EXPLANATORY NOTE

​

This report combines the annual reports on Form 10-K for the year ended December 31, 20222023 of CubeSmart (the “Parent Company” or “CubeSmart”) and CubeSmart, L.P. (the “Operating Partnership”). The Parent Company is a Maryland real estate investment trust (“REIT”), that owns its assets and conducts its operations through the Operating Partnership, a Delaware limited partnership, and subsidiaries of the Operating Partnership. The Parent Company, the Operating Partnership and their consolidated subsidiaries are collectively referred to in this report as the “Company”. In addition, terms such as “we”, “us”, or “our” used in this report may refer to the Company, the Parent Company and/or the Operating Partnership.

​

The Parent Company is the sole general partner of the Operating Partnership and, as of December 31, 2022,2023, owned a 99.4% interest in the Operating Partnership. The remaining 0.6% interest consists of common units of limited partnership interestOP Units issued by the Operating Partnership to third parties in exchange for contributions of properties to the Operating Partnership. As the sole general partner of the Operating Partnership, the Parent Company has full and complete authority over the Operating Partnership’s day-to-day operations and management.

​

Management operates the Parent Company and the Operating Partnership as one enterprise. The management teams of the Parent Company and the Operating Partnership are identical, and their constituents are officers of both the Parent Company and of the Operating Partnership.

​

There are a few differences between the Parent Company and the Operating Partnership, which are reflected in the note disclosures in this report. The Company believes it is important to understand the differences between the Parent Company and the Operating Partnership in the context of how these entities operate as a consolidated enterprise. The Parent Company is a REIT, whose only material asset is its ownership of the partnership interests of the Operating Partnership. As a result, the Parent Company does not conduct business itself, other than acting as the sole general partner of the Operating Partnership, issuing public equity from time to time and guaranteeing the debt obligations of the Operating Partnership. The Operating Partnership holds substantially all of the assets of the Company and, directly or indirectly, holds the ownership interests in the Company’s real estate ventures. The Operating Partnership conducts the operations of the Company’s business and is structured as a partnership with no publicly traded equity. Except for net proceeds from equity issuances by the Parent Company, which are contributed to the Operating Partnership in exchange for partnership units, the Operating Partnership generates the capital required by the Company’s business through the Operating Partnership’s operations, by the Operating Partnership’s direct or indirect incurrence of indebtedness or through the issuance of partnership units of the Operating Partnership or equity interests in subsidiaries of the Operating Partnership.

​

The substantive difference between the Parent Company’s and the Operating Partnership’s filings is the fact that the Parent Company is a REIT with public equity, while the Operating Partnership is a partnership with no publicly traded equity. In the financial statements, this difference is primarily reflected in the equity (or capital for the Operating Partnership) section of the consolidated balance sheets and in the consolidated statements of equity (or capital). Apart from the different equity treatment, the consolidated financial statements of the Parent Company and the Operating Partnership are nearly identical.

​

The Company believes that combining the annual reports on Form 10-K of the Parent Company and the Operating Partnership into a single report will:

​

​

In order to highlight the differences between the Parent Company and the Operating Partnership, the separate sections in this report for the Parent Company and the Operating Partnership specifically refer to the Parent Company and the Operating Partnership. In the sections that combine disclosures of the Parent Company and the Operating Partnership, this report refers to such disclosures as those of the Company. Although the Operating Partnership is generally the entity that directly or indirectly enters into contracts and real estate ventures and holds assets and debt, reference to the Company is appropriate because the business is one enterprise and the Parent Company operates the business through the Operating Partnership.

​

As general partner with control of the Operating Partnership, the Parent Company consolidates the Operating Partnership for financial reporting purposes, and the Parent Company does not have significant assets other than its investment in the Operating Partnership. Therefore, the assets and liabilities of the Parent Company and the Operating Partnership are the same on their respective financial

with each other to understand the results of the Company’s operations on a consolidated basis and how management operates the Company.

