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, 20172020 we owned and/or operated 1,4831,921 stores in 3940 states, Washington, D.C. and Puerto Rico, comprising approximately 112149.2 million square feet of net rentable space in approximately 1,020,0001.4 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 the Company’sour stores. We previously reported our financial statements in three segments, but based on operational changes and the way our management reviews company performance, we realigned our financial statements into two reportable segments. 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. Federalfederal tax, with certain exceptions, on our netREIT 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 Public Reference Room at 100 F Street, N.E., Washington, D.C. 20549, by calling the SEC at 1-800-SEC-0330 or by accessing 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, 1316 years; Scott Stubbs, Executive Vice President and Chief Financial Officer, 1720 years; Samrat Sondhi, Executive Vice President and Chief OperatingMarketing Officer, 1418 years; Gwyn McNeal, Executive Vice President and Chief Legal Officer, 1215 years; James Overturf,Matt Herrington, Executive Vice President and Chief MarketingOperations Officer, 1913 years; Noah Springer, Executive Vice President and Kenneth M. Woolley,Chief Strategy and Partnership Officer, 15 years; Zach Dickens, Executive Chairman, 39Vice President and Chief Investment Officer, 18 years.
Our executive management team and board of directors have an ownership position in the Company with executive officers and directors owning approximately 4,059,6692,887,647 shares or 3.2%2.2% of our outstanding common stock as of February 21, 2018.19, 2021.
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 sitestore managers and staff are also contributing factors to a site’sstore’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 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.
Since inception in the early 1970’s, the self-storage industry has experienced significant growth. The self-storage industry is a mature industry that has also seen increases inthe average occupancy over the past several years.continue to increase. According to the Self-Storage Almanac (the “Almanac”), in 2012,2014, the national average physical occupancy rate was 85.0%89.1% of net rentable square feet, compared to an average physical occupancy rate of 92.8%92.2% in 2017.2020. Our average occupancy for wholly-owned stores for 2020 was 93.1%.
The industry is also characterized by fragmented ownership. According to the Almanac, as of the end of 2017,2020, the top ten self-storage companies in the United States operated approximately 15.8%21.4% of the total U.S. stores, and the top 50 self-storage companies operated approximately 19.2%27.4% of the total U.S. stores. We believe this fragmentation will contribute to continued consolidation at some level in the future.
RecentlyWe 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 believe that we are well positioned to compete for acquisitions.
We are the second largest self-storage operator in the United States. We are one of five public self-storage REITs along with CubeSmart, Life Storage, National Storage Affiliates Life Storage 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 storageself-storage stores
Our acquisitions team continues to pursue the acquisition of multi-store portfolios and single stores 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 stabilized stores, from time to time we also 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 in 20182021 as we continue to acquire Certificate of Occupancy stores.
ExpandGrow 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 implemented a bridge lending program, under which we provide financing to operating properties that we manage.  We anticipate that this program will help us increase our management business, create additional future acquisition opportunities, and strengthen our relationships with partners, all while providing interest and fee income. We generally originate mortgage loans and mezzanine loans, with the intent to sell the mortgage loans to third parties, while retaining our interests in the mezzanine loans.
Invest in other self-storage businesses selectively
We have recently made investments in preferred stock of other self-storage companies. These investments benefit us by not only providing dividend income, but also have increased our management business, creating additional future acquisition opportunities through creating and strengthening 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 properties.stores.
Credit Lines - We have twothree 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, 2017,2020, our Credit Lines had available capacity of $600.0 million,$1.2 billion, of which $506.0$241.0 million was undrawn.
Secured and Unsecured Debt - Historically, we havehad primarily used traditional secured mortgage loans to finance store acquisitions and development efforts. More recently, we obtainedobtain unsecured bank term loans and issuedissue unsecured private placement bonds. We will continue to utilize a combination of secured and unsecured financing for future store acquisitions and development. As of December 31, 2017,2020, we had $2.8$2.2 billion of secured notes payable and $1.7$2.6 billion of unsecured notes payable outstanding compared to $2.9$2.2 billion of secured notes payable and $1.0$2.7 billion of unsecured notes payable and senior exchangeable notes outstanding as of December 31, 2016.2019.
Equity - We have an active "at the market" (ATM)("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, 2016,2020, we issued 1,381,300899,048 shares of common stock through our ATM program and received net proceeds of approximately $123.4$103.5 million. No shares were issued under the ATM program duringDuring the year ended December 31, 2017.2019, we issued 1,779,200 shares of common stock through our ATM program and received net proceeds of approximately $198.8 million.
We view equity interests in our Operating Partnership as a potentialanother source of capital that can also provide an attractive tax planning opportunitiesopportunity 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 Venture FinancingVentures - As of December 31, 2017,2020, we owned 215253 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 generally 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.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 yearsyear ended December 31, 2017 and 2016,2020, we sold 36four stores into a joint venture and nine stores to an outside party, respectively,located in Florida for approximately $295.0 million and $30.3$46.6 million. For the year ended December 31, 2019, we sold one store located in New York for $11.3 million. For the year ended December 31, 2018, we sold one store located in California for $40.2 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. Our stores are also subject to various state of emergency regulations enacted as a result of the COVID-19 pandemic and expect such regulations to remain in effect throughout 2021.
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. 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.
EmployeesHuman Capital
As of December 31, 2017,2020, we had 3,3804,013 employees and believe our relationship with our employees is good. Our employees are not represented by a collective bargaining agreement. In 2020, we invited our employees to participate in an employee satisfaction survey. We achieved an overall satisfaction score of over 90%.
The Company offers competitive health benefits and encourages its employees to participate in employee health and wellness programs. Over 70% 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.
In order to attract and retain top talent, we offer training and development opportunities for our employees. In 2020, we invested in training and development for our employees, which included leadership training, communication training, individual learning plans, site manager training and mentorship programs. Our field employees received on average 8.2 hours of training in 2020. 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 the pandemic, we chose to close our doors to in-person customers until we could install personal protective equipment for our employees. We understood that such a dramatic move would affect our revenues, but felt that as a company it was more important to ensure the safety of our employees. We moved quickly to put the necessary equipment in place and reopened with a safer and more sanitized environment for our employees.
7



The Company undertakes a wide spectrum of initiatives to attract and retain a diverse workforce. The Company has a Diversity and Inclusion Committee that has been active since 2018. During 2020, the Company launched implicit bias and allyship training for its employees, produced videos featuring our CEO discussing the importance of diversity and inclusion to the Company. 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.
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.


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
8



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


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 rely on information technology in our operations, 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
9



processing, transmission and storage of confidential tenant and other sensitive information. 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. 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. 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.
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. For example, a current California law commonly referred to as Proposition 13 generally limits annual real estate tax increases on California properties to 2% of assessed value. However, under Proposition 13, property tax reassessment generally occurs as a result of a "change in ownership" of a property, as specially defined for purposes of those rules. Because the property taxing authorities may not determine whether there has been a "change in ownership" or the actual reassessed value of a property for a period of time after a transaction has occurred, we may not know the impact of a potential reassessment for a considerable amount of time following a particular transaction. 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. In addition from time to time voters and lawmakers have announced initiatives to repeal or amend Proposition 13 to eliminate its application to commercial and industrial property and/or introduce split tax roll legislation. Such initiatives, if successful, could increase the assessed value and/or tax rates applicable to commercial property in California, including our stores.
The COVID-19 pandemic or other pandemics could adversely affect our results of operations.
During 2020, the United States and other countries around the world have been experiencing 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. Federal, state and local jurisdictions have issued varying forms of states of emergency orders. We are working to comply within the framework of local, county, state and federal laws as they evolve. In that regard, we have implemented a wide range of practices to protect and support our employees and customers. Such measures include instituting “work from home” measures at our corporate offices and call center, instituting a contactless rental process that allows our on-site employees to continue to rent storage units without physical interaction, and providing personal protective equipment to on-site employees providing essential functions so that hygiene and “social distancing” standards can be effectively managed and applied. We have transitioned many of our interactions between customers and leasing and support staff to on-line and telephonic communications. Due to the COVID-19 pandemic, our customers may be impacted, including through unemployment, which may impact their ability to pay rent or renew their leases.
Our business has been impacted by COVID-19 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. These impacts from COVID-19 were especially prevalent during the second quarter of 2020. As restrictions began to lessen during the second half of 2020, we saw some 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 in the latter half of 2020.
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, 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, 2017,2020, we held interests in 215253 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
11



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, 2017,2020, we had approximately $4.6$5.8 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 netREIT 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 netREIT taxable income each year.year, determined without regard to the deduction for dividends paid and including net capital gains.
12



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, 2017,2020, we had approximately $4.6$5.8 billion of debt outstanding, of which approximately $1.2$2.1 billion, or 25.3%36.9% was subject to variable interest rates (excluding debt with interest rate swaps). This variable rate debt had a weighted average interest rate of approximately 3.1%1.6% 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.
Uncertainty relating to the LIBOR calculation process and potential phasing out of LIBOR may affect our financial results.
In July 2017, the Financial Conduct Authority (the authority that regulates LIBOR) announced it intended to stop compelling banks to submit rates for the calculation of LIBOR after June 30, 2021. The Alternative Reference Rates Committee (“ARRC”) has proposed that the Secured Overnight Financing Rate (“SOFR”) is the rate that represents best practice as the alternative to LIBOR for use in derivatives and other financial contracts that are currently indexed to LIBOR. ARRC has proposed a paced market transition plan to SOFR from LIBOR and organizations are currently working on industry wide and company specific transition plans as it relates to derivatives and cash markets exposed to LIBOR. In November 2020, the Federal Reserve Board along with various independent groups announced the potential for certain USD LIBOR tenors to continue to be published until June 2023. This change would allow most legacy USD LIBOR contracts to mature before disruptions occur in the USD LIBOR market, without the need to transition those contracts to SOFR. We are not able to predict when LIBOR may be limited or discontinued or when there will be sufficient liquidity in the SOFR market.
We have outstanding debt and hedge contracts indexed to LIBOR. Due to the extension noted above, we currently expect that all of our then-outstanding contracts indexed to LIBOR will be required to be transitioned to an alternative rate by June 30, 2023. However, it is possible that LIBOR may be discontinued or our contracts may be transitioned to an alternative rate (which may or may not be a SOFR-based rate) prior to then. We are monitoring industry transition plans and evaluating the risks related to our debt and hedge contracts indexed to LIBOR. If a published U.S. dollar LIBOR rate is unavailable after 2021, the interest rates on these instruments which are indexed to LIBOR will be determined using alternative methods, which may result in interest obligations which are more than or do not otherwise correlate over time with the payments that would have been made on such debt if U.S. dollar LIBOR was available in its current form. Further, the same costs and risks that may lead to the unavailability of U.S. dollar LIBOR may make one or more of the alternative methods impossible or impracticable to
13



determine. Any of these proposals or consequences could have a material adverse effect on our financing costs, and as a result, our financial condition, operating results and cash flows.
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 the 2017 Tax Legislation (defined below),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 after December 31, 2017 and 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.
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 IRSInternal 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.

