General

Public Storage (referred to herein as “the Company”, “we”, “us”, or “our”), a Maryland REIT, was organized in 1980.

At December 31, 2019, our principal business activities were as follows:

(i)Self-storage Operations: We acquire, develop, own and operate self-storage facilities, which offer storage spaces for lease on a month-to-month basis, for personal and business use. We are the largest owner and operator of self-storage facilities in the U.S. At December 31, 2019, we have direct and indirect equity interests in 2,483 self-storage facilities that we consolidate (an aggregate of 169 million net rentable square feet of space) located in 38 states within the U.S. operating under the “Public Storage” brand name.

(ii)Ancillary Operations: We reinsure policies against losses to goods stored by customers in our self-storage facilities and sell merchandise, primarily locks and cardboard boxes, at our self-storage facilities.

(iii)Investment in PS Business Parks: We have a 42% equity interest in PS Business Parks, Inc. (“PSB”), a publicly held REIT that owns, operates, acquires and develops commercial properties, primarily multi-tenant flex, office, and industrial parks. At December 31, 2019, PSB owns and operates 27.6 million rentable square feet of commercial space.

(iv)Investment in Shurgard: We have a 35% equity interest in Shurgard Self Storage SA (“Shurgard”), a public company traded on Euronext Brussels under the “SHUR” symbol, which owns 234 self-storage facilities (13 million net rentable square feet) located in seven countries in Western Europe operated under the “Shurgard” brand name. We believe Shurgard is the largest owner and operator of self-storage facilities in Western Europe.

We also manage 55 self-storage facilities for third parties as of December 31, 2019. In order to further increase our economies of scale and leverage our brand, in 2018 we began an effort to expand the number of facilities we manage, through a dedicated internal sales, administration, and implementation team. During the year ended December 31, 2019, we added 22 facilities to our third party management platform. At December 31, 2019, we are under contract to manage 27 additional facilities, currently under construction, following their completion. It is uncertain how many third party managed facilities we will add to our platform over time. We also own 0.9 million net rentable square feet of commercial space which is managed primarily by PSB.

For all periods presented herein, we have elected to be treated as a REIT, as defined in the Internal Revenue Code of 1986, as amended (the “Code”). As a REIT, we do not incur U.S. federal income tax if we distribute 100% of our “REIT taxable income” (generally, net rents and gains from real property, dividends, and interest) each year (for this purpose, certain distributions paid in a subsequent year may be considered), and if we meet certain organizational and operational rules. We believe we met these requirements in all periods presented herein and we expect to continue to elect and qualify as a REIT.

We report annually to the SEC on Form 10-K, which includes financial statements certified by our independent registered public accountants. We also report quarterly to the SEC on Form 10-Q, which includes unaudited financial statements. We expect to continue such reporting.

On our website, www.publicstorage.com, we make available, free of charge, our Annual Reports on Form 10- K, quarterly reports on Form 10-Q, current reports on Form 8-K, and all amendments to those reports as soon as reasonably practicable after the reports and amendments are electronically filed with or furnished to the SEC. The information contained on our website is not a part of, or incorporated by reference into, this Annual Report on Form 10-K.

Competition

We believe that our customers generally store their goods within a three to five mile radius of their home or business. Our facilities compete with nearby self-storage facilities owned by other operators using marketing channels similar to ours, including Internet advertising, signage, and banners and offer services similar to ours. As a result, competition is significant and affects the occupancy levels, rental rates, rental income and operating expenses of our facilities.

In the last three years, there has been a marked increase in development of new self-storage facilities in many of the markets where we operate, due to the favorable economics of developing new properties. These newly developed facilities compete with many of the facilities we own, negatively impacting our occupancies, rental rates, and rental growth. This increase in supply has been most notable in Atlanta, Austin, Charlotte, Chicago, Dallas, Denver, Houston, Miami, New York, and Portland.

Ownership and operation of self-storage facilities is highly fragmented. As the largest owner of self-storage facilities, we believe that we own approximately 7% of the self-storage square footage in the U.S. and that collectively the five largest self-storage owners in the U.S. own approximately 16%, with the remaining 84% owned by regional and local operators.

The high level of ownership fragmentation in the industry is partially attributable to the relative simplicity of managing a local self-storage facility, such that small-scale owners can operate self-storage facilities at a basic level of profitability without significant managerial or operational infrastructure. However, we believe that the economies of scale inherent in this business result in our being able to operate self-storage facilities at a materially higher level

of cash flow per square foot than other operators without our scale. See “Business Attributes” below for further discussion of these economies of scale.

While this fragmentation offers us opportunities to acquire additional facilities over time, and our scale allows us to extract more cash flow from the properties we acquire, we compete for facilities that are marketed for sale with a wide variety of institutions and other investors who also view self-storage facilities as attractive investments. The amount of capital available for real estate investments greatly influences the competition for ownership interests in facilities and, by extension, the yields that we can achieve on newly acquired investments.

Recently, larger national operators (including ourselves) are offering to manage facilities owned by third parties on their platform for a fee (“Third Party Management”), and Google is offering a more convenient platform for small operators to compete with larger operators in paid search bidding campaigns to drive web traffic and increase reservations. These two developments have the potential to diminish the competitive advantage we have versus smaller owner/operators. The extent to which this trend becomes impactful is dependent on (i) how many smaller operators will choose to avail themselves of Third Party Management, (ii) the extent to which large national operators seek to increase the number of properties under Third Party Management and (iii) the extent to which smaller operators are attracted to Google’s marketing platform and are able to improve the efficacy of their marketing.

We generally own facilities in major markets. We believe that we have significant market share and concentration in major metropolitan centers, with approximately 70% of our 2019 same-store revenues generated in the 20 Metropolitan Statistical Areas (each, an “MSA”, as defined by the U.S. Census Bureau) with the highest population levels. We believe this is a competitive advantage relative to other self-storage operators, which do not have our geographic concentration and market share in the major MSAs.

