Earnings Per Share and Common Stock [Abstract] |
Earnings Per Share and Common Stock [Text Block] | EARNINGS PER SHARE AND COMMON STOCK The difference between basic and diluted earnings per share, if any, arises from outstanding stock options, non-vested restricted stock units, and performance share awards granted under our Executive Long-Term Incentive Compensation Plan. For the quarters and six months ended June 30, 2013 and 2012, zero and 0.3 million options to purchase shares of common stock, respectively, were excluded from the computation of diluted earnings per share because the option exercise prices were greater than the average market prices; therefore, their effect would have been anti-dilutive.
