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 44 banking centers located in Dallas/Fort Worth and Houston, Texas, North Louisiana and into Mississippi. 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 . The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions based on available information that affect the amounts reported in the financial statements and disclosures provided, including the accompanying notes, and actual results could differ. Material estimates that are particularly susceptible to change include the allowance for credit losses for loans and available for sale securities; fair value measurements of assets and liabilities; and income taxes. Estimates and assumptions are reviewed periodically and the effects of revisions are reflected in the Company's consolidated financial statements in the period they are deemed necessary. While management uses its best judgment, 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, 2020 and 2019 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, 2020 and 2019 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 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. Unrealized gains and losses on AFS securities are excluded from earnings and reported net of tax in accumulated other comprehensive income until realized. Please see the paragraphs under Allowance for Credit Losses referenced below in this footnote for information on the allowance for credit losses pertaining to AFS securities. 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 unaccredited discounts. Please see the paragraphs under Allowance for Credit Losses referenced below in this footnote for information pertaining to the allowance for credit losses pertaining to HTM securities. 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. Interest income on securities includes amortization of purchase premiums and discounts. Premiums and discounts on securities are generally amortized using the interest method with a constant effective yield without anticipating prepayments, except for mortgage-backed securities where prepayments are anticipated. Premiums on callable securities are amortized to their earliest call date. A security is placed on nonaccrual status if (i) principal or interest has been in default for a period of 90 days or more or (ii) full payment of principal and interest is not expected. Interest accrued but not received for a security placed on nonaccrual status is reversed against interest income. Gains and losses on sales are recorded on the trade date, are derived from the amortized cost of the security sold and are determined using the specific identification method. Prior to the adoption of ASU 2016-13, declines in the fair value of held-to-maturity and available-for-sale securities below their cost that were deemed to be other than temporary were reflected in earnings as realized losses. In estimating other-than-temporary impairment losses prior to January 1, 2020, management considered, among other things, (i) the length of time and the extent to which the fair value had been less than cost, (ii) the financial condition and near-term prospects of the issuer and (iii) the intent and our ability to retain our investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value. 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, excluding FRB and FHLB, totaling $12.1 million at December 31, 2020 and 2019, 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, 2020, 2019 and 2018. 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 credit 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 LHFI, 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 credit 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 Credit Losses . The allowance for loan credit losses represents the estimated losses for financial assets accounted for on an amortized cost basis. Expected losses are calculated using relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. The Company evaluates loans held for investment ("LHFI") on a pool basis with pools of loans characterized by loan type, collateral, industry, internal credit risk rating and Fair Isaac Corporation ("FICO") score. The Company applied a probability of default, loss given default loss methodology to the loan pools at January 1 and December 31, 2020. Historical loss rates for each pool are calculated based on charge-off and recovery data beginning with the second quarter of 2012. These loss rates are adjusted for differences between current period conditions, including the ongoing effects of COVID-19 on the U.S. economy, and the conditions existing during the historical loss period. Historical losses are additionally adjusted for the effects of certain economic variables forecast over a one-year period. Subsequent to the forecast effects, historical loss rates are used to estimate losses over the estimated remaining lives of the loans. The estimated remaining lives consist of the contractual lives, adjusted for estimated prepayments. Loans that exhibit characteristics different from their pool characteristics are evaluated on an individual basis. Certain of these loans are considered to be collateral dependent with the borrower experiencing financial difficulty. For these loans, the fair value of collateral practical expedient is elected whereby the allowance is calculated as the amount by which the amortized cost exceeds the fair value of collateral, less costs to sell (if applicable). Those individual loans that are not collateral dependent are evaluated based on a discounted cash flow methodology. 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 credit losses when management believes the loss is confirmed. Subsequent recoveries, if any, are credited to the allowance. Prior to the adoption of ASU 2016-13, the allowance for credit losses on loans was established through a provision for loan losses charged to expense, which represented management’s best estimate of inherent losses that had been incurred within the existing portfolio of loans. The allowance for credit losses on loans included allowance allocations calculated in accordance with ASC Topic 310, “Receivables” and allowance allocations calculated in accordance with ASC Topic 450, “Contingencies.” 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 credit losses. Internal risk ratings are updated on a regular basis. Prior to the adoption of ASC 326 on January 1, 2020, loans were reported as impaired when, based on then current information and events, it was probable that the Company would be unable to collect all amounts due in accordance with the original contractual terms of the loan agreement, including scheduled principal and interest payments. Impairment was evaluated in total for smaller-balance loans of a similar nature and on an individual loan basis for other loans. If a loan was impaired, a specific valuation allowance was allocated, if necessary, so that the loan was reported net, at the present value of estimated future cash flows using the loan’s existing rate or at the fair value of collateral if repayment was expected solely from the collateral. Interest payments on impaired loans were typically applied to principal unless collectibility of the principal amount was reasonably assured, in which case interest was recognized on a cash basis. Impaired loans, or portions thereof, were charged off when deemed uncollectible. Troubled debt restructurings ("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. Certain borrowers are currently unable to meet their contractual payment obligations because of the adverse effects of COVID-19. To help mitigate these effects, loan customers may apply for a deferral of payments, or portions thereof, for up to 90 days. The CARES Act and related guidance from the federal banking agencies provide financial institutions the option to temporarily suspend requirements under GAAP related to classification of certain loan modifications as TDRs to account for the current and anticipated effects of COVID-19. The CARES Act, as amended by the Consolidated Appropriations Act, 2021, specified that COVID-19 related loan modifications executed between March 1, 2020 and the earlier of (i) 60 days after the date of termination of the national emergency declared by the President and (ii) January 1, 2022, on loans that were current as of December 31, 2019 are not TDRs. Additionally, under guidance from the federal banking agencies, other short-term modifications made on a good faith in response to COVID-19 to borrowers that were current prior to any relief are not TDRs under ASC Subtopic 310-40, “Troubled Debt Restructuring by Creditors.” These modifications include short-term (e.g., up to six months) modifications such as payment deferrals, fee waivers, extensions of repayment terms, or delays in payment that are insignificant. At December 31, 2020, the Company had 49 loans totaling $97.7 million under COVID-19 related forbearance agreements. The allowance for off-balance sheet exposures was determined using the same methodology that is applied to LHFI. Utilization rates are determined based on historical usage. Credit losses related to available for sale debt securities are recorded through an allowance for credit losses. The amount of the allowance for credit losses is limited to the amount by which fair value is below amortized cost. Discounted cash flow analysis is required for determining credit losses for available for sale securities. In determining whether or not a credit loss exists, such factors as extent of the loss, adverse conditions related to the entity, industry or geographic region, security structure, ratings and changes by a rating agency and past performance are considered. The length of time a security has been in an unrealized loss position is not a factor in determining whether a credit loss exists. The allowance for credit losses for held-to-maturity securities is calculated using a probability of default, loss given default methodology. Credit losses are estimated over the lives of the securities using historical loss rates, adjusted for current conditions and reasonable and supportable forecasts. Third party data is used for the historical loss rates and probability of default statistics. Additionally, the Company uses a weighted average of three possible economic scenarios derived from third party data which is used to calculate the forecast effect. The forecast effect is applied over the estimated lives of the securities. 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 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. 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 a financial institution 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 institution intends to exercise the buy-back option. These loans were recorded as mortgage loans held for sale, at the lower of cost or fair value with a corresponding liability in FHLB advances and other borrowings on the Company's consolidated balance sheets. 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 typically October 1 for the Company, or more often if events or circumstances indicate that there may be impairment. Because of the volatile market conditions during which the Company's market value fell below book value, the Company performed a qualitative assessment of whether it was more likely than not that the fair value was less than carrying value during each quarter of 2020 including a goodwill impairment assessment performed by a third party valuation specialist during the second quarter of 2020. Based on these assessments, it was determined that the Company's fair value exceeded carrying value and no goodwill impairment was recorded during 2020. 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 credit 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, 2020 and 2019, the balance of OREO was $1.6 million and $4.7 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. Revenue Recognition . In general, for revenue not associated with financial instruments, guarantees and lease contracts, the Company applies the following steps when recognizing revenue from contracts with customers: (i) identify the contract, (ii) identify the performance obligations, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations and (v) recognize revenue when a performance obligation is satisfied. Our contracts with customers are generally short term in nature, typically due within one year or less or cancellable by us or our customer upon a short notice period. Performance obligations for our customer contracts are generally satisfied at a single point in time, typically when the transaction is complete, or over time. Descripti

