Collaborations and Other Agreements

Allergan Inc.

In August 2009, pursuant to an agreement with Allergan Inc. (“Allergan”), the Company granted Allergan a worldwide exclusive license to develop and commercialize certain drug candidates for the treatment and prevention of ocular diseases. Allergan is responsible for the research, development, manufacturing and commercialization of any products resulting from the license. The Company received a non-refundable upfront payment of $10 million upon execution of the contract in 2009 and is entitled to receive up to an aggregate of $13 million in milestone payments upon the achievement of certain commercial milestones or patents granted to the Company by the United States Patent and Trademark Office that cover a product licensed to Allergan.

At the inception of the agreement, the Company recognized revenue from the upfront license payment because, based on the stage of development of the licensed product delivered and the development capabilities of Allergan, the Company determined that the license had standalone value. Through December 31, 2014, none of the milestones had been achieved and, as such, the Company has not recognized milestone-related revenues from the collaboration agreement with Allergan.

Daiichi Sankyo Co., Ltd.

In May 2011, the Company entered into an agreement with Daiichi Sankyo Co., Ltd. (“Daiichi Sankyo”), under which the Company will use its proprietary Anticalin^® scaffold technology to identify drug candidates against certain targets selected by Daiichi Sankyo, with further development and commercialization performed by Daiichi Sankyo. For any targets selected by Daiichi Sankyo, the Company granted an exclusive, worldwide license for the research, development and commercialization of drug candidates identified by the Company. In March 2013 and June 2014, the Company transferred further development responsibility for the two collaboration projects to Daiichi Sankyo.

Upon execution of the agreement, Daiichi Sankyo paid the Company a non-refundable upfront payment in the amount of $10.1 million in consideration for the licenses, and for each licensed product the Company is entitled to receive potential milestone payments of $98.7 million, plus royalties on the commercial sales of any commercial products. The total milestones are categorized as follows: research milestones of $2.8 million; development milestones of $40.5 million; commercial milestones of $54.5 million; additional diagnostic milestones of $0.9 million. At the inception of the agreement, these milestones were determined to be substantive as there was substantial uncertainty the milestones would be achieved, they would require substantial performance from the entity, and the consideration was reasonable relative to other deliverables. The agreement includes provisions for the Company to provide research services funded by Daiichi Sankyo at agreed upon full-time employee rates during the initial identification and research period.

In accordance with the guidance in ASC 605-25, the Company identified the licenses and research funding as deliverables at the inception of the arrangement. The Company has determined that the licenses and research services provided by the Company represent one unit of accounting because, based on the stage of development of the licensed product the research services provided by the Company to identify drug candidates using the Company’s proprietary Anticalin^® technology against Daiichi Sankyo’s selected targets were necessary before the licenses would have any standalone value. Therefore, the total arrangement consideration was recognized over the estimated period of substantial involvement, which was determined to be the period during which the Company was required to provide research services to discover drug candidates against targets identified. The Company estimated that this period would be approximately two years. For the year ended December 31, 2014, the Company recognized $3.0 million in revenues related to the Daiichi Sankyo collaboration, of which $2.3 million related to the achievement of milestones. For the year ended December 31, 2013, the Company recognized $5.6 million in revenues, of which $1.1 million related to the achievement of milestones.

The milestone payments in 2014 are based on successful in vitro and in vivo studies and for the initiation on a toxicity study in non-human primates. The milestone payments in 2013 resulted from the achievement of a success milestone, the hand-over of a collaboration project to Daiichi Sankyo. The milestones could not be achieved solely upon the passage of time. For revenue recognition purposes, management determined these milestones to be substantive in accordance with applicable accounting guidance related to milestone revenue. Substantive uncertainty existed at the inception of the arrangements as to whether the milestones would be achieved because of the numerous variables, such as the high rate of failure inherent in research and development activities and the uncertainty involved with obtaining regulatory approval. Therefore, each of the milestone payments were recognized in their entirety as revenues during the respective years ended December 31, 2014 and 2013 in which they were received.

Sanofi-Aventis and Sanofi-Pasteur

In September 2010, the Company entered into an agreement with Sanofi-Aventis and Sanofi Pasteur (together, “Sanofi”), under which the Company agreed to apply its proprietary Anticalin^® technology to identify drug candidates against certain targets selected by Sanofi, with further development and commercialization performed by Sanofi. The agreement included the initial identification of two targets by Sanofi, with options to select up to four additional targets. For any targets selected by Sanofi, the Company granted an exclusive, worldwide license for the research, development and commercialization of drug candidates identified by the Company In addition to the two initial targets selected by Sanofi, Sanofi exercised one of the four options and received a license. The remaining three options expired unexercised.

Upon execution of the agreement, Sanofi paid the Company an upfront payment of $4.9 million in consideration for licenses on the first two targets and options to select an additional four licenses on other targets (with each option requiring an additional upfront payment upon exercise). Additionally, for each licensed product, the Company is entitled to receive milestone payments up to $55.9 million, plus royalties on the sales of any commercial products. The total milestones are categorized as follows: research milestones of $2.1 million; development milestones of $32.1 million; and commercial milestones of $21.8 million. At the inception of the agreement, these milestones were determined to be substantive because (i) there was substantial uncertainty the milestones would be achieved, (ii) they would require substantial performance from the entity, and (iii) the consideration was reasonable relative to other deliverables. The agreement includes provisions for the Company to provide research services funded by Sanofi at agreed upon full-time employee equivalent rates during the initial identification and research period.

