IRON MOUNTAIN INCORPORATED

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(In Thousands, Except Share and Per Share Data)

(Unaudited)

(1) General

The interim consolidated financial statements are presented herein and, in the opinion of management, reflect all adjustments of a normal recurring nature necessary for a fair presentation. Interim results are not necessarily indicative of results for a full year. Iron Mountain Incorporated, a Delaware corporation ("IMI"), and its subsidiaries ("we" or "us") store records, primarily paper documents and data backup media, and provide information management services in various locations throughout North America, Europe, Latin America and Asia Pacific. We have a diversified customer base consisting of commercial, legal, banking, healthcare, accounting, insurance, entertainment and government organizations.

The unaudited consolidated financial statements have been prepared pursuant to the rules and regulations of the United States Securities and Exchange Commission (the "SEC"). Certain information and footnote disclosures normally included in the annual financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") have been omitted pursuant to those rules and regulations, but we believe that the disclosures included herein are adequate to make the information presented not misleading. The Consolidated Financial Statements and Notes thereto, which are included herein, should be read in conjunction with the Consolidated Financial Statements and Notes thereto for the year ended December 31, 2014 included in our Current Report on Form 8-K filed with the SEC on May 7, 2015.

We have been organized and operating as a real estate investment trust for federal income tax purposes ("REIT") effective for our taxable year beginning January 1, 2014.

(2) Summary of Significant Accounting Policies

a.    Principles of Consolidation

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

b.    Cash, Cash Equivalents and Restricted Cash

Cash and cash equivalents include cash on hand and cash invested in highly liquid short-term securities, which have remaining maturities at the date of purchase of less than 90 days. Cash and cash equivalents are carried at cost, which approximates fair value.

At December 31, 2014, we had $33,860 of restricted cash associated with a collateral trust agreement with our insurance carrier related to our workers' compensation self-insurance program included in current assets on our Consolidated Balance Sheet. The restricted cash consisted primarily of United States Treasuries. We had no restricted cash at June 30, 2015.

c.    Foreign Currency

Local currencies are the functional currencies for our operations outside the United States, with the exception of certain foreign holding companies and our financing centers in Switzerland, whose functional currency is the United States dollar. In those instances where the local currency is the functional currency, assets and liabilities are translated at period-end exchange rates, and revenues and expenses are translated at average exchange rates for the applicable period. Resulting translation adjustments are reflected in the accumulated other comprehensive items, net component of Iron Mountain Incorporated Stockholders' Equity and Noncontrolling Interests in the accompanying Consolidated Balance Sheets. The gain or loss on foreign currency transactions, calculated as the difference between the historical exchange rate and the exchange rate at the applicable measurement date, including those related to (1) our previously outstanding 7¹/₄% GBP Senior Subordinated Notes due 2014 (the "7¹/₄% Notes"), (2) our 6³/₄% Euro Senior Subordinated Notes due 2018 (the "6³/₄% Notes"), (3) borrowings in certain foreign currencies under our revolving credit facility and (4) certain foreign currency denominated intercompany obligations of our foreign subsidiaries to us and between our foreign subsidiaries, which are not considered permanently invested, are included in other expense (income), net, in the accompanying Consolidated Statements of Operations.

	2014			2015		2014		2015
Total (gain) loss on foreign currency transactions	$	(4,347	)	$	1,656	$	2,091	$	23,922

d.    Goodwill and Other Intangible Assets

Goodwill and intangible assets with indefinite lives are not amortized but are reviewed annually for impairment or more frequently if impairment indicators arise. Other than goodwill, we currently have no intangible assets that have indefinite lives and which are not amortized. Separable intangible assets that are not deemed to have indefinite lives are amortized over their useful lives. We annually, or more frequently if events or circumstances warrant, assess whether a change in the lives over which our intangible assets are amortized is necessary.

We have selected October 1 as our annual goodwill impairment review date. We performed our most recent annual goodwill impairment review as of October 1, 2014 and concluded there was no impairment of goodwill at such date. As of December 31, 2014 and June 30, 2015, no factors were identified that would alter our October 1, 2014 goodwill assessment. In making this assessment, we relied on a number of factors including operating results, business plans, anticipated future cash flows, transactions and marketplace data. There are inherent uncertainties related to these factors and our judgment in applying them to the analysis of goodwill impairment. 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 at which level we performed our goodwill impairment analysis as of October 1, 2014 were as follows: (1) North American Records and Information Management; (2) technology escrow services that protect and manage source code (“Intellectual Property Management”); (3) the storage, assembly and detailed reporting of customer marketing literature and delivery to sales offices, trade shows and prospective customers’ sites based on current and prospective customer orders (“Fulfillment Services”); (4) North American Data Management; (5) Emerging Businesses (which primarily relates to our data center business in the United States and which is a component of our Corporate and Other Business segment); (6) the United Kingdom, Ireland, Norway, Austria, Belgium, France, Germany, Netherlands, Spain and Switzerland (“New Western Europe”); (7) the remaining countries in Europe in which we operate, excluding Russia, Ukraine and Denmark (“Emerging Markets - Eastern Europe” (formerly referred to as the "New Emerging Markets" reporting unit)); (8) Latin America; (9) Australia and Singapore; (10) China and Hong Kong (“Greater China”); (11) India; and (12) Russia, Ukraine and Denmark.

Beginning January 1, 2015, as a result of the changes in our reportable operating segments associated with our reorganization (see Note 7 for a description of our reportable operating segments), we reassessed the composition of our reporting units. Our North American Records and Information Management Business segment now consists of two reporting units: (1) North American Records and Information Management (which includes Intellectual Property Management and Fulfillment Services) and (2) North American Secure Shredding. Our Western European Business segment now consists of two reporting units: (1) the United Kingdom, Ireland and Norway (“UKI”) and (2) Austria, Belgium, France, Germany, Netherlands, Spain and Switzerland (“Continental Western Europe”). We have reassigned goodwill associated with the reporting units impacted by the reorganization among the new reporting units on a relative fair value basis. The fair value of each of our new reporting units was determined based on the application of a combined weighted average approach of preliminary fair value multiples of revenue and earnings and discounted cash flow techniques. These fair values represent our best estimate and preliminary assessment of goodwill allocations to each of the new reporting units on a relative fair value basis.

(1) We will finalize our preliminary estimates of fair value for these new reporting units once we finalize multi-year cash flow forecasts of such reporting units and conclude on the fair value of each new reporting unit based on the combined weighting of both fair value multiples and discounted cash flow techniques. To the extent final fair values of our new reporting units differ from our preliminary estimates, we will reassign goodwill amongst the new reporting units in a future period in which the final information is available to complete the fair values and the corresponding allocation of goodwill amongst the new reporting units.

(6) This reporting unit is included in the Other International Business segment.

As a result of the change in the composition of our reporting units noted above, we concluded that we had an interim triggering event, and, therefore, during the first quarter of 2015, we performed an interim goodwill impairment test, as of January 1, 2015, for the North American Records and Information Management, North American Secure Shredding, UKI and Continental Western Europe reporting units. We concluded that the goodwill for each of our new reporting units was not impaired as of such date. While we continue to refine our preliminary estimates of fair value of certain of our new reporting units for purposes of reallocating goodwill, we do not believe that any such changes to preliminary fair value estimates will result in a change in our conclusion that there is no goodwill impairment as of January 1, 2015.

e.    Stock-Based Compensation

We record stock-based compensation expense, utilizing the straight-line method, for the cost of stock options, restricted stock, restricted stock units ("RSUs"), performance units ("PUs") and shares of stock issued under our employee stock purchase plan ("ESPP") (together, "Employee Stock-Based Awards").

Stock-based compensation expense for Employee Stock-Based Awards included in the accompanying Consolidated Statements of Operations for the three and six months ended June 30, 2014 was $7,317 ($5,417 after tax or $0.03 per basic and diluted share) and $14,458 ($10,551 after tax or $0.05 per basic and diluted share), respectively. Stock-based compensation expense for Employee Stock-Based Awards for the three and six months ended June 30, 2015 was $7,921 ($5,467 after tax or $0.03 per basic and diluted share) and $14,777 ($10,413 after tax or $0.05 per basic and diluted share), respectively.

(2) Summary of Significant Accounting Policies (Continued)

The benefits associated with the tax deductions in excess of recognized compensation cost are required to be reported as financing activities in the accompanying Consolidated Statements of Cash Flows. This requirement reduces reported operating cash flows and increases reported financing cash flows. As a result, net financing cash flows from continuing operations included $(66) and $260 for the six months ended June 30, 2014 and 2015, respectively, from the (deficiency) benefit of tax deductions compared to recognized compensation cost. The tax benefit of any resulting excess tax deduction increases the Additional Paid-in Capital ("APIC") pool. Any resulting tax deficiency is deducted from the APIC pool.

Stock Options

Under our various stock option plans, options are generally granted with exercise prices equal to the market price of the stock on the date of grant; however, in certain instances, options are granted at prices greater than the market price of the stock on the date of grant. Certain of the options we issue become exercisable ratably over a period of ten years from the date of grant and have a contractual life of 12 years from the date of grant, unless the holder's employment is terminated sooner. As of June 30, 2015, ten-year vesting options represented 7.4% of total outstanding options. Certain of the options we issue become exercisable ratably over a period of five years from the date of grant and have a contractual life of ten years from the date of grant, unless the holder's employment is terminated sooner. As of June 30, 2015, five-year vesting options represented 46.1% of total outstanding options. The remainder of options we issue become exercisable ratably over a period of three years from the date of grant and have a contractual life of ten years from the date of grant, unless the holder's employment is terminated sooner. As of June 30, 2015, three-year vesting options represented 46.5% of total outstanding options. Our non-employee directors are considered employees for purposes of our stock option plans and stock option reporting. Options granted to our non-employee directors become exercisable immediately upon grant.

The weighted average fair value of options granted for the six months ended June 30, 2014 and 2015 was $5.60 and $4.99 per share, respectively. These values were estimated on the date of grant using the Black-Scholes option pricing model. The weighted average assumptions used for grants in the respective period are as follows:

	Six Months Ended June 30,
Weighted Average Assumptions	2014		2015
Expected volatility	33.9	%	28.6	%
Risk-free interest rate	2.06	%	1.70	%
Expected dividend yield	4	%	5	%
Expected life	6.8 years		5.5 years

Expected volatility is calculated utilizing daily historical volatility over a period that equates to the expected life of the option. The risk-free interest rate was based on the United States Treasury interest rates whose term is consistent with the expected life of the stock options. Expected dividend yield is considered in the option pricing model and represents our current annualized expected per share dividends over the current trade price of our common stock. The expected life (estimated period of time outstanding) of the stock options granted is estimated using the historical exercise behavior of employees.

Restricted Stock and Restricted Stock Units

Under our various equity compensation plans, we may also grant restricted stock or RSUs. Our restricted stock and RSUs generally have a vesting period of between three and five years from the date of grant. However, beginning in 2015, RSUs granted to our non-employee directors now vest immediately upon grant. All RSUs accrue dividend equivalents associated with the underlying stock as we declare dividends. Dividends will generally be paid to holders of RSUs in cash upon the vesting date of the associated RSU and will be forfeited if the RSU does not vest. The fair value of restricted stock and RSUs is the excess of the market price of our common stock at the date of grant over the purchase price (which is typically zero).

Cash dividends accrued and paid on RSUs for the three and six months ended June 30, 2014 and 2015 are as follows:

	Three Months Ended June 30,				Six Months Ended June 30,
	2014		2015		2014		2015

Performance Units

Under our various equity compensation plans, we may also make awards of PUs. For the majority of PUs, the number of PUs earned is determined based on our performance against predefined targets of revenue or revenue growth and return on invested capital ("ROIC"). The number of PUs earned may range from 0% to 150% (for PUs granted prior to 2014) and 0% to 200% (for PUs granted in 2014 and thereafter) 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 either the one-year performance period (for PUs granted prior to 2014) or the three-year performance period (for PUs granted in 2014 and thereafter). Certain PUs granted in 2013, 2014 and 2015 will be earned based on a market condition associated with the total return on our common stock in relation to a subset of the S&P 500 rather than the revenue growth and ROIC targets noted above. The number of PUs earned based on this market condition may range from 0% to 200% of the initial award. All of our PUs will be settled in shares of our common stock and are subject to cliff vesting three years from the date of the original PU grant. For those PUs subject to a one-year performance period, employees who subsequently terminate their employment after the end of the one-year performance period and on or after attaining age 55 and completing 10 years of qualifying service (the "Retirement Criteria") shall immediately and completely vest in any PUs earned based on the actual achievement against the predefined targets as discussed above (but delivery of the shares remains deferred). As a result, PUs subject to a one-year performance period are generally expensed over the shorter of (1) the vesting period, (2) achievement of the Retirement Criteria, which may occur as early as January 1 of the year following the year of grant or (3) a maximum of three years. For those PUs subject to a three-year performance period, employees who terminate their employment during the performance period and on or after meeting the Retirement Criteria are eligible for pro rated vesting, subject to the actual achievement against the predefined targets as discussed above, based on the number of full years of service completed following the grant date (but delivery of the shares remains deferred). As a result, PUs subject to a three-year performance period are generally expensed over the three-year performance period. Outstanding PUs accrue dividend equivalents associated with the underlying stock as we declare dividends. Dividends will generally be paid to holders of PUs in cash upon the settlement date of the associated PU and will be forfeited if the PU does not vest.

Cash dividends accrued and paid on PUs for the three and six months ended June 30, 2014 and 2015 are as follows:

	Three Months Ended June 30,				Six Months Ended June 30,
	2014		2015		2014		2015
Cash dividends on PUs accrued	$	142	$	214	$	292	$	425

(2) Summary of Significant Accounting Policies (Continued)

During the six months ended June 30, 2015, we issued 139,446 PUs. The majority of our PUs are earned based on our performance against revenue or revenue growth and ROIC targets during their applicable performance period; therefore, we forecast the likelihood of achieving the predefined revenue, revenue growth and ROIC 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 applicable performance period) or the actual PUs earned (at the one-year anniversary date for PUs granted prior to 2014, and at the three-year anniversary date for PUs granted in 2014 and thereafter) over the vesting period for each of the awards. For PUs earned based on a market condition, we utilized 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, 2015, we expected 25% and 100% achievement of the predefined revenue, revenue growth and ROIC targets associated with the awards of PUs made in 2014 and 2015, respectively.

The fair value of earned PUs that vested during the three and six months ended June 30, 2014 and 2015 is as follows:

	Three Months Ended June 30,				Six Months Ended June 30,
	2014		2015		2014		2015
Fair value of earned PUs that vested	$	2,266	$	44	$	6,296	$	2,107

Employee Stock Purchase Plan

We offer an ESPP in which participation is available to substantially all United States and Canadian employees who meet certain service eligibility requirements. The ESPP provides a way for our eligible employees to become stockholders on favorable terms. The ESPP provides for the purchase of our common stock by eligible employees through successive offering periods. We have historically had twosix-month offering periods per year, the first of which generally runs from June 1 through November 30 and the second of which generally runs from December 1 through May 31. During each offering period, participating employees accumulate after-tax payroll contributions, up to a maximum of 15% of their compensation, to pay the purchase price at the end of the offering. Participating employees may withdraw from an offering before the purchase date and obtain a refund of the amounts withheld as payroll deductions. At the end of the offering period, outstanding options under the ESPP are exercised, and each employee's accumulated contributions are used to purchase our common stock. The price for shares purchased under the ESPP is 95% of the fair market price at the end of the offering period, without a look-back feature. As a result, we do not recognize compensation expense for the ESPP shares purchased. For the six months ended June 30, 2014 and 2015, there were 69,567 shares and 59,569 shares, respectively, purchased under the ESPP. As of June 30, 2015, we have 901,069 shares available under the ESPP.

As of June 30, 2015, unrecognized compensation cost related to the unvested portion of our Employee Stock-Based Awards was $46,910 and is expected to be recognized over a weighted-average period of 2.2 years.

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

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

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

The calculation of basic and diluted income (loss) per share for the three and six months ended June 30, 2014 and 2015 is as follows:

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

g.    Revenues

Our revenues consist of storage rental revenues as well as service revenues and are reflected net of sales and value added taxes. Storage rental revenues, which are considered a key driver of financial performance for the storage and information management services industry, consist primarily of recurring periodic rental charges related to the storage of materials or data (generally on a per unit basis). Service revenues include charges for related service activities, which include: (1) the handling of records, including the addition of new records, temporary removal of records from storage, refiling of removed records and the destruction of records; (2) courier operations, consisting primarily of the pickup and delivery of records upon customer request; (3) secure shredding of sensitive documents and the related sale of recycled paper, the price of which can fluctuate from period to period; (4) other services, including the scanning, imaging and document conversion services of active and inactive records, or Document Management Solutions ("DMS"), which relate to physical and digital records, and project revenues; (5) customer termination and permanent withdrawal fees; (6) data restoration projects; (7) special project work; (8) Fulfillment Services; (9) consulting services; and (10) Intellectual Property Management and other technology services and product sales (including specially designed storage containers and related supplies).

We recognize revenue when the following criteria are met: persuasive evidence of an arrangement exists, services have been rendered, the sales price is fixed or determinable and collectability of the resulting receivable is reasonably assured. 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. Amounts related to future storage rental or prepaid service contracts for customers where storage rental fees or services are billed in advance are accounted for as deferred revenue and recognized ratably over the period the applicable storage rental or service is provided or performed. Revenues from the sales of products, which are included as a component of service revenues, are recognized when products are shipped and title has passed to the customer. Revenues from the sales of products have historically not been significant.

h.    Allowance for Doubtful Accounts and Credit Memo Reserves

We maintain an allowance for doubtful accounts and credit memos for estimated losses resulting from the potential inability of our customers to make required payments and potential disputes regarding billing and service issues. When calculating the allowance, we consider our past loss experience, current and prior trends in our aged receivables and credit memo activity, current economic conditions and specific circumstances of individual receivable balances. If the financial condition of our customers were to significantly change, resulting in a significant improvement or impairment of their ability to make payments, an adjustment of the allowance may be required. We charge-off uncollectible balances as circumstances warrant, generally, no later than one year past due.

i.    Income Taxes

As noted previously, we have been organized and operating as a REIT effective for our taxable year beginning January 1, 2014. As a REIT, we are generally permitted to deduct from our federal taxable income the dividends we pay to our stockholders. The income represented by such dividends is not subject to federal taxation at the entity level but may be taxed at the stockholder level. The income of our domestic taxable REIT subsidiaries (“TRSs”), which hold our domestic operations that may not be REIT‑compliant as currently operated and structured, is subject, as applicable, to federal and state corporate income tax. In addition, we and our subsidiaries continue to be subject to foreign income taxes in jurisdictions in which we have business operations or a taxable presence, regardless of whether assets are held or operations are conducted through subsidiaries disregarded for federal tax purposes or as TRSs. We will also be subject to a separate corporate income tax on any gains recognized during a specified period (generally ten years) following the REIT conversion that are attributable to “built‑in” gains with respect to the assets that we owned on January 1, 2014; this built‑in gains tax has been imposed on our depreciation recapture recognized into income in 2014 and generally will be imposed in subsequent years as a result of accounting method changes commenced in our pre‑REIT period. If we fail to remain qualified for taxation as a REIT, we will be subject to federal income tax at regular corporate tax rates. Even if we remain qualified for taxation as a REIT, we may be subject to some federal, state, local and foreign taxes on our income and property in addition to taxes owed with respect to our TRS operations. In particular, while state income tax regimes often parallel the federal income tax regime for REITs, many states do not completely follow federal rules and some do not follow them at all.

(2) Summary of Significant Accounting Policies (Continued)

We provide for income taxes during interim periods based on our estimate of the effective tax rate for the year. Discrete items and changes in our estimate of the annual effective tax rate are recorded in the period they occur. Our effective tax rate is subject to variability in the future due to, among other items: (1) changes in the mix of income between our qualified REIT subsidiaries and our TRSs, as well as between 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. We are subject to income taxes in the United States and numerous foreign jurisdictions. We are subject to examination by various tax authorities in jurisdictions in which we have business operations or a taxable presence. We regularly assess the likelihood of additional assessments by tax authorities and provide for these matters as appropriate. Although we believe our tax estimates are appropriate, the final determination of tax audits and any related litigation could result in changes in our estimates.

Accounting for income taxes requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the tax and financial reporting bases of assets and liabilities and for loss and credit carryforwards. Valuation allowances are provided when recovery of deferred tax assets does not meet the more likely than not standard as defined in GAAP.

We have elected to recognize interest and penalties associated with uncertain tax positions as a component of the provision (benefit) for income taxes in the accompanying Consolidated Statements of Operations. We recorded a decrease of $631 and an increase of $335 for gross interest and penalties for the three and six months ended June 30, 2014, respectively. We recorded an increase of $637 and $1,579 for gross interest and penalties for the three and six months ended June 30, 2015, respectively. We had $5,884 and $6,756 accrued for the payment of interest and penalties as of December 31, 2014 and June 30, 2015, respectively.

As a result of our REIT conversion, we recorded a net tax benefit of $230,051 and $212,151 during the three and six months ended June 30, 2014, respectively, for the revaluation of certain deferred tax assets and liabilities and other income taxes associated with the REIT conversion. The other primary reconciling items between the federal statutory rate of 35% and our overall effective tax rate in the three and six months ended June 30, 2014 were a $36,084 increase in our tax provision recognized in the second quarter of 2014 associated with incremental federal and state income taxes and foreign withholding taxes on earnings of our foreign subsidiaries no longer considered permanently invested and other net tax benefit related to the REIT conversion of $18,763 and $33,835, respectively, primarily related to the dividends paid deduction.

Our effective tax rates for the three and six months ended June 30, 2015 were 12.1% and 19.6%, respectively. The primary reconciling items between the federal statutory rate of 35% and our overall effective tax rate in the three and six months ended June 30, 2015 were the benefit derived from the dividends paid deduction, differences in the rates of tax at which our foreign earnings are subject, including foreign exchange gains and losses in different jurisdictions with different tax rates and state income taxes (net of federal tax benefit).

