Earnings Per Share [Abstract]

EARNINGS PER SHARE

NOTE K – EARNINGS PER SHARE

     The following table sets forth the numerators and denominators used in the computation of basic and diluted earnings per share for the three and nine months ended June 30, 2011 and 2010. Due to their antidilutive effect, the computation of diluted earnings per share excluded options to purchase 9.6 million and 9.5 million shares of common stock for the three and nine months ended June 30, 2011, respectively, and options to purchase 9.5 million and 9.7 million shares of common stock for the same periods of 2010. Additionally, for all periods except the nine-month period ended June 30, 2010, the convertible senior notes were excluded from the computation because their effect would have been antidilutive.
