	Note 1
	Summary of Significant Accounting Policies
	Summary of Operations Cass Information Systems, Inc. (the "Company") provides payment and information services, which include processing and payment of transportation, energy, telecommunications and environmental invoices. These services include the acquisition and management of data, information delivery and financial exchange. The consolidated balance sheet captions, "Accounts and drafts payable" and "Payments in excess of funding," represent the Company's resulting financial position related to the payment services that are performed for customers. The Company also provides a full range of banking services to individual, corporate and institutional customers through Cass Commercial Bank (the "Bank"), its wholly owned bank subsidiary.
	Basis of Presentation The accounting and reporting policies of the Company and its subsidiaries conform to U.S. generally accepted accounting principles. The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries after elimination of intercompany transactions. Certain amounts in the 2012 and 2011 consolidated financial statements have been reclassified to conform to the 2013 presentation. Such reclassifications have no effect on previously reported net income or shareholders' equity. The Company issued a 10% stock dividend on December 14, 2012. The share and per share information have been restated for this dividend unless indicated otherwise for all periods presented in the accompanying consolidated financial statements.
	Use of Estimates In preparing the consolidated financial statements, Company management is required to make estimates and assumptions which significantly affect the reported amounts in the consolidated financial statements.
	Cash and Cash Equivalents For purposes of the consolidated statements of cash flows, the Company considers cash and due from banks, interest-bearing deposits in other financial institutions, federal funds sold and other short-term investments as segregated in the accompanying consolidated balance sheets to be cash equivalents.
	Investment in Debt Securities The Company classifies its debt marketable securities as available-for-sale. Securities classified as available-for-sale are carried at fair value. Unrealized gains and losses, net of the related tax effect, are excluded from earnings and reported in accumulated other comprehensive income, a component of shareholders' equity. A decline in the fair value of any available-for-sale security below cost that is deemed other than temporary results in a charge to earnings and the establishment of a new cost basis for the security. To determine whether impairment is other than temporary, the Company considers whether it is more likely than not that the Company will not be required to sell prior to recovery of the amortized cost basis. Evidence considered in this assessment includes 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.
	Allowance for Loan Losses The allowance for loan losses is increased by provisions charged to expense and is available to absorb charge-offs, net of recoveries. Management utilizes a systematic, documented approach in determining the appropriate level of the allowance for loan losses. Management's approach, which provides for general and specific allocations, is based on current economic conditions, past losses, collection experience, risk characteristics of the portfolio, assessments of collateral values by obtaining independent appraisals for significant properties, and such other factors which, in management's judgment, deserve current recognition in estimating loan losses.
	Management believes the allowance for loan losses is adequate to absorb probable losses in the loan portfolio. While management uses all available information to recognize losses on loans, future additions to the allowance may be necessary based on changes in economic conditions. Additionally, various regulatory agencies, as an integral part of their examination process, periodically review the Company's allowance for loan losses. Such agencies may require the Company to increase the allowance for loan losses based on their judgments and interpretations about information available to them at the time of their examination.
	Premises and Equipment Premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation is computed over the estimated useful lives of the assets, or the respective lease terms for leasehold improvements, using straight-line and accelerated methods. Estimated useful lives do not exceed 40 years for buildings, the lesser of 10 years or the life of the lease for leasehold improvements and range from 3 to 7 years for software, equipment, furniture and fixtures. Maintenance and repairs are charged to expense as incurred.
	Intangible Assets Cost in excess of fair value of net assets acquired has resulted from business acquisitions. Goodwill and intangible assets with indefinite useful lives are not amortized, but instead are tested for impairment at least annually. Intangible assets with definite useful lives are amortized on a straight-line basis over their respective estimated useful lives.
	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 The Company accounts for non-marketable equity investments, in which it holds less than a 20% ownership, under the cost method. Under the cost method of accounting, investments are carried at cost and are adjusted only for other than temporary declines in fair value, distributions of earnings and additional investments. The Company periodically evaluates whether any declines in fair value of its investments are other than temporary. In performing this evaluation, the Company considers various factors including any decline in market price, where available, the investee's financial condition, results of operations, operating trends and other financial ratios. Non-marketable equity investments are included in other assets on the consolidated balance sheets.
	Foreclosed Assets Real estate acquired as a result of foreclosure is initially recorded at fair value less estimated selling costs. Fair value is generally determined through the receipt of appraisals. Any write down to fair value at the time the property is acquired is recorded as a charge-off to the allowance for loan losses. Any decline in the fair value of the property subsequent to acquisition is recorded as a charge to non-interest expense.
	Treasury Stock Purchases of the Company's common stock are recorded at cost. Upon reissuance, treasury stock is reduced based upon the average cost basis of shares held.
