The table below presents the average recorded investment of individually impaired loans and related interest income recognized. The Bank included the individually impaired loans as of the date on which they became a TDR. However, prior to third quarter 2011 conventional MPF loans were not accounted for as TDRs because they were deemed to be immaterial. Deferred BOB loans were deemed to be TDRs effective July 1, 2011.
