Summary of Significant Accounting Policies
Summary of Significant Accounting Policies	(1) Summary of Significant Accounting Policies Hawthorn Bancshares, Inc. (the Company) through its subsidiary, Hawthorn Bank (the Bank), provides a broad range of banking services to individual and corporate customers located within the Missouri communities in and surrounding Jefferson City, Columbia, Clinton, Warsaw, Springfield, St. Louis, and the greater Kansas City metropolitan area. The Company is subject to competition from other financial and nonfinancial institutions providing financial products. Additionally, the Company and its subsidiaries are subject to the regulations of certain regulatory agencies and undergo periodic examinations by those regulatory agencies. The accompanying unaudited consolidated financial statements of the Company have been prepared in conformity with U.S. generally accepted accounting principles (U.S. GAAP) for interim financial information and with the instructions to Form 10-Q, and Rule 10-01 of Regulation S-X. Accordingly, the unaudited consolidated financial statements do not include all of the information and disclosures required by U.S. GAAP for complete financial statements and should be read in conjunction with the consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020. The preparation of the consolidated financial statements includes all adjustments that, in the opinion of management, are necessary in order to make those statements not misleading. Management is required to make estimates and assumptions, including the determination of the allowance for loan losses, real estate acquired in connection with foreclosure or in satisfaction of loans, and fair values of investment securities available-for-sale that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates and assumptions are subject to many risks and uncertainties, including changes in interest rates and other general economic, business and political conditions, including the effects of the novel coronavirus (COVID-19) pandemic or any resurgence thereof, including its potential effects on the economic environment, our customers and our operations, as well as any changes to federal, state and local government laws, regulations and orders in connection with the pandemic. Actual results could differ from those estimates. The Company’s management has evaluated and did not identify any subsequent events or transactions requiring recognition or disclosure in the consolidated financial statements. Stock Dividend Operating, Accounting and Reporting Considerations related to COVID-19 The COVID-19 pandemic has negatively impacted the global economy, including the United States. In response to this crisis, the Coronavirus Aid, Relief, and Economic Security (CARES) Act was passed by Congress and signed into law on March 27, 2020. The CARES Act, along with subsequent relief programs, provided substantial funding to fight the COVID-19 pandemic and stimulate the economy by supporting individuals and businesses through loans, grants, tax changes, and other types of relief.

Loan charge-offs reduce the allowance for loan losses, and recoveries of loans previously charged off are added back to the allowance. If management determines that it is probable that all amounts due on a loan will not be collected under the original terms of the loan agreement, the loan is considered to be impaired. These loans are evaluated individually for impairment, and in conjunction with current economic conditions and loss experience, specific reserves are estimated as further discussed below. Loans not individually evaluated are aggregated by risk characteristics and reserves are recorded using a consistent methodology that considers historical loan loss experience by loan type, delinquencies, current economic conditions, loan risk ratings and industry concentration. These historical loss rates for each risk group are used as the starting point to determine loss rates for measurement purposes. The historical loan loss rates are multiplied by loss emergence periods (LEP) which represent the estimated time period between a borrower first experiencing financial difficulty and the recognition of a loss. Management's look-back period began with loss history in the first quarter 2012 as the starting point through the current quarter and it will continue to include this starting point going forward. The look-back period will continue to be evaluated and will be adjusted once a sustained loss producing downturn is recognized and found to be representative of historical losses expected for the current portfolio. The Company’s methodology includes qualitative risk factors that allow management to adjust its estimates of losses based on the most recent information available and to address other limitations in the quantitative component that is based on historical loss rates. Such risk factors are generally reviewed and updated quarterly, as appropriate, and are adjusted to reflect changes in national and local economic conditions and developments, the nature, volume and terms of loans in the portfolio, including changes in volume and severity of past due loans, the volume of non-accrual loans, and the volume and severity of adversely classified or graded loans, loan concentrations, assessment of trends in collateral values, assessment of changes in the quality of the Company’s internal loan review department, and changes in lending policies and procedures, including underwriting standards and collections, charge-off and recovery practices. When the COVID-19 pandemic surfaced in the first quarter of 2020, management reassessed the calculation of the allowance for loan loss by increasing the economic qualitative factor in order to capture the impact on the credit risk present in the loan portfolio given the economic environment that existed at that time. As of the fourth quarter of 2020, management reassessed the qualitative factor and economic indicators. Enough time had passed so that data after the outbreak would be available and a better interpretation of the impact of the virus on the economy. Management determined that the local market and economy had been able to transition to a functional level while adapting to the new requirements aimed at stopping the spread of the virus and returned to calculating the qualitative adjustment according to the Company's methodology detailed above. Additionally, the funding of $88.4 million and $47.5 million in SBA PPP loans during 2020 and 2021, respectively, required management to assess the methodology that would be adopted in regard to the allowance for loan losses applicable to these loans. As the SBA PPP loans are expected to be mostly paid off in the next six All SBA PPP loans have a 1% interest rate and the Company earns a fee that is based upon a tiered schedule corresponding with the amount of the loan to the borrower, which is deferred and recognized over the life of the loan. The PPP loan may be forgiven by SBA if the borrower meets certain criteria as defined by the CARES Act. The Company reports these loans at their principal amount outstanding, net of unearned income, unamortized deferred loan fee income and loan origination costs. Interest is accrued as earned and loan origination fees and direct costs are deferred and accreted or amortized into interest income, as an adjustment to the yield, over the life of the loan using the level yield method. When a PPP loan is paid off or forgiven by the SBA, the remaining unaccreted or unamortized net origination fees or costs are immediately recognized into income.