Recently enacted U.S. tax legislation (the “2017 Tax Legislation”) has significantly changed the U.S. federal income taxation of U.S. businesses and their owners, including REITs and their stockholders. Changes made by the 2017 Tax Legislation that could affect us and our stockholders include:

permanently eliminating the progressive corporate tax rate structure, which previously imposed a maximum corporate tax rate of 35%, and replacing it with a corporate tax rate of 21%;
permitting a deduction for certain pass-through business income, including dividends received by our stockholders from us that are not designated by us as capital gain dividends or qualified dividend income, which will allow individuals, trusts and estates to deduct up to 20% of such amounts for taxable years beginning after December 31, 2017 and before January 1, 2026;
reducing the highest rate of withholding with respect to our distributions to non-U.S. stockholders that are treated as attributable to gains from the sale or exchange of U.S. real property interests from 35% to 21%;
limiting our deduction for net operating losses arising in taxable years beginning after December 31, 2017 to 80% of REIT taxable income (determined without regard to the dividends paid deduction);
generally limiting the deduction for net business interest expense in excess of 30% of a business’s “adjusted taxable income,” except for taxpayers that engage in certain real estate businesses (including most equity REITs) and elect out of this rule (provided that such electing taxpayers must use an alternative depreciation system with longer depreciation periods); and
eliminating the corporate alternative minimum tax.



Many of these changes are effective immediately, without any transition periods or grandfathering for existing transactions. The legislation is unclear in many respects and could be subject to potential amendments and technical corrections, as well as interpretations and implementing regulations by the Treasury and IRS, any of which could lessen or increase the impact of the legislation. In addition, it is unclear how these U.S. federal income tax changes will affect state and local taxation, which often uses federal taxable income as a starting point for computing state and local tax liabilities. While some of the changes made by the tax legislation may adversely affect us in one or more reporting periods and prospectively, other changes may be beneficial on a going forward basis. We are continuing to work with our tax advisors to determine the full impact that the recent federal tax reform legislation, which we refer to herein as the 2017 Tax Legislations, as a whole will have on us.
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. Federalfederal 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
14



make distributions to stockholders aggregating annually at least 90% of our netREIT 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 netREIT 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 REIT for U.S. federal income tax purposes. We have not requested and do not plan to request a ruling from the Internal Revenue ServiceIRS 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 Extra Space Management, Inc.each such subsidiary as a taxable REIT subsidiary (“TRS”) of our Company for U.S. federal income tax purposes. A TRS is a fully taxable corporation,subject to U.S. federal corporate income tax, and may also be limited insubject to state and local taxes, on its ability to deduct interest payments made to us.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 TRSTRSs 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, 2017,2020, we owned or had ownership interests in 1,0611,197 operating stores. Of these stores, 846944 are wholly-owned, one issix are in a consolidated joint venture,ventures, and 214247 are in unconsolidated joint ventures. In addition, we managed an additional 422724 stores for third parties bringing the total number of stores which we own and/or manage to 1,483.1,921. These stores are located in 3940 states, Washington, D.C. and Puerto Rico. 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-20201231_g1.jpg

As of December 31, 2017,2020, approximately 835,0001,135,000 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, 2017,2020, the average length of stay was approximately 14.615.4 months.
The average annual rent per square foot for our existing customers at stabilized stores, net of discounts and bad debt, was $15.98$16.33 for the year ended December 31, 2017,2020, compared to $15.30$16.39 for the year ended December 31, 2016.2019. Average annual rent per square foot for new leases was $16.77$14.81 for the year ended December 31, 2017,2020, compared to $15.96$14.88 for the year ended December 31, 2016.2019. The average discounts, as a percentage of rental revenues, during these periods were 3.9%3.1% and 3.6%, 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.

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.

(1)The adoption of FASB ASU 2017-01 on January 1, 2017, has resulted in a decrease in acquisition related costs as the Company’s acquisition of operating stores are considered asset acquisitions rather than business combinations.
(2)
In connection with our adoption of Financial Accounting Standards Board (“FASB”) ASU 2015-3, "Simplifying the Presentation of Debt Issuance Costs," in fiscal year 2016, debt issuance costs, with the exception of those related to our revolving credit facility, have been reclassified from other assets to a reduction of the carrying amount of the related debt liability. Prior year amounts have been reclassified to conform to the current period’s presentation.
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.” AmountsDollar amounts in thousands, except share and per share data.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 the Company'sour stores. Our segment presentation has changed from the prior year, and all applicable information has been reclassified to conform to the current year's segment presentation.
Our stores are generally situated in highly visible locations clustered around large population centers. These areas enjoy above average population growth and income levels. 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.
We have concluded that under
Under certain circumstances when we enter into arrangements for the formation of joint ventures, a VIE may be created.  For eachThe primary factors that require the most judgment in determining whether the joint venture is a VIE created,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 have performedperform 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 with within
17



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, 2017,2020 and 2019, we had no consolidated VIEs. Additionally, our Operating Partnership has notes payable to three trusts that are considered VIEs. Since the Operating Partnership is not the primary beneficiary of the trusts, these VIEs are not consolidated.
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 subsequent to our January 1, 2017 adoption of ASU 2017-01, "Business Combinations (Topic 805) - Clarifying the Definition of a Business."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 purchase and 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, 2017.2020.
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. Any ineffective portion of a derivative financial instrument's change in fair value is immediately recognized in earnings. 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 one of ourcertain corporate subsidiaries, including Extra Space Management, Inc., as a taxable REIT subsidiary (“TRS”).TRS. In general, oura 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.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 taxable REIT subsidiariesTRSs to us are not reasonable compared to similar arrangements among unrelated parties, we could be subject to a penalty tax on the excess payments.

During 2014, we acquired a portfolio of five stores where we agreed to make an additional cash payment to the sellers if the acquired stores exceeded a specified amount of net operating income for the years ending December 31, 2015 and 2016. As the operating income of these stores during the earnout period was higher than originally estimated, an additional payment was due to the sellers of $4,284, which was recorded as a loss during 2016.

In 2011, we acquired a single store in Florida. As part of the acquisition, we agreed to make an additional cash payment to the sellers if the acquired store exceeded a specified amount of net rental income for the period of 12 consecutive months ending June 30, 2015. During 2014, we recorded a liability of $2,500 as an estimate of the payment that would become due. The $400 gain recorded during 2015 represents the adjustment needed to true up the existing liability to the amount owed to the sellers as of June 30, 2015.

During 2015, we determined that one of our acquisitions was purchased at below its market value, and therefore recorded a $1,101 gain at the time of the acquisition, which represents the excess of the fair value of the store acquired over the consideration paid.
Interest Expense—The increase in interest expense during the year ended December 31, 2016 was primarily the result of higher debt balances when compared to the prior year. The total face value of our debt, including our lines of credit, was $4,363,697 at December 31, 2016 compared to $3,598,254 at December 31, 2015.
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.
Interest Income—Interest income represents amounts earned on cash and cash equivalents deposited with financial institutions and interest earned on notes receivable.
Interest Income on Note Receivable from Preferred Operating Partnership Unit Holder—Represents interest on a $100,000 loan to the holder of the Operating Partnership’s Series A Participating Redeemable Preferred Units (the “Series A Units”).


Equity in Earnings of Unconsolidated Real Estate Ventures—Equity in earnings of unconsolidated real estate ventures represents the income earned through our ownership interests in unconsolidated joint ventures.
Equity in Earnings of Unconsolidated Real Estate Ventures—Gain on Sale of Real Estate Assets and Purchase of Joint Venture Partners’ Interests— In 2016 we had several large transactions with our joint venture partners. We acquired 11 stores from our WCOT joint venture in a step acquisition. We recorded a gain of $4,651 as a result of the transaction. Similarly, we acquired 23 stores from our PRISA II joint venture in a separate step acquisition and recorded a gain of $6,778 on the transaction. Immediately after the step acquisition, we sold our interest in the PRISA II joint venture 2020, which still owned 42 properties, to our joint venture partners, and recognized a gain of $30,846. Lastly, we acquired six stores from our VRS joint venture in a step acquisition, where we again recorded a gain of $26,923.
During March 2015, one of our joint ventures sold a store located in New York to a third party and we recorded a gain of $1,228 on the transaction. Additionally, in March 2015 we acquired a joint venture partner’s 82.4% equity interest in an existing joint venture. We recognized a non-cash gain of $1,629 during the three months ended March 31, 2015 as a result of re-measuring the fair value of our 17.6% equity interest in this joint venture held before the acquisition.
Income Tax Expense—The increase in income tax expense relates primarily towas the result of an increase in income earned by our TRS when compared to the same periodsperiod in the prior year.
Comparison of the Year Ended December 31, 2019 to the Year Ended December 31, 2018

The results of operations for the years ended December 31, 2019 compared to December 31, 2018 was included in our Annual Report on Form 10-K for the year ended December 31, 2019 on page 18, 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 25, 2020.
FUNDS FROM OPERATIONS
FFOFunds 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 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
21



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.

