1. Basis of Presentation

Sun Communities, Inc., a Maryland corporation, and all wholly-owned or majority-owned and controlled subsidiaries, including Sun Communities Operating Limited Partnership (the "Operating Partnership"), Sun Home Services, Inc. ("SHS"), Safe Harbor Marinas, LLC ("Safe Harbor") and Tiger Topco 1 Limited (together with its subsidiaries, "Park Holidays") are referred to herein as the "Company," "SUI," "us," "we," and "our."

We follow accounting standards set by the Financial Accounting Standards Board ("FASB"). FASB establishes accounting principles generally accepted in the United States of America ("GAAP"), which we follow to ensure that we consistently report our financial condition, results of operations and cash flows. References to GAAP issued by the FASB in these footnotes are to the FASB Accounting Standards Codification ("ASC"). These unaudited Consolidated Financial Statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC") for interim financial information and in accordance with GAAP. We present interim disclosures and certain information and footnote disclosures as required by SEC rules and regulations. Accordingly, the unaudited Consolidated Financial Statements do not include all of the information and footnotes required by GAAP for complete financial statements. The accompanying unaudited Consolidated Financial Statements reflect, in the opinion of management, all adjustments, including adjustments of a normal and recurring nature, necessary for a fair presentation of the interim financial statements. All intercompany transactions have been eliminated in consolidation.

Certain prior period amounts have been revised to conform with current presentation, with no effect on net income. These include reclassification of certain revenues and expenses between Real property and Service, retail, dining and entertainment within our Marina Portfolio. There was no impact to prior period net income, shareholders equity or cash flows for any of the reclassifications. Further, the reclassification had no impact on previously reported total marina Net Operating Income ("NOI").

The results of operations for interim periods are not necessarily indicative of results that may be expected for any other interim period or for the full year. These unaudited Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2021 as filed with the SEC on February 22, 2022 (our "2021 Annual Report"). These statements have been prepared on a basis that is substantially consistent with the accounting principles applied in our 2021 Annual Report.

Our three reportable segments are: (i) Manufactured home ("MH") communities, (ii) Recreational vehicle ("RV") resorts and (iii) Marina.

7. Consolidated Variable Interest Entities

The Operating Partnership

We consolidate the Operating Partnership under the guidance set forth in ASC 810, "Consolidation." We evaluated whether the Operating Partnership met the criteria for classification as a variable interest entity ("VIE") or, alternatively, as a voting interest entity and concluded that the Operating Partnership met the criteria of a VIE. Our significant asset is our investment in the Operating Partnership, and consequently, substantially all of our assets and liabilities represent those assets and liabilities of the Operating Partnership. We are the sole general partner and generally have the power to manage and have complete control over the Operating Partnership and the obligation to absorb its losses or the right to receive its benefits.

Other Consolidated VIEs

We consolidate Sun NG RV Resorts LLC ("Sun NG Resorts"); Sun NG Whitewater RV Resorts LLC; FPG Sun Menifee 80 LLC, SHM South Fork JV, LLC; Sun Solar Energy Project LLC, Sun Solar Energy Project CA II, and FPG Sun Moreno Valley 66 LLC under the guidance set forth in ASC Topic 810, "Consolidation." We concluded that each entity is a VIE where we are the primary beneficiary, as we have the power to direct the significant activities of and absorb the significant losses and receive the significant benefits from each entity. Refer to Note 8, "Debt and Line of Credit," for additional information on Sun NG Resorts.

During the three months ended June 30, 2022, we acquired the noncontrolling equity interest held by third parties in Rudgate Village SPE LLC, Rudgate Clinton SPE LLC and Rudgate Clinton Estates, LLC (collectively, "Rudgate"), an MH community, which resulted in the Company owning a 100 percent ownership interest in Rudgate. We concluded that Rudgate was no longer a VIE. Refer to Note 9, "Equity and Temporary Equity," for additional information.

The following table summarizes the assets and liabilities of our consolidated VIEs, with the exception of the Operating Partnership, included in our Consolidated Balance Sheets after eliminations (in millions):

	June 30, 2022		December 31, 2021

Total assets related to the consolidated VIEs, with the exception of the Operating Partnership, comprised 4.4 percent and 4.9 percent of our consolidated total assets at June 30, 2022 and December 31, 2021, respectively. Total liabilities comprised 1.4 percent and 2.8 percent of our consolidated total liabilities at June 30, 2022 and December 31, 2021, respectively. Equity Interests and Noncontrolling interests related to the consolidated VIEs, on an absolute basis, comprised less than 1.0 percent of our consolidated total equity at June 30, 2022 and December 31, 2021, respectively.

In April 2022, the Operating Partnership issued $600.0 million of senior unsecured notes with an interest rate of 4.2 percent and a 10-year term, due April 15, 2032 (the "2032 Notes"). Interest on the 2032 Notes is payable semi-annually in arrears on April 15 and October 15 of each year, beginning on October 15, 2022. The net proceeds from the offering were $592.3 million after deducting underwriters' discounts and estimated offering expenses. We used the net proceeds from the offering to repay borrowings outstanding under our Senior Credit Facility (as defined below).

In October 2021, the Operating Partnership issued $450.0 million of senior unsecured notes with an interest rate of 2.3 percent and a seven-year term, due November 1, 2028 (the "2028 Notes"). Interest on the 2028 Notes is payable semi-annually in arrears on May 1 and November 1 of each year, beginning on May 1, 2022. The Operating Partnership also issued an additional $150.0 million of its 2031 Notes (as defined below).

(Unaudited)

The total outstanding principal balance of senior unsecured notes was $1.8 billion at June 30, 2022. This balance is recorded in the Unsecured debt line item on the Consolidated Balance Sheets.

Line of Credit

In April 2022, in connection with the closing of the Park Holidays acquisition, the Operating Partnership as borrower, and SUI, as guarantor, and certain lenders entered into Amendment No. 1 to the Fourth Amended and Restated Credit Agreement and Other Loan Documents (the "Credit Facility Amendment"), which amended our senior credit facility (the "Senior Credit Facility").

The Credit Facility Amendment increased the aggregate amount of our Senior Credit Facility to $4.2 billion with the ability to upsize the total borrowings by an additional $800.0 million, subject to certain conditions. The increased aggregate amount under the Senior Credit Facility consists of the following: (a) a revolving loan in an amount up to $3.05 billion and (b) a term loan facility of $1.15 billion, with the ability to draw funds from the combined facilities in U.S. dollars, Pounds sterling, Euros, Canadian dollars and Australian dollars, subject to certain limitations. The Credit Facility Amendment extended the maturity date of the revolving loan facility to April 7, 2026. At our option that maturity date may be extended two additional six-month periods. In addition, the Credit Facility Amendment established the maturity date of the term loan facility under the Credit Facility Amendment as April 7, 2025, which may not be further extended.

Prior to the Credit Facility Amendment, the Senior Credit Facility permitted aggregate borrowings of up to $2.0 billion, with an accordion feature that allowed for additional commitments of up to $1.0 billion, subject to the satisfaction of certain conditions. Prior to the amendment, $500.0 million of available borrowings under the Senior Credit Facility were scheduled to mature on October 11, 2024, with the remainder scheduled to mature on June 14, 2025. During the three months ended June 30, 2022 and 2021, we recognized losses on extinguishment of debt in our Consolidated Statements of Operations of $0.1 million related to the amendment of the Senior Credit Facility, and $0.2 million and $7.9 million, related to the termination of our $750.0 million credit facility and the $1.8 billion credit facility between Safe Harbor and certain lenders, respectively.

The Senior Credit Facility bears interest at a floating rate based on Adjusted Term Secured Overnight Financing Rate ("SOFR"), the Adjusted Eurocurrency Rate, the Daily Risk Free Rate ("RFR"), the Australian Bank Bill Swap Bid Rate ("BBSY"), the Daily Sterling Overnight Index Average ("SONIA") Rate or the Canadian Dollar Offered Rate, as applicable, plus, in all cases, a margin, which can range from 0.725 percent to 1.6 percent, subject to certain adjustments. As of June 30, 2022, the margins based on our credit ratings were 0.85 percent on the revolving loan facility and 0.95 percent on the term loan facility.

At the lenders' option, the Senior Credit Facility will become immediately due and payable upon an event of default under the Credit Facility Amendment. We had $662.0 million of borrowings outstanding under the revolving loan and $1.1 billion of borrowings outstanding under the term loan on the Senior Credit Facility as of June 30, 2022. We had $1.0 billion of revolving borrowings on our prior Senior Credit Facility as of December 31, 2021. These balances are recorded in Unsecured debt on the Consolidated Balance Sheets.

The Senior Credit Facility provides us with the ability to issue letters of credit. Our issuance of letters of credit does not increase our borrowings outstanding under the Senior Credit Facility, but does reduce the borrowing amount available. We had $2.8 million and $2.2 million of outstanding letters of credit at June 30, 2022 and December 31, 2021, respectively.

Bridge Loan Termination

In March 2022, we terminated our commitment letter with Citigroup Global Markets, Inc. ("Citigroup"), pursuant to which Citigroup (on behalf of its affiliates) previously committed to lend us up to £950.0 million, or approximately $1.2 billion converted at the March 31, 2022 exchange rate (the "Bridge Loan"). As of the date of termination, we did not have any borrowings outstanding under the Bridge Loan. During the three months ended March 31, 2022, we recognized a Loss on extinguishment of debt in our Consolidated Statement of Operations of $0.3 million related to the termination of the Bridge Loan.

Unsecured Term Loan

In October 2019, we assumed a $58.0 million secured term loan facility related to an acquisition. The term loan has a four-year term ending October 29, 2023, and bears interest at a floating rate based on the Eurodollar rate or Prime rate plus a margin ranging from 1.20 percent to 2.05 percent. Effective July 1, 2021, the agreement was amended to release the associated collateral. The amendment extended the term loan facility maturity date to October 29, 2025 and adjusted the interest rate margin to a range from 0.8 percent to 1.6 percent. As of June 30, 2022, the margin was 0.95 percent. The outstanding balance was $24.6 million at June 30, 2022 and $31.6 million at December 31, 2021. These balances are recorded in Unsecured debt and Secured debt on the Consolidated Balance Sheets, respectively.

Preferred Equity - Sun NG Resorts - Mandatorily Redeemable

In connection with the investment in Sun NG Resorts in June 2018, $35.3 million of mandatorily redeemable Preferred Equity ("Preferred Equity - Sun NG Resorts") was purchased by unrelated third parties. The Preferred Equity - Sun NG Resorts carries a preferred rate of return of 6.0 percent per annum. The Preferred Equity - Sun NG Resorts has a seven-year term ending June 1, 2025 and can be redeemed in the fourth quarter of 2024 at the holders' option. The Preferred Equity - Sun NG Resorts as of June 30, 2022 was $35.2 million. This balance is recorded within the Unsecured debt line item on the Consolidated Balance Sheets. Refer to Note 7, "Consolidated Variable Interest Entities," for additional information.

Preferred OP Units - Mandatorily Redeemable

Preferred OP units at June 30, 2022 and December 31, 2021 include $34.7 million of Aspen preferred OP units issued by the Operating Partnership. As of June 30, 2022, these units are convertible indirectly into 402,003 shares of our common stock.

In January 2020, we amended the Operating Partnership's partnership agreement. The amendment extended the automatic redemption date and reduced the annual distribution rate for 270,000 of the Aspen preferred OP units (the "Extended Units"). Subject to certain limitations, at any time prior to January 1, 2024 (or prior to January 1, 2034 with respect to the Extended Units), the holder of each Aspen preferred OP unit at its option may convert such Aspen preferred OP unit into: (a) if the average closing price of our common stock for the preceding ten trading days is $68.00 per share or less, 0.397 common OP units; or (b) if the ten-day average closing price is greater than $68.00 per share, the number of common OP units is determined by dividing (i) the sum of (A) $27.00 plus (B) 25.0 percent of the amount by which the ten-day average closing price exceeds $68.00 per share, by (ii) the ten-day average closing price. The current preferred distribution rate is 3.8 percent on the Extended Units and 6.5 percent on all other Aspen preferred OP units. On January 2, 2024 (or January 2, 2034 with respect to the Extended Units), we are required to redeem for cash all Aspen preferred OP units that have not been converted to common OP units. As of June 30, 2022, 270,000 of the Extended Units and 1,013,819 other Aspen preferred units were outstanding. These balances are recorded within the Unsecured debt line item on the Consolidated Balance Sheets.

Covenants

The mortgage term loans, senior unsecured notes and Senior Credit Facility are subject to various financial and other covenants. The most restrictive covenants are pursuant to (a) the terms of the Senior Credit Facility, which contains a minimum fixed charge coverage ratio, maximum leverage ratio, distribution ratio and variable rate indebtedness, and (b) the terms of the senior unsecured notes, which contain a total debt to total assets ratio, secured debt to total assets ratio, consolidated income available for debt service to debt service ratio and unencumbered total asset value to unsecured debt covenants ratio.

9. Equity and Temporary Equity

Temporary Equity

Redeemable Preferred OP Units

Temporary equity includes preferred securities that are redeemable for cash at the holder's option or upon the occurrence of an event that is not solely within our control based on a fixed or determinable price. These securities are not mandatorily redeemable for cash nor do they contain a fixed maturity date. The following table sets forth the various series of redeemable preferred OP units that were outstanding as of June 30, 2022 and the related terms, and summarizes the balance included on our Consolidated Balance Sheets (in millions, except for statistical information):

Equity Interest - NG Sun LLC - In June 2018, in connection with the investment in Sun NG Resorts, unrelated third parties purchased $6.5 million of Series B preferred equity interests and $15.4 million of common equity interests in Sun NG Resorts (herein jointly referred to as "Equity Interest - NG Sun LLC"). In April and September 2020, in connection with certain acquisitions, $3.0 million of Series B preferred equity interests were converted to common equity interests. The Series B preferred equity interests carry a preferred return at a rate that, at any time, is equal to the interest rate on Sun NG Resorts' indebtedness at such time. The current rate of return is 5.0 percent. The Equity Interest - NG Sun LLC does not have a fixed maturity date and can be redeemed in the fourth quarters of 2024, 2025 or 2026 at the holders' option. Sun NG LLC, our subsidiary, has the right during certain periods each year, with or without cause, or for cause at any time, to elect to buy NG Sun LLC's interest. During a limited period in 2024, NG Sun LLC has the right to put its interest to Sun NG LLC. If either party exercises its option, the property management agreement will be terminated, and we are required to purchase the remaining interests of NG Sun LLC and the property management agreement at fair value. In December 2021, the operating agreement was amended and we paid Sun NG Resorts a contingent consideration earnout in the amount of $38.3 million. The contingent consideration payment was recognized as an additional purchase price payment within Land improvements and buildings in the Consolidated Balance Sheets, and within Acquisition of properties, net of cash acquired in the Consolidated Statement of Cash Flows. The Equity Interest - NG Sun LLC balance was $28.9 million and $24.7 million as of June 30, 2022 and December 31, 2021, respectively. Refer to Note 7, "Consolidated Variable Interest Entities," and Note 8, "Debt and Line of Credit," for additional information.

