Leases |
Leases | 6. Leases The Company has operating leases for off-campus classroom and laboratory site locations, office space, office equipment, and optical fiber communication lines. These leases have terms that range from one month to ten years and four months. At lease inception, we determine the lease term by assuming no exercises of renewal options, due to the Company’s constantly changing geographical needs for its university partners. Leases with an initial term of 12 months or less are not recorded in the consolidated balance sheets and we recognize lease expense for these leases on a straight-line basis over the lease term. The Company has operating lease costs of $16,694, $13,496 and $10,666 for the years ended December 31, 2024, 2023 and 2022, respectively. As of December 31, 2024, the Company had $17,029 of non-cancelable operating lease commitments for four off-campus classroom and laboratory sites that had not yet commenced. The Company’s weighted-average remaining lease term relating to its operating leases is 7.62 years, with a weighted-average discount rate of 4.22%. The cash paid for operating lease liabilities was $14,895, $11,391 and $9,537 for the years ended December 31, 2024, 2023 and 2022, respectively.
