Net interest margin increased 36 basis points to 4.09% for the quarter ended March 31, 2010 as compared to 3.73% for the quarter ended March 31, 2009. The increases in net interest spread and net interest margin were primarily due to the continued decline in the rates paid on deposits, partially offset by purchases of securities at lower yields. The increase in average balances, along with the widening of the net interest spread and net interest margin led to an increase in net interest income when comparing the nine months and quarters ended March 31, 2010 and 2009.
