Accounting Policies [Abstract]
Summary of Significant Accounting Policies	NOTE 1 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations Triumph Bancorp, Inc. (collectively with its subsidiaries, “Triumph”, or the “Company” as applicable) is a financial holding company headquartered in Dallas, Texas. The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries Triumph CRA Holdings, LLC (“TCRA”), TBK Bank, SSB (“TBK Bank”), TBK Bank’s wholly owned factoring subsidiary Advance Business Capital LLC, which currently operates under the d/b/a of Triumph Business Capital (“TBC”), and TBK Bank’s wholly owned subsidiary Triumph Insurance Group, Inc. (“TIG”). On March 31, 2017 the Company sold its membership interest in its wholly owned subsidiary Triumph Capital Advisors, LLC (“TCA”). See Note 2 – Business Combinations and Divestitures for details of the TCA sale and its impact on the Company’s consolidated financial statements. On January 19, 2018, the Company entered into an agreement to sell the assets (the “Disposal Group”) of Triumph Healthcare Finance (“THF”), and exit its healthcare asset-based lending line of business. THF operates within the TBK Bank, SSB subsidiary. The decision to sell THF was made prior to the end of the year, and at December 31, 2017, the fair value of the Disposal Group exceeded its carrying amount. As a result of this decision, the carrying amount of the Disposal Group was transferred to assets held for sale. See Note 2 – Business Combinations and Divestitures for additional information pertaining to the Disposal Group and the impact of the transaction on the Company’s consolidated financial statements. Principles of Consolidation and Basis of Presentation The Company consolidates subsidiaries in which it holds, directly or indirectly, a controlling financial interest. The Company determines whether it has a controlling financial interest in an entity by first evaluating whether the entity is a voting interest entity or a variable interest entity under U.S. generally accepted accounting principles (“GAAP”). Voting interest entities are entities in which the total equity investment at risk is sufficient to enable the entity to finance itself independently and provides the equity holders with the obligation to absorb losses, the right to receive residual returns and the right to make decisions about the entity’s activities. The Company consolidates voting interest entities in which it has at least a majority of the voting interest. Variable interest entities (“VIEs”) are entities that lack one or more of the characteristics of a voting interest entity. A controlling financial interest in a VIE is present when an enterprise has both the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and an obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. The enterprise with a controlling financial interest, known as the primary beneficiary, consolidates the VIE. In consolidation, all significant intercompany accounts and transactions are eliminated. Investments in unconsolidated entities are accounted for using the equity method of accounting when the Company has the ability to exercise significant influence over operating and financing decisions. Investments that do not meet the criteria for equity method accounting are accounted for using the cost method of accounting. The accounting and reporting policies of the Company and its subsidiaries conform to GAAP and general practice within the banking industry. Certain reclassifications have been made to prior year amounts to conform to the current year presentation. The Company uses the accrual basis of accounting for financial reporting purposes. Use of Estimates To prepare financial statements in conformity with GAAP management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided, and actual results could differ. Cash and Cash Equivalents For the purposes of reporting cash flows, cash and cash equivalents include cash on hand, amounts due from banks, other short term investments and federal funds sold. All highly liquid investments with an initial maturity of less than 90 days are considered to be cash equivalents. Certain items, including loan and deposit transactions, customer repurchase agreements, and FHLB advances and repayments, are presented net in the statement of cash flows. Securities The Company determines the classification of securities at the time of purchase. Debt securities that management has the positive intent and ability to hold to maturity are classified as held to maturity and recorded at amortized cost. Trading securities are recorded at fair value with changes in fair value included in earnings. Securities not classified as held to maturity or trading are classified as available for sale and recorded at fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive income (loss), net of tax. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific-identification method. Amortization of premiums and discounts are recognized in interest income over the period to maturity using the interest method. Management evaluates securities for other-than-temporary impairment (“OTTI”) on a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. For securities in an unrealized loss position, management considers the extent and duration of the unrealized loss, and the financial condition and near-term prospects of the issuer. Management also assesses whether it intends to sell, or it is more likely than not that it will be required to sell, a security in an unrealized loss position before recovery of its amortized cost basis. In analyzing an issuer’s financial condition, the Company may consider whether the securities are issued by the federal government or its agencies, whether downgrades by bond rating agencies have occurred, and the results of reviews of the issuers’ financial condition. The Company conducts regular reviews of the bond agency ratings of securities and considers whether the securities were issued by or have principal and interest payments guaranteed by the federal government or its agencies. These reviews focus on the underlying rating of the issuer and also include the insurance rating of securities that have an insurance component or guarantee. The ratings and financial condition of the issuers are monitored, as well as the financial condition and ratings of the insurers and guarantors. If either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost and fair value is recognized as impairment through earnings. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: 1) OTTI related to credit loss, which must be recognized through earnings, and 2) OTTI related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. For equity securities, the entire amount of impairment is recognized through earnings. Loans Held for Sale The Company elects the fair value option for recording mortgage loans originated and intended for sale in the secondary market in accordance with Accounting Standards Codification (“ASC”) 825, “Financial Instruments”. The fair value of mortgage loans held for sale is determined based on outstanding commitments from investors to purchase such loans and upon prevailing market rates. Increases or decreases in the fair value of these loans held for sale, if any, are charged to earnings through net gains on sale of loans. Mortgage loans held for sale are generally sold with servicing rights released. Gains and losses on sales of mortgage loans are based on the difference between the final selling price and the fair value of the related loan sold. The Company originated and sold mortgage loans during the years ended December 31, 2016 and 2015 and these activities are reflected in the Consolidated Statements of Income and the Consolidated Statements of Cash Flows for these respective years; however, there were no mortgage loans held for sale carried on the Consolidated Balance Sheets at December 31, 2017 and 2016 as the Company made the decision to exit the residential mortgage production business in the fourth quarter of 2015. Management occasionally transfers non-mortgage loans from held for investment to held for sale. Gains or losses on the sale of these loans are recorded in noninterest income. Loans Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at the unpaid principal balance outstanding, net of unearned income, deferred loan fees and costs, and any direct principal charge-offs. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized in interest income over the remaining life of the loan without anticipating prepayments. Loans are considered past due or delinquent when the contractual principal or interest due in accordance with the terms of the loan agreement or any portion thereof remains unpaid after the due date of the scheduled payment. Loans are classified as nonaccrual when, in the opinion of management, collection of principal or interest is doubtful. The accrual of interest income on loans is typically discontinued at the time the loan is 90 days delinquent unless the loan is well-secured and in process of collection, or if full collection of interest or principal becomes uncertain. Consumer loans are typically charged off no later than 120 days past due. Past due status is based on the contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged-off at an earlier date if collection of principal or interest is considered doubtful. All interest accrued but not received for a loan placed on nonaccrual is reversed against interest income. Interest received on such loans is accounted for on the cash-basis or cost recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. Acquired Loans Acquired loans are recorded at fair value at the date of acquisition with no initial valuation allowance based on a discounted cash flow methodology that considers various factors including the type of loan and related collateral, classification status, fixed or variable interest rate, term of loan and whether or not the loan was amortizing, and a discount rate reflecting the Company’s assessment of risk inherent in the cash flow estimates. Certain larger purchased loans are individually evaluated while certain purchased loans are grouped together according to similar risk characteristics and are treated in the aggregate when applying various valuation techniques. These cash flow evaluations are inherently subjective as they require material estimates, all of which may be susceptible to significant change. Loans acquired in a business combination that