(1) During the second quarter of 2013, we received a $250,000 exclusive option fee from a prospective partner for the development and marketing of Mast Out®. This payment was recorded as deferred revenue upon receipt. During the third quarter of 2013, this prospective partner decided not to execute a license after its final due diligence. Accordingly, the deferred revenue was recognized during the third quarter of 2013. At the same time, $47,604 in capitalized expenses pertaining to the development of Mast Out® were written off.
