     of 1934, Release No. 9083, although in certain instances, it is contrary to
     paragraph 40 of APB Opinion No. 15 because it produces an anti-dilutive
     result.

(3)  APB 15 paragraph 30 indicates computation of primary earnings per share
     should not give effect to common stock equivalents if their inclusion has
     the effect of decreasing the loss per share amount otherwise computed or is
