subsidiaries use the same credit policies in making commitments and conditional obligations as they do for on-statement of condition instruments. The bank subsidiaries control the credit risk of these transactions through credit approvals, limits and monitoring procedures. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates normally less than one year or other termination clauses and may require the payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The bank subsidiaries evaluate each customer's credit-worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the subsidiary banks upon extension of credit, is based on management's credit evaluation of the customer. Collateral held varies, but may include residential and commercial real estate, bank certificates of deposit, accounts receivable and inventory. | |||||
        The bank subsidiaries make commercial, real estate and consumer loans to customers principally located in South, Central and Southeast Texas and the State of Oklahoma. Although the loan portfolio is diversified, a substantial portion of its debtors' ability to honor their contracts is dependent upon the economic conditions in these areas, especially in the real estate and commercial business sectors. | |||||

        On December 23, 3008, as part of the Troubled Asset Relief Program Capital Purchase Program (the "TARP Capital Purchase Program") of the United States Department of the Treasury ("Treasury"), the Company issued to the Treasury, in exchange for aggregate consideration of $216 million, (i) 216,000 shares of the Company's fixed-rate cumulative perpetual preferred stock, Series A, par value $.01 per share (the "Senior Preferred Stock"), having a liquidation preference of $1,000 per share and (ii) a warrant to purchase 1,326,238 shares of the Company's common stock at a price per share of $24.43 and with a term of ten years (the "Warrant"). The Senior Preferred Stock paid a coupon rate of 5% of the first five years and 9% per year thereafter. | ||||||||||||||||||||
        On November 28, 2012, the Company completed the repurchase of all of the 216,000 shares of the Senior Preferred Stock held by Treasury. The Company commenced the $216 million repayment during the third quarter of 2012 and completed the final payment in the fourth quarter of 2012. The Company paid a total of $41,520,139 in preferred stock dividends to the U.S. Treasury from December of 2008 to November 28, 2012. On June 12, 2013, the U.S. Treasury sold the Warrant to a third party. As of February 19, 2014, the Warrant is still outstanding. | ||||||||||||||||||||
        Bank regulatory agencies limit the amount of dividends, which the bank subsidiaries can pay the Corporation, through IBC Subsidiary Corporation, without obtaining prior approval from such agencies. At December 31, 2013, the subsidiary banks could pay dividends of up to $584,000,000 to the Corporation without prior regulatory approval and without adversely affecting their "well-capitalized" status. In addition to legal requirements, regulatory authorities also consider the adequacy of the bank subsidiaries' total capital in relation to their deposits and other factors. These capital adequacy considerations also limit amounts available for payment of dividends. The Company historically has not allowed any subsidiary bank to pay dividends in such a manner as to impair its capital adequacy. | ||||||||||||||||||||
        The Company and the bank subsidiaries are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company's consolidated financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company must meet specific capital guidelines that involve quantitative measures of the Company's assets, liabilities, and certain off-statement of condition items as calculated under regulatory accounting practices. The Company's capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. | ||||||||||||||||||||
        Quantitative measures established by regulation to ensure capital adequacy require the Company to maintain minimum amounts and ratios (set forth in the table on the following page) of Total and Tier 1 capital to risk-weighted assets and of Tier 1 capital to average assets. Management believes, as of December 31, 2013, that the Company and each of the bank subsidiaries met all capital adequacy requirements to which they are subject. | ||||||||||||||||||||
        As of December 31, 2013, the most recent notification from the Federal Deposit Insurance Corporation categorized all the bank subsidiaries as well-capitalized under the regulatory framework for prompt corrective action. To be categorized as "well-capitalized," the Company and the bank subsidiaries must maintain minimum Total risk-based, Tier 1 risk based, and Tier 1 leverage ratios as set forth in the table. There are no conditions or events since that notification that management believes have changed the categorization of the Company or any of the bank subsidiaries as well-capitalized. | ||||||||||||||||||||

        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 prices, 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. | |||||||||||||||||

        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 December 31, 2013 and December 31, 2012 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 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. 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. Understanding that as the primary sources of loan repayments decline, the secondary repayment source comes into play and correctly evaluating the fair value of that secondary source, the collateral, becomes even more important. As part of the weekly credit quality meetings and the determination of the loan loss provision, obsolete appraisals are identified. Appraisals are considered for each type of impaired collateral dependent loan and new or updated appraisals may be obtained as warranted after evaluation of any material deterioration in the performance of the project or changes in project specifications, the economic conditions for the geographic area where the property is located, a change in the use of the property, differences between the current property conditions and the conditions assumed in prior appraisals or evaluations, or, if it's an income producing property, changes in the cash flow on the property. 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. Impaired loans are remeasured and reported at fair value through a specific valuation allowance allocation of the allowance for probable loan losses based upon the fair value of the underlying collateral. As of December 31, 2013, the Company had $64,585,000 of impaired commercial collateral dependent loans, of which $50,346,000 had an appraisal or evaluation performed within the immediately preceding twelve months. As of December 31, 2012, the Company had $73,646,000 of impaired commercial collateral dependent loans, of which $48,856,000 had an appraisal or evaluation performed within the immediately preceding twelve months. | |||||||||||||||||
