ACCOUNTING STANDARDS
ACCOUNTING STANDARDS	NOTE 3 – ACCOUNTING STANDARDS Effect of Recently Adopted Accounting Standards Accounting Standards Update (“ASU”) 2016-13, Financial Instruments - Credit Losses (“ ) ASC 326 also applies to off-balance sheet credit (“OBSC”) exposures such as unfunded loan commitments, letters of credit and other financial guarantees that are not unconditionally cancellable by the Company. The Company estimates expected credit losses over the contractual period in which the Company is exposed to credit risk via a contractual obligation to extend credit, unless that obligation is unconditionally cancellable by the Company. The ACL on OBSC exposures is adjusted as a provision for credit loss expense. The estimate includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over its estimated life. Expected credit losses related to OBSC exposures are presented as a liability. The allowance for loan credit losses (“ACL”) represents the estimated losses for financial assets accounted for on an amortized cost basis. Expected losses are calculated using relevant information, from internal and external sources, about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. Historical credit loss experience provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made for differences in current loan-specific risk characteristics such as differences in underwriting standards, portfolio mix, delinquency level, or term as well as for changes in environment conditions, such as changes in unemployment rates, property values, or other relevant factors. Management may selectively apply external market data to subjectively adjust the Company’s own loss history including index or peer data. Expected losses are estimated over the contractual term of the loans, adjusted for expected prepayments when appropriate. The contractual term excludes expected extensions, renewals, and modifications. Loans are charged-off against the allowance when management believes the uncollectibility of a loan balance is confirmed and recoveries are credited to the allowance when received. Expected recoveries amounts may not exceed the aggregate of amounts previously charged-off. The ACL is measured on a collective basis when similar risk characteristics exist. Generally, collectively assessed loans are grouped by call code (segments). Segmenting loans by call code will group loans that contain similar types of collateral, purposes, and are usually structured with similar terms making each loan’s risk profile very similar to the rest in that segment. Each of these segments then flows up into one of the four bands (bands), Commercial, Financial, and Agriculture, Commercial Real Estate, Consumer Real Estate, and Consumer Installment. In accordance with the guidance in ASC 326, the Company redefined its LHFI portfolio segments and related loan classes based on the level at which risk is monitored within the ACL methodology. Construction loans for 1-4 family residential properties with a call code 1A1, and other construction, all land development and other land loans with a call code 1A2 were previously separated between the Commercial Real Estate or Consumer Real Estate bands based on loan type code. Under our ASC 326 methodology 1A1 loans are all defined as part of the Consumer Real Estate band and 1A2 loans are all defined as part of the Commercial Real Estate Band. The probability of default (“PD”) calculation analyzes the historical loan portfolio over the given lookback period to identify, by segment, loans that have defaulted. A default is defined as a loan that has moved to past due 90 days and greater, nonaccrual status, or experienced a charge-off during the period. The model observes loans over a 12-month window, detecting any events previously defined. This information is then used by the model to calculate annual iterative count-based PD rates for each segment. This process is then repeated for all dates within the historical data range. These averaged PD’s are used for reversion back to the historical mean. The historical data used to calculate this input was captured by the Company from 2009 through the most recent quarter end. The Company utilizes reasonable and supportable forecasts of future economic conditions when estimating the ACL on loans. The model’s calculation also includes a 24-month forecasted PD based on a regression model that calculated a comparison of the Company’s historical loan data to various national economic metrics during the same periods. The results showed the Company’s past losses having a high rate of correlation to unemployment, both regionally and nationally. Using this information, along with the most recently published Wall Street Journal survey of sixty economists’ forecasts predicting unemployment rates out over the next eight quarters, a corresponding future PD can be calculated for the forward-looking 24-month period. This data can also be used to predict loan losses at different levels of stress, including a baseline, adverse and severely adverse economic condition. After the forecast period, PD rates revert to the historical mean of the entire data set. The loss given default (“LGD”) calculation is based on actual losses (charge-offs, net recoveries) at a loan level experienced over the entire lookback period aggregated to get a total for each segment of loans. The aggregate loss amount is divided by the exposure at default to determine an LGD rate. Defaults occurring during the lookback period are included in the denominator, whether a loss occurred or not and exposure