The Company leases office space under operating leases. The lease liability is initially measured at the present value of the lease payments to be made over the lease term. Lease payments are comprised of the fixed and variable payments to be made by the Company to the lessor during the lease term minus any incentives or rebates or abatements receivable by the Company from the lessor or the owner. Payments for non-lease components do not form part of lease payments. The lease term includes renewal options only if these options are specified in the lease agreement and if failure to exercise the renewal option imposes a significant economic penalty for the Company. As there are no significant economic penalties, renewal cannot be reasonably assured and the lease terms for the office space do not include any renewal options. The Company has not entered into any leases with related parties. The Company accounts for short-term leases (i.e., lease term of 12 months or less) by making the short-term lease policy election and will not apply the recognition and measurement requirements of ASC 842.

The Company has determined that the rate implicit in the lease is not determinable and the Company does not have borrowings with similar terms and collateral. Therefore, the Company considered a variety of factors, including the Company’s credit rating, observable debt yields from comparable companies with a similar credit profile and the volatility in the debt market for securities with similar terms, in determining that 11.5% was reasonable to use as the incremental borrowing rate for purposes of the calculation of lease liabilities and a change of 1% would not result in a material change to the Company’s condensed consolidated financial statements.

On September 30, 2011, the Company entered into an agreement for office space in Dublin, Ireland which terminates on October 31, 2019 and can be extended automatically for successive on year periods. On July 1, 2011, the Company leased office space in Bedminster, New Jersey. The lease, as amended, terminates on September 15, 2019, to coincide with the start of the new Bridgewater, New Jersey lease, as described below. On January 26, 2019, the Company leased additional space in another building in Bedminster, New Jersey, effective February 1, 2019 and terminating June 30, 2019.

These leases have been determined to be short-term leases and the Company is committed to making aggregate payments of approximately $0.3 million during the next twelve months.

On February 5, 2019, the Company entered into a lease agreement for new office space in Bridgewater, New Jersey (the “Lease”). The Lease will commence upon delivery of the premises after certain improvements are made, which is anticipated to be on or about August 15, 2019 (the “Commencement Date”) for an 11-year period, with two five-year renewal options. Subject to the terms of the Lease, Amarin will have a one-time option to terminate the agreement effective on the first day of the ninety-seventh month after the Commencement Date upon advance written notice and a termination payment specified in the Lease. Under the Lease, the Company will pay monthly rent of approximately $0.1 million for the first year following the Commencement Date, and such rent will increase by a nominal percentage every year following the first anniversary of the Commencement Date. In addition, Amarin will receive certain abatements subject to the limitations in the Lease. The operating lease liability is $9.0 million, of which the current operating lease liability of $1.1 million is recorded in accrued expenses and other current liabilities on the condensed consolidated balance sheet, and the operating lease right-of-use asset is $8.9 million, as of March 31, 2019. The lease expense for the three months ended March 31, 2019 is approximately $0.3 million.