SAME-STORE RESULTS
Comparison of the Year Ended December 31, 20172020 to the Year Ended December 31, 20162019
Our same-store pool for the periods presented consists of 701859 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.

Same-store revenues for the three months and year ended December 31, 2017 increased due to gains in occupancy and higher rental rates for both new and existing customers. Expenses were higher for the three months ended December 31, 2017, primarily due to increases in property taxes, payroll and benefits and marketing, which were partially offset by decreases in repairs and maintenance and insurance. Expenses for the year ended December 31, 20172020 were moderatelyessentially flat, due to higher average occupancy, partially offset by lower rental rates to existing customers, lower late fees and higher bad debt expense related to non-paying tenants.

Cash provided byflows from operating activities was $597,375 and $539,263 for the years ended December 31, 2017 and 2016, respectively. The change when compared to the prior year was primarilyincreased as expected due to a $117,133 increaseour continued growth in net income, a decrease in gain on sale of real estate assetsrevenues and purchase joint venture partners' interests of $69,199 and an increase in depreciation and amortization expense of $10,736.

We believe that cash flows generated by operations, along with our existing cash and cash equivalents, the year ended December 31, 2017, compared to cash provided by financing activitiesavailability of $460,831 for the year ended December 31, 2016. The change related primarily to a decrease in proceeds from notes payable and revolvingfunds under our existing lines of credit, and our access to capital markets will be sufficient to meet all of $574,734our 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 a decreaseexpansions, distributions to unit holders and dividends to stockholders necessary to maintain our REIT qualification.

We expect to generate positive cash flow from operations in net proceeds2020, and we consider these projected cash flows in our sources and uses of cash. These cash flows are principally derived from the sale of common stock of $123,424 for the year ended December 31, 2017 when comparedrents paid by our tenants. A significant deterioration in projected cash flows from operations could cause us to the prior year. These decreases were partially offset by a decrease in principal paymentsincrease our reliance on notes payable and revolvingavailable funds under our existing lines of credit, curtail planned capital expenditures, or seek other additional sources of $33,763.financing.
Comparison of the Year Ended December 31, 2016 to the Year Ended December 31, 2015
Cash provided by operating activities was $539,263 and $367,329 for the years ended December 31, 2016 and 2015, respectively. The change when compared to the prior year was primarily due to a $187,553 increase in net income and an increase in depreciation and amortization expense of $49,103. These increases were offset by an increase in the gain on sale of real estate assets and purchase joint venture partners’ interests of $66,342. This gain was primarily the result of three step acquisitions of stores that were previously owned by our VRS, PRISA II and WCOT joint ventures, along with the gain on the sale of our remaining interest in the PRISA II joint venture to Prudential.
Cash used in investing activities was $1,032,035 and $1,625,664, for the years ended December 31, 2016 and 2015, respectively. The decrease was primarily due to a decrease in total cash paid for the acquisition of real estate assets of $464,227. We purchased 99 stores during the year ended December 31, 2016, compared to 171 stores purchased during 2015. There was also an increase in proceeds from sale of real estate assets, investments in real estate ventures and other assets of $60,013, a decrease in cash paid on the purchase/issuance of notes receivable of $57,902 and an increase in cash received from principal payments on notes receivable of $42,785 for the year ended December 31, 2016 when compared to 2015.

Cash provided by financing activities was $460,831 and $1,286,471, for the years ended December 31, 2016 and 2015, respectively. The change related primarily to a decrease in proceeds from notes payable and revolving lines of credit of $221,445, a decrease in net proceeds from the issuance of exchangeable senior notes of $563,500, and a decrease in net proceeds from the sale of common stock of $323,453 for the year ended December 31, 2016 when compared to the prior year. These decreases were partially offset by a decrease in principal payments on notes payable and revolving lines of credit of $191,128 and a decrease in the cash paid for the repurchase of exchangeable senior notes of $205,017.

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 Companycompany 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, 2017,2020, we had $55,683$109,124 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 20172020 and 2016,2019, 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, 2017,2020, we had $4,601,322$5,767,771 face value of debt, resulting in a debt to total enterprise value ratio of 28.1%27.5%. As of December 31, 2016,2019, we had $4,363,697$5,076,501 face value of debt, resulting in a debt total enterprise value ratio of 29.6%25.9%. As of December 31, 2017,2020, the ratio of total fixed-rate debt and other instruments to total debt was 74.7%63.1% (including $2,283,049$2,091,269 on which we have interest rate swaps that have been included as fixed-rate debt). As of December 31, 2016,2019, the ratio of total fixed-rate debt and other instruments to total debt was 70.0%78.7% (including $2,198,275$2,290,356 on which we have interest rate swaps that have been included as fixed-rate debt). The weighted average interest rate of the total of fixed- and variable-rate debt at December 31, 20172020 and 20162019 was 3.3%2.7% and 3.0%3.3%, respectively.
In July 2019, we obtained a BBB/Stable rating from S&P and in January 2021 we received a Baa2 rating from Moody's Investors Service. 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 are subject to certain restrictive covenants relating to our outstanding debt. We were in compliance with all financial covenants at December 31, 2017.2020.
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 cashoperating expenses, monthly debt service payments, recurring capital expenditures, distributions to unit holders and dividends to stockholders store acquisitions, principal payments undernecessary to maintain our borrowings and non-recurring capital expenditures.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.

OFF-BALANCE SHEET ARRANGEMENTS


Except as disclosed in the notes to our financial statements, we do not currently have any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purposes entities, which typically are established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. Further, except as disclosed in the notes to our financial statements, we have not guaranteed any obligations of unconsolidated entities nor do we have any commitments or intent to provide funding to any such entities. Accordingly, we are not materially exposed to any financing, liquidity, market or credit risk that could arise if we had engaged in these relationships.

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 is subject to seasonal fluctuations. A greater portion of revenues and profits are 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.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, 2017,2020, we had approximately $4.6 billion$5,767,771 in total face value debt, of which approximately $1.2 billion$2,130,551 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 $11.6 million$21,306 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.

In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 20172020 and 2016,2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2017,2020, 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’sCompany's internal control over financial reporting as of December 31, 2017,2020, 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 March 1, 2018February 26, 2021 expressed an unqualified opinion thereon.

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.

Purchase price allocation
Description of the MatterFor the year ended December 31, 2020, the Company completed the acquisition of 23 self-storage properties (“stores”) for a total purchase price of $296.7 million. 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 2020 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 2020 store acquisitions described above, our procedures included evaluating the Company’s valuation methodologies and testing the significant assumptions used to determine the fair value of the assets acquired. 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. 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.

1.     DESCRIPTION OF BUSINESS
Extra Space Storage Inc. (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 professionally managed self-storage properties located throughout the United States. The Company was formed to continue the business of Extra Space Storage LLC and its subsidiaries, which had engaged in the self-storage business since 1977. The Company’s interest in its stores is held through its operating partnership, Extra Space Storage LP (the “Operating Partnership”), which was formed on May 5, 2004. The Company’s 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.
The Company invests in stores by acquiring wholly-owned stores or by acquiring an equity interest in real estate entities. At December 31, 2017,2020, the Company had direct and indirect equity interests in 1,0611,197 storage facilities. In addition, the Company managed 422724 stores for third parties bringing the total number of stores which it owns and/or manages to 1,483.1,921. These stores are located in 3940 states, Washington, D.C. and Puerto Rico. The Company also offers tenant reinsurance at its owned and managed stores that insures the value of goods in the storage units.
2.     SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Basis of Presentation
The consolidated financial statements are presented on the accrual basis of accounting in accordance with U.S. generally accepted accounting principles (“GAAP”) and include the accounts of the Company and its wholly- or majority-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.
In our Segment Information in Note 18, the number of segments has changed from three to two. The prior years' segment information has been reclassified to conform to the current year's presentation.
Variable Interest Entities
The Company accounts for arrangements that are not controlled through voting or similar rights as variable interest entities (“VIEs”). An enterprise is required to consolidate a VIE if it is the primary beneficiary of the VIE. A VIE is created when (i) the equity investment at risk is not sufficient to permit the entity to finance its activities without additional subordinated financial support from other parties, or (ii) the entity’s equity holders as a group either: (a) lack the power, through voting or similar rights, to direct the activities of the entity that most significantly impact the entity’s economic performance, (b) are not obligated to absorb expected losses of the entity if they occur, or (c) do not have the right to receive expected residual returns of the entity if they occur. If an entity is deemed to be a VIE, the enterprise that is deemed to have a variable interest, or combination of variable interests, that provides the enterprise with a controlling financial interest in the VIE, is considered the primary beneficiary and must consolidate the VIE.
The Company has concluded that under certain circumstances when the Company enters into arrangements for the formation of joint ventures or when entering into a new bridge loan agreement, a VIE may be created under condition (i), (ii) (b) or (c) of the previous paragraph. For each VIE created, the Company has performed 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 the Company is determined to be the primary beneficiary of the VIE, the assets, liabilities and operations of the VIE are consolidated with the Company’s financial statements. Additionally,As of December 31, 2020 and 2019, the Operating Partnership has notes payable to three trusts that are VIEs under condition (ii)(a) above. Since the Operating Partnership is not the primary beneficiary of the trusts, these VIEs are not consolidated.Company had no consolidated VIEs.
The Company’s investments in real estate joint ventures, where the Company has significant influence, but not control, and joint ventures which are VIEs in which the Company is not the primary beneficiary, are recorded under the equity method of accounting on the accompanying consolidated financial statements.

