Revenue Recognition Policies and Performance Obligations

On January 1, 2018, we adopted FASB Accounting Standards Update (“ASU”) 2014-09 “Revenue from Contracts with Customers” and the other related ASUs and amendments to the codification (collectively “ASC 606”). The core principle of ASC 606 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. A five-step transactional analysis is required to determine how and when to recognize revenue. ASC 606 applies to all contracts with customers, except those that are within the scope of other topics in the FASB accounting standards codification.

As a real estate owner and operator, the majority of our revenue is derived from site and home leases that are accounted for pursuant to ASC 840 “Leases.” For transactions in the scope of ASC 606, we recognize revenue when control of goods or services transfers to the customer, in the amount that we expect to receive for the transfer of goods or provision of services. The adoption of ASC 606 did not result in any change to our accounting policies for revenue recognition. Accordingly, retrospective application to prior periods or a cumulative catch-up adjustment was unnecessary.

Income from real property - Residents in our communities lease the site on which their home is located, and either own or lease their home. Lease revenues for sites and homes fall under the scope of ASC 840, and are accounted for as operating leases with straight-line recognition. Resident leases are generally for one-year or month-to-month terms, and are renewable by mutual agreement from us and the resident, or in some cases, as provided by jurisdictional statute. Non-lease components of our site lease contracts, which are primarily provision of utility services, are accounted for with the site lease as a single lease under ASC 840. Additionally, we include collections of real estate taxes from residents within Income from real property.

Revenue from home sales - Our taxable REIT subsidiary, SHS, sells manufactured homes (“MH”) to current and prospective residents in our communities. Prior to adoption of ASC 606, we recognized revenue for home sales pursuant to ASC 605 “Revenue Recognition,” as manufactured homes are tangible personal property that can be located on any land parcel. Manufactured homes are not permanent fixtures or improvements to the underlying real estate, and were therefore not considered to be subject to the guidance in ASC 360-20 “Real Estate Sales” by the Company. In accordance with the core principle of ASC 606, we recognize revenue from home sales at the time of closing when control of the home transfers to the customer. After closing of the sale transaction, we have no remaining performance obligation.

Rental home revenue - is comprised of rental agreements whereby we lease homes to residents in our communities. We account for these revenues under ASC 840.

Ancillary revenues - are primarily composed of proceeds from restaurant, golf, merchandise and other activities at our recreational vehicle (“RV”) communities. Revenues are recognized at point of sale when control of the good or service transfers to the customer and our performance obligation is satisfied. Sales and other taxes that we collect concurrent with revenue-producing activities are excluded from transaction price.

Interest income - is earned primarily on our notes and collateralized receivables, which includes installment loans for manufactured homes purchased by the Company from loan originators and transferred loans that previously did not meet the requirements for sale accounting. Interest income on these receivables is accrued based on the unpaid principal balances of the underlying loans on a level yield basis over the life of the loans. Interest income is not in the scope of ASC 606. Refer to Notes 4, “Collateralized Receivables and Transfers of Financial Assets” and 5, “Notes and Other Receivables” for additional information.

7

Broker commissions and other revenues, net - is primarily comprised of brokerage commissions for sales of manufactured homes, where we act as agent and arrange for a third-party to transfer a manufactured home to a customer within one of our communities. Brokerage commission revenues are recognized on a net basis at closing, when the transaction is completed and our performance obligations have been fulfilled. Loan loss reserve expenses for our collateralized receivables and notes receivables are also included herein. Refer to Notes 4, “Collateralized Receivables and Transfers of Financial Assets” and 5, “Notes and Other Receivables” for additional information regarding our loan loss reserves.

Contract Balances

As of June 30, 2018 and December 31, 2017, we had $18.2 million and $13.8 million, respectively, of receivables from contracts with customers. Receivables from contracts with customers are presented as a component of Notes and other receivables on our Consolidated Balance Sheets. These receivables represent balances owed to us for previously completed performance obligations for sales of manufactured homes. Due to the nature of our revenue from contacts with customers, we do not have material contract assets or liabilities that fall under the scope of ASC 606.

3.      Real Estate Acquisitions

2018 Acquisitions

Dispositions

There were no property dispositions during the six months ended June 30, 2018 or the year ended December 31, 2017.

4.      Collateralized Receivables and Transfers of Financial Assets

We previously completed various transactions with an unrelated entity involving our notes receivable under which we received cash proceeds in exchange for relinquishing our right, title, and interest in certain notes receivable. We have no further obligations or rights with respect to the control, management, administration, servicing, or collection of the installment notes receivable. However, we are subject to certain recourse provisions requiring us to purchase the underlying homes collateralizing such notes, in the event of a note default and subsequent repossession of the home by the unrelated entity. The recourse provisions are considered to be a form of continuing involvement, and therefore these transferred loans did not meet the requirements for sale accounting. We continue to recognize these transferred loans on our balance sheet and refer to them as collateralized receivables. The proceeds from the transfer have been recognized as a secured borrowing.

In the event of a note default and subsequent repossession of a manufactured home by the unrelated entity, the terms of the agreement require us to repurchase the manufactured home. Default is defined as the failure to repay the installment note receivable according to contractual terms. The repurchase price is calculated as a percentage of the outstanding principal balance of the collateralized receivable, plus any outstanding late fees, accrued interest, legal fees, and escrow advances associated with the installment note receivable. The percentage used to determine the repurchase price of the outstanding principal balance on the installment note receivable is based on the number of payments made on the note. In general, the repurchase price is determined as follows:

Number of Payments	Repurchase Percentage
Fewer than or equal to 15	100	%
Greater than 15 but fewer than 64	90	%
Equal to or greater than 64 but fewer than 120	65	%
120 or more	50	%

The transferred assets have been classified as Collateralized receivables, net and the cash proceeds received from these transactions have been classified as Secured borrowings on collateralized receivables within the Consolidated Balance Sheets. The balance of the collateralized receivables was $117.3 million (net of allowance of $0.9 million) and $128.2 million (net of allowance of $0.9 million) as of June 30, 2018 and December 31, 2017, respectively. The receivables have a weighted average interest rate and maturity of 10.0 percent and 14.5 years as of June 30, 2018, and 10.0 percent and 15.3 years as of December 31, 2017.

The outstanding balance on the secured borrowing was $118.2 million and $129.2 million as of June 30, 2018 and December 31, 2017, respectively.

The collateralized receivables earn interest income, and the secured borrowings accrue interest expense at the same interest rates. The amount of interest income and expense recognized was $2.9 million and $3.3 million for the three months ended June 30, 2018 and 2017, respectively, and $5.7 million and $6.6 million for the six months ended June 30, 2018 and 2017, respectively.

The balances of the collateralized receivables and secured borrowings are reduced as the related collateralized receivables are collected from the customers, or as the underlying collateral is repurchased. The change in the aggregate gross principal balance of the collateralized receivables is as follows (in thousands):

	Six Months Ended   June 30, 2018

6. Intangible Assets

Our intangible assets include ground leases, in-place leases, franchise fees and other intangible assets. These intangible assets are recorded in Other assets, net on the Consolidated Balance Sheets.

During the three months ended June 30, 2018, we acquired 50 percent of a land parcel that was previously subject to a ground lease at one of our California communities for $8.0 million. As a result of the transaction, we wrote off $1.1 million of the gross carrying amount of the ground lease intangible and $0.3 million of the related accumulated amortization. The $0.8 million net write off is included within the Property operating and maintenance expenses in our Consolidated Statements of Operations for the three months ended June 30, 2018.

7.      Investment in Affiliates

GTSC LLC (“GTSC”)

In February 2018, the Company became a noncontrolling member of GTSC. GTSC engages in acquiring, holding and selling loans secured, directly or indirectly, by manufactured homes located in communities of Sun Communities. At June 30, 2018, we had a 40 percent ownership interest in GTSC. The remaining 60 percent interest is owned by an unrelated third-party. We account for our interest in GTSC under the equity method of accounting as prescribed by ASC 323 “Investments - Equity Method and Joint Ventures.” Based on the power and economics criteria under the variable interest entity (“VIE”) model in ASC 810, we are not the primary beneficiary of GTSC. During the six months ended June 30, 2018, there was $0.1 million net loss in Brokerage commissions and other revenues, net on the Consolidated Statement of Operations related to our ownership interest. Our investment in GTSC as of June 30, 2018, is $9.2 million and recorded within Other assets, net on the Consolidated Balance Sheet.

