The increases in FFO and Core FFO for the third quarter of 2021 and year-to-date were primarily the result of incremental NOI from properties acquired between October 1, 2020 and September 30, 2021 and same store NOI growth, partially offset by increases in subordinated performance unit distributions.

Investment Activity
During the third quarter, NSA invested approximately $599.3 million in the acquisition of 76 self storage properties consisting of approximately 5.1 million rentable square feet configured in approximately 35,644 storage units. Total consideration for these acquisitions included approximately $562.1 million of net cash, the issuance of approximately $19.9 million of OP units and $11.2 million of subordinated performance units and the assumption of approximately $6.1 million of other liabilities.
Balance Sheet
During the third quarter, the Company received approximately $40.0 million of net proceeds from the sale of 782,000 common shares under the Company's at the market (“ATM”) program. Subsequent to quarter end, the Company received approximately $7.4 million of net proceeds from the sale of 125,000 common shares under the ATM program. The Company used the net proceeds for self storage property acquisitions and to repay borrowings outstanding under its revolving line of credit. As of November 2, 2021, the Company has approximately $300.6 million of capacity remaining under its ATM program.
On May 3, 2021, the Company's operating partnership entered into an agreement to issue $180.0 million of senior unsecured notes, comprised of $35.0 million of 2.16% senior unsecured notes due May 4, 2026 (the "2026 Notes"), $90.0 million of 3.00% senior unsecured notes due May 4, 2031 (the "May 2031 Notes") and $55.0 million of 3.10% senior unsecured notes due May 4, 2033 (the "2033 Notes"). On May 26, 2021 the operating partnership issued the 2033 Notes and on July 26, 2021 the operating partnership issued the 2026 Notes and the May 2031 Notes. The Company used the proceeds to repay outstanding amounts on its revolving line of credit and for general corporate purposes.
On July 9, 2021, the Company entered into an agreement with a single lender for an $88.0 million debt financing secured by a first lien on eight of the Company's self storage properties. This interest-only loan matures in July 2028 and has a fixed interest rate of 2.77%. The Company used the proceeds to repay outstanding amounts on its revolving line of credit.
In July 2021, NSA completed an underwritten public offering of 10,120,000 common shares, including 1,320,000 common shares sold upon the exercise in full by the underwriters of their option to purchase additional common shares. The shares were issued at a price of $51.25 per share, resulting in net proceeds of approximately $497.4 million. The Company used the proceeds for self storage property acquisitions, general corporate purposes and to repay borrowings outstanding under its revolving line of credit.
On August 9, 2021, NSA entered into an amendment to its credit agreement with a syndicated group of lenders to reduce the applicable margins on its $175.0 million tranche D term loan from a range of LIBOR plus 1.50% to 2.20% to LIBOR plus 1.10% to 1.55%.
On September 21, 2021, NSA entered into an increase agreement and amendment with a syndicated group of lenders to increase the total borrowing capacity under the Company's credit facility by $125.0 million for a total credit facility of $1.4 billion, which included entry into a new $125.0 million 5.5-year term loan tranche E. NSA has an expansion option under the credit facility, which, if exercised in full, would provide for a total credit facility of $1.75 billion. The Company used the proceeds for self storage property acquisitions and for general corporate purposes.
Common Share Dividends
On August 25, 2021, NSA's Board of Trustees declared a quarterly cash dividend of $0.41 per common share, representing a 20.6% increase from the third quarter 2020. The third quarter 2021 dividend was paid on September 30, 2021 to shareholders of record as of September 15, 2021.

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 presentations 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 the Company's 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(4) 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) Represents the dilutive effect of the forward offering from the application of the treasury stock method.

(4) 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 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.
(5) 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(4).

(3) Balances exclude 252,894 long-term incentive plan ("LTIP") units which only vest and participate in dividend distributions upon the future contribution of properties from the PROs or the completion of expansion projects.
(4) 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 for certain series of subordinated performance units, and that each subordinated performance unit would on average convert on a hypothetical basis into an estimated 1.51 OP units based on historical financial information for the trailing twelve months ended September 30, 2021. 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.

(1) Values represent entire unconsolidated real estate ventures at 100%, not NSA's proportionate share. NSA's ownership in each of the unconsolidated real estate ventures is 25%.
(2) NSA's proportionate share of its unconsolidated real estate ventures is derived by applying NSA's 25% ownership interest to each line item in the GAAP financial statements of the unconsolidated real estate ventures to calculate NSA's share of that line item. NSA believes this information offers insights into the financial performance of the Company, although the presentation of such information, and its combination with NSA's consolidated results, may not accurately depict the legal and economic implications of holding a noncontrolling interest in the unconsolidated real estate ventures. The operating agreements of the unconsolidated real estate ventures provide for the distribution of net cash flow to the unconsolidated real estate ventures' investors no less than monthly, generally in proportion to the investors’ respective ownership interests, subject to a promoted distribution to NSA upon the achievement of certain performance benchmarks by the non-NSA investor.
