1.      Basis of Presentation

The unaudited interim consolidated financial statements of 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”), SunChamp LLC (“SunChamp”), and Sun Home Services, Inc. (“SHS”), have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial information and in accordance with accounting principles generally accepted in the United States of America (“GAAP”). Certain information and footnote disclosures required for annual financial statements have been condensed or excluded pursuant to SEC rules and regulations. Accordingly, the interim financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. The accompanying 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.

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 interim 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, 2013 as filed with the SEC on February 20, 2014 (the “2013 Annual Report”). These statements have been prepared on a basis that is substantially consistent with the accounting principles applied in our 2013 Annual Report.

2.      Real Estate Acquisitions and Dispositions

Green Courte Real Estate Partners, LLC

In July 2014, we entered into agreements to acquire a portfolio of manufactured home communities from Green Courte Real Estate Partners, LLC sponsored funds (the "Green Courte Entities"). The portfolio consists of 59 manufactured home communities comprising over 19,000 sites in eleven states, including nearly 11,000 sites located in Florida. Approximately 14,000 sites, or 71%, of the portfolio is included in age-restricted communities. In connection with this transaction, the Company will assume the Green Courte Entities' right to acquire an additional manufactured home community pursuant to a binding purchase agreement.

Total consideration for the acquisition is approximately $1.32 billion, including the assumption of approximately $560 million of debt. We will pay approximately $311 million in cash (increased by the reduction in assumed mortgage debt prior to closing), issue approximately $262 million of common stock and common OP units, and issue $175 million of newly-created Series A-4 Convertible Perpetual Preferred Stock or Convertible Perpetual Preferred Operating Limited Partnership units to the Green Courte Entities. Additionally, an affiliate of the Green Courte Entities has committed to make an investment of not less than approximately $13 million in the Company’s equity.

Subject to certain conditions, we anticipate that the acquisition will occur in two separate closings. The closing with respect to 34 communities is anticipated to occur 10 business days after the loan assumption approval is obtained for a sufficient number of communities as set forth in the acquisition agreements, but not later than December 31, 2014 (or such earlier date as we determine upon notice to the Green Courte Entities). The closing with respect to the remaining 25 communities is anticipated to occur on January 6, 2015. The consummation of the acquisition is subject to certain confirmatory diligence and customary closing conditions, including obtaining certain third party consents. As a result, there can be no assurances as to the actual closings or the timing of either of the closings.

Pursuant to the acquisition agreements, we made an earnest money deposit in the aggregate amount of $50 million (“Earnest Money Deposit”). The Earnest Money Deposit may be forfeited if we fail to close on the transactions contemplated by any definitive agreement in breach of the terms thereof and such breach continues for a period of 10 days without cure. The Earnest Money Deposit is the sole remedy for any such breach and shall serve as liquidated damages, except that if such a default occurs after the first closing, we shall also pay the Green Courte Entities the sum of $25 million as additional liquidated damages.

Acquisitions

In June 2014, we acquired Lake Rudolph Campground and Recreational Vehicle Resort ("Lake Rudolph"), a recreational vehicle ("RV") community with 503 sites located in Santa Claus, Indiana.

In April 2014, we acquired Saco/Old Orchard Beach RV Resort ("Saco"), a community with 127 sites located in Saco, Maine.

In February 2014, we acquired Driftwood Camping Resort ("Driftwood"), an RV community with 698 sites and expansion potential of approximately 30 sites located in Clermont, New Jersey, and Seashore Campsites RV and Campground ("Seashore"), an RV community with 685 sites located in Cape May, New Jersey.

In January 2014, we acquired Castaways RV Resort & Campground ("Castaways"), an RV community with 369 sites and expansion potential of approximately 25 sites located in Worcester County, Maryland, and Wine Country RV Resort ("Wine Country"), an RV community with 166 sites and expansion potential of approximately 34 sites located in Paso Robles, California.

Dispositions

During the nine months ended September 30, 2014, we closed on the sales of 10 manufactured housing ("MH") communities: Bedford Hills, White Oak, Falcon Pointe, Timberbrook, Woodlake Estates, Byrne Hill, Continental Estates, Davison East, Countryside Village and Desert View Village. During the first quarter of 2014, the Company chose to early adopt Accounting Standards Update ("ASU") 2014-08, "Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity" ("ASU 2014-08"). Pursuant to ASU 2014-08, the disposals of the communities do not qualify for presentation as discontinued operations, as the sales do not have a major impact on our operations and financial results and do not represent a strategic shift. Additionally, the communities are not considered individually significant components and therefore do not qualify for presentation as discontinued operations. A gain of $14.5 million is recorded in "Gain on disposition of properties, net" in our consolidated statement of operations.

3.      Investment Property

The following table sets forth certain information regarding investment property (in thousands):

	September 30, 2014			December 31, 2013
Land	$	216,276		$	194,404

Accumulated depreciation	(760,480		)	(734,067		)
Investment property, net	$	1,884,632		$	1,755,052

Land improvements and buildings consist primarily of infrastructure, roads, landscaping, clubhouses, maintenance buildings and amenities.

In September 2014, we recorded impairment charges of $0.8 million associated with a long-lived asset for an MH and RV community located in La Feria, Texas. This community consists of 280 developed sites. Circumstances that prompted this test of recoverability included a decrease in net operating income and the overall operating performance of the community. We recognized the impairment loss because the long-lived asset's carrying value was deemed not recoverable and exceeded the estimated fair value. We estimated the fair value of the long-lived asset based on discounted future cash flows and any potential disposition proceeds for the asset. The impairment loss is recorded in "Asset impairment charge" on our consolidated statements of operations.

See Note 2, "Real Estate Acquisitions and Dispositions", for details on recent acquisitions and dispositions.

4.      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. 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 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 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.  The percentage used to determine the repurchase price of the outstanding principal balance on the installment note is based on the number of payments made on the note. In general, the repurchase price is determined as follows:

Number of Payments	Repurchase %
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 in Notes and Other Receivables (see Note 5), and the cash proceeds received from these transactions have been classified as a secured borrowing in Debt (see Note 9) within the consolidated balance sheets. The balance of the collateralized receivables was $117.5 million (net of allowance of $0.8 million) and $109.8 million (net of allowance of $0.7 million) as of September 30, 2014 and December 31, 2013, respectively.  The outstanding balance on the secured borrowing was $118.2 million and $110.5 million as of September 30, 2014 and December 31, 2013, 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):

	Nine Months Ended
	September 30, 2014
Beginning balance	$	110,510
Financed sales of manufactured homes	24,840
Principal payments and payoffs from our customers	(9,723		)
Principal reduction from repurchased homes	(7,397		)
Total activity	7,720
Ending balance	$	118,230

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 $3.0 million and $2.7 million and $8.6 million and $7.7 million for the three and nine months endedSeptember 30, 2014 and 2013, respectively.

Origen Financial Services, LLC (“OFS LLC”)

At September 30, 2014 and 2013, 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 own 5,000,000 shares of common stock of Origen which approximates an ownership interest of 19%. Although it is no longer originating or servicing loans, Origen continues to manage an existing portfolio of manufactured home loans and asset backed securities. We have suspended equity accounting for this investment as the carrying value of our investment is zero. We do, however, receive income from distributions on our shares of Origen common stock.  Our investment in Origen had a market value of approximately $8.4 million based on a quoted market closing price of $1.68 per share from the OTC Pink Marketplace as of September 30, 2014.

In September 2014, Origen announced that it has entered into an agreement to sell substantially all of its assets to an affiliate of GoldenTree Asset Management LP. Contingent upon the closing of the sale, Origen plans to dissolve and liquidate. The sale is pending stockholder approval.

Variable interest entities ("VIEs") that are consolidated include Rudgate Village SPE, LLC, Rudgate Clinton SPE, LLC and Rudgate Clinton Estates SPE, LLC (the “Rudgate Borrowers”). We concluded that the Rudgate Borrowers qualify as VIEs as we are the primary beneficiary and hold a controlling financial interest 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.

Additionally, in July and August 2014, we borrowed the aggregate amount of $63.5 million under five mortgage loans from Ladder Capital Finance, LLC ("Ladder"). The loans have a ten year term and a blended annual interest rate of 4.56%. The proceeds of the loans were used to pay down a portion of our senior secured line of credit.

In January 2014, we and four of our subsidiaries borrowed the aggregate amount of $99.0 million under four mortgage loans (each, an “Individual Loan” and, together, the “Loan”) from The Northwestern Mutual Life Insurance Company (“NM”) pursuant to a Master Loan Agreement with NM. Each Individual Loan accrues interest at a rate of 4.20% and matures on February 13, 2026. We and each of the four borrowers have guaranteed the Loan. The proceeds of the Loan were used to repay a portion of our senior secured line of credit.

The collateralized term loans totaling $1.1 billion as of September 30, 2014, are secured by 101 properties comprised of 39,997 sites representing approximately $746.0 million of net book value.

Aspen Preferred OP Units

The Aspen preferred OP units issued by the Operating Partnership are convertible into 526,212 shares of the Company's common stock based on a conversion price of $68 per share with a redemption date of January 1, 2024. The current preferred rate is 6.5%.