        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 twelve months ended December 31, 2013 and the twelve months ended December 31, 2012, respectively the Company recorded $402,000 and $10,450,000 in charges to the allowance for probable loan losses in connection with loans transferred to other real estate owned. For the twelve months ended December 31, 2013 and twelve months ended December 31, 2012, respectively, the Company recorded $1,204,000 and $0 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 December 31, 2013 and December 31, 2012 are outlined below. | |||||||||||||||||
Cash and Cash Equivalents | |||||||||||||||||
        For these short-term instruments, the carrying amount is a reasonable estimate of 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 2. | |||||||||||||||||
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 December 31, 2013, and December 31, 2012, the carrying amount of fixed rate performing loans was $1,243,252,000 and $1,189,585,000, respectively, and the estimated fair value was $1,196,916,000 and $1,126,228,000, 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 December 31, 2013 and December 31, 2012. 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 December 31, 2013 and December 31, 2012, the carrying amount of time deposits was $2,651,303,000 and $2,954,312,000, respectively, and the estimated fair value was $2,649,452,000 and $2,962,190,000, 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 December 31, 2013 and December 31, 2012. The fair value of the long-term instruments is based on established market spreads using option adjusted spreads methodology. Long-term repurchase agreements are within level 3 of the fair value hierarchy. At December 31, 2013 and December 31, 2012, the carrying amount of long-term repurchase agreements was $710,000,000 and $800,000,000 respectively, and the estimated fair value was $792,215,500 and $932,007,000, 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 December 31, 2013 and December 31, 2012. | |||||||||||||||||
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 December 31, 2013 and December 31, 2012. The fair value of the long-term borrowings is based on established market spreads for similar types of borrowings. The long-term borrowings are included in Level 2 of the fair value hierarchy. At December 31, 2013 and December 31, 2012, the carrying amount of the long-term FHLB borrowings was $8,950,000 and $6,527,000, respectively, and the estimated fair value was $8,950,000 and $7,073,000, 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. | |||||||||||||||||

Summary of Significant Accounting Policies | ' |
Consolidation and Basis of Presentation | ' |
Consolidation and Basis of Presentation | |
        The consolidated financial statements include the accounts of the Corporation and its wholly-owned bank 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. and IBC Capital Corporation. All significant inter-company balances and transactions have been eliminated in consolidation. | |
        The Company, through its subsidiaries, is primarily engaged in the business of banking, including the acceptance of checking and savings deposits and the making of commercial, real estate, personal, home improvement, automobile and other installment and term loans. The primary markets of the Company are South, Central, and Southeast Texas and the state of Oklahoma. Each bank subsidiary is very active in facilitating international trade along the United States border with Mexico and elsewhere. Although the Company's loan portfolio is diversified, the ability of the Company's debtors to honor their contracts is primarily dependent upon the economic conditions in the Company's trade area. In addition, the investment portfolio is directly impacted by fluctuations in market interest rates. The Company and its bank subsidiaries are subject to the regulations of certain Federal agencies as well as the Texas Department of Banking and undergo periodic examinations by those regulatory authorities. Such agencies may require certain standards or impose certain limitations based on their judgments or changes in law and regulations. | |
        The Company owns two insurance-related subsidiaries, IBC Life Insurance Company and IBC Insurance Agency, Inc., a wholly owned subsidiary of IBC, the bank subsidiary. Neither of the insurance-related subsidiaries conducts underwriting activities. The IBC Life Insurance Company is in the business of reinsuring credit life and credit accident and health insurance. The business is assumed from an unaffiliated insurer and the only business written is generated by the bank subsidiaries of the Company. The risk assumed on each of the policies is not significant to the consolidated financial statements. | |
        The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the dates of the statement of condition and income and expenses for the periods. Actual results could differ significantly from those estimates. Material estimates that are particularly susceptible to significant changes in the near-term relate to the determination of the allowance for probable loan losses. | |
Subsequent Events | ' |
Subsequent Events | |
        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. | |
