Statements Regarding Forward-Looking Information
Certain information set forth in this report contains “forward-looking statements” within the meaning of the federal securities laws. Forward-looking statements include statements concerning our plans, objectives, goals, strategies, future events, future revenues or performance, capital expenditures, financing needs, plans or intentions relating to acquisitions and other information that is not historical information. In some cases, forward-looking statements can be identified by terminology such as “believes,” “expects,” “estimates,” “may,” “will,” “should,” “anticipates,” or “intends” or the negative of such terms or other comparable terminology, or by discussions of strategy. We may also make additional forward-looking statements from time to time. All such subsequent forward-looking statements, whether written or oral, by us or on our behalf, are also expressly qualified by these cautionary statements.
All forward-looking statements, including without limitation, management’s examination of historical operating trends and estimates of future earnings, are based upon our current expectations and various assumptions. Our expectations, beliefs and projections are expressed in good faith and we believe there is a reasonable basis for them, but there can be no assurance that management’s expectations, beliefs and projections will result or be achieved. All forward-looking statements apply only as of the date made.

PART I
Item 1.     Business
General
Extra Space Storage Inc. (“we,” “our,” “us” or the “Company”) is a fully integrated, self-administered and self-managed real estate investment trust (“REIT”) formed as a Maryland corporation on April 30, 2004, to own, operate, manage, acquire, develop and redevelop self-storage properties (“stores”). We closed our initial public offering (“IPO”) on August 17, 2004. Our common stock is traded on the New York Stock Exchange under the symbol “EXR.”
We were formed to continue the business of Extra Space Storage LLC and its subsidiaries, which had engaged in the self-storage business since 1977. These companies were reorganized after the consummation of our IPO and various formation transactions. As of December 31, 2021 we owned and/or operated 2,096 stores in 41 states, and Washington, D.C., comprising approximately 160.9 million square feet of net rentable space in approximately 1.5 million units.
We operate in two distinct segments: (1) self-storage operations; and (2) tenant reinsurance. Our self-storage operations activities include rental operations of wholly-owned stores. Tenant reinsurance activities include the reinsurance of risks relating to the loss of goods stored by tenants in our stores. For more information and comparative financial and other information on our reportable business segments, refer to the segment information footnote in the notes to the consolidated financial statements in Item 8 of this Form 10-K.
Substantially all of our business is conducted through Extra Space Storage LP (the “Operating Partnership”). Our primary assets are general partner and limited partner interests in the Operating Partnership. This structure is commonly referred to as an umbrella partnership REIT, or UPREIT. We have elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”). To the extent we continue to qualify as a REIT we will not be subject to U.S. federal tax, with certain exceptions, on our REIT taxable income that is distributed to our stockholders.
We file our annual report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, and all amendments to those reports with the Securities and Exchange Commission (the “SEC”). You may obtain copies of these documents by visiting the SEC’s website at www.sec.gov. In addition, as soon as reasonably practicable after such materials are furnished to the SEC, we make copies of these documents available to the public free of charge through our website at www.extraspace.com, or by contacting our Secretary at our principal offices, which are located at 2795 East Cottonwood Parkway, Suite 300, Salt Lake City, Utah 84121, telephone number (801) 365-4600.
Management
Members of our executive management team have significant experience in all aspects of the self-storage industry. Our executive management team and their years of industry experience are as follows: Joseph D. Margolis, Chief Executive Officer, 17 years; Scott Stubbs, Executive Vice President and Chief Financial Officer, 21 years; Samrat Sondhi, Executive Vice President and Chief Marketing Officer, 19 years; Gwyn McNeal, Executive Vice President and Chief Legal Officer, 16 years; Matt Herrington, Executive Vice President and Chief Operations Officer, 14 years; Noah Springer, Executive Vice President and Chief Strategy and Partnership Officer, 16 years; Zach Dickens, Executive Vice President and Chief Investment Officer, 19 years.
Our executive management team and board of directors have an ownership position in the Company with executive officers and directors owning approximately 2,054,059 shares or 1.5% of our outstanding common stock as of February 22, 2022.
Industry & Competition
Stores offer month-to-month rental of storage space for personal or business use. Tenants typically rent fully enclosed spaces that vary in size and typically range from 5 feet by 5 feet to 20 feet by 20 feet, with an interior height of 8 feet to 12 feet. Tenants have responsibility for moving their items into and out of their units. Stores generally have on-site managers who supervise and run the day-to-day operations, providing tenants with assistance as needed.
Self-storage provides a convenient way for individuals and businesses to store their possessions due to life changes, or simply because of a need for storage space. The mix of residential tenants using a store is determined by a store’s local demographics and often includes people who are experiencing life changes such as downsizing their living space or others who
4



are not yet settled into a permanent residence. Items that tenants place in self-storage are typically furniture, household items and appliances. Commercial tenants tend to include small business owners who require easy and frequent access to their goods, records, inventory or storage for seasonal goods.
Our research has shown that tenants choose a store based primarily on the convenience of the site to their home or business, making high-density, high-traffic population centers ideal locations for stores. A store’s visibility on the internet, price, perceived security, cleanliness, and the general professionalism of the store managers and staff are also contributing factors to a store’s ability to successfully secure rentals. Although most stores are leased to tenants on a month-to-month basis, tenants tend to continue their leases for extended periods of time.
The self-storage business is subject to seasonal fluctuations. A greater portion of revenues and profits are typically realized from May through September. Historically, our highest level of occupancy has been at the end of July, while our lowest level of occupancy has been in late February and early March.
The self-storage industry is a mature industry that has seen the average occupancy continue to increase. According to the Self-Storage Almanac (the “Almanac”), the national average physical occupancy rate was 90.2% of net rentable square feet in 2015, compared to an average physical occupancy rate of 94.5% in 2021. Our average occupancy for wholly-owned stores for 2021 was 94.8%.
The industry is also characterized by fragmented ownership. According to the Almanac, as of the end of 2021, the top ten self-storage companies in the United States operated approximately 21.9% of the total U.S. stores, and the top 50 self-storage companies operated approximately 27.9% of the total U.S. stores. We believe this fragmentation will contribute to continued consolidation at some level in the future.
We believe that we are well positioned to compete for acquisitions. We have encountered competition when we have sought to acquire existing operating stores, especially for brokered portfolios. Competitive bidding practices have been commonplace between both public and private entities, and this will likely continue.
We are the second largest self-storage operator in the United States. Our four primary competitors who are public self-storage REITs are CubeSmart, Life Storage, National Storage Affiliates and Public Storage.
Long-Term Growth and Investment Strategies
Our primary business objectives are to maximize cash flow available for distribution to our stockholders and to achieve sustainable long-term growth in cash flow per share in order to maximize long-term stockholder value both at acceptable levels of risk. We continue to evaluate a range of growth initiatives and opportunities. Our primary strategies include the following:
Maximize the performance of our stores through strategic, efficient and proactive management
We pursue revenue-generating and expense-minimizing opportunities in our operations. Our revenue management team seeks to maximize revenue by responding to changing market conditions through our advanced technology systems' ability to provide real-time, interactive rental rate and discount management. Our size allows us greater ability than the majority of our competitors to implement more effective online marketing programs, which we believe will attract more customers to our stores at a lower net cost.
We continually analyze our portfolio to look for long-term value-enhancing opportunities. We proactively redevelop properties to add units or modify existing unit mix to better meet the demand in a given market and to maximize revenue. We also redevelop properties to reduce their effective useful age, increase visual appeal, enhance security and to improve brand consistency across the portfolio.
Acquire self-storage stores
Our acquisitions team continues to pursue the acquisition of multi-store portfolios and single stores which can range from fully occupied to various stages of lease-up that we believe can provide stockholder value. We have established a reputation as a reliable, ethical buyer, which we believe enhances our ability to negotiate and close acquisitions. In addition, we believe our status as an UPREIT enables flexibility when structuring deals. We remain a disciplined buyer and only execute acquisitions that we believe will strengthen our portfolio and increase stockholder value.
In addition to the pursuit of operating stores, from time to time we develop stores from the ground up and provide the construction capital. We also purchase stores at the completion of construction from third party developers, who build to our specifications. These stores purchased at completion of construction (a "Certificate of Occupancy store"), create additional
5



long-term value for our stockholders. We are typically able to acquire these assets at a lower price than a stabilized store, and expect greater long term returns on these stores on average. However, in the short term, these acquisitions cause dilution to our earnings during the two-to-four year period required to lease up the Certificate of Occupancy stores. We expect that this trend will continue as we continue to acquire Certificate of Occupancy stores.
Grow our management business
Our management business enables us to generate increased revenues through management fees as well as expand our geographic footprint, data sophistication and scale with little capital investment. We believe this expanded footprint enables us to reduce our operating costs through economies of scale. In addition, we see our management business as a future acquisition pipeline. We pursue strategic relationships with owners whose stores would enhance our portfolio in the event an opportunity arises to acquire such stores.
Expand our bridge loan program
To broaden the opportunities available, we have a bridge lending program, under which we provide financing to operating properties that we manage.  This program helps us increase our management business, create additional future acquisition opportunities, and strengthen our relationships with partners, all while generating interest and fee income. We generally originate mortgage loans and mezzanine loans, with the intent to sell many of the mortgage loans to third parties, while retaining our interests in the mezzanine loans.
Invest in other self-storage businesses selectively
We have made investments in preferred stock of other self-storage companies. These investments benefit us by providing dividend income, increasing our management business, and creating additional future acquisition opportunities through relationships with the companies in which we invest. We may pursue additional investment opportunities as they become available.
Financing of Our Long-Term Growth Strategies
Acquisition and Development Financing
As a REIT, we are required to distribute at least 90% of our REIT taxable income to our stockholders. Consequently, we require access to additional sources of capital to fund our growth. We expect to maintain a flexible approach to financing growth. We plan to finance future acquisitions through a diverse capital optimization strategy which includes but is not limited to: cash generated from operations, borrowings under our revolving lines of credit (the "Credit Lines"), secured and unsecured financing, equity offerings, joint ventures and the sale of stores.
Credit Lines - We have two credit lines which we primarily use as short-term bridge financing until we obtain longer-term financing through either debt or equity. As of December 31, 2021, our Credit Lines had available capacity of $1.4 billion, of which $855.0 million was undrawn.
Secured and Unsecured Debt - We primarily use public bonds, unsecured private placement bonds and unsecured bank term loans to finance store acquisitions and development efforts. We will continue to utilize a combination of secured and unsecured financing for future store acquisitions and development. As of December 31, 2021, we had $1.3 billion of secured notes payable and $4.1 billion of unsecured notes payable outstanding compared to $2.2 billion of secured notes payable and $3.2 billion of unsecured notes payable and senior exchangeable notes outstanding as of December 31, 2020.
Equity - We have an active "at the market" ("ATM") program for selling stock. We sell stock under the ATM program from time to time to raise capital when we believe conditions are advantageous. During the year ended December 31, 2021, we issued 585,685 shares of common stock through our ATM program and received net proceeds of approximately $66.6 million. We also sold 1,600,000 shares of common stock in a registered offering structured as a bought deal at a price of $129.13 per share resulting in net proceeds of $206.6 million. During the year ended December 31, 2020, we issued 899,048 shares of common stock through our ATM program and received net proceeds of approximately $103.5 million.
We view equity interests in our Operating Partnership as another source of capital that can provide an attractive tax planning opportunity to sellers of real estate. We issue common and preferred Operating Partnership units to sellers in certain acquisitions. Common Operating Partnership units receive distributions equal to the dividends on common stock, while Preferred Operating Partnership units receive distributions at various negotiated rates. We may issue additional units in the future when circumstances are favorable.
6



