Earnings per Common Share [Abstract]

Earnings per Common Share

9. Earnings per Common Share

The calculation of earnings per common share is based on the weighted-average number of our common shares outstanding during the applicable period. The calculation for diluted earnings per common share recognizes the effect of all dilutive potential common shares that were outstanding during the respective periods, unless their impact would be antidilutive. The following table sets forth the computation of basic and diluted earnings per common share (in millions, except per share amounts):

Diluted earnings per share report the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock. These potential shares include dilutive stock options, restricted stock awards, restricted stock units, and convertible perpetual preferred stock. For the three and nine months ended September 30, 2011, the number of potential shares approximated 15.9 million. For the three and nine months ended September 30, 2010, the number of potential shares approximated 15.5 million and 15.6 million, respectively. For the three and nine months ended September 30, 2011 and 2010, approximately 13.1 million of the potential shares related to our Convertible perpetual preferred stock. For the three and nine months ended September 30, 2011 and 2010, adding back the dividends for the Convertible perpetual preferred stock to our Income from continuing operations attributable to HealthSouth common shareholders causes a per share increase when calculating diluted earnings per common share resulting in an antidilutive per share amount. Therefore, basic and diluted earnings per common share are the same for all periods presented.

Options to purchase approximately 1.1 million and 2.0 million shares of common stock were outstanding as of September 30, 2011 and 2010, respectively, but were not included in the computation of diluted weighted-average shares because to do so would have been antidilutive.

In October 2011, our board of directors authorized the repurchase of up to $125 million of our common stock. The repurchase authorization does not require the repurchase of a specific number of shares, has an indefinite term, and is subject to termination by our board of directors. Subject to certain terms and conditions, including compliance with federal and state securities and other laws, the repurchases may be made from time to time in open market transactions, privately negotiated transactions, or other transactions, including trades under a plan established in accordance with Rule 10b5-1 under the Securities Exchange Act of 1934, as amended. Repurchases under this authorization, if any, are expected to be funded using cash on hand and availability under our revolving credit facility.

Our board of directors also granted discretion to management to opportunistically repurchase from time to time, subject to similar conditions, warrants issued pursuant to the warrant agreement, dated as of January 16, 2004, with Wells Fargo Bank Northwester, N.A., as warrant agent. Likewise, this authority does not require the purchase of a specific number of warrants, has an indefinite term, and is subject to termination by our board of directors.
