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 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 16, 2018, the Company sold the assets of Triumph Healthcare Finance (“THF”) and exited its healthcare asset-based lending line of business. THF operated within the Company’s TBK Bank subsidiary. See Note 2 – Business Combinations and Divestitures for details of the THF sale and its impact on our consolidated financial statements. On March 31, 2017 the Company sold its membership interests 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 our consolidated financial statements. Principles of Consolidation and Basis of Presentation The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with United States Generally Accepted Accounting Principles (“GAAP”) for interim financial information and in accordance with guidance provided by the Securities and Exchange Commission. Accordingly, the condensed financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all normal and recurring adjustments considered necessary for a fair presentation. Transactions between the subsidiaries have been eliminated. These condensed consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2017. Operating results for the three months ended March 31, 2018 are not necessarily indicative of the results that may be expected for the year ending December 31, 2018. The Company has three reportable segments consisting of Banking, Factoring, and Corporate. The Company’s Chief Executive Officer uses segment results to make operating and strategic decisions. Revenue from Contracts with Customers The Company records revenue from contracts with customers in accordance with Accounting Standards Codification Topic 606, “Revenue from Contracts with Customers” (“Topic 606”). Under Topic 606, the Company must identify the contract with a customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract, and recognize revenue when (or as) the Company satisfies a performance obligation. Significant revenue has not been recognized in the current reporting period that results from performance obligations satisfied in previous periods. 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 Topic 606. The Company has evaluated the nature of its contracts with customers and determined that further disaggregation of revenue from contracts with customers into more granular categories beyond what is presented in the Consolidated Statements of Income was not necessary. The Company generally fully satisfies its performance obligations on its contracts with customers as services are rendered and the transaction prices are typically fixed; charged either on a periodic basis or based on activity. Because performance obligations are satisfied as services are rendered and the transaction prices are fixed, there is little judgment involved in applying Topic 606 that significantly affects the determination of the amount and timing of revenue from contracts with customers. Income Taxes On December 22, 2017, the United States enacted tax reform legislation commonly known as the Tax Cuts and Jobs Act (the “Tax Act”), resulting in significant modifications to existing law. Authoritative guidance and interpretation by regulatory bodies is ongoing, and as such, the accounting for the effects of the Tax Act is not final and the full impact of the new regulation is still being evaluated. Adoption of New Accounting Standards In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers” (“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. Adoption of ASU 2014-09 did not have a material impact on the Company’s consolidated financial statements and related disclosures as the Company’s primary sources of revenues 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: 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 resulted in separate classification of equity securities previously included in available for sale securities on the consolidated balance sheets with changes in the fair value of the equity securities captured in the consolidated statements of income. See Note 3 – Securities for disclosures related to equity securities. Adoption of the standard also resulted in the use of an exit price rather than an entrance price to determine the fair value of loans not measured at fair value on a non-recurring basis in the consolidated balance sheets. See Note 10 – Fair Value Disclosures for further information regarding the valuation of these loans. 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 business combinations. Newly Issued, But Not Yet Effective Accounting Standards 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 March 31, 2018, the Company had contractual operating lease commitments of approximately $10,222,000, 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.

