SUPPLEMENTAL DEFINITIONS

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

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.

Debt to Market Capitalization Ratio - Debt to Market Capitalization is a non-GAAP measure that is calculated as the Company’s estimated market value based upon the quarter-end trading price of the Company’s common stock multiplied by all common shares and operating partnership units outstanding plus the face value of the Company’s preferred equity divided by consolidated debt.

Fixed charge - Total payments for interest, principal amortization, ground leases and preferred stock dividend.

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

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.

Funds from Operations (FFO) - FFO is a widely recognized non-GAAP measure of REIT performance. The Company computes FFO in accordance with standards established by the National Association of Real Estate Investment Trusts, or 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 Generally Accepted Accounting Principles, or 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.

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.

Junior Mortgage Participations - Subordinate interests in first mortgages.

Mezzanine Debt Loans - Loans secured by ownership interests.

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 calculated by subtracting free rent (net of amortization), straight-line rent, FAS 141 rental income from NOI, while adding ground lease straight-line adjustment and the allowance for straight-line tenant credit loss.

Percentage leased - The percentage of leased square feet, including month-to-month leases, to total rentable square feet owned, as of the date reported. Space is considered leased when the tenant has either taken physical or economic occupancy.

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

Recurring capital expenditures - Non-incremental 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 standard.”

Redevelopment costs - Non-recurring capital expenditures incurred in order to improve buildings to SLG’s “operating standards.” These building costs are taken into consideration during the underwriting for a given property’s acquisition.

Same-Store Properties (Same-Store) - Same-Store refers to properties owned in the same manner during both the current and prior year, and excludes development properties prior to being stabilized for both the current and prior year.

Second generation TIs and LCs - Tenant improvements, lease commissions, and other leasing costs incurred during leasing of second generation space. Costs incurred prior to leasing available square feet are not included until such space is leased. Second generation space excludes square footage vacant at acquisition.

SLG’s share of total debt to market capitalization - SLG’s share of total debt divided by the sum of total debt plus market equity and preferred stock at liquidation value. SLG’s share of total debt includes total consolidated debt plus SLG’s pro rata share of the debt of unconsolidated joint ventures. Market equity assumes conversion of all OP units into common stock.

Total square feet owned - The total square footage of properties either owned directly by SLG or in which SLG has an interest (e.g. joint ventures).

(1) Net of unamortized fees, discounts, and premiums.
(2) Excludes loans secured by the leasehold interest in 2 Herald Square which were in maturity default at the time of acquisition in April and May 2017. The loans were put on non-accrual in August 2017 when one of the investors in the borrower did not repay the loan notwithstanding the approval to do so rendered by a court in a litigation separate from the foreclosure. No impairment was recorded as the Company believes that the fair value of the property exceeds the carrying amount of the loans. The loans had an outstanding balance including accrued interest of $259.3 million at the time that they were put on non accrual status.
(3) Reflects the last dollar of exposure to the Company's most junior position.
(4) Calculated based on accounting income, which includes cash interest, paid-in-kind interest, fee accrual and amortization of discounts, recognized in the last month of the quarter, excluding accelerated fee income resulting from early repayment.

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 calculated by subtracting free rent (net of amortization), straight-line rent, FAS 141 rental income 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.

Debt to Market Capitalization Ratio

Debt to Market Capitalization is a non-GAAP measure that is calculated as the Company’s estimated market value based upon the quarter-end trading price of the Company’s common stock multiplied by all common shares and operating partnership units outstanding plus the face value of the Company’s preferred equity divided by consolidated debt.

The Company presents the ratio of debt to market capitalization as a measure of the Company’s leverage position relative to the Company’s estimated market value. The Company believes this ratio may provide investors with another measure of the Company’s current leverage position. The debt to market capitalization ratio should be used as one measure of the Company’s leverage position, and this measure is commonly used in the REIT sector; however, such measure may not be comparable to those used by other REITs that do not compute such measure in the same manner. The debt to market capitalization ratio does not represent the Company’s borrowing capacity and should not be considered an alternative measure to the Company’s current lending arrangements.

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

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).
