| Commitments and Contingencies                | 9.Commitments and ContingenciesIn the ordinary course of our business, we enter into agreements with third parties, such as business partners, clinical sites and suppliers, that include usual and customary indemnification provisions. We generally reciprocally agree to indemnify, hold harmless and reimburse indemnified parties for losses suffered or incurred with respect to products or product candidates, use of such products or other actions taken or omitted by the parties. The maximum potential amount of future payments we could be required to make under these indemnification provisions is generally not limited. We have not incurred material costs to defend lawsuits or settle claims related to these provisions. As a result, the estimated fair value of liabilities relating to indemnification provisions is minimal. We have no liabilities recorded for these provisions as of June 30, 2013.Progenics is a party to a proceeding brought by a former employee complaining that the Company violated the anti-retaliation provisions of the federal Sarbanes-Oxley law by terminating the former employee.  The Company believes the former employee's claims are without merit and is contesting the matter vigorously.  The federal District Court hearing the case recently issued an order denying our motion for summary judgment dismissing the former employee's complaint, which makes it likely that the proceeding will continue to trial. Given the inherent uncertainty attendant to the proceeding, it is not possible at this time to estimate the likelihood or potential magnitude of any outcome, and we have accordingly not recorded any associated liability in these interim Consolidated Financial Statements. |
