Note 2 – Intangible Assets

The Company accounts for intangible assets in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 350, “Goodwill and Other Intangible Assets,” 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. (“WRC”), 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:

The customer lists are amortized over seven and ten years; the non-compete agreements over five years; software over three years and other intangible assets over 15 years. Amortization of intangible assets amounted to $433,000 and $80,000 for the nine-month periods ended September 30, 2012 and 2011, respectively. Estimated amortization of intangibles over the next five years is as follows: $581,000 in 2012, $535,000 in 2013, $482,000 in 2014 and $404,000 in 2015 and 2016.

Earnings Per Share [Abstract]

Earnings Per Share [Text Block]

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-month and nine-month periods ended September 30, 2012 and 2011. The calculations of basic and diluted earnings per share are as follows:

Industry Segment Information Disclosure [Abstract]

Segment Reporting Disclosure [Text Block]

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 freight, utility, telecommunication and environmental invoice processing and payment services primarily 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, 2011. 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 North America, 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 there is no allocation methodology used. Loans are sold by Banking Services to Information Services to create liquidity when the loan-to-deposit ratio of the Company’s bank subsidiary, Cass Commercial Bank (the “Bank”) 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 is as follows:

¹		Loans subject to normal monitoring involve borrowers of acceptable-to-strong credit quality and risk, who have the apparent ability to satisfy their loan obligation.
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 nonperforming. 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 September 30, 2012 and December 31, 2011, 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 2. Loans delinquent 90 days or more and still accruing interest at September 30, 2012 and December 31, 2011 were $0 and $29,000, respectively. Loans classified as troubled debt restructuring were $0 and $4,479,000 at September 30, 2012 and December 31, 2011, respectively.

There are two foreclosed loans with a book value of $1,322,000 which have been recorded as other real estate owned (included in other assets) as of September 30, 2012 and there were two foreclosed loans with a book value of $1,689,000 as of December 31, 2011. During the three months ended September 30, 2012, one property located in St. Louis County, Missouri, was sold resulting in a net gain of $2,000 and a property relating to a loan secured by commercial real estate, also located in St. Louis County, Missouri, was added through foreclosure.

The following table presents the recorded investment and unpaid principal balance for impaired loans at September 30, 2012 and December 31, 2011:

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies Disclosure [Text Block]

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 September 30, 2012 and December 31, 2011, 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 September 30, 2012, the balance of unused loan commitments, standby and commercial letters of credit were $12,046,000, $13,594,000 and $4,203,000, 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 September 30, 2012:

	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	$	8,263	$	1,009	$	2,096	$	1,665	$	3,493
Time deposits		128,739		121,005		6,278		1,456		—
Total	$	137,002	$	122,014	$	8,374	$	3,121	$	3,493

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.

Stock-Based Compensation

9 Months Ended

Sep. 30, 2012

Disclosure Of Compensation Related Costs, Share-Based Payments [Abstract]

Disclosure of Compensation Related Costs, Share-based Payments [Text Block]

Note 8 – Stock-Based Compensation

The 2007 Omnibus Incentive Stock Plan (the “Omnibus Plan”) permits the issuance of up to 968,000 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 issues shares out of treasury stock for these awards. During the Nine Months Ended September 30, 2012, 25,805 restricted shares and 83,968 SARs were granted under the Omnibus Plan.

The Company also continues to maintain its other stock-based incentive plans for the restricted common stock previously awarded and the options previously issued and still outstanding. These plans have been superseded by the Omnibus Plan and accordingly, any available restricted stock and stock option grants not yet issued have been cancelled.

Restricted Stock
Restricted shares are amortized to expense over the three-year vesting period. As of September 30, 2012, the total unrecognized compensation expense related to non-vested common stock was $1,270,000, and the related weighted-average period over which it is expected to be recognized is approximately 1.1 years.

Following is a summary of the activity of the restricted stock:

	Nine Months Ended

	Shares		Fair Value
Balance at December 31, 2011	52,470		$	29.86
Granted	25,805		$	37.43
Vested	(28,154	)	$	28.02
Balance at September 30, 2012	50,121		$	34.79

Stock Options
Stock options vest and expire over a period not to exceed seven years. As of September 30, 2012, the total unrecognized compensation expense related to non-vested stock options was $4,000, and the related weighted-average period over which it is expected to be recognized is approximately .3 years. Following is a summary of the activity of the stock options during the nine-month period ended September 30, 2012:

		Weighted-		Average	Aggregate
		Average		Remaining	Intrinsic
		Exercise		Contractual	Value
	Shares	Price		Term Years	*(In thousands)*
Outstanding at December 31, 2011	30,628	$	17.79	.84	$	545

Exercisable at September 30, 2012	17,436	$	18.79	.26	$	404

The total intrinsic value of options exercised was $283,000 and $156,000 for the nine-month periods ended September 30, 2012 and 2011, respectively. Following is a summary of the activity of the non-vested stock options during the nine-month period ended September 30, 2012:

			Weighted- Average
	Shares		Grant Date Fair Value
Non-vested at December 31, 2011	3,674		$	2.69
Vested	(3,674	)	$	2.69
Non-vested at September 30, 2012	—		$	0.00

SARs
SARs vest over a three-year period, with one-third of the shares vesting and becoming exercisable each year on the anniversary date of the grant, and they expire 10 years from the original grant date. As of September 30, 2012, the total unrecognized compensation expense was $3,645,000, and the related weighted-average period over which it is expected to be recognized is 1.7 years. Following is a summary of the activity of the Company’s SARs program for the nine-month period ended September 30, 2012:

			Weighted-		Average	Aggregate
			Average		Remaining	Intrinsic
			Exercise		Contractual	Value
	Shares		Price		Term Years	*(In thousands)*
Outstanding at December 31, 2011	332,586		$	26.87	7.42	$	3,166
Granted	83,968		$	36.92
Exercised	(49,344	)	$	24.64
Outstanding at September 30, 2012	367,210		$	29.47	7.39		4,590
Exercisable at September 30, 2012	219,679		$	25.83	6.33		3,545

Following is a summary of the activity of the non-vested SARs during the nine-month period ended September 30, 2012:

			Weighted-Average
	Shares		Grant Date Fair Value
Non-vested at December 31, 2011	144,321		$	29.35
Granted	83,968		$	36.92
Vested	(80,758	)	$	27.49
Non-vested at September 30, 2012	147,531		$	34.89

The Company uses the Black-Scholes pricing model to determine the fair value of the SARs at the date of grant. Following are the assumptions used to estimate the per-share fair value of SARs granted:

	Nine Months Ended
	September 30,
	2012		2011
Risk-free interest rate	1.38	%	2.70	%
Expected life	7 yrs.		7 yrs.
Expected volatility	29.39	%	27.86	%
Expected dividend yield	1.84	%	1.77	%

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 rights using average monthly closing market prices of the Company’s stock as reported on The Nasdaq Global Market. The expected dividend yield is based on the Company’s current rate of annual dividends.

Compensation and Retirement Disclosure [Abstract]

Pension and Other Postretirement Benefits Disclosure [Text Block]

Note 9 – Defined Pension Plans

The Company has a noncontributory defined benefit pension 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. 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)*	2012			2011
Service cost – benefits earned during the year	$	2,986		$	2,073
Interest cost on projected benefit obligation		2,588			2,423
Expected return on plan assets		(3,967	)		(3,314	)
Net amortization and deferral		1,504			603
Net periodic pension cost	$	3,111		$	1,785

Pension costs recorded to expense were $1,011,000 and $415,000 for the three-month periods ended September 30, 2012 and 2011, respectively, and totaled $2,341,000 and $1,347,000 for the nine-month periods ended September 30, 2012 and 2011, respectively. The Company made a contribution of $750,000 to the plan during the three-month period ended September 30, 2012, for a total of $2,250,000 for the nine-month period ending September 30, 2012, and expects to contribute at least an additional $750,000 in 2012.

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 2011 and an estimate for 2012:

	Estimated		Actual
*(In thousands)*	2012		2011
Service cost – benefits earned during the year	$	134	$	89
Interest cost on projected benefit obligation		329		295
Net amortization		422		250
Net periodic pension cost	$	885	$	634

Investments, Debt and Equity Securities [Abstract]

Investments in Debt and Marketable Equity Securities (and Certain Trading Assets) Disclosure [Text Block]

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 falls into the Level 2 category. The amortized cost, gross unrealized gains, gross unrealized losses and fair value of investment securities are summarized as follows:

	September 30, 2012
			Gross		Gross
	Amortized		Unrealized		Unrealized
*(In thousands)*	Cost		Gains		Losses		Fair Value

The fair values of securities with unrealized losses are as follows:

Total	$	4,362	$	20	$	—	$	—	$	4,362	$	20

There were 23 securities (none greater than 12 months) in an unrealized loss position as of September 30, 2012. There were seven securities (none greater than 12 months) in an unrealized loss position as of December 31, 2011. 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 the Company has the ability and intent to hold these securities until maturity.

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.

	September 30, 2012
*(In thousands)*	Amortized Cost		Fair Value
Due in 1 year or less	$	18,898	$	19,036
Due after 1 year through 5 years		62,453		66,994
Due after 5 years through 10 years		180,082		190,378
Due after 10 years		85,304		91,111
Total	$	346,737	$	367,519

Proceeds from sales of investment securities classified as available for sale were $3,485,000 and $0 for the three months ended September 30, 2012 and 2011, respectively, and were $33,234,000 and $5,405,000 for the nine months ended September 30, 2012 and 2011, respectively. Gross realized gains were $267,000 and $0 for the three months ended September 30, 2012 and 2011, respectively, and were $2,401,000 and $48,000 for the nine months ended September 30, 2012 and 2011, respectively. There was one security for $3,250,000 pledged to secure public deposits and for other purposes at September 30, 2012.

Fair Value Disclosures [Abstract]

Fair Value Disclosures [Text Block]

Note 12 – Fair Value of Financial Instruments

Following is a summary of the carrying amounts and fair values of the Company’s financial instruments:

	September 30, 2012				December 31, 2011
	Carrying				Carrying
*(In thousands)*	Amount		Fair Value		Amount		Fair Value
Balance sheet assets:
Cash and cash equivalents	$	219,806	$	219,806	$	235,962	$	235,962
Investment securities		367,519		367,519		310,612		310,612
Loans, net		668,853		671,757		658,611		665,348
Accrued interest receivable		6,168		6,168		6,125		6,125
Total	$	1,262,346	$	1,265,250	$	1,211,310	$	1,218,047
Balance sheet liabilities:
Deposits	$	548,334	$	548,837	$	548,368	$	548,985
Accounts and drafts payable		648,944		648,944		595,201		595,201

Total	$	1,197,420	$	1,197,923	$	1,143,728	$	1,144,345

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 Other Short-term Instruments – For cash and cash equivalents, accrued interest receivable, accounts and drafts payable and accrued interest payable, the carrying amount is a reasonable estimate of fair value because of the demand nature or short maturities of these instruments.

Investment Securities – The fair value is measured using Level 2 valuations.

Loans – The fair value of loans is estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities.

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. 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.

There were no transfers between Levels 1 and 2 of the fair value hierarchy for the nine months ended September 30, 2012 and 2011. No financial instruments are measured using Level 3 inputs for the Nine Months Ended September 30, 2012 and 2011.

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.