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. (3) Net income available to common stockholders for basic and diluted earnings per share may differ under the two-class method as a result of adding common stock equivalents for options to dilutive shares outstanding, which alters the ratio used to allocate earnings to common stockholders and participating securities for the purposes of calculating diluted earnings per share. (4) Due to the combined impact of the repurchase of common stock on the quarterly average common shares outstanding calculation compared to the impact of the repurchase of common stock on the year-to-date average common shares outstanding calculation, and the effect of rounding, the sum of the quarterly earnings per common share may not equal the year-to-date earnings per common share amount.

Consideration is given to (1) the extent to which the fair value is less than cost, (2) the financial condition and near-term prospects of the issuer, and (3) the intent and ability of the Company to retain its investment in the security for a period of time sufficient to allow for any anticipated recovery in fair value. At December 31, 2020, the Company had 44 available for sale debt securities in an unrealized loss position without an allowance for credit losses. Management does not have the intent to sell any of these securities and believes that it is more likely than not that the Company will not have to sell any such securities before a recovery of cost. The fair value is expected to recover as the securities approach their maturity date or repricing date or if market yields for such investments decline. Accordingly, at December 31, 2020, management believes that the unrealized losses detailed in the previous table are due to noncredit-related factors, including changes in interest rates and other market conditions, and therefore no losses have been recognized in the Company’s consolidated statements of income. The following table presents the activity in the allowance for credit losses for held-to-maturity debt securities.

No PPP loans were outstanding at December 31, 2019. (2) Includes net deferred loan fees of $13.7 million and $3.6 million at December 31, 2020, and December 31, 2019, respectively. Origination of PPP loans contributed $9.6 million of the increase in net deferred loan fees during the year. Included in total LHFI were $17.0 million and $17.7 million of commercial real estate loans for which the fair value option was elected at December 31, 2020 and 2019, 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. The Company has been a participating lender in the PPP. At December 31, 2020, there were approximately $546.5 million in PPP loans outstanding included in the Company’s commercial and industrial loan portfolio, net of $9.6 million in net deferred loan fees. PPP loans have a maximum maturity of two years and earn interest at 1%. PPP loans are fully guaranteed by the U.S. government and can be forgiven by the SBA if the borrower uses the proceeds to pay specified expenses. The Company believes that the majority of our PPP loans will ultimately be forgiven by the SBA in accordance with the terms of the program. 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 (defined as substandard, doubtful and loss), 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. In connection with the review of the loan portfolio, the Company considers risk elements attributable to particular loan types or categories in assessing the quality of individual loans. The list of loans to be reviewed for possible individual evaluation consists of nonaccrual commercial loans over $100,000 with direct exposure, unsecured loans over 90 days past due, commercial loans classified substandard or worse over $100,000 with direct exposure, TDRs, consumer loans greater than $100,000 with a FICO score under 625, loans greater than $100,000 in which the borrower has filed bankruptcy, and all loans 180 days or more past due. Loans under $50,000 will be evaluated collectively in designated pools unless a loss exposure has been identified. Some additional risk elements considered by loan type include: • for commercial real estate loans, the debt service coverage ratio, operating results of the owner in the case of owner occupied properties, the loan to value ratio, the age and condition of the collateral and the volatility of income, property value and future operating results typical of properties of that type; • for construction, land and land development loans, the perceived feasibility of the project, including the ability to sell developed lots or improvements constructed for resale or the ability to lease property constructed for lease, the quality and nature of contracts for presale or prelease, if any, experience and ability of the developer and loan to value ratio; • for residential mortgage loans, the borrower's ability to repay the loan, including a consideration of the debt to income ratio and employment and income stability, the loan-to-value ratio, and the age, condition and marketability of the collateral; and • for commercial and industrial loans, the debt service coverage ratio (income from the business in excess of operating expenses compared to loan repayment requirements), the operating results of the commercial, industrial or professional enterprise, the borrower's business, professional and financial ability and expertise, the specific risks and volatility of income and operating results typical for businesses in that category and the value, nature and marketability of collateral. The following table reflects recorded investments in loans by credit quality indicator and origination year at December 31, 2020, excluding loans held for sale and loans accounted for at fair value. The Company had an immaterial amount of revolving loans converted to term loans at December 31, 2020.

