REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the Board of Directors of Iron Mountain Incorporated

OPINION ON THE FINANCIAL STATEMENTS

We have audited the accompanying consolidated balance sheets of Iron Mountain Incorporated and subsidiaries (the “Company”) as of December 31, 2020 and 2019, the related consolidated statements of operations, comprehensive income (loss), equity, and cash flows, for each of the three years in the period ended December 31, 2020, and the related notes and the schedule listed in the Index at Item 15 (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 24, 2021, expressed an unqualified opinion on the Company’s internal control over financial reporting.

BASIS FOR OPINION

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

CRITICAL AUDIT MATTER

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

GOODWILL - GLOBAL DATA CENTER REPORTING UNIT - REFER TO NOTE 2.K. TO THE FINANCIAL STATEMENTS

CRITICAL AUDIT MATTER DESCRIPTION

The Company’s evaluation of goodwill for impairment involves the comparison of the fair value of each reporting unit to its carrying value. The Company determined the fair value of the Global Data Center reporting unit using a combined approach based on the present value of future cash flows (the “Discounted Cash Flow Model”) and market multiples (the “Market Approach”). The determination of the fair value using the Discounted Cash Flow Model requires management to make significant assumptions related to future revenue growth rates, operating margins, discount rates and capital expenditures. The determination of the fair value using the Market Approach requires management to make significant assumptions related to adjusted earnings before interest, taxes, depreciation and amortization (“Adjusted EBITDA”) multiples. Changes in economic and operating conditions impacting these assumptions or changes in multiples could result in goodwill impairments in future periods. The goodwill balance allocated to the Global Data Center reporting unit was $431 million as of October 1, 2020 (goodwill impairment testing date). The fair value of the Global Data Center reporting unit exceeded its carrying value as of the measurement date and, therefore, no impairment was recognized.

The Global Data Center reporting unit’s fair value exceeded its carrying value by less than 10%, accordingly, auditing the assumptions used in the goodwill impairment analysis for this reporting unit involved especially subjective judgment.

HOW THE CRITICAL AUDIT MATTER WAS ADDRESSED IN THE AUDIT

Our audit procedures related to future revenue growth rates, operating margins and capital expenditures (collectively, the “Forecast”), Adjusted EBITDA multiples and the selection of discount rates for the Global Data Center reporting unit included the following, among others:

We tested the effectiveness of controls over the evaluation of goodwill for impairment, including those over the Forecast and the selection of the Adjusted EBITDA multiples and discount rates.
We evaluated management’s ability to accurately forecast by comparing actual results to management’s historical forecasts.
We evaluated the reasonableness of management’s Forecast by comparing it to (1) historical results, (2) internal communications to management and the Board of Directors, and (3) forecasted information included in Company press releases and industry reports of the Company and companies in its peer group.
With the assistance of our fair value specialists, we evaluated the Adjusted EBITDA multiples, including testing the underlying source information and mathematical accuracy of the calculations and comparing the multiples selected by management to its guideline companies.
With the assistance of our fair value specialists, we evaluated the discount rates, including testing the underlying source information and the mathematical accuracy of the calculations, and developing a range of independent estimates and comparing those to the discount rates selected by management.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

DECEMBER 31, 2020

(In thousands, except share and per share data)

1. NATURE OF BUSINESS

In March 2020, the World Health Organization declared a novel strain of coronavirus (“COVID-19”) a pandemic. This resulted in U.S. federal, state and local and foreign governments and private entities mandating various restrictions, including travel restrictions, restrictions on public gatherings and stay-at-home orders and advisories. In response, we temporarily closed certain of our offices and facilities across the world and implemented certain travel restrictions for our employees. The preventative and protective actions that governments have ordered, or we or our customers have implemented, have resulted in a period of reduced service operations and business disruption for us, our customers and other third parties with which we do business. Currently, certain of the restrictions have been lifted; however, other restrictions still remain and the broader impacts of the COVID-19 pandemic on our financial position, results of operations and cash flows, including impacts to the estimates we use in the preparation of our financial statements, remain uncertain and difficult to predict as information continues to evolve, and the severity and duration of the pandemic remains unknown, as is our visibility of its effect on the markets we serve and our customers within those markets.

In October 2019, we announced a global program designed to better position us for future growth and achievement of our strategic objectives (“Project Summit”). See Note 2.k. and Note 12.

On January 10, 2018, we completed the acquisition of IO Data Centers, LLC (“IODC”). See Note 3.

We have been organized and have operated as a real estate investment trust for United States federal income tax purposes (“REIT”) beginning with our taxable year ended December 31, 2014.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

A. PRINCIPLES OF CONSOLIDATION

The accompanying financial statements reflect our financial position, results of operations, comprehensive income (loss), equity and cash flows on a consolidated basis. All intercompany transactions and account balances have been eliminated.

B. USE OF ESTIMATES

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) 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.

C. FOREIGN CURRENCY

Local currencies are the functional currencies for our operations outside the United States, with the exception of certain foreign holding companies, whose functional currency is the United States dollar. In those instances where the local currency is the functional currency, assets and liabilities are translated at period-end exchange rates, and revenues and expenses are translated at average exchange rates for the applicable period. See Note 2.q.

D. 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.

E. ALLOWANCE FOR DOUBTFUL ACCOUNTS AND CREDIT MEMO RESERVES

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.

In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ("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.

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. Under ASU 2016-13, we 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 considering our past loss experience, current and prior trends in our aged receivables and credit memo activity. 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. Our highly diverse global customer base, with no single customer accounting for more than 1% of revenue during the years ended December 31, 2020, 2019 and 2018, limits our exposure to concentration of credit risk. Additionally, we write off uncollectible balances as circumstances warrant, generally, no later than one year past due.

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.

Rollforward of allowance for doubtful accounts and credit memo reserves is as follows:


YEAR ENDED DECEMBER 31,	BALANCE AT BEGINNING OF THE YEAR		CREDIT MEMOS CHARGED TO REVENUE		ALLOWANCE FOR BAD DEBTS CHARGED TO EXPENSE		DEDUCTIONS AND OTHER(1)		BALANCE AT END OF THE YEAR
2020	$	42,856	$	55,118	$	34,411	$	(75,404)	$	56,981
2019	43,584		51,846		19,389		(71,963)		42,856
2018	46,648		36,329		18,625		(58,018)		43,584

F. CONCENTRATIONS OF CREDIT RISK

Financial instruments that potentially subject us to credit risk consist principally of cash and cash equivalents (including money market funds and time deposits) and accounts receivable. The only significant concentrations of liquid investments as of December 31, 2020 and 2019 related to cash and cash equivalents. At December 31, 2020, we had money market funds with four “Triple A” rated money market funds and time deposits with one global bank. At December 31, 2019, we had money market funds with seven “Triple A” rated money market funds. As per our risk management investment policy, we limit exposure to concentration of credit risk by limiting the amount invested in any one mutual fund to a maximum of 1% of the fund's total assets or in any one financial institution to a maximum of $75,000. See Note 2.o.

G. PREPAID EXPENSES AND ACCRUED EXPENSES

There are no prepaid expenses with items greater than 5% of total current assets as of December 31, 2020 and 2019.

Accrued expenses, with items greater than 5% of total current liabilities are shown separately, and consist of the following:

Property, plant and equipment	$	8,246,337	$	8,048,906

Minor maintenance costs are expensed as incurred. Major improvements which extend the life, increase the capacity or improve the safety or the efficiency of property owned are capitalized and depreciated. Major improvements to leased buildings are capitalized as leasehold improvements and depreciated.

We capitalize interest expense during the active construction period of major capital projects. Capitalized interest is added to the cost of the underlying assets and is amortized over the useful lives of the assets. During the years ended December 31, 2020, 2019 and 2018, capitalized interest is as follows:


	YEAR ENDED DECEMBER 31,
	2020		2019		2018
Capitalized interest	$	14,321	$	15,980	$	3,732

We develop various software applications for internal use. Computer software costs associated with internal use software are expensed as incurred until certain capitalization criteria are met. Third party consulting costs, as well as payroll and related costs for employees directly associated with, and devoting time to, the development of internal use computer software projects (to the extent time is spent directly on the project) are capitalized. Capitalization begins when the design stage of the application has been completed and it is probable that the project will be completed and used to perform the function intended. Capitalization ends when the asset is ready for its intended use. Depreciation begins when the software is placed in service. Computer software costs that are capitalized are periodically evaluated for impairment.

During the years ended December 31, 2020, 2019 and 2018, capitalized costs associated with the development of internal use computer software projects are as follows:


	YEAR ENDED DECEMBER 31,
	2020		2019		2018
Capitalized costs associated with the development of internal use computer software projects	$	38,329	$	34,650	$	29,407

Entities are required to record the fair value of a liability for an asset retirement obligation in the period in which it is incurred. Asset retirement obligations represent the costs to replace or remove tangible long-lived assets required by law, regulatory rule or contractual agreement. Our asset retirement obligations are primarily the result of requirements under our facility lease agreements which generally have “return to original condition” clauses which would require us to remove or restore items such as shred pits, vaults, demising walls and office build-outs, among others. The significant assumptions used in estimating our aggregate asset retirement obligations are the timing of removals, the probability of a requirement to perform, estimated cost and associated expected inflation rates that are consistent with historical rates and credit-adjusted risk-free rates that approximate our incremental borrowing rate. Our asset retirement obligations at December 31, 2020 and 2019 were $34,537 and $30,831, respectively.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

I. 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 typically have lease terms ranging from one to seven years.

We account for all leases, both operating and financing, in accordance with ASU No. 2016-02 Leases (Topic 842), as amended ("ASU 2016-02") which we adopted on January 1, 2019 on a modified retrospective basis. 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 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 our 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 utilize the rate stated in the lease (in the limited circumstances when such rate is explicitly stated) or, if no rate is explicitly stated, we utilize a rate that reflects our securitized incremental borrowing rate by geography for the lease term. We 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 our Consolidated Balance Sheets, and instead, are reflected as an expense in the period incurred.

