The most significant assumptions and estimates relate to the valuation of real estate and related intangible assets and liabilities, equity method investments, other investments, including the assessment of impairments, as well as, depreciable lives, revenue recognition, and the collectability of trade accounts receivable. Application of these assumptions requires the exercise of judgment as to future uncertainties, and, as a result, actual results could differ from these estimates.</p>
