Texas Capital Bancshares, Inc. (the "Company”), a Delaware corporation, was incorporated in November 1996 and commenced banking operations in December 1998. The consolidated financial statements of the Company include the accounts of Texas Capital Bancshares, Inc. and its wholly owned subsidiary, Texas Capital Bank, National Association (the "Bank”). We serve the needs of commercial businesses and successful professionals and entrepreneurs located in Texas as well as operate several lines of business serving a regional or national clientele of commercial borrowers. We are primarily a secured lender, with the majority of our loans held for investment, excluding mortgage finance loans and other national lines of business, being made to businesses headquartered or with operations in Texas. Our national lines of business provide specialized leading products to businesses throughout the United States.

On December 9, 2019, the Company entered into a merger agreement with IBTX, the holding company for Independent Bank, under which TCBI and IBTX will combine in an all-stock merger of equals. Under the terms of the merger agreement, each share of TCBI common stock outstanding immediately prior to the effective time, other than certain shares held by TCBI or IBTX, will be converted into the right to receive the merger consideration of 1.0311 shares of IBTX common stock. At the effective time, each outstanding share of TCBI preferred stock will be automatically converted into the right to receive one share of IBTX preferred stock having substantially the same terms as such share of TCBI preferred stock. The name of the surviving entity will be Independent Bank Group, Inc. and the name of the surviving bank will be Texas Capital Bank. The surviving bank will be operated under the name Independent Financial in Colorado and under the name Texas Capital Bank in Texas.

The merger agreement was unanimously approved by the board of directors of TCBI and the board of directors of IBTX. The merger is expected to close in mid-2020, subject to satisfaction of customary closing conditions, including receipt of customary regulatory approvals and approval of the merger agreement by the stockholders of TCBI and the shareholders of IBTX, respectively. For more information on the merger agreement and the merger, see Part I, Item 1, Business-Merger with Independent Bank Group, Inc.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. The allowance for loan losses, the fair value of financial instruments and the status of contingencies are particularly susceptible to significant change.

Basic earnings per common share is based on net income available to common stockholders divided by the weighted-average number of common shares outstanding during the period excluding non-vested stock. Diluted earnings per common share include the dilutive effect of non-vested stock-based awards granted using the treasury stock method. A reconciliation of the weighted-average shares used in calculating basic earnings per common share and the weighted average common shares used in calculating diluted earnings per common share for the reported periods is provided in Note 2 — Earnings Per Share.

Unrealized gains or losses on our available-for-sale debt securities (after applicable income tax expense or benefit) are included in accumulated other comprehensive income (loss), net ("AOCI"). AOCI is reported in the accompanying consolidated statements of stockholders’ equity and consolidated statements of income and other comprehensive income.

GAAP does not permit the adjustment of tax amounts in AOCI for changes in tax rates; as a result the effects become "stranded" in AOCI. Stranded tax effects caused by the 2018 revaluation of deferred taxes resulting from the corporate tax rates established by the Tax Cuts and Jobs Act (the "Tax Act") are reclassified from AOCI to retained earnings in accordance with our early adoption of ASU 2018-02 "Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income."

Available-for-sale debt securities are stated at fair value, with the unrealized gains and losses reported as a separate component of AOCI, net of tax. The amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity, or in the case of mortgage-backed securities, over the estimated life of the security. Such amortization and accretion are included in interest income from securities. Realized gains and losses and declines in value judged to be other-than-temporary are included in gain (loss) on sale of securities. The cost of securities sold is based on the specific identification method.

Beginning January 1, 2018, upon adoption of ASU 2016-01 "Recognition and Measurement of Financial Assets and Financial Liabilities," equity securities with readily determinable fair values are stated at fair value with realized and unrealized gains and losses reported in income. For periods prior to January 1, 2018, equity securities were classified as available-for-sale and stated at fair value with unrealized gains and losses reported as a separate component of AOCI, net of tax. Equity securities without readily determinable fair values are recorded at cost less any impairment, if any.