Use of Estimates
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Fair Value Disclosures
Derivative financial instruments
Currently, the Company uses interest rate swaps to manage its interest rate risk. The valuation of these instruments is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves. The fair values of interest rate swaps are determined using the market standard methodology of netting the discounted future fixed cash payments and the discounted expected variable cash receipts. The variable cash receipts are based on an expectation of future interest rates (forward curves) derived from observable market interest rate forward curves.
The Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees. In conjunction with the Financial Accounting Standard Board’s fair value measurement guidance, the Company made an accounting policy election to measure the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counterparty portfolio.
Although the Company has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by itself and its counterparties. However, as of December 31, 2017,2020, the Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuation of its derivatives. As a result, the Company has determined that its derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy.


The table below presents the Company’s assets and liabilities measured at fair value on a recurring basis as of December 31, 2017,2020, aggregated by the level in the fair value hierarchy within which those measurements fall.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis
Long-lived assets held for use are evaluated for impairment when events or circumstances indicate there may be impairment. The Company reviews each store at least annually to determine if any such events or circumstances have occurred or exist. The Company focuses on stores where occupancy and/or rental income have decreased by a significant amount. For these stores, the Company determines 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, the Company reviews stores in the lease-up stage and compares actual operating results to original projections.
EXTRA SPACE STORAGE INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)
Amounts in thousands, except store and share data, unless otherwise stated


When the Company determines that an event that may indicate impairment has occurred, the Company compares the carrying value of the related long-lived assets to the undiscounted future net operating cash flows attributable to the assets. An impairment loss is recorded if the net carrying value of the assets exceeds the undiscounted future net operating cash flows attributable to the assets. The impairment loss recognized equals the excess of net carrying value over the related fair value of the assets.
When real estate assets are identified by management as held for sale, the Company discontinues depreciating the assets and estimates the fair value of the assets, net of selling costs. The Company compares the carrying value of the related long-lived assets to the undiscounted future net operating cash flows attributable to the assets (categorized within Level 3 of the fair value hierarchy). If the estimated fair value, net of selling costs, of the assets that have been identified as held for sale is less than the net carrying value of the assets, the Company would recognize a loss on the assets held for sale. The operations of assets held for sale or sold during the period are presented as part of normal operations for all periods presented.
The Company assesses annually whether there are any indicators that the value of the Company’s investments in unconsolidated real estate venturesentities may be impaired and when events or circumstances indicate that there may be impairment. An investment is impaired if management’s estimate of the fair value of the investment is less than its carrying value. To the extent impairment has occurred, and is considered to be other than temporary, the loss is measured as the excess of the carrying amount of the investment over the fair value of the investment.
As of December 31, 20172020 and 2016,2019, the Company did not have any assets or liabilities measured at fair value on a nonrecurring basis.


Fair Value of Financial Instruments
The carrying values of cash and cash equivalents, restricted cash, receivables, other financial instruments included in other assets, accounts payable and accrued expenses, variable-rate notes payable, investments in debt securities and notes receivable, revolving lines of credit and other liabilities reflected in the consolidated balance sheets at December 31, 20172020 and 2016,2019, approximate fair value.
The fair values of the Company’s notes receivable and notes receivable from Preferred Operating Partnership unit holders and other fixed rate notes receivable were based on the discounted estimated future cash flow of the notes (categorized within Level 3 of the fair value hierarchy); the discount rate used approximated the current market rate for loans with similar maturities and credit quality. The fair values of the Company’s fixed rate notes payable and notes payable to trusts were estimated using the discounted estimated future cash payments to be made on such debt (categorized within Level 3 of the fair value hierarchy); the discount rates used approximated current market rates for loans, or groups of loans, with similar maturities and credit quality. The fair value of the Company’s exchangeable senior notes was estimated using an average market price for similar securities obtained from a third party.

Real Estate Assets
Real estate assets are stated at cost, less accumulated depreciation. Direct and allowable internal costs associated with the development, construction, renovation, and improvement of real estate assets are capitalized. Interest, property taxes, and other costs associated with development incurred during the construction period are capitalized. The construction period begins when expenditures for the real estate assets have been made and activities that are necessary to prepare the asset for its intended use are in progress. The construction period ends when the asset is substantially complete and ready for its intended use.

Expenditures for maintenance and repairs are charged to expense as incurred. Major replacements and betterments that improve or extend the life of the asset are capitalized and depreciated over their estimated useful lives. Depreciation is computed using the straight-line method over the estimated useful lives of the buildings and improvements, which are generally between five and 39 years.
Stores purchased at the timeThe purchase of certificate of occupancy issuance and stores purchased subsequent to the Company's adoption of ASU 2017-01 on January 1, 2017 are considered asset acquisitions. As such, the purchase price is allocated to the real estate assets acquired based on their relative fair values, which are estimated using significant unobservable inputs. The value of the tangible assets, consisting of land and buildings, is determined as if vacant. Intangible assets, which represent the value of existing tenant relationships, are recorded at their relative fair values based on the avoided cost to replace the current leases. The Company measures the value of tenant relationships based on the rent lost due to the amount of time required to replace existing customers, which is based on the Company’s historical experience with turnover in its stores. Any debt assumed as part of the acquisition is recorded at fair value based on current interest rates compared to contractual rates. Acquisition-related transactions costs are capitalized as part of the purchase price.


Intangible lease rights represent: (1) purchase price amounts allocated to leases on three3 stores that cannot be classified as ground or building leases; these rights are amortized to expense over the life of the leases and (2) intangibles related to ground leases on eight8 stores where the leases were assumed by the Company at rates that were lower than the current market rates for similar leases. The values associated with these assumed leases were recorded as intangibles, which will be amortized over the lease terms.
Real Estate Sales
In general, sales of real estate and related profits/losses are recognized when all consideration has changed hands and risks and rewards of ownership have been transferred. Certain types of continuing involvement preclude sale treatment and related profit recognition; other forms of continuing involvement allow for sale recognition but require deferral of profit recognition.
Investments in Unconsolidated Real Estate VenturesEntities
Investments in unconsolidated real estate entities and cash distributions in unconsolidated real estate ventures represent the Company's noncontrolling interest in real estate joint ventures that own stores and the Company's interest in preferred stock of SmartStop Self Storage REIT, Inc. ("SmartStop"). The Company’s investments in real estate joint ventures, where the Company has significant influence, but not control and joint ventures which are VIEs in which the Company is not the primary beneficiary, are recorded under the equity method of accounting in the accompanying consolidated financial statements.
Under the equity method, the Company’s investment in real estate ventures is stated at cost and adjusted for the Company’s share of net earnings or losses and reduced by distributions. Equity in earnings of real estate ventures is generally recognized based on the Company’s ownership interest in the earnings of each of the unconsolidated real estate ventures. For the purposes of presentation in the statement of cash flows, the Company follows the “look through”“nature of distribution” approach for classification of distributions from joint ventures. Under this approach, distributionscash flows are reported underclassified on the basis of the nature of the activity or activities of the investee that generated the distribution as either a return on investment (classified as a cash inflow from operating cash flow unless the facts and circumstances of a specific distribution clearly indicate that it isactivities) or a return of capital (e.g.,investment (classified as a liquidating dividend or distributioncash inflow from investing activities).
The Company evaluated its investments in preferred stock of non-public real estate entities and determined it did not have significant influence over the entity, and the investment in preferred stock does not have a readily determinable fair value, therefore it has been recorded at the transaction price. The Company periodically evaluates the investment for impairment. No impairment indicators were noted as of December 31, 2020.

Investments in Debt Securities and Notes Receivable
The Company accounts for its investment in debt securities and loans receivable at amortized cost. The Company recognizes interest income related to the debt securities and notes receivable using the effective interest method, with deferred fees and costs amortized over the lives of the proceeds fromrelated loans as yield adjustment. Additionally, the joint venture’s salediscount related to purchased notes receivable is being amortized to interest income over the remaining period of assets), in which case it is reported as an investing activity.the notes.
Cash and Cash Equivalents
The Company’s cash is deposited with financial institutions located throughout the United States and at times may exceed federally insured limits. The Company considers all highly liquid debt instruments with a maturity date of three months or less to be cash equivalents.
Restricted Cash
Restricted cash is comprised of letters of credit and escrowed funds deposited with financial institutions located throughout the United States relating to earnest money deposits on potential acquisitions, real estate taxes, loan collateral, operating reserves and insurance and capital expenditures.

Other Assets
Other assets consist of equipment and fixtures, capitalized software, rents receivable from our tenants, investments in trusts, notes and other receivables, other intangible assets, deferred tax assets, prepaid expenses and the fair value of interest rate swaps. Depreciation of equipment and fixtures is computed on a straight-line basis over three to five years. The Company capitalizes certain costs during the application development stage when developing software for internal use. As of December 31, 2020 and 2019, unamortized software costs were $22,708 and $22,354, respectively. During the year ended December 31, 2020, the Company recorded amortization expense of $1,571 relating to capitalized software costs. No significant amortization of software costs was recorded prior to 2020 as the software was still in the application development stage.
Derivative Instruments and Hedging Activities
The Company records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. The Company may enter into derivative contracts that are intended to economically hedge certain of its risk, even though hedge accounting does not apply or the Company elects not to apply hedge accounting. The Company made an accounting policy election to measure the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counterparty portfolio.
Risk Management and Use of Financial Instruments
In the normal course of its ongoing business operations, the Company encounters economic risk. There are three3 main components of economic risk: interest rate risk, credit risk and market risk. The Company is subject to interest rate risk on its interest-bearing liabilities. Credit risk is the risk of inability or unwillingness of tenants to make contractually required payments. Market risk is the risk of declines in the value of stores due to changes in rental rates, interest rates or other market factors affecting the value of stores held by the Company. The Company has entered into interest rate swap agreements to manage a portion of its interest rate risk.