8.      Consolidated Variable Interest Entities

Effective June 1, 2018, we acquired an 80 percent equity interest in Sun NG Resorts, consisting of 10 operating RV resorts and one RV ground up development. We consolidate Sun NG Resorts under the guidance set forth in FASB ASC Topic 810 “Consolidation.” We concluded that Sun NG Resorts is a variable interest entity where we are the primary beneficiary, as we have power to direct the significant activities, absorb the significant losses and receive the significant benefits from the entity. Refer to Note 3, “Real Estate Acquisitions,” Note 9, “Debt and Lines of Credit,” and Note 10, “Equity and Mezzanine Securities” for additional information.

We consolidate Rudgate Village SPE, LLC; Rudgate Clinton SPE, LLC; and Rudgate Clinton Estates SPE, LLC (collectively, “Rudgate”) as a VIE. We evaluated our arrangement with this property under the guidance set forth in FASB ASC Topic 810 “Consolidation.” We concluded that Rudgate qualified as a VIE where we are the primary beneficiary, as we have power to direct the significant activities, absorb the significant losses and receive the significant benefits from the entity.

Preferred OP Units

Preferred OP units at June 30, 2018 and December 31, 2017 include $34.7 million of Aspen preferred OP units issued by the Operating Partnership. As of June 30, 2018, these units are convertible indirectly into 453,281 shares of our common stock. Subject to certain limitations, at any time prior to January 1, 2024, the holder of each Aspen preferred OP unit at its option may convert such Aspen preferred OP unit into: (a) if the market price of our common stock is $68.00 per share or less, 0.397 common OP units; or (b) if the market price of our common stock 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 percent of the amount by which the market price of our common stock exceeds $68.00 per share, by (ii) the per-share market price of our common stock. The current preferred distribution rate is 6.5 percent. On January 2, 2024, we are required to redeem all Aspen preferred OP units that have not been converted to common OP units.

Preferred OP units also include $2.7 million and $6.7 million at June 30, 2018 and December 31, 2017, respectively, of Series B-3 preferred OP units, which are not convertible.

In the aggregate, we paid $4.1 million to redeem these units.

Subject to certain limitations, (a) during the 90-day period beginning on each of the tenth through fifteenth anniversaries of the issue date of the applicable Series B-3 preferred OP units, (b) at any time after the fifteenth anniversary of the issue date of the applicable Series B-3 preferred OP units, or (c) after our receipt of notice of the death of the electing holder of a Series B-3 preferred OP unit, each holder of Series B-3 preferred OP units may require us to redeem such holder's Series B-3 preferred OP units at the redemption price of $100.00 per unit. In addition, at any time after the fifteenth anniversary of the issue date of the applicable Series B-3 preferred OP units we may redeem, at our option, all of the Series B-3 preferred OP units of any holder thereof at the redemption price of $100.00 per unit.

In June 2018, in connection with the investment in Sun NG Resorts, $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 and can be redeemed in the fourth quarter of 2022 at the holders’ option. The Preferred Equity - Sun NG Resorts as of June 30, 2018 was $35.3 million. Refer to Note 3, “Real Estate Acquisitions,” Note 8, “Consolidated Variable Interest Entities,” and Note 10, “Equity and Mezzanine Securities” for additional information.

Lines of Credit

In April 2017, we amended and restated our credit agreement (the “A&R Credit Agreement”) with Citibank, N.A. (“Citibank”) and certain other lenders. Pursuant to the A&R Credit Agreement, we have a senior revolving credit facility with Citibank and certain other lenders in the amount of $650.0 million, comprised of a $550.0 million revolving loan and a $100.0 million term loan (the “A&R Facility”). The A&R Credit Agreement has a four-year term ending April 25, 2021, which can be extended for two additional six-month periods at our option, subject to the satisfaction of certain conditions as defined in the credit agreement. The A&R Credit Agreement also provides for, subject to the satisfaction of certain conditions, additional commitments in an amount not to exceed $350.0 million. If additional borrowings are made pursuant to any such additional commitments, the aggregate borrowing limit under the A&R Facility may be increased up to $1.0 billion.

The A&R Facility bears interest at a floating rate based on the Eurodollar rate plus a margin that is determined based on our leverage ratio calculated in accordance with the A&R Credit Agreement, which margin can range from 1.35 percent to 2.20 percent for the revolving loan and 1.30 percent to 2.15 percent for the term loan. As of June 30, 2018, the margin based on our leverage ratio was 1.35 percent and 1.30 percent on the revolving and term loans, respectively. We had $434.0 million in borrowings on the revolving loan and $100.0 million in borrowings on the term loan, totaling $534.0 million as of June 30, 2018, with a weighted average interest rate of 3.33 percent.

The A&R Facility replaced our $450.0 million credit facility (the “Previous Facility”), which was scheduled to mature on August 19, 2019. The A&R Facility provides, and the Previous Facility provided, us with the ability to issue letters of credit. Our issuance of letters of credit does not increase our borrowings outstanding under our line of credit, but does reduce the borrowing amount available. At June 30, 2018 and December 31, 2017, approximately $1.9 million and $1.3 million, respectively, of availability was used to back standby letters of credit.

We have a $12.0 million manufactured home floor plan facility renewable indefinitely until our lender provides us at least a twelve month notice of their intent to terminate the agreement. The interest rate is 100 basis points over the greater of the prime rate as quoted in the Wall Street Journal on the first business day of each month or 6.0 percent. At June 30, 2018, the effective interest rate was 7.0 percent. The outstanding balance was $2.8 million as of June 30, 2018 and $4.0 million as of December 31, 2017.

Covenants

Pursuant to the terms of the A&R Facility, we are subject to various financial and other covenants. The most restrictive of our debt agreements place limitations on secured borrowings and contain minimum fixed charge coverage, leverage, distribution, and net worth requirements. At June 30, 2018, 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 the debts and other obligations of the Company, any of its other subsidiaries or any other person or entity.

10.      Equity and Mezzanine Securities

Public Equity Offerings

In May 2017, we closed an underwritten registered public offering of 4,830,000 shares of common stock at a gross price of $86.00 per share. Proceeds from the offering were $408.9 million after deducting expenses related to the offering, which were used to repay borrowings outstanding under the revolving loan under our A&R Facility, fund acquisitions, working capital and general corporate purposes.

At the Market Offering Sales Agreement

In July 2017, we entered into a new at the market offering sales agreement (the “Sales Agreement”) with BMO Capital Markets Corp., Merrill Lynch, Pierce, Fenner & Smith Incorporated, Citigroup Global Markets Inc., Robert W. Baird & Co. Incorporated, Fifth Third Securities, Inc., RBC Capital Markets, LLC, BTIG, LLC, Jefferies LLC, Credit Suisse Securities (USA) LLC and Samuel A. Ramirez & Company, Inc. (each, a “Sales Agent;” collectively, the “Sales Agents”), whereby we may offer and sell shares of our common stock, having an aggregate offering price of up to $450.0 million, from time to time through the Sales Agents. The Sales Agents are entitled to compensation in an agreed amount not to exceed 2.0 percent of the gross price per share for any shares sold from time to time under the Sales Agreement. Through June 30, 2018, we have sold shares of our common stock for gross proceeds of $123.8 million under the Sales Agreement.

Issuances of common stock under the Sales Agreement during 2018 were as follows:

Year to Date	Common Stock Issued	Weighted Average Sales Price		Net Proceeds (in Millions)
June 30, 2018	1,008,699	$	92.98	$	92.6

Refer to Note 18, “Subsequent Events” for additional information regarding issuances of common stock activity after June 30, 2018.

Equity Interests - 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 interest (herein jointly referred to as “Equity Interest - NG Sun LLC”). 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 Interests - NG Sun LLC do not

Series A-4 Preferred Stock	6/18/2018	7/2/2018	$	0.40625	$	432

Redemptions

If certain change of control transactions occur or if our common stock ceases to be listed or quoted on an exchange or quotation system, then at any time after November 26, 2019, we or the holders of shares of Series A-4 preferred stock and Series A-4 preferred OP units may cause all or any of those shares or units to be redeemed for cash at a redemption price equal to the sum of (i) the greater of (x) the amount that the redeemed shares of Series A-4 preferred stock and Series A-4 preferred OP units would have received in such transaction if they had been converted into shares of our common stock immediately prior to such transaction, or (y) $25.00 per share, plus (ii) any accrued and unpaid distributions thereon to, but not including, the redemption date.

In November 2017, we redeemed all of the outstanding shares of our 7.125% Series A Cumulative Redeemable Preferred Stock. Holders received a cash payment of $25.14349 per share which included accrued and unpaid dividends. In the aggregate, we paid $85.5 million to redeem all of the 3,400,000 outstanding shares.