	Comprehensive Income Comprehensive income consists of net income, changes in net unrealized gains (losses) on available-for-sale securities and pension liability adjustments and is presented in the accompanying consolidated statements of shareholders' equity and consolidated statements of comprehensive income.
	Loans Interest on loans is recognized based upon the principal amounts outstanding. It is the Company's policy to discontinue the accrual of interest when there is reasonable doubt as to the collectability of principal or interest. Subsequent payments received on such loans are applied to principal if there is any doubt as to the collectability of such principal; otherwise, these receipts are recorded as interest income. The accrual of interest on a loan is resumed when the loan is current as to payment of 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.
	Impairment of Loans A loan is considered impaired when it is probable that a creditor will be unable to collect all amounts due, both principal and interest, according to the contractual terms of the loan agreement. When measuring impairment, the expected future cash flows of an impaired loan are discounted at the loan's effective interest rate. Alternatively, impairment could be measured by reference to an observable market price, if one exists, or the fair value of the collateral for a collateral-dependent loan. Regardless of the historical measurement method used, the Company measures impairment based on the fair value of the collateral when the Company determines foreclosure is probable. Additionally, impairment of a restructured loan is measured by discounting the total expected future cash flows at the loan's effective rate of interest as stated in the original loan agreement. The Company uses its nonaccrual methods as discussed above for recognizing interest on impaired loans.
	Information Services Revenue A majority of the Company's revenues are attributable to fees for providing services. These services include transportation invoice rating, payment processing, auditing, and the generation of accounting, transportation and environmental information. The Company also processes, pays and generates management information from electric, gas, telecommunications and other invoices. The specific payment and information processing services provided to each customer are developed individually to meet each customer's specific requirements. The Company enters into service agreements with customers typically for fixed fees per transaction that are invoiced monthly. Revenues are recognized in the period services are rendered and earned under the service agreements, as long as collection is reasonably assured.
	Income Taxes Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. Deferred tax assets are reduced if necessary, by a deferred tax asset valuation allowance. In the event that management determines it will not be able to realize all or part of net deferred tax assets in the future, the Company adjusts the recorded value of deferred tax assets, which would result in a direct charge to income tax expense in the period that such determination is made. Likewise, the Company will reverse the valuation allowance when realization of the deferred tax asset is expected. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.
	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.
	Stock-Based Compensation The Company follows Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC"), "Accounting for Stock Options and Other Stock-based Compensation" ("ASC 718"), which requires that all stock-based compensation be recognized as an expense in the financial statements and that such cost be measured at the fair value of the award. FASB ASC 718 also requires that excess tax benefits related to stock option exercises and restricted stock awards be reflected as financing cash inflows instead of operating cash inflows.
	Pension Plans The amounts recognized in the consolidated financial statements related to pension are determined from actuarial valuations. Inherent in these valuations are assumptions including expected return on plan assets, discount rates at which the liabilities could be settled at December 31, 2013, rate of increase in future compensation levels and mortality rates. These assumptions are updated annually and are disclosed in Note 10. The Company follows FASB ASC 715, "Compensation - Retirement Benefits" ("ASC 715") which requires companies to recognize the overfunded or underfunded status of a defined benefit postretirement plan as an asset or liability in its consolidated balance sheet and to recognize changes in that funded status in the year in which the changes occur through comprehensive income. The funded status is measured as the difference between the fair value of the plan assets and the projected benefit obligation as of the date of its fiscal year-end. There have been no significant changes in the Company's long-term rate of return assumptions for the past three fiscal years ended December 31, 2013 and management believes they are not reasonably likely to change in the future.
	Fair Value Measurements The Company follows the provisions of FASB ASC 820, "Fair Value Measurements and Disclosures", which defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and outlines disclosures about fair value measurements. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. A three-level hierarchy for valuation techniques is used to measure financial assets and financial liabilities at fair value. This hierarchy is based on whether the valuation inputs are observable or unobservable. Financial instrument valuations are considered Level 1 when they are based on quoted prices in active markets for identical assets or liabilities. Level 2 financial instrument valuations use quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. Financial instrument valuations are considered Level 3 when they are determined using pricing models, discounted cash flow methodologies or similar techniques and at least one significant model assumption or input is unobservable, and when determination of the fair value requires significant management judgment or estimation. The Company records securities available for sale at their fair values on a recurring basis using Level 2 valuations. Additionally, the Company records impaired loans and other real estate owned at their fair value on a nonrecurring basis. The nonrecurring fair value adjustments typically involve application of lower-of-cost-or-market accounting or impairment write-downs of individual assets.

