ORGANIZATION AND NATURE OF OPER

ORGANIZATION AND NATURE OF OPERATIONS	9 Months Ended
ORGANIZATION AND NATURE OF OPERATIONS	Sep. 30, 2022
ORGANIZATION AND NATURE OF OPERATIONS
ORGANIZATION AND NATURE OF OPERATIONS	1. ORGANIZATION AND NATURE OF OPERATIONS CubeSmart (the “Parent Company”) operates as a self-managed and self-administered real estate investment trust (“REIT”) with its operations conducted solely through CubeSmart, L.P. and its subsidiaries. CubeSmart, L.P., a Delaware limited partnership (the “Operating Partnership”), operates through an umbrella partnership structure, with the Parent Company, a Maryland REIT, as its sole general partner. In the notes to the consolidated financial statements, we use the terms “the Company”, “we” or “our” to refer to the Parent Company and the Operating Partnership together, unless the context indicates otherwise. As of September 30, 2022, the Company owned (or partially owned and consolidated) self-storage properties located in 24 states throughout the United States and the District of Columbia that are presented under one reportable segment: the Company owns, operates, develops, manages and acquires self-storage properties. As of September 30, 2022, the Parent Company owned approximately 99.4% of the partnership interests (“OP Units”) of the Operating Partnership. The remaining OP Units, consisting exclusively of limited partner interests, are held by persons who contributed their interests in properties to the Operating Partnership in exchange for OP Units. Under the partnership agreement, these persons have the right to tender their OP Units for redemption to the Operating Partnership at any time following a specified restricted period for cash equal to the fair value of an equivalent number of common shares of the Parent Company. In lieu of delivering cash, however, the Parent Company, as the Operating Partnership’s general partner, may, at its option, choose to acquire any OP Units so tendered by issuing common shares in exchange for the tendered OP Units. If the Parent Company so chooses, its common shares will be exchanged for OP Units on a one-for-one basis. This one-for-one exchange ratio is subject to adjustment to prevent dilution. With each such exchange or redemption, the Parent Company’s percentage ownership in the Operating Partnership will increase. In addition, whenever the Parent Company issues common or other classes of its shares, it contributes the net proceeds it receives from the issuance to the Operating Partnership and the Operating Partnership issues to the Parent Company an equal number of OP Units or other partnership interests having preferences and rights that mirror the preferences and rights of the shares issued. This structure is commonly referred to as an umbrella partnership REIT or “UPREIT”. The Company typically experiences seasonal fluctuations in the occupancy levels of its stores, which are generally slightly higher during the summer months due to increased moving activity.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting and, in the opinion of each of the Parent Company’s and Operating Partnership’s respective management, include all adjustments (consisting of normal recurring adjustments) necessary for a fair presentation of financial position, results of operations and cash flows for each respective company for the interim periods presented in accordance with generally accepted accounting principles in the United States (“GAAP”). Accordingly, readers of this Quarterly Report on Form 10-Q should refer to the Parent Company’s and the Operating Partnership’s combined audited financial statements prepared in accordance with GAAP, and the related notes thereto, for the year ended December 31, 2021, which are included in the Parent Company’s and the Operating Partnership’s combined Annual Report on Form 10-K for the fiscal year ended December 31, 2021 The Operating Partnership meets the criteria as a variable interest entity (“VIE”). The Parent Company’s sole significant asset is its investment in the Operating Partnership. As a result, substantially all of the Parent Company’s assets and liabilities represent those assets and liabilities of the Operating Partnership. All of the Parent Company’s debt is an obligation of the Operating Partnership, and the Parent Company guarantees the unsecured debt obligations of the Operating Partnership. Recent Accounting Pronouncements In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2020-04 – Reference Rate Reform (Topic 848), providing optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. In January 2021, the FASB issued ASU No. 2021-01 – Reference Rate Reform (Topic 848): Scope to Clarify the Guidance Offered by Topic 848. ASU No. 2020-04 and ASU No. 2021-01 are applicable to contracts, hedging relationships, and other transactions that reference the London Inter-bank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued due to reference rate reform. This optional guidance may be applied prospectively as of January 1, 2020 through December 31, 2024. To date, the Company has not adopted the optional guidance and does not expect that any future adoption will have a material impact on the Company’s consolidated financial statements. In August 2020, the FASB issued ASU No. 2020-06 – Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in an Entity’s Own Equity (Subtopic 815-40). The new guidance eliminates the beneficial conversion and cash conversion accounting models for convertible instruments. It also amends the accounting for certain contracts in an entity’s own equity that are currently accounted for as derivatives because of certain settlement provisions. In addition, the new guidance modifies how particular convertible instruments and certain contracts that may be settled in cash or shares impact the diluted earnings per share computation. The standard was effective on January 1, 2022. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements.

