5. Contract Acquisition Costs and Intangible Asset

Contract acquisition costs and intangible asset are summarized as follows:

​

​

We amortize the value of the contract acquisition costs and intangible asset on a pro-rata basis based on the estimated total service revenue or net profits to be recognized over the period from November 18, 2020 through December 2032, the termination date of the Promotion Agreement (see Note 2 Basis of Presentation, Significant Accounting Policies and Fair Value Measurements). Amortization of contract acquisition costs is recorded as a reduction of service revenue, net, and amortization of the intangible asset is recorded as cost of service revenue.

We recorded amortization related to the contract acquisition costs of $0.1 million for both the three months ended March 31, 2026 and 2025. We recorded amortization related to the intangible asset of $0.1 million and less than $0.1 million for the three months ended March 31, 2026 and 2025, respectively. Annual amortization over the next five years is expected to immaterially fluctuate from the 2026 amounts, consistent with changes to net profits to be recognized pursuant to the Promotion Agreement over the period.
