Accounting Policies [Abstract]
Significant Accounting Policies	Note 1 - Significant Accounting Policies Nature of Operations . Origin Bancorp, Inc. ("Company") is a financial holding company headquartered in Ruston, Louisiana. The Company's wholly owned bank subsidiary, Origin Bank ("Bank"), provides a broad range of financial services to businesses, municipalities, high net worth individuals and retail clients. The Company currently operates 43 banking centers located in North Louisiana, Central Mississippi, Dallas/Fort Worth and Houston, Texas. The Company principally operates in one business segment, community banking. Basis of Presentation . The consolidated financial statements include the accounts of the Company and all other entities in which Origin Bancorp, Inc. has a controlling financial interest, including the Bank and Davison Insurance Agency, LLC ("Davison Insurance"), doing business as Thomas & Farr Agency, and Reeves, Coon and Funderburg ("RCF"). All significant intercompany balances and transactions have been eliminated in consolidation. The Company's accounting and financial reporting policies conform, in all material respects, to accounting principles generally accepted in the United States ("U.S. GAAP") and to general practices within the financial services industry. The Company has evaluated subsequent events for potential recognition and/or disclosure through the date these consolidated financial statements were issued. Reclassifications . Certain amounts previously reported have been reclassified to conform to the current presentation. Such reclassifications had no effect on prior year net income or stockholders' equity. Variable Interest Entities . 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 ("VIE") under U.S. 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 all, or at least a majority of, the voting interest. As defined in applicable accounting standards, 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. The Company's wholly owned subsidiaries CTB Statutory Trust I and First Louisiana Statutory Trust I are VIEs for which the Company is not the primary beneficiary. Accordingly, the accounts of these trusts are not included in the Company's consolidated financial statements. Operating Segments . Operating segments are components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision-maker in deciding how to allocate resources and in assessing performance. The Bank is the only significant subsidiary upon which management makes decisions regarding how to allocate resources and assess performance. Individual bank branches offer a group of similar services, including commercial, real estate and consumer loans, time deposits, checking and savings accounts, all with similar operating and economic characteristics. While the chief operating decision-maker monitors the revenue streams of the various products and services, operations are managed and financial performance is evaluated on a Company-wide basis. Accordingly, all of the community banking services and branch locations are considered by management to be aggregated into one reportable operating segment, community banking. Use of Estimates . To prepare financial statements in conformity with U.S. 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. Material estimates that are subject to significant change in the near term are the allowance for loan losses, valuation of other real estate owned, fair value of mortgage servicing rights, realization of deferred tax assets, fair values of financial instruments and the status of contingencies. Actual results could differ from those estimates. Cash and Cash Equivalents . For purposes of the statement of cash flows, the Company considers all cash on hand, demand deposits with other banks, federal funds sold and short term interest-bearing cash items with an original maturity less than 90 days to be cash equivalents. The Company maintains deposits with other financial institutions in amounts that exceed federal deposit insurance coverage. Furthermore, federal funds sold are essentially uncollateralized loans to other financial institutions. Management regularly evaluates the credit risk associated with the counterparties to these transactions and believes that the Company is not exposed to any significant credit risks on cash and cash equivalents. At December 31, 2019 and 2018 the Company had cash collateral required to be held with counterparties on certain derivative transactions as discussed in Note 12 - Derivative Financial Instruments . At December 31, 2019 and 2018 the Company had no reserve requirement for cash balances with the Federal Reserve. Securities . The Company accounts for debt and equity securities as follows: Available for Sale ("AFS") - Debt and equity securities that will be held for indefinite periods of time, including securities that may be sold in response to changes in market interest or prepayment rates, needs for liquidity and changes in the availability of and the yield of alternative investments are classified as AFS. These assets are carried at fair value. Fair value is determined using published quotes. If quoted market prices are not available, fair values are based on other methods including, but not limited to the discounting of cash flows. Held to Maturity ("HTM") - Debt securities that management has the positive intent and ability to hold until maturity are classified as HTM and are carried at their remaining unpaid principal balance, net of unamortized premiums or unaccreted discounts. Securities Carried at Fair Value through Income - Debt securities for which the Company has elected the fair value option for accounting are classified as securities carried at fair value through income. Management has elected the fair value option for these items to offset the corresponding change in fair value of related interest rate swap agreements. Fair value is determined using discounted cash flows and credit quality indicators. Changes in fair value are reported through the consolidated statements of income as a part of other noninterest income. Unrealized gains and losses on AFS securities are excluded from earnings and reported net of tax in accumulated other comprehensive income until realized. Declines in the fair value of AFS and HTM securities below their cost are reflected in earnings as realized losses to the extent the impairment is deemed to be other-than-temporary credit losses. In estimating other-than-temporary impairment losses, management considers (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) management's intent and ability to retain the investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value. The amount of the impairment related to other factors is recognized in other comprehensive income unless there is no ability or intent to hold to recovery. Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities to the earlier of the call date or maturity date. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method. Non-marketable Equity Securities Held in Other Financial Institutions . Securities with limited marketability, such as stock in the Federal Reserve Bank of Dallas ("FRB") or the Federal Home Loan Bank of Dallas ("FHLB"), are carried at cost, less impairment, if any. These investments in stock do not have readily determinable fair values. The Company's remaining equity investments in other financial institutions, totaling $12.1 million and $11.7 million at December 31, 2019 and 2018 , respectively, qualify for the practicability exception under Accounting Standards Update ("ASU") 2016-01 due to having illiquid markets and are carried at cost, less impairment, plus or minus any observable price changes. The carrying value of these securities was evaluated and was determined not to be impaired for the years ended December 31, 2019 , 2018 and 2017 . Loans Held for Sale . Loans held for sale include mortgage loans and are carried at fair value, with unrealized gains and losses recorded in the consolidated statements of income. Forward commitments to sell mortgage loans are acquired to reduce market risk on mortgage loans in the process of origination and mortgage loans held for sale. The forward commitments acquired by the Company for mortgage loans in process of origination are mandatory forward commitments, and the Company is required to substitute another loan or to buy back the commitment if the original loan does not fund. Typically, the Company delivers the mortgage loans within a few days after the loans are funded. These commitments are derivative instruments carried at fair value. Gains and losses resulting from sales of mortgage loans are realized when the respective loans are sold to investors. Gains and losses are determined by the difference between the selling price (including the fair value of any items such as mortgage servicing rights) and the carrying amount of the loans sold. Fees received from borrowers to guarantee the funding of mortgage loans held for sale are recognized as income or expense when the loans are sold or when it becomes evident that the commitment will not be used. Loans . Loans that management has the intent and ability to hold for the foreseeable future, or until maturity or payoff, are reported at their outstanding unpaid principal balances adjusted for charge-offs, the allowance for loan losses, and any deferred fees or costs on originated loans. Interest income is accrued on the unpaid principal balance. Loan origination fees, and certain direct origination costs, are deferred and amortized as a yield adjustment over the lives of the related loans using the interest method. Late fees are recognized as income when earned, assuming collectability is reasonably assured. The Company has elected the fair value option on a small portion of its loans held for investment, with changes in fair value recorded in noninterest income. For these loans, the earned current contractual interest payment is recognized in interest income. Loan origination costs and fees are recognized in earnings as incurred and not deferred. Because these loans are recognized at fair value, the Company's allowance for loan losses policy does not apply to these loans. Fair value is determined using discounted cash flows and credit quality indicators. In addition to loans issued in the normal course of business, the Company considers overdrafts on customer deposit accounts to be loans and classifies these overdrafts as loans in its consolidated balance sheets. Loans are placed on nonaccrual status when management believes that the borrower's financial condition, after giving consideration to economic and business conditions and collection efforts, is such that collection of interest is doubtful, or generally when loans are 90 days or more past due. When accrual of interest is discontinued, all unpaid accrued interest is reversed. Past due status is based on contractual terms of the loan. Interest income on nonaccrual loans may be recognized to the extent cash payments are received, but payments received are usually applied to principal. Nonaccrual loans are generally returned to accrual status when principal and interest payments are less than 90 days past due, the customer has made required payments for at least six months, and the Company reasonably expects to collect all principal and interest. Allowance for Loan Losses . The allowance for loan losses is established as losses are estimated to have occurred through a provision for loan losses charged to earnings. The allowance for loan losses is evaluated on a regular basis by management and is based upon management's periodic review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower's ability to repay, estimated value of any underlying collateral, and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. Loans are charged off against the allowance for loan losses when management believes the loss is confirmed. Subsequent recoveries, if any, are credited to the allowance. The allowance consists of allocated and general components. The allocated component relates to loans that are classified as impaired, and an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan is lower than the carrying value of that loan. The general component relates to loans that are not classified as impaired and is based on historical charge-off experience and the expected loss, given default, derived from the Company's internal risk rating process. Other adjustments may be made to the allowance for pools of loans after an assessment of internal or external influences on credit quality that are not fully reflected in the historical loss or risk rating data. Delinquency statistics are updated at least monthly and are the most meaningful indicator of the credit quality of one-to-four single family residential, home equity loans and lines of credit and other consumer loans. Internal risk ratings are considered the most meaningful indicator of credit quality for commercial and industrial, construction, and commercial real estate loans. Internal risk ratings are a key factor in identifying loans that are individually evaluated for impairment and impact management's estimates of loss factors used in determining the amount of the allowance for loan losses. Internal risk ratings are updated on a regular basis. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Impaired loans include nonperforming loans and loans modified in troubled debt restructurings ("TDRs"). TDRs are loans for which the contractual terms on the loan have been modified and both of the following conditions exist: (1) the borrower is experiencing financial difficulty and (2) the restructuring constitutes a concession. Concessions could include a reduction in the interest rate on the loan, payment extensions, forgiveness of principal, forbearance or other actions intended to maximize collection. The Company assesses all loan modifications to determine whether they constitute a TDR. All TDRs are considered impaired loans. Impairment is measured on a loan-by-loan basis by either the present value of expected future cash flows discounted at the loan's effective interest rate, the loan's obtainable market price or the fair value of the collateral if the loan is collateral dependent. 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. Premises and Equipment, net . Land is carried at cost. Buildings and improvements are stated at cost less accumulated depreciation computed using the straight-line method over the estimated useful lives of the assets, which range from 35 to 39 years. Furniture, fixtures, and equipment are stated at cost less accumulated depreciation computed using the straight-line method over the estimated useful lives of the assets, which range from three to seven years . Leases. The Company adopted ASU No. 2016-02 — Leases (Topic 842) as of January 1, 2019, and recorded a $19.7 million right-of-use ("ROU") asset offset by a $19.4 million lease liability, recognizing a net after tax $321,000 cumulative effect adjustment credit to retained earnings. The Company elected the package of practical expedients, which among other things, does not require reassessment of lease classification. The Company determines if an arrangement is a lease at inception. Operating lease assets are included in accrued interest receivable and other assets, operating lease liabilities are included in accrued expenses and other liabilities in the Company's consolidated balance sheets. The Company has made an accounting policy election not to recognize short-term lease assets and liabilities (less than a 12-month term) or immaterial equipment and server space leases in its balance sheets; instead, the Company recognizes the lease expense for these leases on a straight-line basis over the life of the lease. The Company has no material finance leases. ROU assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. ROU lease assets and liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term. The Company uses an estimated incremental collateralized borrowing rate, which is derived from information available at the lease commencement date and gives consideration to the applicable FHLB borrowing rates, when determining the present value of lease payments. The Company's lease terms include options to extend a lease when it is reasonably certain that the Company will exercise that option. The Company's lease agreements do not contain any residual value guarantees. All of the Company's operating long-term leases are real estate leases, which are accounted for as a single lease component. Mortgage Servicing Rights and Transfers of Financial Assets . Gains or losses on "servicing-retained" loan sale transactions generally include a component reflecting the differential between the contractual interest rate of the loan and the interest rate to be received by the investor. The present value of the estimated future profit for servicing the loans is also taken into account in determining the amount of gain or loss on the sale of these loans. For loans sold servicing-retained, the fair value of mortgage servicing rights is recorded as an asset, with their value estimated using a discounted cash flow methodology to arrive at the present value of future expected earnings from the servicing of the loans. Significant model inputs include prepayment speeds, discount rates, and servicing costs. Servicing revenues are based on a contractual percentage of the outstanding principal or a fixed amount per loan and are recorded as income when earned. Loans sold into the secondary market are considered transfers of financial assets. These transfers are accounted for as sales when control over the asset has been surrendered, which is deemed to have occurred when: an asset does not have any claims to it by the transferor or their creditors, including in bankruptcy or other receivership situations; the transferee obtains the unconditional right to pledge or exchange the asset; or the transfer does not include a repurchase provision above the limited recourse provisions of these loan sales. Derivative Instruments and Hedging Activities . All derivatives are recorded on the accompanying consolidated balance sheets at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. During the term of a cash flow hedge contract the effective portion of changes in fair value in the derivative instrument are recorded in accumulated other comprehensive income. Changes in the fair value of derivatives to which hedge accounting does not apply are recognized immediately in earnings. Note 12 - Derivative Financial Instruments describes the derivative instruments currently used by the Company and discloses how these derivatives impact its consolidated balance sheets and statements of income. Goodwill and Other Intangible Assets . Goodwill, which represents the excess of cost over the fair value of the net assets of an acquired business, is not amortized but tested for impairment on an annual basis, which is October 1 for the Company, or more often if events or circumstances indicate that there may be impairment. Other intangible assets, such as relationship based intangibles and core deposit intangibles, are amortized on a basis consistent with the receipt of economic benefit to us. Such assets are evaluated at least annually as to the recoverability of their carrying value for potential impairment. In the quarter following the period in which identified intangible assets become fully amortized, the fully amortized balances are removed from the gross asset and accumulated amortization amounts. Other Real Estate Owned . Other real estate owned ("OREO") represents properties acquired through foreclosure or acceptance of a deed in lieu of foreclosure on loans on which the borrowers have defaulted as to payment of principal and interest. OREO also includes bank-owned real estate which the Company is no longer utilizing and intends to sell. These properties are initially recorded at fair value, less cost to sell, at the date of foreclosure establishing a new cost basis. Fair value is determined based on third party appraisals. Any subsequent capital improvements that increase value are added to the balance of the properties. Any valuation adjustments required at the date of transfer from loans to OREO are charged to the allowance for loan losses. Any subsequent write-downs to reflect current fair value, or gains and losses on the sale of the properties are charged to noninterest income. At December 31, 2019 and 2018 , the balance of OREO was $4.7 million and $3.7 million, respectively, and included as a component of other assets in the accompanying consolidated balance sheets. Overnight Repurchase Agreements with Depositors . The Company enters into agreements under which it sells securities subject to an obligation to repurchase the same or similar securities. Under these arrangements, the Company may transfer legal control over the assets but still retain effective control through an agreement that both entitles and obligates it to repurchase the assets. Securities sold under agreements to repurchase generally mature on the banking day following that on which the investment was initially sold and are treated as collateralized financing transactions which are recorded at the amounts at which the securities were sold plus accrued interest. Interest rates and maturity dates of the securities involved vary and are not intended to be matched with funds from customers. Mortgage Banking Revenue . This revenue category primarily reflects the Company's mortgage production, sales and mortgage servicing revenue, including fees and income derived from mortgages originated with the intent to sell; mortgage sales and servicing; and the impact of risk management activities associated with the mortgage pipeline and mortgage servicing rights ("MSRs"). This revenue category also includes gains and losses on sales and changes in fair value for mortgage loans originated with the intent to sell and measured at fair value under the fair value option. Changes in the fair value of MSRs are reported in mortgage banking revenue. Net interest income from mortgage loans is recorded in interest income. Income Taxes . Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax bases of assets and liabilities, computed using enacted tax rates. A valuation allowance, if needed, reduces 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 did not have any amount accrued with respect to uncertainty in income taxes at December 31, 2019 and 2018 . The Company recognizes interest and/or penalties related to income tax matters as a component of noninterest expense. There were no penalties or related interest for the years ended December 31, 2019, 2018 or 2017. Federal income tax expense or benefit has been allocated to subsidiaries on a separate return basis. Stock-Based Compensation . The cost of employee services received in exchange for stock options or restricted stock grants are measured using the fair value of the award on the grant date and is recognized over the service period. Other Investments . The Company accounts for investments in limited partnerships, limited liability companies ("LLCs"), and other privately held companies using either the equity method of accounting or at amortized cost net of impairments and observable price changes. The accounting treatment depends upon the Company's percentage ownership or degree of management influence. Under the equity method of accounting, the Company records its initial investment at cost. Subsequently, the carrying amount of the investment is increased or decreased to reflect its share of income or loss of the investee. The Company's recognition of earnings or losses from an equity method investment is based on its ownership percentage in the investee and the investee's earnings for the reporting period, and is recorded on a one-quarter lag. All of the Company's investments in limited partnerships, LLCs, and other companies are privately held, and their fair values are not readily available. Management evaluates the investments in investees for impairment based on the investee's ability to generate cash through its operations or obtain alternative financing, and other subjective factors. There are inherent risks associated with investments in such companies, which may result in volatility in the consolidated statements of income in future periods. At December 31, 2019 and 2018, investments in limited partnerships, LLCs and other privately held companies totaled $16.0 million and $14.5 million , respectively, and were included in other assets in the accompanying consolidated balance sheets. Investments in Tax Credit Entities . As part of its Community Reinvestment Act responsibilities and due to their favorable economic characteristics, the Company invests in tax credit-motivated projects primarily in the markets it serves. These projects are directed at tax credits issued under Low-Income Housing Tax Credits. The Company generates returns on tax credit motivated projects through the receipt of federal, and if applicable, state tax credits. The federal tax credits are recorded as an offset to the income tax provision in the year that they are earned under federal income tax law – over 10 to 15 years beginning in the year in which rental activity commences. These credits, if not used in the tax return for the year of origination, can be carried forward for 20 years. The Company invests in a tax credit entity, usually an LLC, which owns the real estate. The Company receives a nonvoting interest in the entity that must be retained during the compliance period for the credits ( 15 years for Low-Income Housing Tax Credit programs). Control of the tax credit entity rests in the 0.1% interest general partner, who has the power and authority to make decisions that impact economic performance of the project and is required to oversee and manage the project. Due to the lack of any voting, economic, or managerial control, and due to the contractual reduction in the investment, the Company accounts for its investment by amortizing the investment, beginning at the issuance of the certificate of occupancy of the project, over the compliance period, as management believes any potential residual value in the real estate will have limited value. Amortization is included as a component of income tax expense. The Company has the risk of credit recapture if the project does not maintain compliance during the compliance period. No such events have occurred to date. At December 31, 2019 and 2018, the Company had investments in tax credit entities of $9.0 million and $10.6 million , respectively, which are included in other assets in the accompanying consolidated balance sheets. Earnings Per Share . Basic and diluted earnings per common share for periods beginning after December 31, 2018, are calculated using the treasury method. Under the treasury method, basic earnings per share is calculated as net income divided by the weighted average number of common shares outstanding during the period. Diluted earnings per share includes the dilutive effect of additional potential common shares issuable under stock options and restricted stock awards. Basic and diluted earnings per common share for periods ending on or before December 31, 2018, were calculated using the two-class method. The two-class method is an earnings allocation formula that determines earnings per share for each share of common stock and participating securities according to dividends declared (distributed earnings) and participation rights in undistributed earnings. Distributed and undistributed earnings were allocated between common and participating security stockholders based on their respective rights to receive dividends. Share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents were considered participating securities (e.g., restricted stock grants). Preferred stock that receives dividends based on dividends paid on common stock was also considered a participating security (e.g., Series D preferred stock). Net income attributable to common stockholders was then divid

