STOCKHOLDERS' EQUITY |
STOCKHOLDERS' EQUITY | (10) STOCKHOLDERS' EQUITY Common Stock In April 2010, the Company filed a shelf registration statement with the Securities and Exchange Commission to register for sale any combination of the types of securities described in the shelf registration statement up to a dollar amount of $150 million. The shelf registration went effective on April 22, 2010. In December 2012, the Company filed a new shelf registration statement with the Securities and Exchange Commission to register for sale any combination of the types of securities described in the new shelf registration statement up to a dollar amount of $200 million. The new shelf registration went effective on January 16, 2013. In January 2011, the Company entered into a controlled equity offering sales agreement (the "Cantor Agreement") with Cantor Fitzgerald & Co. ("Cantor") pursuant to which the Company could issue and sell up to 5,000,000 shares of its common stock from time to time through Cantor, acting as agent. During the years ended December 31, 2012 and 2011, the Company issued 4,425,000 and 575,000 shares of common stock under the Cantor Agreement and raised $19.0 million and $2.2 million in net proceeds, after deducting commission and offering expenses, respectively. In September 2012, the Company and Cantor amended the Cantor Agreement (the "Cantor Amendment") to allow the Company to issue and sell additional shares of its common stock having an aggregate offering price of up to $44.0 million. Under the Cantor Amendment, the Company will pay Cantor a fixed commission rate of 3.0% of the gross sales price per share of any common stock sold through Cantor. The Cantor Amendment terminates upon ten day notice by either Cantor or the Company. During the year ended December 31, 2012, the Company issued 3,578,290 shares under the Cantor Amendment and raised $21.1 million in net proceeds. During January 2013, the Company issued 2,433,608 shares under the Cantor Amendment and raised $17.1 million in net proceeds. At February 28, 2013, the Company had $4.4 million remaining in aggregate offering price available under the Cantor Amendment which may be sold upon the expiration of the 90-day lock-up with the underwriters of the Company's underwritten public offering in February 2013. In May 2011, the Company issued 11,500,000 shares of its common stock in an underwritten public offering, including the underwriter's exercise of their full over-allotment option to purchase an additional 1,500,000 shares of common stock. The net proceeds to the Company were $33.7 million, after deducting underwriting fees and offering expenses. During February and March 2012, the Company issued a total of 12,075,000 shares of its common stock in an underwritten public offering, including the underwriter's exercise of their full over-allotment option to purchase an additional 1,575,000 shares of common stock. The net proceeds to the Company were $43.4 million, after deducting underwriting fees and offering expenses. In February 2013, the Company issued 13,800,000 shares of its common stock in an underwritten public offering, including the underwriter's exercise of their full over-allotment option to purchase an additional 1,800,000 shares of common stock. The net proceeds to the Company were $97.0 million, after deducting underwriting fees and offering expenses. Convertible Preferred Stock At December 31, 2012, the Company had authorized 3,000,000 shares of preferred stock all of which have been designated Class C Preferred Stock including 350,000 shares which have been designated Series C-1 Junior Participating Cumulative Preferred Stock (the "Series C-1 Preferred Stock"). Shareholder Rights Plan The Company's Board has adopted a Shareholder Rights Plan, as set forth in the Shareholder Rights Agreement, as amended, between the Company and Computershare Trust Company, N.A., as Rights Agent (the "Rights Agreement"). Pursuant to the terms of the Rights Agreement, the Board declared a dividend distribution of one Preferred Stock Purchase Right (a "Right") for each outstanding share of the Company's common stock. Each Right, which expires in November 2014, entitles their holder to purchase from the Company one ten-thousandth of a share (a "Unit") of Series C-1 Preferred Stock at a cash exercise price of $35.00 per Unit, subject to adjustment. The Rights will trade separately from the common stock and will become exercisable only when a person or group has acquired 15% or more of the outstanding common stock or upon the commencement by a person or group of a tender offer that would result in such person or group acquiring 15% or more of the outstanding common stock other than as a result of repurchases of stock by the Company or certain inadvertent actions by a shareholder. In the event a person or group acquires 15% or more of the outstanding common stock each holder of a Right (except for any such person or group) would be entitled to receive upon exercise sufficient Units of Series C-1 Preferred Stock to equal a value of two times the exercise price of the Right. In the event the Company is acquired in a merger or other business combination transaction or if 50% or more of the Company's assets or earning power is sold, each holder of a Right (except for any such person or group described above) would receive upon exercise common stock of the acquiring company with a value equal to two times the exercise price of the Right.
