Summary of Significant Accounting Policies

NOTE 1 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Operations

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

On March 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.

On March 31, 2017 the Company sold its membership interest in its wholly owned subsidiary Triumph Capital Advisors, LLC (“TCA”).

See Note 2 – Business Combinations and Divestitures for additional information pertaining to the THF and TCA sales and the impact of the transactions on the Company’s consolidated financial statements.

Principles of Consolidation and Basis of Presentation

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

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

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

Use of Estimates

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

Cash and Cash Equivalents

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

Debt Securities

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

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

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

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

Equity Securities

Equity securities are recorded at fair value, with unrealized gains and losses included in earnings beginning January 1, 2018 after adoption of Accounting Standards Update No. 2016-01, “Financial Instruments – Overall: Recognition and Measurement of Financial Assets and Financial Liabilities. Prior to January 1, 2018, unrealized gains and losses on equity securities were excluded from earnings and reported in other comprehensive income (loss), net of tax. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific-identification method.

Loans Held for Sale

The Company elects the fair value option for recording mortgage loans originated and intended for sale in the secondary market in accordance with Accounting Standards Codification (“ASC”) 825, “Financial Instruments”. The fair value of mortgage loans held for sale is determined based on outstanding commitments from investors to purchase such loans and upon prevailing market rates. Increases or decreases in the fair value of these loans held for sale, if any, are charged to earnings through net gains on sale of loans. Mortgage loans held for sale are generally sold with servicing rights released. Gains and losses on sales of mortgage loans are based on the difference between the final selling price and the fair value of the related loan sold.

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

Loans

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

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

Acquired Loans

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

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

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

Factored Receivables

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

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

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

Loan Commitments and Related Financial Instruments

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

Allowance for Loan and Lease Losses

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

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

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

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

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

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

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

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

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

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

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

Farmland — These loans are principally loans to purchase farmland.

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

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

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

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

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

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

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

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

Federal Home Loan Bank (“FHLB”) Stock

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

Premises and Equipment

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

Foreclosed Assets

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

Goodwill

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

The Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining the need to perform the two-step test for goodwill impairment (the qualitative method). If the qualitative method cannot be used or if it determines, based on the qualitative method, that the fair value is more likely than not less than the carrying amount, the Company uses the two-step test. Under the two-step test, the Company compares the estimated fair value of a reporting unit with its carrying amount, including goodwill. If the estimated fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is considered not impaired. If the carrying amount of a reporting unit exceeds its estimated fair value, the second step of the goodwill impairment test is performed to measure the amount of impairment loss, if any. Step two of the goodwill impairment test compares the implied estimated fair value of reporting unit goodwill with the carrying amount of that goodwill. If the carrying amount of goodwill for that reporting unit exceeds the implied fair value of that unit’s goodwill, an impairment loss is recognized in an amount equal to that excess. Our annual goodwill impairment test did not identify any goodwill impairment for the years ended December 31, 2018 and 2017.

Identifiable Intangible Assets

Intangible assets are acquired assets that lack physical substance but can be distinguished from goodwill because of contractual or other legal rights or because the asset is capable of being sold or exchanged either on its own or in combination with a related contract, asset, or liability. The Company's intangible assets primarily relate to core deposits and customer relationships. Intangible assets with definite useful lives are amortized on an accelerated basis over their estimated life. Intangible assets, premises and equipment and other long-lived assets are tested for impairment whenever events or changes in circumstances indicate the carrying amount of the assets may not be recoverable from future undiscounted cash flows. If impaired, the assets are recorded at fair value with a charge to amortization of intangible assets.

Bank Owned Life Insurance

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

Income Taxes

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

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

Fair Values of Financial Instruments

In general, fair values of financial instruments are based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based upon internally developed models that may use, as inputs, observable market-based parameters. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. These adjustments may include amounts to reflect counterparty credit quality and/or the Company’s creditworthiness, among other things, as well as unobservable parameters. Any such valuation adjustments are applied consistently over time. Changes in assumptions or in market conditions could significantly affect these estimates.

In the ordinary course of business, the Company generally does not sell or transfer non-impaired loans and deposits. As such, the disclosures that present the December 31, 2018 and 2017 estimated fair value for non-impaired loans and deposits are highly judgmental and may not represent amounts to be received if the Company were to sell or transfer such items.

Revenue from Contracts with Customers

The Company records revenue from contracts with customers in accordance with Accounting Standards Codification Topic 606, “Revenue from Contracts with Customers” (“Topic 606”). Under Topic 606, the Company must identify the contract with a customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract, and recognize revenue when (or as) the Company satisfies a performance obligation. Significant revenue has not been recognized in the current reporting period that results from performance obligations satisfied in previous periods.

The Company’s primary sources of revenue are derived from interest and dividends earned on loans, investment securities, and other financial instruments that are not within the scope of Topic 606. The Company has evaluated the nature of its contracts with customers and determined that further disaggregation of revenue from contracts with customers into more granular categories beyond what is presented in the Consolidated Statements of Income was not necessary. The Company generally fully satisfies its performance obligations on its contracts with customers as services are rendered and the transaction prices are typically fixed; charged either on a periodic basis or based on activity. Because performance obligations are satisfied as services are rendered and the transaction prices are fixed, the Company has made no significant judgments in applying the revenue guidance prescribed in ASC 606 that affect the determination of the amount and timing of revenue from contracts with customers.

Asset Management Fees

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

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

Operating Segments

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

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

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

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

On March 31, 2017, the Company sold its 100% membership interest in Triumph Capital Advisors, LLC and discontinued fee based asset management services. TCA operations for the years ended December 31, 2017 and 2016 are reflected in the Corporate segment, along with the gain on sale of the Company’s membership interest in TCA.

Comprehensive Income (Loss)

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

Loss Contingencies

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

Transfers of Financial Assets

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

Stock Based Compensation

Compensation cost is recognized for stock based payment awards issued to employees and directors, based on the fair value of these awards at the date of grant. A Black-Scholes model is utilized to estimate the fair value of stock options, a Monte Carlo simulation is utilized to estimate the fair value of performance stock units, and the market price of the Company’s common stock at the date of grant is used for restricted stock awards and restricted stock units. Compensation cost is recognized over the required service period, generally defined as the vesting period. The Company recognizes forfeitures of nonvested awards as they occur.

Earnings Per Common Share

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

Advertising Costs

Advertising costs are expensed as incurred.

Adoption of New Accounting Standards

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

In January 2016, the FASB issued ASU No. 2016-01, “Financial Instruments – Overall: Recognition and Measurement of Financial Assets and Financial Liabilities” (“ASU 2016-01”). The guidance affects the accounting for equity investments, financial liabilities under the fair value option and the presentation and disclosure requirements of financial instruments. ASU 2016-01 was effective for the Company on January 1, 2018 and resulted in separate classification of equity securities previously included in available for sale securities on the consolidated balance sheets with changes in the fair value of the equity securities captured in the consolidated statements of income. See Note 3 – Securities for disclosures related to equity securities. Adoption of the standard also resulted in the use of an exit price rather than an entrance price to determine the fair value of loans not measured at fair value on a non-recurring basis in the consolidated balance sheets. See Note 15 – Fair Value Disclosures for further information regarding the valuation of these loans.

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

Newly Issued, But Not Yet Effective Accounting Standards

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)” (“ASU 2016-02”). The FASB issued this ASU to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet by lessees for those leases classified as operating leases under current U.S. GAAP and disclosing key information about leasing arrangements. The 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 has elected to apply ASU 2016-02 as of the beginning of the period of adoption (January 1, 2019) and will not restate comparative periods. The Company expects that the adoption of ASU 2016-02 will result in the recognition of lease liabilities totaling $21,000,000 to $23,000,000 and the recognition of right-of-use assets totaling $21,000,000 to $23,000,000, which results in a 5- to 7-basis point decrease in the tier 1 capital to risk weighted assets ratio as of the date of adoption. The initial balance sheet gross up upon adoption is primarily related to operating leases of certain real estate properties. The Company has no material leasing arrangements for which it is the lessor of property or equipment. The Company has made an accounting policy election to not apply the recognition requirements in the new standard to short-term leases. 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 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. The Company has also elected to use the practical expedient to make an accounting policy election for leases of certain underlying assets to include both lease and nonlease components as a single component and account for it as a lease. Adoption of ASU 2016-02 is not expected to materially change the Company’s recognition of lease expense in future periods.