Such shares or units are considered participating securities (i.e., nonvested restricted stock grants). Additionally, for period prior to June 30, 2018, Series D preferred stockholders were participating stockholders as those shares participate in dividends with common shares on a one for one basis. Net income allocated to participating stockholders does not include dividends paid to preferred stockholders. (2) The average participating share count for the calculation of earnings per share for the year ended December 31, 2018, includes an allocation for Series D preferred stockholders, which were converted to common stock during the quarter ended June 30, 2018.

The unrealized losses for each of the securities relate to market interest rate changes. The Company has considered the current market for the securities in an unrealized loss position, as well as the severity and duration of the impairments, and expects that the value will recover. Management does not intend to sell these investments until the fair value exceeds amortized cost and it is more likely than not that the Company will not be required to sell debt securities before the anticipated recovery of the amortized cost basis of the security; thus, the impairment is determined not to be other-than-temporary. Proceeds from sales of securities available for sale and gross gains for the years ended December 31, 2019 and 2018 . There were no security sales during the year ended December 31, 2017.

Included in total loans held for investment were $17.7 million and $18.6 million of commercial real estate loans for which the fair value option was elected as of December 31, 2019 and 2018, respectively. The Company mitigates the interest rate component of fair value risk on loans at fair value by entering into derivative interest rate contracts. See Note 5 - Fair Value of Financial Instruments for more information on loans for which the fair value option has been elected. Credit quality indicators. As part of the Company's commitment to manage the credit quality of its loan portfolio, management annually updates and evaluates certain credit quality indicators, which include but are not limited to (i) weighted-average risk rating of the loan portfolio, (ii) net charge-offs, (iii) level of non-performing loans, (iv) level of classified loans, and (v) the general economic conditions in the states in which the Company operates. The Company maintains an internal risk rating system where ratings are assigned to individual loans based on assessed risk. Loan risk ratings are the primary indicator of credit quality for the loan portfolio and are continually evaluated to ensure they are appropriate based on currently available information. The following is a summary description of the Company's internal risk ratings: • Pass (1-6) Loans within this risk rating are further categorized as follows: Minimal risk (1) Well-collateralized by cash equivalent instruments held by the Bank. Moderate risk (2) Borrowers with excellent asset quality and liquidity. Borrowers' capitalization and liquidity exceed industry norms. Borrowers in this category have significant levels of liquid assets and have a low level of leverage. Better than average risk (3) Borrowers with strong financial strength and excellent liquidity that consistently demonstrate strong operating performance. Borrowers in this category generally have a sizable net worth that can be converted into liquid assets within 12 months. Average risk (4) Borrowers with sound credit quality and financial performance, including liquidity. Borrowers are supported by sufficient cash flow coverage generated through operations across the full business cycle. Marginally acceptable risk (5) Loans generally meet minimum requirements for an acceptable loan in accordance with lending policy, but possess one or more attributes that cause the overall risk profile to be higher than the majority of newly approved loans. Watch (6) A passing loan with one or more factors that identify a potential weakness in the overall ability of the borrower to repay the loan. These weaknesses are generally mitigated by other factors that reduce the risk of delinquency or loss. • Special Mention (7) This grade is intended to be temporary and includes borrowers whose credit quality have deteriorated and is at risk of further decline. • Substandard (8) This grade includes "Substandard" loans under regulatory guidelines. Substandard loans exhibit a well-defined weakness that jeopardizes debt repayment in accordance with contractual agreements, even though the loan may be performing. These obligations are characterized by the distinct possibility that a loss may be incurred if these weaknesses are not corrected and repayment may be dependent upon collateral liquidation or secondary source of repayment. • Doubtful (9) This grade includes "Doubtful" loans under regulatory guidelines. Such loans are placed on nonaccrual status and repayment may be dependent upon collateral with no readily determinable valuation or valuations that are highly subjective in nature. Repayment for these loans is considered improbable based on currently existing facts and circumstances. • Loss (0) This grade includes "Loss" loans under regulatory guidelines. Loss loans are charged-off or written down when repayment is not expected. Loans held for investment by credit quality indicator at December 31, 2019 and 2018 , were as follows: (Dollars in thousands) December 31, 2019 Loans secured by real estate: Pass Special Mention Substandard Doubtful Loss Total Commercial real estate $ 1,269,493 $ 12,479 $ 14,875 $ — $ — $ 1,296,847 Construction/land/land development 512,901 149 4,638 — — 517,688 Residential real estate 680,046 1,558 7,951 — — 689,555 Total real estate 2,462,440 14,186 27,464 — — 2,504,090 Commercial and industrial 1,277,564 28,478 37,433 — — 1,343,475 Mortgage warehouse lines of credit 274,659 — — — — 274,659 Consumer 20,808 — 163 — — 20,971 Total loans held for investment $ 4,035,471 $ 42,664 $ 65,060 $ — $ — $ 4,143,195 (Dollars in thousands) December 31, 2018 Loans secured by real estate: Pass Special Mention Substandard Doubtful Loss Total Commercial real estate $ 1,206,194 $ 3,101 $ 19,107 $ — $ — $ 1,228,402 Construction/land/land development 426,770 157 2,733 — — 429,660 Residential real estate 617,996 1,142 10,576 — — 629,714 Total real estate 2,250,960 4,400 32,416 — — 2,287,776 Commercial and industrial 1,190,718 34,964 46,884 — — 1,272,566 Mortgage warehouse lines of credit 207,871 — — — — 207,871 Consumer 20,712 — 180 — — 20,892 Total loans held for investment $ 3,670,261 $ 39,364 $ 79,480 $ — $ — $ 3,789,105 The following tables present the Company's loan portfolio aging analysis at the dates indicated: (Dollars in thousands) December 31, 2019 Loans secured by real estate: 30-59 Days Past Due 60-89 Days Past Due Loans Past Due 90 Days or More Total Past Due Current Loans Total Loans Receivable Accruing Loans 90 or More Days Past Due Commercial real estate $ 917 $ — $ 5,891 $ 6,808 $ 1,290,039 $ 1,296,847 $ — Construction/land/land development 3,569 133 56 3,758 513,930 517,688 — Residential real estate 2,174 1,918 913 5,005 684,550 689,555 — Total real estate 6,660 2,051 6,860 15,571 2,488,519 2,504,090 — Commercial and industrial 1,588 1,037 11,545 14,170 1,329,305 1,343,475 — Mortgage warehouse lines of credit — — — — 274,659 274,659 — Consumer 164 35 40 239 20,732 20,971 — Total loans held for investment $ 8,412 $ 3,123 $ 18,445 $ 29,980 $ 4,113,215 $ 4,143,195 $ — (Dollars in thousands) December 31, 2018 Loans secured by real estate: 30-59 Days Past Due 60-89 Days Past Due Loans Past Due 90 Days or More Total Past Due Current Loans Total Loans Receivable Accruing Loans 90 or More Days Past Due Commercial real estate $ 458 $ 1,409 $ 7,224 $ 9,091 $ 1,219,311 $ 1,228,402 $ — Construction/land/land development 2,657 — 435 3,092 426,568 429,660 — Residential real estate 2,137 527 4,149 6,813 622,901 629,714 — Total real estate 5,252 1,936 11,808 18,996 2,268,780 2,287,776 — Commercial and industrial 276 8,263 6,157 14,696 1,257,870 1,272,566 — Mortgage warehouse lines of credit — — — — 207,871 207,871 — Consumer 383 8 2 393 20,499 20,892 — Total loans held for investment $ 5,911 $ 10,207 $ 17,967 $ 34,085 $ 3,755,020 $ 3,789,105 $ — The following tables detail activity in the allowance for loan losses by portfolio segment.