have evidence of deterioration of credit quality since origination and for which it is probable, at acquisition, that the Company will be unable to collect all contractually required payments receivable are considered purchased credit impaired (“PCI”). PCI loans are individually evaluated and recorded at fair value at the date of acquisition with no initial valuation allowance based on a discounted cash flow methodology that considers various factors including the type of loan and related collateral, classification status, fixed or variable interest rate, term of loan and whether or not the loan was amortizing, and a discount rate reflecting the Company’s assessment of risk inherent in the cash flow estimates. The difference between the undiscounted cash flows expected at acquisition and the investment in the loan, or the “accretable yield,” is recognized as interest income on a level-yield method over the life of the loan. Contractually required payments for interest and principal that exceed the undiscounted cash flows expected at acquisition, or the “nonaccretable difference,” are not recognized on the balance sheet and do not result in any yield adjustments, loss accruals or valuation allowances. Increases in expected cash flows, including prepayments, subsequent to the initial investment are recognized prospectively through adjustment of the yield on the loan over its remaining life. Decreases in expected cash flows are recognized as impairment. Valuation allowances on PCI loans reflect only losses incurred after the acquisition (meaning the present value of all cash flows expected at acquisition that ultimately are not to be received). For acquired loans not deemed credit-impaired at acquisition, the differences between the initial fair value and the unpaid principal balance are recognized as interest income on a level-yield basis over the lives of the related loans. Subsequent to the acquisition date, methods utilized to estimate the required allowance for loan and lease losses for these loans is similar to originated loans; however, a provision for credit losses will be recorded only to the extent the required allowance exceeds any remaining purchase discounts. Once an acquired loan undergoes new underwriting and meets the criteria for a new loan, such as in the case of a loan renewal, any remaining fair value adjustments are accreted into interest income and the loan establishes a new amortized cost basis that is fully subject to the Company's allowance for loan and lease loss methodology. Factored Receivables The Company purchases invoices from its factoring clients in schedules or batches. Cash is advanced to the client to the extent of the applicable advance rate, less fees, as set forth in the individual factoring agreements. The face value of the invoices purchased are recorded by the Company as factored receivables, and the unadvanced portions of the invoices purchased, less fees, are considered client reserves. The client reserves are held to settle any payment disputes or collection shortfalls, may be used to pay clients’ obligations to various third parties as directed by the client, are periodically released to or withdrawn by clients, and are reported as deposits. Unearned factoring fees and unearned net origination fees are deferred and recognized over the weighted average collection period for each client. Subsequent factoring fees are recognized in interest income as incurred by the client and deducted from the clients’ reserve balances. Other factoring-related fees, which include wire transfer fees, carrier payment fees, fuel advance fees, and other similar fees, are reported by the Company as non-interest income as incurred by the client. Loan Commitments and Related Financial Instruments Financial instruments include off-balance sheet credit instruments, such as commitments to make loans and commercial letters of credit, issued to meet customer financing needs. The face amount for these items represents the exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded. Allowance for Loan and Lease Losses The allowance for loan and lease losses (the “ALLL”) is a valuation allowance maintained to cover incurred losses that are estimated in accordance with US GAAP. It is our estimate of credit losses inherent in our loan portfolio at each balance sheet date. Our methodology for analyzing the allowance for loan and lease losses consists of general and specific components. For the general component, we stratify the loan portfolio into homogeneous groups of loans that possess similar loss potential characteristics and apply a loss ratio to these groups of loans to estimate the credit losses in the loan portfolio. We use both historical loss ratios and qualitative loss factors assigned to major loan collateral types to establish general component loss allocations. Qualitative loss factors are based on management's judgment of company, market, industry or business specific data and external economic indicators, which are not yet reflected in the historical loss ratios, and that could impact the Company's loan portfolios. Management sets and adjusts qualitative loss factors by regularly reviewing changes in underlying loan composition of specific portfolios. Management also considers credit quality and trends relating to delinquency, non-performing and adversely rated loans within the Company's loan portfolio when evaluating qualitative loss factors. Additionally, management adjusts qualitative factors to account for the potential impact of external economic factors and other pertinent economic data specific to our primary market area and lending portfolios. For the specific component, the allowance for loan and lease losses includes loans where management has concerns about the borrower's ability to repay and on individually analyzed loans found to be impaired. Management evaluates current information and events regarding a borrower's ability to repay its obligations and considers a loan to be impaired when the ultimate collectability of amounts due, according to the contractual terms of the loan agreement, is in doubt. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. If an impaired loan is collateral-dependent, the fair value of the collateral, less the estimated cost to sell, is used to determine the amount of impairment. If an impaired loan is not collateral-dependent, the impairment amount is determined using the negative difference, if any, between the estimated discounted cash flows and the loan amount due. For impaired loans, the amount of the impairment can be adjusted, based on current data, until such time as the actual basis is established by acquisition of the collateral or until the basis is collected. Impairment losses are reflected in the allowance for loan and lease losses through a charge to the provision for credit losses. Subsequent recoveries are credited to the allowance for loan and lease losses. Cash receipts for accruing loans are applied to principal and interest under the contractual terms of the loan agreement. Cash receipts on impaired loans for which the accrual of interest has been discontinued are applied first to principal. Loan losses are charged against the ALLL when management believes the uncollectability of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the ALLL. Allocations of the ALLL may be made for specific loans, but the entire allowance is available for any loan that, in management’s judgment, should be charged-off. Large groups of smaller balance homogeneous loans are collectively evaluated for impairment, and accordingly, they are not separately identified for impairment disclosures. The Company considers these loans to be homogeneous in nature due to the smaller dollar amount and the similar underwriting criteria. PCI loans are not considered impaired on the acquisition date. For PCI loans, a decline in the present value of current expected cash flows compared to the previously estimated expected cash flows, due in any part to change in credit, is considered an impairment event and a provision for loan losses will be recorded during the period as necessary. A loan that has been modified or renewed is considered a troubled debt restructuring (“TDR”) when two conditions are met: 1) the borrower is experiencing financial difficulty and 2) concessions are made for the borrower's benefit that would not otherwise be considered for a borrower or transaction with similar credit risk characteristics. TDRs are separately identified for impairment and are measured at the present value of estimated future cash flows using the loan’s effective rate at inception. If a TDR is considered to be a collateral dependent loan, the loan is reported, net, at the fair value of the collateral up to the carrying amount of the loan. For TDRs that subsequently default, the Company determines the amount of reserve in accordance with the accounting policy for the ALLL. The following loan portfolio categories have been identified for purposes of determining the general component of the ALLL: Commercial Real Estate — This category of loans consists of the following loan types: Non-farm Non-residential — This category includes real estate loans for a variety of commercial property types and purposes, including owner occupied commercial real estate loans primarily secured by commercial office or industrial buildings, warehouses or retail buildings where the owner of the building occupies the property. Repayment terms vary considerably, interest rates are fixed or variable, and are structured for full, partial, or no amortization of principal. This category also includes investment real estate loans that are primarily secured by office and industrial buildings, warehouses, small retail shopping centers and various special purpose properties. Generally, these types of loans are thought to involve a greater degree of credit risk than owner occupied commercial real estate as they are more sensitive to adverse economic conditions. Multi-family residential — Investment real estate loans are primarily secured by non-owner occupied apartment or multifamily residential buildings. Generally, these types of loans are thought to involve a greater degree of credit risk than owner occupied commercial real estate as they are more sensitive to adverse economic conditions. Construction, land development, land —This category of loans consists of loans to finance the ground up construction, improvement and/or carrying for sale after