Summary of Significant Accounting Policies | Summary of Significant Accounting Policies a. Cash, Cash Equivalents and Restricted Cash Cash 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. At March 31, 2020 and December 31, 2019 , we had $6,679 and $4,865 b. Goodwill and Other Intangible Assets and Liabilities Goodwill Our reporting units as of December 31, 2019 are described in detail in Note 2.h. to Notes to Consolidated Financial Statements included in our Annual Report. The goodwill associated with acquisitions completed during the first three months of 2020 (which are described in Note 4) has been incorporated into our reporting units as they existed as of December 31, 2019 . There were no other changes to the composition of our reporting units for the three months ended March 31, 2020 . Since December 31, 2019 , there have been no changes to our accounting polices related to the accounting for goodwill. As of December 31, 2019 , no factors were identified that would alter our October 1, 2019 goodwill impairment analysis. During the first quarter of 2020, we concluded that we had a triggering event related to our Fine Arts reporting unit, requiring us to perform an interim goodwill impairment test. The primary factor contributing to our conclusion was the expected impact of the COVID-19 pandemic to this particular business and its customers and revenue sources, which caused us to believe it was more likely than not that the carrying value of our Fine Arts reporting unit exceeded its fair value. During the first quarter of 2020, we performed an interim goodwill impairment test for our Fine Arts reporting unit utilizing a discounted cash flow model, with updated assumptions on future revenues, operating expenditures and capital expenditures. As a result of the interim goodwill impairment test, we concluded that the fair value of our Fine Arts reporting unit was less than its carrying value and, therefore, we recorded a $23,000 impairment charge on the goodwill associated with this reporting unit during the first quarter of 2020. The remaining goodwill for this reporting unit as of March 31, 2020 is approximately $15,000 . Factors that may impact these assumptions include, but are not limited to: (i) our ability to maintain, or grow, storage rental and service revenues in line with current expectations and (ii) our ability to manage our fixed and variable costs in line with potential future revenue declines. Additionally, we concluded that, as of March 31, 2020, we did not have a triggering event requiring an interim impairment test on the goodwill associated with our other reporting units. However, the duration and severity of the COVID-19 pandemic, as well as the related economic impact on both our business and the businesses of our customers, remain uncertain as of the filing of this Quarterly Report. Any material adverse changes to our businesses that negatively impact their fair values could result in future goodwill impairments. The changes in the carrying value of goodwill attributable to each reportable operating segment for the three months ended March 31, 2020 are as follows: Global RIM Business Global Data Center Business Corporate and Other Business Total Goodwill balance, net of accumulated amortization as of December 31, 2019 $ 3,942,901 $ 424,568 $ 117,740 $ 4,485,209 Non-deductible goodwill acquired during the year 60,018 — — 60,018 Goodwill impairment — — (23,000 ) (23,000 ) Fair value and other adjustments(1) (4,854 ) — 403 (4,451 ) Currency effects (141,752 ) (2,547 ) (974 ) (145,273 ) Goodwill balance, net accumulated amortization as of March 31, 2020 $ 3,856,313 $ 422,021 $ 94,169 $ 4,372,503 Accumulated Goodwill Impairment Balance as of December 31, 2019 $ 132,409 $ — $ 3,011 $ 135,420 Accumulated Goodwill Impairment Balance as of March 31, 2020 $ 132,409 $ — $ 26,011 $ 158,420 ________________________________________________________________ (1) Total fair value and other adjustments include $(4,451) in net adjustments primarily related to customer relationships. Finite-lived Intangible Assets and Liabilities Finite-lived intangible assets and liabilities are primarily comprised of customer relationship intangible assets, customer inducements and data center intangible assets and liabilities. Since December 31, 2019 , there have been no changes to our accounting policies related to the accounting for any of our finite-lived intangible assets and liabilities as disclosed in Note 2.i. to Notes to Consolidated Financial Statements included in our Annual Report. The gross carrying amount and accumulated amortization of our finite-lived intangible assets as of March 31, 2020 and December 31, 2019 are as follows: March 31, 2020 December 31, 2019 Gross Carrying Accumulated Net Carrying Gross Carrying Accumulated Net Carrying Assets: Customer relationship intangible assets $ 1,734,034 $ (544,952 ) $ 1,189,082 $ 1,751,848 $ (544,721 ) $ 1,207,127 Customer inducements 55,571 (30,370 ) 25,201 52,718 (29,397 ) 23,321 Data center lease-based intangible assets(1) 264,631 (114,971 ) 149,660 265,945 (103,210 ) 162,735 Third-party commissions asset(2) 31,708 (5,277 ) 26,431 31,708 (4,134 ) 27,574 $ 2,085,944 $ (695,570 ) $ 1,390,374 $ 2,102,219 $ (681,462 ) $ 1,420,757 Liabilities: Data center below-market leases $ 12,729 $ (4,393 ) $ 8,336 $ 12,750 $ (3,937 ) $ 8,813 _______________________________________________________________ (1) Includes data center in-place lease intangible assets, data center tenant relationship intangible assets and data center above-market in-place lease intangible assets.