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

j.    Concentrations of Credit Risk

Financial instruments that potentially subject us to credit risk consist principally of cash and cash equivalents (including money market funds and time deposits), restricted cash (primarily United States Treasuries) and accounts receivable. The only significant concentrations of liquid investments as of December 31, 2014 relate to cash and cash equivalents and restricted cash held on deposit and as of June 30, 2015 relate to cash and cash equivalents. At December 31, 2014, we had money market funds with two "Triple A" rated money market funds and time deposits with three global banks. At June 30, 2015, we had time deposits with three global banks and no money market funds. We consider the "Triple A" rated money market funds and the global banks to be large, highly-rated investment-grade institutions. As per our risk management investment policy, we limit exposure to concentration of credit risk by limiting the amount invested in any one mutual fund to a maximum of $50,000 or in any one financial institution to a maximum of $75,000. As of December 31, 2014 and June 30, 2015, our cash and cash equivalents and restricted cash balance was $159,793 and $117,098, respectively, including money market funds and time deposits amounting to $53,032 and $20,802, respectively. The money market funds were invested substantially in United States Treasuries.

k.    Fair Value Measurements

Entities are permitted under GAAP to elect to measure many financial instruments and certain other items at either fair value or cost. We did not elect the fair value measurement option.

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

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

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

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

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

The assets and liabilities carried at fair value measured on a recurring basis as of December 31, 2014 and June 30, 2015, respectively, are as follows:

			Fair Value Measurements at December 31, 2014 Using
Description	Total Carrying Value at December 31, 2014		Quoted prices in active markets (Level 1)			Significant other observable inputs (Level 2)			Significant unobservable inputs (Level 3)

Trading Securities	10,960		10,086		(2)	874		(1)	—
Derivative Assets(3)	6,362		—			6,362			—

_______________________________________________________________________________

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

(2) Securities are measured at fair value using quoted market prices.

(3) Our 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 intercompany exposures, as more fully disclosed at 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.

Disclosures are required in the financial statements for items measured at fair value on a non-recurring basis. We did not have any material items that are measured at fair value on a non-recurring basis for the three and six months ended June 30, 2014 and 2015.

l.    Use of Estimates

The preparation of financial statements in conformity with GAAP requires us to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities at the date of the financial statements and for the period then ended. On an ongoing basis, we evaluate the estimates used. We base our estimates on historical experience, actuarial estimates, current conditions and various other assumptions that we believe to be reasonable under the circumstances. These estimates form the basis for making judgments about the carrying values of assets and liabilities and are not readily apparent from other sources. Actual results may differ from these estimates.

o.    Property, Plant and Equipment and Long-Lived Assets

We develop various software applications for internal use. Computer software costs associated with internal use software are expensed as incurred until certain capitalization criteria are met. Payroll and related costs for employees directly associated with, and devoting time to, the development of internal use computer software projects (to the extent time is spent directly on the project) are capitalized. During the three and six months ended June 30, 2014, we capitalized $4,861 and $9,758 of costs, respectively, associated with the development of internal use computer software projects. During the three and six months ended June 30, 2015, we capitalized $6,395 and $12,435 of costs, respectively, associated with the development of internal use computer software projects. Capitalization begins when the design stage of the application has been completed and it is probable that the project will be completed and used to perform the function intended. Capitalization ends when the asset is ready for its intended use. Depreciation begins when the software is placed in service. Computer software costs that are capitalized are periodically evaluated for impairment.

We review long-lived assets and all amortizable intangible assets for impairment whenever events or changes in circumstances indicate the carrying amount of such assets may not be recoverable. Recoverability of these assets is determined by comparing the forecasted undiscounted net cash flows of the operation to which the assets relate to their carrying amount. The operations are generally distinguished by the business segment and geographic region in which they operate. If the operation is determined to be unable to recover the carrying amount of its assets, the long-lived assets are written down, on a pro rata basis, to fair value. Fair value is determined based on discounted cash flows or appraised values, depending upon the nature of the assets.

As a result of our conversion to a REIT and in accordance with SEC rules applicable to REITs, we no longer report (gain) loss on the sale of real estate as a component of operating income, but we report it as a component of income (loss) from continuing operations. We report the (gain) loss on sale of property, plant and equipment (excluding real estate), along with any impairment, write-downs or involuntary conversions related to real estate, as a component of operating income. Previously reported amounts have been reclassified to conform to this presentation.

Consolidated (gain) loss on disposal/write-down of property, plant and equipment (excluding real estate), net was $(107) and $1,045 for the three and six months ended June 30, 2014, respectively. Losses in the six months ended June 30, 2014 were primarily associated with the write-off of certain software associated with our North American Records and Information Management Business segment. Consolidated loss on disposal/write-down of property, plant and equipment (excluding real estate), net was $515 and $848 for the three and six months ended June 30, 2015, respectively, and consisted primarily of the write-off of certain property associated with our North American Records and Information Management Business segment.

Consolidated gain on sale of real estate was $7,468, net of tax of $1,991, for the six months ended June 30, 2014 associated with the sale of two buildings in the United Kingdom.

p.    New Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU 2014-09"). ASU 2014-09 provides additional 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, (3) licenses, (4) time value of money and (5) contract costs. Further disclosures will be required to provide a better understanding of revenue that has been recognized and revenue that is expected to be recognized in the future from existing contracts. In July 2015, the FASB deferred the effective date of ASU 2014-09 for one year, making it effective for our year beginning January 1, 2018, with early adoption permitted as of January 1, 2017. We are currently evaluating the impact ASU 2014-09 will have on our consolidated financial statements.

In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements Going Concern (Subtopic 205-40) (“ASU 2014-15”). ASU 2014-15 requires management to assess an entity’s ability to continue as a going concern by incorporating and expanding upon certain principles of current United States auditing standards. Specifically, the amendments (1) provide a definition of the term “substantial doubt”, (2) require an evaluation every reporting period, including interim periods, (3) provide principles for considering the mitigating effect of management’s plans, (4) require certain disclosures when substantial doubt is alleviated as a result of consideration of management’s plans, (5) require an express statement and other disclosures when substantial doubt is still present, and (6) require an assessment for a period of one year after the date that the financial statements are issued (or available to be issued). ASU 2014‑15 is effective for us on January 1, 2017, with early adoption permitted. We do not believe that this pronouncement will have an impact on our consolidated financial statements.

In February 2015, the FASB issued ASU No. 2015‑02, Consolidation (Topic 810): Amendments to the Consolidation Analysis (“ASU 2015‑02”). ASU 2015‑02 affects reporting entities that are required to evaluate whether they should consolidate certain legal entities. ASU 2015‑02 is effective for us on January 1, 2016, with early adoption permitted. We do not believe that this pronouncement will have an impact on our consolidated financial statements.

In April 2015, the FASB issued ASU No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs (“ASU 2015-03”).  The amendments in ASU 2015-03 require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts.  The recognition and measurement guidance for debt issuance costs are not affected by the amendments in ASU 2015-03.  ASU 2015‑03 is effective for us on January 1, 2016, with early adoption permitted.  We do not believe that this pronouncement will have a material impact on our consolidated financial statements.

(3) Derivative Instruments and Hedging Activities

Every derivative instrument is required to be recorded in the balance sheet as either an asset or a liability measured at its fair value. Periodically, we acquire derivative instruments that are intended to hedge either cash flows or values that are subject to foreign exchange or other market price risk and not for trading purposes. We have formally documented our hedging relationships, including identification of the hedging instruments and the hedged items, as well as our risk management objectives and strategies for undertaking each hedge transaction. Given the recurring nature of our revenues and the long-term nature of our asset base, we have the ability and the preference to use long-term, fixed interest rate debt to finance our business, thereby preserving our long-term returns on invested capital. We target approximately 75% of our debt portfolio to be fixed with respect to interest rates. Occasionally, we may use interest rate swaps as a tool to maintain our targeted level of fixed rate debt. In addition, we may use borrowings in foreign currencies, either obtained in the United States or by our foreign subsidiaries, to hedge foreign currency risk associated with our international investments. Sometimes we enter into currency swaps to temporarily hedge an overseas investment, such as a major acquisition, while we arrange permanent financing or to hedge our exposure due to foreign currency exchange movements related to our intercompany accounts with and between our foreign subsidiaries. As of December 31, 2014 and June 30, 2015, none of our derivative instruments contained credit-risk related contingent features.

We have entered into a number of separate forward contracts to hedge our exposures in Euros, British pounds sterling and Australian dollars. As of June 30, 2015, we had outstanding forward contracts to purchase 212,500 Euros and sell $231,385 United States dollars to hedge our intercompany exposures with our European operations. At the maturity of the forward contracts, we may enter into new forward contracts to hedge movements in the underlying currencies. At the time of settlement, we either pay or receive the net settlement amount from the forward contract and recognize this amount in other expense (income), net in the Consolidated Statements of Operations as a realized foreign exchange gain or loss. At the end of each month, we mark the outstanding forward contracts to market and record an unrealized foreign exchange gain or loss for the mark-to-market valuation. We have not designated forward contracts as hedges.

Net cash payments (receipts) included in cash from operating activities related to settlements associated with foreign currency forward contracts for the three and six months ended June 30, 2014 and 2015, respectively, are as follows:

	Three Months Ended June 30,				Six Months Ended June 30,
	2014		2015		2014		2015
Net cash payments (receipts)	$	7,330	$	12,368	$	14,529	$	29,188

Total		$	11,748	$	(8,119	)	$	14,670	$	20,414

We have designated a portion of the 6³/₄% Notes as a hedge of net investment of certain of our Euro denominated subsidiaries. For the six months ended June 30, 2014 and 2015, we designated on average 58,735 and 35,786 Euros, respectively, of the 6³/₄% Notes as a hedge of net investment of certain of our Euro denominated subsidiaries. As a result, we recorded the following foreign exchange gains (losses), net of tax, 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,
	2014		2015			2014		2015

(4) Acquisitions

We account for acquisitions using the acquisition method of accounting, and, accordingly, the assets and liabilities acquired were 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. Cash consideration for our various acquisitions was primarily provided through borrowings under our credit facilities and cash equivalents on‑hand. The unaudited pro forma results of operations (including revenue and earnings) for the current and prior periods are not presented due to the insignificant impact of the 2014 and 2015 acquisitions on our consolidated results of operations.

In the first six months of 2015, in order to enhance our existing operations in the United States, United Kingdom, Canada, Australia and Chile, we completed six acquisitions for total consideration of approximately $18,400. These acquisitions included four storage and records management companies, one storage and data management company and one personal storage company. The individual purchase prices of these acquisitions ranged from approximately $2,300 to approximately $5,500.

A summary of the cumulative consideration paid and the preliminary allocation of the purchase price paid for these acquisitions is as follows:

Cash Paid (gross of cash acquired)	$	18,433		(1)
Total Consideration	18,433
Fair Value of Identifiable Assets Acquired:
Cash, Accounts Receivable, Prepaid Expenses, Deferred Income Taxes and Other	1,162
Property, Plant and Equipment(2)	4,050
Customer Relationship Assets(3)	9,922
Other Assets	361
Liabilities Assumed and Deferred Income Taxes(4)	(5,413		)
Total Fair Value of Identifiable Net Assets Acquired	10,082
Goodwill Initially Recorded	$	8,351

_______________________________________________________________________________

(1) Included in cash paid for acquisitions in the Consolidated Statements of Cash Flows for the six months ended June 30, 2015 is net cash acquired of $(325) and contingent and other payments of $3,606 related to acquisitions made in previous years.

(2) Consists primarily of buildings, racking structures, leasehold improvements and computer hardware and software.

(4) Acquisitions (Continued)

On June 8, 2015, we entered into a binding Scheme Implementation Deed (the “Recall Agreement”) with Recall Holdings Limited (“Recall”) to acquire Recall (the “Recall Transaction”) by way of a recommended court approved Scheme of Arrangement (the “Scheme”). Under the terms of the Recall Agreement, Recall shareholders are entitled to receive the Australian dollar equivalent of US$0.50 in cash for each outstanding share of Recall common stock (the “Cash Supplement”) as well as either (1) 0.1722 shares of our common stock for each Recall share or (2) 8.50 Australian dollars less the Australian dollar equivalent of US$0.50 in cash for each Recall share (the “Cash Election”). The Cash Election is subject to a proration mechanism that will cap the total amount of cash paid to Recall shareholders electing the Cash Election at 225,000 Australian dollars (the “Cash Election Cap”). Amounts paid to Recall shareholders that represent the Cash Supplement are excluded from the calculation of the Cash Election Cap. Assuming a sufficient number of Recall shareholders elect the Cash Election such that we pay the Cash Election Cap, we expect to issue approximately 51,000,000 shares of our common stock and, based on the exchange rate between the United States dollar and the Australian dollar as of June 30, 2015, pay approximately US$335,000 to Recall shareholders in connection with the Recall Transaction. Completion of the Scheme is subject to customary closing conditions, including among others, (i) approval by Recall shareholders of the Scheme by the requisite majorities under the Australian Corporations Act, (ii) approval by our shareholders of the issuance of shares of our common stock in connection with the Recall Transaction by the requisite majority, (iii) expiration or earlier termination of any applicable waiting period and receipt of regulatory consents, approvals and clearances, in each case, under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and under relevant antitrust/competition and foreign investment legislation in other relevant jurisdictions, (iv) the absence of any final and non-appealable order, decree or law preventing, making illegal or prohibiting the completion of the Recall Transaction, (v) approval from the New York Stock Exchange to the listing of additional shares of our common stock to be issued in the Recall Transaction, (vi) the establishment of a secondary listing on the Australian Securities Exchange (the “ASX”) to allow Recall shareholders to trade our common stock via CHESS Depository Interests on the ASX, (vii) Recall’s delivery of tax opinions in accordance and in compliance with certain tax matter agreements to which Recall is a party and (viii) no events having occurred that would have a material adverse effect on Recall or us. We expect the Recall Transaction to close in the first half of 2016.

(5) Debt (Continued)

(1) The capital stock or other equity interests of most of our United States subsidiaries, and up to 66% of the capital stock or other equity interests of our first-tier foreign subsidiaries, are pledged to secure these debt instruments, together with all intercompany obligations (including promissory notes) of subsidiaries owed to us or to one of our United States subsidiary guarantors. In addition, Iron Mountain Canada Operations ULC ("Canada Company") has pledged 66% of the capital stock of its subsidiaries, and all intercompany obligations (including promissory notes) owed to or held by it, to secure the Canadian dollar subfacility under the IMI Revolving Credit Facility (defined below). The fair value (Level 3 of fair value hierarchy described at Note 2.k.) of these debt instruments approximates the carrying value (as borrowings under these debt instruments are based on current variable market interest rates (plus a margin that is subject to change based on our consolidated leverage ratio)), as of both December 31, 2014 and June 30, 2015.

(2) The fair values (Level 1 of fair value hierarchy described at Note 2.k.) of these debt instruments are based on quoted market prices for these notes on December 31, 2014 and June 30, 2015, respectively.

(3) Collectively, the "Parent Notes." IMI is the direct obligor on the Parent Notes, which are fully and unconditionally guaranteed, on a senior or senior subordinated basis, as the case may be, by most of its direct and indirect 100% owned United States subsidiaries (the "Guarantors"). These guarantees are joint and several obligations of the Guarantors. Canada Company, Iron Mountain Europe PLC ("IME"), the Special Purpose Subsidiaries (as defined below) and the remainder of our subsidiaries do not guarantee the Parent Notes.

(4) Canada Company is the direct obligor on the CAD Notes, which are fully and unconditionally guaranteed, on a senior basis, by IMI and the Guarantors. These guarantees are joint and several obligations of IMI and the Guarantors. See Note 6 to Notes to Consolidated Financial Statements.

(5) IME is the direct obligor on the GBP Notes, which are fully and unconditionally guaranteed, on a senior basis, by IMI and the Guarantors. These guarantees are joint and several obligations of IMI and the Guarantors. See Note 6 to Notes to Consolidated Financial Statements.

(6) The Special Purpose Subsidiaries are the obligors under this program.

(7) We believe the fair value (Level 3 of fair value hierarchy described at Note 2.k.) of this debt approximates its carrying

value.

The revolving credit facilities (the "IMI Revolving Credit Facility") under our credit agreement, as amended (the "Credit Agreement"), allowed IMI and certain of its United States and foreign subsidiaries to borrow in United States dollars and (subject to sublimits) a variety of other currencies (including Canadian dollars, British pounds sterling, Euros, Brazilian reais, and Australian dollars, among other currencies) in an aggregate outstanding amount not to exceed $1,500,000. Additionally, the Credit Agreement included an option to allow us to request additional commitments of up to $500,000, in the form of term loans or through increased commitments under the IMI Revolving Credit Facility. On September 24, 2014, we exercised this option and borrowed an additional $250,000 in the form of a term loan under the Credit Agreement (the "IMI Term Loan"). Commencing on December 31, 2014, the IMI Term Loan began to amortize in quarterly installments in an amount equal to $625 per quarter, with the remaining balance due on June 27, 2016. The IMI Term Loan could be prepaid without penalty or premium, in whole or in part, at any time. The Credit Agreement included an option to allow us to request additional commitments of up to $250,000, in the form of term loans or through increased commitments under the IMI Revolving Credit Facility. On July 2, 2015, we entered into a new credit agreement, as described at Note 10, to refinance the Credit Agreement.

(5) Debt (Continued)

IMI and the Guarantors guaranteed all obligations under the Credit Agreement, and have pledged the capital stock or other equity interests of most of their United States subsidiaries, up to 66% of the capital stock or other equity interests of their first-tier foreign subsidiaries, and all intercompany obligations (including promissory notes) owed to or held by them to secure the Credit Agreement. In addition, Canada Company has pledged 66% of the capital stock of its subsidiaries, and all intercompany obligations (including promissory notes) owed to or held by it to secure the Canadian dollar subfacility under the IMI Revolving Credit Facility. The interest rate on borrowings under the Credit Agreement varied depending on our choice of interest rate and currency options, plus an applicable margin, which varied based on our consolidated leverage ratio. Additionally, the Credit Agreement required the payment of a commitment fee on the unused portion of the IMI Revolving Credit Facility, which fee ranged from between 0.3% to 0.5% based on certain financial ratios and fees associated with outstanding letters of credit. As of June 30, 2015, we had $834,753 and $248,125 of outstanding borrowings under the IMI Revolving Credit Facility and the IMI Term Loan, respectively. Of the $834,753 of outstanding borrowings under the IMI Revolving Credit Facility, $631,900 was denominated in United States dollars, 81,200 was denominated in Canadian dollars, 73,750 was denominated in Euros and 71,600 was denominated in Australian dollars. In addition, we also had various outstanding letters of credit totaling $33,835. The remaining amount available for borrowing under the IMI Revolving Credit Facility as of June 30, 2015, based on IMI's leverage ratio, the last 12 months' earnings before interest, taxes, depreciation and amortization and rent expense ("EBITDAR"), other adjustments as defined in the Credit Agreement and current external debt, was $631,412 (which amount represents the maximum availability as of such date). The average interest rate in effect under the Credit Agreement was 2.8% as of June 30, 2015. The average interest rate in effect under the IMI Revolving Credit Facility was 3.0% and ranged from 2.3% to 4.5% as of June 30, 2015 and the interest rate in effect under the IMI Term Loan as of June 30, 2015 was 2.4%.

In March 2015, we entered into a $250,000 accounts receivable securitization program (the "Accounts Receivable Securitization Program") involving several of our wholly owned subsidiaries and certain financial institutions. Under the Accounts Receivable Securitization Program, certain of our subsidiaries sell substantially all of their United States accounts receivable balances to our wholly owned special purpose entities, Iron Mountain Receivables QRS, LLC and Iron Mountain Receivables TRS, LLC (the "Special Purpose Subsidiaries"). The Special Purpose Subsidiaries use the accounts receivable balances to collateralize loans obtained from certain financial institutions. Iron Mountain Information Management, LLC retains the responsibility of servicing the accounts receivable balances pledged as collateral in this transaction and IMI provides a performance guaranty. The Accounts Receivable Securitization Program terminates on March 6, 2018, at which point all obligations become due. The maximum availability allowed is limited by eligible accounts receivable, as defined under the terms of the Accounts Receivable Securitization Program.  As of June 30, 2015, the maximum availability allowed and amount outstanding under the Accounts Receivable Securitization Program was $217,500. The interest rate in effect under the Accounts Receivable Securitization Program was 1.1% as of June 30, 2015. Commitment fees at a rate of 40 basis points are charged on amounts made available but not borrowed under the Accounts Receivable Securitization Program.

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, 2014 and June 30, 2015 are as follows:

	December 31, 2014	June 30, 2015	Maximum//Minimum Allowable
Net total lease adjusted leverage ratio	5.4	5.7	Maximum allowable of 6.5
Net secured debt lease adjusted leverage ratio	2.6	2.8	Maximum allowable of 4.0
Bond leverage ratio (not lease adjusted)	5.7	5.8	Maximum allowable of 6.5
Fixed charge coverage ratio	2.5	2.3	Minimum allowable of 1.5

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, 2014 and June 30, 2015 and for the three and six months ended June 30, 2014 and 2015 and are prepared on the same basis as the consolidated financial statements.

The Parent Notes, CAD Notes and GBP 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 and the Guarantors guarantee the CAD Notes, which were issued by Canada Company, and the GBP Notes, which were issued by IME. Canada Company and IME do not guarantee the Parent Notes. The subsidiaries that do not guarantee the Parent Notes, the CAD Notes and the GBP Notes, including IME and the Special Purpose Subsidiaries but excluding Canada Company, are referred to below as the Non-Guarantors.

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, Canada Company or a Non-Guarantor. If such a change occurs, the amount of investment in subsidiaries in the below consolidated balance sheets and equity in the earnings (losses) of subsidiaries, net of tax in the below consolidated statements of operations with respect to the relevant Parent, Guarantors, Canada Company, Non-Guarantors and Eliminations columns also would change.

