Schedule of finite-lived intangible assets

Amortization is recognized in earnings on a straight-line basis over the estimated useful lives of intangible assets from the date that they are available for use. The amortization periods of finite-lived intangible assets are re-evaluated periodically when facts and circumstances indicate that the remaining useful lives may have changed. Indefinite-lived trade names and trademarks are not amortized. The estimated useful lives of the Company's intangible assets are as follows:


Asset						Rate / term
Trade names and trademarks						2 - 15 years or indefinite-lived
Customer relationships						6 - 20 years
Software and technology assets						3 - 7 years
