The Federal Home Loan Bank Office of Finance announced that preliminary combined net income for the FHLBanks rose 86.9 percent to $469 million for the three-month period that ended Sept. 30, 2011. That was down from $732 million at the end of the third quarter 2010.For the first nine months of the year, the FHLBanks earned $1.08 billion, $305 million less than the Banks earned during the same time last year. The Office of Finance attributed the changes to lower net interest income, partially offset by other non-interest losses and lower assessments.