Secured Borrowing

See Note 4, "Transfers of Financial Assets", for additional information regarding our collateralized receivables and secured borrowing transactions.

Mortgage Notes

In September 2014, we paid in full the $13.5 million mortgage agreement secured by Cave Creek and Pine Trace. We also paid off the $2.4 million mortgage agreement secured by Brookside Village upon maturity.

In August 2014, we paid in full the entire $6.5 million mortgage agreement secured by Sheffield Estates upon maturity.

The mortgage notes totaling $118.0 million as of September 30, 2014, are collateralized by 14 properties comprised of 6,659 sites representing approximately $194.1 million of net book value.

Lines of Credit

We have a senior secured revolving credit facility with Citibank, N.A. and certain other lenders in the amount of $350.0 million (the "Facility"). The Facility has a four year term ending May 15, 2017, which can be extended for one additional year 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 $250.0 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 1.65% to 2.90%. Based on our calculation of the leverage ratio as of September 30, 2014, the margin was 1.65%. At September 30, 2014 we had no amount outstanding under the Facility and at December 31, 2013, we had approximately $178.1 million outstanding under the Facility. At September 30, 2014 and December 31, 2013, approximately $3.2 million and $2.7 million, respectively, of availability was used to back standby letters of credit.

The Facility is secured by a first priority lien on all of our equity interests in each entity that owns all or a portion of the properties constituting the borrowing base and collateral assignments of our senior and junior debt positions in certain borrowing base properties.

We also have a $20.0 million secured line of credit agreement collateralized by a portion of our rental home portfolio. The net book value of the rental homes pledged as security for the loan must meet or exceed 200% of the outstanding loan balance. The

terms of the agreement require interest only payments for the first five years, with the remainder of the term being amortized based on a 10 year term. The interest rate is the prime rate as published in the Wall Street Journal adjusted the first day of each calendar month plus 200 basis points with a minimum rate of 5.5%. At both September 30, 2014 and December 31, 2013, the effective interest rate was 5.5%, and there was no amount outstanding.

We have a $12.0 million manufactured home floor plan facility renewable indefinitely until our lender provides us 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 September 30, 2014, the effective interest rate was 7.0%.  The outstanding balance was zero and $3.3 million at September 30, 2014 and December 31, 2013, respectively.

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 September 30, 2014, we were in compliance with all covenants.

10.      Equity Transactions

In September 2014, we closed an underwritten registered public offering of 6,900,000 shares of common stock at a price of $50.60 per share, which includes 900,000 shares sold to the underwriter pursuant to the full exercise of its option to purchase additional shares. Net proceeds from the offering were approximately $348.9 million after deducting expenses related to the offering. We intend to use the majority of the net proceeds of the offering to fund the cash portion of the purchase price for the previously-announced acquisition of MH communities from the Green Courte Entities (see Note 2) and use the remainder of the net proceeds from the offering to repay borrowings outstanding under the Facility. The consummation of the acquisition is subject to certain confirmatory diligence and customary closing conditions, including obtaining third party consents. If for any reason the acquisition is not consummated, we intend to use the net proceeds from the offering to repay borrowings outstanding under the Facility, fund possible future acquisitions of properties and for working capital and general corporate purposes.

In March 2014, we closed an underwritten registered public offering of 4,200,000 shares of common stock at a price of $44.45 per share, and in April 2014, the underwriters exercised their option to purchase an additional 630,000 shares of common stock at a price of $44.45 less the declared dividend of $0.65 per share. Net proceeds from the offering were $214.0 million after deducting underwriting discounts and the expenses related to the offering. We used the net proceeds of the offering to repay borrowings outstanding under the Facility, for acquisitions of properties and for working capital and general corporate purposes.

In November 2004, our Board of Directors authorized us to repurchase up to 1,000,000 shares of our common stock.  We have 400,000 common shares remaining in the repurchase program.  No common shares were repurchased during the nine months ended September 30, 2014 or 2013.  There is no expiration date specified for the buyback program.

Common OP unit holders can convert their common OP units into an equivalent number of shares of common stock at any time.  During the nine months ended September 30, 2014 and 2013, there were no common OP units converted to shares of common stock.

Subject to certain limitations, Series A-1 preferred OP unit holders may convert their Series A-1 preferred OP units to shares of our common stock at any time. During the nine months ended September 30, 2014, holders of Series A-1 preferred OP units converted 18,773 units to 45,785 shares of common stock. No such units were converted during the nine months ended September 30, 2013.

Cash distributions of $0.65 per share were declared for the quarter ended September 30, 2014. On October 17, 2014, cash payments of approximately $32.6 million for aggregate distributions were made to common stockholders, common OP unitholders and restricted stockholders of record as of September 30, 2014. In addition, cash distributions of $0.4453 per share were declared on the Company's Series A cumulative redeemable preferred stock. On October 15, 2014, cash payments of approximately $1.5 million for aggregate distributions were made to Series A cumulative redeemable preferred stockholders of record as of October 1, 2014.

In July 2014, the Company and Gary A. Shiffman (the Company's Chairman and Chief Executive Officer) entered into an Amended and Restated Restricted Stock Award Agreement, which amended and restated in its entirety the Restricted Stock Award Agreement dated June 20, 2013 between the Company and Mr. Shiffman. Under the original stock award agreement, the Company granted Mr. Shiffman 250,000 restricted shares of the Company's common stock, of which 175,000 restricted shares were awarded in respect of the performance of Mr. Shiffman and the Company over the prior three years and 75,000 restricted shares were awarded to induce Mr. Shiffman to execute a new five-year employment agreement. All of these restricted shares were scheduled to vest over time through June 2020. The restated stock award agreement amended the vesting schedule of the restricted shares, of which 100,000 restricted shares are now subject to performance vesting and the remaining 150,000 shares will vest over time through June 2020.

In July 2014, we granted 3,500 shares of restricted stock to an employee under our Sun Communities Inc. Equity Incentive Plan ("2009 Equity Plan").

In February 2014, we granted 14,000 shares of restricted stock to our directors under our First Amended and Restated 2004 Non-Employee Director Option Plan. The awards vest on February 12, 2017, and had a fair value of $48.01 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 nine months ended September 30, 2014, 4,904 shares of common stock were issued in connection with the exercise of stock options and the net proceeds received were $0.1 million.

12. Segment Reporting

We group our operating segments into reportable segments that provide similar products and services. Each operating segment has discrete financial information evaluated regularly by the Company's 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 Real Property Operations’ revenues and is expected to approximate $31.7 million annually. This transient revenue was recognized 25.2%, 18.2% and 43.2% in the first, second and third quarters, respectively, and is expected to be recognized 13.4% in the fourth quarter of 2014. In 2013, transient revenue was $17.4 million and was recognized 40.0% in the first quarter, 15.0% in the second quarter, 30.0% in the third quarter and 15.0% in the fourth quarter.

13.    Income Taxes

We have elected to be taxed as a real estate investment trust (“REIT”) as defined under Section 856(c) of the Internal Revenue Code of 1986 (“Code”), as amended. In order for us to qualify as a REIT, at least ninety-five percent (95%) of our gross income in any year must be derived from qualifying sources. In addition, a REIT must distribute at least ninety percent (90%) of its REIT ordinary taxable income to its stockholders.

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 September 30, 2014.

As a REIT, we generally will not be subject to 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 and to U.S. federal income and excise taxes on our undistributed income.

SHS, our taxable REIT subsidiary, is subject to U.S. federal 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. A federal deferred tax asset of $1.0 million is included in other assets in our consolidated balance sheets as of September 30, 2014 and December 31, 2013.

We had no unrecognized tax benefits as of September 30, 2014 and 2013. We expect no significant increases or decreases in unrecognized tax benefits due to changes in tax positions within one year of September 30, 2014.

We classify certain state taxes as income taxes for financial reporting purposes. We record Texas Margin Tax as income tax in our financial statements, and we recorded a provision for state income taxes of approximately $0.1 million for the three months ended September 30, 2014 and 2013, and $0.2 million for the nine months ended September 30, 2014 and 2013.

14.    Earnings Per Share

We have outstanding stock options and unvested restricted shares, and our Operating Partnership has outstanding common OP units, convertible A-1 preferred OP units, convertible A-3 preferred OP units and Aspen preferred OP Units, which, if converted or exercised, will impact dilution. 

Computations of basic and diluted earnings per share from continuing operations were as follows (in thousands, except per share data):

15. 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 swaps and caps are used to accomplish this objective. We require hedging derivative instruments to be highly effective in reducing the risk exposure that they are designated to hedge. We formally designate any instrument that meets these hedging criteria as a hedge at the inception of the derivative contract. We do not enter into derivative instruments for speculative purposes.

The following table provides the terms of our interestrate derivative contracts that were in effect as of September 30, 2014:

Type	Purpose	Effective Date	Maturity Date	Notional  (in millions)		Based on	Variable Rate	Fixed Rate	Spread	Effective Fixed Rate
Cap	Cap Floating Rate	4/1/2012	4/1/2015	$	152.4	3 Month LIBOR	0.2310%	11.2650%	—%	N/A
Cap	Cap Floating Rate	10/3/2011	10/3/2016	$	10.0	3 Month LIBOR	0.2310%	11.0200%	—%	N/A

In January 2014, our interest rate swap agreement with a notional amount of $20.0 million expired. We did not enter into a new interest rate swap agreement.