​

This report also includes separate Item 9A - Controls and Procedures sections, signature pages and Exhibits 31 and 32 certifications for each of the Parent Company and the Operating Partnership, in order to establish that the Chief Executive Officer and the Chief Financial Officer of the Parent Company and the Chief Executive Officer and the Chief Financial Officer of the Operating Partnership have made the requisite certifications and that the Parent Company and the Operating Partnership are compliant with Rule 13a-15 or Rule 15d-15 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and 18 U.S.C. §1350.

ITEM 1. BUSINESS

​

Overview

​

We are a self-administered and self-managed real estate company focused primarily on the ownership, operation, management, acquisition and development of self-storage properties in the United States.

​

As of December 31, 2022,2023, we owned (or partially owned and consolidated) 611 self-storage properties located in 24 states and in the District of Columbia containing an aggregate of approximately 44.1 million rentable square feet. As of December 31, 2022,2023, approximately 90.3%89.8% of the rentable square footage at our owned stores was leased to approximately 377,000379,000 customers, and no single customer represented a significant concentration of our revenues. As of December 31, 2022,2023, we owned stores in the District of Columbia and the following 24 states: Arizona, California, Colorado, Connecticut, Florida, Georgia, Illinois, Indiana, Maryland, Massachusetts, Minnesota, Nevada, New Jersey, New Mexico, New York, North Carolina, Ohio, Pennsylvania, Rhode Island, South Carolina, Tennessee, Texas, Utah and Virginia. In addition, as of December 31, 2022,2023, we managed 668795 stores for third parties (including 77 stores containing an aggregate of approximately 5.6 million net rentable square feet as part of six separate unconsolidated real estate ventures) bringing the total number of stores we owned and/or managed to 1,279.1,406. As of December 31, 2022,2023, we managed stores for third parties in the District of Columbia and the following 3840 states: Alabama, Arizona, Arkansas, California, Colorado, Connecticut, Delaware, Florida, Georgia, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, Nebraska, Nevada, New Hampshire, New Jersey, New Mexico, New York, North Carolina, Ohio, Oklahoma, Pennsylvania, Rhode Island, South Carolina, Tennessee, Texas, Vermont, Virginia, Washington and Wisconsin.

​

Our self-storage properties are designed to offer affordable and easily-accessible storage space for our residential and commercial customers. Our customers rent storage cubes for their exclusive use, typically on a month-to-month basis. Additionally, some of our stores offer outside storage areas for vehicles and boats. Our stores are designed to accommodate both residential and commercial customers, with features such as wide aisles and load-bearing capabilities for large truck access. All of our stores have a storage associate or automated kiosk available to assist our customers during business hours, and 334,336, or approximately 54.7%55.0%, of our owned stores have a manager who resides in an apartment at the store. Our customers can access their storage cubes during business hours, and some of our stores provide customers with 24-hour access through computer-controlled access systems. Our goal is to provide customers with the

highest standard of physical attributes and service in the industry. To that end, 510, or approximately 83.5%, of our owned stores include climate-controlled cubes.

Investment and Market Selection Process

​

We maintain a disciplined and focused process in the acquisition and development of self-storage properties. Our investment committee is comprised of four seniorexecutive officers who oversee our investment process. Our investment process involves six stages — identification, initial due diligence, economic assessment, investment committee approval (and when required, the approval of our Board of Trustees (the “Board”)), final due diligence and documentation. Through our investment committee, we intend to focus on the following criteria:

​

​

​

​

Segment

​

We have one reportable segment: we own, operate, develop, manage and acquire self-storage properties.

