For the nine months ending September 30, 2006, net income was $4,528,000 as compared to $5,256,000 for the first nine months of 2005. Earnings per share amounted to $1.04 for the nine months ending September 30, 2006, a decrease of 13.3% from the $1.20 reported in the first nine months of 2005. Cash dividends per share amounted to $.66 for the nine months ending September 30, 2006, an increase of 10.0% from the $.60 paid in the first nine months of 2005. Annualized return on assets and return on equity were 1.16% and 11.54%, respectively, for the first nine months ending September 30, 2006. The reduction in earnings was a result of lower net interest income due to a flatten yield curve and compression in the net interest margin. The reduced net interest income was partially offset by tighter expense control, a lower loan loss provision, and higher non interest revenue. The Board of Directors of First Keystone Corporation approved a 5% stock dividend payable on December 5, 2006 to shareholders of record on November 14, 2006. The First National Bank of Berwick, an independently owned community bank since 1864, presently operates 10 full service offices in Columbia (5), Luzerne (4), and Montour (1) Counties providing banking and trust services.
