MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS

For purposes of the following discussion, references to “the Company,” “we” and “us” mean Public Storage and not its subsidiaries or affiliates. The following discussion describes the material U.S. federal income tax considerations relating to the taxation of Public Storage as a REIT and the acquisition, ownership and disposition of our common shares. If we offer debt securities, or equity securities other than common shares, information about additional U.S. federal income tax considerations with respect to those securities will be included in the documents pursuant to which those securities are offered.

Because this is a summary that is intended to address only the U.S. federal income tax considerations relating to the ownership and disposition of our common shares, it may not contain all the information that may be important in your specific circumstances. As you review this discussion, you should keep in mind that:

41

You are urged both to review the following discussion and to consult with your tax advisor to determine the effect of acquiring, owning and disposing of our common shares in your individual tax situation, including any state, local or non-U.S. tax consequences.

The information in this section is based on the Code, current, temporary and proposed regulations promulgated by the U.S. Treasury Department, the legislative history of the Code, current administrative interpretations and practices of the IRS, and court decisions. The reference to IRS interpretations and practices includes IRS practices and policies as endorsed in private letter rulings, which are not binding on the IRS except with respect to the taxpayer that receives the ruling. In each case, these sources are relied upon as they exist on the date of this registration statement. Future legislation, regulations, administrative interpretations and court decisions could change current law or adversely affect existing interpretations of current law. Any change could apply retroactively. Except as described under “—Taxation of Public Storage as a REIT—Income Tests Applicable to REITs,” we have not obtained any rulings from the IRS concerning the tax treatment of the matters discussed below. Accordingly, even if there is no change in the applicable law, no assurance can be provided that the statements made in the following discussion, which do not bind the IRS or the courts, will not be challenged by the IRS or will be sustained by a court if so challenged.

Taxation of Public Storage as a REIT

General. We elected to be taxed as a REIT under the Code beginning with our taxable year ended December 31, 1981. A REIT generally is not subject to U.S. federal income tax on the net income that it distributes to shareholders if it meets the applicable REIT distribution requirements and other requirements for REIT qualification under the Code.

We believe that we have been and that we are organized and have operated, and we intend to continue to operate, to qualify as a REIT, but there can be no assurance that we qualify or will remain qualified as a REIT. Qualification and taxation as a REIT depend upon our ability to meet, through actual annual (or in some cases quarterly) operating results, requirements relating to income, asset ownership, distribution levels and diversity of share ownership, and the various other REIT qualification requirements imposed under the Code. Given the complex nature of the REIT qualification requirements, the ongoing importance of factual determinations and the possibility of future changes in our circumstances, we cannot provide any assurance that our actual operating results will satisfy the requirements for taxation as a REIT under the Code for any particular taxable year.

The sections of the Code that relate to our qualification and operation as a REIT are highly technical and complex. This discussion sets forth material aspects of the sections of the Code that govern the U.S. federal income tax treatment of a REIT and its shareholders. This summary is qualified in its entirety by the applicable Code provisions, relevant rules and Treasury regulations, and related administrative and judicial interpretations.

Taxation. For each taxable year in which we qualify for taxation as a REIT, we generally will not be subject to U.S. federal corporate income tax on our “REIT taxable income” (generally, taxable income of the REIT subject to specified adjustments, including a deduction for dividends paid) that is distributed currently to our shareholders. This treatment substantially eliminates the “double taxation” at the corporate and shareholder levels that generally results from an investment in a non-REIT C corporation. A non-REIT C corporation is a corporation that generally is required to pay tax at the corporate level. Double taxation means taxation once at the corporate level when income is earned and once again at the shareholder level when the income is distributed. In general, the income that we generate is taxed only at the shareholder level upon a distribution of dividends to our shareholders.

U.S. shareholders generally will be subject to taxation on dividends distributed by us (other than designated capital gain dividends and “qualified dividend income”) at rates applicable to ordinary income, instead of at lower capital gain rates. For taxable years beginning before January 1, 2026, generally, U.S. shareholders that are individuals, trusts or estates may deduct 20% of the aggregate amount of ordinary dividends distributed by us,

42

subject to certain limitations. Capital gain dividends and qualified dividend income will continue to be subject to a maximum 20% rate.

While we generally will not be subject to corporate income taxes on income that we distribute currently to shareholders, we will be subject to U.S. federal income tax as follows:

43

Furthermore, notwithstanding our status as a REIT, we also may have to pay certain state and local income taxes, because not all states and localities treat REITs the same as they are treated for U.S. federal income tax purposes. Moreover, each of our taxable REIT subsidiaries (as further described below) is subject to U.S. federal, state and local corporate income taxes on its net income.

If we are subject to taxation on our REIT taxable income or subject to tax due to the sale of a built-in gain asset that was acquired in a carry-over basis from a non-REIT C Corporation, some of the dividends we pay to our shareholders during the following year may be subject to tax at the reduced capital gains rates, rather than taxed at ordinary income rates. See “—Taxation of U.S. Shareholders—Qualified Dividend Income.”

Requirements for Qualification as a REIT. The Code defines a REIT as a corporation, trust or association:

44

The Code provides that conditions (1), (2), (3) and (4) above must be met during the entire taxable year and condition (5) above must be met during at least 335 days of a taxable year of 12 months, or during a proportionate part of a taxable year of less than 12 months. Conditions (5) and (6) do not apply until after the first taxable year for which an election is made to be taxed as a REIT. Condition (6) must be met during the last half of each taxable year. For purposes of determining share ownership under condition (6) above, a supplemental unemployment compensation benefits plan, a private foundation or a portion of a trust permanently set aside or used exclusively for charitable purposes generally is considered an individual. However, a trust that is a qualified trust under Section 401(a) of the Code generally is not considered an individual, and beneficiaries of a qualified trust are treated as holding shares of a REIT in proportion to their actuarial interests in the trust for purposes of condition (6) above.

We believe that we have been organized, have operated and have issued sufficient shares of beneficial ownership with sufficient diversity of ownership to allow us to satisfy the above conditions. In addition, our organizational documents contain restrictions regarding the transfer of our shares that are intended to assist us in continuing to satisfy the share ownership requirements described in conditions (5) and (6) above. The ownership restrictions in our declaration of trust generally prohibit the actual or constructive ownership of more than 3% of our outstanding common shares or more than 9.9% of the outstanding class or series of preferred or equity shares, in each case, other than certain “excepted holders” or “designated investment entities,” (each as defined in our declaration of trust), which are subject to separate limits set forth in our declaration of trust, unless an exception is established by the board of trustees. See “Description of Common Shares—Ownership Limitations.”

The REIT protective provisions of our organizational documents are modeled after certain arrangements that the IRS has ruled in private letter rulings will preclude a REIT from being considered to violate the ownership restrictions so long as the arrangements are enforceable as a matter of state law and the REIT seeks to enforce them as and when necessary. There can be no assurance, however, that the IRS might not seek to take a different position concerning Public Storage (a private letter ruling is legally binding only as to the taxpayer to whom it was issued and we will not seek a private ruling on this issue) or contend that we failed to enforce these various arrangements. Accordingly, there can be no assurance that these arrangements necessarily will preserve our REIT status. If we fail to satisfy these share ownership requirements, we will fail to qualify as a REIT.

To monitor compliance with condition (6) above, a REIT is required to send annual letters to its shareholders requesting information regarding the actual ownership of its shares. If we comply with the annual letters requirement and do not know, or exercising reasonable diligence, would not have known, of a failure to meet condition (6) above, then we will be treated as having met condition (6) above.

To qualify as a REIT, we cannot have at the end of any taxable year any undistributed earnings and profits that are attributable to a non-REIT taxable year. As a result of mergers we have entered into, Public Storage has succeeded to various tax attributes of those entities and their predecessors, including any undistributed earnings and profits. We do not believe that we have acquired any undistributed non-REIT earnings and profits and we believe that the REITs with which we have merged qualified as REITs at the time of acquisition. However, neither these entities nor Public Storage has sought an opinion of counsel or outside accountants to the effect that we did not acquire any undistributed non-REIT earnings and profits. There can be no assurance that the IRS would not contend otherwise on a subsequent audit. If it was determined that we had at the end of any taxable year any undistributed earnings and profits that are attributable to a non-REIT taxable year, and we were unable to take advantage of applicable “deficiency dividend” procedures, we could fail to qualify as a REIT. Moreover, if we were considered to be a “successor” under the applicable Treasury regulations to a corporation that had failed to qualify as a REIT at the time of its merger with Public Storage, we could fail to qualify as a REIT.

