Goodwill Impairment	9 Months Ended

Asset Impairment Charges [Abstract]
Asset Impairment Charges [Text Block]	Note 2 – Goodwill Impairment As discussed in Note 1 to the Consolidated Financial Statements in our 2011 Annual Report on Form 10-K, goodwill represents the excess of the amount we paid to acquire a company over the estimated fair value of tangible assets and identifiable intangible assets acquired, less liabilities assumed. We test goodwill and other indefinite lived intangible assets for impairment annually as of October 1st and at any other time when impairment indicators exist. For our annual goodwill impairment test, we estimate the fair value of our reporting units by utilizing a present value model that incorporates our assumptions for projected future cash flows, discount rates and multiples. These assumptions are considered unobservable inputs (Level 3 inputs as defined in the accounting guidance). If the estimated fair value of any of our reporting units has fallen below their carrying value, we compare the estimated fair value of the reporting unit's goodwill to its carrying value. If the carrying value of a reporting unit's goodwill exceeds its estimated fair value, we recognize the difference as an impairment loss in operating income. Since we define an operating segment as an individual sales center and we do not have operations below the sales center level, our reporting unit is an individual sales center. We performed an interim goodwill impairment analysis for our United Kingdom reporting unit during the third quarter of 2012 based on our identification of impairment indicators related to our results through the end of the 2012 pool season and the current and expected continued depressed economic conditions in the United Kingdom. Our results for the nine months ended September 30, 2012 were significantly lower than our 2012 sales, gross profit and operating profit estimates for the United Kingdom reporting unit that we used in our 2011 annual goodwill impairment test. We updated our 2011 impairment analysis for both our actual 2012 year to date results and our updated growth estimates for future years based on expectations for a more prolonged economic recovery period in the United Kingdom. These updates had a significant impact on our projected future cash flow calculation and resulted in a much lower estimated fair value for our United Kingdom reporting unit. As a result of our interim impairment analysis, we recorded a $6.9 million non-cash goodwill impairment charge equal to the total September 30, 2012 goodwill carrying amount of our United Kingdom reporting unit of $6.9 million. Since the goodwill impairment charge is non‑deductible for tax purposes, our effective tax rate for both the quarterly and year to date periods ended September 30, 2012 was much higher than normal.
