The Company tests for goodwill impairment annually or more frequently if indicators of impairment exist or if a decision is made to dispose of a business.  The Company performs its annual goodwill impairment test as of October 1 and monitors for triggering events on an ongoing basis.  The Company determined that as of March 31, 2013, no interim goodwill impairment testing was necessary.  There can be no assurance that the Company’s annual goodwill impairment testing will not result in a charge to earnings.  Any impairment could result in the write-down of the carrying value of goodwill to its implied fair value.