​

Concentration

​

Our self-storage properties are located in major metropolitan areas as well as suburban areas and have numerous customers per store. No single customer represented a significant concentration of our 20222023 revenues. Our stores in New York, Florida, California and Texas provided approximately 17%, 15%, 11% and 9%, respectively, of our total revenues for the year ended December 31, 2023. Our stores in New York, Florida, California and Texas provided approximately 16%, 15%, 11% and 9%, respectively, of our total revenues for the year ended December 31, 2022. Our stores in New York, Florida, Texas and California provided approximately 19%, 15%, 9% and 8%, respectively, of our total revenues for the year

manner consistent with maintaining a strong financial position and future financial flexibility, subject to limitations on incurrence of indebtedness inunder our unsecured credit facilities and the indenture that governs our unsecured notes. These capital sources may include existing cash, borrowings under our revolving credit facility, additional secured or unsecured financings, sales of common or preferred shares of the Parent Company in public offerings or private placements, additional issuances of debt securities, issuances of common or preferred units in our Operating Partnership in exchange for contributed properties and formations of joint ventures. We also may sell stores that have unattractive risk-adjusted returns and use the sales proceeds to fund other acquisitions.

​

Competition

​

Self-storage properties compete based on a number of factors, including location, rental rates, occupancy, security, suitability of the store’s design to prospective customers’ needs and the manner in which the store is maintained, operated and marketed. In particular, the number of competing self-storage properties in a market could have a material effect on our occupancy levels, rental rates and on the overall operating performance of our stores. We believe that the primary competition for potential customers of any of our self-storage properties comes from other self-storage providers within a three-mile radius of that store. We emphasize customer service, convenience, security, professionalism, and cleanliness and, therefore, we believe our stores are well-positioned within their respective markets, and we emphasize customer service, convenience, security, professionalism and cleanliness.markets.

​

Our key competitors include local and regional operators as well as the other public self-storage REITs, including, but not limited to, Public Storage, Extra Space Storage Inc., Life Storage, Inc. and National Storage Affiliates Trust. These companies, some of which operate significantly more stores than we do and have greater resources than we have, and other entities may be able to accept more risk than we determine is prudent for us, including risks with respect to the geographic proximity of investments and the payment of higher acquisition prices. This competition may reduce the number of suitable acquisition opportunities available to us, increase the price required to acquire stores and reduce the demand for self-storage space at our stores. Nevertheless, we believe that our experience in operating, managing, acquiring, developing and obtaining financing for self-storage properties should enable us to compete effectively.

​

Government Regulation

​

We are subject to various laws, ordinances and regulations, including regulations relating to lien sale rights and procedures, consumer protection measures and various federal, state and local regulations that apply generally to the ownership of real property and the operation of self-storage properties.

​

Under the Americans with Disabilities Act of 1990 and applicable state accessibility act laws (collectively, the “ADA”), all places of public accommodation are required to meet federal requirements related to physical access and use by disabled persons. A number of other federal, state and local laws may also impose access and other similar requirements at our stores. A failure to comply with the ADA or similar state or local requirements could result in the governmental imposition of fines or the award of damages to private litigants affected by the noncompliance. Although we believe that our stores comply in all material respects with these requirements (or would be eligible for applicable exemptions from material requirements because of adaptive assistance provided), a determination that one or more of our stores or websites is not in compliance with the ADA or similar state or local requirements would result in the incurrence of additional costs associated with bringing them into compliance.

​

Under various federal, state and local laws, ordinances and regulations, an owner or operator of real property may become liable for the costs of removal or remediation of hazardous substances released on or in its property. These laws often impose liability without regard to

Table of Contents

We are not aware of any environmental cleanup liability that we believe will have a material adverse effect on us. We cannot provide assurance, however, that these environmental assessments and investigations have revealed or will reveal all potential environmental liabilities, that no prior owner created any material environmental condition not known to us or the independent consultant or that future events or changes in environmental laws will not result in the imposition of environmental liability on us.

​

We have not received notice from any governmental authority of any material noncompliance, claim or liability in connection with any of our stores, nor have we been notified of a claim for personal injury or property damage by a private party in connection with any of our stores relating to environmental conditions.

​

We are not aware of any environmental condition with respect to any of our stores that could reasonably be expected to have a material adverse effect on our financial condition or results of operations, and we do not expect that the cost of compliance with environmental regulations will have a material adverse effect on our financial condition or results of operations. We cannot provide assurance, however, that this will continue to be the case.

