Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	Summary of Significant Accounting Policies
	Business
	Sun Communities, Inc., a Maryland corporation, together with the Sun Communities Operating Limited Partnership, a Michigan limited partnership (the “Operating Partnership”) and other consolidated subsidiaries are referred to herein as the “Company”, “us”, “we”, and “our”. We are a self-administered and self-managed real estate investment trust (“REIT”).
	We own, operate, and develop manufactured housing ("MH") and recreational vehicle ("RV") communities throughout the United States. As of December 31, 2014, we owned and operated a portfolio of 217 properties located in 29 states (the “Properties”), including 183 MH communities, 25 RV communities, and nine properties containing both MH and RV sites. As of December 31, 2014, the Properties contained an aggregate of 79,554 developed sites comprised of 61,231 developed manufactured home sites, 9,297 annual RV sites (inclusive of both annual and seasonal usage rights), 9,026 transient RV sites, and approximately 7,000 additional MH and RV sites suitable for development.
	Principles of Consolidation
	The accompanying financial statements include our accounts and all majority-owned and controlled subsidiaries, including entities in which we have a controlling interest or have been determined to be the primary beneficiary of a variable interest entity ("VIE"). All inter-company transactions have been eliminated in consolidation. Any subsidiaries in which we have an ownership percentage equal to or greater than 50%, but less than 100%, or consider a VIE, represent subsidiaries with a noncontrolling interest. The noncontrolling interests in our subsidiaries are allocated their proportionate share of the subsidiaries’ financial results. This allocation is recorded as the noncontrolling interest in our consolidated financial statements.
	Use of Estimates
	The preparation of financial statements in conformity with generally accepted accounting principles in the United States (“GAAP”) requires management to make estimates and assumptions related to the reported amounts included in our consolidated financial statements and accompanying footnote disclosures. Actual results could differ from those estimates.
	Reclassifications and Revisions
	Certain reclassifications have been made to prior periods’ financial statements in order to conform to current period presentation.
	In the fourth quarter of 2014, management identified that certain accruals related to real estate taxes, deferred revenue and utilities primarily associated with communities acquired prior to 2007 were incorrect.  The cumulative reivison for the incorrect accruals approximated $13.5 million.
	Pursuant to the guidance of Staff Accounting Bulletin (“SAB”) No. 99, Materiality, the Company concluded that the errors were not material to any of its prior period financial statements. Although the errors were immaterial to prior periods, the prior period financial statements were revised, in accordance with SAB No. 108, Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements, due to the significance of the out-of-period correction in the fourth quarter of 2014.

	Noncontrolling interests, revised		$	15,223		$	19,124		$	24,610
	Investment Property
	Investment property is recorded at cost, less accumulated depreciation. We review the carrying value of long-lived assets to be held and used for impairment quarterly or whenever events or changes in circumstances indicate a possible impairment.Our primary indicator for potential impairment is based on NOI trends period over period. Circumstances that may prompt a test of recoverability may include a significant decrease in the anticipated market price, an adverse change to the extent or manner in which an asset may be used or in its physical condition or other such events that may significantly change the value of the long-lived asset. An impairment loss is recognized when a long-lived asset’s carrying value is not recoverable and exceeds estimated fair value. We estimate the fair value of our long-lived assets based on discounted future cash flows and any potential disposition proceeds for a given asset. Forecasting cash flows requires management to make estimates and assumptions about such variables as the estimated holding period, rental rates, occupancy and operating expenses during the holding period, as well as disposition proceeds. Management uses its best judgment when developing these estimates and assumptions, but the development of the projected future cash flows is based on subjective variables. Future events could occur which would cause us to conclude that impairment indicators exist, and significant adverse changes in national, regional, or local market conditions or trends may cause us to change the estimates and assumptions used in our impairment analysis. The results of an impairment analysis could be material to our financial statements.
	1	Summary of Significant Accounting Policies, continued
	We periodically receive offers from interested parties to purchase certain of our properties. These offers may be the result of an active program initiated by us to sell the property, or from an unsolicited offer to purchase the property. The typical sale process involves a significant negotiation and due diligence period between us and the potential purchaser. As the intent of this process is to determine if there are items that would cause the purchaser to be unwilling to purchase or we would be unwilling to sell, it is not unusual for such potential offers of sale/purchase to be withdrawn as such issues arise. We classify assets as “held for sale” when it is probable, in our opinion, that a sale transaction will be completed within one year. This typically occurs when all significant contingencies surrounding the closing have been resolved, which often corresponds with the closing date.
	We allocate the purchase price of properties to net tangible and identified intangible assets acquired based on their fair values. In making estimates of fair values for purposes of allocating purchase price, we utilize an independent third party to value the net tangible and identified intangible assets in connection with the acquisition of the respective property. We provide historical and pro forma financial information obtained about each property, as well as any other information needed in order for the third party to ascertain the fair value of the tangible and intangible assets (including in-place leases) acquired.
	Other Capitalized Costs
	We capitalize certain costs incurred in connection with the development, redevelopment, capital enhancement and leasing of our properties. Management is required to use professional judgment in determining whether such costs meet the criteria for immediate expense or capitalization. The amounts are dependent on the volume and timing of such activities and the costs associated with such activities. Maintenance, repairs and minor improvements to properties are expensed when incurred. Renovations and improvements to properties are capitalized and depreciated over their estimated useful lives and construction costs related to the development of new community or expansion sites are capitalized until the property is substantially complete. Costs incurred to initially renovate pre-owned and repossessed homes that we acquire for our Rental Program are capitalized and costs incurred to refurbish the homes at turnover and repair the homes while occupied are expensed. Certain expenditures to dealers and residents related to obtaining lessees in our communities are capitalized and amortized over a seven year period based on the anticipated term of occupancy of a resident. Costs associated with implementing our computer systems are capitalized and amortized over the estimated useful lives of the related software and hardware. Costs incurred to obtain new financing are capitalized and amortized over the terms of the related loan agreement using the straight-line method (which approximates the effective interest method).
	Cash and Cash Equivalents
	We consider all highly liquid investments with a maturity of three months or less from the date of purchase to be cash and cash equivalents. The maximum amount of credit risk arising from cash deposits in excess of federally insured amounts was approximately $80.7 million and $5.7 million as of December 31, 2014 and 2013, respectively. From time to time, we may have cash deposits in excess of federally insured amounts.
	Inventory
	Inventory of manufactured homes is stated at lower of specific cost or market based on the specific identification method.
	Investments in Affiliates
	Investments in affiliates in which we do not have a controlling direct or indirect voting interest, but can exercise significant influence over the entity with respect to its operations and major decisions, are accounted for using the equity method of accounting. The carrying value of our investment is adjusted for our proportionate share of the affiliate’s net income or loss and reduced by distributions received. We review the carrying value of our investment in affiliates for other than temporary impairment whenever events or changes in circumstances indicate a possible impairment. Financial condition, operational performance, and other economic trends are some of the factors we consider when we evaluate the existence of impairment indicators. When we have a carrying value of zero for our investment, we suspend the equity method of accounting until such time that the affiliate’s net income equals or exceeds the share of net losses not recognized during the time in which the equity method of accounting was suspended. See Note 7 for additional information.

