Under certain conditions, the Collaboration Agreement may be terminated by either party, in which case the Company would receive all rights to the regulatory filings related to Iclusig at our request, and the licenses granted to Otsuka would be terminated. The nonrefundable upfront cash payment has been recorded as deferred revenue on the Company's balance sheet and is being recognized as revenue on a straight-line basis over the estimated term (currently estimated to extend through 2029), beginning at the point at which the Company began to provide all elements included in the Collaboration Agreement, which occurred in April 2015.