In June 2017, we redeemed 438,448 shares of Series A-4 Preferred Stock and 200,000 shares of Series A-4 preferred OP units from Green Courte Real Estate Partners III, LLC, GCP Fund III REIT LLC and GCP Fund III Ancillary Holding, LLC (collectively, the “Green Courte Entities”) for total consideration of $24.7 million. Accrued dividends totaling $0.2 million were also paid in connection with the redemptions. The Green Courte Entities were the sellers of the American Land Lease portfolio which we acquired in 2014 and 2015.

Repurchase Program

SUN COMMUNITIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

In November 2004, our Board of Directors authorized us to repurchase up to 1,000,000 shares of our common stock. We have 400,000 common shares remaining in the repurchase program. No common shares were repurchased during the six months ended June 30, 2018 or 2017. There is no expiration date specified for the buyback program.

11.      Share-Based Compensation

As of June 30, 2018, we had two share-based compensation plans; the Sun Communities, Inc. 2015 Equity Incentive Plan (“2015 Equity Incentive Plan”) and the First Amended and Restated 2004 Non-Employee Director Option Plan (“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.

The following table shows details on grants of equity awards during the six months ended June 30, 2018:

Grant Period	Type	Plan	Shares Granted	Grant Date Fair Value Per Share			Vesting Type	Vesting Anniversary	Percentage
2018	Key Employees	2015 Equity Incentive Plan	16,500	$	88.30	(1)	Time Based	2nd	35.0	%
								3rd	35.0	%
								4th	20.0	%
								5th	5.0	%
								6th	5.0	%
2018	Key Employees	2015 Equity Incentive Plan	44,600	$	85.29	(1)	Time Based	20.0% annually over 5 years
2018	Executive Officers	2015 Equity Incentive Plan	60,000	$	87.24	(1)	Time Based	20.0% annually over 5 years
2018	Executive Officers	2015 Equity Incentive Plan	90,000	$	65.24	(2)	Market Condition	3rd	100.0	%
2018	Directors	2004 Non-Employee Director Option Plan	16,800	$	85.28	(1)	Time Based	3rd	100.0	%

⁽¹⁾ The fair value of the grants were determined by using the closing price of our common stock on the dates the shares were issued.

⁽²⁾ Share-based compensation for restricted stock awards with market conditions is measured based on an estimate of shares expected to vest. We estimate the fair value of share-based compensation for restricted stock with market conditions using a Monte Carlo simulation. At the grant date our common stock price was $87.24. Based on the Monte Carlo simulation we expect 74.8% of the 90,000 shares to vest.

Vesting

The vesting requirements for 173,993 restricted shares granted to our executives, directors and employees were satisfied during the six months ended June 30, 2018.

12. Segment Reporting

We group our operating segments into reportable segments that provide similar products and services. Each operating segment has discrete financial information evaluated regularly by our chief operating decision maker in evaluating and assessing performance. We have two reportable segments: (i) Real Property Operations and (ii) Home Sales and Rentals. The Real Property Operations segment owns, operates, develops, or has an interest in a portfolio of MH and RV communities, and is in the business of acquiring, operating, and expanding MH and RV communities. The Home Sales and Rentals segment offers MH and RV park model sales and leasing services to tenants and prospective tenants of our communities.

Transactions between our segments are eliminated in consolidation. Transient RV revenue is included in the Real Property Operations segment revenues and is expected to approximate $106.5 million annually. This transient RV revenue was recognized 20.7 percent and 20.3 percent in the first and second quarters, respectively, and is expected to be recognized at 41.9 percent and 17.1 percent in the third and fourth quarters, respectively. Transient revenue was $78.0 million for the year ended December 31, 2017. We recognized 27.2 percent in the first quarter, 20.1 percent in the second quarter, 36.9 percent in the third quarter, and 15.8 percent in the fourth quarter.

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

13.    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 stockholders 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 quarter ended June 30, 2018.

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 stockholders 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 (including any applicable alternative minimum tax). 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. The Company is also subject to local income taxes in Canada as a result of the acquisition of Carefree in 2016. 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.

Our taxable REIT subsidiaries are subject to U.S. federal income taxes as well as state and local income and franchise taxes. In addition, our Canadian subsidiaries are subject to income tax in Canada.

Deferred tax assets and liabilities reflect the impact of temporary differences between the amounts of assets and liabilities for financial reporting purposes and the bases 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 U.S. GAAP on our Canadian investments. Generally, full valuation allowances are recorded against almost all U.S. federal deferred tax assets. Deferred tax liabilities of $21.7 million for Canadian entities have been recorded in relation to corporate entities and included in “Other liabilities” in our Consolidated Balance Sheets as of June 30, 2018. There were no U.S. federal deferred tax assets or liabilities included in our Consolidated Balance sheets as of December 31, 2017.

We had no unrecognized tax benefits as of June 30, 2018 and 2017. We do not expect significant changes in tax positions that would result in unrecognized tax benefits within one year of June 30, 2018.

We recorded a current tax expense for federal, state, and Canadian income taxes of approximately $0.2 million for the three months ended June 30, 2018 and a current tax benefit of $7 thousand for the three months ended June 30, 2017. For the six months ended June 30, 2018 and 2017, we recorded a current tax expense of $0.4 million and $0.2 million, respectively.

We recorded $0.1 million of deferred tax expense on our Consolidated Statements of Operations for the three months ended June 30, 2018 and recorded a deferred tax benefit of $0.4 million for the three months ended June 30, 2017. For the six months ended June 30, 2018 and 2017, we recorded a deferred tax benefit of $0.2 million and $0.7 million, respectively.

In 2017, SHS underwent an audit by the Internal Revenue Service for the 2015 tax year. Upon conclusion of the audit in 2018, no adjustment was required.

15.    Fair Value of Financial Instruments

Our financial instruments consist primarily of cash and cash equivalents, accounts and notes receivable, accounts payable, derivative instruments, and debt.

ASC Topic 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 the Company’s 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;

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 in active markets; and

Level 3—Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

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:

Installment Notes Receivable on Manufactured Homes

The net carrying value of the installment notes receivable on manufactured homes estimates the fair value as the interest rates in the portfolio are comparable to current prevailing market rates (Level 2). Refer to Note 5, “Notes and Other Receivables.”

Long-Term Debt and Lines of Credit

The fair value of long-term debt (excluding the secured borrowing) 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 9, “Debt and Lines of Credit.”

Collateralized Receivables and Secured Borrowings

The fair value of these financial instruments offset each other as our collateralized receivables represent a transfer of financial assets and the cash proceeds received from these transactions have been classified as a secured borrowing on the Consolidated Balance Sheets. The net carrying value of the collateralized receivables estimates the fair value as the interest rates in the portfolio are comparable to current prevailing market rates (Level 2). Refer to Note 4, “Collateralized Receivables and Transfers of Financial Assets.”

Financial Liabilities

We estimate the fair value of our contingent consideration liability based on discounting of future cash flows using market interest rates and adjusting for non-performance risk over the remaining term of the liability (Level 2).

Other Financial Instruments

The carrying values of cash and cash equivalents, accounts receivable, and accounts payable approximate their fair market values due to the short-term nature of these instruments.

16.    Recent Accounting Pronouncements

Recent Accounting Pronouncements - Adopted

On January 1, 2018, we adopted ASU 2014-09 “Revenue from Contracts with Customers (Topic 606).” Refer to Note 2, “Revenue” for information regarding our adoption of this guidance.

On January 1, 2018 we adopted ASU 2017-09 “Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting.” This update provided clarity and reduced both diversity in practice and cost and complexity when applying the guidance in Topic 718, Compensation - Stock Compensation, regarding a change to the terms or conditions of a share-based payment award. There was no initial impact that resulted from adoption of this guidance; it will be applied should a modification occur.

On January 1, 2018, we adopted ASU 2017-01 “Business Combinations (Topic 805): Clarifying the Definition of a Business.” This update clarified the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The definition of a business affects many areas of accounting including acquisitions, disposals, goodwill, and consolidation.

Under previous guidance, substantially all of our property acquisitions were accounted for as business combinations with identifiable assets and liabilities measured at fair value, and acquisition related costs expensed as incurred and reported as Transaction costs in our Consolidations Statements of Operations.

With the adoption of ASU 2017-01, we expect that substantially all of our future property acquisitions will be accounted for as asset acquisitions. We allocate the purchase price of these properties on a relative fair value basis and capitalize direct acquisition related costs as part of the purchase price. Acquisitions costs that do not meet the criteria to be capitalized will be expensed as incurred and presented as General and administrative costs in our Consolidated Statements of Operations.