Business Attributes

We believe that we possess several primary business attributes that permit us to compete effectively:

Centralized information networks: Our centralized reporting and information network enables us to identify changing market conditions and operating trends as well as analyze customer data and, on an automated basis, quickly change each of our individual properties’ pricing and promotions, as well as to drive marketing spending such as the relative level of bidding for various paid search terms on paid search engines.

Convenient shopping experience: Customers can conveniently shop for available storage space, reviewing attributes such as facility location, size, amenities such as climate-control, as well as pricing, through the following marketing channels:

Our Desktop and Mobile Websites: The online marketing channel is a key source of customers. Approximately 75% of our move-ins in 2019 were sourced through our website and we believe that many of our other customers who reserved directly through our call center or arrived at a facility and moved in without a reservation, have reviewed our pricing and availability online through our websites. We seek to regularly update the structure, layout, and content of our website in order to enhance our placement in “unpaid” search in Google and related websites, to improve the efficiency of our bids in “paid” search campaigns, and to maximize users’ likelihood of reserving space on our website.

Our Call Center: Our call center is staffed by skilled sales specialists. Customers reach our call center by calling our advertised toll-free telephone numbers provided on search engines or our website. We believe giving customers the option to interact with a call center agent, despite the higher marginal cost relative to a reservation made on our website, enhances our ability to close sales with potential customers.

Our Properties: Customers can also shop at any one of our facilities. Property managers access the same information that is available on our website and to our call center agents, and can inform

the customer of available space at that site or our other nearby storage facilities. Property managers are trained to maximize the conversion of such “walk in” shoppers into customers.

Managerial economies of scale: The size and scope of our operations have enabled us to achieve high operating margins and a low level of administrative costs relative to revenues through the centralization of many functions, such as facility maintenance, employee compensation and benefits programs, revenue management, as well as the development and documentation of standardized operating procedures. We also believe that our major market concentration provides managerial efficiencies stemming from having a large percentage of our facilities in close proximity to each other.

Marketing economies of scale: Our major-market concentration relative to the fragmented ownership and operation of the rest of the industry, combined with our well-recognized brand name, improves our prominence in unpaid online search results for self-storage and reduces our average cost per “click” for multiple-keyword advertising. Such concentration and the resulting volume enables us to efficiently leverage systematic bidding strategies to maximize our return on investment across multiple keywords.

Brand name recognition: We believe that the “Public Storage” brand name is the most recognized and established name in the self-storage industry, due to our national reach in major markets in 38 states, our highly visible facilities, and our facilities’ distinct orange colored doors and signage. We believe the “Public Storage” name is one of the most frequently used search terms used by customers using Internet search engines for self-storage. We believe that the “Shurgard” brand, used by Shurgard, is a well-established and valuable brand in Europe. We believe that the awareness of our brand name results in a high percentage of potential storage customers considering our facilities relative to other operators.

Growth and Investment Strategies

Our ongoing growth strategies consist of: (i) improving the operating performance of our existing self-storage facilities, (ii) acquiring more facilities, (iii) developing new facilities and adding more self-storage space to our existing facilities, (iv) participating in the growth of our investment in PSB, and (v) participating in the growth of our investment in Shurgard. While our long-term strategy includes each of these elements, in the short run the level of growth in our asset base in any period is dependent upon the cost and availability of capital, as well as the relative attractiveness of available investment alternatives.

From time to time we explore expansion of our activities to other countries. Any such strategic expansion would most likely involve acquiring an interest in an existing operator’s platform. There can be no assurance that any such expansion will occur in the future or the timing thereof.

Improve the operating performance of existing facilities: We seek to increase the net cash flow of our existing self-storage facilities through maximizing revenues and controlling operating costs. We seek to maximize revenues through striking the appropriate balance between occupancy and rates to new and existing tenants, by regularly adjusting (i) our promotional and other discounts, (ii) the rental rates we charge to new and existing customers, and (iii) our marketing spending and intensity. We inform these pricing and marketing decisions by observing their impact on web and call center traffic, reservations, move-ins, move-outs, tenant length of stay, and other indicators of response. We also seek to control operating costs and provide a favorable experience to new, existing, and potential customers by leveraging information technology and our economies of scale, effectively overseeing our customer-facing and back-office property management personnel, and by providing convenient shopping options for the customer.

Acquire properties owned by others in the U.S.: We seek to capitalize on the fragmentation of the self-storage business through acquiring attractively priced, well-located existing self-storage facilities. We believe our presence in and knowledge of substantially all of the major markets in the U.S. enhances our ability to identify attractive acquisition opportunities. Data on the rental rates and occupancy levels of our existing facilities provide us an advantage in evaluating the potential of acquisition opportunities. Our aggressiveness in bidding for particular marketed facilities depends upon many factors including the potential for future growth, the quality of construction and location, the cash flow we expect from the facility when operated on our platform, how well the facility fits into

our current geographic footprint, as well as our return on capital expectations. From January 1, 2015 through December 31, 2019, we acquired an aggregate of 163 facilities from third parties at an aggregate cost of $1.4 billion. We will continue to seek to acquire properties in 2020; however, there is significant competition to acquire existing facilities, and self-storage owners’ desire to sell is based upon many variables, including potential reinvestment returns, expectations of future growth, estimated value, the cost of debt financing, as well as personal considerations. As a result, there can be no assurance as to the level of facilities we may acquire.

Develop new self-storage facilities and expand existing facilities: The development of new self-storage locations and the expansion of existing facilities has been an important source of growth. Since the beginning of 2013, we have expanded our development efforts due in part to the significant increase in prices being paid for existing facilities, in many cases well above the cost of developing new facilities. At December 31, 2019, we had a development pipeline to develop 12 new self-storage facilities and expand 35 existing self-storage facilities, which will add approximately 4.4 million net rentable square feet, at a cost of $619.2 million. Some of these projects are subject to significant contingencies such as entitlement approval. We expect to continue to seek additional development projects; however, the level of future development may be limited due to various constraints such as difficulty in finding projects that meet our risk-adjusted yield expectations, challenges in obtaining building permits for self-storage activities in certain municipalities, as well as challenges in sourcing quality construction materials, labor, and design elements.