Permanent Equity

Universal Shelf Registration Statement

In April 2021, we filed a new universal shelf registration statement on Form S-3 with the SEC. The shelf registration statement was deemed automatically effective and provides for the registration of unspecified amounts of equity and debt securities. We have the authority to issue 200,000,000 shares of capital stock, of which 180,000,000 shares are common stock and 20,000,000 are shares of preferred stock, par value $0.01 per share. As of June 30, 2022, we had 121,644,228 shares of common stock issued and outstanding and no shares of preferred stock were issued and outstanding.

Public Equity Offerings

In November 2021, we entered into two forward sale agreements relating to an underwritten registered public offering of 4,025,000 shares of our common stock at a public offering price of $185.00 per share and completed the offering on November 18, 2021 (the "November 2021 Forward Sale Agreements"). We did not initially receive any proceeds from the sale of shares of our common stock by the forward purchaser or its affiliates. On April 15, 2022, we completed the physical settlement of the 4,025,000 shares of common stock and received aggregate net proceeds of $705.4 million. We used the net proceeds to repay borrowings outstanding under our Senior Credit Facility, and for working capital and general corporate purposes.

At the Market Offering Sales Agreement

In December 2021, we entered into an At the Market Offering Sales Agreement with certain sales agents and forward sellers pursuant to which we may sell, from time to time, up to an aggregate gross sales price of $1.25 billion of our common stock (the "Sales Agreement"), through the sales agents, acting as our sales agents or, if applicable, as forward sellers, or directly to the sales agents as principals for their own accounts. The sales agents and forward sellers are entitled to compensation in an agreed amount not to exceed 2.0 percent of the gross price per share for any shares sold under the Sales Agreement. We simultaneously terminated our prior sales agreement upon entering into the Sales Agreement.

During the three months ended March 31 and June 30, 2022, we entered into forward sales agreements with respect to 600,503 shares of common stock for $107.9 million, and 290,600 shares of common stock for $50.1 million, respectively, under our at the market offering program. These forward sale agreements were not settled as of June 30, 2022, but we expect to settle them by the end of March and June 2023, respectively.

During the year ended December 31, 2021, we entered into forward sale agreements with respect to 1,820,109 shares of common stock under our prior at the market offering program for $356.5 million. During the three months ended June 30, 2022, we completed the physical settlement of 1,200,000 shares of common stock and received net proceeds of $229.5 million. We expect to settle the remaining 620,109 shares of common stock by the end of September 2022.

Refer to Note 19, "Subsequent Events," for information regarding the settlement of certain forward sale agreements outstanding under our at the market offering program after June 30, 2022.

Issuances of Common Stock and OP Units in Connection with the Acquisition of Certain Properties

Issuance of Common Stock

On April 8, 2022, we issued an aggregate of 186,044 shares of our common stock in connection with the acquisition of Park Holidays.

Issuances of Common OP Units

Six Months Ended June 30, 2022 and 2021	Common OP Units Issued		Related Acquisition
May 2022	10,854	(1)	Rudgate
May 2022	5,605		Kittery Point
February 2022	14,683		Jarrett Bay Boatworks

(1) During the three months ended June 30, 2022, we acquired the noncontrolling equity interest held by third parties in Rudgate for a total purchase price of $3.1 million. As consideration, we issued 10,854 common OP units and paid the remainder of the purchase price in cash. The acquisition resulted in the Company owning a 100 percent controlling interest in Rudgate. The acquisition was accounted for as an equity transaction in accordance with ASC Topic 810, "Consolidation," with the difference between the purchase price and the acquired noncontrolling interest of $13.2 million recorded as an increase to Additional Paid-in Capital on the Consolidated Balance Sheets. Refer to Note 7, "Consolidated Variable Interest Entities," for additional information.

Issuances of Preferred OP Units

Issuance of Series E Preferred OP Units - In January 2020, we issued 90,000 Series E preferred OP units in connection with the acquisition of Sun Outdoors Cape Cod. The Series E preferred OP units have a stated issuance price of $100.00 per OP unit and carry a preferred return of 5.25 percent until the second anniversary of the issuance date. Commencing with the second anniversary of the issuance date, the Series E preferred OP units carry a preferred return of 5.5 percent. Commencing with the first anniversary of the issuance date, subject to certain limitations, each Series E preferred OP unit can be exchanged for our common stock equal to the quotient obtained by dividing $100.00 by $145.00 (as such ratio is subject to adjustments for certain capital events). As of June 30, 2022, 85,000 Series E preferred OP units were outstanding.

10. Share-Based Compensation

As of June 30, 2022, we had two share-based compensation plans: the Sun Communities, Inc. 2015 Equity Incentive Plan (as amended, the "2015 Equity Incentive Plan") and the First Amended and Restated 2004 Non-Employee Director Option Plan (as amended, the "2004 Non-Employee Director Option Plan"). We believe granting equity awards will provide certain executives, key employees and directors additional incentives to promote our financial success and promote employee and director retention by providing an opportunity to acquire or increase the direct proprietary interest of those individuals in our operations and future. Time based awards for directors generally vest over three years. Time based awards for key employees and executives generally vest over five years. Market condition awards for the executives generally vest after three years.

First Amendment to the 2015 Equity Incentive Plan

At our 2022 Annual Meeting on May 17, 2022, our shareholders approved the First Amendment to the 2015 Equity Incentive Plan. The First Amendment increased the number of shares of common stock that may be issued under the 2015 Equity Incentive Plan to 4,750,000. As of June 30, 2022, there were 3,130,389 shares available for future issuance.

United Kingdom Sub-Plan

On April 6, 2022, the Board of Directors adopted the UK Sub-Plan under the 2015 Equity Incentive Plan, which is solely applicable to employee participants located in the UK, and establishes certain rules and limitations for participation in the 2015 Equity Incentive Plan by UK employees for the purpose of complying with applicable UK laws.

During the six months ended June 30, 2022 and 2021, shares were granted as follows:

11. Segment Reporting

ASC Topic 280, "Segment Reporting," establishes standards for the way the business enterprises report information about operating segments in its financial statements. As described in Note 1, "Basis of Presentation," we analyze our operating results through the following segments: (i) Manufactured home ("MH") communities, (ii) Recreational vehicle ("RV") resorts and (iii) Marina.

The MH segment owns, operates, develops, or has an interest in, a portfolio of MH communities throughout the U.S. and a portfolio of holiday parks throughout the UK, and is in the business of acquiring, operating and developing ground-up MH communities to provide affordable housing solutions to residents. The MH segment also provides manufactured home sales and leasing services to tenants and prospective tenants of our communities.

The RV segment owns, operates, develops, or has an interest in, a portfolio of RV resorts and is in the business of acquiring, operating and developing ground up RV resorts throughout the U.S. and in Canada. It also provides leasing services for vacation rentals within the RV resorts.

Properties containing both MH and RV sites are classified to a segment based on the predominant site counts at the properties.

The Marina segment owns, operates, and develops marinas, and is in the business of acquiring and operating marinas throughout the U.S., with the majority of such marinas concentrated in coastal regions, and others located in various inland regions and Puerto Rico.

12. Income Taxes

We have elected to be taxed as a real estate investment trust ("REIT") pursuant to Section 856(c) of the Internal Revenue Code of 1986, as amended ("Code"). In order for us to qualify as a REIT, at least 95 percent of our gross income in any year must be derived from qualifying sources. In addition, a REIT must distribute annually at least 90 percent of its REIT taxable income (calculated without any deduction for dividends paid and excluding capital gain) to its shareholders and meet other tests.

Qualification as a REIT involves the satisfaction of numerous requirements (on an annual and quarterly basis) established under highly technical and complex Code provisions for which there are limited judicial or administrative interpretations and involves the determination of various factual matters and circumstances not entirely within our control. In addition, frequent changes occur in the area of REIT taxation, which requires us to continually monitor our tax status. We analyzed the various REIT tests and confirmed that we continued to qualify as a REIT for the six months ended June 30, 2022.

As a REIT, we generally will not be subject to United States ("U.S.") federal income taxes at the corporate level on the ordinary taxable income we distribute to our shareholders as dividends. If we fail to qualify as a REIT in any taxable year, our taxable income could be subject to U.S. federal income tax at regular corporate rates. Even if we qualify as a REIT, we may be subject to certain state and local income taxes, as well as U.S. federal income and excise taxes on our undistributed income. In addition, taxable income from non-REIT activities managed through taxable REIT subsidiaries is subject to federal, state and local income taxes. We are also subject to local income taxes in Canada, Puerto Rico and the United Kingdom due to certain properties located in those jurisdictions. We do not provide for withholding taxes on our undistributed earnings from our Canadian subsidiaries as they are reinvested and will continue to be reinvested indefinitely outside of the U.S. However, we are subject to Australian withholding taxes on distributions from our investment in Ingenia Communities Group. As currently structured, we are not subject to UK withholding taxes on distributions from our United Kingdom properties.

Deferred tax assets and liabilities reflect the impact of temporary differences between the amounts of assets and liabilities for financial reporting purposes and the basis of such assets and liabilities as measured by tax laws. Deferred tax assets are reduced, if necessary, by a valuation allowance to the amount where realization is more likely than not assured after considering all available evidence. Our temporary differences primarily relate to net operating loss carryforwards, depreciation and basis differences between tax and GAAP. Our deferred tax assets that have a full valuation allowance relate to our taxable REIT subsidiaries. As of June 30, 2022, we had $237.0 million of net deferred tax liabilities, comprised of deferred tax assets, net of valuation allowance, of $2.9 million, and deferred tax liabilities of $239.9 million. The deferred tax liability balance is comprised primarily of basis differences in our foreign investment in properties in the United Kingdom and Canada. As of December 31, 2021, we had $20.7 million of net deferred tax liabilities, comprised of deferred tax assets, net of valuation allowance, of $3.0 million, and deferred tax liabilities of $23.7 million. These balances include a net deferred tax asset, net of valuation allowance, in the United States of $1.2 million as of June 30, 2022 and December 31, 2021. The net deferred tax assets and deferred tax liabilities are recorded within Other Assets and Other Liabilities, respectively, on our Consolidated Balance Sheets as of June 30, 2022 and December 31, 2021.

We had no unrecognized tax benefits as of June 30, 2022 and during 2021. We do not expect significant changes in tax positions that would result in unrecognized tax benefits within one year of June 30, 2022.

For the three and six months ended June 30, 2022, we recorded current tax expense for federal, state, Canadian, Puerto Rican, UK income taxes and Australian withholding taxes totaling $3.9 million and $5.2 million, respectively. For the three and six months ended June 30, 2021, we recorded current tax expense for federal, state, Canadian income taxes and Australian withholding taxes totaling $1.2 million and $1.0 million, respectively.

For the three and six months ended June 30, 2022, we recorded a deferred tax benefit of $0.3 million, respectively. For the six months ended June 30, 2021, we recorded deferred tax benefit of $0.1 million, respectively.

13. Earnings Per Share

Earnings per share ("EPS") is computed by dividing net income by the weighted average number of common shares outstanding during the period on a basic and diluted basis. We calculate diluted EPS using the more dilutive of the treasury stock method and the two-class method for stock option and restricted common shares, the treasury stock method for forward equity sales and the if converted method for convertible units.

From time to time, we enter into forward equity sales agreements, which are discussed in Note 9, "Equity and Temporary Equity." We considered the potential dilution resulting from the forward equity sales agreements on the EPS calculations. At inception, the agreements do not have an effect on the computation of basic EPS as no shares are delivered unless there is a physical settlement. Common shares issued upon the physical settlement of the forward equity sales agreements, weighted for the period these common shares are outstanding, are included in the denominator of basic EPS. To determine the dilution resulting from the forward equity sales agreements during the period of time prior to settlement, we calculate the number of weighted-average shares outstanding - diluted.

Our potentially dilutive securities include our potential common shares related to our forward equity offerings, our unvested restricted common shares, and our Operating Partnership outstanding common OP units, Series A-1 preferred OP units, Series A-3 preferred OP units, Series C preferred OP units, Series D preferred OP units, Series E preferred OP units, Series F preferred OP units, Series G preferred OP units, Series H preferred OP units, Series I preferred OP units, Series J preferred OP units and Aspen preferred OP Units, which, if converted or exercised, may impact dilution.

Diluted EPS considers the impact of potentially dilutive securities except when the potential common shares have an anti-dilutive effect. Our unvested restricted stock common shares contain rights to receive non-forfeitable distributions and participate equally with common stock with respect to distributions issued or declared, and thus, are participating securities, requiring the two-class method of computing EPS. In calculating the two-class method, undistributed earnings are allocated to both common shares and participating securities based on the weighted average number of shares outstanding during the period. The two-class method determines EPS by (1) dividing the sum of distributed earnings allocated to common shareholders and undistributed earnings allocated to common shareholders by the weighted average number of shares of common stock outstanding for the period; and (2) dividing the sum of distributed earnings allocated to participating securities and undistributed earnings allocated to participating securities by the weighted average number of shares of participating securities for the period. The remaining potentially dilutive common shares do not contain rights to distributions and are included in the computation of diluted EPS.

14. Derivative Financial Instruments

Our objective and strategy in using interest rate derivatives is to manage exposure to interest rate movements, thereby minimizing the effect of interest rate changes and the effect they could have on future cash outflows (forecasted interest payments) on a forecasted issuance of long-term debt. Treasury locks are used to accomplish this objective. We do not enter into derivative instruments for speculative purposes.

