Because FFO excludes significant economic components of net income including depreciation and amortization, FFO should be used as an adjunct to net income and not as an alternative to net income. The principal limitation of FFO is that it does not represent cash flow from operations as defined by GAAP and is a supplemental measure of performance that does not replace net income as a measure of performance or net cash provided by operating activities as a measure of liquidity. In addition, FFO is not intended as a measure of a REIT’s ability to meet debt principal repayments and other cash requirements, nor as a measure of working capital. FFO only provides investors with an additional performance measure. Other REITs may use different methods for calculating FFO and, accordingly, the Company’s FFO may not be comparable to other REITs.

⁽²⁾ Investors in and analysts following the real estate industry utilize net operating income (“NOI”) as a supplemental performance measure. NOI is derived from revenues (determined in accordance with GAAP) minus property operating expenses and real estate taxes (determined in accordance with GAAP). NOI does not represent cash generated from operating activities in accordance with GAAP and should not be considered to be an alternative to net income (determined in accordance with GAAP) as an indication of the Company’s financial performance or to be an alternative to cash flow from operating activities (determined in accordance with GAAP) as a measure of the Company’s liquidity; nor is it indicative of funds available for the Company’s cash needs, including its ability to make cash distributions. The Company believes that net income is the most directly comparable GAAP measurement to net operating income. Net income includes interest and depreciation and amortization which often have no effect on the market value of a property and therefore limit its use as a performance measure. In addition, such expenses are often incurred at a parent company level and therefore are not necessarily linked to the performance of a real estate asset. The Company believes that net operating income is helpful to investors as a measure of operating performance because it is an indicator of the return on property investment, and provides a method of comparing property performance over time. The Company uses NOI as a key management tool when evaluating performance and growth of particular properties and/or groups of properties. The principal limitation of NOI is that it excludes depreciation, amortization and non-property specific expenses such as general and administrative expenses, all of which are significant costs, and therefore, NOI is a measure of the operating performance of the properties of the Company rather than of the Company overall.
