Those intangible assets were estimated as $974,000 for the customer list and $100,000 for non-compete agreements. The amounts will be adjusted upon the completion of a valuation. Details of the Company’s intangible assets are as follows: March 31, 2017 December 31, 2016 Gross Carrying Accumulated Gross Carrying Accumulated (In thousands) Amount Amortization Amount Amortization Assets eligible for amortization: Customer lists $ 4,907 $ (2,429 ) $ 3,933 $ (2,342 ) Patent 72 (9 ) 72 (8 ) Non-compete agreements 361 (263 ) 261 (261 ) Software 234 (234 ) 234 (234 ) Other 500 (167 ) 500 (158 ) Unamortized intangible assets: Goodwill 1 11,817 (227 ) 11,817 (227 ) Total intangible assets $ 17,891 $ (3,329 ) $ 16,817 $ (3,230 ) 1 The customer lists are amortized over seven and ten years; the patents over 18 years; the non-compete agreements over five years; software over three years; and other intangible assets over fifteen years. Amortization of intangible assets amounted to $99,000 and $102,000 for the three-month periods ended March 31, 2017 and 2016, respectively. Estimated annual amortization of intangibles is as follows: $456,000 in 2017, and $476,000 in each of 2018, 2019, 2020 and 2021.

Earnings Per Share [Abstract]
Earnings Per Share	Note 3 – Earnings Per Share Basic earnings per share is computed by dividing net income by the weighted-average number of common shares outstanding. 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. There were no anti-dilutive shares in the three months ended March 31, 2017 and 2016. The calculations of basic and diluted earnings per share are as follows: Three Months Ended March 31, (In thousands except share and per share data) 2017 2016 Basic Net income $ 6,307 $ 5,833 Weighted-average common shares outstanding 11,124,250 11,233,558 Basic earnings per share $ .57 $ .52 Diluted Net income $ 6,307 $ 5,833 Weighted-average common shares outstanding 11,124,250 11,233,558 Effect of dilutive restricted stock and stock appreciation rights 166,671 153,299 Weighted-average common shares outstanding assuming dilution 11,290,921 11,386,857 Diluted earnings per share $ .56 $ .51

Segment Reporting [Abstract]
Industry Segment Information	Note 5 – 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, processing and capital 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 churches. The Company’s accounting policies for segments are the same as those described in the summary of significant accounting policies in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016. Management evaluates segment performance based on net income after allocations for corporate expenses and income taxes. 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. Assets represent actual assets owned by Information Services and Banking Services and there is no allocation methodology used. Segment interest from customers is the actual interest earned on the loans owned by Information Services and Banking Services, respectively. Summarized information about the Company’s operations in each industry segment is as follows: Corporate, Information Banking Eliminations (In thousands) Services Services and Other Total Three Months Ended March 31, 2017 Fee revenue and other income: Income from customers $ 23,646 $ 6,644 $ — $ 30,290 Intersegment income (expense) 2,964 361 (3,325 ) — Net income 3,824 2,483 — 6,307 Goodwill 11,454 136 — 11,590 Other intangible assets, net 2,971 — — 2,971 Total assets 747,301 715,753 (16,048 ) 1,447,006 Three Months Ended March 31, 2016 Fee revenue and other income: Income from customers $ 23,558 $ 7,211 $ — $ 30,769 Intersegment income (expense) 3,258 376 (3,634 ) — Net income 2,947 2,886 — 5,833 Goodwill 11,454 136 — 11,590 Other intangible assets, net 2,303 — — 2,303 Total assets 663,487 718,234 (4,703 ) 1,377,018