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 Accounting Standards Codification (“ASC”) 840, Leases (“ASC 840”) but are accounted for as operating leases under ASU 2016-02.

Operating and financing lease right-of-use assets and lease liabilities as of December 31, 2020 and 2019 are as follows:


	DECEMBER 31,
DESCRIPTION	2020		2019
Assets:

Financing lease liabilities(3)	323,162		320,600

(1)At December 31, 2020 and 2019, 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).

(2)At December 31, 2020, these assets are comprised of approximately 72% real estate related assets and 28% non-real estate related assets. At December 31, 2019, these assets are comprised of approximately 69% real estate related assets and 31% non-real estate related assets.

(3)Financing lease right-of-use assets, current financing lease liabilities and long-term financing lease liabilities are included within Property, Plant and Equipment, Net, Current portion of long-term debt and Long-term Debt, net of current portion, respectively, within our Consolidated Balance Sheets.

At December 31, 2020, we had seven leases which we have signed but which have not yet commenced and are not included in our lease obligation table above. The total undiscounted minimum lease payments for these leases are approximately $236,200 and have lease terms that range from 10 to 25 years. Each of these leases is expected to commence during 2021, with the exception of one lease where the lease commencement date will be driven by the completion of the building construction, which is expected to occur by the end of 2021 or in early 2022.

J. LONG-LIVED ASSETS

We review long-lived assets, including all finite-lived intangible assets, for impairment whenever events or changes in circumstances indicate the carrying amount of such assets may not be recoverable. Recoverability of these assets is determined by comparing the sum of the forecasted undiscounted net cash flows of the operation to which the assets relate to their carrying amount. The operations are generally distinguished by the business segment and geographic region in which they operate. If it is determined that we are unable to recover the carrying amount of the assets, the long-lived assets are written down, on a pro rata basis, to fair value. Fair value is determined based on discounted cash flows or appraised values, depending upon the nature of the assets. Long-lived assets, including finite-lived intangible assets, are amortized over their useful lives. Annually, or more frequently if events or circumstances warrant, we assess whether a change in the lives over which long-lived assets, including finite-lived intangible assets, are amortized is necessary.

K. GOODWILL AND OTHER INDEFINITE-LIVED INTANGIBLE ASSETS

Goodwill and intangible assets with indefinite lives are not amortized but are reviewed annually for impairment or more frequently if impairment indicators arise. Other than goodwill, we currently have no intangible assets that have indefinite lives and which are not amortized.

We have selected October 1 as our annual goodwill impairment review date. We have performed our annual goodwill impairment review as of October 1, 2020, 2019 and 2018. We concluded that as of October 1, 2020, 2019 and 2018, goodwill was not impaired. During the first quarter of 2020, as discussed in greater detail below, we concluded that we had a triggering event related to our Fine Arts reporting unit, requiring us to perform an 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 following is a discussion regarding (i) the reporting units at which level we tested goodwill for impairment as of October 1, 2019, (ii) changes to the composition of our reporting units between October 1, 2019 and December 31, 2019, (iii) interim goodwill impairment review for our Fine Arts reporting unit during the first quarter of 2020 and (iv) the reporting units at which level we tested goodwill for impairment as of October 1, 2020 and the composition of these reporting units at December 31, 2020 (including the amount of goodwill associated with each reporting unit). When changes occur in the composition of one or more reporting units, the goodwill is reassigned to the reporting units affected based upon their relative fair values.

GOODWILL IMPAIRMENT ANALYSIS - 2019

I. REPORTING UNITS AS OF OCTOBER 1, 2019

Our reporting units at which level we performed our goodwill impairment analysis as of October 1, 2019 were as follows:



•North American Records and Information Management •North American Data Management •Fine Arts •Entertainment Services	•Western Europe •Northern/Eastern Europe and Middle East and India (“NEE and MEI”) •Latin America	•Australia, New Zealand and South Africa (“ANZ SA”) •Asia •Global Data Center

We concluded that the goodwill associated with each of our reporting units was not impaired as of such date.

II. CHANGES TO COMPOSITION OF REPORTING UNITS BETWEEN OCTOBER 1, 2019 AND DECEMBER 31, 2019

During the fourth quarter of 2019, as a result of the realignment of our global managerial structure and changes to our internal financial reporting associated with Project Summit, we reassessed the composition of our reportable operating segments (see Note 10 for a description and definitions of our reporting operating segments) as well as our reporting units.



We noted the following changes to our reporting units: •our former North American Records and Information Management (excluding our technology escrow services business) and North American Data Management reporting units are now being managed as our “North America RIM” reporting unit; •our former Western Europe and NEE and MEI reporting units (excluding India) and our business in Africa, which was previously managed as a component of our former ANZ SA reporting unit, is now being managed together as our “Europe RIM” reporting unit; •our business in India, which was previously managed as a component of our former NEE and MEI reporting unit, is now being managed in conjunction with our businesses in Asia as our “Asia RIM” reporting unit; •our former ANZ SA reporting unit will no longer include South Africa and will be referred to as our “Australia and New Zealand RIM” (“ANZ RIM”) reporting unit; and •our technology escrow services business is now being managed separately as our “Technology Escrow Services” reporting unit.

GOODWILL IMPAIRMENT ANALYSIS - 2020

I. INTERIM GOODWILL IMPAIRMENT REVIEW - FINE ARTS

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. 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. Factors that may impact these assumptions include, but are not limited to: (i) our ability to maintain, or grow, storage and retail service revenues in this reporting unit in line with current expectations and (ii) our ability to manage our fixed and variable costs in this reporting unit in line with potential future revenue declines.

II. REPORTING UNITS AS OF OCTOBER 1, 2020

Our reporting units at which level we performed our goodwill impairment analysis as of October 1, 2020 were as follows:



•North America RIM •Europe RIM •Latin America RIM	•ANZ RIM •Asia RIM •Global Data Center	•Fine Arts •Entertainment Services •Technology Escrow Services

We concluded that the goodwill associated with each of our reporting units was not impaired as of such date. There were no changes to the composition of our reporting units between October 1, 2020 and December 31, 2020.

GOODWILL BY REPORTING UNIT AS OF DECEMBER 31, 2020

The carrying value of goodwill, net for each of our reporting units described above as of December 31, 2020 is as follows:


SEGMENT	REPORTING UNIT	CARRYING VALUE AS OF DECEMBER 31, 2020
Global RIM Business	North America RIM	$	2,719,182
Europe RIM	641,621
Latin America RIM	117,834

Corporate and Other Business	Fine Arts	15,176
Entertainment Services	35,159
Technology Escrow Services	46,105
Total		$	4,557,609

Reporting unit valuations have generally been determined using a combined approach based on the present value of future cash flows (the “Discounted Cash Flow Model”) and market multiples (the “Market Approach”).



The Discounted Cash Flow Model incorporates significant assumptions including future revenue growth rates, operating margins, discount rates and capital expenditures.			The Market Approach requires us to make assumptions related to Adjusted EBITDA (as defined in Note 10) multiples.

Changes in economic and operating conditions impacting these assumptions or changes in multiples could result in goodwill impairments in future periods. In conjunction with our annual goodwill impairment reviews, we reconcile the sum of the valuations of all of our reporting units to our market capitalization as of such dates.

The changes in the carrying value of goodwill attributable to each reportable operating segment for the years ended December 31, 2020 and 2019 are as follows:

L. FINITE-LIVED INTANGIBLE ASSETS AND LIABILITIES

I. CUSTOMER RELATIONSHIP INTANGIBLE ASSETS

Customer relationship intangible assets, which are acquired through either business combinations or acquisitions of customer relationships, are amortized over periods ranging from 10 to 30 years. Customer relationship intangible assets are recorded based upon estimates of their fair value.

II. CUSTOMER INDUCEMENTS

Payments that are made to a customer’s current records management vendor in order to terminate the customer’s existing contract with that vendor (“Permanent Withdrawal Fees”), or direct payments to a customer for which no distinct benefit is received in return, are collectively referred to as "Customer Inducements". Customer Inducements are treated as a reduction of the transaction price over periods ranging from one to 10 years and are included in storage and service revenue in the accompanying Consolidated Statements of Operations. If the customer terminates its relationship with us, the unamortized carrying value of the Customer Inducement intangible asset is charged to revenue. However, in the event of such termination, we generally collect, and record as income, permanent removal fees that generally equal or exceed the amount of the unamortized Customer Inducement intangible asset.

III. DATA CENTER INTANGIBLE ASSETS AND LIABILITIES

Finite-lived intangible assets associated with our Global Data Center Business consist of the following:

DATA CENTER IN-PLACE LEASE INTANGIBLE ASSETS AND DATA CENTER TENANT RELATIONSHIP INTANGIBLE ASSETS

Data Center In-Place Lease Intangible Assets (“Data Center In-Place Leases”) and Data Center Tenant Relationship Intangible Assets (“Data Center Tenant Relationships”) reflect the value associated with acquiring a data center operation with active tenants as of the date of acquisition. The value of Data Center In-Place Leases is determined based upon an estimate of the economic costs (such as lost revenues, tenant improvement costs, commissions, legal expenses and other costs to acquire new data center leases) avoided by acquiring a data center operation with active tenants that would have otherwise been incurred if the data center operation was purchased vacant. Data Center In-Place Leases are amortized over the weighted average remaining term of the acquired data center leases. The value of Data Center Tenant Relationships is determined based upon an estimate of the economic costs avoided upon lease renewal of the acquired tenants, based upon expectations of lease renewal. Data Center Tenant Relationships are amortized over the weighted average remaining anticipated life of the relationship with the acquired tenant.