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.

Management evaluates 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 December 31, 2018, the Company had 344 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 December 31, 2018, management believes 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 unpaid principal balance is primarily (1) premiums and discounts associated with acquisition date fair value adjustments on acquired loans (both PCI and non-PCI) totaling $19,514,000 and $18,706,000 at December 31, 2018 and 2017, respectively, and (2) net deferred origination and factoring fees totaling $2,579,000 and $2,944,000 at December 31, 2018 and 2017, respectively.

As of December 31, 2018, most of the Company’s non-factoring business activity is with customers located within certain states. The states of Texas (24%), Colorado (27%), Illinois (15%), and Iowa (7%), make up 73% of the Company’s gross loans, excluding factored receivables. Therefore, the Company’s exposure to credit risk is affected by changes in the economies in these states. At December 31, 2017, the states of Texas (24%), Colorado (26%), Illinois (17%), and Iowa (7%) made up 74% of the Company’s gross loans, excluding factored receivables.

A majority (79%) of the Company’s factored receivables, representing approximately 14% of the total loan portfolio as of December 31, 2018, are receivables purchased from trucking fleets, owner-operators, and freight brokers in the transportation industry. At December 31, 2017, 77% of our factored receivables, representing approximately 10% of our total loan portfolio, were receivables purchased from trucking fleets, owner-operators, and freight brokers in the transportation industry.

At December 31, 2018 and 2017, the Company had $58,566,000 and $32,459,000, 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 $847,523,000 and $596,230,000 at December 31, 2018 and 2017, respectively, were pledged to secure Federal Home Loan Bank borrowing capacity.

During the year ended December 31, 2018, a related party loan with a carrying amount of $9,781,000 was transferred to loans held for sale as the Company made the decision to sell the loan. The loan was subsequently sold at its par value for no gain or loss. See Note 16 – Related Party Transactions for further information regarding the sale of the related party loan. During the year ended December 31, 2017, loans with a carrying amount of $3,914,000 were transferred to loans held for sale as the Company made the decision to sell the loans. These loans were subsequently sold resulting in proceeds of $3,834,000 and a loss on sale of loans of $80,000, which was recorded as other noninterest income in the consolidated statements of income. During the year ended December 31, 2016, loans with a carrying amount of $24,384,000 were transferred to loans held for sale as the Company made the decision to sell the loans. These loans were subsequently sold resulting in proceeds of $24,538,000 and a gain on sale of loans of $154,000, which was recorded as other noninterest income in the consolidated statements of income.

Credit Quality Information

The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt, including: current collateral and financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Company analyzes loans individually by classifying the loans as to credit risk. This analysis includes every loan and is performed on a regular basis. Large groups of smaller balance homogeneous loans, such as consumer loans, are analyzed primarily based on payment status. The Company uses the following definitions for risk ratings:

Pass:

Loans classified as pass are loans with low to average risk and not otherwise classified as substandard or doubtful.

Substandard:

Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the repayment of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected.

Doubtful:

Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable.

PCI:

At acquisition, PCI loans had the characteristics of substandard loans and it was probable, at acquisition, that all contractually required principal payments would not be collected. The Company evaluates these loans on a projected cash flow basis with this evaluation performed quarterly.

As of December 31, 2018 and 2017 based on the most recent analysis performed, the risk category of loans is as follows:

No goodwill or intangibles have been assigned to the Corporate operating segment.

Impairment exists when a reporting unit’s carrying value of goodwill exceeds its fair value. The Company assesses goodwill for impairment at its reporting units that contain goodwill, Banking and Factoring. At the measurement date, these reporting units had positive equity and the Company elected to perform qualitative assessments to determine if it was more likely than not that the fair value of the reporting units exceeded their carrying values, including goodwill. The qualitative assessment indicated that it was more likely than not that the fair value of the reporting unit exceeded its carrying value, resulting in no impairment.

After performing an impairment test comparing the carrying value of intangible assets to the fair value of intangible assets during the years ended December 31, 2018 and 2016, it was determined that the fair value of the intangible assets exceeded their carrying amount and thus, no intangible asset impairment was recorded. During the year ended December 31, 2017, it was determined that the carrying amount of core deposit intangibles related to public funds assigned to the Banking segment exceeded the fair value of these core deposit intangibles, resulting in an impairment charge of $1,276,000 for the year ended December 31, 2017. The impairment charge was recorded as amortization expense in the consolidated statements of income. The impairment of the core deposit intangibles was a result of the decline in public funds deposit balances caused by the Company’s intentional decision to reduce its reliance on the use of public funds.

Generally, material acquired intangible assets are being amortized utilizing an accelerated method over their estimated useful lives, which range from 8 to 10 years. The future amortization schedule for the Company’s intangible assets is as follows:

Variable Interest Entities

NOTE 8 — VARIABLE INTEREST ENTITIES

Collateralized Loan Obligation Funds - Closed

The Company, through its subsidiary Triumph Capital Advisors, acted as the asset manager or provided certain middle and back office staffing and services to the asset manager of various CLO funds. TCA earned asset management fees in accordance with the terms of its asset management or staffing and services agreements associated with the CLO funds. TCA earned asset management fees totaling $1,717,000, and $6,574,000 for the years ended December 31, 2017, and 2016. On March 31, 2017, the Company sold its membership interests in TCA as discussed in Note 2 – Business Combinations and Divestitures. As a result of the TCA sale, as of March 31, 2017 the Company no longer acted as asset manager or staffing and services provider for any CLO funds.

The Company holds investments in the subordinated notes of the following closed CLO funds:

	Offering	Offering
(Dollars in thousands)	Date	Amount
Trinitas CLO IV, LTD (Trinitas IV)	June 2, 2016	$	406,650
Trinitas CLO V, LTD (Trinitas V)	September 22, 2016	$	409,000
Trinitas CLO VI, LTD (Trinitas VI)	June 20, 2017	$	717,100

The carrying amounts of the Company’s investments in the subordinated notes of the CLO funds, which represent the Company’s maximum exposure to loss as a result of its involvement with the CLO funds, totaled $8,487,000 and $8,557,000 at December 31, 2018 and 2017, 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 are variable interest entities and that the Company holds variable interests in the entities in the form of its investments in the subordinated notes of the entities. However, the Company also concluded that the Company does not have the power to direct the activities that most significantly impact the entities’ economic performance. As a result, the Company is not the primary beneficiary and therefore is not required to consolidate the assets, liabilities, equity or operations of the CLO funds in the Company’s financial statements.

Collateralized Loan Obligation Funds – Warehouse Phase

From time to time, the Company may invest in the subordinated debt of entities formed to be the issuers of CLO offerings during their warehouse phases. The Company’s investments in these CLO funds are repaid when the CLO funds’ warehouse phases are closed and the CLO offerings are issued. The Company’s maximum exposure to loss as a result of its involvement with these CLO funds is limited to the carrying amount of its investments in the subordinated debt of the CLO funds. The Company did not hold any investments in the subordinated debt of CLO funds during their warehouse phase at December 31, 2018 and 2017, or during the year ended December 31, 2018. Income from the Company’s investments in CLO warehouse entities totaled $2,226,000 and $3,184,000 during the years ended December 31, 2017 and 2016, respectively, and is included in other noninterest income within the Company’s consolidated statements of income.