Participate in the growth of PS Business Parks, Inc.: Our investment in PSB provides diversification into another asset type. PSB is a stand-alone public company traded on the NYSE. As of December 31, 2019, we have a 42% equity interest in PSB.

PSB seeks to grow its asset base in its existing markets as well as increase the cash flows from its owned portfolio. As of December 31, 2019, PSB owned and operated approximately 27.6 million rentable square feet of commercial space, and had an enterprise value of approximately $6.7 billion (based upon the trading price of PSB’s common stock combined with the liquidation value of its preferred stock as of December 31, 2019).

Participate in the growth of Shurgard: We believe Shurgard is the largest self-storage company in Western Europe. It owns and operates 234 self-storage facilities with approximately 13 million net rentable square feet in: France (principally Paris), Sweden (principally Stockholm), the United Kingdom (principally London), the Netherlands, Denmark (principally Copenhagen), Belgium (principally Brussels) and Germany. On October 15, 2018, Shurgard completed an initial global offering (the “Offering”) of 25.0 million of its common shares for €575 million in gross proceeds, and its shares commenced trading on Euronext Brussels under the “SHUR” symbol. As a result of the Offering (we did not acquire any additional common shares or sell any of our existing shares in the Offering), our equity interest in Shurgard decreased from 49% to 35.2%.

Customer awareness and availability of self-storage is significantly lower in Europe than in the U.S. However, with more awareness and product supply, we believe there is potential for increased demand for storage space in Europe. We believe Shurgard can capitalize on potential increased demand through the development of new facilities and acquiring existing facilities. From January 1, 2014 through December 31, 2019, Shurgard acquired 39 facilities from third parties for approximately $398.1 million, and has opened 10 development properties at a total cost of approximately $122.9 million. At December 31, 2019, Shurgard had contracts to acquire six properties and had six properties under development.

Financial Profile and Sources of Growth Capital

Capital Constraints as a REIT: While being a REIT allows us to minimize the payment of federal and state income tax expense, we are required to distribute 100% of our taxable income to our shareholders. This requirements limits cash flow from operations that can be retained and reinvested in the business, increasing our reliance upon raising capital to fund growth.

Access to Capital: Because raising capital is important to our growth, we endeavor to maintain a strong financial profile characterized by strong credit metrics, including low leverage relative to our total capitalization and operating cash flows. We are one of the highest rated REITs, as rated by major rating agencies Moody’s and Standard

& Poor’s. Our senior debt has an “A” credit rating by Standard & Poor’s and “A2” by Moody’s. Our credit ratings on each of our series of preferred shares are “A3” by Moody’s and “BBB+” by Standard & Poor’s. Our credit profile and ratings enable us to effectively access both the public and private capital markets to raise capital.

While we must distribute our taxable income, we are nonetheless able to retain operating cash flow to the extent that our tax depreciation exceeds our maintenance capital expenditures. In recent years, we have retained approximately $200 million to $300 million per year in cash flow. Capital needs in excess of retained cash flow are met with: (i) preferred equity, (ii) medium and long-term debt, and (iii) common equity. We select among these sources of capital based upon relative cost, availability, the desire for leverage, and potential constraints caused by certain features of capital sources, such as debt covenants. We view our line of credit, as well as short-term bank loans, as bridge financing.

We could also raise capital through joint venture financing or the sale of properties, however, we have no current plans to use these sources of capital.

Preferred equity: Preferred equity is an important source of long-term capital. While preferred equity’s coupon rates generally exceed interest rates on long-term debt, we believe the issuance of preferred equity is a favorable source of capital when available because it does not require repayment and, at our option, we can redeem the security after five years if, for example, market coupon rates have declined and we can reissue new securities at a lower rate.

Notwithstanding these favorable characteristics, the rates and market conditions for the issuance of preferred securities can be volatile or inefficient from time to time, and the amount that can be issued in any particular offering is generally limited to approximately $300 million at any one point in time, because demand for these securities comes primarily from retail investors rather than institutional investors.

The level of preferred equity outstanding has remained relatively constant, totaling $4.3 billion at December 31, 2014 and $4.1 billion at December 31, 2019. However, during this timeframe, we have regularly redeemed preferred shares pursuant to our redemption option, and issued new preferred equity at lower rates, reducing the average coupon rate from 5.88% at December 31, 2014 to 5.12% at December 31, 2019.

As of February 25, 2020, we believe that the market coupon rate for preferred securities approximates 4.75%. As of February 25, 2020, we have the option to redeem, with 30 days’ notice, the following series of preferred securities: our 5.375% Series V Preferred Shares ($495 million), our 5.200% Series W Preferred Shares ($500 million), and our 5.200% Series X Preferred Shares ($225 million). Redemption of such preferred shares will depend upon many factors, including the rate at which we could issue replacement preferred securities.

Medium and Long-Term Debt: We have increased our debt outstanding from $64 million at December 31, 2014 to $1.9 billion at December 31, 2019, and on January 24, 2020, we issued an additional €500 million ($551.6 million) of senior unsecured debt. Our $2.5 billion of debt outstanding at February 25, 2020 has an average interest rate of approximately 2.43%. While we have increased our use of debt as a capital source, and have broad powers to issue debt without a vote by our preferred or common shareholders, we expect to continue to remain conservatively capitalized and not subject ourselves to significant refinancing risk through effective “laddering” of our maturities.

Common equity: Except in connection with mergers, most notably a merger in 2006 with Shurgard Storage Centers, we have not raised capital through the issuance of common equity because lower cost alternatives have been available. However, we believe that the market for our common equity is liquid, with average trading volume in 2019 of approximately 885,000 common shares per day and, as a result, common equity is a significant potential source of capital.

Bridge financing: We have a $500.0 million revolving line of credit which we occasionally use as temporary “bridge” financing, along with short-term bank loans, until we are able to raise longer-term capital. As of

December 31, 2019, there were no borrowings outstanding on our revolving line of credit and no short-term bank loans.

Joint Venture Financing: We have participated in joint ventures with institutional investors in the past to acquire, develop, and operate self-storage facilities, most notably our joint venture to own Shurgard, prior to its Offering. Any future uses of joint venture financing will be based upon, among other considerations, the relative cost of joint venture financing as compared to other sources of capital. We do not have any current plans to utilize joint venture financing.