Through our mortgage correspondent aggregation ("MCA") program, we commit to purchase residential mortgage loans from independent correspondent lenders and deliver those loans into the secondary market via whole loan sales to independent third parties or in securitization transactions to third parties such as Ginnie Mae or to government sponsored entities such as Fannie Mae or Freddie Mac ("GSEs"). In some cases, we retain the mortgage servicing rights. Once purchased, these loans are classified as held for sale and are carried at fair value pursuant to our election of the fair value option in accordance with Accounting Standards Codification ("ASC") 825, Financial Instruments. At the commitment date, we enter into a corresponding forward sale commitment with a third party, typically Ginnie Mae or a GSE, to deliver the loans within a specified timeframe. The estimated gain/loss for the entire transaction (from initial purchase commitment to final delivery of loans) is recorded as an asset or liability. The fair value of loans held for sale is derived from observable current market prices, when available, and includes the fair value of the mortgage servicing rights. Adjustments to reflect unrealized gains and losses resulting from changes in fair value and realized gains and losses upon ultimate sale of the loans are classified as gain/(loss) on sale of loans held for sale in the consolidated statements of income and other comprehensive income.

Residential mortgage loans held for sale are subject to both credit and interest rate risk. Credit risk is managed through underwriting policies and procedures, including collateral requirements, which are generally accepted by the secondary loan markets. Exposure to interest rate fluctuations is partially managed through forward sales contracts, which set the price for loans that will be delivered in the next 60 to 90 days.

have been met, and regardless of whether the repurchase option has been exercised, we account for these loans as if they had been repurchased and recognize the loans and a corresponding liability as held for sale and other liabilities, respectively, in the consolidated balance sheets. If the loans are actually repurchased, the liability is extinguished and the loans continue to be reported as held for sale. As a Ginnie Mae approved lender, we may recover losses incurred on repurchased loans through a claims process with the government agency.

Loans held for investment (including financing leases) are stated at the amount of unpaid principal reduced by deferred income (net of costs). Interest on loans is recognized using the simple-interest method on the daily balances of the principal amounts outstanding. Loan origination fees, net of direct loan origination costs, and commitment fees, are deferred and amortized as an adjustment to yield over the life of the loan, or over the commitment period, as applicable.

A loan held for investment is considered impaired when, based on current information and events, it is probable that we will be unable to collect all amounts due (both principal and interest) according to the terms of the loan agreement. Reserves on impaired loans are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate or the fair value of the underlying collateral, less cost to sell. Impaired loans, or portions thereof, are charged off when a confirmed loss exists.

Restructured loans are loans on which, due to the borrower’s financial difficulties, we have granted a concession that we would not otherwise consider for borrowers of similar credit quality. This may include a transfer of real estate or other assets from the borrower, a modification of loan terms, or a combination of the two. Modifications of terms that could potentially qualify as a restructuring include reduction of contractual interest rate, extension of the maturity date at a contractual interest rate lower than the current rate for new debt with similar risk, a reduction of the face amount of debt or forgiveness of either principal or accrued interest. A loan continues to qualify as restructured until a consistent payment history or change in borrower’s financial condition has been evidenced, generally for no less than twelve months. Assuming that the restructuring agreement specifies an interest rate at the time of the restructuring that is greater than or equal to the rate that we are willing to accept for a new extension of credit with comparable risk, then the loan no longer has to be considered a restructuring if it is in compliance with the modified terms in calendar years after the year of the restructure.

The accrual of interest on loans is discontinued when there is a clear indication that the borrower’s cash flow may not be sufficient to meet payments as they become due, which is generally when a loan is 90 days past due. When a loan is placed on non-accrual status, all previously accrued and unpaid interest is reversed. Interest income is subsequently recognized on a cash basis as long as the remaining book balance of the asset is deemed to be collectible. If collectability is questionable, then cash payments are applied to principal. A loan is placed back on accrual status when both principal and interest are current and it is probable that we will be able to collect all amounts due (both principal and interest) according to the terms of the loan agreement.

