Accounting Policies [Abstract]
Summary of Significant Accounting Policies	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”), TBK Bank’s wholly owned subsidiary Triumph Insurance Group, Inc. (“TIG”). TriumphPay operates as a division of TBK Bank, SSB. 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 (“SEC”). 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, 2020. Operating results for the three and nine months ended September 30, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021. 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 is consistent with the presentation of financial information to the chief operating decision maker to evaluate segment performance, develop strategy, and allocate resources. The Company's chief operating decision maker is the Chief Executive Officer of Triumph Bancorp, Inc. Management has determined that the Company has four reportable segments consisting of Banking, Factoring, Payments, 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 Factoring segment includes the operations of TBC with revenue derived from factoring services. The Payments segment includes the operations of the TBK Bank's TriumphPay division, which is the payments network for trucking; creating frictionless presentment, audit, and payment of invoices. The Payments segment derives its revenue from transaction fees and interest income on factored receivables related to invoice payments. These factored receivables consist of both invoices where we offer a carrier a QuickPay opportunity to receive payment at a discount in advance of the standard payment term for such invoice in exchange for the assignment of such invoice to us and from offering freight brokers the ability to settle their invoices with us on an extended term following our payment to their carriers as an additional liquidity option for such freight brokers. The corporate segment includes holding company financing and investment activities and management and administrative expenses to support the overall operations of the Company. Prior to June 30, 2021, management determined that the Company had three reportable segments consisting of Banking, Factoring, and Corporate, and the Banking segment included the operations of TBK Bank and TriumphPay. On June 1, 2021, TriumphPay acquired HubTran, Inc., a cloud-based provider of automation software for the trucking industry’s back office (see Note 2 – Business Combinations and Divestitures for further disclosures regarding the acquisition of HubTran). The acquisition of HubTran allows TriumphPay to create a fully integrated payments network for trucking; servicing brokers and factors. TriumphPay already offered tools and services to increase automation, mitigate fraud, create back-office efficiency and improve the payment experience. Through the acquisition of HubTran, TriumphPay created additional value through the enhancement of its presentment, audit, and payment capabilities for shippers, third party logistics companies (i.e., freight brokers) and their carriers, and factors. The acquisition of HubTran was a meaningful inflection point in the operations of TriumphPay as the TriumphPay strategy has shifted from a capital-intensive on-balance sheet product with a focus on interest income to a payments network for the trucking industry with a focus on fee revenue. In terms of total revenue, operating income (loss), and total assets, TriumphPay is currently, and has historically been, quantitatively immaterial; however, given the shift in strategy brought on by the acquisition of HubTran as well as significant management and chief operating decision maker focus on TriumphPay operations, management believes disclosing TriumphPay's operations through the Payments segment is qualitatively useful for readers of these financial statements. This change also brings the Company's reportable segments in line with its reporting units used for goodwill impairment evaluation. Prior to the acquisition of HubTran, the Payments reporting unit carried no goodwill. Prior period business segment disclosures have been revised as appropriate to reflect the current period change in reportable segments. Risks and Uncertainties Significant progress has been made to combat the outbreak of COVID-19; however, the global pandemic has adversely impacted a broad range of industries in which the Company's customers operate and could still impair their ability to fulfill their financial obligations to the Company. The Company’s business is dependent upon the willingness and ability of its employees and customers to conduct banking and other financial transactions. While it appears that the epidemiological and macroeconomic conditions are trending in a positive direction as of September 30, 2021, if there is a resurgence in the virus, the Company could experience further adverse effects on its business, financial condition, results of operations and cash flows. While it is not possible to know the full universe or extent that the impact of COVID-19, and any potential resulting measures to curtail its spread, will have on the Company's future operations, the Company is disclosing potentially material items of which it is aware. Financial position and results of operations The Company’s interest income could be reduced due to COVID-19. In keeping with guidance from regulators, the Company continues to work with COVID-19 affected borrowers to defer their payments, interest, and fees. While interest and fees continue to accrue to income through normal GAAP accounting, should eventual credit losses on these deferred payments emerge, the related loans would be placed on nonaccrual status and interest income and fees accrued would be reversed. In such a scenario, interest income in future periods could be negatively impacted. As of September 30, 2021 the Company carries $121,000 of accrued interest income and fees on outstanding deferrals made to COVID-19 affected borrowers. At this time, the Company is unable to project the materiality of such an impact on future deferrals to COVID-19 affected borrowers, but recognizes the breadth of the economic impact may affect its borrowers’ ability to repay in future periods. Capital and liquidity The Company's reported and regulatory capital ratios could be adversely impacted by further credit loss expense. The Company relies on cash on hand as well as dividends from its subsidiary bank to service its debt. If the Company's capital deteriorates such that its subsidiary bank is unable to pay dividends to the Company for an extended period of time, the Company may not be able to service its debt. The Company maintains access to multiple sources of liquidity. Wholesale funding markets have remained open to the Company, but rates for short-term funding can be volatile. If funding costs are elevated for an extended period of time, it could have an adverse effect on the Company's net interest margin. If an extended recession caused large numbers of the Company's deposit customers to withdraw their funds, the Company might become more reliant on volatile or more expensive sources of funding. Intangible asset valuation The lingering effects COVID-19 could cause a decline in the Company’s stock price or the occurrence of what management would deem to be a triggering event that could, under certain circumstances, cause us to perform a goodwill impairment test and result in an impairment charge being recorded for that period. In the event that the Company concludes that all or a portion of its goodwill is impaired, a non-cash charge for the amount of such impairment would be recorded to earnings. Such a charge would have no impact on tangible capital or regulatory capital. It is possible that the lingering effects of COVID-19 could cause the occurrence of what management would deem to be a triggering event that could, under certain circumstances, cause us to perform an intangible asset impairment test and result in an impairment charge being recorded for that period. In the event that the Company concludes that all or a portion of its intangible assets are impaired, a non-cash charge for the amount of such impairment would be recorded to earnings. Such a charge would have no impact on tangible capital or regulatory capital. Lending operations and accommodations to borrowers In keeping with regulatory guidance to work with borrowers during this unprecedented situation and as outlined in the Section 4013 of the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) , the Company is executing a payment deferral program for its commercial lending clients that are adversely affected by the pandemic. Depending on the demonstrated need of the client, the Company is deferring either the full loan payment or the principal component of the loan payment for a stated period of time. As of September 30, 2021, the Company’s balance sheet reflected 3 of these deferrals on outstanding loan balances of $32,220,000. In accordance with the CARES Act and March 2020 interagency guidance, these deferrals are not considered troubled debt restructurings. It is possible that these deferrals could be extended further under the CARES Act; however, the volume of these future potential extensions is unknown. It is also possible that in spite of the Company's best efforts to assist its borrowers and achieve full collection of the Company's investment, these deferred loans could result in future charge-offs with additional credit loss expense charged to earnings; however, the amount of any future charge-offs on deferred loans is unknown. At September 30, 2021, 94% of the $32,220,000 COVID deferral balance was made up of one relationship. With the passage of the Paycheck Protection Program (“PPP”), administered by the Small Business Administration (“SBA”), the Company has participated in assisting its customers with applications for resources through the program. PPP loans have two-year and five-year terms and earn interest at a 1% coupon. The Company believes that the majority of these loans will ultimately be forgiven by the SBA in accordance with the terms of the program. As of September 30, 2021, the Company carried 815 PPP loans representing a book value of $87,413,000. The Company recognized $1,584,000 and $4,524,000 in fees from the SBA on PPP loans during the three and nine months ended September 30, 2021 and carried $3,580,000 of deferred fees on PPP loans at September 30, 2021. The remaining fees will be amortized and recognized over the remaining lives of the loans. It is the Company’s understanding that loans funded through the PPP program are fully guaranteed by the U.S. government. Should those circumstances change, the Company could be required to establish an allowance for credit loss through additional credit loss expense charged to earnings. Credit The Company is working with customers directly affected by COVID-19. The Company is prepared to offer assistance in accordance with regulator guidelines. As a result of the current economic environment caused by the COVID-19 virus, the Company is engaging in communication with borrowers to understand their situation and the challenges faced, allowing the Company to respond proactively as needs and issues arise. Should the economy experience a prolonged period of poor economic conditions or should economic conditions worsen, the Company could experience increases in its required allowance for credit losses (“ACL”) and record additional credit loss expense. It is possible that the Company’s asset quality measures could worsen at future measurement periods if the effects of COVID-19 are prolonged.