Business Combinations [Abstract]
Business Combinations and Divestitures	NOTE 2 – Business combinations AND DIVESTITURES Triumph Healthcare Finance 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. At December 31, 2017, the carrying amount of the Disposal Group was transferred to assets held for sale. The sale closed on March 16, 2018. A summary of the carrying amount of the assets in the Disposal Group and the gain on sale is as follows: (Dollars in thousands) Carrying amount of assets in the disposal group: Loans $ 70,147 Premises and equipment, net 19 Goodwill 1,457 Intangible assets, net 958 Other assets 197 Total carrying amount 72,778 Total consideration received 74,017 Gain on sale of division 1,239 Transaction costs 168 Gain on sale of division, net of transaction costs $ 1,071 The Disposal Group was included in the Banking segment, and the loans in the Disposal Group were previously included in the commercial loan portfolio. Valley Bancorp, Inc. Effective December 9, 2017, the Company acquired Valley Bancorp, Inc. (“Valley”) and its community banking subsidiary, Valley Bank & Trust, in an all-cash transaction. Valley Bank & Trust serves individuals and business customers from seven locations across the northern front range including Brighton, Dacono, Denver, Hudson, Westminster and Strasburg, Colorado. Valley Bank & Trust was merged into TBK Bank upon closing. The acquisition expanding the Company’s market in Colorado and further diversified the Company’s loan, customer, and deposit base. A summary of the estimated fair values of assets acquired, liabilities assumed, consideration transferred, and the resulting goodwill is as follows: Initial Values Measurement Recorded at Period Adjusted (Dollars in thousands) Acquisition Date Adjustments Values Assets acquired: Cash and cash equivalents $ 38,473 $ — $ 38,473 Securities 97,687 — 97,687 Loans 171,199 — 171,199 FHLB stock 315 — 315 Premises and equipment 6,238 — 6,238 Other real estate owned 2,282 — 2,282 Intangible assets 6,072 — 6,072 Bank-owned life insurance 7,153 — 7,153 Other assets 1,882 — 1,882 331,301 — 331,301 Liabilities assumed: Deposits 293,398 — 293,398 Junior subordinated debentures 5,470 — 5,470 Other liabilities 2,881 1,680 4,561 301,749 1,680 303,429 Fair value of net assets acquired 29,552 (1,680 ) 27,872 Consideration transferred 40,075 — 40,075 Goodwill $ 10,523 $ 1,680 $ 12,203 The Company has recognized goodwill of $12,203,000, which included a measurement period adjustment for a post-retirement benefit obligation related to an acquired split-dollar bank-owned life insurance policy. Goodwill was calculated as the excess of both the consideration exchanged and the liabilities assumed as compared to the fair value of identifiable net assets acquired and was allocated to the Company’s Banking segment. The goodwill in this acquisition resulted from expected synergies and expansion in the Colorado market. The goodwill will be deducted for tax purposes. The intangible assets recognized in the transaction will be amortized utilizing an accelerated method over their ten year estimated useful lives. The initial accounting for the acquisition has not been completed because the fair values of the assets acquired and liabilities assumed have not yet been finalized. In connection with the acquisition, the Company acquired loans both with and without evidence of credit quality deterioration since origination. The acquired loans were initially recorded at fair value with no carryover of any allowance for loan and lease losses. Acquired loans were segregated between those considered to be purchased credit impaired (“PCI”) loans and those without credit impairment at acquisition. The following table presents details of the estimated fair value of acquired loans at the acquisition date: Loans, Excluding PCI Total (Dollars in thousands) PCI Loans Loans Loans Commercial real estate $ 73,273 $ 254 $ 73,527 Construction, land development, land 19,770 1,199 20,969 1-4 family residential properties 26,264 — 26,264 Farmland 16,934 — 16,934 Commercial 31,893 — 31,893 Factored receivables — — — Consumer 1,612 — 1,612 Mortgage warehouse — — — $ 169,746 $ 1,453 $ 171,199 The operations of Valley are included in the Company’s operating results beginning December 9, 2017.