On January 1, 2018, we adopted ASU 2016-18 “Statement of Cash Flows (Topic 230): Restricted Cash.” This update required inclusion of restricted cash and restricted cash equivalents with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows.

Our restricted cash consists of amounts primarily held in deposit for tax, insurance and repair escrows held by lenders in accordance with certain debt agreements. Restricted cash is included as a component of Other assets, net on the Consolidated Balance Sheets. Changes in restricted cash are reported in our Consolidated Statements of Cash Flows as operating, investing or financing activities based on the nature of the underlying activity.

The following table reconciles our beginning-of-period and end-of-period balances of cash, cash equivalents and restricted cash for the periods shown (in thousands):

Recent Accounting Pronouncements - Not Yet Adopted

In June 2016, the FASB issued ASU 2016-13 “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” This update replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The amendments in this update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. We are in the initial phases of evaluating how this guidance will impact our accounting policies regarding assessment of, and allowance for, loan losses.

In February 2016, the FASB issued ASU 2016-02 “Leases (Topic 842).” The core principle of this update is that a lessee should recognize the assets and liabilities that arise from leases while the accounting by a lessor is largely unchanged from that applied under previous GAAP. The amendments in this update are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Our income from real property and rental home revenue streams is derived from rental agreements where we are the lessor. As noted above, the lessor accounting model is largely unchanged by this update. We are the lessee in other arrangements, primarily for our executive offices, ground leases at certain communities and certain equipment. We are currently evaluating our inventory of such leases to determine which will require recognition of right of use assets and corresponding lease liabilities, and the related disclosure requirements thereto.

17.   Commitments and Contingencies

Legal Proceedings

We are involved in various legal proceedings arising in the ordinary course of business. All such proceedings, taken together, are not expected to have a material adverse impact on our results of operations or financial condition.

Catastrophic Weather Related Estimates

In September 2017, our communities in Florida and Georgia sustained damages from Hurricane Irma. The table below sets forth estimated losses (in millions). Future changes to estimated losses will be recognized in the period(s) in which they are determined.

We maintain property, casualty, flood and business interruption insurance for our community portfolio, subject to customary deductibles and limits. The table below sets forth estimated insurance recoveries (in millions). Actual insurance recoveries could vary significantly from our estimates. Future changes to estimated insurance recoveries will be recognized in the period(s) in which they are determined.

	Six Months Ended June 30, 2018
Total estimated insurance receivable - December 31, 2017	$	23.7
Change in estimated insurance recoveries	7.8
Advances from insurer	(9.4		)
Total estimated insurance receivable - June 30, 2018	$	22.1

Changes in estimated insurance recoveries for damages during the six months ended June 30, 2018, were primarily the result of incremental invoices for which the total costs exceeded the applicable deductible. The change in estimated losses and changes in estimated insurance recoveries during the three and six months ended June 30, 2018, resulted in a net loss of $0.1 million and a net gain of $2.2 million, respectively to Catastrophic weather related charges, net in our Consolidated Statements of Operations.

We are actively working with our insurer on claims for lost earnings and redevelopment costs greater than the asset impairment charge for the three Florida Keys communities. The three impaired Florida Keys communities will require redevelopment followed by a tenant lease-up period. As such, we currently cannot estimate a date when operating results will be restored to pre-hurricane levels. Our business interruption insurance policy provides for up to 60 months of coverage from the date of restoration.

18.   Subsequent Events

In July 2018, we issued 193,001 shares of common stock through our At-the-Market equity sales program at a weighted average price of $97.93 per share. Net proceeds from the sales were $18.7 million.

In July 2018, we acquired The Sands RV & Golf Resort (“The Sands”) for $14.3 million, an RV resort that contains 507 RV sites and is located in Desert Hot Springs, California.

In July 2018, the Company entered into a $228.0 million collateralized term loan with a 4.10 percent fixed rate and a 20 year term.

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 Notes filed herewith, along with our 2017 Annual Report. Capitalized terms are used as defined elsewhere in this Quarterly Report on Form 10-Q.

OVERVIEW

We are a fully integrated, self-administered and self-managed REIT. As of June 30, 2018, we owned and operated or held an interest in a portfolio of 367 developed properties located in 31 states throughout the U.S. and one province in Canada, including 230 MH communities, 106 RV communities, and 31 properties containing both MH and RV sites.

We have been in the business of acquiring, operating, developing, and expanding MH and RV communities since 1975. We lease individual sites with utility access for placement of manufactured homes and RVs to our customers. We are also engaged through SHS in the marketing, selling, and leasing of new and pre-owned homes to current and future residents in our communities. The operations of SHS 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 2017 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 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, 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

28

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. Further, 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.

29

RESULTS OF OPERATIONS

We report operating results under two segments: Real Property Operations and Home Sales and Rentals. The Real Property Operations segment owns, operates, develops, or has an interest in, a portfolio of MH and RV communities throughout the U.S. and in Canada, and is in the business of acquiring, operating, and expanding MH and RV communities. The Home Sales and Rentals segment offers MH and RV park model sales and leasing services to tenants and prospective tenants of our communities. We evaluate segment operating performance based on NOI and gross profit. Refer to Note 12, “Segment Reporting,” in our accompanying Consolidated Financial Statements for additional information.

REAL PROPERTY OPERATIONS – SAME COMMUNITIES

A key management tool used when evaluating performance and growth of our properties is a comparison of our Same Communities. Same Communities consist of stabilized properties owned and operated since January 1, 2017. The Same Community 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 Communities, management has classified certain items differently than our GAAP statements, primarily the reclassification of water and sewer revenues from Income from real property to Utilities. A significant portion of our utility charges are re-billed to our residents. We have reclassified $7.8 million and $7.5 million for the three months ended June 30, 2018 and 2017, respectively, to reflect the utility expenses associated with our Same Community portfolio net of recovery.

The following tables reflect certain financial and other information for our Same Communities as of and for the three months ended June 30, 2018 and 2017. The amounts in the table below reflect constant currency for comparative purposes. Canadian currency figures included within the three months ended June 30, 2017 have been translated at 2018 exchange rates:

⁽¹⁾  The occupancy percentage includes MH and annual RV sites, and excludes recently completed but vacant expansion sites and transient RV sites.

⁽²⁾ The occupancy percentage for 2017 has been adjusted to reflect incremental growth period-over-period from filled MH expansion sites and the conversion of transient RV sites to annual RV sites.

⁽³⁾  Monthly base rent pertains to annual RV sites and excludes transient RV sites.

Real property NOI growth of 7.2 percent is primarily due to increased Income from real property of $10.8 million, or 6.3 percent. The 6.3 percent increase is primarily attributable to a 2.0 percent increase in occupancy and a 4.0 percent increase in total monthly base rent per site during the three months ended June 30, 2018. The increase in Income from real property was partially offset by a $2.6 million, or 4.6 percent, increase in Property operating expenses, primarily attributable to increases in utilities, real estate taxes, payroll and benefits and other expenses.

Rental program NOI increased 3.7 percent due to an increase in revenues of 4.2 percent, or $1.2 million, partially offset by an increase in operating and maintenance expenses of 6.6 percent, or $0.3 million. The increase in revenues is attributable to a 4.3 percent increase in the weighted average monthly rental rate partially offset by a slight decrease in the number of occupied rentals. The $0.3 million increase in operating and maintenance expenses is primarily the result of increased commissions and marketing expenses partially offset by a decrease in repairs and refurbishment expense in the three months ended June 30, 2018, as compared to the same period in 2017.

Real property NOI growth of 6.2 percent is primarily due to increased Income from real property of $20.7 million, or 6.0 percent. The 6.0 percent increase is attributable to the 2.0 percent increase in occupancy and a 4.0 percent increase in total monthly base rent per site. This increase was partially offset by a $6.0 million, or 5.6 percent, increase in Property operating expenses, primarily attributable to increases in utilities, legal, taxes, and insurance, real estate taxes and other expenses.

For purposes of management analysis, the site rent is included in the Rental Program revenue to evaluate the incremental revenue gains associated with implementation of the Rental Program, and assess the overall growth and performance of the Rental Program and financial impact to our operations.

Rental program NOI increased 4.5 percent due to an increase in revenues of 4.4 percent, or $2.5 million, partially offset by an increase in operating and maintenance expenses of 3.9 percent, or $0.4 million. The increase in revenues is partially attributable to a 4.3 percent increase in the weighted average monthly rental rate partially offset by a slight decrease in the number of occupied rentals. The increase in operating and maintenance expenses of $0.4 million is primarily the result of increased marketing costs and taxes and insurance, partially offset by decreased repairs and refurbishment expenses in the six months ended June 30, 2018 as compared to the same period in 2017.