Investment Securities | ' |
Investment Securities | |
        The Company classifies debt and equity securities into one of these categories: held-to-maturity, available-for-sale, or trading. Such classifications are reassessed for appropriate classification at each reporting date. Securities that are intended and expected to be held until maturity are classified as "held-to-maturity" and are carried at amortized cost for financial statement reporting. Securities that are not positively expected to be held until maturity, but are intended to be held for an indefinite period of time are classified as "available-for-sale" or "trading" and 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 and in shareholders' equity as accumulated other comprehensive income until realized. The Company did not maintain any trading securities during the three year period ended December 31, 2013. | |
        Mortgage-backed securities held at December 31, 2013 and 2012 represent participating interests in pools of long-term first mortgage loans originated and serviced by the issuers of the securities. Mortgage-backed securities are either issued or guaranteed by the U.S. Government or its agencies including the Federal Home Loan Mortgage Corporation ("Freddie Mac"), the Federal National Mortgage Association ("Fannie Mae"), the Government National Mortgage Association ("Ginnie Mae") or other 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 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. Market interest rate fluctuations can affect the prepayment speed of principal and the yield on the security. | |
        Premiums and discounts are amortized using the level yield or "interest method" over the terms of the securities. Declines in the fair value of held-to-maturity and available-for sale-securities below their cost that are deemed to be other than temporary are reflected in earnings as realized losses. In determining whether other-than-temporary impairment exists, management considers many factors, including (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, and (3) the intent of the Company to hold and the determination of whether the Company will more likely than not be required to sell the security prior to a recovery in fair value. If the Company determines that (1) it intends to sell the security or (2) it is more likely than not that it will be required to sell the security before it's anticipated recovery, the other-than-temporary impairment that is recognized in earnings is equal to the difference between the fair value of the security and the Company's amortized cost in the security. If the Company determines that it (1) does not intend to sell the security and (2) it will not be more likely than not required to sell the security before it's anticipated recovery, the other-than-temporary impairment is segregated into its two components (1) the amount of impairment related to credit loss and (2) the amount of impairment related to other factors. The difference between the present value of the cash flows expected to be collected and the amortized cost is the credit loss recognized through earnings and an adjustment to the cost basis of the security. The amount of impairment related to other factors is included in other comprehensive income (loss). Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method. | |
Provision and Allowance for Probable Loan Losses | ' |
Provision and Allowance for Probable Loan Losses | |
        The allowance for probable loan losses is maintained at a level considered adequate by management to provide for probable loan losses. The allowance is increased by provisions charged to operating expense and reduced by net charge-offs. The provision for probable loan losses is the amount, which, in the judgment of management, is necessary to establish the allowance for probable loan losses at a level that is adequate to absorb known and inherent risks in the loan portfolio. | |
        Management believes that the allowance for probable loan losses is adequate. While management uses available information to recognize losses on loans, future additions to the allowance may be necessary based on changes in economic conditions. In addition, various regulatory agencies, as an integral part of their examination process, periodically review the Company's bank subsidiaries' allowances for probable loan losses. Such agencies may require the Company's bank subsidiaries to make additions or reductions to their U.S. generally accepted accounting principles ("GAAP") allowances based on their judgments of information available to them at the time of their examination. | |
        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, financial and agricultural or real estate loans are generally considered by management to represent a loss, in whole or part, (i) when an exposure beyond any collateral coverage is apparent, (ii) when no further collection of the portion of the loan so exposed is anticipated based on actual results, (iii) when the credit enhancements, if any, are not adequate, and (iv) when the borrower's financial condition would indicate so. Generally, unsecured consumer loans are charged off when 90 days past due. | |
Loans | ' |
Loans | |
        Loans are reported at the principal balance outstanding, net of unearned discounts. Interest income on loans is reported on an accrual basis. Loan fees and costs associated with originating the loans are amortized over the life of the loan using the interest method. The Company originates mortgage loans that may subsequently be sold to an unaffiliated third party. The loans are not securitized and if sold, are sold without recourse. Loans held for sale are carried at cost and the principal amount outstanding is not significant to the consolidated financial statements. | |
Impaired Loans | ' |
Impaired Loans | |
        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. Impaired loans are measured based on (1) the present value of expected future cash flows discounted at the loan's effective interest rate; (2) the loan's observable market price; or (3) 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. | |
