Funds From Operations (FFO) (dollars in thousands, except per share amounts) 5 Q4 2017 Supplemental Operating & Financial Data The following is a reconciliation of net income available to common stockholders (which we believe is the most comparable GAAP measure) to FFO. Also presented is information regarding distributions paid to common stockholders and the weighted average number of common shares used for the basic and diluted FFO per share computations. We define FFO, a non-GAAP measure, consistent with the National Association of Real Estate Investment Trusts’ (NAREIT’s) definition, as net income available to common stockholders, plus depreciation and amortization of real estate assets, plus impairments of depreciable real estate assets, and reduced by gains on property sales. Presentation of the information regarding FFO and AFFO (described on page 6) is intended to assist the reader in comparing the operating performance of different REITs, although it should be noted that not all REITs calculate FFO and AFFO in the same way, so comparisons with other REITs may not be meaningful. FFO and AFFO should not be considered as alternatives to reviewing our cash flows from operating, investing, and financing activities. In addition, FFO and AFFO should not be considered as measures of liquidity, of our ability to make cash distributions, or of our ability to pay interest payments.

Adjusted Funds From Operations (AFFO) (dollars in thousands, except per share amounts) 6 Q4 2017 Supplemental Operating & Financial Data The following is a reconciliation of net income available to common stockholders (which we believe is the most comparable GAAP measure) to FFO and AFFO. Also presented is information regarding distributions paid to common stockholders and the weighted average number of common shares used for the basic and diluted AFFO per share computations. We define AFFO as FFO adjusted for unique revenue and expense items, which the company believes are not as pertinent to the measurement of the company’s ongoing operating performance. Most companies in our industry use a similar measurement to AFFO, but they may use the term "CAD" (for Cash Available for Distribution) or "FAD" (for Funds Available for Distribution).

It includes, at our election, two six-month extension options, at a cost of 0.075% of the facility commitment, or $1.5 million per option. The credit facility also has a $1.0 billion expansion option. As of December 31, 2017, approximately $1.89 billion was available on the credit facility. As of December 31, 2017, the entirety of the credit facility balance was borrowed under our Swingline Loan subfacility, which accrued interest at the Base Rate of 4.50%. On January 3, 2018, we converted the Base Rate Loan to a LIBOR Loan, which bears interest at one month LIBOR plus 0.85%. The Swingline Loan was outstanding for five calendar days. (2) In December 2017, in conjunction with the acquisition of a portfolio of properties, we entered into a $125.9 million promissory note, which was paid in full at maturity during January 2018. (3) Borrowing under the term loan bears interest at the current one month LIBOR plus 1.10%. We have an interest rate swap which essentially fixes our per annum interest rate on the term loan at 2.05%. In January 2018 we entered into a six month extension of this loan, which now matures in July 2018 and includes, at our election, two six-month extensions options. Upon extension, we terminated the interest rate swap and the borrowing rate was reduced to LIBOR plus 0.90%. (4) Borrowing under the term loan bears interest at the current one month LIBOR plus 0.90%. We have an interest rate swap which essentially fixes our per annum interest rate on the term loan at 2.62%. (5) The mortgages payable are at fixed interest rates, except for mortgages totaling $22.4 million as of December 31, 2017. (6) Excludes non-cash unamortized net original issuance premiums recorded on the senior unsecured notes and bonds, as well as non-cash unamortized net premiums recorded on the mortgages payable, and deferred financing costs on the term loans, notes and bonds, and mortgages payable.