The Company performed a consolidation analysis of CLO funds during their warehouse phases and concluded that the CLO funds were variable interest entities and that the Company held a variable interest in the entities that could potentially be significant to the entities in the form of its investments in the subordinated notes of the entities. However, the Company also concluded that the Company did 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 entities in the Company’s financial statements.

The Notes initially bear interest at 6.50% per annum, payable semi-annually in arrears, to, but excluding, September 30, 2021, and, thereafter and to, but excluding, the maturity date or earlier redemption, interest shall be payable quarterly in arrears, at an annual floating rate equal to three-month LIBOR as determined for the applicable quarterly period, plus 5.345%. The Company may, at its option, beginning on September 30, 2021 and on any scheduled interest payment date thereafter, redeem the Notes, in whole or in part, at a redemption price equal to the outstanding principal amount of the Notes to be redeemed plus accrued and unpaid interest to, but excluding, the date of redemption. The Notes are subordinated in right of payment to the Company’s existing and future senior indebtedness and are structurally subordinated to the Company’s subsidiaries’ existing and future indebtedness and other obligations.

The Notes are included on the consolidated balance sheets as liabilities at their carrying values of $48,929,000 and $48,828,000 at December 31, 2018 and 2017, respectively; however, for regulatory purposes, the carrying value of these obligations were eligible for inclusion in Tier 2 regulatory capital.

Issuance costs related to the Notes totaled $1,324,000, including an underwriting discount of 1.5%, or $750,000, and have been netted against the subordinated notes liability on the balance sheet. The underwriting discount and other debt issuance costs are being amortized using the effective interest method through maturity and recognized as a component of interest expense.

Junior Subordinated Debentures

The following provides a summary of the Company’s junior subordinated debentures:

						Variable	Interest Rate At
(Dollars in thousands)	Face Value		Carrying Value		Maturity Date	Interest Rate	December 31, 2018
National Bancshares Capital Trust II	$	15,464	$	12,975	September 2033	LIBOR + 3.00%	5.79%
National Bancshares Capital Trust III		17,526		12,576	July 2036	LIBOR + 1.64%	4.08%
ColoEast Capital Trust I		5,155		3,478	September 2035	LIBOR + 1.60%	4.40%
ColoEast Capital Trust II		6,700		4,554	March 2037	LIBOR + 1.79%	4.59%
Valley Bancorp Statutory Trust I		3,093		2,855	September 2032	LIBOR + 3.40%	6.22%
Valley Bancorp Statutory Trust II		3,093		2,645	July 2034	LIBOR + 2.75%	5.54%
	$	51,031	$	39,083

These debentures are unsecured obligations due to trusts that are unconsolidated subsidiaries. The debentures were issued in conjunction with the trusts’ issuances of obligated capital securities. The trusts used the proceeds from the issuances of their capital securities to buy floating rate junior subordinated deferrable interest debentures that bear the same interest rate and terms as the capital securities. These debentures are the trusts’ only assets and the interest payments from the debentures finance the distributions paid on the capital securities. These debentures rank junior and are subordinate in the right of payment to all other debt of the Company.

As part of the purchase accounting adjustments made with the National Bancshares, Inc. acquisition on October 15, 2013, the ColoEast acquisition on August 1, 2016, and the Valley acquisition on December 9, 2017, the Company adjusted the carrying value of the junior subordinated debentures to fair value as of the respective acquisition dates. The discount on the debentures will continue to be amortized through maturity and recognized as a component of interest expense.

The debentures may be called by the Company at par plus any accrued but unpaid interest. Interest on the debentures is calculated quarterly. The distribution rate payable on the capital securities is cumulative and payable quarterly in arrears. The Company has the right to defer payments on interest on the debentures at any time by extending the interest payment period for a period not exceeding 20 consecutive quarters with respect to each deferral period, provided that no extension period may extend beyond the redemption or maturity date of the debentures.

The debentures are included on the consolidated balance sheet as liabilities; however, for regulatory purposes, the carrying value of these obligations are eligible for inclusion in Tier I regulatory capital, subject to certain limitations. All of the carrying value of $39,083,000 and $38,623,000 was allowed in the calculation of Tier I regulatory capital as of December 31, 2018 and 2017, respectively.

⁽¹⁾ On December 22, 2017, the United States enacted tax reform legislation commonly known as the Tax Cuts and Jobs Act (the “Tax Act”), resulting in significant modifications to existing law. As a result of the changes under the Tax Act, the Company recorded incremental income tax expense of $2,984,000 during the year ended December 31, 2017, which consisted primarily of the remeasurement of deferred tax assets and liabilities at the new federal statutory rate of 21%. Prior to the enactment of the Tax Act, deferred tax assets and liabilities were measured at the previous federal statutory rate of 35%.

Deferred income taxes reflect the net tax effects of temporary differences between the recorded amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of the Company’s deferred tax assets and liabilities are as follows:

(Dollars in thousands)	2018			2017

The Company's federal and state net operating loss carryforwards as of December 31, 2018 were $29,102,000 and $16,829,000, respectively, which will expire at various dates from 2021 through 2035. The Company has a Federal Alternative Minimum Tax Credit carryforward of $2,855,000 as of December 31, 2018 with no expiration. The Company has a valuation allowance on certain net operating loss carryforwards that are not expected to be realized before expiration.

The Company's federal and state net operating loss carryforwards as of December 31, 2017 were $34,190,000 and $23,641,000, respectively. The Company had a Federal Alternative Minimum Tax Credit carryforward of $2,855,000 as of December 31, 2017.

An Internal Revenue Code Section 382 (“Section 382”) ownership change was triggered as part of previous acquisitions. A significant portion of the deferred tax asset relating to the Company's net operating loss and Alternative Minimum Tax credit carryforwards are subject to the annual limitation rules under Section 382 . The utilization of tax carryforward attributes acquired from the EJ Financial Corp. (2010) acquisition is subject to an annual limitation of $341,000. The utilization of tax carryforward attributes acquired from the National Bancshares, Inc.(2013) acquisition is subject to an annual limitation of $2,040,000. Any remaining tax attribute carryforwards generated prior to the Section 382 ownership change in 2013 are subject to an annual limitation of $3,696,000.

The utilization of deferred tax assets related to the net operating loss and tax credit carryforwards acquired from the 2016 ColoEast stock acquisition are subject to an annual limitation of $1,906,000 under Section 382 rules.

At December 31, 2018 and 2017, the Company had no amounts recorded for uncertain tax positions and does not expect any material changes in uncertain tax benefits during the next 12 months. The Company recognizes interest and penalties related to income tax matters in income tax expense.

The Company is subject to U.S. federal income tax as well as income tax in various states. The Company is generally not subject to examination by taxing authorities for years prior to 2015.

Off-Balance Sheet Loan Commitments

NOTE 14 - 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 instruments.

The contractual amounts of financial instruments with off-balance sheet risk were as follows:

	December 31, 2018						December 31, 2017
	Fixed		Variable				Fixed		Variable
(Dollars in thousands)	Rate		Rate		Total		Rate		Rate		Total
Unused lines of credit	$	69,053	$	433,667	$	502,720	$	133,634	$	242,236	$	375,870
Standby letters of credit	$	2,285	$	3,931	$	6,216	$	1,998	$	8,169	$	10,167
Mortgage warehouse commitments	$	—	$	266,458	$	266,458	$	—	$	239,632	$	239,632

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 a reserve 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 December 31, 2018 and 2017, the reserve for loan and lease losses on off-balance sheet lending-related commitments totaled $538,000 and $501,000, respectively, and was included in other liabilities on the Company’s consolidated balance sheets.

In addition to the commitments above, the Company had overdraft protection available in the amounts of $3,087,000 and $2,397,000 at December 31, 2018 and 2017, respectively.

Fair Value Disclosures [Abstract]

Fair Value Disclosures

NOTE 15 - 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.

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

There were no liabilities measured at fair value on a recurring basis at December 31, 2017.