We designated the treasury lock contracts as cash flow hedges under ASC Topic 815, "Derivatives and Hedging." The risk being hedged is the interest rate risk related to forecasted transactions and the benchmark interest rate used is the on-the-run 10-year U.S. Treasury rate.

During the three months ended June 30, 2022, in connection with the 2032 Notes issuance, we settled four 10-year Treasury rate lock contracts totaling $600.0 million and received a settlement payment of $35.3 million (the "Treasury Lock Settlement"). As of June 30, 2022, the net accumulated gain is included in Accumulated other comprehensive income in our Consolidated Balance Sheets, and is being amortized as a reduction to interest expense on a straight-line basis over the 10-year term of the hedged transaction. We estimate that $3.5 million will be reclassified as a reduction to interest expense over the next 12 months. Following the Treasury Lock Settlement, we had no treasury lock contracts outstanding as of June 30, 2022. Refer to Note 19, "Subsequent Events," for information regarding interest rate derivative activity subsequent to June 30, 2022.

15. Fair Value of Financial Instruments

Our financial instruments consist primarily of cash, cash equivalents and restricted cash, marketable securities, notes and other receivables, derivatives assets, debt, warrants and other liabilities. We utilize fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures, pursuant to ASC 820, "Fair Value Measurements and Disclosures." The following methods and assumptions were used in order to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value:

ASC 820, "Fair Value Measurements and Disclosures," requires disclosure regarding determination of fair value for assets and liabilities and establishes a hierarchy under which these assets and liabilities must be grouped, based on significant levels of observable or unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our market assumption. This hierarchy requires the use of observable market data when available. These two types of inputs have created the following fair value hierarchy:

Level 1 - Quoted unadjusted prices for identical instruments in active markets that we have the ability to access;

Level 2 - Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-derived valuations in which all significant inputs and significant value drivers are observable (e.g. interest rates, yield curves, prepayment speeds, default rates, loss severity, etc.) in active markets or can be corroborated by observable market data; and

Level 3 - Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. The unobservable inputs reflect our assumptions about the assumptions that market participants would use.

We utilize fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The following methods and assumptions were used in order to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value:

Cash, Cash Equivalents and Restricted Cash

The carrying values of cash, cash equivalents and restricted cash approximate their fair market values due to the short-term nature of the instruments. These are classified as Level 1 in the hierarchy.

Marketable Securities

Marketable securities held by us and accounted for under ASC 321, "Investments - Equity Securities," are measured at fair value. Any change in fair value is recognized in the Consolidated Statement of Operations in the Gain / (loss) on remeasurement of marketable securities in accordance with ASU 2016-01, "Financial Instruments - Overall (Subtopic 825-10): Recognition and measurement of financial assets and financial liabilities." The fair value is measured by the quoted unadjusted share price which is readily available in active markets (Level 1).

The change in the marketable securities balance is as follows (in millions):

	Six Months Ended		Year Ended
	June 30, 2022		December 31, 2021
Beginning Balance	$	186.9	$	124.7
Additional purchases	—		35.5

Foreign currency translation adjustment	(7.0)		(9.2)
Dividend reinvestment, net of tax	1.5		2.5
Ending Balance	$	114.6	$	186.9

Installment Notes Receivable on Manufactured Homes

Installment notes receivable on manufactured homes are recorded at fair value and are measured using model-derived indicative pricing using primarily unobservable inputs, inclusive of default rates, interest rates and recovery rates (Level 3). Refer to Note 4, "Notes and Other Receivables," for additional information.

Notes Receivable from Real Estate Developers and Operators

Notes receivable from real estate developers and operators are recorded at fair value and are measured using model-derived indicative pricing using primarily unobservable inputs including interest rates and counterparty performance (Level 3). The carrying values of the notes generally approximate their fair market values either due to the nature of the note and / or the note being secured by underlying collateral and / or personal guarantees. Refer to Note 4, "Notes and Other Receivables," for additional information.

Derivative Assets - Interest Rate Derivatives

Interest rate derivatives are recorded at fair value and consist of Treasury locks. The fair value of the Treasury lock is measured using observable inputs based on the 10-year Treasury note rate (Level 2).

Secured Debt

Secured debt consists primarily of our mortgage term loans. The fair value of mortgage term loans is based on the estimates of management and on rates currently quoted, rates currently prevailing for comparable loans and instruments of comparable maturities (Level 2). Refer to Note 8, "Debt and Line of Credit," for additional information.

Unsecured Debt

Senior unsecured notes - the fair value of senior unsecured notes is based on the estimates of management and on rates currently quoted, rates currently prevailing for comparable loans and instruments of comparable maturities (Level 2). Refer to Note 8, "Debt and Line of Credit," for additional information.

Line of credit and other unsecured debt - consists primarily of our Senior Credit Facility. We have variable rates on our Senior Credit Facility. The fair value of the debt with variable rates approximates carrying value as the interest rates of these amounts approximate market rates. The estimated fair value of our indebtedness as of June 30, 2022 approximated its gross carrying value.

Other Financial Liabilities

We estimate the fair value of contingent consideration liabilities based on valuation models using significant unobservable inputs that generally consider discounting of future cash flows using market interest rates and adjusting for non-performance risk over the remaining term of the liability (Level 3).

Level 3 Reconciliation, Measurements and Transfers

We review the fair value hierarchy classifications each reporting period. Changes in the observability of the valuation attributes may result in a reclassification of certain financial assets or liabilities. Such reclassifications are reported as transfers in and out of Level 3 at the beginning fair value for the reporting period in which the changes occur. Availability of secondary market activity and consistency of pricing from third-party sources impacts our ability to classify securities as Level 2 or Level 3. There were no transfers into or out of Level 3 during the six months ended June 30, 2022.

The following table summarizes changes to our financial instruments carried at fair value and classified within Level 3 of the fair value hierarchy for the three and six months ended June 30, 2022 and 2021 (in millions):

18. Recent Accounting Pronouncements

Recent Accounting Pronouncements - Adopted

In August 2020, the FASB issued ASU 2020-06, "Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity's Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity's Own Equity." This update simplifies the accounting for convertible instruments by eliminating the models that require separation of a cash conversion or beneficial conversion feature from the host contract. Under the amended guidance, a convertible debt instrument is treated as one liability accounted for at its amortized cost and convertible preferred stock is considered one equity instrument accounted for at its historical cost, unless (a) there are other features that require bifurcation as a derivative, or (b) convertible debt was issued at a substantial premium. This update also eliminates several triggers for derivative accounting, including a requirement to settle certain contracts by delivering registered shares. Additionally, this update provides clarifications to improve the consistency of earnings per share (EPS) calculations. We adopted the ASU on January 1, 2022. The adoption of this ASU did not have an impact on our Consolidated Financial Statements.

Recent Accounting Pronouncements - Not Yet Adopted

In March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848) - Facilitation of the Effects of Reference Rate Reform on Financial Reporting," which provides optional guidance for accounting for contracts, hedging relationships and other transactions affected by the reference rate reform, if certain criteria are met. The provisions of this standard are available for election through December 31, 2022. As of June 30, 2022, we do not expect the transition from LIBOR to alternative reference interest rates will have a material impact on our Consolidated Financial Statements as the majority of our debt has fixed interest rates.

19. Subsequent Events

Acquisitions

Subsequent to the three months ended June 30, 2022, we acquired the following properties:

Property Name	Property Type	Sites, Wet Slips and Dry Storage Spaces	Development Sites	State, Province or Country	Total Purchase Price (in millions)
Gurney's Star Island Marina & Resort(1)	Marina	230	—	NY	$	190.0
Total Subsequent Acquisitions		230	—		$	190.0

(1) As part of the closing, we deposited funds into an escrow account. As of June 30, 2022, the deposit of $192.0 million is recorded within Other Assets on the Consolidated Balance Sheets.

Development Activity

Subsequent to the three months ended June 30, 2022, we acquired two land parcels located in the United States for an aggregate purchase price of $5.7 million.

Assets Held for Sale

We periodically classify real estate assets as held for sale. An asset is classified as held-for-sale after an active program to sell an asset has commenced and when the sale is probable. In July 2022, we identified two RV resorts in California comprised of 852 sites as held for sale, with total assets of $45.6 million and total liabilities of $13.0 million.

Equity Transactions

On July 5, 2022, we settled forward sale agreements with a total of 986,909 shares of common stock under our at the market offering program. The aggregate net proceeds from the settlement of the forward sale agreements was $180.7 million. We used the net proceeds to repay borrowings outstanding under our Senior Credit Facility.

On July 14, 2022, a third party elected to convert 922,000 Series I preferred OP units and 130,475 Common OP units into an aggregate of 692,670 shares of our common stock. After the conversion date, there were no Series I preferred OP units outstanding.

Derivative Transactions

On July 1, 2022, we entered into two treasury lock contracts with an aggregate notional value of $200.0 million to hedge interest rate risk associated with the future issuance of long-term fixed rate debt. The benchmark interest rate used is the on-the-run 10-year U.S. Treasury. We have designated these treasury lock contracts as cash flow hedges under ASC Topic 815, "Derivatives and Hedging." Accordingly, the unrealized gains or losses on the treasury lock contracts will be recorded within Accumulated Other Comprehensive Income on the Consolidated Balance Sheets and will be reclassified into earnings in the same period during which the hedged transaction affects earnings.

On July 20 and July 21, 2022, we entered into interest rate swap agreements to hedge variable rate borrowings of £400.0 million under the term loan on the Senior Credit Facility. The interest rate swaps lock in a total fixed rate, inclusive of spread, of 3.67 percent through the term loan maturity date of April 7, 2025.

We have evaluated our Consolidated Financial Statements for subsequent events through the date that this Form 10-Q was issued.

ITEM 2.     MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of the consolidated financial condition and results of operations should be read in conjunction with the Consolidated Financial Statements and the accompanying Notes, along with our 2021 Annual Report.

OVERVIEW

We are a fully integrated, self-administered and self-managed REIT. As of June 30, 2022, we owned and operated or held an interest in a portfolio of 661 developed properties located in 39 states throughout the United States, Ontario, Canada, the United Kingdom and Puerto Rico, including 339 MH communities, 161 RV resorts, 31 properties containing both MH and RV sites, and 130 marinas. We have been in the business of acquiring, operating, developing and expanding MH communities and RV resorts since 1975 and marinas since 2020. We lease individual sites with utilities access for placement of manufactured homes, RVs or boats to our customers. We are also engaged in the marketing, selling and leasing of new and pre-owned homes to current and future residents in our MH communities. The Rental Program operations within our MH communities support and enhance our occupancy levels, property performance and cash flows.

SIGNIFICANT ACCOUNTING POLICIES

We have identified significant accounting policies that, as a result of the judgments, uncertainties and complexities of the underlying accounting standards and operations involved could result in material changes to our financial condition or results of operations under different conditions or using different assumptions. Details regarding significant accounting policies are described fully in our 2021 Annual Report.

NON-GAAP FINANCIAL MEASURES

In addition to the results reported in accordance with GAAP in our "Results of Operations" below, we have provided information regarding net operating income ("NOI") and funds from operations ("FFO") as supplemental performance measures. We believe NOI and FFO are appropriate measures given their wide use by and relevance to investors and analysts following the real estate industry. NOI provides a measure of rental operations and does not factor in depreciation, amortization and non-property specific expenses such as general and administrative expenses. FFO, reflecting the assumption that real estate values rise or fall with market conditions, principally adjusts for the effects of GAAP depreciation / amortization of real estate assets. In addition, NOI and FFO are commonly used in various ratios, pricing multiples / yields and returns and valuation calculations used to measure financial position, performance and value.

NOI is derived from operating revenues minus property operating expenses and real estate taxes. NOI is a non-GAAP financial measure that we believe is helpful to investors as a supplemental measure of operating performance because it is an indicator of the return on property investment and provides a method of comparing property performance over time. We use NOI as a key measure when evaluating performance and growth of particular properties and / or groups of properties. The principal limitation of NOI is that it excludes depreciation, amortization, interest expense and non-property specific expenses such as general and administrative expenses, all of which are significant costs. Therefore, NOI is a measure of the operating performance of our properties rather than of the Company overall.

We believe that GAAP net income (loss) is the most directly comparable measure to NOI. NOI should not be considered to be an alternative to GAAP net income (loss) as an indication of our financial performance or GAAP cash flow from operating activities as a measure of our liquidity; nor is it indicative of funds available for our cash needs, including our ability to make cash distributions. Because of the inclusion of items such as interest, depreciation and amortization, the use of GAAP net income (loss) as a performance measure is limited as these items may not accurately reflect the actual change in market value of a property, in the case of depreciation and in the case of interest, may not necessarily be linked to the operating performance of a real estate asset, as it is often incurred at a parent company level and not at a property level.

FFO is defined by the National Association of Real Estate Investment Trusts ("NAREIT") as GAAP net income (loss), excluding gains (or losses) from sales of depreciable operating property, plus real estate related depreciation and amortization, real estate related impairments, and after adjustments for unconsolidated partnerships and joint ventures. FFO is a non-GAAP financial measure that management believes is a useful supplemental measure of our operating performance. By excluding gains and losses related to sales of previously depreciated operating real estate assets, impairment and excluding real estate asset depreciation and amortization (which can vary among owners of identical assets in similar condition based on historical cost accounting and useful life estimates), FFO provides a performance measure that, when compared period-over-period, reflects the impact to operations from trends in occupancy rates, rental rates, and operating costs, providing perspective not readily apparent from GAAP net income (loss). Management believes the use of FFO has been beneficial in improving the understanding of operating results of REITs among the investing public and making comparisons of REIT operating results more meaningful. We also use FFO excluding certain gain and loss items that management considers unrelated to the operational and financial performance of our core business ("Core FFO"). We believe that Core FFO provides enhanced comparability for investor evaluations of period-over-period results.