The provision for loan credit losses for the year ended December 31, 2020, was driven by the continuing uncertainty related to the ongoing economic impact and duration of the current COVID-19 pandemic. Based upon the requirements of CECL, economic forecasts are essential for estimating the life of loan losses. The increased risk, as reflected in current and forecast adjustments, resulted in approximately $39.8 million in provision expense in total collective reserves, of which $27.5 million was related to qualitative factor changes, across the Company’s risk pools for the year ended December 31, 2020. An additional $8.1 million in provision expense was due to the current and forecast effects of individually evaluated loans. There were four significant loan charge-offs during year ended December 31, 2020, totaling $6.6 million reflecting two loan relationships.

All fair value of collateral is real estate related. Collateral-dependent loans consist primarily of commercial real estate and commercial and industrial loans. These loans are individually evaluated when foreclosure is probable or when the repayment of the loan is expected to be provided substantially through the operation or sale of the underlying collateral. Loan balances are charged down to the underlying collateral value when they are deemed uncollectible. Nonaccrual LHFI were as follows: December 31, 2020 2019 (Dollars in thousands) Nonaccrual With No Allowance for Credit Loss Nonaccrual Nonaccrual Loans secured by real estate: Commercial real estate $ 1,053 $ 3,704 $ 6,994 Construction/land/land development 1,319 2,962 4,337 Residential real estate 2,436 6,530 5,132 Total real estate 4,808 13,196 16,463 Commercial and industrial 82 12,897 14,520 Consumer — 56 163 Total nonaccrual loans $ 4,890 $ 26,149 $ 31,146 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. At December 31, 2020, the Company had no funding commitments the terms of which have been modified in TDRs. For the years ended December 31, 2020, 2019 and 2018, gross interest income that would have been recorded had the nonaccruing loans been current in accordance with their original terms was $1.5 million, $1.5 million and $1.4 million, respectively. No interest income was recorded on these loans while they were considered nonaccrual during the years ended December 31, 2020, 2019 or 2018. The Company elects the fair value option for recording residential mortgage loans held for sale, as well as certain commercial real estate in accordance with U.S. GAAP. The Company had $681,000 of nonaccrual mortgage loans held for sale that were recorded using the fair value option election at December 31, 2020, compared to $927,000 at December 31, 2019. There were no nonaccrual LHFI that were recorded using the fair value option election at December 31, 2020, or December 31, 2019. Certain borrowers are currently unable to meet their contractual payment obligations because of the adverse effects of COVID-19. To help mitigate these effects, loan customers may apply for a deferral of payments, or portions thereof, for up to 90 days. The CARES Act and related guidance from the federal banking agencies provide financial institutions the option to temporarily suspend requirements under GAAP related to classification of certain loan modifications as TDRs to account for the current and anticipated effects of COVID-19. The CARES Act, as amended by the Consolidated Appropriations Act, 2021, specified that COVID-19 related loan modifications executed between March 1, 2020 and the earlier of (i) 60 days after the date of termination of the national emergency declared by the President and (ii) January 1, 2022, on loans that were current as of December 31, 2019 are not TDRs. Additionally, under guidance from the federal banking agencies, other short-term modifications made on a good faith basis in response to COVID-19 to borrowers that were current prior to any relief are not TDRs under ASC Subtopic 310-40, “Troubled Debt Restructuring by Creditors.” These modifications include short-term (e.g., up to six months) modifications such as payment deferrals, fee waivers, extensions of repayment terms, or delays in payment that are insignificant. At December 31, 2020, the Company had 49 loans totaling $97.7 million under COVID-19 related forbearance agreements that were not treated as TDRs pursuant to the CARES Act and interagency guidance. Loans classified as TDRs, excluding the impact of forbearances granted due to COVID-19, were as follows: (Dollars in thousands) December 31, TDRs 2020 2019 Nonaccrual TDRs $ 5,671 $ 6,609 Performing TDRs 3,314 1,843 Total $ 8,985 $ 8,452 The tables below summarize loans classified as TDR's by loan and concession type.

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. Fair Values of Assets and Liabilities Recorded on a Recurring Basis The following tables summarize financial assets and financial liabilities recorded at fair value on a recurring basis at December 31, 2020 and 2019, segregated by the level of valuation inputs within the fair value hierarchy utilized to measure fair value. There were no changes in the valuation techniques during 2020 or 2019.