In March 2015, we entered into the Accounts Receivable Securitization Program, which is described more fully in Note 5. The Special Purpose Subsidiaries, which were established in conjunction with the Accounts Receivable Securitization Program, are included in the Non-Guarantors column in the below consolidated balance sheet, consolidated statements of operations and consolidated statement of cash flows from that date forward. As a result of the Accounts Receivable Securitization Program, certain of our Guarantors sold substantially all of their United States accounts receivable balances to the Special Purpose Subsidiaries. As of June 30, 2015, this resulted in a decrease in accounts receivable, an increase in intercompany receivable and a decrease in long-term debt related to our Guarantors and a corresponding increase in accounts receivable, an increase in intercompany payable and an increase in long-term debt related to our Non-Guarantors. There was no material impact to the Guarantors and Non-Guarantors columns of the below consolidated statements of operations for the three and six months ended June 30, 2015. Additionally, the Accounts Receivable Securitization Program resulted in increased financing cash flow activity for our Non-Guarantor subsidiaries for the six months ended June 30, 2015, as the proceeds from borrowings under the Accounts Receivable Securitization Program were used to repay intercompany loans with certain of our Guarantor subsidiaries, which resulted in increased cash flows from investing activities for our Guarantor subsidiaries for the six months ended June 30, 2015.

(7) Segment Information

As a result of a realignment in senior management reporting structure during the first quarter of 2015, we modified our internal financial reporting to better align internal reporting with how we manage our business. These modifications resulted in the separation of our former International Business segment into two unique reportable operating segments, which we refer to as (1) Western European Business segment and (2) Other International Business segment. Additionally, during the first quarter of 2015, we reassessed the nature of certain costs which were previously being allocated to the North American Records and Information Management Business and North American Data Management Business segments. As a result of this reassessment, we determined that certain product management functions, which were previously being performed to solely benefit our North American operating segments, are now being performed in a manner that benefits the enterprise as a whole. Accordingly, the costs associated with these product management functions are now included within the Corporate and Other Business segment. Previously reported segment information has been restated to conform to the current period presentation.

Our five reportable operating segments are described as follows:

• North American Records and Information Management Business—storage and information management services throughout the United States and Canada, including the storage of paper documents, as well as other media such as microfilm and microfiche, master audio and videotapes, film, X‑rays and blueprints, including healthcare information services, vital records services, service and courier operations, and the collection, handling and disposal of sensitive documents for corporate customers (“Records Management”); information destruction services (“Destruction”); DMS; Fulfillment Services; and Intellectual Property Management.

• North American Data Management Business—storage and rotation of backup computer media as part of corporate disaster recovery plans throughout the United States and Canada, including service and courier operations (“Data Protection & Recovery”); server and computer backup services; digital content repository systems to house, distribute, and archive key media assets; and storage, safeguarding and electronic or physical delivery of physical media of all types, primarily for entertainment and media industry clients.

• Western European Business—Records Management, Data Protection & Recovery and DMS throughout the United Kingdom, Ireland, Norway, Austria, Belgium, France, Germany, Netherlands, Spain and Switzerland. Until December 2014, our Western European Business segment offered Destruction in the United Kingdom and Ireland.

• Other International Business—storage and information management services throughout the remaining European countries in which we operate, Latin America and Asia Pacific, including Records Management, Data Protection & Recovery and DMS. Our European operations included within the Other International Business segment provide Records Management, Data Protection & Recovery and DMS. Our Latin America operations provide Records Management, Data Protection & Recovery, Destruction and DMS throughout Argentina, Brazil, Chile, Colombia, Mexico and Peru. Our Asia Pacific operations provide Records Management, Data Protection & Recovery and DMS throughout Australia, with Records Management and Data Protection & Recovery also provided in certain cities in India, Singapore, Hong Kong‑SAR and China. Until December 2014, our Other International Business segment offered Destruction in Australia.

• Corporate and Other Business—consists of our data center business in the United States, the primary product offering of our Emerging Businesses segment, as well as costs related to executive and staff functions, including finance, human resources and information technology, which benefit the enterprise as a whole. These costs are primarily related to the general management of these functions on a corporate level and the design and development of programs, policies and procedures that are then implemented in the individual segments, with each segment bearing its own cost of implementation. Our Corporate and Other Business segment also includes stock‑based employee compensation expense associated with all Employee Stock‑Based Awards.

(7) Segment Information (Continued)

The accounting policies of the reportable segments are the same as those described in Note 2. Adjusted OIBDA for each segment is defined as operating income before depreciation, amortization, intangible impairments, (gain) loss on disposal/write-down of property, plant and equipment, net (excluding real estate), Recall Costs (as defined below) and REIT Costs (as defined below) directly attributable to the segment. Internally, we use Adjusted OIBDA as the basis for evaluating the performance of, and allocating resources to, our operating segments.

A reconciliation of Adjusted OIBDA to income (loss) from continuing operations before provision (benefit) for income taxes and (gain) loss on sale of real estate on a consolidated basis is as follows:

(1) Includes costs associated with our proposed acquisition of Recall, including costs to complete the acquisition (including advisory and professional fees) as well as costs incurred once we close the Recall Transaction to integrate Recall with our existing operations (including moving, severance, facility upgrade, REIT conversion and system upgrade costs) ("Recall Costs").

(2) Includes costs associated with our conversion to a REIT, excluding REIT compliance costs beginning January 1, 2014 which we expect to recur in future periods ("REIT Costs").

(8) Commitments and Contingencies

a.    Litigation—General

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 estimable. We record legal costs associated with loss contingencies as expenses in the period in which they are incurred. The matters described below represent our significant loss contingencies. We have evaluated each matter and, if both probable and estimable, accrued an amount that represents our estimate of any probable loss associated with such matter. In addition, we have estimated a reasonably possible range for all loss contingencies including those described below. We believe it is reasonably possible that we could incur aggregate losses in addition to amounts currently accrued for all matters up to an additional $10,000 over the next several years, of which certain amounts would be covered by insurance or indemnity arrangements.

(8) Commitments and Contingencies (Continued)

b. Italy Fire

On November 4, 2011, we experienced a fire at a facility we leased in Aprilia, Italy. The facility primarily stored archival and inactive business records for local area businesses. Despite quick response by local fire authorities, damage to the building was extensive, and the building and its contents were a total loss. Although our warehouse legal liability insurer has reserved its rights to contest coverage related to certain types of potential claims, we believe we carry adequate insurance. We have been sued by four customers, of which three of those matters have been settled. We have also received correspondence from other customers, under various theories of liabilities. We deny any liability with respect to the fire and we have referred these claims to our warehouse legal liability insurer for an appropriate response. We do not expect that this event will have a material impact on our consolidated financial condition, results of operations or cash flows. We sold our Italian operations on April 27, 2012, and we indemnified the buyers related to certain obligations and contingencies associated with the fire.

Our policy related to business interruption insurance recoveries is to record gains within other expense (income), net in our Consolidated Statements of Operations and proceeds received within cash flows from operating activities in our Consolidated Statements of Cash Flows. Such amounts are recorded in the period the cash is received. Our policy with respect to involuntary conversion of property, plant and equipment is to record any gain or loss within (gain) loss on disposal/write-down of property, plant and equipment (excluding real estate), net within operating income in our Consolidated Statements of Operations and proceeds received within cash flows from investing activities within our Consolidated Statements of Cash Flows. Losses are recorded when incurred and gains are recorded in the period when the cash received exceeds the carrying value of the related property, plant and equipment. As a result of the sale of the Italian operations, statement of operations and cash flow impacts related to the fire will be reflected as discontinued operations.

c. Argentina Fire

On February 5, 2014, we experienced a fire at a facility we own in Buenos Aires, Argentina. As a result of the quick response by local fire authorities, the fire was contained before the entire facility was destroyed and all employees were safely evacuated; however, a number of first responders lost their lives, or in some cases, were severely injured. The cause of the fire is currently being investigated. We believe we carry adequate insurance and do not expect that this event will have a material impact to our consolidated financial condition, results of operations or cash flows. Revenues from our operations at this facility represent less than 0.5% of our consolidated revenues.

(9) Stockholders' Equity Matters

In February 2010, our board of directors adopted a dividend policy under which we have paid, and in the future intend to pay, quarterly cash dividends on our common stock. Declaration and payment of future quarterly dividends is at the discretion of our board of directors.

(9) Stockholders' Equity Matters (Continued)

On September 15, 2014, we announced the declaration by our board of directors of a special distribution of $700,000 (the "Special Distribution"), payable to stockholders of record as of September 30, 2014 (the "Record Date"). The Special Distribution represented the remaining amount of our undistributed earnings and profits attributable to all taxable periods ending on or prior to December 31, 2013, which in accordance with tax rules applicable to REIT conversions, we were required to pay to our stockholders on or before December 31, 2014 in connection with our conversion to a REIT. The Special Distribution also included certain items of taxable income that we recognized in 2014, such as depreciation recapture in respect of accounting method changes commenced in our pre-REIT period as well as foreign earnings and profits recognized as dividend income. The Special Distribution followed an initial special distribution of $700,000 paid to stockholders in November 2012.

The Special Distribution was paid on November 4, 2014 (the "Payment Date") to stockholders of record as of the Record Date in a combination of common stock and cash. Stockholders had the right to elect to be paid their pro rata portion of the Special Distribution in all common stock or all cash, with the total cash payment to stockholders limited to no more than $140,000, or 20% of the total Special Distribution, not including cash paid in lieu of fractional shares. Based on stockholder elections, we paid $140,000 of the Special Distribution in cash, not including cash paid in lieu of fractional shares, with the balance paid in the form of common stock. Our shares of common stock were valued for purposes of the Special Distribution based upon the average closing price on the three trading days following October 24, 2014, or $35.55 per share, and as such, we issued approximately 15,750,000 shares of common stock in the Special Distribution. These shares impact weighted average shares outstanding from the date of issuance, and thus will impact our earnings per share data prospectively from the Payment Date.

In November 2014, our board of directors declared a distribution of $0.255 per share (the “Catch‑Up Distribution”) payable on December 15, 2014 to stockholders of record on November 28, 2014. Our board of directors declared the Catch‑Up Distribution because our cash distributions paid from January 2014 through July 2014 were declared and paid before our board of directors had determined that we would elect REIT status effective January 1, 2014 and were lower than they otherwise would have been if the final determination to elect REIT status effective January 1, 2014 had been prior to such distributions.

In fiscal year 2014 and in the first six months of 2015, our board of directors declared the following dividends:

Declaration Date	Dividend Per Share		Record Date	Total Amount		Payment Date
March 14, 2014	$	0.2700	March 25, 2014	$	51,812	April 15, 2014
May 28, 2014	0.2700		June 25, 2014	52,033		July 15, 2014
September 15, 2014	0.4750		September 25, 2014	91,993		October 15, 2014

November 17, 2014 (2)	0.2550		November 28, 2014	53,450		December 15, 2014
November 17, 2014	0.4750		December 5, 2014	99,617		December 22, 2014
February 19, 2015	0.4750		March 6, 2015	99,795		March 20, 2015
May 28, 2015	0.4750		June 12, 2015	100,119		June 26, 2015

(10) Subsequent Events

New Credit Agreement

On July 2, 2015, we entered into a new credit agreement (the "New Credit Agreement") to refinance the Credit Agreement which was scheduled to terminate on June 27, 2016. The New Credit Agreement consists of a revolving credit facility (the "New Revolving Credit Facility") and a term loan (the "New Term Loan"). The New Credit Agreement is supported by a group of 25 banks.

At the time we entered into the New Credit Agreement, we borrowed $846,231 and $250,000 under the New Revolving Credit Facility and the New Term Loan, respectively, and used such borrowings to repay outstanding balances under the Credit Agreement, including the full amount due on the IMI Term Loan. Before such repayment, there was $1,099,117 outstanding under the Credit Agreement.

The New Revolving Credit Facility, consistent with the IMI Revolving Credit Facility, enables IMI and certain of its United States and foreign subsidiaries to borrow in United States dollars and (subject to sublimits) a variety of other currencies(including Canadian dollars, British pounds sterling, Euros and Australian dollars, among other currencies) in an aggregate outstanding amount not to exceed $1,500,000. Commencing on September 30, 2015, the New Term Loan will begin to amortize in quarterly installments in an amount equal to $3,125 per quarter, with the remaining balance due on July 3, 2019. The New Credit Agreement includes an option to allow us to request additional commitments of up to $500,000, in the form of term loans or through increased commitments under the New Revolving Credit Facility, subject to the conditions as defined in the New Credit Agreement.

In addition, IMI and the Guarantors continue to guarantee all the obligations under the New Credit Agreement and, similar to the Credit Agreement, the New Credit Agreement contains 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 New Credit Agreement terminates on July 6, 2019, at which point all obligations become due, but may be extended by one year at our option, subject to the conditions set forth in the New Credit Agreement. Borrowings under the New Credit Agreement may be prepaid without penalty or premium, in whole or in part, at any time.

A debt extinguishment charge of approximately $2,300 will be recorded to other expense (income), net in the third quarter of 2015 related to the refinancing of the Credit Agreement, representing a write-off of unamortized deferred financing costs.

Overhead Optimization Plan

In the third quarter of 2015, we implemented a plan that calls for certain organizational realignments to reduce our overhead costs, particularly in our developed markets, in order to optimize our selling, general and administrative cost structure and to support investments to advance our growth strategy. As a result of these realignments, we expect to record a charge of approximately $10,000 in the third quarter of 2015. This charge primarily relates to employee severance and associated benefits.

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, 2015 should be read in conjunction with our Consolidated Financial Statements and Notes thereto for the three and six months ended June 30, 2015, included herein, and for the year ended December 31, 2014, included in our Current Report on Form 8-K filed with the United States Securities and Exchange Commission ("SEC") on May 7, 2015 (our "Current 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 in volume of records stored with us from existing customers, (3) expected 2015 consolidated revenue internal growth rate and capital expenditures, (4) expected target leverage ratio, (5) the proposed acquisition of Recall Holdings Limited ("Recall") pursuant to the Scheme Implementation Deed (the "Recall Agreement") with Recall, including our expected consideration to be paid to Recall shareholders, expected total cost of the Recall Transaction (as defined below) and expected time of closing and (6) expected cost savings associated with the Transformation Initiative (as defined below). 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 ("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 privacy issues;

• the impact of litigation or disputes that may arise in connection with incidents in which we fail to protect our customers' information;

• 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;

• our ability or inability to complete acquisitions on satisfactory terms and to integrate acquired companies efficiently;

• changes in the amount of our capital expenditures;

• 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.

In addition, with respect to the potential Recall transaction, our ability to close the proposed transaction in accordance with the terms of the Recall Agreement, or at all, is dependent on our and Recall's ability to satisfy the closing conditions set forth in the Recall Agreement, including the receipt of governmental and shareholder approvals. Other risks may adversely impact us, as described more fully under "Item 1A. Risk Factors," included herein and in our Annual Report on Form 10-K for the year ended December 31, 2014 filed with the SEC on February 27, 2015 (our "Annual Report").

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 document, as well as our other periodic reports filed with the SEC.

Non-GAAP Measures

Adjusted OIBDA

Adjusted OIBDA is defined as operating income before depreciation, amortization, intangible impairments, (gain) loss on disposal/write-down of property, plant and equipment (excluding real estate), net, Recall Costs (as defined below) and REIT Costs (as defined below). Adjusted OIBDA Margin is calculated by dividing Adjusted OIBDA by total revenues. We use multiples of current or projected Adjusted OIBDA in conjunction with our discounted cash flow models to determine our overall enterprise valuation and to evaluate acquisition targets. We believe Adjusted OIBDA and Adjusted OIBDA 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 OIBDA does not include certain items 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) (gain) loss on sale of real estate, net of tax; (3) intangible impairments; (4) Recall Costs (as defined below); (5) REIT Costs (as defined below); (6) other expense (income), net; (7) income (loss) from discontinued operations, net of tax; (8) gain (loss) on sale of discontinued operations, net of tax; and (9) net income (loss) attributable to noncontrolling interests.

Adjusted OIBDA also does not include 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 OIBDA 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 OIBDA and Adjusted OIBDA 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 or net income (loss) or cash flows from operating activities from continuing operations (as determined in accordance with GAAP).

(1) Includes costs associated with our proposed acquisition of Recall, including costs to complete the acquisition (including advisory and professional fees) as well as costs incurred once we close the Recall Transaction to integrate Recall with our existing operations (including moving, severance, facility upgrade, REIT conversion and system upgrade costs) ("Recall Costs").

(2) Includes costs associated with our conversion to a REIT, excluding REIT compliance costs beginning January 1, 2014 which we expect to recur in future periods ("REIT Costs").

Adjusted EPS

Adjusted EPS is defined as reported earnings per share from continuing operations excluding: (1) (gain) loss on disposal/write-down of property, plant and equipment (excluding real estate), net; (2) (gain) loss on sale of real estate, net of tax; (3) intangible impairments; (4) Recall Costs; (5) REIT Costs; (6) other expense (income), net; and (7) the tax impact of reconciling items and discrete tax items. We do not believe these excluded items to be indicative of our ongoing operating results, and they are not considered when we are forecasting our future results. We believe Adjusted EPS is of value to our current and potential investors when comparing our results from past, present and future periods.

Critical Accounting Policies

Our discussion and analysis of our financial condition and results of operations are based upon our 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 Current 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, 2014.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU 2014-09"). ASU 2014-09 provides additional 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, (3) licenses, (4) time value of money and (5) contract costs. Further disclosures will be required to provide a better understanding of revenue that has been recognized and revenue that is expected to be recognized in the future from existing contracts. In July 2015, the FASB deferred the effective date of ASU 2014-09 for one year, making it effective for our year beginning January 1, 2018, with early adoption permitted as of January 1, 2017. We are currently evaluating the impact ASU 2014-09 will have on our consolidated financial statements.

In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements Going Concern (Subtopic 205-40) (“ASU 2014-15”). ASU 2014-15 requires management to assess an entity’s ability to continue as a going concern by incorporating and expanding upon certain principles of current United States auditing standards. Specifically, the amendments (1) provide a definition of the term “substantial doubt”, (2) require an evaluation every reporting period, including interim periods, (3) provide principles for considering the mitigating effect of management’s plans, (4) require certain disclosures when substantial doubt is alleviated as a result of consideration of management’s plans, (5) require an express statement and other disclosures when substantial doubt is still present, and (6) require an assessment for a period of one year after the date that the financial statements are issued (or available to be issued). ASU 2014‑15 is effective for us on January 1, 2017, with early adoption permitted. We do not believe that this pronouncement will have an impact on our consolidated financial statements.

In February 2015, the FASB issued ASU No. 2015-02, Consolidation(Topic 810): Amendments to the Consolidation Analysis ("ASU 2015-02"). ASU 2015-02 affects reporting entities that are required to evaluate whether they should consolidate certain legal entities. ASU 2015-02 is effective for us on January 1, 2016, with early adoption permitted. We do not believe that this pronouncement will have an impact on our consolidated financial statements.

In April 2015, the FASB issued No. ASU 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs (“ASU 2015-03”).  The amendments in ASU 2015-03 require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts.  The recognition and measurement guidance for debt issuance costs are not affected by the amendments in ASU 2015-03.  ASU 2015‑03 is effective for us on January 1, 2016, with early adoption permitted.  We do not believe that this pronouncement will have a material impact on our consolidated financial statements.

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, 2015 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.

Proposed Recall Acquisition

On June 8, 2015, we entered into the Recall Agreement with Recall to acquire Recall (the “Recall Transaction”) by way of a recommended court approved Scheme of Arrangement (the “Scheme”). Under the terms of the Recall Agreement, Recall shareholders are entitled to receive the Australian dollar equivalent of US$0.50 in cash for each outstanding share of Recall common stock (the “Cash Supplement”) as well as either (1) 0.1722 shares of our common stock for each Recall share or (2) 8.50 Australian dollars less the Australian dollar equivalent of US$0.50 in cash for each Recall share (the “Cash Election”). The Cash Election is subject to a proration mechanism that will cap the total amount of cash paid to Recall shareholders electing the Cash Election at 225.0 million Australian dollars (the “Cash Election Cap”). Amounts paid to Recall shareholders that represent the Cash Supplement are excluded from the calculation of the Cash Election Cap. Assuming a sufficient number of Recall shareholders elect the Cash Election such that we pay the Cash Election Cap, we expect to issue approximately 51.0 million shares of our common stock and, based on the exchange rate between the United States dollar and the Australian dollar as of June 30, 2015, pay approximately US$335.0 million to Recall shareholders in connection with the Recall Transaction. Completion of the Scheme is subject to customary closing conditions, including among others, (i) approval by Recall shareholders of the Scheme by the requisite majorities under the Australian Corporations Act, (ii) approval by our shareholders of the issuance of shares of our common stock in connection with the Recall Transaction by the requisite majority, (iii) expiration or earlier termination of any applicable waiting period and receipt of regulatory consents, approvals and clearances, in each case, under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and under relevant antitrust/competition and foreign investment legislation in other relevant jurisdictions, (iv) the absence of any final and non-appealable order, decree or law preventing, making illegal or prohibiting the completion of the Recall Transaction, (v) approval from the New York Stock Exchange (the "NYSE") to the listing of additional shares of our common stock to be issued in the Recall Transaction, (vi) the establishment of a secondary listing on the Australian Securities Exchange (the “ASX”) to allow Recall shareholders to trade our common stock via CHESS Depository Interests on the ASX, (vii) Recall’s delivery of tax opinions in accordance and in compliance with certain tax matter agreements to which Recall is a party and (viii) no events having occurred that would have a material adverse effect on Recall or us. We expect the Recall Transaction to close in the first half of 2016.

Divestitures

In December 2014, we divested our secure shredding operations in Australia, Ireland and the United Kingdom (the ‘‘International Shredding Operations’’) in a stock transaction for approximately $26.2 million of cash at closing. The assets sold primarily consisted of customer contracts and certain long-lived assets. We have concluded that this divestiture did not meet the requirements to be presented as a discontinued operation. Revenues from our International Shredding Operations during the six months ended June 30, 2014 and the full year 2014 represented less than 1% of our consolidated revenues. The International Shredding Operations in Australia were previously included in the Other International Business segment and the International Shredding Operations in Ireland and the United Kingdom were previously included in the Western European Business segment.

