PART I

Item 1.    Business.

        The Company.    We are a real estate investment trust, or REIT, formed in 1986 under the laws of the State of Maryland. Our primary business is the ownership and operation of real estate, including office and industrial buildings and leased industrial land. For a discussion and information regarding our operating segments, see our financial statements beginning on page F-1.

        As of December 31, 2011, we owned 516 properties for a total investment of $7.2 billion at cost (less impairments), and a depreciated book value of $6.3 billion. Our portfolio includes 317 office properties with 40.0 million square feet and 199 industrial & other properties with 32.3 million square feet. Our 199 industrial & other properties include 17.9 million square feet of leased industrial and commercial lands in Oahu, Hawaii. Also, 11 of our total properties with 1.8 million square feet are located in Australia. In addition, we owned 9,950,000, or 21.1%, at December 31, 2011, of the common shares of beneficial interest of Government Properties Income Trust, or GOV, a former subsidiary that is now separately listed on the New York Stock Exchange, or the NYSE. GOV is a REIT that owns properties that are majority leased to government tenants.

        Our principal executive offices are located at Two Newton Place, 255 Washington Street, Suite 300, Newton, Massachusetts 02458-1634, and our telephone number is (617) 332-3990.

        Our investment, financing and disposition policies are established by our Board of Trustees and may be changed by our Board of Trustees at any time without shareholder approval. Our investment goals are current income for distribution to shareholders and capital growth from appreciation in the value of properties. Our income is derived primarily from rents.

        Investment Policies.    In evaluating potential investments and asset sales, we consider various factors, including but not limited to the following:

        We attempt to acquire properties which will enhance the diversity of our portfolio with respect to tenants and locations. However, we have no policies which specifically limit the percentage of our assets which may be invested in any individual property, in any one type of property, in properties in one geographic area, in properties leased to any one tenant or in properties leased to an affiliated group of tenants. We have, however, entered into separate agreements with two of our former wholly owned subsidiaries, GOV and Senior Housing Properties Trust, or SNH, that place certain restrictions on our ability to invest, in the case of GOV's agreement, in properties majority leased to government tenants or, in the case of SNH's agreement, in medical office, clinic and biomedical, pharmaceutical and laboratory buildings (subject, in the case of mixed use buildings, to our retaining the right to invest in any mixed use building for which the rentable square footage is less than 50% medical office, clinic

1


Table of Contents

and biomedical, pharmaceutical and laboratory use). We do not believe that these restrictions limit our ability to achieve a diverse portfolio with respect to tenants.

        We generally prefer wholly owned investments in fee interests. However, circumstances may arise in which we may invest in leaseholds, joint ventures, mortgages and other real estate interests. We may invest in real estate joint ventures if we conclude that by doing so we may benefit from the participation of co-venturers or that our opportunity to participate in the investment is contingent on the use of a joint venture structure. We may invest in participating, convertible or other types of mortgages if we conclude that by doing so we may benefit from the cash flow or appreciation in the value of a property which is not available for purchase.

        In the past, we have considered the possibility of entering into mergers or strategic combinations with other companies. We may undertake such considerations in the future. A principal goal of any such transaction will be to increase our revenues and profits and diversify their sources.

        Disposition Policies.    From time to time we consider the sale of properties or investments. Disposition decisions are made based on a number of factors including those set forth above under Investment Policies and the following:

        In addition, under our business management agreement with Reit Management & Research LLC, or RMR, with certain exceptions, if we determine to offer for sale or other disposition any real property that, at such time, is of a type within the investment focus of another REIT to which RMR provides business management or property management services, or an RMR Managed REIT, we will first offer that property for purchase or disposition to that RMR Managed REIT and negotiate in good faith for such purchase or disposition.

        Financing Policies.    We currently have a $750.0 million revolving credit facility (which is guaranteed by most of our subsidiaries) that we use for working capital and general business purposes and for acquisition funding on an interim basis until we refinance with equity or long term debt. This credit facility matures in October 2015, and includes an option for us to extend the facility for one year to October 2016. The annual interest payable for amounts drawn under the facility is LIBOR plus 125 basis points, subject to adjustments based on our credit ratings. At December 31, 2011, $100.0 million was outstanding under our revolving credit facility.

        Our revolving credit facility and term loan agreements and our senior note indenture and its supplements contain financial covenants that, among other things, restrict our ability to incur indebtedness and require us to maintain certain financial ratios and a minimum net worth. Our Board of Trustees may determine to replace our current credit facility or to seek additional capital through equity offerings, debt financings, retention of cash flows in excess of distributions to shareholders or a combination of these methods. Some of our properties are encumbered by mortgages. To the extent that our Board of Trustees decides to obtain additional debt financing, we may do so on an unsecured basis or a secured basis, subject to limitations in existing financing or other contractual arrangements; we may seek to obtain other lines of credit or to issue securities senior to our common and/or preferred shares, including preferred shares or debt securities which may be convertible into common shares or be accompanied by warrants to purchase common shares; or we may engage in transactions which involve a sale or other conveyance of properties to affiliated or unaffiliated entities. We may finance acquisitions by an exchange of properties, by borrowing under our credit facility or by the issuance of additional equity or debt securities. The proceeds from any of our financings may be used

2


Table of Contents

to pay distributions, to provide working capital, to refinance existing indebtedness or to finance acquisitions and expansions of existing or new properties.

        The borrowing guidelines established by our Board of Trustees and covenants in various debt agreements prohibit us from maintaining a debt to total asset value, as defined, of greater than 60%. Our declaration of trust also limits our borrowings. We may from time to time re-evaluate and modify our financing policies in light of then current market conditions, relative availability and costs of debt and equity capital, market values of properties, growth and acquisition opportunities and other factors, and we may increase or decrease our ratio of debt to total capitalization accordingly.

        Manager.    Our day to day operations are conducted by RMR. RMR originates and presents investment and divestment opportunities to our Board of Trustees and provides management and administrative services to us. RMR is a Delaware limited liability company beneficially owned by Barry M. Portnoy and Adam D. Portnoy, our Managing Trustees. Adam D. Portnoy is also our President. RMR has a principal place of business at Two Newton Place, 255 Washington Street, Suite 300, Newton, Massachusetts 02458-1634, and its telephone number is (617) 796-8390. RMR also acts as the manager to GOV, Hospitality Properties Trust, or HPT, and SNH, and provides management services to other public and private companies, including Five Star Quality Care, Inc., or Five Star, TravelCenters of America LLC, or TA, and Sonesta International Hotels Corporation, or Sonesta. Barry M. Portnoy is the Chairman of RMR, and its other directors are Adam D. Portnoy, Gerard M. Martin, formerly one of our Managing Trustees, and David J. Hegarty. The executive officers of RMR are: Adam D. Portnoy, President and Chief Executive Officer; Jennifer B. Clark, Executive Vice President and General Counsel; David J. Hegarty, Executive Vice President and Secretary; Mark L. Kleifges, Executive Vice President; Bruce J. Mackey Jr., Executive Vice President; John A. Mannix, Executive Vice President; John G. Murray, Executive Vice President; Thomas M. O'Brien, Executive Vice President; John C. Popeo, Executive Vice President, Treasurer and Chief Financial Officer; David M. Blackman, Senior Vice President; Ethan S. Bornstein, Senior Vice President; Richard A. Doyle, Senior Vice President; Paul V. Hoagland, Senior Vice President; Vern D. Larkin, Senior Vice President; David M. Lepore, Senior Vice President; Andrew J. Rebholz, Senior Vice President; and Mark Young, Senior Vice President. Adam D. Portnoy, David M. Lepore and John C. Popeo are also our executive officers, and John A. Mannix was our President and Chief Operating Officer until January 2011. Other executive officers of RMR also serve as officers of other companies to which RMR provides management services.

        Employees.    We have no employees. Services which would be provided by employees are provided by RMR and by our Managing Trustees and officers. As of February 22, 2012, RMR had approximately 740 full time employees, including a headquarters staff and regional offices and personnel located throughout the United States.

        Select Income REIT.    On December 22, 2011, our wholly owned subsidiary, Select Income REIT, or SIR, filed a registration statement with the Securities and Exchange Commission, or the SEC, for an initial public offering, or IPO, of common shares as a REIT that is focused on owning and investing in net leased, single tenant properties. If the SIR registration statement becomes effective and the IPO is completed, we expect to continue to own a majority of SIR's common shares after the completion of the offering and because of our retained majority interest in SIR, we expect SIR will remain one of our consolidated subsidiaries. On February 16, 2012, we transferred 251 properties (approximately 21.4 million rentable square feet) to SIR, including substantially all of our commercial and industrial properties located in Oahu, HI and 23 suburban office and industrial properties located throughout the mainland U.S. In exchange for our contribution of 251 properties to SIR, we received 22.0 million SIR common shares and a $400.0 million demand promissory note, or the Demand Note. We expect that SIR would use net proceeds of its proposed IPO to repay in part amounts outstanding under the Demand Note. Upon completion of the IPO, SIR expects to enter into a $500.0 million bank facility

3


Table of Contents

with a group of commercial banks. Upon completion of the IPO, SIR intends to borrow under the bank facility to repay the balance of the Demand Note and reimburse us for the costs we incurred in organizing SIR, establishing its bank facility and preparing for its IPO. There can be no assurance that SIR will be successful in completing its share offering and establishing the bank facility or that it will have the funds to repay the Demand Note or to reimburse us for the costs we incurred in organizing SIR.

        In order to govern the separation of SIR from us, upon completion of the IPO, we intend to enter into a transaction agreement with SIR. We expect that the transaction agreement will provide, among other things, that (1) the current assets and liabilities of the properties to be transferred to SIR will, as of the time of the closing of the IPO of SIR's common shares, be settled between us and SIR so that we will retain all pre-closing current assets and liabilities and SIR will assume all post-closing current assets and liabilities and (2) SIR will indemnify us with respect to any liability relating to any property transferred to it by us, including any liability which relates to periods prior to SIR's formation.

        Our two Managing Trustees, Mr. Barry Portnoy and Mr. Adam Portnoy, are also trustees of SIR, and Mr. John Popeo, our Treasurer and Chief Financial Officer, also serves as the Treasurer and Chief Financial Officer of SIR. In addition, if the IPO is completed, it is currently expected that Mr. William Lamkin, one of our Independent Trustees, will serve as an independent trustee of SIR.

        If the SIR IPO is completed, we also expect that RMR will provide business and property management services to SIR. We expect that SIR will enter into management agreements with RMR which are on terms that are substantially similar to our management agreements with RMR. Accordingly, our management fees to RMR may be reduced by the amount of the management fees that would have otherwise been payable by us with respect to properties contributed by us to SIR. The SIR IPO will not occur unless, among other things, the SEC has declared the registration statement to be effective and underwriters have agreed to purchase and distribute the shares proposed to be offered by SIR. In addition, we may determine in our discretion, due to market conditions or otherwise, not to proceed with the SIR IPO. Accordingly, there can be no assurance that the IPO will occur.

        Competition.    Investing in and operating office and industrial real estate is a highly competitive business. We compete against other REITs, numerous financial institutions, individuals and public and private companies who are actively engaged in this business. Also, we compete for tenants and investments based on a number of factors including pricing, underwriting criteria and reputation. Our ability to successfully compete is also impacted by economic and population trends, availability of acceptable investment opportunities, our ability to negotiate beneficial leasing and investment terms, availability and cost of capital and new and existing laws and regulations. We do not believe we have a dominant position in any of the geographic markets in which we operate, but some of our competitors are dominant in selected markets. Many of our competitors have greater financial and other resources than we have. We believe the geographic diversity of our investments, the experience and abilities of our management, the quality of our assets and the financial strength of many of our tenants affords us some competitive advantages which have and will allow us to operate our business successfully despite the competitive nature of our business.

        For additional information on competition and the risks associated with our business, please see "Risk Factors" of this Annual Report on Form 10-K.

        Environmental and Climate Change Matters.    Under various laws, owners as well as tenants and operators of real estate may be required to investigate and clean up or remove hazardous substances present at or migrating from properties they own, lease or operate and may be held liable for property damage or personal injuries that result from hazardous substances. These laws also expose us to the possibility that we may become liable to reimburse governments for damages and costs they incur in connection with hazardous substances. We estimate the cost to remove hazardous substances at some of our properties based in part on environmental surveys of the properties we own prior to their purchase

4


Table of Contents

and we considered those costs when determining an acceptable purchase price. Estimated liabilities related to hazardous substances at properties we own are reflected in our consolidated balance sheets and included in the cost of the real estate acquired.

        Some of our industrial lands in Oahu, HI have been historically used for environmentally dangerous purposes and we do not have any insurance designated to limit losses at these properties that we may incur as a result of known or unknown environmental conditions which are not caused by an insured event, such as, for example, fire or flood. As of December 31, 2011, we have reserved approximately $12.2 million for environmental liabilities for our industrial lands in Oahu, HI. The environmental reserve we have applied to our industrial lands in Oahu, HI historically has not varied significantly from year to year and the actual historical costs to remediate certain environmental issues have not deviated significantly from the corresponding reserve amount. Nevertheless, we may have to engage in potentially expensive environmental clean up at these properties in the future, especially if we change the use of these properties.

        Certain of our buildings contain asbestos. We believe any asbestos in our buildings is contained in accordance with current regulations, and we have no current plans to remove any asbestos other than at one building in Monroeville, PA where we are renovating the property for new tenants. If we remove the asbestos or renovate or demolish these properties, certain environmental regulations govern the manner in which the asbestos must be handled and removed.

        We do not believe that there are environmental conditions at any of our properties that have had or will have a material adverse effect on us. However, no assurances can be given that conditions are not present at our properties or that costs we may be required to incur in the future to remediate contamination will not have a material adverse effect on our business or financial condition.

        The current political debate about climate change has resulted in various treaties, laws and regulations which are intended to limit carbon emissions. We believe these laws being enacted or proposed may cause energy costs at our properties to increase, but we do not expect the direct impact of these increases to be material to our results of operations because the increased costs either would be the responsibility of our tenants directly or in large part may be passed through by us to our tenants as additional lease payments. Although we do not believe it is likely in the foreseeable future, laws enacted to mitigate climate change may make some of our buildings obsolete or cause us to make material investments in our properties which could materially and adversely affect our financial condition. For more information, see "Risk Factors—Risks Related to Our Business—Acquisition and ownership of real estate is subject to environmental and climate change risks."

FEDERAL INCOME TAX CONSIDERATIONS

        The following summary of federal income tax considerations is based on existing law, and is limited to investors who own our shares as investment assets rather than as inventory or as property used in a trade or business. The summary does not discuss all of the particular tax consequences that might be relevant to you if you are subject to special rules under federal income tax law, for example if you are:

        The sections of the Internal Revenue Code of 1986, as amended, or the IRC, that govern federal income tax qualification and treatment of a REIT and its shareholders are complex. This presentation is a summary of applicable IRC provisions, related rules and regulations and administrative and judicial interpretations, all of which are subject to change, possibly with retroactive effect. Future legislative, judicial, or administrative actions or decisions could also affect the accuracy of statements made in this summary. We have not received a ruling from the Internal Revenue Service, or the IRS, with respect to any matter described in this summary, and we cannot assure you that the IRS or a court will agree with the statements made in this summary. The IRS or a court could, for example, take a different position from that described in this summary with respect to our acquisitions, operations, restructurings or other matters, which, if successful, could result in significant tax liabilities for applicable parties. In addition, this summary is not exhaustive of all possible tax consequences, and does not discuss any estate, gift, state, local, or foreign tax consequences. For all these reasons, we urge you and any prospective acquiror of our shares to consult with a tax advisor about the federal income tax and other tax consequences of the acquisition, ownership and disposition of our shares. Our intentions and beliefs described in this summary are based upon our understanding of applicable laws and regulations that are in effect as of the date of this Annual Report on Form 10-K. If new laws or regulations are enacted which impact us directly or indirectly, we may change our intentions or beliefs.

        Your federal income tax consequences may differ depending on whether or not you are a "U.S. shareholder." For purposes of this summary, a "U.S. shareholder" is:

6


Table of Contents

whose status as a U.S. shareholder is not overridden by an applicable tax treaty. Conversely, a "non-U.S. shareholder" is a beneficial owner of our shares who is not a U.S. shareholder. If a partnership (including any entity treated as a partnership for federal income tax purposes) is a beneficial owner of our shares, the tax treatment of a partner in the partnership generally will depend upon the status of the partner and the activities of the partnership. A beneficial owner that is a partnership and partners in such a partnership should consult their tax advisors about the federal income tax consequences of the acquisition, ownership and disposition of our shares.

Taxation as a REIT

        We have elected to be taxed as a REIT under Sections 856 through 860 of the IRC, commencing with our taxable year ending December 31, 1987. Our REIT election, assuming continuing compliance with the then applicable qualification tests, continues in effect for subsequent taxable years. Although no assurance can be given, we believe that we have been organized and have operated, and will continue to be organized and to operate, in a manner that qualified and will continue to qualify us to be taxed under the IRC as a REIT.

        As a REIT, we generally are not subject to federal income tax on our net income distributed as dividends to our shareholders. Distributions to our shareholders generally are included in their income as dividends to the extent of our current or accumulated earnings and profits. Our dividends are not generally entitled to the favorable 15% rate on qualified dividend income (scheduled to increase to ordinary income rates for taxable years beginning after December 31, 2012), but a portion of our dividends may be treated as capital gain dividends, all as explained below. No portion of any of our dividends is eligible for the dividends received deduction for corporate shareholders. Distributions in excess of current or accumulated earnings and profits generally are treated for federal income tax purposes as returns of capital to the extent of a recipient shareholder's basis in our shares, and will reduce this basis. Our current or accumulated earnings and profits are generally allocated first to distributions made on our preferred shares, and thereafter to distributions made on our common shares. For all these purposes, our distributions include both cash distributions and any in kind distributions of property that we might make.

        The conversion formula of our series D cumulative convertible preferred shares and our series E cumulative redeemable preferred shares may be adjusted under a number of circumstances; adjustments may include changes in the type or amount of consideration a shareholder receives upon conversion. Section 305 of the IRC treats some of these adjustments as constructive distributions, in which case they would be taxable in a similar manner to actual distributions. In general, a shareholder that holds our series D cumulative convertible preferred shares or our series E cumulative redeemable preferred shares would be deemed to receive a constructive distribution if the conversion price is adjusted for a taxable distribution to the holders of common shares. Such a shareholder's adjusted tax basis in, as applicable, series D cumulative convertible preferred shares or series E cumulative redeemable preferred shares would be increased by constructive distributions that are taxable as dividends or gain, and would be unaffected by constructive distributions that are nontaxable returns of capital. Conversely, a failure to appropriately adjust the conversion price of, as applicable, the series D cumulative convertible preferred shares or series E cumulative redeemable preferred shares could result in a constructive distribution to shareholders that hold our common shares, which would be taxable to them in a similar manner as actual distributions. A shareholder may also receive a constructive distribution if a conversion of its series D cumulative convertible preferred shares or its series E cumulative redeemable preferred shares is accompanied by a change in the conversion formula.

        If a shareholder actually or constructively owns none or a small percentage of our common shares, and such shareholder surrenders its preferred shares to us to be repurchased for cash only, then the repurchase of the preferred shares is likely to qualify for sale or exchange treatment because the repurchase would not be "essentially equivalent to a dividend" as defined by the IRC. More specifically, a cash repurchase of preferred shares will be treated under Section 302 of the IRC as a distribution, and hence taxable as a dividend to the extent of our allocable current or accumulated earnings and profits, as discussed above, unless the repurchase satisfies one of the tests set forth in Section 302(b) of the IRC and is therefore treated as a sale or exchange of the repurchased shares. The repurchase will be treated as a sale or exchange if it (1) is "substantially disproportionate" with respect to the surrendering shareholder's ownership in us, (2) results in a "complete termination" of the surrendering shareholder's common and preferred share interest in us, or (3) is "not essentially equivalent to a dividend" with respect to the surrendering shareholder, all within the meaning of Section 302(b) of the IRC. In determining whether any of these tests have been met, a shareholder must generally take into account our common and preferred shares considered to be owned by such shareholder by reason of constructive ownership rules set forth in the IRC, as well as our common and preferred shares actually owned by such shareholder. In addition, if a repurchase is treated as a distribution under the preceding tests, then a shareholder's tax basis in the repurchased preferred shares generally will be transferred to the shareholder's remaining shares of our common or preferred shares, if any, and if such shareholder owns no other shares of our common or preferred shares, such basis generally may be transferred to a related person or may be lost entirely. Because the determination as to whether a shareholder will satisfy any of the tests of Section 302(b) of the IRC depends upon the facts and circumstances at the time that the preferred shares are repurchased, we encourage you to consult your own tax advisor to determine your particular tax treatment.

        Our counsel, Sullivan & Worcester LLP, has opined that we have been organized and have qualified as a REIT under the IRC for our 1987 through 2011 taxable years, and that our current investments and plan of operation enable us to continue to meet the requirements for qualification and taxation as a REIT under the IRC. Our continued qualification and taxation as a REIT will depend upon our compliance with various qualification tests imposed under the IRC and summarized below. While we believe that we will satisfy these tests, our counsel does not review compliance with these tests on a continuing basis. If we fail to qualify as a REIT, we will be subject to federal income taxation as if we were a C corporation and our shareholders will be taxed like shareholders of C corporations. In this event, we could be subject to significant tax liabilities, and the amount of cash available for distribution to our shareholders could be reduced or eliminated.

        If we qualify as a REIT and meet the tests described below, we generally will not pay federal income tax on amounts we distribute to our shareholders. However, even if we qualify as a REIT, we may be subject to federal tax in the following circumstances:

Table of Contents

        If we fail to qualify or elect not to qualify as a REIT, we will be subject to federal income tax in the same manner as a C corporation. Distributions to our shareholders if we do not qualify as a REIT will not be deductible by us nor will distributions be required under the IRC. In that event, distributions to our shareholders will generally be taxable as ordinary dividends potentially eligible for the 15% income tax rate (scheduled to increase to ordinary income rates for taxable years beginning after December 31, 2012) discussed below in "Taxation of U.S. Shareholders" and, subject to limitations

Table of Contents

in the IRC, will be eligible for the dividends received deduction for corporate shareholders. Also, we will generally be disqualified from qualification as a REIT for the four taxable years following disqualification. Our failure to qualify as a REIT for even one year could result in reduction or elimination of distributions to our shareholders, or in our incurring substantial indebtedness or liquidating substantial investments in order to pay the resulting corporate-level taxes. The IRC provides certain relief provisions under which we might avoid automatically ceasing to be a REIT for failure to meet certain REIT requirements, all as discussed in more detail below.

REIT Qualification Requirements

        General Requirements.    Section 856(a) of the IRC defines a REIT as a corporation, trust or association:

Section 856(b) of the IRC provides that conditions (1) through (4) must be met during the entire taxable year and that condition (5) must be met during at least 335 days of a taxable year of 12 months, or during a pro rata part of a taxable year of less than 12 months. Section 856(h)(2) of the IRC provides that neither condition (5) nor (6) need be met for our first taxable year as a REIT. We believe that we have met conditions (1) through (7) during each of the requisite periods ending on or before the close of our most recently completed taxable year, and that we can continue to meet these conditions in future taxable years. There can, however, be no assurance in this regard.

        By reason of condition (6), we will fail to qualify as a REIT for a taxable year if at any time during the last half of a year more than 50% in value of our outstanding shares is owned directly or indirectly by five or fewer individuals. To help comply with condition (6), our declaration of trust and bylaws restrict transfers of our shares that would otherwise result in concentrated ownership positions. In addition, if we comply with applicable Treasury regulations to ascertain the ownership of our shares and do not know, or by exercising reasonable diligence would not have known, that we failed condition (6), then we will be treated as having met condition (6). However, our failure to comply with these regulations for ascertaining ownership may result in a penalty of $25,000, or $50,000 for intentional violations. Accordingly, we have complied and will continue to comply with these regulations, including requesting annually from record holders of significant percentages of our shares information regarding the ownership of our shares. Under our declaration of trust and bylaws, our shareholders are required to respond to these requests for information.

        For purposes of condition (6), the term "individuals" is defined in the IRC to include natural persons, supplemental unemployment compensation benefit plans, private foundations and portions of a trust permanently set aside or used exclusively for charitable purposes, but not other entities or qualified pension plans or profit-sharing trusts. As a result, REIT shares owned by an entity that is not an "individual" are considered to be owned by the direct and indirect owners of the entity that are

10


Table of Contents

individuals (as so defined), rather than to be owned by the entity itself. Similarly, REIT shares held by a qualified pension plan or profit-sharing trust are treated as held directly by the individual beneficiaries in proportion to their actuarial interests in such plan or trust. Consequently, five or fewer such trusts could own more than 50% of the interests in an entity without jeopardizing that entity's federal income tax qualification as a REIT. However, as discussed below, if a REIT is a "pension-held REIT," each qualified pension plan or profit-sharing pension trust owning more than 10% of the REIT's shares by value generally may be taxed on a portion of the dividends it receives from the REIT.

        The IRC provides that we will not automatically fail to be a REIT if we do not meet conditions (1) through (6), provided we can establish reasonable cause for any such failure. Each such excused failure will result in the imposition of a $50,000 penalty instead of REIT disqualification. It is impossible to state whether in all circumstances we would be entitled to the benefit of this relief provision. This relief provision applies to any failure of the applicable conditions, even if the failure first occurred in a prior taxable year.

        Our Wholly Owned Subsidiaries and Our Investments through Partnerships.    Except in respect of taxable REIT subsidiaries as discussed below, Section 856(i) of the IRC provides that any corporation, 100% of whose stock is held by a REIT and its disregarded subsidiaries, is a qualified REIT subsidiary and shall not be treated as a separate corporation. The assets, liabilities and items of income, deduction and credit of a qualified REIT subsidiary are treated as the REIT's. We believe that each of our direct and indirect wholly owned subsidiaries, other than the taxable REIT subsidiaries discussed below, will be either a qualified REIT subsidiary within the meaning of Section 856(i) of the IRC, or a noncorporate entity that for federal income tax purposes is not treated as separate from its owner under regulations issued under Section 7701 of the IRC. Thus, except for the taxable REIT subsidiaries discussed below, in applying all the federal income tax REIT qualification requirements described in this summary, all assets, liabilities and items of income, deduction and credit of our direct and indirect wholly owned subsidiaries are treated as ours.

        We have invested and may invest in real estate both through one or more entities that are treated as partnerships for federal income tax purposes, including limited or general partnerships, limited liability companies, or foreign entities. In the case of a REIT that is a partner in a partnership, regulations under the IRC provide that, for purposes of the REIT qualification requirements regarding income and assets discussed below, the REIT is deemed to own its proportionate share of the assets of the partnership corresponding to the REIT's proportionate capital interest in the partnership and is deemed to be entitled to the income of the partnership attributable to this proportionate share. In addition, for these purposes, the character of the assets and gross income of the partnership generally retain the same character in the hands of the REIT. Accordingly, our proportionate share of the assets, liabilities, and items of income of each partnership in which we are a partner is treated as ours for purposes of the income tests and asset tests discussed below. In contrast, for purposes of the distribution requirement discussed below, we must take into account as a partner our share of the partnership's income as determined under the general federal income tax rules governing partners and partnerships under Sections 701 through 777 of the IRC.

        Taxable REIT Subsidiaries.    We are permitted to own any or all of the securities of a "taxable REIT subsidiary" as defined in Section 856(l) of the IRC, provided that no more than 25% of the total value of our assets, at the close of each quarter, is comprised of our investments in the stock or securities of our taxable REIT subsidiaries. (For our 2001 through 2008 taxable years, no more than 20% of the total value of our assets, at the close of each quarter, was permitted to be comprised of our investments in the stock or securities of our taxable REIT subsidiaries; before the introduction of

11


Table of Contents

taxable REIT subsidiaries in 2001, our ability to own separately taxable corporate subsidiaries was more limited.) Among other requirements, a taxable REIT subsidiary of ours must:

        In addition, a corporation other than a REIT in which a taxable REIT subsidiary directly or indirectly owns more than 35% of the voting power or value will automatically be treated as a taxable REIT subsidiary. Subject to the discussion below, we believe that we and each of our taxable REIT subsidiaries have complied with, and will continue to comply with, on a continuous basis, the requirements for taxable REIT subsidiary status at all times during which we intend for the subsidiary's taxable REIT subsidiary election to be in effect, and we believe that the same will be true for any taxable REIT subsidiary that we later form or acquire.

