Included in this press release are Cash Available for Distribution, or CAD, net operating income, or NOI, same store net operating income, or same store NOI, Adjusted Earnings before Interest, Taxes, Depreciation and Amortization, or Adjusted EBITDA and EPRA net asset value, or EPRA NAV, each a "non-GAAP financial measure," which measures NRE's historical or future financial performance that is different from measures calculated and presented in accordance with accounting principles generally accepted in the United States, or U.S. GAAP, within the meaning of the applicable Securities and Exchange Commission, or SEC, rules. NRE believes these metrics can be a useful measure of its performance which is further defined below.

We believe that CAD provides investors and management with a meaningful indicator of operating performance. We also believe that CAD is useful because it adjusts for a variety of items that are consistent with presenting a measure of operating performance (such as transaction costs, depreciation and amortization, equity-based compensation, realized gain on sales, net, asset impairment and non-recurring bad debt expense). We adjust for transaction costs because these costs are not a meaningful indicator of our operating performance. For instance, these transaction costs include costs such as professional fees associated with new investments, which are expenses related to specific transactions. Management also believes that quarterly distributions are principally based on operating performance and our board of directors includes CAD as one of several metrics it reviews to determine quarterly distributions to stockholders. The definition of CAD may be adjusted from time to time for our reporting purposes in our discretion, acting through our audit committee or otherwise. CAD may fluctuate from period to period based upon a variety of factors, including, but not limited to, the timing and amount of investments, new leases, repayments and asset sales, capital raised, use of leverage, changes in the expected yield of investments and the overall conditions in commercial real estate and the economy generally.

We calculate CAD by subtracting from or adding to net income (loss) attributable to common stockholders, noncontrolling interests and the following items: depreciation and amortization items including straight-line rental income or expense (excluding amortization of rent free periods), amortization of above/below market leases, amortization of deferred financing costs, amortization of discount on financings and other and equity-based compensation; other gain (loss), net (excluding any realized gain (loss) on the settlement on foreign currency derivatives); realized gain on sales, net; impairment on depreciable property; acquisition gains or losses; transaction costs; foreign currency gains (losses) related to sales; impairment on goodwill and other intangible assets; the incentive fee relating to the Amended and Restated Management Agreement and one-time events pursuant to changes in U.S. GAAP and certain other non-recurring items. These items, if applicable, include any adjustments for unconsolidated ventures.

CAD should not be considered as an alternative to net income (loss) attributable to common stockholders, determined in accordance with U.S. GAAP, as an indicator of operating performance. In addition, our methodology for calculating CAD involves subjective judgment and discretion and may differ from the methodologies used by other comparable companies, including other REITs, when calculating the same or similar supplemental financial measures and may not be comparable with these companies.

We believe NOI is a useful metric for evaluating the operating performance of our real estate portfolio in the aggregate. Portfolio results and performance metrics represent 100% for all consolidated investments. Net operating income represents total property and related revenues, adjusted for: (i) amortization of above/below market leases; (ii) straight-line rent (except with respect to results and performance metrics represent 100% for all consolidated investments. Net operating income reflects total property and related revenues, adjusted for: (i) amortization of above/below market leases; (ii) straight-line rent (except with respect to rent free period); (iii) other items such as adjustments related to joint ventures and non-recurring bad debt expense and less property operating expenses. However, the usefulness of NOI is limited because it excludes general and administrative costs, interest expense, transaction costs, depreciation and amortization expense, realized gain on sales, net and other and other items under U.S. GAAP and capital expenditures and leasing costs, all of which may be significant economic costs. NOI may fail to capture significant trends in these components of U.S. GAAP net income (loss) which further limits its usefulness.

NOI should not be considered as an alternative to net income (loss), determined in accordance with U.S. GAAP, as an indicator of operating performance. In addition, our methodology for calculating NOI involves subjective judgment and discretion and may differ from the methodologies used by other comparable companies, including other REITs, when calculating the same or similar supplemental financial measures and may not be comparable with these companies.