	Notes and Other Receivables
	We provide financing to purchasers of manufactured homes generally located in our communities. The notes are collateralized by the underlying manufactured home sold. Notes receivable include both installment loans retained by the Company as well as transferred loans that have not met the requirements for sale accounting which are presented herein as collateralized receivables (See Note 5 for additional information). For purposes of accounting policy, all notes receivable are considered one homogenous population, as the notes are typically underwritten using the same requirements and terms. Notes receivable are reported at their outstanding unpaid principal balance adjusted for an allowance for loan loss. Interest income is accrued based upon the unpaid principal balance of the loans.
	Past due status of our notes receivable is determined based upon the contractual terms of the note. When a note receivable becomes 60 days delinquent, we stop accruing interest on the note receivable. The interest on nonaccrual loans is accounted for on the cash
	basis until qualifying for return to accrual. Loans are returned to accrual when all principal and interest amounts contractually due are brought current and future payments are reasonably assured. Loans on a nonaccrual status were immaterial at December 31, 2014 and 2013. The ability to collect our notes receivable is measured based on current and historical information and events. We consider numerous factors including: length of delinquency, estimated costs to lease or sell, and repossession history. Our experience supports a high recovery rate for notes receivable; however there is some degree of uncertainty about the recoverability of our investment in these notes receivable. We are generally able to recover our recorded investment in uncollectible notes receivable by repossessing the homes on the notes retained by us and repurchasing the homes on the collateralized receivables, and subsequently selling or leasing these homes to potential residents in our communities. We have established a loan loss reserve based on our estimated unrecoverable costs associated with repossessed/repurchased homes. We estimate our unrecoverable costs to be the repurchase price of the home collateralizing the note receivable plus repair and remarketing costs in excess of the estimated selling price of the home being repossessed. A historical average of this excess cost is calculated based on prior repossessions/repurchases and is applied to our estimated annual future repossessions to create the allowance for both installment and collateralized notes receivable. See Note 5 for additional information.
	We evaluate the collectability of a loan based on our ability to collect the scheduled payments of principal and interest when due according to the contractual terms of the loan agreement. We generally see that if the obligor is delinquent on the loan they are also delinquent on site rent. If the scheduled payment is delinquent more than five to seven days, dependent on state law, we begin the repossession and eviction process simultaneously. This process generally takes 30 to 45 days; due to the short time frame from delinquent loan to repossession we do not evaluate the note receivables for impairment. No loans were considered impaired as of December 31, 2014 and 2013.
	We evaluate the credit quality of our notes receivable at the inception of the receivable. We consider the following factors in order to determine the credit quality of the applicant - rental payment history; home debt to income ratio; total debt to income ratio; length of employment; previous landlord references; and credit scores.
	Other receivables are generally comprised of amounts due from residents for rent and related charges, home sale proceeds receivable from sales near year end and various other miscellaneous receivables. Accounts receivable from residents are typically due within 30 days and stated at amounts due from residents net of an allowance for doubtful accounts. Accounts outstanding longer than the contractual payment terms are considered past due. We evaluate the recoverability of our receivables whenever events occur or there are changes in circumstances such that management believes it is probable that it will be unable to collect all amounts due according to the contractual terms of the loan and lease agreements. Receivables related to community rents are reserved when we believe that collection is less than probable, which is generally after a resident balance reaches 60 to 90 days past due.
	Restricted Cash
	Restricted cash consists of amounts held in deposit at a financial institution to collateralize derivative instruments in a liability position and deposits for tax, insurance and repair escrows held by lenders in accordance with certain debt agreements. At December 31, 2014 and 2013, $11.8 million and $9.4 million of restricted cash, respectively, was included as a component of Other assets on the consolidated balance sheets.
	1	Summary of Significant Accounting Policies, continued
	Identified Intangible Assets
	The Company amortizes identified intangible assets that are determined to have finite lives over the period the assets are expected to contribute directly or indirectly to the future cash flows of the property or business. At December 31, 2014 and 2013, the carrying amounts of the identified intangible assets are included in Other assets on the consolidated balance sheets. See Note 6 for additional information on our intangible assets.
	Deferred Tax Assets
	We are subject to certain state taxes that are considered to be income taxes and have certain subsidiaries that are taxed as regular corporations. Deferred tax assets or liabilities are recognized for temporary differences between the tax basis of assets and liabilities and their carrying amounts in the financial statements and net operating loss carryforwards. Deferred tax assets and liabilities are measured using currently enacted tax rates. A valuation allowance is established if, based on the available evidence, it is considered more likely than not that some portion or all of the deferred tax assets will not be realized. See Note 13 for additional information.
	Deferred Financing Costs
Deferred financing costs include fees and costs incurred to obtain long-term financing. The costs are amortized over the terms of the respective loans. Unamortized deferred financing costs are written off when debt is retired before the maturity date. Upon amendment of the line of credit or refinancing of mortgage debt, unamortized deferred financing costs are accounted for in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 470-50-40, Modifications and Extinguishments. At December 31, 2014 and 2013, deferred financing costs are included as a component of Other assets on the consolidated balance sheets.
Share-Based Compensation
Share-based compensation cost for service vesting restricted stock awards is measured based on the closing share price of our common stock on the date of grant. Share-based compensation for restricted stock awards with performance conditions is measured based on an estimate of shares expected to vest. If it is not probable that the performance conditions will be satisfied, we do not recognize compensation expense. We measure the fair value of awards with performance conditions using the closing price of our common stock as of the grant date to calculate compensation cost. Each reporting period, we reevaluate our estimate of the number 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. We recognize compensation cost ratably over each tranche of shares based on the fair value estimated by the model.
Share-based compensation cost for stock options is estimated at the grant date based on each option’s fair-value as calculated by the Binomial (lattice) option-pricing model. The Binomial (lattice) option-pricing model incorporates various assumptions including expected volatility, expected life, dividend yield, and interest rates. See Note 11 for additional information.
Fair Value of Financial Instruments
Our financial instruments consist of cash and cash equivalents, accounts and notes receivable, accounts payable, derivative instruments, and debt. We utilize fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures, pursuant to FASB ASC 820, Fair Value Measurements and Disclosures.  See Note 17 for additional information regarding the estimates and assumptions used to estimate the fair value of each class of financial instrument.
Revenue Recognition
Rental income attributable to site and home leases is recorded on a straight-line basis when earned from tenants. Leases entered into by tenants are generally for one year terms but may range from month-to-month to two years and are renewable by mutual agreement from us and the resident, or in some cases, as provided by state statute. Revenue from the sale of manufactured homes is recognized upon transfer of title at the closing of the sales transaction. Interest income on notes receivable is recorded on a level yield basis over the life of the notes. We report certain taxes collected from the resident and remitted to taxing authorities in revenue. These taxes include certain Florida property and fire taxes.
1	Summary of Significant Accounting Policies, continued
Advertising Costs
Advertising costs are expensed as incurred. As of December 31, 2014, 2013 and 2012, we had advertising costs of $3.2 million, $2.9 million and $2.5 million, respectively.
Depreciation and Amortization
Depreciation and amortization are computed on a straight-line basis over the estimated useful lives of the assets. Useful lives are 30 years for land improvements and buildings, 10 years for rental homes, seven to 15 years for furniture, fixtures and equipment, and seven to 15 years for intangible assets.
Derivative Instruments and Hedging Activities
We do not enter into derivative instruments for speculative purposes. We adjust our balance sheet on a quarterly basis to reflect the current fair market value of our derivatives. For those hedges that qualify for cash flow hedge accounting, we adjust our balance sheet on a quarterly basis to reflect current fair market value of our derivatives. Changes in the fair value of derivatives are recorded in earnings or comprehensive income, as appropriate. The ineffective portion of the hedge is immediately recognized in earnings to the extent that the change in value of a derivative does not perfectly offset the change in value of the instrument being hedged. The effective portion of the hedge is recorded in accumulated other comprehensive income. We use standard market conventions to determine the fair values of derivative instruments, including the quoted market prices or quotes from brokers or dealers for the same or similar instruments. All methods of assessing fair value result in a general approximation of value and such value may never actually be realized. See Note 16 for additional information. Cash flows from derivative instruments are classified in the same category as the cash flows of the underlying hedged items, which are in the operating activities section of the consolidated statements of cash flows.

