Purchase and Assumption

Purchase and Assumption

PURCHASE AND ASSUMPTION

Effective February 10, 2012, First Merchants Bank, National Association (the “Bank”) assumed substantially all of the deposits and certain other liabilities and acquired certain assets of SCB Bank, a federal savings bank headquartered in Shelbyville, Indiana, from the Federal Deposit Insurance Corporation (“FDIC”), as receiver for SCB Bank (the “Acquisition”), pursuant to the terms of the Purchase and Assumption Agreement – Modified Whole Bank; All Deposits (the “Agreement”), entered into by the Bank, the FDIC as receiver of SCB Bank and the FDIC.

Under the terms of the Agreement, the Bank acquired $147.7 million in assets, including approximately $11.9 million of cash and cash equivalents, $18.9 million of marketable securities, $1.8 million in Federal Home Loan Bank stock, $113.0 million in loans and $2.1 million of premises and other assets. The Bank assumed approximately $135.7 million of liabilities, including approximately $125.9 million in customer deposits, $9.6 million of other borrowed money and $402,000 in other liabilities. These balances are book balances and do not reflect the fair value adjustments which are shown on the following table. The acquisition did not include any loss sharing agreement with the FDIC.

The bid accepted by the FDIC included no deposit premium. The assets were acquired at a discount of $29.0 million from book value. The FDIC made a payment of $17.2 million to the Bank upon the final closing date balance sheet for SCB Bank that reflected the difference between the purchase price of the assets acquired and the value of the liabilities assumed.

The Bank engaged in this transaction with the expectation that it would be immediately accretive and add a new market area with a demographic profile consistent with many of the current Indiana markets served by the Bank.

The transaction was accounted for under the acquisition method of accounting in accordance with the Business Combination topic of the FASB Accounting Standards Codification (“ASC 310-20 and 310-30”). The statement of net assets and liabilities acquired as of February 10, 2012, are presented below. The assets and liabilities of SCB were recorded at the respective acquisition date provisional fair values, and identifiable intangible assets were recorded at provisional fair value.



Assets			Liabilities
Cash and due from banks ⁽¹⁾	$	29,113	Deposits:
Investment securities, available for sale	18,896		Non-interest bearing	$	13,715
Federal Home Loan Bank stock	1,761		NOW accounts	14,746
Loans:			Savings and money market	25,843
Commercial	51,042		Certificate of deposit	71,605
Residential mortgage	11,181		Total Deposits	125,909
Installment	31,570
Total Loans	93,793		Federal Home Loan Bank advances	10,286
			Other liabilities	804
Premises	1,516		Total Liabilities Assumed	$	136,999
Core deposit intangible	484
Other assets	560		Net Gain on Acquisition	$	9,124
Total Assets Purchased	$	146,123


(1)	Includes $17,200,000 cash received from the FDIC.

In many cases, the fair values of assets acquired and liabilities assumed were determined by estimating cash flows expected to result from those assets and liabilities and discounting them at appropriate market rates. The most significant category of assets for which this procedure was used was acquired loans. The Bank acquired the $113.0 million loan portfolio at a fair value discount of $19.2 million. The performing portion of the portfolio, $86.3 million, had an estimated fair value of $76.5 million. The excess of expected cash flows above the fair value of the performing portion of loans will be accreted to interest income over the remaining lives of the loans in accordance with ASC 310-20. Discounts or premiums on term loans are accounted for under an effective yield method. Prepayments on term loans are accounted for in the effective yield calculation. Discounts or premiums on lines of credit are treated in a straight line method over the term of the lines of credit.

Certain loans for which specific credit-related deterioration has occurred since origination are recorded at fair value which is derived from calculating the present value of the amounts expected to be collected. Income recognition on these loans is based on reasonable expectation about the timing and amount of cash flows to be collected. Some of the acquired loans deemed impaired and considered collateral dependent, with the timing of a sale of loan collateral indeterminate, remain on non-accrual status and have little to no accretable yield.

In accordance with ASC 310-30 (formerly Statement of Position (“SOP”) 03-3 as of February 10, 2012, loans acquired during 2012 for which it was probable at acquisition that all contractually required payments would not be collected are as follows:



Preliminary estimate of contractually required principal and interest at acquisition	$	31,143
Preliminary estimate of contractual cash flows not expected to be collected (nonaccretable differences)	9,688
Preliminary estimate of expected cash flows at acquisition	21,455
Preliminary estimate of interest component of expected cash flows (accretable discount)	4,152
Preliminary estimate of fair value of acquired loans accounted for under ASC 310-30	$	17,303

Pro-forma statements were determined to be impracticable due to the nature of the transaction as certain assets were not purchased.

- Definition

The entire disclosure for a business combination (or series of individually immaterial business combinations) completed during the period, including background, timing, and recognized assets and liabilities. The disclosure may include leverage buyout transactions (as applicable).

Percent of the Corporation's available for sale and held to maturity portfolio	4.4		%	1.9		%

The Corporation’s management has evaluated all securities with unrealized losses for other-than-temporary impairment ("OTTI") as of March 31, 2013. The evaluations are based on the nature of the securities, the extent and duration of the loss and the intent and ability of the Corporation to hold these securities either to maturity or through the expected recovery period.

The current unrealized losses are primarily concentrated within trust preferred securities held by the Corporation. Such investments have an amortized cost of $6.1 million and a fair value of $336,000, which is less than 1 percent of the Corporation’s entire investment portfolio. On all but one small pool investment, the Corporation utilized Moody’s to determine their fair value.

In determining the fair value of the trust preferred securities, the Corporation utilizes a third party for portfolio accounting services, including market value input. The Corporation has obtained an understanding of what inputs are being used by the vendor in pricing the portfolio and how the vendor was classifying these securities based upon these inputs. From these discussions, the Corporation’s management is comfortable that the classifications are proper. The Corporation has gained trust in the data for two reasons: (a) independent spot testing of the data is conducted by the Corporation through obtaining market quotes from various brokers on a periodic basis and (b) actual gains or loss resulting from the sale of certain securities has proven the data to be accurate over time.

Discount rates used in the OTTI cash flow analysis on these variable rate securities were those margins in effect at the inception of the security added to the appropriate three-month LIBOR spot rate obtained from the forward LIBOR curve used to project future principal and interest payments. These spreads ranged from .85 percent to 1.57 percent spread over LIBOR.

Management believes the declines in fair value for these securities are temporary. Should the impairment of any of these securities become other than temporary, the cost basis of the investment will be reduced and the resulting loss recognized in net income in the period the OTTI is identified.

