SUBSEQUENT EVENT
SUBSEQUENT EVENT	15. SUBSEQUENT EVENT         In light of projected reduced operational demands as a result of the Collaboration Agreement with Janssen, on March 3, 2015, we announced an organizational resizing to reduce our workforce from 39 to 21 positions, representing a reduction of approximately 46% of our workforce. We expect the majority of the reduction in our workforce to be completed by the end of the third quarter of 2015. In connection with the resizing, we anticipate incurring aggregate restructuring charges of approximately $1,900,000, of which approximately $1,500,000 is expected be paid in cash during 2015. The aggregate projected restructuring charges represent one-time termination benefits, comprised principally of severance, benefit continuation costs, outplacement services and non-cash stock-based compensation expense associated with the elimination of 18 positions. The majority of these charges are expected to be recognized in the first half of 2015. We may incur other charges and will record these expenses in the appropriate period as they are determined.
