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., a Michigan corporation (“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, 2019 , we owned, operated or had an interest in a portfolio of 422 properties in 33 states and Ontario, Canada (collectively, the “Properties” or “Communities”), including 266 MH communities, 122 RV communities, and 34 Properties containing both MH and RV sites. As of December 31, 2019 , the Properties contained an aggregate of 141,293 developed sites comprised of 93,821 developed MH sites, 26,056 annual RV sites (inclusive of both annual and seasonal usage rights), and 21,416 transient RV sites. There are approximately 10,300 additional MH and RV sites suitable for development. We also own a 50 percent interest in a joint venture formed to establish and grow a manufactured housing community development program in Australia.

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 3,146 full and part time employees as of December 31, 2019 .

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 conduct substantially all of 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, 2019 , the Operating Partnership had issued and outstanding:

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

• 309,234 Series A-1 preferred OP units;

• 310,424 Series C preferred OP units;

• 488,958 Series D preferred OP units;

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

• 95,600,640 common OP units.

As of December 31, 2019 , we held:

• no Aspen preferred OP units, Series A-1 preferred OP units, Series C preferred OP units, Series D preferred OP units, or Series A-3 preferred OP units;

• 93,180,481 common OP units, or approximately 97.5 percent of the issued and outstanding common OP units;

In January 2019, we redeemed all 26,750 outstanding Series B-3 preferred OP units. The weighted average redemption price per unit, which included accrued and unpaid distributions, was $100.153424. In the aggregate, we paid $2.7 million to redeem all of the Series B-3 OP units.

In December 2019, we converted all outstanding shares of our 6.50 percent Series A-4 Cumulative Convertible Preferred Stock and Series A-4 preferred OP units into common stock and common OP units, respectively. All 1,031,747 shares of Series A-4 preferred stock were converted into 458,541 shares of common stock (net of fractional shares paid in cash) and all 405,656 Series A-4 preferred OP units were converted into 180,277 common OP units (net of fractional shares paid in cash).

On January 9, 2020, the Operating Partnership created a new class of OP units named Series E Preferred OP Units in conjunction with the acquisition of a MH community in East Falmouth, Massachusetts. As of February 13, 2020, 90,000 Series E Preferred OP Units were outstanding.

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, 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 D preferred OP units;

• next, the Series E 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 (or prior to January 1, 2034 with respect to the extended units discussed below), 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 percent 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

SUN COMMUNITIES, INC.

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. Except for Extended Units as discussed below, each Aspen preferred OP unit is entitled to receive distributions in an amount equal to the product of (x) its original per unit issuance price of $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 percent nor more than 9 percent. On January 2, 2024, (or on January 2, 2034, with respect to the Extended Units described below), 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 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.

On January 13, 2020, at the election of certain Aspen preferred OP unit holders, the Operating Partnership extended the automatic redemption date and reduced the annual distribution rate for 270,000 of the Aspen preferred OP units (the “Extended Units”). The Extended Units may be converted at the holder’s election into common OP units at any time before January 1, 2034 using the same formula as for the other Aspen Units. All Extended Units then outstanding must be redeemed by the Operating Partnership on January 2, 2034 at the same redemption price as for the other Aspen preferred OP units. The Extended Units receive annual distributions at a rate of 3.8 percent on their original $27.00 per unit issuance price. As of February 13, 2020, 270,000 of the Extended Units and 1,013,813 other Aspen preferred OP units were outstanding.

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 percent. 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 percent. 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 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) 4.5 percent until April 1, 2020, and (ii) 5.0 percent 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.

Series D Preferred OP Units

Subject to certain limitations, each Series D preferred OP unit is exchangeable at any time after the first anniversary of its issuance date into 0.8 shares of the Company’s common stock (as such ratio is subject to adjustment for certain capital events). The Series D preferred OP units provide for quarterly distributions on the $100 per unit issue price of 3.75 percent per year until January 31, 2021, and 4.0 percent per year thereafter. Subject to certain limitations, the Series D preferred OP unit holders may cause the Operating Partnership to redeem all or a portion of their Series D preferred OP units for $100 per unit (plus any accrued but unpaid distributions) any time after the earlier of: (i) the fifth anniversary of the issuance of the Series D preferred OP units, or (ii) the Operating Partnership’s notice of the death of the principal of the initial holder of the Series D preferred OP units. The Series D preferred OP units have no voting rights.

SUN COMMUNITIES, INC.

Series E Preferred OP Units

Subject to certain limitations, each Series E Preferred Unit is exchangeable at any time after the first anniversary of its issuance date into that number of shares of the Company’s common stock equal to the quotient obtained by dividing $100.00 by $145.00 (which ratio is subject to adjustment for certain capital events). The Series E Preferred Units provide for quarterly distributions of 5.25 percent per year until the second anniversary of their issuance date and 5.50 percent per year thereafter. The Series E preferred OP units have no voting rights.

REAL PROPERTY OPERATIONS

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

An 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 site within the community. Manufactured homes are available in a wide array of designs, providing owners with a level of customization generally unavailable in multi-family housing developments.

Modern MH communities contain improvements similar to other garden‑style residential developments, including centralized entrances, paved streets, curbs, 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.

An 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.

Renters at our Properties lease the site on which a manufactured home, vacation rental home, or RV is located. We typically 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 eight of our 422 communities, we do not own all of the underlying land and 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.

We compete with other available MH and RV communities, and alternative forms of housing (such as on-site constructed homes, condominiums and townhouses) as they provide housing alternatives to potential tenants of MH and RV communities.

PROPERTY MANAGEMENT

Our property management strategy emphasizes intensive, hands-on management by dedicated, on-site 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, 2019 , we employed 3,146 full and part time employees, of which 2,742 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 MH industry since 1995, three Senior Vice Presidents of Operations and Sales, 10 Divisional Vice Presidents and 36 Regional Vice Presidents. Each Regional Vice President is responsible for regular property inspections, and oversight of property operations and sales functions, semi-annual market surveys of competitive communities, and interaction with local manufactured home dealers for eight to fifteen 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 approximately 350 trainings including books, online courses, webinars, and live sessions for our team members through our Sun University, which has led to increased knowledge and accountability for daily operations and policies and procedures.

SUN COMMUNITIES, INC.

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. Because 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, 2019 , SHS had 11,325 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 46,400 applications during 2019 to live in our Properties, providing a significant “resident boarding” system that allows us to market the purchase of a home to the qualified 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.

Our home sales and leasing operations compete with other local and national MH dealers and MH community 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. 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.

SITE LEASES OR USAGE RIGHTS

Typical tenant leases for MH sites are year-to-year or month-to-month, renewable upon the consent of both parties, or, in some instances, as provided by statute. Certain of our leases, mainly at our Florida and California properties, are tied to the consumer price index or other indices as they relate 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, 2019 , on average 2.2 percent of the homes in our communities have been removed by their owners and 6.5 percent 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 $7,000 . On average, our residents remain in our communities for approximately 12 years, while homes, which give rise to the rental stream, remain 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.

ACQUISITIONS

For the year ended December 31, 2019 , the Company acquired 47 communities, totaling over 10,000 developed sites and over 900 sites available for expansion, for a total purchase price of approximately $ 815.2 million.

SUN COMMUNITIES, INC.

EXPANSION / DEVELOPMENT

For the year ended December 31, 2019 , the Company completed the construction of approximately 1,230 expansion sites in 16 existing communities.

For the year ended December 31, 2019 , the Company completed the construction of approximately 1,100 sites at four ground-up developments and one redevelopment community.

All written and oral forward-looking statements attributable to us or persons acting on our behalf are qualified in their entirety by these cautionary statements.

SUN COMMUNITIES, INC.

ITEM 1A. RISK FACTORS

Our prospects are subject to certain uncertainties and risks. Our future results could differ materially from current results, and our actual results could differ materially from those projected in forward-looking statements as a result of certain risk factors. These risk factors include, but are not limited to, those set forth below, other one-time events, and important factors disclosed previously and from time to time in our other filings with the SEC.

REAL ESTATE AND OPERATIONS RISKS

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, 2019 , 125 properties, representing approximately 31.6 percent of developed sites, are located in Florida; 72 properties, representing approximately 20.2 percent of developed sites, are located in Michigan; 23 properties, representing approximately 6.5 percent of developed sites, are located in Texas; and 31 properties, representing approximately 5.6 percent 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 local economies or other local real estate market conditions which could adversely affect occupancy rates, rental rates, and property values in these markets.

Our revenue 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, including between the U.S. dollar and each of the Canadian dollar and Australian 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 our 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 communities. The number of competitive MH and RV communities 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 RV industries may lead to fluctuations in our operating results .

The RV markets can experience cycles of growth and downturn due to seasonality patterns. In the RV market, certain Properties maintain higher occupancy during the summer months, while 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 selectively acquire MH and RV properties. 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;

• acquired properties may fail to perform as expected;

SUN COMMUNITIES, INC.

• 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 occur, our business and results of operations could be adversely affected.

In addition, we may acquire properties subject to liabilities and we may be left with no, or limited, recourse, with respect to unknown liabilities. As a result, we may have to pay substantial sums to settle any liabilities asserted against us based upon ownership of newly acquired properties, 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.

We engage in the construction and development of new communities or expansion of existing communities and intend to 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 occur, 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 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. 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.

SUN COMMUNITIES, INC.

Legislative requirements can limit accessibility of affordable financing for potential manufactured home buyers.

Legislation impacting third party loan originators, consumer protection laws and lender requirements to investigate a borrower's creditworthiness may restrict access to affordable financing to potential manufactured home buyers.

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 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 the property, to borrow using the property as collateral or to develop the 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 permit 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.

We subject our Properties 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.