In accordance with ASC Topic 815, Derivatives and Hedging, we have recorded the fair value of our derivative instruments designated as cash flow hedges on the balance sheet. See Note 16 for information on the determination of fair value for the derivative instruments.  The following table summarizes the fair value of derivative instruments included in our consolidated balance sheets as of September 30, 2014 and December 31, 2013 (in thousands):

	Asset Derivatives					Liability Derivatives
	Balance Sheet Location	Fair Value				Balance Sheet Location	Fair Value
Derivatives designated as hedging instruments		September 30, 2014		December 31, 2013			September 30, 2014		December 31, 2013
Interest rate swaps and cap agreement	Other assets	$	—	$	—	Other liabilities	$	—	$	97
Total derivatives designated as hedging instruments		$	—	$	—		$	—	$	97

These valuation adjustments will only be realized under certain situations. For example, if we terminate contracts prior to maturity or if derivatives fail to qualify for hedge accounting, we would need to amortize amounts currently included in accumulated other comprehensive income into interest expense over the terms of the derivative contracts.  We did not terminate our swap prior to maturity, and it did not fail to qualify for hedge accounting; therefore, the net of valuation adjustments through the maturity date approximated zero.

Our hedges were highly effective and had minimal effect on income.  The following tables summarize the impact of derivative instruments for the three and nine months ended September 30, 2014 and 2013 as recorded in the consolidated statements of operations (in thousands):

Derivatives in Cash Flow Hedging	Amount of Gain or (Loss) Recognized in OCI (Effective Portion)				Location of Gain or (Loss) Reclassified from Accumulated OCI into Income (Effective Portion)	Amount of Gain or (Loss) Reclassified from Accumulated OCI into Income (Effective Portion)

Our financial derivative instruments are designated and qualify as cash flow hedges and the effective portion of the gain or loss on such hedges are reported as a component of accumulated other comprehensive income in our consolidated balance sheets.

To the extent that the hedging relationship is not effective or does not qualify as a cash flow hedge, the ineffective portion is recorded in interest expense. Hedges that received designated hedge accounting treatment are evaluated for effectiveness at the time that they are designated as well as through the hedging period. No gain or loss was recognized in the consolidated financial

statements related to hedge ineffectiveness or to amounts excluded from effectiveness testing on our cash flow hedge during the three and nine months ended September 30, 2014 and 2013.

Certain of our derivative instruments contain provisions that require us to provide ongoing collateralization on derivative instruments in a liability position.  As of December 31, 2013, we had collateral deposits recorded in other assets of approximately $0.7 million. As of September 30, 2014, we had no such deposits recorded.

16.    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, establishes a fair value hierarchy that requires the use of observable market data, when available, and prioritizes the inputs to valuation techniques used to measure fair value in the following categories:

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 observable inputs and significant value drivers are observable in active markets.

Level 3—Model derived valuations in which one or more significant inputs or significant value drivers are unobservable, including assumptions developed by us.

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 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 observable inputs and significant value drivers are observable in active markets provided by brokers or dealers to determine the fair values of derivative instruments on a recurring basis (Level 2). See Note 15 for Derivative Instruments.

Installment Notes on Manufactured Homes

The net carrying value of the installment notes 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 5 for Installment Notes.

25

SUN COMMUNITIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

16.   Fair Value of Financial Instruments, continued

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 and rates currently prevailing for comparable loans and instruments of comparable maturities (Level 2). See Note 9 for Long-Term Debt and Lines of Credit.

Collateralized Receivables and Secured Borrowing

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 in 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 4 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 and presents the carrying values and fair values as of September 30, 2014 and December 31, 2013 that were measured using the valuation techniques described above. 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.

	September 30, 2014				December 31, 2013
Financial assets	Carrying Value		Fair Value		Carrying Value		Fair Value
Installment notes on manufactured homes, net	$	21,684	$	21,684	$	25,471	$	25,471

Lines of credit	$	—	$	—	$	181,383	$	181,383

The derivative instruments are the only financial liabilities that were required to be carried at fair value in the consolidated balance sheets for the periods indicated, and we have no financial assets that are required to be carried at fair value.

17.    Recent Accounting Pronouncements

In August 2014, the Financial Accounting Standards Board (the “FASB”) issued ASU No. 2014-15, (“ASU 2014-15”), “Disclosure of Uncertainties About an Entity’s Ability to Continue as a Going Concern”. ASU 2014-15 requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of the date the financial statements are issued and provides guidance on determining when and how to disclose going concern uncertainties in the financial statements. Certain disclosures will be required if conditions give rise to substantial doubt about an entity’s ability to continue as a going concern. ASU 2014-15 applies to all entities and is effective for annual and interim reporting periods ending after December 15, 2016, with early adoption permitted. We are currently evaluating the potential impacts the new standard will have on our quarterly reporting process.

In May 2014, the FASB issued ASU No. 2014-09, (“ASU 2014-09”), “Revenue from Contracts with Customers” as a new Topic, Accounting Standards Codification ("ASC") Topic 606. The objective of ASU 2014-19 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 the new standard, companies will perform a five-step analysis of transactions to determine when and how revenue is recognized. ASU 2014-09 applies to all contracts with customers except those that are within the scope of other topics in the FASB ASC. This ASU is effective for annual reporting periods (including interim periods within those periods) beginning after December 15, 2016 and shall be applied using either a full retrospective or

modified retrospective approach. Early adoption is not permitted. We are currently evaluating the new guidance and have not determined the impact this standard may have on our consolidated financial statements nor decided upon the method of adoption.

In April 2014, the FASB issued ASU No. 2014-08, "Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity" ("ASU 2014-08"). ASU 2014-08 raises the threshold for a disposal to qualify as a discontinued operation by requiring only those disposals of a component or group of components that represent a strategic shift or that will have a major effect on the Company’s operational and financial results and also requires new disclosures of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation. The guidance does not change the presentation requirements for discontinued operations in the statement where net income is presented. ASU 2014-08 also requires the reclassification of assets and liabilities of a discontinued operation in the statement of financial position for all prior periods presented. The standard expands the disclosures for discontinued operations and requires new disclosures related to individually material disposals that do not meet the definition of a discontinued operation, an entity's continuing involvement with a discontinued operation following the disposal date and retained equity method investments in a discontinued operation. ASU 2014-08 is effective for annual periods beginning on or after December 15, 2014 and interim periods within annual periods beginning on or after December 15, 2015. Early adoption is permitted but only for disposals (or classifications as held for sale) that have not been reported in financial statements previously issued or available for issue. We have chosen to early adopt this pronouncement and have applied the guidance to recent applicable disposals (see Note 2).

18.   Commitments and Contingencies

On June 4, 2010, we settled all of the claims arising out of the litigation filed in 2004 by TJ Holdings, LLC in the Superior Court of Guilford County, North Carolina and the associated arbitration proceeding commenced by TJ Holdings in Southfield, Michigan. Under the terms of the settlement agreement, in which neither party admitted any liability whatsoever, we paid TJ Holdings $360,000. In addition, pursuant to this settlement, TJ Holdings’ percentage ownership interest in Sun/Forest, LLC will be increased on a one time basis, in the event of a sale or refinance of all of the SunChamp Properties, to between 9.03% and 28.99% depending on our average closing stock price as reported by the NYSE during the 30 days preceding the sale or refinance of all the SunChamp Properties. Once this percentage ownership interest has been adjusted, there will be no further adjustments from subsequent sales or refinances of the SunChamp Properties. The likelihood of a sale or refinancing of all of the SunChamp properties is not probable as these properties continue to see growth potential nor do we have a need to refinance all of the properties, so we do not expect it to have a material adverse impact on our results of operations or financial condition.

We are involved in various other 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.

19. Subsequent Events

We have evaluated our financial statements for subsequent events through the date that this Form 10-Q was issued.

Settlement Agreement

In October 2014, we entered into a settlement agreement with Robert C. Morgan, Robert Moser and the selling entities of each of the 10 RV communities that we acquired in February 2013. The settlement was related to various warranties, representations and indemnities included in the agreements under which we acquired the RV communities, including a covenant made by the sellers related to the 2012 revenue of the acquired properties. A gain of approximately $4.5 million will be recorded in the fourth quarter of 2014.

Share-based Compensation

In October 2014, we granted 8,000 shares of restricted stock to employees under our 2009 Equity Plan. The restricted shares had a fair value of $54.26 per share and will vest as follows: October 21, 2017: 35%; October 21, 2018: 35%; October 21, 2019: 20%; October 21, 2020: 5%; October 21, 2021: 5%. The fair value was determined by using the closing share price of our common stock on the date the shares were issued.

