STOCKHOLDERS' EQUITY

Issuance of Common Stock. On June 22, 2011, we completed an equity public offering of 5,520,000 shares of Common Stock and received proceeds of approximately $87.7 million, which is net of approximately $4.6 million in underwriting discounts and commissions and approximately $127,000 in other direct costs incurred and paid by us in connection with this equity offering.

Stock Split. On April 21, 2011, our Board of Directors authorized a 5-for-4 forward stock split of our Common Stock, which was effected in the form of a stock dividend of one share of Common Stock for every four shares of Common Stock outstanding on the record date. On May 5, 2011, we completed the forward stock split through a stock dividend to shareholders of record as of May 2, 2011. Our Board of Directors also made corresponding adjustments to the number of shares subject to, and the exercise price of, outstanding options and other rights to acquire shares of our Common Stock. All earnings per common share and common share data set forth in the foregoing consolidated financial statements (and notes thereto) have been adjusted to reflect the split.

Repurchase of Our Common Stock. On April 30, 2007, our Board of Directors approved the repurchase of up to 1.4 million shares of Common Stock. During the first quarter of 2009, we repurchased a total of 250,158 shares of Common Stock for approximately $2.5 million. We did not repurchase any shares of Common Stock during 2011 and 2010.
