As discussed in Note 2 to the consolidated financial statements, we review the carrying value of goodwill for impairment annually at June 30 and whenever events or circumstances indicate the carrying value may not be recoverable. The estimates and assumptions about future results of operations and cash flows made in connection with the impairment testing could differ from future actual results of operations and cash flows. While we have concluded, for each year presented in the financial statements included in this report, that our goodwill is not impaired, future events could cause us to conclude that the intangible asset values associated with a given operation may become impaired. Any resulting non-cash impairment charge could have a material adverse effect on our business, results of operations and financial position.
