PART I

ITEM 1. BUSINESS

GENERAL

Sun Communities, Inc., a Maryland corporation, and all wholly-owned or majority-owned and controlled subsidiaries, including Sun Communities Operating Limited Partnership, a Michigan limited partnership (the “Operating Partnership”) and Sun Home Services, Inc. ("SHS") 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 are a fully integrated real estate company which, together with our affiliates and predecessors, have been in the business of acquiring, operating, developing, and expanding manufactured housing ("MH") and recreational vehicle ("RV") communities since 1975. We lease individual parcels of land (“sites”) with utility access for placement of manufactured homes and RVs to our customers. We are also engaged through a taxable subsidiary, SHS, in the marketing, selling, and leasing of new and pre-owned homes to current and future residents in our communities. The operations of SHS support and enhance our occupancy levels, property performance, and cash flows.

We own, operate, or have an interest in a portfolio of MH and RV communities. As of December 31, 2016 , we owned, operated or had an interest in a portfolio of 341 properties in 29 states and Ontario, Canada (collectively, the “Properties”), including 226 MH communities, 87 RV communities, and 28 Properties containing both MH and RV sites. As of December 31, 2016 , the Properties contained an aggregate of 117,376 developed sites comprised of 80,166 developed MH sites, 20,916 annual RV sites (inclusive of both annual and seasonal usage rights), and 16,294 transient RV sites. There are approximately 10,616 additional MH and RV sites suitable for development.

Our executive and principal property management office is located at 27777 Franklin Road, Suite 200, Southfield, Michigan 48034 and our telephone number is (248) 208-2500. We have regional property management offices located in Austin, Texas; Grand Rapids, Michigan; Denver, Colorado; Ft. Myers, Florida; and Orlando, Florida; and we employed an aggregate of 2,679 full and part time employees as of December 31, 2016 .

Our website address is www.suncommunities.com and we make available, free of charge, on or through our website all of our periodic reports, including our Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, and current reports on Form 8-K, as soon as reasonably practicable after we file such reports with the Securities and Exchange Commission (the "SEC").

STRUCTURE OF THE COMPANY

The Operating Partnership is structured as an umbrella partnership REIT, or UPREIT. In 1993, we contributed our net assets to the Operating Partnership in exchange for the sole general partner interest in the Operating Partnership and the majority of all the Operating Partnership’s initial capital. We substantially conduct our operations through the Operating Partnership. The Operating Partnership owns, either directly or indirectly through other subsidiaries, all of our assets. This UPREIT structure enables us to comply with certain complex requirements under the federal tax rules and regulations applicable to REITs, and to acquire MH and RV communities in transactions that defer some or all of the sellers’ tax consequences. The financial results of the Operating Partnership and our other subsidiaries are consolidated in our Consolidated Financial Statements. The financial results include certain activities that do not necessarily qualify as REIT activities under the Internal Revenue Code of 1986, as amended (the “Code”). We have formed taxable REIT subsidiaries, as defined in the Code, to engage in such activities. We use taxable REIT subsidiaries to offer certain services to our residents and engage in activities that would not otherwise be permitted under the REIT rules if provided directly by us or by the Operating Partnership. The taxable REIT subsidiaries include our home sales business, SHS, which provides manufactured home sales, leasing, and other services to current and prospective tenants of the Properties.

Under the partnership agreement, the Operating Partnership is structured to make distributions with respect to certain of the Operating Partnership units ("OP units") at the same time that distributions are made to our common stockholders. The Operating Partnership is structured to permit limited partners holding certain classes or series of OP units to exchange those OP units for shares of our common stock (in a taxable transaction) and achieve liquidity for their investment.

As the sole general partner of the Operating Partnership, we generally have the power to manage and have complete control over the conduct of the Operating Partnership's affairs and all decisions or actions made or taken by us as the general partner pursuant to the partnership agreement are generally binding upon all of the partners and the Operating Partnership.

SUN COMMUNITIES, INC.

We do not own all of the OP units. As of December 31, 2016 , the Operating Partnership had issued and outstanding:

• 75,964,439 common OP units;

• 1,283,819 preferred OP units ("Aspen preferred OP units");

• 367,290 Series A-1 preferred OP units;

• 40,268 Series A-3 preferred OP units;

• 2,315,978 Series A-4 preferred OP units;

• 3,400,000 7.125% Series A Cumulative Redeemable Preferred OP Units (“7.125% Series A OP units”);

• 112,400 Series B-3 preferred OP units; and

• 333,163 Series C preferred OP units.

As of December 31, 2016 , we held:

• 73,205,576 common OP units, or approximately 96% of the issued and outstanding common OP units;

• 1,681,849 Series A-4 preferred OP units, or approximately 73% of the issued and outstanding Series A-4 preferred OP units;

• all of the 7.125% Series A OP units; and

• no Aspen preferred OP units, Series A-1 preferred OP units, Series A-3 preferred OP units, Series B-3 preferred OP units, or Series C preferred OP units.

Ranking and Priority

The various classes and series of OP units issued by the Operating Partnership rank as follows with respect to rights to the payment of distributions and the distribution of assets in the event of any voluntary or involuntary liquidation, dissolution or winding up of the Operating Partnership:

• first, the 7.125% Series A OP units;

• next, the Series A-4 preferred OP units, Aspen preferred OP units and Series A-1 preferred OP units, on parity with each other;

• next, the Series C preferred OP units;

• next, the Series B-3 preferred OP units;

• next, the Series A-3 preferred OP units; and

• finally, the common OP units.

Common OP Units

Subject to certain limitations, the holder of each common OP unit at its option may convert such common OP unit at any time into one share of our common stock. Holders of common OP units are entitled to receive distributions from the Operating Partnership as and when declared by the general partner, provided that all accrued distributions payable on OP units ranking senior to the common OP units have been paid. The holders of common OP units generally receive distributions on the same dates and in amounts equal to the distributions paid to holders of our common stock.

Aspen Preferred OP Units

Subject to certain limitations, at any time prior to January 1, 2024, the holder of each Aspen preferred OP unit at its option may convert such Aspen preferred OP unit into: (a) if the average closing price of our common stock for the preceding ten trading days is $68.00 per share or less, 0.397 common OP units, or (b) if the average closing price of our common stock for the preceding ten trading days is greater than $68.00 per share, the number of common OP units determined by dividing (i) the sum of (A) $27.00 plus (B) 25% of the amount by which the average closing price of our common stock for the preceding ten trading days exceeds $68.00 per share, by (ii) the average closing price of our common stock for the preceding ten trading days. The holders of Aspen preferred OP units are entitled to receive distributions not less than quarterly. Distributions on Aspen preferred OP units are generally paid on the same dates as distributions are paid to holders of common OP units. Each Aspen preferred OP unit is entitled to receive distributions in an amount equal to the product of (x) $27.00, multiplied by (y) an annual rate equal to the 10-year U.S. Treasury bond yield plus 239 basis points; provided, however, that the aggregate distribution rate shall not be less than 6.5% nor more than 9%. On January 2, 2024, we are required to redeem all Aspen preferred OP units that have not been converted to common OP units. In addition, we are required to redeem the Aspen preferred OP units of any holder thereof within five days after receipt of a written demand during the existence of certain uncured Aspen preferred OP unit defaults, including our failure to pay distributions

SUN COMMUNITIES, INC.

on the Aspen preferred OP units when due and our failure to provide certain security for the payment of distributions on the Aspen preferred OP units. We may also redeem Aspen preferred OP units from time to time if we and the holder thereof agree to do so.

Series A-1 Preferred OP Units

Subject to certain limitations, the holder of each Series A-1 preferred OP unit at its option may exchange such Series A-1 preferred OP unit at any time into approximately 2.4390 shares of our common stock (which exchange rate is subject to adjustment upon stock splits, recapitalizations, and similar events). The holders of Series A-1 preferred OP units are entitled to receive distributions not less than quarterly. Distributions on Series A-1 preferred OP units are generally paid on the last day of each quarter. Each Series A-1 preferred OP unit is entitled to receive distributions in an amount equal to the product of $100.00 multiplied by an annual rate equal to 6.0%. Series A-1 preferred OP units do not have any voting or consent rights on any matter requiring the consent or approval of the Operating Partnership's limited partners.

Series A-3 Preferred OP Units

Subject to certain limitations, the holder of each Series A-3 preferred OP unit at its option may exchange such Series A-3 preferred OP unit at any time into approximately 1.8605 shares of our common stock (which exchange rate is subject to adjustment upon stock splits, recapitalizations, and similar events). The holders of Series A-3 preferred OP units are entitled to receive distributions not less than quarterly. Each Series A-3 preferred OP unit is entitled to receive distributions in an amount equal to the product of $100.00 multiplied by an annual rate equal to 4.5%. Series A-3 preferred OP units do not have any voting or consent rights on any matter requiring the consent or approval of the Operating Partnership's limited partners.

Series A-4 Preferred OP Units

In connection with the issuance of our 6.50% Series A-4 Cumulative Convertible Preferred Stock (the "Series A-4 Preferred Stock”) in November 2014, the Operating Partnership created the Series A-4 preferred OP units as a new class of OP units. Series A-4 preferred OP units have economic and other rights and preferences substantially similar to those of the Series A-4 Preferred Stock, including rights to receive distributions at the same time and in the same amounts as distributions paid on Series A-4 Preferred Stock. Each Series A-4 preferred OP unit is exchangeable into approximately 0.4444 shares of common stock or common OP units (which exchange rate is subject to adjustment upon stock splits, recapitalizations, and similar events). The Operating Partnership issued Series A-4 preferred OP units to us in connection with our acquisition of the American Land Lease ("ALL") portfolio of MH communities from Green Courte Real Estate Partners, LLC, Green Courte Real Estate Partners II, LLC, Green Courte Real Estate Partners III, LLC and certain of their affiliated entities (collectively, the "Green Courte parties" or the "Green Courte entities"). In 2014, we issued 669,449 Series A-4 preferred OP units to the sellers as consideration for the ALL acquisition. In January 2015, we issued 200,000 Series A-4 Preferred OP units in a private placement in connection with the ALL acquisition. In June 2015, we issued 34,219 Series A-4 preferred OP units to GCP Fund III Ancillary Holding, LLC. In July 2015, we repurchased 4,066,586 Series A-4 preferred OP units. At December 31, 2016 we held 1,681,849 Series A-4 preferred OP units. The rights of the 1,681,849 Series A-4 preferred OP units held by us mirror the economic rights of the Series A-4 preferred OP units issued to the Green Courte entities, but certain voting, consent, and other rights do not apply to the Series A-4 preferred OP units held by us.

If certain change of control transactions occur or if our common stock ceases to be listed or quoted on an exchange or quotation system, then at any time after November 26, 2019, we or the holders of shares of Series A-4 Preferred Stock and Series A-4 preferred OP units may cause all or any of those shares or units to be redeemed for cash at a redemption price equal to the sum of (i) the greater of (x) the amount that the redeemed shares of Series A-4 Preferred Stock and Series A-4 preferred OP units would have received in such transaction if they had been converted into shares of our common stock immediately prior to such transaction, or (y) $25.00 per share, plus (ii) any accrued and unpaid distributions thereon to, but not including, the redemption date.

7.125% Series A OP Units

In connection with the issuance of our 7.125% Series A Cumulative Redeemable Preferred Stock ("Series A Preferred Stock") in November 2012, the Operating Partnership created the 7.125% Series A OP units as a new class of OP units. All of the outstanding 7.125% Series A OP units are held by us and they have rights, preferences, and other terms substantially similar to the Series A Preferred Stock, including rights to receive distributions at the same time and in the same amounts as distributions paid on Series A Preferred Stock. The Operating Partnership issued the 7.125% Series A OP units to us in consideration of our contributing to the Operating Partnership the net proceeds of our November 2012 offering of shares of Series A Preferred Stock.

SUN COMMUNITIES, INC.

Series B-3 Preferred OP Units

Series B-3 preferred OP units are not convertible. The holders of Series B-3 preferred OP units generally receive distributions on the last day of each quarter. Each Series B-3 preferred OP unit is entitled to receive distributions in an amount equal to the product of $100.00 multiplied by an annual rate equal to 8.0%. As of December 31, 2016, there were outstanding 36,700 Series B-3 preferred OP units which were issued on December 1, 2002, 33,450 Series B-3 preferred OP units which were issued on January 1, 2003, and 42,250 Series B-3 preferred OP units which were issued on January 5, 2004. Subject to certain limitations, (x) during the 90-day period beginning on each of the tenth through fifteenth anniversaries of the issue date of the applicable Series B-3 preferred OP units, (y) at any time after the fifteenth anniversary of the issue date of the applicable Series B-3 preferred OP units, or (z) after our receipt of notice of the death of the electing holder of a Series B-3 preferred OP unit, each holder of Series B-3 preferred OP units may require us to redeem such holder's Series B-3 preferred OP units at the redemption price of $100.00 per unit. In addition, at any time after the fifteenth anniversary of the issue date of the applicable Series B-3 preferred OP units we may redeem, at our option, all of the Series B-3 preferred OP units of any holder thereof at the redemption price of $100.00 per unit. Series B-3 preferred OP units do not have any voting or consent rights on any matter requiring the consent or approval of the Operating Partnership's limited partners.

Series C Preferred OP Units

Subject to certain limitations, the holder of each Series C preferred OP unit at its option may exchange such Series C preferred OP unit at any time into 1.11 shares of our common stock (which exchange rate is subject to adjustment upon stock splits, recapitalizations, and similar events). The holders of Series C preferred OP units are entitled to receive distributions not less than quarterly. Each Series C preferred OP unit is entitled to receive distributions in an amount equal to the product of $100.00 multiplied by an annual rate equal to (i) 4.0% until April 1, 2017, (ii) 4.5% from April 2, 2017 until April 1, 2020, and (iii) 5.0% after April 2, 2020. Series C preferred OP units do not have any voting or consent rights on any matter requiring the consent or approval of the Operating Partnership's limited partners.

REAL PROPERTY OPERATIONS

Properties are designed and improved for several home options of various sizes and designs and consist of both MH communities and RV communities.

A MH community is a residential subdivision designed and improved with sites for the placement of manufactured homes, related improvements, and amenities. Manufactured homes are detached, single‑family homes which are produced off‑site by manufacturers and installed on sites within the community. Manufactured homes are available in a wide array of designs, providing owners with a level of customization generally unavailable in other forms of multi-family housing developments.

Modern manufactured housing communities contain improvements similar to other garden‑style residential developments, including centralized entrances, paved streets, curbs and gutters, and parkways. In addition, these communities also often provide a number of amenities, such as a clubhouse, a swimming pool, shuffleboard courts, tennis courts, and laundry facilities.

A RV community is a resort or park designed and improved with sites for the placement of RVs for varied lengths of time. Properties may also provide vacation rental homes. RV communities include a number of amenities such as restaurants, golf courses, swimming pools, tennis courts, fitness centers, planned activities, and spacious social facilities.