Dispositions
During the year ended December 31, 2014, we completed the sales of 10 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 $17.7 million is recorded in "Gain on disposition of properties, net" in our consolidated statement of operations.

	During 2014, we recorded an impairment charge 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.

Transfers and Servicing [Abstract]
Transfers of Financial Assets	Transfers of Financial Assets
	We completed various transactions with an unrelated entity involving our notes receivable during 2014 and 2013 under which we received a total of $35.0 million and $34.0 million, respectively, of 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 as a transfer of financial assets. 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 %
	Less 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	%

	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 $123.0 million (net of allowance of $0.7 million) and $109.8 million (net of allowance of $0.7 million) as of December 31, 2014 and December 31, 2013, respectively.  The outstanding balance on the secured borrowing was $123.7 million and $110.5 million as of December 31, 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):
		Year Ended

	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 $11.8 million, $10.6 million and $9.4 million for the years ended December 31, 2014, 2013 and 2012, respectively.

	Origen Financial Services, LLC (“OFS LLC”)
	At December 31, 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 19.0%. 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 did, however, receive distributions of $1.2 million on our shares of Origen common stock during 2014. Our investment in Origen had a market value of approximately $8.2 million based on a quoted market closing price of $1.64 per share as reported on the OTC Pink Marketplace as of December 31, 2014.
	In January 2015, Origen announced that it completed the sale of substantially all of its assets to an affiliate of GoldenTree Asset Management LP. Origen also announced that it has entered into a letter of intent with Mack Real Estate Credit Strategies, ("MRECS"), an affiliate of Mack Real Estate Group, for a proposed transaction pursuant to which MRECS and other third parties would invest additional capital into Origen by purchasing shares of newly issued common stock. Origen would continue to operate its business as a mortgage REIT and would be externally managed pursuant to a market based management agreement with MRECS. Under the letter of intent, it is anticipated that Origen's stockholders would be given the option to: (a) tender their shares to Origen for cash in an amount equal to Origen's estimated current net cash value, payable at the conclusion of the tender period, or (b) retain their shares in Origen. Origen’s Board of Directors approved the letter of intent and, as permitted by the plan of dissolution approved by Origen’s stockholders in October 2014, Origen has abandoned the plan of dissolution and the distribution of its remaining cash net of expenses and reserves pending completion of the transaction with MRECS. The MRECS transaction is subject to the further negotiation and execution of definitive transaction documents, MRECS’s satisfactory completion of its due diligence on Origen, and other customary closing conditions.

	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, LLC ("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.
	In December 2014, we assumed a mezzanine loan in the amount of $17.7 million, in connection with the Green Courte acquisition, and also assumed a property management agreement to manage and operate the Wildwood community.
	In November 2012, we guaranteed certain non-recourse carveouts under a $45.9 million mortgage loan (the “Senior Loan”) from Ladder Capital Finance LLC to the Rudgate Borrowers. The Senior Loan is secured by the two MH communities that we manage but do not own, which are located in southeast Michigan. In addition, we entered into a mezzanine loan agreement with the sole members of the Rudgate Borrowers under which we agreed to provide mezzanine financing in the amount of $15.1 million in respect of the two MH communities managed by us, and entered into property management agreements to manage and operate these two communities.
	Included in our consolidated financial statements after appropriate eliminations were amounts related to the VIEs at December 31, 2014 and December 31, 2013 as follows (in thousands):

	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 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.
	In December 2013, we and nine of our subsidiaries entered into a loan agreement with a lender for a $72.4 million term loan ("Pool A Loan"), and we and nine of our other subsidiaries entered into a loan agreement with the same lender for a $69.1 million term loan ("Pool B Loan", and collectively with the Pool A Loan, the "Loans"). The Loans mature on January 1, 2024. The Pool A Loan accrues interest at 4.89% per year and is secured by eight MH communities and two RV communities. The Pool B Loan accrues interest at 4.90% per year and is secured by eight MH communities and one RV community. We used the proceeds of the Loans and $34.4 million of additional cash to repay in full 11 loans previously made to subsidiaries of the Company.
	In October 2013, we paid off maturing loans totaling $5.8 million, which were secured by two properties, Dutton Mills and Falcon Pointe.
	In May 2013, we extended until May 1, 2023, $151.4 million of FNMA debt, which had an original maturity date of May 1, 2013. The current weighted average interest rate on this debt is 3.6%.

	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 December 31, 2014, the margin was 1.65%. At December 31, 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 December 31, 2014 and 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.
	In February 2013, we entered into a $61.5 million credit agreement to fund a portion of the purchase of the Morgan RV Properties acquisition (see Note 2 "Real Estate Acquisitions and Dispositions"). This loan was paid off in March 2013.
	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 December 31, 2014 and 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 at least twelve months’ notice of its intent to terminate the agreement. The interest rate is 100 basis points over the greater of the prime rate published in the Wall Street Journal on the first business day of each month or 6.0%. At December 31, 2014 the effective interest

Net proceeds from the offering were approximately $348.9 million after deducting expenses related to the offering. We used the majority of the net proceeds of the offering to fund the cash portion of the purchase price for the acquisition of MH communities from the Green Courte entities (see Note 2) and used the remainder of the net proceeds from the offering to repay borrowings outstanding under the Facility.
	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.

	In February 2013, we issued $4.0 million of Series A-3 preferred OP units in connection with the Morgan RV Properties acquisition (see Note 2).

	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 2014 or 2013.  There is no expiration date specified for the repurchase program.
	Common OP Unit holders can convert their Common OP units into an equivalent number of shares of common stock at any time.  During 2014, holders of Common OP units converted 9,110 units into common stock. No units were converted into common stock during 2013.
	Series A-1 preferred OP unit holders can convert their preferred OP units into 2.439 shares of our common stock (which exchange rate is subject to adjustment upon stock splits, recapitalizations and similar events) at any time. During 2014, holders of Series A-1 preferred OP units converted 26,379 units into 64,335 shares of common stock. No Series A-1 preferred OP units were converted into common stock during 2013.

