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.

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, 2018. Operating results for the three months ended March 31, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019.

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.

Premises and Equipment

The Company leases certain properties and equipment under operating leases. For leases in effect upon adoption of Accounting Standards Update 2016-02, “Leases (Topic 842)” at January 1, 2019 and for any leases commencing thereafter, the Company recognizes a liability to make lease payments, the “lease liability”, and an asset representing the right to use the underlying asset during the lease term, the “right-of-use asset”. The lease liability is measured at the present value of the remaining lease payments, discounted at the Company’s incremental borrowing rate. The right-of-use asset is measured at the amount of the lease liability adjusted for the remaining balance of any lease incentives received, any cumulative prepaid or accrued rent if the lease payments are uneven throughout the lease term, any unamortized initial direct costs, and any impairment of the right-of-use-asset. Operating lease expense consists of a single lease cost calculated so that the remaining cost of the lease is allocated over the remaining lease term on a straight-line basis, variable lease payments not included in the lease liability, and any impairment of the right-of-use asset.

Certain of the Company’s leases contain options to renew the lease; however, these renewal options are not included in the calculation of the lease liabilities as they are not reasonably certain to be exercised. The Company’s leases do not contain residual value guarantees or material variable lease payments. The Company does not have any material restrictions or covenants imposed by leases that would impact the Company’s ability to pay dividends or cause the Company to incur additional financial obligations.

The Company has made an accounting policy election to not apply the recognition requirements in Topic 842 to short-term leases. The Company has also elected to use the practical expedient to make an accounting policy election for property leases to include both lease and nonlease components as a single component and account for it as a lease.

The Company’s leases are not complex; therefore there were no significant assumptions or judgements made in applying the requirements of Topic 842, including the determination of whether the contracts contained a lease, the allocation of consideration in the contracts between lease and nonlease components, and the determination of the discount rates for the leases.

Adoption of New Accounting Standards

In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“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 new standard was adopted by the Company on January 1, 2019. ASU 2016-02 provides for a modified retrospective transition approach requiring lessees to recognize and measure leases on the balance sheet at the beginning of either the earliest period presented or as of the beginning of the period of adoption. The Company elected to apply ASU 2016-02 as of the beginning of the period of adoption (January 1, 2019) and will not restate comparative periods. Adoption of ASU 2016-02 resulted in the recognition of lease liabilities totaling $21,918,000 and the recognition of right-of-use assets totaling $22,123,000 as of the date of adoption. Lease liabilities and right-of-use assets are reflected in other liabilities and other assets, respectively. The initial balance sheet gross up upon adoption was primarily related to operating leases of certain real estate properties. The Company has no finance leases or material subleases or leasing arrangements for which it is the lessor of property or equipment. The Company has elected to apply the package of practical expedients allowed by the new standard under which the Company need not reassess whether any expired or existing contracts are leases or contain leases, the Company need not reassess the lease classification for any expired or existing lease, and the Company need not reassess initial direct costs for any existing leases. Adoption of ASU 2016-02 is not expected to materially change the Company’s recognition of lease expense in future periods. See Note 5 – Premises and Equipment for additional disclosures related to leases.

Newly Issued, But Not Yet Effective Accounting Standards

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”). ASU 2016-13 makes significant changes to the accounting for credit losses on financial instruments and disclosures about them. The new current expected credit loss (CECL) impairment model will require an estimate of expected credit losses, measured over the contractual life of an instrument, which considers reasonable and supportable forecasts of future economic conditions in addition to information about past events and current conditions. The standard provides significant flexibility and requires a high degree of judgment with regards to pooling financial assets with similar risk characteristics, determining the contractual terms of said financial assets and adjusting the relevant historical loss information in order to develop an estimate of expected lifetime 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. The Company will adopt ASU 2016-13 on January 1, 2020. 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. ASU 2016-13 permits the use of estimation techniques that are practical and relevant to the Company’s circumstances, as long as they are applied consistently over time and faithfully estimate expected credit losses in accordance with the standard. The ASU lists several common credit loss methods that are acceptable such as a discounted cash flow (DCF) method, loss-rate method and roll-rate method. Depending on the nature of each identified pool of financial assets with similar risk characteristics, the Company currently plans on implementing a DCF method or a loss-rate method to estimate expected credit losses. The Company expects ASU 2016-13 to have a significant impact on the Company’s accounting policies, internal controls over financial reporting and footnote disclosures. The Company has assessed its data and system needs and has begun designing its financial models to estimate expected credit losses in accordance with the standard. Further development, testing and evaluation of said models is required to determine the impact that adoption of this standard will have on the financial condition and results of operations of the Company.

