Fair Value Inputs, Assets, Quantitative Information

The range and weighted-average of the significant unobservable inputs used to fair value our Level 3 nonrecurring assets, along with the valuation techniques used, are shown in the following table:

	Fair value  at June 30, 2012		Valuation Technique	Unobservable Input	Range (Weighted Average) (1)
	(dollars in thousands)
Impaired loans - real estate collateral	$	11,896	Market	Adjustment to Appraisal Value	N/A (2)
Impaired loans - other collateral (3)	2,243		Market	Adjustment to stated value	0% - 70% (27%)

(1) Discount applied to appraisal value, letter of intent to purchase, or stated value (in the case of accounts receivable and inventory).
(2) Quantitative disclosures are not provided for impaired loans collateralized by real estate, noncovered OREO, covered OREO and noncovered OPPO because there were no adjustments made to the appraisal value during the current period.
(3) Other collateral consists of accounts receivable and inventory.