Share-based Compensation [Abstract]
Share-Based Compensation	Share-Based Compensation
	As of December 31, 2014, we have two share-based compensation plans approved by stockholders: Sun Communities, Inc. Equity Incentive Plan (“2009 Equity Plan”) and the First Amended and Restated 2004 Non-Employee Director Option Plan (“Director Plan”). We believe granting equity awards will provide certain executives, key employees and directors additional incentives to promote our financial success, and promote employee and director retention by providing an opportunity to acquire or increase the direct proprietary interest of those individuals in our operations and future.
	2009 Equity Plan
	The 2009 Equity Plan was approved by our stockholders at the Annual Meeting of Stockholders held on July 29, 2009. The 2009 Equity Plan replaced the Sun Communities, Inc. Stock Option Plan adopted in 1993, as amended and restated in 1996 and 2000, and terminates automatically July 29, 2019.
	The types of awards that may be granted under the 2009 Equity Plan include stock options, stock appreciation rights, restricted stock, and other stock based awards. The maximum number of shares of common stock that may be issued under the 2009 Equity Plan is 950,000 shares, with 240,820 shares remaining for future issuance.
	During 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 market and performance conditions and the remaining 150,000 shares will vest over time through June 2020. We accounted for the modification of this award is accordance with the FASB ASC Topic 718. See discussion below on the fair value measurement of these awards.
	During 2014, we granted 45,250 shares of restricted stock to employees under our 2009 Equity Plan. The restricted shares had a an average fair value of $52.54 per share and will vest as follows: 35% in 2017; 35% in 2018; 20% in 2019, 5% in 2020; and 5% in 2021. The fair value was determined using the closing price of our common stock on the date the shares were issued.
	During 2014, we also granted 58,000 shares of restricted stock to our executive officers under our 2009 Equity Plan. The restricted shares had a fair value of $48.93 per share and will vest as follows: 20% in 2018; 30% in 2019; 35% in 2020; 10% in 2021; and 5% in 2022. The fair value was determined by using the closing share price of our common stock on the date the shares were issued.
	Director Plan
	The Director Plan was approved by our stockholders at the Annual Meeting of Stockholders held on July 19, 2012. The Director Plan amended and restated in its entirety our 2004 Non-Employee Director Stock Option Plan.
	The types of awards that may be granted under the Director Plan are options, restricted stock and OP units. Only non-employee directors are eligible to participate in the Director Plan. The maximum number of options, restricted stock and OP units that may be issued under the Director Plan is 175,000 shares, with 75,674 shares remaining for future issuance.
	In February 2014, we granted 14,000 shares of restricted stock to our directors under our Director 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 year ended December 31, 2014, 6,833 shares of common stock were issued in connection with the exercise of stock options and the net proceeds received were $0.1 million.
	We have recognized compensation costs associated with share based awards of $4.9 million, $3.2 million, and $1.5 million for the years ended December 31, 2014, 2013, and 2012 respectively.
	11.      Share-Based Compensation, continued
	Restricted Stock
	The majority of our share-based compensation is awarded as service vesting restricted stock grants to executives and key employees. We have also awarded restricted stock to our non-employee directors. We measure the fair value associated with these awards using the closing price of our common stock as of the grant date to calculate compensation cost. Employee awards typically vest over several years and are subject to continued employment by the employee. Award recipients receive distribution payments on unvested shares of restricted stock.
	As of December 31, 2014, we have 50,000 shares of restricted stock issued to Mr. Shiffman subject to certain Company performance criteria, of which 12,500 shares vest on March 1 of each 2015, 2016, 2017 and 2018. Compensation expense is recognized in accordance with ASC Topic 718 and based on an estimate of shares expected to vest. If it is not probable that the performance conditions will be satisfied, we do not recognize compensation expense. The fair value of these awards was measured using the closing price of our common stock as of the grant modification date to calculate compensation cost. Each reporting period, we reevaluate our estimate of the number of shares expected to vest. The performance conditions were satisfied for the shares vesting on March 1, 2015 and compensation expense was recognized as of December 31, 2014.
	We also have 50,000 shares of restricted stock issued to Mr. Shiffman subject to certain market performance criteria, of which 16,667 shares vest on March 1 of each 2016, 2017 and 2018. In accordance with ASC Topic 718, we estimated the fair value of the shares using a Monte Carlo simulation. We recognize compensation cost ratably over each tranche of shares based on the fair value estimated by the model.
	The following table summarizes our restricted stock activity for the years ended December 31, 2014, 2013 and 2012:
		Number of Shares		Weighted Average Grant Date Fair Value
	Unvested restricted shares at January 1, 2012	275,871		$	28.93

	Unvested restricted shares at December 31, 2014	688,743		$	43.87
	Total compensation cost recognized for restricted stock was $4.9 million, $3.2 million, and $1.4 million for the years ended December 31, 2014, 2013, and 2012, respectively. The total fair value of shares vested was $1.4 million, $0.6 million, and $0.2 million for the years ended December 31, 2014, 2013 and 2012, respectively. The remaining net compensation cost related to our
	unvested restricted shares outstanding as of December 31, 2014 is approximately $21.1 million. That expense is expected to be recognized $5.3 million in 2015, $4.7 million in 2016, $4.6 million in 2017 and $6.5 million thereafter.
	Options
	We have granted stock options to certain employees and non-employee directors. Option awards are generally granted with an exercise price equal to the market price of our common stock as of the grant date. Stock options generally vest over a three year
	11.      Share-Based Compensation, continued
	period from the date of grant and have a maximum term of 10 years. No grants of options were made in 2014, 2013 or 2012. We issue new shares of common stock at the time of share option exercise (or share unit conversion).
	The weighted average fair value of the options issued is estimated on the date of the grant using the Binomial (lattice) option pricing model. The options outstanding as of December 31, 2014 consist of 32,500 non-employee director options. There are no employee options outstanding. The compensation expense associated with non-vested stock option awards was not significant for the years ended December 31, 2014, 2013, and 2012.
	The following table summarizes our option activity during the years ended December 31, 2014, 2013 and 2012:

Aggregate intrinsic value represents the value of our closing share price as of the end of the year in excess of the exercise price multiplied by the number of options outstanding or exercisable. The aggregate intrinsic value excludes the effect of stock options that have a zero or negative intrinsic value. For the years ended December 31, 2014, 2013 and 2012, the intrinsic value of exercised options was $0.3 million, $0.2 million and $0.2 million, respectively. For the years ended December 31, 2014, 2013 and 2012, the intrinsic value of vested and exercisable options was $1.0 million, $0.5 million and $0.5 million, respectively.

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 approximately $31.6 million for the year ended December 31, 2014. This transient revenue 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 of 2014.