Qualified REIT Subsidiaries. We may acquire 100% of the stock of one or more corporations that are qualified REIT subsidiaries. A corporation will qualify as a qualified REIT subsidiary if we own 100% of its stock and it is not a taxable REIT subsidiary. A qualified REIT subsidiary will not be treated as a separate corporation, and all assets, liabilities and items of income, deduction and credit of a qualified REIT subsidiary

45

will be treated as our assets, liabilities and such items (as the case may be) for all purposes of the Code, including the REIT qualification tests. For this reason, references in this discussion to our income and assets should be understood to include the income and assets of any qualified REIT subsidiary we own. A qualified REIT subsidiary will not be subject to U.S. federal income tax, although it may be subject to state and local taxation in some states. Our ownership of the voting stock of a qualified REIT subsidiary will not violate the asset test restrictions against ownership of securities of any one issuer which constitute more than 10% of the voting power or value of such issuer’s securities or more than five percent of the value of our total assets, as described below in “—Asset Tests Applicable to REITs.”

Taxable REIT Subsidiaries. A taxable REIT subsidiary is a corporation other than a REIT in which we directly or indirectly hold stock, which has made a joint election with us to be treated as a taxable REIT subsidiary under Section 856(l) of the Code. A taxable REIT subsidiary also includes any corporation other than a REIT in which a taxable REIT subsidiary of ours owns, directly or indirectly, securities, (other than certain “straight debt” securities), which represent more than 35% of the total voting power or value of the outstanding securities of such corporation. Other than some activities relating to lodging and health care facilities, a taxable REIT subsidiary may generally engage in any business, including the provision of customary or non-customary services to our tenants without causing us to receive impermissible tenant service income under the REIT gross income tests. A taxable REIT subsidiary is required to pay regular U.S. federal income tax, and state and local income tax where applicable, as a non-REIT C corporation. If dividends are paid to us by our taxable REIT subsidiary, then a portion of the dividends we distribute to shareholders who are taxed at individual rates will generally be eligible for taxation at lower capital gains rates, rather than at ordinary income rates. See “Taxation of U.S. Shareholders—Qualified Dividend Income.”

Generally, a taxable REIT subsidiary can perform impermissible tenant services without causing us to receive impermissible tenant services income under the REIT income tests. However, several provisions applicable to the arrangements between a REIT and its taxable REIT subsidiaries are intended to ensure that a taxable REIT subsidiary will be subject to an appropriate level of U.S. federal income taxation. For example, a taxable REIT subsidiary is limited in its ability to deduct interest payments made directly or indirectly to us in excess of a certain amount. See “—Interest Deduction Limitation.” In addition, a REIT will be obligated to pay a 100% penalty tax on some payments that it receives or on certain expenses deducted by the taxable REIT subsidiary, and, commencing with our taxable year that began on January 1, 2016, on income earned by our taxable REIT subsidiaries for services provided to, or on behalf of, us (and not to services provided to tenants), if the economic arrangements between the REIT, the REIT’s tenants and the taxable REIT subsidiary are not comparable to similar arrangements among unrelated parties. Our taxable REIT subsidiaries may make interest and other payments to us and to third parties in connection with activities related to our properties. There can be no assurance that the IRS might not seek to impose the 100% excise tax on a portion of payments received by us from, or expenses deducted by, or service income imputed to, our taxable REIT subsidiaries.

One or more of our subsidiaries have elected, together with us, to be treated as taxable REIT subsidiaries of Public Storage. These entities have engaged in businesses such as providing moving services and tenant reinsurance, and selling locks, boxes and packing materials, among other activities.

Ownership of Partnership Interests by a REIT. A REIT that owns an equity interest in an entity treated as a partnership for U.S. federal income tax purposes is deemed to own its share (based upon its proportionate share of the capital of the partnership) of the assets of the partnership and is deemed to earn its proportionate share of the partnership’s income. However, solely for purposes of the 10% value test described below, the determination of a REIT’s interest in the partnership’s assets is based on the REIT’s proportionate interest in the equity and certain debt securities issued by the partnership. The assets and gross income of the partnership retain the same character in the hands of the REIT for purposes of the gross income and asset tests applicable to REITs as described below. We have acquired interests in various partnerships that own and operate properties. Thus, our proportionate share of the assets and items of income of PS Business Parks, L.P. or other partnerships, including any such partnerships’ shares of assets and items of income of any subsidiaries that are partnerships or limited

46

liability companies treated as partnerships for U.S. federal income tax purposes, are treated as assets and items of income of Public Storage for purposes of applying the REIT asset and income tests. For these purposes, under current Treasury regulations our interests in each of the partnerships must be determined in accordance with our “capital interest” in each entity, as applicable.

We believe that PS Business Parks, L.P. and each of the partnerships and limited liability companies in which we own an interest, directly or through another partnership or limited liability company, will be treated as partnerships or disregarded for U.S. federal income tax purposes and will not be taxable as corporations. If any of these entities were treated as a corporation, it would be subject to an entity level tax on its income and we could fail to meet the REIT income and asset tests. See “—Income Tests Applicable to REITs” and “—Asset Tests Applicable to REITs” below.

Effective for tax years beginning on or after January 1, 2018, under the Bipartisan Budget Act of 2015, liability is imposed on a partnership (rather than its partners) for adjustments to reported partnership taxable income resulting from audits or other tax proceedings. The liability can include an imputed underpayment of tax, calculated by using the highest marginal U.S. federal income tax rate, as well as interest and penalties on such imputed underpayment of tax. Using certain rules, partnerships may be able to transfer these liabilities to their partners, but our partnerships may not qualify for those rules and the relevant partnership agreements may not authorize those transfers.

Income Tests Applicable to REITs. To qualify as a REIT, we must satisfy two gross income tests which are applied on an annual basis. First, in each taxable year we must derive directly or indirectly at least 75% of our gross income, excluding gross income from prohibited transactions, from investments relating to real property or mortgages on real property or from some types of temporary investments. Income from investments relating to real property or mortgages on related property includes “rents from real property,” gains on the disposition of real estate, dividends paid by another REIT and interest on obligations secured by mortgages on real property or on interests in real property. Second, in each taxable year we must derive at least 95% of our gross income, excluding gross income from prohibited transactions, from any combination of income qualifying under the 75% test and dividends, interest, and gain from the sale or disposition of stock or securities. Commencing with our taxable year that began on January 1, 2016, interest income and gain from the sale of a debt instrument issued by a “publicly offered REIT,” unless the debt instrument is secured by real property or an interest in real property, is not treated as qualifying income for purposes of the 75% gross income test but will continue to be treated as qualifying income for purposes of the 95% gross income test. A “publicly offered REIT” means a REIT that is required to file annual and periodic reports with the SEC under the Exchange Act.

Rents we receive will qualify as “rents from real property” for the purpose of satisfying the gross income requirements for a REIT described above only if several conditions are met:

47

In light of these requirements, we do not intend to take any of the actions listed below, unless we determine that the resulting nonqualifying income, taken together with all other nonqualifying income that we earn in the taxable year, will not jeopardize our status as a REIT:

The ownership of certain partnership interests creates several issues regarding our satisfaction of the gross income tests. First, we earn property management fees from these partnerships. Existing Treasury regulations do not address the treatment of management fees derived by a REIT from a partnership in which the REIT holds a partnership interest, but the IRS has issued a number of private letter rulings holding that the portion of the management fee that corresponds to the REIT’s capital interest in the partnership in effect is disregarded in applying the gross income tests when the REIT holds a “substantial” interest in the partnership. We disregard the portion of management fees derived from partnerships in which we are a partner that corresponds to our interest in these partnerships in determining the amount of our nonqualifying income. Private letter rulings, while indicative of the IRS’s views as to a particular issue, cannot be relied upon by a taxpayer other than the taxpayer to whom the ruling has been issued. There can be no assurance, therefore, that the IRS would not take a contrary position with respect to Public Storage, either rejecting the approach set forth in the private letter rulings mentioned above or contending that our situation is distinguishable from those addressed in the private letter rulings (for example, arguing that we do not have a “substantial” interest in the partnerships).