Loans held for investment includes legal ownership interests in mortgage loans that we purchase through our mortgage warehouse lending division. The ownership interests are purchased from unaffiliated mortgage originators who are seeking additional funding through sale of the undivided ownership interests to facilitate their ability to originate loans. The mortgage originator has no obligation to offer and we have no obligation to purchase these interests. The originator closes mortgage loans consistent with underwriting standards established by approved investors, and, at the time of the sale to the investor, our ownership interest and that of the originator are delivered by us to the investor selected by the originator and approved by us. We typically purchase up to a 99% ownership interest in each mortgage with the originator owning the remaining percentage. These mortgage ownership interests are generally held by us for a period of less than 30 days and more typically 10-20 days. Because of conditions in agreements with originators designed to reduce transaction risks, under ASC 860, Transfers and Servicing of Financial Assets (“ASC 860”), the ownership interests do not qualify as participating interests. Under ASC 860, the ownership interests are deemed to be loans to the originators and payments we receive from investors are deemed to be payments made by or on behalf of the originator to repay the loan deemed made to the originator. Because we have an actual, legal ownership interest in the underlying residential mortgage loan, these interests are reported as extensions of credit to the originators that are secured by the mortgage loans as collateral.

Due to market conditions or events of default by the investor or the originator, we could be required to purchase the remaining interests in the mortgage loans and hold them beyond the expected 10-20 days. Mortgage loans acquired under these conditions would require mark-to-market adjustments to income and could require further allocations of the allowance for loan losses or be subject to charge off in the event the loans become impaired.

The allowance for loan losses is comprised of general reserves and specific reserves for impaired loans, all based on our estimate of losses inherent in the portfolio at the balance sheet date. In order to determine the allowance for loan losses, all loans are assigned a credit grade. Loan commitments graded substandard or worse and greater than $500,000 are specifically reviewed for loss potential. Loans deemed to be impaired, as well as restructured loans and loans formerly reported as restructured, are assigned a specific reserve based on the losses expected to be realized from those loans. For purposes of determining the general reserve, the remainder of the portfolio is segregated by product types to recognize differing risk profiles among portfolio segments, and then further segregated by credit grades. Each credit grade is assigned a risk factor, or reserve allocation percentage. These risk factors are multiplied by the outstanding principal balance of each loan and risk-weighted by product type to calculate a required reserve. A similar process is employed to calculate a reserve assigned to off-balance sheet commitments, specifically unfunded loan commitments and letters of credit, and any needed reserve is recorded in other liabilities. Even though portions of the allowance may be allocated to specific loans, the entire allowance is available for any credit that, in management’s judgment, should be charged off.

We have several pass credit grades that are assigned to loans based on varying levels of risk, ranging from credits that are secured by cash or marketable securities, to watch credits which have all the characteristics of an acceptable credit risk but warrant more than the normal level of monitoring. Within our criticized/classified credit grades are special mention, substandard, and doubtful. Special mention loans are those that are currently protected by the sound worth and paying capacity of the borrower, but that are potentially weak and constitute an additional credit risk. These loans have the potential to deteriorate to a substandard grade due to the existence of financial or administrative deficiencies. Substandard loans have a well-defined weakness or weaknesses that jeopardizes the liquidation of the debt. They are characterized by the distinct possibility that we will sustain some loss if the deficiencies are not corrected. Some substandard loans are inappropriately protected by the sound worth and paying capacity of the borrower and of the collateral pledged and may be considered impaired. Substandard loans can be accruing or can be on non-accrual depending on the circumstances of the individual loans. Loans classified as doubtful have all the weaknesses inherent in substandard loans with the added characteristics that the weaknesses make collection or liquidation in full highly questionable and improbable. The possibility of loss is extremely high. All doubtful loans are on non-accrual.

The allowance allocation percentages assigned to each credit grade have been developed based primarily on an analysis of our historical loss rates. The level of the allowance reflects management’s continuing evaluation of conditions likely to impact the amount of losses expected to be incurred in the Bank’s loan portfolio. Such conditions include, without limitation, credit quality indicators such as amounts and percentages of loans classified as past due, criticized and non-performing, conditions internal to the Bank such as the skill and experience of lending and credit personnel and effectiveness of credit review processes, the rate of portfolio growth, the extent of hold limits and loan concentrations, such as loans to specific borrowers, loans to groups of affiliated borrowers, loans to borrowers in defined industry groups and loans to borrowers, and collateral, in defined geographic locations. Conditions external to the Bank that may impact incurred losses that are also considered by management in the evaluation of the allowance include the general health of the national economy and regional economies where the Bank operates, international economic conditions, domestic and international political events that may impact the Bank’s loan portfolio, regulatory developments deemed relevant to risk assessment and classification of credits and circumstances that may have negative consequences for industries or specific borrowers where the Bank has exposure.