The owner of each home on our Properties leases the site on which the home is located. We own the underlying land, utility connections, streets, lighting, driveways, common area amenities, and other capital improvements and are responsible for enforcement of community guidelines and maintenance. In five of our 341 communities, we do not own the underlying land, but operate the communities pursuant to ground leases. Certain of the Properties provide water and sewer service through public or private utilities, while others provide these services to residents from on‑site facilities. Each owner of a home within our Properties is responsible for the maintenance of the home and leased site. As a result, our capital expenditure needs tend to be less significant relative to multi‑family rental apartment complexes.

SUN COMMUNITIES, INC.

PROPERTY MANAGEMENT

Our property management strategy emphasizes intensive, hands‑on management by dedicated, on‑site district and community managers. We believe that this on‑site focus enables us to continually monitor and address resident concerns, the performance of competitive properties, and local market conditions. As of December 31, 2016 , we employed 2,679 full and part time employees, of which 2,303 were located on‑site as property managers, support staff, or maintenance personnel.

Our community managers are overseen by John B. McLaren, our President and Chief Operating Officer, who has been in the manufactured housing industry since 1995, three Senior Vice Presidents of Operations and Sales, eight Divisional Vice Presidents and 33 Regional Vice Presidents. The Regional Vice Presidents are responsible for semi-annual market surveys of competitive communities, interaction with local manufactured home dealers, regular property inspections, and oversight of property operations and sales functions for seven to 14 properties.

Each district or community manager performs regular inspections in order to continually monitor the Property’s physical condition and to effectively address tenant concerns. In addition to a district or community manager, each district or property has on-site maintenance personnel and management support staff. We hold mandatory training sessions for all new property management personnel to ensure that management policies and procedures are executed effectively and professionally. All of our property management personnel participate in on-going training to ensure that changes to management policies and procedures are implemented consistently. We offer 147 courses for our team members through our Sun University, which has led to increased knowledge and accountability for daily operations and policies and procedures.

HOME SALES AND RENTALS

SHS is engaged in the marketing, selling and leasing of new and pre-owned homes to current and future residents in our communities. Since tenants often purchase a home already on-site within a community, such services enhance occupancy and property performance. Additionally, because many of the homes on the Properties are sold through SHS, better control of home quality in our communities can be maintained than if sales services were conducted solely through third-party brokers. SHS also leases homes to prospective tenants. At December 31, 2016 , SHS had 10,733 occupied leased homes in its portfolio. New and pre-owned homes are purchased for the Rental Program. Leases associated with the Rental Program generally have a term of one year. The Rental Program requires intensive management of costs associated with repair and refurbishment of these homes as the tenants vacate and the homes are re-leased, similar to apartment rentals. We received approximately 46,000 applications during 2016 to live in our Properties, providing a significant "resident boarding" system allowing us to market purchasing a home to the best applicants and to rent to the remainder of approved applicants. Through the Rental Program we are able to demonstrate our product and lifestyle to the renters, while monitoring their payment history and converting qualified renters to owners.

REGULATIONS AND INSURANCE

General

MH and RV community properties are subject to various laws, ordinances and regulations, including regulations relating to recreational facilities such as swimming pools, clubhouses, and other common areas. We believe that each Property has the necessary operating permits and approvals.

Insurance

Our management believes that the Properties are covered by adequate fire, property, business interruption, general liability, and (where appropriate) flood and earthquake insurance provided by reputable companies with commercially reasonable deductibles and limits. We maintain a blanket policy that covers all of our Properties. We have obtained title insurance insuring fee title to the Properties in an aggregate amount which we believe to be adequate. Claims made to our insurance carriers that are determined to be recoverable are classified in other receivables as incurred.

SUN COMMUNITIES, INC.

SITE LEASES OR USAGE RIGHTS

The typical lease we enter into with a tenant for the rental of a manufactured home site is month‑to‑month or year‑to‑year, renewable upon the consent of both parties, or, in some instances, as provided by statute. Certain of our leases, mainly Florida and California properties, are tied to consumer price index or other indices as it relates to rent increases. Generally, market rate adjustments are made on an annual basis. These leases are cancelable for non‑payment of rent, violation of community rules and regulations or other specified defaults. During the five calendar years ended December 31, 2016 , on average 2.3% of the homes in our communities have been removed by their owners and 5.3% of the homes have been sold by their owners to a new owner who then assumes rental obligations as a community resident. The average cost to move a home is approximately $4,000 to $10,000. The average resident remains in our communities for approximately 13 years, while the average home, which gives rise to the rental stream, remains in our communities for over 40 years.

Please see the Risk Factors in Item 1A, and our accompanying Consolidated Financial Statements and related notes thereto beginning on page F-1 of this Annual Report on Form 10-K for more detailed information.

General economic conditions and the concentration of our properties in Florida, Michigan, Texas, and California may affect our ability to generate sufficient revenue.

The market and economic conditions in our current markets generally, and specifically in metropolitan areas of our current markets, may significantly affect manufactured home occupancy or rental rates. Occupancy and rental rates, in turn, may significantly affect our revenues, and if our communities do not generate revenues sufficient to meet our operating expenses, including debt service and capital expenditures, our cash flow and ability to pay or refinance our debt obligations could be adversely affected. We derive significant amounts of our rental income from properties located in Florida, Michigan, Texas, and California. As of December 31, 2016 , 121 properties, representing approximately 35.9% of developed sites, are located in Florida; 67 properties, representing approximately 24.2% of developed sites, are located in Michigan; 21 properties, representing approximately 6.1% of developed sites, are located in Texas; and 22 properties, representing approximately 4.8% of developed sites, are located in California. As a result of the geographic concentration of our Properties in Florida, Michigan, Texas, and California, we are exposed to the risks of downturns in the local economy or other local real estate market conditions which could adversely affect occupancy rates, rental rates, and property values of properties in these markets.

Our income would also be adversely affected if tenants were unable to pay rent or if sites were unable to be rented on favorable terms. If we were unable to promptly relet or renew the leases for a significant number of the sites, or if the rental rates upon such renewal or reletting were significantly lower than expected rates, then our business and results of operations could be adversely affected. In addition, certain expenditures associated with each Property (such as real estate taxes and maintenance costs) generally are not reduced when circumstances cause a reduction in income from the Property. Furthermore, real estate investments are relatively illiquid and, therefore, will tend to limit our ability to vary our portfolio promptly in response to changes in economic or other conditions.

The following factors, among others, may adversely affect the revenues generated by our communities:

• the national and local economic climate which may be adversely impacted by, among other factors, plant closings, and industry slowdowns;

• local real estate market conditions such as the oversupply of MH and RV sites or a reduction in demand for MH and RV sites in an area;

• changes in foreign currency exchange rates, specifically between the U.S. dollar and Canadian dollar;

• the number of repossessed homes in a particular market;

• the lack of an established dealer network;

• the rental market which may limit the extent to which rents may be increased to meet increased expenses without decreasing occupancy rates;

• the perceptions by prospective tenants of the safety, convenience and attractiveness of our Properties and the neighborhoods where they are located;

• zoning or other regulatory restrictions;

• competition from other available MH and RV communities and alternative forms of housing (such as apartment buildings and site‑built single‑family homes);

SUN COMMUNITIES, INC.

• our ability to effectively manage, maintain and insure the Properties;

• increased operating costs, including insurance premiums, real estate taxes, and utilities; and

• the enactment of rent control laws or laws taxing the owners of manufactured homes.

Competition affects occupancy levels and rents which could adversely affect our revenues.

Our Properties are located in developed areas that include other MH and RV community properties. The number of competitive MH and RV community properties in a particular area could have a material adverse effect on our ability to lease sites and increase rents charged at our Properties or at any newly acquired properties. We may be competing with others with greater resources and whose officers and directors have more experience than our officers and directors. In addition, other forms of multi‑family residential properties, such as private and federally funded or assisted multi‑family housing projects and single‑family housing, provide housing alternatives to potential tenants of MH and RV communities.

Our ability to sell or lease manufactured homes may be affected by various factors, which may in turn adversely affect our profitability.

SHS operates in the manufactured home market offering manufactured home sales and leasing services to tenants and prospective tenants of our communities. The market for the sale and lease of manufactured homes may be adversely affected by the following factors:

• downturns in economic conditions which adversely impact the housing market;

• an oversupply of, or a reduced demand for, manufactured homes;

• the difficulty facing potential purchasers in obtaining affordable financing as a result of heightened lending criteria; and

• an increase or decrease in the rate of manufactured home repossessions which provide aggressively priced competition to new manufactured home sales.

Any of the above listed factors could adversely impact our rate of manufactured home sales and leases, which would result in a decrease in profitability.

The cyclical and seasonal nature of the MH and the RV industries may lead to fluctuations in our operating results .

The MH and RV markets can experience cycles of growth and downturn due to seasonality patterns. In the MH market, certain properties maintain higher occupancy during the summer months, while certain other properties maintain higher occupancy during the winter months. The RV market typically shows a decline in demand over the winter months, yet usually produces higher growth in the spring and summer months due to higher use by vacationers. Our results on a quarterly basis can fluctuate due to this cyclicality and seasonality.

We may not be able to integrate or finance our acquisitions and our acquisitions may not perform as expected.

We have acquired and intend to continue to acquire MH and RV properties on a select basis. Our acquisition activities and their success are subject to the following risks:

• we may be unable to acquire a desired property because of competition from other well-capitalized real estate investors, including both publicly traded REITs and institutional investment funds;

• even if we enter into an acquisition agreement for a property, it is usually subject to customary conditions to closing, including completion of due diligence investigations to our satisfaction, which may not be satisfied;

• even if we are able to acquire a desired property, competition from other real estate investors may significantly increase the purchase price;

• we may be unable to finance acquisitions on favorable terms;

SUN COMMUNITIES, INC.

• acquired properties may fail to perform as expected;

• acquired properties may be located in new markets where we face risks associated with a lack of market knowledge or understanding of the local economy, lack of business relationships in the area, and unfamiliarity with local governmental and permitting procedures; and

• we may be unable to quickly and efficiently integrate new acquisitions, particularly acquisitions of portfolios of properties, into our existing operations.

If any of the above risks occurred, our business and results of operations could be adversely affected.

In addition, we may acquire properties subject to liabilities and without any recourse, or with only limited recourse, with respect to unknown liabilities. As a result, if a liability were to be asserted against us based upon ownership of those properties, we might have to pay substantial sums to settle it, which could adversely affect our cash flow.

Increases in taxes and regulatory compliance costs may reduce our results of operations.

Costs resulting from changes in real estate laws, income taxes, service or other taxes, generally are not passed through to tenants under leases and may adversely affect our results of operations and financial condition. Similarly, changes in laws increasing the potential liability for environmental conditions existing on properties or increasing the restrictions on discharges or other conditions may result in significant unanticipated expenditures, which would adversely affect our business and results of operations.

We may not be able to integrate or finance our expansion and development activities.

From time to time, we engage in the construction and development of new communities or expansion of existing communities, and may continue to engage in the development and construction business in the future. Our construction and development pipeline may be exposed to the following risks which are in addition to those risks associated with the ownership and operation of established MH and RV communities:

• we may not be able to obtain financing with favorable terms for community development which may make us unable to proceed with the development;

• we may be unable to obtain, or face delays in obtaining, necessary zoning, building and other governmental permits and authorizations, which could result in increased costs and delays, and even require us to abandon development of the community entirely if we are unable to obtain such permits or authorizations;

• we may abandon development opportunities that we have already begun to explore and as a result we may not recover expenses already incurred in connection with exploring such development opportunities;

• we may be unable to complete construction and lease‑up of a community on schedule resulting in increased debt service expense and construction costs;

• we may incur construction and development costs for a community which exceed our original estimates due to increased materials, labor or other costs, which could make completion of the community uneconomical and we may not be able to increase rents to compensate for the increase in development costs which may impact our profitability;

• we may be unable to secure long‑term financing on completion of development resulting in increased debt service and lower profitability; and

• occupancy rates and rents at a newly developed community may fluctuate depending on several factors, including market and economic conditions, which may result in the community not being profitable.

If any of the above risks occurred, our business and results of operations could be adversely affected.

Rent control legislation may harm our ability to increase rents.

State and local rent control laws in certain jurisdictions may limit our ability to increase rents and to recover increases in operating expenses and the costs of capital improvements. Enactment of such laws has been considered from time to time in other jurisdictions.

SUN COMMUNITIES, INC.

Certain Properties are located, and we may purchase additional properties, in markets that are either subject to rent control or in which rent-limiting legislation exists or may be enacted.

We may be subject to environmental liability.

Under various federal, state and local laws, ordinances and regulations, an owner or operator of real estate is liable for the costs of removal or remediation of certain hazardous substances at, on, under or in such property. Such laws often impose such liability without regard to whether the owner knew of, or was responsible for, the presence of such hazardous substances. The presence of such substances, or the failure to properly remediate such substances, may adversely affect the owner’s ability to sell or rent such property, to borrow using such property as collateral or to develop such property. Persons who arrange for the disposal or treatment of hazardous substances also may be liable for the costs of removal or remediation of such substances at a disposal or treatment facility owned or operated by another person. In addition, certain environmental laws impose liability for the management and disposal of asbestos‑containing materials and for the release of such materials into the air. These laws may provide for third parties to seek recovery from owners or operators of real properties for personal injury associated with asbestos‑containing materials. In connection with the ownership, operation, management, and development of real properties, we may be considered an owner or operator of such properties and, therefore, are potentially liable for removal or remediation costs, and also may be liable for governmental fines and injuries to persons and property. When we arrange for the treatment or disposal of hazardous substances at landfills or other facilities owned by other persons, we may be liable for the removal or remediation costs at such facilities.

All of the Properties have been subject to a Phase I or similar environmental audit (which involves general inspections without soil sampling or ground water analysis) completed by independent environmental consultants. These environmental audits have not revealed any significant environmental liability that would have a material adverse effect on our business. These audits cannot reflect conditions arising after the studies were completed, and no assurances can be given that existing environmental studies reveal all environmental liabilities, that any prior owner or operator of a property or neighboring owner or operator did not create any material environmental condition not known to us, or that a material environmental condition does not otherwise exist as to any one or more Properties.

Losses in excess of our insurance coverage or uninsured losses could adversely affect our cash flow.

We maintain comprehensive liability, fire, property, business interruption, general liability, and (where appropriate) flood and earthquake insurance, provided by reputable companies with commercially reasonable deductibles and limits. Certain types of losses including, but not limited to, riots or acts of war, may be either uninsurable or not economically insurable. In the event an uninsured loss occurs, we could lose both our investment in and anticipated profits and cash flow from the affected property. Any loss could adversely affect our ability to repay our debt.

FINANCING AND INVESTMENT RISKS

Our significant amount of debt could limit our operational flexibility or otherwise adversely affect our financial condition .