We believe that GAAP net income (loss) is the most directly comparable measure to FFO. The principal limitation of FFO is that it does not replace GAAP net income (loss) as a performance measure or GAAP cash flow from operations as a liquidity measure. Because FFO excludes significant economic components of GAAP net income (loss) including depreciation and amortization, FFO should be used as a supplement to GAAP net income (loss) and not as an alternative to it. Furthermore, FFO is not intended as a measure of a REIT's ability to meet debt principal repayments and other cash requirements, nor as a measure of working capital. FFO is calculated in accordance with our interpretation of standards established by NAREIT, which may not be comparable to FFO reported by other REITs that interpret the NAREIT definition differently.

Seasonality of Revenue

The RV and Marina industries are seasonal in nature, and the results of operations in any one period may not be indicative of results in future periods.

In the RV segment, certain properties maintain higher occupancy during the summer months, while other properties maintain higher occupancy during the winter months. Based on the location of our properties with transient RV sites, our portfolio generally produces higher revenues between April and September than between October and March. Real property - transient revenue is included in RV segment revenue. As of June 30, 2022, we recognized Real property - transient revenue of $42.7 million in the first quarter and $93.1 million in the second quarter. Real property - transient revenue was $266.6 million for the year ended December 31, 2021. In 2021, Real property - transient revenue was recognized 11.9 percent in the first quarter, 27.3 percent in the second quarter, 44.9 percent in the third quarter and 15.9 percent in the fourth quarter.

In the Marina segment, demand for wet slip storage increases during the summer months as customers contract for the summer boating season, which also drives non-storage revenue streams such as service, fuel and on-premises restaurants or convenience stores. Demand for dry storage increases during the winter season as seasonal weather patterns require boat owners to store their vessels on dry docks and within covered racks. As of June 30, 2022, we recognized seasonal Real property revenue of $62.4 million in the first quarter and $79.4 million in the second quarter. Seasonal Real property revenue was $246.6 million for the year ended December 31, 2021. In 2021, Seasonal Real property revenue was recognized 17.7 percent in the first quarter, 25.0 percent in the second quarter, 29.9 percent in the third quarter and 27.4 percent in the fourth quarter.

Real Property Operations - Same Property

A key management tool used when evaluating performance and growth of our properties is a comparison of the Same Property portfolio. Same Property refers to properties that we have owned for at least the preceding year, exclusive of properties recently completed or under construction, and other properties as determined by management. The Same Property data may change from time-to-time depending on acquisitions, dispositions, management discretion, significant transactions or unique situations.

In order to evaluate the growth of the Same Property portfolio, management has classified certain items differently than our GAAP statements. The reclassification difference between our GAAP statements and our Same Property portfolio is the reclassification of utility revenues from real property revenue to operating expenses. A significant portion of our utility charges are re-billed to our residents.

For the three months ended June 30, 2022 and 2021:

•The MH segment increase in NOI of $4.3 million, or 3.1 percent, when compared to the same period in 2021 is primarily due to an increase in Real property (excluding transient) revenue of $7.5 million, or 4.3 percent, partially offset by increased property operating expenses. Real property (excluding transient) revenue increased primarily due to a 4.1 percent increase in monthly base rent.

•The RV segment increase in NOI of $3.0 million, or 4.6 percent, when compared to the same period in 2021 is primarily due to an increase in Real property (excluding transient) revenue of $5.7 million, or 12.1 percent, partially offset by increased operating expenses. The increase in Real property - (excluding transient) revenue was primarily due to a 6.8 percent increase in monthly base rent and conversions of transient RV sites to annual RV sites.

For the six months ended June 30, 2022 and 2021:

•The MH segment increase in NOI of $8.3 million, or 3.1 percent, when compared to the same period in 2021 is primarily due to an increase in Real property (excluding transient) revenue of $15.2 million, or 4.3 percent, partially offset by increased operating expenses. Real property (excluding transient) revenue increased primarily due to a 4.1 percent increase in monthly base rent.

•The RV segment increase in NOI of $12.6 million, or 11.5 percent, when compared to the same period in 2021 is primarily due to an increase in Real property (excluding transient) revenue of $12.5 million, or 13.7 percent, primarily due to an increase in monthly base rent and conversions of transient RV sites to annual RV sites.

We have reclassified utility revenues of $2.9 million for the three months ended June 30, 2022 and 2021, and $5.4 million and $5.5 million for the six months ended June 30, 2022 and 2021, respectively, to reflect the utility expenses associated with our Same Property Marina net of recovery.

Same Property results for the three and six months ended June 30, 2021, include reclassification of $8.3 million of expense, net from Real property operating expense to Service, retail, dining and entertainment expense to more precisely align certain revenues and expenses within Real property results and Service, retail, dining and entertainment results. The reclassifications had no impact on previously reported total portfolio Marina NOI. Refer to Real Property Operations – Total Portfolio above for additional information regarding these reclassifications.

For the three months ended June 30, 2022 and 2021, the $3.1 million, or 7.1 percent, increase in Marina Real Property NOI is primarily due to the $3.9 million, or 7.4 percent, increase in Real property (excluding transient) revenue, partially offset by increased property operating expenses.

For the six months ended June 30, 2022 and 2021, the $3.5 million, or 5.0 percent, increase in Marina Real Property NOI is primarily due to the $6.4 million, or 6.6 percent, increase in Real property (excluding transient) revenue, partially offset by increased property operating expenses.

LIQUIDITY AND CAPITAL RESOURCES

Short-term Liquidity

Our principal short-term liquidity demands historically have been, and are expected to continue to be, distributions to our shareholders and the unit holders of the Operating Partnership, property acquisitions, development and expansion of our properties, capital improvement of our properties, the purchase of new and pre-owned homes, and debt repayment. We intend to meet our short-term liquidity requirements through available cash balances, cash flows generated from operations, draws on our Senior Credit Facility, and the use of debt and equity offerings under our shelf registration statement. Refer to Note 8, "Debt and Line of Credit," and Note 9, "Equity and Temporary Equity," in our accompanying Consolidated Financial Statements for additional information.

We also intend to continue to strengthen our capital and liquidity positions by focusing on our core fundamentals, which are generating positive cash flows from operations, maintaining appropriate debt levels and leverage ratios, and controlling overhead costs. We take a disciplined approach to selecting the optimal mix of financing sources to meet our liquidity demands and minimize our overall cost of capital. In June 2021, we received investment grade ratings of BBB and Baa3 with a stable outlook from S&P Global and Moody's, respectively. We plan on continuing to capitalize on our advantage in the credit markets to access a greater proportion of unsecured debt to optimize our cost of capital and increase our financial flexibility.

Acquisitions

Subject to market conditions, we intend to continue to identify opportunities to expand our development pipeline and acquire existing properties. We finance acquisitions through available cash, secured financing, draws on our Senior Credit Facility, the assumption of existing debt on properties and the issuance of debt and equity securities. We will continue to evaluate acquisition opportunities that meet our criteria. Refer to Note 3, "Real Estate Acquisitions and Dispositions," in the accompanying Consolidated Financial Statements for information regarding recent property acquisitions.

On April 8, 2022, we completed our previously announced acquisition of Park Holidays. The acquisition valued Park Holidays at an enterprise value of £950.0 million (or approximately $1.2 billion). As consideration for the acquisition, we (i) issued an aggregate of 186,044 shares of our common stock with a value of approximately $34.0 million as of the closing to certain individual sellers who are also members of Park Holidays' senior management team, and (ii) paid the remainder of the purchase price in cash.

Capital Expenditures

Our capital expenditures include expansion sites and development construction costs, recurring capital expenditures, lot modifications, growth projects, acquisition-related capital expenditures, rental home purchases and rebranding costs.

Our capital expenditure activity is summarized as follows (in millions):

	Six Months Ended
	June 30, 2022		June 30, 2021
Expansion and Development Expenditures	$	122.7	$	90.4
Recurring Capital Expenditures	33.4		27.6
Lot Modifications Expenditures	14.4		16.9
Growth Projects	49.5		36.4
Acquisition-related Capital Expenditures	123.1		70.7
Rental Program	59.0		53.8
Rebranding Cost	10.7		—
Other	(6.4)		4.6
Total capital expenditures activity	$	406.4	$	300.4

Expansion and development expenditures - consist primarily of construction costs such as roads, activities and amenities, and costs necessary to complete home and RV site improvements, such as driveways, sidewalks and landscaping at our MH communities and RV resorts. Expenditures also include costs to rebuild after damage has been incurred at MH, RV or Marina properties, and research and development.

63

SUN COMMUNITIES, INC.

Recurring capital expenditures - relate to our continued commitment to the upkeep of our MH and RV properties and include items such as dredging, dock repairs and improvements, and equipment maintenance and upgrades related to our marinas.

Lot modification capital expenditures - are incurred to modify the foundational structures required to set a new home after a previous home has been removed. These expenditures are necessary to create a revenue stream from a new site renter and often improve the quality of the community. Other lot modification expenditures include land improvements added to annual RV sites to aid in the conversion of transient RV guests to annual contracts.

Growth projects - consist of revenue generating or expense reducing activities at MH communities, RV resorts and Marinas. This includes, but is not limited to, utility efficiency and renewable energy projects, site, slip or amenity upgrades such as the addition of a garage, shed or boat lift, and other special capital projects that substantiate an incremental rental increase.

Acquisition-related capital expenditures - consist of capital improvements identified during due diligence that are necessary to bring our communities, resorts and marinas up to our operating standards. These include items such as: upgrading clubhouses; landscaping; new street light systems; new mail delivery systems; pool renovation including larger decks, heaters and furniture; new maintenance facilities; lot modifications; and new signage.

Rental program - investment in the acquisition of homes intended for the Rental Program and the purchase of vacation rental homes at our RV resorts. Expenditures for these investments depend upon the condition of the markets for repossessions and new home sales, rental homes and vacation rental homes.

Rebranding cost - includes new signage at our RV resorts and costs of building an RV mobile application and updated website.

Cash Flow Activities

Our cash flow activities are summarized as follows (in millions):

	Six Months Ended
	June 30, 2022		June 30, 2021
Net Cash Provided by Operating Activities	$	496.7	$	470.7
Net Cash Used for Investing Activities	$	(2,475.8)	$	(865.5)
Net Cash Provided by Financing Activities	$	2,092.2	$	421.5
Effect of Exchange Rate Changes on Cash, Cash Equivalents and Restricted Cash	$	(6.6)	$	0.3

Cash, cash equivalents, and restricted cash increased by $106.5 million from $78.2 million as of December 31, 2021, to $184.7 million as of June 30, 2022.

Operating activities - Net cash provided by operating activities increased by $26.0 million to $496.7 million for the six months ended June 30, 2022, compared to $470.7 million for the six months ended June 30, 2021. The increase was driven by improved operating performance at our existing properties and the addition of recently acquired properties.

Our net cash flows provided by operating activities from continuing operations may be adversely impacted by, among other things: (a) the market and economic conditions in our current markets generally, and specifically in the metropolitan areas of our current markets; (b) lower occupancy and rental rates of our properties; (c) increased operating costs, such as wage and benefit costs, insurance premiums, real estate taxes and utilities, that cannot be passed on to our tenants; (d) decreased sales of manufactured homes; (e) current volatility in economic conditions and the financial markets; and (f) the effects of the COVID-19 pandemic. See "Risk Factors" in Part I, Item 1A of our 2021 Annual Report.

Investing activities - Net cash used for investing activities increased by $1.6 billion to $2.5 billion for the six months ended June 30, 2022, compared to $865.5 million for the six months ended June 30, 2021. The increase in Net cash used for investing activities was primarily driven by an increase in cash deployed to acquire Park Holidays and other new properties, capital expenditure activity, and issuance of notes and other receivables during the six months ended June 30, 2022 as compared to the corresponding period in 2021. Refer to the Consolidated Statements of Cash Flow for detail on the net cash used for investing activities during the six months ended June 30, 2022 and 2021. Refer to Note 3, "Real Estate Acquisitions and Dispositions," and Note 4, "Notes and Other Receivables," in our accompanying Consolidated Financial Statements for additional information on acquisitions and issuance of notes and other receivables.

Financing activities - Net cash provided by financing activities increased by $1.7 billion to $2.1 billion for the six months ended June 30, 2022, compared to $421.5 million for the six months ended June 30, 2021. The increase in Net cash provided by financing activities was primarily driven by a decrease in payments and an increase in borrowings under our Senior Credit Facility during the six months ended June 30, 2022 as compared to the corresponding period in 2021. Refer to the Consolidated Statements of Cash Flow for detail on the net cash provided by financing activities during the six months ended June 30, 2022 and 2021. Refer to Note 8, "Debt and Line of Credit," and Note 9, "Equity and Temporary Equity," in our accompanying Consolidated Financial Statements for additional information.

Equity and Debt Activity

Public Equity Offerings

In November 2021, we entered into the November 2021 Forward Sale Agreements in connection with an underwritten registered public offering of 4,025,000 shares of our common stock at a public offering price of $185.00. On April 15, 2022, we completed the physical settlement of the 4,025,000 shares of common stock and received the aggregate net proceeds of $705.4 million. We used the net proceeds to repay borrowings outstanding under our Senior Credit Facility, and for working capital and general corporate purposes.

At the Market Offering Sales Agreement

In December 2021, we entered into the Sales Agreement, with certain sales agents and forward sellers pursuant to which we may sell, from time to time, up to an aggregate gross sales price of $1.25 billion of our common stock through the sales agents, acting as our sales agents or, if applicable, as forward sellers, or directly to the sales agents as principals for their own accounts. We simultaneously terminated our prior sales agreement upon entering into the Sales Agreement.

We entered into forward sales agreements with respect to 891,103 shares of common stock under our at the market offering program for $158.0 million during the six months ended June 30, 2022. We also entered into forward sale agreements with respect to 1,820,109 shares of common stock under our at the market offering program for $356.5 million during the year ended December 31, 2021. During the three months ended June 30, 2022, we completed the physical settlement of 1,200,000 shares of common stock and received net proceeds of $229.5 million.

Senior Unsecured Notes

In April 2022, the Operating Partnership issued $600.0 million of senior unsecured 2032 Notes with an interest rate of 4.2 percent and a 10-year term, due April 15, 2032. The net proceeds from the offering were $592.3 million after deducting underwriters' discounts and estimated offering expenses. In connection with the 2032 Notes issuance, we settled four 10-year Treasury rate locks totaling $600.0 million and received a settlement payment of $35.3 million. The balance will be amortized as a reduction of interest expense on a straight-line basis over the 10-year term of the hedged transaction. This lowers the effective interest rate on the 2032 Notes from 4.2 percent to 3.6 percent.