The Company used the following methods and assumptions to estimate fair value of financial instruments that are measured at fair value on a recurring basis:

Securities available for sale – The fair values of debt securities available for sale are determined by third party matrix pricing, which is a mathematical technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2 inputs).

Equity securities – The fair values of equity securities are determined based on quoted market prices in active markets and are classified in Level 1 of the valuation hierarchy.

Loans held for sale – Loans held for sale represent mortgage loan originations intended to be sold in the secondary market. The fair value of loans held for sale is determined using commitments on hand from investors or prevailing market prices and are classified in Level 2 of the valuation hierarchy.

ICC contingent consideration – The fair value of the ICC 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. The fair value is classified in Level 3 of the valuation hierarchy. ICC contingent consideration was initially recorded with an acquisition date fair value of $20,000,000. Subsequent to acquisition, the contingent consideration increased in fair value by $745,000 to a fair value of $20,745,000 at December 31, 2018. There were no disposals of contingent consideration during the period. 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.

There were no transfers between levels for the years ended December 31, 2018 and 2017.

Assets measured at fair value on a non-recurring basis are summarized in the table below. There were no liabilities measured at fair value on a non-recurring basis at December 31, 2018 and 2017.

As of December 31, 2018 and 2017, the only Level 3 assets with material unobservable inputs are associated with impaired loans and OREO.

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 were as follows:

For those financial instruments not previously described, the following methods and assumptions were used by the Company in estimating the fair values of financial instruments as disclosed herein:

Cash and Cash Equivalents

For financial instruments with a shorter term or with no stated maturity, prevailing market rates, and limited credit risk, the carrying amounts approximate fair value and are considered a Level 1 classification.

Securities held to maturity

The fair values of the Company’s investments in the subordinated notes of Trinitas IV, Trinitas V, and Trinitas VI classified as securities held to maturity are determined based on the securities’ discounted projected future cash flows (net present value), resulting in a Level 3 classification.

The fair values of the Company’s other securities held to maturity at December 31, 2016 were determined by third party matrix pricing, which is a mathematical technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities, resulting in a Level 2 classification. There were no such securities held at December 31, 2017.

Loans

Loans include loans held for investment and loans included in assets held for sale. Loans exclude impaired loans previously described above. For variable rate loans that reprice frequently and have no significant changes in credit risk, excluding previously presented impaired loans measured at fair value on a non-recurring basis, fair values are based on carrying values. Fair values for fixed rate loans are estimated using discounted cash flow analyses. In accordance with ASU 2016-01, which was adopted effective January 1, 2018, the discount rates used to determine the fair value of loans at December 31, 2018 use interest rate spreads that reflect factors such as liquidity, credit, and nonperformance risk of the loans. The discount rates used to determine the fair value of loans at December 31, 2017 were based on interest rates currently being offered for loans with similar terms to borrowers of similar credit quality. Loans are considered a Level 3 classification.

FHLB stock

FHLB stock is restricted to member banks and there are restrictions placed on its transferability. As a result, the fair value of FHLB stock was not practicable to determine.

Deposits

The fair values disclosed for demand deposits and non-maturity transaction accounts are, by definition, equal to the amount payable on demand at the reporting date (that is, their carrying amounts) and are considered a Level 2 classification. Fair values for fixed rate time deposits are estimated using a discounted cash flow calculation that applies interest rates currently being offered on time deposits to a schedule of aggregated expected monthly maturities on time deposits resulting in a Level 2 classification.

Customer repurchase agreements

The carrying amount of customer repurchase agreements approximates fair value due to their short term nature. The customer repurchase agreement fair value is considered a Level 2 classification.

Federal Home Loan Bank advances

The Company’s FHLB advances have variable rates or a maturity of less than three months and therefore fair value materially approximates carrying value and is considered a Level 2 classification.

Subordinated notes

The subordinated notes were valued based on quoted market prices, but due to limited trading activity for the subordinated notes in these markets, the subordinated notes are considered a Level 2 classification.

Junior subordinated debentures

The junior subordinated debentures were valued by discounting future cash flows using current interest rates for similar financial instruments, resulting in a Level 2 classification.

Accrued Interest Receivable and Accrued Interest Payable

The carrying amounts of accrued interest receivable and accrued interest payable approximate their fair values given the short term nature of the receivables and are considered a Level 1 classification.

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

Related-Party Transactions

NOTE 16 — RELATED-PARTY TRANSACTIONS

Loans to executive officers, directors, and their affiliates were as follows:

	Years Ended December 31,
(Dollars in thousands)	2018			2017
Beginning balance	$	26,612		$	29,285
New loans and advances		28,526			14,440

Repayments and sales		(15,618	)		(2,109	)
Ending balance	$	39,520		$	26,612

These loans are made in the ordinary course of business and on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with other unaffiliated persons and do not involve more than normal risk of collectability.

In December 2018, the Company sold a loan with an aggregate principal balance of $9,781,000 to an entity in which a director, together with members of his family, have a majority interest. The loan, which was originated as a Regulation O related party loan due to the interests of such director in the borrower for such loan, was sold at a purchase price equal to 100% of the outstanding principal balance of the loan plus accrued interest and therefore, resulted in no gain or loss for the year ended December 31, 2018. The loan was sold by the Company due to credit deterioration at the borrower which would have caused the loan to be classified as a substandard non-performing loan had it remained on the Company’s balance sheet as of December 31, 2018.

At December 31, 2018, there were no loans to executive officers, directors, or their affiliates that were considered non-performing or potential problem loans.

Deposits from executive officers, directors, and their affiliates at December 31, 2018 and 2017 were $6,176,000 and $9,360,000, respectively.

Regulatory Capital Requirements [Abstract]

Regulatory Matters

NOTE 17 — 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 December 31, 2018, the Company and TBK Bank meet all capital adequacy requirements to which they are subject.

As of 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 December 31, 2018 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:

								To Be Well
								Capitalized Under
				Minimum for Capital				Prompt Corrective
	Actual			Adequacy Purposes				Action Provisions
(Dollars in thousands)	Amount		Ratio	Amount		Ratio		Amount		Ratio
As of December 31, 2018

TBK Bank, SSB	$	496,526	12.4%	$	320,856		8.0%	$	401,071		10.0%

TBK Bank, SSB	$	341,910	11.1%	$	123,088		4.0%	$	153,860		5.0%

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

- Definition

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 were determined based on the historical volatilities of the Company and the specified peer group. The risk-free interest rate for the performance period was derived from the Treasury constant maturities yield curve on the valuation date.

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. The fair value of stock options granted is estimated at the date of grant using the Black-Scholes option-pricing model. Expected volatilities of options granted during the year ended December 31, 2018 and 2017 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. Expected volatilities of options granted during the year ended December 31, 2016 were determined based on 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:

	2018			2017			2016
Risk-free interest rate		2.85	%		2.11	%		1.49	%
Expected term	6.25 years			6.25 Years			6.25 Years
Expected stock price volatility		28.07	%		29.70	%		34.96	%
Dividend yield		—			—			—

As of December 31, 2018, there was $654,000 of unrecognized compensation cost related to nonvested stock options. The cost is expected to be recognized over a remaining weighted average period of 2.88 years.

