Wood grain and polished concrete. Layers of visual interest stacked between open floorplates and tall ceilings. Buildings rich with architectural integrity, nestled in neighborhoods known for buzzing eateries and vibrant cultural scenes. the These and many other elements color environments in which today’s leading companies want to work and the types of properties for which Columbia Property Trust is known today. We have spent the past five years curating a portfolio of distinctive properties in the nation’s leading gateway markets. Positioned in the path of changing workplace tastes, these properties offer the greatest opportunity to deliver sustainable and growing returns to you, our stockholders. Today, we have one of the best-positioned portfolios across the entire office sector, with 80% of our assets in New York, San Francisco and Washington, D.C. As we assembled our portfolio, we sought properties that not only had the right address, appropriate size, and “great bones” architecturally and structurally, but that also had embedded untapped value. We acquired vacancy, below-market in-place rents, and under-managed properties, from which we’ve driven higher rents, occupancy and value. The benefits of this approach came fully into focus in 2018. By successfully executing on the value creation opportunities throughout our portfolio – leasing up vacancy, rolling up under-market leases, repositioning tenant rosters, completing building and amenity improvements, and enhancing our service delivery to tenants – we were able to deliver dramatic growth in rents and net operating income (NOI) in 2018.1 The growth in NOI on our same- Columbia Property Trust | Annual Report 2018 2 “Today, we have one of the best-positioned portfolios across the entire office sector, with 80% of our assets in New York, San Francisco and Washington, D.C. “ store portfolio – those properties we have operated for at least two full years – was among the strongest in the office sector, at 13.9%. Furthermore, we achieved 37% growth in our Normalized Funds from Operations (NFFO), exceeding the high end of our guidance range.1 Our Team Drives Our Success The strong results we delivered in 2018, as well as the company’s significant capacity for future growth, are due to the success of another leg of our strategy – we have intentionally developed dedicated and highly capable leasing and operations teams in each of our key markets. to local leadership In addition in both San Francisco and Washington, D.C., we augmented our crucial New York team’s capabilities last year when we welcomed a veteran of the New York real estate market. David Cheikin has built a respected reputation for his leadership in several significant repositioning projects in the northeast, and he is now using that experience to advance Columbia’s real estate operations in New York, Washington D.C. and Boston as Senior Vice President of Strategic Real Estate Initiatives. Combined with my own 2017 move to Manhattan, we have now centered our strategic leadership in New York, our largest market. Across the board, our local teams in New York, San Francisco and D.C. continue to drive our success in leasing and operations. Even though we have achieved high occupancy across our portfolio, and less than 10% of our leases expire this year or next, our team continues to deliver gains in rents, occupancy and lease term that will drive cash flow growth well into the future. In 2018, we leased a total of 1.1 million square feet of space while driving rental rates 19% higher, on average.2 By the end of 2018, our portfolio was 97% leased, with substantially improved cash flows, and a tenant roster including many of the most dynamic and successful companies in the world. Twitter, DocuSign, Affirm, Oracle, Wells Fargo, and Amazon Web Services are just a few of the leading corporations that have chosen a Columbia building for their workspace because of the type of environments we’ve created for their employees, in the neighborhoods in which they want to operate.

Creating value requires the ability to see unexpected solutions. In the last year, we’ve completed strategic upgrades to the common areas and services at 315 Park Avenue South in New York, and 221 Main Street and 650 California in San Francisco, to help them stand out from the crowd. In combination with targeted marketing, this has enabled us to lease more than 538,000 square feet over the past two years across these three properties alone, and achieve average leasing spreads of 33%, 80%, and 121%, respectively. We had planned to reposition 149 Madison in New York for multiple tenants but encountered intense single user interest. A 16-year lease with WeWork removed our re-development risk while still achieving our targeted rents and returns. In nearby Chelsea, we achieved a five- year extension with Twitter, at stepped-up terms, while also adding a value-enhancing amenity to the property. Columbia Property Trust | Annual Report 2018 4 We’re identifying and executing opportunities to achieve higher rents, occupancy and asset value across the portfolio. Positioning for Value Sometimes elbow grease is the answer. We’ve taken strategic steps to position our three remaining noncore assets to attract wide buyer interest and optimal pricing. In Atlanta, we fully leased our two Glenlake buildings before marketing them for sale, and we acquired the retail buildings adjoining Lindbergh Center in order to market that property as a full campus opportunity. In Pittsburgh, we mitigated infrastructure challenges at Westinghouse’s campus, resulting in a successful renewal for the full property. Recognizing Created Value Leasing is only part of our value-creation story though. Our Transactions team, which has led more than $6.4 billion in total acquisitions and dispositions for the company so far, closed yet another significant transaction in 2018 with the sale of 222 East 41st Street in New York. This 25-story tower had been leased to Jones Day since our acquisition in 2007, but four years ago, the firm announced its plans to relocate. In 2016, we successfully negotiated a full-building, 30-year lease with NYU Langone, replacing one high credit tenant with another, with virtually no downtime between tenants. We capitalized on this substantial value creation with a sale of the property at very attractive pricing early in 2018. Having accomplished our value creation objectives for the property, this transaction provided the capital to invest in future growth opportunities. One of the most significant opportunities for value creation is through development, and we took a significant stride into this arena in 2018. We commenced our first ground-up development last year with a highly experienced joint venture partner, Normandy Real Estate Partners, on an exciting project in Manhattan’s Midtown South. Together, we are constructing an architecturally striking, 182,000-square-foot boutique office building at the convergence of Union Square and Greenwich Village, neighborhoods that have very few new office buildings available today. We’re already experiencing strong demand for this unique property, which is scheduled to be completed by late 2020. We have expanded our value creation efforts and our partnership with Normandy through a second project that we have under contract as of the writing of this letter. 5 Columbia Property Trust | Annual Report 2018 Columbia Property Trust | Annual Report 2018 6Growing Value through Partnerships and DevelopmentColumbia’s most significant acquisition in 2018 is on the rise. Together with Normandy Real Estate Partners, a highly experienced New York City developer, we have already begun work to develop a new boutique office building at the convergence of Union Square and Greenwich Village, two of Manhattan’s most desirable and storied neighborhoods. We are highly confident this building will be yet another value creator for our stockholders, with its striking exterior and host of best-in-class amenities and features: • 182,000 square feet of loft-style office and retail space• 15’ ceilings and floor-to-ceiling windows• Multiple private terraces• Attractively-sized floor plates, from 3,600 to 22,000 square feet• Spectacular skyline viewsColumbia Property Trust | Annual Report 20187In a joint venture transaction scheduled to close later this year, we and Normandy will acquire 250 Church Street, a 235,000-square-foot office building in Manhattan’s hip TriBeCa neighborhood – another highly desirable neighborhood with very little competing office space. We are working with our partner on a comprehensive plan to redevelop and reposition this building into a boutique-style, best-in-class office experience that will appeal to the area’s artistic, affluent community, and we look forward to sharing more details on this project in the months ahead.Maintaining Financial FlexibilityThrough every step forward, we’ve always emphasized the importance of a strong balance sheet, characterized by low leverage, at flexible terms and attractive interest rates. After using most of the proceeds from our 2018 dispositions to pay down debt, we further enhanced our balance sheet late in the year with an amendment and restatement of our credit facility.This beneficial transaction expanded our credit facility by $150 million while successfully extending our debt maturities and lowering the borrowing costs on our bank debt. We ended the year with a debt-to-EBITDA ratio of 6.1 times and no debt maturities for the next two years. We also demonstrated our continuing faith in the underlying value of our portfolio through $70 million of opportunistic share repurchases in 2018.A Continued Focus on Growth Looking ahead to 2019, we expect our core assets to continue to perform well while we seek additional opportunities to create stockholder value. We will continue to make the most of our future lease expirations and limited remaining vacant space to capture increases in net effective rental rates. Despite being 97% leased, we expect strong same-store NOI growth again in 2019, thanks to our continued leasing success.And we plan to finalize our portfolio’s move into gateway, CBD markets. We are currently pursuing dispositions of the three properties we still own that are located in non-gateway markets, two in Atlanta and one in Pittsburgh. These sales are subject to pricing and market conditions, but if all three are closed successfully as we anticipate, we will have a portfolio concentrated in New York, San Francisco and Washington, D.C., as well as a property each in Boston and greater Los Angeles.Because our portfolio is now well-leased, our investment activities this year will be focused on new value-add opportunities, like the properties we’ve previously targeted and successfully repositioned – attractive and well-located buildings that offer an opportunity to increase cash flows and value through more attentive management and leasing. Alongside this, we also intend to selectively explore further re-development and construction projects, as well as opportunities to cost-effectively expand our platform and portfolio by aligning with joint venture partners. Columbia Property Trust | Annual Report 2018 88E. Nelson MillsPresident, Chief Executive Officer and DirectorMarch 28, 2019“Our focus is on making the right decisions for our portfolio and our operations that will deliver long-term growth and enhanced value for our stockholders. “We are always mindful of how our cash flow is impacted by investing in projects that offer strong growth potential but require a longer time horizon – especially when the capital has been recycled out of properties that are currently producing income. Selling our noncore properties will decrease our FFO modestly this year, but we believe our planned new investments will deliver significant earnings growth in the years ahead, to complement the solid performance of our core portfolio. We will continue to be discerning and disciplined in our capital allocation decisions as we advance our strategy and create more growth going forward.As always, our focus is on making the right decisions for our portfolio and our operations that will deliver long-term growth and enhanced value for our stockholders. Columbia Property Trust is now the strongest it’s ever been. We are excited to see our strategy deliver the expected results and look forward to pursuing new avenues toward even greater value creation and growth. Thank you for continuing this journey with us.FORM 10-K UNITED STATES SECURITIES AND EXCHANGE COMMISSION Washington, D.C. 20549 _______________________________________________ FORM 10-K _______________________________________________ (mark one) Annual report pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 for the fiscal year ended December 31, 2018 OR Transition report pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 for the transition period from ______ to ______ Commission file number 001-36113 COLUMBIA PROPERTY TRUST, INC.

BUSINESS General PART I Columbia Property Trust, Inc. ("Columbia Property Trust") (NYSE: CXP) is a Maryland corporation that operates as a real estate investment trust ("REIT") for federal income tax purposes and owns and operates commercial real estate properties. Columbia Property Trust was incorporated in 2003, commenced operations in 2004, and conducts business primarily through Columbia Property Trust Operating Partnership, L.P. ("Columbia Property Trust OP"), a Delaware limited partnership. Columbia Property Trust is the general partner and sole owner of Columbia Property Trust OP and possesses full legal control and authority over its operations. Columbia Property Trust OP acquires, develops, redevelops, owns, leases, and operates real properties directly, through wholly owned subsidiaries, and through unconsolidated joint ventures. Unless otherwise noted, references to Columbia Property Trust, "we," "us," or "our" herein shall include Columbia Property Trust and all subsidiaries of Columbia Property Trust, direct and indirect. We typically acquire, develop, or redevelop high-quality, income-generating office properties located in certain high-barrier-to- entry markets. As of December 31, 2018, we owned 18 operating properties and two properties under development or redevelopment, of which 14 were wholly owned and six were owned through unconsolidated joint ventures. These properties are located primarily in New York, San Francisco, Washington, D.C., and Atlanta, contain a total of 8.9 million rentable square feet, and were approximately 97.4% leased as of December 31, 2018. Real Estate Investment Objectives We seek to acquire, develop, or redevelop and manage a commercial real estate portfolio that provides the size, quality, and market specialization needed to deliver both income and long-term growth, as measured in the total return to our stockholders. Our primary strategic objective is to generate long-term stockholder returns from a combination of steadily growing cash flows and appreciation in our net asset values, through the acquisition and ownership of high-quality office buildings located principally in high-barrier- to-entry markets. Our value creation and growth strategies are founded in the following: Targeted Market Strategy Our portfolio consists of a combination of multi- and single-tenant office properties located primarily in Central Business Districts ("CBD"). We focus our acquisition efforts in select primary markets with strong fundamentals and liquidity, including CBD and urban in-fill locations. We believe that the major U.S. office markets provide the greatest opportunity for increasing net income and property values over time. We maintain a long-term goal of increasing our presence in our target markets in order to leverage our scale, efficiency, and market knowledge. New Investment Targets We look to acquire, develop, or redevelop strategic and premier office assets with quality tenants in our target markets. We concentrate on office buildings that are competitive within the top tier of their markets or that can be repositioned as such through value-add initiatives. In addition, our investment objectives include optimizing our portfolio allocation between stabilized investments and more growth-oriented, value-add investments, with an emphasis on CBDs and multi-tenant buildings. Strong and Flexible Balance Sheet We are committed to maintaining an investment-grade balance sheet with a strong liquidity profile and proven access to capital. Our leverage level and other credit metrics provide the financial flexibility to pursue new acquisitions and other growth opportunities that will further our long-term performance objectives. Capital Recycling To date, we have primarily sold non-strategic assets (generally, defined as assets outside our target markets) to increase our concentration in our target markets. In the future, we also anticipate selling some assets from our target markets to maintain a well-balanced portfolio and to harvest capital from mature assets. Our goals are to foster long-term growth and capital appreciation in our portfolio by maintaining the following: an appropriate balance of core investments relative to value-add investments, building profiles that will continue to attract prospects for future rent growth, and activity levels that will continue to support our connections in the real estate community. We routinely evaluate our portfolio to identify assets that are good candidates for disposition in the furtherance of these goals. Page 4 Proactive Asset Management We believe our team is well-equipped to deliver operating results in all facets of the management process. Our leasing efforts are founded in understanding the varied and complex needs of tenants in the marketplace today. We pursue meeting those needs through new and renewal leases, as well as lease restructures that further our long-term goals. We are committed to prudent capital investment in our assets to ensure their competitive positioning and status, and rigorously pursue efficient operations and cost containment at the property level. Transaction Activity In connection with repositioning our portfolio, and in furtherance of our real estate investment objectives, we have executed the following real estate transactions during 2018, 2017, and 2016.

(3) Sale price is for the partial interests in the properties. After partial sale, these properties are owned through unconsolidated joint ventures. Please refer to Note 3, Real Estate Transactions, and Note 4, Unconsolidated Joint Ventures, of the accompanying consolidated financial statements for more information. Segment Information As of December 31, 2018, our reportable segments are determined based on high-barrier-to-entry markets and other geographic markets in which we have significant investments. We consider geographic location when evaluating our portfolio composition and in assessing the ongoing operations and performance of our properties. See Note 15, Segment Information, to the accompanying consolidated financial statements. Employees As of December 31, 2018, we employed 95 people. Competition Leasing real estate is highly competitive in the current market. As a result, we experience competition for high-quality tenants from owners and managers of competing projects. Therefore, we may experience delays in re-leasing vacant space, or we may have to provide rent concessions, incur charges for tenant improvements, or offer other inducements to enable us to timely lease vacant space, all of which may have an adverse impact on our results of operations. In addition, we are in competition with other potential buyers for the acquisition of the same properties, which may result in an increase in the amount we must pay to purchase a property. Further, at the time we elect to dispose of our properties, we will also be in competition with sellers of similar properties to locate suitable purchasers. Concentration of Credit Risk We are dependent upon the ability of our tenants to pay their contractual rent amounts as they become due. The inability of a tenant to pay future rental amounts could result in a material adverse impact on our results of operations. We are not aware of any reason why our current tenants would not be able to pay their contractual rental amounts as they become due in all material respects. Based on our 2018 annualized lease revenue, no single tenant accounts for more than 6% of our portfolio.