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

The following discussion and analysis of the consolidated financial condition and results of operations should be read in conjunction with the Consolidated Financial Statements and Notes thereto, along with our 2013 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 September 30, 2014, we owned and operated a portfolio of 184 developed properties located in 27 states throughout the United States, including 151 MH communities, 24 RV communities, and 9 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 2013 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. 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 performance of an equity REIT. Under the National Association of Real Estate Investment Trusts (“NAREIT”) definition, FFO represents net income, excluding extraordinary items (as defined under GAAP), and gain (loss) on sales of depreciable 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 following our “Results of Operations".

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 United States 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 SITE

A key management tool used when evaluating performance and growth of our properties is a comparison of Same Site communities. Same Site communities consist of properties owned and operated throughout 2014 and 2013.  The Same Site data may change from time-to-time depending on acquisitions, dispositions, management discretion, significant transactions, or unique situations. The Same Site data in this Form 10-Q includes all properties acquired prior to December 31, 2012 and which we have owned and operated continuously since January 1, 2013.

In order to evaluate the growth of the Same Site communities, management has classified certain items differently than our GAAP statements. The reclassification difference between our GAAP statements and our Same Site 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 Site portfolio net of recovery.

The following tables reflect certain financial and other information for our Same Site communities as of and for the three months ended September 30, 2014 and 2013:

⁽²⁾    Occupied sites and occupancy % include MH and annual RV sites, and exclude transient RV sites, which are included in total developed sites.

⁽³⁾ Occupancy % excludes recently completed but vacant expansion sites.

⁽⁴⁾  Weighted average rent pertains to annual RV sites and excludes transient RV sites.

The 9.2% growth in NOI is primarily due to increased revenues of $4.3 million partially offset by additional expenses of $0.1 million.

Income from real property revenue consists of MH and RV site rent, and miscellaneous other property revenues.  The 6.5% growth in income from real property is primarily due to increased revenue from our MH and RV portfolio of $4.1 million due to the increased number of occupied home sites and the increase to our weighted average rental rate of 3.0%.  Additionally, other revenues increased by $0.2 million primarily due to increases in month to month fees and miscellaneous other charges and fee income.

31

SUN COMMUNITIES, INC.

Property operating expenses increased approximately $0.1 million, or 0.7%, compared to 2013. Of that increase, supplies and repair expenses increased $0.3 million primarily due to increased tree trimming and lawn services, and real estate taxes increased $0.3 million. Legal, taxes and insurance expenses also increased $0.1 million primarily due to increased property and casualty insurance expense and increased delinquency related legal fees. These increases were partially offset by a decrease in payroll and benefits expenses of $0.4 million primarily due to a decrease in health insurance expenses, an increase in capitalized leasing costs and a decrease in bad debt expense of $0.1 million.

HOME SALES AND RENTALS

We acquire pre-owned and repossessed manufactured homes generally located within our communities from lenders and dealers at substantial discounts.  We lease or sell these value priced homes to current and prospective residents.  We also purchase new homes to lease and sell to current and prospective residents.  

The following table reflects certain financial and other information for our Rental Program as of and for the three months ended September 30, 2014 and 2013 (in thousands, except for statistical information):

	Three Months Ended September 30,

Number of sold rental homes	208		239		(31		)	(13.0	)%
Weighted average monthly rental rate	$	816	$	795	$	21		2.6	%

⁽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 Rental Program and financial impact to our operations.

The 15.6% growth in NOI is primarily a result of the increased number of residents participating in the Rental Program and from increased monthly rental rates as indicated in the table above.

The increase in operating and maintenance expenses of $0.7 million was primarily a result of increased repair and refurbishment expenses of $0.3 million, of which approximately $0.1 million was due to increased refurbishment costs related to occupant turnover and $0.2 million was due to increased repair costs on occupied home rentals. In addition, insurance and property and use taxes increased $0.2 million and commissions increased $0.1 million. Each of these expense categories increased primarily due to the additional number of homes in the Rental Program.

Distributions from affiliates	$	400	$	700	$	(300	)	(42.9	)%

Ancillary revenues, net increased primarily due to increased vacation rental income of $2.0 million and increased merchandise income, primarily as a result of our newly acquired RV properties.

Real property general and administrative expenses increased primarily due to increased salaries, wages and bonus expenses of $0.4 million, increased deferred compensation expense of $0.2 million due to awards of restricted stock, increased legal expense of $0.1 million, increased travel expense of $0.1 million and increased tax expense of $0.1 million.

Transaction costs increased primarily due to due diligence costs related to the pending Green Courte acquisition announced in July 2014 (see Note 2).

Depreciation and amortization expenses increased as a result of additional depreciation and amortization of $1.4 million primarily related to our newly acquired properties, $1.2 million related to depreciation on investment property for use in our Rental Program, $0.7 million related to depreciation on homes in our vacation rental program and $0.3 million related to the amortization of in-place leases and promotions, partially offset by a reduction of approximately $2.6 million from the write off of the remaining net book value for assets replaced during the period.

Asset impairment charge of $0.8 million is a result of an impairment loss recorded on a long-lived asset for our MH and RV community in La Feria, Texas during three months ended September 30, 2014. We did not recognize any impairment losses in 2013.

Interest expense on debt, including interest on mandatorily redeemable debt, increased primarily as a result of a $0.3 million increase in expense associated with our secured borrowing arrangements, a $0.2 million increase in deferred financing cost amortization, a $0.1 million increase in mortgage interest and $0.1 million increase in interest expense on our lines of credit.

Gain on disposition of properties, net of $13.6 million is a result of the sale of six of our MH properties during the three months ended September 30, 2014 (see Note 2). We did not dispose of any properties in 2013.

Distributions from affiliate decreased $0.3 million. We suspended equity accounting 2010 on our affiliate, Origen, as our investment balance is zero. The income recorded is distribution income. The amount of the distribution is determined by Origen on a quarterly basis. See Note 7 to our financial statements.

Income from real property revenue consists of MH and RV site rent, and miscellaneous other property revenues.  The 6.6% growth in income from real property is primarily due to increased revenue from our MH and RV portfolio of $12.6 million as a result of the increased number of occupied home sites, the increase to our weighted average rental rate of 3.0% and an increase in transient RV revenue. Additionally, other revenues increased by $0.9 million primarily due to an increase in late fees and non-sufficient funds charge income, month to month fees, cable television royalties, application fees, and other charges and fee revenue.

Property operating expenses increased $1.9 million, or 3.0% compared to 2013. Of that increase, utilities expense increased $1.0 million due to increased gas and electric costs, primarily resulting from extreme temperatures experienced in certain areas of the country during the first part of 2014, and increased water and sewer costs. Supplies and repair expenses increased $0.6 million also primarily due to weather related maintenance and repair costs including snow removal, tree trimming and removal, community water systems repairs, vehicle maintenance and gasoline. Legal, taxes and insurance expenses increased $0.3 million primarily due to increased property and casualty insurance and increased delinquency related legal fees, and real estate taxes increased $0.2 million. Bad debt expense increased $0.1 million and miscellaneous expenses such as software maintenance, licenses and dues and bank service and credit card processing charges increased $0.2 million. These increases were partially offset by a decrease in payroll and benefits of $0.6 million primarily due to an increase in capitalized leasing costs and a decrease in health insurance costs.

⁽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 20.1% growth in NOI is primarily a result of the increased number of residents participating in the Rental Program and from increased monthly rental rates as indicated in the table above.

The increase in operating and maintenance expenses of $2.4 million was primarily a result of increased repair and refurbishment expenses of $1.5 million, of which approximately $0.8 million was due to increased refurbishment costs related to occupant turnover and $0.7 million was due to increased repair costs on occupied home rentals. In addition, insurance and personal property and use taxes increased $0.7 million due to the additional number of homes in the Rental Program, bad debt expense increased $0.4 million and commissions increased $0.1 million due to the increased number of new leases. These increases were partially offset by a decrease in marketing expense of $0.3 million.

Distributions from affiliates	$	1,200	$	1,550	$	(350	)	(22.6	)%

Ancillary revenues, net increased primarily due to increased vacation rental income of $2.9 million and increased merchandise income, primarily as a result of our newly acquired RV properties.

Interest income increased primarily due to an increase in interest income from collateralized receivables of $0.9 million, partially offset by a decrease in interest income from installment note receivables of $0.1 million.

Brokerage commissions and other revenues increased primarily due to a $0.2 million gain on the disposition of land and a $0.1 million increase in brokerage commissions.

Real property general and administrative expenses increased primarily due to increased salaries, wages and bonus expenses of $1.8 million, increased deferred compensation expense of $1.2 million due to awards of restricted stock, increased legal expense of $0.4 million and increased other expenses of $0.6 million primarily related to increased consulting fees, directors fees and software support and maintenance expenses.

Transactions costs increased primarily due to due diligence costs related to the pending Green Courte acquisition announced in July 2014 (see Note 2).

Depreciation and amortization expenses increased as a result of additional depreciation and amortization of $5.4 million primarily related to our newly acquired properties, $4.1 million related to depreciation on investment property for use in our Rental Program, $2.0 million related to depreciation on homes in our vacation rental program and $0.8 million related to the amortization of in-place leases and promotions, partially offset by a reduction of approximately $3.8 million from the write off of the remaining net book value for assets replaced during the period.