Business Segment Information

NOTE 22 – BUSINESS SEGMENT INFORMATION

The following presents the Company’s operating segments. The accounting policies of the segments are the same as those described in Note 1 – Summary of Significant Accounting Policies. Transactions between segments consist primarily of borrowed funds. Intersegment interest expense is allocated to the Factoring segment based on the Company’s prime rate. The provision for loan loss is allocated based on the segment’s ALLL determination. Noninterest income and expense directly attributable to a segment are assigned to it. Taxes are paid on a consolidated basis but not allocated for segment purposes. The Factoring segment includes only factoring originated by TBC. General factoring services not originated through TBC are included in the Banking segment. On March 31, 2017, the Company sold its 100% membership interest in Triumph Capital Advisors, LLC (“TCA”) and discontinued fee based asset management services. TCA operations for the years ended December 31, 2017 and 2016 are reflected in the Corporate segment, along with the gain on sale of the Company’s membership interest in TCA.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
Summary of Significant Accounting Policies (Policies)	Dec. 31, 2018
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 factoring subsidiary Advance Business Capital LLC, which currently operates under the d/b/a of Triumph Business Capital (“TBC”), and TBK Bank’s wholly owned subsidiary Triumph Insurance Group, Inc. (“TIG”). On March 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. On March 31, 2017 the Company sold its membership interest in its wholly owned subsidiary Triumph Capital Advisors, LLC (“TCA”). See Note 2 – Business Combinations and Divestitures for additional information pertaining to the THF and TCA sales and the impact of the transactions on the Company’s consolidated financial statements.
Principles of Consolidation and Basis of Presentation	Principles of Consolidation and Basis of Presentation The Company consolidates subsidiaries in which it holds, directly or indirectly, a controlling financial interest. The Company determines whether it has a controlling financial interest in an entity by first evaluating whether the entity is a voting interest entity or a variable interest entity under U.S. generally accepted accounting principles (“GAAP”). Voting interest entities are entities in which the total equity investment at risk is sufficient to enable the entity to finance itself independently and provides the equity holders with the obligation to absorb losses, the right to receive residual returns and the right to make decisions about the entity’s activities. The Company consolidates voting interest entities in which it has at least a majority of the voting interest. Variable interest entities (“VIEs”) are entities that lack one or more of the characteristics of a voting interest entity. A controlling financial interest in a VIE is present when an enterprise has both the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and an obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. The enterprise with a controlling financial interest, known as the primary beneficiary, consolidates the VIE. In consolidation, all significant intercompany accounts and transactions are eliminated. Investments in unconsolidated entities are accounted for using the equity method of accounting when the Company has the ability to exercise significant influence over operating and financing decisions. Investments that do not meet the criteria for equity method accounting are accounted for using the cost method of accounting. The accounting and reporting policies of the Company and its subsidiaries conform to GAAP and general practice within the banking industry. Certain reclassifications have been made to prior year amounts to conform to the current year presentation. The Company uses the accrual basis of accounting for financial reporting purposes.
Use of Estimates	Use of Estimates To prepare financial statements in conformity with GAAP management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided, and actual results could differ.
Cash and Cash Equivalents	Cash and Cash Equivalents For the purposes of reporting cash flows, cash and cash equivalents include cash on hand, amounts due from banks, other short term investments and federal funds sold. All highly liquid investments with an initial maturity of less than 90 days are considered to be cash equivalents. Certain items, including loan and deposit transactions, customer repurchase agreements, and FHLB advances and repayments, are presented net in the statement of cash flows.
Debt Securities	Debt Securities The Company determines the classification of debt securities at the time of purchase. Debt securities that management has the positive intent and ability to hold to maturity are classified as held to maturity and recorded at amortized cost. Trading securities are recorded at fair value with changes in fair value included in earnings. Debt securities not classified as held to maturity or trading are classified as available for sale and recorded at fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive income (loss), net of tax. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific-identification method. Amortization of premiums and discounts are recognized in interest income over the period to maturity using the interest method. Management evaluates securities for other-than-temporary impairment (“OTTI”) on a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. For securities in an unrealized loss position, management considers the extent and duration of the unrealized loss, and the financial condition and near-term prospects of the issuer. Management also assesses whether it intends to sell, or it is more likely than not that it will be required to sell, a security in an unrealized loss position before recovery of its amortized cost basis. In analyzing an issuer’s financial condition, the Company may consider whether the securities are issued by the federal government or its agencies, whether downgrades by bond rating agencies have occurred, and the results of reviews of the issuers’ financial condition. The Company conducts regular reviews of the bond agency ratings of securities and considers whether the securities were issued by or have principal and interest payments guaranteed by the federal government or its agencies. These reviews focus on the underlying rating of the issuer and also include the insurance rating of securities that have an insurance component or guarantee. The ratings and financial condition of the issuers are monitored, as well as the financial condition and ratings of the insurers and guarantors. If either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost and fair value is recognized as impairment through earnings. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: 1) OTTI related to credit loss, which must be recognized through earnings, and 2) OTTI related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. For equity securities, the entire amount of impairment is recognized through earnings.
Equity Securities	Equity Securities Equity securities are recorded at fair value, with unrealized gains and losses included in earnings beginning January 1, 2018 after adoption of Accounting Standards Update No. 2016-01, “Financial Instruments – Overall: Recognition and Measurement of Financial Assets and Financial Liabilities. Prior to January 1, 2018, unrealized gains and losses on equity securities were excluded from earnings and reported in other comprehensive income (loss), net of tax. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific-identification method.
Loans Held for Sale	Loans Held for Sale The Company elects the fair value option for recording mortgage loans originated and intended for sale in the secondary market in accordance with Accounting Standards Codification (“ASC”) 825, “Financial Instruments”. The fair value of mortgage loans held for sale is determined based on outstanding commitments from investors to purchase such loans and upon prevailing market rates. Increases or decreases in the fair value of these loans held for sale, if any, are charged to earnings through net gains on sale of loans. Mortgage loans held for sale are generally sold with servicing rights released. Gains and losses on sales of mortgage loans are based on the difference between the final selling price and the fair value of the related loan sold. Management occasionally transfers non-mortgage loans from held for investment to held for sale. Gains or losses on the sale of these loans are recorded in noninterest income.
Loans	Loans Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at the unpaid principal balance outstanding, net of unearned income, deferred loan fees and costs, and any direct principal charge-offs. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized in interest income over the remaining life of the loan without anticipating prepayments. Loans are considered past due or delinquent when the contractual principal or interest due in accordance with the terms of the loan agreement or any portion thereof remains unpaid after the due date of the scheduled payment. Loans are classified as nonaccrual when, in the opinion of management, collection of principal or interest is doubtful. The accrual of interest income on loans is typically discontinued at the time the loan is 90 days delinquent unless the loan is well-secured and in process of collection, or if full collection of interest or principal becomes uncertain. Consumer loans are typically charged off no later than 120 days past due. Past due status is based on the contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged-off at an earlier date if collection of principal or interest is considered doubtful. All interest accrued but not received for a loan placed on nonaccrual is reversed against interest income. Interest received on such loans is accounted for on the cash-basis or cost recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. Acquired Loans Acquired loans are recorded at fair value at the date of acquisition with no initial valuation allowance based on a discounted cash flow methodology that considers various factors including the type of loan and related collateral, classification status, fixed or variable interest rate, term of loan and whether or not the loan was amortizing, and a discount rate reflecting the Company’s assessment of risk inherent in the cash flow estimates. Certain larger purchased loans are individually evaluated while certain purchased loans are grouped together according to similar risk characteristics and are treated in the aggregate when applying various valuation techniques. These cash flow evaluations are inherently subjective as they require material estimates, all of which may be susceptible to significant change. Loans acquired in a business combination that have evidence of deterioration of credit quality since origination and for which it is probable, at acquisition, that the Company will be unable to collect all contractually required payments receivable are considered