"After our thorough evaluation of the CMO portfolio, including the substantial level of prepayments received in recent months as well as those expected to continue for the foreseeable future, we recorded an adjustment of $16 million to accelerate the premium amortization," said Mr. Norwood.  "With this adjustment, the remaining premium has been reduced to $74 million, or 1.6% of par at December 31, 2012, significantly reducing potential future volatility in our CMO yields."
