Variable Interest Entity [Line Items]    
Percentage of ownership interest in GED 50.00%  
Growth rate percent share in GED's 5.00%  
Terms of agreement Under the terms of the joint venture agreement, as restructured in 2007, we received the greater of 50% of GED's member distribution as prescribed under the joint venture agreement, or a 5% growth rate in its 50% share of GED's prior year member distribution through the expiration of the GED management contract on August 31, 2011. GED was a variable interest entity due to the fact that we had limited exposure to risk of loss. Therefore, we did not consolidate, but accounted for its investment using the equity method.
