The significant estimates made by management relate to the allowance for doubtful accounts, the costs and revenue relating to the Company’s construction contracts, stock-based compensation assumptions, valuation allowance related to deferred tax assets, fair value of long-lived assets, the useful lives of towers and intangible assets, anticipated property tax assessments, fair value of investments and asset retirement obligations. Management develops estimates based on historical experience and on various assumptions about the future that are believed to be reasonable based on the information available. These estimates ultimately may differ from actual results and such differences could be material. </span></p>
