Fair Value, Goodwill, Valuation Techniques     Fair values for reporting units are determined based on discounted cash flow models and market multiples. The discounted cash flow model requires inputs to a present value cash flow calculation such as a risk-adjusted discount rate, terminal values, operating budgets, and long-term strategic plans. The fair value from the discounted cash flow model is then combined, based on certain weightings, with market multiples in order to determine the fair value of the reporting unit. These market multiples include revenue multiples and multiples of earnings before interest, taxes, depreciation and amortization.    
Fair Value, Indefinite-lived Intangible Assets (Excluding Goodwill), Valuation Techniques     The fair value of indefinite-lived intangible assets is determined by using a discounted cash flow model. The discounted cash flow model requires inputs to a present value cash flow calculation such as a risk-adjusted discount rate, royalty rates, operating budgets, and long-term strategic plans.
