Fair Value Inputs, Fair Value Measured On a Recurring Basis, Quantitative Information [Table Text Block]

A summary of quantitative information about assets measured at fair value on a recurring basis using significant unobservable inputs (Level 3) as of June 30, 2013 follows (in thousands):

Quantitative Information about Level 3 Recurring Fair Value Measurements
	Par Value		Amortized Cost6		Fair Value		Valuation Technique(s)		Unobservable Input	Range (Weighted Average)
Available for sale securities
Municipal and other tax-exempt securities
Investment grade	$	28,470	$	28,375	$	27,116	Discounted cash flows	1	Interest rate spread	4.99%-5.49% (5.24%)	2
										95.01%-95.6% (95.25%)	3
Below investment grade	17,000		12,384		11,731		Discounted cash flows	1	Interest rate spread	9.15%-11.19% (9.87%)	4
										68.91%-69.09% (69.01%)	3
Total municipal and other tax-exempt securities	45,470		40,759		38,847
Other debt securities	5,400		5,400		5,193		Discounted cash flows	1	Interest rate spread	4.41%-5.69% (5.48%)	5
										96.13%-96.16% (96.16%)	3
Equity securities and mutual funds	N/A		2,420		2,247		Tangible book value per share of publicly traded financial institutions of similar size, less liquidity discount.		Peer group tangible book per share and liquidity discount.	N/A	7
Other assets - private equity funds	N/A		N/A		28,379		Net asset value reported by underlying fund		Net asset value reported by underlying fund	N/A

¹  Discounted cash flows developed using discount rates primarily based on reference to interest rate spreads for comparable securities of similar duration and credit rating as determined by the nationally-recognized rating agencies, adjusted for lack of trading volume

²  Interest rate yields used to value investment grade tax-exempt securities represent a spread of 457 to 520 basis points over average yields for comparable tax-exempt securities.

³  Represents fair value as a percentage of par value

⁴  Interest rate yields determined using a spread of 700 basis points over comparable municipal securities of varying durations.

⁵  Interest rate yields used to value investment grade taxable securities based on comparable short-term taxable securities which are generally yielding less than 1%.

⁶  Amortized cost reduced by other-than-temporary impairments recorded in earnings. See Note 2 for additional discussion.

⁷  Fair value of shares of a smaller privately-held financial institution were valued using the tangible book value per share of similarly sized financial institutions within the immediate geographical market with a discount of 20% due to the liquidity of the shares.

The fair value of these securities measured at fair value using significant unobservable inputs are sensitive primarily to changes in interest rate spreads. At June 30, 2013, for tax-exempt securities rated investment grade by all nationally-recognized rating agencies, a 100 basis point increase in the spreads over average yields for comparable securities would result in an additional decrease in the fair value of $262 thousand. For taxable securities rated investment grade by all nationally-recognized rating agencies, a 100 basis point increase in the spreads over average yield for comparable securities would result in an additional decrease in the fair value of $50 thousand. For municipal and other tax-exempt securities rated below investment grade by at least one of the nationally-recognized rating agencies, a 100 basis point increase in the spread over average yields for comparable securities would result in an additional decrease in the fair value of these securities of $330 thousand.
