Any material change to these assumptions may result in a significantly higher or lower fair value of the Deferred Purchase Obligation. The change in value of the Deferred Purchase Obligation during the three months ended September 30,March 31, 2023 was driven by the accretion of the obligation to present value.

3. ACQUISITIONS
ITRENEW ACQUISITIONPRO FORMA FINANCIAL INFORMATION
On January 25, 2022, in order to expand our ALMasset lifecycle management operations, we acquired an approximately 80% interest in Intercept Parent, Inc. ("ITRenew")ITRenew at an agreed upon purchase price of $725,000, subject to certain working capital adjustments at, and subsequent to, the closing (the "ITRenew Transaction"). At closing, we paid $748,846 and acquired $30,720 of cash on hand, for a net purchase price of $718,126 for the ITRenew Transaction. The acquisition agreement provides us the option to purchase, and provides the shareholders of ITRenew the option to sell, the remaining approximately 20% interest in ITRenew as follows: (i) approximately 16% on or after the second anniversary of the ITRenew Transaction and (ii) approximately 4% on or after the third anniversary of the ITRenew Transaction (collectively, the "Remaining Interests"). The total payments for the Remaining Interests, based on the achievement of certain targeted performance metrics, will be no less than $200,000 and no more than $531,000 (the "Deferred Purchase Obligation"). The maximum amount of the Deferred Purchase Obligation would require achievement of the targeted performance metrics at approximately two times the level that is assumed in our fair value estimate of the Deferred Purchase Obligation of $275,100. From January 25, 2022, we consolidate 100% of the revenues and expenses associated with this business. The Deferred Purchase Obligation is reflected as a long-term liability in our Condensed Consolidated Balance Sheet at September 30, 2022, and, accordingly, we have not reflected any non-controlling interests associated with the ITRenew Transaction as the Remaining Interests have non-substantive equity interest rights. Subsequent increases or decreases in the fair value estimate of the Deferred Purchase Obligation will be included as a component of Other (income) expense, net in our Consolidated Statements of Operations until the Deferred Purchase Obligation is settled or paid. ITRenew is presented in Corporate and Other Business (as disclosed in Note 9) and primarily operates in the United States.

The letters of credit expire at various dates between October 2022June 2023 and January 2033.July 2025.
DEBT COVENANTS
The Credit Agreement, our bond indentures and other agreements governing our indebtedness contain certain restrictive financial and operating covenants, including covenants that restrict our ability to complete acquisitions, pay cash dividends, incur indebtedness, make investments, sell assets and take other specified corporate actions. The covenants do not contain a rating trigger. Therefore, a change in our debt rating would not trigger a default under the Credit Agreement, our bond indentures or other agreements governing our indebtedness. The Credit Agreement requires that we satisfy a fixed charge coverage ratio and a net total lease adjusted leverage ratio and a fixed charge coverage ratio on a quarterly basis and our bond indentures require that, among other things, we satisfy a leverage ratio (not lease adjusted) or a fixed charge coverage ratio (not lease adjusted), as a condition to taking actions such as paying dividends and incurring indebtedness.
The Credit Agreement uses earnings before interest, taxes, depreciation and amortization and rent expense ("EBITDAR") based calculations and the bond indentures use EBITDAearnings before interest, taxes, depreciation and amortization ("EBITDA") based calculations as the primary measures of financial performance for purposes of calculating leverage and fixed charge coverage ratios. The EBITDAR- and EBITDA-based leverage calculations include our consolidated subsidiaries, other than those we have designated as "Unrestricted Subsidiaries" as defined in the Credit Agreement and bond indentures. Generally, the Credit Agreement and the bond indentures use a trailing four fiscal quarter basis for purposes of the relevant calculations and require certain adjustments and exclusions for purposes of those calculations, which make the calculation of financial performance for purposes of those calculations under the Credit Agreement and bond indentures not directly comparable to Adjusted EBITDA as presented herein. We are in compliance with our leverage and fixed charge coverage ratios under the Credit Agreement, our bond indentures and other agreements governing our indebtedness as of September 30, 2022 and DecemberMarch 31, 2021.2023. Noncompliance with these leverage and fixed charge coverage ratios would have a material adverse effect on our financial condition.condition and liquidity.

7. COMMITMENTS AND CONTINGENCIES
We are involved in litigation from time to time in the ordinary course of business, including litigation arising from damage to customer assets in our facilities caused by fires and other natural disasters. While the outcome of such litigation is inherently uncertain, we do not believe any current litigation will have a material adverse effect on our consolidated financial condition, results of operations or cash flows.
We have estimated a reasonably possible range for all loss contingencies and believe it is reasonably possible that we could incur aggregate losses in addition to amounts currently accrued for all matters up to an additional $24,000$20,500 over the next several years, of which certain amounts would be covered by insurance or indemnity arrangement.

