Forward-Looking Statements
We make forward-looking statements in this report that are subject to risks and
uncertainties. These forward-looking statements include information about
possible or assumed future results of our business, financial condition,
liquidity, results of operations, plans and objectives. When we use the words
"believe," "expect," "anticipate," "estimate," "plan," "continue," "intend,"
"should," "may," or similar expressions, we intend to identify forward-looking
statements.
The forward-looking statements contained in this report reflect our current
views about future events and are subject to numerous known and unknown risks,
uncertainties, assumptions, and changes in circumstances that may cause our
actual results to differ significantly from those expressed in any
forward-looking statement. One of the most significant factors is the ongoing
and potential impact of the current outbreak of COVID-19 on the economy, the
self storage industry and the broader financial markets, which may have a
significant negative impact on the Company's financial condition, results of
operations and cash flows. The Company is unable to predict whether the
continuing effects of the COVID-19 pandemic will trigger a further economic
slowdown or a recession and to what extent the Company will experience
disruptions related to the COVID-19 pandemic in the second quarter or
thereafter. In particular, it is difficult to fully assess the impact of
COVID-19 at this time due to, among other factors, uncertainty regarding the
severity and duration of the outbreak domestically and internationally,
uncertainty regarding the effectiveness of federal, state and local governments'
efforts to contain the spread of COVID-19 and respond to its direct and indirect
impact on the U.S. economy and economic activity, including the timing of the
successful distribution of an effective vaccine. The current outbreak of
COVID-19 has impacted, and is likely to continue to impact, directly or
indirectly, many of the other important factors below and the risks described in
the Company's Annual Report on Form 10-K for the year ended December 31, 2020
filed with the SEC (the "Annual Report"), and the Company's subsequent filings
under the Exchange Act.

The forward-looking statements are based on our beliefs, assumptions and
expectations of our future performance, taking into account all information
currently available to us. Forward-looking statements are not predictions of
future events. These beliefs, assumptions, and expectations can change as a
result of many possible events or factors, not all of which are known to us.
Readers should carefully review our financial statements and the notes thereto,
as well as the sections entitled "Business," "Risk Factors," "Properties," and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations," described in the Company's Annual Report, and the other documents
we file from time to time with the SEC. If a change occurs, our business,
financial condition, liquidity and results of operations may vary materially
from those expressed in our forward-looking statements. Any forward-looking
statement speaks only as of the date on which it is made. New risks and
uncertainties arise over time, and it is not possible for us to predict those
events or how they may affect us. In addition, we cannot assess the impact of
each factor on our business or the extent to which any factor, or combination of
factors, may cause actual results to differ materially from those contained in
any forward-looking statements. Except as required by law, we are not obligated
to, and do not intend to, update or revise any forward-looking statements,
whether as a result of new information, future events or otherwise.
Overview
National Storage Affiliates Trust is a fully integrated, self-administered and
self-managed real estate investment trust organized in the state of Maryland on
May 16, 2013. We have elected and we believe that we have qualified to be taxed
as a REIT commencing with our taxable year ended December 31, 2015. We serve as
the sole general partner of our operating partnership, a Delaware limited
partnership formed on February 13, 2013 to conduct our business, which is
focused on the ownership, operation, and acquisition of self storage properties
located within the top 100 metropolitan statistical areas throughout the United
States.
Our executive chairman of the board of trustees and former chief executive
officer, Arlen D. Nordhagen, co-founded SecurCare Self Storage, Inc. in 1988 to
invest in and manage self storage properties. While growing SecurCare to over
150 self storage properties, Mr. Nordhagen recognized a market opportunity for a
differentiated public self storage REIT that would leverage the benefits of
national scale by integrating multiple experienced regional self storage
operators with local operational focus and expertise. We believe that his
vision, which is the foundation of the Company, aligns the interests of our
participating regional operators ("PROs"), with those of our public shareholders
by allowing our PROs to participate alongside our shareholders in our financial
performance and the performance of our PROs' managed portfolios. This structure
offers our PROs a unique opportunity to serve as regional property managers for
their managed portfolios and directly participate in the potential upside of
those

