Subsequent Events [Abstract]
SUBSEQUENT EVENT	6. SUBSEQUENT EVENT In April 2019, we entered into an operating lease agreement for office space located at 3 Sylvan Way, Parsippany, New Jersey. The initial term of the lease is 11 years with an option to extend for an additional five years and a one-time option to terminate the lease without cause as of the 103^rd month anniversary of the commencement date of the lease. We have not yet occupied the space as it is being renovated for our use. The lease term commences upon the earlier of the date of completion of the construction work or the date upon which we occupy and use the space for its intended purpose. Since we do not yet have control of the space, as defined by Topic 842, during the construction period and do not expect to gain control of the space until on or near the construction completion date, we will not record a right-of-use asset and corresponding lease liability until we occupy the space, which we expect to occur by the end of the third quarter of 2019. Upon the commencement of the lease, the aggregate minimum future lease payments for the initial lease term is approximately $3,700,000, net of a seven-month rent abatement period. Under the lease, we are also obligated to pay certain variable expenses separately from the base rent, including electricity and common area maintenance. Such costs will be expensed in the period they are incurred.
