Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Litigation - The Company may be subject to legal proceedings and claims which arise in the ordinary course of its business. In the Company's opinion, the ultimate resolution of these matters is not expected to have a material effect on its consolidated financial statements. The Company records a liability in its consolidated financial statements for these matters when a loss is known or considered probable and the amount can be reasonably estimated. The Company reviews these estimates each accounting period as additional information is known and adjusts the loss provision when appropriate. If a matter is both probable to result in a liability and the amounts of loss can be reasonably estimated, the Company estimates and discloses the possible loss or range of loss to the extent necessary to make the consolidated financial statements not misleading. If the loss is not probable or cannot be reasonably estimated, a liability is not recorded in its consolidated financial statements. In November 2016, the Company received notice that in October 2016, Ipsen had initiated arbitration proceedings against the Company in the International Chamber of Commerce’s International Court of Arbitration. Ipsen’s Request for Arbitration alleged that the Company breached various provisions of the License Agreement concerning abaloparatide, including with regard to Ipsen's right to co-promote abaloparatide in France and a license from the Company with respect to Japan. Ipsen is seeking declaratory relief, compliance with the License Agreement, damages, costs and fees as a result of the purported breaches, and has alleged that the monetary value of these claims is approximately €50 million. In January 2017, the Company submitted an Answer denying Ipsen’s claims and alleging counterclaims against Ipsen for breach of the License Agreement and other declaratory judgment. The Company asserted, among other things, that Ipsen's claimed rights to co-promote abaloparatide in France and to a license from the Company with respect to Japan have permanently expired, and that Ipsen has breached the License Agreement by, among other things, allowing certain patents to expire and by purporting to license to a third party certain manufacturing and other rights that the Company contends Ipsen exclusively licensed to the Company. The Company is seeking dismissal of Ipsen’s claims, as well as declaratory relief, compliance with the License Agreement, and other damages, costs and fees to be determined by the Arbitral Tribunal. In February 2017, Ipsen submitted a Reply denying the Company's counterclaims and alleging that the Company is precluded from asserting them. Given that this matter is at a preliminary stage, the Company cannot predict or assess the likely outcome of these proceedings. Manufacturing Agreements - In June 2016, the Company entered into a supply agreement with Ypsomed AG (“Ypsomed”), pursuant to which Ypsomed agreed to supply commercial and clinical supplies of a disposable pen injection device (the “Device”) customized for subcutaneous injection of TYMLOS. The Company agreed to purchase a minimum number of Devices at prices per Device that decrease with an increase in quantity supplied. In addition, the Company agreed to make milestone payments for Ypsomed’s capital developments in connection with the initiation of the commercial supply of the Device and to pay a one-time capacity fee. All costs and payments under the agreement are delineated in Swiss Francs. The agreement has an initial term of three years from the earlier of the date of delivery of the first commercial Devices for regulatory approval and June 1, 2017, after which it automatically renews for two-year terms until terminated. The Company agreed to purchase the Device subject to certain minimum annual quantity requirements under the agreement. During the initial term of the agreement, the Company estimates that it will be obligated to make total minimum payments to Ypsomed of approximately CHF 3.9 million ($4.0 million) in the aggregate, including the milestone payments and one-time capacity fee. In June 2016, the Company entered into a commercial supply agreement with Vetter Pharma International, GmbH (“Vetter”), pursuant to which Vetter agreed to formulate the finished TYMLOS drug product containing the active pharmaceutical ingredient (“API”) of TYMLOS, to fill cartridges with the drug product, to assemble the pen delivery device, and to package and label the pen for commercial distribution. The Company agreed to purchase the cartridges and pens in specified batch sizes at a price per unit. For labeling and packaging services, the Company agreed to pay a per unit price dependent upon the number of pens loaded with cartridges that are labeled and packaged. These prices are subject to an annual price adjustment. The agreement has an initial term of five years, which began on January 1, 2016, after which, it automatically renews for two-year terms unless either party provides notice of non-renewal two years before the end of the then current term. In July 2016, the Company entered into a manufacturing services agreement with Polypeptide Laboratories Holding AB ("PPL"), as successor-in-interest to Lonza Group Ltd., pursuant to which PPL agreed to manufacture the commercial and clinical supplies of the API for TYMLOS. The Company agreed to purchase the API in batches at a price per gram in euros, subject to an annual increase by PPL. The Company also agreed to purchase a minimum number of batches annually. The agreement has an initial term of six years, after which, it automatically renews for three-year terms unless either party provides notice of non-renewal 24 months before the end of the then-current term.