Business Combinations [Abstract]
Business Combinations and Divestitures	BUSINESS COMBINATIONS AND DIVESTITURES HubTran Inc. On June 1, 2021, the Company, through TriumphPay, a division of the Company's wholly-owned subsidiary TBK Bank, SSB, acquired HubTran, Inc. ("HubTran"), a cloud-based provider of automation software for the trucking industry's back-office. A summary of the estimated fair values of assets acquired, liabilities assumed, consideration transferred, and the resulting goodwill is as follows: (Dollars in thousands) Initial Values Measurement Period Adjustments Adjusted Values Assets acquired: Cash $ 170 $ — $ 170 Intangible assets - capitalized software 16,932 — 16,932 Intangible assets - customer relationship 10,360 — 10,360 Other assets 1,546 24 1,570 29,008 24 29,032 Liabilities assumed: Deferred income taxes 4,703 (3,230) 1,473 Other liabilities 906 16 922 5,609 (3,214) 2,395 Fair value of net assets acquired $ 23,399 $ 3,238 $ 26,637 Consideration: Cash paid $ 97,096 $ — $ 97,096 Goodwill $ 73,697 $ (3,238) $ 70,459 The Company has recognized goodwill of $70,459,000, which included measurement period adjustments related to customary settlement adjustments and the finalization of the HubTran stub period tax return and its impact on the acquired deferred tax liability. Goodwill was calculated as the excess of the fair value of consideration exchanged as compared to the fair value of identifiable net assets acquired and was allocated to the Company’s Payments segment. The goodwill in this acquisition resulted from expected synergies and progress in the development of a fully integrated open loop payments network for the transportation industry. The goodwill will not be deducted for tax purposes. 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 intangible assets recognized include a capitalized software intangible asset with an acquisition date fair value of $16,932,000 which will be amortized on a straight-line basis over its four year estimated useful life and a customer relationship intangible asset with an acquisition date fair value of $10,360,000 which will be amortized utilizing an accelerated method over its eleven year estimated useful life. Revenue and earnings of HubTran since the acquisition date have not been disclosed as the acquired company was merged into the Company and separate financial information is not readily available. Expenses related to the acquisition, including professional fees and other transaction costs, totaling $2,992,000 were recorded in noninterest expense in the consolidated statements of income during the three months ended June 30, 2021. Transportation Financial Solutions On July 8, 2020, the Company, through its wholly-owned subsidiary Advance Business Capital LLC (“ABC”), acquired the transportation factoring assets (the “TFS Acquisition”) of Transport Financial Solutions (“TFS”), a wholly owned subsidiary of Covenant Logistics Group, Inc. ("CVLG"), in exchange for cash consideration of $108,375,000, 630,268 shares of the Company’s common stock valued at approximately $13,942,000, and contingent consideration of up to approximately $9,900,000 to be paid in cash following the twelve-month period ending July 31, 2021. Subsequent to the closing of the TFS Acquisition, the Company identified that approximately $62,200,000 of the assets acquired at closing were advances against future payments to be made to three large clients (and their affiliated entities) of TFS pursuant to long-term contractual arrangements between the obligor on such contracts and such clients (and their affiliated entities) for services that had not yet been performed. On September 23, 2020, the Company and ABC entered into an Account Management Agreement, Amendment to Purchase Agreement and Mutual Release (the “Agreement”) with CVLG and Covenant Transport Solutions, LLC, a wholly owned subsidiary of CVLG ( “CTS” and, together with CVLG, "Covenant"). Pursuant to the Agreement, the parties agreed to certain amendments to that certain Accounts Receivable Purchase Agreement (the “ARPA”), dated as of July 8, 2020, by and among ABC, as buyer, CTS, as seller, and the Company, as buyer indirect parent. Such amendments include: • Return of the portion of the purchase price paid under the ARPA consisting of 630,268 shares of Company common stock, which will be accomplished through the sale of such shares by Covenant pursuant to the terms of the Agreement and the surrender of the cash proceeds of such sale (net of brokerage or underwriting fees and commissions) to the Company; • Elimination of the earn-out consideration potentially payable to CTS under the ARPA; and • Modification of the indemnity provisions under the ARPA to eliminate the existing indemnifications for breaches of representations and warranties and to replace such with a newly established indemnification by Covenant in the event ABC incurs losses related to the $62,200,000 in over-formula advances made to specified clients identified in the Agreement (the “Over-Formula Advance Portfolio”). Under the terms of the new indemnification arrangement, Covenant will be responsible for and will indemnify ABC for 100% of the first $30,000,000 of any losses incurred by ABC related to the Over-Formula Advance Portfolio, and for 50% of the next $30,000,000 of any losses incurred by ABC, for total indemnification by Covenant of $45,000,000. Covenant’s indemnification obligations under the Agreement were secured by a pledge of equipment collateral by Covenant with an estimated net orderly liquidation value of $60,000,000 (the “Equipment Collateral”). The Company’s wholly-owned bank subsidiary, TBK Bank, SSB, has provided Covenant with a $45,000,000 line of credit, also secured by the Equipment Collateral, the proceeds of which may be drawn to satisfy Covenant’s indemnification obligations under the Agreement. Pursuant to the Agreement, Triumph and Covenant have agreed to certain terms related to the management of the Over-Formula Advance Portfolio, and the terms by which Covenant may provide assistance to maximize recovery on the Over-Formula Advance Portfolio. Pursuant to the Agreement, the Company and Covenant have provided mutual releases to each other related to any and all claims related to the transactions contemplated by the ARPA or the Over-Formula Advance Portfolio. The measurement period for this transaction remained open at the time the Agreement was executed, and the Company determined that there is a clear and direct link between the Agreement and the ARPA. Therefore, the terms of the Agreement were incorporated into the Company's purchase accounting which resulted in the elimination of the contingent consideration component of the ARPA, the recognition of cash due from Covenant as part of the consideration for the transaction, and an indemnification asset to reflect the modification of Covenant's indemnification obligations. A summary of the estimated fair values of assets acquired, liabilities assumed, consideration transferred, and the resulting goodwill is as follows: (Dollars in thousands) Initial Values Recorded at Acquisition Date Measurement Period Adjustments Adjusted Values Assets acquired: Factored receivables $107,524 $— $107,524 Allowance for credit losses (37,415) — (37,415) Factored receivables, net of ACL 70,109 — 70,109 Intangible assets 3,500 — 3,500 Indemnification asset 30,959 — 30,959 Deferred income taxes 1,448 (59) 1,389 106,016 (59) 105,957 Liabilities assumed: Deposits 5,361 — 5,361 5,361 — 5,361 Fair value of net assets acquired $100,655 $ (59) $100,596 Consideration: Cash paid $108,375 — $108,375 Stock consideration 13,942 — 13,942 Cash due from