Concentration of Business Risk [Abstract]

5. Concentration of Business Risk

We have historically funded our operations from collaborations with corporate partners and a relatively small number of partners have accounted for a significant percentage of our revenue. Revenue from significant partners, which is defined as ten percent or more of our total revenue, was as follows:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2014		2013		2014		2013
Partner A		72%		25%		59%		16%
Partner B		12%		48%		9%		22%
Partner C		1%		18%		15%		21%
Partner D		0%		0%		0%		31%

Contract receivables from two significant partners comprised approximately 94 percent of our contract receivables at September 30, 2014. Contract receivables from three significant partners comprised approximately 91 percent of our contract receivables at December 31, 2013.