Overhead Optimization Plan

In the third quarter of 2015, we implemented a plan that calls for certain organizational realignments to reduce our overhead costs, particularly in our developed markets, in order to optimize our selling, general and administrative cost structure and to support investments to advance our growth strategy (the “Transformation Initiative”). These realignments are designed to generate annual cost savings of approximately $50.0 million in 2016. As a result of the Transformation Initiative, we expect to record a charge of approximately $10.0 million in the third quarter of 2015. This charge primarily relates to employee severance and associated benefits.

52

General

As a result of a realignment in senior management reporting structure during the first quarter of 2015, we modified our internal financial reporting to better align internal reporting with how we manage our business. These modifications resulted in the separation of our former International Business segment into two unique reportable operating segments, which we refer to as (1) Western European Business segment and (2) Other International Business segment. Additionally, during the first quarter of 2015, we reassessed the nature of certain costs which were previously being allocated to the North American Records and Information Management Business and North American Data Management Business segments. As a result of this reassessment, we determined that certain product management functions, which were previously being performed to solely benefit our North American operating segments, are now being performed in a manner that benefits the enterprise as a whole. Accordingly, the costs associated with these product management functions are now included within the Corporate and Other Business segment. Previously reported segment information has been restated to conform to the current period presentation.

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. Service revenues include charges for related service activities, which include: (1) the handling of records, including the addition of new records, temporary removal of records from storage, refiling of removed records and the destruction of records; (2) courier operations, consisting primarily of the pickup and delivery of records upon customer request; (3) secure shredding of sensitive documents and the related sale of recycled paper, the price of which can fluctuate from period to period; (4) other services, including the scanning, imaging and document conversion services of active and inactive records, or Document Management Solutions ("DMS"), which relate to physical and digital records, and project revenues; (5) customer termination and permanent withdrawal fees; (6) data restoration projects; (7) special project work; (8) the storage, assembly and detailed reporting of customer marketing literature and delivery to sales offices, trade shows and prospective customers' sites based on current and prospective customer orders ("Fulfillment Services"); (9) consulting services; and (10) technology escrow services that protect and manage source code ("Intellectual Property Management") and other technology services and product sales (including specially designed storage containers and related supplies). Our service revenue growth has been negatively impacted by declining activity rates as stored records are becoming less active. While customers continue to store their records with us, they are less likely than they have been in the past to retrieve records for research purposes, thereby reducing service activity levels.

We recognize revenue when the following criteria are met: persuasive evidence of an arrangement exists, services have been rendered, the sales price is fixed or determinable and collectability of the resulting receivable is reasonably assured. 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. Amounts related to future storage rental or prepaid service contracts for customers where storage rental fees or services are billed in advance are accounted for as deferred revenue and recognized ratably over the period the applicable storage rental or service is provided or performed. Revenues from the sales of products, which are included as a component of service revenues, are recognized when products are shipped and title has passed to the customer. Revenues from the sales of products have historically not been significant.

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. Trends in facility occupancy costs are impacted by the total number of facilities we occupy, the mix of properties we own versus properties we occupy under operating leases, fluctuations in per square foot occupancy costs, and the levels of utilization of these properties. Trends in total wages and benefits in dollars and as a percentage of total consolidated revenue are influenced by changes in headcount and compensation levels, achievement of incentive compensation targets, workforce productivity and variability in costs associated with medical insurance and workers' compensation.

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 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 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.

53

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, building and leasehold improvements, computer systems hardware and software and buildings. Amortization relates primarily to customer relationship acquisition costs and is impacted by the nature and timing of acquisitions.

Our consolidated revenues and expenses are subject to variations caused by the net effect of foreign currency translation on revenues and expenses incurred by 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 Statement 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 2014 results at the 2015 average exchange rates.

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:

_______________________________________________________________________________

(1) Constant currency growth rates are calculated by translating the 2014 results at the 2015 average exchange rates.

(2) Our revenue internal growth rate represents the weighted average year-over-year growth rate of our revenues after removing the effects of acquisitions, divestitures and foreign currency exchange rate fluctuations. We calculate revenue internal growth in local currency for our international operations.

Consolidated storage rental revenues decreased $5.7 million, or 1.2%, to $461.2 million and $5.7 million, or 0.6%, to $920.1 million for the three and six months ended June 30, 2015, respectively, from $466.9 million and $925.8 million for the three and six months ended June 30, 2014, respectively. Consolidated storage rental internal growth and the net impact of acquisitions/divestitures were offset by unfavorable fluctuations in foreign exchange rates compared to the three and six months ended June 30, 2014. Foreign currency exchange rate fluctuations decreased our reported storage rental revenue growth rates for the three and six months ended June 30, 2015 by 5.4% and 5.0%, respectively, compared to the same prior year periods. This decrease was offset by storage rental revenue internal growth of 2.7% and 2.9% and the net impact of acquisitions/divestitures of 1.5% in each of the three and six months ended June 30, 2015, respectively, compared to the three and six months ended June 30, 2014. Our consolidated storage rental revenue internal growth in the first six months of 2015 was driven by sustained storage rental revenue internal growth of 0.2%, 5.3%, 3.6% and 11.3% in our North American Records and Information Management, North American Data Management, Western European and Other International Business segments, respectively. Global records management net volumes as of June 30, 2015 increased by 2.8% over the ending volume at June 30, 2014, supported by 9.7% volume increases in our Other International Business segment.

Consolidated service revenues decreased $21.5 million, or 6.7%, to $298.5 million and $42.3 million, or 6.7%, to $588.9 million for the three and six months ended June 30, 2015, respectively, from $320.0 million and $631.2 million for the three and six months ended June 30, 2014, respectively. Foreign currency exchange rate fluctuations decreased our reported total service revenues by 6.0% and 5.6% for the three and six months ended June 30, 2015, respectively, compared to the same prior year periods. Service revenue internal growth was flat for the three months ended June 30, 2015 compared to the three months ended June 30, 2014. Service revenue internal growth was negative 0.5% for the six months ended June 30, 2015 compared to the six months ended June 30, 2014. The negative service revenue internal growth for the six months ended June 30, 2015 reflects reduced retrieval/re-file activity and a related decrease in transportation revenues within our North American Records and Information Management Business segment, as well as continued declines in service revenue activity levels in our North American Data Management Business segment as the storage business becomes more archival in nature. In the North American Records and Information Management Business segment, the decline in service activities has begun to stabilize in recent periods, while service revenue declines in the North American Data Management Business segment are reflecting more recent reductions in service activity levels. Net acquisitions/divestitures decreased reported service revenues by 0.6% in the six months ended June 30, 2015 compared to the six months ended June 30, 2014, primarily due to a $12.6 million reduction in consolidated service revenue associated with the disposition of our International Shredding Operations.

56

For the reasons stated above, our consolidated revenues decreased $27.2 million, or 3.5%, to $759.7 million and $48.0 million, or 3.1%, to $1,509.0 million for the three and six months ended June 30, 2015, respectively, from $786.9 million and $1,557.0 million for the three and six months ended June 30, 2014, respectively. For the three and six months ended June 30, 2015, foreign currency exchange rate fluctuations decreased our reported consolidated revenues by 5.7% and 5.3%, respectively, compared to the same prior year periods, primarily due to the weakening of the Australian dollar, Brazilian real, British pound sterling, Canadian dollar and the Euro against the United States dollar, based on an analysis of weighted average rates for the comparable periods. This decrease was partially offset by consolidated revenue internal growth of 1.6% and 1.5 % and the net impact of acquisitions/divestitures of 0.6% and 0.7% in the three and six months ended June 30, 2015, respectively, compared to the three and six months ended June 30, 2014, respectively.

Storage Rental Revenue	2.3	%	1.3	%	1.4	%	1.6	%	2.2	%	3.5	%	3.0	%	2.7	%

We expect our consolidated revenue internal growth rate for 2015 to be approximately 0% to 2%. During the past eight quarters, our storage rental revenue internal growth rate has ranged between 1.3% and 3.5%. Storage rental revenue internal growth rates have been relatively stable over the past two fiscal years, averaging between 2.1% and 2.2% for full-year 2013 and 2014. At various points in the economic cycle, storage rental revenue internal growth may be influenced by changes in pricing and volume. Recently, we initiated sales force programs focused on increasing volume through new sales and improved customer retention. In addition, we are working on enhancing our pricing strategy through implementing a statistical-based approach, which enables customized pricing based on customer profiles and needs. Within our international portfolio, the Western European Business segment is generating consistent low-to-mid single-digit storage rental revenue internal growth, while the Other International Business segment is producing strong double-digit storage rental revenue internal growth by capturing the first-time outsourcing trends for physical records storage and management in those markets. The internal growth rate for service revenue is inherently more volatile than the storage rental revenue internal growth rate 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 reflects reduced retrieval/re-file activity and a related decrease in transportation revenues within our North American Records and Information Management Business segment, 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.

Labor

Labor expense increased to 21.6% of consolidated revenues in the six months ended June 30, 2015 compared to 21.5% in the six months ended June 30, 2014. Labor costs were favorably impacted by 6.4 percentage points due to currency rate changes during the six months ended June 30, 2015. Labor expense for the three months ended June 30, 2015 increased by 5.7% on a constant dollar basis compared to the three months ended June 30, 2014. This increase was primarily due to a $5.3 million increase in labor costs in our Other International Business segment, primarily associated with the impact of recent acquisitions and a $3.1 million increase in medical and workers' compensation costs, primarily associated with our North American Records and Information Management Business segment. Labor expense for the six months ended June 30, 2015 increased by 3.6% on a constant dollar basis compared to the six months ended June 30, 2014. This increase was primarily due to a $10.3 million increase in labor costs in our Other International Business segment, primarily associated with the impact of recent acquisitions, partially offset by a $1.5 million reduction in restructuring costs, primarily associated with our North American Records and Information Management Business segment.

Facilities

Facilities costs decreased to 14.2% of consolidated revenues in the six months ended June 30, 2015 compared to 14.3% in the six months ended June 30, 2014. Facilities costs were favorably impacted by 5.5 percentage points due to currency rate changes during the six months ended June 30, 2015. Rent expense increased by $2.9 million on a constant dollar basis for the six months ended June 30, 2015 compared to the six months ended June 30, 2014, primarily driven by increased costs in our Other International Business segment. Other facilities costs increased by $1.6 million on a constant dollar basis for the six months ended June 30, 2015 compared to the six months ended June 30, 2014, primarily due to higher property taxes and common area charges of $2.3 million and building maintenance and security costs of $3.6 million, partially offset by a decrease in insurance costs of $4.1 million primarily associated with a fire at one of our facilities in Buenos Aires, Argentina in February 2014.

58

Transportation

Transportation costs decreased by $5.6 million on a constant dollar basis in the six months ended June 30, 2015 compared to the six months ended June 30, 2014, primarily as a result of decreased fuel and insurance costs of $3.9 million and $1.4 million, respectively. Transportation costs were favorably impacted by 4.4 percentage points due to currency rate changes during the six months ended June 30, 2015.

Product Cost of Sales and Other

Product cost of sales and other, which includes cartons, media and other service, storage and supply costs, is highly correlated to service revenue streams, particularly project revenues. For the six months ended June 30, 2015, product cost of sales and other increased by $1.2 million compared to the six months ended June 30, 2014 on an actual basis, primarily associated with higher special project costs within our North American Data Management Business segment. These costs were favorably impacted by 8.4 percentage points due to currency rate changes during the six months ended June 30, 2015.

General and Administrative

General and administrative expenses decreased to 16.2% of consolidated revenues during the six months ended June 30, 2015 compared to 16.8% in the six months ended June 30, 2014. On a constant dollar basis, general and administrative expenses decreased by $4.8 million during the six months ended June 30, 2015 compared to the six months ended June 30, 2014, primarily as a result of a $14.0 million decrease in REIT Costs and a $2.0 million decrease in restructuring costs, partially offset by a $5.7 million increase in Recall Costs, a $2.7 million increase in general and administrative expenses associated with our Other International Business segment, as well as an increase in legal reserves primarily associated with our Western European Business segment. General and administrative expenses were favorably impacted by 4.7 percentage points due to currency rate changes during the six months ended June 30, 2015.

59

Sales, Marketing & Account Management

Sales, marketing and account management expenses increased to 7.1% of consolidated revenues during the six months ended June 30, 2015 compared to 6.8% in the six months ended June 30, 2014. On a constant dollar basis, sales, marketing and account management expenses during the six months ended June 30, 2015 increased by $5.5 million compared to the six months ended June 30, 2014, primarily due to an increase in marketing expenses of $2.4 million, primarily associated with our North American Data Management Business segment, as well as an increase in sales commissions of $2.0 million. Sales, marketing and account management expenses were favorably impacted by 4.7 percentage points due to currency rate changes during the six months ended June 30, 2015.

Information Technology

On a constant dollar basis, information technology expenses increased $1.4 million during the six months ended June 30, 2015 compared to the six months ended June 30, 2014, primarily due to increased compensation expenses of $1.0 million. Information technology expenses were favorably impacted by 4.5 percentage points due to currency rate changes during the six months ended June 30, 2015.

Bad Debt Expense

Consolidated bad debt expense for the six months ended June 30, 2015 increased $0.9 million to $10.4 million (0.7% of consolidated revenues) from $9.5 million (0.6% of consolidated revenues) in the six months ended June 30, 2014. 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.

Depreciation, Amortization, and (Gain) Loss on Disposal/Write-down of Property, Plant and Equipment (Excluding Real Estate), Net

Depreciation expense increased $7.6 million on a constant dollar basis for the six months ended June 30, 2015 compared to the six months ended June 30, 2014 primarily due to the increased depreciation of property, plant and equipment acquired through business combinations.

Amortization expense increased $0.5 million on a constant dollar basis for the six months ended June 30, 2015 compared to the six months ended June 30, 2014 primarily due to the increased amortization of customer relationship intangible assets acquired through business combinations.

As a result of our conversion to a REIT and in accordance with SEC rules applicable to REITs, we no longer report (gain) loss on the sale of real estate as a component of operating income, but we report it as a component of income (loss) from continuing operations. We report the (gain) loss on sale of property, plant and equipment (excluding real estate), along with any impairment, write-downs or involuntary conversions related to real estate, as a component of operating income. Previously reported amounts have been reclassified to conform to this presentation.

Consolidated loss on disposal/write-down of property, plant and equipment (excluding real estate), net was $0.8 million for the six months ended June 30, 2015 and consisted primarily of the write-off of certain property associated with our North American Records and Information Management Business segment. Consolidated loss on disposal/write-down of property, plant and equipment (excluding real estate), net was $1.0 million for the six months ended June 30, 2014 and consisted primarily of losses associated with the write-off of certain software associated with our North American Records and Information Management Business segment.

OPERATING INCOME AND ADJUSTED OIBDA

As a result of the foregoing factors, consolidated operating income decreased $17.8 million, or 12.1%, to $129.5 million (17.0% of consolidated revenues) for the three months ended June 30, 2015 from $147.3 million (18.7% of consolidated revenues) for the three months ended June 30, 2014 and consolidated Adjusted OIBDA decreased $18.6 million, or 7.7%, to $223.2 million (29.4% of consolidated revenues) for the three months ended June 30, 2015 from $241.8 million (30.7% of consolidated revenues) for the three months ended June 30, 2014. Consolidated operating income decreased $5.5 million, or 2.0%, to $274.4 million (18.2% of consolidated revenues) for the six months ended June 30, 2015 from $279.9 million (18.0% of consolidated revenues) for the six months ended June 30, 2014 and consolidated Adjusted OIBDA decreased $15.9 million, or 3.4%, to $454.4 million (30.1% of consolidated revenues) for the six months ended June 30, 2015 from $470.4 million (30.2% of consolidated revenues) for the six months ended June 30, 2014.

OTHER EXPENSES, NET

Interest Expense, Net

Consolidated interest expense, net increased $3.9 million to $66.1 million (8.7% of consolidated revenues) and $6.5 million to $131.0 million (8.7% of consolidated revenues) for the three and six months ended June 30, 2015, respectively, from $62.2 million (7.9% of consolidated revenues) and $124.5 million (8.0% of consolidated revenues) for the three and six months ended June 30, 2014, respectively, primarily due to the issuance in September 2014 of 400.0 million British pounds sterling in aggregate principal of the 6¹/₈% Senior Notes due 2022 (the "GBP Notes") by Iron Mountain Europe PLC ("IME"), partially offset by the redemption of $306.0 million aggregate principal outstanding of our 8³/₈% Senior Subordinated Notes due 2021 in December 2014, as well as the redemption of 150.0 million British pounds sterling of the 7¹/₄% GBP Senior Subordinated Notes due 2014 in January 2014. Our weighted average interest rate was 5.4% and 5.8% at June 30, 2015 and 2014, respectively.

	$	(4,838	)	$	2,004	$	6,842	$	479		$	24,353	$	23,874

We recorded net foreign currency transaction losses of $23.9 million in the six months ended June 30, 2015, based on period-end exchange rates. These losses resulted primarily from changes in the exchange rate of each of the Argentine peso, Brazilian real, Ukrainian hryvnia and Euro against the United States dollar compared to December 31, 2014, as these currencies relate to our intercompany balances with and between our Latin American and European subsidiaries, as well as Euro forward contracts. These losses were partially offset by gains primarily from changes in the exchange rate of the Russian ruble as it relates to our intercompany balances with and between our European subsidiaries, and Euro denominated bonds issued by Iron Mountain Incorporated ("IMI").

We recorded net foreign currency transaction losses of $2.1 million in the six months ended June 30, 2014, based on period-end exchange rates. These losses resulted primarily from changes in the exchange rate of each of the Argentine peso, Russian ruble and Ukrainian hryvnia against the United States dollar compared to December 31, 2013, as these currencies relate to our intercompany balances with and between our Latin American and European subsidiaries, losses on Australian dollar and British pound sterling forward contracts and losses on British pound sterling borrowings on our revolving credit facility. These losses were partially offset by gains primarily from changes in the exchange rate of each of the Brazilian real, British pound sterling and Australian dollar, as these currencies relate to our intercompany balances with and between our Latin American, European and Australian subsidiaries and Euro denominated bonds issued by IMI.

Other, net in the six months ended June 30, 2015 consisted primarily of $0.6 million related to the write-down of certain investments. Other, net in the six months ended June 30, 2014 consisted primarily of $0.9 million of royalty income and $0.4 million of gains associated with a deferred compensation plan.

Provision for Income Taxes

Our effective tax rates for the three and six months ended June 30, 2015 were 12.1% and 19.6%, respectively. The primary reconciling items between the federal statutory rate of 35% and our overall effective tax rate in the three and six months ended June 30, 2015 were the benefit derived from the dividends paid deduction, differences in the rates of tax at which our foreign earnings are subject, including foreign exchange gains and losses in different jurisdictions with different tax rates and state income taxes (net of federal tax benefit).

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

61

As a result of our REIT conversion, we recorded a net tax benefit of $230.1 million and $212.2 million during the three and six months ended June 30, 2014, respectively, for the revaluation of certain deferred tax assets and liabilities and other income taxes associated with the REIT conversion. The other primary reconciling items between the federal statutory rate of 35% and our overall effective tax rate in the three and six months ended June 30, 2014 were a $36.1 million increase in our tax provision recognized in the second quarter of 2014 associated with incremental federal and state income taxes and foreign withholding taxes on earnings of our foreign subsidiaries no longer considered permanently invested and other net tax benefit related to the REIT conversion of $18.8 million and $33.8 million, respectively, primarily related to the dividends paid deduction.

We provide for income taxes during interim periods based on our estimate of the effective tax rate for the year. Discrete items and changes in our estimate of the annual effective tax rate are recorded in the period they occur. Our effective tax rate is subject to variability in the future due to, among other items: (1) changes in the mix of income between our qualified REIT subsidiaries and our TRSs, as well as between 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. We are subject to income taxes in the United States and numerous foreign jurisdictions. We are subject to examination by various tax authorities in jurisdictions in which we have business operations or a taxable presence. We regularly assess the likelihood of additional assessments by tax authorities and provide for these matters as appropriate. Although we believe our tax estimates are appropriate, the final determination of tax audits and any related litigation could result in changes in our estimates.

Gain on Sale of Real Estate, Net of Tax

Consolidated gain on sale of real estate for the six months ended June 30, 2014 was $7.5 million, net of tax of $2.0 million associated with the sale of two buildings in the United Kingdom.

INCOME FROM CONTINUING OPERATIONS

As a result of the foregoing factors, consolidated income from continuing operations for the three months ended June 30, 2015 decreased $218.7 million, or 80.2%, to $54.0 million (7.1% of consolidated revenues) from $272.7 million (34.7% of consolidated revenues) for the three months ended June 30, 2014. Consolidated income from continuing operations for the six months ended June 30, 2015 decreased $219.7 million, or 69.6%, to $95.7 million (6.3% of consolidated revenues) from $315.4 million (20.3% of consolidated revenues) for the six months ended June 30, 2014.

INCOME (LOSS) FROM DISCONTINUED OPERATIONS, NET OF TAX

Loss from discontinued operations, net of tax was $0.9 million for the six months ended June 30, 2014, primarily related to legal reserves.

NONCONTROLLING INTERESTS

For the three and six months ended June 30, 2015, net income attributable to noncontrolling interests resulted in a decrease in net income attributable to IMI of $0.7 million and $1.3 million, respectively. For the three and six months ended June 30, 2014, net income attributable to noncontrolling interests resulted in a decrease in net income attributable to IMI of $0.7 million and $1.2 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.