NOTE 2 – Business combinations AND DIVESTITURES

First Bancorp of Durango, Inc. and Southern Colorado Corp.

Effective September 8, 2018 the Company acquired (i) First Bancorp of Durango, Inc. (“FBD”) and its community banking subsidiaries, The First National Bank of Durango and Bank of New Mexico and (ii) Southern Colorado Corp. (“SCC”) and its community banking subsidiary, Citizens Bank of Pagosa Springs, in all-cash transactions. The acquisitions expanded the Company’s market in Colorado and into New Mexico and further diversified the Company’s loan, customer, and deposit base.

A summary of the estimate fair values of assets acquired, liabilities assumed, consideration transferred, and the resulting goodwill is as follows:

(Dollars in thousands)	FBD		SCC		Total
Assets acquired:
Cash and cash equivalents	$	151,973	$	14,299	$	166,272

Cash consideration transferred		134,667		13,294		147,961
Goodwill	$	68,009	$	4,066	$	72,075

The Company has recognized goodwill of $72,075,000, 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 these acquisitions resulted from expected synergies and expansion in the Colorado market and into the New Mexico market. The goodwill will be deducted for tax purposes. The intangible assets recognized in the transactions will be amortized utilizing an accelerated method over their ten year estimated useful lives. The initial accounting for the acquisitions has not been completed because the fair values of the assets acquired and liabilities assumed have not yet been finalized.

In connection with the acquisitions, 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 Loans						PCI Loans						Total Loans

Revenue and earnings of FBD and SCC since the acquisition date have not been disclosed as the acquired companies were merged into the Company and separate financial information is not readily available.

Expenses related to the acquisitions, including professional fees and other transaction costs, totaling $5,871,000 were recorded in noninterest expense in the consolidated statements of income during the three months ended September 30, 2018.

Interstate Capital Corporation

A summary of the estimated fair values of assets acquired, liabilities assumed, consideration transferred, and the resulting goodwill is as follows:

Total consideration		180,258
Goodwill	$	42,975

ICC’s net assets acquired were allocated to the Company’s Factoring segment whose factoring operations were significantly expanded as a result of the transaction. The Company has recognized goodwill of $42,975,000, which was calculated as the excess of both the fair value of cash consideration exchanged and the fair value of the contingent liability assumed 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 be deducted for tax purposes. The intangible assets recognized include a customer relationship intangible asset with an acquisition date fair value of $13,500,000 which will be amortized utilizing an accelerated method over its eight year estimated useful life and a trade name intangible asset with an acquisition date fair value of $420,000 which will be amortized on a straight-line basis over its three year estimated useful life.

Consideration paid included contingent consideration with an acquisition date fair value of $20,000,000. The contingent consideration is based on a proprietary index designed to approximate the rise and fall of transportation invoice prices subsequent to acquisition and is correlated to monthly movements in average invoice prices historically experienced by ICC. At the end of a 30 month earnout period, a final average index price will be calculated and the contingent consideration will be settled in cash based on the final average index price. Final contingent consideration payout will range from $0 to $22,000,000, and the fair value of the associated liability will be remeasured each reporting period with changes in fair value recorded in noninterest income in the consolidated statements of income. The fair value of the contingent consideration was $21,006,000 at March 31, 2019.

Revenue and earnings of ICC 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. 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.

Expenses related to the acquisition, including professional fees and other transaction costs, totaling $1,094,000 were recorded in noninterest expense in the consolidated statements of income during the three months ended June 30, 2018.

Management evaluates debt securities for other than temporary impairment at least on a quarterly basis, and more frequently when economic or market concerns warrant such evaluation. 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, 2019, the Company had 144 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, 2019, 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.

