These forward-looking statements involve known and unknown risks and uncertainties, which may cause Public Storage’s actual results and performance to be materially different from those expressed or implied in the forward-looking statements. Factors and risks that may impact future results and performance are described from time to time in Public Storage’s filings with the Securities and Exchange Commission, including in Item 1A, “Risk Factors” in Public Storage’s Annual Report on Form 10-K for the fiscal year ended December 31, 2020.

Public Storage disclaims any obligation to update publicly or otherwise revise any forward-looking statements, whether as a result of new information, new estimates, or other factors, events or circumstances after the date of this presentation, except where required by law. Non-GAAP Measures This document contains non-GAAP measures, including EBITDA. Non-GAAP measures should not be considered as an alternative to, or more meaningful than, net income (determined in accordance with GAAP) or other GAAP financial measures, as an indicator of financial performance and is not an alternative to, or more meaningful than, cash flow from operating activities (determined in accordance with GAAP) as a measure of liquidity. Non-GAAP measures have limitations as they do not include all items of income and expense that affect operations and, accordingly, should always be considered as supplemental financial results to those presented in accordance with GAAP. In addition, other REITs may compute these measures differently, so comparisons among REITs may not be helpful. Computation of NOI Net operating income or “NOI” is a non-GAAP financial measure that excludes the impact of depreciation and amortization expense, which is based upon historical real estate costs and assumes that building values diminish ratably over time, while we believe that real estate values fluctuate due to market conditions. See our Form 10-K filed with the SEC and our other Exchange Act periodic reports filed with the SEC for reconciliation of NOI to our net income as computed in accordance with GAAP.