INVESTMENT ACTIVITY 2022 Acquisitions During the nine months ended September 30, 2022, the Company acquired three stores located in Georgia (1) , Maryland (1) and Texas (1) for an aggregate purchase price of $75.7 million. In connection with these transactions, which were accounted for as asset acquisitions, the Company allocated the purchase price and acquisition-related costs to the tangible and intangible assets acquired based on fair value. Intangible assets consisted of in-place leases, which aggregated to $3.4 million at the time of the acquisition and prior to amortization of such amounts. The estimated life of these in-place leases is 12 months and the amortization expense that was recognized during the three and nine months ended September 30, 2022 was approximately $0.9 million and $1.4 million, respectively. Additionally, on February 2, 2022, the Company acquired land underlying a wholly-owned store located in Bronx, New York for $7.5 million. The land was previously subject to a ground lease in which the Company served as lessee. As a result of the transaction, which was accounted for as an asset acquisition, the Company was released from its obligations under the ground lease, and the right-of-use asset and lease liability totaling $4.1 million and $5.0 million, respectively, were removed from the Company’s consolidated balance sheets. Also, on April 28, 2022, the Company acquired land underlying a store owned by 191 IV CUBE LLC, an unconsolidated joint venture in which the Company holds a 20% ownership interest (see note 5). The purchase price for the land was $6.1 million, and the Company now serves as the lessor in a ground lease of the land to 191 IV CUBE LLC. 2022 Dispositions During the nine months ended September 30, 2022, the Company sold the Los Angeles Athletic Club, which it purchased in December 2021 as part of the LAACO acquisition, for $44.0 million. No gain or loss was recognized in conjunction with the sale. LAACO Acquisition On December 9, 2021, the Company acquired all outstanding partnership units of LAACO, the owner of the Storage West Assets and, as a result, LAACO became a wholly-owned subsidiary of the Company. The 57 Storage West Assets are located in Arizona (17), California (20), Nevada (13) and Texas (7). Through its acquisition of LAACO, the Company also acquired a 50% interest in two separate unconsolidated joint ventures, each of which own one storage property in California (see note 5). In addition, through this acquisition, the Company also acquired the Club Operations, which included the Los Angeles Athletic Club (consisting of athletic facilities, food and beverage operations and a hotel) and the California Yacht Club (the “CYC”) (consisting of sports facilities, food and beverage operations and a marina). During the nine months ended September 30, 2022, the Company sold the Los Angeles Athletic Club (see above). As of September 30, 2022, the CYC is classified as held for sale on the Company’s consolidated balance sheets. The following summarizes the relevant components contemplated in the acquisition of LAACO: Amount (in thousands) Costs contemplated: Capitalized costs: LAACO partnership units (1) $ 1,648,426 Long-term debt assumed and repaid at closing 40,880 Payments to LAACO management (capitalized) (2) 16,807 Other transaction costs (3) 13,407 Total capitalized costs $ 1,719,520 Payments and anticipated payments to LAACO management (expensed) (2) 25,144 Total costs contemplated $ 1,744,664 Estimated fair value of Club Operations $ 46,800 (1) Represents the acquisition of all 167,557 outstanding partnership units for $9,838 per unit. (2) Upon the acquisition of LAACO, the Company assumed severance obligations payable to certain employees pursuant to pre-existing agreements. Based on the specific details of the arrangements, $16.8 million in costs were capitalized to the basis of the acquired properties while $25.1 million were considered post-combination compensation expenses. Of this $25.1 million, $14.8 million was included in the component of other income (expense) designated as other for the year ended December 31, 2021. Amounts of $10.3 million were included in the component of other income (expense) designated as other for the nine months ended September 30, 2022. (3) Includes consulting fees, legal fees, and other costs. The Company accounted for the acquisition of LAACO as an asset acquisition. As a result, the capitalized costs noted above were allocated to LAACO’s real estate assets, intangible assets and real estate venture investments on a relative fair value basis. All other assets acquired and liabilities assumed were recorded at fair value. The following summarizes the accounting for the LAACO acquisition: Amount (in thousands) Storage properties $ 1,517,243 Cash and cash equivalents 18,291 Investment in real estate ventures, at equity 35,737 Assets held for sale 50,435 Other assets, net 143,599 Accounts payable, accrued expenses and other liabilities (38,350) Deferred revenue (3,764) Security deposits (36) Liabilities held for sale (3,635) Total $ 1,719,520 Intangible assets (included above in Other assets, net) consisted of in-place leases, which aggregated to $109.7 million at the time of the acquisition and prior