(1) Non-GAAP financial measures, including FFO, Core FFO and NOI, are reconciled to their most directly comparable GAAP measure and defined (together with other words and phrases used herein) in the Schedules to this press release and in the supplemental financial information. 
First quarter 2017 net income increased $2.4 million, driven primarily by incremental NOI generated from 95 self storage properties acquired between April 1, 2016 and March 31, 2017 and same store NOI growth, partially offset by increases in depreciation and amortization, interest expense and general and administrative expenses.
First quarter 2017 basic earnings per share decreased $0.09 per share and diluted earnings per share decreased $0.06 per share. In addition to the items affecting net income described above, the comparison of earnings per share amounts between periods is affected by the allocation of net income to noncontrolling interests pursuant to GAAP. Additional information on NSA's allocation of net income (loss) can be found in the Glossary to the supplemental financial information under "Hypothetical Liquidation at Book Value Method."
First quarter 2017 FFO per share increased 26.1% and Core FFO per share increased 16.0%. The increases in FFO and Core FFO were primarily the result of $10.6 million of incremental NOI from 95 self storage properties acquired between April 1, 2016 and March 31, 2017, same store NOI growth of $2.4 million, $1.8 million of management fees and other revenue and $1.1 million of the Company's share of FFO and Core FFO from its unconsolidated real estate venture, partially offset by increases of $2.8 million of general and administrative expenses, $2.5 million of interest expense and $1.8 million of distributions to subordinated performance unitholders.

Credit Facility
During February 2017, NSA entered into agreements with a syndicated group of lenders to partially exercise its expansion option under its credit facility, increasing total capacity by $170 million for a total credit facility of $895 million. This expansion increased the total borrowing capacity under NSA's five and six-year term loan tranches by $10 million and $55 million, respectively, and created a new $105 million seven-year term loan tranche.

Dividends
On February 23, 2017, NSA's Board of Trustees declared a quarterly cash dividend of $0.24 per common share, which was paid on March 30, 2017 to holders of record as of March 15, 2017.
Supplemental Financial Information
The full text of this earnings release and supplemental financial information, including certain financial information referenced in this release, are available on NSA's website at http://ir.nationalstorageaffiliates.com/quarterly-reporting and as exhibit 99.1 to the Company's Form 8-K furnished to the SEC on May 3, 2017.
Non-GAAP Financial Measures & Glossary
This press release contains certain non-GAAP financial measures. These non-GAAP measures are presented because NSA's management believes these measures help investors understand NSA's business, performance and ability to earn and distribute cash to its shareholders by providing perspectives not immediately apparent from net income (loss). These measures are also frequently used by securities analysts, investors and other interested parties. The presentation of FFO, Core FFO and NOI in this press release are not intended to be considered in isolation or as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP. In addition, NSA's method of calculating these measures may be different from methods used by other companies, and, accordingly, may not be comparable to similar measures as calculated by other companies that do not use the same methodology as NSA. These measures, and other words and phrases used herein, are defined in the Glossary in the supplemental financial information and, where appropriate, reconciliations of these measures and other non-GAAP financial measures to their most directly comparable GAAP measures are included in the Schedules to this press release and in the supplemental financial information.

(1) Amounts represent distributions declared for subordinated performance unitholders and DownREIT subordinated performance unitholders for the periods presented.
(2) NSA combines OP units and DownREIT OP units with common shares because, after the applicable lock-out periods, OP units in the Company's operating partnership are redeemable for cash or, at NSA's option, exchangeable for common shares on a one-for-one basis and DownREIT OP units are also redeemable for cash or, at NSA's option, exchangeable for OP units in our operating partnership on a one-for-one basis, subject to certain adjustments in each case. Subordinated performance units, DownREIT subordinated performance units, and LTIP units may also, under certain circumstances, be convertible into or exchangeable for common shares (or other units that are convertible into or exchangeable for common shares). See footnote(3) for additional discussion of subordinated performance units, DownREIT subordinated performance units, and LTIP units in the calculation of FFO and Core FFO per share and unit.