During the year ended December 31, 2018 , no loans defaulted after having been modified as a TDR within the previous 12 months. During the year ended December 31, 2017 , one loan with an outstanding principal balance of $241,000 defaulted after having been modified as a TDR within the previous 12 months. A payment default is defined as a loan that was 90 or more days past due. The modifications made during the year ended December 31, 2019, did not significantly impact the Company's determination of the allowance for loan losses. The Company monitors the performance of the modified loans to their restructured terms on an ongoing basis. In the event of a subsequent default, the allowance for loan losses continues to be reassessed on the basis of an individual evaluation of each loan.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Note 5 - Fair Value of Financial Instruments Fair value is the exchange price that is expected to 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. Certain assets and liabilities are recorded in the Company's consolidated financial statements at fair value. Some are recorded on a recurring basis and some on a non-recurring basis. The Company utilizes fair value measurement to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The determination of fair values of financial instruments often requires the use of estimates. In cases where quoted market values in an active market are not available, the Company utilizes valuation techniques that are consistent with the market approach, the income approach and/or the cost approach to estimate the fair values of its financial instruments. Such valuation techniques are consistently applied. A hierarchy for fair value has been established which categorizes the valuation techniques into three levels used to measure fair value. The three levels are as follows: Level 1 - Fair value is based on unadjusted quoted prices in active markets for identical assets or liabilities. Level 2 - Fair value is based on significant other observable inputs that are generally determined based on a single price for each financial instrument provided to the Company by an unrelated third-party pricing service and is based on one or more of the following: • Quoted prices for similar, but not identical, assets or liabilities in active markets; • Quoted prices for identical or similar assets or liabilities in markets that are not active; • Inputs other than quoted prices that are observable, such as interest rate and yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates; • Other inputs derived from or corroborated by observable market inputs. Level 3 - Prices or valuation techniques that require inputs that are both significant and unobservable in the market. These instruments are valued using the best information available, some of which is internally developed, and reflects the Company's own assumptions about the risk premiums that market participants would generally require and the assumptions they would use. There were no transfers between fair value reporting levels for any period presented.

The following methodologies were used to measure the fair value of financial assets and liabilities valued on a recurring basis: Securities Available for Sale Securities classified as available for sale are reported at fair value utilizing Level 1, Level 2 or Level 3 inputs. For Level 2 securities, the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, market consensus prepayment speeds, credit information and the security's terms and conditions, among other things. In order to ensure the fair values are consistent with Accounting Standards Codification ("ASC") 820, Fair Value Measurements and Disclosures , the Company periodically checks the fair value by comparing them to another pricing source, such as Bloomberg LP. The third-party pricing service is subject to an annual review of internal controls in accordance with the Statement on Standards for Attestation Engagements No. 16, which was made available to the Company. In certain cases where Level 2 inputs are not available, securities are classified within Level 3 of the hierarchy. Mortgage Servicing Rights ("MSR") The carrying amounts of the MSRs equal fair value and are valued using a discounted cash flow valuation technique. The significant assumptions used to value MSRs were as follows: December 31, 2019 2018 Prepayment speed 12.46 % 9.90 % Discount rate 9.55 10.42 In recent years, there have been significant market-driven fluctuations in the assumptions listed above. These fluctuations can be rapid and may continue to be significant. Therefore, estimating these assumptions within ranges that market participants would use in determining the fair value of MSRs requires significant management judgment. Derivatives Fair values for interest rate swap agreements are based upon the amounts that would be required to settle the contracts. Fair values for derivative loan commitments and forward loan sale commitments are based on fair values of the underlying mortgage loans and the probability of such commitments being exercised. Significant management judgment and estimation is required in determining these fair value measurements. Fair Values of Assets Recorded on a Recurring Basis for which the Fair Value Option has been Elected Certain assets are measured at fair value on a recurring basis due to the Company's election to adopt fair value accounting treatment for those assets. This election allows for a more effective offset of the changes in fair values of the assets and the derivative instruments used to economically hedge them without the burden of complying with the requirements for hedge accounting under ASC 815, Derivatives and Hedging. For assets for which the fair value has been elected, the earned current contractual interest payment is recognized in interest income, loan origination costs and fees on fair value option loans are recognized in earnings as incurred and not deferred. At December 31, 2019 and 2018, there were no gains or losses recorded attributable to changes in instrument-specific credit risk. The following tables summarize the difference between the fair value and the unpaid principal balance for financial instruments for which the fair value option has been elected: December 31, 2019 (Dollars in thousands) Aggregate Fair Value Aggregate Unpaid Principal Balance Difference Loans held for sale (1) $ 36,977 $ 36,037 $ 940 Commercial real estate loans held for investment (2) 17,670 17,366 304 Securities carried at fair value through income 11,513 11,070 443 Total $ 66,160 $ 64,473 $ 1,687 ____________________________ (1) A total of $927,000 of loans held for sale were designated as nonaccrual or 90 days or more past due at December 31, 2019 . Of this balance, the Company had guarantees receivable from U.S. Government agencies totaling $709,000 . (2) There were no commercial real estate loans for which the fair value had been elected that were designated as nonaccrual or 90 days or more past due at December 31, 2019 .

Of this balance, the Company had guarantees receivable from U.S. government agencies totaling $582,000 . (2) There were no commercial real estate loans for which the fair value had been elected that were designated as nonaccrual or 90 days or more past due at December 31, 2018 . Changes in the fair value of assets for which the Company elected the fair value option are classified in the consolidated statement of income line items reflected in the following table: (Dollars in thousands) Years Ended December 31, Changes in fair value included in noninterest income: 2019 2018 2017 Mortgage banking revenue $ 550 $ (163 ) $ 477 Other income: Loans at fair value held for investment 124 (389 ) (712 ) Securities carried at fair value through income 586 (258 ) (97 ) Total impact on other income 710 (647 ) (809 ) Total fair value option impact on noninterest income (1) $ 1,260 $ (810 ) $ (332 ) ____________________________ (1) The fair value option impact on noninterest income is offset by the derivative gain/loss recognized in noninterest income. Please see Note 9 - Mortgage Banking for more detail. The following methodologies were used to measure the fair value of financial assets valued on a recurring basis for which the fair value option was elected: Securities at Fair Value through Income Securities carried at fair value through income are valued using a discounted cash flow with a credit spread applied to each instrument based on the credit worthiness of each issuer. Credit spreads ranged from 83 to 227 basis points at both December 31, 2019 and 2018. The Company believes the fair value approximates an exit price. Loans Held for Sale Fair values for loans held for sale are established using anticipated sale prices for loans allocated to a sale commitment, and those unallocated to a commitment are valued based on the interest rate and term for similar loans allocated. The Company believes the fair value approximates an exit price. Loans Held for Investment For loans held for investment for which the fair value option has been elected, fair values are calculated using a discounted cash flow model with inputs including observable interest rate curves and unobservable credit adjustment spreads based on credit risk inherent in the loan. Credit spreads ranged from 290 to 413 basis points at December 31, 2019 , and ranged from 290 to 413 basis points at December 31, 2018 . The Company believes the fair value approximates an exit price. Fair Value of Assets Recorded on a Nonrecurring Basis Equity Securities without Readily Determinable Fair Values Equity securities without readily determinable fair values totaled $39.8 million at December 31, 2019 , and are shown on the face of the consolidated balance sheets. The majority of the Company's equity investments qualify for the practical expedient allowed for equity securities without a readily determinable fair value, such that the Company has elected to carry these securities at cost adjusted for any observable transactions during the period, less any impairment. To date, no impairment has been recorded on the Company's investments in equity securities that do not have readily determinable fair values. Government National Mortgage Association Repurchase Asset The Company recorded $27.9 million and $30.6 million , respectively, at December 31, 2019 and 2018, for Government National Mortgage Association ("GNMA") repurchase assets included in mortgage loans held for sale on the consolidated balance sheets. The assets are valued at the lower of cost or market and, where market is lower than cost, valued using anticipated sale prices for loans allocated to a sale commitment, and those unallocated to a commitment are valued based on the interest rate and term for similar loans allocated. The Company believes the fair value approximates an exit price. Please see Note 9 - Mortgage Banking for more information on the GNMA repurchase asset. Collateral Dependent Impaired Loans Loans for which it is probable that the Company will not collect all principal and interest due according to contractual terms are measured for impairment. Allowable methods for determining the amount of impairment include estimating fair value using the fair value of the collateral for collateral-dependent loans. If the impaired loan is identified as collateral-dependent, the fair value method of measuring the amount of impairment is utilized. This method requires obtaining a current independent appraisal of the collateral and applying a discount factor to the value. Impaired loans that are collateral-dependent are classified within Level 3 of the fair value hierarchy when impairment is determined using the fair value method. The fair value of impaired loans with specific allocated losses was $1.9 million and $1.4 million at December 31, 2019 and 2018, respectively. Non-Financial Assets Foreclosed assets held for sale are the only non-financial assets valued on a non-recurring basis that are initially recorded by the Company at fair value, less estimated costs to sell. At foreclosure, if the fair value, less estimated costs to sell, of the real estate acquired is less than the Company's recorded investment in the related loan, a write-down is recognized through a charge to the allowance for loan losses. Additionally, valuations are periodically performed by management and any subsequent reduction in value is recognized by a charge to income. The carrying value and fair value of foreclosed assets held for sale is estimated using Level 3 inputs based on observable market data and was $4.7 million and $3.7 million at December 31, 2019 and 2018, respectively. At December 31, 2019 , the Company had $786,000 in residential mortgage loans in the process of foreclosure. Fair Values of Financial Instruments Not Recorded at Fair Value The carrying value and estimated fair values of financial instruments not recorded at fair value are as follows: (Dollars in thousands) December 31, Financial assets: 2019 2018 Level 1 inputs: Carrying Estimated Carrying Value Estimated Fair Value Cash and cash equivalents $ 291,518 $ 291,518 $ 116,678 $ 116,678 Level 2 inputs: Non-marketable equity securities held in other financial institutions 39,808 39,808 42,149 42,149 Accrued interest and loan fees receivable 16,430 16,430 16,454 16,454 Level 3 inputs: Securities held to maturity 28,620 29,523 19,169 19,136 Loans held for investment, net (1) 4,088,005 3,940,347 3,736,331 3,605,142 Financial liabilities: Level 2 inputs: Deposits 4,228,612 4,081,430 3,783,138 3,537,283 FHLB advances and other borrowings 417,190 425,318 445,224 444,286 Junior subordinated debentures 9,671 10,717 9,644 10,723 Accrued interest payable 2,822 2,822 2,679 2,679 ____________________________ (1) Loans held for investment, net does not include loans for which the fair value option had been elected at December 31, 2019 or 2018, as these loans are carried at fair value on a recurring basis.

Management uses mortgage-backed securities to mitigate the impact of changes in fair value of MSRs. See Note 12 - Derivative Financial Instruments for further information. Mortgage Servicing Rights Activity in MSRs was as follows: Years Ended December 31, (Dollars in thousands) 2019 2018 2017 Balance at beginning of period $ 25,114 $ 24,182 $ 29,385 Origination of servicing rights 2,595 1,895 3,061 Change in fair value, including amortization, net (7,012 ) (963 ) (6,014 ) Sale of servicing rights — — (2,250 ) Balance at end of period $ 20,697 $ 25,114 $ 24,182 The Company receives annual servicing fee income approximating 0.28% of the outstanding balance of the underlying loans. In connection with the Company's activities as a servicer of mortgage loans, the investors and the securitization trusts have no recourse to the Company's assets for failure of debtors to pay when due. The Company is potentially subject to losses in its loan servicing portfolio due to loan foreclosures. The Company has obligations to either repurchase the outstanding principal balance of a loan or make the purchaser whole for the economic benefits of a loan if it is determined that the loan sold was in violation of representations or warranties made by it at the time of the sale, which the Company refers to as mortgage loan servicing putback expenses. Such representations and warranties typically include those made regarding loans that had missing or insufficient file documentation and/or loans obtained through fraud by borrowers or other third parties. Putback claims may be made until the loan is paid in full. When a putback claim is received, the Company evaluates the claim and takes appropriate actions based on the nature of the claim. The Company is required by Federal National Mortgage Association and Federal Home Loan Mortgage Corporation to provide a response to putback claims within 60 days of the date of receipt. The Company incurred $33,000 in mortgage loan servicing putback expense for the year ended December 31, 2019, and $106,000 for the year ended December 31, 2017. The Company incurred no mortgage loan servicing putback expense for the year ended December 31, 2018. At December 31, 2019 and 2018, the reserve for mortgage loan servicing putback expenses totaled $229,000 and $196,000 , respectively. There is inherent uncertainty in reasonably estimating the requirement for reserves against future mortgage loan servicing putback expenses. Future putback expenses depend on many subjective factors, including the review procedures of the purchasers and the potential refinance activity on loans sold with servicing released and the subsequent consequences under the representations and warranties. GNMA optional repurchase programs allow financial institutions to buy back individual delinquent mortgage loans that meet certain criteria from the securitized loan pool for which the institution provides servicing. At the servicer's option and without GNMA's prior authorization, the servicer may repurchase a delinquent loan for an amount equal to 100% of the remaining principal balance of the loan. This buy-back option is considered a conditional option until the delinquency criteria are met, at which time the option becomes unconditional. When the Company is deemed to have regained effective control over these loans under the unconditional buy-back option, the loans can no longer be reported as sold and must be included in the balance sheet as mortgage loans held for sale, regardless of whether the Company intends to exercise the buy-back option. These loans totaling $27.9 million and $30.6 million at December 31, 2019 and 2018, respectively, were reported as held for sale at lower of cost or market and included in mortgage loans held for sale and FHLB advances and other borrowings in the consolidated financial statements.

