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) acquisition-related 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 extinguishment of debt; and (vii) other income or expense. HTA believes that NOI provides an accurate measure of the operating performance of its operating assets because NOI excludes certain items that are not associated with the management of the properties. Additionally, HTA believes that NOI is a widely accepted measure of comparative operating performance of real estate investment trusts (“REITs”). However, HTA’s 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, net; (ii) amortization of below and above market leases/leasehold interests, net; and (iii) lease termination fees. HTA believes that Cash NOI provides another measurement of the operating performance of its operating assets. Additionally, HTA believes that Cash NOI is a widely accepted measure of comparative operating performance of REITs. However, HTA’s 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, HTA calculates comparable amounts for a subset of its owned properties referred to as “Same-Property.” Same-Property Cash NOI excludes properties which have not been owned and operated by HTA during the entire span of all periods presented or are intended to be sold 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.

HTA computes 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 (computed in accordance with GAAP), excluding gains or losses from the sales of real estate property and impairment write-downs of depreciable assets, plus real estate depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures. HTA presents this non-GAAP financial measure because it considers it an important supplemental measure of its operating performance and believes 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 asset values have historically risen or fallen based on market conditions, many industry investors have considered 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.

HTA’s methodology for calculating FFO may be different from methods utilized by other REITs and, accordingly, may not be comparable to such other REITs. FFO should not be considered as an alternative to net income or loss attributable to common stockholders (computed in accordance with GAAP) as an indicator of our financial performance, nor is it indicative of cash available to fund cash needs. FFO should be reviewed in connection with other GAAP measurements.

HTA computes Normalized FFO, which excludes from FFO: (i) acquisition-related expenses; (ii) net 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 units included in diluted shares; and (v) other normalizing items. HTA presents 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. HTA’s 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 (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.

HTA also computes Normalized FAD, which excludes from Normalized FFO: (i) other income or expense; (ii) non-cash compensation expense; (iii) straight-line rent adjustments, net; (iv) amortization of below and above market leases/leasehold interests, net; (v) deferred revenue - tenant improvement related; (vi) amortization of deferred financing costs and debt premium/discount; and (vii) recurring capital expenditures, tenant improvements and leasing commissions. HTA believes this non-GAAP financial measure provides a meaningful supplemental measure of our operating performance. Normalized FAD should not be considered as an alternative to net income or loss attributable to common stockholders (computed in accordance with GAAP) as an indicator of our financial performance, nor is it indicative of cash available to fund all of cash needs. Normalized FAD should be reviewed in connection with other GAAP measurements.

2Q 2015 I Supplemental Information Healthcare Trust of America, Inc. I 19 Reporting Definitions Adjusted Earnings Before Interest, Taxes, Depreciation and Amortization (Adjusted EBITDA): Is presented on an assumed annualized basis. We define Adjusted EBITDA for HTA as net income computed in accordance with GAAP plus depreciation and amortization, interest expense and net change in the fair value of derivative financial instruments, gain on sales of real estate, acquisition-related expenses, impairment, non-cash compensation expense, pro forma impact of our acquisitions and gain on extinguishment of debt. We consider Adjusted EBITDA an important measure because it provides additional information to allow management, investors, and our current and potential creditors to evaluate and compare our core operating results and our ability to service debt. Annualized Base Rent: Annualized base rent is calculated by multiplying contractual base rent for June 2015 by 12 (excluding the impact of abatements, concessions, and straight- line rent).  Cash Net Operating Income (Cash NOI):  Cash NOI is a non-GAAP financial measure which excludes from NOI: (i) straight-line rent adjustments, net; (ii) amortization of below and above market leases/leasehold interests, net; and (iii) lease termination fees. HTA believes that Cash NOI provides another measurement of the operating performance of its operating assets. Additionally, HTA believes that Cash NOI is a widely accepted measure of comparative operating performance of real estate investment trusts (REITs). However, HTA’s 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. Credit Ratings: Credit ratings of our tenants or their parent companies. Funds from Operations (FFO): HTA computes 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 (computed in accordance with GAAP), excluding gains or losses from sales of real estate property and impairment write-downs of depreciable assets, plus real estate depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures. HTA presents this non-GAAP financial measure because it considers it an important supplemental measure of its operating performance and believes 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 asset values have historically risen or fallen based on market conditions, many industry investors have considered 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. HTA’s methodology for calculating FFO may be different from methods utilized by other REITs and, accordingly, may not be comparable to such other REITs. FFO should not be considered as an alternative to net income or loss attributable to common stockholders (computed in accordance with GAAP) as an indicator of our financial performance, nor is it indicative of cash available to fund cash needs. FFO should be reviewed in connection with other GAAP measurements. Gross Leasable Area (GLA): Gross leasable area (in square feet). Gross Real Estate Investments: Based on acquisition price. Leased Rate: Leased rate represents the percentage of total gross leasable area that is leased, including month-to-month leases and leases which have been executed, but which have not yet commenced, as of the date reported. Metropolitan Statistical Area (MSA): Is a geographical region with a relatively high population density at its core and close economic ties throughout the area. MSAs are defined by the Office of Management and Budget. Net Operating Income (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) acquisition-related 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 extinguishment of debt; and (vii) other income or expense. HTA believes that NOI provides an accurate measure of the operating performance of its operating assets because NOI excludes certain items that are not associated with management of the properties. Additionally, HTA believes that NOI is a widely accepted measure of comparative operating performance in the evaluation of REITs. However, HTA’s 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. Normalized Funds Available for Distribution (Normalized FAD): HTA computes Normalized FAD, which excludes from Normalized FFO: (i) other income or expense; (ii) non-cash compensation expense; (iii) straight-line rent adjustments, net; (iv) amortization of below and above market leases/leasehold interests, net; (v) deferred revenue - tenant improvement related; (vi) amortization of deferred financing costs and debt premium/discount; and (vii) recurring capital expenditures, tenant improvements and leasing commissions. HTA believes this non-GAAP financial measure provides a meaningful supplemental measure of our operating performance. Normalized FAD should not be considered as an alternative to net income or loss attributable to common stockholders (computed in accordance with GAAP) as an indicator of our financial performance, nor is it indicative of cash available to fund cash needs. Normalized FAD should be reviewed in connection with other GAAP measurements. Normalized Funds From Operations (Normalized FFO): HTA computes Normalized FFO, which excludes from FFO: (i) acquisition-related expenses; (ii) net 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 units included in diluted shares; and (v) other normalizing items. HTA presents 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. HTA’s methodology for calculating Normalized FFO may be different from the methods utilized by other REITs and, accordingly, may not be comparable to such other REITs. Normalized FFO should not be considered as an alternative to net income or loss attributable to common stockholders (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. Off-Campus:  A building or portfolio that is not located on or adjacent to key hospital based-campuses or is not aligned with recognized healthcare systems. On-Campus/Aligned:  On-campus refers to a property that is located on or adjacent to a healthcare system.
