Collaboration agreements and other contractual arrangements [Abstract]
Collaboration Agreements and Other Contractual Arrangements	COLLABORATION AGREEMENTS AND OTHER CONTRACTUAL ARRANGEMENTS On May 15, 2015, we entered into a development agreement wherein we transferred the ownership rights to two pharmaceutical products to a clinical stage development company to fund and conduct development activities for the products. We do not expect to incur any expense related to the development of either product. If the products are approved by the FDA, we will execute a buy-back agreement to purchase each product for a multiple of the development costs incurred. Based on the initial development budget for each product, the estimated purchase price for both products is approximately $78.0 million. If development costs exceed the initial budgeted amounts, the purchase price will increase but will not exceed approximately $105.0 million. If the products are approved by the FDA and we purchase the products, we estimate the acquisitions will occur in 2019. During the year ended December 31, 2016, we added three additional products to the May 15, 2015 development agreement that are subject to similar buy-back terms if the products are approved by the FDA. We did not receive any consideration from the clinical stage development company, nor do we expect to incur any expense related to the development of the additional products. The estimated purchase price for these additional products, based on the initial development budget, is approximately $126.0 million. If development costs exceed the initial budgeted amounts, the purchase price will increase, but will not exceed approximately $174.0 million. If the products are approved by the FDA and we purchase the products, we estimate that one of the acquisitions will occur in 2019 and two of the acquisitions will occur in 2021. There can be no assurance that any such products will be approved by the FDA on the anticipated schedule or at all. On May 1, 2015, we entered into an agreement with a clinical stage biotechnology company for the development of two specialty pharmaceutical products. We paid $18.0 million for an option to acquire the two products, which we reported in research and development expense. On March 1, 2016, we exercised the purchase option to acquire both products. We will make additional payments if we obtain regulatory approval and achieve certain sales milestones, and these contingent milestone payments could total $30.0 million in aggregate. We will also be obligated to make certain royalty payments over periods ranging from seven to ten years from the launch of each product. Refer to the Development-Stage Rx Products acquisition in Note 2 for additional information regarding the acquisition. In addition, during the three months ended April 1, 2017, we recorded an impairment of these assets and a corresponding reduction in the liability for the contingent milestone payments, which are further discussed in Notes 3 and 6, respectively.”
