5. Braeburn License

In December 2012, we entered into a license agreement with Braeburn granting Braeburn exclusive commercialization rights to Probuphine in the United States and Canada. As part of the agreement, we received a non-refundable up-front license fee of $15.75 million (approximately $15.0 million, net of expenses), and will receive a $50.0 million milestone payment upon approval by the FDA of the NDA. We will be eligible to receive up to $130.0 million upon achievement of specified sales milestones and up to $35.0 million in regulatory milestones for additional indications, including chronic pain. We will receive tiered royalties on net sales of Probuphine ranging from the mid-teens to the low twenties. In addition, Apple Tree Partners IV, Braeburn’s parent company, has allocated in excess of $75.0 million to launch, commercialize and continue the development of Probuphine.

We have evaluated the revenue components of this license agreement, which includes multiple elements, to determine whether the components of the arrangement represent separate units of accounting.

We have determined that the non-refundable, up-front license fee of $15.75 million (approximately $15.0 million, net of expenses) and our costs up to the PDUFA date to be one deliverable which will be accounted for as a single unit of accounting. This amount will be recognized on a straight-line basis over the estimated period to reach the PDUFA date and meet the contract deliverables, including the transition of production and supply services of the product to Braeburn. Accordingly, we estimate the revenue recognition period for the up-front payment to be approximately 12 months from the date of this agreement. Accordingly, we will recognize revenue for the up-front payment ratably from December 14, 2012, the date of the agreement, through December 14, 2013 at an amount equal to approximately $1.25 million per month. As of March 31, 2013, we have recognized approximately $4.4 million in license revenue and recorded deferred revenues of $10.6 million related to the up-front payment. Internal and external research and development costs related to this product will be expensed in the period incurred.

Under the license agreement, we will receive a $50.0 million milestone payment from Braeburn within 10 days following the achievement of FDA approval of the product NDA. As such, upon receipt of FDA approval our obligation will be fulfilled. As the milestone payment relates solely to past performance, i.e. FDA approval, we will recognize the $50.0 million regulatory milestone payment from Braeburn on the date of achievement of FDA approval in accordance with the milestone method of revenue recognition. Following FDA approval, we will be reimbursed by Braeburn for any development services and activities performed by us at Braeburn’s request.

The license agreement also provides for a development committee. The duties of the development committee are to periodically report to each other, exchange information, and confer with and review the clinical development of the product and matters pertaining to regulatory approval. The development committee has no authority to approve or direct either party to take action, approve or withhold approval for any plan, budget, timeline or strategies, amend, modify or waive compliance with the license agreement, create new obligations or alter, increase or expand, or waive compliance with the license agreement, create new obligations not specified in the license agreement, or alter, increase or expand, or waive compliance by a party with obligations under the license agreement. The development committee can be disbanded upon mutual agreement of the parties and shall automatically disband six years after the NDA transfer date. Based on the above, we have determined that participation in the development committee is perfunctory and inconsequential, and is not considered a separate deliverable in the license agreement.