In October 2019, we announced our global program designedSee Note 11 to better position us for future growth and achievement of our strategic objectives ("Project Summit") which we completed as of December 31, 2021. Project Summit has improved annual Adjusted EBITDA (as defined below) by approximately $375.0 million exiting 2021, of which approximately $160.0 million and $165.0 million were realized in 2021 and 2020, respectively, with the remainder realized during 2022.
ACQUISITION OF ITRENEW
On January 25, 2022, in orderNotes to expand our asset lifecycle management ("ALM") operations, we acquired an approximately 80% interest in Intercept Parent, Inc. ("ITRenew"). From January 25, 2022, we consolidate 100% of the revenues and expenses associated with this business. ITRenew is presented in Corporate and Other Business and primarily operates in the United States. See Acquisitions within the Liquidity and Capital Resources section below for additional information.
DIVESTMENTS AND DECONSOLIDATIONS
IPM DIVESTMENT
On June 7, 2021, we sold our Intellectual Property Management ("IPM") business, also known as our technology escrow services business, which we predominantly operated in the United States, for total gross consideration of approximately $215.4 million (the "IPM Divestment"). We have concluded that the IPM Divestment does not meet the criteria to be reported as discontinued operations in our consolidated financial statements, as our decision to divest this business does not represent a strategic shift that will have a major effect on our operations and financial results. Accordingly, the revenues and expenses associated with this business are presented as a component of Operating income (loss) in our Condensed Consolidated Financial Statements of Operations through the date of divestment and the cash flows associated with this business is presented as a component of cash flows from operations in our Condensed Consolidated Statements of Cash Flows through the date of divestment. Our IPM business represented approximately $14.2 million of total revenues and approximately $6.8 million of total net income from January 1, 2021 through the date of divestment on June 7, 2021.
DECONSOLIDATIONS
On March 24, 2022, as a result of our loss of control, we deconsolidated the businesses included in the acquisition of OSG Records Management (Europe) Limited, excluding Ukraine. We recognized a loss of approximately $105.8 million associated with the deconsolidation to Other expense (income), net in the first quarter of 2022 representing the difference between the net asset value prior to the deconsolidationthis Quarterly Report for more information on Restructuring and the subsequent remeasurement of the retained investment to a fair value of zero. We have concluded that the deconsolidation does not meet the criteria to be reported as discontinued operations in our consolidated financial statements, as it does not represent a strategic shift that will have a major effect on our operations and financial results. Accordingly, the revenues and expenses associated with these businesses are presented as a component of Operating income (loss) in our Condensed Consolidated Statements of Operations through the date of deconsolidation and the cash flows associated with these businesses are presented as a component of Cash flows from operations in our Condensed Consolidated Statements of Cash Flows through the date of the deconsolidation. These businesses represented approximately $44.9 million of total revenues and $7.2 million of total net income for the year ended December 31, 2021.other transformation costs.

RESULTS OF OPERATIONS - KEY TRENDS
We have experienced steady volume in our Global RIM Business segment, with organic storage rental revenue growth driven primarily by revenue management. We expect organic storage rental revenue growth to benefit from revenue management and volume to be relatively stable in the near term.
Our organic service revenue growth is primarily due to increases in our service activity. We expect organic service revenue growth for the remainder of 2022 and intoin 2023 to benefit from our new and existing digital offerings, as well as our traditional services.
Weexpect continued total revenue and Adjusted EBITDA growth in 2022 and into 2023 as a result of our focus on new product and service offerings, innovation, customer solutions and market expansion in line with our Project Matterhorn objectives.

Adjusted EBITDA excludes both interest expense, net and the provision (benefit) for income taxes. These expenses are associated with our capitalization and tax structures, which we do not consider when evaluating the operating profitability of our core operations. Adjusted EBITDA does not include depreciation and amortization expenses, in order to eliminate the impact of capital investments, which we evaluate by comparing capital expenditures to incremental revenue generated and as a percentage of total revenues. Adjusted EBITDA and Adjusted EBITDA Margin should be considered in addition to, but not as a substitute for, other measures of financial performance reported in accordance with accounting principles generally accepted in the United States of America ("GAAP"), such as operating income, net income (loss) or cash flows from operating activities (as determined in accordance with GAAP).activities.

