DOCUMENTS INCORPORATED BY REFERENCE

Portions of the Registrant’s definitive Proxy statement for the Annual Meeting of Stockholders are incorporated by reference into Part III, Items 10-14 of this Annual Report on Form 10-K.

Explanatory Note

This annual report combines the Annual Reports on Form 10-K (“Annual Report”) for the year ended December 31, 2017, of Healthcare Trust of America, Inc. (“HTA”), a Maryland corporation, and Healthcare Trust of America Holdings, LP (“HTALP”), a Delaware limited partnership. Unless otherwise indicated or unless the context requires otherwise, all references in this Annual Report to “we,” “us,” “our,” “the Company” or “our Company” refer to HTA and HTALP, collectively, and all references to “common stock” shall refer to the Class A common stock of HTA.

HTA operates as a real estate investment trust (“REIT”) and is the general partner of HTALP. As of December 31, 2017, HTA owned a 98.1% partnership interest in HTALP, and other limited partners, including some of HTA’s directors, executive officers and their affiliates, owned the remaining partnership interest (including the long-term incentive plan (“LTIP” Units) in HTALP. As the sole general partner of HTALP, HTA has the full, exclusive and complete responsibility for HTALP’s day-to-day management and control, including its compliance with the Securities and Exchange Commission (“SEC”) filing requirements.

We believe it is important to understand the few differences between HTA and HTALP in the context of how we operate as an integrated consolidated company. HTA operates as an umbrella partnership REIT structure in which HTALP and its subsidiaries hold substantially all of the assets. HTA’s only material asset is its ownership of partnership interests of HTALP. As a result, HTA does not conduct business itself, other than acting as the sole general partner of HTALP, issuing public equity from time to time and guaranteeing certain debts of HTALP. HTALP conducts the operations of the business and issues publicly-traded debt, but has no publicly-traded equity. Except for net proceeds from public equity issuances by HTA, which are generally contributed to HTALP in exchange for partnership units of HTALP, HTALP generates the capital required for the business through its operations and by direct or indirect incurrence of indebtedness or through the issuance of its partnership units (“OP Units”).

Noncontrolling interests, stockholders’ equity and partners’ capital are the primary areas of difference between the consolidated financial statements of HTA and HTALP. Limited partnership units in HTALP are accounted for as partners’ capital in HTALP’s consolidated balance sheets and as noncontrolling interest reflected within equity in HTA’s consolidated balance sheets. The differences between HTA’s stockholders’ equity and HTALP’s partners’ capital are due to the differences in the equity issued by HTA and HTALP, respectively.

We believe combining the Annual Reports of HTA and HTALP, including the notes to the consolidated financial statements, into this single Annual Report results in the following benefits:


•	enhances stockholders’ understanding of HTA and HTALP by enabling stockholders to view the business as a whole in the same manner that management views and operates the business;


•	eliminates duplicative disclosure and provides a more streamlined and readable presentation since a substantial portion of the disclosure in this Annual Report applies to both HTA and HTALP; and


•	creates time and cost efficiencies through the preparation of a single combined Annual Report instead of two separate Annual Reports.

In order to highlight the material differences between HTA and HTALP, this Annual Report includes sections that separately present and discuss areas that are materially different between HTA and HTALP, including:


•	the Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities in Item 5 of this Annual Report;


•	the Selected Financial Data in Item 6 of this Annual Report;


•	the Funds From Operations (“FFO”) and Normalized FFO in Item 7 of this Annual Report;


•	the Controls and Procedures in Item 9A of this Annual Report;


•	the consolidated financial Statements in Item 15 of this Annual Report;


•	certain accompanying notes to the consolidated financial statements, including Note 7 - Debt, Note 10 - Stockholders’ Equity and Partners’ Capital, Note 12 - Per Share Data of HTA, Note 13 - Per Unit Data of HTALP, Note 15 - Tax Treatment of Dividends of HTA, Note 17 - Selected Quarterly Financial Data of HTA and Note 18 - Selected Quarterly Financial Data of HTALP;


•	the Statement Regarding the Computation of Ratio of Earnings to Fixed Charges and Preferred Stock Dividends included as Exhibit 12.1 to this Annual Report; and


•	the Certifications of the Chief Executive Officer and the Chief Financial Officer included as Exhibits 31 and 32 to this Annual Report.

In the sections of this Annual Report that combine disclosure for HTA and HTALP, this Annual Report refers to actions or holdings as being actions or holdings of the Company. Although HTALP (directly or indirectly through one of its subsidiaries) is generally the entity that enters into contracts, holds assets and issues or incurs debt, management believes this presentation is appropriate for the reasons set forth above and because the business of the Company is a single integrated enterprise operated through HTALP.

PART I

Item 1. Business

BUSINESS OVERVIEW

HTA, a Maryland corporation, and HTALP, a Delaware limited partnership, were incorporated or formed, as applicable, on April 20, 2006.

HTA is a publicly-traded REIT and one of the leading owners and operators of medical office buildings (“MOBs”) in the United States (“U.S.”). We focus on owning and operating MOBs that serve the future of healthcare delivery and are located on health system campuses, near university medical centers, or in community core outpatient locations. We also focus on key markets that have attractive demographics and macro-economic trends and where we can utilize our institutional full-service property management, leasing and development services platform to generate strong tenant and health system relationships and operating cost efficiencies. Our primary objective is to enhance the value of our real estate assets through our dedicated asset and property management platform, which generates consistent revenue streams and manageable expenses. As a result of our core business strategy, we seek to generate stockholder value through consistent and growing dividends, which are attainable through sustainable cash flows.

We invest in MOBs that we believe are critical to the delivery of healthcare in a changing environment. Healthcare is one of the fastest growing segments of the U.S. economy, with an expected average growth rate of nearly 6% between 2017 and 2025. Overall U.S. spending is expected to increase to 19.9% of GDP by 2025 according to the U.S. Centers for Medicare & Medicaid Services. In addition, healthcare is experiencing the fastest employment growth in the U.S., a trend that is expected to continue over the next decade. These high levels of demand are primarily driven by an aging U.S. population and the long-term impact of an increasing number of insured individuals nationwide. This increase in demand, combined with advances in less invasive medical procedures, is driving many healthcare services to lower costs and to more convenient outpatient settings that are less reliant on hospital campuses. As a result, HTA believes that well-located MOBs should provide stable cash flows with relatively low vacancy risk, resulting in consistent long-term growth.

Since inception, the Company has invested $7.0 billion primarily in MOBs, development projects, land, and other healthcare real estate assets that are primarily located in 20 to 25 high quality markets that possess above average economic and socioeconomic drivers. Our portfolio consists of approximately 24.1 million square feet of gross leasable area (“GLA”) throughout the U.S. As of December 31, 2017, approximately 70% of our portfolio was located on the campuses of, or adjacent to, nationally and regionally recognized healthcare systems. We believe these key locations and affiliations create significant demand from healthcare related tenants for our properties. Further, our portfolio is primarily concentrated within major U.S. metropolitan statistical areas (“MSAs”) that we believe will provide above-average economic growth and socioeconomic benefits over the coming years. As of December 31, 2017, we had approximately 1 million square feet of GLA in each of our top ten markets and approximately 93% of our portfolio, based on GLA, is located in the top 75 MSAs, with Dallas, Houston, Boston, Tampa and Atlanta being our largest markets by investment.

Our principal executive office is located at 16435 North Scottsdale Road, Suite 320, Scottsdale, AZ 85254, and our telephone number is (480) 998-3478. We maintain a website at www.htareit.com where additional information about us can be accessed. The contents of the site are not incorporated by reference in, or otherwise a part of this filing. We make our periodic and current reports, as well as any amendments to such reports, available at www.htareit.com as soon as reasonably practicable after such materials are electronically filed with the SEC. These reports are also available in hard copy to any stockholder upon request by contacting our investor relations staff at the number above or via email at info@htareit.com.

We also issued or entered into new debt agreements totaling $2.5 billion, which included $900.0 million in senior unsecured notes, $286.0 million promissory note (the “Promissory Note”), and entered into an amended and restated $1.3 billion unsecured credit agreement (the “Unsecured Credit Agreement”) which increased the amount available under the unsecured revolving credit facility to $1.0 billion and extended the maturities of the unsecured revolving credit facility to June 30, 2022 and for the $300.0 million unsecured term loan until February 1, 2023. The interest rate on the unsecured revolving credit facility is adjusted LIBOR plus a margin ranging from 0.83% to 1.55% per annum based on HTA’s credit rating.

•

BUSINESS STRATEGIES

Corporate Strategies

Invest in and Maintain a Portfolio of Properties that are Valuable for the Future of Healthcare Delivery

The Company is focused on investing in and maintaining a real estate portfolio that consists of well-located MOBs that allow for the efficient delivery of healthcare over the long-term. To date, we have invested $7.0 billion to create one of the largest portfolios (based on GLA) of healthcare real estate that is focused on the MOB sector in the U.S. We look to allocate capital to properties that exhibit the following key attributes:

•

Located on the campuses of, or aligned with, nationally and regionally recognized healthcare systems in the U.S. We seek to invest in properties that have long-term value for healthcare providers, including those that benefit from their proximity to and/or affiliation with prominent healthcare systems. These healthcare systems typically possess high credit quality and are capable of investing capital into their campuses. We believe our affiliations with these health systems helps ensure long-term tenant demand. As of December 31, 2017, approximately 70% of our portfolio was located on the campuses of, or adjacent to, nationally and regionally recognized healthcare systems.

•

Located in core community outpatient locations. We seek to invest in properties that will have long-term value for healthcare providers, including those that are located in key outpatient medical hubs that are located in communities. These properties benefit from their proximity to attractive patient populations, maintain a mix of physician practices and specialties, and are convenient for patients and physicians alike. In addition, these properties and medical hubs can be centers for healthcare away from hospital campuses while benefiting from the advancement of healthcare technology, which allow for lower cost settings, more services and procedures to be performed away from hospitals, and the growing requirement for convenient healthcare. We believe these factors ensure long-term tenant demand. At December 31, 2017, approximately 30% of our portfolio was located in core community outpatient locations.

•

Attractive markets where we can maximize efficiencies through our asset management and leasing platform. We seek to own MOBs in markets with attractive demographics, economic growth and higher barriers to entry which support growing tenant demand. We have developed a strong presence across 20 to 25 key markets since our inception, with approximately 93% of our total GLA located in top 75 MSAs as of December 31, 2017. In addition, we have developed scale in these key markets, reaching approximately 1 million square feet of GLA in each of our top ten markets, and approximately 500,000 square feet of GLA in our top 16 markets. Our scale in markets has allowed us to create the largest, institutionally owned asset management platform which includes leasing, property management, building maintenance, construction, and development capabilities. In each of these markets, we have established a strong asset management, leasing and development services platform that has allowed us to develop valuable relationships with health systems, physician practices, universities and regional development firms that have led to investment and leasing opportunities. Our property management platform utilizes our scale to provide services to our properties at cost effective rates and with a focus on generating cost efficiencies and superior service for our tenants.

•

Occupied with limited near term leasing risks. We seek to invest in and maintain well-occupied properties that we believe are critical to the delivery of healthcare within that specific market. As of December 31, 2017, our portfolio was 91.8% leased. We believe this creates tenant demand that supports higher occupancy and drives strong, long-term tenant retention as hospitals and physicians are reluctant to move or relocate, as evidenced by our Same-Property portfolio tenant retention rate of 78% as of the year ended December 31, 2017.

•

Diversified and synergistic mix of tenants. Our primary focus is placed on ensuring an appropriate and diversified mix of tenants from different practice types, as well as complimentary practices that provide synergies within both individual buildings and the broader health system campuses. We actively invest in both multi-tenant properties, which generally have shorter-term leases on smaller spaces, and single-tenant properties, which generally have longer-term leases. The multi-tenant buildings provide for lower lease rollover risks in any particular year and typically allow rents to reset to current market rates that may be higher than the in-place rental rates. We believe single-tenant buildings provide steady long-term cash flow, but generally provide for more limited long-term growth.

•

Credit-worthy tenants. Our primary tenants are healthcare systems, academic medical centers and leading physician groups. These groups typically have strong and stable financial performance, which we believe helps ensure stability in our long-term rental income and tenant retention. As of December 31, 2017, 61% of our annual base rent was derived from credit-rated tenants, primarily health systems. A significant amount of our remaining rent comes from physician groups and medical healthcare system tenants that are credit-worthy based on our internal underwriting and due diligence, but do not have the size to benefit from a formal credit rating by a nationally recognized rating agency.

Internal Growth through Proactive In-House Property Management and Leasing

Our internal property management and leasing team operates approximately 22.4 million square feet of GLA, or 93%, of our total portfolio. This is a significant increase since our public listing on the New York Stock Exchange (“NYSE”) in 2012 when we managed approximately 8.8 million square feet, or 70%, of our GLA. We believe this direct asset management approach allows us to maximize our internal growth by improving occupancy, achieving operating efficiencies and creating long-term tenant relationships at our properties, resulting in optimized rental rates. Specific components of our overall asset management strategy include:


•	Maintaining regional offices in markets where we have a significant presence. HTA has local offices in 24 markets, including its corporate headquarters in Scottsdale, Arizona, primarily in our key markets across the U.S.


•	Creating local relationships with local healthcare providers, including national and regional healthcare systems, physicians and other providers.


•	Maintaining or increasing our average rental rates, actively leasing vacant space and reducing leasing concessions. These leasing results contributed to our 2.8% or more Same-Property Cash NOI growth each quarter during the year ended December 31, 2017.


•	Improving the quality of service provided to our tenants by being attentive to their needs, managing expenses and strategically investing capital to remain competitive within our markets. During the year ended December 31, 2017, we achieved tenant retention for the Same-Property portfolio of 78%.


•	Maintaining a portfolio of high-quality medical office buildings that we believe are critical to the delivery of healthcare now and in the future, while enhancing our reputation as a dedicated leading MOB owner and operator.


•	Utilizing local and regional economies of scale to focus on operating cost efficiencies for our properties and utilizing our building service operations to generate profits for shareholders while providing more efficient services.

Key Market Focused Strategy and Investments

We plan to grow externally through targeted investments and developments that improve the quality of our portfolio and are accretive to our cost of capital. To achieve this growth in competitive markets we seek:


•	Targeted property investments, generally located within our key markets. These transactions allow us to focus on the quality of individual properties and ensure they are accretive to our cost of capital. They also allow us to exhibit meaningful growth given our current mid-market size.


•	Long-term relationships with key industry participants. We will continue our emphasis on long-term relationship building as we have since inception. These relationships are cultivated by our senior management team, with key industry participants, including health systems as well as local and regional developers, which have traditionally provided us with valuable investment opportunities.


•	Local knowledge through our internal full-service operational platform. Our local personnel participate in local industry activities that can provide insightful information with respect to potential opportunities.

Actively Maintain Conservative Capital Structure

We have and continue to actively manage our balance sheet to maintain an attractive investment grade credit rating, to maintain conservative leverage and to preserve financing flexibility, which ultimately hedges inherent risk and provides us with attractive capital sources that allow us to take advantage of strategic external growth opportunities. In addition, we may also strategically dispose of properties that we believe no longer align with our strategic growth objectives in order to redeploy the capital generated by these dispositions into higher yielding MOBs that we believe have better longer-term growth prospects. The strength of our balance sheet is demonstrated by our investment grade credit ratings. To maintain our strong and conservative balance sheet, we:


•	Maintain a low leverage ratio. Our leverage ratio, measured by net debt (total debt less cash and cash equivalents) to total capitalization, was 29.9% as of December 31, 2017.


•	Continue to maintain a high level of liquidity. As of December 31, 2017, we had approximately $1.2 billion of liquidity, primarily consisting of $991.2 million available on our unsecured revolving credit facility and $100.4 million of cash and cash equivalents.


•	Utilize multiple capital sources, including public debt and equity, unsecured bank loans and secured property level debt.


•	Maintain well-laddered debt maturities, which extend through 2027 with no significant exposure in any one year.


•	As of December 31, 2017, the weighted average remaining term of our debt portfolio was 5.7 years.

HEALTHCARE INDUSTRY

Healthcare Sector Growth

We operate MOBs within the healthcare industry, which we believe are benefiting from several significant macroeconomic drivers, such as an aging population, millennials beginning to form families, and an increase in the insured population. These trends are driving growth in healthcare spending at a rate significantly faster than the broader U.S. economy.

The U.S. population is experiencing significant aging of its population, as advancements in medical technology and changes in treatment methods enable people to live longer. This is expected to drive healthcare utilization higher as individuals consume more healthcare as they get older. Between 2016 and 2026, the U.S. population over 65 years of age is projected to increase by more than 32% and total over 19% of the U.S. population as the baby boomer generation enters retirement. Individuals of this age spend the highest amounts on healthcare, averaging approximately $6,000 per individual over the age of 65 according to a 2016 Consumer Expenditure Survey. This compares to healthcare expenditures of less than $1,200 per year for individuals under the age of 25. The older population group will increasingly require treatment and management of chronic and acute health ailments. We believe much of this increased care will take place in lower cost outpatient settings, which should continue to support MOB demand in the long term.

Table of Contents

In addition, the large millennial generation is just now starting to reach their thirties and form families. During this age period, healthcare expenditures double on average. As this large generation utilizes additional healthcare services, it is expected they will do so in more convenient outpatient settings.

The number of insured individuals in the U.S. continues to increase, as the population grows and as a result of the impact of U.S. government actions, including the Patient Protection and Affordable Care Act of 2010 (the “Affordable Care Act”). Since 1999, the number of individuals covered by healthcare insurance in the U.S. has increased over 20%. Although the current political administration has sought to unsuccessfully repeal the Affordable Care Act, Medicaid expansion remains in place with some states seeking to expand coverage. Thus far, the removal of the individual mandate in the Tax Cuts and Jobs Act (the “TCJA”) has seen limited noticeable impact.

Table of Contents

As a result of these factors, the healthcare sector is one of the fastest growing sectors of the U.S. economy and is growing faster than GDP. According to the latest data from 2017, Americans spent nearly $3.3 trillion, or 17.9% of total GDP, on healthcare expenditures in 2016, an increase of 4.3% over the previous year. The U.S. Centers for Medicare & Medicaid Services project that total healthcare expenditures will reach approximately $5.6 trillion by 2025. Healthcare expenditures are projected to grow an average of 5.6% annually through 2025 and account for 19.9% of GDP by 2025. This growth in healthcare expenditures reflects the increasing demand for healthcare. It is also driving demand for cost effective healthcare which generally takes place in outpatient settings such as MOBs.

Employment in the healthcare industry has steadily increased for at least 20 years despite three recessions. Healthcare-related jobs are among the fastest growing occupations, projected to increase by 18% between 2016 and 2026, significantly higher than the general U.S. employment growth projection of 7%, according to the Bureau of Labor Statistics. Additionally, the Bureau of Labor Statistics projects ten out of the top twenty occupations with the highest growth for workers will be in the healthcare sector. We expect the increased growth in the healthcare industry will correspond with a growth in demand for MOBs and other facilities that serve the healthcare industry.

Medical Office Building Supply and Demand

We believe that healthcare real estate, specifically MOBs, and its rents and valuations are less susceptible to changes in the general economy than general commercial real estate due to macroeconomic trends supporting the healthcare sector and the defensive nature of healthcare expenditures during economic downturns. For this reason, we believe MOB investments provide more consistent rental revenue streams, higher occupancies and tenant retention that could potentially translate into a more stable return to investors compared to other types of real estate investments which may be more susceptible to higher vacancies and unreliable rental revenue streams. We also believe that demand for MOBs will increase due to a number of MOB specific factors, including:


•	The MOB sector is highly fragmented with approximately 30% of the MOBs owned by public REITs and private equity firms. There is vast room for growth for both public and private firms to expand within the industry given the lack of institutional ownership compared to other real estate sectors.

•	Evolution in the healthcare industry resulting in more efficient and less invasive procedures that have traditionally been performed in hospitals, such as surgery, that have moved to outpatient facilities as a result of shifting consumer preferences, limited space in hospitals and lower costs.

•

An increase in medical office visits due to the overall rise in healthcare utilization which in turn has driven hiring within the healthcare sector. Additionally, the rate of employment growth in physicians’ offices and outpatient care facilities has outpaced employment growth in hospitals during the past decade, further supporting the trend of increased utilization of healthcare services outside of the hospital. This trend is forecast to continue, with the number of healthcare providers, particularly nurses, physicians, and technical specialists, growing significantly faster than the U.S. average.

•

High credit quality of physician tenants. In recent years, MOB tenants have increasingly consisted of larger hospital and physician groups. These groups utilize their size and expertise to obtain high rates of reimbursement and share overhead operating expenses which creates significant rent coverage, or an ability to pay rent. We believe these larger groups are generally credit-worthy and provide stability and long-term value for MOBs.


•	Construction of MOBs has been relatively constrained over the last five years, with high cost barriers to development in markets in which we invest.

PORTFOLIO OF PROPERTIES

As of December 31, 2017, our portfolio consisted of approximately 24.1 million square feet of GLA, with a leased rate of 91.8% (includes leases which have been executed, but which have not yet commenced).

Our properties were primarily located on the campuses of, or aligned with, nationally and regionally recognized healthcare systems in the U.S. These properties include leading health systems, such as Baylor Scott & White Health, Highmark-Allegheny Health Network, Community Health Systems, Greenville Health System and Ascension Health. The Company is the largest owner of on-campus or adjacent MOBs in the country, with approximately 16.9 million square feet of GLA, or 70%, of our portfolio located in these locations. The remaining 30% are located in core community outpatient locations where healthcare is increasingly being delivered.

COMPETITION

We compete with many other real estate investment entities, including financial institutions, pension funds, real estate developers, other REITs, other public and private real estate companies, and private real estate investors for the acquisition of MOBs and other facilities that serve the healthcare industry. During the acquisition process, we compete with others who may have a competitive advantage over us at this time in terms of size, capitalization, local knowledge of the marketplace and extended contacts throughout the region. Any combination of these factors may result in an increased purchase price for properties or other real estate related assets of interest to us, which may reduce the number of opportunities available to us that meet our investment criteria. If the number of opportunities that meet our investment criteria are limited, our ability to increase stockholder value may be adversely impacted.

We face competition in leasing available MOBs and other facilities that serve the healthcare industry to prospective tenants. As a result, we may have to provide rent concessions, incur charges for tenant improvements, offer other inducements, or we may be unable to timely lease vacant space in our properties, all of which may have an adverse impact on our results of operations. At the time we elect to dispose of our properties, we will also be in competition with sellers of similar properties to locate suitable purchase opportunities.

We believe our focus on MOBs, our experience and expertise, and our ongoing relationships with healthcare providers provide us with a competitive advantage. We have established an asset identification and acquisition network with healthcare providers and local developers which provides for the early identification of and access to acquisition opportunities. In addition, we believe this broad network allows us to effectively lease available space, retain our tenants, and maintain and improve our assets.

GOVERNMENT REGULATIONS

Healthcare-Related Regulations

Overview. The healthcare industry is heavily regulated by federal, state and local governmental agencies. Our tenants generally are subject to laws and regulations covering, among other things, licensure, certification for participation in government programs, fraud and abuse, relationships with physicians and other referral sources, and reimbursement. Changes in these laws and regulations could negatively affect the ability of our tenants to satisfy their contractual obligations, including making lease payments to us.

Healthcare Legislation. In March 2010, President Obama signed the Affordable Care Act into law. The Affordable Care Act, along with other healthcare reform efforts, has resulted in comprehensive healthcare reform in the U.S. through a phased approach, which began in 2010 and will conclude in 2018. The laws are intended to reduce the number of individuals in the U.S. without health insurance and significantly change the means by which healthcare is organized, delivered and reimbursed. The Affordable Care Act expanded reporting requirements and responsibilities related to facility ownership and management, patient safety, quality of care, and certain financial transactions, including payments by the pharmaceutical and medical industry to doctors and teaching hospitals. In the ordinary course of their businesses, our tenants may be regularly subjected to inquiries, investigations and audits by federal and state agencies that oversee these laws and regulations. If they do not comply with the additional reporting requirements and responsibilities, our tenants’ ability to participate in federal healthcare programs may be adversely affected. Moreover, there may be other aspects of the comprehensive healthcare reform legislation for which regulations have not yet been adopted, which, depending on how they are implemented, could adversely affect our tenants and their ability to meet their lease obligations to us.

The Affordable Care Act has faced numerous judicial, legislative and executive challenges. Although there continue to be judicial challenges to the Affordable Care Act, the Supreme Court has thus far upheld the Affordable Care Act, including, most recently, in their June 25, 2015 ruling on King v. Burwell. However, President Trump and Congressional, Republicans promised they would seek the repeal of the Affordable Care Act. On January 20, 2017, newly-sworn-in President Trump issued an executive order aimed at seeking the prompt repeal of the Affordable Care Act, and directed the heads of all executive departments and agencies to minimize the economic and regulatory burdens of the Affordable Care Act to the maximum extent permitted by law. In addition, there have been and continue to be numerous Congressional attempts to amend and repeal the Affordable Care Act. On December 22, 2017, President Trump signed the TCJA, which amends certain provisions of the Affordable Care Act including the elimination of the individual insurance mandate. We cannot predict whether any future attempts to amend or repeal the Affordable Care Act will be successful. The future of the Affordable Care Act is uncertain and any changes to existing laws and regulations, including the Affordable Care Act’s repeal, modification or replacement, could have a long-term financial impact on the delivery of and payment for healthcare. Both our tenants and us may be adversely affected by the law or its repeal, modification or replacement.

