b. Goodwill and Other Intangible Assets and Liabilities

Goodwill

Since December 31, 2017, there have been no changes to our accounting polices related to the accounting for goodwill. As of December 31, 2017 and June 30, 2018, no factors were identified that would alter our October 1, 2017 goodwill impairment analysis. When changes occur in the composition of one or more reporting units, the goodwill is reassigned to the reporting units affected based on their relative fair values.

Our reporting units as of December 31, 2017 are described in detail in Note 2.h. to Notes to Consolidated Financial Statements included in our Annual Report. The goodwill associated with acquisitions completed during the first six months of 2018 (which are described in Note 4) has been incorporated into our reporting units as they existed as of December 31, 2017.

During the first quarter of 2018, as a result of changes in the management of our businesses included in our Other International Business segment, we reassessed the composition of our reporting units. As a result of this reassessment, we determined that our business in South Africa, which was previously being managed in conjunction with our businesses in Northern and Eastern Europe and Middle East and India as a part of our former Northern and Eastern Europe and Middle East, Africa and India (“NEE and MEAI”) reporting unit, was now being managed in conjunction with our businesses included in our Australia and New Zealand reporting unit. This newly formed reporting unit, which consists of (i) the businesses included in our former Australia and New Zealand reporting unit and (ii) our business in South Africa is referred to as the Australia, New Zealand and South Africa (“ANZ-SA”) reporting unit. The former NEE and MEAI reporting unit is now referred to as the Northern and Eastern Europe and Middle East and India ("NEE and MEI") reporting unit.

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 and are included in depreciation and amortization in the accompanying Condensed Consolidated Statements of Operations. The value of customer relationship intangible assets is calculated based upon estimates of their fair value.

ii. Customer Inducements

Prior to the adoption of ASU 2014-09, free intake costs to transport boxes to one of our facilities, which include labor and transportation costs ("Free Move Costs"), were capitalized and amortized over periods ranging from 10 to 30 years. The amortization of Free Move Costs is included in depreciation and amortization in the accompanying Condensed Consolidated Statements of Operations for the three and six months ended June 30, 2017. Subsequent to the adoption of ASU 2014-09, Free Move Costs are considered a Contract Fulfillment Cost (as defined in Note 2.c.) and, therefore, are now deferred and amortized over three years, consistent with the transfer of the performance obligation to the customer to which the asset relates. See Note 2.c. for information regarding the accounting for Free Move Costs, which are now a component of Intake Costs (as defined in Note 2.c.), following the adoption of ASU 2014-09.

Payments that are made to a customer's current records management vendor in order to terminate the customer's existing contract with that vendor, or direct payments to a customer ("Permanent Withdrawal Fees"), are amortized over periods ranging from 5 to 15 years and are included in storage and service revenue in the accompanying Condensed Consolidated Statements of Operations. Our accounting for Permanent Withdrawal Fees did not change as a result of the adoption of ASU 2014-09.

Free Move Costs (prior to the adoption of ASU 2014-09) and Permanent Withdrawal Fees are collectively referred to as "Customer Inducements". If the customer terminates its relationship with us, the unamortized carrying value of the Customer Inducement intangible asset is charged to expense or 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 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") are acquired through either business combinations or asset acquisitions in our data center business. These intangible assets 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 and unreimbursed operating expenses during the lease-up period, 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 and are included in depreciation and amortization in the accompanying Condensed Consolidated Statements of Operations. 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 and are included in depreciation and amortization in the accompanying Condensed Consolidated Statements of Operations. Data Center In-Place Leases and Data Center Tenant Relationships are included in Customer relationships, customer inducements and data center lease-based intangibles in the accompanying Condensed Consolidated Balance Sheets.

Data Center Above-Market and Below-Market In-Place Lease Intangible Assets

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”) are acquired through either business combinations or asset acquisitions in our data center business. We record Data Center Above-Market Leases and 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 in the accompanying Condensed Consolidated Statements of Operations. Data Center Above-Market Leases are included in Customer relationships, customer inducements and data center lease-based intangibles in the accompanying Condensed Consolidated Balance Sheets. Data Center Below-Market Leases are included in Other long-term liabilities in the accompanying Condensed Consolidated Balance Sheets.

c. Revenues

In May 2014, the Financial Accounting Standards Board ("FASB") issued ASU 2014-09. ASU 2014-09 provides guidance for management to reassess revenue recognition as it relates to: (1) transfer of control, (2) variable consideration, (3) allocation of transaction price based on relative standalone selling price, (4) licenses, (5) time value of money, and (6) contract costs. We adopted ASU 2014-09 as of January 1, 2018 using the modified retrospective method for all of our customer contracts, whereby the cumulative effect of applying ASU 2014-09 is recognized at the date of initial application. At January 1, 2018, we recognized the cumulative effect of initially applying ASU 2014-09 as an adjustment to the opening balance of (distributions in excess of earnings) earnings in excess of distributions, resulting in a decrease of $30,233 to stockholders' equity. The reduction of (distribution in excess of earnings) earnings in excess of distributions represents the net effect of (i) the write-off of Free Move Costs, net (which were capitalized and amortized prior to the adoption of ASU 2014-09) based upon the net book value of the Free Move Costs as of December 31, 2017, (ii) the recognition of certain Contract Fulfillment Costs, specifically Intake Costs (each as defined below) and commission assets, (iii) the recognition of deferred revenue associated with Intake Costs billed to our customers (as discussed below), and (iv) the deferred income tax impact of the aforementioned items. As we adopted ASU 2014-09 on a modified retrospective basis, the comparative Condensed Consolidated Balance Sheet as of December 31, 2017, the Condensed Consolidated Statements of Operations and the Condensed Consolidated Statements of Comprehensive Income (Loss) for the three and six months ended June 30, 2017 and the Condensed Consolidated Statement of Equity and the Condensed Consolidated Statement of Cash Flows for the six months ended June 30, 2017 have not been restated to reflect the adoption of ASU 2014-09 and reflect our revenue policies in place at that time, as disclosed in Note 2.l. to Notes to Consolidated Financial Statements included in our Annual Report.

Storage rental and service revenues are recognized in the month the respective storage rental or service is provided, and customers are generally billed on a monthly basis on contractually agreed-upon terms. The performance obligation is a series of distinct services (as determined for purposes of ASU 2014-09, a “series”) that have the same pattern of transfer to the customer that is satisfied over time. 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 are applying the "right to invoice" practical expedient to all revenues, with the exception of storage revenues in our data center business.

(2) Summary of Significant Accounting Policies (Continued)

For all of our businesses, with the exception of the storage component of our data center business, 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, which is consistent with the practical expedient above. Our data center business features storage rental provided to the customer at contractually specified rates over a fixed contractual period. The storage rental revenue related to the storage component of our data center business is recognized on a straight-line basis over the contract term. The revenue related to the service component of our data center business is recognized in the period the data center access or related services are provided. Total data center revenues represent approximately 5% of our total consolidated revenues for the six months ended June 30, 2018.

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)

Prior to the adoption of ASU 2014-09, intake costs incurred but not charged to a customer to transport records to our facilities (or Free Move Costs, as described in Note 2.b.), which include labor and transportation costs, were capitalized and amortized as a component of depreciation and amortization in our Consolidated Statements of Operations. The initial movement of customer records into physical storage must take place prior to initiation of the storage of records and is not considered a separate performance obligation and, therefore, the costs of the initial intake of customer records into physical storage (“Intake Costs”) represent a contract fulfillment cost for the storage of records as the earnings process does not commence until a customer’s records or other assets are in our possession. Accordingly, upon the adoption of ASU 2014-09, all Intake Costs, regardless of whether or not the services associated with such initial moves are billed to the customer or are provided to the customer at no charge, will be 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. Similarly, in instances where such Intake Costs are billed to the customer, the associated revenue will be deferred and recognized over the same three year period.

Commissions

Prior to the adoption of ASU 2014-09, commissions we paid related to our long-term storage contracts were expensed as incurred. Upon the adoption of ASU 2014-09, 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.

The Contract Fulfillment Costs recorded as a result of the adoption of ASU 2014-09 as of January 1, 2018 and June 30, 2018 are as follows:



		January 1, 2018 (Date of Adoption of ASU 2014-09)							June 30, 2018
Description	Location in Balance Sheet	Gross Carrying Amount		Accumulated Amortization			Net Carrying Amount		Gross Carrying Amount		Accumulated Amortization			Net Carrying Amount
Commissions asset	Other (within Other Assets, Net)	$	42,072	$	(21,173	)	$	20,899	$	48,833	$	(28,355	)	$	20,478

d. 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"). There have been no significant changes to our accounting policies, assumptions and valuation methodologies related to the accounting for our Employee Stock-Based Awards as disclosed in Note 2.n. to Notes to Consolidated Financial Statements included in our Annual Report.

Stock-based compensation expense for Employee Stock-Based Awards for the three and six months ended June 30, 2017 was $8,543 ($5,945 after tax or $0.02 per basic and diluted share) and $15,092 ($10,530 after tax or $0.04 per basic and diluted share), respectively. Stock-based compensation expense for Employee Stock-Based Awards for the three and six months ended June 30, 2018 was $8,689 ($8,032 after tax or $0.03 per basic and diluted share) and $16,073 ($14,865 after tax or $0.05 per basic and diluted share), respectively. As of June 30, 2018, unrecognized compensation cost related to the unvested portion of our Employee Stock-Based Awards was $57,429 and is expected to be recognized over a weighted-average period of 2.2 years.

Performance Units

Under our various equity compensation plans, we may also make awards of PUs. For the majority of outstanding PUs, the number of PUs earned is determined based on our performance against predefined targets of revenue and return on invested capital ("ROIC") and, beginning with PUs granted in 2018, Adjusted EBITDA (as defined in Note 7). The number of PUs earned may range from 0% to 200% of the initial award. The number of PUs earned is determined based on our actual performance as compared to the targets at the end of a three-year performance period. Certain PUs that we grant will be earned based on a market condition associated with the total return on our common stock in relation to either (i) a subset of the Standard & Poor's 500 Index (for certain PUs granted prior to 2017), or (ii) the MSCI United States REIT Index (for certain PUs granted in 2017 and thereafter), rather than the revenue, ROIC and Adjusted EBITDA targets noted above. The number of PUs earned based on the applicable market condition may range from 0% to 200% of the initial award.

The majority of our PUs are earned based on our performance against revenue, ROIC and, beginning with PUs granted in 2018, Adjusted EBITDA targets during their applicable performance period; therefore, we forecast the likelihood of achieving the predefined revenue, ROIC and Adjusted EBITDA targets 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 revenue, ROIC and Adjusted EBITDA 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 June 30, 2018, we expected 85%, 100% and 100% achievement of the predefined revenue, ROIC and Adjusted EBITDA targets associated with the awards of PUs made in 2016, 2017 and 2018, respectively.

The fair value of earned PUs that vested during the three and six months ended June 30, 2017 and 2018 is as follows:

e. Income (Loss) Per Share—Basic and Diluted

Basic income (loss) per common share is calculated by dividing income (loss) by the weighted average number of common shares outstanding. The calculation of diluted income (loss) per share is consistent with that of basic income (loss) per share but gives effect to all potential common shares (that is, securities such as stock options, RSUs or PUs) that were outstanding during the period, unless the effect is antidilutive.

The calculation of basic and diluted income (loss) per share for the three and six months ended June 30, 2017 and 2018 is as follows:



	Three Months Ended June 30,						Six Months Ended June 30,
	2017			2018			2017			2018
Income (loss) from continuing operations	$	83,148		$	93,903		$	141,992		$	139,517

Income (loss) from continuing operations (utilized in numerator of Earnings Per Share calculation)	$	80,656		$	93,761		$	139,118		$	138,907
(Loss) income from discontinued operations, net of tax	$	(2,026	)	$	(360	)	$	(2,363	)	$	(822	)
Net income (loss) attributable to Iron Mountain Incorporated	$	78,630		$	93,401		$	136,755		$	138,085

Weighted-average shares—basic	264,217,000			285,984,000			264,036,000			285,622,000
Effect of dilutive potential stock options	395,044			237,708			428,403			243,636
Effect of dilutive potential RSUs and PUs	318,375			347,543			405,640			415,929
Weighted-average shares—diluted	264,930,419			286,569,251			264,870,043			286,281,565

f. Income Taxes

We provide for income taxes during interim periods based on our estimate of the effective tax rate for the year. Our estimate of the effective tax rate for the year ending December 31, 2018 reflects the impact of the Tax Reform Legislation (as defined below). Discrete items and changes in our estimate of the annual effective tax rate are recorded in the period they occur. Our effective tax rate is subject to variability in the future due to, among other items: (1) changes in the mix of income between our qualified REIT subsidiaries ("QRSs") and our domestic taxable REIT subsidiaries ("TRSs"), as well as among the jurisdictions in which we operate; (2) tax law changes; (3) volatility in foreign exchange gains and losses; (4) the timing of the establishment and reversal of tax reserves; and (5) our ability to utilize net operating losses that we generate.