(2) Includes a FHLB advance of $250.0 million at both December 31, 2019 and 2018, callable quarterly with a final maturity in 2033, carrying a rate of 1.65% . Short-Term Borrowings As of December 31, 2019 and 2018 , the Company had unsecured lines of credit for the purchase of federal funds in the amount of $180.0 million as of December 31, 2019 and 2018. The Company also had a $75.0 million secured repurchase line of credit as of December 31, 2019. There were no amounts outstanding on these lines at either date. It is customary for the financial institutions granting the unsecured lines of credit to require a minimum amount of cash be held on deposit at that institution. Amounts required to be held on deposit are typically $250,000 or less, and the Company has complied with all compensating balance requirements to allow utilization of these lines of credit. Securities sold under agreements to repurchase consist of the Company's obligations to other parties and mature on a daily basis. These obligations to other parties carried a daily average interest rate of 1.20% and 0.86% for the years ended December 31, 2019 and 2018 , respectively. Long-Term Borrowings Interest rates for FHLB long-term advances outstanding at December 31, 2019 , ranged from 1.65% to 5.72% , and at December 31, 2018 , ranged from 1.65% to 5.72% . These advances are all fixed rate and are subject to restrictions or penalties in the event of prepayment. Scheduled maturities of long-term advances from the FHLB at December 31, 2019 , are as follows: (Dollars in thousands) Years Ended December 31, 2020 $ 1,070 2021 1,117 2022 2,479 2023 4,253 2024 3,142 Thereafter (1) 260,552 Total $ 272,613 __________________________ (1) Includes a FHLB advances totaling $250.0 million callable quarterly with a final maturity in 2033, carrying a rate of 1.65% . Security for all indebtedness and outstanding commitments to the FHLB consists of a blanket floating lien on all of the Company's first mortgage loans, commercial real estate and other real estate loans, as well as the Company's investment in capital stock of the FHLB and deposit accounts at the FHLB. The net amounts available under the blanket floating lien as of December 31, 2019 and 2018 , were $601.9 million and $468.8 million , respectively. Additionally, as of December 31, 2019 and December 31, 2018, the Company had the availability to borrow $855.1 million and $795.5 million , respectively, from the discount window at the Federal Reserve Bank of Dallas, with $1.09 billion and $1.05 billion in commercial and industrial loans pledged as collateral, respectively. There were no borrowings against this line as of December 31, 2019 or 2018. Holding Company Line of Credit During 2018, the Company entered into a Loan Agreement (the "Loan Agreement") with NexBank SSB ("Lender") pursuant to which the Lender will make one or more revolving credit loans of up to $50 million at any time that the Company may use for working capital and general corporate purposes. The principal amounts borrowed under the Loan Agreement will bear interest at a variable rate equal to the applicable one-month LIBOR rate plus 3.25% . The line of credit available to the Company under the Loan Agreement expires on October 5, 2021, or such date of the acceleration of the obligation pursuant to the Loan Agreement, at which time all amounts borrowed, together with applicable interest, fees and other amounts owed by the Company shall be due and payable. There were no outstanding revolving credit loans under the Loan Agreement as of December 31, 2019 or 2018. In connection with the entry into the Loan Agreement, the Company issued the Lender a Revolving Promissory Note dated October 5, 2018 (the "Note") in a principal amount of up to $50 million . The Company's obligations under the Loan Agreement and the Note are secured by a pledge of all of the issued and outstanding shares of Origin Bank (such shares, the "Collateral"), pursuant to the Pledge and Security Agreement, dated October 5, 2018 (the "Pledge Agreement"). The Loan Agreement, Note and the Pledge Agreement contain customary representations, warranties and covenants, including covenants requiring the Company and Origin Bank to maintain certain financial and capital ratios. The Loan Agreement, Note and the Pledge Agreement also provide for certain events of default, the occurrence of which, after any applicable cure period, would permit the Lender, among other things, to accelerate payment of all amounts outstanding under the Loan Agreement and the Note, as applicable, and to exercise its remedies with respect to the Collateral, including the sale of the Collateral. Junior Subordinated Debentures The Company has two wholly-owned, unconsolidated subsidiary grantor trusts that were established for the purpose of issuing trust preferred securities. The trust preferred securities accrue and pay distributions periodically at specified annual rates as provided in each trust agreement. The trusts used the net proceeds from each of the offerings to purchase a like amount of junior subordinated debentures (the "debentures") of the Company. The debentures are the sole assets of the trusts. The Company's obligations under the debentures and related documents, taken together, constitute a full and unconditional guarantee by the Company of the obligations of the trusts. The trust preferred securities are mandatorily redeemable upon maturity of the debentures, or upon earlier redemption as provided in the respective indentures. The Company has the right to redeem the debentures, in whole or in part on or after specific dates, at a redemption price specified in the indentures governing the debentures plus any accrued but unpaid interest to the redemption date. Due to the extended maturity date of the trust preferred securities, they are included in Tier I capital for regulatory purposes, subject to certain limitations. The following table is a summary of the terms of the current debentures at December 31, 2019 : (Dollars in thousands) Issuance Trust Issuance Date Maturity Date Amount Outstanding Rate Type Current Rate Maximum Rate CTB Statutory Trust I 07/2001 07/2031 $ 6,702 Variable (1) 5.23 % 12.50 % First Louisiana Statutory Trust I 09/2006 12/2036 4,124 Variable (2) 3.69 16.00 $ 10,826 ____________________________ (1) The trust preferred securities reprice quarterly based on the three-month LIBOR plus 3.30% , with the last reprice date on October 29, 2019. (2) The trust preferred securities reprice quarterly based on the three-month LIBOR plus 1.80% , with the last reprice date on December 12, 2019. The balance of the debentures outstanding varies from the amounts carried on the consolidated balance sheets due to the remaining purchase discount of $1.2 million at both December 31, 2019 and 2018 , which was established with the acquisition of the issuer of the First Louisiana Statutory Trust I securities, and which is being amortized over the remaining life of the securities using the interest method.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Note 12 - Derivative Financial Instruments Risk Management Objective of Using Derivatives The Company enters into derivative financial instruments to manage risks related to differences in the amount, timing, and duration of the Company's known or expected cash receipts and its known or expected cash payments, as well as to manage changes in fair values of some assets which are marked at fair value through the consolidated statement of income on a recurring basis. Cash Flow Hedges of Interest Rate Risk The Company is a party to an interest rate swap agreement under which the Company receives interest at a variable rate and pays at a fixed rate. The derivative instrument represented by this swap agreement is designated as a cash flow hedge of the Company's forecasted variable cash flows under a variable-rate term borrowing agreement. During the term of the swap agreement, the effective portion of changes in the fair value of the derivative instrument are recorded in accumulated other comprehensive income and subsequently reclassified into earnings in the periods that the hedged forecasted variable-rate interest payments affected earnings. There was no ineffective portion of the change in fair value of the derivative recognized directly in earnings. The entire swap fair value will be reclassified into earnings before the expiration date of the swap agreement. Derivatives Not Designated as Hedges Customer interest rate derivative program The Company offers certain derivatives products, primarily interest rate swaps, directly to qualified commercial banking customers to facilitate their risk management strategies. In some instances, the Company acts only as an intermediary, simultaneously entering into offsetting agreements with unrelated financial institutions, thereby mitigating its net risk exposure resulting from such transactions without significantly impacting its results of operations. Because the interest rate derivatives associated with this program do not meet hedge accounting requirements, changes in the fair value of both the customer derivatives and any offsetting derivatives are recognized directly in earnings as a component of noninterest income. Mortgage banking derivatives The Company enters into certain derivative agreements as part of its mortgage banking and related risk management activities. These agreements include interest rate lock commitments on prospective residential mortgage loans and forward commitments to sell these loans to investors on a mandatory delivery basis. The Company also economically hedges the value of MSRs by entering into a series of commitments to purchase mortgage-backed securities in the future. Fair Values of Derivative Instruments on the Balance Sheet The following tables disclose the fair value of derivative instruments in the Company's balance sheets at December 31, 2019 , 2018 and 2017 , as well as the effect of these derivative instruments on the Company's consolidated statements of income for the years ended December 31, 2019 and 2018 : Notional Amounts (1) Fair Values (Dollars in thousands) December 31, December 31, Derivatives designated as cash flow hedging instruments: 2019 2018 2019 2018 Interest rate swaps included in other (liabilities) assets $ 10,500 $ 10,500 $ (101 ) $ 152 Derivatives not designated as hedging instruments: Interest rate swaps included in other assets $ 217,633 $ 127,512 $ 8,425 $ 2,302 Interest rate swaps included in other liabilities 246,397 145,857 (9,278 ) (2,625 ) Forward commitments to purchase mortgage-backed securities included in other assets 200,000 140,000 242 709 Forward commitments to sell residential mortgage loans included in other liabilities 60,600 24,750 (109 ) (221 ) Interest rate-lock commitments on residential mortgage loans included in other assets 37,382 16,244 717 400 $ 762,012 $ 454,363 $ (3 ) $ 565 ____________________________ (1) Notional or contractual amounts, which represent the extent of involvement in the derivatives market, are used to determine the contractual cash flows required in accordance with the terms of the agreement. These amounts are typically not exchanged, significantly exceed amounts subject to credit or market risk and are not reflected in the consolidated balance sheets. The weighted-average rates paid and received for interest rate swaps at December 31, 2019 and 2018 , were as follows: Weighted-Average Interest Rate December 31, 2019 2018 Interest rate swaps: Paid Received Paid Received Cash flow hedges 4.81 % 4.64 % 4.81 % 5.36 % Non-hedging interest rate swaps - financial institution counterparties 4.93 4.13 5.02 4.67 Non-hedging interest rate swaps - customer counterparties 4.18 4.93 4.73 5.05 Gains and losses recognized on derivative instruments not designated as hedging instruments are as follows: (Dollars in thousands) Years Ended December 31, Derivatives not designated as hedging instruments: 2019 2018 2017 Amount of gain (loss) recognized in mortgage banking revenue (1) $ 3,079 $ (2,450 ) $ (259 ) Amount of (loss) gain recognized in other non-interest income (530 ) 584 707 ____________________________ (1) Gains and losses on these instruments are largely offset by market fluctuations in mortgage servicing rights. See Note 9 - Mortgage Banking for more information on components of mortgage banking revenue. Some interest rate swaps included in other assets were subject to a master netting arrangement with the counterparty in all years presented and could be offset against some amounts included in interest rate swaps included in other liabilities. The Company has chosen not to net these exposures in the consolidated balance sheets, and any impact of netting these amounts would not be significant. At December 31, 2019 and 2018, the Company had cash collateral on deposit with swap counterparties totaling $15.3 million and $1.9 million , respectively. These amounts are included in interest-bearing deposits in banks in the consolidated balance sheets and are considered restricted cash until such time as the underlying swaps are settled.

Share-based Payment Arrangement [Abstract]
Stock and Incentive Compensation Plans	Note 13 - Stock and Incentive Compensation Plans The Company has granted, and currently has outstanding, stock and incentive compensation awards subject to the provisions of the Company's 2012 Stock Incentive Plan ("2012 Plan"). Additionally, awards have been issued prior to the establishment of the 2012 Plan, some of which were still outstanding at December 31, 2019. The 2012 Plan is designed to provide flexibility to the Company regarding its ability to motivate, attract and retain the services of key officers, employees and directors. The 2012 Plan allows the Company to make grants of dividend equivalent rights, incentive stock options, non-qualified stock options, performance unit awards, restricted stock awards, restricted stock units and stock appreciation rights. At December 31, 2019 , the maximum number of shares of the Company's common stock available for issuance under the 2012 Plan was 950,152 shares. Share-based compensation cost charged to income for the years ended December 31, 2019 , 2018 and 2017 , is presented below: Years Ended December 31, (Dollars in thousands) 2019 2018 2017 Restricted stock $ 2,247 $ 1,462 $ 1,180 Stock options (1) — — (30 ) Total stock compensation expense $ 2,247 $ 1,462 $ 1,150 Related tax benefits recognized in net income $ 472 $ 307 $ 403 ____________________________ (1) Stock option expense for the year ended December 31, 2017 , included expense reversal related to 16,638 common stock options forfeited during the period. All remaining stock options became fully vested during the first quarter of 2017, with no further expense incurred after February 2017. Restricted Stock Grants The Company's restricted stock grants are time-vested awards and are granted to the Company's Board of Directors, executives and senior management team. The service period in which time-vested awards are earned ranges from one to five years . Time-vested awards are valued utilizing the fair value of the Company's stock at the grant date. These awards are recognized on the straight-line method over the requisite service period, with forfeitures recognized as they occur. The following table summarizes the Company's time-vested award activity: Years Ended December 31, 2019 2018 2017 Shares Weighted Average Grant-Date Fair Value Shares Weighted Average Grant-Date Fair Value Shares Weighted Average Grant-Date Fair Value Nonvested shares, January 1, 174,407 $ 35.01 61,293 $ 24.61 84,019 $ 24.22 Granted 37,641 32.77 151,324 37.51 35,913 25.14 Vested (59,344 ) 33.50 (36,209 ) 27.70 (55,003 ) 24.39 Forfeited (3,255 ) 30.21 (2,001 ) 37.47 (3,636 ) 24.12 Nonvested shares, December 31, 149,449 $ 35.15 174,407 $ 35.01 61,293 $ 24.61 During the year ended December 31, 2019 , no shares were retired by the Company upon vesting of restricted stock awards. During the year ended December 31, 2018 , award recipients surrendered and the Company retired 910 shares to cover taxes owed upon the vesting of restricted stock awards. During the year ended December 31, 2017, award recipients surrendered and the Company retired 11,843 shares to cover taxes owed upon the vesting of restricted stock awards. At December 31, 2019 , there was $4.2 million of total unrecognized compensation cost related to nonvested restricted shares awarded under the 2012 Plan. That cost is expected to be recognized over a weighted average period of 2.5 years. Stock Option Grants The Company issues common stock options to select officers and employees through individual agreements and as a result of obligations assumed in association with certain business combinations. As a result, both incentive and nonqualified stock options have been issued and may be issued in the future. The exercise price of each option varies by agreement and is based on either the fair value of the stock at the date of the grant in circumstances where option grants occurred or based on the previously committed exercise price in the case of options acquired through merger. No outstanding stock option has a term that exceeds twenty years , and all of the outstanding options are fully vested. The Company recognizes compensation cost for stock option grants over the required service period based upon the grant date fair-value, which is established using a Black-Scholes valuation model. The Black-Scholes valuation model uses assumptions of risk-free interest rate, expected term of stock options, expected stock price volatility and expected dividends. Forfeitures are recognized as they occur. The table below summarizes the status of the Company's stock options and changes during the years ended December 31, 2019 , 2018 and 2017 . (Dollars in thousands, except per share amounts) Number of Shares Weighted Average Exercise Price Weighted Average Remaining Contractual Term (in years) Aggregate Intrinsic Value (1) Outstanding at January 1, 2017 358,638 $ 11.37 7.79 $ 3,844 Exercised (22,500 ) 12.29 — 304 Forfeited and expired (16,638 ) 23.89 — — Outstanding at December 31, 2017 319,500 10.65 7.07 4,840 Exercised (45,500 ) 12.29 — — Outstanding at December 31, 2018 274,000 10.38 6.75 6,493 Exercised (20,000 ) 8.25 — — Outstanding at December 31, 2019 254,000 $ 10.55 5.81 $ 6,932 Exercisable at December 31, 2019 254,000 $ 10.55 5.81 $ 6,932 ____________________________ (1) The intrinsic value for stock options for periods at or prior to December 31, 2017, is calculated based on the difference between the weighted average exercised price of the underlying awards and the weighted average market price of the Company's common stock calculated over thirty days immediately prior to the last day of the Company's fiscal year.