DATA CENTER ABOVE-MARKET AND BELOW-MARKET IN-PLACE LEASE INTANGIBLE ASSETS

We record Data Center Above-Market In-Place Lease Intangible Assets (“Data Center Above-Market Leases”) and Data Center Below-Market In-Place Lease Intangible Assets (“Data Center Below-Market Leases”) at the net present value of the difference between (i) the contractual amounts to be paid pursuant to each in-place lease and (ii) management’s estimate of the fair market lease rates for each corresponding in-place lease. Data Center Above-Market Leases and Data Center Below-Market Leases are amortized over the remaining non-cancellable term of the acquired in-place lease to storage revenue.

M. DEFERRED FINANCING COSTS

Deferred financing costs are amortized over the life of the related debt. If debt is retired early, the related unamortized deferred financing costs are written-off in the period the debt is retired to Other expense (income), net. See Note 6.

N. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

Every derivative instrument is required to be recorded in the balance sheet as either an asset or a liability measured at its fair value. Periodically, we acquire derivative instruments that are intended to hedge either cash flows or values that are subject to foreign exchange or other market price risk and not for trading purposes. We have formally documented our hedging relationships, including identification of the hedging instruments and the hedged items, as well as our risk management objectives and strategies for undertaking each hedge transaction. Given the recurring nature of our revenues and the long-term nature of our asset base, we have the ability and the preference to use long-term, fixed interest rate debt to finance our business, thereby preserving our long-term returns on invested capital. We may use interest rate swaps as a tool to maintain our targeted level of fixed rate debt. In addition, we may enter into cross-currency swaps to hedge the variability of exchange rates between the United States and our foreign subsidiaries, as well as interest rates. We may also use borrowings in foreign currencies, either obtained in the United States or by our foreign subsidiaries, to hedge foreign currency risk associated with our international investments. As of December 31, 2020 and 2019, none of our derivative instruments contained credit-risk related contingent features. See Note 5.

O. FAIR VALUE MEASUREMENTS

Entities are permitted under GAAP to elect to measure certain financial instruments and certain other items at either fair value or cost. We have elected the cost measurement option in all circumstances where we had an option.

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 and measured on a recurring basis as of December 31, 2020 and 2019, respectively, are as follows:


			FAIR VALUE MEASUREMENTS AT DECEMBER 31, 2020 USING
DESCRIPTION	TOTAL CARRYING VALUE AT DECEMBER 31, 2020		QUOTED PRICES IN ACTIVE MARKETS (LEVEL 1)			SIGNIFICANT OTHER OBSERVABLE INPUTS (LEVEL 2)			SIGNIFICANT UNOBSERVABLE INPUTS (LEVEL 3)
Money Market Funds(1)	$	62,657	$	—		$	62,657		$	—
Time Deposits(1)	2,121		—			2,121			—
Trading Securities	10,892		10,636		(2)	256		(3)	—
Derivative Liabilities(4)	49,703		—			49,703			—


			FAIR VALUE MEASUREMENTS AT DECEMBER 31, 2019 USING

Trading Securities	10,732		10,168		(2)	564		(3)	—
Derivative Liabilities(4)	9,756		—			9,756			—

(1)Money market funds and time deposits are measured based on quoted prices for similar assets and/or subsequent transactions.

(2)Certain trading securities are measured at fair value using quoted market prices.

(3)Certain trading securities are measured based on inputs other than quoted market prices that are observable.

(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 5 for additional information on our derivative financial instruments.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

We did not have any material items that are measured at fair value on a non-recurring basis for the years ended December 31, 2020, 2019, and 2018, with the exception of: (i) the reporting units as presented in our goodwill impairment analysis (as disclosed in Note 2.k.); (ii) the assets and liabilities acquired through acquisitions (as disclosed in Note 3); (iii) the redemption value of certain redeemable noncontrolling interests (as disclosed in Note 2.p.); and (iv) our initial investments in the Frankfurt JV, the MakeSpace JV and OSG (each as defined in Note 3), 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 6. Long-term debt is measured at cost in our Consolidated Balance Sheets as of December 31, 2020 and 2019.

P. REDEEMABLE NONCONTROLLING INTERESTS

Certain unaffiliated third parties own noncontrolling interests in certain of our foreign consolidated subsidiaries. The underlying agreements between us and our noncontrolling interest shareholders for these subsidiaries contain provisions under which the noncontrolling interest shareholders can require us to purchase their respective interests in such subsidiaries at certain times and at a purchase price as stipulated in the underlying agreements (generally at fair value). These put options make these noncontrolling interests redeemable and, therefore, these noncontrolling interests are classified as temporary equity outside of stockholders’ equity. Redeemable noncontrolling interests are reported at the higher of their redemption value or the noncontrolling interest holders’ proportionate share of the underlying subsidiaries net carrying value. Increases or decreases in the redemption value of the noncontrolling interest are offset against Additional Paid-in Capital.

In 2018, one of our noncontrolling interest shareholders exercised its option to put its ownership interest back to us. Upon the exercise of the put option, this noncontrolling interest became mandatorily redeemable by us, and, therefore, is accounted for as a liability rather than a component of redeemable noncontrolling interests. Subject to agreement on final settlement terms and conditions, we and this noncontrolling interest shareholder have agreed in principle on the put option price for the noncontrolling interest shares. We are in dispute with this noncontrolling interest shareholder with respect to whether interest from the date of the put and certain other costs should be reimbursable to the noncontrolling interest shareholder. We intend to vigorously defend that interest and certain other reimbursable costs are not owed to the noncontrolling interest shareholder. We have recorded our estimate of the fair value of these noncontrolling interest shares as a component of Accrued expenses on our Consolidated Balance Sheets as of December 31, 2020 and 2019. It is possible that the value ultimately agreed upon with the noncontrolling interest shareholder could differ from our current estimate of the fair value. Subsequent to these noncontrolling interest shares becoming mandatorily redeemable, any increase or decrease in the fair value of such noncontrolling interest is included as a component of Other expense (income), net on our Consolidated Statements of Operations.

R. REVENUES

Our revenues consist of storage rental revenues as well as service revenues and are reflected net of sales and value-added taxes. Storage rental revenues, which are considered a key driver of financial performance for the storage and information management services industry, consist primarily of recurring periodic rental charges related to the storage of materials or data (generally on a per unit basis) that are typically retained by customers for many years and revenues associated with our data center operations. Service revenues include charges for related service activities, the most significant of which include: (1) the handling of records, including the addition of new records, temporary removal of records from storage, refiling of removed records, customer termination and permanent removal fees, project revenues and courier operations, consisting primarily of the pickup and delivery of records upon customer request; (2) destruction services, consisting primarily of secure shredding of sensitive documents and the subsequent sale of shredded paper for recycling, the price of which can fluctuate from period to period; and (3) digital solutions including scanning, imaging and document conversion services of active and inactive records, and consulting services.

We account for revenue in accordance with ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”). Customers are generally billed monthly based on contractually agreed-upon terms, and storage rental and service revenues are recognized in the month the respective storage rental or service is provided, in line with the transfer of control to the customer. When storage rental fees or services are billed in advance, amounts related to future storage rental or prepaid service contracts are accounted for as deferred revenue and recognized upon the transfer of control to the customer, generally ratably over the contract term. Customer contracts generally include promises to provide monthly recurring storage and related services that are essentially the same over time and have the same pattern of transfer of control to the customer; therefore, most performance obligations represent a promise to deliver a series of distinct services over time (as determined for purposes of ASU 2014-09, a “series”). For those contracts that qualify as a series, we have a right to consideration from the customer in an amount that corresponds directly with the value of the underlying performance obligation transferred to the customer to date. This concept is known as "right to invoice” and we apply the “right to invoice” practical expedient to all revenues, with the exception of storage revenues in our Global Data Center Business (which are subject to leasing guidance). Additionally, each purchasing decision is fully in the control of the customer and; therefore, consideration beyond the current reporting period is variable and allocated to the specific period to which the consideration relates, which is consistent with the practical expedient.

Our Global Data Center Business features storage rental provided to the customer at contractually specified rates over a fixed contractual period. Storage rental revenue related to the storage component of our Global Data Center Business is recognized on a straight-line basis over the contract term in accordance with ASU 2016-02. The revenue related to the service component of our Global Data Center Business is recognized in the period the related services are provided.

The costs associated with the initial movement of customer records into physical storage and certain commissions are considered costs to obtain or fulfill customer contracts (“Contract Fulfillment Costs”). The following describes each of these Contract Fulfillment Costs recognized under ASU 2014-09:

INTAKE COSTS (AND ASSOCIATED DEFERRED REVENUE)

The costs of the initial intake of customer records into physical storage (“Intake Costs”) are deferred and amortized as a component of depreciation and amortization in our Consolidated Statements of Operations over three years, consistent with the transfer of the performance obligation to the customer to which the asset relates. In instances where such Intake Costs are billed to the customer, the associated revenue is deferred and recognized over the same three-year period.

COMMISSIONS

Certain commission payments that are directly associated with the fulfillment of long-term storage contracts are capitalized and amortized as a component of depreciation and amortization in our Consolidated Statements of Operations over three years, consistent with the transfer of the performance obligation to the customer to which the asset relates. Certain direct commission payments associated with contracts with a duration of one year or less are expensed as incurred under the practical expedient which allows an entity to expense as incurred an incremental cost of obtaining a contract if the amortization period of the asset that the entity otherwise would have recognized is one year or less.

