Non-GAAP Financial Measures

This press release includes FFO and NOI, including same property NOI growth, which are financial performance measures not defined by generally accepted accounting principles in the United States (“GAAP”). Reconciliations of these non-GAAP financial measures to the most directly comparable GAAP measures are included in this press release. FFO and same property NOI growth are financial performance measures widely used by securities analysts, investors and other interested parties in the evaluation of REITs. These measures should not be considered as alternatives to net income (determined in accordance with GAAP) as an indicator of financial performance and are not alternatives to cash flow from operating activities

2

(determined in accordance with GAAP) as a measure of liquidity. Non-GAAP financial 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 to financial results presented in accordance with GAAP. Computation of these non-GAAP measures may differ in certain respects from the methodology utilized by other REITs and, therefore, may not be comparable to such other REITs. Investors are cautioned that items excluded from FFO are significant components in understanding and addressing financial performance.

For a reconciliation of these measures and other information, please refer to the attached tables.