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

We rely intensively on information technology to account for tenant transactions, manage the privacy of tenant data, communicate internally and externally, and analyze our financial and operating results. In the ordinary course of our business, we collect and store sensitive data, including our proprietary business information and that of our tenants, clients, vendors and employees in our facilities and on our network. In addition, we engage third party service providers that may have access to such information in connection with providing necessary information technology and security and other business services to us. This information may include personally identifiable information such as social security numbers, banking information and credit card information.

We address potential breaches or disclosure of this confidential information by implementing a variety of security measures intended to protect the confidentiality and security of this information including (among others) engaging reputable, recognized firms to help us design and maintain our information technology and data security systems, including testing and verification of their proper and secure operations on a periodic basis. We also maintain cyber risk insurance to provide some coverage for certain risks arising out of data and network breaches.

Despite our security measures, our information technology and infrastructure, as well as that of our third-party vendors, may be vulnerable to attacks by hackers (including through malware, ransomware, computer viruses, and email phishing schemes) or breached due to employee error, malfeasance, fire, flood or other physical event, or other disruptions. Any such breach or disruption could compromise our or a third-party vendor’s 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, including our ability to service our tenants and our ability to analyze and report our financial and operating results,

• decrease our revenues,

• damage our reputation,

• cause a loss of confidence,

• increase our insurance premiums, or

• have other material adverse effects on our business.

SUN COMMUNITIES, INC.

We are dependent on continuous access to the internet to use our cloud-based applications. Damage to, or failure of our information technology systems, including as a result of any of the reasons described above, could adversely affect our results of operations as we may incur significant costs or data loss. We continually assess new and enhanced information technology solutions to manage the risk of system failure or interruption.

Expanding social media platforms present new challenges.

Social media outlets continue to grow and expand, which presents us with new risks. Adverse content about us and our Properties on social media platforms could result in damage to our reputation or brand. Improper posts by employees or others could result in disclosure of confidential or proprietary information regarding our operations.

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

We have a significant concentration of properties in Florida and California, where natural disasters or other catastrophic events such as hurricanes, earthquakes, floods and wildfires could negatively impact our operating results and cash flows. 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. We believe the policy specifications and insured limits are appropriate and adequate given the relative risk of loss, the cost of the coverage and industry practice. However, 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. We would also continue to be obligated to repay any mortgage indebtedness or other obligations related to the community. If an uninsured liability to a third party were to occur, we would incur the cost of defense and settlement with, or court ordered damages to, that third party. A significant uninsured property or liability loss could have a material adverse effect on our business and our financial condition and results of operations.

Investments through joint ventures involve risks not present for Properties in which we are the sole owner.

We have invested and may continue to invest as a joint venture partner in joint ventures. These investments involve risks, including, but not limited to, the possibility the other joint venture partner may have business goals which are inconsistent with ours, possess the ability to take or force action or withhold consent contrary to our requests, fail to provide capital or fulfill its obligations, or become insolvent and require us to assume and fulfill the joint venture’s financial obligations. Conflicts arising between us and our joint venture partners may be difficult to manage or resolve and it could be difficult to manage or otherwise monitor the existing business arrangements. We and our joint venture partners may each have the right to initiate a buy-sell arrangement, which could cause us to sell our interest, or acquire a joint venture partner’s interest, at a time when we otherwise would not have entered into such a transaction. Each joint venture agreement is individually negotiated, and our ability to operate, finance, or dispose of a Property in our sole discretion may be limited to varying degrees depending on the terms of the applicable joint venture agreement.

Climate change may adversely affect our business.

To the extent that significant changes in the climate occur in areas where our Properties are located, we may experience extreme weather and changes in precipitation and temperature, all of which may result in physical damage to or a decrease in demand for properties located in these areas or affected by these conditions. Should the impact of climate change be material in nature, including significant property damage to or destruction of our Properties, or occur for lengthy periods of time, our financial condition or results of operations may be adversely affected. In addition, changes in federal, state and local legislation and regulation based on concerns about climate change could result in increased capital expenditures on our Properties (for example, to improve their energy efficiency and/or resistance to inclement weather) without a corresponding increase in revenue, resulting in adverse impacts to our net income.

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, 2019 , we had approximately $3.4 billion of total debt outstanding, consisting of approximately $3.2 billion in debt that is collateralized by mortgage liens on 188 of the Properties, $183.9 million on our lines of credit, $35.2 million of mandatorily redeemable interest, and $34.7 million that is preferred OP units - mandatorily redeemable. 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.

SUN COMMUNITIES, INC.

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

• our cash flow may be insufficient to meet required debt payments, or we may need to dedicate a substantial portion of our cash flow to pay 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 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;

• 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.

The phase out of the London Interbank Offered Rate (LIBOR), or the replacement of LIBOR with a different reference rate, may adversely affect interest rates.

On July 27, 2017, the Financial Conduct Authority (the authority that regulates LIBOR) announced that it would phase out LIBOR by the end of 2021. Many of our Property-level real estate loans have fixed interest rates which will not be impacted by any change in LIBOR. Certain of our other loans, including a majority of the borrowings under our $750.0 million senior credit facility, have interest rates based on LIBOR. Our senior credit facility provides that we and the administrative agent for the lenders will negotiate an interest rate to replace the current LIBOR-based rate, and if the parties do not negotiate a replacement interest rate, the new rate will be based on the prime rate. The replacement of LIBOR with an alternative rate or benchmark may adversely affect our interest rates and result in higher borrowing costs. This could materially and adversely affect our results of operations, cash flows and liquidity.

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 qualify as a REIT. 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. 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.

SUN COMMUNITIES, INC.

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.

The Tax Cut and Jobs Act (the “Tax Act”) was enacted into law in December 2017. The overall impact of the Tax Act is uncertain. In addition, there are a significant number of technical issues clarified with respect to the interpretation and application of the Tax Act which may or may not be clarified by future guidance. It is not possible to predict whether such clarifications will result in adverse consequences to the Company or its stockholders. Stockholders are urged to consult their tax advisors with respect to the effects of the Tax Act and any other potential amendments to relevant tax laws.

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 percent 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 percent test are similar in most respects. Qualifying income for the 90 percent 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 percent 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.

Partnership tax audit rules could have a material adverse effect on us.

The Bipartisan Budget Act of 2015 changed the rules applicable to U.S. federal income tax audits of partnerships. Under the rules, effective for taxable years beginning in 2018, among other changes and subject to certain exceptions, any audit adjustment to items of income, gain, loss, deduction, or credit of a partnership (and a partner’s allocable share thereof) is determined, and taxes, interest, and penalties attributable thereto are assessed and collected, at the partnership level. Unless the partnership makes an election permitted under the new law or takes certain steps to require the partners to pay their tax on their allocable shares of the adjustment, it is possible that partnerships in which we directly or indirectly invest, including the Operating Partnership, would be required to pay additional taxes, interest and penalties as a result of an audit adjustment. We, as a direct or indirect partner of the Operating Partnership and other partnerships, could be required to bear the economic burden of those taxes, interest, and penalties even though the Company, as a REIT, may not otherwise have been required to pay additional corporate-level tax. The changes created by these rules are significant for collecting tax in partnership audits and, accordingly, there can be no assurance that these rules will not have a material adverse effect on us.

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 percent 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 percent 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 percent 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. This would result in unexpected tax liability which would adversely affect our cash flows.

SUN COMMUNITIES, INC.

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 percent. Dividends payable by REITs, however, are generally not eligible for this reduced rate, although the new Tax Act permits a 20 percent deduction equal to the amount of qualifying REIT dividends received, thus bringing the maximum federal tax rate on qualifying REIT dividends to 29.6 percent. While 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.

Prospective investors should consult their own tax advisors regarding the effect of this change on their effective tax rate with respect to REIT dividends.

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 percent 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 an equity interest of approximately 28.1 percent 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 103,100 rentable square feet of permanent space. The initial term of the lease is until October 31, 2026, and the average gross base rent is $18.95 per square foot until October 31, 2020 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.

Legal Counsel. During 2017- 2019 , Jaffe, Raitt, Heuer, & Weiss, Professional Corporation acted as our general counsel and represented us in various matters. Arthur A. Weiss is the Chairman of the Board of Directors and a shareholder of such firm. We incurred legal fees and expenses owed to Jaffe, Raitt, Heuer, & Weiss of approximately $11.1 million , $7.1 million and $5 million in the years ended December 31, 2019 , 2018 and 2017 , respectively.

Use of Airplane. Gary A. Shiffman is the beneficial owner of an airplane that we use from time to time for business purposes. During the year ended December 31, 2019, we paid $0.4 million for the use of the airplane. Mr. Shiffman may have a conflict of interest with respect to his obligations as our officer and director and his ownership interest in the airplane.

Telephone Services. Brian M. Hermelin is a principal and a beneficial owner of an entity that installs and maintains emergency telephone systems at our Properties. During the year ended December 31, 2019, we paid $0.2 million for these services. Mr. Hermelin may have a conflict of interest with respect to his obligations as our director and his position with and ownership interest in the provider of these services.

SUN COMMUNITIES, INC.

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 than 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 percent Ownership Limit. In order to qualify and maintain our qualification as a REIT, not more than 50 percent 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 percent, 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 percent 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: (a) deter tender offers for the common stock, which offers may be advantageous to stockholders; and (b) 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 percent 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, none of which is currently outstanding, 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. 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.

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 percent 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 percent 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.

SUN COMMUNITIES, INC.

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 into 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 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.

Our Board of Directors has power to adopt, alter or repeal any provision of our bylaws or make new bylaws, provided, however, that our stockholders may alter or repeal any provision of our bylaws and adopt new bylaws if any such alteration, repeal or adoption is approved by the affirmative vote of a majority of all votes entitled to be cast on the matter.