the completion of construction of owner occupied and non-owner occupied residential and commercial properties, and loans secured by raw or improved land. The repayment of construction loans is generally dependent upon the successful completion of the improvements by the builder for the end user, or sale of the property to a third party. Repayment of land secured loans are dependent upon the successful development and sale of the property, the sale of the land as is, or the outside cash flow of the owners to support the retirement of the debt. 1-4 family residential properties — This category of loans includes both first and junior liens on residential real estate. Home equity revolving lines of credit and home equity term loans are included in this group of loans. Farmland — These loans are principally loans to purchase farmland. Commercial — Commercial loans are loans for commercial, corporate and business purposes. The Company’s commercial business loan portfolio is comprised of loans for a variety of purposes and across a variety of industries. These loans include general commercial and industrial loans, loans to purchase capital equipment, agriculture operating loans and other business loans for working capital and operational purposes. Commercial loans are generally secured by accounts receivable, inventory and other business assets. Commercial loans also include shared national credits purchased by the Company. A portion of the commercial loan portfolio consists of specialty commercial finance products as follows: Equipment — Equipment finance loans are commercial loans primarily secured by new or used revenue producing, essential-use equipment from major manufacturers that is movable, may be used in more than one type of business, and generally has broad resale markets. Core markets include transportation, construction, and waste. Loan terms do not exceed the economic life of the equipment and typically are 60 months or less. Asset-based Lending — These loans are originated to borrowers to support general working capital needs. The asset-based loan structure involves advances of loan proceeds against a borrowing base which typically consists of accounts receivable, identified readily marketable inventory, or other collateral of the borrower. The maximum amount a customer may borrow at any time is fixed as a percentage of the borrowing base outstanding. Premium Finance — Loans that provide customized premium financing solutions for the acquisition of property and casualty insurance coverage. In effect, these short term premium finance loans allow insureds to pay their insurance premiums over the life of the underlying policy, instead of paying the entire premium at the outset. Factored Receivables — The Company operates as a factor by purchasing accounts receivable from its clients, then collecting the receivable from the account debtor. The Company’s smaller factoring relationships are typically structured as “non-recourse” relationships (i.e., the Company retains the credit risk associated with the ability of the account debtor on a purchased invoice to ultimately make payment) and the Company’s larger factoring relationships are typically structured as “recourse” relationships (i.e., the Company’s client agrees to repurchase any invoices for which payment is not ultimately received from the account debtor). Advances initially made to the client to acquire the receivables are typically at a discount to the invoice value. The discount balance is held in client reserves, net of the Company’s compensation. The client reserves are held to settle any payment disputes or collection shortfalls, may be used to pay clients’ obligations to various third parties as directed by the client, are periodically released to or withdrawn by clients, and are reported as deposits. Consumer — Loans used for personal use typically on an unsecured basis. Mortgage Warehouse — Mortgage Warehouse facilities are provided to unaffiliated mortgage origination companies and are collateralized by 1-4 family residential loans. The originator closes new mortgage loans with the intent to sell these loans to third party investors for a profit. The Company provides funding to the mortgage companies for the period between the origination and their sale of the loan. The Company has a policy that requires that it separately validate that each residential mortgage loan was underwritten consistent with the underwriting requirements of the final investor or market standards prior to advancing funds. The Company is repaid with the proceeds received from sale of the mortgage loan to the final investor. Federal Home Loan Bank (“FHLB”) Stock The Company is a member of the FHLB system. Members of the FHLB are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB stock is carried at cost, are restricted as to redemption, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as income. Premises and Equipment Land is carried at cost. Depreciable assets are stated at cost less accumulated depreciation. Leasehold improvements are capitalized and depreciated using the straight-line method over the terms of the respective leases or the estimated useful lives of the improvements, whichever is shorter. Buildings and related components are generally depreciated using the straight-line method with useful lives ranging from thirty to forty years. Furniture, fixtures and equipment are depreciated using the straight-line method with useful lives ranging from three to ten years. Foreclosed Assets Assets acquired through loan foreclosure are initially recorded at the lower of the recorded investment in the loan at the time of foreclosure or the fair value less costs to sell, establishing a new cost basis. Any write-down in the carrying value of a property at the time of acquisition is charged-off to the allowance for loan and lease losses. If fair value declines subsequent to foreclosure, a valuation allowance is recorded through expense. Operating costs after acquisition are expensed. Goodwill Goodwill represents the excess of the cost of businesses acquired over the fair value of the net assets acquired. In accordance with ASC 350-20, "Intangibles- Goodwill and Other", the Company evaluates goodwill for impairment on an annual basis or on an interim basis if an event occurs or circumstances change that would more likely than not reduce the fair value below its carrying amount, in accordance with ASC 350-20. The Company’s annual goodwill impairment testing date is October 1. The Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining the need to perform the two-step test for goodwill impairment (the qualitative method). If the qualitative method cannot be used or if it determines, based on the qualitative method, that the fair value is more likely than not less than the carrying amount, the Company uses the two-step test. Under the two-step test, the Company compares the estimated fair value of a reporting unit with its carrying amount, including goodwill. If the estimated fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is considered not impaired. If the carrying amount of a reporting unit exceeds its estimated fair value, the second step of the goodwill impairment test is performed to measure the amount of impairment loss, if any. Step two of the goodwill impairment test compares the implied estimated fair value of reporting unit goodwill with the carrying amount of that goodwill. If the carrying amount of goodwill for that reporting unit exceeds the implied fair value of that unit’s goodwill, an impairment loss is recognized in an amount equal to that excess. Our annual goodwill impairment test did not identify any goodwill impairment for the years ended December 31, 2017 and 2016. Identifiable Intangible Assets 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 intangible assets primarily relate to core deposits and customer relationships. Intangible assets with definite useful lives are amortized on an accelerated basis over their estimated life. Intangible assets, premises and equipment and other long-lived assets are tested for impairment whenever events or 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 with a charge to amortization of intangible assets. Bank Owned Life Insurance The Company has purchased life insurance policies on certain key employees. The purchase of these life insurance policies allows the Company to use tax-advantaged rates of return. Bank-owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement. Income Taxes The Company files a consolidated tax return with its subsidiaries and is taxed as a C corporation. Deferred tax assets and liabilities are reflected at currently enacted income tax rates applicable to the period in which the deferred tax assets and liabilities are expected to be realized or settled. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. The Company recognizes interest and penalties related to income tax matters in income tax expense. Fair Values of Financial Instruments 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 upon internally developed models that may use, as inputs, observable market-based parameters. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. These adjustments may include amounts to reflect counterparty credit quality and/or the Company’s creditworthiness, among other things, as well as unobservable parameters. Any such valuation adjustments are applied consistently over time. Changes in assumptions or in market conditions could significantly affect these estimates. In the ordinary course of business, the Company generally does not sell or transfer non-impaired loans and deposits. As such, the disclosures that present the December 31, 2017 and 2016 estimated fair value for non-impaired loans and deposits are highly judgmental and may not represent amounts to be received if the Company were to sell or transfer such items. Asset Management Fees On March 31, 2017, the Company sold its membership interests in TCA. At the date of sale, the Company ceased to provide fee based asset management services. Prior to the sale of TCA, asset management fee income was recognized through the Company’s collateralized loan obligation (“CLO”) asset management business operated by TCA and consisted of senior (or base) asset management fees, subordinated management fees, and performance-based incentive fees. Senior and subordinated management fees were based upon a fixed fee rate applied to the amount of outstanding assets being managed by TCA and were accrued by the Company as earned. Performance-based incentive fees were variable in nature and dependent upon the performance of a managed CLO above a prescribed level. The Company did not accrue for performance-based incentive fees that were not finalized until the end of a specified contract period, but recorded such revenues only when final payment was confirmed and related services were completed. The Company did not recognized any revenue that is at risk due to future asset management performance contingencies. TCA also entered into transactions whereby it earned asset management fee income through the provision of middle and back office services to other CLO asset managers. Operating Segments The Company’s reportable segments are comprised of strategic business units primarily based upon industry categories and to a lesser extent, the core competencies relating to product origination, distribution methods, operations and servicing. Segment determination also considered organizational structure and our segment reporting is consistent with the presentation of financial information to the chief operating decision maker to evaluate segment performance, develop strategy, and allocate resources. Our chief operating decision maker is the Chief Executive Officer of Triumph Bancorp, Inc. We have determined our reportable segments are Banking, Factoring, Asset Management, and Corporate. The banking segment includes the operations of TBK Bank. The banking segment derives its revenue principally from investments in interest earning assets as well as noninterest income typical for the banking industry. The banking segment also includes commercial factoring services which are originated through the commercial finance division of TBK Bank. The factoring segment includes the operations of TBC with revenue derived from factoring services. The asset management segment includes the operations of TCA with revenue derived from fees for managing CLO funds and providing middle and back office services to other CLO managers. On March 31, 2017 the Company sold its membership interests in TCA. As a result, the asset management segment had no operations or assets subsequent to March 31, 2017. The corporate segment includes holding company financing and investment activities and management and administrative expenses to support the overall operations of the Company. Comprehensive Income (Loss) Comprehensive income (loss) consists of net income and other comprehensive income (loss). Other comprehensive income includes unrealized gains and losses on securities available for sale, net of taxes, which are also recognized as a separate component of equity. Loss Contingencies Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Management does not believe such matters exist that will have a material effect on the financial statements. Transfers of Financial Assets Transfers of financial assets are accounted for as sales when control over the assets has been relinquished. Control over transferred assets is deemed to be relinquished when (i) the assets have been isolated from the Company, (ii) the transferee has the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (iii) the Company does not maintain effective control over the transferred assets through either (a) an agreement that entitles and obligates the Company to repurchase or redeem them before their maturity or (b) the ability to unilaterally cause the holder to return specific assets. Stock Based Compensation Compensation cost is recognized for stock options and restricted stock awards issued to employees and directors, based on the fair value of these awards at the date of grant. A Black-Scholes model is utilized to estimate the fair value of stock options, while the market price of the Company’s common stock at the date of grant is used for restricted stock awards. Compensation cost is recognized over the required service period, generally defined as the vesting period. Earnings Per Common Share Basic earnings per common share is net income less dividends on preferred stock divided by the weighted average number of common shares outstanding during the period excluding nonvested restricted stock awards. Diluted earnings per common share includes the dilutive effect of additional potential common shares issuable under stock warrants, restricted stock awards, stock options, and preferred shares that are convertible to common shares. Advertising Costs Advertising costs are expensed as incurred. Adoption of New Accounting Standards In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-09, “Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting” (“ASU 2016-09”). The FASB issued this ASU to improve the accounting for share-based payments. ASU 2016-09 simplifies several aspects of the accounting for share-based payment award transactions, including: the presentation of income tax consequences, classification of awards as either equity or liabilities, classification on the statement of cash flows, and calculation of diluted earnings per share. The new standard was effective for the Company on January 1, 2017. Adoption of ASU 2016-09 did not have a material impact on the Company’s financial statements. In March 2017, the FASB issued ASU 2017-08, “Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20), Premium Amortization on Purchased Callable Debt Securities” (“ASU 2017-08”). These amendments shorten the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The guidance is effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. As permitted by the amendment, the Company elected to early adopt the provisions of this ASU as of January 1, 2017. Adoption of ASU 2017-08 did not have a material impact on the Company’s consolidated financial statements. Newly Issued, But Not Yet Effective Accounting Standards In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)” (“ASU 2014-09”), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU replaces most existing revenue recognition guidance in GAAP. The new standard was effective for the Company on January 1, 2018 and management has completed its analysis of the impact of the standard’s adoption. Adoption of the ASU did not have a significant impact on the Company’s consolidated financial statements and related disclosures. The Company’s primary sources of revenue are derived from interest and dividends earned on loans, investment securities, and other financial instruments that are not within the scope of ASU 2014-09. The Company’s revenue recognition pattern for revenue streams within the scope of ASU 2014-09, including but not limited to service charges on deposit accounts and gains/losses on the sale of OREO, did not change significantly from current practice. The standard permits the use of either the full retrospective or modified retrospective transition method. The Company elected to use the modified retrospective transition method which requires application of ASU 2014-09 to uncompleted contracts at the date of adoption however, periods prior to the date of adoption will not be retrospectively revised as the impact of the ASU on uncompleted contracts at the date of adoption was not material. In January 2016, the FASB issued ASU No. 2016-01, “Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities” (“ASU 2016-01”). The guidance affects the accounting for equity investments, financial liabilities under the fair value option and the presentation and disclosure requirements of financial instruments. ASU 2016-01 was effective for the Company on January 1, 2018 and is not expected to have a significant impact on our consolidated financial statements and related disclosures. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)” (“ASU 2016-02”). The FASB issued this ASU to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet by lessees for those leases classified as operating leases under current U.S. GAAP and disclosing key information about leasing arrangements. The amendments in this ASU are effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2018. Early application of this ASU is permitted for all entities. Adoption of ASU 2016-02 is not expected to have a material impact on the Company’s consolidated financial statements. The Company leases certain properties and equipment under operating leases that will result in the recognition of lease assets and lease liabilities on the Company’s balance sheet under the ASU, however, the majority of the Company’s properties and equipment are owned, not leased. At December 31, 2017, the Company had contractual operating lease commitments of approximately $5,969,000, before considering renewal options that are generally present. In June 2016, the FASB issued ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”). Among other things, ASU 2016-13 requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to form their credit loss estimates. Many of the loss estimation techniques applied today will still be permitted, although the inputs to those techniques will change to reflect the full amount of expected credit losses. In addition, ASU 2016-13 amends the accounting for credit losses on debt securities and purchased financial assets with credit deterioration. The amendments in ASU 2016-13 are effective for fiscal years beginning after December 31, 2019, and interim periods within those years for public business entities that are SEC filers. Early adoption is permitted for fiscal years, and interim periods within those years, beginning after December 15, 2018, however, the Company does not currently plan to early adopt the ASU. The Company has formed a cross functional team that is assessing the Company’s data and system needs and evaluating the impact that adoption of this standard will have on the financial condition and results of operations of the Company. In January 2017, the FASB issued ASU 2017-01, “Business Combinations (Topic 805): Clarifying the Definition of a Business,” (“ASU 2017-01”) to improve such definition and, as a result, assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or as business combinations. The definition of a business impacts many areas of accounting including acquisitions, disposals, goodwill and consolidation. ASU 2017-01 was effective for the Company on January 1, 2018 and is to be applied under a prospective approach. The Company expects the adoption of this new guidance to impact the determination of whether future acquisitions are considered a business combination.

