Cost Method Investments [Abstract]
Cost Method Investments [Text Block]	Cost Method Investments At December 31, 2011 and 2010, the carrying value of our cost method investments was $23.6 million and $24.8 million, respectively and are included in other assets in our balance sheet.

The entire disclosure for investments accounted for under the cost-method. The carrying amount of such investments may be adjusted, for example, distributions in excess of cost (return of capital) or for other-than-temporary impairments. The cost method and lower-of-cost or market, an adaptation of the cost method, is generally followed for most investments in noncontrolled corporations, in some corporate joint ventures, and to a lesser extent in unconsolidated subsidiaries in which the entity does not have the ability to exercise significant influence.
