Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIESA. CASH AND CASH EQUIVALENTSCash and cash equivalents include cash on hand and cash invested in highly liquid short-term securities, which have remaining maturities at the date of purchase of less than 90 days. Cash and cash equivalents are carried at cost, which approximates fair value B. ACCOUNTS RECEIVABLE We maintain an allowance for doubtful accounts and a credit memo reserve for estimated losses resulting from the potential inability of our customers to make required payments and potential disputes regarding billing and service issues. The rollforward of the allowance for doubtful accounts and credit memo reserves for the six months ended June 30, 2022 is as follows: Balance as of December 31, 2021 $ 62,009 Credit memos charged to revenue 26,091 Allowance for bad debts charged to expense 9,010 Deductions and other (1) (41,395) Balance as of June 30, 2022 $ 55,715 (1) Primarily consists of the issuance of credit memos, the write-off of accounts receivable, allowances associated with businesses acquired and the impact associated with currency translation adjustments. C. INVENTORY Inventories are stated at the lower of cost or net realizable value, based on a first-in, first-out methodology. Our inventory primarily consists of information technology-related assets including memory, central processing units, hard drives, adaptors and networking. All of our inventory is considered finished goods. Inventory is included as a component of Prepaid expenses and other in our Condensed Consolidated Balance Sheets. At June 30, 2022, we have inventory of approximately $22,400, net of related reserves for obsolete, excess and slow-moving inventory, which was acquired as part of the ITRenew Transaction (as defined in Note 3).

