Intangible Assets [Abstract]

Summary of amortizable intangible assets

(in thousands)		March 31, 2013												December 31, 2012
		Gross Carrying Amount				Accumulated Amortization				Net Amount				Gross Carrying Amount				Accumulated Amortization				Net Amount
Core deposit intangible		$	4,795			$	(4,761	)		$	34			$	4,795			$	(4,660	)		$	135

Changes in the net carrying amount of core deposit intangible assets

		Three Months Ended March 31,
(in thousands)		2013				2012
Balance at beginning of year		$	135			$	543
Additions			0				0
Amortization			(101	)			(104	)
Balance at end of year		$	34			$	439

Changes in mortgage servicing rights

		Three Months Ended March 31,
(in thousands)		2013				2012
Balance at beginning of period		$	2,549			$	2,308
Re-measurement to fair value upon election to measure servicing rights at fair value			0				742
Originated mortgage servicing rights			197				182
Changes in fair value:
Due to change in model inputs and assumptions(1)			194				170
Other changes in fair value(2)			(251	)			(655	)
Balance at end of period		$	2,689			$	2,747

(1) The change in fair value resulting from changes in valuation inputs or assumptions used in the valuation model reflects the change in discount rates and prepayment speed assumptions primarily due to changes in interest rates.

(2) Other changes in fair value reflect changes due to customer payments and passage of time. This also includes a one time adjustment of a $538,000 correction of an immaterial prior period error in 2012 due to changing from the straight-line amortization method to an accelerated amortization method of accounting for amortizing MSRs in prior years. If the aforementioned was corrected as of December 31, 2011, the balance at the beginning of the three month period ending March 31, 2012 would have been $1,770,000.

Assumptions used in estimating the fair value of mortgage service rights

		Three Months Ended March 31,

Weighted-Average Note Rate			4.12	%			4.55	%

- Definition

Tabular disclosure of the characteristics, including initial carrying value, residual amount, weighted average useful life, of finite-lived intangible assets acquired during the period by major class. A major class is composed of intangible assets that can be grouped together because they are similar, either by nature or by their use in the operations of the company.

- Definition

Tabular disclosure of all information related to the key inputs and assumptions used in measuring the fair value of assets obtained or liabilities incurred, as the result of a sale of financial assets, relating to the transferor's continuing involvement, if any, at the time of securitization, asset-backed financing arrangement, or similar transfer (including at a minimum, but not limited to, and if applicable, quantitative information about discount rates, expected prepayments including the expected weighted-average life of prepayable financial assets, and anticipated credit losses, including expected static pool losses).