​

Insurance

​

We carry comprehensive liability, fire, casualty, extended coverage and rental loss insurance covering all of the properties in our portfolio. We also carry environmental insurance coverage on certain stores in our portfolio. 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. We do not carry insurance for losses such as loss from civil unrest, riots, war or acts of God, pandemics, and, in some cases, flood and environmental hazards, because such coverage is either not available or not available at commercially reasonable rates. Some of our policies, such as those covering losses due to terrorism, hurricanes, floods, earthquakes and earthquakes,windstorms, are insured subject to limitations involving large deductibles or co-payments and policy limits that may not be sufficient to cover losses. Additionally, we use a combination of insurance products, some of which include deductibles and self-insured retention amounts, to provide risk mitigation for potential liabilities associated with automobiles, workers’ compensation, employment practices, general contractors, cyber risks, crime, directors and officers, employee health-care benefits, fiduciary obligations, managerial errors and omissions and personal injuries that might be sustained at our stores.

​

When recruiting new teammates, our talent managementacquisition team engages with our store management teams and corporate leaders to identify a pool of potential candidates to serve our customers and deliver best-in-class customer service. We recruited, hired and trained 1,5051,651 teammates during the year ended December 31, 2022.2023.

ITEM 1A.  RISK FACTORS

​

Overview

​

An investment in our securities involves various risks. Investors should carefully consider the risks set forth below together with other information contained in this Report. These risks are not the only ones that we may face. Additional risks not presently known to us, or that we currently consider immaterial, may also impair our business, financial condition, operating results and ability to make distributions to our shareholders.

​

Risks Related to our Business and Operations

​

Adverse macroeconomic and business conditions may significantly and negatively affect our rental rates, occupancy levels and therefore our results of operations.

​

We are susceptible to the effects of adverse macro-economic events that can result in higher unemployment, shrinking demand for products, large-scale business failures and tight credit markets. Our results of operations are sensitive to changes in overall economic conditions that impact consumer spending, including discretionary spending, as well as to increased bad debts due to recessionary pressures. Adverse economic conditions affecting disposable consumer income, such as employment levels, business conditions, inflation, deflation, interest rates, tax rates and fuel and energy costs, could reduce consumer spending or cause consumers to shift their spending to other products and services. A general reduction in the level of discretionary spending or shifts in consumer discretionary spending could adversely affect our growth and profitability.

​

It is difficult to determine the breadth and duration of economic and financial market disruptions (including those in international markets) and the many ways in which they may affect our customers and our business in general. Nonetheless, financial and macroeconomic disruptions could have a significant adverse effect on our sales, profitability and results of operations.

​

Our financial performance is dependent upon economic and other conditions of the markets in which our stores are located.

​

We are susceptible to adverse developments in the markets in which we operate, such as business layoffs or downsizing, industry slowdowns, relocations of businesses, changing demographics and other factors. Our stores in New York, Florida, California and Texas accounted for approximately 16%17%, 15%, 11% and 9%, respectively, of our total 20222023 revenues. As a result of this geographic concentration of our stores, we are particularly susceptible to adverse market conditions in these areas. Any adverse economic or real estate developments in these markets, or in any of the other markets in which we operate, or any decrease in demand for self-storage space resulting from the local business climate, could adversely affect our rental revenues, which could impair our ability to satisfy our debt service obligations and pay distributions to our shareholders.

​

Our business, financial condition,results of operations and share price have, and may in the future be, impacted by the COVID-19 pandemic and other potential future pandemics and such impact could be materially adverse.

