For fiscal 1996 and 1995 common stock equivalents related to shares issuable
under options outstanding did affect the per share amount and, accordingly were
included in the computation. Common stock equivalents related to shares
issuable under options outstanding did not significantly affect the per share
amount and, accordingly, were not included in the computation for fiscal 1994.