GOODWILL Our reporting units as of December 31, 2021 are described in detail in Note 2.k. to Notes to Consolidated Financial Statements included in our Annual Report. During the second quarter of 2022, as a result of the realignment of our global managerial structure, we reassessed the composition of our reportable segments (see Note 9 for a description and definition of our reportable segments) as well as our reporting units. We note the following changes to our reporting units as a result of the reassessment described above: • our former Europe RIM reporting unit is now managed as two separate reporting units: (1) our Middle East, North Africa and Turkey ("MENAT") businesses will comprise our "MENAT RIM" reporting unit and (2) our other businesses in Europe and South Africa ("ESA") will comprise our “ESA RIM” reporting unit; • our former ANZ RIM and Asia RIM reporting units are now managed as one "APAC RIM" reporting unit; and • our asset lifecycle management ("ALM") business, which includes our legacy secure IT asset disposition business (which was primarily previously included in our North America RIM reporting unit) and the business acquired through our acquisition of Intercept Parent, Inc. ("ITRenew"), will comprise our newly formed "ALM" reporting unit. There were no changes to our Latin America RIM, Global Data Center and Fine Arts reporting units. We have reassigned goodwill associated with the reporting units impacted by the reorganization on a relative fair value basis, where appropriate. The fair value of each of our new reporting units was determined based on the application of a combined weighted average approach of preliminary fair value multiples of revenue and earnings and discounted cash flow techniques. These fair values represent our best estimate and preliminary assessment of goodwill allocations to each of the new reporting units on a relative fair value basis. We have completed an interim goodwill impairment analysis before and after the reporting unit changes, and we have concluded that the goodwill associated with each of our reporting units was not impaired. The goodwill associated with acquisitions completed during the six months of 2022 (as described in Note 3) has been incorporated into our current reporting units. The changes in the carrying value of goodwill attributable to each reportable segment for the six months ended June 30, 2022 are as follows: GLOBAL RIM BUSINESS GLOBAL DATA CENTER BUSINESS CORPORATE AND OTHER BUSINESS TOTAL CONSOLIDATED Goodwill balance, net of accumulated amortization as of December 31, 2021 $ 3,976,261 $ 426,074 $ 61,196 $ 4,463,531 Non-tax deductible goodwill acquired during the period 696 — 581,195 581,891 Goodwill reallocation due to the change in reportable segments (1) (3,409) — 3,409 — Fair value and other adjustments (2) (12,247) — 384 (11,863) Currency effects (97,746) (10,569) (1,553) (109,868) Goodwill balance, net of accumulated amortization as of June 30, 2022 $ 3,863,555 $ 415,505 $ 644,631 $ 4,923,691 Accumulated goodwill impairment balance as of June 30, 2022 $ 132,409 $ — $ 26,011 $ 158,420 (1) For additional information regarding the changes that were made to our reportable segments in the second quarter of 2022, see Note 9. (2) This amount represents an adjustment to goodwill as a result of the deconsolidation of certain businesses, as described in Note 2.l. F. FAIR VALUE MEASUREMENTS The assets and liabilities carried at fair value measured on a recurring basis as of June 30, 2022 and December 31, 2021 are as follows: FAIR VALUE MEASUREMENTS AT JUNE 30, 2022 USING DESCRIPTION TOTAL CARRYING QUOTED PRICES IN SIGNIFICANT OTHER SIGNIFICANT Money Market Funds $ 7,164 $ — $ 7,164 $ — Time Deposits 1,397 — 1,397 — Trading Securities 10,597 10,531 66 — Derivative Assets 53,654 — 53,654 — Deferred Purchase Obligation (as defined in Note 3) 275,100 — — 275,100 FAIR VALUE MEASUREMENTS AT DECEMBER 31, 2021 USING DESCRIPTION TOTAL CARRYING QUOTED PRICES IN SIGNIFICANT OTHER SIGNIFICANT Money Market Funds $ 101,022 $ — $ 101,022 $ — Time Deposits 2,238 — 2,238 — Trading Securities 11,147 11,062 85 — Derivative Assets 11,021 — 11,021 — Derivative Liabilities 8,344 — 8,344 — There were no material items that are measured at fair value on a non-recurring basis at June 30, 2022 and December 31, 2021, other than (i) those disclosed in Note 2.o. to Notes to Consolidated Financial Statements included in our Annual Report, (ii) assets acquired and liabilities assumed through the ITRenew Transaction (as defined and described in Note 3), (iii) our investment in the Clutter JV (as defined in Note 4), and (iv) the fair value of our retained investment of our deconsolidated businesses (as described in Note 2.l.), all of which are based on Level 3 inputs. The fair value of the Deferred Purchase Obligation associated with the ITRenew Transaction was determined utilizing a Monte-Carlo model and takes into account our forecasted projections as it relates to the underlying performance of the business. There were no significant changes to the inputs to the model as of June 30, 2022. G.

STOCK-BASED COMPENSATION Our stock-based compensation expense includes the cost of stock options, restricted stock units ("RSUs"), performance units ("PUs") and shares of stock issued under our employee stock purchase plan ("ESPP") (together, the "Employee Stock-Based Awards"). 2022 RETIREMENT ELIGIBLE CRITERIA For our Employee Stock-Based Awards made on or after March 1, 2022, we have included the following retirement provision: • Upon an award recipient's retirement on or after attaining age 55 with at least five years of service, if the sum of (i) the award recipient’s age at retirement and (ii) the award recipient’s years of service with us totals at least 65, the award recipient is entitled to continued vesting of any outstanding Employee Stock-Based Awards, provided that their retirement occurs on or after a minimum of six months from the grant date (the "Retirement Criteria"). • Accordingly, (i) grants of Employee Stock-Based Awards to an employee who has met the Retirement Criteria on or before the date of grant, or will meet the Retirement Criteria before the six month anniversary in the year of the grant, will be expensed over six months from the date of grant and (ii) grants of Employee Stock-Based Awards to employees who will meet the Retirement Criteria during the award’s normal vesting period will be expensed between the date of grant and the date upon which the award recipient meets the Retirement Criteria. • Stock options and RSUs granted to award recipients who meet the Retirement Criteria will be delivered to the award recipient based upon the original vesting schedule. If an award recipient retires and has met the Retirement Criteria, stock options will remain exercisable until the original expiration date of the stock options. PUs granted to award recipients who meet the Retirement Criteria will be delivered in accordance with the original vesting schedule of the applicable PU award and remain subject to the same performance conditions.