Segment Analysis (in thousands)

As a result of a realignment in senior management reporting structure during the first quarter of 2015, we modified our internal financial reporting to better align internal reporting with how we manage our business. These modifications resulted in the separation of our former International Business segment into two unique reportable operating segments, which we refer to as (1) Western European Business segment and (2) Other International Business segment. Additionally, during the first quarter of 2015, we reassessed the nature of certain costs which were previously being allocated to the North American Records and Information Management Business and North American Data Management Business segments. As a result of this reassessment, we determined that certain product management functions, which were previously being performed to solely benefit our North American operating segments, are now being performed in a manner that benefits the enterprise as a whole. Accordingly, the costs associated with these product management functions are now included within the Corporate and Other Business segment. Previously reported segment information has been restated to conform to the current period presentation.

Our five reportable operating segments are described as follows:

• North American Records and Information Management Business—storage and information management services throughout the United States and Canada, including the storage of paper documents, as well as other media such as microfilm and microfiche, master audio and videotapes, film, X-rays and blueprints, including healthcare information services, vital records services, service and courier operations, and the collection, handling and disposal of sensitive documents for corporate customers (“Records Management”); information destruction services (“Destruction”); DMS; Fulfillment Services; and Intellectual Property Management.

• North American Data Management Business—storage and rotation of backup computer media as part of corporate disaster recovery plans throughout the United States and Canada, including service and courier operations (“Data Protection & Recovery”); server and computer backup services; digital content repository systems to house, distribute, and archive key media assets; and storage, safeguarding and electronic or physical delivery of physical media of all types, primarily for entertainment and media industry clients.

• Western European Business—Records Management, Data Protection & Recovery and DMS throughout the United Kingdom, Ireland, Norway, Austria, Belgium, France, Germany, Netherlands, Spain and Switzerland. Until December 2014, our Western European Business segment offered Destruction in the United Kingdom and Ireland.

• Other International Business—storage and information management services throughout the remaining European countries in which we operate, Latin America and Asia Pacific, including Records Management, Data Protection & Recovery and DMS. Our European operations included within the Other International Business segment provide Records Management, Data Protection & Recovery and DMS. Our Latin America operations provide Records Management, Data Protection & Recovery, Destruction and DMS throughout Argentina, Brazil, Chile, Colombia, Mexico and Peru. Our Asia Pacific operations provide Records Management, Data Protection & Recovery and DMS throughout Australia, with Records Management and Data Protection & Recovery also provided in certain cities in India, Singapore, Hong Kong‑SAR and China. Until December 2014, our Other International Business segment offered Destruction in Australia.

• Corporate and Other Business—consists of our data center business in the United States, the primary product offering of our Emerging Businesses segment, as well as costs related to executive and staff functions, including finance, human resources and information technology, which benefit the enterprise as a whole. These costs are primarily related to the general management of these functions on a corporate level and the design and development of programs, policies and procedures that are then implemented in the individual segments, with each segment bearing its own cost of implementation. Our Corporate and Other Business segment also includes stock-based employee compensation expense associated with all stock options, restricted stock, restricted stock units, performance units and shares of stock issued under our employee stock purchase plan.

For the three and six months ended June 30, 2015, reported revenue in our North American Records and Information Management Business segment decreased 0.7% and 0.8%, respectively, compared to the three and six months ended June 30, 2014, primarily due to negative internal growth and foreign currency exchange rate fluctuations. For both the three and six months ended June 30, 2015, foreign currency exchange rate fluctuations decreased our reported revenues for the North American Records and Information Management Business segment by 1.3% compared to the same prior year periods due to the weakening of the Canadian dollar against the United States dollar. Negative internal growth of 0.6% and 0.5% in the three and six months ended June 30, 2015, respectively, was primarily the result of negative service revenue internal growth of 1.3% and 1.6% in the three and six months ended June 30, 2015, respectively, resulting from reduced retrieval/re-file activity and a related decrease in transportation revenues. Net acquisitions/divestitures increased reported revenue in our North American Records and Information Management Business segment by 1.2% and 1.0% in the three and six months ended June 30, 2015, respectively, compared to the three and six months ended June 30, 2014. Adjusted OIBDA as a percentage of segment revenue increased 180 basis points during the six months ended June 30, 2015, compared to the six months ended June 30, 2014, primarily driven by a $5.8 million decrease in professional fees, a $3.9 million decrease in fuel and insurance costs, a $2.0 million decrease in rent expense, a $2.2 million decrease in restructuring costs, as well as a decrease in sales, marketing and account management costs.

During the three and six months ended June 30, 2015, reported revenue in our North American Data Management Business segment increased 2.1% and 1.3%, respectively, compared to the three and six months ended June 30, 2014, primarily due to internal growth of 2.7% and 1.9% in the three and six months ended June 30, 2015, respectively. The internal revenue growth was primarily attributable to storage rental revenue internal growth of 5.3% for both the three and six months ended June 30, 2015, respectively, primarily related to volume increases, partially offset by negative service revenue internal growth of 1.7% and 3.8% in the three and six months ended June 30, 2015, respectively, which was due to declines in service revenue activity levels as the business becomes more archival in nature. For both the three and six months ended June 30, 2015, foreign currency exchange rate fluctuations decreased our reported revenues for the North American Data Management Business segment by 0.8% compared to the same prior year periods due to the weakening of the Canadian dollar against the United States dollar. Adjusted OIBDA as a percentage of segment revenue decreased 690 basis points during the six months ended June 30, 2015 compared to the six months ended June 30, 2014, primarily due to increased overhead expenses of $8.4 million, primarily associated with higher sales, marketing and account management expenses and, to a lesser extent, reduced gross profit related to a decline in service revenues without a corresponding decrease in costs.

During the three and six months ended June 30, 2015, reported revenue in our Western European Business segment decreased 15.4% and 14.7%, respectively, compared to the three and six months ended June 30, 2014, primarily as a result of fluctuations in foreign currency exchange rates. Foreign currency fluctuations resulted in decreased revenue in the three and six months ended June 30, 2015, respectively, as measured in United States dollars, of approximately 12.6% and 12.2%, as compared to the same prior year periods, due to the weakening of the British pound sterling and the Euro against the United States dollar. Internal revenue growth for the three and six months ended June 30, 2015 was 0.1% and 0.6%, respectively, supported by 3.5% and 3.6% storage rental revenue internal growth in the three and six months ended June 30, 2015, respectively. Net acquisitions/divestitures decreased reported revenue in our Western European Business segment by 3.1% in the six months ended June 30, 2015, compared to the six months ended June 30, 2014, primarily due to an $8.1 million reduction in reported service revenues associated with the disposition of our shredding operations in the United Kingdom and Ireland in December 2014. Adjusted OIBDA as a percentage of segment revenue decreased 80 basis points during the six months ended June 30, 2015 compared to the six months ended June 30, 2014 primarily due to an increase in legal reserves.

During the three and six months ended June 30, 2015, reported revenues in our Other International Business segment decreased 7.6% and 5.4%, respectively, compared to the three and six months ended June 30, 2014, primarily as a result of fluctuations in foreign currency exchange rates. Foreign currency fluctuations in the three and six months ended June 30, 2015 resulted in decreased revenue, as measured in United States dollars, of approximately 21.2% and 19.4%, respectively, as compared to the same prior year periods, primarily due to the weakening of the Australian dollar, Brazilian real and Euro against the United States dollar. Internal revenue growth for the three and six months ended June 30, 2015 was 12.3% and 10.9%, respectively, supported by 11.5% and 11.3% storage rental revenue internal growth for the three and six months ended June 30, 2015, respectively. Net acquisitions/divestitures increased reported revenue in our Other International Business segment by 1.3% and 3.1% in the three and six months ended June 30, 2015, respectively, compared to the three and six months ended June 30, 2014, as the impact of our recent acquisitions in Brazil, Turkey and Poland were partially offset by a $2.3 million and a $4.5 million decrease in reported service revenues for the three and six months ended June 30, 2015, respectively, associated with the disposition of our Australian shredding operations in December 2014. Adjusted OIBDA as a percentage of segment revenue decreased 110 basis points during the six months ended June 30, 2015 compared to the six months ended June 30, 2014, primarily as a result of changes in foreign currency exchange rates.

During the six months ended June 30, 2015, Adjusted OIBDA in the Corporate and Other Business segment as a percentage of consolidated revenue decreased primarily due to an increase in overhead expenses of $4.4 million, primarily related to sales, marketing and account management expenses, partially offset by a decrease in facilities costs of $2.2 million, primarily associated with a fire at one of our facilities in Buenos Aires, Argentina in February 2014.

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,

	2014			2015
Cash flows from operating activities	$	195,601		$	179,738
Cash flows from investing activities	(234,713		)	(150,612		)
Cash flows from financing activities	59,827			(35,469		)
Cash and cash equivalents at the end of period	145,343			117,098

Net cash provided by operating activities was $179.7 million for the six months ended June 30, 2015 compared to $195.6 million for the six months ended June 30, 2014. The 8.1% period over period decrease resulted primarily from an increase in cash used in working capital of $43.4 million, primarily related to the timing of operating accounts payable payments and accruals, partially offset by an increase in net income, including non-cash charges and realized foreign exchange losses, of $27.5 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. These expenditures are included in the cash flows from investing activities. The nature of our capital expenditures has evolved over time along with the nature of our business. Our capital goes to support business-line growth and our ongoing operations, but we also expend capital to support the development and improvement of products and services and projects designed to increase our profitability. These expenditures are generally discretionary in nature. Cash paid for our capital expenditures, cash paid for acquisitions (net of cash acquired) and additions to customer acquisition costs during the six months ended June 30, 2015 amounted to $139.4 million, $21.7 million and $24.2 million, respectively. For the six months ended June 30, 2015, these expenditures were primarily funded with cash flows provided by borrowings under the IMI revolving credit facility (discussed below) and the Accounts Receivable Securitization Program (defined below). Excluding capital expenditures associated with potential future acquisitions and additional real estate purchases above our plan, we expect our capital expenditures to be approximately $330.0 million to $360.0 million in the year ending December 31, 2015 (inclusive of approximately $25.0 million in planned real estate purchases).

Net cash used in financing activities was $35.5 million for the six months ended June 30, 2015. During the six months ended June 30, 2015, we received net proceeds of $160.0 million of debt (primarily associated with the Accounts Receivable Securitization Program and the IMI revolving credit facility (discussed below)) as well as $9.5 million from proceeds from the exercise of stock options and the employee stock purchase plan. We used the proceeds from these transactions for the payment of dividends in the amount of $203.2 million on our common stock.

Dividends and Distributions

In February 2010, our board of directors adopted a dividend policy under which we have paid, and in the future intend to pay, quarterly cash dividends on our common stock. Declaration and payment of future quarterly dividends is at the discretion of our board of directors.

On September 15, 2014, we announced the declaration by our board of directors of a special distribution of $700.0 million (the "Special Distribution"), payable to stockholders of record as of September 30, 2014 (the "Record Date"). The Special Distribution represented the remaining amount of our undistributed earnings and profits attributable to all taxable periods ending on or prior to December 31, 2013, which in accordance with tax rules applicable to REIT conversions, we were required to pay to our stockholders on or before December 31, 2014 in connection with our conversion to a REIT. The Special Distribution also included certain items of taxable income that we recognized in 2014, such as depreciation recapture in respect of accounting method changes commenced in our pre-REIT period as well as foreign earnings and profits recognized as dividend income. The Special Distribution followed an initial special distribution of $700.0 million paid to stockholders in November 2012.

69

The Special Distribution was paid on November 4, 2014 (the ‘‘Payment Date’’) to stockholders of record as of the Record Date in a combination of common stock and cash. Stockholders had the right to elect to be paid their pro rata portion of the Special Distribution in all common stock or all cash, with the total cash payment to stockholders limited to no more than $140.0 million, or 20% of the total Special Distribution, not including cash paid in lieu of fractional shares. Based on stockholder elections, we paid $140.0 million of the Special Distribution in cash, not including cash paid in lieu of fractional

shares, with the balance paid in the form of common stock. Our shares of common stock were valued for purposes of the Special Distribution based upon the average closing price on the three trading days following October 24, 2014, or $35.55 per share, and as such, we issued approximately 15.8 million shares of common stock in the Special Distribution. These shares impact weighted average shares outstanding from the date of issuance, and thus will impact our earnings per share data prospectively from the Payment Date.

In November 2014, our board of directors declared a distribution of $0.255 per share (the ‘‘Catch-Up Distribution’’) payable on December 15, 2014 to stockholders of record on November 28, 2014. Our board of directors declared the Catch-Up Distribution because our cash distributions paid from January 2014 through July 2014 were declared and paid before our board of directors had determined that we would elect REIT status effective January 1, 2014 and were lower than they otherwise would have been if the final determination to elect REIT status effective January 1, 2014 had been prior to such distributions.

In fiscal year 2014 and in the first six months of 2015, our board of directors declared the following dividends:

Declaration Date	Dividend Per Share		Record Date	Total Amount (in thousands)		Payment Date
March 14, 2014	$	0.2700	March 25, 2014	$	51,812	April 15, 2014

Financial Instruments and Debt

Financial instruments that potentially subject us to credit risk consist principally of cash and cash equivalents (including money market funds and time deposits) and accounts receivable. The only significant concentrations of liquid investments as of June 30, 2015 relate to cash and cash equivalents held on deposit with three global banks, all of which we consider to be large, highly-rated investment-grade institutions. As per our risk management investment policy, we limit exposure to concentration of credit risk by limiting the amount invested in any one mutual fund to a maximum of $50.0 million or in any one financial institution to a maximum of $75.0 million. As of June 30, 2015, our cash and cash equivalents balance was $117.1 million, including time deposits amounting to $20.8 million.

(1) The capital stock or other equity interests of most of our United States subsidiaries, and up to 66% of the capital stock or other equity interests of our first-tier foreign subsidiaries, are pledged to secure these debt instruments, together with all intercompany obligations (including promissory notes) of subsidiaries owed to us or to one of our United States subsidiary guarantors. In addition, Iron Mountain Canada Operations ULC ("Canada Company") has pledged 66% of the capital stock of its subsidiaries, and all intercompany obligations (including promissory notes) owed to or held by it, to secure the Canadian dollar subfacility under the IMI Revolving Credit Facility (defined below).

(2) Collectively, the "Parent Notes." IMI is the direct obligor on the Parent Notes, which are fully and unconditionally guaranteed, on a senior or senior subordinated basis, as the case may be, by most of its direct and indirect 100% owned United States subsidiaries (the "Guarantors"). These guarantees are joint and several obligations of the Guarantors. Canada Company, IME, the Special Purpose Subsidiaries (as defined below) and the remainder of our subsidiaries do not guarantee the Parent Notes.

(3) Canada Company is the direct obligor on the CAD Notes, which are fully and unconditionally guaranteed, on a senior basis, by IMI and the Guarantors. These guarantees are joint and several obligations of IMI and the Guarantors. See Note 6 to Notes to Consolidated Financial Statements included in this Quarterly Report.

(4) IME is the direct obligor on the GBP Notes, which are fully and unconditionally guaranteed, on a senior basis, by IMI and the Guarantors. These guarantees are joint and several obligations of IMI and the Guarantors. See Note 6 to Notes to Consolidated Financial Statements included in this Quarterly Report.

(5) The Special Purpose Subsidiaries are the obligors under this program.

The revolving credit facilities (the "IMI Revolving Credit Facility") under our credit agreement, as amended (the "Credit Agreement"), allowed IMI and certain of its United States and foreign subsidiaries to borrow in United States dollars and (subject to sublimits) a variety of other currencies (including Canadian dollars, British pounds sterling, Euros, Brazilian reais, and Australian dollars, among other currencies) in an aggregate outstanding amount not to exceed $1.5 billion. Additionally, the Credit Agreement included an option to allow us to request additional commitments of up to $500.0 million, in the form of term loans or through increased commitments under the IMI Revolving Credit Facility. On September 24, 2014, we exercised this option and borrowed an additional $250.0 million in the form of a term loan under the Credit Agreement (the "IMI Term Loan"). Commencing on December 31, 2014, the IMI Term Loan began to amortize in quarterly installments in an amount equal to $0.6 million per quarter, with the remaining balance due on June 27, 2016. The IMI Term Loan could be prepaid without penalty or premium, in whole or in part, at any time. The Credit Agreement included an option to allow us to request additional commitments of up to $250.0 million, in the form of term loans or through increased commitments under the IMI Revolving Credit Facility.

71

IMI and the Guarantors guaranteed all obligations under the Credit Agreement, and have pledged the capital stock or other equity interests of most of their United States subsidiaries, up to 66% of the capital stock or other equity interests of their first-tier foreign subsidiaries, and all intercompany obligations (including promissory notes) owed to or held by them to secure the Credit Agreement. In addition, Canada Company has pledged 66% of the capital stock of its subsidiaries, and all intercompany obligations (including promissory notes) owed to or held by it to secure the Canadian dollar subfacility under the IMI Revolving Credit Facility. The interest rate on borrowings under the Credit Agreement varied depending on our choice of interest rate and currency options, plus an applicable margin, which varied based on our consolidated leverage ratio. Additionally, the Credit Agreement required the payment of a commitment fee on the unused portion of the IMI Revolving Credit Facility, which fee ranged from between 0.3% to 0.5% based on certain financial ratios and fees associated with outstanding letters of credit. As of June 30, 2015, we had $834.8 million and $248.1 million of outstanding borrowings under the IMI Revolving Credit Facility and the IMI Term Loan, respectively. Of the $834.8 million of outstanding borrowings under the IMI Revolving Credit Facility, $631.9 million was denominated in United States dollars, 81.2 million was denominated in Canadian dollars, 73.8 million was denominated in Euros and 71.6 million was denominated in Australian dollars. In addition, we also had various outstanding letters of credit totaling $33.8 million. The remaining amount available for borrowing under the IMI Revolving Credit Facility as of June 30, 2015, based on IMI's leverage ratio, the last 12 months' earnings before interest, taxes, depreciation and amortization and rent expense ("EBITDAR"), other adjustments as defined in the Credit Agreement and current external debt, was $631.4 million (which amount represents the maximum availability as of such date). The average interest rate in effect under the Credit Agreement was 2.8% as of June 30, 2015. The average interest rate in effect under the IMI Revolving Credit Facility was 3.0% and ranged from 2.3% to 4.5% as of June 30, 2015 and the interest rate in effect under the IMI Term Loan as of June 30, 2015 was 2.4%.

On July 2, 2015, we entered into a new credit agreement (the "New Credit Agreement") to refinance the Credit Agreement which was scheduled to terminate on June 27, 2016. The New Credit Agreement consists of a revolving credit facility (the "New Revolving Credit Facility") and a term loan (the "New Term Loan"). The New Credit Agreement is supported by a group of 25 banks.

At the time we entered into the New Credit Agreement, we borrowed $846.2 million and $250.0 million under the New Revolving Credit Facility and the New Term Loan, respectively, and used such borrowings to repay outstanding balances under the Credit Agreement, including the full amount due on the IMI Term Loan. Before such repayment, there was $1,099.1 billion outstanding under the Credit Agreement.

The New Revolving Credit Facility, consistent with the IMI Revolving Credit Facility, enables IMI and certain of its United States and foreign subsidiaries to borrow in United States dollars and (subject to sublimits) a variety of other currencies(including Canadian dollars, British pounds sterling, Euros and Australian dollars, among other currencies) in an aggregate outstanding amount not to exceed $1.5 billion. Commencing on September 30, 2015, the New Term Loan will begin to amortize in quarterly installments in an amount equal to $3.1 million per quarter, with the remaining balance due on July 3, 2019. The New Credit Agreement includes an option to allow us to request additional commitments of up to $500.0 million, in the form of term loans or through increased commitments under the New Revolving Credit Facility, subject to the conditions as defined in the New Credit Agreement.

In addition, IMI and the Guarantors continue to guarantee all the obligations under the New Credit Agreement and, similar to the Credit Agreement, the New Credit Agreement contains 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 New Credit Agreement terminates on July 6, 2019, at which point all obligations become due, but may be extended by one year at our option, subject to the conditions set forth in the New Credit Agreement. Borrowings under the New Credit Agreement may be prepaid without penalty or premium, in whole or in part, at any time.

72

In March 2015, we entered into a $250.0 million accounts receivable securitization program (the "Accounts Receivable Securitization Program") involving several of our wholly owned subsidiaries and certain financial institutions. Under the Accounts Receivable Securitization Program, certain of our subsidiaries sell substantially all of their United States accounts receivable balances to our wholly owned special purpose entities, Iron Mountain Receivables QRS, LLC and Iron Mountain Receivables TRS, LLC (the "Special Purpose Subsidiaries"). The Special Purpose Subsidiaries use the accounts receivable balances to collateralize loans obtained from certain financial institutions. Iron Mountain Information Management, LLC retains the responsibility of servicing the accounts receivable balances pledged as collateral in this transaction and IMI provides a performance guaranty. The Accounts Receivable Securitization Program terminates on March 6, 2018, at which point all obligations become due. The maximum availability allowed is limited by eligible accounts receivable, as defined under the terms of the Accounts Receivable Securitization Program.  As of June 30, 2015, the maximum availability allowed and amount outstanding under the Accounts Receivable Securitization Program was $217.5 million. The interest rate in effect under the Accounts Receivable Securitization Program was 1.1% as of June 30, 2015. Commitment fees at a rate of 40 basis points are charged on amounts made available but not borrowed under the Accounts Receivable Securitization Program.

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, 2014 and June 30, 2015 are as follows:

	December 31, 2014	June 30, 2015	Maximum//Minimum Allowable
Net total lease adjusted leverage ratio	5.4	5.7	Maximum allowable of 6.5
Net secured debt lease adjusted leverage ratio	2.6	2.8	Maximum allowable of 4.0
Bond leverage ratio (not lease adjusted)	5.7	5.8	Maximum allowable of 6.5
Fixed charge coverage ratio	2.5	2.3	Minimum allowable of 1.5

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

Commitment fees and letters of credit fees, which are based on the unused balances under the IMI Revolving Credit Facility and the Accounts Receivable Securitization Program for the three and six months ended June 30, 2014 and 2015, respectively, are as follows (in thousands):

	Three Months Ended June 30,				Six Months Ended June 30,
	2014		2015		2014		2015
Commitment fees and letters of credit fees	$	509	$	991	$	1,167	$	1,858

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.