seller subsequent to liquidation of stock consideration (17,196) — (17,196) Total consideration $105,121 $— $105,121 Goodwill $4,466 $59 $4,525 The Company recognized goodwill of $4,525,000, which included measurement period adjustments related to the finalization of the tax basis of Covenant’s customer intangibles and its impact on the deferred tax liability associated with these intangibles. Goodwill was calculated as the excess of the fair value of consideration exchanged as compared to the fair value of identifiable net assets acquired and was allocated to the Company’s Factoring segment. The goodwill in this acquisition resulted from expected synergies and expansion in the factoring market. The goodwill will not be deducted for tax purposes. Consideration included cash due from Covenant subsequent to liquidation of the stock consideration with an acquisition date fair value of $17,196,000. The fair value of cash due from Covenant was based on the Company's stock price on the date of the Agreement, less an estimate of broker commissions and discounts. During the year ended December 31, 2020, the entirety of the acquired stock was sold by Covenant, Covenant delivered net proceeds of $28,064,000, and the Company recognized $10,868,000 of other noninterest income measured as the difference between the initial purchase accounting measurement and the amount of net proceeds delivered to the Company upon liquidation. Of the total $10,868,000 of noninterest income recognized, $2,007,000 was recognized during the three months ended September 30, 2020, and the remainder was recognized during the three months ended December 31, 2020. The intangible assets recognized include a customer relationship intangible asset with an acquisition date fair value of $3,500,000 which will be amortized utilizing an accelerated method over its eight year estimated useful life. The indemnification asset was measured separately from the related covered portfolio. It is not contractually embedded in the covered portfolio nor is it transferable with the covered portfolio should the Company choose to dispose of the portfolio or a portion of the portfolio. The indemnification asset was initially recorded in other assets in the Consolidated Balance Sheets at the time of the TFS Acquisition at a fair value of $30,959,000, measured as the present value of the estimated cash payments expected to be received from Covenant for probable losses on the covered Over-Formula Advance Portfolio. These cash flows were discounted at a rate to reflect the uncertainty of the timing and receipt of the payments from Covenant . The amount ultimately collected for this asset will be dependent upon the performance of the underlying covered portfolio, the passage of time, and Covenant's willingness and ability to make necessary payments. The terms of the Agreement are such that indemnification has no expiration date and the Company will continue to carry the indemnification asset until ultimate resolution of the covered portfolio. The indemnification asset is reviewed quarterly and changes to the asset are recorded as adjustments to other noninterest income, as appropriate, within the Consolidated Statements of Income. The value of the indemnification asset was $4,786,000 and $36,225,000 at September 30, 2021 and December 31, 2020, respectively. During the three months ended March 31, 2021, new adverse developments with the largest of the three Over-Formula Advance clients caused the Company to charge-off the entire Over-Formula Advance amount due from that client. This resulted in a net charge-off of $41,265,000; however, this net charge-off had no impact on credit loss expense for the three months ended March 31, 2021 as the entire amount had been reserved in a prior period. In accordance with the Agreement reached with Covenant, Covenant reimbursed the Company for $35,633,000 of this charge-off by drawing on its secured line of credit, which was reflected on the Company's March 31, 2021 Consolidated Balance Sheet as a current and performing equipment loan held for investment. Given separate developments with the other two Over-Formula Advance clients, the Company reserved an additional $2,844,000 reflected in credit loss expense for the three months ended March 31, 2021. The $2,844,000 increase in required ACL as well as accretion of most of the fair value discount on the indemnification asset held at December 31, 2020 resulted in a $4,654,000 gain on the indemnification asset which was recorded through non-interest income. Since March 31, 2021, Covenant has paid down its secured line of credit with TBK in its entirety and carries no outstanding balance at September 30, 2021. At September 30, 2021, Covenant had remaining availability of $9,361,000 on its TBK line of credit available to cover our indemnification balance of up to $5,038,000. During the three months ended September 30, 2021, there were no material changes in the underlying credit quality of the remaining two Over-Formula Advance clients. As such, there were no charge-offs related to these balances and no material adjustments were made to the corresponding ACL balances or the indemnification asset during that period. The contractually required payments and the fair value at acquisition of factored receivables purchased for which there was not, at acquisition, evidence of more than insignificant deterioration of credit quality since origination (non-PCD loans) totaled $45,228,000 and $44,962,000, respectively. Management determined that the $62,200,000 in Over-Formula Advances obtained through the TFS Acquisition had experienced more than insignificant credit deterioration since origination and thus, deemed those Over-Formula Advances to be purchased credit deteriorated ("PCD"). Other, less significant factored receivables were also considered to be PCD. The following table presents information at the acquisition date for factored receivables purchased for which there was, at acquisition, evidence of more than insignificant deterioration of credit quality since origination: (Dollars in thousands) Purchase price of loans at acquisition $25,147 Allowance for credit losses at acquisition 37,415 Non-credit discount/(premium) at acquisition 941 Par value of acquired loans at acquisition $63,503 Revenue and earnings of TFS since the acquisition date have not been disclosed as the acquired company was merged into the Company and separate financial information is not readily available. Expenses related to the acquisition, including professional fees and other transaction costs, totaling $827,000 were recorded in noninterest expense in the consolidated statements of income during the three months ended September 30, 2020. Triumph Premium Finance On April 20, 2020, the Company entered into an agreement to sell the assets (the “Disposal Group”) of Triumph Premium Finance (“TPF”) and exit its premium finance line of business. The decision to sell TPF was made during the three months ended March 31, 2020, and at March 31, 2020, the carrying amount of the Disposal Group was transferred to assets held for sale. The sale closed on June 30, 2020. 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 $ 84,504 Premises and equipment, net 45 Other assets 11 84,560 Carrying amount of liabilities in the disposal group: Other liabilities 479 Total carrying amount $ 84,081 Total consideration received 94,531 Gain on sale of division 10,450 Transaction costs 692 Gain on sale of division, net of transaction costs $ 9,758 The Disposal Group was included in the Banking segment, and the loans in the Disposal Group were previously included in the commercial loan portfolio.

