Collaboration arrangement	7. Collaboration arrangement Sanofi License Agreement and Sanofi Supply Agreement As disclosed in Note 1 under Basis of Presentation, the Company entered into a license and collaboration agreement with Sanofi which was terminated effective April 4, 2016. On April 5, 2016 the Company assumed responsibility for the worldwide development and commercialization of Afrezza from Sanofi. Under terms of the transition agreement, Sanofi continued to fulfill orders for Afrezza in the United States until the Company began distributing MannKind-branded product to major wholesalers during the week of July 25, 2016. As previously disclosed, worldwide profits and losses incurred by the Company and Sanofi that are specifically attributable or related to the development, regulatory filings, manufacturing, or commercialization of Afrezza, are shared 65% by Sanofi and 35% by the Company until Sanofi ceases to distribute Afrezza. The Company analyzed the agreements entered into with Sanofi to determine whether the consideration, or a portion thereof, could be recognized as revenue. Revenue is recognized when there is persuasive evidence that an arrangement exists, delivery has occurred or services have been rendered, the price is fixed or determinable and collection is reasonably assured. In addition, revenue arrangements with multiple elements are divided into separate units of accounting if certain criteria are met, including whether the delivered element has stand-alone value to the customer. When deliverables are separable, consideration received is allocated to the separate units of accounting based on the relative selling price of each deliverable and the appropriate revenue recognition principles are applied to each unit. The assessment of multiple element arrangements requires judgment in order to determine the appropriate units of accounting and the points in time that, or periods over which, revenue should be recognized. Under the terms of the Sanofi License Agreement, Sanofi Supply Agreement and the Sanofi Loan Facility the Company determined that the arrangement contained significant deliverables including (i) licenses to develop and commercialize Afrezza and to use the Company’s trademarks, (ii) development activities, and (iii) manufacture and supply services for Afrezza. Due to the proprietary nature of the manufacturing services being provided by the Company, the Company determined that all of the significant deliverables should be combined into a single unit of accounting. The Company believes that the manufacturing services are proprietary due to the fact that since the late 1990’s, the Company has developed proprietary knowledge and patented equipment and tools that are used in the manufacturing process of Afrezza. Due to the complexities of particle formulation and the specialized knowledge and equipment needed to handle the Afrezza powder, neither Sanofi nor any third-party contract manufacturing organization currently possesses the capability of manufacturing Afrezza. In order for revenue to be recognized, the seller’s price to the buyer must be fixed and determinable. Given that as of June 30, 2016 the Company did not have the ability to estimate the amount of costs that would potentially be incurred under the profit and loss share provision related to the Sanofi License Agreement and the Sanofi Supply Agreement, the Company believes this requirement for revenue recognition has not been met. As such, the Company did not recognize any revenue pursuant to the Sanofi License Agreement or the Sanofi Supply Agreement for the three months ended June 30, 2016. The Company has recorded the $150.0 million up-front payment and $50.0 million from milestone payments as deferred payments from collaboration. In addition, as of June 30, 2016 the Company has recorded $17.7 million in Afrezza product shipments to Sanofi recorded as deferred sales from collaboration and recorded $22.7 million as deferred costs from collaboration. Deferred costs represent the costs directly related to the collaboration, not to exceed the amount of deferred sales, for which recognition of revenue has been deferred. During the quarter ended June 30, 2016, the Company’s portion of the profit sharing was $0.3 million, which resulted in the reclassification from current deferred payments from collaboration to Sanofi loan facility and profit/loss share obligation to reflect amounts owed to Sanofi. Sanofi Loan Facility On September 23, 2014, the Company entered into the Sanofi Loan Facility, consisting of a senior secured revolving promissory note and a guaranty and security agreement (the “Security Agreement”) with an affiliate of Sanofi which provides the Company with a secured loan facility of up to $175.0 million to fund the Company’s share of net losses under the Sanofi License Agreement. In the event of certain future defaults under the Sanofi Loan facility agreement for which the Company is not able to obtain waivers, the lender under the Sanofi Loan