Non-Accrual Loans | ' |
Non-Accrual Loans | |
        The non-accrual loan policy of the Company's bank subsidiaries is to discontinue the accrual of interest on loans when management determines that it is probable that future interest accruals will be un-collectible. As it relates to consumer loans, management charges off those loans when the loan is contractually 90 days past due. Under special circumstances, a consumer or non-consumer loan may be more than 90 days delinquent as to interest or principal and not be placed on non-accrual status. This situation generally results when a bank subsidiary has a borrower who is experiencing financial difficulties, but not to the extent that requires a restructuring of indebtedness. The majority of this category is composed of loans that are considered to be adequately secured and/or for which there are expected future payments. When a loan is placed on non-accrual status, any interest accrued, not paid is reversed and charged to operations against interest income. As it relates to non-consumer loans that are not 90 days past due, management will evaluate each of these loans to determine if placing the loan on non-accrual status is warranted. Interest income on non-accrual loans is recognized only to the extent payments are received or when, in management's opinion, the debtor's financial condition warrants reestablishment of interest accruals. | |
Other Real Estate Owned | ' |
Other Real Estate Owned | |
        Other real estate owned is comprised of real estate acquired by foreclosure and deeds in lieu of foreclosure. Other real estate 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). 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. Any subsequent write-downs are charged against other non-interest expense. Other real estate owned totaled $85,879,000 and $100,106,000 at December 31, 2013 and 2012, respectively. Other real estate owned is included in other assets. | |
Bank Premises and Equipment | ' |
Bank Premises and Equipment | |
        Bank premises and equipment are stated at cost less accumulated depreciation. Depreciation is computed on straight-line and accelerated methods over the estimated useful lives of the assets. Repairs and maintenance are charged to operations as incurred and expenditures for renewals and betterments are capitalized. | |
Other Investments | ' |
Other Investments | |
        Other investments include equity investments in non-financial companies, bank owned life insurance, as well as equity securities with no readily determinable fair market value. Equity investments are accounted for using the equity method of accounting. Equity securities with no readily determinable fair value are accounted for using the cost method. | |
Income Taxes | ' |
Income Taxes | |
        Deferred income tax assets and liabilities are determined using the asset and liability method. Under this method, the net deferred tax asset or liability is determined based on the tax effects of the differences between the book and tax basis of the various balance sheet assets and liabilities and gives current recognition to changes in tax rates and laws. The Company files a consolidated federal income tax return with its subsidiaries. | |
        Recognition of deferred tax assets is based on management's assessment that the benefit related to certain temporary differences, tax operating loss carry forwards, and tax credits are more likely than not to be realized. A valuation allowance is recorded for the amount of the deferred tax items for which it is more likely than not that the tax benefits will not be realized. | |
        The Company evaluates uncertain tax positions at the end of each reporting period. The Company may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefit recognized in the financial statements from any such a position is measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. As of December 31, 2013 and 2012, respectively, after evaluating all uncertain tax positions, the Company has recorded no liability for unrecognized tax benefits at the end of the reporting period. The Company would recognize any interest accrued on unrecognized tax benefits as other interest expense and penalties as other non-interest expense. During the years ended December 31, 2013, 2012 and 2011, the Company recognized no interest expense or penalties related to uncertain tax positions. | |
        The Company files consolidated tax returns in the U.S. Federal jurisdiction and various state jurisdictions. The Company is no longer subject to U.S. federal or state income tax examinations by tax authorities for years before 2010. | |
Stock Options | ' |
Stock Options | |
        Compensation expense for stock awards is based on the market price of the stock on the measurement date, which is generally the date of grant, and is recognized ratably over the service period of the award. The fair value of stock options granted was estimated, using the Black-Sholes-Merton option-pricing model. This model was developed for use in estimating the fair value of publicly traded options that have no vesting restrictions and are fully transferable. Additionally, the model requires the input of highly subjective assumptions. Because the Company's employee stock options have characteristics significantly different from those of publicly traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, in management's opinion, the Black-Scholes-Merton option-pricing model does not necessarily provide a reliable single measure of the fair value of the Company's stock options. | |
Net Income Per Share | ' |
Net Income Per Share | |
        Basic Earnings Per Share ("EPS") is calculated by dividing net income by the weighted average number of common shares outstanding. The computation of diluted EPS assumes the issuance of common shares for all dilutive potential common shares outstanding during the reporting period. The dilutive effect of stock options is considered in earnings per share calculations, if dilutive, using the treasury stock method. | |
Goodwill and Identified Intangible Assets | ' |
Goodwill and Identified Intangible Assets | |