We have a significant amount of debt. As of December 31, 2016 , we had approximately $3.1 billion of total debt outstanding, consisting of approximately $2.8 billion in debt that is collateralized by mortgage liens on 189 of the Properties, $144.5 million that is secured by collateralized receivables, $100.1 million on our lines of credit, and $45.9 million that is unsecured debt. If we fail to meet our obligations under our secured debt, the lenders would be entitled to foreclose on all or some of the collateral securing such debt which could have a material adverse effect on us and our ability to make expected distributions, and could threaten our continued viability.

We are subject to the risks normally associated with debt financing, including the following risks:

• our cash flow may be insufficient to meet required payments of principal and interest, or require us to dedicate a substantial portion of our cash flow to pay our debt and the interest associated with our debt rather than to other areas of our business;

• our existing indebtedness may limit our operating flexibility due to financial and other restrictive covenants, including restrictions on incurring additional debt;

• it may be more difficult for us to obtain additional financing in the future for our operations, working capital requirements, capital expenditures, debt service or other general requirements;

• we may be more vulnerable in the event of adverse economic and industry conditions or a downturn in our business;

SUN COMMUNITIES, INC.

• we may be placed at a competitive disadvantage compared to our competitors that have less debt; and

• we may not be able to refinance at all or on favorable terms, as our debt matures.

If any of the above risks occurred, our financial condition and results of operations could be materially adversely affected.

We may incur substantially more debt, which would increase the risks associated with our substantial leverage.

Despite our current indebtedness levels, we may incur substantially more debt in the future. If new debt is added to our current debt levels, an even greater portion of our cash flow will be needed to satisfy our debt service obligations. As a result, the related risks that we now face could intensify and increase the risk of a default on our indebtedness.

TAX RISKS

We may suffer adverse tax consequences and be unable to attract capital if we fail to qualify as a REIT.

We believe that since our taxable year ended December 31, 1994, we have been organized and operated, and intend to continue to operate, so as to qualify for taxation as a REIT under the Code. Although we believe that we have been and will continue to be organized and have operated and will continue to operate so as to qualify for taxation as a REIT, we cannot be assured that we have been or will continue to be organized or operated in a manner to so qualify or remain so qualified. 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 require us to continually monitor our tax status.

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). Moreover, unless entitled to relief under certain statutory provisions, we also would be disqualified from treatment as a REIT for the four taxable years following the year during which qualification was lost. This treatment would reduce our net earnings available for investment or distribution to stockholders because of the additional tax liability to us for the years involved. In addition, distributions to stockholders would no longer be required to be made.

Federal, state and foreign income tax laws governing REITs and related interpretations may change at any time, and any such legislative or other actions affecting REITs could have a negative effect on us.

Federal, state and foreign income tax laws governing REITs or the administrative interpretations of those laws may be amended at any time. Federal, state, and foreign tax laws are under constant review by persons involved in the legislative process, at the Internal Revenue Service and the U.S. Department of the Treasury, and at various state and foreign tax authorities. Changes to tax laws, regulations, or administrative interpretations, which may be applied retroactively, could adversely affect us. We cannot predict whether, when, in what forms, or with what effective dates, the tax laws, regulations, and administrative interpretations applicable to us may be changed. Accordingly, we cannot assert that any such change will not significantly affect either our ability to qualify for taxation as a REIT or the income tax consequences to us.

We intend for the Operating Partnership to be taxed as a partnership, but we cannot guarantee that it will qualify.

We believe that the Operating Partnership has been organized as a partnership and will qualify for treatment as such under the Code. However, if the Operating Partnership is deemed to be a “publicly traded partnership,” it will be treated as a corporation instead of a partnership for federal income tax purposes unless at least 90% of its income is qualifying income as defined in the Code. The income requirements applicable to REITs and the definition of “qualifying income” for purposes of this 90% test are similar in most respects. Qualifying income for the 90% test generally includes passive income, such as specified types of real property rents, dividends, and interest. We believe that the Operating Partnership has and will continue to meet this 90% test, but we cannot guarantee that it has or will. If the Operating Partnership were to be taxed as a regular corporation, it would incur substantial tax liabilities, we would fail to qualify as a REIT for federal income tax purposes, and our ability to raise additional capital could be significantly impaired.

SUN COMMUNITIES, INC.

Our ability to accumulate cash may be restricted due to certain REIT distribution requirements.

In order to qualify as a REIT, we must distribute to our stockholders at least 90% of our REIT taxable income (calculated without any deduction for dividends paid and excluding net capital gain) and to avoid federal income taxation, our distributions must not be less than 100% of our REIT taxable income, including capital gains. As a result of the distribution requirements, we do not expect to accumulate significant amounts of cash. Accordingly, these distributions could significantly reduce the cash available to us in subsequent periods to fund our operations and future growth.

Our taxable REIT subsidiaries, or TRSs, are subject to special rules that may result in increased taxes.

As a REIT, we must pay a 100% penalty tax on certain payments that we receive if the economic arrangements between us and any of our TRSs are not comparable to similar arrangements between unrelated parties. The Internal Revenue Service may successfully assert that the economic arrangements of any of our inter-company transactions are not comparable to similar arrangements between unrelated parties.

Dividends payable by REITs do not qualify for the reduced tax rates applicable to certain dividends.

The maximum federal tax rate for certain qualified dividends payable to domestic stockholders that are individuals, trusts and estates is 20%. Dividends payable by REITs, however, are generally not eligible for this reduced rate. Although this rule does not adversely affect the taxation of REITs or dividends paid by REITs, the more favorable rates applicable to regular qualified corporate dividends could cause investors who are individuals, trusts and estates to perceive investments in REITs to be relatively less competitive than investments in stock of non-REIT corporations that pay dividends, which could adversely affect the comparative value of the stock of REITs, including our common stock and preferred stock.

Complying with REIT requirements may cause us to forego otherwise attractive opportunities.

To remain qualified as a REIT for federal income tax purposes, we must continually satisfy requirements and tests under the tax law concerning, among other things, the sources of our income, the nature and diversification of our assets, the amounts we distribute to our stockholders and the ownership of our stock. In order to meet these tests, we may be required to forego or limit attractive business or investment opportunities and distribute all of our net earnings rather than invest in attractive opportunities or hold larger liquid reserves. Therefore, compliance with the REIT requirements may hinder our ability to operate solely to maximize profits.

Our ability to use net operating loss carryforwards to reduce future tax payments may be limited if we experience a change in ownership, or if taxable income does not reach sufficient levels.

Under Section 382 of the Code, if a corporation undergoes an “ownership change” (generally defined as a greater than 50% change (by value) in its equity ownership over a rolling three-year period), the corporation’s ability to use its pre-ownership-change net operating loss carryforwards to offset its post-ownership-change income may be limited. We may experience ownership changes in the future. If an ownership change were to occur, we would be limited in the portion of net operating loss carryforwards that we could use in the future to offset taxable income for U.S. federal income tax purposes.

BUSINESS RISKS

Some of our directors and officers may have conflicts of interest with respect to certain related party transactions and other business interests.

Lease of Executive Offices. Gary A. Shiffman, together with certain of his family members, indirectly owns a 16.75% equity interest in American Center LLC, the entity from which we lease office space for our principal executive offices. Each of Brian M. Hermelin, Ronald A. Klein and Arthur A. Weiss indirectly owns a less than one percent interest in American Center LLC. Mr. Shiffman is our Chief Executive Officer and Chairman of the Board. Each of Mr. Hermelin, Mr. Klein and Mr. Weiss is a director of the Company. Under this agreement, we lease approximately 71,513 rentable square feet of permanent space, and 9,140 rentable square feet of temporary space. The initial term of the lease is until October 31, 2026, and the base rent is $17.45 per square foot (gross) until October 31, 2017, for both permanent and temporary space, with graduated rental increases thereafter. Each of Mr. Shiffman, Mr. Hermelin, Mr. Klein and Mr. Weiss 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.

SUN COMMUNITIES, INC.

Legal Counsel. During 2016 , Jaffe, Raitt, Heuer, & Weiss, Professional Corporation acted as our general counsel and represented us in various matters. Arthur A. Weiss, one of our directors, 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 $8.0 million , $4.6 million and $7.5 million in the years ended December 31, 2016 , 2015 and 2014 , 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.

We rely on key management .

We are dependent on the efforts of our executive officers, Gary A. Shiffman, John B. McLaren, Karen J. Dearing, and Jonathan M. Colman. The loss of services of one or more of these executive officers could have a temporary adverse effect on our operations. We do not currently maintain or contemplate obtaining any “key-man” life insurance on the Executive Officers.

Certain provisions in our governing documents may make it difficult for a third-party to acquire us.

9.8% Ownership Limit. In order to qualify and maintain our qualification as a REIT, not more than 50% of the outstanding shares of our capital stock may be owned, directly or indirectly, by five or fewer individuals. Thus, ownership of more than 9.8%, in number of shares or value, of the issued and outstanding shares of our capital stock by any single stockholder has been restricted, with certain exceptions, for the purpose of maintaining our qualification as a REIT under the Code. Such restrictions in our charter do not apply to Milton M. Shiffman, Gary A. Shiffman, and Robert B. Bayer; trustees, personal representatives and agents to the extent acting for them or their respective estates; or certain of their respective relatives.

The 9.8% ownership limit, as well as our ability to issue additional shares of common stock or shares of other stock (which may have rights and preferences over the common stock), may discourage a change of control of the Company and may also: (1) deter tender offers for the common stock, which offers may be advantageous to stockholders; and (2) limit the opportunity for stockholders to receive a premium for their common stock that might otherwise exist if an investor were attempting to assemble a block of common stock in excess of 9.8% of our outstanding shares or otherwise effect a change of control of the Company.

Preferred Stock. Our charter authorizes the Board of Directors to issue up to 20,000,000 shares of preferred stock and to establish the preferences and rights (including the right to vote and the right to convert into shares of common stock) of any shares issued.

Our charter designates 3,450,000 shares of preferred stock as 7.125% Series A Cumulative Redeemable Preferred Stock, $0.01 par value per share, and issued 3,400,000 of such shares of stock. Our charter designates 6,364,770 shares of preferred stock as 6.50% Series A-4 Cumulative Convertible Preferred Stock, $0.01 par value per share of which 1,681,849 shares were issued and outstanding as of December 31, 2016. The power to issue preferred stock could have the effect of delaying or preventing a change in control of the Company even if a change in control were in the stockholders' interest.

Upon the occurrence of certain change of control events, the result of which is that shares of our common stock and the common securities of the acquiring or surviving entity (or ADRs representing such securities) are not listed on the New York Stock Exchange (“NYSE”), the NYSE MKT or NASDAQ or listed or quoted on an exchange or quotation system that is a successor to the NYSE, the NYSE MKT or NASDAQ, holders of shares of Series A Preferred Stock will have the right, subject to certain limitations, to convert some or all of their shares of Series A Preferred Stock into shares of our common stock (or equivalent value of alternative consideration) and under these circumstances we will also have a special optional redemption right to redeem the shares of Series A Preferred Stock. Upon such a conversion, the holders of shares of Series A Preferred Stock will be limited to a maximum number of shares of our common stock. If our common stock price, as determined in accordance with our charter for these purposes, is less than $20.97, subject to adjustment, the holders will receive a maximum of 1.1925 shares of our common stock per shares of Series A Preferred Stock, which may result in a holder receiving value that is less than the liquidation preference of the Series A Preferred Stock.

Subject to certain limitations, upon written notice to us, each holder of shares of Series A-4 Preferred Stock at its option may convert each share of Series A-4 Preferred Stock held by it for that number of shares of our common stock equal to the quotient obtained by dividing $25.00 by the then-applicable conversion price. The initial conversion price is $56.25, so initially each share of Series A-4 Preferred Stock is convertible into approximately 0.4444 shares of common stock. The conversion price is subject to adjustment upon various events. At our option, instead of issuing the shares of common stock to the converting holder of Series

SUN COMMUNITIES, INC.

A-4 Preferred Stock as described above, we may make a cash payment to the converting holder with respect to each share of Series A-4 Preferred Stock the holder desires to convert equal to the fair market value of one share of our common stock. If, at any time after November 26, 2019, the volume weighted average of the daily volume weighted average price of a share of our common stock on the NYSE equals or exceeds 115.5% of the then prevailing conversion price for at least 20 trading days in a period of 30 consecutive trading days, then, within 10 days thereafter, upon written notice to the holders thereof, we may convert each outstanding share of Series A-4 Preferred Stock into that number of shares of common stock equal to the quotient obtained by dividing $25.00 by the then prevailing conversion price.

These features of the Series A Preferred Stock and Series A-4 Preferred Stock may have the effect of inhibiting a third-party from making an acquisition proposal for the Company or of delaying, deferring or preventing a change of control of the Company under circumstances that otherwise could provide the holders of our common stock and preferred stock with the opportunity to realize a premium over the then-current market price or that stockholders may otherwise believe is in their best interests.

Rights Plan. We adopted a stockholders' rights plan in 2008 that provides our stockholders (other than a stockholder attempting to acquire a 15% or greater interest in us) with the right to purchase our stock at a discount in the event any person attempts to acquire a 15% or greater interest in us. Because this plan could make it more expensive for a person to acquire a controlling interest in us, it could have the effect of delaying or preventing a change in control even if a change in control were in the stockholders' interest.

Certain provisions of Maryland law could inhibit changes in control, which may discourage third parties from conducting a tender offer or seeking other change of control transactions that could involve a premium price for our common stock or that our stockholders otherwise believe to be in their best interest.

Certain provisions of the Maryland General Corporation Law, ("MGCL"), may have the effect of inhibiting a third-party from making a proposal to acquire us or of impeding a change of control under circumstances that otherwise could provide the holders of shares of our capital stock with the opportunity to realize a premium over the then-prevailing market price of such shares, including:

• “business combination” provisions that, subject to limitations, prohibit certain business combinations between us and an “interested stockholder” (defined generally as any person who beneficially owns 10% or more of the voting power of our shares or an affiliate thereof or an affiliate or associate of ours who was the beneficial owner, directly or indirectly, of 10% or more of the voting power of our then outstanding voting stock at any time within the two-year period immediately prior to the date in question) for five years after the most recent date on which the stockholder becomes an interested stockholder, and thereafter impose fair price and/or supermajority and stockholder voting requirements on these combinations; and

• “control share” provisions that provide that “control shares” of our company (defined as shares that, when aggregated with other shares controlled by the stockholder, entitle the stockholder to exercise one of three increasing ranges of voting power in electing directors) acquired in a “control share acquisition” (defined as the direct or indirect acquisition of ownership or control of issued and outstanding “control shares”) have no voting rights except to the extent approved by our stockholders by the affirmative vote of at least two-thirds of all the votes entitled to be cast on the matter, excluding all interested shares.

