Accounting Policies [Abstract]  
Summary of Significant Accounting Policies Summary of Significant Accounting PoliciesThis Note 2 to Notes to Condensed Consolidated Financial Statements provides information and disclosure regarding certain of our significant accounting policies and should be read in conjunction with Note 2 to Notes to Consolidated Financial Statements included in our Annual Report, which may provide additional information with regard to the accounting policies set forth herein and other of our 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 September 30, 2019 and December 31, 2018, we had $8,057 and $15,141, respectively, of restricted cash held by certain financial institutions related to bank guarantees.
b.    Goodwill and Other Intangible Assets and Liabilities
Goodwill
Since December 31, 2018, there have been no changes to our accounting polices related to the accounting for goodwill. As of September 30, 2019 and December 31, 2018, no factors were identified that would alter our October 1, 2018 goodwill impairment analysis.
Our reporting units as of December 31, 2018 are described in detail in Note 2.h. to Notes to Consolidated Financial Statements included in our Annual Report. On March 19, 2019, we divested the business included in our former Consumer Storage reporting unit, which had no goodwill associated with it at December 31, 2018 or at the date of the divestment. See Note 10 for additional information.
The goodwill associated with acquisitions completed during the first nine months of 2019 (which are described in Note 4) has been incorporated into our reporting units as they existed as of December 31, 2018.
The changes in the carrying value of goodwill attributable to each reportable operating segment for the nine months ended September 30, 2019 are as follows:

Data Center Lessor Considerations

Our data center business features storage rental provided to customers at contractually specified rates over a fixed contractual period. Prior to January 1, 2019, our data center revenue contracts were accounted for in accordance with Accounting Standards Codification (“ASC”) No. 840, Leases ("ASC 840"). On January 1, 2019, we adopted ASU 2016-02, as described in more detail in Note 2.d. Beginning on January 1, 2019, our data center revenue contracts are accounted for in accordance with ASU 2016-02. ASU 2016-02 provides a practical expedient which allows lessors to account for nonlease components (such as power and connectivity, in the case of our data center business) with the related lease component if both the timing and pattern of transfer are the same for nonlease components and the lease component, and the lease component would be classified as an operating lease. The single combined component is accounted for under ASU 2016-02 if the lease component is the predominant component and is accounted for under ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU 2014-09"), if the nonlease components are the predominant components. We have elected to take this practical expedient. Storage rental revenue associated with our data center business was approximately $62,000 and $182,300 for the three and nine months ended September 30, 2019, respectively, which includes approximately $12,000 and $31,000 of revenue associated with power and connectivity for the three and nine months ended September 30, 2019, respectively. The revenue related to the service component of our data center business remains unchanged from the adoption of ASU 2016-02 and is recognized in the period the related services are provided. Our accounting treatment for data center revenue was not significantly impacted by the adoption of ASU 2016-02.

The future minimum lease payments we expect to receive under non-cancellable data center operating leases, for which we are the lessor, excluding month to month leases, for the next five years are as follows:

d. Leases

We lease facilities for certain warehouses, data centers and office space. We also have land leases, including those on which certain facilities are located. The majority of our leased facilities are classified as operating leases that, on average, have initial lease terms of five to 10 years, with one or more lease renewal options to extend the lease term. Our lease renewal option terms generally range from one to five years. The exercise of the lease renewal option is at our sole discretion and may contain fixed rent, fair market value based rent or Consumer Price Index rent escalation clauses. We include option periods in the lease term when our failure to renew the lease would result in an economic disincentive, thereby making it reasonably certain that we will renew the lease. We recognize straight line rental expense over the life of the lease and any fair market value or Consumer Price Index rent escalations are recognized as variable lease expense in the period in which the obligation is incurred. In addition, we lease certain vehicles and equipment. Vehicle and equipment leases have lease terms ranging from one to seven years.
In February 2016, the Financial Accounting Standards Board ("FASB") issued ASU 2016-02, Leases (Topic 842), which requires lessees to recognize assets and liabilities on the balance sheet for the rights and obligations created by all leases, both operating and financing (formerly referred to as capital leases under ASC 840). ASU 2016-02 requires certain qualitative and quantitative disclosures designed to give financial statement users information on the amount, timing, and uncertainty of cash flows arising from leases.