Reimbursement Programs. Sources of revenue for our tenants may include the federal Medicare program, Tricare, state Medicaid programs, private insurance carriers, health maintenance organizations, preferred provider arrangements and self-insured employers, among others. Medicare, Tricare and Medicaid programs, as well as numerous private insurance and managed care plans, generally require participating providers to accept government-determined reimbursement levels as payment in full for services rendered, without regard to facility charges. Changes in the reimbursement rate or methods of payment from third-party payors, including Medicare and Medicaid, could result in a substantial reduction in our tenants’ revenues.

In previous years, Medicare’s physician fee-for-service reimbursements were subject to a significant, automatic reduction in rates. Congress repeatedly enacted temporary legislation postponing the implementation of these physician rate cuts. In April 2015, the Medicare Access and CHIP Reauthorization Act of 2015, enacted rules that establishes physician reimbursement rates that allow for steady increases in rates over the near future.

Despite this “doc-fix” legislation, we cannot predict whether future Congressional proposals will seek to reduce physician reimbursements. Efforts by other such payors to reduce healthcare costs will likely continue, which may result in reductions or slower growth in reimbursement for certain services provided by some of our tenants. Further, revenue realizable under third-party payor agreements can change after examination and retroactive adjustment by payors during the claims settlement processes or as a result of post-payment audits. Payors may disallow requests for reimbursement based on determinations that certain costs are not reimbursable or reasonable, because additional documentation is necessary or because certain services were not covered or were not medically necessary.

Table of Contents

Amendments to or repeal of the Affordable Care Act and regulatory changes could impose further limitations on government and private payments to healthcare providers. The Affordable Care Act expanded Medicaid coverage to all individuals under age 65 with incomes up to 133% of the federal poverty level. While the federal government agreed to pay the Medicaid expansion costs for newly eligible beneficiaries from 2014 through 2016, the federal government’s portion began declining in 2017. Further, the U.S. Supreme Court held in 2012 that states could not be required to expand their Medicaid programs, which has resulted in some states deciding not to expand their Medicaid programs. More recently, the Trump administration has enacted, or is considering enacting, measures designed to reduce Medicaid expenditures. In some other cases, states have enacted or are considering enacting measures designed to reduce their Medicaid expenditures and to make changes to private healthcare insurance. Efforts to reduce costs will likely continue, which may result in reduced or slower growth in reimbursement for certain services provided by our tenants. In addition, the failure of any of our tenants to comply with various laws and regulations could jeopardize their ability to continue participating in Medicare, Tricare, Medicaid and other government sponsored payment programs. The financial impact on our tenants’ failure to comply with such laws and regulations could restrict their ability to make rent payments to us.

Various laws and Center for Medicare and Medicaid Services (“CMS”) initiatives and rules are also reducing or changing medical provider compensation and reimbursement. Recent changes include, among others:


•	Section 603 of the Bipartisan Budget Act of 2015, which eliminates certain facility fee reimbursements for outpatient centers that are located further than 250 yards from the main hospital campus. Existing health system facilities will continue to receive these facility fee reimbursements, but new facilities will not, resulting in minimal impact to our existing tenants’ operations.

•

Alternative payment models and payment reforms that compensate medical providers by quality of care and other criteria over quantity of care. The Health Care Payment Learning and Action Network is a network which is seeking to implement these reforms and CMS has various rules, such as the Merit-Based Incentive Payment System and Alternative Payment Models, which are changing how it compensates medical providers.


•	Proposed and finalized CMS rules which impact payments for specific types of services such as the “Lower Extremity Joint Replacement” and adjust reimbursement rates for specific types of healthcare facilities.

These new laws, initiatives and CMS rules reflect an ongoing effort to reduce healthcare costs and reimburse medical providers based on criteria other than fee-for-service. Although their impact is difficult to predict, these laws, initiatives and CMS rules may adversely impact medical providers’ reimbursement and our tenants’ ability to make rent payments to us.

Fraud and Abuse Laws. There are various federal and state laws prohibiting fraudulent and abusive business practices by healthcare providers who participate in, receive payments from, or are in a position to make referrals in connection with, government-sponsored healthcare programs, including the Medicare and Medicaid programs. Additionally, the Affordable Care Act includes program integrity provisions that both create new authorities and expand existing authorities for federal and state governments to address fraud, waste and abuse in federal healthcare programs. Our lease arrangements with certain tenants may also be subject to these fraud and abuse laws. These laws include, among others:


•	the Federal Anti-Kickback Statute, which prohibits, among other things, the offer, payment, solicitation or receipt of any form of remuneration in return for, or to induce, the referral or recommendation for the ordering of any item or service reimbursed by a federal healthcare program, including Medicare or Medicaid;

•

the Federal Physician Self-Referral Prohibition, commonly referred to as the “Stark Law,” which: (1) requires hospital landlords of facilities with financial relationships to charge a fair market value rent that does not take into account the volume or value of referrals and subject to specific exceptions; and (2) restricts physicians from making referrals for specifically designated health services for which payment may be made under Medicare and Medicaid programs to an entity with which the physician, or an immediate family member, has a financial relationship;


•	the False Claims Act, which prohibits any person from knowingly presenting or causing to be presented false or fraudulent claims for payment to the federal government, including claims paid by the Medicare and Medicaid programs;


•	the Civil Monetary Penalties Law, which authorizes the U.S. Department of Health and Human Services to impose monetary penalties for certain fraudulent acts and regulatory violations and to exclude violators from participating in federal healthcare programs;


•	the Health Insurance Portability and Accountability Act, as amended by the Health Information Technology for Economic and Clinical Health Act of the American Recovery and Reinvestment Act of 2009, which protects the privacy and security of personal health information; and


•	State laws which prohibit kickbacks, self-referrals and false claims, and are generally applicable to commercial and state payors.

Table of Contents

In the ordinary course of their business, our tenants may be subject to inquiries, investigations and audits by federal and state agencies that oversee applicable laws and regulations. Private enforcement of healthcare fraud has also increased, due in large part to amendments to the civil False Claims Act that were designed to encourage private individuals to sue on behalf of the government. These whistleblower suits, known as qui tam suits, may be filed by almost anyone, including present and former employees or patients. In addition to the False Claims Act, there may be civil litigation between private parties which seek damages for violations of federal and state laws. These types of actions may result in monetary penalties, punitive sanctions, damage assessments, imprisonment, increased governmental oversight, denial of Medicare and Medicaid payments and/or exclusion from the Medicare and Medicaid programs. Investigation by a federal or state governmental body for violation of fraud and abuse laws, imposition of any of these penalties upon one of our tenants, and civil litigation could jeopardize that tenant’s ability to operate or to make rent payments to us.

Healthcare Licensure and Certification. Some of our medical properties and our tenants may require a license, multiple licenses, a certificate of need (“CON”), or other certification to operate. Failure to obtain a license, CON, other certification, or loss of a required license, CON, or some other certification would prevent a facility from operating in the manner intended by the tenant. This event could adversely affect our tenants’ ability to make rent payments to us. State and local laws also may regulate plant expansion, including the addition of new beds or services or acquisition of medical equipment and the construction of healthcare-related facilities, by requiring a CON or other similar approval. State CON laws are not uniform throughout the U.S. and are subject to change. We cannot predict the impact of state CON laws on our facilities or the operations of our tenants.

Real Estate Ownership-Related Regulations

Many laws and governmental regulations are applicable to our properties and changes in these laws and regulations, or their interpretation by agencies and the courts, occur frequently. For example:

Costs of Compliance with the Americans with Disabilities Act. Under the Americans with Disabilities Act of 1990, as amended (the “ADA”), all places of public accommodation are required to comply with federal requirements related to access and use by disabled persons. Although we believe that we are in substantial compliance with present requirements of the ADA, none of our properties have been audited and we have only conducted investigations of a few of our properties to determine compliance. We may incur additional costs in connection with compliance with the ADA. Additional federal, state and local laws also may require modifications to our properties or restrict our ability to renovate our properties. We cannot predict the cost of compliance with the ADA or other legislation. We may incur substantial costs to comply with the ADA or any other legislation.

Costs of Government Environmental Regulation and Private Litigation. Environmental laws and regulations hold us liable for the costs of removal or remediation of certain hazardous or toxic substances which may be on our properties. These laws could impose liability on us without regard to whether we are responsible for the presence or release of the hazardous materials. Government investigations and remediation actions may cause substantial costs and the presence of hazardous substances on a property could result in personal injury or similar claims by private plaintiffs. Various laws also impose liability on persons who arrange for the disposal or treatment of hazardous or toxic substances and such persons oftentimes must incur the cost of removal or remediation of hazardous substances at the disposal or treatment facility. These laws often impose liability whether or not the person arranging for the disposal ever owned or operated the disposal facility. As the owner and operator of our properties, we may be deemed to have arranged for the disposal or treatment of hazardous or toxic substances.

Use of Hazardous Substances by Some of Our Tenants. Some of our tenants routinely handle hazardous substances and wastes on our properties as part of their routine operations. Environmental laws and regulations subject these tenants, and potentially us, to liability resulting from such activities. Our leases require our tenants to comply with these environmental laws and regulations and to indemnify us for any related liabilities. We are unaware of any material noncompliance, liability or claim relating to hazardous or toxic substances or petroleum products in connection with any of our properties.

Other Federal, State and Local Regulations. 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 various requirements, we may incur governmental fines or private damage awards. While we believe that our properties are currently in material compliance with all of these regulatory requirements, we do not know whether existing requirements will change or whether future requirements will require us to make significant unanticipated expenditures that will adversely affect our ability to make distributions to our stockholders. We believe, based in part on engineering reports which are generally obtained by us at the time we acquire the properties, that all of our properties comply in all material respects with current regulations. However, if we were required to make significant expenditures under applicable regulations, our financial condition, results of operations, cash flow, ability to satisfy our debt service obligations and to pay distributions to our stockholders could be adversely affected.

EMPLOYEES

As of December 31, 2017, we had approximately 270 employees, of which less than 1% are subject to a collective bargaining agreement.

TAX MATTERS

We filed an election with our 2007 federal income tax return to be taxed as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”). We believe we have satisfied the requirements to qualify as a REIT for all tax years starting in 2007 and we intend to maintain our qualification as a REIT in the future. As a qualified REIT, with limited exceptions, we are generally not subject to federal and certain state income tax on net income that we currently distribute to stockholders. We expect to continue to make distributions sufficient to avoid income tax.

While we believe that we are organized and qualified as a REIT and we intend to operate in a manner that will allow us to continue to qualify as a REIT, there can be no assurance that we will be successful in this regard. Our qualification as a REIT depends upon our ability to meet, through our annual operating results, asset diversification, distribution levels and diversity of stock ownership and the various qualification tests imposed under the Code. If we fail to maintain our qualification as a REIT, corporate level income tax would apply to our taxable income at the current corporate tax rates. As a result, the amount available for distributions to stockholders would be reduced and we would no longer be required to make distributions. Failure to qualify as a REIT could also adversely affect our ability to make investments and raise capital.

Qualification as a REIT involves the application of highly technical and complex provisions of the Code for which there are limited judicial and administrative interpretations and involves the determination of a variety of factual matters and circumstances not entirely within our control.

Federal Income Tax Changes and Updates for Incorporation in Existing Registration Statements

The following discussion supplements and updates the disclosures under “Material U.S. Federal Income Tax Considerations” in the prospectus dated February 27, 2015 contained in our Registration Statement on Form S-3 filed with the SEC on February 27, 2015 (the “Prospectus”), and in our other registration statements into which this Annual Report is incorporated by reference.

Taxation of Our Company

As discussed in the Prospectus under “Material U.S. Federal Income Tax Considerations - Taxation of Our Company” and “Material U.S. Federal Income Tax Considerations - Investments in TRSs,” even if we qualify for taxation as a REIT, we will be subject to U.S. federal income tax in certain circumstances. Among those circumstances, we will be subject to a 100% tax on the amounts of any rents from real property, deductions, or excess interest received from a taxable REIT subsidiary (a “TRS”) that would be reduced under the Code, in order to clearly reflect the income of the TRS or to the extent that such interest payments are in excess of a rate that is commercially reasonable. Pursuant to the Protecting Americans from Tax Hikes Act of 2015, which was signed into law on December 18, 2015 (the “Act”) and effective for taxable years beginning after December 31, 2015, we will also be subject to a 100% tax on certain income (net of certain deductions) imputed to a TRS, as a result of redetermining or reallocating income among related or commonly controlled entities.

Qualification as a REIT

Income Tests

Gain from the Sale of Real Estate Assets. As discussed in the Prospectus under “Material U.S. Federal Income Tax Considerations - Qualification as a REIT - Income Tests,” we must satisfy two gross income requirements annually to maintain our qualification as a REIT. Qualifying income for purposes of the 95% gross income test described therein generally includes the items identified in the second bullet point under “Income Tests” however, effective for taxable years beginning after December 31, 2015, gain from the sale of “real estate assets” also includes gain from the sale of a debt instrument issued by a “publicly offered REIT” (i.e., a REIT that is required to file annual and periodic reports with the SEC under the Exchange Act) even if not secured by real property or an interest in real property. However, for purposes of the 75% income test, gain from the sale of a debt instrument issued by a publicly offered REIT would not be treated as qualifying income to the extent such debt instrument would not be a real estate asset but for the inclusion of debt instruments of publicly offered REITs in the meaning of real estate assets effective for taxable years beginning after December 31, 2015, as described below under “Asset Tests - Qualifying Assets.”

Table of Contents

Investments in Certain Debt Instruments. As discussed in the Prospectus under “Material U.S. Federal Income Tax Considerations - Investments in Certain Debt Instruments,” interest income generally constitutes qualifying mortgage interest for purposes of the 75% gross income test to the extent that the obligation upon which such interest is paid is secured by a mortgage on real property or an interest in real property. Except as provided in the following sentence, if we receive interest income with respect to a mortgage loan that is secured by both real and other property, and the highest principal amount of the loan outstanding during a taxable year exceeds the fair market value of the real property on the date that we committed to acquire the loan, or agreed to modify the loan in a manner that is treated as an acquisition of a new loan for U.S. federal income tax purposes, the interest income will be apportioned between the real property and the other collateral, and our income from the arrangement will qualify for purposes of the 75% gross income requirement only to the extent that the interest is allocable to the real property. For taxable years beginning after December 31, 2015, in the case of mortgage loans secured by both real and personal property, if the fair market value of such personal property does not exceed 15% of the total fair market value of all property securing the loan, then the personal property securing the loan will be treated as real property for purposes of determining whether the mortgage is qualifying under the 75% asset requirement and the interest income from such loan qualifies for purposes of the 75% gross income requirement.

Hedging Transactions. The discussion in the Prospectus under “Material U.S. Federal Income Tax Considerations - Qualification as a REIT - Income Tests - Hedging transactions” is replaced in its entirety with the following:

We may enter into hedging transactions with respect to one or more of our assets or liabilities. Hedging transactions could take a variety of forms, including interest rate swaps or cap agreements, options, futures contracts, forward rate agreements or similar financial instruments. Except to the extent as may be provided by future Treasury Regulations, any income from a hedging transaction which is clearly identified as such before the close of the day on which it was acquired, originated or entered into, including gain from the disposition or termination of such a transaction, will not constitute gross income for purposes of the 95% and 75% gross income tests, provided that the hedging transaction is entered into (i) in the normal course of our business primarily to manage risk of interest rate or price changes or currency fluctuations with respect to indebtedness incurred or to be incurred by us to acquire or carry real estate assets or (ii) primarily to manage the risk of currency fluctuations with respect to any item of income or gain that would be qualifying income under the 75% or 95% income tests (or any property which generates such income or gain).

Effective for taxable years beginning after December 31, 2015, if we have entered into a qualifying hedge described above with respect to certain indebtedness or property, or the Original Hedge, and a portion of the hedged indebtedness is extinguished or property hedged is disposed of and in connection with such extinguishment or disposition we enter into one or more clearly identified hedging transactions that would, in general, hedge the Original Hedge, or the Counteracting Hedge, income from the applicable Original Hedge and income from the Counteracting Hedge (including gain from the disposition of the Original Hedge or the Counteracting Hedge) will not be treated as gross income for purposes of the 95% and 75% gross income tests to the extent that the Counteracting Hedge hedges the Original Hedge.

To the extent we enter into other types of hedging transactions, the income from those transactions is likely to be treated as nonqualifying income for purposes of both the 75% and 95% gross income tests. We intend to structure and monitor our hedging transactions so that such transactions do not jeopardize our ability to qualify as a REIT.

Asset Tests

Qualifying Assets. As discussed in the Prospectus under “Material U.S. Federal Income Tax Considerations - Qualification as a REIT - Asset Tests,” to maintain our qualification as a REIT, we also must satisfy several asset tests at the end of each quarter of each taxable year. Under the first test described in the Prospectus, at least 75% of the value of our total assets must consist of the qualifying assets described in the Prospectus. In addition to those items described in the Prospectus, pursuant to the Act, effective for taxable years beginning after December 31, 2015, qualifying assets for purposes of the 75% asset test includes: (i) personal property leased in connection with real property to the extent that rents attributable to such personal property are treated as “rents from real property” for purposes of the 75% gross income test and (ii) debt instruments issued by “publicly offered REITs.” However, the Act further provides an additional test, effective for taxable years beginning after December 31, 2015, under which not more than 25% of the value of our total assets may be represented by debt instruments issued by publicly offered REITs to the extent those debt instruments would not be real estate assets but for the inclusion of debt instruments of publicly offered REITs in the meaning of real estate assets effective for taxable years beginning after December 31, 2015, as described above.

Securities of TRSs. In addition, the fourth test described in the Prospectus under “Material U.S. Federal Income Tax Considerations - Qualification as a REIT - Asset Tests,” that securities of TRSs cannot represent more than 25% of our total assets, has been modified by the Act such that, for taxable years beginning after December 31, 2017, securities of TRSs cannot represent more than 20% of our total assets.

Table of Contents

Annual Distribution Requirements

Elective Cash/Stock Dividends. On August 11, 2017, the Internal Revenue Service (“IRS”) issued Revenue Procedure 2017-45 authorizing elective cash/stock dividends to be made by publicly offered REITs (i.e., REITs that are required to file annual and periodic reports with the U.S. Securities and Exchange Commission under the Securities Exchange Act of 1934). Pursuant to Revenue Procedure 2017-45, effective for distributions declared on or after August 11, 2017, the IRS will treat the distribution of stock pursuant to an elective cash/stock dividend as a distribution of property under Section 301 of the Code (i.e., a dividend), as long as at least 20% of the total dividend is available in cash and certain other parameters detailed in the Revenue Procedure are satisfied.

Preferential Dividends. The Prospectus discusses our distribution requirements under the caption “Material U.S. Federal Income Tax Considerations - Qualification as a REIT - Annual Distribution Requirements.” The prohibition against “preferential dividends” described in that section is applicable for distributions in taxable years beginning on or before December 31, 2014. For all subsequent taxable years, so long as we continue to be a “publicly offered REIT,” the preferential dividend rule will not apply.

Interest Expense Deductions

The TCJA, signed into law in December 2017 generally imposes certain limitations on the ability of taxpayers top deduct net business interest expenses for federal income tax purposes beginning on or after January 1, 2018. However, the TCJA provides an election whereby certain taxpayers engaged in a real estate trade or business, generally including for this purpose a REIT, may elect for this limitation not to apply. However, taxpayers that make this election generally are not eligible for certain depreciation methodologies. We may make this election for applicable tax years, in which case the above limitations on interest expense deductions generally would not apply to us.

In addition, the above described limitations on net business interest expense deductions generally would be determined at the entity-level. As a result, the ability of our TRSs to deduct business interest expense for tax years beginning on or after January 1, 2018 may be subject to limitations under the TCJA even if we make such an election.

Net Operating Losses

The TCJA also generally restricts the ability of taxpayers to utilize net operating losses to no more than 80% their taxable income and precludes them from carry-back net operating losses to prior tax years for tax years beginning on or after January 1, 2018.

Taxation of U.S. Stockholders

Distributions. The Prospectus discusses the taxation of U.S. stockholders on distributions with respect to “qualified dividend income” and “capital gain dividends” under the caption “Material U.S. Federal Income Tax Considerations - Taxation of U.S. Stockholders - Distributions.” In addition to the discussion contained therein, effective for distributions in taxable years beginning after December 31, 2015, the aggregate amount of dividends that we may designate as “capital gain dividends” or “qualified dividend income” with respect to any taxable year may not exceed the dividends paid by us with respect to such year, including dividends that are paid in the following year that are treated as paid with respect to such year.

Furthermore, pursuant to the TCJA, dividends received from REITs that are treated as “qualified REIT dividends” received by certain individuals, trusts and estates generally qualify for a 20% deduction, subject to certain limitations, for taxable years beginning after December 31, 2017 and before January 1, 2026. For this purpose, a “qualified REIT dividend” generally includes any dividend from a REIT received during a taxable year that is not (i) a “capital gain dividend” or (ii) “qualified dividend income.”

Taxation of Non-U.S. Stockholders

Distributions

FIRPTA Ownership Exemptions. The Prospectus discusses the Foreign Investment in Real Property Tax Act of 1980 (“FIRPTA”) exemption with respect to non-U.S. stockholders that own no more than 5% of our Class A common stock during the specified period on distributions attributable to gain from sales or exchanges by us of “United States real property interests” under the caption “Material U.S. Federal Income Tax Considerations - Taxation of Non-U.S. Stockholders - Distributions.” This FIRPTA exemption limit on distributions on publicly-traded REIT stock has been increased from ownership of more than 5% of such stock to ownership of more than 10% of such stock for distributions on or after December 18, 2015. In addition, the Prospectus notes that we may be required to withhold 10% of any distribution that exceeds our current and accumulated earnings and profits. This 10% withholding requirement was increased to 15% under the Act for distributions after February 16, 2016. Consequently, although we intend to withhold at a rate of 30% on the entire amount of any relevant distribution, to the extent we do not do so, we may withhold at a rate of 15% on any portion of a distribution not subject to withholding at a rate of 30%.

Table of Contents

FIRPTA Withholding. The Prospectus discusses that we generally must withhold 35% of any distributions attributable to gain from the sale or exchange of “United States real property interests” described in the Prospectus under the caption “Material U.S. Federal Income Tax Considerations - Taxation of Non-U.S. Stockholders - Distributions” (defined as “35% FIRPTA Withholding”). Pursuant to the TCJA, for taxable years beginning on or after January 1, 2018, this rate is 21% and references to “35% FIRPTA Withholding” should be replaced for such periods with “21% FIRPTA Withholding.” Moreover, the Prospectus notes that it is not entirely clear to what extent we are required to withhold on distributions to non-U.S. stockholders that are not treated as ordinary income and are not attributable to the disposition of the United States real property interest. The Prospectus further notes that unless the law is clarified to the contrary, we will generally withhold and remit to the IRS 35% of any distribution to a non-U.S. stockholder that is designated as a capital gain dividend (or, if greater, 35% of a distribution that could have been designated as a capital gain dividend). Pursuant to the TCJA, for taxable years beginning on or after January 1, 2018, references to 35% are replaced with 21%.

Distributions to Qualified Shareholders. In addition, the discussion in the Prospectus is further supplemented by inserting the paragraphs below at the end of the subsection with the heading “Material U.S. Federal Income Tax Considerations - Taxation of Non-U.S. Stockholders - Distributions.”

Distributions to Qualified Shareholders. Subject to the exception discussed below, for purposes of any distribution on or after December 18, 2015 to a “qualified shareholder” who holds REIT stock directly (or indirectly through one or more partnerships), such REIT stock will not be treated as a “United States real property interest” and, thus, such distribution should not be subject to special rules under FIRPTA. However, a “qualified shareholder” with one or more “applicable investors” (i.e., persons other than “qualified shareholders” who hold interests in the “qualified shareholder” (other than interests solely as a creditor), and hold (or are deemed to hold under attribution rules) more than 10% of the stock of such REIT (whether or not by reason of the investor’s ownership in the “qualified shareholder”)), as well as such applicable investors, may be subject to FIRPTA rules.

A “qualified shareholder” is a foreign person that (i) either is eligible for the benefits of a comprehensive income tax treaty with the United States which includes an exchange of information program and whose principal class of interests is listed and regularly traded on one or more recognized stock exchanges (as defined in such comprehensive income tax treaty), or is a foreign partnership that is created or organized under foreign law as a limited partnership in a jurisdiction that has an agreement for the exchange of information with respect to taxes with the United States and has a class of limited partnership units that is regularly traded on the NYSE or NASDAQ markets representing greater than 50% of the value of all the partnership units, (ii) is a qualified collective investment vehicle (defined below), and (iii) maintains records on the identity of each person who, at any time during the foreign person’s taxable year, is the direct owner of 5% or more of the class of interests or units (as applicable) described in (i), above.