ACQUISITION AND INTEGRATION COSTS Acquisition and integration costs represent operating expenditures directly associated with the closing and integration activities of our business acquisitions that have closed, or are highly probable of closing, and include (i) advisory, legal and professional fees to complete business acquisitions and (ii) costs to integrate acquired businesses into our existing operations, including move, severance, facility upgrade and system integration costs (collectively, "Acquisition and Integration Costs"). Acquisition and Integration Costs do not include costs associated with the formation of joint ventures or costs associated with the acquisition of customer relationships. Total Acquisition and Integration Costs is $16,878 and $32,539 for the three and six months ended June 30, 2022, respectively, and $2,277 for both the three and six months ended June 30, 2021. K. (GAIN) LOSS ON DISPOSAL/WRITE-DOWN OF PROPERTY, PLANT AND EQUIPMENT, NET Consolidated (gain) loss on disposal/write-down of property, plant and equipment, net for the three and six months ended June 30, 2022 and 2021 is as follows: THREE MONTHS ENDED JUNE 30, SIX MONTHS ENDED JUNE 30, 2022 (1) 2021 (2) 2022 (1) 2021 (2) (Gain) Loss on disposal/write-down of property, plant and equipment, net $ (51,249) $ (128,935) $ (51,954) $ (133,386) (1) The gains for the three and six months ended June 30, 2022 primarily consisted of gains of approximately $49,000 associated with the sale and sale-leaseback transactions of 11 facilities and parcels of land in the United States, as part of our program to monetize a portion of our industrial assets. The terms for these leases are consistent with the terms of our lease portfolio, which are disclosed in detail in Note 2.i. to Notes to Consolidated Financial Statements included in our Annual Report. (2) The gains for the three and six months ended June 30, 2021 primarily consisted of gains of approximately $127,400 associated with the sale-leaseback transactions of five facilities in the United Kingdom, as part of our program to monetize a small portion of our industrial assets. The terms for these leases are consistent with the terms of our lease portfolio, which are disclosed in detail in Note 2.i. to Notes to Consolidated Financial Statements included in our Annual Report. L. OTHER (INCOME) EXPENSE, NET Consolidated other (income) expense, net for the three and six months ended June 30, 2022 and 2021 consists of the following: THREE MONTHS ENDED JUNE 30, SIX MONTHS ENDED JUNE 30, DESCRIPTION 2022 2021 2022 2021 Foreign currency transaction (gains) losses, net (1) $ (55,039) $ 4,729 $ (68,240) $ 7,043 Debt extinguishment expense — — 671 — Other, net (2)(3) 13,822 (190,959) 82,253 (188,560) Other (Income) Expense, Net $ (41,217) $ (186,230) $ 14,684 $ (181,517) (1) We recognized net foreign currency transaction gains of $55,039 and $68,240 for the three and six months ended June 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 $105,800 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 subsequent remeasurement of the retained investment to 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 $35,800 associated with the Clutter Transaction (as defined in Note 4). (3) Other, net for the three and six months ended June 30, 2021 is primarily comprised of (a) a gain of approximately $181,200 associated with our IPM Divestment (as defined and discussed in Note 4 to Notes to Consolidated Financial Statements included in our Annual Report) and (b) a gain of approximately $20,300 associated with the loss of control and related deconsolidation, as of May 18, 2021 of one of our wholly owned Netherlands subsidiaries, for which we had value-added tax liability exposure that was recorded in 2019. M. INCOME TAXES We provide for income taxes during interim periods based on our estimate of the effective tax rate for the year. Our effective tax rates for the three and six months ended June 30, 2022 and 2021 are as follows: THREE MONTHS ENDED JUNE 30, SIX MONTHS ENDED JUNE 30, 2022 (1) 2021 (2) 2022 (1) 2021 (2) Effective Tax Rate 8.2 % 28.5 % 10.4 % 27.9 % (1) The primary reconciling items between the federal statutory tax rate of 21.0% and our overall effective tax rate for the three and six months ended June 30, 2022 were the benefits derived from the dividends paid deduction and the differences in the tax rates to which our foreign earnings are subject. In addition, there were gains and losses recorded in Other expense (income), net and Gain (loss) on disposal/write-down of property, plant and equipment net, during the period for which there was an insignificant tax impact. During the first quarter of 2022, there was also a release of valuation allowances on deferred tax assets of our U.S. taxable REIT subsidiaries ("TRS") of approximately $9,900 as a result of the ITRenew Transaction. (2) The primary reconciling items between the federal statutory tax rate of 21.0% and our overall effective tax rate for the three and six months ended June 30, 2021 were the impacts of differences in the tax rates at which our foreign earnings are subject and a discrete tax expense of approximately $12,000 primarily resulting from a tax law change in the United Kingdom, partially offset by the benefits derived from the dividends paid deduction. N. INCOME (LOSS) PER SHARE—BASIC AND DILUTED The calculation of basic and diluted income (loss) per share for the three and six months ended June 30, 2022 and 2021 are as follows: THREE MONTHS ENDED JUNE 30, SIX MONTHS ENDED JUNE 30, 2022 2021 2022 2021 Net Income (Loss) $ 201,858 $ 276,522 $ 243,565 $ 323,153 Less: Net Income (Loss) Attributable to Noncontrolling Interests 1,777 1,237 1,185 2,265 Net Income (Loss) Attributable to Iron Mountain Incorporated (utilized in numerator of Earnings Per Share calculation) $ 200,081 $ 275,285 $ 242,380 $ 320,888 Weighted-average shares—basic 290,756,000 289,247,000 290,542,000 289,001,000 Effect of dilutive potential stock options 1,249,262 641,888 1,122,444 349,163 Effect of dilutive potential RSUs and PUs 481,972 1,190,357 501,975 953,104 Weighted-average shares—diluted 292,487,234 291,079,245 292,166,419 290,303,267 Net Income (Loss) Per Share Attributable to Iron Mountain Incorporated: Basic $ 0.69 $ 0.95 $ 0.83 $ 1.11 Diluted $ 0.68 $ 0.95 $ 0.83 $ 1.11 Antidilutive stock options, RSUs and PUs, excluded from the calculation 234,085 381,900 494,833 2,544,984