The Company obtains fair value measurements for loans at fair value, securities available for sale and securities at fair value through income from an independent pricing service, therefore, quantitative unobservable inputs are unknown. 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, 2020 December 31, 2019 Range Weighted Average (1) Weighted Average (1) Prepayment speeds 11.82% - 37.95% 22.08 % 12.46 % Discount rates 7.83 - 9.09 8.27 9.55 __________________________ (1) The weighted average was calculated with reference to the principle balance of the underlying mortgages. In recent years, there have been significant market-driven fluctuations in the assumptions listed above. Loans with higher average coupon rates have a greater likelihood of prepayment during the current interest rate environment, while loans with lower average coupon rates have a lower likelihood of prepayment. The decline in rates during the year ended December 31, 2020, has caused an increase in our weighted average prepayment speed assumptions used in the MSR valuation. 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, 2020 and 2019, 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, 2020 (Dollars in thousands) Aggregate Fair Value Aggregate Unpaid Principal Balance Difference Loans held for sale (1) $ 136,026 $ 129,955 $ 6,071 Commercial real estate LHFI (2) 17,011 16,760 251 Securities carried at fair value through income 11,554 10,618 936 Total $ 164,591 $ 157,333 $ 7,258 ____________________________ (1) $681,000 of loans held for sale were designated as nonaccrual or 90 days or more past due at December 31, 2020. Of this balance, $473,000 was guaranteed by U.S. Government agencies. (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, 2020. 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 LHFI (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, $709,000 was guaranteed by U.S. Government agencies. (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. 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: 2020 2019 2018 Mortgage banking revenue $ 5,131 $ 550 $ (163) Other income: Loans at fair value held for investment (53) 124 (389) Securities carried at fair value through income 493 586 (258) Total impact on other income 440 710 (647) Total fair value option impact on noninterest income (1) $ 5,571 $ 1,260 $ (810) ____________________________ (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, 2020 and 2019. 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. LHFI For LHFI 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 both December 31, 2020 and 2019. 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 $62.6 million and $39.8 million, at December 31, 2020 and 2019, respectively, 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 $55.5 million and $27.9 million, respectively, at December 31, 2020 and 2019, 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 Loans with Credit Losses Loans for which it is probable that the Company will not collect all principal and interest due according to contractual terms are measured to determine if any credit loss exists. Allowable methods for determining the amount of credit loss includes estimating the fair value using the fair value of the collateral for collateral-dependent loans. If the loan is identified as collateral-dependent, the fair value method of measuring the amount of credit loss is utilized. This method requires obtaining a current independent appraisal of the collateral and applying a discount factor to the value. Loans that have experienced a credit loss that are collateral-dependent are classified within Level 3 of the fair value hierarchy when the credit loss is determined using the fair value method. The fair value of loans that have experienced a credit loss with specific allocated losses was approximately $12.3 million and $1.9 million at December 31, 2020, and December 31, 2019, 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 credit 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 $1.6 million and $4.7 million at December 31, 2020 and 2019, respectively. At December 31, 2020, the Company had no residential mortgage loans in the process of foreclosure. Fair Values of Financial Instruments Not Recorded at Fair Value Loans The estimated fair value approximates carrying value for variable-rate loans that reprice frequently and with no significant change in credit risk. The fair value of fixed-rate loans and variable-rate loans which reprice on an infrequent basis is estimated by discounting future cash flows using exit level pricing, which combines the current interest rates at which similar loans with similar terms would be made to borrowers of similar credit quality and an estimated additional rate to reflect a liquidity premium. An overall valuation adjustment is made for specific credit risks as well as general portfolio credit risk. Deposits The estimated fair value approximates carrying value for demand deposits. The fair value of fixed-rate deposit liabilities with defined maturities is estimated by discounting future cash flows using the interest rates currently available for funding from the FHLB. The estimated fair value of deposits does not take into account the value of our long-term relationships with depositors, commonly known as core deposit intangibles, which are separate intangible assets, and not considered financial instruments. Nonetheless, the Company would likely realize a core deposit premium if the deposit portfolio were sold in the principal market for such deposits. Borrowed Funds The estimated fair value approximates carrying value for short-term borrowings. The fair value of long-term fixed-rate and fixed-to-floating-rate borrowings is estimated using quoted market prices, if available, or by discounting future cash flows using current interest rates for similar financial instruments. The estimated fair value approximates carrying value for variable-rate junior subordinated debentures that reprice quarterly. 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: 2020 2019 Level 1 inputs: Carrying Estimated Carrying Estimated Cash and cash equivalents $ 377,214 $ 377,214 $ 291,518 $ 291,518 Level 2 inputs: Non-marketable equity securities held in other financial institutions 62,586 62,586 39,808 39,808 Accrued interest and loan fees receivable 27,146 27,146 16,430 16,430 Level 3 inputs: Securities held to maturity 38,128 41,205 28,620 29,523 LHFI, net (1) 5,621,092 5,802,744 4,088,005 3,940,347 Financial liabilities: Level 2 inputs: Deposits 5,751,315 5,756,312 4,228,612 4,081,430 FHLB advances and other borrowings 984,608 991,943 417,190 425,318 Subordinated debentures 157,181 156,395 9,671 10,717 Accrued interest payable 3,556 3,556 2,822 2,822 ____________________________ (1) Does not include loans for which the fair value option had been elected at December 31, 2020 or 2019, as these loans are carried at fair value on a recurring basis.

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) 2020 2019 2018 Balance at beginning of period $ 20,697 $ 25,114 $ 24,182 Addition of servicing rights 5,709 2,595 1,895 Valuation adjustment, net of amortization (12,746) (7,012) (963) Balance at end of period $ 13,660 $ 20,697 $ 25,114 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 violated representations or warranties made by the Company and/or the borrower 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 $82,000 in mortgage loan servicing putback reserve expense for the year ended December 31, 2020, and $33,000 for the year ended December 31, 2019. The Company incurred no mortgage loan servicing putback reserve expense for the year ended December 31, 2018. At December 31, 2020 and 2019, the reserve for mortgage loan servicing putback expenses totaled $311,000 and $229,000, 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.