We adopted ASU 2016-02 on January 1, 2019 on a modified retrospective basis under which we recognized and measured leases existing at, or entered into after, the beginning of the period of adoption. Therefore, we applied ASC 840 to all earlier comparative periods (prior to the adoption of ASU 2016-02), including disclosures, and recognized the effects of applying ASU 2016-02 as a cumulative-effect adjustment to (Distributions in excess of earnings) Earnings in excess of distributions as of January 1, 2019, the effective date of the standard. As such, the comparative Condensed Consolidated Balance Sheet as of December 31, 2018 has not been restated to reflect the adoption of ASU 2016-02. Accordingly, the majority of the amount presented as deferred rent liabilities on our Consolidated Balance Sheet as of December 31, 2018 is now included in the calculation of operating lease right-of-use assets and any remaining amounts are now classified within other liability line items on our Condensed Consolidated Balance Sheet as of September 30, 2019. The transition guidance associated with ASU 2016-02 also permitted certain practical expedients. We elected the "package of 3" practical expedients permitted under the transition guidance which, among other things, allowed us to carryforward our historical lease classifications. We also adopted an accounting policy which provides that leases with an initial term of 12 months or less will not be included within the lease right-of-use assets and lease liabilities recognized on our Condensed Consolidated Balance Sheets after the adoption of ASU 2016-02. We will continue to recognize the lease payments for those leases with an initial term of 12 months or less in the Condensed Consolidated Statements of Operations on a straight-line basis over the lease term.

The lease right-of-use assets and related lease liabilities are classified as either operating or financing. Lease right-of-use assets are calculated as the net present value of future payments plus any capitalized initial direct costs less any tenant improvements or lease incentives. Lease liabilities are calculated as the net present value of future payments. In calculating the present value of the lease payments, we will utilize the rate stated within the lease (in the limited circumstances when such rate is available) or, if no rate is explicitly stated, we have elected to utilize a rate that reflects our securitized incremental borrowing rate by geography for the lease term. In July 2018, the FASB issued ASU No. 2018-11, Leases - Targeted Improvements ("ASU 2018-11"). ASU 2018-11 provides a practical expedient which allows lessees to account for nonlease components (which include common area maintenance, taxes, and insurance) with the related lease component. Any variable nonlease components are not included within the lease right-of-use asset and lease liability on the Condensed Consolidated Balance Sheets, and instead, are reflected as an expense in the period incurred. We have elected to take this practical expedient upon adoption of ASU 2016-02.

At January 1, 2019, we recognized the cumulative effect of initially applying ASU 2016-02 as an adjustment to the opening balance of (Distributions in excess of earnings) Earnings in excess of distributions, resulting in an increase of approximately $5,800 to stockholders' equity due to certain build to suit leases that were accounted for as financing leases under ASC 840, Leases, but are accounted for as operating leases under ASU 2016-02 at January 1, 2019.
Operating and financing lease right-of-use assets and lease liabilities as of September 30, 2019 and January 1, 2019 (date of adoption of ASU 2016-02) are as follows:

(1)
Estimated minimum future lease payments exclude variable common area maintenance charges, insurance and taxes. Differences in estimated lease payments between September 30, 2019 and December 31, 2018 are primarily related to adjustments to account for certain build to suit leases that were accounted for as financing obligations under ASC 840 but are accounted for as operating leases under ASU 2016-02 and foreign currency exchange rate impacts.
(2)
Includes capital lease and financing obligations associated with build to suit lease transactions at December 31, 2018.

e.    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.
For our Employee Stock-Based Awards made on or after February 20, 2019, we have included the following retirement provision: Upon an employee’s retirement on or after attaining age 58, if the sum of (i) the award recipient’s age at retirement and (ii) the award recipient’s years of service with the company totals at least 70, the award recipient is entitled to continued vesting of any outstanding Employee Stock-Based Awards which include the 2019 Retirement Criteria subsequent to their retirement, provided that, for awards granted in the year of retirement, their retirement occurs on or after July 1st (the “2019 Retirement Criteria”). Accordingly, (i) grants of Employee Stock-Based Awards to an employee who has met the 2019 Retirement Criteria on or before the date of grant, or will meet the Retirement Criteria before July 1st of the year of the grant, will be expensed between the date of grant and July 1st of the grant year and (ii) grants of Employee Stock-Based Awards to employees who will meet the 2019 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 2019 Retirement Criteria. Stock options and RSUs granted to recipients who meet the 2019 Retirement Criteria will continue vesting on the original vesting schedule, and the stock options will remain exercisable up to three years after retirement, or the original expiration date of the stock options, if earlier. PUs granted to recipients who meet the 2019 Retirement Criteria will continue to vest and be delivered in accordance with the original vesting schedule of the applicable PU award and remain subject to the same performance conditions.
Stock-based compensation expense for Employee Stock-Based Awards for the three and nine months ended September 30, 2019 was $7,120 ($6,632 after tax or $0.02 per basic and diluted share) and $28,140 ($26,216 after tax or $0.09 per basic and diluted share), respectively, and for the three and nine months ended September 30, 2018 was $7,279 ($6,734 after tax or $0.02 per basic and diluted share) and $23,352 ($21,599 after tax or $0.08 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 September 30, 2019, unrecognized compensation cost related to the unvested portion of our Employee Stock-Based Awards was $50,152 and is expected to be recognized over a weighted-average period of 1.9 years.