NOTE 1 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Operations

Triumph Bancorp, Inc. (collectively with its subsidiaries, “Triumph”, or the “Company” as applicable) is a financial holding company headquartered in Dallas, Texas. The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries Triumph CRA Holdings, LLC (“TCRA”), TBK Bank, SSB (“TBK Bank”), TBK Bank’s wholly owned factoring subsidiary Advance Business Capital LLC, which currently operates under the d/b/a of Triumph Business Capital (“TBC”), and TBK Bank’s wholly owned subsidiary Triumph Insurance Group, Inc. (“TIG”).

On March 31, 2017 the Company sold its membership interest in its wholly owned subsidiary Triumph Capital Advisors, LLC (“TCA”). See Note 2 – Business Combinations and Divestitures for details of the TCA sale and its impact on the Company’s consolidated financial statements.

On January 19, 2018, the Company entered into an agreement to sell the assets (the “Disposal Group”) of Triumph Healthcare Finance (“THF”), and exit its healthcare asset-based lending line of business. THF operates within the TBK Bank, SSB subsidiary. The decision to sell THF was made prior to the end of the year, and at December 31, 2017, the fair value of the Disposal Group exceeded its carrying amount. As a result of this decision, the carrying amount of the Disposal Group was transferred to assets held for sale. See Note 2 – Business Combinations and Divestitures for additional information pertaining to the Disposal Group and the impact of the transaction on the Company’s consolidated financial statements.

Principles of Consolidation and Basis of Presentation

The Company consolidates subsidiaries in which it holds, directly or indirectly, a controlling financial interest. The Company determines whether it has a controlling financial interest in an entity by first evaluating whether the entity is a voting interest entity or a variable interest entity under U.S. generally accepted accounting principles (“GAAP”). Voting interest entities are entities in which the total equity investment at risk is sufficient to enable the entity to finance itself independently and provides the equity holders with the obligation to absorb losses, the right to receive residual returns and the right to make decisions about the entity’s activities. The Company consolidates voting interest entities in which it has at least a majority of the voting interest. Variable interest entities (“VIEs”) are entities that lack one or more of the characteristics of a voting interest entity. A controlling financial interest in a VIE is present when an enterprise has both the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and an obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. The enterprise with a controlling financial interest, known as the primary beneficiary, consolidates the VIE.

In consolidation, all significant intercompany accounts and transactions are eliminated. Investments in unconsolidated entities are accounted for using the equity method of accounting when the Company has the ability to exercise significant influence over operating and financing decisions. Investments that do not meet the criteria for equity method accounting are accounted for using the cost method of accounting.

The accounting and reporting policies of the Company and its subsidiaries conform to GAAP and general practice within the banking industry. Certain reclassifications have been made to prior year amounts to conform to the current year presentation. The Company uses the accrual basis of accounting for financial reporting purposes.

Use of Estimates

To prepare financial statements in conformity with GAAP management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided, and actual results could differ.

Cash and Cash Equivalents

For the purposes of reporting cash flows, cash and cash equivalents include cash on hand, amounts due from banks, other short term investments and federal funds sold. All highly liquid investments with an initial maturity of less than 90 days are considered to be cash equivalents. Certain items, including loan and deposit transactions, customer repurchase agreements, and FHLB advances and repayments, are presented net in the statement of cash flows.

Securities

The Company determines the classification of securities at the time of purchase. Debt securities that management has the positive intent and ability to hold to maturity are classified as held to maturity and recorded at amortized cost. Trading securities are recorded at fair value with changes in fair value included in earnings. Securities not classified as held to maturity or trading are classified as available for sale and recorded at fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive income (loss), net of tax.

Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific-identification method. Amortization of premiums and discounts are recognized in interest income over the period to maturity using the interest method.

Management evaluates securities for other-than-temporary impairment (“OTTI”) on a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. For securities in an unrealized loss position, management considers the extent and duration of the unrealized loss, and the financial condition and near-term prospects of the issuer. Management also assesses whether it intends to sell, or it is more likely than not that it will be required to sell, a security in an unrealized loss position before recovery of its amortized cost basis. In analyzing an issuer’s financial condition, the Company may consider whether the securities are issued by the federal government or its agencies, whether downgrades by bond rating agencies have occurred, and the results of reviews of the issuers’ financial condition. The Company conducts regular reviews of the bond agency ratings of securities and considers whether the securities were issued by or have principal and interest payments guaranteed by the federal government or its agencies. These reviews focus on the underlying rating of the issuer and also include the insurance rating of securities that have an insurance component or guarantee. The ratings and financial condition of the issuers are monitored, as well as the financial condition and ratings of the insurers and guarantors.

If either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost and fair value is recognized as impairment through earnings. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: 1) OTTI related to credit loss, which must be recognized through earnings, and 2) OTTI related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. For equity securities, the entire amount of impairment is recognized through earnings.

Loans Held for Sale

The Company elects the fair value option for recording mortgage loans originated and intended for sale in the secondary market in accordance with Accounting Standards Codification (“ASC”) 825, “Financial Instruments”. The fair value of mortgage loans held for sale is determined based on outstanding commitments from investors to purchase such loans and upon prevailing market rates. Increases or decreases in the fair value of these loans held for sale, if any, are charged to earnings through net gains on sale of loans. Mortgage loans held for sale are generally sold with servicing rights released. Gains and losses on sales of mortgage loans are based on the difference between the final selling price and the fair value of the related loan sold. The Company originated and sold mortgage loans during the years ended December 31, 2016 and 2015 and these activities are reflected in the Consolidated Statements of Income and the Consolidated Statements of Cash Flows for these respective years; however, there were no mortgage loans held for sale carried on the Consolidated Balance Sheets at December 31, 2017 and 2016 as the Company made the decision to exit the residential mortgage production business in the fourth quarter of 2015.

Management occasionally transfers non-mortgage loans from held for investment to held for sale. Gains or losses on the sale of these loans are recorded in noninterest income.

Loans

Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at the unpaid principal balance outstanding, net of unearned income, deferred loan fees and costs, and any direct principal charge-offs. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized in interest income over the remaining life of the loan without anticipating prepayments.

Loans are considered past due or delinquent when the contractual principal or interest due in accordance with the terms of the loan agreement or any portion thereof remains unpaid after the due date of the scheduled payment. Loans are classified as nonaccrual when, in the opinion of management, collection of principal or interest is doubtful. The accrual of interest income on loans is typically discontinued at the time the loan is 90 days delinquent unless the loan is well-secured and in process of collection, or if full collection of interest or principal becomes uncertain. Consumer loans are typically charged off no later than 120 days past due. Past due status is based on the contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged-off at an earlier date if collection of principal or interest is considered doubtful. All interest accrued but not received for a loan placed on nonaccrual is reversed against interest income. Interest received on such loans is accounted for on the cash-basis or cost recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.

Acquired Loans

Acquired loans are recorded at fair value at the date of acquisition with no initial valuation allowance based on a discounted cash flow methodology that considers various factors including the type of loan and related collateral, classification status, fixed or variable interest rate, term of loan and whether or not the loan was amortizing, and a discount rate reflecting the Company’s assessment of risk inherent in the cash flow estimates. Certain larger purchased loans are individually evaluated while certain purchased loans are grouped together according to similar risk characteristics and are treated in the aggregate when applying various valuation techniques. These cash flow evaluations are inherently subjective as they require material estimates, all of which may be susceptible to significant change.

