Additionally, various regulatory agencies, as an integral part of their examination process, periodically review the Company’s ALLL. Such agencies may require the Company to increase the ALLL based on their judgments and interpretations about information available to them at the time of their examinations. 37 Table of Contents 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 Foreclosed Assets Treasury Stock Comprehensive Income Loans Impairment of Loans Information Services Revenue Income Taxes 38 Table of Contents 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.

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, 2019 and 2018, 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 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 December 31, 2019. The Bank is also subject to the regulatory framework for prompt corrective action. As of December 31, 2019, 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, 2019, unappropriated retained earnings of $52,786,000 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, 2019 and 2018. The Company’s and the Bank’s actual and required capital amounts and ratios are as follows: Actual Capital Requirements Requirement to be Well-Capitalized (In thousands) Amount Ratio Amount Ratio Amount Ratio At December 31, 2019 Total capital (to risk-weighted assets) Cass Information Systems, Inc. $ 249,954 19.70 % $ 101,530 8.00 % $ N/A N/A % Cass Commercial Bank 154,011 19.32 63,778 8.00 79,722 10.00 Common Equity Tier I Capital (to risk-weighted assets) Cass Information Systems, Inc. 239,398 18.86 57,110 4.50 N/A N/A Cass Commercial Bank 145,673 18.27 35,875 4.50 51,819 6.50 Tier I capital (to risk-weighted assets) Cass Information Systems, Inc. 239,398 18.86 76,147 6.00 N/A N/A Cass Commercial Bank 145,673 18.27 47,833 6.00 63,778 8.00 Tier I capital (to average assets) Cass Information Systems, Inc. 239,398 13.24 72,329 4.00 N/A N/A Cass Commercial Bank 145,673 16.64 35,012 4.00 43,765 5.00 40 Table of Contents At December 31, 2018 Total capital (to risk-weighted assets) Cass Information Systems, Inc. $ 244,660 21.38 % $ 91,550 8.00 % $ N/A N/A % Cass Commercial Bank 137,894 18.31 60,257 8.00 75,321 10.00 Common Equity Tier I Capital (to risk-weighted assets) Cass Information Systems, Inc. 234,435 20.49 51,497 4.50 N/A N/A Cass Commercial Bank 130,037 17.26 33,895 4.50 48,959 6.50 Tier I capital (to risk-weighted assets) Cass Information Systems, Inc. 234,435 20.49 68,662 6.00 N/A N/A Cass Commercial Bank 130,037 17.26 45,193 6.00 60,257 8.00 Tier I capital (to average assets) Cass Information Systems, Inc. 234,435 13.89 67,500 4.00 N/A N/A Cass Commercial Bank 130,037 15.35 33,884 4.00 42,354 5.00

Investments, Debt and Equity Securities [Abstract]
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, 2019 and 2018 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. The table below presents the balances of securities available-for-sale measured at fair value on a recurring basis. The amortized cost, gross unrealized gains, gross unrealized losses and fair value of debt and equity securities are summarized as follows: December 31, 2019 (In thousands) Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value State and political subdivisions $ 310,720 $ 13,727 $ — $ 324,447 U.S. government agencies 97,380 507 169 97,718 Certificates of deposit 500 — — 500 Total $ 408,600 $ 14,234 $ 169 $ 422,665 December 31, 2018 (In thousands) Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value State and political subdivisions $ 332,732 $ 3,791 $ 1,806 $ 334,717 U.S. government agencies 106,153 86 1,417 104,822 Certificates of deposit 1,995 — — 1,995 Total $ 440,880 $ 3,877 $ 3,223 $ 441,534 The fair values of securities with unrealized losses are as follows: December 31, 2019 Less than 12 months 12 months or more Total (In thousands) Estimated Fair Value Unrealized Losses Estimated Fair Value Unrealized Losses Estimated Fair value Unrealized Losses State and political subdivisions $ — $ — $ — $ ─ $ — $ — U.S. government agencies 3,801 12 17,593 157 21,394 169 Certificates of deposit — — — ─ — — Total $ 3,801 $ 12 $ 17,593 $ 157 $ 21,394 $ 169 December 31, 2018 Less than 12 months 12 months or more Total (In thousands) Estimated Fair Value Unrealized Losses Estimated Fair Value Unrealized Losses Estimated Fair value Unrealized Losses State and political subdivisions $ 91,248 $ 556 $ 60,546 $ 1,250 $ 151,794 $ 1,806 U.S. government agencies 30,409 130 38,005 1,287 68,414 1,417 Certificates of deposit — — — — — — Total $ 121,657 $ 686 $ 98,551 $ 2,537 $ 220,208 $ 3,223 41 Table of Contents There were 9 securities, or 3% of the total (7 greater than 12 months), in an unrealized loss position as of December 31, 2019 compared to 136 securities, or 43% (61 greater than 12 months), in an unrealized loss position as of December 31, 2018. All unrealized losses are reviewed to determine whether the losses are other than temporary. Management believes that all unrealized losses are temporary since they are market driven, the Company does not have the intent to sell the security, and it is more likely than not that the Company will not be required to sell prior to recovery of the amortized basis.

