Supplemental Information 3 Fourth Quarter 2018

SUPPLEMENTAL DEFINITIONS

Annualized cash rent - Monthly base rent and escalations per the lease, as of a certain date, multiplied by 12.

Capitalized Interest - The total of i) interest cost for project specific debt on properties that are under development or redevelopment plus ii) an imputed interest cost for properties that are under development or redevelopment, which is calculated based on the Company’s equity investment in those properties multiplied by the Company’s weighted average corporate borrowing cost.  Capitalized Interest is a component of the book basis in a development or redevelopment property.

Debt service coverage - Operating Income plus income taxes, loan loss reserves and our share of joint venture depreciation and amortization, divided by total interest and principal payments.

Earnings Before Interest, Taxes, Depreciation and Amortization for Real Estate (EBITDAre) - EBITDAre is a non-GAAP financial measure. The Company computes EBITDAre in accordance with standards established by the National Association of Real Estate Investment Trusts, or NAREIT, which may not be comparable to EBITDAre reported by other REITs that do not compute EBITDAre in accordance with the NAREIT definition, or that interpret the NAREIT definition differently than the Company does. The White Paper on EBITDAre approved by the Board of Governors of NAREIT in September 2017 defines EBITDAre as net income (loss) (computed in accordance with Generally Accepted Accounting Principles, or GAAP), plus interest expense, plus income tax expense, plus depreciation and amortization, plus (minus) losses and gains on the disposition of depreciated property, plus impairment write-downs of depreciated property and investments in unconsolidated joint ventures, plus adjustments to reflect the entity's share of EBITDAre of unconsolidated joint ventures.

First generation TIs and LCs - Tenant improvements (TIs), leasing commissions (LCs), and other leasing costs that were taken into consideration when underwriting the acquisition of a property.

Fixed charge - Total payments for interest, loan principal amortization, ground rent and preferred stock dividends.

Fixed charge coverage - Operating Income plus income taxes, loan loss reserves and our share of joint venture depreciation and amortization, divided by Fixed Charge.

Funds Available for Distribution (FAD) - 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 ground rent, non-cash deferred compensation, and a pro-rata adjustment for FAD for SLG’s unconsolidated JV, less straight line rental income, free rent net of amortization, second cycle tenant improvement and leasing costs, and recurring building improvements.

Funds from Operations (FFO) - FFO is a widely recognized non-GAAP financial measure of REIT performance. The Company computes 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 the Company does. The revised White Paper on FFO approved by the Board of Governors of NAREIT in April 2002, and subsequently amended, defines FFO as net income (loss) (computed in accordance with GAAP), excluding gains (or losses) from sales of properties, debt restructurings and real estate related impairment charges, plus real estate related depreciation and amortization and after adjustments for unconsolidated partnerships and joint ventures.

Junior Mortgage Participations - Subordinate interests in first mortgages.

Mezzanine Debt - Loans secured by ownership interests in real estate.

Net Operating Income (NOI) and Cash NOI - 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 amortization of acquired above and below-market leases, net from NOI, while adding ground lease straight-line adjustment and the allowance for straight-line tenant credit loss.

Preferred Equity Investments - Equity investments that are senior to common equity and are entitled to preferential returns.

Recurring capital expenditures - Building improvements and leasing costs required to maintain current revenues. Recurring capital expenditures do not include immediate building improvements that were taken into consideration when underwriting the purchase of a building or which are incurred to bring a building up to “operating standards.”

Redevelopment costs - Non-recurring capital expenditures incurred to improve buildings to SLG’s “operating standards.”

Same-Store Properties (Same-Store) - Properties owned in the same manner during both the current and prior year, excluding development properties that are not stabilized for both the current and prior year. Changes to Same-Store properties in 2018 were as follows:

Added to Same-Store in 2018:	Removed from Same-Store in 2018:
11 Madison Avenue	600 Lexington Avenue (sold)
10 East 53rd Street	609 Fifth Avenue (in redevelopment)
1552-1560 Broadway	635 Madison (sold)
605 West 42nd Street	1745 Broadway (sold)
115 Spring Street	115-117 Stevens Avenue (sold)
400 East 57th Street	Reckson Executive Park (sold)
	724 Fifth Avenue (sold)
	3 Columbus Circle (sold)

Second generation TIs and LCs - Tenant improvements, leasing commissions, and other leasing costs that do not meet the definition of first generation TIs and LCs. Costs incurred prior to leasing available square feet are not included until such space is leased.

Total square feet owned - The total square footage of properties either owned directly by SLG or in which SLG has a joint venture interest.

Non-GAAP Disclosures and Reconciliations Unaudited (Dollars in Thousands, except per share data)

Funds Available for Distribution (FAD)

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 ground rent, non-cash deferred compensation, and a pro-rata adjustment for FAD for SLG’s unconsolidated JV, less straight line rental income, free rent net of amortization, second cycle tenant improvement and leasing costs, and recurring building improvements.

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 the Company believes it provides useful information regarding the Company’s ability to fund its dividends. 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.

Earnings Before Interest, Taxes, Depreciation and Amortization (EBITDAre)

EBITDAre is a non-GAAP financial measure. The Company computes EBITDAre in accordance with standards established by the National Association of Real Estate Investment Trusts, or NAREIT, which may not be comparable to EBITDAre reported by other REITs that do not compute EBITDAre in accordance with the NAREIT definition, or that interpret the NAREIT definition differently than the Company does. The White Paper on EBITDAre approved by the Board of Governors of NAREIT in September 2017 defines EBITDAre as net income (loss) (computed in accordance with Generally Accepted Accounting Principles, or GAAP), plus interest expense, plus income tax expense, plus depreciation and amortization, plus (minus) losses and gains on the disposition of depreciated property, plus impairment write-downs of depreciated property and investments in unconsolidated joint ventures, plus adjustments to reflect the entity's share of EBITDAre of unconsolidated joint ventures.

The Company presents EBITDAre because the Company believes that EBITDAre, along with cash flow from operating activities, investing activities and financing activities, provides investors with an additional indicator of the Company’s ability to incur and service debt. EBITDAre 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.

Net Operating Income (NOI) and Cash NOI

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 amortization of acquired above and below-market leases, net from NOI, while adding ground lease straight-line adjustment and the allowance for straight-line tenant credit loss.

The Company presents NOI and Cash NOI because the Company believes that these measures, when taken together with the corresponding GAAP financial measures and our reconciliations, provide investors with meaningful information regarding the operating performance of 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. The Company uses 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.

Coverage Ratios

The Company presents fixed charge and debt service coverage ratios to provide a measure of the Company’s financial flexibility to service current debt amortization, interest expense and ground rent from current cash net operating income. These coverage ratios represent a common measure of the Company’s ability to service fixed cash payments; however, these ratios are not used as an alternative to cash flow from operating, financing and investing activities (determined in accordance with GAAP).