Sale of Properties: Generally, we have disposed of self-storage facilities only when compelled to do so through condemnation proceedings. Because we believe that we are an optimal operator of self-storage facilities, we have generally found that we cannot obtain sufficient value in selling properties because potential buyers cannot extract as much cash flow from the properties as we can. As a result, we do not presently expect to raise significant capital selling self-storage facilities; however, there can be no assurance that we will not.

Investments in Real Estate and Unconsolidated Real Estate Entities

Investment Policies and Practices with respect to our investments: Following are our investment practices and policies which, though we do not anticipate any significant alteration, can be changed by our board of trustees (the “Board”) without a shareholder vote:

Our investments primarily consist of direct ownership of self-storage facilities, as well as partial interests in entities we control that own self-storage facilities that we manage under the “Public Storage” brand name in the U.S. Our investments in self-storage facilities are described in more detail in Item 2, “Properties,” below.

We have an ownership interest in Shurgard, which owns storage facilities located in Europe under the “Shurgard” brand name.

Additional acquired interests in real estate will primarily include the acquisition of properties from third parties, as well as to a lesser extent, partial interests in entities in which we already have an interest.

To a lesser extent, we have interests in existing commercial properties (described in Item 2, “Properties”), containing commercial and industrial rental space, primarily through our investment in PSB.

Facilities Owned by Unconsolidated Real Estate Entities

At December 31, 2019, we had ownership interests in PSB and Shurgard (each discussed above), which we do not control or consolidate.

PSB and Shurgard’s debt has no recourse to us. See Note 4 to our December 31, 2019 financial statements for further disclosure regarding our investments in PSB and Shurgard. In addition, PSB’s public filings are available at its website, www.psbusinessparks.com and on the SEC website, and Shurgard’s public filings and publicly reported information can be obtained on its website, https://corporate.shurgard.eu and on the website of the Luxembourg Stock Exchange, http://www.bourse.lu.

Canadian self-storage facilities owned by Tamara Hughes Gustavson

At December 31, 2019, Tamara Hughes Gustavson, a member of our Board of Trustees, owned and controlled 63 self-storage facilities in Canada.  These facilities operate under the “Public Storage” tradename, which we license to the owners of these facilities for use in Canada on a royalty-free, non-exclusive basis. We have no ownership interest in these facilities and we do not own or operate any facilities in Canada.  If we chose to acquire or develop our own facilities in Canada, we would have to share the use of the “Public Storage” name in Canada. We have a

right of first refusal, subject to limitations, to acquire the stock or assets of the corporation engaged in the operation of these facilities if their owners agree to sell them. Our subsidiaries reinsure risks relating to loss of goods stored by customers in these facilities, and have received approximately $1.5 million, $1.3 million and $1.1 million for the years ended December 31, 2019, 2018 and 2017, respectively. Our right to continue receiving these premiums may be qualified.  

Limitations on Debt

Our revolving credit facility, U.S. Dollar Notes and Euro Notes contain various customary financial covenants, including limitations on our ability to encumber our properties with mortgages and limitations on the level of indebtedness. We believe we complied with each of these covenants as of December 31, 2019.

Employees

We had approximately 5,900 employees in the U.S. at December 31, 2019 who are engaged primarily in property operations.

Seasonality

We experience minor seasonal fluctuations in the demand for self-storage space, with demand and rental rates generally higher in the summer months than in the winter months. We believe that these fluctuations result in part from increased moving activity during the summer months.

Insurance

We carry property, earthquake, general liability, employee medical insurance and workers compensation coverage through internationally recognized insurance carriers, subject to deductibles. Our deductible for general liability is $2.0 million per occurrence. Our annual deductible for property loss is $25.0 million per occurrence. This deductible decreases to $5.0 million once we reach $35.0 million in aggregate losses for occurrences that exceed $5.0 million. Insurance carriers’ aggregate limits on these policies of $75.0 million for property losses and $102.0 million for general liability losses are higher than estimates of maximum probable losses that could occur from individual catastrophic events determined in recent engineering and actuarial studies; however, in case of multiple catastrophic events, these limits could be exceeded.

We reinsure a program that provides insurance to our customers from an independent third-party insurer. This program covers customer claims for losses to goods stored at our facilities as a result of specific named perils (earthquakes are not covered by this program), up to a maximum limit of $5,000 per storage unit. We reinsure all risks in this program, but purchase insurance to cover this exposure for a limit of $15.0 million for losses in excess of $5.0 million per occurrence. We are subject to licensing requirements and regulations in several states. Customers participate in the program at their option. At December 31, 2019, there were approximately 935,000 certificates held by our self-storage customers, representing aggregate coverage of approximately $3.2 billion.

Natural disasters or terrorist attacks could cause damage to our facilities, resulting in increased costs and reduced revenues. Natural disasters, such as earthquakes, fires, hurricanes and floods, or terrorist attacks could cause significant damage to our facilities and require significant repair costs, and make facilities temporarily uninhabitable, thereby reducing our revenues. Damage and business interruption losses could exceed the aggregate limits of our insurance coverage. In addition, because we self-insure a portion of our risks, losses below a certain level may not be covered by insurance. See Note 13 to our December 31, 2019 financial statements for a description of the risks of losses that are not covered by third-party insurance contracts. We may not have sufficient insurance coverage for losses caused by a terrorist attack, or such insurance may not be maintained, available or cost-effective. In addition, significant natural disasters, terrorist attacks, threats of future terrorist attacks, or resulting wider armed conflicts could have negative impacts on self-storage demand and/or our revenues.

