24 Investors in and analysts following the real estate industry utilize funds from operations (“FFO”), net operating income (“NOI”), and earnings before interest, tax, depreciation and amortization (“EBITDA”) as supplemental performance measures. The Company believes that FFO, NOI and EBITDA are appropriate measures given their wide use by and relevance to investors and analysts. Additionally, FFO, NOI and EBITDA are commonly used in various ratios, pricing multiples, yields and returns and valuation calculations used to measure financial position, performance and value. FFO, reflecting the assumption that real estate values rise or fall with market conditions, principally adjusts for the effects of generally accepted accounting principles (“GAAP”) depreciation and amortization of real estate assets. NOI provides a measure of rental operations that does not factor in depreciation, amortization and non-property specific expenses such as general and administrative expenses. EBITDA provides a further measure to evaluate ability to incur and service debt and to fund dividends and other cash needs. FFO is defined by the National Association of Real Estate Investment Trusts (“Nareit”) as GAAP net income (loss), excluding gains (or losses) from sales of depreciable operating property, plus real estate- related depreciation and amortization, real estate related impairments, and after adjustments for nonconsolidated partnerships and joint ventures. FFO is a non-GAAP financial measure that management believes is a useful supplemental measure of the Company’s operating performance. By excluding gains and losses related to sales of previously depreciated operating real estate assets, impairment and excluding real estate asset depreciation and amortization (which can vary among owners of identical assets in similar condition based on historical cost accounting and useful life estimates), FFO provides a performance measure that, when compared period-over-period, reflects the impact to operations from trends in occupancy rates, rental rates and operating costs, providing perspective not readily apparent from GAAP net income (loss). Management believes the use of FFO has been beneficial in improving the understanding of operating results of REITs among the investing public and making comparisons of REIT operating results more meaningful. The Company also uses FFO excluding certain gain and loss items that management considers unrelated to the operational and financial performance of our core business (“Core FFO”). In addition, the Company calculates Constant Currency Core FFO by translating the operating results from the UK, Canada and Australia at the foreign currency exchange rates used for guidance. The Company believes that Core FFO and Constant Currency Core FFO provide enhanced comparability for investor evaluations of period-over-period results. The Company believes that GAAP net income (loss) is the most directly comparable measure to FFO. The principal limitation of FFO is that it does not replace GAAP net income (loss) as a performance measure or GAAP cash flow from operations as a liquidity measure. Because FFO excludes significant economic components of GAAP net income (loss) including depreciation and amortization, FFO should be used as a supplement to GAAP net income (loss) and not as an alternative to it. Furthermore, 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 is calculated in accordance with the Company’s interpretation of standards established by Nareit, which may not be comparable to FFO reported by other REITs that interpret the Nareit definition differently. NOI is derived from revenues minus property operating expenses and real estate taxes. NOI is a non-GAAP financial measure that the Company believes is helpful to investors as a supplemental 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 measure when evaluating performance and growth of particular properties and / or groups of properties. The principal limitation of NOI is that it excludes depreciation, amortization, interest expense and non-property specific expenses such as general and administrative expenses, all of which are significant costs. Therefore, NOI is a measure of the operating performance of the properties of the Company rather than of the Company overall. The Company believes that GAAP net income (loss) is the most directly comparable measure to NOI. NOI should not be considered to be an alternative to GAAP net income (loss) as an indication of the Company’s financial performance or GAAP cash flow from operating activities 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. Because of the inclusion of items such as interest, depreciation and amortization, the use of GAAP net income (loss) as a performance measure is limited as these items may not accurately reflect the actual change in market value of a property, in the case of depreciation and in the case of interest, may not necessarily be linked to the operating performance of a real estate asset, as it is often incurred at a parent company level and not at a property level. In addition, the Company calculates Constant Currency NOI for its UK Operations by translating the operating results at the foreign currency exchange rate used for guidance. The Company believes that NOI and Constant Currency NOI provide enhanced comparability for investor evaluations of period-over-period results. EBITDA as defined by Nareit (referred to as “EBITDAre”) is calculated as GAAP net income (loss), plus interest expense, plus income tax expense, plus depreciation and amortization, plus or minus losses or gains on the disposition of depreciated property (including losses or gains on change of control), plus impairment write-downs of depreciated property and of investments in nonconsolidated affiliates caused by a decrease in value of depreciated property in the affiliate, and adjustments to reflect the entity’s share of EBITDAre of nonconsolidated affiliates. EBITDAre is a non-GAAP financial measure that the Company uses to evaluate its ability to incur and service debt, fund dividends and other cash needs and cover fixed costs. Investors utilize EBITDAre as a supplemental measure to evaluate and compare investment quality and enterprise value of REITs. The Company also uses EBITDAre excluding certain gain and loss items that management considers unrelated to measurement of the Company’s performance on a basis that is independent of capital structure (“Recurring EBITDA”). The Company believes that GAAP net income (loss) is the most directly comparable measure to EBITDAre. EBITDAre is not intended to be used as a measure of the Company’s cash generated by operations or its dividend-paying capacity, and should therefore not replace GAAP net income (loss) as an indication of the Company’s financial performance or GAAP cash flow from operating, investing and financing activities as measures of liquidity.
