In October 2016, February 2017, and May 2017, our board of directors declared cash dividends of $0.24 per share that were paid in January 2017, April 2017, and July 2017, respectively. On July 20, 2017, our board of directors approved an increase in our quarterly dividend and declared a cash dividend of $0.25 per share that was paid on October 16, 2017 to stockholders of record on October 2, 2017. On October 20, 2017, our board of directors declared a cash dividend of $0.25 per share, payable on January 16, 2018 to stockholders of record on January 2, 2018. As of September 30, 2017 and December 31, 2016, accrued common stock dividends of $25.3 million and $22.2 million, respectively, were included in Accrued expenses and other current liabilities in our condensed consolidated balance sheets. Future dividend payments are subject to declaration by our board of directors.

On September 30, 2009, we issued 5.0 million shares of common stock and 8.2 million common stock warrants in full satisfaction of our obligation to do so under the January 2007 comprehensive settlement of the consolidated securities action brought against us by our stockholders and bondholders. Under the terms of the related warrant agreement, the warrants were exercisable at a price of $41.40 per share by means of a cash or a cashless exercise at the option of the holder. The warrants were not assumed exercised for dilutive shares outstanding because they were antidilutive in the periods presented. The warrants expired on January 17, 2017.

The following table summarizes information relating to these warrants and their activity through their expiration date (number of warrants in millions):



	Number of Warrants		Weighted-Average Exercise Price
Common stock warrants outstanding as of December 31, 2016	8.2		$	41.40
Cashless exercise	(6.5	)	41.40
Cash exercise	(0.6	)	41.40
Expired	(1.1	)	41.40
Common stock warrants outstanding as of January 17, 2017	—

The above exercises resulted in the issuance of 0.7 million shares of common stock. Cash exercises resulted in gross proceeds of approximately $27 million.