                                       26
--------------------------------------------------------------------------------

properties while simultaneously diversifying their investment to include a
broader portfolio of self storage properties.
COVID-19
We continue to closely monitor the impact of the COVID-19 pandemic on all
aspects of our business. The outbreak of COVID-19 in many countries, including
the United States, has adversely impacted economic activity. As cases of
COVID-19 have continued to increase, most states and municipalities have reacted
by instituting, extending or reinstating quarantines, mandating business and
school closures, requiring restrictions on travel, "shelter-in-place" and/or
"stay-at-home" orders, and imposing restrictions on the types of businesses that
may continue to operate. These containment measures generally do not apply to
businesses, like ours, which are designated as "essential," but may apply to
certain of our tenants, employees, vendors, lenders and joint venture partners.
As of the date of this report, our stores continue to operate and we are in
compliance with federal, state and local COVID-19 guidelines and mandates. In
response to the pandemic, we have increased the level and frequency of cleaning
and sanitation of our self storage facilities and enacted recommended social
distancing guidelines. Many of our stores feature online rental capabilities
whereby a customer can complete the entire rental process online and receive an
access code to the storage facility. For the remainder of our stores that do not
yet benefit from the online rental feature, the combination of call center and
email communication eliminates the need for any physical contact between
customers and employees.
Due to the pandemic, we experienced a slowdown in overall business activity
during the second quarter of 2020. However, we observed sustained improvement in
our property operating results during the third and fourth quarters of 2020 and
continuing into the first quarter of 2021. We continue to take proactive
measures to maintain the strength of our business and manage the impact of
COVID-19 on our operations and liquidity, including the following:
•We resumed rental rate increases for in-place tenants at the vast majority of
our stores during the third quarter of 2020;
•We are continuing to diligently manage operating expenses, including
store-level personnel costs, marketing and repairs and maintenance expenses;
•We continue to closely monitor our liquidity position. As of March 31, 2021, we
had the capacity to borrow remaining Revolver commitments of $303.8 million with
less than $5 million of debt maturing through 2022;
•On October 22, 2020, we issued $150.0 million of 2.99% senior unsecured notes
due August 5, 2030 and $100.0 million of 3.09% senior unsecured notes due
August 5, 2032 in a private placement;
•During the year ended December 31, 2020, we completed the forward offering of
4,900,000 common shares of beneficial interest under forward sale agreements at
a public offering price of $33.15 per share. On December 30, 2020, we settled a
portion of the forward offering by physically delivering 1,850,510 common shares
to the forward purchasers for net proceeds of approximately $60.0 million. On
March 22, 2021 we settled the remaining portion of the forward offering by
physically delivering 3,049,490 common shares to the forward purchasers for net
proceeds of approximately $97.3 million.
•As discussed in Note 13 in Item 1, on May 3, 2021, our operating partnership
entered into an agreement to issue $35.0 million of 2.16% senior unsecured notes
due May 4, 2026, $90.0 million of 3.00% senior unsecured notes due May 4, 2031
and $55.0 million of 3.10% senior unsecured notes due May 4, 2033 in a private
placement to certain institutional investors.
•We remain committed to acquiring properties at appropriate risk-adjusted
returns. We believe our acquisition opportunities through our captive pipeline
and relationship-based third-party deals sourced by our PROs will continue to be
a differentiating factor for us to prudently deploy capital, including through
the issuance of OP equity.
The above discussion is intended to provide shareholders with certain
information regarding the impacts of the COVID-19 pandemic on our business and
management's efforts to respond to those impacts. We are unable to predict the
impact of the COVID-19 pandemic on our business for the balance of 2021 and
thereafter. We will continue to monitor its effects and will adjust our
operations as necessary. As a result of the rapid development, fluidity and
uncertainty surrounding this situation, we expect that such information will
change, potentially

                                       27
--------------------------------------------------------------------------------