Loans acquired in a business combination that have evidence of deterioration of credit quality since origination and for which it is probable, at acquisition, that the Company will be unable to collect all contractually required payments receivable are considered purchased credit impaired (“PCI”). PCI loans are individually evaluated and recorded at fair value at the date of acquisition with no initial valuation allowance based on a discounted cash flow methodology that considers various factors including the type of loan and related collateral, classification status, fixed or variable interest rate, term of loan and whether or not the loan was amortizing, and a discount rate reflecting the Company’s assessment of risk inherent in the cash flow estimates. The difference between the undiscounted cash flows expected at acquisition and the investment in the loan, or the “accretable yield,” is recognized as interest income on a level-yield method over the life of the loan. Contractually required payments for interest and principal that exceed the undiscounted cash flows expected at acquisition, or the “nonaccretable difference,” are not recognized on the balance sheet and do not result in any yield adjustments, loss accruals or valuation allowances. Increases in expected cash flows, including prepayments, subsequent to the initial investment are recognized prospectively through adjustment of the yield on the loan over its remaining life. Decreases in expected cash flows are recognized as impairment. Valuation allowances on PCI loans reflect only losses incurred after the acquisition (meaning the present value of all cash flows expected at acquisition that ultimately are not to be received).

For acquired loans not deemed credit-impaired at acquisition, the differences between the initial fair value and the unpaid principal balance are recognized as interest income on a level-yield basis over the lives of the related loans. Subsequent to the acquisition date, methods utilized to estimate the required allowance for loan and lease losses for these loans is similar to originated loans; however, a provision for credit losses will be recorded only to the extent the required allowance exceeds any remaining purchase discounts. Once an acquired loan undergoes new underwriting and meets the criteria for a new loan, such as in the case of a loan renewal, any remaining fair value adjustments are accreted into interest income and the loan establishes a new amortized cost basis that is fully subject to the Company's allowance for loan and lease loss methodology.

Factored Receivables

The Company purchases invoices from its factoring clients in schedules or batches. Cash is advanced to the client to the extent of the applicable advance rate, less fees, as set forth in the individual factoring agreements. The face value of the invoices purchased are recorded by the Company as factored receivables, and the unadvanced portions of the invoices purchased, less fees, are considered client reserves. The client reserves are held to settle any payment disputes or collection shortfalls, may be used to pay clients’ obligations to various third parties as directed by the client, are periodically released to or withdrawn by clients, and are reported as deposits.

Unearned factoring fees and unearned net origination fees are deferred and recognized over the weighted average collection period for each client. Subsequent factoring fees are recognized in interest income as incurred by the client and deducted from the clients’ reserve balances.

Other factoring-related fees, which include wire transfer fees, carrier payment fees, fuel advance fees, and other similar fees, are reported by the Company as non-interest income as incurred by the client.

Loan Commitments and Related Financial Instruments

Financial instruments include off-balance sheet credit instruments, such as commitments to make loans and commercial letters of credit, issued to meet customer financing needs. The face amount for these items represents the exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded.

Allowance for Loan and Lease Losses

The allowance for loan and lease losses (the “ALLL”) is a valuation allowance maintained to cover incurred losses that are estimated in accordance with US GAAP. It is our estimate of credit losses inherent in our loan portfolio at each balance sheet date. Our methodology for analyzing the allowance for loan and lease losses consists of general and specific components. For the general component, we stratify the loan portfolio into homogeneous groups of loans that possess similar loss potential characteristics and apply a loss ratio to these groups of loans to estimate the credit losses in the loan portfolio. We use both historical loss ratios and qualitative loss factors assigned to major loan collateral types to establish general component loss allocations. Qualitative loss factors are based on management's judgment of company, market, industry or business specific data and external economic indicators, which are not yet reflected in the historical loss ratios, and that could impact the Company's loan portfolios. Management sets and adjusts qualitative loss factors by regularly reviewing changes in underlying loan composition of specific portfolios. Management also considers credit quality and trends relating to delinquency, non-performing and adversely rated loans within the Company's loan portfolio when evaluating qualitative loss factors. Additionally, management adjusts qualitative factors to account for the potential impact of external economic factors and other pertinent economic data specific to our primary market area and lending portfolios.

For the specific component, the allowance for loan and lease losses includes loans where management has concerns about the borrower's ability to repay and on individually analyzed loans found to be impaired. Management evaluates current information and events regarding a borrower's ability to repay its obligations and considers a loan to be impaired when the ultimate collectability of amounts due, according to the contractual terms of the loan agreement, is in doubt. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. If an impaired loan is collateral-dependent, the fair value of the collateral, less the estimated cost to sell, is used to determine the amount of impairment. If an impaired loan is not collateral-dependent, the impairment amount is determined using the negative difference, if any, between the estimated discounted cash flows and the loan amount due. For impaired loans, the amount of the impairment can be adjusted, based on current data, until such time as the actual basis is established by acquisition of the collateral or until the basis is collected. Impairment losses are reflected in the allowance for loan and lease losses through a charge to the provision for credit losses. Subsequent recoveries are credited to the allowance for loan and lease losses. Cash receipts for accruing loans are applied to principal and interest under the contractual terms of the loan agreement. Cash receipts on impaired loans for which the accrual of interest has been discontinued are applied first to principal.

Loan losses are charged against the ALLL when management believes the uncollectability of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the ALLL. Allocations of the ALLL may be made for specific loans, but the entire allowance is available for any loan that, in management’s judgment, should be charged-off. Large groups of smaller balance homogeneous loans are collectively evaluated for impairment, and accordingly, they are not separately identified for impairment disclosures. The Company considers these loans to be homogeneous in nature due to the smaller dollar amount and the similar underwriting criteria.

PCI loans are not considered impaired on the acquisition date. For PCI loans, a decline in the present value of current expected cash flows compared to the previously estimated expected cash flows, due in any part to change in credit, is considered an impairment event and a provision for loan losses will be recorded during the period as necessary.

A loan that has been modified or renewed is considered a troubled debt restructuring (“TDR”) when two conditions are met: 1) the borrower is experiencing financial difficulty and 2) concessions are made for the borrower's benefit that would not otherwise be considered for a borrower or transaction with similar credit risk characteristics. TDRs are separately identified for impairment and are measured at the present value of estimated future cash flows using the loan’s effective rate at inception. If a TDR is considered to be a collateral dependent loan, the loan is reported, net, at the fair value of the collateral up to the carrying amount of the loan. For TDRs that subsequently default, the Company determines the amount of reserve in accordance with the accounting policy for the ALLL.

The following loan portfolio categories have been identified for purposes of determining the general component of the ALLL:

Commercial Real Estate — This category of loans consists of the following loan types:

Non-farm Non-residential — This category includes real estate loans for a variety of commercial property types and purposes, including owner occupied commercial real estate loans primarily secured by commercial office or industrial buildings, warehouses or retail buildings where the owner of the building occupies the property. Repayment terms vary considerably, interest rates are fixed or variable, and are structured for full, partial, or no amortization of principal. This category also includes investment real estate loans that are primarily secured by office and industrial buildings, warehouses, small retail shopping centers and various special purpose properties. Generally, these types of loans are thought to involve a greater degree of credit risk than owner occupied commercial real estate as they are more sensitive to adverse economic conditions.

Multi-family residential — Investment real estate loans are primarily secured by non-owner occupied apartment or multifamily residential buildings. Generally, these types of loans are thought to involve a greater degree of credit risk than owner occupied commercial real estate as they are more sensitive to adverse economic conditions.