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 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 certain-specified qualifying sources and at least seventy-five percent (75%) of our gross income must be derived from income qualifying as real estate income under the Code. In addition, a REIT must distribute at least ninety percent (90%) of its REIT ordinary taxable income to its stockholders and meet other tests.
	Qualification as a REIT involves the satisfaction of numerous requirements (some on an annual and quarterly basis) established under highly technical and complex Code provisions for which there are only limited judicial or administrative interpretations, and involves the determination of various factual matters and circumstances not entirely within our control. In addition, frequent changes occur in the area of REIT taxation which requires us to continually monitor our tax status. We analyzed the various REIT tests and determined that we continued to qualify as a REIT for the year ended December 31, 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.
	For income tax purposes, distributions paid to common stockholders consist of ordinary income, capital gains, and return of capital. For the years ended December 31, 2014, 2013, and 2012, distributions paid per share were taxable as follows (unaudited):
		Years Ended December 31,
		2014						2013				2012
		Amount			Percentage			Amount		Percentage		Amount		Percentage
	Ordinary income	$	0.82		31.7	%		$	0.87	34.6	%	$	0.92	48.7	%
	Capital gain	0.64			24.6	%		—		—	%	—		—	%
	Return of capital	1.14			43.7	%		1.65		65.4	%	0.97		51.3	%
	Total distributions declared	$	2.6		100	%		$	2.52	100	%	$	1.89	100	%
	Sun Home Services, Inc. ("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.
	The deferred tax assets included in the consolidated balance sheets are comprised of the following tax effects of temporary differences (in thousands):
		As of December 31,
		2014			2013
	Deferred tax assets:
	Net operating loss carryforwards	$	26,214		$	24,237
	Real estate assets	29,092			23,999
	Amortization of intangibles	(128		)	(128		)
	Gross deferred tax assets	55,178			48,108
	Valuation allowance	(54,178		)	(47,108		)
	Net deferred tax assets	$	1,000		$	1,000
	SHS has operating loss carryforwards of approximately $77.1 million (or $26.2 million after tax) as of December 31, 2014. The loss carryforwards will begin to expire in 2021 through 2031 if not offset by future taxable income. Management believes its net deferred tax asset will be realized but realization is continuously subject to an assessment as to recoverability in the future.
	13.    Income Taxes, continued
	The deferred tax asset will be used when we generate sufficient taxable income. No federal tax expense was recognized in the years ended December 31, 2014, 2013, and 2012.
	We had no unrecognized tax benefits as of December 31, 2014 and 2013. We expect no significant increases or decreases in unrecognized tax benefits due to changes in tax positions within one year of December 31, 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. We recorded a provision for state income taxes of approximately $0.2 million, for each of the years ended December 31, 2014, 2013, and 2012. No deferred tax liability is recorded in relation to the Texas Margin Tax as of December 31, 2014 and 2013.
	We and our subsidiaries are subject to income taxes in the U.S. and various state jurisdictions. Tax regulations within each jurisdiction are subject to the interpretation of the related tax laws and regulations and require significant judgment to apply. With few exceptions, we are no longer subject to U.S. federal, state and local, examinations by tax authorities for the tax years ended December 31, 2008 and prior.
	Our policy is to report income tax penalties and income tax related interest expense as a component of income tax expense.  No interest or penalty associated with any unrecognized income tax benefit or provision was accrued, nor was any income tax related interest or penalty recognized during the years ended December 31, 2014, 2013 and 2012.

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 interest rate derivative contracts that were in effect as of December 31, 2014:
	Type		Purpose		Effective Date	Maturity Date		Notional				Based on		Variable Rate	Fixed Rate		Spread	Effective Fixed Rate
								(in millions)
	Cap		Cap Floating Rate		4/1/12	4/1/15		$	152.4			3 Month LIBOR		0.23%	11.27%		—%	N/A
	Cap		Cap Floating Rate		10/3/11	10/3/16		$	10			3 Month LIBOR		0.23%	11.02%		—%	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 17 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 December 31, 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			December 31, 2014			December 31, 2013						December 31, 2014			December 31, 2013
	Interest rate swap and cap agreements	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 table summarizes the impact of derivative instruments for the years ended December 31, 2014, 2013 and 2012 as recorded in the consolidated statements of operations (in thousands):
	Derivatives in		Amount of gain or (loss)											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 loss 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
	16.    Derivative Instruments and Hedging Activities, continued
	related to hedge ineffectiveness or to amounts excluded from effectiveness testing on our cash flow hedge during the years ended December 31, 2014 and 2013. An insignificant loss was recognized during the year ended December 31, 2012.
	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 December 31, 2014, we had no such deposits recorded.

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 guidance for the 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 swap and 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).
	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 comparable to current prevailing market rates (Level 2).
	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).
	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 comparable to current prevailing market rates (Level 2).
	Other Financial Instruments
	The carrying values of cash and cash equivalents, accounts receivable, and accounts payable approximate their fair market values due to the short-term nature of these instruments.
	17.    Fair Value of Financial Instruments, continued
	The table below sets forth our financial assets and liabilities that required disclosure of their fair values on a recurring basis as of December 31, 2014.  The table presents the carrying values and fair values of our financial instruments as of December 31, 2014 and December 31, 2013 that were measured using the valuation techniques described above (in thousands). The table excludes other financial instruments such as cash and cash equivalents, accounts receivable, and accounts payable because the carrying values associated with these instruments approximate fair value since their maturities are less than one year.

	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 2014-09 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 a 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).

	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.

OFS LLC purchased the loan origination platform of Origen. The purpose of the venture is to originate manufactured housing installment contracts for its members. We accounted for our investment in OFS LLC using the equity method of accounting which we have since suspended. As of December 31, 2014, we had an ownership interest in the OFS LLC of 22.9%, and the carrying value of our investment was zero.
	Loan Origination, Sale and Purchase Agreement. As of 2014, our agreement with OFS LLC, in which OFS LLC agreed to fund loans that meet our underwriting guidelines and then transfer those loans to us pursuant to a Loan Origination, Sale and Purchase Agreement, was terminated. In 2013, we paid OFS LLC a fee of $650 per loan pursuant to a Loan Origination, Sale and Purchase Agreement which totaled approximately $0.1 million and we purchased, at par, $7.7 million of these loans during the year ended December 31, 2013.
	We have entered into the following transactions with Origen:
	Investment in Origen. We own 5,000,000 shares of Origen common stock and Shiffman Origen LLC (which is owned by the Milton M. Shiffman Spouse's Marital Trust, Gary A.