to amortization of such amounts. The estimated life of these in-place leases is 12 months and the amortization expense that was recognized during the three and nine months ended September 30, 2022 was approximately $27.4 million and $82.2 million, respectively. Other 2021 Acquisitions During the year ended December 31, 2021, the Company also acquired eight additional stores located in Florida ( 1 ), Georgia ( 1 ), Illinois ( 1 ), Maryland ( 1 ), Nevada ( 1 ), New Jersey ( 1 ) and Pennsylvania ( 2 ) for an aggregate purchase price of approximately $140.8 million. In addition, a consolidated joint venture in which the Company holds a 50% interest acquired a store in Minnesota for a purchase price of $12.0 million (see note 13). In connection with these transactions, which were accounted for as asset acquisitions, the Company allocated the purchase price and acquisition-related costs to the tangible and intangible assets acquired based on fair value. Intangible assets consisted of in-place leases, which aggregated to $11.9 million at the time of the acquisitions and prior to amortization of such amounts. The estimated life of these in-place leases is 12 months and the amortization expense that was recognized during the three and nine months ended September 30, 2022 was approximately $1.7 million and $7.5 million, respectively. 2021 Dispositions During the year ended December 31, 2021, the Company sold five properties located in Colorado (1), Nevada (1), North Carolina (2) and Texas (1) for an aggregate sales price of $43.8 million. In conjunction with the sales, the Company recorded gains that totaled $32.7 million. Assets Held for Sale As of September 30, 2022, the Company determined that the CYC met the criteria to be classified as held for sale. Accordingly, the assets and liabilities associated with the CYC have been categorized as held for sale within the Company’s consolidated balance sheets. As of September 30, 2022, the estimated fair value less selling costs of the CYC was greater than the carrying value of the CYC, and therefore no loss has been recorded in the current period. Development Activity As of September 30, 2022, the Company had an investment in a joint venture to develop one self-storage property located in New York. Construction for this project is expected to be completed by the fourth quarter of 2023 (see note 13). As of September 30, 2022, development costs incurred to date for this project totaled $22.3 million. Total construction costs for this project are expected to be $46.2 million. These costs are capitalized to construction in progress while the project is under development and are reflected in Storage properties on the Company’s consolidated balance sheets. The Company has completed the construction and opened for operation the following stores during the period January 1, 2021 through September 30, 2022. The costs associated with the construction of these stores are capitalized to land, building and improvements, as well as equipment and are reflected in Storage properties on the Company’s consolidated balance sheets. CubeSmart Number of Ownership Total Store Location Stores Date Opened Interest Construction Costs (in thousands) Valley Stream, NY 1 Q3 2022 51% $ 39,000 Vienna, VA (1) 1 Q2 2022 80% 21,800 Newton, MA (2) 1 Q4 2021 100% 20,800 East Meadow, NY (3) 1 Q2 2021 100% 25,900 King of Prussia, PA 1 Q2 2021 70% 22,800 Arlington, VA (1) 1 Q1 2021 90% 26,400 6 $ 156,700 (1) Each of these stores are located adjacent to an existing consolidated joint venture store. Given this proximity, each of these stores has been combined with the adjacent existing store in our store count upon opening, as well as for operational and reporting purposes (see note 13). (2) During the fourth quarter of 2021, the Company, through a joint venture in which it owned a 90% interest that was previously consolidated, completed the construction of this store and it was opened for operation. On December 14, 2021, the Company acquired the 10% interest of the noncontrolling member in the venture that owned the store for $3.4 million. Prior to this transaction, the noncontrolling member’s interest in the venture was reported in Noncontrolling interests in subsidiaries on the consolidated balance sheets. Since the Company retained its controlling interest in the venture and the store is now wholly owned, this transaction was accounted for as an equity transaction. The carrying amount of the noncontrolling interest was reduced to zero to reflect the purchase and the difference between the purchase price paid by the Company and the carrying amount of the noncontrolling interest of $2.7 million was recorded as an adjustment to equity attributable to the Company, with no gain or loss recorded. The $13.2 million related party loan extended by the Company to the venture that owned the store was repaid in conjunction with the Company’s acquisition of the noncontrolling member’s ownership interest. (3) This store was previously owned by a consolidated joint venture, in which the Company held a 51% ownership interest. On June 29, 2021, the noncontrolling member in the venture that owned the store put its 49% interest in the venture to the Company for $6.6 million in cash consideration.

