Customer contract incentives consist principally of incentives provided to new or existing customers to convert their customer accounts to, or retain their customer accounts on, our solutions. Customer contract incentives are amortized ratably over the contract period to include renewal periods, if applicable, which as of December 31, 2022, have termination dates that range from 2024 to 2026. The amortization of customer contract incentives is reflected as a reduction of revenue in our Income Statements.

(5)

Capitalized costs are related to: (i) customer conversion/set-up activities; and (ii) direct material costs to fulfill long-term revenue management solutions and managed services arrangements. These costs are amortized over the contract period based on the transfer of goods or services to which the assets relate, which as of December 31, 2022, range from 2023 to 2036, and are included in cost of revenue in our Income Statements.

(6)

Capitalized commission fees are incremental commissions paid as a result of obtaining a customer contract. These fees are amortized over the contract period based on the transfer of goods or services to which the assets relate, which as of December 31, 2022, range from 2023 to 2028, and are included in selling, general and administrative (“SG&A”) expenses in our Income Statements. Incremental commission fees incurred as a result of obtaining a customer contract are expensed when incurred if the amortization period of the asset that we otherwise would have recognized is one year or less.