Joint Ventures - As of December 31, 2021, we owned 287 of our stores through joint ventures with third parties. Our joint venture partners typically provide most of the equity capital required for the acquisition of stores owned in these joint ventures. Most joint venture agreements include buy-sell rights, as well as rights of first offer in connection with the sale of stores by the joint venture. We manage the day-to-day operations of the stores owned in these joint ventures and have the right to participate in major decisions relating to sales of stores or financings by the applicable joint venture, but do not control the joint ventures.
Sale of Properties - We have not historically sold a high volume of stores, as we generally believe we are able to optimize the cash flow from stores through continued operations. However, we may sell more stores or interests in stores in the future in response to changing economic, financial or investment conditions. For the year ended December 31, 2021, we sold 16 stores for $200.3 million. For the year ended December 31, 2020, we sold four stores located in Florida for $46.6 million. For the year ended December 31, 2019, we sold one store located in New York for $11.3 million.
Regulation
Generally, stores are subject to various laws, ordinances and regulations, including regulations relating to lien sale rights and procedures and the Americans with Disabilities Act of 1990. Changes in any of these laws or regulations, as well as changes in laws, such as the Comprehensive Environmental Response and Compensation Liability Act, which increase the potential liability for environmental conditions or circumstances existing or created by tenants or others on stores, or laws affecting development, construction, operation, upkeep, safety and taxation may result in significant unanticipated expenditures, loss of stores or other impairments to operations, which would adversely affect our financial position, results of operations or cash flows. In addition, noncompliance with any of these laws, ordinances or regulations could result in the imposition of fines or an award of damages to private litigants and also could require substantial capital expenditures to ensure compliance.
Insurance activities are subject to state insurance laws and regulations as determined by the particular insurance commissioner for each state in accordance with the McCarran-Ferguson Act, and are subject to the Gramm-Leach-Bliley Act and the privacy regulations promulgated by the Federal Trade Commission pursuant thereto. Store management activities may be subject to state real estate brokerage laws and regulations as determined by the particular real estate commission for each state. Our collection and processing of personal information may be subject to various data privacy and security laws, which govern the collection, use, disclosure of personal information and are constantly evolving, may conflict with each other to complicate compliance efforts and can results in investigations, proceedings, or actions that lead to significant civil and/or criminal penalties and restrictions on data processing. Changes in any of the laws governing our conduct could have an adverse impact on our ability to conduct our business or could materially affect our financial position, results of operations or cash flows.

Human Capital

At Extra Space, our culture is driven by our belief that our people are a key driver in our success. We believe that if we focus on attracting, developing, and retaining diverse top talent at all levels of the organization, our employees will take care of our customers and drive growth for our shareholders.

As of December 31, 2021, we had 4,309 employees and believe our relationship with our employees is good. Our employees are not represented by a collective bargaining agreement. In 2021, we invited our employees to participate in an employee satisfaction survey. We achieved an overall satisfaction score of 74% with over 78% of our employees participating in our survey.

Compensation, Health and Well Being

The Company offers competitive health benefits and encourages its employees to participate in employee health and wellness programs. Over 60% of our employees who are enrolled in our health plan participate in these programs. We offer individualized counseling to our employees to assist them with their journey towards better health. We also offer other health-oriented benefits such as smoking cessation programs and a fitness program that allows for reimbursements to employees for expenses incurred relating to fit-friendly activities, sports or exercise equipment.

Training and Development

In order to attract and retain diverse top talent, we offer training and development opportunities for our employees. In 2021, we invested in training and development for our employees, which included leadership training, communication training,
7



individual learning plans, site manager training and mentorship programs. Our field employees received on average 8 hours of training in 2021 and each new hire received an average of 82 hours of training in 2021. Additionally, the Company provides its employees with an education assistance program through Western Governors University that allows our employees a path to an undergraduate degree in business or information technology through scholarships and other assistance.

The Company has always valued the safety of our employees and provides regular training for our employees to increase safety at our sites. During 2021, we continued to make masks and other protective equipment available to our employees. We also paid out more than $500,000 to employees in an effort to encourage our employees to get vaccinated against COVID-19. In addition, we paid out more than $380,000 in relief pay to our employees who were unable to work due to testing positive for COVID-19.

Diversity and Inclusion

The Company values diversity and inclusion and undertakes a wide spectrum of initiatives to attract and retain a diverse workforce. During 2021, the Company launched four employee resource groups that provide our employees a space to build community by celebrating their culture, providing mentoring opportunities and developing educational content for Extra Space. The Company will continue to implement and pursue diversity and inclusion initiatives and goals that allow us to attract and retain top talent, improve employee engagement, increase innovation and customer insight and enhance the quality of our decision making. Forbes Magazine recently named the Company as a Best Employer for Diversity in 2020.

Our employee population is approximately 48% female and approximately 48% have self-identified as people of color: Black or African American (16%), Hispanic or Latino (21%), Asian (3%), of two or more races (4%), Native American (0.5%), and Pacific Islander (0.5%).

We believe that our emphasis on training and development, employee safety, employee health and well-being, and a commitment to diversity and inclusion leads to an increase in employee productivity and positions us to attract and retain top diverse talent.
Item 1A.     Risk Factors
An investment in our securities involves various risks. All investors should carefully consider the following risk factors in conjunction with the other information contained in this Annual Report before trading in our securities. If any of the events set forth in the following risks actually occur, our business, operating results, prospects and financial condition could be harmed.
Our performance is subject to risks associated with real estate investments. We are a real estate company that derives our income from the operation of our stores. There are a number of factors that may adversely affect the income that our stores generate, including the following:
Risks Related to Our Stores and Operations
Adverse economic or other conditions in the markets in which we do business could negatively affect our occupancy levels and rental rates and therefore our operating results.
Our revenues and net operating income can be negatively impacted by general economic factors that lead to a reduction in demand for rental space in the markets in which we operate.
If we are unable to promptly re-let our units or if the rates upon such re-letting are significantly lower than expected, our business and results of operations would be adversely affected.
Virtually all of our leases are on a month-to-month basis. Any delay in re-letting units as vacancies arise would reduce our revenues and harm our operating results. In addition, lower than expected rental rates upon re-letting could adversely affect our revenues and impede our growth.
8



Uninsured losses or losses in excess of our insurance coverage could adversely affect our financial condition and our cash flow.
We maintain comprehensive property and casualty insurance policies, including liability, fire, flood, earthquake, wind (as we deem necessary or as required by our lenders), umbrella coverage and rental loss insurance with respect to our stores. Certain types of losses, however, may be either uninsurable, not economically insurable, or coverage may be excluded on certain policies, such as losses due to earthquakes, hurricanes, tornadoes, riots, acts of war, terrorism, or social engineering. Should an uninsured loss occur, we could lose both our investment in and anticipated profits and cash flow from a store. In addition, if any such loss is insured, we may be required to pay significant amounts on any claim for recovery of such a loss prior to our insurer being obligated to reimburse us for the loss, or the amount of the loss may exceed our coverage for the loss. As a result, our operating results may be adversely affected.
Legal disputes, settlement and defense costs could have an adverse effect on our operating results.
From time to time we have to make monetary settlements or defend actions or arbitration (including class actions) to resolve tenant, employment-related or other claims and disputes. Settling any such liabilities could negatively impact our operating results and cash available for distribution to stockholders, and could also adversely affect our ability to sell, lease, operate or encumber affected properties.
Our tenant reinsurance business is subject to significant governmental regulation, which may adversely affect our results.
Our tenant reinsurance business is subject to significant governmental regulation. The regulatory authorities generally have broad discretion to grant, renew and revoke licenses and approvals, to promulgate, interpret and implement regulations, and to evaluate compliance with regulations through periodic examinations, audits and investigations of the affairs of insurance providers. As a result of regulatory or private action in any jurisdiction, we may be temporarily or permanently suspended from continuing some or all of our reinsurance activities, or otherwise fined or penalized or suffer an adverse judgment, which could adversely affect our business and results of operations.
Environmental compliance costs and liabilities associated with operating our stores may adversely affect our results of operations.
Under various U.S. federal, state and local laws, ordinances and regulations, a current or previous owner, developer or operator of real estate may be liable for the costs of removal or remediation of certain hazardous or toxic substances, which could be substantial. Such laws often impose liability without regard to whether the owner or operator knew of, or was responsible for, the release or presence of such hazardous substances. From time to time, we may acquire properties, or interests in properties, with known adverse environmental conditions for which we believe that the environmental liabilities associated with these conditions are quantifiable and that the acquisition will yield a superior risk-adjusted return.
Costs associated with complying with the Americans with Disabilities Act of 1990 may result in unanticipated expenses.