All other loans are collectively evaluated for impairment under ASC 450-20. Impaired loans individually evaluated for impairment totaled $36.1 million and $37.3 million at June 30, 2021 and December 31, 2020, respectively, and are comprised of loans on non-accrual status and loans which have been classified as troubled debt restructuring (TDRs). The net carrying value of impaired loans is based on the fair values of collateral obtained through independent appraisals or internal evaluations, or by discounting the total expected future cash flows. At June 30, 2021, $31.8 million of impaired loans were evaluated based on the fair value less estimated selling costs of the loans' collateral compared to $32.2 million at December 31, 2020. Once the impairment amount is calculated, a specific reserve allocation is recorded. At June 30, 2021, $5.4 million of the Company’s allowance for loan losses was allocated to impaired loans totaling $36.1 million compared to $5.1 million of the Company’s allowance for loan losses allocated to impaired loans totaling approximately $37.3 million at December 31, 2020. Management determined that $12.4 million, or 34%, of total impaired loans required no reserve allocation at June 30, 2021 compared to $11.9 million, or 32%, at December 31, 2020, primarily due to adequate collateral values , The categories of impaired loans at June 30, 2021 and December 31, 2020 are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, ​ December 31, (in thousands) 2021 2020 Non-accrual loans ​ $ 33,783 ​ $ 34,559 Performing TDRs ​ 2,308 ​ 2,776 Total impaired loans ​ $ 36,091 ​ $ 37,335 ​ The following tables provide additional information about impaired loans at June 30, 2021 and December 31, 2020, respectively, segregated between loans for which an allowance has been provided and loans for which no allowance has been provided. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Unpaid ​ ​ ​ ​ Recorded ​ Principal ​ Specific (in thousands) ​ Investment ​ Balance ​ Reserves June 30, 2021 ​ ​ ​ ​ ​ ​ ​ ​ ​ With no related allowance recorded: ​ ​ ​ Commercial, financial and agricultural ​ $ 1,821 ​ $ 1,872 ​ $ — Real estate mortgage − ​ 1,153 ​ 1,261 ​ — Real estate mortgage − ​ ​ 9,465 ​ ​ 9,483 ​ ​ — Total ​ $ 12,439 ​ $ 12,616 ​ $ — With an allowance recorded: ​ ​ ​ Commercial, financial and agricultural ​ $ 5,541 ​ $ 5,618 ​ $ 2,325 Real estate construction − ​ 112 ​ 142 ​ 16 Real estate mortgage − ​ 1,756 ​ 2,191 ​ 242 Real estate mortgage − ​ 16,182 ​ 16,252 ​ 2,764 Installment and other consumer ​ 61 ​ 63 ​ 8 Total ​ $ 23,652 ​ $ 24,266 ​ $ 5,355 Total impaired loans ​ $ 36,091 ​ $ 36,882 ​ $ 5,355 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Unpaid ​ ​ ​ ​ Recorded ​ Principal ​ Specific (in thousands) ​ Investment ​ Balance ​ Reserves December 31, 2020 ​ ​ ​ With no related allowance recorded: ​ ​ ​ Commercial, financial and agricultural ​ $ 1,703 ​ $ 1,731 ​ $ — Real estate mortgage − ​ 1,300 ​ 1,395 ​ — Real estate mortgage − ​ ​ 8,943 ​ ​ 8,943 ​ ​ — Total ​ $ 11,946 ​ $ 12,069 ​ $ — With an allowance recorded: ​ ​ ​ Commercial, financial and agricultural ​ $ 5,849 ​ $ 6,180 ​ $ 2,187 Real estate construction − ​ ​ 192 ​ ​ 192 ​ ​ 27 Real estate construction − ​ 200 ​ 251 ​ 28 Real estate mortgage − ​ 2,326 ​ 2,786 ​ 263 Real estate mortgage − ​ 16,714 ​ 16,787 ​ 2,594 Installment and other consumer ​ 108 ​ 112 ​ 14 Total ​ $ 25,389 ​ $ 26,308 ​ $ 5,113 Total impaired loans ​ $ 37,335 ​ $ 38,377 ​ $ 5,113 ​ The following table presents by class, information related to the average recorded investment and interest income recognized on impaired loans during the periods indicated. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended June 30, ​ Six Months Ended June 30, ​ ​ ​ 2021 ​ 2020 ​ 2021 ​ 2020 ​ ​ ​ ​ ​ ​ Interest ​ ​ ​ ​ Interest ​ ​ ​ ​ Interest ​ ​ ​ ​ Interest ​ ​ ​ Average ​ Recognized ​ Average ​ Recognized ​ Average ​ Recognized ​ Average ​ Recognized ​ ​ ​ Recorded ​ For the ​ Recorded ​ For the ​ Recorded ​ For the ​ Recorded ​ For the ​ (in thousands) Investment Period Ended Investment Period Ended Investment Period Ended Investment Period Ended ​ With no related allowance recorded: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial, financial and agricultural ​ $ 1,826 ​ $ 5 ​ $ 3,059 ​ $ — ​ $ 1,834 ​ $ 13 ​ $ 1,370 ​ $ — ​ Real estate construction − ​ ​ — ​ ​ — ​ ​ 528 ​ ​ — ​ ​ — ​ ​ — ​ ​ 271 ​ ​ — ​ Real estate mortgage − ​ 1,266 ​ 12 ​ 2,758 ​ — ​ 1,391 ​ 21 ​ 1,355 ​ — ​ Real estate mortgage − ​ 9,459 ​ — ​ 1,448 ​ 7 ​ 9,458 ​ — ​ 1,178 ​ 13 ​ Installment and other consumer ​ ​ — ​ ​ — ​ ​ 15 ​ ​ — ​ ​ — ​ ​ — ​ ​ 12 ​ ​ — ​ Total ​ $ 12,551 ​ $ 17 ​ $ 7,808 ​ $ 7 ​ $ 12,683 ​ $ 34 ​ $ 4,186 ​ $ 13 ​ With an allowance recorded: ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial, financial and agricultural ​ $ 5,553 ​ $ 7 ​ $ 1,615 ​ $ 11 ​ $ 5,548 ​ $ 13 ​ $ 1,195 ​ $ 19 ​ Real estate construction − ​ ​ 125 ​ ​ — ​ ​ — ​ ​ — ​ ​ 158 ​ ​ — ​ ​ — ​ ​ — ​ Real estate construction − ​ 165 ​ — ​ 766 ​ — ​ 182 ​ — ​ 142 ​ — ​ Real estate mortgage − ​ 1,692 ​ 4 ​ 3,724 ​ 8 ​ 1,779 ​ 11 ​ 2,990 ​ 28 ​ Real estate mortgage − ​ 16,323 ​ 8 ​ 540 ​ 3 ​ 16,189 ​ 15 ​ 438 ​ 6 ​ Installment and other consumer ​ 58 ​ — ​ 147 ​ 1 ​ 71 ​ 3 ​ 135 ​ 7 ​ Total ​ $ 23,916 ​ $ 19 ​ $ 6,792 ​ $ 23 ​ $ 23,927 ​ $ 42 ​ $ 4,900 ​ $ 60 ​ Total impaired loans ​ $ 