Exchange of Common Operating Partnership Units
Redemption of common Operating Partnership units for shares of common stock, when redeemed under the original provisions of the Operating Partnership agreement, are accounted for by reclassifying the underlying net book value of the units from noncontrolling interest to the Company’s equity.
Revenue and Expense Recognition
Rental revenues are recognized as earned based upon amounts that are currently due from tenants. Leases are generally on month-to-month terms. Prepaid rents are recognized on a straight-line basis over the term of the leases. Promotional discounts are recognized as a reduction to rental income over the promotional period. Late charges, administrative fees and merchandise sales and truck rentals are recognized as income when earned. Management fee revenues are recognized monthly as services are performed and in accordance with the terms of the related management agreements. Equity in earnings of unconsolidated real estate entitiesventures is recognized based on the Company's ownership interest in the earnings of each of the unconsolidated real estate entities. Interest income is recognized as earned.
The Company's management fees are earned subject to the terms of the related management services agreements ("MSAs"). These MSAs provide that the Company will perform management services, which include leasing and operating the property and providing accounting, marketing, banking, maintenance and other services. These services are provided in exchange for monthly management fees, which are based on a percentage of revenues collected from stores owned by third parties and unconsolidated joint ventures. MSAs generally have original terms from three to five years, after which management services are provided on a month-to-month basis unless terminated. Management fees are due on the last day of each calendar month that management services are provided.
The Company accounts for the management services provided to a customer as a single performance obligation which are rendered over time each month. The total amount of consideration from the contract is variable as it is based on monthly revenues, which are influenced by multiple factors, some of which are outside the Company's control. Therefore, the Company recognizes the revenue at the end of each month once the uncertainty is resolved. Due to the standardized terms of the MSAs, the Company accounts for all MSAs in a similar, consistent manner. Therefore, no disaggregated information relating to MSAs is presented.
Property expenses, including utilities, property taxes, repairs and maintenance and other costs to manage the facilities are recognized as incurred. The Company accrues for property tax expense based upon invoice amounts estimates and historical trends.estimates. If these estimates are incorrect, the timing of expense recognition could be affected.
Tenant reinsurance premiums are recognized as revenue over the period of insurance coverage. The Company records an unpaid claims liability at the end of each period based on existing unpaid claims and historical claims payment history. The unpaid claims liability represents an estimate of the ultimate cost to settle all unpaid claims as of each period end, including both reported but unpaid claims and claims that may have been incurred but have not been reported. The Company uses a third party claims administrator to adjust all tenant reinsurance claims received. The administrator evaluates each claim to determine the ultimate claim loss and includes an estimate for claims that may have been incurred but not reported. Annually, a third party

actuary evaluates the adequacy of the unpaid claims liability. Prior year claim reserves are adjusted as experience develops or new information becomes known. The impact of such adjustments is included in the current period operations. The unpaid claims liability is not discounted to its present value. Each tenant chooses the amount of insurance coverage they want through the tenant reinsurance program. Tenants can purchase policies in amounts of 2,000 dollars to 10,000 dollars of insurance coverage in exchange for a monthly fee. As of December 31, 2017,2020, the average insurance coverage for tenants was approximately 2,8003,100 dollars. The Company’s exposure per claim is limited by the maximum amount of coverage chosen by each tenant. The Company purchases reinsurance for losses exceeding a set amount for any one event. The Company does not currently have any amounts recoverable under the reinsurance arrangements.

Income Taxes
The Company has elected to be treated as a REIT under Sections 856 through 860 of the Internal Revenue Code of 1986, as amended ("the Internal(the "Internal Revenue Code"). In order to maintain its qualification as a REIT, among other things, the Company is required to distribute at least 90% of its REIT taxable income to its stockholders and meet certain tests regarding the nature of its income and assets. As a REIT, the Company is not subject to U.S. federal income tax with respect to that portion of its income which meets certain criteria and is distributed annually to stockholders. The Company plans to continue to operate so that it meets the requirements for taxation as a REIT. Many of these requirements, however, are highly technical and complex. For any taxable year that the Company fails to qualify as a REIT and for which applicable statutory relief provisions did not apply, wethe Company would be taxed at the regularsubject to U.S. federal corporate ratesincome tax on all of ourits taxable income for at least that year and the ensuing four years. The Company is subject to certain state and local taxes. Provision for such taxes has been included in income tax expense on the Company’s consolidated statements of operations. For the year ended December 31, 2017,2020, 0% (unaudited) of all distributions to stockholders qualified as a return of capital.
The Company owns 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 the Company. 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 the Company would fail certain of the asset tests applicable to REITs, in which event the Company would fail to qualify as a REIT unless it could avail itself of certain relief provisions.
The Company has elected to treat itscertain corporate subsidiary,subsidiaries, including Extra Space Management, Inc. (“ESMI”), as a taxable REIT subsidiary (“TRS”). In general, the Company’sa TRS may perform additional services for tenants and may engage in any real estate or non-real estate related business.

Stock-Based Compensation
The measurement and recognition of compensation expense for all share-based payment awards to employees and directors are based on estimated fair values. Awards granted are valued at fair value and any compensation expense is recognized over the service periods of each award.
Earnings Per Common Share
Basic earnings per common share is computed using the two-class method by dividing net income attributable to common stockholders by the weighted average number of common shares outstanding during the period. All outstanding unvested restricted stock awards contain rights to non-forfeitable dividends and participate in undistributed earnings with common stockholders; accordingly, they are considered participating securities that are included in the two-class method. Diluted earnings per common share measures the performance of the Company over the reporting period while giving effect to all potential common shares that were dilutive and outstanding during the period. The denominator includes the weighted average number of basic shares and the number of additional common shares that would have been outstanding if the potential common shares that were dilutive had been issued, and is calculated using either the two-class, treasury stock or as if-converted method, whichever is most dilutive. Potential common shares are securities (such as options, convertible debt, Series A Participating Redeemable Preferred Units (“Series A Units”), Series B Redeemable Preferred Units (“Series B Units”), Series C Convertible Redeemable Preferred Units (“Series C Units”), Series D Redeemable Preferred Units (“Series D Units” and together with the Series A Units, Series B Units and Series C Units, the “Preferred OP Units") and common Operating Partnership units (“OP Units”)) that do not have a current right to participate in earnings of the Company but could do so in the future by virtue of their option, redemption or conversion right.
In computing the dilutive effect of convertible securities, net income is adjusted to add back any changes in earnings in the period associated with the convertible security. The numerator also is adjusted for the effects of any other non-discretionary changes in income or loss that would result from the assumed conversion of those potential common shares. In computing diluted earnings per common share, only potential common shares that are dilutive (those that reduce earnings per common share) are included. For the years ended December 31, 2017, 20162020 and 2015,2019, there were 0 anti-dilutive shares outstanding. For the year ended December 31, 2018, options to purchase approximately 45,286, 88,552, and 62,25436,075 shares of common stock respectively, were excluded from the computation of earnings per share as their effect would have been anti-dilutive.
For the purposes of computing the diluted impact of the potential exchange of the Preferred Operating PartnershipOP Units for common shares upon redemption, where the Company has the option to redeem in cash or shares and where the Company has stated the intent and ability to settle the redemption in shares, Thethe Company divided the total liquidation value of the Preferred Operating Partnership unitsOP Units by the average share price of $78.59$103.62 for the year ended December 31, 2017.2020.

The Operating Partnership had $575,000 of its 3.125% Exchangeable Senior Notes due 2035 (the “2015 Notes”) issued and outstanding as of December 31, 2017.prior to their redemption in November 2020. The 2015 Notes could potentially have had a dilutive impact on the Company’s earnings per share calculations. The 2015 Notes arewere exchangeable by holders into shares of the Company’s common stock under certain circumstances per the terms of the indenture governing the 2015 Notes. The exchange price of the 2015 Notes was $93.80 per share as of December 31, 2017, and could change over time as described in the indenture. The Company hashad irrevocably agreed to pay only cash for the accreted principal amount of the 2015 Notes relative to its exchange obligations, but retained the right to satisfy the exchange obligation in excess of the accreted principal amount in cash and/or common stock.
Though the Company has retained that right, Accounting Standards Codification (“ASC”) 260, “Earnings per Share,” requires an assumption that shares would be used to pay the exchange obligation in excess of the accreted principal amount, and requires that those shares be included in the Company’s calculation of weighted average common shares outstanding for the diluted earnings per share computation. For the yearsyear ended December 31, 2017, 20162020, the Company had repaid the principal and accrued interest of its 2015 344,430Notes, and therefore, 0 shares 309,730 shares and 513,040 shares, respectively, relatedrelating to the 20132015 Notes were included in the computation forof diluted earnings per share.

For the purposes of computing the diluted impact on earnings per share of the potential exchange of Series A Units for common shares upon redemption, where the Company has the option to redeem in cash or shares and where the Company has stated the positive intent and ability to settle at least $101,700 of the instrument in cash (or net settle a portion of the Series A Units against the related outstanding note receivable), only the amount of the instrument in excess of $101,700 is considered in the calculation of shares contingently issuable for the purposes of computing diluted earnings per share as allowed by ASC 260-10-45-46.