Retirement Benefits [Abstract]
Employee Retirement Plan	Note 14 - Employee Retirement Plan Defined Contribution Retirement Plan The Company maintains the Origin Bancorp, Inc. Employee Retirement Plan ("Retirement Plan") that is a defined contribution benefit plan. During 2018, the Company amended and restated its Employee Stock Ownership Plan ("ESOP") as the Retirement Plan, a profit-sharing plan that allows contributions under section 401(k) of the Internal Revenue Code. The Retirement Plan covers substantially all employees who meet certain other requirements and employment classification criteria. Under the provisions of the Retirement Plan, the Company may make discretionary matching contributions on a percentage, not to exceed 6% , of a participant's elective deferrals. Any percentage(s) determined by the Company shall apply to all eligible persons for the entire plan year. Historically, the Company has matched 50% of the first 6% of eligible compensation deferred by a participant. Eligible compensation includes salaries, wages, overtime and bonuses, and excludes expense reimbursements and fringe benefits. In addition, the Company may make additional discretionary contributions out of current or accumulated net profit. Matching contributions are invested as directed by the participant. The total of the Company's contributions may not exceed limitations set forth in the Retirement Plan document or the maximum deductible under the Internal Revenue Code. Although it has not expressed any intention to do so, the Company has the right to terminate the Retirement Plan at any time. The total expense related to the Retirement Plan, including optional contributions, was $1.8 million , $1.6 million and $1.4 million for the years ended December 31, 2019 , 2018 and 2017 , respectively. In 2018, as a result of the Company’s initial public offering, the presentation requirement of Retirement Plan shares as deducted from permanent stockholders’ equity in the consolidated balance sheets was removed. The change in presentation is seen in the consolidated statement of changes in stockholders’ equity for the year ended December 31, 2018. Other Benefit Plans The Company has established non-qualified defined benefit plans for some of its key executives for which deferred compensation liabilities are recorded as a component of accrued expenses and other liabilities in the accompanying consolidated balance sheets. The deferred compensation liability was $9.8 million and $9.0 million as of December 31, 2019 and 2018, respectively. The expense recorded for the deferred compensation plan totaled $1.2 million for the year ended December 31, 2019, and $1.1 million for each of the years ended December 31, 2018 and 2017.

The Company remeasured certain deferred tax assets and liabilities in the period of enactment based on the rates at which they are expected to reverse in the future, which is generally 21%. The Company completed its analysis of the remeasurement of the Company's deferred tax asset within the measurement period and the amount is not materially different from the provisional amount recorded in 2017. During the first quarter of 2018, the Company adopted the provisions of ASU 2018-02 which resulted in a $282,000 adjustment from accumulated other comprehensive income to retained earnings.

Due to limitations on the amounts of these losses that can be recognized annually, the Company has determined that it is more likely than not that some of these net operating loss carryforwards will expire unused, and has established a $970,000 valuation allowance related to these carryforwards. The Company files a consolidated income tax return in the U.S. federal jurisdiction and various states. With few exceptions, the Company is no longer subject to income tax examinations by tax authorities in these taxing jurisdictions for the years before 2016.

The ASU was issued by the FASB in February 2018, to address the issue of other comprehensive income or loss that became stranded in AOCI as a result of the re-measurement of an entity's deferred income tax assets and liabilities following the reduction of the U.S. federal corporate tax rate from 35% to 21% pursuant to the enactment of the Tax Cuts and Jobs Act in December 2017. The Company also had certain current tax amounts stranded in AOCI that resulted from a tax accounting election to tax net gains and losses on AFS securities and cash flow hedges as current items beginning in 2016. The Company reclassifies the taxes from AOCI to earnings as the individual securities and hedges are realized. Due to the change in corporate tax rates, the Company had certain net gains and losses taxed at the 35% rate reflected in AOCI. As these transactions are realized over time, they will flow through income tax expense at the 21% rate. Rather than adjusting income tax expense for the difference as each of these securities and instruments are realized, the Company elected to adjust the difference (stranded tax effect) to retained earnings, consistent with the treatment of the deferred tax adjustment.

Capital and Regulatory Matters

Capital and Regulatory Matters	12 Months Ended

Banking and Thrift [Abstract]
Capital and Regulatory Matters	Note 17 - Capital and Regulatory Matters The Company (on a consolidated basis) and the 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 consolidated financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of 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. The Company is subject to the Basel III regulatory capital framework ("Basel III Capital Rules"), which includes a 2.5% capital conservation buffer effective for the Company as of January 1, 2019. 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, which includes dividend payments and stock repurchases and to pay discretionary bonuses to executive officers. Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios (set forth in the table below) of total, CET1 and Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined), and of Tier 1 capital (as defined) to average assets (as defined). Management believes, at December 31, 2019 and 2018, that the Company and the Bank met all capital adequacy requirements to which they are subject, including the capital buffer requirement. At December 31, 2019 and 2018, the 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," the Bank must maintain minimum total risk based, CET1, Tier 1 risk based and Tier 1 leverage ratios as set forth in the table.

Banking regulations may limit the amount of dividends that may be paid. Approval by regulatory authorities is required if the effect of dividends declared would cause the regulatory capital of the Bank to fall below specified minimum levels. Approval is also required if dividends declared and paid exceed the Bank's year-to-date net income combined with the retained net income for the preceding year, which was $86.5 million as of December 31, 2019. Stock Repurchases In a transaction that was consummated on August 2, 2019, we repurchased 300,000 shares of our common stock pursuant to our stock buyback program at a price per share of $33.50 for an aggregate purchase price of $10.1 million . As of the date of this report, approximately $29.9 million may still be purchased under the stock buyback program.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 18 - Commitments and Contingencies Credit Related Commitments In the normal course of business, the Company enters into financial instruments, such as commitments to extend credit and letters of credit, to meet the financing needs of its customers. Such instruments are not reflected in the accompanying consolidated financial statements until they are funded, although they expose the Company to varying degrees of credit risk and interest rate risk in much the same way as funded loans. Commitments to extend credit include revolving commercial credit lines, nonrevolving loan commitments issued mainly to finance the acquisition and development or construction of real property or equipment, and credit card and personal credit lines. The availability of funds under commercial credit lines and loan commitments generally depends on whether the borrower continues to meet credit standards established in the underlying contract and has not violated other contractual conditions. Loan commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee by the borrower. Credit card and personal credit lines are generally subject to cancellation if the borrower's credit quality deteriorates. A number of commercial and personal credit lines are used only partially or, in some cases, not at all before they expire, and the total commitment amounts do not necessarily represent future cash requirements of the Company. A substantial majority of the letters of credit are standby agreements that obligate the Company to fulfill a customer's financial commitments to a third party if the customer is unable to perform. The Company issues standby letters of credit primarily to provide credit enhancement to its customers' other commercial or public financing arrangements and to help them demonstrate financial capacity to vendors of essential goods and services. The contract amounts of these instruments reflect the Company's exposure to credit risk. The Company undertakes the same credit evaluation in making loan commitments and assuming conditional obligations as it does for on-balance sheet instruments and may require collateral or other credit support. These off-balance sheet financial instruments are summarized below: December 31, (Dollars in thousands) 2019 2018 Commitments to extend credit $ 1,374,055 $ 1,178,735 Standby letters of credit 39,344 46,860 In addition to the above, the Company guarantees the credit card debt of certain customers to the merchant bank that issues the credit cards. These guarantees are in place for as long as the guaranteed credit card is open. At December 31, 2019 and 2018, these credit card guarantees totaled $489,000 and $772,000 , respectively. This amount represents the maximum potential amount of future payments under the guarantee for which the Company would be responsible in the event of customer non-payment. At December 31, 2019 and 2018, the Company had FHLB letters of credit totaling $228.0 million and $172.0 million , respectively, available to secure public deposits, and for other purposes required or permitted by law. As of December 31, 2019, the Company held 21 unfunded letters of credit from the FHLB totaling $241.3 million with expiration dates ranging from January 15, 2020, to February 25, 2021. As of December 31, 2018, the Company held 16 unfunded letters of credit from the FHLB totaling $186.6 million with expiration dates ranging from February 14, 2019, to November 30, 2020. Management establishes an asset-specific allowance for lending-related commitments that are considered impaired and computes a formula-based allowance for performing consumer and commercial lending-related commitments. These are computed using a methodology similar to that used for the commercial loan portfolio, modified for expected maturities and probabilities of drawdown. The reserve for lending-related commitments was $1.8 million and $1.4 million at December 31, 2019 and 2018, respectively, and is included in other liabilities in the accompanying consolidated balance sheets. Loss Contingencies From time to time the Company is also party to various legal actions arising in the ordinary course of business. At this time, management does not expect that loss contingencies, if any, arising from any such proceedings, either individually or in the aggregate, would have a material adverse effect on the consolidated financial position or liquidity of the Company.

These loans were 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. Deposits from related parties held by the Company at December 31, 2019 and 2018 , amounted to $27.0 and $30.3 million , respectively.

Business Combinations [Abstract]
Business Combinations	Note 20 - Business Combinations All acquisitions are accounted for using the acquisition method of accounting. Accordingly, the assets and liabilities of acquired entities were recorded at their estimated fair values at the acquisition date. ASC 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market willing participants at the measurement date. The Company determines the estimated fair values after review and consideration of relevant information, including discounted cash flows, quoted market prices, third party valuations, and estimates made by management. Purchase price allocations on completed acquisitions may be modified through the measurement period which cannot exceed one year from the acquisition date. The excess of the purchase price over the estimated fair value of the net assets for tax-free acquisitions is recorded as goodwill, none of which is deductible for tax purposes. Acquisition-related costs are recognized separately from the acquisition and are expensed as incurred. The results of operations for the acquisition described below have been included in the Company's consolidated financial statements beginning on the acquisition date. Reeves, Coon & Funderburg On July 1, 2018, the Company acquired certain assets and assumed certain liabilities of Reeves, Coon & Funderburg, ("RCF"), a Louisiana-based independent insurance agency offering commercial, personal, health and life insurance. Total consideration was $9.5 million , which was comprised of 66,824 shares of its common stock at a price of $40.50 per share, based upon the closing stock price on the date of the acquisition, and $6.8 million in cash. As the consideration paid for RCF exceeded the provisional value of the tangible net assets acquired, goodwill of $4.5 million and identifiable intangible assets valued at $4.9 million associated primarily with RCF's customer relationships were recorded related to the acquisition. This goodwill resulted from the combination of expected operational synergies and increased market share.