Under the ADA, places of public accommodation are required to meet certain federal requirements related to access and use by disabled persons. A number of additional U.S. federal, state and local laws may also require modifications to our stores, or restrict certain further renovations of the stores, with respect to access thereto by disabled persons. If one or more of our stores is not in compliance with the ADA or other legislation, then we would be required to incur additional costs to bring the facility into compliance.
There is significant competition among self-storage operators and from other storage alternatives.
Competition in the local markets in which many of our stores are located is significant and has affected our occupancy levels, rental rates and operating expenses. Development of self-storage facilities has increased in recent years, which has intensified competition, and we expect it will continue to do so as newly developed facilities are opened. Development of self-storage facilities by other operators could continue to increase in the future. Actions by our competitors may decrease or prevent increases in our occupancy and rental rates, while increasing our operating expenses, which could adversely affect our business and results of operations.
We may not be successful in identifying and consummating suitable acquisitions that meet our criteria, which may impede our growth.
Our ability to expand through acquisitions is integral to our business strategy and requires us to identify suitable acquisition candidates or investment opportunities that meet our criteria and are compatible with our growth strategy. We may not be successful in identifying suitable stores or other assets that meet our acquisition criteria or in consummating acquisitions
9



or investments on satisfactory terms or at all. Failure to identify or consummate acquisitions will slow our growth, which could in turn adversely affect our stock price.
Our ability to acquire stores on favorable terms and successfully integrate and operate them may be constrained by the following significant risks

competition from local investors and other real estate investors with significant capital, including other publicly-traded REITs and institutional investment funds;
competition from other potential acquirers may significantly increase the purchase price which could reduce our profitability;
the inability to achieve satisfactory completion of due diligence investigations and other customary closing conditions; and
we may acquire stores subject to liabilities without any recourse, or with only limited recourse, with respect to unknown liabilities such as liabilities for clean-up of undisclosed environmental contamination, claims by persons dealing with the former owners of the stores and claims for indemnification by general partners, directors, officers and others indemnified by the former owners of the stores.
We and our vendors rely on information technology, and any material failure, inadequacy, interruption or security failure of that technology could harm our business.
We rely on information technology networks and systems, including the Internet, to process, transmit and store electronic information, and to manage or support a variety of business processes, including financial transactions and records, personally identifiable information, and tenant and lease data. We purchase some of our information technology from vendors, on whom our systems depend. We rely on commercially available systems, software, tools and monitoring to provide security for processing, transmission and storage of confidential tenant and other sensitive information. Our information technology systems and those of our third-party service providers, strategic partners and other contractors or consultants are vulnerable to attack and damage or interruption from computer viruses and malware (e.g. ransomware), malicious code, natural disasters, terrorism, war, telecommunication and electrical failures, hacking, cyberattacks, phishing attacks and other social engineering schemes, employee theft or misuse, human error (e.g., social engineering, phishing), fraud, denial or degradation of service attacks, sophisticated nation-state and nation-state-supported actors or unauthorized access or use by persons inside our organization, or persons with access to systems inside our organization. Although we have taken steps to protect the security of our information systems and the data maintained in those systems, it is possible that our safety and security measures will not be able to prevent the systems’ improper functioning or damage, or the improper access or disclosure of personally identifiable information such as in the event of cyber-attacks. Security breaches, including physical or electronic break-ins, computer viruses, attacks by hackers and similar breaches, can create system disruptions, shutdowns or unauthorized disclosure of confidential information.
We and certain of our service providers are from time to time, subject to cyberattacks and security incidents. While to date, we have not experienced a material security breach, this risk has generally increased as the number, intensity and sophistication of such breaches and attempted breaches from around the world have increased. Furthermore, because the technologies used to obtain unauthorized access to, or to sabotage or disrupt, systems change frequently and often are not recognized until launched against a target, we may be unable to anticipate these techniques or implement adequate preventative measures. We may also experience security breaches that may remain undetected for an extended period. Even if identified, we may be unable to adequately investigate or remediate incidents or breaches due to attackers increasingly using tools and techniques that are designed to circumvent controls, to avoid detection, and to remove or obfuscate forensic evidence. As a result of the COVID-19 pandemic, we may also face increased cybersecurity risks due to our reliance on internet technology and the number of our, as well as our service providers’, employees who are (and may continue to be) working remotely, which may create additional opportunities for cybercriminals to exploit vulnerabilities. Any failure to maintain proper function, security and availability of our information systems could interrupt our operations, damage our reputation, divert significant management attention and resources to remedy any damages that result, subject us to liability claims or regulatory penalties and have a material adverse effect on our business and results of operations.

Failure to comply with laws and regulations relating to data privacy and protection, could adversely affect our business and our financial condition.

In the United States, both federal and various state governments have adopted, or are considering, laws, guidelines or rules for the collection, distribution, use and storage of information collected from or about consumers or their devices. For example, the California Consumer Privacy Act of 2018 (CCPA) went into effect on January 1, 2020, and creates individual privacy rights for California consumers and increases the privacy and security obligations of entities handling certain personal information. The CCPA provides for civil penalties for violations, as well as a private right of action for data breaches that is expected to increase data breach litigation. Further, the California Privacy Rights Act (CPRA) recently passed in California. The CPRA significantly
10



amends the CCPA and will impose additional data protection obligations on covered businesses, including additional consumer rights processes, limitations on data uses, new audit requirements for higher risk data, and opt outs for certain uses of sensitive data. It will also create a new California data protection agency authorized to issue substantive regulations and could result in increased privacy and information security enforcement. The majority of the provisions will go into effect on January 1, 2023, and additional compliance investment and potential business process changes may be required. Similar laws have passed in Virginia and Colorado, and have been proposed in other states and at the federal level, reflecting a trend toward more stringent privacy legislation in the United States. The enactment of such laws could have potentially conflicting requirements that would make compliance challenging.

Although we work to comply with applicable laws, regulations and standards, our contractual obligations and other legal obligations, these requirements are evolving and may be modified, interpreted and applied in an inconsistent manner from one jurisdiction to another, and may conflict with one another or other legal obligations with which we must comply. Any failure or perceived failure by us or our employees, representatives, contractors, consultants, collaborators, or other third parties to comply with such requirements or adequately address privacy and security concerns, even if unfounded, could result in additional cost and liability to us, damage our reputation, and adversely affect our business and results of operations.

Our property taxes could increase due to reassessment or property tax rate changes.
Real property taxes on our properties may increase as our properties are reassessed by taxing authorities or as property tax rates change. Therefore, the amount of property taxes we are required to pay could increase substantially from the property taxes we currently pay or have paid in the past, including on a retroactive basis. If our property taxes we pay increase, our cash flow would be adversely impacted, and our ability to pay any expected dividends to our stockholders and unitholders could be adversely affected.
The COVID-19 pandemic or other pandemics could adversely affect our results of operations.

During 2021, the United States and other countries around the world have continued to experience a major health pandemic related to COVID-19, which has created considerable instability and disruption in the U.S. and world economies. Governmental authorities in impacted regions are taking varied and sometimes dramatic action in an effort to slow the spread of COVID-19. In 2020, federal, state and local jurisdictions issued varying forms of states of emergency orders. While many of these states of emergency orders have expired or been removed, we continue to monitor existing states of emergency and prepare for any additional states of emergency orders. We have updated many of our safety and working practices so that we are prepared to address any future states of emergency orders should they continue or be reinstated.

Our business was impacted by COVID-19 in 2020 in several ways, including reductions in new rentals and vacates due to stay-at home orders and other restrictions, lower achieved rental rates from new customers, fewer existing customer rent increases, reduced late fee collection and impaired ability to hold auctions resulting in higher accounts receivable and bad debt. During 2021 we largely saw a return toward normalcy, including higher achieved rates, accounts receivable and collections less than 60 days returning to historical norms, and auctions being held in most locations. As a result of the reductions in vacates, we saw record occupancy levels during 2021.
Although the self-storage industry has historically been resilient to ordinary market downturns, the impact of the COVID-19 pandemic on the U.S. and world economies generally, and on our future results in particular, could be significant and will largely depend on future developments, which are highly uncertain and cannot be predicted. This includes new information which may emerge concerning the severity of COVID-19 variants, the success of actions taken to contain or treat COVID-19 and reactions by consumers, companies, governmental entities and capital markets.

Risks Related to Our Organization and Structure
Conflicts of interest could arise as a result of our relationship with our Operating Partnership.
Conflicts of interest could arise in the future as a result of the relationships between us and our affiliates, and our Operating Partnership or any partner thereof. Our directors and officers have duties to our Company under applicable Maryland law in connection with their management of our Company. At the same time, we, through our wholly-owned subsidiary, have fiduciary duties, as a general partner, to our Operating Partnership and to the limited partners under Delaware law in connection with the management of our Operating Partnership. Our duties, through our wholly-owned subsidiary, as a general partner to our Operating Partnership and its partners may come into conflict with the duties of our directors and officers to our Company. The partnership agreement of our Operating Partnership does not require us to resolve such conflicts in favor of either our Company or the limited partners in our Operating Partnership. Unless otherwise provided for in the relevant partnership agreement, Delaware law generally requires a general partner of a Delaware limited partnership to adhere to fiduciary duty standards under which it owes its limited partners the highest duties of good faith, fairness, and loyalty and which generally prohibit such general partner from taking any action or engaging in any transaction as to which it has a conflict of interest.
Additionally, the partnership agreement expressly limits our liability by providing that neither we, our direct wholly-owned Massachusetts business trust subsidiary, as the general partner of the Operating Partnership, nor any of our or their trustees, directors or officers, will be liable or accountable in damages to our Operating Partnership, the limited partners or assignees for errors in judgment, mistakes of fact or law or for any act or omission if we, or such trustee, director or officer, acted in good faith. In addition, our Operating Partnership is required to indemnify us, our affiliates and each of our respective trustees, officers, directors, employees and agents to the fullest extent permitted by applicable law against any and all losses, claims, damages, liabilities (whether joint or several), expenses (including, without limitation, attorneys’ fees and other legal fees and expenses), judgments, fines, settlements and other amounts arising from any and all claims, demands, actions, suits or proceedings, civil, criminal, administrative or investigative, that relate to the operations of the Operating Partnership, provided that our Operating Partnership will not indemnify for (1) willful misconduct or a knowing violation of the law, (2) any transaction for which such person received an improper personal benefit in violation or breach of any provision of the partnership agreement, or (3) in the case of a criminal proceeding, the person had reasonable cause to believe the act or omission was unlawful.

