Such comments are based upon the information currently available to management of the Company and management’s perception thereof as of the date of this release.  Actual results of the Company’s operations could materially differ from those forward-looking comments.  The differences could be caused by a number of factors or combination of factors including, but not limited to: changes in demand for banking services; changes in portfolio composition; changes in management strategy; increased competition from both bank and non-bank companies; changes in the general level of interest rates; the effect of regulatory or government legislative changes; technology changes; and fluctuation in inflation.