Acquisitions

Acquisitions	6 Months Ended

Business Combination and Asset Acquisition [Abstract]
Acquisitions	On January 25, 2022, in order to expand our ALM operations, we acquired an approximately 80% interest in 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 current 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 June 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 expense (income), 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. PRO FORMA FINANCIAL INFORMATION The unaudited consolidated pro forma financial information (the "Pro Forma Financial Information") below summarizes the combined results of Iron Mountain and ITRenew on a pro forma basis as if the ITRenew Transaction had occurred on January 1, 2021. The Pro Forma Financial Information is presented for informational purposes and is not necessarily indicative of the results of operations that would have been achieved if the acquisition had taken place on January 1, 2021. The Pro Forma Financial Information, for the periods presented, includes purchase accounting adjustments (including amortization of acquired customer and supplier intangible assets and depreciation of acquired property, plant and equipment) and related tax effects. Through June 30, 2022, we and ITRenew collectively incurred $59,370 of operating expenditures to complete the ITRenew Transaction (including advisory and professional fees required to complete the ITRenew Transaction). These operating expenditures have been reflected within the results of operations in the Pro Forma Financial Information as if they were incurred on January 1, 2021. THREE MONTHS ENDED JUNE 30, SIX MONTHS ENDED JUNE 30, 2022 2021 2022 2021 Total Revenues $ 1,289,534 $ 1,239,034 $ 2,555,554 $ 2,441,010 Income from Continuing Operations $ 201,858 $ 275,988 $ 243,696 $ 270,605 In addition to our acquisition of ITRenew, we completed one additional acquisition during the first six months of 2022. The Pro Forma Financial Information does not reflect this acquisition due to the insignificant impact of the acquisition on our consolidated results of operations. PRELIMINARY PURCHASE PRICE ALLOCATION A summary of the cumulative consideration paid and the preliminary allocation of the purchase price paid for all of our 2022 acquisitions through June 30, 2022 is as follows: SIX MONTHS ENDED JUNE 30, 2022 Cash Paid (gross of cash acquired) (1) $ 749,596 Deferred Purchase Obligation and Other (2) 276,017 Total Consideration 1,025,613 Fair Value of Identifiable Assets Acquired and Liabilities Assumed: Cash 30,720 Accounts Receivable, Prepaid Expenses and Other Assets 71,838 Property, Plant and Equipment 7,600 Customer and Supplier Relationship Intangible Assets (3) 488,080 Other Intangible Assets (3) 47,300 Operating Lease Right-of-Use Assets 30,395 Accounts Payable, Accrued Expenses and Other Liabilities (60,256) Operating Lease Liabilities (30,395) Deferred Income Taxes (141,560) Total Fair Value of Identifiable Net Assets Acquired 443,722 Goodwill Initially Recorded (4) $ 581,891 (1) Cash paid for acquisitions, net of cash acquired in our Condensed Consolidated Statement of Cash Flows includes contingent and other payments received of $219 for the six months ended June 30, 2022 related to acquisitions made in the years prior to 2022. (2) At June 30, 2022, we included approximately $275,100 in Other long-term liabilities related to the fair value estimate of the Deferred Purchase Obligation for the Remaining Interests. Deferred Purchase Obligation and Other also includes $917 of purchase price associated with the acquisition of a records and information management business completed in 2022. (3) The preliminary weighted average life of the intangible assets acquired in the ITRenew Transaction is approximately 11 years. Intangible assets are included as a component of Other assets, net in our Condensed Consolidated Balance Sheets. (4) Goodwill is primarily attributable to the assembled workforce, expanded market opportunities and costs and other operating synergies anticipated upon the integration of the operations of us and the acquired businesses. The preliminary purchase price allocations that are not finalized as of June 30, 2022 relate to the final assessment of the fair values of intangible assets (primarily customer and supplier relationship intangible assets) and property, plant and equipment associated with the acquisitions we closed in 2022. Any adjustments to our estimates of purchase price allocation will be made in the periods in which the adjustments are determined, but no later than the one year measurement period, and the cumulative effect of such adjustments will be calculated as if the adjustments had been completed as of the acquisition dates. Adjustments recorded during the six months ended June 30, 2022 were not material to our results from operations.

Investments, All Other Investments [Abstract]
Investments	In February 2022, the joint venture formed by MakeSpace Labs, Inc. and us (the "MakeSpace JV") entered into an agreement with Clutter, Inc. ("Clutter") pursuant to which the equityholders of the MakeSpace JV contributed their ownership interests in the MakeSpace JV and Clutter’s shareholders contributed their ownership interests in Clutter to create a newly formed venture (the "Clutter JV"). In exchange for our 49.99% interest in the MakeSpace JV, we received an approximate 27% interest in the Clutter JV (the "Clutter Transaction").