U.S. Government-Sponsored Mortgage-Backed Securities

The unrealized losses on the Corporation’s investment in U.S. Government-sponsored mortgage-backed securities were a result of changes in interest rates. The Corporation expects to recover the amortized cost basis over the term of the securities as the decline in market value is attributable to changes in interest rates and not credit quality. The Corporation does not intend to sell the investment and it is not more likely than not that the Corporation will be required to sell the investment before recovery of its new, lower amortized cost basis, which may be maturity. The Corporation does not consider the investment securities to be other-than-temporarily impaired at March 31, 2013.

State and Municipal

The unrealized losses on the Corporation’s investments in securities of state and political subdivisions were caused by changes in interest rates. The contractual terms of those investments do not permit the issuer to settle the securities at a price less than the amortized cost basis of the investments. The Corporation does not intend to sell the investment and it is not more likely than not that the Corporation will be required to sell the investment before recovery of its new, lower amortized cost basis, which may be maturity. The Corporation does not consider the investment securities to be other-than-temporarily impaired at March 31, 2013.

Corporate Obligations

The Corporation’s unrealized losses on Corporate Obligations were due to the decline in value related to the pooled trust preferred securities, and is attributable to temporary illiquidity and the financial crisis affecting these markets, coupled with the potential credit loss resulting from the adverse change in expected cash flows. Due to the illiquidity in the market, it is unlikely that the Corporation would be able to recover its investment in these securities if the Corporation sold the securities at this time. Management has analyzed the cash flow characteristics of the securities and this analysis included utilizing the most recent trustee reports and any other relevant market information, including announcements of deferrals or defaults of trust preferred securities. The Corporation compared expected discounted cash flows, based on performance indicators of the underlying assets in the security, to the carrying value of the investment to determine if OTTI existed. The Corporation does not intend to sell the investment, and it is not more likely than not that the Corporation will be required to sell the investment before recovery of its new, lower amortized cost basis, which may be maturity. The Corporation does not consider the remainder of the investment securities, which are classified as Level 3 inputs in the fair value hierarchy, to be other-than-temporarily impaired at March 31, 2013.

Credit Losses Recognized on Investments

Certain debt securities have experienced fair value deterioration due to credit losses and other market factors. The following table provides information about debt securities for which only a credit loss was recognized in income and other losses were recorded in other comprehensive income.

Loans and Allowance

LOANS AND ALLOWANCE

The Corporation’s primary lending focus is small business and middle market commercial, residential real estate, auto and small consumer lending, which results in portfolio diversification. The following tables show the composition in the loan portfolio, loan grades and the allowance for loan losses excluding loans held for sale. Residential real estate loans held for sale at March 31, 2013, and December 31, 2012, were $26,555,000 and $22,300,000, respectively.

The following table shows the composition of the Corporation’s loan portfolio by loan class for the periods indicated:



	March 31, 2013			December 31, 2012
Loans:
Commercial and industrial loans	$	637,952		$	622,579
Agricultural production financing and other loans to farmers	104,284			112,527
Real estate loans:
Construction	75,877			98,639
Commercial and farmland	1,280,611			1,266,682

Lease financing receivables, net of unearned income	2,013			2,590
Other loans	36,095			46,501
Loans	2,879,542			2,902,209
Allowance for loan losses	(68,537		)	(69,366		)
Net Loans	$	2,811,005		$	2,832,843

The Corporation maintains an allowance for loan losses to cover probable credit losses identified during its loan review process. The allowance is increased by the provision for loan losses and decreased by charge offs less recoveries. All charge offs are approved by the Bank’s senior loan officers or loan committees, depending on the amount of the charge off. The Bank charges off a loan when a determination is made that all or a portion of the loan is uncollectible. The allowance for loan losses is maintained through the provision for loan losses, which is a charge against earnings.

The amount provided for loan losses in a given period may be greater than or less than net loan losses experienced during the period, and is based on management’s judgment as to the appropriate level of the allowance for loan losses. The determination of the provision amount in a given period is based on management’s ongoing review and evaluation of the loan portfolio, including an internally administered loan "watch" list and independent loan reviews. The evaluation takes into consideration identified credit problems, the possibility of losses inherent in the loan portfolio that are not specifically identified and management’s judgment as to the impact of current economic conditions on the portfolio.

Management believes that the allowance for loan losses is adequate to cover probable losses inherent in the loan portfolio at March 31, 2013. The process for determining the adequacy of the allowance for loan losses is critical to the Corporation’s financial results. It requires management to make difficult, subjective and complex judgments, to estimate the effect of uncertain matters. The allowance for loan losses considers current factors, including economic conditions and ongoing internal and external examinations, and will increase or decrease as deemed necessary to ensure the allowance remains adequate. In addition, the allowance as a percentage of charge offs and nonperforming loans will change at different points in time based on credit performance, loan mix and collateral values.

The historical loss allocation for loans not deemed impaired according to ASC 310 is the product of the volume of loans within the non-impaired criticized and non-criticized risk grade classifications, each segmented by call code, and the historical loss factor for each respective classification and call code segment. The historical loss factors are based upon actual loss experience within each risk and call code classification. The historical look back period for non-criticized loans looks to the most recent rolling-four-quarter average and aligns with the look back period for non-impaired criticized loans. Each of the rolling four quarter periods used to obtain the average, include all charge offs for the previous twelve-month period, therefore the historical look back period includes seven quarters. The resulting allocation is reflective of current conditions. Criticized loans are grouped based on the risk grade assigned to the loan. Loans with a special mention grade are assigned a loss factor, and loans with a classified grade but not impaired are assigned a separate loss factor. The loss factor computation for this allocation includes a segmented historical loss migration analysis of criticized risk grades to charge off.

In addition to the specific reserves and historical loss components of the allowance, consideration is given to various environmental factors to help ensure that losses inherent in the portfolio are reflected in the allowance for loan losses. The environmental component adjusts the historical loss allocations for commercial and consumer loans to reflect relevant current conditions that, in management's opinion, have an impact on loss recognition. Environmental factors that management reviews in the analysis include: national and local economic trends and conditions; trends in growth in the loan portfolio and growth in higher risk areas; levels of, and trends in, delinquencies and non-accruals; experience and depth of lending management and staff; adequacy of, and adherence to, lending policies and procedures including those for underwriting; industry concentrations of credit; and adequacy of risk identification systems and controls through the internal loan review and internal audit processes.

The risk characteristics of the Corporation’s material portfolio segments are as follows:

Commercial

Commercial loans are primarily based on the identified cash flows of the borrower and secondarily on the underlying collateral provided by the borrower. The cash flows of borrowers, however, may not be as expected and the collateral securing these loans may fluctuate in value. Most commercial loans are secured by the assets being financed or other business assets such as accounts receivable or inventory and may incorporate a personal guarantee; however, some short-term loans may be made on an unsecured basis. In the case of loans secured by accounts receivable, the availability of funds for the repayment of these loans may be substantially dependent on the ability of the borrower to collect amounts due from its customers.