significantly, going forward and may not be indicative of the actual impact of
the COVID-19 pandemic on our financial condition, results of operations and cash
flows for the second quarter of 2021 and future periods. See "Risk Factors"
under Item 1A to the Company's Annual Report on Form 10-K for the year ended
December 31, 2020 filed with the SEC.
Our Structure
Our structure promotes operator accountability as subordinated performance units
issued to our PROs in exchange for the contribution of their properties are
entitled to distributions only after those properties satisfy minimum
performance thresholds. In the event of a material reduction in operating cash
flow, distributions on our subordinated performance units will be reduced before
or disproportionately to distributions on our common shares held by our common
shareholders. In addition, we expect our PROs will generally co-invest
subordinated equity in the form of subordinated performance units in each
acquisition that they source, and the value of these subordinated performance
units will fluctuate with the performance of their managed portfolios.
Therefore, our PROs are incentivized to select acquisitions that are expected to
exceed minimum performance thresholds, thereby increasing the value of their
subordinated equity stake. We expect that our shareholders will benefit from the
higher levels of property performance that our PROs are incentivized to deliver.
Our Property Management Platform
Through our property management platform, we direct, manage and control the
day-to-day operations and affairs of certain consolidated properties and our
unconsolidated real estate ventures. As of March 31, 2021, our property
management platform managed and controlled 288 of our consolidated properties
and 177 of our unconsolidated real estate venture properties.
We earn certain customary fees for managing and operating the properties in the
unconsolidated real estate ventures and we facilitate tenant insurance and/or
tenant warranty protection programs for tenants at these properties in exchange
for half of all proceeds from such programs.
Our PROs
The Company had ten PROs as of March 31, 2021: Northwest, Optivest, Guardian,
Move It, Storage Solutions, Hide Away, Personal Mini, Southern, Moove In and
Blue Sky. We seek to further expand our platform by continuing to recruit
additional established self storage operators, while integrating our operations
through the implementation of centralized initiatives, including management
information systems, revenue enhancement, and cost optimization programs. Our
national platform allows us to capture cost savings by eliminating redundancies
and utilizing economies of scale across the property management platforms of our
PROs while also providing greater access to lower-cost capital.
Our Consolidated Properties
We seek to own properties that are well located in high quality sub-markets with
highly accessible street access and attractive supply and demand
characteristics, providing our properties with strong and stable cash flows that
are less sensitive to the fluctuations of the general economy. Many of these
markets have multiple barriers to entry against increased supply, including
zoning restrictions against new construction and new construction costs that we
believe are higher than our properties' fair market value. We have an
attractive, high quality potential acquisition pipeline that we expect will
continue to drive our future growth.
As of March 31, 2021, we owned a geographically diversified portfolio of 667
self storage properties, located in 33 states and Puerto Rico, comprising
approximately 40.8 million rentable square feet, configured in approximately
321,000 storage units. Of these properties, 283 were acquired by us from our
PROs, 383 were acquired from third-party sellers and one was acquired from the
2016 Joint Venture.
During the three months ended March 31, 2021, we acquired 23 self storage
properties for $166.0 million, comprising approximately 1.5 million rentable
square feet, configured in approximately 11,300 storage units. Of these
acquisitions, seven were acquired from our PROs and 16 were acquired from
third-party sellers.
Our Unconsolidated Real Estate Ventures
We seek to opportunistically partner with institutional funds and other
institutional investors to acquire attractive portfolios utilizing a promoted
return structure. We believe there is significant opportunity for continued
external growth by partnering with institutional investors seeking to deploy
capital in the self storage industry. In

                                       28
--------------------------------------------------------------------------------

addition, we consider the 75% third-party interest in the Company's
unconsolidated real estate ventures, which currently own 177 properties, to
present a potential acquisition opportunity. This 75% third-party share of gross
real estate assets is approximately $1.5 billion based on the historical book
value of the joint ventures. Were we to pursue an acquisition of these
interests, it could potentially drive our future growth.
2018 Joint Venture
As of March 31, 2021, our 2018 Joint Venture, in which we have a 25% interest,
owned and operated a portfolio of 103 properties containing approximately 7.8
million rentable square feet, configured in approximately 64,000 storage units
and located across 17 states.
2016 Joint Venture
As of March 31, 2021, our 2016 Joint Venture, in which we have a 25% ownership
interest, owned and operated a portfolio of 74 properties containing
approximately 4.9 million rentable square feet, configured in approximately
40,000 storage units and located across 13 states.
Results of Operations
When reviewing our results of operations it is important to consider the timing
of acquisition activity. We acquired 23 self storage properties during the three
months ended March 31, 2021 and 77 self storage properties during the year ended
December 31, 2020. As a result of these and other factors, we do not believe
that our historical results of operations discussed and analyzed below are
comparable or necessarily indicative of our future results of operations or cash
flows.
To help analyze the operating performance of our self storage properties, we
also discuss and analyze operating results relating to our same store portfolio.
Our same store portfolio is defined as those properties owned and operated since
the first day of the earliest year presented, excluding any properties sold,
expected to be sold or subject to significant changes such as expansions or
casualty events which cause the portfolio's year-over-year operating results to
no longer be comparable. As of March 31, 2021, our same store portfolio
consisted of 560 consolidated self storage properties.
The following discussion and analysis of the results of our operations and
financial condition should be read in conjunction with the accompanying
condensed consolidated financial statements in Item 1. Certain figures, such as
interest rates and other percentages, included in this section have been rounded
for ease of presentation. Percentage figures included in this section have not
in all cases been calculated on the basis of such rounded figures but on the
basis of such amounts prior to rounding. For this reason, percentage amounts in
this section may vary slightly from those obtained by performing the same
calculations using the figures in our condensed consolidated financial
statements or in the associated text. Certain other amounts that appear in this
section may similarly not sum due to rounding.
Three Months Ended March 31, 2021 compared to the Three Months Ended March 31,
2020
Net income was $27.6 million for the three months ended March 31, 2021, compared
to $15.8 million for the three months ended March 31, 2020, an increase of $11.8
million. The increase was primarily due to an increase in net operating income
("NOI") generated from 41 self storage properties acquired between April 1, 2020
and December 31, 2020, an additional 23 self storage properties acquired between
January 1, 2021 and March 31, 2021 and same store NOI growth, partially offset
by increases in depreciation and amortization. For a description of NOI, see
"Non-GAAP Financial Measures - NOI".