In accordance with the guidance in ASC 605-25, the Company identified the licenses, options to obtain additional licenses and research funding as deliverables at the inception of the arrangement. The options were considered to be substantive at the inception of the agreement. Factors considered in determining the options were substantive were whether (i) Sanofi could obtain the overall objective of the agreement without exercising any options, (ii) Sanofi was able to obtain value from the initial licenses obtained without exercising any options, (iii) the cost to exercise the options was significant to the total upfront payment of $4.9 million for two licenses and four options, and (iv) exercising the option created additional financial commitments for Sanofi or imposed economic penalties on Sanofi.

The Company has determined that, for each program selected by Sanofi, the license and research services provided by the Company represent one unit of accounting because, based on the stage of development of the licensed product, the research services provided by the Company to identify drug candidates using the Company’s proprietary Anticalin^® technology against Sanofi’s selected targets were necessary before the licenses would have any standalone value.

The estimated selling prices for the licenses in the agreement are the Company’s best estimate of selling price and were determined based on market conditions and entity-specific factors such as considerations of preclinical and clinical testing results and the Company’s pricing practices and pricing objectives. The estimated selling price of research services are the Company’s best estimate of selling price and are determined based on market conditions and entity-specific factors such as internal cost considerations and the Company’s pricing practices and pricing objectives.

At inception, the total arrangement consideration of $8.1 million (which comprises the $4.9 million upfront payment and the expected fees for the research services to be provided under the remainder of the arrangement) was allocated to the deliverables based on the relative selling price method as follows: $3.5 million to the licenses, $1.4 million to the four options to acquire additional licenses and $3.2 million to the estimated research services to be provided. As the license and research services were determined to be one unit of accounting, the consideration allocated to each license is recognized over the period of substantial involvement, which was determined to be the period during which the Company was required to provide research services to discover drug candidates against targets identified, approximately two years. The Company reassessed the estimated term at the end of each reporting period. At the end of 2012, the Company determined that the required research term for one of the initial terms would extend to a period of 40 months, and management updated the estimated required service period to amortize the remaining deferred upfront payment over the new term. Two of the four options expired un-exercised in 2011, and as a result the Company recognized $0.7 million of revenue upon expiration. The option term for the remaining two options was extended to February 2013, and Sanofi exercised one option to obtain an additional license. For the exercised option, the allocated consideration of $0.35 million for the option and the $1.4 million payment of the exercise price were deferred and amortized over the expected required service period of approximately two years. The program covered by the exercised option was terminated in December 2013, and accordingly, the Company recognized the remaining deferred revenue upon termination. The remaining option expired in February 2013 and the allocated consideration of $0.35 million was recognized into revenue at the time of expiration.

For the years ended December 31, 2014 and 2013, the Company recognized $1.4 million and $4.2 million, respectively, related to the Sanofi collaboration. In 2014, $0.9 million was recognized related to the achievement of milestones. The milestone payments in 2014 result from a positive review of a broad range of in vitro, in vivo and chemistry, manufacturing and control (“CMC”) data. No milestones had been achieved through December 31, 2013.

Stelis BioPharma

The Company entered into an agreement with Stelis BioPharma Private Limited (“Stelis”) on November 21, 2013, pursuant to which, the Company collaborates with Stelis in the development of certain Anticalin^® drug candidates, primarily for use in the treatment, palliation or prevention of ophthalmology-related diseases. Both parties may establish a joint venture for further development and commercialization of one or more such products in the future. The Company granted Stelis a royalty-free, co-exclusive license within a specified field. Stelis is responsible for further developing the chosen candidates and taking them through certain development stages and bears all related expenses.

The license granted refers to products (Anticalin^® proteins) which have already been researched and developed by the Company independently before the arrangement with Stelis.

No payments have been received under this agreement, and thus, no revenues have been recognized.

Cadila Healthcare Limited

On October 7, 2013, the Company entered into an agreement with Cadila Healthcare Limited (“Zydus”), under which the Company granted to Zydus an exclusive, royalty-bearing license to use, sell, and import/export certain Anticalin^® drug products, including the right to grant sublicenses in a specified territory. Zydus also received a co-exclusive royalty-free license to research, develop and produce a product in the specified territory as well as to conduct research and manufacture a product in specified field, as long as such activities are solely the development or commercialization in Zydus’ territory as defined in the agreement. The Company received under the agreement a non-exclusive, royalty-free, world-wide license to exploit know-how and intellectual property that was made available to Zydus before October 7, 2013. Both parties agreed upon several milestone payments as well as a sharing of out-licensing revenue.

No payments have been received under this agreement, and thus, no revenues have been recognized.

Other Arrangement

The Company entered into a materials transfer agreement, which is effective as of January 14, 2013. Under this arrangement the partner tests certain Company Anticalin^® proteins with certain proprietary materiel, conducts certain purification and characterization studies on the resulting combined products and subsequent preclinical studies. The Company produces and supplies Anticalin proteins and receives research reports from the partner. Each party is otherwise responsible for its own costs and expenses. The Company recognized research and development services revenue of $138,091 in the year ended December 31, 2013 under this arrangement. No revenues were recognized under this agreement for the year ended December 31, 2014.