Commercial real estate

These loans are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Commercial real estate lending typically involves higher loan principal amounts and the repayment of these loans is generally dependent on the successful operation of the property securing the loan or the business conducted on the property securing the loan. Commercial real estate loans may be more adversely affected by conditions in the real estate markets or in the general economy. Management monitors and evaluates commercial real estate loans based on collateral and risk grade criteria. In addition, management tracks the level of owner-occupied commercial real estate loans versus non-owner occupied loans.

Residential and Consumer

With respect to residential loans that are secured by 1-4 family residences and are generally owner occupied, the Corporation generally establishes a maximum loan-to-value ratio and requires private mortgage insurance if that ratio is exceeded. Home equity loans are typically secured by a subordinate interest in 1-4 family residences, and consumer loans are secured by consumer assets such as automobiles or recreational vehicles. Some consumer loans are unsecured such as small installment loans and certain lines of credit. Repayment of these loans is primarily dependent on the personal income and credit rating of the borrowers, which can be impacted by economic conditions in their market areas such as unemployment levels. Repayment can also be impacted by changes in property values on residential properties. Risk is mitigated by the fact that the loans are of smaller individual amounts and spread over a large number of borrowers.

The following tables summarize changes in the allowance for loan losses by loan segment for the three months ended March 31, 2013, and March 31, 2012:

Loans	$	781,607	$	1,365,321	$	75,748	$	676,943	$	2,590	$	2,902,209

Loans are reclassified to a non-accruing status when, in management’s judgment, the collateral value and financial condition of the borrower do not justify accruing interest. Interest previously recorded, but not deemed collectible, is reversed and charged against current income. Payments subsequently received on non-accrual loans are applied to principal. A loan is returned to accrual status when principal and interest are no longer past due and collectability is probable, typically after a minimum of six consecutive months of performance. Payments received on impaired accruing or delinquent loans are applied to interest income as accrued.

The following table summarizes the Corporation’s non-accrual loans by loan class at the periods indicated:



	March 31, 2013		December 31, 2012
Commercial and industrial	$	9,462	$	12,195
Agriculture Production financing and other loans to farmers	86
Real Estate Loans:
Construction	3,786		4,814
Commercial and farmland	19,303		22,612
Residential	11,856		11,476
Home Equity	2,268		1,997
Lease financing receivables, net of unearned income			301
Other Loans			4
Total	$	46,761	$	53,399

Commercial impaired loans include all non-accrual loans, loans accounted for under ASC 310-30 and renegotiated loans, as well as substandard, doubtful and loss grade loans that were still accruing but deemed impaired according to guidance set forth in ASC 310. Also included in impaired loans are accruing loans that are contractually past due 90 days or more. A loan is deemed impaired when, based on current information or events, it is probable that all amounts due of principal and interest according to the contractual terms of the loan agreement will not be collected.

Allowable methods for determining the amount of impairment include estimating fair value using the fair value of the collateral for collateral dependent loans. If the impaired loan is identified as collateral dependent, then the fair value method of measuring the amount of impairment is utilized. This method requires obtaining a current independent appraisal of the collateral and applying a discount factor to the value. The fair value of real estate is generally based on appraisals by qualified licensed appraisers. The appraisers typically determine the value of the real estate by utilizing an income or market valuation approach. If an appraisal is not available, the fair value may be determined by using a cash flow analysis. Fair value on other collateral such as business assets is typically ascertained by assessing, either singularly or some combination of, asset appraisals, accounts receivable aging reports, inventory listings and or customer financial statements. Both appraised values and values based on borrower’s financial information are discounted as considered appropriate based on age and quality of the information and current market conditions.

As part of the ongoing monitoring of the credit quality of the Corporation's loan portfolio, management tracks certain credit quality indicators including trends related to: (i) the level of criticized commercial loans, (ii) net charge offs, (iii) non-performing loans and (iv) the general national and local economic conditions.

The Corporation utilizes a risk grading of pass, special mention, substandard, doubtful and loss to assess the overall credit quality of large commercial loans. All large commercial credit grades are reviewed at a minimum of once a year for pass grade loans. Loans with grades below pass are reviewed more frequently depending on the grade. A description of the general characteristics of these grades is as follows:


•	Pass - Loans that are considered to be of acceptable credit quality.

•

Special Mention - Loans which possess some credit deficiency or potential weakness, which deserves close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the Corporation's credit position at some future date. Special mention assets are not adversely classified and do not expose the Corporation to sufficient risk to warrant adverse classification. The key distinctions of this category's classification are that it is indicative of an unwarranted level of risk; and weaknesses are considered “potential”, not “defined”, impairments to the primary source of repayment. Examples include businesses that may be suffering from inadequate management, loss of key personnel or significant customer or litigation.

•

Substandard - A substandard loan is inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Assets so classified have a well-defined weakness that jeopardizes the liquidation of the debt. They are characterized by the distinct possibility that the Corporation will sustain some loss if the deficiencies are not corrected. Other characteristics may include:



	o	the likelihood that a loan will be paid from the primary source of repayment is uncertain or financial deterioration is underway and very close attention is warranted to ensure that the loan is collected without loss,



	o	the primary source of repayment is gone, and the Corporation is forced to rely on a secondary source of repayment, such as collateral liquidation or guarantees,



	o	loans have a distinct possibility that the Corporation will sustain some loss if deficiencies are not corrected,



	o	unusual courses of action are needed to maintain a high probability of repayment,



	o	the borrower is not generating enough cash flow to repay loan principal; however, it continues to make interest payments,



	o	the Corporation is forced into a subordinated or unsecured position due to flaws in documentation,



	o	loans have been restructured so that payment schedules, terms and collateral represent concessions to the borrower when compared to the normal loan terms,



	o	the Corporation is seriously contemplating foreclosure or legal action due to the apparent deterioration of the loan, and



	o	there is significant deterioration in market conditions to which the borrower is highly vulnerable.

•

Doubtful - Loans that have all of the weaknesses of those classified as Substandard. However, based on currently existing facts, conditions and values, these weaknesses make full collection of principal highly questionable and improbable. Other credit characteristics may include the primary source of repayment is gone or there is considerable doubt as to the quality of the secondary sources of repayment. The possibility of loss is high, but because of certain important pending factors that may strengthen the loan, loss classification is deferred until the exact status of repayment is known.


•	Loss – Loans that are considered uncollectible and of such little value that continuing to carry them as an asset is not warranted. Loans will be classified as Loss when it is neither practical not desirable to defer writing off or reserving all or a portion of a basically worthless asset, even though partial recovery may be possible at some time in the future.

The following tables summarize the credit quality of the Corporation’s loan portfolio, by loan class at the periods indicated. Consumer non-performing loans include accruing consumer loans 90 plus days delinquent and consumer non-accrual loans. The entire balance of a loan is considered delinquent if the minimum payment contractually required to be made is not received by the specified date.