The provisions of the MGCL relating to business combinations do not apply, however, to business combinations that are approved or exempted by our Board of Directors prior to the time that the interested stockholder becomes an interested stockholder. As permitted by the statute, our Board of Directors has by resolution exempted Milton M. Shiffman, Robert B. Bayer, and Gary A. Shiffman, their affiliates and all persons acting in concert or as a group with the foregoing, from the business combination provisions of the MGCL and, consequently, the five-year prohibition and the supermajority vote requirements will not apply to business combinations between us and these persons. As a result, these persons may be able to enter into business combinations with us that may not be in the best interests of our stockholders without compliance by our Company with the supermajority vote requirements and the other provisions of the statute.

Also, pursuant to a provision in our bylaws, we have exempted any acquisition of our stock from the control share provisions of the MGCL. However, our Board of Directors may by amendment to our bylaws opt in to the control share provisions of the MGCL at any time in the future.

Additionally, Subtitle 8 of Title 3 of the MGCL permits our Board of Directors, without stockholder approval and regardless of what is currently provided in our charter or bylaws, to elect to be subject to certain provisions relating to corporate governance

SUN COMMUNITIES, INC.

that may have the effect of delaying, deferring or preventing a transaction or a change of control of our company that might involve a premium to the market price of our common stock or otherwise be in our stockholders' best interests. These provisions include a classified board; two-thirds vote to remove a director; that the number of directors may only be fixed by the Board of Directors; that vacancies on the board as a result of an increase in the size of the board or due to death, resignation or removal can only be filled by the board, and the director appointed to fill the vacancy serves for the remainder of the full term of the class of director in which the vacancy occurred; and a majority requirement for the calling by stockholders of special meetings. Other than a classified board, the filling of vacancies as a result of the removal of a director and a majority requirement for the calling by stockholders of special meetings, we are already subject to these provisions, either by provisions of our charter and bylaws unrelated to Subtitle 8 or by reason of an election to be subject to certain provisions of Subtitle 8. In the future, our Board of Directors may elect, without stockholder approval, to make us subject to the provisions of Subtitle 8 to which we are not currently subject.

Changes in our investment and financing policies may be made without stockholder approval.

Our investment and financing policies, and our policies with respect to certain other activities, including our growth, debt, capitalization, distributions, REIT status, and operating policies, are determined by our Board of Directors. Although the Board of Directors has no present intention to do so, these policies may be amended or revised from time to time at the discretion of the Board of Directors without notice to or a vote of our stockholders. Accordingly, stockholders may not have control over changes in our policies and changes in our policies may not fully serve the interests of all stockholders.

Substantial sales of our common stock could cause our stock price to fall .

The sale or issuance of substantial amounts of our common stock or preferred stock, whether directly by us or in the secondary market, the perception that such sales could occur or the availability of future issuances of shares of our common stock, preferred stock, OP units or other securities convertible into or exchangeable or exercisable for our common stock or preferred stock, could materially and adversely affect the market price of our common stock or preferred stock and our ability to raise capital through future offerings of equity or equity-related securities. In addition, we may issue capital stock that is senior to our common stock in the future for a number of reasons, including to finance our operations and business strategy, to adjust our ratio of debt to equity or for other reasons.

Based on the applicable conversion ratios then in effect, as of February 16, 2017, in the future we may issue to the limited partners of the Operating Partnership, up to approximately 2.8 million shares of our common stock in exchange for their OP units. The limited partners may sell such shares pursuant to registration rights, if available, or an available exemption from registration. As of February 16, 2017, options to purchase 3,000 shares of our common stock were outstanding under our equity incentive plans. We currently have the authority to issue restricted stock awards or options to purchase up to an additional 1,570,934 shares of our common stock pursuant to our equity incentive plans. In addition, we entered into an At-the-Market Offering Sales Agreement in June 2015 to issue and sell shares of common stock. As of February 16, 2017, our Board of Directors had authorized us to sell approximately an additional $144.5 million of common stock under this agreement. No prediction can be made regarding the effect that future sales of shares of our common stock or our other securities will have on the market price of shares.

An increase in interest rates may have an adverse effect on the price of our common stock.

One of the factors that may influence the price of our common stock in the public market will be the annual distributions to stockholders relative to the prevailing market price of the common stock. An increase in market interest rates may tend to make the common stock less attractive relative to other investments, which could adversely affect the market price of our common stock.

We may be adversely impacted by fluctuations in foreign currency exchange rates.

Our investments in and operations of Canadian properties are exposed to the effects of changes in the Canadian dollar against the U.S. dollar. Changes in foreign currency exchange rates cannot always be predicted; as a result, substantial unfavorable changes in exchange rates could have a material adverse effect on our financial condition and results of operations.

The volatility in economic conditions and the financial markets may adversely affect our industry, business and financial performance.

The U.S. interest rate environment, oil price fluctuations, a new U.S. President, uncertain tax and economic plans in Congress, and turmoil in emerging markets have created uncertainty and volatility in the U.S. and global economies. Continued economic uncertainty, both nationally and internationally, causes increased volatility in investor confidence thereby creating similar volatility in the availability of both debt and equity capital in the financial markets. The other risk factors presented in this Annual Report

SUN COMMUNITIES, INC.

on Form 10-K discuss some of the principal risks inherent in our business, including liquidity risks, operational risks, and credit risks, among others. Turbulence in financial markets accentuates each of these risks and magnifies their potential effect on us. If such volatility is experienced in future periods, there could be an adverse impact on our access to capital, stock price and our operating results.

Our business operations may not generate the cash needed to make distributions on our capital stock or to service our indebtedness, and we may adjust our common stock distribution policy.

Our ability to make distributions on our common stock and preferred stock, and payments on our indebtedness and to fund planned capital expenditures will depend on our ability to generate cash in the future. We cannot assure you that our business will generate sufficient cash flow from operations or that future borrowings will be available to us in an amount sufficient to enable us to make distributions on our common stock or preferred stock, to pay our indebtedness or to fund our other liquidity needs.

The decision to declare and pay distributions on shares of our common stock in the future, as well as the timing, amount and composition of any such future distributions, will be at the sole discretion of our Board of Directors in light of conditions then existing, including our earnings, financial condition, capital requirements, debt maturities, the availability of debt and equity capital, applicable REIT and legal restrictions and the general overall economic conditions and other factors. Any change in our distribution policy could have a material adverse effect on the market price of our common stock.

Our ability to pay distributions is limited by the requirements of Maryland law.

Our ability to pay distributions on our common stock and preferred stock is limited by the laws of Maryland. Under Maryland law, a Maryland corporation generally may not make a distribution if, after giving effect to the distribution, the corporation would not be able to pay its debts as they become due in the usual course of business, or the corporation's total assets would be less than the sum of its total liabilities plus, unless the corporation's charter provides otherwise, the amount that would be needed, if the corporation were dissolved at the time of the distribution, to satisfy the preferential rights upon dissolution of stockholders whose preferential rights are superior to those receiving the distribution, provided, however, that a Maryland corporation may make a distribution from: (i) its net earnings for the fiscal year in which the distribution is made; (ii) its net earnings for the preceding fiscal year; or (iii) the sum of its net earnings for its preceding eight fiscal quarters even if, after such distribution, the corporation's total assets would be less than its total liabilities. Accordingly, we generally may not make a distribution on our common stock or preferred stock if, after giving effect to the distribution, we would not be able to pay our debts as they become due in the usual course of business or, unless paid from one of the permitted sources of net earnings as described above, our total assets would be less than the sum of our total liabilities plus, unless the terms of such class or series of stock provide otherwise, the amount that would be needed to satisfy the preferential rights upon dissolution of the holders of shares of any class or series of stock then outstanding, if any, with preferential rights upon dissolution senior to those of our common stock or currently outstanding preferred stock.

We may not be able to pay distributions upon events of default under our financing documents.

Some of our financing documents contain restrictions on distributions upon the occurrence of events of default thereunder. If such an event of default occurs, such as our failure to pay principal at maturity or interest when due for a specified period of time, we would be prohibited from making payments on our common stock and preferred stock.

Our share price could be volatile and could decline, resulting in a substantial or complete loss on our stockholders' investment.

The stock markets, including the NYSE on which we list our common stock and Series A Preferred Stock, have experienced significant price and volume fluctuations. As a result, the market price of our common stock and preferred stock could be similarly volatile, and investors in our common stock and preferred stock may experience a decrease in the value of their shares, including decreases unrelated to our operating performance or prospects. The price of our common stock and preferred stock could be subject to wide fluctuations in response to a number of factors, including:

• issuances of other equity securities in the future, including new series or classes of preferred stock;

• our operating performance and the performance of other similar companies;

• our ability to maintain compliance with covenants contained in our debt facilities;

SUN COMMUNITIES, INC.

• actual or anticipated variations in our operating results, funds from operations, cash flows or liquidity;

• changes in expectations of future financial performance or changes in our earnings estimates or those of analysts;

• changes in our distribution policy;

• publication of research reports about us or the real estate industry generally;

• increases in market interest rates that lead purchasers of our common stock to demand a higher dividend yield;

• changes in foreign currency exchange rates, specifically between the U.S. dollar and Canadian dollar;

• changes in market valuations of similar companies;

• increases in market interest rates that lend purchases of our common stock and preferred stock to demand a higher dividend yield;

• adverse market reaction to the amount of our debt outstanding at any time, the amount of our debt maturing in the near- and medium-term and our ability to refinance our debt, or our plans to incur additional debt in the future;

• additions or departures of key management personnel;

• speculation in the press or investment community;

• equity issuances by us, or share resales by our stockholders or the perception that such issuances or resales may occur;

• actions by institutional stockholders; and

• general market and economic conditions.

Many of the factors listed above are beyond our control. Those factors may cause the market price of our common stock or preferred stock to decline significantly, regardless of our financial condition, results of operations and prospects. It is impossible to provide any assurance that the market price of our common stock or preferred stock will not fall in the future, and it may be difficult for holders to resell shares of our common stock or preferred stock at prices they find attractive, or at all. In the past, securities class action litigation has often been instituted against companies following periods of volatility in their stock price. This type of litigation could result in substantial costs and divert our management's attention and resources.

Our Series A Preferred Stock and Series A-4 Preferred Stock has not been rated.

We have not sought to obtain a rating for our Series A Preferred Stock or Series A-4 Preferred Stock. No assurance can be given, however, that one or more rating agencies might not independently determine to issue such a rating or that such a rating, if issued, would not adversely affect the market price of the Series A Preferred Stock or Series A-4 Preferred Stock. In addition, we may elect in the future to obtain a rating of the Series A Preferred Stock or Series A-4 Preferred Stock, which could adversely affect the market price of such preferred stock. Ratings only reflect the views of the rating agency or agencies issuing the ratings and such ratings could be revised downward, placed on a watch list or withdrawn entirely at the discretion of the issuing rating agency if in its judgment circumstances so warrant. Any such downward revision, placing on a watch list or withdrawal of a rating could have an adverse effect on the market price of the Series A Preferred Stock or Series A-4 Preferred Stock.

Security breaches and other disruptions could compromise our information and expose us to liability, which would cause our business and reputation to suffer.

In the ordinary course of our business, we collect and store sensitive data, including our proprietary business information and that of our tenants and clients and personally identifiable information of our employees, in our facilities and on our network. Despite our security measures, our information technology and infrastructure may be vulnerable to attacks by hackers or breached due to employee error, malfeasance or other disruptions. Any such breach could compromise our network and the information stored there could be accessed, publicly disclosed, lost or stolen. Any such access, disclosure or other loss of information could result in

legal claims or proceedings, disrupt our operations, damage our reputation, and cause a loss of confidence, which could adversely affect our business.

ITEM 2. PROPERTIES

As of December 31, 2016 , the Properties were located throughout the US and in Ontario, Canada and consisted of 226 MH communities, 87 RV communities, and 28 properties containing both MH and RV sites. As of December 31, 2016 , the Properties contained an aggregate of 117,376 developed sites comprised of 80,166 developed manufactured home sites, 20,916 annual RV sites (inclusive of both annual and seasonal usage rights), and 16,294 transient RV sites. There are approximately 10,616 additional MH and RV sites suitable for development. Most of the Properties include amenities oriented toward family and retirement living. Of the 341 Properties, 162 have more than 300 developed sites, with the largest having 2,072 developed MH and RV sites. See "Real Estate and Accumulated Depreciation, Schedule III", included in our Consolidated Financial Statements, for detail on Properties that are encumbered.

As of December 31, 2016 , the Properties had an occupancy rate of 96.2% excluding transient RV sites. Since January 1, 2016, the Properties have averaged an aggregate annual turnover of homes (where the home is moved out of the community) of approximately 2.0% and an average annual turnover of residents (where the resident-owned home is sold and remains within the community, typically without interruption of rental income) of approximately 6.1%. The average renewal rate for residents in our Rental Program was 64.2% for the year ended December 31, 2016 .

We believe that our Properties’ high amenity levels contribute to low turnover and generally high occupancy rates. All of the Properties provide residents with attractive amenities with most offering a clubhouse, a swimming pool, and laundry facilities. Many of the Properties offer additional amenities such as sauna/whirlpool spas, tennis, shuffleboard, basketball courts, and/or exercise rooms. Many RV communities offer incremental amenities including golf, pro shops, restaurants, zip lines, waterparks, watersports, and thematic experiences.

We have concentrated our communities within certain geographic areas in order to achieve economies of scale in management and operation. The Properties are principally concentrated in the Midwestern, Southern, Northeastern, Southeastern U.S. and Ontario, Canada. We believe that geographic diversification helps to insulate the portfolio from regional economic influences.

The following tables set forth certain information relating to the Properties as of December 31, 2016 . The occupancy percentage includes MH sites and annual/seasonal RV sites, and excludes transient RV sites.

OVERVIEW

We are a fully integrated, self-administered and self-managed REIT. As of December 31, 2016, we owned and operated or had an interest in a portfolio of properties located throughout the United States and Ontario, Canada, including 226 MH communities, 87 RV communities, and 28 properties containing both MH and RV sites. We have been in the business of acquiring, operating, developing, and expanding MH and RV communities since 1975. We lease individual sites with utility access for placement of manufactured homes and RVs to our customers. We are also engaged through SHS in the marketing, selling, and leasing of new and pre-owned homes to current and future residents in our communities. The operations of SHS support and enhance our occupancy levels, property performance, and cash flows.

EXECUTIVE SUMMARY

2016 Accomplishments:

• Total revenues for 2016 increased 23.6% to $833.8 million.

• In June 2016, we acquired all of the issued and outstanding shares of common stock of Carefree Communities Inc. ("Carefree") for $1.684 billion , our largest acquisition to date. The Carefree portfolio was comprised of 103 communities, located in prime coastal markets with over 27,000 total sites.

• In addition to Carefree, we acquired seven RV communities and one MH community during 2016 for total consideration of $89.7 million .

• Achieved Same Community NOI growth of 7.1% .