Management’s assessment of the allowance begins with a review of historical credit loss experience as a baseline before consideration of current environmental issues both internal and external to the Bank that might reasonably cause the measure of incurred loss to differ from historical experience. The Bank’s allowance methodology employs a loss migration technique to determine historical loss percentages applicable to all defined credit risk grades. The methodology also calculates historical loss percentages by portfolio segment and computes segment weights as a measure of the relative risk of loans in each segment compared to the entire portfolio. Management may adjust segment weights by applying overlays to specific portfolio segments whereby historical loss experience may not be a measure reflective of incurred losses for the specific portfolio segment. These overlays are quantified by management at the portfolio segment level and added or subtracted from historical loss rates. These processes allow for a continuous review of not only absolute historical loss percentages but also an assessment of credit risk grade migration, positive and negative, and changes in portfolio composition as defined by portfolio segment.

Because credit risk grade migration, both positive and negative, can significantly trail triggering events such as change in economic conditions, commodity prices or interest rates, changes in collateral values or changes in regulatory interpretation or applicable laws or standards impacting the Bank's lending activities, management has identified certain measures that are believed to offer guidance as leading, concurrent and trailing indicators respectively of general economic health that in turn are thought to be relevant to the measure of incurred loss in the Bank’s loan portfolio (individually referred to as "Q Factors"). Each individual Q Factor is individually quantified by management and then aggregated into a single qualitative adjustment (referred to as the "Q Factor adjustment"). This Q Factor adjustment is added or subtracted from historical loss rates, as relevant, to compute an appropriate reserve based upon actual portfolio composition as defined by portfolio segment and credit risk grade composition.

The single Q Factor adjustment and application of any management overlay to model calculated segment weights reflects management’s determination that the allowance model is calculating an appropriate level of the allowance in the context of all known loan portfolio quality and concentration issues as well as other environmental factors that are reasonably believed to cause the measure of incurred loss, inclusive of unidentified losses inherent in the current portfolio, to differ from historical experience.

The methodology used in the periodic review of the appropriateness of the allowance, which is performed at least quarterly, is designed to be dynamic and responsive to changes in portfolio credit quality. Changes are reflected in the general allowance and in specific reserves as the collectability of classified loans is evaluated with new information. As our portfolio has matured, historical loss ratios have been closely monitored. Our reserve appropriateness relies primarily on our loss history. The review of the appropriateness of the allowance is performed by executive management and presented to the audit and risk committees of our board of directors for their review. The committees report to the board as part of the board's review on a quarterly basis of the Company's consolidated financial statements.

Other real estate owned (“OREO”), which is included in other assets on the consolidated balance sheet, consists of real estate that has been foreclosed. When foreclosure occurs, the acquired asset is recorded at fair value less selling costs, generally based on appraised value, which may result in partial charge-off of the loan through a charge to the allowance for loan losses, if necessary. Subsequent write-downs required for declines in value are recorded through a valuation allowance, or taken directly to the asset, and are recorded in allowance and other carrying costs for OREO in the consolidated statements of income and other comprehensive income. Gains or losses on sale of OREO are recorded in other non-interest income in the consolidated statements of income and other comprehensive income.

Mortgage servicing rights ("MSRs") are created by selling mortgage loans with servicing rights retained. We identify classes of servicing rights based upon the nature of the underlying assumptions used to value the asset along with the risks associated with the underlying asset. Based upon these criteria we have one class of MSRs, residential.

