Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets	NOTE 4. GOODWILL AND INTANGIBLE ASSETS In the fourth quarter of 2014, the Company entered into a License Agreement with CureTech, pursuant to which it licensed exclusive worldwide rights to CureTech’s late-stage clinical molecule, MDV9300. The Company concluded that the in-license transaction is an acquisition of a business in accordance with FASB Accounting Standards Codification, or ASC, 805-10, “Business Combinations.” The transaction resulted in identifiable intangible assets of $101.0 million consisting entirely of in-process research and development, or IPR&D, and goodwill of $10.0 million. The Company accounts for IPR&D as indefinite-lived intangible assets until regulatory approval or discontinuation at which time the Company evaluates impairment, converts the carrying value into a definite-lived intangible asset and determines the economic life for amortization purposes. The Company assesses the impairment of intangible assets and goodwill on an annual basis or more frequently whenever events or changes in circumstances may indicate that the carrying value might not be recoverable. The Company applies the rules in ASU No. 2011-08, “Testing Goodwill for Impairment,” which amends the rules for testing goodwill for impairment by allowing an entity the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events or circumstances, an entity determines it is more likely than not that the fair value of a reporting unit is greater than its carrying amount, then performing the two-step impairment test is unnecessary. The Company applies the rules in ASU No. 2012-02, “Testing Indefinite-Lived Intangibles Assets for Impairment,” which provides entities with an option to perform a qualitative assessment of indefinite-lived intangible assets other than goodwill for impairment to determine if additional impairment testing is necessary. The Company evaluated its goodwill and indefinite-lived intangible assets utilizing the simplified approach as of June 30, 2015. The Company determined that its goodwill and indefinite-lived intangible assets were not impaired at June 30, 2015. The Company was not required to perform the two-step quantitative impairment test.

The entire disclosure for the aggregate amount of goodwill and a description of intangible assets, which may include (a) for amortizable intangible assets (also referred to as finite-lived intangible assets), the carrying amount, the amount of any significant residual value, and the weighted-average amortization period, (b) for intangible assets not subject to amortization (also referred to as indefinite-lived intangible assets), the carrying amount, and (c) the amount of research and development assets acquired and written off in the period, including the line item in the income statement in which the amounts written off are aggregated, if not readily apparent from the income statement. Also discloses (a) for amortizable intangibles assets in total and by major class, the gross carrying amount and accumulated amortization, the total amortization expense for the period, and the estimated aggregate amortization expense for each of the five succeeding fiscal years, (b) for intangible assets not subject to amortization the carrying amount in total and by major class, and (c) for goodwill, in total and for each reportable segment, the changes in the carrying amount of goodwill during the period (including the aggregate amount of goodwill acquired, the aggregate amount of impairment losses recognized, and the amount of goodwill included in the gain (loss) on disposal of a reporting unit). If any part of goodwill has not been allocated to a reportable segment, discloses the unallocated amount and the reasons for not allocating. For each impairment loss recognized related to an intangible asset (excluding goodwill), discloses: (a) a description of the impaired intangible asset and the facts and circumstances leading to the impairment, (b) the amount of the impairment loss and the method for determining fair value, (c) the caption in the income statement or the statement of activities in which the impairment loss is aggregated, and (d) the segment in which the impaired intangible asset is reported. For each goodwill impairment loss recognized, discloses: (a) a description of the facts and circumstances leading to the impairment, (b) the amount of the impairment loss and the method of determining the fair value of the associated reporting unit, and (c) if a recognized impairment loss is an estimate not finalized and the reasons why the estimate is not final. May also disclose the nature and amount of any significant adjustments made to a previous estimate of an impairment loss.