(3) Adjustment accounts for the difference between the weighted average number of shares used to calculate diluted earnings per share and the weighted average number of shares used to calculate FFO and Core FFO per share and unit. Diluted earnings per share is calculated using the two-class method for the company's restricted common shares, the treasury stock method for certain unvested LTIP units, and includes the assumption of a hypothetical conversion of subordinated performance units, DownREIT subordinated performance units and LTIP units into OP units, even though such units may only be convertible into OP units (i) after a lock-out period and (ii) upon certain events or conditions. For additional information about the conversion of subordinated performance units and DownREIT subordinated performance units into OP units, see Note 10 to the Company's most recent Annual Report on Form 10-K, filed with the Securities and Exchange Commission. The computation of weighted average shares and units for FFO and Core FFO per share and unit includes all restricted common shares and LTIP units that participate in distributions and excludes all subordinated performance units and DownREIT subordinated performance units because their effect has been accounted for through the allocation of FFO to the related unitholders based on distributions declared.
(4) Represents the effect of adjusting the numerator to consolidated net income (loss) prior to GAAP allocations for noncontrolling interests and the application of the two-class method and treasury stock method, as described in footnote (3).

(2) Balances exclude 260,400 long-term incentive plan ("LTIP") units which only vest and participate in dividend distributions upon the future contribution of properties from the PROs.
(3) If converted balance assumes that each subordinated performance unit (including each DownREIT subordinated performance unit) is convertible into OP units, notwithstanding the two-year lock-out period on conversions, and that each subordinated performance unit would on average convert on a hypothetical basis into an estimated 1.41 OP units based on historical financial information for the trailing twelve months ended March 31, 2017. The hypothetical conversions are calculated by dividing the average cash available for distribution, or CAD, per subordinated performance unit by 110% of the CAD per OP unit over the same period. The Company anticipates that as CAD grows over time, the conversion ratio will also grow, including to levels that may exceed these amounts.

Glossary
 
 
 
 
 
This Earnings Release and Supplemental Information include certain financial and operating measures used by NSA management that are not calculated in accordance with accounting principles generally accepted in the United States, or GAAP. NSA's definitions and calculations of these non-GAAP financial and operating measures and other terms may differ from the definitions and methodologies used by other real estate companies and, accordingly, may not be comparable. These non-GAAP financial and operating measures should not be considered an alternative to GAAP net income or any other GAAP measurement of performance and should not be considered an alternative measure of liquidity.
 
 
 
 
 
AVERAGE ANNUALIZED RENTAL REVENUE PER OCCUPIED SQUARE FOOT: Average annualized rental revenue per occupied square foot is computed by dividing annualized rental revenue per our statements of operations (which includes fees and is net of any discounts) by average occupied square feet.
AVERAGE OCCUPANCY: Average occupancy is calculated based on the average of the month-end occupancy immediately preceding the period presented and the month-end occupancies included in the respective period presented.
CAPITAL EXPENDITURES DEFINITIONS
ACQUISITIONS CAPITAL EXPENDITURES: Acquisitions capital expenditures represents the portion of capital expenditures capitalized during the current period that were identified and underwritten prior to a property's acquisition.
RECURRING CAPITAL EXPENDITURES: Recurring capital expenditures represents the portion of capital expenditures that are deemed to replace the consumed portion of acquired capital assets and extend their useful lives.
REVENUE ENHANCING CAPITAL EXPENDITURES: Revenue enhancing capital expenditures represents the portion of capital expenditures that are made to enhance the revenue and value of an asset from its original purchase condition.
EBITDA: We define EBITDA as net income (loss), as determined under GAAP, plus interest expense, loss on early extinguishment of debt, income taxes, depreciation and amortization expense and the Company's share of unconsolidated real estate venture depreciation and amortization. We define ADJUSTED EBITDA as EBITDA plus acquisition costs, the Company's share of unconsolidated real estate venture acquisition costs, organizational and offering expenses, equity-based compensation expense, losses on sale of properties, and impairment of long-lived assets; and by subtracting gains on sale of properties and debt forgiveness. These further adjustments eliminate the impact of items that we do not consider indicative of our core operating performance. In evaluating EBITDA and Adjusted EBITDA, you should be aware that in the future we may incur expenses that are the same as or similar to some of the adjustments in this presentation. Our presentation of EBITDA and Adjusted EBITDA should not be construed as an inference that our future results will be unaffected by unusual or non-recurring items.
We present EBITDA and Adjusted EBITDA because we believe they assist investors and analysts in comparing our performance across reporting periods on a consistent basis by excluding items that we do not believe are indicative of our core operating performance. EBITDA and Adjusted EBITDA have limitations as an analytical tool. Some of these limitations are:
EBITDA and Adjusted EBITDA do not reflect our cash expenditures, or future requirements, for capital expenditures, contractual commitments or working capital needs;
EBITDA and Adjusted EBITDA do not reflect the significant interest expense, or the cash requirements necessary to service interest or principal payments, on our debts;
although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and EBITDA and Adjusted EBITDA do not reflect any cash requirements for such replacements;

