The Company recognizes right-of-use (“ROU”) assets and lease liabilities when it obtains the right to control an asset under a leasing arrangement with an initial term greater than twelve months. The Company leases its facilities under non-cancellable operating and financing leases.

The Company evaluates the nature of each lease at the inception of an arrangement to determine whether it is an operating or financing lease and recognizes the ROU asset and lease liabilities based on the present value of future minimum lease payments over the expected lease term. The Company’s leases do not generally contain an implicit interest rate and therefore the Company uses the incremental borrowing rate it would expect to pay to borrow on a similar collateralized basis over a similar term in order to determine the present value of its lease payments.

Pursuant to a 2014 sublease agreement (the “2014 Sublease”) and a 2015 sublease agreement (the “2015 Sublease”) the Company subleased portions of its leased premises in Galway, Ireland to a sublessee. On May 15, 2020, the Company and its sublessee entered into amendments to the 2014 Sublease and the 2015 Sublease pursuant to which (i) the 2014 Sublease and 2015 Sublease were extended from May 31, 2020 to August 2, 2021, (ii) effective July 1, 2020, the leased premises under the 2015 Sublease would be expanded to include an additional 4,999 square feet of space, and (iii) effective July 1, 2020, the rent under the 2015 Sublease would increase from approximately $14.6 per month to $20.6 per month. The Company analyzed the terms of the amended 2014 Sublease and 2015 Sublease and determined that its ROU asset for the master operating lease was not impaired as a result of the amendments. On June 25, 2020, the Company entered into a sub-lease agreement (the “2021 Sub-Lease”) with its previous sublessee under the 2014 Sublease and 2015 Sublease pursuant to which, effective August 2, 2021, the previous sublessee would become the lessee and the Company would then sub-lease its portion of the premises in Galway, Ireland from the previous sublessee. The Company rent under the 2021 Sub-Lease is approximately $3.7 per month for a term of five years.