Facility may accelerate all of the Company’s repayment obligations, and take control of the Company’s pledged assets, potentially requiring the Company to renegotiate the terms of its indebtedness on terms less favorable to the Company, or to immediately cease operations. The obligations of the Company under the Sanofi Loan Facility are guaranteed by the Company’s wholly-owned subsidiary, MannKind LLC, and are secured by a first priority security interest in certain insulin inventory located in the United States and any contractual rights and obligations pursuant to which the Company purchases or has purchased such insulin, and a second priority security interest in the Company’s assets that secure the Company’s obligations under the Facility Agreement, as amended. In addition, the Company granted to Sanofi, as additional security for the obligations under the Sanofi Loan Facility, a first priority mortgage on the Company’s facility in Valencia, California, which has a carrying value of $17.6 million as of June 30, 2016. Advances under the Sanofi Loan Facility bear interest at a rate of 8.5% per annum and are payable in-kind and compounded quarterly and added to the outstanding principal balance under the Sanofi Loan Facility. The Company is required to make mandatory prepayments on the outstanding loans under the Sanofi Loan Facility from its share of any profits (as defined in the Sanofi License Agreement) under the Sanofi License Agreement within 30 days of receipt of its share of any such profits. No advances may be made under the Sanofi Loan Agreement if Deerfield has commenced enforcement proceedings in connection with an event of default under the Facility Agreement. The outstanding principal of all loans under the Sanofi Loan Facility, if not prepaid, will become due and payable on September 23, 2024 unless accelerated pursuant to the terms of the Sanofi Loan Facility. Additionally, if the Company sells its Valencia facility, the Company is required to prepay the loans under the Sanofi Loan Facility from the net cash proceeds of the sale within five business days of receipt. The maturity date of September 23, 2024 for repayment of the outstanding principal amount of the loans under the Sanofi Loan Facility is not affected by the termination of the Sanofi License Agreement. The Company’s total cumulative portion of the loss sharing, including interest, was $70.0 million, of which $70.3 million was borrowed under the Sanofi Loan Facility as of June 30, 2016. For the three months ended June 30, 2016, the Company’s portion of the profit sharing was $0.3 million under the Sanofi License Agreement, which is required to be applied as a prepayment against the balance owed under the Sanofi Loan Facility. The total amount owed to Sanofi is $70.0 million, which includes $4.3 million in paid-in-kind interest capitalized as principal. The Sanofi Loan Facility includes customary representations, warranties and covenants by the Company, including restrictions on its ability to incur additional indebtedness, grant certain liens and make certain changes to its organizational documents. Events of default under the Sanofi Loan Facility include: the Company’s failure to timely make payments due under the Sanofi Loan Facility; inaccuracies in the Company’s representations and warranties to the noteholder; the Company’s failure to comply with any of its covenants under any of the Sanofi Loan Facility or certain other related security agreements and documents entered into in connection with the Sanofi Loan Facility, subject to a cure period with respect to most covenants; the Company’s insolvency or the occurrence of certain bankruptcy-related events; and the failure of any material provision under any of the Sanofi Loan Facility or certain other related security agreements and documents entered into in connection with the Sanofi Loan Facility to remain in full force and effect. If one or more events of default occurs and is continuing, Sanofi may terminate its obligation to make advances under the Sanofi Loan Facility, and, if certain specified events of default (including the Company’s failure to timely make payments due under the Sanofi Loan Facility; the Company’s failure to comply with the negative covenants under the Sanofi Loan Facility limiting the Company’s ability to incur additional indebtedness or grant certain liens; the Company’s insolvency or the occurrence of certain bankruptcy-related events; or the failure of any material provision under any of the Sanofi Loan Facility or certain other related security agreements and documents entered into in connection with the Sanofi Loan Facility to remain in full force and effect) occur and are continuing, the noteholder may accelerate all of the Company’s repayment obligations under the Sanofi Loan Facility and otherwise exercise any of its remedies as a secured creditor. There can be no assurance that the noteholder would not choose to exercise these rights in the event such events were to occur.