36,467 ​ $ 36 ​ $ 14,600 ​ $ 30 ​ $ 36,610 ​ $ 76 ​ $ 9,086 ​ $ 73 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ The recorded investment varies from the unpaid principal balance primarily due to partial charge-offs taken resulting from current appraisals received. The amount recognized as interest income on impaired loans continuing to accrue interest, primarily related to TDRs, was $36,000 and $76,000 for the three and six months ended June 30, 2021, respectively, compared to $30,000 and $73,000 for the three and six months ended June 30, 2020, respectively. The average recorded investment in impaired loans is calculated on a monthly basis during the periods reported. Delinquent and Non-Accrual Loans The delinquency status of loans is determined based on the contractual terms of the notes. Borrowers are generally classified as delinquent once payments become 30 days or more past due. The Company’s policy is to discontinue the accrual of interest income on any loan when, in the opinion of management, the ultimate collectability of interest or principal is no longer probable. In general, loans are placed on non-accrual when they become 90 days or more past due. However, management considers many factors before placing a loan on non-accrual, including the delinquency status of the loan, the overall financial condition of the borrower, the progress of management’s collection efforts and the value of the underlying collateral. Subsequent interest payments received on non-accrual loans are applied to principal if any doubt exists as to the collectability of such principal; otherwise, such receipts are recorded as interest income on a cash basis. Non-accrual loans are returned to accrual status when, in the opinion of management, the financial condition of the borrower indicates that the timely collectability of interest and principal is probable and the borrower demonstrates the ability to pay under the terms of the note through a sustained period of repayment performance, which is generally six months.

Their delinquency status will not change through the forbearance period as they are fulfilling the agreement they have made with the Company. Of the total remaining $42.8 million loan modifications under the CARES Act, $23.5 million, are on non-accrual status at June 30, 2021. ​ Credit Quality The Company categorizes loans into risk categories based upon an internal rating system reflecting management’s risk assessment. Loans are placed on watch substandard non-accrual loans for presentation purposes. It is the Company’s policy to discontinue the accrual of interest income on loans when management believes that the collection of interest or principal is doubtful.

At December 31, 2020, loans classified as TDRs totaled $3.7 million, of which $0.9 million were classified as non-performing TDRs and $2.8 million were classified as performing TDRs. Both performing and non-performing TDRs are considered impaired loans. When an individual loan is determined to be a TDR, the amount of impairment is based upon the present value of expected future cash flows discounted at the loan’s effective interest rate or the fair value of the underlying collateral less applicable selling costs. Accordingly, specific reserves of $154,000 and $214,000 related to TDRs were allocated to the allowance for loan losses at June 30, 2021 and December 31, 2020, respectively. Beginning in 2020, the Company began offering short-term loan modification to assist borrowers during the COVID-19 pandemic. These modifications generally meet the criteria of both Section 4013 of the CARES Act and the join interagency statement, and therefore, the Company does not account for such loan modifications as TDRs.

The portfolio included 78 securities having an aggregate fair value of $86.7 million that were in a loss position at June 30, 2021. Securities identified as temporarily impaired which had been in a loss position for 12 months or longer totaled $1.2 million at fair value at June 30, 2021. The $1.2 million aggregate unrealized loss included in accumulated other comprehensive loss at June 30, 2021 was caused by interest rate fluctuations. The total available-for-sale portfolio consisted of approximately 308 securities at December 31, 2020. The portfolio included 10 securities having an aggregate fair value of $12.7 million that were in a loss position at December 31, 2020. Securities identified as temporarily impaired which had been in a loss position for 12 months or longer totaled $1.2 million at fair value at December 31, 2020. The $325,000 aggregate unrealized loss included in accumulated other comprehensive loss at December 31, 2020 was caused by interest rate fluctuations. Because the decline in fair value is attributable to changes in interest rates and not credit quality, these investments were not considered other-than-temporarily impaired at June 30, 2021 and December 31, 2020, respectively. In the absence of changes in credit quality of these investments, the fair value is expected to recover on all debt securities as they approach their maturity date or re-pricing date, or if market yields for such investments decline. In addition, the Company does not have the intent to sell these investments over the period of recovery, and it is not more likely than not that the Company will be required to sell such investment securities.