RISK FACTORS Below are some of the risks and uncertainties that could cause our actual results to differ materially from those presented in our forward-looking statements. The risks and uncertainties described below are not the only ones we face but do represent those risks and uncertainties that we believe are material to our business, operating results, prospects, and financial condition. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also harm our business. Risks Related to Our Business and Properties If we are unable to find suitable investments or they become too expensive, we may not be able to achieve our investment objectives, and the returns on our investments will be lower than they otherwise would be; if we are unable to sell a property when we plan to do so, our operational and financial flexibility may become limited, including our ability to pay cash distributions to our stockholders. We are competing for real estate investments with other REITs; real estate limited partnerships; pension funds and their advisors; bank and insurance company investment accounts; individuals; non U.S. investors; and other entities. The market for high-quality commercial real estate assets is highly competitive, given how infrequently those assets become available for purchase. As a result, many real estate investors, including us, face aggressive competition to purchase quality office real estate assets. A significant number of entities and resources competing for high-quality office properties support relatively high acquisition prices for such properties, which may reduce the number of acquisition opportunities available to, or affordable for, us and could put pressure on Page 6 our profitability and our ability to pay distributions to stockholders. We cannot be sure that we will be successful in obtaining suitable investments with financially attractive terms or that, if we make investments, our objectives will be achieved. Because real estate investments are relatively illiquid, our ability to promptly sell one or more properties in our portfolio in response to changing economic, financial, and investment conditions may be limited. Purchasers may not be willing to pay acceptable prices for properties that we wish to sell. General economic conditions, availability of financing, interest rates, capitalization rates, and other factors, including supply and demand, all of which are beyond our control, affect the real estate market. Therefore, we may be unable to sell a property for the price, on the terms, or within the time frame that we want. That inability could reduce our cash flow and cause our results of operations to suffer, limiting our ability to make distributions to our stockholders. Additionally, our properties' market values depend principally upon the value of the properties' leases and the net operating income generated by the leases. A property may incur vacancies either by the default of tenants under their leases or the expiration of tenant leases. If vacancies occur and continue for a prolonged period of time, it may become difficult to locate suitable buyers for any such property, and property resale values may suffer, which could result in lower returns for our stockholders. Further, timing differences in our acquisitions and dispositions may create temporary fluctuations in our earnings and cash available for distribution to stockholders. Economic conditions may cause the creditworthiness of our tenants to deteriorate and occupancy and market rental rates to decline. Although U.S. macroeconomic conditions continued to be relatively stable during 2018, several economic factors, including increases in interest rates, may adversely affect the financial condition and liquidity of many businesses, as well as the demand for office space generally. Should economic conditions worsen, our tenants' ability to honor their contractual obligations may suffer. Further, it may become increasingly difficult to maintain our occupancy rate and achieve future rental rates comparable to the rental rates of our currently in-place leases as we seek to re-lease space and/or renew existing leases. Our office properties were approximately 97.4% leased at December 31, 2018, and provisions for uncollectible tenant receivables, net of recoveries, were less than 0.1% of total revenues for the year then ended. As a percentage of 2018 annualized lease revenue, approximately 3% of leases expire in 2019, 6% of leases expire in 2020, and 16% of leases expire in 2021 (see Item 2, Properties). No assurances can be given that economic conditions will not have a material adverse effect on our ability to re-lease space at favorable rates or on our ability to maintain our current occupancy rate and our low provisions for uncollectible tenant receivables. Changes in general economic conditions and regulatory matters germane to the real estate industry may cause our operating results to suffer and the value of our real estate properties to decline. Our operating results are subject to risks generally incident to the ownership of real estate, including: • • • • • • • • changes in general or local economic conditions; changes in supply of or demand for similar or competing properties in an area; changes in interest rates and availability of permanent mortgage funds, which may render the sale of a property difficult or unattractive; inability to finance property development or acquisitions on favorable terms; the relative illiquidity of real estate investments; changes in space utilization by our tenants due to technology, economic conditions, and business culture; changes in tax, real estate, environmental, and zoning laws; and periods of rising or higher interest rates and tight money supply. These and other reasons may prevent us from being profitable or from realizing growth or maintaining the value of our real estate properties. We are dependent upon the economic climates of our markets – New York; San Francisco; Washington, D.C.; Boston; Los Angeles; and Atlanta. In addition, market and economic conditions in the metropolitan areas in which we derive a substantial portion of our revenue such as New York, San Francisco, Washington, D.C., Boston, and Atlanta, may have a significant impact on our overall occupancy levels and rental rates and, therefore, our profitability. Furthermore, our business strategy involves continued focus on select core markets, which will increase the impact of the local economic conditions in such markets on our results of operations in future periods. These and other reasons may prevent us from being profitable or from realizing growth or maintaining the value of our real estate properties. Page 7 We depend on tenants for our revenue, and lease defaults or terminations, particularly by a significant tenant, could negatively affect our financial condition and results of operations and limit our ability to make distributions to our stockholders. The success of our investments materially depends on the financial stability of our tenants. A default or termination by a significant tenant on its lease payments to us would cause us to lose the revenue associated with such lease and require us to find an alternative source of revenue to meet debt payments and prevent a foreclosure if the property is subject to a mortgage, could cause us to violate our bank debt covenants, or could impact our credit rating. In the event of a tenant default or bankruptcy, we may experience delays in enforcing our rights as landlord and may incur substantial costs in protecting our investment and re-letting our property. If a tenant defaults on or terminates a significant lease, we may be unable to lease the property for the rent previously received or sell the property without incurring a loss. In addition, significant expenditures for our properties and our company, such as real estate taxes, insurance and maintenance costs, together with general and administrative costs and debt payments, do not decrease when revenues decrease. Therefore, these events could have a material adverse effect on our results of operations or cause us to reduce the amount of distributions to stockholders. As of December 31, 2018, no more than 6% of our 2018 annualized lease revenue was attributable to any individual tenant. In the future, however, we may have a significant tenant who does account for more than 6% of our 2018 annualized lease revenue, and accordingly, any event of bankruptcy, insolvency, or a general downturn in the business of such tenant may result in the failure or delay of the tenant's rental payments, which may have a substantial adverse effect on our operating performance. Future acquisitions may fail to perform in accordance with our expectations, may require renovation costs exceeding our estimates or expose us to unknown liabilities, and may be located in new markets where we may face risks associated with investing in an unfamiliar market. In the normal course of business, we typically evaluate potential acquisitions, enter into nonbinding letters of intent, and may, at any time, enter into contracts to acquire, develop, or redevelop additional properties. Our properties may fail to perform in accordance with our expectations due to lease-up risk, renovation cost risks, and other factors. In addition, the renovation and improvement costs we incur to bring a property up to market standards may exceed our estimates. We may not have the financial resources to make suitable acquisitions or renovations on favorable terms or at all. The properties we acquire, develop, or redevelop may be subject to liabilities for which we have no recourse, or only limited recourse, against the prior owners or other third parties with respect to unknown liabilities. As a result, if a liability were asserted against us based upon ownership of those properties, we might have to pay substantial sums to settle or contest it, which could adversely affect our results of operations and cash flow. Unknown liabilities with respect to our properties might include: • • • • liabilities for clean-up of undisclosed environmental contamination; claims by tenants, vendors, or other persons against the former owners of the properties; liabilities incurred in the ordinary course of business; and claims for indemnification by general partners, directors, officers, and others indemnified by the former owners of the properties. Furthermore, we may acquire, develop, or redevelop properties located in markets in which we do not have an established presence. We may face risks associated with a lack of market knowledge or understanding of the local economy, forging new business relationships in the area, and unfamiliarity with local government and permitting procedures. As a result, the operating performance of properties acquired, developed, or redeveloped in new markets may be less than we anticipate, and we may have difficulty integrating such properties into our existing portfolio. In addition, the time and resources that may be required to obtain market knowledge and/or integrate such properties into our existing portfolio could divert our management's attention from our existing business or other attractive opportunities in our established markets. Uninsured losses relating to real property or excessively expensive premiums for insurance coverage could reduce our net income, and materially and adversely affect our business or financial condition. We may incur losses from time to time that are uninsurable or not economically feasible to insure, or may be insured subject to limitations, such as large deductibles or co-payments. Some of these losses could be catastrophic in nature, such as losses due to earthquakes, acts of terrorism, fire, floods, tornadoes, hurricanes, pollution, wars, or environmental matters. For example, we have properties located in San Francisco, California, an area especially susceptible to earthquakes, and, collectively, these properties represent approximately 26% of our 2018 annualized lease revenue, as described in Item 2, Properties. Because several of these properties are located in close proximity to one another, an earthquake in the San Francisco area could materially damage, destroy, or impair the use by tenants of all of these properties. Furthermore, insurance risks associated with potential terrorist acts could sharply increase the premiums we pay for coverage against property and casualty claims. Additionally, mortgage lenders in some cases insist that commercial property owners purchase coverage against terrorism as a condition of providing mortgage loans. Such insurance policies may not be available at a reasonable cost, if at all, which could inhibit our ability to finance or refinance our properties. In such instances, we may be required to provide other financial support, either through financial assurances or Page 8 self-insurance, to cover potential losses. In addition, we may not have adequate coverage for losses. If any of our properties incur a loss that is not fully insured, the value of that asset will be reduced by such uninsured loss. Furthermore, other than any working capital reserves or other reserves that we may establish, or our existing line of credit, we do not have additional sources of funding specifically designated for repairs or reconstruction of any our properties. To the extent we incur significant uninsured losses, or are required to pay unexpectedly large amounts for insurance, our results of operations or financial condition could be adversely affected. If we are unable to fund the future capital needs of our properties, cash distributions to our stockholders and the value of our investments could decline. When tenants do not renew their leases or otherwise vacate their space, we often need to expend substantial funds for tenant improvements to the vacated space in order to attract replacement tenants. In addition, although we expect that our leases with tenants will require tenants to pay routine property maintenance costs, we will likely be responsible for any major structural repairs, such as repairs to the foundation, exterior walls, and rooftops. If we need significant capital in the future to improve or maintain our properties or for any other reason, we will have to obtain financing from sources such as cash flow from operations, borrowings, property sales, or future equity offerings. These sources of funding may not be available on attractive terms or at all. If we cannot procure the necessary funding for capital improvements, our investments may generate lower cash flows or decline in value, or both, which would limit our ability to make distributions to our stockholders. We have incurred and may continue to incur indebtedness, which may increase our business risks. As of February 4, 2019, our total consolidated indebtedness was approximately $1.3 billion, which includes a $150.0 million term loan and $700.0 million of bonds with fixed interest rates, or with interest rates that are effectively fixed when considered in connection with an interest rate swap agreement; and $498.0 million in outstanding borrowings on our line of credit, with a variable interest rate. We may incur additional indebtedness to acquire, develop, or redevelop properties, to fund property improvements and other capital expenditures, to pay our distributions, and for other purposes. Significant borrowings by us increase the risks of an investment in us. If there is a shortfall between the cash flow from properties and the cash flow needed to service our indebtedness, then the amount available for distributions to stockholders may be reduced. In addition, incurring mortgage debt increases the risk of loss since defaults on indebtedness secured by a property may result in lenders initiating foreclosure actions. In that case, we could lose the property securing the loan that is in default. If any of our properties are foreclosed due to a default, our ability to pay cash distributions to our stockholders will be limited. For tax purposes, a foreclosure of any of our properties would be treated as a sale of the property for a purchase price equal to the outstanding balance of the debt secured by the mortgage. If the outstanding balance of the debt secured by the mortgage exceeds our tax basis in the property, we would recognize taxable income on foreclosure, but we would not receive any cash proceeds. We may give full or partial guarantees to lenders of mortgage debt on behalf of the entities that own our properties. When we give a guaranty on behalf of an entity that owns one of our properties, we are responsible to the lender for satisfaction of the debt if it is not paid by such entity. If any indebtedness contains cross-collateralization or cross-default provisions, a default on a single loan could affect multiple properties. Our unsecured credit facility (the "Revolving Credit Facility") and our two unsecured term loan facilities each include a cross-default provision that provides that a payment default under any recourse obligation of $50 million or more by us, Columbia Property Trust OP, or any of our subsidiaries, constitutes a default under the line of credit and term loan facilities. Increases in interest rates could increase the amount of our debt payments and make it difficult for us to refinance our unsecured bank debt or bonds, or to finance or refinance properties, which could reduce the number of properties we can acquire, develop, or redevelop, our net income, and the amount of cash distributions we can make. We expect to incur additional indebtedness in the future, which may include term loans, borrowings under a credit facility, unsecured bonds, or mortgages. Increases in interest rates will increase interest costs on our variable-interest debt instruments, which would reduce our cash flows and our ability to pay distributions. If mortgage debt is unavailable at reasonable interest rates, we may not be able to finance the purchase of properties. If we place mortgage debt on properties, we run the risk of being unable to refinance the properties when the loans become due, or of being unable to refinance on favorable terms. In addition, if we need to repay existing debt during periods of higher interest rates, we may need to sell one or more of our investments in order to repay the debt, which sale at that time might not permit realization of the maximum return on such investments. Our variable-interest debt instruments may use London Interbank Offering Rate (“LIBOR”) as a benchmark for establishing the rate. LIBOR is the subject of recent national, international and other regulatory guidance and proposals for reform. These reforms and other pressures may cause LIBOR to disappear entirely or to perform differently than in the past. The consequences of these Page 9 developments cannot be entirely predicted but could include an increase in the cost of our variable-interest debt instruments. If LIBOR is no longer widely available, or otherwise at our option, our Revolving Credit Facility and term loan facilities provide for alternate interest rate calculations. If any of these events occur, our cash flow would be reduced. This, in turn, would reduce cash available for distribution to our stockholders and may hinder our ability to raise capital in the future through additional borrowings or debt or equity offerings. For additional information, please refer to Item 7A, Quantitative and Qualitative Disclosures about Market Risk, for additional information regarding interest rate risk. Lenders may require us to enter into restrictive covenants relating to our operations, which could limit our ability to make distributions to our stockholders. When providing financing, a lender may impose restrictions on us that affect our distribution and operating policies and our ability to incur additional debt. Loan documents we enter into may contain covenants that limit our ability to further mortgage the property or discontinue insurance coverage. These or other limitations may limit our flexibility and our ability to execute on our operating plans. A downgrade in the credit rating of our debt could materially adversely affect our business and financial condition. Our senior unsecured debt is rated investment grade by Standard & Poor's Corporation and Moody's Investors Service. In determining our credit ratings, the rating agencies consider a number of both quantitative and qualitative factors, including earnings, fixed charges, cash flows, total debt outstanding, total secured debt, off balance sheet obligations, total capitalization, and various ratios calculated from these factors. The rating agencies also consider predictability of cash flows, business strategy, joint venture activity, property development risks, industry conditions, and contingencies. Therefore, any deterioration in our operating performance could cause our investment-grade rating to come under pressure. Our corporate credit rating at Standard & Poor's Ratings Service is currently "BBB" with a stable outlook, and our corporate credit rating at Moody's Investor Service is currently "Baa2" with a stable outlook. There can be no assurance that our credit ratings will not be lowered or withdrawn in their entirety. A negative change in our ratings outlook or any downgrade in our current investment-grade credit ratings by rating agencies could adversely affect our cost and access to sources of liquidity and capital. Additionally, a downgrade could, among other things, increase the costs of borrowing under our credit facility and term loans, adversely impact our ability to obtain unsecured debt or refinance our unsecured debt on competitive terms in the future, or require us to take certain actions to support our obligations, any of which would adversely affect our business and financial condition. We face risks relating to the occurrence of cyber incidents, or a deficiency in our cybersecurity, which could negatively impact our business by causing a disruption to our operations, a compromise of confidential information, and/or damage to our business relationships. A cyber incident is considered to be any adverse event that threatens the confidentiality, integrity, or availability of our information resources. More specifically, a cyber incident is an intentional attack or an unintentional event that can include gaining unauthorized access to systems to disrupt operations, corrupt data, or steal confidential information. A breach of our privacy or information security systems or our tenants' privacy or information security systems, particularly through cyber attacks or cyber intrusion, could materially adversely affect our business and financial condition. Privacy and information security risks have generally increased in recent years because of the proliferation of new technologies and the increased sophistication and activities of perpetrators of cyber attacks. As our reliance on technology has increased, so have the risks of cyber attacks to our systems, both internal and those we have outsourced. Cyber attacks can be both individual and highly organized attempts planned by very sophisticated hacking organizations. Risks that could directly result from the occurrence of a cyber incident include operational interruption, damage to our relationships with our tenants, potential errors from misstated financial reports, missed reporting deadlines, and private data exposure, among others. Any or all of the preceding risks could have a material adverse effect on our results of operations, financial condition, and cash flows. We employ a number of measures to prevent, detect, and mitigate these threats, which include dual factor authentication, frequent password change events, firewall detection systems, frequent backups, a redundant data system for core applications and annual breach testing. While, to date, we have not had a significant cyber breach or attack that has had a material impact on our business or results of operations, there can be no assurance that our efforts to maintain the security and integrity of our systems will be effective, or that we will be able to maintain our systems free from security breaches or other operational interruptions. A cybersecurity attack could compromise the confidential information of our employees, customers, and vendors. A successful attack could disrupt and affect our business operations, damage our reputation, and result in significant remediation and litigation costs. Further, one or more of our tenants could experience a cyber incident which could impact their operations and ability to perform under the terms of their lease with us. While we maintain insurance coverage that may, subject to policy terms and conditions including deductibles, cover specific aspects of cyber risks, such insurance coverage may be insufficient to cover all Page 10 losses. As cyber threats continue to evolve, we may be required to expend additional resources to continue to enhance our information security measures and to investigate and remediate any information security vulnerabilities. We are and may continue to be subject to litigation, which could have a material adverse effect on our financial condition. We currently are, and are likely to continue to be, subject to a variety of claims arising in the ordinary course of business. Such claims could include personal injury claims, contract claims, and claims alleging violations of federal and state law regarding workplace and employment matters, discrimination, and similar matters. Some of these claims may result in significant defense costs and potentially significant judgments against us, some of which are not, or cannot be, insured against. Although we defend ourselves against any such claims, we cannot be certain of the ultimate outcomes of currently asserted claims or of those that arise in the future. Resolution of these types of matters against us may result in our having to pay significant fines, judgments, or settlements, which, if uninsured, or if the fines, judgments, and settlements exceed insured levels, would adversely impact our earnings and cash flows, thereby impacting our ability to service debt and make distributions to our stockholders. Costs of complying with governmental laws and regulations may reduce our net income and the cash available for distributions to our stockholders. All real property and the operations conducted on real property are subject to federal, state, and local laws and regulations relating to environmental protection and human health and safety. Some of these laws and regulations may impose joint and several liability on tenants, owners, or operators for the costs to investigate or remediate contaminated properties, regardless of fault or whether the acts causing the contamination were legal. In addition, the presence of hazardous substances, or the failure to properly remediate these substances, may hinder our ability to sell, rent, or pledge such property as collateral for future borrowings. Compliance with new laws or regulations, or stricter interpretation of existing laws, may require us to incur material expenditures. Future laws, ordinances, or regulations may impose material environmental liability. Additionally, our tenants' operations, the existing condition of land when we buy it, operations in the vicinity of our properties, such as the presence of underground storage tanks or activities of unrelated third parties may affect our properties. Furthermore, there are various local, state, and federal regulatory requirements, such as fire, health, life-safety, and similar regulations, and the Americans with Disabilities Act, with which we may be required to comply, and which may subject us to liability in the form of fines or damages for noncompliance. Any material expenditures, fines, or damages we must pay would adversely impact our earnings and cash flows, thereby impacting our ability to service debt and make distributions to our stockholders. Compliance or failure to comply with the Americans with Disabilities Act or other safety regulations and requirements could result in substantial costs. The Americans with Disabilities Act generally requires that certain buildings, including office buildings, be made accessible to disabled persons. Noncompliance could result in the imposition of fines by the federal government or the award of damages to private litigants. If, under the Americans with Disabilities Act, we are required to make substantial alterations and capital expenditures in one or more of our properties, including the removal of access barriers, it could adversely impact our earnings and cash flows, thereby impacting our ability to service debt and make distributions to our stockholders. Our properties are subject to various federal, state, and local regulatory requirements, such as state and local fire and life safety requirements. If we fail to comply with these requirements, we could incur fines or private damage awards. We do not know whether existing requirements will change or whether compliance with future requirements will require significant unanticipated expenditures that will affect our cash flow and results of operations. Discovery of previously undetected environmentally hazardous conditions may decrease our revenues and limit our ability to make distributions. Under various federal, state, and local environmental laws, ordinances, and regulations, a current or previous real property owner or operator may be liable for the cost to remove or remediate hazardous or toxic substances on, under, or in such property. These costs could be substantial. Such laws often impose liability whether or not the owner or operator knew of, or was responsible for, the presence of such hazardous or toxic substances. Environmental laws also may impose restrictions on the manner in which property may be used or businesses may be operated, and these restrictions may require substantial expenditures or prevent us from entering into leases with prospective tenants that may be impacted by such laws. Environmental laws provide for sanctions for noncompliance and may be enforced by governmental agencies or, in certain circumstances, by private parties. Certain environmental laws and common law principles could be used to impose liability for release of and exposure to hazardous substances, including asbestos-containing materials. Third parties may seek recovery from real property owners or operators for personal injury or property damage associated with exposure to released hazardous substances. The cost of defending against claims of liability, of complying with environmental regulatory requirements, of remediating any contaminated property, or of paying personal injury claims could have an adverse impact on our business and results of operations. Page 11 Property ownership through joint ventures may limit our ability to act exclusively in our interest. We have entered into six joint venture arrangements and in the future may acquire, develop, or redevelop properties in, or contribute properties to, joint ventures with other persons or entities when we believe circumstances warrant the use of such structures. We could become engaged in a dispute with one or more of our joint venture partners, which might affect our ability to operate a jointly owned property. Moreover, joint venture partners may have business, economic, or other objectives that are inconsistent with our objectives, including objectives that relate to the appropriate timing and terms of any sale or refinancing of a property. In some instances, joint venture partners may have competing interests in our markets that could create conflicts of interest. Also, our joint venture partners might refuse to make capital contributions when due, and we may be responsible to our partners for indemnifiable losses. We and our partners may each have the right to trigger a buy-sell arrangement, which could cause us to sell our interest, or acquire our partners' interest, at a time when we otherwise would not have initiated such a transaction and may result in the valuation of our interest in the joint venture (if we are the seller) or of the other partner's interest in the joint venture (if we are the buyer) at levels which may not be representative of the valuation that would result from an arm's length marketing process. We are also subject to the following risks, the likelihood of which may be higher when our joint venture partner is an institutional owner and required to aggregate approvals from multiple beneficial owners: (i) a deadlock if we and our joint venture partner are unable to agree upon certain major and other decisions, (ii) the limitation of our ability to liquidate our position in the joint venture without the consent of the other joint venture partner, and (iii) the requirement to provide guarantees in favor of lenders with respect to the indebtedness of the joint venture. If we sell properties and provide financing to purchasers, defaults by the purchasers would decrease our cash flows and limit our ability to make distributions. In some instances we may sell our properties by providing financing to purchasers. When we provide financing to purchasers, we will bear the risk that the purchaser may default, which could negatively impact our liquidity and results of operations. Even in the absence of a purchaser default, the distribution of the proceeds of sales to our stockholders, or the reinvestment of proceeds in other assets, will be delayed until the promissory notes or other property we may accept upon a sale are actually paid, sold, refinanced, or otherwise disposed. We are dependent on our executive officers and employees. We rely on a small number of persons, particularly E. Nelson Mills and James A. Fleming, to carry out our business and investment strategies. Any of our senior management, including Messrs. Mills and Fleming, may cease to provide services to us at any time. The loss of the services of any of our key management personnel or our inability to recruit and retain qualified personnel in the future, could have an adverse effect on our business and financial results. We will continue to try to attract and retain qualified additional senior management and other employees, but may not be able to do so on acceptable terms. We face risks associated with property development or redevelopment. We may acquire and develop or redevelop properties, including unimproved real estate, upon which we will construct improvements. Such activities present a number of risks for us, including risks that: • • • • • • • if we are unable to obtain all necessary zoning and other required governmental permits and authorizations or cease development of the project for any other reason, the development opportunity may be abandoned or postponed after expending significant resources, resulting in the loss of deposits or failure to recover expenses already incurred; the development and construction costs of the project may exceed original estimates due to increased interest rates and increased cost of materials, labor, leasing or other expenditures, which could make the completion of the project less profitable because market rents may not increase sufficiently to compensate for the increase in construction costs; construction and/or permanent financing may not be available on favorable terms or may not be available at all, which may cause the cost of the project to increase and lower the expected return; the project may not be completed on schedule, or at all, as a result of a variety of factors, many of which are beyond our control, such as weather, labor conditions, and material shortages, which would result in increases in construction costs and debt service expenses; if a contractor's performance is affected or delayed by conditions beyond the contractor's control, we may incur additional risks when we make periodic progress payments or other advances to contractors before they complete construction; the time between commencement of a development project and the stabilization of the completed property exposes us to risks associated with fluctuations in local and regional economic conditions; and occupancy rates and rents at the completed property may not meet the expected levels and could be insufficient to make the property profitable. Properties developed or acquired for development or redevelopment may generate little or no cash flow from the date of acquisition Page 12 through the date of completion of development. In addition, new development activities, regardless of whether or not they are ultimately successful, may require a substantial portion of management's time and attention. These risks could result in substantial unanticipated delays or expenses and, under certain circumstances, could prevent completion of development activities once undertaken. Any of the foregoing could have an adverse effect on our financial condition, results of operations or ability to satisfy our debt service obligations. If our disclosure controls or internal control over financial reporting are not effective, investors could lose confidence in our reported financial information, which could adversely affect the perception of our business and the trading price of our common stock. Section 404 of the Sarbanes-Oxley Act of 2002 requires that we evaluate the effectiveness of our internal control over financial reporting as of the end of each fiscal year and to include a management report assessing the effectiveness of our internal control over financial reporting. Deficiencies, including any material weakness, in our internal control over financial reporting that may occur in the future could result in misstatements of our results of operations, restatements of our financial statements, a decline in the trading price of our common stock, or otherwise materially adversely affect our business, reputation, results of operations, financial condition, or liquidity. Risks Related to Ownership of Our Common Stock We may be unable to pay or maintain cash distributions or increase distributions over time, which could reduce the funds we have available for investment and the return to our investors. There are many factors that can affect the availability and timing of distributions to stockholders. We expect to continue to fund distributions principally from cash flow from operations; however, from time to time, we may elect to fund a portion of our distributions from borrowings. If we fund distributions from financings, we will have fewer funds available for the investment in, and acquisition of, properties; thus, the overall return to our investors may be reduced. We can give no assurance that we will be able to pay or maintain cash distributions or increase distributions over time. Our stock price may be volatile or may decline regardless of our operating performance, and may impede our stockholders' ability to sell their shares at a desirable price. The market price of our common stock may vary significantly in response to a number of factors, most of which we cannot control, including those described under this section and the following: • • • • • • • changes in capital market conditions that could affect valuations of real estate companies in general or other adverse economic conditions; our failure to meet any earnings estimates or expectations; future sales of our common stock by our officers, directors, and significant stockholders; global economic, legal, and regulatory factors unrelated to our performance; investors' perceptions of our prospects; announcements by us or our competitors of significant contracts, acquisitions, joint ventures, or capital commitments; and investor perceptions of the investment opportunity associated with our common stock relative to other investment alternatives. In addition, from time to time, the New York Stock Exchange (the "NYSE"), has experienced extreme price and volume fluctuations that have affected the market prices of equity securities of many real estate companies. In the past, stockholders have instituted securities class action litigation following periods of market volatility. If we were involved in securities litigation, we could incur substantial costs, and our resources and the attention of management could be diverted from our business. Furthermore, we currently have limited research coverage by securities and industry analysts. If additional securities or industry analysts do not commence coverage of our company, the long-term trading price for our common stock could be negatively impacted. If one or more of present or future analysts who cover us downgrade our common stock or publish inaccurate or unfavorable research about our business, our stock price would likely decline. If one or more of these analysts cease coverage of us or fail to publish reports on us regularly, demand for our common stock could decrease, which could cause our stock price and trading volume to decline. Further issuances of equity securities may be dilutive to current stockholders. The interests of our existing stockholders could be diluted if additional equity securities are issued to finance future acquisitions, developments, or redevelopments, or to repay indebtedness. Our ability to execute our business strategy depends on our access to Page 13 an appropriate blend of debt financing, including unsecured lines of credit and other forms of secured and unsecured debt, and equity financing. Our charter limits the number of shares a person may own, which may discourage a takeover that could otherwise result in a premium price to our stockholders. Our charter, with certain exceptions, authorizes our directors to take such actions as are necessary and desirable to preserve our qualification as a REIT. Unless exempted by our board of directors, no person may own more than 9.8% of our outstanding common stock. This restriction may have the effect of delaying, deferring, or preventing a change in control, including an extraordinary transaction (such as a merger, tender offer, or sale of all or substantially all of our assets) that might provide a premium price for holders of our common stock. Our organizational documents contain provisions that may discourage a takeover of us and could depress the price of our shares of common stock. Our organizational documents contain provisions that may discourage a takeover of us and could depress the price of our common stock. Our organizational documents contain provisions that may have an anti-takeover effect, inhibit a change of our management, or inhibit, in certain circumstances, tender offers for our common stock or proxy contests to change our board. These provisions include: ownership limits and restrictions on transferability that are intended to enable us to continue to qualify as a REIT; broad discretion of our board to take action, without stockholder approval, to issue new classes of securities that may discourage a third party from acquiring us; the ability, through board action or bylaw amendment to opt in to certain provisions of Maryland law that may impede efforts to effect a change in control of us; advance notice requirements for stockholder proposals and stockholder nominations of directors; and the absence of cumulative voting rights. In addition, our board of directors may classify or reclassify any unissued preferred stock and establish the preferences; conversion; or other rights, voting powers, restrictions, or limitations as to distributions, qualifications, and terms or conditions of redemption of any such stock. Thus, our board of directors could authorize the issuance of preferred stock with terms and conditions that could have priority as to distributions and amounts payable upon liquidation over the rights of the holders of our common stock. Such preferred stock could also have the effect of delaying, deferring, or preventing a change in control of us, including an extraordinary transaction (such as a merger, tender offer, or sale of all or substantially all of our assets) that might provide a premium price to holders of our common stock. Maryland General Corporation Law provides certain protections relating to deterring or defending hostile takeovers, which may discourage others from trying to acquire control of us and may prevent our stockholders from receiving a premium price for their stock in connection with a business combination. Our board of directors has determined to opt out of certain provisions of Maryland law that may impede efforts to effect a change in control of us as further described below; in the case of the business combination provisions of Maryland law, by resolution of our board of directors; in the case of the control share provisions of Maryland law, pursuant to a provision in our bylaws; and in the case of certain provisions of the Maryland Unsolicited Takeover Act, pursuant to Articles Supplementary. Only upon stockholder approval of an amendment to our Articles of Incorporation may our board of directors repeal the foregoing opt-outs from the anti- takeover provisions of Maryland General Corporation Law. Under Maryland law, "business combinations" between a Maryland corporation and certain interested stockholders or affiliates of interested stockholders are prohibited for five years after the most recent date on which the interested stockholder becomes an interested stockholder. These business combinations include a merger, consolidation, share exchange, or, in circumstances specified in the statute, an asset transfer or issuance or reclassification of equity securities. Also under Maryland law, control shares of a Maryland corporation acquired in a control share acquisition have no voting rights except to the extent approved by a vote of two- thirds of the votes entitled to be cast on the matter. Shares owned by the acquirer, an officer of the corporation, or an employee of the corporation who is also a director of the corporation are excluded from the vote on whether to accord voting rights to the control shares. These provisions may therefore discourage others from trying to acquire control of us and increase the difficulty of consummating any offer. Similarly, provisions of Title 3, Subtitle 8 of the Maryland General Corporation Law, commonly referred to as the "Maryland Unsolicited Takeover Act," could provide similar anti-takeover protection. Federal Income Tax Risks Failure to qualify as a REIT would reduce our net income and cash available for distributions. Our qualification as a REIT depends upon our ability to meet requirements regarding our organization and ownership, distributions of our income, the nature and diversification of our income and assets, and other tests imposed by the Internal Revenue Code (the "Code"). If we fail to qualify as a REIT for any taxable year, we will be subject to federal and state income tax on our taxable Page 14 income at corporate rates, including interest and any applicable penalties. In addition, we would generally be disqualified from treatment as a REIT for the four taxable years following the year of losing our REIT status. Losing our REIT status would reduce our net earnings available for investment or distribution to stockholders because of the additional tax liability. In addition, distributions to stockholders would no longer qualify for the dividends-paid deduction, and we would no longer be required to make distributions. If this occurs, we might be required to borrow funds or liquidate some investments in order to pay the applicable tax. Recharacterization of sale-leaseback transactions may cause us to lose our REIT status, which would reduce the return to our stockholders. We may purchase properties and lease them back to the sellers of such properties. While we will use our best efforts to structure any such sale-leaseback transaction such that the lease will be characterized as a "true lease," thereby allowing us to be treated as the owner of the property for federal income tax purposes, we can give no assurance that the Internal Revenue Service will not challenge such characterization. In the event that any such sale-leaseback transaction is challenged and recharacterized as a financing transaction or loan for federal income tax purposes, deductions for depreciation and cost recovery relating to such property would be disallowed. If a sale-leaseback transaction were so recharacterized, we might fail to satisfy the REIT qualification asset tests or income tests and, consequently, lose our REIT status. Alternatively, the amount of our REIT taxable income could be recalculated, which might also cause us to fail to meet the distribution requirement for a taxable year. Even if we qualify as a REIT for federal income tax purposes, we may be subject to other tax liabilities that reduce our cash flow and our ability to make distributions to our stockholders. Even if we remain qualified as a REIT for federal income tax purposes, we may be subject to some federal, state, and local taxes on our income or property. For example: • In order to qualify as a REIT, we must distribute annually at least 90% of our REIT taxable income to our stockholders (which is determined without regard to the dividends-paid deduction or net capital gain). To the extent that we satisfy the distribution requirement but distribute less than 100% of our REIT taxable income, we will be subject to federal and state corporate income tax on the undistributed income. • We will be subject to a 4% nondeductible excise tax on the amount, if any, by which distributions we pay in any calendar year are less than the sum of 85% of our ordinary income, 95% of our capital gains net income, and 100% of our undistributed income from prior years. • • If we have net income from the sale of foreclosure property that we hold primarily for sale to customers in the ordinary course of business or other nonqualifying income from foreclosure property, we must pay a tax on that income at the highest corporate income tax rate. If we sell a property, other than foreclosure property, that we hold primarily for sale to customers in the ordinary course of business, our gain would be subject to the 100% "prohibited transaction" tax. • We may perform additional, noncustomary services for tenants of our buildings through our taxable REIT subsidiary, including real estate or non-real-estate-related services; however, any earnings related to such services are subject to federal and state income taxes. Legislative or regulatory action could adversely affect investors. In recent years, numerous legislative, judicial, and administrative changes have been made in the provisions of federal and state income tax laws applicable to investments similar to an investment in our shares. In particular, the comprehensive tax reform legislation enacted in December 2017 and commonly known as the Tax Cuts and Jobs Act, or TCJA, makes many significant changes to the U.S. federal income tax laws that will profoundly impact the taxation of individuals and corporations (including both regular C corporations and corporations that have elected to be taxed as REITs). A number of changes that affect noncorporate taxpayers will expire at the end of 2025 unless Congress acts to extend them. These changes will impact us and our stockholders in various ways, some of which are adverse or potentially adverse compared to prior law. Although the IRS has issued guidance with respect to certain of the new provisions, there are numerous interpretive issues that will require further guidance. It is highly likely that technical corrections legislation will be needed to clarify certain aspects of the new law and give proper effect to Congressional intent. There can be no assurance, however, that technical clarifications or changes needed to prevent unintended or unforeseen tax consequences will be enacted by Congress in the near future. Additional changes to tax laws are likely to continue to occur in the future, and we cannot assure investors that any such changes will not adversely affect the taxation of our stockholders. Any such changes could have an adverse effect on an investment in shares or on the market value or the resale potential of our properties. Investors are urged to consult with their own tax advisor with respect to the impact of recent legislation on ownership of shares and the status of legislative, regulatory, or administrative developments and proposals, and their potential effect on ownership of shares. Page 15 To maintain our REIT status, we may be forced to borrow funds or dispose of assets during unfavorable market conditions to make distributions to our stockholders, which could increase our operating costs and decrease the value of an investment in us. We intend to make distributions to our stockholders to comply with the requirements of the Code for REITs and to minimize or eliminate our corporate tax obligations; however, differences between the recognition of taxable income and the actual receipt of cash could require us to sell assets or borrow funds on a short-term or long-term basis to meet the distribution requirements of the Code. Certain types of assets generate substantial disparity between taxable income and available cash, such as real estate that has been financed through financing structures which require some or all of available cash flows to be used to service borrowings. In addition, changes made by TCJA will require us to accrue certain income for U.S. federal income tax purposes no later than when such income is taken into account as revenue on our financial statements (subject to an exception for certain income that is already subject to a special method of accounting under the Internal Revenue Code). This could cause us to recognize taxable income prior to the receipt of the associated cash. TCJA also includes limitations on the deductibility of certain compensation paid to our executives, certain interest payments, and certain net operating loss carryforwards, each of which could potentially increase our taxable income and our required distributions. As a result, the requirement to distribute a substantial portion of our taxable income could cause us to: (1) sell assets in adverse market conditions, (2) borrow on unfavorable terms, or (3) distribute amounts that would otherwise be invested in future acquisitions, capital expenditures, or repayment of debt, in order to comply with REIT requirements. Any such actions could increase our costs and reduce the value of our common stock. Further, we may be required to make distributions to our stockholders when it would be more advantageous to reinvest cash in our business or when we do not have funds readily available for distribution. Compliance with REIT qualification requirements may, therefore, hinder our ability to operate solely on the basis of maximizing profits. To maintain our REIT status, we may be forced to forego otherwise attractive opportunities, which could delay or hinder our ability to meet our investment objectives and lower the return to our stockholders. To qualify as a REIT, we must satisfy tests on an ongoing basis concerning, among other things, the sources of our income, the nature of our assets, and the amounts we distribute to our stockholders. We may be required to make distributions to stockholders at times when it would be more advantageous to reinvest cash in our business or when we do not have funds readily available for distribution. Compliance with the REIT requirements may hinder our ability to operate solely on the basis of maximizing profits. ITEM 1B. UNRESOLVED STAFF COMMENTS Not applicable. ITEM 2. PROPERTIES Overview As of December 31, 2018, we owned 18 operating properties and two properties under development or redevelopment, of which 14 were wholly owned and six were owned through unconsolidated joint ventures. These properties are located primarily in New York, San Francisco, Washington, D.C., and Atlanta and were approximately 97.4% leased as of December 31, 2018. Property Statistics The tables below include statistics for the 13 consolidated operating properties, which we own directly, and our proportional share of the annualized lease revenue and rentable square feet for the five operating properties we own through unconsolidated joint ventures. 2018 annualized lease revenue is an operating metric, calculated as (i) annualized rental payments (defined as base rent plus operating expense reimbursements, excluding rental abatements) for executed and commenced leases as of December 31, 2018, as well as leases executed but not yet commenced for vacant space that will commence within 12 months, and (ii) annualized parking revenues, payable either under the terms of an executed lease or vendor contract ("2018 Annualized Lease Revenue"). 2018 Annualized Lease Revenue excludes rental payments for executed leases that have not yet commenced for space covered by an existing lease.