• FFO excluding certain items for the year ended December 31, 2016, was $3.79 per diluted share and OP unit as compared to $3.63 in the prior year, an increase of 4.4%.

• Sold 3,172 homes, a new single year record, and an increase of 27.8% over 2015.

• Gained 1,686 revenue producing sites.

• Achieved Same Community occupancy of 96.6% , an increase of 1.9% .

• Expanded 663 MH sites at eight communities.

• Closed two underwritten registered public offerings for proceeds net of offering related expenses totaling approximately $670 million.

Property Operations:

Occupancy in our Properties as well as our ability to increase rental rates directly affects revenues. Our revenue streams are predominantly derived from customers renting our sites on a long-term basis. Our Same Community properties continue to achieve revenue and occupancy increases which drive continued NOI growth. Home sales are at their historical high, and we expect to continue to increase the number of homes sold in our communities.

(2) We have engaged the sellers of Sunset Beach to continue to operate and maintain the property. Beginning January 1, 2022, we have the option to remove the sellers as operators via a payment based on certain operating performance metrics. Accordingly, total consideration of $28.3 million includes a contingent consideration liability of $9.8 million as of the acquisition date. The contingent liability was $10.0 million as of December 31, 2016.

Expansion Activity:

We expanded 663 MH sites at eight properties in 2016 . The total cost to construct the sites was approximately $13.5 million. We continue to expand our properties utilizing our inventory of owned and entitled land (approximately 10,600 to be developed sites) and expect to construct over 2,200 additional sites in 2017.

Capital Activity:

During 2016, we closed two underwritten registered public offering totaling 9.8 million shares of common stock with proceeds of approximately $670 million net of offering related expenses. The proceeds of these offerings were used to fund acquisitions and pay down our revolving lines of credit. Additionally, in June 2016, we issued 3.3 million shares of common stock for $225.0 million to the seller in the Carefree acquisition.

During 2015, we closed an underwritten registered public offering totaling 3.7 million shares of common stock with proceeds of $233.1 million net of offering related expenses. Proceeds from the capital were used to pay down our revolving lines of credit, which provided liquidity for future acquisitions and allowed us to reduce our leverage.

Refer to Note 9, "Equity and Mezzanine Securities," of our accompanying Consolidated Financial Statements for further information regarding capital activity.

Several of our acquisitions in these areas have been RV communities. Through our expansion into RV communities, we have experienced strong revenue growth. The age demographic of RV communities is attractive, as the population of retirement age baby boomers in the U.S. is growing. RV communities have become a trending vacation opportunity not only for the retiree population, but as an affordable vacation alternative for families.

NON-GAAP FINANCIAL MEASURES

In addition to the results reported in accordance with GAAP in our "Results of Operations" below, we have provided information regarding net operating income NOI and FFO as supplemental performance measures. We believe NOI and FFO are appropriate measures given their wide use by and relevance to investors and analysts following the real estate industry. 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. 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. In addition, NOI and FFO are commonly used in various ratios, pricing multiples/yields and returns and valuation calculations used to measure financial position, performance, and value.

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

FFO is defined by the National Association of Real Estate Investment Trusts ("NAREIT") as net income (loss) computed in accordance with 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. The Company 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 to 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 difference methods for calculating FFO, accordingly, our FFO may not be comparable to other REITs.

SUN COMMUNITIES, INC.

REAL PROPERTY OPERATIONS – SAME COMMUNITY

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

In order to evaluate the growth of the Same Communities, management has classified certain items differently than our GAAP statements. The reclassification difference between our GAAP statements and our Same Community portfolio is the reclassification of water and sewer revenues from income from real property to utilities. A significant portion of our utility charges are re-billed to our residents. We reclassify these amounts to reflect the utility expenses associated with our Same Community portfolio net of recovery.

The following tables reflect certain financial and other information for our Same Communities as of and for the years ended December 31, 2016 and 2015 :

(1) Year ended December 31, 2015 excludes $2.8 million of first year expenses for properties acquired in late 2014 and 2015 incurred to bring the properties up to Sun's operating standards. These costs did not meet our capitalization policy.

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

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

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

The 7.1% growth in NOI is primarily due to increased revenues of $26.8 million partially offset by additional expenses of $4.7 million .

Income from real property revenue consists of MH and RV site rent, and miscellaneous other property revenues. The 6.1% growth in income from real property was due to a combination of factors. Revenue from our MH and RV portfolio increased $24.9 million due to monthly base rent per site increases of 3.2% , a 1.9% increase in occupancy, and the increased number of occupied vacation rental sites. Additionally, other revenues increased $1.8 million primarily due to increases in property tax revenues, trash income, cable television royalties, and month-to-month fees.

SUN COMMUNITIES, INC.

Property operating expenses increased approximately $4.7 million , or 3.7% , compared to 2015. The increase is primarily due to increased real estate taxes of $2.7 million and increased payroll and benefits of $2.2 million, partially offset by reduced legal, tax, and insurance expenses.

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

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

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

The 9.1% growth in NOI is primarily due to increased revenues of $22.1 million partially offset by a $3.7 million increase in expenses.

Income from real property revenue consists of MH and RV site rent, and miscellaneous other property revenues. The 7.6% growth in income from real property was due to a combination of factors. Revenue from our MH and RV portfolio increased $18.3 million due to monthly base rent per site increases of 3.3% , a 2.7% increase in occupancy, and the increased number of occupied home sites. Additionally, other revenues increased $1.8 million primarily due to increases in month to month fees, utilities income, trash income, and cable television royalties.

Property operating expenses increased approximately $3.7 million , or 4.2% , compared to 2014. Of that increase, supplies and repair expense increased $0.6 million primarily related to higher landscaping and tree trimming. Utilities increased $0.8 million primarily as a result of increased electric and trash removal costs. Legal, taxes, and insurance expenses increased $0.6 million primarily related to an increased property and casualty insurance.

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

The 18.5% growth in NOI is primarily a result of increased rental income throughout the year. While the number of occupied rentals as of December 31, 2015, reflects a decline due to disposition of 20 communities during 2015, the rental income associated with the majority of those communities was earned through November. We renew approximately 60% of our rental home leases primarily at current market rates or above existing rates.

The $1.7 million increase in operating and maintenance expenses was primarily a result of a $1.3 million increase in repair and refurbishment expenses, of which $0.7 million was due to increased refurbishment costs related to occupant turnover and $0.5 million was due to increased repair costs on occupied home rentals. In addition, insurance and personal property and use taxes increased by $0.4 million.

Ancillary revenues, net for 2015 increased $1.8 million as compared to the same period in 2014, primarily due to increased vacation rental income of $1.7 million.

Interest income for 2015 increased by $1.5 million as compared to 2014, primarily due to an increase in interest income from collateralized receivables of $1.5 million related to an increase in our note portfolio.

Brokerage commissions and other revenues, net for 2015 increased by $1.2 million as compared to 2014, primarily due to an increase in the number of brokered homes sold.

Home selling expenses for 2015 increased $2.2 million as compared to 2014. This change represents a 43% increase, consistent with the increase in home sales revenues and the Company's new single year record for home sales volumes in 2015.

General and administrative expenses for 2015 increased by $10.1 million as compared to 2014, primarily due to increased expenses related to salaries, wages and related taxes of $4.7 million as a result of our acquisitions and increased headcount year over year, increased deferred compensation of $2.2 million, increased training, travel, and office expenses of $0.9 million, increased expenses for software support and maintenance, director fees, and regulatory fees of $0.7 million, increased consulting costs of $0.5 million, increased corporate insurance premiums of $0.4 million, and increased other miscellaneous expenses of $0.7 million.

Depreciation and amortization expenses increased by $43.9 million in 2015 as compared to 2014, primarily a result of additional depreciation and amortization of $33.3 million primarily related to our newly acquired properties (See Note 2 in our Consolidated Financial Statements), an additional $4.6 million related to depreciation on investment property for use in our rental program, an additional $1.6 million related to depreciation on investment property for our vacation rental property, and an additional $4.4 million related to the amortization of in-place leases and promotions.

Asset impairment charge of $0.8 million during 2014, was the result of an impairment loss recorded on a long-lived asset for our MH and RV community in La Feria, Texas. We did not recognize any asset impairment charge during 2015.

SUN COMMUNITIES, INC.

Gain on disposition of properties, net for 2015 increased by $107.7 million as compared to 2014, primarily as a result of the sale of 20 properties during 2015, compared to the sale of 10 properties during the year ended December 31, 2014 (see Note 2, "Real Estate Acquisitions and Dispositions," in our accompanying Consolidated Financial Statements for additional information).

Gain on settlement of $4.5 million for 2014, was the result of a settlement reached with the sellers of 10 RV communities that we acquired in February 2013. The settlement was related to various warranties, representations, and indemnities included in the agreements under which we acquired the RV communities, including a covenant made by the sellers related to the 2012 revenue of the acquired properties. No such gain was recorded during 2015.

Deferred tax expense of $1.0 million for 2015, was the result of a valuation allowance increase in relation to management's assumptions regarding realization of operating loss carryforwards at SHS. We had no such adjustment during 2014. Refer to Note 12, "Income Taxes," in our accompanying Consolidated Financial Statements for additional information.

Income from affiliate transactions for 2015 increased by $6.3 million as compared to 2014. During 2015, we received a $7.5 million distribution from Origen as part of its dissolution. In 2014, we received distributions of $1.2 million from Origen on our common stock.

Preferred stock redemption costs for 2015 were $4.3 million , as a result of a repurchase agreement with certain holders of the Company's Series A-4 Preferred Stock (see Note 9, "Equity and Mezzanine Securities" in our accompanying Consolidated Financial Statements for additional information). We had no similar transactions during 2014.

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

(2) These costs represent first year expense incurred to bring acquired properties up to the Company's operating standards, including items such as tree trimming and painting costs that did not meet the Company's capitalization policy. The Company incurred $2.8 million of these first year expenses for the year ended December 31, 2015. These costs are expected to become more significant in connection with the size of our acquisitions, and are therefore included as an FFO adjustment for the year ended December 31, 2016. Had a similar adjustment been made, FFO attributable to Sun Communities, Inc. common stockholders and dilutive convertible securities per share excluding certain items would have been $3.68 for the years ended December 31, 2015. These costs were insignificant for the year ended December 31, 2014.

(3) Line item is included within Other expenses, net on the Statements of Operations in our accompanying Consolidated Financial Statements.

SUN COMMUNITIES, INC.

LIQUIDITY AND CAPITAL RESOURCES

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

During the year ended December 31, 2016, we acquired 111 communities, 103 of which were part of the Carefree acquisition. See Note 2, "Real Estate Acquisitions and Dispositions" and Note 8, "Debt and Lines of Credit" in our accompanying Consolidated Financial Statements for additional information regarding our acquisitions and related debt transactions in 2016. Subject to market conditions, we intend to continue to look for opportunities to expand our development pipeline and acquire existing communities. We finance the acquisitions through available cash, secured financing, draws on our unsecured lines of credit, the assumption of existing debt on properties, and the issuance of certain equity securities. We will continue to evaluate acquisition opportunities that meet our criteria for acquisition.

We also intend to continue to strengthen our capital and liquidity positions by focusing on our core fundamentals, which are generating positive cash flows from operations, maintaining appropriate debt levels and leverage ratios, and controlling overhead costs. We intend to meet our liquidity requirements through available cash balances, cash flows generated from operations, draws on our credit facility, and the use of debt and equity offerings under our shelf registration statement.

Our capital expenditures include expansion and development, lot modifications, recurring capital expenditures and rental home purchases. For the years ended December 31, 2016 and 2015, expansion and development activities of $48.0 million and $28.7 million, respectively, related to costs consisting primarily of construction and other costs necessary to complete home site improvements.

For the years ended December 31, 2016 and 2015, lot modification expenditures were $19.0 million and $14.0 million, respectively. These expenditures improve asset quality in our communities and are incurred when an existing home is removed 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 codes, include items such as new foundations, driveways, and utility upgrades.

For the years ended December 31, 2016 and 2015, recurring capital expenditures were $17.6 million and $20.3 million, respectively, related to our continued commitment to upkeep of our properties. We do not expect a decline in our recurring capital expenditures in future periods.

During the year ended December 31, 2016 , we invested $13.8 million in the acquisition of homes intended for the Rental Program net of proceeds from third-party financing from homes sales. Expenditures for 2017 will depend upon the condition of the markets for repossessions and new home sales, as well as rental homes. We finance new home purchases with a $12.0 million manufactured home floor plan facility. Our ability to purchase homes for sale or rent may be limited by cash received from third-party financing of our home sales, available manufactured home floor plan financing and working capital available on our lines of credit.

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

	Year Ended December 31, — 2016		2015		2014
Net Cash Provided by Operating Activities	$ 238,693		$ 182,263		$ 133,320

Cash and cash equivalents decreased by $36.9 million from $45.1 million as of December 31, 2015 , to $8.2 million as of December 31, 2016 .

Operating Activities

Net cash provided by operating activities increased by $56.4 million from $182.3 million for the year ended December 31, 2015 to $238.7 million for the year ended December 31, 2016 .

SUN COMMUNITIES, INC.

Our net cash flows provided by operating activities from continuing operations may be adversely impacted by, among other things: (a) the market and economic conditions in our current markets generally, and specifically in metropolitan areas of our current markets; (b) lower occupancy and rental rates of our properties; (c) increased operating costs, such as wage and benefit costs, insurance premiums, real estate taxes and utilities, that cannot be passed on to our tenants; (d) decreased sales of manufactured homes; and (e) current volatility in economic conditions and the financial markets. See Part I, Item 1A, “Risk Factors” in this Annual Report on Form 10-K.

Investing Activities

Net cash used for investing activities was $1.6 billion for the year ended December 31, 2016 , compared to $413.2 million for the year ended December 31, 2015 . The increase is primarily due to increased cash used for the acquisition of Carefree Communities.

Financing Activities

Net cash provided by financing activities was $1.3 billion for the year ended December 31, 2016 , compared to $192.5 million for the year ended December 31, 2015 . The increase is primarily due to equity offerings and new debt issuances in 2016 to fund the Carefree Communities acquisition and for other corporate purposes. Refer to Note 8, "Debt and Lines of Credit" and Note 9, "Equity and Mezzanine Securities" in our accompanying Consolidated Financial Statements for additional information.