In addition, we acquired interests in certain of these partnerships that entitle us to a percentage of profits (either from operations, or upon a sale, or both) in excess of the percentage of total capital originally contributed to the partnership with respect to such interest. Existing Treasury regulations do not specifically address how our “capital interest” in partnerships of this type should be determined. This determination is relevant because it

48

affects both the percentage of the gross rental income of the partnership that is considered gross rental income (or qualifying income) to us and the percentage of the management fees paid to us that is disregarded in determining our nonqualifying income. In determining our “capital interest” in the various partnerships, we estimate the percentage of the partnership’s assets that would be distributed to us if those assets were sold and distributed among the partners in accordance with the applicable provisions of the partnership agreements. There can be no assurance, however, that the IRS will agree with this methodology and not contend that another, perhaps less favorable, method must be used for purposes of determining our “capital interests,” which could adversely affect our ability to satisfy the 75% and 95% gross income tests. Moreover, in connection with the Shurgard Self Storage SA merger, we have acquired indirect equity interests in real estate located outside of the United States, and Public Storage may acquire additional interests in non-U.S. properties both directly and through equity interests in partnerships, joint ventures, or other legal entities that have invested in real estate. These investments carry risks and uncertainties with respect to our status as a REIT that are not present when we invest directly in real estate in the U.S. and against which we may not be able to protect. For purposes of the 75% and 95% gross income tests, certain foreign currency income and gains recognized after July 30, 2008 are disregarded for purposes of determining gross income.

“Interest” income that depends in whole or in part on the income or profits of any person generally will be non-qualifying income for purposes of the 75% or 95% gross income tests. However, interest based on a fixed percentage or percentages of gross receipts or sales may still qualify under the gross income tests. We do not expect to derive significant amounts of interest that would fail to qualify under both the 75% and 95% gross income tests.

Our share of any dividends received from our corporate subsidiaries that are not “qualified REIT subsidiaries” (and from other corporations in which we own an interest) will qualify for purposes of the 95% gross income test but not for purposes of the 75% gross income test. We do not anticipate that we will receive sufficient dividends to cause us to exceed the limit on nonqualifying income under the 75% gross income test. Dividends that we receive from other qualifying REITs will qualify for purposes of both REIT income tests.

If we fail to satisfy one or both of the 75% or 95% gross income tests for any taxable year, we may nevertheless qualify as a REIT for that year if we are entitled to relief under the Code. These relief provisions generally will be available if our failure to meet the tests is due to reasonable cause and not due to willful neglect, and we disclose to the IRS the sources of our income as required by the Code and applicable regulations. It is not possible, however, to state whether in all circumstances we would be entitled to the benefit of these relief provisions. For example, if we fail to satisfy the gross income tests because nonqualifying income that we intentionally incur exceeds the limits on nonqualifying income, the IRS could conclude that the failure to satisfy the tests was not due to reasonable cause. If these relief provisions are inapplicable to a particular set of circumstances, we will fail to qualify as a REIT. As discussed under “—Taxation of Public Storage as a REIT—General” even if these relief provisions apply, a tax would be imposed based on the amount of nonqualifying income.

Prohibited Transaction Income. Any gain that we realize on the sale of any property held as inventory or otherwise held primarily for sale to customers in the ordinary course of business, including our share of any such gain realized through our subsidiary partnerships and disregarded entities for U.S. federal income tax purposes, will be treated as income from a prohibited transaction that is subject to a 100% penalty tax. Under existing law, whether property is held as inventory or primarily for sale to customers in the ordinary course of a trade or business is a question of fact that depends on all the facts and circumstances surrounding the particular transaction. However, we will not be treated as a dealer in real property for the purpose of the 100% penalty tax if: (i) we have held the property for at least two years for the production of rental income prior to the sale, (ii) capitalized expenditures on the property in the two years preceding the sale are less than 30% of the net selling price of the property, and (iii) we either (a) have seven or fewer sales of property (excluding certain property obtained through foreclosure) for the year of sale or (b) the aggregate tax basis of property sold during the year is 10% or less of the aggregate tax basis of all of our assets as of the beginning of the taxable year,

49

(c) the fair market value of property sold during the year is 10% or less of the aggregate fair market value of all of our assets as of the beginning of the taxable year; or (d) the aggregate adjusted basis of property sold during the year is 20% or less of the aggregate adjusted basis of all of our assets as of the beginning of the taxable year and the aggregate adjusted basis of property sold during the 3-year period ending with the year of sale is 10% or less of the aggregate tax basis of all of our assets as of the beginning of each of the three taxable years ending with the year of sale; or (e) the fair market value of property sold during the year is 20% or less of the aggregate fair market value of all of our assets as of the beginning of the taxable year and the fair market value of property sold during the 3-year period ending with the year of sale is 10% or less of the aggregate fair market value of all of our assets as of the beginning of each of the three taxable years ending with the year of sale. If we rely on clauses (b), (c), (d), or (e) in the preceding sentence, substantially all of the marketing and development expenditures with respect to the property sold must be made through an independent contractor from whom we derive no income or our taxable REIT subsidiary. The sale of more than one property to one buyer as part of one transaction constitutes one sale for purposes of this “safe harbor.”

Penalty Tax. Any redetermined rents, redetermined deductions or excess interest we generate will be subject to a 100% penalty tax. The items subject to the 100% penalty tax also include “redetermined taxable REIT subsidiary service income.” Redetermined taxable REIT subsidiary service income is gross income (less deductions allocable thereto) of a taxable REIT subsidiary attributable to services provided to, or on behalf of (and not to services provided to tenants), us that is less than the amounts that would have been paid by us to the taxable REIT subsidiary if based on arm’s-length negotiations. In general, redetermined rents are rents from real property that are overstated as a result of services furnished by one of our taxable REIT subsidiaries to any of our tenants, and redetermined deductions and excess interest represent amounts that are deducted by a taxable REIT subsidiary for payments to us that are in excess of the amounts that would have been deducted based on arm’s-length negotiations. Rents we receive will not constitute redetermined rents if they qualify for the safe harbor provisions contained in the Code. Safe harbor provisions are provided where:

While we anticipate that any fees paid to a taxable REIT subsidiary for tenant services will reflect arm’s-length rates, a taxable REIT subsidiary may under certain circumstances provide tenant services which do not satisfy any of the safe-harbor provisions described above. Until regulations are issued to carry out the purposes of the penalty tax provisions, a REIT and its taxable REIT subsidiaries may base their intercompany allocations on any reasonable method. Nevertheless, these determinations are inherently factual, and the IRS has broad discretion to assert that amounts paid between related parties should be reallocated to clearly reflect their respective incomes. If the IRS successfully made such an assertion, we would be required to pay a 100% penalty tax on the redetermined rent, redetermined deductions or excess interest, as applicable.

Asset Tests Applicable to REITs. At the close of each quarter of our taxable year, we must satisfy certain tests relating to the nature and diversification of our assets:

50

Securities for purposes of the asset tests may include debt securities. However, the Code specifically provides that the following types of debt will not be taken into account for purposes of the 10% value test: (1) securities that meet the “straight debt” safe-harbor, as discussed in the next paragraph; (2) loans to individuals or estates; (3) obligations to pay rent from real property; (4) rental agreements described in Section 467 of the Code; (5) any security issued by other REITs; (6) certain securities issued by a state, the District of Columbia, a foreign government, or a political subdivision of any of the foregoing, or the Commonwealth of Puerto Rico; and (7) any other arrangement as determined by the IRS. In addition, for purposes of the 10% value test only, to the extent we hold debt securities that are not described in the preceding sentence, (a) debt issued by partnerships that derive at least 75% of their gross income from sources that constitute qualifying income for purposes of the 75% gross income test, and (b) debt that is issued by any partnership, to the extent of our interest as a partner in the partnership, are not considered securities.