See the information regarding the analysis of loan loss experience in the "LOAN QUALITY/PROVISION FOR LOAN LOSSES" section of Management’s Discussion and Analysis of Financial Condition and Results of Operations included as ITEM 2 of this Form 10-Q.

Due to challenging economic conditions, borrowers of all types have experienced declines in income and cash flow. As a result, borrowers are occasionally seeking to reduce contractual cash outlays including debt payments. Concurrently, in an effort to preserve and protect its earning assets, specifically troubled loans, the Corporation is working to maintain its relationship with certain customers who are experiencing financial difficulty by contractually modifying the borrower's debt agreement with the Corporation. In certain loan restructuring situations, the Corporation may grant a concession to a debtor experiencing financial difficulty, resulting in a trouble debt restructuring. A concession is deemed to be granted when, as a result of the restructuring, the Corporation does not expect to collect all amounts due, including interest accrued at the original contract rate. If the payment of principal at original maturity is primarily dependent on the value of collateral, the current value of the collateral is considered in determining whether the principal will be paid.

The following tables summarize troubled debt restructurings that occurred during the periods indicated:



	Three Months Ended March 31, 2013
	Pre-Modification Recorded Balance		Post-Modification Recorded Balance		Number of Loans
Commercial and industrial	$	96	$	96	3
Real Estate Loans:

Commercial and Industrial Loans account for 50 percent of the troubled debt restructured loans made in the three months ended March 31, 2013. Five troubled debt restructured loans made during the three months ended March 31, 2013 are in non accrual status.

The following tables summarize troubled debt restructures that occurred during the twelve months ended March 31, 2013, and March 31, 2012, that subsequently defaulted during the period indicated:



	Three Months Ended March 31, 2013
	Number of Loans	Recorded Balance
Commercial and Industrial	1	$	5
Real Estate Loans:

	Number of Loans	Recorded Balance
Real Estate Loans:
Commercial and farmland	1	$	717
Residential	3	217
Total	4	$	934

For potential consumer loan restructures, impairment evaluation occurs prior to modification. Any subsequent impairment is typically addressed through the charge off process, or may be addressed through a specific reserve. Consumer troubled debt restructurings are generally included in the general historical allowance for loan loss at the post modification balance. Consumer non-accrual and delinquent troubled debt restructurings are also considered in the calculation of the non-accrual and delinquency trend environmental allowance allocation. Commercial troubled debt restructured loans risk graded special mention, substandard, doubtful and loss are individually evaluated for impairment under ASC 310. Any resulting specific reserves are included in the allowance for loan losses. Commercial 30 - 89 day delinquent troubled debt restructurings are included in the calculation of the delinquency trend environmental allowance allocation. All commercial non-impaired loans, including non-accrual and 90+ day delinquents, are included in the ASC 450 loss migration analysis.

Accounting for Certain Loans Acquired in a Purchase (Notes)

3 Months Ended

Receivables [Abstract]

Accounting for Certain Loans Acquired in a Purchase

ACCOUNTING FOR CERTAIN LOANS ACQUIRED IN A PURCHASE

The Bank acquired loans in a purchase during the year ended December 31, 2012. At acquisition, the purchased loans evidenced deterioration of credit quality since origination and it was probable, at acquisition, that all contractually required payments would not be collected.

Loans purchased with evidence of credit deterioration since origination and for which it is probable that all contractually required payments will not be collected are considered to be credit impaired. Evidence of credit quality deterioration as of the purchase date may include information

such as past-due and nonaccrual status, borrower credit scores and recent loan to value percentages. Purchased credit-impaired loans are accounted for under the accounting guidance for loans and debt securities acquired with deteriorated credit quality (ASC 310-30) and initially measured at fair value, which includes estimated future credit losses expected to be incurred over the life of the loan. Accordingly, an allowance for credit losses related to these loans is not carried over and recorded at the acquisition date. Management estimated the cash flows expected to be collected at acquisition, which incorporated the estimate of current key assumptions, such as default rates, severity and prepayment speeds.

The following table includes the carrying amount of these loans, which are included in the balance sheet amounts of loans receivable at March 31, 2013 and December 31, 2012.



	March 31, 2013		December 31, 2012
Commercial and industrial loans	$	6,337	$	8,542

Individuals' loans for household and other personal expenditures	570		691
Total	$	58,999	$	65,600

Accretable yield, or income expected to be collected, is as follows:



	Three Months Ended March 31, 2013
Beginning balance, Dec 31, 2012	$	5,142
Accretions	(771		)
Ending balance, March 31, 2013	$	4,371

Beginning balance, February 10, 2012	$	9,774
Accretions
Ending balance, March 31, 2012	$	9,774

- Definition

The entire disclosure for certain contractual rights to receive money on demand or on fixed or determinable dates with evidence of deterioration of credit quality since origination that were acquired by completion of a transfer for which it is probable, at acquisition, that the investor will be unable to collect all contractually required payments receivable.

Derivative Financial Instruments

3 Months Ended

Mar. 31, 2013

Uncategorized [Abstract]

Derivative Financial Instruments

DERIVATIVE FINANCIAL INSTRUMENTS

Risk Management Objective of Using Derivatives

The Corporation is exposed to certain risks arising from both its business operations and economic conditions. The Corporation principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Corporation manages economic risks, including interest rate, liquidity, and credit risk, primarily by managing the amount, sources, and duration of its assets and liabilities and through the use of derivative financial instruments. Specifically, the Corporation enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Corporation’s derivative financial instruments are used to manage differences in the amount, timing, and duration of the Corporation’s known or expected cash payments principally related to certain variable-rate liabilities. The Corporation also has derivatives that are a result of a service the Corporation provides to certain qualifying customers, and, therefore, are not used to manage interest rate risk in the Corporation’s assets or liabilities. The Corporation manages a matched book with respect to its derivative instruments offered as a part of this service to its customers in order to minimize its net risk exposure resulting from such transactions.

Cash Flow Hedges of Interest Rate Risk

The Corporation’s objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish these objectives, the Corporation primarily uses interest rate swaps and interest rate caps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the payment of fixed amounts to a counterparty in exchange for the Corporation receiving variable payments over the life of the agreements without exchange of the underlying notional amount. Interest rate caps designated as cash flow hedges involve the receipt of variable amounts from a counterparty if interest rates rise above the strike rate on the contract in exchange for an up-front premium. As of March 31, 2013 and 2012, the Corporation had two interest rate swaps with a notional amount of $26.0 million and one interest rate cap with a notional amount of $13.0 million that were designated as cash flow hedges.

The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive income and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. During 2013, such derivatives were used to hedge the variable cash outflows (LIBOR-based) associated with existing trust preferred securities when the outflows converted from a fixed rate to variable rate in September of 2012. The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings. During the three months ended March 31, 2013, and 2012, the Corporation did not recognize any ineffectiveness.

Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense as interest payments are made on the Corporation’s variable-rate liabilities. During the next twelve months, the Corporation expects to reclassify $767,000 from accumulated other comprehensive income to interest expense.

Non-designated Hedges

The Corporation does not use derivatives for trading or speculative purposes. Derivatives not designated as hedges are not speculative and result from a service the Corporation provides to certain customers. The Corporation executes interest rate swaps with commercial banking customers to facilitate their respective risk management strategies. Those interest rate swaps are simultaneously hedged by offsetting interest rate swaps that the Corporation executes with a third party, such that the Corporation minimizes its net risk exposure resulting from such transactions. As the interest rate swaps associated with this program do not meet the strict hedge accounting requirements, changes in the fair value of both the customer swaps and the offsetting swaps are recognized directly in earnings. As of March 31, 2013, the notional amount of customer-facing swaps was approximately $159,817,000. This amount is offset with third party counterparties, as described above.

The Corporation’s exposure to credit risk occurs because of nonperformance by its counterparties. The counterparties approved by the Corporation are usually financial institutions, which are well capitalized and have credit ratings through Moody’s and/or Standard & Poor’s, at or above investment grade. The Corporation’s control of such risk is through quarterly financial reviews, comparing mark-to-mark values with policy limitations, credit ratings and collateral pledging.

Credit-risk-related Contingent Features

The Corporation also has agreements with certain of its derivative counterparties that contain a provision where if the Corporation fails to maintain its status as a well or adequate capitalized institution, then the Corporation could be required to terminate or fully collateralize all outstanding derivative contracts.

The Corporation has agreements with certain of its derivative counterparties that contain a provision where if the Corporation defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, the Corporation could also be declared in default on its derivative obligations.

As of March 31, 2013, the termination value of derivatives in a net liability position related to these agreements was $8,510,000. As of March 31, 2013, the Corporation had minimum collateral posting thresholds with certain of its derivative counterparties and had posted collateral of $7,638,000. If the Corporation had breached any of these provisions at March 31, 2013, it could have been required to settle its obligations under the agreements at their termination value.

Disclosures About Fair Value of Assets and Liabilities

DISCLOSURES ABOUT FAIR VALUE OF ASSETS AND LIABILITIES

The Corporation used fair value measurements to record fair value adjustments, to certain assets, and liabilities and to determine fair value disclosures. The accounting guidance defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. ASC 820 applies only when other guidance requires or permits assets or liabilities to be measured at fair value; it does not expand the use of fair value in any new circumstances.

As defined in ASC 820, fair value is the price to sell an asset or transfer a liability in an orderly transaction between market participants. It represents an exit price at the measurement date. Market participants are buyers and sellers, who are independent, knowledgeable, and willing and able to transact in the principal (or most advantageous) market for the asset or liability being measured. Current market conditions, including imbalances between supply and demand, are considered in determining fair value. The Corporation values its assets and liabilities in the principal market where it sells the particular asset or transfers the liability with the greatest volume and level of activity. In the absence of a principal market, the valuation is based on the most advantageous market for the asset or liability (i.e., the market where the asset could be sold or the liability transferred at a price that maximizes the amount to be received for the asset or minimizes the amount to be paid to transfer the liability).

Valuation inputs refer to the assumptions market participants would use in pricing a given asset or liability. Inputs can be observable or unobservable. Observable inputs are those assumptions which market participants would use in pricing the particular asset or liability. These inputs are based on market data and are obtained from a source independent of the Corporation. Unobservable inputs are assumptions based on the Corporation’s own information or estimate of assumptions used by market participants in pricing the asset or liability. Unobservable inputs are based on the best and most current information available on the measurement date. All inputs, whether observable or unobservable, are ranked in accordance with a prescribed fair value hierarchy which gives the highest ranking to quoted prices (unadjusted) in active markets for identical assets or liabilities (Level 1) and the lowest ranking to unobservable inputs for which there is little or no market activity (Level 3). Fair values for assets or liabilities classified as Level 2 are based on one or a combination of the following factors: (i) quoted prices for similar assets; (ii) observable inputs for the asset or liability, such as interest rates or yield curves; or (iii) inputs derived principally from or corroborated by observable market data. The level in the fair value hierarchy within which the fair value measurement in its entirety falls is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The Corporation considers an input to be significant if it drives 10 percent or more of the total fair value of a particular asset or liability.

Recurring Measurements

The following table presents the fair value measurements of assets and liabilities recognized in the Consolidated Condensed Balance Sheets measured at fair value on a recurring basis and the level within the fair value hierarchy in which the fair value measurements fall at March 31, 2013, and December 31, 2012.



			Fair Value Measurements Using:
March 31, 2013	Fair Value		Quoted Prices in Active Markets for Identical Assets (Level 1)	Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)

			Fair Value Measurements Using:
December 31, 2012	Fair Value		Quoted Prices in Active Markets for Identical Assets (Level 1)	Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
Available for sale securities:
U.S. Government-sponsored agency securities	$	4,640		$	4,640

Interest rate swap asset	6,103			6,103
Interest rate cap	197			197
Interest rate swap liability	9,766			9,766

Following is a description of the valuation methodologies and inputs used for instruments measured at fair value on a recurring basis and recognized in the accompanying Consolidated Condensed Balance Sheets, as well as the general classification of such instruments pursuant to the valuation hierarchy. There have been no significant changes in the valuation techniques during the three months ended March 31, 2013.

Available for Sale Investment Securities

Where quoted, market prices are available in an active market and securities are classified within Level 1 of the valuation hierarchy. There are no securities classified within Level 1 of the hierarchy. If quoted market prices are not available, then fair values are estimated by using pricing models, quoted prices of securities with similar characteristics or discounted cash flows. Level 2 securities include agencies, mortgage backs, state and municipal, and equity securities. In certain cases where Level 1 or Level 2 inputs are not available, securities are classified within Level 3 of the hierarchy. Level 3 fair value, including corporate obligations, state and municipal and equity securities, was determined using a discounted cash flow model that incorporated market estimates of interest rates and volatility in markets that have not been active.

Third party vendors compile prices from various sources and may apply such techniques as matrix pricing to determine the value of identical or similar investment securities classified within Level 2. Matrix pricing is a mathematical technique widely used in the banking industry to value investment securities without relying exclusively on quoted prices for specific investment securities but rather relying on the investment securities’ relationship to other benchmark quoted investment securities. Any investment security not valued based upon the methods above are considered Level 3.

