Actual results could differ from those estimates. Significant estimates, including the underlying assumptions, consist of the economic lives of long lived assets, realizability of trade receivables, valuation of deferred tax assets/liabilities, inventory, investments, contingent earn-out, and stock compensation expense. It is at least reasonably possible that these estimates may change in the near term.</font></p> </div>