Acquisitions

In the first six months of 2015, in order to enhance our existing operations in the United States, United Kingdom, Canada, Australia and Chile, we completed six acquisitions for total consideration of approximately $18.4 million. These acquisitions included four storage and records management companies, one storage and data management company and one personal storage company. The individual purchase prices of these acquisitions ranged from approximately $2.3 million to approximately $5.5 million.

73

Proposed Recall Acquisition

On June 8, 2015, we entered into the Recall Agreement with Recall to acquire the Recall Transaction by way of the Scheme. Under the terms of the Recall Agreement, Recall shareholders are entitled to receive the Cash Supplement as well as either (1) 0.1722 shares of our common stock for each Recall share or (2) the Cash Election. The Cash Election is subject to the Cash Election Cap. Amounts paid to Recall shareholders that represent the Cash Supplement are excluded from the calculation of the Cash Election Cap. Assuming a sufficient number of Recall shareholders elect the Cash Election such that we pay the Cash Election Cap, we expect to issue approximately 51.0 million shares of our common stock and, based on the exchange rate between the United States dollar and the Australian dollar as of June 30, 2015, pay approximately US$335.0 million to Recall shareholders in connection with the Recall Transaction. Completion of the Scheme is subject to customary closing conditions, including among others, (i) approval by Recall shareholders of the Scheme by the requisite majorities under the Australian Corporations Act, (ii) approval by our shareholders of the issuance of shares of our common stock in connection with the Recall Transaction by the requisite majority, (iii) expiration or earlier termination of any applicable waiting period and receipt of regulatory consents, approvals and clearances, in each case, under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and under relevant antitrust/competition and foreign investment legislation in other relevant jurisdictions, (iv) the absence of any final and non-appealable order, decree or law preventing, making illegal or prohibiting the completion of the Recall Transaction, (v) approval from the NYSE to the listing of additional shares of our common stock to be issued in the Recall Transaction, (vi) the establishment of a secondary listing on the ASX to allow Recall shareholders to trade our common stock via CHESS Depository Interests on the ASX, (vii) Recall’s delivery of tax opinions in accordance and in compliance with certain tax matter agreements to which Recall is a party and (viii) no events having occurred that would have a material adverse effect on Recall or us. We expect the Recall Transaction to close in the first half of 2016.

There are significant costs associated with the Recall Transaction, including (i) costs to complete the acquisition (including advisory and professional fees) as well as costs incurred once we close the Recall Transaction to integrate Recall with our existing operations (including moving, severance, facility upgrade, REIT conversion and system upgrade costs), (ii) the cash components of the purchase price noted above and (iii) the payoff of outstanding borrowings under Recall’s existing revolving credit facility upon closing of the transaction. We expect the cost of the Recall Transaction (including costs to complete the acquisition, the cash components of the purchase price and the payoff of Recall's revolving credit facility, but excluding integration costs) to be approximately $1.0 billion. We intend to fund these costs through a combination of cash on hand, availability under our New Credit Agreement and, as necessary, public or private debt financing.

Contractual Obligations

We expect to meet our cash flow requirements for the next twelve months from cash generated from operations, existing cash, cash equivalents, borrowings under the New Credit Agreement and other financings, which may include senior or senior subordinated notes, secured credit facilities, securitizations and mortgage or capital lease financings, and the issuance of equity. We expect to meet our long-term cash flow requirements using the same means described above. We are highly leveraged. While we expect to continue to be highly leveraged for the foreseeable future, as a REIT we expect our long-term capital allocation strategy will naturally shift toward increased use of equity to support lower leverage, though our leverage has increased, in the short- term, to fund the costs of our conversion to a REIT.

Net Operating Losses

We have federal net operating loss carryforwards, which expire from 2021 through 2033, of $88.0 million ($0, tax effected) at June 30, 2015 to reduce future federal taxable income, on which no federal tax benefit is expected to be realized. We have state net operating loss carryforwards, which expire from 2015 through 2033, of $74.4 million ($0.1 million, tax effected) at June 30, 2015 to reduce future state taxable income. We have assets for foreign net operating losses of $78.4 million, with various expiration dates (and in some cases no expiration date), subject to a valuation allowance of approximately 64%.

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 through increased operating efficiencies, the negotiation of favorable long-term real estate leases and customer contracts 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, summarized and communicated 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, 2015 (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 have been no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) under the Securities Act of 1934) during the quarter ended June 30, 2015 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Part II. Other Information

Item 1A. Risk Factors

Our businesses face many risks. You should carefully consider the risks and uncertainties described below and under “Forward Looking Statements” in this Quarterly Report on Form 10‑Q, as well as in Part I-Item 1A under the heading “Risk Factors” and the information contained under the heading “Cautionary Note Regarding Forward‑Looking Statements” in our Annual Report, and the other information included or incorporated by reference in this Quarterly Report on Form 10‑Q and in other documents that we file with the SEC from time to time before making an investment decision regarding our securities. If any of the events or circumstances described in the following risks actually occurs, our businesses, financial condition or results of operations could suffer and the trading price of our debt or equity securities could decline.

The information presented below updates and should be read in connection with the risk factors and information disclosed in our Annual Report. In particular, these risk factors are intended to be read in connection with the risk factors under the heading "Risk Factors - Acquisition and Expansion Risks” in our Annual Report.

Risks Related to theRecall Transaction (Pre-Closing)

We will incur significant transaction and combination-related costs in connection with the Recall Transaction.

We and Recall expect to incur significant costs associated with the Recall Transaction and combining the operations of the two companies. Our fees and expenses related to the Recall Transaction include financial advisors’ fees, filing fees, legal and accounting fees, soliciting fees and regulatory fees, some of which will be paid regardless of whether the Recall Transaction is completed. Furthermore, we will incur costs associated with combining the operations of the two companies. However, it is difficult to predict the amount of these costs before we begin the integration process. We may incur additional unanticipated costs as a consequence of difficulties arising from efforts to integrate the companies.

75

We will need additional financing, which may not be available on favorable terms, if at all, in order to consummate the Recall Transaction.

We currently anticipate that we will need to raise additional debt financing to consummate the Recall Transaction. Such additional financing may not be available on favorable terms, if at all. If we are unable to obtain sufficient financing and consummate the Scheme, we may be subject to significant monetary or other damages under the Recall Agreement.

The Recall Agreement limits our ability to pursue alternatives to the Recall Transaction, and in certain instances requires payment of a reimbursement fee, which could deter a third party from proposing an alternative transaction to the Recall Transaction.

While the Recall Agreement is in effect, subject to certain limited exceptions, we are prohibited from soliciting, initiating, encouraging or entering into certain transactions, such as a merger, sale of assets or other business combination, with any third party. As a result of these limitations, we may lose opportunities to enter into a more favorable transaction than the Recall Transaction.

Moreover, under specified circumstances, we could be required to pay Recall a reimbursement fee of 25.5 million Australian dollars in connection with the termination of the Recall Agreement. The reimbursement fee could deter a third party from proposing an alternative to the Recall Transaction.

The Recall Transaction is subject to conditions to closing that could result in the Recall Transaction being delayed or not completed and the Recall Agreement can be terminated in certain circumstances, each of which could negatively impact the price of our common stock and our future business and operations.

Consummation of the Recall Transaction is subject to conditions, including, among others:

• the approval by the Recall shareholders of the Recall Agreement and the other transactions contemplated by the Recall Agreement;

• the approval by our stockholders of the issuance of our common stock to Recall shareholders as part of the Scheme consideration;

• the absence of any law, order or injunction that would prohibit, restrain or make illegal the Recall Transaction;

• the receipt of regulatory approvals;

• the approval for listing on the NYSE of our common stock to be issued in the Recall Transaction and the establishment of a secondary listing on the ASX to allow shareholders of Recall to trade our common stock via CHESS Depository Interests on the ASX;

• the accuracy of the representations and warranties and compliance with the respective covenants of the parties, subject to specified materiality qualifiers; and

• no events having occurred that would have a material adverse effect on Recall or us.

In addition, we and Recall each has the right, in certain circumstances, to terminate the Recall Agreement. If the Recall Agreement is terminated or any of the conditions to closing are not satisfied and, where permissible, not waived, the Recall Transaction will not be completed. Failure to complete the Recall Transaction or any delay in the completion of the Recall Transaction or any uncertainty about the completion of the Recall Transaction may adversely affect the price of our common stock or have an adverse impact on our future business and operations.

If the Recall Transaction is not completed, our ongoing business may be adversely affected and, without realizing any of the benefits of having completed the Recall Transaction, we would be subject to a number of risks, including the following:

• negative reactions from the financial markets;

• incurring and paying significant expenses in connection with the Recall Transaction, such as financial advisors’ fees, filing fees, legal and accounting fees, soliciting fees, regulatory fees and other related expenses;

• paying a reimbursement fee of 25.5 million Australian dollars if the Recall Agreement is terminated in certain circumstances; and

• paying a reimbursement fee of 76.5 million Australian dollars if the Recall Agreement is terminated due to our being unable to obtain the necessary antitrust/competition approvals required to consummate the Recall Transaction.

In addition, we could be subject to litigation related to any failure to complete the Recall Transaction or seeking to require us to perform our obligations under the Recall Agreement.

76

The exchange ratio is fixed and will not be adjusted in the event of any change in either Recall’s share price or our stock price.

Subject to the terms and conditions set forth in the Recall Agreement, after the effective time of the Scheme and upon the completion of the Recall Transaction, each outstanding ordinary share of Recall will be transferred to us in exchange for the Cash Supplement and either (1) 0.1722 shares of our common stock or (2) the Cash Election, subject to the Cash Election Cap. The exchange ratio is fixed and will not be adjusted for changes in the market price of either Recall shares or our shares. Changes in the price of our shares prior to completion of the Scheme may affect the market value that holders of Recall shares will receive on the date of the effective time for the Scheme. Share price changes may result from a variety of factors (many of which are beyond our or Recall’s control).

If the share price of our common stock increases before the closing of the Recall Transaction, Recall shareholders will receive shares of our common stock that have a market value that is greater than the current market value of such shares. Alternatively, if the share price of our common stock decreases before the closing of the Recall Transaction, Recall shareholders will receive shares of our common stock that have a market value that is less than the current market value of such shares. Therefore, because the exchange ratio is fixed, prior to the closing of the Recall Transaction, our stockholders and Recall shareholders cannot be sure of the market value of the share consideration that will be paid to Recall shareholders upon completion of the Recall Transaction.

Obtaining required governmental and court approvals necessary to satisfy closing conditions may delay or prevent completion of the Recall Transaction.

Completion of the Recall Transaction is conditioned upon the receipt of certain governmental authorizations, consents, orders or other approvals, including approvals, clearances, filings or expiration or termination of waiting periods required in relation to the Recall Transaction under antitrust laws of Australia, the United States and the United Kingdom. The Scheme must also be approved by the Federal Court of Australia, Sydney Registry. No assurance can be given that the approvals will be obtained, and, even if such approvals are obtained, no assurance can be given as to the terms, conditions and timing of the approvals or that they will satisfy the terms of the Recall Agreement.

Risks Related to theRecall Transaction (Post-Closing)

The failure to integrate successfully our and Recall’s businesses in the expected time frame would adversely affect our future results.

The success of the Recall Transaction will depend, in large part, on our ability to realize the anticipated benefits, including cost savings, from combining our and Recall’s businesses. To realize these anticipated benefits, our and Recall’s businesses must be successfully integrated. This integration will be complex and time-consuming. The failure to integrate successfully and to manage successfully the challenges presented by the integration process may result in us not fully achieving the anticipated benefits of the Recall Transaction.

Potential difficulties that may be encountered in the integration process include the following:

• challenges and difficulties associated with managing the larger, more complex, combined business;

• conforming standards, controls, procedures and policies, business cultures and compensation structures between the entities;

• integrating personnel from the two entities while maintaining focus on developing, producing and delivering consistent, high quality services;

• consolidating corporate and administrative infrastructures;

• coordinating geographically dispersed organizations;

• potential unknown liabilities and unforeseen expenses, delays or regulatory conditions associated with the Recall Transaction;

• performance shortfalls at one or both of the entities as a result of the diversion of management’s attention caused by completing the Recall Transaction and integrating the entities’ operations; and

• our ability to deliver on our strategy going forward.

77

The integration of Recall will subject us to liabilities that may exist at Recall.

Our integration with Recall may pose special risks, including one-time write-offs or restructuring charges, unanticipated costs, and the loss of key employees. There can be no assurance that our integration with Recall will be accomplished effectively or in a timely manner. In addition, our integration with Recall will subject us to liabilities that may exist at Recall, some of which may be unknown. Although we and our advisors have conducted due diligence on the operations of Recall, there can be no guarantee that we are aware of any and all liabilities of Recall. These liabilities, and any additional risks and uncertainties related to the Recall Transaction not currently known to us or that we may currently deem immaterial, could negatively impact our future business, financial condition and results of operations.

The price of our common stock and our results of operations after the Recall Transaction may be affected by factors different from those currently affecting the price of our common stock and our results of operations.

Recall’s business is different in certain ways from ours, and our results of operations, as well as the price of our common stock after the Recall Transaction, may be affected by factors different from those currently affecting our results of operations and the price of our common stock. The price of our common stock may fluctuate significantly following the Recall Transaction, including as a result of factors over which we and Recall have no control.

The market price of our common stock may decline as a result of the Recall Transaction.

The market price of our common stock may decline as a result of the Recall Transaction if we do not achieve the perceived benefits of the Recall Transaction as rapidly or to the extent anticipated by financial or industry analysts or if the effect of the Recall Transaction on our financial results is not consistent with the expectations of financial or industry analysts. Current stockholders may not wish to continue to invest in us if the Recall Transaction is consummated or for other reasons may wish to dispose of some or all of their shares of our common stock. If, following the consummation of the Recall Transaction, there is selling pressure on our common stock that exceeds demand at the market price, the price of our common stock could decline. In addition, if the Recall Transaction is completed, the Recall shareholders will own a significant percentage of the issued and outstanding shares of common stock of the combined company, and they may determine not to hold their shares of our common stock following the Recall Transaction, which may result in additional pressure on the price of our common stock.

We would incur adverse tax consequences if the combined company following the Recall Transaction failed to qualify as a REIT for United States federal income tax purposes.

We believe that, following the Recall Transaction, we will integrate Recall’s assets and operations in a manner that will allow us to timely satisfy the REIT income, asset, and distribution tests applicable to us. However, if we fail to do so, we could jeopardize or lose our qualification for taxation as a REIT, particularly if we were ineligible to utilize relief provisions set forth in the Internal Revenue Code of 1986, as amended. For any taxable year that we fail to qualify for taxation as a REIT, we would not be allowed a deduction for distributions to our stockholders in computing our taxable income, and thus be subject to United States federal and state income tax at the regular corporate rates on all of our United States federal and state taxable income in the manner of a regular corporation. Those corporate level taxes would reduce the amount of cash available for distribution to our stockholders or for reinvestment or other purposes, and would adversely affect our earnings. As a result, our failure to qualify for taxation as a REIT during any taxable year could have a material adverse effect upon us and our stockholders. Furthermore, unless prescribed relief provisions apply, we would not be eligible to elect REIT status again until the fifth taxable year that begins after the first year for which we failed to qualify as a REIT. Finally, even if we are able to utilize relief provisions and thereby avoid disqualification for taxation as a REIT, relief provisions typically involve paying a penalty tax in proportion to the severity and duration of the noncompliance with REIT requirements, and thus these penalty taxes could be significant in the context of noncompliance stemming from a transaction as large as the Recall Transaction.

78

We will guarantee certain obligations of Recall to Brambles relating to Brambles’ prior demerger transaction.

On December 18, 2013, Brambles Limited, an Australian corporation ("Brambles"), implemented a demerger transaction by way of a distribution of shares of Recall to Brambles’ shareholders (the “Demerger”). Prior to and in connection with the Demerger, Brambles spun off certain of its United States and Canadian subsidiaries, directly or indirectly, to Recall. Such spin-offs were intended to be tax-free or tax-deferred under United States and Canadian tax laws, respectively, and Brambles obtained rulings from the United States Internal Revenue Service (with respect to the United States spin-off) and the Canada Revenue Agency (with respect to the Canadian spin-off), as well as opinions of its tax advisors, to such effect. However, the tax-free status of the spin-off of such United States subsidiaries could be adversely affected under certain circumstances if a 50% or greater interest in such United States subsidiaries were acquired as part of a plan or series of related transactions that included such spin-off. Similarly, the tax-deferred status of the spin-off of the Canadian subsidiaries could be adversely affected under certain circumstances if control of such subsidiaries were acquired as part of a series of transactions or events that included such spin-off.

In connection with the Demerger, Recall agreed to indemnify Brambles and certain of its affiliates for taxes to the extent that actions by Recall (e.g., an acquisition of Recall shares) resulted in the United States spin-off or the Canadian spin-off described above failing to qualify as tax-free or tax-deferred for United States or Canadian tax purposes, respectively. In addition, Recall agreed, among other things, that it would not, within two years of the 2013 spin-offs, enter into a proposed acquisition transaction, merger or consolidation (with respect to the United States spin-off) or take any action that could reasonably be expected to jeopardize, directly or indirectly, any of the conclusions reached in the Canadian tax ruling or opinion, without obtaining either a supplemental tax ruling from the relevant taxing authority, the consent of Brambles or an opinion of a tax advisor, acceptable to Brambles in its reasonable discretion, that such transaction should not result in the spin-offs failing to be tax-free under United States federal income tax law or Canadian tax law, respectively. Recall has obtained or intends to obtain such tax opinions, based on, among other things, representations and warranties made by Recall and us. Such opinions, once accepted by Brambles, do not affect Recall’s obligation to indemnify Brambles for an adverse impact on the tax-free status of such prior spin-offs. The delivery of those opinions is a condition to our obligation to consummate the Recall Transaction.

We have agreed, contingent on the consummation of the Recall Transaction, to guarantee the foregoing indemnification obligations of Recall. Consistent with the foregoing tax opinions, we believe that the Recall Transaction is not part of a plan or series of related transactions, or part of a series of transactions or events, that included the United States spin-off or the Canadian spin-off, respectively. However, if the United States Internal Revenue Service or the Canadian Revenue Agency were to prevail in asserting a contrary view, we and Recall would be liable for the resulting taxes, which could be material.

Due diligence related risks.

Before executing the Recall Agreement, we and Recall undertook a period of mutual due diligence for the purpose of negotiating the terms of the Scheme. Although we and Recall decided to proceed with the Scheme following that due diligence exercise, there is a risk that the due diligence undertaken was insufficient or failed to identify key issues. Furthermore, after implementation of the Scheme, we will be subject to any unknown liabilities of Recall which could have an adverse effect on our performance and financial condition.

Following the Recall Transaction, our exposure to foreign exchange translation risk will be increased.

As disclosed in “Risk Factors - Operational Risks” in our Annual Report, we currently are subject to foreign exchange translation risk because we conduct business operations in several foreign countries through our foreign subsidiaries or affiliates, which operate in their respective local currencies. Recall conducts a significant portion of its operations outside of the United States through foreign subsidiaries or affiliates, which also operate in their respective local currencies. Therefore, following the completion of the Recall Transaction, our international operations will account for a more significant portion of our overall operations than they do presently. Because our financial statements will continue to be presented in United States dollars subsequent to the Recall Transaction, the local currencies will be translated into United States dollars at the applicable exchange rates for inclusion in our consolidated financial statements. The results of operations of, and certain of our intercompany balances associated with, our international storage and information management services businesses will continue to be exposed to foreign exchange rate fluctuations, and due to the Recall Transaction, our exposure to exchange rate fluctuations will increase. Upon translation, operating results may differ materially from expectations, and significant shifts in foreign currencies can impact our short-term results, as well as our long-term forecasts and targets. In addition, because we intend to distribute 100% of our REIT taxable income to our stockholders, and any exchange rate fluctuations may negatively impact our REIT taxable income, our distribution amounts may fluctuate as a result of exchange rate fluctuations.

79

The Recall Transaction, if completed, will dilute the ownership position of our current stockholders.

If the Recall Transaction is completed, the Recall shareholders will own a significant percentage of the issued and outstanding shares of common stock of the combined company. Consequently, our current stockholders will own a smaller proportion of our common stock than the proportion of our common stock they owned before the Recall Transaction and, as a result, they will have less influence on our management and policies following the Recall Transaction than they now have on our management and policies.

Our and Recall’s business relationships may be subject to disruption due to uncertainty associated with the Recall Transaction, which could have an adverse effect on our and Recall’s results of operations, cash flows and financial position and, following the completion of the Recall Transaction, the combined company.

Parties with which we and Recall do business may experience uncertainty associated with the Recall Transaction, including with respect to current or future business relationships with us, Recall or the combined company.  Our and Recall’s relationships may be subject to disruption as customers, suppliers and other persons with whom we and Recall have a business relationship may delay or defer certain business decisions or might decide to seek to terminate, change or renegotiate their relationships with us or Recall, as applicable, or consider entering into business relationships with parties other than us or Recall. These disruptions could have an adverse effect on the results of operations, cash flows and financial position of us, Recall or the combined company following the completion of the Recall Transaction, including an adverse effect on our ability to realize the expected synergies and other benefits of the Recall Transaction. The risk, and adverse effect, of any disruption could be exacerbated by a delay in the completion of the Recall Transaction or the termination of the Recall Agreement.

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

We did not sell any unregistered securities during the three months ended June 30, 2015, nor did we repurchase any shares of our common stock during the three months ended June 30, 2015.

______________________________________________________________________________

(1) The capital stock or other equity interests of most of our United States subsidiaries, and up to 66% of the capital stock or other equity interests of our first-tier foreign subsidiaries, are pledged to secure these debt instruments, together with all intercompany obligations (including promissory notes) of subsidiaries owed to us or to one of our United States subsidiary guarantors. In addition, Iron Mountain Canada Operations ULC ("Canada Company") has pledged 66% of the capital stock of its subsidiaries, and all intercompany obligations (including promissory notes) owed to or held by it, to secure the Canadian dollar subfacility under the IMI Revolving Credit Facility (defined below). The fair value (Level 3 of fair value hierarchy described at Note 2.k.) of these debt instruments approximates the carrying value (as borrowings under these debt instruments are based on current variable market interest rates (plus a margin that is subject to change based on our consolidated leverage ratio)), as of both December 31, 2014 and June 30, 2015.