Significant Accounting Polici_2

Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2019
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation . The consolidated financial statements include the accounts of the Company and all other entities in which Origin Bancorp, Inc. has a controlling financial interest, including the Bank and Davison Insurance Agency, LLC ("Davison Insurance"), doing business as Thomas & Farr Agency, and Reeves, Coon and Funderburg ("RCF"). All significant intercompany balances and transactions have been eliminated in consolidation. The Company's accounting and financial reporting policies conform, in all material respects, to accounting principles generally accepted in the United States ("U.S. GAAP") and to general practices within the financial services industry. The Company has evaluated subsequent events for potential recognition and/or disclosure through the date these consolidated financial statements were issued.
Reclassifications	Reclassifications . Certain amounts previously reported have been reclassified to conform to the current presentation. Such reclassifications had no effect on prior year net income or stockholders' equity.
Variable Interest Entities	Variable Interest Entities . 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 ("VIE") under U.S. 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 all, or at least a majority of, the voting interest. As defined in applicable accounting standards, 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. The Company's wholly owned subsidiaries CTB Statutory Trust I and First Louisiana Statutory Trust I are VIEs for which the Company is not the primary beneficiary. Accordingly, the accounts of these trusts are not included in the Company's consolidated financial statements.
Operating Segments	Operating Segments . Operating segments are components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision-maker in deciding how to allocate resources and in assessing performance. The Bank is the only significant subsidiary upon which management makes decisions regarding how to allocate resources and assess performance. Individual bank branches offer a group of similar services, including commercial, real estate and consumer loans, time deposits, checking and savings accounts, all with similar operating and economic characteristics. While the chief operating decision-maker monitors the revenue streams of the various products and services, operations are managed and financial performance is evaluated on a Company-wide basis. Accordingly, all of the community banking services and branch locations are considered by management to be aggregated into one reportable operating segment, community banking.
Use of Estimates	Use of Estimates . To prepare financial statements in conformity with U.S. 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. Material estimates that are subject to significant change in the near term are the allowance for loan losses, valuation of other real estate owned, fair value of mortgage servicing rights, realization of deferred tax assets, fair values of financial instruments and the status of contingencies. Actual results could differ from those estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents . For purposes of the statement of cash flows, the Company considers all cash on hand, demand deposits with other banks, federal funds sold and short term interest-bearing cash items with an original maturity less than 90 days to be cash equivalents. The Company maintains deposits with other financial institutions in amounts that exceed federal deposit insurance coverage. Furthermore, federal funds sold are essentially uncollateralized loans to other financial institutions. Management regularly evaluates the credit risk associated with the counterparties to these transactions and believes that the Company is not exposed to any significant credit risks on cash and cash equivalents.
Securities	Securities . The Company accounts for debt and equity securities as follows: Available for Sale ("AFS") - Debt and equity securities that will be held for indefinite periods of time, including securities that may be sold in response to changes in market interest or prepayment rates, needs for liquidity and changes in the availability of and the yield of alternative investments are classified as AFS. These assets are carried at fair value. Fair value is determined using published quotes. If quoted market prices are not available, fair values are based on other methods including, but not limited to the discounting of cash flows. Held to Maturity ("HTM") - Debt securities that management has the positive intent and ability to hold until maturity are classified as HTM and are carried at their remaining unpaid principal balance, net of unamortized premiums or unaccreted discounts. Securities Carried at Fair Value through Income - Debt securities for which the Company has elected the fair value option for accounting are classified as securities carried at fair value through income. Management has elected the fair value option for these items to offset the corresponding change in fair value of related interest rate swap agreements. Fair value is determined using discounted cash flows and credit quality indicators. Changes in fair value are reported through the consolidated statements of income as a part of other noninterest income. Unrealized gains and losses on AFS securities are excluded from earnings and reported net of tax in accumulated other comprehensive income until realized. Declines in the fair value of AFS and HTM securities below their cost are reflected in earnings as realized losses to the extent the impairment is deemed to be other-than-temporary credit losses. In estimating other-than-temporary impairment losses, management considers (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) management's intent and ability to retain the investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value. The amount of the impairment related to other factors is recognized in other comprehensive income unless there is no ability or intent to hold to recovery. Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities to the earlier of the call date or maturity date. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method.
Non-marketable Equity Securities Held in Other Financial Institutions	Non-marketable Equity Securities Held in Other Financial Institutions . Securities with limited marketability, such as stock in the Federal Reserve Bank of Dallas ("FRB") or the Federal Home Loan Bank of Dallas ("FHLB"), are carried at cost, less impairment, if any. These investments in stock do not have readily determinable fair values. The Company's remaining equity investments in other financial institutions, totaling $12.1 million and $11.7 million at December 31, 2019 and 2018
Loans Held For Sale	Loans Held for Sale . Loans held for sale include mortgage loans and are carried at fair value, with unrealized gains and losses recorded in the consolidated statements of income. Forward commitments to sell mortgage loans are acquired to reduce market risk on mortgage loans in the process of origination and mortgage loans held for sale. The forward commitments acquired by the Company for mortgage loans in process of origination are mandatory forward commitments, and the Company is required to substitute another loan or to buy back the commitment if the original loan does not fund. Typically, the Company delivers the mortgage loans within a few days after the loans are funded. These commitments are derivative instruments carried at fair value. Gains and losses resulting from sales of mortgage loans are realized when the respective loans are sold to investors. Gains and losses are determined by the difference between the selling price (including the fair value of any items such as mortgage servicing rights) and the carrying amount of the loans sold. Fees received from borrowers to guarantee the funding of mortgage loans held for sale are recognized as income or expense when the loans are sold or when it becomes evident that the commitment will not be used.
Loans	Loans . Loans that management has the intent and ability to hold for the foreseeable future, or until maturity or payoff, are reported at their outstanding unpaid principal balances adjusted for charge-offs, the allowance for loan losses, and any deferred fees or costs on originated loans. Interest income is accrued on the unpaid principal balance. Loan origination fees, and certain direct origination costs, are deferred and amortized as a yield adjustment over the lives of the related loans using the interest method. Late fees are recognized as income when earned, assuming collectability is reasonably assured. The Company has elected the fair value option on a small portion of its loans held for investment, with changes in fair value recorded in noninterest income. For these loans, the earned current contractual interest payment is recognized in interest income. Loan origination costs and fees are recognized in earnings as incurred and not deferred. Because these loans are recognized at fair value, the Company's allowance for loan losses policy does not apply to these loans. Fair value is determined using discounted cash flows and credit quality indicators. In addition to loans issued in the normal course of business, the Company considers overdrafts on customer deposit accounts to be loans and classifies these overdrafts as loans in its consolidated balance sheets. Loans are placed on nonaccrual status when management believes that the borrower's financial condition, after giving consideration to economic and business conditions and collection efforts, is such that collection of interest is doubtful, or generally when loans are 90 days or more past due. When accrual of interest is discontinued, all unpaid accrued interest is reversed. Past due status is based on contractual terms of the loan. Interest income on nonaccrual loans may be recognized to the extent cash payments are received, but payments received are usually applied to principal. Nonaccrual loans are generally returned to accrual status when principal and interest payments are less than 90 days past due, the customer has made required payments for at least six months, and the Company reasonably expects to collect all principal and interest.
Allowance for Loan Losses	Allowance for Loan Losses . The allowance for loan losses is established as losses are estimated to have occurred through a provision for loan losses charged to earnings. The allowance for loan losses is evaluated on a regular basis by management and is based upon management's periodic review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower's ability to repay, estimated value of any underlying collateral, and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. Loans are charged off against the allowance for loan losses when management believes the loss is confirmed. Subsequent recoveries, if any, are credited to the allowance. The allowance consists of allocated and general components. The allocated component relates to loans that are classified as impaired, and an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan is lower than the carrying value of that loan. The general component relates to loans that are not classified as impaired and is based on historical charge-off experience and the expected loss, given default, derived from the Company's internal risk rating process. Other adjustments may be made to the allowance for pools of loans after an assessment of internal or external influences on credit quality that are not fully reflected in the historical loss or risk rating data. Delinquency statistics are updated at least monthly and are the most meaningful indicator of the credit quality of one-to-four single family residential, home equity loans and lines of credit and other consumer loans. Internal risk ratings are considered the most meaningful indicator of credit quality for commercial and industrial, construction, and commercial real estate loans. Internal risk ratings are a key factor in identifying loans that are individually evaluated for impairment and impact management's estimates of loss factors used in determining the amount of the allowance for loan losses. Internal risk ratings are updated on a regular basis. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Impaired loans include nonperforming loans and loans modified in troubled debt restructurings ("TDRs"). TDRs are loans for which the contractual terms on the loan have been modified and both of the following conditions exist: (1) the borrower is experiencing financial difficulty and (2) the restructuring constitutes a concession. Concessions could include a reduction in the interest rate on the loan, payment extensions, forgiveness of principal, forbearance or other actions intended to maximize collection. The Company assesses all loan modifications to determine whether they constitute a TDR. All TDRs are considered impaired loans. Impairment is measured on a loan-by-loan basis by either the present value of expected future cash flows discounted at the loan's effective interest rate, the loan's obtainable market price or the fair value of the collateral if the loan is collateral dependent. 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.
Premises and Equipment, net	Premises and Equipment, net . Land is carried at cost. Buildings and improvements are stated at cost less accumulated depreciation computed using the straight-line method over the estimated useful lives of the assets, which range from 35 to 39 years. Furniture, fixtures, and equipment are stated at cost less accumulated depreciation computed using the straight-line method over the estimated useful lives of the assets, which range from three to seven years .
Leases	Leases. The Company adopted ASU No. 2016-02 — Leases (Topic 842) as of January 1, 2019, and recorded a $19.7 million right-of-use ("ROU") asset offset by a $19.4 million lease liability, recognizing a net after tax $321,000 cumulative effect adjustment credit to retained earnings. The Company elected the package of practical expedients, which among other things, does not require reassessment of lease classification. The Company determines if an arrangement is a lease at inception. Operating lease assets are included in accrued interest receivable and other assets, operating lease liabilities are included in accrued expenses and other liabilities in the Company's consolidated balance sheets. The Company has made an accounting policy election not to recognize short-term lease assets and liabilities (less than a 12-month term) or immaterial equipment and server space leases in its balance sheets; instead, the Company recognizes the lease expense for these leases on a straight-line basis over the life of the lease. The Company has no material finance leases. ROU assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. ROU lease assets and liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term. The Company uses an estimated incremental collateralized borrowing rate, which is derived from information available at the lease commencement date and gives consideration to the applicable FHLB borrowing rates, when determining the present value of lease payments. The Company's lease terms include options to extend a lease when it is reasonably certain that the Company will exercise that option. The Company's lease agreements do not contain any residual value guarantees. All of the Company's operating long-term leases are real estate leases, which are accounted for as a single lease component.
Mortgage Servicing Rights and Transfers of Financial Assets	Mortgage Servicing Rights and Transfers of Financial Assets . Gains or losses on "servicing-retained" loan sale transactions generally include a component reflecting the differential between the contractual interest rate of the loan and the interest rate to be received by the investor. The present value of the estimated future profit for servicing the loans is also taken into account in determining the amount of gain or loss on the sale of these loans. For loans sold servicing-retained, the fair value of mortgage servicing rights is recorded as an asset, with their value estimated using a discounted cash flow methodology to arrive at the present value of future expected earnings from the servicing of the loans. Significant model inputs include prepayment speeds, discount rates, and servicing costs. Servicing revenues are based on a contractual percentage of the outstanding principal or a fixed amount per loan and are recorded as income when earned. Loans sold into the secondary market are considered transfers of financial assets. These transfers are accounted for as sales when control over the asset has been surrendered, which is deemed to have occurred when: an asset does not have any claims to it by the transferor or their creditors, including in bankruptcy or other receivership situations; the transferee obtains the unconditional right to pledge or exchange the asset; or the transfer does not include a repurchase provision above the limited recourse provisions of these loan sales.
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities . Some interest rate swaps included in other assets were subject to a master netting arrangement with the counterparty in all years presented and could be offset against some amounts included in interest rate swaps included in other liabilities. The Company has chosen not to net these exposures in the consolidated balance sheets, and any impact of netting these amounts would not be significant. Risk Management Objective of Using Derivatives The Company enters into derivative financial instruments to manage risks related to differences in the amount, timing, and duration of the Company's known or expected cash receipts and its known or expected cash payments, as well as to manage changes in fair values of some assets which are marked at fair value through the consolidated statement of income on a recurring basis. Cash Flow Hedges of Interest Rate Risk The Company is a party to an interest rate swap agreement under which the Company receives interest at a variable rate and pays at a fixed rate. The derivative instrument represented by this swap agreement is designated as a cash flow hedge of the Company's forecasted variable cash flows under a variable-rate term borrowing agreement. During the term of the swap agreement, the effective portion of changes in the fair value of the derivative instrument are recorded in accumulated other comprehensive income and subsequently reclassified into earnings in the periods that the hedged forecasted variable-rate interest payments affected earnings. There was no ineffective portion of the change in fair value of the derivative recognized directly in earnings. The entire swap fair value will be reclassified into earnings before the expiration date of the swap agreement. Derivatives Not Designated as Hedges Customer interest rate derivative program The Company offers certain derivatives products, primarily interest rate swaps, directly to qualified commercial banking customers to facilitate their risk management strategies. In some instances, the Company acts only as an intermediary, simultaneously entering into offsetting agreements with unrelated financial institutions, thereby mitigating its net risk exposure resulting from such transactions without significantly impacting its results of operations. Because the interest rate derivatives associated with this program do not meet hedge accounting requirements, changes in the fair value of both the customer derivatives and any offsetting derivatives are recognized directly in earnings as a component of noninterest income. Mortgage banking derivatives The Company enters into certain derivative agreements as part of its mortgage banking and related risk management activities. These agreements include interest rate lock commitments on prospective residential mortgage loans and forward commitments to sell these loans to investors on a mandatory delivery basis. The Company also economically hedges the value of MSRs by entering into a series of commitments to purchase mortgage-backed securities in the future.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets . Goodwill, which represents the excess of cost over the fair value of the net assets of an acquired business, is not amortized but tested for impairment on an annual basis, which is October 1 for the Company, or more often if events or circumstances indicate that there may be impairment. Other intangible assets, such as relationship based intangibles and core deposit intangibles, are amortized on a basis consistent with the receipt of economic benefit to us. Such assets are evaluated at least annually as to the recoverability of their carrying value for potential impairment. In the quarter following the period in which identified intangible assets become fully amortized, the fully amortized balances are removed from the gross asset and accumulated amortization amounts.
Other Real Estate Owned	Other Real Estate Owned .
Overnight Repurchase Agreements with Depositors	Overnight Repurchase Agreements with Depositors . The Company enters into agreements under which it sells securities subject to an obligation to repurchase the same or similar securities. Under these arrangements, the Company may transfer legal control over the assets but still retain effective control through an agreement that both entitles and obligates it to repurchase the assets. Securities sold under agreements to repurchase generally mature on the banking day following that on which the investment was initially sold and are treated as collateralized financing transactions which are recorded at the amounts at which the securities were sold plus accrued interest. Interest rates and maturity dates of the securities involved vary and are not intended to be matched with funds from customers.
Mortgage Banking Revenue	Mortgage Banking Revenue . This revenue category primarily reflects the Company's mortgage production, sales and mortgage servicing revenue, including fees and income derived from mortgages originated with the intent to sell; mortgage sales and servicing; and the impact of risk management activities associated with the mortgage pipeline and mortgage servicing rights ("MSRs"). This revenue category also includes gains and losses on sales and changes in fair value for mortgage loans originated with the intent to sell and measured at fair value under the fair value option. Changes in the fair value of MSRs are reported in mortgage banking revenue. Net interest income from mortgage loans is recorded in interest income.
Income Taxes	Income Taxes . Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax bases of assets and liabilities, computed using enacted tax rates. A valuation allowance, if needed, reduces 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 did not have any amount accrued with respect to uncertainty in income taxes at December 31, 2019 and 2018 .
Stock-Based Compensation	Stock-Based Compensation . The cost of employee services received in exchange for stock options or restricted stock grants are measured using the fair value of the award on the grant date and is recognized over the service period.
Other Investments	Other Investments . The Company accounts for investments in limited partnerships, limited liability companies ("LLCs"), and other privately held companies using either the equity method of accounting or at amortized cost net of impairments and observable price changes. The accounting treatment depends upon the Company's percentage ownership or degree of management influence. Under the equity method of accounting, the Company records its initial investment at cost. Subsequently, the carrying amount of the investment is increased or decreased to reflect its share of income or loss of the investee. The Company's recognition of earnings or losses from an equity method investment is based on its ownership percentage in the investee and the investee's earnings for the reporting period, and is recorded on a one-quarter lag. All of the Company's investments in limited partnerships, LLCs, and other companies are privately held, and their fair values are not readily available. Management evaluates the investments in investees for impairment based on the investee's ability to generate cash through its operations or obtain alternative financing, and other subjective factors. There are inherent risks associated with investments in such companies, which may result in volatility in the consolidated statements of income in future periods.
Investments in Tax Credit Entities	Investments in Tax Credit Entities . As part of its Community Reinvestment Act responsibilities and due to their favorable economic characteristics, the Company invests in tax credit-motivated projects primarily in the markets it serves. These projects are directed at tax credits issued under Low-Income Housing Tax Credits. The Company generates returns on tax credit motivated projects through the receipt of federal, and if applicable, state tax credits. The federal tax credits are recorded as an offset to the income tax provision in the year that they are earned under federal income tax law – over 10 to 15 years beginning in the year in which rental activity commences. These credits, if not used in the tax return for the year of origination, can be carried forward for 20 years. The Company invests in a tax credit entity, usually an LLC, which owns the real estate. The Company receives a nonvoting interest in the entity that must be retained during the compliance period for the credits ( 15 years for Low-Income Housing Tax Credit programs). Control of the tax credit entity rests in the 0.1% interest general partner, who has the power and authority to make decisions that impact economic performance of the project and is required to oversee and manage the project. Due to the lack of any voting, economic, or managerial control, and due to the contractual reduction in the investment, the Company accounts for its investment by amortizing the investment, beginning at the issuance of the certificate of occupancy of the project, over the compliance period, as management believes any potential residual value in the real estate will have limited value. Amortization is included as a component of income tax expense.