Hermelin, another of our directors, beneficially own approximately 570,000, 10,000, and 200,000 shares of Origen common stock, respectively. We accounted for our investment in Origen using the equity method of accounting which we have since suspended. As of December 31, 2014 we had an ownership interest in Origen of approximately 19%, and the carrying value of our investment was zero.
	Board Membership and Chief Executive Officer. Gary A. Shiffman, our Chairman and Chief Executive Officer, is a board member of Origen, and Ronald A. Klein is a board member and the Chief Executive Officer of Origen.
	In addition to the transactions with Origen described above, Mr. Shiffman, Mr. Weiss and Mr. Klein have entered into the following transactions with us:
	Lease of Executive Offices. Gary A. Shiffman, together with certain of his family members, indirectly owns a 21% equity interest in American Center LLC, the entity from which we lease office space for our principal executive offices. Each of Arthur A. Weiss and Ronald A. Klein owns a less than one percent indirect interest in American Center LLC. Under this lease agreement, we lease approximately 62,900 rentable square feet. The term of the lease is until October 31, 2026, and the base rent through October 31, 2015 is $16.45 per square foot (gross). From November 1, 2015 to October 31, 2016, the base rent will be $16.95 per square foot (gross) and from November 1, 2016 to October 31, 2017, the base rent will be $17.45 per square foot (gross). We also have a temporary lease for approximately 10,500 rentable square feet with base rent equal to $12.71 per square foot (gross). This temporary lease is currently operating on a month to month basis. Our annual rent expense associated with the lease of our executive offices was approximately $1.0 million for each of the years ended December 31, 2014 and 2013, and $0.7 million for the year ended December 31, 2012. Our future annual rent expense will be approximately $1.0 million for 2015, $1.1 million for 2016, 2017 and 2018, $1.2 million for 2019 and $8.8 million thereafter. Each of Mr. Shiffman, Mr. Weiss and Mr. Klein may have a conflict of interest with respect to his obligations as our officer and/or director and his ownership interest in American Center LLC.
	Legal Counsel. During 2012-2014, Jaffe, Raitt, Heuer, & Weiss, Professional Corporation acted as our general counsel and represented us in various matters. Arthur A. Weiss is the Chairman of the Board of Directors and a shareholder of such firm. We incurred legal fees and expenses owed to Jaffe, Raitt, Heuer, & Weiss of approximately $7.5 million, $3.2 million and $3.4 million in the years ended December 31, 2014, 2013 and 2012, respectively.
	Tax Consequences Upon Sale of Properties. Gary A. Shiffman holds limited partnership interests in the Operating Partnership which were received in connection with the contribution of properties from partnerships previously affiliated with him. Prior to any redemption of these limited partnership interests for our common stock, Mr. Shiffman will have tax consequences different from those on us and our public stockholders upon the sale of any of these partnerships. Therefore, we and Mr. Shiffman may have different objectives regarding the appropriate pricing and timing of any sale of those properties.

	Second Closing of Green Courte Acquisition
	During January 2015, we completed the second closing of the acquisition of the Green Courte properties. See Note 2 for details on the acquisition.
	Debt
	In relation to the acquisition of the Green Courte properties (see Note 2), subsequent to year end we refinanced approximately $120.9 million of mortgage debt on 13 of the communities (resulting in proceeds of $126.0 million) at a weighted average interest rate of 3.87% per annum and a weighted average term of 14.1 years, and we assumed approximately $149.9 million of mortgage debt at a weighted average interest rate of 5.74% and a weighted average remaining term of 6.3 years.
	Disposition
	In January 2015, we completed the sale of a MH community comprised of 798 sites located in Indiana for $17.3 million.
	Acquisition Agreement
	On December 4, 2014,we entered into seven separate contribution agreements (the “Contribution Agreements”) with a group of related selling entities (collectively, the “Selling Parties”) with respect to our planned acquisition of a portfolio of seven manufactured housing communities, including associated manufactured homes and certain other personal property and intangibles. After closing, we will operate the properties as six communities rather than seven. The properties are located in the Orlando, Florida area, are comprised of approximately 3,150 manufactured housing sites (approximately 60% of which are in age-restricted communities) and are 96% occupied. In addition to the developed sites, there are approximately 380 potential expansion sites in the Properties.
	Total consideration for the acquisition is approximately $257.6 million, including the assumption of approximately $157.5 million of debt. The balance of the consideration will be paid in a combination of up to approximately $41.8 million in cash, common OP units of the Operating Partnership at an issuance price of $61 per unit and newly-created Series C preferred OP units of the Operating Partnership at an issuance price of $100 per unit (the “Series C Preferred Units”). Of the consideration to be paid with OP units in the Operating Partnership, 60% will be paid in Series C Preferred Units and 40% will be paid in common OP units. Distributions will be paid on the Series C Preferred Units at a rate equal to 4.0% per year from the date of issuance until the second anniversary of the date of issuance, 4.5% per year during the following three years, and 5.0% per year thereafter. Subject to certain limited exceptions, at the holder's option, each Series C Preferred Unit will be exchangeable into 1.1111 shares of the Company's common stock. Holders of Series C Preferred Units will not have voting or consent rights.
	The transaction is subject to the Company's satisfaction with its due diligence investigation and customary closing conditions, including consent of the existing lenders. The transaction is expected to close in the second quarter of 2015.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
Consolidation, Policy [Policy Text Block]	Principles of Consolidation
	The accompanying financial statements include our accounts and all majority-owned and controlled subsidiaries, including entities in which we have a controlling interest or have been determined to be the primary beneficiary of a variable interest entity ("VIE"). All inter-company transactions have been eliminated in consolidation. Any subsidiaries in which we have an ownership percentage equal to or greater than 50%, but less than 100%, or consider a VIE, represent subsidiaries with a noncontrolling interest. The noncontrolling interests in our subsidiaries are allocated their proportionate share of the subsidiaries’ financial results. This allocation is recorded as the noncontrolling interest in our consolidated financial statements.
Use of Estimates, Policy [Policy Text Block]	Use of Estimates
	The preparation of financial statements in conformity with generally accepted accounting principles in the United States (“GAAP”) requires management to make estimates and assumptions related to the reported amounts included in our consolidated financial statements and accompanying footnote disclosures. Actual results could differ from those estimates.
Reclassifications, Policy [Policy Text Block]	Reclassifications and Revisions
	Certain reclassifications have been made to prior periods’ financial statements in order to conform to current period presentation.
	In the fourth quarter of 2014, management identified that certain accruals related to real estate taxes, deferred revenue and utilities primarily associated with communities acquired prior to 2007 were incorrect.  The cumulative reivison for the incorrect accruals approximated $13.5 million.
	Pursuant to the guidance of Staff Accounting Bulletin (“SAB”) No. 99, Materiality, the Company concluded that the errors were not material to any of its prior period financial statements. Although the errors were immaterial to prior periods, the prior period financial statements were revised, in accordance with SAB No. 108, Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements, due to the significance of the out-of-period correction in the fourth quarter of 2014.

