The dilutive effect of stock options, stock purchase warrants, and stock 
purchase plan rights are calculated using the treasury stock method. Under 
this method, these common stock equivalents are assumed to be exercised and 
proceeds from the exercise are assumed to be used to repurchase common stock 
at the average market price for primary income (loss) per share and the 
higher of the end of the period or average market price for fully diluted 
income (loss) per share. The dilutive effect of Convertible Preferred Stock 
is calculated using the if-converted method.
