[1] Relates to certain impaired collateral dependent loans. The impairment was measured based on the fair value of collateral, in accordance with U.S. GAAP. The unobservable inputs for Level 3 impaired loans did not change between December 31, 2013 and June 30, 2013. The gain related to loans measured for impairment noted above result primarily from principal pay downs on impaired loans during the period.

[2] Relates to certain impaired other real estate owned. This impairment arose from an adjustment to the Company’s estimate of the fair market value of these properties based on changes in estimated costs to complete the projects and changes in market conditions. The Company took a weighted average discount of 13% on impaired other real estate owned classified as Level 3 assets.