MARKET FOR REGISTRANT'S COMMON EQUITY, RELATED STOCKHOLDER MATTERS, AND ISSUER PURCHASES OF EQUITY SECURITIES Market Information and Holders Our common stock was listed on the NYSE, on October 10, 2013 under the symbol "CXP." As of January 31, 2019, we had approximately 116.9 million shares of common stock outstanding held by approximately 46,000 stockholders of record. Distributions We intend to make distributions each taxable year (not including a return of capital for federal income tax purposes) equal to at least 90% of our taxable income. One of our primary goals is to pay regular quarterly distributions to our stockholders. The amount of distributions paid and the taxable portion thereof in prior periods are not necessarily indicative of amounts anticipated in future periods. The amount of distributions to common stockholders is determined by our board of directors and is dependent upon a number of factors, including funds deemed available for distribution, based principally on our current and future projected operating cash flows reduced by capital requirements necessary to maintain our existing portfolio, our future capital needs, our future sources of liquidity, and the annual distribution requirements necessary to maintain our status as a REIT under the Code. Investments in new property acquisitions and first-generation capital improvements, as well as equity repurchases, are generally funded with recycled capital proceeds from property sales, debt, or cash on hand. Our board of directors maintained a $0.20 dividend for each quarter of 2018, as well as for the first quarter of 2019. Page 19 Performance Graph The following graph compares the cumulative total return of our common stock with the S&P 500 Index, Morgan Stanley REIT Index, the FTSE NAREIT US Real Estate Index, and the FTSE NAREIT Equity Office Index for the period beginning on October 10, 2013 (the date of our initial listing on the NYSE) through December 31, 2018.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS The following discussion and analysis should be read in conjunction with the Selected Financial Data in Item 6, Selected Financial Data, above and our accompanying consolidated financial statements and notes thereto. See also Cautionary Note Regarding Forward-Looking Statements preceding Part I. Executive Summary Our primary strategic objective is to generate long-term stockholder returns from a combination of growing cash flows and appreciation in the values of our properties, by acquiring, developing, or redeveloping, and operating high-quality office properties located in certain high-barrier-to-entry markets. Our approach is to own office buildings that are competitive within the top tier of their markets or that will be repositioned as such through value-add initiatives. In addition, our investment objectives include optimizing our portfolio allocation between stabilized investments and more growth-oriented, value-add investments, with an emphasis on central business districts and multi-tenant buildings. Over the past several years, we have undertaken a capital recycling program that involved selling more than 50 properties in geographically dispersed markets for aggregate proceeds of $3.6 billion and reinvesting this capital in New York, San Francisco, Washington, D.C., and Boston. In May 2018, we sold 222 East 41st Street in New York after re-leasing the property to a single tenant for 30 years. In October 2018, we acquired a 49.7% interest in a joint venture that will develop a 12-story, 182,000-square- foot office building at 799 Broadway in New York. We are continuing to pursue other strategic investment opportunities in our target markets, as well as selective property dispositions in non-target markets. Leasing continues to be a key area of focus for both vacant space and upcoming expirations. During 2018, we leased 1.1 million square feet of space, including: • • • a 215,000-square-foot, five-year lease extension through 2030 with Twitter for their space at 249 West 17th Street in New York; a 115,000-square-foot, long-term lease with WeWork for the entire office portion of 149 Madison in New York; and lease expansions totaling 199,000 square feet with Arby's Restaurant Group, a subsidiary of Inspire Brands, at One & Three Glenlake Parkway in Atlanta, resulting in a full-building lease of Three Glenlake Parkway, as well as extending the total 359,000-square-foot lease through March 2033. We continue to maintain a strong and flexible balance sheet. In 2018, we amended and restated our $500 million unsecured revolving credit facility and $300 million unsecured term loan, resulting in a $950 million combined credit facility. As further described in the Liquidity and Capital Resources section below, the amended and restated facility extends maturities, lowers interest costs and increases the unsecured revolving credit facility from $500 million to $650 million. Further, the new $300 million term loan is currently undrawn and includes a delayed-draw feature, which allows for up to 12 months to fully draw the term loan. As of December 31, 2018, our debt-to-real-estate-asset ratio is 32.7%(1)(2); 92%(1) of our portfolio is unencumbered by mortgages; and our weighted average cost of borrowing is 3.85%(1) per annum. Our debt maturities are laddered over the next eight years, and $632.0 million of our unsecured borrowings can be repaid prior to maturity without penalty. From time to time when we believe our stock is undervalued, we may take advantage of market opportunities by using our stock repurchase program to buy shares and return capital to our stockholders. During 2018, we repurchased $70.4 million of our common stock (3.2 million shares at an average price of $21.73 per share). (1) Statistics include our ownership interest in the gross real estate assets and debt at properties held through unconsolidated joint ventures as described in Note 4, Unconsolidated Joint Ventures, of the accompanying financial statements. (2) On a net basis (i.e., reduced for cash on hand), our debt-to-real-estate-asset ratio is 31.9%. Page 23 Key Performance Indicators Our operating results depend primarily upon the level of income generated by the leases at our properties. Occupancy and rental rates are critical drivers of our lease income. Over the last year, our portfolio percentage leased ranged from 96.2% at December 31, 2017 to 97.4% at December 31, 2018. The following table sets forth details related to the financial impact of our recent leasing activities for properties we own directly and based on our proportionate share of properties owned through unconsolidated joint ventures: Total number of leases Square feet of leasing – renewal Square feet of leasing – new Total square feet of leasing Average lease term (months) Tenant improvements, per square foot – renewal Tenant improvements, per square foot – new Tenant improvements, per square foot – all leases Leasing commissions, per square foot – renewal Leasing commissions, per square foot – new Leasing commissions, per square foot – all leases Rent leasing spread – renewal(1) Rent leasing spread – new(1) Rent leasing spread – all leases(1) Years Ended December 31, 2018 2017 59 505,612 567,288 1,072,900 $ $ $ $ $ $ 122 28.53 82.29 66.29 24.04 27.56 26.51 11.6% 34.4% 23.1% 62 1,288,056 716,513 2,004,569 103 20.17 85.55 55.09 12.37 27.76 20.59 28.2% 63.3% 43.6% $ $ $ $ $ $ (1) Rent leasing spreads are calculated based on the change in base rental income measured on a straight-line basis; and, for new leases, only include space that has been vacant for less than one year. In 2018, rent leasing spreads were positive (23.1%) primarily due to a lease extension with Twitter for 215,000 square feet at 249 West 17th Street and lease expansions for an aggregate of 199,000 square feet with Arby's Restaurant Group, a subsidiary of Inspire Brands, at One & Three Glenlake Parkway in Atlanta. In 2018, tenant improvements include $115.00 per square foot for a new, 16.5-year lease with WeWork for 115,000 square feet at 149 Madison Avenue, which will entail a full-scale redevelopment of the property. In 2017, rent leasing spreads were significantly positive (43.6%) due to extending the 119,000-square-foot lease with DLA Piper at University Circle in San Francisco and leasing 230,000 square feet at 650 California Street in San Francisco. The leasing at 650 California Street required significant tenant improvements; however, the net economic impact of the leasing at 650 California Street is favorable. Positive rent leasing spreads in 2017 for renewal leases were partially offset by a slight rent roll-down for the 824,000-square-foot lease extension and amendment executed with Westinghouse at Cranberry Woods in Pittsburgh. Liquidity and Capital Resources Overview Cash flows generated from the operation of our properties are primarily used to fund recurring expenditures and stockholder dividends. The amount of distributions to common stockholders is determined by our board of directors and is dependent upon a number of factors, including funds deemed available for distribution based principally on our current and future projected operating cash flows, reduced by capital requirements necessary to maintain our existing portfolio, our future capital needs, and future sources of liquidity, as well as the annual distribution requirements necessary to maintain our status as a REIT under the Code. Investments in new property acquisitions and first-generation capital improvements are generally funded with capital proceeds from property sales, debt, or cash on hand. Our board of directors elected to maintain a $0.20 dividend rate for fourth quarter of 2018, as well as for the first quarter of 2019. Short-Term Liquidity and Capital Resources During 2018, we generated net cash flows from operating activities of $97.6 million, which consists primarily of receipts from tenants for rent and reimbursements, reduced by payments for operating costs, administrative expenses, interest expense, and lease inducements. During the same period, we paid total distributions to stockholders of $95.1 million, which included dividend Page 24 payments for four quarters ($23.9 million for the fourth quarter of 2017 and an aggregate of $71.2 million for the first three quarters of 2018). During 2018, we sold 222 East 41st Street and an additional 22.5% interest in the 333 Market Street and University Circle joint ventures for aggregate net proceeds of $519.7 million. We used these proceeds to pay down $293.2 million of debt; to invest $157.6 million in real estate assets, including those held in unconsolidated joint ventures; and to repurchase $70.4 million of our common stock. Over the short term, we expect our primary sources of capital and liquidity to be operating cash flows, select property dispositions, and debt. We expect that our principal demands for funds will be property acquisitions, capital improvements to our existing portfolio, stockholder distributions, stock repurchases, operating expenses, and interest and principal payments. As of February 4, 2019, we have access to $152.0 million under our Revolving Credit Facility and $300.0 million under our delayed-draw term loan. We believe that we will have adequate liquidity and capital resources to meet our current obligations as they come due. Long-Term Liquidity and Capital Resources Over the long term, we expect that our primary sources of capital will include operating cash flows, select property dispositions, and borrowing proceeds. We expect that our primary uses of capital will continue to include stockholder distributions; acquisitions; capital expenditures, such as building improvements, tenant improvements, and leasing costs; and repaying or refinancing debt. Consistent with our financing objectives and operational strategy, over the long term we have generally maintained debt levels less than 40% of the undepreciated costs of our assets. As of December 31, 2018, our debt-to-real-estate-asset ratio was approximately 32.7%. Our debt-to-real-estate-asset ratio includes our share of joint venture real estate assets and debt, as well as basis adjustments related to joint venture real estate assets. As described below, our variable rate indebtedness may use London Interbank Offering Rate (“LIBOR”) as a benchmark for establishing the rate. LIBOR is the subject of recent national, international and other regulatory guidance and proposals for reform. These reforms and other pressures may cause LIBOR to disappear entirely or to perform differently than in the past. The consequences of these developments cannot be entirely predicted but could include an increase in the cost of our variable rate indebtedness. If LIBOR is no longer widely available, or otherwise at our option, our Revolving Credit Facility and term loan facilities provide for alternate interest rate calculations. Unsecured Bank Debt On December 7, 2018, we amended and restated our $500 million unsecured revolving credit facility and $300 million unsecured term loan with a $950 million combined credit facility. As further described below, the new facility extends maturities, lowers interest costs, and increases the unsecured revolving credit facility from $500 million to $650 million. Concurrent with closing, we repaid the $300 million outstanding balance on the old $300 million term loan. As of December 31, 2018, the new $300 million term loan remained undrawn and includes a delayed-draw feature, which allows us up to 12 months to fully draw the term loan. Our Revolving Credit Facility has a capacity of $650.0 million and matures in January 2023, with two six-month extension options. As of December 31, 2018, we had $482.0 million in outstanding borrowings on the Revolving Credit Facility. Amounts outstanding under the Revolving Credit Facility bear interest at the London Interbank Office Rate ("LIBOR"), plus an applicable margin ranging from 0.775% to 1.45% for LIBOR borrowings, or an alternate base rate, plus an applicable margin ranging from 0.00% to 0.45% for base rate borrowings, based on our applicable credit rating. The per annum facility fee on the aggregate revolving commitment (used or unused) ranges from 0.125% to 0.30%, also based on our applicable credit rating. Additionally, the Revolving Credit Facility, along with the $300 Million Term Loan, as described below, provides for four accordion options for an aggregate additional amount of up to $500 million, subject to certain limitations. Our $300.0 million unsecured term loan matures in January 2024 (the "$300 Million Term Loan") and bears interest, at our option, at either (i) LIBOR, plus an applicable margin ranging from 0.85% to 1.65% for LIBOR loans, or (ii) an alternate base rate, plus an applicable margin ranging from 0.00% to 0.65% for base rate loans, based on our applicable credit rating. The per annum facility fee on the aggregate term loan commitment (used or unused) ranges from 0.125% to 0.30%, also based on our applicable credit rating. As of December 31, 2018, the $300 Million Term Loan remained undrawn with no amounts outstanding. Our $150.0 million unsecured term loan matures in July 2022 (the "$150 Million Term Loan") and bears interest, at our option, at either (i) LIBOR, plus an applicable margin ranging from 0.90% to 1.75% for LIBOR loans, or (ii) alternative base rate, plus an applicable margin ranging from 0.00% to 0.75% for base rate loans. The interest rate on the $150 Million Term Loan is effectively fixed with an interest rate swap agreement, which is designated as a cash flow hedge. Based on the terms of the interest rate swap and our current credit rating, the interest rate on the $150 Million Term Loan is effectively fixed at 3.07%. Page 25 Debt Covenants As of December 31, 2018, the $300 Million Term Loan, the $150 Million Term Loan, and the Revolving Credit Facility contain the following restrictive covenants, which are defined in the debt agreements: • • • • • limit the ratio of secured debt to total asset value to 40% or less; require the fixed charge coverage ratio to be at least 1.50:1.00; limit the ratio of debt to total asset value to 60% or less, or 65% or less following a material transaction; require the ratio of unencumbered interest coverage ratio to be at least 1.75:1.00; limit the unencumbered leverage ratio to 60% or less, or 65% or less following a material transaction. As of December 31, 2018, we were in compliance with the restrictive covenants on these outstanding debt obligations. Bonds Payable In August 2016, we issued $350.0 million of 10-year, unsecured 3.650% senior notes at 99.626% of their face value (the "2026 Bonds Payable"). The 2026 Bonds Payable require semi-annual interest payments in February and August based on a contractual annual interest rate of 3.650%. The principal amount of the 2026 Bonds Payable is due and payable on the maturity date, August 15, 2026. In March 2015, we issued $350.0 million of 10-year, unsecured 4.150% senior notes at 99.859% of their face value (the "2025 Bonds Payable"). The 2025 Bonds Payable require semi-annual interest payments in April and October based on a contractual annual interest rate of 4.150%. The principal amount of the 2025 Bonds Payable is due and payable on the maturity date, April 1, 2025. The restrictive covenants on the 2026 Bonds Payable and the 2025 Bonds Payable as defined pursuant to an indenture include: • • • • a limitation on the ratio of debt to total assets, as defined, to 60%; limits to our ability to incur debt if the consolidated income available for debt service to annual debt service charge, as defined, for four previous consecutive fiscal quarters is less than 1.50:1:00 on a pro forma basis; limits to our ability to incur liens if, on an aggregate basis for us, the secured debt amount would exceed 40% of the value of the total assets; and a requirement that the ratio of unencumbered asset value, as defined, to total unsecured debt be at least 150% at all times. As of December 31, 2018, we were in compliance with the restrictive covenants on the 2026 Bonds Payable and the 2025 Bonds Payable. Debt Settlements and Interest Payments During 2018, we made the following debt repayments: • On December 14, 2018, we terminated both the $120.0 million development authority bonds and the corresponding obligations under capital leases related to One & Three Glenlake Parkway in Atlanta. • On December 7, 2018, concurrent with closing on the amendment and restatement of our term loan and revolving credit facility, we repaid the $300 million remaining balance on the $300 Million Term Loan, which includes a delayed-draw feature, allowing up to 12 months to fully draw the term loan. • On October 10, 2018, we paid the $20.7 million outstanding balance on the One Glenlake mortgage note two months prior to its original maturity date. • On April 13, 2018, we transferred 263 Shuman Boulevard to the lender in extinguishment of the $49.0 million loan principal, accrued interest expense, and accrued property operating expenses, which resulted in a gain on extinguishment of debt of $24.0 million in the second quarter of 2018. • On February 2, 2018, we repaid $120.0 million of the outstanding balance on the $300 Million Bridge Loan with disposition proceeds from the sale of a portion of University Circle and 333 Market Street. On May 30, 2018, we repaid the remaining $180.0 million outstanding balance on the $300 Million Bridge Loan with disposition proceeds from the sale of 222 East 41st Street. The settlement of the $300 Million Bridge Loan resulted in a $0.3 million loss on extinguishment of debt to write off the related unamortized deferred financing costs. During 2018, we made interest payments of approximately $22.1 million related to our term loans, line of credit, and notes payable, and $27.3 million related to our bonds payable. Page 26 Contractual Commitments and Contingencies As of December 31, 2018, our contractual obligations will become payable in the following periods (in thousands): Contractual Obligations Debt obligations(1) Interest obligations on debt(1)(2) Operating lease obligations(3) Total 2019 2020-2021 2022-2023 Thereafter $ 1,547,983 $ — $ 50,233 $ 797,750 $ 318,620 1,363,648 59,646 8,442 118,459 17,124 87,227 17,388 700,000 53,288 1,320,694 Total $ 3,230,251 $ 68,088 $ 185,816 $ 902,365 $ 2,073,982 (1) (2) Includes our ownership share of the debt and interest obligations for the Market Square Joint Venture and the 799 Broadway Joint Venture, which we own through unconsolidated joint ventures. The Market Square Joint Venture has a $325.0 million mortgage loan on the Market Square Buildings, which bears interest at 5.07% and matures on July 1, 2023. We own a 51% interest in the Market Square Joint Venture. The 799 Broadway Joint Venture has $101.1 million outstanding on a construction loan, which has a total capacity of $187.0 million; bears interest at LIBOR, capped at 4.00%, plus 4.25%; and matures on October 9, 2021. We own a 49.7% interest in the 799 Broadway Joint Venture. As of December 31, 2018, we guarantee $5.8 million of the Market Square Buildings mortgage loan, and under the 799 Broadway construction loan agreement, we guarantee equity contributions of $25.3 million to be made to the joint venture (see Note 7, Commitments and Contingencies, to the accompanying financial statements). Interest obligations on variable-rate debt are measured at the rate at which they are effectively fixed with interest rate swap agreements (where applicable) or the rate in effect as of December 31, 2018. Interest obligations on all other debt instruments are measured at the contractual rate. See Item 7A, Quantitative and Qualitative Disclosures about Market Risk, for more information regarding our interest rate swaps. (3) These obligations are related to ground leases at certain properties, including 49.5% of the ground lease obligation at 114 Fifth Avenue, based on our ownership interest in the unconsolidated joint venture that owns that property, and our corporate office lease. In addition to the amounts shown, certain lease agreements include provisions that, at the option of the tenant, may obligate us to expend capital to expand an existing property or provide other expenditures for the benefit of the tenant. Results of Operations Overview As of December 31, 2018, we owned 18 operating properties and two properties under development or redevelopment, of which 14 were wholly owned and six were owned through unconsolidated joint ventures. These properties are located primarily in New York, San Francisco, Washington, D.C., and Atlanta, and were approximately 97.4% leased as of December 31, 2018. Our period- over-period operating results are heavily impacted by the real estate activities set forth in the "Transaction Activity" section of Item 1, Business, including acquisitions and dispositions made directly and through unconsolidated joint ventures. Other than real estate transactions, we expect real estate operating income to vary, primarily based on leasing activity over the near term. Comparison of the Year Ended December 31, 2018 Versus the Year Ended December 31, 2017 Rental income and tenant reimbursements were $283.3 million for 2018, which represents a slight increase as compared with $280.6 million for 2017. The additional revenues from acquisitions ($33.5 million) and leasing ($18.1 million) are offset by the impacts of transferring University Circle and 333 Market Street to unconsolidated joint ventures in the third quarter of 2017 ($33.1 million) and dispositions ($15.8 million). We expect future rental income to vary based on recent and future investing and leasing activities. Hotel income, net of hotel operating costs, was $(0.8) million for 2017. The Key Center Marriott was sold on January 31, 2017. Asset and property management fee income was $7.4 million for 2018, which represents an increase as compared with $3.8 million for 2017. In the current year, we provided asset and property management services to the Market Square Joint Venture, the San Francisco Joint Ventures, and the 1800 M Street Joint Venture. For the first half of 2017, we only provided management services to the Market Square Joint Venture; effective July 1, 2017, we began to also provide management services to the San Francisco Joint Ventures. We anticipate asset and property management fee income to remain at similar levels in the near term. Other property income was $7.3 million for 2018, which represents an increase as compared with $3.3 million for 2017, primarily due to providing additional reimbursable services to our unconsolidated joint ventures ($2.1 million) and lease termination activity ($1.7 million). Other property operating income is expected to vary in the future, based on additional future joint venture activities and lease restructurings. Property operating costs were $88.8 million for 2018, which represents a slight increase from $87.8 million for 2017. The impacts of acquired properties with primarily gross leases ($6.7 million) are offset by transferring University Circle and 333 Market Street Page 27 to unconsolidated joint ventures in the third quarter of 2017 ($5.6 million). Property operating costs are expected to vary with future leasing activity and changes in our portfolio. Asset and property management fee expenses were $0.9 million for both 2018 and 2017. There was a slight decrease due to expenses incurred in 2017 for the Key Center Marriott which was sold in January 2017 ($0.1 million). Future asset and property management fee expenses are expected to remain stable in the near term and may increase as a result of future investing activities. Depreciation was $81.8 million for 2018, which represents a slight increase as compared with $80.4 million for 2017. The impacts of additional depreciation from acquisitions ($8.1 million) and from the completion of capital and tenant improvement projects across the portfolio ($4.6 million) are offset by the impacts of transferring University Circle and 333 Market Street to unconsolidated joint ventures in the third quarter of 2017 ($8.4 million), and dispositions ($3.0 million). Depreciation is expected to vary based on recent and future investing activities and capital projects. Amortization was relatively stable at $32.6 million for 2018 and $32.4 million for 2017. The impact of acquisitions ($5.7 million) is offset by transferring University Circle and 333 Market Street to unconsolidated joint ventures in July 2017 ($2.7 million), prior- period lease expirations and terminations ($2.1 million), and dispositions ($0.9 million). We expect future amortization to vary, based on recent and future investing and leasing activities. For 2018, we recognized an impairment loss of $30.8 million in connection with changing our holding period expectations for 222 East 41st Street in the second quarter of 2018. Future impairment losses will depend primarily on our holding period intentions and any disposition strategies evaluated for our other properties. Total general and administrative expenses were relatively stable at $36.1 million for 2018 and $36.4 million for 2017. Effective July 1, 2017, we began to allocate certain general and administrative expenses to unconsolidated joint ventures based on the time incurred to manage assets owned by our unconsolidated joint ventures. We expect future general and administrative expenses to remain at similar levels in the near term. Interest expense was $56.5 million for 2018, which represents a decrease as compared with $60.5 million for 2017. The decrease is due to mortgage loan repayments ($6.3 million) and interest capitalization activity ($3.3 million), offset by increased outstanding amounts on our unsecured borrowings throughout the current year ($5.7 million). We expect interest expense to vary based on future investing activities. We recognized a gain on extinguishment of debt of $23.3 million for 2018, and a loss on extinguishment of debt of $0.3 million for 2017. In April 2018, we transferred 263 Shuman Boulevard to the lender in extinguishment of the related mortgage note, resulting in a $24.0 million gain on extinguishment of debt. In May 2018, we repaid the remaining outstanding balance on our bridge loan approximately six months early, resulting in a $0.3 million loss due to the write-off of related deferred financing costs; and in December 2018, we refinanced two of our debt facilities, resulting in a $0.3 million loss due to the write-off of related deferred financing costs. In 2017, we repaid two mortgage notes prior to maturity, resulting in the write-off of an aggregate of $0.3 million related to deferred financing costs. We expect future gains or losses on extinguishments of debt to vary with financing activities. Interest and other income was $6.9 million for 2018, which represents a decrease as compared with $9.5 million for 2017. The decrease is due to interest income earned on additional cash deposits held in 2017 ($2.3 million). The majority of this income was earned on investments in development authority bonds, which were used to settle a corresponding capital lease obligation in December 2018. Interest income earned on investments in development authority bonds was entirely offset by interest expense incurred on the corresponding capital leases. Interest income is expected to decrease as a result of the development authority bonds. We recognized a gain on sale of unconsolidated joint venture interests of $0.8 million for 2018, related to the sale of an additional 22.5% interest in University Circle and 333 Market Street joint ventures in February 2018, as further described in Note 3, Real Estate Transactions, to the accompanying consolidated financial statements. We expect future gains or losses on sales of unconsolidated joint venture interests to vary with future joint venture disposition activities. We recognized income from unconsolidated joint ventures of $8.0 million for 2018, which represents an increase as compared with $2.7 million for 2017. The increase is due to owning interest in the following operating properties through unconsolidated joint ventures for a full year: University Circle, 333 Market Street, 1800 M Street, and 114 5th Avenue. We expect future income from unconsolidated joint ventures to vary based on future joint venture investing activities and leasing activity at properties owned through unconsolidated joint ventures. We recognized gains on sales of real estate assets of $175.5 million in 2017, as a result of selling three properties in Houston, Texas, and the Key Center Tower and Marriott in Cleveland, Ohio in January 2017; and selling a 22.5% interest in each of the University Circle property and the 333 Market Street building in July 2017. See Note 3, Real Estate Transactions, of the Page 28 accompanying financial statements, for additional details of these dispositions. We expect future gains on sales of real estate assets to vary with disposition activity. Net income was $9.5 million, or $0.08 per basic and diluted share, for 2018, which represents a decrease as compared with $176.0 million, or $1.45 per basic and diluted share, for 2017. The decrease is primarily due to prior-period gains on sales of real estate assets ($175.5 million). See the "Supplemental Performance Measures" section below for our same-store results compared with the prior year. We expect future earnings to vary primarily as a result of leasing activity at our existing properties and future investing activity. Comparison of the Year Ended December 31, 2017 Versus the Year Ended December 31, 2016 Rental income and tenant reimbursements were $280.6 million for 2017, which represents a decrease from $436.0 million for 2016. The decrease is primarily due to dispositions ($129.8 million), transferring University Circle and 333 Market Street to unconsolidated joint ventures ($29.3 million), and the new net lease at 222 East 41st Street ($3.3 million), partially offset by the acquisitions in the fourth quarter of 2017 ($8.4 million). Hotel income, net of hotel operating costs, was $(0.8) million for 2017, which represents a decrease as compared with $4.0 million for 2016, due to the sale of the Key Center Marriott on January 31, 2017. Asset and property management fee income was $3.8 million for 2017, which represents an increase as compared with $2.1 million for 2016. The increase is due to the asset and property management services we began to provide to several properties owned in unconsolidated joint ventures in 2017, including 333 Market Street, University Circle, and 1800 M Street. Asset and property management fees have also been earned for services provided to the Market Square Joint Venture since its inception in the fourth quarter of 2015. Other property income was $3.3 million for 2017, which represents a decrease as compared with $12.8 million for 2016, primarily due to earning an early termination fee of $6.8 million at 222 East 41st Street in June 2016 and $4.0 million for other lease terminations in 2016. The terminated lease at 222 East 41st Street was replaced with a full-building lease, which commenced in the fourth quarter of 2016. Property operating costs were $87.8 million for 2016, which represents a decrease from $155.0 million for 2016. The decrease is primarily due to dispositions ($58.3 million), the new net lease at 222 East 41st Street ($9.9 million), and transferring University Circle and 333 Market Street to unconsolidated joint ventures ($5.5 million), partially offset by the acquisitions in the fourth quarter of 2017 ($2.2 million). Asset and property management fee expenses were $0.9 million for 2017, which represents a decrease as compared with $1.4 million for 2016, primarily due to the sale of the Key Center Marriott in January 2017 ($0.4 million). Depreciation was $80.4 million for 2017, which represents a decrease as compared with $108.5 million for 2016. The decrease is primarily due to dispositions ($24.5 million) and transferring University Circle and 333 Market Street to unconsolidated joint ventures ($6.6 million), partially offset by acquisitions in the fourth quarter of 2017 ($2.3 million). Amortization was $32.4 million for 2017, which represents a decrease as compared with $56.8 million for 2016. The decrease is primarily due to intangibles written off due to the early termination or expiration of leases ($11.1 million), dispositions ($10.9 million), and transferring University Circle and 333 Market Street to unconsolidated joint ventures ($2.5 million). Effective July 1, 2017, we began to specifically identify general and administrative costs incurred to manage assets owned by our unconsolidated joint ventures. The method for measuring aggregate general and administrative expenses has not changed. Aggregate general and administrative expenses were $36.4 million for 2017, which represents an increase as compared to $33.9 million for 2016, primarily due to additional vesting under our stock-based incentive plan ($3.0 million) and expenses incurred for managing unconsolidated joint ventures ($1.5 million), partially offset by prior-year costs incurred related to the development of our regional management platform ($1.2 million), prior-year lease termination activity ($0.5 million), and prior period bad debt expenses ($0.2 million). Interest expense was $60.5 million for 2017, which represents a decrease as compared with $67.6 million for 2016, primarily due to mortgage note payoffs ($5.4 million), bond interest savings resulting from the issuance of the 2026 Bonds Payable and redemption of the 2018 Bonds Payable in 2016 ($2.1 million), and an overall reduction in borrowings on our Revolving Credit Facility in the current period ($1.5 million). We recognized a loss on extinguishment of debt of $0.3 million and $19.0 million in 2017 and 2016, respectively. In 2017, we repaid two mortgage notes prior to maturity, resulting in the write-off of the related deferred financing costs ($0.3 million). In Page 29 2016, we incurred an early redemption premium on the settlement of the 2018 Bonds Payable ($17.9 million), and write-offs of related deferred financing costs ($1.0 million). Interest and other income was $9.5 million for 2017, which represents an increase as compared with $7.3 million for 2016. The increase is due to earning interest on our large cash balance for the first nine months of 2017 ($2.2 million). The majority of our interest income is earned on investments in development authority bonds. Interest income earned on investments in development authority bonds is entirely offset by interest expense incurred on the corresponding capital leases. We recognized income from unconsolidated joint ventures of $2.7 million for 2017, which represents an increase from a loss on unconsolidated joint ventures of $7.6 million for 2016. The increase is due to the July 2017 transfer of University Circle and 333 Market Street to unconsolidated joint ventures, in which we retained a 77.5% ownership interest; the July 2017 acquisition of a 49.5% interest in 114 Fifth Avenue; and the October 2017 acquisition of a 55.0% interest in 1800 M Street. We recognized gains on sales of real estate assets of $175.5 million in 2017, as a result of selling three properties in Houston, Texas, and the Key Center Tower and Marriott in Cleveland, Ohio in January 2017; and selling a 22.5% interest in each of the University Circle property and the 333 Market Street building in July 2017. We recognized gains on sales of real estate assets of $72.3 million in 2016, as a result of selling seven properties in separate transactions during the the year. See Note 3, Real Estate Transactions, of the accompanying financial statements, for additional details of these dispositions. Net income was $176.0 million, or $1.45 per basic and diluted share, for 2017, which represents an increase from $84.3 million, or $0.68 per basic and diluted share, for 2016. The increase is due to gains on sale of real estate ($103.2 million) and financing activities resulting in interest savings in the current year and losses on extinguishment of debt in the prior year ($25.8 million), partially offset by lost income from sold properties ($38.4 million). NOI by Geographic Segment We consider geographic location when evaluating our portfolio composition, and in assessing the ongoing operations and performance of our properties. As of December 31, 2018, we aggregated our properties into the following geographic segments: New York, San Francisco, Atlanta, Washington, D.C., Boston, Los Angeles, and all other office markets. All other office markets consists of properties in low-barrier-to-entry geographic locations, in which we do not have a substantial presence and do not plan to make further investments. See Note 15, Segment Information, to the accompanying consolidated financial statements. The following table presents NOI by geographic segment (in thousands): New York San Francisco Atlanta Washington, D.C.