Our effective tax rates for the three and six months ended June 30, 2017 were 18.1% and 16.2%, respectively. The primary reconciling items between the then current federal statutory tax rate of 35.0% and our overall effective tax rate for the three months ended June 30, 2017 were the benefit derived from the dividends paid deduction and differences in the rates of tax at which our foreign earnings are subject. The primary reconciling items between the then current federal statutory tax rate of 35.0% and our overall effective tax rate for the six months ended June 30, 2017 were the benefit derived from the dividends paid deduction, differences in the rates of tax at which our foreign earnings are subject and a release of valuation allowances on certain of our foreign net operating losses of $7,511 as a result of the merger of certain of our foreign subsidiaries. Our effective tax rates for the three and six months ended June 30, 2018 were 21.9% and 16.5%, respectively. The primary reconciling items between the current federal statutory tax rate of 21.0% and our overall effective tax rate for the three months ended June 30, 2018 were the benefit derived from the dividends paid deduction and the impact of differences in the tax rates at which our foreign earnings are subject, including foreign exchange gains and losses in different jurisdictions with different tax rates. The primary reconciling items between the current federal statutory tax rate of 21.0% and our overall effective tax rate for the six months ended June 30, 2018 were the benefit derived from the dividends paid deduction, a discrete tax benefit of approximately $14,000 associated with the resolution of a tax matter (as disclosed in Note 7 to Notes to Consolidated Financial Statements included in our Annual Report), and the impact of differences in the tax rates at which our foreign earnings are subject, including foreign exchange gains and losses in different jurisdictions with different tax rates.

On December 22, 2017, legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Reform Legislation”) was enacted into law in the United States. The Tax Reform Legislation amends the Internal Revenue Code of 1986, as amended (the “Code”), to reduce tax rates and modify policies, credits and deductions for businesses and individuals. The components of the Tax Reform Legislation are described in detail in Note 7 to Notes to Consolidated Financial Statements included in our Annual Report. One of the primary components of the Tax Reform Legislation was a reduction in the United States corporate federal income tax rate from 35.0% to 21.0% for taxable years beginning after December 31, 2017.

The Tax Reform Legislation also imposes a transition tax (the “Deemed Repatriation Transition Tax”) on a mandatory deemed repatriation of post-1986 undistributed foreign earnings and profits not previously subject to United States tax as of November 2, 2017 or December 31, 2017, whichever is greater (the “Undistributed E&P”), as of the last taxable year beginning before January 1, 2018. The Deemed Repatriation Transition Tax varies depending on whether the Undistributed E&P is held in liquid (as defined in the Tax Reform Legislation) or non-liquid assets. A participation deduction against the deemed repatriation will result in a Deemed Repatriation Transition Tax on Undistributed E&P of 15.5% if held in cash and liquid assets and 8.0% if held in non-liquid assets. The Deemed Repatriation Transition Tax applies regardless of whether or not an entity has cash in its foreign subsidiaries and regardless of whether the entity actually repatriates the Undistributed E&P back to the United States.

Our estimate of the amount of Undistributed E&P deemed repatriated under the Tax Reform Legislation in our taxable year ending December 31, 2017 is approximately $186,000 (the “Estimated Undistributed E&P”). We will opt to include the full amount of Estimated Undistributed E&P in our 2017 taxable income, rather than spread it over eight years (as permitted by the Tax Reform Legislation). Accordingly, included in our REIT taxable income for 2017 was approximately $82,000 related to the deemed repatriation of Undistributed E&P (the “Deemed Repatriation Taxable Income”).

(2) Summary of Significant Accounting Policies (Continued)

The Estimated Undistributed E&P includes certain assumptions made by us regarding the cumulative earnings and profits of our foreign subsidiaries, as well as the characterization of such Estimated Undistributed E&P (liquid versus non-liquid assets). We are currently performing additional analysis to determine the actual amount of Undistributed E&P associated with our foreign subsidiaries, as well as the characterization of such Undistributed E&P, and anticipate this analysis will continue until we file our 2017 United States federal income tax return. We do not believe this will have an impact on our provision for income taxes or our qualification as a REIT. However, it may impact our shareholder dividend reporting.

g. Fair Value Measurements

Our financial assets or liabilities that are carried at fair value are required to be measured using inputs from the three levels of the fair value hierarchy. A financial asset or liability's classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.

The three levels of the fair value hierarchy are as follows:

Level 1—Inputs are unadjusted quoted prices in active markets for identical assets or liabilities that we have the ability to access at the measurement date.

Level 2—Inputs include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (i.e., interest rates, yield curves, etc.), and inputs that are derived principally from or corroborated by observable market data by correlation or other means (market corroborated inputs).

Level 3—Unobservable inputs that reflect our assumptions about the assumptions that market participants would use in pricing the asset or liability.

_______________________________________________________________________________


(1)	Money market funds and time deposits are measured based on quoted prices for similar assets and/or subsequent transactions. At December 31, 2017, we had money market funds with 12 "Triple A" rated money market funds and time deposits with seven global banks. At June 30, 2018, we had no money market funds and time deposits with seven global banks.


(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 relate to short-term (six months or less) foreign currency contracts that we have entered into to hedge certain of our foreign exchange intercompany exposures, as more fully disclosed in Note 3. We calculate the value of such forward contracts by adjusting the spot rate utilized at the balance sheet date for translation purposes by an estimate of the forward points observed in active markets.


(5)	We have entered into interest rate swap agreements to hedge certain of our interest rate exposures, as more fully disclosed in Note 3. The interest rate swap agreements are designated as cash flow hedges and are measured based on inputs other than quoted market prices that are observable.

j. New Accounting Pronouncements

Recently Adopted Accounting Pronouncements

In May 2014, the FASB issued ASU 2014-09. We adopted ASU 2014-09 on January 1, 2018 using the modified retrospective method. See Note 2.c. for information regarding the impact of the adoption of ASU 2014-09 on our consolidated financial statements.

In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities ("ASU 2016-01"). ASU 2016-01 requires that most equity investments be measured at fair value, with subsequent changes in fair value recognized in net income, while eliminating the available-for-sale classification for equity securities with readily determinable fair values and the cost method for equity investments without readily determinable fair values. ASU 2016-01 also impacts financial liabilities under the fair value option and the presentation and disclosure requirements for financial instruments. We adopted ASU 2016-01 on January 1, 2018. ASU 2016-01 did not have an impact on our consolidated financial statements.

In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities ("ASU 2017-12"). ASU 2017-12 amends the hedge accounting recognition and presentation requirements as outlined in Accounting Standards Codification Topic 815 with the objective of improving the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements and enhance the transparency and understandability of hedge transactions. In addition, ASU 2017-12 simplifies the application of the hedge accounting guidance. We adopted ASU 2017-12 on January 1, 2018. ASU 2017-12 did not have a material impact on our consolidated financial statements.

Other As Yet Adopted Accounting Pronouncements

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) ("ASU 2016-02"). ASU 2016-02 will require lessees to recognize assets and liabilities on the balance sheet for the rights and obligations created by all leases with terms of more than 12 months. ASU 2016-02 also will require certain qualitative and quantitative disclosures designed to give financial statement users information on the amount, timing, and uncertainty of cash flows arising from leases. ASU 2016-02 will be effective for us on January 1, 2019. We have established a cross functional project team responsible for the assessment and implementation of ASU 2016-02. We have also entered into an agreement for the use of a lease accounting software solution that will support us in meeting the accounting and reporting requirements specific to ASU 2016-02. We are currently evaluating the impact ASU 2016-02 will have on our consolidated financial statements.

(3) Derivative Instruments and Hedging Activities

Historically, we have entered into forward contracts to hedge our exposures associated with certain foreign currencies. As of December 31, 2017, we had outstanding forward contracts to (i) purchase 138,823 United States dollars and sell 176,000 Canadian dollars, (ii) purchase 135,000 Euros and sell 160,757 United States dollars and (iii) purchase 114,390 United States dollars and sell 96,150 Euros to hedge our foreign exchange exposures. As of June 30, 2018, we had outstanding forward contracts to (i) purchase 93,000 Euros and sell 112,315 United States dollars and (ii) purchase 68,015 United States dollars and sell 58,000 Euros to hedge our foreign exchange exposures. We have not designated any of the forward contracts we have entered into as hedges.

Net cash receipts (payments) included in cash from operating activities related to settlements associated with foreign currency forward contracts for the three and six months ended June 30, 2017 and 2018 are as follows:



	Three Months Ended June 30,					Six Months Ended June 30,
	2017		2018			2017		2018
Net cash receipts (payments)	$	893	$	(7,554	)	$	893	$	(1,211	)

Our policy is to record the fair value of each derivative instrument on a gross basis. The following table provides the fair value of our derivative instruments not designated as hedging instruments as of December 31, 2017 and June 30, 2018:



Derivatives Not Designated as Hedging Instruments	Balance Sheet Location	December 31, 2017		June 30, 2018
Derivative assets	Prepaid expenses and other	$	1,579	$	318
Derivative liabilities	Accrued expenses	2,329		3,413

(Gains) losses for our derivative instruments not recognized as hedging instruments for the three and six months ended June 30, 2017 and 2018 are as follows:



		Three Months Ended June 30,				Six Months Ended June 30,
Derivatives Not Designated as Hedging Instruments	Location of Loss (Gain) Recognized in Income on Derivative	2017		2018		2017		2018
Foreign exchange contracts	Other (income) expense, net	$	—	$	9,547	$	—	$	3,556

We have designated a portion of our (i) Euro denominated borrowings by IMI under our Former Revolving Credit Facility and (ii) Euro Notes as a hedge of net investment of certain of our Euro denominated subsidiaries. For the six months ended June 30, 2017, we designated, on average, 73,175 Euros of our Euro denominated borrowings by IMI under our Former Revolving Credit Facility as a hedge of net investment of certain of our Euro denominated subsidiaries. For the six months ended June 30, 2018, we designated, on average, 179,881 Euros 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, which is a component of accumulated other comprehensive items, net:



	Three Months Ended June 30,					Six Months Ended June 30,
	2017			2018		2017			2018
Foreign exchange (losses) gains	$	(7,076	)	$	10,257	$	(8,148	)	$	4,622

As of June 30, 2018, cumulative net gains of $7,810, net of tax, are recorded in accumulated other comprehensive items, net associated with this net investment hedge.

(3) Derivative Instruments and Hedging Activities (Continued)

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 June 30, 2018, we have $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 rate payments (at the fixed rate interest specified in the interest rate swap agreements). We have designated these interest rate swaps as cash flow hedges. Unrealized gains are recognized as assets while unrealized losses are recognized as liabilities. The fair value of the interest rate swaps are estimated using industry standard valuation models using market-based observable inputs, including interest rate curves (Level 2, as described in Note 2.g.). At June 30, 2018, we had a derivative asset of $2,203, which was recorded as a component of Other within Other assets, net in our Condensed Consolidated Balance Sheet, which represents the fair value of our interest rate swap agreements.

We have recorded the change in fair value of the interest rate swap agreements to accumulated other comprehensive income. We have recorded unrealized gains of $2,388 and $2,203 for the three and six months ended June 30, 2018, respectively, associated with our interest rate swap agreements. At June 30, 2018, we have recorded cumulative unrealized gains of $2,203 within accumulated other comprehensive items, net associated with these agreements.

(4) 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. Acquisition of IO Data Centers

On January 10, 2018, we completed the acquisition of the United States operations of IODC, a leading data center colocation space and solutions provider based in Phoenix, Arizona, including the land and buildings associated with four data centers in Phoenix and Scottsdale, Arizona; Edison, New Jersey; and Columbus, Ohio (the “IODC Transaction”). At the closing of the IODC Transaction, we paid approximately $1,347,000. In addition to the amount paid at the closing of the IODC Transaction, there is the potential of $35,000 in additional payments associated with the execution of future customer contracts. We have accounted for the IODC Transaction as an acquisition of a business in accordance with the guidance in ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business.