Since December 31, 2019, there have been no changes to our accounting policies related to the accounting for our lessor revenue as disclosed in Note 2.l. to Notes to Consolidated Financial Statements included in our Annual Report. Storage rental revenue, including revenue associated with power and connectivity, associated with our Global Data Center Business for the three months ended March 31, 2020 and 2019 are as follows: Three Months Ended March 31, 2020 2019 Storage rental revenue(1) $ 64,595 $ 59,718 ______________________________________________________________ (1) Revenue associated with power and connectivity included within storage rental revenue was $11,413 and $9,118 for the three months ended March 31, 2020 and 2019, respectively. d. Accounts Receivable In June 2016, the Financial Accounting Standards Board ("FASB") issued ASU No. 2016-13, Financial Instruments-Credit Losses-Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). ASU 2016-13 changes how entities will measure credit losses on most financial assets. The standard eliminates the probable initial recognition of estimated losses and provides a forward-looking expected credit loss model for accounts receivable, loans and other financial instruments. Prior to our adoption of ASU 2016-13, we maintained an allowance for doubtful accounts for estimated losses resulting from the potential inability of our customers to make required payments and potential disputes regarding billing and service issues. When calculating the allowance, we considered our past loss experience, current and prior trends in our aged receivables and credit memo activity, current economic conditions, and specific circumstances of individual receivable balances. If the financial condition of our customers were to significantly change, resulting in a significant improvement or impairment of their ability to make payments, an adjustment of the allowance might have been required. Additionally, we write off uncollectible balances as circumstances warrant, generally, no later than one year past due. On January 1, 2020 we adopted ASU 2016-13 on a modified retrospective basis for all financial assets measured at amortized cost. The adoption of ASU 2016-13 did not result in a material impact on our consolidated financial statements. In accordance with the guidance in ASU 2016-13, we now calculate and monitor our allowance considering future potential economic and macroeconomic conditions and reasonable and supportable forecasts for expected future collectability of our outstanding receivables, in addition to the factors identified above. Our considerations when calculating our allowance include, but are not limited to, the following: the location of our businesses, the composition of our customer base, our product and service lines, potential future economic unrest, and potential future macroeconomic factors, including natural disasters and any impacts associated with the COVID-19 pandemic. Continued adjustments will be made should there be any material change to reasonable and supportable forecasts that may impact our likelihood of collection, as it becomes evident, including the effects of the COVID-19 pandemic. Our financial assets measured at amortized cost that potentially subject us to credit risk consist predominantly of our accounts receivable. Our highly diverse global customer base, with no single customer accounting for more than 1% of revenue during the three months ended March 31, 2020 , limits our exposure to concentration of credit risk. However, the COVID-19 pandemic is impacting numerous industries and geographies globally. We continue to monitor the credit worthiness of our customers, customer payment trends and the adequacy of our bad debt allowance as the COVID-19 pandemic continues. The rollforward of allowance for doubtful accounts and credit memo reserves for the three months ended March 31, 2020 is as follows: Allowance for Doubtful Accounts and Credit Memo Reserves Balance at December 31, 2019 $ 42,856 Credit memos charged to revenue 13,030 Allowance for bad debts charged to expense 6,197 Deductions and other(1) (18,062 ) Balance at March 31, 2020 $ 44,021 ______________________________________________________________ (1) Primarily consists of the issuance of credit memos, the write-off of accounts receivable and the impact associated with currency translation adjustments. e. Leases We lease facilities for certain of our warehouses, data centers and office space. We also have land leases, including those on which certain of our facilities are located. Since December 31, 2019 there have been no changes to our accounting policies related to the accounting for leases as disclosed in Note 2.m. to Notes to Consolidated Financial Statements included in our Annual Report. Operating and financing lease right-of-use assets and lease liabilities as of March 31, 2020 and December 31, 2019 are as follows: Description Location in Balance Sheet March 31, 2020 December 31, 2019 Assets: Operating lease right-of-use assets(1) Operating lease right-of-use assets $ 1,906,678 $ 1,869,101 Financing lease right-of-use assets, net of accumulated depreciation(2) Property, Plant and Equipment, Net 316,422 327,215 Total $ 2,223,100 $ 2,196,316 Liabilities: Current Operating lease liabilities Accrued expenses and other current liabilities $ 229,331 $ 223,249 Financing lease liabilities Current portion of long-term debt 44,427 46,582 Total current lease liabilities 273,758 269,831 Long-term Operating lease liabilities Long-term Operating Lease Liabilities, net of current portion 1,760,478 1,728,686 Financing lease liabilities Long-term Debt, net of current portion 312,415 320,600 Total long-term lease liabilities 2,072,893 2,049,286 Total $ 2,346,651 $ 2,319,117 _______________________________________________________________ (1) At March 31, 2020 , these assets are comprised of approximately 99% real estate related assets (which include land, buildings and racking) and 1% non-real estate related assets (which include warehouse equipment, vehicles, furniture and fixtures and computer hardware and software).

In addition, as of March 31, 2020, we do not have any operating or financing leases with related parties that are material to our consolidated financial statements. Other information: Supplemental cash flow information relating to our leases for the three months ended March 31, 2020 and 2019 is as follows: Three Months Ended March 31, Cash paid for amounts included in measurement of lease liabilities: 2020 2019 Operating cash flows used in operating leases $ 86,418 $ 83,676 Operating cash flows used in financing leases (interest) 4,844 6,142 Financing cash flows used in financing leases 12,739 16,675 Non-cash items: Operating lease modifications and reassessments $ 34,916 $ 1,842 New operating leases (including acquisitions) 110,609 21,535 New financing leases, modifications and reassessments 13,061 7,523 f. Stock-Based Compensation We record stock-based compensation expense, utilizing the straight-line method, for the cost of stock options, restricted stock units ("RSUs"), performance units ("PUs") and shares of stock issued under our employee stock purchase plan (together, "Employee Stock-Based Awards"). There have been no significant changes to our accounting policies, assumptions and valuation methodologies related to the accounting for our Employee Stock-Based Awards as disclosed in Note 2.n. to Notes to Consolidated Financial Statements included in our Annual Report. Stock-based compensation expense for Employee Stock-Based Awards for the three months ended March 31, 2020 and 2019 was $6,527 ( $6,065 after tax or $0.02 per basic and diluted share) and $8,519 ( $7,935 after tax or $0.03 per basic and diluted share), respectively. The substantial majority of the stock-based compensation expense for Employee Stock-Based Awards is included in Selling, general and administrative expenses in the accompanying Condensed Consolidated Statements of Operations. As of March 31, 2020 , unrecognized compensation cost related to the unvested portion of our Employee Stock-Based Awards was $73,265 and is expected to be recognized over a weighted-average period of 2.1 years. Stock Options A summary of stock option activity for the three months ended March 31, 2020 is as follows: Stock Options Outstanding at December 31, 2019 4,835,721 Granted 589,993 Exercised (135,312 ) Forfeited (65,861 ) Expired (40,749 ) Outstanding at March 31, 2020 5,183,792 Options exercisable at March 31, 2020 3,786,186 Options expected to vest 1,320,231 Restricted Stock Units The fair value of RSUs vested during the three months ended March 31, 2020 and 2019 is as follows: Three Months Ended March 31, 2020 2019 Fair value of RSUs vested $ 18,379 $ 15,333 A summary of RSU activity for the three months ended March 31, 2020 is as follows: RSUs Non-vested at December 31, 2019 1,203,599 Granted 866,416 Vested (526,086 ) Forfeited (32,661 ) Non-vested at March 31, 2020 1,511,268 RSUs expected to vest 1,480,838 Performance Units The fair value of earned PUs that vested during the three months ended March 31, 2020 and 2019 is as follows: Three Months Ended March 31, 2020 2019 Fair value of earned PUs that vested $ 10,890 $ 6,503 A summary of PU activity for the three months ended March 31, 2020 is as follows: Original PU Adjustment(1) Total Non-vested at December 31, 2019 1,113,691 (314,798 ) 798,893 Granted 425,777 — 425,777 Vested (271,452 ) — (271,452 ) Forfeited/Performance or Market Conditions Not Achieved (36,961 ) (4,710 ) (41,671 ) Non-vested at March 31, 2020 1,231,055 (319,508 ) 911,547 ________________________________________________________________ (1) Represents an increase or decrease in the number of original PUs awarded based on either the final performance criteria or market condition achievement at the end of the performance period of such PUs. As of March 31, 2020 , we expected 100% , 100% and 0% achievement of each of the predefined revenue, return on invested capital and Adjusted EBITDA (as defined in Note 6) targets associated with the awards of PUs made in 2020 , 2019 and 2018 , respectively. g. Income (Loss) Per Share—Basic and Diluted Basic income (loss) per common share is calculated by dividing income (loss) by the weighted average number of common shares outstanding. The calculation of diluted income (loss) per share is consistent with that of basic income (loss) per share but gives effect to all potential common shares (that is, securities such as stock options, RSUs, PUs, warrants or convertible securities) that were outstanding during the period, unless the effect is antidilutive. The calculation of basic and diluted income (loss) per share for the three months ended March 31, 2020 and 2019 are as follows: Three Months Ended March 31, 2020 2019 Income (loss) from continuing operations $ 64,892 $ 30,476 Less: Net income (loss) attributable to noncontrolling interests 917 891 Income (loss) from continuing operations (utilized in numerator of Earnings Per Share calculation) 63,975 29,585 (Loss) income from discontinued operations, net of tax — (24 ) Net income (loss) attributable to Iron Mountain Incorporated $ 63,975 $ 29,561 Weighted-average shares—basic 287,840,000 286,528,000 Effect of dilutive potential stock options 51,799 231,402 Effect of dilutive potential RSUs and PUs 467,334 732,421 Weighted-average shares—diluted 288,359,133 287,491,823 Earnings (losses) per share—basic: Income (loss) from continuing operations $ 0.22 $ 0.10 (Loss) income from discontinued operations, net of tax — — Net income (loss) attributable to Iron Mountain Incorporated(1) $ 0.22 $ 0.10 Earnings (losses) per share—diluted: Income (loss) from continuing operations $ 0.22 $ 0.10 (Loss) income from discontinued operations, net of tax — — Net income (loss) attributable to Iron Mountain Incorporated(1) $ 0.22 $ 0.10 Antidilutive stock options, RSUs and PUs, excluded from the calculation 5,513,714 3,985,161 _______________________________________________________________ (1) Columns may not foot due to rounding. h. Income Taxes We provide for income taxes during interim periods based on our estimate of the effective tax rate for the year. Discrete items and changes in our estimate of the annual effective tax rate are recorded in the period they occur. Our effective tax rate is subject to variability in the future due to, among other items: (1) changes in the mix of income between our qualified REIT subsidiaries ("QRSs") and our domestic taxable REIT subsidiaries ("TRSs"), as well as among the jurisdictions in which we operate; (2) tax law changes; (3) volatility in foreign exchange gains and losses; (4) the timing of the establishment and reversal of tax reserves; and (5) our ability to utilize net operating losses that we generate. Our effective tax rates for the three months ended March 31, 2020 and 2019 were 13.0% and 25.7% , respectively. The primary reconciling items between the federal statutory tax rate of 21.0% and our overall effective tax rate for the three months ended March 31, 2020 and 2019 were the benefits derived from the dividends paid deduction and the impacts of differences in the tax rates at which our foreign earnings are subject, including foreign exchange gains and losses in different jurisdictions with different tax rates. i. Fair Value Measurements Our financial assets or liabilities that are carried at fair value are required to be measured using inputs from the three levels of the fair value hierarchy as disclosed in Note 2.s. to Notes to Consolidated Financial Statements included in our Annual Report. The assets and liabilities carried at fair value measured on a recurring basis as of March 31, 2020 and December 31, 2019 , respectively, are as follows: Fair Value Measurements at Description Total Carrying Quoted prices Significant other Significant Money Market Funds(1) $ 9,194 $ — $ 9,194 $ — Trading Securities 10,131 9,582 (2) 549 (3) — Derivative Assets(4) 5,388 — 5,388 — Derivative Liabilities(4) 23,506 — 23,506 — Fair Value Measurements at Description Total Carrying Value at December 31, 2019 Quoted prices in active markets (Level 1) Significant other observable inputs (Level 2) Significant unobservable inputs (Level 3) Money Market Funds(1) $ 13,653 $ — $ 13,653 $ — Trading Securities 10,732 10,168 (2) 564 (3) — Derivative Liabilities(4) 9,756 — 9,756 — ________________________________________________________________ (1) Money market funds are measured based on quoted prices for similar assets and/or subsequent transactions. (2) These trading securities are measured at fair value using unadjusted quoted market prices in active markets for identical assets that we have the ability to access at the measurement date. (3) These trading securities are measured based on inputs that are observable, other than quoted market prices. (4) Derivative assets and liabilities include (i) interest rate swap agreements, including forward-starting interest rate swap agreements, to limit our exposure to changes in interest rates on a portion of our floating rate indebtedness and (ii) cross-currency swap agreements to hedge the variability of exchange rates impacts between the United States dollar and the Euro and certain of our Euro denominated subsidiaries. Our derivative financial instruments are measured using industry standard valuation models using market-based observable inputs, including interest rate curves, forward and spot prices for currencies and implied volatilities. Credit risk is also factored into the determination of the fair value of our derivative financial instruments. See Note 3 for additional information on our derivative financial instruments. Disclosures are required in the financial statements for items measured at fair value on a non-recurring basis. There were no material items that are measured at fair value on a non-recurring basis at March 31, 2020 and December 31, 2019 , other than (i) those disclosed in Note 2.s. to Notes to Consolidated Financial Statements included in our Annual Report, (ii) those acquired in acquisitions that occurred during the three months ended March 31, 2020 , as described in Note 4, and (iii) the Fine Arts reporting unit, as described in Note 2.b., all of which are based on Level 3 inputs. We account for our investment in the MakeSpace JV (the "MakeSpace Investment") as an equity method investment. The carrying value of the MakeSpace Investment at March 31, 2020 and December 31, 2019 is $14,316 and $18,570 , respectively, and is presented as a component of Other within Other assets, net in our Condensed Consolidated Balance Sheets. The fair value of our long-term debt, which is determined based on either Level 1 inputs or Level 3 inputs, is disclosed in Note 5 and is measured at cost in our Condensed Consolidated Balance Sheets as of March 31, 2020 and December 31, 2019 j.