Atlanta NOI has increased due to leases commencing at One & Three Glenlake Parkway. From December 31, 2017 to December 31, 2018, One & Three Glenlake Parkway's commenced occupancy increased from 88.1% to 100.0%. Page 30 Washington, D.C. NOI has increased as a result of the October 2017 acquisition of a 55.0% interest in 1800 M Street and leasing at Market Square. From December 31, 2017 to December 31, 2018, Market Square's commenced occupancy increased from 78.5% to 84.1%. Boston NOI has increased as a result of leasing at 116 Huntington Avenue. From December 31, 2017 to December 31, 2018, 116 Huntington Avenue's commenced occupancy increased from 77.4% to 89.0%. All Other Office Markets NOI decreased as a result of asset sales in the first quarter of 2017 and the tenant at 263 Shuman Boulevard vacating the property in May 2017. 263 Shuman Boulevard was transferred to the lender in extinguishment of the related mortgage note on April 13, 2018. Comparison of the Year Ended December 31, 2017 versus the Year Ended December 31, 2016 San Francisco NOI has decreased during 2017 due to the sale of a 22.5% interest in both University Circle and 333 Market Street. Washington, D.C. NOI has increased during 2017 due to the October 2017 acquisition of a 55% interest in 1800 M Street, as described in Note 3, Real Estate Transactions, of the accompanying consolidated financial statements, which was partially offset by decreased occupancy at 80 M Street and Market Square in 2017. All other office markets NOI has decreased significantly year over year as a result of asset sales, as described in Note 3, Real Estate Transactions, of the accompanying consolidated financial statements. Hotel The Key Center Marriott, our only hotel, was sold on January 31, 2017. Supplemental Performance Measures In addition to net income, we measure the performance of the company using certain non-GAAP supplemental performance measures, including: (i) Funds From Operations ("FFO"), (ii) Net Operating Income ("NOI"), and (iii) Same Store Net Operating Income ("Same Store NOI"). These non-GAAP metrics are commonly used by industry analysts and investors as supplemental operation performance measures of REITs and are viewed by management to be useful indicators of operating performance. Historical cost accounting for real estate assets in accordance with GAAP implicitly assumes that the value of real estate assets diminishes predictably over time. Since real estate values instead have historically risen or fallen with market conditions, many industry analysts and investors have considered presentation of operating results for real estate companies using historical cost accounting alone to be insufficient. Management believes that the use of FFO, NOI, and Same Store NOI, combined with net income, improves the understanding of operating results of REITs among the investing public and makes comparisons of REIT operating results more meaningful. Net income is the most comparable GAAP measure to FFO, NOI, and Same Store NOI. Each of these supplemental performance measures exclude expenses that materially impact our overall results of operations and, therefore, should not be considered as a substitute for net income, income from continuing operations before income taxes, or any other measures derived in accordance with GAAP. Furthermore, these metrics may not be comparable to other similarly titled measures used by other companies. Funds From Operations FFO is a non-GAAP measure used by many investors and analysts who follow the real estate industry to measure the performance of an equity REIT. We consider FFO a useful measure of our performance principally because it excludes the effects of GAAP depreciation and amortization of real estate assets, which reduce the carrying value of real estate assets systematically over time. Since real estate values have historically risen or fallen with market conditions, we believe that FFO provides a meaningful supplemental measure of our performance. We believe that the use of FFO, combined with the required GAAP presentations, is beneficial in improving our investors' understanding of our operating results and allowing for comparisons among other companies who define FFO as we do. FFO, as defined by the National Association of Real Estate Investment Trusts ("NAREIT"), represents net income (computed in accordance with GAAP), excluding gains or losses on sales of real estate and impairments of real estate assets, plus real estate- Page 31 related depreciation and amortization, after adjustments for unconsolidated partnerships and joint ventures, for both continuing and discontinued operations. We compute FFO in accordance with NAREIT's definition, which may differ from the methodology for calculating FFO, or similarly titled measures, used by other companies, and this may not be comparable to those presentations. FFO does not represent amounts available for management's discretionary use because of needed capital replacement or expansion, debt service obligations, or other commitments and uncertainties, nor is it indicative of funds available to fund our cash needs, including our ability to make distributions. Our presentation of FFO should not be considered as an alternative to net income (computed in accordance with GAAP) as an indicator of financial performance. Net income reconciles to FFO as follows (in thousands): Reconciliation of Net Income to Funds From Operations: Net income Adjustments: Depreciation of real estate assets Amortization of lease-related costs Impairment loss on real estate assets Depreciation and amortization included in loss from unconsolidated joint venture(1) Gain on sale of unconsolidated joint venture interests Gains on sales of real estate assets Total funds from operations adjustments Years Ended December 31, 2018 2017 2016 $ 9,491 $ 176,041 $ 84,281 81,795 32,554 30,812 51,377 (762) — 195,776 80,394 32,403 — 21,288 — (175,518) (41,433) 108,543 56,775 — 8,776 — (72,325) 101,769 186,050 Funds from operations $ 205,267 $ 134,608 $ (1) Reflects our ownership interest in depreciation and amortization for investments in unconsolidated joint ventures. The following significant non-cash revenues and expenses are included in our funds from operations: • Straight-line rental income, net: to recognize rent on a straight-line basis over the lease term, we recognized net straight- line rental income for our wholly-owned properties of $25.9 million, $31.9 million and $20.0 million in 2018, 2017 and 2016, respectively. Income (loss) from unconsolidated joint ventures includes additional net straight-line rental income of $(0.7) million, $(0.7) million, and $2.3 million in 2018, 2017 and 2016, respectively. • Amortization of intangible lease assets and liabilities: to amortize above and below market in-place lease intangible assets (liabilities), we recognized net increases to rental revenues (or decreases to operating expenses) for our wholly- owned properties of $3.2 million, $0.5 million and $4.2 million in 2018, 2017 and 2016, respectively. Income (loss) from unconsolidated joint ventures includes additional net operating income for amortization of intangible lease assets and liabilities of $11.5 million, $2.3 million, and $0.2 million in 2018, 2017 and 2016, respectively. • Gain (loss) on extinguishment of debt: we recognized gains or losses on the repayment of debt before maturity of $23.3 million, $(0.3) million, and $(19.0) million in 2018, 2017, and 2016, respectively. • Amortization of deferred financing costs and debt premiums (discounts): to amortize costs associated with securing debt from third-party lenders over the terms of the respective debt facilities, we recognized net interest expense of $3.1 million, $3.0 million, and $3.5 million for 2018, 2017, and 2016, respectively. Income (loss) from unconsolidated joint ventures includes additional net interest expense of $(1.6) million in 2018. Page 32 Net Operating Income As set forth below, NOI is calculated by deducting property operating costs from rental and other property revenues for continuing operations. As a performance metric consisting of only revenues and expenses directly related to ongoing real estate rental operations, which have been or will be settled in cash, NOI is narrower in scope than FFO. NOI, as we calculate it, may not be directly comparable to similarly titled, but differently calculated, measures for other REITs. We believe that NOI is another useful supplemental performance measure, as it is an input in many REIT valuation models, and it provides a means by which to evaluate the performance of the properties. The major factors influencing our NOI are property acquisitions and dispositions, occupancy levels, rental rate increases or decreases, and the recoverability of operating expenses. Same Store Net Operating Income We also evaluate the performance of our properties, on a "same store" basis, using a metric referred to as Same Store NOI. We view Same Store NOI as a useful supplemental performance measure because it improves comparability between periods by eliminating the effects of changes in the composition of our portfolio. On an individual property basis, Same Store NOI is computed in a consistent manner as NOI (as described in the previous section). For the periods presented, we have defined our same store portfolio as those properties that have been continuously owned and operating since January 1, 2017. NOI and Same Store NOI are calculated as follows for the years ended December 31, 2018 and 2017 (in thousands): Same-Store NOI – wholly owned properties: Revenues: Rental income and tenant reimbursements Other property income Total revenues Operating expenses Same Store NOI – wholly owned properties(1) Same Store NOI – joint-venture owned properties(2) Total Same Store NOI NOI from acquisitions(3) NOI from dispositions(4) NOI Years Ended December 31, 2018 2017 $ $ 233,466 $ 7,293 240,759 (78,203) 162,556 52,879 215,435 49,907 6,157 271,499 $ 215,459 3,214 218,673 (72,920) 145,753 39,470 185,223 10,792 32,860 228,875 (1) Reflects NOI from properties that were wholly owned for the entirety of the periods presented.