We believe Adjusted EPS is of value to our current and potential investors when comparing our results from past, present and future periods.

(1)The difference between our effective tax rates and our structural tax rate (or adjusted effective tax rates) for the three and nine months ended September 30,March 31, 2023 and 2022 and 2021 is primarily due to (i) the reconciling items above, which impact our reported net income (loss) before provision (benefit) for income taxes but have an insignificant impact on our reported provision (benefit) for income taxes and (ii) other discrete tax items. Our structural tax rate for purposes of the calculation of Adjusted EPS for both the three and nine months ended September 30,March 31, 2023 and 2022 was 15.2% and 2021 was 16.5%. The Tax impact of reconciling items and discrete tax items is calculated using the current quarter's estimate of the annual structural tax rate for the full year. This may result in the current period adjustment plus prior period reported quarterly adjustments not summing to the full year adjustment.18.6%, respectively.

FFO (NAREIT) AND FFO (NORMALIZED)
Funds from operations ("FFO") is defined by the National Association of Real Estate Investment Trusts ("Nareit") as net income (loss) excluding depreciation on real estate assets, losses and gains on sale of real estate, net of tax, and amortization of data center leased-based intangibles and("FFO (Nareit)"). We calculate our FFO measures, including FFO (Nareit), adjusting for our share of reconciling items from our unconsolidated joint ventures from FFO ("FFO (Nareit)").ventures. FFO (Nareit) does not give effect to real estate depreciation because these amounts are computed, under GAAP, to allocate the cost of a property over its useful life. Because values for well-maintained real estate assets have historically increased or decreased based upon prevailing market conditions, we believe that FFO (Nareit) provides investors with a clearer view of our operating performance. Our most directly comparable GAAP measure to FFO (Nareit) is net income (loss).
Although Nareit has published a definition of FFO, weWe modify FFO (Nareit), as is common among REITs seeking to provide financial measures that most meaningfully reflect their particular business ("FFO (Normalized)"). Our definition of FFO (Normalized) excludes certain items included in FFO (Nareit) that we believe are not indicative of our core operating results, specifically:
EXCLUDED
Acquisition and Integration Costs
Restructuring chargesand other transformation
Loss (gain) on disposal/write-down of property, plant and equipment, net (excluding real estate)
Other expense (income) expense,, net

CRITICAL ACCOUNTING ESTIMATES
Our discussion and analysis of our financial condition and results of operations are based upon our Condensed Consolidated Financial Statements, which have been prepared in accordance with GAAP. The preparation of these financial statements requires us to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities at the date of the financial statements and for the period then ended. On an ongoing basis, we evaluate the estimates used. We base our estimates on historical experience, actuarial estimates, current conditions and various other assumptions that we believe to be reasonable under the circumstances. These estimates form the basis for making judgments about the carrying values of assets and liabilities and are not readily apparent from other sources. Actual results may differ from these estimates. Our critical accounting estimates include the following, which are listed in no particular order:
Revenue Recognition
Accounting for Acquisitions
Impairment of Tangible and Intangible Assets
Income Taxes
Further detail regarding our critical accounting estimates can be found in "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" in our CurrentAnnual Report, and the Consolidated Financial Statements and the Notes included therein. We have determined that no material changes concerning our critical accounting estimates have occurred since December 31, 2021. See Note 2.k. to Notes to Consolidated Financial Statements included in our Current Report for information regarding the reassessment of the composition of our reporting units as a result of the realignment of our global managerial structure during the second quarter of 2022.

(1)We recognized net foreign currency transaction gains of $58.5 million and $126.8 million for the three and nine months ended September 30, 2022, respectively. These gains primarily consist of the impact of changes in the exchange rate of the Euro and the British pound sterling against the United States dollar on our intercompany balances with and between certain of our subsidiaries.
(2)On March 24, 2022, as a result of our loss of control, we deconsolidated the businesses included in the acquisition of OSG Records Management (Europe) Limited, excluding Ukraine. We recognized a loss of approximately $105.8 million associated with the deconsolidation to Other expense (income), net in the first quarter of 2022 representing the difference between the net asset value prior to the deconsolidation and the subsequent remeasurement of the retained investment to a fair value of zero. We have concluded that the deconsolidation does not meet the criteria to be reported as discontinued operations in our consolidated financial statements, as it does not represent a strategic shift that will have a major effect on our operations and financial results. The loss was partially offset by a gain recorded in the first quarter of 2022 of approximately $35.8 million associated with the Clutter Transaction (as defined below).