Consequences of climate change, including severe weather events, and the steps taken to prevent climate change, could result in increased capital expenditures, increased expenses, and reduced revenues: Direct and indirect impacts of climate change, such as increased destructive weather events, fires, reduced lifespans and population reduction, reduced natural habitats, water, food, arable land, and other resources, as well as resulting armed conflicts, could increase our costs or reduce demand for our self-storage facilities. Governmental, political, and societal pressure could (i) require costly changes to future newly developed facilities, or require retrofitting of our existing facilities, to reduce carbon emissions through multiple avenues including changes to insulation, space configuration, lighting, heating, and air conditioning, (ii) increase energy costs as a result of switching to less carbon-intensive, but more expensive, sources of energy to operate our facilities, and (iii) result in consumers reducing their individual carbon footprints by owning fewer durable material consumer goods, collectibles, and other such items requiring storage, resulting in a reduced demand for our self-storage space.

Operating costs, including property taxes, could increase. We could be subject to increases in insurance premiums, property or other taxes, repair and maintenance costs, payroll, utility costs, workers compensation, and other operating expenses due to various factors such as inflation, labor shortages, commodity and energy price increases, weather, increases to minimum wage rates, changes to governmental safety and real estate use limitations, as well as other governmental actions. Our property tax expense, which totaled approximately $280.5 million during the year ended December 31, 2019, generally depends upon the assessed value of our real estate facilities as determined by assessors and government agencies, and accordingly could be subject to substantial increases if such agencies changed their valuation approaches or opinions or if new laws are enacted, especially if new approaches are adopted or laws are enacted that result in increased property tax assessments in states or geographies where we have a high concentration of facilities. See also “We have exposure to increased property tax in California” below.

The acquisition of existing properties or self-storage operating companies is subject to risks that may adversely affect our growth and financial results. We have acquired self-storage facilities from third parties in the past, and we expect to continue to do so in the future. We face significant competition for suitable acquisition properties from other real estate investors. As a result, we may be unable to acquire additional properties we desire or the purchase price for desirable properties may be significantly increased. Failures or unexpected circumstances in integrating facilities that we acquire directly or via the acquisition of operating companies into our operations, or circumstances we did not detect or anticipate during due diligence, such as environmental matters, needed repairs or deferred maintenance, customer collection issues, assumed liabilities, turnover of critical personnel involved in acquired operating companies, or the effects of increased property tax following reassessment of a newly-acquired property, as well as the general risks of real estate investment and mergers and acquisitions, could jeopardize realization of the anticipated earnings from an acquisition.

Development of self-storage facilities can subject us to risks.  At December 31, 2019, we have a pipeline of development projects totaling $619.2 million (subject to contingencies), and we expect to continue to seek additional development projects. There are significant risks involved in developing self-storage facilities, such as delays or cost increases due to changes in or failure to meet government or regulatory requirements, failure of revenue to meet our underwriting estimates, weather issues, unforeseen site conditions, or personnel problems. Self-storage space is generally not pre-leased, and rent-up of newly developed space can be delayed or ongoing cash flow yields can be reduced due to competition, reductions in storage demand, or other factors.

There is significant competition among self-storage operators and from other storage alternatives.  Our self-storage facilities generate most of our revenue and earnings. Competition in the local market areas in which many of our properties 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 will continue to do so as newly developed facilities are opened. Development of self-storage facilities by other operators could continue to increase, due to increases in availability of funds for investment or other reasons, and further intensify competition.

Our newly developed and expanded facilities, and facilities that we manage for third party owners, may negatively impact the revenues of our existing facilities. We continue to develop new self-storage facilities and expand our existing self-storage facilities. In addition, we are seeking to increase the number of self-storage facilities that we manage for third party owners in exchange for a fee, many of which are in the process of stabilization and are in proximity to our existing stabilized self-storage facilities. In order to hasten the fill-up of these new facilities, we aggressively price such space during the fill-up period. While we believe that this aggressive pricing allows us to increase our market share relative to our competitors and increase the cash flows of these properties, such pricing and the added capacity may also negatively impact our existing stabilized self-storage facilities that are in proximity to these unstabilized facilities.

Many of our existing self-storage facilities may be at a competitive disadvantage to newly developed facilities. There is a significant level of development of new self-storage facilities, by us and other operators. These newly developed facilities are generally of high quality, with a more fresh and vibrant appearance, more amenities such as climate control, more attractive office configurations, newer elements, and a more imposing and attractive retail presence as compared to many of our existing stabilized self-storage facilities, some of which were built as much as 50 years ago. Such qualitative differentials may negatively impact our ability to compete with these facilities for new tenants and our existing tenants may move to newly developed facilities.

We may incur significant liabilities from environmental contamination or moisture infiltration.   Existing or future laws impose or may impose liability on us to clean up environmental contamination on or around properties that we currently or previously owned or operated, even if we were not responsible for or aware of the environmental contamination or even if such environmental contamination occurred prior to our involvement with the property. We have conducted preliminary environmental assessments on most of our properties, which have not identified any material liabilities. These assessments, commonly referred to as “Phase 1 Environmental Assessments,” include an investigation (excluding soil or groundwater sampling or analysis) and a review of publicly available information regarding the site and other nearby properties.

We are also subject to potential liability relating to moisture infiltration, which can result in mold or other damage to our or our customers’ property, as well as potential health concerns. When we receive a complaint or otherwise become aware that an air quality concern exists, we implement corrective measures and seek to work proactively with our customers to resolve issues, subject to our contractual limitations on liability for such claims.

We are not aware of any environmental contamination or moisture infiltration related liabilities that could be material to our overall business, financial condition, or results of operation. However, we may not have detected all material liabilities, we could acquire properties with material undetected liabilities, or new conditions could arise or develop at our properties, any of which could result in a cash settlement or adversely affect our ability to sell, lease, operate, or encumber affected facilities.

Economic conditions can adversely affect our business, financial condition, growth and access to capital.

Our revenues and operating cash flow can be negatively impacted by reductions in employment and population levels, household and disposable income, and other general economic factors that lead to a reduction in demand for rental space in each of the markets in which we operate.

Our ability to raise capital to fund our activities may be adversely affected by challenging market conditions. In periods when the capital and credit markets experience significant volatility, the amounts, sources, and cost of

capital available to us may be adversely affected. If we were unable to raise capital at reasonable rates, prospective earnings growth through expanding our asset base could be limited.

We have exposure to European operations through our ownership in Shurgard.