        Our ownership of stock and securities in taxable REIT subsidiaries is exempt from the 10% and 5% REIT asset tests discussed below. Also, as discussed below, taxable REIT subsidiaries can perform services for our tenants without disqualifying the rents we receive from those tenants under the 75% or 95% gross income tests discussed below. Moreover, because taxable REIT subsidiaries are taxed as C corporations that are separate from us, their assets, liabilities and items of income, deduction and credit generally are not imputed to us for purposes of the REIT qualification requirements described in this summary. Therefore, taxable REIT subsidiaries can generally undertake third-party management and development activities and activities not related to real estate. Restrictions are imposed on taxable REIT subsidiaries to ensure that they will be subject to an appropriate level of federal income taxation. For example, a taxable REIT subsidiary may not deduct interest paid in any year to an affiliated REIT to the extent that the interest payments exceed, generally, 50% of the taxable REIT subsidiary's adjusted taxable income for that year. However, the taxable REIT subsidiary may carry forward the disallowed interest expense to a succeeding year, and deduct the interest in that later year subject to that year's 50% adjusted taxable income limitation. In addition, if a taxable REIT subsidiary pays interest, rent, or other amounts to its affiliated REIT in an amount that exceeds what an unrelated third party would have paid in an arm's length transaction, then the REIT generally will be subject to an excise tax equal to 100% of the excessive portion of the payment. Finally, if in comparison to an arm's length transaction, a tenant has overpaid rent to the REIT in exchange for underpaying the taxable REIT subsidiary for services rendered, and if the REIT has not adequately compensated the taxable REIT subsidiary for services provided to or on behalf of a tenant, then the REIT may be subject to an excise tax equal to 100% of the undercompensation to the taxable REIT subsidiary. There can be no assurance that arrangements involving our taxable REIT subsidiaries will not result in the imposition of one or more of these deduction limitations or excise taxes, but we do not believe that we are or will be subject to these impositions.

        Income Tests.    There are two gross income requirements for qualification as a REIT under the IRC:

12


Table of Contents

For purposes of the 75% and 95% gross income tests outlined above, income derived from a "shared appreciation provision" in a mortgage loan is generally treated as gain recognized on the sale of the property to which it relates. Although we will use our best efforts to ensure that the income generated by our investments will be of a type that satisfies both the 75% and 95% gross income tests, there can be no assurance in this regard.

        In order to qualify as "rents from real property" under Section 856 of the IRC, several requirements must be met:

13


Table of Contents

We believe that all or substantially all our rents have qualified and will qualify as rents from real property for purposes of Section 856 of the IRC.

        In order to qualify as mortgage interest on real property for purposes of the 75% test, interest must derive from a mortgage loan secured by real property with a fair market value, at the time the loan is made, at least equal to the amount of the loan. If the amount of the loan exceeds the fair market value of the real property, the interest will be treated as interest on a mortgage loan in a ratio equal to the ratio of the fair market value of the real property to the total amount of the mortgage loan.

        We have maintained, and will continue to maintain, appropriate books and records for our Australian properties in Australian dollars. Accordingly, for federal income tax purposes, including presumably the 75% and 95% gross income tests summarized above, our income, gains, and losses from our Australian operations will generally be calculated first in Australian dollars, and then translated into United States dollars at appropriate exchange rates. On the periodic repatriation of monies from our Australian operations to the United States, we will be required to recognize foreign exchange gains or losses; however, any foreign exchange gains we recognize from repatriation are expected to constitute "real estate foreign exchange gains" under Section 856(n)(2) of the IRC, and thus be excluded from the 75% and 95% gross income tests summarized above.

14


Table of Contents

        Absent the "foreclosure property" rules of Section 856(e) of the IRC, a REIT's receipt of business operating income from a property would not qualify under the 75% and 95% gross income tests. But as foreclosure property, gross income from such a business operation would so qualify. In the case of property leased by a REIT to a tenant, foreclosure property is defined under applicable Treasury regulations to include generally the real property and incidental personal property that the REIT reduces to possession upon a default or imminent default under the lease by the tenant, and as to which a foreclosure property election is made by attaching an appropriate statement to the REIT's federal income tax return. Any gain that a REIT recognizes on the sale of foreclosure property held as inventory or primarily for sale to customers, plus any income it receives from foreclosure property that would not qualify under the 75% gross income test in the absence of foreclosure property treatment, reduced by expenses directly connected with the production of those items of income, would be subject to income tax at the maximum corporate rate, currently 35%, under the foreclosure property income tax rules of Section 857(b)(4) of the IRC. Thus, if a REIT should lease foreclosure property in exchange for rent that qualifies as "rents from real property" as described above, then that rental income is not subject to the foreclosure property income tax.

        Other than sales of foreclosure property, any gain we realize on the sale of property held as inventory or other property held primarily for sale to customers in the ordinary course of business will be treated as income from a prohibited transaction that is subject to a penalty tax at a 100% rate. This prohibited transaction income also may adversely affect our ability to satisfy the 75% and 95% gross income tests for federal income tax qualification as a REIT. We cannot provide assurances as to whether or not the IRS might successfully assert that one or more of our dispositions is subject to the 100% penalty tax. However, we believe that dispositions of assets that we have made or that we might make in the future will not be subject to the 100% penalty tax, because we intend to:

        If we fail to satisfy one or both of the 75% or the 95% gross income tests in any taxable year, we may nevertheless qualify as a REIT for that year if we satisfy the following requirements:

It is impossible to state whether in all circumstances we would be entitled to the benefit of this relief provision for the 75% and 95% gross income tests. Even if this relief provision does apply, a 100% tax is imposed upon the greater of the amount by which we failed the 75% test or the 95% test, with adjustments, multiplied by a fraction intended to reflect our profitability. This relief provision applies to any failure of the applicable income tests, even if the failure first occurred in a year prior to the taxable year in which the failure was discovered.

        Asset Tests.    At the close of each quarter of each taxable year, we must also satisfy the following asset percentage tests in order to qualify as a REIT for federal income tax purposes:

15


Table of Contents

        When a failure to satisfy the above asset tests results from an acquisition of securities or other property during a quarter, the failure can be cured by disposition of sufficient nonqualifying assets within 30 days after the close of that quarter.

        In addition, if we fail the 5% value test or the 10% vote or value tests at the close of any quarter and do not cure such failure within 30 days after the close of that quarter, that failure will nevertheless be excused if (a) the failure is de minimis and (b) within 6 months after the last day of the quarter in which we identify the failure, we either dispose of the assets causing the failure or otherwise satisfy the 5% value and 10% vote and value asset tests. For purposes of this relief provision, the failure will be "de minimis" if the value of the assets causing the failure does not exceed the lesser of (a) 1% of the total value of our assets at the end of the relevant quarter or (b) $10,000,000. If our failure is not de minimis, or if any of the other REIT asset tests have been violated, we may nevertheless qualify as a REIT if (a) we provide the IRS with a description of each asset causing the failure, (b) the failure was due to reasonable cause and not willful neglect, (c) we pay a tax equal to the greater of (1) $50,000 or (2) the highest rate of corporate tax imposed (currently 35%) on the net income generated by the assets causing the failure during the period of the failure, and (d) within 6 months after the last day of the quarter in which we identify the failure, we either dispose of the assets causing the failure or otherwise satisfy all of the REIT asset tests. These relief provisions apply to any failure of the applicable asset tests, even if the failure first occurred in a year prior to the taxable year in which the failure was discovered.

        The IRC also provides an excepted securities safe harbor to the 10% value test that includes among other items (a) "straight debt" securities, (b) certain rental agreements in which payment is to be made in subsequent years, (c) any obligation to pay rents from real property, (d) securities issued by governmental entities that are not dependent in whole or in part on the profits of or payments from a nongovernmental entity, and (e) any security issued by another REIT.

        We have maintained and will continue to maintain records of the value of our assets to document our compliance with the above asset tests, and intend to take actions as may be required to cure any failure to satisfy the tests within 30 days after the close of any quarter.

        Annual Distribution Requirements.    In order to qualify for taxation as a REIT under the IRC, we are required to make annual distributions other than capital gain dividends to our shareholders in an amount at least equal to the excess of:

16


Table of Contents

The distributions must be paid in the taxable year to which they relate, or in the following taxable year if declared before we timely file our federal income tax return for the earlier taxable year and if paid on or before the first regular distribution payment after that declaration. If a dividend is declared in October, November, or December to shareholders of record during one of those months, and is paid during the following January, then for federal income tax purposes the dividend will be treated as having been both paid and received on December 31 of the prior taxable year. A distribution which is not pro rata within a class of our beneficial interests entitled to a distribution, or which is not consistent with the rights to distributions among our classes of beneficial interests, is a preferential distribution that is not taken into consideration for purposes of the distribution requirements, and accordingly the payment of a preferential distribution could affect our ability to meet the distribution requirements. Taking into account our distribution policies, including the dividend reinvestment plan we have adopted, we do not believe that we have made or will make any preferential distributions. The distribution requirements may be waived by the IRS if a REIT establishes that it failed to meet them by reason of distributions previously made to meet the requirements of the 4% excise tax discussed below. To the extent that we do not distribute all of our net capital gain and all of our real estate investment trust taxable income, as adjusted, we will be subject to federal income tax on undistributed amounts.

        In addition, we will be subject to a 4% nondeductible excise tax to the extent we fail within a calendar year to make required distributions to our shareholders of 85% of our ordinary income and 95% of our capital gain net income plus the excess, if any, of the "grossed up required distribution" for the preceding calendar year over the amount treated as distributed for that preceding calendar year. For this purpose, the term "grossed up required distribution" for any calendar year is the sum of our taxable income for the calendar year without regard to the deduction for dividends paid and all amounts from earlier years that are not treated as having been distributed under the provision. We will be treated as having sufficient earnings and profits to treat as a dividend any distribution by us up to the amount required to be distributed in order to avoid imposition of the 4% excise tax.

        If we do not have enough cash or other liquid assets to meet the 90% distribution requirements, we may find it necessary and desirable to arrange for new debt or equity financing to provide funds for required distributions in order to maintain our REIT status. We can provide no assurance that financing would be available for these purposes on favorable terms.

        We may be able to rectify a failure to pay sufficient dividends for any year by paying "deficiency dividends" to shareholders in a later year. These deficiency dividends may be included in our deduction for dividends paid for the earlier year, but an interest charge would be imposed upon us for the delay in distribution.

        In addition to the other distribution requirements above, to preserve our status as a REIT we are required to timely distribute C corporation earnings and profits that we inherit from acquired corporations.

Our Relationship with GOV

        Our formation of GOV, followed by GOV's issuance of its shares to the public in its IPO impacted our own REIT qualification and taxation under the IRC in the following manner.

        Formation of GOV.    Prior to its IPO, GOV and its wholly owned subsidiaries were wholly owned by us. During this period, GOV and its subsidiaries were disregarded as entities separate from us for federal income tax purposes, either under the regulations issued under Section 7701 of the IRC or under the qualified REIT subsidiary rules of Section 856(i), all as described above. Accordingly, all assets, liabilities and items of income, deduction and credit of GOV and its subsidiaries during this period, including in particular the outstanding indebtedness on the GOV credit facility, were treated as ours. Under the transaction agreement we entered into with GOV at the time of GOV's IPO, or the

17


Table of Contents

GOV transaction agreement, the federal income tax liabilities and federal income tax filings for GOV and its subsidiaries for this period are our responsibility.

        Our Taxation upon GOV's IPO.    When GOV first issued shares to persons other than us, or the GOV Effective Time, GOV ceased to be wholly owned by us. As a consequence, GOV and its subsidiaries ceased to be our disregarded entities for federal income tax purposes. Instead, at that time, GOV became regarded as a separate corporation that we believe satisfied the requirements for qualification and taxation as a REIT under the IRC, and its subsidiaries ceased to be treated as part of us and became disregarded entities treated as part of the newly separate GOV. In particular, there was a "Deemed Exchange" for federal income tax purposes at the time when GOV ceased to be wholly owned by us, and this Deemed Exchange encompassed the following features:

For the Deemed Exchange to have been nontaxable to us for federal income tax purposes (except up to the extent of the approximately $6 million reimbursement obligation to us from GOV), each of the three issues discussed below must be concluded upon favorably. Based on representations from us and from GOV, our tax counsel, Sullivan & Worcester LLP, opined that the Deemed Exchange should be governed by Sections 351(a) and 357(a) of the IRC, except for up to approximately $6 million of gain recognized by us under Section 351(b) of the IRC in respect of GOV's obligation to reimburse us for specified amounts that we advanced to GOV, all for the reasons discussed below.

        First, Section 351(e) of the IRC must not have applied to the Deemed Exchange, or else it would have disqualified the Deemed Exchange from Sections 351(a) and 351(b) treatment altogether. Section 351(e) and applicable regulations provide that, if our contribution of assets to GOV in the Deemed Exchange resulted, directly or indirectly, in diversification for us, then Sections 351(a) and 351(b) would not apply to the Deemed Exchange. Because we believe GOV was a REIT beginning with its taxable year that commenced at the GOV Effective Time and because the public was viewed as having contributed cash to GOV in the Deemed Exchange, our contribution of assets to GOV in the Deemed Exchange was automatically treated as resulting in diversification for us unless the assets we contributed to GOV in the Deemed Exchange were already a diversified portfolio. That is, if the GOV portfolio was already a diversified portfolio, then the Deemed Exchange did not result in diversification for us, and thus Section 351(e) did not apply. Regulations under Section 351(e) provide a diversification standard for investment securities, including a provision that treats federal government securities as automatically diversified; but these regulations do not provide a diversification standard for real estate. Still, the IRS has over the years issued several private letter rulings on diversified real estate portfolios, in each instance concluding that the real estate portfolio in question was a diversified portfolio and thus that Section 351(e) was inapplicable. These private letter rulings do not consistently cite the same diversification factors, but cumulatively they reference similar factors such as geographic diversity, tenant diversity, lease length diversity and asset type diversity. Although private letter rulings

18


Table of Contents

are not precedential and cannot be relied upon by taxpayers other than the ones to whom they are addressed, they do provide insight into how the IRS interprets and applies the federal income tax law.

        We believe that the GOV real estate portfolio at the GOV Effective Time was diversified for Section 351(e) purposes, given the properties' diversity in geography, size, age, operating history and remaining lease length. We believe that having the federal government as the principal tenant in most of the GOV portfolio did not detract from the diversified nature of these properties for several reasons, including:

Based on the above analysis, we believe that Section 351(e) did not apply to the Deemed Exchange.

        Second, Section 357(a) provides that liabilities assumed by a transferee from a transferor, in connection with a transfer of assets from the transferor to the transferee governed by Sections 351(a) and 351(b), will not be taxable consideration to the transferor. However, Section 357(b) provides that Section 357(a) will not apply, and thus all assumed liabilities will constitute taxable consideration (up to the amount of actual realized gains), if any liability assumption in the transaction was made either with a purpose to avoid federal income tax or without a bona fide business purpose. In Revenue Ruling 79-258, 1979-2 C.B. 143, and in several subsequent private letter rulings, the IRS applied Sections 357(a) and 357(b) to conclude that a proportional part of the total debt of a parent corporation can be allocated to the properties and assets contributed to a new subsidiary and that this proportional part can be assigned to and assumed by the subsidiary as follows: the subsidiary may assume a new debt, the loan proceeds of which are used by the parent to pay down the parent's other, older debt. In effect, the new debt is successor indebtedness of the parent which has been proportionately assigned to and assumed by the subsidiary. We and GOV attempted to structure the Deemed Exchange so as to come within the principles articulated in these published and private rulings, and we believe that we did so. For example, based on our computations, in the Deemed Exchange we and GOV believe that we allocated, and therefore that GOV assumed in the form of the GOV credit facility and GOV's other liabilities, no more than a proportional part of our overall indebtedness prior to the Deemed Exchange. Accordingly, we believe that GOV's assumption of liabilities from us in the Deemed Exchange was nontaxable consideration to us under Section 357(a) of the IRC.

        Third, related to but perhaps distinct from the preceding issue under Sections 357(a) and 357(b) of the IRC, Waterman Steamship v. Commissioner, 430 F.2d 1185 (5th Cir. 1970), and subsequent tax cases apply a judicial recharacterization rule to pre-transaction dividends funded from newly borrowed proceeds. Under this case law, part or all of a pre-transaction dividend funded from a new borrowing is recharacterized as a taxable sale for cash, if the borrowing is paid off post-transaction with proceeds

19


Table of Contents

from cash investors, and if the new borrowing is temporary and supported by the impending cash investment. This case law, to the extent it was applicable to our transactions with GOV, would have overturned our nontaxable treatment of the debt-funded cash dividend paid by GOV to us prior to the Deemed Exchange, and instead would have recharacterized that cash flow as our cash sale of a portion of GOV to the new public shareholders of GOV, a characterization which would have rendered Sections 351(a) and 351(b) of the IRC inapplicable. For a number of reasons, we believe that this case law did not apply to our transactions with GOV, and thus that the Deemed Exchange was properly governed by Sections 351(a), 351(b) and 357(a) of the IRC. As discussed above, under the authority of Revenue Ruling 79-258, 1979-2 C.B. 143, and subsequent private letter rulings, the GOV credit facility and the dividend to us funded from that credit facility were not properly viewed as a new borrowing and associated dividend, but instead as the mechanism by which no more than a proportional amount of our overall debt was fairly assigned to and assumed by GOV. Further, the GOV credit facility and the associated dividend were put in place and completed before the outcome of GOV's IPO was known. In our view, this timing not only demonstrates that the GOV credit facility and associated dividend were a separate, independent step from its IPO for federal income tax purposes, but also demonstrates that the lenders underwriting GOV's credit facility, which had a four-year term inclusive of renewal options, looked to the security of GOV's portfolio and revenues rather than the success of GOV's IPO. In addition, when the GOV credit facility was put in place, the amount of cash that might have been raised in a potential IPO was not known, and thus that cash amount could have been greater than or less than the amount outstanding on the GOV credit facility at the GOV Effective Time. Finally, the case law at issue involves pre-transaction dividends where the underlying transaction is already a sale of subsidiary stock between a seller and a buyer, typically for cash, and so the effect of the judicial recharacterization is merely to convert the subject dividend proceeds into additional sale proceeds. However, our transactions with GOV and the Deemed Exchange were different because there was no sale by us to the public of GOV shares included in the baseline set of transactions, and we thus believe it would have been improper to recharacterize a pre-transaction dividend as a sale in circumstances in which no sale is formally occurring.

        Consequences if Deemed Exchange Were Taxable.    Based on representations from us and from GOV, our tax counsel, Sullivan & Worcester LLP, opined that the Deemed Exchange should be governed by Sections 351(a) and 357(a) of the IRC, except for up to approximately $6 million of gain recognized by us under Section 351(b) of the IRC in respect of GOV's obligation to reimburse us for specified amounts that we advanced to GOV. However, upon review the IRS or a court might conclude otherwise. For example, contrary to Sullivan & Worcester LLP's opinion and our belief, the IRS or a court might take one or more of the following views: that the GOV portfolio was not a diversified portfolio for purposes of Section 351(e) of the IRC; that the assumption of liabilities by GOV from us in the Deemed Exchange was governed by Section 357(b) rather than Section 357(a) of the IRC; or that the debt-funded cash dividend paid by GOV to us was properly recharacterized as sale proceeds that preclude the application of Sections 351(a) and 351(b) of the IRC. If we were unsuccessful in challenging any such adverse determination, then we would recognize most or all of the taxable gain in the GOV portfolio, computed as discussed below. We expect that any taxable gain that we recognized or may be required to recognize, including the up to approximately $6 million of gain we recognized under Section 351(b), would be treated as capital gain, subject to ordinary income treatment for any depreciation recaptured under Sections 1245 and 1250 of the IRC.

        If the Deemed Exchange were not governed by Sections 351(a), 351(b) and 357(a), our recognized taxable gain in the GOV portfolio would generally have equaled our aggregate amount realized in the Deemed Exchange, minus our aggregate adjusted tax basis in the GOV portfolio immediately before the GOV Effective Time. Our aggregate amount realized in the Deemed Exchange equaled the sum of (1) the fair market value of the GOV shares that we owned immediately after the GOV Effective Time, (2) the liabilities that GOV was treated as assuming from us in the Deemed Exchange, and (3) the approximately $6 million reimbursement obligation from GOV to us. Employing the valuation

20


Table of Contents

methodologies described below, we estimate that, if contrary to our expectation we recognized significant gain as a result of the Deemed Exchange, then this taxable gain would have been approximately $85 million.

        In computing our aggregate amount realized, we were required to value for federal income tax purposes the GOV shares that we owned immediately after the GOV Effective Time. Under applicable judicial precedent, it is possible that the following two valuations may differ for federal income tax purposes: (1) the per share fair market value of the GOV shares that we owned immediately after the GOV Effective Time, versus (2) the average of the reported high and low trading prices for the GOV shares in the public market on the date of the GOV Effective Time (called the "GOV Initial Price"). Because of the factual nature of the value of GOV shares, Sullivan & Worcester LLP is unable to render an opinion on the valuation of GOV shares generally, or on the valuation of the GOV shares that we owned immediately after the GOV Effective Time. Nevertheless, we believe that the per share fair market value of any and all GOV shares at the GOV Effective Time was properly valued at the GOV Initial Price for federal income tax purposes. Accordingly, the GOV Initial Price will be used for all of our tax reporting, including for purposes of computing any gain we may have recognized in the Deemed Exchange.

        Prior to the Deemed Exchange, we held the assets comprising the GOV portfolio for investment with a view to long-term income production and capital appreciation, and the conversion of GOV into a separate REIT by means of its IPO represented a new, unique opportunity to realize the value of that investment. Accordingly, we believe that any gains we recognized in the GOV portfolio as a result of the Deemed Exchange, including in any event the up to approximately $6 million recognized as a result of Section 351(b), would not have been subject to the 100% penalty tax of Section 857(b)(6) of the IRC, described above, applicable to gains from the disposition of inventory or other property held primarily for sale to customers. Moreover, we believe that any such recognized gains from the Deemed Exchange qualified as gains from disposition of real property, and therefore counted favorably toward our compliance with the 75% and 95% gross income tests, as described above.

        If in a later year it is ultimately determined, contrary to our expectation, that we recognized additional gain or income as a result of the Deemed Exchange not qualifying under Sections 351(a), 351(b) or 357(a) of the IRC, then we may be required to amend our tax reports, including those sent to our shareholders, and we will owe federal income tax on the undistributed gain and income unless we elect to pay a sufficient deficiency dividend to our shareholders. As discussed above, deficiency dividends may be included in our deduction for dividends paid for the year in which such gain or income is recognized, but an interest charge would be imposed upon us for the delay in distribution.

        Our Investment in GOV.    Following the GOV Effective Time, we owned and continue to own a significant amount, in excess of 10%, of GOV shares. In general, our aggregate initial tax basis in these shares equaled our aggregate adjusted tax basis in the GOV portfolio immediately before the GOV Effective Time, minus the liabilities accrued for federal income tax purposes and assumed by GOV from us in the Deemed Exchange, plus any gain we recognized in the Deemed Exchange, minus the approximately $6 million reimbursement obligation received by us from GOV. As discussed above, we believe that we did not recognize, and our counsel Sullivan & Worcester LLP opined that we should not have recognized, any gain in the Deemed Exchange, except up to the extent of GOV's approximately $6 million reimbursement obligation to us.

        For any of our taxable years in which GOV qualifies as a REIT, our investment in GOV will count as a qualifying REIT asset toward the REIT gross asset tests and our gains and dividends from GOV shares will count as qualifying income under the 75% and 95% gross income tests, all as described above. However, because we cannot control GOV's compliance with the federal income tax requirements for REIT qualification and taxation, we joined with GOV in filing a protective taxable REIT subsidiary election under Section 856(l) of the IRC, effective June 9, 2009, and we have

21


Table of Contents

reaffirmed this protective election with GOV every January 1 thereafter, and may continue to do so, unless and until our ownership of GOV falls below 9.8%. Pursuant to this protective taxable REIT subsidiary election, we believe that even if GOV is not a REIT for some reason, then it would instead be considered one of our taxable REIT subsidiaries and treated in the manner described above. As one of our taxable REIT subsidiaries, we believe that GOV's failure to qualify as a REIT would not jeopardize our own qualification as a REIT even though we own more than 10% of it.

        As discussed above, the GOV transaction agreement contains provisions that require GOV and us, due to our ongoing affiliation, to refrain from taking actions that may jeopardize the other's qualifications as a REIT under the IRC. For example, each of us is obligated to limit its investment in any tenant of the other, so that neither owns more than 4.9% of any such tenant, and each of us is obligated to cooperate reasonably with the other's requests motivated by REIT qualification and taxation.

Our Relationship with SIR

        As discussed further above, on December 22, 2011, SIR, our wholly owned subsidiary, filed a registration statement with the SEC for a sale of SIR's common shares to the public in its IPO. If the SIR registration statement becomes effective and the IPO is completed, we expect to continue to own a majority of SIR's common shares after the completion of the offering. Our formation of SIR, followed by SIR's possible issuance of its common shares to the public in an IPO in the manner currently contemplated by us, would impact our own REIT qualification and taxation under the IRC in the manner described below. The proposed IPO may change or may not occur. There can be no assurance that SIR will be successful in completing a share offering and the related transactions described above.

        Formation of SIR.    While SIR and its wholly owned subsidiaries remain wholly owned by us, SIR and those subsidiaries are disregarded as entities separate from us for federal income tax purposes, either under the regulations issued under Section 7701 of the IRC or under the qualified REIT subsidiary rules of Section 856(i), all as described above. Accordingly, all assets, liabilities and items of income, deduction and credit of SIR and its subsidiaries during this period are treated as ours. Under the transaction agreement we expect to enter into with SIR at the time of SIR's IPO, or the expected SIR transaction agreement, the federal income tax liabilities and federal income tax filings for SIR and its subsidiaries for this period are our responsibility.

        Our Taxation if SIR's IPO Occurs.    To summarize the applicable federal income tax consequences to us of SIR's IPO, the following discussion assumes that SIR will successfully issue its shares to the public in an IPO in the manner currently contemplated, as more fully described above. Upon SIR first issuing shares to persons other than us, or the SIR Effective Time, SIR would cease to be wholly owned by us. As a consequence, SIR and its subsidiaries would cease to be our disregarded entities for federal income tax purposes. Instead, at that time, SIR would become regarded as a separate corporation that is expected to satisfy the requirements for qualification and taxation as a REIT under the IRC, and its subsidiaries would cease to be treated as part of us and become disregarded entities treated as part of the newly separate SIR. In particular, there would be a "Deemed Exchange" for federal income tax purposes at the time when SIR ceases to be wholly owned by us, and this Deemed Exchange would encompass the following features:

22


Table of Contents

        Based on representations from us and from SIR, our tax counsel, Sullivan & Worcester LLP, is expected to opine that, because the initial SIR portfolio of properties is sufficiently diversified in terms of tenants, size, age, operating history and remaining lease length, Section 351(e) of the IRC should not apply, and accordingly the Deemed Exchange should be governed by Sections 351 and 357 of the IRC, rather than Section 1001 of the IRC.

        However, because SIR's $400.0 million note and reimbursement obligations to us would be treated as nonqualifying consideration under Section 351(b) of the IRC, we would expect to recognize almost all of our realized tax gains from the Deemed Exchange whether Sections 351 and 357 apply or whether instead Section 1001 applies. Also, in either such case, because we expect to own more than 50% of SIR following its IPO, we expect most of our recognized tax gains to be ordinary gains pursuant to Section 1239 of the IRC.

        In computing our aggregate amount realized, we would be required to value for federal income tax purposes the SIR shares that we own immediately after the SIR Effective Time. Under applicable judicial precedent, it is possible that the following two valuations may differ for federal income tax purposes: (1) the per share fair market value of the SIR shares that we own immediately after the SIR Effective Time, versus (2) the average of the reported high and low trading prices for the SIR shares in the public market on the date of the SIR Effective Time (called the "SIR Initial Price"). Because of the factual nature of the value of SIR shares, Sullivan & Worcester LLP is unable to render an opinion on the valuation of SIR shares generally, or on the valuation of the SIR shares that we would continue to own immediately after the SIR Effective Time. Nevertheless, we believe that the per share fair market value of any and all SIR shares at the SIR Effective Time may be valued at the SIR Initial Price for federal income tax purposes. Accordingly, we intend to use the SIR Initial Price for all of our tax reporting, including for purposes of computing any gain we may recognize in the Deemed Exchange.

        Prior to the Deemed Exchange, we expect to hold the assets comprising the SIR portfolio for investment with a view to long-term income production and capital appreciation, and the conversion of SIR into a separate REIT by means of its IPO represented a new, unique opportunity to realize the value of that investment. Accordingly, we believe that any gains we may recognize in the SIR portfolio as a result of the Deemed Exchange will not be subject to the 100% penalty tax of Section 857(b)(6) of the IRC, described above, applicable to gains from the disposition of inventory or other property held primarily for sale to customers. Moreover, we believe that any such recognized gains from the Deemed Exchange would qualify as gains from disposition of real property, and therefore would count favorably toward our compliance with the 75% and 95% gross income tests, as described above.

        If in a later year it is ultimately determined, contrary to our expectation, that we recognized additional gain or income as a result of the Deemed Exchange, then we may be required to amend our tax reports, including those sent to our shareholders, and we would owe federal income tax on the undistributed gain and income unless we elect to pay a sufficient deficiency dividend to our shareholders. As discussed above, deficiency dividends may be included in our deduction for dividends paid for the year in which such gain or income is recognized, but an interest charge would be imposed upon us for the delay in distribution.

