| Contract Cost Assets |
TDS Telecom expects that commission fees paid as a result of obtaining contracts are recoverable, and therefore TDS defers and amortizes these costs. As a practical expedient, costs with an amortization period of one year or less are expensed as incurred. TDS also incurs fulfillment costs, such as installation costs, where there is an expectation that a future benefit will be realized. Deferred commission fees and fulfillment costs are amortized based on the timing of transfer of the goods or services to which the assets relate, typically the contract term. Contract cost asset balances, which are recorded in Other assets and deferred charges in the Consolidated Balance Sheet, were as follows: | | | | | | | | | | | | | June 30, 2026 | | December 31, 2025 | | (Dollars in thousands) | | | | | Costs to obtain contracts | | | | | Sales commissions | $ | 18,498 | | | $ | 14,770 | | | Fulfillment costs | | | | | Installation costs | 1,769 | | | 1,872 | | | | | | | Total contract cost assets | $ | 20,267 | | | $ | 16,642 | |
