6. Leases

In February 2016, the FASB issued ASU No. 2016-02, Leases. The new standard establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases are classified as either finance or operating, with classification affecting the pattern of expense recognition in the statement of operations. The Company adopted ASU No. 2016-02 on January 1, 2019. The Company recorded a lease asset and lease liability of approximately $0.3 million on its balance sheet as of January 1, 2019, with no material impact on its statement of operations.

The Company has no finance leases and one operating lease for office space in Princeton, NJ. Operating lease expense was $48 and $97 for the three and six months ended June 30, 2019, respectively.

Operating cash flows used for operating leases during the three and six months ended June 30, 2019 were $35 and $75, respectively. As of June 30, 2019, the weighted-average remaining lease term was 1.4 years and the weighted-average discount rate was 21.2%.

Future minimum lease payments under non-cancellable leases as of June 30, 2019 were as follows:


Remainder of 2019	$	100
2020		191
Total	$	291