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES Derivative instruments we are party to include: (i) interest rate swap agreements (which are designated as cash flow hedges) and (ii) cross-currency swap agreements (which are designated as net investment hedges). INTEREST RATE SWAP AGREEMENTS DESIGNATED AS CASH FLOW HEDGES In March 2018, we entered into interest rate swap agreements to limit our exposure to changes in interest rates on a portion of our floating rate indebtedness. These swap agreements expired in March 2022. In July 2019, we entered into forward-starting interest rate swap agreements to limit our exposure to changes in interest rates on a portion of our floating rate indebtedness. As of June 30, 2022, we had $350,000 in notional value of interest rate swap agreements outstanding, which expire in March 2024. Under the interest rate swap agreements, we receive variable rate interest payments associated with the notional amount of each interest rate swap, based upon one-month LIBOR, in exchange for the payment of fixed interest rates as specified in the interest rate swap agreements. We have designated these interest rate swap agreements as cash flow hedges. Unrealized gains are recognized as assets, while unrealized losses are recognized as liabilities. CROSS-CURRENCY SWAP AGREEMENTS DESIGNATED AS A HEDGE OF NET INVESTMENT In August 2019, we entered into cross-currency swap agreements to hedge the variability of exchange rate impacts between the United States dollar and the Euro. Under the terms of the cross-currency swap agreements, we notionally exchanged approximately $110,000 at an interest rate of 6.0% for approximately 99,055 Euros at a weighted average interest rate of approximately 3.65%. These cross-currency swap agreements expire in August 2023 ("August 2023 Cross-Currency Swap Agreements"). In September 2020, we entered into cross-currency swap agreements to hedge the variability of exchange rate impacts between the United States dollar and the Euro. Under the terms of the cross-currency swap agreements, we notionally exchanged approximately $359,200 at an interest rate of 4.5% for 300,000 Euros at a weighted average interest rate of approximately 3.4%. These cross-currency swap agreements were set to expire in February 2026. In May 2022, these cross-currency swaps were amended ("February 2026 Cross-Currency Swap Agreements"). Under the terms of the February 2026 Cross-Currency Swap Agreements, we notionally exchanged approximately $359,200 at an interest rate of 4.5% for approximately 340,500 Euros at a weighted average interest rate of approximately 1.2%. These February 2026 Cross-Currency Swap Agreements are set to expire in February 2026. We have designated these cross-currency swap agreements as a hedge of net investment against certain of our Euro denominated subsidiaries and they require an exchange of the notional amounts at maturity. These cross-currency swap agreements are marked to market at each reporting period, representing the fair values of the cross-currency swap agreements, and any changes in fair value are recognized as a component of Accumulated other comprehensive items, net. Unrealized gains are recognized as assets while unrealized losses are recognized as liabilities.

CREDIT AGREEMENT Our credit agreement (the "Credit Agreement") consists of a revolving credit facility (the "Revolving Credit Facility"), a term loan A (the "Term Loan A") and a term loan B (the "Term Loan B"). On March 18, 2022, we entered into an amendment to the Credit Agreement, which included the following changes: (i) extended the maturity date of the Revolving Credit Facility and Term Loan A from June 3, 2023 to March 18, 2027; (ii) refinanced and increased the borrowing capacity that IMI and certain of its United States and foreign subsidiaries are able to borrow under the Revolving Credit Facility from $1,750,000 to $2,250,000; (iii) refinanced the existing Term Loan A with a new $250,000 Term Loan A; and (iv) increased the net total lease adjusted leverage ratio maximum allowable from 6.5x to 7.0x and removed the net secured lease adjusted leverage ratio requirement.

As of June 30, 2022, we had $578,000, $246,875 and $670,250 of outstanding borrowings under the Revolving Credit Facility, Term Loan A and Term Loan B, respectively. In addition, we also had various outstanding letters of credit totaling $3,831. The remaining amount available for borrowing under the Revolving Credit Facility as of June 30, 2022 was $1,668,169 (which represents the maximum availability as of such date). Additionally, the Credit Agreement permits us to incur incremental indebtedness thereunder by adding new term loans or revolving loans or by increasing the principal amount of any existing loans thereunder, subject to a cap contained therein.