Recently Issued Accounting Standards
In May 2014, the FASB issued ASU 2014-9, “Revenue from Contracts with Customers,” which amends the guidance for revenue recognition to replace numerous, industry-specific requirements and converges areas under this topic with those of the International Financial Reporting Standards. ASU 2014-9 outlines a five-step process for customer contract revenue recognition that focuses on transfer of control, as opposed to transfer of risk and rewards. The amendment also requires enhanced disclosures regarding the nature, amount, timing and uncertainty of revenues and cash flows from contracts with customers. ASU 2014-9 includes all contracts with customers to provide goods and services in the ordinary course of business, except for certain contracts that are specifically excluded from the scope, such as lease contracts and insurance contracts. Entities can transition to the standard either retrospectively or as a cumulative-effect adjustment as of the date of adoption. ASU 2014-9 will become effective for annual and interim periods beginning after December 15, 2017 with early adoption on the original effective date permitted. The Company has determined that its property rental revenue and tenant reinsurance revenue will not be subject to the guidance in ASU 2014-9, as they qualify as lease contract and insurance contracts, which are excluded from its scope. The Company's management fee revenue will be included in the scope of ASU 2014-9, however, revenue recognized under ASU 2014-9 will not differ materially from revenue recognized under existing guidance. The Company anticipates adopting the standard using the modified retrospective transition method as of January 1, 2018.
In February 2016, the FASBFinancial Accounting Standards Board ("FASB") issued ASU 2016-02, "Leases (Topic 842)," which modifies the accounting for leases, intending to increase transparency and comparability of organizations by requiring balance sheet presentation of leased assets and increased financial statement disclosure of leasing arrangements. ASU 2016-02 will require

requires entities to recognize a liability for their lease obligations and a corresponding asset representing the right to use the underlying asset over the lease term. Lease obligations are to be measured at the present value and accounted for using the effective interest method. The accounting for the leased asset will differ slightly depending on whether the agreement is deemed to be a financing or operating lease. For finance leases, the leased asset is depreciated on a straight-line basis and recorded separately from the interest expense in the statements of operations, resulting in higher expense in the earlier part of the lease term. For operating leases, the depreciation and interest expense components are combined, recognized evenly over the term of the lease, and presented as a reduction to operating income. ASU 2016-02 requires that assets and liabilities be presented or disclosed separately, and requires additional disclosure of certain qualitative and quantitative information related to these lease agreements. ASU 2016-02 isbecame effective for annual and interim periods beginning after December 15, 2018. The Company is currently assessingadopted the standard using the modified retrospective approach as of January 1, 2019. The Company elected the package of practical expedients upon adoption, which allows for the application of the standard solely to the transition period in 2019 but does not require application to prior fiscal comparative periods presented. The Company also elected the practical expedient provided in a subsequent amendment to ASU 2016-02 that removed the requirement to separate lease and non-lease components. The Company did not record a significant cumulative catch-up adjustment upon the adoption of ASC 2016-02. The primary impact was related to the Company's 22 operating ground leases and 2 corporate facility leases under which it served as lessee as of the adoption on ASU 2016-02 ondate. The Company recognized lease liabilities totaling $104,863 and right-of-use assets related to operating leases totaling $95,506 as of the adoption date.

In MarchJune 2016, the FASB issued ASU 2016-05, 2016-13, "DerivativesFinancial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments." ASU 2016-13 changes how entities measure credit losses for most financial assets.

Thecollected on the financial asset. In November 2018, the FASB issued ASU 2018-19, "Codification Improvements to Topic 326, Financial Instruments - Credit Losses," which clarified that receivables arising from operating leases are within the scope of the leasing standard (ASU 2016-02), and not within the scope of ASU 2016-13.

ASU 2020-06 simplifies several aspects of the accounting for employee share-based payment transactions, including the income tax consequences, classification of awards as eitherconvertible instruments and contracts in an entity's own equity, or liabilities, and classification on the statement of cash flows. Thisamended related earnings per share guidance. The guidance in ASU is2020-06 becomes effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The Company adopted this guidance prospectively on January 1, 2017, and prior periods have not been adjusted. As a result of2021. Early adoption is permitted no earlier than the adoption of this guidance, the Company no longer presents the tax effects from vesting of restricted stock grants and stock option exercises on its condensed consolidated statement of noncontrolling interests and equity.
In August 2016, the FASB issued ASU 2016-15, "Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments." ASU 2016-15 provides guidance on several specific cash flow issues, including the classification of debt prepayment or debt extinguishment costs, contingent consideration payments, and distributions received from equity method investees. This guidance is effective for fiscal years beginning after December 15, 2017.2020. The guidance may be adopted on a modified or fully retrospective basis.

In January 2017, the FASB issued ASU 2017-01, "Business Combinations (Topic 805) - Clarifying the Definition of a Business," which provides guidance on whether transactions should be accounted for as acquisitions or disposals of assets or businesses. Specifically, when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. Additionally, ASU 2017-01 also provides other guidance providing a more robust framework to use in determining whether a set of assets and activities is a business. This guidance is effective for annual periods beginning after December 15, 2017. Early application of ASU 2017-01 is permitted for transactions for which the acquisition or disposition date occurs before the issuance date or effective date of the amendments, only when the transaction has not been reported in financial statements that have been issued. The Company adopted the guidance in ASU 2017-01 to new acquisitions beginning on January 1, 2017. The adoption of this guidance resulted in a decrease in acquisition related costs, as the Company's acquisition of operating stores are considered asset acquisitions rather than business combinations under ASU 2017-01, and such costs are capitalized under the new guidance.
In August 2017, the FASB issued ASU 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements for Accounting for Hedging Activities," which amends and simplifies existing guidance for the financial reporting of hedging relationships to allow companies to better portray the economic effects of risk management activities in their financial statements. ASU 2017-12 is effective for annual periods beginning after December 15, 2018, with early adoption permitted. The Company plans to adopt ASU 2017-12 on January 1, 2018. ASU 2017-12 requires a modified retrospective transition method in which the Company will recognize the cumulative effect of the change on the opening balance of each affected component of equity in the consolidated balance sheets as of the date of adoption. The Company is currently assessing the impact of the adoption on ASU 2017-12 on the Company's consolidated financial statements.

WCOT created a new subsidiary, Extra Space Properties 132 LLC ("ESP 132") and transferred 11 stores into ESP 132. WCOT then distributed ESP 132 to the Company and Prudential on a pro rata basis. This distribution was accounted for as a spinoff, and was therefore recorded at the net carrying amount of the properties of $68,814. Immediately after the distribution, the Company acquired Prudential's 95.0% interest in ESP 132 for $153,304, resulting in 100% ownership of ESP 132 and the related 11 stores. Based on the purchase price of Prudential's share of ESP 132, the Company determined that the fair value of its investment in ESP 132 immediately prior to the acquisition of Prudential's share was $8,119, and the Company recorded a gain of $4,651 as a result of remeasuring to fair value its existing equity interest in ESP 132. This gain is included in equity in earnings of unconsolidated real estate ventures - gain on sale of real estate assets and purchase of joint venture partners' interests on the Company's consolidated statements of operations.

Losses on Earnouts from Prior Acquisitions
On December 2014, the Company acquired a portfolio of five stores located in New Jersey and Virginia. As part of this acquisition, the Company agreed to make an additional cash payment to the sellers if the acquired stores exceeded a specified amount of net operating income for the years ending December 31, 2015 and 2016. At the acquisition date, the Company recorded an estimated liability related to this earnout provision. The operating income of these stores during the earnout period was higher than expected, resulting in an increase in the estimate of the amount due to the sellers of $4,284, which was recorded as a loss and included in gain (loss) on real estate transactions, earnout from prior acquisitions and impairment of real estate on the Company's consolidated statements of operations for the year ended December 31, 2016.
During 2011, the Company acquired a store located in Florida. As part of this acquisition, the Company agreed to make an additional cash payment to the sellers if the acquired store exceeded a specified amount of net rental income for any twelve-month period prior to June 30, 2015. At the acquisition date, $133 was recorded as the estimated amount that would be due, and the Company believed that it was unlikely that any significant additional payment would be made as a result of this earnout provision. Because the rental growth of the stores was trending significantly higher than expected, the Company estimated that an additional earnout payment of $2,500 was due to the seller as of December 31, 2014. This amount is included in gain (loss) on real estate transactions, earnout from prior acquisitions and sale of other assets on the Company’s consolidated statements of operations for the year ended December 31, 2014. During the year ended December 31, 2015, the Company recorded a gain of $400 to adjust the existing liability to the actual amount owed to the sellers as of June 30, 2015.

To the extent that cash/cash or profits in excess of these preferred returns are generated through operations or capital transactions, the Company would receive a higher percentage of the excess cash/cash or profits, as applicable, than its equity interest.
The Company separately reports investments with net equity less than zero in cash distributions in unconsolidated real estate ventures in the consolidated balance sheets. The net equity of certain joint ventures is less than zero because distributions have exceeded the Company's investment in and share of income from these joint ventures. This is generally the result of financing distributions, capital events or operating distributions that are usually greater than net income, as net income includes non-cash charges for depreciation and amortization while distributions do not.

7.8.     DERIVATIVES
The Company is exposed to certain risk arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk primarily by managing the amount, sources and duration of its debt funding and the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company’s derivative financial instruments are used to manage differences in the amount, timing and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally related to the Company’s investments and borrowings.

