Basis of Presentation | Note 1 — Basis of Presentation ​ Our accounting and reporting policies conform to accounting principles generally accepted in the United States of America and to general practices within the banking industry. Our consolidated financial statements include the accounts of International Bancshares Corporation, and our wholly-owned bank subsidiaries, International Bank of Commerce, Laredo (“IBC”), Commerce Bank, International Bank of Commerce, Zapata, International Bank of Commerce, Brownsville, International Bank of Commerce, Oklahoma (the “Subsidiary Banks”) and our wholly-owned non-bank subsidiaries, IBC Trading Company, Premier Tierra Holdings, Inc., IBC Charitable and Community Development Corporation, and IBC Capital Corporation. Effective January 1, 2019, we dissolved one of our non-bank subsidiaries, IBC Subsidiary Corporation, a second-tier bank holding company incorporated in the State of Delaware. All significant inter-company balances and transactions have been eliminated in consolidation. Our consolidated financial statements are unaudited, but include all adjustments, which, in the opinion of management, are necessary for a fair presentation of the results of the periods presented. All such adjustments were of a normal and recurring nature. These financial statements should be read in conjunction with the financial statements and the notes thereto in our latest Annual Report on Form 10-K. Our consolidated statement of condition at December 31, 2018 has been derived from the audited financial statements at that date but does not include all of the information and footnotes required by accounting principles generally accepted in the United States of America (“US GAAP”) for complete financial statements. Certain reclassifications have been made to make prior periods comparable. Operating results for the three and nine months ended September 30, 2019 are not necessarily indicative of the results for the year ending December 31, 2019 or any future period. ​ We operate as one segment. The operating information used by our chief executive officer for purposes of assessing performance and making operating decisions is the consolidated statements presented in this report. We have five active operating subsidiaries, the Subsidiary Banks. We apply the provisions of Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”), FASB ASC 280, “Segment Reporting,” in determining our reportable segments and related disclosures. ​ We have evaluated all events or transactions that occurred through the date we issued these financial statements. During this period, we did not have any material recognizable or non-recognizable subsequent events. ​ On January 1, 2019, we adopted the provisions of ASU 2016-02, “Leases.” ASU 2016-02 amends existing standards for accounting for leases by lessees, with accounting for leases by lessors remaining mainly unchanged from current guidance. The update requires that lessees recognize a lease liability and a right of use asset for all leases (with the exception of short-term leases) at the commencement date of the lease and disclose key information about leasing arrangements. The update is to be applied on a modified retrospective basis for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the consolidated financial statements. In January 2018, the FASB issued a proposal that provides an additional transition method that would allow entities to not apply the guidance in the update in the comparative periods presented in the consolidated financial statements, but instead recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. As part of our business model, we primarily own all property we occupy, with the exception of certain branches operating in grocery stores or shopping centers and certain ATM locations that were classified as operating leases under previous guidance. The adoption of the standard did not have a significant impact on our consolidated financial statements. As of the date of adoption, we recorded a right of use asset and a lease liability of approximately $6.4 million. The right of use asset and lease liability are included in other assets and other liabilities, respectively, on our consolidated statement of condition. Amortization of the right of use asset for the three and nine months ended September 30, 2019 was approximately $267,000 and $726,000, respectively, and is included as a part of occupancy expense in our consolidated income statement. ​ In June 2016, the FASB issued Accounting Standards Update No. 2016-13 to ASC 326, “Financial Instruments – Credit Losses.” The update amends existing standards for accounting for credit losses for financial assets. The update requires that the expected credit losses on the financial instruments held as of the end of the period being reported be measured based on historical experience, current conditions, and reasonable and supportable forecasts. The update also expands the required disclosures related to significant estimates and judgements used in estimating credit losses, as well as the credit quality and underwriting standards of an organization’s financial assets. The update also amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. The impact of the adoption of the standard is to be recorded as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted. The accounting standard will be effective for us on January 1, 2020. We continue to evaluate the impact the adoption of the update will have on us and do not have a current estimate, however, we do expect that that final impact of the adoption could be significantly impacted by a change in the mix of loans, characteristics and quality of our loan portfolio at the end of the year as well the economic conditions and forecasts at the time of adoption. The task force formed last year, which includes key members of the teams that work with the current calculation of the allowance for probable loan losses with members representing the corporate accounting and risk management areas has continued to work with the implementation of the update. Initial implementation activities and decisions have been reached around key data needed for the new calculation including portfolio segmentation. Validation of our primary model/tool is substantially completed and ongoing activities around forecasting models and documentation of the process will continue during the fourth quarter of 2019.