at default is determined by the loan balance immediately preceding the default event. If there is not a minimum of five past defaults in a loan segment, or less than 15.0% calculated LDG rate, a proxy index is used. This index is proprietary to the Company’s ACL modeling vendor derived from loss data of other client institutions similar in organization structure to the Company. The vendor also provides a “crisis” index derived from loss data between the post-recessionary years of 2008-2013 that the Company uses. The model then uses these inputs in a non-discounted version of discounted cash flow (“DCF”) methodology to calculate the quantitative portion of estimated losses. The model creates loan level amortization schedules that detail out the expected monthly payments for a loan. These expected cash flows are discounted back to present value using the loan’s coupon rate instead of the effective interest rate. On a quarterly basis, the Company uses modeling of internal credit portfolio data, such as changes in portfolio volume and composition, underwriting practices, and levels of past due loans, nonaccruals and classified assets along with other external information not used in the quantitative calculation to determine if any subjective qualitative adjustments are required so that all significant risks are incorporated to form a sufficient basis to estimate credit losses. The Company has purchased loans, some of which have experienced more than insignificant credit deterioration since origination. These purchased credit deteriorated (“PCD”) loans are recorded at the amount paid. It is the Company’s policy that a loan meets this definition if it is adversely risk rated as Non-Pass (Special Mention, Substandard, Doubtful or Loss) including non-accrual loans, as well as loans identified as TDR’s. An allowance for credit losses is determined using the same methodology as other loans held for investment. The initial allowance for credit losses determined on a collective basis is allocated to individual loans. The sum of the loan’s purchase price and allowance for credit losses becomes its initial amortized cost basis. The difference between the initial amortized cost basis and the par value of the loan is a noncredit discount or premium, which is amortized into interest income over the life of the loan. Subsequent changes to the allowance for credit losses are recorded through provision expense. Upon adoption of ASC 326, the Company elected to maintain segments of loans that were previously accounted for under ASC 310-30 Accounting for Purchased Loans with Deteriorated Credit Quality The Company adopted ASC 326 using the prospective transition approach for PCD assets that were previously classified as purchased credit impaired (“PCI”) and accounted for under ASC 310-30. In accordance with the standard, management did not reassess whether PCI assets met the criteria of PCD assets as of the date of adoption. Upon adoption of ASC 326, the Company increased the ACL by $1.1 million and adjusted the amortized cost basis of the PCD assets. The remaining noncredit discount of approximately $685 thousand (based on the adjusted amortized cost basis) will be accreted into interest income at the effective interest rate as of January 1, 2021.Loans that do not share risk characteristics are evaluated on an individual basis. Loans evaluated individually are not included in the collective evaluation. Loans classified as nonaccrual, troubled debt restructuring (“TDRs”), greater than 90 days past due and still accruing interest, and PCD loans that are collateral dependent will be reviewed quarterly for potential individual assessment. Any loan classified as nonaccrual, TDR, or PCD that is not determined to need individual assessment will be evaluated collectively within its respective segment. ASC 326 requires that a loan be evaluated for losses individually and reserved for separately, if the loan does not share similar risk characteristics to any other loan segments. The Company’s process for determining which loans require specific evaluation follows the standard and is two-fold. All non-performing loans, including nonaccrual loans, loans considered to be TDRs or PCDs, are evaluated to determine if they meet the definition of collateral dependent under the new standard. These are loans where no more payments are expected from the borrower, and foreclosure or some other collection action is probable. Secondly, all non-performing loans that are not considered to be collateral dependent, but are 90 days or greater past due and/or have a balance of $500 thousand or greater, will be individually reviewed to determine if the loan displays similar risk characteristic to substandard loans in the related segment. 