The difference between the recorded investment and the unpaid principal is primarily (1) premiums and discounts associated with acquisition date fair value adjustments on acquired loans (both PCI and non-PCI) totaling $17,861,000 and $19,514,000 at March 31, 2019 and December 31, 2018, respectively, and (2) net deferred origination and factoring fees totaling $2,710,000 and $2,579,000 at March 31, 2019 and December 31, 2018, respectively.

At March 31, 2019 and December 31, 2018, the Company had $54,295,000 and $58,566,000, 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.

Loans with carrying amounts of $971,582,000 and $847,523,000 at March 31, 2019 and December 31, 2018, respectively, were pledged to secure Federal Home Loan Bank borrowing capacity.

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.

PCI – At acquisition, PCI loans had the characteristics of classified 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.

As of March 31, 2019 and December 31, 2018, based on the most recent analysis performed, the risk category of loans is as follows:

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 $8,499,000 and $8,487,000 at March 31, 2019 and December 31, 2018, respectively, and are classified as held to maturity securities within the Company’s consolidated balance sheets.

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.

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, 2019						December 31, 2018
(Dollars in thousands)	Fixed Rate		Variable Rate		Total		Fixed Rate		Variable Rate		Total
Unused lines of credit	$	207,197	$	318,911	$	526,108	$	69,053	$	433,667	$	502,720
Standby letters of credit		1,807		4,063		5,870		2,285		3,931		6,216
Mortgage warehouse commitments		—		306,508		306,508		—		266,458		266,458

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 records 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, 2019 and December 31, 2018, the allowance for loan and lease losses on off-balance sheet lending-related commitments totaled $537,000 and $538,000, 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 $2,776,000 and $3,087,000 at March 31, 2019 and December 31, 2018, respectively.

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 the methodologies disclosed in Note 15 of the Company’s 2018 Form 10-K.

Assets and liabilities measured at fair value on a recurring basis are summarized in the table below.

There were no transfers between levels during 2019 or 2018.

On June 2, 2018, the Company acquired substantially all of the operating assets of, and assumed certain liabilities associated with, Interstate Capital Corporation’s (“ICC”) accounts receivable factoring business and other related financial services. Consideration for the acquisition included contingent consideration, which is based on a proprietary index designed to approximate the rise and fall of transportation invoice prices subsequent to acquisition. The index is calculated by a third party data analytics firm and is correlated to monthly movements in average invoice prices historically experienced by ICC. At the end of a 30 month earnout period after closing, a final average index price will be calculated and the contingent consideration will be settled in cash based on the final average index price, with a payout ranging from $0 to $22,000,000. The fair value of the contingent consideration is calculated each reporting period, and changes in the fair value of the contingent consideration are recorded in noninterest income in the consolidated statements of income. At March 31, 2019 and December 31, 2018, the ICC contingent consideration liability was the only recurring fair value measurement with Level 3 unobservable inputs. At March 31, 2019 and December 31, 2018, the fair value calculation of the contingent consideration resulted in a payout of $22,000,000, and discount rates of 2.6% and 2.9%, respectively, were applied to calculate the present value of the contingent consideration. A reconciliation of the opening balance to the closing balance of the fair value of the contingent consideration is as follows:

Impaired Loans with Specific Allocation of ALLL: A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due pursuant to the contractual terms of the loan agreement. Impairment 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 impaired 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 impaired 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 ALLL. 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 March 31, 2019 and December 31, 2018 were as follows:

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, 2019 and December 31, 2018, the Company and TBK Bank meet all capital adequacy requirements to which they are subject.

As of March 31, 2019 and December 31, 2018, 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, 2019 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.

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.

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 reached 2.5% on January 1, 2019. The capital conservation buffer was 2.5% and 1.875% at March 31, 2019 and December 31, 2018, 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, 2019 and December 31, 2018, the Company’s and TBK Bank’s risk based capital exceeded the required capital conservation buffer.

