President's Statement

Within this press release you will find details of our 2012 fourth quarter and for the entire 2012 year.  For the fourth quarter, earnings exceeded $1,000,000, now the 6^th straight quarter we have reached that mark. For the 2012 year, earnings were up over 10% compared with 2011 results. We would classify 2012 as a good year, but recognize we are capable of even better performance going forward.

We continue to have a positive outlook for the Bank's future based on our most recent past.  We consider the fourth quarter of 2012 to be yet another step in a positive direction and one that places us in a position for strong performance in 2013.