Accrued interest on available for sale securities totaled $776,000 and $1,233,000 at September 30, 2021 and December 31, 2020, respectively, and was included in other assets in the consolidated balance sheets. There was no accrued interest related to debt securities reversed against interest income for the three and nine months ended September 30, 2021 and 2020.

Consideration is given to (1) the extent to which the fair value is 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 September 30, 2021, the Company had 12 available for sale debt securities in an unrealized loss position without an allowance for credit losses. 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. Accordingly, as of September 30, 2021, management believes that the unrealized losses detailed in the previous table are due to noncredit-related factors, including changes in interest rates and other market conditions, and therefore no losses have been recognized in the Company’s consolidated statements of income. The following table presents the activity in the allowance for credit losses for held to maturity debt securities: (Dollars in thousands) Three Months Ended September 30, Nine Months Ended September 30, Held to Maturity CLO Securities 2021 2020 2021 2020 Allowance for credit losses: Beginning balance $ 1,727 $ 1,855 $ 2,026 $ — Impact of adopting ASC 326 — — — 126 Credit loss expense 10 106 (289) 1,835 Allowance for credit losses ending balance $ 1,737 $ 1,961 $ 1,737 $ 1,961 The Company’s held to maturity securities are investments in the unrated subordinated notes of collateralized loan obligation funds. These securities are the junior-most in securitization capital structures, and are subject to suspension of distributions if the credit of the underlying loan portfolios deteriorates materially. The ACL on held to maturity securities is estimated at each measurement date on a collective basis by major security type. At September 30, 2021 and December 31, 2020, the Company’s held to maturity securities consisted of three investments in the subordinated notes of collateralized loan obligation (“CLO”) funds. Expected credit losses for these securities are estimated using a discounted cash flow methodology which considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. Ultimately, the realized cash flows on CLO securities such as these will be driven by a variety of factors, including credit performance of the underlying loan portfolio, adjustments to the portfolio by the asset manager, and the timing of a potential call. As of September 30, 2021, $5,810,000 of the Company’s held to maturity securities were classified as nonaccrual.