- Definition

The entire disclosure for banks, savings institutions, and credit unions, for regulatory capital requirements imposed by the Federal Reserve System (FRB), the Federal Deposit Insurance Corporation (FDIC), the Office of Thrift Supervision (OTS) or for any state imposed capital requirements, as applicable. The disclosure may include (1) a description of regulatory capital requirements (a) for capital adequacy purposes and (b) established by the prompt corrective action provisions of Section 38 of the Federal Depository Insurance Act; (2) the actual or possible material effects of noncompliance with such requirements; (3) whether the entity is in compliance with the regulatory capital requirements including (a) required and actual ratios and amounts of Tier 1 leverage, Tier 1 risk-based, and total risk-based capital, tangible capital (for savings institutions), and Tier 3 capital for market risk (for certain banks and bank holding companies), (b) factors that may significantly affect capital adequacy; (4) the prompt corrective action category in which the entity was classified as of its most recent notification; (5) whether management believes any conditions or events since notification have changed the entity's category. Also may include additional information that might be disclosed in situations where substantial doubt about the entity's ability to continue as a going concern for a reasonable period of time.

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, 2019 were as follows:

				Weighted-Average
				Grant-Date
Nonvested RSAs	Shares			Fair Value

Forfeited		(1,276	)		30.65
Nonvested at March 31, 2019		100,972		$	31.50

RSAs granted to employees under the Omnibus Incentive Plan typically vest over three to four years, but vesting periods may vary. Compensation expense for RSAs will be recognized over the vesting period of the awards based on the fair value of the stock at the issue date. At March 31, 2019, there was $1,417,000 of unrecognized compensation cost related to nonvested RSAs. The cost is expected to be recognized over a remaining weighted average period of 2.69 years.

Forfeited		(1,258	)		38.75
Nonvested at March 31, 2019		58,400		$	38.75

RSUs granted to employees under the Omnibus Incentive Plan vest after five years. Compensation expense for the RSUs will be recognized over the vesting period of the awards based on the fair value of the stock at the issue date. At March 31, 2019, there was $1,848,000 of unrecognized compensation cost related to the nonvested RSUs. The cost is expected to be recognized over a remaining period of 4.09 years.

Performance Stock Units

A summary of changes in the Company’s nonvested Performance Stock Units (“PSUs”) under the Omnibus Incentive Plan for the three months ended March 31, 2019 were as follows:

				Weighted Average
				Grant Date
Nonvested PSUs	Shares			Fair Value
Nonvested at January 1, 2019		59,658		$	38.57

Vested		—			—
Forfeited		(1,258	)		38.57
Nonvested at March 31, 2019		58,400		$	38.57

PSUs granted to employees under the Omnibus Incentive Plan vest after five years. The number of shares issued upon vesting will range from 0% to 175% of the PSUs granted based on the Company’s relative total shareholder return (“TSR”) as compared to the TSR of a specified group of peer banks. Compensation expense for the PSUs will be recognized over the vesting period of the awards based on the fair value of the award at the grant date. The fair value of PSUs granted is estimated using a Monte Carlo simulation. Expected volatilities are determined based on the historical volatilities of the Company and the specified peer group. The risk-free interest rate for the performance period is derived from the Treasury constant maturities yield curve on the valuation date.

At March 31, 2019, there was $1,839,000 of unrecognized compensation cost related to the nonvested PSUs. The cost is expected to be recognized over a remaining period of 4.09 years.

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.

At March 31, 2019, there was $496,000 of unrecognized compensation cost related to nonvested stock options. The cost is expected to be recognized over a remaining weighted average period of 2.68 years.

Business Segment Information

NOTE 15 – BUSINESS SEGMENT INFORMATION

The following table presents the Company’s operating segments. The accounting policies of the segments are the same as those described in the “Summary of Significant Accounting Policies” in Note 1 of the Company’s 2018 Form 10-K. Transactions between segments consist primarily of borrowed funds. Beginning in 2019, intersegment interest expense is allocated to the Factoring segment based on Federal Home Loan Bank advance rates. Prior to 2019, intersegment interest was calculated 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.

