Total marketing related intangible assets with indefinite lives, primarily tradenames, are not subject to amortization, but are subjected to an impairment test at least annually and as triggering events may occur. The impairment test for tradenames consists of a comparison of the fair value of the intangible asset with its carrying amount. An impairment loss is recognized for the amount by which the carrying amount exceeds the fair value of the asset. In making this assessment, we utilized the relief from royalty method, an income approach (a level 3 fair value measurement), which includes assumptions as to future revenue, applicable royalty rate and cost of capital, among others.

In 2010, we determined indicators of impairment were present, primarily due to reduced actual and forecasted revenue, as it relates to our tradenames. Accordingly we performed an impairment test that consisted of a comparison of the fair value of the intangible asset with its carrying amount. We recognized an impairment loss in the amount by which the carrying amount exceeded the fair value of the asset. In making this assessment, we utilized the relief from royalty method, an income approach (level three measurement as defined in FASB ASC Topic 820 that includes assumptions as to future revenue, applicable market-based royalty rate and cost of capital, among others). These impairment charges were $3.3 million and $2.0 million for YRC Freight (the Reimer tradename) and Regional Transportation (the New Penn tradename), respectively.