Independent Bank – Colorado Branches On October 6, 2017, the Company completed its acquisition of nine branch locations in Colorado from Independent Bank Group, Inc.’s banking subsidiary Independent Bank for an aggregate deposit premium of $6,771,000 or 4.2%. The branches were merged into TBK Bank upon closing. The primary purpose of the acquisition was to improve the Company’s core deposit base and continue to build upon the diversification of the Company’s loan portfolio. A summary of the estimated fair values of assets acquired, liabilities assumed, consideration transferred, and the resulting goodwill is as follows: (Dollars in thousands) Assets acquired: Cash and cash equivalents $ 1,611 Loans 95,794 Premises and equipment 7,524 Intangible assets 3,255 Other assets 1,644 109,828 Liabilities assumed: Deposits 160,702 Other liabilities 249 160,951 Fair value of net assets acquired (51,123 ) Cash received from seller, net of $6,771 deposit premium 45,306 Goodwill $ 5,817 The Company has recognized goodwill of $5,817,000, which was calculated as the excess of both the consideration exchanged and the liabilities assumed as compared to the fair value of identifiable net assets acquired and was allocated to the Company’s Banking segment. The goodwill in this acquisition resulted from expected synergies and expansion in the Colorado market. The goodwill will be deducted for tax purposes. The intangible assets recognized in the transaction will be amortized utilizing an accelerated method over their ten year estimated useful lives. The initial accounting for the acquisition has not been completed because the fair values of the assets acquired and liabilities assumed have not yet been finalized. The following table presents details of the estimated fair value of acquired loans at the acquisition date: (Dollars in thousands) Commercial real estate $ 13,382 Construction, land development, land 537 1-4 family residential properties 6,986 Farmland 31,490 Commercial 43,104 Factored receivables — Consumer 295 Mortgage warehouse — $ 95,794 The operations of the branches acquired are included in the Company’s operating results beginning October 6, 2017.

Triumph Capital Advisors, LLC On March 31, 2017, the Company sold its wholly owned asset management subsidiary, Triumph Capital Advisors, LLC, to an unrelated third party. The transaction was completed to enhance shareholder value and provide a platform for TCA to operate without the impact of regulations intended for depository institutions. A summary of the consideration received and the gain on sale is as follows: (Dollars in thousands) Consideration received (fair value): Cash $ 10,554 Loan receivable 10,500 Revenue share 1,623 Total consideration received 22,677 Carrying value of TCA membership interest 1,417 Gain on sale of subsidiary 21,260 Transaction costs 400 Gain on sale of subsidiary, net of transaction costs $ 20,860 The Company financed a portion of the consideration received with a $10,500,000 term credit facility. Terms of the floating rate credit facility provide for quarterly principal and interest payments with an interest rate floor of 5.50%, maturing on March 31, 2023. The Company received a $25,000 origination fee associated with the term credit facility that was deferred and will be accreted over the contractual life of the loan as a yield adjustment. In addition, the Company is entitled to receive an annual earn-out payment representing 3% of TCA’s future annual gross revenue, with a total maximum earn-out amount of $2,500,000. The revenue share earn-out is considered contingent consideration which the Company elected to record as an asset at its estimated fair value of $1,623,000 on the date of sale. The fair value of the revenue share asset was $1,737,000 at March 31, 2018. The Company incurred pre-tax expenses related to the transaction, including professional fees and other direct transaction costs, totaling $400,000 which were netted against the gain on sale of subsidiary in the consolidated statements of income during the three months ended March 31, 2017.

Consideration is given to (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, and (3) the intent and ability of the Company to retain its investment in the security for a period of time sufficient to allow for any anticipated recovery in fair value. At March 31, 2018, the Company had 162 debt securities in an unrealized loss position. Management does not have the intent to sell any of these securities and believes that it is more likely than not that the Company will not have to sell any such securities before a recovery of cost. The fair value is expected to recover as the securities approach their maturity date or repricing date or if market yields for such investments decline. Management does not believe that any of the securities are impaired due to reasons of credit quality. Accordingly, as of March 31, 2018, management believes that the unrealized losses detailed in the previous table are temporary and no other than temporary impairment loss has been recognized in the Company’s consolidated statements of income.

Credit Quality Information The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt, including: current collateral and financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Company analyzes loans individually by classifying the loans as to credit risk on a regular basis. Large groups of smaller balance homogeneous loans, such as consumer loans, are analyzed primarily based on payment status. The Company uses the following definitions for risk ratings: Pass: Loans classified as pass are loans with low to average risk and not otherwise classified as substandard or doubtful. Substandard: Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the repayment of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected. Doubtful: Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. PCI: At acquisition, PCI loans had the characteristics of substandard loans and it was probable, at acquisition, that all contractually required principal and interest payments would not be collected. The Company evaluates these loans on a projected cash flow basis with this evaluation performed quarterly.