DATA CENTER LESSOR CONSIDERATIONS

Our Global 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 ASC 840. 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 Global 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, if accounted for separately, 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 2014-09 if the nonlease components are the predominant components. We have elected to take this practical expedient.

S. 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 (“ESPP”) (together, "Employee Stock-Based Awards”).

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 1 (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 1 of the year of the grant, will be expensed between the date of grant and July 1 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. If an employee retires and has met the 2019 Retirement Criteria, stock options will remain exercisable for up to three years 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.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Stock-based compensation expense for Employee Stock-Based Awards included in the accompanying Consolidated Statements of Operations for the years ended December 31, 2020, 2019 and 2018 is as follows:


	YEAR ENDED DECEMBER 31,
	2020		2019		2018
Stock-based compensation expense	$	37,674	$	35,654	$	31,167
Stock-based compensation expense, after tax	36,584		33,103		28,998

The substantial majority of stock-based compensation expense for Employee Stock-Based Awards is included in Selling, general and administrative expenses in the accompanying Consolidated Statements of Operations.

STOCK OPTIONS

Options are generally granted with exercise prices equal to the market price of the stock on the date of grant; however, in certain instances, options are granted at prices greater than the market price of the stock on the date of grant. The substantial majority of options we issue become exercisable ratably over a period three years from the date of grant and have a contractual life of 10 years from the date of grant, unless the holder’s employment is terminated sooner. Our non-employee directors are considered employees for purposes of our stock option plans and stock option reporting.

The substantial majority of the stock options outstanding at December 31, 2020 are based on the three-year vesting period (10 year contractual life) described above.

Our equity compensation plans generally provide that, upon a vesting change in control (as defined in each plan), any unvested options and other awards granted thereunder shall vest immediately if an employee is terminated as a result of the change in control or terminates their own employment for good reason (as defined in each plan). On January 20, 2015, our stockholders approved the adoption of the Iron Mountain Incorporated 2014 Stock and Cash Incentive Plan, as amended (the "2014 Plan”). Under the 2014 Plan, the total amount of shares of common stock reserved and available for issuance pursuant to awards granted under the 2014 Plan is 12,750,000. The 2014 Plan permits us to continue to grant awards through May 24, 2027.

A total of 48,253,839 shares of common stock have been reserved for grants of options and other rights under our various stock incentive plans, including the 2014 Plan. The number of shares available for grant under our various stock incentive plans, not including the ESPP, at December 31, 2020 was 2,818,706.

The weighted average fair value of stock options granted in 2020, 2019 and 2018 was $2.35, $3.58 and $3.50 per share, respectively. These values were estimated on the date of grant using the Black-Scholes option pricing model. The weighted average assumptions used for grants in the years ended December 31, 2020, 2019 and 2018 are as follows:


	YEAR ENDED DECEMBER 31,
WEIGHTED AVERAGE ASSUMPTIONS	2020		2019		2018
Expected volatility(1)	25.4	%	24.3	%	25.4	%
Risk-free interest rate(2)	1.45	%	2.47	%	2.65	%
Expected dividend yield(3)	7	%	7	%	7	%
Expected life(4)	10.0 years		5.0 years		5.0 years

(1)Expected volatility is calculated utilizing daily historical volatility over a period that equates to the expected life of the option.

(2)Risk-free interest rate is based on the United States Treasury interest rates whose term is consistent with the expected life (estimated period of time outstanding) of the stock options.

(3)Expected dividend yield is considered in the option pricing model and represents our current annualized expected per share dividends over the current trade price of our common stock.

(4)Expected life of the stock options granted is estimated using the historical exercise behavior of employees.

RESTRICTED STOCK UNITS

Our RSUs generally have a vesting period of three years from the date of grant. However, RSUs granted to our non-employee directors vest immediately upon grant. All RSUs accrue dividend equivalents associated with the underlying stock as we declare dividends. Dividends will generally be paid to holders of RSUs in cash upon the vesting date of the associated RSU and will be forfeited if the RSU does not vest. The fair value of RSUs is the excess of the market price of our common stock at the date of grant over the purchase price (which is typically zero).

The fair value of RSUs vested during the years ended December 31, 2020, 2019 and 2018, are as follows:


	YEAR ENDED DECEMBER 31,
	2020		2019		2018

Non-vested at December 31, 2020	1,294,006	$	33.02

PERFORMANCE UNITS

The PUs we issue vest based on our performance against predefined operational and share based targets. PUs granted in 2018 vest based on targets for revenue, Adjusted EBITDA, and total return on our common stock in relation to the MSCI United States REIT Index ("TSR Target") and the number of PUs earned may range from 0% to 200% of the initial award. For awards granted in 2019 and thereafter, the vesting is subject to a minimum level of return on invested capital (“ROIC”) in the third year of the performance period, and thereafter the number of PUs earned is based on (i) the revenue performance for each year averaged at the end of the three-year performance period, (ii) the revenue exit rate of new products in the last quarter of the three-year performance period and (iii) a TSR Target. With respect to the PUs granted in 2019 and thereafter, the number of PUs earned may range from 0% to 219% of the initial award.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

All of our PUs will be settled in shares of our common stock and are subject to cliff vesting three years from the date of the original PU grant. As detailed above, PUs granted:

On or after February 20, 2019, are subject to the 2019 Retirement Criteria. 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.
Prior to February 20, 2019, employees who terminate their employment during the three-year performance period and on or after attaining age 55 and completing 10 years of qualifying service are eligible for pro-rated vesting, subject to the actual achievement against the predefined targets or a market condition as discussed above, based on the number of full years of service completed following the grant date (but delivery of the shares remains deferred).

As a result, PUs are generally expensed over the three-year performance period.

All PUs accrue dividend equivalents associated with the underlying stock as we declare dividends. Dividends will generally be paid to holders of PUs in cash upon the settlement date of the associated PU and will be forfeited if the PU does not vest.

During the years ended December 31, 2020, 2019 and 2018, we issued 425,777, 380,856 and 353,507 PUs, respectively. We forecast the likelihood of achieving the predefined targets for our PUs in order to calculate the expected PUs to be earned. We record a compensation charge based on either the forecasted PUs to be earned (during the performance period) or the actual PUs earned (at the three-year anniversary of the grant date) over the vesting period for each of the awards. The fair value of PUs based on our performance against predefined targets is the excess of the market price of our common stock at the date of grant over the purchase price (which is typically zero). For PUs earned based on a market condition, we utilize a Monte Carlo simulation to fair value these awards at the date of grant, and such fair value is expensed over the three-year performance period. As of December 31, 2020, we expected 100%, 100% and 0% achievement of the predefined targets associated with the awards of PUs made in 2020, 2019 and 2018, respectively.

The fair value of earned PUs that vested during the years ended December 31, 2020, 2019 and 2018, is as follows:


	YEAR ENDED DECEMBER 31,
	2020		2019		2018

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

EMPLOYEE STOCK PURCHASE PLAN

We offer an ESPP in which participation is available to substantially all United States and Canadian employees who meet certain service eligibility requirements. The ESPP provides for the purchase of our common stock by eligible employees through successive offering periods. We have historically had two six-month offering periods per year, the first of which generally runs from June 1 through November 30 and the second of which generally runs from December 1 through May 31. During each offering period, participating employees accumulate after-tax payroll contributions, up to a maximum of 15% of their compensation, to pay the purchase price at the end of the offering. Participating employees may withdraw from an offering before the purchase date and obtain a refund of the amounts withheld as payroll deductions. At the end of the offering period, outstanding options under the ESPP are exercised, and each employee’s accumulated contributions are used to purchase our common stock. The price for shares purchased under the ESPP is 95% of the fair market price at the end of the offering period, without a look-back feature. As a result, we do not recognize compensation expense for the ESPP shares purchased. For the years ended December 31, 2020, 2019 and 2018, there were 159,853, 129,505 and 119,123 shares, respectively, purchased under the ESPP. As of December 31, 2020, we have 216,287 shares available under the ESPP.

As of December 31, 2020, unrecognized compensation cost related to the unvested portion of our Employee Stock-Based Awards was $39,056 and is expected to be recognized over a weighted-average period of 1.7 years.

We issue shares of our common stock for the exercises of stock options, and the vesting of RSUs, PUs and shares of our common stock under our ESPP from unissued reserved shares.

T. OTHER EXPENSE (INCOME), NET

Consolidated other expense (income), net for the years ended December 31, 2020, 2019 and 2018 consists of the following:


	YEAR ENDED DECEMBER 31,
	2020		2019		2018

Other Expense (Income), Net	$	143,545	$	33,898	$	(11,692)

(1)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, includes gains or losses primarily related to (i) borrowings in certain foreign currencies under our Revolving Credit Facility (as defined in Note 6), (ii) our previously outstanding Euro Notes (as defined in Note 6), (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 5).

(2)Other, net for the year ended December 31, 2020 consists primarily of changes in the estimated value of our mandatorily redeemable noncontrolling interests as well as losses on our equity method investments.

U. INCOME TAXES

Accounting for income taxes requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the tax and financial reporting bases of assets and liabilities and for loss and credit carryforwards. Valuation allowances are provided when recovery of deferred tax assets does not meet the more likely than not standard as defined in GAAP. We have elected to recognize interest and penalties associated with uncertain tax positions as a component of the Provision (benefit) for income taxes in the accompanying Consolidated Statements of Operations.