Accrued interest on loans, which is excluded from the amortized cost of loans held for investment, totaled $15,235,000 and $18,198,000 at September 30, 2021 and December 31, 2020, respectively, and was included in other assets in the consolidated balance sheets. At September 30, 2021 and December 31, 2020, the Company had $189,565,000 and $145,892,000, respectively, of customer reserves associated with factored receivables. These amounts represent customer reserves held to settle any payment disputes or collection shortfalls, may be used to pay customers’ obligations to various third parties as directed by the customer, are periodically released to or withdrawn by customers, and are reported as deposits in the consolidated balance sheets. At September 30, 2021 and December 31, 2020 the balance of the Over-Formula Advance Portfolio included in factored receivables was $10,077,000 and $62,100,000, respectively. As of September 30, 2021 the Company carried a separate $19,361,000 receivable (the “Misdirected Payments”) payable by the United States Postal Service (“USPS”) arising from accounts factored to the largest Over-Formula Advance Portfolio carrier. This amount is separate from the acquired Over-Formula Advances. The amounts represented by this receivable were paid by the USPS directly to such customer in contravention of notices of assignment delivered to, and previously honored by, the USPS, which amount was then not remitted back to us by such customer as required. The USPS disputes their obligation to make such payment, citing purported deficiencies in the notices delivered to them. In addition to commencing litigation against such customer, we have commenced litigation against the USPS seeking a ruling that the USPS was obligated to make the payments represented by this receivable directly to us. During the third quarter of 2021 we, together with the USPS, entered into a stipulation of dismissal without prejudice for our initial action with respect to this matter in United States Federal District Court and filed a new action seeking recourse from the USPS in the United States Court of Federal Claims. Based on our legal analysis and discussions with our counsel advising us on this matter, we continue to believe it is probable that we will prevail in such action and that the USPS will have the capacity to make payment on such receivable. Consequently, the Company has not reserved for such balance as of September 30, 2021. Loans with carrying amounts of $1,652,900,000 and $2,255,441,000 at September 30, 2021 and December 31, 2020, respectively, were pledged to secure Federal Home Loan Bank borrowing capacity, Paycheck Protection Program Liquidity Facility borrowings and Federal Reserve Bank discount window borrowing capacity. During the three and nine months ended September 30, 2021, loans with carrying amounts of $12,373,000 and $76,976,000, respectively, were transferred from loans held for investment to loans held for sale at fair value concurrently with management’s change in intent and decision to sell the loans. During the three and nine months ended September 30, 2021, loans transferred to held for sale were sold resulting in proceeds of $17,446,000 and $63,028,000, respectively. The Company recorded net gains on transfers and sales of loans of $210,000 and $1,676,000, respectively, for the three and nine months ended September 30, 2021, which are recorded as other noninterest income in the consolidated statements of income. During the three and nine months ended September 30, 2020, loans with a carrying amount of $56,934,000 and $172,565,000, respectively, were transferred from loans held for investment to loans held for sale at fair value concurrently with management’s change in intent and decision to sell the loans. During the three and nine months ended September 30, 2020, loans transferred to held for sale were sold resulting in proceeds of $58,313,000 and $145,513,000, respectively. The Company recorded net losses on transfers and sales of loans of $515,000 and $466,000 for the three and nine months ended September 30, 2020. Allowance for Credit Losses The Company’s estimate of the ACL reflects losses expected over the remaining contractual life of the assets. The contractual term does not consider extensions, renewals or modifications unless the Company has identified an expected troubled debt restructuring. The activity in the allowance for credit losses (“ACL”) related to loans held for investment is as follows: (Dollars in thousands) Beginning Credit Loss Charge-offs Recoveries Ending Three months ended September 30, 2021 Commercial real estate $ 4,404 $ (453) $ (17) $ 2 $ 3,936 Construction, land development, land 1,490 (434) — 1 1,057 1-4 family residential 545 (64) (1) 5 485 Farmland 669 (59) — — 610 Commercial 15,674 (1,187) (211) — 14,276 Factored receivables 21,823 1,186 (3,597) 239 19,651 Consumer 236 153 (139) — 250 Mortgage warehouse 853 (101) — — 752 $ 45,694 $ (959) $ (3,965) $ 247 $ 41,017 (Dollars in thousands) Beginning Initial ACL on Loans Purchased with Credit Deterioration Credit Loss Charge-offs Recoveries Ending Three months ended September 30, 2020 Commercial real estate $ 15,539 $ — $ (2,440) $ — $ 53 $ 13,152 Construction, land development, land 5,917 — (319) — 2 5,600 1-4 family residential 2,027 — (56) (6) 7 1,972 Farmland 958 — (95) — — 863 Commercial 23,283 — (657) (528) 615 22,713 Factored receivables 5,244 37,415 3,059 (773) 40 44,985 Consumer 768 — 29 (118) 31 710 Mortgage warehouse 877 — 123 — — 1,000 $ 54,613 $ 37,415 $ (356) $ (1,425) $ 748 $ 90,995 (Dollars in thousands) Beginning Credit Loss Charge-offs Recoveries Ending Nine Months Ended September 30, 2021 Commercial real estate $ 10,182 $ (6,239) $ (17) $ 10 $ 3,936 Construction, land development, land 3,418 (2,352) (12) 3 1,057 1-4 family residential 1,225 (804) (26) 90 485 Farmland 832 (222) — — 610 Commercial 22,040 (7,936) (426) 598 14,276 Factored receivables 56,463 8,547 (45,683) 324 19,651 Consumer 542 (99) (285) 92 250 Mortgage warehouse 1,037 (285) — — 752 $ 95,739 $ (9,390) $ (46,449) $ 1,117 $ 41,017 (Dollars in thousands) Beginning Impact of Initial ACL on Loans Purchased with Credit Deterioration Credit Loss Charge-offs Recoveries Reclassification Ending Nine months ended September 30, 2020 Commercial real estate $ 5,353 $ 1,372 $ — $ 6,366 $ — $ 61 $ — $ 13,152 Construction, land development, land 1,382 (187) — 4,400 — 5 — 5,600 1-4 family residential 308 513 — 1,138 (27) 40 — 1,972 Farmland 670 437 — (324) — 80 — 863 Commercial 12,566 (184) — 11,004 (1,173) 949 (449) 22,713 Factored receivables 7,657 (1,630) 37,415 4,475 (3,027) 95 — 44,985 Consumer 488 (52) — 583 (410) 101 — 710 Mortgage warehouse 668 — — 332 — — — 1,000 $ 29,092 $ 269 $ 37,415 $ 27,974 $ (4,637) $ 1,331 $ (449) $ 90,995 The ACL was estimated using the current expected credit loss model. The primary reasons for the decrease in required ACL during the nine months ended September 30, 2021 are net charge-offs on PCD Over-Formula Advances (classified as factored receivables) and improvement of the loss drivers that the Company forecasts to calculate expected losses during the period. The primary reason for the decrease in required ACL during the three months ended September 30, 2021 is a decrease in specific reserves commensurate with a decrease in nonperforming loans. Management determined that the $62,200,000 in Over-Formula Advances obtained through the TFS Acquisition during 2020 had experienced more than insignificant credit deterioration since origination and thus deemed those Over-Formula Advances to be purchased credit deteriorated ("PCD"). The total remaining ACL on all acquired PCD Over-Formula Advances was approximately $10,077,000 at September 30, 2021 compared to $48,485,000 at December 31, 2020. The primary driver of the decrease in required ACL during the nine months ended September 30, 2021 was a net charge-off of $41,265,000 due from the largest acquired Over-Formula Advance client. This was partially offset by an additional $2,844,000 million of reserve required across the two remaining Over-Formula Advance clients. As of September 30, 2021, the entire remaining acquired PCD Over-Formula Advance balance was fully reserved. See Note 2 – Business Combinations and Divestitures for further discussion of Over-Formula Advance activity. The Company uses the discounted cash flow (DCF) method to estimate ACL for the commercial real estate, construction, land development, land, 1-4 family residential, commercial (excluding liquid credit), and consumer loan pools. For all loan pools utilizing the DCF method, the Company utilizes and forecasts national unemployment as a loss driver. The Company also utilizes and forecasts either one-year percentage change in national retail sales (commercial real estate – non multifamily, commercial general, commercial agriculture, commercial asset-based lending, commercial equipment finance, consumer), one-year percentage change in the national home price index (1-4 family residential and construction, land development, land), or one-year percentage change in national gross domestic product (commercial real estate – multifamily) as a second loss driver depending on the nature of the underlying loan pool and how well that loss driver correlates to expected future losses. Consistent forecasts of the loss drivers are used across the loan segments. For all DCF models at September 30, 2021, the Company has determined that four quarters represents a reasonable and supportable forecast period and reverts back to a historical loss rate over eight quarters on a straight-line basis. The Company leverages economic projections from a reputable and independent third party to inform its loss driver forecasts over the four-quarter forecast period. Other internal and external indicators of economic forecasts are also considered by the Company when developing the forecast metrics. At September 30, 2021, as compared to December 31, 2020, the Company forecasted a significant decrease in national unemployment, an increase in one-year percentage change in national retail sales, an increase in one-year percentage change in the national home price index, and an increase in one-year percentage change in national gross domestic product. At September 30, 2021, for percentage changes in national retail sales, national home price index and national gross domestic product, the Company projected significant growth in the first projected quarter followed by percentage change growth for the last three projected quarters resembling something closer to pre-COVID-19 levels albeit slightly more modest. Projected unemployment rates used by the Company are relatively stable over the four projected quarters at levels somewhat higher than pre-COVID-19 conditions. The Company uses a loss-rate method to estimate expected credit losses for the farmland, liquid credit, factored receivable, and mortgage warehouse loan pools. For each of these loan segments, the Company applies an expected loss ratio based on internal and peer historical losses adjusted as appropriate for qualitative factors. Qualitative loss factors are based on the Company's judgment of company, market, industry or business specific data, changes in underlying loan composition of specific portfolios, trends relating to credit quality, delinquency, non-performing and adversely rated loans, and reasonable and supportable forecasts of economic conditions. Loss factors used to calculate the required ACL on pools that use the loss-rate method reflect the forecasted economic conditions described above. For the nine months ended September 30, 2021, in addition to the impact of changes to the ACL on acquired PCD Over-Formula Advances previously discussed, changes in projected loss drivers and assumptions over the reasonable and supportable forecast period decreased the required ACL by $10,319,000. Further, the Company experienced a net reserve release of specific reserves on non-PCD loans. Changes in loan volume and mix during the nine months ended September 30, 2021 also decreased the ACL during the period. Non-PCD-related net charge-offs reduced the ACL by $4,067,000 during the nine months ended September 30, 2021. For the three months ended September 30, 2021, changes in projected loss drivers and assumptions over the reasonable and supportable forecast period decreased the required ACL by $177,000. Further, the Company experienced a net reserve release of specific reserves on non-PCD loans. Changes in loan volume and mix during the three months ended September 30, 2021 did not have a significant impact the ACL during the period. Non-PCD-related net charge-offs reduced the ACL by $3,718,000 during the three months ended September 30, 2021.