The provisions of Delaware law that allow the common law fiduciary duties of a general partner to be modified by a partnership agreement have not been resolved in a court of law, and we have not obtained an opinion of counsel covering the provisions set forth in the partnership agreement that purport to waive or restrict our fiduciary duties that would be in effect under common law were it not for the partnership agreement.
Our joint venture investments could be adversely affected by our lack of sole decision-making authority.
As of December 31, 2021, we held interests in 287 operating stores through joint ventures. Some of these arrangements could be adversely affected by our lack of sole decision-making authority, our reliance on co-venturers' financial conditions and disputes between us and our co-venturers. We expect to continue our joint venture strategy by entering into more joint ventures for the purpose of developing new stores and acquiring existing stores. In such event, we would not be in a position to exercise sole decision-making authority regarding the property, partnership, joint venture or other entity. The decision-making authority regarding the stores we currently hold through joint ventures is either vested exclusively with our joint venture partners, is subject to a majority vote of the joint venture partners or is equally shared by us and the joint venture partners. In addition, investments in partnerships, joint ventures or other entities may, under certain circumstances, involve risks not present were a third party not involved, including the possibility that partners or co-venturers might become bankrupt or fail to fund their share of required capital contributions. Partners or co-venturers may have economic or other business interests or goals which 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 may also have the potential risk of impasses on decisions, such as a sale, because neither we nor the partner or co-venturer would have full control over the partnership or joint venture. Disputes between us and partners or co-venturers may result in litigation or arbitration that would increase our expenses and prevent our officers and/or directors from focusing their time and efforts on our business. Consequently, actions by or disputes with partners or co-venturers might result in subjecting stores owned by the partnership or joint venture to additional risk. In addition, we may in certain circumstances be liable for the actions of our third-party partners or co-venturers, which could harm our financial condition.
Certain provisions of Maryland law and our organizational documents, including the stock ownership limit imposed by our charter, may inhibit market activity in our stock and could prevent or delay a change in control transaction.
Our charter, subject to certain exceptions, authorizes our directors to take such actions as are necessary and desirable to preserve our qualification as a REIT and to limit any person to actual or constructive ownership of no more than 7.0% (by value
12



or by number of shares, whichever is more restrictive) of our outstanding common stock or 7.0% (by value or by number of shares, whichever is more restrictive) of our outstanding capital stock. Our board of directors, in its sole discretion, may exempt a proposed transferee from the ownership limit. However, our board of directors may not grant an exemption from the ownership limit to any proposed transferee whose ownership could jeopardize our qualification as a REIT. These restrictions on ownership will not apply if our board of directors determines that it is no longer in our best interests to attempt to qualify, or to continue to qualify, as a REIT. The ownership limit may delay or impede a transaction or a change of control that might involve a premium price for our securities or otherwise be in the best interests of our stockholders. Different ownership limits apply to the family of Kenneth M. Woolley, certain of his affiliates, family members and estates and trusts formed for the benefit of the foregoing; to Spencer F. Kirk, certain of his affiliates, family members and estates and trusts formed for the benefit of the foregoing; and to certain designated investment entities as defined in our charter.
Our board of directors has the power to issue additional shares of our stock in a manner that may not be in the best interest of our stockholders.
Our charter authorizes our board of directors to issue additional authorized but unissued shares of common stock or preferred stock and to increase the aggregate number of authorized shares or the number of shares of any class or series without stockholder approval. In addition, our board of directors may classify or reclassify any unissued shares of common stock or preferred stock and set the preferences, rights and other terms of the classified or reclassified shares. Our board of directors could issue additional shares of our common stock or establish a series of preferred stock that could have the effect of delaying, deferring or preventing a change in control or other transaction that might involve a premium price for our securities or otherwise not be in the best interests of our stockholders.
Our rights and the rights of our stockholders to take action against our directors and officers are limited.
Maryland law provides that a director or officer has no liability in that capacity if he or she performs his or her duties in good faith, in a manner he or she reasonably believes to be in our best interests and with the care that an ordinarily prudent person in a like position would use under similar circumstances. In addition, our charter eliminates our directors’ and officers’ liability to us and our stockholders for money damages except for liability resulting from actual receipt of an improper benefit in money, property or services or active and deliberate dishonesty established by a final judgment and which is material to the cause of action. Our bylaws require us to indemnify our directors and officers for liability resulting from actions taken by them in those capacities to the maximum extent permitted by Maryland law. As a result, we and our stockholders may have more limited rights against our directors and officers than might otherwise exist under common law. In addition, we may be obligated to fund the defense costs incurred by our directors and officers.
Risks Related to Our Debt Financings
Disruptions in the financial markets could affect our ability to obtain debt financing on reasonable terms and have other adverse effects on us.
Uncertainty in the credit markets may negatively impact our ability to access additional debt financing or to refinance existing debt maturities on favorable terms (or at all), which may negatively affect our ability to make acquisitions and fund development projects. A downturn in the credit markets may cause us to seek alternative sources of potentially less attractive financing, and may require us to adjust our business plan accordingly. In addition, these factors may make it more difficult for us to sell stores or may adversely affect the price we receive for stores that we do sell, as prospective buyers may experience increased costs of debt financing or difficulties in obtaining debt financing.
Required payments of principal and interest on borrowings may leave us with insufficient cash to operate our stores or to pay the distributions currently contemplated or necessary to maintain our qualification as a REIT and may expose us to the risk of default under our debt obligations.
As of December 31, 2021, we had approximately $6.0 billion of outstanding indebtedness. We may incur additional debt in connection with future acquisitions and development. We may borrow under our Credit Lines or borrow new funds to finance these future stores. Additionally, we do not anticipate that our internally generated cash flow will be adequate to repay our existing indebtedness upon maturity and, therefore, we expect to repay our indebtedness through refinancings and equity and/or debt offerings. Further, we may need to borrow funds in order to make cash distributions to maintain our qualification as a REIT or to make our expected distributions. To qualify as a REIT, we generally must distribute to our stockholders at least 90% of our REIT taxable income each year, determined without regard to the dividends paid deduction and excluding net capital gains, and we are subject to U.S. federal corporate income tax to the extent that we distribute less than 100% of our REIT taxable income each year, determined without regard to the deduction for dividends paid and including net capital gains.
13



If we are required to utilize our Credit Lines for purposes other than acquisition activity, this will reduce the amount available for acquisitions and could slow our growth. Therefore, our level of debt and the limitations imposed on us by our debt agreements could have significant adverse consequences, including the following:
our cash flow may be insufficient to meet our required principal and interest payments;
we may be unable to borrow additional funds as needed or on favorable terms, including to make acquisitions or to continue to make distributions required to maintain our qualification as a REIT;
we may be unable to refinance our indebtedness at maturity or the refinancing terms may be less favorable than the terms of our original indebtedness;
because a portion of our debt bears interest at variable rates, an increase in interest rates could materially increase our interest expense;
we may be forced to dispose of one or more of our stores, possibly on disadvantageous terms;
after debt service, the amount available for cash distributions to our stockholders is reduced;
we may experience increased vulnerability to economic and industry downturns, reducing our ability to respond to changing business and economic conditions;
we may default on our obligations and the lenders or mortgagees may foreclose on our stores that secure their loans and receive an assignment of rents and leases and/or enforce our guarantees;
we may violate restrictive covenants in our loan documents, which would entitle the lenders to accelerate our debt obligations; and
our default under any one of our mortgage loans with cross-default or cross-collateralization provisions could result in a default on other indebtedness or result in the foreclosures of other stores.
Increases in interest rates may increase our interest expense and adversely affect our cash flow and our ability to service our indebtedness and make cash distributions to our stockholders.
As of December 31, 2021, we had approximately $6.0 billion of debt outstanding, of which approximately $1.5 billion, or 24.7% was subject to variable interest rates (excluding debt with interest rate swaps). This variable rate debt had a weighted average interest rate of approximately 1.3% per annum. Increases in interest rates on this variable rate debt would increase our interest expense, which could harm our cash flow and our ability to pay cash distributions.
Failure to hedge effectively against interest rate changes may adversely affect our results of operations.
In certain cases we may seek to manage our exposure to interest rate volatility by using interest rate hedging arrangements. Hedging involves risks, such as the risk that the counterparty may fail to honor its obligations under an arrangement. Failure to hedge effectively against interest rate changes may adversely affect our financial condition, results of operations and ability to make cash distributions to our stockholders.
Changes in the method pursuant to which the London Interbank Offered Rate (“LIBOR”) is determined and the transition to other benchmarks may adversely affect our financial results.
LIBOR and certain other “benchmarks” have been the subject of continuing national, international and other regulatory guidance and proposals for reform. In July 2017, the United Kingdom’s Financial Conduct Authority (“FCA”), which regulates LIBOR, publicly announced that it intends to phase out LIBOR, and on March 5, 2021, the FCA announced that USD LIBOR will no longer be provided by any administrator or no longer be representative immediately after December 31, 2021, in the case of one week and two month USD settings, and immediately after June 30, 2023, in the case of the remaining USD settings. Additionally, banking regulators, including the U.S. Federal Reserve, have encouraged banks to discontinue new LIBOR debt issuances after December 31, 2021. This announcement has several implications, including setting the spread that may be used to automatically convert contracts from LIBOR to the Secured Overnight Financing Rate ("SOFR"). SOFR is a measure of the cost of borrowing cash overnight, collateralized by U.S. Treasury securities, and is based on directly observable U.S. Treasury-backed repurchase transactions. Although SOFR appears to be the preferred replacement rate for U.S. dollar LIBOR, it is unclear if other benchmarks may emerge or if other rates will be adopted outside of the United States.
We anticipate that the most commonly used tenors of LIBOR will continue to be available at least until June 30, 2023. Any changes adopted by the FCA or other governing bodies in the method used for determining LIBOR may result in a sudden or prolonged increase or decrease in reported LIBOR. If that were to occur, our interest payments could change. In addition, uncertainty about the extent and manner of future changes may result in interest rates and/or payments that are higher or lower than if LIBOR were to remain available in its current form.
14