Debt will meet the “straight debt” safe harbor if (1) neither we, nor any of our controlled taxable REIT subsidiaries (i.e., taxable REIT subsidiaries more than 50% of the vote or value of the outstanding stock of which is directly or indirectly owned by us), own any securities not described in the preceding paragraph that have an aggregate value greater than one percent of the issuer’s outstanding securities, as calculated under the Code, (2) the debt is a written unconditional promise to pay on demand or on a specified date a sum certain in money, (3) the debt is not convertible, directly or indirectly, into stock, and (4) the interest rate and the interest payment dates of the debt are not contingent on the profits, the borrower’s discretion or similar factors. However, contingencies regarding time of payment and interest are permissible for purposes of qualifying as a straight debt security if either (1) such contingency does not have the effect of changing the effective yield of maturity, as determined under the Code, other than a change in the annual yield to maturity that does not exceed the greater of (i) 5% of the annual yield to maturity or (ii) 0.25%, or (2) neither the aggregate issue price nor the aggregate face amount of the issuer’s debt instruments held by the REIT exceeds $1,000,000 and not more than 12 months of

51

unaccrued interest can be required to be prepaid thereunder. In addition, debt will not be disqualified from being treated as “straight debt” solely because the time or amount of payment is subject to a contingency upon a default or the exercise of a prepayment right by the issuer of the debt, provided that such contingency is consistent with customary commercial practice.

We currently own approximately 41% of the common equity of PS Business Parks, Inc., which has elected to be taxed as a REIT for U.S. federal income tax purposes (as well as a substantial portion of the outstanding common units of limited partnership interest of PS Business Parks, L.P., which may be exchangeable for shares of PS Business Parks, Inc.’s common stock). As a REIT, PS Business Parks, Inc. is subject to the various REIT qualification requirements. We believe that PS Business Parks, Inc. has been organized and has operated in a manner to qualify for taxation as a REIT for U.S. federal income tax purposes and will continue to be organized and operated in this manner. If PS Business Parks, Inc. were to fail to qualify as a REIT, our stock investment in PS Business Parks, Inc. would cease to be a qualifying real estate asset for purposes of the 75% gross asset test and would become subject to the 5% asset test, the 10% voting securities test, and the 10% value test generally applicable to our ownership in corporations (other than REITs, qualified REIT subsidiaries and taxable REIT subsidiaries). If PS Business Parks, Inc. failed to qualify as a REIT, we would not meet the 10% voting securities test and the 10% value test with respect to our interest in PS Business Parks, Inc., and accordingly, we also would fail to qualify as a REIT.

We believe that the aggregate value of our interests in our taxable REIT subsidiaries does not exceed, and in the future will not exceed, 20% of the aggregate value of our gross assets. As of each relevant testing date prior to the election to treat each corporate subsidiary of Public Storage or any other corporation in which we own an interest as a taxable REIT subsidiary, we believe we did not own more than 10% of the voting securities of any such entity. In addition, we believe that as of each relevant testing date prior to the election to treat each corporate subsidiary of Public Storage or any other corporation in which we own an interest as a taxable REIT subsidiary of Public Storage, our pro rata share of the value of the securities, including debt, of any such corporation or other issuer did not exceed 5% of the total value of our assets.

With respect to each issuer in which we currently own an interest that does not qualify as a REIT, a qualified REIT subsidiary or a taxable REIT subsidiary, we believe that our pro rata share of the value of the securities, including debt, of any such issuer does not exceed 5% of the total value of our assets and that it complies with the 10% voting securities test and 10% value test with respect to each such issuer. However, no independent appraisals have been obtained to support these conclusions. In this regard, however, we cannot provide any assurance that the IRS might not disagree with our determinations.

The asset tests must be satisfied not only on the last day of the calendar quarter in which we, directly or through pass-through subsidiaries, acquire securities in the applicable issuer, but also on the last day of the calendar quarter in which we increase our ownership of securities of such issuer, including as a result of increasing our interest in pass-through subsidiaries. After initially meeting the asset tests at the close of any quarter, we will not lose our status as a REIT for failure to satisfy the asset tests solely by reason of changes in the relative values of our assets. If failure to satisfy the asset tests results from an acquisition of securities or other property during a quarter, we can cure this failure by disposing of sufficient non-qualifying assets within 30 days after the close of that quarter. We intend to maintain adequate records of the value of our assets to ensure compliance with the asset tests and to take any available action within 30 days after the close of any quarter as may be required to cure any noncompliance with the asset tests. Although we plan to take steps to ensure that we satisfy such tests for any quarter with respect to which testing is to occur, there can be no assurance that such steps will always be successful. If we fail to timely cure any noncompliance with the asset tests, we would cease to qualify as a REIT, unless we satisfy certain relief provisions described in the next paragraph.

The failure to satisfy the asset tests can be remedied even after the 30-day cure period under certain circumstances. If the total value of the assets that caused a failure of the 5% asset test, the 10% voting securities test or the 10% value test does not exceed either 1% of our assets at the end of the relevant quarter or

$10,000,000, we can cure such a failure by disposing of sufficient assets to cure such a violation within six months following the last day of the quarter in which we first identify the failure of the asset test. If we fail any of the other asset tests or our failure of the 5% and 10% asset tests is in excess of the de minimis amount described above, we can avoid disqualification as a REIT if the violation is due to reasonable cause and we dispose of an amount of assets sufficient to cure such violation within the six-month period described in the preceding sentence, pay a tax equal to the greater of $50,000 or the highest corporate tax rate multiplied by the net income generated by the nonqualifying assets during the period of time that the assets were held as nonqualifying assets, and file in accordance with applicable Treasury regulations a schedule with the IRS that describes the assets. The applicable Treasury regulations are yet to be issued. Thus, it is not possible to state with precision under what circumstances we would be entitled to the benefit of these provisions.

Annual Distribution Requirements Applicable to REITs. To qualify as a REIT, we are required to distribute dividends, other than capital gain dividends, to our shareholders each year in an amount at least equal to the sum of:

In addition, for purposes of this test, non-cash income includes a portion of the income attributable to leveled stepped rents, original issue discount included in our taxable income and certain income attributable to an investment in a residual interest in a REMIC, in both cases without the receipt of a corresponding payment, cancellation of indebtedness, and income from a like-kind exchange that is later determined to be taxable (provided, in this last case, that the failure to qualify as a like-kind exchange was due to reasonable cause and not willful neglect). We must pay these distributions in the taxable year to which they relate, or in the following taxable year if they are declared during the last three months of the taxable year, payable to shareholders of record on a specified date during such period and paid during January of the following year. Such distributions are treated as paid by us and received by our shareholders on December 31 of the year in which they are declared. In addition, at our election, a distribution for a taxable year may be declared before we timely file our tax return for such year and paid on or before the first regular dividend payment date after such declaration, provided such payment is made during the twelve-month period following the close of such year. These distributions are treated as being received by our shareholders in the year in which paid. This is so even though these distributions relate to the prior year for purposes of our 90% distribution requirement.

To the extent that we either do not distribute all of our net capital gain or we distribute at least 90%, but less than 100%, of our “REIT taxable income,” as adjusted, we will be required to pay tax on that amount at regular corporate tax rates. We intend to make timely distributions sufficient to satisfy these annual distribution requirements. In years prior to 1990, we made distributions in excess of our REIT taxable income. During 1990, we reduced the level of distributions to our shareholders. As a result, distributions paid by us in 1990 were less than 95% of our REIT taxable income for 1990. The same circumstance existed with respect to each year through 2012, with the exception of 2003, 2004 and 2006. We satisfied the REIT distribution requirements for 1990 through 2012 where necessary by attributing distributions in 1991 through 2013 to the prior year’s taxable income. We may be required to continue this pattern of making distributions after the close of a taxable year that are attributed to the prior year for this purpose, but shareholders will be treated for U.S. federal income tax purposes as having received such distributions in the taxable years in which they actually are made. The extent to which we will be required to attribute distributions to the prior year will depend on our operating results and the level of distributions as determined by the board of trustees. As noted below, reliance on subsequent year distributions could cause us to be subject to an excise tax, although we intend to comply with the 85% current distribution requirement under the excise tax in an effort to avoid or minimize any effect of that tax.

53

To the extent that in the future we may have available net operating losses carried forward from prior taxable years, such losses may reduce the amount of distributions that we must make in order to comply with the REIT distribution requirements. Such losses, however, (1) will generally not affect the character, in the hands of our shareholders, of any distributions that are actually made as ordinary dividends or capital gains; and (2) cannot be passed through or used by our shareholders. Under Section 172 of the Code, our deduction for any net operating loss carryforwards arising from losses we sustain in taxable years beginning after December 31, 2017, is limited to 80% of our REIT taxable income (determined without regard to the deduction for dividends paid), and any unused portion of losses may be carried forward indefinitely.