Based upon the facts and circumstances at acquisition of Fontana and RCSS and formation of HVP V, HVPSE, HVP IV, HHFNE and HHF (the “Ventures”), the Company determined that the Ventures are not VIEs in accordance with the accounting standard for the consolidation of VIEs. As a result, the Company used the voting interest model under the accounting standard for consolidation in order to determine whether to consolidate the Ventures. Based upon each member's substantive participating rights over the activities of each entity as stipulated in the operating agreements, the Ventures are not consolidated by the Company and are accounted for under the equity method of accounting. The Company’s investments in the Ventures are included in Investment in real estate ventures, at equity on the Company’s consolidated balance sheets and the Company’s earnings from its investments in the Ventures are presented in Equity in earnings of real estate ventures on the Company’s consolidated statements of operations.

The indenture under which the Senior Notes were issued restricts the ability of the Operating Partnership and its subsidiaries to incur debt unless the Operating Partnership and its consolidated subsidiaries comply with a leverage ratio not to exceed 60% and an interest coverage ratio of more than 1.5 :1.0 after giving effect to the incurrence of the debt. The indenture also restricts the ability of the Operating Partnership and its subsidiaries to incur secured debt unless the Operating Partnership and its consolidated subsidiaries comply with a secured debt leverage ratio not to exceed 40% after giving effect to the incurrence of the debt. The indenture also contains other financial and customary covenants, including a covenant not to own unencumbered assets with a value less than 150% of the unsecured indebtedness of the Operating Partnership and its consolidated subsidiaries. As of September 30, 2022, the Operating Partnership was in compliance with all of the financial covenants under the Senior Notes.

RISK MANAGEMENT AND USE OF FINANCIAL INSTRUMENTS	Sep. 30, 2022
RISK MANAGEMENT AND USE OF FINANCIAL INSTRUMENTS
RISK MANAGEMENT AND USE OF FINANCIAL INSTRUMENTS	11. RISK MANAGEMENT AND USE OF FINANCIAL INSTRUMENTS The Company’s use of derivative instruments is limited to the utilization of interest rate swap agreements or other instruments to manage interest rate risk exposure and not for speculative purposes. The principal objective of such arrangements is to minimize the risks and/or costs associated with the Company’s operating and financial structure, as well as to hedge specific transactions. The counterparties to these arrangements are major financial institutions with which the Company and its subsidiaries may also have other financial relationships. The Company is potentially exposed to credit loss in the event of non-performance by these counterparties. However, because of the high credit ratings of the counterparties, the Company does not anticipate any of the counterparties will fail to meet these obligations as they come due. The Company does not hedge credit or property value market risks. The Company formally assesses, both at inception of a hedge and on an on-going basis, whether each derivative is highly-effective in offsetting changes in cash flows of the hedged item. If management determines that the derivative is highly-effective as a hedge, then the Company accounts for the derivative using hedge accounting, pursuant to which gains or losses inherent in the derivative do not impact the Company’s results of operations. If management determines that the derivative is not highly-effective as a hedge or if a derivative ceases to be a highly-effective hedge, the Company discontinues hedge accounting prospectively and reflects in its statement of operations realized and unrealized gains and losses with respect to the derivative. As of September 30, 2022 and December 31, 2021, all derivative instruments entered into by the Company had been settled. On December 24, 2018, the Company entered into interest rate swap agreements with notional amounts that aggregated to $150.0 million (the “Interest Rate Swaps”) to protect the Company against adverse fluctuations in interest rates by reducing exposure to variability in cash flows relating to interest payments on a forecasted issuance of long-term debt. The Interest Rate Swaps qualified and were designated as cash flow hedges. Accordingly, the Interest Rate Swaps were recorded on the consolidated balance sheet at fair value and the related gains or losses were deferred in shareholders’ equity as accumulated other comprehensive income or loss. These deferred gains and losses were amortized into interest expense during the period or periods in which the related interest payments affected earnings. On January 24, 2019, in conjunction with the issuance of its 4.375% senior notes due 2029 (the “2029 Notes”), the Company settled the Interest Rate Swaps for $0.8 million. The $0.8 million termination premium will be reclassified from accumulated other comprehensive loss as an increase to interest expense over the life of the 2029 Notes, which mature on February 15, 2029. The change in unrealized losses on interest rate swaps reflects a reclassification of twenty thousand dollars and sixty thousand dollars of unrealized losses from accumulated other comprehensive loss as an increase to interest expense during the three and nine months ended September 30, 2022. The Company estimates that $0.1 million will be reclassified as an increase to interest expense in the next 12 months.

