For the three months and nine months ended September 30, 2011 and 2010, the Company allocated dividends to the unvested restricted stock awards (participating securities).
Additionally, 37 million common shares for the three months and nine months ended September 30, 2011 and 2010 related to stock options were excluded from the computation of diluted earnings per common share due to their antidilutive effect.
    In the first nine months of 2011, the Company granted 2 million shares of long-term stock awards; to offset the dilutive impact of these awards, the Company also repurchased and retired approximately 2 million shares of Company common stock, for cash aggregating $30 million. At September 30, 2011, the Company had 25 million shares of its common stock remaining under the July 2007 Board of Directors repurchase authorization.
    On the basis of amounts paid (declared), cash dividends per common share were $.075 ($.075) and $.225 ($.225), respectively, for the three months and nine months ended September 30, 2011 and the three months and nine months ended September 30, 2010.