Leases
Leases	​ ​ ​ (7) Leases The Company's leases primarily consist of office space and bank branches with remaining lease terms of generally 1 respectively. As of June 30, 2021, the weighted-average remaining lease term on these operating leases is approximately 6.9 years and the weighted-average discount rate used to measure the lease liabilities is approximately 4.0%. Operating leases in which the Company is the lessee are recorded as operating lease ROU assets and operating lease liabilities. Currently, the Company does not have any finance leases. The ROU assets are included in premises and equipment, net on the consolidated balance sheets. Operating lease ROU assets represent the Company's right to use an underlying asset during the lease term and operating lease liabilities represent the Company's obligation to make lease payments arising from the lease. ROU assets and operating lease liabilities are recognized at lease commencement based on the present value of the remaining lease payments using a discount rate that represents the Company's incremental borrowing rate at the lease commencement date. Operating lease cost, which is comprised of amortization of the ROU asset and the implicit interest accreted on the operating lease liability, is recognized on a straight-line basis over the lease term, and is recorded in net occupancy expense in the consolidated statements of income. The operating lease cost was $95,000 and $196,000 for the three and six months ended June 30, 2021, respectively, compared to $80,000 and $166,000 for the three and six months ended June 30, 2020, respectively. At adoption of Accounting Standards Update (ASU) 2016-02 on January 1, 2019, lease and non-lease components of new lease agreements are accounted for separately. Lease components include fixed payments including rent, real estate taxes and insurance costs and non-lease components include common-area maintenance costs. Leases with an initial term of 12 months or less are not recorded on the balance sheet; the Company recognizes lease expense for these leases on a straight-line basis over the lease term. Operating lease expense for these leases was $19,000 and $32,000 for the three and six months ended June 30, 2021, respectively, compared to $25,000 and $60,000 for the three and six months ended June 30, 2020, respectively.

Income Taxes
Income taxes	(8) Income Taxes Income taxes as a percentage of earnings before income taxes as reported in the consolidated financial statements were 19.7% and 19.2% for the three and six months ended June 30, 2021, respectively, compared to 18.6% and 17.9% for the three and six months ended June 30, 2020, respectively. The increase in the effective tax rate for each of the three and six months ended June 30, 2021 compared to the three and six months ended June 30, 2020 was primarily attributable to the increase in earnings and an increase in state taxes attributed to elevated earnings. The effective tax rate for each of the three and six months ended June 30, 2021 and 2020, respectively, is lower than the U.S. federal statutory rate of 21% primarily due to tax-free revenues. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income of the appropriate character during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning initiatives in making this assessment. In management's opinion, the Company will more likely than not realize the benefits of its deferred tax assets and, therefore, has not established a valuation allowance against its deferred tax assets as of June 30, 2021. Management arrived at this conclusion based upon the level of historical taxable income and projections for future taxable income of the appropriate character over the periods in which the deferred tax assets are deductible. The Company follows ASC Topic 740, Income Taxes, .

Beginning January 1, 2018 and for all retrospective periods presented, the Company adopted the guidance under ASU 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost Effective July 1, 2017, the Company amended the pension plan to effectuate a “soft freeze” such that no individual hired (or rehired in the case of a former employee) by the Company after September 30, 2017, whether or not such individual is or was a vested member in the plan, will be eligible to be an active member and be entitled to accrue any benefits under the plan. Components of Net Pension Cost and Other Amounts Recognized in Accumulated Other Comprehensive Income The following items are components of net pension cost for the periods indicated: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Six Months Ended June 30, ​ (in thousands) 2021 2020 ​ Service cost - benefits earned during the year ​ $ 1,692 ​ $ 1,614 ​ Interest costs on projected benefit obligations (a) ​ 1,072 ​ 1,127 ​ Expected return on plan assets (a) ​ (1,843) ​ (1,598) ​ Expected administrative expenses ​ 104 ​ 110 ​ Amortization of prior service cost (a) ​ — ​ 50 ​ Amortization of unrecognized net loss (a) ​ 367 ​ 164 ​ Net periodic pension cost ​ $ 1,392 ​ $ 1,467 ​ ​ ​ ​ ​ ​ ​ ​ ​ (a) The components of net periodic pension cost other than the service cost component are included in other non-interest expense. Net periodic pension benefit costs include interest costs based on an assumed discount rate, the expected return on plan assets based on actuarially derived market-related values, and the amortization of net actuarial losses. Net periodic postretirement benefit costs include service costs, interest costs based on an assumed discount rate, and the amortization of prior service credits and net actuarial gains. Differences between expected and actual results in each year are included in the net actuarial gain or loss amount, which is recognized in other comprehensive income. The net actuarial gain or loss in excess of a 10% corridor is amortized in net periodic benefit cost over the average remaining service period of active participants in the pension plan. The prior service credit is amortized over the average remaining service period to full eligibility for participating employees expected to receive benefits.