(2) Loans subject to special monitoring possess some credit deficiency or potential weakness which requires a high level of management attention. Impaired loans consist primarily of nonaccrual loans, loans greater than 90 days past due and still accruing interest and troubled debt restructurings, both performing and non-performing. Troubled debt restructuring involves the granting of a concession to a borrower experiencing financial difficulty resulting in the modification of terms of the loan, such as changes in payment schedule or interest rate. There was no ALLL related to impaired loans at both December 31, 2019 and 2018. There were no non-accrual loans at December 31, 2019 and 2018. There were no loans delinquent 90 days or more and still accruing interest at both December 31, 2019 and 2018. At December 31, 2019 and 2018, there were no loans classified as troubled debt restructuring. The average balances of impaired loans during 2019, 2018 and 2017 were $0, $0, and $166,000, respectively. Income that would have been recognized on non-accrual loans under the original terms of the contract was $0, $0, and $24,000 for 2019, 2018, and 2017, respectively. Income that was recognized on nonaccrual loans was $0, $0, and $17,000, for 2019, 2018, and 2017 respectively. There were no foreclosed assets as of December 31, 2019 or 2018. The Company does not record loans at fair value on a recurring basis. Once a loan is identified as impaired, management measures impairment in accordance with FASB ASC 310. At December 31, 2019 and 2018, there were no impaired loans. The fair value of the collateral is based upon an observable market price or current appraised value and therefore, the Company classifies these assets as nonrecurring Level 3. A summary of the activity in the allowance for loan losses for the period ended December 31, 2019 is as follows: (In thousands) December 31, 2018 Charge- Offs Recoveries Provision December 31, 2019 Commercial and industrial $ 4,179 $ — $ 81 $ 593 $ 4,853 Real estate Commercial: Mortgage 1,417 — — 105 1,522 Construction 89 — — 101 190 Faith-based: Mortgage 3,961 — — (135 ) 3,826 Construction 155 — — (35 ) 120 Other 424 — — (379 ) 45 Total $ 10,225 $ — $ 81 $ 250 $ 10,556 44 Table of Contents A summary of the activity in the allowance for loan losses for the period ended December 31, 2018 is as follows: (In thousands) December 31, 2017 Charge- Offs Recoveries Provision December 31, 2018 Commercial and industrial $ 3,652 $ — $ 20 $ 507 $ 4,179 Real estate Commercial: Mortgage 1,394 — — 23 1,417 Construction 70 — — 19 89 Faith-based: Mortgage 3,962 — — (1 ) 3,961 Construction 196 — — (41 ) 155 Industrial Revenue Bond 52 — — (52 ) — Other 879 — — (455 ) 424 Total $ 10,205 $ — $ 20 $ — $ 10,225 As of December 31, 2019 and 2018, there were loans totaling $167,429 and $278,153, respectively, to affiliates of executive officers or directors.

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.