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS	9 Months Ended
FAIR VALUE MEASUREMENTS	Sep. 30, 2022
FAIR VALUE MEASUREMENTS
FAIR VALUE MEASUREMENTS	12. FAIR VALUE MEASUREMENTS The Company applies the methods of determining fair value as described in authoritative guidance, to value its financial assets and liabilities. As defined in the guidance, fair value is based on the price that would be received from the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In order to increase consistency and comparability in fair value measurements, the guidance establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three broad levels, which are described below: Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs. Level 2: Observable prices that are based on inputs not quoted on active markets, but corroborated by market data. Level 3: Unobservable inputs are used when little or no market data is available. The fair value hierarchy gives the lowest priority to Level 3 inputs. In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs, to the extent possible, as well as considering counterparty credit risk in its assessment of fair value. There were no financial assets or liabilities carried at fair value as of September 30, 2022 or December 31, 2021. The fair values of financial instruments, including cash and cash equivalents, restricted cash, accounts receivable and accounts payable approximate their respective carrying values at September 30, 2022 and December 31, 2021. The following table summarizes the carrying value and estimated fair value of the Company’s debt as of September 30, 2022 and December 31, 2021: September 30, 2022 December 31, 2021 (in thousands) Carrying value $ 3,021,431 $ 3,145,785 Fair value 2,570,180 3,256,128 The fair value of debt estimates were based on a discounted cash flow analysis assuming market interest rates for comparable obligations at September 30, 2022 and December 31, 2021. The Company estimates the fair value of its fixed-rate debt and the credit spreads over variable market rates on its variable-rate debt by discounting the future cash flows of each instrument at estimated market rates or credit spreads consistent with the maturity of the debt obligation with similar credit policies, which is classified within level 2 of the fair value hierarchy. Rates and credit spreads take into consideration general market conditions and maturity.

The following table summarizes the Company’s consolidated joint ventures, each of which are accounted for as VIEs (dollars in thousands): CubeSmart Number Date Opened / Ownership September 30, 2022 Consolidated Joint Ventures of Stores Location Acquired (1) Interest Total Assets Total Liabilities (in thousands) Astoria Investors, LLC ("Astoria") (2) 1 Queens, NY Q4 2023 (est.) 70% $ 22,595 $ 7,991 CS 750 W Merrick Rd, LLC ("Merrick") (3) 1 Valley Stream, NY Q3 2022 51% 37,625 17,255 CS Vienna, LLC ("Vienna") (4) 1 Vienna, VA Q2 2022 80% 32,944 35,160 CS Valley Forge Village Storage, LLC ("VFV") (5) 1 King of Prussia, PA Q2 2021 70% 20,667 14,633 CS Lock Up Anoka, LLC ("Anoka") (6) 1 Anoka, MN Q2 2021 50% 11,141 5,615 SH3, LLC ("SH3") (7) 1 Arlington, VA Q2 2015/Q1 2021 90% 38,141 262 6 $ 163,113 $ 80,916 (1) All consolidated joint ventures were formed to develop, own and operate new stores with the exception of Anoka, which was formed to acquire an existing store that had commenced operations. (2) On August 17, 2021, the Company contributed $14.7 million in exchange for a 70% ownership interest in Astoria, which acquired land for future development of a self-storage property in Queens, NY for $20.0 million. As of September 30, 2022, the Company has funded $7.7 million of a $27.1 million related party loan commitment to Astoria, which is included in total liabilities within the table above. This loan and the related interest were eliminated for consolidation purposes. (3) During the three months ended September 30, 2022, the noncontrolling member of Merrick notified the Company that it intends to exercise its option to put its ownership interest in the venture to the Company for $17.1 million (the “Put Option”). The Company, at its sole discretion, may pay cash and/or issue OP Units in exchange for the noncontrolling member’s interest. This transaction is expected to be completed subsequent to September 30, 2022. The Company accreted the liability related to the Put Option during the development period and, as of September 30, 2022, has accrued the full $17.1 million. This amount is included in Accounts payable, accrued expenses and other liabilities on the Company’s consolidated balance sheets and in total liabilities within the table above. (4) On December 23, 2020, the Company and the noncontrolling member contributed a previously wholly-owned operating property (the “Vienna Operating Property”) and a parcel of land (the “Vienna Land”), respectively, to Vienna. The Vienna Operating Property and the Vienna Land are located in close proximity to each other in