Issuance of common stock

On June 8, 2012, the Company issued 400,000 shares of restricted Common Stock pursuant to the Company’s 2006 Equity Incentive Plan (defined below) as compensation to its non-employee directors. The fair value of the shares was $0.265 per share, the closing price of the Company’s Common Stock on June 12, 2012, the date of the grant. The shares vested on the date of grant.

In July 2012, the Company issued 9,771,223 shares of its Common Stock to LDK Europe, a wholly-owned subsidiary of LDK, and 1,814,655 of its Common Stock to each of the two founders of SGT pursuant to the SGT Acquisition and Stock Purchase Agreement as part of an aggregate purchase price of 5.0 million Euros (approximately $6.3 million in U.S. Dollars at June 30, 2012).

Issuance of warrants to purchase common stock

On February 15, 2012, the Company’s Board of Directors approved the issuance of a warrant agreement for Cathay General Bancorp to purchase 300,000 shares of the Company’s Common Stock at $0.75 per share related to the credit facility entered into with Cathay Bank for an original aggregate principal amount of $9.0 million. The fair value of $0.29 per share was determined using the Black-Scholes-Merton model. Assumptions used in calculating fair value were as follows: a risk free interest rate of .38%, expected volatility of 103%, zero expected dividend yield, and an expected term of 3 years. The warrant expires on February 15, 2015 and is exercisable anytime within that period for an exercise price of $0.75 per share. The value of the warrant was amortized over the remaining term of the associated credit facility through December 31, 2012. For the three month period ended June 30, 2013 and 2012, zero and $37,000 was amortized to interest expense. For the six month period ended June 30, 2013 and 2012, zero and $55,000 was amortized to interest expense.