Employee Benefit Plans	Note 10 Employee Benefit Plans Defined Benefit Plan The Company has a noncontributory defined-benefit pension plan (the “Plan”), which covers most of its employees. Effective December 31, 2016, the Plan was closed to all new participants. 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: 47 Table of Contents (In thousands) 2019 2018 Projected benefit obligation: Balance, January 1 $ 96,401 $ 98,790 Service cost 3,554 4,017 Interest cost 4,103 3,703 Actuarial loss (gain) 18,334 (7,768 ) Benefits paid (2,565 ) (2,341 ) Balance, December 31 $ 119,827 $ 96,401 Plan assets: Fair value, January 1 $ 74,580 $ 81,427 Actual return 15,719 (4,506 ) Employer contribution 6,900 — Benefits paid (2,565 ) (2,341 ) Fair value, December 31 $ 94,634 $ 74,580 Funded status: Accrued pension liability $ (25,192 ) $ (21,821 ) The following represent the major assumptions used to determine the projected benefit obligation of the Plan. For 2019 and 2018, the Plan’s expected benefit cash flows were discounted using the FTSE Above Median Double-A Curve while in 2017, the Plan’s expected benefit cash flows were discounted using the Citibank Above Median Curve. 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. For 2017, the RP-2014 Mortality Table and MP-2017 Mortality Improvement Scale were used. 2019 2018 2017 Weighted average discount rate 3.30 % 4.30 % 3.75 % Rate of increase in compensation levels (a) (a) (a) (a) 6.0% graded down to 3.25% over the first seven years of service. The accumulated benefit obligation was $103,736,000 and $83,724,000 as of December 31, 2019 and 2018, respectively. During 2019, the Company made a contribution of $6,900,000 to the Plan. The Company has not determined if it will make a contribution to the Plan in 2020. The following pension benefit payments, which reflect expected future service, as appropriate, are expected to be paid by the Plan: Amount 2020 $ 3,098,000 2021 3,367,000 2022 3,766,000 2023 4,196,000 2024 4,488,000 2025-2029 27,343,000 The Plan’s pension cost included the following components: For the Year Ended December 31, (In thousands) 2019 2018 2017 Service cost – benefits earned during the year $ 3,555 $ 4,017 $ 3,733 Interest cost on projected benefit obligations 4,103 3,703 3,621 Expected return on plan assets (4,753 ) (5,202 ) (4,681 ) Net amortization and deferral 1,559 1,522 1,382 Net periodic pension cost $ 4,464 $ 4,040 $ 4,055 The following represent the major assumptions used to determine the net pension cost of the Plan: 2019 2018 2017 Weighted average discount rate 4.30 % 3.75 % 4.25 % 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 48 Table of Contents 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. For 2017, the RP-2014 Mortality Table and the MP-2016 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 % 3.78 % 3.90 % Large Cap U.S. Equities 14 % 6.55 % 15.30 % Small Cap U.S. Equities 5 % 7.58 % 19.00 % International (Developed) 25 % 7.86 % 17.22 % International (Emerging) 5 % 10.24 % 25.05 % Applying appropriate correlation factors between each of the asset classes the long-term rate of return on assets is estimated to be 6.50%.

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) 2019 2018 Benefit obligation: Balance, January 1 $ 10,097 $ 10,094 Service cost 97 92 Interest cost 408 348 Benefits paid (262 ) (260 ) Actuarial loss (gain) 1,372 (177 ) Balance, December 31 $ 11,712 $ 10,097 49 Table of Contents The following represent the major assumptions used to determine the projected benefit obligation of the SERP. For 2019 and 2018, the SERP’s expected benefit cash flows were discounted using the FTSE Above Median Double-A Curve. For 2017, the Citigroup Above Median Curve was used. 2019 2018 2017 Weighted average discount rate 3.00 % 4.10 % 3.50 % Rate of increase in compensation levels (a) (a) (a) (a) 6.00% graded down to 3.25% over the first seven years of service. The accumulated benefit obligation was $10,485,000 and $8,830,000 as of December 31, 2019 and 2018, respectively. Since this is an unfunded plan, there are no plan assets. Benefits paid were $262,000 in 2019, $260,000 in 2018, and $247,000 in 2017. Expected future benefits payable by the Company over the next ten years are as follows: Amount 2020 $ 291,000 2021 344,000 2022 752,000 2023 829,000 2024 826,000 2025-2029 4,055,000 The SERP’s pension cost included the following components: For the Year Ended December 31, (In thousands) 2019 2018 2017 Service cost – benefits earned during the year $ 97 $ 92 $ 143 Interest cost on projected benefit obligations 408 348 360 Net amortization and deferral 276 581 324 Net periodic pension cost $ 781 $ 1,021 $ 827 The pretax amounts in accumulated other comprehensive loss as of December 31 were as follows: The Plan SERP (In thousands) 2019 2018 2019 2018 Prior service cost $ — $ — $ — $ — Net actuarial loss 29,387 23,580 2,724 1,629 Total $ 29,387 $ 23,580 $ 2,724 $ 1,629 The estimated pretax prior service cost and net actuarial loss in accumulated other comprehensive loss at December 31, 2019 expected to be recognized as components of net periodic benefit cost in 2020 for the Plan are $0 and $1,890,000, respectively. The estimated pretax prior service cost and net actuarial loss in accumulated other comprehensive loss at December 31, 2019 expected to be recognized as components of net periodic benefit cost in 2020 for the SERP are $0 and $112,000, 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 2019, 2018, and 2017 was $6,841,000, $6,810,000, and $5,799,000, respectively. The Company also sponsors a defined contribution 401(k) plan to provide additional retirement benefits to substantially all employees. Contributions under the 401(k) plan for 2019, 2018 and 2017 were $1,378,000, $1,109,000, and $925,000, respectively.