	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 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 to risk-weighted assets, and of Tier I capital to average assets. Management believes that as of December 31, 2013 and 2012, 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 revise 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 incorporates changes required by the Dodd-Frank 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 will come into effect for the Company and the Bank on January 1, 2015 (subject to a phase-in period).
	The Bank is also subject to the regulatory framework for prompt corrective action. As of December 31, 2013 and 2012, 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, 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.
	Subsidiary dividends are a significant source of funds for payment of dividends by the Company to its shareholders. At December 31, 2013, unappropriated retained earnings of $24,440,000 were available at the Bank for the declaration of dividends to the Company without prior approval from regulatory authorities. However, dividends paid by the Bank to the Company would be prohibited if the effect thereof would cause the Bank's capital to be reduced below applicable minimum capital requirements.
	There were no restricted funds on deposit used to meet regulatory reserve requirements at December 31, 2013 and 2012.
	The Company's and the Bank's actual and required capital amounts and ratios as are as follows:

	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, 2013 and 2012 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:

	There were 102 securities, or 31% of total, (3 greater than 12 months) in an unrealized loss position as of December 31, 2013 compared to 18 securities (none greater than 12 months) in an unrealized loss position as of December 31, 2012 . 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, 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 debt and equity 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.

	The premium related to the purchase of state and political subdivisions was $4,450,000 and $4,384,000 in 2013 and 2012, respectively.
	The amortized cost of debt securities pledged to secure public deposits, securities sold under agreements to repurchase and for other purposes at December 31, 2013 and 2012 were $3,750,000.
	Proceeds from sales of debt securities classified as available-for-sale were $95,742,000 in 2013, $69,747,000 in 2012, and $5,930,000 in 2011. Gross realized gains on the sales in 2013, 2012 and 2011 were $4,295,000, $2,646,000, and $48,000, respectively. Gross realized losses on sales in 2013, 2012 and 2011 were $271,000, $11,000, and $5,000, respectively.

	Loans
	The Company originates commercial, industrial and real estate loans to businesses and churches throughout the metropolitan St. Louis, Missouri area, Orange County, California and other selected cities in the United States. The Company does not have any particular concentration of credit in any one economic sector; however, a substantial portion of the commercial and industrial loans are extended to privately-held commercial companies in these market areas, and are generally secured by the assets of the business. The Company also has a substantial portion of real estate loans secured by mortgages that are extended to churches in its market area and selected cities in the United States.

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. The allowance for loan losses related to impaired loans was $318,000 and $1,404,000 at December 31, 2013 and 2012, respectively. There were no impaired loans without a valuation allowance at December 31, 2013 or 2012. Nonaccrual loans were $1,797,000 and $6,572,000 at December 31, 2013 and 2012, respectively. Loans delinquent 90 days or more and still accruing interest were $0 at December 31, 2013 and 2012. At December 31, 2013 and 2012, there were no loans classified as troubled debt restructuring. The average balances of impaired loans during 2013, 2012 and 2011 were $1,381,000, $5,451,000 and $5,276,000, respectively. Income that would have been recognized on non-accrual loans under the original terms of the contract was $180,000, $381,000 and $107,000 for 2013, 2012 and 2011, respectively. Income that was recognized on nonaccrual loans was $131,000, $141,000 and $102,000 for 2013, 2012 and 2011 respectively. There were no foreclosed loans as of December 31, 2013.