Earnings per Share
Earnings per Share	(11) Earnings per Share Stock Dividend On July 1, 2021, the Company paid a special stock dividend of 4% to common shareholders of record at the close of business on June 15, 2021. For all periods presented, share information, including basic and diluted earnings per share, has been adjusted retroactively to reflect this change. Basic earnings per share is computed by dividing income available to shareholders by the weighted average number of shares outstanding during the year. Diluted earnings per share gives effect to all dilutive potential shares that were outstanding during the year. Presented below is a summary of the components used to calculate basic and diluted earnings per common share, which have been restated for all stock dividends: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended June 30, ​ Six Months Ended June 30, ​ (dollars in thousands, except per share data) 2021 2020 2021 2020 ​ Basic earnings per share: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Net income available to shareholders ​ $ 4,892 ​ $ 3,282 ​ $ 10,731 ​ $ 4,150 ​ Average shares outstanding ​ ​ 6,616,975 ​ ​ 6,740,147 ​ ​ 6,617,171 ​ ​ 6,752,418 ​ Basic earnings per share ​ $ 0.74 ​ $ 0.49 ​ $ 1.62 ​ $ 0.61 ​ Diluted earnings per share: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Net income available to shareholders ​ $ 4,892 ​ $ 3,282 ​ $ 10,731 ​ $ 4,150 ​ Average shares outstanding ​ 6,616,975 ​ 6,740,147 ​ 6,617,171 ​ 6,752,418 ​ Diluted earnings per share ​ $ 0.74 ​ ​ 0.49 ​ $ 1.62 ​ ​ 0.61 ​ ​ Repurchase Program In 2019, the Company's Board of Directors authorized the purchase of up to $5.0 million market value of the Company's common stock.

Fair Value Measurements
Fair Value Measurements	(12) Fair Value Measurements Fair value represents the amount expected to be received to sell an asset or paid to transfer a liability in its principal or most advantageous market in an orderly transaction between market participants at the measurement date. Depending on the nature of the asset or liability, the Company uses various valuation methodologies and assumptions to estimate fair value. The measurement of fair value under U.S. GAAP uses a hierarchy intended to maximize the use of observable inputs and minimize the use of unobservable inputs. This hierarchy uses three levels of inputs to measure the fair value of assets and liabilities as follows. The fair value hierarchy is as follows: Level 1 – Inputs are unadjusted quoted prices for identical assets or liabilities in active markets. A quoted price in an active market provides the most reliable evidence of fair value and is used to measure fair value whenever available. A contractually binding sales price also provides reliable evidence of fair value. Level 2 – Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets and liabilities in active markets, such as interest rates and yield curves that are observable at commonly quoted intervals. Level 3 – Inputs are unobservable inputs for the asset or liability and significant to the fair value. These may be internally developed using the Company’s best information and assumptions that a market participant would consider. In accordance with fair value accounting guidance, the Company measures, records, and reports various types of assets and liabilities at fair value on either a recurring or non-recurring basis in the Consolidated Financial Statements. Nonfinancial assets measured at fair value on a non-recurring basis would include foreclosed real estate, long-lived assets, and core deposit intangible assets, which are reviewed when circumstances or other events indicate that impairment may have occurred. Valuation Methods for Assets and Liabilities Measured at Fair Value on a Recurring Basis Following is a description of the Company’s valuation methodologies used for assets and liabilities recorded at fair value on a recurring basis: Available-for-Sale Securities The fair value measurements of the Company’s investment securities are determined by a third-party pricing service which considers observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other things. The fair value measurements are subject to independent verification to another pricing source by management each quarter for reasonableness. Equity securities with readily determinable fair values are recorded at fair value, with changes in fair value reflected in earnings. The Company uses level 1 inputs to value equity securities that are traded in active markets. Equity securities that do not have readily determinable fair values are carried at cost and are periodically assessed for impairment. Equity securities that are not actively traded are classified in level 2. Mortgage Servicing Rights The fair value of mortgage servicing rights is based on the discounted value of estimated future cash flows utilizing contractual cash flows, servicing rate, constant prepayment rate, servicing cost, and discount rate factors. Accordingly, the fair value is estimated based on a valuation model that calculates the present value of estimated future net servicing income. The model incorporates assumptions that market participants use in estimating future net servicing income, including estimates of prepayment speeds, market discount rates, cost to service, float earnings rates, and other ancillary income, including late fees. The valuation models estimate the present value of estimated future net servicing income. The Company classifies its servicing rights as Level 3. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Value Measurements ​ ​ ​ ​ ​ Quoted Prices ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ in Active ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Markets for ​ Other ​ Significant ​ ​ ​ ​ ​ Identical ​ Observable ​ Unobservable ​ ​ ​ ​ ​ Assets ​ Inputs ​ Inputs (in thousands) Fair Value (Level 1) (Level 2) (Level 3) June 30, 2021 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. Treasury ​ $ 3,034 ​ $ 3,034 ​ — $ — U.S. government and federal agency obligations ​ 2,068 ​ — ​ 2,068 — U.S. government-sponsored enterprises ​ 19,495 ​ — ​ 19,495 — Obligations of states and political subdivisions ​ 106,245 ​ — ​ 106,245 — Mortgage-backed securities ​ 134,638 ​ — ​ 134,638 — Other debt securities ​ ​ 9,289 ​ ​ — ​ ​ 9,289 ​ ​ — Bank-issued trust preferred securities ​ ​ 1,244 ​ ​ — ​ ​ 1,244 ​ ​ — Equity securities ​ ​ 45 ​ ​ 45 ​ ​ — ​ ​ — Mortgage servicing rights ​ 2,775 ​ — ​ — 2,775 Total ​ $ 278,833 ​ $ 3,079 ​ $ 272,979 $ 2,775 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2020 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. Treasury ​ $ 2,798 ​ $ 2,798 ​ — $ — U.S. government and federal agency obligations ​ 11,929 ​ — ​ 11,929 — U.S. government-sponsored enterprises ​ 22,874 ​ — ​ 22,874 — Obligations of states and political subdivisions ​ 58,744 ​ — ​ 58,744 — Mortgage-backed securities ​ 90,112 ​ — ​ 90,112 — Other debt securities ​ ​ 10,344 ​ ​ — ​ ​ 10,344 ​ ​ — Bank-issued trust preferred securities ​ ​ 1,229 ​ ​ — ​ ​ 1,229 ​ ​ — Equity securities ​ ​ 32 ​ ​ 32 ​ ​ — ​ ​ — Mortgage servicing rights ​ 2,445 ​ — ​ — 2,445 Total ​ $ 200,507 ​ $ 2,830 ​ $ 195,232 $ 2,445 ​ The changes in Level 3 assets and liabilities measured at fair value on a recurring basis are summarized as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Value Measurements Using ​ Fair Value Measurements Using ​ ​ (Level 3) ​ (Level 3) ​ ​ Mortgage Servicing Rights ​ Mortgage Servicing Rights ​ ​ Three Months Ended June 30, ​ Six Months Ended June 30, (in thousands) 2021 2020 2021 2020 Balance at beginning of period ​ $ 2,494 ​ $ 2,274 ​ $ 2,445 ​ $ 2,482 Total gains or (losses) (realized/unrealized): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Included in earnings ​ 158 ​ (250) ​ 38 ​ (525) Included in other comprehensive income ​ — ​ — ​ — ​ — Purchases ​ — ​ — ​ — ​ — Sales ​ — ​ — ​ — ​ — Issues ​ 123 ​ 121 ​ 292 ​ 188 Settlements ​ — ​ — ​ — ​ — Balance at end of period ​ $ 2,775 ​ $ 2,145 ​ $ 2,775 ​ $ 2,145 ​ Valuation Methods for Assets and Liabilities Measured at Fair Value on a nonrecurring basis Following is a description of the Company’s valuation methodologies used for assets and liabilities recorded at fair value on a Non-recurring Basis: Collateral Dependent Impaired Loans While the overall loan portfolio is not carried at fair value, the Company periodically records nonrecurring adjustments to the carrying value of loans based on fair value measurements for partial charge-offs of the uncollectible portions of those loans. Nonrecurring adjustments also include certain impairment amounts for collateral dependent loans when establishing the allowance for loan losses. Such amounts are generally based on the fair value of the underlying collateral supporting the loan. In determining the value of real estate collateral, the Company relies on external and internal appraisals of property values depending on the size and complexity of the real estate collateral. The Company maintains staff that is trained to perform in-house evaluations and also review third-party appraisal reports for reasonableness. In the case of non-real estate collateral, reliance is placed on a variety of sources, including external estimates of value and judgments based on the experience and expertise of internal specialists. Values of all loan collateral are regularly reviewed by a senior loan committee. Because many of these inputs are not observable, the measurements are classified as Level 3. As of June 30, 2021, the Company identified $31.8 million in collateral dependent impaired loans that had specific allowances for losses aggregating $5.0 million. Related to these loans, there were $11,000 and $34,000 in charge-offs recorded during the three and six months ended June 30, 2021, respectively. As of June 30, 2020, the Company identified $7.0 million in collateral dependent impaired loans that had specific allowances for losses aggregating $0.4 million. Related to these loans, there were $37,000 and $92,000 in charge-offs recorded during the three and six months ended June 30, 2020, respectively. Other Real Estate and Foreclosed Assets Other real estate owned (OREO) and foreclosed assets consisted of loan collateral that has been repossessed through foreclosure. This collateral is comprised of commercial and residential real estate and other non-real estate property, including autos, manufactured homes, and construction equipment. Subsequent to foreclosure, these assets initially are carried at fair value of the collateral less estimated selling costs. Fair value, when recorded, is generally based upon appraisals by approved, independent state-certified appraisers. Like impaired loans, appraisals on OREO may be discounted based on the Company’s historical knowledge, changes in market conditions from the time of appraisal or other information available. During the holding period, valuations are updated periodically, and the assets may be written down to reflect a new cost basis. Because many of these inputs are not observable, the measurements are classified as Level 3. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Value Measurements Using ​ ​ ​ ​ ​ Quoted Prices ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ in Active ​ ​ ​ ​ ​ ​ ​ Three Months ​ Six Months ​ ​ ​ ​ ​ Markets for ​ Other ​ Significant ​ Ended ​ Ended ​ ​ ​ ​ ​ Identical ​ Observable ​ Unobservable ​ June 30, ​ June 30, ​ ​ Total ​ Assets ​ Inputs ​ Inputs ​ Total Gains ​ Total Gains (in thousands) Fair Value (Level 1) (Level 2) (Level 3) (Losses)* (Losses)* June 30, 2021 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Collateral dependent impaired loans: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial, financial, & agricultural ​ $ 3,976 ​ $ — ​ $ — ​ $ 3,976 $ — $ — Real estate mortgage - residential ​ 359 ​ — ​ — ​ 359 (3) (3) Real estate mortgage - commercial ​ 22,420 ​ — ​ — ​ 22,420 (2) (25) Installment and other consumer ​ — ​ — ​ — ​ — (6) (6) Total ​ $ 26,755 ​ $ — ​ $ — ​ $ 26,755 $ (11) $ (34) Other real estate and repossessed assets ​ $ 11,938 ​ $ — ​ $ — ​ $ 11,938 $ 14 $ (59) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, 2020 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Collateral dependent impaired loans: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial, financial, & agricultural ​ $ 2,408 ​ $ — ​ $ — ​ $ 2,408 $ — $ — Real estate construction - commercial ​ 837 ​ — ​ — ​ 837 — — Real estate mortgage - residential ​ 2,031 ​ — ​ — ​ 2,031 (32) (51) Real estate mortgage - commercial ​ 1,304 ​ — ​ — ​ 1,304 (2) (24) Installment and other consumer ​ 11 ​ — ​ — ​ 11 (3) (17) Total ​ $ 6,591 ​ $ — ​ $ — ​ $ 6,591 $ (37) $ (92) Other real estate and repossessed assets ​ $ 12,520 ​ $ — ​ $ — ​ $ 12,520 $ 213 $ 199 * Total losses reported for other real estate and foreclosed assets includes charge-offs, valuation write downs, and net losses taken during the periods reported.

