LEGISLATION UPDATE * Housing costs remain a key political and business issue across the country with many states implementing rent control legislation including Oregon, Colorado, Florida, Illinois, Massachusetts, and New York. New York landlords are currently challenging the constitutionality of the state’s rent control regulation in Federal Court.A more balanced discussion is happening in California to address the state’s chronic housing shortage. As of early September 2019, AB 1482 would cap renewal rents at CPI + 5%, providing renter protections while maintaining the incentive for new home development “Since 2005 California has only produced 308 housing units for every 1,000 new residents. Add in the fact that California will be home to 50 million people by 2050, and it’s obvious we’re not on pace to meet that demand…we need to generate more funding for affordable housing, implement regulatory reform and create new financial incentives” – Governor Newsom If approval rates continue as they have during the first half of the year, the state is on track to approve just 107,000 housing units this year, far less than the state would need to build to reach Newsom’s goal.

ADJUSTED EBITDAre RECONCILIATION The National Association of Real Estate Investment Trusts ("NAREIT”) defines earnings before interest, taxes, depreciation and amortization for real estate ("EBITDAre") (September 2017 White Paper) as net income (computed in accordance with U.S. generally accepted accounting principles ("U.S. GAAP")” before interest expense, income taxes, depreciation and amortization expense, and further adjusted for gains and losses from sales of depreciated operating properties, impairment write-downs of depreciated operating properties, impairment write-downs of investments in unconsolidated entities caused by a decrease in value of depreciated operating properties within the joint venture and adjustments to reflect the Company’s share of EBITDAre of investments in unconsolidated entities. The Company believes that EBITDAre is useful to investors, creditors and rating agencies as a supplemental measure of the Company’s ability to incur and service debt because it is a recognized measure of performance by the real estate industry, and by excluding gains or losses related to sales or impairment of depreciated operating properties, EBITDAre can help compare the Company’s credit strength between periods or as compared to different companies.Adjusted EBITDAre represents EBITDAre further adjusted for non-comparable items and is a component of the credit ratio, "Net Indebtedness Divided by Adjusted EBITDAre, normalized and annualized," presented on page S-6 of the earnings supplement for the second quarter of 2019, in the section titled "Selected Credit Ratios," and it is not intended to be a measure of free cash flow for 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 EBITDAre is an important metric in evaluating the credit strength of the Company and its ability to service its debt obligations. The Company believes that Adjusted EBITDAre is useful to investors, creditors and rating agencies because it allows investors to compare the Company’s credit strength to prior reporting periods and to other companies without the effect of items that by their nature are not comparable from period to period and tend to obscure the Company’s actual credit quality.EBITDAre and Adjusted EBITDAre are not recognized measurements under U.S. GAAP. Because not all companies use identical calculations, the Company's presentation of EBITDAre and Adjusted EBITDAre may not be comparable to similarly titled measures of other companies. RECONCILIATIONS OF NON-GAAP FINANCIAL MEASURES AND OTHER TERMS *

ADJUSTED EBITDAre RECONCILIATION (CONTINUED)The reconciliations of Net Income available to common stockholders to EBITDAre and Adjusted EBITDAre are presented in the table below (Dollars in thousands): RECONCILIATIONS OF NON-GAAP FINANCIAL MEASURES AND OTHER TERMS (1) Interest expense, net includes items such as gains on derivatives and the amortization of deferred charges. * Three Months Ended June 30, 2019 Net income available to common stockholders $ 92,275 Adjustments: Net income attributable to noncontrolling interest 5,786 Interest expense, net (1) 52,137 Depreciation and amortization 119,465 Income tax provision 50 Gain on sale of co-investment communities (870) Co-investment EBITDAre adjustments 21,805 EBITDAre 290,648 Gain on sale of marketable securities (556) Unrealized losses on marketable securities 56 Insurance reimbursements and legal settlements, net (38) Income from early redemption of preferred equity investments (732) Expensed acquisition and investment related costs 24 Gain on early retirement of debt, net (332) Adjusted EBITDAre $ 289,070

ENCUMBEREDEncumbered means any mortgage, deed of trust, lien, charge, pledge, security interest, security agreement or other encumbrance of any kind.FUNDS FROM OPERATIONS (“FFO”) AND CORE FFOFFO, as defined by 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 non-core items, which is referred to as “Core FFO,” to be useful supplemental operating performance measures 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 to pay dividends. By excluding gains or losses related to sales of depreciated operating properties and excluding real estate depreciation (which can vary among owners of identical assets in similar condition based on historical cost accounting and useful life estimates), FFO can help investors compare the operating performance of a real estate company between periods or as compared to different companies. By further adjusting for items that are not considered part of the Company’s core business operations, Core FFO allows investors to compare the core operating performance of the Company to its performance in prior reporting periods and to the operating performance of other real estate companies without the effect of items that by their nature are not comparable from period to period and tend to obscure the Company’s actual operating results.FFO and Core FFO do not represent net income or cash flows from operations as defined by U.S. GAAP and are not intended to indicate whether cash flows will be sufficient to fund cash needs. These measures should not be considered as alternatives 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 stockholders. FFO and Core FFO also 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 2019 in the section titled "Consolidated Funds From Operations".INTEREST EXPENSE, NETInterest expense, net is presented on page S-1 of the earnings supplement for the second quarter of 2019 in the section titled "Consolidated Operating Results".