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 or issuances of our common or preferred 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 13, 2020, in the future we may issue to the limited partners of the Operating Partnership, up to approximately 4.4 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 13, 2020, options to purchase 1,500 shares of our common stock were outstanding under our equity incentive plans, and we currently have the authority to issue restricted stock awards or options to purchase up to an additional 1,041,758 shares of our common stock pursuant to our equity incentive plans. In addition, we entered into an At-the-Market Offering Sales Agreement in July 2017 to issue and sell shares of common stock. As of February 13, 2020, our Board of Directors had authorized us to sell an additional $286.3 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.

SUN COMMUNITIES, INC.

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

Our current and future investments in and operations of Canadian and Australian properties are or will be exposed to the effects of changes in the Canadian dollar and Australian dollar, respectively, 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, uncertain tax and economic plans in the U.S. executive and legislative branches, 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 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, 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: (a) its net earnings for the fiscal year in which the distribution is made; (b) its net earnings for the preceding fiscal year; or (c) 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, if any, 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.

SUN COMMUNITIES, INC.

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 New York Stock Exchange (“NYSE”), on which we list our common 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;

• 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 and preferred stock to demand a higher dividend yield;

• changes in foreign currency exchange rates, including between the U.S. dollar and each of the Canadian dollar and the Australian dollar;

• changes in market valuations of similar companies;

• adverse market reaction to the amount of our debt outstanding at any time, the amount of our debt maturing in the near-term 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.

ITEM 2. PROPERTIES

As of December 31, 2019 , the Properties were located throughout the US and in Ontario, Canada and consisted of 266 MH communities, 122 RV communities, and 34 properties containing both MH and RV sites. As of December 31, 2019 , the Properties contained an aggregate of 141,293 developed sites comprised of 93,821 developed manufactured home sites, 26,056 annual RV sites (inclusive of both annual and seasonal usage rights), and 21,416 transient RV sites. There are approximately 10,300 additional MH and RV sites suitable for development. Most of the Properties include amenities oriented toward family and retirement living. Of the 422 Properties, 194 each have more than 300 developed sites, with the largest having 2,341 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, 2019 , the Properties had an occupancy rate of 96.4 percent excluding transient RV sites. Since January 1, 2019, the Properties have averaged an aggregate annual turnover of homes (where the home is moved out of the community) of approximately 2.8 percent 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 7.0 percent . The average renewal rate for residents in our Rental Program was 63.2 percent for the year ended December 31, 2019 .

We believe that our Properties’ high amenity levels, customer service loyalty, and customer retention program 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 courts, 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.

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

The following tables set forth certain information relating to the Properties as of December 31, 2019 . The occupancy percentage includes MH sites and annual RV sites and excludes transient RV sites.

(1) Occupancy in these Properties reflects the fact that these communities are in a lease-up phase following an expansion, redevelopment or initial construction.

(2) Occupancy percentage excludes transient RV sites. Percentage calculated by dividing revenue producing sites by developed sites. A revenue producing site is defined as a site that is occupied by a paying resident or reserved by a customer with annual or seasonal usage rights. A developed site is defined as an adequate sized parcel of land that has road and utility access which is zoned and licensed (if required) for use as a home site.

(3) We have an ownership interest in Sunset Beach, Strafford, and Chincoteague Island, but do not maintain and operate the property.

(4) Occupancy in these Properties at 12/31/2019 reflects redevelopment following asset impairments resulting from Hurricane Irma in September 2017.

(5) No occupancy in 2018 as communities were acquired in 2019.

Market Information

Our common stock has been listed on the NYSE since December 8, 1993, and traded under the symbol “SUI”. On February 13, 2020, the closing share price of our common stock was 165.97 per share on the NYSE, and there were 283 holders of record for the 93,319,200 outstanding shares of common stock.

On February 13, 2020, the following OP units of the Operating Partnership were outstanding:

See “Structure of the Company” under Part I, Item 1 of this Annual Report on Form 10-K.

The decision to declare and pay distributions on shares of our common stock and common OP units 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, general overall economic conditions, and other factors.

Property Operations

Occupancy in our Properties, as well as our ability to increase rental rates, directly affect 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. We continue to sell homes at a high level in our communities and expect this trend to continue.

(2) Contains 31 communities located in CT, GA, MD, NH, NJ, NY, NC and SC. In conjunction with the acquisition, we issued 1,972,876 shares of common stock, net of fractional shares paid in cash.

(3) Contains 201 MH sites and 301 RV sites.

(4) Contains two MH communities.

(5) In conjunction with the acquisition, we issued Series D Preferred OP units. As of December 31, 2019, 488,958 Series D Preferred OP units were outstanding.

Construction Activity

Ground-up Developments - During the year ended December 31, 2019 , we constructed nearly 1,100 sites at four ground-up development communities and one re-development located in Colorado, Florida, North Carolina and South Carolina. We expect to construct 550 - 750 sites in 2020.

Expansions - We have been focused on expansion opportunities adjacent to our existing communities, and we have developed over 4,600 sites within the past three years. We have expanded approximately 1,230 sites at 16 communities in 2019 . We continue to expand our Properties utilizing our inventory of owned and entitled land (approximately 10,300 sites available for development in 84 communities) and expect to construct 1,000 - 1,200 additional expansion sites in 2020.

Markets

Our Properties are largely concentrated in Florida, Michigan, Texas and California. We have expanded our market share in multiple states through recent acquisitions and increased our property holdings in high growth areas of the U.S. including retirement and vacation destinations.

We have also experienced strong revenue growth through recent acquisitions of RV communities. 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 and millennials.

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 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 is a non-GAAP financial measure that we believe is helpful to investors as a supplemental measure of operating performance because it is an indicator of the return on property investment and provides a method of comparing property performance over time. We use NOI as a key measure 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 our properties rather than of the Company overall.

We believe that GAAP net income (loss) is the most directly comparable measure to NOI. NOI should not be considered to be an alternative to GAAP net income (loss) as an indication of our financial performance or GAAP cash flow from operating activities as a measure of our liquidity; nor is it indicative of funds available for our cash needs, including our ability to make cash distributions. Because of the inclusion of items such as interest, depreciation, and amortization, the use of GAAP 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.

FFO is defined by the National Association of Real Estate Investment Trusts (“NAREIT”) as GAAP net income (loss), excluding gains (or losses) from sales of depreciable operating property, plus real estate-related depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures. FFO is a non-GAAP financial measure that management believes is a useful supplemental measure of our operating performance. 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 GAAP net income (loss). Management believes 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. We also use FFO excluding certain gain and loss items that management considers unrelated to the operational and financial performance of our core business (“Core FFO”). We believe that Core FFO provides enhanced comparability for investor evaluations of period-over-period results.

We believe that GAAP net income (loss) is the most directly comparable measure to FFO. The principal limitation of FFO is that it does not replace GAAP net income (loss) as a performance measure or GAAP cash flow from operations as a liquidity measure. Because FFO excludes significant economic components of GAAP net income (loss) including depreciation and amortization, FFO should be used as a supplement to GAAP net income (loss) and not as an alternative to it. Further, 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 is calculated in accordance with our interpretation of standards established by NAREIT, which may not be comparable to FFO reported by other REITs that interpret the NAREIT definition differently.

RESULTS OF OPERATIONS

We report operating results under two segments: Real Property Operations and Home Sales and Rentals. The Real Property Operations segment owns, operates, develops, or has an interest in, a portfolio of MH and RV communities throughout the U.S. and in Canada, and is in the business of acquiring, operating, and expanding MH and RV communities. The Home Sales and Rentals segment offers MH and RV park model sales and leasing services to tenants and prospective tenants of our communities. We evaluate segment operating performance based on NOI and gross profit. Refer to Note 12 , “Segment Reporting,” in our accompanying Consolidated Financial Statements for additional information.

Real Property Operations - Same Communities

A key management tool used when evaluating performance and growth of our properties is a comparison of Same Communities. The Same Community data may change from time-to-time depending on acquisitions, dispositions, management discretion, significant transactions, or unique situations. 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.

(1) The Company adopted ASC 842, the new lease accounting standard, as of January 1, 2019 which required the reclassification of bad debt expense from Property operating expense to Income from real property. To assist with comparability within Same Community results, bad debt expense has been reclassified to be shown as a reduction of Income from real property for all periods presented.

(2) For the comparative periods December 31, 2019 and 2018, the year ended 2018 excludes $0.7 million of expenses incurred for recently acquired properties to bring the properties up to our operating standards. For the comparative periods December 31, 2018 and 2017, the year ended 2017 excludes $2.6 million of expenses incurred for recently acquired properties to bring the properties up to our operating standards. These costs did not meet the Company’s capitalization policy.

(3) The occupancy percentages include MH and annual RV sites and exclude recently completed but vacant expansion sites and transient RV sites.

(4) The occupancy percentages for 2018 and 2017 have been adjusted to reflect incremental growth period-over-period from filled MH expansion sites and the conversion of transient RV sites to annual RV sites.

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

Year ended December 31, 2019 and 2018

The Same Community data includes all properties which we have owned and operated continuously since January 1, 2018 , exclusive of properties under construction. The amounts in the table above reflect constant currency for comparative purposes. Canadian currency figures included within the year ended December 31, 2018 have been translated at 2019 average exchange rates. We have reclassified $ 34.7 million and $ 32.7 million for the years ended December 31, 2019 and 2018 , respectively, to reflect the utility expenses associated with our Same Community portfolio net of recovery.

The 7.3 percent growth in NOI is primarily due to increased Income from real property of $ 47.1 million, or 6.2 percent. The 6.2 percent increase is primarily attributable to a 2.2 percent increase in MH & RV blended occupancy and a 4.5 percent increase in total monthly base rent per site when compared to 2018 . The increase in Income from real property was partially offset by a $ 9.2 million, or 3.8 percent, increase in Property operating expenses, primarily attributable to increases in payroll and benefits, supplies and repairs and real estate taxes.

