Shell and Raízen
Prior to June 2011 Shell was considered a related party due to the size of its ownership interest. As discussed in Note 3, “Collaborative Research and Development Agreements,” Shell transferred full ownership of our common stock to Raízen, Shell's joint venture with Cosan in Brazil. Based on our analysis and effective as of July 1, 2011, Shell was no longer considered a related party. Before June 30, 2011, related party receivables, related party deferred revenue, and related party collaboration research and development revenue were primarily comprised of transactions under our five-year Shell Research Agreement (replaced by the New Shell Agreement effective as of August 31, 2012) and the Shell License Agreement. The revenues earned from Shell are included in the collaborative research and development line on our condensed consolidated statement of operations. Collaborative research and development revenue received from Shell accounted for 51%, 51% and 62% of our revenues for the years ended December 31, 2012, 2011 and 2010, respectively. Collaborative research and development revenue received from Shell accounted for zero and 45% of our revenues for the three months ended March 31, 2013 and 2012, respectively.
At the time of the transfer, Raízen owned 5.6 million shares of our common stock and had the right to appoint a member to our board of directors. This right terminated upon the termination of the Shell Research Agreement effective August 31, 2012. In September 2011, we entered into a joint development agreement with Raízen to develop an improved first generation ethanol process with enhanced economics. There has been no material financial activity with Raízen through March 31, 2013 and work under this joint development agreement has been completed and we do not expect this project to continue.
Raízen has exclusive rights to market and use CodeXyme® in Brazil. We are engaged in discussions with Raízen about obtaining rights to market CodeXyme® to all ethanol producers in Brazil. Raízen will remain a target customer for CodeXyme® should Raízen decide to build capacity for second generation ethanol in Brazil.
Exela PharmaSci, Inc.
We signed a license agreement with Exela PharmaSci, Inc. (“Exela”) in 2007. A member of our board of directors is also on the board of directors of Exela. Under the terms of the agreement, Exela would pay us a royalty based on their achievement of certain commercial goals.
During the three months ended March 31, 2013 and 2012, we recognized $1.0 million and $150,000 of revenue, respectively, related to this arrangement, shown in our condensed consolidated statement of operations as collaborative research and development revenue. We did not recognize any revenue from Exela prior to 2011. As of March 31, 2013 and December 31, 2012, we had no amounts owed from Exela.