​

Since the first quarter of 2020, the world has been impacted by the COVID-19 pandemic, which has resulted in global business disruptions and significant volatility in U.S. and international debt and equity markets. The extent to which the COVID-19 pandemic and any other potential future pandemics ultimately impact our business, results of operations, financial condition and share price will depend on numerous evolving factors, including, among others: the duration and scope of such pandemic; actions that have been and continue to be taken by governmental entities, individuals and businesses in response to such pandemic; the impact on economic activity from such pandemic and actions taken in response thereto; the impact on capital availability and costs of capital; the impact on our employees any other operational disruptions or difficulties we may face; and, the effect on our customers and their ability to make rental payments. Any of these events, individually or in aggregate, could have a material adverse impact on the Company’s business, financial condition, results of operations and share price.

​

We face risks associated with property acquisitions.

​

We intend to continue to acquire individual and portfolios of self-storage properties. The purchase agreements that we enter into in connection with acquisitions typically contain closing conditions that need to be satisfied before the acquisitions can be consummated. The satisfaction of many of these conditions is outside of our control, and we therefore cannot assure that any of our pending or future acquisitions will be consummated. These conditions include, among other things, satisfactory examination of the title, zoning and entitlements to the properties, the ability to obtain title insurance and customary closing deliverables and conditions. Moreover, in the

In addition, we often do not obtain third-party appraisals of acquired properties and instead rely on internal value determinations.

We will incur costs and will face integration challenges when we acquire or develop additional stores.

​

As we acquire or develop additional self-storage properties and bring additional self-storage properties onto our third-party management platform, we will be subject to risks associated with integrating and managing new stores, including customer retention and mortgage default risks. In the case of a large portfolio purchase, we could experience strains in our existing systems and management capacities. In addition, acquisitions or developments may cause disruptions in our operations and divert management’s attention away from day-to-day operations. Furthermore, our net income may decline because we will be required to depreciate/amortize in future periods costs for acquired real property and intangible assets. Our failure to successfully integrate any future acquisitions into our portfolio could have an adverse effect on our operating costs and our ability to make distributions to our shareholders.

​

The acquisition of new stores that lack operating history with us will make it more difficult to predict financial performance.

​

We intend to continue to acquire individual and portfolios of self-storage properties. These acquisitions could fail to perform in accordance with expectations. If we fail to accurately estimate occupancy levels, rental rates, operating costs or costs of improvements to bring an acquired store up to the standards established for our intended market position, the performance of the store may be below expectations. Acquired stores may have characteristics or deficiencies affecting their valuation or revenue potential that we have not yet discovered. We cannot assure that the performance of stores acquired by us will increase or be maintained under our management.

​

Our development activities may be more costly or difficult to complete than we anticipate.

​

We intend to continue to develop self-storage properties where market conditions warrant such investment. Once made, these investments may not produce results in accordance with our expectations. Risks associated with development and construction activities include:

​

If we are unable to promptly re-lease our cubes or if the rates upon such re-letting are significantly lower than expected, our business and results of operations would be adversely affected.

​

We derive revenues principally from rents received from customers who rent cubes at our self-storage properties under month-to-month leases. Any delay in re-leasing cubes as vacancies arise would reduce our revenues and harm our operating results. In addition, lower than expected rental rates upon re-leasing could adversely affect our revenues and impede our growth.

​

Store ownership through joint ventures may limit our ability to act exclusively in our interest.

​

We co-invest with, and we may continue to co-invest with, third parties through joint ventures. In any such joint venture, we may not be in a position to exercise sole decision-making authority regarding the stores owned through joint ventures. Investments in joint ventures may, under certain circumstances, involve risks not present when a third party is not involved, including the possibility that joint venture partners might become bankrupt or fail to fund their share of required capital contributions. Joint venture partners may have business interests or goals that are inconsistent with our business interests or goals and may be in a position to take actions contrary to our policies or objectives. Such investments also have the potential risk of impasse on strategic decisions, such as a sale, in cases where neither we nor the joint venture partner would have full control over the joint venture. In other circumstances, joint venture partners may have the ability without our agreement to make certain major decisions, including decisions about sales, capital expenditures, and/or financing. Any disputes that may arise between us and our joint venture partners could result in litigation or arbitration that could increase our expenses and distract our officers and/or Trustees from focusing their time and effort on our business. In addition, we might in certain circumstances be liable for the actions of our joint venture partners, and the activities of a joint venture could adversely affect our ability to qualify as a REIT, even though we do not control the joint venture.