Organization Consolidation And Presentation Of Financial Statements [Abstract]
Variable Interest Entities	NOTE 6 – Variable Interest Entities Collateralized Loan Obligation Funds – Closed The Company, through its subsidiary Triumph Capital Advisors, acted as the asset manager or provided certain middle and back office staffing and services to the asset manager of various CLO funds. TCA earned asset management fees in accordance with the terms of its asset management or staffing and services agreements associated with the CLO funds. TCA earned asset management fees totaling $1,717,000 for the three months ended March 31, 2017. On March 31, 2017 the Company sold its membership interests in TCA as discussed in Note 2 – Business Combinations and Divestitures. As a result of the TCA sale, as of March 31, 2017 the Company no longer acted as asset manager or staffing and services provider for any CLO funds. The Company holds investments in the subordinated notes of the following closed CLO funds: Offering Offering (Dollars in thousands) Date Amount Trinitas CLO IV, LTD (Trinitas IV) June 2, 2016 $ 406,650 Trinitas CLO V, LTD (Trinitas V) September 22, 2016 $ 409,000 Trinitas CLO VI, LTD (Trinitas VI) June 20, 2017 $ 717,100 The carrying amounts of the Company’s investments in the subordinated notes of the CLO funds, which represent the Company’s maximum exposure to loss as a result of its involvement with the CLO funds, totaled $8,614,000 and $8,557,000 at March 31, 2018 and December 31, The Company performed a consolidation analysis to confirm whether the Company was required to consolidate the assets, liabilities, equity or operations of the closed CLO funds in its financial statements. The Company concluded that the closed CLO funds were variable interest entities and that the Company holds variable interests in the entities in the form of its investments in the subordinated notes of entities. However, the Company also concluded that the Company does not have the power to direct the activities that most significantly impact the entities’ economic performance. As a result, the Company was not the primary beneficiary and therefore was not required to consolidate the assets, liabilities, equity, or operations of the closed CLO funds in the Company’s financial statements. Collateralized Loan Obligation Funds – Warehouse Phase From time to time, the Company may invest in the subordinated debt of entities formed to be the issuers of CLO offerings during their warehouse phases . The Company’s investments in these CLO funds are repaid when the CLO funds’ warehouse phases are closed and the CLO offerings are issued. The Company’s maximum exposure to loss as a result of its involvement with these CLO funds is limited to the carrying amount of its investments in the subordinated debt of the CLO funds. The Company did not hold any investments in the subordinated debt of CLO funds during their warehouse phase at December 31, 2017 or during the three months ended March 31, 2018. Income from the Company’s investments in CLO warehouse entities totaled $964,000 during the three months ended March 31, 2017, which is included in other noninterest income within the Company’s consolidated statements of income. The Company performed a consolidation analysis of CLO funds during their warehouse phases and concluded that the CLO funds were variable interest entities and that the Company held a variable interest in the entities that could potentially be significant to the entities in the form of its investments in the subordinated notes of the entities. However, the Company also concluded that the Company does not have the power to direct the activities that most significantly impact the entities’ economic performance. As a result, the Company is not the primary beneficiary and therefore is not required to consolidate the assets, liabilities, equity, or operations of the entities in the Company’s financial statements .

Commitments And Contingencies Disclosure [Abstract]
Off-Balance Sheet Loan Commitments	NOTE 9 - OFF-BALANCE SHEET LOAN COMMITMENTS From time to time, the Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit. Those instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the balance sheet. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet financial instruments. The contractual amounts of financial instruments with off-balance sheet risk were as follows: March 31, 2018 December 31, 2017 (Dollars in thousands) Fixed Rate Variable Rate Fixed Rate Variable Rate Unused lines of credit $ 117,111 $ 247,753 $ 133,634 $ 242,236 Standby letters of credit 2,486 8,180 1,998 8,169 Mortgage warehouse commitments 28,530 293,325 9,411 230,221 Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being fully drawn upon, the total commitment amounts disclosed above do not necessarily represent future cash requirements. The Company evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if considered necessary by the Company, upon extension of credit, is based on management’s credit evaluation of the customer. Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. In the event of nonperformance by the customer, the Company has rights to the underlying collateral, which can include commercial real estate, physical plant and property, inventory, receivables, cash and marketable securities. The credit risk to the Company in issuing letters of credit is essentially the same as that involved in extending loan facilities to its customers. Mortgage warehouse commitments are unconditionally cancellable and represent the unused capacity on mortgage warehouse facilities the Company has approved. The Company reserves the right to refuse to buy any mortgage loans offered for sale by a customer, for any reason, at the Company’s sole and absolute discretion. The Company funds an allowance for loan and lease losses on off-balance sheet lending-related commitments through a charge to other noninterest expense on the Company’s consolidated statements of income. At March 31, 2018 and December 31, 2017, the allowance for loan and lease losses on off-balance sheet lending-related commitments totaled $369,000 and $501,000, respectively, and was included in other liabilities on the Company’s consolidated balance sheets. In addition to the commitments above, the Company had overdraft protection available in the amounts of $2,417,000 and $2,397,000 at March 31, 2018 and December 31, 2017, respectively.

