At inception, we evaluated whether the milestone conditions had been achieved and if it was probable that a significant revenue reversal would not occur before recognizing the associated revenue and determined that these milestone payments were not within our control or the licensee’s control, such as regulatory approvals, and were not considered probable of being achieved until those approvals were received.

Accordingly, at inception, we fully constrained the $26.0 million of event-based milestone payments until such time that it is probable that significant revenue reversal would not occur. The sales-based milestone payments and other royalty-based payments are based on a level of sales for which the license is deemed to be the predominant item to which the royalties relate.