Share-based Payment Arrangement [Abstract]
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. 50 Table of Contents Restricted Stock Restricted shares granted prior to April 16, 2013 are amortized to expense over the three-year vesting period. Beginning on April 16, 2013, restricted shares granted to Company employees are amortized to expense over the three-year annual vesting period whereas 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 payment for retainer fees which are expensed in the period earned. Beginning on February 2, 2017, restricted shares granted to Company employees are amortized to expense over the three-year cliff vesting period. Changes in restricted shares outstanding for the year ended December 31, 2019 were as follows: Shares Weighted Average Grant Date Fair Value Balance at December 31, 2018 99,724 $45.48 Granted 36,812 49.30 Vested (13,264 ) 39.76 Balance at December 31, 2019 123,272 $47.24 During 2018 and 2017, 35,000 and 31,277 shares, respectively, were granted with weighted average per share market values at date of grant of $49.79 in 2018 and $49.55 in 2017. The fair value of such shares are based on the market price on the date of grant. Amortization of the restricted stock bonus awards totaled $1,551,000 for 2019, $1,571,000 for 2018 and $1,743,000 for 2017. As of December 31, 2019, the total unrecognized compensation expense related to non-vested restricted stock awards was $1,438,000 and the related weighted average period over which it is expected to be recognized is approximately 1.07 years. The total fair value of shares vested during the years ended December 2019, 2018, and 2017 was $527,000, $1,112,000, and $1,389,000, respectively. Performance-Based Restricted Stock In February 2017, the Company granted three-year PBRS awards which are contingent upon the Company’s achievement of pre-established financial goals over the period from January 1, 2017 through December 31, 2019. The PBRS awards cliff vest on the three year anniversary of their grant date at levels ranging from 0% to 150% of the target opportunity based on the actual achievement of financial goals for the three-year performance period. The aggregate target number of PBRS shares granted was 30,388 with an average grant date fair value of $49.33 per share. The 2019 expense related to these grants totaled $583,000 and is based on the grant date fair value of the awards and the Company’s achievement of 118% of the target financial goals. The estimated expense for 2019 and each future period through the vesting date is subject to prospective adjustment based upon changes in the expected achievement of the financial goals. In each of February and July 2018, the Company granted three-year PBRS awards which are contingent upon the Company’s achievement of pre-established financial goals over the period from January 1, 2018 through December 31, 2020. The PBRS awards cliff vest on the three-year anniversary of their grant date at levels ranging from 0% to 150% of the target opportunity based on the actual achievement of financial goals for the three-year performance period. The aggregate target number of PBRS shares granted was 35,602 with an average grant date fair value of $49.04 per share. The 2019 expense related to these grants totaled $674,000 and is based on the grant date fair value of the awards and the Company’s achievement of 117% of the target financial goals. The estimated expense for 2019 and each future period through the vesting date is subject to prospective adjustment based upon changes in the expected achievement of the financial goals. In each of February and June 2019, the Company granted three-year PBRS awards which are contingent upon the Company’s achievement of pre-established financial goals over the period from January 1, 2019 through December 31, 2021. The PBRS awards cliff vest on the three-year anniversary of their grant date at levels ranging from 0% to 150% of the target opportunity based on the actual achievement of financial goals for the three-year performance period. The aggregate target number of PBRS shares granted was 36,801 with an average grant date fair value of $49.06 per share. The 2019 expense related to these grants totaled $593,000 and is based on the grant date fair value of the awards and the Company’s achievement of 108% of the target financial goals. The estimated expense for 2019 and each future period through the vesting date is subject to prospective adjustment based upon changes in the expected achievement of the financial goals. SARs During 2019, there were no SARs granted and no expense recognized. As of December 31, 2019, there was no unrecognized compensation expense related to SARs. 51 Table of Contents Changes in SARs outstanding for the year ended December 31, 2019 were as follows: SARs Weighted Average Exercise Price Balance at December 31, 2018 237,121 $29.86 Exercised (81,829 ) 24.71 Forfeited — — Balance at December 31, 2019 155,292 32.58 Exercisable at December 31, 2019 155,292 $32.58 The total intrinsic value of SARs exercised during 2019 and 2018 was $2,022,000 and $1,110,000, respectively.