Financial Flexibility

In August 2015 we amended and restated our senior revolving credit facility with Citibank, N.A. and certain other lenders in the amount of $450.0 million, comprised of a $392.0 million revolving loan and $58.0 million term loan (the "Facility"). The Facility has a four year term ending August 19, 2019, which can be extended for two additional six-month periods at our option, subject to the satisfaction of certain conditions as defined in the credit agreement. The credit agreement also provides for, subject to the satisfaction of certain conditions, additional commitments in an amount not to exceed $300.0 million. If additional borrowings are made pursuant to any such additional commitments, the aggregate borrowing limit under the Facility may be increased up to $750.0 million. The Facility bears interest at a floating rate based on the Eurodollar rate plus a margin that is determined based on our leverage ratio calculated in accordance with the credit agreement, which can range from 1.40% to 2.25% for the revolving loan and 1.35% to 2.20% for the term loan. As of December 31, 2016 , the margin on our leverage ratio was 1.45% and 1.40% on the revolving and term loans, respectively. We had $42.3 million in borrowings on the revolving loan and $58.0 million on the term loan totaling $100.3 million in borrowings as of December 31, 2016, with a weighted average interest rate of 2.14%. As of December 31, 2015, there was $25.0 million outstanding under our previous credit facility.

The Facility provides us with the ability to issue letters of credit. Our issuance of letters of credit does not increase our borrowings outstanding under our line of credit, but it does reduce the borrowing amount available. At December 31, 2016 and December 31, 2015, $4.6 million and $3.4 million, respectively, of availability was used to back standby letters of credit.

Pursuant to the terms of the Facility, we are subject to various financial and other covenants. We are currently in compliance with these covenants. The most restrictive financial covenants for the Facility are as follows:

Covenant	Requirement	As of 12/31/16
Maximum Leverage Ratio	< 65.0%	40.5%
Minimum Fixed Charge Coverage Ratio	> 1.40	2.50
Minimum Tangible Net Worth (in thousands)	>$2,475,365	$3,454,032
Maximum Dividend Payout Ratio	< 95.0%	69.6%

Market and Economic Conditions

Changes in the Canadian dollar against the U.S. dollar, the U.S. interest rate environment, oil price fluctuations, a new U.S. President, uncertain tax and economic plans in Congress, and turmoil in emerging markets have created uncertainty and volatility in the U.S. and global economies. Continued economic uncertainty, both nationally and internationally, causes increased volatility in investor confidence thereby creating similar volatility in the availability of both debt and equity capital in the financial markets. The U.S. Federal Reserve has predicted that more interest rate hikes will occur in 2017 thus raising borrowing costs for consumers and businesses. While the U.S. economy looks poised for self-sustaining growth, the global economy is seeing modest improvement led by developed countries. Continued economic uncertainty, both domestically and internationally, causes increased volatility in investor confidence thereby creating similar volatility in the availability of both debt and equity capital. If such volatility is experienced in future periods, our industry, business and results of operations may be adversely impacted.

We anticipate meeting our long-term liquidity requirements, such as scheduled debt maturities, large property acquisitions, expansion and development of communities, and Operating Partnership unit redemptions through the issuance of certain debt or equity securities and/or the collateralization of our properties. At December 31, 2016, we had 152 unencumbered properties, of which 56 of these unencumbered properties support the borrowing base for our $450.0 million line of credit. From time to time, we may also issue shares of our capital stock, issue equity units in our Operating Partnership, obtain debt financing, or sell selected assets. Our ability to finance our long-term liquidity requirements in such a manner will be affected by numerous economic factors affecting the MH and RV community industry at the time, including the availability and cost of mortgage debt, our financial condition, the operating history of the properties, the state of the debt and equity markets, and the general national, regional, and local economic conditions. When it becomes necessary for us to approach the credit markets, the volatility in those markets could make borrowing more difficult to secure, more expensive, or effectively unavailable. See “Risk Factors” in Part I, Item 1A in this Annual Report on Form 10-K. If we are unable to obtain additional debt or equity financing on acceptable terms, our business, results of operations and financial condition would be adversely impacted.

Contractual Cash Obligations

Our primary long-term liquidity needs are principal payments on outstanding indebtedness. As of December 31, 2016 , our outstanding contractual obligations, including interest expense, were as follows:

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Our Consolidated Financial Statements are prepared in accordance with U.S. generally accepted accounting principles ("GAAP"), which require the use of estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses in the periods presented. We believe that the accounting estimates employed are appropriate and resulting balances are reasonable; however, due to inherent uncertainties in making estimates, actual results could differ from the original estimates, requiring adjustments to these balances in future periods.

The critical accounting estimates that affect the Consolidated Financial Statements and that use judgments and assumptions are listed below. In addition, the likelihood that materially different amounts could be reported under varied conditions and assumptions is discussed.

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 also 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, development, 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.

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.

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).

Notes and Other Receivables

We make financing available 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 purchased by the Company as well as transferred loans that have not met the requirements for sale accounting which are presented herein as collateralized receivables. For purposes of accounting policy, all notes receivable are considered one homogeneous segment, 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, 2016 and 2015 . 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.

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 impairments. No loans were considered impaired as of December 31, 2016 and 2015 .

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; loan value to the collateralized asset; total debt to income ratio; length of employment; previous landlord references; and FICO 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.

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.

Refer to Note 1, "Significant Accounting Policies" of our accompanying Consolidated Financial Statements for additional information on critical accounting policies and estimates.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market risk is the exposure to loss resulting from changes in market factors such as interest rates, foreign currency exchange rates, commodity prices, and equity prices.

Interest Rate Risk

Our principal market risk exposure is interest rate risk. We mitigate this risk by maintaining prudent amounts of leverage, minimizing capital costs, and interest expense while continuously evaluating all available debt and equity resources and following established risk management policies and procedures, which include the periodic use of derivatives. Our primary strategy in entering into derivative contracts is to minimize the variability that interest rate changes could have on our future cash flows. From time to time, we employ derivative instruments that effectively convert a portion of our variable rate debt to fixed rate debt. We do not enter into derivative instruments for speculative purposes.

We have two interest rate cap agreements with a total notional amount of $159.7 million as of December 31, 2016 . The first interest rate cap agreement has a cap rate of 9.00% , a notional amount of $150.1 million and a termination date of April 2018 . The second interest rate cap agreement has a cap rate of 11.02% , a notional amount of $9.6 million and a termination date of May 2023 .

Our remaining variable rate debt totals $256.0 million and $183.3 million as of December 31, 2016 and 2015 , respectively, and bears interest at Prime or various LIBOR rates. If Prime or LIBOR increased or decreased by 1.0%, we believe our interest expense would have increased or decreased by approximately $3.0 million and $2.2 million as of December 31, 2016 and 2015 , respectively, based on the $299.1 million and $223.2 million average balances outstanding under our variable rate debt facilities, respectively.

Foreign Currency Exchange Rate Risk

Foreign currency exchange rate risk is the risk that fluctuations in currencies against the U.S. dollar will negatively impact our results of operations. We are exposed to foreign currency exchange rate risk as a result of remeasurement and translation of the assets and liabilities of our Canadian properties into U.S. dollars. Fluctuations in foreign currency exchange rates can therefore create volatility in our results of operations and may adversely affect our financial condition.

ITEM 9A. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

We maintain disclosure controls and procedures designed to provide reasonable assurance that information required to be disclosed in reports filed under the Exchange Act is recorded, processed, summarized and reported within the specified time periods and accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

Our management, with the participation of our CEO and CFO, evaluated the effectiveness of our disclosure controls and procedures (pursuant to Rules 13a-15(e) or 15d-15(e) of the Exchange Act) at December 31, 2016. Based upon this evaluation, our CEO and CFO concluded that our disclosure controls and procedures were effective as of December 31, 2016.

Management's Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining effective internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. This system is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements for external purposes in accordance with U.S. GAAP. Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, misstatements due to error or fraud may not be prevented or detected on a timely basis.

Our management performed an assessment of the effectiveness of our internal control over financial reporting at December 31, 2016, utilizing the criteria discussed in the “Internal Control - Integrated Framework (2013)” issued by the Committee of Sponsoring Organizations of the Treadway Commission. The objective of this assessment was to determine whether our internal control over financial reporting was effective at December 31, 2016. Based on management's assessment, we have concluded that our internal control over financial reporting was effective at December 31, 2016.

The effectiveness of our internal control over financial reporting has been audited by Grant Thornton LLP, an independent registered public accounting firm, as stated in its report which is included herein.

Changes in Internal Control Over Financial Reporting

There have been no changes in our internal control over financial reporting during the quarter ended December 31, 2016 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders

Sun Communities, Inc.

We have audited the accompanying consolidated balance sheets of Sun Communities, Inc. (a Maryland corporation) and subsidiaries (the “Company”) as of December 31, 2016 and 2015, and the related consolidated statements of operations, comprehensive income, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2016. Our audit of the basic consolidated financial statements included the financial statement schedule listed in the index appearing under Item 15. These financial statements and financial statement schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements and financial statement schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Sun Communities, Inc. and subsidiaries as of December 31, 2016 and 2015, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2016 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the related financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Company’s internal control over financial reporting as of December 31, 2016, based on criteria established in the 2013 Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated February 23, 2017 expressed an unqualified opinion.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders

Sun Communities, Inc.

We have audited the internal control over financial reporting of Sun Communities, Inc. (a Maryland corporation) and subsidiaries (the “Company”) as of December 31, 2016, based on criteria established in the 2013 Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2016, based on criteria established in the 2013 Internal Control-Integrated Framework issued by COSO.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements of the Company as of and for the year ended December 31, 2016, and our report dated February 23, 2017 and expressed an unqualified opinion on those financial statements.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Significant Accounting Policies

Business

Sun Communities, Inc., a Maryland corporation, and all wholly-owned or majority-owned and controlled subsidiaries, including Sun Communities Operating Limited Partnership (the "Operating Partnership"), and Sun Home Services, Inc. ("SHS") are referred to herein as the “Company,” “us,” “we,” and “our”. We 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 ("U.S."). As of December 31, 2016 , we owned and operated a portfolio of 341 properties located in 29 states and Ontario, Canada (collectively the “Properties”), including 226 MH communities, 87 RV communities, and 28 Properties containing both MH and RV sites. As of December 31, 2016 , the Properties contained an aggregate of 117,376 developed sites comprised of 80,166 developed MH sites, 20,916 annual RV sites (inclusive of both annual and seasonal usage rights), and 16,294 transient RV sites. There are approximately 10,616 additional MH and RV sites suitable for development.

Principles of Consolidation

The accompanying Consolidated 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 considered 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 U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions related to the reported amounts included in our Consolidated Financial Statements and accompanying footnotes thereto. Actual results could differ from those estimates.

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, development, 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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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 $10.1 million and $41.4 million as of December 31, 2016 and 2015 , respectively.

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 6 , "Investment in Affiliates," 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 purchased by the Company as well as transferred loans that have not met the requirements for sale accounting which are presented herein as collateralized receivables. For purposes of accounting policy, all notes receivable are considered one homogenous segment, 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.

SUN COMMUNITIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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.

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. A specific allowance is estimated on the past due loans based on historical delinquency data and current delinquency levels.

Restricted Cash

Restricted cash consists of amounts held in deposit for tax, insurance and repair escrows held by lenders in accordance with certain debt agreements. At December 31, 2016 and 2015 , $17.1 million and $140.7 million of restricted cash, respectively, was included as a component of Other assets, net on the Consolidated Balance Sheets.

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, 2016 and 2015 , the carrying amounts of the identified intangible assets are included in Other assets, net on the Consolidated Balance Sheets. See Note 5 , "Intangible Assets," for additional information.

Deferred Taxes

We are subject to certain state taxes that are considered to be income taxes and have certain subsidiaries that are taxed as regular corporations for U.S. (i.e., federal, state, local, etc.) and non-U.S. income tax purposes. 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 in certain subsidiaries, including those domiciled in foreign jurisdictions, which may be realized in future periods if the respective subsidiary generates sufficient taxable income. 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 12 , "Income Taxes," 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,

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

"Modifications and Extinguishments." Refer to Note 17, "Recent Accounting Pronouncements," regarding our adoption of FASB Accounting Standards Update ("ASU") 2015-03, and the presentation of deferred financing costs in our Consolidated Balance Sheets as of December 31, 2016 and 2015.

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. 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 10 , "Share-Based Compensation" 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, debt and a contingent consideration liability. 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 16 , "Fair Value of Financial Instruments," for additional information regarding the estimates and assumptions used to estimate the fair value of each financial instrument class.

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 real estate taxes collected from residents and remitted to taxing authorities in revenue.

Advertising Costs

Advertising costs are expensed as incurred. As of December 31, 2016 , 2015 and 2014 , we had advertising costs of $4.2 million , $3.9 million and $3.2 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, four to seven years for computer hardware and software, and seven to 15 years for intangible assets.

Foreign Currency

The assets and liabilities of our Canadian operations, where the functional currency is the Canadian dollar, are translated into U.S. dollars using the exchange rate in effect as of the balance sheet date. Income statement amounts are translated at the average exchange rate prevailing during the period. The resulting translation adjustments are recorded as a component of accumulated other comprehensive income (loss).

Foreign currency exchange gains and losses arising from fluctuations in currency exchange rates on transactions and the effects of remeasurement of monetary balances denominated in currencies other than the functional currency are recorded in earnings. For the year ended December 31, 2016, we recorded a foreign currency exchange loss of $5.0 million within Other expenses, net

on our Consolidated Statements of Operations. We had no foreign currency exchange impacts for the years ended December 31, 2015 and 2014.

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. As of December 31, 2016 and 2015, the fair value of our derivatives was zero . See Note 15 , "Derivative Instruments and Hedging Activities" for additional information.

2 . Real Estate Acquisitions and Dispositions

2016 Acquisitions

Carefree Acquisition

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

The aggregate purchase price for the acquisition was $1.68 billion . At the closing, the Company issued the Seller 3,329,880 shares of its common stock (the "Acquisition Shares") at an issuance price of $67.57 per share (or $225.0 million in common stock), and the Operating Partnership paid the balance of the purchase price, or $1.5 billion , in cash. Approximately $1.0 billion of the cash payment was applied simultaneously to pay off debt on the properties owned by Carefree Communities. The Operating Partnership funded the cash portion of the purchase price in part with the proceeds of the Fannie Mae financing and the Northwestern Mutual Life Insurance Company financing described in Note 8, "Debt and Lines of Credit."

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

We have allocated the "Investment in property" balances for Carefree Communities to the respective balance sheet line items upon preliminary completion of a purchase price allocation in accordance with the FASB ASC Topic 805 - Business Combinations.

At Acquisition Date	Carefree
Investment in property	$ 1,670,981

2016 Other Acquisitions:

In December 2016, we acquired Lake Josephine RV Resort ("Lake Josephine"), a RV resort with 178 sites located in Sebring, Florida.

In October 2016, we acquired Adirondack Gateway Campground RV Resort ("Adirondack Gateway"), a RV resort with 347 sites located in Gansevoort, New York. We recognized a gain on the acquisition of Adirondack Gateway of $0.5 million within Other expenses, net in our Consolidated Statements of Operations, as the fair value of the consideration transferred by us was less than the fair value of the identifiable net assets acquired.

Also in October 2016, we acquired Jellystone Park Camp Resort ("Jellystone Larkspur"), a RV resort with 148 sites located in Larkspur, Colorado.