purchased credit impaired (“PCI”). PCI loans are individually evaluated and recorded at fair value at the date of acquisition with no initial valuation allowance based on a discounted cash flow methodology that considers various factors including the type of loan and related collateral, classification status, fixed or variable interest rate, term of loan and whether or not the loan was amortizing, and a discount rate reflecting the Company’s assessment of risk inherent in the cash flow estimates. The difference between the undiscounted cash flows expected at acquisition and the investment in the loan, or the “accretable yield,” is recognized as interest income on a level-yield method over the life of the loan. Contractually required payments for interest and principal that exceed the undiscounted cash flows expected at acquisition, or the “nonaccretable difference,” are not recognized on the balance sheet and do not result in any yield adjustments, loss accruals or valuation allowances. Increases in expected cash flows, including prepayments, subsequent to the initial investment are recognized prospectively through adjustment of the yield on the loan over its remaining life. Decreases in expected cash flows are recognized as impairment. Valuation allowances on PCI loans reflect only losses incurred after the acquisition (meaning the present value of all cash flows expected at acquisition that ultimately are not to be received). For acquired loans not deemed credit-impaired at acquisition, the differences between the initial fair value and the unpaid principal balance are recognized as interest income on a level-yield basis over the lives of the related loans. Subsequent to the acquisition date, methods utilized to estimate the required allowance for loan and lease losses for these loans is similar to originated loans; however, a provision for credit losses will be recorded only to the extent the required allowance exceeds any remaining purchase discounts. Once an acquired loan undergoes new underwriting and meets the criteria for a new loan, such as in the case of a loan renewal, any remaining fair value adjustments are accreted into interest income and the loan establishes a new amortized cost basis that is fully subject to the Company's allowance for loan and lease loss methodology. Factored Receivables The Company purchases invoices from its factoring clients in schedules or batches. Cash is advanced to the client to the extent of the applicable advance rate, less fees, as set forth in the individual factoring agreements. The face value of the invoices purchased are recorded by the Company as factored receivables, and the unadvanced portions of the invoices purchased, less fees, are considered client reserves. The client reserves are held to settle any payment disputes or collection shortfalls, may be used to pay clients’ obligations to various third parties as directed by the client, are periodically released to or withdrawn by clients, and are reported as deposits. Unearned factoring fees and unearned net origination fees are deferred and recognized over the weighted average collection period for each client. Subsequent factoring fees are recognized in interest income as incurred by the client and deducted from the clients’ reserve balances. Other factoring-related fees, which include wire transfer fees, carrier payment fees, fuel advance fees, and other similar fees, are reported by the Company as non-interest income as incurred by the client.
Loan Commitments and Related Financial Instruments	Loan Commitments and Related Financial Instruments Financial instruments include off-balance sheet credit instruments, such as commitments to make loans and commercial letters of credit, issued to meet customer financing needs. The face amount for these items represents the exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded.
Allowance for Loan and Lease Losses	Allowance for Loan and Lease Losses The allowance for loan and lease losses (the “ALLL”) is a valuation allowance maintained to cover incurred losses that are estimated in accordance with US GAAP. It is our estimate of credit losses inherent in our loan portfolio at each balance sheet date. Our methodology for analyzing the allowance for loan and lease losses consists of general and specific components. For the general component, we stratify the loan portfolio into homogeneous groups of loans that possess similar loss potential characteristics and apply a loss ratio to these groups of loans to estimate the credit losses in the loan portfolio. We use both historical loss ratios and qualitative loss factors assigned to major loan collateral types to establish general component loss allocations. Qualitative loss factors are based on management's judgment of company, market, industry or business specific data and external economic indicators, which are not yet reflected in the historical loss ratios, and that could impact the Company's loan portfolios. Management sets and adjusts qualitative loss factors by regularly reviewing changes in underlying loan composition of specific portfolios. Management also considers credit quality and trends relating to delinquency, non-performing and adversely rated loans within the Company's loan portfolio when evaluating qualitative loss factors. Additionally, management adjusts qualitative factors to account for the potential impact of external economic factors and other pertinent economic data specific to our primary market area and lending portfolios. For the specific component, the allowance for loan and lease losses includes loans where management has concerns about the borrower's ability to repay and on individually analyzed loans found to be impaired. Management evaluates current information and events regarding a borrower's ability to repay its obligations and considers a loan to be impaired when the ultimate collectability of amounts due, according to the contractual terms of the loan agreement, is in doubt. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. If an impaired loan is collateral-dependent, the fair value of the collateral, less the estimated cost to sell, is used to determine the amount of impairment. If an impaired loan is not collateral-dependent, the impairment amount is determined using the negative difference, if any, between the estimated discounted cash flows and the loan amount due. For impaired loans, the amount of the impairment can be adjusted, based on current data, until such time as the actual basis is established by acquisition of the collateral or until the basis is collected. Impairment losses are reflected in the allowance for loan and lease losses through a charge to the provision for credit losses. Subsequent recoveries are credited to the allowance for loan and lease losses. Cash receipts for accruing loans are applied to principal and interest under the contractual terms of the loan agreement. Cash receipts on impaired loans for which the accrual of interest has been discontinued are applied first to principal. Loan losses are charged against the ALLL when management believes the uncollectability of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the ALLL. Allocations of the ALLL may be made for specific loans, but the entire allowance is available for any loan that, in management’s judgment, should be charged-off. Large groups of smaller balance homogeneous loans are collectively evaluated for impairment, and accordingly, they are not separately identified for impairment disclosures. The Company considers these loans to be homogeneous in nature due to the smaller dollar amount and the similar underwriting criteria. PCI loans are not considered impaired on the acquisition date. For PCI loans, a decline in the present value of current expected cash flows compared to the previously estimated expected cash flows, due in any part to change in credit, is considered an impairment event and a provision for loan losses will be recorded during the period as necessary. A loan that has been modified or renewed is considered a troubled debt restructuring (“TDR”) when two conditions are met: 1) the borrower is experiencing financial difficulty and 2) concessions are made for the borrower's benefit that would not otherwise be considered for a borrower or transaction with similar credit risk characteristics. TDRs are separately identified for impairment and are measured at the present value of estimated future cash flows using the loan’s effective rate at inception. If a TDR is considered to be a collateral dependent loan, the loan is reported, net, at the fair value of the collateral up to the carrying amount of the loan. For TDRs that subsequently default, the Company determines the amount of reserve in accordance with the accounting policy for the ALLL. The following loan portfolio categories have been identified for purposes of determining the general component of the ALLL: Commercial Real Estate — This category of loans consists of the following loan types: Non-farm Non-residential — This category includes real estate loans for a variety of commercial property types and purposes, including owner occupied commercial real estate loans primarily secured by commercial office or industrial buildings, warehouses or retail buildings where the owner of the building occupies the property. Repayment terms vary considerably, interest rates are fixed or variable, and are structured for full, partial, or no amortization of principal. This category also includes investment real estate loans that are primarily secured by office and industrial buildings, warehouses, small retail shopping centers and various special purpose properties. Generally, these types of loans are thought to involve a greater degree of credit risk than owner occupied commercial real estate as they are more sensitive to adverse economic conditions. Multi-family residential — Investment real estate loans are primarily secured by non-owner occupied apartment or multifamily residential buildings. Generally, these types of loans are thought to involve a greater degree of credit risk than owner occupied commercial real estate as they are more sensitive to adverse economic conditions. Construction, land development, land —This category of loans consists of loans to finance the ground up construction, improvement and/or carrying for sale after the completion of construction of owner occupied and non-owner occupied residential and commercial properties, and loans secured by raw or improved land. The repayment of construction loans is generally dependent upon the successful completion of the improvements by the builder for the end user, or sale of the property to a third party. Repayment of land secured loans are dependent upon the successful development and sale of the property, the sale of the land as is, or the outside cash flow of the owners to support the retirement of the debt. 1-4 family residential properties — This category of loans includes both first and junior liens on residential real estate. Home equity revolving lines of credit and home equity term loans are included in this group of loans. Farmland — These loans are principally loans to purchase farmland. Commercial — Commercial