Construction, land development, land —This category of loans consists of loans to finance the ground up construction, improvement and/or carrying for sale after the completion of construction of owner occupied and non-owner occupied residential and commercial properties, and loans secured by raw or improved land. The repayment of construction loans is generally dependent upon the successful completion of the improvements by the builder for the end user, or sale of the property to a third party. Repayment of land secured loans are dependent upon the successful development and sale of the property, the sale of the land as is, or the outside cash flow of the owners to support the retirement of the debt.

1-4 family residential properties — This category of loans includes both first and junior liens on residential real estate. Home equity revolving lines of credit and home equity term loans are included in this group of loans.

Farmland — These loans are principally loans to purchase farmland.

Commercial — Commercial loans are loans for commercial, corporate and business purposes. The Company’s commercial business loan portfolio is comprised of loans for a variety of purposes and across a variety of industries. These loans include general commercial and industrial loans, loans to purchase capital equipment, agriculture operating loans and other business loans for working capital and operational purposes. Commercial loans are generally secured by accounts receivable, inventory and other business assets. Commercial loans also include shared national credits purchased by the Company.

A portion of the commercial loan portfolio consists of specialty commercial finance products as follows:

Equipment — Equipment finance loans are commercial loans primarily secured by new or used revenue producing, essential-use equipment from major manufacturers that is movable, may be used in more than one type of business, and generally has broad resale markets. Core markets include transportation, construction, and waste. Loan terms do not exceed the economic life of the equipment and typically are 60 months or less.

Asset-based Lending — These loans are originated to borrowers to support general working capital needs. The asset-based loan structure involves advances of loan proceeds against a borrowing base which typically consists of accounts receivable, identified readily marketable inventory, or other collateral of the borrower. The maximum amount a customer may borrow at any time is fixed as a percentage of the borrowing base outstanding.

Premium Finance — Loans that provide customized premium financing solutions for the acquisition of property and casualty insurance coverage. In effect, these short term premium finance loans allow insureds to pay their insurance premiums over the life of the underlying policy, instead of paying the entire premium at the outset.

Factored Receivables — The Company operates as a factor by purchasing accounts receivable from its clients, then collecting the receivable from the account debtor. The Company’s smaller factoring relationships are typically structured as “non-recourse” relationships (i.e., the Company retains the credit risk associated with the ability of the account debtor on a purchased invoice to ultimately make payment) and the Company’s larger factoring relationships are typically structured as “recourse” relationships (i.e., the Company’s client agrees to repurchase any invoices for which payment is not ultimately received from the account debtor). Advances initially made to the client to acquire the receivables are typically at a discount to the invoice value. The discount balance is held in client reserves, net of the Company’s compensation. The client reserves are held to settle any payment disputes or collection shortfalls, may be used to pay clients’ obligations to various third parties as directed by the client, are periodically released to or withdrawn by clients, and are reported as deposits.

Consumer — Loans used for personal use typically on an unsecured basis.

Mortgage Warehouse — Mortgage Warehouse facilities are provided to unaffiliated mortgage origination companies and are collateralized by 1-4 family residential loans. The originator closes new mortgage loans with the intent to sell these loans to third party investors for a profit. The Company provides funding to the mortgage companies for the period between the origination and their sale of the loan. The Company has a policy that requires that it separately validate that each residential mortgage loan was underwritten consistent with the underwriting requirements of the final investor or market standards prior to advancing funds. The Company is repaid with the proceeds received from sale of the mortgage loan to the final investor.

Federal Home Loan Bank (“FHLB”) Stock

The Company is a member of the FHLB system. Members of the FHLB are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB stock is carried at cost, are restricted as to redemption, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as income.

Premises and Equipment

Land is carried at cost. Depreciable assets are stated at cost less accumulated depreciation. Leasehold improvements are capitalized and depreciated using the straight-line method over the terms of the respective leases or the estimated useful lives of the improvements, whichever is shorter. Buildings and related components are generally depreciated using the straight-line method with useful lives ranging from thirty to forty years. Furniture, fixtures and equipment are depreciated using the straight-line method with useful lives ranging from three to ten years.

Foreclosed Assets

Assets acquired through loan foreclosure are initially recorded at the lower of the recorded investment in the loan at the time of foreclosure or the fair value less costs to sell, establishing a new cost basis. Any write-down in the carrying value of a property at the time of acquisition is charged-off to the allowance for loan and lease losses. If fair value declines subsequent to foreclosure, a valuation allowance is recorded through expense. Operating costs after acquisition are expensed.

Goodwill

Goodwill represents the excess of the cost of businesses acquired over the fair value of the net assets acquired. In accordance with ASC 350-20, "Intangibles- Goodwill and Other", the Company evaluates goodwill for impairment on an annual basis or on an interim basis if an event occurs or circumstances change that would more likely than not reduce the fair value below its carrying amount, in accordance with ASC 350-20. The Company’s annual goodwill impairment testing date is October 1.

The Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining the need to perform the two-step test for goodwill impairment (the qualitative method). If the qualitative method cannot be used or if it determines, based on the qualitative method, that the fair value is more likely than not less than the carrying amount, the Company uses the two-step test. Under the two-step test, the Company compares the estimated fair value of a reporting unit with its carrying amount, including goodwill. If the estimated fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is considered not impaired. If the carrying amount of a reporting unit exceeds its estimated fair value, the second step of the goodwill impairment test is performed to measure the amount of impairment loss, if any. Step two of the goodwill impairment test compares the implied estimated fair value of reporting unit goodwill with the carrying amount of that goodwill. If the carrying amount of goodwill for that reporting unit exceeds the implied fair value of that unit’s goodwill, an impairment loss is recognized in an amount equal to that excess. Our annual goodwill impairment test did not identify any goodwill impairment for the years ended December 31, 2017 and 2016.

Identifiable Intangible Assets

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 intangible assets primarily relate to core deposits and customer relationships. Intangible assets with definite useful lives are amortized on an accelerated basis over their estimated life. Intangible assets, premises and equipment and other long-lived assets are tested for impairment whenever events or 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 with a charge to amortization of intangible assets.

Bank Owned Life Insurance

The Company has purchased life insurance policies on certain key employees. The purchase of these life insurance policies allows the Company to use tax-advantaged rates of return. Bank-owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement.

Income Taxes

The Company files a consolidated tax return with its subsidiaries and is taxed as a C corporation. Deferred tax assets and liabilities are reflected at currently enacted income tax rates applicable to the period in which the deferred tax assets and liabilities are expected to be realized or settled. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized.

A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. The Company recognizes interest and penalties related to income tax matters in income tax expense.

Fair Values of Financial Instruments

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 upon internally developed models that may use, as inputs, observable market-based parameters. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. These adjustments may include amounts to reflect counterparty credit quality and/or the Company’s creditworthiness, among other things, as well as unobservable parameters. Any such valuation adjustments are applied consistently over time. Changes in assumptions or in market conditions could significantly affect these estimates.

In the ordinary course of business, the Company generally does not sell or transfer non-impaired loans and deposits. As such, the disclosures that present the December 31, 2017 and 2016 estimated fair value for non-impaired loans and deposits are highly judgmental and may not represent amounts to be received if the Company were to sell or transfer such items.