Earnings Per Share	Earnings Per Share . Basic and diluted earnings per common share for periods beginning after December 31, 2018, are calculated using the treasury method. Under the treasury method, basic earnings per share is calculated as net income divided by the weighted average number of common shares outstanding during the period. Diluted earnings per share includes the dilutive effect of additional potential common shares issuable under stock options and restricted stock awards. Basic and diluted earnings per common share for periods ending on or before December 31, 2018, were calculated using the two-class method. The two-class method is an earnings allocation formula that determines earnings per share for each share of common stock and participating securities according to dividends declared (distributed earnings) and participation rights in undistributed earnings. Distributed and undistributed earnings were allocated between common and participating security stockholders based on their respective rights to receive dividends. Share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents were considered participating securities (e.g., restricted stock grants). Preferred stock that receives dividends based on dividends paid on common stock was also considered a participating security (e.g., Series D preferred stock). Net income attributable to common stockholders was then divided by the weighted average number of common shares outstanding during the period, net of participating securities. Diluted income per common share considers common stock issuable under the assumed release of unvested restricted stock awards, convertible preferred stock being converted to common stock, and the assumed exercise of stock options granted. The dilutive effect of share-based payment awards that are not deemed to be participating securities is calculated using the treasury stock method, which assumes that the proceeds from exercise are used to purchase common stock at the average market price for the period. The dilutive effect of participating securities is calculated using the more dilutive of the treasury stock method (which assumes that the participating securities are exercised/released) or the two-class method (which assumes that the participating securities are not exercised/released and earnings are reallocated between common and participating security stockholders). Potentially dilutive common stock equivalents are excluded from the computation of diluted earnings per common share in periods in which the effect would be antidilutive.
Effect of Recently Adopted Accounting Standards and Effect of Newly Issued But Not Yet Effective Accounting Standards	Effect of Recently Adopted Accounting Standards ASU No. 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The amendments in this update allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. Since these amendments only relate to the reclassification of the income tax effects of the Tax Cuts and Jobs Act, the underlying guidance that requires that the effect of a change in tax laws or rates be included in income from continuing operations is not affected. These amendments require that an entity disclose a description of the accounting policy for releasing income tax effects from accumulated other comprehensive income. These amendments are effective for fiscal years beginning after December 15, 2018, and interim periods within those years. Early adoption is permitted, including adoption in any interim period, for reporting periods for which financial statements have not yet been issued. These amendments should be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act is recognized. Rather than adjusting income tax expense for the differences as the effect of the change in the U.S. federal corporate income tax rates are realized, the Company elected to adjust the difference (stranded tax effect) to retained earnings, consistent with the treatment of the deferred tax adjustment. The Company adopted this guidance during the first quarter of 2018, which resulted in a reclassification of $282,000 from accumulated other comprehensive income to retained earnings. The Company's policy is to release material stranded tax effects on a specific identification basis. ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. ASU 2017-12 permits hedge accounting for risk components in hedging relationships involving nonfinancial risk and interest rate risk. It also changes the guidance for designating fair value hedges of interest rate risk and for measuring the change in fair value of the hedged item in fair value hedges of interest rate risk. In addition to the amendments to the designation and measurement guidance for qualifying hedging relationships, the amendments in this ASU also align the recognition and presentation of the effects of the hedging instrument and the hedged item in the consolidated financial statements. This ASU requires an entity to present the earnings effect of the hedging instrument in the same line item in the statement of income in which the earnings effect of the hedged item is reported. For public entities, these amendments were effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early application was permitted. The Company analyzed its hedges and determined that the amendments in this ASU were not applicable to any hedge relationships in effect and therefore, no transition adjustment was necessary. The Company adopted this ASU during the first quarter of 2018. ASU No. 2016-15 —Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. ASU 2016-15 adds or clarifies guidance on the classification of certain cash receipts and payments in the statement of cash flows. The Company adopted this guidance on January 1, 2018, and, as a result, reclassified $844,000 of return of capital proceeds from limited partnership investments from operating activities to investing activities for the year ended December 31, 2017. ASU No. 2016-02 — Leases (Topic 842). ASU 2016-02 requires lessees to recognize a lease liability and a right-of use ("ROU") asset on the balance sheet for operating leases. Accounting for finance (formerly known as capital) leases is substantially unchanged. The Company adopted this ASU as of January 1, 2019. Please see the Leases paragraphs above in this footnote for more information. ASU No. 2016-01 —Financial Instruments —Overall (Subtopic 825-10). The Company adopted this update effective January 1, 2018. The main provisions are to eliminate the AFS classification of accounting for equity securities and to adjust the fair value disclosures for financial instruments carried at amortized cost such that the disclosed fair values represent an exit price as opposed to an entry price. The majority of the Company's equity investments qualify for the practical expedient allowed for equity securities without a readily determinable fair value, such that the Company has elected to carry these securities at cost adjusted for any observable transactions during the period, less any impairment. To date, no impairment has been recorded on the Company's investments in equity securities which do not have readily determinable fair values. The disclosure of fair value of the loan and interest-bearing deposit portfolios has been presented using an exit price methodology and had an immaterial impact on the Company's financial position. ASU No. 2014-09 —Revenue from Contracts with Customers ( Topic 606 ). The Company adopted this ASU on January 1, 2018, which outlines a single comprehensive revenue recognition model for entities to follow in accounting for revenue from contracts with customers. The implementation of this new guidance did not have a material impact on the measurement or recognition of revenue and no cumulative effect adjustment was recorded to opening retained earnings. Results for reporting periods beginning after January 1, 2018, are presented under Topic 606, while prior period amounts were not adjusted and continue to be reported in accordance with the Company's historic accounting under Topic 605. The majority of the Company's revenue is generated from sources outside the scope of Topic 606. Interest and fees on loans, income from investment securities and mortgage banking revenue are all outside the scope of Topic 606 and are recorded in adherence with U.S. GAAP. Service charges and fees on deposit accounts, credit card interchange, insurance commission and fee income, as well as gains and losses on the sale of other assets including OREO are within the scope of Topic 606; however, the recognition of these revenue streams did not change significantly upon adoption of Topic 606. Descriptions of the Company's revenue generating activities that are within the scope of Topic 606 are described below. Service charges and fees on deposit accounts Service charges and fees on deposit accounts are primarily comprised of maintenance fees, service fees, stop payment and insufficient funds fees. The Company's performance obligation for service fees or other fees covering a period of time are generally satisfied, and related revenue recognized, over the period in which the service is provided. The Company's performance obligations for transactional-based fees are generally satisfied, and related revenue recognized, at a point in time. Insurance commission and fee income The Company earns commission income through production on behalf of insurance carriers and also earns fee income by providing complementary services such as collection of premiums. In most instances the Company considers the performance obligation to be complete at the time the service was rendered. Credit card interchange income The Company records credit card interchange income at a point in time as card transactions occur. The Company's performance obligation for these transactions is deemed to have occurred upon completion of each transaction. The amounts are included as a component of other income in the consolidated statements of income. Gain or loss on sale of other assets and OREO In the normal course of business, the Company recognizes the sale on other assets and OREO, along with any gain or loss, when control of the property transfers to the buyer through an executed contractual agreement. The transaction price is fixed, and on occasion the Company will finance a portion of the purchase price of the transferred asset. ASU No. 2018-15, Intangibles, Goodwill and Other, Internal Use Software - (Topic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract. The amendments in this ASU align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). Accordingly, the amendments require an entity (customer) in a hosting arrangement that is a service contract to follow the guidance in Subtopic 350-40 to determine which implementation costs to capitalize as an asset related to the service contract and which costs to expense. The amendments also require the entity (customer) to expense the capitalized implementation costs of a hosting arrangement that is a service contract over the term of the hosting arrangement, which includes reasonably certain renewals. For public business entities that file reports with the Securities and Exchange Commission ("SEC"), the amendments in the update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, early adoption is permitted. The Company prospectively adopted ASU 2018-15 effective October 1, 2018. As a result of this implementation, capitalized costs relating to internal use software totaled $455,000 at December 31, 2018, and are expensed over the useful life of the contract rather than expensed as incurred. The asset is reflected on the consolidated balance sheets in accrued interest receivable and other assets and the related amortization expense is reflected in data processing expense on the consolidated statements of income. Effect of Newly Issued But Not Yet Effective Accounting Standards ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments; ASU No. 2018-19, Codification Improvements to Topic 326, Financial Instruments - Credit Losses; ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments; ASU 2019-05, Financial Instruments - Credit Losses (Topic 326): Targeted Transition Relief; ASU 2019-11, Codification Improvements to Topic 326, Financial Instruments - Credit Losses; collectively, the "ASUs". These ASUs introduce and amend ASC Topic 326, Financial Instruments - Credit Losses and amend guidance on reporting credit losses for assets held at amortized cost basis and available for sale debt securities. For assets held at amortized cost basis, Topic 326 eliminates the current incurred loss approach and, instead, requires an entity to reflect its current estimate of all expected credit losses. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial assets to present the net amount expected to be collected. This guidance also changes the accounting for purchased loans and securities with credit deterioration. Topic 326 also applies to off-balance sheet exposures such as unfunded loan commitments, letters of credit and other financial guarantees. Expected credit losses related to off-balance sheet exposures will be presented as a liability rather than as an allowance. The ASUs allow for certain accounting policy elections related to the treatment of accrued interest, the amortized cost components of charged-off balances, the treatment of prepayment assumptions related to discounted cash flow methodology and a limited use of the fair value option. Topic 326 retains many of the current required disclosures, expands certain disclosures and adds some additional disclosures. For available for sale debt securities, entities are required to determine whether all or a portion of the unrealized loss on those securities is a credit loss. The guidance also eliminates the option for management to consider the length of time a security has been in an unrealized loss position as a factor in determining whether or not a credit loss exists. Topic 326 requires that credit losses be presented as an allowance for credit losses rather than as a direct write-down of the investment balance. This change allows improvements in credit quality to be recognized in earnings. The Company has made significant changes in the processes and procedures to calculate the allowance for credit losses, including changes in assumptions and estimates to consider expected credit losses over the life of the loan versus the current accounting practice that utilizes the incurred loss model. In order to validate the operations and outputs associated with these ASUs, the Company is running parallel models and has made substantial progress toward (1) defining risk characteristics and creating loan pools based on those characteristics, (2) determining internal and external data sources that will be used, (3) deciding the loss methodologies that will be used, (4) calculating historical loss data and making appropriate adjustments using internal and external sources, (5) developing and refining an economic forecasting model, (6) documenting processes, procedures and model assumptions, (7) developing accounting policies relevant to the credit loss estimation process and (8) developing internal control procedures around the credit loss estimation process. For public business entities that are SEC filers, the ASUs are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company will implement these amendments in its fiscal year beginning January 1, 2020. Upon adoption of these ASUs, the Company recognized a one-time, after tax cumulative effect adjustment of $760,000 to retained earnings at the beginning of the first quarter of 2020, increasing the allowance for credit losses by approximately $1.3 million and decreasing the off-balance sheet reserve by $382,000 . The Company's held-to-maturity and available for sale securities were not materially affected by the adoption of this ASU due to the nature of the portfolios which consist of approximately 73% of U.S. government agency and mortgage-backed securities. Our adjustment to the allowance for credit losses at the transition date may vary from our estimate due to refinements in the loss estimation models or factors. ASU No. 2018-13, Fair Value Measurement - (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. The amendments in this ASU modify the disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement , based on the concepts in Financial Accounting Standards Board ("FASB") Concepts Statement, Conceptual Framework for Financial Reporting—Chapter 8: Notes to Financial Statements, including the consideration of costs and benefits. For public business entities that file reports with the SEC, the amendments in the update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The implementation of this ASU will not materially impact the consolidated financial statements. Certain fair value disclosures will be revised to comply with this ASU. ASU No. 2019-10, Financial Instruments —Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842). ASU 2019-10 defers the effective dates related to (1) ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (Credit Losses), (2) ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities (Hedging) and (3) ASU 2016-02, Leases (Topic 842) (Leases) for non-SEC filers. The ASU amends the effective date for SEC filers for ASU 2017-04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment to periods beginning after December 15, 2019, aligning it with the effective date for Credit Losses. The impact of this ASU alleviates step 2 of the goodwill impairment test effective January 1, 2020. The implementation of this ASU will not materially impact the consolidated financial statements or disclosures. The effective date of this ASU was November 15, 2019. ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. ASU 2019-12 simplifies the accounting for income taxes by eliminating some exceptions to the general approach in Accounting Standards Codification (ASC) 740, Income Taxes. It also clarifies certain aspects of the existing guidance to promote more consistent application, among other things. The amendments in the update are effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. The Company is evaluating the impact of this ASU on the consolidated financial statements and disclosures. During the first quarter of 2018, the Company adopted ASU 2018-02. The ASU was issued by the FASB in February 2018, to address the issue of other comprehensive income or loss that became stranded in AOCI as a result of the re-measurement of an entity's deferred income tax assets and liabilities following the reduction of the U.S. federal corporate tax rate from 35% to 21% pursuant to the enactment of the Tax Cuts and Jobs Act in December 2017. The Company also had certain current tax amounts stranded in AOCI that resulted from a tax accounting election to tax net gains and losses on AFS securities and cash flow hedges as current items beginning in 2016. The Company reclassifies the taxes from AOCI to earnings as the individual securities and hedges are realized. Due to the change in corporate tax rates, the Company had certain net gains and losses taxed at the 35% rate reflected in AOCI. As these transactions are realized over time, they will flow through income tax expense at the 21% rate. Rather than adjusting income tax expense for the difference as each of these securities and instruments are realized, the Company elected to adjust the difference (stranded tax effect) to retained earnings, consistent with the treatment of the deferred tax adjustment.
Loans Placed on Nonaccrual Status	All interest accrued but not received for loans placed on nonaccrual status is reversed against interest income. Subsequent receipts on nonaccrual loans are recorded as a reduction of principal, and interest income is recorded only after principal recovery is reasonably assured. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. TDRs are included in certain loan categories within impaired loans.
Fair Value of Financial Instruments	Derivatives Fair values for interest rate swap agreements are based upon the amounts that would be required to settle the contracts. Fair values for derivative loan commitments and forward loan sale commitments are based on fair values of the underlying mortgage loans and the probability of such commitments being exercised. Significant management judgment and estimation is required in determining these fair value measurements. Securities Available for Sale Securities classified as available for sale are reported at fair value utilizing Level 1, Level 2 or Level 3 inputs. For Level 2 securities, the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, market consensus prepayment speeds, credit information and the security's terms and conditions, among other things. In order to ensure the fair values are consistent with Accounting Standards Codification ("ASC") 820, Fair Value Measurements and Disclosures , the Company periodically checks the fair value by comparing them to another pricing source, such as Bloomberg LP. The third-party pricing service is subject to an annual review of internal controls in accordance with the Statement on Standards for Attestation Engagements No. 16, which was made available to the Company. In certain cases where Level 2 inputs are not available, securities are classified within Level 3 of the hierarchy. Mortgage Servicing Rights ("MSR") Fair Values of Assets Recorded on a Recurring Basis for which the Fair Value Option has been Elected Certain assets are measured at fair value on a recurring basis due to the Company's election to adopt fair value accounting treatment for those assets. This election allows for a more effective offset of the changes in fair values of the assets and the derivative instruments used to economically hedge them without the burden of complying with the requirements for hedge accounting under ASC 815, Derivatives and Hedging. Fair value is the exchange price that is expected to 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. Certain assets and liabilities are recorded in the Company's consolidated financial statements at fair value. Some are recorded on a recurring basis and some on a non-recurring basis. The Company utilizes fair value measurement to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The determination of fair values of financial instruments often requires the use of estimates. In cases where quoted market values in an active market are not available, the Company utilizes valuation techniques that are consistent with the market approach, the income approach and/or the cost approach to estimate the fair values of its financial instruments. Such valuation techniques are consistently applied. A hierarchy for fair value has been established which categorizes the valuation techniques into three levels used to measure fair value. The three levels are as follows: Level 1 - Fair value is based on unadjusted quoted prices in active markets for identical assets or liabilities. Level 2 - Fair value is based on significant other observable inputs that are generally determined based on a single price for each financial instrument provided to the Company by an unrelated third-party pricing service and is based on one or more of the following: • Quoted prices for similar, but not identical, assets or liabilities in active markets; • Quoted prices for identical or similar assets or liabilities in markets that are not active; • Inputs other than quoted prices that are observable, such as interest rate and yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates; • Other inputs derived from or corroborated by observable market inputs. Level 3 - Prices or valuation techniques that require inputs that are both significant and unobservable in the market. These instruments are valued using the best information available, some of which is internally developed, and reflects the Company's own assumptions about the risk premiums that market participants would generally require and the assumptions they would use. The following methodologies were used to measure the fair value of financial assets valued on a recurring basis for which the fair value option was elected: Securities at Fair Value through Income Securities carried at fair value through income are valued using a discounted cash flow with a credit spread applied to each instrument based on the credit worthiness of each issuer. Credit spreads ranged from 83 to 227 basis points at both December 31, 2019 and 2018. The Company believes the fair value approximates an exit price. Loans Held for Sale Fair values for loans held for sale are established using anticipated sale prices for loans allocated to a sale commitment, and those unallocated to a commitment are valued based on the interest rate and term for similar loans allocated. The Company believes the fair value approximates an exit price. Loans Held for Investment For loans held for investment for which the fair value option has been elected, fair values are calculated using a discounted cash flow model with inputs including observable interest rate curves and unobservable credit adjustment spreads based on credit risk inherent in the loan. Credit spreads ranged from 290 to 413 basis points at December 31, 2019 , and ranged from 290 to 413 basis points at December 31, 2018 . The Company believes the fair value approximates an exit price. Fair Value of Assets Recorded on a Nonrecurring Basis Equity Securities without Readily Determinable Fair Values Equity securities without readily determinable fair values totaled $39.8 million at December 31, 2019 , and are shown on the face of the consolidated balance sheets. The majority of the Company's equity investments qualify for the practical expedient allowed for equity securities without a readily determinable fair value, such that the Company has elected to carry these securities at cost adjusted for any observable transactions during the period, less any impairment. To date, no impairment has been recorded on the Company's investments in equity securities that do not have readily determinable fair values. Government National Mortgage Association Repurchase Asset The Company recorded $27.9 million and $30.6 million , respectively, at December 31, 2019 and 2018, for Government National Mortgage Association ("GNMA") repurchase assets included in mortgage loans held for sale on the consolidated balance sheets. The assets are valued at the lower of cost or market and, where market is lower than cost, valued using anticipated sale prices for loans allocated to a sale commitment, and those unallocated to a commitment are valued based on the interest rate and term for similar loans allocated. The Company believes the fair value approximates an exit price. Please see Note 9 - Mortgage Banking for more information on the GNMA repurchase asset. Collateral Dependent Impaired Loans Loans for which it is probable that the Company will not collect all principal and interest due according to contractual terms are measured for impairment. Allowable methods for determining the amount of impairment include estimating fair value using the fair value of the collateral for collateral-dependent loans. If the impaired loan is identified as collateral-dependent, the fair value method of measuring the amount of impairment is utilized. This method requires obtaining a current independent appraisal of the collateral and applying a discount factor to the value. Impaired loans that are collateral-dependent are classified within Level 3 of the fair value hierarchy when impairment is determined using the fair value method. The fair value of impaired loans with specific allocated losses was $1.9 million and $1.4 million at December 31, 2019 and 2018, respectively. Non-Financial Assets