We own approximately 35% of the common shares of Shurgard, and this investment has a $339.9 million book value and a $1.2 billion market value (based upon the closing trading price of Shurgard’s common stock) at December 31, 2019. We recognized $15.5 million in equity in earnings, and received $23.1 million in dividends, in 2019, with respect to Shurgard.

Shurgard, as an owner, operator, and developer of self-storage facilities, is subject to many of the same risks we are with respect to self-storage. However, through our investment in Shurgard, we are exposed to additional risks unique to the various European markets Shurgard operates in which may adversely impact our business and financial results, many of which are referred to in Shurgard’s public filings. These risks include the following:

Currency risks: Currency fluctuations can impact the fair value of our investment in Shurgard, our equity earnings, our ongoing dividends, and any other related repatriations of cash.

Legislative, tax, and regulatory risks: Shurgard is subject to a variety of local, national, and pan European laws and regulations related to permitting and land use, the environment, labor, and other areas, as well as income, property, sales, value added and employment tax laws. These laws can be difficult to apply or interpret and can vary in each country or locality, and are subject to unexpected changes in their form and application due to regional, national, or local political uncertainty and other factors. Such changes, or Shurgard’s failure to comply with these laws, could subject it to penalties or other sanctions, adverse changes in business processes, as well as potentially adverse income tax, property tax, or other tax burdens.

Impediments to capital repatriation could negatively impact the realization of our investment in Shurgard: Laws in Europe and the U.S. may create, impede, or increase our cost to repatriate distributions received from Shurgard or proceeds from the sale of Shurgard’s shares.

Risks of collective bargaining and intellectual property: Collective bargaining, which is prevalent in certain areas in Europe, could negatively impact Shurgard’s labor costs or operations. Many of Shurgard’s employees participate in various national unions.

Potential operating and individual country risks: Economic slowdowns or extraordinary political or social change in the countries in which it operates have posed, and could continue to pose, challenges or result in future reductions of Shurgard’s operating cash flows.

Liquidity of our ownership stake: We have no plans to liquidate our interest in Shurgard. However, while Shurgard is a publicly held entity, if we chose to, our ability to liquidate our shares in Shurgard in an efficient manner could be limited by the level of Shurgard’s public “float” relative to any ownership stake we sought to sell. Our existing relationship with our legacy joint venture partner may place further contractual limitations on our ability to sell all of the shares we own if we desired to do so.

Impediments of Shurgard’s public ownership structure: Shurgard’s strategic decisions, involving activities such as borrowing money, capital contributions, raising capital from third parties, as well as selling or acquiring significant assets, are determined by its board of directors. As a result, Shurgard may be precluded from taking advantage of opportunities that we would find attractive but that we may not be able to pursue economically separately, or it could take actions that we do not agree with.

We have exposure to commercial property risk through our ownership in PSB.

We own approximately 42% of the common equity of PSB, and this investment has a $427.9 million book value and a $2.4 billion market value (based upon the closing trading price of PSB’s common stock) at December 31, 2019. We recognized $54.1 million in equity in earnings, and received $60.7 million in dividends, in 2019, with respect to PSB.

PSB, as an owner, operator, and developer of real estate, is subject to many of the same risks we are with respect to real estate. However, we may be exposed to other risks as a result of PSB’s ownership specifically of commercial facilities. These risks are set forth in PSB’s Form 10-K for the year ended December 31, 2019, under “Item 1A. Risk Factors.”

The Hughes Family could significantly influence us and take actions adverse to other shareholders.  

At December 31, 2019, B. Wayne Hughes, our former Chairman and his family, which includes his daughter, Tamara Hughes Gustavson and his son, B. Wayne Hughes, Jr., who are both members of our Board of Trustees (collectively, the “Hughes Family”), owned approximately 14.1% of our aggregate outstanding common shares. Our declaration of trust permits the Hughes Family to own up to 35.66% of our outstanding common shares while it generally restricts the ownership by other persons and entities to 3% of our outstanding common shares unless our Board of Trustees grants an ownership waiver, as has occurred in certain cases for large mutual fund companies. Consequently, the Hughes Family may significantly influence matters submitted to a vote of our shareholders, including electing trustees, amending our organizational documents, dissolving and approving other extraordinary transactions, such as a takeover attempt, which may result in an outcome that may not be favorable to other shareholders.

Takeover attempts or changes in control could be thwarted, even if beneficial to shareholders.

In certain circumstances, shareholders might desire a change of control or acquisition of us, in order to realize a premium over the then-prevailing market price of our shares or for other reasons. However, the following could prevent, deter, or delay such a transaction:

Provisions of Maryland law may impose limitations that may make it more difficult for a third party to negotiate or effect a business combination transaction or control share acquisition with Public Storage. Currently, the Board has opted not to subject the Company to these provisions of Maryland law, but it could choose to do so in the future without shareholder approval.

To protect against the loss of our REIT status due to concentration of ownership levels, our declaration of trust generally limits the ability of a person, other than the Hughes Family or “designated investment entities” (each as defined in our declaration of trust), to own, actually or constructively, more than 3% of our outstanding common shares or 9.9% of the outstanding shares of any class or series of preferred or equity shares. Our Board may grant, and has previously granted, a specific exemption. These limits could discourage, delay or prevent a transaction involving a change in control of the Company not approved by our Board.

Similarly, current provisions of our declaration of trust and powers of our Board could have the same effect, including (1) limitations on removal of trustees, (2) restrictions on the acquisition of our shares of beneficial interest, (3) the power to issue additional common shares, preferred shares or equity shares on terms approved by the Board without obtaining shareholder approval, (4) the advance notice provisions of our bylaws and (5) the Board’s ability under Maryland law, without obtaining shareholder approval, to implement takeover defenses that we may not yet have and to take, or refrain from taking, other actions that could have the effect of delaying, deterring or preventing a transaction or a change in control.

If we failed to qualify as a REIT, we would have to pay substantial income taxes.

REITs are subject to a range of complex organizational and operational requirements. A qualifying REIT does not generally incur federal income tax on its net income that is distributed to its shareholders. Our REIT status is also dependent upon the ongoing REIT qualification of PSB as a result of our substantial ownership interest in it. We believe we have qualified as a REIT and we intend to continue to maintain our REIT status.

