Transaction price allocated to the remaining performance obligations

The following table includes estimated service revenue expected to be recognized related to performance obligations that are unsatisfied (or partially unsatisfied) at the end of the reporting period. These estimates represent service revenue to be recognized when wireless services are delivered to customers pursuant to service plan contracts and under certain roaming agreements with other carriers. These estimates are based on contracts in place as of June 30, 2019, and may vary from actual results due to future contract modifications. As a practical expedient, revenue related to contracts of less than one year, generally month-to-month contracts, are excluded from these estimates.



	Service Revenue
(Dollars in millions)
Remainder of 2019	$	169
2020	104
Thereafter	229
Total	$	502

U.S. Cellular has certain contracts in which it bills an amount equal to a fixed per-unit price multiplied by a variable quantity (e.g., certain roaming agreements with other carriers). Because U.S. Cellular invoices for such items in an amount that corresponds directly with the value of the performance completed to date, U.S. Cellular may recognize revenue in that amount. As a practical expedient, these contracts are excluded from the estimate of future revenues expected to be recognized related to performance obligations that are unsatisfied as of the end of a reporting period.

Contract Cost Assets

U.S. Cellular expects that incremental commission fees paid as a result of obtaining contracts are recoverable and therefore U.S. Cellular capitalizes these costs. As a practical expedient, costs with an amortization period of one year or less are not capitalized. The contract cost asset balance related to commission fees was $131 million at June 30, 2019, and $139 million at December 31, 2018, and was recorded in Other assets and deferred charges in the Consolidated Balance Sheet. Capitalized commission fees are amortized based on the timing of transfer of the goods or services to which the assets relate, typically the contract term which ranges from fifteen months to thirty months. Amortization of contract cost assets was $27 million and $55 million for the three and six months ended June 30, 2019, respectively, and $26 million and $54 million for the three and six months ended June 30, 2018, respectively, and was included in Selling, general and administrative expense.