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, "Allowance for Credit Losses." At December 31, 2013, all impaired loans were evaluated based on the fair value of the collateral. 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.

	The Company accounts for intangible assets in accordance with FASB ASC 350, "Goodwill and Other Intangible Assets" ("ASC 350"), which requires that intangibles with indefinite useful lives be tested annually for impairment and those with finite useful lives be amortized over their useful lives.
	In January 2012, the Company acquired the assets of Waste Reduction Consultants, Inc., and recorded intangible assets of $3,183,000 for the customer list, $261,000 for two non-compete agreements and software of $234,000. Details of the Company's intangible assets are as follows:

	Issued under stock-based compensation plan	30,407
	SARs exercised	27,242
	Shares outstanding at December 31	11,521,480
	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. 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
	Defined Benefit Plan
	The Company has a noncontributory defined-benefit pension plan (the "Plan"), which covers most of its employees. 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)		2013				2012
	Projected benefit obligation:
	Balance, January 1		$	67,087			$	53,972

	Funded status:
	Accrued pension asset (liability)		$	7,188			$	(5,703	)
	The following represent the major assumptions used to determine the projected benefit obligation of the Plan. For 2013, 2012 and 2011, the Plan's expected benefit cash flows were discounted using the Citibank Above Median Curve.
			2013			2012			2011
	Weighted average discount rate		5	%		4.25	%		4.75	%
	Rate of increase in compensation levels		3.75	%		3.75	%		4	%
	The accumulated benefit obligation was $52,187,000 and $54,094,000 as of December 31, 2013 and 2012, respectively. The Company expects to contribute approximately $2,000,000 to the Plan in 2014. The following pension benefit payments, which reflect expected future service, as appropriate, are expected to be paid by the Plan:
			Amount
	2014		$	1,583,000
	2015			1,706,000
	2016			1,909,000
	2017			2,113,000
	2018			2,524,000
	2019-2023			16,411,000
	The Plan's pension cost included the following components:
			For the Year Ended
			December 31,
	(In thousands)		2013				2012				2011
	Service cost - benefits earned during the year		$	3,452			$	2,799			$	2,073

	Expected return on plan assets			(4,469	)			(3,967	)			(3,314	)
	Net amortization and deferral			1,729				1,473				603
	Net periodic pension cost		$	3,531			$	2,875			$	1,785
	The following represent the major assumptions used to determine the net pension cost of the Plan:
			2013			2012			2011
	Weighted average discount rate		4.25	%		4.75	%		5.75	%
	Rate of increase in compensation levels		3.75	%		4	%		4	%
	Expected long-term rate of return on assets		7.25	%		7.25	%		7.25	%
	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 50% fixed income, 34% U.S. equity and 16% 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 assumed long-term rate of return on assets is 7.00%. The expected one year nominal returns and annual standard deviations are shown by asset class below:
			% of Total			One-Year Nominal			Annual Standard
	Asset Class		Portfolio			Return			Deviation
	Core Fixed Income		50	%		4.59	%		6.45	%
	Large Cap U.S. Equities		27	%		8.06	%		17.8	%
	Small Cap U.S. Equities		7	%		9.82	%		26.2	%
	International (Developed)		15	%		8.21	%		20.4	%
	International (Emerging)		1	%		11.13	%		31.15	%
	Applying appropriate correlation factors between each of the asset classes and based on a distribution of geometric returns over a 30-year period, a reasonable range of returns is expected to be 4.77% to 7.27%. The 7.00% assumption falls within the expected range.

Supplemental Executive Retirement Plan
The Company also has an unfunded supplemental executive retirement plan ("SERP") which covers key executives of the Company. 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, funded status and amounts recognized in the Company's consolidated balance sheets is as follows:
		December 31,
(In thousands)		2013				2012
Benefit obligation:

Weighted average discount rate		4.75	%		4	%		4.5	%
Rate of increase in compensation levels		3.75	%		3.75	%		4	%
The accumulated benefit obligation was $5,917,000 and $6,200,000 as of December 31, 2013 and 2012, respectively. Since this is an unfunded plan there are no plan assets. Benefits paid were $236,000 in 2013, $236,000 in 2012 and $236,000 in 2011. Expected future benefits payable by the Company over the next 10 years are as follows:
	Amount
2014	$	236,000
2015		235,000
2016		245,000
2017		260,000
2018		340,000
2019-2023		2,564,000
The SERP's pension cost included the following components:
		For the Year Ended December 31,