Vienna, VA. In June 2022, the members completed construction of a new store on the Vienna Land. Upon completion, the new store was combined with the Vienna Operating Property and is now operated by the venture as a single store. As of September 30, 2022, the Company has an outstanding loan of $34.9 million to Vienna. The loan is included in total liabilities within the table above. This loan and the related interest were eliminated for consolidation purposes. (5) The Company has a related party loan commitment to VFV that was used to fund a portion of the construction costs. As of September 30, 2022, the Company has an outstanding loan of $14.6 million to VFV, which is included in total liabilities within the table above. This loan and the related interest were eliminated for consolidation purposes. (6) On April 16, 2021, the Company contributed $3.4 million in exchange for a 50% ownership interest in Anoka, which acquired a self-storage property located in Minnesota for $12.0 million. In addition, as of September 30, 2022, the Company has funded $5.5 million of a $6.1 million related party loan commitment to Anoka, which is included in total liabilities within the table above. This loan and the related interest were eliminated for consolidation purposes. (7) SH3 owns two stores located in close proximity to each other in Arlington, VA, the first of which was developed and opened for operation in April 2015 (“Shirlington I”) and the second of which was developed and opened for operation in March 2021 (“Shirlington II”). Given their close proximity to each other, the two stores were combined in our store count, as well as for operational and reporting purposes, upon the opening of Shirlington II in March 2021. Operating Partnership Ownership The Company follows guidance regarding the classification and measurement of redeemable securities. Under this guidance, securities that are redeemable for cash or other assets, at the option of the holder and not solely within the control of the issuer, must be classified outside of permanent equity/capital. This classification results in certain outside ownership interests being included as redeemable noncontrolling interests outside of permanent equity/capital in the consolidated balance sheets. The Company makes this determination based on terms in applicable agreements, specifically in relation to redemption provisions. Additionally, with respect to redeemable ownership interests in the Operating Partnership held by third parties for which CubeSmart has a choice to settle the redemption by delivery of its own shares, the Operating Partnership considered the guidance regarding accounting for derivative financial instruments indexed to, and potentially settled in, a company’s own shares, to evaluate whether CubeSmart controls the actions or events necessary to presume share settlement. The guidance also requires that noncontrolling interests classified outside of permanent capital be adjusted each period to the greater of the carrying value based on the accumulation of historical cost or the redemption value. Approximately 0.6% and 0.8% of the outstanding OP Units, as of September 30, 2022 and December 31, 2021, respectively, were not owned by CubeSmart, the sole general partner. The interests in the Operating Partnership represented by these OP Units were a component of the consideration that the Operating Partnership paid to acquire certain self-storage properties. The holders of the OP Units are limited partners in the Operating Partnership and have the right to require CubeSmart to redeem all or part of their OP Units for, at the general partner’s option, an equivalent number of common shares of CubeSmart or cash based upon the fair value of an equivalent number of common shares of CubeSmart. However, the partnership agreement contains certain provisions that could result in a settlement outside the control of CubeSmart and the Operating Partnership, as CubeSmart does not have the ability to settle in unregistered shares. Accordingly, consistent with the guidance, the Operating Partnership will record the OP Units owned by third parties outside of permanent capital in the consolidated balance sheets. Net income or loss related to the OP Units owned by third parties is excluded from net income or loss attributable to Operating Partner in the consolidated statements of operations. As of September 30, 2022 and December 31, 2021, 1,460,520 and 1,901,595 OP units, respectively, were held by third parties. The per unit cash redemption amount of the outstanding OP units was calculated based upon the closing price of the common shares of CubeSmart on the New York Stock Exchange on the final trading day of the quarter. Based on the Company’s evaluation of the redemption value of the redeemable noncontrolling interest, the Company has reflected these interests at the greater of the carrying value based on the accumulation of historical cost or the redemption value at September 30, 2022 and December 31, 2021.

COMMITMENTS AND CONTINGENCIES
COMMITMENTS AND CONTINGENCIES	14. COMMITMENTS AND CONTINGENCIES Litigation The Company is involved in claims from time to time, which arise in the ordinary course of business. In accordance with applicable accounting guidance, management establishes an accrued liability for claim expenses, insurance retention and litigation costs when those matters present loss contingencies that are both probable and reasonably estimable. In such cases, there may be exposure to loss in excess of those amounts accrued. The estimated loss, if any, is based upon currently available information and is subject to significant judgment, a variety of assumptions, and known and unknown uncertainties. In the opinion of management, the Company has made adequate provisions for potential liabilities, arising from any such matters, which are included in Accounts payable, accrued expenses and other liabilities on the Company’s consolidated balance sheets. Insurance Recovery The Company incurred damages at certain stores due to Hurricane Ian, which made landfall in Florida on September 28, 2022. The Company maintains insurance coverage for property losses subject to certain deductibles and self-insured retentions. While the Company reasonably expects that applicable insurance proceeds will cover the replacement cost of the damaged stores, there is no assurance that the insurance proceeds will be sufficient to cover all of the restoration costs. During the three months ended September 30, 2022, the Company recorded $1.6 million in charges based on an initial damage assessment of the damaged stores and the terms of the deductibles associated with the applicable insurance policies. These estimated charges are included in Property operating expenses in the Company’s consolidated statements of operations. To the extent that insurance proceeds, which are on a replacement cost basis, ultimately exceed the net book value of the damaged assets, a gain will be recognized in the period in which all contingencies related to the insurance claim have been resolved.

The Company believes that all of these related-party receivables are fully collectible. The HVP V, HVPSE, HVP IV and HHFNE operating agreements provide for acquisition, disposition and other fees payable from HVP V, HVPSE, HVP IV and HHFNE to the Company upon the closing of a property transaction by HVP V, HVPSE, HVP IV and HHFNE or any of their subsidiaries and completion of certain measures as defined in the operating agreements.

This optional guidance may be applied prospectively as of January 1, 2020 through December 31, 2024. To date, the Company has not adopted the optional guidance and does not expect that any future adoption will have a material impact on the Company’s consolidated financial statements. In August 2020, the FASB issued ASU No. 2020-06 – Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in an Entity’s Own Equity (Subtopic 815-40). The new guidance eliminates the beneficial conversion and cash conversion accounting models for convertible instruments. It also amends the accounting for certain contracts in an entity’s own equity that are currently accounted for as derivatives because of certain settlement provisions. In addition, the new guidance modifies how particular convertible instruments and certain contracts that may be settled in cash or shares impact the diluted earnings per share computation. The standard was effective on January 1, 2022. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements.

Given this proximity, each of these stores has been combined with the adjacent existing store in our store count upon opening, as well as for operational and reporting purposes (see note 13). (2) During the fourth quarter of 2021, the Company, through a joint venture in which it owned a 90% interest that was previously consolidated, completed the construction of this store and it was opened for operation. On December 14, 2021, the Company acquired the 10% interest of the noncontrolling member in the venture that owned the store for $3.4 million. Prior to this transaction, the noncontrolling member’s interest in the venture was reported in Noncontrolling interests in subsidiaries on the consolidated balance sheets. Since the Company retained its controlling interest in the venture and the store is now wholly owned, this transaction was accounted for as an equity transaction. The carrying amount of the noncontrolling interest was reduced to zero to reflect the purchase and the difference between the purchase price paid by the Company and the carrying amount of the noncontrolling interest of $2.7 million was recorded as an adjustment to equity attributable to the Company, with no gain or loss recorded. The $13.2 million related party loan extended by the Company to the venture that owned the store was repaid in conjunction with the Company’s acquisition of the noncontrolling member’s ownership interest. (3) This store was previously owned by a consolidated joint venture, in which the Company held a 51% ownership interest. On June 29, 2021, the noncontrolling member in the venture that owned the store put its 49% interest in the venture to the Company for $6.6 million in cash consideration.