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 September 30, 2019, we expected 100%, 50% and 100% achievement of each of the predefined revenue, return on invested capital and Adjusted EBITDA (as defined in Note 7) targets associated with the awards of PUs made in 2019, 2018 and 2017, respectively.
f.    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 or PUs) that were outstanding during the period, unless the effect is antidilutive.
The calculation of basic and diluted income (loss) per share for the three and nine months ended September 30, 2019 and 2018 are as follows:

g. Income Taxes
We provide for income taxes during interim periods based on our estimate of the effective tax rate for the year. Our estimate of the effective tax rates for the years ending December 31, 2019 and 2018 reflect the impact of the U.S. tax reform legislation, commonly referred to as the Tax Cuts and Jobs Act (the “Tax Reform Legislation”). See Note 7 to Notes to Consolidated Financial Statements included in our Annual Report for additional information regarding the impact the Tax Reform Legislation had on us. 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 and nine months ended September 30, 2019 and 2018 are as follows:
 
Three Months Ended

The primary reconciling items between the federal statutory tax rate of 21.0% and our overall effective tax rate for the three and nine months ended September 30, 2019 and for the three months ended September 30, 2018 were the benefit derived from the dividends paid deduction and the impact 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.  
(2)
The primary reconciling items between the federal statutory tax rate of 21.0% and our overall effective tax rate for the nine months ended September 30, 2018 were the benefit derived from the dividends paid deduction, a discrete tax benefit of approximately $14,000 associated with the resolution of a tax matter and the impact 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.
h. 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. A financial asset or liability's classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.
The three levels of the fair value hierarchy are as follows:
Level 1—Inputs are unadjusted quoted prices in active markets for identical assets or liabilities that we have the ability to access at the measurement date.
Level 2—Inputs include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (i.e., interest rates, yield curves, etc.), and inputs that are derived principally from or corroborated by observable market data by correlation or other means (market corroborated inputs).
Level 3—Unobservable inputs that reflect our assumptions about the assumptions that market participants would use in pricing the asset or liability.
The assets and liabilities carried at fair value measured on a recurring basis as of September 30, 2019 and December 31, 2018, respectively, are as follows:

Certain 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, (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 and (iii) short-term (six months or less) foreign exchange currency forward contracts that we have entered into to hedge certain of our foreign exchange intercompany exposures. 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 September 30, 2019 and December 31, 2018, other than those disclosed in Note 2.s. to Notes to Consolidated Financial Statements included in our Annual Report, those acquired in acquisitions that occurred during the nine months ended September 30, 2019 and our initial investment in Makespace LLC (as disclosed in Note 10), all of which are based on Level 3 inputs.
The fair value of our long-term debt, which was determined based on either Level 1 inputs or Level 3 inputs, is disclosed in Note 5. Long-term debt is measured at cost in our Condensed Consolidated Balance Sheets as of September 30, 2019 and December 31, 2018.

j. Gain on Disposal/Write-Down of Property, Plant and Equipment, Net

Consolidated gain on disposal/write-down of property, plant and equipment, net, for the three and nine months ended September 30, 2019 was approximately $9,300 and $17,100, respectively.

During the second quarter of 2019, we began exploring strategic options regarding how to maintain and support the infrastructure of select offerings within our Iron Mountain Iron Cloud (“Iron Cloud”) portfolio. As a result, during the second quarter of 2019, we performed a long-lived asset impairment analysis on the assets associated with these select offerings and concluded that the associated carrying value of the long-lived assets (which consisted entirely of property, plant and equipment) was not recoverable based upon the underlying cash flows associated with these select offerings. On September 30, 2019, we entered into an agreement (the “Iron Cloud Outsourcing Agreement”) with a wholesale provider of data infrastructure and data management services to outsource the operation, infrastructure management and maintenance and delivery of select offerings within our Iron Cloud portfolio. In conjunction with the entry into the Iron Cloud Outsourcing Agreement, we also sold certain IT infrastructure assets and the rights to certain hardware and software maintenance contracts used to deliver these Iron Cloud offerings. As a result of our long-lived asset impairment analysis and sale of certain IT infrastructure assets and rights to certain hardware and software maintenance contracts, we recognized an impairment charge and a loss on sale of the assets totaling approximately $800 and $24,800 during the three and nine months ended September 30, 2019, respectively.

