Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 1 Summary of Significant Accounting Policies Summary of Operations Basis of Presentation Use of Estimates Cash and Cash Equivalents Investment in Debt Securities Financial Instruments – Credit Losses For available for sale debt securities in an unrealized loss position, the entire loss in fair value is required to be recognized in current earnings if the Company intends to sell the securities or believes it likely that it will be required to sell the security before the anticipated recovery. If neither condition is met, and the Company does not expect to recover the amortized cost basis, the Company determines whether the decline in fair value resulted from credit losses or other factors. If the assessment indicates that a credit loss exists, the present value of cash flows expected to be collected is 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 has occurred, and an allowance for credit losses is recorded. The allowance for credit losses is limited by the amount that the fair value is less than the amortized cost basis. Any impairment not recorded through the provision for credit losses would be recognized in other comprehensive income. Changes in the allowance for credit losses would be recorded as a provision for credit losses on the consolidated statements of income. Losses would be charged against the allowance for credit losses on securities when management believes the uncollectibility of an available for sale security is confirmed or when either of the conditions regarding intent or requirement to sell is met. Prior to the adoption of ASU 2016 -13 as of January 1, 2020, the Company evaluated a decline in the fair value of any available-for-sale security below cost to determine whether the decline was deemed other than temporary and, if so, would result in a charge to earnings and the establishment of a new cost basis for the security. To determine whether impairment was other than temporary, the Company considered guidance provided in the FASB ASC Topic 320, Investments – Debt and Equity Securities. When determining whether a debt security was other-than-temporarily impaired, the Company assessed whether it had the intent to sell the security and whether it was more likely than not that the Company would be required to sell prior to recovery of the amortized cost basis. Evidence considered in this assessment included the reasons for impairment, the severity and duration of the impairment, changes in value subsequent to year-end and forecasted performance of the investee. Premiums and discounts are amortized or accreted to interest income over the estimated lives of the securities using the level-yield method. Interest income is recognized when earned. Gains and losses are calculated using the specific identification method. Loans 40 Table of Contents both principal and interest and/or the borrower demonstrates the ability to pay and remain current. Loan origination and commitment fees on originated loans, net of certain direct loan origination costs, are deferred and amortized to interest income using the level-yield method over the estimated lives of the related loans. Allowance for Credit Losses Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments The ACL is a valuation account that is deducted from the amortized cost basis to present the net amount expected to be collected on the loans. Loans are charged off against the ACL when management believes the uncollectibility of a loan balance is confirmed. Expected recoveries for amounts previously charged off and expected to be charged off do not exceed the aggregate of amounts previously charged off and expected to be charged off. Management estimated the allowance balance using relevant available information from internal and external sources, relating to past events, current conditions and reasonable and supportable forecasts based on economic factors, such as GDP. Historical credit loss experience, of both the Company and similar peer banks, provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made for lending management experience, asset quality trends, borrower’s ability to pay, collateral, and other environmental factors. The ACL is measured on a collective pool basis when similar risk characteristics exist. Management believes the ACL is adequate to absorb expected losses in the loan portfolio. Loans The ACL is measured on a collective pool basis when similar risk characteristics exist. The Company has identified the following portfolio segments: Commercial & Industrial (“C&I”) Commercial Real Estate (“CRE”) Faith-based CRE Construction and Land Development The ACL is calculated as the difference between the amortized cost basis and the projections from the weighted-average remaining maturity ("WARM") model that the Company developed. The WARM model utilizes an attrition analysis, including events such as payoffs, matured loans, and renewals in the borrowers’ control, to anticipate the length of time it would take for each portfolio segment to runoff. Management incorporates a one year GDP forecast and an immediate reversion to peer historical loss rates to determine the annual charge off rates over the estimated life of the loans. After the reasonable and supportable forecast period, the model reverts to long-run historical average loss rates of its peers. However, for the faith-based CRE ACL, beyond the reasonable and supportable forecast period, loss rates are reverted immediately to the Company’s long-run historical averages, as this represents a unique loan segment to the peer portfolios. The economic forecast is based on management’s assessment of the length and pattern of the current economic cycle. The resulting annual charge off rate determined for each year in the WARM model is applied to the loan balances estimated in the attrition analysis. Management accounts for the inherent uncertainty of the underlying economic forecast by reviewing forecast scenarios. Additionally, the ACL calculation includes subjective adjustments for qualitative risk factors that are likely to cause estimated 41 Table of Contents credit losses to differ from historical experience. These qualitative adjustments may increase or reduce reserve levels and include adjustments for lending management experience and risk tolerance, loan review and audit results, asset quality and portfolio trends, loan portfolio growth and loan concentrations. The Company has elected to exclude accrued interest receivable ("AIR") from the allowance for credit losses calculation. When a loan is placed on non-accrual, any recorded AIR is reversed against interest income. The determination and application of the ACL accounting policy involves judgments, estimates, and uncertainties that are subject to change. Changes in these assumptions, estimates or the conditions surrounding them may have a material impact on the Company’s financial condition, liquidity or results of operations. Various regulatory agencies, as an integral part of the examination process, periodically review the ACL. Such agencies may require the Company to recognize additions to the ACL or reserve increases to adversely graded classified loans based on information available to them at the time of their examinations. The ACL is decreased by net charge-offs and is increased by provisions for credit losses that are charged to the consolidated statements of operations. Charge-offs, if any, are typically measured for each loan based on a thorough analysis of the most probable source of repayment, such as the present value of the loan’s expected future cash flows, the loan’s estimated fair value, or the estimated fair value of the underlying collateral less costs of disposition for collateral-dependent loans. When it is determined that specific loans, or portions thereof, are uncollectible, these amounts are charged off against the ACL. Unfunded loan commitments In addition to the ACL for funded loans, the Company maintains reserves to cover the risk of loss associated with off-balance sheet unfunded loan commitments. The allowance for off-balance sheet credit losses is maintained within other liabilities in the statements of financial condition. Under the CECL framework, adjustments to this liability are recorded as provision for credit losses in the consolidated statements of operations. Unfunded loan commitment balances are evaluated by loan segment. In order to establish the required level of reserve, the Company applies average historical utilization rates and ACL loan model loss rates for each loan segment to the outstanding unfunded commitment balances. Investment securities Management evaluates all investments in an unrealized loss position on a quarterly basis, and more frequently when economic or market conditions warrant such evaluation. If the Company has the intent to sell the security or it is more likely than not that the Company will be required to sell the security, the security is written down to fair value and the entire loss is recorded in earnings. If either of the above criteria is not met, the Company will evaluate whether the decline in fair value is the result of credit losses or other factors. In making the assessment, the Company may consider various factors including the extent to which fair value is less than amortized cost, performance on any underlying collateral, downgrades in the ratings of the security by a rating agency, the failure of the issuer to make scheduled interest or principal payments and adverse conditions specifically related to the security. If the assessment indicates that a credit loss exists, the present value of cash flows expected to be collected are compared to the amortized cost basis of the security and any excess is recorded as an allowance for credit loss. For U.S. agency-backed securities where the risk of nonpayment of the amortized cost basis is zero, the Company will not measure expected credit losses on these securities. When the loss is not considered a result of credit loss, the cost basis of the security is written down to fair value, with the loss charge recognized in AOCI. Credit losses are not estimated for AIR from investment securities as interest deemed uncollectible is written off through interest income. Allowance for Loan Losses Estimated credit losses inherent in the remainder of the portfolio were estimated in accordance with FASB ASC 450, Contingencies. These loans were segmented into groups based on similar risk characteristics. Historical loss rates for each risk group, which were updated quarterly, were generally quantified using all recorded loan charge-offs and recoveries over a prescribed look-back period. These historical loss rates for each risk group were used as the starting point to determine the level of the allowance. The Company’s methodology incorporated an estimated loss emergence period for each risk group. The loss emergence period was the period of time from when a borrower experienced a loss event and when the actual loss was recognized in the financial statements, generally at the time of initial charge-off of the loan balance. The Company’s methodology also included qualitative risk factors that allowed management to adjust its estimates of losses based on the most recent information available and to address other limitations in the quantitative component that was based on historical loss rates. Such risk factors were generally reviewed and updated quarterly, as appropriate, and were adjusted to reflect changes in national and local economic conditions and developments, the volume and severity of delinquent and internally classified loans, loan concentrations, assessment of trends in collateral values, assessment of changes in borrowers’ financial stability, and changes in lending policies and procedures, including underwriting standards and collections, charge-off and recovery practices. 42 Table of Contents Management believed the ALLL was adequate to absorb probable losses in the loan portfolio. Additionally, various regulatory agencies, as an integral part of their examination process, periodically reviewed the Company’s ALLL. Such agencies may have required the Company to increase the ALLL based on information available to them at the time of their examinations. Impairment of Loans Foreclosed Assets Premises and Equipment Intangible Assets Periodically, the Company reviews intangible assets for events or changes in circumstances that may indicate that the carrying amount of the assets may not be recoverable. Based on those reviews, adjustments of recorded amounts have not been required. Non-marketable Equity Investments Treasury Stock Comprehensive Income Information Services Revenue Income Taxes 43 Table of Contents Company and its subsidiaries file U.S. federal and certain state income tax returns on a consolidated basis. In addition, certain state jurisdictions are filed on a separate company basis by the Company or its subsidiaries. The Company recognizes and measures income tax benefits using a two-step model: 1) a tax position must be more likely than not to be sustained based solely on its technical merits in order to be recognized; and 2) the benefit must be measured as the largest dollar amount of that position that is more likely than not to be sustained upon settlement. The difference between the benefit recognized for a tax position in this model and the tax benefit claimed on a tax return is treated as an unrecognized tax benefit. The Company recognizes income tax related interest and penalties in income tax expense. Earnings Per Share Stock-Based Compensation Accounting for Stock Options and Other Stock-based Compensation Pension Plans Compensation – Retirement Benefits Fair Value Measurements Fair Value Measurements and Disclosures Impact of New and Not Yet Adopted Accounting Pronouncements In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments The ASU required measurement and recognition of expected credit losses for financial instruments held at amortized cost, which include allowances for credit losses expected over the life of the portfolio, rather than incurred losses, which include allowances for current known and inherent losses within the portfolio. Under this standard, the Company is required to hold an allowance equal to the expected life-of-loan losses on the loan portfolio. It also applies to off-balance sheet credit exposures such as loan commitments, standby letters of credit and other similar instruments. In addition, ASU 2016-13 made changes to the accounting for available-for-sale debt securities. The Company adopted ASU 2016-13 using a modified retrospective approach. Results for annual reporting periods beginning after January 1, 2020 are presented under ASU 2016-13 while prior period amounts continue to be reported in accordance with 44 Table of Contents previously applicable GAAP. Upon adoption, the Company recognized increases of $723,000 in the allowance for credit losses and $402,000 in the reserve for unfunded commitments, with a corresponding reduction to retained earnings, net of tax, of $856,000. No credit loss allowance was required upon adoption for the investment securities portfolio. Consistent with the provisions of the CARES Act, results for quarterly reporting periods beginning after December 31, 2020 in the Company’s Form 10-Q will be presented under ASU 2016-13 while prior quarterly period amounts continue to be reported in accordance with previously applicable GAAP.