The Company also had a $75.0 million secured repurchase line of credit at December 31, 2020 and 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 0.22% and 1.20% for the years ended December 31, 2020 and 2019, respectively. Long-Term Borrowings Interest rates for FHLB long-term advances outstanding at both December 31, 2020 and 2019, ranged from 1.65% to 5.72%, respectively. 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, 2020, are as follows: (Dollars in thousands) Years Ended December 31, 2021 $ 1,090 2022 2,404 2023 4,043 2024 3,020 2025 1,641 Thereafter (1) 258,517 Total $ 270,715 __________________________ (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 at December 31, 2020 and 2019, were $456.9 million and $601.9 million, respectively. Additionally, at December 31, 2020 and December 31, 2019, the Company had the availability to borrow $793.2 million and $855.1 million, respectively, from the discount window at the Federal Reserve Bank of Dallas, with $999.7 million and $1.09 billion in commercial and industrial loans pledged as collateral, respectively. There were no borrowings against this line at December 31, 2020 or 2019. 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 at December 31, 2020 or 2019. Subordinated Debentures In February 2020, Origin Bank completed an offering of $70.0 million in aggregate principal amount of 4.25% fixed-to-floating rate subordinated notes due 2030 (the “Notes”) to certain investors in a transaction exempt from registration under Section 3(a)(2) of the Securities Act of 1933, as amended. The Notes initially bear interest at a fixed annual rate of 4.25%, payable semi-annually in arrears, to but excluding February 15, 2025. From and including February 15, 2025, to but excluding the maturity date or early redemption date, the interest rate will equal the three-month LIBOR rate (provided, that in the event the three-month LIBOR is less than zero, the three-month LIBOR will be deemed to be zero) plus 282 basis points, payable quarterly in arrears. Origin Bank is entitled to redeem the Notes, in whole or in part, on or after February 15, 2025, and to redeem the Notes at any time in whole upon certain other specified events. The Notes qualify as Tier 2 capital for regulatory capital purposes for Origin Bank. In October 2020, the Company completed of an offering of $80.0 million in aggregate principal amount of 4.50% fixed-to-floating rate subordinated notes due 2030 (the “4.50% Notes”). The 4.50% Notes bear a fixed interest rate of 4.50% payable semi-annually in arrears, to but excluding November 1, 2025. From and including November 1, 2025, to but excluding the maturity date or earlier redemption date, the 4.50% Notes bear a floating interest rate expected to equal the three-month term Secured Overnight Financing Rate plus 432 basis points, payable quarterly in arrears. The Company may redeem the 4.50% Notes at any time upon certain specified events or in whole or in part on or after November 1, 2025. The 4.50% Notes qualify as Tier 2 capital for regulatory capital purposes for the Company and $51.0 million was transferred to Origin Bank during the fourth quarter of 2020, which qualifies as Tier 1 capital for regulatory capital purposes for the Bank. The 4.50% Notes provided net proceeds to the Company of approximately $78.6 million. 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 and can be currently redeemed by the Company in whole or in part, at a redemption price specified in the indentures 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 junior subordinated debentures at December 31, 2020: (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) 3.51 % 12.50 % First Louisiana Statutory Trust I 09/2006 12/2036 4,124 Variable (2) 2.02 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, 2020. (2) The trust preferred securities reprice quarterly based on the three-month LIBOR plus 1.80%, with the last reprice date on December 11, 2020. The balance of the junior subordinated debentures outstanding varies from the amounts carried on the consolidated balance sheets due to the remaining purchase discount of $1.1 million and $1.2 million, at December 31, 2020, and December 31, 2019, respectively, which was established at the time of issuance and 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. From time to time, the Company shares in credit risk on interest rate swap arrangements, by entering into risk participation agreements with syndication partners. These are accounted for at fair value and disclosed as risk participation derivatives. 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, 2020 and 2019, as well as the effect of these derivative instruments on the Company's consolidated statements of income for the years ended December 31, 2020, 2019 and 2018: Notional Amounts (1) Fair Values (Dollars in thousands) December 31, December 31, Derivatives designated as cash flow hedging instruments: 2020 2019 2020 2019 Interest rate swaps included in other (liabilities) $ 21,000 $ 10,500 $ (706) $ (101) Derivatives not designated as hedging instruments: Interest rate swaps included in other assets $ 326,542 $ 217,633 $ 20,207 $ 8,425 Interest rate swaps included in other liabilities 347,096 246,397 (21,321) (9,278) Risk participation derivative included in accrued expenses and other liabilities on the consolidated balance sheets 63,374 — (18) — Forward commitments to purchase mortgage-backed securities included in other (liabilities) assets 107,000 200,000 (317) 242 Forward commitments to sell residential mortgage loans included in other liabilities 107,200 60,600 (658) (109) Interest rate-lock commitments on residential mortgage loans included in other assets 79,554 37,382 3,487 717 $ 1,030,766 $ 762,012 $ 1,380 $ (3) ____________________________ (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, 2020 and 2019, were as follows: Weighted-Average Interest Rate December 31, 2020 2019 Interest rate swaps: Paid Received Paid Received Cash flow hedges 4.81 % 2.94 % 4.81 % 4.64 % Non-hedging interest rate swaps - financial institution counterparties 4.18 2.48 4.93 4.13 Non-hedging interest rate swaps - customer counterparties 2.52 4.19 4.18 4.93 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: 2020 2019 2018 Amount of gain (loss) recognized in mortgage banking revenue (1) $ 4,081 $ 3,079 $ (2,450) Amount of (loss) gain recognized in other non-interest income (307) (530) 584 ____________________________ (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.

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, 2020. 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 incentive stock options, non-qualified stock options, stock appreciation rights, restricted stock awards, restricted stock units, dividend equivalent rights, performance unit awards or any combination thereof. At December 31, 2020, the maximum number of shares of the Company's common stock available for issuance under the 2012 Plan was 921,248 shares. Share-based compensation cost charged to income for the years ended December 31, 2020, 2019 and 2018, is presented below. There was no stock option expense for any of the periods shown.

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. At December 31, 2020, there was $2.3 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 1.9 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, 2020, 2019 and 2018.

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, 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 $2.0 million, $1.8 million and $1.6 million for the years ended December 31, 2020, 2019 and 2018, respectively.

The deferred compensation liability was $11.3 million and $9.8 million at December 31, 2020 and 2019, respectively. The expense recorded for the deferred compensation plan totaled $1.9 million, $1.2 million, and $1.1 million for the years ended December 31, 2020, 2019 and 2018, respectively.

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 $994,000 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 2017.

Accumulated Other Comprehensive Income	Note 16 - Accumulated Other Comprehensive Income Accumulated other comprehensive income ("AOCI") includes the after-tax change in unrealized gains and losses on AFS securities and cash flow hedging activities. (Dollars in thousands) Unrealized Gains (Losses) on AFS Securities Unrealized Gains (Losses) on Cash Flow Hedges Accumulated Other Comprehensive Income Balance at January 1, 2018 $ 1,280 $ 27 $ 1,307 Net change (4,157) 88 (4,069) Reclassification of tax effects related to the adoption of ASU 2018-02 (1) : Current (293) 17 (276) Deferred 569 (11) 558 Balance at January 1, 2019 (2,601) 121 (2,480) Net change 9,013 (200) 8,813 Balance at December 31, 2019 6,412 (79) 6,333 Net change 19,794 (478) 19,316 Balance at December 31, 2020 $ 26,206 $ (557) $ 25,649 ____________________________ (1) 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.

