Dispositions

During January 2015, we completed the sale of Valley Brook, a MH community located in Indiana. Pursuant to Accounting Standards Update ("ASU") 2014-08, "Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity" ("ASU 2014-08"), the disposal of the community does not qualify for presentation as a discontinued operation, as the sale does not have a major impact on our operations and financial results and does not represent a strategic shift. Additionally, the community is not considered an individually significant component and therefore does not qualify for presentation as a discontinued operation. A gain of $8.8 million is recorded in "Gain on disposition of properties, net" in our consolidated statements of operations.

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 $133.1 million (net of allowance of $0.6 million) and $123.0 million (net of allowance of $0.7 million) as of June 30, 2015 and December 31, 2014, respectively.  The outstanding balance on the secured borrowing was $133.7 million and $123.7 million as of June 30, 2015 and December 31, 2014, respectively.

The balances of the collateralized receivables and secured borrowings fluctuate. The balances increase as additional notes receivable are transferred and exchanged for cash proceeds. The balances are reduced as the related collateralized receivables are collected from the customers, or as the underlying collateral is repurchased. The change in the aggregate gross principal balance of the collateralized receivables is as follows (in thousands):

	Six Months Ended
	June 30, 2015
Beginning balance	$	123,650
Financed sales of manufactured homes	18,175
Principal payments and payoffs from our customers	(3,857		)
Principal reduction from repurchased homes	(4,222		)
Total activity	10,096
Ending balance	$	133,746

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 $3.3 million and $2.9 million and $6.3 million and $5.6 million for the three and six months endedJune 30, 2015 and 2014, respectively.

7.      Investment in Affiliates

Origen Financial Services, LLC (“OFS LLC”)

At June 30, 2015 and December 31, 2014, 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%. We had suspended equity accounting for this investment as the carrying value of our investment was zero. In January 2015, Origen completed the sale of substantially all of its assets to an affiliate of GoldenTree Asset Management LP and has announced its intention to dissolve and liquidate. During the second quarter of 2015, and as disclosed in a press release on March 30, 2015, Origen made an initial distribution of $1.50 per share to its stockholders of record as of April 13, 2015, retaining approximately $6.2 million for expected dissolution and wind down costs and expenses and contingencies. Depending on the actual cost of estimated wind down expenses, Origen may make one or more additional interim distributions of excess cash to stockholders prior to completing liquidation. Upon completion of liquidation, Origen will distribute remaining cash, if any, to stockholders. During the three months ended June 30, 2015, we received an initial distribution of $7.5 million from Origen.

8.      Consolidated Variable Interest Entities

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

The following table summarizes the assets and liabilities included in our consolidated balance sheets after appropriate eliminations (in thousands):

	June 30, 2015			December 31, 2014

Investment property, net and other assets related to the consolidated VIEs comprised approximately 2.4% and 3.4% of our consolidated total assets and debt and other liabilities comprised approximately 3.0% and 3.8% of our consolidated total liabilities at June 30, 2015 and December 31, 2014, respectively. Noncontrolling interest related to the consolidated VIEs comprised less than 1.0% of our consolidated total equity at June 30, 2015 and December 31, 2014.

Collateralized Term Loans

In January 2015, in relation to the acquisition of the Green Courte properties (see Note 2), we refinanced approximately $90.8 million of mortgage debt on 10 of the communities (resulting in proceeds of $112.3 million) at a weighted average interest rate of 3.87% per annum and a weighted average term of 14.1 years. We also assumed approximately $201.4 million of mortgage debt at a weighted average interest rate of 5.74% and a weighted average remaining term of 6.3 years.

In March 2015, in relation to the acquisition of Meadowlands (see Note 2), we assumed a $6.3 million mortgage with an interest rate of 6.5% and a remaining term of 6.5 years. Also, in relation to this acquisition, we entered into a note with the seller for $2.4 million that bears no interest but is payable in three equal yearly installments beginning in March 2016.

In April 2015, in relation to the acquisition of the Berger properties (see Note 2), we assumed debt with a fair market value of $169.9 million on the communities with a weighted average interest rate of 5.17% and a weighted average remaining term of 6.3 years.

In May 2015, we defeased a total of $70.6 million aggregate principal amount of collateralized term loans with an interest rate of 5.32% that were due to mature on July 1, 2016, releasing 10 communities. As a result of the transaction we recognized a loss on debt extinguishment of $2.8 million that is reflected in our consolidated statement of operations.

The collateralized term loans totaling $2.2 billion as of June 30, 2015, are secured by 168 properties comprised of 59,451 sites representing approximately $2.6 billion of net book value.

Preferred OP Units

Included in Preferred OP units is $34.7 million of Aspen preferred OP units issued by the Operating Partnership which are convertible into 509,676 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 distribution rate is 6.5%.