When measured as a percent of pre-tax income, the Company’s effective tax rate was 19% in 2019, 17% in 2018, and 28% in 2017. The increase in 2019 tax expense was primarily the result of the decrease in the amount of tax-exempt income from municipal bonds, an increase in state tax expense, and a prior year reduction of tax expense recorded from the final analysis and measurement of the TCJA. 52 Table of Contents The tax effects of temporary differences which give rise to significant portions of the deferred tax assets and deferred tax liabilities are presented below: December 31, (In thousands) 2019 2018 Deferred tax assets: Allowance for loan losses $ 2,452 $ 2,376 ASC 715 pension funding liability 7,642 6,000 Net operating loss carryforward (1) 27 50 Supplemental executive retirement plan accrual 2,087 1,968 Stock compensation 1,987 1,673 Total deferred tax assets $ 14,195 $ 12,067 Deferred tax liabilities: Premises and equipment (2,821 ) (1,937 ) Pension (974 ) (409 ) Intangible assets (1,379 ) (1,212 ) Unrealized gain on investment in securities available-for-sale (3,348 ) (156 ) Other (196 ) (80 ) Total deferred tax liabilities $ (8,718 ) $ (3,794 ) Net deferred tax assets $ 5,477 $ 8,273 (1) As of December 31, 2019, the Company had approximately $128,000 of net operating loss carry forwards as a result of the acquisition of Franklin Bancorp. The utilization of the net operating loss carry forward is subject to Section 382 of the Internal Revenue Code and limits the Company’s use to approximately $122,000 per year during the carry forward period, which expires in 2024 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, 2019 or 2018, due to management’s belief that all criteria for recognition have been met, including the expectation of projected future taxable income sufficient to support the realization of deferred tax assets. The reconciliation of the beginning unrecognized tax benefits balance to the ending balance is presented in the following table: (In thousands) 2019 2018 2017 Balance at January 1 $ 1,403 $ 1,632 $ 1,623 Changes in unrecognized tax benefits as a result of tax positions taken during a prior year 56 (135 ) (15 ) Changes in unrecognized tax benefits as a result of tax position taken during the current year 171 192 263 Reductions to unrecognized tax benefits as a result of a lapse of the applicable statute of limitations (331 ) (286 ) (239 ) Balance at December 31 $ 1,299 $ 1,403 $ 1,632 At December 31, 2019, 2018 and 2017, the balances of the Company’s unrecognized tax benefits which would, if recognized, affect the Company’s effective tax rate were $1,184,000, $1,272,000 and $1,464,000, respectively. These amounts are net of the offsetting benefits from other taxing jurisdictions. As of December 31, 2019, 2018 and 2017, the Company had $151,000, $136,000 and $139,000, 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 $315,000 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 2016 through 2018 remain subject to examination by the Internal Revenue Service. In addition, the Company is subject to state tax examinations for the tax years 2015 through 2018. The Company is currently under audit from the Internal Revenue Service for the 2017 tax year.

Fair Value Disclosures [Abstract]
Disclosures about Fair Value of Financial Instruments	Note 14 Disclosures about Fair Value of Financial Instruments The Company is party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit, commercial letters of credit and standby letters of credit. 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, 2019 and 2018, no amounts have been accrued for any estimated losses for these instruments. 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) 2019 2018 Conditional commitments to extend credit $ 197,799 $ 144,010 Standby letters of credit 13,288 11,368 Commercial letters of credit 2,755 3,486 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.