Fair Value Disclosures [Abstract]
Fair Value Disclosures	NOTE 10 - Fair Value Disclosures Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair values: Level 1 – Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. Level 2 – Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3 – Significant unobservable inputs that reflect a company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. The methods of determining the fair value of assets and liabilities presented in this note are consistent with our methodologies disclosed in Note 15 of the Company’s 2017 Form 10-K, except for the valuation of loans held for investment which was impact by the adoption of ASU 2016-01. In accordance with ASU 2016-01, the fair value of loans held for investment, excluding previously presented impaired loans measured at fair value on a non-recurring basis, is estimated using discounted cash flow analyses. The discount rates used to determine fair value use interest rate spreads that reflect factors such as liquidity, credit, and nonperformance risk of the loans. Loans are considered a Level 3 classification. Assets measured at fair value on a recurring basis are summarized in the table below. There were no liabilities measured at fair value on a recurring basis at March 31, 2018 and December 31, 2017.

Regulatory Capital Requirements [Abstract]
Regulatory Matters	NOTE 11 - Regulatory Matters The Company (on a consolidated basis) and TBK Bank are subject to various regulatory capital requirements administered by federal and state banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s or TBK Bank’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and TBK Bank must meet specific capital guidelines that involve quantitative measures of their assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. Quantitative measures established by regulation to ensure capital adequacy require the Company and TBK Bank to maintain minimum amounts and ratios (set forth in the table below) of total, common equity Tier 1, and Tier 1 capital to risk weighted assets, and of Tier 1 capital to average assets. Management believes, as of March 31, 2018 and December 31, 2017, the Company and TBK Bank meet all capital adequacy requirements to which they are subject. As of March 31, 2018 and December 31, 2017, TBK Bank’s capital ratios exceeded those levels necessary to be categorized as “well capitalized” under the regulatory framework for prompt corrective action. To be categorized as “well capitalized,” TBK Bank must maintain minimum total risk based, common equity Tier 1 risk based, Tier 1 risk based, and Tier 1 leverage ratios as set forth in the table below. There are no conditions or events since March 31, 2018 that management believes have changed TBK Bank’s category. The actual capital amounts and ratios for the Company and TBK Bank as of March 31, 2018 and December 31, 2017 are presented in the following table.

Beginning in January 2016, the implementation of the capital conservation buffer set forth by the Basel III regulatory capital framework was effective for the company starting at 0.625% of risk weighed assets above the minimum risk based capital ratio requirements and increasing 0.625% each year thereafter, until it reaches 2.5% on January 1, 2019. The capital conservation buffer was 1.875% and 1.25% at March 31, 2018 and December 31, 2017, respectively. The capital conservation buffer is designed to absorb losses during periods of economic stress and requires increased capital levels for the purpose of capital distributions and other payments. Failure to meet the full amount of the buffer will result in restrictions on the Company’s ability to make capital distributions, including dividend payments and stock repurchases, and to pay discretionary bonuses to executive officers. At March 31, 2018 and December 31, 2017, the Company’s and TBK Bank’s risk based capital exceeded the required capital conservation buffer.