The unaudited consolidated pro forma financial information (the "Pro Forma Financial Information") below summarizes the combined results of us and IODC on a pro forma basis as if the IODC Transaction had occurred on January 1, 2017. The Pro Forma Financial Information is presented for informational purposes and is not necessarily indicative of the results of operations that would have been achieved if the acquisition had taken place on January 1, 2017. The Pro Forma Financial Information, for all periods presented, includes our current estimates of purchase accounting adjustments (including amortization expenses from acquired intangible assets and depreciation of acquired property, plant and equipment). We and IODC have collectively incurred $28,064 of operating expenditures to complete the IODC Transaction (including advisory and professional fees). These operating expenditures have been reflected within the results of operations in the Pro Forma Financial Information as if they were incurred on January 1, 2017.



	Three Months Ended June 30,				Six Months Ended June 30,
	2017		2018		2017		2018
Total Revenues	$	983,723	$	1,060,823	$	1,957,480	$	2,106,752

In addition to our acquisition of IODC, we completed certain other acquisitions during 2017 and 2018. The Pro Forma Financial Information does not reflect these acquisitions due to the insignificant impact of these acquisitions on our consolidated results of operations.

b. Other Noteworthy Acquisitions

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.

(4) Acquisitions (Continued)

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. (collectively, "EvoSwitch"), a leading 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.

In November 2017, we entered into an agreement to acquire (i) the storage and information management assets and operations of Santa Fe Group A/S ("Santa Fe") in China (the “Santa Fe China Transaction”) for approximately 14,000 Euros and (ii) certain real estate property located in Beijing, China owned by Santa Fe (the “Beijing Property”) for approximately 9,000 Euros, representing a total purchase price of approximately 23,000 Euros, subject to customary purchase price adjustments. We closed on the Santa Fe China Transaction on December 29, 2017. The purchase price for the Santa Fe China Transaction was not paid until January 2018 and, therefore, we accrued for the purchase price of the Santa Fe China Transaction (which was approximately $16,800, based upon the exchange rate between the Euro and the United States dollar on the closing date of the Santa Fe China Transaction) in our Consolidated Balance Sheet as of December 31, 2017 (the “Accrued Purchase Price”). The Accrued Purchase Price is presented as a component of the current portion of long-term debt in our Consolidated Balance Sheet as of December 31, 2017. We paid the purchase price of the Santa Fe China Transaction on January 3, 2018. We expect to close on the acquisition of the Beijing Property during the second half of 2018. The completion of the acquisition of the Beijing Property is subject to closing conditions; accordingly, we can provide no assurances that we will be able to complete the acquisition of the Beijing Property, that it will not be delayed or that the terms will remain the same.

A summary of the cumulative consideration paid and the preliminary allocation of the purchase price paid for all of our 2018 acquisitions through June 30, 2018 is as follows:

(4) Acquisitions (Continued)

(1)

Included in cash paid for acquisitions in the Condensed Consolidated Statement of Cash Flows for the six months ended June 30, 2018 is net cash acquired of $34,711 and contingent and other payments, net of $7,177 related to acquisitions made in previous years. The cash paid for the Accrued Purchase Price for the Santa Fe China Transaction is included in cash flows from financing activities (as a component of repayment of revolving credit, term loan and bridge facilities and other debt) in the Condensed Consolidated Statement of Cash Flows for the six months ended June 30, 2018.


(2)	Consists primarily of building, building improvements, leasehold improvements, data center infrastructure, racking structures and warehouse equipment. These assets are depreciated using the straight-line method with the useful lives as noted in Note 2.g. to Notes to Consolidated Financial Statements included in our Annual Report.

(3) The goodwill associated with acquisitions is primarily attributable to the assembled workforce, expanded market opportunities and costs and other operating synergies anticipated upon the integration of the operations of us and the acquired businesses.

See Note 6 to Notes to Consolidated Financial Statements included in our Annual Report for additional information regarding our allocations of the purchase price for acquisitions. The preliminary purchase price allocations that are not finalized as of June 30, 2018 primarily relate to the final assessment of the fair values of intangible assets (primarily customer relationship intangible assets and data center lease-based intangible assets), property, plant and equipment (primarily building, building improvements, data center infrastructure and racking structures), operating leases, contingencies and income taxes (primarily deferred income taxes), primarily associated with the Bonded Transaction, the Santa Fe Transaction, the Fortrust Transaction (each as defined in Note 6 to Notes to Consolidated Financial Statements included in our Annual Report), the IODC Transaction, the Credit Suisse Transaction and the EvoSwitch Transaction, as well as other acquisitions we closed in 2018.

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 six months ended June 30, 2018 were not material to our results from operations.

(5) Debt (Continued)

a. Credit Agreement Amendments

On March 22, 2018, we entered into an amendment (the “2018 First Amendment”) to the Credit Agreement which provided us with the option to request additional commitments of up to $1,260,000 under the Credit Agreement in the form of term loans or through increased commitments under the Revolving Credit Facility, subject to the conditions specified in the Credit Agreement. On June 4, 2018, we entered into another amendment (the "2018 Second Amendment") to the Credit Agreement which (i) reduced interest rate margins applicable to existing and future borrowings under the Revolving Credit Facility and Term Loan A by 0.25% and (ii) extended the maturity date of the Credit Agreement to June 4, 2023.

In connection with the 2018 First Amendment, Iron Mountain Information Management, LLC ("IMIM") entered into an incremental term loan activation notice, or the Activation Notice, with certain lenders pursuant to which the lenders party to the Activation Notice agreed to provide commitments to fund an incremental term loan B in the amount of $700,000 (the “Term Loan B”). On March 26, 2018, IMIM borrowed the full amount of the Term Loan B, which matures on January 2, 2026. The Term Loan B was issued at 99.75% of par. The aggregate net proceeds of approximately $689,850, after paying commissions to the joint lead arrangers and net of the original discount, were used to repay outstanding borrowings under the Revolving Credit Facility. 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 after September 22, 2018. The Term Loan B bears interest at a rate of LIBOR plus 1.75%.

b. Australian Dollar Term Loan Amendment

On March 27, 2018, Iron Mountain Australia Group Pty Ltd, a wholly owned subsidiary of IMI, amended its AUD Term Loan (the "AUD Term Loan Amendment") to (i) increase the borrowings under the AUD Term Loan from 250,000 Australian dollars to 350,000 Australian dollars; (ii) increase the quarterly principal payments from 6,250 Australian dollars per year to 8,750 Australian dollars per year and (iii) decrease the interest rate on the AUD Term Loan from BBSY (an Australian benchmark variable interest rate) plus 4.3% to BBSY plus 3.875%. The AUD Term Loan matures in September 2022. All indebtedness associated with the AUD Term Loan was issued at 99% of par. The net proceeds associated with the AUD Term Loan Amendment of approximately 99,000 Australian dollars (or approximately $75,621, based on the exchange rate between the Australian dollar and the United States dollar on March 29, 2018 (the closing date of the AUD Term Loan Amendment)), net of the original discount, were used to repay outstanding borrowings under the Revolving Credit Facility.

Principal payments on the AUD Term Loan are to be paid in quarterly installments in an amount equivalent to an aggregate of 8,750 Australian dollars per year, with the remaining balance due September 22, 2022. The AUD Term Loan is secured by substantially all assets of Iron Mountain Australia Group Pty. Ltd. IMI and its direct and indirect 100% owned United States subsidiaries that represent the substantial majority of its United States operations (the “Guarantors”) guarantee all obligations under the AUD Term Loan.

c. Cash Pooling

As described in greater detail in Note 4 to Notes to Consolidated Financial Statements included in our Annual Report, certain of our subsidiaries participate in cash pooling arrangements (the “Cash Pools”) with Bank Mendes Gans (“BMG”), an independently operated fully-owned subsidiary of ING Group, in order to help manage global liquidity requirements. We currently utilize two separate cash pools with BMG, one of which we utilize to manage global liquidity requirements for our QRSs (the "QRS Cash Pool") and the other for our TRSs (the "TRS Cash Pool").

(5) Debt (Continued)

As of December 31, 2017, we had a net cash position of approximately $5,700 in the QRS Cash Pool (which consisted of a gross cash position of approximately $383,700 less outstanding debit balances of approximately $378,000 by participating subsidiaries) and we had a zero balance in the TRS Cash Pool (which consisted of a gross cash position of approximately $229,600 less outstanding debit balances of approximately $229,600 by participating subsidiaries). As of June 30, 2018, we had a net cash position of approximately $2,000 in the QRS Cash Pool (which consisted of a gross cash position of approximately $406,900 less outstanding debit balances of approximately $404,900 by participating subsidiaries) and we had a net cash position of approximately $600 in the TRS Cash Pool (which consisted of a gross cash position of approximately $262,800 less outstanding debit balances of approximately $262,200 by participating subsidiaries). The net cash position balances as of December 31, 2017 and June 30, 2018 are reflected as cash and cash equivalents in the Condensed Consolidated Balance Sheets.

d. Debt Covenants

The Credit Agreement, our 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 indentures or other agreements governing our indebtedness. The Credit Agreement uses EBITDAR-based calculations as the primary measures of financial performance, including leverage and fixed charge coverage ratios.

Our leverage and fixed charge coverage ratios under the Credit Agreement as of December 31, 2017 and June 30, 2018, as well as our leverage ratio under our indentures as of December 31, 2017 and June 30, 2018 are as follows:



	December 31, 2017	June 30, 2018	Maximum/Minimum Allowable
Net total lease adjusted leverage ratio	5.0	5.6	Maximum allowable of 6.5
Net secured debt lease adjusted leverage ratio	1.6	2.5	Maximum allowable of 4.0
Bond leverage ratio (not lease adjusted)	5.8	5.7	Maximum allowable of 6.5-7.0(1)(2)
Fixed charge coverage ratio	2.1	2.3	Minimum allowable of 1.5

______________________________________________________________

(1)

The maximum allowable leverage ratio under our indentures for the 4⁷/₈% Notes, the GBP Notes due 2025 and the 5¹/₄% Notes is 7.0, while the maximum allowable leverage ratio under the indentures pertaining to our remaining senior and senior subordinated notes is 6.5. In certain instances as provided in our indentures, we have the ability to incur additional indebtedness that would result in our bond leverage ratio exceeding the maximum allowable ratio under our indentures and still remain in compliance with the covenant.

(2)

At December 31, 2017, a portion of the net proceeds from the 5¹/₄% Notes, together with a portion of the net proceeds of the Equity Offering (as defined in Note 9), were used to temporarily repay approximately $807,000 of outstanding indebtedness under our Revolving Credit Facility until the closing of the IODC Transaction, which occurred on January 10, 2018. The bond leverage ratio at December 31, 2017 is calculated based on our outstanding indebtedness at this date, which reflects the temporary payment of the Revolving Credit Facility.

Noncompliance with these leverage and fixed charge coverage ratios would have a material adverse effect on our financial condition and liquidity.

(6) Selected Consolidated Financial Statements of Parent, Guarantors, Canada Company and Non-Guarantors

The following data summarizes the consolidating results of IMI on the equity method of accounting as of December 31, 2017 and June 30, 2018 and for the three and six months ended June 30, 2017 and 2018 and are prepared on the same basis as the consolidated financial statements.

The Parent Notes, the CAD Notes, the 6¹/₈% GBP Senior Notes due 2022 (the "GBP Notes due 2022") (which were redeemed in November 2017), the GBP Notes due 2025, and the 5³/₈% Notes are guaranteed by the subsidiaries referred to below as the Guarantors. These subsidiaries are 100% owned by IMI. The guarantees are full and unconditional, as well as joint and several.

Additionally, IMI guarantees the CAD Notes, which were issued by Iron Mountain Canada Operations ULC ("Canada Company"), the GBP Notes due 2022, which were issued by Iron Mountain Europe PLC ("IME"), the GBP Notes due 2025, which were issued by Iron Mountain (UK) PLC ("IM UK"), and the 5³/₈% Notes, which were issued by Iron Mountain US Holdings, Inc, which is one of the Guarantors. Canada Company, IME and IM UK do not guarantee the Parent Notes. The subsidiaries that do not guarantee the Parent Notes, the CAD Notes, the GBP Notes due 2022, the GBP Notes due 2025, and the 5³/₈% Notes, including IME, IM UK, Iron Mountain Receivables QRS, LLC, Iron Mountain Receivables TRS, LLC and Iron Mountain Mortgage Finance I, LLC, are referred to below as the Non-Guarantors. As discussed below, the results of the Non-Guarantors for the three and six months ended June 30, 2017 exclude the results of Canada Company, as those are presented in a separate column.