⁽²⁾  In January 2018, we adopted ASU 2017-01, which clarified the definition of a business with the objective of assisting entities in evaluating whether transactions should be accounted for as acquisitions of assets or businesses. Under previous guidance, substantially all of our property acquisitions were accounted for as business combinations with identifiable assets and liabilities measured at fair value, and acquisition related costs expensed as incurred and reported as Transaction costs. Under the new guidance, we expect that substantially all of our future property acquisitions will be accounted for as asset acquisitions. The purchase price of these properties are allocated on a relative fair value basis and capitalize direct acquisition related costs as part of the purchase price. Acquisitions costs that do not meet the criteria for capitalization will be expensed as incurred and reported as General and administrative costs.

43

⁽³⁾  These costs represent the expenses incurred to bring recently acquired properties up to our operating standards, including items such as tree trimming and painting costs that do not meet our capitalization policy.

⁽⁴⁾  Adjustment represents estimated loss of earnings in excess of the applicable business interruption deductible in relation to our three Florida Keys communities that were impaired by Hurricane Irma. We are actively working with our insurer on the related claims, but have not yet received any advance for the expected recovery of lost earnings.

LIQUIDITY AND CAPITAL RESOURCES

Our principal liquidity demands have historically been, and are expected to continue to be, distributions to our stockholders and the unit holders of the Operating Partnership, capital improvement of properties, the purchase of new and pre-owned homes, property acquisitions, development and expansion of properties, and debt repayment.

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

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 intend to meet our liquidity requirements through available cash balances, cash flows generated from operations, draws on our lines of credit, and the use of debt and equity offerings under our shelf registration statement. Refer to Note 9, “Debt and Lines of Credit” and Note 10, “Equity and Mezzanine Securities” in our accompanying Consolidated Financial Statements for additional information.

Our capital expenditures include expansion and development, lot modifications, recurring capital expenditures and rental home purchases. For the six months ended June 30, 2018 and 2017, expansion and development activities of $61.3 million and $32.5 million, respectively, related to costs consisting primarily of construction of sites and other costs necessary to complete home site improvements.

For the six months ended June 30, 2018 and 2017, lot modification expenditures were $9.5 million and $10.7 million, respectively. These expenditures improve asset quality in our communities and are incurred when an existing home is removed and the site is prepared for a new home (more often than not, a multi-sectional home). These activities, which are mandated by strict manufacturer’s installation requirements and state building codes, include items such as new foundations, driveways, and utility upgrades.

For the six months ended June 30, 2018 and 2017, recurring capital expenditures of $7.1 million and $8.4 million, respectively, related to our continued commitment to the upkeep of our properties.

We invest in the acquisition of homes intended for the Rental Program. Expenditures for these investments depend upon the condition of the markets for repossessions and new home sales, as well as rental homes. We finance new home purchases with a $12.0 million manufactured home floor plan facility. Our ability to purchase homes for sale or rent may be limited by cash received from third-party financing of our home sales, available manufactured home floor plan financing and working capital available on our lines of credit.

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

	Six Months Ended June 30,
	2018			2017
Net Cash Provided by Operating Activities	$	198,682		$	156,626
Net Cash Used for Investing Activities	$	(407,491	)	$	(167,126	)
Net Cash Provided by Financing Activities	$	222,353		$	247,334
Effect of Exchange Rate Changes on Cash, Cash Equivalents and Restricted Cash	$	(252	)	$	111

Cash, cash equivalents and restricted cash increased by $13.3 million from $23.5 million as of December 31, 2017, to $36.8 million as of June 30, 2018.

Operating Activities

Net cash provided by operating activities increased by $42.1 million from $156.6 million for the six months ended June 30, 2017 to $198.7 million for the six months ended June 30, 2018.

45

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 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; and (e) current volatility in economic conditions and the financial markets. See “Risk Factors” in Part I, Item 1A of our 2017 Annual Report.

Investing Activities

Net cash used for investing activities was $407.5 million for the six months ended June 30, 2018, compared to $167.1 million for the six months ended June 30, 2017. Refer to Note 3, “Real Estate Acquisitions” in our accompanying Consolidated Financial Statements for additional information.

Financing Activities

Net cash provided by financing activities was $222.4 million for the six months ended June 30, 2018, compared to net cash provided by financing activities of $247.3 million for the six months ended June 30, 2017. Refer to Note 9, “Debt and Lines of Credit” and Note 10, “Equity and Mezzanine Securities” in our accompanying Consolidated Financial Statements for additional information.

Financial Flexibility

In July 2017, we entered into a new at the market offering sales agreement (the “Sales Agreement”) with BMO Capital Markets Corp., Merrill Lynch, Pierce, Fenner & Smith Incorporated, Citigroup Global Markets Inc., Robert W. Baird & Co. Incorporated, Fifth Third Securities, Inc., RBC Capital Markets, LLC, BTIG, LLC, Jefferies LLC, Credit Suisse Securities (USA) LLC and Samuel A. Ramirez & Company, Inc. (each, a “Sales Agent;” collectively, the “Sales Agents”), whereby we may offer and sell shares of our common stock, having an aggregate offering price of up to $450.0 million, from time to time through the Sales Agents. The Sales Agents are entitled to compensation in an agreed amount not to exceed 2.0 percent of the gross price per share for any shares sold from time to time under the Sales Agreement.

In April 2017, we amended and restated our credit agreement (the “A&R Credit Agreement”) with Citibank, N.A. (“Citibank”) and certain other lenders. Pursuant to the A&R Credit Agreement, we have a senior revolving credit facility with Citibank and certain other lenders in the amount of $650.0 million, comprised of a $550.0 million revolving loan and a $100.0 million term loan (the “A&R Facility”). The A&R Credit Agreement has a four-year term ending April 25, 2021, which can be extended for two additional six-month periods at our option, subject to the satisfaction of certain conditions as defined in the A&R Credit Agreement. The A&R Credit Agreement also provides for, subject to the satisfaction of certain conditions, additional commitments in an amount not to exceed $350.0 million. If additional borrowings are made pursuant to any such additional commitments, the aggregate borrowing limit under the A&R Facility may be increased up to $1.0 billion.

The A&R Facility bears interest at a floating rate based on the Eurodollar rate plus a margin that is determined based on our leverage ratio calculated in accordance with the A&R Credit Agreement, which margin can range from 1.35 percent to 2.20 percent for the revolving loan and 1.30 percent to 2.15 percent for the term loan. As of June 30, 2018, the margin based on our leverage ratio was 1.35 percent and 1.30 percent on the revolving and term loans, respectively. We had $434.0 million borrowings on the revolving loan and $100.0 million borrowings on the term loan, totaling $534.0 million as of June 30, 2018, with a weighted average interest rate of 3.33 percent.

The A&R Facility provides us with the ability to issue letters of credit. Our issuance of letters of credit does not increase our borrowings outstanding under our line of credit, but does reduce the borrowing amount available. At June 30, 2018 and December 31, 2017, approximately $1.9 million and $1.3 million, respectively, of availability was used to back standby letters of credit.

46

Pursuant to the terms of the A&R Facility, we are subject to various financial and other covenants. We are currently in compliance with these covenants. The most restrictive financial covenants for the A&R Facility are as follows:

Covenant	Requirement	As of June 30, 2018
Maximum Leverage Ratio	<65%	33.8%
Minimum Fixed Charge Coverage Ratio	>1.40	2.75
Minimum Tangible Net Worth	>$2,513,492	$4,093,590
Maximum Dividend Payout Ratio	<95.0%	61.9%

We anticipate meeting our long-term liquidity requirements, such as scheduled debt maturities, large property acquisitions, expansion and development of communities, and Operating Partnership unit redemptions through the issuance of certain debt or equity securities and/or the collateralization of our properties. At June 30, 2018, we had 177 unencumbered properties, of which 61 support the borrowing base for our $650.0 million line of credit. 

From time to time, we may also issue shares of our capital stock, issue equity units in our Operating Partnership, obtain 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 and RV community industry 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. See “Risk Factors” in Part I, Item 1A of our 2017 Annual Report and in Part II, Item 1A of this 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, 2018, our net debt to enterprise value was approximately 28.6 percent (assuming conversion of all common OP units, Series A-1 preferred OP units, Series A-3 preferred OP units, Series A-4 preferred OP units, and Series C preferred OP units to shares of common stock). Our debt has a weighted average maturity of approximately 7.8 years and a weighted average interest rate of 4.4 percent.