We intend to make timely distributions sufficient to satisfy our annual distribution requirements. Although we anticipate that our cash flow will permit us to make those distributions, it is possible that, from time to time, we may not have sufficient cash or other liquid assets to meet these distribution requirements. Furthermore, under Section 451 of the Code, subject to certain exceptions, we must accrue income for U.S. federal income tax purposes no later than when such income is taken into account as revenue in our financial statements, which could create additional differences between REIT taxable income and the receipt of cash attributable to such income. In addition, Section 162(m) of the Code places a per-employee limit of $1 million on the amount of compensation that a publicly held corporation may deduct in any one year with respect to its chief executive officer and certain other highly compensated executive officers. Recent changes to Section 162(m) eliminated an exception that formerly permitted certain performance-based compensation to be deducted even if in excess of $1 million, which may have the effect of increasing our REIT taxable income. If these timing differences occur, we may find it necessary to arrange for short-term, or possibly long-term, borrowings to fund required distributions or to pay dividends in the form of taxable dividends of our shares.

Under some circumstances, we may be able to rectify an inadvertent failure to meet the distribution requirement for a year by paying “deficiency dividends” to our shareholders in a later year, which may be included in our deduction for dividends paid for the earlier year. Thus, we may be able to avoid being taxed on amounts distributed as deficiency dividends. However, we will be required to pay interest to the IRS based upon the amount of any deduction claimed for deficiency dividends.

We will be subject to a 4% nondeductible excise tax on the excess of the required distribution over the sum of amounts actually distributed, excess distributions from the preceding tax year and amounts retained for which U.S. federal income tax was paid if we fail to make the required distribution by the end of a calendar year (taking into account certain distributions declared in the last three months of a calendar year and paid prior to the end of January of the following calendar year). The required distribution for each calendar year is equal to the sum of:

A REIT may elect to retain rather than distribute all or a portion of its net capital gains and pay the tax on the gains. In that case, a REIT may elect to have its shareholders include their proportionate share of the undistributed net capital gains in income as long-term capital gains and receive a credit for their share of the tax paid by the REIT. For purposes of the 4% excise tax described above, any retained amounts would be treated as having been distributed.

Interest Deduction Limitation. Section 163(j) of the Code limits the deductibility of net interest expense paid or accrued on debt properly allocable to a trade or business to 30% of “adjusted taxable income,” subject to certain exceptions. Any deduction in excess of the limitation is carried forward and may be used in a subsequent year, subject to the 30% limitation. Adjusted taxable income is determined without regard to certain deductions, including those for net interest expense, and net operating loss carryforwards. Provided the taxpayer makes a timely election (which is irrevocable), the 30% limitation does not apply to a trade or business involving real

54

property development, redevelopment, construction, reconstruction, rental, operation, acquisition, conversion, disposition, management, leasing or brokerage, within the meaning of Section 469(c)(7)(C) of the Code. If this election is made, depreciable real property (including certain improvements) held by the relevant trade or business must be depreciated under the alternative depreciation system under the Code, which is generally less favorable than the generally applicable system of depreciation under the Code. If we do not make the election or if the election is determined not to be available with respect to all or certain of our business activities, the interest deduction limitation could result in us having more REIT taxable income and thus increase the amount of distributions we must make to comply with the REIT requirements and avoid incurring corporate level tax. Similarly, the limitation could cause our taxable REIT subsidiaries to have greater taxable income and thus potentially greater corporate tax liability.

On March 27, 2020, Section 163(j) was further amended by Section 2306 of the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) to increase the 30% interest deduction limitation to 50% for taxable years 2019 and 2020 (the increase applies to partnerships only for taxable year 2020). The CARES Act also made an election available to taxpayers to use their 2019 adjusted taxable income as their adjusted taxable income in 2020 for purposes of applying the limitation.

Record-Keeping Requirements. We are required to comply with applicable record-keeping requirements. Failure to comply could result in monetary fines.

Failure of Public Storage to Qualify as a REIT. If we fail to comply with one or more of the conditions required for qualification as a REIT (other than asset tests and the income tests that have the specific savings clauses discussed above in “—Asset Tests Applicable to REITs,” and “—Income Tests Applicable to REITs”), we can avoid termination of our REIT status by paying a penalty of $50,000 for each such failure, provided that our noncompliance was due to reasonable cause and not willful neglect. If we fail to qualify for taxation as a REIT in any taxable year and the statutory relief provisions do not apply, we will be subject to tax, including any applicable alternative minimum tax for taxable years beginning prior to December 31, 2017, on our taxable income at regular corporate rates. Distributions to shareholders in any year in which we fail to qualify will not be deductible by us, and we will not be required to distribute any amounts to our shareholders. As a result, our failure to qualify as a REIT would significantly reduce the cash available for distribution by us to our shareholders. In addition, if we fail to qualify as a REIT, all distributions to shareholders will be taxable as regular corporate dividends to the extent of our current and accumulated earnings and profits. For taxable years beginning before January 1, 2026, generally U.S. shareholders that are individuals, trusts or estates may deduct 20% of the aggregate amount of ordinary dividends distributed by us, subject to certain limitations. Alternatively, such dividends paid to U.S. shareholders that are individuals, trusts and estates may be taxable at the preferential income tax rates (i.e., the 20% maximum U.S. federal rate) for qualified dividends. In addition, subject to the limitations of the Code, corporate distributees may be eligible for the dividends-received deduction.

Unless entitled to relief under specific statutory provisions, we will also be disqualified from taxation as a REIT for the four taxable years following the year during which we lost our qualification. There can be no assurance that we would be entitled to any statutory relief.

Taxation of U.S. Shareholders

55

Notwithstanding the preceding sentence, to the extent provided in the Treasury regulations, certain trusts in existence on August 20, 1996, and treated as U.S. persons prior to this date that elect to continue to be treated as U.S. persons, shall also be considered U.S. shareholders.

If you hold our common shares and are not a U.S. shareholder, you are a “non-U.S. shareholder.” If a partnership holds our common shares, the tax treatment of a partner in the partnership will generally depend upon the status of the partner and the activities of the partnership. If you are a partner of a partnership holding our common shares, you should consult your tax advisor regarding the tax consequences of the ownership and disposition of our common shares.

Distributions by Public Storage—General. As long as we qualify as a REIT, distributions out of our current or accumulated earnings and profits that are not designated as capital gains dividends or “qualified dividend income” will be taxable to our taxable U.S. shareholders as ordinary income and will not be eligible for the dividends-received deduction in the case of U.S. shareholders that are corporations. However, for taxable years prior to 2026, generally U.S. shareholders that are individuals, trusts or estates may deduct 20% of the aggregate amount of ordinary dividends distributed by us, subject to certain limitations. For purposes of determining whether distributions to holders of common shares or equity shares are out of current or accumulated earnings and profits, our earnings and profits will be allocated first to our outstanding preferred shares and then to our outstanding common shares and equity shares.

To the extent that we make distributions in excess of our current and accumulated earnings and profits, these distributions will be treated first as a tax-free return of capital to each U.S. shareholder. This treatment will reduce the adjusted tax basis that each U.S. shareholder has in its shares for tax purposes by the amount of the distribution, but not below zero. Distributions in excess of a U.S. shareholder’s adjusted tax basis in its shares will be taxable as capital gains, provided that the shares have been held as a capital asset, and will be taxable as long-term capital gain if the shares have been held for more than one year. Dividends we declare in October, November, or December of any year that are payable to a shareholder of record on a specified date in any of these months shall be treated as both paid by us and received by the shareholder on December 31 of that year, provided we actually pay the dividend on or before January 31 of the following calendar year.

Capital Gain Distributions. We may elect to designate distributions of our net capital gain as “capital gain dividends.” Distributions that we properly designate as “capital gain dividends” will be taxable to our taxable U.S. shareholders as gain from the sale or disposition of a capital asset to the extent that such gain does not exceed our actual net capital gain for the taxable year. Designations made by us will only be effective to the extent that they comply with Revenue Ruling 89-81, which requires that distributions made to different classes of shares be composed proportionately of dividends of a particular type. If we designate any portion of a dividend as a capital gain dividend, a U.S. shareholder will receive an IRS Form 1099-DIV indicating the amount that will be taxable to the shareholder as capital gain. Corporate shareholders, however, may be required to treat up to 20% of some capital gain dividends as ordinary income.