        Our Investment in SIR.    As discussed above, we expect to continue to own a majority of SIR's common shares after the completion of the IPO if it occurs. For any of our taxable years in which SIR qualifies as a REIT, our investment in SIR would count as a qualifying REIT asset toward the REIT gross asset tests and our gains and dividends from SIR shares would count as qualifying income under the 75% and 95% gross income tests, all as described above. However, because after its IPO we cannot necessarily control SIR's compliance with the federal income tax requirements for REIT qualification and taxation, we expect to join with SIR in filing a protective taxable REIT subsidiary election under Section 856(l) of the IRC, effective at the SIR Effective Time, and we may reaffirm this protective election with SIR every January 1 thereafter, unless and until our ownership of SIR falls below 9.8%. Pursuant to this protective taxable REIT subsidiary election, we believe that even if SIR is not a REIT for some reason, then it would instead be considered one of our taxable REIT subsidiaries and treated in the manner described above. As one of our taxable REIT subsidiaries, we believe that SIR's failure to qualify as a REIT would not jeopardize our own qualification as a REIT, even though we own more than 10% of it.

        As discussed above, the expected SIR transaction agreement is expected to contain provisions that require SIR and us, due to our ongoing affiliation, to refrain from taking actions that may jeopardize the other's qualifications as a REIT under the IRC.

Acquisition of C Corporations

        On July 17, 2008, we acquired a C corporation in a transaction where the C corporation was ultimately merged into our disregarded entity under Treasury regulations issued under Section 7701 of the IRC, all as described in Section 381(a) of the IRC. Thus, after the acquisition, all assets, liabilities and items of income, deduction and credit of the acquired corporation, and a proportionate share of the assets, liabilities and items of income, deduction and credit of the partnership in which the acquired corporation was a partner, have been treated as ours for purposes of the various REIT qualification tests described above. In addition, we generally were treated as the successor to the acquired corporate entity's federal income tax attributes, such as the entity's adjusted tax bases in its assets and its depreciation schedules; we were also treated as the successor to the acquired corporate entity's earnings and profits for federal income tax purposes.

        On October 7, 2010, we purchased office and industrial properties in Australia. In order to acquire the Australian properties, we acquired all of the beneficial interests of an Australian trust that owned those properties as its primary assets. Upon our acquisition, the acquired entity became either our qualified REIT subsidiary under Section 856(i) of the IRC or our disregarded entity (or, at a minimum, our almost wholly owned partnership) under Treasury regulations issued under Section 7701 of the IRC. Thus, after the 2010 acquisition, we have treated and will treat all assets, liabilities and items of income, deduction and credit of the acquired Australian trust as ours for purposes of the various REIT qualification tests described above. To address the possibility that the acquired trust was properly classified as a C corporation for federal tax purposes prior to our acquisition, we made an election under Section 338(g) of the IRC in respect of the acquired Australian trust. Accordingly, regardless of the Australian trust's proper federal tax classification prior to our acquisition, our initial federal income tax basis in the acquired assets is our cost for acquiring them, and we neither succeeded to any C corporation earnings and profits in this acquisition nor acquired any built-in gain in former C corporation assets.

        Built-in Gains from C Corporations.    As described above, notwithstanding our qualification and taxation as a REIT, we may still be subject to corporate taxation in particular circumstances. Specifically, if we acquire an asset from a corporation in a transaction in which our adjusted tax basis

24


Table of Contents

in the asset is determined by reference to the adjusted tax basis of that asset in the hands of a present or former C corporation, and if we subsequently recognize gain on the disposition of that asset during a specified period (generally, ten years) beginning on the date on which the asset ceased to be owned by the C corporation, then we will generally pay tax at the highest regular corporate tax rate, currently 35%, on the lesser of (1) the excess, if any, of the asset's fair market value over its adjusted tax basis, each determined as of the time the asset ceased to be owned by the C corporation, or (2) our gain recognized in the disposition. Accordingly, any taxable disposition of an asset so acquired during the specified period (generally, ten years) could be subject to tax under these rules. However, we have not disposed, and have no present plan or intent to dispose, of any material assets acquired in such transactions.

        To the extent of our gains in a taxable year that are subject to the built-in gains tax described above, net of any taxes paid on such gains with respect to that taxable year, our taxable dividends paid to you in the following year will be potentially eligible for treatment as qualified dividends that are taxed to our noncorporate U.S. shareholders at the maximum capital gain rate of 15% (scheduled to expire for taxable years beginning after December 31, 2012).

        Earnings and Profits.    A REIT may not have any undistributed C corporation earnings and profits at the end of any taxable year. Upon the closing of the July 17, 2008 transaction, we succeeded to the undistributed earnings and profits, if any, of the acquired corporate entity. Thus, we needed to distribute any such earnings and profits no later than the end of the applicable tax year. If we failed to do so, we would not qualify to be taxed as a REIT for that year and a number of years thereafter, unless we are able to rely on the relief provision described below.

        Although Sullivan & Worcester LLP is unable to render an opinion on factual determinations such as the amount of undistributed earnings and profits, we retained accountants to compute the amount of undistributed earnings and profits that we inherited in the July 17, 2008 transaction. Based on these calculations, we believe that we did not inherit any undistributed earnings and profits that remained undistributed at the end of the applicable tax year. However, there can be no assurance that the IRS would not, upon subsequent examination, propose adjustments to our calculation of the undistributed earnings and profits that we inherited, including adjustments that might be deemed necessary by the IRS as a result of its examination of the companies we acquired. In any such examination, the IRS might consider all taxable years of the acquired subsidiaries as open for review for purposes of its proposed adjustments. If it is subsequently determined that we had undistributed earnings and profits as of the end of the applicable tax year, we may be eligible for a relief provision similar to the "deficiency dividends" procedure described above. To utilize this relief provision, we would have to pay an interest charge for the delay in distributing the undistributed earnings and profits; in addition, we would be required to distribute to our shareholders, in addition to our other REIT distribution requirements, the amount of the undistributed earnings and profits less the interest charge paid.

Depreciation and Federal Income Tax Treatment of Leases

        Our initial tax bases in our assets will generally be our acquisition cost. We will generally depreciate our real property on a straight-line basis over 40 years and our personal property over the applicable shorter periods. These depreciation schedules may vary for properties that we acquire through tax-free or carryover basis acquisitions.

        We are entitled to depreciation deductions from our facilities only if we are treated for federal income tax purposes as the owner of the facilities. This means that the leases of the facilities must be classified for federal income tax purposes as true leases, rather than as sales or financing arrangements, and we believe this to be the case. In the case of sale-leaseback arrangements, the IRS could assert that we realized prepaid rental income in the year of purchase to the extent that the value of a leased property, at the time of purchase, exceeded the purchase price for that property. While we believe that

25


Table of Contents

the value of leased property at the time of purchase did not exceed purchase prices, because of the lack of clear precedent we cannot provide assurances as to whether the IRS might successfully assert the existence of prepaid rental income in any of our sale-leaseback transactions.

Like-Kind Exchanges

        In May 2008, we entered into a series of agreements to sell 48 medical office, clinic and biotech laboratory buildings to SNH; each of these properties was sold during 2008 or 2009 except for one, which is no longer subject to an agreement for sale. In June 2010, we entered into a series of agreements to sell 15 properties to GOV; each of these properties was sold during 2010. In November 2010, we entered into a series of agreements to sell 27 medical office, clinic and biotech laboratory buildings to SNH; each of these properties was sold during 2010 or 2011. On advice of counsel, we believe that each of the closings for our disposed properties should be viewed as a separate transaction for federal income tax purposes. We therefore entered into IRC Section 1031 like-kind exchanges for some, but not all, of the closings and reported those transactions as dispositions and exchanges separate from each other and from any cash sales.

        If, contrary to our view, the IRS recharacterizes our separate closings as one or more composite transactions, then some or all of our realized gain on the several dispositions that were intended to be like-kind exchanges may, contrary to our expectation of nonrecognition, be recognized in full. In that event, we may not have distributed all of our capital gain for 2008 through 2011, and we may owe federal income tax on the undistributed capital gain unless we elect to pay deficiency dividends to our shareholders. As discussed above, deficiency dividends may be included in our deduction for dividends paid for the year in which such gain is recognized, but an interest charge would be imposed upon us for the delay in distribution.

Taxation of U.S. Shareholders

        For noncorporate U.S. shareholders, the maximum federal income tax rate for long-term capital gains is generally 15% (scheduled to increase to 20% for taxable years beginning after December 31, 2012) and for most corporate dividends is generally also 15% (scheduled to increase to ordinary income rates for taxable years beginning after December 31, 2012). However, because we are not generally subject to federal income tax on the portion of our REIT taxable income or capital gains distributed to our shareholders, dividends on our shares generally are not eligible for such 15% tax rate on dividends while that rate is in effect. As a result, our ordinary dividends continue to be taxed at the higher federal income tax rates applicable to ordinary income. However, the favorable federal income tax rates for long-term capital gains, and while in effect, for dividends, generally apply to:

        As long as we qualify as a REIT for federal income tax purposes, a distribution to our U.S. shareholders (including any constructive distributions on our common shares, on our series D cumulative convertible preferred shares, or on our series E cumulative redeemable preferred shares) that we do not designate as a capital gain dividend will be treated as an ordinary income dividend to the extent of our current or accumulated earnings and profits. Distributions made out of our current or

26


Table of Contents

accumulated earnings and profits that we properly designate as capital gain dividends generally will be taxed as long-term capital gains, as discussed below, to the extent they do not exceed our actual net capital gain for the taxable year. However, corporate shareholders may be required to treat up to 20% of any capital gain dividend as ordinary income under Section 291 of the IRC.

        In addition, we may elect to retain net capital gain income and treat it as constructively distributed. In that case:

If we elect to retain our net capital gains in this fashion, we will notify our U.S. shareholders of the relevant tax information within 60 days after the close of the affected taxable year.

        As discussed above, for noncorporate U.S. shareholders, long-term capital gains are generally taxed at maximum rates of 15% (scheduled to increase to 20% for taxable years beginning after December 31, 2012) or 25%, depending upon the type of property disposed of and the previously claimed depreciation with respect to this property. If for any taxable year we designate capital gain dividends for U.S. shareholders, then a portion of the capital gain dividends we designate will be allocated to the holders of a particular class of shares on a percentage basis equal to the ratio of the amount of the total dividends paid or made available for the year to the holders of that class of shares to the total dividends paid or made available for the year to holders of all classes of our shares. We will similarly designate the portion of any capital gain dividend that is to be taxed to noncorporate U.S. shareholders at the maximum rates of 15% (scheduled to increase to 20% for taxable years beginning after December 31, 2012) or 25% so that the designations will be proportionate among all classes of our shares.

        Distributions in excess of current or accumulated earnings and profits will not be taxable to a U.S. shareholder to the extent that they do not exceed the shareholder's adjusted tax basis in the shareholder's shares, but will reduce the shareholder's basis in those shares. To the extent that these excess distributions exceed the adjusted basis of a U.S. shareholder's shares, they will be included in income as capital gain, with long-term gain generally taxed to noncorporate U.S. shareholders at a maximum rate of 15% (scheduled to increase to 20% for taxable years beginning after December 31, 2012). No U.S. shareholder may include on his federal income tax return any of our net operating losses or any of our capital losses.

        If a dividend is declared in October, November, or December to shareholders of record during one of those months, and is paid during the following January, then for federal income tax purposes the dividend will be treated as having been both paid and received on December 31 of the prior taxable year. Also, items that are treated differently for regular and alternative minimum tax purposes are to be allocated between a REIT and its shareholders under Treasury regulations which are to be prescribed. It is possible that these Treasury regulations will require tax preference items to be allocated to our shareholders with respect to any accelerated depreciation or other tax preference items that we claim.

27


Table of Contents

        A U.S. shareholder will generally recognize gain or loss equal to the difference between the amount realized and the shareholder's adjusted basis in our shares that are sold or exchanged. This gain or loss will be capital gain or loss, and will be long-term capital gain or loss if the shareholder's holding period in the shares exceeds one year. In addition, any loss upon a sale or exchange of our shares held for six months or less will generally be treated as a long-term capital loss to the extent of our long-term capital gain dividends during the holding period.

        In contrast to the typical redemption of preferred shares for cash only, discussed above, if a U.S. shareholder receives a number of our common shares as a result of a conversion or repurchase of series D cumulative convertible preferred shares or of series E cumulative redeemable preferred shares, then the transaction will be treated as a recapitalization. As such, the shareholder would recognize income or gain only to the extent of the lesser of (1) the excess, if any, of the value of the cash and common shares received over such shareholder's adjusted tax basis in, as applicable, its series D cumulative convertible preferred shares or its series E cumulative redeemable preferred shares surrendered or (2) the cash received. Any cash a shareholder receives, up to the amount of income or gain recognized, would generally be characterized as a dividend to the extent that a surrender of series D cumulative convertible preferred shares or series E cumulative redeemable preferred shares, as applicable, to us for cash only would be taxable as a dividend, taking into account the surrendering shareholder's continuing actual or constructive ownership interest in our shares, if any, as discussed above, and the balance of the recognized amount, if any, will be gain. A U.S. shareholder's basis in its common shares received would be equal to the basis for, as applicable, the series D cumulative convertible preferred shares or series E cumulative redeemable preferred shares surrendered, less any cash received plus any income or gain recognized. A U.S. shareholder's holding period in the common shares received would be the same as the holding period for, as applicable, the series D cumulative convertible preferred shares or series E cumulative redeemable preferred shares surrendered. If, in addition to common shares, upon conversion or repurchase a U.S. shareholder receives rights or warrants to acquire our common shares or other of our securities, then the receipt of the rights or warrants may be taxable, and we encourage you to consult your tax advisor as to the consequences of the receipt of rights or warrants upon conversion or repurchase.

        A U.S. shareholder generally will not recognize any income, gain or loss upon conversion of series D cumulative convertible preferred shares or series E cumulative redeemable preferred shares into common shares except with respect to cash, if any, received in lieu of a fractional common share. A U.S. shareholder's basis in its common shares received would be equal to the basis for, as applicable, the series D cumulative convertible preferred shares or series E cumulative redeemable preferred shares surrendered, less any basis allocable to any fractional share exchanged for cash. A U.S. shareholder's holding period in the common shares received would be the same as the holding period for, as applicable, the series D cumulative convertible preferred shares or series E cumulative redeemable preferred shares surrendered. Any cash received in lieu of a fractional common share upon conversion will be treated as a payment in exchange for the fractional common share. Accordingly, receipt of cash in lieu of a fractional share generally will result in capital gain or loss, measured by the difference between the cash received for the fractional share and the adjusted tax basis attributable to the fractional share. If, in addition to common shares, upon conversion a U.S. shareholder receives rights or warrants to acquire our common shares or other of our securities, then the receipt of the rights or warrants may be taxable, and we encourage you to consult your tax advisor as to the consequences of the receipt of rights or warrants upon conversion.

        Effective July 1, 2010, our reverse stock split resulted in a one for four combination of our common shares. The reverse stock split was a tax-free recapitalization to us and to our U.S. shareholders pursuant to Section 368(a)(1)(E) of the IRC. Thus, none of our U.S. shareholders would have recognized gain or loss for federal income tax purposes as a result of exchanging pre-combination common shares for post-combination common shares pursuant to the reverse stock split. The holding

28


Table of Contents

period of the post-combination common shares received by a U.S. shareholder pursuant to the reverse stock split includes the holding period of the pre-combination common shares surrendered therefor, provided that the surrendered pre-combination common shares were held as a capital asset on the date of the split. The aggregate tax basis of the post-combination common shares received by a shareholder pursuant to the reverse stock split equals the aggregate tax basis of the pre-combination common shares surrendered therefor.

        For taxable years beginning after December 31, 2012, U.S. holders who are individuals, estates or trusts will generally be required to pay a new 3.8% Medicare tax on their net investment income (including dividends on and gains from the sale or other disposition of our shares), or in the case of estates and trusts on their net investment income that is not distributed, in each case to the extent that their total adjusted income exceeds applicable thresholds.

        The IRC imposes a penalty for the failure to properly disclose a "reportable transaction." A reportable transaction currently includes, among other things, a sale or exchange of our shares resulting in a tax loss in excess of (a) $10 million in any single year or $20 million in any combination of years in the case of our shares held by a C corporation or by a partnership with only C corporation partners or (b) $2 million in any single year or $4 million in any combination of years in the case of our shares held by any other partnership or an S corporation, trust or individual, including losses that flow through pass through entities to individuals. A taxpayer discloses a reportable transaction by filing IRS Form 8886 with its federal income tax return and, in the first year of filing, a copy of Form 8886 must be sent to the IRS's Office of Tax Shelter Analysis. The penalty for failing to disclose a reportable transaction is generally $10,000 in the case of a natural person and $50,000 in any other case.

        Noncorporate U.S. shareholders who borrow funds to finance their acquisition of our shares could be limited in the amount of deductions allowed for the interest paid on the indebtedness incurred. Under Section 163(d) of the IRC, interest paid or accrued on indebtedness incurred or continued to purchase or carry property held for investment is generally deductible only to the extent of the investor's net investment income. A U.S. shareholder's net investment income will include ordinary income dividend distributions received from us and, if an appropriate election is made by the shareholder, capital gain dividend distributions and qualified dividends received from us; however, distributions treated as a nontaxable return of the shareholder's basis will not enter into the computation of net investment income.

Taxation of Tax-Exempt Shareholders

        Subject to the pension-held REIT rules discussed below, our distributions made to shareholders that are tax-exempt pension plans, individual retirement accounts, or other qualifying tax-exempt entities should not constitute unrelated business taxable income, provided that the shareholder has not financed its acquisition of our shares with "acquisition indebtedness" within the meaning of the IRC, and provided further that, consistent with our present intent, we do not hold a residual interest in a real estate mortgage investment conduit.

        Tax-exempt pension trusts that own more than 10% by value of a "pension-held REIT" at any time during a taxable year may be required to treat a percentage of all dividends received from the pension-held REIT during the year as unrelated business taxable income. This percentage is equal to the ratio of:

29


Table of Contents

except that this percentage shall be deemed to be zero unless it would otherwise equal or exceed 5%. A REIT is a pension-held REIT if:

A REIT is predominantly held by tax-exempt pension trusts if at least one tax-exempt pension trust owns more than 25% by value of the REIT's stock or beneficial interests, or if one or more tax-exempt pension trusts, each owning more than 10% by value of the REIT's stock or beneficial interests, own in the aggregate more than 50% by value of the REIT's stock or beneficial interests. Because of the share ownership concentration restrictions in our declaration of trust and bylaws, we believe that we are not and will not be a pension-held REIT. However, because our shares are publicly traded, we cannot completely control whether or not we are or will become a pension-held REIT.

        Social clubs, voluntary employee benefit associations, supplemental unemployment benefit trusts and qualified group legal services plans exempt from federal income taxation under Sections 501(c)(7), (c)(9), (c)(17) and (c)(20) of the IRC, respectively, are subject to different unrelated business taxable income rules, which generally will require them to characterize distributions from a REIT as unrelated business taxable income. In addition, these prospective investors should consult their own tax advisors concerning any "set aside" or reserve requirements applicable to them.

Taxation of Non-U.S. Shareholders

        The rules governing the United States federal income taxation of non-U.S. shareholders are complex, and the following discussion is intended only as a summary of these rules. If you are a non-U.S. shareholder, we urge you to consult with your own tax advisor to determine the impact of United States federal, state, local, and foreign tax laws, including any tax return filing and other reporting requirements, with respect to your investment in our shares.

        In general, a non-U.S. shareholder will be subject to regular United States federal income tax in the same manner as a U.S. shareholder with respect to its investment in our shares if that investment is effectively connected with the non-U.S. shareholder's conduct of a trade or business in the United States (and, if provided by an applicable income tax treaty, is attributable to a permanent establishment or fixed base the non-U.S. shareholder maintains in the United States). In addition, a corporate non-U.S. shareholder that receives income that is or is deemed effectively connected with a trade or business in the United States may also be subject to the 30% branch profits tax under Section 884 of the IRC, which is payable in addition to regular United States federal corporate income tax. The balance of this discussion of the United States federal income taxation of non-U.S. shareholders addresses only those non-U.S. shareholders whose investment in our shares is not effectively connected with the conduct of a trade or business in the United States.

        A distribution by us to a non-U.S. shareholder that is not attributable to gain from the sale or exchange of a United States real property interest and that is not designated as a capital gain dividend will be treated as an ordinary income dividend to the extent that it is made out of current or accumulated earnings and profits. A distribution of this type will generally be subject to United States federal income tax and withholding at the rate of 30%, or at a lower rate if the non-U.S. shareholder has in the manner prescribed by the IRS demonstrated its entitlement to benefits under a tax treaty. In the case of any in kind distributions of property, we or other applicable withholding agents will collect the amount required to be withheld by reducing to cash for remittance to the IRS a sufficient portion of the property that the non-U.S. shareholder would otherwise receive, and the non-U.S. shareholder may bear brokerage or other costs for this withholding procedure. Because we cannot determine our

30


Table of Contents

current and accumulated earnings and profits until the end of the taxable year, withholding at the rate of 30% or applicable lower treaty rate will generally be imposed on the gross amount of any distribution to a non-U.S. shareholder that we make and do not designate a capital gain dividend. Notwithstanding this withholding on distributions in excess of our current and accumulated earnings and profits, these distributions are a nontaxable return of capital to the extent that they do not exceed the non-U.S. shareholder's adjusted basis in our shares, and the nontaxable return of capital will reduce the adjusted basis in these shares. To the extent that distributions in excess of current and accumulated earnings and profits exceed the non-U.S. shareholder's adjusted basis in our shares, the distributions will give rise to tax liability if the non-U.S. shareholder would otherwise be subject to tax on any gain from the sale or exchange of these shares, as discussed below. A non-U.S. shareholder may seek a refund from the IRS of amounts withheld on distributions to him in excess of our current and accumulated earnings and profits.

        From time to time, some of our distributions may be attributable to the sale or exchange of United States real property interests. However, capital gain dividends that are received by a non-U.S. shareholder, as well as dividends attributable to our sales of United States real property interests, will be subject to the taxation and withholding regime applicable to ordinary income dividends and the branch profits tax will not apply, provided that (1) these dividends are received with respect to a class of shares that is "regularly traded" on a domestic "established securities market" such as the New York Stock Exchange, or the NYSE, both as defined by applicable Treasury regulations, and (2) the non-U.S. shareholder does not own more than 5% of that class of shares at any time during the one-year period ending on the date of distribution of the capital gain dividends. If both of these provisions are satisfied, qualifying non-U.S. shareholders will not be subject to withholding either on capital gain dividends or on dividends that are attributable to our sales United States real property interests as though those amounts were effectively connected with a United States trade or business, and qualifying non-U.S. shareholders will not be required to file United States federal income tax returns or pay branch profits tax in respect of these dividends. Instead, these dividends will be subject to United States federal income tax and withholding as ordinary dividends, currently at a 30% tax rate unless reduced by applicable treaty, as discussed below. Although there can be no assurance in this regard, we believe that our common shares and each class of our preferred shares have been and will remain "regularly traded" on a domestic "established securities market" within the meaning of applicable Treasury regulations; however, we can provide no assurance that our shares will continue to be "regularly traded" on a domestic "established securities market" in future taxable years.

        Except as discussed above, for any year in which we qualify as a REIT, distributions that are attributable to gain from the sale or exchange of a United States real property interest are taxed to a non-U.S. shareholder as if these distributions were gains effectively connected with a trade or business in the United States conducted by the non-U.S. shareholder. Accordingly, a non-U.S. shareholder that does not qualify for the special rule above will be taxed on these amounts at the normal capital gain and other tax rates applicable to a U.S. shareholder, subject to any applicable alternative minimum tax and to a special alternative minimum tax in the case of nonresident alien individuals; such a non-U.S. shareholder will be required to file a United States federal income tax return reporting these amounts, even if applicable withholding is imposed as described below; and such a non-U.S. shareholder that is also a corporation may owe the 30% branch profits tax under Section 884 of the IRC in respect of these amounts. We or other applicable withholding agents will be required to withhold from distributions to such non-U.S. shareholders, and remit to the IRS, 35% of the maximum amount of any distribution that could be designated as a capital gain dividend. In addition, for purposes of this withholding rule, if we designate prior distributions as capital gain dividends, then subsequent distributions up to the amount of the designated prior distributions will be treated as capital gain dividends. The amount of any tax withheld is creditable against the non-U.S. shareholder's United States federal income tax liability, and the non-U.S. shareholder may file for a refund from the IRS of any amount of withheld tax in excess of that tax liability.

        A special "wash sale" rule applies to a non-U.S. shareholder who owns any class of our shares if (1) the shareholder owns more than 5% of that class of shares at any time during the one-year period ending on the date of the distribution described below, or (2) that class of our shares is not, within the meaning of applicable Treasury regulations, "regularly traded" on a domestic "established securities market" such as the NYSE. Although there can be no assurance in this regard, we believe that our common shares and each class of our preferred shares have been and will remain "regularly traded" on a domestic "established securities market" within the meaning of applicable Treasury regulations, all as discussed above; however, we can provide no assurance that our shares will continue to be "regularly traded" on a domestic "established securities market" in future taxable years. We thus anticipate this wash sale rule to apply, if at all, only to a non-U.S. shareholder that owns more than 5% of either our common shares or any class of our preferred shares. Such a non-U.S. shareholder will be treated as having made a "wash sale" of our shares if it (1) disposes of an interest in our shares during the 30 days preceding the ex-dividend date of a distribution by us that, but for such disposition, would have been treated by the non-U.S. shareholder in whole or in part as gain from the sale or exchange of a United States real property interest, and then (2) acquires or enters into a contract to acquire a substantially identical interest in our shares, either actually or constructively through a related party, during the 61-day period beginning 30 days prior to the ex-dividend date. In the event of such a wash sale, the non-U.S. shareholder will have gain from the sale or exchange of a United States real property interest in an amount equal to the portion of the distribution that, but for the wash sale, would have been a gain from the sale or exchange of a United States real property interest. As discussed above, a non-U.S. shareholder's gain from the sale or exchange of a United States real property interest can trigger increased United States taxes, such as the branch profits tax applicable to non-U.S. corporations, and increased United States tax filing requirements.

        If for any taxable year we designate capital gain dividends for our shareholders, then a portion of the capital gain dividends we designate will be allocated to the holders of a particular class of shares on a percentage basis equal to the ratio of the amount of the total dividends paid or made available for the year to the holders of that class of shares to the total dividends paid or made available for the year to holders of all classes of our shares.

        Tax treaties may reduce the withholding obligations on our distributions. Under some treaties, however, rates below 30% that are applicable to ordinary income dividends from United States corporations may not apply to ordinary income dividends from a REIT or may apply only if the REIT meets certain additional conditions. You must generally use an applicable IRS Form W-8, or substantially similar form, to claim tax treaty benefits. If the amount of tax withheld with respect to a distribution to a non-U.S. shareholder exceeds the shareholder's United States federal income tax liability with respect to the distribution, the non-U.S. shareholder may file for a refund of the excess from the IRS. The 35% withholding tax rate discussed above on some capital gain dividends corresponds to the maximum income tax rate applicable to corporate non-U.S. shareholders but is higher than the current 15% and 25% maximum rates on capital gains generally applicable to noncorporate non-U.S. shareholders. Treasury regulations also provide special rules to determine whether, for purposes of determining the applicability of a tax treaty, our distributions to a non-U.S. shareholder that is an entity should be treated as paid to the entity or to those owning an interest in that entity, and whether the entity or its owners are entitled to benefits under the tax treaty. In the case of any in kind distributions of property, we or other applicable withholding agents will have to collect the amount required to be withheld by reducing to cash for remittance to the IRS a sufficient portion of the property that the non-U.S. shareholder would otherwise receive, and the non-U.S. shareholder may bear brokerage or other costs for this withholding procedure.

        Non-U.S. stockholders should generally be able to treat amounts we designate as retained but constructively distributed capital gains in the same manner as actual distributions of capital gain dividends by us. In addition, a non-U.S. stockholder should be able to offset as a credit against its

32


Table of Contents

federal income tax liability the proportionate share of the tax paid by us on such retained but constructively distributed capital gains. A non-U.S. stockholder may file for a refund from the IRS for the amount that the non-U.S. stockholder's proportionate share of tax paid by us exceeds its federal income tax liability on the constructively distributed capital gains.

        If our shares are not "United States real property interests" within the meaning of Section 897 of the IRC, then a non-U.S. shareholder's gain on sale of these shares (including for this purpose a conversion of our series D cumulative convertible preferred shares or our series E cumulative redeemable preferred shares into common shares) generally will not be subject to United States federal income taxation, except that a nonresident alien individual who was in the United States for 183 days or more during the taxable year may be subject to a 30% tax on this gain. Our shares will not constitute a United States real property interest if we are a "domestically controlled REIT." A domestically controlled REIT is a REIT in which at all times during the preceding five-year period less than 50% in value of its shares is held directly or indirectly by foreign persons. We believe that we have been and will remain a domestically controlled REIT and thus a non-U.S. shareholder's gain on sale of our shares will not be subject to United States federal income taxation. However, because our shares are publicly traded, we can provide no assurance that we have been or will remain a domestically controlled REIT. If we are not a domestically controlled REIT, a non-U.S. shareholder's gain on sale of our shares will not be subject to United States federal income taxation as a sale of a United States real property interest if that class of shares is "regularly traded," as defined by applicable Treasury regulations, on an established securities market like the NYSE, and the non-U.S. shareholder has at all times during the preceding five years owned 5% or less by value of that class of shares. In this regard, because the shares of others may be redeemed, and in the case of the series D cumulative convertible preferred shares, are convertible, a non-U.S. shareholder's percentage interest in a class of our shares may increase even if it acquires no additional shares in that class. If the gain on the sale of our shares were subject to United States federal income taxation, the non-U.S. shareholder will generally be subject to the same treatment as a U.S. shareholder with respect to its gain, will be required to file a United States federal income tax return reporting that gain, and a corporate non-U.S. shareholder might owe branch profits tax under Section 884 of the IRC. A purchaser of our shares from a non-U.S. shareholder will not be required to withhold on the purchase price if the purchased shares are regularly traded on an established securities market or if we are a domestically controlled REIT. Otherwise, a purchaser of our shares from a non-U.S. shareholder may be required to withhold 10% of the purchase price paid to the non-U.S. shareholder and to remit the withheld amount to the IRS.