Fair Value of Financial Instruments
Fair Value of Financial Instruments	(13) Fair Value of Financial Instruments The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate such value: Loans Fair values are estimated for portfolios with similar financial characteristics. Loans are segregated by type, such as commercial, real estate, and consumer. Each loan category is further segmented into fixed and variable interest rate categories. The fair value of loans, or exit price, is estimated by using the future value of discounted cash flows using comparable market rates for similar types of loan products and adjusted for market factors. The discount rates used are estimated using comparable market rates for similar types of loan products adjusted to be commensurate with the credit risk, overhead costs, and optionality of such instruments. Loans Held for Sale Loans originated and intended to be sold in the secondary market, generally 1-4 family residential mortgage loans, are carried, in aggregate, at the lower of cost or estimated fair value. The estimated fair value measurements of loans held for sale are management's best estimate of fair value, which is primarily based on quoted market prices for similar loans in the secondary market. Investment Securities A detailed description of the fair value measurement of the debt instruments in the available-for-sale sections of the investment security portfolio is provided in the Fair Value Measurement Investment Securities Other Investment Securities Other investment securities include equity securities with readily determinable fair values and other investment securities that do not have readily determinable fair values. Investments in FHLB stock, and MIB bankers bank stock, that do not have readily determinable fair values, are required for membership in those organizations. Equity securities that are not actively traded are classified in level 2. Equity securities with readily determinable fair values are recorded at fair value, with changes in fair value reflected in earnings. Equity securities that do not have readily determinable fair values are carried at cost and are periodically assessed for impairment. The Company uses level 1 inputs to value equity securities that are traded in active markets. Federal Funds Sold, Cash, and Due from Banks The carrying amounts of short-term federal funds sold, interest earning deposits with banks, and cash and due from banks approximate fair value. Federal funds sold classified as short-term generally mature in 90 days or less. Certificates of Deposit in Other Banks Certificates of deposit are other investments made by the Company with other financial institutions that are carried at cost which is equal to fair value. Cash Surrender Value - Life Insurance The fair value of Bank-owned life insurance (BOLI) approximates the carrying amount. Upon liquidation of these investments, the Company would receive the cash surrender value which equals the carrying amount. Accrued Interest Receivable and Payable For accrued interest receivable and payable, the carrying amount is a reasonable estimate of fair value because of the short maturity for these financial instruments. Deposits The fair value of deposits with no stated maturity, such as noninterest-bearing demand, NOW accounts, savings, and money market, is equal to the amount payable on demand. The fair value of time deposits is based on the discounted value of contractual cash flows. The discount rate is estimated using the rates currently offered for deposits of similar remaining maturities. Federal funds purchased and Securities Sold under Agreements to Repurchase For Federal funds purchased and securities sold under agreements to repurchase, the carrying amount is a reasonable estimate of fair value, as such instruments reprice in a short time period. Subordinated Notes and Other Borrowings The fair value of subordinated notes and other borrowings is based on the discounted value of contractual cash-flows. The discount rate is estimated using the rates currently offered for other borrowed money of similar remaining maturities. ​ A summary of the carrying amounts and fair values of the Company’s financial instruments at June 30, 2021 and December 31, 2020 is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, 2021 ​ ​ ​ ​ ​ ​ ​ ​ Fair Value Measurements ​ ​ ​ ​ ​ ​ ​ ​ ​ Quoted Prices ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ in Active ​ ​ ​ Net ​ ​ ​ ​ ​ ​ ​ Markets for Other Significant ​ June 30, 2021 Identical Observable Unobservable ​ Carrying Fair Assets Inputs Inputs (in thousands) amount value (Level 1) (Level 2) (Level 3) Assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Cash and due from banks ​ $ 17,920 ​ $ 17,920 ​ $ 17,920 ​ $ — $ — Federal funds sold and overnight interest-bearing deposits ​ 58,514 ​ 58,514 ​ 58,514 ​ — ​ — Certificates of deposit in other banks ​ 7,165 ​ 7,165 ​ 7,165 ​ — ​ — Available-for-sale securities ​ 276,013 ​ 276,013 ​ 3,034 ​ 272,979 ​ — Other investment securities ​ 6,009 ​ 6,009 ​ 45 ​ 5,964 ​ — Loans, net ​ 1,275,159 ​ 1,299,656 ​ — ​ — ​ 1,299,656 Loans held for sale ​ ​ 2,487 ​ ​ 2,565 ​ ​ — ​ ​ — ​ ​ 2,565 Cash surrender value - life insurance ​ 2,480 ​ 2,480 ​ — ​ 2,480 ​ — Accrued interest receivable ​ 6,849 ​ 6,849 ​ 6,849 ​ — ​ — Total ​ $ 1,652,596 ​ $ 1,677,171 ​ $ 93,527 ​ $ 281,423 $ 1,302,221 Liabilities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Deposits: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Non-interest bearing demand ​ $ 