Investment property, Policy [Policy Text Block]	Investment Property
	Investment property is recorded at cost, less accumulated depreciation. We review the carrying value of long-lived assets to be held and used for impairment quarterly or whenever events or changes in circumstances indicate a possible impairment.Our primary indicator for potential impairment is based on NOI trends period over period. Circumstances that may prompt a test of recoverability may include a significant decrease in the anticipated market price, an adverse change to the extent or manner in which an asset may be used or in its physical condition or other such events that may significantly change the value of the long-lived asset. An impairment loss is recognized when a long-lived asset’s carrying value is not recoverable and exceeds estimated fair value. We estimate the fair value of our long-lived assets based on discounted future cash flows and any potential disposition proceeds for a given asset. Forecasting cash flows requires management to make estimates and assumptions about such variables as the estimated holding period, rental rates, occupancy and operating expenses during the holding period, as well as disposition proceeds. Management uses its best judgment when developing these estimates and assumptions, but the development of the projected future cash flows is based on subjective variables. Future events could occur which would cause us to conclude that impairment indicators exist, and significant adverse changes in national, regional, or local market conditions or trends may cause us to change the estimates and assumptions used in our impairment analysis. The results of an impairment analysis could be material to our financial statements.
	1	Summary of Significant Accounting Policies, continued
	We periodically receive offers from interested parties to purchase certain of our properties. These offers may be the result of an active program initiated by us to sell the property, or from an unsolicited offer to purchase the property. The typical sale process involves a significant negotiation and due diligence period between us and the potential purchaser. As the intent of this process is to determine if there are items that would cause the purchaser to be unwilling to purchase or we would be unwilling to sell, it is not unusual for such potential offers of sale/purchase to be withdrawn as such issues arise. We classify assets as “held for sale” when it is probable, in our opinion, that a sale transaction will be completed within one year. This typically occurs when all significant contingencies surrounding the closing have been resolved, which often corresponds with the closing date.
	We allocate the purchase price of properties to net tangible and identified intangible assets acquired based on their fair values. In making estimates of fair values for purposes of allocating purchase price, we utilize an independent third party to value the net tangible and identified intangible assets in connection with the acquisition of the respective property. We provide historical and pro forma financial information obtained about each property, as well as any other information needed in order for the third party to ascertain the fair value of the tangible and intangible assets (including in-place leases) acquired.
Other Capitalized Costs, Policy [Policy Text Block]	Other Capitalized Costs
	We capitalize certain costs incurred in connection with the development, redevelopment, capital enhancement and leasing of our properties. Management is required to use professional judgment in determining whether such costs meet the criteria for immediate expense or capitalization. The amounts are dependent on the volume and timing of such activities and the costs associated with such activities. Maintenance, repairs and minor improvements to properties are expensed when incurred. Renovations and improvements to properties are capitalized and depreciated over their estimated useful lives and construction costs related to the development of new community or expansion sites are capitalized until the property is substantially complete. Costs incurred to initially renovate pre-owned and repossessed homes that we acquire for our Rental Program are capitalized and costs incurred to refurbish the homes at turnover and repair the homes while occupied are expensed. Certain expenditures to dealers and residents related to obtaining lessees in our communities are capitalized and amortized over a seven year period based on the anticipated term of occupancy of a resident. Costs associated with implementing our computer systems are capitalized and amortized over the estimated useful lives of the related software and hardware. Costs incurred to obtain new financing are capitalized and amortized over the terms of the related loan agreement using the straight-line method (which approximates the effective interest method).
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and Cash Equivalents
	We consider all highly liquid investments with a maturity of three months or less from the date of purchase to be cash and cash equivalents. The maximum amount of credit risk arising from cash deposits in excess of federally insured amounts was approximately $80.7 million and $5.7 million as of December 31, 2014 and 2013, respectively. From time to time, we may have cash deposits in excess of federally insured amounts.
Inventory, Policy [Text Block]	Inventory
	Inventory of manufactured homes is stated at lower of specific cost or market based on the specific identification method.
Investments in Affiliates, Policy [Policy Text Block]	Investments in Affiliates
	Investments in affiliates in which we do not have a controlling direct or indirect voting interest, but can exercise significant influence over the entity with respect to its operations and major decisions, are accounted for using the equity method of accounting. The carrying value of our investment is adjusted for our proportionate share of the affiliate’s net income or loss and reduced by distributions received. We review the carrying value of our investment in affiliates for other than temporary impairment whenever events or changes in circumstances indicate a possible impairment. Financial condition, operational performance, and other economic trends are some of the factors we consider when we evaluate the existence of impairment indicators. When we have a carrying value of zero for our investment, we suspend the equity method of accounting until such time that the affiliate’s net income equals or exceeds the share of net losses not recognized during the time in which the equity method of accounting was suspended. See Note 7 for additional information.
Notes and Other Receivables, Policy [Policy Text Block]	Notes and Other Receivables
	We provide financing to purchasers of manufactured homes generally located in our communities. The notes are collateralized by the underlying manufactured home sold. Notes receivable include both installment loans retained by the Company as well as transferred loans that have not met the requirements for sale accounting which are presented herein as collateralized receivables (See Note 5 for additional information). For purposes of accounting policy, all notes receivable are considered one homogenous population, as the notes are typically underwritten using the same requirements and terms. Notes receivable are reported at their outstanding unpaid principal balance adjusted for an allowance for loan loss. Interest income is accrued based upon the unpaid principal balance of the loans.
	Past due status of our notes receivable is determined based upon the contractual terms of the note. When a note receivable becomes 60 days delinquent, we stop accruing interest on the note receivable. The interest on nonaccrual loans is accounted for on the cash
	basis until qualifying for return to accrual. Loans are returned to accrual when all principal and interest amounts contractually due are brought current and future payments are reasonably assured. Loans on a nonaccrual status were immaterial at December 31, 2014 and 2013. The ability to collect our notes receivable is measured based on current and historical information and events. We consider numerous factors including: length of delinquency, estimated costs to lease or sell, and repossession history. Our experience supports a high recovery rate for notes receivable; however there is some degree of uncertainty about the recoverability of our investment in these notes receivable. We are generally able to recover our recorded investment in uncollectible notes receivable by repossessing the homes on the notes retained by us and repurchasing the homes on the collateralized receivables, and subsequently selling or leasing these homes to potential residents in our communities. We have established a loan loss reserve based on our estimated unrecoverable costs associated with repossessed/repurchased homes. We estimate our unrecoverable costs to be the repurchase price of the home collateralizing the note receivable plus repair and remarketing costs in excess of the estimated selling price of the home being repossessed. A historical average of this excess cost is calculated based on prior repossessions/repurchases and is applied to our estimated annual future repossessions to create the allowance for both installment and collateralized notes receivable. See Note 5 for additional information.
	We evaluate the collectability of a loan based on our ability to collect the scheduled payments of principal and interest when due according to the contractual terms of the loan agreement. We generally see that if the obligor is delinquent on the loan they are also delinquent on site rent. If the scheduled payment is delinquent more than five to seven days, dependent on state law, we begin the repossession and eviction process simultaneously. This process generally takes 30 to 45 days; due to the short time frame from delinquent loan to repossession we do not evaluate the note receivables for impairment. No loans were considered impaired as of December 31, 2014 and 2013.
	We evaluate the credit quality of our notes receivable at the inception of the receivable. We consider the following factors in order to determine the credit quality of the applicant - rental payment history; home debt to income ratio; total debt to income ratio; length of employment; previous landlord references; and credit scores.
	Other receivables are generally comprised of amounts due from residents for rent and related charges, home sale proceeds receivable from sales near year end and various other miscellaneous receivables. Accounts receivable from residents are typically due within 30 days and stated at amounts due from residents net of an allowance for doubtful accounts. Accounts outstanding longer than the contractual payment terms are considered past due. We evaluate the recoverability of our receivables whenever events occur or there are changes in circumstances such that management believes it is probable that it will be unable to collect all amounts due according to the contractual terms of the loan and lease agreements. Receivables related to community rents are reserved when we believe that collection is less than probable, which is generally after a resident balance reaches 60 to 90 days past due
Restricted Cash, Policy [Policy Text Block]	Restricted cash consists of amounts held in deposit at a financial institution to collateralize derivative instruments in a liability position and deposits for tax, insurance and repair escrows held by lenders in accordance with certain debt agreements. At December 31, 2014 and 2013, $11.8 million and $9.4 million of restricted cash, respectively, was included as a component of Other assets on the consolidated balance sheets.
Identified Intangible Assets, Policy [Policy Text Block]	Identified Intangible Assets
	The Company amortizes identified intangible assets that are determined to have finite lives over the period the assets are expected to contribute directly or indirectly to the future cash flows of the property or business. At December 31, 2014 and 2013, the carrying amounts of the identified intangible assets are included in Other assets on the consolidated balance sheets. See Note 6 for additional information on our intangible assets.
Deferred Tax Assets, Policy [Policy Text Block]	Deferred Tax Assets
	We are subject to certain state taxes that are considered to be income taxes and have certain subsidiaries that are taxed as regular corporations. Deferred tax assets or liabilities are recognized for temporary differences between the tax basis of assets and liabilities and their carrying amounts in the financial statements and net operating loss carryforwards. Deferred tax assets and liabilities are measured using currently enacted tax rates. A valuation allowance is established if, based on the available evidence, it is considered more likely than not that some portion or all of the deferred tax assets will not be realized. See Note 13 for additional information.
Deferred Financing Costs, Policy [Policy Text Block]	Deferred Financing Costs
	Deferred financing costs include fees and costs incurred to obtain long-term financing. The costs are amortized over the terms of the respective loans. Unamortized deferred financing costs are written off when debt is retired before the maturity date. Upon amendment of the line of credit or refinancing of mortgage debt, unamortized deferred financing costs are accounted for in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 470-50-40, Modifications and Extinguishments. At December 31, 2014 and 2013, deferred financing costs are included as a component of Other assets on the consolidated balance sheets.
Share-Based Compensation, Policy [Policy Text Block]	Share-Based Compensation
	Share-based compensation cost for service vesting restricted stock awards is measured based on the closing share price of our common stock on the date of grant. Share-based compensation for restricted stock awards with performance conditions is measured based on an estimate of shares expected to vest. If it is not probable that the performance conditions will be satisfied, we do not recognize compensation expense. We measure the fair value of awards with performance conditions using the closing price of our common stock as of the grant date to calculate compensation cost. Each reporting period, we reevaluate our estimate of the number 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. We recognize compensation cost ratably over each tranche of shares based on the fair value estimated by the model.
	Share-based compensation cost for stock options is estimated at the grant date based on each option’s fair-value as calculated by the Binomial (lattice) option-pricing model. The Binomial (lattice) option-pricing model incorporates various assumptions including expected volatility, expected life, dividend yield, and interest rates. See Note 11 for additional information.
Fair Value of Financial Instruments, Policy [Policy Text Block]	Fair Value of Financial Instruments
	Our financial instruments consist of cash and cash equivalents, accounts and notes receivable, accounts payable, derivative instruments, and debt. We utilize fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures, pursuant to FASB ASC 820, Fair Value Measurements and Disclosures.  See Note 17 for additional information regarding the estimates and assumptions used to estimate the fair value of each class of financial instrument.
Revenue Recognition, Policy [Policy Text Block]	Revenue Recognition
	Rental income attributable to site and home leases is recorded on a straight-line basis when earned from tenants. Leases entered into by tenants are generally for one year terms but may range from month-to-month to two years and are renewable by mutual agreement from us and the resident, or in some cases, as provided by state statute. Revenue from the sale of manufactured homes is recognized upon transfer of title at the closing of the sales transaction. Interest income on notes receivable is recorded on a level yield basis over the life of the notes. We report certain taxes collected from the resident and remitted to taxing authorities in revenue. These taxes include certain Florida property and fire taxes.
Advertising Cost, Policy [Policy Text Block]	Advertising Costs
	Advertising costs are expensed as incurred. As of December 31, 2014, 2013 and 2012, we had advertising costs of $3.2 million, $2.9 million and $2.5 million, respectively.
Depreciation and Amortization, Policy [Policy Text Block]	Depreciation and Amortization
	Depreciation and amortization are computed on a straight-line basis over the estimated useful lives of the assets. Useful lives are 30 years for land improvements and buildings, 10 years for rental homes, seven to 15 years for furniture, fixtures and equipment, and seven to 15 years for intangible assets.
Derivative Instruments and Hedging Activities, Policy [Policy Text Block]	Derivative Instruments and Hedging Activities
	We do not enter into derivative instruments for speculative purposes. We adjust our balance sheet on a quarterly basis to reflect the current fair market value of our derivatives. For those hedges that qualify for cash flow hedge accounting, we adjust our balance sheet on a quarterly basis to reflect current fair market value of our derivatives. Changes in the fair value of derivatives are recorded in earnings or comprehensive income, as appropriate. The ineffective portion of the hedge is immediately recognized in earnings to the extent that the change in value of a derivative does not perfectly offset the change in value of the instrument being hedged. The effective portion of the hedge is recorded in accumulated other comprehensive income. We use standard market conventions to determine the fair values of derivative instruments, including the quoted market prices or quotes from brokers or dealers for the same or similar instruments. All methods of assessing fair value result in a general approximation of value and such value may never actually be realized. See Note 16 for additional information. Cash flows from derivative instruments are classified in the same category as the cash flows of the underlying hedged items, which are in the operating activities section of the consolidated statements of cash flows.