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 $536.8 million and $154.8 million as of June 30, 2018 and 2017, respectively, and bears interest at Prime or various LIBOR rates. If Prime or LIBOR increased or decreased by 1.0 percent, our interest expense would have increased or decreased by approximately $1.4 million and $1.5 million for the six months ended June 30, 2018 and 2017, respectively, based on the $291.5 million and $299.2 million 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 Canadian properties 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, 2018 and December 31, 2017, our stockholder’s equity included $84.9 million and $91.5 million from our Canadian subsidiaries, respectively, which represented 3.2 percent and 3.4 percent of total equity, respectively. Based on our sensitivity analysis, a 10.0 percent strengthening of the U.S. dollar against the Canadian dollar would have caused a reduction of $8.5 million and $9.2 million to our total stockholder’s equity at June 30, 2018 and December 31, 2017, respectively.

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, 2018. Based upon this evaluation, our CEO and CFO concluded that our disclosure controls and procedures were effective as of June 30, 2018.

Changes in internal control over financial reporting

There have not been any changes in our internal control over financial reporting during the three months ended June 30, 2018 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Revenue Recognition Policies and Performance Obligations

On January 1, 2018, we adopted FASB Accounting Standards Update (“ASU”) 2014-09 “Revenue from Contracts with Customers” and the other related ASUs and amendments to the codification (collectively “ASC 606”). The core principle of ASC 606 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. A five-step transactional analysis is required to determine how and when to recognize revenue. ASC 606 applies to all contracts with customers, except those that are within the scope of other topics in the FASB accounting standards codification.

As a real estate owner and operator, the majority of our revenue is derived from site and home leases that are accounted for pursuant to ASC 840 “Leases.” For transactions in the scope of ASC 606, we recognize revenue when control of goods or services transfers to the customer, in the amount that we expect to receive for the transfer of goods or provision of services. The adoption of ASC 606 did not result in any change to our accounting policies for revenue recognition. Accordingly, retrospective application to prior periods or a cumulative catch-up adjustment was unnecessary.

Income from real property - Residents in our communities lease the site on which their home is located, and either own or lease their home. Lease revenues for sites and homes fall under the scope of ASC 840, and are accounted for as operating leases with straight-line recognition. Resident leases are generally for one-year or month-to-month terms, and are renewable by mutual agreement from us and the resident, or in some cases, as provided by jurisdictional statute. Non-lease components of our site lease contracts, which are primarily provision of utility services, are accounted for with the site lease as a single lease under ASC 840. Additionally, we include collections of real estate taxes from residents within Income from real property.

Revenue from home sales - Our taxable REIT subsidiary, SHS, sells manufactured homes (“MH”) to current and prospective residents in our communities. Prior to adoption of ASC 606, we recognized revenue for home sales pursuant to ASC 605 “Revenue Recognition,” as manufactured homes are tangible personal property that can be located on any land parcel. Manufactured homes are not permanent fixtures or improvements to the underlying real estate, and were therefore not considered to be subject to the guidance in ASC 360-20 “Real Estate Sales” by the Company. In accordance with the core principle of ASC 606, we recognize revenue from home sales at the time of closing when control of the home transfers to the customer. After closing of the sale transaction, we have no remaining performance obligation.

Rental home revenue - is comprised of rental agreements whereby we lease homes to residents in our communities. We account for these revenues under ASC 840.

Ancillary revenues - are primarily composed of proceeds from restaurant, golf, merchandise and other activities at our recreational vehicle (“RV”) communities. Revenues are recognized at point of sale when control of the good or service transfers to the customer and our performance obligation is satisfied. Sales and other taxes that we collect concurrent with revenue-producing activities are excluded from transaction price.

Interest income - is earned primarily on our notes and collateralized receivables, which includes installment loans for manufactured homes purchased by the Company from loan originators and transferred loans that previously did not meet the requirements for sale accounting. Interest income on these receivables is accrued based on the unpaid principal balances of the underlying loans on a level yield basis over the life of the loans. Interest income is not in the scope of ASC 606. Refer to Notes 4, “Collateralized Receivables and Transfers of Financial Assets” and 5, “Notes and Other Receivables” for additional information.

Broker commissions and other revenues, net - is primarily comprised of brokerage commissions for sales of manufactured homes, where we act as agent and arrange for a third-party to transfer a manufactured home to a customer within one of our communities. Brokerage commission revenues are recognized on a net basis at closing, when the transaction is completed and our performance obligations have been fulfilled. Loan loss reserve expenses for our collateralized receivables and notes receivables are also included herein. Refer to Notes 4, “Collateralized Receivables and Transfers of Financial Assets” and 5, “Notes and Other Receivables” for additional information regarding our loan loss reserves.

Contract Balances

As of June 30, 2018 and December 31, 2017, we had $18.2 million and $13.8 million, respectively, of receivables from contracts with customers. Receivables from contracts with customers are presented as a component of Notes and other receivables on our Consolidated Balance Sheets. These receivables represent balances owed to us for previously completed performance obligations for sales of manufactured homes. Due to the nature of our revenue from contacts with customers, we do not have material contract assets or liabilities that fall under the scope of ASC 606.

Collateralized Receivables and Transfers of Financial Assets

Transfers and Servicing [Abstract]

Transfers Of Financial Assets

Transfers of Financial Assets

We previously completed various transactions with an unrelated entity involving our notes receivable under which we received cash proceeds in exchange for relinquishing our right, title, and interest in certain notes receivable. We have no further obligations or rights with respect to the control, management, administration, servicing, or collection of the installment notes receivable. However, we are subject to certain recourse provisions requiring us to purchase the underlying homes collateralizing such notes, in the event of a note default and subsequent repossession of the home by the unrelated entity. The recourse provisions are considered to be a form of continuing involvement, and therefore these transferred loans did not meet the requirements for sale accounting. We continue to recognize these transferred loans on our balance sheet and refer to them as collateralized receivables. The proceeds from the transfer have been recognized as a secured borrowing.

In the event of a note default and subsequent repossession of a manufactured home by the unrelated entity, the terms of the agreement require us to repurchase the manufactured home. Default is defined as the failure to repay the installment note receivable according to contractual terms. The repurchase price is calculated as a percentage of the outstanding principal balance of the collateralized receivable, plus any outstanding late fees, accrued interest, legal fees, and escrow advances associated with the installment note receivable. The percentage used to determine the repurchase price of the outstanding principal balance on the installment note receivable is based on the number of payments made on the note. In general, the repurchase price is determined as follows:

Number of Payments	Repurchase Percentage
Fewer than or equal to 15	100	%
Greater than 15 but fewer than 64	90	%
Equal to or greater than 64 but fewer than 120	65	%
120 or more	50	%

The transferred assets have been classified as Collateralized receivables, net and the cash proceeds received from these transactions have been classified as Secured borrowings on collateralized receivables within the Consolidated Balance Sheets. The balance of the collateralized receivables was $117.3 million (net of allowance of $0.9 million) and $128.2 million (net of allowance of $0.9 million) as of June 30, 2018 and December 31, 2017, respectively. The receivables have a weighted average interest rate and maturity of 10.0 percent and 14.5 years as of June 30, 2018, and 10.0 percent and 15.3 years as of December 31, 2017.

The outstanding balance on the secured borrowing was $118.2 million and $129.2 million as of June 30, 2018 and December 31, 2017, respectively.

The collateralized receivables earn interest income, and the secured borrowings accrue interest expense at the same interest rates. The amount of interest income and expense recognized was $2.9 million and $3.3 million for the three months ended June 30, 2018 and 2017, respectively, and $5.7 million and $6.6 million for the six months ended June 30, 2018 and 2017, respectively.

The balances of the collateralized receivables and secured borrowings are reduced as the related collateralized receivables are collected from the customers, or as the underlying collateral is repurchased. The change in the aggregate gross principal balance of the collateralized receivables is as follows (in thousands):

	Six Months Ended   June 30, 2018
Beginning balance	$	129,182
Principal payments and payoffs from our customers	(5,866		)

Preferred OP Units

Preferred OP units at June 30, 2018 and December 31, 2017 include $34.7 million of Aspen preferred OP units issued by the Operating Partnership. As of June 30, 2018, these units are convertible indirectly into 453,281 shares of our common stock. Subject to certain limitations, at any time prior to January 1, 2024, the holder of each Aspen preferred OP unit at its option may convert such Aspen preferred OP unit into: (a) if the market price of our common stock is $68.00 per share or less, 0.397 common OP units; or (b) if the market price of our common stock 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 percent of the amount by which the market price of our common stock exceeds $68.00 per share, by (ii) the per-share market price of our common stock. The current preferred distribution rate is 6.5 percent. On January 2, 2024, we are required to redeem all Aspen preferred OP units that have not been converted to common OP units.

Preferred OP units also include $2.7 million and $6.7 million at June 30, 2018 and December 31, 2017, respectively, of Series B-3 preferred OP units, which are not convertible.

In the aggregate, we paid $4.1 million to redeem these units.

Subject to certain limitations, (a) during the 90-day period beginning on each of the tenth through fifteenth anniversaries of the issue date of the applicable Series B-3 preferred OP units, (b) at any time after the fifteenth anniversary of the issue date of the applicable Series B-3 preferred OP units, or (c) after our receipt of notice of the death of the electing holder of a Series B-3 preferred OP unit, each holder of Series B-3 preferred OP units may require us to redeem such holder's Series B-3 preferred OP units at the redemption price of $100.00 per unit. In addition, at any time after the fifteenth anniversary of the issue date of the applicable Series B-3 preferred OP units we may redeem, at our option, all of the Series B-3 preferred OP units of any holder thereof at the redemption price of $100.00 per unit.

Preferred Equity - Sun NG Resorts - mandatorily redeemable

In June 2018, in connection with the investment in Sun NG Resorts, $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 and can be redeemed in the fourth quarter of 2022 at the holders’ option. The Preferred Equity - Sun NG Resorts as of June 30, 2018 was $35.3 million. Refer to Note 3, “Real Estate Acquisitions,” Note 8, “Consolidated Variable Interest Entities,” and Note 10, “Equity and Mezzanine Securities” for additional information.

Lines of Credit

In April 2017, we amended and restated our credit agreement (the “A&R Credit Agreement”) with Citibank, N.A. (“Citibank”) and certain other lenders. Pursuant to the A&R Credit Agreement, we have a senior revolving credit facility with Citibank and certain other lenders in the amount of $650.0 million, comprised of a $550.0 million revolving loan and a $100.0 million term loan (the “A&R Facility”). The A&R Credit Agreement has a four-year term ending April 25, 2021, which can be extended for two additional six-month periods at our option, subject to the satisfaction of certain conditions as defined in the credit agreement. The A&R Credit Agreement also provides for, subject to the satisfaction of certain conditions, additional commitments in an amount not to exceed $350.0 million. If additional borrowings are made pursuant to any such additional commitments, the aggregate borrowing limit under the A&R Facility may be increased up to $1.0 billion.

The A&R Facility bears interest at a floating rate based on the Eurodollar rate plus a margin that is determined based on our leverage ratio calculated in accordance with the A&R Credit Agreement, which margin can range from 1.35 percent to 2.20 percent for the revolving loan and 1.30 percent to 2.15 percent for the term loan. As of June 30, 2018, the margin based on our leverage ratio was 1.35 percent and 1.30 percent on the revolving and term loans, respectively. We had $434.0 million in borrowings on the revolving loan and $100.0 million in borrowings on the term loan, totaling $534.0 million as of June 30, 2018, with a weighted average interest rate of 3.33 percent.

The A&R Facility replaced our $450.0 million credit facility (the “Previous Facility”), which was scheduled to mature on August 19, 2019. The A&R Facility provides, and the Previous Facility provided, us with the ability to issue letters of credit. Our issuance of letters of credit does not increase our borrowings outstanding under our line of credit, but does reduce the borrowing amount available. At June 30, 2018 and December 31, 2017, approximately $1.9 million and $1.3 million, respectively, of availability was used to back standby letters of credit.

We have a $12.0 million manufactured home floor plan facility renewable indefinitely until our lender provides us at least a twelve month notice of their intent to terminate the agreement. The interest rate is 100 basis points over the greater of the prime rate as quoted in the Wall Street Journal on the first business day of each month or 6.0 percent. At June 30, 2018, the effective interest rate was 7.0 percent. The outstanding balance was $2.8 million as of June 30, 2018 and $4.0 million as of December 31, 2017.

Covenants

Pursuant to the terms of the A&R Facility, we are subject to various financial and other covenants. The most restrictive of our debt agreements place limitations on secured borrowings and contain minimum fixed charge coverage, leverage, distribution, and net worth requirements. At June 30, 2018, 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 the debts and other obligations of the Company, any of its other subsidiaries or any other person or entity.

Share-Based Compensation

Share-based Compensation [Abstract]

Share-Based Compensation

Share-Based Compensation

As of June 30, 2018, we had two share-based compensation plans; the Sun Communities, Inc. 2015 Equity Incentive Plan (“2015 Equity Incentive Plan”) and the First Amended and Restated 2004 Non-Employee Director Option Plan (“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.

The following table shows details on grants of equity awards during the six months ended June 30, 2018:

Grant Period	Type	Plan	Shares Granted	Grant Date Fair Value Per Share			Vesting Type	Vesting Anniversary	Percentage
2018	Key Employees	2015 Equity Incentive Plan	16,500	$	88.30	(1)	Time Based	2nd	35.0	%
								3rd	35.0	%
								4th	20.0	%

								6th	5.0	%
2018	Key Employees	2015 Equity Incentive Plan	44,600	$	85.29	(1)	Time Based	20.0% annually over 5 years

2018	Executive Officers	2015 Equity Incentive Plan	90,000	$	65.24	(2)	Market Condition	3rd	100.0	%
2018	Directors	2004 Non-Employee Director Option Plan	16,800	$	85.28	(1)	Time Based	3rd	100.0	%

⁽¹⁾ The fair value of the grants were determined by using the closing price of our common stock on the dates the shares were issued.

⁽²⁾ Share-based compensation for restricted stock awards with market conditions is measured based on an estimate of shares expected to vest. We estimate the fair value of share-based compensation for restricted stock with market conditions using a Monte Carlo simulation. At the grant date our common stock price was $87.24. Based on the Monte Carlo simulation we expect 74.8% of the 90,000 shares to vest.

Vesting

The vesting requirements for 173,993 restricted shares granted to our executives, directors and employees were satisfied during the six months ended June 30, 2018.

Segment Reporting [Abstract]

Segment Reporting

Segment Reporting

We group our operating segments into reportable segments that provide similar products and services. Each operating segment has discrete financial information evaluated regularly by our chief operating decision maker in evaluating and assessing performance. We have two reportable segments: (i) Real Property Operations and (ii) Home Sales and Rentals. The Real Property Operations segment owns, operates, develops, or has an interest in a portfolio of MH and RV communities, and is in the business of acquiring, operating, and expanding MH and RV communities. The Home Sales and Rentals segment offers MH and RV park model sales and leasing services to tenants and prospective tenants of our communities.

Transactions between our segments are eliminated in consolidation. Transient RV revenue is included in the Real Property Operations segment revenues and is expected to approximate $106.5 million annually. This transient RV revenue was recognized 20.7 percent and 20.3 percent in the first and second quarters, respectively, and is expected to be recognized at 41.9 percent and 17.1 percent in the third and fourth quarters, respectively. Transient revenue was $78.0 million for the year ended December 31, 2017. We recognized 27.2 percent in the first quarter, 20.1 percent in the second quarter, 36.9 percent in the third quarter, and 15.8 percent in the fourth quarter.

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

Income Tax Disclosure [Abstract]

Income Taxes

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 stockholders 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 quarter ended June 30, 2018.

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 stockholders 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 (including any applicable alternative minimum tax). 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. The Company is also subject to local income taxes in Canada as a result of the acquisition of Carefree in 2016. 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.

Our taxable REIT subsidiaries are subject to U.S. federal income taxes as well as state and local income and franchise taxes. In addition, our Canadian subsidiaries are subject to income tax in Canada.

Deferred tax assets and liabilities reflect the impact of temporary differences between the amounts of assets and liabilities for financial reporting purposes and the bases 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 U.S. GAAP on our Canadian investments. Generally, full valuation allowances are recorded against almost all U.S. federal deferred tax assets. Deferred tax liabilities of $21.7 million for Canadian entities have been recorded in relation to corporate entities and included in “Other liabilities” in our Consolidated Balance Sheets as of June 30, 2018. There were no U.S. federal deferred tax assets or liabilities included in our Consolidated Balance sheets as of December 31, 2017.

We had no unrecognized tax benefits as of June 30, 2018 and 2017. We do not expect significant changes in tax positions that would result in unrecognized tax benefits within one year of June 30, 2018.

We recorded a current tax expense for federal, state, and Canadian income taxes of approximately $0.2 million for the three months ended June 30, 2018 and a current tax benefit of $7 thousand for the three months ended June 30, 2017. For the six months ended June 30, 2018 and 2017, we recorded a current tax expense of $0.4 million and $0.2 million, respectively.

