The most significant factor contributing to the higher earnings was higher net interest income, which increased to $17.7 million for the year ended June 30, 2010 as compared to $15.7 million for the year ended June 30, 2009, an increase of $2.0 million or 12.7%.

Net interest rate spread increased 18 basis points to 3.72% for the year ended June 30, 2010 as compared to 3.54% for the year ended June 30, 2009. Net interest rate spread increased 23 basis points to 3.71% for the quarter ended June 30, 2010 as compared to 3.48% for the quarter ended June 30, 2009. Net interest margin increased 11 basis points to 3.91% for the year ended June 30, 2010 as compared to 3.80% for the year ended June 30, 2009. Net interest margin increased 20 basis points to 3.90% for the quarter ended June 30, 2010 as compared to 3.70% for the quarter ended June 30, 2009. The increases in net interest spread and net interest margin were primarily due to the continued decline in the rates paid on deposits and borrowings, 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 years and quarters ended June 30, 2010 and 2009.