There can be no assurance that we qualify or will continue to qualify as a REIT, because of the highly technical nature of the REIT rules, the ongoing importance of factual determinations, the possibility of unidentified issues in prior periods, or changes in our circumstances, as well as share ownership limits in our articles of incorporation that do not necessarily ensure that our shareholder base is sufficiently diverse for us to qualify as a REIT. For any year we fail to qualify as a REIT, unless certain relief provisions apply (the granting of such relief could nonetheless result in significant excise or penalty taxes), we would not be allowed a deduction for dividends paid, we would be subject to corporate tax on our taxable income, and generally we would not be allowed to elect REIT status until the fifth year after such a disqualification. Any taxes, interest, and penalties incurred would reduce our cash available for distributions to shareholders and could negatively affect our stock price. However, for years in which we failed to qualify as a REIT, we would not be subject to REIT rules that require us to distribute substantially all of our taxable income to our shareholders.

Holders of our preferred shares have dividend, liquidation and other rights that are senior to the rights of the holders of shares of our common stock.

Holders of our preferred shares are entitled to cumulative dividends before any dividends may be declared or set aside on our common stock. Upon liquidation, holders of our preferred shares will receive a liquidation preference of $25,000 per share (or $25.00 per depositary share) plus any accrued and unpaid distributions before any payment is made to the common shareholders. These preferences may limit the amount received by our common shareholders either from ongoing distributions or upon liquidation. In addition, our preferred shareholders have the right to elect two additional directors to our Board whenever dividends are in arrears in an aggregate amount equivalent to six or more quarterly dividends, whether or not consecutive.

We are increasingly dependent upon Google to source our customers.

Approximately 59% of our new storage customers in 2019 were sourced directly or indirectly through “unpaid” search and “paid” search campaigns on Google. We believe that the vast majority of customers searching for self-storage use Google at some stage in their shopping experience. Google is providing tools to allow smaller and less sophisticated operators to bid for search terms, increasing competition for self-storage search terms. The predominance of Google in the shopping experience, as well as Google’s enabling of additional competitors to bid for placements in self-storage search terms, may reduce the number of new customers that we can procure, and/or increase our costs to obtain new customers.

Preferred Shareholders are subject to certain risks.

Holders of our preferred shares have preference rights over our common shareholders with respect to liquidation and distributions, which give them some assurance of continued payment of their stated dividend rate, and receipt of their principal upon liquidation of the Company or redemption of their securities. However, holders of our Preferred Shares should consider the following risks:

The Company has in the past, and could in the future, issue or assume additional debt. Preferred shareholders would be subordinated to the interest and principal payments of such debt, which would increase the risk that there would not be sufficient funds to pay distributions or liquidation amounts to the preferred shareholders.

The Company has in the past, and could in the future, issue additional preferred shares that, while pari passu to the existing preferred shares, increases the risk that there would not be sufficient funds to pay distributions to the preferred shareholders.

While the Company has no plans to do so, if the Company were to lose its REIT status or no longer elect REIT status, it would no longer be required to distribute its taxable income to maintain REIT status. If, in such a circumstance, the Company ceased paying dividends, unpaid distributions to the preferred shareholders would continue to accumulate. The preferred shareholders would have the ability to elect two additional members to serve on our Board of Trustees until the arrearage was cured. The preferred shareholders would not receive any compensation (such as interest) for the delay in the receipt of distributions, and it is possible that the arrearage could accumulate indefinitely.

Changes in tax laws could negatively impact us.

The United States Treasury Department and Congress frequently review federal income tax legislation, regulations and other guidance. We cannot predict whether, when, or to what extent new federal tax laws, regulations, interpretations or rulings will be adopted. Any legislative action may prospectively or retroactively modify our tax treatment and, therefore, may adversely affect taxation of us or our shareholders.

Changes made by the Tax Cuts and Jobs Act (the “TCJA”), signed into law on December 22, 2017, limit our ability to deduct compensation in excess of $1 million paid to certain senior executives. This could require us to increase distributions to our shareholders in the future in order to avoid paying tax and to maintain our REIT status.

We may pay some taxes, reducing cash available for shareholders.

Even if we qualify as a REIT for federal income tax purposes, we may be subject to some federal, foreign, state and local taxes on our income and property. Since January 1, 2001, certain consolidated corporate subsidiaries of the Company have elected to be treated as “taxable REIT subsidiaries” for federal income tax purposes, and are taxable as regular corporations and subject to certain limitations on intercompany transactions. If tax authorities determine that amounts paid by our taxable REIT subsidiaries to us are not reasonable compared to similar arrangements among unrelated parties, we could be subject to a 100% penalty tax on the excess payments, and ongoing intercompany arrangements could have to change, resulting in higher ongoing tax payments. To the extent the Company is required to pay federal, foreign, state or local taxes or federal penalty taxes due to existing laws or changes thereto, we will have less cash available for distribution to shareholders.

In addition, certain local and state governments have imposed taxes on self-storage rent. While in most cases those taxes are paid by our customers, they increase the cost of self-storage rental to our customers and can negatively impact our revenues. Other local and state governments may impose self-storage rent taxes in the future.

We have exposure to increased property tax in California.

Approximately $580 million of our 2019 net operating income is from our properties in California, and we incurred approximately $42 million in related property tax expense. Due to the impact of Proposition 13, which generally limits increases in assessed values to 2% per year, the assessed value and resulting property tax we pay is less than it would be if the properties were assessed at current values. From time to time, proposals have been made to reduce the beneficial impact of Proposition 13, particularly with respect to commercial and industrial (non-residential) real estate, which would include self-storage facilities. In late 2018, an initiative qualified for California’s November 2020 statewide ballot that would create a “split roll,” generally making Proposition 13’s protections only applicable to residential real estate. The sponsors of the original initiative are attempting to qualify a revised proposal that has a similar impact in terms of property taxes, but may have a higher change of passage. If the revised initiative is qualified, it will replace the first initiative on the November 2020 ballot. If the original or replacement initiative were to be adopted, it would end the beneficial effect of Proposition 13 for our properties, and our property tax expense could increase substantially, adversely affecting our cash flow from operations and net income.