MSRs are recognized based on the estimated fair value of the mortgage loans and the related servicing rights at the date of sale using values derived from a valuation model. MSRs are reported on the consolidated balance sheets at amortized cost, less a valuation allowance if the fair value of identified strata within the MSR portfolio are determined to have a fair value that is less than amortized cost. MSRs are amortized proportionally over the estimated life of the projected net servicing revenue and are periodically evaluated for impairment. Loan servicing fee income represents income earned for servicing mortgage loans owned by investors and includes mortgage servicing fees and other ancillary servicing income. Servicing fees are recorded as income when earned and are reported in non-interest income on the consolidated statements of income and other comprehensive income. MSR valuation allowance expense and servicing related expenses are recorded in servicing related expenses in the consolidated statements of income and other comprehensive income.

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. Our intangible assets relate primarily to loan customer relationships purchased as part of business acquisitions. Intangible assets with definite useful lives are amortized over their estimated life. Goodwill and intangible assets are tested for impairment at least annually or whenever changes in circumstances indicate the carrying amount of the assets may not be recoverable from future undiscounted cash flows. If impaired, the assets are recorded at fair value.

Premises and equipment are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets. Furniture and equipment is generally depreciated over three to five years, while leasehold improvements are generally depreciated over the term of their respective lease. Gains or losses on disposals of premises and equipment are included in other non-interest income in the consolidated statements of income and other comprehensive income.

Costs incurred in connection with development or purchase of internal use software and cloud computing arrangements, including in-substance software licenses, are capitalized. Amortization is computed on a straight-line basis over the estimated useful life of the asset, which generally ranges from one to five years. Capitalized software is included in other assets in the consolidated balance sheets.

The Company has undertaken certain guarantee obligations in the ordinary course of business which include liabilities with off-balance sheet risk. We consider the following arrangements to be guarantees: commitments to extend credit, standby letters of credit and indemnification agreements included within third party contractual arrangements.

The Bank is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit that involve varying degrees of credit risk in excess of the amount recognized in the consolidated balance sheets. The Bank’s exposure to credit loss in the event of non-performance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual amount of these instruments. The Bank uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. The amount of collateral obtained, if deemed necessary, is based on management’s credit evaluation of the borrower.

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 or other termination clauses and may require payment of a fee. Since many of the commitments may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Bank evaluates each customer’s creditworthiness on a case-by-case basis.

Standby letters of credit are conditional commitments issued by the Bank to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support public and private borrowing arrangements. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers.

In conjunction with the sale and securitization of loans held for sale and their related servicing rights, we may be exposed to liability resulting from recourse and repurchase agreements. If it is determined subsequent to our sale of a loan or its related servicing rights that a breach of the representations or warranties made in the applicable sale agreement has occurred, which may include guarantees that prepayments will not occur within a specified and customary time frame, we may have an obligation to either (a) repurchase the loan for the unpaid principal balance, accrued interest and related advances, (b) indemnify the purchaser against any loss it suffers or (c) make the purchaser whole for the economic benefits of the loan and its related servicing rights.

Our repurchase, indemnification and make-whole obligations vary based upon the terms of the applicable agreements, the nature of the asserted breach and the status of the mortgage loan at the time a claim is made. We establish reserves for estimated losses of this nature inherent in the origination of mortgage loans by estimating the losses inherent in the population of all loans sold based on trends in claims and actual loss severities experienced. The reserve will include accruals for probable contingent losses in addition to those identified in the pipeline of claims received. The estimation process is designed to include amounts based on actual losses experienced from actual activity.

ASU 2016-02 "Leases (Topic 842)" ("ASU 2016-02") requires that lessees and lessors recognize lease assets and lease liabilities on the balance sheet and disclose key information about leasing arrangements. ASU 2016-02 became effective for us on January 1, 2019. ASU 2016-02 provides for a modified retrospective transition approach requiring lessees to recognize and measure leases on the balance sheet at the beginning of either the earliest period presented or as of the beginning of the period of adoption with the option to elect certain practical expedients. We elected to apply ASU 2016-02 as of the beginning of the period of adoption (January 1, 2019) and have not restated comparative periods. Of the optional practical expedients available under ASU 2016-02, we adopted all expedients except for the hindsight practical expedient. As a result of implementing ASU 2016-02, we recognized an operating lease right-of-use ("ROU") asset of $64 million and an operating lease liability of $74 million on January 1, 2019, with no impact on our consolidated statements of income or consolidated statements of cash flows compared to the prior lease accounting model.

