Notes:

Funds from Operations

Funds from Operations, or FFO, is a widely recognized non-GAAP financial measure of REIT performance. We compute FFO in accordance with standards established by NAREIT, which may not be comparable to FFO reported by other REITs that do not compute FFO in accordance with the NAREIT definition, or that interpret the NAREIT definition differently than we do. The revised White Paper on FFO approved by the Board of Governors of NAREIT in April 2002, and subsequently amended in December 2018, defines FFO as net income (loss) (computed in accordance with GAAP), excluding gains (or losses) from sales of properties, and real estate related impairment charges, plus real estate related depreciation and amortization and after adjustments for unconsolidated partnerships and joint ventures.

We present FFO because we consider it an important supplemental measure of our operating performance and believe that it is frequently used by securities analysts, investors and other interested parties in the evaluation of REITs, particularly those that own and operate commercial office properties. We also use FFO as one of several criteria to determine performance-based compensation for members of its senior management. FFO is intended to exclude GAAP historical cost depreciation and amortization of real estate and related assets, which assumes that the value of real estate assets diminishes ratably over time. Historically, however, real estate values have risen or fallen with market conditions. Because FFO excludes depreciation and amortization unique to real estate, gains and losses from property dispositions, and real estate related impairment charges, it provides a performance measure that, when compared year over year, reflects the impact to operations from trends in occupancy rates, rental rates, operating costs, and interest costs, providing perspective not immediately apparent from net income. FFO does not represent cash generated from operating activities in accordance with GAAP and should not be considered as an alternative to net income (determined in accordance with GAAP), as an indication of our financial performance or to cash flow from operating activities (determined in accordance with GAAP) as a measure of our liquidity, nor is it indicative of funds available to fund our cash needs, including our ability to make cash distributions.

Funds Available for Distribution

Funds Available for Distribution, or FAD, is a non-GAAP financial measure that is calculated as FFO plus non-real estate depreciation, allowance for straight line credit loss, adjustment for straight line operating lease rent, non-cash deferred compensation, and pro-rata adjustments for these items from the Company’s unconsolidated JVs, less straight line rental income, free rent net of amortization, second generation tenant improvement and leasing costs, and recurring capital expenditures.

FAD is not intended to represent cash flow for the period and is not indicative of cash flow provided by operating activities as determined in accordance with GAAP. FAD is presented solely as a supplemental disclosure with respect to liquidity. Because all companies do not calculate FAD the same way, the presentation of FAD may not be comparable to similarly titled measures of other companies. FAD does not represent cash flow from operating, investing and finance activities in accordance with GAAP and should not be considered as an alternative to net income (determined in accordance with GAAP), as an indication of the Company’s financial performance, as an alternative to net cash flows from operating activities (determined in accordance with GAAP), or as a measure of the Company’s liquidity.

Same-Store Cash Net Operating Income

Net Operating Income, or NOI, is a non-GAAP financial measure that is calculated as operating income before transaction related costs, gains/losses on early extinguishment of debt, marketing general and administrative expenses and non-real estate revenue. Cash NOI is also a non-GAAP financial measure that is calculated by subtracting free rent (net of amortization), straight-line rent, and the amortization of acquired above and below-market leases from NOI, while adding operating lease straight-line adjustment and the allowance for straight-line tenant credit loss.

We present NOI and Cash NOI because we believe that these measures, when taken together with the corresponding GAAP financial measures and reconciliations, provide investors with meaningful information regarding the operating performance of our properties. When operating performance is compared across multiple periods, the investor is provided with information not immediately apparent from net income that is determined in accordance with GAAP. NOI and Cash NOI provide information on trends in the revenue generated and expenses incurred in operating our properties, unaffected by the cost of leverage, straight-line adjustments, depreciation, amortization, and other net income components. We use these metrics internally as performance measures. None of these measures is an alternative to net income (determined in accordance with GAAP) and same-store performance should not be considered an alternative to GAAP net income performance.

Same-Store refers to properties owned in the same manner during both the current and prior year, excluding development and redevelopment properties that are not stabilized for both the current and prior year.

SLG Share of Unconsolidated JV is computed by multiplying the referenced line item by the Company’s percentage ownership or economic interest in the respective joint ventures and may not accurately depict the legal and economic implications of holding a non-controlling interest in the respective joint ventures.