Asset impairment charge of $0.8 million is a result of an impairment loss recorded on a long-lived asset for our MH and RV community in La Feria, Texas during nine months ended September 30, 2014. We did not recognize any impairment losses in 2013.

Gain on disposition of properties, net of $14.5 million is a result of the sale of 10 MH properties during the nine months ended September 30, 2014 (see Note 2). We did not dispose of any properties in 2013.

Distributions from affiliate decreased $0.4 million. We suspended equity accounting in 2010 on our affiliate, Origen, as our investment balance is zero. The income recorded in 2013 is distribution income. The amount of the distribution is determined by Origen on a quarterly basis. See Note 7 to our financial statements.

FUNDS FROM OPERATIONS

We provide information regarding FFO as a supplemental measure of operating performance.  FFO is defined by NAREIT as net income (loss) (computed in accordance GAAP), excluding gains (or losses) from sales of depreciable operating property, plus real estate-related depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures. 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 unitholders 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 secured credit facility, and the use of debt and equity offerings under our automatic shelf registration statement.

During the nine months ended September 30, 2014, we acquired six RV communities with approximately 2,500 sites. We also disposed of 10 MH communities with approximately 3,300 sites. See Note 2 to our financial statements for details on the 2014 acquisitions and dispositions and Note 9 to our financial statements for related debt transactions.  

Additionally, during the nine months ended September 30, 2014, we entered into agreements to acquire a portfolio of manufactured home communities from the Green Courte Entities. The portfolio consists of 59 manufactured home communities comprising over 19,000 sites in eleven states, including nearly 11,000 sites located in Florida. Approximately 14,000 sites, or 71%, of the portfolio is included in age-restricted communities. In connection with this transaction, the Company will assume the Green Courte Entities' right to acquire an additional manufactured home community pursuant to a binding purchase agreement.

Total consideration for the acquisition is approximately $1.32 billion, including the assumption of approximately $560 million of debt. We will pay approximately $311 million in cash (increased by the reduction in assumed mortgage debt prior to closing), issue approximately $262 million of common stock and common OP units, and issue $175 million of newly-created Series A-4 Convertible Perpetual Preferred Stock or Convertible Perpetual Preferred Operating Limited Partnership units to the Green Courte Entities. Additionally, an affiliate of the Green Courte Entities has committed to make an investment of not less than approximately $13 million in the Company’s equity. See Note 2 to our financial statements for details on the closing of this acquisition. We intend to fund the cash portion of the consideration for this transaction through available cash and draws on our line of credit facilities.

We will continue to evaluate acquisition opportunities that meet our criteria for acquisition. Should additional investment opportunities arise in 2014, 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 nine months ended September 30, 2014, we invested $34.8 million in the acquisition of homes intended for the Rental Program net of proceeds from third party financing from home sales.  Expenditures for 2014 will be dependent 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 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 floor plan financing and working capital available on our secured lines of credit.

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

	Nine Months Ended September 30,
	2014			2013
Net Cash Provided by Operating Activities	$	109,259		$	94,326
Net Cash Used in Investing Activities	$	(248,622	)	$	(270,309	)
Net Cash Provided by Financing Activities	$	393,762		$	151,430

Operating Activities

Cash and cash equivalents increased by $254.4 million from $4.8 million as of December 31, 2013, to $259.2 million as of September 30, 2014. Net cash provided by operating activities increased by $14.9 million from $94.3 million for the nine months ended September 30, 2013 to $109.3 million for the nine months ended September 30, 2014.

45

SUN COMMUNITIES, INC.

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 2013 Annual Report.

Investing Activities

Net cash used in investing activities was $248.6 million for the nine months ended September 30, 2014, compared to $270.3 million for the nine months ended September 30, 2013. During 2014, proceeds related to the disposition of properties was $59.7 million. We did not dispose of any properties during 2013. Net cash used in investing activities during 2013 includes an investment in a note receivable, which was extinguished in a net cash settlement during the acquisition of the properties upon which the note receivable was attributable to. No such investment was made during the nine months ended September 30, 2014. These items are partially offset by a $50.0 million payment for deposit on the pending Green Courte acquisition (see Note 2) as well as increased cash used for acquisition of properties. Also contributing to the decrease in cash used for investing activities are decreased investment in properties, increased proceeds related to the disposition of assets and depreciable homes, net, and increased repayments of notes and other receivables.

Financing Activities

Net cash provided by financing activities was $393.8 million for the nine months ended September 30, 2014, compared to $151.4 million for the nine months ended September 30, 2013. The increase is primarily related to increased net proceeds received from the issuance of additional shares of common stock and increased proceeds from the issuance of other debt, partially offset by increased net payments on our lines of credit and increased distributions to our stockholders and OP unit holders.

Financial Flexibility

We have a senior secured revolving credit facility (the "Facility") with a maximum borrowing capacity of $350.0 million, subject to certain borrowing base calculations, and a built in accordion allowing for up to $250.0 million in additional borrowings. As of September 30, 2014, we did not have a balance outstanding under the Facility. As of December 31, 2013, we had approximately $178.1 million outstanding under the Facility. Borrowings under the Facility bear 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 Facility, which can range from 1.65% to 2.90%.  During 2014, the highest balance on the Facility was $247.3 million.  The borrowings under the Facility mature May 15, 2017, which date can be extended for one additional year at our option, subject to the satisfaction of certain conditions as defined in the credit agreement. Although the Facility is a committed facility, the financial failure of one or more of the participating financial institutions may reduce the amount of credit available to us.

Our 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 September 30, 2014, we had outstanding letters of credit to back standby letters of credit totaling approximately $3.2 million, leaving approximately $346.8 million available under our secured line 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 September 30, 2014
Maximum Leverage Ratio	<68.5%	35.6%
Minimum Fixed Charge Coverage Ratio	>1.40	2.42
Minimum Tangible Net Worth	>$990,159	$1,671,581
Maximum Dividend Payout Ratio	<95.0%	68.4%

Market and Economic Conditions

While the U.S. continues to see moderate signs of recovery including improvements in job growth, motor vehicle sales and the housing market, the improvements are somewhat inconsistent. The Federal Reserve’s tapering of monetary stimulus which began in December 2013, and which has long suppressed long term interest rates, brings the risk of rising interest rates to the forefront which could move investor sentiment away from the real estate sector. The change in monetary policy could also be perceived as the precursor to real economic improvement which could bode well for real estate operations. 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 September 30, 2014, we had 70 unencumbered properties with an estimated market value of $744.6 million. Fifty-six of these unencumbered properties support the borrowing base for our $350.0 million secured 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 2013 Annual Report.  If we are unable to obtain additional debt or equity financing on acceptable terms, our business, results of operations and financial condition would be adversely impacted.

As of September 30, 2014, our net debt plus preferred stock to enterprise value approximated 32.1% (assuming conversion of all common OP units, A-1 preferred OP units and A-3 preferred OP units to shares of common stock). Our debt has a weighted average maturity of approximately 7.4 years and a weighted average interest rate of 5.2%.

Capital expenditures for the nine months ended September 30, 2014 and 2013 included recurring capital expenditures of $7.8 million and $9.9 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 2014.

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 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 $162.4 million as of September 30, 2014. The first interest rate cap agreement has a cap rate of 11.27%, a notional amount of $152.4 million and a termination date of April 2015.  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 $161.5 million and $217.6 million as of September 30, 2014 and 2013, 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 $2.4 million and $1.7 million as of September 30, 2014 and 2013, respectively, based on the $316.4 million and $224.7 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 Securities and Exchange Act of 1934 (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 September 30, 2014 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In August 2014, the Financial Accounting Standards Board (the “FASB”) issued ASU No. 2014-15, (“ASU 2014-15”), “Disclosure of Uncertainties About an Entity’s Ability to Continue as a Going Concern”. ASU 2014-15 requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of the date the financial statements are issued and provides guidance on determining when and how to disclose going concern uncertainties in the financial statements. Certain disclosures will be required if conditions give rise to substantial doubt about an entity’s ability to continue as a going concern. ASU 2014-15 applies to all entities and is effective for annual and interim reporting periods ending after December 15, 2016, with early adoption permitted. We are currently evaluating the potential impacts the new standard will have on our quarterly reporting process.

In May 2014, the FASB issued ASU No. 2014-09, (“ASU 2014-09”), “Revenue from Contracts with Customers” as a new Topic, Accounting Standards Codification ("ASC") Topic 606. The objective of ASU 2014-19 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 the new standard, companies will perform a five-step analysis of transactions to determine when and how revenue is recognized. ASU 2014-09 applies to all contracts with customers except those that are within the scope of other topics in the FASB ASC. This ASU is effective for annual reporting periods (including interim periods within those periods) beginning after December 15, 2016 and shall be applied using either a full retrospective or

17.    Recent Accounting Pronouncements, continued

modified retrospective approach. Early adoption is not permitted. We are currently evaluating the new guidance and have not determined the impact this standard may have on our consolidated financial statements nor decided upon the method of adoption.