(2) The fair values (Level 1 of fair value hierarchy described at Note 2.k.) of these debt instruments are based on quoted market prices for these notes on December 31, 2014 and June 30, 2015, respectively.

(3) Collectively, the "Parent Notes." IMI is the direct obligor on the Parent Notes, which are fully and unconditionally guaranteed, on a senior or senior subordinated basis, as the case may be, by most of its direct and indirect 100% owned United States subsidiaries (the "Guarantors"). These guarantees are joint and several obligations of the Guarantors. Canada Company, Iron Mountain Europe PLC ("IME"), the Special Purpose Subsidiaries (as defined below) and the remainder of our subsidiaries do not guarantee the Parent Notes.

(4) Canada Company is the direct obligor on the CAD Notes, which are fully and unconditionally guaranteed, on a senior basis, by IMI and the Guarantors. These guarantees are joint and several obligations of IMI and the Guarantors. See Note 6 to Notes to Consolidated Financial Statements.

(5) IME is the direct obligor on the GBP Notes, which are fully and unconditionally guaranteed, on a senior basis, by IMI and the Guarantors. These guarantees are joint and several obligations of IMI and the Guarantors. See Note 6 to Notes to Consolidated Financial Statements.

(6) The Special Purpose Subsidiaries are the obligors under this program.

(7) We believe the fair value (Level 3 of fair value hierarchy described at Note 2.k.) of this debt approximates its carrying

value.

Segment Information

Segment Reporting [Abstract]

Segment Information

As a result of a realignment in senior management reporting structure during the first quarter of 2015, we modified our internal financial reporting to better align internal reporting with how we manage our business. These modifications resulted in the separation of our former International Business segment into two unique reportable operating segments, which we refer to as (1) Western European Business segment and (2) Other International Business segment. Additionally, during the first quarter of 2015, we reassessed the nature of certain costs which were previously being allocated to the North American Records and Information Management Business and North American Data Management Business segments. As a result of this reassessment, we determined that certain product management functions, which were previously being performed to solely benefit our North American operating segments, are now being performed in a manner that benefits the enterprise as a whole. Accordingly, the costs associated with these product management functions are now included within the Corporate and Other Business segment. Previously reported segment information has been restated to conform to the current period presentation.

Our five reportable operating segments are described as follows:

• North American Records and Information Management Business—storage and information management services throughout the United States and Canada, including the storage of paper documents, as well as other media such as microfilm and microfiche, master audio and videotapes, film, X‑rays and blueprints, including healthcare information services, vital records services, service and courier operations, and the collection, handling and disposal of sensitive documents for corporate customers (“Records Management”); information destruction services (“Destruction”); DMS; Fulfillment Services; and Intellectual Property Management.

• North American Data Management Business—storage and rotation of backup computer media as part of corporate disaster recovery plans throughout the United States and Canada, including service and courier operations (“Data Protection & Recovery”); server and computer backup services; digital content repository systems to house, distribute, and archive key media assets; and storage, safeguarding and electronic or physical delivery of physical media of all types, primarily for entertainment and media industry clients.

• Western European Business—Records Management, Data Protection & Recovery and DMS throughout the United Kingdom, Ireland, Norway, Austria, Belgium, France, Germany, Netherlands, Spain and Switzerland. Until December 2014, our Western European Business segment offered Destruction in the United Kingdom and Ireland.

• Other International Business—storage and information management services throughout the remaining European countries in which we operate, Latin America and Asia Pacific, including Records Management, Data Protection & Recovery and DMS. Our European operations included within the Other International Business segment provide Records Management, Data Protection & Recovery and DMS. Our Latin America operations provide Records Management, Data Protection & Recovery, Destruction and DMS throughout Argentina, Brazil, Chile, Colombia, Mexico and Peru. Our Asia Pacific operations provide Records Management, Data Protection & Recovery and DMS throughout Australia, with Records Management and Data Protection & Recovery also provided in certain cities in India, Singapore, Hong Kong‑SAR and China. Until December 2014, our Other International Business segment offered Destruction in Australia.

• Corporate and Other Business—consists of our data center business in the United States, the primary product offering of our Emerging Businesses segment, as well as costs related to executive and staff functions, including finance, human resources and information technology, which benefit the enterprise as a whole. These costs are primarily related to the general management of these functions on a corporate level and the design and development of programs, policies and procedures that are then implemented in the individual segments, with each segment bearing its own cost of implementation. Our Corporate and Other Business segment also includes stock‑based employee compensation expense associated with all Employee Stock‑Based Awards.

An analysis of our business segment information and reconciliation to the accompanying Consolidated Financial Statements is as follows:

(1) Excludes all intercompany receivables or payables and investment in subsidiary balances.

The accounting policies of the reportable segments are the same as those described in Note 2. Adjusted OIBDA for each segment is defined as operating income before depreciation, amortization, intangible impairments, (gain) loss on disposal/write-down of property, plant and equipment, net (excluding real estate), Recall Costs (as defined below) and REIT Costs (as defined below) directly attributable to the segment. Internally, we use Adjusted OIBDA as the basis for evaluating the performance of, and allocating resources to, our operating segments.

A reconciliation of Adjusted OIBDA to income (loss) from continuing operations before provision (benefit) for income taxes and (gain) loss on sale of real estate on a consolidated basis is as follows:

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

Commitments and Contingencies

a.    Litigation—General

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 estimable. We record legal costs associated with loss contingencies as expenses in the period in which they are incurred. The matters described below represent our significant loss contingencies. We have evaluated each matter and, if both probable and estimable, accrued an amount that represents our estimate of any probable loss associated with such matter. In addition, we have estimated a reasonably possible range for all loss contingencies including those described below. We believe it is reasonably possible that we could incur aggregate losses in addition to amounts currently accrued for all matters up to an additional $10,000 over the next several years, of which certain amounts would be covered by insurance or indemnity arrangements.

b. Italy Fire

On November 4, 2011, we experienced a fire at a facility we leased in Aprilia, Italy. The facility primarily stored archival and inactive business records for local area businesses. Despite quick response by local fire authorities, damage to the building was extensive, and the building and its contents were a total loss. Although our warehouse legal liability insurer has reserved its rights to contest coverage related to certain types of potential claims, we believe we carry adequate insurance. We have been sued by four customers, of which three of those matters have been settled. We have also received correspondence from other customers, under various theories of liabilities. We deny any liability with respect to the fire and we have referred these claims to our warehouse legal liability insurer for an appropriate response. We do not expect that this event will have a material impact on our consolidated financial condition, results of operations or cash flows. We sold our Italian operations on April 27, 2012, and we indemnified the buyers related to certain obligations and contingencies associated with the fire.

Our policy related to business interruption insurance recoveries is to record gains within other expense (income), net in our Consolidated Statements of Operations and proceeds received within cash flows from operating activities in our Consolidated Statements of Cash Flows. Such amounts are recorded in the period the cash is received. Our policy with respect to involuntary conversion of property, plant and equipment is to record any gain or loss within (gain) loss on disposal/write-down of property, plant and equipment (excluding real estate), net within operating income in our Consolidated Statements of Operations and proceeds received within cash flows from investing activities within our Consolidated Statements of Cash Flows. Losses are recorded when incurred and gains are recorded in the period when the cash received exceeds the carrying value of the related property, plant and equipment. As a result of the sale of the Italian operations, statement of operations and cash flow impacts related to the fire will be reflected as discontinued operations.

c. Argentina Fire

On February 5, 2014, we experienced a fire at a facility we own in Buenos Aires, Argentina. As a result of the quick response by local fire authorities, the fire was contained before the entire facility was destroyed and all employees were safely evacuated; however, a number of first responders lost their lives, or in some cases, were severely injured. The cause of the fire is currently being investigated. We believe we carry adequate insurance and do not expect that this event will have a material impact to our consolidated financial condition, results of operations or cash flows. Revenues from our operations at this facility represent less than 0.5% of our consolidated revenues.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

a.    Principles of Consolidation

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

b.    Cash, Cash Equivalents and Restricted Cash

Cash and cash equivalents include cash on hand and cash invested in highly liquid short-term securities, which have remaining maturities at the date of purchase of less than 90 days. Cash and cash equivalents are carried at cost, which approximates fair value.

At December 31, 2014, we had $33,860 of restricted cash associated with a collateral trust agreement with our insurance carrier related to our workers' compensation self-insurance program included in current assets on our Consolidated Balance Sheet. The restricted cash consisted primarily of United States Treasuries. We had no restricted cash at June 30, 2015.

c.    Foreign Currency

Local currencies are the functional currencies for our operations outside the United States, with the exception of certain foreign holding companies and our financing centers in Switzerland, whose functional currency is the United States dollar. In those instances where the local currency is the functional currency, assets and liabilities are translated at period-end exchange rates, and revenues and expenses are translated at average exchange rates for the applicable period. Resulting translation adjustments are reflected in the accumulated other comprehensive items, net component of Iron Mountain Incorporated Stockholders' Equity and Noncontrolling Interests in the accompanying Consolidated Balance Sheets. The gain or loss on foreign currency transactions, calculated as the difference between the historical exchange rate and the exchange rate at the applicable measurement date, including those related to (1) our previously outstanding 7¹/₄% GBP Senior Subordinated Notes due 2014 (the "7¹/₄% Notes"), (2) our 6³/₄% Euro Senior Subordinated Notes due 2018 (the "6³/₄% Notes"), (3) borrowings in certain foreign currencies under our revolving credit facility and (4) certain foreign currency denominated intercompany obligations of our foreign subsidiaries to us and between our foreign subsidiaries, which are not considered permanently invested, are included in other expense (income), net, in the accompanying Consolidated Statements of Operations.

Total (gain) loss on foreign currency transactions for the three and six months ended June 30, 2014 and 2015 is as follows:

	Three Months Ended June 30,					Six Months Ended June 30,
	2014			2015		2014		2015
Total (gain) loss on foreign currency transactions	$	(4,347	)	$	1,656	$	2,091	$	23,922

d.    Goodwill and Other Intangible Assets

Goodwill and intangible assets with indefinite lives are not amortized but are reviewed annually for impairment or more frequently if impairment indicators arise. Other than goodwill, we currently have no intangible assets that have indefinite lives and which are not amortized. Separable intangible assets that are not deemed to have indefinite lives are amortized over their useful lives. We annually, or more frequently if events or circumstances warrant, assess whether a change in the lives over which our intangible assets are amortized is necessary.

We have selected October 1 as our annual goodwill impairment review date. We performed our most recent annual goodwill impairment review as of October 1, 2014 and concluded there was no impairment of goodwill at such date. As of December 31, 2014 and June 30, 2015, no factors were identified that would alter our October 1, 2014 goodwill assessment. In making this assessment, we relied on a number of factors including operating results, business plans, anticipated future cash flows, transactions and marketplace data. There are inherent uncertainties related to these factors and our judgment in applying them to the analysis of goodwill impairment. 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 at which level we performed our goodwill impairment analysis as of October 1, 2014 were as follows: (1) North American Records and Information Management; (2) technology escrow services that protect and manage source code (“Intellectual Property Management”); (3) the storage, assembly and detailed reporting of customer marketing literature and delivery to sales offices, trade shows and prospective customers’ sites based on current and prospective customer orders (“Fulfillment Services”); (4) North American Data Management; (5) Emerging Businesses (which primarily relates to our data center business in the United States and which is a component of our Corporate and Other Business segment); (6) the United Kingdom, Ireland, Norway, Austria, Belgium, France, Germany, Netherlands, Spain and Switzerland (“New Western Europe”); (7) the remaining countries in Europe in which we operate, excluding Russia, Ukraine and Denmark (“Emerging Markets - Eastern Europe” (formerly referred to as the "New Emerging Markets" reporting unit)); (8) Latin America; (9) Australia and Singapore; (10) China and Hong Kong (“Greater China”); (11) India; and (12) Russia, Ukraine and Denmark.

The carrying value of goodwill, net for each of our reporting units as of December 31, 2014 was as follows:

	Carrying Value as of December 31, 2014
North American Records and Information Management(1)	$	1,397,484
Intellectual Property Management(1)	38,491
Fulfillment Services(1)	3,247
North American Data Management(2)	375,957

_______________________________________________________________________________

(1) This reporting unit is included in the North American Records and Information Management Business segment.

(2) This reporting unit is included in the North American Data Management Business segment.

(3) This reporting unit is included in the Corporate and Other Business segment.

(4) This reporting unit is included in the Western European Business segment.

(5) This reporting unit is included in the Other International Business segment.

Beginning January 1, 2015, as a result of the changes in our reportable operating segments associated with our reorganization (see Note 7 for a description of our reportable operating segments), we reassessed the composition of our reporting units. Our North American Records and Information Management Business segment now consists of two reporting units: (1) North American Records and Information Management (which includes Intellectual Property Management and Fulfillment Services) and (2) North American Secure Shredding. Our Western European Business segment now consists of two reporting units: (1) the United Kingdom, Ireland and Norway (“UKI”) and (2) Austria, Belgium, France, Germany, Netherlands, Spain and Switzerland (“Continental Western Europe”). We have reassigned goodwill associated with the reporting units impacted by the reorganization among the new reporting units on a relative fair value basis. The fair value of each of our new reporting units was determined based on the application of a combined weighted average approach of preliminary fair value multiples of revenue and earnings and discounted cash flow techniques. These fair values represent our best estimate and preliminary assessment of goodwill allocations to each of the new reporting units on a relative fair value basis.

The carrying value of goodwill, net for each of our reporting units as of June 30, 2015 is as follows:

	Carrying Value as of June 30, 2015
North American Records and Information Management(1)(2)	$	1,389,683
North American Secure Shredding(1)(2)	40,884
North American Data Management(3)	373,698
Emerging Businesses(4)	3,036
UKI(1)(5)	272,226
Continental Western Europe(1)(5)	75,015
Emerging Markets - Eastern Europe(6)	81,772
Latin America(6)	95,445
Australia and Singapore(6)	52,836
Greater China(6)	3,525
India(6)	—
Russia, Ukraine and Denmark(6)	577
Total	$	2,388,697

_______________________________________________________________________________

(1) We will finalize our preliminary estimates of fair value for these new reporting units once we finalize multi-year cash flow forecasts of such reporting units and conclude on the fair value of each new reporting unit based on the combined weighting of both fair value multiples and discounted cash flow techniques. To the extent final fair values of our new reporting units differ from our preliminary estimates, we will reassign goodwill amongst the new reporting units in a future period in which the final information is available to complete the fair values and the corresponding allocation of goodwill amongst the new reporting units.

(2) This reporting unit is included in the North American Records and Information Management Business segment.

(3) This reporting unit is included in the North American Data Management Business segment.

(4) This reporting unit is included in the Corporate and Other Business segment.

(5) This reporting unit is included in the Western European Business segment.

(6) This reporting unit is included in the Other International Business segment.

As a result of the change in the composition of our reporting units noted above, we concluded that we had an interim triggering event, and, therefore, during the first quarter of 2015, we performed an interim goodwill impairment test, as of January 1, 2015, for the North American Records and Information Management, North American Secure Shredding, UKI and Continental Western Europe reporting units. We concluded that the goodwill for each of our new reporting units was not impaired as of such date. While we continue to refine our preliminary estimates of fair value of certain of our new reporting units for purposes of reallocating goodwill, we do not believe that any such changes to preliminary fair value estimates will result in a change in our conclusion that there is no goodwill impairment as of January 1, 2015.

The changes in the carrying value of goodwill attributable to each reportable operating segment for the six months ended June 30, 2015 are as follows:

	North American Records and Information Management Business			North American Data Management Business			Western European Business			Other International Business			Corporate and Other Business		Total Consolidated
Gross Balance as of December 31, 2014	$	1,645,209		$	429,982		$	412,322		$	254,706		$	—	$	2,742,219

Amortization expense associated with amortizable intangible assets (including deferred financing costs) for the three and six months ended June 30, 2014 and 2015 is as follows:

	Three Months Ended June 30,				Six Months Ended June 30,
	2014		2015		2014		2015

e.    Stock-Based Compensation

We record stock-based compensation expense, utilizing the straight-line method, for the cost of stock options, restricted stock, restricted stock units ("RSUs"), performance units ("PUs") and shares of stock issued under our employee stock purchase plan ("ESPP") (together, "Employee Stock-Based Awards").

Stock-based compensation expense for Employee Stock-Based Awards included in the accompanying Consolidated Statements of Operations for the three and six months ended June 30, 2014 was $7,317 ($5,417 after tax or $0.03 per basic and diluted share) and $14,458 ($10,551 after tax or $0.05 per basic and diluted share), respectively. Stock-based compensation expense for Employee Stock-Based Awards for the three and six months ended June 30, 2015 was $7,921 ($5,467 after tax or $0.03 per basic and diluted share) and $14,777 ($10,413 after tax or $0.05 per basic and diluted share), respectively.

Stock-based compensation expense for Employee Stock-Based Awards included in the accompanying Consolidated Statements of Operations related to continuing operations is as follows:

	Three Months Ended June 30,				Six Months Ended June 30,
	2014		2015		2014		2015
Cost of sales (excluding depreciation and amortization)	$	189	$	46	$	379	$	91
Selling, general and administrative expenses	7,128		7,875		14,079		14,686
Total stock-based compensation	$	7,317	$	7,921	$	14,458	$	14,777

The benefits associated with the tax deductions in excess of recognized compensation cost are required to be reported as financing activities in the accompanying Consolidated Statements of Cash Flows. This requirement reduces reported operating cash flows and increases reported financing cash flows. As a result, net financing cash flows from continuing operations included $(66) and $260 for the six months ended June 30, 2014 and 2015, respectively, from the (deficiency) benefit of tax deductions compared to recognized compensation cost. The tax benefit of any resulting excess tax deduction increases the Additional Paid-in Capital ("APIC") pool. Any resulting tax deficiency is deducted from the APIC pool.

Stock Options

Under our various stock option plans, options are generally granted with exercise prices equal to the market price of the stock on the date of grant; however, in certain instances, options are granted at prices greater than the market price of the stock on the date of grant. Certain of the options we issue become exercisable ratably over a period of ten years from the date of grant and have a contractual life of 12 years from the date of grant, unless the holder's employment is terminated sooner. As of June 30, 2015, ten-year vesting options represented 7.4% of total outstanding options. Certain of the options we issue become exercisable ratably over a period of five years from the date of grant and have a contractual life of ten years from the date of grant, unless the holder's employment is terminated sooner. As of June 30, 2015, five-year vesting options represented 46.1% of total outstanding options. The remainder of options we issue become exercisable ratably over a period of three years from the date of grant and have a contractual life of ten years from the date of grant, unless the holder's employment is terminated sooner. As of June 30, 2015, three-year vesting options represented 46.5% of total outstanding options. Our non-employee directors are considered employees for purposes of our stock option plans and stock option reporting. Options granted to our non-employee directors become exercisable immediately upon grant.

The weighted average fair value of options granted for the six months ended June 30, 2014 and 2015 was $5.60 and $4.99 per share, respectively. These values were estimated on the date of grant using the Black-Scholes option pricing model. The weighted average assumptions used for grants in the respective period are as follows:

	Six Months Ended June 30,
Weighted Average Assumptions	2014		2015
Expected volatility	33.9	%	28.6	%
Risk-free interest rate	2.06	%	1.70	%
Expected dividend yield	4	%	5	%
Expected life	6.8 years		5.5 years

Expected volatility is calculated utilizing daily historical volatility over a period that equates to the expected life of the option. The risk-free interest rate was based on the United States Treasury interest rates whose term is consistent with the expected life of the stock options. Expected dividend yield is considered in the option pricing model and represents our current annualized expected per share dividends over the current trade price of our common stock. The expected life (estimated period of time outstanding) of the stock options granted is estimated using the historical exercise behavior of employees.

A summary of option activity for the six months ended June 30, 2015 is as follows:

	Options		Weighted Average Exercise Price		Weighted Average Remaining Contractual Term (Years)	Average Intrinsic Value
Outstanding at December 31, 2014	3,678,246		$	23.37
Granted	696,722		43.64
Exercised	(350,910	)	21.03

Options expected to vest	1,178,890		$	36.57	8.85	$	1,743

The aggregate intrinsic value of stock options exercised for the three and six months ended June 30, 2014 and 2015 is as follows:

	Three Months Ended June 30,				Six Months Ended June 30,
	2014		2015		2014		2015
Aggregate intrinsic value of stock options exercised	$	7,556	$	1,716	$	8,533	$	5,883

Restricted Stock and Restricted Stock Units

Under our various equity compensation plans, we may also grant restricted stock or RSUs. Our restricted stock and RSUs generally have a vesting period of between three and five years from the date of grant. However, beginning in 2015, RSUs granted to our non-employee directors now vest immediately upon grant. All RSUs accrue dividend equivalents associated with the underlying stock as we declare dividends. Dividends will generally be paid to holders of RSUs in cash upon the vesting date of the associated RSU and will be forfeited if the RSU does not vest. The fair value of restricted stock and RSUs is the excess of the market price of our common stock at the date of grant over the purchase price (which is typically zero).