Pooled Trust Preferred Securities

Pooled trust preferred securities are classified as Level 3 inputs in the fair value hierarchy. These securities were rated A or better at inception, but at March 31, 2013, Moody’s ratings on these securities ranged from Ca to C. The issuers in these securities are primarily banks, but some of the pools do include a limited number of insurance companies. On a quarterly basis, the Corporation uses an other-than-temporary impairment (“OTTI”) evaluation process to compare the present value of expected cash flows to determine whether an adverse change in cash flows has occurred. The OTTI evaluation process considers the structure and term of the collateralized debt obligation (“CDO”), interest rates, principal balances of note classes and underlying issuers, the timing and amount of interest and principal payments of the underlying issuers, and the allocation of the payments to the note classes. The current estimate of expected cash flows is based on the most recent trustee reports and any other relevant market information including announcements of interest payment deferrals or defaults of underlying trust preferred securities. Assumptions used in the evaluation process include expected future default rates and prepayments as well as recovery assumptions on defaults and deferrals. In addition, the process is used to “stress” each CDO, or make assumptions more severe than expected activity, to determine the degree to which assumptions could deteriorate before the CDO could no longer fully support repayment of the Corporation’s note class. Upon completion of the March 31, 2013 quarterly evaluation process, the conclusion was no OTTI for the three months ending March 31, 2013.

Interest Rate Derivative Agreements

See information regarding the Corporation's interest rate derivative products in NOTE 6. DERIVATIVE FINANCIAL INSTRUMENTS, included within the Notes to Consolidated Condensed Financial Statements of this Form 10-Q.

The fair value of the interest rate swap and cap instruments were transferred from Level 3 to Level 2 as of March 31, 2012 due to the availability of additional valuation information. These instruments were valued using widely accepted valuation techniques including discounted cash flow analysis using observable inputs such as contractual terms and LIBOR-based rate curves.

Level 3 Reconciliation

The following is a reconciliation of the beginning and ending balances of recurring fair value measurements recognized in the Consolidated Condensed Balance Sheets using significant unobservable (Level 3) inputs for the three months ended March 31, 2013, and 2012.



	Three Months Ended March 31, 2013
	Available for Sale Securities			Interest Rate Swap Asset	Interest Rate Cap	Interest Rate Swap Liability
Balance at beginning of the period	$	18,328
Total realized and unrealized gains and losses:
Included in net income (loss)
Included in other comprehensive income	(176		)
Purchases, issuances and settlements
Transfers in/(out) of Level 3
Principal payments/additions	(474		)
Ending balance at March 31, 2013	$	17,678



	Three Months Ended March 31, 2012
	Available for Sale Securities			Interest Rate Swap Asset			Interest Rate Cap			Interest Rate Swap Liability
Balance at beginning of the period	$	20,838		$	5,241		$	424		$	(7,797	)
Total realized and unrealized gains and losses:
Included in net income (loss)				(860		)				863
Included in other comprehensive income	(523		)	481			(15		)
Purchases, issuances and settlements
Transfers in/(out) of Level 3				(4,862		)	(409		)	6,934
Principal payments	(437		)
Ending balance at March 31, 2012	$	19,878

There were no gains or losses for the period included in earnings that were attributable to the changes in unrealized gains or losses related to assets or liabilities held at March 31, 2013 or December 31, 2012.

Transfers Between Levels

Transfer between Levels 1, 2 and 3 and the reasons for those transfers are as follows:



	Three Months Ended March 31, 2012
	Quoted Prices in Active Markets for Identical Assets (Level 1)	Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)			Reason for Transfer
Transfers to/(from) Level:
Interest rate swap asset		$	4,862	$	(4,862	)	The interest rate swap and cap instruments were transferred from Level 3 to Level 2 as of March 31, 2012 due to the availability of additional valuation information. These instruments are valued using widely accepted valuation techniques including discounted cash flow analysis using observable inputs such as contractual terms and LIBOR-based rate curves.
Interest rate cap		409		(409		)
Interest rate swap liability		6,934		(6,934		)
		$	12,205	$	(12,205	)

Nonrecurring Measurements

The following table presents the fair value measurement of assets and liabilities measured at fair value on a nonrecurring basis and the level within the fair value hierarchy in which the fair value measurements fall at March 31, 2013, and December 31, 2012.



			Fair Value Measurements Using
March 31, 2013	Fair Value		Quoted Prices in Active Markets for Identical Assets (Level 1)	Significant Other Observable Inputs (Level 2)	Significant Unobservable Inputs (Level 3)
Impaired loans (collateral dependent)	$	11,096			$	11,096
Other real estate owned	$	4,411			$	4,411



			Fair Value Measurements Using
December 31, 2012	Fair Value		Quoted Prices in Active Markets for Identical Assets (Level 1)	Significant Other Observable Inputs (Level 2)	Significant Unobservable Inputs (Level 3)
Impaired loans (collateral dependent)	$	17,703			$	17,703
Other real estate owned	$	7,684			$	7,684

Following is a description of valuation methodologies used for instruments measured at fair value on a nonrecurring basis and recognized in the Consolidated Condensed Balance Sheets, as well as the general classification of such instruments pursuant to the valuation hierarchy.

Impaired Loans (collateral dependent)

Loans for which it is probable that the Corporation will not collect all principal and interest due according to contractual terms are measured for impairment. Allowable methods for determining the amount of impairment include estimating fair value of the collateral for collateral dependent loans. If the impaired loan is identified as collateral dependent, then the fair value method of measuring the amount of impairment is utilized. This method requires obtaining a current independent appraisal of the collateral and applying a discount factor to the value. A portion of the allowance for loan losses is allocated to impaired loans if the value of such loans is deemed to be less than the unpaid balance. If these allocations cause the allowance for loan losses to increase, such increase is reported as a component of the provision for loan losses. Loan losses are charged against the allowance when management believes the uncollectability of the loan is confirmed. During 2013, certain impaired loans were partially charged off or re-evaluated. Impaired loans that are collateral dependent are classified within Level 3 of the fair value hierarchy when impairment is determined using the fair value method.

Other Real Estate Owned

The fair value for impaired loans and other real estate owned is measured based on the value of the collateral securing those loans or real estate and is determined using several methods. The fair value of real estate is generally determined based on appraisals by qualified licensed appraisers. The appraisers typically determine the value of the real estate by utilizing an income or market valuation approach. If an appraisal is not available, the fair value may be determined by using a cash flow analysis. Fair value on other collateral such as business assets is typically ascertained by assessing, either singularly or some combination of, asset appraisals, accounts receivable aging reports, inventory listings and or customer financial statements. Both appraised values and values based on borrower’s financial information are discounted as considered appropriate based on age and quality of the information and current market conditions.

Unobservable (Level 3) Inputs

The following table presents quantitative information about unobservable inputs used in recurring and nonrecurring Level 3 fair value measurements, other than goodwill, at March 31, 2013.



