Copyright © 2013 Prologis Supplemental 4Q 2012 Notes and Definitions 33 FFO, as defined by Prologis, are subject to significant fluctuations from period to period FFO is not meant to represent a comprehensive system of financial reporting and does not present, nor do we intend it to present, a complete picture of our financial condition and operating performance. We believe net earnings computed under GAAP remains the primary measure of performance and that FFO is only meaningful when it is used in conjunction with net earnings computed under GAAP. Further, we believe our consolidated financial statements, prepared in accordance with GAAP, provide the most meaningful picture of our financial condition and our operating performance. NAREIT’s FFO measure adjusts net earnings computed under GAAP to exclude historical cost depreciation and gains and losses from the sales, along with impairment charges, of previously depreciated properties. We agree that these NAREIT adjustments are useful to investors for the following reasons: (i) historical cost accounting for real estate assets in accordance with GAAP assumes, through depreciation charges, that the value of real estate assets diminishes predictably over time. NAREIT stated in its White Paper on FFO “since real estate asset values have historically risen or fallen with market conditions, many industry investors have considered presentations of operating results for real estate companies that use historical cost accounting to be insufficient by themselves.” Consequently, NAREIT’s definition of FFO reflects the fact that real estate, as an asset class, generally appreciates over time and depreciation charges required by GAAP do not reflect the underlying economic realities. (ii) REITs were created as a legal form of organization in order to encourage public ownership of real estate as an asset class through investment in firms that were in the business of long-term ownership and management of real estate. The exclusion, in NAREIT’s definition of FFO, of gains and losses from the sales, along with impairment charges, of previously depreciated operating real estate assets allows investors and analysts to readily identify the operating results of the long-term assets that form the core of a REIT’s activity and assists in comparing those operating results between periods. We include the gains and losses from dispositions and impairment charges of land and development properties, as well as our proportionate share of the gains and losses from dispositions and impairment charges recognized by our unconsolidated entities, in our definition of FFO. Our FFO Measures At the same time that NAREIT created and defined its FFO measure for the REIT industry, it also recognized that “management of each of its member companies has the responsibility and authority to publish financial information that it regards as useful to the financial community.” We believe stockholders, potential investors and financial analysts who review our operating results are best served by a defined FFO measure that includes other adjustments to net earnings computed under GAAP in addition to those included in the NAREIT defined measure of FFO. Our FFO measures are used by management in analyzing our business and the performance of our properties and we believe that it is important that stockholders, potential investors and financial analysts understand the measures management uses. We use these FFO measures, including by segment and region, to: (i) evaluate our performance and the performance of our properties in comparison to expected results and results of previous periods, relative to resource allocation decisions; (ii) evaluate the performance of our management; (iii) budget and forecast future results to assist in the allocation of resources; (iv) assess our performance as compared to similar real estate companies and the industry in general; and (v) evaluate how a specific potential investment will impact our future results. Because we make decisions with regard to our performance with a long-term outlook, we believe it is appropriate to remove the effects of short-term items that we do not expect to affect the underlying long-term performance of the properties. The long-term performance of our properties is principally driven by rental income. While not infrequent or unusual, these additional items we exclude in calculating that cause both positive and negative short-term effects on our results of operations in inconsistent and unpredictable directions that are not relevant to our long-term outlook. We use our FFO measures as supplemental financial measures of operating performance. We do not use our FFO measures as, nor should they be considered to be, alternatives to net earnings computed under GAAP, as indicators of our operating performance, as alternatives to cash from operating activities computed under GAAP or as indicators of our ability to fund our cash needs. FFO, as defined by Prologis To arrive at FFO, as defined by Prologis, we adjust the NAREIT defined FFO measure to exclude: (i) deferred income tax benefits and deferred income tax expenses recognized by our subsidiaries; (ii) current income tax expense related to acquired tax liabilities that were recorded as deferred tax liabilities in an acquisition, to the extent the expense is offset with a deferred income tax benefit in GAAP earnings that is excluded from our defined FFO measure; (iii) foreign currency exchange gains and losses resulting from debt transactions between us and our foreign consolidated subsidiaries and our foreign unconsolidated entities; (iv) foreign currency exchange gains and losses from the remeasurement (based on current foreign currency exchange rates) of certain third party debt of our foreign consolidated subsidiaries and our foreign unconsolidated entities; and (v) mark-to-market adjustments associated with derivative financial instruments. We calculate FFO, as defined by Prologis for our unconsolidated entities on the same basis as we calculate our FFO, as defined by Prologis. We believe investors are best served if the information that is made available to them allows them to align their analysis and evaluation of our operating results along the same lines that our management uses in planning and executing our business strategy. Core FFO In addition to FFO, as defined by Prologis, we also use Core FFO. To arrive at Core FFO, we adjust FFO, as defined by Prologis, to exclude the following recurring and non-recurring items that we recognized directly or our share recognized by our unconsolidated entities to the extent they are included in FFO, as defined by Prologis: (i) gains or losses from acquisition, contribution or sale of land or development properties; (ii) income tax expense related to the sale of investments in real estate; (iii) impairment charges recognized related to our investments in real estate (either directly or through our investments in unconsolidated entities) generally as a result of our change in intent to contribute or sell these properties; (iv) impairment charges of goodwill and other assets; (v) gains or losses from the early extinguishment of debt; (vi) merger, acquisition and other integration expenses; and (vii) expenses related to natural disasters. We believe it is appropriate to further adjust our FFO, as defined by Prologis for certain recurring items as they were driven by transactional activity and factors relating to the financial and real estate markets, rather than factors specific to the on-going operating performance of our properties or investments. The impairment charges we recognized were primarily based on valuations of real estate, which had declined due to market conditions, that we no longer expected to hold for long- term investment. We currently have and have had over the past several years a stated priority to strengthen our financial position. We expect to accomplish this by reducing our debt, our investment in certain low yielding assets, such as land that we decide not to develop and our exposure to foreign currency exchange fluctuations. As a result, we have sold to third parties or contributed to unconsolidated entities real estate properties that, depending on market conditions, might result in a gain or loss. The impairment charges related to goodwill and other assets that we have recognized were similarly caused by the decline in the real estate markets. Also in connection with our stated priority to reduce debt and extend debt maturities, we have purchased portions of |