A qualified collective investment vehicle is a foreign person that (i) would be eligible for a reduced rate of withholding with respect to ordinary dividends paid by a REIT under the comprehensive income tax treaty described above, even if such entity holds more than 10% of the stock of such REIT, (ii) is publicly traded, is treated as a partnership under the Code, is a withholding foreign partnership, and would be treated as a “United States real property holding corporation” during a specified period if it were a domestic corporation, or (iii) is designated as such by the Secretary of the Treasury and is either (a) fiscally transparent within the meaning of Section 894 of the Code, or (b) required to include dividends in its gross income, but is entitled to a deduction for distributions to its investors.

Qualified Foreign Pension Funds. With respect to any distribution after December 18, 2015 to a “qualified foreign pension fund” or an entity all of the interests of which are held by a “qualified foreign pension fund” who holds REIT stock directly (or indirectly through one or more partnerships), such distribution will not be subject to special rules under FIRPTA.

A qualified foreign pension fund is any trust, corporation, or other organization or arrangement (i) which is created or organized under the law of a country other than the U.S., (ii) which is established to provide retirement or pension benefits to participants or beneficiaries that are current or former employees (or persons designated by such employees) of one or more employers in consideration for services rendered, (iii) which does not have a single participant or beneficiary with a right to more than 5% of its assets or income, (iv) which is subject to government regulation and provides annual information reporting about its beneficiaries to the relevant tax authorities in the country in which it is established or operates, and (v) with respect to which, under the laws of the country in which it is established or operates, (A) contributions to such trust, corporation, organization or arrangement that would otherwise be subject to tax under such laws are deductible or excluded from the gross income of such entity or taxed at a reduced rate, or (B) taxation of any investment income of such trust, corporation, organization or arrangement is deferred or such income is taxed at a reduced rate.

The provisions of the Act relating to qualified shareholders, applicable investors, and qualified foreign pension funds are complex. Stockholders should consult their tax advisors with respect to the impact of the Act on them.

Table of Contents

Dispositions

In addition, the discussion in the Prospectus is further supplemented by inserting the paragraphs below at the end of the subsection with the heading “Material U.S. Federal Income Tax Considerations - Taxation of Non-U.S. Stockholders - Dispositions.”

Qualified Shareholders and Qualified Pension Funds. After December 18, 2015, a sale of our Class A common stock by:


•	a “qualified shareholder” without one or more applicable investors or


•	a “qualified pension fund”

who holds such Class A common stock directly (or indirectly through one or more partnerships) will not be subject to U.S. federal income taxation under FIRPTA. A “qualified shareholder” with one or more applicable investors may be subject to such rules.

The provisions of the Act relating to qualified shareholders, applicable investors and qualified foreign pension funds are complex. Stockholders should consult their tax advisors with respect to the impact of the Act on them.

FATCA Withholding

The discussion in the Prospectus under “Material U.S. Federal Income Tax Considerations - FATCA Withholding” is replaced in its entirety with the following:

Sections 1471 through 1474 of the Code and the Treasury regulations promulgated thereunder (commonly referred to as “FATCA”) generally impose a 30% withholding tax on U.S. source dividends and, beginning January 1, 2019, gross proceeds from the sale or other disposition of stock or property that is capable of producing U.S. source dividends paid to (i) a foreign financial institution (as defined in Section 1471(d)(4) of the Code) unless such foreign financial institution agrees, pursuant to an agreement with the U.S. Treasury Department or otherwise, to collect and disclose certain information regarding its direct and indirect U.S. owners (which, for this purpose, can include certain debt and equity holders of such foreign financial institution as well as the direct and indirect owners of financial accounts maintained by such institution) and satisfies certain other requirements, and (ii) certain other non-U.S. entities unless such entities provide the payor with information regarding certain direct and indirect U.S. owners of the entity, or certify that they have no such U.S. owners, and comply with certain other requirements. Withholding under FATCA is imposed on payments to foreign financial institutions and other applicable payees whether they receive such payments in the capacity of an intermediary or for their own account. Certain countries have entered into, and other countries are expected to enter into, agreements with the United States to facilitate the type of information reporting required under FATCA. While the existence of such agreements will not eliminate the risk that payments in respect of our Class A common stock will be subject to the withholding described above, these agreements are expected to reduce the risk of the withholding for investors in (or indirectly holding our Class A common stock through financial institutions in) those countries. Each non-U.S. stockholder and any U.S. stockholder holding our Class A common stock through a foreign financial institution is urged to consult its tax advisor about the possible impact of these rules on their investment in our Class A common stock, and the entities through which they hold our Class A common stock, including, without limitation, the process and deadlines for meeting the applicable requirements to prevent the imposition of this 30% withholding of tax under FATCA.

Tax Cuts and Jobs Act

As discussed above, the TCJA was enacted on December 22, 2017. The TCJA made a number of fundamental changes to the U.S. federal income taxation of individuals, corporations and estates. Moreover, the rules relating to REITS are constantly under review by the IRS and the U.S Treasury Department, which may result in new or significant changes to existing Treasury Regulations, statutes or interpretations thereof.

In addition to the statutory changes enacted by the TCJA referenced above, the TCJA generally reduced the U.S. federal income tax rate applicable to corporations from 35% to 21% for taxable years beginning after December 31, 2017. As a result, the relative competitive advantage a REIT may enjoy to the extent the REIT is not typically subject to corporate income tax may be diminished. On the other hand, as described above, the TCJA generally reduced the maximum U.S. federal income tax rate on ordinary REIT dividends received by non-corporate taxpayers from 39.6% to 37% and generally permits non-corporate taxpayers to deduct 20% of qualified REIT dividends. As further described above, the tax law changes enacted by the TCJA could significantly impact both business and financial results, as well as the tax consequences of an investment in our common stock.

Prospective investors are urged to consult their tax advisors regarding the effect of the TCJA and any other potential changes to United States federal tax law on an investment in our common stock.

EXECUTIVE OFFICERS OF THE REGISTRANT

The information regarding our executive officers included in Part III, Item 10 of this Annual Report is incorporated herein by reference.

Item 1A. Risk Factors

Risks Related to Our Business

We are dependent on investments in the healthcare property sector, making our profitability more vulnerable to a downturn or slowdown in that specific sector than if we were investing in multiple industries.

We concentrate our investments in the healthcare property sector. As a result, we are subject to risks inherent to investments in a single industry. A downturn or slowdown in the healthcare property sector would have a greater adverse impact on our business than if we had investments in multiple industries. Specifically, a downturn in the healthcare property sector could negatively impact the ability of our tenants to make lease payments to us as well as our ability to maintain rental and occupancy rates, which could adversely affect our business, financial condition and results of operations, the market price of our common stock and our ability to make distributions to our stockholders.

Our ability to make future acquisitions may be impeded, or the cost of these acquisitions may be increased, due to a variety of factors, including competition for the acquisition of MOBs and other facilities that serve the healthcare industry.

At any given time, we may be pursuing property acquisitions or have properties subject to letters of intent, but we cannot assure you that we will acquire any such properties because the letters of intent are non-binding and potential transaction opportunities are subject to a variety of factors, including: (i) the willingness of the current property owner to proceed with a potential transaction with us; (ii) our completion of due diligence that is satisfactory to us and our receipt of internal approvals; (iii) the negotiation and execution of mutually acceptable binding purchase agreements; and (iv) the satisfaction of closing conditions, including our receipt of third-party consents and approvals. We also compete with many other entities engaged in real estate investment activities for the acquisition of MOBs and other facilities that serve the healthcare industry, including national, regional and local operators, acquirers and developers of healthcare properties. The competition for the acquisition of healthcare properties may significantly increase the prices we must pay for MOBs and other facilities that serve the healthcare industry or other real estate related assets we seek to acquire. This competition may also effectively limit the number of suitable investment opportunities offered to us or the number of properties that we are able to acquire, and may increase the bargaining power of property owners seeking to sell to us, making it more difficult for us to acquire new properties on attractive terms. The potential sellers of our acquisition targets may find our competitors to be more attractive purchasers because they may have greater resources, may be willing to pay more to acquire the properties or may have a more compatible operating philosophy. In particular, larger healthcare REITs may enjoy significant competitive advantages over us that result from, among other things, a lower cost of capital and enhanced operating efficiencies. Moreover, our competitors generally may be able to accept more risk with respect to their acquisitions than we can prudently manage or are willing to accept. In addition, the number of our competitors and the amount of funds competing for suitable investment properties may increase, which could result in increased demand for these properties and, therefore, increased prices to acquire them. Because of an increased interest in single-property acquisitions among tax-motivated individual purchasers, we may pay higher prices for the purchase of single properties in comparison with the purchase of multi-property portfolios. If we pay higher prices for MOBs and other facilities that serve the healthcare industry, or otherwise incur significant costs and divert management attention in connection with the evaluation and negotiation of potential acquisitions, including potential transactions that we are subsequently unable or elect not to complete, our business, financial condition and results of operations, the market price of our common stock and our ability to make distributions to our stockholders may be adversely affected.

Table of Contents

We may not be able to maintain or expand our relationships with hospitals, healthcare system and developers, which may impede our ability to identify and complete acquisitions directly from hospitals, healthcare systems and developers, and may otherwise adversely affect our growth, business, financial condition and results of operations, the market price of our common stock and our ability to make distributions to our stockholders.

The success of our business depends to a large extent on our past, current and future relationships with hospitals, healthcare systems and developers, including our ability to acquire properties directly from hospitals, healthcare systems and developers. We invest a significant amount of time to develop and maintain these relationships, and these relationships have helped us secure acquisition opportunities. Facilities that are acquired directly from hospitals, healthcare systems and developers are typically more attractive to us as a purchaser because of the absence of a formal competitive marketing process, which could lead to higher prices. If any of our relationships with hospitals, healthcare systems and developers deteriorates, or if a conflict of interest or a non-compete arrangement prevents us from expanding these relationships, our professional reputation within the industry could be damaged and we may not be able to secure attractive acquisition opportunities directly from hospitals, healthcare systems and developers in the future, which could adversely affect our ability to locate and acquire facilities at attractive prices.

Our results of operations, our ability to pay distributions to our stockholders and our ability to dispose of our investments are subject to general economic conditions affecting the commercial real estate and credit markets.

Our business is sensitive to national, regional and local economic conditions, as well as the commercial real estate and credit markets. For example, a financial disruption or credit crisis could negatively impact the value of commercial real estate assets, contributing to a general slowdown in our industry. A slow economic recovery could cause a reduction in the overall volume of transactions, number of sales and leasing activities of the type that we previously experienced. We are unable to predict future changes in national, regional or local economic, demographic or real estate market conditions.

Adverse economic conditions in the commercial real estate and credit markets may result in:


•	defaults by tenants at our properties due to bankruptcy, lack of liquidity or operational failures;


•	increases in vacancy rates due to tenant defaults, the expiration or termination of tenant leases and reduced demand for MOBs and other facilities that serve the healthcare industry;


•	increases in tenant inducements, tenant improvement expenditures, rent concessions or reduced rental rates, especially to maintain or increase occupancies at our properties;


•	reduced values of our properties, thereby limiting our ability to dispose of our assets at attractive prices or obtain debt financing secured by our properties on satisfactory terms, as well as reducing the availability of unsecured loans;

•

the value and liquidity of our short-term investments and cash deposits being reduced as a result of a deterioration of the financial condition of the institutions that hold our cash deposits or the institutions or assets in which we have made short-term investments, the dislocation of the markets for our short-term investments, increased volatility in market rates for such investment and other factors;


•	one or more lenders under our credit facilities refusing to fund their financing commitments to us and, in such event, we are unable to replace the financing commitments of any such lender or lenders on favorable terms, or at all;


•	a recession or rise in interest rates, which could make it more difficult for us to lease our properties or dispose of our properties or make alternative interest-bearing and other investments more attractive, thereby lowering the relative value of our existing real estate investments;


•	one or more counterparties to our interest rate swaps default on their obligations to us, thereby increasing the risk that we may not realize the benefits of these instruments;


•	increases in the supply of competing properties or decreases in the demand for our properties, which may impact our ability to maintain or increase occupancy levels and rents at our properties or to dispose of our investments; and


•	increased insurance premiums, real estate taxes or energy costs or other expenses, which may reduce funds available for distribution to our stockholders or, to the extent such increases are passed through to our tenants, may lead to tenant defaults, tenant turnover, or make it difficult for us to increase rents to tenants on lease turnover which may limit our ability to increase our returns.

Our business, financial condition and results of operations, the market price of our common stock and our ability to pay distributions to our stockholders may be adversely affected to the extent an economic slowdown or downturn is prolonged or becomes more severe.

Table of Contents

Our growth depends on external sources of capital that are outside of our control, which may affect our ability to seize strategic opportunities, satisfy debt obligations and make distributions to our stockholders.

In order to qualify as a REIT, we must distribute to our stockholders, on an annual basis, at least 90% of our REIT taxable income, determined without regard to the deduction for dividends paid and excluding net capital gains. Because of these distribution requirements, we may not be able to fund future capital needs, including any necessary acquisition financings, from operating cash flow. Consequently, we may need to rely on third-party sources to fund our capital needs, meet our debt service obligations, make distributions to our stockholders or make future investments necessary to implement our business strategy. We may not be able to obtain financing on favorable terms, in the time period we desire, or at all. Our access to third-party sources of capital depends, in part, on a number of factors, including: general market conditions; the market’s perception of our growth potential; our current debt levels; our current and expected future earnings; our cash flow and cash distributions; and the market price per share of our common stock. If we cannot obtain capital from third-party sources, we may not be able to acquire properties when strategic opportunities exist, satisfy our principal and interest obligations to our lenders or make the cash distributions to our stockholders necessary to maintain our qualification as a REIT.

Our success depends to a significant degree upon the continued contributions of certain key personnel, each of whom would be difficult to replace. If we were to lose the benefit of the experience, efforts and abilities of one or more of these individuals, our operating results could suffer.

Our ability to achieve our investment objectives and to pay distributions is dependent upon the performance of our Board of Directors, our executive officers and our other employees, in the identification and acquisition of investments, the determination and finalization of our financing arrangements, the asset management of our investments, and the operation of our day-to-day activities. Our stockholders will have no opportunity to evaluate the terms of transactions or other economic or financial data concerning our investments that are not described in this Annual Report or other periodic filings with the SEC. We rely primarily on the management ability of our executive officers and the governance by the members of our Board of Directors, each of whom would be difficult to replace. We do not have any key-person life insurance on our executive officers. Although we have entered into employment agreements with each of our executive officers, these employment agreements contain various termination and resignation rights. If we were to lose the benefit of the experience, efforts and abilities of these executives, without satisfactory replacements, our operating results could suffer. In addition, if any member of our Board of Directors were to resign, we would lose the benefit of such director’s governance, experience and familiarity with us and the sector within which we operate. As a result of the foregoing, we may be unable to achieve our investment objectives or to pay distributions to our stockholders.

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

We rely on information technology networks and systems, including the Internet, to process, transmit and store electronic information, and to manage or support a variety of business processes, including financial transactions and records, personal identifying information, and tenant and lease data. Although we have taken steps to protect the security of our information systems and the data maintained in those systems, it is possible that our safety and security measures will not be able to prevent the systems’ improper functioning or damage, or the improper access or disclosure of personally identifiable information such as in the event of cyber-attacks. Security breaches, including physical or electronic break-ins, computer viruses, attacks by hackers and similar breaches, can create system disruptions, shutdowns or unauthorized disclosure of confidential information. Any failure to maintain proper function, security and availability of our information systems could interrupt our operations, damage our reputation, subject us to liability claims or regulatory penalties and could have an adverse effect on our business, results of operations and financial condition.

Risks Related to our Organizational Structure

We may structure acquisitions of property in exchange for limited partnership units of our operating partnership on terms that could limit our liquidity or our flexibility.

We may continue to acquire properties by issuing limited partnership units of our operating partnership, HTALP, in exchange for a property owner contributing property to us. If we continue to enter into such transactions in order to induce the contributors of such properties to accept units of our operating partnership rather than cash in exchange for their properties, it may be necessary for us to provide additional incentives. For instance, our operating partnership’s limited partnership agreement provides that any holder of units may exchange limited partnership units on a one-for-one basis for, at our option, cash equal to the value of an equivalent number of shares of common stock. We may, however, enter into additional contractual arrangements with contributors of property under which we would agree to repurchase a contributor’s units for shares of our common stock or cash, at the option of the contributor, at set times. If the contributor required us to repurchase units for cash pursuant to such a provision, it would limit our liquidity and, thus, our ability to use cash to make other investments, satisfy other obligations or make distributions to stockholders. Moreover, if we were required to repurchase units for cash at a time when we did not have sufficient cash to fund the repurchase, we might be required to sell one or more of our properties to raise funds to satisfy this obligation. Furthermore, we might agree that if distributions the contributor received as a limited partner in our operating partnership did not provide the contributor with an established return level, then upon redemption of the contributor’s units we would pay the contributor an additional amount necessary to achieve that return. Such a provision could further negatively impact our liquidity and flexibility. Finally, in order to allow a contributor of a property to defer taxable gain on the contribution of property to our operating partnership, we might agree not to sell a contributed property for a defined period of time or until the contributor exchanged the contributor’s units for cash or shares. Such an agreement would prevent us from selling those properties, even if market conditions would allow such a sale to be favorable to us.

Our Board of Directors may change our investment objectives and major strategies and take other actions without seeking stockholder approval.

Our Board of Directors determines our investment objectives and major strategies, including our strategies regarding investments, financing, growth, debt capitalization, REIT qualification and distributions. Our Board of Directors may amend or revise these and other strategies without a vote of the stockholders. Under our charter and Maryland law, our stockholders will have a right to vote only on the following matters:


•	the election or removal of directors;


•	our dissolution;


•	certain mergers, consolidations, conversions, statutory share exchanges and sales or other dispositions of all or substantially all of our assets; and

•

amendments of our charter, except that our Board of Directors may amend our charter without stockholder approval to change our name or the name or other designation, or the par value of any class or series of our stock and the aggregate par value of our stock, increase or decrease the aggregate number of our shares of stock or the number of our shares of any class or series that we have the authority to issue or effect certain reverse stock splits.

As a result, our stockholders will not have a right to approve most actions taken by our Board of Directors.

Certain provisions of Maryland law could delay, defer or prevent a change of control transaction.

Certain provisions of the Maryland General Corporation Law (“MGCL”) applicable to us may have the effect of inhibiting or deterring a third party from making a proposal to acquire us or of delaying or preventing a change of control under circumstances that otherwise could provide our stockholders with the opportunity to realize a premium over the then-prevailing market price of such shares, including:


•	provisions of the MGCL that permit our Board of Directors, without our stockholders’ approval and regardless of what is currently provided in our charter or bylaws, to implement certain takeover defenses, including adopting a classified board;

•

“business combination” provisions that, subject to limitations, prohibit certain business combinations, asset transfers and equity security issuances or reclassifications between us and an “interested stockholder” (defined generally as any person who beneficially owns, directly or indirectly, 10% or more of the voting power of our outstanding voting stock or an affiliate or associate of ours who, at any time within the two-year period immediately prior to the date in question, was the beneficial owner, directly or indirectly, of 10% or more of our then outstanding stock) or an affiliate of an interested stockholder for five years after the most recent date on which the stockholder becomes an interested stockholder, and thereafter may impose supermajority voting requirements unless certain minimum price conditions are satisfied; and

Table of Contents

“control share” provisions that provide that holders of “control shares” of HTA (defined as shares which, when aggregated with other shares controlled by the stockholder, entitle the stockholder to exercise one of three increasing ranges of voting power in electing directors) acquired in a “control share acquisition” (defined as the direct or indirect acquisition of ownership or control of issued and outstanding “control shares”) have no voting rights except to the extent approved by our stockholders by the affirmative vote of at least two-thirds of all the votes entitled to be cast on the matter, excluding all interested shares.

In the case of the business combination provisions of the MGCL, our Board of Directors has adopted a resolution providing that any business combination between us and any other person is exempted from this statute, provided that such business combination is first approved by our Board. This resolution, however, may be altered or repealed in whole or in part at any time. In the case of the control share provisions of the MGCL, we have opted out of these provisions pursuant to a provision in our bylaws. We may, however, by amendment to our bylaws, opt in to the control share provisions of the MGCL. We may also choose to adopt a classified board or other takeover defenses in the future. Any such actions could deter a transaction that may otherwise be in the interest of our stockholders.

Risks Related to Investments in Real Estate and Other Real Estate Related Assets

We are dependent on the financial stability of our tenants.

Lease payment defaults by our tenants would cause us to lose the revenue associated with such leases. Although 61% of our annualized base rent was derived from tenants (or their parent companies) that have a credit rating, a tenants’ credit rating (or its’ parents credit rating) is no guarantee of a tenant’s ability to perform its lease obligations and a parent company may choose not to satisfy the obligations of a subsidiary that fails to perform its obligations. If the property is subject to a mortgage, a default by a significant tenant on its lease payments to us may result in a foreclosure on the property if we are unable to find an alternative source of revenue to meet mortgage payments. In the event of a tenant default, we may experience delays in enforcing our rights as a landlord and we may incur substantial costs in protecting our investment and re-leasing our property, and we may not be able to re-lease the property for the rent previously received, if at all. Lease terminations and expirations could also reduce the value of our properties.

We face potential adverse consequences of bankruptcy or insolvency by our tenants.

We are exposed to the risk that our tenants could become bankrupt or insolvent. This risk would be magnified to the extent that a tenant leased space from us in multiple facilities. The bankruptcy and insolvency laws afford certain rights to a party that has filed for bankruptcy or reorganization. For example, a debtor-tenant may reject its lease with us in a bankruptcy proceeding. In such a case, our claim against the debtor-tenant for unpaid and future rents would be limited by the statutory cap of the U.S. Bankruptcy Code. This statutory cap might be substantially less than the remaining rent actually owed to us under the lease, and it is quite likely that any claim we might have against the tenant for unpaid rent would not be paid in full. In addition, a debtor-tenant may assert in a bankruptcy proceeding that its lease should be re-characterized as a financing agreement. If such a claim is successful, our rights and remedies as a lender, compared to our rights and remedies as a landlord, would generally be more limited.

Our tenant base may not remain stable or could become more concentrated which could harm our operating results and financial condition.

Our tenant base may not remain stable or could become more concentrated among particular physicians and physician groups with varying practices and other medical service providers in the future. Subject to the terms of the applicable leases, our tenants could decide to leave our properties for numerous reasons, including, but not limited to, financial stress or changes in the tenant’s ownership or management. Our tenants service the healthcare industry and our tenant mix could become even more concentrated if a preponderance of our tenants practice in a particular medical field or are reliant upon a particular healthcare system. If any of our tenants become financially unstable, our operating results and prospects could suffer, particularly if our tenants become more concentrated.

Our MOBs, developments, redevelopments, and other facilities that serve the healthcare industry and our tenants may be subject to competition.

Our MOBs, developments, redevelopments, and other facilities that serve the healthcare industry often face competition from nearby hospitals, developers, and other MOBs that provide comparable services. Some of those competing facilities are owned by governmental agencies and supported by tax revenues, while others are owned by nonprofit corporations and may be supported to a large extent by endowments and charitable contributions. These types of financial support are not available to buildings we own or develop.

Table of Contents

Similarly, our tenants face competition from other medical practices in nearby hospitals and other medical facilities. Further, referral sources, including physicians and managed care organizations, may change their lists of hospitals or physicians to which they refer patients. Competition and loss of referrals could adversely affect our tenants’ ability to make rental payments, which could adversely affect our rental revenues. Any reduction in rental revenues resulting from the inability of our MOBs and other facilities that serve the healthcare industry and our tenants to compete successfully may have an adverse effect on our business, financial condition and results of operations, the market price of our common stock and our ability to make distributions to our stockholders.

The hospitals on whose campuses our MOBs are located and their affiliated healthcare systems could fail to remain competitive or financially viable, which could adversely impact their ability to attract physicians and physician groups to our MOBs and our other facilities that serve the healthcare industry.

Our MOB operations and other facilities that serve the healthcare industry depend on the viability of the hospitals on whose campuses our MOBs are located and their affiliated healthcare systems in order to attract physicians and other healthcare-related users. The viability of these hospitals, in turn, depends on factors such as the quality and mix of healthcare services provided, competition, demographic trends in the surrounding community, market position and growth potential, as well as the ability of the affiliated healthcare systems to provide economies of scale and access to capital. If a hospital whose campus is located on or near one of our MOBs is unable to meet its financial obligations, and if an affiliated healthcare system is unable to support that hospital, the hospital may not be able to compete successfully or could be forced to close or relocate, which could adversely impact its ability to attract physicians and other healthcare-related users. Because we rely on our proximity to and affiliations with these hospitals to create tenant demand for space in our MOBs, their inability to remain competitive or financially viable, or to attract physicians and physician groups, could adversely affect our MOB operations and have an adverse effect on us.

The unique nature of certain of our properties, including our senior healthcare properties, may make it difficult to lease or transfer our property or find replacement tenants, which could require us to spend considerable capital to adapt the property to an alternative use or otherwise negatively affect our performance.

Some of the properties we own or may seek to acquire are specialized medical facilities or otherwise designed or built for a particular tenant of a specific type of use known as a single use facility. For example, senior healthcare facilities present unique challenges with respect to leasing and transfer. Skilled nursing, assisted living and independent living facilities are typically highly customized and may not be easily modified to accommodate non-healthcare-related uses. The improvements generally required to conform a property to healthcare use, such as upgrading electrical, gas and plumbing infrastructure, are costly and oftentimes operator-specific. As a result, these property types may not be suitable for lease to traditional office tenants or other healthcare tenants with unique needs without significant expenditures or renovations. A new or replacement tenant may require different features in a property, depending on that tenant’s particular operations.

If we or our tenants terminate or do not renew the leases for our properties or our tenants lose their regulatory authority to operate such properties or default on their lease obligations to us for any reason, we may not be able to locate, or may incur additional costs to locate, suitable replacement tenants to lease the properties for their specialized uses. Alternatively, we may be required to spend substantial amounts to modify a property for a new tenant, or for multiple tenants with varying infrastructure requirements, before we are able to re-lease the space or we could otherwise incur re-leasing costs. Furthermore, because transfers of healthcare facilities may be subject to regulatory approvals not required for transfers of other types of property, there may be significant delays in transferring operations of senior healthcare facilities to successor operators. Any loss of revenues or additional capital expenditures required as a result may have an adverse effect on our business, financial condition and results of operations, the market price of our common stock and our ability to make distributions to our stockholders.

Table of Contents

Uninsured losses relating to real estate and lender requirements to obtain insurance may reduce stockholder returns.

There are types of losses relating to real estate, generally catastrophic in nature, such as losses due to wars, acts of terrorism, earthquakes, floods, hurricanes, pollution or environmental matters, for which we do not intend to obtain insurance unless we are required to do so by mortgage lenders. If any of our properties incurs a casualty loss that is not fully covered by insurance, the value of our assets will be reduced by any such uninsured loss. In addition, other than any reserves we may establish, we have no source of funding to repair or reconstruct any uninsured damaged property, and we cannot assure our stockholders that any such sources of funding will be available to us for such purposes in the future. Also, to the extent we must pay unexpectedly large amounts for uninsured losses, we could suffer reduced earnings that would result in less cash to be distributed to our stockholders. In cases where we are required by mortgage lenders to obtain casualty loss insurance for catastrophic events or terrorism, such insurance may not be available, or may not be available at a reasonable cost, which could inhibit our ability to finance or refinance our properties. Additionally, if we obtain such insurance, the costs associated with owning a property would increase and could have an adverse effect on the net income from the property and, thus, the cash available for distribution to our stockholders.

We may fail to successfully operate acquired properties.

Our ability to successfully operate any properties is subject to the following risks:


•	we may acquire properties that are not initially accretive to our results upon acquisition and we may not successfully manage and lease those properties to meet our expectations;


•	we may spend more than budgeted to make necessary improvements or renovations to acquired properties;


•	we may be unable to quickly and efficiently integrate new acquisitions, particularly acquisitions of portfolios of properties, into our existing operations and, as a result, our results of operations and financial condition could be adversely affected;


•	market conditions may result in higher than expected vacancy rates and lower than expected rental rates; and

•

we may acquire properties subject to liabilities, including contingent liabilities, and without any recourse, or with only limited recourse, with respect to unknown liabilities for the clean-up of undisclosed environmental contamination, claims by tenants or other persons dealing with former owners of the properties, liabilities, claims, and litigation, including indemnification obligations, whether or not incurred in the ordinary course of business, relating to periods prior to or following our acquisitions, claims for indemnification by general partners, directors, officers and others indemnified by the former owners of the properties, and liabilities for taxes relating to periods prior to our acquisitions.

If we are unable to successfully operate acquired properties, our financial condition, results of operations, the market price of our common stock, cash flow and ability to satisfy our principal and interest obligations and to make distributions to our stockholders could be adversely affected.

We may not be able to control our operating costs or our expenses may remain constant or increase, even if our revenue does not increase, which could cause our results of operations to be adversely affected.

Factors that may adversely affect our ability to control operating costs include the need to pay for insurance and other operating costs, including real estate taxes, which could increase over time, the need periodically to repair, renovate and re-let space, the cost of compliance with governmental regulation, including zoning and tax laws, the potential for liability under applicable laws, interest rate levels and the availability of financing. If our operating costs increase as a result of any of the foregoing factors, our results of operations may be adversely affected. The expenses of owning and operating MOBs and other facilities that serve the healthcare industry are not necessarily reduced when circumstances such as market factors and competition cause a reduction in income from the property. As a result, if our revenue declines, we may not be able to reduce our expenses accordingly. Certain costs associated with real estate investments may not be reduced even if a property is not fully occupied or other circumstances cause our revenues to decrease. If one or more of our properties is mortgaged and we are unable to meet the mortgage payments, the lender could foreclose on the mortgage and take possession of the properties, resulting in a further reduction in our net income.

Table of Contents

Increases in property taxes could adversely affect our cash flow.

Our properties are subject to real and personal property taxes that may increase as tax rates change and as the real properties are assessed or reassessed by taxing authorities. Some of our leases generally provide that the property taxes or increases therein are charged to the tenants as an expense related to the real properties that they occupy, while other leases provide that we are generally responsible for such taxes. We are also generally responsible for real property taxes related to any vacant space. In any case, as the owner of the properties, we are ultimately responsible for payment of the taxes to the applicable government authorities. If real property taxes increase, our tenants may be unable to make the required tax payments, ultimately requiring us to pay the taxes even if the tenant is obligated to do so under the terms of the lease. If we fail to pay any such taxes, the applicable taxing authority may place a lien on the real property and the real property may be subject to a tax sale.

Our ownership of certain MOB properties and other facilities are subject to ground leases or other similar agreements which limit our uses of these properties and may restrict our ability to sell or otherwise transfer such properties.

As of December 31, 2017, we held interests in MOB properties and other facilities that serve the healthcare industry through leasehold interests in the land on which the buildings are located and we may acquire additional properties in the future that are subject to ground leases or other similar agreements. As of December 31, 2017, these properties represented 38% of our total GLA. Many of our ground leases and other similar agreements limit our uses of these properties and may restrict our ability to sell or otherwise transfer such properties without the ground landlord’s consent, which may impair their value.

Our real estate development, redevelopment and construction platform is subject to risks that could adversely impact our results of operations.

A component of our current growth strategy is, when appropriate, to pursue accretive development and redevelopment projects. However, there are inherent risks associated with these development and redevelopment projects, including, but not limited to the following:


•	The development costs of a project may exceed budgeted amounts, causing the project to be not profitable or incur a loss;


•	We may encounter delays as a result of a variety of factors that are beyond our control, including natural disasters, material shortages, and regulatory requirements;


•	Time required to complete the construction of a project or to lease up the completed project may be greater than originally anticipated, thereby adversely affecting our cash flows and liquidity;


•	Lease rates and rents at newly developed or redeveloped properties may fluctuate based on factors beyond our control, including market and economic conditions as well as aforementioned budget overages;


•	We may be unable to obtain favorable financing terms to fund our development projects;


•	Financing arrangements may require certain milestones, covenants, and other contractual terms that may be violated if the performance of our development and redevelopment projects differs from our projected income; and


•	Demand from prospective tenants may be reduced due to competition from other developers.

Uncertain market conditions relating to the future disposition of properties or other real estate related assets could cause us to sell our properties or real estate assets on unfavorable terms or at a loss in the future.

We intend to hold our various real estate investments until such time as we determine that a sale or other disposition appears to be advantageous to achieve our investment objectives. Our Chief Executive Officer and our Board of Directors may exercise their discretion as to whether and when to sell a property and we will have no obligation to sell properties at any particular time. Our Board of Directors may also choose to effect a liquidity event in which we liquidate our investments in other real estate related assets. We generally intend to hold properties for an extended period of time and our mortgage investments until maturity, and we cannot predict with certainty the various market conditions affecting real estate investments that will exist at any particular time in the future. Because of the uncertainty of market conditions that may affect the future disposition of our properties, we may not be able to sell our properties at a profit in the future or at all, and we may incur prepayment penalties in the event we sell a property subject to a mortgage earlier than we otherwise had planned. Additionally, if we liquidate our mortgage investments prior to their maturity, we may be forced to sell those investments on unfavorable terms or at a loss. For instance, if we are required to liquidate mortgage loans at a time when prevailing interest rates are higher than the interest rates of such mortgage loans, we would likely sell such loans at a discount to their stated principal values. Any inability to sell a property or liquidation of a mortgage investment prior to maturity could adversely impact our business, financial condition and results of operation, the market price of our common stock and ability to pay distributions to our stockholders.

Table of Contents

The mortgage or other real estate-related loans in which we have in the past, and may in the future, invest may be impacted by unfavorable real estate market conditions and delays in liquidation, which could decrease their value.

If we make additional investments in real estate notes receivable, we will be at risk of loss on those investments, including losses as a result of borrower defaults on mortgage loans. These losses may be caused by many conditions beyond our control, including economic conditions affecting real estate values, tenant defaults and lease expirations, interest rate levels and the other economic and liability risks associated with real estate as described elsewhere under this heading. Furthermore, if there are borrower defaults under our mortgage loan investments, we may not be able to foreclose on or obtain a suitable remedy with respect to such investments. Specifically, we may not be able to repossess and sell the properties under our mortgage loans quickly, which could reduce the value of our investment. For example, an action to foreclose on a property securing a mortgage loan is regulated by state statutes and rules and is subject to many of the delays and expenses of lawsuits if the defendant raises defenses or counterclaims. In the event of a borrower default, these restrictions, among other things, may impede our ability to foreclose on or sell the mortgaged property or to obtain proceeds sufficient to repay all amounts due to us on the mortgage loan. Additionally, if we acquire property by foreclosure following a borrower default under our mortgage loan investments, we will have the economic and liability risks as the owner described above. Thus, we do not know whether the values of the property securing any of our investments in real estate related assets will remain at the levels existing on the dates we initially make the related investment. If the values of the underlying properties decline, our risk will increase and the value of our interests may decrease.

Lease rates under our long-term leases may be lower than fair market lease rates over time.

We have entered into and may in the future enter into long-term leases with tenants at certain of our properties. Certain of our long-term leases provide for rent to increase over time. However, if we do not accurately judge the potential for increases in market rental rates, we may set the terms of these long-term leases at levels such that even after contractual rental increases, the rent under our long-term leases is less than then-current market rental rates. Further, we may have no ability to terminate those leases or to adjust the rent to then-prevailing market rates. As a result, our income and distributions could be lower than if we did not enter into long-term leases.

Rents associated with new leases for properties in our portfolio may be less than expiring rents (lease roll-down) on existing leases, which may adversely affect our financial condition, results of operations and cash flow.

Our operating results depend upon our ability to maintain and increase rental rates at our properties while also maintaining or increasing occupancy. The rental rates for expiring leases may be higher than starting rental rates for new leases and we may also be required to offer greater rental concessions than we have historically. The rental rate spread between expiring leases and new leases may vary both from property to property and among different leased spaces within a single property. If we are unable to obtain sufficient rental rates across our portfolio, our business, financial condition and results of operation, the market price of our common stock and ability to pay distributions to our stockholders could be adversely affected.

Costs associated with complying with the Americans with Disabilities Act of 1990 may result in unanticipated expenses.

Under the ADA, all places of public accommodation are required to meet certain U.S. federal requirements related to access and use by disabled persons. A number of additional U.S. federal, state and local laws may also require modifications to our properties, or restrict certain further renovations of the properties, with respect to access thereto by disabled persons. Noncompliance with the ADA could result in the imposition of fines or an award of damages to private litigants and/or an order to correct any non-complying feature, which could result in substantial capital expenditures. We have not conducted an audit or investigation of all of our properties to determine our compliance and we cannot predict the ultimate cost of compliance with the ADA or other legislation. If one or more of our properties is not in compliance with the ADA or other related legislation, then we would be required to incur additional costs to bring the facility into compliance. If we incur substantial costs to comply with the ADA or other related legislation, our business, financial condition and results of operations, the market price of our common stock and ability to make distributions to our stockholders may be adversely affected.

Risks Related to the Healthcare Industry

New laws or regulations affecting the heavily regulated healthcare industry, changes to existing laws or regulations, loss of licensure or failure to obtain licensure could result in the inability of our tenants to make rent payments to us.

The healthcare industry is heavily regulated by federal, state and local governmental agencies. Our tenants generally are subject to laws and regulations covering, among other things, licensure, certification for participation in government programs, and relationships with physicians and other referral sources. Changes in these laws and regulations could negatively affect the ability of our tenants to make lease payments to us and our ability to make distributions to our stockholders.

Table of Contents

Many of our medical properties and our tenants may require a license or multiple licenses or a CON to operate. Failure to obtain a license or a CON or loss of a required license or a CON would prevent a facility from operating in the manner intended by the tenant. These events could adversely affect our tenants’ ability to make rent payments to us. State and local laws also may regulate expansion, including the addition of new beds or services or acquisition of medical equipment, and the construction of facilities that serve the healthcare industry, by requiring a CON or other similar approval. State CON laws are not uniform throughout the U.S. and are subject to change. We cannot predict the impact of state CON laws on our facilities or the operations of our tenants.

In limited circumstances, loss of state licensure or certification or closure of a facility could ultimately result in loss of authority to operate the facility and require new CON authorization to re-institute operations. As a result, a portion of the value of the facility may be reduced, which would adversely impact our business, financial condition and results of operations, the market price of our common stock and our ability to make distributions to our stockholders.

Comprehensive healthcare reform legislation could adversely affect our business, financial condition and results of operations, the market price of our common stock and our ability to pay distributions to stockholders.

In March 2010, President Obama signed the Affordable Care Act. The Affordable Care Act, along with other healthcare reform efforts has resulted in comprehensive healthcare reform in the U.S. through a phased approach, which began in 2010 and will conclude in 2018. It remains difficult to predict the impact of these laws on us due to their complexity, lack of implementing regulations or interpretive guidance, and the gradual implementation of the laws over a multi-year period. During the 2016 Presidential and Congressional campaigns, Republicans promised they would seek the repeal of the Affordable Care Act. On January 20, 2017, newly-sworn-in President Trump issued an executive order aimed at seeking the prompt repeal of the Affordable Care Act, and directed the heads of all executive departments and agencies to minimize the economic and regulatory burdens of the Affordable Care Act to the maximum extent permitted by law. In addition, there have been and continue to be numerous Congressional attempts to amend and repeal the law. We cannot predict whether any of these attempts to amend or repeal the law will be successful. The future of the Affordable Care Act is uncertain and any changes to existing laws and regulations, including the Affordable Care Act’s repeal, modification or replacement, could have a long-term financial impact on the delivery of and payment for healthcare. Both our tenants and us may be adversely affected by the law or its repeal, modification or replacement.

Reductions in reimbursement from third party payors, including Medicare and Medicaid, could adversely affect the profitability of our tenants and hinder their ability to make rent payments to us.

Sources of revenue for our tenants may include the federal Medicare program, state Medicaid programs, private insurance carriers, health maintenance organizations, preferred provider arrangements and self-insured employers, among others. Changes in the reimbursement rate or methods of payment from third-party payors, including Medicare and Medicaid, could impact the revenue of our tenants.

The healthcare industry also faces various challenges, including increased government and private payor pressure on healthcare providers to control or reduce costs. A focus on controlling costs could have an adverse effect on the financial condition of some or all of our tenants. The financial impact on our tenants could restrict their ability to make rent payments to us, which would have an adverse effect on our business, financial condition and results of operations and our ability to make distributions to our stockholders.

Government budget deficits could lead to a reduction in Medicaid and Medicare reimbursement, which could adversely affect the financial condition of our tenants.

Adverse U.S. economic conditions have negatively affected state budgets, which may put pressure on states to decrease reimbursement rates with the goal of decreasing state expenditures under state Medicaid programs. The need to control Medicaid expenditures may be exacerbated by the potential for increased enrollment in state Medicaid programs due to unemployment, declines in family incomes and eligibility expansions required by the recently enacted healthcare reform law. These potential reductions could be compounded by the potential for federal cost-cutting efforts that could lead to reductions in reimbursement rates under both the federal Medicare program and state Medicaid programs. Potential reductions in reimbursements under these programs could negatively impact the ability of our tenants and their ability to meet their obligations to us, which could, in turn, have an adverse effect on our business, financial condition and results of operations, the market price of our common stock and our ability to make distributions to our stockholders.

Table of Contents

Some tenants at our MOBs and our other facilities that serve the healthcare industry are subject to fraud and abuse laws, the violation of which by a tenant may jeopardize the tenant’s ability to make rent payments to us.

As described in the Item 1 - Business, there are various federal and state laws prohibiting fraudulent and abusive business practices by healthcare providers who participate in, receive payments from, or are in a position to make referrals in connection with, government-sponsored healthcare programs, including the Medicare and Medicaid programs. In the ordinary course of their business, our tenants may be subject to inquiries, investigations and audits by federal and state agencies as well as whistleblower suits under the False Claims Act from private individuals. An investigation by a federal or state governmental agency for violation of fraud and abuse laws, a whistleblower suit, or the imposition of criminal/civil penalties upon one of our tenants could jeopardize that tenant’s ability to operate or to make rent payments. In turn, this may have an adverse effect on our business, financial condition and results of operations and our ability to make distributions to our stockholders.

Risks Related to Debt Financing

We have and intend to incur indebtedness, which may increase our business risks, could hinder our ability to make distributions and could decrease the value of our Company.

As of December 31, 2017, we had fixed and variable rate debt of $2.8 billion outstanding. We intend to continue to finance a portion of the purchase price of our investments in real estate and other real estate related assets by borrowing funds. In addition, we may incur mortgage debt and pledge some or all of our real properties as security for that debt to obtain funds to acquire additional real properties or for working capital. We may also borrow funds to satisfy the REIT tax qualification requirement that we distribute at least 90% of our annual ordinary taxable income to our stockholders. Furthermore, we may borrow if we otherwise deem it necessary or advisable to ensure that we maintain our qualification as a REIT for U.S. federal income tax purposes. We have historically maintained a low leveraged balance sheet and intend to continue to maintain this structure over the long run. However, our total leverage may fluctuate on a short term basis as we execute our business strategy.

High debt levels will cause us to incur higher interest charges, which would result in higher debt service payments and could be accompanied by restrictive covenants. If there is a shortfall between the cash flow from a property and the cash flow needed to service mortgage debt on that property, then the amount available for distributions to our 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, thus reducing the value of the Company. For tax purposes, a foreclosure of any of our properties will 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 will 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 to our affiliated entities that own our properties. When we give a guaranty on behalf of an affiliated entity that owns one of our properties, we will be responsible to the lender for satisfaction of the debt if it is not paid by our affiliated entity. If any mortgage contains cross-collateralization or cross-default provisions, a default by us on a single property could affect multiple properties. If any of our properties are foreclosed upon due to a default by us, our ability to pay cash distributions to our stockholders could be adversely affected.

Covenants in the instruments governing our existing indebtedness limit our operational flexibility and a covenant breach could adversely affect our operations.

The terms of the instruments governing our existing indebtedness require us to comply with a number of customary financial and other covenants. These provisions include, among other things: a limitation on the incurrence of additional indebtedness; limitations on mergers; investments; acquisitions; redemptions of capital stock; transactions with affiliates; and maintenance of specified financial ratios. Our continued ability to incur debt and operate our business is subject to compliance with these covenants, which limit our operational flexibility. Breaches of these covenants could result in defaults by us under applicable debt instruments, even if payment obligations are satisfied. Financial and other covenants that limit our operational flexibility, as well as defaults resulting from our breach of any of these covenants in our debt instruments, could have an adverse effect on our financial condition and results of operations.

Table of Contents

Adverse changes in our credit ratings could impair our ability to obtain additional debt and equity financing on favorable terms, if at all, and negatively impact the market price of our securities, including our common stock.

Our credit ratings are based on our operating performance, liquidity and leverage ratios, overall financial position and other factors employed by the credit rating agencies in their rating analysis of us. Our credit ratings can affect the amount and type of capital we can access, as well as the terms of any financings we may obtain. There can be no assurance that we will be able to maintain our current credit ratings, and, in the event that our current credit ratings deteriorate, we would likely incur higher borrowing costs and it may be more difficult or expensive for us to obtain additional financing or refinance existing obligations and commitments. Also, a downgrade in our credit ratings would trigger additional costs or other potentially negative consequences for us under our current and future credit facilities and debt instruments.

Risks Related to Joint Ventures

The terms of joint venture agreements or other joint ownership arrangements into which we have entered and may enter could impair our cash flow, our operating flexibility and our results of operations.

In connection with the purchase of real estate, we have entered and may continue to enter into joint ventures with third parties. We may also purchase or develop properties in co-ownership arrangements with the sellers of the properties, developers or other persons. Our joint venture partners may also have rights to take actions over which we have no control and may take actions contrary to our interests. Joint ownership of an investment in real estate may involve risks not associated with direct ownership of real estate, including the following:


•	a venture partner may at any time have economic or other business interests or goals which are or become inconsistent with our business interests or goals, including inconsistent goals relating to the sale of properties held in a joint venture or the timing of the termination and liquidation of the venture;


•	a venture partner might become bankrupt and such proceedings could have an adverse impact on the operation of the partnership or joint venture;


•	a venture partner’s actions might have the result of subjecting the property to liabilities in excess of those contemplated; and


•	a venture partner may be in a position to take action contrary to our instructions or requests, or contrary to our policies or objectives, including our policy with respect to qualifying and maintaining our qualification as a REIT.

Under certain joint venture arrangements, neither venture partner may have the power to control the venture and, thus, an impasse could occur, which might adversely affect the joint venture and decrease potential returns to our stockholders. If we have a right of first refusal or buy/sell right to buy-out a venture partner, we may be unable to finance such a buy-out or we may be forced to exercise those rights at a time when it would not otherwise be in our best interest to do so. If our interest is subject to a buy/sell right in favor of us, we may not have sufficient cash, available borrowing capacity or other capital resources to allow us to purchase an interest of a venture partner subject to the buy/sell right, in which case we may be forced to sell our interest when we would otherwise prefer to retain our interest. In addition, we may not be able to sell our interest in a joint venture on a timely basis or on acceptable terms if we desire to exit the venture for any reason, particularly if our interest is subject to a right of first refusal in favor of our venture partner.

Federal Income Tax Risks

Failure to qualify as a REIT for U.S. federal income tax purposes would subject us to federal income tax on our taxable income at regular corporate rates, which would substantially reduce our ability to make distributions to our stockholders.

We elected to be taxed as a REIT for U.S. federal income tax purposes beginning with our taxable year ended December 31, 2007 and we believe that our current and intended manner of operation will enable us to continue to meet the requirements to be taxed as a REIT. To qualify as a REIT, we must meet various requirements set forth in the Code concerning, among other things, the ownership of our outstanding common stock, the nature of our assets, the sources of our income and the amount of our distributions to our stockholders. The REIT qualification requirements are extremely complex and interpretations of the federal income tax laws governing qualification as a REIT are limited. Accordingly, we cannot be certain that we will be successful in operating so as to qualify as a REIT. At any time, new laws, interpretations or court decisions may change the federal tax laws relating to, or the federal income tax consequences of, qualification as a REIT. It is possible that future economic, market, legal, tax or other considerations may cause our Board of Directors to revoke our REIT election, which it may do without stockholder approval.

Table of Contents

If we were to fail to qualify as a REIT for any taxable year, we would not be able to deduct distributions to stockholders in computing our taxable income and we would be subject to U.S. federal income tax on our taxable income at corporate rates. We could also be subject to the federal alternative minimum tax and increased state and local taxes. Losing our qualification as a REIT would reduce our net earnings available for investment or distribution to stockholders due to the additional tax liability and we would no longer be required to make distributions. To the extent that distributions had been made in anticipation of our qualifying as a REIT, we might be required to borrow funds or liquidate some investments in order to pay the applicable corporate income tax. In addition, we would generally be disqualified from treatment as a REIT for the four taxable years following the year in which we lose our qualification as a REIT.

As a result of all these factors, our failure to qualify as a REIT could impair our ability to expand our business and raise capital, and would substantially reduce our ability to make distributions to our stockholders.

To continue to qualify as a REIT and to avoid the payment of U.S. federal income and excise taxes, we may be forced to borrow funds, use proceeds from the issuance of securities or sell assets to pay distributions, which may result in our distributing amounts that may otherwise be used for our operations or cause us to forgo otherwise attractive opportunities.

To obtain the favorable tax treatment accorded to REITs, we normally will be required each year to distribute to our stockholders at least 90% of our REIT taxable income, determined without regard to the deduction for dividends paid and by excluding net capital gains. We will be subject to U.S. federal income tax on our undistributed taxable income and net capital gain and to a 4% nondeductible excise tax on any amount by which distributions we pay with respect to any calendar year are less than the sum of: (a) 85% of our ordinary income; (b) 95% of our capital gain net income; and (c) 100% of our undistributed income from prior years. These requirements could cause us to make distributions to our stockholders at disadvantageous times or when we do not have funds readily available for distribution, or we may be required to liquidate otherwise attractive investments. These requirements could additionally cause us to distribute amounts that otherwise would be spent on acquisitions of properties and it is possible that we might be required to borrow funds, use proceeds from the issuance of securities or sell assets in order to distribute enough of our taxable income to maintain our qualification as a REIT and to avoid the payment of federal income and excise taxes. Thus, compliance with the REIT requirements may hinder our ability to operate solely on the basis of maximizing profits.