In September 2016, we acquired Petoskey RV Resort ("Petoskey"), a RV resort with 78 sites located in Petoskey, Michigan.

In August 2016, we acquired Sunset Beach Resort ("Sunset Beach") in Cape Charles, Virginia. The sellers of Sunset Beach were engaged by the Company to continue to operate and maintain the property. Beginning January 1, 2022, the Company has the option to remove the sellers as operators via a payment based on certain operating performance metrics. Accordingly, total consideration of $28.3 million as of the acquisition date includes a contingent consideration liability of $9.8 million .

The contingent consideration liability represents the present value of the contingent payment estimated at acquisition closing, based on projected future operating performance metrics. The contingent payment is formula-driven, and not capped. The contingent consideration liability will be re-measured at each reporting date, with changes in fair value adjusted through earnings, until the contingency is resolved. The final contingent payment could be materially different from the initial estimate.

In June 2016, we acquired Pecan Park RV Resort ("Pecan Park"), a RV resort with 183 sites located in Jacksonville, Florida.

In March 2016, we acquired Hill Country Cottage and RV Resort ("Hill Country"), a RV resort with 356 sites located in New Braunfels, Texas.

Dispositions

There were no property dispositions during 2016, however, during the fourth quarter we terminated a ground lease arrangement in one of the communities acquired in the Carefree transaction. No gain or loss resulted from the ground lease termination.

During the year ended December 31, 2015 , we disposed of 17 MH communities and 3 MH and RV combined communities. Pursuant to Accounting Standards Update ("ASU") 2014-08, "Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360) - Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity," the disposals of the communities do not qualify for presentation as a discontinued operation, as the sales do not have a major impact on our operations and financial results and do not represent a strategic shift. A gain of $125.4 million was recorded in Gain on disposition of properties, net in our Consolidated Statements of Operations. At December 31, 2015, we held $ 126.3 million related to certain of these dispositions in escrow as a result of an Internal Revenue Code Section 1031 transaction included in Other assets, net. During 2016, $37.6 million of the balance held in escrow was used to fund acquisitions. The remaining $88.7 million of the escrow balance reverted to us.

3 . Collateralized Receivables and Transfers of Financial Assets

We completed various transactions with an unrelated entity involving our notes receivable under which we received cash proceeds in exchange for relinquishing our right, title, and interest in certain notes receivable. We have no further obligations or rights with respect to the control, management, administration, servicing, or collection of the installment notes receivable. However, we are subject to certain recourse provisions requiring us to purchase the underlying homes collateralizing such notes, in the event of a note default and subsequent repossession of the home by the unrelated entity. The recourse provisions are considered to be a form of continuing involvement, and therefore these transferred loans did not meet the requirements for sale accounting. We continue to recognize these transferred loans on our balance sheet and refer to them as collateralized receivables. The proceeds from the transfer have been recognized as a secured borrowing.

In the event of a note default and subsequent repossession of a manufactured home by the unrelated entity, the terms of the agreement require us to repurchase the manufactured home. Default is defined as the failure to repay the installment note receivable according

F - 21

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

to contractual terms. The repurchase price is calculated as a percentage of the outstanding principal balance of the collateralized receivable, plus any outstanding late fees, accrued interest, legal fees, and escrow advances associated with the installment note receivable. The percentage used to determine the repurchase price of the outstanding principal balance on the installment note receivable is based on the number of payments made on the note. In general, the repurchase price is determined as follows:

Number of Payments	Repurchase %
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 %
120 or more	50 %

The transferred assets have been classified as Collateralized receivables, net and the cash proceeds received from these transactions have been classified as "Secured borrowings on collateralized receivables" within the Consolidated Balance Sheets. The balance of the collateralized receivables was $143.9 million (net of allowance of $0.6 million ) and $139.8 million (net of allowance of $0.7 million ) as of December 31, 2016 , and December 31, 2015 , respectively. The receivables have a weighted average interest rate and maturity of 10.0% and 15.7 years as of December 31, 2016 , and 10.2% and 15.6 years as of December 31, 2015 .

The outstanding balance on the secured borrowing was $144.5 million and $140.4 million as of December 31, 2016 , and December 31, 2015 , respectively.

The collateralized receivables earn interest income, and the secured borrowings accrue interest expense at the same interest rates. The amount of interest income and expense recognized was $14.0 million , $13.2 million , and $11.8 million for the years ended December 31, 2016 , 2015 , and 2014 , respectively.

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

	Year Ended — December 31, 2016		December 31, 2015

Installment Notes Receivable on Manufactured Homes

The installment notes of $59.3 million (net of allowance of $0.2 million ) and $20.4 million (net of allowance of $0.2 million ) as of December 31, 2016 and December 31, 2015 , respectively, are collateralized by manufactured homes. The notes represent financing provided by us to purchasers of manufactured homes primarily located in our communities and require monthly principal and interest payments. The notes have a net weighted average interest rate (net of servicing costs) and maturity of 8.3% and 16 years as of December 31, 2016 , and 8.6% and 10.0 years as of December 31, 2015 . The increase in weighted average maturity from 10.0 years to 16.0 years is the result of a shift to longer maturities in our financed sales of manufactured homes in 2016, as well as our acquired notes having longer maturities than our previous average.

The change in the aggregate gross principal balance of the installment notes receivable is as follows (in thousands):

5 . Intangible Assets

Our intangible assets include ground leases and in-place leases from acquisitions, franchise fees, and other intangible assets. These intangible assets are recorded in Other assets, net on the Consolidated Balance Sheets.

During 2016, as part of the Carefree acquisition purchase price allocation, we recorded $33.3 million of intangible assets associated with ground leases. These ground leases relate to five communities where contractual base rents are below market rents and therefore give rise to future economic benefits over the remaining lease terms.

6 . Investment in Affiliates

Origen Financial Services, LLC (“OFS LLC”)

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

Origen Financial, Inc. (“Origen”)

Through Sun OFI, LLC, a taxable REIT subsidiary, we previously owned 5,000,000 shares of common stock of Origen, which approximated an ownership interest of 19.3% . During the third quarter of 2016, we sold all 5,000,000 shares of common stock in Origen to an unrelated party for aggregate proceeds of $0.5 million. The carrying value of our investment prior to the sale was zero . During 2015, we received a distribution of $7.5 million from Origen.

7 . Consolidated Variable Interest Entities

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

Other VIEs that are consolidated include: Rudgate Village SPE, LLC; Rudgate Clinton SPE, LLC; Rudgate Clinton Estates SPE, LLC (collectively “Rudgate”); and Wildwood Village Mobile Home Park ("Wildwood"). We evaluated our arrangements with these properties under the guidance set forth in FASB Accounting Standards Codification ("ASC") Topic 810 " Consolidation. " We concluded that Rudgate 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 our accompanying Consolidated Financial Statements.

Collateralized Term Loans

During the fourth quarter of 2016, we repaid a total of $79.1 million aggregate principal amount of collateralized term loans that were due to mature during 2017, releasing 10 communities. As a result of certain of these transactions, we recognized a loss on extinguishment of debt of $1.1 million that is reflected in our Consolidated Statements of Operations.

In October 2016, one subsidiary entered into a new promissory note totaling $58.5 million with PNC Bank, as lender with Freddie Mac. It bears an interest rate of 3.33% and has a seven -year term. The repayment of the loan is interest only for the entire term.

In September 2016, 15 subsidiaries of the Operating Partnership entered into 15 different promissory notes totaling $139.0 million with PNC Bank, as lender (the "Freddie Mac Financing"). Five of the loans totaling $70.2 million bear interest at a rate of 3.93%

and have ten -year terms. The remaining ten loans totaling $68.8 million bear interest at a rate of 3.75% and have seven -year terms. The Freddie Mac Financing provides for principal and interest payments to be amortized over 30 years.

In September 2016, proceeds from the Freddie Mac Financing described above and the underwritten registered public equity offering described in Note 9, "Equity and Mezzanine Securities" were utilized to repay $62.1 million in mortgage loans and $300.0 million on our revolving loan under our senior revolving credit facility.

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

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

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

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

In December 2015, we paid off $85.6 million of CMBS debt secured by eight communities. The loans had a stated maturity of July 2016 and an interest rate of 5.32% .

In August 2015, we entered into an agreement to borrow $87.0 million in mortgage debt that is secured by five communities at an interest rate of 4.06% for a term of 25 years . This loan closed in two separate closings. We completed the first closing for $51.2 million secured by four communities in September 2015 and the second closing for $35.8 million secured by one community in December 2015.

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

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

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

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

The collateralized term loans totaling $2.8 billion as of December 31, 2016, are secured by 189 properties comprised of 75,118 sites representing approximately $3.4 billion of net book value.

Secured Borrowing

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

Preferred OP units

Included in preferred OP units is $34.7 million of Aspen preferred OP units issued by the Operating Partnership which are convertible into shares of the Company's common stock. Subject to certain limitations, at any time prior to January 1, 2024, the holder of each Aspen preferred OP unit at its option may convert such Aspen preferred OP unit into: (a) if the average closing price of our common stock for the 10 preceding trading days is $68.00 per share of less, 0.397 common OP units, or (b) if the average closing price of our common stock for the 10 preceding trading days is greater than $68.00 per share, the number of common OP units determined by dividing (i) the sum of (A) $27.00 plus (B) 25% of the amount by which the average closing price of our common stock for the 10 preceding trading days exceeds $68.00 per share, by (ii) the average closing price of our common stock for the 10 preceding trading days. The current preferred rate is 6.5% . On January 2, 2024, we are required to redeem all Aspen preferred OP units that have not been converted to common OP units.

Also included in preferred OP units is $11.2 million of Series B-3 preferred OP units, which are not convertible. Subject to certain limitations, (a) during the 90-day period beginning on each of the tenth through fifteenth anniversaries of the issue date of the applicable Series B-3 preferred OP units, (b) at any time after the fifteenth anniversary of the issue date of the applicable Series B-3 preferred OP units, or (c) after our receipt of notice of the death of the electing holder of a Series B-3 preferred OP unit, each holder of Series B-3 preferred OP units may require us to redeem such holder's Series B-3 preferred OP units at the redemption price of $100.00 per unit. In addition, at any time after the fifteenth anniversary of the issue date of the applicable Series B-3 preferred OP units we may redeem, at our option, all of the Series B-3 preferred OP units of any holder thereof at the redemption price of $100.00 per unit.

Lines of Credit

In August, 2015, we amended and restated our senior revolving credit facility with Citibank, N.A. and certain other lenders in the amount of $450.0 million , comprised of a $392.0 million revolving loan and $58.0 million term loan (the "Facility"). The Facility has a four year term ending August 19, 2019 , which can be extended for two additional six-month periods at our option, subject to the satisfaction of certain conditions as defined in the credit agreement. The credit agreement also provides for, subject to the satisfaction of certain conditions, additional commitments in an amount not to exceed $300.0 million . If additional borrowings are made pursuant to any such additional commitments, the aggregate borrowing limit under the Facility may be increased up to $750.0 million . The Facility bears interest at a floating rate based on the Eurodollar rate plus a margin that is determined based on our leverage ratio calculated in accordance with the credit agreement, which can range from 1.40% to 2.25% for the revolving loan and 1.35% to 2.20% for the term loan. As of December 31, 2016 , the margin on our leverage ratio was 1.45% and 1.40% on the revolving and term loans, respectively. We had $42.3 million borrowings on the revolving loan and $58.0 million in borrowings on the term loan totaling $100.3 million in borrowings as of December 31, 2016 , with a weighted average interest rate of 2.14% . As of December 31, 2015, there was $25.0 million outstanding under our previous credit facility.

The Facility provides us with the ability to issue letters of credit. Our issuance of letters of credit does not increase our borrowings outstanding under our line of credit, but does reduce the borrowing amount available. At December 31, 2016 and December 31, 2015 , approximately $4.6 million and $3.4 million , respectively, of availability was used to back standby letters of credit.

We have a $12.0 million manufactured home floor plan facility renewable indefinitely until our lender provides us at least a twelve month notice of its intent to terminate the agreement. The interest rate is 100 basis points over the greater of the prime rate as quoted in The Wall Street Journal on the first business day of each month or 6.0% . At December 31, 2016, the effective interest rate was 7.0% . The outstanding balance was $2.8 million and $0.0 million as of December 31, 2016 and December 31, 2015, respectively.

10 . Share-Based Compensation

As of December 31, 2016 , we have two share-based compensation plans approved by stockholders: the Sun Communities, Inc. 2015 Equity Incentive Plan (the "2015 Equity Plan") and the First Amended and Restated 2004 Non-Employee Director Option Plan (“Director Plan”). In July 2015, the 2015 Equity Plan replaced the Sun Communities, Inc. 2009 Equity Incentive Plan (the "2009 Equity 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.

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.

Restricted Stock - 2015 Equity Plan

At the Annual Meeting of Stockholders held on July 20, 2015, the stockholders approved the 2015 Equity Plan. The 2015 Equity Plan had been adopted by the Board and was effective upon approval by our stockholders. The maximum number of shares of common stock that may be issued under the 2015 Equity Plan is 1,750,000 shares of our common stock, with 1,542,500 shares remaining for future issuance.

During 2016, we granted 81,000 shares of restricted stock to key employees under the Sun Communities, Inc. 2015 Equity Incentive Plan. The shares had a weighted average fair value of $69.70 per share and generally vest in the following manner: 35% on the third anniversary; 35% on the fourth anniversary; 20% on the fifth anniversary; 5% on the six anniversary; and 5% on the seventh anniversary. The fair values of the issued awards were determined by using the closing price of our common stock on the dates the shares were issued.

The maximum number of options, restricted stock and OP units that may be issued under the Director Plan is 175,000 shares, with 43,474 shares remaining for future issuance.

In March 2016, we granted 16,800 shares of restricted stock to our non-employee directors under our First Amended and Restated 2004 Non-Employee Director Option Plan. The awards vest on March 11, 2018, and had a fair value of $69.45 per share. The fair value was determined by using the closing share price of our common stock on the date the shares were issued.

Stock options generally vest over a three year period from the date of grant and have a maximum term of 10 years . No grants of options were made in 2016, 2015 or 2014. 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, 2016 , consist of 4,500 non-employee director options. There are no employee options outstanding. There was no compensation expense associated with non-vested stock option awards for the years ended December 31, 2016 , and 2015 .

12 . Income Taxes

We have elected to be taxed as a "REIT" pursuant to Section 856(c) of the Internal Revenue Code of 1986 (“Code”), as amended. In order for us to qualify as a REIT, at least 95% of our gross income in any year must be derived from qualifying sources. In addition, a REIT must distribute annually at least 90% of its REIT taxable income (calculated without any deduction for dividends paid and excluding capital gain) to its stockholders and meet other tests.

