The repurchase authorization does not require the repurchase of a specific number of shares, has an indefinite term, and is subject to termination at any time by our board of directors. During the nine months ended September 30, 2014, we repurchased 1.3 million shares of our common stock in the open market for $43.1 million using cash on hand.On February 14, 2014, our board of directors declared a cash dividend of $0.18 per common share that was paid on April 15, 2014 to stockholders of record on April 1, 2014. On May 1, 2014, our board of directors declared a cash dividend of $0.18 per common share that was paid on July 15, 2014 to stockholders of record on July 1, 2014. On July 17, 2014, our board of directors approved an increase in our quarterly dividend and declared a cash dividend of $0.21 per common share paid on October 15, 2014 to stockholders of record on October 1, 2014. On October 21, 2014, our board of directors declared a cash dividend of $0.21 per share, payable on January 15, 2015 to stockholders of record on January 2, 2015. As of September 30, 2014 and December 31, 2013, accrued common stock dividends of $18.7 million and $15.8 million were included in Accrued expenses and other current liabilities in our condensed consolidated balance sheet. Future dividend payments are subject to declaration by our board of directors.As discussed more fully in Note 10, Convertible Perpetual Preferred Stock, to the consolidated financial statements accompanying the 2013 Form 10-K, the agreement underlying our preferred stock includes antidilutive protection that requires adjustments to the number of shares of common stock issuable upon conversion and the exercise price for common stock upon the occurrence of certain events, including payment of cash dividends on our common stock after a de minimis threshold. At issuance, the preferred stock had a conversion price of $30.50 per share, which was equal to an initial conversion rate of 32.7869 shares of common stock per share of preferred stock. Additionally, our convertible notes (see Note 8, Long-term Debt, to the consolidated financial statements accompanying the 2013 Form 10‑K) also include similar antidilutive protection that requires adjustments to the number of shares of common stock issuable upon conversion and the exercise price for common stock upon the occurrence of certain events, including payment of cash dividends on our common stock after a de minimis threshold. At issuance, the convertible notes had a conversion price of $39.65 per share, which was equal to an initial conversion rate of 25.2194 shares per $1,000 principal amount of the convertible notes. The payment of dividends beginning in October 2013 has triggered, from time to time, the antidilutive adjustment provisions of the preferred stock and convertible notes. As of October 2, 2014, the resulting exercise prices of the preferred stock and convertible notes were $29.70 and $38.82 per share, respectively, and the resulting conversion rates were 33.6700 and 25.7582 for each preferred share and for each $1,000 principal amount of the convertible notes, respectively.In January 2004, we repaid our then-outstanding 3.25% Convertible Debentures using the net proceeds of a loan arranged by Credit Suisse First Boston. In connection with this transaction, we issued ten million warrants with an expiration date of January 16, 2014 to the lender to purchase shares of our common stock. The following table summarizes information relating to these warrants and their activity from December 31, 2013 through their expiration date (number of warrants in millions): Number of Warrants Weighted Average Exercise PriceCommon stock warrants outstanding as of December 31, 20132.9 $32.50Cashless exercise(1.8) 32.16Cash exercise(1.0) 32.16Expired(0.1) 32.16Common stock warrants outstanding as of January 16, 2014—  The above exercises resulted in the issuance of 0.2 million shares of common stock during the nine months ended September 30, 2014. Cash exercises resulted in gross proceeds of $6.3 million during the nine months ended September 30, 2014.See Note 10, Convertible Perpetual Preferred Stock, and Note 17, Earnings per Common Share, to the consolidated financial statements accompanying the 2013 Form 10-K for additional information related to common stock, common stock warrants, and convertible perpetual preferred stock. |