loans are loans for commercial, corporate and business purposes. The Company’s commercial business loan portfolio is comprised of loans for a variety of purposes and across a variety of industries. These loans include general commercial and industrial loans, loans to purchase capital equipment, agriculture operating loans and other business loans for working capital and operational purposes. Commercial loans are generally secured by accounts receivable, inventory and other business assets. Commercial loans also include shared national credits purchased by the Company. A portion of the commercial loan portfolio consists of specialty commercial finance products as follows: Equipment — Equipment finance loans are commercial loans primarily secured by new or used revenue producing, essential-use equipment from major manufacturers that is movable, may be used in more than one type of business, and generally has broad resale markets. Core markets include transportation, construction, and waste. Loan terms do not exceed the economic life of the equipment and typically are 60 months or less. Asset-based Lending — These loans are originated to borrowers to support general working capital needs. The asset-based loan structure involves advances of loan proceeds against a borrowing base which typically consists of accounts receivable, identified readily marketable inventory, or other collateral of the borrower. The maximum amount a customer may borrow at any time is fixed as a percentage of the borrowing base outstanding. Premium Finance — Loans that provide customized premium financing solutions for the acquisition of property and casualty insurance coverage. In effect, these short term premium finance loans allow insureds to pay their insurance premiums over the life of the underlying policy, instead of paying the entire premium at the outset. Factored Receivables — The Company operates as a factor by purchasing accounts receivable from its clients, then collecting the receivable from the account debtor. The Company’s smaller factoring relationships are typically structured as “non-recourse” relationships (i.e., the Company retains the credit risk associated with the ability of the account debtor on a purchased invoice to ultimately make payment) and the Company’s larger factoring relationships are typically structured as “recourse” relationships (i.e., the Company’s client agrees to repurchase any invoices for which payment is not ultimately received from the account debtor). Advances initially made to the client to acquire the receivables are typically at a discount to the invoice value. The discount balance is held in client reserves, net of the Company’s compensation. The client reserves are held to settle any payment disputes or collection shortfalls, may be used to pay clients’ obligations to various third parties as directed by the client, are periodically released to or withdrawn by clients, and are reported as deposits. Consumer — Loans used for personal use typically on an unsecured basis. Mortgage Warehouse — Mortgage Warehouse facilities are provided to unaffiliated mortgage origination companies and are collateralized by 1-4 family residential loans. The originator closes new mortgage loans with the intent to sell these loans to third party investors for a profit. The Company provides funding to the mortgage companies for the period between the origination and their sale of the loan. The Company has a policy that requires that it separately validate that each residential mortgage loan was underwritten consistent with the underwriting requirements of the final investor or market standards prior to advancing funds. The Company is repaid with the proceeds received from sale of the mortgage loan to the final investor.
Federal Home Loan Bank ("FHLB") Stock	Federal Home Loan Bank (“FHLB”) Stock The Company is a member of the FHLB system. Members of the FHLB are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB stock is carried at cost, are restricted as to redemption, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as income.
Premises and Equipment	Premises and Equipment Land is carried at cost. Depreciable assets are stated at cost less accumulated depreciation. Leasehold improvements are capitalized and depreciated using the straight-line method over the terms of the respective leases or the estimated useful lives of the improvements, whichever is shorter. Buildings and related components are generally depreciated using the straight-line method with useful lives ranging from thirty to forty years. Automobiles are depreciated using the straight-line method with five year useful lives, and the aircraft is depreciated using an accelerated method with a twenty year useful life. Furniture, fixtures and equipment are depreciated using the straight-line method with useful lives ranging from three to ten years.
Foreclosed Assets	Foreclosed Assets Assets acquired through loan foreclosure are initially recorded at fair value less costs to sell, establishing a new cost basis. Any write-down in the carrying value of a property at the time of acquisition is charged-off to the allowance for loan and lease losses. After foreclosure, foreclosed assets are carried at the lower of the recorded investment in the asset or the fair value less costs to sell. If fair value declines subsequent to foreclosure, a valuation allowance is recorded through expense. Operating costs after acquisition are expensed.
Goodwill	Goodwill Goodwill represents the excess of the cost of businesses acquired over the fair value of the net assets acquired. In accordance with ASC 350-20, "Intangibles- Goodwill and Other", the Company evaluates goodwill for impairment on an annual basis or on an interim basis if an event occurs or circumstances change that would more likely than not reduce the fair value below its carrying amount, in accordance with ASC 350-20. The Company’s annual goodwill impairment testing date is October 1. The Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining the need to perform the two-step test for goodwill impairment (the qualitative method). If the qualitative method cannot be used or if it determines, based on the qualitative method, that the fair value is more likely than not less than the carrying amount, the Company uses the two-step test. Under the two-step test, the Company compares the estimated fair value of a reporting unit with its carrying amount, including goodwill. If the estimated fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is considered not impaired. If the carrying amount of a reporting unit exceeds its estimated fair value, the second step of the goodwill impairment test is performed to measure the amount of impairment loss, if any. Step two of the goodwill impairment test compares the implied estimated fair value of reporting unit goodwill with the carrying amount of that goodwill. If the carrying amount of goodwill for that reporting unit exceeds the implied fair value of that unit’s goodwill, an impairment loss is recognized in an amount equal to that excess. Our annual goodwill impairment test did not identify any goodwill impairment for the years ended December 31, 2018 and 2017.
Identifiable Intangible Assets	Identifiable Intangible Assets Intangible assets are acquired assets that lack physical substance but can be distinguished from goodwill because of contractual or other legal rights or because the asset is capable of being sold or exchanged either on its own or in combination with a related contract, asset, or liability. The Company's intangible assets primarily relate to core deposits and customer relationships. Intangible assets with definite useful lives are amortized on an accelerated basis over their estimated life. Intangible assets, premises and equipment and other long-lived assets are tested for impairment whenever events or changes in circumstances indicate the carrying amount of the assets may not be recoverable from future undiscounted cash flows. If impaired, the assets are recorded at fair value with a charge to amortization of intangible assets.
Bank Owned Life Insurance	Bank Owned Life Insurance The Company has purchased life insurance policies on certain key employees. The purchase of these life insurance policies allows the Company to use tax-advantaged rates of return. Bank-owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement.
Income Taxes	Income Taxes The Company files a consolidated tax return with its subsidiaries and is taxed as a C corporation. Deferred tax assets and liabilities are reflected at currently enacted income tax rates applicable to the period in which the deferred tax assets and liabilities are expected to be realized or settled. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. The Company recognizes interest and penalties related to income tax matters in income tax expense.
Fair Values of Financial Instruments	Fair Values of Financial Instruments In general, fair values of financial instruments are based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based upon internally developed models that may use, as inputs, observable market-based parameters. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. These adjustments may include amounts to reflect counterparty credit quality and/or the Company’s creditworthiness, among other things, as well as unobservable parameters. Any such valuation adjustments are applied consistently over time. Changes in assumptions or in market conditions could significantly affect these estimates. In the ordinary course of business, the Company generally does not sell or transfer non-impaired loans and deposits. As such, the disclosures that present the December 31, 2018 and 2017 estimated fair value for non-impaired loans and deposits are highly judgmental and may not represent amounts to be received if the Company were to sell or transfer such items.
Revenue from Contracts with Customers	Revenue from Contracts with Customers The Company records revenue from contracts with customers in accordance with Accounting Standards Codification Topic 606, “Revenue from Contracts with Customers” (“Topic 606”). Under Topic 606, the Company must identify the contract with a customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract, and recognize revenue when (or as) the Company satisfies a performance obligation. Significant revenue has not been recognized in the current reporting period that results from performance obligations satisfied in previous periods. The Company’s primary sources of revenue are derived from interest and dividends earned on loans, investment securities, and other financial instruments that are not within the scope of Topic 606. The Company has evaluated the nature of its contracts with customers and determined that further disaggregation of revenue from contracts with customers into more granular categories beyond what is presented in the Consolidated Statements of Income was not necessary. The Company generally fully satisfies its performance obligations on its contracts with customers as services are rendered and the transaction prices are typically fixed; charged either on a periodic basis or based on activity. Because performance obligations are satisfied as services are rendered and the transaction prices are fixed, the Company has made no significant judgments in applying the revenue guidance prescribed in ASC 606 that affect the determination of the amount and timing of revenue from contracts with customers.
Asset Management Fees	Asset Management Fees On March 31, 2017, the Company sold its membership interests in TCA. At the date of sale, the Company ceased to provide fee based asset management services. Prior to the sale of TCA, asset management fee income was recognized through the Company’s collateralized loan obligation (“CLO”) asset management business operated by TCA and consisted of senior (or base) asset management fees, subordinated management fees, and performance-based incentive fees. Senior and subordinated management fees were based upon a fixed fee rate applied to the amount of outstanding assets being managed by TCA and were accrued by the Company as earned. Performance-based incentive fees were variable in nature and dependent upon the performance of a managed CLO above a prescribed level. The Company did not accrue for performance-based incentive fees that were not finalized until the end of a specified contract period, but recorded such revenues only when final payment was confirmed and related services were completed. The Company did not recognized any revenue that is at risk due to future asset management performance contingencies. TCA also entered into transactions whereby it earned asset management fee income through the provision of middle and back office services to other CLO asset managers.
Operating Segments	Operating Segments The Company’s reportable segments are comprised of strategic business units primarily based upon industry categories and to a lesser extent, the core competencies relating to product origination, distribution methods, operations and servicing. Segment determination also considered organizational structure and our segment reporting is consistent with the presentation of financial information to the chief operating decision maker to evaluate segment performance, develop strategy, and allocate resources. Our chief operating decision maker is the Chief Executive Officer of Triumph Bancorp, Inc. We have determined our reportable segments are Banking, Factoring, and Corporate. The banking segment includes the operations of TBK Bank. The banking segment derives its revenue principally from investments in interest earning assets as well as noninterest income typical for the banking industry. The banking segment also includes commercial factoring services which are originated through the commercial finance division of TBK Bank. The factoring segment includes the operations of TBC with revenue derived from factoring services. The corporate segment includes holding company financing and investment activities and management and administrative expenses to support the overall operations of the Company. On March 31, 2017, the Company sold its 100% membership interest in Triumph Capital Advisors, LLC and discontinued fee based asset management services. TCA operations for the years ended December 31, 2017 and 2016 are reflected in the Corporate segment, along with the gain on sale of the Company’s membership interest in TCA.
Comprehensive Income (Loss)	Comprehensive Income (Loss) Comprehensive income (loss) consists of net income and other comprehensive income (loss). Other comprehensive income includes unrealized gains and losses on debt securities available for sale, net of taxes, which are also recognized as a separate component of equity.
Loss Contingencies	Loss Contingencies Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Management does not believe such matters exist that will have a material effect on the financial statements.
Transfers of Financial Assets	Transfers of Financial Assets Transfers of financial assets are accounted for as sales when control over the assets has been relinquished. Control over transferred assets is deemed to be relinquished when (i) the assets have been isolated from the Company, (ii) the transferee has the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (iii) the Company does not maintain effective control over the transferred assets through either (a) an agreement that entitles and obligates the Company to repurchase or redeem them before their maturity or (b) the ability to unilaterally cause the holder to return specific assets.
Stock-Based Compensation	Stock Based Compensation Compensation cost is recognized for stock based payment awards issued to employees and directors, based on the fair value of these awards at the date of grant. A Black-Scholes model is utilized to estimate the fair value of stock options, a Monte Carlo simulation is utilized to estimate the fair value of performance stock units, and the market price of the Company’s common stock at the date of grant is used for restricted stock awards and restricted stock units. Compensation cost is recognized over the required service period, generally defined as the vesting period. The Company recognizes forfeitures of nonvested awards as they occur.
Earnings Per Common Share	Earnings Per Common Share Basic earnings per common share is net income less dividends on preferred stock divided by the weighted average number of common shares outstanding during the period excluding nonvested restricted stock awards. Diluted earnings per common share includes the dilutive effect of additional potential common shares issuable under stock warrants, restricted stock, stock options, and preferred shares that are convertible to common shares.
Advertising Costs	Advertising Costs Advertising costs are expensed as incurred.
Adoption of New Accounting Standards	Adoption of New Accounting Standards In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers” (“ASU 2014-09”), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU replaces most existing revenue recognition guidance in GAAP. The new standard was effective for the Company on January 1, 2018. Adoption of ASU 2014-09 did not have a material impact on the Company’s consolidated financial statements and related disclosures as the Company’s primary sources of revenues are derived from interest and dividends earned on loans, investment securities, and other financial instruments that are not within the scope of ASU 2014-09. The Company’s revenue recognition pattern for revenue streams within the scope of ASU 2014-09, including but not limited to service charges on deposit accounts and gains/losses on the sale of OREO, did not change significantly from current practice. The standard permits the use of either the full retrospective or modified retrospective transition method. The Company elected to use the modified retrospective transition method which requires application of ASU 2014-09 to uncompleted contracts at the date of adoption however, periods prior to the date of adoption will not be retrospectively revised as the impact of the ASU on uncompleted contracts at the date of adoption was not material. In January 2016, the FASB issued ASU No. 2016-01, “Financial Instruments – Overall: Recognition and Measurement of Financial Assets and Financial Liabilities” (“ASU 2016-01”). The guidance affects the accounting for equity investments, financial liabilities under the fair value option and the presentation and disclosure requirements of financial instruments. ASU 2016-01 was effective for the Company on January 1, 2018 and resulted in separate classification of equity securities previously included in available for sale securities on the consolidated balance sheets with changes in the fair value of the equity securities captured in the consolidated statements of income. See Note 3 – Securities for disclosures related to equity securities. Adoption of the standard also resulted in the use of an exit price rather than an entrance price to determine the fair value of loans not measured at fair value on a non-recurring basis in the consolidated balance sheets. See Note 15 – Fair Value Disclosures for further information regarding the valuation of these loans. In January 2017, the FASB issued ASU 2017-01, “Business Combinations (Topic 805): Clarifying the Definition of a Business,” (“ASU 2017-01”) to improve such definition and, as a result, assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or as business combinations. The definition of a business impacts many areas of accounting including acquisitions, disposals, goodwill and consolidation. ASU 2017-01 was effective for the Company on January 1, 2018 and is to be applied under a prospective approach. The Company expects the adoption of this new guidance to impact the determination of whether future acquisitions are considered business combinations or asset purchases.
Newly Issued, But Not Yet Effective Accounting Standards	Newly Issued, But Not Yet Effective Accounting Standards In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)” (“ASU 2016-02”). The FASB issued this ASU to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet by lessees for those leases classified as operating leases under current U.S. GAAP and disclosing key information about leasing arrangements. The 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 has elected to apply ASU 2016-02 as of the beginning of the period of adoption (January 1, 2019) and will not restate comparative periods. The Company expects that the adoption of ASU 2016-02 will result in the recognition of lease liabilities totaling $21,000,000 to $23,000,000 and the recognition of right-of-use assets totaling $21,000,000 to $23,000,000, which results in a 5- to 7-basis point decrease in the tier 1 capital to risk weighted assets ratio as of the date of adoption. The initial balance sheet gross up upon adoption is primarily related to operating leases of certain real estate properties. The Company has no material leasing arrangements for which it is the lessor of property or equipment. The Company has made an accounting policy election to not apply the recognition requirements in the new standard to short-term leases. 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 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. The Company has also elected to use the practical expedient to make an accounting policy election for leases of certain underlying assets to include both lease and nonlease components as a single component and account for it as a lease. Adoption of ASU 2016-02 is not expected to materially change the Company’s recognition of lease expense in future periods. 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.

On December 22, 2017, the United States enacted tax reform legislation commonly known as the Tax Cuts and Jobs Act (the “Tax Act”), resulting in significant modifications to existing law. As a result of the changes under the Tax Act, the Company recorded incremental income tax expense of $2,984,000 during the year ended December 31, 2017, which consisted primarily of the remeasurement of deferred tax assets and liabilities at the new federal statutory rate of 21%. Prior to the enactment of the Tax Act, deferred tax assets and liabilities were measured at the previous federal statutory rate of 35%.