The declaration of a global pandemic indicates that almost all public commerce and related business activities must be, to varying degrees, curtailed with the goal of decreasing the rate of new infections. This response to the COVID-19 pandemic has resulted in an unprecedented slow-down in economic activity and a related increase in unemployment. In late fiscal 2020, vaccines for combatting COVID-19 were approved by health agencies and began to be administered. However, initial quantities of vaccines are limited and vaccine distributions, controlled by local authorities, are being allocated, generally first to front-line health care workers and other essential workers and next to those members of individual populations believed most susceptible to severe effects from COVID-19. The timeline of full administration of the COVID-19 vaccines is uncertain and fluctuating, but is widely thought to be unlikely to occur in most jurisdictions until mid to late 2021. The impact of COVID-19, including the impact of restrictions imposed to combat its spread, could result in additional and prolonged business closures, work restrictions and activity restrictions. The Company has evaluated subsequent events after the consolidated balance sheet date of December 31, 2020 and the breadth of the impact of the global presence of COVID-19 on the Company’s business is currently unknown. The Company is closely monitoring developments related to COVID-19 checking regularly for updated information and recommendations from the WHO and the CDC, from national, state, and local governments, and evaluating courses of action being taken by peers. The duration and severity of the effect of COVID-19 on economic, market and business conditions and the timeline and shape of recovery from the pandemic remain uncertain. At this time, the Company remains subject to heightened business, operational, market, credit and other risks related to the COVID-19 pandemic, including, but not limited to, those discussed below, which may have an adverse effect on business, financial condition and results of operations. Financial position and results of operations - The global health crisis caused by COVID-19 has and will continue to negatively impact business activity throughout the world. The COVID-19 outbreak and associated counter-acting measures implemented by governments around the world, as well as increased business uncertainty, have had, and continue to have, an adverse impact on the Company’s financial results and are discussed in more detail below. Although in various locations certain activity restrictions have been relaxed with some success, many states and localities are experiencing significant increases in the number of COVID-19 cases, prompting a reinstatement of prior activity restrictions in some locations and the need for additional aid and other forms of relief for affected individuals, businesses and other entities. When and if COVID-19 is demonstrably contained, the Company anticipates a rebound in economic activity; however, any such rebound is contingent upon the rate and effectiveness of the containment efforts deployed by federal, state, and local governments. In light of the evolving health, social, economic and business environment, governmental regulations or mandates, and business disruptions that have occurred and could continue to occur, the aggregate impact that COVID-19 could have on the Company’s financial condition and operating results remains highly uncertain. In response to COVID-19, the Federal Reserve has taken action to lower the Federal Funds rate, which has adversely affected interest income and therefore, the Company’s results of operations and financial condition. The Federal Reserve has continued 45 Table of Contents its commitment to this approach, indicating that the target Federal Funds rate would remain at current levels until the economy is in a more stable employment and price-stability position. To the extent the business disruption continues for an extended period, additional cost control actions will be considered. Future asset impairment charges, increases in allowance for credit losses, or restructuring charges could be more likely and will be dependent on the severity and duration of this crisis and its effect on the Company’s borrowers. For payment processing services, business closures, including constrictions in the manufacturing sector, have led to a decrease in the number of transactions and dollars processed due to the decline in customers’ business activity. In addition, the dampened demand for oil and resulting plummet in oil prices has had, and can continue to have, a negative effect on both the number of freight transactions processed and the dollar amount of invoices processed. Other financial impact could occur though such potential impact is unknown at this time. Capital and liquidity - While the Company believes that it has sufficient capital to withstand an extended economic recession brought about by COVID-19, its reported and regulatory capital ratios could be adversely impacted by future financial losses. The Company maintains access to multiple sources of liquidity. If funding costs are elevated for an extended period of time, it could have an adverse effect on the Company’s net interest margin. If an extended recession caused large numbers of the Bank’s customers to draw down deposits, the Company might become more reliant on more expensive sources of funding. Asset valuation - Currently, the Company does not expect COVID-19 to affect its ability to fairly value the assets on its balance sheet; however, this could change in future periods. While certain valuation assumptions and judgments will change to account for pandemic-related circumstances such as widening credit spreads, the Company does not anticipate significant changes in methodology used to determine the fair value of assets measured in accordance with GAAP. The economic slowdown as a result of COVID-19 could cause a further and sustained decline in the Company’s stock price or the occurrence of what management would deem to be a triggering event that could, under certain circumstances, necessitate a goodwill or intangible asset impairment test and result in an impairment charge being recorded for that period. In the event that the Company concludes that all or a portion of its goodwill is impaired, a non-cash charge for the amount of such impairment would be recorded to earnings. Such a charge would have no impact on tangible capital or regulatory capital. Processes, controls and business continuity - In accord with its federally mandated Pandemic Plan and Business Continuity Plan, Cass has deployed its remote workforce program. Most Cass employees around the globe are now working and conducting business remotely. Employees necessary to oversee certain business coordination activities or to conduct essential physical activities such as mail handling and scanning operations, remain in offices. In addition, employees are now being permitted to return to the offices on a voluntary basis. Employees are required to report any exposure or diagnosis and must adhere to the defined safety protocol to enter the offices. In the past several years, Cass has invested in sophisticated technology initiatives that enable employees to operate remotely with full system(s) access along with unified and transparent voice and electronic communications capabilities, ensuring seamless service delivery. The Company cannot predict when or how it will fully lift the actions put in place as part of the Business Continuity Plan, including work from home requirements and travel restrictions. Cass does not believe the work from home protocol has materially adversely impacted internal controls, financial reporting systems, or operations.