Qualification as a REIT involves the satisfaction of numerous requirements (on an annual and quarterly basis) established under highly technical and complex Code provisions for which there are limited judicial or administrative interpretations, and involves the determination of various factual matters and circumstances not entirely within our control. In addition, frequent changes occur in the area of REIT taxation, which requires us to continually monitor our tax status. We analyzed the various REIT tests and confirmed that we continued to qualify as a REIT for the year ended December 31, 2016 .

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 as well as U.S. federal income and excise taxes on our undistributed income. In addition, taxable income from non-REIT activities managed through taxable REIT subsidiaries is subject to federal, state and local income taxes. The Company is also subject to local income taxes in Canada as a result of the acquisition of Carefree in 2016. We do not provide for withholding taxes on our undistributed earnings from our Canadian subsidiaries as they are reinvested and will continue to be reinvested indefinitely outside the United States.

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, 2016 , 2015 , and 2014 , distributions paid per share were taxable as follows (unaudited/rounded):

	Years Ended December 31, — 2016		2015		2014
	Amount	Percentage	Amount	Percentage	Amount	Percentage
Ordinary income	$ 0.81	31.2 %	$ 1.08	41.7 %	$ 0.82	31.7 %
Capital gain	0.51	19.6 %	0.78	30.1 %	0.64	24.6 %
Return of capital	1.28	49.2 %	0.74	28.2 %	1.14	43.7 %
Total distributions declared	$ 2.60	100.0 %	$ 2.60	100.0 %	$ 2.60	100.0 %

Our taxable REIT subsidiaries are subject to U.S. federal income taxes as well as state and local income and franchise taxes. In addition, our Canadian subsidiaries are subject to income tax in Canada.

The components of our provision for income taxes attributable to continuing operations for the year ended December 31, 2016 are as follows (amounts in thousands):

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, depreciation and basis differences between tax and U.S. GAAP on our Canadian investments.

The deferred tax assets and liabilities included in the consolidated balance sheets are comprised of the following tax effects of temporary differences (amounts in thousands):

	As of December 31, — 2016		2015
Deferred Tax Assets
Net operating loss carryforwards	$ 30,821		$ 31,096

SHS has U.S. operating loss carryforwards of approximately $85.1 million , or $28.9 million after tax, as of December 31, 2016 . The loss carryforwards will begin to expire in 2021 through 2035 if not offset by future taxable income. In addition, our Canadian subsidiaries have operating loss carryforwards of approximately $8.7 million, or $2.3 million after tax, as of December 31, 2016.

The loss carryforwards will begin to expire in 2031 through 2036 if not offset by future taxable income.

We had no unrecognized tax benefits as of December 31, 2016 and 2015 . We expect no significant increases or decreases in unrecognized tax benefits due to changes in tax positions within one year of December 31, 2016 .

We classify certain state taxes as income taxes for financial reporting purposes. We recorded a provision for state income taxes of approximately $0.4 million for the year ended December 31, 2016 and $0.2 million for each of the years ended December 31, 2015 and 2014.

As previously noted, 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, 2010 and prior. In addition, our Canadian subsidiaries are subject to taxes in Canada and in the province of Ontario. We are no longer subject to examination by the Canadian tax authorities for the tax years ended December 31, 2011 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, 2016 , 2015 and 2014 .

15 . Derivative Instruments and Hedging Activities

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

The following table provides the terms of our interest rate derivative contracts that were in effect as of December 31, 2016 :

Type	Purpose	Effective Date	Maturity Date	Notional (in millions)	Based on	Variable Rate	Cap Rate	Spread	Effective Fixed Rate
Cap	Cap Floating Rate	4/1/2015	4/1/2018	$ 150.1	3 Month LIBOR	2.7240%	9.0000%	—%	N/A
Cap	Cap Floating Rate	10/3/2016	5/1/2023	$ 9.6	3 Month LIBOR	3.5240%	11.0200%	—%	N/A

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

16 . Fair Value of Financial Instruments

Our financial instruments consist primarily of cash and cash equivalents, accounts and notes receivable, accounts payable, derivative instruments, and debt.

ASC Topic 820, "Fair Value Measurements and Disclosures" ("ASC 820"), requires disclosure about how fair value is determined for assets and liabilities and establishes a hierarchy under which these assets and liabilities must be grouped, based on significant levels of observable or unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company's market assumption. This hierarchy requires the use of observable market data when available. These two types of inputs have created the following fair value hierarchy:

Level 1—Quoted unadjusted prices for identical instruments in active markets;

Level 2—Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets; and

Level 3—Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

We utilize fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The following methods and assumptions were used in order to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value:

Derivative Instruments

The derivative instruments held by us are interest rate cap agreements for which quoted market prices are indirectly available. For those derivatives, we use model-derived valuations in which all significant inputs and significant value drivers are observable in active markets provided by brokers or dealers to determine the fair values of derivative instruments on a recurring basis (Level 2). See Note 15, "Derivative Instruments and Hedging Activities."

Installment Notes Receivable on Manufactured Homes

The net carrying value of the installment notes receivable on manufactured homes estimates the fair value as the interest rates in the portfolio are comparable to current prevailing market rates (Level 2). Refer Note 4, "Notes and Other Receivables."

Long Term Debt and Lines of Credit

The fair value of long-term debt (excluding the secured borrowing) is based on the estimates of management and on rates currently quoted, rates currently prevailing for comparable loans, and instruments of comparable maturities (Level 2). Refer to Note 8, "Debt and Lines of Credit."

F - 43

SUN COMMUNITIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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 on the Consolidated Balance Sheets. The net carrying value of the collateralized receivables estimates the fair value as the interest rates in the portfolio are comparable to current prevailing market rates (Level 2). Refer to Note 3, "Collateralized Receivables and Transfers of Financial Assets."

Financial Liabilities

We estimate the fair value of our contingent consideration liability based on discounting of future cash flows using market interest rates and adjusting for non-performance risk over the remaining term of the liability (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.

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, 2016 . The table presents the carrying values and fair values of our financial instruments as of December 31, 2016 and December 31, 2015 that were measured using the valuation techniques described above (in thousands). The table excludes other financial instruments such as cash and cash equivalents, accounts receivable, and accounts payable because the carrying values associated with these instruments approximate fair value since their maturities are less than one year.

Financial assets	December 31, 2016 — Carrying Value	Fair Value	December 31, 2015 — Carrying Value	Fair Value
Installment notes receivable on manufactured homes, net	$ 59,320	$ 59,320	$ 20,418	$ 20,418

17 . Recent Accounting Pronouncements

In January 2017, the FASB issued ASU 2017-1 "Business Combinations (Topic 805): Clarifying the Definition of a Business." This update clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The definition of a business affects many areas of accounting including acquisitions, disposals, goodwill, and consolidation. The guidance will be effective for fiscal years beginning after December 15, 2017, including interim periods within that year, with early application allowed for certain transactions. We are currently evaluating the impact of the adoption of this ASU.

In November 2016, the FASB issued ASU 2016-18 "Statement of Cash Flows (Topic 230): Restricted Cash." This update requires inclusion of restricted cash and restricted cash equivalents with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The guidance will be effective for fiscal years beginning after December 15, 2017, including interim periods within that year. We are currently evaluating the impact of the adoption of this ASU.

In October 2016, the FASB issued ASU 2016-16 "Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory." This update requires that an entity recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. The guidance will be effective for fiscal years beginning after December 15, 2017, including interim periods within that year. We are currently evaluating the impact of the adoption of this ASU.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

In August 2016, the FASB issued ASU 2016-15 "Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments" . This update addresses eight specific cash flow issues with the objective of reducing existing diversity in practice. The guidance will be effective for fiscal years beginning after December 15, 2017, including interim periods within that year. We are currently evaluating the impact of the adoption of this ASU.

In June 2016, the FASB issued ASU 2016-13 "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments" . This update replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The amendments in this update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. We are in the initial phases of evaluating how this guidance will impact our accounting policies regarding assessment of, and allowance for, loan losses. Refer to "Notes and other receivables" in Note 1, "Significant Accounting Policies" for additional information.

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

In February 2016, the FASB issued ASU 2016-02 " Leases (Topic 842). " The core principle of this update is that a lessee should recognize the assets and liabilities that arise from leases while the accounting by a lessor is largely unchanged from that applied under previous GAAP. The amendments in this update are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Our income from real property and rental home revenue streams is derived from rental agreements where we are the lessor. As noted above, the lessor accounting model is largely unchanged by this update. We are the lessee in other arrangements, primarily for our executive offices, ground leases at five communities, and certain equipment. We are currently evaluating our inventory of such leases to determine which will require recognition of right of use assets and corresponding lease liabilities, and the related disclosure requirements thereto.

In April 2015, the FASB issued ASU 2015-03 " Interest - Imputation of Interest (Subtopic 835-30) Simplifying the Presentation of Debt Issuance Costs ". This amendment requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. In August 2015, the FASB issued ASU 2015-15 " Interest - Imputation of Interest (Subtopic 835-30) Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements " ("ASU 2015-15"). ASU 2015-15 provides commentary that the SEC staff would not object to an entity deferring and presenting costs associated with line of credit arrangements as an asset and subsequently amortizing them ratably over the term of the revolving debt arrangement. We adopted these amendments retrospectively for all periods presented as of January 1, 2016. The adoption resulted in reclassifications of deferred financing costs of $8.4 million and $0.3 million from Other assets, net to Mortgage loans payable and Lines of credit, respectively, on the Consolidated Balance Sheets as of December 31, 2015. The debt issuance costs of $0.3 million netted against Lines of credit related to our $58.0 million term loan, whereas $3.3 million of debt issuance costs related to our revolving loan remained classified within Other assets, net on the Consolidated Balance Sheets.

In February 2015, the FASB issued ASU No. 2015-02 " Consolidation (Topic 810) Amendments to the Consolidation Analysis " ("ASU 2015-02") which modified the evaluation of whether limited partnerships and similar legal entities are variable interest entities or voting interest entities. All entities are subject to reevaluation under the revised consolidation model. The Company is the sole general partner in a limited partnership, and as such, the Company has complete control in conducting all business activities associated with the Partnership. Limited partners do not have kick-out rights or participating rights. The Company adopted ASU 2015-02 as of January 1, 2016 and fully consolidates the activities of the Operating Partnership within its Consolidated Financial Statements under the variable interest entity model as it is the primary beneficiary. There was no impact to our Consolidated Financial Statements as we previously consolidated under the voting interest entity model.

In May 2014, the FASB issued ASU 2014-09 " Revenue from Contracts with Customers (Topic 606) " ("ASU 2014-09"). The objective of this amendment is to establish a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will supersede most of the existing revenue recognition guidance, including industry-specific guidance. The core principle is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In applying this amendment, companies will perform a five-step analysis of transactions to determine when and how revenue is recognized. This amendment applies to all contracts with customers except those that are within the scope of other topics in the FASB ASC.

with a cumulative effect of initially applying the amendments recognized at the date of initial application. In July 2015, the FASB issued ASU 2015-14 which deferred the effective date of ASU 2014-09 by one year to annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period.

We anticipate adopting ASU 2014-09 and the related updates subsequently issued by the FASB in January 2018, via the modified retrospective approach. Applicability of the standard updates to our revenue streams and other considerations are summarized below.

Income from real property - is derived from rental agreements whereby we lease land to residents in our communities. We account for these revenues pursuant to ASC 840 "Leases."

Revenue from home sales - is recognized pursuant to ASC 605 "Revenue Recognition," as the manufactured homes are tangible personal property that can be located on any parcel of land. The manufactured homes are not permanent fixtures or improvements to the underlying real estate, and are therefore not considered by us to be subject to the guidance in ASC 360-20 "Real Estate Sales."

Rental home revenue - is comprised of rental agreements whereby we lease homes to residents in our communities. We account for these revenues pursuant to ASC 840 "Leases."

Ancillary revenues - are primarily comprised of restaurant, golf, merchandise and other activities at our RV communities. These revenues are recognized pursuant to ASC 605 "Revenue Recognition," at point of sale to customers as our performance obligations are then satisfied.

Interest income - on our notes receivable will continue to be recognized as revenue, but presented separately from revenue from contracts with customers, as interest income is not in the scope of ASU 2014-09 and the related updates subsequently issued by the FASB.

Broker commissions and other revenues, net - is primarily comprised of (i) brokerage commissions that we account for on a net basis pursuant to ASC 605 "Revenue Recognition," as our performance obligation is to arrange for a third party to transfer a home to a customer; and (ii) notes receivable loss reserves.

As detailed above, our revenues from home sales, ancillary revenues, and broker commissions will be in the scope of the new guidance. While our evaluations are ongoing, we do not expect material changes to our accounting policies for these revenue streams. Upon adoption, we will present contract assets and liabilities, as applicable, when one party to a transaction has performed and the other has not. Further, we will expand our disclosures regarding these revenue streams, as applicable, to discuss our contract balances, performance obligations, significant judgments made, and contract costs.

ALL Acquisition

During the fourth quarter of 2014 and the first quarter of 2015, we purchased a portfolio of 59 MH communities from the Green Courte parties for aggregate consideration of $1.3 billion . In January 2015, we sold 150,000 shares of our common stock and 200,000 Series A-4 preferred OP units for an aggregate purchase price of $12.5 million to one of the Green Courte parties. Randall K. Rowe and James R. Goldman are beneficial owners and directors and officers of certain of the Green Courte parties. Messrs. Rowe and Goldman served on our board of directors from January 2015 through March 2016.

In June 2015, we issued 25,664 shares of common stock and 34,219 shares of Series A-4 Preferred Stock to one of the Green Courte parties in connection with the ALL acquisition. In August 2015, we repurchased from certain of the Green Courte entities and their affiliates an aggregate of 4,066,586 shares of Series A-4 Preferred Stock at a purchase price of $31.08 per share. As part of the aforementioned repurchase, 156,625 shares of Series A-4 Preferred Stock held by Mr. Rowe and his affiliates and 22,577 shares of Series A-4 Preferred Stock held by Mr. Goldman were repurchased. See Note 2, "Real Estate Acquisitions and Dispositions" and Note 9, "Equity and Mezzanine Securities," for additional information regarding these transactions.

20. Subsequent Events

In January 2017, we issued 280,502 shares of common stock under our Sales Agreement at the prevailing market price of our common stock at the time of each sale with a weighted average sales price of $76.47 per share. We received net proceeds totaling $21.2 million . Refer to Note 9, "Equity and Mezzanine Securities," for additional information regarding our Sales Agreement.

In January 2017, we defeased a $18.9 million collateralized term loan with an interest rate of 6.49% that was due to mature on August 1, 2017, releasing one community. As a result of the transaction, we recognized a loss on debt extinguishment of $0.5 million .

Additionally, in February 2017, we repaid a $10.0 million collateralized term loan with an interest rate of 5.57% that was due to mature on May 1, 2017, releasing an additional community. There were no debt extinguishment costs recognized for this transaction.