​

We face significant competition for customers and acquisition and development opportunities.

​

Actions by our competitors may decrease or prevent increases of the occupancy and rental rates of our stores. We compete with numerous developers, owners and operators of self-storage properties, including other REITs, as well as on-demand storage providers, some of which own or may in the future own stores similar to ours in the same submarkets in which our stores are located and some of which may have greater capital resources. In addition, due to the relatively low cost of each individual self-storage property, other developers, owners and operators have the capability to build additional stores that may compete with our stores.

​

If our competitors build new stores that compete with our stores or offer space at rental rates near or below the rental rates we currently charge our customers, we may lose potential customers, and we may be pressured to reduce our rental rates below those we currently charge in order to retain customers when our customers’ leases expire. As a result, our financial condition, cash flow, cash available for distribution, market price of our shares and ability to satisfy our debt service obligations could be materially adversely affected. In addition, increased competition for customers may require us to make capital improvements to our stores that we would not have otherwise made. Any unbudgeted capital improvements we undertake may reduce cash available for distributions to our shareholders or for satisfaction of our debt service obligations.

​

We also face significant competition for acquisitions and development opportunities. Some of our competitors have greater financial resources than we do and a greater ability to borrow funds to acquire stores. These competitors may also be willing to accept more risk than we can prudently manage, including risks with respect to the geographic proximity of investments and the payment of higher acquisition prices. This competition for investments may reduce the number of suitable investment opportunities available to us, may increase acquisition costs and may reduce demand for self-storage space in certain areas where our stores are located and, as a result, adversely affect our operating results.

​

and ordinances, environmental considerations and other factors also might make it impractical or undesirable to use insurance proceeds to replace a store after it has been damaged or destroyed. In addition, if the damaged stores are subject to recourse indebtedness, we would continue to be liable for the indebtedness, even if these stores were irreparably damaged.

​

Additionally, we use a combination of insurance products, some of which include deductibles and self-insured retention amounts, to provide risk mitigation for potential liabilities associated with automobiles, workers’ compensation, employment practices, general contractors, cyber risks, crime, directors and officers, employee health-care benefits, fiduciary obligations, managerial errors and omissions, and personal injuries that might be sustained at our stores. Liabilities associated with the risks that are retained by us are estimated, in part, by considering historical claims experience and actuarial assumptions. Our results of operations could be materially impacted by claims and other expenses related to such insurance plans if future occurrences and claims differ from these assumptions and historical trends.

​

Our insurance coverage may not comply with certain loan requirements.

​

Certain of our stores serve as collateral for our mortgage-backed debt, some of which we assumed in connection with our acquisition of stores and requires us to maintain insurance, deductibles, retentions and other policy terms at levels that may not be commercially reasonable in the current insurance environment. We may be unable to obtain required insurance coverage if the cost and/or availability make it impractical or impossible to comply with debt covenants. If we cannot comply with a lender’s requirements, the lender could declare a default, which could affect our ability to obtain future financing and have a material adverse effect on our results of operations and cash flows and our ability to obtain future financing. In addition, we may be required to self-insure against certain losses or our insurance costs may increase.

​

We are subject to risks from the consequences of climate change, including severe weather events, as well as the transition to a low-carbon economy and other steps taken to prevent or mitigate climate change.

