Explanatory Note
This Quarterly Report combines the Quarterly Reports on Form 10-Q (“Quarterly Report”) for the quarter ended March 31,September 30, 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 Quarterly 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 March 31,September 30, 2017, HTA owned a 97.0%98.0% 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 inas 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.units (“OP Units”).
Noncontrolling interests, stockholders’ equity and partners’ capital are the primary areas of difference between the condensed consolidated financial statements of HTA and HTALP. Limited partnership units in HTALP are accounted for as partners’ capital in HTALP’s condensed consolidated balance sheets and as noncontrolling interest reflected within equity in HTA’s condensed 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.
The Company believesWe believe combining the Quarterly Reports of HTA and HTALP, including the notes to the condensed consolidated financial statements, into this single Quarterly 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 Quarterly Report applies to both HTA and HTALP; and
creates time and cost efficiencies through the preparation of a single combined Quarterly Report instead of two separate Quarterly Reports.
In order to highlight the material differences between HTA and HTALP, this Quarterly Report includes sections that separately present and discuss areas that are materially different between HTA and HTALP, including:
the condensed consolidated financial statements;
certain accompanying notes to the condensed consolidated financial statements, including Note 7 - Debt, Note 10 - Stockholders’ Equity and Partners’ Capital, Note 12 - Per Share Data of HTA and Note 13 - Per Unit Data of HTALP;
the Funds From Operations (“FFO”) and Normalized FFO in Part 1, Item 2 of this Quarterly Report;
the Controls and Procedures in Part 1, Item 4 of this Quarterly Report; and
the Certifications of the Chief Executive Officer and the Chief Financial Officer included as Exhibits 31 and 32 to this Quarterly Report.
In the sections of this Quarterly Report that combine disclosure for HTA and HTALP, this Quarterly 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.

NOTES TO UNAUDITED CONDENSED 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 March 31,September 30, 2017, HTA owned a 97.0%98.0% partnership interest and other limited partners, including some of HTA’sour 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 one of the largest publicly-traded REITsREIT focused on medical office buildings (“MOBs”) in the U.S. as measured by the gross leasable area (“GLA”) of itsour 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 property management and leasing platform to generate strong tenant 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 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 $4.3$7.0 billion to create a portfolio of MOBs and other healthcare assets consisting of approximately 17.824.2 million square feet of GLA throughout the U.S. As of March 31,September 30, 2017, our portfolio included $2.24 billion of investments, net of development credits received at closing, in connection with our acquisition of the Duke MOB business (the “Duke Acquisition”), which includes a 50% ownership interest in an unconsolidated joint venture for $68.8 million as of the date of acquisition. Our only remaining obligations related to the Duke Acquisition are the potential acquisition of a land parcel in Miami, FL and a single property in Texas that are each currently excluded from our purchase obligations due to current outstanding physical condition issues.
As of September 30, 2017, approximately 96% of our portfolio, based on GLA, was located on the campuses of, or aligned with, nationally or regionally recognized healthcare systems. Our portfolio is diversified geographically across 3133 states, with no state having more than 13%19% of our total GLA as of March 31,September 30, 2017. We are concentrated in 1520 to 2025 key markets that are experiencing higher economic and demographic trends than other markets, on average, that we expect will drive demand for MOBs. Approximately 92% of our portfolio, based on GLA, is located in the top 75 metropolitan statistical areas (“MSAs”) with Atlanta, Boston, Hartford/New Haven, Dallas, Houston Phoenix and Orange County/Los AngelesTampa 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

Interim Unaudited Financial Data
Our accompanying condensed consolidated financial statements have been prepared by us in accordance with GAAP in conjunction with the rules and regulations of the SEC. Certain information and footnote disclosures required for annual financial statements have been condensed or excluded pursuant to SEC rules and regulations. Accordingly, our accompanying condensed consolidated financial statements do not include all information and footnotes required by GAAP for complete financial statements. Our accompanying condensed consolidated financial statements reflect all adjustments, which are, in our opinion, of a normal recurring nature and necessary for a fair presentation of our financial position, results of operations and cash flows for the interim periods. Interim results of operations are not necessarily indicative of the results to be expected for the full year; such results may be less favorable for the full year. Our accompanying condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements and the notes thereto included in our 2016 Annual Report on Form 10-K.
Principles of Consolidation
The consolidated financial statements include ourthe accounts of those 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 limited partner unitsOP Units in HTALP (“OP Units”).HTALP. Holders of OP Units are considered to be non-controllingnoncontrolling 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 non-controllingnoncontrolling 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 sharesstock issued and the carrying value of the OP Units converted to common stock is recorded as a component of equity. As of March 31,September 30, 2017 and December 31, 2016, there were approximately 4.1 million and 4.3 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. OurThe HTALP operating partnership (HTALP) 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.
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 September 30, 2017, we had a 50% interest in one such investment with a carrying value, maximum exposure to risk, of $68.3 million, which is recorded in investment in unconsolidated joint venture in the accompanying condensed consolidated balance sheets. We record our share of net income (loss) in income (loss) from unconsolidated joint venture in the accompanying condensed consolidated statements of operations. For the three and nine months ended September 30, 2017, we recognized income of $318,000 and $381,000, respectively, from our unconsolidated joint venture.
Investments in Real Estate
Depreciation expense of buildings and improvements for the three months ended March 31,September 30, 2017 and 2016 was $32.7$49.8 million and $25.7$31.1 million, respectively. Depreciation expense of buildings and improvements for the nine months ended September 30, 2017 and 2016 was $121.5 million and $86.6 million, respectively.

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

Revenue from Contracts with Customers
(Issued May 2014)
 
ASU 2014-09 is a comprehensive new revenue recognitionfive-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 ASU 2014-09. In adopting ASU 2014-09, companies may use either a full retrospective or a modified retrospective approach.

 
In JulyAugust 2015, the FASB deferred the effective date of ASU 2014-09 to the first interim period within annual reporting periods 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 ASU 2014-09 and will be governed and evaluated with the anticipated adoption of ASU 2016-02 as described below. Upon adoption of ASU 2016-02, ASU 2014-09 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 processlease. 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 ASU 2014-09, revenue recognition for real estate sales is largely based on the transfer of evaluatingcontrol versus continuing involvement under the current guidance. Upon adoption, there will not be a material impact on our consolidated financial statements and internal accounting processes; however,since we have historically disposed of the majority of our revenues are derived from real estate lease contracts, as discussed in relation to ASU 2016-02 below.properties with no future controls or contingencies. We will adopt ASU 2014-09 effective January 1, 2018 using the modified retrospective approach and the adoption is not expected to have a material impact on our consolidated financial statements.

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 using the modified retrospective approach.  We are currently evaluating the full impact ofand 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 new or amended leases for which we are the lessee, including corporate and ground leases, that are entered into on or after January 1, 2019, will havebe recorded on our consolidated financial statements as either financing leases or operating leases with a related right of use asset and disclosures, however, we anticipate there to be a significant increase in our assets and liabilities on our consolidated balance sheets due to the recognition of our current ground leases which represented rental expense of $7.6 million and have an average remaining term of 48.2 years for the year ended December 31, 2016.lease liability. In addition, we anticipate thereexpect 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 material impact on our consolidated balance sheets and statements of operations as certain leasing costs will no longer qualify for capitalizationstraight-line basis over the life of the lease but insteadterm and certain non-lease components will be required to be expensedaccounted for under the new revenue recognition guidance in ASU 2014-09 as incurred.    mentioned above.

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. As

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 condensed consolidated balance sheets and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. During the three and nine months ended March 31,September 30, 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 three and nine months ended March 31,September 30, 2017, we recorded approximately $6,000$4,000 and $31,000, respectively, of hedge ineffectiveness in earnings. We designated our derivative financial instruments as cash flow hedges in March 2017.
During the nine months ended September 30, 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 nine months ended September 30, 2017, we paid and reported a loss of $0.7 million which was recorded in accumulated other comprehensive loss in our accompanying condensed 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 condensed consolidated statements of operations.
Amounts reported in accumulated other comprehensive income in the accompanying condensed 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 $0.7$0.4 million will be reclassified from other comprehensive income in the accompanying condensed consolidated balance sheets as an increase to interest related to derivative financial instruments in the accompanying condensed consolidated statements of operations.
As of March 31,September 30, 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):

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 escrow deposits 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 March 31,September 30, 2017, the fair value of the debt was $1,831.7$2,913.3 million compared to the carrying value of $1,811.2$2,856.8 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.

Such statements include, in particular, statements about our plans, strategies, prospects and estimates regarding future MOB market performance. Additionally, such statements are subject to certain risks and uncertainties, as well as known and unknown risks, which could cause actual results to differ materially and in adverse ways from those projected or anticipated. Therefore, such statements are not intended to be a guarantee of our performance in future periods. Forward-looking statements are generally identifiable by the use of such terms as “expect,” “project,” “may,” “should,” “could,” “would,” “intend,” “plan,” “anticipate,” “estimate,” “believe,” “continue,” “opinion,” “predict,” “potential,” “pro forma” or the negative of such terms and other comparable terminology.

Any such forward-looking statements reflect our current views about future events, are subject to unknown risks, uncertainties, and other factors, and are based on a number of assumptions involving judgments with respect to, among other things, future economic, competitive and market conditions, all of which are difficult or impossible to predict accurately. To the extent that our assumptions differ from actual results, our ability to meet such forward-looking statements, including our ability to generate positive cash flow from operations, provide dividends to stockholders and maintain the value of our real estate properties, may be significantly hindered.

Executive Summary
HTA is one of the largest publicly-traded REITsREIT 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 property management and leasing platform to generate strong tenant 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 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 $4.3$7.0 billion to create a portfolio of MOBs and other healthcare assets consisting of approximately 17.824.2 million square feet of GLA throughout the U.S. As of March 31,September 30, 2017, our portfolio included $2.24 billion of investments, net of development credits received at closing in connection with our Duke Acquisition, which includes a 50% ownership interest in an unconsolidated joint venture for $68.8 million as of the date of acquisition. Our only remaining obligations related to the Duke Acquisition are the potential acquisition of a land parcel in Miami, FL and a single property in Texas that are each currently excluded from our purchase obligations due to current outstanding physical condition issues.
As of September 30, 2017, approximately 96% of our portfolio, based on GLA, was located on the campuses of, or aligned with, nationally or regionally recognized healthcare systems. Our portfolio is diversified geographically across 3133 states, with no state having more than 13%19% of our total GLA as of March 31,September 30, 2017. We are concentrated in 1520 to 2025 key markets that are experiencing higher economic and demographic trends than other markets, on average, that we expect will drive demand for MOBs. Approximately 92% of our portfolio, based on GLA, is located in the top 75 MSAs with Atlanta, Boston, Hartford/New Haven, Dallas, Houston Phoenix and Orange County/Los AngelesTampa being our largest markets by investment.

Non-GAAP Financial Measures
FFO and Normalized FFO
We compute FFO in accordance with the current standards established by the National Association of Real Estate Investment Trusts (“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 partnership unitsOP Units included in diluted shares (only applicable to HTA)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 partnership unitsOP Units included in diluted shares (only applicable to HTA)the Company) and the weighted average shares of HTAour common stock or HTALP partnership unitsOP 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; (v)(vi) gain or loss on sales of real estate; (vi)(vii) gain or loss on extinguishment of debt; (viii) income or loss from unconsolidated joint venture; and (vii)(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;adjustments and (ii) amortization of below and above market leases/leasehold interests.interests and lease termination fees. 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.
To facilitate the comparison of Cash NOI between periods, we calculate comparable amounts for a subset of our owned 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, 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 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 March 31,September 30, 2017, we had liquidity of $690.5$928.9 million, including $674.5$919.5 million available under our unsecured revolving credit facility (includes(which includes the impact of $5.5 million of outstanding letters of credit) and $16.0$9.4 million of cash and cash equivalents.
As of March 31, 2017, $177.1 million was available for issuance under our $300.0 million ATM program. In addition, we had unencumbered propertiesassets with a gross book value of $3.2$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 March 31,September 30, 2017, we estimate that our expenditures for capital improvements for the remainder of 2017 will range from $20.0$10.0 million to $25.0$15.0 million depending on leasing activity. As of March 31,September 30, 2017, we had $3.8$2.9 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

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. 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 threenine months ended March 31,September 30, 2017, net cash used in investing activities primarily related to the investment in real estate of $34.7was $2.4 billion, investment in unconsolidated joint venture was $68.8 million, and capital expenditures of $12.9was $43.0 million, partially offset by restricted cash, escrow deposits and other assets of $5.8 million and proceeds from the sale of real estate of $4.7 million. For the threenine months ended March 31,September 30, 2016, net cash used in investing activities primarily related to the investment in real estate of $158.7was $532.5 million and capital expenditures was $34.1 million, partially offset by proceeds from the sale of $8.8real estate of $23.4 million. We anticipate cash flows used in investing activities to increase as we continue to acquire more properties.

Dividends
The amount of dividends HTA payswe pay to itsour stockholders is determined by itsour Board of Directors, in itstheir 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. HTA hasWe 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. HTA’sOur organizational documents do not establish a limit on dividends that may constitute a return of capital for federal income tax purposes. The dividend HTA payswe pay to itsour stockholders is equal to the distributions received from HTALP in accordance with the terms of HTALP’s partnership agreement. It is HTA’sour intention to continue to pay dividends. However, HTA’sour Board of Directors may reduce our dividend rate and HTAwe cannot guarantee the timing and amount of dividends that it may pay in the future, if any.

Off-Balance Sheet Arrangements
As of and during the three months ended March 31,September 30, 2017,, we hadhave no material off-balance sheet arrangements.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.