The CAD Notes due 2021 were issued by Canada Company and registered under the Securities Act of 1933, as amended (the “Securities Act”). The CAD Notes due 2023 have not been registered under the Securities Act, or under the securities laws of any other jurisdiction. We redeemed the CAD Notes due 2021 in August 2017 and, therefore, as of that date, Canada Company had no outstanding debt registered under the Securities Act that would require the presentation of Canada Company on a standalone basis in the accompanying consolidating financial statements. Accordingly, (i) the assets, liabilities and equity of Canada Company are presented as a component of the Non-Guarantor subsidiaries in the accompanying Condensed Consolidated Balance Sheets as of December 31, 2017 and June 30, 2018, (ii) the revenues, expenses and other comprehensive income (loss) of Canada Company are presented as a component of the Non-Guarantor subsidiaries in the Condensed Consolidated Statement of Operations and Comprehensive Income (Loss) for the three and six months ended June 30, 2018, and (iii) the operating, investing and financing cash flows for Canada Company are presented as a component of the Non-Guarantor subsidiaries in the Condensed Consolidated Statement of Cash Flows for the six months ended June 30, 2018.

In the normal course of business, we periodically change the ownership structure of our subsidiaries to meet the requirements of our business. In the event of such changes, we recast the prior period financial information within this footnote to conform to the current period presentation in the period such changes occur. Generally, these changes do not alter the designation of the underlying subsidiaries as Guarantors or Non-Guarantors. However, they may change whether the underlying subsidiary is owned by the Parent, a Guarantor or a Non-Guarantor. If such a change occurs, the amount of investment in subsidiaries in the below Condensed Consolidated Balance Sheets and equity in the earnings (losses) of subsidiaries, net of tax in the below Condensed Consolidated Statements of Operations and Comprehensive Income (Loss) with respect to the relevant Parent, Guarantors, Non-Guarantors and Eliminations columns also would change.

(7) Segment Information (Continued)

The accounting policies of the reportable segments are the same as those described in Note 2 and in our Annual Report. Adjusted EBITDA for each segment is defined as income (loss) from continuing operations before interest expense, net, provision (benefit) for income taxes, depreciation and amortization, and also excludes certain items that we believe are not indicative of our core operating results, specifically: (i) (gain) loss on disposal/write-down of property, plant and equipment (excluding real estate), net; (ii) intangible impairments; (iii) other (income) expense, net; (iv) gain on sale of real estate, net of tax; and (v) Significant Acquisition Costs (as defined below). Internally, we use Adjusted EBITDA as the basis for evaluating the performance of, and allocating resources to, our operating segments.

A reconciliation of Adjusted EBITDA to income (loss) from continuing operations on a consolidated basis is as follows:



	Three Months Ended June 30,						Six Months Ended June 30,

(8) Commitments and Contingencies

We are involved in litigation from time to time in the ordinary course of business. 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 able to be estimated. We record legal costs associated with loss contingencies as expenses in the period in which they are incurred. There have been no material updates or changes to the matters disclosed in Note 10 to Notes to Consolidated Financial Statements included in our Annual Report, nor have there been any new material loss contingencies since December 31, 2017. We continue to believe that the resolution of the matters disclosed in Note 10 to Notes to Consolidated Financial Statements included in our Annual Report will not have a material impact on our consolidated financial condition, results of operations or cash flows. We have estimated a reasonably possible range for all loss contingencies, including those disclosed in Note 10 to Notes to Consolidated Financial Statements included in our Annual Report, and believe it is reasonably possible that we could incur aggregate losses in addition to amounts currently accrued for all matters up to an additional $17,200 over the next several years, of which certain amounts would be covered by insurance or indemnity arrangements.

(9) 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 fiscal year 2017 and in the first six months of 2018, our board of directors declared the following dividends:

At The Market (ATM) Equity Program

As described in greater detail in Note 13 to Notes to Consolidated Financial Statements included in our Annual Report, we entered into a distribution agreement (the “Distribution Agreement”) with a syndicate of 10 banks (the “Agents”) pursuant to which we may sell, from time to time, up to an aggregate sales price of $500,000 of our common stock through the Agents (the “At The Market (ATM) Equity Program”). There were no shares of common stock sold under the At The Market (ATM) Equity Program during the three months ended June 30, 2018. During the six months ended June 30, 2018 under the At The Market (ATM) Equity Program, we sold an aggregate of 273,486 shares of common stock for gross proceeds of approximately $8,800, generating net proceeds of $8,716, after deducting commissions of $90. As of June 30, 2018 the remaining aggregate sale price of shares of our common stock available for distribution under the At The Market (ATM) Equity Program was approximately $431,200.

Equity Offering

On December 12, 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 (the “Firm Shares”) of our common stock (the “Equity Offering”). The offering price to the public for the Equity Offering was $37.00 per share, and we agreed to pay the Underwriters an underwriting commission of $1.38195 per share. The net proceeds to us from the Equity Offering, after deducting underwriters' commissions, was $516,462. At December 31, 2017, the net proceeds of the Equity Offering, together with the net proceeds from the 5¹/₄% Notes, were used to temporarily repay borrowings under our Revolving Credit Facility and invest in money market funds.

(9) Stockholders' Equity Matters (Continued)

Pursuant to the Underwriting Agreement, we granted the Underwriters a 30-day option to purchase from us up to an additional 2,175,000 shares of common stock (the “Option Shares”) at the public offering price, less the underwriting commission and less an amount per share equal to any dividends or distributions declared by us and payable on the Firm Shares but not payable on the Option Shares (the “Over-Allotment Option"). On January 10, 2018, the Underwriters exercised the Over-Allotment Option in its entirety. The net proceeds to us from the exercise of the Over-Allotment Option, after deducting underwriters' commissions and the per share value of the dividend we declared on our common stock on October 24, 2017 (for which the record date was December 15, 2017) which was paid on January 2, 2018, was approximately $76,200. The net proceeds of the Equity Offering and the Over-Allotment Option, together with the net proceeds from the issuance of the 5¹/₄% Notes, were used to finance the purchase price of the IODC Transaction, and to pay related fees and expenses.

(10) Divestments

a. Recall Divestments

The table below summarizes certain results of operations of the Recall Divestments (as defined in Note 14 to Notes to Consolidated Financial Statements included in our Annual Report) included in discontinued operations for the three and six months ended June 30, 2017 and 2018:



	Three Months Ended June 30,						Six Months Ended June 30,
Description	2017			2018			2017			2018
(Loss) Income from Discontinued Operations Before (Benefit) Provision for Income Taxes	$	(3,049	)	$	(477	)	$	(3,478	)	$	(973	)

(Loss) Income from Discontinued Operations, Net of Tax	$	(2,026	)	$	(360	)	$	(2,363	)	$	(822	)

On May 4, 2016, we completed the Access Sale to Access CIG (each as defined in Note 6 to Notes to Consolidated Financial Statements included in our Annual Report) for total consideration of approximately $80,000. Of the total consideration, we received $55,000 in cash proceeds at closing and we are entitled to receive up to $25,000 of additional cash proceeds (the “Access Contingent Consideration”). The Access Contingent Consideration is subject to adjustments for customer attrition subsequent to the closing of the Access Sale. We are also subject to potential indemnity obligations as part of the Access Sale.

In June 2018, Access CIG sent us a communication asserting that they did not owe any Access Contingent Consideration to us. Access CIG has also made claims for indemnification in unspecified amounts. We are currently evaluating the assertions and claims made by Access CIG, though we expect to vigorously contest certain of their assertions and claims. We have recorded a non-trade receivable related to the Access Contingent Consideration within Prepaid expenses and other in our Condensed Consolidated Balance Sheets as of December 31, 2017 and June 30, 2018 based upon our estimate of the realizable value of the Access Contingent Consideration. Any change to our estimate of the realizable value of the Access Contingent Consideration (either favorable or unfavorable) will be recorded to our Consolidated Statement of Operations as a component of discontinued operations.

b. Russia and Ukraine Divestment

On May 30, 2017, Iron Mountain EES Holdings Ltd. ("IM EES"), a consolidated subsidiary of IMI, sold its records and information management operations in Russia and Ukraine to OSG Records Management (Europe) Limited (“OSG”) in a stock transaction (the “Russia and Ukraine Divestment”). As consideration for the Russia and Ukraine Divestment, IM EES received a 25% equity interest in OSG (the "OSG Investment").

(10) Divestments (Continued)

We have concluded that the Russia and Ukraine Divestment does not meet the criteria to be reported as discontinued operations in our consolidated financial statements, as our decision to divest these businesses does not represent a strategic shift that will have a major effect on our operations and financial results. Accordingly, the revenues and expenses associated with these businesses are presented as a component of income (loss) from continuing operations in our Condensed Consolidated Statements of Operations for the three and six months ended June 30, 2017 and the cash flows associated with these businesses are presented as a component of cash flows from continuing operations in our Condensed Consolidated Statement of Cash Flows for the six months ended June 30, 2017.

As a result of the Russia and Ukraine Divestment, we recorded a gain on sale of $38,869 to other expense (income), net, during the second quarter of 2017, representing the excess of the fair value of the consideration received over the carrying value of our businesses in Russia and Ukraine. As of the closing date of the Russia and Ukraine Divestment, the fair value of the OSG Investment (as defined in Note 14 to Notes to Consolidated Financial Statements included in our Annual Report) was approximately $18,000. As of the closing date of the Russia and Ukraine Divestment, the carrying value of our businesses in Russia and Ukraine was a credit balance of $20,869, which consisted of (i) a credit balance of approximately $29,100 of cumulative translation adjustment associated with our businesses in Russia and Ukraine that was reclassified from accumulated other comprehensive items, net, (ii) the carrying value of the net assets of our businesses in Russia and Ukraine, excluding goodwill, of $4,716 and (iii) $3,515 of goodwill associated with our former Northern and Eastern Europe reporting unit (of which our businesses in Russia and Ukraine were a component of prior to the Russia and Ukraine Divestment), which was allocated, on a relative fair value basis, to our businesses in Russia and Ukraine.

We account for the OSG Investment as an equity method investment. As of December 31, 2017 and June 30, 2018, the fair value of the OSG Investment is $17,539 and $17,445, respectively and is presented as a component of Other within Other assets, net in our Consolidated Balance Sheet.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of our financial condition and results of operations for the three and six months ended June 30, 2018 should be read in conjunction with our Condensed Consolidated Financial Statements and Notes thereto for the three and six months ended June 30, 2018, included herein, and our Consolidated Financial Statements and Notes thereto for the year ended December 31, 2017, included in our Annual Report on Form 10-K filed with the United States Securities and Exchange Commission ("SEC") on February 16, 2018 (our "Annual Report").

FORWARD-LOOKING STATEMENTS

We have made statements in this Quarterly Report on Form 10-Q ("Quarterly Report") that constitute "forward-looking statements" as that term is defined in the Private Securities Litigation Reform Act of 1995 and other securities laws. These forward-looking statements concern our operations, economic performance, financial condition, goals, beliefs, future growth strategies, investment objectives, plans and current expectations, such as our (1) commitment to future dividend payments, (2) expected growth of records stored with us from existing customers, (3) expected 2018 consolidated internal storage rental revenue growth rate and capital expenditures, (4) statements made in relation (i) to our acquisition of Recall Holdings Limited ("Recall") pursuant to the Scheme Implementation Deed, as amended, with Recall (the "Recall Transaction") and (ii) our acquisition of IO Data Centers, LLC ("IODC"), including the total acquisition expenditures related to Recall and IODC and the cost to integrate Recall into our existing operations, (5) statements regarding our expectation to reduce our leverage ratio, (6) our ability to close pending acquisitions, (7) expectations regarding the impact of the recent United States tax reform legislation on our consolidated results of operations and (8) expectations regarding the impact of the adoption of ASU 2014-09 (as defined below) on our Adjusted EBITDA (as defined below) for the year ending December 31, 2018. These forward-looking statements are subject to various known and unknown risks, uncertainties and other factors. When we use words such as "believes," "expects," "anticipates," "estimates" or similar expressions, we are making forward-looking statements. Although we believe that our forward-looking statements are based on reasonable assumptions, our expected results may not be achieved, and actual results may differ materially from our expectations. In addition, important factors that could cause actual results to differ from expectations include, among others:


•	our ability to remain qualified for taxation as a real estate investment trust for United States federal income tax purposes ("REIT");


•	the adoption of alternative technologies and shifts by our customers to storage of data through non-paper based technologies;


•	changes in customer preferences and demand for our storage and information management services;


•	the cost to comply with current and future laws, regulations and customer demands relating to data security and privacy issues, as well as fire and safety standards;


•	the impact of litigation or disputes that may arise in connection with incidents in which we fail to protect our customers' information or our internal records or IT systems and the impact of such incidents on our reputation and ability to compete;


•	changes in the price for our storage and information management services relative to the cost of providing such storage and information management services;


•	changes in the political and economic environments in the countries in which our international subsidiaries operate and changes in the global political climate;


•	our ability or inability to manage growth, expand internationally, complete acquisitions on satisfactory terms, to close pending acquisitions and to integrate acquired companies efficiently;


•	changes in the amount of our growth and maintenance capital expenditures and our ability to invest according to plan;


•	our ability to comply with our existing debt obligations and restrictions in our debt instruments or to obtain additional financing to meet our working capital needs;


•	the impact of service interruptions or equipment damage and the cost of power on our data center operations;


•	changes in the cost of our debt;


•	the impact of alternative, more attractive investments on dividends;


•	the cost or potential liabilities associated with real estate necessary for our business;


•	the performance of business partners upon whom we depend for technical assistance or management expertise outside the United States; and


•	other trends in competitive or economic conditions affecting our financial condition or results of operations not presently contemplated.

