Earnings Per Share [Abstract]

EARNINGS PER SHARE

EARNINGS PER SHARE

The following table sets forth the numerators and denominators used in the computation of basic and diluted earnings per share. Options to purchase 6.7 million and 4.0 million shares of common stock were excluded from the computation of diluted earnings per share for the three months ended December 31, 2013 and 2012, respectively, because the exercise price of the options was greater than the average market price of the common shares and, therefore, their effect would have been antidilutive.
