These policies may require management to make estimates, judgments and assumptions that we believe are reasonable based on our historical experience, contract terms, observance of known trends in our Company and the industry as a whole and information available from other outside sources. Our estimates affect the reported amounts of assets and liabilities and related disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expense during the reporting period. Actual results may differ from those initial estimates. Our most critical estimates relate to revenue recognition, goodwill and other intangible assets, and property and equipment.</font></div></div>
