The forecasted adjusted diluted earnings per share are based on management’s estimates for fiscal year 2010 and the first quarter of fiscal 2010.  The company expects to incur charges for severance and merger costs during those periods, and the amounts are dependent upon future events.  The company will use adjusted diluted earnings per share to evaluate its performance and believes this information is helpful to shareholders.
