Note J — Earnings Per Share

Basic earnings per share is based on the weighted average number of shares outstanding during each period. Diluted earnings per share further assumes that the zero coupon, convertible subordinated notes, if dilutive, are converted as of the beginning of the period and that, under the treasury stock method, dilutive stock options are exercised. Net earnings under this assumption have been adjusted for interest on the zero coupon, convertible subordinated notes, net of the related income tax effect.

The information required to compute basic and diluted net earnings per share is as follows:

For 2000, the zero coupon convertible subordinated notes would have been anti-dilutive, and therefore the shares (23.0 million) and related interest expense ($12.1 million) were excluded from our calculation of diluted earnings per share. Options to purchase 12.7 million shares of common stock were not included in our computation of diluted earnings per share for 2001 because their effect would also have been anti-dilutive.