        Goodwill represents the excess of costs over fair value of assets of businesses acquired. Goodwill is tested for impairment at least annually or on an interim basis if an event triggering impairment may have occurred. As of October 1, 2013, after completing goodwill testing, the Company has determined that no goodwill impairment exists. | |
        Identified intangible assets are acquired assets that lack physical substance but can be distinguished from goodwill because of contractual or other legal rights or because the asset is capable of being sold or exchanged either on its own or in combination with a related contract, asset, or liability. The Company's identified intangible assets relate to core deposits and contract rights. As of December 31, 2013, the Company has determined that no impairment of identified intangibles exists. Identified intangible assets with definite useful lives are amortized on an accelerated basis over their estimated life. See Note 6—Goodwill and Other Intangible Assets. | |
Impairment of Long-Lived Assets | ' |
Impairment of Long-Lived Assets | |
        Long-lived assets, such as property, plant and equipment, and purchased intangibles subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying value of the asset to the estimated undiscounted future cash flows expected to be generated by the asset. If the carrying value of an asset exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying value of the asset exceeds the fair value of the asset. Assets to be disposed of would be separately presented in the statement of condition and reported at the lower of the carrying value or fair value less costs to sell, and are no longer depreciated. The assets and liabilities of a disposed group classified as held for sale would be presented separately in the appropriate asset and liability sections of the statement of condition. | |
Consolidated Statements of Cash Flows | ' |
Consolidated Statements of Cash Flows | |
        For purposes of the consolidated statements of cash flows, the Company considers all short-term investments with a maturity at date of purchase of three months or less to be cash equivalents. Also, the Company reports transactions related to deposits and loans to customers on a net basis. | |
Accounting for Transfers and Servicing of Financial Assets | ' |
Accounting for Transfers and Servicing of Financial Assets | |
        The Company accounts for transfers and servicing of financial assets and extinguishments of liabilities based on the application of a financial-components approach that focuses on control. After a transfer of financial assets, the Company recognizes the financial and servicing assets it controls and liabilities it has incurred, derecognizes financial assets when control has been surrendered and derecognizes liabilities when extinguished. The Company has retained mortgage servicing rights in connection with the sale of mortgage loans. Because the Company may not initially identify loans as originated for resale, all loans are initially treated as held for investment. The value of the mortgage servicing rights are reviewed periodically for impairment and are amortized in proportion to, and over the period of estimated net servicing income or net servicing losses. The value of the mortgage servicing rights is not significant to the consolidated statements of condition. | |

New Accounting Standards | ' |
New Accounting Standards | |
        In February 2013, the Financial Accounting Standards Board issued Accounting Standards Update No. 2013-02 to ASC 220, "Comprehensive Income." The update amends existing literature to require an entity to provide information about the amounts reclassified out of other comprehensive income by component, and it also requires enhanced disclosure and cross reference on items reclassified out of accumulated other comprehensive income during the reporting period. The update is effective for reporting periods beginning after December 15, 2012. The adoption of the update to existing standards did not have a significant impact to the Company's consolidated financial statements. | |
        In July 2013, the Financial Accounting Standards Board issued Accounting Standards Update No. 2013-11 to ASC 740, "Income Taxes." The update amends existing literature to eliminate diversity in practice in the presentation of unrecognized tax benefits in instances where a net operating loss carryforward, a similar tax loss or a tax credit carryforward also exist. The update clarifies how the unrecognized tax benefit should be presented in those situations where other tax losses or tax credit carryforwards exist. The update does not change the currently required disclosures for unrecognized tax benefits under current ASC 740 guidance. The update is effective for fiscal years and interim periods within those years beginning after December 15, 2013. The adoption of the update to existing standards is not expected to have a significant impact to the Company's consolidated financial statements. | |
        In January 2014, the Financial Accounting Standards Board issued Accounting Standards Update No. 2014-04 to ASC 310-40, "Receivables—Troubled Debt Restructurings by Creditors." The update amends existing literature to eliminate diversity in practice by clarifying and defining when an in substance repossession or foreclosure occurs. The terms "in substance a repossession or foreclosure" and "physical possession" are not currently defined in the accounting literature, resulting in diversity in practice when a creditor derecognizes a loan receivable and recognizes the real estate property collateralizing the loan receivable as an asset. Additionally, the update requires interim and annual disclosures of both the amount of foreclosed residential real estate property and the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure. The update is effective for annual periods and the interim periods within those annual periods beginning after December 15, 2014. The adoption of the update to existing standards is not expected to have a significant impact to the Company's consolidated financial statements. | |
