Leases [Abstract]
Weighted average discount rate for operating leases	8.00%	[1]	8.00%

[1] The Company used 8.0%, its estimated incremental borrowing rate for similar secured assets, as the discount rate for the leases to determine the present value of the lease payments because the implicit rate in each lease is not readily determinable. The discount rate was calculated on the basis of information available as of January 1, 2019, the application date.
