Note 9 – Fair Value

During August 2010, DCT and NCR Corporation (“NCR”) entered into (i) Share Purchase Agreement, (ii) Investor Rights Agreement, and (iii) Voting Agreement pursuant to which NCR purchased from DCT 3,861,004 shares of the Company’s common stock for an aggregate purchase price of $4,000,000. Additionally, DCT granted NCR a two-year option (“NCR Option”) to purchase up to an additional $4,000,000 of Common Stock at an exercise price of $1.036 per share, subject to adjustment.

On August 4, 2012, the NCR Option matured without being exercised. On the maturity date, the fair value of the NCR Option was valued deterministically to be zero. As of December 31, 2011, DCT estimated the fair value using the Binomial option pricing model and the following assumptions: 0.12% risk-free interest rate, expected volatility of 198%, expected dividend yield of 0%, and remaining life equal to the remaining contractual life of the option.

Until maturity, DCT’s stock option liability fair value was classified using Level 3 inputs, as unobservable inputs to the valuation methodology are significant to the measurement of the fair value, as defined by ASC 820.

The following table summarizes the changes in Level 3 liabilities measured at fair value on a recurring basis (in thousands):

	As of and for the Years Ended December 31,
	2012			2011
Beginning balance - stock option liability	$	502		$	811
