The Company is exposed to concentrations of credit risk relating to its receivables due from customers in the industries described above. The Company does not generally require collateral or other security to support its outstanding receivables. The Company minimizes its credit risk relating to receivables by performing ongoing credit evaluations. The Company is also exposed to concentrations of credit risk associated with cash and cash equivalents. The Company minimizes its credit risk relating to these positions by monitoring the financial condition of the financial institutions and counterparties involved and by primarily conducting business with large, well-established financial institutions and diversifying its counterparties. </font></div></div>

The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Such estimates include, among other items, those related to allowance for doubtful accounts, useful lives of property and equipment, inventories, income tax provisions, impairments, fair values used in purchase price allocations and certain accrued and contingent liabilities. Actual results could differ from those estimates and those differences may be material.</font></div></div>