Summary of Significant Accounting Policies (Policies)	Mar. 31, 2019
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.
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, 2018. Operating results for the three months ended March 31, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019. 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.
Premises and Equipment	Premises and Equipment The Company leases certain properties and equipment under operating leases. For leases in effect upon adoption of Accounting Standards Update 2016-02, “Leases (Topic 842)” at January 1, 2019 and for any leases commencing thereafter, the Company recognizes a liability to make lease payments, the “lease liability”, and an asset representing the right to use the underlying asset during the lease term, the “right-of-use asset”. The lease liability is measured at the present value of the remaining lease payments, discounted at the Company’s incremental borrowing rate. The right-of-use asset is measured at the amount of the lease liability adjusted for the remaining balance of any lease incentives received, any cumulative prepaid or accrued rent if the lease payments are uneven throughout the lease term, any unamortized initial direct costs, and any impairment of the right-of-use-asset. Operating lease expense consists of a single lease cost calculated so that the remaining cost of the lease is allocated over the remaining lease term on a straight-line basis, variable lease payments not included in the lease liability, and any impairment of the right-of-use asset. Certain of the Company’s leases contain options to renew the lease; however, these renewal options are not included in the calculation of the lease liabilities as they are not reasonably certain to be exercised. The Company’s leases do not contain residual value guarantees or material variable lease payments. The Company does not have any material restrictions or covenants imposed by leases that would impact the Company’s ability to pay dividends or cause the Company to incur additional financial obligations. The Company has made an accounting policy election to not apply the recognition requirements in Topic 842 to short-term leases. The Company has also elected to use the practical expedient to make an accounting policy election for property leases to include both lease and nonlease components as a single component and account for it as a lease. The Company’s leases are not complex; therefore there were no significant assumptions or judgements made in applying the requirements of Topic 842, including the determination of whether the contracts contained a lease, the allocation of consideration in the contracts between lease and nonlease components, and the determination of the discount rates for the leases.
Adoption of New Accounting Standards	Adoption of New Accounting Standards In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“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 new standard was adopted by the Company on January 1, 2019. ASU 2016-02 provides for a modified retrospective transition approach requiring lessees to recognize and measure leases on the balance sheet at the beginning of either the earliest period presented or as of the beginning of the period of adoption. The Company elected to apply ASU 2016-02 as of the beginning of the period of adoption (January 1, 2019) and will not restate comparative periods. Adoption of ASU 2016-02 resulted in the recognition of lease liabilities totaling $21,918,000 and the recognition of right-of-use assets totaling $22,123,000 as of the date of adoption. Lease liabilities and right-of-use assets are reflected in other liabilities and other assets, respectively. The initial balance sheet gross up upon adoption was primarily related to operating leases of certain real estate properties. The Company has no finance leases or material subleases or leasing arrangements for which it is the lessor of property or equipment. The Company has elected to apply the package of practical expedients allowed by the new standard under which the Company need not reassess whether any expired or existing contracts are leases or contain leases, the Company need not reassess the lease classification for any expired or existing lease, and the Company need not reassess initial direct costs for any existing leases. Adoption of ASU 2016-02 is not expected to materially change the Company’s recognition of lease expense in future periods. See Note 5 – Premises and Equipment for additional disclosures related to leases.
Newly Issued, But Not Yet Effective Accounting Standards	Newly Issued, But Not Yet Effective Accounting Standards 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”). ASU 2016-13 makes significant changes to the accounting for credit losses on financial instruments and disclosures about them. The new current expected credit loss (CECL) impairment model will require an estimate of expected credit losses, measured over the contractual life of an instrument, which considers reasonable and supportable forecasts of future economic conditions in addition to information about past events and current conditions. The standard provides significant flexibility and requires a high degree of judgment with regards to pooling financial assets with similar risk characteristics, determining the contractual terms of said financial assets and adjusting the relevant historical loss information in order to develop an estimate of expected lifetime 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. The Company will adopt ASU 2016-13 on January 1, 2020. 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. ASU 2016-13 permits the use of estimation techniques that are practical and relevant to the Company’s circumstances, as long as they are applied consistently over time and faithfully estimate expected credit losses in accordance with the standard. The ASU lists several common credit loss methods that are acceptable such as a discounted cash flow (DCF) method, loss-rate method and roll-rate method. Depending on the nature of each identified pool of financial assets with similar risk characteristics, the Company currently plans on implementing a DCF method or a loss-rate method to estimate expected credit losses. The Company expects ASU 2016-13 to have a significant impact on the Company’s accounting policies, internal controls over financial reporting and footnote disclosures. The Company has assessed its data and system needs and has begun designing its financial models to estimate expected credit losses in accordance with the standard. Further development, testing and evaluation of said models is required to determine the impact that adoption of this standard will have on the financial condition and results of operations of the Company.
