The calculation of diluted earnings per share for the three and nine months ended June 30, 2012 and 2011 excludes shares of common stock related to approximately 672,000 and 684,000 outstanding stock options, respectively, because such options were anti-dilutive. These options could potentially dilute basic earnings per share in the future.
