42 RECONCILIATIONS OF NON-GAAP FINANCIALMEASURES AND OTHER TERMS ADJUSTED EBITDA RECONCILIATION Adjusted EBITDA (earnings before interest, taxes, depreciation, and amortization) is a component of the credit ratio, "Net Indebtedness Divided by Adjusted EBITDA", presented on page S-6 of the earnings supplement for the second quarter of 2017, in the section titled "Selected Credit Ratios", and it is not intended to be a measure of free cash flow for our management’s discretionary use, as it does not consider certain cash requirements such as income tax payments, debt service requirements, capital expenditures and other fixed charges. Adjusted EBITDA is not a recognized measurement under U.S. generally accepted accounting principles ("GAAP"). Because not all companies use identical calculations, our presentation of Adjusted EBITDA may not be comparable to similarly titled measures of other companies. The reconciliation of Adjusted EBITDA to Net Income available to common stockholders is presented in the table below (Dollars in thousands): Three Months Ended June 30, 2017 Net income available to common stockholders $ 70,759 Add: Net income attributable to noncontrolling interest 5,036 Net Income 75,795 Adjustments: Acquisition and investment related costs 274 Depreciation and amortization 117,939 Equity income from co-investments (4,395) Gain on sale of marketable securities (13) Gain on remeasurement of co-investment (2,159) Income from early redemption of preferred equity investments (248) Interest expense, net (1) 54,281 Adjusted EBITDA $ 241,474 (1) Interest expense, net includes items such as gains on derivatives and the amortization of deferred charges. ENCUMBEREDEncumbrance means any mortgage, deed of trust, lien, charge, pledge, security interest, security agreement or other encumbrance of any kind.

43 RECONCILIATIONS OF NON-GAAP FINANCIALMEASURES AND OTHER TERMS FUNDS FROM OPERATIONS (“FFO”) FFO, as defined by the National Association of Real Estate Investment Trusts (“NAREIT”), is generally considered by industry analysts as an appropriate measure of performance of an equity REIT. Generally, FFO adjusts the net income of equity REITs for non-cash charges such as depreciation and amortization of rental properties, impairment charges, gains on sales of real estate and extraordinary items. Management considers FFO and FFO which excludes merger, integration and acquisition costs and items that are not routine or not related to the Company’s core business activities, which is referred to as “Core FFO”, to be useful financial performance measurements of an equity REIT because, together with net income and cash flows, FFO and Core FFO provide investors with additional bases to evaluate the operating performance and ability of a REIT to incur and service debt and to fund acquisitions and other capital expenditures and the ability to pay dividends.FFO and Core FFO do not represent net income or cash flows from operations as defined by GAAP and are not intended to indicate whether cash flows will be sufficient to fund cash needs. These measures should not be considered as an alternative to net income as an indicator of the REIT's operating performance or to cash flows as a measure of liquidity. FFO and Core FFO do not measure whether cash flow is sufficient to fund all cash needs including principal amortization, capital improvements and distributions to shareholders. FFO and Core FFO do not represent cash flows generated from operating, investing or financing activities as defined under GAAP. Management has consistently applied the NAREIT definition of FFO to all periods presented. However, there is judgment involved and other REITs’ calculation of FFO may vary from the NAREIT definition for this measure, and thus their disclosures of FFO may not be comparable to the Company’s calculation. The reconciliations of diluted FFO and Core FFO are detailed on page S-3 of the earnings supplement for the second quarter of 2017 in the section titled "Consolidated Funds From Operations".INTEREST EXPENSE, NETInterest expense, net is presented on page S-1 titled "Consolidated Operating Results". Interest expense, net includes items such as gains on derivatives and the amortization of deferred charges and is presented in the table below (Dollars in thousands): Three Months Ended Six Months Ended June 30, 2017 June 30, 2017 Interest expense $ 56,812 $ 111,395 Adjustments: Total return swap income (2,531) (5,115) Interest expense, net $ 54,281 $ 106,280

This credit ratio is calculated by dividing net indebtedness by Adjusted EBITDA, as annualized based on the most recent quarter, and adjusted for estimated net operating income from properties acquired or disposed of during the quarter. This ratio is presented by the Company because it provides rating agencies and investors an additional means of comparing the Company's ability to service debt obligations to that of other companies. Net indebtedness is total debt, net less unamortized premiums, discounts, debt issuance costs, unrestricted cash and cash equivalents, and marketable securities. The reconciliation of Adjusted EBITDA is set forth in "Adjusted EBITDA Reconciliation" above. The calculation of this credit ratio and a reconciliation of net indebtedness to total debt, net is presented in the following table (Dollars in thousands): Based on the amount for the most recent quarter, multiplied by four.Adjustments made for properties acquired or disposed of during the quarter, multiplied by four.