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. The allowance for OBSC exposures was determined using the same methodology that is applied to LHFI. Utilization rates are determined based on historical usage. The Company adopted ASC 326 using the prospective transition approach for debt securities for which other-than-temporary impairment had been recognized prior to January 1, 2021. As of December 31, 2020, the Company did not have any other-than-temporarily impaired investment securities. Therefore, upon adoption of ASC 326, the Company determined that an allowance for credit losses on available-for-sale securities was not deemed material. Securities available-for-sale are reported at fair value with unrealized holding gains and losses reported as a separate component of stockholders’ equity and other comprehensive income (loss), net of taxes. Securities that are held as available-for-sale are used as a part of our asset/liability management strategy. Securities that may be sold in response to interest rate changes, changes in prepayment risk, the need to increase regulatory capital, and other similar factors are classified as available-for-sale. The Company evaluates all securities quarterly to determine if any securities in a loss position require a provision for credit losses in accordance with ASC 326, Measurement of Credit Losses on Financial Instruments that the Company will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through income. For securities that do not meet these criteria, the Company evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, the Company considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive income. Changes in the allowance for credit losses are recorded as provision for (or reversal of) credit loss expense. Losses are charged against the allowance when management believes the uncollectability of a security is confirmed or when either of the criteria regarding intent or requirement to sell is met. Accrued interest receivable on available-for-sale debt securities totaled $5.3 million at December 31, 2020 and is excluded from the estimate of credit losses. The Company made the following policy elections related to the adoption of the guidance in ASC 326: ● Accrued interest will be written off against interest income when the related financial asset is charged off. 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. The adoption of ASC 326 increased the allowance for credit losses on loans by approximately $397 thousand and OBSC exposures by approximately $718 thousand at January 1, 2021, as shown below. The increase in the allowance for credit losses on loans includes the $1.1 million increase for PCD loans as discussed above, less a decrease in ACL for certain pooled loans: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ($ in thousands) ​ ​ ​ January 1, ​ ​ December 31, ​ ​ ​ ​ 2021 ​ ​ 2020 ​ ​ ​ ​ As Reported ​ ​ Pre-ASC 326 ​ Transition ​ Under Assets: ​ Adoption ​ Adjustment ​ ASC 326 Loans ​ ​ ​ Commercial, financial, and agriculture ​ $ 6,214 ​ $ (1,153) ​ $ 5,061 Commercial real estate ​ 24,319 ​ (4,032) ​ 20,287 Consumer real estate ​ 4,736 ​ 5,629 ​ 10,365 Consumer installment ​ 551 ​ (47) ​ 504 Allowance for credit losses on loans ​ $ 35,820 ​ $ 397 ​ $ 36,217 Liabilities: ​ ​ ​ Allowance for credit losses on OBSC exposures ​ — ​ 718 ​ 718 Total allowance for credit losses ​ $ 35,820 ​ $ 1,115 ​ $ 36,935 ​ The transition had no net impact to retained earnings because the allowance for OBSC exposures was offset by decrease in the allowance for certain pooled loans.

BUSINESS COMBINATIONS
BUSINESS COMBINATIONS	NOTE 4 – BUSINESS COMBINATIONS Acquisitions Southwest Financial Corporation On April 3, 2020, the Company completed its acquisition of Southwest Financial Corporation (“SWG”), and immediately thereafter merged its wholly-owned subsidiary, Southwest Georgia Bank with and into The First. The Company paid a total consideration of $47.9 million to the SWG shareholders as consideration in the merger, which included 2,546,967 shares of Company common stock and approximately $2 thousand in cash. As a result of the acquisition, the Company will have an opportunity to increase its deposit base and reduce transaction costs. The Company also expects to reduce costs through economies of scale. In connection with the acquisition, the Company recorded a $7.8 million bargain purchase gain and $4.6 million core deposit intangible. The bargain purchase gain was generated as a result of the estimated fair value of net assets acquired exceeding the merger consideration, based on provisional fair values, which is reflected as an adjustment to retained earnings. The bargain purchase gain is considered non-taxable for income taxes purposes. The core deposit intangible will be amortized to expense over 10 years. The Company acquired the $394.6 million loan portfolio at an estimated fair value discount of $2.3 million. The discount represents expected credit losses, adjusted for market interest rates and liquidity adjustments. Expenses associated with the SWG acquisition were $210 thousand for the three months period ended March 31, 2020. These costs included system conversion and integrating operations charges and legal and consulting expenses, which have been expensed as incurred. The assets acquired and liabilities assumed and consideration paid in the acquisition of SWG were recorded at their estimated fair values based on management’s best estimates using information available at the date of the acquisition and are subject to adjustment for up to one year after the closing date of the acquisition. While the fair values are not expected to be materially different from the estimates, accounting guidance provides that an acquirer must recognize adjustments to provisional amounts that are identified during the measurement period, which ran through April 3, 2021 in respect of SWG, in the measurement period in which the adjustment amounts are determined. The acquirer must record in the financial statements, the effect on earnings of changes in depreciation, amortization or other income effects, if any, as a result of changes to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. The items most susceptible to adjustment are the credit fair value adjustments on loans, core deposit intangible and the deferred income tax assets resulting from the acquisition.