	Fair Value		Valuation Technique	Unobservable Inputs	Range
State and municipal securities	$	17,307	Discounted cash flow	Maturity/Call date	1 month to 11 yrs
				Blend of US Muni BQ curve	A- to BBB-
				Discount rate	1% - 4%
Corporate obligations/Equity securities	$	371	Discounted cash flow	Risk free rate	3 month LIBOR
				plus Premium for illiquidity	plus 200bps
Impaired loans (collateral dependent)	$	11,096	Collateral based	Discount to reflect current market	0% - 50%
			measurements	conditions and ultimate collectability
Other real estate owned	$	4,411	Appraisals	Discount to reflect current market	0% - 20%
				conditions

Sensitivity of Significant Unobservable Inputs

The following is a discussion of the sensitivity of significant unobservable inputs, the interrelationships between those inputs and other unobservable inputs used in recurring fair value measurement and of how those inputs might magnify or mitigate the effect of changes in the unobservable inputs on the fair value measurement.

State and Municipal Securities

The significant unobservable inputs used in the fair value measurement of the Corporation’s state and municipal securities are premiums for unrated securities and marketability discounts. Significant increases or decreases in either of those inputs in isolation would result in a significantly lower or higher fair value measurement. Generally, changes in either of those inputs will not affect the other input.

Corporate Obligations/Equity Securities

The significant unobservable inputs used in the fair value measurement of the Corporation’s corporate obligations/equity securities are premiums for unrated securities and marketability discounts. Significant increases or decreases in either of those inputs in isolation would result in a significantly lower or higher fair value measurement. Generally, changes in either of those inputs will not affect the other input.

Fair Value of Financial Instruments

The following table presents estimated fair values of the Corporation’s financial instruments and the level within the fair value hierarchy in which the fair value measurements fall at March 31, 2013, and December 31, 2012.

The following methods were used to estimate the fair value of all other financial instruments recognized in the Consolidated Condensed Balance Sheets at amounts other than fair value.

Cash and due from banks: The fair value of cash and cash equivalents approximates carrying value.

Interest-bearing time deposits: The fair value of interest-bearing time deposits approximates carrying value.

Investment securities: Fair value is based on quoted market prices, if available. If a quoted market price is not available, fair value is estimated using quoted market prices for similar securities.

Mortgage Loans Held For Sale: The carrying amount approximates fair value due to the short duration between origination and date of sale.

Loans: The fair value for loans is estimated using discounted cash flow analysis, using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality. See Impaired Loans above.

Federal Reserve and Federal Home Loan Bank stock: The fair value of Federal Reserve Bank and Federal Home Loan Bank stock is based on the price which it may be resold to the Federal Reserve and Federal Home Loan Bank.

Derivative instruments: The fair value of the interest rate swaps reflects the estimated amounts that would have been received to terminate these contracts at the reporting date based upon pricing or valuation models applied to current market information. Interest rate caps are valued using the market standard methodology of discounting the future expected cash receipts that would occur if variable interest rates rose above the strike rate of the caps. The projected cash receipts on the caps are based on an expectation of future interest rates derived from observed market interest rate curves and volatilities.

Interest Receivable and Interest Payable: The fair value of interest receivables/payable approximates the carrying amount.

Deposits: The fair values of noninterest-bearing and interest-bearing demand accounts and savings deposits are equal to the amount payable on demand at the balance sheet date. The carrying amounts for variable rate, fixed-term certificates of deposit approximate their fair values at the balance sheet date. Fair values for fixed-rate certificates of deposit and other time deposits are estimated using a discounted cash flow calculation that applies interest rates currently being offered to a schedule of aggregated expected monthly maturities on such time deposits.

Federal funds purchased: The fair value of Federal Funds purchased approximates the carrying amount.

Borrowings: The fair value of borrowings is estimated using a discounted cash flow calculation, based on current rates for similar debt.

Share-Based Compensation

3 Months Ended

Mar. 31, 2013

Uncategorized [Abstract]

Share-Based Compensation

SHARE-BASED COMPENSATION

Stock options and restricted stock awards ("RSAs") have been issued to directors, officers and other management employees under the Corporation's 1999 Long-term Equity Incentive Plan and the 2009 Long-term Equity Incentive Plan. The stock options, which have a 10-year life, become 100 percent vested ranging from six months to two years and are fully exercisable when vested. Option exercise prices equal the Corporation's common stock closing price on NASDAQ on the date of grant. RSAs provide for the issuance of shares of the Corporation's common stock at no cost to the holder and generally vest after three years. The RSAs vest only if the employee is actively employed by the Corporation on the vesting date and, therefore, any unvested shares are forfeited. RSAs for employees retired from the Corporation continue to vest after retirement. Deferred stock units ("DSUs") can be credited to non-employee directors who have elected to defer payment of compensation under the Corporation's 2008 Equity Compensation Plan for Non-employee Directors. DSUs credited are equal to the restricted shares that the non-employee director would have received under the plan. As of March 31, 2013, there were no outstanding DSUs.

The Corporation’s 2009 Employee Stock Purchase Plan (“ESPP”) provides eligible employees of the Corporation and its subsidiaries an opportunity to purchase shares of common stock of the Corporation through quarterly offerings financed by payroll deductions. The price of the stock to be paid by the employees shall be equal to 85 percent of the average of the closing price of the Corporation’s common stock on each trading day during the offering period. However, in no event shall such purchase price be less than the lesser of an amount equal to 85 percent of the market price of the Corporation’s stock on the offering date or an amount equal to 85 percent of the market value on the date of purchase. Common stock purchases are made quarterly and are paid through advance payroll deductions up to a calendar year maximum of $25,000.

Compensation expense related to unvested share-based awards is recorded by recognizing the unamortized grant date fair value of these awards over the remaining service periods of those awards, with no change in historical reported fair values and earnings. Awards are valued at fair value in accordance with provisions of share-based compensation guidance and are recognized on a straight-line basis over the service periods of each award. To complete the exercise of vested stock options, RSA’s and ESPP options, the Corporation generally issues new shares from its authorized but unissued share pool. Share-based compensation for the three months ended March 31, 2013 and 2012 were $374,000 and $326,000 respectively. Share-based compensation has been recognized as a component of salaries and benefits expense in the accompanying CONSOLIDATED CONDENSED STATEMENTS OF INCOME.

The estimated fair value of the stock options granted during 2013 and in prior years was calculated using a Black Scholes option pricing model. The following summarizes the assumptions used in the 2013 Black Scholes model:



Risk-free interest rate	1.25	%
Expected price volatility	45.68	%
Dividend yield	2.96	%
Forfeiture rate	4.73	%
Weighted-average expected life, until exercise	7.3 years

The Black Scholes model incorporates assumptions to value share-based awards. The risk-free rate of interest, for periods equal to the expected life of the option, is based on a U.S. government instrument over a similar contractual term of the equity instrument. Expected price volatility is based on historical volatility of the Corporation’s common stock. In addition, the Corporation generally uses historical information to determine the dividend yield and weighted-average expected life of the options until exercise. Separate groups of employees that have similar historical exercise behavior with regard to option exercise timing and forfeiture rates are considered separately for valuation and attribution purposes.