        Effective July 1, 2010, our reverse stock split resulted in a one for four combination of our common shares. The reverse stock split was a tax-free recapitalization to us pursuant to Section 368(a)(1)(E) of the IRC. Provided that we were at the time of the reverse stock split a domestically controlled REIT, as discussed above, or alternatively that our common shares at the time of the reverse stock split were "regularly traded" and a non-U.S. shareholder at all times during the preceding five years owned 5% or less by value of our common shares, each as discussed above, then the reverse stock split was also a tax-free recapitalization to the non-U.S. shareholder pursuant to Section 368(a)(1)(E) of the IRC. In that event, the non-U.S. shareholder would not have recognized gain or loss for federal income tax purposes as a result of exchanging pre-combination common shares for post-combination common shares pursuant to the reverse stock split; the holding period of the post-combination common shares received by a non-U.S. shareholder pursuant to the reverse stock split would include the holding period of the pre-combination common shares surrendered therefor, provided that the surrendered pre-combination common shares were held as a capital asset on the date of the split; and, the aggregate tax basis of the post-combination common shares received by a non-U.S. shareholder pursuant to the reverse stock split would equal the aggregate tax basis of the pre-combination common shares surrendered therefor. However, at the time of the reverse stock split, if we were not a domestically controlled REIT and if either our common shares were not "regularly traded" or a non-U.S. shareholder exceeded the above 5% ownership limitation, then the non-U.S.

33


Table of Contents

shareholder may be required to file a U.S. federal income tax return for the taxable year of the reverse stock split in order to avoid recognition of gain on the reverse stock split; we urge any such situated non-U.S. shareholder to consult with its own tax advisor regarding the consequences of our 2010 reverse stock split.

Withholding and Information Reporting

        Information reporting and backup withholding may apply to distributions or proceeds paid to our shareholders under the circumstances discussed below. The backup withholding rate is currently 28% and is scheduled to increase to 31% after 2012. Amounts withheld under backup withholding are generally not an additional tax and may be refunded by the IRS or credited against the shareholder's federal income tax liability. In the case of any in kind distributions of property by us to a shareholder, we or other applicable withholding agents will have to collect any applicable backup withholding by reducing to cash for remittance to the IRS a sufficient portion of the property that our shareholder would otherwise receive, and the shareholder may bear brokerage or other costs for this withholding procedure.

        A U.S. shareholder will be subject to backup withholding when it receives distributions on our shares or proceeds upon the sale, exchange, redemption, retirement or other disposition of our shares, unless the U.S. shareholder properly executes, or has previously properly executed, under penalties of perjury an IRS Form W-9 or substantially similar form that:

If the U.S. shareholder has not provided and does not provide its correct taxpayer identification number on the IRS Form W-9 or substantially similar form, it may be subject to penalties imposed by the IRS, and we or other applicable withholding agents may have to withhold a portion of any distributions or proceeds paid to such U.S. shareholder. Unless the U.S. shareholder has established on a properly executed IRS Form W-9 or substantially similar form that it comes within an enumerated exempt category, distributions or proceeds on our shares paid to it during the calendar year, and the amount of tax withheld, if any, will be reported to it and to the IRS.

        Distributions on our shares to a non-U.S. shareholder during each calendar year and the amount of tax withheld, if any, will generally be reported to the non-U.S. shareholder and to the IRS. This information reporting requirement applies regardless of whether the non-U.S. shareholder is subject to withholding on distributions on our shares or whether the withholding was reduced or eliminated by an applicable tax treaty. Also, distributions paid to a non-U.S. shareholder on our shares may be subject to backup withholding, unless the non-U.S. shareholder properly certifies its non-U.S. shareholder status on an IRS Form W-8 or substantially similar form in the manner described above. Similarly, information reporting and backup withholding will not apply to proceeds a non-U.S. shareholder receives upon the sale, exchange, redemption, retirement or other disposition of our shares, if the non-U.S. shareholder properly certifies its non-U.S. shareholder status on an IRS Form W-8 or substantially similar form. Even without having executed an IRS Form W-8 or substantially similar form, however, in some cases information reporting and backup withholding will not apply to proceeds that a non-U.S. shareholder receives upon the sale, exchange, redemption, retirement or other disposition of our shares if the non-U.S. shareholder receives those proceeds through a broker's foreign office.

34


Table of Contents

        Increased reporting obligations are scheduled to be imposed on non-United States financial institutions and other non-United States entities for purposes of identifying accounts and investments held directly or indirectly by United States persons. The failure to comply with these additional information reporting, certification and other specified requirements could result in withholding tax being imposed on payments of dividends and sales proceeds to applicable shareholders or intermediaries. Specifically, a 30% withholding tax is imposed on dividends on and gross proceeds from the sale or other disposition of our shares paid to a foreign financial institution or to a foreign nonfinancial entity, unless (1) the foreign financial institution undertakes applicable diligence and reporting obligations or (2) the foreign nonfinancial entity either certifies it does not have any substantial United States owners or furnishes identifying information regarding each substantial United States owner. In addition, if the payee is a foreign financial institution, it generally must enter into an agreement with the United States Treasury that requires, among other things, that it undertake to identify accounts held by applicable United States persons or United States-owned foreign entities, annually report specified information about such accounts, and withhold 30% on payments to noncertified holders. Pursuant to IRS guidance, future regulations will provide that such withholding applies only to dividends paid on or after January 1, 2014, and to other "withholdable payments" (including payments of gross proceeds from a sale or other disposition of our shares) made on or after January 1, 2015. If you hold our shares through a non-United States intermediary or if you are a non-United States person, we urge you to consult your own tax advisor regarding foreign account tax compliance.

Other Tax Consequences

        Our tax treatment and that of our shareholders may be modified by legislative, judicial, or administrative actions at any time, which actions may be retroactive in effect. The rules dealing with federal income taxation are constantly under review by the Congress, the IRS and the Treasury Department, and statutory changes, new regulations, revisions to existing regulations, and revised interpretations of established concepts are issued frequently. Likewise, the rules regarding taxes other than federal income taxes may also be modified. No prediction can be made as to the likelihood of passage of new tax legislation or other provisions, or the direct or indirect effect on us and our shareholders. Revisions to tax laws and interpretations of these laws could adversely affect the tax or other consequences of an investment in our shares. We and our shareholders may also be subject to taxation by state, local or other jurisdictions, including those in which we or our shareholders transact business or reside. These tax consequences may not be comparable to the federal income tax consequences discussed above.


ERISA PLANS, KEOGH PLANS AND INDIVIDUAL RETIREMENT ACCOUNTS

General Fiduciary Obligations

        Fiduciaries of a pension, profit-sharing or other employee benefit plan subject to Title I of the Employee Retirement Income Security Act of 1974, as amended, or ERISA, must consider whether:

        Trustees and other fiduciaries of an ERISA plan may incur personal liability for any loss suffered by the plan on account of a violation of their fiduciary responsibilities. In addition, these fiduciaries may be subject to a civil penalty of up to 20% of any amount recovered by the plan on account of a

35


Table of Contents

violation. Fiduciaries of any IRA, Roth IRA, tax-favored account (such as an Archer MSA, Coverdell education savings account or health savings account), Keogh Plan or other qualified retirement plan not subject to Title I of ERISA, or non-ERISA plans, should consider that a plan may only make investments that are authorized by the appropriate governing instrument.

        Fiduciaries considering an investment in our securities should consult their own legal advisors if they have any concern as to whether the investment is consistent with the foregoing criteria or is otherwise appropriate. The sale of our securities to a plan is in no respect a representation by us or any underwriter of the securities that the investment meets all relevant legal requirements with respect to investments by plans generally or any particular plan, or that the investment is appropriate for plans generally or any particular plan.

Prohibited Transactions

        Fiduciaries of ERISA plans and persons making the investment decision for an IRA or other non-ERISA plan should consider the application of the prohibited transaction provisions of ERISA and the IRC in making their investment decision. Sales and other transactions between an ERISA or non-ERISA plan, and persons related to it, are prohibited transactions. The particular facts concerning the sponsorship, operations and other investments of an ERISA plan or non-ERISA plan may cause a wide range of other persons to be treated as disqualified persons or parties in interest with respect to it. A prohibited transaction, in addition to imposing potential personal liability upon fiduciaries of ERISA plans, may also result in the imposition of an excise tax under the IRC or a penalty under ERISA upon the disqualified person or party in interest with respect to the plan. If the disqualified person who engages in the transaction is the individual on behalf of whom an IRA or Roth IRA is maintained or his beneficiary, the IRA or Roth IRA may lose its tax-exempt status and its assets may be deemed to have been distributed to the individual in a taxable distribution on account of the prohibited transaction, but no excise tax will be imposed. Fiduciaries considering an investment in our securities should consult their own legal advisors as to whether the ownership of our securities involves a prohibited transaction.

"Plan Assets" Considerations

        The U.S. Department of Labor, which has administrative responsibility over ERISA plans as well as non-ERISA plans, has issued a regulation defining "plan assets." The regulation generally provides that when an ERISA or non-ERISA plan acquires a security that is an equity interest in an entity and that security is neither a "publicly offered security" nor a security issued by an investment company registered under the Investment Company Act of 1940, as amended, the ERISA plan's or non-ERISA plan's assets include both the equity interest and an undivided interest in each of the underlying assets of the entity, unless it is established either that the entity is an operating company or that equity participation in the entity by benefit plan investors is not significant.

        Each class of our shares (that is, our common shares and any class of preferred shares that we have issued or may issue) must be analyzed separately to ascertain whether it is a publicly offered security. The regulation defines a publicly offered security as a security that is "widely held," "freely transferable" and either part of a class of securities registered under the Exchange Act, or sold under an effective registration statement under the Securities Act of 1933, as amended, provided the securities are registered under the Exchange Act within 120 days after the end of the fiscal year of the issuer during which the offering occurred. Each class of our outstanding shares has been registered under the Exchange Act within the necessary time frame to satisfy the foregoing condition.

        The regulation provides that a security is "widely held" only if it is part of a class of securities that is owned by 100 or more investors independent of the issuer and of one another. However, a security will not fail to be "widely held" because the number of independent investors falls below 100

36


Table of Contents

subsequent to the initial public offering as a result of events beyond the issuer's control. We believe our common shares and our preferred shares have been and will remain widely held, and we expect the same to be true of any additional class of preferred shares that we may issue, but we can give no assurances in this regard.

        The regulation provides that whether a security is "freely transferable" is a factual question to be determined on the basis of all relevant facts and circumstances. The regulation further provides that, where a security is part of an offering in which the minimum investment is $10,000 or less, some restrictions on transfer ordinarily will not, alone or in combination, affect a finding that these securities are freely transferable. The restrictions on transfer enumerated in the regulation as not affecting that finding include:

        We believe that the restrictions imposed under our declaration of trust and bylaws on the transfer of shares do not result in the failure of our shares to be "freely transferable." Furthermore, we believe that there exist no other facts or circumstances limiting the transferability of our shares which are not included among those enumerated as not affecting their free transferability under the regulation, and we do not expect or intend to impose in the future, or to permit any person to impose on our behalf, any limitations or restrictions on transfer which would not be among the enumerated permissible limitations or restrictions.

        Assuming that each class of our shares will be "widely held" and that no other facts and circumstances exist which restrict transferability of these shares, we have received an opinion of our counsel, Sullivan & Worcester LLP, that our shares will not fail to be "freely transferable" for purposes of the regulation due to the restrictions on transfer of the shares under our declaration of trust and bylaws and that under the regulation each class of our currently outstanding shares is publicly offered and our assets will not be deemed to be "plan assets" of any ERISA plan or non-ERISA plan that acquires our shares in a public offering.

Item 1A.    Risk Factors.

        Our business faces many risks. The risks described below may not be the only risks we face but are the risks we know of that we believe may be material at this time. Additional risks that we do not yet know of, or that we currently think are immaterial, may also impair our business operations or financial results. If any of the events or circumstances described in the following risks occurs, our business, financial condition or results of operations could suffer and the trading price of our securities could decline. Investors and prospective investors should consider the following risks and the information contained under the heading "Warning Concerning Forward Looking Statements" before deciding whether to invest in our securities.

Risks Related to Our Business

If the current high unemployment rate in the U.S. continues or worsens, the occupancy and rents at our properties may decline.

        If the current high unemployment rate in the U.S. worsens or continues for a prolonged period, the demand to lease office and industrial space may decline. Reductions in tenant demand to lease space are likely to result in reduced occupancy and rents at our properties. Many of our operating costs, such as utilities, real estate taxes, insurance, etc., are fixed. If our rents decline our income and cash flow available for distribution will decline and we may become unable to maintain our current rate of distributions to shareholders.

Financial markets are still recovering from a period of disruption and recession, and we are unable to predict if the economy will continue to improve.

        The financial markets are still recovering from a recession, which created volatile market conditions, resulted in a decrease in availability of business credit and led to the insolvency, closure or acquisition of a number of financial institutions. While the markets showed signs of stabilization in 2009 and improvement in 2010 and 2011, it remains unclear when the economy will fully recover to pre-recession levels. Continued weakness in the U.S. economy generally or a new recession would likely adversely affect our financial condition and that of our tenants and could impact the ability of our tenants to pay rent to us.

We may be unable to access the capital necessary to repay debts, invest in our properties or fund acquisitions.

        To retain our status as a REIT, we are required to distribute at least 90% of our annual REIT taxable income (excluding capital gains) and satisfy a number of organizational and operational requirements to which REITs are subject. Accordingly, we are generally not able to retain sufficient cash from operations to repay debts, invest in our properties and fund acquisitions. Our business and growth strategies depend, in part, upon our ability to raise additional capital at reasonable costs to repay our debts, invest in our properties and fund new acquisitions. Because of the volatility in the availability of capital to businesses on a global basis and the increased volatility in most debt and equity markets generally, our ability to raise reasonably priced capital is not guaranteed; we may be unable to raise reasonably priced capital because of reasons related to our business or for reasons beyond our control, such as market conditions. If we are unable to raise reasonably priced capital, our business and growth strategies may fail and we may be unable to remain a REIT.

We are currently dependent upon economic conditions in our six core markets: Metro Philadelphia, Pennsylvania; Oahu, Hawaii; Metro Chicago, Illinois; Metro Denver, Colorado; Australia and Metro Washington, DC.

        Approximately 41.6% of our revenues in fiscal year 2011 were derived from properties located in our six core markets: Metro Philadelphia, PA; Oahu, Hawaii; Metro Chicago, IL; Metro Denver, CO; Australia and Metro Washington, DC. A continued slowing in economic conditions in these markets will likely result in reduced demand from tenants for our properties. A significant economic downturn in one or more of these areas could adversely affect our results of operations.

We face significant competition.

        All of our properties face competition for tenants. Some competing properties may be newer, better located and more attractive to tenants. Competing properties may have lower rates of occupancy than our properties, which may result in competing owners leasing available space at lower effective rents than we offer at our properties. This competition may affect our ability to attract and retain tenants and may reduce the rents we are able to charge.

        Also, we face competition for acquisition opportunities from other investors, and this competition may subject us to the following risks:

Our failure or inability to meet certain terms of our term loan and revolving credit facility would adversely affect our business and may prevent our paying distributions to you.

        Both our term loan and revolving credit facility include various conditions to our borrowing and various financial and other covenants and events of default. We may not be able to satisfy all of these conditions or may default on some of these covenants for various reasons, including matters which are beyond our control. If we are unable to borrow under our revolving credit facility we may be unable to meet our business obligations or to grow by buying additional properties, or we may be required to sell some of our properties. If we default under our term loan or our revolving credit facility at a time when borrowed amounts are outstanding under these instruments, our lenders may demand immediate payment. Any default under our term loan or our revolving credit facility would likely have serious and adverse consequences to us and would likely cause the market price of our securities to materially decline and may prevent our paying distributions to our shareholders.

Increasing interest rates may adversely affect us and the value of an investment in our securities.

        Interest rates are currently at historically low levels and may increase. There are three principal ways that increasing interest rates may adversely affect us and the value of an investment in our securities:

39


Table of Contents

Changes in the government's requirements for leased space may adversely affect us.

        Approximately 2% of our total rents pursuant to existing leases as of December 31, 2011, come from government tenants. Many of our leases with government agencies allow the tenants to vacate the leased premises before the stated term expires with little or no liability. Historically, our government tenants have only rarely exercised lease termination rights and have regularly renewed leases. Nonetheless, for fiscal policy reasons, security concerns or otherwise, some or all of our government tenants may decide to vacate our properties. If a significant number of such terminations occur, our income and cash flow may materially decline and our ability to pay regular distributions to shareholders may be jeopardized.

Our acquisitions may not be successful.

        Our business strategy contemplates acquisitions of additional properties. We cannot assure investors that acquisitions we make will prove to be successful. We might encounter unanticipated difficulties and expenditures relating to any acquired properties. Newly acquired properties might require significant management attention that would otherwise be devoted to our ongoing business. We might never realize the anticipated benefits of our acquisitions. Notwithstanding pre-acquisition due diligence, we do not believe that it is possible to fully understand a property before it is owned and operated for an extended period of time. For example, we could acquire a property that contains undisclosed defects in design or construction. In addition, after our acquisition of a property, the market in which the acquired property is located may experience unexpected changes that adversely affect the property's value. The occupancy of properties that we acquire may decline during our ownership, and rents that are in effect at the time a property is acquired may decline thereafter. Also, our property operating costs for acquisitions may be higher than we anticipate and acquisitions of properties may not yield the returns we expect and, if financed using debt or new equity issuances, may result in shareholder dilution. For these reasons, among others, our property acquisitions may cause us to experience losses.

Acquisition and ownership of real estate is subject to environmental and climate change risks.

        Acquisition and ownership of real estate is subject to risks associated with environmental hazards. We may be liable for environmental hazards at, or migrating from, our properties, including those created by prior owners or occupants, existing tenants, abutters or other persons. Our properties may be subject to environmental laws for certain hazardous substances used to maintain these properties, such as chemicals used to clean, pesticides and lawn maintenance materials, and for other conditions, such as the presence of harmful mold. Various federal and state laws impose environmental liabilities upon property owners, such as us, for any environmental damages arising on properties they own or occupy, and we are not assured that we will not be held liable for environmental investigation and clean up at, or near, our properties, including environmental damages at sites we own and lease to our tenants. As an owner or previous owner of properties which contain environmental hazards, we also may be liable to pay damages to governmental agencies or third parties for costs and damages they incur arising from environmental hazards at the properties. Moreover, the costs and damages which may arise from environmental hazards are often difficult to project.

        The current political debate about climate change has resulted in various treaties, laws and regulations which are intended to limit carbon emissions. We believe these laws being enacted or proposed may cause energy costs at our properties to increase, but we do not expect the direct impact of these increases to be material to our results of operations because the increased costs either would be the responsibility of our tenants directly or in large part may be passed through by us to our tenants as additional lease payments. Although we do not believe it is likely in the foreseeable future, laws enacted to mitigate climate change may make some of our buildings obsolete or cause us to make material investments in our properties which could materially and adversely affect our financial condition and results of operations.

Real estate ownership creates risks and liabilities.

        Our business is subject to risks associated with real estate ownership, including:

We have substantial debt obligations and may incur additional debt.

        As of December 31, 2011, we had $3.6 billion in debt outstanding, which was 50.1% of our total book capitalization. Our note indenture, revolving credit facility and term loan permit us and our subsidiaries to incur additional debt, including secured debt. If we default in paying any of our debts or honoring our debt covenants, it may create one or more cross defaults, our debts may be accelerated and we could be forced to liquidate our assets for less than the values we would receive in a more orderly process.

We rely on information technology in our operations, and any material failure, inadequacy, interruption or security failure of that technology could harm our business.

        We rely on information technology networks and systems, including the Internet, to process, transmit and store electronic information, and to manage or support a variety of business processes, including financial transactions and records, personal identifying information, tenant and lease data. Some of these systems are owned by RMR. We and RMR purchase some of our information technology from vendors, on whom our systems depend. We and RMR rely on commercially available systems, software, tools and monitoring to provide security for processing, transmission and storage of confidential tenant and other customer information, such as individually identifiable information, including information relating to financial accounts. Although we have taken steps to protect the security of our information systems and the data maintained in those systems, it is possible that our safety and security measures will not be able to prevent the systems' improper functioning or damage, or the improper access or disclosure of personally identifiable information such as in the event of cyber

41


Table of Contents

attacks. Security breaches, including physical or electronic break-ins, computer viruses, attacks by hackers and similar breaches, can create system disruptions, shutdowns or unauthorized disclosure of confidential information. Any failure to maintain proper function, security and availability of our information systems could interrupt our operations, damage our reputation, subject us to liability claims or regulatory penalties and could have a material adverse effect on our business, financial condition and results of operations.

Risks Related to Our Organization and Structure

Ownership limitations and anti-takeover provisions in our declaration of trust, bylaws and rights agreement, as well as certain provisions of Maryland law, may prevent shareholders from receiving a takeover premium or implementing changes.

        Our declaration of trust or bylaws prohibit any shareholder other than RMR and its affiliates from owning directly and by attribution more than 9.8% of the number or value of shares of any class or series of our outstanding shares. These provisions may assist with our REIT compliance under the IRC. However, these provisions may also inhibit acquisitions of a significant stake in us and may prevent a change in our control. Additionally, many provisions contained in our declaration of trust and bylaws and under Maryland law may further deter persons from attempting to acquire control of us and implement changes that may be considered beneficial by some shareholders, including, for example, provisions relating to:

42


Table of Contents

        We maintain a rights agreement whereby, in the event a person or group of persons acquires 10% or more of our outstanding common shares, our shareholders, other than such person or group, will be entitled to purchase additional shares or other securities or property at a discount. In addition, certain provisions of Maryland law may have an anti-takeover effect. For all of these reasons, our shareholders may be unable to realize a change of control premium for any of our shares they own or otherwise effect a change of our policies.

We may change our operational and investment policies without shareholder approval.

        Our Board of Trustees determines our operational and investment policies and may amend or revise our policies, including our policies with respect to our intention to qualify for taxation as a REIT, acquisitions, dispositions, growth, operations, indebtedness, capitalization and distributions, or approve transactions that deviate from these policies, without a vote of, or notice to, our shareholders. Policy changes could adversely affect the market value of our shares and our ability to make distributions to our shareholders.

Our rights and the rights of our shareholders to take action against our Trustees and officers are limited.

        Our declaration of trust limits the liability of our Trustees and officers to us and our shareholders for money damages to the maximum extent permitted under Maryland law. Under current Maryland law, our Trustees and officers will not have any liability to us and our shareholders for money damages other than liability resulting from:

        Our declaration of trust and indemnity contracts require us to indemnify any present or former Trustee or officer to the maximum extent permitted by Maryland law, who is made or threatened to be made a party to a proceeding by reason of his or her service in that capacity. However, except with respect to proceedings to enforce rights to indemnification, we will indemnify any person referenced in the previous sentence in connection with a proceeding initiated by such person against us only if such proceeding is authorized by our declaration of trust or bylaws or by our Board of Trustees or shareholders. In addition, we may be obligated to pay or reimburse the expenses incurred by our present and former Trustees and officers without requiring a preliminary determination of their ultimate entitlement to indemnification. As a result, we and our shareholders may have more limited rights against our present and former Trustees and officers than might otherwise exist absent the provisions in our declaration of trust and indemnity contracts or that might exist with other companies, which could limit your recourse in the event of actions not in your best interest.

Disputes with GOV, SNH and RMR and shareholder litigation against us or our Trustees and officers may be referred to arbitration proceedings.

        Our contracts with GOV, SNH and RMR provide that any dispute arising under those contracts may be referred to binding arbitration. Similarly, our bylaws provide that actions by our shareholders against us or against our Trustees and officers, including derivative and class actions, may be referred to binding arbitration. As a result, we and our shareholders would not be able to pursue litigation for

43


Table of Contents

these disputes in courts against GOV, SNH, RMR or our Trustees or officers. In addition, the ability to collect attorneys' fees or other damages may be limited in the arbitration, which may discourage attorneys from agreeing to represent parties wishing to commence such a proceeding.

Risks Related to Our Taxation

The loss of our tax status as a REIT for U.S. federal income tax purposes could have significant adverse consequences.

        As a REIT, we generally do not pay federal and state income taxes. However, actual qualification as a REIT under the IRC depends on satisfying complex statutory requirements, for which there are only limited judicial and administrative interpretations. We believe that we have been organized and have operated, and will continue to be organized and to operate, in a manner that qualified and will continue to qualify us to be taxed under the IRC as a REIT. However, we cannot be certain that, upon review or audit, the IRS will agree with this conclusion. Furthermore, there is no guarantee that the federal government will not someday eliminate REITs under the IRC.

        Maintaining our status as a REIT will require us to continue to satisfy certain tests concerning, among other things, the nature of our assets, the sources of our income and the amounts we distribute to our shareholders. In order to meet these requirements, it may be necessary for us to sell or forgo attractive investments.

        If we cease to be a REIT, then our ability to raise capital might be adversely affected, we will be in breach under our revolving credit facility, we may be subject to material amounts of federal and state income taxes and the value of our securities likely would decline. In addition, if we lose or revoke our tax status as a REIT for a taxable year, we will generally be prevented from requalifying as a REIT for the next four taxable years. Similarly, our Australian operations benefit from locally available tax concessions which require us to satisfy complex requirements as to which there are only limited judicial and administrative interpretations. We believe that we have operated, and are operating, in compliance with the requirements for these Australian tax concessions. However, we cannot be certain that, upon review or audit, the local tax authority will agree. If we cease to be eligible for these Australian tax concessions, then we may be subject to material amounts of Australian income taxes and the value of our securities likely would decline; in addition, we could be precluded from requalifying for these Australian tax concessions again.

Distributions to shareholders generally will not qualify for reduced tax rates.

        The maximum tax rate for dividends payable by U.S. corporations to individual stockholders is 15% through 2012. Distributions paid by REITs, however, generally are not eligible for this reduced rate. The more favorable rates for corporate dividends could cause investors to perceive that investment in REITs is less attractive than investment in non-REIT entities that pay dividends, thereby reducing the demand and market price of our shares.

Risks Related to Our Relationship with RMR and its Affiliates

We are dependent upon RMR to manage our business and implement our growth strategy.

        We have no employees. Personnel and services that we require are provided to us under contract by RMR. Our ability to achieve our business objectives depends on RMR and its ability to manage our properties, source and complete new acquisitions for us on favorable terms and to execute our financing strategy. Accordingly, our business is dependent upon RMR's business contacts, its ability to successfully hire, train, supervise and manage its personnel and its ability to maintain its operating systems. If we lose the services provided by RMR or its key personnel, our business and growth prospects may decline. We may be unable to duplicate the quality and depth of management available

44


Table of Contents

to us by becoming a self managed company or by hiring another manager. Also, in the event RMR is unwilling or unable to continue to provide management services to us, our cost of obtaining substitute services may be greater than the fees we pay RMR, and as a result our expenses may increase.

Our management structure and our manager's other activities may create conflicts of interest or create the perception of conflicts of interest.

        RMR is authorized to follow broad operating and investment guidelines and, therefore, has discretion in determining the types of properties that will be appropriate investments for us, as well as making our individual operating and investment decisions. Our Board of Trustees periodically reviews our operating and investment guidelines and our individual operating activities and investments, but it does not review or approve each decision made by RMR on our behalf. In addition, in conducting periodic reviews, our Board of Trustees relies primarily on information provided to it by RMR. RMR is beneficially owned by our Managing Trustees, Barry Portnoy and Adam Portnoy. Barry Portnoy is Chairman and an employee of RMR, and Adam Portnoy serves as President, Chief Executive Officer and a director, of RMR. Adam Portnoy is also our President. All of the members of our Board of Trustees, including our Independent Trustees, are members of one or more boards of trustees or directors of other companies managed by RMR. All of our executive officers are also executive officers of RMR. The foregoing individuals may hold equity in or positions with other companies managed by RMR. Such equity ownership and positions by our trustees and officers could create, or appear to create, conflicts of interest with respect to matters involving us, RMR and its affiliates.