We have contracts that are indexed to LIBOR and are monitoring and evaluating the related risks, which include interest on loans and amounts received and paid on derivative instruments. These risks arise in connection with transitioning contracts to an alternative rate, including any resulting value transfer that may occur, and are likely to vary by contract. The value of loans, securities, or derivative instruments tied to LIBOR, as well as interest rates on our current or future indebtedness, may also be impacted if LIBOR is limited or discontinued. For some instruments the method of transitioning to an alternative reference rate may be challenging, especially if we cannot agree with the respective counterparty about how to make the transition.
While we expect LIBOR to be available in substantially its current form until at least the end of June 30, 2023, it is possible that LIBOR will become unavailable prior to that point. This could result, for example, if sufficient banks decline to make submissions to the LIBOR administrator. In that case, the risks associated with the transition to an alternative reference rate will be accelerated and magnified.
Alternative rates and other market changes related to the replacement of LIBOR, including the introduction of financial products and changes in market practices, may lead to risk modeling and valuation challenges, such as adjusting interest rate accrual calculations and building a term structure for an alternative rate.
The introduction of an alternative rate also may create additional basis risk and increased volatility as alternative rates are phased in and utilized in parallel with LIBOR.
Adjustments to systems and mathematical models to properly process and account for alternative rates will be required, which may have a material adverse effect on our financing costs, and as a result, our financial condition, operating results and cash flows.
Our existing indebtedness contains covenants that limit our operating flexibility and failure to comply with all covenants in our debt agreements could materially and adversely affect us.
Our debt agreements, including our credit agreement governing the revolving credit facility and term loans and the indentures governing our public traded notes, contain various financial and other covenants that we and our operating partnership must comply with including total debt to asset ratios, secured debt to total asset ratios, adjusted EBITDA to fixed charged ratios and minimum ratios of unencumbered assets to unsecured debt which we must maintain.
These covenants may limit our operating flexibility and could prevent us from taking advantage of business opportunities as they arise, growing our business or competing effectively. Our ability to meet these covenants may be affected by events beyond our control, and we may be unable to maintain compliance with these covenants. If we fail to meet these requirements, we may be unable to obtain waivers from the lenders or indenture trustee, as applicable, or amend the covenants.
A breach of any of the covenants or other provisions in our debt agreements could result in an event of default, which if not cured or waived, could result in such debt becoming due and payable, either automatically or after an election to accelerate by the required percentage of the holders of the indebtedness or by an agent for the holders of the indebtedness. This, in turn, could cause our other debt, including the notes and our revolving credit facility, to become due and payable as a result of cross-default or cross-acceleration provisions contained in the agreements governing the other debt and permit certain of our lenders to foreclose on our assets, if any, that secure this debt. In the event that some or all of our debt is accelerated and becomes immediately due and payable, we may not have the funds to repay, or the ability to refinance our debt.
Risks Related to Qualification and Operation as a REIT
Dividends payable by REITs may be taxed at higher rates.
Dividends payable by REITs may be taxed at higher rates than dividends of non-REIT corporations. The maximum U.S. federal income tax rate for qualified dividends paid by domestic non-REIT corporations to U.S. stockholders that are individuals, trust or estates is generally 20%. Dividends paid by REITs to such stockholders are generally not eligible for that rate, but under current tax law, such stockholders may deduct up to 20% of ordinary dividends (i.e., dividends not designated as capital gain dividends or qualified dividend income) received from a REIT for taxable years beginning before January 1, 2026. Although this deduction reduces the effective tax rate applicable to certain dividends paid by REITs, such tax rate may still be higher than the tax rate applicable to regular corporate qualified dividends. This may cause investors to view REIT investments as less attractive than investments in non-REIT corporations, which in turn may adversely affect the value of stock of REITs, including our stock. In addition, the relative attractiveness of real estate in general may be adversely affected by the favorable tax treatment given to corporate dividends, which could negatively affect the value of our stores.
15



Possible legislative or other actions affecting REITs could adversely affect our stockholders.
The rules dealing with U.S. federal income taxation are constantly under review by persons involved in the legislative process and by the Internal Revenue Service ("IRS") and the U.S. Department of the Treasury. Changes to the tax laws, with or without retroactive application, could adversely affect our investors or us in ways we cannot predict. New legislation, Treasury Regulations, administrative interpretations or court decisions could significantly and negatively affect our ability to qualify as a REIT, the U.S. federal income tax consequences of such qualification, or the U.S. federal income tax consequences of an investment in us. Also, the law relating to the tax treatment of other entities, or an investment in other entities, could change, making an investment in such other entities more attractive relative to an investment in a REIT.
Our failure to qualify as a REIT would have significant adverse consequences to us and the value of our stock.
We believe we operate in a manner that allows us to qualify as a REIT for U.S. federal income tax purposes under the Internal Revenue Code. If we fail to qualify as a REIT or lose our qualification as a REIT at any time, we will face serious tax consequences that would substantially reduce the funds available for distribution for each of the years involved because:
 
we would not be allowed a deduction for distributions to stockholders in computing our taxable income and would be subject to U.S. federal corporate income tax on our taxable income;
we also could be subject to the U.S. federal alternative minimum income tax for taxable years prior to 2018 and possibly increased state and local taxes; and
unless we are entitled to relief under applicable statutory provisions, we could not elect to be taxed as a REIT for four taxable years following a year during which we were disqualified.
In addition, if we fail to qualify as a REIT, we will not be required to make distributions to stockholders, and all distributions to stockholders will be subject to tax as regular corporate dividends to the extent of our current and accumulated earnings and profits. This means that our U.S. individual stockholders would be taxed on our dividends at capital gains rates, and our U.S. corporate stockholders would be entitled to the dividends received deduction with respect to such dividends, subject, in each case, to applicable limitations under the Internal Revenue Code. If we fail to qualify as a REIT for U.S. federal income tax purposes and are able to avail ourselves of one or more of the relief provisions under the Internal Revenue Code in order to maintain our REIT status, we may nevertheless be required to pay penalty taxes of $50,000 or more for each such failure. As a result of all these factors, our failure to qualify as a REIT also could impair our ability to expand our business and raise capital, and could adversely affect the value of our securities.
Qualification as a REIT involves the application of highly technical and complex Internal Revenue Code provisions for which there are only limited judicial and administrative interpretations. The complexity of these provisions and of the applicable Treasury regulations that have been promulgated under the Internal Revenue Code is greater in the case of a REIT that, like us, holds its assets through a partnership. The determination of various factual matters and circumstances not entirely within our control may affect our ability to qualify as a REIT. In order to qualify as a REIT, we must satisfy a number of requirements, including requirements regarding the composition of our assets, the sources of our gross income and the owners of our stock. Our ability to satisfy the asset tests depends upon our analysis of the fair market value of our assets, some of which are not susceptible to precise determination, and for which we will not obtain independent appraisals. Our ability to satisfy the income tests depends on the sources and amounts of our gross income, which we may not be able to control. Also, we must make distributions to stockholders aggregating annually at least 90% of our REIT taxable income, determined without regard to the dividends paid deduction and excluding net capital gains, and we will be subject to U.S. federal corporate income tax to the extent we distribute less than 100% of our REIT taxable income, without regard to the dividends paid deduction and including net capital gains.
We own and may acquire direct or indirect interests in entities that have elected or will elect to be taxed as REITs under the Internal Revenue Code (each, a “Subsidiary REIT”). A Subsidiary REIT is subject to the various REIT qualification requirements and other limitations described herein that are applicable to us. If a Subsidiary REIT were to fail to qualify as a REIT, then (i) that Subsidiary REIT would become subject to U.S. federal income tax, (ii) shares in such Subsidiary REIT would cease to be qualifying assets for purposes of the asset tests applicable to REITs, and (iii) it is possible that we would fail certain of the asset tests applicable to REITs, in which event we would fail to qualify as a REIT unless we could avail ourselves of certain relief provisions.
In addition, legislation, new regulations, administrative interpretations or court decisions may adversely affect our investors, our ability to qualify as a REIT for U.S. federal income tax purposes or the desirability of an investment in a REIT relative to other investments. Although we believe that we have been organized and have operated in a manner that is intended to allow us to qualify for taxation as a REIT, we can give no assurance that we have qualified or will continue to qualify as a
16



REIT for U.S. federal income tax purposes. We have not requested and do not plan to request a ruling from the IRS regarding our qualification as a REIT.
We will pay some taxes, reducing cash available for stockholders.
Even though we qualify as a REIT for U.S. federal income tax purposes, we will be required to pay some U.S. federal, state and local taxes on our income and property. Extra Space Management, Inc. manages stores for our joint ventures and stores owned by third parties. We, jointly with certain corporate subsidiaries, including Extra Space Management, Inc., elected to treat each such subsidiary as a taxable REIT subsidiary (“TRS”) of our Company for U.S. federal income tax purposes. A TRS is subject to U.S. federal corporate income tax, and may also be subject to state and local taxes, on its taxable income. ESM Reinsurance Limited, a wholly-owned subsidiary of Extra Space Management, Inc., generates income from insurance premiums that are subject to U.S. federal income tax and state insurance premiums tax, and pays certain insurance royalties to us. In addition, we will be subject to a 100% penalty tax on certain amounts if the economic arrangements among our tenants, our TRS and us are not comparable to similar arrangements among unrelated parties. Also, if we sell property as a dealer (i.e., to customers in the ordinary course of our trade or business), we will be subject to a 100% penalty tax on any gain arising from such sales. While we do not intend to sell stores as a dealer, the IRS could take a contrary position. To the extent that we are, or any of our TRSs is, required to pay U.S. federal, state or local taxes, we will have less cash available for distribution to stockholders.
Item 1B.     Unresolved Staff Comments
None.
Item 2.     Properties
As of December 31, 2021, we owned or had ownership interests in 1,268 operating stores. Of these stores, 981 are wholly-owned, four are in a consolidated joint venture, and 283 are in unconsolidated joint ventures. In addition, we managed 828 stores for third parties bringing the total number of stores which we own and/or manage to 2,096. These stores are located in 41 states, and Washington, D.C. The majority of our stores are clustered around large population centers. The clustering of assets around these population centers enables us to reduce our operating costs through economies of scale. Our acquisitions have given us an increased scale in many core markets as well as a foothold in many markets where we had no previous presence.
exr-20211231_g1.jpg
As of December 31, 2021, approximately 1,250,000 tenants were leasing storage units at the operating stores that we own and/or manage, primarily on a month-to-month basis, providing the flexibility to increase rental rates over time as market conditions permit. Existing tenants generally receive rate increases at least annually, for which no direct correlation has been drawn to our vacancy trends. Although leases are short-term in duration, the typical tenant tends to remain at our stores for an extended period of time. For stores that were stabilized as of December 31, 2021, the average length of stay was approximately 14.7 months.
The average annual rent per square foot for our existing customers at stabilized stores, net of discounts and bad debt, was $18.03 for the year ended December 31, 2021, compared to $16.21 for the year ended December 31, 2020. Average annual rent per square foot for new leases was $19.53 for the year ended December 31, 2021, compared to $14.64 for the year ended December 31, 2020. The average discounts, as a percentage of rental revenues, during these periods were 3.2% and 3.2%, respectively.
Our store portfolio is made up of different types of construction and building configurations. Most often sites are what we consider “hybrid” facilities, a mix of both drive-up buildings and multi-floor buildings. We have a number of multi-floor buildings with elevator access only, and a number of facilities featuring ground-floor access only.
The following table presents additional information regarding net rentable square feet and the number of stores by state:

Item 3.     Legal Proceedings
We are involved in various legal proceedings and are subject to various claims and complaints arising in the ordinary course of business. Because litigation is inherently unpredictable, the outcome of these matters cannot presently be determined with any degree of certainty. In accordance with applicable accounting guidance, management establishes an accrued liability for litigation when those matters present loss contingencies that are both probable and reasonably estimable. In such cases, there may be an exposure to loss in excess of any amounts accrued. The estimated loss, if any, is based upon currently available information and is subject to significant judgment, a variety of assumptions, and known and unknown uncertainties. We could in the future incur judgments or enter into settlements of claims that could have a material adverse effect on our results of operations in any particular period, notwithstanding the fact that we are currently vigorously defending any legal proceedings against us. For more information on our legal accruals, refer to the Commitments and Contingencies footnote in the notes to the consolidated financial statements in Item 8 of this Form 10-K.
Item 4.     Mine Safety Disclosures
Not applicable.
PART II
Item 5.     Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities
Market Information
Our common stock is traded under the symbol “EXR” on the New York Stock Exchange ("NYSE") since our IPO on August 17, 2004. On February 22, 2022, the closing price of our common stock as reported by the NYSE was $185.28. At February 22, 2022, we had 423 holders of record of our common stock. Certain shares of the Company are held in “street” name and accordingly, the number of beneficial owners of such shares is not known or included in the foregoing number.
Holders of shares of common stock are entitled to receive distributions when declared by our board of directors out of any assets legally available for that purpose. As a REIT, we are required to distribute at least 90% of our “REIT taxable income,” which is generally equivalent to our net taxable ordinary income, determined without regard to the deduction for dividends paid to our stockholders, annually in order to maintain our REIT qualification for U.S. federal income tax purposes. We have historically made regular quarterly distributions to our stockholders.
Information about our equity compensation plans is incorporated by reference in Item 12 of Part III of this Annual Report on Form 10-K.
Issuer Purchases of Equity Securities

In October 2020, our board of directors authorized a three-year share repurchase program allowing the repurchase of shares with an aggregate value up to $400.0 million. As of December 31, 2021, we had remaining authorization to repurchase shares with an aggregate value of $400.0 million.
Unregistered Sales of Equity Securities

All unregistered sales of equity securities during the year ended December 31, 2021 have previously been disclosed in filings with the SEC. On January 6, 2022, we issued a total of 186,766 shares of common stock in connection with the acquisition of two stores. The shares of common stock were valued at a total of $41.0 million. The shares of common stock were issued in a private placement in reliance on Section 4(a)(2) of the Securities Act of 1933, as amended, and the rules and regulations promulgated thereunder. We agreed to register for resale the shares issued in connection with such acquisition on or before April 6, 2022.

Item 7.     Management’s Discussion and Analysis of Financial Condition and Results of Operations
The following discussion should be read in conjunction with the financial statements and notes thereto appearing elsewhere in this report. We make statements in this section that are forward-looking statements within the meaning of the federal securities laws. For a complete discussion of forward-looking statements, see the section in this Form 10-K entitled “Statements Regarding Forward-Looking Information.” Certain risk factors may cause actual results, performance or achievements to differ materially from those expressed or implied by the following discussion. For a discussion of such risk factors, see the section in this Form 10-K entitled “Risk Factors.” Dollar amounts in thousands, except share and per share data, unless otherwise stated.
OVERVIEW
We are a fully integrated, self-administered and self-managed real estate investment trust (“REIT”), formed to own, operate, manage, acquire, develop and redevelop self-storage properties (“stores”). We derive substantially all of our revenues from our two segments: storage operations and tenant reinsurance. Primary sources of revenue for our storage operations segment include rents received from tenants under leases at each of our wholly-owned stores. Our operating results depend materially on our ability to lease available self-storage units, to actively manage unit rental rates, and on the ability of our tenants to make required rental payments. Consequently, management spends a significant portion of their time maximizing cash flows from our diverse portfolio of stores. Revenue from our tenant reinsurance segment consists of insurance revenues from the reinsurance of risks relating to the loss of goods stored by tenants in our stores.
Our stores are generally situated in highly visible locations clustered around large population centers. The clustering of our assets around these population centers enables us to reduce our operating costs through economies of scale. To maximize the performance of our stores, we employ industry-leading revenue management systems. Developed by our management team, these systems enable us to analyze, set and adjust rental rates in real time across our portfolio in order to respond to changing market conditions. We believe our systems and processes allow us to more pro-actively manage revenues.
We operate in competitive markets, often where consumers have multiple stores from which to choose. Competition has impacted, and will continue to impact, our store results. We experience seasonal fluctuations in occupancy levels, with occupancy levels generally higher in the summer months due to increased moving activity. We believe that we are able to respond quickly and effectively to changes in local, regional and national economic conditions by adjusting rental rates through the combination of our revenue management team and our industry-leading technology systems. We consider a store to be in the lease-up stage after it has been issued a certificate of occupancy, but before it has achieved stabilization. We consider a store to be stabilized once it has achieved either an 80% occupancy rate for a full year measured as of January 1 of the current year, or has been open for three years prior to January 1 of the current year.
CRITICAL ACCOUNTING POLICIES AND ESTIMATES
Our financial statements have been prepared in accordance with U.S. generally accepted accounting principles. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amount of assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. On an ongoing basis, we evaluate our estimates and assumptions, including those that impact our most critical accounting policies. We base our estimates and assumptions on historical experience and on various other factors that we believe are reasonable under the circumstances. A summary of significant accounting policies is also provided in the notes to our consolidated financial statements (see Note 2 to our consolidated financial statements). Actual results may differ from these estimates. We believe the following are our most critical accounting policies and estimates:
CONSOLIDATION: Arrangements that are not controlled through voting or similar rights are accounted for as variable interest entities (“VIEs”). An enterprise is required to consolidate a VIE if it is the primary beneficiary of the VIE.

Under certain circumstances when we enter into arrangements for the formation of joint ventures, a VIE may be created.  The primary factors that require the most judgment in determining whether the joint venture is a VIE are whether the decisions that most significantly impact the entity’s economic performance were controlled by the equity holders as a group, and whether the joint venture has sufficient equity to finance its activities without additional subordinated support.
If the joint venture is determined to be a VIE, we perform a qualitative analysis, including considering which party, if any, has the power to direct the activities most significant to the economic performance of each VIE and whether that party has the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could be significant to the VIE. If we are determined to be the primary beneficiary of the VIE, the assets, liabilities and operations of the VIE are consolidated within
19



our financial statements. Otherwise, our investment is generally accounted for under the equity method. Our ability to correctly assess the influence or control over an entity affects the presentation of the investment in our consolidated financial statements.
As of December 31, 2021 we had one consolidated VIE consisting of four stores. As of December 31, 2020 we had no consolidated VIEs.
REAL ESTATE ASSETS: We account for the acquisition of stores, including by merger and other acquisitions of real estate, in accordance with ASC 805-10, "Business Combinations." We use our judgment to determine if assets acquired meet the definition of a business or if the acquisition should be considered an asset acquisition. We must make significant assumptions and estimates in determining the fair value of the tangible and intangible assets and liabilities acquired and consideration transferred. These fair value estimates are sensitive to: price of land per square foot and current replacement cost estimates, including adjustments for the age, class, height, square footage, condition, location, and turnkey factor. These assumptions and estimates require judgment, and therefore others could come to materially different conclusions as to the estimated fair values, which could result in differences in depreciation and amortization expense, gains and losses on the sale of real estate assets, and real estate and intangible asset values.
EVALUATION OF ASSET IMPAIRMENT: Long lived assets held for use are evaluated for impairment when events or circumstances indicate that there may be impairment. We review each store at least annually to determine if any such events or circumstances have occurred or exist. We focus on stores where occupancy and/or rental income have decreased by a significant amount. For these stores, we determine whether the decrease is temporary or permanent and whether the store will likely recover the lost occupancy and/or revenue in the short term. In addition, we review stores in the lease-up stage and compare actual operating results to original projections. We may not have identified all material facts and circumstances that affect impairment of our stores. No material impairments were recorded in the year ended December 31, 2021.
DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES: We hold a number of derivative instruments which we use to hedge our exposure to variability in expected future cash flows, mainly related to our interest rates on variable interest debt. We do not use derivatives for trading or speculative purposes. We assess our derivatives both at inception, and on an ongoing quarterly basis, for whether the derivatives used in hedging transactions are effective. The rules and interpretations relating to the accounting for derivatives are complex. Failure to apply this guidance correctly may require us to recognize all changes in fair value of the hedged derivative in earnings, which may materially impact our results.
INCOME TAXES: We have elected to be treated as a REIT under Sections 856 through 860 of the Internal Revenue Code. In order to maintain our qualification as a REIT, among other things, we are required to distribute at least 90% of our REIT taxable income to our stockholders and meet certain tests regarding the nature of our income and assets. As a REIT, we are not subject to U.S. federal income tax with respect to that portion of our income which meets certain criteria and is distributed annually to our stockholders. We plan to continue to operate so that we meet the requirements for taxation as a REIT. Many of these requirements, however, are highly technical and complex. For any taxable year that we fail to qualify as a REIT and for which applicable statutory relief provisions did not apply, we would be subject to U.S. federal corporate income tax on all of our taxable income for at least that year and the ensuing four years. We could also be subject to penalties and interest, and our net income may be materially different from the amounts reported in our financial statements.
We have elected to treat certain corporate subsidiaries, including Extra Space Management, Inc., as a TRS. In general, a TRS may perform additional services for tenants and generally may engage in any real estate or non-real estate related business. A TRS is subject to U.S. federal corporate income tax and may also be subject to state and local income taxes. Interest and penalties relating to uncertain tax positions will be recognized in income tax expense when incurred. If tax authorities determine that amounts paid by any of our TRSs to us are not reasonable compared to similar arrangements among unrelated parties, we could be subject to a penalty tax on the excess payments.
RECENT ACCOUNTING PRONOUNCEMENTS: For a discussion of recent accounting pronouncements affecting our business, see Item 8, “Financial Statements and Supplementary Data–Recently Issued Accounting Standards.”