Operating lease ROU assets represent our right to use an underlying asset during the lease term and operating lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and operating lease liabilities are recognized at lease commencement based on the present value of the remaining lease payments using a discount rate that represents our incremental borrowing rate at the lease commencement date, which is based on our collateralized borrowing capabilities over a similar term as the related lease payments. ROU assets are further adjusted for lease incentives.

Our operating leases relate primarily to office space and bank branches. Operating leases in which we are the lessee are recorded as operating lease ROU assets and operating lease liabilities, included in other assets and other liabilities, respectively, on our consolidated balance sheets. Operating lease expense, which is comprised of amortization of the ROU asset and the implicit interest accreted on the operating lease liability, is recognized on a straight-line basis over the lease term, and is recorded in net occupancy expense in the consolidated statements of income and other comprehensive income. See Note 7 – Leases for additional information.

ASC 606, Revenue from Contracts with Customers ("ASC 606"), establishes principles for reporting information about the nature, amount, timing and uncertainty of revenue and cash flows arising from the entity's contracts to provide goods or services to customers. The core principle requires an entity to recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration that it expects to be entitled to receive in exchange for those goods or services recognized as performance obligations are satisfied.

The majority of our revenue-generating transactions are not subject to ASC 606, including revenue generated from financial instruments, such as our loans, letters of credit, derivatives and investment securities, as well as revenue related to our mortgage servicing activities, as these activities are subject to other GAAP discussed elsewhere within our disclosures. Descriptions of our revenue-generating activities that are within the scope of ASC 606, which are presented in our income statements as components of non-interest income are as follows:

We account for all stock-based compensation transactions in accordance with ASC 718, Compensation — Stock Compensation (“ASC 718”), which requires that stock compensation transactions be recognized as compensation expense in the consolidated statements of income and other comprehensive income based on their fair values on the measurement date, which is the date of the grant.

The Company and its subsidiary file a consolidated federal income tax return. We utilize the liability method in accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based upon the difference between the values of the assets and liabilities as reflected in the financial statements and their related tax basis using enacted tax rates in effect for the year in which the differences are expected to be recovered or settled. As changes in tax law or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes. A valuation allowance is provided against deferred tax assets unless it is more likely than not that such deferred tax assets will be realized.

ASC 820, Fair Value Measurements and Disclosures (“ASC 820”), defines fair value, establishes a framework for measuring fair value under GAAP and enhances disclosures about fair value measurements. In general, fair values of financial instruments are based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows.

We enter into interest rate derivative contracts that are not designated as hedging instruments. These derivative positions relate to transactions in which we enter into an interest rate swap, cap and/or floor with a customer while at the same time entering into an offsetting interest rate swap, cap and/or floor with another financial institution. In connection with each swap transaction, we agree to pay interest to the customer on a notional amount at a variable interest rate and receive interest from the customer on a similar notional amount at a fixed interest rate. At the same time, we agree to pay another financial institution the same fixed interest rate on the same notional amount and receive the same variable interest rate on the same notional amount. The transaction allows our customer to effectively convert a variable rate loan to a fixed rate. Because we act as an intermediary for our customer, changes in the fair value of the underlying derivative contracts substantially offset each other and do not have a material impact on our results of operations.

We also enter into foreign currency forward contracts that are not designed as hedging instruments. These derivative instruments relate to transactions in which we enter into a contract with a customer to buy or sell a foreign currency at a future date for a specified price while at the same time entering into an offsetting contract with a financial institution to buy or sell the same currency at the same future date for a specified price. These transactions allow our customers to manage their exposure to foreign currency exchange rate fluctuations. Because we act as an intermediary for our customer, changes in the fair value of the underlying derivative instruments substantially offset each other and do not have a material impact on our results of operations.

We also enter into loan purchase commitment contracts with mortgage originators to purchase residential mortgage loans at a future date, as well as forward sales commitment contracts to sell residential mortgage loans at a future date, as part of our MCA program. The objective of these transactions is to mitigate our exposure to interest rate risk associated with the purchase of mortgage loans held for sale. Any changes in fair value are recorded in other non-interest expense in the consolidated statements of income and other comprehensive income.
