Leases are classified as either finance leases or operating leases based on criteria in ASC 842. The Company has finance leases for its vehicle and equipment leases and operating leases for its real estate space and office equipment leases. The Company’s operating and finance leases generally have original lease terms between 1 year and 15 years, and in some instances include one or more options to renew. The Company includes options to extend the lease term if the options are reasonably certain of being exercised. The Company currently considers some of its renewal options to be reasonably certain to be exercised. Some leases also include early termination options, which can be exercised under specific conditions. The Company does not have material residual value guarantees or restrictive covenants associated with its leases.

In June 2021, with an effective adoption date of January 1, 2021, the Company adopted ASU 2016-02 using the modified retrospective approach, which permits application of this new guidance at the beginning of the period of adoption, with comparative periods continuing to be reported under ASC 840.

Finance and operating lease assets represent the right to use an underlying asset for the lease term, and finance and operating lease liabilities represent the obligation to make lease payments arising from the lease.

The Company calculates the present value of its finance and operating leases using an estimated incremental borrowing rate (“IBR”), which requires judgment. For real estate operating leases, the Company estimates the IBR based on prevailing market rates for collateralized debt in a similar economic environment with similar payment terms and maturity dates commensurate with the terms of the lease. For all other leases, the Company estimates the IBR based on the stated interest rate on the contract. Since many of the inputs used to calculate the rate implicit in the leases are not readily determinable from the lessee’s perspective, the Company will not use the implicit interest rate.

Certain leases contain variable payments, these payments are expensed as incurred and not included in the Company’s operating lease right-of-use assets and operating lease liabilities. These amounts primarily include payments for maintenance, utilities, taxes, and insurance and are excluded from the present value of the Company’s lease obligations.

As of the adoption date, the Company recognized operating lease right-of-use assets, current operating lease liabilities and operating lease liabilities, net of current portion of $24.6 million, $7.3 million and $17.3 million, respectively. As of the adoption date, the Company recognized finance lease right-of-use assets, current finance lease liabilities and finance lease liabilities, net of current portion of $7.2 million, $2.9 million and $4.6 million, respectively.

As part of this adoption, the Company elected to not record operating lease right-of-use assets or operating lease liabilities for leases with an initial term of 12 months or less. The Company also elected to combine lease and non-lease components on all new or modified operating leases into a single lease component for all classes of assets.

Total rent expense under operating leases was $2.2 million and $6.4 million for the three and nine months ended September 30, 2020, respectively.