Stock Based Compensation	NOTE 13 – STOCK BASED COMPENSATION Stock based compensation expense that has been charged against income was $486,000 and $702,000 for the three months ended March 31, 2018 and 2017, respectively. 2014 Omnibus Incentive Plan The Company’s 2014 Omnibus Incentive Plan (“Omnibus Incentive Plan”) provides for the grant of nonqualified and incentive stock options, stock appreciation rights, restricted stock awards, restricted stock units, and other awards that may be settled in, or based upon the value of, the Company’s common stock. The aggregate number of shares of common stock available for issuance under the Omnibus Incentive Plan is 1,200,000 shares. Restricted Stock Awards A summary of changes in the Company’s nonvested Restricted Stock Awards (“RSAs”) under the Omnibus Incentive Plan for the three months ended March 31, 2018 were as follows: Weighted-Average Grant-Date Nonvested RSAs Shares Fair Value Nonvested at January 1, 2018 102,776 $ 18.68 Granted 5,492 38.50 Vested (5,492 ) 38.50 Forfeited (1,574 ) 20.61 Nonvested at March 31, 2018 101,202 $ 18.65 RSAs granted to employees under the Omnibus Incentive Plan typically vest over three to four years. Compensation expense for RSAs granted under the Omnibus Incentive Program will be recognized over the vesting period of the awards based on the fair value of the stock at the issue date. As of March 31, 2018, there was $572,000 of unrecognized compensation cost related to nonvested RSAs granted under the Omnibus Incentive Plan. The cost is expected to be recognized over a remaining period of 2.74 years. Stock Options A summary of the changes in the Company’s stock options under the Omnibus Incentive Plan as of and for the three months ended March 31, 2018 were as follows: Weighted-Average Remaining Aggregate Weighted-Average Contractual Term Intrinsic Value Stock Options Shares Exercise Price (In Years) (In Thousands) Outstanding at January 1, 2018 185,328 $ 18.97 Granted — — Exercised (374 ) 15.87 Forfeited or expired (3,186 ) 18.98 Outstanding at March 31, 2018 181,768 $ 18.98 8.32 $ 4,039 Fully vested shares and shares expected to vest at March 31, 2018 181,768 $ 18.98 8.32 $ 4,039 Shares exercisable at March 31, 2018 31,368 $ 15.87 8.01 $ 795 Three Months Ended March 31, (Dollars in thousands, except per share amounts) 2018 2017 Aggregate intrinsic value of options exercised $ 10 $ — Cash received from option exercises $ — $ — Tax benefit realized from option exercises $ 2 $ — Weighted average fair value of options granted $ — $ — Stock options awarded to employees under the Omnibus Incentive Plan are generally granted with an exercise price equal to the market price of the Company’s common stock at the date of grant, vest over four years, and have ten year contractual terms. Contractual terms of exercisable options may be shortened due to termination of a participant’s employment. The fair value of stock options granted is estimated at the date of grant using the Black-Scholes option-pricing model. Expected volatilities are determined based on a blend of the Company’s historical volatility and historical volatilities of a peer group of companies with a similar size, industry, stage of life cycle, and capital structure. The expected term of options granted is determined based on the SEC simplified method, which calculates the expected term as the mid-point between the weighted average time to vesting and the contractual term. The risk-free interest rate for the expected term of options is derived from the Treasury constant maturity yield curve on the valuation date. As of March 31, 2018, there was $387,000 of unrecognized compensation cost related to nonvested stock options granted under the Omnibus Incentive Plan. The cost is expected to be recognized over a remaining period of 2.62 years.

