Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill	Goodwill Goodwill represents the excess of the purchase price over the estimated fair value of net tangible and identifiable intangible assets acquired in business combinations. We will perform an annual qualitative assessment as of October 1st of each year to determine if it is more likely than not that the fair value is less than the carrying amount. An assessment is performed at other times if an event occurs or circumstances change that would more likely than not reduce the fair value of the asset below its carrying value. As of March 31, 2012, there were no indicators of impairment and no impairment loss was recorded for goodwill during the three months ended March 31, 2012 and 2011.