20

nsalogoa02a11.jpg

Adjusted EBITDA excludes equity-based compensation expense, which is and will remain a key element of our overall long-term incentive compensation package, although we exclude it as an expense when evaluating our ongoing operating performance for a particular period;
EBITDA and Adjusted EBITDA do not reflect the impact of certain cash charges resulting from matters we consider not to be indicative of our ongoing operations; and
other companies in our industry may calculate EBITDA and Adjusted EBITDA differently than we do, limiting its usefulness as a comparative measure.
We compensate for these limitations by considering the economic effect of the excluded expense items independently as well as in connection with our analysis of net income (loss). EBITDA and Adjusted EBITDA should be considered in addition to, but not as a substitute for, other measures of financial performance reported in accordance with GAAP, such as total revenues, income from operations, and net income (loss).
FUNDS FROM OPERATIONS: Funds from operations, or FFO, is a widely used performance measure for real estate companies and is provided here as a supplemental measure of our operating performance. The April 2002 National Policy Bulletin of NAREIT, which we refer to as the White Paper, as amended, defines FFO as net income (as determined under GAAP), excluding gains (or losses) from sales of real estate and related impairment charges, plus real estate depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures. We include amortization of customer in-place leases in real estate depreciation and amortization in the calculation of FFO because we believe the amortization of customer in-place leases is analogous to real estate depreciation, as the value of such intangibles is inextricably connected to the real estate acquired. Distributions declared on subordinated performance units and DownREIT subordinated performance units represent our allocation of FFO to noncontrolling interests held by subordinated performance unitholders and DownREIT subordinated performance unitholders for the purpose of calculating FFO attributable to common shareholders, OP unitholders, and LTIP unitholders. We define CORE FFO as FFO, as further adjusted to eliminate the impact of certain items that we do not consider indicative of our core operating performance. These further adjustments consist of acquisition costs, organizational and offering costs, gains on debt forgiveness, gains (losses) on early extinguishment of debt, and after adjustments for unconsolidated partnerships and joint ventures.
Management uses FFO and Core FFO as key performance indicators in evaluating the operations of our properties. Given the nature of our business as a real estate owner and operator, we consider FFO and Core FFO as key supplemental measures of our operating performance that are not specifically defined by GAAP. We believe that FFO and Core FFO are useful to management and investors as a starting point in measuring our operational performance because FFO and Core FFO exclude various items included in net income (loss) that do not relate to or are not indicative of our operating performance such as gains (or losses) from sales of self storage properties and depreciation, which can make periodic and peer analyses of operating performance more difficult. Our computation of FFO and Core FFO may not be comparable to FFO reported by other REITs or real estate companies.
FFO and Core FFO should be considered in addition to, but not as a substitute for, other measures of financial performance reported in accordance with GAAP, such as total revenues, operating income and net income (loss). FFO and Core FFO do not represent cash generated from operating activities determined in accordance with GAAP and are not a measure of liquidity or an indicator of our ability to make cash distributions. We believe that to further understand our performance, FFO and Core FFO should be compared with our reported net income (loss) and considered in addition to cash flows computed in accordance with GAAP, as presented in our consolidated financial statements.
HYPOTHETICAL LIQUIDATION AT BOOK VALUE METHOD: In accordance with GAAP, the Company allocates income (loss) utilizing the hypothetical liquidation at book value ("HLBV") method, in which the Company allocates income or loss based on the change in each unitholders’ claim on the net assets of the Company's operating partnership at period end after adjusting for any distributions or contributions made during such period. The Company uses this method because of the difference between the distribution rights and priorities set forth in the operating partnership's Agreement of Limited Partnership and what is reflected by the underlying percentage ownership interests of the unitholders.
The HLBV method is a balance sheet-focused approach to income (loss) allocation. A calculation is prepared at each balance sheet date to determine the amount that unitholders would receive if the operating partnership