Same Store NOI increased from $185.2 million for 2017 to $215.4 million for 2018, primarily as a result of leasing vacant space at 650 California Street in San Francisco, and at Market Square and 80 M Street in Washington, D.C.

Page 34 Portfolio Information As of December 31, 2018, we owned 18 operating properties and two properties under development or redevelopment, of which 14 were wholly owned and six were owned through unconsolidated joint ventures. These properties are located primarily in New York, San Francisco, Washington, D.C., and Atlanta, contain a total of 8.9 million rentable square feet, and were approximately 97.4% leased as of December 31, 2018. As of December 31, 2018, our five highest geographic reportable segments, based on 2018 Annualized Lease Revenue, were as follows.

Election as a REIT We have elected to be taxed as a REIT under the Code, and have operated as such beginning with our taxable year ended December 31, 2003. To qualify as a REIT, we must meet certain organizational and operational requirements, including a requirement to distribute at least 90% of our adjusted taxable income, as defined in the Code, to our stockholders, computed without regard to the dividends-paid deduction and by excluding our net capital gain. As a REIT, we generally will not be subject to federal income tax on income that we distribute to our stockholders. If we fail to qualify as a REIT in any taxable year, we will then be subject to federal income taxes on our taxable income for that year and for the four years following the year during which qualification is lost, unless the Internal Revenue Service grants us relief under certain statutory provisions. Such an event could Page 35 materially affect our net income and net cash available for distribution to our stockholders. However, we believe that we are organized and operate in such a manner as to qualify for treatment as a REIT for federal income tax purposes. Columbia Property Trust TRS, LLC, Columbia KCP TRS, LLC, and Columbia Energy TRS, LLC (collectively, the "TRS Entities") are wholly owned subsidiaries of Columbia Property Trust and are organized as Delaware limited liability companies. The TRS Entities, among other things, provide tenant services that Columbia Property Trust, as a REIT, cannot otherwise provide. We have elected to treat the TRS Entities as taxable REIT subsidiaries. We may perform certain additional, noncustomary services for tenants of our buildings through the TRS Entities; however, any earnings related to such services are subject to federal and state income taxes. In addition, for us to continue to qualify as a REIT, we must limit our investments in taxable REIT subsidiaries to 20% of the value of our total assets. Deferred tax assets and liabilities are established for temporary differences between the financial reporting basis and the tax basis of assets and liabilities at the enacted rates expected to be in effect when the temporary differences reverse. No provisions for federal income taxes have been made in our accompanying consolidated financial statements, other than the provisions relating to the TRS Entities, as we made distributions in excess of taxable income for the periods presented. We are subject to certain state and local taxes related to property operations in certain locations, which have been provided for in our accompanying consolidated financial statements. Inflation We are exposed to inflation risk, as income from long-term leases is the primary source of our cash flows from operations. There are provisions in the majority of our tenant leases that are intended to protect us from, and mitigate the risk of, the impact of inflation. These provisions include rent steps, reimbursement billings for operating expense pass-through charges, real estate tax and insurance reimbursements on a per-square-foot basis, or in some cases, annual reimbursement of operating expenses above a certain per-square-foot allowance. However, due to the long-term nature of the leases, the leases may not reset frequently enough to fully cover inflation. Application of Critical Accounting Policies Our accounting policies have been established to conform with GAAP. The preparation of financial statements in conformity with GAAP requires management to use judgment in the application of accounting policies, including making estimates and assumptions. These judgments affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenue and expenses during the reporting periods. If our judgment or interpretation of the facts and circumstances relating to various transactions had been different, it is possible that different accounting policies would have been applied, thus resulting in a different presentation of the financial statements. Additionally, other companies may utilize different estimates that may impact the comparability of our results of operations to those of companies in similar businesses. Investment in Real Estate Assets We are required to make subjective assessments as to the useful lives of our depreciable assets. To determine the appropriate useful life of an asset, we consider the period of future benefit of the asset. These assessments have a direct impact on net income. The estimated useful lives of our assets by class are as follows: Buildings Building and site improvements Tenant improvements Intangible lease assets 40 years 5-25 years Shorter of economic life or lease term Lease term Evaluating the Recoverability of Real Estate Assets We continually monitor events and changes in circumstances that could indicate that the carrying amounts of the real estate and related intangible assets of both operating properties and properties under construction, may not be recoverable. When indicators of potential impairment are present that suggest that the carrying amounts of real estate assets and related intangible assets (liabilities) may not be recoverable, we assess the recoverability of these assets by determining whether the respective carrying values will be recovered through the estimated undiscounted future operating cash flows expected from the use of the assets and their eventual disposition. In the event that such expected undiscounted future cash flows do not exceed the carrying values, we adjust the carrying value of the real estate assets and related intangible assets to the estimated fair values, pursuant to the property, plant, and equipment accounting standard for the impairment or disposal of long-lived assets, and recognize an impairment loss. Estimated fair values Page 36 are calculated based on the following hierarchy of information, depending upon availability: (Level 1) recently quoted market prices; (Level 2) market prices for comparable properties; or (Level 3) the present value of future cash flows, including estimated residual value. Certain of our assets may be carried at an amount that exceeds that which could be realized in a current disposition transaction. Columbia Property Trust has determined that the carrying values of its real estate assets and related intangible assets are recoverable as of December 31, 2018. Projections of expected future operating cash flows require that we estimate future market rental income amounts subsequent to the expiration of current lease agreements, property operating expenses, the number of months it takes to re-lease the property, and the number of years the property is held for investment, among other factors. Due to the inherent subjectivity of the assumptions used to project future cash flows, estimated fair values may differ from the values that would be realized in market transactions. In the second quarter of 2018, we recognized an impairment loss of $30.8 million in connection with changing the holding period expectations for 222 East 41st Street in New York. We widely marketed this property for sale during the second quarter and, as a result, entered into an agreement to sell this property on May 25, 2018 and closed on the sale on May 29, 2018. Upon entering into the sale agreement, we reduced 222 East 41st Street's carrying value to reflect its fair value, estimated based on the net contract price of $284.6 million (Level 1), by recording an impairment loss of $30.8 million in the second quarter of 2018. Allocation of Purchase Price of Acquired Assets Upon the acquisition of real properties, we allocate the purchase price of properties to tangible assets, consisting of land and building, site improvements, and identified intangible assets and liabilities, including the value of in-place leases, based in each case on our estimate of their fair values. The fair values of the tangible assets of an acquired property (which includes land and building) are determined by valuing the property as if it were vacant, and the "as-if-vacant" value is then allocated to land and building based on our determination of the relative fair value of these assets. We determine the as-if-vacant fair value of a property using methods similar to those used by independent appraisers. Factors we consider in performing these analyses include an estimate of carrying costs during the expected lease-up periods considering current market conditions and costs to execute similar leases, including leasing commissions and other related costs. In estimating carrying costs, we include real estate taxes, insurance, and other operating expenses during the expected lease-up periods based on current market demand. Intangible Assets and Liabilities Arising From In-Place Leases Where We Are the Lessor As further described below, in-place leases where we are the lessor may have values related to direct costs associated with obtaining a new tenant that are avoided for in-place leases, opportunity costs associated with lost rentals that are avoided by acquiring an in-place lease, tenant relationships, and effective contractual rental rates that are above or below market: • Direct costs associated with obtaining a new tenant that are avoided for in-place leases, including commissions, tenant improvements, and other direct costs, are estimated based on management's consideration of current market costs to execute a similar lease. Such direct costs are included in intangible lease origination costs in the accompanying consolidated balance sheets and are amortized to expense over the remaining terms of the respective leases. • The value of opportunity costs associated with lost rentals avoided by acquiring an in-place lease is calculated based on the contractual amounts to be paid pursuant to the in-place leases over a market absorption period for a similar lease. Such opportunity costs are included in intangible lease assets in the accompanying consolidated balance sheets and are amortized to expense over the remaining terms of the respective leases. • The value of effective rental rates of in-place leases that are above or below the market rates of comparable leases is calculated based on the present value (using a discount rate that reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be received pursuant to the in-place leases and (ii) management's estimate of fair market lease rates for the corresponding in-place leases. This calculation includes significantly below- market renewal options for which exercise of the renewal option appears to be reasonably assured. These intangible assets or liabilities are measured over the actual or assumed (in the case of renewal options) remaining lease terms. The capitalized above-market and below-market lease values are recorded as intangible lease assets or liabilities and amortized as an adjustment to rental income over the remaining terms of the respective leases. Evaluating the Recoverability of Intangible Assets and Liabilities The values of intangible lease assets and liabilities are determined based on assumptions made at the time of acquisition and have defined useful lives, which correspond with the lease terms. There may be instances in which intangible lease assets and liabilities become impaired, and we are required to write off the remaining asset or liability immediately or over a shorter period of time. Lease restructurings, including lease terminations and lease extensions, may impact the value and useful life of in-place leases. In-place leases that are terminated, partially terminated, or modified will be evaluated for impairment if the original in-place Page 37 lease terms have been modified. In the event that the discounted cash flows of the original in-place lease stream do not exceed the discounted modified in-place lease stream, we adjust the carrying value of the intangible lease assets to the discounted cash flows and recognize an impairment loss. For in-place lease extensions that are executed more than one year prior to the original in- place lease expiration date, the useful life of the in-place lease will be extended over the new lease term with the exception of those in-place lease components, such as lease commissions and tenant allowances, which have been renegotiated for the extended term. Renegotiated in-place lease components, such as lease commissions and tenant allowances, will be amortized over the shorter of the useful life of the asset or the new lease term. Intangible Assets and Liabilities Arising From In-Place Leases Where We Are the Lessee In-place ground leases where we are the lessee may have positive or negative value associated with effective contractual rental rates that are above or below market at the time of acquisition or assumption. Such values are calculated based on the present value (using a discount rate that reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to the in-place lease and (ii) management's estimate of fair market lease rates for the corresponding in-place lease at the time of execution or assumption. This calculation includes significantly below market renewal options for which exercise of the renewal option appears to be reasonably assured. These intangible assets and liabilities are measured over the actual or assumed (in the case of renewal options) remaining lease terms. The capitalized above-market and below-market in- place lease values are recorded as intangible lease liabilities and assets, respectively, and are amortized as an adjustment to property operating costs over the remaining term of the respective ground leases. Revenue Recognition The majority of our revenues are derived from leases and are reflected as rental income and tenant reimbursements on the accompanying consolidated statements of operations. All of the leases on our assets are considered operating leases. Therefore, base rental income is generally recognized on a straight-line basis over the lease term, and tenant reimbursements are generally recognized in the period in which reimbursements for operating costs are billable to the tenant. Rents and tenant reimbursements collected in advance are recorded as deferred income on the accompanying consolidated balance sheets. In determining when to begin recognizing rental revenues, we consider a number of factors, including the nature of the physical improvements made in connection with the lease. When we own the improvements for accounting purposes, revenue recognition generally begins once the improvements are substantially complete and the lessee has taken possession of the improved space. When we do not own the improvements for accounting purposes (the lessee is the owner), revenue recognition generally begins once the lessee takes possession of the unimproved space; in these instances, the tenant allowance is accounted for as a lease incentive, which reduces rental revenues over the lease term. When evaluating which party (lessee or lessor) owns the improvements for accounting purposes, we consider a number of factors, including, among other things: whether the lease stipulates what the tenant allowance may be used for; whether the lessee or lessor retains legal title to the improvements; the expected economic life of the improvements relative to the lease term; and who directs the construction of the improvements. The determination of who owns the improvements for accounting purposes is subject to significant judgement and is not based on any one factor. Related-Party Transactions and Agreements During 2018, 2017, and 2016, we did not have any related party transactions, except as described in Note 4, Unconsolidated Joint Venture, of the accompanying consolidated financial statements. Commitments and Contingencies We are subject to certain commitments and contingencies with regard to certain transactions. Refer to Note 7, Commitments and Contingencies, to the accompanying consolidated financial statements for further explanation. Examples of such commitments and contingencies include: • • • • • guaranties related to the debt of unconsolidated joint ventures; obligations under operating leases; obligations under capital leases; commitments under existing lease agreements; and litigation. Subsequent Events We have evaluated subsequent events in connection with the preparation of our consolidated financial statements and notes thereto included in this report on Form 10-K and noted the following items in addition to those disclosed elsewhere in this report: Page 38 • On February 8, 2019, the board of directors declared dividends for the first quarter of 2019 in the amount of $0.20 per share, payable on March 15, 2019, to stockholders of record on March 1, 2019. • On January 4, 2019, we paid an aggregate amount of $23.3 million in dividends for the fourth quarter of 2018 to stockholders of record on December 3, 2018. ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK As a result of certain of our outstanding debt facilities, we are exposed to interest rate changes. Our interest rate risk management objectives are to limit the impact of interest rate changes on earnings and cash flow, primarily through a low to moderate level of overall borrowings. We manage our ratio of fixed- to floating-rate debt with the objective of achieving a mix that we believe is appropriate in light of anticipated changes. We closely monitor interest rates and will continue to consider the sources and terms of our borrowing facilities to determine whether we have appropriately guarded ourselves against the risk of increasing interest rates in future periods. Fluctuations in LIBOR may affect the amount of interest expense we incur on borrowings indexed to LIBOR, such as borrowings under the Revolving Credit Facility and the $300 Million Term Loan, which currently bear interest at the applicable LIBOR rate, as defined in the credit agreements, plus an applicable margin that is subject to adjustment based on our credit ratings. Additionally, we have entered into interest rate swaps and may enter into other interest rate swaps, caps, or other arrangements to mitigate our interest rate risk on a related financial instrument. We do not enter into derivative or interest rate transactions for speculative purposes; however, certain of our derivatives may not qualify for hedge accounting treatment. All of our debt was entered into for other-than-trading purposes. As of December 31, 2018 and 2017, the estimated fair value of our consolidated line of credit and notes payable and bonds was $1.3 billion and $1.7 billion, respectively. Our financial instruments, including bonds payable, consist of both fixed- and variable-rate debt. As of December 31, 2018, our debt consisted of the following, which includes our ownership share of debt at unconsolidated joint ventures, in thousands: 2019 2020 2021 2022 2023 Thereafter Total Maturing Debt: Effectively variable-rate debt Effectively fixed-rate debt $ $ — $ — $ — $ 50,233 $ — $ 482,000 $ — $ 532,233 — $ — $ 150,000 $ 165,750 $ 698,696 $ 1,014,446 Average Interest Rate: Effectively variable-rate debt Effectively fixed-rate debt —% —% —% —% 6.64% —% —% 3.07% 3.32% 5.07% —% 3.90% 3.63% 3.75% Our consolidated, variable-rate borrowings consist of the Revolving Credit Facility and the $150 Million Term Loan. However, only the Revolving Credit Facility bears interest at effectively variable rates, as the variable rate on the $150 Million Term Loan has been effectively fixed through the interest rate swap agreement described herein. Our unconsolidated borrowings consist of a fixed-rate mortgage note and a variable-rate construction note. As of December 31, 2018, our consolidated debt consisted of $482.0 million outstanding borrowings under the Revolving Credit Facility, $150.0 million outstanding on the $150 Million Term Loan, $349.0 million in 2026 Bonds Payable outstanding, and $349.7 million in 2025 Bonds Payable outstanding. As of December 31, 2018, there are no amounts outstanding on our $300 Million Term Loan. The amounts outstanding on our Revolving Credit Facility and our $300 Million Term Loan in the future will largely depend upon future acquisition and disposition activities. The weighted-average interest rate on all of our consolidated debt instruments was 3.60% as of December 31, 2018. Approximately $848.7 million of our consolidated debt outstanding as of December 31, 2018, is subject to fixed rates, either directly or when coupled with an interest rate swap agreement. As of December 31, 2018, these balances incurred interest expense at an average interest rate of 3.75% and have expirations ranging from 2022 through 2026. A change in the market interest rate impacts the net financial instrument position of our fixed-rate debt portfolio; however, it has no impact on interest incurred or cash flows. Approximately $482.0 million of our consolidated debt outstanding as of December 31, 2018, is subject to variable rates. As of December 31, 2018, this balance incurred interest expense at an interest rate of 3.32% and expires in 2023. An increase or decrease of 100 basis points would have a $4.8 million annual impact on our interest payments. The amounts outstanding on our variable- rate debt facilities in the future will largely depend upon future acquisition and disposition activity and other financing activities. Page 39 Our Market Square Joint Venture holds a $325 million mortgage note, which bears interest at a fixed rate of 5.07%; and our 799 Broadway Joint Venture holds a $101.1 million construction note, which bears interest at a floating rate of 6.64% as of December 31, 2018. Adjusting for our ownership share of the debt at these unconsolidated joint ventures, our weighted-average interest rate of all of our debt instruments is 3.85%. ITEM 8.

CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE There were no disagreements with our independent registered public accountants during 2018, 2017, or 2016. ITEM 9A. CONTROLS AND PROCEDURES Management's Conclusions Regarding the Effectiveness of Disclosure Controls and Procedures We carried out an evaluation, under the supervision and with the participation of management, including the Principal Executive Officer and Principal Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Rule 13a-15(e) under the Exchange Act as of the end of the period covered by this report. Based upon that evaluation, the Principal Executive Officer and Principal Financial Officer concluded that our disclosure controls and procedures were effective as of the end of the period covered by this report in providing a reasonable level of assurance that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods in SEC rules and forms, including providing a reasonable level of assurance that information required to be disclosed by us in such reports is accumulated and communicated to our management, including our Principal Executive Officer and our Principal Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. Report of Management on Internal Control Over Financial Reporting Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act, as a process designed by, or under the supervision of, the Principal Executive Officer and Principal Financial Officer and effected by our management and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP and includes those policies and procedures that: • • • pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and disposition of our assets; provide reasonable assurance that the transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that our receipts and expenditures are being made only in accordance with authorizations of management and/or members of the board of directors; and provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of our assets that could have a material effect on the financial statements. Because of the inherent limitations of internal control over financial reporting, including the possibility of human error and the circumvention or overriding of controls, material misstatements may not be prevented or detected on a timely basis. In addition, projections of any evaluation of effectiveness to future periods are subject to the risks that controls may become inadequate because of changes and conditions or that the degree of compliance with policies or procedures may deteriorate. Accordingly, even internal controls determined to be effective can provide only reasonable assurance that the information required to be disclosed in reports filed under the Exchange Act is recorded, processed, summarized, and represented within the time periods required. Our management has assessed the effectiveness of our internal control over financial reporting at December 31, 2018. To make this assessment, we used the criteria for effective internal control over financial reporting described in the Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this assessment, our management believes that our system of internal control over financial reporting met those criteria, and therefore our management has concluded that we maintained effective internal control over financial reporting as of December 31, 2018. The report of the Company's independent registered public accounting firm on internal control over financial reporting for the Company is included in Part IV, Item 15, of this annual report on Form 10-K and is incorporated herein by reference. Page 40 Changes in Internal Control Over Financial Reporting There have been no changes in our internal control over financial reporting during the quarter ended December 31, 2018, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. Page 41 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the shareholders and the Board of Directors of Columbia Property Trust, Inc.: Opinion on Internal Control over Financial Reporting We have audited the internal control over financial reporting of Columbia Property Trust, Inc. and subsidiaries (the "Company") as of December 31, 2018, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2018, based on criteria established in Internal Control - Integrated Framework (2013) issued by COSO. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements and financial statement schedule as of and for the year ended December 31, 2018, of the Company and our report dated February 13, 2019, expressed an unqualified opinion on those financial statements. Basis for Opinion The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Report of Management on 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 are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. Definition and Limitations of Internal Control over Financial Reporting A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. /s/ Deloitte & Touche LLP Atlanta, Georgia February 13, 2019 Page 42 ITEM 9B.

In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2018 and 2017, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2018, in conformity with accounting principles generally accepted in the United States of America. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2018, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 13, 2019, expressed an unqualified opinion on the Company's internal control over financial reporting. Basis for Opinion These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements.