Capital Requirements and Regula

Capital Requirements and Regulatory Restrictions	12 Months Ended

Broker-Dealer, Net Capital Requirement, SEC Regulation [Abstract]
Capital Requirements and Regulatory Restrictions	Note 2 Capital Requirements and Regulatory Restrictions The Company and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can result in certain mandatory, and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s consolidated financial statements. Under capital adequacy guidelines, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. The Company’s and the Bank’s capital amounts and classifications are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Quantitative measures established by regulators to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios of total and Tier I capital and common equity Tier I capital to risk-weighted assets, and of Tier I capital to average assets. Management believes that as of December 31, 2020 and 2019, the Company and the Bank met all capital adequacy requirements to which they are subject. Effective July 2, 2013, the Federal Reserve Board approved final rules known as the “Basel III Capital Rules” that substantially revised the risk-based capital and leverage capital requirements applicable to bank holding companies and depository institutions, including the Company and the Bank. The Basel III Capital Rules implement aspects of the Basel III capital 46 Table of Contents framework agreed upon by the Basel Committee and incorporate changes required by the Dodd-Frank Wall Street Reform and Consumer Protection Act. Among other things, the Basel III Capital Rules establish stricter capital requirements and calculation standards, as well as more restrictive risk weightings for certain loans and facilities. The Basel III Capital Rules were effective for the Company and the Bank on January 1, 2015, subject to a phase-in period that ended on January 1, 2019. The Bank is also subject to the regulatory framework for prompt corrective action. As of December 31, 2020, the most recent notification from the regulatory agencies categorized the Bank as well-capitalized. To be categorized as well-capitalized, the Bank must maintain minimum total risk-based, common equity Tier I risk-based, Tier I risk-based, and Tier I leverage ratios as set forth in the table below. There are no conditions or events since that notification that management believes have changed the Bank’s category. The Company has traditionally paid a quarterly cash dividend to its shareholders. Subsidiary dividends can be a significant source of funds for payment of dividends by the Company to its shareholders. Banking regulations may limit the amount of dividends that may be paid. Approval by regulatory authorities is required if the effect of dividends declared would cause the regulatory capital of the Bank to fall below specified minimum levels. Approval is also required if dividends declared exceed the net profits for that year combined with the retained net profits for the preceding two years. Under the foregoing dividend restrictions and while maintaining its “well capitalized” status, at December 31, 2020, unappropriated retained earnings of $48,680,000 were available at the Bank for the declaration of dividends to the Company without prior approval from regulatory authorities. In addition to regulatory requirements and considerations, any payment of dividends in the future will depend on the Company’s earnings, financial condition and other factors considered relevant by the Company’s Board of Directors. There were no restricted funds on deposit used to meet regulatory reserve requirements at December 31, 2020 and 2019.

Investment in Securities	Note 3 Investment in Securities Investment securities available-for-sale are recorded at fair value on a recurring basis. The Company’s investment securities available-for-sale at December 31, 2020 and 2019 are measured at fair value using Level 2 valuations. The market evaluation utilizes several sources which include “observable inputs” rather than “significant unobservable inputs” and therefore falls into the Level 2 category.