Share-based compensation expense recognized in the CONSOLIDATED CONDENSED STATEMENTS OF INCOME is based on awards ultimately expected to vest and is reduced for estimated forfeitures. Share-based compensation guidance requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods, if actual forfeitures differ from those estimates. Pre-vesting forfeitures were estimated to be approximately five percent for the three months ended March 31, 2013, based on historical experience.

The following table summarizes the components of the Corporation's share-based compensation awards recorded as expense:



	Three Months Ended March 31,
	2013			2012
Stock and ESPP Options
Pre-tax compensation expense	$	38		$	46
Income tax benefit	(2		)
Stock and ESPP option expense, net of income taxes	$	36		$	46
Restricted Stock Awards
Pre-tax compensation expense	$	336		$	280
Income tax benefit	(117		)	(106		)
Restricted stock awards expense, net of income taxes	$	219		$	174
Total Share-Based Compensation:
Pre-tax compensation expense	$	374		$	326
Income tax benefit	(119		)	(106		)
Total share-based compensation expense, net of income taxes	$	255		$	220

As of March 31, 2013, unrecognized compensation expense related to stock options and RSAs totaling $94,000 and $3,071,000, respectively, is expected to be recognized over weighted-average periods of 1.14 and 1.86 years, respectively.

Stock option activity under the Corporation's stock option plans as of March 31, 2013 and changes during the three months ended March 31, 2013, were as follows:



	Number of Shares		Weighted-Average Exercise Price		Weighted Average Remaining Contractual Term (in Years)	Aggregate Intrinsic Value
Outstanding at January 1, 2013	906,636		$	21.58
Granted	9,000		$	15.32
Exercised	(2,250	)	$	6.99
Canceled	(8,471	)	$	24.69
Outstanding March 31, 2013	904,915		$	21.60	3.87	1,140,887
Vested and Expected to Vest at March 31, 2013	904,915		$	21.60	3.87	1,140,887
Exercisable at March 31, 2013	867,615		$	22.00	3.64	1,023,790

The weighted-average grant date fair value was $5.32 and $3.86 for stock options granted during the three months ended March 31, 2013 and 2012, respectively.

The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value (the difference between the Corporation's closing stock price on the last trading day of the first three months of 2013 and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their stock options on March 31, 2013. The amount of aggregate intrinsic value will change based on the fair market value of the Corporation's common stock. The aggregate intrinsic value of stock options exercised during the first three months of 2013 was $18,000. Cash receipts of stock options exercised during this same period were $16,000. There were no stock options exercised during the first three months of 2013.

The following table summarizes information on unvested RSAs outstanding as of March 31, 2013:



	Number of Shares		Weighted-Average Grant Date Fair Value
Unvested RSAs at January 1, 2013	401,375		$	9.29
Granted	109,118		$	14.74
Vested	(100,123	)	$	5.95
Forfeited	(200	)	$	11.38
Unvested RSAs at March 31, 2013	410,170		$	11.55

The grant date fair value of ESPP options was estimated at the beginning of the January 1, 2013 quarterly offering period of approximately $17,000. The ESPP options vested during the three months ending March 31, 2013, leaving no unrecognized compensation expense related to unvested ESPP options at March 31, 2013.

Net Income Per Share

3 Months Ended

Mar. 31, 2013

Earnings Per Share [Abstract]

Net Income Per Share

Basic net income per share is computed by dividing net income by the weighted-average shares outstanding during the reporting period. Diluted net income per share is computed by dividing net income by the combination of all dilutive common share equivalents, comprised of shares issuable under the Corporation’s share-based compensation plans, and the weighted-average shares outstanding during the reporting period.

Dilutive common share equivalents include the dilutive effect of in-the-money share-based awards, which are calculated based on the average share price for each period using the treasury stock method. Under the treasury stock method, the exercise price of share-based awards, the amount of compensation expense, if any, for future service that the Corporation has not yet recognized, and the amount of estimated tax benefits that would be recorded in additional paid-in capital when share-based awards are exercised, are assumed to be used to repurchase common stock in the current period.

The following table reconciles basic and diluted net income per share for the three months ended March 31, 2013 and 2012.



	Three Months Ended March 31,
	2013						2012
	Net Income			Weighted-Average Shares	Per Share Amount		Net Income			Weighted-Average Shares	Per Share Amount
Basic net income per share:	$	11,865					$	14,371
Less: Preferred Stock dividends and discount accretion	(857		)				(1,135		)
Net income available to common stockholders	11,008			28,716,987	$	0.38	13,236			28,582,616	$	0.46
Effect of dilutive stock options and warrants				254,251						172,097
Diluted net income per share:
Net income available to common stockholders	$	11,008		28,971,238	$	0.38	$	13,236		28,754,713	$	0.46

Stock options to purchase 698,718 and 967,987 shares for the three months ended March 31, 2013, and 2012, respectively, were not included in the earnings per share calculation because the exercise price exceeded the average market price.

Impact of Accounting Changes	IMPACT OF ACCOUNTING CHANGES ASU 2011-11 - Balance Sheet (Topic 210): Disclosures about Offsetting Assets and Liabilities. The ASU amends Topic 210 by requiring additional improved information to be disclosed regarding financial instruments and derivative instruments that are offset in accordance with the conditions under ASC 210-20-45 or ASC 810-10-45 or subject to an enforceable master netting arrangement or similar agreement. The amendments are effective for annual and interim reporting periods beginning on or after January 1, 2013. The disclosures required by the amendments were applied retrospectively for all comparative periods presented. The amendments did not have a material impact on the Corporation's Condensed Consolidated Financial Statements. ASU 2013-01- Balance Sheet (Topic 210): Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities. The ASU amends Update 2011-11 to clarify that the scope applies to derivatives, repurchase and reverse repurchase agreements, and securities borrowing and lending transactions that are either offset in accordance with Section 210-20-45 or Section 815-10-45 or subject to master netting or similar arrangements. Other types of financial assets and liabilities subject to master netting or similar arrangements are not subject to the disclosure requirements in Update 2011-11. The amendments are effective for fiscal years beginning on or after January 1, 2013, and interim periods within those annual periods. The amendments did not have a material impact on the Corporation's Condensed Consolidated Financial Statements. ASU 2013-02- Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. The ASU requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. The amendments are effective prospectively for reporting periods beginning after December 15, 2012. The disclosures required by the amendment were applied retrospectively for all comparative periods presented (See NOTE 8. ACCUMULATED OTHER COMPREHENSIVE INCOME).

- Definition

The entire disclosure of changes in accounting principles, including adoption of new accounting pronouncements, that describes the new methods, amount and effects on financial statement line items.