Secured Borrowing

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

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 June 30, 2015, the margin was 1.70%. We had $33.1 million outstanding as of June 30, 2015, with an effective interest rate of 2.71%, and no amount outstanding as of December 31, 2014 under the Facility. At June 30, 2015 and December 31, 2014, approximately $3.2 million 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 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 June 30, 2015, the effective interest rate was 7.0%.  The outstanding balance was $4.6 million and $5.8 million at June 30, 2015 and December 31, 2014, 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 June 30, 2015, we were in compliance with all covenants.

10.      Equity and Mezzanine Securities

In June 2015, we issued to GCP Fund III Ancillary Holding, LLC (i) 25,664 shares of common stock at an issuance price of $50.00 per share or $1,283,200 in the aggregate, and (ii) 34,219 shares of 6.50% Series A-4 Cumulative Convertible Preferred Stock at an issuance price of $25.00 per share, or $855,475 in the aggregate.

11.      Share-Based Compensation

In May 2015, we granted 25,000 shares of restricted stock to an executive officer under our Sun Communities, Inc. Equity Incentive Plan ("2009 Equity Plan"). The shares had a fair value of $62.94 per share and will vest as follows: May 19, 2018: 35%; May 19, 2019: 35%; May 19, 2020: 20%; May 19, 2021: 5%; and May 19, 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 April 2015, we granted 145,000 shares of restricted stock to our executive officers under our 2009 Equity Plan. The shares had a fair value of $63.81 per share. Half of the shares are subject to time vesting as follows: April 14, 2018: 20%; April 14, 2019: 30%; April 14, 2020: 35%; April 14, 2021: 10%; and April 14, 2022: 5%. The remaining 72,500 shares are subject to market and performance conditions which vest over time through April 2020. Share-based compensation for restricted stock awards with performance conditions is measured based on an estimate of shares expected to vest. We estimate the fair value of share-based compensation for restricted stock with market conditions using a Monte Carlo simulation.

In February 2015, we granted 19,800 shares of restricted stock to our non-employee directors under our First Amended and Restated 2004 Non-Employee Director Option Plan. The awards vest on February 11, 2018, and had a fair value of $65.87 per share. The fair value was determined by using the closing share price of our common stock on the date the shares were issued.

In January 2015, we granted 1,000 shares of restricted stock to key employees under our 2009 Equity Plan. The restricted shares had a fair value of $65.48 per share and will vest as follows: January 8, 2018: 35%; January 8, 2019: 35%; January 8, 2020: 20%;

January 8, 2021: 5%; and January 8, 2022: 5%. The fair value was determined by using the closing share price of our common stock on the date the shares were issued.

During the six months ended June 30, 2015 and 2014, 4,084 and 4,904 shares of common stock, respectively, were issued in connection with the exercise of stock options, and the net proceeds received during both periods 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 $35.8 million annually. This transient revenue was recognized 24.5% and 19.2% in the first and second quarters, respectively, and is expected to be recognized 42.6% in the third quarter and 13.7% in the fourth quarter of 2015. In 2014, transient revenue was $31.6 million and was recognized 25.3% in the first quarter, 18.3% in the second quarter, 43.3% in the third quarter and 13.1% in the fourth quarter.

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

13.    Income Taxes

We have elected to be taxed as a real estate investment trust (“REIT”) pursuant to Section 856(c) of the Internal Revenue Code of 1986 (“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 (i.e., some on an annual and quarterly basis) established under highly technical and complex Code provisions for which there are only limited judicial or administrative interpretations, and involves the determination of various factual matters and circumstances not entirely within our control. In addition, frequent changes occur in the area of REIT taxation which requires us to continually monitor our tax status. We analyzed the various REIT tests and confirmed that we continued to qualify as a REIT for the quarter ended June 30, 2015.

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 June 30, 2015 and December 31, 2014.

We had no unrecognized tax benefits as of June 30, 2015 and 2014. We expect no significant increases or decreases in unrecognized tax benefits due to changes in tax positions within one year of June 30, 2015.

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 June 30, 2015 and the three and six months ended June 30, 2014, and $0.2 million for the six months ended June 30, 2015.

SHS is currently under examination by the Internal Revenue Service ("IRS") for tax year 2013. To date, we have not received any formal notices of proposed adjustments from the IRS related to this or any other examination periods.

14.    Earnings Per Share

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

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 caps are used to accomplish this objective. We do not enter into derivative instruments for speculative purposes nor do we have any swaps in a hedging arrangement.

The following table provides the terms of our interestrate derivative contracts that were in effect as of June 30, 2015:

Type	Purpose	Effective Date	Maturity Date	Notional  (in millions)		Based on	Variable Rate	Fixed Rate	Spread	Effective Fixed Rate
Cap	Cap Floating Rate	4/1/2015	4/1/2018	$	150.1	3 Month LIBOR	0.2708%	9.0000%	—%	N/A
Cap	Cap Floating Rate	10/3/2011	10/3/2016	$	10.0	3 Month LIBOR	0.2708%	11.0200%	—%	N/A

In accordance with ASC Topic 815, Derivatives and Hedging, derivative instruments are recorded at fair value within Other assets or Other liabilities on the balance sheet. As of June 30, 2015 and December 31, 2014, the fair value of the derivatives was zero.