Table of Contents

You should not rely upon forward-looking statements except as statements of our present intentions and of our present expectations, which may or may not occur. You should read these cautionary statements as being applicable to all forward-looking statements wherever they appear. Except as required by law, we undertake no obligation to release publicly the result of any revision to these forward-looking statements that may be made to reflect events or circumstances after the date hereof or to reflect the occurrence of unanticipated events. Readers are also urged to carefully review and consider the various disclosures we have made in this Quarterly Report, as well as our other periodic reports filed with the SEC including under "Risk Factors" in our Annual Report.

Overview

The following discussions set forth, for the periods indicated, management's discussion and analysis of financial condition and results of operations. Significant trends and changes are discussed for the three and six month periods ended June 30, 2018 within each section. Trends and changes that are consistent with the three and six month periods are not repeated and are discussed on a year to date basis only.

Adoption of ASU 2014-09

In May 2014, the Financial Accounting Standards Board issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU 2014-09"), which is described in greater detail in Note 2.c. to Notes to Condensed Consolidated Financial Statements included in this Quarterly Report. We adopted ASU 2014-09 as of January 1, 2018 using the modified retrospective method, whereby the cumulative effect of applying ASU 2014-09 is recognized at the date of initial application. As a result, the comparative Condensed Consolidated Balance Sheet as of December 31, 2017, the Condensed Consolidated Statements of Operations and the Condensed Consolidated Statements of Comprehensive Income (Loss) for the three and six months ended June 30, 2017 and the Condensed Consolidated Statement of Equity and the Condensed Consolidated Statement of Cash Flows for the six months ended June 30, 2017 have not been restated to reflect the adoption of ASU 2014-09.

As a result of the adoption of ASU 2014-09, Adjusted EBITDA for the three and six months ended June 30, 2018 increased by approximately $8.0 million and $12.0 million, respectively, compared to the prior year periods. The adoption of ASU 2014-09 did not have a material impact on Adjusted EPS, FFO (Nareit) or FFO (Normalized) (each as defined below) for the three and six months ended June 30, 2018 compared to the prior year periods. The revenues for the three and six months ended June 30, 2018 reflect a net $3.1 million and $6.6 million, respectively, reclassification of certain components of storage rental revenues to service revenues associated with the adoption of ASU 2014-09. We expect our Adjusted EBITDA for the year ending December 31, 2018 to increase by approximately $20.0 million to $25.0 million as a result of the adoption of ASU 2014-09.

Significant Acquisitions

a. Recall Acquisition

On May 2, 2016, we completed the Recall Transaction. The results of operations of Recall have been included in our consolidated results from May 2, 2016. See Note 6 to Notes to Consolidated Financial Statements included in our Annual Report for additional information.

b. IODC Acquisition

On January 10, 2018, we completed the acquisition of the United States operations of IODC, a leading data center colocation space and solutions provider based in Phoenix, Arizona, including the land and buildings associated with four data centers in Phoenix and Scottsdale, Arizona; Edison, New Jersey; and Columbus, Ohio (the "IODC Transaction"). At the closing of the IODC Transaction, we paid approximately $1,347.0 million. In addition to the amount paid at the closing of the IODC Transaction, there is the potential of $35.0 million in additional payments associated with the execution of future customer contracts.

Table of Contents

Significant Acquisition Costs

We currently estimate total acquisition and integration expenditures associated with the Recall Transaction and acquisition expenditures associated with the IODC Transaction to be approximately $395.0 million, the majority of which is expected to be incurred by the end of 2018. This amount consists of operating expenditures associated with (1) the Recall Transaction, including: (i) advisory and professional fees to complete the Recall Transaction; (ii) costs associated with the Divestments (as defined in Note 14 to Notes to Consolidated Financial Statements included in our Annual Report) required in connection with receipt of regulatory approvals (including transitional services); and (iii) costs to integrate Recall with our existing operations, including moving, severance, facility upgrade, REIT conversion and system upgrade costs, as well as certain costs associated with our shared service center initiative for our finance, human resources and information technology functions; and (2) the advisory and professional fees to complete the IODC Transaction (collectively, "Significant Acquisition Costs"). From January 1, 2015 through June 30, 2018, we have incurred cumulative operating and capital expenditures associated with the Recall Transaction and the IODC Transaction of $350.4 million, including $293.3 million of Significant Acquisition Costs and $57.1 million of capital expenditures.

See Note 11 to Notes to Condensed Consolidated Financial Statements included in this Quarterly Report for more information on Significant Acquisition Costs, including costs recorded by segment as well as recorded between cost of sales and selling, general and administrative expenses.

Divestments

On May 30, 2017, as disclosed in Note 10 to Notes to Condensed Consolidated Financial Statements included in this Quarterly Report, Iron Mountain EES Holdings Ltd. ("IM EES"), a consolidated subsidiary of ours, sold its records and information management operations in Russia and Ukraine to OSG Records Management (Europe) Limited (“OSG”) in a stock transaction in exchange for a 25% equity interest in OSG (the “Russia and Ukraine Divestment”). As described in Note 10 to Notes to Condensed Consolidated Financial Statements included in this Quarterly Report, the Russia and Ukraine Divestment did not meet the criteria to be reported as discontinued operations in our consolidated financial statements. The Russia and Ukraine Divestment represents approximately $3.4 million and $8.6 million of total revenues and approximately $(1.3) million and $0.9 million of total (loss) income from continuing operations for the three and six months ended June 30, 2017, respectively.

General

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, technology escrow services that protect and manage source code, data backup and storage on our proprietary cloud 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 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 related sale of recycled paper, the price of which can fluctuate from period to period, and customer termination and permanent removal fees; (3) other services, including the scanning, imaging and document conversion services of active and inactive records and project revenues; (4) consulting services; and (5) cloud-related data protection, preservation, restoration and recovery.

Cost of sales (excluding depreciation and amortization) consists primarily of wages and benefits for field personnel, facility occupancy costs (including rent and utilities), transportation expenses (including vehicle leases and fuel), other product cost of sales and other equipment costs and supplies. Of these, wages and benefits and facility occupancy costs are the most significant. Selling, general and administrative expenses consist primarily of wages and benefits for management, administrative, information technology, sales, account management and marketing personnel, as well as expenses related to communications and data processing, travel, professional fees, bad debts, training, office equipment and supplies.

The expansion of our international businesses has impacted the major cost of sales components and selling, general and administrative expenses. Our international operations are more labor intensive relative to revenue than our operations in North America and, therefore, labor costs are a higher percentage of international segment revenue. In addition, the overhead structure of our expanding international operations has generally not achieved the same level of overhead leverage as our North American segments, which may result in an increase in selling, general and administrative expenses as a percentage of consolidated revenue as our international operations become a more meaningful percentage of our consolidated results.

Table of Contents

Our consolidated revenues and expenses are subject to the net effect of foreign currency translation related to our entities outside the United States. It is difficult to predict the future fluctuations of foreign currency exchange rates and how those fluctuations will impact our Consolidated Statements of Operations. As a result of the relative size of our international operations, these fluctuations may be material on individual balances. Our revenues and expenses from our international operations are generally denominated in the local currency of the country in which they are derived or incurred. Therefore, the impact of currency fluctuations on our operating income and operating margin is partially mitigated. In order to provide a framework for assessing how our underlying businesses performed excluding the effect of foreign currency fluctuations, we compare the percentage change in the results from one period to another period in this report using constant currency presentation. The constant currency growth rates are calculated by translating the 2017 results at the 2018 average exchange rates. Constant currency growth rates are a non-GAAP measure.

The following table is a comparison of underlying average exchange rates of the foreign currencies that had the most significant impact on our United States dollar-reported revenues and expenses:



	Average Exchange Rates for the Three Months Ended June 30,				Percentage Strengthening / (Weakening) of Foreign Currency
	2017		2018		Percentage Strengthening / (Weakening) of Foreign Currency
Australian dollar	$	0.751	$	0.757	0.8	%

Non-GAAP Measures

Adjusted EBITDA

Adjusted EBITDA is defined as income (loss) from continuing operations before interest expense, net, provision (benefit) for income taxes, depreciation and amortization, and also excludes certain items that we believe are not indicative of our core operating results, specifically: (i) (gain) loss on disposal/write-down of property, plant and equipment (excluding real estate), net; (ii) intangible impairments; (iii) other (income) expense, net; (iv) gain on sale of real estate, net of tax; and (v) Significant Acquisition Costs. Adjusted EBITDA Margin is calculated by dividing Adjusted EBITDA by total revenues. We use multiples of current or projected Adjusted EBITDA in conjunction with our discounted cash flow models to determine our estimated overall enterprise valuation and to evaluate acquisition targets. We believe Adjusted EBITDA and Adjusted EBITDA Margin provide our current and potential investors with relevant and useful information regarding our ability to generate cash flow to support business investment. These measures are an integral part of the internal reporting system we use to assess and evaluate the operating performance of our business.

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

(1)	There was no tax impact associated with the gain on sale of real estate recognized during the three and six months ended June 30, 2017.

Table of Contents

Adjusted EPS

Adjusted EPS is defined as reported earnings per share fully diluted from continuing operations excluding: (1) (gain) loss on disposal/write-down of property, plant and equipment (excluding real estate), net; (2) gain on sale of real estate, net of tax; (3) intangible impairments; (4) other (income) expense, net; (5) Significant Acquisition Costs; and (6) the tax impact of reconciling items and discrete tax items. Adjusted EPS includes income (loss) attributable to noncontrolling interests.

The difference between our effective tax rate and our structural tax rate (or adjusted effective tax rate) for the three and six months ended June 30, 2017 and 2018, respectively, is primarily due to (i) the reconciling items above, which impact our reported income (loss) from continuing operations before provision (benefit) for income taxes but have an insignificant impact on our reported provision (benefit) for income taxes and (ii) other discrete tax items. Our structural tax rate for purposes of the calculation of Adjusted EPS for the three and six months ended June 30, 2017 and 2018 was 21.3% and 21.8%, respectively.

FFO (Nareit) and FFO (Normalized)

Funds from operations (“FFO”) is defined by the National Association of Real Estate Investment Trusts ("Nareit") and us as net income (loss) excluding depreciation on real estate assets and gain on sale of real estate, net of tax ("FFO (Nareit)"). FFO (Nareit) does not give effect to real estate depreciation because these amounts are computed, under GAAP, to allocate the cost of a property over its useful life. Because values for well-maintained real estate assets have historically increased or decreased based upon prevailing market conditions, we believe that FFO (Nareit) provides investors with a clearer view of our operating performance. Our most directly comparable GAAP measure to FFO (Nareit) is net income (loss). Although Nareit has published a definition of FFO, modifications to FFO (Nareit) are common among REITs as companies seek to provide financial measures that most meaningfully reflect their particular business. Our definition of FFO (Normalized) excludes certain items included in FFO (Nareit) that we believe are not indicative of our core operating results, specifically: (1) (gain) loss on disposal/write-down of property, plant and equipment (excluding real estate), net; (2) intangible impairments; (3) other (income) expense, net; (4) Significant Acquisition Costs; (5) the tax impact of reconciling items and discrete tax items; (6) loss (income) from discontinued operations, net of tax; and (7) loss (gain) on sale of discontinued operations, net of tax.

Critical Accounting Policies

Our discussion and analysis of our financial condition and results of operations are based upon our Condensed Consolidated Financial Statements, which have been prepared in accordance with GAAP. The preparation of these financial statements requires us to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities at the date of the financial statements and for the period then ended. On an ongoing basis, we evaluate the estimates used. We base our estimates on historical experience, actuarial estimates, current conditions and various other assumptions that we believe to be reasonable under the circumstances. These estimates form the basis for making judgments about the carrying values of assets and liabilities and are not readily apparent from other sources. Actual results may differ from these estimates. Our critical accounting policies include the following, which are listed in no particular order:


•	Revenue Recognition


•	Accounting for Acquisitions


•	Impairment of Tangible and Intangible Assets


•	Income Taxes

Further detail regarding our critical accounting policies can be found in "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" in our Annual Report, and the Consolidated Financial Statements and the Notes included therein. We have determined that no material changes concerning our critical accounting policies have occurred since December 31, 2017, other than the adoption of ASU 2014-09, as described in Note 2.c. to Notes to Condensed Consolidated Financial Statements included in this Quarterly Report.

