LEASES | ​ 13. LEASES ​ CubeSmart as Lessor ​ The Company derives rental revenue primarily from rents received from customers who rent units at its self-storage properties under month-to-month leases for personal or business use. The self-storage lease agreements utilized by the Company vary slightly to comply with state-specific laws and regulations, but, subject to such laws and regulations, generally provide for automatic monthly renewals, flexibility to increase rental rates over time as market conditions permit and the collection of contingent fees such as administrative and late fees. None of the self-storage lease agreements contain options that allow the customer to purchase the leased self-storage space at any time during, or at the expiration of, the lease term. All self-storage leases in which the Company serves as lessor have been classified as operating leases. Accordingly, storage units are carried at historical cost less accumulated depreciation and impairment, if any, and are included in Storage properties on the Company’s consolidated balance sheets. Operating lease income for amounts received under the Company’s self-storage lease agreements is recognized on a straight-line basis which, due to the month-to-month nature of the leases, results in the recognition of income during the initial term and each subsequent monthly renewal using the then-in-place rent amount. Operating lease income is included in Rental income within the Company’s consolidated statements of operations. Variable lease income related to the Company’s self-storage lease agreements consists of administrative and late fees charged to customers. For the years ended December 31, 2025, 2024 and 2023, administrative and late fees totaled $37.2 million, $34.3 million, and $30.0 million, respectively, and are included in Other property related income within the Company’s consolidated statements of operations. CubeSmart as Lessee ​ The Company serves as lessee in lease agreements for land, office space, automobiles and certain equipment, which have remaining lease terms of up to 39 years. Certain of the Company’s leases (1) provide for one or more options to renew, with renewal options that can extend the lease up to 69 years, (2) allow for early termination at certain points during the lease term and/or (3) give the Company the option to purchase the leased property. In all cases, the exercise of the lease renewal, termination and purchase options, if provided for in the lease, are at the Company’s sole discretion. Certain of the Company’s lease agreements, particularly its land leases, require rental payments that are periodically adjusted for inflation using a defined index. None of the Company’s lease agreements contain any material residual value guarantees or material restrictive covenants. Lease expense for payments related to the Company’s finance leases is recognized as interest expense using the interest method over the related lease term. Lease expense for payments related to the Company’s operating leases is recognized on a straight-line basis over the related lease term, which includes options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. ​ Right-of-use assets represent the Company’s right to use an underlying asset during the lease term and lease liabilities represent the Company’s obligation to make lease payments as specified in the lease. Right-of-use assets and lease liabilities related to the Company’s operating leases are recognized at the lease commencement date based on the present value of the remaining lease payments over the lease term. As the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available regarding the Company’s unsecured borrowing rates and implied secured spread at the lease commencement date in determining the present value of lease payments. The right-of-use asset also includes any lease payments made at or before lease commencement less any lease incentives. ​ For the years ended December 31, 2025, 2024 and 2023, the Company’s lease cost consists of the following components: ​