In October 2021, the Operating Partnership issued $450.0 million of senior unsecured 2028 Notes with an interest rate of 2.3 percent and a seven-year term, due November 1, 2028. The Operating Partnership also issued an additional $150.0 million of its 2031 Notes (as defined below). The net proceeds from both offerings were approximately $595.5 million after deducting underwriters' discounts and estimated offering expenses.

In June 2021, the Operating Partnership issued $600.0 million of senior unsecured 2031 Notes with an interest rate of 2.7 percent and a ten-year term, due July 15, 2031. The net proceeds from the offering were approximately $592.4 million, after deducting underwriters' discounts and estimated offering expenses.

The proceeds from the 2028 Notes, the 2031 Notes and the 2032 Notes, were used to pay down borrowings under our Senior Credit Facility. The total outstanding balance of senior unsecured notes was $1.8 billion at June 30, 2022.

65

SUN COMMUNITIES, INC.

The obligations of the Operating Partnership to pay principal, premiums, if any, and interest on the 2028 Notes, 2031 Notes and 2032 Notes are guaranteed on a senior basis by SUI. The irrevocable guarantee is full and unconditional, and the Operating Partnership is a consolidated subsidiary of the Company. Under Rule 3-10 of Regulation S-X, as amended, subsidiary issuers of obligations guaranteed by its parent company are not required to provide separate financial statements, provided that the subsidiary obligor is consolidated into the parent company's consolidated financial statements, the parent guarantee is "full and unconditional" and, subject to certain exceptions, the alternative disclosure required by Rule 13-01 is provided, which includes narrative disclosure and summarized financial information. Accordingly, separate consolidated financial statements of the Operating Partnership have not been presented. Furthermore, as permitted under Rule 13-01(a)(4)(vi), we have excluded the summarized financial information for the Operating Partnership as the assets, liabilities and results of operations of the Operating Partnership are not materially different from the corresponding amounts presented in our consolidated financial statements and management believes such summarized financial information would be repetitive and not provide incremental value to investors.

Line of Credit

In April 2022, in connection with the closing of the Park Holidays acquisition, the Operating Partnership as borrower, and SUI, as guarantor, and certain lenders entered into the Credit Facility Amendment, which amended our Senior Credit Facility.

The Credit Facility Amendment increased the aggregate amount of our Senior Credit Facility to $4.2 billion with the ability to upsize the total borrowings by an additional $800.0 million, subject to certain conditions. The increased aggregate amount under the Senior Credit Facility consists of the following: (a) a revolving loan in an amount up to $3.05 billion and (b) a term loan facility of $1.15 billion, with the ability to draw funds from the combined facilities in U.S. dollars, Pounds sterling, Euros, Canadian dollars and Australian dollars, subject to certain limitations. The Credit Facility Amendment extended the maturity date of the revolving loan facility to April 7, 2026. At our option that maturity date may be extended two additional six-month periods. In addition, the Credit Facility Amendment established the maturity date of the term loan facility under the Credit Facility Amendment as April 7, 2025, which may not be further extended.

Prior to the amendment, the Senior Credit Facility permitted aggregate borrowings of up to $2.0 billion, with an accordion feature that allowed for additional commitments of up to $1.0 billion, subject to the satisfaction of certain conditions. Prior to the amendment, $500.0 million of available borrowings under the Senior Credit Facility was scheduled to mature on October 11, 2024, with the remainder scheduled to mature on June 14, 2025. During the three months ended June 30, 2022 and 2021, we recognized losses on extinguishment of debt in our Consolidated Statements of Operations of $0.1 million related to the amendment of the Senior Credit Facility, and $0.2 million and $7.9 million related to the termination of our $750.0 million credit facility and the $1.8 billion credit facility between Safe Harbor and certain lenders, respectively.

The Senior Credit Facility bears interest at a floating rate based on Adjusted Term SOFR, the Adjusted Eurocurrency Rate, the Daily RFR, the Australian BBSY, the Daily SONIA Rate or the Canadian Dollar Offered Rate, as applicable, plus, in all cases, a margin, which can range from 0.725 percent to 1.6 percent, subject to certain adjustments. As of June 30, 2022, the margins based on our credit ratings were 0.85 percent on the revolving loan facility and 0.95 percent on the term loan facility.

At the lenders' option, the Senior Credit Facility will become immediately due and payable upon an event of default under the Credit Facility Amendment. We had $662.0 million of borrowings outstanding under the revolving loan and $1.1 billion of borrowings outstanding under the term loan on the Senior Credit Facility as of June 30, 2022. We had $1.0 billion of revolving borrowings on our prior Senior Credit Facility as of December 31, 2021. These balances are recorded in Unsecured debt on the Consolidated Balance Sheets.

The Senior Credit Facility provides us with the ability to issue letters of credit. Our issuance of letters of credit does not increase our borrowings outstanding under the Senior Credit Facility, but does reduce the borrowing amount available. We had $2.8 million and $2.2 million of outstanding letters of credit at June 30, 2022 and December 31, 2021, respectively.

Financial Covenants

Pursuant to the terms of the Senior Credit Facility, we are subject to various financial and other covenants. The most restrictive financial covenants for the Senior Credit Facility are as follows:

Covenant	Requirement	As of June 30, 2022
Maximum leverage ratio	<65.0%	31.8%
Minimum fixed charge coverage ratio	>1.40	4.22
Maximum dividend payout ratio	<95.0%	47.2%
Maximum secured leverage ratio	<40.0%	13.1%

In addition, we are required to maintain the following covenants with respect to the senior unsecured notes payable:

Covenant	Requirement	As of June 30, 2022
Total debt to total assets	≤60.0%	40.3%
Secured debt to total assets	≤40.0%	19.3%
Consolidated income available for debt service to debt service	≥1.50	5.67
Unencumbered total asset value to total unsecured debt	≥150.0%	344.3%

As of June 30, 2022, we were in compliance with the above covenants and do not anticipate that we will be unable to meet these covenants in the near term.

Bridge Loan Termination

In March 2022, we terminated our commitment letter with Citigroup, pursuant to which, Citigroup (on behalf of its affiliates), previously committed to lend us up to £950.0 million, or approximately $1.2 billion converted at the March 31, 2022 exchange rate (the "Bridge Loan"). As of the date of termination, we did not have any borrowings outstanding under the Bridge Loan.

Derivative Transactions

Our objective and strategy in using interest rate derivatives is to manage exposure to interest rate movements, thereby minimizing the effect of interest rate changes and the effect they could have on future cash outflows (forecasted interest payments) on a forecasted issuance of long-term debt. We do not enter into derivative instruments for speculative purposes.

In July 2022, we entered into two treasury lock contracts with an aggregate notional value of $200.0 million to hedge interest rate risk associated with the future issuance of long-term fixed rate debt. The benchmark interest rate used is the on-the-run 10-year U.S. Treasury. We also entered into interest rate swap agreements to hedge variable rate borrowings of £400.0 million under the term loan on the Senior Credit Facility. The interest rate swaps lock in a total fixed rate, inclusive of spread, of 3.67 percent through the term loan maturity date of April 7, 2025.

Long-term Financing and Capital Requirements

Long-term Financing

We anticipate meeting our long-term liquidity requirements, such as scheduled debt maturities, large property acquisitions, expansion and development of properties, other nonrecurring capital improvements and Operating Partnership unit redemptions through the long-term unsecured and secured indebtedness and the issuance of certain debt or equity securities subject to market conditions.

We had unrestricted cash on hand as of June 30, 2022, of $169.7 million. As of June 30, 2022, there was $2.3 billion of remaining capacity on the Senior Credit Facility. At June 30, 2022 we had a total of 472 unencumbered MH, RV and Marina properties.

67

SUN COMMUNITIES, INC.

From time to time, we may also issue shares of our capital stock, issue equity units in our Operating Partnership, issue unsecured notes, obtain other debt financing or sell selected assets. Our ability to finance our long-term liquidity requirements in such a manner will be affected by numerous economic factors affecting the MH, RV and Marina industries at the time, including the availability and cost of mortgage debt, our financial condition, the operating history of the properties, the state of the debt and equity markets, and the general national, regional and local economic conditions. When it becomes necessary for us to approach the credit markets, the volatility in those markets could make borrowing more difficult to secure, more expensive, or effectively unavailable. In the event our current credit ratings are downgraded, it may become difficult or more expensive to obtain additional financing or refinance existing unsecured indebtedness as maturities become due. See "Risk Factors" in Part I, Item 1A of our 2021 Annual Report. If we are unable to obtain additional debt or equity financing on acceptable terms, our business, results of operations and financial condition would be adversely impacted.

As of June 30, 2022, our net debt to enterprise value was 25.0 percent (assuming conversion of all common OP units, Series A-1 preferred OP units, Series A-3 preferred OP units, Series C preferred OP units, Series D preferred OP units, Series E preferred OP units, Series F preferred OP units, Series G preferred OP units, Series H preferred OP units, Series I preferred OP units and Series J preferred OP units to shares of common stock). Our debt has a weighted average interest rate of 3.4 percent and a weighted average years to maturity of 7.9 years.

Capital Requirements

Certain of our nonconsolidated affiliates, which are accounted for under the equity-method of accounting, have incurred indebtedness. We have not guaranteed the debt of our nonconsolidated affiliates in the arrangements referenced below, nor do we have any obligations to fund this debt should the nonconsolidated affiliates be unable to do so. Refer to Note 6, "Investments in Nonconsolidated Affiliates," in the accompanying Consolidated Financial Statements for additional information about these entities.

GTSC - During September 2019, GTSC entered into a warehouse line of credit with a maximum loan amount of $125.0 million. During September 2020, May 2021 and December 2021, the maximum amount was increased to $180.0 million, $230.0 million and $255.0 million, respectively, with an option to increase to $275.0 million subject to the lender's consent. As of June 30, 2022, and December 31, 2021 the aggregate carrying amount of debt, including both our and our partner's share, incurred by GTSC was $267.7 million (of which our proportionate share is $107.1 million) and $243.1 million (of which our proportionate share is $97.2 million), respectively. The debt bears interest at a variable rate based on a Commercial Paper or adjusted Secured Overnight Financing Rate plus 1.65 percent per annum and matures on December 15, 2025.

Sungenia JV - During May 2020, the Sungenia JV entered into a debt facility agreement with a maximum loan amount of $27.0 million Australian dollars, or $18.6 million converted at the June 30, 2022 exchange rate. As of June 30, 2022 and December 31, 2021, the aggregate carrying amount of debt, including both our and our partners' share, incurred by Sungenia JV was $6.0 million (of which our proportionate share is approximately $3.0 million), and $6.3 million (of which our proportionate share is $3.1 million), respectively. The debt bears interest at a variable rate based on the BBSY rate plus 2.05 percent per annum and is available for a minimum of three years.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market risk is the exposure to loss resulting from changes in market factors such as interest rates, foreign currency exchange rates, commodity prices and equity prices.

Interest Rate Risk

Our principal market risk exposure is interest rate risk. We mitigate this risk by maintaining prudent amounts of leverage, minimizing capital costs and interest expense while continuously evaluating all available debt and equity resources and following established risk management policies and procedures, which include the periodic use of derivatives. Our primary strategy in entering into derivative contracts is to minimize the variability that interest rate changes could have on our future cash flows. From time to time, we employ derivative instruments that effectively convert a portion of our variable rate debt to fixed rate debt. We do not enter into derivative instruments for speculative purposes.

Our variable rate debt totaled $1.7 billion and $231.5 million as of June 30, 2022 and 2021, respectively. As of June 30, 2022, our variable debt bore interest at the Adjusted Term SOFR, the Adjusted Eurocurrency Rate, the Daily RFR, the Australian BBSY rate, the Daily SONIA Rate or the Canadian Dollar Offered Rate, and the Eurodollar rate or Prime rate plus a margin. As of June 30, 2021, our variable debt bore interest at the Adjusted Eurocurrency Rate, the Australian BBSY rate, and the Eurodollar rate or Prime rate plus a margin. If the above rate increased or decreased by 1.0 percent, our interest expense would have increased or decreased by $6.8 million and $5.8 million for the six months ended June 30, 2022 and 2021, respectively, based on the $1.4 billion and $1.2 billion average balances outstanding under our variable rate debt facilities, respectively.

Foreign Currency Exchange Rate Risk

Foreign currency exchange rate risk is the risk that fluctuations in currencies against the U.S. dollar will negatively impact our results of operations. We are exposed to foreign currency exchange rate risk as a result of remeasurement and translation of the assets and liabilities of our properties in the UK and Canada, and our equity investment and joint venture in Australia, into U.S. dollars. Fluctuations in foreign currency exchange rates can therefore create volatility in our results of operations and may adversely affect our financial condition.

At June 30, 2022 and December 31, 2021, our shareholder's equity included $1.2 billion from our investments and operations in Canada, Australia and the United Kingdom and $663.6 million from our investments and operations in Canada and Australia, which collectively represented 15.4 percent and 9.9 percent of total shareholder's equity, respectively. Based on our sensitivity analysis, a 10.0 percent strengthening of the U.S. dollar against the Canadian dollar, Australian dollar and Pounds sterling would have caused a reduction of $115.9 million and $66.4 million to our total shareholder's equity at June 30, 2022 and December 31, 2021, respectively.

Capital Market Risk

We are exposed to risks related to the equity capital markets, and our related ability to raise capital through the issuance of our common stock or other equity instruments. We are also exposed to risks related to the debt capital markets, and our related ability to finance our business through borrowings under other financing arrangements. As a REIT, we are required to distribute a significant portion of our taxable income annually, which constrains our ability to accumulate operating cash flow and therefore requires us to utilize debt or equity capital to finance our business. We seek to mitigate these risks by monitoring the debt and equity capital markets to inform our decisions on the amount, timing and terms of capital we raise.

