costs. In some cases, the Company also presents (1) Property Cash NOI, which excludes observatory NOI and the effects of straight-line rent, fair value lease revenue, and straight-line ground rent expense adjustment, and (2) Property Cash NOI excluding lease termination fees. Property Cash NOI is presented solely as a supplemental disclosure that management believes allows investors to compare NOI performance across periods without taking into account the effect of certain
non-cash
rental revenues and straight-line ground rent expense adjustment. Similar to depreciation and amortization expense, fair value lease revenues, because of historical cost accounting, may distort operating performance measures at the property level. Additionally, presenting NOI excluding the impact of straight-line rent and straight-line ground rent expense adjustment provides investors with an alternative view of operating performance at the property level that more closely reflects net cash generated in the portfolio. Presenting Property Cash NOI excluding lease termination fees provides investors with additional information that allows them to compare operating performance between periods without taking into account termination fees, which can distort the results for any given period because they generally represent multiple months or years of a tenant’s rental obligations that are paid in a lump sum in connection with a negotiated early termination of the tenant’s lease and are not reflective of the core ongoing operating performance of the Company’s portfolio. However, the usefulness of NOI, Property Cash NOI, and Property Cash NOI excluding lease termination fees is limited because it excludes general and administrative costs, interest expense, depreciation and amortization expense and gains or losses from the sale of properties, and other gains and losses as stipulated by GAAP, the level of capital expenditures and leasing costs necessary to maintain the operating performance of our properties, all of which are significant economic costs. NOI and Property Cash NOI may fail to capture significant trends in these components of net income which further limits its usefulness. NOI and Property Cash NOI are measurements of the operating performance of our properties but do not measure our performance as a whole. These metrics therefore are not substitutes for net income as computed in accordance with GAAP. These measures should be analyzed in conjunction with net income computed in accordance with GAAP. Other companies may use different methods for calculating NOI, Property Cash NOI or similarly titled measures and, accordingly, our measures may not be comparable to similarly titled measures reported by other companies that do not define the measure exactly as we do.
In the Company’s analysis of NOI, particularly to make comparisons of NOI between periods meaningful, it is important to provide information for properties that were owned by the Company throughout each period presented. The Company refers to properties acquired prior to the beginning of the earliest period presented and owned by the Company through the end of the latest period presented as “Same Store.” Same Store therefore excludes properties acquired after the beginning of the earliest period presented or disposed of prior to the end of the latest period presented. Accordingly, it takes at least one year and one quarter after a property is acquired for that property to be included in Same Store. The Company’s definition of Same Store also excludes properties
or those which we otherwise expect to dispose of in the subsequent quarter and our