V. 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 years ended December 31, 2020, 2019 and 2018 is as follows:

In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”), which makes a number of changes meant to add, modify or remove certain disclosure requirements associated with the movement of our financial assets and liabilities among the three levels of the fair value hierarchy. We adopted ASU 2018-13 on January 1, 2020. ASU 2018-13 did not have a material impact on our consolidated financial statements.

OTHER AS YET ADOPTED ACCOUNTING PRONOUNCEMENTS

In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848) (“ASU 2020-04”). ASU 2020-04 provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions, for a limited period of time, to ease the potential burden of recognizing the effects of reference rate reform on financial reporting. The amendments in ASU 2020-04 apply to contracts, hedging relationships and other transactions that reference the London Inter-Bank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued due to the global transition away from LIBOR and certain other interbank offered rates. An entity may elect to apply the amendments provided by ASU 2020-04 beginning March 12, 2020 through December 31, 2022. We are currently evaluating these amendments as they relate to our contracts, hedging relationships and other transactions that reference LIBOR, as well as the impact of ASU 2020-04 on our consolidated financial statements.

In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740) (“ASU 2019-12”). ASU 2019-12 simplifies the accounting for income taxes by removing certain exceptions for recognizing deferred taxes for investments, performing intra-period allocation and calculating income taxes in interim periods. ASU 2019-12 also adds guidance to reduce complexity in certain areas, including recognizing deferred taxes for tax goodwill and allocating taxes to members of a consolidated group. ASU 2019-12 is effective for us on January 1, 2021. We do not expect that ASU 2019-12 will have a material impact on our consolidated financial statements.

3. ACQUISITIONS AND JOINT VENTURES

ACQUISITIONS

We account for acquisitions using the acquisition method of accounting, and, accordingly, the assets and liabilities acquired are recorded at their estimated fair values and the results of operations for each acquisition have been included in our consolidated results from their respective acquisition dates.

A. ACQUISITIONS COMPLETED DURING THE YEAR ENDED DECEMBER 31, 2020

Prior to January 9, 2020, we owned a 25% equity interest in OSG Records Management (Europe) Limited ("OSG"). On January 9, 2020, we acquired the remaining 75% equity interest in OSG for cash consideration of approximately $95,500 (the "OSG Acquisition"). The OSG Acquisition enabled us to extend our Global RIM Business in Russia, Ukraine, Kazakhstan, Belarus, and Armenia. The results of OSG are fully consolidated within our consolidated financial statements from the closing date of the OSG Acquisition. In connection with the OSG Acquisition, our previously held 25% equity investment in OSG was remeasured to fair value at the closing date of the OSG Acquisition; as a result, we recorded a gain of approximately $10,000 during the first quarter of 2020, which is included as a component of Other expense (income), net on our Consolidated Statements of Operations. The fair value of the 25% equity investment in OSG was determined based on the purchase price of the OSG Acquisition.

On February 17, 2020, in order to enhance our existing operations in the United Arab Emirates, we acquired Glenbeigh Records Management DWC-LLC, a storage and records management company, for total cash consideration of approximately $29,100.

B. ACQUISITIONS COMPLETED DURING THE YEAR ENDED DECEMBER 31, 2019

During the year ended December 31, 2019, in order to enhance our existing operations in the United States, Colombia, Germany, Hong Kong, Latvia, Slovakia, Switzerland, Thailand and the United Kingdom and to expand our operations into Bulgaria, we completed the acquisition of 10 storage and records management companies and one art storage company for total cash consideration of approximately $51,000. The individual purchase prices of these acquisitions ranged from approximately $700 to $12,500.

At the closing of the IODC Transaction, we paid approximately $1,347,000. In February 2019, we paid approximately $31,000 in additional purchase price associated with the execution of customer contracts from the closing through the one-year anniversary of the IODC Transaction, which, net of amortization, is reported as a third-party commissions asset as a component of Other within Other assets, net in our Consolidated Balance Sheets at December 31, 2020 and 2019.

OTHER 2018 NOTEWORTHY ACQUISITIONS

On May 25, 2018, in order to further expand our data center operations in Europe, we acquired EvoSwitch Netherlands B.V. and EvoSwitch Global Services B.V., a data center colocation space and solutions provider with a data center in Amsterdam (the “EvoSwitch Transaction”), for (i) cash consideration of 189,000 Euros (or approximately $222,000, based upon the exchange rate between the Euro and the United States dollar on the closing date of the EvoSwitch Transaction) and (ii) $25,000 of additional consideration in the form of future services we will provide to the seller, which is included in purchase price holdbacks and other in the allocation of the purchase price paid table below.

On March 8, 2018, in order to expand our data center operations into Europe and Asia, we acquired the operations of two data centers in London and Singapore from Credit Suisse International and Credit Suisse AG (together, “Credit Suisse”) for a total of (i) 34,600 British pounds sterling and (ii) 81,000 Singapore dollars (or collectively, approximately $111,400, based upon the exchange rates between the United States dollar and the British pound sterling and Singapore dollar on the closing date of the Credit Suisse transaction) (the “Credit Suisse Transaction”). As part of the Credit Suisse Transaction, Credit Suisse entered into a long-term lease with us to maintain existing data center operations.

In addition to the transactions noted above, during 2018, in order to enhance our existing operations in the United States, Brazil, China, India, Ireland, Philippines, South Korea and the United Kingdom and to expand our operations into Croatia, we completed the acquisition of 11 storage and records management companies and three art storage companies for total consideration of approximately $98,100. The individual purchase prices of these acquisitions ranged from approximately $1,000 to $34,100.

3. ACQUISITIONS AND JOINT VENTURES (CONTINUED)

Allocations of the purchase price for acquisitions are based on estimates of the fair value of the net assets acquired and are subject to adjustment upon the finalization of the purchase price allocations. The accounting for business combinations requires estimates and judgments regarding expectations for future cash flows of the acquired business, and the allocations of those cash flows to identifiable tangible and intangible assets, in determining the assets acquired and liabilities assumed. The fair values assigned to tangible and intangible assets acquired and liabilities assumed, including contingent consideration, are based on management’s best estimates and assumptions, as well as other information compiled by management, including valuations that utilize customary valuation procedures and techniques. The estimates and assumptions underlying the initial valuations are subject to the collection of information necessary to complete the valuations within the measurement periods, which are up to one year from the respective acquisition dates.

As the valuation of certain assets and liabilities for purposes of purchase price allocations are preliminary in nature, they are subject to adjustment as additional information is obtained about the facts and circumstances regarding these assets and liabilities that existed at the acquisition date. Any adjustments to our estimates of purchase price allocation will be made in the periods in which the adjustments are determined 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 fourth quarter of 2020 and year ended December 31, 2020 were not material to our results from operations.

JOINT VENTURES

A. FRANKFURT DATA CENTER JOINT VENTURE

In October 2020, we formed a joint venture (the “Frankfurt JV”) with AGC Equity Partners (“AGC”) to design and develop a 280,000 square foot, 27 megawatt, hyperscale data center currently under development in Frankfurt, Germany (the “Frankfurt JV Transaction”). AGC acquired an 80% equity interest in the Frankfurt JV, while we retained a 20% equity interest (the "Frankfurt JV Investment"). The total cash consideration for the 80% equity interest sold to AGC was approximately $105,000. We received approximately $93,300 (gross of certain transaction expenses) upon the closing of the Frankfurt JV, and we are entitled to receive an additional approximately $11,700 upon the completion of development of the data center, which we expect to occur in the second quarter of 2021. In connection with the Frankfurt JV Transaction, we also entered into agreements whereby we will earn various fees, including property management and construction and development fees, for services we are providing to the Frankfurt JV.

As a result of the Frankfurt JV Transaction, we recognized a gain of approximately $24,100, representing the excess of the fair value of the consideration received over the carrying value of the assets, which consisted primarily of land and land development assets which were previously included within our Global Data Center Business segment.

We account for our Frankfurt JV Investment as an equity method investment. At the closing date of the Frankfurt JV Transaction, the fair value of the Frankfurt JV Investment was approximately $23,300. The carrying value of our Frankfurt JV Investment at December 31, 2020 was $26,500, which is presented as a component of Other within Other assets, net in our Consolidated Balance Sheet.

B. MAKESPACE JOINT VENTURE

In March 2019, we formed a joint venture entity (the “MakeSpace JV”) with MakeSpace Labs, Inc., a consumer storage provider (“MakeSpace”). In the second quarter of 2020, we committed to participate in a round of equity funding for the MakeSpace JV whereby we agreed to contribute $36,000 of the $45,000 being raised in installments beginning in May 2020 through October 2021. We account for our investment in the MakeSpace JV as an equity method investment. At December 31, 2020 and 2019, we owned approximately 39% and 34%, respectively, of the outstanding equity in the MakeSpace JV, and the carrying value of our investment in the MakeSpace JV at December 31, 2020 and 2019 was $16,924 and $18,570, respectively, which is presented as a component of Other within Other assets, net in our Consolidated Balance Sheets. See Note 4 for additional detail on the divestment of our consumer storage business that was completed in conjunction with the formation of the MakeSpace JV.

4. DIVESTMENTS

In March 2019, we contributed our customer contracts and certain intellectual property and other assets used by us to operate our consumer storage business in the United States and Canada (the “IM Consumer Storage Assets”) and approximately $20,000 in cash (gross of certain transaction expenses) (the “Cash Contribution”) to the MakeSpace JV (the "Consumer Storage Transaction"), established by us and MakeSpace. Upon the closing of the Consumer Storage Transaction on March 19, 2019, the MakeSpace JV owned (i) the IM Consumer Storage Assets, (ii) the Cash Contribution and (iii) the customer contracts, intellectual property and certain other assets used by MakeSpace to operate its consumer storage business in the United States. As part of the Consumer Storage Transaction, we received an initial equity interest of approximately 34% in the MakeSpace JV (the "MakeSpace Investment"). In connection with the Consumer Storage Transaction and the investment in the MakeSpace JV, we also entered into a storage and service agreement with the MakeSpace JV to provide certain storage and related services to the MakeSpace JV (see Note 11).