Instead of paying capital gain dividends, we may designate all or part of our net capital gain as “undistributed capital gain.” We will be subject to tax at regular corporate rates on any undistributed capital gain. A U.S. shareholder will include in its income as long-term capital gains its proportionate share of such undistributed capital gain and will be deemed to have paid its proportionate share of the tax paid by us on such undistributed capital gain and receive a credit or a refund to the extent that the tax paid by us exceeds the U.S. shareholder’s tax liability on the undistributed capital gain. A U.S. shareholder will increase the basis in its common shares by the difference between the amount of capital gain included in its income and the amount of

56

tax it is deemed to have paid. A U.S. shareholder that is a corporation will appropriately adjust its earnings and profits for the retained capital gain in accordance with Treasury regulations to be prescribed by the IRS. Our earnings and profits will be adjusted appropriately.

We will classify portions of any designated capital gain dividend or undistributed capital gain as either:

We must determine the maximum amounts that we may designate as 20% and 25% rate capital gain dividends by performing the computation required by the Code as if the REIT were an individual whose ordinary income were subject to a marginal tax rate of at least 28%.

Recipients of capital gain dividends from us that are taxed at corporate income tax rates will be taxed at the normal corporate income tax rates on those dividends. The maximum amount of dividends that we may designate as capital gain and as “qualified dividend income” (discussed below) with respect to any taxable year (effective for distributions in tax years beginning after December 31, 2014) may not exceed the dividends actually paid by us with respect to such year, including dividends paid by us in the succeeding tax year that relate back to the prior tax year for purposes of determining our dividends-paid deduction.

Qualified Dividend Income. With respect to shareholders who are taxed at the rates applicable to individuals, we may elect to designate a portion of our distributions paid to shareholders as “qualified dividend income.” A portion of a distribution that is properly designated as qualified dividend income is taxable to non-corporate U.S. shareholders as capital gain, provided that the shareholder has held the common shares with respect to which the distribution is made for more than 60 days during the 121-day period beginning on the date that is 60 days before the date on which such common shares become ex-dividend with respect to the relevant distribution. The maximum amount of our distributions eligible to be designated as qualified dividend income for a taxable year is equal to the sum of:

Generally, dividends that we receive will be treated as qualified dividend income for purposes of (1) above if the dividends are received from a domestic corporation (other than a REIT or a regulated investment company) or a “qualified foreign corporation” and specified holding period requirements and other requirements are met. A foreign corporation (other than a “passive foreign investment company”) will be a qualified foreign corporation if it is incorporated in a possession of the United States, the corporation is eligible for benefits of an income tax treaty with the United States that the Secretary of Treasury determines is satisfactory, or the stock of the foreign corporation on which the dividend is paid is readily tradable on an established securities market in the United States. We generally expect that an insignificant portion, if any, of our distributions will consist of qualified dividend income. If we designate any portion of a dividend as qualified dividend income, a U.S. shareholder will receive an IRS Form 1099-DIV indicating the amount that will be taxable to the shareholder as qualified dividend income.

57

Other Tax Considerations. Distributions we make and gain arising from the sale or exchange by a U.S. shareholder of our shares will not be treated as passive activity income. As a result, U.S. shareholders generally will not be able to apply any “passive losses” against this income or gain. Distributions we make, to the extent they do not constitute a return of capital, generally will be treated as investment income for purposes of computing the investment interest limitation. A U.S. shareholder may elect, depending on its particular situation, to treat capital gain dividends, capital gains from the disposition of shares and income designated as qualified dividend income as investment income for purposes of the investment interest limitation, in which case the applicable capital gains will be taxed at ordinary income rates. We will notify shareholders regarding the portions of our distributions for each year that constitute ordinary income, return of capital and qualified dividend income. U.S. shareholders may not include in their individual income tax returns any of our net operating losses or capital losses. Our operating or capital losses would be carried over by us for potential offset against future income, subject to applicable limitations.

Sales of Shares. If a U.S. shareholder sells or otherwise disposes of its shares in a taxable transaction, it will recognize gain or loss for U.S. federal income tax purposes in an amount equal to the difference between the amount of cash and the fair market value of any property received on the sale or other disposition and the holder’s adjusted basis in the shares for tax purposes. This gain or loss will be a capital gain or loss if the shares have been held by the U.S. shareholder as a capital asset. The applicable tax rate will depend on the U.S. shareholder’s holding period in the asset (generally, if an asset has been held for more than one year, such gain or loss will be long-term capital gain or loss) and the U.S. shareholder’s tax bracket. A U.S. shareholder who is an individual or an estate or trust and who has long-term capital gain or loss will be subject to a maximum capital gain rate of 20%. The IRS has the authority to prescribe, but has not yet prescribed, regulations that would apply a capital gain tax rate of 25% (which is generally higher than the long-term capital gain tax rates for noncorporate shareholders) to a portion of capital gain realized by a noncorporate shareholder on the sale of REIT shares that would correspond to the REIT’s “unrecaptured Section 1250 gain.” In general, any loss recognized by a U.S. shareholder upon the sale or other disposition of common shares that have been held for six months or less, after applying the holding period rules, will be treated by such U.S. shareholders as a long-term capital loss, to the extent of distributions received by the U.S. shareholder from us that were required to be treated as long-term capital gains. Shareholders are advised to consult their tax advisors with respect to the capital gain liability.

Expansion of Medicare Tax. The Health Care and Reconciliation Act of 2010 requires that, in certain circumstances, certain U.S. shareholders that are individuals, estates, and trusts pay a 3.8% tax on “net investment income,” which includes, among other things, dividends on and gains from the sale or other disposition of stock. The temporary 20% deduction allowed by Section 199A of the Code with respect to ordinary REIT dividends received by non-corporate taxpayers is allowed only for purposes of Chapter 1 of the Code and thus is apparently not allowed as a deduction allocable to such dividends for purposes of determining the amount of net investment income subject to the 3.8% Medicare tax, which is imposed under Chapter 2A of the Code. Prospective investors should consult with their own tax advisors regarding this legislation.

Foreign Accounts. Certain payments made to “foreign financial institutions” in respect of accounts of U.S. shareholders at such financial institutions may be subject to withholding at a rate of 30%. U.S. shareholders should consult their tax advisors regarding the effect, if any, of these withholding provisions on their ownership and disposition of their shares. See “—U.S. Taxation of Non-U.S. Shareholders—Withholding on Payments to Certain Foreign Entities.”

Taxation of Tax-Exempt Shareholders

Provided that a tax-exempt shareholder, except certain tax-exempt shareholders described below, has not held its common shares as “debt-financed property” within the meaning of the Code and the shares are not otherwise used in its trade or business, the dividend income from us and gain from the sale of our common shares will not be unrelated business taxable income (“UBTI”) to a tax-exempt shareholder. Generally, “debt-financed

58

property” is property, the acquisition or holding of which was financed through a borrowing by the tax-exempt shareholder.

For tax-exempt shareholders that are social clubs, voluntary employee benefit associations, or supplemental unemployment benefit trusts exempt from U.S. federal income taxation under Sections 501(c)(7), (c)(9), or (c)(17) of the Code, respectively, or single parent title-holding corporations exempt under Section 501(c)(2) and whose income is payable to any of the aforementioned tax-exempt organizations, income from an investment in Public Storage will constitute unrelated business taxable income unless the organization is able to properly claim a deduction for amounts set aside or placed in reserve for certain purposes so as to offset the income generated by its investment in our shares. These prospective investors should consult with their tax advisors concerning these set aside and reserve requirements.

Notwithstanding the above, however, a portion of the dividends paid by a “pension-held REIT” are treated as UBTI if received by any trust which is described in Section 401(a) of the Code, is tax-exempt under Section 501(a) of the Code and holds more than 10%, by value, of the interests in the REIT. A pension-held REIT includes any REIT if:

The percentage of any REIT dividend from a “pension-held REIT” that is treated as UBTI is equal to the ratio of the UBTI earned by the REIT, treating the REIT as if it were a pension trust and therefore subject to tax on UBTI, to the total gross income of the REIT. An exception applies where the percentage is less than 5% for any year, in which case none of the dividends would be treated as UBTI. The provisions requiring pension trusts to treat a portion of REIT distributions as UBTI will not apply if the REIT is able to satisfy the “not closely held requirement” without relying upon the “look-through” exception with respect to pension trusts. As a result of certain limitations on the transfer and ownership of our shares contained in our organizational documents, we do not expect to be classified as a “pension-held REIT,” and accordingly, the tax treatment described above should be inapplicable to our tax-exempt shareholders.