Segment Reporting [Abstract]
Business Segment Information	NOTE 15 – BUSINESS SEGMENT INFORMATION The following table presents the Company’s operating segments. The accounting policies of the segments are substantially similar to those described in the “Summary of Significant Accounting Policies” in Note 1 of the Company’s 2017 Form 10-K. Transactions between segments consist primarily of borrowed funds. Intersegment interest expense is allocated to the Factoring segment based on the Company’s prime rate. The provision for loan loss is allocated based on the segment’s allowance for loan loss determination. Noninterest income and expense directly attributable to a segment are assigned to it. Taxes are paid on a consolidated basis but not allocated for segment purposes. The Factoring segment includes only factoring originated by TBC. General factoring services not originated through TBC are included in the Banking segment. On March 31, 2017, the Company sold its 100% membership interest in Triumph Capital Advisors, LLC (“TCA”) and discontinued fee based asset management services. TCA operations were not material during the year ended December 31, 2017 and are reflected in the Corporate segment, along with the gain on sale of the Company’s membership interest in TCA.

Summary of Significant Accoun24

Summary of Significant Accounting Policies (Policies)	3 Months Ended

Accounting Policies [Abstract]
Nature of Operations	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 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 16, 2018, the Company sold the assets of Triumph Healthcare Finance (“THF”) and exited its healthcare asset-based lending line of business. THF operated within the Company’s TBK Bank subsidiary. See Note 2 – Business Combinations and Divestitures for details of the THF sale and its impact on our consolidated financial statements. On March 31, 2017 the Company sold its membership interests 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 our consolidated financial statements.
Principles of Consolidation and Basis of Presentation	Principles of Consolidation and Basis of Presentation The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with United States Generally Accepted Accounting Principles (“GAAP”) for interim financial information and in accordance with guidance provided by the Securities and Exchange Commission. Accordingly, the condensed financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all normal and recurring adjustments considered necessary for a fair presentation. Transactions between the subsidiaries have been eliminated. These condensed consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2017. Operating results for the three months ended March 31, 2018 are not necessarily indicative of the results that may be expected for the year ending December 31, 2018. The Company has three reportable segments consisting of Banking, Factoring, and Corporate. The Company’s Chief Executive Officer uses segment results to make operating and strategic decisions.
Revenue from Contracts with Customers	Revenue from Contracts with Customers The Company records revenue from contracts with customers in accordance with Accounting Standards Codification Topic 606, “Revenue from Contracts with Customers” (“Topic 606”). Under Topic 606, the Company must identify the contract with a customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract, and recognize revenue when (or as) the Company satisfies a performance obligation. Significant revenue has not been recognized in the current reporting period that results from performance obligations satisfied in previous periods. 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 Topic 606. The Company has evaluated the nature of its contracts with customers and determined that further disaggregation of revenue from contracts with customers into more granular categories beyond what is presented in the Consolidated Statements of Income was not necessary. The Company generally fully satisfies its performance obligations on its contracts with customers as services are rendered and the transaction prices are typically fixed; charged either on a periodic basis or based on activity. Because performance obligations are satisfied as services are rendered and the transaction prices are fixed, there is little judgment involved in applying Topic 606 that significantly affects the determination of the amount and timing of revenue from contracts with customers.
Income Taxes	Income Taxes On December 22, 2017, the United States enacted tax reform legislation commonly known as the Tax Cuts and Jobs Act (the “Tax Act”), resulting in significant modifications to existing law. Authoritative guidance and interpretation by regulatory bodies is ongoing, and as such, the accounting for the effects of the Tax Act is not final and the full impact of the new regulation is still being evaluated.
Adoption of New Accounting Standards	Adoption of New Accounting Standards In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers” (“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. Adoption of ASU 2014-09 did not have a material impact on the Company’s consolidated financial statements and related disclosures as the Company’s primary sources of revenues 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: 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 resulted in separate classification of equity securities previously included in available for sale securities on the consolidated balance sheets with changes in the fair value of the equity securities captured in the consolidated statements of income. See Note 3 – Securities for disclosures related to equity securities. Adoption of the standard also resulted in the use of an exit price rather than an entrance price to determine the fair value of loans not measured at fair value on a non-recurring basis in the consolidated balance sheets. See Note 10 – Fair Value Disclosures for further information regarding the valuation of these loans. 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 business combinations.
Newly Issued But Not Yet Effective Accounting Standards	Newly Issued, But Not Yet Effective Accounting Standards 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 March 31, 2018, the Company had contractual operating lease commitments of approximately $10,222,000, 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.