​

Our self-storage properties are located in areas that may be subject to the direct impacts of climate change, such as increased destructive weather events like floods, sea level rise, fires, and drought, which could result in significant damage to our stores, increased capital expenditures, increased expenses, reduced revenues, or reduced demand for our self-storage space. Indirect impacts of climate change could also adversely impact our business, including through increased costs, such as insurance costs or regulatory compliance costs. Potential governmental, political and social pressure related to climate change and actions to mitigate climate change could in the future result in (i) costly changes to newly developed stores or retrofits of our existing stores to reduce carbon emissions through multiple avenues, including changes to insulation, space configuration, lighting, heating, and air conditioning, (ii) increased energy costs as a result of transitioning to less carbon-intensive, but more expensive, sources of energy to operate our stores, and (iii) consumers reducing their individual carbon footprints by owning fewer durable material consumer goods, collectibles, and other such items requiring storage, resulting in a reduced demand for our self-storage space. In addition, our reputation and investor relationships could be damaged as a result of our involvement with activities perceived to be causing or exacerbating climate change, as well as any decisions we make to continue to conduct or change our activities in response to considerations relating to climate change.

​

Potential liability for environmental contamination could result in substantial costs.

​

We are subject to federal, state and local environmental laws, ordinances and regulations that apply generally to the ownership of real property and the operation of self-storage properties. If we fail to comply with those laws, ordinances and regulations, we could be subject to significant fines or other governmental sanctions.

​

Under various federal, state and local laws, ordinances and regulations, an owner or operator of real estate may be required to investigate and clean up hazardous or toxic substances or petroleum product releases at a property and may be held liable to a governmental entity or to third parties for property damage and for investigation and clean-up costs incurred by such parties in connection with contamination. Such liability may be imposed whether or not the owner or operator knew of, or was responsible for, the presence of these hazardous or toxic substances. The cost of investigation, remediation or removal of such substances may be substantial, and the presence of such substances, or the failure to properly remediate such substances, may adversely affect our ability to sell or rent such property or to borrow using such property as collateral. In addition, in connection with the ownership, operation and management of properties, we are potentially liable for property damage or injuries to persons and property.

​

Our practice is to conduct or obtain environmental assessments in connection with the acquisition or development of additional stores. We carry environmental insurance coverage on certain stores in our portfolio. We obtain or examine environmental assessments from qualified and reputable environmental consulting firms (and intend to conduct such assessments prior to the acquisition or development of additional stores). The environmental assessments received to date have not revealed, nor do we have actual knowledge of, any

environmental liability that we believe will have a material adverse effect on us. However, we cannot assure that our environmental assessments have identified or will identify all material environmental conditions, that any prior owner of any property did not create a material environmental condition not actually known to or discoverable by us, that environmental conditions on neighboring properties

substantially all of our assets through the Operating Partnership and its subsidiaries and joint ventures further complicates the application of the REIT requirements for us. Even a technical or inadvertent mistake could jeopardize our REIT status, and, given the highly complex nature of the rules governing REITs and the ongoing importance of factual determinations, we cannot provide any assurance that we will continue to qualify as a REIT. Congress and the IRS may make changes to the tax laws and regulations, and the courts might issue new rulings that make it more difficult, or impossible, for us to remain qualified as a REIT. If we fail to qualify as a REIT for federal income tax purposes and are able to avail ourselves of one or more of the statutory savings provisions in order to maintain our REIT status, we would nevertheless be required to pay penalty taxes of $50,000 or more for each such failure.

​

If we fail to qualify as a REIT for federal income tax purposes, and are unable to avail ourselves of certain savings provisions set forth in the Internal Revenue Code of 1986, as amended (the “Code”), we would be subject to federal income tax at regular corporate rates on all of our income. As a taxable

subject to a 100% penalty tax. In general, prohibited transactions are sales or other dispositions of property held primarily for sale to customers in the ordinary course of business. The determination as to whether a particular sale is a prohibited transaction depends on the facts and circumstances related to that sale. We cannot guarantee that sales of our properties would not be prohibited transactions unless we comply with certain statutory safe-harbor provisions.