        RMR also acts as the manager for three other NYSE-listed REITs: SNH, which primarily owns healthcare, senior living properties and medical office buildings; HPT, which owns hotels and travel centers; and GOV, which owns properties that are majority leased to government tenants. RMR also provides management services to other public and private companies, including Five Star, which operates senior living communities, including independent living and congregate care communities, assisted living communities, nursing homes and hospitals, TA, which operates and franchises travel centers, and Sonesta, which operates, manages and franchises hotels. Additionally, if and when our subsidiary, SIR, completes its IPO, we expect SIR to enter into management agreements with RMR. These multiple responsibilities to public companies and RMR's other businesses could create competition for the time and efforts of RMR and Messrs. Barry Portnoy and Adam Portnoy. Also, RMR's multiple responsibilities to us, SNH and GOV, and if its offering is completed, SIR, may create potential conflicts of interest, or the appearance of such conflicts of interest.

Our management agreements with RMR were negotiated between affiliated parties and may not be as favorable to us as they would have been if negotiated between unaffiliated parties.

        We pay RMR business management fees based in part upon the historical cost of our investments (including acquisition costs) which at any time may be more or less than the fair market value thereof, plus an incentive fee based upon increases in our funds from operations, as defined in our business management agreement with RMR. We also pay RMR property management fees based in part upon the gross rents we collect from tenants and the cost of construction we incur. For more information, see "Business—Manager." Our fee arrangements with RMR could encourage RMR to advocate acquisitions of properties, to undertake unnecessary construction activities or to overpay for acquisitions or construction. These arrangements may also encourage RMR to discourage our sales of properties. Our management agreements were negotiated between affiliated parties, and the terms, including the fees payable to RMR, may not be as favorable to us as they would have been were they negotiated on an arm's length basis between unaffiliated parties.

45


Table of Contents

Our management agreements with RMR may discourage our change of control.

        Termination of our management agreements with RMR would be a default under our revolving credit facility and our term loan unless approved by a majority of our lenders. RMR can terminate its management agreements with us if we experience a change of control. The quality and depth of management available to us by contracting with RMR may not be able to be duplicated by our being a self managed company or by our contracting with unrelated third parties, without considerable cost increases. For these reasons, our management agreements may discourage a change of control of us, including a change of control which might result in payment of a premium for your shares.

Provisions in our transaction agreements with other RMR managed entities and our management agreements with RMR may restrict our investment activities and create conflicts of interest or the perception of conflicts of interest.

        RMR's management agreements with us restrict our ability to make investments in properties that are within the investment focus of another business now or in the future managed by RMR. In addition, RMR has discretion to determine whether a particular investment opportunity is within our investment focus or that of another business managed by RMR. Under our management agreements with RMR, we have also agreed to first offer any property within the principal investment focus of another REIT to which RMR provides management services to such REIT prior to entering into any sale or other disposition arrangement with respect to such property. In addition, our transaction agreements with SNH and GOV have, and we expect our transaction agreement with SIR, which we may enter into with SIR if its offering occurs, to have, restrictions on our right to make investments in properties that are within the investment focus of those other businesses. As a result of these contractual provisions, we have limited ability to invest in properties that are within the investment focus of other businesses managed by RMR. These agreements do not restrict our ability, or the ability of other businesses managed by RMR, to lease properties to any particular tenant, but our management agreements afford RMR discretion to determine which leasing opportunities to present to us or to other businesses managed by RMR. There is no assurance that any conflicts created by these agreements will be resolved in our favor.

The potential for conflicts of interest as a result of our management structure may provoke dissident shareholder activities that result in significant costs.

        In the past, in particular following periods of volatility in the overall market or declines in the market price of a company's securities, shareholder litigation, dissident trustee nominations and dissident proposals have often been instituted against companies alleging conflicts of interest in business dealings with affiliated persons and entities. Our relationship with RMR, with the other businesses and entities to which RMR provides management services, with Messrs. Barry Portnoy and Adam Portnoy and with RMR affiliates may precipitate such activities. These activities, if instituted against us, could result in substantial costs and a diversion of our management's attention, even if the allegations are not substantiated.

We may experience losses from our business dealings with Affiliates Insurance Company.

        We have invested approximately $5.2 million in AIC, we have purchased substantially all our property insurance in a program designed and reinsured in part by AIC, and we are currently investigating the possibilities to expand our relationship with AIC to other types of insurance. We, RMR, SNH, GOV and three other companies to which RMR provides management services each own approximately 14.3% of AIC, and we and those other AIC shareholders participate in a combined insurance program designed and reinsured in part by AIC. Additionally, if and when SIR completes its IPO, we expect that SIR will also invest in AIC and participate in this combined insurance program. Our principal reason for investing in AIC and for purchasing insurance in these programs is to seek to

46


Table of Contents

improve our financial results by obtaining improved insurance coverages at lower costs than may be otherwise available to us or by participating in any profits which we may realize as an owner of AIC. These beneficial financial results may not occur, and we may need to invest additional capital in order to continue to pursue these results. AIC's business involves the risks typical of an insurance business, including the risk that it may not operate profitably. Accordingly, our anticipated financial benefits from our business dealings with AIC may be delayed or not achieved, and we may experience losses from these dealings.

Risks Related to Our Securities

Any notes we may issue will be effectively subordinated to the debts of our subsidiaries and to our secured debt.

        We conduct substantially all of our business through, and substantially all of our properties are owned by, subsidiaries. Consequently, our ability to pay debt service on our outstanding notes and any notes we issue in the future will be dependent upon the cash flow of our subsidiaries and payments by those subsidiaries to us as dividends or otherwise. Our subsidiaries are separate legal entities and have their own liabilities. Payments due on our outstanding notes, and any notes we may issue, are, or will be, effectively subordinated to liabilities of our subsidiaries, including guaranty liabilities. Substantially all of our subsidiaries have guaranteed our revolving credit facility and term loan; none of our subsidiaries guaranty our outstanding notes. In addition, as of December 31, 2011, our subsidiaries had $632.3 million of secured debt. Our outstanding notes are, and any notes we may issue will be, effectively subordinated to any secured debt with regard to our assets pledged to secure those debts.

Our notes may permit redemption before maturity, and our noteholders may be unable to reinvest proceeds at the same or a higher rate.

        The terms of our notes may permit us to redeem all or a portion of our outstanding notes after a certain amount of time, or up to a certain percentage of the notes prior to certain dates. Generally, the redemption price will equal the principal amount being redeemed, plus accrued interest to the redemption date, plus any applicable premium. If a redemption occurs, our noteholders may be unable to reinvest the money they receive in the redemption at a rate that is equal to or higher than the rate of return on the applicable notes.

There may be no public market for notes we may issue and one may not develop.

        Generally, any notes we may issue will be a new issue for which no trading market currently exists. We may not list our notes on any securities exchange or seek approval for price quotations to be made available through any automated quotation system. There is no assurance that an active trading market for any of our notes will exist in the future. Even if a market develops, the liquidity of the trading market for any of our notes and the market price quoted for any such notes may be adversely affected by changes in the overall market for fixed income securities, by changes in our financial performance or prospects, or by changes in the prospects for REITs or for the real estate industry generally.

Conversion of our series D preferred shares will dilute the ownership interests of existing shareholders.

        The conversion of some or all of our series D preferred shares, including a conversion upon exercise of a "fundamental change" (as such term is defined in the applicable articles supplementary), will dilute the ownership interests of existing shareholders. Any sales in the public market of the common shares issuable upon such conversion could adversely affect prevailing market prices of our common shares. In addition, the existence of the series D preferred shares may encourage short selling

47


Table of Contents

by market participants because the conversion of the series D preferred shares could depress the price of our common shares or for other reasons.

There is no assurance that we will continue to make distributions.

        We intend to continue to pay regular quarterly distributions to our shareholders. However:

        For these reasons, among others, our distribution rate may decline or we may cease making distributions.

Rating agency downgrades may increase our cost of capital.

        Both our senior notes and our preferred stock are rated by two rating agencies. These rating agencies may elect to downgrade their ratings on our senior notes and our preferred stock at any time. Such downgrades may negatively affect our access to the capital markets and increase our cost of capital, including the interest rate and fees payable under our revolving credit facility and term loan agreements.

Risks Related to Investing in Foreign Countries

We are subject to social, political and economic risks of doing business in other countries.

        We conduct a portion of our business in Australia since our acquisition in October 2010 of CWH Australia Trust, formerly known as MacarthurCook Industrial Property Fund, an Australian listed property trust that owned at the time ten industrial properties. We also acquired an office property in Sydney, Australia in December 2010. As of December 31, 2011, we owned 11 properties with 1.8 million square feet in various locations in Australia. Circumstances and developments related to these international operations that could negatively affect our business, financial condition or results of operations include, but are not limited to, the following factors:

48


Table of Contents

        Although we have committed significant resources to manage our Australian business activities, if we are unable to successfully manage the risks associated with our foreign business, our non-U.S. investments could produce losses.

The depreciation in the value of the foreign currency in countries where we have a significant investment may adversely affect our results of operations and financial position.

        We have pursued, and may continue to pursue, growth opportunities in Australia where the U.S. dollar is not the national currency. At December 31, 2011, approximately 4.6% of our total assets were invested in Australian dollars, and we do not currently borrow in Australian dollars or enter currency derivative contracts to mitigate any foreign currency risk. As a result, we are subject to foreign currency risk due to potential fluctuations in exchange rates between the Australian and U.S. dollars. More specifically, a significant change in the value of the Australian dollar may have an adverse effect on our results of operations and financial position in the future. In the future, we may try to mitigate this foreign currency risk by borrowing under debt agreements denominated in Australian dollars and, on occasion and when deemed appropriate, using derivative contracts. However, we have no present intention to do so, and if we engage in such mitigation strategies, we cannot assure you that those attempts to mitigate foreign currency risk would be successful.

Item 2.    Properties.

        General.    At December 31, 2011, we had real estate investments totaling approximately $7.2 billion in 516 properties that were leased to approximately 2,000 tenants. Our properties are located in both central business district, or CBD, areas and suburban areas. We have concentrations of properties in six major geographic segments: Metro Philadelphia, PA; Oahu, HI; Metro Chicago, IL; Metro Denver, CO; Australia and Metro Washington, DC. For further information by geographic segment, see Note 12 to our consolidated financial statements included in "Exhibits and Financial Statement Schedules" of this Annual Report on Form 10-K.

        The closing price of our common shares on the NYSE on February 15, 2012, was $20.61 per share. The share prices in the tables above for the periods prior to July 1, 2010, are adjusted to give effect to the one for four combination of our common shares that was effective on July 1, 2010.

        As of February 15, 2012, there were approximately 1,790 shareholders of record, and we estimate that as of such date there were approximately 64,000 beneficial owners of our common shares.

        In July 2010, we declared a new quarterly common share dividend rate of $0.50 per share ($2.00 per share per year). Information about distributions paid to common shareholders is summarized in the table below and reflects the one for four combination of our common shares effective July 1, 2010.

All common share distributions shown in the table above have been paid in cash. We currently intend to continue to declare and pay common share distributions on a quarterly basis in cash. However, the amount and form of distributions are made at the discretion of our Board of Trustees and will depend upon various factors that our Board of Trustees deems relevant, including, but not limited to, requirements to maintain our status as a REIT, limitations in our revolving credit facility, term loan and public debt covenants, the availability of debt and equity capital to us, our Normalized FFO, and our expectation of our future capital requirements and operating performance. Therefore, there can be no assurance that we will continue to pay distributions in the future in cash or that the amount of any distributions we do pay will not decrease.

Item 7.    Management's Discussion and Analysis of Financial Condition and Results of Operations.

        The following discussion should be read in conjunction with our consolidated financial statements and accompanying notes included elsewhere in this Annual Report on Form 10-K.

OVERVIEW

        We primarily own office and industrial buildings in CBD and suburban locations throughout the United States. We also own 17.9 million square feet of leased industrial and commercial lands located in Oahu, Hawaii and 1.8 million square feet of office and industrial buildings located in Australia.

Property Operations

        As of December 31, 2011, 84.6% of our total square feet was leased, compared to 85.7% leased as of December 31, 2010. These results reflect a 2.1 percentage point decrease in occupancy at properties we owned continuously since January 1, 2010, partially offset by property acquisitions. Occupancy data for 2011 and 2010 is as follows (square feet in thousands):

Based on properties owned continuously since January 1, 2010.

(2)
Includes 27 properties with approximately 2,881 square feet which were reclassified to continuing operations from discontinued operations during the fourth quarter of 2011. Excludes properties sold in 2011.

(3)
Percent leased includes (i) space being fitted out for occupancy pursuant to existing leases and (ii) space which is leased, but is not occupied or is being offered for sublease by tenants.

        The average effective rental rate per square foot, as defined below, for our properties for the years ended December 31, 2011 and 2010 are as follows:

 
  Year Ended
December 31,
 
 
  2011   2010  

Average annualized effective rent per square foot(1)

  $ 15.69   $ 14.18  

(1)
Average annualized effective rental rate per square foot represents total rental income during the period specified divided by the average rentable square feet occupied during the period specified.

        During the year ended December 31, 2011, we renewed leases for 3.9 million square feet and entered new leases for 2.9 million square feet, at weighted average rental rates that were 2% above rents previously charged for the same space. The average lease term for leases entered during 2011 was 7.0 years. Commitments for tenant improvement and leasing costs for leases entered during 2011 totaled $104.8 million, or $15.40 per square foot on average (approximately $2.20/sq. ft. per year of the lease term).

        During the past twelve months, leasing market conditions in the majority of our markets appear to be stabilizing but remain weak. As a result, leasing activity within our portfolio is slow and our

54


Table of Contents

occupancy is declining slowly. Required landlord funded tenant build outs and leasing commissions payable by landlords to tenant brokers for new leases and lease renewals have increased in certain markets since 2008. These build out costs and leasing commissions are generally amortized during the terms of the affected leases. We believe that the current high unemployment rate and weak leasing market conditions in the U.S. may lead to a continued decrease in occupancy and effective rents, or gross rents less amortization of landlord funded tenant improvements and leasing costs, at our properties through the majority of 2012, but we expect our occupancy may begin to improve in late 2012 and 2013. However, there are too many variables for us to reasonably project what the financial impact of changing market conditions will be on our occupancy or financial results for future periods.

        We review all of our long lived assets used in operations for possible impairments following the end of each quarter and when there is an event or change in circumstances that indicates an impairment in value may have occurred. During 2011, we determined the carrying value of 26 properties exceeded their estimated fair value based on broker valuations and an analysis of property level cash flows, resulting in impairment charges aggregating $10.4 million.

        As of December 31, 2011, approximately 19.6% of our leased square feet and 21.3% of our annualized rents, determined as set forth below, are included in leases scheduled to expire through December 31, 2013. Lease renewals and rental rates at which available space may be relet in the future will depend on prevailing market conditions at the times these renewals are negotiated. Lease expirations by year, as of December 31, 2011, are as follows (square feet and dollars in thousands):

Investment Activities

        Since January 1, 2011, we have acquired 24 office properties with a combined 7,813,189 square feet for an aggregate purchase price of $1.3 billion, including the assumption of $469.1 million of mortgage debt and excluding closing costs. At the time of acquisition, these properties were 92.0% leased for a weighted average (by rents) term of 7.8 years and at rents which yielded approximately 9.0% of the aggregate gross purchase price, based on estimated annual NOI, which we define as U.S. generally accepted accounting principles, or GAAP, rental income less property operating expenses, on the date of closing.

        Since January 1, 2011, we have sold 20 office and industrial properties with a combined 2,148,000 square feet for $265.1 million, excluding closing costs, and recognized net gains of approximately $42.8 million. Included in these sales were two portfolio transactions involving a related person:

56


Table of Contents

        In July 2011, GOV issued 6,500,000 common shares in a public offering for $25.40 per common share, raising net proceeds of approximately $157.9 million. As a result of the per share sales price of this transaction being above our per share carrying value, our ownership percentage in GOV was reduced from 24.6% prior to this transaction to 21.1% after this transaction and we recognized a gain of $11.2 million.

        On December 22, 2011, our wholly owned subsidiary, SIR, filed a registration statement with the SEC for an IPO of common shares as a REIT that is focused on owning and investing in net leased, single tenant properties. If the SIR registration statement becomes effective and the IPO is completed, we expect to continue to own a majority of SIR's common shares after the completion of the offering and because of our retained majority interest in SIR, we expect SIR will remain one of our consolidated subsidiaries. On February 16, 2012, we transferred 251 properties (approximately 21,400,000 rentable square feet) to SIR, including substantially all of our commercial and industrial properties located in Oahu, HI and 23 suburban office and industrial properties located throughout the mainland U.S. In exchange for our contribution of 251 properties to SIR, we received 22,000,000 SIR common shares and a $400.0 million demand promissory note, or the Demand Note. We expect that SIR would use net proceeds of its proposed IPO to repay in part amounts outstanding under the Demand Note. Upon completion of the IPO, SIR expects to enter into a $500.0 million bank facility with a group of commercial banks. Upon completion of the IPO, SIR intends to borrow under the bank facility to repay the balance of the Demand Note and reimburse us for the costs we incurred in organizing SIR, establishing its bank facility and preparing for its IPO. There can be no assurance that SIR will be successful in completing its share offering and establishing the bank facility or that it will have the funds to repay the Demand Note or to reimburse us for the costs we incurred in organizing SIR.

        In order to govern the separation of SIR from us, upon completion of the IPO, we intend to enter into a transaction agreement with SIR. We expect that the transaction agreement will provide, among other things, that (1) the current assets and liabilities of the properties to be transferred to SIR will, as of the time of the closing of the IPO of SIR's common shares, be settled between us and SIR so that we will retain all pre-closing current assets and liabilities and SIR will assume all post-closing current assets and liabilities and (2) SIR will indemnify us with respect to any liability relating to any property transferred to it by us, including any liability which relates to periods prior to SIR's formation.

        Our two Managing Trustees, Mr. Barry Portnoy and Mr. Adam Portnoy, are also trustees of SIR, and Mr. John Popeo, our Treasurer and Chief Financial Officer, also serves as the Treasurer and Chief Financial Officer of SIR. In addition, if the IPO is completed, it is currently expected that Mr. William Lamkin, one of our Independent Trustees, will serve as an independent trustee of SIR.

        If the SIR IPO is completed, we also expect that RMR will provide business and property management services to SIR. We expect that SIR will enter into management agreements with RMR which are on terms that are substantially similar to our management agreements with RMR. Accordingly, our management fees to RMR may be reduced by the amount of the management fees that would have otherwise been payable by us with respect to properties contributed by us to SIR. The

57


Table of Contents

SIR IPO will not occur unless, among other things, the SEC has declared the registration statement to be effective and underwriters have agreed to purchase and distribute the shares proposed to be offered by SIR. In addition, we may determine in our discretion, due to market conditions or otherwise, not to proceed with the SIR IPO. Accordingly, there can be no assurance that the IPO will occur.

Financing Activities

        In March 2011, we repaid at maturity all $168.2 million of our floating rate senior notes using borrowings under our revolving credit facility. In June 2011, we repaid at maturity $29.2 million of 7.435% mortgage debt using cash on hand. In July 2011, we prepaid at par plus a premium $23.2 million of 8.05% mortgage debt due in 2012 using cash on hand and proceeds from our common share offering discussed below. In connection with the July prepayment, we recorded a net gain on early extinguishment of debt of $310,000 from the write off of unamortized premiums and deferred financing fees.

        In June 2011, we issued 11,000,000 series E cumulative redeemable preferred shares in a public offering, raising net proceeds of $265.4 million. Net proceeds from this offering were used to reduce amounts outstanding under our revolving credit facility.

        In July 2011, we issued 11,500,000 common shares in a public offering, raising net proceeds of $264.1 million. Net proceeds from this offering were used to repay amounts outstanding under our revolving credit facility and for general business purposes, including funding acquisitions.

        In October 2011, we amended our existing $750.0 million revolving credit facility to extend the maturity date from August 8, 2013 to October 19, 2015. The interest rate paid on drawings under the amended revolving credit facility was reduced from LIBOR plus 200 basis points to LIBOR plus 125 basis points, subject to adjustments based on changes to our credit ratings. In addition, our amended revolving credit facility includes a conditional option to extend the facility an additional year to October 19, 2016 and includes a feature under which maximum borrowings may be increased to up to $1.5 billion in certain circumstances. In connection with this amendment, we recorded a loss on early extinguishment of debt of $345,000 from the write off of unamortized deferred financing fees relating to lenders that did not commit to the amended terms.

        In October 2011, we amended our existing term loan and increased its size from $400.0 million to $557.0 million. Prior to this amendment, our term loan had a maturity date of December 15, 2015 and interest paid on drawings of LIBOR plus 200 basis points, subject to adjustments based on changes to our credit ratings. The amended term loan eliminates the prepayment premium, extends the maturity date to December 15, 2016, and reduces interest paid on drawings from LIBOR plus 200 basis points to LIBOR plus 150 basis points, subject to adjustments based on changes to our credit ratings. In addition, the amended term loan includes a feature under which maximum borrowings may be increased to up to $1.0 billion in certain circumstances. Three lenders representing $57.0 million of aggregate borrowings did not commit to the amended term loan. Accordingly, these three lenders will be subject to the terms of the old term loan and we have agreed to repay these lenders on December 16, 2012 when there will be no prepayment penalty.

        In January 2012, we prepaid at par all $150.7 million of our 6.95% senior notes due 2012, using cash on hand and borrowings under our revolving credit facility. In February 2012, we repaid at maturity $5.4 million of 7.31% mortgage debt using cash on hand.

We calculate FFO and Normalized FFO as shown above. FFO is calculated on the basis defined by The National Association of Real Estate Investment Trusts, or NAREIT, which is net income, calculated in accordance with GAAP, excluding gain or loss on sale of properties, plus real estate depreciation and amortization, loss on asset impairment and FFO from equity investees. Our calculation of Normalized FFO differs from NAREIT's definition of FFO because we exclude acquisition related costs, gains from issuance of shares by equity investees, gain and loss on early

        Rental income.    Rental income increased for the year ended December 31, 2010, compared to the same period in 2009, primarily due to an increase in rental income from our Metro Denver, CO, Metro Chicago, IL, Australia and Other Markets segments, partially offset by a decrease in rental income from our Metro Washington, DC segment, as described in the segment information in Note 12 to the notes to our consolidated financial statements of this Annual Report on Form 10-K. The aggregate increase primarily reflects the acquisition of 48 properties in 2009 and 2010, partially offset by a decrease in rental income from the contribution of 29 properties to GOV in 2009, the sale of 15 properties to GOV in 2010 and the decline in occupancy in 2010. Rental income from our Metro Denver, CO segment increased by $14.2 million, or 50.8%, primarily reflecting the acquisition of two properties in 2009 and 2010, partially offset by the contribution of three properties to GOV in June

Table of Contents

2009. Rental income from our Metro Chicago, IL segment increased by $2.4 million, or 17.4%, primarily reflecting the acquisition of two properties in 2010. Rental income from our Australia segment totaling $3.5 million reflects our acquisition of 11 properties during the fourth quarter of 2010. Rental income from our Other Markets segment increased $9.3 million, or 2.0%, primarily reflecting the acquisition of 29 properties during 2009 and 2010, offset by a $28.8 million decrease in rental income resulting from the contribution of 22 properties to GOV in June 2009 and the sale of 13 properties to GOV in 2010, and the decline in occupancy primarily from properties we owned continuously since January 1, 2009. Rental income from our Metro Washington, DC segment decreased by $12.9 million, or 22.0%, primarily reflecting the contribution of four properties to GOV in June 2009 and the sale of two properties to GOV in 2010, partially offset by an increase in rental income from two properties acquired during 2009 and two properties acquired during 2010. Rental income includes non-cash straight line rent adjustments totaling $11.2 million in 2010 and $12.2 million in 2009 and reductions for amortization of acquired real estate leases and obligations totaling $6.9 million in 2010 and $9.2 million in 2009. Rental income also includes lease termination fees totaling $2.1 million in 2010 and $1.3 million in 2009.

        Total expenses.    The increase in total expenses primarily reflects the acquisition of properties during 2009 and 2010 and losses on asset impairment recorded during 2010 discussed below, partially offset by the contribution of 29 properties to GOV in June 2009 and the sale of 15 properties to GOV during 2010. The increase in depreciation and amortization is also attributable to accelerated depreciation of $25.0 million on eight properties taken out of service and razed in 2011. The increase in general and administrative expenses is also due to an increase in legal fees associated with our industrial and commercial land in Hawaii and other litigation costs. The increase in acquisition related costs reflects taxes and fees related to properties acquired in Australia during 2010.

        Interest and other income.    The increase in interest and other income in 2010 primarily reflects a $750,000 nonrefundable deposit that was forfeited by the buyer of one of our properties when the buyer was unable to meet its obligation to purchase the property in January 2010 and $376,000 of interest income from our investment in marketable pass through certificates redeemed in August 2010.

        Interest expense.    The increase in interest expense in 2010 primarily reflects the issuance of $250.0 million of 5.875% unsecured senior notes in 2010, $125.0 million of 7.50% unsecured senior notes and $175.0 million of mortgage debt with a current interest rate of 5.66% during 2009, offset by the repurchase and retirement of $109.5 million of our debt in 2009, the prepayment of $182.4 million of mortgage debt and the repayment of $30.0 million of 8.875% and $20.0 million of 8.625% unsecured senior notes in 2010.

        Loss on asset impairment in continuing operations.    The loss on asset impairment in 2010 reflects the write down to estimated fair value of four office properties that we sold to GOV totaling $21.5 million and six office properties and 24 industrial & other properties located in our Other Markets segment totaling $106.3 million. The loss on asset impairment in 2009 reflects the write down to estimated fair value of three office properties and three industrial & other properties located in our Other Markets segment.

        (Loss) gain on early extinguishment of debt.    The loss on early extinguishment of debt in 2010 reflects the write off of unamortized discounts and deferred financing fees associated with the prepayment of $182.4 million of mortgage debt in August 2010. The gain on early extinguishment of debt in 2009 relates to the repurchase and retirement of $31.8 million of our floating rate senior notes due in 2011 for $24.2 million, $49.3 million of our 6.95% senior notes due in 2012 for $41.5 million, $9.0 million of our 6.50% senior notes due in 2013 for $7.3 million, $5.3 million of our 5.75% senior notes due in 2014 for $4.3 million and $14.0 million of our 6.40% senior notes due in 2015 for $11.0 million, net of unamortized deferred financing fees and note discounts.

Table of Contents

        Equity in earnings of investees.    Equity in earnings of investees represents our proportionate share of earnings (loss) from AIC and from GOV. The increase in earnings of investees primarily reflects our ownership interest in GOV since its formation in June 2009.

        Gain on issuance of shares by an equity investee.    The gain on issuance of shares by an equity investee reflects the issuance of 9,775,000 common shares by GOV in January 2010 and the issuance of 9,200,000 common shares by GOV in August 2010 at prices above our per share carrying value.

        Gain on asset acquisition.    The gain on asset acquisition in 2010 represents the excess of the fair value of the assets we acquired when we purchased CWH Australia Trust over the price we paid.

        Income from discontinued operations.    Income from discontinued operations reflects operating results from 17 office properties and three industrial & other properties sold in 2011, 20 office properties and three industrial properties sold in 2010 and ten office properties sold in 2009. The properties contributed or sold to GOV are not considered discontinued operations because of our continuing ownership of GOV.

        Loss on asset impairment in discontinued operations.    The loss on asset impairment in discontinued operations in 2010 reflects the write down to estimated fair value of one industrial property located in our Other Markets segment that we sold during 2011. The loss on asset impairment in discontinued operations in 2009 reflects the write down to estimated fair value of one office property and one industrial property located in our Other Markets segment that we sold during 2010.

        Net gain on sale of properties from discontinued operations.    Net sales proceeds and net gains from the sale of 20 office properties and three industrial & other properties in 2010 were $374.4 million and $137.8 million, respectively. Net sales proceeds and gain from the sale of ten office properties in 2009 were $212.0 million and $79.1 million, respectively.

        Gain on sale of properties.    Net sales proceeds and gains from the sale of 15 office properties to GOV in 2010 were $229.4 million and $34.3 million, respectively.

        Net income and net income available for common shareholders.    The decrease in net income and net income available for common shareholders is due primarily to losses on asset impairment and accelerated depreciation in 2010, increase in acquisition related costs, gain on the early extinguishment of debt recognized in 2009, a decrease in rents resulting from the contribution of 29 properties to GOV in June 2009, a decrease in rents from properties sold in 2009 and 2010, an increase in interest expense and the decline in occupancy in 2010, partially offset by the net gain recognized on sales of properties and to the issuance of common shares by GOV, and income from acquisitions made during 2009 and 2010. Net income available for common shareholders is net income reduced by preferred distributions and the excess redemption price paid over the carrying value of our 83/4% series B preferred shares that we redeemed in October 2010.

        Our principal source of funds to pay operating expenses, debt obligations and distributions on our common and preferred shares is rental income from our properties and distributions from our equity investment in GOV. This flow of funds has historically been sufficient for us to pay our operating expenses, debt service and distributions to shareholders. We believe that our operating cash flow will be sufficient to meet our operating expenses, debt service and distribution payments on our shares for the next 12 months and for the foreseeable future thereafter. Our future cash flows from operating activities will depend primarily upon our:

        We believe that present leasing market conditions in the majority of areas where our properties are located may result in continued decreases in occupancies and effective rents, or gross rents less amortization of landlord funded tenant improvements and leasing costs, but we expect our occupancy may begin to improve in late 2012 and 2013. Also, volatility in energy costs may also cause our future operating costs to fluctuate; however, the impact of these fluctuations is expected to be largely offset by the pass throughs of operating costs to our tenants pursuant to lease terms. We generally do not purchase turnaround properties or properties which do not generate positive cash flows. Our future purchases of properties which generate positive cash flows cannot be accurately projected because such purchases depend upon available opportunities which come to our attention.

