The Federal Home Loan Bank system earned $484 million in the third quarter of 2015 and attributes the 23 percent year-over-year decrease to net losses on derivatives and hedging activities. But total net income for the first nine months of the year saw a 29 percent jump, to $2.18 billion, according to figures compiled by the system’s Office of Finance. This was driven by higher litigation settlements and net gains on derivatives and hedging activities. After falling flat last quarter, total FHLB assets from the end of June were up at the end of the third quarter by less than 1 percent to $919.6 billion.