In April 2014, the FASB issued ASU No. 2014-08, "Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity" ("ASU 2014-08"). ASU 2014-08 raises the threshold for a disposal to qualify as a discontinued operation by requiring only those disposals of a component or group of components that represent a strategic shift or that will have a major effect on the Company’s operational and financial results and also requires new disclosures of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation. The guidance does not change the presentation requirements for discontinued operations in the statement where net income is presented. ASU 2014-08 also requires the reclassification of assets and liabilities of a discontinued operation in the statement of financial position for all prior periods presented. The standard expands the disclosures for discontinued operations and requires new disclosures related to individually material disposals that do not meet the definition of a discontinued operation, an entity's continuing involvement with a discontinued operation following the disposal date and retained equity method investments in a discontinued operation. ASU 2014-08 is effective for annual periods beginning on or after December 15, 2014 and interim periods within annual periods beginning on or after December 15, 2015. Early adoption is permitted but only for disposals (or classifications as held for sale) that have not been reported in financial statements previously issued or available for issue. We have chosen to early adopt this pronouncement and have applied the guidance to recent applicable disposals (see Note 2).

Impaired Long-Lived Assets Held and Used [Line Items]

Asset Impairment Charges [Text Block]

In September 2014, we recorded impairment charges of $0.8 million associated with a long-lived asset for an MH and RV community located in La Feria, Texas. This community consists of 280 developed sites. Circumstances that prompted this test of recoverability included a decrease in net operating income and the overall operating performance of the community. We recognized the impairment loss because the long-lived asset's carrying value was deemed not recoverable and exceeded the estimated fair value. We estimated the fair value of the long-lived asset based on discounted future cash flows and any potential disposition proceeds for the asset. The impairment loss is recorded in "Asset impairment charge" on our consolidated statements of operations.

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, establishes a fair value hierarchy that requires the use of observable market data, when available, and prioritizes the inputs to valuation techniques used to measure fair value in the following categories:

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 observable inputs and significant value drivers are observable in active markets.

Level 3—Model derived valuations in which one or more significant inputs or significant value drivers are unobservable, including assumptions developed by us.

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 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 observable inputs and significant value drivers are observable in active markets provided by brokers or dealers to determine the fair values of derivative instruments on a recurring basis (Level 2). See Note 15 for Derivative Instruments.

Installment Notes on Manufactured Homes

The net carrying value of the installment notes 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 5 for Installment Notes.

16.   Fair Value of Financial Instruments, continued

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 and rates currently prevailing for comparable loans and instruments of comparable maturities (Level 2). See Note 9 for Long-Term Debt and Lines of Credit.

Collateralized Receivables and Secured Borrowing

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 in 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 4 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 and presents the carrying values and fair values as of September 30, 2014 and December 31, 2013 that were measured using the valuation techniques described above. 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.

	September 30, 2014				December 31, 2013
Financial assets	Carrying Value		Fair Value		Carrying Value		Fair Value
Installment notes on manufactured homes, net	$	21,684	$	21,684	$	25,471	$	25,471

Collateralized Term Loans

In August 2014, we paid off $52.6 million of Fannie Mae ("FNMA") debt.

9.      Debt and Lines of Credit, continued

Additionally, in July and August 2014, we borrowed the aggregate amount of $63.5 million under five mortgage loans from Ladder Capital Finance, LLC ("Ladder"). The loans have a ten year term and a blended annual interest rate of 4.56%. The proceeds of the loans were used to pay down a portion of our senior secured line of credit.

In January 2014, we and four of our subsidiaries borrowed the aggregate amount of $99.0 million under four mortgage loans (each, an “Individual Loan” and, together, the “Loan”) from The Northwestern Mutual Life Insurance Company (“NM”) pursuant to a Master Loan Agreement with NM. Each Individual Loan accrues interest at a rate of 4.20% and matures on February 13, 2026. We and each of the four borrowers have guaranteed the Loan. The proceeds of the Loan were used to repay a portion of our senior secured line of credit.

The collateralized term loans totaling $1.1 billion as of September 30, 2014, are secured by 101 properties comprised of 39,997 sites representing approximately $746.0 million of net book value.

Aspen Preferred OP Units

The Aspen preferred OP units issued by the Operating Partnership are convertible into 526,212 shares of the Company's common stock based on a conversion price of $68 per share with a redemption date of January 1, 2024. The current preferred rate is 6.5%.

Secured Borrowing

See Note 4, "Transfers of Financial Assets", for additional information regarding our collateralized receivables and secured borrowing transactions.

Mortgage Notes

In September 2014, we paid in full the $13.5 million mortgage agreement secured by Cave Creek and Pine Trace. We also paid off the $2.4 million mortgage agreement secured by Brookside Village upon maturity.

In August 2014, we paid in full the entire $6.5 million mortgage agreement secured by Sheffield Estates upon maturity.

The mortgage notes totaling $118.0 million as of September 30, 2014, are collateralized by 14 properties comprised of 6,659 sites representing approximately $194.1 million of net book value.

Lines of Credit

We have a senior secured revolving credit facility with Citibank, N.A. and certain other lenders in the amount of $350.0 million (the "Facility"). The Facility has a four year term ending May 15, 2017, which can be extended for one additional year 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 $250.0 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 1.65% to 2.90%. Based on our calculation of the leverage ratio as of September 30, 2014, the margin was 1.65%. At September 30, 2014 we had no amount outstanding under the Facility and at December 31, 2013, we had approximately $178.1 million outstanding under the Facility. At September 30, 2014 and December 31, 2013, approximately $3.2 million and $2.7 million, respectively, of availability was used to back standby letters of credit.

The Facility is secured by a first priority lien on all of our equity interests in each entity that owns all or a portion of the properties constituting the borrowing base and collateral assignments of our senior and junior debt positions in certain borrowing base properties.

We also have a $20.0 million secured line of credit agreement collateralized by a portion of our rental home portfolio. The net book value of the rental homes pledged as security for the loan must meet or exceed 200% of the outstanding loan balance. The

9.      Debt and Lines of Credit, continued

terms of the agreement require interest only payments for the first five years, with the remainder of the term being amortized based on a 10 year term. The interest rate is the prime rate as published in the Wall Street Journal adjusted the first day of each calendar month plus 200 basis points with a minimum rate of 5.5%. At both September 30, 2014 and December 31, 2013, the effective interest rate was 5.5%, and there was no amount outstanding.

We have a $12.0 million manufactured home floor plan facility renewable indefinitely until our lender provides us 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 September 30, 2014, the effective interest rate was 7.0%.  The outstanding balance was zero and $3.3 million at September 30, 2014 and December 31, 2013, respectively.

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 September 30, 2014, we were in compliance with all covenants.

Equity Transactions

Equity Transactions

In September 2014, we closed an underwritten registered public offering of 6,900,000 shares of common stock at a price of $50.60 per share, which includes 900,000 shares sold to the underwriter pursuant to the full exercise of its option to purchase additional shares. Net proceeds from the offering were approximately $348.9 million after deducting expenses related to the offering. We intend to use the majority of the net proceeds of the offering to fund the cash portion of the purchase price for the previously-announced acquisition of MH communities from the Green Courte Entities (see Note 2) and use the remainder of the net proceeds from the offering to repay borrowings outstanding under the Facility. The consummation of the acquisition is subject to certain confirmatory diligence and customary closing conditions, including obtaining third party consents. If for any reason the acquisition is not consummated, we intend to use the net proceeds from the offering to repay borrowings outstanding under the Facility, fund possible future acquisitions of properties and for working capital and general corporate purposes.

In March 2014, we closed an underwritten registered public offering of 4,200,000 shares of common stock at a price of $44.45 per share, and in April 2014, the underwriters exercised their option to purchase an additional 630,000 shares of common stock at a price of $44.45 less the declared dividend of $0.65 per share. Net proceeds from the offering were $214.0 million after deducting underwriting discounts and the expenses related to the offering. We used the net proceeds of the offering to repay borrowings outstanding under the Facility, for acquisitions of properties and for working capital and general corporate purposes.

In November 2004, our Board of Directors authorized us to repurchase up to 1,000,000 shares of our common stock.  We have 400,000 common shares remaining in the repurchase program.  No common shares were repurchased during the nine months ended September 30, 2014 or 2013.  There is no expiration date specified for the buyback program.

Common OP unit holders can convert their common OP units into an equivalent number of shares of common stock at any time.  During the nine months ended September 30, 2014 and 2013, there were no common OP units converted to shares of common stock.

Subject to certain limitations, Series A-1 preferred OP unit holders may convert their Series A-1 preferred OP units to shares of our common stock at any time. During the nine months ended September 30, 2014, holders of Series A-1 preferred OP units converted 18,773 units to 45,785 shares of common stock. No such units were converted during the nine months ended September 30, 2013.

Cash distributions of $0.65 per share were declared for the quarter ended September 30, 2014. On October 17, 2014, cash payments of approximately $32.6 million for aggregate distributions were made to common stockholders, common OP unitholders and restricted stockholders of record as of September 30, 2014. In addition, cash distributions of $0.4453 per share were declared on the Company's Series A cumulative redeemable preferred stock. On October 15, 2014, cash payments of approximately $1.5 million for aggregate distributions were made to Series A cumulative redeemable preferred stockholders of record as of October 1, 2014.