("Columbia Property Trust") (NYSE: CXP) is a Maryland corporation that operates as a real estate investment trust ("REIT") for federal income tax purposes and owns and operates commercial real estate properties. Columbia Property Trust was incorporated in 2003, commenced operations in 2004, and conducts business primarily through Columbia Property Trust Operating Partnership, L.P. ("Columbia Property Trust OP"), a Delaware limited partnership. Columbia Property Trust is the general partner and sole owner of Columbia Property Trust OP and possesses full legal control and authority over its operations. Columbia Property Trust OP acquires, develops, redevelops, owns, leases, and operates real properties directly, through wholly owned subsidiaries, or through unconsolidated joint ventures. Unless otherwise noted, references to Columbia Property Trust, "we," "us," or "our" herein shall include Columbia Property Trust and all subsidiaries of Columbia Property Trust, direct and indirect. Columbia Property Trust typically acquires, develops, or redevelops high-quality, income-generating office properties. As of December 31, 2018, Columbia Property Trust owned 18 operating properties and two properties under development or redevelopment, of which 14 were wholly owned and six were owned through unconsolidated joint ventures. These properties are located primarily in New York, San Francisco, Washington, D.C., and Atlanta, contain a total of 8.9 million rentable square feet, and were approximately 97.4% leased as of December 31, 2018. 2. Summary of Significant Accounting Policies Basis of Presentation The consolidated financial statements of Columbia Property Trust have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") and include the accounts of Columbia Property Trust, Columbia Property Trust OP, and any variable interest entity ("VIE") in which Columbia Property Trust or Columbia Property Trust OP is deemed the primary beneficiary. With respect to entities that are not VIEs, Columbia Property Trust's consolidated financial statements shall also include the accounts of any entity in which Columbia Property Trust, Columbia Property Trust OP, or its subsidiaries own a controlling financial interest and any limited partnership in which Columbia Property Trust, Columbia Property Trust OP, or its subsidiaries own a controlling general partnership interest. In determining whether Columbia Property Trust or Columbia Property Trust OP has a controlling interest, the following factors are considered, among other things: the ownership of voting interests, protective rights, and participatory rights of the investors. All intercompany balances and transactions have been eliminated in consolidation. Use of Estimates The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the accompanying consolidated financial statements and the accompanying notes. Actual results could differ from those estimates. Fair Value Measurements Columbia Property Trust estimates the fair value of its assets and liabilities (where currently required under GAAP) consistent with the provisions of Accounting Standard Codification 820, Fair Value Measurements ("ASC 820"). Under this standard, fair value is defined as the price that would be received upon sale of an asset or paid upon transfer of a liability in an orderly transaction between market participants at the measurement date. While various techniques and assumptions can be used to estimate fair value depending on the nature of the asset or liability, the accounting standard for fair value measurements and disclosures provides the following fair value technique parameters and hierarchy, depending upon availability: Level 1 – Assets or liabilities for which the identical term is traded on an active exchange, such as publicly traded instruments or futures contracts. Level 2 – Assets and liabilities valued based on observable market data for similar instruments. Level 3 – Assets or liabilities for which significant valuation assumptions are not readily observable in the market. Such assets or liabilities are valued based on the best available data, some of which may be internally developed. Significant assumptions may include risk premiums that a market participant would consider. F-8 Real Estate Assets Real estate assets are stated at cost, less accumulated depreciation and amortization. Amounts capitalized to real estate assets consist of the cost of acquisition or construction, and any tenant improvements or major improvements that extend the useful life of the related asset. All repairs and maintenance are expensed as incurred. As further described in Note 5, Line of Credit and Notes Payable, Columbia Property Trust capitalizes interest incurred on outstanding debt balances as well as joint venture investments, as appropriate, during development or redevelopment of real estate held directly or in unconsolidated joint ventures. During 2018, $3.8 million of interest was capitalized to construction in progress, and $0.2 million was capitalized to investments in unconsolidated joint ventures. During 2017, $0.7 million of interest was capitalized to construction in progress. Columbia Property Trust is required to make subjective assessments as to the useful lives of its depreciable assets. To determine the appropriate useful life of an asset, Columbia Property Trust considers the period of future benefit of the asset. These assessments have a direct impact on net income. The estimated useful lives of its assets by class are as follows: Buildings Building and site improvements 40 years 5-25 years Tenant improvements Intangible lease assets Assets Held for Sale Shorter of economic life or lease term Lease term Columbia Property Trust classifies properties as held for sale according to Accounting Standard Codification 360, Accounting for the Impairment or Disposal of Long-Lived Assets ("ASC 360"). According to ASC 360, properties, having separately identifiable operations and cash flows, are considered held for sale when the following criteria are met: • Management, having the authority to approve the action, commits to a plan to sell the property. • The property is available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such property. • An active program to locate a buyer and other actions required to complete the plan to sell the property have been initiated. • The property is being actively marketed for sale at a price that is reasonable in relation to its current fair value. • Actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. • The sale of the property is probable (i.e., typically subject to a binding sale contract with a non-refundable deposit), and transfer of the property is expected to qualify for recognition as a completed sale, within one year. At such time that a property is determined to be held for sale, its carrying amount is adjusted to the lower of its depreciated book value or its estimated fair value, less costs to sell, and depreciation is no longer recognized; and assets and liabilities are required to be classified as held for sale on the accompanying consolidated balance sheet. As of December 31, 2018 and 2017, none of Columbia Property Trust's properties met the criteria to be classified as held for sale in the accompanying consolidated balance sheet. Evaluating the Recoverability of Real Estate Assets Columbia Property Trust continually monitors events and changes in circumstances that could indicate that the net carrying amounts of its real estate and related intangible assets and liabilities, of both operating properties and properties under redevelopment, may not be recoverable. When indicators of potential impairment are present that suggest that the net carrying amounts of real estate assets and related intangible assets and liabilities may not be recoverable, Columbia Property Trust assesses the recoverability of these net assets by determining whether the respective carrying values will be recovered through the estimated undiscounted future cash flows expected from the use of the net assets and their eventual disposition. In the event that such expected undiscounted future cash flows do not exceed the carrying values, Columbia Property Trust adjusts the carrying values of the real estate assets and related intangible assets and liabilities to the estimated fair values, pursuant to the property, plant, and equipment accounting standard for the impairment or disposal of long-lived assets, and recognizes an impairment loss. At such time that a property is required to be classified as held for sale, its net carrying amount is adjusted to the lower of its depreciated book value or its estimated fair value, less costs to sell, and depreciation is no longer recognized. Estimated fair values are calculated based on the following hierarchy of information: (i) recently quoted market prices, (ii) market prices for comparable properties, or (iii) the present value of future cash flows, including estimated residual value. Projections of F-9 expected future operating cash flows require that Columbia Property Trust estimate future market rental income amounts subsequent to the expiration of current lease agreements, property operating expenses, the number of months it takes to re-lease the property, and the number of years the property is held for investment, among other factors. Due to the inherent subjectivity of the assumptions used to project future cash flows, estimated fair values may differ from the values that would be realized in market transactions. Certain of Columbia Property Trust's assets may be carried at an amount that exceeds that which could be realized in a current disposition transaction. Columbia Property Trust has determined that the carrying values of its real estate assets and related intangible assets are recoverable as of December 31, 2018. In the second quarter of 2018, Columbia Property Trust recognized an impairment loss of $30.8 million in connection with changing the holding period expectations for 222 East 41st Street in New York. Columbia Property Trust widely marketed this property for sale during the second quarter and, as a result, entered into an agreement to sell this property on May 25, 2018 and closed on the sale on May 29, 2018. Upon entering into the sale agreement, Columbia Property Trust reduced 222 East 41st Street's carrying value to reflect its fair value, estimated based on the net contract price of $284.6 million (Level 1), by recording an impairment loss of $30.8 million in the second quarter of 2018. Allocation of Purchase Price of Acquired Assets Upon the acquisition of real properties, Columbia Property Trust allocates the purchase price of properties and related transaction costs to tangible assets, consisting of land, building, site improvements, and identified intangible assets and liabilities, including the value of in-place leases, based in each case on Columbia Property Trust's estimate of their fair values in accordance with ASC 820 (see "Fair Value Measurements" section above for additional details). In conjunction with certain acquisitions, Columbia Property Trust has entered into master lease agreements, which obligate the seller to pay rent pertaining to certain nonrevenue- producing spaces to mitigate the negative effects of lower rental revenues. Columbia Property Trust records payments receivable under such master lease agreements as a reduction of the property basis rather than income. Columbia Property Trust received no proceeds for master leases during 2018, 2017, or 2016. The fair values of the tangible assets of an acquired property (which includes land, building, and site improvements) are determined by valuing the property as if it were vacant, and the "as-if-vacant" value is then allocated to land, building, and site improvements based on management's determination of the relative fair value of these assets. Management determines the as-if-vacant fair value of a property using methods similar to those used by independent appraisers. Factors considered by management in performing these analyses include an estimate of carrying costs during the expected lease-up periods considering current market conditions and costs to execute similar leases, including leasing commissions and other related costs. In estimating carrying costs, management includes real estate taxes, insurance, and other operating expenses during the expected lease-up periods based on current market demand. Intangible Assets and Liabilities Arising From In-Place Leases Where Columbia Property Trust Is the Lessor As further described below, in-place leases with Columbia Property Trust as the lessor may have values related to: direct costs associated with obtaining a new tenant that are avoided for in-place leases, opportunity costs associated with lost rentals that are avoided by acquiring an in-place lease, tenant relationships, and effective contractual rental rates that are above or below market: • Direct costs associated with obtaining a new tenant that are avoided for in-place leases, including commissions, tenant improvements, and other direct costs, are estimated based on management's consideration of current market costs to execute a similar lease. Such direct costs are included in intangible lease origination costs in the accompanying consolidated balance sheets and are amortized to expense over the remaining terms of the respective leases. • The value of opportunity costs associated with lost rentals avoided by acquiring an in-place lease is calculated based on contractual amounts to be paid pursuant to the in-place leases over a market absorption period for a similar lease. Such opportunity costs ("Absorption Period Costs") are included in intangible lease assets in the accompanying consolidated balance sheets and are amortized to expense over the remaining terms of the respective leases. • The value of effective rental rates of in-place leases that are above or below the market rates of comparable leases is calculated based on the present value (using a discount rate that reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be received pursuant to the in-place leases and (ii) management's estimate of fair market lease rates for the corresponding in-place leases. This calculation includes significantly below- market renewal options for which exercise of the renewal option appears to be reasonably assured. These intangible assets or liabilities are measured over the actual or assumed (in the case of renewal options) remaining lease terms. The capitalized above-market and below-market lease values are recorded as intangible lease assets or liabilities and amortized as an adjustment to rental income over the remaining terms of the respective leases.

Such values are calculated based on the present value (using a discount rate that reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to the in-place lease and (ii) management's estimate of fair market lease rates for the corresponding in-place lease at the time of execution or assumption. This calculation includes significantly below-market renewal options for which exercise of the renewal option appears to be reasonably assured. These intangible assets and liabilities are measured over the actual or assumed (in the case of renewal options) remaining lease terms. The capitalized above-market and below-market in-place lease values are recorded as intangible lease liabilities and assets, respectively, and are amortized as an adjustment to property operating costs over the remaining term of the respective leases. Columbia Property Trust had gross below- market lease assets of approximately $32.6 million and $140.9 million as of December 31, 2018 and 2017, respectively, net of accumulated amortization of $2.6 million and $22.8 million as of December 31, 2018 and 2017, respectively. Columbia Property F-11 Trust recognized amortization expense related to these assets of approximately $1.4 million for 2018 and $2.5 million for both 2017 and 2016. As of December 31, 2018, the remaining net below-market lease asset will be amortized as follows (in thousands): For the Years Ending December 31: 2019 2020 2021 2022 2023 Thereafter Weighted-average amortization period Cash and Cash Equivalents $ $ 555 555 555 555 555 27,203 29,978 58 years Columbia Property Trust considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Cash equivalents may include cash and short-term investments. Short-term investments are stated at cost, which approximates fair value as of December 31, 2018 and 2017. Tenant Receivables, Net Tenant receivables consist of rental and reimbursement billings due from tenants. Tenant receivables are recorded at the original amount earned, less an allowance for any doubtful accounts, which approximates fair value. Management assesses the realizability of tenant receivables on an ongoing basis and provides for allowances as such balances, or portions thereof, become uncollectible. Columbia Property Trust adjusted the allowance for doubtful accounts by recording a provision for doubtful accounts, net of recoveries, in general and administrative expenses in the accompanying consolidated statements of operations of approximately $63,000 and $26,000 for 2018 and 2017, respectively. Straight-Line Rent Receivable Straight-line rent receivable reflects the amount of cumulative adjustments necessary to present rental income on a straight-line basis. Columbia Property Trust recognizes rental revenues on a straight-line basis, ratably over the term of each lease; however, leases often provide for payment terms that differ from the revenue recognized. When the amount of cash billed is less than the amount of revenue recognized, typically early in the lease, straight-line rent receivable is recorded for the difference. The receivable is depleted during periods later in the lease when the amount of cash paid by the tenant is greater than the amount of revenue recognized. Prepaid Expenses and Other Assets Prepaid expenses and other assets primarily include earnest money deposits, escrow accounts held by lenders to pay future real estate taxes, insurance and tenant improvements, notes receivable, nontenant receivables, prepaid taxes, insurance and operating costs, unamortized deferred financing costs related to the line of credit (the "Revolving Credit Facility"), interest rate swaps (when in an asset position), certain corporate assets, hotel inventory, and deferred tax assets. Prepaid expenses are recognized over the period to which the good or service relates. Other assets are written off when the asset no longer has future value, or when the company is no longer obligated for the corresponding liability. Deferred Financing Costs Deferred financing costs include costs incurred to secure debt from third-party lenders. Deferred financing costs, except for costs related to the Revolving Credit Facility, are presented as a direct reduction to the carrying amount of the related debt for all periods presented. Deferred financing costs related to the Revolving Credit Facility are included in prepaid expenses and other assets. Columbia Property Trust recognized amortization of deferred financing costs for the years ended December 31, 2018, 2017, and 2016 of approximately $2.9 million, $2.8 million, and $3.3 million, respectively, which is included in interest expense in the accompanying consolidated statements of operations. F-12 Deferred Lease Costs Deferred lease costs include costs incurred to procure leases that are paid to third parties or tenants, and incentives that are provided to tenants under the terms of their leases. These costs are capitalized and amortized on a straight-line basis over the terms of the lease. Amortization of third-party leasing costs is reflected as amortization expense, and amortization of lease incentives is reflected as an adjustment to rental income. During 2018, 2017, and 2016, Columbia Property Trust recognized amortization expense for deferred lease costs of $5.5 million, $5.2 million, and $9.3 million, respectively. During 2018, 2017, and 2016, Columbia Property Trust recognized adjustments to rental income for amortization of deferred lease costs of $2.1 million, $3.3 million, and $3.9 million, respectively. Upon receiving notification of a tenant's intention to terminate a lease, unamortized deferred lease costs are amortized over the shortened lease period. As of December 31, 2017, deferred lease costs included $68.4 million in unamortized lease incentives for a lease at the 222 East 41st Street Property, which was sold in May 2018. Investments in Development Authority Bonds and Obligations Under Capital Leases In connection with the acquisition of certain real estate assets, Columbia Property Trust has assumed investments in development authority bonds and corresponding obligations under capital leases of land or buildings. The county development authority issued bonds to developers to finance the initial development of these projects, a portion of which was then leased back to the developer under a capital lease. This structure enabled the developer to receive property tax abatements over the concurrent terms of the development authority bonds and capital leases. The remaining property tax abatement benefits transferred to Columbia Property Trust upon assumption of the bonds and corresponding capital leases at acquisition. The development authority bonds and the obligations under the capital leases are both recorded at their net present values, which Columbia Property Trust believes approximates fair value. The related amounts of interest income and expense are recognized as earned in equal amounts and, accordingly, do not impact net income. In December 2018, Columbia Property Trust terminated both the $120.0 million development authority bonds and the corresponding obligations under capital leases related to One & Three Glenlake Parkway in Atlanta. Accounts Payable, Accrued Expenses, and Accrued Capital Expenditures Accounts payable, accrued expenses, and accrued capital expenditures primarily include payables related to property operations, capital projects, and interest rate swaps (when in a liability position). As of December 31, 2017, accounts payable, accrued expenses, and accrued capital expenditures includes approximately $54.7 million in lease incentives related to a lease at the 222 East 41st Street Property, which was sold in May 2018. Line of Credit and Notes Payable When debt is assumed, Columbia Property Trust records the loan at fair value. The fair value adjustment is amortized to interest expense over the term of the loan using the effective interest method. As described in the "Deferred Financing Costs" section above, line of credit and notes payable is presented on the accompanying consolidated balance sheet net of deferred financing costs related to term loans and notes payable of $2.7 million and $3.0 million as of December 31, 2018 and December 31, 2017, respectively. Bonds Payable In August 2016, Columbia Property Trust issued $350 million of its 10-year unsecured 3.650% senior notes at 99.626% of their face value (the "2026 Bonds Payable"). In March 2015, Columbia Property Trust issued $350.0 million of its 10-year unsecured 4.150% senior notes at 99.859% of their face value (the "2025 Bonds Payable"). The discount on the 2026 Bonds Payable and the 2025 Bonds Payable is amortized to interest expense over the term of the bonds using the effective-interest method. As described in the "Deferred Financing Costs" section above, bonds payable are presented on the accompanying consolidated balance sheet net of deferred financing costs related to bonds payable of $4.2 million and $4.8 million as of December 31, 2018 and December 31, 2017, respectively. F-13 Common Stock Repurchase Program Columbia Property Trust's board of directors has authorized repurchases of its common stock, par value $0.01 per share, subject to certain limitations, as described in Note 8, Equity. Columbia Property Trust expects to acquire shares primarily through open market transactions, subject to market conditions and other factors. As of December 31, 2018, $124.4 million remains available for repurchases under the current stock repurchase program. Common stock repurchases are charged against equity as incurred, and the repurchased shares are retired. See Note 8, Equity, for additional details. Preferred Stock Columbia Property Trust is authorized to issue up to 100.0 million shares of one or more classes or series of preferred stock with a par value of $0.01 per share. Columbia Property Trust's board of directors may determine the relative rights, preferences, and privileges of each class or series of preferred stock issued, which may be more beneficial than the rights, preferences, and privileges attributable to Columbia Property Trust's common stock. To date, Columbia Property Trust has not issued any shares of preferred stock. Common Stock The par value of Columbia Property Trust's issued and outstanding shares of common stock is classified as common stock, with the remainder allocated to additional paid-in capital. Distributions To maintain its status as a REIT, Columbia Property Trust is required by the Internal Revenue Code of 1986, as amended (the "Code"), to make distributions to stockholders each taxable year equal to at least 90% of its REIT taxable income, computed without regard to the dividends-paid deduction and by excluding net capital gains attributable to stockholders ("REIT taxable income"). To the extent that Columbia Property Trust satisfies the distribution requirement but distributes less than 100% of its REIT taxable income, Columbia Property Trust would be subject to federal and state corporate income tax on the undistributed income. Distributions to the stockholders are determined by the board of directors of Columbia Property Trust and are dependent upon a number of factors relating to Columbia Property Trust, including funds available for payment of distributions, financial condition, the timing of property acquisitions, capital expenditure requirements, and annual distribution requirements in order to maintain Columbia Property Trust's status as a REIT under the Code. Interest Rate Swap Agreements Columbia Property Trust enters into interest rate swap contracts to mitigate its interest rate risk on the related financial instruments. Columbia Property Trust does not enter into derivative or interest rate transactions for speculative purposes; however, certain of its derivatives may not qualify for hedge accounting treatment. Columbia Property Trust records the fair value of its interest rate swaps on its consolidated balance sheet either as prepaid expenses and other assets or as accounts payable, accrued expenses, and accrued capital expenditures. Changes in the fair value of interest rate swaps that are designated as cash flow hedges are recorded as other comprehensive income. Changes in the fair value of interest rate swaps that do not qualify for hedge accounting treatment are recorded as gain or loss on interest rate swaps. Amounts received or paid under interest rate swap agreements are recorded as interest expense for contracts that qualify for hedge accounting treatment and as loss on interest rate swaps for contracts that do not qualify for hedge accounting treatment. The following tables provide additional information related to Columbia Property Trust's interest rate swaps as of December 31, 2018 and 2017 (in thousands): Instrument Type Derivatives Designated as Hedging Instruments: Balance Sheet Classification 2018 2017 Estimated Fair Value as of December 31, Interest rate contract Prepaid expenses and other assets $ 2,344 $ 903 As a result of the interest rate contract in the above table, Columbia Property Trust estimates recognizing a reduction in interest expense of approximately $0.9 million over the next 12 months. F-14 Columbia Property Trust applied the provisions of ASC 820 in recording its interest rate swaps at fair value. The fair values of the interest rate swaps, classified under Level 2, were determined using a third-party proprietary model that is based on prevailing market data for contracts with matching durations, current and anticipated London Interbank Offered Rate ("LIBOR") information, and reasonable estimates about relevant future market conditions. Columbia Property Trust has determined that the fair value, as determined by the third party, is reasonable. Years Ended December 31, 2018 2017 2016 Market value adjustment to interest rate swaps designated as hedging instruments and included in other comprehensive income $ 1,441 $ 1,786 $ 1,553 Revenue Recognition The majority of Columbia Property Trust’s revenues are derived from leases and are reflected as rental income and tenant reimbursements on the accompanying consolidated statements of operations. All of the leases on Columbia Property Trust's assets are considered operating leases. Therefore, base rental income is generally recognized on a straight-line basis over the lease term, and tenant reimbursements are generally recognized in the period in which reimbursements for operating costs are billable to the tenant. Rents and tenant reimbursements collected in advance are recorded as deferred income on the accompanying consolidated balance sheets. In determining when to begin recognizing rental revenues, Columbia Property Trust considers a number of factors, including the nature of the physical improvements made in connection with the lease. When Columbia Property Trust owns the improvements for accounting purposes, revenue recognition generally begins once the improvements are substantially complete and the lessee has taken possession of the improved space. When Columbia Property Trust does not own the improvements for accounting purposes (the lessee is the owner), revenue recognition generally begins once the lessee takes possession of the unimproved space; in these instances, the tenant allowance is accounted for as a lease incentive, which reduces rental revenues over the lease term. When evaluating which party (lessee or lessor) owns the improvements for accounting purposes, Columbia Property Trust considers a number of factors, including, among other things: whether the lease stipulates what the tenant allowance may be used for; whether the lessee or lessor retains legal title to the improvements; the expected economic life of the improvements relative to the lease term; and who directs the construction of the improvements. The determination of who owns the improvements for accounting purposes is subject to significant judgement and is not based on any one factor. Lease termination fees are recognized on a straight-line basis from the point at which Columbia Property Trust receives notification of termination until the date the tenant loses the right to lease the space and Columbia Property Trust has satisfied all obligations under the lease or termination agreement. During 2018, 2017, and 2016, Columbia Property Trust earned lease termination revenues of $2.2 million, $0.4 million, and $11.4 million, respectively, which are included in other property income on the accompanying consolidated statements of operations. For information about Columbia Property Trust’s other revenue streams, please see Note 14, Non-Lease Revenues. Income Taxes Columbia Property Trust has elected to be taxed as a REIT under the Code, and has operated as such beginning with its taxable year ended December 31, 2003. To qualify as a REIT, Columbia Property Trust must meet certain organizational and operational requirements, including a requirement to distribute at least 90% of its REIT taxable income, as defined by the Code, to its stockholders. As a REIT, Columbia Property Trust generally is not subject to income tax on income it distributes to stockholders. Columbia Property Trust's stockholder distributions typically exceed its taxable income due to the inclusion of noncash expenses, such as depreciation, in taxable income. As a result, Columbia Property Trust typically does not incur federal income taxes other than as described in the following paragraph. Columbia Property Trust is, however, subject to certain state and local taxes related to the operations of properties in certain locations, which have been provided for in the accompanying consolidated financial statements. Columbia Property Trust TRS, LLC, Columbia KCP TRS, LLC, and Columbia Energy TRS, LLC (collectively, the "TRS Entities") are wholly owned subsidiaries of Columbia Property Trust and are organized as Delaware limited liability companies. The TRS Entities, among other things, provide tenant services that Columbia Property Trust, as a REIT, cannot otherwise provide. Columbia Property Trust has elected to treat the TRS Entities as taxable REIT subsidiaries. Columbia Property Trust may perform certain additional, noncustomary services for tenants of its buildings through the TRS Entities; however, any earnings related to such services are subject to federal and state income taxes. In addition, for Columbia Property Trust to continue to qualify as a REIT, Columbia Property Trust must limit its investments in taxable REIT subsidiaries to 20% of the value of the total assets. The TRS F-15 Entities' deferred tax assets and liabilities represent temporary differences between the financial reporting basis and the tax basis of assets and liabilities based on the enacted rates expected to be in effect when the temporary differences reverse. If applicable, Columbia Property Trust records interest and penalties related to uncertain tax positions as general and administrative expense in the accompanying consolidated statements of operations. Segment Information As of December 31, 2018, Columbia Property Trust's reportable segments are determined based on the geographic markets in which it has significant investments. Columbia Property Trust considers geographic location when evaluating its portfolio composition, and in assessing the ongoing operations and performance of its properties (see Note 15, Segment Information). Reclassification Certain prior-period amounts may be reclassified to conform to the current-period financial statement presentation. Within revenues on the consolidated statements of operations, rental income and tenant reimbursements have been combined into the line item Rental income and tenant reimbursements for all periods presented. Recent Accounting Pronouncements In October 2018, the FASB issued Accounting Standard Update 2018-13, Fair Value Measurement: Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement ("ASU 2018-13"), which expands the disclosure requirements related to a change in fair value technique hierarchy. ASU 2018-13 will be effective for Columbia Property Trust on January 1, 2020, and is not expected to have a material impact on Columbia Property Trust's financial statements or disclosures. In February 2017, the FASB issued Accounting Standard Update 2017-05, Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Non-Financial Assets ("ASU 2017-05"), which applies to the partial sale of non-financial assets, including real estate assets, to unconsolidated joint ventures. ASU 2017-05 requires Columbia Property Trust to measure its residual joint venture interest in properties transferred to unconsolidated joint ventures at fair value as of the transaction date by recognizing a gain or loss on 100% of the asset transferred (i.e., to fully step-up the basis of the residual investment in the joint venture). Columbia Property Trust adopted the new rule effective January 1, 2018 on a modified retrospective basis by recording a cumulative-effect adjustment to equity equal to the total gain on residual joint venture interests as of the transaction dates for the partial sales of Market Square, 333 Market Street, and University Circle, adjusted to reflect the impact of depreciating the additional step-ups through January 1, 2018. The adoption of this standard resulted in an increase to investments in unconsolidated joint ventures and equity of $357.8 million. In February 2016, the FASB issued Accounting Standards Update 2016-02, Leases ("ASU 2016-02"), which amends the existing standards for lease accounting by requiring lessees to recognize most leases on their balance sheets and by making targeted changes to lessor accounting and reporting. Columbia Property Trust adopted ASU 2016-02 effective January 1, 2019, with the following key lessee and lessor accounting changes: • The new standard requires lessees to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months, and classify such leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase of the leased asset by the lessee, or not. This classification will determine whether the lease expense is recognized based on an effective interest method (finance leases) or on a straight-line basis over the term of the lease (operating leases). Leases with a term of 12 months or less will be accounted for using an approach that is similar to existing guidance for operating leases today. Upon adoption ASU 2016-02, Columbia Property Trust anticipates recording a $32.0 million lease liability for its ground leases. • The new standard requires lessors to account for leases using an approach that is substantially equivalent to existing guidance as applies to sales-type leases, direct-financing leases, and operating leases; however, under ASU 2016-02, lessors are only permitted to capitalize and amortize initial direct costs associated with obtaining a lease. In July 2018, the FASB issued ASU 2018-11 Targeted Improvements Leasing, ("ASU 2018-11"), which provides "practical expedient" options (a) to implement ASU 2016-02 prospectively by only applying the new rules to leases that are in place as of the effective date on a go-forward basis, and (b) for lessors to combine revenues from lease and non-lease components. Columbia Property Trust anticipates using both of the practical expedients. In May 2014, the FASB issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers ("ASU 2014-09"), which establishes a comprehensive model to account for revenues arising from contracts with customers. ASU 2014-09 applies to all contracts with customers, except those that are within the scope of other topics in the FASB's Accounting Standards Codification, such as real estate leases. ASU 2014-09 requires companies to perform a five-step analysis of transactions to determine when and how revenue is recognized. For Columbia Property Trust, the new standard applies primarily to fees earned from managing F-16 properties owned by its unconsolidated joint ventures and parking agreements with tenants. Given the structure of these agreements, the adoption of ASU 2014-09 has not materially impacted the timing or amount of Columbia Property Trust's revenues; however, Columbia Property Trust has included more extensive disclosures about its revenue streams and contracts with customers, which are presented in Note 14, Non-Lease Revenues. ASU 2014-09 was effective for Columbia Property Trust on January 1, 2018. Columbia Property Trust has applied the modified retrospective approach of adoption, which resulted in the recognition of a cumulative effect adjustment to equity of $0.3 million, with no retrospective adjustments to prior periods. 3.

