Actual results could differ from these estimates. DHI’s significant estimates include the useful lives and valuation of fixed assets and intangible assets, goodwill, the income tax valuation allowance, and the assumptions used to value the Performance-Based Restricted Stock Units (“PSUs”) of the Company.</font></div></div>