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. 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 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 according to

4.      Transfers of Financial Assets, continued

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.  The percentage used to determine the repurchase price of the outstanding principal balance on the installment note is based on the number of payments made on the note. In general, the repurchase price is determined as follows:

Number of Payments	Repurchase %
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 in Notes and Other Receivables (see Note 5), and the cash proceeds received from these transactions have been classified as a secured borrowing in Debt (see Note 9) within the consolidated balance sheets. The balance of the collateralized receivables was $117.5 million (net of allowance of $0.8 million) and $109.8 million (net of allowance of $0.7 million) as of September 30, 2014 and December 31, 2013, respectively.  The outstanding balance on the secured borrowing was $118.2 million and $110.5 million as of September 30, 2014 and December 31, 2013, 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):

	Nine Months Ended
	September 30, 2014
Beginning balance	$	110,510
Financed sales of manufactured homes	24,840
Principal payments and payoffs from our customers	(9,723		)
Principal reduction from repurchased homes	(7,397		)
Total activity	7,720
Ending balance	$	118,230

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 $3.0 million and $2.7 million and $8.6 million and $7.7 million for the three and nine months endedSeptember 30, 2014 and 2013, respectively.

Land improvements and buildings consist primarily of infrastructure, roads, landscaping, clubhouses, maintenance buildings and amenities.

In September 2014, we recorded impairment charges of $0.8 million associated with a long-lived asset for an MH and RV community located in La Feria, Texas. This community consists of 280 developed sites. Circumstances that prompted this test of recoverability included a decrease in net operating income and the overall operating performance of the community. We recognized the impairment loss because the long-lived asset's carrying value was deemed not recoverable and exceeded the estimated fair value. We estimated the fair value of the long-lived asset based on discounted future cash flows and any potential disposition proceeds for the asset. The impairment loss is recorded in "Asset impairment charge" on our consolidated statements of operations.

Derivative Instruments And Hedging Activities

Derivative Instruments and Hedging Activities Disclosure [Abstract]

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 swaps and caps are used to accomplish this objective. We require hedging derivative instruments to be highly effective in reducing the risk exposure that they are designated to hedge. We formally designate any instrument that meets these hedging criteria as a hedge at the inception of the derivative contract. We do not enter into derivative instruments for speculative purposes.

The following table provides the terms of our interestrate derivative contracts that were in effect as of September 30, 2014:

Type	Purpose	Effective Date	Maturity Date	Notional  (in millions)		Based on	Variable Rate	Fixed Rate	Spread	Effective Fixed Rate
Cap	Cap Floating Rate	4/1/2012	4/1/2015	$	152.4	3 Month LIBOR	0.2310%	11.2650%	—%	N/A
Cap	Cap Floating Rate	10/3/2011	10/3/2016	$	10.0	3 Month LIBOR	0.2310%	11.0200%	—%	N/A

In January 2014, our interest rate swap agreement with a notional amount of $20.0 million expired. We did not enter into a new interest rate swap agreement.

In accordance with ASC Topic 815, Derivatives and Hedging, we have recorded the fair value of our derivative instruments designated as cash flow hedges on the balance sheet. See Note 16 for information on the determination of fair value for the derivative instruments.  The following table summarizes the fair value of derivative instruments included in our consolidated balance sheets as of September 30, 2014 and December 31, 2013 (in thousands):

	Asset Derivatives					Liability Derivatives
	Balance Sheet Location	Fair Value				Balance Sheet Location	Fair Value
Derivatives designated as hedging instruments		September 30, 2014		December 31, 2013			September 30, 2014		December 31, 2013
Interest rate swaps and cap agreement	Other assets	$	—	$	—	Other liabilities	$	—	$	97
Total derivatives designated as hedging instruments		$	—	$	—		$	—	$	97

These valuation adjustments will only be realized under certain situations. For example, if we terminate contracts prior to maturity or if derivatives fail to qualify for hedge accounting, we would need to amortize amounts currently included in accumulated other comprehensive income into interest expense over the terms of the derivative contracts.  We did not terminate our swap prior to maturity, and it did not fail to qualify for hedge accounting; therefore, the net of valuation adjustments through the maturity date approximated zero.

Our hedges were highly effective and had minimal effect on income.  The following tables summarize the impact of derivative instruments for the three and nine months ended September 30, 2014 and 2013 as recorded in the consolidated statements of operations (in thousands):

Derivatives in Cash Flow Hedging	Amount of Gain or (Loss) Recognized in OCI (Effective Portion)				Location of Gain or (Loss) Reclassified from Accumulated OCI into Income (Effective Portion)	Amount of Gain or (Loss) Reclassified from Accumulated OCI into Income (Effective Portion)

Our financial derivative instruments are designated and qualify as cash flow hedges and the effective portion of the gain or loss on such hedges are reported as a component of accumulated other comprehensive income in our consolidated balance sheets.

To the extent that the hedging relationship is not effective or does not qualify as a cash flow hedge, the ineffective portion is recorded in interest expense. Hedges that received designated hedge accounting treatment are evaluated for effectiveness at the time that they are designated as well as through the hedging period. No gain or loss was recognized in the consolidated financial

statements related to hedge ineffectiveness or to amounts excluded from effectiveness testing on our cash flow hedge during the three and nine months ended September 30, 2014 and 2013.

Certain of our derivative instruments contain provisions that require us to provide ongoing collateralization on derivative instruments in a liability position.  As of December 31, 2013, we had collateral deposits recorded in other assets of approximately $0.7 million. As of September 30, 2014, we had no such deposits recorded.

Share-Based Compensation

In July 2014, the Company and Gary A. Shiffman (the Company's Chairman and Chief Executive Officer) entered into an Amended and Restated Restricted Stock Award Agreement, which amended and restated in its entirety the Restricted Stock Award Agreement dated June 20, 2013 between the Company and Mr. Shiffman. Under the original stock award agreement, the Company granted Mr. Shiffman 250,000 restricted shares of the Company's common stock, of which 175,000 restricted shares were awarded in respect of the performance of Mr. Shiffman and the Company over the prior three years and 75,000 restricted shares were awarded to induce Mr. Shiffman to execute a new five-year employment agreement. All of these restricted shares were scheduled to vest over time through June 2020. The restated stock award agreement amended the vesting schedule of the restricted shares, of which 100,000 restricted shares are now subject to performance vesting and the remaining 150,000 shares will vest over time through June 2020.

In July 2014, we granted 3,500 shares of restricted stock to an employee under our Sun Communities Inc. Equity Incentive Plan ("2009 Equity Plan"). The restricted shares had a fair value of $50.09 per share and will vest as follows: July 2, 2017: 35%; July 2, 2018: 35%; July 2, 2019: 20%; July 2, 2020: 5%; July 2, 2021: 5%. The fair value was determined by using the closing share price of our common stock on the date the shares were issued.

In June 2014, we granted 20,250 shares of restricted stock to employees under our 2009 Equity Plan. The restricted shares had a fair value of $49.84 per share and will vest as follows: June 30, 2017: 35%; June 30, 2018: 35%; June 30, 2019: 20%; June 30, 2020: 5%; June 30, 2021: 5%. The fair value was determined by using the closing share price of our common stock on the date the shares were issued.

In June 2014, we also granted 50,000 shares of restricted stock to our executive officers under our 2009 Equity Plan. The restricted shares had a fair value of $49.84 per share and will vest as follows: June 30, 2018: 20%; June 30, 2019: 30%; June 30, 2020: 35%; June 30, 2021: 10%; June 30, 2022: 5%. The fair value was determined by using the closing share price of our common stock on the date the shares were issued.

In February 2014, we granted 16,000 shares of restricted stock to an executive officer and a key employee under our 2009 Equity Plan. The restricted shares had a fair value of $48.01 per share and will vest as follows: February 12, 2018: 20%; February 12, 2019: 30%; February 12, 2020: 35%; February 12, 2021: 10%; February 12, 2022: 5%. The fair value was determined by using the closing share price of our common stock on the date the shares were issued.

In February 2014, we granted 14,000 shares of restricted stock to our directors under our First Amended and Restated 2004 Non-Employee Director Option Plan. The awards vest on February 12, 2017, and had a fair value of $48.01 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 nine months ended September 30, 2014, 4,904 shares of common stock were issued in connection with the exercise of stock options and the net proceeds received were $0.1 million.

The vesting requirements for 54,863 restricted shares granted to our executives and employees were satisfied during the nine months ended September 30, 2014.

At September 30, 2014 and 2013, 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 own 5,000,000 shares of common stock of Origen which approximates an ownership interest of 19%. Although it is no longer originating or servicing loans, Origen continues to manage an existing portfolio of manufactured home loans and asset backed securities. We have suspended equity accounting for this investment as the carrying value of our investment is zero. We do, however, receive income from distributions on our shares of Origen common stock.  Our investment in Origen had a market value of approximately $8.4 million based on a quoted market closing price of $1.68 per share from the OTC Pink Marketplace as of September 30, 2014.

In September 2014, Origen announced that it has entered into an agreement to sell substantially all of its assets to an affiliate of GoldenTree Asset Management LP. Contingent upon the closing of the sale, Origen plans to dissolve and liquidate. The sale is pending stockholder approval.

