The Company’s significant estimates include reserves for self-insured retention related to general liability insurance, workers’ compensation insurance, auto liability insurance, medical malpractice insurance, employer group health insurance, projected undiscounted cash flows used to evaluate asset impairment, estimated fair </span></div><div style="line-height:120%;padding-top:6px;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">values of business acquisitions, pension assumptions, percentage of completion and estimated cost to complete for construction projects, recoverability of notes receivable, estimated useful lives of property and equipment and intangible assets, stock based compensation and allowance for doubtful accounts. These estimates and assumptions affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. While the Company believes that such estimates are reasonable when considered in conjunction with the consolidated financial statements taken as a whole, the actual amounts of such estimates, when known, will vary from these estimates. If actual results significantly differ from the Company’s estimates, the Company’s financial condition and results of operations could be materially impacted.</span></div>

Other than cash, financial instruments that potentially subject the Company to concentrations of credit risk consist principally of trade accounts receivable, contract receivable, long-term debt and financial instruments used in hedging activities. The Company’s cash management and investment policies restrict investments to low-risk, highly liquid securities, and the Company performs periodic evaluations of the credit standing of the financial institutions with which it deals.</span></div>
