We record a receivable related to revenue recognized when we have an unconditional right to invoice. There were no material contract assets as of June 30, 2019 or December 31, 2018. Trade receivables were $1.07 billion and $1.09 billion at June 30, 2019 and December 31, 2018, respectively. Impairment losses on receivables were not material during the second quarters of 2019 and 2018.

Contract liabilities primarily relate to payments received in advance of performance under the contract. Changes in contract liabilities are due to our performance under the contract. The amount of deferred revenue as of January 1, 2019 recognized during the three and six months ended June 30, 2019 was $43 million and $101 million, respectively. In addition, we deferred

consideration of $45 million and $102 million received in advance of performance during the three and six months ended June 30, 2019, respectively, resulting in an increase in deferred revenue. Refer to Note 5, "Accrued Expenses and Other Liabilities," for additional information on deferred revenue.

Revenue allocated to remaining performance obligations represents contracted revenue that has not yet been recognized (“contracted not recognized revenue”). Contracted not recognized revenue includes deferred revenue and amounts for full service ChoiceLease maintenance revenue that will be recognized as revenue in future periods as we provide maintenance services to our customers. Contracted not recognized revenue excludes variable consideration as it is not included in the transaction price consideration allocated at contract inception. Contracted not recognized revenue was $2.8 billion as of June 30, 2019.

We capitalize incremental sales commissions paid as a result of obtaining ChoiceLease, DTS and SCS service contracts as contract costs. Capitalized sales commissions totaled $106 million and $107 million at June 30, 2019 and December 31, 2018, respectively. Capitalized sales commissions include initial direct costs of our leases of $53 million at both June 30, 2019 and December 31, 2018. Capitalized sales commissions are presented in “Sales-type leases and other assets” in our Consolidated Condensed Balance Sheets.

Capitalized sales commissions related to our ChoiceLease product are amortized based on the same pattern that the revenue is recognized for the underlying lease or non-lease components of the contract; generally on a straight-line basis for the lease component and consistent with the estimated pattern of maintenance costs for the non-lease component. We allocate the ChoiceLease commissions to the lease and non-lease components based on the same allocation of the contract consideration. The amortization period aligns with the term of our contract, which typically ranges from three to seven years, and amortization expense is included in “Selling, general and administrative expenses” in our Consolidated Condensed Statements of Earnings.

Capitalized sales commissions related to our DTS and SCS service contracts are amortized based on the same pattern that the revenue is recognized for the underlying contracts. This generally results in a straight-line amortization as the amount of revenue billed to the customer under DTS and SCS contracts corresponds directly with the value to the customer of our performance completed to date. The amortization period aligns with the expected term of the contract, which typically ranges from three to five years, and amortization expense is included in “Selling, general and administrative expenses” in our Consolidated Condensed Statement of Earnings.