ITEM 4.  CONTROLS AND PROCEDURES

Evaluation of disclosure controls and procedures

We maintain disclosure controls and procedures designed to provide reasonable assurance that information required to be disclosed in reports filed under the Exchange Act is recorded, processed, summarized and reported within the specified time periods and accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

Our management, with the participation of our CEO and CFO, evaluated the effectiveness of our disclosure controls and procedures (pursuant to Rules 13a-15(e) or 15d-15(e) of the Exchange Act) at June 30, 2022. Based upon this evaluation, our CEO and CFO concluded that our disclosure controls and procedures were effective as of June 30, 2022.

On April 8, 2022, we completed the acquisition of Park Holidays and are currently integrating Park Holidays into our operations, compliance program and internal control processes. Park Holidays constituted approximately 15 percent of our total assets as of June 30, 2022, including the goodwill and other intangible assets recorded as part of the purchase price allocation, and 8 percent of our revenues for the six months ended June 30, 2022. SEC regulations allow companies to exclude acquisitions from their assessment of internal control over financial reporting during the first year following an acquisition. We have excluded the acquired operations of Park Holidays from our assessment of our internal control over financial reporting for the six months ended June 30, 2022.

Changes in internal control over financial reporting

There were no changes in our internal control over financial reporting during the three months ended June 30, 2022 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

Sun Communities, Inc., a Maryland corporation, and all wholly-owned or majority-owned and controlled subsidiaries, including Sun Communities Operating Limited Partnership (the "Operating Partnership"), Sun Home Services, Inc. ("SHS"), Safe Harbor Marinas, LLC ("Safe Harbor") and Tiger Topco 1 Limited (together with its subsidiaries, "Park Holidays") are referred to herein as the "Company," "SUI," "us," "we," and "our."

We follow accounting standards set by the Financial Accounting Standards Board ("FASB"). FASB establishes accounting principles generally accepted in the United States of America ("GAAP"), which we follow to ensure that we consistently report our financial condition, results of operations and cash flows. References to GAAP issued by the FASB in these footnotes are to the FASB Accounting Standards Codification ("ASC"). These unaudited Consolidated Financial Statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC") for interim financial information and in accordance with GAAP. We present interim disclosures and certain information and footnote disclosures as required by SEC rules and regulations. Accordingly, the unaudited Consolidated Financial Statements do not include all of the information and footnotes required by GAAP for complete financial statements. The accompanying unaudited Consolidated Financial Statements reflect, in the opinion of management, all adjustments, including adjustments of a normal and recurring nature, necessary for a fair presentation of the interim financial statements. All intercompany transactions have been eliminated in consolidation.

Certain prior period amounts have been revised to conform with current presentation, with no effect on net income. These include reclassification of certain revenues and expenses between Real property and Service, retail, dining and entertainment within our Marina Portfolio. There was no impact to prior period net income, shareholders equity or cash flows for any of the reclassifications. Further, the reclassification had no impact on previously reported total marina Net Operating Income ("NOI").

The results of operations for interim periods are not necessarily indicative of results that may be expected for any other interim period or for the full year. These unaudited Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2021 as filed with the SEC on February 22, 2022 (our "2021 Annual Report"). These statements have been prepared on a basis that is substantially consistent with the accounting principles applied in our 2021 Annual Report.

Our three reportable segments are: (i) Manufactured home ("MH") communities, (ii) Recreational vehicle ("RV") resorts and (iii) Marina.

Variable Interest Entity Disclosure

The Operating Partnership

We consolidate the Operating Partnership under the guidance set forth in ASC 810, "Consolidation." We evaluated whether the Operating Partnership met the criteria for classification as a variable interest entity ("VIE") or, alternatively, as a voting interest entity and concluded that the Operating Partnership met the criteria of a VIE. Our significant asset is our investment in the Operating Partnership, and consequently, substantially all of our assets and liabilities represent those assets and liabilities of the Operating Partnership. We are the sole general partner and generally have the power to manage and have complete control over the Operating Partnership and the obligation to absorb its losses or the right to receive its benefits.

Other Consolidated VIEs

We consolidate Sun NG RV Resorts LLC ("Sun NG Resorts"); Sun NG Whitewater RV Resorts LLC; FPG Sun Menifee 80 LLC, SHM South Fork JV, LLC; Sun Solar Energy Project LLC, Sun Solar Energy Project CA II, and FPG Sun Moreno Valley 66 LLC under the guidance set forth in ASC Topic 810, "Consolidation." We concluded that each entity is a VIE where we are the primary beneficiary, as we have the power to direct the significant activities of and absorb the significant losses and receive the significant benefits from each entity. Refer to Note 8, "Debt and Line of Credit," for additional information on Sun NG Resorts.

During the three months ended June 30, 2022, we acquired the noncontrolling equity interest held by third parties in Rudgate Village SPE LLC, Rudgate Clinton SPE LLC and Rudgate Clinton Estates, LLC (collectively, "Rudgate"), an MH community, which resulted in the Company owning a 100 percent ownership interest in Rudgate. We concluded that Rudgate was no longer a VIE. Refer to Note 9, "Equity and Temporary Equity," for additional information.

The following table summarizes the assets and liabilities of our consolidated VIEs, with the exception of the Operating Partnership, included in our Consolidated Balance Sheets after eliminations (in millions):

	June 30, 2022		December 31, 2021

Temporary equity	42.6		35.4
Noncontrolling interests	4.1		19.4
Total Liabilities and Other Equity	$	169.1	$	236.6

Total assets related to the consolidated VIEs, with the exception of the Operating Partnership, comprised 4.4 percent and 4.9 percent of our consolidated total assets at June 30, 2022 and December 31, 2021, respectively. Total liabilities comprised 1.4 percent and 2.8 percent of our consolidated total liabilities at June 30, 2022 and December 31, 2021, respectively. Equity Interests and Noncontrolling interests related to the consolidated VIEs, on an absolute basis, comprised less than 1.0 percent of our consolidated total equity at June 30, 2022 and December 31, 2021, respectively.

The mortgage term loans, which total $3.3 billion as of June 30, 2022, are secured by 189 properties comprised of 74,682 sites representing approximately $3.1 billion of net book value.

Unsecured Debt

Senior Unsecured Notes

In April 2022, the Operating Partnership issued $600.0 million of senior unsecured notes with an interest rate of 4.2 percent and a 10-year term, due April 15, 2032 (the "2032 Notes"). Interest on the 2032 Notes is payable semi-annually in arrears on April 15 and October 15 of each year, beginning on October 15, 2022. The net proceeds from the offering were $592.3 million after deducting underwriters' discounts and estimated offering expenses. We used the net proceeds from the offering to repay borrowings outstanding under our Senior Credit Facility (as defined below).

In October 2021, the Operating Partnership issued $450.0 million of senior unsecured notes with an interest rate of 2.3 percent and a seven-year term, due November 1, 2028 (the "2028 Notes"). Interest on the 2028 Notes is payable semi-annually in arrears on May 1 and November 1 of each year, beginning on May 1, 2022. The Operating Partnership also issued an additional $150.0 million of its 2031 Notes (as defined below). The net proceeds from both offerings were approximately $595.5 million after deducting underwriters' discounts and estimated offering expenses. The proceeds were used to pay down borrowings under our Senior Credit Facility.

In June 2021, the Operating Partnership issued $600.0 million of senior unsecured notes with an interest rate of 2.7 percent and a ten-year term, due July 15, 2031 (the "2031 Notes"). Interest on the 2031 Notes is payable semi-annually in arrears on January 15 and July 15 of each year, beginning on January 15, 2022. The net proceeds from the offering were approximately $592.4 million, after deducting underwriters' discounts and estimated offering expenses. The proceeds were used to pay down borrowings under our Senior Credit Facility.

The total outstanding principal balance of senior unsecured notes was $1.8 billion at June 30, 2022. This balance is recorded in the Unsecured debt line item on the Consolidated Balance Sheets.

Line of Credit

In April 2022, in connection with the closing of the Park Holidays acquisition, the Operating Partnership as borrower, and SUI, as guarantor, and certain lenders entered into Amendment No. 1 to the Fourth Amended and Restated Credit Agreement and Other Loan Documents (the "Credit Facility Amendment"), which amended our senior credit facility (the "Senior Credit Facility").

The Credit Facility Amendment increased the aggregate amount of our Senior Credit Facility to $4.2 billion with the ability to upsize the total borrowings by an additional $800.0 million, subject to certain conditions. The increased aggregate amount under the Senior Credit Facility consists of the following: (a) a revolving loan in an amount up to $3.05 billion and (b) a term loan facility of $1.15 billion, with the ability to draw funds from the combined facilities in U.S. dollars, Pounds sterling, Euros, Canadian dollars and Australian dollars, subject to certain limitations. The Credit Facility Amendment extended the maturity date of the revolving loan facility to April 7, 2026. At our option that maturity date may be extended two additional six-month periods. In addition, the Credit Facility Amendment established the maturity date of the term loan facility under the Credit Facility Amendment as April 7, 2025, which may not be further extended.

Prior to the Credit Facility Amendment, the Senior Credit Facility permitted aggregate borrowings of up to $2.0 billion, with an accordion feature that allowed for additional commitments of up to $1.0 billion, subject to the satisfaction of certain conditions. Prior to the amendment, $500.0 million of available borrowings under the Senior Credit Facility were scheduled to mature on October 11, 2024, with the remainder scheduled to mature on June 14, 2025. During the three months ended June 30, 2022 and 2021, we recognized losses on extinguishment of debt in our Consolidated Statements of Operations of $0.1 million related to the amendment of the Senior Credit Facility, and $0.2 million and $7.9 million, related to the termination of our $750.0 million credit facility and the $1.8 billion credit facility between Safe Harbor and certain lenders, respectively.

The Senior Credit Facility bears interest at a floating rate based on Adjusted Term Secured Overnight Financing Rate ("SOFR"), the Adjusted Eurocurrency Rate, the Daily Risk Free Rate ("RFR"), the Australian Bank Bill Swap Bid Rate ("BBSY"), the Daily Sterling Overnight Index Average ("SONIA") Rate or the Canadian Dollar Offered Rate, as applicable, plus, in all cases, a margin, which can range from 0.725 percent to 1.6 percent, subject to certain adjustments. As of June 30, 2022, the margins based on our credit ratings were 0.85 percent on the revolving loan facility and 0.95 percent on the term loan facility.

At the lenders' option, the Senior Credit Facility will become immediately due and payable upon an event of default under the Credit Facility Amendment. We had $662.0 million of borrowings outstanding under the revolving loan and $1.1 billion of borrowings outstanding under the term loan on the Senior Credit Facility as of June 30, 2022. We had $1.0 billion of revolving borrowings on our prior Senior Credit Facility as of December 31, 2021. These balances are recorded in Unsecured debt on the Consolidated Balance Sheets.

The Senior Credit Facility provides us with the ability to issue letters of credit. Our issuance of letters of credit does not increase our borrowings outstanding under the Senior Credit Facility, but does reduce the borrowing amount available. We had $2.8 million and $2.2 million of outstanding letters of credit at June 30, 2022 and December 31, 2021, respectively.

Bridge Loan Termination

In March 2022, we terminated our commitment letter with Citigroup Global Markets, Inc. ("Citigroup"), pursuant to which Citigroup (on behalf of its affiliates) previously committed to lend us up to £950.0 million, or approximately $1.2 billion converted at the March 31, 2022 exchange rate (the "Bridge Loan"). As of the date of termination, we did not have any borrowings outstanding under the Bridge Loan. During the three months ended March 31, 2022, we recognized a Loss on extinguishment of debt in our Consolidated Statement of Operations of $0.3 million related to the termination of the Bridge Loan.

Unsecured Term Loan

In October 2019, we assumed a $58.0 million secured term loan facility related to an acquisition. The term loan has a four-year term ending October 29, 2023, and bears interest at a floating rate based on the Eurodollar rate or Prime rate plus a margin ranging from 1.20 percent to 2.05 percent. Effective July 1, 2021, the agreement was amended to release the associated collateral. The amendment extended the term loan facility maturity date to October 29, 2025 and adjusted the interest rate margin to a range from 0.8 percent to 1.6 percent. As of June 30, 2022, the margin was 0.95 percent. The outstanding balance was $24.6 million at June 30, 2022 and $31.6 million at December 31, 2021. These balances are recorded in Unsecured debt and Secured debt on the Consolidated Balance Sheets, respectively.

Preferred Equity - Sun NG Resorts - Mandatorily Redeemable

In connection with the investment in Sun NG Resorts in June 2018, $35.3 million of mandatorily redeemable Preferred Equity ("Preferred Equity - Sun NG Resorts") was purchased by unrelated third parties. The Preferred Equity - Sun NG Resorts carries a preferred rate of return of 6.0 percent per annum. The Preferred Equity - Sun NG Resorts has a seven-year term ending June 1, 2025 and can be redeemed in the fourth quarter of 2024 at the holders' option. The Preferred Equity - Sun NG Resorts as of June 30, 2022 was $35.2 million. This balance is recorded within the Unsecured debt line item on the Consolidated Balance Sheets. Refer to Note 7, "Consolidated Variable Interest Entities," for additional information.

Preferred OP Units - Mandatorily Redeemable

Preferred OP units at June 30, 2022 and December 31, 2021 include $34.7 million of Aspen preferred OP units issued by the Operating Partnership. As of June 30, 2022, these units are convertible indirectly into 402,003 shares of our common stock.

In January 2020, we amended the Operating Partnership's partnership agreement. The amendment extended the automatic redemption date and reduced the annual distribution rate for 270,000 of the Aspen preferred OP units (the "Extended Units"). Subject to certain limitations, at any time prior to January 1, 2024 (or prior to January 1, 2034 with respect to the Extended Units), the holder of each Aspen preferred OP unit at its option may convert such Aspen preferred OP unit into: (a) if the average closing price of our common stock for the preceding ten trading days is $68.00 per share or less, 0.397 common OP units; or (b) if the ten-day average closing price is greater than $68.00 per share, the number of common OP units is determined by dividing (i) the sum of (A) $27.00 plus (B) 25.0 percent of the amount by which the ten-day average closing price exceeds $68.00 per share, by (ii) the ten-day average closing price. The current preferred distribution rate is 3.8 percent on the Extended Units and 6.5 percent on all other Aspen preferred OP units. On January 2, 2024 (or January 2, 2034 with respect to the Extended Units), we are required to redeem for cash all Aspen preferred OP units that have not been converted to common OP units. As of June 30, 2022, 270,000 of the Extended Units and 1,013,819 other Aspen preferred units were outstanding. These balances are recorded within the Unsecured debt line item on the Consolidated Balance Sheets.