NET INDEBTEDNESS DIVIDED BY ADJUSTED EBITDAreThis credit ratio is presented on page S-6 of the earnings supplement for the second quarter of 2019 in the section titled "Selected Credit Ratios." This credit ratio is calculated by dividing net indebtedness by Adjusted EBITDAre, 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 EBITDAre is set forth in "Adjusted EBITDAre Reconciliation" on page S-17.1 of the earnings supplement for the second quarter of 2019. The calculation of this credit ratio and a reconciliation of net indebtedness to total debt at pro rata share for co-investments, net is presented in the table below (Dollars in thousands): Based on the amount for the most recent quarter, multiplied by four.Adjustments made for properties in lease-up, acquired, or disposed of during the most recent quarter and other partial quarter activity, multiplied by four. * RECONCILIATIONS OF NON-GAAP FINANCIAL MEASURES AND OTHER TERMS Total consolidated debt, net $ 5,841,251 Total debt from co-investments at pro rata share 787,452 Adjustments: Consolidated unamortized premiums, discounts, and debt issuance costs 21,847 Pro rata co-investments unamortized premiums, discounts, and debt issuance costs 3,651 Consolidated cash and cash equivalents-unrestricted (38,168) Pro rata co-investment cash and cash equivalents-unrestricted (25,760) Marketable securities (215,434) Net Indebtedness $ 6,374,839 Adjusted EBITDAre, annualized (1) $ 1,156,280 Other EBITDAre normalization adjustments, net, annualized (2) (927) Adjusted EBITDAre, normalized and annualized $ 1,155,353 Net Indebtedness Divided by Adjusted EBITDAre, normalized and annualized 5.5

NET OPERATING INCOME (“NOI”) AND SAME-PROPERTY NOI RECONCILIATIONSNOI and same-property NOI are considered by management to be important supplemental performance measures to earnings from operations included in the Company’s condensed 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 revenues 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 FINANCIAL MEASURES AND OTHER TERMS Three Months Ended Three Months Ended Six Months Ended Six Months Ended June 30, June 30, June 30, June 30, 2019 2018 2019 2018 Earnings from operations $ 124,560 $ 138,516 $ 240,255 $ 249,063 Adjustments: Corporate-level property management expenses 8,212 7,782 16,365 15,552 Depreciation and amortization 119,465 119,330 240,033 238,435 Management and other fees from affiliates (2,260) (2,197) (4,595) (4,505) General and administrative 13,927 11,125 27,386 25,938 Expensed acquisition and investment related costs 24 68 56 125 Gain on sale of real estate and land - (22,244) - (22,244) NOI 263,928 252,380 519,500 502,364 Less: Non-same property NOI (15,959) (14,224) (28,697) (27,886) Same-Property NOI $ 247,969 $ 238,156 $ 490,803 $ 474,478

PUBLIC BOND COVENANTSPublic Bond Covenants refer 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, the Company 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 Financings" in the Company's annual report on Form 10-K and other reports filed by the Company with the Securities and Exchange Commission ("SEC").The ratios set forth on page S-6 of the earnings supplement for the second quarter of 2019 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 August 7, 2019, filed by the Company as Exhibit 4.1 to the Company's Form 8-K, filed on August 7, 2019. 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 Company's total amount of Secured Debt is set forth on page S-5 of the earnings supplement for the second quarter of 2019. * RECONCILIATIONS OF NON-GAAP FINANCIAL MEASURES 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 2019 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, 2019, annualized, is calculated by dividing Unencumbered NOI, annualized for the three months ended June 30, 2019 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 Reconciliations" above. 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): (1) This table is based on the amounts for the most recent quarter, multiplied by four.(2) Includes intercompany eliminations pertaining to self-insurance and other expenses. * RECONCILIATIONS OF NON-GAAP FINANCIAL MEASURES AND OTHER TERMS Annualized Q2'19 (1) NOI $ 1,055,712 Adjustments: NOI from real estate assets sold - Other, net (2) (11,169) Adjusted Total NOI 1,044,543 Less: Encumbered NOI (209,467) Unencumbered NOI $ 835,076 Encumbered NOI $ 209,467 Unencumbered NOI 835,076 Adjusted Total NOI $ 1,044,543 Unencumbered NOI to Adjusted Total NOI 80%
