For equipment leases with immaterial non-lease components incorporated into the fixed rent payment, the Company accounts for the lease and non-lease components as a single lease component in determining the lease payment. The adoption of ASC 842 on July 1, 2019 resulted in the Company recording $1,423 of operating lease liabilities and an equal amount of ROU assets with no impact on retained earnings. The adoption did not have a material impact on the Company’s condensed consolidated statement of operations or condensed consolidated statement of cash flows for the three and nine months ended March 31, 2020.

Adoption of Recently Issued Accounting Standards

ASC 842, “Leases” – On July 1, 2019, the Company adopted cumulative accounting standard updates initially issued by the Financial Accounting Standards Board (“FASB”) that amend the accounting for leases and are codified as Accounting Standards Codification (“ASC”) 842. These lease accounting changes require operating leases be recorded on the balance sheet through the recognition of a liability for the discounted present value of future fixed lease payments and a corresponding right-of-use (“ROU”) asset. The Company’s accounting for finance leases remained substantially unchanged from its prior accounting for capital leases. The ROU asset recorded at commencement of the lease represents the right to use the underlying asset over the lease term in exchange for the lease payments. Leases with an initial term of 12 months or less which do not have an option to purchase the underlying asset that is deemed reasonably certain to be exercised are not recorded on the balance sheet; rather, rent expense for these leases is recognized on a straight-line basis over the lease term, or when incurred if a month-to-month lease. When readily determinable, the Company uses the interest rate implicit in a lease to determine the present value of future lease payments. For leases where the implicit rate is not readily determinable, the Company’s incremental borrowing rate is utilized. Our lease agreements do not contain any material residual value guarantees.

The Company elected the amended transition requirements allowed for by the FASB in Accounting Standards Update (“ASU”) 2018-11, which provides relief from requirements to recast prior comparative periods under ASC 842. As a result, the prior year comparative financial statements have not been restated to reflect the adoption of ASC 842. Additionally, the Company elected the “package of practical expedients” available in ASC 842 whereby an entity need not reassess expired contracts for lease identification or classification as a finance or operating lease, or reassess the initial direct costs. The Company has not elected the practical expedient to use hindsight to determine the lease term for its leases at transition. Certain of the Company’s lease agreements have lease and non-lease components, which for the majority of leases the Company accounts for separately when the actual lease and non-lease components are determinable. For equipment leases with immaterial non-lease components incorporated into the fixed rent payment, the Company accounts for the lease and non-lease components as a single lease component in determining the lease payment.

The adoption of ASC 842 on July 1, 2019 resulted in the Company recording $1,423 of operating lease liabilities and an equal amount of ROU assets with no impact on retained earnings. The adoption did not have a material impact on the Company’s condensed consolidated statement of operations or condensed consolidated statement of cash flows for the three and nine months ended March 31, 2020.
