[1] Covered OREO results from the WFIB and UCB FDIC-assisted acquisitions for which the Company entered into shared-loss agreements with the FDIC whereby the FDIC will reimburse the Company for 80% of eligible losses. As such, the Company's liability for losses is 20% of the $126 thousand in losses, or $25 thousand, and 20% of the $6.4 million in losses, or $1.3 million, for the three months ended March 31, 2013 and 2012, respectively.