Diluted earnings per share is computed by dividing net income by the sum of the weighted average number of common shares outstanding and the weighted average number of potential common shares outstanding. Under the treasury stock method, stock appreciation rights (“SARs”) are dilutive when the average market price of the Company’s common stock, combined with the effect of any unamortized compensation expense, exceeds the SAR price during a period. Anti-dilutive shares are those SARs with prices in excess of the current market value. 53 Table of Contents The calculations of basic and diluted earnings per share are as follows: December 31, (In thousands except share and per share data) 2020 2019 2018 Basic: Net income $ 25,176 $ 30,404 $ 30,268 Weighted average common shares outstanding 14,364,406 14,434,445 14,675,136 Basic earnings per share $ 1.75 $ 2.11 $ 2.06 Diluted: Net income $ 25,176 $ 30,404 $ 30,268 Weighted average common shares outstanding 14,364,406 14,434,445 14,675,136 Effect of dilutive restricted stock, performance based restricted stock (“PBRS”), and SARs 202,541 257,480 239,066 Weighted average common shares outstanding assuming dilution 14,566,947 14,691,925 14,914,202 Diluted earnings per share $ 1.73 $ 2.07 $ 2.03

Retirement Benefits [Abstract]
Employee Benefit Plans	Note 10 Employee Benefit Plans Defined Benefit Plan The Company has a noncontributory defined-benefit pension plan (the “Plan”), which covers eligible employees. Effective December 31, 2016, the Plan was closed to all new participants. Additionally, prior to the end of 2020, the Company notified existing participants that benefits would be frozen as of February 28, 2021. The freezing of the benefits reduced the projected benefit obligation by $18,322,000 at December 31, 2020. The Company accrues and makes contributions designed to fund normal service costs on a current basis using the projected unit credit with service proration method to amortize prior service costs arising from improvements in pension benefits and qualifying service prior to the establishment of the Plan over a period of approximately 30 years. A summary of the activity in the Plan’s projected benefit obligation, assets, funded status and amounts recognized in the Company’s consolidated balance sheets is as follows: (In thousands) 2020 2019 Projected benefit obligation: Balance, January 1 $ 119,827 $ 96,401 Service cost 4,329 3,554 Interest cost 3,908 4,103 Actuarial loss 15,087 18,334 Plan amendments (18,322 ) ─ Benefits paid (2,794 ) (2,565 ) Balance, December 31 $ 122,035 $ 119,827 Plan assets: Fair value, January 1 $ 94,634 $ 74,580 Actual return 14,827 15,719 Employer contribution — 6,900 Benefits paid (2,794 ) (2,565 ) Fair value, December 31 $ 106,667 $ 94,634 Funded status: Accrued pension liability $ (15,368 ) $ (25,192 ) The following represent the major assumptions used to determine the projected benefit obligation of the Plan. For 2020, 2019 and 2018, the Plan’s expected benefit cash flows were discounted using the FTSE Above Median Double-A Curve. For 2020, the Pri-2012 Mortality Table and MP-2020 Mortality Improvement Scale were used. For 2019, the Pri-2012 Mortality Table and MP-2019 Mortality Improvement Scale were used. For 2018, the RP-2014 Mortality Table and the MP-2018 Mortality Improvement Scale were used. 2020 2019 2018 Weighted average discount rate 2.55 % 3.30 % 4.30 % Rate of increase in compensation levels (a) (a) (a) (a) 6.0% graded down to 3.25% over the first seven years of service. 54 Table of Contents The accumulated benefit obligation was $121,095,000 and $103,736,000 as of December 31, 2020 and 2019, respectively. The Company did not make a contribution during 2020, while in 2019 a contribution of $6,900,000 was made to the Plan. The Company has not determined if it will make a contribution to the Plan in 2021. The following pension benefit payments, which reflect expected future service, as appropriate, are expected to be paid by the Plan: Amount 2021 $ 3,357,000 2022 3,735,000 2023 4,118,000 2024 4,340,000 2025 4,534,000 2026-2030 25,820,000 The Plan’s pension cost included the following components: For the Year Ended December 31, (In thousands) 2020 2019 2018 Service cost – benefits earned during the year $ 4,329 $ 3,555 $ 4,017 Interest cost on projected benefit obligations 3,908 4,103 3,703 Expected return on plan assets (6,049 ) (4,753 ) (5,202 ) Net amortization and deferral 1,946 1,559 1,522 Net periodic pension cost $ 4,134 $ 4,464 $ 4,040 The following represent the major assumptions used to determine the net pension cost of the Plan: 2020 2019 2018 Weighted average discount rate 3.30 % 4.30 % 3.75 % Rate of increase in compensation levels (a ) (a ) (a ) Expected long-term rate of return on assets 6.50 % 6.50 % 6.50 % (a) 6.0% graded down to 3.25% over the first seven years of service For 2020, the Pri-2012 Mortality Table and the MP-2019 Mortality Improvement Table were used. For 2019, the RP-2014 Mortality Table and the MP-2018 Mortality Improvement Table were used. For 2018, the RP-2014 Mortality Table and the MP-2017 Mortality Improvement Table were used. The investment objective for the Plan is to maximize total return with a tolerance for average risk. Asset allocation is a balance between fixed income and equity investments, with a target allocation of approximately 51% fixed income, 19% U.S. equity and 30% non-U.S. equity. Due to volatility in the market, this target allocation is not always desirable and asset allocations can fluctuate between acceptable ranges. The fixed income component is invested in pooled investment grade securities. The equity components are invested in pooled large cap, small/mid cap and non-U.S. stocks. The expected one-year nominal returns and annual standard deviations are shown by asset class below: Asset Class % of Total Portfolio One-Year Nominal Return Annual Standard Deviation Core Fixed Income 51 % 3.04 % 3.85 % Large Cap U.S. Equities 14 % 6.45 % 16.00 % Small Cap U.S. Equities 5 % 7.45 % 20.15 % International (Developed) 25 % 7.95 % 17.83 % International (Emerging) 5 % 10.14 % 25.40 % Applying appropriate correlation factors between each of the asset classes the long-term rate of return on assets is estimated to be 6.50%. 55 Table of Contents A summary of the fair value measurements by type of asset is as follows: Fair Value Measurements as of December 31, 2020 2019 (In thousands) Total Quoted Prices in Active Markets for Identical Assets (Level 1) Observable Inputs (Level 2) Total Quoted Prices in Active Markets for Identical Assets (Level 1) Observable Inputs (Level 2) Cash $ 484 $ 484 $ — $ 462 $ 462 $ — Equity securities U.S. Small/Mid Cap Growth 5,530 — 5,530 4,491 — 4,491 Non-U.

The SERP is a noncontributory plan in which the Company’s subsidiaries make accruals designed to fund normal service costs on a current basis using the same method and criteria as the Plan. A summary of the activity in the SERP’s projected benefit obligation and amounts recognized in the Company’s consolidated balance sheets is as follows: December 31, (In thousands) 2020 2019 Benefit obligation: Balance, January 1 $ 11,712 $ 10,097 Service cost 121 97 Interest cost 347 408 Benefits paid (291 ) (262 ) Actuarial loss 1,523 1,372 Balance, December 31 $ 13,412 $ 11,712 The following represent the major assumptions used to determine the projected benefit obligation of the SERP.