Year ended December 31, 2018 and 2017

The Same Community data includes all properties which we have owned and operated continuously since January 1, 2017 , exclusive of properties under construction. The amounts in the table above reflect constant currency for comparative purposes. Canadian currency figures included within the year ended December 31, 2017 have been translated at 2018 average exchange rates. We have reclassified $ 32.2 million and $ 30.6 million for the years ended December 31, 2018 and 2017 , respectively, to reflect the utility expenses associated with our Same Community portfolio net of recovery.

The 7.1 percent growth in NOI is primarily due to a 6.4 percent increase in Income from real property. The 6.4 percent increase in Income from real property is primarily due to a 2.2 percent increase in MH & RV blended occupancy and a 4.1 percent increase in total monthly base rent per site. The increase in Income from real property was partially offset by a 4.8 percent increase in Property operating expenses compared to 2017 , which was primarily due to higher utilities, real estate taxes, and legal, taxes, and insurance in 2018 .

(1) In January 2018, we adopted ASU 2017-01. Under previous guidance, substantially all of our property acquisitions were accounted for as business combinations with acquisition related costs expensed as incurred and reported as Transaction costs. Under ASU 2017-01, direct acquisition related costs are capitalized as part of the purchase price. Acquisitions costs that do not meet the criteria for capitalization are expensed as incurred.

(2) These costs represent the expenses incurred to bring recently acquired properties up to our operating standards, including items such as tree trimming and painting costs that do not meet our capitalization policy.

(3) During 2018, the adjustment was for the previously estimated FFO impact of the income related to the loss of earnings in excess of the applicable business interruption deductible in relation to our Florida Keys communities, impaired by Hurricane Irma, that was not recognized as income in those respective periods. The income related to the loss of earnings was recognized during the three months ended December 31, 2018 upon notification of payment by the insurance company. During 2017, the adjustment represented the related estimated loss of earnings in excess of the applicable business interruption deductible.

(4) Other adjustments include early retirement compensation expense, ground lease intangible write-off, and deferred tax benefits.

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

SUN COMMUNITIES, INC.

LIQUIDITY AND CAPITAL RESOURCES

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

Subject to market conditions, we intend to continue to identify opportunities to expand our development pipeline and acquire existing communities. We finance acquisitions through available cash, secured financing, draws on our lines of credit, the assumption of existing debt on properties, and the issuance of equity securities. We will continue to evaluate acquisition opportunities that meet our criteria. Refer to Note 3 , “ Real Estate Acquisitions ” in our accompanying Consolidated Financial Statements for information regarding recent community acquisitions.

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 lines of credit, and the use of debt and equity offerings under our shelf registration statement. Refer to Note 9 , “ Debt and Lines of Credit ” and Note 10 , “ Equity and Temporary Equity ” in our accompanying Consolidated Financial Statements for additional information.

Capital Expenditures

Our capital expenditures include expansion sites and development construction costs, lot modifications, recurring capital expenditures and rental home purchases.

For the years ended December 31, 2019 and 2018 , expansion and development activities of $281.8 million and $152.7 million , respectively, related to costs consisting primarily of construction of sites and other costs necessary to complete home site improvements. The increase is primarily driven by the ground-up developments and redevelopment at five communities.

For the years ended December 31, 2019 and 2018 , lot modification expenditures were $31.1 million and $22.9 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, 2019 and 2018 , recurring capital expenditures were $30.4 million and $24.3 million , respectively, related to our continued commitment to the upkeep of our properties.

We invest in the acquisition of homes intended for the Rental Program. Expenditures for these investments depend upon the condition of the markets for repossessions and new home sales, as well as rental homes. We finance certain of our 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.

Through December 31, 2019 , we have sold shares of our common stock for gross proceeds of $163.8 million under the Sales Agreement. Refer to Note 10 , “ Equity and Temporary Equity ” in our accompanying Consolidated Financial Statements for additional information.

In October 2019, we assumed a term loan facility with Citibank N.A. (“Citibank”), in the amount of $58.0 million. The term loan has a four-year term ending October 29, 2023, and bears interest at a floating rate based on the Eurodollar rate or Prime rate. The outstanding balance was $57.0 million at December 31, 2019.

In May 2019, we amended and restated our credit agreement with Citibank, N.A. and certain other lenders. Pursuant to the credit agreement, we entered into a senior credit facility with Citibank and certain other lenders in the amount of $750.0 million, comprised of a $650.0 million revolving loan, with the ability to use up to $100.0 million for advances in Australian dollars, and a $100.0 million term loan (the “A&R Facility”). We have until March 17, 2020 to draw on the term loan. As of December 31, 2019 , we had not drawn any funds on the term loan. The credit agreement has a four-year term ending May 21, 2023, which can be extended for two additional six-month periods, 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 $350.0 million. If additional borrowings are made pursuant to any such additional commitments, the aggregate borrowing limit under the A&R Facility may be increased up to $1.1 billion.

The A&R Facility bears interest at a floating rate based on the Eurodollar rate or Bank Bill Swap Bid Rate plus a margin that is determined based on our leverage ratio calculated in accordance with the credit agreement, which margin can range from 1.20 percent to 2.10 percent for the revolving loan and 1.20 percent to 2.05 percent for the term loan. As of December 31, 2019 , the margin based on our leverage ratio was 1.20 percent on the revolving loan and 1.20 percent on the term loan. We had $123.6 million and zero of borrowings on the revolving loan and the term loan, respectively, as of December 31, 2019 .

The A&R 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, 2019 and December 31, 2018 , approximately $2.8 million and $3.9 million of availability was used to back standby letters of credit.

Pursuant to the terms of the A&R 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 A&R Facility are as follows:

Covenant	Requirement	As of December 31, 2019
Maximum Leverage Ratio	<65.0%	26.8%
Minimum Fixed Charge Coverage Ratio	>1.40	3.52
Minimum Tangible Net Worth	>$3,257,121	$5,633,050
Maximum Dividend Payout Ratio	<95.0%	58.0%

SUN COMMUNITIES, INC.

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, 2019 , we had 234 unencumbered properties, of which 65 support the borrowing base for our $650.0 million revolving loan in our A&R Facility and 31 support the borrowing base for a term loan facility.

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 of 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.

As of December 31, 2019 , our net debt to enterprise value was approximately 19.0 percent (assuming conversion of all common OP units, Series A-1 preferred OP units, Series A-3 preferred OP units, Series C preferred OP units and Series D preferred OP units to shares of common stock). Our debt has a weighted average maturity of approximately 11.1 years and a weighted average interest rate of 4.0 percent .

Off-Balance Sheet Arrangements

Our off-balance sheet investments include nonconsolidated affiliates. These investments all have varying ownership structures. Substantially all of our nonconsolidated affiliates are accounted for under the equity method of accounting as we have the ability to exercise significant influence, but not control, over the operating and financial decisions of these joint venture arrangements. Refer to Note 7 ," Investments in Nonconsolidated Affiliates " and Note 9 , " Debt and Lines of Credit " in the accompanying consolidated financial statements, for additional information on our off-balance sheet investments.

Nonconsolidated Affiliate Indebtedness - During September 2019, GTSC, LLC entered into a warehouse line of credit with a maximum loan amount of $125.0 million. As of December 31, 2019 , the aggregate carrying amount of debt, including both our and our partners’ share, incurred by GTSC was approximately $123.4 million (of which our proportionate share is approximately $49.4 million). The debt bears interest at a variable rate based on LIBOR plus 1.65 percent per annum and matures on September 15, 2023. Refer to Note 7 ," Investments in Nonconsolidated Affiliates " for additional information on our nonconsolidated affiliates.

(1) Contractual cash obligations in this table exclude debt premiums, discounts and deferred financing costs, as applicable.

(2) Our contractual cash obligations related to interest expense are calculated based on the current debt levels, rates and maturities as of December 31, 2019 (including finance leases), and actual payments required in future periods may be different than the amounts included above. Perpetual securities include one year of interest expense in the “After 5 years” category.

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.

Refer to Note 1 , “ Significant Accounting Policies ,” in our accompanying Consolidated Financial Statements for information regarding our critical accounting estimates.

Impact of New Accounting Standards

Refer to Note 17 , “ Recent Accounting Pronouncements ,” in our accompanying Consolidated Financial Statements for information regarding new accounting pronouncements.

Off-Balance Sheet Arrangements

Nonconsolidated Affiliate Indebtedness - During September 2019, GTSC entered into a warehouse line of credit with a maximum loan amount of $125.0 million. As of December 31, 2019 , the aggregate carrying amount of debt, including both our and our partners’ share, incurred by GTSC was approximately $123.4 million (of which our proportionate share is approximately $49.4 million). The debt bears interest at a variable rate based on LIBOR plus 1.65 percent per annum and matures on September 15, 2023.

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.

Our variable rate debt totaled $183.9 million and $128.0 million as of December 31, 2019 and 2018 , respectively, and bears interest based on Prime or various LIBOR rates. If Prime or LIBOR increased or decreased by 1.0 percent, our interest expense would have increased or decreased by approximately $2.6 million and $2.4 million for the years ended December 31, 2019 and 2018 , respectively, based on the $259.4 million and $235.9 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, and our Australian equity investment and joint venture 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.

At December 31, 2019 and 2018 , our stockholder’s equity included $202.5 million and $141.4 million from our Canadian subsidiaries and Australian equity investments, respectively, which represented 5.2 percent and 4.6 percent of total equity, respectively. Based on our sensitivity analysis, a 10.0 percent strengthening of the U.S. dollar against the Canadian and Australian dollars would have caused a reduction of $20.2 million and $14.1 million to our total stockholder’s equity at December 31, 2019 and 2018 , respectively.

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, 2019 . Based upon this evaluation, our CEO and CFO concluded that our disclosure controls and procedures were effective as of December 31, 2019 .