433,288 ​ $ 433,288 ​ $ 433,288 ​ $ — $ — Savings, interest checking and money market ​ 704,236 ​ 704,236 ​ 704,236 ​ — ​ — Time deposits ​ 243,477 ​ 244,871 ​ — ​ — ​ 244,871 Federal funds purchased and securities sold under agreements to repurchase ​ 32,018 ​ 32,018 ​ 32,018 ​ — ​ — Federal Home Loan Bank advances and other borrowings ​ 93,554 ​ 95,314 ​ — ​ 95,314 ​ — Subordinated notes ​ 49,486 ​ 41,424 ​ — ​ 41,424 ​ — Accrued interest payable ​ 376 ​ 376 ​ 376 ​ — ​ — Total ​ $ 1,556,435 ​ $ 1,551,527 ​ $ 1,169,918 ​ $ 136,738 $ 244,871 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2020 ​ ​ ​ ​ ​ ​ ​ ​ Fair Value Measurements ​ ​ ​ ​ ​ ​ ​ ​ Quoted Prices ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ in Active ​ ​ ​ Net ​ ​ ​ ​ ​ ​ ​ Markets for Other Significant ​ ​ December 31, 2020 Identical Observable Unobservable ​ Carrying Fair Assets Inputs Inputs (in thousands) amount value (Level 1) (Level 2) (Level 3) Assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Cash and due from banks ​ $ 19,235 ​ $ 19,235 ​ $ 19,235 ​ $ — $ — Federal funds sold and overnight interest-bearing deposits ​ 161,128 ​ 161,128 ​ 161,128 ​ — ​ — Certificates of deposit in other banks ​ 9,376 ​ 9,376 ​ 9,376 ​ — ​ — Available-for-sale securities ​ 198,030 ​ 198,030 ​ 2,798 ​ 195,232 ​ — Other investment securities ​ 6,353 ​ 6,353 ​ 32 ​ 6,321 ​ — Loans, net ​ 1,268,854 ​ 1,288,677 ​ — ​ — ​ 1,288,677 Loans held for sale ​ ​ 5,099 ​ ​ 5,279 ​ ​ — ​ ​ — ​ ​ 5,279 Cash surrender value - life insurance ​ 2,451 ​ 2,451 ​ — ​ 2,451 ​ — Accrued interest receivable ​ 6,640 ​ 6,640 ​ 6,640 ​ — ​ — Total ​ $ 1,677,166 ​ $ 1,697,169 ​ $ 199,209 ​ $ 204,004 $ 1,293,956 Liabilities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Deposits: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Non-interest bearing demand ​ $ 382,492 ​ $ 382,492 ​ $ 382,492 ​ $ — $ — Savings, interest checking and money market ​ 723,808 ​ 723,808 ​ 723,808 ​ — ​ — Time deposits ​ 277,306 ​ 279,569 ​ — ​ — ​ 279,569 Federal funds purchased and securities sold under agreements to repurchase ​ 45,154 ​ 45,154 ​ 45,154 ​ — ​ — Federal Home Loan Bank advances and other borrowings ​ 106,674 ​ 110,121 ​ — ​ 110,121 ​ — Subordinated notes ​ 49,486 ​ 40,929 ​ — ​ 40,929 ​ — Accrued interest payable ​ 837 ​ 837 ​ 837 ​ — ​ — Total ​ $ 1,585,757 ​ $ 1,582,910 ​ $ 1,152,291 ​ $ 151,050 $ 279,569 ​ Off-Balance Sheet Financial Instruments The fair value of commitments to extend credit and standby letters of credit is estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements, the likelihood of the counterparties drawing on such financial instruments, and the present creditworthiness of such counterparties. The Company believes such commitments have been made on terms that are competitive in the markets in which it operates. Limitations The fair value estimates provided are made at a point in time based on market information and information about the financial instruments. Because no market exists for a portion of the Company’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and, therefore, cannot be determined with precision. Changes in assumptions could significantly affect the fair value estimates.

Commitments and Contingencies
Commitments and Contingencies	(14) Commitments and Contingencies The Company issues financial instruments with off-balance-sheet risk in the normal course of business of meeting the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. These instruments may involve, to varying degrees, elements of credit and interest rate risk in excess of the amounts recognized in the consolidated balance sheets. The Company’s extent of involvement and maximum potential exposure to credit loss in the event of non-performance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual amount of these instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for financial instruments included on its consolidated balance sheets. At June 30, 2021, no amounts have been accrued for any estimated losses for these financial instruments. The contractual amount of off-balance-sheet financial instruments were as follows as of the dates indicated: ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, ​ December 31, (in thousands) 2021 2020 Commitments to extend credit ​ $ 271,115 ​ $ 264,528 Commitments to originate residential first and second mortgage loans ​ 22,488 ​ 51,270 Standby letters of credit ​ 3,625 ​ 125,800 Total ​ $ 297,228 ​ $ 441,598 ​ Commitments Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since certain of the commitments and letters of credit are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the customer. Collateral held varies, but may include accounts receivable, inventory, furniture and equipment, and real estate. Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third-party. These standby letters of credit are primarily issued to support contractual obligations of the Company’s customers. The approximate remaining term of standby letters of credit range from one month to five years at June 30, 2021. Pending Litigation The Company and its subsidiaries are defendants in various legal actions incidental to the Company’s past and current business activities. Based on the Company’s analysis, and considering the inherent uncertainties associated with litigation, management does not believe that it is reasonably possible that these legal actions will materially adversely affect the Company’s consolidated financial condition or results of operations in the near term.