The accumulated benefit obligation was $12,492,000 and $10,485,000 as of December 31, 2020 and 2019, respectively. Since this is an unfunded plan, there are no plan assets. Benefits paid were $291,000 in 2020, $262,000 in 2019, and $260,000 in 2018. Expected future benefits payable by the Company over the next ten years are as follows: Amount 2021 $ 343,000 2022 764,000 2023 851,000 2024 849,000 2025 846,000 2026-2030 4,150,000 56 Table of Contents The SERP’s pension cost included the following components: For the Year Ended December 31, (In thousands) 2020 2019 2018 Service cost – benefits earned during the year $ 121 $ 97 $ 92 Interest cost on projected benefit obligations 347 408 348 Net amortization and deferral 112 276 581 Net periodic pension cost $ 580 $ 781 $ 1,021 The pretax amounts in accumulated other comprehensive loss as of December 31 were as follows: The Plan SERP (In thousands) 2020 2019 2020 2019 Prior service cost $ — $ — $ — $ — Net actuarial loss 15,429 29,387 4,135 2,724 Total $ 15,429 $ 29,387 $ 4,135 $ 2,724 The estimated pretax prior service cost and net actuarial loss in accumulated other comprehensive loss at December 31, 2020 expected to be recognized as components of net periodic benefit cost in 2021 for the Plan are $0 and $360,000, respectively. The estimated pretax prior service cost and net actuarial loss in accumulated other comprehensive loss at December 31, 2020 expected to be recognized as components of net periodic benefit cost in 2021 for the SERP are $0 and $203,000, respectively. The Company also maintains a noncontributory profit sharing program, which covers most of its employees. Employer contributions are calculated based upon formulas which relate to current operating results and other factors. Profit sharing expense recognized in personnel expense in the consolidated statements of income in 2020, 2019, and 2018 was $5,665,000, $6,841,000, and $6,810,000, respectively.

Stock-based Compensation	Note 11 Stock-based Compensation The Amended and Restated Omnibus Stock and Performance Compensation Plan (the “Omnibus Plan”) provides incentive opportunities for key employees and non-employee directors and to align the personal financial interests of such individuals with those of the Company’s shareholders. The Omnibus Plan permits the issuance of up to 1,500,000 shares of the Company’s common stock in the form of stock options, SARs, restricted stock, restricted stock units and performance awards. Restricted Stock Restricted shares granted to Company employees are amortized to expense over the three-year cliff vesting period. Restricted shares granted to members of the Board of Directors are amortized to expense over a one-year service period, with the exception of those shares granted in lieu of cash payments for retainer fees which are expensed in the period earned. Changes in restricted shares outstanding for the year ended December 31, 2020 were as follows: Shares Weighted Average Grant Date Fair Value Balance at December 31, 2019 123,272 $47.24 Granted 38,226 47.07 Vested (20,369 ) 49.32 Forfeited (4,962 ) 50.08 Balance at December 31, 2020 136,167 $46.78 During 2019 and 2018, 36,812 and 35,000 shares, respectively, were granted with weighted average per share market values at date of grant of $49.30 in 2019 and $49.79 in 2018.

A valuation allowance would be provided on deferred tax assets when it is more likely than not that some portion of the assets will not be realized. The Company has not established a valuation allowance at December 31, 2020 or 2019, due to management’s belief that it is more likely than not that the DTA is realizable. 59 Table of Contents The reconciliation of the beginning unrecognized tax benefits balance to the ending balance is presented in the following table: (In thousands) 2020 2019 2018 Balance at January 1 $ 1,299 $ 1,403 $ 1,632 Changes in unrecognized tax benefits as a result of tax positions taken during a prior year 62 56 (135 ) Changes in unrecognized tax benefits as a result of tax position taken during the current year 233 171 192 Reductions to unrecognized tax benefits as a result of a lapse of the applicable statute of limitations (315 ) (331 ) (286 ) Decreases in unrecognized tax benefits as a result of settlements with taxing authorities (48 ) — — Balance at December 31 $ 1,231 $ 1,299 $ 1,403 At December 31, 2020, 2019 and 2018, the balances of the Company’s unrecognized tax benefits which would, if recognized, affect the Company’s effective tax rate were $1,096,000, $1,184,000 and $1,272,000, respectively. These amounts are net of the offsetting benefits from other taxing jurisdictions. As of December 31, 2020, 2019 and 2018, the Company had $114,000, $151,000 and $136,000, respectively, in accrued interest related to unrecognized tax benefits. The Company believes it is reasonably possible that the total amount of unrecognized tax benefits will decrease by approximately $230,000 over the next 12 months. The reduction primarily relates to the anticipated lapse in the statute of limitations. The unrecognized tax benefits relate primarily to apportionment of taxable income among various state tax jurisdictions. The Company is subject to income tax in the U.S. federal jurisdiction, numerous state jurisdictions, and a foreign jurisdiction. The Company’s federal income tax returns for tax years 2018 and 2019 remain subject to examination by the Internal Revenue Service. In addition, the Company is subject to state tax examinations for the tax years 2016 through 2019.

The Company’s maximum potential exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit, commercial letters of credit and standby letters of credit is represented by the contractual amounts of those instruments. At December 31, 2020, an allowance for unfunded commitments of $567,000 had been recorded compared to zero at December 31, 2019. See “Financial Statements and Supplementary Data—Note 1” for information related to CECL adoption. 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. Commercial and standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. These off-balance sheet financial instruments generally have fixed expiration dates or other termination clauses and may require payment of a fee. The approximate remaining terms of commercial and standby letters of credit range from less than one to five years. Since these financial instruments may expire without being drawn upon, the total amounts do not necessarily represent future cash requirements. Commitments to extend credit and letters of credit are subject to the same underwriting standards as those financial instruments included on the consolidated balance sheets. The Company evaluates each customer’s credit-worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary upon extension of the credit, is based on management’s credit evaluation of the borrower. Collateral held varies, but is generally accounts receivable, inventory, residential or income-producing commercial property or equipment. In the event of nonperformance, the Company may obtain and liquidate the collateral to recover amounts paid under its guarantees on these financial instruments. The following table shows conditional commitments to extend credit, standby letters of credit and commercial letters: December 31, (In thousands) 2020 2019 Conditional commitments to extend credit $ 192,916 $ 197,799 Standby letters of credit 10,609 13,288 Commercial letters of credit 955 2,755 60 Table of Contents 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 credit worthiness of such counterparties. The Company believes such commitments have been made at terms which are competitive in the markets in which it operates; however, no premium or discount is offered thereon.