45 NET OPERATING INCOME (“NOI”) AND SAME-PROPERTY NOI RECONCILIATIONSNet Operating Income ("NOI") and same-property NOI are considered by management to be important supplemental performance measures to earnings from operations included in the Company’s consolidated statements of income. The presentation of same-property NOI assists with the presentation of the Company’s operations prior to the allocation of depreciation and any corporate-level or financing-related costs. NOI reflects the operating performance of a community and allows for an easy comparison of the operating performance of individual communities or groups of communities. In addition, because prospective buyers of real estate have different financing and overhead structures, with varying marginal impacts to overhead by acquiring real estate, NOI is considered by many in the real estate industry to be a useful measure for determining the value of a real estate asset or group of assets. The Company defines same-property NOI as same-property revenue less same-property operating expenses, including property taxes. Please see the reconciliation of earnings from operations to NOI and same-property NOI, which in the table below is the NOI for stabilized properties consolidated by the Company for the periods presented (Dollars in thousands): RECONCILIATIONS OF NON-GAAP FINANCIALMEASURES AND OTHER TERMS Three Months Ended Three Months Ended Six Months Ended Six Months Ended June 30, June 30, June 30, June 30, 2017 2016 2017 2016 Earnings from operations $ 112,247 $ 105,873 $ 221,478 $ 205,868 Adjustments: Depreciation and amortization 117,939 109,673 233,442 219,380 Management and other fees from affiliates (2,296) (2,028) (4,532) (4,052) General and administrative 10,337 9,698 20,938 18,880 Acquisition and investment related costs 274 267 830 1,095 NOI 238,501 223,483 472,156 441,171 Less: Non-same property NOI (24,147) (18,783) (46,132) (36,018) Same-Property NOI $ 214,354 $ 204,700 $ 426,024 $ 405,153

46 PUBLIC BOND COVENANTSPublic Bond Covenants refers to certain covenants set forth in instruments governing the Company's unsecured indebtedness. These instruments require the Company to meet specified financial covenants, including covenants relating to net worth, fixed charge coverage, debt service coverage, the amounts of total indebtedness and secured indebtedness, leverage and certain investment limitations. These covenants may restrict the Company's ability to expand or fully pursue its business strategies. The Company's ability to comply with these covenants may be affected by changes in the Company's operating and financial performance, changes in general business and economic conditions, adverse regulatory developments or other events adversely impacting it. The breach of any of these covenants could result in a default under the Company's indebtedness, which could cause those and other obligations to become due and payable. If any of the Company's indebtedness is accelerated, it may not be able to repay it. For risks related to failure to comply with these covenants, see "Item 1A: Risk Factors - Risks Related to Our Indebtedness and Financing" in the Company's annual report on Form 10-K and other reports filed by the Company with the SEC.The ratios set forth on page S-6 of the earnings supplement for the second quarter of 2017 in the section titled "Public Bond Covenants" are provided only to show the Company's compliance with certain specified covenants that are contained in indentures related to the Company's issuance of Senior Notes, which indentures are filed by the Company with the SEC. See, for example, the Indenture dated April 10, 2017, filed by the Company as Exhibit 4.1 to the Company's Form 8-K, filed on April 10, 2017. These ratios should not be used for any other purpose, including without limitation to evaluate the Company's financial condition or results of operations, nor do they indicate the Company's covenant compliance as of any other date or for any other period. The capitalized terms in the disclosure are defined in the indentures filed by the Company with the SEC and may differ materially from similar terms used by other companies that present information about their covenant compliance.SECURED DEBTSecured Debt means Debt of the Company or any of its subsidiaries which is secured by an encumbrance on any property or assets of the Company or any of its subsidiaries. The calculation of Secured Debt is set forth on page S-5 of the earnings supplement for the second quarter of 2017. RECONCILIATIONS OF NON-GAAP FINANCIALMEASURES AND OTHER TERMS

47 RECONCILIATIONS OF NON-GAAP FINANCIALMEASURES AND OTHER TERMS UNENCUMBERED NOI TO ADJUSTED TOTAL NOIThis ratio is presented on page S-6 of the earnings supplement for the second quarter of 2017 in the section titled "Selected Credit Ratios". Unencumbered NOI means the sum of NOI for those real estate assets which are not subject to an Encumbrance securing Debt. The ratio of Unencumbered NOI to Adjusted Total NOI for the three months ended June 30, 2017, annualized, is calculated by dividing Unencumbered NOI, annualized for the three months ended June 30, 2017 and as further adjusted for pro forma NOI for properties acquired or sold during the recent quarter, by Adjusted Total NOI as annualized. The calculation and reconciliation of NOI is set forth in "Net Operating Income ("NOI") and Same-Property NOI Reconciliation." This ratio is presented by the Company because it provides rating agencies and investors an additional means of comparing the Company's ability to service debt obligations to that of other companies. The calculation of this ratio is presented in the table below (Dollars in thousands): Annualized Q2'17 (1) NOI $ 954,004 Adjustments: Other, net (2) (11,915) Adjusted Total NOI 942,089 Less: Encumbered NOI (288,159) Unencumbered NOI $ 653,930 Encumbered NOI $ 288,159 Unencumbered NOI 653,930 Adjusted Total NOI $ 942,089 Unencumbered NOI to Adjusted Total NOI 69% This table is based on the amounts for the most recent quarter, multiplied by four.Includes intercompany eliminations pertaining to self-insurance and other expenses.