Such shares or units are considered participating securities (i.e., nonvested restricted stock grants). Additionally, for period prior to June 30, 2018, Series D preferred stockholders were participating stockholders as those shares participate in dividends with common shares on a one for one basis. Net income allocated to participating stockholders does not include dividends paid to preferred stockholders. (2) The average participating share count for the calculation of earnings per share for the year ended December 31, 2018, includes an allocation for Series D preferred stockholders, which were converted to common stock during the quarter ended June 30, 2018.

Recorded Investment in Loans by Credit Quality Indicator	The following is a summary description of the Company's internal risk ratings: • Pass (1-6) Loans within this risk rating are further categorized as follows: Minimal risk (1) Well-collateralized by cash equivalent instruments held by the Bank. Moderate risk (2) Borrowers with excellent asset quality and liquidity. Borrowers' capitalization and liquidity exceed industry norms. Borrowers in this category have significant levels of liquid assets and have a low level of leverage. Better than average risk (3) Borrowers with strong financial strength and excellent liquidity that consistently demonstrate strong operating performance. Borrowers in this category generally have a sizable net worth that can be converted into liquid assets within 12 months. Average risk (4) Borrowers with sound credit quality and financial performance, including liquidity. Borrowers are supported by sufficient cash flow coverage generated through operations across the full business cycle. Marginally acceptable risk (5) Loans generally meet minimum requirements for an acceptable loan in accordance with lending policy, but possess one or more attributes that cause the overall risk profile to be higher than the majority of newly approved loans. Watch (6) A passing loan with one or more factors that identify a potential weakness in the overall ability of the borrower to repay the loan. These weaknesses are generally mitigated by other factors that reduce the risk of delinquency or loss. • Special Mention (7) This grade is intended to be temporary and includes borrowers whose credit quality have deteriorated and is at risk of further decline. • Substandard (8) This grade includes "Substandard" loans under regulatory guidelines. Substandard loans exhibit a well-defined weakness that jeopardizes debt repayment in accordance with contractual agreements, even though the loan may be performing. These obligations are characterized by the distinct possibility that a loss may be incurred if these weaknesses are not corrected and repayment may be dependent upon collateral liquidation or secondary source of repayment. • Doubtful (9) This grade includes "Doubtful" loans under regulatory guidelines. Such loans are placed on nonaccrual status and repayment may be dependent upon collateral with no readily determinable valuation or valuations that are highly subjective in nature. Repayment for these loans is considered improbable based on currently existing facts and circumstances. • Loss (0) This grade includes "Loss" loans under regulatory guidelines. Loss loans are charged-off or written down when repayment is not expected. Loans held for investment by credit quality indicator at December 31, 2019 and 2018 , were as follows: (Dollars in thousands) December 31, 2019 Loans secured by real estate: Pass Special Mention Substandard Doubtful Loss Total Commercial real estate $ 1,269,493 $ 12,479 $ 14,875 $ — $ — $ 1,296,847 Construction/land/land development 512,901 149 4,638 — — 517,688 Residential real estate 680,046 1,558 7,951 — — 689,555 Total real estate 2,462,440 14,186 27,464 — — 2,504,090 Commercial and industrial 1,277,564 28,478 37,433 — — 1,343,475 Mortgage warehouse lines of credit 274,659 — — — — 274,659 Consumer 20,808 — 163 — — 20,971 Total loans held for investment $ 4,035,471 $ 42,664 $ 65,060 $ — $ — $ 4,143,195 (Dollars in thousands) December 31, 2018 Loans secured by real estate: Pass Special Mention Substandard Doubtful Loss Total Commercial real estate $ 1,206,194 $ 3,101 $ 19,107 $ — $ — $ 1,228,402 Construction/land/land development 426,770 157 2,733 — — 429,660 Residential real estate 617,996 1,142 10,576 — — 629,714 Total real estate 2,250,960 4,400 32,416 — — 2,287,776 Commercial and industrial 1,190,718 34,964 46,884 — — 1,272,566 Mortgage warehouse lines of credit 207,871 — — — — 207,871 Consumer 20,712 — 180 — — 20,892 Total loans held for investment $ 3,670,261 $ 39,364 $ 79,480 $ — $ — $ 3,789,105

The ASU was issued by the FASB in February 2018, to address the issue of other comprehensive income or loss that became stranded in AOCI as a result of the re-measurement of an entity's deferred income tax assets and liabilities following the reduction of the U.S. federal corporate tax rate from 35% to 21% pursuant to the enactment of the Tax Cuts and Jobs Act in December 2017. The Company also had certain current tax amounts stranded in AOCI that resulted from a tax accounting election to tax net gains and losses on AFS securities and cash flow hedges as current items beginning in 2016. The Company reclassifies the taxes from AOCI to earnings as the individual securities and hedges are realized. Due to the change in corporate tax rates, the Company had certain net gains and losses taxed at the 35% rate reflected in AOCI. As these transactions are realized over time, they will flow through income tax expense at the 21% rate. Rather than adjusting income tax expense for the difference as each of these securities and instruments are realized, the Company elected to adjust the difference (stranded tax effect) to retained earnings, consistent with the treatment of the deferred tax adjustment.