21

nsalogoa02a11.jpg

were to liquidate all of its assets (at GAAP net book value) and distribute the resulting proceeds to its creditors and unitholders based on the contractually defined liquidation priorities. The difference between the calculated liquidation distribution amounts at the beginning and the end of the reporting period, after adjusting for capital contributions and distributions, is used to derive each unitholder's share of the income (loss) for the period. Due to the stated liquidation priorities and because the HLBV method incorporates non-cash items such as depreciation expense, in any given period, income or loss may be allocated disproportionately to unitholders as compared to their respective ownership percentage in the operating partnership, and net income (loss) attributable to National Storage Affiliates Trust could be more or less net income than actual cash distributions received and more or less income or loss than what may be received in the event of an actual liquidation. Additionally, the HLBV method could result in net income (or net loss) attributable to National Storage Affiliates Trust during a period when the Company reports consolidated net loss (or net income), or net income (or net loss) attributable to National Storage Affiliates Trust in excess of the Company's consolidated net income (or net loss). The computations of basic and diluted earnings (loss) per share may be materially affected by these disproportionate income (loss) allocations, resulting in volatile fluctuations of basic and diluted earnings (loss) per share. Readers and investors are cautioned not to place undue reliance on NSA's income (loss) allocations or earnings (loss) per share without considering the effects described above, including the effect that depreciation and amortization have on income (loss), net book value and the application of the HLBV method.
LONG-TERM INCENTIVE PLAN UNITS: Long-term incentive plan units, or LTIP units, are a special class of partnership interest in our operating partnership that allow the holder to participate in the ordinary and liquidating distributions received by holders of the operating partnership units (subject to the achievement of specified levels of profitability by our operating partnership or the achievement of certain events). Upon vesting, and after achieving parity with operating partnership units, vested LTIP units may be converted into an equal number of operating partnership units, and thereafter have all the rights of operating partnership units, including redemption rights.
NET DEBT TO ANNUALIZED CURRENT QUARTER ADJUSTED EBITDA: We calculate net debt to Adjusted EBITDA as total debt (inclusive of $10.5 million of fair value of debt adjustments and $6.2 million of debt issuance costs) less cash and cash equivalents, divided by annualized current quarter Adjusted EBITDA.
NET OPERATING INCOME:  We define net operating income, or NOI, as net income (loss), as determined under GAAP, plus general and administrative expenses, depreciation and amortization, interest expense, loss on early extinguishment of debt, equity in earnings (losses) of unconsolidated real estate ventures, acquisition costs, organizational and offering expenses, income tax expense, impairment of long-lived assets, losses on the sale of properties and non-operating expense and by subtracting management fees and other revenue, gains on sale of properties, debt forgiveness, and non-operating income. NOI is not a measure of performance calculated in accordance with GAAP.
We believe NOI is useful to investors in evaluating our operating performance because:
NOI is one of the primary measures used by our management and our PROs to evaluate the economic productivity of our properties, including our ability to lease our properties, increase pricing and occupancy and control our property operating expenses;
NOI is widely used in the real estate industry and the self storage industry to measure the performance and value of real estate assets without regard to various items included in net income that do not relate to or are not indicative of operating performance, such as depreciation and amortization, which can vary depending upon accounting methods, the book value of assets, and the impact of our capital structure; and
We believe NOI helps our investors to meaningfully compare the results of our operating performance from period to period by removing the impact of our capital structure (primarily interest expense on our outstanding indebtedness) and depreciation of the cost basis of our assets from our operating results.
There are material limitations to using a non-GAAP measure such as NOI, including the difficulty associated with comparing results among more than one company and the inability to analyze certain significant items, including depreciation and interest expense, that directly affect our net income (loss). We compensate for these limitations by considering the economic effect of the excluded expense items independently as well as in connection with our analysis of net income (loss). NOI should be considered in addition to, but not as a substitute