Columbia Property Trust acquired 149 Madison Avenue subject to a ground lease which expired in January 2018. Columbia Property Trust is redeveloping this property. For the period from November 28, 2017 to December 31, 2017, Columbia Property Trust recognized $10,300 of revenues and net income of $9,200 from 149 Madison Avenue. F-17 1800 M Street Joint Venture Columbia Property Trust entered a new joint venture partnership with Allianz Real Estate of America LLC ("Allianz"), which simultaneously acquired 1800 M Street, a 10-story, 581,000-square-foot office building in Washington, D.C. that is 94% leased, for a total of $421.0 million (the "1800 M Street Joint Venture"). Columbia Property Trust owns a 55% interest in the 1800 M Street Joint Venture, and Allianz owns the remaining 45%. 249 West 17th Street & 218 West 18th Street 249 West 17th Street is made up of two interconnected 12- and six-story towers, totaling 281,000 square feet of office and retail space, and 218 West 18th Street is a 12-story, 166,000-square-foot office building.

Columbia Property Trust recognized an impairment loss of $30.8 million related to this property in the second quarter of 2018, as further described in Note 2, Summary of Significant Accounting Policies. The proceeds from this transaction were used to fully repay the $180.0 million remaining balance on the $300 Million Bridge Loan, as described in Note 5, Line of Credit and Notes Payable. 263 Shuman Boulevard On April 13, 2018, Columbia Property Trust transferred 263 Shuman Boulevard to the lender in extinguishment of the loan principal of $49.0 million, accrued interest expense, and accrued property operating costs, which resulted in a gain on extinguishment of debt of $24.0 million in the second quarter of 2018. F-19 University Circle & 333 Market Street On July 6, 2017, Columbia Property Trust contributed 333 Market Street and the University Circle to joint ventures, and simultaneously sold a 22.5% interest in those joint ventures for $234.0 million to Allianz, an unrelated third party (collectively, the "San Francisco Joint Ventures"). On February 1, 2018, as agreed at the time of the initial San Francisco Joint Ventures formation, Allianz acquired another 22.5% interest in each of the San Francisco Joint Ventures at an aggregate price of $235.3 million, thereby reducing Columbia Property Trust's equity interest in each joint venture to 55.0%. These proceeds were used to reduce the balance on the $300 Million Bridge Loan and the Revolving Credit Facility, as described in Note 5, Line of Credit and Notes Payable. Key Center Tower & Marriott Key Center Tower & Marriott were sold in one transaction for $254.5 million of gross proceeds and a $13.0 million, 10-year accruing note receivable from the principal of the buyer. As a result, Columbia Property Trust has applied the installment method to account for this transaction, and deferred $13.0 million of the total $22.5 million gain on sale. The Key Center Tower and Key Center Marriott generated net income of $14.5 million for the year ended December 31, 2016; and a net loss of $1.9 million for the first 31 days of 2017, excluding the gain on sale. Houston Property Sale 5 Houston Center, Energy Center I, and 515 Post Oak were sold in one transaction. These properties generated net income of $11.1 million for the year ended December 31, 2016; and a net loss of $14.9 thousand for the first six days of 2017, excluding the gain on sale. 100 East Pratt The net sale proceeds of $159.4 million from 100 East Pratt were used to repay the $119.0 million remaining on a bridge loan on April 1, 2016. 4. Unconsolidated Joint Ventures As of December 31, 2018 and December 31, 2017, Columbia Property Trust owns interests in the following properties through joint ventures, which are accounted for using the equity method of accounting: Joint Venture(2) Property Name Geographic Market Ownership Interest December 31, 2018 December 31, 2017 Carrying Value of Investment(1) Market Square Joint Venture Market Square Washington, D.C.

Columbia Property Trust adopted ASU 2017-05 effective January 1, 2018, requiring Columbia Property Trust to measure its residual joint venture interest in the properties transferred to unconsolidated joint ventures at fair value as of the transaction date (i.e., to fully step-up the basis of the residual investment in the joint venture). The new rule was adopted on a modified retrospective basis by recording a cumulative-effect adjustment to equity equal to the original gain or loss as of the respective transaction dates, adjusted to reflect the impact of amortizing the additional step-ups through January 1, 2018. The adoption of this standard resulted in an increase to investments in unconsolidated joint ventures and equity by $357.8 million on January 1, 2018, for the previous partial sales of interest in the Market Square, 333 Market Street, and University Circle properties. (2) See the "Dispositions" section of Note 3, Real Estate Transactions, for a description of the formation of these joint ventures. (3) On February 1, 2018, Allianz acquired from Columbia Property Trust an additional 22.5% interest in each of the University Circle Joint Venture and the 333 Market Street Joint Venture, thereby reducing Columbia Property Trust's equity interest in each joint venture to 55.0%. (4) Columbia Property Trust capitalized interest of $0.2 million on its investment in the 799 Broadway Joint Venture in 2018. F-20 Columbia Property Trust has determined that none of its unconsolidated joint ventures are variable interest entities. However, Columbia Property Trust and its partners have substantive participation rights in the joint ventures, including management selection and termination, and the approval of operating and capital decisions. As such, Columbia Property Trust uses the equity method of accounting to record its investment in these joint ventures. Under the equity method, the investment in the joint ventures is recorded at cost and adjusted for cash contributions and distributions, and allocations of income or loss. Columbia Property Trust evaluates the recoverability of its investments in unconsolidated joint ventures in accordance with accounting standards for equity investments by first reviewing the investment for any indicators of impairment. If indicators are present, Columbia Property Trust estimates the fair value of the investment. If the carrying value of the investment is greater than the estimated fair value, management makes an assessment of whether the impairment is "other-than-temporary." In making this assessment, management considers the following: (1) the length of time and the extent to which fair value has been less than cost, and (2) Columbia Property Trust's intent and ability to retain its interest long enough for a recovery in market value. Based on the assessment as described above, Columbia Property Trust has determined that none of its investments in joint ventures are other- than-temporarily impaired as of December 31, 2018. Joint Venture Debt and Related Guarantees Two joint ventures have outstanding debt, of which Columbia Property Trust guarantees a portion of each note: • The Market Square Joint Venture has a mortgage note with an outstanding balance of $325.0 million as of December 31, 2018 and December 31, 2017. The Market Square mortgage note bears interest at 5.07% and matures on July 1, 2023. Columbia Property Trust guarantees a portion of the Market Square mortgage note, the amount of which has been reduced to $5.8 million as of December 31, 2018 from $11.2 million as of December 31, 2017, as a result of leasing at the property. The amount of the guaranty will continue to be reduced as space is leased. • At inception, the 799 Broadway Joint Venture borrowed $97.0 million under a construction loan with total capacity of $187.0 million (the "Construction Loan"). As of December 31, 2018, $101.1 million is outstanding on the Construction Loan. Borrowings under the Construction Loan bear interest at LIBOR, as defined in the loan agreement, which is capped at 4.00%, plus a spread of 4.25%. A portion of the monthly interest payment accrues into the balance of the loan. The Construction Loan matures on October 9, 2021, with two, one-year extension options. Pursuant to a joint and several guaranty agreement with the construction loan lender, Columbia Property Trust and Normandy are required to make aggregate additional equity contributions to the joint venture based on the initial expected project costs, less the amount of equity contributions made to date. As of December 31, 2018, Columbia Property Trust and Normandy are required to make aggregate additional equity contributions of $50.9 million, of which $25.3 million reflects Columbia Property Trust's allocated share. Equity contributions become payable to the joint venture when a capital call is received.

There is an aggregate net difference of $282.0 million and $32.0 million as of December 31, 2018 and 2017, respectively, between the historical costs recorded at the joint venture level, and Columbia Property Trust's investments in unconsolidated joint ventures. Such basis differences result from the basis adjustments recorded pursuant to ASU 2017-05, as described in Note 2, Summary of Significant Accounting Policies; differences in the timing of each partner's joint venture interest acquisition; and formation costs incurred by Columbia Property Trust. Basis differences are amortized to income (loss) from unconsolidated joint ventures over the lives of the underlying assets or liabilities.

Asset and Property Management Fee Income Columbia Property Trust provides property and asset management services to the Market Square Joint Venture, the University Circle Joint Venture, the 333 Market Street Joint Venture, and the 1800 M Street Joint Venture. Under these agreements, Columbia Property Trust oversees the day-to-day operations of these joint ventures and their properties, including property management, property accounting, and other administrative services. During the years ended December 31, 2018, 2017, and 2016, Columbia Property Trust earned the following fees from these unconsolidated joint ventures (in thousands): Market Square Joint Venture University Circle Joint Venture 333 Market Street Joint Venture 1800 M Street Joint Venture 2018 2017 2016 2,156 $ 1,998 $ 2,122 2,283 784 2,161 1,000 367 417 — — — 7,384 $ 3,782 $ 2,122 $ $ Columbia Property Trust also received reimbursements of property operating costs of $4.2 million, $2.0 million, and $0.5 million for the years ended December 31, 2018, 2017, and 2016, respectively, which are included in other property income revenues in the accompanying consolidated statements of operations.