Segment Reporting [Abstract]
Industry Segment Information	Note 17 Industry Segment Information The services provided by the Company are classified into two reportable segments: Information Services and Banking Services. Each of these segments provides distinct services that are marketed through different channels. They are managed separately due to their unique service and processing requirements. The Information Services segment provides transportation, energy, telecommunication, and environmental invoice processing and payment services to large corporations. The Banking Services segment provides banking services primarily to privately held businesses and faith-based ministries, including on-line generosity services, as well as supporting the banking needs of the Information Services segment. The Company’s accounting policies for segments are the same as those described in Note 1 of this report. Management evaluates segment performance based on tax-equivalized (as defined in the footnote to the chart on the following table) pre-tax income after allocations for corporate expenses. Transactions between segments are accounted for at what management believes to be fair value. Substantially all revenue originates from, and all long-lived assets are located within the United States, and no revenue from any customer of any segment exceeds 10% of the Company’s consolidated revenue. Funding sources represent average balances and deposits generated by Information Services and Banking Services and there is no allocation methodology used. Segment interest income is a function of the relative share of average funding sources generated by each segment multiplied by the following rates: • Information Services – one or more fixed rates depending upon the specific characteristics of the funding source, and • Banking Services – a variable rate that is based upon the overall performance of the Company’s earning assets. Any difference between total segment interest income and overall total Company interest income is included in Corporate, Eliminations, and Other. 63 Table of Contents Summarized information about the Company’s operations in each industry segment for the years ended December 31, 2020, 2019 and 2018 is as follows: (In thousands) Information Services Banking Services Corporate, Eliminations and Other Total 2020 Fee income from customers $ 96,548 $ 2,607 $ 1,286 $ 100,441 Interest income* 25,067 29,494 (4,985 ) 49,576 Interest expense — 2,362 — 2,362 Intersegment income (expense) — 2,315 (2,315 ) — Depreciation and amortization 5,194 135 — 5,329 Tax-equivalized pre-tax income* 21,902 14,025 (3,697 ) 32,230 Goodwill 12,433 1,829 — 14,262 Other intangible assets, net 735 2,688 — 3,423 Total Assets 967,702 1,242,688 (7,155 ) 2,203,235 Funding Sources 734,999 738,165 — 1,473,164 2019 Fee income from customers $ 108,882 $ 1,660 $ (473 ) $ 110,069 Interest income* 25,616 30,646 (1,568 ) 54,694 Interest expense — 5,193 — 5,193 Intersegment income (expense) — 2,107 (2,107 ) — Depreciation and amortization 4,659 131 — 4,790 Tax-equivalized pre-tax income* 28,542 13,048 (2,040 ) 39,550 Goodwill 12,433 1,829 — 14,262 Other intangible assets, net 1,142 3,139 — 4,281 Total Assets 844,483 915,341 4,419 1,764,243 Funding Sources 676,068 592,905 — 1,268,973 2018 Fee income from customers $ 102,839 $ 1,307 $ (70 ) $ 104,076 Interest income* 25,074 27,770 (2,496 ) 50,348 Interest expense — 3,736 — 3,736 Intersegment income (expense) — 1,880 (1,880 ) — Depreciation and amortization 4,254 142 — 4,396 Tax-equivalized pre-tax income* 27,763 13,571 (2,566 ) 38,768 Goodwill 12,433 136 — 12,569 Other intangible assets, net 1,554 — — 1,554 Total Assets 826,201 886,291 (17,316 ) 1,695,176 Funding Sources 642,733 572,653 — 1,215,386 * Presented on a tax-equivalent basis assuming a tax rate of 21% for 2020, 2019, and 2018.