Debt Service Coverage (4) Fixed Charge Coverage (5) Adjusted EBITDA & Coverage Ratios (dollars in thousands) 11 Q4 2017 Supplemental Operating & Financial Data Reconciliation of Net Income to Adjusted EBITDA (1) Three months ended December 31, 2017 Net income $ 60,952 Interest (2) 103,903 Income taxes 3,424 Depreciation and amortization 127,033 Impairment loss 6,679 Gain on sales of real estate (23,208) Quarterly Adjusted EBITDA $ 278,783 Annualized Adjusted EBITDA $ 1,115,132 Debt/Adjusted EBITDA (3) 5.5 (1) Adjusted EBITDA, a non-GAAP measure, means, for the most recent quarter, annualized earnings (net income) before (i) interest expense, including non-cash loss (gain) on swaps, (ii) income and franchise taxes, (iii) real estate depreciation and amortization, (iv) impairment losses, (v) gain on sales, and (vi) loss on extinguishment of debt. Our adjusted EBITDA may not be comparable to adjusted EBITDA reported by other companies that interpret the definitions of adjusted EBITDA differently than we do. Management believes adjusted EBITDA to be a meaningful measure of a REIT’s performance because it is widely followed by industry analysts, lenders and investors. Management also believes the use of an annualized quarterly adjusted EBITDA metric is meaningful because it represents the Company’s current earnings run rate for the period presented. The ratio of our total debt to our annualized quarterly adjusted EBITDA is also used to determine vesting of performance share awards granted to our executive officers. Adjusted EBITDA should be considered along with, but not as an alternative to, net income as a measure of our operating performance. (2) Interest expense includes the $42,426 loss on extinguishment of debt resulting from the early redemption of our $550 million of outstanding 6.75% notes due August 2019. (3) Our ratio of debt to adjusted EBITDA, which is used by management as a measure of leverage, is calculated by annualizing quarterly adjusted EBITDA and then dividing by our total debt per the consolidated balance sheet. (4) Refer to footnote 1 on page 12 for a detailed description of the calculation of debt service coverage. (5) Fixed charge coverage is calculated in exactly the same manner as the debt service coverage (which is calculated on page 12), except that preferred stock dividends are also added to the denominator. Since we redeemed our Class F preferred stock in April 2017, our fixed charge coverage is equivalent to our debt service coverage. 4.8 4.1 4.4 4.7 4.8 0.0 0.5 1.0 1.5 2.0 2.5 3.0 3.5 4.0 4.5 5.0 5.5 Q4 2016 Q1 2017 Q2 2017 Q3 2017 Q4 2017 4.2 4.1 4.4 4.7 4.8 0.0 0.5 1.0 1.5 2.0 2.5 3.0 3.5 4.0 4.5 5.0 5.5 Q4 2016 Q1 2017 Q2 2017 Q3 2017 Q4 2017

Debt Covenants 12 Q4 2017 Supplemental Operating & Financial Data As of December 31, 2017 The following is a summary of the key financial covenants for our senior unsecured notes and bonds, as defined and calculated per their terms. These calculations, which are not based on U.S. GAAP measurements, are presented to investors to show our ability to incur additional debt under the terms of our senior unsecured notes and bonds as well as to disclose our current compliance with such covenants, and are not measures of our liquidity or performance. Required Actuals Limitation on incurrence of total debt < 60% of adjusted undepreciated assets 40.6% Limitation on incurrence of secured debt < 40% of adjusted undepreciated assets 2.2% Debt service and fixed charge coverage (trailing 12 months) (1) > 1.5 x 4.8x Maintenance of total unencumbered assets > 150% of unsecured debt 249.6% (1) Our debt service coverage ratio is calculated on a pro forma basis for the preceding four-quarter period on the assumptions that: (i) the incurrence of any Debt (as defined in the covenants) incurred by us since the first day of such four-quarter period and the application of the proceeds therefrom (including to refinance other Debt since the first day of such four quarter period), (ii) the repayment or retirement of any of our Debt since the first day of such four-quarter period, and (iii) any acquisition or disposition by us of any asset or group since the first day of such four quarters had in each case occurred on January 1, 2017, and subject to certain additional adjustments. Such pro forma ratio has been prepared on the basis required by that debt service covenant, reflects various estimates and assumptions and is subject to other uncertainties, and therefore does not purport to reflect what our actual debt service coverage ratio would have been had transactions referred to in clauses (i), (ii) and (iii) of the preceding sentence occurred as of January 1, 2017, nor does it purport to reflect our debt service coverage ratio for any future period. Our fixed charge coverage is calculated in exactly the same manner as our debt service coverage, except that preferred stock dividends are also added to the denominator; since we redeemed our Class F preferred dividends in April 2017, our fixed charge coverage ratio is equivalent to our debt service coverage.