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, 2019 , 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, 2019 . Based on management’s assessment, we have concluded that our internal control over financial reporting was effective at December 31, 2019 .

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 were no material changes in our internal control over financial reporting during the year ended December 31, 2019 .

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders

Sun Communities, Inc.

Opinion on the financial statements

We have audited the accompanying consolidated balance sheets of Sun Communities, Inc. (a Maryland corporation) and subsidiaries (the “Company”) as of December 31, 2019 and 2018, 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, 2019, and the related notes and financial statement schedule included under Item 15(a) (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2019 and 2018, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2019, in conformity with accounting principles generally accepted in the United States of America.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the Company’s internal control over financial reporting as of December 31, 2019, 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 20, 2020 expressed an unqualified opinion.

Change in accounting principle

As discussed in Note 17 to the consolidated financial statements, the Company has changed its method of accounting for leases in 2019 due to the adoption of ASC Topic 842, Leases.

Basis for opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical audit matters

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Accounting for Acquisitions

The Company's strategy includes growth by acquisition. As described in footnote 3, during 2019, the Company completed forty-four community acquisitions for total consideration of $854 million. The principal considerations for our determination that the accounting for acquisitions is a critical audit matter is that it involves a high degree of subjectivity in evaluating the reasonableness of management's estimates and related assumptions related to the accounting for the recognition of the fair value of assets acquired and liabilities assumed. We performed the following procedures, among others, in connection with forming our overall opinion on the financial statements. We tested management’s controls over the accounting for acquisitions, such as controls over the recognition and measurement of assets acquired, liabilities assumed, and consideration paid. For each of the acquisitions, we read the purchase agreements, evaluated the significant assumptions and methods used in developing the fair value estimates and tested the recognition of the assets acquired and liabilities assumed at fair value.

More specifically, for each acquisition, we assessed, through the use of our internal valuation specialist, whether (1) the values assigned to the tangible assets appeared reasonable based on a cost or market approach for similar properties in each geographic area, (2) intangible assets were properly considered and identified, and (3) the significant assumptions used in valuing the assets and liabilities were reasonable

and (4) if applicable, the value assigned to and accounting for, equity interests in the Company or its subsidiaries that was issued as consideration in the transaction.

As described in footnote 10, the purchase consideration for the acquisition of Country Village Estate also reflected, in part, the estimated fair value of preferred equity interests. In testing the valuation of the equity interests, we considered management’s estimated amount that would be paid upon the ultimate redemption of the securities and the discount rate. We also evaluated management's classification of the equity consideration as either debt, temporary equity or equity on the consolidated balance sheet based on the characteristics of the equity instrument.

Impairment of Investment Properties

As described in footnote 1, the Company reviews the carrying value of investment properties on a quarterly basis or whenever events or changes in circumstances indicate a possible impairment. Events or circumstances that may prompt a review of the carrying value of investment properties may include a significant decrease in the anticipated market price of the investment property, an adverse change to the extent or manner in which an asset may be used, or a significant change in its physical condition or damage due to catastrophic event.

The Company reviews its investment properties for potential impairment through an analysis of net operating income trends period over period. In the event that any impairment indicators are present, the Company undertakes additional analyses utilizing expected undiscounted future cash flows and expected disposition proceeds for a given asset. Forecasting of cash flows requires management to make estimates and assumptions about such variables as the anticipated holding period, rental revenues and operating expenses during the holding period, capital expenditures and rates of return.

In 2019, the Company’s net operating income trend analysis resulted in 10 properties requiring additional analysis. No impairments were identified as a result of the quarterly analysis nor events occurring in 2019.

The principal consideration for our determination that the impairment of investment properties is a critical audit matter is that it involves a high degree of subjectivity in evaluating management's estimates used in determining the undiscounted cash flow estimates. We performed the following procedures, among others, in connection with forming our overall opinion on the financial statements. We tested management’s internal controls over the identification of potential investment property impairments, such as controls over the Company’s quarterly analysis of net operating income trends, as well management review controls to identify potential events which could indicate impairment We examine and evaluate the Company’s net operating income trend analysis and its assessment of other events, and if additional analysis is necessary, we evaluated the significant assumptions and methods used in developing the undiscounted cash flow estimates.

More specifically, when the net operating income analysis indicated that additional analysis was required, we assessed whether the significant assumptions, including estimated holding period, rental revenues and operating expenses during the holding period, capital expenditures and rates of return used in determining the future undiscounted cash flows were reasonable.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders

Sun Communities, Inc.

Opinion on internal control over financial reporting

We have audited the internal control over financial reporting of Sun Communities, Inc. (a Maryland corporation) and subsidiaries (the “Company”) as of December 31, 2019, based on criteria established in the 2013 Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2019, 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) (“PCAOB”), the consolidated financial statements of the Company as of and for the year ended December 31, 2019, and our report dated February 20, 2020 expressed an unqualified opinion on those financial statements.

Basis for opinion

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 are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. 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.

Definition and limitations of internal control over financial reporting

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.

1 . Significant Accounting Policies

Business

Sun Communities, I nc., 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., a Michigan corporation (“SHS”) are referred to herein as the “Company,” “us,” “we,” and “our”. We are a fully integrated, self-administered and self-managed real estate investment trust (“REIT”).

We own, operate, or have an interest in a portfolio, and develop manufactured housing (“MH”) and recreational vehicle (“RV”) communities throughout the United States (“U.S.”). As of December 31, 2019 , we owned, operated or had an interest in a portfolio of 422 developed properties located in 33 states and Ontario, Canada (collectively the “Properties”), including 266 MH communities, 122 RV communities, and 34 communities containing both MH and RV sites. As of December 31, 2019 , the Properties contained an aggregate of 141,293 developed sites comprised of 93,821 developed MH sites, 26,056 annual RV sites, and 21,416 transient RV sites. There are approximately 10,300 additional MH and RV sites suitable for development.

Principles of Consolidation

We consolidate our majority-owned subsidiaries in which we have the ability to control the operations of our subsidiaries and all variable interest entities with respect to which we are the primary beneficiary. We also consolidate entities in which we have a direct or indirect controlling or voting interest. All significant inter-company transactions have been eliminated. 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.

Certain prior period amounts have been reclassified on our Consolidated Financial Statements to conform with current year presentation.

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.

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.

SUN COMMUNITIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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.

On January 1, 2018, we adopted Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) 2017-01, “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. Upon adoption of this standard, substantially all of our property acquisitions are accounted for as asset acquisitions. We allocate the purchase price of these properties on a relative fair value basis and capitalize direct acquisition related costs as part of the purchase price. Acquisition costs that do not meet the criteria to be capitalized are expensed as incurred and presented as General and administrative costs in our Consolidated Statements of Operations.

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 real estate project costs related to the development of new community or expansion sites are capitalized until the property is substantially complete and available for occupancy. Costs incurred to initially renovate pre-owned and repossessed homes that we acquire for our Rental Program are capitalized and the majority of costs incurred to refurbish the homes at turnover and repair the homes while occupied are expensed, unless they extend the life of the home. Certain expenditures to dealers and residents related to obtaining lessees in our communities are capitalized and amortized 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 debt 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. At December 31, 2019 and 2018 , $ 22.1 million and $ 50.3 million of Cash and Cash Equivalents, respectively, was included as a component of Cash, cash equivalents and restricted cash on the Consolidated Balance Sheets. The maximum amount of credit risk arising from cash deposits in excess of federally insured amounts was approximately $ 22.9 million and $ 49.5 million as of December 31, 2019 and 2018 , respectively.

Restricted Cash

Restricted cash consists of amounts primarily held in deposit for tax, insurance and repair escrows held by lenders in accordance with certain debt agreements. At December 31, 2019 and 2018 , $ 12.7 million and $ 12.0 million of restricted cash, respectively, was included as a component of Cash, cash equivalents and restricted cash on the Consolidated Balance Sheets

On January 1, 2018, we adopted ASU 2016-18 “Statement of Cash Flows (Topic 230): Restricted Cash.” This update required 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. Upon adoption of this standard, changes in restricted cash are reported in our Consolidated Statements of Cash Flows as operating, investing or financing activities based on the nature of the underlying activity.

Marketable Securities

Marketable securities are recorded at fair value with changes in fair value recorded in Remeasurement of marketable securities within the Consolidated Statement of Operations. We hold less than 10 percent ownership in Ingenia Communities Group. The value of marketable securities as of December 31, 2019 was $ 94.7 million and is disclosed on the Consolidated Balance Sheet.

Inventory

Inventory of manufactured homes is stated at lower of specific cost or market based on the specific identification method.

Investments in Nonconsolidated Affiliates

We apply the equity method of accounting to entities in which we do not have a direct or indirect controlling interest or for variable interest entities where we are not considered the primary beneficiary but can exercise influence over the entity with respect to its operations and major decisions. The cost method is applied when (i) the investment is minimal (typically less than 5.0 % ) and (ii) our investment is passive. Our exposure to losses associated with unconsolidated joint ventures is primarily limited to the carrying value of these investments. Accordingly, distributions from a joint venture in excess of our carrying value are recognized in earnings. We review the carrying value of our investments in nonconsolidated 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 among the factors we consider when we evaluate the existence of impairment indicators. Refer to Note 7 , “ Investments in Nonconsolidated Affiliates ,” for additional information.

Notes and Other Receivables

Notes receivable includes both installment loans for manufactured homes 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. The notes are collateralized by the underlying manufactured home sold. 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. 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 beyond the grace period required by law or by the loan agreement, notice is given to start the collection process. A specific allowance is estimated on the past due loans based on historical delinquency data and current delinquency levels.

Credit quality is evaluated at the inception of the receivable. Factors that are considered in order to determine the credit quality of the applicant include, but are not limited to: 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.