FAIR VALUE DISCLOSURES AND REPORTING, THE FAIR VALUE OPTION AND FAIR VALUE MEASUREMENTS
FAIR VALUE DISCLOSURES AND REPORTING, THE FAIR VALUE OPTION AND FAIR VALUE MEASUREMENTS	NOTE 8 – FAIR VALUE DISCLOSURES AND REPORTING, THE FAIR VALUE OPTION AND FAIR VALUE MEASUREMENTS Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the assets or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair values: Level 1 Level 2 Level 3 The following methods and assumptions were used by the Company to estimate its financial instrument fair values disclosed at March 31, 2021 and December 31, 2020: ● Investment Securities : The fair value for investment securities are determined by quoted market prices, if available (Level 1). For securities where, quoted prices are not available, fair values are calculated based on market prices of similar securities (Level 2), using matrix pricing. Matrix pricing is a mathematical technique commonly used to price debt securities that are not actively traded, valuing debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2 inputs). For securities where quoted prices or market prices of similar securities are not available, fair values are calculated using discounted cash flows or other market indicators (Level 3). ● Loans Held For Sale : Since loans designated by the Company as available-for-sale are typically sold shortly after making the decision to sell them, realized gains or losses are usually recognized within the same period and fluctuations in fair values are not relevant for reporting purposes. If available-for-sale loans are held on our books for an extended period of time, the fair value of those loans is determined using quoted secondary-market prices. ● Individually Evaluated Loans : Loans for which it is probable that the Company will not collect all principal and interest due according to contractual terms are measured for impairment. If the impaired loan is identified as collateral dependent, then the fair value method of measuring the amount of impairment is utilized. This method requires obtaining a current independent appraisal of the collateral. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by independent appraisers to adjust for differences between the comparable sales and income data available for similar loans and collateral underlying such loans. Such adjustments, if any, result in a Level 3 classification of the inputs for determining fair value. The Company generally adjusts the appraisal down by approximately 10 percent to account for selling costs. Non-real estate collateral may be valued using an appraisal, net book value per the borrower’s financial statements, or aging reports, adjusted or discounted based on management’s expertise and knowledge of the client and client’s business, resulting in a Level 3 fair value classification. Impaired loans are evaluated on a quarterly basis for additional impairment. ● Other Real Estate Owned : Other real estate owned consists of properties obtained through foreclosure. The adjustment at the time of foreclosure is recorded through the allowance for credit losses. Fair value of other real estate owned is based on current independent appraisals of the collateral less costs to sell when acquired, establishing a new cost basis. These assets are subsequently accounted for at lower of cost or fair value less estimated costs to sell. Fair value is commonly based on recent real estate appraisals, which are updated no less frequently than annually. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach with data from comparable properties. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments, if any, result in a Level 3 classification of the inputs for determining fair value. In the determination of fair value subsequent to foreclosure, Management also considers other factors or recent developments, such as changes in market conditions from the time of valuation and anticipated sales values considering plans for disposition, which could result in an adjustment to lower the collateral value estimates indicated in the appraisals. The Company generally adjusts the appraisal down by approximately 10 percent to account for selling costs. Periodic revaluations are classified as Level 3 in the fair value hierarchy since assumptions are used that may not be observable in the market. Due to the subjective nature of establishing the fair value when the asset is acquired, the actual fair value of the other real estate owned or foreclosed asset could differ from the original estimate. If it is determined the fair value declines subsequent to foreclosure, a valuation allowance is recorded through other non-interest income. Operating costs associated with the assets after acquisition are also recorded as non-interest expense. Gains and losses on the disposition of other real estate owned and foreclosed assets are netted and recorded in other non-interest income. Other real estate owned is classified within Level 3 of the fair value hierarchy.

