Stock Repurchase Program

In August 2011, the Board of Directors approved an increase in the aggregate amount under its previously announced share repurchase program from $350.0 million to $500.0 million after expanding the authorization in May 2011 by $100.0 million from the $250.0 million originally approved by the Board in February 2010. Since announcing the share repurchase program in February 2010, CCA completed the purchase of 17.7 million shares at a cost of $383.2 million through December 31, 2011, or an average price of $21.63 per share. CCA utilized cash on hand, net cash provided by operations, and borrowings available under the Revolving Credit Facility to fund the repurchases. In February 2012, the share repurchase program was terminated in conjunction with the announcement to commence a quarterly cash dividend beginning in the second quarter of 2012. There were no share repurchases in 2012.

Restricted Stock

During the first quarter of 2012, CCA issued 346,000 shares of restricted common stock and common stock units to certain of its employees and non-employee directors, with an aggregate fair value of $9.1 million, including 287,000 restricted shares or units to employees and non-employee directors whose compensation is charged to general and administrative expense and 59,000 restricted shares to employees whose compensation is charged to operating expense. During 2011, CCA issued 265,000 shares of restricted common stock and common stock units to certain of its employees and non-employee directors, with an aggregate fair value of $6.5 million, including 227,000 restricted shares or units to employees and non-employee directors whose compensation is charged to general and administrative expense and 38,000 restricted shares to employees whose compensation is charged to operating expense.

CCA established performance-based vesting conditions on the shares of restricted common stock and common stock units awarded to its officers and executive officers. Unless earlier vested under the terms of the agreements, shares or units issued to officers and executive officers are subject to vesting over a three-year period based upon the satisfaction of certain performance criteria. No more than one-third of such shares or units may vest in the first performance period; however, the performance criteria are cumulative for the three-year period. Unless earlier vested under the terms of the agreements, the shares of restricted stock issued to the other employees vest after three years of continuous service. Shares of restricted stock units issued to non-employee directors vest on April 30, 2013.

During the three months ended March 31, 2012, CCA expensed $1.6 million, net of forfeitures, relating to restricted common stock and common stock units ($0.2 million of which was recorded in operating expenses and $1.4 million of which was recorded in general and administrative expenses). During the three months ended March 31, 2011, CCA expensed $1.5 million, net of forfeitures, relating to restricted common stock and common stock units ($0.3 million of which was recorded in operating expenses and $1.2 million of which was recorded in general and administrative expenses). As of March 31, 2012, approximately 810,000 shares of restricted common stock and common stock units remained outstanding and subject to vesting.

Stock Options

During the three months ended March 31, 2012, CCA issued to its non-employee directors, officers, and executive officers options to purchase 706,000 shares of common stock with an aggregate fair value of $5.3 million, with a weighted average exercise price of $26.26 per share. During 2011, CCA issued to its officers, executive officers, and non-employee directors options to purchase 575,000 shares of common stock with an aggregate fair value of $5.6 million, with a weighted average exercise price of $24.45 per share. CCA estimates the fair value of stock options using the Black-Scholes option pricing model. Unless earlier vested under their terms, one third of the stock options issued to CCA's executive officers vest on the anniversary of the grant date over a three-year period while one fourth of the stock options issued to CCA's other officers vest on the anniversary of the grant date over a four-year period. Options granted to non-employee directors vest on April 30, 2013.

During the three months ended March 31, 2012 and 2011, CCA expensed $1.1 million and $1.2 million, respectively, net of forfeitures, relating to its outstanding stock options. As of March 31, 2012, options to purchase 4.2 million shares of common stock were outstanding with a weighted average exercise price of $20.36.