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. The carrying amounts of the identified intangible assets are included in Other assets, net on our Consolidated Balance Sheets. Refer to Note 6 , “ Intangible Assets ,” for additional information.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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. Refer to Note 13 , “ 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 and discount and premium costs are accounted for in accordance with FASB Accounting Standards Codification (“ASC”) 470-50-40, “Modifications and Extinguishments.” At December 31, 2019 and 2018 , $ 4.5 million and $ 4.7 million of line of credit deferred financing costs, respectively, were presented as a component of Other asset, net on the Consolidated Balance Sheets. At December 31, 2019 and 2018, $ 7.9 million and $ 2.4 million of deferred financing costs and discount and premium costs, respectively, were netted and presented as a component of Mortgage loans payable on the Consolidated Balance Sheets.

Temporary Equity

Temporary equity includes preferred securities that are redeemable for cash at the option of the holder or upon the occurrence of an event that is not solely within our control based on a fixed or determinable price. These preferred securities are not mandatorily redeemable for cash nor do they contain a fixed maturity date. Temporary equity is classified between Liabilities and Stockholders’ Equity on the Consolidated Balance Sheets.

Share-Based Compensation

Share-based compensation cost for service vesting restricted stock awards is measured based on the closing share price of our common stock on the date of grant. We measure the fair value of awards with performance conditions based on an estimate of shares expected to vest using the closing price of our common stock as of the grant date. If it is not probable that the performance conditions will be satisfied, we do not recognize compensation expense. 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. Refer to Note 11 , “ Share-Based Compensation ” for additional information.

Fair Value of Financial Instruments

Our financial instruments consist of cash, cash equivalents and restricted cash, accounts and notes receivable, marketable securities, accounts payable, debt, and 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.” Refer to 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. The majority of our 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. A small portion of tenant leases are for greater than two years. 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. On January 1, 2018, we adopted ASU 2014-09 “ Revenue from Contracts with Customers (Topic 606)” and the related updates subsequently issued by the FASB. The adoption of ASU 2014-09 did not result in any changes to our accounting policies for revenue recognition. Refer to Note 2 , “ Revenue ,” for additional information.

Advertising Costs

Advertising costs are expensed as incurred. As of December 31, 2019 , 2018 and 2017 , we had advertising costs of $ 6.7 million , $ 6.2 million and $ 5.9 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 thirty years for land improvements and buildings, ten years for rental homes, seven years for furniture, fixtures and equipment, four years for computer hardware and software, and seven years to twenty years for intangible assets.

Foreign Currency

The assets and liabilities of our Australian and Canadian operations, where the functional currency is the Australian dollar and 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, 2019 , we recorded a foreign currency translation gain of $ 4.5 million within Other income / (expense), net on our Consolidated Statements of Operations, as compared to a foreign currency translation loss of $ 8.4 million , for the year ended December 31, 2018 and $ 5.9 million foreign currency translation gain for the year ended December 31, 2017 .

Accounting for leases

For operating leases with a term greater than one year, the company recognizes the ROU assets and liabilities related to the lease payments on the Consolidated Balance Sheets. The lease liabilities are initially and subsequently measured at the present value of the unpaid lease payments at the lease commencement date. The ROU assets represent our right to use the underlying assets for the term of the lease and the lease liabilities represent our obligation to make lease payments arising for the agreements. The ROU asset is initially measured at cost, which comprises the initial amount of the lease liability adjusted for lease payments made at or before the lease commencement date, plus any initial direct costs incurred less any lease incentives received. The ROU asset is subsequently measured throughout the lease term at the carrying amount of the lease liability, plus unamortized initial direct costs, plus (minus) any prepaid (accrued) lease payments, less the unamortized balance of lease incentives received. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The ROU asset is periodically reduced by impairment losses. As of December 31, 2019 , we have not encountered any impairment losses. Variable lease payments, except for the ones that depend on index or rate, are excluded from the calculation of the ROU assets and lease liabilities and are recognized as variable lease expense in the Consolidated Statements of Operations in the period in which they are incurred. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. Many of our lessee agreements include options to extend the lease, which we do not include in our minimum lease terms unless they are reasonably certain to be exercised. The lease liability costs are amortized over the straight-line method over the term of the lease. Operating leases with a term of less than one year are recognized as a lease expense over the term of the lease, with no asset or liability recognized on the Consolidated Balance Sheets.

F - 15

SUN COMMUNITIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Finance leases where we are the lessee are included in Other assets, net and Other liabilities on our Consolidated Balance Sheets. The lease liabilities are initially measured in the same manner as operating leases and are subsequently measured at amortized cost using the effective interest method. The ROU asset is initially measured at cost, which comprises the initial amount of the lease liability adjusted for lease payments made at or before the lease commencement date, plus any initial direct costs incurred less any lease incentives received. For finance leases the ROU asset is subsequently amortized using the straight-line method from the lease commencement date to the earlier of the end of its useful life or the end of the lease term unless the lease transfers ownership of the underlying asset to us, or we are reasonably certain to exercise an option to purchase the underlying asset. In those cases, the ROU asset is amortized over the useful life of the underlying asset. Amortization of the ROU asset is recognized and presented separately from interest expense on the lease liability. ROU assets are periodically reduced by impairment losses. As of December 31, 2019 , we have not encountered any impairment losses. Refer to Note 19 , “ Leases ” for information regarding leasing activities.

Revenue Recognition Policies and Performance Obligations

On January 1, 2018, we adopted FASB Accounting Standards Update (“ASU”) 2014-09 “ Revenue from Contracts with Customers ” and the other related ASUs and amendments to the codification (collectively “ASC 606”). The core principle of ASC 606 is that an entity 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. A five-step transactional analysis is required to determine how and when to recognize revenue. ASC 606 applies to all contracts with customers, except those that are within the scope of other topics in the FASB accounting standards codification.

As a real estate owner and operator, the majority of our revenue is derived from site and home leases that are accounted for pursuant to ASC 842 “ Leases .” For transactions in the scope of ASC 606, we recognize revenue when control of goods or services transfers to the customer, in the amount that we expect to receive for the transfer of goods or provision of services. The adoption of ASC 606 did not result in any change to the timing and pattern of revenue recognition. Accordingly, retrospective application to prior periods or a cumulative catch-up adjustment was unnecessary.

Income from real property - Residents in our communities lease the site on which their home is located, and either own or lease their home. Resident leases are generally for one-year or month-to-month terms and are renewable by mutual agreement from us and the resident, or in some cases, as provided by jurisdictional statute. Lease revenues for sites and homes fall under the scope of ASC 842, and are accounted for as operating leases with straight-line recognition. Income from real property includes income from site leases for annual MH residents, site leases for annual recreational vehicle RV residents and site rentals to transient RV residents. Non-lease components of our site lease contracts, which are primarily provision of utility services, are accounted for with the site lease as a single lease under ASC 842. Additionally, we include collections of real estate taxes from residents within Income from real property.

Revenue from home sales - Our taxable REIT subsidiary, SHS, sells manufactured homes to current and prospective residents in our communities. Prior to adoption of ASC 606, we recognized revenue for home sales pursuant to ASC 605 “ Revenue Recognition, ” as manufactured homes are tangible personal property that can be located on any land parcel. Manufactured homes are not permanent fixtures or improvements to the underlying real estate and were therefore not considered to be subject to the guidance in ASC 360-20 “ Real Estate Sales ” by the Company. In accordance with the core principle of ASC 606, we recognize revenue from home sales at the time of closing when control of the home transfers to the customer. After closing of the sale transaction, we have no remaining performance obligation.

Rental home revenue - is comprised of rental agreements whereby we lease homes to residents in our communities. We account for these revenues under ASC 842.

Ancillary revenue - is primarily composed of proceeds from restaurant, golf, merchandise and other activities at our RV communities and is included in the scope of ASC 606. Revenues are recognized at point of sale when control of the good or service transfers to the customer and our performance obligation is satisfied. In addition, leasing of short-term vacation home rentals is included within Ancillary revenue and falls within the scope of ASC 842. Sales and other taxes that we collect concurrent with revenue-producing activities are excluded from the transaction price.

Interest income - is earned primarily on our notes receivables, which includes installment loans for manufactured homes purchased by the Company from loan originators. Interest income on these receivables is accrued based on the unpaid principal balances of the underlying loans on a level yield basis over the life of the loans. Interest income is not in the scope of ASC 606. Refer to Note 5 , “ Notes and Other Receivables ” for additional information.

Broker commissions and other revenues, net - is primarily comprised of brokerage commissions for sales of manufactured homes, where we act as agent and arrange for a third party to transfer a manufactured home to a customer within one of our communities. Brokerage commission revenues are recognized on a net basis at closing, when the transaction is completed and our performance obligations have been fulfilled. Loan loss reserve expenses for our notes receivables are also included herein. Refer to Note 5 , “ Notes and Other Receivables ” for additional information regarding our loan loss reserves.

Contract Balances

As of December 31, 2019 , and December 31, 2018 , we had $ 20.9 million and $ 16.1 million, respectively, of receivables from contracts with customers. Receivables from contracts with customers are presented as a component of Notes and other receivables, net on our Consolidated Balance Sheets. These receivables represent balances owed to us for previously completed performance obligations for sales of manufactured homes. Due to the nature of our revenue from contracts with customers, we do not have material contract assets or liabilities that fall under the scope of ASC 606.

4 . Collateralized Receivables and Transfers of Financial Assets

Prior to November 2019, 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 had no further obligations or rights with respect to the control, management, administration, servicing, or collection of the installment notes receivable. However, we were 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 were considered to be a form of continuing involvement which precluded establishing legal isolation, a necessary condition for derecognition of a financial asset, and therefore these transferred loans did not meet the requirements for sale accounting. We continued to recognize these transferred loans and we also recognized the cash proceeds on our Consolidated Balance Sheets and referred to them as collateralized receivables and as secured borrowings on collateralized receivables respectively.

