Collaboration agreements and other contractual arrangements [Abstract]
Collaboration Agreements and Other Contractual Arrangements	COLLABORATION AGREEMENTS AND OTHER CONTRACTUAL ARRANGEMENTS In May 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 and 2020. In June 2016, we added an additional product to the May 2015 development agreement that is subject to similar buy-back terms if the product is approved by the FDA. The estimated purchase price for this additional product, based on the initial development budget, is approximately $42.0 million. If development costs exceed the initial budgeted amounts, the purchase price will increase, but will not exceed approximately $57.0 million. If the product is approved by the FDA and we purchase the product, we estimate the acquisition will occur in 2020. There can be no assurance that any such products will be approved by the FDA on the anticipated schedule or at all.