Investment in Debt Securities	Investment in Debt Securities Financial Instruments – Credit Losses For available for sale debt securities in an unrealized loss position, the entire loss in fair value is required to be recognized in current earnings if the Company intends to sell the securities or believes it likely that it will be required to sell the security before the anticipated recovery. If neither condition is met, and the Company does not expect to recover the amortized cost basis, the Company determines whether the decline in fair value resulted from credit losses or other factors. If the assessment indicates that a credit loss exists, the present value of cash flows expected to be collected is 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 has occurred, and an allowance for credit losses is recorded. The allowance for credit losses is limited by the amount that the fair value is less than the amortized cost basis. Any impairment not recorded through the provision for credit losses would be recognized in other comprehensive income. Changes in the allowance for credit losses would be recorded as a provision for credit losses on the consolidated statements of income. Losses would be charged against the allowance for credit losses on securities when management believes the uncollectibility of an available for sale security is confirmed or when either of the conditions regarding intent or requirement to sell is met. Prior to the adoption of ASU 2016 -13 as of January 1, 2020, the Company evaluated a decline in the fair value of any available-for-sale security below cost to determine whether the decline was deemed other than temporary and, if so, would result in a charge to earnings and the establishment of a new cost basis for the security. To determine whether impairment was other than temporary, the Company considered guidance provided in the FASB ASC Topic 320, Investments – Debt and Equity Securities. When determining whether a debt security was other-than-temporarily impaired, the Company assessed whether it had the intent to sell the security and whether it was more likely than not that the Company would be required to sell prior to recovery of the amortized cost basis. Evidence considered in this assessment included the reasons for impairment, the severity and duration of the impairment, changes in value subsequent to year-end and forecasted performance of the investee. Premiums and discounts are amortized or accreted to interest income over the estimated lives of the securities using the level-yield method. Interest income is recognized when earned. Gains and losses are calculated using the specific identification method.
Loans	Loans 40 Table of Contents both principal and interest and/or the borrower demonstrates the ability to pay and remain current. Loan origination and commitment fees on originated loans, net of certain direct loan origination costs, are deferred and amortized to interest income using the level-yield method over the estimated lives of the related loans.
Allowance for Credit Losses	Allowance for Credit Losses Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments The ACL is a valuation account that is deducted from the amortized cost basis to present the net amount expected to be collected on the loans. Loans are charged off against the ACL when management believes the uncollectibility of a loan balance is confirmed. Expected recoveries for amounts previously charged off and expected to be charged off do not exceed the aggregate of amounts previously charged off and expected to be charged off. Management estimated the allowance balance using relevant available information from internal and external sources, relating to past events, current conditions and reasonable and supportable forecasts based on economic factors, such as GDP. Historical credit loss experience, of both the Company and similar peer banks, provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made for lending management experience, asset quality trends, borrower’s ability to pay, collateral, and other environmental factors. The ACL is measured on a collective pool basis when similar risk characteristics exist. Management believes the ACL is adequate to absorb expected losses in the loan portfolio. Loans The ACL is measured on a collective pool basis when similar risk characteristics exist. The Company has identified the following portfolio segments: Commercial & Industrial (“C&I”) Commercial Real Estate (“CRE”) Faith-based CRE Construction and Land Development The ACL is calculated as the difference between the amortized cost basis and the projections from the weighted-average remaining maturity ("WARM") model that the Company developed. The WARM model utilizes an attrition analysis, including events such as payoffs, matured loans, and renewals in the borrowers’ control, to anticipate the length of time it would take for each portfolio segment to runoff. Management incorporates a one year GDP forecast and an immediate reversion to peer historical loss rates to determine the annual charge off rates over the estimated life of the loans. After the reasonable and supportable forecast period, the model reverts to long-run historical average loss rates of its peers. However, for the faith-based CRE ACL, beyond the reasonable and supportable forecast period, loss rates are reverted immediately to the Company’s long-run historical averages, as this represents a unique loan segment to the peer portfolios. The economic forecast is based on management’s assessment of the length and pattern of the current economic cycle. The resulting annual charge off rate determined for each year in the WARM model is applied to the loan balances estimated in the attrition analysis. Management accounts for the inherent uncertainty of the underlying economic forecast by reviewing forecast scenarios. Additionally, the ACL calculation includes subjective adjustments for qualitative risk factors that are likely to cause estimated 41 Table of Contents credit losses to differ from historical experience. These qualitative adjustments may increase or reduce reserve levels and include adjustments for lending management experience and risk tolerance, loan review and audit results, asset quality and portfolio trends, loan portfolio growth and loan concentrations. The Company has elected to exclude accrued interest receivable ("AIR") from the allowance for credit losses calculation. When a loan is placed on non-accrual, any recorded AIR is reversed against interest income. The determination and application of the ACL accounting policy involves judgments, estimates, and uncertainties that are subject to change. Changes in these assumptions, estimates or the conditions surrounding them may have a material impact on the Company’s financial condition, liquidity or results of operations. Various regulatory agencies, as an integral part of the examination process, periodically review the ACL. Such agencies may require the Company to recognize additions to the ACL or reserve increases to adversely graded classified loans based on information available to them at the time of their examinations. The ACL is decreased by net charge-offs and is increased by provisions for credit losses that are charged to the consolidated statements of operations. Charge-offs, if any, are typically measured for each loan based on a thorough analysis of the most probable source of repayment, such as the present value of the loan’s expected future cash flows, the loan’s estimated fair value, or the estimated fair value of the underlying collateral less costs of disposition for collateral-dependent loans. When it is determined that specific loans, or portions thereof, are uncollectible, these amounts are charged off against the ACL. Unfunded loan commitments In addition to the ACL for funded loans, the Company maintains reserves to cover the risk of loss associated with off-balance sheet unfunded loan commitments. The allowance for off-balance sheet credit losses is maintained within other liabilities in the statements of financial condition. Under the CECL framework, adjustments to this liability are recorded as provision for credit losses in the consolidated statements of operations. Unfunded loan commitment balances are evaluated by loan segment. In order to establish the required level of reserve, the Company applies average historical utilization rates and ACL loan model loss rates for each loan segment to the outstanding unfunded commitment balances. Investment securities Management evaluates all investments in an unrealized loss position on a quarterly basis, and more frequently when economic or market conditions warrant such evaluation. If the Company has the intent to sell the security or it is more likely than not that the Company will be required to sell the security, the security is written down to fair value and the entire loss is recorded in earnings. If either of the above criteria is not met, the Company will evaluate whether the decline in fair value is the result of credit losses or other factors. In making the assessment, the Company may consider various factors including the extent to which fair value is less than amortized cost, performance on any underlying collateral, downgrades in the ratings of the security by a rating agency, the failure of the issuer to make scheduled interest or principal payments and adverse conditions specifically related to the security. If the assessment indicates that a credit loss exists, the present value of cash flows expected to be collected are compared to the amortized cost basis of the security and any excess is recorded as an allowance for credit loss. For U.S. agency-backed securities where the risk of nonpayment of the amortized cost basis is zero, the Company will not measure expected credit losses on these securities. When the loss is not considered a result of credit loss, the cost basis of the security is written down to fair value, with the loss charge recognized in AOCI. Credit losses are not estimated for AIR from investment securities as interest deemed uncollectible is written off through interest income.
Allowance for Loan Losses	Allowance for Loan Losses Estimated credit losses inherent in the remainder of the portfolio were estimated in accordance with FASB ASC 450, Contingencies. These loans were segmented into groups based on similar risk characteristics. Historical loss rates for each risk group, which were updated quarterly, were generally quantified using all recorded loan charge-offs and recoveries over a prescribed look-back period. These historical loss rates for each risk group were used as the starting point to determine the level of the allowance. The Company’s methodology incorporated an estimated loss emergence period for each risk group. The loss emergence period was the period of time from when a borrower experienced a loss event and when the actual loss was recognized in the financial statements, generally at the time of initial charge-off of the loan balance. The Company’s methodology also included qualitative risk factors that allowed management to adjust its estimates of losses based on the most recent information available and to address other limitations in the quantitative component that was based on historical loss rates. Such risk factors were generally reviewed and updated quarterly, as appropriate, and were adjusted to reflect changes in national and local economic conditions and developments, the volume and severity of delinquent and internally classified loans, loan concentrations, assessment of trends in collateral values, assessment of changes in borrowers’ financial stability, and changes in lending policies and procedures, including underwriting standards and collections, charge-off and recovery practices. 42 Table of Contents Management believed the ALLL was adequate to absorb probable losses in the loan portfolio.

Income Taxes	The Company recognizes and measures income tax benefits using a two-step model: 1) a tax position must be more likely than not to be sustained based solely on its technical merits in order to be recognized; and 2) the benefit must be measured as the largest dollar amount of that position that is more likely than not to be sustained upon settlement. The difference between the benefit recognized for a tax position in this model and the tax benefit claimed on a tax return is treated as an unrecognized tax benefit. The Company recognizes income tax related interest and penalties in income tax expense.