Capital and Regulatory Matters

Capital and Regulatory Matters	12 Months Ended

Banking Regulation [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, common equity Tier 1 capital, Tier 1 capital, Tier 1 capital, and total 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, 2020 and 2019, that the Company and the Bank met all capital adequacy requirements to which they are subject, including the capital buffer requirement. At December 31, 2020 and 2019, 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, common equity Tier 1 capital, Tier 1 risk based and Tier 1 leverage ratios as set forth in the table below. A final rule adopted by the federal banking agencies in February 2019 provides banking organizations with the option to phase in, over a three-year period, the adverse day-one regulatory capital effects of the adoption of CECL. In addition, on March 27, 2020, the federal banking agencies issued an interim final rule that gives banking organizations that implement CECL before the end of 2020 the option to delay for two years CECL’s adverse effects on regulatory capital. Origin elected to adopt CECL in the first quarter of 2020 and exercised the option to delay the estimated impact of the adoption of CECL on our regulatory capital for two years (from January 2020 through December 31, 2021), which resulted in a 19 basis point benefit to the common equity Tier 1 capital to risk-weighted assets capital ratio at December 31, 2020. The two-year delay will be followed by the three-year transition period of CECL's initial impact on our regulatory capital (from January 1, 2022 through December 31, 2024). The actual capital amounts and ratios of the Company and Bank at December 31, 2020 and 2019, are presented in the following table: (Dollars in thousands) December 31, 2020 Actual Minimum Capital Required - Basel III To be Well Capitalized Under Prompt Corrective Action Provisions Common Equity Tier 1 Capital to Risk-Weighted Assets Amount Ratio Amount Ratio Amount Ratio Origin Bancorp, Inc. $ 604,306 9.95 % $ 425,012 7.00 % N/A N/A Origin Bank 637,863 10.53 424,010 7.00 $ 393,724 6.50 % Tier 1 Capital to Risk-Weighted Assets Origin Bancorp, Inc. 613,682 10.11 516,107 8.50 N/A N/A Origin Bank 637,863 10.53 514,870 8.50 484,583 8.00 Total Capital to Risk-Weighted Assets Origin Bancorp, Inc. 837,058 13.79 637,539 10.50 N/A N/A Origin Bank 782,503 12.92 636,019 10.50 605,732 10.00 Leverage Ratio Origin Bancorp, Inc. 613,682 8.62 284,771 4.00 N/A N/A Origin Bank 637,863 8.99 283,842 4.00 354,802 5.00 December 31, 2019 Common Equity Tier 1 Capital to Risk-Weighted Assets Origin Bancorp, Inc. 561,630 11.74 334,785 7.00 N/A N/A Origin Bank 551,060 11.55 333,924 7.00 310,072 6.50 Tier 1 Capital to Risk-Weighted Assets Origin Bancorp, Inc. 570,975 11.94 406,524 8.50 N/A N/A Origin Bank 551,060 11.55 405,479 8.50 381,627 8.00 Total Capital to Risk-Weighted Assets Origin Bancorp, Inc. 610,305 12.76 502,175 10.50 N/A N/A Origin Bank 590,390 12.38 500,888 10.50 477,037 10.00 Leverage Ratio Origin Bancorp, Inc. 570,975 10.91 209,298 4.00 N/A N/A Origin Bank 551,060 10.56 208,774 4.00 260,968 5.00 In the ordinary course of business, the Company depends on dividends from the Bank to provide funds for the payment of dividends to stockholders and to provide for other cash requirements. 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 $60.8 million at December 31, 2020. Stock Repurchases In three transactions in March 2020, the Company repurchased a total of 30,868 shares of its common stock pursuant to its stock buyback program at an average price per share of $23.44 for an aggregate purchase price of $723,000. Prior to 2020, the Company had repurchased cumulatively $10.1 million of shares under the stock buyback program, and as of December 31, 2020, the Company's board of directors has approved approximately $29.2 million remaining shares to be purchased under the 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) 2020 2019 Commitments to extend credit $ 1,341,501 $ 1,374,055 Standby letters of credit 42,911 39,344 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, 2020 and 2019, these credit card guarantees totaled $200,000 and $489,000, 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, 2020, the Company held 35 unfunded letters of credit from the FHLB totaling $527.4 million with expiration dates ranging from January 20, 2021, to November 4, 2022. At 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. Management establishes an asset-specific allowance for certain lending-related commitments 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 $2.3 million and $1.8 million at December 31, 2020 and 2019, 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.