22

nsalogoa02a11.jpg

for, other measures of financial performance reported in accordance with GAAP, such as total revenues, income from operations and net loss.
NET OPERATING INCOME MARGIN: The ratio of NOI divided by total rental and other property-related revenue.
NON-SAME STORE PORTFOLIO: Non-same store portfolio comprises those properties that do not meet the Same Store portfolio property definition. 
OCCUPANCY AT PERIOD END:  Represents total occupied rentable square feet divided by total rentable square feet at period end.
OPERATING PARTNERSHIP UNITS:  Operating partnership units, or OP Units, are Class A common units of limited partner interest in our operating partnership which are economically equivalent to our common shares. We also own certain of our self storage properties through other consolidated limited partnership subsidiaries of our operating partnership, which we refer to as "DownREIT partnerships." The DownREIT partnerships issue certain units of limited partner or limited liability company interest that are intended to be economically equivalent to our OP units, which we define as DOWNREIT OPERATING PARTNERSHIP UNIT EQUIVALENTS, or DownREIT OP units.
PROs: Participating regional operators, or "PROs", are our experienced regional self storage operators with local operational focus and expertise. As of March 31, 2017, our Company had eight PROs, SecurCare Self Storage, Northwest Self Storage, Optivest Properties, Guardian Storage Centers, Move It Self Storage, Storage Solutions, Hide-Away and Personal Mini.
RENTABLE SQUARE FEET: Rentable square feet includes all enclosed self storage units but excludes commercial, residential, and covered parking space.
RESTRICTED COMMON SHARES: Restricted common shares are common shares that are subject to restrictions on transferability subject to vesting and such other restrictions. Generally, a participant granted restricted common shares has all of the rights of a shareholder, including, without limitation, the right to vote and the right to receive dividends on the restricted common shares. Holders of restricted common shares are prohibited from selling such shares until they vest.
SAME STORE PORTFOLIO: Our same store portfolio is defined as those properties owned and operated for the entirety of the applicable periods presented, excluding any properties sold or expected to be sold or where we completed a storage space expansion which caused the property's year-over-year operating results to no longer be comparable. Our 2017 same store portfolio consists of only those properties that were included in the Company's consolidated results since January 1, 2016, excluding two properties we plan to dispose of during 2017.
SUBORDINATED PERFORMANCE UNITS:  Subordinated performance units, or SP Units, are Class B common units of limited partner interest in our operating partnership. SP units, which are linked to the performance of specific contributed portfolios, are intended to incentivize our PROs to drive operating performance and support the sustainability of the operating cash flow generated by the contributed self storage properties that they continue to manage on our behalf. Because subordinated performance unit holders receive distributions only after portfolio-specific minimum performance thresholds are satisfied, we believe SP units play a key role in aligning the interests of our PROs with us and our shareholders. The DownREIT partnerships also issue units of limited partner interest that are intended to be economically equivalent to our SP units, which we define as DOWNREIT SUBORDINATED PERFORMANCE UNIT EQUIVALENTS, or DownREIT SP units.