Variable interest entities ("VIEs") that are consolidated include Rudgate Village SPE, LLC, Rudgate Clinton SPE, LLC and Rudgate Clinton Estates SPE, LLC (the “Rudgate Borrowers”). We concluded that the Rudgate Borrowers qualify as VIEs as we are the primary beneficiary and hold a controlling financial interest 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.

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

We have elected to be taxed as a real estate investment trust (“REIT”) as defined under Section 856(c) of the Internal Revenue Code of 1986 (“Code”), as amended. In order for us to qualify as a REIT, at least ninety-five percent (95%) of our gross income in any year must be derived from qualifying sources. In addition, a REIT must distribute at least ninety percent (90%) of its REIT ordinary taxable income to its stockholders.

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 September 30, 2014.

As a REIT, we generally will not be subject to 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 and to U.S. federal income and excise taxes on our undistributed income.

SHS, our taxable REIT subsidiary, is subject to U.S. federal 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. A federal deferred tax asset of $1.0 million is included in other assets in our consolidated balance sheets as of September 30, 2014 and December 31, 2013.

We had no unrecognized tax benefits as of September 30, 2014 and 2013. We expect no significant increases or decreases in unrecognized tax benefits due to changes in tax positions within one year of September 30, 2014.

We classify certain state taxes as income taxes for financial reporting purposes. We record Texas Margin Tax as income tax in our financial statements, and we recorded a provision for state income taxes of approximately $0.1 million for the three months ended September 30, 2014 and 2013, and $0.2 million for the nine months ended September 30, 2014 and 2013.

Commitments And Contingencies

Commitments and Contingencies

On June 4, 2010, we settled all of the claims arising out of the litigation filed in 2004 by TJ Holdings, LLC in the Superior Court of Guilford County, North Carolina and the associated arbitration proceeding commenced by TJ Holdings in Southfield, Michigan. Under the terms of the settlement agreement, in which neither party admitted any liability whatsoever, we paid TJ Holdings $360,000. In addition, pursuant to this settlement, TJ Holdings’ percentage ownership interest in Sun/Forest, LLC will be increased on a one time basis, in the event of a sale or refinance of all of the SunChamp Properties, to between 9.03% and 28.99% depending on our average closing stock price as reported by the NYSE during the 30 days preceding the sale or refinance of all the SunChamp Properties. Once this percentage ownership interest has been adjusted, there will be no further adjustments from subsequent sales or refinances of the SunChamp Properties. The likelihood of a sale or refinancing of all of the SunChamp properties is not probable as these properties continue to see growth potential nor do we have a need to refinance all of the properties, so we do not expect it to have a material adverse impact on our results of operations or financial condition.

We are involved in various other 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.

Real Estate Acquisitions

Real Estate Acquisitions and Dispositions

Green Courte Real Estate Partners, LLC

In July 2014, we entered into agreements to acquire a portfolio of manufactured home communities from Green Courte Real Estate Partners, LLC sponsored funds (the "Green Courte Entities"). The portfolio consists of 59 manufactured home communities comprising over 19,000 sites in eleven states, including nearly 11,000 sites located in Florida. Approximately 14,000 sites, or 71%, of the portfolio is included in age-restricted communities. In connection with this transaction, the Company will assume the Green Courte Entities' right to acquire an additional manufactured home community pursuant to a binding purchase agreement.

Total consideration for the acquisition is approximately $1.32 billion, including the assumption of approximately $560 million of debt. We will pay approximately $311 million in cash (increased by the reduction in assumed mortgage debt prior to closing), issue approximately $262 million of common stock and common OP units, and issue $175 million of newly-created Series A-4 Convertible Perpetual Preferred Stock or Convertible Perpetual Preferred Operating Limited Partnership units to the Green Courte Entities. Additionally, an affiliate of the Green Courte Entities has committed to make an investment of not less than approximately $13 million in the Company’s equity.

Subject to certain conditions, we anticipate that the acquisition will occur in two separate closings. The closing with respect to 34 communities is anticipated to occur 10 business days after the loan assumption approval is obtained for a sufficient number of communities as set forth in the acquisition agreements, but not later than December 31, 2014 (or such earlier date as we determine upon notice to the Green Courte Entities). The closing with respect to the remaining 25 communities is anticipated to occur on January 6, 2015. The consummation of the acquisition is subject to certain confirmatory diligence and customary closing conditions, including obtaining certain third party consents. As a result, there can be no assurances as to the actual closings or the timing of either of the closings.

Pursuant to the acquisition agreements, we made an earnest money deposit in the aggregate amount of $50 million (“Earnest Money Deposit”). The Earnest Money Deposit may be forfeited if we fail to close on the transactions contemplated by any definitive agreement in breach of the terms thereof and such breach continues for a period of 10 days without cure. The Earnest Money Deposit is the sole remedy for any such breach and shall serve as liquidated damages, except that if such a default occurs after the first closing, we shall also pay the Green Courte Entities the sum of $25 million as additional liquidated damages.

Acquisitions

In June 2014, we acquired Lake Rudolph Campground and Recreational Vehicle Resort ("Lake Rudolph"), a recreational vehicle ("RV") community with 503 sites located in Santa Claus, Indiana.

In April 2014, we acquired Saco/Old Orchard Beach RV Resort ("Saco"), a community with 127 sites located in Saco, Maine.

In February 2014, we acquired Driftwood Camping Resort ("Driftwood"), an RV community with 698 sites and expansion potential of approximately 30 sites located in Clermont, New Jersey, and Seashore Campsites RV and Campground ("Seashore"), an RV community with 685 sites located in Cape May, New Jersey.

In January 2014, we acquired Castaways RV Resort & Campground ("Castaways"), an RV community with 369 sites and expansion potential of approximately 25 sites located in Worcester County, Maryland, and Wine Country RV Resort ("Wine Country"), an RV community with 166 sites and expansion potential of approximately 34 sites located in Paso Robles, California.

The purchase price allocations for Wine Country, Castaways, Seashore, Driftwood, Saco and Lake Rudolph are preliminary and may be adjusted as final costs and final valuations are determined.

The amount of revenue and net income included in the consolidated statements of operations for the three and nine months ended September 30, 2014 for all acquisitions described above is set forth in the following table (in thousands):

The following unaudited pro forma financial information presents the results of our operations for the three and nine months ended September 30, 2014 and 2013 as if the properties were acquired on January 1, 2013. The unaudited pro forma results reflect certain adjustments for items that are not expected to have a continuing impact, such as adjustments for transaction costs incurred, management fees and purchase accounting. The information presented below has been prepared for comparative purposes only and does not purport to be indicative of either future results of operations or the results of operations that would have actually occurred had the acquisitions been consummated on January 1, 2013 (in thousands, except per-share data).

Transaction costs of approximately $2.4 million and $0.6 million and $4.3 million and $2.8 million have been incurred for the three and nine months ended September 30, 2014 and 2013, respectively, and are presented as “Transaction costs” in our consolidated statements of operations.

2.      Real Estate Acquisitions and Dispositions, continued

Dispositions

During the nine months ended September 30, 2014, we closed on the sales of 10 manufactured housing ("MH") communities: Bedford Hills, White Oak, Falcon Pointe, Timberbrook, Woodlake Estates, Byrne Hill, Continental Estates, Davison East, Countryside Village and Desert View Village. During the first quarter of 2014, the Company chose to early adopt Accounting Standards Update ("ASU") 2014-08, "Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity" ("ASU 2014-08"). Pursuant to ASU 2014-08, the disposals of the communities do not qualify for presentation as discontinued operations, as the sales do not have a major impact on our operations and financial results and do not represent a strategic shift. Additionally, the communities are not considered individually significant components and therefore do not qualify for presentation as discontinued operations. A gain of $14.5 million is recorded in "Gain on disposition of properties, net" in our consolidated statement of operations.

Subsequent Events

We have evaluated our financial statements for subsequent events through the date that this Form 10-Q was issued.

Settlement Agreement

In October 2014, we entered into a settlement agreement with Robert C. Morgan, Robert Moser and the selling entities of each of the 10 RV communities that we acquired in February 2013. The settlement was related to various warranties, representations and indemnities included in the agreements under which we acquired the RV communities, including a covenant made by the sellers related to the 2012 revenue of the acquired properties. A gain of approximately $4.5 million will be recorded in the fourth quarter of 2014.

Share-based Compensation

In October 2014, we granted 8,000 shares of restricted stock to employees under our 2009 Equity Plan. The restricted shares had a fair value of $54.26 per share and will vest as follows: October 21, 2017: 35%; October 21, 2018: 35%; October 21, 2019: 20%; October 21, 2020: 5%; October 21, 2021: 5%. The fair value was determined by using the closing share price of our common stock on the date the shares were issued.

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 the Company's 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 Real Property Operations’ revenues and is expected to approximate $31.7 million annually. This transient revenue was recognized 25.2%, 18.2% and 43.2% in the first, second and third quarters, respectively, and is expected to be recognized 13.4% in the fourth quarter of 2014. In 2013, transient revenue was $17.4 million and was recognized 40.0% in the first quarter, 15.0% in the second quarter, 30.0% in the third quarter and 15.0% in the fourth quarter.
