For the nine months ending September 30, 2004, net income was $5,434,000 as compared to $5,469,000 for the first nine months of 2003.

Annualized return on assets and return on equity were 1.47% and 13.80%, respectively, for the first nine months ending September 30, 2004. President J.

The increase in the provision for loan losses was to maintain an allowance for loan losses at a level which management considers its best estimate of known and probable inherent losses since a large commercial credit was recently put on non-accrual status." Total assets increased to $497,599,000 as of September 30, 2004, an increase of 4.0% over 2003. In addition, total deposits increased $10,805,000 to $363,276,000 as of September 30, 2004. Cash dividends paid for the first three quarters of 2004 were $.53 as compared to $.48 for the first three quarters of 2003, an increase of 10.4%.