Total		$	11,479		$	26,401		$	3,075		$	4,304
The estimated pre-tax prior service cost and net actuarial loss in accumulated other comprehensive loss at December 31, 2013 expected to be recognized as components of net periodic benefit cost in 2014 for the Plan are $3,073,000 and $386,000, respectively. The estimated pre-tax prior service cost and net actuarial loss in accumulated other comprehensive loss at December 31, 2013 expected to be recognized as components of net periodic benefit cost in 2014 for the SERP are $136,000 and $431,000 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 the consolidated statements of income in 2013, 2012 and 2011 was $5,065,000, $5,213,000, and $5,270,000, 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 2013, 2012 and 2011 were $591,000, $537,000, and $497,000, respectively.

	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.
	All share and per share data have been restated to give effect to the 10% stock dividend issued on December 14, 2012.
	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 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. Changes in restricted shares outstanding for the year ended December 31, 2013 were as follows:
						Weighted Average
						Grant Date
			Shares			Fair Value
	Balance at December 31, 2012		54,875			$	31.61
	Granted		30,407			$	42.21
	Vested		(26,633	)		$	30.86
	Balance at December 31, 2013		58,649			$	37.45
	During 2012 and 2011, 28,370 and 31,472 shares, respectively, were granted with weighted average per share market values at date of grant of $34.03 in 2012 and $30.05 in 2011. The fair value of such shares, which is based on the market price on the date of grant, is amortized to expense over the three-year vesting period. Amortization of the restricted stock bonus awards totaled $1,176,000 for 2013, $788,000 for 2012 and $787,000 for 2011. As of December 31, 2013, the total unrecognized compensation expense related to non-vested restricted stock awards was $1,131,000 and the related weighted average period over which it is expected to be recognized is approximately 0.64 years. The total fair value of shares vested during the years ended December 2013, 2012, and 2011 was $822,000, $788,000, and $812,000 respectively.
	SARs
	There were 85,943 SARs granted during the year ended December 31, 2013. The Company uses the Black-Scholes option-pricing model to determine the fair value of the SARs at the date of grant. Following are the assumptions used to estimate the $10.69 per share fair value.
		Year Ended December 31, 2013
	Risk-free interest rate	1.29	%
	Expected life	7 years
	Expected volatility	28.72	%
	Expected dividend yield	1.71	%
	The risk-free interest rate is based on the zero-coupon U.S. Treasury yield for the period equal to the expected life of the SARs at the time of the grant. The expected life was derived using the historical exercise activity. The Company uses historical volatility for a period equal to the expected life of the SARs using average monthly closing market prices of the Company's stock. The expected dividend yield is determined based on the Company's current rate of annual dividends.
	During 2013, the Company recognized SARs expense of $800,000. As of December 31, 2013, the total unrecognized compensation expense related to SARs was $945,000, and the related weighted average period over which it is expected to be recognized is 1.13 years. Changes in SARs outstanding for the year ended December 31, 2013 were as follows:
		SARs			Weighted Average Exercise Price
	Balance at December 31, 2012	351,881			$	27.52
	Granted	85,943			$	42.14
	Exercised	(94,379	)		$	24.67
	Balance at December 31, 2013	343,445			$	32.01
	Exercisable at December 31, 2013	166,317			$	26.58
	The total intrinsic value of SARs exercised during 2013 and 2012 was $2,328,000 and $1,769,000, respectively. The average remaining contractual term for SARs outstanding as of December 31, 2013 was 7.33 years and the aggregate intrinsic value was $12,137,000. The average remaining contractual term for SARs exercisable as of December 31, 2012 was 7.34 years and the aggregate intrinsic value was $4,988,000.
	The total compensation cost for share-based payment arrangements was $1,976,000, $1,398,000, and $1,391,000 in 2013, 2012, and 2011, respectively. The total unrecognized tax benefit related to share based compensation was $55,000, $55,000, and $316,000 in 2013, 2012, and 2011, respectively.

