We have evaluated the carrying values of our goodwill and other indefinite-lived intangible assets as of November 1, 2013. We determine any impairment of goodwill by comparing the carrying amounts of our reporting units with fair values, which we estimate using a combination of a market multiple and discounted cash flow approach. In completing this evaluation, we determined that no reporting unit has a fair value below its net carrying value and therefore, no impairment was required.

Other intangible assets consist of the following:
