PART I
ITEM 1.
BUSINESS
General
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, redevelops, owns, leases, and operates real properties directly, through wholly owned subsidiaries, and through unconsolidated joint ventures. Unless otherwise noted herein, 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 invests in high-quality, income-generating office properties. As of December 31, 2017, Columbia Property Trust owned 19 operating properties, of which 14 were wholly owned and five 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 9.2 million rentable square feet, and were approximately 96.2% leased as of December 31, 2017.
Real Estate Investment Objectives
Columbia Property Trust seeks to invest in 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 shareholders. Our primary strategic objective is to generate long-term shareholder 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 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 central business districts 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 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.
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.

On February 1, 2018, we sold an additional 22.5% interest in both University Circle and 333 Market Street to our joint venture partner, Allianz for $235.3 million, as described in Note 3, Real Estate Transactions, of the accompanying consolidated financial statements.

Sale price is for our partial interest in the property.  On October 28, 2015, Columbia Property Trust transferred the Market Square properties, valued at $595.0 million and subject to a $325.0 million mortgage note, to a joint venture and sold a 49% interest in that joint venture to Blackstone Property Partners for net proceeds of approximately $120.0 million.  See Note 3, Real Estate Transactions, and Note 4, Unconsolidated Joint Ventures for additional information.
Segment Information
As of December 31, 2017, our reportable segments are determined based on the 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 14, Segment Information, to the accompanying consolidated financial statements.

Employees
As of December 31, 2017, we employed 94 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 current tenants to pay their contractual rent amounts as they become due. The inability of a tenant to pay future rental amounts would have a negative 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. Situations preventing our tenants from paying contractual rents could result in a material adverse impact on our results of operations. Based on our 2017 annualized lease revenue, no single tenant accounts for more than 6% of our portfolio.
Website Address
Access to copies of each of our annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, proxy statements, and other documents filed with, or furnished to, the SEC, including amendments to such filings, may be obtained free of charge from our website, http://www.columbia.reit, or through a link to the http://www.sec.gov website. The information contained on our website is not incorporated by reference herein. These filings are available promptly after we file them with, or furnish them to, the SEC.
ITEM 1A.
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 pay too much for properties, we may not be able to achieve our investment objectives, and the returns on our investments will be lower than they otherwise would be.
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 our profitability and our ability to pay distributions to stockholders. We cannot be sure that we will be successful in obtaining suitable investments on financially attractive terms or that, if we make investments, our objectives will be achieved.
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 2017, 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 96.2% leased at December 31, 2017, 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 2017 annualized lease revenue,


Page 7

Table of Contents
Index to Financial Statements

approximately 2% of leases expire in 2018, 3% of leases expire in 2019, and 7% of leases expire in 2020 (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 redevelopment 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 Fransisco; Washington, D.C.; Boston; 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 City, New York; San Francisco, California; Washington, D.C.; Boston, Massachusetts; and Atlanta, Georgia, 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.
We depend on tenants for our revenue, and lease defaults or terminations 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 mortgage payments and prevent a foreclosure if the property is subject to a mortgage, could cause us to violate our bank debt covenants, or 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.
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 additional properties. Acquired 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 in bringing an acquired 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 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 acquired 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 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 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.
Real estate investments are illiquid; our inability to sell a property when we plan to do so could limit our operational and financial flexibility, including our ability to pay cash distributions to our stockholders.
Because real estate investments are relatively illiquid, our ability to sell promptly 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, 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. Furthermore, our properties' market values depend principally upon the value of the properties' 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.
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 28% of our 2017 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 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 are likely to continue to incur mortgage and other indebtedness, which may increase our business risks.
As of February 2, 2018, our total consolidated indebtedness was approximately $1.5 billion, which includes a $150.0 million term loan, $700.0 million of bonds, and $71.9 million of mortgage loans, all with fixed interest rates, or with interest rates that are effectively fixed when considered in connection with an interest rate swap agreement; and $180.0 million outstanding on a bridge loan, a $300.0 million term loan, and $60.0 million in outstanding borrowings on our line of credit, all with variable interest rates. We are likely to incur additional indebtedness to acquire 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 mortgages or other indebtedness contain 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 three 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, to finance or refinance properties, which could reduce the number of properties we can acquire, our net income, and the amount of cash distributions we can make.
We expect to incur additional indebtedness in the future, which may include mortgages, unsecured bonds, term loans, or borrowings under a credit facility. 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. 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, 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 loan, 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.
A breach of our privacy or information security systems 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 to our systems, both internal and those we have outsourced. 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. Although we make efforts to maintain the security and integrity of these types of information technology networks and related systems, there can be no assurance that our security efforts and measures will be effective or that attempted security breaches or disruptions would not be successful or damaging. 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, including 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.
Property ownership through joint ventures may limit our ability to act exclusively in our interest.
We have entered into five joint venture arrangements and in the future may acquire 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 risk in cases where an institutional owner is our joint venture partner, including (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.
Our operating results may suffer because of potential development and construction risks and delays and resultant increased costs.
We may acquire and redevelop properties, including unimproved real estate, upon which we will construct improvements. We will be subject to uncertainties associated with rezoning for development and our ability to obtain required permits and authorizations; environmental concerns of governmental entities and/or community groups; and our contractors' abilities to build in conformity with plans, specifications, budgeted costs, and timetables. If a contractor fails to perform, we may resort to legal action to rescind the purchase or the construction contract or to compel performance. A contractor's performance may also be affected or delayed by conditions beyond the contractor's control, and we may incur additional risks when we make periodic progress payments or other advances to contractors before they complete construction. Delays in completing construction could also give tenants the right to terminate preconstruction leases. These and other factors can result in increased costs of a project or loss of our investment.


Page 12

In addition, we will be subject to normal lease-up risks relating to newly constructed projects. We must rely on rental income and expense projections and estimates of the fair market value of property upon completion of construction when agreeing upon a purchase price at the time we acquire the property. If our projections are inaccurate, we may pay too much for a property, and our return on our investment could suffer.
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.
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


Page 13

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 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.


Page 14

Table of Contents
Index to Financial Statements

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, H.R. 1, which generally takes effect for taxable years beginning on or after January 1, 2018 (subject to certain exceptions), 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 shareholders in various ways, some of which are adverse or potentially adverse compared to prior law. To date, the IRS has issued only limited guidance with respect to certain of the new provisions, and there are numerous interpretive issues that will require 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.
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 H.R. 1 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. H.R. 1 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.

PROPERTIES
Overview
As of December 31, 2017, we owned 19 operating properties, of which 14 were wholly owned and five were owned through unconsolidated joint ventures. These properties are located primarily in New York, San Francisco, Washington, D.C., and Atlanta and were approximately 96.2% leased as of December 31, 2017.
Property Statistics
The tables below include statistics for the 14 operating properties that we own directly and our proportional share of the annualized lease revenue and rentable square feet for the five properties we own through unconsolidated joint ventures. 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, 2017, as well as leases executed but not yet commenced for vacant space, and (ii) annualized parking revenues, payable either under the terms of an executed lease or vendor contract ("Annualized Lease Revenue"). Annualized Lease Revenue excludes rental payments for executed leases that have not yet commenced for space covered by an existing lease.

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. In determining the amount of distributions to common stockholders, we also consider 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, as well as equity repurchases, are generally funded with recycled capital proceeds from property sales, debt, or cash on hand.

Performance Graph
The following graph compares the cumulative total return of our common stock with the S&P 500 Index, Morgan Stanley REIT Index, and the FTSE NAREIT US Real Estate Index for the period beginning on October 10, 2013 (the date of our initial listing on the NYSE) through December 31, 2016. Beginning with the year-ended December 31, 2017, we have selected the FTSE NAREIT Equity Office Index to replace the FTSE NAREIT US Real Estate Index to measure our relative total stockholder return. The FTSE NAREIT Equity Office Index is used as the basis for measuring our equity compensation. The graph assumes a $100 investment in each of the indices on October 10, 2013, and the reinvestment of all dividends.

ITEM 7.
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 shareholder returns from a combination of growing cash flows and appreciation in the values of our properties, by owning and operating high-quality office properties principally located in high-barrier-to-entry markets. We concentrate on 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.
We recently completed a multi-year capital recycling program that involved selling more than 50 properties in geographically dispersed markets for aggregate proceeds of $3.6 billion, and reinvested this capital in New York, San Francisco, Washington, D.C., and Boston. During the second half of 2017, we executed the following transactions:
On July 6, 2017, we formed a strategic partnership with Allianz Real Estate of America LLC ("Allianz") to increase our operating scale in key markets by freeing-up capital for additional investment. We consummated the partnership by simultaneously selling a 22.5% interest in two of our San Francisco properties, 333 Market Street and University Circle, to Allianz for $234.0 million, and by acquiring a 49.5% interest in 114 Fifth Avenue in Manhattan from Allianz for $108.9 million. In February 2018, we sold an additional 22.5% interest in 333 Market Street and University Circle to Allianz for $235.3 million.
On October 11, 2017, we acquired a 55% interest in 1800 M Street, a 10-story office building in Washington, D.C., for $231.6 million through a joint venture with Allianz.
On October 11, 2017, we acquired 245-249 West 17th Street, two interconnected 12- and six-story towers totaling 281,000 square feet of office and retail space, and 218 West 18th Street, a 12-story, 166,000-square-foot office building, in New York for $514.1 million.
On November 28, 2017, we acquired 149 Madison Avenue in New York, a 12-story, 127,000-square-foot office building for $87.7 million, subject to a ground lease that expired in January 2018. We are planning to redevelop this property.
We will continue to pursue strategic investment opportunities in our target markets, as well as selective property dispositions.
Leasing continues to be a key area of focus for both vacant space and upcoming expirations. During 2017, we have leased over 2.0 million square feet of space and addressed some of our most significant near-term expirations and vacancies:
At University Circle, we executed a five-year, 119,000-square-foot lease renewal with DLA Piper to extend the lease to June 2023 and address our most significant 2018 expiration. At 650 California Street, we executed an eight-year, 86,000-square-foot lease with Affirm; a 22,000-square-foot renewal and expansion with an existing tenant; and a 12-year, 61,000-square-foot lease with WeWork.
In New York, at 229 West 43rd Street, we expanded Snap Inc.'s leased space by 58,000 square feet to a total of 154,000 square feet, and extended the lease to 2032; and at 315 Park Avenue South, executed 68,000 square feet of new leasing, and a 17,000-square-foot lease expansion with Bustle Media Group.
In Atlanta, at One Glenlake, we executed a 10-year, 66,000-square-foot lease, and an 11-year, 40,000-square-foot lease renewal and expansion along with several smaller leases. At Three Glenlake, we executed a 12-year, 161,000-square-foot lease with Arby's. This lease is for a portion of the space vacated by the exisiting tenant, whose lease is expiring in December 2018. As a result of this leasing activity, the One & Three Glenlake property is 99.3% leased at year end.
In Pittsburgh, at Cranberry Woods, we executed a lease renewal and extension with Westinghouse, extending the 824,000-square-foot lease to 2032.

We continue to maintain a strong and flexible balance sheet with a weighted-average cost of borrowing of 3.35%(1) per annum as of December 31, 2017. Our debt capital allocation favors unsecured borrowings with 92%(1) of our portfolio unencumbered by mortgages. Our debt maturities are well-laddered over the next nine years, and $752.0 million of the borrowings outstanding at year-end may be repaid prior to maturity, in part or in full, without penalty. Our stock repurchase program allows us to take advantage of market opportunities from time to time when we believe our stock is undervalued. During 2017, we repurchased $57.6 million of our common stock (2.7 million shares at an average price of $21.46 per share). Since September 2015, under our stock repurchase programs, we have repurchased an aggregate of $121.4 million of common stock at an average price of $21.85 per share.

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; and exclude the 263 Shuman mortgage note, as the note matured in July 2017 and we are in the process of transferring the property to the lender.
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 90.6% at December 31, 2016 to 96.2% at December 31, 2017. The following table sets forth details related to recent leasing activities, which drive changes in our rental revenues:

Rent leasing spreads for renewal leases are calculated based on the change in base rental income measured on a straight-line basis.
(3) 
Rent leasing spreads for new leases are calculated only for space that has been vacant less than one year, and are measured on a straight-line basis.
In 2017, rent leasing spreads have been 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 has required significant tenant improvements; however, the net economic impact of leasing at 650 California Street is favorable. Positive rent leasing spreads for renewal leases are 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 in the fourth quarter of 2017. In 2016, we executed a new 390,000-square-foot, 30-year lease at our 222 East 41st Street property with NYU Langone Medical, which resulted in positive rent leasing spreads of 14.4%, tenant improvements of $180.10 per square foot, and leasing commissions of $44.90 per square foot. Over the next 12 months, approximately 94,000 square feet of our leases (approximately 2% of our office portfolio based on revenues) are scheduled to expire.
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


Page 24

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. In determining the amount of distributions to common stockholders, we also consider 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. We have transformed the composition of our portfolio by selling suburban assets and reinvesting in assets in high-barrier-to-entry markets that offer lower initial yields and higher potential for growth over time. As a result, our board of directors elected to adjust our payout level to be consistent with our current investment objectives, by reducing the quarterly stockholder distribution rate from $0.30 per share to $0.20 per share beginning with the first quarter of 2017. This rate has been maintained through the first quarter of 2018. We believe this dividend rate is sustainable over the near and medium term and offers the potential for growth over the long term.
Investments in new property acquisitions and first-generation capital improvements are generally funded with capital proceeds from property sales, debt, or cash on hand.
Short-Term Liquidity and Capital Resources
During 2017, we generated net cash flows from operating activities of $61.9 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 $109.6 million, which included dividend payments for four quarters ($36.7 million for the fourth quarter of 2016 and an aggregate of $72.9 million for the first three quarters of 2017). Distributions to stockholders exceeded net cash flow from operating activities for 2017 primarily due to the impact of timing differences between selling assets and redeploying capital, and of new and renewal leases in free rent periods. Properties acquired in 2017 and recent leases are expected to contribute to additional cash flow from operations in future periods.
During 2017, we sold five wholly owned properties and partial interests in two additional properties for net proceeds of $737.6 million. We used these proceeds, along with a $300.0 million bridge loan and borrowings on our line of credit, to fund acquisitions of three wholly owned properties for $604.8 million and partial interests in two properties for $353.6 million; the repayment of $197.8 million of mortgage notes; leasing and capital projects at our consolidated and joint venture-owned properties of $129.0 million; and share repurchases of $59.5 million.
Over the short-term, we expect our primary sources of capital to be operating cash flows and debt. We expect that our principal demands for funds will be property acquisitions, capital improvements to our existing portfolio, stock repurchases, stockholder distributions, operating expenses, and interest and principal payments on current and maturing debt. On February 1, 2018, we sold a second 22.5% interest in University Circle and 333 Market Street to our joint venture partner, Allianz, for $235.3 million. We used the proceeds from this transaction to reduce borrowing on our Revolving Credit Facility and the $300 Million Bridge Loan, both described below. We believe that we have adequate liquidity and capital resources to meet our other current obligations as they come due, including our remaining 2018 debt maturities of $202.9 million. As of February 2, 2018, we had access to $440 million of the borrowing capacity under the Revolving Credit Facility.
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 proceeds from secured or unsecured borrowings. We expect that our primary uses of capital will continue to include stockholder distributions; repaying or refinancing debt; acquisitions; and capital expenditures, such as building improvements, tenant improvements, and leasing costs.
Consistent with our financing objectives and operational strategy, we have generally maintained debt levels less than 40% of the cost of our assets. We believe that preserving investor capital while generating stable current income is in the best interest of our stockholders. Our debt-to-real-estate-asset ratio is calculated using the outstanding debt balance and real estate at cost. As of December 31, 2017, our debt-to-real-estate-asset ratio, including 51% of the debt and real estate at the Market Square Joint venture, which we own through an unconsolidated joint venture, was approximately 38.7%.
Bridge Loan
We have a $300.0 million, one-year, unsecured loan (the "$300 Million Bridge Loan"), which is set to mature on November 27, 2018. The $300 Million Bridge Loan bears interest at either (ii) LIBOR, plus an applicable margin ranging from 0.90% to 1.75% for LIBOR loans, or (ii) an alternate base rate, plus an applicable margin ranging from 0.00% to 0.75%. The $300 Million Bridge Loan provides for one six-month extension option to May 24, 2019, subject to certain fees and the satisfaction of certain other conditions.

Revolving Credit Facility
Our Revolving Credit Facility has a capacity of $500.0 million and matures in July 2019, with two six-month extension options. As of December 31, 2017, we had $152.0 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 0.875% to 1.55% for LIBOR borrowings, or an alternate base rate, plus an applicable margin ranging from 0.00% to 0.55% 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, we have the ability to increase the capacity of the Revolving Credit Facility, along with the $300 Million Term Loan, which provides for four accordion options for an aggregate additional amount of up to $400 million, subject to certain limitations.
Term Loans
We have a $300.0 million unsecured term loan, which matures in July 2020 (the "$300 Million Term Loan"), and, along with the Revolving Credit Facility, provides for four accordion options for an aggregate amount of up to $400 million, subject to certain conditions. The $300 Million Term Loan 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) an alternate base rate, plus an applicable margin ranging from 0.00% to 0.75% for base rate loans, based on our applicable credit rating.
We have a $150.0 million unsecured term loan, which matures in July 2022 (the "$150 Million Term Loan"). The $150 Million Term Loan 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%.
Debt Covenants
The $300 Million Term Loan, $300 Million Bridge Loan, the $150 Million Term Loan, and the Revolving Credit Facility contain the following restrictive covenants:
limits the ratio of secured debt to total asset value, as defined therein, to 40% or less;
requires the fixed charge coverage ratio, as defined therein, to be at least 1.50:1.00;
limits the ratio of debt to total asset value, as defined therein, to 60% or less;
requires the ratio of unencumbered adjusted net operating income, as defined therein, to unsecured interest expense, as defined therein, to be at least 1.75:1.00;
requires the ratio of unencumbered asset value, as defined therein, to total unsecured debt, as defined therein, to be at least 1.66:1.00; and
requires maintenance of certain minimum tangible net worth balances.
As of December 31, 2017, we believe 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"). We received proceeds from the 2026 Bonds Payable, net of fees, of $346.4 million, which were used to prepay our $250 million bonds payable, originally due in April of 2018. 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"). We received proceeds from the 2025 Bonds Payable, net of fees, of $347.2 million, a portion of which was used to repay a bridge loan, which was originated in January 2015. 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 1.5:1 on a pro forma basis;


Page 26

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, 2017, we believe we were in compliance with the restrictive covenants on the 2026 Bonds Payable and the 2025 Bonds Payable.
Debt Repayments, Maturities, and Interest Payments
During 2017 and 2016, we made the following debt repayments:
On August 17, 2017, we 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 early extinguishment of debt of $0.3 million related to unamortized deferred financing costs.
On March 10, 2017, we 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 early extinguishment of debt of $45,000 related to unamortized deferred financing costs.
On October 3, 2016, a portion of the proceeds from the sale of the 80 Park Plaza Property was used to repay the $99.0 million remaining outstanding balance on our Revolving Credit Facility.
On September 2, 2016, the proceeds from the 2026 Bonds Payable, as described above, were used to redeem $250.0 million of seven-year, unsecured 5.875% senior notes due April 2018, including a $17.9 million make-whole payment recorded as an early loss on extinguishment of debt in the accompanying consolidated statement of operations.
On June 30, 2016, we used borrowings on the Revolving Credit Facility to repay the $39.0 million SanTan Corporate Center mortgage notes, which were scheduled to mature on October 11, 2016, resulting in the write-off of approximately $10,000 of related unamortized financing costs, which are included in loss on early extinguishment in the accompanying statements of operations.
On April 1, 2016, we repaid the $119.0 million remaining on a $300 million, six-month, unsecured loan, which was used to finance a portion of the 229 West 43rd Street Building acquisition in August of 2015 (the "2015 Bridge Loan"). The 2015 Bridge Loan was scheduled to mature on August 4, 2016. We recognized a loss on early extinguishment of debt of $82,000 related to unamortized deferred financing costs.
During 2017 and 2016, we made interest payments of approximately $21.5 million and $27.8 million, respectively, related to our term loans, line of credit, and notes payable. During 2017 and 2016, we made interest payments of $27.4 million and $28.0 million, respectively, on our bonds payable.

Includes 51% of the debt and interest obligations for the Market Square Joint Venture, which we own through an unconsolidated joint venture. The Market Square Joint Venture has a $325 million mortgage loan on the Market Square Buildings, which bears interest at 5.07% and matures on July 1, 2023. We guarantee $11.2 million of the Market Square Buildings mortgage loan (see Note 7, Commitments & Contingencies, to the accompanying financial statements).

Debt obligations exclude the $49.0 million 263 Shuman Boulevard mortgage note, which matured in July 2017. We are in the process of working to transfer this property to the lender in settlement of the mortgage note.
(3) 
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, 2017. Interest obligations on all other debt instruments are measured at the contractual rate. See Item 7A, Quantitative and Qualitative Disclosure About Market Risk, for more information regarding our interest rate swaps.
(4) 
Amounts include principal obligations only. We made interest payments on these obligations of $7.2 million during 2017, all of which was funded with interest income earned on the corresponding investments in development authority bonds.

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, including a commitment to contribute $54.7 million toward remaining leasehold improvements at our 222 East 41st Street property.
Results of Operations
Overview
As of December 31, 2017, Columbia Property Trust owned 19 operating properties, of which 14 were wholly owned and five were owned through unconsolidated joint ventures. These properties are located primarily in New York, San Francisco, Washington, D.C., and Atlanta, and were approximately 96.2% leased as of December 31, 2017. 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, 2017 Versus the Year Ended December 31, 2016
Rental income was $257.1 million for 2017, which represents a decrease from $366.2 million for 2016. The decrease is primarily due to dispositions ($94.3 million) and transferring University Circle and 333 Market Street to unconsolidated joint ventures ($24.4 million), partially offset by the acquisitions in the fourth quarter of 2017 ($8.4 million). We expect future rental income to vary based on recent and future investing and leasing activities.
Tenant reimbursements and property operating costs were $23.5 million and $87.8 million, respectively, for 2017, which represents a decrease from $69.8 million and $155.0 million, respectively, for 2016. The decrease in tenant reimbursements is primarily due to dispositions ($35.5 million), transferring University Circle and 333 Market Street to unconsolidated joint ventures ($4.9 million), and the new net lease at 222 East 41st Street ($3.3 million). The decrease in property operating costs 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). Tenant reimbursements and property operating costs are expected to vary with future leasing activities and other changes in our portfolio.
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. We anticipate future asset and property management fee income to increase as we earn fees from the newly established joint ventures for full periods (see Note 4, Unconsolidated Joint Ventures).
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. Other property operating income is expected to vary in the future, based on additional lease restructuring activities.
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). 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 $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). Depreciation is expected to vary based on recent and future investing activities.
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). We expect future amortization to vary based on recent and future investing activities.

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). General and administrative expenses corporate are expected to remain at similar levels over the near term; and general and administrative expenses unconsolidated joint ventures are expected to vary as a result of future joint venture activity.
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 expect interest expense to increase in the near term, due to borrowings to fund recent investing activities.
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 with a remaining term of approximately four years as of December 31, 2017. Interest income earned on investments in development authority bonds is entirely offset by interest expense incurred on the corresponding capital leases. We expect interest and other income to decrease slightly over the near term as cash deposits were applied to recent investing activities.
We recognized a loss on early extinguishment of debt of $0.3 million and $19.0 million in 2017 and 2016, respectively. In 2017, we repaid two mortgage notes. resulting in the write-off of the related deferred financing costs. In 2016, we incurred an early redemption premium on the settlement of the 2018 Bonds Payable of $17.9 million, and write-offs of deferred financing costs in connection with other early repayments. We expect future gains or losses on early extinguishments of debt to vary with financing activities.
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. Future income or loss from unconsolidated joint ventures will vary as a result of future investing activities and leasing at the properties held in 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. 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. We expect future gains on sales of real estate assets will vary with disposition activity.
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 early extinguishment of debt in the prior year ($25.8 million), partially offset by lost income from sold properties ($38.4 million). See the "Supplemental Performance Measures" section below for our same-store results compared with the prior year. We expect future earnings to vary as a result of leasing activity at our existing properties and investing activities.
Comparison of the Year Ended December 31, 2016 Versus the Year Ended December 31, 2015
Rental income was $366.2 million for 2016, which represents a decrease from $436.0 million for 2015. The decrease is primarily due to current-year and prior-year dispositions ($53.0 million); transferring the Market Square Buildings to a joint venture in the fourth quarter of 2015 ($30.9 million); and vacancy at our 222 East 41st Street property for a portion of 2016 ($7.4 million) while the building was being prepared for NYU's Langone Medical lease to commence, partially offset by additional rental income from the acquisition of the 229 West 43rd Street Building in August 2015 ($19.9 million).
Tenant reimbursements and property operating costs were $69.8 million and $155.0 million, respectively, for 2016, which represents an increase from $99.7 million and $188.1 million, respectively, for 2015. The decrease in property operating costs is due to dispositions ($23.4 million) and the transfer of the Market Square Buildings to a joint venture ($16.4 million), partially offset by

additional property operating costs from the acquisition of the 229 West 43rd Street Building ($6.6 million). The proportional decrease in tenant reimbursements is also due to dispositions ($17.3 million) and the transfer of the Market Square Buildings to a joint venture ($9.4 million), partially offset by additional tenant reimbursements from the acquisition of the 229 West 43rd Street Building ($2.9 million).
Hotel income, net of hotel operating costs, was $4.0 million for 2016, which represents a decrease as compared with $4.7 million for 2015, due to additional group bookings and meetings at the hotel.
Asset and property management fee income was $2.1 million for 2016, which represents an increase as compared with $0.6 million for 2015. We began earning such fees in October 2015, upon the formation of the Market Square Joint Venture.
Other property income was $12.8 million for 2016, which represents an increase as compared with $5.4 million for 2015, primarily due to an early termination at our 222 East 41st Street property ($6.8 million).
Asset and property management fees were $1.4 million for 2016, which represents a decrease as compared with $1.8 million for 2015, primarily due to transferring Market Square to a joint venture in the fourth quarter of 2015.
Depreciation was $108.5 million for 2016, which represents a decrease as compared with $131.5 million for 2015, primarily due to dispositions ($16.3 million) and transferring Market Square to a joint venture ($11.6 million), partially offset by additional depreciation from the acquisition of 229 West 43rd Street in August 2015 ($5.4 million).
Amortization was $56.8 million for 2016, which represents a decrease as compared with $87.1 million for 2015. The decrease is primarily due to dispositions ($16.1 million); intangibles written off related to the expiration or termination of leases ($9.8 million); and transferring Market Square to a joint venture ($5.9 million); partially offset by additional amortization from the acquisition of 229 West 43rd Street in August 2015 ($2.6 million).
General and administrative expenses corporate was $33.9 million for 2016, which represents an increase from $29.7 million for 2015. The increase is due to costs incurred to develop our regional management and investment platform ($2.9 million), and additional vesting under our stock-based incentive compensation plan ($1.0 million).
We incurred acquisition expenses of $3.7 million for 2015 in connection with acquiring three properties in January 2015 and the 229 West 43rd Street Building in New York in August 2015. See Note 3, Real Estate Transactions, to the accompanying financial statements for additional details. We adopted Accounting Standards Update 2017-01, Clarifying the Definition of a Business, in the fourth quarter of 2017. (See Note 2, Summary of Significant Accounting Policies, of the accompanying consolidated financial statements.) As a result, we capitalized acquisition costs related to fourth quarter 2017 acquisitions and do not anticipate incurring future expenses related to acquisitions of properties.
Interest expense was $67.6 million for 2016, which represents a decrease as compared with $85.3 million for 2015, primarily due to transferring the Market Square mortgage note to a joint venture ($13.6 million) and repaying mortgage loans ($5.4 million), partially offset by the 2025 Bonds Payable outstanding for the entire year ($3.0 million).
Interest and other income was stable at $7.3 million for 2016 and 2015.
We recognized a loss on interest rate swaps that do not qualify for hedge accounting treatment of approximately $1.1 million for 2015, primarily due to the settlement of the swap related to a $450 million term loan, which was replaced with other unsecured borrowings in July 2015.
We recognized a loss on early extinguishment of debt of $19.0 million and $3.1 million in 2016 and 2015, respectively. In 2016, we incurred an early redemption premium on the settlement of the 2018 Bonds Payable of $17.9 million, and write-offs of deferred financing costs in connection with other early repayments. In 2015, we incurred a prepayment premium of $2.1 million related to the early repayment of the 215 Diehl Building mortgage note, approximately two years prior to its maturity and write-offs of deferred financing costs in connection with other early repayments.
We recognized a loss from unconsolidated joint ventures of $7.6 million for 2016, which represents an increase as compared with a loss of $1.1 million for 2015. The Market Square Joint Venture was formed on October 28, 2015. Since inception, real estate operating income from Market Square has been reduced by interest incurred on the property's $325 million mortgage note, and Market Square experienced reduced occupancy levels throughout 2016 due to lease expirations.
We recognized gains on sales of real estate assets of $72.3 million in 2016, as a result of selling six properties in separate transactions for an aggregate of $660.5 million, exclusive of transaction costs. We recognized gains on sales of real estate assets of $23.9 million in 2015, as a result of selling 12 properties for an aggregate of $498.3 million, exclusive of transaction costs, and the sale

of a 49% interest in Market Square for a gross sales price of $120.0 million. See Note 3, Real Estate Transactions, of the accompanying financial statements, for additional details of these dispositions.
Net income was $84.3 million, or $0.68 per basic and diluted share, for 2016, which represents an increase from $44.6 million, or $0.36 per basic and diluted share, for 2015. The increase is due to additional year-over-year gains on sales of real estate ($48.5 million) and a decrease in interest expense and other financing costs ($17.7 million), partially offset by additional year-over-year losses on early extinguishment of debt ($15.8 million), lower earnings due to property sales ($5.3 million), and increase in equity in loss of unconsolidated joint ventures ($6.4 million) due to reduced occupancy at Market Square. See "Supplemental Performance Measures" section below for our same-store results compared with the prior year period.
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, 2017, 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 14, Segment Information, to the accompanying consolidated financial statements.

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. San Francisco NOI is expected to decrease in the near term as a result of the sale of an additional 22.5% interest in each of these properties, as described in Note 3, Real Estate Transactions, of the accompanying consolidated financial statements.
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 is partially offset by decreased occupancy at 80 M Street and Market Square earlier in the current year. Over the near term, Washington, D.C. NOI is expected to increase as a result of recent leasing activity at 80 M Street and Market Square and recognizing a full period for our interest in 1800 M Street.
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 because it principally adjusts for the effects of GAAP depreciation and amortization of real estate assets, which assumes that the value of real estate diminishes predictably 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-related depreciation and amortization, and 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 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, 2016. NOI and Same Store NOI are calculated as follows for the years ended December 31, 2017 and 2016 (in thousands):

The slight decline in Same Store NOI is due to a temporary decline in occupancy at 650 California Street in San Francisco and at 315 Park Avenue South in New York. Anticipated lease expirations at 650 California Street and at 315 Park Avenue South allowed us to roll below-market leases up to market rates with recent leasing activities. As a result, future Same Store NOI is expected to increase at these properties and across the portfolio. The slight decline in Same Store NOI from prior year is also impacted by a lease expiration at 263 Shuman Boulevard, which is in the process of being returned to the lender in settlement of the mortgage note.

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 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 25% 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
  
40-45 years
Building and site improvements
  
5-25 years
Tenant improvements
  
Shorter of economic life or lease term
Intangible lease assets
  
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 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. We have determined that there is no impairment in the carrying values of our real estate assets and related intangible assets for the year ended December 31, 2017.
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.
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, 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 rates:
Direct costs associated with obtaining a new tenant, 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 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 value associated with effective contractual rental rates that are above or below market rates. 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 cost over the remaining term of the respective ground leases.
Related-Party Transactions and Agreements
During 2017, 2016, and 2015, 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 & Contingencies, to the accompanying consolidated financial statements for further explanation. Examples of such commitments and contingencies include:
guaranty of debt of an unconsolidated joint venture of $11.2 million;
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:
On February 7, 2018, the board of directors declared dividends for the first quarter of 2018 in the amount of $0.20 per share, payable on March 15, 2018, to stockholders of record on March 1, 2018.
On February 1, 2018, Columbia Property Trust sold an additional 22.5% interest in University Circle and 333 Market Street to its joint venture partner, Allianz, as described in Note 3, Real Estate Transactions, to the accompanying consolidated financial statements.
On January 4, 2018, we paid an aggregate amount of $24.0 million in dividends for the fourth quarter of 2017 to shareholders of record on December 1, 2017.
ITEM 7A.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
As a result of our 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 moderate level of overall borrowings. However, we currently have a substantial amount of debt outstanding. The majority of our borrowings are in the form of effectively fixed-rate financings, which helps to insulate our portfolio from interest rate risk. 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 fluctuation of interest rates in future periods.
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, 2017 and 2016, the estimated fair value of our consolidated line of credit and notes payable and bonds was $1.7 billion and $1.4 billion, respectively.