(1)	Constant currency growth rates are calculated by translating the 2017 results at the 2018 average exchange rates.


(2)	Our internal revenue growth rate, which is a non-GAAP measure, represents the year-over-year growth rate of our revenues excluding the impact of business acquisitions, divestitures, foreign currency exchange rate fluctuations and the impact of the adoption of ASU 2014-09. Our internal revenue growth rate includes the impact of acquisitions of customer relationships.

Storage Rental Revenues

In the three and six months ended June 30, 2018, the increase in reported consolidated storage rental revenues was driven by the favorable impact of acquisitions/divestitures, consolidated internal storage rental revenue growth and favorable fluctuations in foreign currency exchange rates. The impact of acquisitions/divestitures, net of the impact of the adoption of ASU 2014-09, contributed 7.6% to the reported storage rental revenue growth rates for the six months ended June 30, 2018 compared to the prior year period, primarily driven by recent acquisitions in our Global Data Center Business segment. Internal storage rental revenue growth of 2.8% in the six months ended June 30, 2018 compared to the prior year period was driven by internal storage rental revenue growth of 2.4% in our North American Records and Information Management Business segment, driven by revenue management programs, as well as internal storage rental revenue growth of 0.9%, 1.9% and 5.8% in our North American Data Management Business, Western European Business and Other International Business segments, respectively, primarily driven by volume increases. Excluding the impact of acquisitions/divestitures, global records management net volumes as of June 30, 2018 increased by 0.2% over the ending volume as of June 30, 2017. Global records management reported net volumes, including acquisitions/divestitures, as of June 30, 2018 increased by 1.5% over the ending volume at June 30, 2017, supported by volume increases of 0.5% and 9.0% in our Western European Business and Other International Business segments, respectively, partially offset by a volume decrease of 1.2% in our North American Records and Information Management Business segment. Foreign currency exchange rate fluctuations increased our reported storage rental revenue growth rate for the six months ended June 30, 2018 by 2.0%, compared to the prior year period.

Service Revenues

In the three and six months ended June 30, 2018, the increase in reported consolidated service revenues was driven by internal service revenue growth, the favorable impact of acquisitions/divestitures and favorable fluctuations in foreign currency exchange rates. The net impact of acquisitions/divestitures and the adoption of ASU 2014-09 contributed 3.5% to the reported service revenue growth rates for the six months ended June 30, 2018, compared to the prior year period. Internal service revenue growth of 4.2% for the six months ended June 30, 2018, compared to the prior year period was primarily driven by increased secured shredding revenues and increased project activity in our North American Records and Information Management Business segment and project activity in our Other International Business and Western European Business segments, partially offset by continued declines in service revenue activity levels in our North American Data Management Business segment, as the storage business becomes more archival in nature. Foreign currency exchange rate fluctuations increased our reported service revenue growth rate for the six months ended June 30, 2018 by 2.0%, compared to the prior year period.

Total Revenues

For the reasons stated above, our reported consolidated revenues increased $111.0 million, or 11.7%, to $1,060.8 million and $214.6 million, or 11.4%, to $2,103.3 million for the three and six months ended June 30, 2018, respectively, from $949.8 million and $1,888.7 million for the three and six months ended June 30, 2017, respectively. The net impact of acquisitions/divestitures contributed 6.1% to the reported consolidated revenue growth rate for the six months ended June 30, 2018 compared to the prior year period, primarily driven by recent acquisitions in our Global Data Center Business segment. Consolidated internal revenue growth was 3.3% in the six months ended June 30, 2018 compared to the prior year period. Foreign currency exchange rate fluctuations increased our reported consolidated revenue growth rate for the six months ended June 30, 2018 by 2.0%, compared to the prior year period.

Internal Growth—Eight-Quarter Trend



	2016				2017								2018
	Third Quarter		Fourth Quarter		First Quarter		Second Quarter		Third Quarter		Fourth Quarter		First Quarter		Second Quarter
Storage Rental Revenue	2.1	%	2.9	%	3.0	%	4.8	%	3.5	%	4.2	%	3.7	%	1.9	%
Service Revenue	(1.3	)%	(0.9	)%	0.6	%	(1.1	)%	(0.2	)%	(0.1	)%	1.4	%	7.6	%
Total Revenue	0.8	%	1.4	%	2.0	%	2.5	%	2.0	%	2.5	%	2.8	%	4.1	%

We expect our consolidated internal storage rental revenue growth rate for 2018 to be approximately 3.0% to 3.5%. During the past eight quarters, our internal storage rental revenue growth rate has ranged between 1.9% and 4.8%. In the second quarter of 2017, consolidated internal storage rental revenue growth and consolidated total internal revenue growth benefited by approximately 0.8% and 0.5%, respectively, from a $4.2 million customer termination fee in our Global Data Center Business segment. Conversely, consolidated internal storage rental revenue growth and consolidated total internal revenue growth for the second quarter of 2018 were negatively impacted by the 0.8% and 0.5%, respectively, related to the termination fee mentioned above. Our internal storage rental revenue growth rates have been relatively stable over the past two fiscal years, as internal storage rental revenue growth for full year 2016 and 2017 was 2.3% and 3.9%, respectively. At various points in the economic cycle, internal storage rental revenue growth may be influenced by changes in pricing and volume. In North America, internal storage rental revenue growth in 2017 resulted primarily from revenue management programs in our North American Records and Information Management Business segment as well as internal storage rental revenue growth in our North American Data Management Business segment, although North America volume continued to be flat in 2017 due to us receiving fewer documents from customers. For the first half of 2018, we experienced flat to modestly decreasing volume growth in our North American Records and Information Management Business and North American Data Management Business segments, with organic growth coming primarily from revenue management programs in these segments and volume growth in our Other International Business segment. We expect this trend to continue for the remainder of 2018.

Our internal service revenue growth has been negatively impacted by declining activity rates as stored records are becoming less active. Additionally, the internal growth rate for service revenue is inherently more volatile than the internal growth rate for storage rental revenues due to the more discretionary nature of certain services we offer, such as large special projects, and, as a commodity, the volatility of pricing for recycled paper. These revenues, which are often event-driven and impacted to a greater extent by economic downturns as customers defer or cancel the purchase of certain services as a way to reduce their short-term costs, may be difficult to replicate in future periods. The internal growth rate for total service revenues over the past eight quarters reflects reduced retrieval/re-file activity and a related decrease in transportation revenues within our North American Records and Information Management Business and Western European Business segments, as well as continued service declines in service revenue activity levels in our North American Data Management Business segment as the storage business becomes more archival in nature. The internal service revenue growth of 7.6% in the second quarter of 2018 reflects strong contribution from our secure shredding business, which benefited from higher recycled paper prices as well as higher destruction activity in the quarter.

Labor

Labor expenses decreased to 19.8% of consolidated revenues in the six months ended June 30, 2018 compared to 21.0% in the six months ended June 30, 2017. The decrease in labor expenses as a percentage of consolidated revenues was primarily driven by an approximately 130 basis point decrease in labor expenses associated with our North American Records and Information Management Business segment as a percentage of consolidated revenues, primarily associated with wages and benefits growing at a lower rate than revenue, partially attributable to synergies associated with our acquisition of Recall and cost management initiatives. On a constant dollar basis, labor expenses for the six months ended June 30, 2018 increased by $11.8 million, or 2.9%, compared to the prior year period, primarily driven by recent acquisitions.

Facilities

Facilities expenses increased to 15.4% of consolidated revenues in the six months ended June 30, 2018 compared to 15.1% in the six months ended June 30, 2017. The 30 basis point increase in facilities expenses as a percentage of consolidated revenues was driven by a 100 basis point increase in facilities expenses in our Global Data Center Business segment, primarily driven by an increase in utility costs supporting power generation as a result of recent acquisitions, partially offset by a 75 basis point decrease in facilities expenses in our North American Records and Information Management Business segment partially attributable to synergies associated with our acquisition of Recall. On a constant dollar basis, facilities expenses for the six months ended June 30, 2018 increased by $34.1 million, or 11.7%, compared to the prior year period, primarily driven by recent acquisitions in our Global Data Center Business segment.

Table of Contents

Transportation

Transportation expenses decreased to 3.7% of consolidated revenues in the six months ended June 30, 2018 compared to 3.8% in the six months ended June 30, 2017. The decrease in transportation expenses as a percentage of consolidated revenues was driven by a decrease in vehicle lease and maintenance expenses, primarily associated with our North American Records and Information Management Business segment. On a constant dollar basis, transportation expenses for the six months ended June 30, 2018 increased by $6.4 million, or 8.9%, compared to the prior year period, primarily driven by increases in third party carrier, vehicle insurance and fuel costs.

Product Cost of Sales and Other

Product cost of sales and other, which includes cartons, media and other service, storage and supply costs and is highly correlated to service revenue streams, particularly project revenues, decreased to 3.8% of consolidated revenues for the six months ended June 30, 2018 compared to 4.0% in the six months ended June 30, 2017. The decrease in product cost of sales and other as a percentage of revenue was driven by special project costs. On a constant dollar basis, product cost of sales and other increased by $2.7 million, or 3.6%, compared to the prior year period, primarily driven by project costs.

Significant Acquisition Costs

Significant Acquisition Costs included in cost of sales were $13.0 million and $2.1 million in the six months ended June 30, 2017 and 2018, respectively, and primarily consisted of employee severance costs and facility integration costs associated with the Recall acquisition.

General and Administrative

General and administrative expenses decreased to 12.9% of consolidated revenues in the six months ended June 30, 2018 compared to 13.8% in the six months ended June 30, 2017. The decrease in general and administrative expenses as a percentage of consolidated revenues was driven mainly by a decrease in compensation expense, partially attributable to synergies associated with our acquisition of Recall, as well as lower professional fees. On a constant dollar basis, general and administrative expenses for the six months ended June 30, 2018 increased by $6.8 million, or 2.6%, compared to the prior year period, primarily driven by recent acquisitions in our Global Data Center Business segment.

Sales, Marketing & Account Management

Sales, marketing and account management expenses decreased to 6.3% of consolidated revenues in the six months ended June 30, 2018 compared to 6.6% in the six months ended June 30, 2017. The decrease in sales, marketing and account management expenses as a percentage of consolidated revenues was driven by a decrease in compensation expense, primarily due to the impact of our adoption of ASU 2014-09 related to capitalization of commissions and lower professional fees. On a constant dollar basis, sales, marketing and account management expenses for the six months ended June 30, 2018 increased by $5.0 million, or 4.0%, compared to the prior year period, primarily driven by recent acquisitions in our Global Data Center Business segment.

Information Technology

Information technology expenses increased to 3.6% of consolidated revenues in the six months ended June 30, 2018 compared to 3.3% in the six months ended June 30, 2017. Information technology expenses as a percentage of consolidated revenues reflect an increase in professional fees. On a constant dollar basis, information technology expenses for the six months ended June 30, 2018 increased by $13.8 million, or 21.9%, compared to the prior year period, primarily driven by an increase in professional fees.

Bad Debt Expense

We maintain an allowance for doubtful accounts that is calculated based on our past loss experience, current and prior trends in our aged receivables, current economic conditions, and specific circumstances of individual receivable balances. We continue to monitor our customers' payment activity and make adjustments based on their financial condition and in light of historical and expected trends. Bad debt expense for the six months ended June 30, 2018 increased by $9.7 million on a constant dollar basis compared to the prior year period, primarily driven by higher bad debt expense associated with our North American Records and Information Management Business segment.

Significant Acquisition Costs

Significant Acquisition Costs included in selling, general and administrative expenses were $27.6 million and $27.3 million in the six months ended June 30, 2017 and 2018, respectively, and primarily consisted of advisory and professional fees, as well as severance costs.

Depreciation and Amortization

Our depreciation and amortization charges result primarily from the capital-intensive nature of our business. The principal components of depreciation relate to storage systems, which include racking structures, buildings, building and leasehold improvements and computer systems hardware and software. Amortization relates primarily to customer relationship intangible assets and data center in-place leases and tenant relationships. Both depreciation and amortization are impacted by the timing of acquisitions.

Depreciation expense increased $23.0 million, or 11.4%, on a reported dollar basis for the six months ended June 30, 2018 compared to the six months ended June 30, 2017, primarily due to recent acquisitions in our Global Data Center Business segment. See Note 2.f. to Notes to Consolidated Financial Statements included in our Annual Report for additional information regarding the useful lives over which our property, plant and equipment is depreciated.