U.S. Taxation of Non-U.S. Shareholders

The following discussion addresses the rules governing U.S. federal income taxation of the ownership and disposition of our common shares by non-U.S. shareholders. These rules are complex, and no attempt is made herein to provide more than a brief summary of such rules. Accordingly, the discussion does not address all aspects of U.S. federal income taxation and does not address state, local or foreign tax consequences that may be relevant to a non-U.S. shareholder in light of its particular circumstances.

Distributions by Public Storage. As described in the discussion below, distributions paid by us with respect to our common shares will be treated for U.S. federal income tax purposes as either:

This discussion assumes that our shares will continue to be considered regularly traded on an established securities market located in the U.S. for purposes of the Foreign Investment in Real Property Tax Act (“FIRPTA”) provisions described below. If our shares are no longer regularly traded on an established securities market located in the U.S., the tax considerations described below would differ.

59

Ordinary Income Dividends. A distribution paid by us to a non-U.S. shareholder will be treated as an ordinary income dividend if the distribution is paid out of our current or accumulated earnings and profits and:

Ordinary dividends that are effectively connected with a U.S. trade or business of the non-U.S. shareholder will be subject to tax on a net basis (that is, after allowance for deductions) at graduated rates in the same manner as U.S. shareholders (including any applicable alternative minimum tax), except that a non-U.S. shareholder that is a corporation also may be subject to a branch profits tax at a rate of 30% (or lower applicable treaty rate).

Generally, we will withhold and remit to the IRS 30% of dividend distributions (including distributions that may later be determined to have been made in excess of current and accumulated earnings and profits) that could not be treated as capital gain distributions with respect to the non-U.S. shareholder (and that are not deemed to be capital gain dividends for purposes of the FIRPTA withholding rules described below) unless:

Return of Capital Distributions. A distribution in excess of our current and accumulated earnings and profits will be taxable to a non-U.S. shareholder, if at all, as gain from the sale of common shares to the extent that the distribution exceeds the non-U.S. shareholder’s basis in its common shares (and, as a general matter, subject to U.S. federal income tax as described below in the section entitled “–Sale of Common Shares”). A distribution in excess of our current and accumulated earnings and profits will reduce the non-U.S. shareholder’s basis in its common shares and will not be subject to U.S. federal income to the extent it reduces such non-U.S. shareholder’s basis in its common shares.

We may be required to withhold at least 15% of any distribution in excess of our current and accumulated earnings and profits, even if a lower treaty rate applies and the non-U.S. shareholder is not liable for tax on the receipt of that distribution. Moreover, if we cannot determine at the time a distribution is made whether or not the distribution will exceed our current and accumulated earnings and profits, we will withhold on the distribution at a rate not less than that applicable to ordinary income dividends. However, as a general matter, the non-U.S. shareholder may seek a refund of these amounts from the IRS if the non-U.S. shareholder’s U.S. tax liability with respect to the distribution is less than the amount withheld.

Capital Gain Dividends. A distribution paid by us to a non-U.S. shareholder will be treated as long-term capital gain if the distribution is paid out of our current or accumulated earnings and profits and:

Long-term capital gain that a non-U.S. shareholder is deemed to receive from a capital gain dividend that is not attributable to the sale of USRPI generally will not be subject to U.S. tax in the hands of the non-U.S. shareholder unless:

60

Under FIRPTA, distributions that are attributable to gain from the sales by us of USRPIs and paid to a non-U.S. shareholder that owns more than 10% of the value of the relevant class of shares at any time during the one-year period ending on the date of the distribution will be subject to U.S. tax as income effectively connected with a U.S. trade or business. The FIRPTA tax will apply to these distributions whether or not the distribution is designated as a capital gain dividend.

Any distribution paid by us that is treated as a capital gain dividend or that could be treated as a capital gain dividend with respect to a particular non-U.S. shareholder that owns more than 10% of the value of the relevant class of shares at any time during the one-year period ending on the date of the distribution will be subject to special withholding rules under FIRPTA. We will be required to withhold and remit to the IRS 21% of any distribution that could be treated as a capital gain dividend with respect to the non-U.S. shareholder, whether or not the distribution is attributable to the sale by us of USRPIs. The amount withheld is creditable against the non-U.S. shareholder’s U.S. federal income tax liability or refundable when the non-U.S. shareholder properly and timely files a tax return with the IRS. In addition, distributions to certain non-U.S. publicly traded shareholders that meet certain record-keeping and other requirements (“qualified shareholders”) are exempt from FIRPTA, except to the extent owners of such qualified shareholders that are not also qualified shareholders own, actually or constructively, more than 10% of our shares. Furthermore, distributions to “qualified foreign pension funds” (as defined in the Code) or entities all of the interests of which are held by “qualified foreign pension funds” are exempt from FIRPTA. Non-U.S. shareholders should consult their tax advisors regarding the application of these rules.

Undistributed Capital Gain. Although the law is not entirely clear on the matter, it appears that amounts designated by us as undistributed capital gains in respect of our shares held by non-U.S. shareholders generally should be treated in the same manner as actual distributions by us of capital gain dividends. Under that approach, the non-U.S. shareholder would be able to offset as a credit against its U.S. federal income tax liability resulting therefrom its proportionate share of the tax paid by us on the undistributed capital gains treated as long-term capital gain to the non-U.S. shareholder, and generally to receive from the IRS a refund to the extent its proportionate share of the tax paid by us were to exceed the non-U.S. shareholder’s actual U.S. federal income tax liability on such long-term capital gain. If we were to designate any portion of our net capital gain as undistributed capital gain, a non-U.S. shareholder should consult its tax advisor regarding the taxation of such undistributed capital gain.

Sale of Common Shares. Gain recognized by a non-U.S. shareholder upon the sale or exchange of our common shares generally would not be subject to U.S. taxation unless:

Our common shares will not constitute a USRPI if we are a domestically controlled REIT. We intend to take the position that we will be a domestically controlled REIT if, at all times during a specified testing period, less

61

than 50% in value of our common shares is held directly or indirectly by non-U.S. shareholders. Our charter contains restrictions designed to protect our status as a domestically-controlled REIT, and we believe that we are a domestically-controlled REIT. If we are a domestically-controlled REIT, gain recognized by a non-U.S. holder upon the sale or exchange of our common shares generally would not be subject to tax under FIRPTA. However, because our common shares are publicly traded, no assurance can be given that we are or will be a domestically controlled REIT. Even if we were not a domestically controlled REIT, a sale of our common shares by a non-U.S. shareholder would nevertheless not be subject to taxation under FIRPTA as a sale of a USRPI if:

In addition, dispositions of our shares by qualified shareholders are exempt from FIRPTA, except to the extent owners of such qualified shareholders that are not also qualified shareholders own, actually or constructively, more than 10% of our shares. An actual or deemed disposition of our shares by such shareholders may also be treated as a dividend. Furthermore, dispositions of our shares by “qualified foreign pension funds” or entities all of the interests of which are held by “qualified foreign pension funds” are exempt from FIRPTA. Non-U.S. shareholders should consult their tax advisors regarding the application of these rules.

We believe that we are and will continue to be a domestically controlled qualified investment entity and, therefore, that the sale of our common shares by a non-U.S. shareholder would not be subject to taxation under FIRPTA. Because our shares are publicly traded, however, we cannot guarantee that we are or will continue to be a domestically controlled qualified investment entity. If gain on the sale or exchange of our common shares were subject to taxation under FIRPTA, the non-U.S. shareholder would be subject to regular U.S. federal income tax with respect to any gain in the same manner as a taxable U.S. shareholder, subject to any applicable alternative minimum tax and special alternative minimum tax in the case of nonresident alien individuals. In such case, under FIRPTA the purchaser of common shares may be required to withhold 15% of the purchase price and remit this amount to the IRS.