Aging of the Over-Formula Advances is based upon the service month on which the advances were made by TFS prior to acquisition. At September 30, 2021 and December 31, 2020, the Misdirected Payments totaled $19,361,000 and $19,600,000, respectively. At September 30, 2021, the entire $19,361,000 balance of the Misdirected Payments was considered past due 90 days or more, and at December 31, 2020 approximately $6,000,000 was considered past due 90 days or more. Given the nature of factored receivables, these assets are disclosed as past due 90 days or more still accruing; however, the Company is not recognizing income on the assets at September 30, 2021. Historically, any income recognized on factored receivables that are past due 90 days or more has not been material.

This amount is also considered Classified from a risk rating perspective. 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 – Pass rated loans have low to average risk and are not otherwise classified. Classified – Classified loans 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. Certain classified loans have 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. Management considers the guidance in ASC 310-20 when determining whether a modification, extension, or renewal of loan constitutes a current period origination. Generally, current period renewals of credit are re-underwritten at the point of renewal and considered current period originations for purposes of the table below. As of September 30, 2021 and December 31, 2020, based on the most recent analysis performed, the risk category of loans is as follows: Revolving Revolving Total (Dollars in thousands) Year of Origination September 30, 2021 2021 2020 2019 2018 2017 Prior Commercial real estate Pass $ 161,022 $ 254,852 $ 48,186 $ 33,865 $ 56,081 $ 46,685 $ 25,243 $ — $ 625,934 Classified 690 3,425 41 — 16 — — — 4,172 Total commercial real estate $ 161,712 $ 258,277 $ 48,227 $ 33,865 $ 56,097 $ 46,685 $ 25,243 $ — $ 630,106 Construction, land development, land Pass $ 76,239 $ 57,943 $ 12,580 $ 21,680 $ 1,214 $ 1,159 $ 9 $ — $ 170,824 Classified — 845 — — — 145 — — 990 Total construction, land development, land $ 76,239 $ 58,788 $ 12,580 $ 21,680 $ 1,214 $ 1,304 $ 9 $ — $ 171,814 1-4 family residential Pass $ 21,915 $ 18,191 $ 9,961 $ 7,170 $ 10,068 $ 25,998 $ 32,018 $ 327 $ 125,648 Classified 219 240 53 7 8 816 82 — 1,425 Total 1-4 family residential $ 22,134 $ 18,431 $ 10,014 $ 7,177 $ 10,076 $ 26,814 $ 32,100 $ 327 $ 127,073 Farmland Pass $ 11,922 $ 14,111 $ 11,021 $ 8,749 $ 10,212 $ 22,761 $ 1,283 $ 130 $ 80,189 Classified 699 524 650 336 128 307 157 — 2,801 Total farmland $ 12,621 $ 14,635 $ 11,671 $ 9,085 $ 10,340 $ 23,068 $ 1,440 $ 130 $ 82,990 Commercial Pass $ 419,788 $ 401,324 $ 92,389 $ 25,544 $ 17,534 $ 7,485 $ 413,973 $ 436 $ 1,378,473 Classified 1,422 7,995 5,493 571 66 464 4,013 — 20,024 Total commercial $ 421,210 $ 409,319 $ 97,882 $ 26,115 $ 17,600 $ 7,949 $ 417,986 $ 436 $ 1,398,497 Factored receivables Pass $ 1,575,756 $ — $ — $ — $ — $ — $ — $ — $ 1,575,756 Classified 10,594 20,678 — — — — — — 31,272 Total factored receivables $ 1,586,350 $ 20,678 $ — $ — $ — $ — $ — $ — $ 1,607,028 Consumer Pass $ 2,173 $ 2,072 $ 805 $ 689 $ 2,739 $ 3,881 $ 68 $ — $ 12,427 Classified 5 — — 1 123 121 — — 250 Total consumer $ 2,178 $ 2,072 $ 805 $ 690 $ 2,862 $ 4,002 $ 68 $ — $ 12,677 Mortgage warehouse Pass $ 752,545 $ — $ — $ — $ — $ — $ — $ — $ 752,545 Classified — — — — — — — — — Total mortgage warehouse $ 752,545 $ — $ — $ — $ — $ — $ — $ — $ 752,545 Total loans Pass $ 3,021,360 $ 748,493 $ 174,942 $ 97,697 $ 97,848 $ 107,969 $ 472,594 $ 893 $ 4,721,796 Classified 13,629 33,707 6,237 915 341 1,853 4,252 — 60,934 Total loans $ 3,034,989 $ 782,200 $ 181,179 $ 98,612 $ 98,189 $ 109,822 $ 476,846 $ 893 $ 4,782,730 Revolving Revolving Total (Dollars in thousands) Year of Origination December 31, 2020 2020 2019 2018 2017 2016 Prior Commercial real estate Pass $ 271,406 $ 94,085 $ 62,075 $ 49,115 $ 27,921 $ 230,731 $ 27,666 $ 908 $ 763,907 Classified 10,298 2,239 133 1,367 664 550 — — 15,251 Total commercial real estate $ 281,704 $ 96,324 $ 62,208 $ 50,482 $ 28,585 $ 231,281 $ 27,666 $ 908 $ 779,158 Construction, land development, land Pass $ 72,149 $ 12,490 $ 11,829 $ 5,820 $ 8,946 $ 105,584 $ 12 $ 500 $ 217,330 Classified 2,031 34 — — — 252 — — 2,317 Total construction, land development, land $ 74,180 $ 12,524 $ 11,829 $ 5,820 $ 8,946 $ 105,836 $ 12 $ 500 $ 219,647 1-4 family residential Pass $ 58,300 $ 11,280 $ 11,425 $ 8,982 $ 4,400 $ 20,167 $ 35,326 $ 5,320 $ 155,200 Classified 1,473 149 137 23 11 49 105 — 1,947 Total 1-4 family residential $ 59,773 $ 11,429 $ 11,562 $ 9,005 $ 4,411 $ 20,216 $ 35,431 $ 5,320 $ 157,147 Farmland Pass $ 37,212 $ 10,095 $ 7,388 $ 15,262 $ 7,908 $ 20,572 $ 1,421 $ 486 $ 100,344 Classified 994 407 403 — 22 590 925 — 3,341 Total farmland $ 38,206 $ 10,502 $ 7,791 $ 15,262 $ 7,930 $ 21,162 $ 2,346 $ 486 $ 103,685 Commercial Pass $ 470,477 $ 162,203 $ 127,569 $ 94,154 $ 70,405 $ 181,312 $ 416,197 $ 11,396 $ 1,533,713 Classified 8,128 2,390 983 190 4,470 2,787 10,296 — 29,244 Total commercial $ 478,605 $ 164,593 $ 128,552 $ 94,344 $ 74,875 $ 184,099 $ 426,493 $ 11,396 $ 1,562,957 Factored receivables Pass $ 1,081,316 $ — $ — $ — $ — $ — $ — $ — $ 1,081,316 Classified 39,454 — — — — — — — 39,454 Total factored receivables $ 1,120,770 $ — $ — $ — $ — $ — $ — $ — $ 1,120,770 Consumer Pass $ 8,382 $ 2,251 $ 1,336 $ 1,258 $ 688 $ 1,594 $ 74 $ — $ 15,583 Classified 146 28 18 36 11 16 — — 255 Total consumer $ 8,528 $ 2,279 $ 1,354 $ 1,294 $ 699 $ 1,610 $ 74 $ — $ 15,838 Mortgage warehouse Pass $ 1,037,574 $ — $ — $ — $ — $ — $ — $ — $ 1,037,574 Classified — — — — — — — — — Total mortgage warehouse $ 1,037,574 $ — $ — $ — $ — $ — $ — $ — $ 1,037,574 Total loans Pass $ 3,036,816 $ 292,404 $ 221,622 $ 174,591 $ 120,268 $ 559,960 $ 480,696 $ 18,610 $ 4,904,967 Classified 62,524 5,247 1,674 1,616 5,178 4,244 11,326 — 91,809 Total loans $ 3,099,340 $ 297,651 $ 223,296 $ 176,207 $ 125,446 $ 564,204 $ 492,022 $ 18,610 $ 4,996,776 Troubled Debt Restructurings and Loan Modifications The Company had troubled debt restructurings with an amortized cost of $5,065,000 and $13,324,000 as of September 30, 2021 and December 31, 2020, respectively.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	DERIVATIVE FINANCIAL INSTRUMENTS The Company is exposed to certain risk arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk primarily by managing the amount, sources, and duration of its assets and liabilities and the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company’s derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally related to the Company’s interest bearing deposits. The Company’s objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. Beginning in June 2020, such derivatives were used to hedge the variable cash flows associated with interest bearing deposits. For derivatives designated and that qualify as cash flow hedges of interest rate risk, the gain or loss on the derivative is recorded in Accumulated Other Comprehensive Income and subsequently reclassified into interest expense in the same period(s) during which the hedged transaction affects earnings. Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense as interest payments are made on the Company’s variable-rate interest bearing deposits. During 2021, the Company estimates that an additional $58,000 will be reclassified as an increase in interest expense.

The Company has agreements with certain of its derivative counterparties that contain a provision where if the company fails to maintain its status as a well capitalized institution, then the Company could be required to post additional collateral. As of September 30, 2021, the fair value of derivatives in a net liability position, which includes accrued interest, related to these agreements was $0. As of September 30, 2021, the Company has not posted any collateral related to these agreements. If the Company had breached any of these provisions at September 30, 2021, it could have been required to settle its obligations under the agreements at their termination value of $3,940,000.

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.

Commitments and Contingencies Disclosure [Abstract]
Off-Balance Sheet Loan Commitments	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: September 30, 2021 December 31, 2020 (Dollars in thousands) Fixed Rate Variable Rate Total Fixed Rate Variable Rate Total Unused lines of credit $ 25,574 $ 381,584 $ 407,158 $ 43,406 $ 547,430 $ 590,836 Standby letters of credit $ 7,819 $ 5,782 $ 13,601 $ 5,464 $ 8,429 $ 13,893 Commitments to purchase loans $ — $ 88,620 $ 88,620 $ — $ 66,373 $ 66,373 Mortgage warehouse commitments $ — $ 844,903 $ 844,903 $ — $ 417,722 $ 417,722 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. Commitments to purchase loans represent loans purchased by the Company that have not yet settled. 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 records an allowance for credit losses on off-balance sheet credit exposures through a charge to credit loss expense on the Company’s consolidated statements of income. At September 30, 2021 and December 31, 2020, the allowance for credit losses on off-balance sheet credit exposures totaled $3,846,000 and $5,005,000, respectively, and was included in other liabilities on the Company’s consolidated balance sheets.