DEBT COVENANTS
The Credit Agreement, our bond indentures and other agreements governing our indebtedness contain certain restrictive financial and operating covenants, including covenants that restrict our ability to complete acquisitions, pay cash dividends, incur indebtedness, make investments, sell assets and take other specified corporate actions. The covenants do not contain a rating trigger. Therefore, a change in our debt rating would not trigger a default under the Credit Agreement, our bond indentures or other agreements governing our indebtedness. The Credit Agreement requires that we satisfy a fixed charge coverage ratio and a net total lease adjusted leverage ratio and a fixed charge coverage ratio on a quarterly basis and our bond indentures require that, among other things, we satisfy a leverage ratio (not lease adjusted) or a fixed charge coverage ratio (not lease adjusted), as a condition to taking actions such as paying dividends and incurring indebtedness.
The Credit Agreement uses earnings before interest, taxes, depreciation and amortization and rent expense ("EBITDAR") based calculations and the bond indentures use earnings before interest, taxes, depreciation and amortization ("EBITDA") based calculations as the primary measures of financial performance for purposes of calculating leverage and fixed charge coverage ratios. The EBITDAR- and EBITDA-based leverage calculations include our consolidated subsidiaries, other than those we have designated as "Unrestricted Subsidiaries" as defined in the Credit Agreement and bond indentures. Generally, the Credit Agreement and the bond indentures use a trailing four fiscal quarter basis for purposes of the relevant calculations and require certain adjustments and exclusions for purposes of those calculations, which make the calculation of financial performance for purposes of those calculations under the Credit Agreement and bond indentures not directly comparable to Adjusted EBITDA as presented herein. These adjustments can be significant. For example, the calculation of financial performance under the Credit Agreement and certain of our bond indentures includes (subject to specified exceptions and caps) adjustments for non-cash charges and for expected benefits associated with (i) completed acquisitions, (ii) certain executed lease agreements associated with our data center business that have yet to commence, and (iii) restructuring and other strategic initiatives, such as Project Summit and Project Matterhorn.initiatives. The calculation of financial performance under our other bond indentures includes, for example, adjustments for non-cash charges and for expected benefits associated with (i) completed acquisitions and (ii) events that are extraordinary, unusual or non-recurring.
Our leverage and fixed charge coverage ratios under the Credit Agreement as of September 30, 2022March 31, 2023 are as follows:
 SEPTEMBER 30, 2022MARCH 31, 2023MAXIMUM/MINIMUM ALLOWABLE
Net total lease adjusted leverage ratio5.25.1 Maximum allowable of 7.0
Fixed charge coverage ratio2.52.4 Minimum allowable of 1.5
We are in compliance with our leverage and fixed charge coverage ratios under the Credit Agreement, our bond indentures and other agreements governing our indebtedness as of September 30, 2022.March 31, 2023. Noncompliance with these leverage and fixed charge coverage ratios would have a material adverse effect on our financial condition and liquidity.
Our ability to pay interest on or to refinance our indebtedness depends on our future performance, working capital levels and capital structure, which are subject to general economic, financial, competitive, legislative, regulatory and other factors which may be beyond our control. There can be no assurance that we will generate sufficient cash flow from our operations or that future financings will be available on acceptable terms or in amounts sufficient to enable us to service or refinance our indebtedness or to make necessary capital expenditures.

These rules refer to the controls and other procedures of a company that are designed to ensure that information is recorded, processed, accumulated, summarized, communicated and reported to management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding what is required to be disclosed by a company in the reports that it files under the Exchange Act. As of September 30, 2022March 31, 2023 (the "Evaluation Date"), we carried out an evaluation, under the supervision and with the participation of our management, including our chief executive officer and chief financial officer, of the effectiveness of our disclosure controls and procedures. Based upon that evaluation, our chief executive officer and chief financial officer concluded that, as of the Evaluation Date, our disclosure controls and procedures are effective.
CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING
Our management, with the participation of our principal executive officer and principal financial officer, is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act. Our internal control system is designed to provide reasonable assurance to our management and board of directors regarding the preparation and fair presentation of published financial statements.
ThereDuring the three months ended March 31, 2023, we implemented a new version of our Enterprise Resource Planning system in certain markets as a part of an ongoing system upgrade. We took the necessary steps to monitor and maintain appropriate internal control over financial reporting during this upgrade. We also conducted evaluations prior to and after the implementation of the new system, and confirmed that our internal control over financial reporting remains effective.
Except as described above, there were no changes in our internal control over financial reporting that occurred during the quarter ended September 30, 2022,March 31, 2023, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