We have concluded that the divestment of the IM Consumer Storage Assets in the Consumer Storage Transaction 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 Income (loss) from continuing operations in our Consolidated Statements of Operations for the year ended December 31, 2019 through the closing date of the Consumer Storage Transaction and for the year ended December 31, 2018 and the cash flows associated with this business are presented as a component of cash flows from continuing operations in our Consolidated Statements of Cash Flows for the year ended December 31, 2019 through the closing date of the Consumer Storage Transaction and for the year ended December 31, 2018.

As a result of the Consumer Storage Transaction, we recorded a gain on sale of approximately $4,200 to Other expense (income), net, in the first quarter of 2019, representing the excess of the fair value of the consideration received over the sum of (i) the carrying value of our consumer storage operations and (ii) the Cash Contribution.

5. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

Derivative instruments we are party to include: (i) interest rate swap agreements (which are designated as cash flow hedges), (ii) cross-currency swap agreements (which are designated as net investment hedges) and (iii) foreign exchange currency forward contracts (which are not designated as 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. As of December 31, 2020 and 2019, we had $350,000 in notional value of interest rate swap agreements outstanding, which expire in March 2022. 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.

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 once our current interest rate swap agreements expire in March 2022. The forward-starting interest rate swap agreements have $350,000 in notional value, commence in March 2022 and expire in March 2024. Under the swap agreements, we will receive variable rate interest payments 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, including the forward-starting interest rate swap agreements, as cash flow hedges. Unrealized gains are recognized as assets, while unrealized losses are recognized as liabilities.

5. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES (CONTINUED)

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 rates 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 approximately 300,000 Euros at a weighted average interest rate of approximately 3.4%. These cross-currency swap agreements expire in February 2026 (“February 2026 Cross Currency Swap Agreements”).

We have designated these cross-currency swap agreements as hedge of net investments 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.

FOREIGN EXCHANGE CURRENCY FORWARD CONTRACTS NOT DESIGNATED AS HEDGING INSTRUMENTS

On occasion, we enter into forward contracts to hedge our exposures associated with certain foreign currencies. We have not designated any of these forward contracts as hedges. Our policy is to record the fair value of each derivative instrument on a gross basis. As of December 31, 2020 and 2019, we had no outstanding forward contracts.

EURO NOTES DESIGNATED AS A HEDGE OF NET INVESTMENT

Prior to their redemption in August 2020, we designated a portion of our Euro Notes as a hedge of net investment of certain of our Euro denominated subsidiaries. From January 1, 2020 through the date of redemption and for the years ended December 31, 2019 and 2018 we designated, on average, 300,000, 284,986 and 224,424 Euros, respectively, of our Euro Notes as a hedge of net investment of certain of our Euro denominated subsidiaries. As a result, we recorded the following foreign exchange losses (gains) related to the change in fair value of such debt due to currency translation adjustments as a component of Accumulated other comprehensive items, net:

A. CREDIT AGREEMENT

Our credit agreement (the "Credit Agreement") consists of a revolving credit facility (the “Revolving Credit Facility”) and a term loan (the “Term Loan A”). The Revolving Credit Facility enables IMI and certain of its United States and foreign subsidiaries to borrow in United States dollars and (subject to sublimits) a variety of other currencies (including Canadian dollars, British pounds sterling and Euros, among other currencies) in an aggregate outstanding amount not to exceed $1,750,000. Under the Credit Agreement, we have the option to request additional commitments of up to $1,260,000, in the form of term loans or through increased commitments under the Revolving Credit Facility, subject to the conditions specified in the Credit Agreement. The Credit Agreement is scheduled to mature on June 4, 2023, at which point all obligations become due. The original principal amount of the Term Loan A was $250,000 and is to be paid in quarterly installments in an amount equal to $3,125 per quarter, with the remaining balance due on June 4, 2023.

On December 20, 2019, we entered into an amendment to the Credit Agreement. This amendment amended the definition of EBITDA and certain other definitions and restrictive covenants contained in the Credit Agreement.

IMI and the Guarantors guarantee all obligations under the Credit Agreement. The interest rate on borrowings under the Credit Agreement varies depending on our choice of interest rate and currency options, plus an applicable margin, which varies based on our consolidated leverage ratio. Additionally, the Credit Agreement requires the payment of a commitment fee on the unused portion of the Revolving Credit Facility, which fee ranges from between 0.25% to 0.4% based on our consolidated leverage ratio and fees associated with outstanding letters of credit. As of December 31, 2020, we had no outstanding borrowings under the Revolving Credit Facility and $215,625 aggregate outstanding principal amount under the Term Loan A. At December 31, 2020, we had various outstanding letters of credit totaling $3,232 under the Revolving Credit Facility. The remaining amount available for borrowing under the Revolving Credit Facility as of December 31, 2020, which is based on IMI’s leverage ratio, the last 12 months' earnings before interest, taxes, depreciation and amortization and rent expense (“EBITDAR”), other adjustments as defined in the Credit Agreement and current external debt, was $1,746,768 (which amount represents the maximum availability as of such date). Available borrowings under the Revolving Credit Facility are subject to compliance with our indenture covenants as discussed below. The average interest rate in effect for all outstanding borrowings under the Credit Agreement was 1.9% and 3.3% as of December 31, 2020 and 2019, respectively. The average interest rate in effect under the Revolving Credit Facility was 3.2% as of December 31, 2019, and the interest rate in effect under the Term Loan A as of December 31, 2020 and 2019 was 1.9% and 3.5%, respectively.

IMI’s wholly owned subsidiary, Iron Mountain Information Management, LLC (“IMIM”), has an incremental term loan B with a principal amount of $700,000 (the “Term Loan B”). The Term Loan B, which matures on January 2, 2026, was issued at 99.75% of par. The Term Loan B holders benefit from the same security and guarantees as other borrowings under the Credit Agreement. The Term Loan B holders also benefit from the same affirmative and negative covenants as other borrowings under the Credit Agreement; however, the Term Loan B holders are not generally entitled to the benefits of the financial covenants under the Credit Agreement.

Principal payments on the Term Loan B are to be paid in quarterly installments of $1,750 per quarter during the period June 30, 2018 through December 31, 2025, with the balance due on January 2, 2026. The Term Loan B may be prepaid without penalty at any time. The Term Loan B bears interest at a rate of LIBOR plus 1.75%. As of December 31, 2020, we had $679,621 aggregate outstanding principal amount under the Term Loan B. The interest rate in effect under Term Loan B as of December 31, 2020 and 2019 was 1.9% and 3.6%, respectively.

C. AUSTRALIAN DOLLAR TERM LOAN

Iron Mountain Australia Group Pty, Ltd. (“IM Australia”), a wholly owned subsidiary of IMI, has an AUD term loan with an original principal balance of 350,000 Australian dollars (“AUD Term Loan”). All indebtedness associated with the AUD Term Loan was issued at 99% of par. Principal payments on the AUD Term Loan are to be paid in quarterly installments in an aggregate amount of 8,750 Australian dollars per year. The AUD Term Loan bears interest at BBSY (an Australian benchmark variable interest rate) plus 3.875%. The AUD Term Loan is scheduled to mature on September 22, 2022, at which point all obligations become due.


As of December 31, 2020, we had 316,563 Australian dollars ($244,014 based upon the exchange rate between the United States dollar and the Australian dollar as of December 31, 2020) outstanding on the AUD Term Loan.

D. UK BILATERAL REVOLVING CREDIT FACILITY


IM UK and Iron Mountain (UK) Data Centre Limited has a 140,000 British pounds sterling Revolving Credit Facility (the “UK Bilateral Facility”) with Barclays Bank PLC. The maximum amount permitted to be borrowed under the UK Bilateral Facility is 140,000 British pounds sterling, and we have the option to request additional commitments of up to 125,000 British pounds sterling, subject to the conditions specified in the UK Bilateral Facility. The UK Bilateral Facility is fully drawn. The UK Bilateral Facility is secured by certain properties in the United Kingdom. IMI and the Guarantors guarantee all obligations under the UK Bilateral Facility. The UK Bilateral Facility is scheduled to mature on September 23, 2022, at which point all obligations become due. The UK Bilateral Facility contains an option to extend the maturity date for an additional year, subject to the conditions specified in the UK Bilateral Facility, including the lender’s consent. The UK Bilateral Facility bears interest at a rate of LIBOR plus 2.25%. The interest rate in effect under the UK Bilateral Facility was 2.3% and 3.1% as of December 31, 2020 and 2019, respectively.		MAXIMUM AMOUNT £140,000 OPTIONAL ADDITIONAL COMMITMENTS £125,000

	2.3% Interest Rate
	As of December 31, 2020

E. ACCOUNTS RECEIVABLE SECURITIZATION PROGRAM

We participate in an accounts receivable securitization program (the “Accounts Receivable Securitization Program”) involving several of our wholly owned subsidiaries and certain financial institutions. Under the Accounts Receivable Securitization Program, certain of our subsidiaries sell substantially all of their United States accounts receivable balances to our wholly owned special purpose entities, Iron Mountain Receivables QRS, LLC and Iron Mountain Receivables TRS, LLC (the “Accounts Receivable Securitization Special Purpose Subsidiaries”). The Accounts Receivable Securitization Special Purpose Subsidiaries use the accounts receivable balances to collateralize loans obtained from certain financial institutions. The Accounts Receivable Securitization Special Purpose Subsidiaries are consolidated subsidiaries of IMI. The Accounts Receivable Securitization Program is accounted for as a collateralized financing activity, rather than a sale of assets, and therefore: (i) accounts receivable balances pledged as collateral are presented as assets and borrowings are presented as liabilities on our Consolidated Balance Sheets, (ii) our Consolidated Statements of Operations reflect the associated charges for bad debt expense related to pledged accounts receivable (a component of selling, general and administrative expenses) and reductions to revenue due to billing and service related credit memos issued to customers and related reserves, as well as interest expense associated with the collateralized borrowings and (iii) receipts from customers related to the underlying accounts receivable are reflected as operating cash flows and borrowings and repayments under the collateralized loans are reflected as financing cash flows within our Consolidated Statements of Cash Flows. IMIM retains the responsibility of servicing the accounts receivable balances pledged as collateral for the Accounts Receivable Securitization Program and IMI provides a performance guaranty. The maximum availability allowed is limited by eligible accounts receivable, as defined under the terms of the Accounts Receivable Securitization Program.