Line of Credit and Notes Payable As of December 31, 2018 and 2017, Columbia Property Trust had the following line of credit and notes payable indebtedness outstanding (excluding bonds payable; see Note 6, Bonds Payable) in thousands: Facility Revolving Credit Facility $150 Million Term Loan $300 Million Term Loan $300 Million Bridge Loan 263 Shuman Boulevard Building mortgage note One Glenlake Building mortgage note Less: Deferred financing costs related to term loans, bridge loan, and mortgage notes payable Total indebtedness Rate as of December 31, 2018 LIBOR + 90 bp (1) LIBOR + 110 bp (2) LIBOR + 100 bp (3) LIBOR + 110 bp (4) Term Debt or Interest Only Interest only Interest only Interest only January 31, 2024 Interest only November 27, 2018 Outstanding Balance as of December 31, Maturity 2018 2017 January 31, 2023 $ 482,000 $ July 29, 2022 150,000 152,000 150,000 300,000 300,000 49,000 23,176 — — — — 10.55% 5.80% Interest only July 1, 2017 Term debt December 10, 2018 (2,692) (2,991) $ 629,308 $ 971,185 (1) As of December 31, 2018, borrowings under the Revolving Credit Facility, as described below, bear interest at the option of Columbia Property Trust at an alternate base rate, plus an applicable margin ranging from 0.00% to 0.45% for base-rate borrowings, or at LIBOR, as defined in the credit agreement, plus an applicable margin ranging from 0.775% to 1.45% for LIBOR-based borrowings, based on Columbia Property Trust's applicable credit rating. (2) Columbia Property Trust is party to an interest rate swap agreement with a notional amount of $150.0 million, which effectively fixes its interest rate on the $150 Million Term Loan, as further described below, at 3.07% and terminates on July 29, 2022. This interest rate swap agreement qualifies for hedge accounting treatment; therefore, changes in the fair value are recorded as a market value adjustment to interest rate swap in the accompanying consolidated statement of other comprehensive income. (3) As of December 31, 2018, the $300 Million Term Loan bears interest, at Columbia Property Trust's option, an alternate base rate, plus an applicable margin ranging from 0.00% to 0.65% for base-rate loans, or at LIBOR, as defined in the credit agreement, plus an applicable margin ranging from 0.85% to 1.65% for LIBOR loans, based on Columbia Property Trust's applicable credit rating. (4) The $300 Million Bridge Loan bore interest, at Columbia Property Trust's option, at LIBOR, as defined in the credit agreement, plus an applicable margin ranging from 0.90% to 1.75% for LIBOR loans, or an alternate base rate, plus an applicable margin ranging from 0.00% to 0.75% for base-rate loans, based on Columbia Property Trust's applicable credit rating. Term Loan and Line of Credit Amendment and Restatement On December 7, 2018, Columbia Property Trust amended and restated its existing $500.0 million revolving credit facility and $300.0 million unsecured term loan (together, the "Credit Agreement"), both previously dated July 30, 2015. The Credit Agreement provides for (a) a $650.0 million unsecured revolving credit facility, with an initial term ending January 31, 2023 and two, six- month extension options (for a total possible extension option of one year to January 31, 2024) (the "Revolving Credit Facility"), subject to the paying of certain fees and the satisfaction of certain other conditions, and (b) a delayed-draw, $300.0 million unsecured term loan, with a term ending January 31, 2024 (the "$300 Million Term Loan"). Prior to amendment and restatement, the Revolving Credit Facility and $300 Million Term Loan were set to mature on July 31, 2019 and July 31, 2020, respectively; and the Revolving Credit Facility had a capacity of $500.0 million. At Columbia Property Trust's option, borrowings under the Credit Agreement bear interest at either (i) the alternate base rate plus an applicable margin based on five stated pricing levels ranging from 0.00% to 0.45% for the Revolving Credit Facility and 0.00% to 0.65% for the Term Loan, or (ii) the LIBOR rate, as defined in the credit agreement, plus an applicable margin based on five stated pricing levels ranging from 0.775% to 1.45% for the Revolving Credit Facility and 0.85% to 1.65% for the $300 Million Term Loan, in each case based on the Columbia Property Trust's credit rating. Prior to amendment and restatement, the credit facilities bore interest at either (i) the alternate base rate plus an applicable margin ranging from 0.00% to 0.55% for the Revolving Credit Facility and 0.00% to 0.75% for the $300 Million Term Loan, (ii) the LIBOR rate plus an applicable margin ranging from 0.875% to 1.55% for the Revolving Credit Facility and 0.90% to 1.75% for the $300 Million Term Loan, in each case, based on the Columbia Property Trust's credit rating. In conjunction with amending and restating the Credit Agreement on December 7, 2018, Columbia Property Trust drew on the Revolving Credit Facility to fully prepay the $300.0 million outstanding on the $300 Million Term Loan, without premium or penalty, as provided for in the Credit Agreement. Columbia Property Trust has until December 7, 2019 to draw proceeds on the F-23 $300 Million Term Loan. Subject to customary conditions, including the absence of any default or event of default and financial covenant compliance, Columbia Property Trust has the ability, on up to four occasions, to increase the existing revolving commitment and/or establish one or more new term loan commitments, by an aggregate amount not to exceed $500.0 million. $300 Million Bridge Loan On November 27, 2017, Columbia Property Trust entered into a $300.0 million, one-year, unsecured loan (the "$300 Million Bridge Loan"). The proceeds from the $300 Million Bridge were used to repay borrowings under the Revolving Credit Facility, which were used to fund real estate acquisitions. As further described below, on February 2, 2018 and May 30, 2018, Columbia Property Trust made payments of $120.0 million and $180.0 million, respectively, to fully repay the $300 Million Bridge Loan. Debt Covenants As of December 31, 2018, the $300 Million Term Loan, the $150 Million Term Loan, and the Revolving Credit Facility (collectively, the "Debt Facilities") contain representations and warranties, financial and other affirmative and negative covenants, events of defaults, and remedies typical for these types of facilities. The financial covenants as defined in the Debt Facilities: • • • • • limit the ratio of secured debt to total asset value to 40% or less; require the fixed charge coverage ratio to be at least 1.50:1.00; limit the ratio of debt to total asset value to 60% or less, or 65% or less following a material transaction; require the unencumbered interest coverage ratio to be at least 1.75:1.00; and limit the unencumbered leverage ratio to 60% or less, or 65% or less following a material transaction. As of December 31, 2018, Columbia Property Trust was in compliance with the restrictive financial covenants on its Debt Facilities and notes payable obligations. Fair Value of Debt The estimated fair value of Columbia Property Trust's consolidated line of credit and notes payable as of December 31, 2018 and 2017, was approximately $632.1 million and $975.3 million, respectively. The related carrying value of the line of credit and notes payable as of December 31, 2018 and 2017, was $632.0 million and $974.2 million, respectively. Columbia Property Trust estimated the fair value of its line of credit by obtaining estimates for similar facilities from multiple market participants as of the respective reporting dates. Therefore, the fair values determined are considered to be based on observable market data for similar instruments (Level 2). The fair values of all other debt instruments were estimated based on discounted cash flow analyses using the current incremental borrowing rates for similar types of borrowing arrangements as of the respective reporting dates (Level 3). Interest Paid and Capitalized As of December 31, 2018 and 2017, Columbia Property Trust's weighted-average interest rate on its consolidated line of credit and notes payable was approximately 3.26% and 3.16%, respectively. Columbia Property Trust made interest payments of approximately $22.1 million, $21.5 million, and $27.8 million during 2018, 2017, and 2016, respectively. Columbia Property Trust capitalizes interest on development, redevelopment, and improvement projects owned directly and through unconsolidated joint ventures, using the weighted-average interest rate of its consolidated borrowings for the period. During 2018, 2017, and 2016, Columbia Property Trust capitalized interest of $4.0 million, $0.7 million, and $0.3 million, respectively. For 2018, the weighted average interest rate on Columbia Property Trust’s outstanding borrowings was 3.57%. Debt Repayments and Extinguishment During 2018 and 2017 Columbia Property Trust made the following debt repayments: • On December 7, 2018, concurrent with closing on the Credit Agreement, Columbia Property Trust repaid the $300.0 million remaining balance on the $300 Million Term Loan, which, as described above, includes a delayed-draw feature, allowing up to 12 months to fully draw the term loan. • On October 10, 2018, Columbia Property Trust repaid the $20.7 million outstanding balance on the One Glenlake mortgage note two months prior to its original maturity date. F-24 • On April 13, 2018, Columbia Property Trust transferred 263 Shuman Boulevard to the lender in extinguishment of the $49.0 million loan principal, accrued interest expense, and accrued property operating expenses, which resulted in a gain on extinguishment of debt of $24.0 million in the second quarter of 2018. • On February 2, 2018, Columbia Property Trust repaid $120.0 million of the outstanding balance on the $300 Million Bridge Loan, using a portion of the proceeds from the February 2018 Allianz Transaction, as described in Note 3, Real Estate Transactions. On May 30, 2018, Columbia Property Trust repaid the remaining $180.0 million outstanding balance on the $300 Million Bridge Loan, using a portion of the proceeds from the sale of 222 East 41st Street, as described in Note 3, Real Estate Transactions. As a result, Columbia Property Trust has recognized a loss on extinguishment of debt of $0.3 million related to unamortized deferred financing costs. • On August 17, 2017, Columbia Property Trust repaid the $124.8 million balance of the 650 California Street building mortgage note, which was originally scheduled to mature on July 1, 2019. Columbia Property Trust recognized a loss on extinguishment of debt of $0.3 million related to unamortized deferred financing costs. • On March 10, 2017, Columbia Property Trust repaid the $73.0 million balance of the 221 Main Street building mortgage note, which was originally scheduled to mature on May 10, 2017. Columbia Property Trust recognized a loss on extinguishment of debt of $45,000 related to unamortized deferred financing costs. The following table summarizes the aggregate maturities of Columbia Property Trust's line of credit and notes payable as of December 31, 2018 (in thousands): 2019 2020 2021 2022 2023 Thereafter Total 6. Bonds Payable $ — — — 150,000 482,000 — $ 632,000 Columbia Property Trust has two series of bonds outstanding as of December 31, 2018 and 2017: $350 million of 10-year, unsecured 3.650% senior notes issued at 99.626% of their face value (the "2026 Bonds Payable"); and $350.0 million of 10-year, unsecured 4.150% senior notes issued at 99.859% of their face value (the "2025 Bonds Payable"). Both series of bonds require semi-annual interest payments. Upon issuance, a portion of the 2026 Bonds Payable was used to redeem $250.0 million of bonds payable, due in April 2018. During the years ended December 31, 2018 and 2017, Columbia Property Trust made interest payments of $27.3 million and $27.4 million, respectively, on its bonds payable. The principal amount of the 2026 Bonds Payable is due and payable on August 15, 2026, and the principal amount of the 2025 Bonds Payable is due and payable on April 1, 2025. The 2026 Bonds Payable and the 2025 Bonds Payable contain certain restrictive covenants. These covenants, as defined, pursuant to an indenture: • • • • limit the ratio of debt to total assets to 60%; limit Columbia Property Trust's ability to incur debt if the consolidated income available for debt service to annual debt service charge for four previous consecutive fiscal quarters is less than 1.50:1:00 on a pro forma basis; limit Columbia Property Trust's ability to incur liens if, on an aggregate basis for Columbia Property Trust, the secured debt amount would exceed 40% of the value of the total assets; and require that the ratio of unencumbered asset value, as defined, to total unsecured debt be at least 150% at all times. As of December 31, 2018, Columbia Property Trust was in compliance with the restrictive financial covenants on its 2026 Bonds Payable and 2025 Bonds Payable. The estimated fair value of the 2025 Bonds Payable and the 2026 Bonds Payable as of December 31, 2018 and 2017, was approximately $685.0 million and $702.8 million, respectively. The related carrying value of the bonds payable, net of discounts, as of December 31, 2018 and 2017, was $698.7 million and $698.5 million, respectively. Columbia Property Trust estimated the fair value of the bonds payable based on a discounted cash flow analysis, using observable market data for its bonds payable and similar instruments (Level 2). The discounted cash flow method of assessing fair value results in a general approximation of value, which may differ from the price that could be achieved in a market transaction. F-25 7. Commitments and Contingencies Commitments Under Existing Lease Agreements Certain lease agreements include provisions that, at the option of the tenant, may obligate Columbia Property Trust to expend capital to expand an existing property or provide other expenditures for the benefit of the tenant. As of December 31, 2018, Columbia Property Trust has two material tenant obligations which have arisen in the normal course of business, as follows: $24.1 million related to the WeWork lease at 149 Madison; and $22.3 million related to the Arby's lease at One & Three Glenlake. Such amounts are payable as incurred, and therefore no accrual is booked as of December 31, 2018. Obligations Under Operating Leases Columbia Property Trust owns certain properties that are subject to ground leases with expirations in 2077, 2099, and 2103. The lease expiring in 2077 has been fully prepaid. Columbia Property Trust also leases space for its corporate office. Columbia Property Trust incurred $1.9 million, $2.6 million, and $2.6 million in rent expense related to such leases in 2018, 2017, and 2016, respectively. As of December 31, 2018, the required payments under the terms of the remaining consolidated ground leases and the corporate office lease are as follows (in thousands): 2019 2020 2021 2022 2023 Thereafter Total $ $ 2,502 2,539 2,704 2,743 2,023 176,782 189,293 Guaranties of Debt of Unconsolidated Joint Ventures Columbia Property Trust guarantees portions of the debt at two of its unconsolidated joint ventures. • As of December 31, 2018, Columbia Property Trust guaranteed $5.8 million of the $325.0 million Market Square mortgage loan. This guarantee will continue to be reduced as additional leases are executed at the Market Square property. Columbia Property Trust believes that the likelihood of making a payment under this guaranty is remote; therefore, no liability has been recorded related to this guaranty as of December 31, 2018. • As of December 31, 2018, the 799 Broadway Joint Venture has $101.1 million in outstanding borrowings on the Construction Loan, as further described in Note 4, Unconsolidated Joint Ventures. Pursuant to a joint and several guaranty agreement with the Construction Loan lender, Columbia Property Trust and Normandy are required to make aggregate additional equity contributions to the joint venture based on the initial expected project costs, less the amount of equity contributions made to date. As of December 31, 2018, the remaining equity contribution requirement is $50.9 million, of which $25.3 million reflects Columbia Property Trust's allocated share. Equity contributions become payable by Columbia Property Trust to the joint venture when a capital call is received. As of December 31, 2018, no capital calls remain unpaid; therefore, no liability has been recorded related to this guaranty. Litigation Columbia Property Trust is subject to various legal proceedings, claims, and administrative proceedings arising in the ordinary course of business, some of which are expected to be covered by liability insurance. Management makes assumptions and estimates concerning the likelihood and amount of any reasonably possible loss relating to these matters using the latest information available. Columbia Property Trust records a liability for litigation if an unfavorable outcome is probable and the amount of loss or range of loss can be reasonably estimated. If an unfavorable outcome is probable and a reasonable estimate of the loss is a range, Columbia Property Trust accrues the best estimate within the range. If no amount within the range is a better estimate than any other amount, Columbia Property Trust accrues the minimum amount within the range. If an unfavorable outcome is probable but the amount of the loss cannot be reasonably estimated, Columbia Property Trust discloses the nature of the litigation and indicates that an estimate of the loss or range of loss cannot be made. If an unfavorable outcome is reasonably possible and the estimated loss is material, Columbia Property Trust discloses the nature and estimate of the possible loss of the litigation. Columbia Property Trust does not disclose information with respect to litigation where the possibility of an unfavorable outcome is considered to be remote. Based on current expectations, such matters, both individually and in the aggregate, are not expected to have a material adverse effect on the liquidity, results of operations, business, or financial condition of Columbia Property Trust. Columbia Property Trust F-26 is not currently involved in any legal proceedings of which management would consider the outcome to be reasonably likely to have a material adverse effect on the results of operations or financial condition of Columbia Property Trust. 8. Equity Common Stock Repurchase Program Columbia Property Trust's board of directors authorized the repurchase of up to an aggregate of $200.0 million of its common stock, par value $0.01 per share, from September 4, 2015 through September 4, 2017 (the "2015 Stock Repurchase Program"). Under the 2015 Stock Repurchase Program, Columbia Property Trust acquired 5.6 million shares at an average price of $21.85 per share, for aggregate purchases of $121.4 million. Columbia Property Trust's board of directors authorized a second stock repurchase program to purchase up to an aggregate of $200.0 million of its common stock, par value $0.01 per share, from September 4, 2017 through September 4, 2019 (the "2017 Stock Repurchase Program"). During 2018, Columbia Property Trust repurchased 3.2 million shares at an average price of $21.73 per share, for aggregate purchases of $70.4 million under the 2017 Stock Repurchase Program. As of December 31, 2018, $124.4 million remains available for repurchases under the 2017 Stock Repurchase Program. Common stock repurchases are charged against equity as incurred, and the repurchased shares are retired. Columbia Property Trust will continue to evaluate the purchase of shares, primarily through open market transactions, which are subject to market conditions and other factors. Long-Term Incentive Plan Employee Awards Columbia Property Trust maintains a stockholder-approved, long-term incentive plan that provides for grants of stock to be made to certain employees and independent directors of Columbia Property Trust (as amended and restated, the "LTI Plan"). In May 2017, Columbia Property Trust's stockholders approved the LTI Plan, and 4.8 million shares are authorized and reserved for issuance under the LTI Plan. For 2016, Columbia Property Trust granted 193,535 shares of common stock to employees in January 2017, net of 17,938 shares withheld to settle the related tax liability, under the LTI Plan, of which 25% vested upon grant; the remaining shares will vest ratably, with the passage of time, on January 31, 2018, 2019, and 2020. Employees receive quarterly dividends related to their entire grant, including the unvested shares, on each dividend payment date. For 2017, Columbia Property Trust modified the structure of awards granted under the LTI Plan to include both time-based awards and performance-based awards for all participants. For the 2017 time-based awards, Columbia Property Trust issued 139,825 shares of common stock to employees, which will vest ratably on each anniversary of the grant date over the next four years. For the 2017 performance-based awards, Columbia Property Trust granted 193,219 restricted stock units (the "Performance-Based RSUs"), of which 75% will vest at the conclusion of a three-year performance period, and the remaining 25% will vest one year later. In addition, Columbia Property Trust granted 45,076 and 92,585 one-time transitional Performance-Based RSUs, which will fully vest at the conclusion of one-year and two-year performance periods, respectively. Upon reaching a predefined performance threshold, the payout of the Performance-Based RSUs will range from 50% to 150% of the Performance-Based RSUs granted, depending on Columbia Property Trust's total stockholder return relative to the FTSE NAREIT Equity Office Index. All awards are expensed over the vesting period based on their estimated fair values. The fair value of time-based awards is estimated using the closing stock price on the grant date; and fair values of performance-based awards are estimated using a Monte Carlo valuation method. The 2018 LTI Plan awards are consistent with the 2017 LTI Plan awards. On January 1, 2018, Columbia Property Trust granted 128,486 shares of time-based stock awards to employees, which will vest ratably on each anniversary of the grant over the next four years. On January 1, 2018, Columbia Property Trust granted 176,702 Performance-Based RSUs, of which 75% will vest at the conclusion of a three-year performance period, and the remaining 25% will vest one year later. Consistent with the 2017 awards, the payout of the 2018 Performance-Based RSUs will be determined based on Columbia Property Trust's total stockholder return relative to the FTSE NAREIT Equity Office Index. The 2019 LTI Plan awards are consistent with the 2018 LTI Plan awards. On January 1, 2019, Columbia Property Trust granted 175,129 shares of time-based stock awards to employees, which will vest ratably on each anniversary of the grant over the next four years. On January 1, 2019, Columbia Property Trust granted 221,199 Performance-Based RSUs, of which 75% will vest at the conclusion of a three-year performance period, and the remaining 25% will vest one year later. Consistent with the 2018 awards, the payout of the 2019 Performance-Based RSUs will be determined based on Columbia Property Trust's total stockholder return relative to the FTSE NAREIT Equity Office Index.

Director Stock Grants Columbia Property Trust grants equity retainers to its directors under the LTI Plan. Such grants vest immediately. Beginning in May 2017, these grants are made annually for the following year. Prior to this time, the independent directors' equity retainers were paid quarterly. A summary of these grants, made under the LTI Plan for 2018, 2017, and 2016, follows: Date of Grant 2018 Director Grants: May 14, 2018 2017 Director Grants: January 3, 2017 May 2, 2017 November 27, 2017(2) 2016 Director Grants: January 4, 2016 April 1, 2016 July 1, 2016 October 3, 2016 Shares Weighted-Average, Grant-Date Fair Value(1) 31,743 8,279 33,581 1,596 7,439 8,120 8,158 7,727 $ $ $ $ $ $ $ $ 22.20 21.58 22.57 23.07 23.00 21.89 21.52 22.19 (1) Columbia Property Trust determined the weighted-average grant-date fair value using the market closing price on the date of the grant.

These expenses are included in general and administrative expenses – corporate in the accompanying consolidated statements of operations. There were $8.6 million and $8.1 million of unrecognized compensation costs related to unvested awards under the LTI Plan as of December 31, 2018 and December 31, 2017, respectively. This amount will be amortized over the respective vesting period, ranging from one year to four years at the time of grant. Independent Director Stock Option Plan Columbia Property Trust previously maintained an independent director stock option plan that provides for grants of stock to be made to independent directors of Columbia Property Trust (the "Director Plan"). A total of 25,000 shares were authorized and reserved for issuance under the Director Plan, which was suspended in April of 2008. Under the Director Plan, options were granted upon appointment to the board and on each annual meeting date. As of December 31, 2015, Columbia Property Trust had 1,875 options outstanding under this plan, with an exercise price of $48.00, of which 500 options expired in 2016, and the remaining 1,375 options expired in 2017. There are no remaining options outstanding under the Director Plan. 9. Operating Leases Columbia Property Trust's real estate assets are leased to tenants under operating leases for which the terms vary, including certain provisions to extend the lease agreement, options for early terminations, subject to specified penalties, and other terms and conditions as negotiated. Columbia Property Trust retains substantially all of the risks and benefits of ownership of the real estate assets leased to tenants. Amounts required as security deposits vary depending upon the terms of the respective leases and the creditworthiness of the tenant; however, such deposits generally are not significant. Therefore, exposure to credit risk exists to the extent that the receivables exceed this amount. Security deposits related to tenant leases are included in accounts payable, accrued expenses, and accrued capital expenditures in the accompanying consolidated balance sheets. Based on 2018 annualized lease revenue, none of Columbia Property Trust's tenants represent more than 6% of Columbia Property Trust's portfolio. Tenants in business services, depository institutions, and engineering and management services represent 24%, 10%, and 7%, respectively, of Columbia Property Trust's annualized lease revenue. Columbia Property Trust's properties are located primarily in three markets. As of December 31, 2018, approximately 37%, 26%, and 15% of Columbia Property Trust's office properties are located in New York, San Francisco, and Washington, D.C., respectively, based on annualized lease revenue. The future minimum rental income from Columbia Property Trust's investment in real estate assets under noncancelable operating leases, excluding lease incentives, as of December 31, 2018, is as follows (in thousands): 2019 2020 2021 2022 2023 Thereafter Total $ $ 242,370 247,826 221,692 209,845 192,261 1,106,275 2,220,269 F-29 10.

F-32 14. Non-Lease Revenues On January 1, 2018, Columbia Property Trust adopted ASU 2014-09, which applies to the non-lease revenue streams outlined below. ASU 2014-09 requires companies to perform a five-step analysis of transactions to determine when and how revenue is recognized. See Note 2, Summary of Significant Accounting Policies, for information about revenues earned under leases. Asset and Property Management Fee Income Under asset and property management agreements in place with certain of its unconsolidated joint ventures, Columbia Property Trust earns revenue for performing asset and property management functions for properties owned through its joint ventures, as further described in Note 4, Unconsolidated Joint Ventures. During 2018, 2017, and 2016, Columbia Property Trust earned revenues of $7.4 million, $3.8 million, and $2.1 million, respectively, under these agreements. Asset and property management services are ongoing and routine, and are provided on a recurring basis. Therefore, under ASU 2014-09, such fees are recognized ratably over the service period, usually a period of three months, which is consistent with the accounting method used prior to January 1, 2018. Columbia Property Trust receives payments quarterly for asset management fees and monthly for property management fees. Leasing Override Fees Under the asset management agreements for certain properties owned through unconsolidated joint ventures, Columbia Property Trust is eligible to earn leasing override fees equal to a percentage of the total rental payments to be made by the tenant over the term of the lease. ASU 2014-09 requires such fees to be recognized when Columbia Property Trust's obligation to perform is complete, typically upon execution of the lease. Prior to January 1, 2018, such fees were not recognized until billable to the applicable joint venture, typically upon commencement of the lease. Upon implementing ASU 2014-09, effective January 1, 2018, Columbia Property Trust accelerated the recognition of lease override fees related to a lease that had been executed but not yet commenced, by recording $0.3 million of lease override fees receivable as prepaid expenses and other assets and a cumulative- effect adjustment to increase equity by the same amount. During 2018, Columbia Property Trust earned leasing override fees of $0.2 million, which are included in asset and property management fee income on the accompanying consolidated statements of operations. During 2017 and 2016, Columbia Property Trust did not earn any leasing override fees. Salary and Other Reimbursement Revenue Under the property management agreements for certain properties owned through unconsolidated joint ventures, Columbia Property Trust receives reimbursements for salaries and property operating costs for ongoing and routine services that are provided by Columbia Property Trust employees on a recurring basis. Under ASU 2014-09, such revenues are recognized ratably over the service period, usually a period of one month, three months, or one year, which is consistent with the accounting method used prior to January 1, 2018. During 2018, 2017, and 2016, Columbia Property Trust earned salary and other reimbursement revenue of $4.4 million, $2.3 million, and $0.7 million, respectively. These amounts are included in other property income on the accompanying consolidated statements of income. Miscellaneous Revenue Columbia Property Trust also receives revenues for services provided to its tenants through the TRS Entities, including fitness centers, shuttles, and cafeterias, which are included in other property income on the accompanying consolidated statements of income. Such services are ongoing and routine, and are provided on a recurring basis. Under ASU 2014-09, these revenues are recognized ratably over the service period, usually a period of one month or one quarter, which is consistent with the accounting method used prior to January 1, 2018. During 2018, 2017, and 2016, Columbia Property Trust earned miscellaneous revenue of $0.7 million, $0.6 million, and $0.7 million, respectively. These amounts are included in other property income on the accompanying consolidated statements of income. Prior to disposition on January 31, 2017, Columbia Property Trust owned the Key Center Marriott, a full-service hotel, through a taxable REIT subsidiary. Revenues derived from the operations of the hotel include, but are not limited to, revenues from rental of rooms, food and beverage sales, telephone usage, and other service revenues. Revenue was recognized when rooms were occupied, when services performed, and when products were delivered. 15. Segment Information Columbia Property Trust establishes operating segments at the property level, and aggregates individual properties into reportable segments for high-barrier-to-entry markets and other geographic locations in which Columbia Property Trust has significant investments. Columbia Property Trust considers geographic location when evaluating its portfolio composition, and in assessing the ongoing operations and performance of its properties. As of December 31, 2018, Columbia Property Trust had the following reportable segments: New York, San Francisco, Atlanta, Washington, D.C., Boston, Los Angeles, and all other office markets. The all other office markets reportable segment consists of properties in similar low-barrier-to-entry geographic locations in which F-33 Columbia Property Trust does not have a substantial presence and does not plan to make further investments. During the periods presented, there have been no material intersegment transactions. Net operating income ("NOI") is a non-GAAP financial measure and is not considered a measure of operating results or cash flows from operations under GAAP. NOI is the primary performance measure reviewed by management to assess operating performance of properties and is calculated by deducting operating expenses from operating revenues. Operating revenues include rental income, tenant reimbursements, hotel income, and other property income; and operating expenses include property and hotel operating costs. The NOI performance metric consists of only revenues and expenses directly related to real estate rental operations. NOI reflects property acquisitions and dispositions, occupancy levels, rental rate increases or decreases, and the recoverability of operating expenses. NOI, as Columbia Property Trust calculates it, may not be directly comparable to similarly titled, but differently calculated, measures for other REITs. Asset information and capital expenditures by segment are not reported because Columbia Property Trust does not use these measures to assess performance. Depreciation and amortization expense, along with other expense and income items, are not allocated among segments.

Financial Information for Parent Guarantor, Other Guarantor Subsidiaries, and Non-Guarantor Subsidiaries The 2026 Bonds Payable and the 2025 Bonds Payable (see Note 6, Bonds Payable) were issued by Columbia Property Trust OP, and are guaranteed by Columbia Property Trust. In accordance with SEC Rule 3-10(c), Columbia Property Trust includes herein condensed consolidating financial information in lieu of separate financial statements of the subsidiary issuer (Columbia Property Trust OP), as defined in the bond indentures, because all of the following criteria are met: F-35 (1) the subsidiary issuer (Columbia Property Trust OP) is 100% owned by the parent company guarantor (Columbia Property Trust); (2) the guarantees are full and unconditional; and (3) no other subsidiary of the parent company guarantor (Columbia Property Trust) guarantees the 2026 Bonds Payable or the 2025 Bonds Payable. Columbia Property Trust uses the equity method with respect to its investment in subsidiaries included in its condensed consolidating financial statements. Columbia Property Trust has corrected the presentation of intercompany cash transfers between the REIT Parent and its subsidiaries in the consolidating statements of cash flow. Instead of showing one amount for intercompany transfers between each entity group, intercompany transfers are broken out by cash flow type (i.e., operating, investing, and financing) for all periods presented, consistent with the equity method of accounting. All such changes are eliminated in consolidation and therefore do not impact Columbia Property Trust's consolidated financial statement totals. Management has concluded that the effect of this correction is not material to the consolidated financial statements. This change had the following impact to the condensed consolidating statement of cash flows for the year ended December 31, 2016: increase to operating cash flows for the parent and issuer of $53.1 million and $136.7 million, respectively; and increase (decrease) in investing cash flows for the parent, issuer, and non-guarantors of $(281.8) million, $568.5 million, and $603.7 million, respectively; and increase (decrease) in financing cash flows for the parent, issuer, and non-guarantors of $228.7 million, $(705.2) million, and $(603.7) million, respectively. The impact to individual financial statement captions within the condensed consolidating statement of cash flows is footnoted below. Set forth below are Columbia Property Trust's condensed consolidating balance sheets as of December 31, 2018 and 2017, as well as its condensed consolidating statements of operations and its condensed consolidating statements of comprehensive income for 2018, 2017, and 2016; and its condensed consolidating statements of cash flows for 2018, 2017, and 2016.
