1.      Basis of Presentation

Sun Communities, Inc., a Maryland corporation, and all wholly-owned or majority-owned and controlled subsidiaries, including Sun Communities Operating Limited Partnership (the “Operating Partnership”) and Sun Home Services, Inc. (“SHS”) are referred to herein as the "Company," "us," "we," and "our".

We follow accounting standards set by the Financial Accounting Standards Board ("FASB"). FASB sets generally accepted accounting principles ("GAAP"), which we follow to ensure that we consistently report our financial condition, results of operations, and cash flows. References to GAAP issued by the FASB in these footnotes are to the FASB Accounting Standards Codification.

These unaudited Consolidated Financial Statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial information and in accordance with GAAP. Pursuant to the SEC rules and regulations we present interim disclosures and certain information and footnote disclosures as required. Accordingly, the unaudited Consolidated Financial Statements do not include all of the information and footnotes required by GAAP for complete financial statements. The accompanying unaudited Consolidated Financial Statements reflect, in the opinion of management, all adjustments, including adjustments of a normal and recurring nature, necessary for a fair presentation of the interim financial statements. All intercompany transactions have been eliminated in consolidation. Certain reclassifications have been made to prior periods' financial statements in order to conform to current period presentation.

The results of operations for interim periods are not necessarily indicative of results that may be expected for any other interim period or for the full year. These unaudited Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2015 as filed with the SEC on February 23, 2016 (the “2015 Annual Report”). These statements have been prepared on a basis that is substantially consistent with the accounting principles applied in our 2015 Annual Report.

2.      Real Estate Acquisitions

Carefree Acquisition

On June 9, 2016, pursuant to a Stock Purchase Agreement dated March 22, 2016, the Company through the Operating Partnership acquired from Carefree Communities Intermediate Holdings, L.L.C. (the "Seller") all of the issued and outstanding shares of common stock of Carefree Communities Inc. ("Carefree Communities") or ("Carefree"). Carefree Communities directly or indirectly owns 103 manufactured home (“MH”) and recreational vehicle (“RV”) communities, comprising over 27,000 sites.

The aggregate purchase price for the acquisition was $1.68 billion. At the closing, the Company issued the Seller 3,329,880 shares of its common stock (the "Acquisition Shares") at an issuance price of $67.57 per share (or $225.0 million in common stock), and the Operating Partnership paid the balance of the purchase price, or $1.455 billion, in cash. Approximately $1.0 billion of the cash payment was applied simultaneously to pay off debt on the properties owned by Carefree Communities. The Operating Partnership funded the cash portion of the purchase price in part with the proceeds of the Fannie Mae Financing and the NML Financing (See Note 8).

On March 30, 2016, we closed on an underwritten public offering of 6,037,500 shares of common stock at a price of $66.50 per share.   The net proceeds from the offering of $385.4 million were used to fund a portion of the purchase price for the acquisition of the Carefree Communities.

The Carefree acquisition closed on June 9, 2016. The Company has recorded preliminary: investment in property, identifiable current assets, identifiable current liabilities, and inventory acquired. The Company will allocate the "investment in property" balances to the respective balance sheet line items during the third quarter 2016 upon completion of a purchase price allocation in accordance with ASC 805, Business Combinations.

3.      Collateralized Receivables and Transfers of Financial Assets

We 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 less than 64	90	%
Equal to or greater than 64 but less 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 $144.0 million (net of allowance of $0.7 million) and $139.8 million (net of allowance of $0.7 million) as of June 30, 2016 and December 31, 2015, respectively.

Origen Financial Services, LLC (“OFS LLC”)

At June 30, 2016 and December 31, 2015, we had a 22.9% ownership interest in OFS LLC, an entity formed to originate manufactured housing installment contracts. We have suspended equity accounting as the carrying value of our investment is zero.

Origen Financial, Inc. (“Origen”)

Through Sun OFI, LLC, a taxable REIT subsidiary, we owned 5,000,000 shares of common stock in Origen, which approximated an ownership interest of 19.3%. We had suspended equity accounting for this investment as the carrying value of our investment was zero. In January 2015, Origen completed the sale of substantially all of its assets to an affiliate of GoldenTree Asset Management, LP and announced its intention to dissolve and liquidate. During the second quarter of 2015, and as disclosed in a press release on March 30, 2015, Origen made an initial distribution of $1.50 per share to its stockholders of record as of April 13, 2015. During the second quarter of 2015, we received an initial distribution of $7.5 million from Origen. No distributions have been received as of June 30, 2016. We sold all 5,000,000 shares for aggregate proceeds of $500,000 on July 22, 2016.

7.      Consolidated Variable Interest Entities

In 2016, the Company adopted Accounting Standards Update (“ASU”) No. 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis. The Company evaluated the application of ASU No. 2015-02 and concluded that no change was required to its accounting of its interests in less than wholly owned joint ventures, however, the Operating Partnership now meets the criteria as a variable interest entity. The Company’s significant asset is its investment in the Operating Partnership, and consequently, substantially all of the Company’s assets and liabilities represent those assets and liabilities of the Operating Partnership.

Other VIEs that are consolidated include: Rudgate Village SPE, LLC; Rudgate Clinton SPE, LLC; Rudgate Clinton Estates SPE, LLC (the “Rudgate Borrowers”); and Wildwood Village Mobile Home Park ("Wildwood"). We evaluated our arrangements with these properties under the guidance set forth in FASB Accounting Standard Codification ("ASC") ASC Topic 810 "Consolidation". We concluded that the Rudgate Borrowers and Wildwood qualify as VIEs as we are the primary beneficiary and hold controlling financial interests in these entities due to our power to direct the activities that most significantly impact the economic performance of the entities, as well as our obligation to absorb the most significant losses and our rights to receive significant benefits from these entities. As such, the transactions and accounts of these VIEs are included in the accompanying Consolidated Financial Statements.

Collateralized Term Loans

In June 2016, 17 subsidiaries of the Operating Partnership entered into a Master Credit Facility Agreement (the "Fannie Mae Credit Agreement") with Regions Bank, as lender. Pursuant to the Fannie Mae Credit Agreement, Regions Bank loaned a total of $338.0 million under a senior secured credit facility, comprised of twoten-year term loans in the amount of $300.0 million and $38.0 million, respectively (collectively the "Fannie Mae Financing"). The $300.0 million term loan bears interest at 3.69% per year and the $38.0 million term loan bears interest at 3.67% per year for a blended rate of 3.688% per year. The Fannie Mae Financing provides for principal and interest payments which will be due based on a 30-year amortization.

The Fannie Mae Financing is secured by mortgages encumbering 17 MH communities comprised of real and personal property owned by the borrowers. Additionally, the Company and the Operating Partnership have provided a guaranty of the non-recourse carve-out obligations of the borrowers under the Fannie Mae Financing.

Also in June 2016, three subsidiaries of the Operating Partnership entered into mortgage loan documents (the "NML Loan Documents") with The Northwestern Mutual Life Insurance Company ("NML"). Pursuant to the NML Loan Documents, NML made three portfolio loans to the subsidiary borrowers in the aggregate amount of $405.0 million. NML loaned $162.0 million under a ten-year term loan to two of the subsidiary borrowers (the "Portfolio A Loan"). The Portfolio A Loan bears interest at 3.53% per year and is secured by deeds of trust encumbering seven MH communities and one RV community. NML also loaned $163.0 million under a 12-year term loan (the "Portfolio B Loan") to one subsidiary which is also a borrower under the Portfolio A Loan. The Portfolio B Loan bears interest at 3.71% per year and is secured by deeds of trust and a ground lease encumbering eight MH communities. NML also loaned $80.0 million under a 12-year term loan (the "Portfolio C Loan" and, collectively, with the Portfolio A Loan and the Portfolio B Loan, the "NML Financing") to one subsidiary borrower. The Portfolio C Loan bears interest at 3.71% per year and is secured by a mortgage encumbering one RV community. All of the MH and RV communities that secure the NML Financing were acquired as part of the Carefree Communities acquisition (See Note 2).

The NML Financing is generally non-recourse, however, the borrowers under the NML Financing and the Operating Partnership are responsible for certain customary non-recourse carveouts. In addition, the NML Financing will be fully recourse to the subsidiary borrowers and the Operating Partnership if: (a) the borrowers violate the prohibition on transfer covenants set forth in the loan documents; or (b) a voluntary bankruptcy proceedings is commenced by the borrowers or an involuntary bankruptcy, liquidation, receivership or similar proceeding has commenced against the borrowers and remains undismissed for a period of 90 days.

In March 2015, in relation to the acquisition of Meadowlands, we assumed a $6.3 million mortgage with an interest rate of 6.5% and a remaining term of 6.5 years. Also, in relation to this acquisition, we entered into a note payable with the seller for $2.4 million that bears no interest but is payable in three equal yearly installments beginning in March 2016. During the first half of 2016, we paid the first of the yearly installments of $0.8 million.

The collateralized term loans totaling $2.8 billion as of June 30, 2016, are secured by 189 properties comprised of 75,876 sitesrepresenting approximately $2.7 billion of net book value.

Secured Borrowing

See Note 3, "Collateralized Receivables and Transfers of Financial Assets", for additional information regarding our collateralized receivables and secured borrowing transactions.

Preferred OP Units

Included in preferred OP units is $34.7 million of Aspen preferred OP units issued by the Operating Partnership which, as of June 30, 2016, are convertible indirectly into 495,552 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% 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%. On January 2, 2024, we are required to redeem all Aspen preferred OP units that have not been converted to common OP units.

Lines of Credit

In August, 2015, we amended and restated our senior revolving credit facility with Citibank, N.A. and certain other lenders in the amount of $450.0 million, comprised of a $392.0 million revolving loan and $58.0 million term loan (the "Facility"). The Facility has a four year term ending August 19, 2019, 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 credit agreement also provides for, subject to the satisfaction of certain conditions, additional commitments in an amount not to exceed $300.0 million. If additional borrowings are made pursuant to any such additional commitments, the aggregate borrowing limit under the Facility may be increased up to $750.0 million. The 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 credit agreement, which can range from 1.40% to 2.25% for the revolving loan and 1.35% to 2.20% for the term loan. As of June 30, 2016, the margin on our leverage ratio was 1.45% and 1.40% on the revolving and term loans, respectively. We had $300.0 million on the revolving loan and $58.0 million on the term loan totaling $358.0 million in borrowings as of June 30, 2016, with a weighted average interest rate of 1.89%. As of December 31, 2015 we had no borrowings on the revolving loan and $25.0 million in borrowings on the term loan totaling $25.0 million in borrowings.

The 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, 2016 and December 31, 2015, approximately $4.2 million and $3.4 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%. At June 30, 2016, the effective interest rate was 7.0%.  At June 30, 2016 and December 31, 2015, there was no outstanding balance.

Covenants

Pursuant to the terms of the 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, 2016, we were in compliance with all covenants.

9.      Equity and Mezzanine Securities

In June 2015, we entered into an At the Market Offering Sales Agreement (the "Sales Agreement") with BMO Capital Markets Corp., Merrill Lynch, Pierce, Fenner and Smith Incorporated and Citigroup Global Markets Inc. (collectively, the "Sales Agents"). Pursuant to the Sales Agreement, we may offer and sell shares of our common stock, having an aggregate offering price of up to $250.0 million, from time to time through the Sales Agents. Each Sales Agent is entitled to compensation in an agreed amount not to exceed 2.0% of the gross price per share for any shares sold through it from time to time under the Sales Agreement. During the second quarter of 2016, 485,000 shares of common stock were issued at the prevailing market price of our common stock at the time of each sale with a weighted average sales price of $71.86, and we received net proceeds of approximately $34.4 million.

Net proceeds from the offering were approximately $385.4 million after deducting discounts and expenses related to the offering, which we used to fund a portion of the purchase price for the acquisition of Carefree Communities.

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 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 under this buyback program during the six months ended June 30, 2016 or 2015. There is no expiration date specified for the buyback program.

Subject to certain limitations, common OP unit holders can convert their common OP units into an equivalent number of shares of common stock at any time. During the six months ended June 30, 2016 and 2015, there were 0 and 17,500 common OP units converted to shares of common stock, respectively.

Subject to certain limitations, Series A-1 preferred OP unit holders may convert each Series A-1 preferred OP units to approximately 2.439 shares of our common stock at any time.

On June 30, 2016, cash payments of approximately $0.7 million were made to Series A-4 Preferred Stock stockholders of record as of June 17, 2016.

10.      Share-Based Compensation

During the three months ended June 30, 2016, we granted 76,000 shares of restricted stock to key employees under the Sun Communities Inc. 2015 Equity Incentive Plan. The shares had a fair value of $69.53 per share and will vest as follows: April 18, 2019: 35%, April 18, 2020: 35%, April 18, 2021: 20%, April 18, 2022: 5%, and April 18, 2023: 5%. The fair value of issued grants was determined by using the closing price of our common stock on the date the shares were issued.

During the three months ended March 31, 2016, we granted 16,800 shares of restricted stock to our non-employee directors under our First Amended and Restated 2004 Non-Employee Director Option Plan. The awards vest on March 15, 2019, and had a fair value of $69.45 per share. The fair value was determined by using the closing share price of our common stock on the date the shares were issued.

During the three months ended March 31, 2016, we granted 130,000 shares of restricted stock to our executive officers under the Sun Communities, Inc. 2015 Equity Incentive Plan.

The remaining 65,000 shares are subject to market and performance conditions with multiple tranches that vest through March 2022. Share-based compensation for restricted stock awards with performance 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.

11. 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, and develops MH communities and RV communities and is in the business of acquiring, operating, and expanding MH and RV communities.  The Home Sales and Rentals segment offers manufactured home 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 $60.2 million annually. This transient RV revenue was recognized 16.9% and 18.1% in the first and second quarters, respectively, and is expected to be 45.3% and 19.7% in the third and fourth quarters, respectively. In 2015, transient revenue was $39.7 million. We recognized 22.5% in the first quarter, 17.7% in the second quarter, 45.2% in the third quarter, and 14.6% in the fourth quarter.

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

12.    Income Taxes

We and Carefree Communities, Inc have each elected to be taxed as a real estate investment trust (“REIT”) pursuant to Section 856(c) of the Internal Revenue Code of 1986 (“Code”), as amended. In order for us to qualify as a REIT, at least 95% of our gross income in any year must be derived from qualifying sources. In addition, a REIT must distribute annually at least 90% of its REIT ordinary taxable income to its stockholders and meet other tests.

21

SUN COMMUNITIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Qualification as a REIT involves the satisfaction of numerous requirements (some on an annual and quarterly basis) established under highly technical and complex Code provisions for which there are only 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, 2016.

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, U.S. federal income taxes and excise taxes on our undistributed income.

Our various taxable REIT subsidiaries are subject to U.S. federal income taxes. Due to the Carefree acquisition, certain of our properties are also subject to Canadian income taxes. Our 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 and depreciation. Full valuation allowances are generally recorded against all U.S. federal deferred tax assets. For Canadian purposes, a minimal amount of deferred tax asset is recorded in relation to a corporate entity and included in “Other assets, net” in our Consolidated Balance Sheets as of June 30, 2016. No federal deferred tax asset is included in "Other assets, net," in our Consolidated Balance Sheets as of June 30, 2016 and December 31, 2015.

We had no unrecognized tax benefits as of June 30, 2016 and 2015. We expect no significant increases or decreases in unrecognized tax benefits due to changes in tax positions within one year of June 30, 2016.

We recorded a provision for federal, state, and Canadian income taxes of approximately $0.1 million and $0.1 million for the three months ended June 30, 2016, and 2015, respectively, and $0.3 million and $0.2 million for the six months ended June 30, 2016 and 2015, respectively.

13.    Earnings Per Share

We have outstanding stock options, unvested restricted shares, Series A Preferred Stock, and Series A-4 Preferred Stock, and our Operating Partnership has: outstanding common OP units; Series A-1 preferred OP units; Series A-3 preferred OP units; Series A-4 preferred OP units; Series C preferred OP units; and Aspen preferred OP Units, which, if converted or exercised, may impact dilution.

14. Derivative Instruments and Hedging Activities

Our objective in using interest rate derivatives is to manage exposure to interest rate movements thereby minimizing the effect of interest rate changes and the effect it could have on future cash flows. Interest rate caps are used to accomplish this objective. We do not enter into derivative instruments for speculative purposes nor do we have any swaps in a hedging arrangement.

The following table provides the terms of our interestrate derivative contracts that were in effect as of June 30, 2016:

Type	Purpose	Effective Date	Maturity Date	Notional  (in millions)		Based on	Variable Rate	Fixed Rate	Spread	Effective Fixed Rate

In accordance with ASC Topic 815, "Derivatives and Hedging"("ASC 815"), derivative instruments are recorded at fair value in "Other assets, net" or "Other liabilities" on the Consolidated Balance Sheet. As of June 30, 2016 and December 31, 2015, the fair value of the derivatives was zero.

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" ("ASC 820"), requires disclosure about how fair value is determined 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.

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:

Derivative Instruments

The derivative instruments held by us are interest rate cap agreements for which quoted market prices are indirectly available. For those derivatives, we use model-derived valuations in which all significant inputs and significant value drivers are observable in active markets provided by brokers or dealers to determine the fair value of derivative instruments on a recurring basis (Level 2). See Note 14 for Derivative Instruments.

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). See Note 4 for Installment Notes Receivable.

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). See Note 8 for Long-Term 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). See Note 3 for Collateralized Receivables and Secured Borrowing.

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 their fair values on a recurring basis as of June 30, 2016. The table presents the carrying values and fair values of our financial instruments as of June 30, 2016 and December 31, 2015 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 because the carrying values associated with these instruments approximate fair value since their maturities are less than one year.

16.    Recent Accounting Pronouncements

In March 2016, the FASB issued ASU 2016-09 "Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting". ASU 2016-09 is intended to simplify several aspects of the accounting for share-based payments. The guidance will be effective for fiscal years beginning after December 15, 2016, including interim periods within that year. The Company is in the process of evaluating the impact of the adoption of this ASU.

In February 2016, the FASB issued ASU 2016-02 "Leases (Topic 842)". The core principle of Topic 842 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. The Company is currently evaluating the impact of the adoption of this new standard.

In April 2015, the FASB issued ASU 2015-03 "Interest - Imputation of Interest (Subtopic 835-30) Simplifying the Presentation of Debt Issuance Costs" ("ASU 2015-03"). This amendment requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. In August 2015, the FASB issued ASU 2015-15 "Interest - Imputation of Interest (Subtopic 835-30) Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements" ("ASU 2015-15"). This amendment provides additional guidance within ASU 2015-03 for debt issuance costs related to line of credit arrangements. These amendments are effective for fiscal years beginning after December 15, 2015, and interim periods within those years, with early adoption permitted. Entities should apply the amendments retrospectively. ASU 2015-15 provides commentary that the SEC staff would not object to an entity deferring and presenting costs associated with line of credit arrangements as an asset and subsequently amortizing them ratably over the term of the revolving debt arrangement. We adopted these amendments as of March 31, 2016, which resulted in a reclassifying of deferred financing costs of $8.2 million from "Other assets, net" to "Mortgage loans payable" on the Consolidated Balance Sheets as of March 31, 2016. The debt issuance costs related to our line of credit facility remain classified as an asset on the Consolidated Balance Sheets. This change was applied throughout this document where applicable.

In February 2015, the FASB issued ASU No. 2015-02 "Consolidation (Topic 810) Amendments to the Consolidation Analysis" ("ASU 2015-02") which modified the evaluation of whether limited partnerships and similar legal entities are variable interest entities or voting interest entities. All entities are subject to reevaluation under the revised consolidation model. The Company is the sole general partner in a limited partnership, and as such, the Company has complete control in conducting all business activities associated with the Partnership. Limited partners do not have kickout rights or participating rights. The Company adopted ASU 2015-02 as of March 31, 2016 and fully consolidates the activities of the Operating Partnership within its Consolidated Financial Statements under the variable interest entity model as it is the primary beneficiary. There was no impact to the Consolidated Financial Statements as the Company previously consolidated under the voting interest entity model.

In May 2014, the FASB issued ASU 2014-09 "Revenue from Contracts with Customers (Topic 606)" ("ASU 2014-09"). The objective of this amendment is to establish a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will supersede most of the existing revenue recognition guidance, including industry-specific guidance. The core principle is that a company 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. In applying this amendment, companies will perform a five-step analysis of transactions to determine when and how revenue is recognized. This amendment applies to all contracts with customers except those that are within the scope of other topics in the FASB ASC. This amendment is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period; early adoption is not permitted. An entity should apply the amendments using either the full retrospective approach or retrospectively with a cumulative effect of initially applying the amendments recognized at the date of initial application. We are currently evaluating the methods of adoption and the impact that the adoption of ASU 2014-09 may have on our Consolidated Financial Statements.

17.   Commitments and Contingencies

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.

18.   Subsequent Event

On July 22, 2016, we sold our entire interest in Origen consisting of 5,000,000 shares of Origen's common stock, in a private transaction for proceeds of $500,000.

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 2015 Annual Report. Capitalized terms are used as defined elsewhere in this Form 10-Q.

OVERVIEW

We are a fully integrated, self-administered and self-managed REIT. As of June 30, 2016, we owned and operated a portfolio of 337 developed properties located in 29 states throughout the United States and one province in Canada, including 227 MH communities, 84 RV communities, and 26 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 2015 Annual Report.

SUPPLEMENTAL MEASURES

In addition to the results reported in accordance with GAAP, we have provided information regarding Net Operating Income (“NOI”) in the following tables. NOI is derived from revenues minus property operating and maintenance expenses and real estate taxes. We use NOI as the primary basis to evaluate the performance of our operations. A reconciliation of NOI to net income attributable to Sun Communities, Inc. common stockholders is included in “Results of Operations” below.

We believe that NOI is helpful to investors and analysts as a 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 management tool 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, and therefore, NOI is a measure of the operating performance of our properties rather than of the Company overall.  We believe that these costs included in net income often have no effect on the market value of our property and therefore limit its use as a performance measure. In addition, such expenses are often incurred at a parent company level and therefore are not necessarily linked to the performance of a real estate asset.

NOI should not be considered a substitute for the reported results prepared in accordance with GAAP. NOI should not be considered as an alternative to net income as an indicator of our financial performance, or to cash flows as a measure of liquidity; nor is it indicative of funds available for our cash needs, including our ability to make cash distributions.  NOI, as determined and presented by us, may not be comparable to related or similarly titled measures reported by other companies.

We also provide information regarding Funds From Operations (“FFO”).  We consider FFO an appropriate supplemental measure of the financial and operational performance of an equity REIT. Under the National Association of Real Estate Investment Trusts (“NAREIT”) definition, FFO represents net income (loss) (computed in accordance with GAAP), excluding extraordinary items (as defined under GAAP), and gain (loss) on sales of depreciable operating property, plus real estate related depreciation and amortization (excluding amortization of financing costs), and after adjustments for unconsolidated partnerships and joint ventures. Management also uses FFO excluding certain items, a non-GAAP financial measure, which excludes certain gain and loss items that management considers unrelated to the operational and financial performance of our core business. We believe that this provides investors with another financial measure of our operating performance that is more comparable when evaluating period over period results. A discussion of FFO, FFO excluding certain items, a reconciliation of FFO to net income, and FFO to FFO excluding certain items are included in the presentation of FFO in our “Results of Operations” below.

28

SUN COMMUNITIES, INC.

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, and develops MH communities and RV communities throughout the U.S. and is in the business of acquiring, operating, and expanding MH and RV communities. The Home Sales and Rentals segment offers manufactured home sales and leasing services to tenants and prospective tenants of our communities. We evaluate segment operating performance based on NOI and gross profit.

SUN COMMUNITIES, INC.

REAL PROPERTY OPERATIONS – SAME COMMUNITY

A key management tool used when evaluating performance and growth of our properties is a comparison of Same Communities. Same Communities consist of properties owned and operated throughout 2016 and 2015.  The Same Community data may change from time-to-time depending on acquisitions, dispositions, management discretion, significant transactions, or unique situations. The Same Community data in this Form 10-Q includes all properties which we have owned and operated continuously since January 1, 2015. All communities from the American Land Lease portfolio acquisition are included within Same Communities.

In order to evaluate the growth of the Same Communities, management has classified certain items differently than our GAAP statements. The reclassification difference between our GAAP statements and our Same Community portfolio is 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 reclassify these amounts 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, 2016 and 2015:

⁽¹⁾  Overall occupancy (%) includes MH and annual/seasonal RV sites, and excludes recently completed but vacant expansion sites and transient RV sites.

⁽²⁾ Overall occupancy (%) for 2015 has been adjusted to reflect incremental growth year over year from filled expansion sites and the conversion of transient RV sites to annual/seasonal RV sites.

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

⁽⁴⁾  Three months ended June 30, 2015 excludes $1.1 million of first year expenses for properties acquired in late 2014 and 2015 incurred

to bring the properties up to Sun's operating standards. These costs did not meet the Company's capitalization policy.

The 6.9% growth in NOI is primarily due to increased revenues of $6.1 million partially offset by additional expenses of $0.9 million.

Income from real property revenue consists of MH and RV site rent, and miscellaneous other property revenues. The 5.6% growth in income from real property is primarily due to increased revenue from our MH and RV portfolio due to the 2.5% occupancy gain and a 3.2% increase in the weighted average rental rate.

SUN COMMUNITIES, INC.

Property operating expenses increased approximately $0.9 million, or 2.7%, compared to 2015. Of the increase, salaries and wages increased $0.3 million; benefit costs increased $0.5 million; workers compensation costs decreased $0.5 million; property and casualty insurance expense decreased $0.3 million; and utilities increased $0.1 million primarily due to an increase in water and sewer expense, net of recoveries. Real estate taxes increased $0.9 million primarily due to increased tax appraisals in several communities located in Colorado and Texas.

Weighted average monthly rental rate, end of period	$	868	$	835	$	33		4.0	%

⁽¹⁾ The renter’s monthly payment includes the site rent and an amount attributable to the leasing of the home. The site rent is reflected in the Real Property Operations segment. 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.

The 1.8% increase in NOI is primarily a result of an increase in rental rates during the three months ended June 30, 2016 as compared to June 30, 2015, offset by a slight decline in the number of occupied rental homes. The decrease in operating and maintenance expenses of $(0.1) million was primarily a result of declines in commissions, taxes, and marketing expenses, offset by an increase in refurbishment costs of the home after a renter moves out.

Income from real property revenue consists of MH and RV site rent, and miscellaneous other property revenues.  The 6.1% growth in income from real property is primarily due to increased revenue from our MH and RV portfolio as a result of a 2.5% increase in occupancy and a 3.2% increase to our weighted average rental rate.

Of the increase, salaries and wages increased $0.8 million; benefit costs increased $0.8 million; workers compensation costs decreased $0.6 million; property and casualty insurance expense decreased $0.2 million; utilities increased $0.3 million primarily due to an increase in water and sewer expense, net of recoveries and a rubbish removal increase of $0.2 million due to higher occupancy; supplies and repair expense increased $0.1 million and other miscellaneous expenses increased $0.2 million. Real estate taxes increased $1.6 million due to increased tax assessments primarily in Colorado and Texas.

⁽¹⁾ The renter’s monthly payment includes the site rent and an amount attributable to the leasing of the home. The site rent is reflected in the Real Property Operations segment. 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.

The 1.9% growth in NOI is primarily a result of increased monthly rental rates as indicated in the table above partially offset by a decline in the number of occupied rental units.

The increase in operating and maintenance expenses of $0.2 million was primarily a result of a $1.2 million increase in repairs and refurbishment expenses related to the refurbishment of the home after a renter moves out, offset by decreases in commission expenses of $0.4 million, decreases in taxes and insurance of $0.3 million, and decreases of $0.3 million in marketing expenses.

Home sales gross profit decreased $0.3 million on new home sales and increased $4.9 million on pre-owned home sales. The decreased profit on new home sales is primarily the result of a slight decline in new home sale volume and lower gross margins on homes sold. The increased profit on pre-owned homes sales is due to the increase in sales volume and per unit sales prices.

Ancillary revenues, net increased primarily due to an increase of $0.8 million in RV vacation rental income and increases of $0.8 million in golf course, restaurant and merchandise sales revenue at RV resorts.

Interest income increased primarily due to an increase in interest income on collateralized receivables of $0.6 million.

Brokerage commissions and other revenues decreased primarily due to a higher loan loss reserve in 2016 as compared to 2015.

Home selling expenses increased primarily due to increased commissions of $1.0 million and increased salaries, wages and related taxes of $0.6 million.

FUNDS FROM OPERATIONS

We provide information regarding FFO as a supplemental measure of financial and operational performance. FFO is defined by NAREIT as net income (loss) (computed in accordance with GAAP), excluding extraordinary items (as defined under GAAP), and gain (loss) on sales of depreciable operating property, plus real estate related depreciation and amortization (excluding amortization of financing costs), and after adjustments for unconsolidated partnerships and joint ventures. Due to the variety among owners of identical assets in similar condition (based on historical cost accounting and useful life estimates), we believe excluding gains and losses related to sales of previously depreciated operating real estate assets, impairment and excluding real estate asset depreciation and amortization, provides a better indicator of our operating performance. FFO is a useful supplemental measure of our operating performance because it reflects the impact to operations from trends in occupancy rates, rental rates, and operating costs, providing perspective not readily apparent from net income (loss). Management believes that 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. Management, the investment community, and banking institutions routinely use FFO, together with other measures, to measure operating performance in our industry. Further, management uses FFO for planning and forecasting future periods.

Because FFO excludes significant economic components of net income (loss) including depreciation and amortization, FFO should be used as an adjunct to net income (loss) and not as an alternative to net income (loss). The principal limitation of FFO is that it does not represent cash flow from operations as defined by GAAP and is a supplemental measure of performance that does not replace net income (loss) as a measure of performance or net cash provided by operating activities as a measure of liquidity. In addition, 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 only provides investors with an additional performance measure. FFO is compiled in accordance with its interpretation of standards established by NAREIT, which may not be comparable to FFO reported by other REITs that do not define the term in accordance with the current NAREIT definition or that interpret the current NAREIT definition differently.

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 look for opportunities to expand our development pipeline and acquire existing communities. We also intend to continue to strengthen our capital and liquidity positions by continuing to focus 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 unsecured credit facility, and the use of debt and equity offerings under our shelf registration statement.

During the six months ended June 30, 2016, we acquired the Carefree portfolio of 103 communities, plus one other MH community and two other RV communities. See Note 2 to our Consolidated Financial Statements for details on the 2016 acquisitions and Note 8 to our Consolidated Financial Statements for related debt transactions.

We will continue to evaluate acquisition opportunities that meet our criteria for acquisition. On March 30, 2016, we closed on an underwritten public offering of 6,037,500 shares of common stock at a price of $66.50 per share.   The net proceeds from the offering were used to fund a portion of the purchase price for the acquisition of Carefree Communities. See Note 2 to our Consolidated Financial Statements for additional details on the Carefree Communities acquisition. Should additional investment opportunities arise in 2016, we intend to finance the acquisitions through available cash, secured financing, draws on our credit facilities, the assumption of existing debt on the properties, and the issuance of certain equity securities.

During the six months ended June 30, 2016, we invested $17.8 million in the acquisition of homes intended for the Rental Program net of proceeds from third-party financing from home sales. Expenditures for 2016 will 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,
	2016			2015
Net Cash Provided by Operating Activities	$	129,048		$	92,393
Net Cash Used for Investing Activities	$	(1,468,615	)	$	(304,852	)
Net Cash Provided by Financing Activities	$	1,325,922		$	140,930

Cash and cash equivalents decreased by $13.7 million from $45.1 million as of December 31, 2015, to $31.4 million as of June 30, 2016.

Operating Activities

Net cash provided by operating activities increased by $36.7 million from $92.4 million for the six months ended June 30, 2015 to $129.0 million for the six months ended June 30, 2016.

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 2015 Annual Report.

Investing Activities

Net cash used for investing activities was $1.5 billion for the six months ended June 30, 2016, compared to $304.9 million for the six months ended June 30, 2015. The increase is primarily due to increased cash used for the acquisition of properties, as a result of the Carefree Community acquisition.

Financing Activities

Net cash provided by financing activities was $1.3 billion for the six months ended June 30, 2016, compared to $140.9 million for the six months ended June 30, 2015. The increase is primarily due to a significant increase in our equity offerings in 2016 to fund the Carefree Community acquisition, in addition to new debt issuances specific to the Carefree acquisition as referenced in Note 8 and an increase in borrowings on the line of credit.

Financial Flexibility

In August, 2015, we amended and restated our senior revolving credit facility with Citibank, N.A. and certain other lenders in the amount of $450.0 million, comprised of a $392.0 million revolving loan and $58.0 million term loan (the "Facility"). The Facility has a four year term ending August 19, 2019, 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 credit agreement also provides for, subject to the satisfaction of certain conditions, additional commitments in an amount not to exceed $300.0 million. If additional borrowings are made pursuant to any such additional commitments, the aggregate borrowing limit under the Facility may be increased up to $750.0 million. The 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 credit agreement, which can range from 1.40% to 2.25% for the revolving loan and 1.35% to 2.20% for the term loan. As of June 30, 2016, the margin on our leverage ratio was 1.45% and 1.40% on the revolving and term loans, respectively. We had $300.0 million on the revolving loan and $58.0 million on the term loan totaling $358.0 million in borrowings as of June 30, 2016, with a weighted average interest rate of 1.89%. As of December 31, 2015 we had no borrowings on the revolving loan and $25.0 million in borrowings on the term loan totaling $25.0 million in borrowings.

The 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 it does reduce the borrowing amount available. At June 30, 2016 and December 31, 2015, approximately $4.2 million and $3.4 million of availability was used to back standby letters of credit.

Pursuant to the terms of the 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 Facility are as follows:

Covenant	Must Be	As of June 30, 2016
Maximum Leverage Ratio	<65.0%	41.8%
Minimum Fixed Charge Coverage Ratio	>1.40	2.47
Minimum Tangible Net Worth	2,226,237	3,116,452
Maximum Dividend Payout Ratio	<95.0%	73.5%

Market and Economic Conditions

U.S. rate environment, monetary policy change in China, Japan and Europe, fluctuating oil prices, and turmoil in emerging markets are factors that are influencing financial markets in 2016. Questions still exist on whether the U.S. economy will sustain the growth indicators it has reported and the pace at which the U.S. Federal Reserve will raise interest rates, citing the weakness of the global economy as a reason for greater caution about the prospects for domestic growth. While the U.S. economy looks poised for self-sustaining growth, the global economy is seeing modest improvement led by developed countries. Continued economic uncertainty, both nationally and internationally, causes increased volatility in investor confidence thereby creating similar volatility in the availability of both debt and equity capital. If such volatility is experienced in future periods, our industry, business and results of operations may be adversely impacted.

We anticipate meeting our long-term liquidity requirements, such as scheduled debt maturities, large property acquisitions, and Operating Partnership unit redemptions through the issuance of certain debt or equity securities and/or the collateralization of our properties. At June 30, 2016, we had 148 unencumbered properties with an estimated market value of $453.9 million. Fifty-six of

45

SUN COMMUNITIES, INC.

these unencumbered properties support the borrowing base for our $450.0 million unsecured 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 manufactured housing 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 2015 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, 2016, our net debt to enterprise value approximated 36.6%(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 units to shares of common stock). Our debt has a weighted average maturity of approximately 8.8 years and a weighted average interest rate of 4.7%.

Capital expenditures for the six months ended June 30, 2016 and 2015 included recurring capital expenditures of $8.9 million and $7.7 million, respectively. We are committed to the continued upkeep of our properties and therefore do not expect a decline in our recurring capital expenditures during 2016.

ITEM 3.QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET 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. We generally 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.

We have two interest rate cap agreements with a total notional amount of $160.1 million as of June 30, 2016. The first interest rate cap agreement has a cap rate of 9.00%, a notional amount of $150.1 million and a termination date of April 2018. The second interest rate cap agreement has a cap rate of 11.02%, a notional amount of $10.0 million and a termination date of October 2016.

Our remaining variable rate debt totals $514.9 million and $197.3 million as of June 30, 2016 and 2015, respectively, and bears interest at Prime or various LIBOR rates. If Prime or LIBOR increased or decreased by 1.0%, we believe our interest expense would have increased or decreased by approximately $1.2 million and $0.9 million as of June 30, 2016 and 2015, respectively, based on the $250.0 million and $168.0 million average balances outstanding under our variable rate debt facilities, respectively.

ITEM 4.  CONTROLS AND PROCEDURES

Evaluation of disclosure controls and procedures

Under the supervision and with the participation of our management, including our Chief Executive Officer, Gary A. Shiffman, and Chief Financial Officer, Karen J. Dearing, we evaluated the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this quarterly report, pursuant to Rule 13a-15 of the Exchange Act. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures as of the end of the period covered by this report were effective to ensure that information we are required to disclose in our filings with the SEC under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms, and to ensure that information we are required to disclose in the reports that we file under the Exchange Act is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in internal control over financial reporting

There have been no changes in our internal control over financial reporting during the quarterly period ended June 30, 2016 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION

ITEM 1.  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.

ITEM 1A.  RISK FACTORS

In addition to the other information set forth in this report, you should carefully consider the factors described below and the factors in Part 1, Item 1A., "Risk Factors", in our 2015 Annual Report, which could materially affect our business, financial condition or future results. There have been no material changes to the disclosure on these matters set forth in the 2015 Annual Report.

The intended benefits of the Carefree Communities acquisition may not be realized.

The Carefree Communities acquisition poses risks for our ongoing operations, including, among others:

• that senior management’s attention may be diverted from the management of daily operations to the integration of the properties acquired in the acquisition;

• costs and expenses associated with any undisclosed or potential liabilities;

• that the properties acquired in the acquisition may not perform as well as anticipated; and

48

SUN COMMUNITIES, INC.

• that unforeseen difficulties may arise in integrating the properties acquired in the acquisition into our portfolio.

As a result of the foregoing, we cannot assure you that the Carefree Communities acquisition will be accretive to us in the near term or at all. Furthermore, if we fail to realize the intended benefits of the properties acquired in the acquisition, the market price of our common stock could decline to the extent that the market price reflects those benefits.

ITEM 2.  UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

Issuer Purchases of Equity Securities

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 under this buyback program during the six months ended June 30, 2016.  There is no expiration date specified for the buyback program.

Real Estate Acquisitions

Carefree Acquisition

On June 9, 2016, pursuant to a Stock Purchase Agreement dated March 22, 2016, the Company through the Operating Partnership acquired from Carefree Communities Intermediate Holdings, L.L.C. (the "Seller") all of the issued and outstanding shares of common stock of Carefree Communities Inc. ("Carefree Communities") or ("Carefree"). Carefree Communities directly or indirectly owns 103 manufactured home (“MH”) and recreational vehicle (“RV”) communities, comprising over 27,000 sites.

The aggregate purchase price for the acquisition was $1.68 billion. At the closing, the Company issued the Seller 3,329,880 shares of its common stock (the "Acquisition Shares") at an issuance price of $67.57 per share (or $225.0 million in common stock), and the Operating Partnership paid the balance of the purchase price, or $1.455 billion, in cash. Approximately $1.0 billion of the cash payment was applied simultaneously to pay off debt on the properties owned by Carefree Communities. The Operating Partnership funded the cash portion of the purchase price in part with the proceeds of the Fannie Mae Financing and the NML Financing (See Note 8).

On March 30, 2016, we closed on an underwritten public offering of 6,037,500 shares of common stock at a price of $66.50 per share.   The net proceeds from the offering of $385.4 million were used to fund a portion of the purchase price for the acquisition of the Carefree Communities.

Collateralized Receivables and Transfers of Financial Assets

Transfers and Servicing [Abstract]

Transfers Of Financial Assets

Transfers of Financial Assets

We 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 less than 64	90	%
Equal to or greater than 64 but less 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 $144.0 million (net of allowance of $0.7 million) and $139.8 million (net of allowance of $0.7 million) as of June 30, 2016 and December 31, 2015, respectively. The receivables have a weighted average interest rate and maturity of 10.1% and 15.7 years as of June 30, 2016, and 10.2% and 15.6 years as of December 31, 2015.

The outstanding balance on the secured borrowing was $144.7 million and $140.4 million as of June 30, 2016 and December 31, 2015, 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 $3.4 million and $3.3 million for the three months ended June 30, 2016 and 2015, respectively, and $6.8 million and $6.3 million for the six months endedJune 30, 2016 and 2015, respectively.  

The balances of the collateralized receivables and secured borrowings fluctuate. The balances increase as additional notes receivable are transferred and exchanged for cash proceeds. The balances 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

Consolidated Variable Interest Entities

   Consolidated Variable Interest Entities

In 2016, the Company adopted Accounting Standards Update (“ASU”) No. 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis. The Company evaluated the application of ASU No. 2015-02 and concluded that no change was required to its accounting of its interests in less than wholly owned joint ventures, however, the Operating Partnership now meets the criteria as a variable interest entity. The Company’s significant asset is its investment in the Operating Partnership, and consequently, substantially all of the Company’s assets and liabilities represent those assets and liabilities of the Operating Partnership.

Other VIEs that are consolidated include: Rudgate Village SPE, LLC; Rudgate Clinton SPE, LLC; Rudgate Clinton Estates SPE, LLC (the “Rudgate Borrowers”); and Wildwood Village Mobile Home Park ("Wildwood"). We evaluated our arrangements with these properties under the guidance set forth in FASB Accounting Standard Codification ("ASC") ASC Topic 810 "Consolidation". We concluded that the Rudgate Borrowers and Wildwood qualify as VIEs as we are the primary beneficiary and hold controlling financial interests in these entities due to our power to direct the activities that most significantly impact the economic performance of the entities, as well as our obligation to absorb the most significant losses and our rights to receive significant benefits from these entities. As such, the transactions and accounts of these VIEs are included in the accompanying Consolidated Financial Statements.

The following table summarizes the assets and liabilities included in our Consolidated Balance Sheets after appropriate eliminations have been made (in thousands):

	June 30, 2016			December 31, 2015

Investment property, net and other assets related to the consolidated VIEs comprised approximately 1.6% and 2.3% of our consolidated total assets at June 30, 2016 and December 31, 2015, respectively. Debt and other liabilities comprised approximately 1.8% and 2.5% of our consolidated total liabilities at June 30, 2016 and December 31, 2015, respectively. Noncontrolling interest related to the consolidated VIEs comprised less than 1.0% of our consolidated total equity at June 30, 2016 and December 31, 2015.

Collateralized Term Loans

In June 2016, 17 subsidiaries of the Operating Partnership entered into a Master Credit Facility Agreement (the "Fannie Mae Credit Agreement") with Regions Bank, as lender. Pursuant to the Fannie Mae Credit Agreement, Regions Bank loaned a total of $338.0 million under a senior secured credit facility, comprised of twoten-year term loans in the amount of $300.0 million and $38.0 million, respectively (collectively the "Fannie Mae Financing"). The $300.0 million term loan bears interest at 3.69% per year and the $38.0 million term loan bears interest at 3.67% per year for a blended rate of 3.688% per year. The Fannie Mae Financing provides for principal and interest payments which will be due based on a 30-year amortization.

The Fannie Mae Financing is secured by mortgages encumbering 17 MH communities comprised of real and personal property owned by the borrowers. Additionally, the Company and the Operating Partnership have provided a guaranty of the non-recourse carve-out obligations of the borrowers under the Fannie Mae Financing.

Also in June 2016, three subsidiaries of the Operating Partnership entered into mortgage loan documents (the "NML Loan Documents") with The Northwestern Mutual Life Insurance Company ("NML"). Pursuant to the NML Loan Documents, NML made three portfolio loans to the subsidiary borrowers in the aggregate amount of $405.0 million. NML loaned $162.0 million under a ten-year term loan to two of the subsidiary borrowers (the "Portfolio A Loan"). The Portfolio A Loan bears interest at 3.53% per year and is secured by deeds of trust encumbering seven MH communities and one RV community. NML also loaned $163.0 million under a 12-year term loan (the "Portfolio B Loan") to one subsidiary which is also a borrower under the Portfolio A Loan. The Portfolio B Loan bears interest at 3.71% per year and is secured by deeds of trust and a ground lease encumbering eight MH communities. NML also loaned $80.0 million under a 12-year term loan (the "Portfolio C Loan" and, collectively, with the Portfolio A Loan and the Portfolio B Loan, the "NML Financing") to one subsidiary borrower. The Portfolio C Loan bears interest at 3.71% per year and is secured by a mortgage encumbering one RV community. All of the MH and RV communities that secure the NML Financing were acquired as part of the Carefree Communities acquisition (See Note 2).

The NML Financing is generally non-recourse, however, the borrowers under the NML Financing and the Operating Partnership are responsible for certain customary non-recourse carveouts. In addition, the NML Financing will be fully recourse to the subsidiary borrowers and the Operating Partnership if: (a) the borrowers violate the prohibition on transfer covenants set forth in the loan documents; or (b) a voluntary bankruptcy proceedings is commenced by the borrowers or an involuntary bankruptcy, liquidation, receivership or similar proceeding has commenced against the borrowers and remains undismissed for a period of 90 days.

In March 2015, in relation to the acquisition of Meadowlands, we assumed a $6.3 million mortgage with an interest rate of 6.5% and a remaining term of 6.5 years. Also, in relation to this acquisition, we entered into a note payable with the seller for $2.4 million that bears no interest but is payable in three equal yearly installments beginning in March 2016. During the first half of 2016, we paid the first of the yearly installments of $0.8 million.

The collateralized term loans totaling $2.8 billion as of June 30, 2016, are secured by 189 properties comprised of 75,876 sitesrepresenting approximately $2.7 billion of net book value.

Secured Borrowing

See Note 3, "Collateralized Receivables and Transfers of Financial Assets", for additional information regarding our collateralized receivables and secured borrowing transactions.

Preferred OP Units

Included in preferred OP units is $34.7 million of Aspen preferred OP units issued by the Operating Partnership which, as of June 30, 2016, are convertible indirectly into 495,552 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% 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%. On January 2, 2024, we are required to redeem all Aspen preferred OP units that have not been converted to common OP units.

Lines of Credit

In August, 2015, we amended and restated our senior revolving credit facility with Citibank, N.A. and certain other lenders in the amount of $450.0 million, comprised of a $392.0 million revolving loan and $58.0 million term loan (the "Facility"). The Facility has a four year term ending August 19, 2019, 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 credit agreement also provides for, subject to the satisfaction of certain conditions, additional commitments in an amount not to exceed $300.0 million. If additional borrowings are made pursuant to any such additional commitments, the aggregate borrowing limit under the Facility may be increased up to $750.0 million. The 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 credit agreement, which can range from 1.40% to 2.25% for the revolving loan and 1.35% to 2.20% for the term loan. As of June 30, 2016, the margin on our leverage ratio was 1.45% and 1.40% on the revolving and term loans, respectively. We had $300.0 million on the revolving loan and $58.0 million on the term loan totaling $358.0 million in borrowings as of June 30, 2016, with a weighted average interest rate of 1.89%. As of December 31, 2015 we had no borrowings on the revolving loan and $25.0 million in borrowings on the term loan totaling $25.0 million in borrowings.

The 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, 2016 and December 31, 2015, approximately $4.2 million and $3.4 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%. At June 30, 2016, the effective interest rate was 7.0%.  At June 30, 2016 and December 31, 2015, there was no outstanding balance.

Covenants

Pursuant to the terms of the 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, 2016, we were in compliance with all covenants.

Equity Transactions

Equity and Mezzanine Securities

In June 2015, we entered into an At the Market Offering Sales Agreement (the "Sales Agreement") with BMO Capital Markets Corp., Merrill Lynch, Pierce, Fenner and Smith Incorporated and Citigroup Global Markets Inc. (collectively, the "Sales Agents"). Pursuant to the Sales Agreement, we may offer and sell shares of our common stock, having an aggregate offering price of up to $250.0 million, from time to time through the Sales Agents. Each Sales Agent is entitled to compensation in an agreed amount not to exceed 2.0% of the gross price per share for any shares sold through it from time to time under the Sales Agreement. During the second quarter of 2016, 485,000 shares of common stock were issued at the prevailing market price of our common stock at the time of each sale with a weighted average sales price of $71.86, and we received net proceeds of approximately $34.4 million.

In March 2016, we closed an underwritten registered public offering of 6,037,500 shares of common stock at a price of $66.50 per share. Net proceeds from the offering were approximately $385.4 million after deducting discounts and expenses related to the offering, which we used to fund a portion of the purchase price for the acquisition of Carefree Communities.

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 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 under this buyback program during the six months ended June 30, 2016 or 2015. There is no expiration date specified for the buyback program.

Subject to certain limitations, common OP unit holders can convert their common OP units into an equivalent number of shares of common stock at any time. During the six months ended June 30, 2016 and 2015, there were 0 and 17,500 common OP units converted to shares of common stock, respectively.

Subject to certain limitations, Series A-1 preferred OP unit holders may convert each Series A-1 preferred OP units to approximately 2.439 shares of our common stock at any time. During the six months ended June 30, 2016 and 2015, holders of Series A-1 preferred OP units converted 9,730 units into 23,729 shares of common stock, and 37,885 units into 92,398 shares of common stock, respectively.

Subject to certain limitations, Series A-4 preferred OP unit holders may convert each Series A-4 preferred OP units to approximately 0.444 shares of our common stock at any time. During the six months ended June 30, 2016, holders of Series A-4 preferred OP units converted 7,000 units into 3,110 shares of common stock. No such units were converted during the six months ended June 30, 2015.

Cash distributions of $0.65 per share were declared for the quarter ended June 30, 2016. On July 15, 2016, cash payments of approximately $46.5 million for aggregate distributions were made to common stockholders, common OP unit holders and restricted stockholders of record as of June 30, 2016. Cash distributions of $0.45 per share were declared on our Series A cumulative redeemable preferred stock for the quarter ended June 30, 2016. On July 15, 2016, cash payments of approximately $1.5 million for aggregate distributions were made to Series A cumulative redeemable preferred stockholders of record as of June 30, 2016. In addition, cash distributions of $0.41 per share were declared on our Series A-4 Preferred Stock for the quarter ended June 30, 2016. On June 30, 2016, cash payments of approximately $0.7 million were made to Series A-4 Preferred Stock stockholders of record as of June 17, 2016.

Share-Based Compensation

Share-Based Compensation

During the three months ended June 30, 2016, we granted 76,000 shares of restricted stock to key employees under the Sun Communities Inc. 2015 Equity Incentive Plan. The shares had a fair value of $69.53 per share and will vest as follows: April 18, 2019: 35%, April 18, 2020: 35%, April 18, 2021: 20%, April 18, 2022: 5%, and April 18, 2023: 5%. The fair value of issued grants was determined by using the closing price of our common stock on the date the shares were issued.

During the three months ended March 31, 2016, we granted 16,800 shares of restricted stock to our non-employee directors under our First Amended and Restated 2004 Non-Employee Director Option Plan. The awards vest on March 15, 2019, and had a fair value of $69.45 per share. The fair value was determined by using the closing share price of our common stock on the date the shares were issued.

During the three months ended March 31, 2016, we granted 130,000 shares of restricted stock to our executive officers under the Sun Communities, Inc. 2015 Equity Incentive Plan. The shares had a fair value of $69.25 per share. Half of the shares will vest as follows: March 20, 2019: 20%; March 20, 2020, 30%; March 20, 2021, 35%; March 20, 2022, 10%; and March 20, 2023, 5%. The remaining 65,000 shares are subject to market and performance conditions with multiple tranches that vest through March 2022. Share-based compensation for restricted stock awards with performance 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.

During the six months ended June 30, 2016 and 2015, 9,349 and 4,084 shares of common stock, respectively, were issued in connection with the exercise of stock options, and the net proceeds received during both periods was $0.1 million.

The vesting requirements for 146,765 restricted shares granted to our executives and employees were satisfied during the six months ended June 30, 2016.

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, and develops MH communities and RV communities and is in the business of acquiring, operating, and expanding MH and RV communities.  The Home Sales and Rentals segment offers manufactured home 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 $60.2 million annually. This transient RV revenue was recognized 16.9% and 18.1% in the first and second quarters, respectively, and is expected to be 45.3% and 19.7% in the third and fourth quarters, respectively. In 2015, transient revenue was $39.7 million. We recognized 22.5% in the first quarter, 17.7% in the second quarter, 45.2% in the third quarter, and 14.6% in the fourth quarter.

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

Income Taxes

Income Taxes

We and Carefree Communities, Inc have each elected to be taxed as a real estate investment trust (“REIT”) pursuant to Section 856(c) of the Internal Revenue Code of 1986 (“Code”), as amended. In order for us to qualify as a REIT, at least 95% of our gross income in any year must be derived from qualifying sources. In addition, a REIT must distribute annually at least 90% of its REIT ordinary taxable income to its stockholders and meet other tests.

Qualification as a REIT involves the satisfaction of numerous requirements (some on an annual and quarterly basis) established under highly technical and complex Code provisions for which there are only 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, 2016.

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, U.S. federal income taxes and excise taxes on our undistributed income.

Our various taxable REIT subsidiaries are subject to U.S. federal income taxes. Due to the Carefree acquisition, certain of our properties are also subject to Canadian income taxes. Our 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 and depreciation. Full valuation allowances are generally recorded against all U.S. federal deferred tax assets. For Canadian purposes, a minimal amount of deferred tax asset is recorded in relation to a corporate entity and included in “Other assets, net” in our Consolidated Balance Sheets as of June 30, 2016. No federal deferred tax asset is included in "Other assets, net," in our Consolidated Balance Sheets as of June 30, 2016 and December 31, 2015.

We had no unrecognized tax benefits as of June 30, 2016 and 2015. We expect no significant increases or decreases in unrecognized tax benefits due to changes in tax positions within one year of June 30, 2016.

We recorded a provision for federal, state, and Canadian income taxes of approximately $0.1 million and $0.1 million for the three months ended June 30, 2016, and 2015, respectively, and $0.3 million and $0.2 million for the six months ended June 30, 2016 and 2015, respectively.

Derivative Instruments And Hedging Activities

Derivative Instruments and Hedging Activities

Our objective in using interest rate derivatives is to manage exposure to interest rate movements thereby minimizing the effect of interest rate changes and the effect it could have on future cash flows. Interest rate caps are used to accomplish this objective. We do not enter into derivative instruments for speculative purposes nor do we have any swaps in a hedging arrangement.

The following table provides the terms of our interestrate derivative contracts that were in effect as of June 30, 2016:

Type	Purpose	Effective Date	Maturity Date	Notional  (in millions)		Based on	Variable Rate	Fixed Rate	Spread	Effective Fixed Rate

In accordance with ASC Topic 815, "Derivatives and Hedging"("ASC 815"), derivative instruments are recorded at fair value in "Other assets, net" or "Other liabilities" on the Consolidated Balance Sheet. As of June 30, 2016 and December 31, 2015, the fair value of the derivatives was zero.

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" ("ASC 820"), requires disclosure about how fair value is determined 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.

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:

Derivative Instruments

The derivative instruments held by us are interest rate cap agreements for which quoted market prices are indirectly available. For those derivatives, we use model-derived valuations in which all significant inputs and significant value drivers are observable in active markets provided by brokers or dealers to determine the fair value of derivative instruments on a recurring basis (Level 2). See Note 14 for Derivative Instruments.

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). See Note 4 for Installment Notes Receivable.

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). See Note 8 for Long-Term 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). See Note 3 for Collateralized Receivables and Secured Borrowing.

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 their fair values on a recurring basis as of June 30, 2016. The table presents the carrying values and fair values of our financial instruments as of June 30, 2016 and December 31, 2015 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 because the carrying values associated with these instruments approximate fair value since their maturities are less than one year.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In March 2016, the FASB issued ASU 2016-09 "Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting". ASU 2016-09 is intended to simplify several aspects of the accounting for share-based payments. The guidance will be effective for fiscal years beginning after December 15, 2016, including interim periods within that year. The Company is in the process of evaluating the impact of the adoption of this ASU.

In February 2016, the FASB issued ASU 2016-02 "Leases (Topic 842)". The core principle of Topic 842 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. The Company is currently evaluating the impact of the adoption of this new standard.

In April 2015, the FASB issued ASU 2015-03 "Interest - Imputation of Interest (Subtopic 835-30) Simplifying the Presentation of Debt Issuance Costs" ("ASU 2015-03"). This amendment requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. In August 2015, the FASB issued ASU 2015-15 "Interest - Imputation of Interest (Subtopic 835-30) Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements" ("ASU 2015-15"). This amendment provides additional guidance within ASU 2015-03 for debt issuance costs related to line of credit arrangements. These amendments are effective for fiscal years beginning after December 15, 2015, and interim periods within those years, with early adoption permitted. Entities should apply the amendments retrospectively. ASU 2015-15 provides commentary that the SEC staff would not object to an entity deferring and presenting costs associated with line of credit arrangements as an asset and subsequently amortizing them ratably over the term of the revolving debt arrangement. We adopted these amendments as of March 31, 2016, which resulted in a reclassifying of deferred financing costs of $8.2 million from "Other assets, net" to "Mortgage loans payable" on the Consolidated Balance Sheets as of March 31, 2016. The debt issuance costs related to our line of credit facility remain classified as an asset on the Consolidated Balance Sheets. This change was applied throughout this document where applicable.

In February 2015, the FASB issued ASU No. 2015-02 "Consolidation (Topic 810) Amendments to the Consolidation Analysis" ("ASU 2015-02") which modified the evaluation of whether limited partnerships and similar legal entities are variable interest entities or voting interest entities. All entities are subject to reevaluation under the revised consolidation model. The Company is the sole general partner in a limited partnership, and as such, the Company has complete control in conducting all business activities associated with the Partnership. Limited partners do not have kickout rights or participating rights. The Company adopted ASU 2015-02 as of March 31, 2016 and fully consolidates the activities of the Operating Partnership within its Consolidated Financial Statements under the variable interest entity model as it is the primary beneficiary. There was no impact to the Consolidated Financial Statements as the Company previously consolidated under the voting interest entity model.

In May 2014, the FASB issued ASU 2014-09 "Revenue from Contracts with Customers (Topic 606)" ("ASU 2014-09"). The objective of this amendment is to establish a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will supersede most of the existing revenue recognition guidance, including industry-specific guidance. The core principle is that a company 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. In applying this amendment, companies will perform a five-step analysis of transactions to determine when and how revenue is recognized. This amendment applies to all contracts with customers except those that are within the scope of other topics in the FASB ASC. This amendment is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period; early adoption is not permitted. An entity should apply the amendments using either the full retrospective approach or retrospectively with a cumulative effect of initially applying the amendments recognized at the date of initial application. We are currently evaluating the methods of adoption and the impact that the adoption of ASU 2014-09 may have on our Consolidated Financial Statements.
