The Federal Home Loan Bank of Des Moines on Tuesday released preliminary unaudited financial results for the quarter that ended March 31. The bank recorded net income of $37 million for the quarter, compared with $27.3 million for the same period in 2013, driven primarily by net interest income and other income. Net interest income totaled $52.4 million for the most recent quarter, a slight decrease from $53.3 million for the year-ago quarter due to lower advance prepayment fee income. Other income for the quarter totaled $3.4 million, compared with a loss of $7.7 million a year ago. The bank's total assets decreased slightly to $72.9 billion at March 31, 2014, from $73 billion at Dec. 31, 2013, due primarily to a decline in advances and mortgage loans, partially offset by an increase in investments.
