Capital Stock | 12. Capital Stock Incentive Plans Under the Company's 2004 Incentive Plan, incentive and non-statutory stock options, stock appreciation rights (SARs), stock awards, cash awards and performance awards may be granted to key employees, consultants and officers of the Company. Non-employee directors of the Company may be granted discretionary awards under the 2004 Incentive Plan consisting of stock options or stock awards. A total of 20.4 million shares of common stock may be issued under the 2004 Incentive Plan. Under the 2004 Incentive Plan, no more than 7.2 million shares may be used for stock awards that are not subject to the achievement of performance based goals, and no more than 12.0 million shares may be issued pursuant to incentive stock options. The 2004 Incentive Plan expires on April 29, 2014. At December 31, 2013, 1.7 million shares are available for issuance under the plan. Common Stock In May 2012, the stockholders of the Company approved an increase in the authorized number of shares of common stock from 240 million to 480 million shares. On July 23, 2013, the Board of Directors declared a 2-for-1 split of the Company's common stock in the form of a stock dividend. The stock dividend was distributed on August 14, 2013 to shareholders of record as of August 6, 2013. All common stock accounts and per share data were retroactively adjusted to give effect to the 2-for-1 split of the Company's common stock. Treasury Stock The Board of Directors has authorized a share repurchase program under which the Company may purchase shares of common stock in the open market or in negotiated transactions. The timing and amount of these stock purchases are determined at the discretion of management. The Company may use the repurchased shares to fund stock compensation programs presently in existence, or for other corporate purposes. All purchases executed to date have been through open market transactions. There is no expiration date associated with the authorization to repurchase securities of the Company. During the year ended December 31, 2013, the Company repurchased 4.8 million shares for a total cost of $164.6 million. In 2012 and 2011, the Company did not repurchase any shares of common stock. Since the authorization date, the Company has repurchased 25.6 million shares of the 40.0 million total shares authorized for a total cost of approximately $249.7 million, of which 20.0 million shares have been retired. No treasury shares have been delivered or sold by the Company subsequent to the repurchase. As of December 31, 2013, 5.6 million shares were held as treasury stock. Dividend Restrictions The Board of Directors of the Company determines the amount of future cash dividends, if any, to be declared and paid on the common stock depending on, among other things, the Company's financial condition, funds from operations, the level of its capital and exploration expenditures, and its future business prospects. None of the note or credit agreements in place have restricted payment provisions or other provisions limiting dividends.
