Primary net income per share is computed by dividing net income by the weighted
average number of shares of common stock and common stock equivalents
outstanding during the period. Common stock equivalents include the Company's
stock options. Fully diluted net income per share is computed based on the
weighted average number of shares of common stock and common stock equivalents
outstanding during the period and as if the Company's convertible subordinated
debentures were converted into common stock at the beginning of the period after
giving retroactive effect to the elimination of interest expense, net of income
tax effect, applicable to the convertible subordinated debentures.