All other terms of the AUD Term Loan remain consistent with what was disclosed in Note 7 to Notes to Consolidated Financial Statements included in our Annual Report. The interest rate in effect under the AUD Term Loan was 5.5% and 4.0% as of June 30, 2022 and December 31, 2021, respectively. OUTSTANDING BORROWINGS AU$303,965 INTEREST RATE 5.5% As of June 30, 2022 ACCOUNTS RECEIVABLE SECURITIZATION PROGRAM On June 29, 2022, we amended the Accounts Receivable Securitization Program to (i) increase the maximum borrowing capacity from $300,000 to $325,000, with an option to increase the borrowing capacity to $400,000, (ii) change the interest rate under Accounts Receivable Securitization Program from LIBOR plus 1.0% to SOFR plus 0.95%, with a credit spread adjustment of 0.10% and (iii) extend the maturity date from July 1, 2023 to July 1, 2025, at which point all obligations become due.

MAXIMUM AMOUNT $325,000 OUTSTANDING BORROWING $313,200 INTEREST RATE 2.6% As of June 30, 2022 CASH POOLING We currently utilize four separate cash pooling arrangements. We utilize two separate cash pooling arrangements with Bank Mendes Gans ("BMG"), one of which we utilize to manage global liquidity requirements for our qualified REIT subsidiaries ("QRS") (the "BMG QRS Cash Pool") and the other for our TRSs (the "BMG TRS Cash Pool"). We utilize two separate cash pooling arrangements with JP Morgan Chase Bank, N.A. ("JPM"), one of which we utilize to manage global liquidity requirements for our QRSs in the Asia Pacific region (the "JPM QRS Cash Pool") and the other for our TRSs in the Asia Pacific region (the "JPM TRS Cash Pool") (collectively, the "JPM Cash Pools"). The approximate amount of the net cash position for our cash pools and the approximate amount of the gross position and outstanding debit balances for each of these pools as of June 30, 2022 and December 31, 2021 are as follows: JUNE 30, 2022 DECEMBER 31, 2021 GROSS CASH POSITION OUTSTANDING DEBIT BALANCES NET CASH POSITION GROSS CASH POSITION OUTSTANDING DEBIT BALANCES NET CASH POSITION BMG QRS Cash Pool $ 586,400 $ (583,200) $ 3,200 $ 552,900 $ (552,100) $ 800 BMG TRS Cash Pool 542,700 (541,300) 1,400 606,000 (603,900) 2,100 JPM QRS Cash Pool 17,100 (16,900) 200 9,400 (9,200) 200 JPM TRS Cash Pool 20,800 (20,000) 800 12,000 (9,900) 2,100 The net cash position balances as of June 30, 2022 and December 31, 2021 are reflected as cash and cash equivalents in our Condensed Consolidated Balance Sheets. LETTERS OF CREDIT As of June 30, 2022, we had outstanding letters of credit totaling $37,272, of which $3,831 reduce our borrowing capacity under the Revolving Credit Facility (as described above). The letters of credit expire at various dates between September 2022 and January 2033. 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 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.

Commitments and Contingencies	COMMITMENT 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 $23,000 over the next several years, of which certain amounts would be covered by insurance or indemnity arrangement.

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 $35,800 associated with the Clutter Transaction (as defined in Note 4).

In addition, there were gains and losses recorded in Other expense (income), net and Gain (loss) on disposal/write-down of property, plant and equipment net, during the period for which there was an insignificant tax impact. During the first quarter of 2022, there was also a release of valuation allowances on deferred tax assets of our U.S. taxable REIT subsidiaries ("TRS") of approximately $9,900 as a result of the ITRenew Transaction. (2) The primary reconciling items between the federal statutory tax rate of 21.0% and our overall effective tax rate for the three and six months ended June 30, 2021 were the impacts of differences in the tax rates at which our foreign earnings are subject and a discrete tax expense of approximately $12,000 primarily resulting from a tax law change in the United Kingdom, partially offset by the benefits derived from the dividends paid deduction.