        Cash flows provided by (used in) operating, investing and financing activities were $263.3 million, ($623.9) million and $359.8 million, respectively, for the year ended December 31, 2011, and $252.1 million, ($353.5) million and $274.9 million, respectively, for the year ended December 31, 2010. Changes in all three categories between 2011 and 2010 are primarily related to property acquisitions, improvements and sales, borrowings and repayments on debt, net proceeds received from the issuance of preferred and common shares in excess of payments for redemptions of our shares during 2011 and 2010, and increased distributions on our common shares.

Our Investment and Financing Liquidity and Resources

        In order to fund acquisitions and to accommodate cash needs that may result from timing differences between our receipt of rents and our desire or need to make distributions or pay operating or capital expenses, we maintain a $750.0 million unsecured revolving credit facility with a group of institutional lenders. In October 2011, we amended this credit facility to extend the maturity date from August 8, 2013 to October 19, 2015, and to reduce interest paid on borrowings from LIBOR plus 200 basis points to LIBOR plus 125 basis points, subject to adjustments based on changes to our credit ratings. Our amended credit facility also provides us with the conditional option to extend the maturity date for one year to October 19, 2016 and includes a feature under which maximum borrowings may be increased to up to $1.5 billion in certain circumstances. At December 31, 2011, cash and cash equivalents totaled $192.8 million and $100.0 million was outstanding and $650.0 million was available under our revolving credit facility. On January 3, 2012, we prepaid all $150.7 million of our 6.95% senior notes due 2012 using cash on hand. We expect to use cash balances, borrowings under our credit facility, proceeds from the sale of properties, distributions from our equity investment in GOV and net proceeds from offerings of equity or debt securities to fund our continuing operations, debt repayments and future property acquisitions.

        As of February 22, 2012, $172.0 million was outstanding and $578.0 million was available under our revolving credit facility.

        In 2011, we paid common distributions totaling $150.1 million. We also paid an aggregate of $44.4 million of preferred distributions on our series B, series C, series D and series E preferred shares. In February 2012, we paid a common distribution of $41.9 million and preferred distributions aggregating $13.8 million. We funded these distributions using cash on hand and borrowings under our revolving credit facility.

We have a mortgage loan for $175.0 million secured by one property located in Philadelphia, PA that matures in 2019. Interest on this loan is payable at a spread over LIBOR but has been fixed for the first seven years with a cash flow hedge that sets the rate at approximately 5.66% per year.

Total debt as of December 31, 2011, net of unamortized premiums and discounts, equals $3,577,331.

        In March 2011, we repaid at maturity all $168.2 million of our floating rate senior notes using borrowings under our revolving credit facility. In June 2011, we repaid at maturity $29.2 million of 7.435% mortgage debt using cash on hand. In July 2011, we prepaid at par plus a premium $23.2 million of 8.05% mortgage debt due in 2012 using cash on hand and proceeds from our common share offering completed in July discussed below. We recorded a net gain on early extinguishment of debt of $310,000 from the write off of unamortized premiums and deferred financing fees related to this mortgage.

        In June 2011, we issued 11,000,000 series E cumulative redeemable preferred shares in a public offering, raising net proceeds of $265.4 million. In July 2011, we issued 11,500,000 common shares in a public offering, raising net proceeds of approximately $264.1 million. Net proceeds from these offerings were used to repay amounts outstanding under our revolving credit facility and for general business purposes, including funding acquisitions and repaying debt.

        When significant amounts are outstanding under our revolving credit facility, or as the maturity dates of our revolving credit facility and term debts approach, we explore alternatives for the repayment of amounts due. Such alternatives may include incurring additional debt and issuing new equity securities. We have an effective shelf registration statement that allows us to issue public securities on an expedited basis, but it does not assure that there will be buyers for such securities.

        We believe we will have access to various types of financings, including debt or equity offerings, to fund our future acquisitions and to pay our debts and other obligations as they become due. The

completion and the costs of our future debt transactions will depend primarily upon market conditions and our credit ratings. We have no control over market conditions. Our credit ratings depend upon evaluations by credit rating agencies of our business practices and plans and, in particular, whether we appear to have the ability to maintain our earnings, to space our debt maturities and to balance our use of debt and equity capital so that our financial performance and leverage ratios afford us flexibility to withstand any reasonably anticipatable adverse changes. We intend to conduct our business activities in a manner which will continue to afford us reasonable access to capital for investment and financing activities. However, there can be no assurance that we will be able to complete any debt or equity offerings or that our cost of any future public or private financings will not increase.

        During the year ended December 31, 2011, we received cash distributions totaling $16.6 million from GOV. At December 31, 2011, we owned 9,950,000, or 21.1%, of the common shares of beneficial interest of GOV with a carrying value of $172.2 million and a market value, based on quoted market prices, of $224.4 million ($22.55 per share). In July 2011, GOV issued 6,500,000 common shares in a public offering for $25.40 per common share, raising net proceeds of approximately $157.9 million. As a result of the per share sales price of this transaction being above our per share carrying value, our ownership percentage in GOV was reduced from 24.6% prior to this transaction to 21.1% after this transaction, and we recognized a gain of $11.2 million.

        During 2011, we acquired 23 properties with a combined 6,806,615 square feet for an aggregate purchase price of $1.1 billion, including the assumption of $321.2 million of mortgage debt and excluding closing costs, using cash on hand, borrowings under our revolving credit facility and proceeds from property sales and equity offerings. Since January 1, 2012, we have acquired an additional property with 1,006,574 square feet for a purchase price of $150.6 million, including the assumption of $147.9 million of mortgage debt and excluding closing costs. We also have entered into agreements to acquire two properties with a combined 1,056,869 square feet for an aggregate purchase price of $148.0 million, including the assumption of approximately $29.2 million of mortgage debt and excluding closing costs. Details of these transactions are as follows:

This property is 99% leased to nine tenants for a weighted (by rents) average lease term of 4.3 years. The purchase price is $49.0 million, including the assumption of approximately $29.2 million of mortgage debt and excluding closing costs. We expect to acquire this property during the first half of 2012; however, this acquisition is subject to customary closing conditions, including the assumption of existing mortgage debt, and we can provide no assurance that we will acquire this property in that time period or at all.

Property Sales:

        In November 2010, we entered into various purchase and sale agreements to sell 27 properties which are majority leased as medical office, clinic and biotech laboratory buildings to SNH for an aggregate sale price of $470.0 million, excluding closing costs. In 2010, we sold 21 of these properties containing approximately 2,066,000 square feet for $374.1 million, excluding closing costs, and recognized net gains totaling $133.3 million. In January 2011, we sold the remaining six properties containing approximately 737,000 square feet for an aggregate sale price of $95.9 million, excluding closing costs, and we recognized gains totaling $35.0 million.

At the conclusion of these transactions, substantially all of the properties that we leased to tenants in

medical related businesses were sold to SNH and the existing right of first refusal between us and SNH terminated. Because we and SNH have three trustees in common and we are both managed by RMR, the terms of these transactions were negotiated and approved by special committees of our and SNH's boards of trustees composed solely of Independent Trustees who were not also Independent Trustees of both companies.

        In February 2011, we sold an industrial property located in Adairsville, GA, with 101,400 square feet for $2.3 million, excluding closing costs, and recognized a loss of $94,000.

        During the fourth quarter of 2011, we reclassified to continuing operations 27 properties previously classified as held for sale, and previously included in discontinued operations, when we determined that the sale of these properties was no longer probable. As of December 31, 2011, none of our properties was classified as held for sale.

        During the year ended December 31, 2011 and 2010, cash expenditures made and capitalized for tenant improvements, leasing costs, building improvements and development and redevelopment activities were as follows (amounts in thousands):

Off Balance Sheet Arrangements

        As of December 31, 2011, we had no off balance sheet arrangements that have had or are reasonably likely to have a current or future material effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources. We have no commercial paper, swaps or hedges as of December 31, 2011, other than the cash flow hedge on a $175.0 million mortgage loan described in Note 11 to the notes to our consolidated financial statements and under "Our Investment and Financing Liquidity and Resources" of this Annual Report on Form 10-K.

Debt Covenants

        Our principal unsecured debt obligations at December 31, 2011, were our unsecured revolving credit facility, our unsecured term loan, and our $2.3 billion of publicly issued unsecured term debt. Our publicly issued debt is governed by an indenture. Our public debt indenture and related supplements and our revolving credit facility and term loan agreements contain a number of financial ratio covenants which generally restrict our ability to incur debts, including debts secured by mortgages on our properties, in excess of calculated amounts, require us to maintain a minimum net worth, restrict our ability to make distributions under certain circumstances and require us to maintain other financial ratios. At December 31, 2011, we believe we were in compliance with all of our covenants under our indenture and related supplements and our revolving credit facility and term loan agreements.

        In addition to our unsecured debt obligations, we had $632.3 million (net of discounts) of mortgage notes outstanding at December 31, 2011.

73


Table of Contents

        None of our indenture and related supplements, our revolving credit facility, our term loan agreement or our mortgage notes contains provisions for acceleration or requires us to provide collateral security which could be triggered by our debt ratings. However, our senior debt rating is used to determine the interest rate and the fees payable under our revolving credit facility and our term loan agreement.

        Our public debt indenture and related supplements contain cross default provisions, which are generally triggered upon default of any of our other debts of $20.0 million or more. Similarly, our revolving credit facility and term loan agreement contain cross default provisions. A termination of our business management agreement with RMR would cause a default under our revolving credit facility and term loan, if not approved by a majority of our lenders.

Related Person Transactions

        We have relationships among us, our Trustees, our executive officers, RMR, SNH, GOV, SIR, AIC and other companies to which RMR provides management services and others affiliated with or related to them. For example, we have no employees; personnel and various services we require to operate our business are provided to us by RMR pursuant to management agreements. Also, as a further example, we have relationships with other companies to which RMR provides management services and which have trustees, directors and officers who are also Trustees, directors or officers of ours or RMR, including SNH, which is our former subsidiary and with which we have engaged in transactions from time to time, including our selling medical office, clinic and biotech laboratory buildings to SNH; GOV, which is also our former subsidiary, of which we are the largest shareholder and to which we have previously sold properties that are majority leased to government tenants; SIR, which is currently a wholly owned subsidiary of ours that has filed a registration statement with the SEC for an IPO of common shares and to which we have transferred 251 properties; and AIC, an Indiana insurance company, which we, RMR, SNH, GOV, HPT, Five Star and TA each currently own approximately 14.3% of, and with respect to which we and the other shareholders of AIC have property insurance in place providing $500.0 million of coverage pursuant to an insurance program arranged by AIC and with respect to which AIC is a reinsurer of certain coverage amounts. For further information about these and other such relationships and related person transactions and about the risks which may arise as a result of those and other related person transactions and relationships, please see Note 9 to the notes to our consolidated financial statements included in Item 15 of this Annual Report on Form 10-K, which is incorporated herein by reference. In addition, for more information about these transactions and relationships, please see elsewhere in this report, including "Warning Concerning Forward Looking Statements" and the "Risk Factors" section for a description of risks which may arise from these transactions and relationships. Descriptions of our agreements with RMR, SNH, GOV, SIR and AIC in this Annual Report on Form 10-K are summaries and are qualified in their entirety by the terms of the agreements which are among the exhibits listed in Item 15 of this Annual Report on Form 10-K and incorporated herein by reference. In addition, copies of certain of those agreements are filed with the SEC and may be obtained from the SEC's website at www.sec.gov.

        We believe that our agreements with RMR, SNH, GOV, SIR and AIC are on commercially reasonable terms. We also believe that our relationships with RMR, SNH, GOV, SIR and AIC and their affiliated and related persons and entities benefit us, and, in fact, provide us with competitive advantages in operating and growing our business.

Critical Accounting Policies

        Our critical accounting policies are those that will have the most impact on the reporting of our financial condition and results of operations and those requiring significant judgments and estimates. We believe that our judgments and estimates are consistently applied and produce financial information

74


Table of Contents

that fairly presents our results of operations. Our most critical accounting policies involve our investments in real property. These policies affect our:

        We allocate the consideration paid, generally cash plus the fair value of any assumed liabilities, among land, building and improvements and identified intangible assets and liabilities, consisting of the value of above market and below market leases, the value of acquired in place leases and the value of tenant relationships. Purchase price allocations and the determination of useful lives are based on our estimates and, under some circumstances, studies from independent real estate appraisal firms to provide market information and evaluations that are relevant to our purchase price allocations and determinations of useful lives; however, we are ultimately responsible for the purchase price allocations and determination of useful lives.

        We allocate the consideration to land, building and improvements based on a determination of the relative fair values of these assets assuming the property is vacant. We determine the fair value of a property using methods that we believe are similar to those used by independent appraisers. Purchase price allocations to above market and below market leases are based on the estimated present value (using an interest rate which reflects our assessment of the risks associated with the leases acquired) of the difference between (1) the contractual amounts to be paid pursuant to the acquired in place leases and (2) our estimate of fair market lease rates for the corresponding leases, measured over a period equal to the remaining non-cancelable terms of the respective leases. Purchase price allocations to acquired in place leases and tenant relationships are determined as the excess of (1) the purchase price paid for a property after adjusting existing acquired in place leases to estimated market rental rates over (2) the estimated fair value of the property as if vacant. We aggregate this value between acquired in place lease values and tenant relationships based on our evaluation of the specific characteristics of each tenant's lease; however, the value of tenant relationships has not been separated from acquired in place lease value for our properties because we believe such value and related amortization expense is immaterial for acquisitions reflected in our historical financial statements. We consider certain factors in performing these analyses including estimates of carrying costs during the expected lease up periods, including real estate taxes, insurance and other operating income and expenses and costs to execute similar leases in current market conditions, such as leasing commissions, legal and other related costs. If we believe the value of tenant relationships is material in the future, those amounts will be separately allocated and amortized over the estimated lives of the relationships. We recognize the excess, if any, of the consideration paid over amounts allocated to land, building and improvements and identified intangible assets and liabilities as goodwill and we recognize gains if amounts allocated exceed the consideration paid.

        We compute depreciation expense using the straight line method over estimated useful lives of up to 40 years for buildings and improvements and up to 12 years for personal property. We do not depreciate the allocated cost of land. We amortize capitalized above market lease values (included in acquired real estate leases) as a reduction to rental income over the remaining non-cancelable terms of the respective leases. We amortize capitalized below market lease values (presented as assumed real estate lease obligations) as an increase to rental income over the remaining terms of the respective leases. We amortize the value of acquired in place leases exclusive of the value of above market and below market in place leases to expense over the remaining non-cancelable periods of the respective leases. If a lease is terminated prior to its stated expiration, all unamortized amounts relating to that

lease are written off. Purchase price allocations require us to make certain assumptions and estimates. Incorrect assumptions and estimates may result in inaccurate depreciation and amortization charges over future periods.

        We periodically evaluate our properties for possible impairments. Impairment indicators may include declining tenant occupancy, lack of progress releasing vacant space, tenant bankruptcies, low long term prospects for improvement in property performance, weak or declining tenant profitability, cash flow or liquidity, our decision to dispose of an asset before the end of its estimated useful life and legislative, market or industry changes that could permanently reduce the value of a property. If indicators of impairment are present, we evaluate the carrying value of the related property by comparing it to the expected future undiscounted cash flows to be generated from that property. If the sum of these expected future cash flows is less than the carrying value, we reduce the net carrying value of the property to its estimated fair value. This analysis requires us to judge whether indicators of impairment exist and to estimate likely future cash flows. If we misjudge or estimate incorrectly or if future tenant operations, market or industry factors differ from our expectations we may record an impairment charge that is inappropriate or fail to record a charge when we should have done so, or the amount of any such charges may be inaccurate.

        Each time we enter a new lease or materially modify an existing lease we evaluate its classification as either a capital or operating lease. The classification of a lease as capital or operating affects the carrying value of a property, as well as our recognition of rental payments as revenue. These evaluations require us to make estimates of, among other things, the remaining useful life and fair market value of a leased property, appropriate discount rates and future cash flows. Incorrect assumptions or estimates may result in misclassification of our leases.

        These policies involve significant judgments made based upon experience, including judgments about current valuations, ultimate realizable value, estimated useful lives, salvage or residual value, the ability and willingness of our tenants to perform their obligations to us, current and future economic conditions and competitive factors in the markets in which our properties are located. Competition, economic conditions and other factors may cause occupancy declines in the future. In the future, we may need to revise our carrying value assessments to incorporate information which is not now known, and such revisions could increase or decrease our depreciation expense related to properties we own, result in the classification of our leases as other than operating leases or decrease the carrying values of our assets.

        Our investments in GOV and AIC are accounted for using the equity method of accounting. Under the equity method, we record our percentage share of net earnings from GOV and AIC in our consolidated statements of income. We use the income statement method to account for issuance of common shares of beneficial interest by GOV and shares of common stock by AIC. Under this method, gains and losses reflecting changes in the value of our investments at the date of issuance of additional common shares by GOV or AIC are recognized in our consolidated statements of income. Under the equity method, accounting policy judgments made by GOV and AIC could have a material effect on our net income. Also, if we determine there is an "other than temporary" decline in the fair value of these investments, their cost basis would be written down to fair value and the amount of the write down would be included in our earnings. In evaluating the fair value of these investments, we have considered, among other things, quoted market prices for GOV, the financial condition and near term prospects of each investee, earnings trends, asset quality, asset valuation models, and the financial condition and prospects for their respective industries generally.

IMPACT OF INFLATION

        Inflation might have both positive and negative impacts upon us. Inflation might cause the value of our real estate to increase. Inflation might also cause our costs of equity and debt capital and other operating costs to increase. An increase in our capital costs or in our operating costs will result in decreased earnings unless it is offset by increased revenues.

Table of Contents

        To mitigate the adverse impact of increased costs of debt capital in the event of material inflation, we may enter into additional interest rate hedge arrangements in the future. The decision to enter into these agreements will be based on various factors, including the amount of our floating rate debt outstanding, our belief that material interest rate increases are likely to occur, the costs of and our expected benefit from these agreements, and upon requirements of our borrowing arrangements.

        In periods of rapid inflation, our tenants' operating costs may increase faster than revenues and this fact may have an adverse impact upon us if our tenants' operating income becomes insufficient to pay our rent. To mitigate the adverse impact of tenant financial distress upon us, we require some of our tenants to provide guarantees or security for our rent.

IMPACT OF CLIMATE CHANGE

        The current political debate about climate change has resulted in various treaties, laws and regulations which are intended to limit carbon emissions. We believe these laws being enacted or proposed may cause energy costs at our properties to increase, but we do not expect the direct impact of these increases to be material to our results of operations because the increased costs either would be the responsibility of our tenants directly or in large part may be passed through by us to our tenants as additional lease payments. Although we do not believe it is likely in the foreseeable future, laws enacted to mitigate climate change may make some of our buildings obsolete or cause us to make material investments in our properties which could materially and adversely affect our financial condition.

Item 7A.    Quantitative and Qualitative Disclosures About Market Risk.

        We are exposed to risks associated with market changes in interest rates and foreign-exchange related variability on our investments in Australia.

Interest Rate Risk

        We manage our exposure to interest rate risk by monitoring available financing alternatives. Our strategy to manage exposure to changes in interest rates is unchanged from December 31, 2010. Other than as described below, we do not foresee any significant changes in our exposure to fluctuations in interest rates or in how we manage this exposure in the near future.

        At December 31, 2011, our total outstanding fixed rate term debt consisted of the following fixed rate notes:

These notes were prepaid at par in January 2012.

(2)
These notes were repaid at maturity in February 2012.

(3)
Interest on this loan is payable at a spread over LIBOR but has been fixed for the first seven years to 2016 by a cash flow hedge which sets the rate at approximately 5.66%. The coupon rate represents the floating interest rate at December 31, 2011.

        At December 31, 2011, our secured notes are collateralized by 23 of our properties and require principal and interest payments through maturity pursuant to amortization schedules.

        We have interest rate swap agreements to manage our interest rate risk exposure on $175.0 million of mortgage notes due 2019, which require interest at a spread over LIBOR. The interest rate swap agreements utilized by us effectively modify our exposure to interest rate risk arising from this floating rate mortgage loan by converting this floating rate debt to a fixed rate through December 1, 2016, thus reducing the impact of interest rate changes on future interest expense. These agreements involve the receipt of floating rate amounts in exchange for fixed rate interest payments over the life of the agreements. Approximately 4.9% ($175.0 million) of our total outstanding debt had interest payments designated as hedged transactions to interest rate swap agreements at December 31, 2011. As of December 31, 2011, the fair value of our derivative instruments included in accounts payable and accrued expenses and accumulated other comprehensive loss in our consolidated balance sheet totaled $15.8 million.

        Because our fixed rate unsecured and secured notes bear interest at fixed rates, changes in market interest rates during the term of these debts will not affect our operating results. If all of our fixed rate unsecured and secured notes outstanding at December 31, 2011, were to be refinanced at interest rates which are 10% higher or lower than shown above, our per annum interest cost would increase or decrease, respectively, by approximately $18.0 million.

        Changes in market interest rates would affect the fair value of our fixed rate debt obligations; increases in market interest rates decrease the fair value of our fixed rate debt, while decreases in market interest rates increase the value of our fixed rate debt. Based on the balances outstanding at December 31, 2011, and discounted cash flow analyses, a hypothetical immediate 10% change in

Table of Contents

interest rates would change the fair value of our fixed rate unsecured and secured debt obligations by approximately $55.0 million.

        Each of our fixed rate unsecured and secured debt arrangements allows us to make repayments earlier than the stated maturity date. In some cases, we are not allowed to make early repayment prior to a cutoff date and in most cases we are allowed to make prepayments only at a premium equal to a make whole amount, as defined, generally designed to preserve a stated yield to the note holder. These prepayment rights may afford us the opportunity to mitigate the risk of refinancing at maturity at higher rates by refinancing prior to maturity. The majority of our fixed rate senior unsecured notes are publicly traded, and we have in the past and may in the future occasionally take advantage of market opportunities to repurchase notes which will also mitigate future refinancing risks.

        Although we have no present plans to do so, we may in the future enter into other hedge arrangements to mitigate our exposure to changes in interest rates.

        At December 31, 2011, $100.0 million was outstanding and $650.0 million was available for drawing under our unsecured revolving credit facility, and we had $557.0 million of floating rate term debt outstanding. Our revolving credit facility, as amended in October 2011, matures in October 2015 and includes a conditional option for us to extend the maturity by one year to October 2016. Repayments under our revolving credit facility may be made at any time without penalty. Our term loan was amended in October 2011 to increase borrowings to $557.0 million and to extend the maturity date to December 2016 for $500.0 million of the term loan. We agreed to repay on December 16, 2012 lenders representing $57.0 million who did not commit to amended terms. Repayments with respect to $500.0 million of our term loan may be made at any time without penalty. We borrow in U.S. dollars and borrowings under our revolving credit facility and our term loan require interest at LIBOR plus a premium. Accordingly, we are vulnerable to changes in U.S. dollar based short term rates, specifically LIBOR. The weighted average interest rate payable on our revolving credit facility and term loan was 2.1% during the year ended December 31, 2011. A change in interest rates would not affect the value of these floating rate unsecured debts but would affect our operating results. The following table presents the impact a 10% change in interest rates would have on our floating rate interest expense as of December 31, 2011 (dollars in thousands):

 
  Impact of Changes in Interest Rates  
 
  Interest Rate
Per Year
  Outstanding
Debt
  Total Interest
Expense
Per Year
 

At December 31, 2011

    2.10 % $ 657,000   $ 13,797  

10% reduction

    1.90 % $ 657,000   $ 12,483  

10% increase

    2.30 % $ 657,000   $ 15,111  

        The foregoing table shows the impact of an immediate change in floating interest rates. If interest rates were to change gradually over time, the impact would be spread over time. Our exposure to fluctuations in floating interest rates will increase or decrease in the future with increases or decreases in the outstanding amount of our revolving credit facility or other floating rate debt.

Foreign Currency Risk

        Foreign currency risk is the possibility that our financial results are affected by changes in currency exchange rates. Our primary exposure to foreign currency exchange rates relates to the translation of the operating results of our Australian subsidiary from Australian dollars into U.S. dollars. To mitigate our foreign currency exchange exposure in the future, depending on the relative significance of our business activities in Australia at that time, we may borrow in Australian currency. We also may use foreign currency derivative contracts to manage foreign currency exchange rate risk associated with the projected net operating income of our Australian operations. At December 31, 2011 and at

79


Table of Contents

February 22, 2012, we had no borrowings in Australian dollars and no derivative contracts outstanding and no present intention to borrow in Australian currency or otherwise to hedge our foreign currency risks. Accordingly, we may experience future fluctuations in our earnings as a result of changes in foreign currency exchange rates. A 10% change in foreign currency exchange rates used to convert our 2011 Australian operating results to U.S. dollars would not be material to our current year consolidated earnings.

Item 9A.    Controls and Procedures.

        As of the end of the period covered by this report, our management carried out an evaluation, under the supervision and with the participation of our Managing Trustees, our President and our Treasurer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures pursuant to Exchange Act Rules 13a-15 and 15d-15. Based upon that evaluation, our Managing Trustees, our President and our Treasurer and Chief Financial Officer concluded that our disclosure controls and procedures are effective.

        There have been no changes in our internal control over financial reporting during the quarter ended December 31, 2011, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Management Report on Assessment of Internal Control Over Financial Reporting

        We are responsible for establishing and maintaining adequate internal control over financial reporting. Our internal control system is designed to provide reasonable assurance to our management and Board of Trustees regarding the preparation and fair presentation of published financial statements. All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

        Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2011. In making this assessment, it used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control—Integrated Framework. Based on our assessment, we believe that, as of December 31, 2011, our internal control over financial reporting is effective.

        Ernst & Young LLP, the independent registered public accounting firm that audited our 2011 consolidated financial statements included in this Annual Report on Form 10-K, has issued an attestation report on our internal control over financial reporting. The report appears elsewhere herein.

Report of Independent Registered Public Accounting Firm

To the Trustees and Shareholders of CommonWealth REIT

        We have audited the accompanying consolidated balance sheets of CommonWealth REIT (the "Company") as of December 31, 2011 and 2010, and the related consolidated statements of income, shareholders' equity, and cash flows for each of the three years in the period ended December 31, 2011. Our audits also included the financial statement schedules listed in the Index at Item 15(a). These financial statements and schedules are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements and schedules based on our audits.

        We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

        In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of CommonWealth REIT at December 31, 2011 and 2010, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2011, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedules, when considered in relation to the basic financial statements taken as a whole, present fairly in all material respects the information set forth therein.

        We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), CommonWealth REIT's internal control over financial reporting as of December 31, 2011, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 27, 2012 expressed an unqualified opinion thereon.

Report of Independent Registered Public Accounting Firm

To the Trustees and Shareholders of CommonWealth REIT

        We have audited CommonWealth REIT's (the "Company") internal control over financial reporting as of December 31, 2011, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). CommonWealth REIT's management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management Report on Assessment of Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the company's internal control over financial reporting based on our audit.

        We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

        A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

        Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

        In our opinion, CommonWealth REIT maintained, in all material respects, effective internal control over financial reporting as of December 31, 2011, based on the COSO criteria.

        We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the 2011 consolidated financial statements of CommonWealth REIT and our report dated February 27, 2012 expressed an unqualified opinion thereon.

COMMONWEALTH REIT

Notes to Consolidated Financial Statements

(dollars in thousands, except per share data)

Note 1. Organization

        CommonWealth REIT is a real estate investment trust, or REIT, formed in 1986 under the laws of the State of Maryland. At December 31, 2011, we had investments in 516 primarily office and industrial properties with a total of approximately 72,283,000 square feet of leasable space, including 57 properties with approximately 17,896,000 square feet of leased industrial and commercial lands in Oahu, HI and 11 properties with approximately 1,756,000 square feet located in various locations in Australia. In addition, we owned 21.1% of the common shares of Government Properties Income Trust, or GOV, a Maryland REIT that primarily owns properties that are majority leased to government tenants. GOV was our wholly owned subsidiary until its initial public offering, or IPO, in June 2009 when it became a separate public entity.

Note 2. Summary of Significant Accounting Policies

        Basis of Presentation.    The consolidated financial statements include our investments in 100% owned subsidiaries. All intercompany transactions have been eliminated.

        We account for our investments in 50% or less owned companies, including our investments in GOV and Affiliates Insurance Company, or AIC, over which we can exercise influence, but do not control, using the equity method of accounting. Significant influence is present through common representation on the boards of trustees or directors of us and each of GOV and AIC. Our two Managing Trustees are also managing trustees of GOV and owners of Reit Management & Research LLC, or RMR, which is the manager of us, GOV and AIC, and each of our Trustees is a director of AIC. We use the income statement method to account for issuance of common shares of beneficial interest by GOV and shares of common stock by AIC. Under this method, gains and losses reflecting changes in the value of our investments at the date of issuance of additional common shares by GOV or AIC are recognized in our income statement.