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.

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.

16.   Fair Value of Financial Instruments, continued

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 require disclosure of their fair values on a recurring basis and presents the carrying values and fair values as of June 30, 2015 and December 31, 2014 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.

	June 30, 2015				December 31, 2014
Financial assets	Carrying Value		Fair Value		Carrying Value		Fair Value
Installment notes on manufactured homes, net	$	24,023	$	24,023	$	25,884	$	25,884

Lines of credit	$	37,742	$	37,742	$	5,794	$	5,794

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 April 2015, the FASB issued ASU No. 2015-03, "Simplifying the Presentation of Debt Issuance Costs," ("ASU 2015-03"). ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The standard is effective for annual reporting periods beginning after December 15, 2015, and interim periods within those years, with early adoption permitted. We are currently evaluating the potential impact the new standard will have on our consolidated financial statements.

In February 2015, the FASB issued ASU No. 2015-02, "Amendments to the Consolidation Analysis," ("ASU 2015-02"). ASU 2015-02 eliminates the deferral of FAS 167, which has allowed entities with interests in certain investment funds to follow the previous consolidation guidance in FIN 46(R), and makes other changes to both the variable interest model and the voting model. While the guidance is aimed at asset managers, it will affect all reporting entities that have variable interests in other legal entities (e.g., limited partnerships, similar entities and certain corporations). In some cases, consolidation conclusions will change. In other cases, reporting entities will need to provide additional disclosures about entities that currently aren’t considered VIEs but will be considered VIEs under the new guidance provided they have a variable interest in those VIEs. The standard is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015, with early adoption permitted. We are currently evaluating the potential impact the new standard will have on our consolidated financial statements.

18.   Commitments and Contingencies

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

19.   Subsequent Event

On July 29, 2015, the Company entered into a repurchase agreement with certain holders of the Company’s 6.50% Series A-4 Cumulative Convertible Preferred Stock under which, at the holders’ election, the Company is obligated to repurchase up to 5,926,322 shares of the Series A-4 preferred stock from the holders of those shares. There are 6,364,770 Series A-4 preferred shares currently issued and outstanding, and 438,448 Series A-4 preferred shares are not subject to the repurchase agreement. Each holder of Series A-4 preferred shares subject to the repurchase agreement may elect to sell its Series A-4 preferred shares to the Company until August 10, 2015. The purchase price is $31.08 per Series A-4 preferred share, which consists of a price per share of $30.90 plus $0.18 for accrued and unpaid distributions from and including June 30, 2015 to, but not including, August 10, 2015. Each Series A-4 Preferred Share has a liquidation preference of $25.00 per share, and is convertible into approximately 0.4444 shares of the Company’s common stock.

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 2014 Annual Report. Capitalized terms are used as defined elsewhere in this Form 10-Q.

OVERVIEW

We are a fully integrated, self-administered and self-managed REIT. As of June 30, 2015, we owned and operated a portfolio of 251 developed properties located in 30 states throughout the United States, including 203 MH communities, 34 RV communities, and 14 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 2014 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".

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.

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 2015 and 2014.  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, 2013 and which we have owned and operated continuously since January 1, 2014.

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 June 30, 2015 and 2014:

⁽¹⁾    Occupied sites and occupancy % include MH and annual RV sites, and exclude transient RV sites, which are included in total developed sites.

⁽²⁾ Occupancy % excludes recently completed but vacant expansion sites.

⁽³⁾  Weighted average rent pertains to annual RV sites and excludes transient RV sites.

The 8.8% growth in NOI is primarily due to increased revenues of $6.1 million partially offset by additional expenses of $1.6 million.

Income from real property revenue consists of MH and RV site rent, and miscellaneous other property revenues.  The 8.2% growth in income from real property is primarily due to increased revenue from our MH and RV portfolio of $5.1 million due to the increased number of occupied home sites and the increase to our weighted average rental rate of 3.2%.  Additionally, transient RV revenue increased $0.5 million and other miscellaneous fees and charges increased by $0.6 million.

Property operating expenses increased approximately $1.6 million, or 6.8%, compared to 2014. Of that increase, payroll and benefits expenses increased $0.7 million primarily due to increased salaries and wages and increased workers compensation costs. Legal, taxes and insurance expenses increased $0.3 million, primarily due to an increase in property and casualty insurance.

SUN COMMUNITIES, INC.

Supplies and repair expenses increased $0.2 million primarily due to increases in landscaping expense, and other expenses increased $0.2 million primarily due to an increase in operational leadership development expense.

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 June 30, 2015 and 2014 (in thousands, except for statistical information):

	Three Months Ended June 30,

Number of sold rental homes	207		220		(13		)	(5.9	)%
Weighted average monthly rental rate, end of period	$	835	$	804	$	31		3.9	%

⁽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 19.6% 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 $0.3 million was primarily a result of increased taxes and insurance expense of $0.3 million due to property and casualty insurance and property tax increases and increased commissions expense of $0.1 million. These expenses were partially offset by a decrease in advertising expense and a decrease in occupied home repairs.

The 8.7% growth in NOI is primarily due to increased revenues of $11.4 million partially offset by an increase in expenses of $2.1 million.

Income from real property revenue consists of MH and RV site rent, and miscellaneous other property revenues.  The 7.4% growth in income from real property is primarily due to increased revenue from our MH and RV portfolio of $9.4 million as a result of the increased number of occupied home sites, and the increase to our weighted average rental rate of 3.2%. Additionally, transient RV revenue increased $1.1 million and other revenues increased by $0.9 million primarily due to an increase in month to month fees, trash income, cable television royalties, application fees, and other charges and fee revenue.

Property operating expenses increased $2.1 million, or 4.6% compared to 2014. Of that increase, salaries and wages, workers compensation costs and health insurance costs increased $1.3 million, legal, taxes and insurance expenses increased $0.5 million primarily due to increased property and casualty insurance, real estate taxes increased $0.2 million, and other miscellaneous expenses increased $0.3 million primarily due to increases in credit card processing charges, corporate advertising and meeting expenses.

⁽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 19.6% 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 $0.6 million was primarily a result of a $0.4 million increase in commissions expense due to the increased number of new leases and taxes and insurance expense of $0.4 million due to increases in property and casualty insurance, property taxes and use tax expense. These increases were partially offset by decreases in repairs and refurbishment expense of $0.1 million due to decreased rental home move out refurbishment costs and a decrease in marketing and other expense of $0.1 million due to a decrease in gas and electric utility costs.

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

Brokerage commissions and other revenues increased primarily due to a $0.6 million increase in brokerage commissions due to the increase in broker home sales, an increase in employee loan interest income of $0.2 million, an increase in cash management interest income of $0.1 million and a decrease in the loan loss reserve of $0.3 million, partially offset by a decrease in income from the sale of property of $0.2 million.

Real property general and administrative expenses increased primarily due to increased salaries, wages and related taxes of $1.4 million, an increase in deferred compensation costs of $1.1 million, an increase in professional accounting services of $0.2 million, an increase of $0.1 million in taxes and insurance expense due to increases in corporate insurance, a $0.1 million increase in both employee benefit expense and legal fees, and increased other expenses of $0.8 million primarily related to increased travel, trainings, directors fees and expenses, dues, licenses and subscriptions, postage and rent expenses.

Home sales and rentals general and administrative expenses increased primarily due to increased salaries, wages and related taxes of $1.0 million, increased commissions costs of $0.4 million, an increase in taxes and insurance expense of $0.1 million due to an increase in open lot insurance and increased other expenses of $0.4 million primarily related to increased seminars and conventions, office and advertising expenses.

Transaction costs increased primarily due to due diligence costs related to the Green Courte and Berger acquisitions (see Note 2).

Depreciation and amortization expenses increased as a result of additional depreciation and amortization of $20.6 million primarily related to our newly acquired properties, $2.6 million related to depreciation on investment property for use in our Rental Program, $0.9 million related to depreciation on homes in our vacation rental program and $2.4 million related to the amortization of in-place leases and promotions.

Extinguishment of debt expenses increased after defeasing total debt of $70.6 million aggregate principal amount of collateralized term loans, releasing 10 communities.

Interest expense on debt, including interest on mandatorily redeemable debt, increased primarily as a result of an $16.6 million increase in mortgage interest due to the acquisition of the Green Courte and Berger properties, a $0.6 million increase in expense associated with our secured borrowing arrangements, a $0.4 increase in our deferred financing costs and a $0.1 million increase in deferred financing cost amortization, partially offset by a decrease of $1.1 million in interest expense on our lines of credit.

SUN COMMUNITIES, INC.

Gain on disposition of properties, net of $8.8 million is a result of the sale of one MH property during the six months ended June 30, 2015 (see Note 2). We disposed of four properties during the six months ended June 30, 2014 resulting in a gain of $0.9 million.

Distributions from affiliate increased $6.7 million as a result of an initial distribution from Origen. We suspended equity accounting in 2010 on our affiliate, Origen, as our investment balance is zero. During 2015, Origen sold substantially all of its assets and commenced a liquidation process. 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.

SUN COMMUNITIES, INC.

LIQUIDITY AND CAPITAL RESOURCES

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

Subject to market conditions, we intend to continue to look for opportunities to expand our development pipeline and acquire existing communities. We also intend to continue to strengthen our capital and liquidity positions by continuing to focus on our core fundamentals, which are generating positive cash flows from operations, maintaining appropriate debt levels and leverage ratios, and controlling overhead costs. We intend to meet our liquidity requirements through available cash balances, cash flows generated from operations, draws on our secured credit facility, and the use of debt and equity offerings under our automatic shelf registration statement.

During the six months ended June 30, 2015, we acquired 34 MH communities and one RV community with approximately 14,300 sites. We also disposed of one MH community with approximately 800 sites. See Note 2 to our financial statements for details on the 2015 acquisitions and dispositions and Note 9 to our financial statements for related debt transactions.  

We will continue to evaluate acquisition opportunities that meet our criteria for acquisition. Should additional investment opportunities arise in 2015, we intend to finance the acquisitions through available cash, secured financing, draws on our credit facilities, the assumption of existing debt on the properties and the issuance of certain equity securities.

During the six months ended June 30, 2015, we invested $15.5 million in the acquisition of homes intended for the Rental Program net of proceeds from third party financing from home sales.  Expenditures for 2015 will depend upon the condition of the markets for repossessions and new home sales, as well as rental homes. We finance new home purchases with a $12.0 million 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):

	Six Months Ended June 30,
	2015			2014
Net Cash Provided by Operating Activities	$	92,393		$	77,113
Net Cash Used in Investing Activities	$	(304,852	)	$	(196,769	)
Net Cash Provided by Financing Activities	$	140,930		$	122,523

Operating Activities

Cash and cash equivalents decreased by $(71.5) million from $83.5 million as of December 31, 2014, to $11.9 million as of June 30, 2015. Net cash provided by operating activities increased by $15.3 million from $77.1 million for the six months ended June 30, 2014 to $92.4 million for the six months ended June 30, 2015.

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 2014 Annual Report.

Investing Activities

Net cash used in investing activities was $304.9 million for the six months ended June 30, 2015, compared to $196.8 million for the six months ended June 30, 2014. The increase is primarily due to increased cash used for the continued acquisition of properties, as well as recurring investment in existing properties.

45

SUN COMMUNITIES, INC.

Financing Activities

Net cash provided by financing activities was $140.9 million for the six months ended June 30, 2015, compared to $122.5 million for the six months ended June 30, 2014. The increase is primarily due to increased net proceeds from other debt and net activity on our line of credit, increased cash used for distributions and preferred returns, and a decrease in the cash provided from the issuance of equity or other securities.

Financial Flexibility

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%. We had $33.1 million outstanding as of June 30, 2015 and no amount outstanding as of December 31, 2014 under the Facility.

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 June 30, 2015, we had outstanding letters of credit to back standby letters of credit totaling approximately $3.2 million, leaving approximately $313.7 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 June 30, 2015
Maximum Leverage Ratio	<68.5%	46.6%
Minimum Fixed Charge Coverage Ratio	>1.40	2.34
Minimum Tangible Net Worth	>$990,159	$2,234,471
Maximum Dividend Payout Ratio	<95.0%	78.0%

Market and Economic Conditions

The U.S. rate environment, monetary policy change in China, Japan and the Euro area, falling oil prices and turmoil in emerging markets are factors that are influencing financial markets in 2015.  Questions still exist on whether the U.S. economy will sustain the growth indicators it has reported and whether or when the U.S. Federal Reserve will increase its benchmark rate for the first time in 10 years, as well as how Japan and the Eurozone will recover amidst easing monetary policy. Whether or not China falls into a recession amidst a stock market downturn and what the effect of additional global turmoil will have on the world economy keep economic outlooks tempered. While the U.S. economy looks poised for self-sustaining growth, the global economy is seeing modest improvement led by developed countries. Continued economic uncertainty, both nationally and internationally, causes increased volatility in investor confidence thereby creating similar volatility in the availability of both debt and equity capital. If such volatility is experienced in future periods, our industry, business and results of operations may be adversely impacted.

We anticipate meeting our long-term liquidity requirements, such as scheduled debt maturities, large property acquisitions, and Operating Partnership unit redemptions through the issuance of certain debt or equity securities and/or the collateralization of our properties. At June 30, 2015, we had 83 unencumbered properties with an estimated market value of $857.2 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 2014 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.

46

SUN COMMUNITIES, INC.

As of June 30, 2015, our net debt to enterprise value approximated 38.0%(assuming conversion of all common OP units, A-1 preferred OP units, A-3 preferred OP units and A-4 preferred OP units and Series C units to shares of common stock). Our debt has a weighted average maturity of approximately 7.9 years and a weighted average interest rate of 5.1%.

Capital expenditures for the six months ended June 30, 2015 and 2014 included recurring capital expenditures of $7.7 million and $4.0 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 2015.

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 $160.1 million as of June 30, 2015. The first interest rate cap agreement has a cap rate of 9.00%, a notional amount of $150.1 million and a termination date of April 2018. The second interest rate cap agreement has a cap rate of 11.02%, a notional amount of $10.0 million and a termination date of October 2016.