	1 As of December 31, 2013, the Company had approximately $852,000 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 2020.
	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, 2013 or 2012, due to management's belief that all criteria for recognition have been met, including the existence of a history of taxes paid sufficient to support the realization of deferred tax assets.

	At December 31, 2013, 2012 and 2011, the balance of the Company's unrecognized tax benefits which would, if recognized, affect the Company's effective tax rate was $861,000, $1,357,000 and $1,496,000, respectively. These amounts are net of the offsetting benefits from other taxing jurisdictions.
	As of December 31, 2013, 2012 and 2011, the Company had $41,000, $89,000 and $95,000, respectively, in accrued interest related to unrecognized tax benefits. During 2013 and 2012, the Company recorded a net reduction in accrued interest of $48,000 and $6,000, respectively, as a result of settlements with taxing authorities and other prior-year adjustments.
	The Company believes it is reasonably possible that the total amount of tax benefits will decrease by approximately $251,000 over the next twelve 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 2010 through 2012 remain subject to examination by the Internal Revenue Service. In addition, the Company is subject to state tax examinations for the tax years 2009 through 2012.

	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, 2013 and 2012, 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)	2013		2012
	Conditional commitments to extend credit	$	5,596	$	14,847
	Standby letters of credit		13,168		13,316
	Commercial letters of credit		3,325		3,069
	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.
	Following is a summary of the carrying amounts and fair values of the Company's financial instruments:

	The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value:
	Cash and Cash EquivalentsThe carrying amount approximates fair value.
	Investment in SecuritiesThe fair value is measured on a recurring basis using Level 2 valuations. Refer to Note 3, "Investment in Securities," for fair value and unrealized gains and losses by investment type.
	LoansThe 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 results in a fair valuation.
	Impaired loans are valued using the fair value of the collateral which is based upon an observable market price or current appraised value and therefore, the fair value is a nonrecurring Level 3 valuation.
	Accrued Interest ReceivableThe 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 PayableThe carrying amount approximates fair value.
	Accrued InterestThe carrying amount approximates fair value.
	Limitations Fair value estimates are based on existing on- and off-balance sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. Other significant assets or liabilities that are not considered financial assets or liabilities include premises and equipment and the benefit that results from the low-cost funding provided by the deposit liabilities compared to the cost of borrowing funds in the market (core deposit intangible). In addition, tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in any of the estimates.

Industry Segment Information [Abstract]	'
Industry Segment Information	'
	Note 16
	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 Note 1 of this report. 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. Loans are sold by Banking Services to Information Services to create liquidity when the Bank's loan to deposit ratio is greater than 100%. 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 for the years ended December 31, 2013, 2012 and 2011, is as follows:

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2013
Summary of Significant Accounting Policies [Abstract]	'
Summary of Operations	'
	Summary of Operations Cass Information Systems, Inc. (the "Company") provides payment and information services, which include processing and payment of transportation, energy, telecommunications and environmental invoices. These services include the acquisition and management of data, information delivery and financial exchange. The consolidated balance sheet captions, "Accounts and drafts payable" and "Payments in excess of funding," represent the Company's resulting financial position related to the payment services that are performed for customers. The Company also provides a full range of banking services to individual, corporate and institutional customers through Cass Commercial Bank (the "Bank"), its wholly owned bank subsidiary.
Basis of Presentation	'
	Basis of Presentation The accounting and reporting policies of the Company and its subsidiaries conform to U.S. generally accepted accounting principles. The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries after elimination of intercompany transactions. Certain amounts in the 2012 and 2011 consolidated financial statements have been reclassified to conform to the 2013 presentation. Such reclassifications have no effect on previously reported net income or shareholders' equity. The Company issued a 10% stock dividend on December 14, 2012. The share and per share information have been restated for this dividend unless indicated otherwise for all periods presented in the accompanying consolidated financial statements.
Use of Estimates	'
	Use of Estimates In preparing the consolidated financial statements, Company management is required to make estimates and assumptions which significantly affect the reported amounts in the consolidated financial statements.
Cash and Cash Equivalents	'
	Cash and Cash Equivalents For purposes of the consolidated statements of cash flows, the Company considers cash and due from banks, interest-bearing deposits in other financial institutions, federal funds sold and other short-term investments as segregated in the accompanying consolidated balance sheets to be cash equivalents.
Investment in Debt Securities	'
	Investment in Debt Securities The Company classifies its debt marketable securities as available-for-sale. Securities classified as available-for-sale are carried at fair value. Unrealized gains and losses, net of the related tax effect, are excluded from earnings and reported in accumulated other comprehensive income, a component of shareholders' equity. A decline in the fair value of any available-for-sale security below cost that is deemed other than temporary results in a charge to earnings and the establishment of a new cost basis for the security. To determine whether impairment is other than temporary, the Company considers whether it is more likely than not that the Company will not be required to sell prior to recovery of the amortized cost basis. Evidence considered in this assessment includes 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.
Allowance for Loan Losses	'
	Allowance for Loan Losses The allowance for loan losses is increased by provisions charged to expense and is available to absorb charge-offs, net of recoveries. Management utilizes a systematic, documented approach in determining the appropriate level of the allowance for loan losses. Management's approach, which provides for general and specific allocations, is based on current economic conditions, past losses, collection experience, risk characteristics of the portfolio, assessments of collateral values by obtaining independent appraisals for significant properties, and such other factors which, in management's judgment, deserve current recognition in estimating loan losses.
	Management believes the allowance for loan losses is adequate to absorb probable losses in the loan portfolio. While management uses all available information to recognize losses on loans, future additions to the allowance may be necessary based on changes in economic conditions. Additionally, various regulatory agencies, as an integral part of their examination process, periodically review the Company's allowance for loan losses. Such agencies may require the Company to increase the allowance for loan losses based on their judgments and interpretations about information available to them at the time of their examination.
Premises and Equipment	'
	Premises and Equipment Premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation is computed over the estimated useful lives of the assets, or the respective lease terms for leasehold improvements, using straight-line and accelerated methods. Estimated useful lives do not exceed 40 years for buildings, the lesser of 10 years or the life of the lease for leasehold improvements and range from 3 to 7 years for software, equipment, furniture and fixtures. Maintenance and repairs are charged to expense as incurred.
Intangible Assets	'
	Intangible Assets Cost in excess of fair value of net assets acquired has resulted from business acquisitions. Goodwill and intangible assets with indefinite useful lives are not amortized, but instead are tested for impairment at least annually. Intangible assets with definite useful lives are amortized on a straight-line basis over their respective estimated useful lives.
	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	'
	Non-marketable Equity Investments The Company accounts for non-marketable equity investments, in which it holds less than a 20% ownership, under the cost method. Under the cost method of accounting, investments are carried at cost and are adjusted only for other than temporary declines in fair value, distributions of earnings and additional investments. The Company periodically evaluates whether any declines in fair value of its investments are other than temporary. In performing this evaluation, the Company considers various factors including any decline in market price, where available, the investee's financial condition, results of operations, operating trends and other financial ratios. Non-marketable equity investments are included in other assets on the consolidated balance sheets.
Foreclosed Assets	'
	Foreclosed Assets Real estate acquired as a result of foreclosure is initially recorded at fair value less estimated selling costs. Fair value is generally determined through the receipt of appraisals. Any write down to fair value at the time the property is acquired is recorded as a charge-off to the allowance for loan losses. Any decline in the fair value of the property subsequent to acquisition is recorded as a charge to non-interest expense.
Treasury Stock	'
	Treasury Stock Purchases of the Company's common stock are recorded at cost. Upon reissuance, treasury stock is reduced based upon the average cost basis of shares held.
