Diluted earnings per share includes only the dilutive effects of common stock equivalents such as stock options. Anti-dilutive stock options, restricted stock and restricted stock units totaling 1,254 for the three months ended September 30, 2010 were excluded from our earnings per share calculations. There were no anti-dilutive stock options or restricted shares for the three months ended September 30, 2011.