	(2) During the second quarter of 2014, we recorded a gain on disposition of properties, net of $0.9 million. In the fourth quarter of 2014, we identified and recorded a revision to this gain of $3.2 million. Had this revision been recorded in the second quarter instead of the fourth quarter, our basic and diluted earnings per share would have been income of $0.20 in the second quarter and a loss of $0.34 in the fourth quarter. Management of the Company concluded that the effect of the fourth quarter revision was not material to the second and fourth quarter 2014 financial statements.

[1]	(2) During the second quarter of 2014, we recorded a gain on disposition of properties, net of $0.9 million. In the fourth quarter of 2014, we identified and recorded a revision to this gain of $3.2 million. Had this revision been recorded in the second quarter instead of the fourth quarter, our basic and diluted earnings per share would have been income of $0.20 in the second quarter and a loss of $0.34 in the fourth quarter. Management of the Company concluded that the effect of the fourth quarter revision was not material to the second and fourth quarter 2014 financial statements.

In the fourth quarter of 2014, we identified and recorded a revision to this gain of $3.2 million. Had this revision been recorded in the second quarter instead of the fourth quarter, our basic and diluted earnings per share would have been income of $0.20 in the second quarter and a loss of $0.34 in the fourth quarter. Management of the Company concluded that the effect of the fourth quarter revision was not material to the second and fourth quarter 2014 financial statements.