property-related revenue, management fees and other revenue, property operating
expenses, and other expenses for the three months ended March 31, 2021 compared

increase was primarily attributable to incremental revenue from 41 self storage
properties acquired between April 1, 2020 and December 31, 2020, 23 self storage
properties acquired between January 1, 2021 and March 31, 2021 and an increase
in total portfolio average occupancy from 86.7% for the three months ended March
31, 2020 to 91.8% for the three months ended March 31, 2021. 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.
Rental Revenue
Rental revenue increased by $17.7 million, or 18.6%, for the three months ended
March 31, 2021, as compared to the three months ended March 31, 2020. The
increase in rental revenue was due to a $10.5 million increase in non-same store
rental revenue which was primarily attributable to incremental rental revenue of
$7.0 million from 41 self storage properties acquired between April 1, 2020 and
December 31, 2020 and $1.4 million from 23 self storage properties acquired
during the three months ended March 31, 2021. Same store portfolio rental
revenues increased $7.2 million, or 8.0%, due to an increase in average
occupancy from 86.9% for the three months ended

                                       30
--------------------------------------------------------------------------------

March 31, 2020 to 92.5% for the three months ended March 31, 2021 and a 1.4%
increase, from $12.30 to $12.47, in annualized same store rental revenue
(including fees and net of any discounts and uncollectible customer amounts)
divided by average occupied square feet ("average annualized rental revenue per
occupied square foot"), driven primarily by increased contractual lease rates
for in-place tenants.
Other Property-Related Revenue
Other property-related revenue represents ancillary income from our self storage
properties, such as tenant insurance-related access fees and sales of storage
supplies. Other property-related revenue increased by $0.8 million, or 22.7%,
for the three months ended March 31, 2021, as compared to the three months ended
March 31, 2020. This increase primarily resulted from a $0.4 million increase in
same store other property-related revenue and a $0.3 million increase in
non-same store other property-related revenue which was primarily attributable
to incremental other property-related revenue of $0.2 million from 41 self
storage properties acquired between April 1, 2020 and December 31, 2020.
Management Fees and Other Revenue
Management fees and other revenue, which are primarily related to managing and
operating the unconsolidated real estate ventures, were $5.7 million for the
three months ended March 31, 2021, compared to $5.4 million for the three months
ended March 31, 2020, an increase of $0.3 million. This increase was primarily
attributable to increases in tenant insurance fees and dividends.
Property Operating Expenses
Property operating expenses were $34.6 million for the three months ended March
31, 2021 compared to $30.6 million for the three months ended March 31, 2020, an
increase of $4.0 million, or 13.1%. The increase in property operating expenses
primarily resulted from a $3.8 million increase in non-same store property
operating expenses that was primarily attributable to incremental property
operating expenses of $2.6 million from 41 self storage properties acquired
between April 1, 2020 and December 31, 2020 and $0.6 million from 23 self
storage properties acquired during the three months ended March 31, 2021.
General and Administrative Expenses
General and administrative expenses increased $0.1 million, or 1.3%, for the
three months ended March 31, 2021, compared to the three months ended March 31,
2020. This increase was attributable to increases in equity based compensation
expense offset by decreases in supervisory and administrative fees charged by
our PROs primarily as a result of the merger and internalization of the
management platform of SecurCare on March 31, 2020.
Depreciation and Amortization
Depreciation and amortization increased $3.3 million, or 11.4%, for the three
months ended March 31, 2021, compared to the three months ended March 31, 2020.
This increase was primarily attributable to incremental depreciation expense
related to the 41 self storage properties acquired between April 1, 2020 and
December 31, 2020 and the 23 self storage properties we acquired between January
1, 2021 and March 31, 2021, partially offset by a decrease in amortization of
customer in-place leases from $2.9 million for the three months ended March 31,
2020 to $2.4 million for the three months ended March 31, 2021.
Interest Expense
Interest expense increased $1.2 million, or 7.4%, for the three months ended
March 31, 2021, compared to the three months ended March 31, 2020. The increase
in interest expense was primarily attributable to additional borrowings in
October 2020 consisting of the issuance of $150.0 million of 2.99% senior
unsecured notes due August 5, 2030 and $100.0 million of 3.09% senior unsecured
notes due August 5, 2032.
Equity In Earnings (Losses) Of Unconsolidated Real Estate Ventures
Equity in earnings (losses) of unconsolidated real estate ventures represents
our share of earnings and losses incurred through our 25% ownership interests in
the 2018 Joint Venture and the 2016 Joint Venture. During the three months ended
March 31, 2021, we recorded $0.8 million of equity in earnings from our
unconsolidated real estate ventures compared to $0.3 million of losses for the
three months ended March 31, 2020.

                                       31
--------------------------------------------------------------------------------

Net Income Attributable to Noncontrolling Interests
As discussed in Note 2 in Item 1, we allocate GAAP income (loss) utilizing the
HLBV method, in which we allocate income or loss based on the change in each
unitholders' claim on the net assets of our operating partnership at period end
after adjusting for any distributions or contributions made during such 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 noncontrolling interests.
Net income attributable to noncontrolling interests was $6.8 million for the
three months ended March 31, 2021, compared to $9.1 million for the three months
ended March 31, 2020.
Non-GAAP Financial Measures
FFO and Core FFO
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 December 2018 Nareit Funds From Operations White Paper - 2018
Restatement, which we refer to as the White Paper, defines FFO as net income (as
determined under GAAP), excluding: real estate depreciation and amortization,
gains and losses from the sale of certain real estate assets, gains and losses
from change in control, mark-to-market changes in value recognized on equity
securities, impairment write-downs of certain real estate assets and impairment
of investments in entities when it is directly attributable to decreases in the
value of depreciable real estate held by the entity and after items to record
unconsolidated partnerships and joint ventures on the same basis. 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 purposes of calculating FFO attributable to common
shareholders, OP unitholders, and LTIP unitholders, we exclude distributions
declared on subordinated performance units, DownREIT subordinated performance
units, preferred shares and preferred units. 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.

(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(1) in the
following table 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.

(1) 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 and the treasury stock method for certain unvested LTIP units, and assumes the
conversion of vested LTIP units into OP units on a one-for-one basis and the hypothetical conversion of
subordinated performance units, and DownREIT subordinated performance 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, DownREIT
subordinated performance units and LTIP units into OP units, see Note 9 in Item 1. 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.
(2) Represents the effect of adjusting the numerator to consolidated net income (loss) prior to GAAP
allocations for noncontrolling interests, after deducting preferred share and unit distributions, and before
the application of the two-class method and treasury stock method, as described in footnote(1).


NOI


Net operating income, or NOI, represents rental revenue plus other
property-related revenue less property operating expenses. 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 for, other measures of financial performance reported in accordance
with GAAP, such as total revenues and net income (loss).

Our consolidated NOI shown in the table above does not include our proportionate
share of NOI for our unconsolidated real estate ventures. For additional
information about our 2018 Joint Venture and 2016 Joint Venture see Note 5 to
the condensed consolidated financial statements in Item 1.
EBITDA and Adjusted 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, organizational and offering expenses, equity-based
compensation expense, losses on sale of properties and impairment of long-lived
assets, minus gains on sale of properties and debt forgiveness, and after
adjustments for unconsolidated partnerships and joint ventures. 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;
•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 their usefulness as comparative measures.
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 and net
income (loss).

