Stockholders' Equity

(16) Stockholders' Equity

a.  Common Stock

In August 2009, the Company closed on an initial public offering on the NASDAQ Global Select Market of 16,100,000 shares of its common stock at $7.00 per share. Of the shares offered, 5,600,000 new shares were offered by the Company and 10,500,000 existing shares were offered by selling stockholders (which included 2,100,000 shares sold by the selling stockholders pursuant to the exercise of the underwriters' over-allotment option). Total proceeds of the offering to the Company were $36,456, net of underwriting discounts and commissions totaling $2,744.

b.  Preferred Stock

The Company is authorized to issue one million shares of preferred stock with such designations, voting and other rights and preferences as may be determined from time to time by the board of directors. To date, no preferred stock has been issued by the Company.

c.  Warrants

In connection with the Company's initial public offering on the AIM market of the London Stock Exchange on October 3, 2005, the Company sold 33,500,000 units, consisting of one share of the Company's common stock and two redeemable common stock purchase warrants. Also in connection with this initial public offering, the Company issued an option to purchase 1,675,000 units (individually, UPO) at an exercise price of $7.50 per UPO. Each UPO consists of one share of the Company's common stock and two redeemable common stock purchase warrants. All of the Company's warrants had an exercise price of $5.00 per common share and were scheduled to expire on October 3, 2009.

During the year ended June 30, 2008, 699,440 of the warrants issued in connection with the Company's initial public offering were exercised and an additional 100,262 warrants and 50,131 common shares were issued in connection with a cashless exercise of 67,458 UPOs.

During the year ended June 30, 2009, 166,668 of the warrants issued in connection with the Company's initial public offering were exercised and an additional 485,505 warrants and 242,753 common shares were issued in connection with a cashless exercise of 282,128 UPOs. Also during the year ended June 30, 2009, the Company executed a warrant exchange program under which it agreed to exchange 5.5 warrants for one share of the Company's common stock. A total of 19,164,294 warrants were converted to 3,484,417 common shares under this exchange program.

Prior to the expiration date, the Company received exercise notifications from the holders of substantially all of the outstanding warrants and UPOs. The holders of the UPOs exercising their UPOs also immediately exercised the warrants issuable upon the exercise of their UPOs. As a result of all of these exercises, the Company issued 1,775,933 shares of common stock to the former holders of the warrants and UPOs, and no warrants or UPOs remain outstanding at June 30, 2010. The Company received $1,497 in cash with respect to these exercises, and the remainder of the shares were issued on a net, cashless basis. The sales and issuances of shares pursuant to the warrant and UPO exercises were deemed to be exempt from registration under the Securities Act of 1933 by virtue of Section 4(2) pertaining to private offers and sales or Regulation S pertaining to foreign offers and sales.

The Company has accounted for all warrant transactions as a component of stockholders' equity.

d.  Treasury Stock

In December 2008, the Company's board of directors approved a share repurchase program that authorized the Company to repurchase up to $25,000 of the Company's common stock during the ensuing six months. The program did not obligate the Company to acquire any particular amount of shares. 1,000 shares were repurchased at $4.00 per share under this program.

In connection with the Company's acquisition of approximately 81% of Solsil in February 2008, 562,867 of the 5,628,657 shares issued to the former shareholders and optionholders of Solsil were placed into escrow pending the attainment of certain milestones. In April 2008, 281,430 of these escrow shares were released based on the satisfaction of certain conditions. Upon expiration of the escrow period in February 2011, the remaining 281,437 escrow shares were returned to the Company and are now included in treasury stock at cost, which is equal to their par value.