On March 31, 2020, we amended the Accounts Receivable Securitization Program to (i) increase the maximum amount available from $275,000 to $300,000 and (ii) extend the maturity date from July 30, 2020 to July 30, 2021, at which point all obligations become due. The full amount outstanding under the Accounts Receivable Securitization Program is classified within the current portion of long-term debt in our Consolidated Balance Sheet as of December 31, 2020 and 2019. As of December 31, 2020, the maximum availability allowed and amount outstanding under the Accounts Receivable Securitization Program was $274,100 and $85,000, respectively. At December 31, 2019, both the maximum availability and amount outstanding under the Accounts Receivable Securitization Program was $272,062. The interest rate in effect under the Accounts Receivable Securitization Program was 1.1% and 2.8% as of December 31, 2020 and 2019, respectively. Commitment fees at a rate of 40 basis points are charged on amounts made available but not borrowed under the Accounts Receivable Securitization Program.		MAXIMUM AMOUNT $300,000

F. CASH POOLING

Certain of our subsidiaries participate in cash pooling arrangements (the “Cash Pools”) with Bank Mendes Gans (“BMG”), an independently operated wholly owned subsidiary of ING Group, in order to help manage global liquidity requirements. Under the Cash Pools, cash deposited by participating subsidiaries with BMG is pledged as security against the debit balances of other participating subsidiaries, and legal rights of offset are provided and, therefore, amounts are presented in our Consolidated Balance Sheets on a net basis. Each subsidiary receives interest on the cash balances held on deposit or pays interest on its debit balances based on an applicable rate as defined in the Cash Pools.

We currently utilize two separate Cash Pools with BMG, one of which we utilize to manage global liquidity requirements for our qualified REIT subsidiaries (the “QRS Cash Pool”) and the other for our taxable REIT subsidiaries (the “TRS Cash Pool”). We have executed overdraft facility agreements for the QRS Cash Pool and TRS Cash Pool, each in an amount not to exceed $10,000. Each overdraft facility permits us to cover a temporary net debit position in the applicable pool.

The approximate amount of the net cash position, gross position and outstanding debit balances for the QRS Cash Pool and TRS Cash Pool as of December 31, 2020 and 2019 were as follows:


	DECEMBER 31, 2020						DECEMBER 31, 2019
	GROSS CASH POSITION		OUTSTANDING DEBIT BALANCES		NET CASH POSITION		GROSS CASH POSITION		OUTSTANDING DEBIT BALANCES		NET CASH POSITION
QRS Cash Pool	$	448,700	$	(447,400)	$	1,300	$	372,100	$	(369,000)	$	3,100
TRS Cash Pool	555,500		(553,500)		2,000		319,800		(301,300)		18,500

The net cash position balances as of December 31, 2020 and 2019 are reflected as Cash and cash equivalents in our Consolidated Balance Sheets.

G. LETTERS OF CREDIT

As of December 31, 2020, we had outstanding letters of credit totaling $36,160, of which $3,232 reduce our borrowing capacity under the Revolving Credit Facility (as described above). The letters of credit expire at various dates between January 2021 and January 2033.

H. 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 certain other 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, a net total lease adjusted leverage ratio and a net secured debt 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.

The Credit Agreement uses EBITDAR-based calculations and the bond indentures use EBITDA-based calculations as the primary measures of financial performance for purposes of calculating leverage and fixed charge coverage ratios. The bond indenture EBITDA-based calculations include our consolidated subsidiaries, other than those we have designated as “Unrestricted Subsidiaries” as defined in the 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 December 31, 2020 and 2019. Noncompliance with these leverage and fixed charge coverage ratios would have a material adverse effect on our financial condition.

B. SELF-INSURED LIABILITIES

We are self-insured up to certain limits for costs associated with workers’ compensation claims, vehicle accidents, property and general business liabilities, and benefits paid under employee healthcare and short-term disability programs. At December 31, 2020 and 2019, there were $47,959 and $43,127, respectively, of self-insurance accruals reflected in Accrued expenses on our Consolidated Balance Sheets. The measurement of these costs requires the consideration of historical cost experience and judgments about the present and expected levels of cost per claim. We account for these costs primarily through actuarial methods, which develop estimates of the undiscounted liability for claims incurred, including those claims incurred but not reported. These methods provide estimates of future claim costs based on claims incurred as of the balance sheet date.

C. LITIGATION—GENERAL

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. A portion of the defense and/or settlement costs associated with such litigation is covered by various commercial liability insurance policies purchased by us and, in limited cases, indemnification from third parties. Our policy is to establish reserves for loss contingencies when the losses are both probable and reasonably estimable. We record legal costs associated with loss contingencies as expenses in the period in which they are incurred. While the outcome of 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.

8. STOCKHOLDERS’ EQUITY MATTERS

Our board of directors has adopted a dividend policy under which we have paid, and in the future intend to pay, quarterly cash dividends on our common stock. The amount and timing of future dividends will continue to be subject to the approval of our board of directors, in its sole discretion, and to applicable legal requirements.

In 2018, 2019 and 2020, our board of directors declared the following dividends:

8. STOCKHOLDERS’ EQUITY MATTERS (CONTINUED)

For federal income tax purposes, distributions to our stockholders are generally treated as nonqualified ordinary dividends (potentially eligible for the lower effective tax rates available for “qualified REIT dividends”), qualified ordinary dividends or return of capital. The United States Internal Revenue Service requires historical C corporation earnings and profits to be distributed prior to any REIT distributions, which may affect the character of each distribution to our stockholders, including whether and to what extent each distribution is characterized as a qualified or nonqualified ordinary dividend. In addition, certain of our distributions qualify as capital gain distributions. For the years ended December 31, 2020, 2019, and 2018, the dividends we paid on our common shares were classified as follows:

Dividends paid during the years ended December 31, 2020, 2019, and 2018 which were classified as qualified ordinary dividends for federal income tax purposes primarily related to the distribution of historical C corporation earnings and profits related to certain acquisitions completed during the years ended December 31, 2020, 2019, and 2018. In 2020, the percentage of our dividend that was classified as a capital gain was 49.5% and primarily related to the sale of land and buildings in the United States. In 2019, the percentage of our dividend that was classified as a capital gain was 14.7% and primarily related to the sale of land and buildings in the United States and United Kingdom. In 2018, the percentage of our dividend that was classified as a capital gain was 5.8% and primarily related to the sale of land and buildings in the United Kingdom.

EQUITY OFFERING

In December 2017, we entered into an underwriting agreement (the “Underwriting Agreement”) with a syndicate of 16 banks (the “Underwriters”) related to the public offering by us of 14,500,000 shares of our common stock. In January 2018, the Underwriters, pursuant to the Underwriting Agreement, exercised an option to purchase an additional 2,175,000 shares of common stock, which after deducting underwriters’ commissions and the per share value of the dividend we declared on our common stock on October 24, 2017, resulted in net proceeds of approximately $76,200.

9. INCOME TAXES

We have been organized and have operated as a REIT effective beginning with our taxable year that ended on December 31, 2014. As a REIT, we are generally permitted to deduct from our federal taxable income the dividends we pay to our stockholders. The income represented by such dividends is not subject to federal taxation at the entity level but is taxed, if at all, at the stockholder level. The income of our domestic taxable REIT subsidiaries (“TRSs”), which hold our domestic operations that may not be REIT-compliant as currently operated and structured, is subject, as applicable, to federal and state corporate income tax. In addition, we and our subsidiaries continue to be subject to foreign income taxes in other jurisdictions in which we have business operations or a taxable presence, regardless of whether assets are held or operations are conducted through subsidiaries disregarded for federal income tax purposes or TRSs. We will also be subject to a separate corporate income tax on any gains recognized on the sale or disposition of any asset previously owned by a C corporation during a five-year period after the date we first owned the asset as a REIT asset that are attributable to “built-in gains” with respect to that asset on that date. We will also be subject to a built-in gains tax on our depreciation recapture recognized into income as a result of accounting method changes in connection with our acquisition activities. If we fail to remain qualified for taxation as a REIT, we will be subject to federal income tax at regular corporate income tax rates. Even if we remain qualified for taxation as a REIT, we may be subject to some federal, state, local and foreign taxes on our income and property in addition to taxes owed with respect to our TRS operations. In particular, while state income tax regimes often parallel the federal income tax regime for REITs, many states do not completely follow federal rules and some do not follow them at all.