To preserve our qualification as a REIT, our charter contains ownership limits with respect to our capital stock that may delay, defer or prevent a change of control of HTA or other transaction that may be benefit our stockholders.

To assist us in preserving our qualification as a REIT, our charter contains a limitation on ownership that prohibits any individual, entity or group, unless exempted by our Board of Directors, from directly acquiring beneficial ownership of more than 9.8% of the value of HTA’s then outstanding capital stock (which includes common stock and any preferred stock HTA may issue) or more than 9.8% of the value or number of shares, whichever is more restrictive, of HTA’s then outstanding common stock.

Any attempted transfer of HTA’s stock which, if effective, would result in HTA’s stock being beneficially owned by fewer than 100 persons will be null and void. Any attempted transfer of HTA’s stock which, if effective, would result in violation of the ownership limits discussed above or in HTA being “closely held” under Section 856(h) of the Code or otherwise failing to qualify as a REIT, will cause the number of shares causing the violation (rounded up to the nearest whole share) to be automatically transferred to a trust for the exclusive benefit of one or more charitable beneficiaries and the proposed transferee will not acquire any rights in the shares.

Recent tax legislative or regulatory action could adversely affect stockholders unitholders, or the Company, which may have an adverse impact to the value of the Company and could also impede our ability to source new capital.

On December 20, 2017, the House of Representatives and the Senate passed the TCJA which makes major changes to the Code, including a number of provisions of the Code that affect the taxation of REITs and their stockholders. Changes to the TCJA, with or without retroactive application, could materially and adversely affect our stockholders, OP Unit holders and/or us. The individual and collective impact of these provisions and other provisions of the TCJA on REITs and their stockholders is uncertain, and may not become evident for some period of time.

If tax rates were to change in a manner comparably favorable for regular corporate taxable income and dividends to that of REITs, investors could perceive investments in REITs to be relatively less attractive than investment in dividend paying non-REIT corporations, which could adversely affect the value of our common stock. Stockholders and potential investors should consult their tax advisors regarding their respective tax considerations and rates.

Risks Related to Our Common Stock

The price of our common stock has and may continue to fluctuate, which may make it difficult for you to sell our common stock when you want to do so, or at prices you find attractive.

The price of our common stock on the NYSE constantly changes and has been subject to price fluctuations. We expect that the market price of our common stock will continue to fluctuate. Our stock price can fluctuate as a result of a variety of factors, many of which are beyond our control. These factors may include:


•	actual or anticipated variations in our quarterly operating results;


•	changes in our earnings estimates or publication of research reports about us or the real estate industry, although no assurance can be given that any research reports about us will be published;


•	future sales of substantial amounts of common stock by our existing or future stockholders;


•	increases in market interest rates, which may lead purchasers of our stock to demand a higher yield;


•	changes in market valuations of similar companies;


•	adverse market reaction to any increased indebtedness we incur in the future;


•	additions or departures of key personnel;


•	actions by institutional stockholders;


•	speculation in the press or investment community; and


•	general market and economic conditions.

In addition, the stock market in general may experience extreme volatility that may be unrelated to the operating performance of a particular company. These broad market fluctuations may adversely affect the market price of our common stock.

Future offerings of debt securities, which would be senior to our common stock, or equity securities, which would dilute our existing stockholders and may be senior to our common stock, may adversely affect the market price of our common stock.

In the future, we may issue debt or equity securities, including medium term notes, senior or subordinated notes and classes of preferred or common stock. Debt securities or shares of preferred stock will generally be entitled to receive distributions, both current and in connection with any liquidation or sale, prior to the holders of our common stock. Our Board of Directors may issue such securities without stockholder approval and under Maryland law may amend our charter to increase the aggregate number of authorized shares of capital stock or the number of authorized shares of capital stock of any class or series without stockholder approval. We are not required to offer any such additional debt or equity securities to existing holders of our common stock on a preemptive basis. Therefore, offerings by us of our common stock or other equity securities may dilute the percentage ownership interest of our existing stockholders. To the extent we issue additional equity interests, our stockholders’ percentage ownership interest in us will be diluted. Depending upon the terms and pricing of any additional offerings and the value of our properties and other real estate related assets, our stockholders may also experience dilution in both the book value and fair market value of their shares. As a result, future offerings of our debt or equity securities, or the perception that such offerings may occur, may reduce the market price of our common stock and/or the distributions that we pay with respect to our common stock.

The availability and timing of cash distributions to our stockholders is uncertain, which could adversely affect the market price of our common stock and may include a return of capital.

Our organizational documents do not establish a limit on the amount of net proceeds we may use to fund distributions. All distributions, however, will be at the sole discretion of our Board of Directors and will depend upon our actual and projected financial condition, results of operations, cash flows, liquidity and FFO, maintenance of our REIT qualification and such other matters as our Board of Directors may deem relevant from time to time. We cannot assure our stockholders that sufficient cash will be available to make distributions or that the amount of distributions will increase over time. Our failure to meet the market’s expectations with regard to future cash distributions likely would adversely affect the market price of our common stock.

Table of Contents

Increases in market interest rates and related risks may cause the value of our investments in real estate related assets to be reduced and could result in a decrease in the value of our common stock.

One of the factors that may influence the price of our common stock will be the dividend distribution rate on our common stock (as a percentage of the price of our common stock) relative to market interest rates. If market interest rates rise, prospective purchasers of common stock may expect a higher distribution rate. Higher interest rates would not, however, result in more funds being available for distribution. In fact, if market interest rates rise, the market value of our fixed income securities would likely decline, our borrowing costs would likely increase and our funds available for distribution would likely decrease. During periods of rising interest rates, the average life of certain types of securities may be extended because of slower than expected principal payments. This may lock in a below-market interest rate, increase the security’s duration and reduce the value of the security. During periods of declining interest rates, an issuer may be able to exercise an option to prepay principal earlier than scheduled, which may force us to reinvest in lower yielding securities. Preferred and debt securities frequently have call features that allow the issuer to repurchase the security prior to its stated maturity. An issuer may redeem an obligation if the issuer can refinance the debt at a lower cost due to declining interest rates or an improvement in the credit standing of the issuer. These risks may reduce the value of our investments in real estate related assets. Therefore, we may not be able, or we may not choose, to provide a higher distribution rate. As a result, prospective purchasers may decide to purchase other securities rather than our common stock, which would reduce the demand for, and result in a decline in the market price of, our common stock.

Item 2. Properties

We have invested $7.0 billion in MOBs, projects under development and other healthcare real estate assets that serve the healthcare industry through December 31, 2017. As of December 31, 2017, our portfolio consisted of approximately 24.1 million square feet of GLA, with a leased rate of 91.8% (includes leases which have been executed, but which have not yet commenced). Approximately 70% of our portfolio was located on the campuses of, or adjacent to, nationally and regionally recognized healthcare systems. Our portfolio is diversified geographically across 33 states, with no state having more than 19% of the total GLA as of December 31, 2017. All but three of our properties are 100% owned.

As of December 31, 2017, we owned fee simple interests in properties representing 62% of our total GLA. We hold long-term leasehold interests in the remaining properties in our portfolio, representing 38% of our total GLA. As of December 31, 2017, these leasehold interests had an average remaining term of 52.6 years not including any available extension options. Including all extension options available to us, our average remaining term would be 71.3 years.

The following information generally applies to our properties:


•	we believe all of our properties are adequately covered by insurance and are suitable for their intended purposes;


•	our properties are located in markets where we are subject to competition in attracting new tenants and retaining current tenants; and


•	depreciation is provided on a straight-line basis over the estimated useful lives of the buildings, up to 39 years, and over the shorter of the lease term or useful lives of the tenant improvements.

Executive Summary

HTA is the largest publicly-traded REIT focused on MOBs in the U.S. as measured by the GLA of its MOBs. HTA conducts substantially all of its operations through HTALP. We invest in MOBs that we believe will serve the future of healthcare delivery and MOBs that are primarily located on health system campuses, near university medical centers, or in core community outpatient locations. We also focus on our key markets that have certain demographic and macro-economic trends and where we can utilize our institutional full-service property management, leasing and development services platform to generate strong tenant and health system relationships and operating cost efficiencies. Our primary objective is to maximize stockholder value with disciplined growth through strategic investments that provide an attractive risk-adjusted return for our stockholders by consistently increasing our cash flow. In pursuing this objective, we: (i) seek internal growth through proactive asset management, leasing, building services and property management oversight; (ii) target accretive acquisitions and developments of MOBs in markets with attractive demographics that complement our existing portfolio; and (iii) actively manage our balance sheet to maintain flexibility with conservative leverage. Additionally, from time to time we consider, on an opportunistic basis, significant portfolio acquisitions that we believe fit our core business and could enhance our existing portfolio.

Since 2006, we have invested $7.0 billion to create a portfolio of MOBs, development projects and other healthcare assets consisting of approximately 24.1 million square feet of GLA throughout the U.S. Approximately 70% of our portfolio was located on the campuses of, or adjacent to, nationally and regionally recognized healthcare systems. Our portfolio is diversified geographically across 33 states, with no state having more than 19% of our total GLA as of December 31, 2017. We are concentrated in 20 to 25 key markets that are experiencing higher economic and demographic trends than other markets, on average, that we expect will drive demand for MOBs. As of December 31, 2017, we had approximately 1 million square feet of GLA in each of our top ten markets and approximately 93% of our portfolio, based on GLA, is located in the top 75 MSAs, with Dallas, Houston, Boston, Tampa and Atlanta being our largest markets by investment.

Key Market Focused Strategy and Investments

We believe we have been one of the most active investors in the medical office sector over the last decade. This has enabled us to create a high quality portfolio focused on MOBs serving the future of healthcare with scale and significance in 20 to 25 key markets.

•

Our investments strategy includes alignment with key healthcare systems, hospitals, and leading academic medical universities. The Company is the largest owner of on-campus or adjacent MOBs in the country, with approximately 16.9 million square feet of GLA, or 70%, of our portfolio located in these locations. The remaining 30% are located in core community outpatient locations where healthcare is increasingly being delivered.

•

Over the last several years, our investments have been focused in our 20 to 25 key markets which we believe will outperform the broader U.S. from an economic and demographic perspective. As of December 31, 2017, approximately 93% of our portfolio’s GLA is located in top 75 MSAs. Our key markets represent top MSAs with strong growth metrics in jobs, household income and population, as well as low unemployment and mature healthcare infrastructures. Many of our key markets are also supported by strong university systems.

•

Our key market focus has enabled us to establish scale and effectively utilize our internal property management and leasing platform to deliver consistent same store growth and additional yield on investments, and also cost effective service to tenants. As of December 31, 2017, we had approximately 1 million square feet of GLA in each of our top ten markets and approximately 500,000 square feet in each of our top 16 markets. We expect to establish this scale across 20 to 25 key markets as our portfolio expands.


•	During the year ended December 31, 2017, we completed investments totaling $2.7 billion, including the Duke Acquisition of $2.25 billion, net of development credits we received at closing, projects under development, which were located substantially in certain of our 20 to 25 key markets. Our 2017 investments represents an increase in total GLA of approximately 36% compared to 2016.


•	During the year ended December 31, 2017, we completed dispositions of four MOBs located in Wisconsin, California and Texas for an aggregate sales price of $85.2 million, generating gains of $37.8 million.

Internal Growth through Proactive In-House Property Management and Leasing

We believe we have the largest full-service operating platform in the medical office space that consists of our in-house property management and leasing which allows us to better manage and service our existing portfolio. In each of these markets, we have established a strong in-house property management and leasing platform that has allowed us to develop valuable relationships with health systems, physician practices, universities, and regional development firms that have led to investment and leasing opportunities. Our full-service operational platforms have also enabled us to focus on generating cost efficiencies as we gain scale across individual markets and regions.


•	As of December 31, 2017, our in-house property management and leasing platform operated approximately 22.4 million square feet of GLA, or 93%, of our total portfolio, a significant increase from 8.8 million square feet, or 70%, of GLA managed in-house in 2012.


•	As of December 31, 2017, our leased rate (includes leases which have been executed, but which have not yet commenced) was 91.8% by GLA and our occupancy rate was 91.0% by GLA.


•	We entered into new and renewal leases on approximately 2.7 million square feet of GLA, or 11.2% of our portfolio, for the year ended December 31, 2017.

•

During the year ended December 31, 2017, tenant retention for the Same-Property portfolio was 78%, which included approximately 1.5 million square feet of GLA of expiring leases, which we believe is indicative of our commitment to maintaining buildings in desirable locations and fostering strong tenant relationships. Tenant retention is defined as the sum of the total leased GLA of tenants that renewed a lease during the period over the total GLA of leases that renewed or expired during the period.

Financial Strategy and Balance Sheet Flexibility

•

As of December 31, 2017, we had total leverage, measured by net debt (total debt less cash and cash equivalents) to total capitalization, of 29.9%. Total liquidity was $1.2 billion, including cash and cash equivalents of $100.4 million, a $75.0 million forward commitment and $991.2 million available on our unsecured revolving credit facility (includes the impact of $8.8 million of outstanding letters of credit) as of December 31, 2017.

•

During the year ended December 31, 2017, we issued and sold $1.8 billion of equity at an average price of $28.76 per share and entered a forward sale arrangement pursuant to a forward equity agreement, with anticipated net proceeds of approximately $75.0 million to be settled in April 2018, subject to adjustments as provided in the forward equity agreement. Our equity issued during the year consisted of $1.6 billion from the sale of common stock in an underwritten public offering at an average price of $28.50 per share, $125.7 million from the sale of common stock under our previous ATM at an average price of $31.45 per share, approximately $124.3 million from the sale of common stock under the new ATM at an average price of $29.60 per share and $1.1 million from the issuance of OP Units in connection with two acquisition transactions.


•	In June 2017, we issued in a public offering (i) $400.0 million of 5-year unsecured senior notes, with a coupon of 2.95% per annum and (ii) $500.0 million of 10-year unsecured senior notes, with a coupon of 3.75% per annum.

In addition, as part of the Duke Acquisition, we were required by the seller to execute, as the borrower, a $286.0 million Promissory Note. The Promissory Note has an interest rate of 4.0% per annum, maturing in 2020.

•

On July 27, 2017, we entered into an amended and restated $1.3 billion Unsecured Credit Agreement which increased the amount available under the unsecured revolving credit facility to $1.0 billion and extended the maturities of the unsecured revolving credit facility to June 30, 2022 and for the $300.0 million unsecured term loan until February 1, 2023. The interest rate on the unsecured revolving credit facility is adjusted LIBOR plus a margin ranging from 0.83% to 1.55% per annum based on HTA’s credit rating.


•	On February 15, 2018, our Board of Directors announced a quarterly dividend of $0.305 per share/unit of common stock.

Critical Accounting Policies

The preparation of financial statements in conformity with GAAP requires our management to use judgment in the application of accounting principles, including making estimates. We base our estimates on experience and various other assumptions we believe are reasonable under the circumstances. These estimates affect the reported amount of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting periods. However, if our judgment or interpretation of the facts and circumstances relating to the various transactions or other matters had been different, it is possible that different accounting would have been applied, resulting in different presentation of our financial statements. We periodically reevaluate our estimates and in the event they prove to be different from actual results, we make adjustments in subsequent periods to reflect more current estimates about matters that are inherently uncertain. Below is a discussion of accounting policies that we consider critical as they may require more complex judgment in their application or require estimates about matters that are inherently uncertain. For further information on significant accounting policies that impact us, see Note 2 - Summary of Significant Accounting Policies to the accompanying consolidated financial statements.

Basis of Presentation

Our accompanying consolidated financial statements include our accounts and those of our wholly-owned subsidiaries and joint venture entities in which we own a majority interest with the ability control operations. We consolidate variable interest entities (“VIEs”) when we are the primary beneficiary. All inter-company balances and transactions have been eliminated in the accompanying consolidated financial statements.

We make judgments with respect to our level of influence or control and whether we are (or are not) the primary beneficiary of a VIE. Consideration of various factors includes, but is not limited to, our ability to direct the activities that most significantly impact the entity’s economic performance, our form or ownership interest, our representation on the entity’s governing body, the size and seniority of our investment, our ability and rights of other investors to participate in policy making decisions, replace the manager and/or liquidate the entity, if applicable. Our ability to correctly assess our influence or control over an entity when determining the primary beneficiary of a VIE affects the presentation of these entities in our consolidated financial statements. If we perform a primary beneficiary analysis at a date other than at inception of the VIE, our assumptions may be different and may result in the identification of a different primary beneficiary.

Revenue Recognition

Rental revenue is our primary source of revenue. At the inception of a new lease we assess the terms and conditions to determine proper classification. If the estimates utilized by us in our assessment were different, then our lease classification for accounting purposes may have been different, which could impact the timing and amount of revenue recognized. We recognize rental revenue from operating leases on a straight-line basis over the term of the related lease (including rent holidays). Tenant reimbursement revenue, which is comprised of additional amounts recoverable from tenants for common area maintenance expenses and certain other recoverable expenses, is recognized as revenue in the period in which the related expenses are incurred. Effective January 1, 2018, with the adoption of Topic 606, the revenue recognition process will be based on a five-step model to account for revenue arising from contracts with customers and supersedes most of the existing revenue recognition guidance. Topic 606 requires an entity to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. For more detailed information on Topic 606, see “Recently Issued or Adopted Accounting Pronouncements” in Note 2 - Summary of Significant Accounting Policies to the accompanying consolidated financial statements.

Allowance for Uncollectible Accounts

Tenant receivables, including straight-line rent receivables, are carried net of the allowances for uncollectible amounts. An allowance is maintained for estimated losses resulting from the inability of certain tenants to meet the contractual obligations under their leases. Our determination of the adequacy of these allowances requires judgment and is based primarily upon evaluations of historical loss experience, the tenant’s financial condition, security deposits, letters of credit, lease guarantees, current economic conditions and other relevant factors. Our estimates may differ from actual results, which could significantly impact our consolidated financial statements.

Investments in Real Estate

With the adoption of ASU 2017-01 in January 2017 we expect the majority of our future investments in real estate investments will be accounted for as asset acquisitions and to record the purchase price to tangible and intangible assets and liabilities based on their relative fair values. Tangible assets primarily consist of land and buildings and improvements. Additionally, the purchase price includes acquisition related expenses, above or below market leases, above or below market leasehold interests, in place leases, tenant relationships, above or below market debt assumed, interest rate swaps assumed and any contingent consideration recorded when the contingency is resolved. The determination of the fair value requires us to make certain estimates and assumptions.

The fair value of the land and buildings and improvements is based upon our determination of the value of the property as if it were to be replaced or as if it were vacant using discounted cash flow models similar to those used by market participants. Factors considered by us include an estimate of carrying costs during the expected lease-up periods considering current market conditions and costs to execute similar leases.

The value of in place leases is based on our evaluation of the specific characteristics of each tenant’s lease. The factors considered include estimated lease-up periods, market rent and other market conditions.

We analyze the acquired leases to determine whether the rental rates are above or below market. The value associated with above or below market leases is based upon the present value (using a discount rate which reflects the risks associated with the acquired leases) of the difference between (i) the contractual amounts to be received pursuant to the lease over its remaining term and (ii) our estimate of the amounts that would be received using fair market rates over the remaining term of the lease.

We analyze the acquired leasehold interests to determine whether the rental rates are above or below market. The value associated with above or below market leasehold interests is based upon the present value (using a discount rate which reflects the risks associated with the acquired leases) of the difference between (i) the contractual amounts to be paid pursuant to the lease over its remaining term and (ii) our estimate of the amounts that would be paid using fair market rates over the remaining term of the lease.

We record debt or interest rate swaps assumed at fair value. The amount of above or below market debt is determined based upon the present value of the difference between the cash flow stream of the assumed mortgage and the cash flow stream of a market rate mortgage. The value of interest rate swaps is based upon a discounted cash flow analysis on the expected cash flows, taking into account interest rate curves and the period to maturity.

Table of Contents

We are required to make certain estimates in order to determine the fair value of the tangible and intangible assets and liabilities acquired in a business investment. Our assumptions directly impact our results of operations, as amounts allocated to certain assets and liabilities have different depreciation and amortization lives. In addition, the amortization and depreciation of these assets and liabilities are recorded in different line items in our accompanying consolidated statements of operations.

Recoverability of Real Estate Investments

Real estate investments are evaluated for potential impairment whenever events or changes in circumstances indicate that its carrying amount may not be recoverable. Impairment losses are recorded when indicators of impairment are present and the carrying amount of the asset is greater than the sum of future undiscounted cash flows expected to be generated by that asset over the remaining expected holding period. We would recognize an impairment loss when the carrying amount is not recoverable to the extent the carrying amount exceeds the fair value of the property. The fair value is generally based on discounted cash flow analyses. In performing the analysis we consider executed sales agreements or management’s best estimate of market comparables, future occupancy levels, rental rates, capitalization rates, lease-up periods and capital requirements.

Recently Issued or Adopted Accounting Pronouncements

See Note 2 - Summary of Significant Accounting Policies to our accompanying consolidated financial statements for a discussion of recently issued or adopted accounting pronouncements.

Factors Which May Influence Results of Operations

We are not aware of any material trends or uncertainties, other than national economic conditions affecting real estate generally and the risk factors previously listed in Part I, Item 1A - Risk Factors, that may reasonably be expected to have a material impact, favorable or unfavorable, on revenues or income from the investment, management and operation of our properties.

Rental Income

The amount of rental income generated by our properties depends principally on our ability to maintain the occupancy rates of currently leased space and to lease currently available space and space that will become available from unscheduled lease terminations at the then applicable rental rates. Negative trends in one or more of these factors could adversely affect our rental income in future periods.

Investment Activity

During the years ended December 31, 2017, 2016 and 2015, we had investments with an aggregate purchase price of $2.7 billion, $700.8 million and $280.9 million, respectively. During the years ended December 31, 2017, 2016 and 2015, we had dispositions with an aggregate sales price of $85.2 million, $39.5 million and $35.7 million, respectively. The amount of any future acquisitions or dispositions could have a significant impact on our results of operations in future periods.

Contractual rental income, which includes expense reimbursements, increased $144.4 million for the year ended December 31, 2017, compared to the December 31, 2016. This increase was primarily due to $138.9 million of additional contractual rental income from our 2016 and 2017 acquisitions (including properties owned during both periods) for the year ended December 31, 2017, and contractual rent increases, partially offset by a decrease in contractual rent as a result of buildings we sold during 2016 and 2017. Contractual rental income, which includes expense reimbursements, increased $55.2 million for the year ended December 31, 2016, compared to the year ended December 31, 2015. This increase was primarily due to $55.3 million of additional contractual rental income from our 2015 and 2016 acquisitions (including properties owned in both periods) and contractual rent increases, partially offset by a decrease in contractual rent as a result of the buildings we sold during 2015 and 2016.

Rental Expenses

For the years ended December 31, 2017, 2016 and 2015, rental expenses attributable to our properties were $192.1 million, $143.8 million and $123.4 million, respectively. The increase in rental expenses for the year ended December 31, 2017 compared to 2016, was primarily due to $51.4 million of additional rental expenses associated with our 2016 and 2017 acquisitions for the year ended December 31, 2017, partially offset by improved operating efficiencies and a decrease in rental expenses as a result of the buildings we sold during 2016 and 2017. The increase in rental expenses for the year ended December 31, 2016, compared to 2015, was primarily due to $24.6 million of additional rental expenses with our 2015 and 2016 acquisitions for the year ended December 31, 2016, partially offset by improved operating efficiencies and a decrease in rental expenses as a result of the buildings we sold during 2015 and 2016.

General and Administrative Expenses

For the years ended December 31, 2017, 2016 and 2015, general and administrative expenses were $33.4 million, $28.8 million and $25.6 million, respectively. These increases in general and administrative expenses were primarily due to an increase in non-cash compensation expense and an overall increase in head count due to the continued growth of the company. General and administrative expenses include such costs as salaries, corporate overhead and professional fees, among other items.

Transaction Expenses

For the years ended December 31, 2017, 2016 and 2015, transaction expenses were $5.9 million, $6.5 million and $4.6 million, respectively. The overall increases in transaction expenses are primarily due to the increased acquisition activity. Additionally, in 2017, transaction costs reflect the prospective presentation of the early adoption of ASU 2017-01 as of January 1, 2017, including $4.6 million of non-incremental costs related to the Duke Acquisition. As a result of the adoption, a significant portion of these expenses are now capitalized as part of our investment allocations.

Depreciation and Amortization Expense

For the years ended December 31, 2017, 2016 and 2015, depreciation and amortization expense was $245.0 million, $176.9 million and $154.1 million, respectively. These increases in depreciation and amortization expense year to year were primarily due to the increase in the size of our portfolio.

Impairment

During the year ended December 31, 2017, we recorded impairment charges of $13.9 million related to two MOBs and a portfolio of MOBs located in Massachusetts, South Carolina and Texas. During the year ended December 31, 2016, we recorded impairment charges of $3.1 million that related to two MOBs in our portfolio. During the year ended December 31, 2015 we recorded impairment charges of $2.6 million that related to two MOBs in our portfolio.

Interest Expense and Net Change in Fair Value of Derivative Financial Instruments

Interest expense, excluding the impact of the net change in fair value of derivative financial instruments, increased by $24.2 million during the year ended December 31, 2017, compared to 2016. The increase was primarily the result of higher average debt outstanding during the year ended December 31, 2017, as a result of partially funding our investments over the last 12 months with debt and a change in the composition of debt, driven by an increase in long-term senior unsecured notes, including the $350.0 million 10-year senior unsecured notes issued in July 2016 at a coupon rate of 3.50% per annum, the $400.0 million and $500.0 million 5-year and 10-year senior unsecured notes issued in June 2017 at a coupon rate of 2.95% per annum and 3.75% per annum, respectively.

During the year ended December 31, 2017, the fair market value of our derivatives increased $0.9 million compared to a net increase of $1.3 million during the year ended December 31, 2016. During the year ended December 31, 2016, the fair market value of our derivatives increased $1.3 million, compared to a net decrease of $0.8 million during the year ended December 31, 2015.

To achieve our objectives, we borrow at both fixed and variable rates. From time to time, we also enter into derivative financial instruments, such as interest rate swaps, in order to mitigate our interest rate risk on a related financial instrument. We do not enter into derivative or interest rate transactions for speculative purposes. Derivatives not designated as hedges are not speculative and are used to manage our exposure to interest rate movements.

Gain on Sales of Real Estate

For the year ended December 31, 2017, we realized gains of $37.8 million from the disposition of four MOBs located in Wisconsin, California and Texas. For the year ended December 31, 2016, we realized net gains of $9.0 million from the disposition of six senior care facilities located in Texas and California. For the year ended December 31, 2015, we realized net gains of $0.2 million from the disposition of six MOBs.

Gain or Loss on Extinguishment of Debt

For the year ended December 31, 2017 and 2016, we realized a net loss on extinguishment of debt of $11.2 million and $3.0 million, respectively. For the year ended December 31, 2015, we realized a net gain on extinguishment of debt of $0.1 million. The increased loss in 2017 was primarily due to fees we incurred in connection with the execution and our termination of the senior unsecured bridge loan facility (the “Bridge Loan Facility”) as part of the Duke Acquisition.

Table of Contents

Other Income and Expense

For the year ended December 31, 2017 and 2016, we had other income of $29,000 and $0.3 million, respectively. For the year ended December 31, 2015, we had other expense of $1.4 million. The net decrease for the year ended December 31, 2015, compared to 2016, was primarily due to the acceleration of management fees paid in connection with an acquisition-related management agreement that was entered into upon the date of acquisition.

NOI and Same-Property Cash NOI

NOI increased $104.7 million to $421.8 million for the year ended December 31, 2017, compared to the year ended December 31, 2016. The increase was primarily due to $96.2 million of additional NOI from our 2016 and 2017 acquisitions for the year ended December 31, 2017, partially offset by a decrease in NOI as a result of the buildings we sold during 2016 and 2017 and a reduction in straight-line rent from properties we owned more than a year. NOI increased $36.7 million to $317.2 million for the year ended December 31, 2016, compared to the year ended December 31, 2015. This increases was primarily due to $35.8 million of additional NOI from our 2015 and 2016 acquisitions, partially offset by a decrease in NOI as a result of the buildings we sold during 2015 and 2016, and a reduction in straight-line rent from properties we owned more than a year.

Same-Property Cash NOI increased $8.0 million to $284.8 million for the year ended December 31, 2017, compared to the year ended December 31, 2016. Same-Property Cash NOI increased $7.3 million to $258.3 million for the year ended December 31, 2016, compared to the year ended December 31, 2015. These increases were primarily the result of rent escalations, an increase in average occupancy, and improved operating efficiencies.

Non-GAAP Financial Measures

FFO and Normalized FFO

We compute FFO in accordance with the current standards established by NAREIT. NAREIT defines FFO as net income or loss attributable to common stockholders/unitholders (computed in accordance with GAAP), excluding gains or losses from sales of real estate property and impairment write-downs of depreciable assets, plus depreciation and amortization related to investments in real estate, and after adjustments for unconsolidated partnerships and joint ventures. We present this non-GAAP financial measure because we consider it an important supplemental measure of our operating performance and believe it is frequently used by securities analysts, investors and other interested parties in the evaluation of REITs. Historical cost accounting assumes that the value of real estate assets diminishes ratably over time. Since real estate values have historically risen or fallen based on market conditions, many industry investors have considered the presentation of operating results for real estate companies that use historical cost accounting to be insufficient by themselves. Because FFO excludes depreciation and amortization unique to real estate, among other items, it provides a perspective not immediately apparent from net income or loss attributable to common stockholders/unitholders.

We also compute Normalized FFO, which excludes from FFO: (i) transaction expenses; (ii) gain or loss on change in fair value of derivative financial instruments; (iii) gain or loss on extinguishment of debt; (iv) noncontrolling income or loss from OP Units included in diluted shares (only applicable to the Company); and (v) other normalizing items, which include items that are unusual and infrequent in nature. We present this non-GAAP financial measure because it allows for the comparison of our operating performance to other REITs and between periods on a consistent basis. Our methodology for calculating Normalized FFO may be different from the methods utilized by other REITs and, accordingly, may not be comparable to other REITs. Normalized FFO should not be considered as an alternative to net income or loss attributable to common stockholders/unitholders (computed in accordance with GAAP) as an indicator of our financial performance, nor is it indicative of cash available to fund cash needs. Normalized FFO should be reviewed in connection with other GAAP measurements.

The amounts included in the calculation of FFO and Normalized FFO are generally the same for HTALP and HTA, except for net income or loss attributable to common stockholders/unitholders, noncontrolling income or loss from OP Units included in diluted shares (only applicable to the Company) and the weighted average shares of our common stock or HTALP OP Units outstanding.

NOI, Cash NOI and Same-Property Cash NOI

NOI is a non-GAAP financial measure that is defined as net income or loss (computed in accordance with GAAP) before: (i) general and administrative expenses; (ii) transaction expenses; (iii) depreciation and amortization expense; (iv) impairment; (v) interest expense and net change in fair value of derivative financial instruments; (vi) gain or loss on sales of real estate; (vii) gain or loss on extinguishment of debt; (viii) income or loss from unconsolidated joint venture; and (ix) other income or expense. We believe that NOI provides an accurate measure of the operating performance of our operating assets because NOI excludes certain items that are not associated with the management of our properties. Additionally, we believe that NOI is a widely accepted measure of comparative operating performance of REITs. However, our use of the term NOI may not be comparable to that of other REITs as they may have different methodologies for computing this amount. NOI should not be considered as an alternative to net income or loss (computed in accordance with GAAP) as an indicator of our financial performance. NOI should be reviewed in connection with other GAAP measurements.

Cash NOI is a non-GAAP financial measure which excludes from NOI: (i) straight-line rent adjustments; and (ii) amortization of below and above market leases/leasehold interests. Contractual base rent, contractual rent increases, contractual rent concessions and changes in occupancy or lease rates upon commencement and expiration of leases are a primary driver of our revenue performance. We believe that Cash NOI, which removes the impact of straight-line rent adjustments, provides another measurement of the operating performance of our operating assets. Additionally, we believe that Cash NOI is a widely accepted measure of comparative operating performance of REITs. However, our use of the term Cash NOI may not be comparable to that of other REITs as they may have different methodologies for computing this amount. Cash NOI should not be considered as an alternative to net income or loss (computed in accordance with GAAP) as an indicator of our financial performance. Cash NOI should be reviewed in connection with other GAAP measurements.

Table of Contents

To facilitate the comparison of Cash NOI between periods, we calculate comparable amounts for a subset of our owned and operational properties referred to as “Same-Property”. Same-Property Cash NOI excludes properties which have not been owned and operated by us during the entire span of all periods presented, excluding properties intended for disposition in the near term, development and land parcels, our share of unconsolidated joint ventures, notes receivable interest income and certain non-routine items. Same-Property Cash NOI should not be considered as an alternative to net income or loss (computed in accordance with GAAP) as an indicator of our financial performance. Same-Property Cash NOI should be reviewed in connection with other GAAP measurements.

Liquidity and Capital Resources

Our primary sources of cash include: (i) cash flow from operations; (ii) borrowings under our unsecured revolving credit facility; (iii) net proceeds from the issuances of debt and equity securities; and (iv) proceeds from our dispositions. During the next 12 months our primary uses of cash are expected to include: (a) the funding of acquisitions of MOBs, development properties and other facilities that serve the healthcare industry; (b) capital expenditures; (c) the payment of operating expenses; (d) debt service payments, including principal payments; and (e) the payment of dividends to our stockholders. We anticipate cash flow from operations, restricted cash and reserve accounts and our unsecured revolving credit facility, if needed, will be sufficient to fund our operating expenses, capital expenditures and dividends to stockholders. Investments and maturing indebtedness may require funds from the issuance of debt and/or equity securities or proceeds from sales of real estate.

As of December 31, 2017, we had liquidity of $1.2 billion, including $991.2 million available under our unsecured revolving credit facility (which includes the impact of $8.8 million of outstanding letters of credit), $100.4 million of cash and cash equivalents and a $75.0 million forward commitment.

In addition, we had unencumbered assets with a gross book value of $6.2 billion. The unencumbered properties may be used as collateral to secure additional financings in future periods or refinance our current debt as it becomes due. Our ability to raise funds from future debt and equity issuances is dependent on our investment grade credit ratings, general economic and market conditions and our operating performance.

When we acquire a property, we prepare a capital plan that contemplates the estimated capital needs of that investment. In addition to operating expenses, capital needs may also include costs of refurbishment, tenant improvements or other major capital expenditures. The capital plan for each investment will be adjusted through ongoing, regular reviews of our portfolio or as necessary to respond to unanticipated additional capital needs. As of December 31, 2017, we estimate that our expenditures for capital improvements for 2018 will range from $35.0 million to $45.0 million depending on leasing activity. As of December 31, 2017, we had $3.1 million of restricted cash and reserve accounts for such capital expenditures. We cannot provide assurance, however, that we will not exceed these estimated expenditure levels.

If we experience lower occupancy levels, reduced rental rates, reduced revenues as a result of asset sales, or increased capital expenditures and leasing costs compared to historical levels due to competitive market conditions for new and renewal leases, the effect would be a reduction of net cash provided by operating activities. If such a reduction of net cash provided by operating activities is realized, we may have a cash flow deficit in subsequent periods. Our estimate of net cash available is based on various assumptions which are difficult to predict, including the levels of our leasing activity and related leasing costs. Any changes in these assumptions could impact our financial results and our ability to fund working capital and unanticipated cash needs.

Cash Flows

(1) The amounts for 2015 and 2016 differ from amounts previously reported in our Annual Reports for the years ended December 31, 2015 and 2016, as a result of the retrospective presentation of the early adoption of ASU 2016-18 as of January 1, 2017. Additionally the presentation of beginning of year and end of year cash now includes restricted cash as a result of the adoption of ASU 2016-18.

Net cash provided by operating activities increased in 2017 primarily due to the impact of our 2016 and 2017 acquisitions, contractual rent increases and improved operating efficiencies, partially offset by our 2016 and 2017 dispositions. Net cash provided by operating activities increased in 2016 primarily due to the impact of our 2015 and 2016 acquisitions, contractual rent increases and improved operating efficiencies, partially offset by our 2015 and 2016 dispositions. We anticipate cash flows from operating activities to increase as a result of the above items and continued leasing activity in our existing portfolio.

For the year ended December 31, 2017, net cash used in investing activities primarily related to the investment in real estate of $2.4 billion, investment in an unconsolidated joint venture of $68.8 million, and capital expenditures of $64.8 million, partially offset by proceeds from the sale of real estate of $80.6 million. For the year ended December 31, 2016, net cash used in investing activities primarily related to the investment in real estate of $592.0 million and capital expenditures of $43.0 million, partially offset by proceeds from the sale of real estate of $26.6 million. For the year ended December 31, 2015, net cash used in investing activities primarily related to investments in real estate of $279.3 million and capital expenditures of $29.3 million, partially offset by proceeds from the sales of real estate of $34.6 million. We anticipate cash flows used in investing activities to increase as we continue to acquire more properties.

For the year ended December 31, 2017, net cash provided by financing activities primarily related to the net proceeds of shares of common stock issued of $1.7 billion and net proceeds on the issuance of senior notes of $900.0 million, partially offset by dividends paid to holders of our common stock of $207.1 million, net payments on our unsecured revolving credit facility of $88.0 million, and payments on our secured mortgage loans of $77.0 million. For the year ended December 31, 2016, net cash provided by financing activities primarily related to the net proceeds of shares of common stock issued of $418.9 million and proceeds from unsecured senior notes of $347.7 million, partially offset by dividends paid to holders of our common stock of $159.2 million, net payments on our unsecured revolving credit facility of $130.0 million, and payments on our secured mortgage loans of $110.9 million. For the year ended December 31, 2015, net cash provided by financing activities primarily related to related to net borrowings of $282.0 million on our Unsecured Credit Agreement and net proceeds of shares of common stock issued of $44.3 million, partially offset by dividends paid to holders of our common stock of $146.4 million and payments on our mortgage loans of $94.9 million.

Dividends

The amount of dividends we pay to our stockholders is determined by our Board of Directors, in their sole discretion, and is dependent on a number of factors, including funds available, our financial condition, capital expenditure requirements and annual dividend distribution requirements needed to maintain our status as a REIT under the Internal Revenue Code of 1986, as amended. We have paid monthly or quarterly dividends since February 2007, and if our investments produce sufficient cash flow, we expect to continue to pay dividends to our stockholders. Because our cash available for dividend distributions in any year may be less than 90% of our taxable income for the year, we may obtain the necessary funds through borrowings, issuing new securities or selling assets to pay out enough of our taxable income to satisfy our dividend distribution requirement. Our organizational documents do not establish a limit on dividends that may constitute a return of capital for federal income tax purposes. The dividend we pay to our stockholders is equal to the distributions received from HTALP in accordance with the terms of HTALP’s partnership agreement. It is our intention to continue to pay dividends. However, our Board of Directors may reduce our dividend rate and we cannot guarantee the timing and amount of dividends that it may pay in the future, if any.

For the year ended December 31, 2017, we paid cash dividends of $207.1 million on our own common stock. In January 2018, we paid cash dividends on our own common stock of $62.5 million for the quarter ended December 31, 2017. On February 15, 2018, our Board of Directors announced a quarterly dividend of $0.305 per share/unit of common stock to be paid on April 10, 2018 to stockholders of record of our common stock and OP unitholders on April 3, 2018.

Financing

We have historically maintained a low leveraged balance sheet and intend to continue to maintain this structure in the long term. However, our total leverage may fluctuate on a short-term basis as we execute our business strategy. As of December 31, 2017, our leverage ratio, measured by net debt (total debt less cash and cash equivalents) to total capitalization, was 29.9%.

As of December 31, 2017, we had debt outstanding of $2.8 billion and the weighted average interest rate therein was 3.50% per annum, inclusive of the impact of our interest rate swaps. The following is a summary of our unsecured and secured debt. See Note 7 - Debt to our accompanying consolidated financial statements for a further discussion of our debt.

Unsecured Revolving Credit Facility

On July 27, 2017, HTALP entered into an amended and restated $1.3 billion Unsecured Credit Agreement which increased the amount available under the unsecured revolving credit facility to $1.0 billion. As of December 31, 2017, $991.2 million was available on our $1.0 billion unsecured revolving credit facility. Our unsecured revolving credit facility matures in June 2022.

Unsecured Term Loans

As of December 31, 2017, we had $500.0 million of unsecured term loans outstanding, comprised of $300.0 million under our Unsecured Credit Agreement maturing in 2023, and $200.0 million also maturing in 2023.

Unsecured Senior Notes

Table of Contents

As of December 31, 2017, we had $1.85 billion of unsecured senior notes outstanding, comprised of $300.0 million maturing in 2021, $400.0 million maturing in 2022, $300.0 million maturing in 2023, $350.0 million maturing in 2026, and $500.0 million maturing in 2027.

Mortgage Loans

In June 2017, as a part of the Duke Acquisition pursuant to a requirement of the seller, we entered as the borrower a $286.0 million Promissory Note which matures in January 2020. In addition, during the year ended December 31, 2017, we made payments on our mortgage loans of $77.0 million loans and have $102.5 million of principal payments due in 2018.

Commitments and Contingencies

See Note 9 - Commitments and Contingencies to our accompanying consolidated financial statements for a further discussion of our commitments and contingencies.

Debt Service Requirements

We are required by the terms of our applicable loan agreements to meet certain financial covenants, such as minimum net worth and liquidity, and reporting requirements, among others. As of December 31, 2017, we believe that we were in compliance with all such covenants and we are not aware of any covenants that it is reasonably likely that we would not be able to meet in accordance with our loan agreements.

Contractual Obligations

The table below presents our obligations and commitments to make future payments under our debt obligations and lease agreements as of December 31, 2017 (in thousands):



	Payment Due by Period
	Less than 1 Year		1-3 Years		3-5 Years		More than 5 Years		Total
Debt	$	102,513	$	254,354	$	768,835	$	1,676,740	$	2,802,442
Interest ⁽¹⁾	99,026		183,447		162,737		106,978		552,188

Total	$	212,447	$	460,013	$	954,470	$	2,699,898	$	4,326,828

(1) Interest on variable rate debt is calculated using the forward rates in effect at December 31, 2017 and excludes the impact of our interest rate swaps.

Off-Balance Sheet Arrangements

As of and during the year ended December 31, 2017, we had no material off-balance sheet arrangements that have had or are reasonably likely to have a current or future effect on our financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources.

Inflation

We are exposed to inflation risk as income from future long-term leases is the primary source of our cash flows from operations. There are provisions in the majority of our tenant leases that protect us from the impact of normal inflation. These provisions include rent escalations, reimbursement billings for operating expense pass-through charges and real estate tax and insurance reimbursements on a per square foot allowance. However, due to the long-term nature of our leases, among other factors, the leases may not reset frequently enough to cover inflation.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

Market risk includes risks that arise from changes in interest rates, foreign currency exchange rates, commodity prices, equity prices and other market changes that affect market sensitive instruments. In pursuing our business plan, we believe the primary market risk to which we have exposure is interest rate risk.

We are exposed to the effects of interest rate changes on our variable rate debt. Interest rate changes on our fixed rate debt will generally not affect our future earnings or cash flows unless such instruments mature or are otherwise terminated. Our interest rate risk is monitored using a variety of techniques. In order to mitigate our interest rate risk, we enter into derivative financial instruments such as interest rate swaps and caps. To the extent we enter into such derivative financial instruments, we are exposed to credit risk and market risk. Credit risk is the failure of the counterparty to perform under the terms of the derivative contract. When the fair value of a derivative contract is positive, the counterparty owes us, which creates credit risk for us. When the fair value of a derivative contract is negative, we owe the counterparty and, therefore, it does not possess credit risk. It is our policy to enter into these transactions with what we believe are high quality counterparties, including those with whom we have a lending relationship. We believe the likelihood of realized losses from counterparty non-performance is remote. We manage the market risk associated with interest rate swaps or caps by establishing and monitoring parameters that limit the types and degree of market risk that may be undertaken. We do not enter into derivative or interest rate transactions for speculative purposes.

The table below presents, as of December 31, 2017, the principal amounts of our fixed and variable debt and the weighted average interest rates, excluding the impact of interest rate swaps, by year of expected maturity to evaluate the expected cash flows and sensitivity to interest rate changes (in thousands, except interest rates):



	Expected Maturity Date
	2018			2019			2020			2021			2022			Thereafter			Total
Fixed rate debt	$	101,463		$	106,557		$	119,555		$	305,263		$	462,530		$	1,169,156		$	2,264,524
Weighted average interest rate on fixed rate debt (per annum)	4.08		%	4.21		%	4.42		%	3.41		%	3.29		%	3.67		%	3.63		%
Variable rate debt	$	1,050		$	1,119		$	27,123		$	509		$	533		$	507,584		$	537,918
Weighted average interest rate on variable rate debt based on forward rates in effect as of December 31, 2017 (per annum)	3.47		%	3.91		%	3.67		%	4.77		%	4.79		%	3.69		%	2.93		%

As of December 31, 2017, we had $2.8 billion of fixed and variable rate debt with interest rates ranging from 2.61% to 6.39% per annum and a weighted average interest rate of 3.49% per annum, excluding the impact of interest rate swaps. We had $2.3 billion (excluding net premium/discount and deferred financing costs) of fixed rate debt with a weighted average interest rate of 3.63% per annum and $537.9 million (excluding net premium/discount and deferred financing costs) of variable rate debt with a weighted average interest rate of 2.93% per annum as of December 31, 2017, excluding the impact of interest rate swaps.

As of December 31, 2017, the fair value of our fixed rate debt was $2.3 billion and the fair value of our variable rate debt was $539.2 million based upon prevailing market rates as of December 31, 2017.

As of December 31, 2017, we had interest rate swaps outstanding that effectively fix $189.4 million of our variable rate debt. Including the impact of these interest rate swaps, the effective rate on our variable rate and total debt is 2.98% and 3.50% per annum, respectively.

In addition to changes in interest rates, the value of our future properties is subject to fluctuations based on changes in local and regional economic conditions and changes in the creditworthiness of tenants, which may affect our ability to refinance our debt if necessary.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and the Board of Directors of Healthcare Trust of America, Inc.

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Healthcare Trust of America, Inc. and subsidiaries (the “Company”) as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements and financial statement schedules as of and for the year ended December 31, 2017, of the Company and our report dated February 20, 2018, expressed an unqualified opinion on those consolidated financial statements and financial statement schedules.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

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

Definition and Limitations of Internal Control over Financial Reporting

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

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

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and the Board of Directors of Healthcare Trust of America, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Healthcare Trust of America, Inc. and subsidiaries (the “Company”) as of December 31, 2017 and 2016, the related consolidated statements of operations, equity, comprehensive income (loss) and cash flows for each of the three years in the period ended December 31, 2017, and the related notes and the consolidated financial statement schedules listed in the Index at Item 15 (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and 2016, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2017, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 20, 2018, expressed an unqualified opinion on the Company’s internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

We have audited the accompanying consolidated balance sheets of Healthcare Trust of America Holdings, LP and subsidiaries (the “Company”) as of December 31, 2017 and 2016, the related consolidated statements of operations, changes in partners’ capital, comprehensive income (loss) and cash flows, for each of the three years in the period ended December 31, 2017, and the related notes and the financial statement schedules listed in the Index at Item 15 (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and 2016, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2017, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Unless otherwise indicated or unless the context requires otherwise the use of the words “we,” “us” or “our” refers to Healthcare Trust of America, Inc. and Healthcare Trust of America Holdings, LP, collectively.

1. Organization and Description of Business

HTA, a Maryland corporation, and HTALP, a Delaware limited partnership, were incorporated or formed, as applicable, on April 20, 2006. HTA operates as a REIT and is the general partner of HTALP, which is the operating partnership. As of December 31, 2017, HTA owned a 98.1% partnership interest and other limited partners, including some of our directors, executive officers and their affiliates, owned the remaining partnership interest (including the LTIP Units) in HTALP. As the sole general partner of HTALP, HTA has the full, exclusive and complete responsibility for HTALP’s day-to-day management and control. HTA operates in an umbrella partnership REIT structure in which HTALP and its subsidiaries hold substantially all of the assets. HTA’s only material asset is its ownership of partnership interests of HTALP. As a result, HTA does not conduct business itself, other than acting as the sole general partner of HTALP, issuing public equity from time to time and guaranteeing certain debts of HTALP. HTALP conducts the operations of the business and issues publicly-traded debt, but has no publicly-traded equity.

HTA is the largest publicly-traded REIT focused on MOBs in the U.S. as measured by the GLA of our MOBs. HTA conducts substantially all of its operations through HTALP. We invest in MOBs that we believe will serve the future of healthcare delivery, and MOBs that are primarily located on health system campuses, near university medical centers, or in core community outpatient locations. We also focus on our key markets that have certain demographic and macro-economic trends and where we can utilize our institutional full-service property management, leasing and development services platform to generate strong tenant and health system relationships and operating cost efficiencies. Our primary objective is to maximize stockholder value with disciplined growth through strategic investments that provide an attractive risk-adjusted return for our stockholders by consistently increasing our cash flow. In pursuing this objective, we: (i) seek internal growth through proactive asset management, leasing, building services and property management oversight; (ii) target accretive acquisitions and developments of MOBs in markets with attractive demographics that complement our existing portfolio; and (iii) actively manage our balance sheet to maintain flexibility with conservative leverage. Additionally, from time to time we consider, on an opportunistic basis, significant portfolio acquisitions that we believe fit our core business and could enhance our existing portfolio. HTA has qualified to be taxed as a REIT for federal income tax purposes and intends to continue to be taxed as a REIT.

Since 2006, we have invested $7.0 billion to create a portfolio of MOBs, development projects and other healthcare assets consisting of approximately 24.1 million square feet of GLA throughout the U.S. As of December 31, 2017, 70% of our portfolio was located on the campuses of, or adjacent to, nationally and regionally recognized healthcare systems. Our portfolio is diversified geographically across 33 states, with no state having more than 19% of our total GLA as of December 31, 2017. We believe these key locations and affiliations create significant demand from healthcare related tenants for our properties. Further, our portfolio is primarily concentrated within major U.S. metropolitan statistical areas (“MSAs”) that we believe will provide above-average economic growth and socioeconomic benefits over the coming years. As of December 31, 2017, we had approximately 1 million square feet of GLA in each of our top ten markets and approximately 93% of our portfolio, based on GLA, is located in the top 75 MSAs, with Dallas, Houston, Boston, Tampa and Atlanta being our largest markets by investment.

Our principal executive office is located at 16435 North Scottsdale Road, Suite 320, Scottsdale, Arizona, 85254.

2. Summary of Significant Accounting Policies

The summary of significant accounting policies presented below is designed to assist in understanding our consolidated financial statements. Such consolidated financial statements and the accompanying notes are the representations of our management, who are responsible for their integrity and objectivity. These accounting policies conform to GAAP in all material respects and have been consistently applied in preparing our accompanying consolidated financial statements.

Basis of Presentation

Our accompanying consolidated financial statements include our accounts and those of our subsidiaries and any consolidated VIEs. All inter-company balances and transactions have been eliminated in the accompanying consolidated financial statements.

Principles of Consolidation

The consolidated financial statements include the accounts of our subsidiaries and consolidated joint venture arrangements. The portions of the HTALP operating partnership not owned by us are presented as non-controlling interests in our consolidated balance sheets and statements of operations, consolidated statements of comprehensive income or loss, consolidated statements of equity, and consolidated statements of changes in partners’ capital. The portions of other joint venture arrangements not owned by us are presented as redeemable non-controlling interests in our consolidated balance sheets. In addition, as described in Note 1 - Organization and Description of Business, certain third parties have been issued OP Units in HTALP. Holders of OP Units are considered to be noncontrolling interest holders in HTALP and their ownership interests are reflected as equity in the consolidated balance sheets. Further, a portion of the earnings and losses of HTALP are allocated to noncontrolling interest holders based on their respective ownership percentages. Upon conversion of OP Units to common stock, any difference between the fair value of the common stock issued and the carrying value of the OP Units converted to common stock is recorded as a component of equity. As of December 31, 2017, 2016 and 2015, there were approximately 4.1 million, 4.3 million and 1.9 million, respectively, of OP Units issued and outstanding.

VIEs are entities where investors lack sufficient equity at risk for the entity to finance its activities without additional subordinated financial support or where equity investors, as a group, lack one of the following: (i) the power to direct the activities that most significantly impact the entity’s economic performance; (ii) the obligation to absorb the expected losses of the entity; and (iii) the right to receive the expected returns of the entity. We consolidate our investment in VIEs when we determine that we are the primary beneficiary. A primary beneficiary is one that has both: (i) the power to direct the activities of the VIE that most significantly impacts the entity’s economic performance; and (ii) the obligation to absorb losses or the right to receive benefits of the VIE that could be significant to the entity. The HTALP operating partnership and our other joint venture arrangements are VIEs because the limited partners in those partnerships, although entitled to vote on certain matters, do not possess kick-out rights or substantive participating rights. Additionally, we determined that we are the primary beneficiary of our VIEs. Accordingly, we consolidate our interests in the HTALP operating partnership and in our other joint venture arrangements. However, because we hold what is deemed a majority voting interest in the HTALP operating partnership and our other joint venture arrangements, it qualifies for the exemption from providing certain disclosure requirements associated with investments in VIEs. We will evaluate on an ongoing basis the need to consolidate entities based on the standards set forth in GAAP as described above.

Use of Estimates

The preparation of our consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. These estimates are made and evaluated on an ongoing basis using information that is currently available as well as various other assumptions believed to be reasonable under the circumstances. Actual results could differ from those estimates, perhaps in adverse ways, and those estimates could be different under different assumptions or conditions.

Reclassification

In November 2016, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2016-18 Statement of Cash Flows: Restricted Cash. ASU 2016-18 requires that a statement of cash flows explain the change during the period in cash, cash equivalents and restricted cash or restricted cash equivalents. Therefore, restricted cash or restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning of year and end of year amounts shown on the statement of cash flows. We adopted ASU 2016-18 as of January 1, 2017, and as a result of the adoption, the guidance requires retrospective adoption for all periods presented. The following table represents the previously reported balances and the reclassified balances for the impacted items of the December 31, 2016 and 2015 consolidated statements of cash flows (in thousands):



	Year Ended December 31, 2016						Year Ended December 31, 2015
	As Previously Reported			As Reclassified			As Previously Reported			As Reclassified
Cash flows from investing activities:
Other assets ⁽¹⁾	$	2,078		$	—		$	4,711		$	(196	)
Net cash used in investing activities	(606,315		)	(608,393		)	(269,264		)	(274,171		)

Cash, cash equivalents and restricted cash - end of year ⁽²⁾	$	11,231		$	25,045		$	13,070		$	28,962

(1) Prior to adoption of ASU 2016-18 line item description was Restricted cash, escrow deposits and other assets.
(2) With the adoption of ASU 2016-18 line item description now includes restricted cash.

Cash, Cash Equivalents and Restricted Cash

Cash and cash equivalents consist of all highly liquid investments with a maturity of three months or less when purchased. Restricted cash is comprised of reserve accounts for property taxes, insurance, capital improvements and tenant improvements as well as collateral accounts for debt and interest rate swaps and deposits for future investments.

With our adoption of ASU 2016-18 the following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the accompanying consolidated balance sheets to the combined amounts shown on the accompanying consolidated statements of cash flows (in thousands):



	December 31,
	2017		2016		2015
Cash and cash equivalents	$	100,356	$	11,231	$	13,070
Restricted cash	18,204		13,814		15,892
Total cash, cash equivalents and restricted cash	$	118,560	$	25,045	$	28,962

Revenue Recognition

Minimum annual rental revenue is recognized on a straight-line basis over the term of the related lease (including rent holidays). Differences between rental income recognized and amount contractually due under the lease agreements are recorded as straight-line rent receivables. Tenant reimbursement revenue, which is comprised of additional amounts recoverable from tenants for common area maintenance expenses and certain other recoverable expenses, is recognized as revenue in the period in which the related expenses are incurred. Tenant reimbursements are recorded on a gross basis, as we are generally the primary obligor with respect to purchasing goods and services from third-party suppliers, have discretion in selecting the supplier, and have credit risk. We recognize lease termination fees when there is a signed termination letter agreement, all of the conditions of the agreement have been met, and the tenant is no longer occupying the property. Rental income is reported net of amortization of inducements. Effective January 1, 2018, with the adoption of Topic 606 and corresponding amendments, the revenue recognition process will be based on a five-step model to account for revenue arising from contracts with customers and supersedes most of the existing revenue recognition guidance. Topic 606 requires an entity to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. As a REIT, our revenue is primarily generated through leasing contracts, which are excluded from Topic 606. The impact of Topic 606 will be concentrated in the recognition of our non-lease revenue streams. For more detailed information on Topic 606 see “Recently Issued or Adopted Accounting Pronouncements” below.

Tenant Receivables and Allowance for Uncollectible Accounts

Tenant receivables and straight-line rent receivables are carried net of the allowances for uncollectible amounts. An allowance is maintained for estimated losses resulting from the inability of certain tenants to meet the contractual obligations under their leases. Our determination of the adequacy of these allowances is based primarily upon evaluations of historical loss experience, the tenant’s financial condition, security deposits, letters of credit, lease guarantees and current economic conditions and other relevant factors. As of December 31, 2017 and 2015, we had $2.2 million in allowances for uncollectible accounts. As of December 31, 2016, we had $2.0 million in allowances for uncollectible accounts. During the year ended December 31, 2017, we recorded bad debt expense of $0.4 million. During the years ended December 31, 2016 and 2015, we recorded bad debt expense of $0.8 million

Investments in Real Estate

With the adoption of ASU 2017-01 in January 2017 we expect the majority of our future investments in real estate investments will be accounted for as asset acquisitions and to record the purchase price to tangible and intangible assets and liabilities based on their respective fair values. Tangible assets primarily consist of land and buildings and improvements. Additionally, the purchase price includes acquisition related expenses, above or below market leases, above or below market leasehold interests, in place leases, tenant relationships, above or below market debt assumed, interest rate swaps assumed and any contingent consideration recorded when the contingency is resolved. The determination of the fair value requires us to make certain estimates and assumptions.

With the assistance of independent valuation specialists, we record the purchase price of completed investments in real estate associated with tangible and intangible assets and liabilities based on their fair values. The tangible assets (land and building and improvements) are determined based upon the value of the property as if it were to be replaced or as if it were vacant using discounted cash flow models similar to those used by market participants. Factors considered by us include an estimate of carrying costs during the expected lease-up periods considering current market conditions and costs to execute similar leases. Additionally, the purchase price of the applicable completed acquisition property is inclusive of above or below market leases, above or below market leasehold interests, in place leases, tenant relationships, above or below market debt assumed, interest rate swaps assumed, any contingent consideration and acquisition related expenses.

The value of above or below market leases is determined based upon the present value (using a discount rate which reflects the risks associated with the acquired leases) of the difference between (i) the contractual amounts to be received pursuant to the lease over its remaining term and (ii) our estimate of the amounts that would be received using fair market rates over the remaining term of the lease including any bargain renewal periods. The amounts associated with above market leases are included in other intangibles, net in our accompanying consolidated balance sheets and amortized to rental income over the remaining lease term. The amounts allocated to below market leases are included in intangible liabilities, net in our accompanying consolidated balance sheets and amortized to rental income over the remaining lease term.

The value associated with above or below market leasehold interests is determined based upon the present value (using a discount rate which reflects the risks associated with the acquired leases) of the difference between: (i) the contractual amounts to be paid pursuant to the lease over its remaining term; and (ii) our estimate of the amounts that would be paid using fair market rates over the remaining term of the lease including any bargain renewal periods. The amounts recorded for above market leasehold interests are included in intangible liabilities, net in our accompanying consolidated balance sheets and amortized to rental expense over the remaining lease term. The amounts allocated to below market leasehold interests are included in other intangibles, net in our accompanying consolidated balance sheets and amortized to rental expense over the remaining lease term.

The total amount of other intangible assets includes in place leases and tenant relationships based on our evaluation of the specific characteristics of each tenant’s lease and our overall relationship with that respective tenant. Characteristics considered by us in allocating these values include the nature and extent of the credit quality and expectations of lease renewals, among other factors. The amounts recorded for in place leases and tenant relationships are included in lease intangibles in our accompanying consolidated balance sheets and will be amortized to amortization expense over the remaining lease term.

The value recorded for above or below market debt is determined based upon the present value of the difference between the cash flow stream of the assumed mortgage and the cash flow stream of a market rate mortgage. The amounts recorded for above or below market debt are included in debt in our accompanying consolidated balance sheets and are amortized to interest expense over the remaining term of the assumed debt.

The value recorded for interest rate swaps is based upon a discounted cash flow analysis on the expected cash flows, taking into account interest rate curves and the remaining term. See derivative financial instruments below for further discussion.

HEALTHCARE TRUST OF AMERICA, INC. AND HEALTHCARE TRUST OF AMERICA HOLDINGS, LP NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

The cost of operating properties includes the cost of land and buildings and related improvements. Expenditures that increase the service life of properties are capitalized and the cost of maintenance and repairs is charged to expense as incurred. The cost of buildings is depreciated on a straight-line basis over the estimated useful lives of the buildings up to 39 years and for tenant improvements, the shorter of the lease term or useful life, ranging from one month to 193 months. Furniture, fixtures and equipment is depreciated over five years. Depreciation expense of buildings and improvements for the years ended December 31, 2017, 2016 and 2015, was $172.6 million, $118.7 million and $101.2 million, respectively.

Development

We capitalize interest, direct and indirect project costs associated with the initial construction up to the time the property is substantially complete and ready for its intended use. In addition, we capitalize costs, including real estate taxes, insurance and utilities, that have been allocated to vacant space based on the square footage of the portion of the building not held available for immediate occupancy during the extended lease-up periods after construction of the building shell has been completed if costs are being incurred to ready the vacant space for its intended use. If costs and activities incurred to ready the vacant space cease, then cost capitalization is also discontinued until such activities are resumed. Once necessary work has been completed on a vacant space, project costs are no longer capitalized. We cease capitalization of all project costs on extended lease-up periods when significant activities have ceased, which does not exceed the shorter of a one-year period after the completion of the building shell or when the property attains 90% occupancy.

Real Estate Held for Sale

We consider properties as held for sale once management commits to a plan to sell the property and has determined that the sale is probable and expected to occur within one year. Upon classification as held for sale, we record the property at the lower of its carrying amount or fair value, less costs to sell, and cease depreciation and amortization. The fair value is generally based on discounted cash flow analyses, which involve management’s best estimate of market participants’ holding period, market comparables, future occupancy levels, rental rates, capitalization rates, lease-up periods and capital requirements. We did not classify any assets as held for sale for the years ended December 31, 2017, 2016 and 2015.

Recoverability of Real Estate Investments

Real Estate Notes Receivable

We evaluate the carrying values of real estate notes receivable on an individual basis. Management periodically evaluates the realizability of future cash flows from real estate notes receivable when events or circumstances, such as the non-receipt of principal and interest payments and/or significant deterioration of the financial condition of the borrower, indicate that the carrying amount of the real estate notes receivable may not be recoverable. An impairment loss is recognized in current period earnings and is calculated as the difference between the carrying amounts of the real estate notes receivable and the discounted cash flows expected to be received, or if foreclosure is probable, the fair value of the collateral securing the real estate notes receivable. For the years ended December 31, 2017, 2016 and 2015, there were no impairment losses.

Unconsolidated Joint Ventures

We account for our investments in unconsolidated joint ventures using the equity method of accounting because we have the ability to exercise significant influence, but not control, over the financial and operational policy decisions of the investments. Using the equity method of accounting, the initial investment is recognized at cost and subsequently adjusted for our share of the net income or loss and any distributions from the joint venture. As of December 31, 2017, we had a 50% interest in one such investment with a carrying value, maximum exposure to risk, of $68.6 million, which is recorded in investment in unconsolidated joint venture in the accompanying consolidated balance sheets. We record our share of net income (loss) in income (loss) from unconsolidated joint venture in the accompanying consolidated statements of operations. For the year ended December 31, 2017, we recognized income of $0.8 million. Our unconsolidated joint venture was acquired in 2017 and as such, there was no income (loss) or distributions for the years ended December 31, 2016 or 2015.

Table of Contents

HEALTHCARE TRUST OF AMERICA, INC. AND HEALTHCARE TRUST OF AMERICA HOLDINGS, LP NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

As of January 1, 2017, we adopted ASU 2016-15, as described below in “Recently Issued or Adopted Accounting Pronouncements”, which clarifies the guidance on the classification of certain cash receipts and payments in the statement of cash flows to reduce diversity in practice. As part of this adoption we have elected the cumulative earnings approach for the treatment and classification of our distributions received from our unconsolidated joint venture. As such, these distributions received from our unconsolidated joint venture will be included as a component to net cash provided by operating activities in our accompanying consolidated statements of cash flows.

Derivative Financial Instruments

We are exposed to the effect of interest rate changes in the normal course of business. We seek to mitigate these risks by following established risk management policies and procedures which include the occasional use of derivatives. Our primary strategy in entering into derivative contracts is to add stability to interest expense and to manage our exposure to interest rate movements. We utilize derivative instruments, including interest rate swaps, to effectively convert a portion of our variable rate debt to fixed rate debt. We do not enter into derivative instruments for speculative purposes. To qualify for hedge accounting, derivative financial instruments used for risk management purposes must effectively reduce the risk exposure that they are designed to hedge. In addition, at inception of a qualifying cash flow hedging relationship, the underlying transaction or transactions, must be, and are expected to remain, probable of occurring in accordance with our related assertions.

Derivatives are recognized as either assets or liabilities in our accompanying consolidated balance sheets and are measured at fair value. Changes in fair value of derivative financial instruments that are not designated in hedging relationships or that do not meet the criteria of hedge accounting are included as a component of interest expense in our accompanying consolidated statements of operations. Changes in fair value of derivative financial instruments designated in qualifying cash flow hedging relationships related to the effective portion are included in other comprehensive gain (loss) in our accompanying consolidated statements of comprehensive income (loss), whereas changes in fair value related to the ineffective portion are included as a component of interest expense in our accompanying consolidated statements of operations.

The valuation of our derivative financial instruments are determined with the assistance of an independent valuation specialist using a proprietary model that utilizes widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each derivative and observable inputs. The proprietary model reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves, foreign exchange rates and implied volatilities. The fair values of interest rate swaps are determined using the market standard methodology of netting the discounted future fixed cash payments and the discounted expected variable cash receipts. The variable cash receipts are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves.

We incorporate credit valuation adjustments to appropriately reflect both our own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of our derivative contracts for the effect of nonperformance risk, we have considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts and guarantees.

In addition, we formally document all relationships between hedging instruments and hedged items, as well as its risk-management objectives and strategy for undertaking various hedge transactions prior to or contemporaneous with entering into the derivative financial instrument. We also assess, at inception of the hedging relationship and on a quarterly basis, whether the derivative financial instruments are highly effective in offsetting the designated risks associated with the respective hedged items.

Fair Value Measurements

Fair value is a market-based measurement and is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Depending on the nature of the asset or liability, various techniques and assumptions can be used to estimate the fair value. Financial assets and liabilities are measured using inputs from three levels of the fair value hierarchy, as follows:

Level 1 — Inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that we have the ability to access at the measurement date. An active market is defined as a market in which transactions for the assets or liabilities occur with sufficient frequency and volume to provide pricing information on an ongoing basis.

Level 2 — Inputs include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active (markets with few transactions), inputs other than quoted prices that are observable for the asset or liability (i.e., interest rates, yield curves, etc.) and inputs that are derived principally from or corroborated by observable market data correlation or other means (market corroborated inputs).

Table of Contents

Level 3 — Unobservable inputs, only used to the extent that observable inputs are not available, reflect our assumptions about the pricing of an asset or liability.

We use fair value measurements to record fair value of certain assets and to estimate fair value of financial instruments not recorded at fair value but required to be disclosed at fair value.

Receivables and Other Assets

Deferred financing costs include amounts paid to lenders and others to obtain financing and are amortized to interest expense on a straight-line basis over the term of the unsecured revolving credit facility which approximates the effective interest method. Deferred leasing costs are amounts incurred in executing a lease, both for external broker and marketing costs, plus a portion of internal leasing related costs. Deferred leasing costs are amortized on a straight-line basis method over the term of the applicable lease. Deferred leasing costs are included in operating activities in our accompanying consolidated statements of cash flows.

Share-Based Compensation

We calculate the fair value of share-based awards on the date of grant. Restricted common stock is valued based on the closing price of our common stock on the NYSE. We amortize the share-based compensation expense over the period that the awards are expected to vest, net of estimated forfeitures. See Note 10 - Stockholders’ Equity and Partners’ Capital for further discussion.

Noncontrolling Interests

HTA’s net income attributable to noncontrolling interests in the accompanying consolidated statements of operations relate to both noncontrolling interest reflected within equity and redeemable noncontrolling interests reflected outside of equity in the accompanying consolidated balance sheets. OP Units, including LTIP awards, are accounted for as partners’ capital in HTALP’s accompanying consolidated balance sheets and as noncontrolling interest reflected within equity in HTA’s accompanying consolidated balance sheets.

Redeemable noncontrolling interests relate to the interests in our consolidated entities that are not wholly owned by us. As these redeemable noncontrolling interests provide for redemption features not solely within our control, we classify such interests outside of permanent equity or partners’ capital. Accordingly, we record the carrying amount at the greater of the initial carrying amount (increased or decreased for the noncontrolling interest’s share of net income or loss and distributions) or the redemption value.

Income Taxes

HTA believes that it has qualified to be taxed as a REIT under the provisions of the Code, beginning with the taxable year ending December 31, 2007 and it intends to continue to qualify to be taxed as a REIT. To continue to qualify as a REIT for federal income tax purposes, HTA must meet certain organizational and operational requirements, including a requirement to pay dividend distributions to its stockholders of at least 90% of its annual taxable income. As a REIT, HTA is generally not subject to federal income tax on net income that it distributes to its stockholders, but it may be subject to certain state or local taxes on its income and property.

If HTA fails to qualify as a REIT in any taxable year, it will then be subject to U.S. federal income taxes on our taxable income and will not be permitted to qualify for treatment as a REIT for U.S. federal income tax purposes for four years following the year during which qualification is lost unless the IRS grants it relief under certain statutory provisions. Such an event could have a material adverse effect on its business, financial condition, results of operations and net cash available for dividend distributions to its stockholders.

As discussed in Note 1 - Organization and Description of Business, HTA conducts substantially all of its operations through HTALP. As a partnership, HTALP generally is not liable for federal income taxes. The income and loss from the operations of HTALP is included in the tax returns of its partners, including HTA, who are responsible for reporting their allocable share of the partnership income and loss. Accordingly, no provision for income taxes has been made on the accompanying consolidated financial statements.

We do not have any liability for uncertain tax positions that we believe should be recognized in our accompanying consolidated financial statements. The tax basis exceeded the carrying amount of the net real estate assets reported in our accompanying consolidated balance sheet by approximately $404.1 million as of December 31, 2017.

Concentration of Credit Risk

We maintain the majority of our cash and cash equivalents at major financial institutions in the U.S. and deposits with these financial institutions may exceed the amount of insurance provided on such deposits; however, we regularly monitor the financial stability of these financial institutions and believe we are not currently exposed to any significant default risk with respect to these deposits. As of December 31, 2017, we had cash balances of $56.2 million in excess of Federal Deposit Insurance Corporation insured limits.

Segment Disclosure

We have determined that we have one reportable segment, with activities related to investing in healthcare real estate assets. Our investments in healthcare real estate assets are geographically diversified and our chief operating decision maker evaluates operating performance on an individual asset level. As each of our assets has similar economic characteristics, long-term financial performance, tenants, and products and services, our assets have been aggregated into one reportable segment.

Recently Issued or Adopted Accounting Pronouncements

The following table provides a brief description of recently adopted accounting pronouncements:



Accounting Pronouncement	Description	Effective Date	Effect on financial statements
ASU 2017-01 Business Combinations: Clarifying the Definition of a Business (Issued January 2017)	ASU 2017-01 clarifies the definition of a business by adding guidance to assist entities evaluate whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The definition of a business affects many areas of accounting, including, but not limited to, acquisitions, disposals, goodwill and consolidation.	ASU 2017-01 is effective for fiscal years beginning after December 15, 2017 with early adoption permitted.	We adopted ASU 2017-01 as of January 1, 2017 on a prospective basis. We expect that the majority of our future investments in real estate will be accounted for as asset acquisitions under ASU 2017-01. The adoption of ASU 2017-01 will impact how we account for acquisition-related expenses and contingent consideration, which may result in lower acquisition-related expenses and eliminate fair value adjustments related to future contingent consideration arrangements.
ASU 2016-15 Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments (Issued August 2016)	ASU 2016-15 clarifies the guidance on the classification of certain cash receipts and payments in the statement of cash flows to reduce diversity in practice with respect to: (i) debt prepayment or debt extinguishment costs; (ii) settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; (iii) contingent consideration payments made after a business combination; (iv) proceeds from the settlement of insurance claims; (v) proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies; (vi) distributions received from equity method investees; (vii) beneficial interests in securitization transactions; and (viii) separately identifiable cash flows and application of the predominance principle.	ASU 2016-15 is effective for fiscal years beginning after December 15, 2017 with early adoption permitted.	We adopted ASU 2016-15 as of January 1, 2017 and applied the standard retrospectively for all periods presented. Based on our final assessment we have determined that the presentation of debt prepayments or debt extinguishment costs and distributions from equity method investments are directly applicable to us. Debt prepayments or debt extinguishment costs are currently classified as a component to net cash used by financing activities in our accompanying statements of cash flows and will continue to be recorded as such. As part of the adoption, we have elected the cumulative earnings approach for the treatment and classification of distributions received from unconsolidated joint venture. These distributions will be reported as a component to net cash provided by operating activities in our accompanying consolidated statements of cash flows. There will be no reclassifications or material impacts on our consolidated financial statements as a result of this adoption.
ASU 2016-18 Statement of Cash Flows: Restricted Cash (Issued November 2016)	ASU 2016-18 requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows.	ASU 2016-18 is effective for fiscal years beginning after December 15, 2017 with early adoption permitted.	We adopted ASU 2016-18 as of January 1, 2017 and applied the standard retrospectively for all periods presented. Restricted cash and escrow deposits consist primarily of cash escrowed for real estate acquisitions, real estate taxes, property insurance and capital improvements. We will provide a reconciliation of the changes in cash, cash equivalents and restricted cash within our accompanying consolidated balance sheets to the consolidated statement of cash flows. We will also provide a reclassification disclosure for the movement of restricted cash out of cash flows from investing activities.

The following table provides a brief description of recently issued accounting pronouncements:



Accounting Pronouncement	Description	Effective Date	Effect on financial statements
Topic 606; collectively, ASU 2014-09, 2015-14, ASU 2016-08, ASU 2016-10, ASU 2016-11, ASU 2016-12, ASU 2016-20, ASU 2017-05, ASU 2017-10, ASU 2017-13 and ASU 2017-14 Revenue from Contracts with Customers (Issued May 2014, August 2015, March 2016, April 2016, May 2016, December 2016, February 2017, May 2017, September 2017 and November 2017)	In May 2014, the FASB issued Topic 606. The objective of Topic 606 is to establish a comprehensive new five-step model requiring a company to recognize revenue to depict the transfer of goods or services to customers in amounts that reflect the consideration (i.e., payment) to which the company expects to be entitled in exchange for those goods or services. Expanded quantitative and qualitative disclosures regarding revenue recognition will be required for contracts that are subject to Topic 606. Topic 606 does not apply to revenue from lease contracts until the adoption of the new leases standard in ASU 2016-02, in January 2019. ASU 2017-05 applies to all nonfinancial assets (including real estate) for which the counterparty is not a customer and requires an entity to derecognize a nonfinancial asset in a partial sale transaction when it ceases to have a controlling financial interest in the asset and has transferred control of the asset. Once an entity transfers control of the nonfinancial asset, the entity is required to measure any nonconrolling interest it receives or retains at fair value. Under the current guidance, a partial sale is recognized and carryover basis is used for the retained interest resulting in only partial gain recognition by the entity, however, the new guidance eliminates the use of carryover basis and generally requires the full gain to be recognized. In adopting Topic 606, companies may use either a full retrospective or a modified retrospective approach.	Topic 606 is effective for fiscal years beginning after December 15, 2017 along with the right of early adoption as of the original effective date.	We have identified all of our revenue streams and concluded rental income from leasing arrangements represents a substantial portion of our revenue and is specifically excluded from Topic 606 and will be governed and evaluated with the anticipated adoption of ASU 2016-02 as described below. Upon adoption of ASU 2016-02, Topic 606 may apply to executory costs and other components of revenue due under leases that are deemed to be non-lease components (such as common area maintenance and other reimbursement revenue), even when the revenue for such activities is not separately stipulated in the lease. In that case, the revenue from these items previously recognized on a straight-line basis under the current lease guidance would be recognized under the new revenue guidance as the related services are delivered. As a result, while total revenue recognized over time would not differ under the new guidance, the recognition pattern would be different. Under Topic 606, revenue recognition for real estate sales is largely based on the transfer of control versus continuing involvement under the current guidance. Upon adoption, there will not be a material impact on our consolidated financial statements since we have historically disposed of the majority of our properties with no future controls or contingencies. We will adopt Topic 606 effective January 1, 2018 using the modified retrospective approach.
ASU 2016-02 Leases (Issued February 2016)	ASU 2016-02 will supersede the existing guidance for lease accounting and states that companies will be required to recognize lease assets and lease liabilities on the balance sheet and disclose key information about leasing arrangements. ASU 2016-02 requires qualitative and quantitative disclosures to supplement the amounts recorded in the financial statements so that users can understand the nature of the entity’s leasing activities, including significant judgments and changes in judgments. Within ASU 2016-02 lessor accounting remained fairly unchanged. In adopting ASU 2016-02, companies will be required to use a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements.	ASU 2016-02 is effective for the fiscal years beginning after December 15, 2018 with early adoption permitted.	We are still evaluating the full impact of ASU 2016-02 on our consolidated financial statements, however, we will adopt ASU 2016-02 as of January 1, 2019 and anticipate that we will elect a practical expedient offered in ASU 2016-02 that allows an entity to not reassess the following upon adoption (elected as a group): (i) whether an expired or existing contract contains a lease arrangement; (ii) lease classification related to expired or existing lease arrangements; or (iii) whether costs incurred on expired or existing leases qualify as initial direct costs. As a result of the adoption, all leases for which we are the lessee, including corporate and ground leases will be recorded on our consolidated financial statements as either financing leases or operating leases with a related right of use asset and lease liability. In addition, we expect that certain executory and non-lease components, such as common area maintenance, will need to be accounted for separately from the lease component of the lease. Lease components will continue to be recognized on a straight-line basis over the lease term and certain non-lease components will be accounted for under the new revenue recognition guidance in Topic 606 as mentioned above.
ASU 2016-13 Financial Instruments Credit Losses: Measurement of Credit Losses on Financial Instruments (Issued June 2016)	ASU 2016-13 is intended to improve financial reporting by requiring more timely recognition of credit losses on loans and other financial instruments that are not accounted for at fair value through net income, including loans held for investment, held-to-maturity debt securities, trade and other receivables, net investment in leases and other such commitments. ASU 2016-13 requires that financial statement assets measured at an amortized cost be presented at the net amount expected to be collected through an allowance for credit losses that is deducted from the amortized cost basis.	ASU 2016-13 is effective for fiscal years beginning after December 15, 2019 with early adoption permitted.	We do not anticipate early adoption or there to be a material impact, however, we are evaluating the impact of adopting ASU 2016-13 on our consolidated financial statements.

Accounting Pronouncement	Description	Effective Date	Effect on financial statements
ASU 2017-09 Compensation - Stock Compensation (Topic 718): Clarifying the Scope of Modification (Issued May 2017)	ASU 2017-09 amends the scope of modification accounting for share-based payment arrangements and provides guidance on the types of changes to the terms and conditions of share-based payment awards to which an entity would be required to apply modification accounting under ASC 718.	ASU 2017-09 is effective for fiscal years beginning after December 15, 2017 with early adoption permitted.	We will adopt ASU 2017-09 as of January 1, 2018. We do not anticipate there to be a material impact on our consolidated financial statements.
ASU 2017-12 Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities (Issued August 2017)	ASU 2017-12 expands and refines hedge accounting for both financial (e.g., interest rate) and non-financial risk components, aligns the recognition and presentation of the effects of hedging instruments and hedge items in the financial statements, and includes certain targeted improvements to ease the application of current guidance related to the assessment of hedge effectiveness.	ASU 2017-12 is effective for fiscal years beginning after December 15, 2018 with early adoption permitted.	We do not anticipate early adoption, however, we are evaluating the impact of adopting ASU 2017-12 on our consolidated financial statements.

3. Investments in Real Estate

Our investments, including the Duke Acquisition, brings our total investments for the year ended December 31, 2017 to an aggregate purchase price of $2.7 billion.

Unsecured Credit Agreement

Unsecured Revolving Credit Facility due 2022

On July 27, 2017, HTALP entered into an amended and restated $1.3 billion Unsecured Credit Agreement which increased the amount available under the unsecured revolving credit facility to $1.0 billion and extended the maturities of the unsecured revolving credit facility to June 30, 2022 and for the $300.0 million unsecured term loan referenced below until February 1, 2023. The maximum principal amount of the Unsecured Credit Agreement may be increased by up to $750.0 million, subject to certain conditions, for a total principal amount of $2.05 billion.

Borrowings under the unsecured revolving credit facility accrue interest at a rate equal to adjusted LIBOR, plus a margin ranging from 0.83% to 1.55% per annum based on our credit rating. We also pay a facility fee ranging from 0.13% to 0.30% per annum on the aggregate commitments under the unsecured revolving credit facility. As of December 31, 2017, the margin associated with our borrowings was 1.00% per annum and the facility fee was 0.20% per annum.

Unsecured Term Loan due 2023

On July 27, 2017, we entered into an amended and restated Unsecured Credit Agreement as noted above. As part of this agreement, we obtained a $300.0 million unsecured term loan that was guaranteed by us with a maturity date of February 1, 2023. Borrowings under this unsecured term loan accrue interest equal to adjusted LIBOR, plus a margin ranging from 0.90% to 1.75% per annum based on our credit rating. The margin associated with our borrowings as of December 31, 2017 was 1.10% per annum. Including the impact of the interest rate swaps associated with our unsecured term loan, the interest rate was 2.71% per annum, based on our current credit rating. As of December 31, 2017, HTALP had $300.0 million under this unsecured term loan outstanding.

Bridge Loan Facility

In connection with the Duke Acquisition, in May 2017, we entered into the Bridge Loan Facility which provided to us up to $2.47 billion, less the aggregate amount of net proceeds from debt or equity capital raises or a senior term loan facility. The Bridge Loan Facility was made available to us on the closing of the Duke Acquisition and was scheduled to mature 364 days from the closing. In June 2017, we terminated the Bridge Loan Facility and no proceeds were used because we elected to fund the Duke Acquisition through other equity and debt offerings. In connection with the execution and subsequent termination of the Bridge Loan Facility, we incurred $10.4 million in related fees, which we recorded in income (loss) on extinguishment of debt in the accompanying consolidated statements of operations.

$200.0 Million Unsecured Term Loan due 2023

As of December 31, 2017, HTALP had a $200.0 million unsecured term loan outstanding, which matures on September 26, 2023. Borrowings under the unsecured term loan accrue interest at a rate equal to LIBOR, plus a margin ranging from 1.50% to 2.45% per annum based on our credit rating. The margin associated with our borrowings as of December 31, 2017 was 1.65% per annum. HTALP had interest rate swaps in place that fixed the interest rate at 3.07% per annum, based on our current credit rating.

We are required by the terms of our applicable loan agreements to meet various affirmative and negative covenants that we believe are customary for these types of facilities, such as limitations on the incurrence of debt by us and our subsidiaries that own unencumbered assets, limitations on the nature of HTALP’s business, and limitations on distributions by HTALP and its subsidiaries that own unencumbered assets. Our loan agreements also impose various financial covenants on us, such as a maximum ratio of total indebtedness to total asset value, a minimum ratio of EBITDA to fixed charges, a minimum tangible net worth covenant, a maximum ratio of unsecured indebtedness to unencumbered asset value, rent coverage ratios and a minimum ratio of unencumbered NOI to unsecured interest expense. As of December 31, 2017, we believe that we were in compliance with all such financial covenants and reporting requirements. In addition, certain of our loan agreements include events of default provisions that we believe are customary for these types of facilities, including restricting us from making dividend distributions to our stockholders in the event we are in default thereunder, except to the extent necessary for us to maintain our REIT status.

8. Derivative Financial Instruments and Hedging Activities

Risk Management Objective of Using Derivative Financial Instruments

We may use derivative financial instruments, including interest rate swaps, caps, options, floors and other interest rate derivative contracts, to hedge all or a portion of the interest rate risk associated with our borrowings. The principal objective of such arrangements is to minimize the risks and/or costs associated with our operating and financial structure as well as to hedge specific anticipated transactions. We do not intend to utilize derivatives for speculative or other purposes other than interest rate risk management. The use of derivative financial instruments carries certain risks, including the risk that the counterparties to these contractual arrangements are not able to perform under the agreements. To mitigate this risk, we only enter into derivative financial instruments with counterparties with high credit ratings and with major financial institutions with which we and our affiliates may also have other financial relationships. We do not anticipate that any of the counterparties will fail to meet their obligations. We record counterparty credit risk valuation adjustments on interest rate swap derivative assets in order to properly reflect the credit quality of the counterparty. In addition, our fair value of interest rate swap derivative liabilities is adjusted to reflect the impact of our credit quality.

Cash Flow Hedges of Interest Rate Risk

Our objectives in using interest rate derivatives are to add stability to interest expense and to manage our exposure to interest rate movements. To accomplish this objective, we primarily use interest rate swaps and treasury locks as part of our interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable rate amounts from a counterparty in exchange for us making fixed rate payments over the life of the agreements without exchange of the underlying notional amount. A treasury lock is a synthetic forward sale of a U.S. treasury note, which is settled in cash based upon the difference between an agreed upon treasury rate and the prevailing treasury rate at settlement. Such treasury locks are entered into to effectively fix the treasury component of an upcoming debt issuance.

The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive income in the accompanying consolidated balance sheets and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. During the year ended December 31, 2017, such derivatives were used to hedge the variable cash flows associated with variable rate debt. The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings. During the year ended December 31, 2017, we recorded approximately $43,000 of hedge ineffectiveness in earnings. We designated our derivative financial instruments as cash flow hedges in March 2017 as such there was no hedge ineffectiveness in earnings for the years ended December 31, 2016.

During the year ended December 31, 2017, we entered into and settled two treasury locks designated as cash flow hedges with an aggregate notional amount of $250.0 million to hedge future fixed rate debt issuances, which fixed the 10-year swap rates at an average rate of 2.26% per annum. Upon settlement of these contracts during the year ended December 31, 2017, we paid and reported a loss of $0.7 million which was recorded in accumulated other comprehensive loss in our accompanying consolidated statements of comprehensive income (loss) and a gain of $25,000 which was recorded in the change in fair value of our derivative financial instruments in our accompanying consolidated statements of operations.

Amounts reported in accumulated other comprehensive income in the accompanying consolidated balance sheets related to derivatives will be reclassified to interest expense as interest payments are made on our variable rate debt. During the next twelve months, we estimate that an additional $0.2 million will be reclassified from other comprehensive income in the accompanying consolidated balance sheets as an increase to interest related to derivative financial instruments in the accompanying consolidated statements of operations.

As of December 31, 2017, we had the following outstanding interest rate derivatives that were designated as cash flow hedges of interest rate risk (in thousands, except number of instruments):

Non-Designated Hedges

Derivatives not designated as hedges are not speculative and are used to manage our exposure to interest rate movements and other identified risks, but do not meet the strict hedge accounting requirements of ASC 815 - Derivatives and Hedging. Changes in the fair value of derivatives not designated in hedging relationships are recorded directly in earnings. Changes in the fair value of derivatives not designated in hedging relationships are recorded directly to gain or loss on change in fair value of derivative financial instruments in the accompanying consolidated statements of operations. For the years ended December 31, 2017 and 2016, we recorded a gain on change in fair value of derivative financial instruments of $0.9 million and $1.3 million, respectively.

Credit Risk Related Contingent Features

We have agreements with each of our derivative counterparties that contain a provision that if we default on any of our indebtedness, including a default where repayment of the indebtedness has not been accelerated by the lender, then we could also be declared in default on our derivative obligations.

We also have agreements with each of our derivative counterparties that incorporate provisions from our indebtedness with a lender affiliate of the derivative counterparty requiring it to maintain certain minimum financial covenant ratios on our indebtedness. Failure to comply with the covenant provisions would result in us being in default on any derivative instrument obligations covered by these agreements.

As of December 31, 2017, the fair value of derivatives in a net liability position, including accrued interest, but excluding any adjustment for nonperformance risk related to these agreements, was $1.1 million. As of December 31, 2017, we have not posted any collateral related to these agreements and we were not in breach of any of the provisions of these agreements. If we had breached any of the provisions of these agreements, we could have been required to settle our obligations under these agreements at an aggregate termination value of $1.1 million at December 31, 2017.

9. Commitments and Contingencies

Litigation

We engage in litigation from time to time with various parties as a routine part of our business, including tenant defaults. However, we are not presently subject to any material litigation nor, to our knowledge, is any material litigation threatened against us, which if determined unfavorably to us, would have a material effect on our consolidated financial position, results of operations or cash flows.

Environmental Matters

We follow the policy of monitoring our properties for the presence of hazardous or toxic substances. While there can be no assurance that a material environmental liability does not exist at our properties, we are not currently aware of any environmental liability with respect to our properties that would have a material effect on our consolidated financial position, results of operations or cash flows. Further, we are not aware of any material environmental liability or any unasserted claim or assessment with respect to an environmental liability at our properties that we believe would require additional disclosure or the recording of a loss contingency.

Rental Expense

We have ground leases and other operating leases with landlords that generally require fixed annual rental payments and may also include escalation clauses and renewal options. These leases generally have terms up to 99 years, excluding extension options. Future minimum lease obligations under non-cancelable ground leases and other operating leases as of December 31, 2017 are as follows (in thousands):



Year	Amount
2018	$	10,908
2019	11,035
2020	11,177
2021	11,332
2022	11,566
Thereafter	916,180
Total	$	972,198

HEALTHCARE TRUST OF AMERICA, INC. AND HEALTHCARE TRUST OF AMERICA HOLDINGS, LP NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

During the years ended December 31, 2017, 2016 and 2015, rental expense was $11.5 million, $8.5 million and $6.9 million, respectively. The amount of contingent rent and sublease rent was not significant.

Other

Our other commitments and contingencies include the usual obligations of real estate owners and operators in the normal course of business. In our opinion, these matters are not expected to have a material effect on our consolidated financial position, results of operations or cash flows.

10. Stockholders’ Equity and Partners’ Capital

HTALP’s operating partnership agreement provides that it will distribute cash flow from operations and net sale proceeds to its partners in accordance with their overall ownership interests at such times and in such amounts as the general partner determines. Dividend distributions are made such that a holder of one OP Unit in HTALP will receive distributions from HTALP in an amount equal to the dividend distributions paid to the holder of one share of our common stock. In addition, for each share of common stock issued or redeemed by us, HTALP issues or redeems a corresponding number of OP Units.

During the year ended December 31, 2017, we issued $1.8 billion of equity at an average price of $28.76 per share and entered a forward sale arrangement pursuant to a forward equity agreement, with anticipated net proceeds of $75.0 million to be settled in April 2018, subject to adjustments as provided in the forward equity agreement. Refer to Note 12 - Per Share Data of HTA to these consolidated financial statements for a more detailed discussion related to our forward equity agreement executed in October 2017.

Common Stock Offerings

In September 2017, we entered into new equity distribution agreements with our various sales agents with respect to our ATM offering program of common stock with an aggregate sales amount of up to $500.0 million. In October 2017, we issued 4,200,000 shares of our common stock for $124.3 million of gross proceeds at a price of $29.60 per share, and the $75.0 million forward contract which will be issued over the next six months. We contemporaneously terminated our prior ATM equity distribution agreements. Additionally, during the year ended December 31, 2017, and under the previous ATM, we issued and sold 3,998,000 shares of our common stock for $125.7 million of gross proceeds at an average price of $31.45 per share. As of December 31, 2017, $300.7 million remained available for issuance by us under the September 2017 ATM.

During the year ended December 31, 2017, we, in connection with the Duke Acquisition, completed an underwritten public offering of 54,625,000 shares of our common stock for $1.6 billion of gross proceeds at a price of $28.50 per share.

Common Unit Offerings

During the year ended December 31, 2017, we issued 37,659 OP Units in HTALP for approximately $1.1 million in connection with acquisition transactions.

Common Stock Dividends

See our accompanying consolidated statements of operations for the dividends declared during the years ended December 31, 2017, 2016 and 2015. On February 15, 2018, our Board of Directors announced a quarterly dividend of $0.305 per share/unit of common stock to be paid on April 10, 2018 to stockholders of record of our common stock and OP unitholders on April 3, 2018.

Incentive Plan

The Plan permits the grant of incentive awards to our employees, officers, non-employee directors and consultants as selected by our Board of Directors. The Plan authorizes us to grant awards in any of the following forms: options; stock appreciation rights; restricted stock; restricted or deferred stock units; performance awards; dividend equivalents; other stock-based awards, including units in HTALP; and cash-based awards. Subject to adjustment as provided in the Plan, the aggregate number of awards reserved and available for issuance under the Plan is 5,000,000 shares. As of December 31, 2017, there were 1,693,510 awards available for grant under the Plan.

HEALTHCARE TRUST OF AMERICA, INC. AND HEALTHCARE TRUST OF AMERICA HOLDINGS, LP NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

LTIP Units

Awards under the LTIP consist of Series C units in HTALP and were subject to the achievement of certain performance and market conditions in order to vest. Once vested, the Series C units were converted into common units of HTALP, which may be converted into shares of our common stock. The LTIP awards were fully expensed or forfeited in 2015.

Restricted Common Stock

The weighted average fair value of restricted common stock granted during the years ended December 31, 2017, 2016 and 2015 was $29.75, $29.82 and $26.52, respectively. The fair value of restricted common stock for which the restriction lapsed during the years ended December 31, 2017, 2016 and 2015 were $5.9 million, $5.4 million and $4.6 million, respectively.

We recognized compensation expense, equal to the fair market value of HTA’s stock on the grant date, over the service period which is generally three to four years. For the years ended December 31, 2017, 2016, and 2015, we recognized compensation expense of $6.9 million, $7.1 million and $5.7 million, respectively. Compensation expense was recorded in general and administrative expenses in the accompanying consolidated statements of operations.

As of December 31, 2017, we had $7.9 million of unrecognized compensation expense, net of estimated forfeitures, which we will recognize over a remaining weighted average period of 1.6 years.

The following is a summary of our restricted common stock activity as of December 31, 2017 and 2016, respectively:



	December 31, 2017				December 31, 2016

MOB⁽¹⁾	$	—	$	10,271	$	—	$	10,271

(1) During the year ended December 31, 2017, we recognized $13.9 million of impairment charges to the carrying value of two MOBs and a portfolio of MOBs. The estimated fair value as of December 31, 2017 for these MOBs was based upon a pending sales agreement and real estate market comparables.

The table below presents our assets measured at fair value on a non-recurring basis as of December 31, 2016, aggregated by the applicable level in the fair value hierarchy (in thousands):



	Level 1		Level 2		Level 3		Total
Assets:
MOB⁽¹⁾	$	—	$	8,191	$	—	$	8,191

(1) During the year ended December 31, 2016, we recognized impairment charges of $1.3 million and $1.8 million to the carrying value of two MOBs. The estimated fair value as of December 31, 2016 for these two MOBs was based upon a pending sales agreement and real estate market comparables.

There have been no transfers of assets or liabilities between levels. We will record any such transfers at the end of the reporting period in which a change of event occurs that results in a transfer. Although we have determined that the majority of the inputs used to value our interest rate swap derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with these instruments utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by us and our counterparties. However, we have assessed the significance of the impact of the credit valuation adjustments on the overall valuation of our interest rate swap derivative positions and have determined that the credit valuation adjustments are not significant to their overall valuation. As a result, we have determined that our interest rate swap derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy.

Financial Instruments Disclosed at Fair Value

We consider the carrying values of cash and cash equivalents, tenant and other receivables, restricted cash and accounts payable, and accrued liabilities, to approximate fair value for these financial instruments because of the short period of time between origination of the instruments and their expected realization. All of these financial instruments are considered Level 2.

The fair value of debt is estimated using borrowing rates available to us with similar terms and maturities, which is considered a Level 2 input. As of December 31, 2017, the fair value of the debt was $2,826.3 million compared to the carrying value of $2,781.0 million. As of December 31, 2016, the fair value of the debt was $1,784.0 million compared to the carrying value of $1,768.9 million.

12. Per Share Data of HTA

In October 2017, we entered a forward sale arrangement pursuant to a forward equity agreement to sell approximately 2.6 million shares of common stock through our ATM at a price of $29.40 per share, for anticipated proceeds of approximately $75 million to be settled in April 2018, subject to adjustments as provided in the forward equity agreement. To account for the forward equity agreement, we considered the accounting guidance governing financial instruments and derivatives and concluded that our forward equity agreement was not a liability as it did not embody obligations to repurchase our shares of common stock nor did it embody obligations to issue a variable number of shares for which the monetary value was predominately fixed, varying with something other than the fair value of the shares, or varying inversely in relation to our shares. We also evaluated whether the agreement met the derivatives and hedging guidance scope exception to be accounted for as an equity instrument and concluded that the agreement can be classified as an equity contract based on the following assessment: (i) none of the agreements’ exercise contingencies were based on observable markets or indices besides those related to the market for our own stock price and operations; and (ii) none of the settlement provisions precluded the agreement from being indexed to our own common stock.

HEALTHCARE TRUST OF AMERICA, INC. AND HEALTHCARE TRUST OF AMERICA HOLDINGS, LP NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

In addition, we considered the potential dilution resulting from the forward equity agreement on our earnings per common share calculations. We use the treasury method to determine the dilution resulting from the forward equity agreement during the period of time prior to settlement. The number of weighted-average shares outstanding - diluted used in the computation of earnings per common share for the year ended December 31, 2017, includes the effect from the assumed issuance of 2.6 million shares of common stock pursuant to the settlement of the forward equity agreement at the contractual price, less the assumed repurchase of common shares at the average market price using the anticipated proceeds of approximately $75.0 million, adjusted as provided for in the forward equity agreement. The impact to our weighted-average shares - diluted for the year ended December 31, 2017, was 17,000, weighted-average incremental shares.

We include unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents as “participating securities” pursuant to the two-class method. The resulting classes are our common stock and restricted stock. Our forward equity agreement is not considered a participating security and, therefore, is not included in the computation of earnings per share using the two-class method. For the years ended December 31, 2017, 2016 and 2015, all of our earnings were distributed and the calculated earnings per share amount would be the same for all classes.

The following is the reconciliation of the numerator and denominator used in basic and diluted earnings per share of HTA for the years ended December 31, 2017, 2016 and 2015, respectively (in thousands, except per share data):

16. Future Minimum Rent

We have operating leases with tenants that expire at various dates through 2043 which generally include fixed increases or adjustments based on the consumer price index. Leases also provide for additional rents based on certain operating expenses. Future minimum rent contractually due under operating leases, excluding tenant reimbursements of certain costs, as of December 31, 2017 is as follows (in thousands):



Year	Amount
2018	$	512,216
2019	474,815
2020	425,433
2021	380,282
2022	323,142
Thereafter	1,418,110
Total	$	3,533,998

A certain amount of our rental income is from tenants with leases which are subject to contingent rent provisions. These contingent rents are subject to the tenant achieving periodic revenues in excess of specified levels. For the years ended December 31, 2017, 2016 and 2015, the amount of contingent rent earned by us was not significant.