Revenue from Contracts with Customers	Note 16 Revenue from Contracts with Customers On January 1, 2018, the Company adopted FASB ASC 606 and selected the modified retrospective transition method. The adoption of this new standard did not impact the Company’s results of operations or balance sheet and there was no cumulative effect of initially applying this new revenue standard to the opening balance of retained earnings. Since interest income on loans and securities are both excluded from this topic, a significant portion of the Company’s revenues are not subject to the new guidance. The services that fall within the scope of FASB ASC 606 are presented within fee revenue and other income in the consolidated statements of income and are recognized as revenue as the performance obligation to the customer is satisfied. Services within the scope of FASB ASC 606 include invoice processing and payment fees, bank service fees, and OREO.

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. Certain amounts in the table below for 2018 and 2017 have been reclassified to conform to the 2019 presentation. 56 Table of Contents Summarized information about the Company’s operations in each industry segment for the years ended December 31, 2019, 2018 and 2017, is as follows: (In thousands) Information Services Banking Services Corporate, Eliminations and Other Total 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 2017 Fee income from customers $ 93,484 $ 1,547 $ 481 $ 95,512 Interest income* 23,813 27,376 (3,522 ) 47,667 Interest expense — 2,187 — 2,187 Intersegment income (expense) — 1,362 (1,362 ) — Depreciation and amortization 3,902 149 — 4,051 Tax-equivalized pre-tax income* 28,168 15,460 (3,039 ) 40,589 Goodwill 12,433 136 — 12,569 Other intangible assets, net 1,996 — — 1,996 Total Assets 854,214 830,672 (27,677 ) 1,603,209 Funding Sources 604,493 598,986 — 1,203,479 * Presented on a tax-equivalent basis assuming a tax rate of 21% for 2019 and 2018 and 35% for 2017.

Leases [Abstract]
Leases	Note 18 Leases On January 1, 2019, the Company adopted ASU 2016-02. The Company leases certain premises under operating leases. As of December 31, 2019, the Company had lease liabilities of $6,682,000 and right-of-use assets of $5,848,000. Lease liabilities and right-of-use assets are reflected in other liabilities and other assets, respectively. Included in occupancy expense on the consolidated statements of income for 2019 was operating lease cost of $1,675,000, short-term lease cost of $145,000, and there was no variable lease cost. The Company paid cash of $1,531,000 for operating lease amounts included in the measurement of lease liabilities for the year ended December 31, 2019. No right-of-use assets were obtained in exchange for lease liabilities during the year ended December 31, 2019. For the year ended December 31, 2019, the weighted average remaining lease term for the operating leases was 6.4 years and the weighted average discount rate used in the measurement of operating lease liabilities was 5.5%. Certain of the Company’s leases contain options to renew the lease; however, these renewal options are not included in the calculation of the lease liabilities as they are not reasonably certain to be exercised. There has been no significant change in the Company’s expected future minimum lease payments since December 31, 2018. 57 Table of Contents A maturity analysis of operating lease liabilities and undiscounted cash flows as of December 31, 2019 was as follows: (In thousands) December 31, 2019 Lease payments due Less than 1 year $ 1,748 1-2 years 1,613 2-3 years 1,538 3-4 years 614 4-5 years 392 Over 5 years 1,972 Total undiscounted cash flows 7,877 Discount on cash flows 1,195 Total lease liability $ 6,682 There were no sale and leaseback transactions, leveraged leases, or lease transactions with related parties during the year ended December 31, 2019.

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.

The Company’s investment securities available-for-sale at December 31, 2019 and 2018 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. The table below presents the balances of securities available-for-sale measured at fair value on a recurring basis. The amortized cost, gross unrealized gains, gross unrealized losses and fair value of debt and equity securities are summarized as follows: December 31, 2019 (In thousands) Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value State and political subdivisions $ 310,720 $ 13,727 $ — $ 324,447 U.S. government agencies 97,380 507 169 97,718 Certificates of deposit 500 — — 500 Total $ 408,600 $ 14,234 $ 169 $ 422,665 December 31, 2018 (In thousands) Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value State and political subdivisions $ 332,732 $ 3,791 $ 1,806 $ 334,717 U.S. government agencies 106,153 86 1,417 104,822 Certificates of deposit 1,995 — — 1,995 Total $ 440,880 $ 3,877 $ 3,223 $ 441,534