Cash Flow Hedges of Interest Rate Risk
The Company’s objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount.
The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive income (“OCI”) and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. A portion of these changes is excluded from accumulated other comprehensive income as it is allocated to noncontrolling interests. During the years ended December 31, 2017, 20162020, 2019 and 2015,2018, such derivatives were used to hedge the variable cash flows associated with existing variable-rate debt. During 2018,2021, the Company estimates that $4,736$35,080 will be reclassified as a decreasean increase to interest expense.
The following table summarizes the terms of the Company’s 2922 derivative financial instruments, which have a total combined notional amount of $2,154,799$2,091,270 as of December 31, 2017:2020:

Credit-Risk-Related Contingent Features
The Company has agreements with some of its derivative counterparties that contain provisions pursuant to which, the Company could be declared in default of its derivative obligations if the Company defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender.
The Company also has an agreement with some of its derivative counterparties that incorporates the loan covenant provisions of the Company’s indebtedness with a lender affiliate of the derivative counterparty. Failure to comply with the loan covenant provisions would result in the Company being in default on any derivative instrument obligations covered by the agreement.

12.     NONCONTROLLING INTEREST REPRESENTED BY PREFERRED OPERATING PARTNERSHIP UNITS
Classification of Noncontrolling Interests
GAAP requires a company to present ownership interests in subsidiaries held by parties other than the company in the consolidated financial statements within the equity section, but separate from the company’s equity. It also requires the amount of consolidated net income attributable to the parent and to the noncontrolling interest to be clearly identified and presented on the face of the consolidated statement of operations and requires changes in ownership interest to be accounted for similarly as equity transactions. If noncontrolling interests are determined to be redeemable, they are to be carried at their redemption value as of the balance sheet date and reported as temporary equity.
The Company has evaluated the terms of the Operating Partnership’s preferred units and classifies the noncontrolling interest represented by such preferred units as stockholders’ equity in the accompanying consolidated balance sheets. The

Any noncontrolling interests that fail to qualify as permanent equity will be reclassified as temporary equity and adjusted to the greater of (1) the carrying amount, or (2) its redemption value as of the end of the period in which the determination is made.

As of December 31, 2017, the noncontrolling interests represented by Operating Partnership preferred units consisted of the following:
875,480 Series A Units;
1,676,087 Series B Units;

On April 18, 2017, a loan amendment was signed modifying the maturity date of the loan to the later of the death of the Series A Unit holder or his spouse and also lowering the interest rate of the loan from 4.9% to 2.1%. The loan amendment was determined to be a loan modification under GAAP, and therefore no change in value was recognized. The loan is secured by the borrower’s Series A Units. NoNaN future redemption of Series A Units can be made unless the loan secured by the Series A Units is also repaid. The Series A Units are shown on the balance sheet net of the $100,000 loan because the borrower under the loan is also the holder of the Series A Units.

Any noncontrolling interests that fail to qualify as permanent equity will be reclassified as temporary equity and adjusted to the greater of (1) the carrying amount, or (2) its redemption value as of the end of the period in which the determination is made.
14.     OTHER NONCONTROLLING INTERESTSOther Noncontrolling Interests
Other noncontrolling interests represent the ownership interest of third parties in two2 consolidated joint ventures as of December 31, 2017.2020. One joint venture owns an operating store2 stores in Texas and a development store in Texas. and a development store2 stores in Colorado, and the other owns a development propertystore in Pennsylvania.Pennsylvania and a store in New Jersey. The voting interests of the third-party owners are between 5.0% and 20.0%.
14.    LEASES

The Company adopted ASC 842, "Leases," effective January 1, 2019 on a modified retrospective basis as allowed under the standard and thus prior periods have not been restated. The Company elected the package of transition practical expedients, and has therefore (1) not reassessed whether any expired or existing contracts are or contain leases, (2) not reassessed the lease classification for any expired or existing leases, and (3) not reassessed initial direct costs for any expired or existing leases.
Lessee Accounting
The Company recognized right-of-use assets related to operating leases totaling $95,506 and lease liabilities of $104,863 as of the adoption date, January 1, 2019. These are presented as “Operating lease liabilities” and “Real estate assets-operating lease right-of-use assets” on the Company’s consolidated balance sheets. Right-of-use assets associated with finance leases are included in real estate assets, net and finance lease liabilities are included in other liabilities on the Company's consolidated balance sheets.
During the year ended December 31, 2020, the Company recorded new finance lease right-of-use assets and finance lease liabilities totaling $41,491 associated with the acquisition of 3 stores with land leases. The Company also recorded finance lease right-of-use assets and finance lease liabilities of $8,605 upon the completion of construction of a store with a land lease.
In June and August 2019, the Company entered into new triple-net lease agreements to lease land and buildings at 22 and 5 operating stores, respectively. These leases are categorized as operating leases, and have contractual lease terms of 25 years, but have termination options after 10 years that result in lease terms of 10 years under ASC 842. The Company recorded new operating lease right-of-use assets and operating lease liabilities of $127,532 and $52,224, respectively, in conjunction with these new lease agreements.
The Company is lessee under several types of lease agreements. Generally, these leases fall into the following categories:
Leases of real estate at 53 stores classified as wholly-owned or in consolidated joint ventures. These leases generally have original lease terms between 10-99 years. Under these leases, the Company typically has the option to extend the lease term for additional terms of 5-35 years.
Leases of its corporate offices and call center. These leases have original lease terms between 5.3 and 12.1 years, with no extension options. Subsequent to year-end the Company modified and extended the lease of its corporate offices to add additional space and extend the lease until 2034.
Leases of 13 regional offices. These leases have original lease terms between three and five years. The Company has the option on certain of these leases to extend the lease term for up to three additional years.
Leases of small district offices. These leases generally have terms of 12 months or less. The Company has made an election to account for these under the short-term lease exception outlined under ASC 842. Therefore, no lease assets or liabilities are recorded related to these leases.

The Company has included lease extension options in the lease term for calculations of its right-of-use assets and liabilities related to the real estate asset leases at its stores when it is reasonably certain that the Company plans to extend the lease terms as the options arise.

Several of the leases of real estate at the Company’s stores include escalation clauses based on an index or rate, such as the Consumer Price Index (CPI). The Company included these lease payments in its calculations of right-of-use assets and

liabilities based on the prevailing index or rate as of the adoption date. The Company will recognize changes to these variable lease payments in earnings in the period of change.
One of the real estate leases includes variable lease payments that are based upon a percentage of gross revenues. Certain other leases include additional variable payments relating to a percentage of sales in excess of a specified amount, common area maintenance, property taxes, and similar items. These payments are variable lease payments that do not depend on an index or rate and are excluded from the measurement of the lease liabilities and right-of-use-assets for these leases. The Company will recognize costs from these variable lease payments in the period in which the obligation for those payments is incurred.
The Company has a signed lease agreement for a store in California. The store is under construction by the lessor, and the Company will take possession of the leased asset upon completion of construction, which is estimated to be completed in mid- 2021. The lease term is 15 years from the lease commencement date, with 3 10-year extension options and 1 5-year extension option. The Company has not recorded right-of-use asset or lease liability related to this lease as of December 31, 2020 as the lease term has not yet commenced. The lease commencement date will occur when the Company takes possession of the leased asset, and the Company will recognize a lease liability and right-of-use asset relating to the lease at that time.
As the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available surrounding the Company’s unsecured borrowing rates and implied secured spread at the lease commencement date in determining the present value of lease payments. These discount rates vary depending on the term of the specific leases.

Lessor Accounting

The Company's property rental revenue is primarily related to rents received from tenants at its operating stores. The Company's leases with its self-storage tenants are generally on month-to-month terms, include automatic monthly renewals, allow flexibility to increase rental rates over time as market conditions permit, and provide for the collection of contingent fees such as late fees. These leases do not include any terms or conditions that allow the tenants to purchase the leased space. All self-storage leases for which the Company acts as lessor have been classified as operating leases. The real estate assets related to the Company's stores are included in "Real estate assets, net" on the Company's condensed consolidated balance sheets and are presented at historical cost less accumulated depreciation and impairment, if any. Rental income related to these operating leases is included in Property rental revenue on the Company's condensed consolidated statements of operations, and is recognized each month during the month-to-month terms at the rental rate in place during each month.
15.     STOCK-BASED COMPENSATION

As ofDecember 31, 20172020, 1,653,8551,239,557 shareswere available for issuance under the Company’s 2015 Incentive Award Plan (the “Plan”).
Option grantsOptions are issued with an exercise price equal to the closing price of stock on the date of grant. Unless otherwise determined by the Compensation, Nominating and Governance Committee (“CNG Committee”) at the time of grant, options shall vest ratably over a four-year period beginning on the date of grant. Each option will be exercisable once it has vested. Options are exercisable at such times and subject to such terms as determined by the CNGCompensation Committee, but under no circumstances may be exercised if such exercise would cause a violation of the ownership limit in the Company’s charter. Options expire 10 years from the date of grant. Beginning in 2017, the CNG Committee decided to the replace stock options granted to executives with performance based stock units for executive compensation. See the "Performance-Based Stock Units" section below.
Also as defined under the terms of the Plan, restricted stock grants may be awarded. The stock grants are subject to a vesting period over which the restrictions are released and the stock certificates are given to the grantee. During the performance or vesting period, the grantee is not permitted to sell, transfer, pledge, encumber or assign shares of restricted stock granted under the Plan; however, the grantee has the ability to vote the shares and receive nonforfeitable dividends paid on shares. Unless otherwise determined by the CNGCompensation Committee at the time of grant, the forfeiture and transfer restrictions on the shares lapse over a four-year period beginning on the date of grant.

The forfeiture rate, which is estimated at a weighted-average of 7.4% of unvested options outstanding as of December 31, 2017,2020, is adjusted periodically based on the extent to which actual forfeitures differ, or are expected to differ, from the previous estimates.

Performance-based Stock Units
In 2017, the CNG Committee changed its compensation for executives to issue performance-based stock units (the "PSUs") as a replacement for stock option awards. The PSUs granted to executives in March 2017 represent the right to earn shares of the Company's common stock. These awards have two financial performance components: (1) the Company's core FFO performance ("FFO Target"), and (2) the Company's total stockholder return relative to the performance of a defined group of peers ("TSR Target"). Each of these performance components are weighted 50% and are measured over the performance period, which is defined as the three-year period ending December 31 2019.from the year of grant. At the end of the performance period, the financial performance components are reviewed to determine the number of shares actually granted to executives, which can be as low as zero0 shares and up to a maximum of two2 shares issued for each PSU. A summary of the PSU activity is as follows:

The Company estimated the fair value of the PSUs as of the grant date, using the closing trading price of the Company's common stock on the grant date to value the FFO Target portion. A Monte Carlo simulation model was used to calculate the fair value of the TSR Target portion of the PSUs, using an expected term of 2.8 years, a risk-free rate of 1.6%,the following assumptions:

Under the terms of the PSUs, dividends for the entire measurement period are paid in cash when the shares are issued,released, so a dividend yield of zero0 was used. The Monte Carlo simulation model incorporates assumptions to value stock-based awards. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of the grant for the estimated life of the PSUs.
Compensation cost is recognized ratably over the period from the date of grant to the end of the related performance period. The Company recognized compensation expense of $840 during the year ended December 31, 2017 related to the PSUs, which is included in general and administrative expense in the Company's consolidated statements of operations. The intrinsic value of unvested PSUs as of December 31, 2017 was $2,630.
As of December 31, 2017, there was $1,681 of total unrecognized compensation expense related to the PSUs under the Plan. That cost is expected to be recognized over a period of two years. The valuation model applied in this calculation utilizes subjective assumptions that could potentially change over time, including the probabilities associated with achieving the FFO Targets (categorized within Level 3 of the fair value hierarchy). Therefore, the amount of unrecognized compensation expense at December 31, 20172020 noted above does not necessarily represent the expense that will ultimately be realized by the Company in the statement of operations.

The Company has a retirement savings plan under Section 401(k) of the Internal Revenue Code under which eligible employees can contribute up to 60% of their annual salary, subject to a statutory prescribed annual limit. For the years ended December 31, 2017, 20162020, 2019 and 2015,2018, the Company made matching contributions to the plan of $2,212, $1,944$3,980, $3,355 and $1,680,$2,833, respectively, based on 100% of the first 3% and up to 50% of the next 2% of an employee’s compensation.
17.     INCOME TAXES
As a REIT, the Company is generally not subject to U.S. federal income tax with respect to that portion of its income which is distributed annually to its stockholders. However, the Company has elected to treat onecertain of its corporate subsidiaries, including Extra Space Management, Inc., as a taxable REIT subsidiary.TRS. In general, the Company’sa 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.tax and may be subject to state and local income taxes. The Company accounts for income taxes in accordance with the provisions of ASC 740, “Income Taxes.” Deferred tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities. The Company has elected to use the Tax-Law-Ordering approach to determine when excess tax benefits will be realized.

The state income tax net operating losses expire between 20182021 and 2035.2038. The valuation allowance is associated with the state income tax net operating losses. The tax years 20132016 through 20162019 remain open related to the state returns, and 20142017 through 20162019 for the federal returns.
Federal tax reform legislation that was enacted on December 22, 2017 (commonly known as the Tax Cuts and Jobs Act) (the “2017 Tax Legislation”) made substantial changes to the Internal Revenue Code. Among those changes are a reduction in the U.S. federal corporate tax rate from the previous rate of 35% to 21%, the elimination or modification of various currently allowed deductions, and a deduction for REIT stockholders that are individuals, trusts and estates of up to 20% of ordinary REIT dividends. Many of the provisions of the 2017 Tax Legislation will require guidance through the issuance of Treasury regulations in order to assess their effect. There may be a substantial delay before such regulations are issued, increasing the uncertainty as to the ultimate effect of the statutory amendments on the Company. It is also likely that there will be technical corrections legislation proposed with respect to the 2017 Tax Legislation, the effect of which cannot be predicted and may be adverse to the Company or its stockholders.
67
The SEC staff issued SAB 118, which provides guidance on accounting for the tax effects of the 2017 Tax Legislation. SAB 118 provides a measurement period that should not extend beyond one year from the Act enactment date for companies to complete the accounting under ASC 740. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the 2017 Tax Legislation.

The Company remeasured certain deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future, which is generally 21%. However, the Company is still analyzing certain aspects of the 2017 Tax Legislation and refining calculations, which could potentially affect the measurement of these balances or potentially give rise to new deferred tax amounts. The tax benefit recorded related to the remeasurement of the deferred tax balance and valuation allowance was $8,606, which is included as a component of income tax expense.

The impact of the 2017 Tax Legislation may differ from the Company’s estimates, possibly materially, due to, among other things, changes in interpretations and assumptions the Company has made, guidance that may be issued and actions the Company may take as a result of the 2017 Tax Legislation. The Company will continue to make and refine calculations as additional analysis is completed. In addition, the estimates may also be affected as the Company gains a more thorough understanding of the tax law.
18.     SEGMENT INFORMATION


The Company’s segment disclosures present the measure used by the chief operating decision makers ("CODMs") for purposes of assessing each segment’s performance. The Company’s CODMs are comprised of several members of its executive management team who use net operating income ("NOI") to assess the performance of the business for the Company’s reportable operating segments. NOI for our self-storage operations represents total property revenue less direct property operating expenses. NOI for our tenant reinsurance segment represents tenant reinsurance revenues less tenant reinsurance expense.


The Company’s segments were historicallyare comprised of three reportable segments: (1) rental operations; (2) tenant reinsurance; and (3) property management, acquisition and development. Based on how the CODMs reviews performance and makes decisions, the Company realigned its segments into two2 reportable segments: (1) self-storage operations and (2) tenant reinsurance. The self-storage operations activities include rental operations of wholly-owned stores. The Company's consolidated revenues equal total segment revenues plus property management fees and other income. Tenant reinsurance activities include the reinsurance of risks relating to the loss of goods stored by tenants in the stores operated by the Company. Excluded from segment revenues and net operating income is property management fees and other income.


For all periods presented, substantially all of our real estate assets, intangible assets, other assets, and accrued and other liabilities are associated with the self-storage operations segment. The prior periods have been restated to conform to the current presentation. Financial information for the Company’s business segments is set forth below:

The Company is involved in various legal proceedings and is 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. Therefore, any estimate(s) of loss disclosed below represents what management believes to be an estimate of loss only for certain matters meeting these criteria and does not represent the Company's maximum loss exposure. The Company could in the future incur judgments or enter into settlements of claims that could have a material adverse effect on its results of operations in any particular period, notwithstanding the fact that the Company is currently vigorously defending any legal proceedings against it. As of December 31, 2017,2020, the Company was involved in various legal proceedings and was subject to various claims and complaints arising in the ordinary course of business. In the opinion of

management, such litigation, claims and complaints are not expected to have a material adverse effect on the Company’s financial condition or results of operations.
As of December 31, 2017, the Company was under agreement to acquire 14 stores at a total purchase price of $190,222. Of these stores, ten are scheduled to close in 2018 at a purchase price of $141,294, three are scheduled to close in 2019 at a purchase price of $38,400, and one is scheduled to close thereafter at a purchase price of $10,528. Additionally, the Company is under agreement to acquire 17 stores with joint venture partners, for a total investment of $88,203. Fourteen of these stores are scheduled to close in 2018, while the remaining three stores are expected to close in 2019.
The Company owns and/or operates stores located in Texas, Florida, and Puerto Rico that were impacted by Hurricanes Harvey, Irma, and Maria during the year ended December 31, 2017. Losses incurred to date by these hurricanes include property damage, net of insurance recoveries, of $2,110, and tenant reinsurance claims of $2,250, which are included in property operations and tenant reinsurance on the Company's condensed consolidated statements of operations.
Although there can be no assurance, the Company is not aware of any material environmental liability, for which it believes it will be ultimately responsible, that could have a material adverse effect on its financial condition or results of operations. However, changes in applicable environmental laws and regulations, the uses and conditions of properties in the vicinity of the Company’s properties, the activities of its tenants and other environmental conditions of which the Company is unaware with respect to its properties could result in future material environmental liabilities.

Item 9A.     Controls and Procedures
(i)Disclosure Controls and Procedures
(i)Disclosure Controls and Procedures
We maintain disclosure controls and procedures to ensure that information required to be disclosed in the reports we file pursuant to the Securities Exchange Act of 1934, as amended (the “Exchange Act”), are recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure based on the definition of “disclosure controls and procedures” in Rule 13a-15(e) of the Exchange Act. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can only provide reasonable assurance of achieving the desired control objectives, and in reaching a reasonable level of assurance, management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.
We have a disclosure committee that is responsible for considering the materiality of information and determining the disclosure obligations of the Company on a timely basis. The disclosure committee meets quarterly and reports directly to our Chief Executive Officer and Chief Financial Officer.
We carried out an evaluation, under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this Annual Report. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of the end of the period covered by this report.

(1)Management’s Report on Internal Control over Financial Reporting
    
Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a-15(f) of the Exchange Act. Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework). Based on our evaluation, our management concluded that our internal control over financial reporting was effective as of December 31, 2017.2020. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Our independent registered public accounting firm, Ernst & Young LLP, has issued the following attestation report over our internal control over financial reporting.

In our opinion, Extra Space Storage, Inc. (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017,2020, based on the COSO criteria.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 20172020 and 2016, and2019, the related consolidated statements of operations, comprehensive income, stockholders’stockholders' equity and cash flows for each of the three years in the period

ended December 31, 2017,2020, and the related notes and financial statement schedule listed in the Index at Item 8 and our report dated March 1, 2018February 26, 2021 expressed an unqualified opinion thereon.
Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the company’sCompany’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.
Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control Over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