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. Management measures impairment in accordance with FASB ASC 310, “Allowance for Credit Losses.” At March 31, 2017 and December 31, 2016, impaired loans were evaluated using the expected cash flow method. 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. There were no loans delinquent 90 days or more and still accruing interest at March 31, 2017 and December 31, 2016. There were no loans classified as troubled debt restructuring at March 31, 2017 and December 31, 2016. There were no foreclosed loans recorded as other real estate owned (included in other assets) as of March 31, 2017 and December 31, 2016.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 7 – Commitments and Contingencies In the normal course of business, the Company is party to activities that contain credit, market and operational risks that are not reflected in whole or in part in the Company’s consolidated financial statements. Such activities include traditional off-balance sheet credit-related financial instruments and commitments under operating leases. 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 March 31, 2017 and December 31, 2016, 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 or its subsidiaries 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. At March 31, 2017, the balance of unused loan commitments, standby and commercial letters of credit were $54,977,000, $13,101,000, and $1,800,000, respectively. Since some of the 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 or its subsidiaries may obtain and liquidate the collateral to recover amounts paid under guarantees on these financial instruments. The following table summarizes contractual cash obligations of the Company related to operating lease commitments and time deposits at March 31, 2017: Amount of Commitment Expiration per Period Less than 1-3 3-5 Over 5 (In thousands) Total 1 Year Years Years Years Operating lease commitments $ 6,002 $ 1,544 $ 2,120 $ 1,696 $ 642 Time deposits 55,969 50,098 3,704 2,167 — Total $ 61,971 $ 51,642 $ 5,824 $ 3,863 $ 642 The Company and its subsidiaries are involved in various pending legal actions and proceedings in which claims for damages are asserted. Management, after discussion with legal counsel, believes the ultimate resolution of these legal actions and proceedings will not have a material effect upon the Company’s consolidated financial position or results of operations.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	Note 8 – Stock-Based Compensation The Amended and Restated Omnibus Stock and Performance Compensation Plan (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, stock appreciation rights (“SARs”), restricted stock, restricted stock units and performance awards. The Company may issue shares out of treasury stock for these awards. During the three months ended March 31, 2017, 15,356 restricted shares, 23,038 performance-based restricted shares, and 0 SARs were granted under the Omnibus Plan. Restricted Stock Restricted shares granted prior to April 16, 2013 are amortized to expense over a three-year vesting period. Beginning on April 16, 2013, restricted shares granted to Company employees are amortized to expense over a three-year 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 payments for retainer fees which are expensed in the period earned. As of March 31, 2017, the total unrecognized compensation expense related to non-vested restricted shares was $2,253,000, and the related weighted-average period over which it is expected to be recognized is approximately 1.2 years. Following is a summary of the activity of the restricted stock: Three Months Ended March 31, 2017 Shares Fair Value Balance at December 31, 2016 73,840 $ 51.03 Granted 15,356 $ 65.12 Vested (24,553 ) $ 52.51 Balance at March 31, 2017 64,643 $ 53.81 Performance-Based Restricted Stock On February 2, 2017, the Company granted three-year performance based restricted stock (“PBRS”) awards which are contingent upon the 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 target number of PBRS shares granted was 23,038 with a grant date fair value of $65.12 per share. The 2017 expense related to this grant is currently estimated to be $458,000 and is based on the grant date fair value and the achievement of 100% of the target financial goals.

Retirement Benefits [Abstract]
Defined Pension Plans	Note 9 – Defined Pension Plans The Company has a noncontributory defined-benefit pension 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. Disclosure information is based on a measurement date of December 31 of the corresponding year. The following table represents the components of the net periodic pension costs: Estimated Actual (In thousands) 2017 2016 Service cost – benefits earned during the year $ 3,805 $ 3,559 Interest cost on projected benefit obligations 3,587 3,505 Expected return on plan assets (4,680 ) (4,734 ) Net amortization 1,328 1,259 Net periodic pension cost $ 4,040 $ 3,589 Pension costs recorded to expense were $1,020,000 and $877,000 for the three-month periods ended March 31, 2017 and 2016, respectively. Pension costs increased in 2017 due to a decrease in the discount rate and expected return on plan assets assumptions and the use of the updated mortality tables. The Company made no contribution to the plan during the three-month period ended March 31, 2017 and is evaluating the amount of additional contributions, if any, in the remainder of 2017. In addition to the above funded benefit plan, the Company has an unfunded supplemental executive retirement plan which covers key executives of the Company. This is a noncontributory plan in which the Company and its subsidiaries make accruals designed to fund normal service costs on a current basis using the same method and criteria as its defined benefit plan. The following table represents the components of the net periodic pension costs for 2016 and an estimate for 2017: Estimated Actual (In thousands) 2017 2016 Service cost – benefits earned during the year $ 143 $ 133 Interest cost on projected benefit obligation 361 367 Net amortization 323 295 Net periodic pension cost $ 827 $ 795 Pension costs recorded to expense were $209,000 and $201,000 for the three-month periods ended March 31, 2017 and 2016, respectively.