Covenants

The mortgage term loans, senior unsecured notes and Senior Credit Facility are subject to various financial and other covenants. The most restrictive covenants are pursuant to (a) the terms of the Senior Credit Facility, which contains a minimum fixed charge coverage ratio, maximum leverage ratio, distribution ratio and variable rate indebtedness, and (b) the terms of the senior unsecured notes, which contain a total debt to total assets ratio, secured debt to total assets ratio, consolidated income available for debt service to debt service ratio and unencumbered total asset value to unsecured debt covenants ratio. At June 30, 2022, we were in compliance with all covenants.

In addition, certain of our subsidiary borrowers own properties that secure loans. These subsidiaries are consolidated within our accompanying Consolidated Financial Statements, however, each of these subsidiaries' assets and credit are not available to satisfy our debts and other obligations, and any of our other subsidiaries or any other person or entity.

Equity Interest - NG Sun LLC - In June 2018, in connection with the investment in Sun NG Resorts, unrelated third parties purchased $6.5 million of Series B preferred equity interests and $15.4 million of common equity interests in Sun NG Resorts (herein jointly referred to as "Equity Interest - NG Sun LLC"). In April and September 2020, in connection with certain acquisitions, $3.0 million of Series B preferred equity interests were converted to common equity interests. The Series B preferred equity interests carry a preferred return at a rate that, at any time, is equal to the interest rate on Sun NG Resorts' indebtedness at such time. The current rate of return is 5.0 percent. The Equity Interest - NG Sun LLC does not have a fixed maturity date and can be redeemed in the fourth quarters of 2024, 2025 or 2026 at the holders' option. Sun NG LLC, our subsidiary, has the right during certain periods each year, with or without cause, or for cause at any time, to elect to buy NG Sun LLC's interest. During a limited period in 2024, NG Sun LLC has the right to put its interest to Sun NG LLC. If either party exercises its option, the property management agreement will be terminated, and we are required to purchase the remaining interests of NG Sun LLC and the property management agreement at fair value. In December 2021, the operating agreement was amended and we paid Sun NG Resorts a contingent consideration earnout in the amount of $38.3 million. The contingent consideration payment was recognized as an additional purchase price payment within Land improvements and buildings in the Consolidated Balance Sheets, and within Acquisition of properties, net of cash acquired in the Consolidated Statement of Cash Flows. The Equity Interest - NG Sun LLC balance was $28.9 million and $24.7 million as of June 30, 2022 and December 31, 2021, respectively. Refer to Note 7, "Consolidated Variable Interest Entities," and Note 8, "Debt and Line of Credit," for additional information.

Permanent Equity

Universal Shelf Registration Statement

In April 2021, we filed a new universal shelf registration statement on Form S-3 with the SEC. The shelf registration statement was deemed automatically effective and provides for the registration of unspecified amounts of equity and debt securities. We have the authority to issue 200,000,000 shares of capital stock, of which 180,000,000 shares are common stock and 20,000,000 are shares of preferred stock, par value $0.01 per share. As of June 30, 2022, we had 121,644,228 shares of common stock issued and outstanding and no shares of preferred stock were issued and outstanding.

Public Equity Offerings

In November 2021, we entered into two forward sale agreements relating to an underwritten registered public offering of 4,025,000 shares of our common stock at a public offering price of $185.00 per share and completed the offering on November 18, 2021 (the "November 2021 Forward Sale Agreements"). We did not initially receive any proceeds from the sale of shares of our common stock by the forward purchaser or its affiliates. On April 15, 2022, we completed the physical settlement of the 4,025,000 shares of common stock and received aggregate net proceeds of $705.4 million. We used the net proceeds to repay borrowings outstanding under our Senior Credit Facility, and for working capital and general corporate purposes.

At the Market Offering Sales Agreement

In December 2021, we entered into an At the Market Offering Sales Agreement with certain sales agents and forward sellers pursuant to which we may sell, from time to time, up to an aggregate gross sales price of $1.25 billion of our common stock (the "Sales Agreement"), through the sales agents, acting as our sales agents or, if applicable, as forward sellers, or directly to the sales agents as principals for their own accounts. The sales agents and forward sellers are entitled to compensation in an agreed amount not to exceed 2.0 percent of the gross price per share for any shares sold under the Sales Agreement. We simultaneously terminated our prior sales agreement upon entering into the Sales Agreement.

During the three months ended March 31 and June 30, 2022, we entered into forward sales agreements with respect to 600,503 shares of common stock for $107.9 million, and 290,600 shares of common stock for $50.1 million, respectively, under our at the market offering program. These forward sale agreements were not settled as of June 30, 2022, but we expect to settle them by the end of March and June 2023, respectively.

During the year ended December 31, 2021, we entered into forward sale agreements with respect to 1,820,109 shares of common stock under our prior at the market offering program for $356.5 million. During the three months ended June 30, 2022, we completed the physical settlement of 1,200,000 shares of common stock and received net proceeds of $229.5 million. We expect to settle the remaining 620,109 shares of common stock by the end of September 2022.

Refer to Note 19, "Subsequent Events," for information regarding the settlement of certain forward sale agreements outstanding under our at the market offering program after June 30, 2022.

Issuances of Common Stock and OP Units in Connection with the Acquisition of Certain Properties

Issuance of Common Stock

On April 8, 2022, we issued an aggregate of 186,044 shares of our common stock in connection with the acquisition of Park Holidays.

Issuances of Common OP Units

Six Months Ended June 30, 2022 and 2021	Common OP Units Issued		Related Acquisition
May 2022	10,854	(1)	Rudgate
May 2022	5,605		Kittery Point
February 2022	14,683		Jarrett Bay Boatworks

(1) During the three months ended June 30, 2022, we acquired the noncontrolling equity interest held by third parties in Rudgate for a total purchase price of $3.1 million. As consideration, we issued 10,854 common OP units and paid the remainder of the purchase price in cash. The acquisition resulted in the Company owning a 100 percent controlling interest in Rudgate. The acquisition was accounted for as an equity transaction in accordance with ASC Topic 810, "Consolidation," with the difference between the purchase price and the acquired noncontrolling interest of $13.2 million recorded as an increase to Additional Paid-in Capital on the Consolidated Balance Sheets. Refer to Note 7, "Consolidated Variable Interest Entities," for additional information.

Issuances of Preferred OP Units

Issuance of Series E Preferred OP Units - In January 2020, we issued 90,000 Series E preferred OP units in connection with the acquisition of Sun Outdoors Cape Cod. The Series E preferred OP units have a stated issuance price of $100.00 per OP unit and carry a preferred return of 5.25 percent until the second anniversary of the issuance date. Commencing with the second anniversary of the issuance date, the Series E preferred OP units carry a preferred return of 5.5 percent. Commencing with the first anniversary of the issuance date, subject to certain limitations, each Series E preferred OP unit can be exchanged for our common stock equal to the quotient obtained by dividing $100.00 by $145.00 (as such ratio is subject to adjustments for certain capital events). As of June 30, 2022, 85,000 Series E preferred OP units were outstanding.

Conversions

Conversions to Common Stock - Subject to certain limitations, holders can convert certain series of OP units to shares of our common stock at any time. Below is the activity of conversions during the six months ended June 30, 2022 and 2021:

Share-Based Compensation

6 Months Ended

Share-Based Payment Arrangement, Noncash Expense [Abstract]

Share-Based Compensation

As of June 30, 2022, we had two share-based compensation plans: the Sun Communities, Inc. 2015 Equity Incentive Plan (as amended, the "2015 Equity Incentive Plan") and the First Amended and Restated 2004 Non-Employee Director Option Plan (as amended, the "2004 Non-Employee Director Option Plan"). We believe granting equity awards will provide certain executives, key employees and directors additional incentives to promote our financial success and promote employee and director retention by providing an opportunity to acquire or increase the direct proprietary interest of those individuals in our operations and future. Time based awards for directors generally vest over three years. Time based awards for key employees and executives generally vest over five years. Market condition awards for the executives generally vest after three years.

First Amendment to the 2015 Equity Incentive Plan

At our 2022 Annual Meeting on May 17, 2022, our shareholders approved the First Amendment to the 2015 Equity Incentive Plan. The First Amendment increased the number of shares of common stock that may be issued under the 2015 Equity Incentive Plan to 4,750,000. As of June 30, 2022, there were 3,130,389 shares available for future issuance.

United Kingdom Sub-Plan

On April 6, 2022, the Board of Directors adopted the UK Sub-Plan under the 2015 Equity Incentive Plan, which is solely applicable to employee participants located in the UK, and establishes certain rules and limitations for participation in the 2015 Equity Incentive Plan by UK employees for the purpose of complying with applicable UK laws.

During the six months ended June 30, 2022 and 2021, shares were granted as follows:

Segment Reporting [Abstract]

Segment Reporting

ASC Topic 280, "Segment Reporting," establishes standards for the way the business enterprises report information about operating segments in its financial statements. As described in Note 1, "Basis of Presentation," we analyze our operating results through the following segments: (i) Manufactured home ("MH") communities, (ii) Recreational vehicle ("RV") resorts and (iii) Marina.

The MH segment owns, operates, develops, or has an interest in, a portfolio of MH communities throughout the U.S. and a portfolio of holiday parks throughout the UK, and is in the business of acquiring, operating and developing ground-up MH communities to provide affordable housing solutions to residents. The MH segment also provides manufactured home sales and leasing services to tenants and prospective tenants of our communities.

The RV segment owns, operates, develops, or has an interest in, a portfolio of RV resorts and is in the business of acquiring, operating and developing ground up RV resorts throughout the U.S. and in Canada. It also provides leasing services for vacation rentals within the RV resorts.

Properties containing both MH and RV sites are classified to a segment based on the predominant site counts at the properties.

The Marina segment owns, operates, and develops marinas, and is in the business of acquiring and operating marinas throughout the U.S., with the majority of such marinas concentrated in coastal regions, and others located in various inland regions and Puerto Rico.

A presentation of segment financial information is summarized as follows (in millions):

Income Taxes

6 Months Ended

Income Tax Disclosure [Abstract]

Income Taxes

We have elected to be taxed as a real estate investment trust ("REIT") pursuant to Section 856(c) of the Internal Revenue Code of 1986, as amended ("Code"). In order for us to qualify as a REIT, at least 95 percent of our gross income in any year must be derived from qualifying sources. In addition, a REIT must distribute annually at least 90 percent of its REIT taxable income (calculated without any deduction for dividends paid and excluding capital gain) to its shareholders and meet other tests.

Qualification as a REIT involves the satisfaction of numerous requirements (on an annual and quarterly basis) established under highly technical and complex Code provisions for which there are limited judicial or administrative interpretations and involves the determination of various factual matters and circumstances not entirely within our control. In addition, frequent changes occur in the area of REIT taxation, which requires us to continually monitor our tax status. We analyzed the various REIT tests and confirmed that we continued to qualify as a REIT for the six months ended June 30, 2022.

As a REIT, we generally will not be subject to United States ("U.S.") federal income taxes at the corporate level on the ordinary taxable income we distribute to our shareholders as dividends. If we fail to qualify as a REIT in any taxable year, our taxable income could be subject to U.S. federal income tax at regular corporate rates. Even if we qualify as a REIT, we may be subject to certain state and local income taxes, as well as U.S. federal income and excise taxes on our undistributed income. In addition, taxable income from non-REIT activities managed through taxable REIT subsidiaries is subject to federal, state and local income taxes. We are also subject to local income taxes in Canada, Puerto Rico and the United Kingdom due to certain properties located in those jurisdictions. We do not provide for withholding taxes on our undistributed earnings from our Canadian subsidiaries as they are reinvested and will continue to be reinvested indefinitely outside of the U.S. However, we are subject to Australian withholding taxes on distributions from our investment in Ingenia Communities Group. As currently structured, we are not subject to UK withholding taxes on distributions from our United Kingdom properties.

Deferred tax assets and liabilities reflect the impact of temporary differences between the amounts of assets and liabilities for financial reporting purposes and the basis of such assets and liabilities as measured by tax laws. Deferred tax assets are reduced, if necessary, by a valuation allowance to the amount where realization is more likely than not assured after considering all available evidence. Our temporary differences primarily relate to net operating loss carryforwards, depreciation and basis differences between tax and GAAP. Our deferred tax assets that have a full valuation allowance relate to our taxable REIT subsidiaries. As of June 30, 2022, we had $237.0 million of net deferred tax liabilities, comprised of deferred tax assets, net of valuation allowance, of $2.9 million, and deferred tax liabilities of $239.9 million. The deferred tax liability balance is comprised primarily of basis differences in our foreign investment in properties in the United Kingdom and Canada. As of December 31, 2021, we had $20.7 million of net deferred tax liabilities, comprised of deferred tax assets, net of valuation allowance, of $3.0 million, and deferred tax liabilities of $23.7 million. These balances include a net deferred tax asset, net of valuation allowance, in the United States of $1.2 million as of June 30, 2022 and December 31, 2021. The net deferred tax assets and deferred tax liabilities are recorded within Other Assets and Other Liabilities, respectively, on our Consolidated Balance Sheets as of June 30, 2022 and December 31, 2021.

We had no unrecognized tax benefits as of June 30, 2022 and during 2021. We do not expect significant changes in tax positions that would result in unrecognized tax benefits within one year of June 30, 2022.

For the three and six months ended June 30, 2022, we recorded current tax expense for federal, state, Canadian, Puerto Rican, UK income taxes and Australian withholding taxes totaling $3.9 million and $5.2 million, respectively. For the three and six months ended June 30, 2021, we recorded current tax expense for federal, state, Canadian income taxes and Australian withholding taxes totaling $1.2 million and $1.0 million, respectively.

For the three and six months ended June 30, 2022, we recorded a deferred tax benefit of $0.3 million, respectively. For the six months ended June 30, 2021, we recorded

Earnings Per Share

6 Months Ended

Jun. 30, 2022

Earnings Per Share [Abstract]

Earnings Per Share

Earnings per share ("EPS") is computed by dividing net income by the weighted average number of common shares outstanding during the period on a basic and diluted basis. We calculate diluted EPS using the more dilutive of the treasury stock method and the two-class method for stock option and restricted common shares, the treasury stock method for forward equity sales and the if converted method for convertible units.