The gain for the nine months ended September 30, 2019 consisted primarily of gains associated with (i) a sale-leaseback transaction of five facilities in the United States of approximately $9,800 during the third quarter of 2019 and (ii) the sale of certain land and buildings in the United Kingdom of approximately $36,000 during the second quarter of 2019. These gains were partially offset by losses primarily associated with (i) the impairment charge on the assets associated with the select offerings within our Iron Cloud portfolio, as described above, and (ii) the write-down of certain property, plant and equipment in our North American Records and Information Management Business of approximately $3,100.
k.    Other (Income) Expense, Net

The gain or loss on foreign currency transactions, calculated as the difference between the historical exchange rate and the exchange rate at the applicable measurement date, include gains or losses related to (i) borrowings in certain foreign currencies under our Revolving Credit Facility (as defined and discussed more fully in Note 5), (ii) our Euro Notes (as defined in Note 5), (iii) certain foreign currency denominated intercompany obligations of our foreign subsidiaries to us and between our foreign subsidiaries, which are not considered permanently invested, and (iv) amounts that are paid or received on the net settlement amount from forward contracts (as more fully discussed in Note 3).
l.    New Accounting Pronouncements
In August 2018, the FASB issued ASU No. 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (a consensus of the FASB Emerging Issues Task Force) ("ASU 2018-15"). ASU 2018-15 aligns the accounting for costs incurred to implement a cloud computing arrangement that is a service arrangement with the guidance on capitalizing costs associated with developing or obtaining internal-use software. We adopted ASU 2018-15 on January 1, 2019. ASU 2018-15 did not have a material impact on our consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02. We adopted ASU 2016-02 on January 1, 2019 on a modified retrospective basis. See Note 2.d. for information regarding the impact of the adoption of ASU 2016-02 on our consolidated financial statements.
m. Correction in Presentation

Subsequent to our conversion to a REIT, we have historically classified gains on sale of real estate, net of tax, as a separate line on our consolidated statements of operations and excluded such amounts from our reported operating income. We presented such amounts net of tax as these gains were presented below the provision (benefit) for income taxes on our consolidated statements of operations. Commencing with the first quarter of 2019, we now present gains on sale of real estate as a component of operating income in the line item (Gain) loss on disposal/write-down of property, plant and equipment, net. See Note 2.j. for details of the (gain) loss on disposal/write-down of property, plant and equipment, net recognized during the three and nine months ended September 30, 2019. Such amounts are presented gross of tax with any tax impact presented within Provision (benefit) for income taxes. All prior periods will be conformed to this presentation. During the third quarter of 2018, we recognized approximately $1,300 of gains on sale of real estate, net of tax. During the fourth quarter of 2018, we recognized approximately $54,000 of gains on sale of real estate, net of tax.
n. Immaterial Restatement

In June 2019, we received a notification of assessment from tax and customs authorities in the Netherlands related to a value-added tax (“VAT”) liability of approximately 16,800 Euros primarily related to the years ending December 31, 2018 and 2017. We have established a reserve for this matter based upon our estimate of the amount of loss that is both probable and estimable, inclusive of interest and penalties. See Note 8 for additional information on this matter.
This matter relates to periods prior to January 1, 2019, resulting in (i) an understatement of our prior years' reported selling, general and administrative expense and interest expense and (ii) an overstatement of our prior years’ reported provision for income taxes for the related tax impact. Based on our estimate of the amount of loss related to this matter that is both probable and estimable, we believe selling, general and administrative expenses and interest expense were understated by approximately $11,000 and $400, respectively, and the provision for income taxes was overstated by approximately $2,000 for the year ended December 31, 2018, which, in the aggregate, would reduce net income from continuing operations by approximately $9,400 for the year ended December 31, 2018. Based on our estimate of the amount of loss related to this matter that is both probable and estimable, we believe the selling, general and administrative expenses and interest expense were understated by approximately $16,600 and $100, respectively, and the provision for income taxes was overstated by approximately $3,000 for the year ended December 31, 2017, which, in the aggregate, would reduce net income from continuing operations by approximately $13,700 for the year ended December 31, 2017. We have determined that no prior period financial statement was materially misstated as a result of the previously unrecorded reserves related to this matter. As a result, we have restated ending (Distributions in excess of earnings) Earnings in excess of distributions as of December 31, 2018 in the amount of approximately $23,100 for the cumulative impact of the aforementioned items. There was no material impact to the Condensed Consolidated Statement of Operations for the three and nine months ended September 30, 2019, as a result of this matter.
Additionally, we have restated our 2018 Condensed Consolidated Balance Sheet, and each of our Condensed Consolidated Statements of Operations, our Condensed Consolidated Statements of Comprehensive Income (Loss), our Condensed Consolidated Statements of Equity and the related notes for the three and nine months ended September 30, 2018 to reflect the impact of the reserve we have established for this matter in those periods. There was no change to the following lines of the Condensed Consolidated Statement of Cash Flows for the nine months ended September 30, 2018: (1) cash flows from operating activities, (2) cash flows from investing activities and (3) cash flows from financing activities.