Income Taxes	Note 10 – Income Taxes As of March 31, 2017, the Company’s unrecognized tax benefits were approximately $1,729,000, of which $1,320,000 would, if recognized, affect the Company’s effective tax rate. As of December 31, 2016, the Company's unrecognized tax benefits were approximately $1,623,000, of which $1,225,000 would, if recognized, affect the Company's effective tax rate. During the next 12 months, the Company may realize a reduction of its unrecognized tax benefits of approximately $253,000 due to the lapse of federal and state statutes of limitations. The Company recognizes interest and penalties related to uncertain tax positions in income tax expense. The Company had $125,000 and $108,000 of gross interest accrued as of March 31, 2017 and December 31, 2016, respectively. There were no penalties for unrecognized tax benefits accrued at March 31, 2017 and December 31, 2016.

Investments, Debt and Equity Securities [Abstract]
Investment in Securities	Note 11 – 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 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 fall into the Level 2 category. The amortized cost, gross unrealized gains, gross unrealized losses and fair value of investment securities are summarized as follows: March 31, 2017 Gross Gross Amortized Unrealized Unrealized (In thousands) Cost Gains Losses Fair Value State and political subdivisions $ 403,011 $ 6,961 $ 2,539 $ 407,433 U.S. government agencies 12,787 — 401 12,386 Certificates of deposit 6,496 — — 6,496 Total $ 422,294 $ 6,961 $ 2,940 $ 426,315 December 31, 2016 Gross Gross Amortized Unrealized Unrealized (In thousands) Cost Gains Losses Fair Value State and political subdivisions $ 368,223 $ 5,239 $ 3,328 $ 370,134 U.S. government agencies 13,075 — 403 12,672 Certificates of deposit 7,746 — — 7,746 Total $ 389,044 $ 5,239 $ 3,731 $ 390,552 The fair values of securities with unrealized losses are as follows: March 31, 2017 Less than 12 months 12 months or more Total Estimated Unrealized Estimated Unrealized Estimated Unrealized (In thousands) Fair Value Losses Fair Value Losses Fair Value Losses State and political subdivisions $ 110,100 $ 2,539 $ — $ — $ 110,100 $ 2,539 U.S. government agencies 12,386 401 — — 12,386 401 Certificates of deposit — — — — — — Total $ 122,486 $ 2,940 $ — $ — $ 122,486 $ 2,940 December 31, 2016 Less than 12 months 12 months or more Total Estimated Unrealized Estimated Unrealized Estimated Unrealized (In thousands) Fair Value Losses Fair Value Losses Fair Value Losses State and political subdivisions $ 140,384 $ 3,328 $ — $ — $ 140,384 $ 3,328 U.S. government agencies 12,672 403 — — 12,672 403 Certificates of deposit — — — — — — Total $ 153,056 $ 3,731 $ — $ — $ 153,056 $ 3,731 There were 76 securities, or 22% of the total (none greater than 12 months), in an unrealized loss position as of March 31, 2017. There were 108 securities, or 31% of the total (none greater than 12 months), in an unrealized loss position as of December 31, 2016. All unrealized losses were reviewed to determine whether the losses were other than temporary. Management believes that all unrealized losses are temporary since they were market driven, and it is more likely than not that the Company will not be required to sell prior to recovery of the amortized basis. The amortized cost and fair value of investment securities by contractual maturity are shown in the following table. Expected maturities may differ from contractual maturities because borrowers have the right to prepay obligations with or without prepayment penalties.

Investment in Securities - The fair value is measured on a recurring basis using Level 2 valuations. Refer to Note 11, “Investment in Securities,” for fair value and unrealized gains and losses by investment type. Loans - The fair value is estimated using present values of future cash flows discounted at risk-adjusted interest rates for each loan category designated by management and is therefore a Level 3 valuation. Management believes that the risk factor embedded in the interest rates along with the allowance for loan losses result in a fair valuation. Impaired loans are valued using the fair value of the collateral which is based upon an observable market price or a current appraised value and therefore, the fair value is a nonrecurring Level 3 valuation. Accrued Interest Receivable - The carrying amount approximates fair value. Deposits - The fair value of demand deposits, savings deposits and certain money market deposits is the amount payable on demand at the reporting date. The fair value of fixed-maturity certificates of deposit is estimated using the rates currently offered for deposits of similar remaining maturities and therefore, is a Level 2 valuation. The fair value estimates above do not include the benefit that results from the low-cost funding provided by the deposit liabilities compared to the cost of borrowing funds in the market or the benefit derived from the customer relationship inherent in existing deposits. Accounts and Drafts Payable - The carrying amount approximates fair value. Accrued Interest - The carrying amount approximates fair value. There were no transfers between Levels 1 and 2 of the fair value hierarchy for the three months ended March 31, 2017 and 2016. No financial instruments are measured using Level 3 inputs for the three months ended March 31, 2017 and 2016.
