Leases
Finance Lease
In May 2020 and January 2021, we entered into an agreement and the first amendment with Hovione, our third-party manufacturer, to increase our manufacturing of Captisol, respectively. The agreements are considered to include an embedded finance lease under ASC 842, Leases, as it provides the Company the right to use the underlying equipment to exclusively manufacture Captisol. As of December 31, 2021, we had fully paid consideration of $69.1 million for prepaid inventory and capacity ramp-up fee. We assigned consideration in the agreements between lease and non-lease components using relative standalone prices. Since the inception of the agreements, we have assigned $50.2 million of the consideration paid to the non-lease component which is accounted for as prepaid inventory and being amortized to cost of Captisol based on the usage. The remaining balance of $18.9 million was recognized as a right of use asset.
We recorded a $9.8 million of impairment charge based on the fair value of the right of use asset which has been recognized in cost of Captisol in our consolidated statement of operations for the year ended December 31, 2022. As of December 31, 2022, the remaining right of use asset balance was $4.0 million which will be amortized straight-line over the remaining 6 years lease term. During the years ended December 31, 2025, 2024 and 2023, no impairment to this asset group was recorded as there were no indicators of impairment. As of December 31, 2025 and 2024, the remaining right of use asset balance is $2.0 million and $2.7 million, respectively.
Operating Lease
We lease certain administration office facilities, research and development facilities and equipment primarily under various operating leases. Our operating leases have remaining contractual terms up to seven years, some of which include options to extend the leases for up to five years. Lease assets and lease liabilities are recognized at the commencement of an arrangement where it is determined at inception that a lease exists. Lease assets represent the right to use an underlying asset for the lease term, and lease liabilities represent the obligation to make lease payments arising from the lease. These assets and liabilities are initially recognized based on the present value of lease payments over the lease term, including upfront lease payments made and lease incentives, calculated using our incremental borrowing rate generally applicable to the location of the lease asset, unless the implicit rate is readily determinable. Lease terms include options to extend or terminate the lease when it is reasonably certain that those options will be exercised.
In addition to base rent, certain of our operating leases require variable payments, such as insurance and common area maintenance. These variable lease costs, other than those dependent upon an index or rate, are expensed when the obligation for those payments is incurred. Leases with an initial term of twelve months or less are not recorded on the consolidated balance sheets, and the expense for these short-term leases and for operating leases is recognized on a straight-line basis over the lease term.The depreciable life of lease assets and leasehold improvements is limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise.