        Real Estate Properties.    We record real estate properties at cost. We depreciate real estate investments on a straight line basis over estimated useful lives of up to 40 years for buildings and improvements, and up to 12 years for personal property.

        We allocate the consideration paid, generally cash plus the fair value of any assumed liabilities, for our properties among land, building and improvements and identified intangible assets and liabilities, consisting of the value of above market and below market leases, the value of acquired in place leases and the value of tenant relationships. Purchase price allocations and the determination of useful lives are based on our estimates and, under some circumstances, studies from independent real estate appraisal firms to provide market information and evaluations that are relevant to our purchase price allocations and determinations of useful lives; however, we are ultimately responsible for the purchase price allocations and determination of useful lives.

        We allocate the consideration to land, building and improvements based on a determination of the relative fair values of these assets assuming the property is vacant. We determine the fair value of a property using methods that we believe are similar to those used by independent appraisers. Purchase price allocations to above market and below market leases are based on the estimated present value (using an interest rate which reflects our assessment of the risks associated with the leases acquired) of the difference between (1) the contractual amounts to be paid pursuant to the acquired in place leases and (2) our estimate of fair market lease rates for the corresponding leases, measured over a period

equal to the remaining non-cancelable terms of the respective leases. Purchase price allocations to acquired in place leases and tenant relationships are determined as the excess of (1) the purchase price paid for a property after adjusting existing in place leases to estimated market rental rates over (2) the estimated fair value of the property as if vacant. We aggregate this value between acquired in place lease values and tenant relationships based on our evaluation of the specific characteristics of each tenant's lease; however, the value of tenant relationships has not been separated from acquired in place lease value for our properties because we believe such value and related amortization expense is immaterial for acquisitions reflected in our historical financial statements. We consider certain factors in performing these analyses including estimates of carrying costs during the expected lease up periods, including real estate taxes, insurance and other operating income and expenses and costs to execute similar leases in current market conditions, such as leasing commissions, legal and other related costs. If we believe the value of tenant relationships is material in the future, those amounts will be separately allocated and amortized over the estimated lives of the relationships. We recognize the excess, if any, of the consideration paid over amounts allocated to land, building and improvements and identified intangible assets and liabilities as goodwill and we recognize gains if amounts allocated exceed the consideration paid.

        We amortize capitalized above market lease values (presented in our consolidated balance sheets as acquired real estate leases) as a reduction to rental income over the remaining terms of the respective leases. We amortize capitalized below market lease values (presented in our consolidated balance sheets as assumed real estate lease obligations) as an increase to rental income over the remaining terms of the respective leases. Such amortization resulted in net reductions to rental income of $8,239, $6,895 and $9,162 during the years ended December 31, 2011, 2010 and 2009, respectively, and net reductions to income from discontinued operations of $241, $553 and $878, for the years ended December 31, 2011, 2010 and 2009, respectively. We amortize the value of acquired in place leases exclusive of the value of above market and below market acquired in place leases to expense over the remaining terms of the respective leases. The amount of such amortization included in depreciation and amortization totaled $39,102, $25,272 and $23,788 during the years ended December 31, 2011, 2010 and 2009, respectively. The amount of such amortization included in income from discontinued operations totaled $863, $1,311 and $1,346 during the years ended December 31, 2011, 2010 and 2009, respectively. If a lease is terminated prior to its stated expiration, the unamortized amount relating to that lease is written off.

        Capitalized above market lease values for properties held and used in operations were $173,909 and $140,506 as of December 31, 2011 and 2010, respectively, net of accumulated amortization of $51,578 and $55,685, respectively, as of those same respective dates. As of December 31, 2010, capitalized above market lease values and accumulated amortization for properties held for sale were $6,089 and $5,326, respectively. Capitalized below market lease values for properties held and used in operations were $101,039 and $90,483 as of December 31, 2011 and 2010, respectively, net of accumulated amortization of $30,860 and $24,543, respectively, as of those same respective dates. As of December 31, 2010, capitalized below market lease values and accumulated amortization for properties held for sale were $27 and $20, respectively. The value of acquired in place leases, exclusive of the value of above and below market in place leases for properties held and used in operations, were $299,616 and $218,006 as of December 31, 2011 and 2010, respectively, net of accumulated amortization of $78,030 and $68,914, respectively, as of those same respective dates. As of

December 31, 2010, the value of acquired in place leases and accumulated amortization, exclusive of the value of above and below market acquired in place leases, for properties held for sale was $4,353 and $4,012, respectively. Future amortization of intangible lease assets and liabilities to be recognized by us during the current terms of our leases as of December 31, 2011 are approximately $48,470 in 2012, $41,908 in 2013, $38,161 in 2014, $32,954 in 2015, $26,904 in 2016 and $85,341 thereafter.

        We recognize impairment losses on investments when indicators of impairment are present and the estimated undiscounted cash flow from our investments is less than the carrying amount of such investments. Impairment indicators may include declining tenant occupancy, lack of progress releasing vacant space, tenant bankruptcies, low long term prospects for improvement in property performance, weak or declining tenant profitability, cash flow or liquidity, our decision to dispose of an asset before the end of its estimated useful life and legislative, market or industry changes that could permanently reduce the value of a property. We review our properties for impairment quarterly, or whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. If indicators of impairment are present, we evaluate the carrying value of the related property by comparing it to the expected future undiscounted cash flows to be generated from that property. If the sum of these expected future cash flows is less than the carrying value, we reduce the net carrying value of the property to its estimated fair value. The determination of undiscounted cash flow includes consideration of many factors including income to be earned from the investment, holding costs (exclusive of interest), estimated selling prices, and prevailing economic and market conditions. During 2011, we recorded losses on asset impairment totaling $10,355 reflecting a $9,604 write down of 26 properties to estimated fair value based on broker valuations and an analysis of property level cash flows, and $751 of depreciation on one property with a net book value that was less than its estimated fair value.

        Certain of our real estate assets contain hazardous substances, including asbestos. We believe the asbestos at our properties is contained in accordance with current environmental regulations and we have no current plans to remove it, other than at one building in Monroeville, PA where we are renovating the property for new tenants. If these properties were demolished today, certain environmental regulations specify the manner in which the asbestos must be removed. Certain of our industrial lands in Hawaii may require expensive environmental remediation, especially if the use of those lands is changed; however, we do not have any present plans to change those land uses or to undertake this environmental clean up. We do not believe that there are other environmental conditions at any of our properties that have a material adverse effect on us. However, no assurances can be given that such conditions are not present in our properties or that other costs we incur to remediate contamination will not have a material adverse effect on our business or financial condition. As of December 31, 2011 and 2010, accrued environmental remediation costs totaling $14,625 and $16,465, respectively, were included in accounts payable and accrued expenses in our consolidated balance sheets.

        Cash and Cash Equivalents.    We carry cash and short term investments with original maturities of three months or less at the date of purchase at cost plus accrued interest.

        Restricted Cash.    Restricted cash consists of amounts escrowed for future real estate taxes, insurance, leasing costs, capital expenditures and debt service, as required by some of our mortgage debts, as well as security deposits paid to us by some of our tenants.

        Other Assets, Net.    Other assets consist principally of deferred financing fees, deferred leasing costs, capitalized lease incentives and prepaid property operating expenses. Deferred financing fees include issuance costs related to borrowings and are capitalized and amortized over the terms of the respective loans. At December 31, 2011 and 2010, deferred financing fees totaled $45,763 and $40,661, respectively, and accumulated amortization for deferred financing fees totaled $16,108 and $11,459, respectively, as of those same respective dates. Deferred leasing costs include brokerage, legal and other fees associated with the successful negotiation of leases and are amortized on a straight line basis over the terms of the respective leases. Deferred leasing costs for properties held and used in operations totaled $130,176 and $116,959 at December 31, 2011 and 2010, respectively, and accumulated amortization for deferred leasing costs for properties held and used in operations totaled $44,974 and $42,512, respectively, as of those same respective dates. Deferred leasing costs for properties held for sale totaled $0 and $2,703 at December 31, 2011 and 2010, respectively, and accumulated amortization for deferred leasing costs for properties held for sale totaled $0 and $1,018, respectively, as of those same respective dates. Capitalized lease incentives are amortized on a straight line basis to rental income over the terms of the respective leases. Capitalized lease incentives for properties held and used in operations totaled $16,636 and $14,716 at December 31, 2011 and 2010, respectively, and accumulated amortization for capitalized lease incentives for properties held and used in operations totaled $1,692 and $46, respectively, as of those same respective dates. Future amortization of deferred financing fees and leasing costs to be recognized by us during the current terms of our loans and leases as of December 31, 2011 are approximately $21,901 in 2012, $19,821 in 2013, $18,249 in 2014, $15,970 in 2015, $11,607 in 2016 and $27,309 thereafter. Future amortization of capitalized lease incentives to be recognized by us during the current terms of our leases as of December 31, 2011 are approximately $1,710 in 2012, $1,710 in 2013, $1,702 in 2014, $1,695 in 2015, $1,691 in 2016 and $6,436 thereafter.

        Accounting Policy for Derivative Instruments.    The Derivatives and Hedging Topic of The FASB Accounting Standards CodificationTM, or the Codification, requires companies to recognize all their derivative instruments as either assets or liabilities in the statement of financial position at fair value. The accounting for changes in the fair value of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and further, on the type of hedging relationship. For those derivative instruments that are designated and qualify as hedging instruments, we must designate the hedging instrument, based upon the exposure being hedged, as a fair value hedge, cash flow hedge or a hedge of a net investment in a foreign operation. In December 2009, we entered into interest rate swap agreements that qualify as cash flow hedges. As of December 31, 2011 and 2010, the fair value of our derivative instrument of $15,796 and $6,956, respectively, was included in accounts payable and accrued expenses and cumulative other comprehensive (loss) income in our consolidated balance sheets.

        We are exposed to certain risks relating to our ongoing business operations. The primary risk managed by using derivative instruments is interest rate risk. Interest rate swaps are entered into to manage interest rate risk associated with our floating rate borrowings. We designate certain interest rate swaps as cash flow hedges of floating rate borrowings.

        Revenue Recognition.    Rental income from operating leases, which includes rent concessions (including free rent and other lease incentives) and scheduled increases in rental rates during the lease

Note 2. Summary of Significant Accounting Policies (Continued)

term, is recognized on a straight line basis over the life of the lease agreements. We defer the recognition of contingent rental income, such as percentage rents, until the specific targets that trigger the contingent rental income are achieved.

        Allowance for Doubtful Accounts.    We maintain an allowance for doubtful accounts for estimated losses resulting from the inability or unwillingness of certain tenants to make payments required under their leases. The computation of the allowance is based on the tenants' payment histories and current credit profiles, as well as other considerations.

        Earnings Per Common Share.    Earnings per common share, or EPS, is computed using the weighted average number of common shares outstanding during the period. Diluted EPS reflects the potential dilution that could occur if our series D convertible preferred shares were converted into our common shares, where such conversion would result in a lower EPS amount. The effect of our series D convertible preferred shares on income from continuing operations and net income available for common shareholders is anti-dilutive for all periods presented.

        Reclassifications.    Reclassifications have been made to the prior years' financial statements and notes to conform to the current year's presentation.

        Income Taxes.    We are a REIT under the Internal Revenue Code of 1986, as amended and, are generally not subject to federal and state income taxes provided we distribute our taxable income to our shareholders and meet other requirements for qualifying as a real estate investment trust. However, we are subject to certain state, local and Australian taxes without regard to our REIT status.

        The Income Taxes Topic of the Codification prescribes how we should recognize, measure and present in our financial statements uncertain tax positions that have been taken or are expected to be taken in a tax return. Deferred tax assets are recognized to the extent that it is "more likely than not" that a particular tax position will be sustained upon examination or audit. To the extent the "more likely than not" standard has been satisfied, the benefit associated with a tax position is measured as the largest amount that has a greater than 50% likelihood of being realized upon settlement. We classify interest and penalties related to uncertain tax positions, if any, in our financial statements as a component of general and administrative expense.

        Use of Estimates.    Preparation of these financial statements in conformity with U.S. generally accepted accounting principles, or GAAP, requires us to make estimates and assumptions that may affect the amounts reported in these financial statements and related notes. The actual results could differ from these estimates.

        Foreign Operations.    The U.S. dollar is the functional currency for our consolidated subsidiaries operating in the United States. The functional currency for our consolidated subsidiaries in countries other than the United States is the principal currency in which the entity's assets, liabilities, income and expenses are denominated. The functional currency of our consolidated subsidiary that operates in Australia is the Australian dollar. We translate our Australian subsidiary's financial statements into U.S. dollars when we consolidate that subsidiary's financial statements on a quarterly basis. Generally, we translate assets and liabilities at the exchange rate in effect as of the balance sheet date. The resulting translation adjustments are included in cumulative other comprehensive income in our consolidated

Note 2. Summary of Significant Accounting Policies (Continued)

balance sheets. We translate income statement accounts using the average exchange rate for the period and income statement accounts that include significant non-recurring transactions at the rate in effect as of the date of the transaction. We are subject to foreign currency risk due to potential fluctuations in exchange rates between Australian and U.S. currencies. A significant change in the value of Australian currency compared to U.S. currency would have an effect on future reported results of operations and financial position. We do not currently borrow in Australian dollars or enter currency derivative contracts to mitigate foreign currency risk. As of December 31, 2011 and 2010, cumulative foreign currency translation adjustments were $11,009 and $11,641, respectively.

        New Accounting Pronouncements.    In December 2010, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update No. 2010-29, Business Combinations (ASC Topic 805)—Disclosure of Supplementary Pro Forma Information for Business Combinations. This update requires a public entity to disclose revenue and earnings of the combined entity as though the business combination that occurred during the current year had occurred as of the beginning of the prior year. It also requires a description of the nature and amount of material, nonrecurring adjustments directly attributable to the business combination included in the reported revenue and earnings. This update was effective for fiscal years beginning on or after December 15, 2010. The adoption of this update did not cause any material changes to the disclosures in our consolidated financial statements.

        In May 2011, the FASB issued Accounting Standards Update No. 2011-04, Amendments to Achieve Common Fair Value Measurements and Disclosure Requirements in U.S. GAAP and IFRS. This update clarifies the application of existing fair value measurement requirements. This update also requires reporting entities to disclose additional information regarding fair value measurements categorized within Level 3 of the fair value hierarchy. This update is effective for interim and annual reporting periods beginning after December 15, 2011. We do not expect the adoption of this update to cause any material changes to the disclosures in, or presentation of, our consolidated financial statements.

        In June 2011, the FASB issued Accounting Standards Update No. 2011-05, Presentation of Comprehensive Income. This update eliminates the current option to report other comprehensive income and its components in the statement of shareholders' equity. This update is intended to enhance comparability between entities that report under GAAP and to provide a more consistent method of presenting non-owner transactions that affect an entity's equity. This standard is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. We do not expect the adoption of this update to cause any material changes to the disclosures in, or the presentation of, our consolidated financial statements.

Note 3. Real Estate Properties

        During 2011, we acquired 23 properties with a combined 6,806,615 square feet for an aggregate purchase price of $1,144,852, including the assumption of $321,235 of mortgage debt and excluding closing costs, and we sold 20 properties with approximately 2,148,000 square feet for an aggregate sale price of $265,145, excluding closing costs. We also funded $104,653 of improvements to our owned properties during 2011. Since January 1, 2012, we have acquired an additional property with 1,006,574 square feet for a purchase price of $150,600, including the assumption of $147,872 of mortgage debt and excluding closing costs. We have also entered into agreements to acquire two properties with a combined 1,056,869 square feet for an aggregate purchase price of $148,000, including the assumption

        In October 2011, we entered an agreement to acquire an office property located in Hartford, CT with 884,669 square feet. The purchase price is $99,000, excluding closing costs. We expect to acquire this property during the first half of 2012; however, this acquisition is subject to customary closing conditions and we can provide no assurance that we will acquire this property in that time period or at all.

        In January 2012, we entered an agreement to acquire an office property located in Austin, TX with 172,200 square feet. The purchase price is $49,000, including the assumption of approximately $29,200 of mortgage debt and excluding closing costs. We expect to acquire this property during the first half of 2012; however, this acquisition is subject to customary closing conditions, including the assumption of existing mortgage debt, and we can provide no assurance that we will acquire this property in that time period or at all.

Property Sales:

        In November 2010, we entered into various agreements to sell 27 properties which are majority leased as medical office, clinic and biotech laboratory buildings to Senior Housing Properties Trust, or SNH, for an aggregate sale price of $470,000, excluding closing costs. In 2010, we sold 21 of these properties containing approximately 2,066,000 square feet for an aggregate sale price of $374,130, excluding closing costs, and recognized net gains totaling $133,272. In January 2011, we sold the remaining six properties containing approximately 737,000 square feet for an aggregate sale price of $95,870, excluding closing costs, and recognized gains totaling $35,000.

We previously granted SNH a right of first refusal to purchase certain of our properties if we sought to sell them. In connection with our September 2011 sale of 13 properties to SNH, we and SNH terminated the existing SNH right of first refusal as substantially all of the properties that were subject to that

right of first refusal had been purchased by SNH (See Note 9). Because we and SNH have three trustees in common and we are both managed by RMR, the terms of these transactions were negotiated and approved by special committees of our and SNH's boards of trustees composed solely of Independent Trustees who were not also Independent Trustees of both companies.

        In February 2011, we sold an industrial property located in Adairsville, GA with 101,400 square feet for $2,275, excluding closing costs, and recognized a loss of $94.

        As of December 31, 2011, none of our properties were classified as held for sale. As of December 31, 2010, we had 12 office properties with a combined 1,556,000 square feet and 22 industrial and other properties with a combined 2,171,000 square feet classified as held for sale in our consolidated balance sheet. As discussed above, we sold two of these industrial properties and five of these office properties during 2011. The remaining 20 industrial properties with a combined 1,834,000 square feet and seven office properties with a combined 1,054,000 square feet were reclassified to properties held and used in operations during the fourth quarter of 2011 when we determined, based on marketing efforts and economic conditions, that the sale of these properties was no longer probable.

        We classify all properties actively marketed, under contract, in active negotiations and otherwise probable for sale within one year as held for sale in our consolidated balance sheets. Results of operations for properties sold or held for sale are included in discontinued operations in our consolidated statements of income, except for properties sold during 2010 to GOV. Properties that we sold to GOV are not considered discontinued operations under GAAP because of our retained equity interest in this former subsidiary. Summarized balance sheet and income statement information for properties sold or held for sale, other than properties sold to GOV, is as follows:

        Our real estate properties are generally leased on gross lease, modified gross lease or triple net lease bases pursuant to non-cancelable, fixed term operating leases expiring between 2012 to 2051. The triple net leases generally require the lessee to pay all property operating costs. Our gross leases and modified gross leases require us to pay all or some property operating expenses and to provide all or some property management services.

        We committed $104,794 for expenditures related to 6,806,000 square feet of leases executed during 2011. Committed but unspent tenant related obligations based on executed leases as of December 31, 2011, were $71,305.

        The future minimum lease payments scheduled to be received by us during the current terms of our leases as of December 31, 2011 are as follows:

Note 4. Investment in Direct Financing Lease

        Our investment in a direct financing lease relates to the triple net lease with a term that exceeds 75% of the useful life of one office tower located within a mixed use property in Phoenix, AZ that we acquired in March 2011. We recognize direct financing lease income using the effective interest method to produce a level yield on funds not yet recovered. Estimated unguaranteed residual values at the date of lease inception represent our initial estimates of the fair value of the leased assets at the expiration of the lease, which do not exceed their original cost. Significant assumptions used in estimating residual values include estimated net cash flows over the remaining lease term and expected future real estate values. The following table summarizes the carrying amount of our net investment in the direct financing lease as of December 31, 2011. The carrying amount of our net investment is included in other assets in our consolidated balance sheet.

        Additionally, we have determined that no allowance for losses related to our direct financing lease was necessary at December 31, 2011.

        Our direct financing lease has an expiration date in 2045. Future minimum rentals receivable on this direct financing lease as of December 31, 2011 are $8,098 in 2012, $8,098 in 2013, $8,098 in 2014, $8,098 in 2015, $226 in 2016 and $6,564 thereafter.

Note 5. Equity Investments

        At December 31, 2011 and 2010, we had the following equity investments in GOV and AIC:

 
  Ownership Percentage   Equity Investments   Equity in Earnings (Loss)  
 
  December 31,   December 31,   Year Ended December 31,  
 
  2011   2010   2011   2010   2011   2010   2009  

GOV

    21.1 %   24.6 % $ 172,186   $ 166,388   $ 11,238   $ 8,465   $ 6,679  

AIC

    14.3 %   14.3 %   5,291     5,076     139     (1 )   (133 )
                                   

              $ 177,477   $ 171,464   $ 11,377   $ 8,464   $ 6,546  
                                   

        At December 31, 2011, we owned 9,950,000, or approximately 21.1%, of the common shares of beneficial interest of GOV, with a carrying value of $172,186 and a market value, based on quoted market prices, of $224,373 ($22.55 per share). GOV is a REIT which primarily owns properties that are majority leased to government tenants and was our wholly owned subsidiary until its initial public offering, or the GOV IPO, in June 2009 when it became a separate public entity. In July 2011, GOV issued 6,500,000 common shares in a public offering for $25.40 per common share, raising net proceeds of approximately $157,900. As a result of the per share sales price of this transaction being above our per share carrying value, our ownership percentage in GOV was reduced from 24.6% prior to this transaction to 21.1% after this transaction, and we recognized a gain of $11,177 (See Note 9).

        Since the GOV IPO, we have accounted for our investment in it using the equity method. Under the equity method, we record our percentage share of net earnings of GOV in our consolidated statements of income. Prior to the GOV IPO, the operating results and investments of GOV were included in our results of operations and financial position. The market value of our GOV common shares on the date of the GOV IPO exceeded our carrying value by $13,824. We are amortizing the difference between our carrying value of GOV and our share of the underlying equity of GOV over a 30 year period, which approximates the remaining useful lives of the properties that we initially contributed to GOV. If we determine there is an "other than temporary" decline in the fair value of this investment, we would record a charge to earnings.

        During the years ended December 31, 2011, 2010 and 2009, we received cash distributions from GOV totaling $16,617, $16,119 and $4,975, respectively.

        The following summarized financial data of GOV, as reported in GOV's Annual Report on Form 10-K for the year ended December 31, 2011, includes results of operations prior to June 8, 2009 (the date GOV became a separate public company), which are included in our consolidated results of operations when GOV was our wholly owned subsidiary. References in our financial statements to the Annual Report on Form 10-K for GOV are included as textual references only, and the information in GOV's Annual Report on Form 10-K is not incorporated by reference into our financial statements.

We may invest additional amounts in AIC in the future if the expansion of this insurance business requires additional capital, but we are not obligated to do so. At December 31, 2011, we owned

Note 5. Equity Investments (Continued)

approximately 14.3% of AIC with a current carrying value of $5,291. Although we own less than 20% of AIC, we use the equity method to account for this investment because we believe that we have significant influence over AIC because each of our Trustees is a director of AIC (See Note 2 and Note 9). Under the equity method, we record our percentage share of net earnings from AIC in our consolidated statements of income. If we determine there is an "other than temporary" decline in the fair value of this investment, we would record a charge to earnings. In evaluating the fair value of this investment, we have considered, among other things, the assets and liabilities held by AIC, AIC's overall financial condition, and the financial condition and prospects for AIC's insurance business.

        In June 2010, we and the other shareholders of AIC purchased property insurance providing $500,000 of coverage pursuant to an insurance program arranged by AIC and with respect to which AIC is a reinsurer of certain coverage amounts. This program was modified and extended in June 2011 for a one year term. Our annual premiums for this property insurance in 2011 and 2010 were $6,697 and $5,328, respectively. We are currently investigating the possibilities to expand our insurance relationships with AIC to include other types of insurance. By participating in this insurance business with RMR and the other companies to which RMR provides management services, we expect that we may benefit financially by possibly reducing our insurance expenses or by realizing our pro rata share of any profits of this insurance business.

Note 6. Real Estate Mortgage Receivable

        We provided mortgage financing totaling $8,288 at 4.75% per annum maturing in September 2020 in connection with an office property sold in September 2010. This real estate mortgage was prepaid in full in August 2011. As of December 31, 2010, this mortgage had a carrying value of $8,183 and was included in other assets in our consolidated balance sheet.

Note 7. Shareholders' Equity

Share Awards:

        We have common shares available for issuance under the terms of our award plan adopted in 2003, or the 2003 Plan. We awarded common shares to our officers and certain employees of RMR in 2011, 2010 and 2009. We also awarded each of our Trustees 2,000 common shares in 2011 with an aggregate market value of $266 ($53 per Trustee) on the date of the grant, 1,250 common shares in 2010 with an aggregate market value of $203 ($41 per Trustee) on the date of the grant, and 1,250 common shares in 2009 with an aggregate market value of $101 ($20 per Trustee) on the date of grant as part of their annual compensation. The common shares awarded to our Trustees vested immediately. The common shares awarded to our officers and certain employees of RMR vest in five equal annual installments beginning on the date of grant. We include the value of awarded shares in general and administrative expenses at the time the awards vest.

As of December 31, 2011, the estimated future compensation expense for the unvested shares was $1,724 based on the closing share price of our common shares on December 31, 2011 of $16.64. The weighted average period over which the compensation expense will be recorded is approximately 23 months. During the years ended December 31, 2011, 2010 and 2009, we recorded $1,139, $1,034 and $1,092, respectively, of compensation expense related to our 2003 Plan.

        At December 31, 2011, 1,335,960 common shares remain available for issuance under the 2003 Plan.

Distributions:

        In January 2012, we declared a distribution of $0.50 per common share, or $41,861, which we paid on February 21, 2012 to shareholders of record on January 20, 2012. Cash distributions per common share paid or accrued by us in 2011, 2010 and 2009, were $2.00, $1.48 and $2.40, respectively. The characterization of our distributions paid or accrued in 2011, 2010 and 2009 was 65.90%, 82.82% and 96.75% ordinary income, respectively, 23.54%, 17.18% and 0% return of capital, respectively, 7.34%, 0% and 3.25% Internal Revenue Code section 1250 gain, respectively, and 3.22%, 0% and 0% capital gain, respectively.

Our credit facility and term loan agreement contain a number of financial and other covenants, including a covenant which restricts our ability to make distributions under certain circumstances.

Preferred Shares:

        Our 6,000,000 series C cumulative redeemable preferred shares carry dividends of $1.78125, 71/8%, per annum, payable in equal quarterly payments. Each series C preferred share has a liquidation preference of $25.00 and is redeemable, at our option, for $25.00 each plus accrued and unpaid dividends at any time.

        Our 15,180,000 series D cumulative convertible preferred shares carry dividends of $1.625, 61/2%, per annum, payable in equal quarterly payments. Our series D preferred shares are convertible, at the holder's option, into our common shares at an initial conversion rate of 0.480775 common shares per series D preferred share, which is equivalent to an initial conversion price of $52.00 per common share, or 7,298,165 additional common shares at December 31, 2011. On or after November 20, 2011, if our common shares trade at or above the then applicable conversion price, we may, at our option, convert some or all of the series D preferred shares into common shares at the then applicable conversion rate. If a fundamental change occurs, which generally will be deemed to occur upon a change in control or a termination of trading of our common shares (or other equity securities into which our series D preferred shares are then convertible), holders of our series D preferred shares will have a special right to convert their series D preferred shares into a number of our common shares per $25.00 liquidation preference, plus accrued and unpaid distributions, divided by 98% of the market price, as defined, of our common shares, unless we exercise our right to repurchase these series D preferred shares for cash, at a purchase price equal to 100% of their liquidation preference, plus accrued and unpaid distributions.

        In June 2011, we issued 11,000,000 series E cumulative redeemable preferred shares in a public offering, raising net proceeds of $265,391. Each series E preferred share has a liquidation preference of $25.00 and requires dividends of $1.8125, 71/4% of the liquidation preference per annum, payable in equal quarterly payments. The series E preferred shares are redeemable at our option for $25.00 each plus accrued and unpaid distributions at any time on or after May 15, 2016 or if a change of control occurs which results in our common shares (or the common securities of an acquiring or surviving entity) not being listed or quoted on the New York Stock Exchange, or the NYSE, or certain other exchanges or quotation systems. Also, upon the occurrence of such a change of control, holders of series E preferred shares that we do not elect to redeem may at their option convert those series E preferred shares into our common shares (or certain alternative consideration) at a conversion rate generally based on their $25.00 liquidation preference and the market price of our common shares at the time of conversion, subject to a cap.

        We have adopted a Shareholders Rights Plan pursuant to which a right to purchase securities is distributable to shareholders in certain circumstances. Each right entitles the holder to purchase or to receive securities or other assets of ours upon the occurrence of certain events. The rights expire on October 17, 2014, and are redeemable at our option.