We cannot predict whether (i) the revised initiative will qualify to replace the first qualified initiative, (ii) the initiative that ends up on the November 2020 ballot will pass or (iii) other changes to Proposition 13 may be proposed or adopted in the future.

We are exposed to ongoing litigation and other legal and regulatory actions, which may divert management’s time and attention, require us to pay damages and expenses or restrict the operation of our business.

We have over 5,900 employees, more than 1.4 million customers, and we conduct business at facilities with 169 million net rentable square feet of storage space. As a result, we are subject to the risk of legal claims and proceedings (including class actions) and regulatory enforcement actions in the ordinary course of our business and otherwise, and we could incur significant liabilities and substantial legal fees as a result of these actions. Resolution of these claims and actions may divert time and attention by our management could involve payment of damages or expenses by us, all of which may be significant, and could damage our reputation and our brand. In addition, any such resolution could involve our agreement to terms that restrict the operation of our business. The results of legal proceedings cannot be predicted with certainty. We cannot guarantee losses incurred in connection with any current or future legal or regulatory proceedings or actions will not exceed any provisions we may have set aside in respect of such proceedings or actions or will not exceed any available insurance coverage. The impact of any such legal claims, proceedings, and regulatory enforcement actions and could negatively impact our operating results, cash flow available for distribution or reinvestment, and/or the price of our common shares.

In addition, through exercising their authority to regulate our activities, governmental agencies can otherwise negatively impact our business by increasing costs or decreasing revenues.

We are heavily dependent on computer systems, telecommunications and the Internet to process transactions, make payments, summarize results and manage our business. The failure or disruption of our computer and communications systems could significantly harm our business.

We are heavily dependent upon automated information technology and Internet commerce, with more than half of our new customers coming from the telephone or over the Internet. We centrally manage significant components of our operations with our computer systems, including our financial information, and we also rely extensively on third-party vendors to retain data, process transactions and provide other systems services. These systems are subject to damage or interruption from power outages, computer and telecommunications failures, hackers, computer worms, viruses and other destructive or disruptive security breaches and catastrophic events. Such incidents could also result in significant costs to repair or replace such networks or information systems, as well as actual monetary losses in case of a breach that resulted in fraudulent payments or other cash transactions. As a result, our operations could be severely impacted by a natural disaster, terrorist attack, attack by hackers, acts of vandalism, data theft, misplaced or lost data, programming or human error, or other circumstance that results in a significant outage of our systems or those of our third party providers, despite our use of back up and redundancy measures.

If our confidential information is compromised or corrupted, including as a result of a cybersecurity breach, our reputation and business relationships could be damaged, which could adversely affect our financial condition and operating results.

In the ordinary course of our business we acquire and store sensitive data, including personally identifiable information of our prospective and current customers and our employees. The secure processing and maintenance of this information is critical to our operations and business strategy. Although we believe we have taken commercially reasonable steps to protect the security of our confidential information, information security risks have generally increased in recent years due to the rise in new technologies and the increased sophistication and activities of perpetrators of cyberattacks. Despite our security measures, we have experienced security breaches due to cyberattacks and additional breaches could occur in the future. In these cases, our information technology and infrastructure could be vulnerable and our or our customers’ or employees’ confidential information could be compromised or misappropriated. Any such breach could result in serious and harmful consequences for us or our tenants.

Our confidential information may also be compromised due to programming or human error or malfeasance.

We must continually evaluate and adapt our systems and processes to address the evolving threat landscape, and therefore there is no guarantee that they will be adequate to safeguard against all data security breaches or misuses of data. In addition, as the regulatory environment related to information security, data collection and use, and privacy becomes increasingly rigorous, with new and changing requirements applicable to our business from multiple regulatory agencies at the local, state, federal, or international level, compliance with those requirement could also result in additional costs, or we could fail to comply with those requirements due to various reasons such as not being aware of them.

Any such access, disclosure or other loss of information could result in legal claims or proceedings, liability under laws that protect the privacy of personal information, regulatory penalties, disruption to our operations and the services we provide to customers or damage our reputation, any of which could adversely affect our results of operations, reputation and competitive position. In addition, our customers could lose confidence in our ability to protect their personal information, which could cause them to discontinue leasing our self-storage facilities. Such events could lead to lost future revenues and adversely affect our results of operations and could result in remedial and other costs, fines or lawsuits, which could be in excess of any available insurance that we have procured.

We are subject to California’s new privacy law which will require us to incur compliance costs and may subject us to litigation that may affect our operating results and financial condition.

The California Consumer Privacy Act (the “CCPA”) went into effect on January 1, 2020. The CCPA requires, among other things, companies that collect personal information about California residents to make new disclosures to those residents about their data collection, use and sharing practices, allows residents to opt out of certain data sharing with third parties, and provides a new cause of action for data breaches. However, regulations from the California Attorney General have not been finalized, and it is expected that additional amendments to the CCPA will be introduced in 2020. It therefore remains unclear what, if any, modifications will be made to the CCPA or how it will be interpreted. While we believe we have developed processes to comply with CCPA requirements, a regulatory agency may not agree with certain of our implementation decisions, which could subject us to litigation, regulatory actions or changes to our business practices that could increase costs or reduce revenues. Other states have also considered or are considering privacy laws similar to the CCPA. Similar laws may be implemented in other jurisdictions that we do business in and in ways that may be more restrictive than the CCPA, increasing the cost of compliance, as well as the risk of noncompliance, on our business.

Our tenant reinsurance business is subject to governmental regulation which could reduce our profitability or limit our growth.

We hold Limited Lines Self-Service Storage Insurance Agent licenses from a number of individual state departments of insurance and are subject to state governmental regulation and supervision.  Our continued ability to maintain these Limited Lines Self-Service Storage Insurance Agent licenses in the jurisdictions in which we are licensed depends on our compliance with related rules and regulations.  The regulatory authorities in each jurisdiction 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 agents. 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 reduce our net income.