We recorded $0.1 million of deferred tax expense on our Consolidated Statements of Operations for the three months ended June 30, 2018 and recorded a deferred tax benefit of $0.4 million for the three months ended June 30, 2017. For the six months ended June 30, 2018 and 2017, we recorded a deferred tax benefit of $0.2 million and $0.7 million, respectively.

In 2017, SHS underwent an audit by the Internal Revenue Service for the 2015 tax year. Upon conclusion of the audit in 2018, no adjustment was required.

Fair Value of Financial Instruments

Fair Value Disclosures [Abstract]

Fair Value Of Financial Instruments

Fair Value of Financial Instruments

Our financial instruments consist primarily of cash and cash equivalents, accounts and notes receivable, accounts payable, derivative instruments, and debt.

ASC Topic 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 the Company’s 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;

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 in active markets; and

Level 3—Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

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:

Installment Notes Receivable on Manufactured Homes

The net carrying value of the installment notes receivable on manufactured homes estimates the fair value as the interest rates in the portfolio are comparable to current prevailing market rates (Level 2). Refer to Note 5, “Notes and Other Receivables.”

Long-Term Debt and Lines of Credit

The fair value of long-term debt (excluding the secured borrowing) 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 9, “Debt and Lines of Credit.”

Collateralized Receivables and Secured Borrowings

The fair value of these financial instruments offset each other as our collateralized receivables represent a transfer of financial assets and the cash proceeds received from these transactions have been classified as a secured borrowing on the Consolidated Balance Sheets. The net carrying value of the collateralized receivables estimates the fair value as the interest rates in the portfolio are comparable to current prevailing market rates (Level 2). Refer to Note 4, “Collateralized Receivables and Transfers of Financial Assets.”

Financial Liabilities

We estimate the fair value of our contingent consideration liability based on discounting of future cash flows using market interest rates and adjusting for non-performance risk over the remaining term of the liability (Level 2).

Other Financial Instruments

The carrying values of cash and cash equivalents, accounts receivable, and accounts payable approximate their fair market values due to the short-term nature of these instruments.

The table below sets forth our financial assets and liabilities that required disclosure of fair value on a recurring basis as of June 30, 2018. The table presents the carrying values and fair values of our financial instruments as of June 30, 2018 and December 31, 2017, that were measured using the valuation techniques described above (in thousands). The table excludes other financial instruments such as cash and cash equivalents, accounts receivable, and accounts payable as the carrying values associated with these instruments approximate fair value since their maturities are less than one year.

Accounting Changes and Error Corrections [Abstract]

Recent Accounting Pronouncements

Recent Accounting Pronouncements

Recent Accounting Pronouncements - Adopted

On January 1, 2018, we adopted ASU 2014-09 “Revenue from Contracts with Customers (Topic 606).” Refer to Note 2, “Revenue” for information regarding our adoption of this guidance.

On January 1, 2018 we adopted ASU 2017-09 “Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting.” This update provided clarity and reduced both diversity in practice and cost and complexity when applying the guidance in Topic 718, Compensation - Stock Compensation, regarding a change to the terms or conditions of a share-based payment award. There was no initial impact that resulted from adoption of this guidance; it will be applied should a modification occur.

On January 1, 2018, we adopted ASU 2017-01 “Business Combinations (Topic 805): Clarifying the Definition of a Business.” This update clarified the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The definition of a business affects many areas of accounting including acquisitions, disposals, goodwill, and consolidation.

Under previous guidance, substantially all of our property acquisitions were accounted for as business combinations with identifiable assets and liabilities measured at fair value, and acquisition related costs expensed as incurred and reported as Transaction costs in our Consolidations Statements of Operations.

With the adoption of ASU 2017-01, we expect that substantially all of our future property acquisitions will be accounted for as asset acquisitions. We allocate the purchase price of these properties on a relative fair value basis and capitalize direct acquisition related costs as part of the purchase price. Acquisitions costs that do not meet the criteria to be capitalized will be expensed as incurred and presented as General and administrative costs in our Consolidated Statements of Operations.

On January 1, 2018, we adopted ASU 2016-18 “Statement of Cash Flows (Topic 230): Restricted Cash.” This update required inclusion of restricted cash and restricted cash equivalents with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows.

Our restricted cash consists of amounts primarily held in deposit for tax, insurance and repair escrows held by lenders in accordance with certain debt agreements. Restricted cash is included as a component of Other assets, net on the Consolidated Balance Sheets. Changes in restricted cash are reported in our Consolidated Statements of Cash Flows as operating, investing or financing activities based on the nature of the underlying activity.

The following table reconciles our beginning-of-period and end-of-period balances of cash, cash equivalents and restricted cash for the periods shown (in thousands):

	June 30, 2018		December 31, 2017		June 30, 2017		December 31, 2016
Cash and cash equivalents	$	20,046	$	10,127	$	241,646	$	8,164
Restricted cash	16,755		13,382		20,612		17,149
Cash, cash equivalents and restricted cash	$	36,801	$	23,509	$	262,258	$	25,313

Recent Accounting Pronouncements - Not Yet Adopted

In June 2016, the FASB issued ASU 2016-13 “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” This update replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The amendments in this update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. We are in the initial phases of evaluating how this guidance will impact our accounting policies regarding assessment of, and allowance for, loan losses.

In February 2016, the FASB issued ASU 2016-02 “Leases (Topic 842).” The core principle of this update is that a lessee should recognize the assets and liabilities that arise from leases while the accounting by a lessor is largely unchanged from that applied under previous GAAP. The amendments in this update are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Our income from real property and rental home revenue streams is derived from rental agreements where we are the lessor. As noted above, the lessor accounting model is largely unchanged by this update. We are the lessee in other arrangements, primarily for our executive offices, ground leases at certain communities and certain equipment. We are currently evaluating our inventory of such leases to determine which will require recognition of right of use assets and corresponding lease liabilities, and the related disclosure requirements thereto.

Legal Proceedings

We are involved in various legal proceedings arising in the ordinary course of business. All such proceedings, taken together, are not expected to have a material adverse impact on our results of operations or financial condition.

Catastrophic Weather Related Estimates

In September 2017, our communities in Florida and Georgia sustained damages from Hurricane Irma. The table below sets forth estimated losses (in millions). Future changes to estimated losses will be recognized in the period(s) in which they are determined.

We maintain property, casualty, flood and business interruption insurance for our community portfolio, subject to customary deductibles and limits. The table below sets forth estimated insurance recoveries (in millions). Actual insurance recoveries could vary significantly from our estimates. Future changes to estimated insurance recoveries will be recognized in the period(s) in which they are determined.

	Six Months Ended June 30, 2018
Total estimated insurance receivable - December 31, 2017	$	23.7
Change in estimated insurance recoveries	7.8
Advances from insurer	(9.4		)
Total estimated insurance receivable - June 30, 2018	$	22.1

Changes in estimated insurance recoveries for damages during the six months ended June 30, 2018, were primarily the result of incremental invoices for which the total costs exceeded the applicable deductible. The change in estimated losses and changes in estimated insurance recoveries during the three and six months ended June 30, 2018, resulted in a net loss of $0.1 million and a net gain of $2.2 million, respectively to Catastrophic weather related charges, net in our Consolidated Statements of Operations.

We are actively working with our insurer on claims for lost earnings and redevelopment costs greater than the asset impairment charge for the three Florida Keys communities. The three impaired Florida Keys communities will require redevelopment followed by a tenant lease-up period. As such, we currently cannot estimate a date when operating results will be restored to pre-hurricane levels. Our business interruption insurance policy provides for up to 60 months of coverage from the date of restoration.

Subsequent Events

In July 2018, we issued 193,001 shares of common stock through our At-the-Market equity sales program at a weighted average price of $97.93 per share. Net proceeds from the sales were $18.7 million.

In July 2018, we acquired The Sands RV & Golf Resort (“The Sands”) for $14.3 million, an RV resort that contains 507 RV sites and is located in Desert Hot Springs, California.

In July 2018, the Company entered into a $228.0 million collateralized term loan with a 4.10 percent fixed rate and a 20 year term.

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

2018	Directors	2004 Non-Employee Director Option Plan	16,800	$	85.28	(1)	Time Based	3rd	100.0	%

⁽¹⁾ The fair value of the grants were determined by using the closing price of our common stock on the dates the shares were issued.

⁽²⁾ Share-based compensation for restricted stock awards with market conditions is measured based on an estimate of shares expected to vest. We estimate the fair value of share-based compensation for restricted stock with market conditions using a Monte Carlo simulation. At the grant date our common stock price was $87.24. Based on the Monte Carlo simulation we expect 74.8% of the 90,000 shares to vest.
