The Company has two operating leases for office and manufacturing space which requires it to pay base rent and certain utilities. Monthly rent expense is recognized on a straight-line basis over the terms of the leases, which expire in 2027 and 2021.
At June 30, 2021, the weighted average remaining lease term was 6.5 years. The operating leases are included in the balance sheets at the present value of the lease payments at a 7% discount rate, which approximates using the rate of interest that the Company would have to pay to borrow on a collateralized basis over a similar term and amount equal to the lease payments in a similar economic environment as the leases do not provide an implicit rate.
For each of the three months ended June 30, 2021 and 2020, operating lease expense and cash paid for leases were $0.1 million. For each of the six months ended June 30, 2021 and 2020, operating lease expense and cash paid was $0.3 million. Operating lease right-of-use assets amortization was $0.1 million and $0.2 million for each the three and six months ended June 30, 2021 and 2020, respectively. Variable costs are de minimis.
