Schedule of Changes in Level Three Assets and Liabilities Measured at Fair Value on a Recurring Basis

The following tables present the changes in Level 3 assets and liabilities measured at fair value on a recurring basis during the periods indicated:

Three months ended June 30,	2012		2011
(Dollars in thousands)	Securities Available for Sale (1)		Securities Available for Sale (1)		Derivative Assets / (Liabilities) (2)			Total

(Dollars in thousands)	Securities Available for Sale (1)			Securities Available for Sale (1)			Derivative Assets / (Liabilities) (2)			Total

Balance at end of period		$767			$934			($38	)		$896

(1) During the periods indicated, Level 3 securities available for sale were comprised of two pooled trust preferred debt securities, in the form of collateralized debt obligations.

(2) During the periods indicated, Level 3 derivative assets / liabilities consisted of forward loan commitments (interest rate lock commitments and commitments to sell fixed-rate residential mortgages). After evaluating forward loan commitments during the third quarter of 2011, it was determined that significant inputs and significant value drivers were observable in active markets, and the Corporation therefore reclassified these derivatives from out of Level 3 into Level 2.

(3) Losses included in earnings for Level 3 securities available for sale consisted of credit-related impairment losses on two Level 3 pooled trust preferred debt securities. No credit-related impairment losses were recognized during the three months endedJune 30, 2012 and 2011. Credit-related impairment losses of $209 thousand and $33 thousand were recognized during the six months ended June 30, 2012 and 2011, respectively. The losses included in earnings for Level 3 derivative assets and liabilities, which were comprised of forward loan commitments (interest rate lock commitments and commitments to sell fixed-rate residential mortgages), were included in net gains on loan sales and commissions on loans originated for others in the Consolidated Statements of Income.

Quantitative Information About Level 3 Assets Measured at Fair Value on a Recurring Basis

The following table presents additional quantitative information about assets measured at fair value on a recurring basis for which the Corporation has utilized Level 3 inputs to determine fair value.

(Dollars in thousands)	June 30, 2012
	Fair Value		Valuation Technique	Unobservable Input	Range of Inputs Utilized (Weighted Average)
Trust preferred securities:
Collateralized debt obligations		$767	Discounted Cash Flow	Discount Rate	17.50%
				Cumulative Default %	5.2% - 100% (27.1%)
				Loss Given Default %	85% - 100% (90.9%)

Given the low level of market activity for trust preferred securities in the form of collateralized debt obligations, the discount rate utilized in the fair value measurement was derived by analyzing current market yields for trust preferred securities of individual name issuers in the financial services industry. Adjustments were then made for credit and structural differences between these types of securities. There is an inverse correlation between the discount rate and the fair value measurement. When the discount rate increases, the fair value decreases.

Other significant unobservable inputs to the fair value measurement of collateralized debt obligations included prospective defaults and recoveries. The cumulative default percentage represents the lifetime defaults assumed, excluding currently defaulted collateral and including all performing and currently deferring collateral. As a result, the cumulative default percentage also reflects assumptions of the possibility of currently deferring collateral curing and becoming current. The loss given default percentage represents the percentage of current and projected defaults assumed to be lost. There is an inverse correlation between the cumulative default and loss given default percentages and the fair value measurement. When the default percentages increase, the fair value decreases.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

Items Recorded at Fair Value on a Nonrecurring Basis

Certain assets are measured at fair value on a nonrecurring basis in accordance with GAAP.  These adjustments to fair value usually result from the application of lower of cost or market accounting or write-downs of individual assets.  The valuation methodologies used to measure these fair value adjustments are described above.

The following table presents the carrying value of certain assets measured at fair value on a nonrecurring basis during the six months endedJune 30, 2012:

(Dollars in thousands)	Carrying Value at June 30, 2012
	Level 1		Level 2		Level 3		Total
Collateral dependent impaired loans		$—		$—		$2,792		$2,792
Property acquired through foreclosure or repossession	—		—		1,070		1,070
Total assets at fair value on a nonrecurring basis		$—		$—		$3,862		$3,862

Collateral dependent impaired loans with a carrying value of $2.8 million at June 30, 2012 were subject to nonrecurring fair value measurement during the six months endedJune 30, 2012.  As of June 30, 2012, the allowance for loan losses allocation on these loans amounted to $733 thousand.

During the six months endedJune 30, 2012, properties acquired through foreclosures or repossession with a fair value of $1.8 million were transferred from loans.  Prior to the transfer, the assets whose fair value less costs to sell was less than the carrying value were written down to fair value through a charge to the allowance for loan losses. For the three and six months endedJune 30, 2012, such valuation adjustments charged to the allowance for loan losses amounted to $268 thousand and $332 thousand, respectively.  Subsequent to foreclosures, valuations are updated periodically and assets may be marked down further, reflecting a new cost basis. Subsequent valuation adjustments charged to earnings totaled $52 thousand and $171 thousand for the three and six months endedJune 30, 2012, respectively.

The following table presents the carrying value of certain assets measured at fair value on a nonrecurring basis during the six months endedJune 30, 2011:

(Dollars in thousands)	Carrying Value at June 30, 2011
	Level 1		Level 2		Level 3		Total
Collateral dependent impaired loans		$—		$—		$3,292		$3,292
Property acquired through foreclosure or repossession	—		—		1,449		1,449
Total assets at fair value on a nonrecurring basis		$—		$—		$4,741		$4,741

Collateral dependent impaired loans with a carrying value of $3.3 million at June 30, 2011 were subject to nonrecurring fair value measurement during the six months endedJune 30, 2011.  As of June 30, 2011, the allowance for loan losses allocation on these loans amounted to $900 thousand.

During the six months endedJune 30, 2011, properties acquired through foreclosures or repossession with a fair value of $801 thousand were transferred from loans.  Prior to the transfer, the assets whose fair value less costs to sell was less than the carrying value were written down to fair value through a charge to the allowance for loan losses. For the three and six months endedJune 30, 2011, such valuation adjustments charged to the allowance for loan losses amounted to $124 thousand.  Subsequent to foreclosures, valuations are updated periodically and assets may be marked down further, reflecting a new cost basis. Subsequent valuation adjustments charged to earnings totaled $238 thousand for the three and six months endedJune 30, 2011.

The following table presents additional quantitative information about assets measured at fair value on a nonrecurring basis for which the Corporation has utilized Level 3 inputs to determine fair value.

(Dollars in thousands)	June 30, 2012
	Fair Value		Valuation Technique	Unobservable Input	Range of Inputs Utilized (Weighted Average)
Collateral dependent impaired loans		$2,792	Appraisals of collateral	Discount for costs to sell	0% - 50% (18%)
				Appraisal adjustments (1)	10% - 15% (15%)
Property acquired through foreclosure or repossession		$1,070	Appraisals of collateral	Discount for costs to sell	0% - 15% (8%)

(1) Management may adjust appraisal values to reflect market value declines or other discounts resulting from its knowledge of the property.

Carrying Amounts and Estimated Fair Values of Financial Instruments