In addition, ASC 326 requires financial assets measured at amortized cost, including held-to-maturity debt securities, to measure an expected credit loss under CECL methodology that requires consideration of a broader range of reasonable and supportable information to inform credit losses estimates. For further discussion on the Company's accounting policies and policy elections related to the accounting standard update refer to Note 3 "Accounting Standards" to the Consolidated Financial Statements for additional information. All securities information presented as of March 31, 2021 is in accordance with ASC 326. All securities information presented prior to March 31, 2021 is in accordance with previous applicable GAAP. See the Company's prior accounting policies in Note 1 "Summary of Significant Accounting Policies" of the 2020 Form 10-K. Available-for-sale ASC 326 makes targeted improvements to the accounting for credit losses on securities available-for-sale. The concept of other-than-temporarily impaired has been replaced with the allowance for credit losses. Unlike securities held to maturity, securities available-for-sale are evaluated on an individual level and pooling of securities is not allowed. Quarterly, the Company evaluates if a security has a fair value less than its amortized cost. Once these securities are identified, in order to determine whether a decline in fair value resulted from a credit loss or other factors, the Company performs further analysis as outlined below: ● Review the extent to which the fair value is less than the amortized cost and determine if the decline is indicative of credit loss or other factors. ● The securities that violate the credit loss trigger above would be subjected to additional analysis. ● If the Company determines that a credit loss exists, the credit portion of the allowance will be measured using the DCF analysis using the effective interest rate. The amount of credit loss the Company records will be limited to the amount by which the amortized cost exceeds the fair value. The allowance for the calculated credit loss will be monitored going forward for further credit deterioration or improvement. At March 31, 2021, the results of the analysis did not identify any securities where the decline was indicative of credit loss factors; therefore, no DCF analysis was performed and no credit loss was recognized on any of the securities AFS. Accrued interest receivable is excluded from the estimate of credit losses for securities AFS. At March 31, 2021, accrued interest receivable totaled $5.3 million for securities available-for-sale and was reported in interest receivable on the accompanying Consolidated Balance Sheet. All AFS securities were current with no securities past due or on nonaccrual as of March 31, 2021. The following table summarizes the amortized cost, gross unrealized gains and losses, and estimated fair values of AFS securities at March 31, 2021 and December 31, 2020: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31,2021 ​ ​ ​ ​ ​ Gross ​ Gross ​ Estimated ​ ​ Amortized ​ Unrealized ​ Unrealized ​ Fair ($ in thousands) Cost Gains Losses Value Available-for-sale securities: ​ ​ ​ ​ U.S. Treasury ​ $ 6,056 ​ $ 176 ​ $ 27 ​ $ 6,205 Obligations of U.S. government agencies and sponsored entities ​ ​ 124,614 ​ 1,908 ​ ​ 121 ​ ​ 126,401 Tax-exempt and taxable obligations of states and municipal subdivisions ​ 508,285 ​ 12,319 ​ 4,072 ​ 516,532 Mortgage-backed securities - residential ​ 281,453 ​ 7,365 ​ 1,180 ​ 287,638 Mortgage-backed securities - commercial ​ ​ 163,067 ​ ​ 4,882 ​ ​ 658 ​ ​ 167,291 Corporate obligations ​ 30,026 ​ 1,102 ​ 6 ​ 31,122 Total ​ $ 1,113,501 ​ $ 27,752 ​ $ 6,064 ​ $ 1,135,189 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2020 ​ ​ ​ Gross Gross Estimated ​ Amortized Unrealized Unrealized Fair ($ in thousands) ​ Cost Gains Losses Value Available-for-sale securities: ​ ​ ​ ​ U.S. Treasury ​ $ 9,063 ​ $ 320 ​ $ — ​ $ 9,383 Obligations of U.S. government agencies sponsored entities ​ ​ 97,107 ​ ​ 3,130 ​ ​ 67 ​ ​ 100,170 Tax-exempt and taxable obligations of states and municipal subdivisions ​ 464,348 ​ 16,326 ​ 300 ​ 480,374 Mortgage-backed securities - residential ​ 228,257 ​ 8,206 ​ 42 ​ 236,421 Mortgage-backed securities - commercial ​ 158,784 ​ 6,087 ​ 60 ​ 164,811 Corporate obligations ​ 30,063 ​ 976 ​ 16 ​ 31,023 Total ​ $ 987,622 ​ $ 35,045 ​ $ 485 ​ $ 1,022,182 ​ The amortized cost and fair value of debt securities at March 31, 2021 are shown by contractual maturity.

Available-for-sale securities in unrealized loss positions are evaluated for impairment related to credit losses at least quarterly. The unrealized losses shown above are due to increases in market rates over the yields available at the time of purchase of the underlying securities and not credit quality. The Company does not intend to sell these securities and it is more likely than not that the Company will not be required to sell the investments before recovery of their amortized cost basis. No allowance for credit losses for available-for-sale debt securities was needed at March 31, 2021.