Fair Value Disclosures [Abstract]
Fair Value Disclosures	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 the methodologies disclosed in Note 17 of the Company’s 2020 Form 10-K. Assets and liabilities measured at fair value on a recurring basis are summarized in the table below. (Dollars in thousands) Fair Value Measurements Using Total September 30, 2021 Level 1 Level 2 Level 3 Assets measured at fair value on a recurring basis Securities available for sale U.S. Government agency obligations $ — $ 5,001 $ — $ 5,001 Mortgage-backed securities, residential — 18,167 — 18,167 Asset-backed securities — 6,864 — 6,864 State and municipal — 29,175 — 29,175 CLO securities — 100,719 — 100,719 Corporate bonds — 2,061 — 2,061 SBA pooled securities — 2,829 — 2,829 $ — $ 164,816 $ — $ 164,816 Equity securities Mutual fund $ 5,623 $ — $ — $ 5,623 Loans held for sale $ — $ 26,437 $ — $ 26,437 Derivative financial instruments (cash flow hedges) Interest rate swap $ — $ 3,948 $ — $ 3,948 Indemnification asset $ — $ — $ 4,786 $ 4,786 (Dollars in thousands) Fair Value Measurements Using Total December 31, 2020 Level 1 Level 2 Level 3 Assets measured at fair value on a recurring basis Securities available for sale U.S. Government agency obligations $ — $ 15,088 $ — $ 15,088 Mortgage-backed securities, residential — 27,684 — 27,684 Asset-backed securities — 7,039 — 7,039 State and municipal — 37,395 — 37,395 CLO Securities — 122,204 — 122,204 Corporate bonds — 11,573 — 11,573 SBA pooled securities — 3,327 — 3,327 $ — $ 224,310 $ — $ 224,310 Equity securities Mutual fund $ 5,826 $ — $ — $ 5,826 Loans held for sale $ — $ 24,546 $ — $ 24,546 Derivative financial instruments (cash flow hedges) Interest rate swap $ — $ 816 $ — $ 816 Indemnification asset $ — $ — $ 36,225 $ 36,225 There were no transfers between levels during 2021 or 2020. The fair value of the indemnification asset is calculated as the present value of the estimated cash payments expected to be received from Covenant for probable losses on the covered Over-Formula Advance Portfolio. The cash flows are discounted at a rate to reflect the uncertainty of the timing and receipt of the payments from Covenant. The indemnification asset is reviewed quarterly and changes to the asset are recorded as adjustments to other noninterest income or expense, as appropriate, within the Consolidated Statements of Income. The indemnification asset fair value is considered a Level 3 classification. At September 30, 2021 and December 31, 2020, the estimated cash payments expected to be received from Covenant for probable losses on the covered Over-Formula Advance Portfolio were approximately $5,038,000 and $39,200,000, respectively, and a discount rate of 5.0% and 8.8%, respectively, was applied to calculate the present value of the indemnification asset. A reconciliation of the opening balance to the closing balance of the fair value of the indemnification asset is as follows: Three Months Ended September 30, Nine Months Ended September 30, (Dollars in thousands) 2021 2020 2021 2020 Beginning balance $ 5,246 $ — $ 36,225 $ — Indemnification asset recognized in business combination — 30,959 — 30,959 Change in fair value of indemnification asset recognized in earnings (460) — 4,194 — Indemnification recognized — — (35,633) — Ending balance $ 4,786 $ 30,959 $ 4,786 $ 30,959 Assets measured at fair value on a non-recurring basis are summarized in the table below.

Collateral Dependent Loans Specific Allocation of ACL : A loan is considered to be a collateral dependent loan when, based on current information and events, the Company expects repayment of the financial assets to be provided substantially through the operation or sale of the collateral and the Company has determined that the borrower is experiencing financial difficulty as of the measurement date. The ACL is measured by estimating the fair value of the loan based on the present value of expected cash flows, the market price of the loan, or the underlying fair value of the loan’s collateral. For real estate loans, fair value of the loan’s collateral is determined by third party appraisals, which are then adjusted for the estimated selling and closing costs related to liquidation of the collateral. For this asset class, the actual valuation methods (income, sales comparable, or cost) vary based on the status of the project or property. For example, land is generally based on the sales comparable method while construction is based on the income and/or sales comparable methods. The unobservable inputs may vary depending on the individual assets with no one of the three methods being the predominant approach. The Company reviews the third party appraisal for appropriateness and adjusts the value downward to consider selling and closing costs, which typically range from 5% to 8% of the appraised value. For non-real estate loans, fair value of the loan’s collateral may be determined using an appraisal, net book value per the borrower’s financial statements, or aging reports, adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of the valuation, and management’s expertise and knowledge of the client and client’s business. OREO : OREO is primarily comprised of real estate acquired in partial or full satisfaction of loans. OREO is recorded at its estimated fair value less estimated selling and closing costs at the date of transfer, with any excess of the related loan balance over the fair value less expected selling costs charged to the ACL. Subsequent changes in fair value are reported as adjustments to the carrying amount and are recorded against earnings. The Company outsources the valuation of OREO with material balances to third party appraisers. For this asset class, the actual valuation methods (income, sales comparable, or cost) vary based on the status of the project or property. For example, land is generally based on the sales comparable method while construction is based on the income and/or sales comparable methods. The unobservable inputs may vary depending on the individual assets with no one of the three methods being the predominant approach. The Company reviews the third party appraisal for appropriateness and adjusts the value downward to consider selling and closing costs, which typically range from 5% to 8% of the appraised value. The estimated fair values of the Company’s financial instruments not measured at fair value on a recurring or non-recurring basis at September 30, 2021 and December 31, 2020 were as follows: (Dollars in thousands) Carrying Fair Value Measurements Using Total September 30, 2021 Level 1 Level 2 Level 3 Financial assets: Cash and cash equivalents $ 532,764 $ 532,764 $ — $ — $ 532,764 Securities - held to maturity 5,488 — — 5,534 5,534 Loans not previously presented, gross 4,747,031 142,996 — 4,611,706 4,754,702 FHLB and other restricted stock 4,901 N/A N/A N/A N/A Accrued interest receivable 16,031 16,031 — — 16,031 Financial liabilities: Deposits 4,822,575 — 4,823,597 — 4,823,597 Customer repurchase agreements 11,990 — 11,990 — 11,990 Federal Home Loan Bank advances 30,000 — 30,000 — 30,000 Paycheck Protection Program Liquidity Facility 97,554 — 97,554 — 97,554 Subordinated notes 106,755 — 107,536 — 107,536 Junior subordinated debentures 40,467 — 41,085 — 41,085 Accrued interest payable 1,976 1,976 — — 1,976 (Dollars in thousands) Carrying Fair Value Measurements Using Total December 31, 2020 Level 1 Level 2 Level 3 Financial assets: Cash and cash equivalents $ 314,393 $ 314,393 $ — $ — $ 314,393 Securities - held to maturity 5,919 — — 5,850 5,850 Loans not previously presented, gross 4,953,399 195,739 — 4,783,143 4,978,882 FHLB and other restricted stock 6,751 N/A N/A N/A N/A Accrued interest receivable 19,435 19,435 — — 19,435 Financial liabilities: Deposits 4,716,600 — 4,719,625 — 4,719,625 Customer repurchase agreements 3,099 — 3,099 — 3,099 Federal Home Loan Bank advances 105,000 — 105,000 — 105,000 Paycheck Protection Program Liquidity Facility 191,860 — 191,860 — 191,860 Subordinated notes 87,509 — 89,413 — 89,413 Junior subordinated debentures 40,072 — 40,379 — 40,379 Accrued interest payable 4,270 4,270 — — 4,270

Regulatory Matters

Broker-Dealer, Net Capital Requirement, SEC Regulation [Abstract]
Regulatory Matters	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 September 30, 2021 and December 31, 2020, the Company and TBK Bank meet all capital adequacy requirements to which they are subject. As of September 30, 2021 and December 31, 2020, 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 September 30, 2021 that management believes have changed TBK Bank’s category. The actual capital amounts and ratios for the Company and TBK Bank are presented in the following table.

The initial impact of adoption of ASU 2016-13 as well as 25% of the quarterly increases in the allowance for credit losses subsequent to adoption of ASU 2016-13 (collectively the “transition adjustments”) will be delayed for two years. After two years, the cumulative amount of the transition adjustments will become fixed and will be phased out of the regulatory capital calculations evenly over a three year period, with 75% recognized in year three, 50% recognized in year four, and 25% recognized in year five. After five years, the temporary regulatory capital benefits will be fully reversed. Dividends paid by TBK Bank are limited to, without prior regulatory approval, current year earnings and earnings less dividends paid during the preceding two years.