Specific wash sale rules applicable to sales of shares in a domestically-controlled REIT could result in gain recognition, taxable under FIRPTA, upon the sale of our common shares even if we are a domestically-controlled qualified investment entity. These rules would apply if a non-U.S. shareholder (1) disposes of our common shares within a 30-day period preceding the ex-dividend date of a distribution, any portion of which, but for the disposition, would have been taxable to such non-U.S. shareholder as gain from the sale or exchange of a USRPI, (2) acquires, or enters into a contract or option to acquire, other common shares during the 61-day period that begins 30 days prior to such ex-dividend date, and (3) if our common shares are “regularly traded” on an established securities market in the United States, such non-U.S. shareholder has owned more than 10% of our outstanding common shares at any time during the one-year period ending on the date of such distribution.

If gain on the sale or exchange of our common shares by a non-U.S. shareholder were subject to taxation under FIRPTA, the non-U.S. shareholder generally would be subject to regular U.S. federal income tax with respect to any gain on a net basis in the same manner as a taxable U.S. shareholder, subject to any applicable alternative minimum tax and special alternative minimum tax in the case of nonresident alien individuals. In addition, the transferee of such stock may, in certain circumstances, be required to withhold at least 15% of the proceeds of any such sale or exchange. However, the non-U.S. shareholder generally may seek a refund of these amounts from the IRS if the non-U.S. shareholder’s U.S. tax liability with respect to the distribution is less than the amount withheld.

Withholding on Payments to Certain Foreign Entities. The Foreign Account Tax Compliance Act (“FATCA”) imposes a 30% withholding tax on certain types of payments made to “foreign financial institutions”

62

and certain other non-U.S. entities unless certain due diligence, reporting, withholding, and certification requirements are satisfied.

Under the applicable Treasury regulations and administrative guidance, FATCA imposes a 30% withholding tax on dividends on, and (subject to the proposed Treasury regulations discussed below) gross proceeds from the sale or other disposition of, our shares if paid to a foreign entity unless: (i) the foreign entity is a “foreign financial institution” that undertakes certain due diligence, reporting, withholding, and certification obligations, or in the case of a foreign financial institution that is a resident in a jurisdiction that has entered into an intergovernmental agreement to implement FATCA, the entity complies with the diligence and reporting requirements of such agreement, (ii) the foreign entity is not a “foreign financial institution” and either certifies it does not have any “substantial United States owners” (as defined in the Code) or identifies certain of its U.S. investors, or (iii) the foreign entity otherwise is exempted under FATCA. While withholding under FATCA would have applied also to payments of gross proceeds from the sale or other disposition of our shares on or after January 1, 2019, proposed Treasury regulations eliminate FATCA withholding on payments of gross proceeds entirely. Taxpayers generally may rely on these proposed Treasury regulations until final Treasury regulations are issued.

If withholding is required under FATCA on a payment related to our shares, investors that otherwise would not be subject to withholding (or that otherwise would be entitled to a reduced rate of withholding) generally will be required to seek a refund or credit from the IRS to obtain the benefit of such exemption or reduction (provided that such benefit is available). Prospective investors should consult their tax advisors regarding the effect of FATCA in their particular circumstances.

Information Reporting and Backup Withholding Tax Applicable to Shareholders

U.S. Shareholders. In general, information-reporting requirements will apply to payments of distributions on our common shares and payments of the proceeds of the sale of our common shares to some U.S. shareholders, unless an exception applies. Further, the payer will be required to withhold backup withholding tax on such payments at the rate of 24% if:

Some shareholders, including corporations, may be exempt from backup withholding. Any amounts that we withhold under the backup withholding rules may be refunded or credited against the U.S. shareholder’s U.S. federal income tax liability if certain required information is timely furnished to the IRS.

Non-U.S. Shareholders. Generally, information reporting will apply to payments of distributions on our common shares, and backup withholding described above for a U.S. shareholder will apply, unless the payee certifies that it is not a U.S. person or otherwise establishes an exemption.

The payment of the proceeds from the disposition of our common shares to or through the U.S. office of a U.S. or foreign broker will be subject to information reporting and, possibly, backup withholding as described above for U.S. shareholders, or the withholding tax for non-U.S. shareholders, as applicable, unless the non-U.S. shareholder certifies as to its non-U.S. status or otherwise establishes an exemption, provided that the broker does not have actual knowledge that the shareholder is a U.S. person or that the conditions of any other

63

exemption are not, in fact, satisfied. The proceeds of the disposition by a non-U.S. shareholder of our common shares to or through a foreign office of a broker generally will not be subject to information reporting or backup withholding. However, if the broker is a U.S. person, a controlled foreign corporation for U.S. tax purposes, or a foreign person 50% or more of whose gross income from all sources for specified periods is from activities that are effectively connected with a U.S. trade or business, a foreign partnership 50% or more of whose interests are held by partners who are U.S. persons, or a foreign partnership that is engaged in the conduct of a trade or business in the U.S., then information reporting generally will apply as though the payment was made through a U.S. office of a U.S. or foreign broker unless the broker has documentary evidence as to the non-U.S. shareholder’s foreign status and has no actual knowledge to the contrary.

Applicable Treasury regulations provide presumptions regarding the status of shareholders when payments to the shareholders cannot be reliably associated with appropriate documentation provided to the payer. If a non-U.S. shareholder fails to comply with the information reporting requirement, payments to such person may be subject to the full withholding tax even if such person might have been eligible for a reduced rate of withholding or no withholding under an applicable income tax treaty. Because the application of these Treasury regulations varies depending on the shareholder’s particular circumstances, you are urged to consult your tax advisor regarding the information reporting requirements applicable to you.

Backup withholding is not an additional tax. Any amounts that we withhold under the backup withholding rules may be refunded or credited against the non-U.S. shareholder’s U.S. federal income tax liability if certain required information is timely furnished to the IRS. Non-U.S. shareholders should consult with their tax advisors regarding application of backup withholding in their particular circumstances and the availability of and procedure for obtaining an exemption from backup withholding under current Treasury regulations.

Other Tax Consequences for Public Storage and Our Shareholders

We may be required to pay tax in various state or local jurisdictions, including those in which we transact business, and our shareholders may be required to pay tax in various state or local jurisdictions, including those in which they reside. Our state and local tax treatment may not conform to the U.S. federal income tax consequences discussed above. In addition, a shareholder’s state and local tax treatment may not conform to the U.S. federal income tax consequences discussed above. Consequently, prospective investors should consult with their tax advisors regarding the effect of state and local tax laws on an investment in our common shares.

A portion of our income is earned through our taxable REIT subsidiaries. The taxable REIT subsidiaries are subject to U.S. federal, state and local income tax at the full applicable corporate rates and to applicable foreign taxes for our foreign subsidiaries. In addition, a taxable REIT subsidiary will be limited in its ability to deduct interest payments in excess of a certain amount made directly or indirectly to us. To the extent that our taxable REIT subsidiaries and we are required to pay foreign, U.S. federal, state or local taxes, we will have less cash available for distribution to shareholders.

Legislative or Other Actions Affecting REITs

The present U.S. federal income tax treatment of REITs may be modified, possibly with retroactive effect, by legislative, judicial or administrative action at any time. The REIT rules are constantly under review by persons involved in the legislative process and by the IRS and the U.S. Treasury Department, which may result in statutory changes as well as revisions to regulations and interpretations. Changes to the U.S. federal tax laws and interpretations thereof could adversely affect an investment in our securities. Investors should consult with their tax advisors regarding the effect of potential changes to the U.S. federal tax laws and on an investment in our shares.

Tax Shelter Reporting

If a holder recognizes a loss as a result of a transaction with respect to our shares of at least (i) for a holder that is an individual, S corporation, trust or a partnership with at least one noncorporate partner, $2 million or more in a single taxable year or $4 million or more in a combination of taxable years, or (ii) for a holder that is either a corporation or a partnership with only corporate partners, $10 million or more in a single taxable year or $20 million or more in a combination of taxable years, such holder may be required to file a disclosure statement with the IRS on Form 8886. Direct shareholders of portfolio securities are in many cases exempt from this reporting requirement, but shareholders of a REIT currently are not excepted. The fact that a loss is reportable under these regulations does not affect the legal determination of whether the taxpayer’s treatment of the loss is proper. Shareholders should consult their tax advisors to determine the applicability of these regulations in light of their individual circumstances.