We believe same store NOI is a useful metric for evaluating the operating performance as it reflects the operating performance of the real estate portfolio and provides a better measure of operational performance for a quarter-over-quarter comparison. Same store net operating income is presented for the same store portfolio, which comprises all properties that were owned by us at the end of the reporting period. We define same store net operating income as NOI excluding (i) properties that were acquired or sold during the period, (ii) impact of foreign currency changes and (iii) amortization of above/below market leases. We consider same store NOI to be an appropriate and useful supplemental performance measure. Same store NOI should not be considered as an alternative to net income (loss), determined in accordance with U.S. GAAP, as an indicator of operating performance. In addition, our methodology for calculating same store net operating income involves subjective judgment and discretion and may differ from the methodologies used by other comparable companies, including other REITs, when calculating the same or similar supplemental financial measures and may not be comparable with these companies. Same store portfolio is defined as properties in operation throughout the full periods presented under the comparison, excluding the impact of foreign currency changes, and included 23 properties and our preferred equity segment (in case of quarter over quarter and year over year comparison).

We believe that Adjusted EBITDA provides investors and management with a meaningful indication of operating performance. We also believe that Adjusted EBITDA is useful because it adjusts for a variety of items that are consistent with presenting a measure of operating performance (such as depreciation and amortization items, interest expense, income tax benefit (expense), realized gain on sales, net, transaction costs, equity-based compensation and asset impairment). The definition of Adjusted EBITDA may be adjusted from time to time for our reporting purposes in our discretion, acting through our audit committee or otherwise. Adjusted EBITDA may fluctuate from period to period based upon a variety of factors, including, but not limited to, the timing and amount of investments, repayments and asset sales, capital raised, changes in the expected yield of investments and the overall conditions in commercial real estate and the economy generally.

We calculate Adjusted EBITDA by subtracting from or adding to net income (loss) attributable to common stockholders, non-controlling interests and the following items: depreciation and amortization items including straight-line rental income or expense (excluding amortization of rent free periods), amortization of above/below market leases and equity-based compensation; interest expense; income tax (benefit) expense; other gain (loss), net (excluding any realized gain (loss) on the settlement on foreign currency derivatives); realized gain on sales, net; impairment on depreciable property; acquisition gains or losses; transaction costs; foreign currency gains (losses) related to sales; impairment on goodwill and any other intangible assets; the incentive fee relating to the Amended and Restated Management Agreement and one-time events pursuant to changes in U.S. GAAP and certain other non-recurring items. These items, if applicable, include any adjustments for unconsolidated ventures.

Adjusted EBITDA should not be considered as an alternative to net income (loss) attributable to common stockholders, determined in accordance with U.S. GAAP, as an indicator of operating performance. In addition, our methodology for calculating Adjusted EBITDA involves subjective judgment and discretion and may differ from the methodologies used by other comparable companies, including other REITs, when calculating the same or similar supplemental financial measures and may not be comparable with these companies.

As our entire portfolio is based in Europe, our management calculates European Public Real Estate Association net asset value, or EPRA NAV, a non-GAAP measure, to compare our balance sheet to other European real estate companies and believes that disclosing EPRA NAV provides investors with a meaningful measure of our net asset value. Our calculation of EPRA NAV is derived from our U.S. GAAP balance sheet with adjustments reflecting our interpretation of EPRA's best practices recommendations. Accordingly, our calculation of EPRA NAV may be different from how other European real estate companies calculate EPRA NAV, which utilize International Financial Reporting Standards ("IFRS") to prepare their balance sheet. EPRA NAV makes adjustments to net assets as determined in accordance with U.S. GAAP in order to provide our stockholders a measure of fair value of our assets and liabilities with a long-term investment strategy. This performance measure excludes assets and liabilities that are not expected to materialize in normal circumstances. EPRA NAV includes the revaluation of investment properties and excludes the fair value of financial instruments that we intend to hold to maturity, deferred tax and goodwill that resulted from deferred tax. All other assets, including real property and investments reported at cost are adjusted to fair value based upon an independent third party valuation conducted in December and June of each year. This measure should not be considered as an alternative to measuring our net assets in accordance with U.S. GAAP.

As an opinion, the valuation by Cushman & Wakefield LLP referenced in this release is not a measure of realizable value and may not reflect the amount that would be received if the property in question were sold. Real estate valuation is inherently subjective due to, among other factors, the individual nature of each property, its location, the expected future rental revenues from that particular property and the valuation methodology adopted. Real estate valuations are subject to a large degree of uncertainty and are made on the basis of assumptions and methodologies that may not prove to be accurate, particularly in periods of volatility, low transaction flow or restricted debt availability in the commercial or residential real estate markets. For example, in the appraisal, a number of the properties were valued using the special assumption that such properties would be purchased through a tax-efficient special purpose vehicle, and is therefore subject to lower purchaser transaction expenses. If one or more assumptions are incorrect, the value may be materially lower than the appraised value.