LOANS	NOTE 10 – LOANS On January 1, 2021, the Company adopted ASU 326. The FASB issued ASU 326 to replace the incurred loss model for loans and other financial assets with an expected loss model and requires consideration of a wider range of reasonable and supportable information to determine credit losses. In accordance with ASC 326, the Company has developed an ACL methodology, which replaces its previous allowance for loan losses methodology. All loan information presented as of March 31, 2021 is in accordance with ASC 326. All loan information presented prior to January 1, 2021 is in accordance with previous applicable GAAP. See the Company’s prior accounting policies in Note 1 “Summary of Significant Accounting Policies” of the 2020 Form 10-K. The Company uses four different categories to classify loans in its portfolio based on the underlying collateral securing each loan. The loans grouped together in each category have been determined to share similar risk characteristics with respect to credit quality. Those four categories are commercial, financial and agriculture, commercial real estate, consumer real estate, consumer installment; Commercial, financial and agriculture Commercial real estate Consumer real estate Consumer installment The composition of the loan portfolio as of March 31, 2021 and December 31, 2020, is summarized below: ​ ​ ​ ​ ​ ​ ​ ​ ($ in thousands) March 31, 2021 December 31, 2020 Loans held for sale ​ ​ Mortgage loans held for sale $ 15,119 $ 21,432 Total LHFS ​ $ 15,119 ​ $ 21,432 ​ ​ ​ ​ ​ ​ ​ Loans held for investment ​ ​ Commercial, financial and agriculture (1) ​ $ 550,500 ​ $ 579,443 Commercial real estate ​ 1,633,667 ​ 1,652,993 Consumer real estate ​ 832,327 ​ 850,206 Consumer installment ​ 38,599 ​ 41,036 Total loans ​ 3,055,093 ​ 3,123,678 Less allowance for credit losses ​ (32,663) ​ (35,820) Net LHFI ​ $ 3,022,430 ​ $ 3,087,858 (1) Loan balance includes $221.7 million and $239.7 million in PPP loans as of March 31, 2021 and December 31, 2020, respectively. Accrued interest receivable is not included in the amortized cost basis of the Company's LHFI. At March 31, 2021, accrued interest receivable for LHFI totaled $19.3 million with no related ACL and was reported in interest receivable on the accompanying consolidated balance sheet. Nonaccrual and Past Due LHFI Past due LHFI are loans contractually past due 30 days or more as to principal or interest payments. Generally, the Company will place a delinquent loan in nonaccrual status when the loan becomes 90 days or more past due. At the time a loan is placed in nonaccrual status, all interest which has been accrued on the loan but remains unpaid is reversed and deducted from earnings as a reduction of reported interest income. No additional interest is accrued on the loan balance until the collection of both principal and interest becomes reasonably certain. The following tables presents the aging of the amortized cost basis in past due loans in addition to those loans classified as nonaccrual including PCD loans: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, 2021 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total ​ ​ ​ ​ ​ ​ ​ Past Due Past Due ​ ​ ​ ​ Past Due, ​ ​ ​ ​ ​ 30 to 89 ​ 90 Days or More and ​ ​ ​ ​ ​ ​ ​ Nonaccrual ​ Total ​ Nonaccrual and ($ in thousands) ​ Days ​ Still Accruing ​ Nonaccrual ​ PCD ​ and PCD ​ LHFI ​ PCD with No ACL Commercial, financial and agriculture (1) ​ $ 607 ​ $ — ​ $ 686 ​ $ 320 ​ $ 1,613 ​ $ 550,500 ​ $ 387 Commercial real estate ​ 4,149 ​ 32 ​ 17,489 ​ 3,173 ​ 24,843 ​ 1,633,667 ​ 5,030 Consumer real estate ​ 4,524 ​ 1,047 ​ 2,790 ​ 5,490 ​ 13,851 ​ 832,327 ​ 3,139 Consumer installment ​ 309 ​ — ​ 30 ​ 3 ​ 342 ​ 38,599 ​ — Total ​ $ 9,589 ​ $ 1,079 ​ $ 20,995 ​ $ 8,986 ​ $ 40,649 ​ $ 3,055,093 ​ $ 8,556 (1) Total loan balance includes $221.7 million in PPP loans as of March 31, 2021. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31,2020 ​ ​ ​ Past Due 90 ​ ​ ​ ​ Total ​ ​ ​ Past Due Days or ​ ​ ​ ​ ​ ​ Past Due, ​ ​ ​ 30 to 89 More and Still ​ ​ ​ ​ ​ ​ Nonaccrual ​ Total ($ in thousands) ​ Days ​ Accruing ​ Nonaccrual ​ PCI and PCI ​ LHFI Commercial, financial and agriculture (1) ​ $ 1,007 ​ $ 244 ​ $ 2,197 ​ $ 221 ​ $ 3,669 ​ $ 579,443 Commercial real estate ​ ​ 2,116 ​ ​ 1,553 ​ ​ 19,499 ​ ​ 3,388 ​ ​ 26,556 ​ ​ 1,652,993 Consumer real estate ​ ​ 5,389 ​ ​ 895 ​ ​ 2,480 ​ ​ 5,954 ​ ​ 14,718 ​ ​ 850,206 Consumer installment ​ ​ 419 ​ ​ — ​ ​ 32 ​ ​ 3 ​ ​ 454 ​ ​ 41,036 Total ​ $ 8,931 ​ $ 2,692 ​ $ 24,208 ​ $ 9,566 ​ $ 45,397 ​ $ 3,123,678 (1) Total loan balance as of December 31, 2020 includes $239.7 million in PPP loans. Acquired Loans On January 1, 2021, the Company adopted ASC 326 and elected to account for its existing acquired PCI loans as PCD loans included within the LHFI portfolio. The Company elected to maintain segments of loans that were previously accounted for under ASC 310-30 and will continue to account for these segments as a unit of account unless the loan is collateral dependent. PCD loans that are collateral dependent will be assessed individually. Loans are only removed from the existing segments if they are written off, paid off, or sold. Upon adoption of ASC 326, the ACL was determined for each segment and added to the band's carrying amount to establish a new amortized cost basis. The difference between the unpaid principal balance of the segment and the new amortized cost basis is the noncredit discount of approximately $685 thousand, which will be accreted into interest income over the remaining life of the segment. Changes to the ACL after adoption are recorded through provision expense. As of March 31, 2021, the amortized cost of the Company's PCD loans totaled $13.6 million, which had an estimated ACL of $1.2 million. Prior to the adoption of FASB ASC 326, the Company acquired loans with deteriorated credit quality in 2014, 2017, 2018, 2019 and 2020. These loans were recorded at estimated fair value at the acquisition date with no carryover of the related allowance for loan losses. The acquired loans were segregated as of the acquisition date between those considered to be performing (acquired non-impaired loans) and those with evidence of credit deterioration (PCI loans). Acquired loans are considered to be impaired if it is probable, based on current available information, that the Company will be unable to collect all cash flows as expected. If expected cash flows cannot reasonably be estimated as to what will be collected, there will not be any interest income recognized on these loans. Total outstanding PCI loans were $13.1 million and the related purchase accounting discount was $3.6 million as of March 31, 2020. The outstanding balance of these loans is the undiscounted sum of all amounts, including amounts deemed principal, interest, fees, penalties, and other under the loans, owed at the reporting date, whether or not currently due and whether or not any such amounts have been charged off. ​ Changes in the carrying amount and accretable yield for purchased credit impaired loans were as follows at March 31, 2020 ($ in thousands): ​ ​ ​ ​ ​ ​ ​ Accretable ​ Yield Balance at beginning of period, January 1 ​ $ 3,417 Additions, including transfers from non-accretable ​ 337 Accretion ​ (148) Balance at end of period, March 30, 2020 ​ $ 3,606 ​ Impaired LHFI Prior to the adoption of FASB ASC 326, the Company individually evaluated impaired LHFI. The following table provides a detail of impaired loans broken out according to class as of December 31, 2020. The following table does not include PCI loans. The recorded investment included in the following table represents customer balances net of any partial charge-offs recognized on the loans, net of any deferred fees and costs. Recorded investment excludes any insignificant amount of accrued interest receivable on loans 90-days or more past due and still accruing.

The gross interest income that would have been recorded in the period that ended if the nonaccrual loans had been current in accordance with their original terms and had been outstanding throughout the period or since origination, if held for part of the three months ended March 31, 2020, was $377 thousand. The Company had no loan commitments to borrowers in nonaccrual status at March 31, 2020 or December 31, 2020. Troubled Debt Restructurings If the Company grants a concession to a borrower for economic or legal reasons related to a borrower’s financial difficulties that it would not otherwise consider, the loan is classified as TDRs. In response to the Coronavirus Disease 2019 (“COVID-19”) pandemic and its economic impact to its customers, the Company implemented a short-term modification program in accordance with interagency regulatory guidance to provide temporary payment relief to those borrowers directly impacted by COVID-19 who were not more than 30 days past due at the time of the modification. This program allowed for a deferral of payments for up two successive 90-day periods for a cumulative maximum of 180 days. Pursuant to interagency guidance, such short-term deferrals are not deemed to meet the criteria for reporting as TDRs. For borrowers requiring a longer-term modification following the short-term loan modification program the Company worked with these borrowers whose loans were not more 30 days past due at December 31, 2019 and who required modification as a result of COVID-19 to modify such loans under Section 4013 of the Coronavirus Aid, Relief, and Economic Security (“CARES Act”). As of March 31, 2021, and December 31, 2020, the Company had TDRs totaling $23.1 million and $27.5 million. As of March 31, 2021, the Company had no additional amount committed on any loan classified as TDR. As of March 31, 2021, TDRs had a related ACL of $2.7 million, compared to a related allowance for loan loss of $2.4 million at March 31, 2020, and resulting in no charge-offs for the three months ended March 31, 2021 and 2020. The were no TDRs added during the three months ended March 31, 2021.

The following provides a qualitative description by class of loan of the collateral that secures the Company’s collateral-dependent LHFI: ● Commercial, financial and agriculture – Loans within these loan classes are secured by equipment, inventory accounts, and other non-real estate collateral. There have been no significant changes to the collateral that secures these financial assets during the period. ● Commercial real estate – Loans within these loan classes are secured by commercial real property. There have been no significant changes to the collateral that secures these financial assets during the period. ● Consumer real estate - Loans within these loan classes are secured by consumer real property. There have been no significant changes to the collateral that secures these financial assets during the period. ● Consumer installment - Loans within these loan classes are secured by consumer goods, equipment, and non-real estate collateral. There have been no significant changes to the collateral that secures these financial assets during the period. Loan Participations The Company has loan participations, which qualify as participating interest, with other financial institutions. As of March 31, 2021, these loans totaled $124.7 million, of which $80.4 million had been sold to other financial institutions and $44.3 million was retained by the Company. The loan participations convey proportionate ownership rights with equal priority to each participating interest holder; involving no recourse (other than ordinary representations and warranties) to, or subordination by, any participating interest holder; all cash flows are divided among the participating interest holders in proportion to each holder’s share of ownership; and no holder has the right to pledge the entire financial assets unless all participating interest holders agree. Credit Quality Indicators The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt, such as current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Company analyzes loans individually to classify the loans as to credit risk. The Company uses the following definitions for risk ratings: Pass: Special Mention Substandard Doubtful The tables below present the amortized cost basis of loans by credit quality indicator and class of loans based on the most recent analysis performed.

COVID-19 UPDATE
COVID-19 UPDATE	NOTE 11 – COVID-19 UPDATE The COVID-19 pandemic continues to have significant effects on global markets, supply chains, businesses and communities. COVID-19 could potentially impact the Company’s future financial condition and results of operations including but not limited to additional credit loss reserves, additional collateral and/or modifications to debt obligations, liquidity, limited dividend payouts or potential shortages of personnel. Management continues to take appropriate actions to mitigate the negative impact the virus has on the Company, including restricting employee travel, directing employees to work remotely, cancelling in-person meetings and implementing our business continuity plans and protocols to the extent necessary. The pandemic is having an adverse impact on certain industries the Company serves, including hotels, restaurants, retail, and direct energy. As of March 31,2021, the Company’s aggregate outstanding exposure in these segments was $436.5 million, and total loan modifications resulting from COVID-19 were approximately $45.7 million. While it is still not yet possible to know the full effect that the pandemic will have on the economy, or to what extent this crisis will impact the Company, all available current industry statistics and internal monitoring of loan repayment ability and payment forgiveness across the portfolio has been analyzed in an attempt to understand the correlation with asset quality and degree of possible deterioration. Despite recent improvements in certain economic indicators, significant constraints to commerce remain in place, and significant uncertainty remains over the timing and scope of additional government stimulus packages, and the economic impact resulting from the outcome of the November 2020 elections. The duration and extent of the downturn and speed of the related recovery on our business, customers, and the economy as a whole remains uncertain. It is unknown how long the adverse conditions associated with the COVID-19 pandemic will last and what the complete financial effect will be to the Company. It is reasonably possible that estimates made in the financial statements could be materially and adversely impacted in the near term as a result of these conditions, including the determination of the allowance for credit losses, fair value of financial instruments, impairment of goodwill and other intangible assets and income taxes.