The significant components of our deferred tax assets and deferred tax liabilities as of December 31, 2020 and 2019 are presented below:


	DECEMBER 31,

At December 31, 2020, we have federal and state net operating loss carryforwards of which we are expecting an insignificant tax benefit to be realized. We have assets for foreign net operating losses of $92,142, with various expiration dates (and in some cases no expiration date), subject to a valuation allowance of approximately 43%.

9. INCOME TAXES (CONTINUED)

A reconciliation of total income tax expense and the amount computed by applying the current federal statutory tax rate of 21.0% to income (loss) from continuing operations before provision (benefit) for income taxes for the years ended December 31, 2020, 2019 and 2018, respectively, is as follows:


	YEAR ENDED DECEMBER 31,
	2020		2019		2018
Computed "expected” tax provision	$	78,268	$	68,910	$	86,165

State taxes (net of federal tax benefit)	2,258		2,115		1,599

Other, net	(4,507)		(45)		(1,363)
Provision (Benefit) for Income Taxes	$	29,609	$	59,931	$	42,753

Our effective tax rates for the years ended December 31, 2020, 2019 and 2018 were 7.9%, 18.3% and 10.4%, respectively. 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 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.

The primary reconciling items between the federal statutory tax rate of 21.0% and our overall effective tax rate were:


YEAR ENDED DECEMBER 31,
2020	2019	2018
The benefit derived from the dividends paid deduction of $60,378 and the impact of differences in the tax rates at which our foreign earnings are subject to, resulting in a tax provision of $9,472.	The benefit derived from the dividends paid deduction of $40,577 and the impact of differences in the tax rates at which our foreign earnings are subject to, resulting in a tax provision of $8,562.	The benefit derived from the dividends paid deduction of $35,165, the impact of differences in the tax rates at which our foreign earnings are subject to, resulting in a tax provision of $1,031 and a discrete tax benefit of approximately $14,000 associated with the resolution of a tax matter (which was included as a component of Accrued expenses in our Consolidated Balance Sheet as of December 31, 2017).

As a REIT, we are entitled to a deduction for dividends paid, resulting in a substantial reduction of federal income tax expense. As a REIT, substantially all of our income tax expense will be incurred based on the earnings generated by our foreign subsidiaries and our domestic TRSs.

9. INCOME TAXES (CONTINUED)

Following our conversion to a REIT in 2014, we concluded that it was not our intent to reinvest our current and future undistributed earnings of our foreign subsidiaries indefinitely outside the United States. As of December 31, 2016, we concluded that it is our intent to indefinitely reinvest our current and future undistributed earnings of certain of our unconverted foreign TRSs outside the United States. With the exception of certain limited instances, we no longer provide incremental foreign withholding taxes on the retained book earnings of these unconverted foreign TRSs, which was approximately $262,379 as of December 31, 2020. As a REIT, future repatriation of incremental undistributed earnings of our foreign subsidiaries will not be subject to federal or state income tax, with the exception of foreign withholding taxes in limited instances; however, such future repatriations will require distribution in accordance with REIT distribution rules, and any such distribution may then be taxable, as appropriate, at the stockholder level. We continue, however, to provide for incremental foreign withholding taxes on net book over outside basis differences related to the earnings of our foreign QRSs and certain other foreign TRSs (excluding unconverted foreign TRSs).

The evaluation of an uncertain tax position is a two-step process. The first step is a recognition process whereby we determine whether it is more likely than not that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. The second step is a measurement process whereby a tax position that meets the more likely than not recognition threshold is calculated to determine the amount of benefit to recognize in the financial statements. The tax position is measured as the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement.

We have elected to recognize interest and penalties associated with uncertain tax positions as a component of the provision (benefit) for income taxes in the accompanying Consolidated Statements of Operations. We recorded a decrease of $1,499 for gross interest and penalties for the year ended December 31, 2020. We recorded an increase of $1,780 and $1,961 for gross interest and penalties for the years ended December 31, 2019 and 2018, respectively. We had $6,212 and $9,282 accrued for the payment of interest and penalties as of December 31, 2020 and 2019, respectively.

A summary of tax years that remain subject to examination by major tax jurisdictions is as follows:


TAX YEARS						TAX JURISDICTION
See Below						United States—Federal and State
2017 to present						United Kingdom
2014 to present						Canada

The normal statute of limitations for United States federal tax purposes is three years from the date the tax return is filed; however, the statute of limitations may remain open for periods longer than three years in instances where a federal tax examination is in progress. The 2019, 2018 and 2017 tax years remain subject to examination for United States federal tax purposes as well as net operating loss carryforwards utilized in these years. We utilized net operating losses from 2002 through 2003 and 2010 through 2015 in our federal income tax returns for these tax years. The normal statute of limitations for state purposes is between three to five years. However, certain of our state statute of limitations remain open for periods longer than this when audits are in progress.

We are subject to income taxes in the United States and numerous foreign jurisdictions. We are subject to examination by various tax authorities in jurisdictions in which we have business operations or a taxable presence. We regularly assess the likelihood of additional assessments by tax authorities and provide for these matters as appropriate. As of December 31, 2020, we had $25,969 of reserves related to uncertain tax positions, of which $23,402 and $2,567 is included in other long-term liabilities and deferred income taxes, respectively, in the accompanying Consolidated Balance Sheet. As of December 31, 2019, we had $35,068 of reserves related to uncertain tax positions, of which $31,992 and $3,076 is included in other long-term liabilities and deferred income taxes, respectively, in the accompanying Consolidated Balance Sheet. Although we believe our tax estimates are appropriate, the final determination of tax audits and any related litigation could result in changes in our estimates.

The reversal of these reserves of $25,969 as of December 31, 2020 will be recorded as a reduction of our income tax provision, if sustained. We believe that it is reasonably possible that an amount up to approximately $2,989 of our unrecognized tax positions may be recognized by the end of 2021 as a result of a lapse of statute of limitations or upon closing and settling significant audits in various worldwide jurisdictions.

10. SEGMENT INFORMATION (CONTINUED)

The accounting policies of the reportable segments are the same as those described in Note 2. During the fourth quarter of 2020, we changed our definition of Adjusted EBITDA to (a) exclude stock-based compensation expense and (b) include our share of Adjusted EBITDA from our unconsolidated joint ventures. All prior periods have been recast to conform to these changes. We now define Adjusted EBITDA for each segment as income (loss) from continuing operations before interest expense, net, provision (benefit) for income taxes, depreciation and amortization (inclusive of our share of Adjusted EBITDA from our unconsolidated joint ventures), and excluding certain items we do not believe to be indicative of our core operating results, specifically:



EXCLUDED
•Significant Acquisition Costs •Restructuring Charges •Intangible impairments •(Gain) loss on disposal/write-down of property, plant and equipment, net (including real estate)			•Other expense (income), net •Stock-based compensation expense •COVID-19 Costs (as defined below)

Internally, we use Adjusted EBITDA as the basis for evaluating the performance of, and allocated resources to, our operating segments.

A reconciliation of Income (Loss) from Continuing Operations to Adjusted EBITDA on a consolidated basis for the years ended December 31, 2020, 2019 and 2018 is as follows:

11. RELATED PARTY TRANSACTIONS

In October 2020, in connection with the Frankfurt JV Transaction, we entered into agreements whereby we will earn various fees, including property management and construction and development fees, for services we are providing to the Frankfurt JV (the “Frankfurt JV Agreements”). Revenues and expenses associated with the Frankfurt JV Agreements are presented as a component of our Global Data Business segment. During the year ended December 31, 2020, we recognized revenue of approximately $400 associated with the Frankfurt JV Agreements.

In March 2019, in connection with the Consumer Storage Transaction and the MakeSpace Investment, we entered into a storage and service agreement with the MakeSpace JV to provide certain storage and related services to the MakeSpace JV (the "MakeSpace Agreement”). Revenues and expenses associated with the MakeSpace Agreement are presented as a component of our Global RIM Business segment.

During the years ended December 31, 2020, 2019 and 2018, the Company had no other related party transactions.

12. PROJECT SUMMIT

In October 2019, we announced Project Summit, our global program designed to better position us for future growth and achievement of our strategic objectives. We expanded Project Summit during the first quarter of 2020 to include additional opportunities to streamline our business and operations, as well as accelerated the timing of certain opportunities previously identified. Such opportunities include leveraging new technology solutions to enable us to modernize our service delivery model and more efficiently utilize our fleet, labor and real estate. As a result of the program, we expect to reduce the number of positions at vice president and above by approximately 45%. The total program is expected to reduce our total managerial and administrative workforce by approximately 700 positions by the end of 2021. We have also reduced our services and operations workforce. As of December 31, 2020, we have completed approximately 70% of our planned workforce reductions. The activities associated with Project Summit began in the fourth quarter of 2019 and are expected to be substantially complete by the end of 2021.

We estimate that the implementation of Project Summit will result in total operating expenditures ("Restructuring Charges") of approximately $450,000 that primarily consist of: (1) employee severance costs; (2) internal costs associated with the development and implementation of Project Summit initiatives; (3) professional fees, primarily related to third party consultants who are assisting with the design and execution of various initiatives as well as project management activities and (4) system implementation and data conversion costs.

Restructuring Charges included in the accompanying Consolidated Statement of Operations for the years ended December 31, 2020 and 2019, and from the inception of Project Summit through December 31, 2020, are as follows:


	YEAR ENDED DECEMBER 31, 2020		YEAR ENDED DECEMBER 31, 2019		FROM THE INCEPTION OF PROJECT SUMMIT THROUGH DECEMBER 31, 2020