The cost is expected to be recognized over a remaining period of 2.06 years. Performance Based Performance Stock Units A summary of changes in the Company’s nonvested Performance Based Performance Stock Units (“Performance Based PSUs”) under the Omnibus Incentive Plan for the nine months ended September 30, 2021 were as follows: Nonvested Performance Based PSUs Shares Weighted Average Nonvested at January 1, 2021 256,625 $ 37.56 Granted 9,000 88.63 Vested — — Forfeited (6,242) 38.02 Nonvested at September 30, 2021 259,383 $ 39.32 Performance Based PSUs granted to employees under the Omnibus Incentive Plan vest after three years. The number of shares issued upon vesting will range from 0% to 200% of the shares granted based on the Company’s cumulative diluted earnings per share over the performance period. Compensation expense for the Performance Based PSUs will be estimated each period based on the fair value of the stock at the grant date and the most probable outcome of the performance condition, adjusted for the passage of time within the vesting period of the awards. As of September 30, 2021, the maximum unrecognized compensation cost related to the nonvested Performance Based PSUs was $20,396,000, and the remaining performance period over which the cost could be recognized was 1.25 years. No compensation cost was recorded during the three and nine months ended September 30, 2021 and 2020.

The fair value of stock options granted is estimated at the date of grant using the Black-Scholes option-pricing model. Expected volatilities were 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 the options granted was 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 the options was derived from the Treasury constant maturity yield curve on the valuation date. The fair value of the stock options granted was determined using the following weighted-average assumptions: Nine Months Ended September 30, 2021 2020 Risk-free interest rate 1.16 % 0.46 % Expected term 6.25 years 6.25 years Expected stock price volatility 39.26 % 33.83 % Dividend yield — — As of September 30, 2021, there was $512,000 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 2.94 years.

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”), TBK Bank’s wholly owned subsidiary Triumph Insurance Group, Inc. (“TIG”). TriumphPay operates as a division of TBK Bank, SSB.
Basis of Presentation	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 (“SEC”). 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, 2020. Operating results for the three and nine months ended September 30, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021.
Risks and Uncertainties	Risks and Uncertainties Significant progress has been made to combat the outbreak of COVID-19; however, the global pandemic has adversely impacted a broad range of industries in which the Company's customers operate and could still impair their ability to fulfill their financial obligations to the Company. The Company’s business is dependent upon the willingness and ability of its employees and customers to conduct banking and other financial transactions. While it appears that the epidemiological and macroeconomic conditions are trending in a positive direction as of September 30, 2021, if there is a resurgence in the virus, the Company could experience further adverse effects on its business, financial condition, results of operations and cash flows. While it is not possible to know the full universe or extent that the impact of COVID-19, and any potential resulting measures to curtail its spread, will have on the Company's future operations, the Company is disclosing potentially material items of which it is aware. Financial position and results of operations The Company’s interest income could be reduced due to COVID-19. In keeping with guidance from regulators, the Company continues to work with COVID-19 affected borrowers to defer their payments, interest, and fees. While interest and fees continue to accrue to income through normal GAAP accounting, should eventual credit losses on these deferred payments emerge, the related loans would be placed on nonaccrual status and interest income and fees accrued would be reversed. In such a scenario, interest income in future periods could be negatively impacted. As of September 30, 2021 the Company carries $121,000 of accrued interest income and fees on outstanding deferrals made to COVID-19 affected borrowers. At this time, the Company is unable to project the materiality of such an impact on future deferrals to COVID-19 affected borrowers, but recognizes the breadth of the economic impact may affect its borrowers’ ability to repay in future periods. Capital and liquidity The Company's reported and regulatory capital ratios could be adversely impacted by further credit loss expense. The Company relies on cash on hand as well as dividends from its subsidiary bank to service its debt. If the Company's capital deteriorates such that its subsidiary bank is unable to pay dividends to the Company for an extended period of time, the Company may not be able to service its debt. The Company maintains access to multiple sources of liquidity. Wholesale funding markets have remained open to the Company, but rates for short-term funding can be volatile. If funding costs are elevated for an extended period of time, it could have an adverse effect on the Company's net interest margin. If an extended recession caused large numbers of the Company's deposit customers to withdraw their funds, the Company might become more reliant on volatile or more expensive sources of funding. Intangible asset valuation The lingering effects COVID-19 could cause a decline in the Company’s stock price or the occurrence of what management would deem to be a triggering event that could, under certain circumstances, cause us to perform a goodwill impairment test and result in an impairment charge being recorded for that period. In the event that the Company concludes that all or a portion of its goodwill is impaired, a non-cash charge for the amount of such impairment would be recorded to earnings. Such a charge would have no impact on tangible capital or regulatory capital. It is possible that the lingering effects of COVID-19 could cause the occurrence of what management would deem to be a triggering event that could, under certain circumstances, cause us to perform an intangible asset impairment test and result in an impairment charge being recorded for that period. In the event that the Company concludes that all or a portion of its intangible assets are impaired, a non-cash charge for the amount of such impairment would be recorded to earnings. Such a charge would have no impact on tangible capital or regulatory capital. Lending operations and accommodations to borrowers In keeping with regulatory guidance to work with borrowers during this unprecedented situation and as outlined in the Section 4013 of the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) , the Company is executing a payment deferral program for its commercial lending clients that are adversely affected by the pandemic. Depending on the demonstrated need of the client, the Company is deferring either the full loan payment or the principal component of the loan payment for a stated period of time. As of September 30, 2021, the Company’s balance sheet reflected 3 of these deferrals on outstanding loan balances of $32,220,000. In accordance with the CARES Act and March 2020 interagency guidance, these deferrals are not considered troubled debt restructurings. It is possible that these deferrals could be extended further under the CARES Act; however, the volume of these future potential extensions is unknown. It is also possible that in spite of the Company's best efforts to assist its borrowers and achieve full collection of the Company's investment, these deferred loans could result in future charge-offs with additional credit loss expense charged to earnings; however, the amount of any future charge-offs on deferred loans is unknown. At September 30, 2021, 94% of the $32,220,000 COVID deferral balance was made up of one relationship. With the passage of the Paycheck Protection Program (“PPP”), administered by the Small Business Administration (“SBA”), the Company has participated in assisting its customers with applications for resources through the program. PPP loans have two-year and five-year terms and earn interest at a 1% coupon. The Company believes that the majority of these loans will ultimately be forgiven by the SBA in accordance with the terms of the program. As of September 30, 2021, the Company carried 815 PPP loans representing a book value of $87,413,000. The Company recognized $1,584,000 and $4,524,000 in fees from the SBA on PPP loans during the three and nine months ended September 30, 2021 and carried $3,580,000 of deferred fees on PPP loans at September 30, 2021. The remaining fees will be amortized and recognized over the remaining lives of the loans. It is the Company’s understanding that loans funded through the PPP program are fully guaranteed by the U.S. government. Should those circumstances change, the Company could be required to establish an allowance for credit loss through additional credit loss expense charged to earnings. Credit The Company is working with customers directly affected by COVID-19. The Company is prepared to offer assistance in accordance with regulator guidelines. As a result of the current economic environment caused by the COVID-19 virus, the Company is engaging in communication with borrowers to understand their situation and the challenges faced, allowing the Company to respond proactively as needs and issues arise. Should the economy experience a prolonged period of poor economic conditions or should economic conditions worsen, the Company could experience increases in its required allowance for credit losses (“ACL”) and record additional credit loss expense. It is possible that the Company’s asset quality measures could worsen at future measurement periods if the effects of COVID-19 are prolonged.