Our remaining variable rate debt totals $197.3 million and $273.4 million as of June 30, 2015 and 2014, respectively, and bears interest at Prime or various LIBOR rates. If Prime or LIBOR increased or decreased by 1.0%, we believe our interest expense would have increased or decreased by approximately $1.7 million and $3.4 million as of June 30, 2015 and 2014, respectively, based on the $167.7 million and $341.9 million average balances outstanding under our variable rate debt facilities, respectively.

ITEM 4.  CONTROLS AND PROCEDURES

Evaluation of disclosure controls and procedures

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

Changes in internal control over financial reporting

There have been no changes in our internal control over financial reporting during the quarterly period ended June 30, 2015 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 April 2015, the FASB issued ASU No. 2015-03, "Simplifying the Presentation of Debt Issuance Costs," ("ASU 2015-03"). ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The standard is effective for annual reporting periods beginning after December 15, 2015, and interim periods within those years, with early adoption permitted. We are currently evaluating the potential impact the new standard will have on our consolidated financial statements.

In February 2015, the FASB issued ASU No. 2015-02, "Amendments to the Consolidation Analysis," ("ASU 2015-02"). ASU 2015-02 eliminates the deferral of FAS 167, which has allowed entities with interests in certain investment funds to follow the previous consolidation guidance in FIN 46(R), and makes other changes to both the variable interest model and the voting model. While the guidance is aimed at asset managers, it will affect all reporting entities that have variable interests in other legal entities (e.g., limited partnerships, similar entities and certain corporations). In some cases, consolidation conclusions will change. In other cases, reporting entities will need to provide additional disclosures about entities that currently aren’t considered VIEs but will be considered VIEs under the new guidance provided they have a variable interest in those VIEs. The standard is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015, with early adoption permitted. We are currently evaluating the potential impact the new standard will have on our consolidated financial statements.

Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]

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. Certain reclassifications have been made to prior periods' financial statements in order to conform to current period presentation.

The results of operations for interim periods are not necessarily indicative of results that may be expected for any other interim period or for the full year. These 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, 2014 as filed with the SEC on March 2, 2015 (the “2014 Annual Report”). These statements have been prepared on a basis that is substantially consistent with the accounting principles applied in our 2014 Annual Report.

Reference in this report to Sun Communities, Inc., “we”, “our”, “us” and the “Company” refer to Sun Communities, Inc. and its subsidiaries, unless the context indicates otherwise.

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.

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.

16.   Fair Value of Financial Instruments, continued

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 require disclosure of their fair values on a recurring basis and presents the carrying values and fair values as of June 30, 2015 and December 31, 2014 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.

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.

Collateralized Term Loans

In January 2015, in relation to the acquisition of the Green Courte properties (see Note 2), we refinanced approximately $90.8 million of mortgage debt on 10 of the communities (resulting in proceeds of $112.3 million) at a weighted average interest rate of 3.87% per annum and a weighted average term of 14.1 years. We also assumed approximately $201.4 million of mortgage debt at a weighted average interest rate of 5.74% and a weighted average remaining term of 6.3 years.

In March 2015, in relation to the acquisition of Meadowlands (see Note 2), we assumed a $6.3 million mortgage with an interest rate of 6.5% and a remaining term of 6.5 years. Also, in relation to this acquisition, we entered into a note with the seller for $2.4 million that bears no interest but is payable in three equal yearly installments beginning in March 2016.

In April 2015, in relation to the acquisition of the Berger properties (see Note 2), we assumed debt with a fair market value of $169.9 million on the communities with a weighted average interest rate of 5.17% and a weighted average remaining term of 6.3 years.

In May 2015, we defeased a total of $70.6 million aggregate principal amount of collateralized term loans with an interest rate of 5.32% that were due to mature on July 1, 2016, releasing 10 communities. As a result of the transaction we recognized a loss on debt extinguishment of $2.8 million that is reflected in our consolidated statement of operations.

The collateralized term loans totaling $2.2 billion as of June 30, 2015, are secured by 168 properties comprised of 59,451 sites representing approximately $2.6 billion of net book value.

Preferred OP Units

Included in Preferred OP units is $34.7 million of Aspen preferred OP units issued by the Operating Partnership which are convertible into 509,676 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 distribution rate is 6.5%.

Secured Borrowing

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

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 June 30, 2015, the margin was 1.70%. We had $33.1 million outstanding as of June 30, 2015, with an effective interest rate of 2.71%, and no amount outstanding as of December 31, 2014 under the Facility. At June 30, 2015 and December 31, 2014, approximately $3.2 million 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 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 June 30, 2015, the effective interest rate was 7.0%.  The outstanding balance was $4.6 million and $5.8 million at June 30, 2015 and December 31, 2014, 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 June 30, 2015, we were in compliance with all covenants.