​

In addition, any net taxable income earned directly by our taxable REIT subsidiaries, or through entities that are disregarded for federal income tax purposes as entities separate from our taxable REIT subsidiaries, will be subject to federal and possibly state corporate income tax. We have elected to treat some of our subsidiaries as taxable REIT subsidiaries, and we may elect to treat other subsidiaries as taxable REIT subsidiaries in the future. In this regard, several provisions of the laws applicable to REITs and their subsidiaries ensure that a taxable REIT subsidiary will be subject to an appropriate level of federal income taxation. For example, a taxable REIT subsidiary is limited in its ability to deduct certain interest payments made to an affiliated REIT. In addition, the REIT has to pay a 100% penalty tax on some payments that it receives or on some deductions taken by a taxable REIT subsidiary if the economic arrangements between the

Risks Related to our Debt Financings

​

We face risks related to current debt maturities, including refinancing risk.

​

Certain of our mortgages, bank loans and unsecured debt (including our senior notes) will have significant outstanding balances on their maturity dates, commonly known as “balloon payments.” We may not have the cash resources available to repay those amounts, and we may have to raise funds for such repayment either through the issuance of equity or debt securities, additional bank borrowings (which may include extension of maturity dates), joint ventures or asset sales. Furthermore, we are restricted from incurring certain additional indebtedness and making certain other changes to our capital and debt structure under the terms of the Credit Facility (defined below) and senior notes and the indentures governing the Credit Facility and senior notes.

​

​Table of Contents

Our organizational documents contain no limitation on the amount of debt we may incur. As a result, we may become highly leveraged in the future.

​

Our organizational documents do not limit the amount of indebtedness that we may incur. We could alter the balance between our total outstanding indebtedness and the value of our assets at any time. If we become more highly leveraged, then the resulting increase in debt service could adversely affect our ability to make payments on our outstanding indebtedness and to pay our anticipated distributions and/or the distributions required to maintain our REIT status, and could harm our financial condition.

We have opted out of these provisions of Maryland law. However, our Board may opt to make these provisions applicable to us at any time without shareholder notice or approval.

​

Our Trustees also have the discretion, granted in our bylaws and Maryland law, without shareholder approval to, among other things (1) create a staggered Board, (2) amend our bylaws or repeal individual bylaws in a manner that provides the Board with greater authority, and (3) issue additional equity securities. Any such action could inhibit or impede a third party from making a proposal to acquire us at a price that could be beneficial to our shareholders.

The United States Federal Reserve Board and similar international bodies have increased interest rates in recent years to control and decrease the level of inflation. Such increases in interest rates could have a material effect on our financial performance, as further described under the heading “The terms and covenants relating to our indebtedness could adversely impact our financial performance.”

​

We cannot assure our ability to pay dividends in the future.

​

Historically, we have paid quarterly distributions to our shareholders, and we intend to continue to pay quarterly dividends and to make distributions to our shareholders in amounts such that all or substantially all of our taxable income in each year, subject to certain adjustments, is distributed. This, along with other factors, should enable us to continue to qualify for the tax benefits accorded to a REIT under the Internal Revenue Code. We have not established a minimum dividends payment level, and all future distributions will be made at the discretion of our Board. Our ability to pay dividends will depend upon, among other factors:

Privacy concerns could result in regulatory changes that may harm our business.

​

Personal privacy has become a significant issue in the jurisdictions in which we operate. Many jurisdictions in which we operate, including California and New York, have imposed restrictions and requirements on the use of personal information by those collecting such information. The regulatory framework for privacy issues is rapidly evolving and future enactment of more restrictive laws, rules or regulations and/or future enforcement actions or investigations could have a materially adverse impact on us through increased costs or restrictions on our business. Failure to comply with such laws and regulations could result in consent orders or regulatory penalties and significant legal liability, including fines, which could damage our reputation and have an adverse effect on our results of operations or financial condition.

​

Terrorist attacks, active shooter incidents and other acts of violence or war may adversely impact our performance and may affect the markets on which our securities are traded.

​

Terrorist attacks at or against our stores, our interests or the United States, may negatively impact our operations and the value of our securities. Attacks, armed conflicts or active-shooter situations could negatively impact the demand for self-storage and increase the cost
