Description Of Sale Of Other Real Estate Owned Properties			We incurred higher than usual commission and closing costs due to the size of the transaction. If sold on an individual basis, it is unlikely that we would have taken this type of charge against these properties. However, if this transaction goes through under these terms, it would represent a 56% decrease to our other real estate owned properties balance of $36.5 million as of June 30, 2012.
