Our estimates include, but are not limited to, valuation of deferred income taxes, stock-based compensation, net realizable value of inventory, capitalization of website and software development costs, the incremental borrowing rate for the determination of the present value of lease payments, recoverability of intangible assets with finite lives, fair value of our mortgage loans held for sale, fair value of interest rate lock commitments ("IRLCs") and forward sales commitments, fair value of reporting units for purposes of evaluating goodwill for impairment, current expected credit losses on certain financial assets, and the fair value of the convertible feature related to our convertible senior notes. The amounts ultimately realized from the affected assets or ultimately recognized as liabilities will depend on, among other factors, general business conditions and could differ materially in the near term from the carrying amounts reflected in the consolidated financial statements.</span>