RESULTS OF OPERATIONS
Comparison of the Year Ended December 31, 2021 to the Year Ended December 31, 2020
Overview
Results for the year ended December 31, 2021 included the operations of 1,268 stores (981 wholly-owned, four in consolidated joint ventures, and 283 in joint ventures accounted for using the equity method) compared to the results for the year ended December 31, 2020, which included the operations of 1,197 stores (944 wholly-owned, six in a consolidated joint venture, and 247 in joint ventures accounted for using the equity method). Material or unusual changes in the results of our operations are discussed below.

exr-20211231_g2.jpg

Revenues
The following table presents information on revenues earned for the years indicated:
 For the Year Ended December 31,
 20212020$ Change% Change
Property rental$1,340,990 $1,157,522 $183,468 15.9 %
Tenant reinsurance170,108 146,561 23,547 16.1 %
Management fees and other income66,264 52,129 14,135 27.1 %
Total revenues$1,577,362 $1,356,212 $221,150 16.3 %

Property Rental—The increase in property rental revenues for the year ended December 31, 2021 was primarily the result of an increase of $151,217 at our stabilized stores related to high occupancy and increased rents to new and existing customers. Property rental revenue also increased by $40,792 associated with acquisitions completed in 2021 and 2020. We acquired 74 stores during the year ended December 31, 2021 and we acquired 23 stores during the year ended December 31, 2020. Property rental revenue also increased by $5,193 during the year ended December 31, 2021 as a result of increases in occupancy at our lease-up stores. These increases were offset by approximately $15,460 related to the sale of 16 stores into a new joint venture and 16 stores to a third party during 2021.
Tenant Reinsurance—The increase in tenant reinsurance revenues was due primarily to an increase in the number of stores operated and the higher average occupancy across the portfolio. We operated 2,096 stores at December 31, 2021, compared to 1,921 stores at December 31, 2020.
Management Fees and Other Income—Management fees and other income represent the fees collected for our management of stores owned by third parties and unconsolidated joint ventures and other transaction fee income. The increase for the year ended December 31, 2021 was primarily due to an increase in the number of stores managed. As of December 31, 2021, we managed 1,115 stores for third parties and joint ventures compared to 977 stores as of December 31, 2020.

Expenses
The following table presents information on expenses for the years indicated:
 For the Year Ended December 31,
 20212020$ Change% Change
Property operations$368,608 $360,615 $7,993 2.2 %
Tenant reinsurance 29,488 26,494 2,994 11.3 %
General and administrative102,194 96,594 5,600 5.8 %
Depreciation and amortization241,879 224,444 17,435 7.8 %
Total expenses$742,169 $708,147 $34,022 4.8 %
Property Operations—The increase in property operations expense consists primarily of an increase of $13,440 related to acquisitions completed in 2021 and 2020. We acquired 74 stores during the year ended December 31, 2021 and acquired 23 stores during the year ended December 31, 2020. The increase was partially offset by a decrease in expense of $(4,755) related to property sales.
Tenant Reinsurance—Tenant reinsurance expense represents the costs that are incurred to provide tenant reinsurance. The increase in tenant reinsurance expense for the year ended December 31, 2021 was due primarily to the increase in total number of stores operated compared to the prior year and major storm events that occurred causing an increase in claim payouts. We operated 2,096 stores at December 31, 2021, compared to 1,921 stores at December 31, 2020.
General and Administrative—General and administrative expenses primarily include all expenses not directly related to our stores, including corporate payroll, travel and professional fees. These expenses are recognized as incurred. During 2021, we experienced higher than average turnover and extended times to fill. Additionally, we experienced wage pressure which led to increases in wages of approximately 10% nationwide. These trends will directly increase general & administrative expenses in 2022. No other material trends in specific travel or other expenses were observed.
Depreciation and Amortization—Depreciation and amortization expense increased as a result of the acquisition of new stores. We acquired 74 stores during the year ended December 31, 2021, and acquired 23 stores during the year ended December 31, 2020.
Other Income and Expenses
The following table presents information on other revenues and expenses for the years indicated:
 For the Year Ended December 31,
 20212020$ Change% Change
Gain on real estate transactions$140,760 $18,075 $122,685 678.8 %

Total other expense, net$42,565 $(130,483)$173,048 (132.6)%

Gain on Real Estate Transactions — During the first quarter of 2021, we sold 16 stores to a newly established unconsolidated joint venture for a total sales price of $168,885 resulting in a gain of $63,477. Additionally, we sold 16 stores during the fourth quarter of 2021 to a third party for a total sales price of $204,500 resulting in a gain of $73,854.
22



Interest Expense—The decrease in interest expense during the year ended December 31, 2021 was primarily the result of a lower average interest rate when compared to the same period in the prior year. Information on the total face value of debt and the average interest rate for each quarter during the years ended December 31, 2021 and December 31, 2020 is set forth in the following table:
 For the Three Months Ended December 31,For the Three Months Ended September 30,For the Three Months Ended June 30,For the Three Months Ended March 31,

Average interest rate2.6%2.7%2.8%3.0%2.8%3.0%2.7%3.1%
Non-cash Interest Expense Related to Amortization of Discount on Equity Component of Exchangeable Senior Notes—Represents the amortization of the discounts related to the equity components of the exchangeable senior notes issued by our Operating Partnership. The exchangeable senior notes had an effective interest rate of 4.0% relative to the carrying amount of the liability. The notes were paid in full in November 2020.
Interest Income—Interest income represents amounts earned on cash and cash equivalents deposited with financial institutions, interest earned on bridge loans and debt securities and income earned on notes receivable from common and preferred Operating Partnership unit holders. In late 2018 we began to provide bridge financing on completed properties owned by third parties that we manage. The total principal balance of bridge loans receivable as of December 31, 2021 was $279,042, compared to $187,368 as of December 31, 2020. We also purchased a senior mezzanine note receivable with a principal amount of $103,000 in July 2020. The increase in interest income during the year ended December 31, 2021 was primarily the result of interest earned on these loans as well as interest earned from our investment in preferred stock of Jernigan Capital, Inc. ("JCAP"), in connection with the acquisition of JCAP by affiliates of NexPoint Advisors, L.P., which was purchased in November 2020 for $300,000.
Equity in Earnings and Dividend Income from Unconsolidated Real Estate Entities—Equity in earnings of unconsolidated real estate ventures represents the income earned through our ownership interests in unconsolidated real estate ventures. In joint ventures, we and our joint venture partners generally receive a preferred return on our invested capital. To the extent that cash or profits in excess of these preferred returns are generated, we receive a higher percentage of the excess cash or profits, as applicable. Dividend income represents dividends from our investment in convertible preferred stock of SmartStop, which was purchased in October 2019 for $150,000 with another $50,000 invested in October 2020. The increase in earnings for the year ended December 31, 2021 is related in part to the dividend income from the secondary investment of SmartStop preferred stock. Additionally the increases related to the higher income at our joint ventures are due to store performance and the acquisition of 45 stores with new and existing joint venture partners. These increases were offset by the sale of our equity interest in 22 stores.
Equity in Earnings of Unconsolidated Real Estate Ventures—Gain on Sale of Real Estate Assets and Purchase of Joint Venture Partner's Interest—In June 2021, we sold our interest in two unconsolidated single store joint ventures to our joint ventures partner. We received proceeds of $1,888 in cash and recorded a gain of $525. Also, as of June 2021, the WICNN JV LLC and GFN JV LLC joint ventures sold all 17 of the stores owned by the joint ventures to a third party. Subsequent to the sales, these joint ventures were dissolved. As a result of these transactions, we recorded a gain of $5,739.
Income Tax Expense—For the year ended December 31, 2021, the increase in income tax expense was the result of an increase in income earned by our TRS when compared to the same period in the prior year.
Comparison of the Year Ended December 31, 2020 to the Year Ended December 31, 2019

The results of operations for the years ended December 31, 2020 compared to December 31, 2019 was included in our Annual Report on Form 10-K for the year ended December 31, 2020 on page 19, under Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” which was filed with the SEC on February 26, 2021.
FUNDS FROM OPERATIONS
Funds from operations ("FFO") provides relevant and meaningful information about our operating performance that is necessary, along with net income and cash flows, for an understanding of our operating results. We believe FFO is a meaningful disclosure as a supplement to net earnings. Net earnings assume that the values of real estate assets diminish
23



predictably over time as reflected through depreciation and amortization expenses. The values of real estate assets fluctuate due to market conditions and we believe FFO more accurately reflects the value of our real estate assets. FFO is defined by the National Association of Real Estate Investment Trusts, Inc. (“NAREIT”) as net income computed in accordance with U.S. generally accepted accounting principles (“GAAP”), excluding gains or losses on sales of operating stores and impairment write-downs of depreciable real estate assets, plus real estate related depreciation and amortization and after adjustments to record unconsolidated partnerships and joint ventures on the same basis. We believe that to further understand our performance, FFO should be considered along with the reported net income and cash flows in accordance with GAAP, as presented in the consolidated financial statements. FFO should not be considered a replacement of net income computed in accordance with GAAP.
The computation of FFO may not be comparable to FFO reported by other REITs or real estate companies that do not define the term in accordance with the current NAREIT definition or that interpret the current NAREIT definition differently. FFO does not represent cash generated from operating activities determined in accordance with GAAP, and should not be considered as an alternative to net income as an indication of our performance, as an alternative to net cash flow from operating activities as a measure of our liquidity, or as an indicator of our ability to make cash distributions.
The following table presents the calculation of FFO for the periods indicated:

SAME-STORE RESULTS
Comparison of the Year Ended December 31, 2021 to the Year Ended December 31, 2020
Our same-store pool for the periods presented consists of 842 stores that are wholly-owned and operated and that were stabilized by the first day of the earliest calendar year presented. We consider a store to be stabilized once it has been open for three years or has sustained average square foot occupancy of 80% or more for one calendar year. We believe that by providing same-store results from a stabilized pool of stores, with accompanying operating metrics including, but not limited to: occupancy, rental revenue growth, operating expense growth, net operating income growth, etc., stockholders and potential investors are able to evaluate operating performance without the effects of non-stabilized occupancy levels, rent levels, expense levels, acquisitions or completed developments.  Same-store results should not be used as a basis for future same-store performance or for the performance of our stores as a whole. The following table presents operating data for our same-store portfolio:

Same-store rental revenues$1,199,750 $1,054,669 13.8%

Same-store revenues for the year ended December 31, 2021 increased compared to the prior year, due to higher average occupancy, higher average rates to new and existing customers and higher late fees partially offset by higher discounts. Expenses were lower for the year ended December 31, 2021 compared to the prior year, primarily due to decreases in payroll and marketing expense, partially offset by increases in property taxes, credit card processing fees, repairs and maintenance expense and insurance expense.