In November 2019, the facts and circumstances regarding the recourse provisions, to which we remain subject, evolved such that the purchasers become subject to substantive economic risk. Accordingly, we reassessed the legal isolation analysis in consultation with legal counsel, and concluded that the transaction now achieved the sale accounting requirements for the transferred notes receivable. Following the derecognition guidance, we (a) derecognized the transferred financial assets, (b) applied the guidance in ASC paragraphs 860-20-25-1 and 860-20-30-1 on recognition and measurement of assets obtained and liabilities incurred in the sale, and (c) recognized in earnings a $ 0.6 million gain on sale.

There was no balance of collateralized receivables at December 31, 2019. The balance of the collateralized receivables was $ 106.9 million (net of allowance of $ 0.8 million ) as of December 31, 2018 . The receivables had a weighted average interest rate and maturity of 9.9 percent and 14.1 years as of December 31, 2018 .

There was no balance of secured borrowing as of December 31, 2019 . The balance of the secured borrowing was $ 107.7 million as of December 31, 2018 .

The amount of interest income and expense recognized was $ 8.0 million , $ 11.2 million and $ 13.2 million for the years ended December 31, 2019 , 2018 , and 2017 , respectively.

The change in the aggregate gross principal balance of the collateralized receivables is as follows (in thousands):

Beginning balance	December 31, 2019 — $ 107,731		December 31, 2018 — $ 129,182

The Operating Partnership

We consolidate the Operating Partnership under the guidance set forth in FASB ASC Topic 810 “Consolidation.” ASU 2015-02 modified the evaluation of whether limited partnerships and similar legal entities are VIEs or voting interest entities.

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. We are the sole general partner and generally have the power to manage and have complete control over the Operating Partnership and the obligation to absorb its losses or the right to receive its benefits.

Preferred OP Units - mandatorily redeemable

Preferred OP units at December 31, 2019 and December 31, 2018 include $ 34.7 million of Aspen preferred OP units issued by the Operating Partnership. As of December 31, 2019 , these units are convertible indirectly into 407,190 shares of our 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 market price of our common stock is $ 68.00 per share or less, 0.397 common OP units; or (b) if the market price of our common stock is greater than $ 68.00 per share, the number of common OP units is determined by dividing (i) the sum of (A) $ 27.00 plus (B) 25 percent of the amount by which the market price of our common stock exceeds $ 68.00 per share, by (ii) the per share market price of our common stock. The current preferred distribution rate is 6.5 percent . On January 2, 2024, we are required to redeem all Aspen preferred OP units that have not been converted to common OP units.

Preferred Equity - Sun NG Resorts - mandatorily redeemable

In June 2018, in connection with the investment in Sun NG Resorts, $ 35.3 million of mandatorily redeemable Preferred Equity (“Preferred Equity - Sun NG Resorts”) was purchased by unrelated third parties. The Preferred Equity - Sun NG Resorts carries a preferred rate of return of 6.0 percent per annum. The Preferred Equity - Sun NG Resorts has a 7 -year term and can be redeemed in the fourth quarter of 2022 at the holders’ option. The Preferred Equity - Sun NG Resorts balance was $ 35.2 million and $ 35.3 million at December 31, 2019 and December 31, 2018 . Refer to Note 3 , “ Real Estate Acquisitions ,” Note 8 , “ Consolidated Variable Interest Entities ,” and Note 10 , “ Equity and Temporary Equity ” for additional information.

Lines of Credit (“LOC”)

Credit agreement - In May 2019, we amended and restated our credit agreement with Citibank and certain other lenders. Pursuant to the credit agreement, we entered into a senior credit facility with Citibank and certain other lenders in the amount of $ 750.0 million , comprised of a $ 650.0 million revolving loan, with the ability to use up to $100.0 million for advances in Australian dollars, and a $ 100.0 million term loan (the “A&R Facility”). We have until March 17, 2020 to draw on the term loan. As of December 31, 2019 , we had not drawn any funds on the term loan. The credit agreement has a four-year term ending May 21, 2023, which can be extended for two additional six-month periods, 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 $ 350.0 million . If additional borrowings are made pursuant to any such additional commitments, the aggregate borrowing limit under the A&R Facility may be increased up to $ 1.1 billion .

The A&R Facility bears interest at a floating rate based on the Eurodollar rate or Bank Bill Swap Bid Rate plus a margin that is determined based on our leverage ratio calculated in accordance with the credit agreement, which margin can range from 1.20 percent to 2.10 percent for the revolving loan and 1.20 percent to 2.05 percent for the term loan. As of December 31, 2019 , the margin based on our leverage ratio was 1.20 percent on the revolving loan and 1.20 percent on the term loan. We had $ 123.6 million and zero of borrowings on the revolving loan and the term loan, respectively, as of December 31, 2019 .

The A&R 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, 2019 and December 31, 2018 , approximately $ 2.8 million and $ 3.9 million of availability was used to back standby letters of credit.

Floor plan - 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 their intent to terminate the agreement. The interest rate is 100 basis points over the greater of the prime rate as quoted in the Wall Street Journal on the first business day of each month or 6.0 percent . At December 31, 2019 , the effective interest rate was 7.0 percent . The outstanding balance was $ 3.3 million and zero as of December 31, 2019 and December 31, 2018 , respectively.

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.

2015 Equity Incentive 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 974,864 shares remaining for future issuance.

2004 Non-Employee Director Option Plan

The director plan was approved by our stockholders at the Annual Meeting of Stockholders held on July 19, 2012. The director plan amended and restated in its entirety our 2004 Non-Employee Director Stock Option Plan. At the Annual Meeting of the Stockholders held on May 17, 2018, the stockholders approved the First Amendment to Sun Communities, Inc. First Amended and Restated 2004 Non-Employee Director Option Plan to increase the number of authorized shares under the plan by 200,000 shares.

The types of awards that may be granted under the director plan are options, restricted stock and OP units. Only non-employee directors are eligible to participate in the director plan. The maximum number of options, restricted stock and OP units that may be issued under the Director Plan is 375,000 shares, with 191,774 shares remaining for future issuance.

During the year ended December 31, 2019 and 2018 , shares were granted as follows:

13 . Income Taxes

We have elected to be taxed as a REIT pursuant to Section 856(c) of the Internal Revenue Code of 1986, as amended (“Code”). In order for us to qualify as a REIT, at least 95.0 percent of our gross income in any year must be derived from qualifying sources. In addition, a REIT must distribute annually at least 90.0 percent 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, 2019 .

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 (“AMT”) in 2017 as AMT is no longer applicable for years beginning after 2017). 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 (“TRSs”) is subject to federal, state and local income taxes. The Company is also subject to income taxes in Canada as a result of the acquisition of Carefree in 2016 and in Australia as a result of our investment in Ingenia Communities Group in 2018. 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. However, we did incur $ 0.2 million of withholding taxes on distributions from our investment in Ingenia Communities Group.

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, 2019 , 2018 , and 2017 , distributions paid per share were taxable as follows (unaudited / rounded):

	Year Ended — December 31, 2019		December 31, 2018		December 31, 2017
	Amount	Percentage	Amount	Percentage	Amount	Percentage
Ordinary income (1)	$ 1.66	56.0 %	$ 1.58	56.4 %	$ 0.83	31.2 %
Capital gain	—	— %	0.13	4.8 %	—	— %
Return of capital	1.30	44.0 %	1.09	38.8 %	1.83	68.8 %
Total distributions declared	$ 2.96	100.0 %	$ 2.80	100.0 %	$ 2.66	100.0 %

(1) 98.8276 % % of the ordinary taxable dividend qualifies as Section 199A dividend for 2019 and 1.1724 % of the ordinary taxable dividend qualifies as a Qualified Dividend for 2019.

On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the “Tax Act”) was signed into law. Under the Tax Act, the corporate income tax rate is reduced from a maximum marginal rate of 35.0 percent to a flat 21.0 percent. In accordance with ASC 740, “ Accounting for Income Taxes,” we recognized the effect of tax law changes in the period of enactment even though the effective date of most provisions of the Tax Act was January 1, 2018.

Our deferred tax assets and liabilities reflect the impact of temporary differences between the amounts of assets and liabilities for financial reporting purposes and the bases of such assets and liabilities as measured by tax laws. Deferred tax assets are reduced, if necessary, by a valuation allowance to the amount where realization is more likely than not assured after considering all available evidence. Our temporary differences primarily relate to net operating loss carryforwards, and depreciation and basis differences between tax and U.S. GAAP.

At December 31, 2017, we re-measured the deferred tax assets and liabilities of our U.S. TRSs to reflect the effect of the enacted change in the tax rate under the Tax Act. We have also considered the new tax rate in assessing the need for and change to our existing valuation allowance and adjusted accordingly. Since we have recorded a full valuation allowance against substantially all of our deferred tax assets related to the U.S. TRSs, no material impact on the net deferred tax asset and the provision for income taxes was noted.

(1) Net deferred tax liability is included within Other liabilities in our Consolidated Balance Sheets.

Our U.S. TRS operating loss carryforwards are $ 75.3 million, or $ 15.6 million after tax, including SHS loss carryforwards of $ 73.0 million , or $ 15.3 million after tax, as of December 31, 2019 . The loss carryforwards will begin to expire in 2023 through 2035 if not offset by future taxable income. In addition, our Canadian subsidiaries have operating loss carryforwards of $ 9.1 million , or $ 2.4 million after tax, as of December 31, 2019 . The loss carryforwards will begin to expire in 2033 through 2038 if not offset by future taxable income.

We had no unrecognized tax benefits as of December 31, 2019 and 2018 . We expect no significant increases or decreases in unrecognized tax benefits due to changes in tax positions within one year of December 31, 2019 .