From time to time, we enter into forward equity sales agreements, which are discussed in Note 9, "Equity and Temporary Equity." We considered the potential dilution resulting from the forward equity sales agreements on the EPS calculations. At inception, the agreements do not have an effect on the computation of basic EPS as no shares are delivered unless there is a physical settlement. Common shares issued upon the physical settlement of the forward equity sales agreements, weighted for the period these common shares are outstanding, are included in the denominator of basic EPS. To determine the dilution resulting from the forward equity sales agreements during the period of time prior to settlement, we calculate the number of weighted-average shares outstanding - diluted.

Our potentially dilutive securities include our potential common shares related to our forward equity offerings, our unvested restricted common shares, and our Operating Partnership outstanding common OP units, Series A-1 preferred OP units, Series A-3 preferred OP units, Series C preferred OP units, Series D preferred OP units, Series E preferred OP units, Series F preferred OP units, Series G preferred OP units, Series H preferred OP units, Series I preferred OP units, Series J preferred OP units and Aspen preferred OP Units, which, if converted or exercised, may impact dilution.

Diluted EPS considers the impact of potentially dilutive securities except when the potential common shares have an anti-dilutive effect. Our unvested restricted stock common shares contain rights to receive non-forfeitable distributions and participate equally with common stock with respect to distributions issued or declared, and thus, are participating securities, requiring the two-class method of computing EPS. In calculating the two-class method, undistributed earnings are allocated to both common shares and participating securities based on the weighted average number of shares outstanding during the period. The two-class method determines EPS by (1) dividing the sum of distributed earnings allocated to common shareholders and undistributed earnings allocated to common shareholders by the weighted average number of shares of common stock outstanding for the period; and (2) dividing the sum of distributed earnings allocated to participating securities and undistributed earnings allocated to participating securities by the weighted average number of shares of participating securities for the period. The remaining potentially dilutive common shares do not contain rights to distributions and are included in the computation of diluted EPS.

Computations of basic and diluted EPS were as follows (in millions, except for per share data):

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments And Hedging Activities

Our objective and strategy in using interest rate derivatives is to manage exposure to interest rate movements, thereby minimizing the effect of interest rate changes and the effect they could have on future cash outflows (forecasted interest payments) on a forecasted issuance of long-term debt. Treasury locks are used to accomplish this objective. We do not enter into derivative instruments for speculative purposes.

We designated the treasury lock contracts as cash flow hedges under ASC Topic 815, "Derivatives and Hedging." The risk being hedged is the interest rate risk related to forecasted transactions and the benchmark interest rate used is the on-the-run 10-year U.S. Treasury rate.

During the three months ended June 30, 2022, in connection with the 2032 Notes issuance, we settled four 10-year Treasury rate lock contracts totaling $600.0 million and received a settlement payment of $35.3 million (the "Treasury Lock Settlement"). As of June 30, 2022, the net accumulated gain is included in Accumulated other comprehensive income in our Consolidated Balance Sheets, and is being amortized as a reduction to interest expense on a straight-line basis over the 10-year term of the hedged transaction. We estimate that $3.5 million will be reclassified as a reduction to interest expense over the next 12 months. Following the Treasury Lock Settlement, we had no treasury lock contracts outstanding as of June 30, 2022. Refer to Note 19, "Subsequent Events," for information regarding interest rate derivative activity subsequent to June 30, 2022.

The following table presents the gross fair value amounts of our derivative financial instruments and the associated notional amounts (in millions):

Fair Value of Financial Instruments

Fair Value Disclosures [Abstract]

Fair Value Of Financial Instruments

Our financial instruments consist primarily of cash, cash equivalents and restricted cash, marketable securities, notes and other receivables, derivatives assets, debt, warrants and other liabilities. We utilize fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures, pursuant to ASC 820, "Fair Value Measurements and Disclosures." The following methods and assumptions were used in order to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value:

ASC 820, "Fair Value Measurements and Disclosures," requires disclosure regarding determination of fair value for assets and liabilities and establishes a hierarchy under which these assets and liabilities must be grouped, based on significant levels of observable or unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our market assumption. This hierarchy requires the use of observable market data when available. These two types of inputs have created the following fair value hierarchy:

Level 1 - Quoted unadjusted prices for identical instruments in active markets that we have the ability to access;

Level 2 - Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-derived valuations in which all significant inputs and significant value drivers are observable (e.g. interest rates, yield curves, prepayment speeds, default rates, loss severity, etc.) in active markets or can be corroborated by observable market data; and

Level 3 - Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. The unobservable inputs reflect our assumptions about the assumptions that market participants would use.

Assets by Hierarchy Level

The table below sets forth our financial assets and liabilities (in millions) that required disclosure of fair value on a recurring basis as of June 30, 2022. The table presents the carrying values and fair values of our financial instruments as of June 30, 2022 and December 31, 2021, that were measured using the valuation techniques described above. The table excludes other financial instruments such as other receivables and accounts payable as the carrying values associated with these instruments approximate their fair value since their maturities are less than one year. These are classified as Level 1 in the hierarchy.

We utilize fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The following methods and assumptions were used in order to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value:

Cash, Cash Equivalents and Restricted Cash

The carrying values of cash, cash equivalents and restricted cash approximate their fair market values due to the short-term nature of the instruments. These are classified as Level 1 in the hierarchy.

Marketable Securities

Marketable securities held by us and accounted for under ASC 321, "Investments - Equity Securities," are measured at fair value. Any change in fair value is recognized in the Consolidated Statement of Operations in the Gain / (loss) on remeasurement of marketable securities in accordance with ASU 2016-01, "Financial Instruments - Overall (Subtopic 825-10): Recognition and measurement of financial assets and financial liabilities." The fair value is measured by the quoted unadjusted share price which is readily available in active markets (Level 1).

The change in the marketable securities balance is as follows (in millions):

	Six Months Ended		Year Ended
	June 30, 2022		December 31, 2021
Beginning Balance	$	186.9	$	124.7
Additional purchases	—		35.5
Change in fair value measurement	(66.8)		33.4
Foreign currency translation adjustment	(7.0)		(9.2)
Dividend reinvestment, net of tax	1.5		2.5
Ending Balance	$	114.6	$	186.9

Installment Notes Receivable on Manufactured Homes

Installment notes receivable on manufactured homes are recorded at fair value and are measured using model-derived indicative pricing using primarily unobservable inputs, inclusive of default rates, interest rates and recovery rates (Level 3). Refer to Note 4, "Notes and Other Receivables," for additional information.

Notes Receivable from Real Estate Developers and Operators

Notes receivable from real estate developers and operators are recorded at fair value and are measured using model-derived indicative pricing using primarily unobservable inputs including interest rates and counterparty performance (Level 3). The carrying values of the notes generally approximate their fair market values either due to the nature of the note and / or the note being secured by underlying collateral and / or personal guarantees. Refer to Note 4, "Notes and Other Receivables," for additional information.

Derivative Assets - Interest Rate Derivatives

Interest rate derivatives are recorded at fair value and consist of Treasury locks. The fair value of the Treasury lock is measured using observable inputs based on the 10-year Treasury note rate (Level 2).

Secured Debt

Secured debt consists primarily of our mortgage term loans. The fair value of mortgage term loans is based on the estimates of management and on rates currently quoted, rates currently prevailing for comparable loans and instruments of comparable maturities (Level 2). Refer to Note 8, "Debt and Line of Credit," for additional information.

Unsecured Debt

Senior unsecured notes - the fair value of senior unsecured notes is based on the estimates of management and on rates currently quoted, rates currently prevailing for comparable loans and instruments of comparable maturities (Level 2). Refer to Note 8, "Debt and Line of Credit," for additional information.

Line of credit and other unsecured debt - consists primarily of our Senior Credit Facility. We have variable rates on our Senior Credit Facility. The fair value of the debt with variable rates approximates carrying value as the interest rates of these amounts approximate market rates. The estimated fair value of our indebtedness as of June 30, 2022 approximated its gross carrying value.

Other Financial Liabilities

We estimate the fair value of contingent consideration liabilities based on valuation models using significant unobservable inputs that generally consider discounting of future cash flows using market interest rates and adjusting for non-performance risk over the remaining term of the liability (Level 3).

Level 3 Reconciliation, Measurements and Transfers

We review the fair value hierarchy classifications each reporting period. Changes in the observability of the valuation attributes may result in a reclassification of certain financial assets or liabilities. Such reclassifications are reported as transfers in and out of Level 3 at the beginning fair value for the reporting period in which the changes occur. Availability of secondary market activity and consistency of pricing from third-party sources impacts our ability to classify securities as Level 2 or Level 3. There were no transfers into or out of Level 3 during the six months ended June 30, 2022.

The following table summarizes changes to our financial instruments carried at fair value and classified within Level 3 of the fair value hierarchy for the three and six months ended June 30, 2022 and 2021 (in millions):

Although we have determined the estimated fair value amounts using available market information and commonly accepted valuation methodologies, considerable judgment is required in interpreting market data to develop fair value estimates. The fair value estimates are based on information available as of June 30, 2022. As such, our estimates of fair value could differ significantly from the actual carrying value.

Failed sale leaseback

In connection with our acquisition of Park Holidays, we assumed ground lease arrangements for 25 UK properties that we concluded to be failed sale-leaseback transactions under ASC Topic 842, "Leases." The arrangements have maturities ranging from 2117 through 2143 with an option to repurchase for £1.00 at the end of the term. The obligation related to the underlying ground leases has been recorded as a financial liability of $287.5 million as of June 30, 2022.

Failed sale leaseback

In connection with our acquisition of Park Holidays, we assumed ground lease arrangements for 25 UK properties that we concluded to be failed sale-leaseback transactions under ASC Topic 842, "Leases." The arrangements have maturities ranging from 2117 through 2143 with an option to repurchase for £1.00 at the end of the term. The obligation related to the underlying ground leases has been recorded as a financial liability of $287.5 million as of June 30, 2022. The financial liability is recorded within Other Liabilities on the Consolidated Balance Sheets. The following table presents the future minimum rental payments for this financial liability as of June 30, 2022:

Accounting Changes and Error Corrections [Abstract]

Recent Accounting Pronouncements

Recent Accounting Pronouncements - Adopted

In August 2020, the FASB issued ASU 2020-06, "Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity's Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity's Own Equity." This update simplifies the accounting for convertible instruments by eliminating the models that require separation of a cash conversion or beneficial conversion feature from the host contract. Under the amended guidance, a convertible debt instrument is treated as one liability accounted for at its amortized cost and convertible preferred stock is considered one equity instrument accounted for at its historical cost, unless (a) there are other features that require bifurcation as a derivative, or (b) convertible debt was issued at a substantial premium. This update also eliminates several triggers for derivative accounting, including a requirement to settle certain contracts by delivering registered shares. Additionally, this update provides clarifications to improve the consistency of earnings per share (EPS) calculations. We adopted the ASU on January 1, 2022. The adoption of this ASU did not have an impact on our Consolidated Financial Statements.

Recent Accounting Pronouncements - Not Yet Adopted

In March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848) - Facilitation of the Effects of Reference Rate Reform on Financial Reporting," which provides optional guidance for accounting for contracts, hedging relationships and other transactions affected by the reference rate reform, if certain criteria are met. The provisions of this standard are available for election through December 31, 2022. As of June 30, 2022, we do not expect the transition from LIBOR to alternative reference interest rates will have a material impact on our Consolidated Financial Statements as the majority of our debt has fixed interest rates.

Subsequent Events [Abstract]

Subsequent Events

Acquisitions

Subsequent to the three months ended June 30, 2022, we acquired the following properties:

Property Name	Property Type	Sites, Wet Slips and Dry Storage Spaces	Development Sites	State, Province or Country	Total Purchase Price (in millions)
Gurney's Star Island Marina & Resort(1)	Marina	230	—	NY	$	190.0
Total Subsequent Acquisitions		230	—		$	190.0

(1) As part of the closing, we deposited funds into an escrow account. As of June 30, 2022, the deposit of $192.0 million is recorded within Other Assets on the Consolidated Balance Sheets.

Development Activity

Subsequent to the three months ended June 30, 2022, we acquired two land parcels located in the United States for an aggregate purchase price of $5.7 million.

Assets Held for Sale

We periodically classify real estate assets as held for sale. An asset is classified as held-for-sale after an active program to sell an asset has commenced and when the sale is probable. In July 2022, we identified two RV resorts in California comprised of 852 sites as held for sale, with total assets of $45.6 million and total liabilities of $13.0 million.

Equity Transactions

On July 5, 2022, we settled forward sale agreements with a total of 986,909 shares of common stock under our at the market offering program. The aggregate net proceeds from the settlement of the forward sale agreements was $180.7 million. We used the net proceeds to repay borrowings outstanding under our Senior Credit Facility.

On July 14, 2022, a third party elected to convert 922,000 Series I preferred OP units and 130,475 Common OP units into an aggregate of 692,670 shares of our common stock. After the conversion date, there were no Series I preferred OP units outstanding.

Derivative Transactions

On July 1, 2022, we entered into two treasury lock contracts with an aggregate notional value of $200.0 million to hedge interest rate risk associated with the future issuance of long-term fixed rate debt. The benchmark interest rate used is the on-the-run 10-year U.S. Treasury. We have designated these treasury lock contracts as cash flow hedges under ASC Topic 815, "Derivatives and Hedging." Accordingly, the unrealized gains or losses on the treasury lock contracts will be recorded within Accumulated Other Comprehensive Income on the Consolidated Balance Sheets and will be reclassified into earnings in the same period during which the hedged transaction affects earnings.

On July 20 and July 21, 2022, we entered into interest rate swap agreements to hedge variable rate borrowings of £400.0 million under the term loan on the Senior Credit Facility. The interest rate swaps lock in a total fixed rate, inclusive of spread, of 3.67 percent through the term loan maturity date of April 7, 2025.

We have evaluated our Consolidated Financial Statements for subsequent events through the date that this Form 10-Q was issued.
