License Agreements	10. License Agreements Grupo Ferrer Internacional, S.A. On October 5, 2011, we and Ferrer entered into the Ferrer Agreement to commercialize ADASUVE in the Ferrer Territories (Europe, Latin America, the Commonwealth of Independent States countries, the Middle East and North Africa countries, Korea, Philippines and Thailand). Under the terms of the Ferrer Agreement, we received an upfront cash payment of $10,000,000, of which $5,000,000 was paid to the former stockholders of Allegro. The Ferrer Agreement provided for up to an additional $51,000,000 in additional milestone payments, contingent on approval of the EU Marketing Authorization Application, or MAA, certain individual country commercial sales initiations and royalty payments based on cumulative net sales targets in the Ferrer Territories. The MAA was submitted to the European Medicines Agency, or EMA, and was approved in February 2013 by the European Commission, or the EC. Ferrer has the exclusive rights to commercialize the product in the Ferrer Territories. We supply ADASUVE to Ferrer for all of its commercial sales, and receive a specified per-unit transfer price paid in Euros. Either party may terminate the Ferrer Agreement for the other party’s uncured material breach or bankruptcy. The Ferrer Agreement continues in effect on a country-by-country basis until the later of the last to expire patent covering ADASUVE in such country or 12 years after first commercial sale. The Ferrer Agreement is subject to earlier termination in the event the parties mutually agree, by a party in the event of an uncured material breach by the other party or upon the bankruptcy or insolvency of either party. In October 2014, we entered into an amendment to the Ferrer Agreement. We and Ferrer agreed to eliminate certain individual country commercial sales initiation milestone payments in exchange for Ferrer’s purchase of 2,000,000 shares of our common stock for $4.00 per share for a total of $8,000,000, which reflected a premium on the fair value of our common stock of approximately $2,400,000. In January 2015, we paid the former shareholders of Allegro $865,000 related to this stock sale. In June 2015, we entered into another amendment to the Ferrer Agreement. We and Ferrer agreed to: (i) transfer ownership of the MAA to Ferrer, whereby Ferrer becomes responsible for all post-approval requirements of the MAA, including the post-authorization safety study, the drug utilization study and the Phase 3 clinical trial for adolescents and all other related regulatory activities and costs associated with the ADASUVE MAA, (ii) provide Ferrer an option to manufacture ADASUVE in the Ferrer Territories as well as for use by us in territories other than the U.S., Canada, China, Hong Kong, Taiwan and Macao, and if Ferrer does not exercise this option, we have the right to assign the ADASUVE manufacturing right to a third party, subject to Ferrer’s written consent, not to be unreasonably withheld, (iii) eliminate the remaining milestones related to first commercial sales in selected countries, and (iv) provide Ferrer with the right to access technology and develop a Staccato product of their choice to commercialize in the Ferrer Territories, with Ferrer paying a fixed royalty percentage on all sales of new Staccato products developed by Ferrer. The transfer of the MAA for ADASUVE to Ferrer was completed in August 2015. We evaluated whether the delivered elements under the Ferrer Agreement, as amended, have value on a stand-alone basis and allocated revenue to the identified units of accounting based on relative fair value. We determined that the license and the development and regulatory services are a single unit of accounting as the licenses were determined not to have stand-alone value. We have begun to deliver all elements of the arrangement and are recognizing the $10,000,000 upfront payment as revenue ratably over the estimated performance period of the agreement of four years. The $1,452,000 and $2,400,000 premiums received from the sales of common stock to Ferrer are additional consideration received pursuant to the Ferrer Agreement and does not pertain to a separate deliverable or element of the arrangement, and thus is being deferred and recognized as revenue in a manner consistent with the $10,000,000 upfront payment. The Ferrer Agreement, as amended, provides for us to receive up to $40,000,000 of additional payments related to cumulative net sales targets in the Ferrer Territories. The cumulative net sales targets will be recognized as royalty revenue when each target is earned and payable to us. We believe each of these milestones is substantive as there is uncertainty that the milestones will be met, the milestone can only be achieved as a result of our past performance and the achievement of the milestone will result in additional payment to us. In January 2014, we recognized revenue in the amount of $1,000,000 from a milestone payment for the first product sale in Spain, of which $250,000 was paid to the former stockholders of Allegro (Refer to Note 3 – Summary of Significant Accounting Policies). We recognized $712,000 and $612,000 of revenue related to the Ferrer Agreement, as amended, in the three months ended March 31, 2016 and 2015, respectively. At March 31, 2016 we had deferred revenue of $2,136,000 related to the Ferrer Agreement, as amended. Teva Pharmaceuticals USA, Inc. In May 2013, we entered into the Teva Agreement to provide Teva with an exclusive license to develop and commercialize ADASUVE in the United States. In February 2016, we entered into the Teva Amendment which is intended to allow us to continue to provide ADASUVE product to patients and health care providers and provides for (i) the transfer of the New Drug Application, or NDA, and related regulatory filings for ADASUVE to us and the assumption of responsibility by us for all regulatory activities related to ADASUVE in the U.S. as soon as practicable; (ii) an exclusive license of Teva intellectual property with respect to ADASUVE, which intellectual property will be assigned to us in connection with a change of control or an exclusive license to ADASUVE in the U.S. from us to a third party; (iii) our undertaking of responsibility for the ADASUVE United States Phase 4 study, product pharmacovigilance, medical services, and REMS compliance, either through Teva’s vendors or a vendor otherwise selected by us; (iv) the transfer from Teva of existing supplies of ADASUVE as well as all commercial, medical and academic materials, documents and relationships; (v) our right to sell Teva-labeled products in accordance with all applicable laws and Teva policies; (vi) the satisfaction and termination of all payment obligations of the parties with respect to the commercialization of ADASUVE except with respect to the Amended Teva Note and our issuance of 2,172,886 shares of our common stock to Teva; and (vii) a mutual release between the parties with respect to claims under the Teva Agreement.
