Note 5. | Leases
The Company has operating and finance leases for facilities and certain equipment. Leases with an initial term of 12 months or less are not recorded on the consolidated balance sheet. Lease expense for operating leases is recognized on a straight-line basis over the lease term. For lease agreements entered into or reassessed after the adoption of Accounting Standards Codification 842, the Company combines lease and non-lease components. See Note 2, Summary of Significant Accounting Policies for additional information. The Company's leases have remaining non-cancelable lease terms of approximately one year to thirteen years, some of which include options to extend the leases for up to ten years, and some of which include options to terminate the lease within one year. The exercise of lease renewal options is at the Company's sole discretion. In certain of the Company’s lease agreements, the rental payments are adjusted periodically to reflect actual charges incurred for common area maintenance, landlord incentives and/or inflation. On November 14, 2018, the Company entered into an office building lease pursuant to which the Company leases one property containing three existing office buildings, comprising approximately 160,000 rentable square feet of space, located in Aliso Viejo, California (Aliso Facility) which was accounted for as a finance lease. The term of the Aliso Facility commenced on April 1, 2019 for expense recognition purposes and continues for thirteen years. The agreement contains an option to extend the lease for two additional five year periods at market rates. Beginning in January 2022, the Company began relocating certain of its corporate administrative headquarters, along with certain laboratory, research and development and warehouse space, to the Aliso Facility. The lease landlord agreed to provide the Company with a tenant improvement allowance in the amount of the cost of any leasehold improvements, not to exceed approximately $12.7 million upon the Company providing the necessary documentation evidencing the costs of the allowable leasehold improvements. All of the aforementioned tenant improvement allowances were utilized by the end of the quarter ended June 30, 2021 and during and as of the year ended December 31, 2021 the Company received $12.7 million in reimbursements. The Company also leases two adjacent facilities located in San Clemente, California and a facility in Burlington, Massachusetts. The total leased square footage of the San Clemente facilities equals approximately 98,000. On July 2, 2020, the Company extended the term of the San Clemente facilities by five years, both of which now expire on May 31, 2030. Each San Clemente facility lease contains an option to extend the lease for one additional five-year period at market rates. The total leased square footage of the Burlington facility is approximately 60,000 square feet, and the lease expires on July 31, 2033. The Burlington facility lease contains an option to extend the lease for one additional five-year period at market rates. ​ The Company currently intends to maintain its manufacturing facilities at its San Clemente and Burlington locations for the foreseeable future. The Company leases approximately 27,000 square feet of office and laboratory space in Waltham, Massachusetts, pursuant to a lease agreement that expires in 2023. ​ The Company’s remaining U.S.-based and foreign subsidiaries’ leased office space totals less than 14,000 square feet.