We classify certain state taxes as income taxes for financial reporting purposes. We recorded a provision for state income taxes of $ 0.9 million for the year ended December 31, 2019 , $ 0.7 million for the year ended December 31, 2018 , and $ 0.7 million for the year ended December 31, 2017 .

As previously noted, certain of 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 application of significant judgment. 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, 2011 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, 2012 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, 2019 , 2018 and 2017 .

In 2017, SHS underwent an audit by the Internal Revenue Service for the 2015 tax year. Upon conclusion of the audit, no adjustment was required.

16 . Fair Value of Financial Instruments

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

ASC Topic 820 “ Fair Value Measurements and Disclosures, ” requires disclosure regarding determination of fair value 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:

F - 38

SUN COMMUNITIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Marketable Securities

Marketable securities held by us and accounted for under the ASC 321 “ Investment Equity Securities ” are measured at fair value. Any change in fair value is recognized in the Consolidated Statement of Operations in Remeasurement of marketable securities in accordance with ASU 2016-01 “ Financial Instruments - Overall (Subtopic 825-10): Recognition and measurement of financial assets and financial liabilities .” The fair value is measured by the quoted unadjusted share price which is readily available in active markets (Level 1).

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 5 , “ Notes and Other Receivables .”

Notes Receivable from Real Estate Developers

The net carrying value of the notes receivable from real estate developers estimates the fair value as the interest rates in the portfolio are comparable to current prevailing market rates (Level 2). Refer Note 5 , “ 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 9 , “ Debt and Lines of Credit .”

Collateralized Receivables and Secured Borrowing

The fair value of these financial instruments offset each other as our collateralized receivables represent a transfer of financial assets and the cash proceeds received from these transactions have been classified as a secured borrowing 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 4 , “ 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 nonperformance 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 those instruments.

17 . Recent Accounting Pronouncements

Recent Accounting Pronouncements - Adopted

In February 2016, the FASB issued ASC 2016-02 codified in ASC Topic 842, Leases, which amends the guidance in former ASC Topic 840, Leases. On January 1, 2019, we adopted ASC 2016-02. The new standard increases transparency and comparability most significantly by requiring the recognition by lessees of right of-use (“ROU”) assets and lease liabilities on the balance sheet for those leases classified as operating leases and disclose key information about leasing arrangements. As amended by ASU 2018-11, comparative reporting periods are presented in accordance with Topic 840, while periods subsequent to the effective date are presented in accordance with Topic 842. The Company elected the package of practical expedients, which permits the Company not to reassess expired or existing contracts containing a lease, the lease classification for expired or existing contracts, initial direct costs for any existing leases. The Company elected not to allocate lease obligation between lease and non-lease components of our agreements for both leases where we are a lessor and leases where we are a lessee. The Company did not elect the hindsight practical expedient, which permits the company to use hindsight in determining the lease terms and impairment implications. The Company did not elect to use a portfolio approach in the valuation of ROU assets and corresponding liabilities. Some ROU assets include an extension option, which is included in the ROU assets and liabilities only if we are reasonably certain to exercise.

Lessor Accounting

Our income from real property and rental home revenue streams are derived from rental agreements where we are the lessor. Our recognition of rental revenue remains mainly consistent with previous guidance, apart from the narrower definition of initial direct costs that can be capitalized. ASC 842 limits the definition of initial direct costs to only the incremental costs of signing a lease. Internal sales employees’ compensation, payroll-related fringe benefits, certain legal fees rendered prior to the execution of a lease, negotiation costs, advertising and other origination effort costs no longer meet the definition of initial direct costs under the new standard, and will be accounted for as general and administrative expense in our consolidated statements of operations. ASC 842 permits the capitalization of direct commission costs. The application of ASC 842 resulted in an immaterial impact on the statement of consolidated operations.

Our leases with customers are classified as operating leases. Lease income from tenants is recognized on a straight-line basis over the terms of the relevant lease agreement and is included within income from real property, rental home revenue and ancillary revenue on the Consolidated Statements of Operations. Revenue is not recognized when collection is not reasonably assured. When collectability is not reasonably assured, the resident is placed on non-accrual status and revenue is recognized when cash payments are received.

Lessee Accounting

We determine if an arrangement is a lease at inception. Our operating lease agreements are primarily for executive office spaces, ground leases at certain communities, and certain equipment leases. The ROU asset and ROU liabilities are included within Other assets, net and Other liabilities on the Consolidated Balance Sheets. For operating leases with a term greater than one year, the company recognizes the ROU assets and liabilities related to the lease payments on the Consolidated Balance Sheets. The lease liabilities are initially and subsequently measured at the present value of the unpaid lease payments at the lease commencement date. The ROU assets represent our right to use the underlying assets for the term of the lease and the lease liabilities represent our obligation to make lease payments arising for the agreements. The ROU asset is initially measured at cost, which comprises the initial amount of the lease liability adjusted for lease payments made at or before the lease commencement date, plus any initial direct costs incurred less any lease incentives received. The ROU asset is subsequently measured throughout the lease term at the carrying amount of the lease liability, plus unamortized initial direct costs, plus (minus) any prepaid (accrued) lease payments, less the unamortized balance of lease incentives received. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The ROU asset is periodically reduced by impairment losses. As of December 31, 2019 , we have not encountered any impairment losses. Variable lease payments, except for the ones that depend on index or rate, are excluded from the calculation of the ROU assets and lease liabilities and are recognized as variable lease expense in the Consolidated Statements of Operations in the period in which they are incurred. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. Many of our lessee agreements include options to extend the lease, which we do not include in our minimum lease terms unless they are reasonably certain to be exercised. The lease liability costs are amortized over the straight-line method over the term of the lease. Operating leases with a term of less than one year are recognized as a lease expense over the term of the lease, with no asset or liability recognized on the Consolidated Balance Sheets. Finance leases where we are the lessee are included in Other assets, net and Other liabilities on our Consolidated Balance Sheets. The lease liabilities are initially measured in the same manner as operating leases and are subsequently measured at amortized cost using the effective interest method. The ROU asset is initially measured at cost, which comprises the initial amount of the lease liability adjusted for lease payments made at or before the lease commencement date, plus any initial direct costs incurred less any lease incentives received.

For finance leases the ROU asset is subsequently amortized using the straight-line method from the lease commencement date to the earlier of the end of its useful life or the end of the lease term unless the lease transfers ownership of the underlying asset to us, or we are reasonably certain to exercise an option to purchase the underlying asset. In those cases, the ROU asset is amortized over the useful life of the underlying asset. Amortization of the ROU asset is recognized and presented separately from interest expense on the lease liability. ROU assets are periodically reduced by impairment losses. As of December 31, 2019 , we have not encountered any impairment losses. Refer to Note 19 , “ Leases ” for information regarding leasing activities.

Recent Accounting Pronouncements - Not Yet Adopted

In June 2016, the FASB issued ASU 2016-13 “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments . ” “CECL” 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. As of January 1, 2020, we adopted the fair value option for our installment notes receivable and the notes receivable within the GTSC joint venture which resulted in fair value adjustments of $ 0.3 million and $ 0.6 million, respectively. We do not expect the impact of the adoption of CECL on the remaining in scope financial instruments to be material.

Lessor Accounting

We are not the lessor for any finance leases as of December 31, 2019 . Over 95 percent of our operating leases where we are the lessor are either month to month or for a time period not to exceed one year. As of the reporting date, future minimum lease payments would not exceed twelve months. Similarly, over 95 percent of our investment property, net on the Consolidated Balance Sheets, and related depreciation amounts relate to assets whereby we are the lessor under an operating lease.

20 . Related Party Transactions

Lease of Executive Offices. Gary A. Shiffman, together with certain of his family members, indirectly owns an equity interest of approximately 28.1 percent 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 103,100 rentable square feet of permanent space. The initial term of the lease is until October 31, 2026, and the average gross base rent is $ 18.95 per square foot until October 31, 2020 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.

Legal Counsel . During 2017- 2019 , Jaffe, Raitt, Heuer, & Weiss, Professional Corporation acted as our general counsel and represented us in various matters. Arthur A. Weiss is the Chairman of the Board of Directors and a shareholder of such firm. We incurred legal fees and expenses owed to Jaffe, Raitt, Heuer, & Weiss of approximately $ 11.1 million , $ 7.1 million and $ 5.0 million in the years ended December 31, 2019 , 2018 and 2017 , 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.

21 . Subsequent Events

Subsequent to the quarter ended December 31, 2019, we acquired one MH community located in East Falmouth, Massachusetts for $ 13.5 million , containing 230 RV sites. In conjunction with the acquisition, the Operating Partnership created a new class of OP units named Series E preferred OP units. As of February 13, 2020, 90,000 Series E preferred OP units were outstanding. The Series E preferred OP units provide for quarterly distributions on the $ 100 per unit issue price of 5.3 percent per year until January 9, 2022, and 5.5 percent per year thereafter. Subject to certain limitations, each Series E Preferred Unit is exchangeable at any time after the first anniversary of its issuance date into that number of shares of the Company’s common stock equal to the quotient obtained by dividing $ 100.00 by $ 145.00 (as such ratio is subject to adjustment for certain capital events).

On January 13, 2020, the Operating Partnership’s partnership agreement was amended to revise the terms of 270,000 of the operating partnership’s outstanding 1,283,819 Aspen preferred OP units. With respect to those 270,000 units, the automatic redemption date was extended to January 2, 2034 (as compared to January 2, 2024 for the other Aspen preferred OP units) and the annual distribution rate was reduced to 3.8 percent (as compared to a rate determined by a formula, currently 6.5 percent , for the other Aspen preferred OP units).

We have evaluated our Consolidated Financial Statements for subsequent events through the date that this Form 10-K was issued.
