Common Stock Repurchase Program [Abstract] |
Common Stock Repurchase Program | 11. Common Stock Repurchase Program In November 2009, we announced a stock repurchase program, whereby we may repurchase up to $250.0 million of our Class A common stock. Our Board of Directors approved an additional $300.0 million for our stock repurchase program in July 2010, and an additional $250.0 million in July 2011, for a total authorization of up to $800.0 million in stock repurchases. Stock repurchases under this program may be made through open market transactions, negotiated purchases, or otherwise, at times and in amounts that we consider appropriate. The timing of repurchases and the number of shares repurchased depend upon a variety of factors, including price, regulatory requirements, the rate of dilution from our equity compensation programs, and other market conditions. We may limit, suspend, or terminate the stock repurchase program at any time without prior notice. This program does not have a specified expiration date. Shares repurchased under the program will be returned to the status of authorized but unissued shares of Class A common stock. Stock repurchase activity under the stock repurchase program during fiscal 2011 is summarized as follows:
|  | Shares Repurchased |  |  | Cost (in thousands) (1) |  |  | Average Price Paid per Share (2) |
Repurchase activity for the fiscal quarter ended December 31, 2010 |  |  | 732,665 |  |  | $ | 45,966 |  |  | $ | 62.72 |
Repurchase activity for the fiscal quarter ended April 1, 2011 |  |  | 546,940 |  |  |  | 29,158 |  |  |  | 53.30 |

- Definition Tabular disclosure of accelerated share repurchase (ASR) programs. An ASR is a combination of transactions that permits an entity to purchase a targeted number of shares immediately with the final purchase price of those shares determined by an average market price over a fixed period of time. An accelerated share repurchase program is intended to combine the immediate share retirement benefits of a tender offer with the market impact and pricing benefits of a disciplined daily open market stock repurchase program. ASRs can be disclosed as part of stockholders' equity. + References Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Emerging Issues Task Force (EITF) -Number 99-7 -Paragraph 1 -LegacyDoc This reference is SUPERSEDED by the Accounting Standards Codification effective for interim and annual periods ending after September 15, 2009.
