        On November 13, 2012, we entered into an agreement to form a joint venture with Sinopec (Nanjing Jingling). The joint venture involves the construction and operation of a PO/MTBE facility in China. Under the joint venture agreement, we hold a 49% interest in the joint venture and Sinopec holds a 51% interest. Our total equity investment is anticipated to be approximately $90 million, net of reimbursements, and we expect to receive approximately $50 million of license fees from the joint venture. The timing of equity contributions and license fee payments depends on various factors, but the majority are expected to be made over the course of the construction period of the plant (expected to be completed in the second half of 2016). At the end of 2014, cumulative capital contributions were approximately $85 million, net of license fees from the joint venture.