Adjusted EBITDA for the three months ended March 31, 2021 and 2020 (dollars in

Liquidity and Capital Resources
Liquidity Overview
Liquidity is the ability to meet present and future financial obligations. Our
primary source of liquidity is cash flow from our operations. Additional sources
are proceeds from equity and debt offerings, and debt financings including
borrowings under the credit facility, 2023 Term Loan Facility, 2028 Term Loan
Facility and 2029 Term Loan Facility.
Our short-term liquidity requirements consist primarily of property operating
expenses, property acquisitions, capital expenditures, general and
administrative expenses and principal and interest on our outstanding
indebtedness. A further short-term liquidity requirement relates to
distributions to our common and preferred shareholders and holders of preferred
units, OP units, LTIP units, subordinated performance units, DownREIT OP units
and DownREIT subordinated performance units. We expect to fund short-term
liquidity requirements from our operating cash flow, cash on hand and borrowings
under our credit facility.
Our long-term liquidity needs consist primarily of the repayment of debt,
property acquisitions, and capital expenditures. We acquire properties through
the use of cash, preferred units, OP units and subordinated performance units in
our operating partnership or DownREIT partnerships. We expect to meet our
long-term liquidity requirements with operating cash flow, cash on hand, secured
and unsecured indebtedness, and the issuance of equity and debt securities.
The availability of credit and its related effect on the overall economy may
affect our liquidity and future financing activities, both through changes in
interest rates and access to financing. Currently, interest rates are low
compared to historical levels. Our ability to access capital on favorable terms
as well as to use cash from operations to continue to meet our liquidity needs,
all of which are highly uncertain and cannot be predicted, could be affected by
various risks and uncertainties, including, but not limited to, the effects of
the COVID-19 pandemic. We believe that, as a publicly-traded REIT, we will have
access to multiple sources of capital to fund our long-term liquidity

requirements, including the incurrence of additional debt and the issuance of
debt and additional equity securities. However, we cannot assure you that this
will be the case.
Cash Flows
At March 31, 2021, we had $19.5 million in cash and cash equivalents and $3.3
million of restricted cash, an increase in cash and cash equivalents of $0.8
million and an increase in restricted cash of $0.3 million from December 31,
2020. Restricted cash primarily consists of escrowed funds deposited with
financial institutions for real estate taxes, insurance, and other reserves for
capital improvements in accordance with our loan agreements. The following
discussion relates to changes in cash due to operating, investing, and financing
activities, which are presented in our condensed consolidated statements of cash
flows included in Item 1 of this report.
Operating Activities
Cash provided by our operating activities was $64.1 million for the three ended
March 31, 2021 compared to $50.7 million for the three months ended March 31,
2020, an increase of $13.4 million. Our operating cash flow increased primarily
due to the 41 self storage properties that were acquired between April 1, 2020
and December 31, 2020 that generated cash flow for the entire three months ended
March 31, 2021, an additional 23 self storage properties acquired during the
three months ended March 31, 2021 and same store NOI growth. Because these self
storage properties were acquired after March 31, 2020, our operating results for
the three months ended March 31, 2020 were not impacted by them. The increase in
our operating cash flows was partially offset by higher cash payments for
interest expense.
Investing Activities
Cash used in investing activities was $149.4 million for the three months ended
March 31, 2021 compared to $211.1 million for the three months ended March 31,
2020. The primary uses of cash for the three months ended March 31, 2021 were
for our acquisition of 23 self storage properties for cash consideration of
$141.2 million, capital expenditures of $5.7 million, and deposits for potential
acquisitions of $2.5 million. The primary uses of cash for the three months
ended March 31, 2020 were for our acquisition of 36 self storage properties for
cash consideration of $210.0 million, capital expenditures of $4.9 million,
investments in our 2016 Joint Venture of $3.1 million, expenditures for
corporate furniture, equipment and other of $0.2 million and deposits for
potential acquisitions of $0.5 million partially offset by $7.6 million of
proceeds from the sale of equity securities.
Capital expenditures totaled $5.7 million and $4.9 million during the three
months ended March 31, 2021 and 2020, respectively. We generally fund
post-acquisition capital additions from cash provided by operating activities.
We categorize our capital expenditures broadly into three primary categories:
•recurring capital expenditures, which represent the portion of capital
expenditures that are deemed to replace the consumed portion of acquired capital
assets and extend their useful life;
•value enhancing capital expenditures, which represent the portion of capital
expenditures that are made to enhance the revenue and value of an asset from its
original purchase condition; and
•acquisitions capital expenditures, which represent the portion of capital
expenditures capitalized during the current period that were identified and
underwritten prior to a property's acquisition.

                                       37

--------------------------------------------------------------------------------



A summary of the capital expenditures for these categories, along with a
reconciliation of the total for these categories to the capital expenditures
reported in the accompanying condensed consolidated statements of cash flows for
the three months ended March 31, 2021 and 2020, are presented below (dollars in
thousands):
