Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets, Policy	Goodwill represents the excess of acquisition costs over the fair value of the net tangible assets and identifiable intangible assets acquired in a business combination. Other indefinite-lived intangible assets primarily consist of trademarks acquired in business combinations. Goodwill and other indefinite-lived assets are not amortized, but are subject to impairment testing. The aggregate carrying values of our goodwill and other indefinite-lived intangible assets are subject to an impairment assessment annually as of October 1, or whenever events or changes in circumstances indicate that the carrying amount may not be fully recoverable. This assessment compares carrying values of the goodwill reporting units and other indefinite lived intangible assets to their respective fair values and, when appropriate, the carrying value is reduced to fair value. In testing goodwill, the fair value of each reporting unit is estimated using the income approach, a discounted cash flow approach. For the other indefinite lived intangible assets, fair value is estimated using the relief from royalty method. Management utilizes long-term cash flow forecasts and the Company's annual operating plans adjusted for terminal value assumptions. The fair value of the Company's reporting units and other indefinite lived intangible assets are determined utilizing the best estimate of future revenues, operating expenses including commission expense, market and general economic conditions, trends in the industry, as well as assumptions that management believes marketplace participants would utilize including discount rates, cost of capital, trademark royalty rates, and long-term growth rates. The trademark royalty rate was determined by reviewing similar trademark agreements with third parties. Although management believes that assumptions are reasonable, actual results may vary significantly.