Impact of New and Not Yet Adopted Accounting Pronouncements	Impact of New and Not Yet Adopted Accounting Pronouncements In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments The ASU required measurement and recognition of expected credit losses for financial instruments held at amortized cost, which include allowances for credit losses expected over the life of the portfolio, rather than incurred losses, which include allowances for current known and inherent losses within the portfolio. Under this standard, the Company is required to hold an allowance equal to the expected life-of-loan losses on the loan portfolio. It also applies to off-balance sheet credit exposures such as loan commitments, standby letters of credit and other similar instruments. In addition, ASU 2016-13 made changes to the accounting for available-for-sale debt securities. The Company adopted ASU 2016-13 using a modified retrospective approach. Results for annual reporting periods beginning after January 1, 2020 are presented under ASU 2016-13 while prior period amounts continue to be reported in accordance with 44 Table of Contents previously applicable GAAP. Upon adoption, the Company recognized increases of $723,000 in the allowance for credit losses and $402,000 in the reserve for unfunded commitments, with a corresponding reduction to retained earnings, net of tax, of $856,000. No credit loss allowance was required upon adoption for the investment securities portfolio. Consistent with the provisions of the CARES Act, results for quarterly reporting periods beginning after December 31, 2020 in the Company’s Form 10-Q will be presented under ASU 2016-13 while prior quarterly period amounts continue to be reported in accordance with previously applicable GAAP. The following table illustrates the impact of the adoption of ASU 2016-13: (In thousands) December 31, 2019 Impact of ASU 2016-13 Adoption As Reported Under ASU 2016-13 Assets: Allowance for loan/credit losses on loans $ 10,556 $ 723 $ 11,279 Deferred tax asset 2,298 269 2,567 Liabilities: Reserve for unfunded commitments — 402 402 Shareholders’ equity: Retained earnings 90,341 (856 ) 89,485
Risks and Uncertainties	Risks and Uncertainties On March 11, 2020, the WHO declared the outbreak of COVID-19 as a global pandemic, which continues to spread throughout the United States and around the world. The declaration of a global pandemic indicates that almost all public commerce and related business activities must be, to varying degrees, curtailed with the goal of decreasing the rate of new infections. This response to the COVID-19 pandemic has resulted in an unprecedented slow-down in economic activity and a related increase in unemployment. In late fiscal 2020, vaccines for combatting COVID-19 were approved by health agencies and began to be administered. However, initial quantities of vaccines are limited and vaccine distributions, controlled by local authorities, are being allocated, generally first to front-line health care workers and other essential workers and next to those members of individual populations believed most susceptible to severe effects from COVID-19. The timeline of full administration of the COVID-19 vaccines is uncertain and fluctuating, but is widely thought to be unlikely to occur in most jurisdictions until mid to late 2021. The impact of COVID-19, including the impact of restrictions imposed to combat its spread, could result in additional and prolonged business closures, work restrictions and activity restrictions. The Company has evaluated subsequent events after the consolidated balance sheet date of December 31, 2020 and the breadth of the impact of the global presence of COVID-19 on the Company’s business is currently unknown. The Company is closely monitoring developments related to COVID-19 checking regularly for updated information and recommendations from the WHO and the CDC, from national, state, and local governments, and evaluating courses of action being taken by peers. The duration and severity of the effect of COVID-19 on economic, market and business conditions and the timeline and shape of recovery from the pandemic remain uncertain. At this time, the Company remains subject to heightened business, operational, market, credit and other risks related to the COVID-19 pandemic, including, but not limited to, those discussed below, which may have an adverse effect on business, financial condition and results of operations. Financial position and results of operations - The global health crisis caused by COVID-19 has and will continue to negatively impact business activity throughout the world. The COVID-19 outbreak and associated counter-acting measures implemented by governments around the world, as well as increased business uncertainty, have had, and continue to have, an adverse impact on the Company’s financial results and are discussed in more detail below. Although in various locations certain activity restrictions have been relaxed with some success, many states and localities are experiencing significant increases in the number of COVID-19 cases, prompting a reinstatement of prior activity restrictions in some locations and the need for additional aid and other forms of relief for affected individuals, businesses and other entities. When and if COVID-19 is demonstrably contained, the Company anticipates a rebound in economic activity; however, any such rebound is contingent upon the rate and effectiveness of the containment efforts deployed by federal, state, and local governments. In light of the evolving health, social, economic and business environment, governmental regulations or mandates, and business disruptions that have occurred and could continue to occur, the aggregate impact that COVID-19 could have on the Company’s financial condition and operating results remains highly uncertain. In response to COVID-19, the Federal Reserve has taken action to lower the Federal Funds rate, which has adversely affected interest income and therefore, the Company’s results of operations and financial condition. The Federal Reserve has continued 45 Table of Contents its commitment to this approach, indicating that the target Federal Funds rate would remain at current levels until the economy is in a more stable employment and price-stability position. To the extent the business disruption continues for an extended period, additional cost control actions will be considered. Future asset impairment charges, increases in allowance for credit losses, or restructuring charges could be more likely and will be dependent on the severity and duration of this crisis and its effect on the Company’s borrowers. For payment processing services, business closures, including constrictions in the manufacturing sector, have led to a decrease in the number of transactions and dollars processed due to the decline in customers’ business activity. In addition, the dampened demand for oil and resulting plummet in oil prices has had, and can continue to have, a negative effect on both the number of freight transactions processed and the dollar amount of invoices processed. Other financial impact could occur though such potential impact is unknown at this time. Capital and liquidity - While the Company believes that it has sufficient capital to withstand an extended economic recession brought about by COVID-19, its reported and regulatory capital ratios could be adversely impacted by future financial losses. The Company maintains access to multiple sources of liquidity. If funding costs are elevated for an extended period of time, it could have an adverse effect on the Company’s net interest margin. If an extended recession caused large numbers of the Bank’s customers to draw down deposits, the Company might become more reliant on more expensive sources of funding. Asset valuation - Currently, the Company does not expect COVID-19 to affect its ability to fairly value the assets on its balance sheet; however, this could change in future periods. While certain valuation assumptions and judgments will change to account for pandemic-related circumstances such as widening credit spreads, the Company does not anticipate significant changes in methodology used to determine the fair value of assets measured in accordance with GAAP. The economic slowdown as a result of COVID-19 could cause a further and sustained decline in the Company’s stock price or the occurrence of what management would deem to be a triggering event that could, under certain circumstances, necessitate a goodwill or intangible asset impairment test and result in an impairment charge being recorded for that period. In the event that the Company concludes that all or a portion of its goodwill is impaired, a non-cash charge for the amount of such impairment would be recorded to earnings. Such a charge would have no impact on tangible capital or regulatory capital. Processes, controls and business continuity - In accord with its federally mandated Pandemic Plan and Business Continuity Plan, Cass has deployed its remote workforce program. Most Cass employees around the globe are now working and conducting business remotely. Employees necessary to oversee certain business coordination activities or to conduct essential physical activities such as mail handling and scanning operations, remain in offices. In addition, employees are now being permitted to return to the offices on a voluntary basis. Employees are required to report any exposure or diagnosis and must adhere to the defined safety protocol to enter the offices. In the past several years, Cass has invested in sophisticated technology initiatives that enable employees to operate remotely with full system(s) access along with unified and transparent voice and electronic communications capabilities, ensuring seamless service delivery. The Company cannot predict when or how it will fully lift the actions put in place as part of the Business Continuity Plan, including work from home requirements and travel restrictions. Cass does not believe the work from home protocol has materially adversely impacted internal controls, financial reporting systems, or operations.

The Company’s investment securities available-for-sale at December 31, 2020 and 2019 are measured at fair value using Level 2 valuations. The market evaluation utilizes several sources which include “observable inputs” rather than “significant unobservable inputs” and therefore falls into the Level 2 category.