Equity Transactions

Equity and Mezzanine Securities

In June 2015, we issued to GCP Fund III Ancillary Holding, LLC (i) 25,664 shares of common stock at an issuance price of $50.00 per share or $1,283,200 in the aggregate, and (ii) 34,219 shares of 6.50% Series A-4 Cumulative Convertible Preferred Stock at an issuance price of $25.00 per share, or $855,475 in the aggregate. All of these common shares and preferred shares were issued for cash consideration pursuant to the terms of a Subscription Agreement, dated July 30, 2014 , as amended, among the Company, Green Court Real Estate Partners III, LLC, and certain other parties. The parties have agreed that no additional securities are issuable under the Subscription Agreement.

Also in June 2015, we entered into an At the Market Offering Sales Agreement (the "Sales Agreement") with BMO Capital Markets Corp., Merrill Lynch, Pierce, Fenner and Smith Incorporated and Citigroup Global Markets Inc. (collectively, the "Sales Agents"). Pursuant to the Sales Agreement, we may offer and sell shares of our common stock, having an aggregate offering price of up to $250.0 million, from time to time through the Sales Agents. Each Sales Agent is entitled to compensation in an agreed amount not to exceed 2.0% of the gross sales price per share for any shares sold through it from time to time under the Sales Agreement. Concurrently, the At the Market Offering Sales Agreement dated May 10, 2012, as amended among the Company, the Partnership, BMO Capital Markets Corp. and Liquidnet, Inc., was terminated. In the three months ended June 30, 2015, we issued 26,200 common shares under the Sales Agreement, at a sales price of $65.15 for net proceeds of $1.7 million.

Prior to the termination of the At the Market Offering Sales Agreement dated May 10, 2012, in the three months ended March 31, 2015, 342,011 shares of common stock were issued at the prevailing market price of our common stock at the time of each sale with a weighted average sale price of $63.94, and we received net proceeds of approximately $21.5 million.

In April 2015, in connection with the Berger acquisition, we issued 371,808 common OP units at an issuance price of $61.00 per share and 340,206 newly created Series C preferred OP units at an issuance price of $100.00 per share. The Series C preferred OP unit holders receive a preferred return of 4.0% per year from the closing until the second anniversary of the date of issuance, 4.5% per year during the following three years, and 5.0% per year thereafter. At the holder’s option, each Series C preferred OP unit will be exchangeable into 1.11 shares of the Company’s common stock and holders of Series C preferred OP units do not have any voting or consent rights.

In January 2015, in connection with the Green Courte second closing, we issued 4,377,073 shares of common stock at an issuance price of $50.00 per share and 5,847,234 shares of Series A-4 Preferred Stock at an issuance price of $25.00 per share. The Series A-4 Preferred Stock holders receive a preferred return of 6.5%. In addition, one of the Green Courte Partners funds purchased 150,000 shares of our common stock and 200,000 Series A-4 preferred OP units for an aggregate purchase price of $12.5 million.

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 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 $133.1 million (net of allowance of $0.6 million) and $123.0 million (net of allowance of $0.7 million) as of June 30, 2015 and December 31, 2014, respectively.  The outstanding balance on the secured borrowing was $133.7 million and $123.7 million as of June 30, 2015 and December 31, 2014, respectively.

The balances of the collateralized receivables and secured borrowings fluctuate. The balances increase as additional notes receivable are transferred and exchanged for cash proceeds. The balances are reduced as the related collateralized receivables are collected from the customers, or as the underlying collateral is repurchased. The change in the aggregate gross principal balance of the collateralized receivables is as follows (in thousands):

	Six Months Ended
	June 30, 2015
Beginning balance	$	123,650
Financed sales of manufactured homes	18,175
Principal payments and payoffs from our customers	(3,857		)
Principal reduction from repurchased homes	(4,222		)
Total activity	10,096
Ending balance	$	133,746

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 $3.3 million and $2.9 million and $6.3 million and $5.6 million for the three and six months endedJune 30, 2015 and 2014, respectively.

Derivative Instruments And Hedging Activities

Derivative Instruments and Hedging Activities

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

The following table provides the terms of our interestrate derivative contracts that were in effect as of June 30, 2015:

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

Share-based Compensation [Abstract]

Share-Based Compensation

Share-Based Compensation

In May 2015, we granted 25,000 shares of restricted stock to an executive officer under our Sun Communities, Inc. Equity Incentive Plan ("2009 Equity Plan"). The shares had a fair value of $62.94 per share and will vest as follows: May 19, 2018: 35%; May 19, 2019: 35%; May 19, 2020: 20%; May 19, 2021: 5%; and May 19, 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 April 2015, we granted 145,000 shares of restricted stock to our executive officers under our 2009 Equity Plan. The shares had a fair value of $63.81 per share. Half of the shares are subject to time vesting as follows: April 14, 2018: 20%; April 14, 2019: 30%; April 14, 2020: 35%; April 14, 2021: 10%; and April 14, 2022: 5%. The remaining 72,500 shares are subject to market and performance conditions which vest over time through April 2020. Share-based compensation for restricted stock awards with performance conditions is measured based on an estimate of shares expected to vest. We estimate the fair value of share-based compensation for restricted stock with market conditions using a Monte Carlo simulation.