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 . The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions based on available information that affect the amounts reported in the financial statements and disclosures provided, including the accompanying notes, and actual results could differ. Material estimates that are particularly susceptible to change include the allowance for credit losses for loans and available for sale securities; fair value measurements of assets and liabilities; and income taxes. Estimates and assumptions are reviewed periodically and the effects of revisions are reflected in the Company's consolidated financial statements in the period they are deemed necessary. While management uses its best judgment, 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 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. Unrealized gains and losses on AFS securities are excluded from earnings and reported net of tax in accumulated other comprehensive income until realized. Please see the paragraphs under Allowance for Credit Losses referenced below in this footnote for information on the allowance for credit losses pertaining to AFS securities. 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 unaccredited discounts. Please see the paragraphs under Allowance for Credit Losses referenced below in this footnote for information pertaining to the allowance for credit losses pertaining to HTM securities. 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. Interest income on securities includes amortization of purchase premiums and discounts. Premiums and discounts on securities are generally amortized using the interest method with a constant effective yield without anticipating prepayments, except for mortgage-backed securities where prepayments are anticipated. Premiums on callable securities are amortized to their earliest call date. A security is placed on nonaccrual status if (i) principal or interest has been in default for a period of 90 days or more or (ii) full payment of principal and interest is not expected. Interest accrued but not received for a security placed on nonaccrual status is reversed against interest income. Gains and losses on sales are recorded on the trade date, are derived from the amortized cost of the security sold and are determined using the specific identification method. Prior to the adoption of ASU 2016-13, declines in the fair value of held-to-maturity and available-for-sale securities below their cost that were deemed to be other than temporary were reflected in earnings as realized losses. In estimating other-than-temporary impairment losses prior to January 1, 2020, management considered, among other things, (i) the length of time and the extent to which the fair value had been less than cost, (ii) the financial condition and near-term prospects of the issuer and (iii) the intent and our ability to retain our investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value.
Non-marketable Equity Securities Held in Other Financial Institutions	Non-marketable Equity Securities Held in Other Financial Institutions .
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.
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 credit 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 LHFI, 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 credit 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 Credit Losses . The allowance for loan credit losses represents the estimated losses for financial assets accounted for on an amortized cost basis. Expected losses are calculated using relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. The Company evaluates loans held for investment ("LHFI") on a pool basis with pools of loans characterized by loan type, collateral, industry, internal credit risk rating and Fair Isaac Corporation ("FICO") score. The Company applied a probability of default, loss given default loss methodology to the loan pools at January 1 and December 31, 2020. Historical loss rates for each pool are calculated based on charge-off and recovery data beginning with the second quarter of 2012. These loss rates are adjusted for differences between current period conditions, including the ongoing effects of COVID-19 on the U.S. economy, and the conditions existing during the historical loss period. Historical losses are additionally adjusted for the effects of certain economic variables forecast over a one-year period. Subsequent to the forecast effects, historical loss rates are used to estimate losses over the estimated remaining lives of the loans. The estimated remaining lives consist of the contractual lives, adjusted for estimated prepayments. Loans that exhibit characteristics different from their pool characteristics are evaluated on an individual basis. Certain of these loans are considered to be collateral dependent with the borrower experiencing financial difficulty. For these loans, the fair value of collateral practical expedient is elected whereby the allowance is calculated as the amount by which the amortized cost exceeds the fair value of collateral, less costs to sell (if applicable). Those individual loans that are not collateral dependent are evaluated based on a discounted cash flow methodology. 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 credit losses when management believes the loss is confirmed. Subsequent recoveries, if any, are credited to the allowance. Prior to the adoption of ASU 2016-13, the allowance for credit losses on loans was established through a provision for loan losses charged to expense, which represented management’s best estimate of inherent losses that had been incurred within the existing portfolio of loans. The allowance for credit losses on loans included allowance allocations calculated in accordance with ASC Topic 310, “Receivables” and allowance allocations calculated in accordance with ASC Topic 450, “Contingencies.” 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 credit losses. Internal risk ratings are updated on a regular basis. Prior to the adoption of ASC 326 on January 1, 2020, loans were reported as impaired when, based on then current information and events, it was probable that the Company would be unable to collect all amounts due in accordance with the original contractual terms of the loan agreement, including scheduled principal and interest payments. Impairment was evaluated in total for smaller-balance loans of a similar nature and on an individual loan basis for other loans. If a loan was impaired, a specific valuation allowance was allocated, if necessary, so that the loan was reported net, at the present value of estimated future cash flows using the loan’s existing rate or at the fair value of collateral if repayment was expected solely from the collateral. Interest payments on impaired loans were typically applied to principal unless collectibility of the principal amount was reasonably assured, in which case interest was recognized on a cash basis. Impaired loans, or portions thereof, were charged off when deemed uncollectible. Troubled debt restructurings ("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. Certain borrowers are currently unable to meet their contractual payment obligations because of the adverse effects of COVID-19. To help mitigate these effects, loan customers may apply for a deferral of payments, or portions thereof, for up to 90 days. The CARES Act and related guidance from the federal banking agencies provide financial institutions the option to temporarily suspend requirements under GAAP related to classification of certain loan modifications as TDRs to account for the current and anticipated effects of COVID-19. The CARES Act, as amended by the Consolidated Appropriations Act, 2021, specified that COVID-19 related loan modifications executed between March 1, 2020 and the earlier of (i) 60 days after the date of termination of the national emergency declared by the President and (ii) January 1, 2022, on loans that were current as of December 31, 2019 are not TDRs. Additionally, under guidance from the federal banking agencies, other short-term modifications made on a good faith in response to COVID-19 to borrowers that were current prior to any relief are not TDRs under ASC Subtopic 310-40, “Troubled Debt Restructuring by Creditors.” These modifications include short-term (e.g., up to six months) modifications such as payment deferrals, fee waivers, extensions of repayment terms, or delays in payment that are insignificant. At December 31, 2020, the Company had 49 loans totaling $97.7 million under COVID-19 related forbearance agreements. The allowance for off-balance sheet exposures was determined using the same methodology that is applied to LHFI. Utilization rates are determined based on historical usage. Credit losses related to available for sale debt securities are recorded through an allowance for credit losses. The amount of the allowance for credit losses is limited to the amount by which fair value is below amortized cost. Discounted cash flow analysis is required for determining credit losses for available for sale securities. In determining whether or not a credit loss exists, such factors as extent of the loss, adverse conditions related to the entity, industry or geographic region, security structure, ratings and changes by a rating agency and past performance are considered. The length of time a security has been in an unrealized loss position is not a factor in determining whether a credit loss exists. The allowance for credit losses for held-to-maturity securities is calculated using a probability of default, loss given default methodology. Credit losses are estimated over the lives of the securities using historical loss rates, adjusted for current conditions and reasonable and supportable forecasts. Third party data is used for the historical loss rates and probability of default statistics. Additionally, the Company uses a weighted average of three possible economic scenarios derived from third party data which is used to calculate the forecast effect. The forecast effect is applied over the estimated lives of the securities.
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
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. 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 a financial institution 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 institution intends to exercise the buy-back option. These loans were recorded as mortgage loans held for sale, at the lower of cost or fair value with a corresponding liability in FHLB advances and other borrowings on the Company's consolidated balance sheets.
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities . 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. From time to time, the Company shares in credit risk on interest rate swap arrangements, by entering into risk participation agreements with syndication partners. These are accounted for at fair value and disclosed as risk participation derivatives. 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 typically October 1 for the Company, or more often if events or circumstances indicate that there may be impairment. Because of the volatile market conditions during which the Company's market value fell below book value, the Company performed a qualitative assessment of whether it was more likely than not that the fair value was less than carrying value during each quarter of 2020 including a goodwill impairment assessment performed by a third party valuation specialist during the second quarter of 2020. Based on these assessments, it was determined that the Company's fair value exceeded carrying value and no goodwill impairment was recorded during 2020. 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.
Revenue Recognition	Revenue Recognition . In general, for revenue not associated with financial instruments, guarantees and lease contracts, the Company applies the following steps when recognizing revenue from contracts with customers: (i) identify the contract, (ii) identify the performance obligations, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations and (v) recognize revenue when a performance obligation is satisfied. Our contracts with customers are generally short term in nature, typically due within one year or less or cancellable by us or our customer upon a short notice period. Performance obligations for our customer contracts are generally satisfied at a single point in time, typically when the transaction is complete, or over time. 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.
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, 2020 and 2019.
Stock-Based Compensation	Stock-Based Compensation .
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 the years ended December 31, 2020 and 2019, 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 year ended December 31, 2018, was 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.
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. 2019-10, Financial Instruments —Credit Losses (Topic 326), the impact of this ASU alleviates step 2 of the goodwill impairment test. Implementation of this ASU became effective for the Company on January 1, 2020, and did not materially impact the consolidated financial statements or disclosures. 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 aligns 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. 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. Please see the paragraphs under Allowance for Credit Losses referenced above in this footnote for additional information on the determination of the allowance for credit losses as required by these ASUs. The Company made the following policy elections related to the adoption of the guidance in Topic 326: • Accrued interest will be written off against interest income when financial assets are placed into nonaccrual status. Therefore, accrued interest will be excluded from the amortized cost basis for purposes of calculating the allowance for credit losses. Accrued interest receivable is presented with other assets in a separate line item in the consolidated balance sheet. • The fair value of collateral practical expedient has been elected on certain loans, in determining the allowance for credit losses, for which the repayment is expected to be provided substantially through the operation or sale of the collateral when the borrower is experiencing financial difficulty. • For credit loss estimates calculated using a discounted cash flow approach, the entire change in present value is reported in credit loss expense rather than being attributed to interest income. The adoption of ASC Topic 326 was recorded on it's original effective date as a cumulative effect adjustment to retained earnings at January 1, 2020, and is shown below. (Dollars in thousands) December 31, 2019 Balance Transition Adjustment January 1, 2020 LHFI: Loans secured by real estate: Commercial real estate $ 10,013 $ (5,052) $ 4,961 Construction/land/land development 3,711 1,141 4,852 Residential real estate 6,332 (2,526) 3,806 Total real estate 20,056 (6,437) 13,619 Commercial and industrial 16,960 7,296 24,256 Mortgage warehouse lines of credit 262 29 291 Consumer 242 360 602 Total allowance for loan credit losses $ 37,520 $ 1,248 $ 38,768 Reserve for off-balance sheet exposures $ 1,810 $ (381) $ 1,429 Held-to-Maturity Securities: Municipal securities $ — $ 96 $ 96 ASU No. 2018-13, Fair Value Measurement - (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement modifies the disclosure requirements on fair value measurements in Topic 820.