Comprehensive Income	'
	Comprehensive Income Comprehensive income consists of net income, changes in net unrealized gains (losses) on available-for-sale securities and pension liability adjustments and is presented in the accompanying consolidated statements of shareholders' equity and consolidated statements of comprehensive income.
Loans	'
	Loans Interest on loans is recognized based upon the principal amounts outstanding. It is the Company's policy to discontinue the accrual of interest when there is reasonable doubt as to the collectability of principal or interest. Subsequent payments received on such loans are applied to principal if there is any doubt as to the collectability of such principal; otherwise, these receipts are recorded as interest income. The accrual of interest on a loan is resumed when the loan is current as to payment of 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.
Impairment of Loans	'
	Impairment of Loans A loan is considered impaired when it is probable that a creditor will be unable to collect all amounts due, both principal and interest, according to the contractual terms of the loan agreement. When measuring impairment, the expected future cash flows of an impaired loan are discounted at the loan's effective interest rate. Alternatively, impairment could be measured by reference to an observable market price, if one exists, or the fair value of the collateral for a collateral-dependent loan. Regardless of the historical measurement method used, the Company measures impairment based on the fair value of the collateral when the Company determines foreclosure is probable. Additionally, impairment of a restructured loan is measured by discounting the total expected future cash flows at the loan's effective rate of interest as stated in the original loan agreement. The Company uses its nonaccrual methods as discussed above for recognizing interest on impaired loans.
Information Services Revenue	'
	Information Services Revenue A majority of the Company's revenues are attributable to fees for providing services. These services include transportation invoice rating, payment processing, auditing, and the generation of accounting, transportation and environmental information. The Company also processes, pays and generates management information from electric, gas, telecommunications and other invoices. The specific payment and information processing services provided to each customer are developed individually to meet each customer's specific requirements. The Company enters into service agreements with customers typically for fixed fees per transaction that are invoiced monthly. Revenues are recognized in the period services are rendered and earned under the service agreements, as long as collection is reasonably assured.
Income Taxes	'
	Income Taxes Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. Deferred tax assets are reduced if necessary, by a deferred tax asset valuation allowance. In the event that management determines it will not be able to realize all or part of net deferred tax assets in the future, the Company adjusts the recorded value of deferred tax assets, which would result in a direct charge to income tax expense in the period that such determination is made. Likewise, the Company will reverse the valuation allowance when realization of the deferred tax asset is expected. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.
Earnings Per Share	'
	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.
Share-Based Compensation	'
	Stock-Based Compensation The Company follows Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC"), "Accounting for Stock Options and Other Stock-based Compensation" ("ASC 718"), which requires that all stock-based compensation be recognized as an expense in the financial statements and that such cost be measured at the fair value of the award. FASB ASC 718 also requires that excess tax benefits related to stock option exercises and restricted stock awards be reflected as financing cash inflows instead of operating cash inflows.
Pension Plans	'
	Pension Plans The amounts recognized in the consolidated financial statements related to pension are determined from actuarial valuations. Inherent in these valuations are assumptions including expected return on plan assets, discount rates at which the liabilities could be settled at December 31, 2013, rate of increase in future compensation levels and mortality rates. These assumptions are updated annually and are disclosed in Note 10. The Company follows FASB ASC 715, "Compensation - Retirement Benefits" ("ASC 715") which requires companies to recognize the overfunded or underfunded status of a defined benefit postretirement plan as an asset or liability in its consolidated balance sheet and to recognize changes in that funded status in the year in which the changes occur through comprehensive income. The funded status is measured as the difference between the fair value of the plan assets and the projected benefit obligation as of the date of its fiscal year-end. There have been no significant changes in the Company's long-term rate of return assumptions for the past three fiscal years ended December 31, 2013 and management believes they are not reasonably likely to change in the future.
Fair Value Measurements	'
	Fair Value Measurements The Company follows the provisions of FASB ASC 820, "Fair Value Measurements and Disclosures", which defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and outlines disclosures about fair value measurements. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. A three-level hierarchy for valuation techniques is used to measure financial assets and financial liabilities at fair value. This hierarchy is based on whether the valuation inputs are observable or unobservable. Financial instrument valuations are considered Level 1 when they are based on quoted prices in active markets for identical assets or liabilities. Level 2 financial instrument valuations use quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. Financial instrument valuations are considered Level 3 when they are determined using pricing models, discounted cash flow methodologies or similar techniques and at least one significant model assumption or input is unobservable, and when determination of the fair value requires significant management judgment or estimation. The Company records securities available for sale at their fair values on a recurring basis using Level 2 valuations. Additionally, the Company records impaired loans and other real estate owned at their fair value on a nonrecurring basis. The nonrecurring fair value adjustments typically involve application of lower-of-cost-or-market accounting or impairment write-downs of individual assets.