        A reconciliation of our effective tax rate and the U.S. Federal statutory income tax rate is as follows:

 
  Year Ended December 31,  
 
  2011   2010   2009  

Taxes at statutory U.S. federal income tax rate

    35.00 %   35.00 %   35.00 %

Dividends paid deduction

Effective tax rate

    1.22 %   0.40 %   0.40 %
               

        Deferred income tax assets and liabilities represent the tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes, and are determined using tax rates expected to be in effect when the deferred income tax assets and liabilities are anticipated to be paid or recovered. At December 31, 2011 and 2010, we had deferred tax assets of $1,992 and $1,270, respectively, of which $1,414 and $1,178, respectively, related to different carrying amounts for financial reporting and for Australian income tax purposes of our properties in Australia. At December 31, 2011 and 2010, we had deferred tax liabilities of $1,214 and $20, respectively. Because we are uncertain of our ability to realize the future benefit of certain Australian loss carry forwards, we have reduced our net deferred income tax assets by a valuation allowance of $165 and $160 as of December 31, 2011 and 2010, respectively.

Note 9. Related Person Transactions

        We have adopted written Governance Guidelines that address, among other things, the consideration and approval of any related person transactions. Under these Governance Guidelines, we may not enter into any transaction in which any Trustee or executive officer, any member of the immediate family of any Trustee or executive officer or any other related person, has or will have a direct or indirect material interest unless that transaction has been disclosed or made known to our Board of Trustees and our Board of Trustees reviews, authorizes and approves or ratifies the transaction by the affirmative vote of a majority of the disinterested Trustees, even if the disinterested

Note 9. Related Person Transactions (Continued)

Trustees constitute less than a quorum. If there are no disinterested Trustees, the transaction shall be reviewed, authorized and approved or ratified by both (1) the affirmative vote of a majority of our entire Board of Trustees and (2) the affirmative vote of a majority of our Independent Trustees. The Governance Guidelines further provide that, in determining whether to approve or ratify a transaction, our Board of Trustees, or disinterested Trustees or Independent Trustees, as the case may be, shall act in accordance with any applicable provisions of our declaration of trust, consider all of the relevant facts and circumstances and approve only those transactions that are fair and reasonable to us. All related person transactions described below were reviewed and approved or ratified by a majority of the disinterested Trustees or otherwise in accordance with our policies described above. In the case of transactions with us by RMR employees (other than our Trustees and executive officers) subject to our Code of Business Conduct and Ethics, the employee must seek approval from an executive officer who has no interest in the matter for which approval is being requested.

        We have no employees. Personnel and various services we require to operate our business are provided to us by RMR. We have two agreements with RMR to provide management and administrative services to us: (1) a business management agreement and (2) a property management agreement. One of our Managing Trustees, Mr. Barry Portnoy, is Chairman, majority owner and an employee of RMR. Our other Managing Trustee, Mr. Adam Portnoy, who is also our President, is the son of Mr. Barry Portnoy, an owner, President and Chief Executive Officer, and a Director of RMR. Each of our other executive officers is also an officer of RMR. Additionally, Mr. Barry Portnoy's son-in-law, who is Mr. Adam Portnoy's brother-in-law, is an officer of RMR. RMR has approximately 740 employees and provides management services to other companies in addition to us.

        Our Board of Trustees has given our Compensation Committee, which is comprised exclusively of our Independent Trustees, authority to act on our behalf with respect to our management agreements with RMR. The charter of our Compensation Committee requires the Committee annually to review the terms of these agreements, evaluate RMR's performance under the agreements and renew, amend, terminate or allow to expire the management agreements.

        On November 1, 2011, we and RMR entered into an amended and restated business management agreement, or the business management agreement. The business management agreement provides for compensation to RMR at an annual rate equal to 0.7% of the average historical cost of our real estate investments, as described in the business management agreement, located in the United States, Puerto Rico or Canada, for the first $250,000 of such investments, and 0.5% thereafter, and 1.0% of the average historical cost of our real estate investments located outside the United States, Puerto Rico and Canada. In addition, RMR receives an incentive fee equal to 15% of the product of (i) the weighted average of our common shares outstanding on a fully diluted basis during such fiscal year and (ii) the excess if any of FFO Per Share, as defined in the business management agreement, for such fiscal year over the FFO Per Share for the preceding fiscal year. The incentive fee is paid in our common shares and in any year shall not exceed $0.04 multiplied by the weighted average number of our common shares outstanding on a fully diluted basis during such fiscal year. Our investment in GOV, which is described below, is not counted for purposes of determining the business management fees payable by us to RMR.

        In determining the fees payable by us to RMR under the business management agreement, the average invested capital of any assets we have acquired or may in the future acquire from another REIT to which RMR provides business management or property management services, or an RMR

Managed REIT, will be equal to the applicable selling RMR Managed REIT's historical costs for those properties, determined in the manner specified in the business management agreement, rather than our acquisition costs for those properties. The business management agreement also provides that, with certain exceptions, if we determine to offer for sale or other disposition any real property that, at such time, is of a type within the investment focus of another RMR Managed REIT, we will first offer that property for purchase or disposition to that RMR Managed REIT and negotiate in good faith for such purchase or disposition.

        The property management agreement provides for management fees equal to 3.0% of gross collected rents and construction supervision fees equal to 5.0% of construction costs. However, with respect to our investments in Australia, RMR has agreed to waive half of the fees payable by us under the property management agreement and half of the business management fees related to real estate investments located outside of the United States, Puerto Rico and Canada, so long as our business and property management agreement with MacarthurCook Fund Management Limited with respect to those investments is in effect and we or any of our subsidiaries are paying fees under that agreement.

        The aggregate business management and property management fees earned by RMR for 2011, 2010 and 2009 were $69,518, $62,232 and $62,563 (which amount includes approximately $2,400 allocated to GOV before GOV became a separate public company), respectively. In addition, MacarthurCook Fund Management Limited earned $1,856 in 2011 and $185 in 2010 with respect to our Australian properties, which amounts are equal to the fees waived by RMR and excluded from the amounts earned by RMR during those years. Business management fees are included in general and administrative expenses and property management fees are included in operating expenses or have been capitalized as appropriate, in our consolidated financial statements. No incentive fees were earned by RMR in 2011, 2010 and 2009 because the FFO Per Share in these years did not exceed the immediately preceding fiscal year's FFO Per Share.

        RMR also provides internal audit services to us in return for our pro rata share of the total internal audit costs incurred by RMR for us and other publicly owned companies managed by RMR and its affiliates, which amounts are subject to determination by our Compensation Committee. Our Audit Committee appoints our Director of Internal Audit. Our pro rata share of RMR's costs of providing this internal audit function was approximately $240, $213 and $220 for 2011, 2010 and 2009, respectively, which are included in general and administrative expenses in our consolidated financial statements. These allocated costs are in addition to the business and property management fees we paid to RMR. We are generally responsible for all of our operating expenses, including certain expenses incurred by RMR on our behalf. We are not responsible for payment of RMR's employment, office or administration expenses incurred to provide management services to us, except for the employment and related expenses of RMR employees who provide on-site property management services and our pro rata share of the staff employed by RMR who perform our internal audit function.

        Both the business management agreement and the property management agreement automatically renew for successive one year terms unless we or RMR give notice of non-renewal before the end of an applicable term. We or RMR may terminate either agreement upon 60 days prior written notice. RMR may also terminate the property management agreement upon five business days notice if we undergo a change of control, as defined in the property management agreement. The current terms for these agreements expire on December 31, 2012, and will be subject to automatic renewal unless earlier terminated.

        Under our business management agreement with RMR, we acknowledge that RMR manages other businesses, which include Hospitality Properties Trust, or HPT, SNH, GOV, Five Star Quality Care, Inc., or Five Star, TravelCenters of America LLC, or TA, and Sonesta International Hotels Corporation and will not be required to present us with opportunities to invest in properties that are primarily of a type that are within the investment focus of another business now or in the future managed by RMR. Each of the business management agreement and the property management agreement also includes arbitration provisions for the resolution of certain disputes, claims and controversies.

        RMR also leases from us approximately 24,000 square feet of office space for eight regional offices. We earned approximately $566, $498 and $531 in rental income from RMR in 2011, 2010 and 2009, respectively, which we believe is commercially reasonable rent for this office space.

        Pursuant to our business management agreement, RMR may from time to time negotiate on our behalf with certain third party vendors and suppliers for the procurement of services to us. As part of this arrangement, we may enter agreements with RMR and other companies to which RMR provides management services for the purpose of obtaining more favorable terms with such vendors and suppliers.

        As part of our annual restricted share grants under the 2003 Plan, we typically grant restricted shares to certain employees of RMR, some of whom are our executive officers, in their capacities as RMR employees or executive officers of us. In 2011, 2010 and 2009, we granted a total of 73,050 restricted shares with an aggregate value of $1,458, 42,375 restricted shares with an aggregate value of $1,157 and 38,000 restricted shares with an aggregate value of $1,143, respectively, to such persons in such capacities, based upon the closing price of our common shares on the NYSE on the date of grant. One fifth of those restricted shares vested on the grant date and one fifth vests on each of the next four anniversaries of the grant date. These share grants to RMR employees are in addition to the fees we pay to RMR.

        SNH was formerly our 100% owned subsidiary. It was spun off to our shareholders in 1999. At the time of SNH's spin off, we and SNH entered into a transaction agreement pursuant to which, among other things, we and SNH agreed that so long as we own 10% or more of SNH's common shares, we and SNH engage the same manager or we and SNH have any common managing trustees: (1) we will not make any investment in senior apartments, congregate communities, assisted living properties, nursing homes or other healthcare properties, but excluding medical office properties, medical clinics and clinical laboratory buildings, without the prior approval of a majority of SNH's independent trustees, and (2) SNH will not make any investment in office buildings, warehouses or malls, including medical office properties and clinical laboratory buildings without the prior approval of a majority of our Independent Trustees.

        In May 2008, concurrently with our agreements to sell 47 medical office, clinic and biotech laboratory buildings to SNH for $562,000, we and SNH entered into an amendment to the transaction agreement to permit SNH, rather than us, to invest in medical office, clinic and biomedical, pharmaceutical and laboratory buildings. At the same time, we granted SNH a right of first refusal to purchase up to 45 additional identified properties that we owned and that were leased to tenants in medical related businesses in the event that we determined to sell such properties, including an indirect sale as a result of a change of control of us or our subsidiaries which owned those properties. Between November 2010 and January 2011, we sold to SNH 27 properties (approximately 2,803,000 square feet), which were majority leased as medical office, clinic and biotech laboratory buildings, for an aggregate

sale price of $470,000, excluding closing costs. We recognized net gains totaling approximately $168,272 from these sales. On September 30, 2011, we sold to SNH 13 additional properties (approximately 1,310,000 square feet), which were located in eight states and majority leased as medical office buildings and to tenants in medical related businesses, for an aggregate sale price of $167,000, excluding closing costs, and we recognized net gains totaling $7,846 from these sales. Certain of the properties included in these sales were subject to SNH's right of first refusal referred to above. In connection with our September 2011 sale of 13 properties to SNH, we and SNH terminated the existing SNH right of first refusal, as substantially all of the properties that were subject to that right of first refusal had been purchased by SNH. Our sale agreements with SNH include arbitration provisions for the resolution of certain disputes, claims and controversies.

        As of February 22, 2012, SNH owned 250,000 of our common shares. Both we and SNH are managed by RMR; Mr. Barry Portnoy and Mr. Adam Portnoy are Managing Trustees of both us and SNH; and Frederick N. Zeytoonjian is an Independent Trustee of both us and SNH. Also, all of our and SNH's officers are employees of RMR. Accordingly, the sale and amendment agreements between us and SNH described above were negotiated and approved by special committees of each company's board of trustees comprised solely of Independent Trustees who were not also Independent Trustees of the other company.

        GOV was formerly our 100% owned subsidiary. In June 2009, GOV completed an initial public offering pursuant to which GOV ceased to be a majority owned subsidiary of ours. In connection with this offering, we and GOV entered a transaction agreement, which governs our separation from and relationship with GOV. Pursuant to this transaction agreement, among other things, we and GOV agreed that, so long as we own in excess of 10% of GOV's outstanding common shares, we and GOV engage the same manager or we and GOV have any common managing trustees: (1) we will not acquire ownership of properties that are majority leased to government tenants, unless a majority of GOV's independent trustees who are not also our Trustees have determined not to make the acquisition; (2) GOV will not acquire ownership of office or industrial properties that are not majority leased to government tenants, unless a majority of our Independent Trustees who are not also GOV's trustees have determined not to make the acquisition; and (3) GOV will have a right of first refusal to purchase any property owned by us that we determine to divest if the property is then majority leased to government tenants, which right of first refusal will also apply in the event of an indirect sale of any such properties resulting from a change of control of us. The provisions described in (1) and (2) do not prevent GOV from continuing to own and lease its current properties or properties otherwise acquired by GOV that cease to be majority leased to government tenants following the termination of government tenancies; and, similarly, the provisions described in (1) and (2) also do not prohibit us from leasing our current or future properties to government tenants. We and GOV also agreed that certain disputes, claims and controversies arising under the transaction agreement may be referred to binding arbitration proceedings.

        In June 2010, we entered into a series of agreements to sell to GOV 15 properties (approximately 1,900,000 rentable square feet) which are majority leased to government tenants. We completed the sale of all 15 of these properties in 2010 for an aggregate sale price of $231,000, excluding closing costs, and recognized gains totaling $34,336, exclusive of deferred gains of $14,588 attributable to our ownership interest in GOV. These 15 properties were subject to the right of first refusal we granted to

GOV in the transaction agreement described above. Our sale agreements with GOV include arbitration provisions for the resolution of certain disputes, claims and controversies.

        We are GOV's largest shareholder and as of February 22, 2012, we owned 9,950,000 common shares of GOV, which represented approximately 21.1% of GOV's outstanding common shares. Both we and GOV are managed by RMR, Mr. Barry Portnoy and Mr. Adam Portnoy are Managing Trustees of both us and GOV and Mr. Adam Portnoy is our President and was the President of GOV from its formation in 2009 until January 2011 when he became our President. Also, all of our officers and GOV's officers are officers of RMR. Accordingly, the sale agreements between us and GOV described above and the transactions contemplated by those agreements, which we entered into with GOV after GOV became a separate public company, were negotiated and approved by special committees of each company's board of trustees, comprised solely of Independent Trustees who are not also Independent Trustees of the other party to these agreements.

        Our Independent Trustees also serve as directors or trustees of other public companies to which RMR provides management services. Mr. Barry Portnoy serves as a managing director or managing trustee of those companies, including SNH, GOV, HPT, Five Star and TA, and Mr. Adam Portnoy serves as a managing trustee of some of those companies, including SNH, GOV and HPT. We understand that the other companies to which RMR provides management services also have certain other relationships with each other, including business and property management agreements and lease arrangements. In addition, officers of RMR serve as officers of those companies. We understand that further information regarding those relationships is provided in the applicable periodic reports and proxy statements filed by those other companies with the Securities and Exchange Commission, or the SEC.

        On December 22, 2011, our wholly owned subsidiary, Select Income REIT, or SIR, filed a registration statement with the SEC for an IPO of common shares as a REIT that is focused on owning and investing in net leased, single tenant properties. If the SIR registration statement becomes effective and the IPO is completed, we expect to continue to own a majority of SIR's common shares after the completion of the offering and because of our retained majority interest in SIR, we expect SIR will remain one of our consolidated subsidiaries. On February 16, 2012, we transferred 251 properties (approximately 21,400,000 rentable square feet) to SIR, including substantially all of our commercial and industrial properties located in Oahu, HI and 23 suburban office and industrial properties located throughout the mainland U.S. In exchange for our contribution of 251 properties to SIR, we received 22,000,000 SIR common shares and a $400,000 demand promissory note, or the Demand Note. We expect that SIR would use net proceeds of its proposed IPO to repay in part amounts outstanding under the Demand Note. Upon completion of the IPO, SIR expects to enter into a $500,000 bank facility with a group of commercial banks. Upon completion of the IPO, SIR intends to borrow under the bank facility to repay the balance of the Demand Note and reimburse us for the costs we incurred in organizing SIR, establishing its bank facility and preparing for its IPO. There can be no assurance that SIR will be successful in completing its share offering and establishing the bank facility or that it will have the funds to repay the Demand Note or to reimburse us for the costs we incurred in organizing SIR.

        In order to govern the separation of SIR from us, upon completion of the IPO, we intend to enter into a transaction agreement with SIR. We expect that the transaction agreement will provide, among other things, that (1) the current assets and liabilities of the properties to be transferred to SIR will, as

F-29

of the time of the closing of the IPO of SIR's common shares, be settled between us and SIR so that we will retain all pre-closing current assets and liabilities and SIR will assume all post-closing current assets and liabilities and (2) SIR will indemnify us with respect to any liability relating to any property transferred to it by us, including any liability which relates to periods prior to SIR's formation.

        Our two Managing Trustees, Mr. Barry Portnoy and Mr. Adam Portnoy, are also trustees of SIR, and Mr. John Popeo, our Treasurer and Chief Financial Officer, also serves as the Treasurer and Chief Financial Officer of SIR. In addition, if the IPO is completed, it is currently expected that Mr. William Lamkin, one of our Independent Trustees, will serve as an independent trustee of SIR.

        If the SIR IPO is completed, we also expect that RMR will provide business and property management services to SIR. We expect that SIR will enter into management agreements with RMR that are on terms that are substantially similar to our management agreements with RMR. Accordingly, our management fees to RMR may be reduced by the amount of the management fees that would have otherwise been payable by us with respect to properties contributed by us to SIR. The SIR IPO will not occur unless, among other things, the SEC has declared the registration statement to be effective and underwriters have agreed to purchase and distribute the shares proposed to be offered by SIR. In addition, we may determine in our discretion, due to market conditions or otherwise, not to proceed with the SIR IPO. Accordingly, there can be no assurance that the IPO will occur.

        We, RMR, SNH, GOV, HPT, Five Star and TA each currently own approximately 14.3% of AIC, an Indiana insurance company. All of our Trustees, all of the trustees and directors of the other publicly held AIC shareholders and nearly all of the directors of RMR currently serve on the board of directors of AIC. RMR provides management and administrative services to AIC pursuant to a management and administrative services agreement with AIC. Our Governance Guidelines provide that any material transaction between us and AIC shall be reviewed, authorized and approved or ratified by both the affirmative vote of a majority of our entire Board of Trustees and the affirmative vote of a majority of our Independent Trustees. The shareholders agreement that we, the other shareholders of AIC and AIC are parties to includes arbitration provisions for the resolution of certain disputes, claims and controversies.

        As of February 22, 2012, we have invested $5,209 in AIC since its formation in November 2008. We may invest additional amounts in AIC in the future if the expansion of this insurance business requires additional capital, but we are not obligated to do so. For 2011, we recognized income of $139 related to our investment in AIC. For 2010 and 2009, we recognized losses of $1 and $133, respectively, related to our investment in AIC. In June 2010, we and the other shareholders of AIC purchased property insurance providing $500,000 of coverage pursuant to an insurance program arranged by AIC and with respect to which AIC is a reinsurer of certain coverage amounts. This program was modified and extended in June 2011 for a one year term. Our annual premiums for this property insurance in 2011 and 2010 were $6,697 and $5,328, respectively. We are currently investigating the possibilities to expand our insurance relationships with AIC to include other types of insurance. By participating in this insurance business with RMR and the other companies to which RMR provides management services, we expect that we may benefit financially by possibly reducing our insurance expenses or by realizing our pro rata share of any profits of this insurance business.

Note 10. Indebtedness (Continued)

        In March 2011, we repaid at maturity all $168,219 of our floating rate senior notes using borrowings under our revolving credit facility. In June 2011, we repaid at maturity $29,188 of 7.435% mortgage debt and in July 2011, we prepaid at par plus a premium $23,168 of 8.05% mortgage debt due in 2012 using cash on hand and proceeds from our common share offering completed in July 2011. In connection with the mortgage prepaid in July 2011, we recorded a net gain on early extinguishment of debt of $310 from the write off of unamortized premiums and deferred financing fees.

        In June 2011, we assumed mortgages on four properties totaling $14,960, which were recorded at a combined fair value of $15,894, in connection with our acquisition of those properties. These debts bear interest at a weighted average rate of 6.35%, require monthly principal and interest payments and mature in 2012 and 2015. In June 2011, we assumed $41,275 of mortgage debt, which was recorded at its fair value of $44,560, in connection with another acquisition. This mortgage debt bears interest at 5.67%, requires monthly interest payments and matures in 2017. In August 2011, we assumed $265,000 of mortgage debt, which was recorded at its fair value of $278,671, in connection with another acquisition. This mortgage debt bears interest at 5.68%, requires monthly interest payments and matures in 2017.

        During October 2011, our $750,000 unsecured revolving credit facility that we use for acquisitions, working capital and general business purposes was amended. Prior to this amendment, our credit facility matured on August 8, 2013 and included a conditional option for us to extend the facility for one year to August 8, 2014. The October 2011 amendment extends the maturity date from August 8, 2013 to October 19, 2015, with an option to extend the facility an additional year to October 19, 2016, subject to satisfaction of certain conditions, and includes a feature under which maximum borrowings may be increased to up to $1,500,000 in certain circumstances. The amendment also reduces the interest rate paid on our borrowings under the revolving credit facility from LIBOR plus 200 basis points to LIBOR plus 125 basis points, subject to adjustments based on our credit ratings. In connection with this amendment, we recorded a loss on early extinguishment of debt of $345 from the write off of unamortized deferred financing fees relating to lenders that did not commit to the amended terms. The interest rate on our revolving credit facility averaged 2.2% and 1.8% per annum for the years ended December 31, 2011 and 2010, respectively. As of December 31, 2011, we had $100,000 outstanding and $650,000 available under our revolving credit facility.

        In October 2011, we amended our existing term loan and increased its size from $400,000 to $557,000. Prior to this amendment, our term loan had a maturity date of December 15, 2015 and an interest rate set at LIBOR plus 200 basis points, subject to adjustments based on changes to our credit ratings. The amended term loan eliminates the prepayment premium, extends the maturity date to December 15, 2016, and reduces interest we pay on borrowings to LIBOR plus 150 basis points, subject to adjustments based on changes to our credit ratings. In addition, the amended term loan includes a feature under which maximum borrowings may be increased to up to $1,000,000 in certain circumstances. Three lenders representing $57,000 of aggregate borrowings did not commit to the amended term loan. Accordingly, these three lenders will be subject to the terms of the old term loan and we have agreed to repay these lenders in December 2012 when there will be no prepayment penalty.

        Our public debt indentures, our credit facility agreement and our term loan agreement contain a number of financial and other covenants, including a credit facility and term loan covenant that

restricts our ability to make distributions under certain circumstances. At December 31, 2011, we believe we were in compliance with all of our covenants under our public debt indentures, our revolving credit facility and term loan agreements.

        At December 31, 2011, 23 properties costing $914,400 with an aggregate net book value of $799,787 were secured by mortgage notes totaling $632,301 (net of premiums and discounts) maturing from 2012 through 2027.

        The required principal payments due during the next five years and thereafter under all our outstanding debt at December 31, 2011, are as follows:

        In January 2012, we prepaid at par all $150,680 of our 6.95% senior notes due 2012, using cash on hand and borrowings under our revolving credit facility. In February 2012, we repaid at maturity $5,404 of 7.31% mortgage debt using cash on hand.

Note 11. Fair Value of Assets and Liabilities

Although we have determined that the majority of the inputs used to value our derivatives fall within level 2 of the fair value hierarchy, the credit valuation adjustments associated with our derivatives utilize level 3 inputs, such as estimates of current credit spreads, to evaluate the likelihood of default by us and the counterparties.

Note 11. Fair Value of Assets and Liabilities (Continued)

(2)
Long-lived assets held and used consist of six office properties and 20 industrial properties that were written down from their carrying value of $42,322 to their estimated fair value of $32,718, resulting in an impairment charge of $9,604 in our Other Markets segment for the year ended December 31, 2011. The fair value for these properties was estimated as of November 30, 2011 and is not indicative of estimated market value as of December 31, 2011. We used broker information and comparable sales transactions for 21 properties and the sum of their expected future discounted cash flows for five properties (level 3 inputs) less estimated closing costs to determine the fair value of these properties. We estimate aggregate future cash flows expected to be generated by each property based on a number of factors such as market rents, operating expenses, discount rates and capitalization rates. These factors are generally based on our experience in local real estate markets and the effects of current market conditions.

        We are exposed to certain risks relating to our ongoing business operations, including the effect of changes in foreign currency exchange rates and interest rates. The only risk currently managed by using our derivative instruments is a part of our interest rate risk. Although we have not done so as of December 31, 2011 and have no present intention to do so, we may manage our Australian currency exchange exposure by borrowing in Australian dollars or using derivative instruments in the future, depending on the relative significance of our business activities in Australia at that time. We have interest rate swap agreements to manage our interest rate risk exposure on $175,000 of mortgage notes due 2019, which require interest at a spread over LIBOR. The interest rate swap agreements utilized by us qualify as cash flow hedges and effectively modify our exposure to interest rate risk by converting our floating interest rate debt to a fixed interest rate basis for this loan through December 1, 2016, thus reducing the impact of interest rate changes on future interest expense. These agreements involve the receipt of floating interest rate amounts in exchange for fixed rate interest payments over the life of the agreements without an exchange of the underlying principal amount. The fair value of our derivative instruments decreased by $8,840 and $9,501 during the years ended December 31, 2011 and 2010, respectively, based primarily on changes in market interest rates. As of December 31, 2011 and 2010, the fair value of these derivative instruments included in accounts payable and accrued expenses and cumulative other comprehensive (loss) income in our consolidated balance sheets totaled ($15,796) and ($6,956), respectively. We may enter additional interest rate swaps or hedge agreements to manage some of our additional interest rate risk associated with our floating rate borrowings.

        In addition to the assets and liabilities described in the above table, our financial instruments include our cash and cash equivalents, rents receivable, equity investments, investment in direct financing lease receivable, restricted cash, revolving credit facility, senior notes and mortgage notes payable, accounts payable and accrued expenses, rent collected in advance, security deposits and

amounts due to related persons. At December 31, 2011 and 2010, the fair values of these additional financial instruments were not materially different from their carrying values, except as follows:

Senior notes and mortgage notes payable

  $ 2,745,331   $ 2,924,141   $ 2,462,847   $ 2,599,075  

        At December 31, 2011 and 2010, the fair values of our equity investment in GOV are based on quoted market prices of $22.55 and $26.79, respectively. The fair values of our senior notes and mortgage notes payable are based on estimates using discounted cash flow analyses and currently prevailing interest rates adjusted by credit risk spreads.

        Other financial instruments that potentially subject us to concentrations of credit risk consist principally of rents receivable; however, no single tenant of ours is responsible for more than 3% of our total rents.

        We maintain derivative financial instruments, including interest rate swaps, with major financial institutions and monitor the amount of credit exposure to any one counterparty.

Note 12. Segment Information

        As of December 31, 2011, we owned 45 Central Business District, or CBD, office properties, 272 suburban office properties and 199 industrial & other properties. We account for all of these properties in geographic operating segments for financial reporting purposes based on our method of internal reporting. We account for our properties by property type (i.e. CBD office, suburban office and industrial & other) and by geographic regions. We define these individual geographic segments as those which currently, or during either of the last two quarters, represent or generate 5% or more of our total square feet, annualized revenues or property net operating income, or NOI, which we define as rental income less operating expenses. Our geographic segments include Metro Philadelphia, PA, Oahu, HI, Metro Chicago, IL, Metro Denver, CO, Australia, Metro Washington, DC and Other Markets, which includes properties located elsewhere throughout the United States. Prior periods have been restated to reflect 12 office properties and one industrial property reclassified to discontinued operations from continuing operations during the third quarter of 2011 and seven office properties and 20 industrial properties reclassified to continuing operations from discontinued operations during the fourth quarter of 2011.

        The following items are accounted for on a corporate level and are not allocated among our segments: depreciation and amortization expense, general and administrative expense, loss on asset impairment, acquisition related costs, interest and other income and expense, (loss) gain on early extinguishment of debt, equity in earnings of investees, gain on issuance of shares by an equity investee, gain on asset acquisition and gain on sale of properties. The accounting policies of our segments are the same as the accounting policies described in our summary of significant accounting policies.

        The following table reconciles our calculation of NOI to net income, the most directly comparable financial measure under GAAP reported in our consolidated financial statements. We define NOI as rental income from real estate less our property operating expenses. We consider NOI to be appropriate supplemental information to net income because it helps both investors and management to understand the operations of our properties. We use NOI internally to evaluate individual, regional and company wide property level performance and believe NOI provides useful information to investors regarding our results of operations because it reflects only those income and expense items that are incurred at the property level and may facilitate comparisons of our operating performance between

periods. The calculation of NOI excludes certain components of net income in order to provide results that are more closely related to our properties' results of operations. This measure does not represent cash generated by operating activities in accordance with GAAP and should not be considered as an alternative to net income, net income available for common shareholders or cash flow from operating activities determined in accordance with GAAP, or as an indicator of our financial performance or liquidity, nor is this measure necessarily indicative of sufficient cash flow to fund all of our needs. We believe that this data may facilitate an understanding of our consolidated historical operating results. This measure should be considered in conjunction with net income, net income available for common shareholders and cash flow from operating activities as presented in our Consolidated Statements of Income and Consolidated Statements of Cash Flows. Other REITs and real estate companies may calculate NOI differently than we do. A reconciliation of NOI to net income for the years ended December 31, 2011, 2010 and 2009, is as follows:
