Footnotes and Definitions                        

(1) Investors in and analysts following the real estate industry utilize funds from operations (FFO), net operating income (NOI), and recurring earnings before interest, tax, depreciation and amortization (Recurring EBITDA) as supplemental performance measures. We believe FFO, NOI, and Recurring EBITDA are appropriate measures given their wide use by and relevance to investors and analysts. FFO, reflecting the assumption that real estate values rise or fall with market conditions, principally adjusts for the effects of GAAP depreciation/amortization of real estate assets. NOI provides a measure of rental operations and does not factor in depreciation/amortization and non-property specific expenses such as general and administrative expenses. Recurring EBITDA, a metric calculated as EBITDA exclusive of certain nonrecurring items, provides a further tool to evaluate ability to incur and service debt and to fund dividends and other cash needs. Additionally, FFO, NOI, and Recurring EBITDA are commonly used in various ratios, pricing multiples/yields and returns and valuation calculations used to measure financial position, performance and value.

FFO is defined by the National Association of Real Estate Investment Trusts (NAREIT) as net income (loss) computed in accordance with generally accepted accounting principles (GAAP), excluding gains (or losses) from sales of depreciable operating property, plus real estate-related depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures. FFO is a non-GAAP financial measure that management believes is a useful supplemental measure of the Company's operating performance. Management generally considers FFO to be a useful measure for reviewing comparative operating and financial performance because, by excluding gains and losses related to sales of previously depreciated operating real estate assets, impairment and excluding real estate asset depreciation and amortization (which can vary among owners of identical assets in similar condition based on historical cost accounting and useful life estimates), FFO provides a performance measure that, when compared period over period, reflects the impact to operations from trends in occupancy rates, rental rates, and operating costs, providing perspective not readily apparent from net income (loss). Management believes that the use of FFO has been beneficial in improving the understanding of operating results of REITs among the investing public and making comparisons of REIT operating results more meaningful. FFO is computed in accordance with the Company's interpretation of standards established by NAREIT, which may not be comparable to FFO reported by other REITs that do not define the term in accordance with the current NAREIT definition or that interpret the current NAREIT definition differently than the Company. The Company also uses FFO excluding certain items, which excludes certain gain and loss items that management considers unrelated to the operational and financial performance of our core business. We believe that this provides investors with another financial measure of our operating performance that is more comparable when evaluating period over period results.

Because FFO excludes significant economic components of net income (loss) including depreciation and amortization, FFO should be used as an adjunct to net income (loss) and not as an alternative to net income (loss). The principal limitation of FFO is that it does not represent cash flow from operations as defined by GAAP and is a supplemental measure of performance that does not replace net income (loss) as a measure of performance or net cash provided by operating activities as a measure of liquidity. In addition, FFO is not intended as a measure of a REIT’s ability to meet debt principal repayments and other cash requirements, nor as a measure of working capital. FFO only provides investors with an additional performance measure that, when combined with measures computed in accordance with GAAP such as net income (loss), cash flow from operating activities, investing activities and financing activities, provide investors with an indication of our ability to service debt and to fund acquisitions and other expenditures. Other REITs may use different methods for calculating FFO, accordingly, our FFO may not be comparable to other REITs.

NOI is derived from revenues minus property operating expenses and real estate taxes. NOI does not represent cash generated from operating activities in accordance with GAAP and should not be considered to be an alternative to net income (loss) (determined in accordance with GAAP) as an indication of the Company's financial performance or to be an alternative to cash flow from operating activities (determined in accordance with GAAP) as a measure of the Company's liquidity; nor is it indicative of funds available for the Company's cash needs, including its ability to make cash distributions. The Company believes that net income (loss) is the most directly comparable GAAP measurement to NOI. Because of the inclusion of items such as interest, depreciation, and amortization, the use of net income (loss) as a performance measure is limited as these items may not accurately reflect the actual change in market value of a property, in the case of depreciation and in the case of interest, may not necessarily be linked to the operating performance of a real estate asset, as it is often incurred at a parent company level and not at a property level. The Company believes that NOI is helpful to investors as a measure of operating performance because it is an indicator of the return on property investment, and provides a method of comparing property performance over time. The Company uses NOI as a key management tool when evaluating performance and growth of particular properties and/or groups of properties. The principal limitation of NOI is that it excludes depreciation, amortization interest expense and non-property specific expenses such as general and administrative expenses, all of which are significant

2nd Quarter 2017 Supplemental Information     22          Sun Communities, Inc.

costs, therefore, NOI is a measure of the operating performance of the properties of the Company rather than of the Company overall.

EBITDA is defined as NOI plus other income, plus (minus) equity earnings (loss) from affiliates, minus general and administrative expenses. EBITDA includes EBITDA from discontinued operations. The Company believes that net income (loss) is the most directly comparable GAAP measurement to EBITDA.

(2) The consideration amounts presented with respect to acquired communities represent the economic transaction and do not contemplate the fair value purchase accounting required by GAAP.

(3) This is a transferred asset transaction which has been classified as collateralized receivables and the cash received from this transaction has been classified as a secured borrowing. The interest income and interest expense accrue at the same rate/amount.

(4) Other income, net for the three months ended June 30, 2017, is comprised of a foreign currency translation gain of $2.2 million partially offset by contingent liability re-measurement of $0.8 million, hurricane related expenses of $0.3 million and other expenses of $0.2 million. For the six months ended June 30, 2017, Other income, net is comprised primarily of a foreign currency translation gain of $3.0 million, partially offset by contingent liability re-measurement of $1.0 million and hurricane related expenses of $0.4 million.

(5) These costs represent the first year expenses incurred to bring acquired properties up to the Company's operating standards, including items such as tree trimming and painting costs that do not meet the Company's capitalization policy.

(6) The effect of certain anti-dilutive convertible securities is excluded from these items.

(7) The renter's monthly payment includes the site rent and an amount attributable to the leasing of the home. The site rent is reflected in Real Property NOI. For purposes of management analysis, the site rent is included in the Rental Program revenue to evaluate the incremental revenue gains associated with implementation of the Rental Program, and to assess the overall growth and performance of the Rental Program and financial impact on our operations.

(8) Lines of credit balance of $0.4 million at June 30, 2017 represents the Company's MH floor plan facility. There were no borrowings outstanding on the revolving loan or term loan as of June 30, 2017. As of June 30, 2017, the effective interest rate on the MH floor plan facility was 7.0 percent, however, the Company pays no interest if the floor plan balance is repaid within 60 days.

(9) Includes manufactured housing (MH) and annual/seasonal recreational vehicle (RV) sites, and excludes transient RV sites and recently completed but vacant expansion sites.

(10) Occupancy reflects current year gains from expansion sites and the conversion of transient RV guests to annual/seasonal RV contracts as vacant in 2016.

(11) Monthly base rent per site pertains to annual/seasonal RV sites and excludes transient RV sites.

(12) Calculated using actual results without rounding.

(13) Includes MH and annual/seasonal RV sites, and excludes transient RV sites.

(14) Includes capital expenditures necessary to maintain asset quality, including purchasing and replacing assets used to operate the community. These capital expenditures include items such as: major road, driveway, and pool improvements; clubhouse renovations; adding or replacing street lights; playground equipment; signage; maintenance facilities; manager housing and property vehicles. The minimum capitalized amount is five hundred dollars.

(15) Includes capital expenditures which improve the asset quality of the community. These costs are incurred when an existing older home moves out, and the site is prepared for a new home, more often than not, a multi-sectional home. These activities which are mandated by strict manufacturer’s installation requirements and state building code include items such as new foundations, driveways, and utility upgrades.

2nd Quarter 2017 Supplemental Information     23          Sun Communities, Inc.

(16) Acquisitions represent the purchase price of existing operating communities and land parcels to develop expansions or new communities. Acquisitions for the six months ended June 30, 2017 also include $29.5 million of capital improvements identified during due diligence that are necessary to bring the community up to the Company’s standards. These include items such as: upgrading clubhouses; landscaping; new street light systems; new mail delivery systems; pool renovation including larger decks, heaters, and furniture; new maintenance facilities; and new signage including main signs and internal road signs. These are considered acquisition costs and although identified during due diligence, they sometimes require 24 to 36 months after closing to complete.

(17) Expansion and development costs consist primarily of construction costs and costs necessary to complete home site improvements.

(18) Capital costs related to revenue generating activities, consist primarily of garages, sheds, and sub-metering of water, sewer and electricity. Revenue generating attractions at our RV resorts are also included here and, occasionally, a special capital project requested by residents and accompanied by an extra rental increase will be classified as revenue producing.

(19) Net leased sites do not include occupied sites acquired in that year.

Certain financial information has been revised to reflect reclassifications in prior periods to conform to current period presentation.