Asset Management Fees

On March 31, 2017, the Company sold its membership interests in TCA. At the date of sale, the Company ceased to provide fee based asset management services. Prior to the sale of TCA, asset management fee income was recognized through the Company’s collateralized loan obligation (“CLO”) asset management business operated by TCA and consisted of senior (or base) asset management fees, subordinated management fees, and performance-based incentive fees. Senior and subordinated management fees were based upon a fixed fee rate applied to the amount of outstanding assets being managed by TCA and were accrued by the Company as earned. Performance-based incentive fees were variable in nature and dependent upon the performance of a managed CLO above a prescribed level. The Company did not accrue for performance-based incentive fees that were not finalized until the end of a specified contract period, but recorded such revenues only when final payment was confirmed and related services were completed. The Company did not recognized any revenue that is at risk due to future asset management performance contingencies.

TCA also entered into transactions whereby it earned asset management fee income through the provision of middle and back office services to other CLO asset managers.

Operating Segments

The Company’s reportable segments are comprised of strategic business units primarily based upon industry categories and to a lesser extent, the core competencies relating to product origination, distribution methods, operations and servicing. Segment determination also considered organizational structure and our segment reporting is consistent with the presentation of financial information to the chief operating decision maker to evaluate segment performance, develop strategy, and allocate resources. Our chief operating decision maker is the Chief Executive Officer of Triumph Bancorp, Inc. We have determined our reportable segments are Banking, Factoring, Asset Management, and Corporate.

The banking segment includes the operations of TBK Bank. The banking segment derives its revenue principally from investments in interest earning assets as well as noninterest income typical for the banking industry. The banking segment also includes commercial factoring services which are originated through the commercial finance division of TBK Bank.

The factoring segment includes the operations of TBC with revenue derived from factoring services.

The asset management segment includes the operations of TCA with revenue derived from fees for managing CLO funds and providing middle and back office services to other CLO managers. On March 31, 2017 the Company sold its membership interests in TCA. As a result, the asset management segment had no operations or assets subsequent to March 31, 2017.

The corporate segment includes holding company financing and investment activities and management and administrative expenses to support the overall operations of the Company.

Comprehensive Income (Loss)

Comprehensive income (loss) consists of net income and other comprehensive income (loss). Other comprehensive income includes unrealized gains and losses on securities available for sale, net of taxes, which are also recognized as a separate component of equity.

Loss Contingencies

Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Management does not believe such matters exist that will have a material effect on the financial statements.

Transfers of Financial Assets

Transfers of financial assets are accounted for as sales when control over the assets has been relinquished. Control over transferred assets is deemed to be relinquished when (i) the assets have been isolated from the Company, (ii) the transferee has the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (iii) the Company does not maintain effective control over the transferred assets through either (a) an agreement that entitles and obligates the Company to repurchase or redeem them before their maturity or (b) the ability to unilaterally cause the holder to return specific assets.

Stock Based Compensation

Compensation cost is recognized for stock options and restricted stock awards issued to employees and directors, based on the fair value of these awards at the date of grant. A Black-Scholes model is utilized to estimate the fair value of stock options, while the market price of the Company’s common stock at the date of grant is used for restricted stock awards. Compensation cost is recognized over the required service period, generally defined as the vesting period.

Earnings Per Common Share

Basic earnings per common share is net income less dividends on preferred stock divided by the weighted average number of common shares outstanding during the period excluding nonvested restricted stock awards. Diluted earnings per common share includes the dilutive effect of additional potential common shares issuable under stock warrants, restricted stock awards, stock options, and preferred shares that are convertible to common shares.

Advertising Costs

Advertising costs are expensed as incurred.

Adoption of New Accounting Standards

In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-09, “Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting” (“ASU 2016-09”). The FASB issued this ASU to improve the accounting for share-based payments. ASU 2016-09 simplifies several aspects of the accounting for share-based payment award transactions, including: the presentation of income tax consequences, classification of awards as either equity or liabilities, classification on the statement of cash flows, and calculation of diluted earnings per share. The new standard was effective for the Company on January 1, 2017. Adoption of ASU 2016-09 did not have a material impact on the Company’s financial statements.

In March 2017, the FASB issued ASU 2017-08, “Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20), Premium Amortization on Purchased Callable Debt Securities” (“ASU 2017-08”). These amendments shorten the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The guidance is effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. As permitted by the amendment, the Company elected to early adopt the provisions of this ASU as of January 1, 2017. Adoption of ASU 2017-08 did not have a material impact on the Company’s consolidated financial statements.

Newly Issued, But Not Yet Effective Accounting Standards

In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)” (“ASU 2014-09”), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU replaces most existing revenue recognition guidance in GAAP. The new standard was effective for the Company on January 1, 2018 and management has completed its analysis of the impact of the standard’s adoption. Adoption of the ASU did not have a significant impact on the Company’s consolidated financial statements and related disclosures. The Company’s primary sources of revenue are derived from interest and dividends earned on loans, investment securities, and other financial instruments that are not within the scope of ASU 2014-09. The Company’s revenue recognition pattern for revenue streams within the scope of ASU 2014-09, including but not limited to service charges on deposit accounts and gains/losses on the sale of OREO, did not change significantly from current practice. The standard permits the use of either the full retrospective or modified retrospective transition method. The Company elected to use the modified retrospective transition method which requires application of ASU 2014-09 to uncompleted contracts at the date of adoption however, periods prior to the date of adoption will not be retrospectively revised as the impact of the ASU on uncompleted contracts at the date of adoption was not material.

In January 2016, the FASB issued ASU No. 2016-01, “Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities” (“ASU 2016-01”). The guidance affects the accounting for equity investments, financial liabilities under the fair value option and the presentation and disclosure requirements of financial instruments. ASU 2016-01 was effective for the Company on January 1, 2018 and is not expected to have a significant impact on our consolidated financial statements and related disclosures.

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)” (“ASU 2016-02”). The FASB issued this ASU to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet by lessees for those leases classified as operating leases under current U.S. GAAP and disclosing key information about leasing arrangements. The amendments in this ASU are effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2018. Early application of this ASU is permitted for all entities. Adoption of ASU 2016-02 is not expected to have a material impact on the Company’s consolidated financial statements. The Company leases certain properties and equipment under operating leases that will result in the recognition of lease assets and lease liabilities on the Company’s balance sheet under the ASU, however, the majority of the Company’s properties and equipment are owned, not leased. At December 31, 2017, the Company had contractual operating lease commitments of approximately $5,969,000, before considering renewal options that are generally present.

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”). Among other things, ASU 2016-13 requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to form their credit loss estimates. Many of the loss estimation techniques applied today will still be permitted, although the inputs to those techniques will change to reflect the full amount of expected credit losses. In addition, ASU 2016-13 amends the accounting for credit losses on debt securities and purchased financial assets with credit deterioration. The amendments in ASU 2016-13 are effective for fiscal years beginning after December 31, 2019, and interim periods within those years for public business entities that are SEC filers. Early adoption is permitted for fiscal years, and interim periods within those years, beginning after December 15, 2018, however, the Company does not currently plan to early adopt the ASU. The Company has formed a cross functional team that is assessing the Company’s data and system needs and evaluating the impact that adoption of this standard will have on the financial condition and results of operations of the Company.

In January 2017, the FASB issued ASU 2017-01, “Business Combinations (Topic 805): Clarifying the Definition of a Business,” (“ASU 2017-01”) to improve such definition and, as a result, assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or as business combinations. The definition of a business impacts many areas of accounting including acquisitions, disposals, goodwill and consolidation. ASU 2017-01 was effective for the Company on January 1, 2018 and is to be applied under a prospective approach. The Company expects the adoption of this new guidance to impact the determination of whether future acquisitions are considered a business combination.