ASU 2018-13 became effective for us on January 1, 2020, and did not have a significant impact on our financial statements. Effect of Newly Issued But Not Yet Effective Accounting Standards 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. Implementation of this ASU is not expected to materially impact the consolidated financial statements or disclosures.
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. 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. 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. 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, 2020 and 2019. 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. LHFI For LHFI 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 both December 31, 2020 and 2019. 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 $62.6 million and $39.8 million, at December 31, 2020 and 2019, respectively, 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 $55.5 million and $27.9 million, respectively, at December 31, 2020 and 2019, 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 Loans with Credit Losses Loans for which it is probable that the Company will not collect all principal and interest due according to contractual terms are measured to determine if any credit loss exists. Allowable methods for determining the amount of credit loss includes estimating the fair value using the fair value of the collateral for collateral-dependent loans. If the loan is identified as collateral-dependent, the fair value method of measuring the amount of credit loss is utilized. This method requires obtaining a current independent appraisal of the collateral and applying a discount factor to the value. Loans that have experienced a credit loss that are collateral-dependent are classified within Level 3 of the fair value hierarchy when the credit loss is determined using the fair value method. The fair value of loans that have experienced a credit loss with specific allocated losses was approximately $12.3 million and $1.9 million at December 31, 2020, and December 31, 2019, respectively.

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. (3) Net income available to common stockholders for basic and diluted earnings per share may differ under the two-class method as a result of adding common stock equivalents for options to dilutive shares outstanding, which alters the ratio used to allocate earnings to common stockholders and participating securities for the purposes of calculating diluted earnings per share. (4) Due to the combined impact of the repurchase of common stock on the quarterly average common shares outstanding calculation compared to the impact of the repurchase of common stock on the year-to-date average common shares outstanding calculation, and the effect of rounding, the sum of the quarterly earnings per common share may not equal the year-to-date earnings per common share amount.

Origination of PPP loans contributed $9.6 million of the increase in net deferred loan fees during the year.
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. In connection with the review of the loan portfolio, the Company considers risk elements attributable to particular loan types or categories in assessing the quality of individual loans. The list of loans to be reviewed for possible individual evaluation consists of nonaccrual commercial loans over $100,000 with direct exposure, unsecured loans over 90 days past due, commercial loans classified substandard or worse over $100,000 with direct exposure, TDRs, consumer loans greater than $100,000 with a FICO score under 625, loans greater than $100,000 in which the borrower has filed bankruptcy, and all loans 180 days or more past due. Loans under $50,000 will be evaluated collectively in designated pools unless a loss exposure has been identified. Some additional risk elements considered by loan type include: • for commercial real estate loans, the debt service coverage ratio, operating results of the owner in the case of owner occupied properties, the loan to value ratio, the age and condition of the collateral and the volatility of income, property value and future operating results typical of properties of that type; • for construction, land and land development loans, the perceived feasibility of the project, including the ability to sell developed lots or improvements constructed for resale or the ability to lease property constructed for lease, the quality and nature of contracts for presale or prelease, if any, experience and ability of the developer and loan to value ratio; • for residential mortgage loans, the borrower's ability to repay the loan, including a consideration of the debt to income ratio and employment and income stability, the loan-to-value ratio, and the age, condition and marketability of the collateral; and • for commercial and industrial loans, the debt service coverage ratio (income from the business in excess of operating expenses compared to loan repayment requirements), the operating results of the commercial, industrial or professional enterprise, the borrower's business, professional and financial ability and expertise, the specific risks and volatility of income and operating results typical for businesses in that category and the value, nature and marketability of collateral. The following table reflects recorded investments in loans by credit quality indicator and origination year at December 31, 2020, excluding loans held for sale and loans accounted for at fair value.

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.