Amortization expense increased $41.0 million, or 80.5%, on a reported dollar basis for the six months ended June 30, 2018 compared to the six months ended June 30, 2017, primarily due to recent acquisitions in our Global Data Center Business segment and, to a lesser extent, the adoption of ASU 2014-09.

OTHER EXPENSES, NET

Interest Expense, Net

Consolidated interest expense, net increased $23.7 million to $199.7 million in the six months ended June 30, 2018 from $176.0 million in the six months ended June 30, 2017. This increase was a result of higher borrowings during the current year period compared to the prior year period. Our weighted average interest rate was 4.8% and 5.4% at June 30, 2018 and 2017, respectively. See Note 5 to Notes to Condensed Consolidated Financial Statements included in this Quarterly Report for additional information regarding our indebtedness.

Foreign Currency Transaction Losses (Gains)

We recorded net foreign currency transaction losses of $3.2 million in the six months ended June 30, 2018, based on period-end exchange rates. These losses resulted primarily from the impact of changes in the exchange rate of the Brazilian real against the United States dollar compared to December 31, 2017 on our intercompany balances with and between certain of our subsidiaries. These losses were partially offset by gains resulting primarily from the impact of changes in the exchange rate of each of the British pound sterling and Canadian dollar against the United States dollar compared to December 31, 2017 on our intercompany balances with and between certain of our subsidiaries and the Euro Notes (as defined below).

We recorded net foreign currency transaction losses of $16.0 million in the six months ended June 30, 2017, based on period-end exchange rates. These losses resulted primarily from the impact of changes in the exchange rate of each of the British pound sterling, Canadian dollar and Euro against the United States dollar compared to December 31, 2016 on our intercompany balances with and between certain of our subsidiaries. These losses were partially offset by gains resulting primarily from the impact of changes in the exchange rate of each of the Mexican peso and Russian ruble against the United States dollar compared to December 31, 2016 on our intercompany balances with and between certain of our subsidiaries.

Other, net

Other, net for the three and six months ended June 30, 2017 includes a gain of $38.9 million associated with the Russia and Ukraine Divestment.

Provision for Income Taxes

Our effective tax rates for the three and six months ended June 30, 2017 were 18.1% and 16.2%, respectively. The primary reconciling items between the then current federal statutory tax rate of 35.0% and our overall effective tax rate for the three months ended June 30, 2017 were the benefit derived from the dividends paid deduction and differences in the rates of tax at which our foreign earnings are subject. The primary reconciling items between the then current federal statutory tax rate of 35.0% and our overall effective tax rate for the six months ended June 30, 2017 were the benefit derived from the dividends paid deduction, differences in the rates of tax at which our foreign earnings are subject and a release of valuation allowances on certain of our foreign net operating losses of $7.5 million as a result of the merger of certain of our foreign subsidiaries. Our effective tax rates for the three and six months ended June 30, 2018 were 21.9% and 16.5%, respectively. The primary reconciling items between the current federal statutory tax rate of 21.0% and our overall effective tax rate for the three months ended June 30, 2018 were the benefit derived from the dividends paid deduction and the impact of differences in the tax rates at which our foreign earnings are subject, including foreign exchange gains and losses in different jurisdictions with different tax rates. The primary reconciling items between the current federal statutory tax rate of 21.0% and our overall effective tax rate for the six months ended June 30, 2018 were the benefit derived from the dividends paid deduction, a discrete tax benefit of approximately $14.0 million associated with the resolution of a tax matter (as disclosed in Note 7 to Notes to Consolidated Financial Statements included in our Annual Report), and the impact of differences in the tax rates at which our foreign earnings are subject, including foreign exchange gains and losses in different jurisdictions with different tax rates.

Tax Reform

a. Deemed Repatriation Transition Tax

Our estimate of the amount of Undistributed E&P deemed repatriated under the Tax Reform Legislation in our taxable year ending December 31, 2017 is approximately $186.0 million (the “Estimated Undistributed E&P”). We will opt to include the full amount of Estimated Undistributed E&P in our 2017 taxable income, rather than spread it over eight years (as permitted by the Tax Reform Legislation). Accordingly, included in our REIT taxable income for 2017 was approximately $82.0 million related to the deemed repatriation of Undistributed E&P (the “Deemed Repatriation Taxable Income”).

b. Global Intangible Low-Taxed Income

For taxable years beginning after December 31, 2017, the Tax Reform Legislation introduced new provisions intended to prevent the erosion of the United States federal income tax base through the taxation of certain global intangible low-taxed income (“GILTI”). The GILTI provision created a new requirement that certain income earned by controlled foreign corporations (“CFCs”) must be included currently in the gross income of the CFC’s United States tax resident shareholder. Generally, GILTI is the excess of the United States shareholder's pro rata portion of the income of its foreign subsidiaries over the net deemed tangible income return of such subsidiaries.

The GILTI provision also provides for certain deductions against the inclusion of GILTI in taxable income; however, REITs are not eligible for such deductions. Therefore, 100% of our GILTI is included in our taxable income and may increase the required distribution to our stockholders, similar to the Subpart F income inclusion we are subject to as a REIT.

We are in the process of developing our estimates of GILTI. It is unclear at this time whether the GILTI inclusion will be considered as qualifying income for the purpose of the REIT gross income tests that we are required to satisfy. The United States Treasury Department and the Internal Revenue Service have authority to issue guidance clarifying that GILTI would be qualifying income and we expect that they will. The timing of such guidance is unclear and there can be no assurance that such guidance will be provided. At this time, we do not expect the GILTI provision will impact our provision for income taxes. However, the GILTI provision may impact the amount and characterization of dividends that we expect to pay in future taxable years.

c. Interest Deduction Limitation

The Tax Reform Legislation also limits, for certain entities, the deduction of net interest expense to the sum of business interest income plus 30% of adjusted taxable income (the “Interest Deduction Limitation”). Adjusted taxable income is defined in the Tax Reform Legislation as taxable income before interest, taxes, depreciation and amortization for taxable years beginning after December 31, 2017 and before January 1, 2022, and is defined as taxable income before interest and taxes for taxable years beginning after December 31, 2021.

Table of Contents

The Interest Deduction Limitation does not apply to taxpayers that qualify, and make an election, to be treated as a “real property trade or business”. As a REIT, if Iron Mountain Incorporated ("IMI"), including all of our QRSs, were to make an election to be treated as a "real property trade or business", then the interest deduction limitation would not apply. However, IMI would be required to utilize the alternative depreciation system for its real property. We do not believe our TRSs are eligible for treatment as a "real property trade or business".

If IMI does not elect to be treated as a “real property trade or business”, we will remain subject to the Interest Deduction Limitation and may be limited in the amount of interest expense we can deduct for United States federal income tax purposes beginning in our taxable year ending December 31, 2018. If we are limited in our ability to fully deduct our interest expense for the 2018 taxable year, we will consider making an election to be treated as a "real property trade or business" to avoid such limitation.

(LOSS) INCOME FROM DISCONTINUED OPERATIONS, NET OF TAX

Loss from discontinued operations, net of tax was $2.4 million and $0.8 million for the six months ended June 30, 2017 and 2018, respectively, primarily related to the operations of the Recall Divestments (as defined in Note 14 to Notes to Consolidated Financial Statements included in our Annual Report).

NONCONTROLLING INTERESTS

For the six months ended June 30, 2017 and 2018, net income attributable to noncontrolling interests resulted in a decrease in net income attributable to IMI of $2.9 million and $0.6 million, respectively. These amounts represent our noncontrolling partners' share of earnings/losses in our majority-owned international subsidiaries that are consolidated in our operating results.

For the six months ended June 30, 2018, reported revenue in our North American Records and Information Management Business segment increased 4.8%, compared to the six months ended June 30, 2017, due to internal revenue growth, the favorable net impact of acquisitions and the adoption of ASU 2014-09, as well as fluctuations in foreign currency exchange rates. Internal revenue growth of 3.9% in the six months ended June 30, 2018 was primarily the result of internal storage rental revenue growth of 2.4% in the six months ended June 30, 2018, driven by revenue management programs and internal service revenue growth of 6.0% in the six months ended June 30, 2018, driven by growth in secure shredding revenues and increased project activity. The net impact of acquisitions and the adoption of ASU 2014-09 contributed 0.4% to the reported revenue growth rates in our North American Records and Information Management Business segment for the six months ended June 30, 2018, compared to the prior year period. Adjusted EBITDA margin increased 180 basis points during the six months ended June 30, 2018 compared to the six months ended June 30, 2017, primarily driven by a decrease in wages and benefits as a percentage of segment revenue, partially attributable to synergies associated with our acquisition of Recall, cost management initiatives and the capitalization of certain commissions as a result of our adoption of ASU 2014-09.

(2)	Segment Adjusted EBITDA Margin is calculated by dividing Segment Adjusted EBITDA by total segment revenues.

For the six months ended June 30, 2018, reported revenue in our North American Data Management Business segment decreased 0.3%, compared to the six months ended June 30, 2017, primarily due to negative internal revenue growth partially offset by favorable fluctuations in foreign currency exchange rates. The negative internal revenue growth for the six months ended June 30, 2018 of 0.6% is primarily attributable to a decline in internal service of 3.8% in the six months ended June 30, 2018 due to continued declines in service revenue activity levels as the business becomes more archival in nature, partially offset by internal storage rental revenue growth of 0.9% in the six months ended June 30, 2018, primarily attributable to volume increases and the impact of revenue management programs. Adjusted EBITDA margin decreased 60 basis points during the six months ended June 30, 2018 compared to the six months ended June 30, 2017, primarily associated with investments in product management and development.

(2)	Segment Adjusted EBITDA Margin is calculated by dividing Segment Adjusted EBITDA by total segment revenues.

In the six months ended June 30, 2018, reported revenue in our Other International Business segment increased 8.1%, compared to the six months ended June 30, 2017, due to internal revenue growth, favorable fluctuations in foreign currency exchange rates and the favorable impact of acquisitions/divestitures. Internal revenue growth for the six months ended June 30, 2018 was 5.1%, supported by 5.8% internal storage rental revenue growth, primarily due to volume increases, and 3.9% internal service revenue growth, primarily due to increased project activity. The net impact of acquisitions/divestitures contributed 1.7% to reported revenue growth for the six months ended June 30, 2018, compared to the prior year period. For the six months ended June 30, 2018, foreign currency exchange rate fluctuations increased our reported revenues for the Other International Business segment by 1.3% compared to the prior year period primarily due to the strengthening of the Australian dollar against the United States dollar. Adjusted EBITDA margin of 29.4% for the six months ended June 30, 2018 increased 20 basis point compared to the six months ended June 30, 2017, primarily due to compensation growing at a lower rate than revenue, in part due to cost management initiatives, partially offset by increases in facility maintenance costs and bad debt expense.

For the six months ended June 30, 2018, reported revenue in our Global Data Center Business segment increased 512.1% compared to the six months ended June 30, 2017, due to the favorable impact of acquisitions. The impact of acquisitions contributed 514.2% to the reported revenue growth rate in our Global Data Center Business segment for the six months ended June 30, 2018 compared to the prior year period (see Note 4 of Notes to Condensed Consolidated Financial Statements included in this Quarterly Report for additional acquisition details). Internal revenue growth for the three months ended June 30, 2018 was negative 21.0%. The negative internal revenue growth was primarily driven by a $4.2 million customer termination fee in the second quarter of 2017. Excluding the impact of this termination fee, internal revenue growth for the three months ended June 30, 2018 was 34.5%. Adjusted EBITDA increased $38.2 million for the six months ended June 30, 2018 compared to the prior year period, primarily due to recent acquisitions.

During the six months ended June 30, 2018, Adjusted EBITDA in the Corporate and Other Business segment as a percentage of consolidated revenues improved 50 basis points compared to the six months ended June 30, 2017. Adjusted EBITDA in the Corporate and Other Business segment decreased $4.6 million in the six months ended June 30, 2018 compared to the six months ended June 30, 2017, primarily driven by higher professional fees, partially offset by profitability associated with recent acquisitions in our Adjacent Businesses operating segment.

Liquidity and Capital Resources

The following is a summary of our cash balances and cash flows (in thousands) as of and for the six months ended June 30,



	2017			2018
Cash flows from operating activities - continuing operations	$	322,040		$	393,806
Cash flows from investing activities - continuing operations	(220,970		)	(1,921,496		)
Cash flows from financing activities - continuing operations	(61,584		)	798,753
Cash and cash equivalents at the end of period	291,019			188,192

Cash Flows from Operating Activities

For the six months ended June 30, 2018, cash provided by operating activities increased by $71.8 million compared to the prior year period. The primary factors that impacted the increase in cash provided by operating activities were an increase in net income (including non-cash charges and realized foreign exchange losses) of $91.1 million, offset by an increase in cash used in working capital of $19.3 million, primarily related to the timing of the payment of certain accrued expenses.

Cash Flows from Investing Activities

Our significant investing activities during the six months ended June 30, 2018 are highlighted below:


•	We paid cash for acquisitions (net of cash acquired) of $1,666.9 million, primarily funded by the net proceeds of our issuance of the 5¹/₄% Notes (as defined below), the net proceeds of the Equity Offering and Over-Allotment Option (both as defined below) and borrowings under our Revolving Credit Facility.

•

We paid cash for capital expenditures of $217.6 million. Our business requires capital expenditures to maintain our ongoing operations, support our expected revenue growth and new products and services, and increase our profitability. All of these expenditures are included in the cash flows from investing activities. Additional details of our capital spending is included in the Capital Expenditures section below.


•	We acquired customer relationships, customer inducements (which consists of permanent withdrawal fees following the adoption of ASU 2014-09) and Contract Fulfillment Costs (as defined in Note 2.c. to Notes to Condensed Consolidated Financial Statements included in this Quarterly Report) during the six months ended June 30, 2018 of $23.4 million, $4.0 million and $9.8 million, respectively.

Excluding capital expenditures associated with potential future acquisitions, opportunistic real estate investments and capital expenditures associated with the integration of Recall, we expect our capital expenditures on real estate and non-real estate maintenance, as well as non-real estate investment, to be approximately $155.0 million to $165.0 million, our capital expenditures on our data center business to be approximately $200.0 million, and our capital expenditures on real estate investment, net of sales, and innovation to be approximately $75.0 million in the year ending December 31, 2018.

Cash Flows from Financing Activities

Our significant financing activities during the six months ended June 30, 2018 included:


•	Net proceeds of $371.0 million associated with the borrowings and repayments on our Revolving Credit Facility;


•	Proceeds, net of repayments, of $696.6 million associated with the borrowing of our Term Loan B (as defined below);


•	Net proceeds of $76.2 million from the exercise of the Over-Allotment Option;


•	Net proceeds of $8.7 million from sales of stock under our At The Market (ATM) Equity Program (as defined below);


•	Payment of dividends in the amount of $337.1 million on our common stock; and

a. Credit Agreement Amendments

As of December 31, 2017, we had a credit agreement, as amended as described below (the "Credit Agreement"), which consisted of a revolving credit facility (the "Revolving Credit Facility") and a term loan (the "Term Loan A") and was scheduled to terminate on August 21, 2022. The maximum amount permitted to be borrowed under the Revolving Credit Facility was $1,750.0 million and the original amount of the Term Loan A was $250.0 million.

On March 22, 2018, we entered into an amendment (the “2018 First Amendment”) to the Credit Agreement which provided us with the option to request additional commitments of up to $1,260.0 million under the Credit Agreement in the form of term loans or through increased commitments under the Revolving Credit Facility, subject to the conditions specified in the Credit Agreement. On June 4, 2018, we entered into another amendment (the "2018 Second Amendment") to the Credit Agreement which (i) reduced interest rate margins applicable to existing and future borrowings under the Revolving Credit Facility and Term Loan A by 0.25% and (ii) extended the maturity date of the Credit Agreement to June 4, 2023.

The amount available for borrowing under the Revolving Credit Facility as of June 30, 2018 was $866.8 million (which amount represents the maximum availability as of such date).

In connection with the 2018 First Amendment, we entered into an incremental term loan activation notice (the "Activation Notice") with certain lenders pursuant to which the lenders party to the Activation Notice agreed to provide commitments to fund an incremental term loan B in the amount of $700.0 million (the “Term Loan B”). On March 26, 2018, we borrowed the full amount of the Term Loan B, which matures on January 2, 2026. The Term Loan B was issued at 99.75% of par. The aggregate net proceeds of approximately $689.9 million, after paying commissions to the joint lead arrangers and net of the original discount, were used to repay outstanding borrowings under the Revolving Credit Facility. See Note 5 to Notes to Condensed Consolidated Financial Statements included in this Quarterly Report for additional details on the Term Loan B.

At June 30, 2018, we had $698.3 million outstanding on the Term Loan B and the interest rate in effect under the Term Loan B was 3.8%. The amount of debt for the Term Loan B reflects an unamortized original issue discount of $1.7 million as of June 30, 2018.

b . Australian Dollar Term Loan Amendment

On March 27, 2018, Iron Mountain Australia Group Pty Ltd, a wholly owned subsidiary of IMI, amended its AUD Term Loan (the "AUD Term Loan Amendment") to (i) increase the borrowings under the AUD Term Loan from 250.0 million Australian dollars to 350.0 million Australian dollars; (ii) increase the quarterly principal payments from 6.3 million Australian dollars per year to 8.8 million Australian dollars per year and (iii) decrease the interest rate on the AUD Term Loan from BBSY (an Australian benchmark variable interest rate) plus 4.3% to BBSY plus 3.875%. The AUD Term Loan matures in September 2022. All indebtedness associated with the AUD Term Loan was issued at 99% of par. The net proceeds associated with the AUD Term Loan Amendment of approximately 99.0 million Australian dollars (or approximately $75.6 million, based on the exchange rate between the Australian dollar and the United States dollar on March 29, 2018 (the closing date of the AUD Term Loan Amendment)), net of the original discount, were used to repay outstanding borrowings under the Revolving Credit Facility. See Note 5 to Notes to Condensed Consolidated Financial Statements included in this Quarterly Report for additional details on the AUD Term Loan.

Table of Contents



	December 31, 2017	June 30, 2018	Maximum/Minimum Allowable
Net total lease adjusted leverage ratio	5.0	5.6	Maximum allowable of 6.5

______________________________________________________________

At December 31, 2017, a portion of the net proceeds from the 5¹/₄% Notes, together with a portion of the net proceeds of the Equity Offering, were used to temporarily repay approximately $807.0 million of outstanding indebtedness under our Revolving Credit Facility until the closing of the IODC Transaction, which occurred on January 10, 2018. The bond leverage ratio at December 31, 2017 is calculated based on our outstanding indebtedness at this date, which reflects the temporary payment of the Revolving Credit Facility.

Noncompliance with these leverage and fixed charge coverage ratios would have a material adverse effect on our financial condition and liquidity.

_______________________________________________________________________________

Our ability to pay interest on or to refinance our indebtedness depends on our future performance, working capital levels and capital structure, which are subject to general economic, financial, competitive, legislative, regulatory and other factors which may be beyond our control. There can be no assurance that we will generate sufficient cash flow from our operations or that future financings will be available on acceptable terms or in amounts sufficient to enable us to service or refinance our indebtedness or to make necessary capital expenditures.

Equity Financings

a. At The Market (ATM) Equity Program

As described in greater detail in Note 13 to Notes to Consolidated Financial Statements included in our Annual Report, we entered into a distribution agreement (the “Distribution Agreement”) with a syndicate of 10 banks (the “Agents”) pursuant to which we may sell, from time to time, up to an aggregate sales price of $500.0 million of our common stock through the Agents (the “At The Market (ATM) Equity Program”). There were no shares of common stock sold under the At the Market (ATM) Equity Program during the three months ended June 30, 2018. During the six months ended June 30, 2018 under the At The Market (ATM) Equity Program, we sold an aggregate of 273,486 shares of common stock for gross proceeds of approximately $8.8 million, generating net proceeds of $8.7 million, after deducting commissions of $0.1 million. As of June 30, 2018, the remaining aggregate sale price of shares of our common stock available for distribution under the At The Market (ATM) Equity Program was approximately $431.2 million.

b. Equity Offering

Table of Contents

Pursuant to the Underwriting Agreement, we granted the Underwriters a 30-day option to purchase from us up to an additional 2,175,000 shares of common stock (the “Option Shares”) at the public offering price, less the underwriting commission and less an amount per share equal to any dividends or distributions declared by us and payable on the Firm Shares but not payable on the Option Shares (the “Over-Allotment Option"). On January 10, 2018, the Underwriters exercised the Over-Allotment Option in its entirety. The net proceeds to us from the exercise of the Over-Allotment Option, after deducting underwriters' commissions and the per share value of the dividend we declared on our common stock on October 24, 2017 (for which the record date was December 15, 2017) which was paid on January 2, 2018, was approximately $76.2 million. The net proceeds of the Equity Offering and the Over-Allotment Option, together with the net proceeds from the issuance of the 5¹/₄% Notes, were used to finance the purchase price of the IODC Transaction, and to pay related fees and expenses.

Acquisitions

a. 2018 Acquisitions of Data Centers

On January 10, 2018, we completed the IODC Transaction. At the closing of the IODC Transaction, we paid approximately $1,347.0 million. In addition to the amount paid at the closing of the IODC Transaction, there is the potential of $35.0 million in additional payments associated with the execution of future customer contracts.

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) 34.6 million British pounds sterling and (ii) 81.0 million Singapore dollars (or collectively, approximately $111.4 million, 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.

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. (collectively, "EvoSwitch"), a leading data center colocation space and solutions provider with a data center in Amsterdam (the "EvoSwitch Transaction"), for (i) cash consideration of 189.0 million Euros (or approximately $222.0 million, based upon the exchange rate between the Euro and the United States dollar on the closing date of the EvoSwitch Transaction) and (ii) $25.0 million of additional consideration in the form of future services we will provide to the seller.

b. Significant Acquisition Costs

Included in Significant Acquisition Costs are certain costs associated with the Recall Transaction and the IODC Transaction. We currently estimate total acquisition and integration expenditures associated with the Recall Transaction and acquisition expenditures associated with the IODC Transaction to be approximately $395.0 million, the majority of which is related to Recall and the majority of which is expected to be incurred by the end of 2018. This amount consists of (i) Significant Acquisition Costs and (ii) capital expenditures to integrate Recall with our existing operations.

The following table presents the operating and capital expenditures associated with the Recall Transaction and the IODC Transaction incurred for the three and six months ended June 30, 2017 and 2018 and the cumulative amount incurred through June 30, 2018 (in thousands):



	Year Ended December 31, 2017		Three Months Ended June 30, 2018		Six Months Ended June 30, 2018		Cumulative Total Through June 30, 2018
Significant Acquisition Costs	$	84,901	$	10,421	$	29,429	$	293,288
Recall Capital Expenditures	31,441		5,361		7,245		57,142
Total	$	116,342	$	15,782	$	36,674	$	350,430

Contractual Obligations

We expect to meet our cash flow requirements for the next twelve months from cash generated from operations, cash on hand, borrowings under the Credit Agreement and other financings (including the issuance of equity under the At The Market (ATM) Equity Program). We expect to meet our long-term cash flow requirements using the same means described above. We are currently operating above our long-term targeted leverage ratio, primarily as a result of costs incurred to fund the REIT conversion, the Recall Transaction and, more recently, the IODC Transaction. We expect to reduce our leverage ratio over time through effective capital allocation strategies and business growth.

Table of Contents

Inflation

Certain of our expenses, such as wages and benefits, insurance, occupancy costs and equipment repair and replacement, are subject to normal inflationary pressures. Although to date we have been able to offset inflationary cost increases with increased operating efficiencies, the negotiation of favorable long-term real estate leases and an ability to increase prices in our customer contracts (many of which contain provisions for inflationary price escalators), we can give no assurance that we will be able to offset any future inflationary cost increases through similar efficiencies, leases or increased storage rental or service charges.

Item 4. Controls and Procedures

Disclosure Controls and Procedures

The term "disclosure controls and procedures" is defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). These rules refer to the controls and other procedures of a company that are designed to ensure that information is recorded, processed, accumulated, summarized, communicated and reported to management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding what is required to be disclosed by a company in the reports that it files under the Exchange Act. As of June 30, 2018 (the "Evaluation Date"), we carried out an evaluation, under the supervision and with the participation of our management, including our chief executive officer and chief financial officer, of the effectiveness of our disclosure controls and procedures. Based upon that evaluation, our chief executive officer and chief financial officer concluded that, as of the Evaluation Date, our disclosure controls and procedures are effective.

Changes in Internal Control over Financial Reporting

Our management, with the participation of our principal executive officer and principal financial officer, is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act. Our internal control system is designed to provide reasonable assurance to our management and board of directors regarding the preparation and fair presentation of published financial statements.

There were no changes in our internal control over financial reporting during the quarter ended June 30, 2018 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Part II. Other Information

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

We did not sell any unregistered equity securities during the three months ended June 30, 2018, nor did we repurchase any shares of our common stock during the three months ended June 30, 2018.