In February 2015, we granted 19,800 shares of restricted stock to our non-employee directors under our First Amended and Restated 2004 Non-Employee Director Option Plan. The awards vest on February 11, 2018, and had a fair value of $65.87 per share. The fair value was determined by using the closing share price of our common stock on the date the shares were issued.

In January 2015, we granted 1,000 shares of restricted stock to key employees under our 2009 Equity Plan. The restricted shares had a fair value of $65.48 per share and will vest as follows: January 8, 2018: 35%; January 8, 2019: 35%; January 8, 2020: 20%;

January 8, 2021: 5%; and January 8, 2022: 5%. The fair value was determined by using the closing share price of our common stock on the date the shares were issued.

During the six months ended June 30, 2015 and 2014, 4,084 and 4,904 shares of common stock, respectively, were issued in connection with the exercise of stock options, and the net proceeds received during both periods were $0.1 million.

At June 30, 2015 and December 31, 2014, 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%. We had suspended equity accounting for this investment as the carrying value of our investment was zero. In January 2015, Origen completed the sale of substantially all of its assets to an affiliate of GoldenTree Asset Management LP and has announced its intention to dissolve and liquidate. During the second quarter of 2015, and as disclosed in a press release on March 30, 2015, Origen made an initial distribution of $1.50 per share to its stockholders of record as of April 13, 2015, retaining approximately $6.2 million for expected dissolution and wind down costs and expenses and contingencies. Depending on the actual cost of estimated wind down expenses, Origen may make one or more additional interim distributions of excess cash to stockholders prior to completing liquidation. Upon completion of liquidation, Origen will distribute remaining cash, if any, to stockholders. During the three months ended June 30, 2015, we received an initial distribution of $7.5 million from Origen.

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

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

We have elected to be taxed as a real estate investment trust (“REIT”) pursuant to Section 856(c) of the Internal Revenue Code of 1986 (“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 (i.e., some on an annual and quarterly basis) established under highly technical and complex Code provisions for which there are only limited judicial or administrative interpretations, and involves the determination of various factual matters and circumstances not entirely within our control. In addition, frequent changes occur in the area of REIT taxation which requires us to continually monitor our tax status. We analyzed the various REIT tests and confirmed that we continued to qualify as a REIT for the quarter ended June 30, 2015.

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 June 30, 2015 and December 31, 2014.

We had no unrecognized tax benefits as of June 30, 2015 and 2014. We expect no significant increases or decreases in unrecognized tax benefits due to changes in tax positions within one year of June 30, 2015.

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 June 30, 2015 and the three and six months ended June 30, 2014, and $0.2 million for the six months ended June 30, 2015.

SHS is currently under examination by the Internal Revenue Service ("IRS") for tax year 2013. To date, we have not received any formal notices of proposed adjustments from the IRS related to this or any other examination periods.

⁽¹⁾The purchase price allocations for the first and second closings are preliminary and may be adjusted as final costs and final valuations are determined.

⁽²⁾ To estimate the fair value of the common OP units at the valuation date, we utilized the market approach, observing public price of our common stock.

⁽³⁾ To estimate the fair value of the Series A-4 preferred OP units and the Series A-4 Preferred Stock at the valuation date, we utilized an income approach. Under this approach, we used the Binomial Lattice Method.

The following unaudited pro forma financial information presents the results of our operations for the three and six months ended June 30, 2015 and 2014 as if the properties were acquired on January 1, 2014. 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, 2014 (in thousands, except per-share data).

Transaction costs of approximately $2.0 million and $1.1 million and $11.5 million and $1.9 million have been incurred for the three and six months ended June 30, 2015 and 2014, respectively, and are presented as “Transaction costs” in our consolidated statements of operations.

Dispositions

During January 2015, we completed the sale of Valley Brook, a MH community located in Indiana. Pursuant to Accounting Standards Update ("ASU") 2014-08, "Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity" ("ASU 2014-08"), the disposal of the community does not qualify for presentation as a discontinued operation, as the sale does not have a major impact on our operations and financial results and does not represent a strategic shift. Additionally, the community is not considered an individually significant component and therefore does not qualify for presentation as a discontinued operation. A gain of $8.8 million is recorded in "Gain on disposition of properties, net" in our consolidated statements of operations.

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 $35.8 million annually. This transient revenue was recognized 24.5% and 19.2% in the first and second quarters, respectively, and is expected to be recognized 42.6% in the third quarter and 13.7% in the fourth quarter of 2015. In 2014, transient revenue was $31.6 million and was recognized 25.3% in the first quarter, 18.3% in the second quarter, 43.3% in the third quarter and 13.1% in the fourth quarter.

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