CASH FLOWS

Cash flows from operating activities increased as expected due to our continued growth in revenues and through the increase in the number of properties we own and operate. Cash flows used in investing activities relate primarily to our acquisitions and development of new stores, sales of stores, investments in unconsolidated real estate entities and notes receivable from bridge loans, and fluctuate depending on our actions in those areas. Cash flows from financing activities depend primarily on our debt and equity financing activities. A summary of cash flows along with significant components are as follows:
For the Year Ended December 31,

We believe that cash flows generated by operations, along with our existing cash and cash equivalents, the availability of funds under our existing lines of credit, and our access to capital markets will be sufficient to meet all of our reasonably anticipated cash needs during the next twelve months. These cash needs include operating expenses, monthly debt service payments, recurring capital expenditures, acquisitions, funding for new notes receivable for bridge loans, building redevelopments and expansions, distributions to unit holders and dividends to stockholders necessary to maintain our REIT qualification.

We expect to generate positive cash flow from operations and we consider projected cash flows in our sources and uses of cash. These cash flows are principally derived from rents paid by our tenants. A significant deterioration in projected cash flows from operations could cause us to increase our reliance on available funds under our existing lines of credit, curtail planned capital expenditures, or seek other additional sources of financing.

LIQUIDITY AND CAPITAL RESOURCES
Financing Strategy
We will continue to employ leverage in our capital structure in amounts reviewed from time to time by our board of directors. Although our board of directors has not adopted a policy which limits the total amount of indebtedness that we may incur, we will consider a number of factors in evaluating our level of indebtedness from time to time, as well as the amount of such indebtedness that will be either fixed or variable rate. In making financing decisions, we will consider factors including but not limited to:
 
the interest rate of the proposed financing;
the extent to which the financing impacts flexibility in managing our stores;
prepayment penalties and restrictions on refinancing;
the purchase price of stores acquired with debt financing;
long-term objectives with respect to the financing;
target investment returns;
the ability of particular stores, and our company as a whole, to generate cash flow sufficient to cover expected debt service payments;
overall level of consolidated indebtedness;
timing of debt maturities;
provisions that require recourse and cross-collateralization; and
corporate credit ratios including fixed charge coverage ratio and max secured/unsecured indebtedness.
Our indebtedness may be recourse, non-recourse, cross-collateralized, cross-defaulted, secured or unsecured. In addition, we may invest in stores subject to existing loans collateralized by mortgages or similar liens, or may refinance stores acquired on a leveraged basis. We may use the proceeds from any borrowings to refinance existing indebtedness, to refinance investments, including the redevelopment of existing stores, for general working capital or to purchase additional interests in partnerships or joint ventures or for other purposes when we believe it is advisable.
As of December 31, 2021, we had $71,126 available in cash and cash equivalents. Our cash and cash equivalents are held in accounts managed by third party financial institutions and consist of invested cash and cash in our operating accounts. During 2021 and 2020, we experienced no loss or lack of access to our cash or cash equivalents; however, there can be no assurance that access to our cash and cash equivalents will not be impacted by adverse conditions in the financial markets.
As of December 31, 2021, we had $5,984,113 face value of debt, resulting in a debt to total enterprise value ratio of 15.6%. As of December 31, 2020, we had $5,767,771 face value of debt, resulting in a debt to total enterprise value ratio of 27.5%. As of December 31, 2021, the ratio of total fixed-rate debt and other instruments to total debt was 75.3% (including $1,983,145 on which we have interest rate swaps that have been included as fixed-rate debt). As of December 31, 2020, the ratio of total fixed-rate debt and other instruments to total debt was 63.1% (including $2,091,269 on which we have interest rate swaps that have been included as fixed-rate debt). The weighted average interest rate of total debt at December 31, 2021 and 2020 was 2.6% and 2.7%, respectively.
In January 2021, we received a Baa2 rating from Moody's Investors Service and in July 2019, we obtained a BBB/Stable rating from S&P. We intend to manage our balance sheet to preserve such ratings. Certain of our real estate assets are pledged as collateral for our debt. We have a total of 752 unencumbered stores as defined by our public bonds. Our unencumbered asset value is calculated as $13,498,591 and our total asset value is calculated as $18,072,262 according to the calculations as defined by our public bonds. We are subject to certain restrictive covenants relating to our outstanding debt. We were in compliance with all financial covenants at December 31, 2021.
We expect to fund our short-term liquidity requirements, including operating expenses, recurring capital expenditures, dividends to stockholders, distributions to holders of Operating Partnership units and interest on our outstanding indebtedness, out of our operating cash flow, cash on hand and borrowings under our revolving lines of credit. In addition, we are pursuing additional sources of financing based on anticipated funding needs.
Our liquidity needs consist primarily of operating expenses, monthly debt service payments, recurring capital expenditures, distributions to unit holders and dividends to stockholders necessary to maintain our REIT qualification. We may from time to time seek to repurchase our outstanding debt, shares of common stock or other securities in open market purchases, privately negotiated transactions or otherwise. Such repurchases, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. In addition, we evaluate, on an ongoing basis, the merits of strategic acquisitions and other relationships, which may require us to raise additional funds. We may also use

Operating Partnership units as currency to fund acquisitions from self-storage owners who desire tax-deferral in their exiting transactions.
CONTRACTUAL OBLIGATIONS
As of December 31, 2021, the weighted average interest rate for all fixed rate debt was 3.1%, and the weighted average interest rate on all variable rate debt was 1.3%.
For more information on our contractual obligations related to real estate acquisitions, refer to our commitments and contingencies footnote in the notes to the consolidated financial statements in Item 8 of this Form 10-K.
SEASONALITY
The self-storage business has been subject to seasonal fluctuations. A greater portion of revenues and profits is typically realized from May through September. Historically, our highest level of occupancy has been at the end of July, while our lowest level of occupancy has been in late February and early March. Results for any quarter may not be indicative of the results that may be achieved for the full fiscal year.
Item 7A.     Quantitative and Qualitative Disclosures About Market Risk
Market Risk
Market risk refers to the risk of loss from adverse changes in market prices and interest rates. Our future income, cash flows and fair values of financial instruments are dependent upon prevailing market interest rates.
Interest Rate Risk
Interest rate risk is highly sensitive to many factors, including governmental monetary and tax policies, domestic and international economic and political considerations and other factors beyond our control.
As of December 31, 2021, we had approximately $5,984,113 in total face value debt, of which approximately $1,477,679 was subject to variable interest rates (excluding debt with interest rate swaps). If LIBOR were to increase or decrease by 100 basis points, the increase or decrease in interest expense on the variable rate debt would increase or decrease future earnings and cash flows by approximately $14,777 annually.
Interest rate risk amounts were determined by considering the impact of hypothetical interest rates on our financial instruments. These analyses do not consider the effect of any change in overall economic activity that could occur. Further, in the event of a change of that magnitude, we may take actions to further mitigate our exposure to the change. However, due to the uncertainty of the specific actions that would be taken and their possible effects, these analyses assume no changes in our financial structure.
Derivative Instruments
We use derivative instruments to help manage interest rate risk using designated hedge relationships. Interest rate swaps involve the exchange of fixed-rate and variable-rate interest payments between two parties based on a contractual underlying notional amount, but do not involve the exchange of the underlying notional amounts. See our Derivatives footnote in our Notes to consolidated financial statements in Item 8 for additional information about our use of derivative contracts.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of Extra Space Storage Inc.
Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of Extra Space Storage Inc. (the Company) as of December 31, 2021 and 2020, 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, 2021, and the related notes and financial statement schedule listed in the Index at Item 8 (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021, in conformity with U.S. generally accepted accounting principles.
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, 2021, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated February 28, 2022 expressed an unqualified opinion thereon.
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 regarding 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 Matter
The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the account or disclosure to which it relates.
Purchase price allocation
Description of the Matter
For the year ended December 31, 2021, the Company completed the acquisition of 70 self-storage properties (“stores”) for a total purchase price of $1.1 billion. As further discussed in Note 2 of the consolidated financial statements, the transactions were accounted for as asset acquisitions, and the purchase price was allocated to the real estate assets acquired based on their relative fair values, which are estimated using unobservable inputs.
Auditing the accounting for the Company’s 2021 acquisitions of stores was subjective because in determining the fair value of acquired land and buildings, the Company had to rely on unobservable inputs due to the lack of available directly comparable market information. In particular, the fair value estimates were sensitive to assumptions such as price of land per square foot, and current replacement cost estimates, including adjustments for the age, class, height, square footage, condition, location, and turnkey factor associated with the acquired assets.
How We Addressed the Matter in Our AuditWe obtained an understanding, evaluated the design, and tested the operating effectiveness of controls over management’s accounting for acquired stores, including controls over the review of assumptions underlying the purchase price allocation and accuracy of the underlying data used. For example, we tested controls over the determination of the fair value of the land and building assets, including the controls over the review of the valuation models and the underlying assumptions used to develop such estimates.
For the 2021 store acquisitions described above, our procedures included, but were not limited to, evaluating the Company’s valuation methodologies and evaluating the significant assumptions used to determine the fair value of the assets acquired. For certain of these asset acquisitions, we tested the completeness and accuracy of the underlying data by, among other things, recalculating the current replacement cost of buildings and comparing the adjustments for the age, class, height, square footage, condition, location, and turnkey factor with the acquired assets to industry publications. Additionally, we also compared significant assumptions, including prices per square foot to third-party sources such as recent land sales. For certain of these asset acquisitions, we involved our valuation specialists to assist in the assessment of the methodology utilized by the Company, in addition to performing corroborative analyses to assess whether the conclusions in the valuation were supported by observable market data. For example, our valuation specialists used independently identified data sources to evaluate management’s selected comparable land sales and replacement cost assumptions.