Cash dividends accrued and paid on RSUs for the three and six months ended June 30, 2014 and 2015 are as follows:

	Three Months Ended June 30,				Six Months Ended June 30,
	2014		2015		2014		2015
Cash dividends on RSUs accrued	$	416	$	631	$	850	$	1,301
Cash dividends on RSUs paid	223		571		1,054		2,300

The fair value of restricted stock and RSUs vested during the three and six months ended June 30, 2014 and 2015 are as follows:

	Three Months Ended June 30,				Six Months Ended June 30,
	2014		2015		2014		2015
Fair value of restricted stock vested	$	1	$	—	$	1	$	—
Fair value of RSUs vested	3,704		3,600		17,548		19,184

A summary of restricted stock and RSU activity for the six months ended June 30, 2015 is as follows:

	Restricted Stock and RSUs		Weighted- Average Grant-Date Fair Value
Non-vested at December 31, 2014	1,405,569		$	28.78
Granted	524,896		38.59
Vested	(536,988	)	30.94
Forfeited	(50,678	)	32.14
Non-vested at June 30, 2015	1,342,799		$	33.68

Performance Units

Under our various equity compensation plans, we may also make awards of PUs. For the majority of PUs, the number of PUs earned is determined based on our performance against predefined targets of revenue or revenue growth and return on invested capital ("ROIC"). The number of PUs earned may range from 0% to 150% (for PUs granted prior to 2014) and 0% to 200% (for PUs granted in 2014 and thereafter) 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 either the one-year performance period (for PUs granted prior to 2014) or the three-year performance period (for PUs granted in 2014 and thereafter). Certain PUs granted in 2013, 2014 and 2015 will be earned based on a market condition associated with the total return on our common stock in relation to a subset of the S&P 500 rather than the revenue growth and ROIC targets noted above. The number of PUs earned based on this market condition may range from 0% to 200% of the initial award. All of our PUs will be settled in shares of our common stock and are subject to cliff vesting three years from the date of the original PU grant. For those PUs subject to a one-year performance period, employees who subsequently terminate their employment after the end of the one-year performance period and on or after attaining age 55 and completing 10 years of qualifying service (the "Retirement Criteria") shall immediately and completely vest in any PUs earned based on the actual achievement against the predefined targets as discussed above (but delivery of the shares remains deferred). As a result, PUs subject to a one-year performance period are generally expensed over the shorter of (1) the vesting period, (2) achievement of the Retirement Criteria, which may occur as early as January 1 of the year following the year of grant or (3) a maximum of three years. For those PUs subject to a three-year performance period, employees who terminate their employment during the performance period and on or after meeting the Retirement Criteria are eligible for pro rated vesting, subject to the actual achievement against the predefined targets as discussed above, based on the number of full years of service completed following the grant date (but delivery of the shares remains deferred). As a result, PUs subject to a three-year performance period are generally expensed over the three-year performance period. Outstanding PUs accrue dividend equivalents associated with the underlying stock as we declare dividends. Dividends will generally be paid to holders of PUs in cash upon the settlement date of the associated PU and will be forfeited if the PU does not vest.

Cash dividends accrued and paid on PUs for the three and six months ended June 30, 2014 and 2015 are as follows:

	Three Months Ended June 30,				Six Months Ended June 30,
	2014		2015		2014		2015
Cash dividends on PUs accrued	$	142	$	214	$	292	$	425
Cash dividends on PUs paid	91		—		312		1,015

During the six months ended June 30, 2015, we issued 139,446 PUs. The majority of our PUs are earned based on our performance against revenue or revenue growth and ROIC targets during their applicable performance period; therefore, we forecast the likelihood of achieving the predefined revenue, revenue growth and ROIC 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 applicable performance period) or the actual PUs earned (at the one-year anniversary date for PUs granted prior to 2014, and at the three-year anniversary date for PUs granted in 2014 and thereafter) over the vesting period for each of the awards. For PUs earned based on a market condition, we utilized 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, 2015, we expected 25% and 100% achievement of the predefined revenue, revenue growth and ROIC targets associated with the awards of PUs made in 2014 and 2015, respectively.

The fair value of earned PUs that vested during the three and six months ended June 30, 2014 and 2015 is as follows:

	Three Months Ended June 30,				Six Months Ended June 30,
	2014		2015		2014		2015
Fair value of earned PUs that vested	$	2,266	$	44	$	6,296	$	2,107

A summary of PU activity for the six months ended June 30, 2015 is as follows:

	Original PU Awards		PU Adjustment(1)		Total PU Awards		Weighted- Average Grant-Date Fair Value
Non-vested at December 31, 2014	461,666		(82,609	)	379,057		$	30.80
Granted	139,446		—		139,446		40.38

Non-vested at June 30, 2015	502,039		(86,959	)	415,080		$	34.25

_______________________________________________________________________________

(1) Represents an increase or decrease in the number of original PUs awarded based on either (a) the final performance criteria achievement at the end of the defined performance period of such PUs or (b) a change in estimated awards based on the forecasted performance against the predefined targets.

Employee Stock Purchase Plan

We offer an ESPP in which participation is available to substantially all United States and Canadian employees who meet certain service eligibility requirements. The ESPP provides a way for our eligible employees to become stockholders on favorable terms. The ESPP provides for the purchase of our common stock by eligible employees through successive offering periods. We have historically had twosix-month offering periods per year, the first of which generally runs from June 1 through November 30 and the second of which generally runs from December 1 through May 31. During each offering period, participating employees accumulate after-tax payroll contributions, up to a maximum of 15% of their compensation, to pay the purchase price at the end of the offering. Participating employees may withdraw from an offering before the purchase date and obtain a refund of the amounts withheld as payroll deductions. At the end of the offering period, outstanding options under the ESPP are exercised, and each employee's accumulated contributions are used to purchase our common stock. The price for shares purchased under the ESPP is 95% of the fair market price at the end of the offering period, without a look-back feature. As a result, we do not recognize compensation expense for the ESPP shares purchased. For the six months ended June 30, 2014 and 2015, there were 69,567 shares and 59,569 shares, respectively, purchased under the ESPP. As of June 30, 2015, we have 901,069 shares available under the ESPP.

_______________________________________________________________________________

As of June 30, 2015, unrecognized compensation cost related to the unvested portion of our Employee Stock-Based Awards was $46,910 and is expected to be recognized over a weighted-average period of 2.2 years.

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

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

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

The calculation of basic and diluted income (loss) per share for the three and six months ended June 30, 2014 and 2015 is as follows:

	Three Months Ended June 30,					Six Months Ended June 30,
	2014			2015		2014			2015
Income (loss) from continuing operations	$	272,702		$	54,007	$	315,423		$	95,746

g.    Revenues

Our revenues consist of storage rental revenues as well as service revenues and are reflected net of sales and value added taxes. Storage rental revenues, which are considered a key driver of financial performance for the storage and information management services industry, consist primarily of recurring periodic rental charges related to the storage of materials or data (generally on a per unit basis). Service revenues include charges for related service activities, which include: (1) the handling of records, including the addition of new records, temporary removal of records from storage, refiling of removed records and the destruction of records; (2) courier operations, consisting primarily of the pickup and delivery of records upon customer request; (3) secure shredding of sensitive documents and the related sale of recycled paper, the price of which can fluctuate from period to period; (4) other services, including the scanning, imaging and document conversion services of active and inactive records, or Document Management Solutions ("DMS"), which relate to physical and digital records, and project revenues; (5) customer termination and permanent withdrawal fees; (6) data restoration projects; (7) special project work; (8) Fulfillment Services; (9) consulting services; and (10) Intellectual Property Management and other technology services and product sales (including specially designed storage containers and related supplies).

We recognize revenue when the following criteria are met: persuasive evidence of an arrangement exists, services have been rendered, the sales price is fixed or determinable and collectability of the resulting receivable is reasonably assured. 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. Amounts related to future storage rental or prepaid service contracts for customers where storage rental fees or services are billed in advance are accounted for as deferred revenue and recognized ratably over the period the applicable storage rental or service is provided or performed. Revenues from the sales of products, which are included as a component of service revenues, are recognized when products are shipped and title has passed to the customer. Revenues from the sales of products have historically not been significant.

h.    Allowance for Doubtful Accounts and Credit Memo Reserves

We maintain an allowance for doubtful accounts and credit memos for estimated losses resulting from the potential inability of our customers to make required payments and potential disputes regarding billing and service issues. When calculating the allowance, we consider our past loss experience, current and prior trends in our aged receivables and credit memo activity, current economic conditions and specific circumstances of individual receivable balances. If the financial condition of our customers were to significantly change, resulting in a significant improvement or impairment of their ability to make payments, an adjustment of the allowance may be required. We charge-off uncollectible balances as circumstances warrant, generally, no later than one year past due.

i.    Income Taxes

As noted previously, we have been organized and operating as a REIT effective for our taxable year beginning January 1, 2014. As a REIT, we are generally permitted to deduct from our federal taxable income the dividends we pay to our stockholders. The income represented by such dividends is not subject to federal taxation at the entity level but may be taxed at the stockholder level. The income of our domestic taxable REIT subsidiaries (“TRSs”), which hold our domestic operations that may not be REIT‑compliant as currently operated and structured, is subject, as applicable, to federal and state corporate income tax. In addition, we and our subsidiaries continue to be subject to foreign income taxes in jurisdictions in which we have business operations or a taxable presence, regardless of whether assets are held or operations are conducted through subsidiaries disregarded for federal tax purposes or as TRSs. We will also be subject to a separate corporate income tax on any gains recognized during a specified period (generally ten years) following the REIT conversion that are attributable to “built‑in” gains with respect to the assets that we owned on January 1, 2014; this built‑in gains tax has been imposed on our depreciation recapture recognized into income in 2014 and generally will be imposed in subsequent years as a result of accounting method changes commenced in our pre‑REIT period. If we fail to remain qualified for taxation as a REIT, we will be subject to federal income tax at regular corporate tax rates. Even if we remain qualified for taxation as a REIT, we may be subject to some federal, state, local and foreign taxes on our income and property in addition to taxes owed with respect to our TRS operations. In particular, while state income tax regimes often parallel the federal income tax regime for REITs, many states do not completely follow federal rules and some do not follow them at all.

We provide for income taxes during interim periods based on our estimate of the effective tax rate for the year. Discrete items and changes in our estimate of the annual effective tax rate are recorded in the period they occur. Our effective tax rate is subject to variability in the future due to, among other items: (1) changes in the mix of income between our qualified REIT subsidiaries and our TRSs, as well as between 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. We are subject to income taxes in the United States and numerous foreign jurisdictions. We are subject to examination by various tax authorities in jurisdictions in which we have business operations or a taxable presence. We regularly assess the likelihood of additional assessments by tax authorities and provide for these matters as appropriate. Although we believe our tax estimates are appropriate, the final determination of tax audits and any related litigation could result in changes in our estimates.

Accounting for income taxes requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the tax and financial reporting bases of assets and liabilities and for loss and credit carryforwards. Valuation allowances are provided when recovery of deferred tax assets does not meet the more likely than not standard as defined in GAAP.

We have elected to recognize interest and penalties associated with uncertain tax positions as a component of the provision (benefit) for income taxes in the accompanying Consolidated Statements of Operations. We recorded a decrease of $631 and an increase of $335 for gross interest and penalties for the three and six months ended June 30, 2014, respectively. We recorded an increase of $637 and $1,579 for gross interest and penalties for the three and six months ended June 30, 2015, respectively. We had $5,884 and $6,756 accrued for the payment of interest and penalties as of December 31, 2014 and June 30, 2015, respectively.

As a result of our REIT conversion, we recorded a net tax benefit of $230,051 and $212,151 during the three and six months ended June 30, 2014, respectively, for the revaluation of certain deferred tax assets and liabilities and other income taxes associated with the REIT conversion. The other primary reconciling items between the federal statutory rate of 35% and our overall effective tax rate in the three and six months ended June 30, 2014 were a $36,084 increase in our tax provision recognized in the second quarter of 2014 associated with incremental federal and state income taxes and foreign withholding taxes on earnings of our foreign subsidiaries no longer considered permanently invested and other net tax benefit related to the REIT conversion of $18,763 and $33,835, respectively, primarily related to the dividends paid deduction.

Our effective tax rates for the three and six months ended June 30, 2015 were 12.1% and 19.6%, respectively. The primary reconciling items between the federal statutory rate of 35% and our overall effective tax rate in the three and six months ended June 30, 2015 were the benefit derived from the dividends paid deduction, differences in the rates of tax at which our foreign earnings are subject, including foreign exchange gains and losses in different jurisdictions with different tax rates and state income taxes (net of federal tax benefit).

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

j.    Concentrations of Credit Risk

Financial instruments that potentially subject us to credit risk consist principally of cash and cash equivalents (including money market funds and time deposits), restricted cash (primarily United States Treasuries) and accounts receivable. The only significant concentrations of liquid investments as of December 31, 2014 relate to cash and cash equivalents and restricted cash held on deposit and as of June 30, 2015 relate to cash and cash equivalents. At December 31, 2014, we had money market funds with two "Triple A" rated money market funds and time deposits with three global banks. At June 30, 2015, we had time deposits with three global banks and no money market funds. We consider the "Triple A" rated money market funds and the global banks to be large, highly-rated investment-grade institutions. As per our risk management investment policy, we limit exposure to concentration of credit risk by limiting the amount invested in any one mutual fund to a maximum of $50,000 or in any one financial institution to a maximum of $75,000. As of December 31, 2014 and June 30, 2015, our cash and cash equivalents and restricted cash balance was $159,793 and $117,098, respectively, including money market funds and time deposits amounting to $53,032 and $20,802, respectively. The money market funds were invested substantially in United States Treasuries.

k.    Fair Value Measurements

Entities are permitted under GAAP to elect to measure many financial instruments and certain other items at either fair value or cost. We did not elect the fair value measurement option.

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

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

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

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

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

The assets and liabilities carried at fair value measured on a recurring basis as of December 31, 2014 and June 30, 2015, respectively, are as follows:

			Fair Value Measurements at December 31, 2014 Using
Description	Total Carrying Value at December 31, 2014		Quoted prices in active markets (Level 1)			Significant other observable inputs (Level 2)			Significant unobservable inputs (Level 3)
Money Market Funds(1)	$	36,828	$	—		$	36,828		$	—
Time Deposits(1)	16,204		—			16,204			—
Trading Securities	13,172		12,428		(2)	744		(1)	—
Derivative Liabilities(3)	2,411		—			2,411			—

			Fair Value Measurements at June 30, 2015 Using
Description	Total Carrying Value at June 30, 2015		Quoted prices in active markets (Level 1)			Significant other observable inputs (Level 2)			Significant unobservable inputs (Level 3)
Time Deposits(1)	$	20,802	$	—		$	20,802		$	—
Trading Securities	10,960		10,086		(2)	874		(1)	—
Derivative Assets(3)	6,362		—			6,362			—

_______________________________________________________________________________

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

(2) Securities are measured at fair value using quoted market prices.

(3) Our 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 intercompany exposures, as more fully disclosed at 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.

Disclosures are required in the financial statements for items measured at fair value on a non-recurring basis. We did not have any material items that are measured at fair value on a non-recurring basis for the three and six months ended June 30, 2014 and 2015.

l.    Use of Estimates

The preparation of financial statements in conformity with GAAP requires us to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities at the date of the financial statements and for the period then ended. On an ongoing basis, we evaluate the estimates used. We base our estimates on historical experience, actuarial estimates, current conditions and various other assumptions that we believe to be reasonable under the circumstances. These estimates form the basis for making judgments about the carrying values of assets and liabilities and are not readily apparent from other sources. Actual results may differ from these estimates.

o.    Property, Plant and Equipment and Long-Lived Assets

We develop various software applications for internal use. Computer software costs associated with internal use software are expensed as incurred until certain capitalization criteria are met. Payroll and related costs for employees directly associated with, and devoting time to, the development of internal use computer software projects (to the extent time is spent directly on the project) are capitalized. During the three and six months ended June 30, 2014, we capitalized $4,861 and $9,758 of costs, respectively, associated with the development of internal use computer software projects. During the three and six months ended June 30, 2015, we capitalized $6,395 and $12,435 of costs, respectively, associated with the development of internal use computer software projects. Capitalization begins when the design stage of the application has been completed and it is probable that the project will be completed and used to perform the function intended. Capitalization ends when the asset is ready for its intended use. Depreciation begins when the software is placed in service. Computer software costs that are capitalized are periodically evaluated for impairment.

We review long-lived assets and all amortizable intangible assets for impairment whenever events or changes in circumstances indicate the carrying amount of such assets may not be recoverable. Recoverability of these assets is determined by comparing the forecasted undiscounted net cash flows of the operation to which the assets relate to their carrying amount. The operations are generally distinguished by the business segment and geographic region in which they operate. If the operation is determined to be unable to recover the carrying amount of its assets, the long-lived assets are written down, on a pro rata basis, to fair value. Fair value is determined based on discounted cash flows or appraised values, depending upon the nature of the assets.

As a result of our conversion to a REIT and in accordance with SEC rules applicable to REITs, we no longer report (gain) loss on the sale of real estate as a component of operating income, but we report it as a component of income (loss) from continuing operations. We report the (gain) loss on sale of property, plant and equipment (excluding real estate), along with any impairment, write-downs or involuntary conversions related to real estate, as a component of operating income. Previously reported amounts have been reclassified to conform to this presentation.

Consolidated (gain) loss on disposal/write-down of property, plant and equipment (excluding real estate), net was $(107) and $1,045 for the three and six months ended June 30, 2014, respectively. Losses in the six months ended June 30, 2014 were primarily associated with the write-off of certain software associated with our North American Records and Information Management Business segment. Consolidated loss on disposal/write-down of property, plant and equipment (excluding real estate), net was $515 and $848 for the three and six months ended June 30, 2015, respectively, and consisted primarily of the write-off of certain property associated with our North American Records and Information Management Business segment.

Consolidated gain on sale of real estate was $7,468, net of tax of $1,991, for the six months ended June 30, 2014 associated with the sale of two buildings in the United Kingdom.

p.    New Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU 2014-09"). ASU 2014-09 provides additional 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, (3) licenses, (4) time value of money and (5) contract costs. Further disclosures will be required to provide a better understanding of revenue that has been recognized and revenue that is expected to be recognized in the future from existing contracts. In July 2015, the FASB deferred the effective date of ASU 2014-09 for one year, making it effective for our year beginning January 1, 2018, with early adoption permitted as of January 1, 2017. We are currently evaluating the impact ASU 2014-09 will have on our consolidated financial statements.

In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements Going Concern (Subtopic 205-40) (“ASU 2014-15”). ASU 2014-15 requires management to assess an entity’s ability to continue as a going concern by incorporating and expanding upon certain principles of current United States auditing standards. Specifically, the amendments (1) provide a definition of the term “substantial doubt”, (2) require an evaluation every reporting period, including interim periods, (3) provide principles for considering the mitigating effect of management’s plans, (4) require certain disclosures when substantial doubt is alleviated as a result of consideration of management’s plans, (5) require an express statement and other disclosures when substantial doubt is still present, and (6) require an assessment for a period of one year after the date that the financial statements are issued (or available to be issued). ASU 2014‑15 is effective for us on January 1, 2017, with early adoption permitted. We do not believe that this pronouncement will have an impact on our consolidated financial statements.

In February 2015, the FASB issued ASU No. 2015‑02, Consolidation (Topic 810): Amendments to the Consolidation Analysis (“ASU 2015‑02”). ASU 2015‑02 affects reporting entities that are required to evaluate whether they should consolidate certain legal entities. ASU 2015‑02 is effective for us on January 1, 2016, with early adoption permitted. We do not believe that this pronouncement will have an impact on our consolidated financial statements.

In April 2015, the FASB issued ASU No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs (“ASU 2015-03”).  The amendments in ASU 2015-03 require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts.  The recognition and measurement guidance for debt issuance costs are not affected by the amendments in ASU 2015-03.  ASU 2015‑03 is effective for us on January 1, 2016, with early adoption permitted.  We do not believe that this pronouncement will have a material impact on our consolidated financial statements.

Derivative Instruments and Hedging Activities Disclosure [Text Block]

Every derivative instrument is required to be recorded in the balance sheet as either an asset or a liability measured at its fair value. Periodically, we acquire derivative instruments that are intended to hedge either cash flows or values that are subject to foreign exchange or other market price risk and not for trading purposes. We have formally documented our hedging relationships, including identification of the hedging instruments and the hedged items, as well as our risk management objectives and strategies for undertaking each hedge transaction. Given the recurring nature of our revenues and the long-term nature of our asset base, we have the ability and the preference to use long-term, fixed interest rate debt to finance our business, thereby preserving our long-term returns on invested capital. We target approximately 75% of our debt portfolio to be fixed with respect to interest rates. Occasionally, we may use interest rate swaps as a tool to maintain our targeted level of fixed rate debt. In addition, we may use borrowings in foreign currencies, either obtained in the United States or by our foreign subsidiaries, to hedge foreign currency risk associated with our international investments. Sometimes we enter into currency swaps to temporarily hedge an overseas investment, such as a major acquisition, while we arrange permanent financing or to hedge our exposure due to foreign currency exchange movements related to our intercompany accounts with and between our foreign subsidiaries. As of December 31, 2014 and June 30, 2015, none of our derivative instruments contained credit-risk related contingent features.

We have entered into a number of separate forward contracts to hedge our exposures in Euros, British pounds sterling and Australian dollars. As of June 30, 2015, we had outstanding forward contracts to purchase 212,500 Euros and sell $231,385 United States dollars to hedge our intercompany exposures with our European operations. At the maturity of the forward contracts, we may enter into new forward contracts to hedge movements in the underlying currencies. At the time of settlement, we either pay or receive the net settlement amount from the forward contract and recognize this amount in other expense (income), net in the Consolidated Statements of Operations as a realized foreign exchange gain or loss. At the end of each month, we mark the outstanding forward contracts to market and record an unrealized foreign exchange gain or loss for the mark-to-market valuation. We have not designated forward contracts as hedges.

Net cash payments (receipts) included in cash from operating activities related to settlements associated with foreign currency forward contracts for the three and six months ended June 30, 2014 and 2015, respectively, are as follows:

Stockholders' Equity Matters

Equity [Abstract]

Stockholders' Equity Matters

Stockholders' Equity Matters

In February 2010, our board of directors adopted a dividend policy under which we have paid, and in the future intend to pay, quarterly cash dividends on our common stock. Declaration and payment of future quarterly dividends is at the discretion of our board of directors.

On September 15, 2014, we announced the declaration by our board of directors of a special distribution of $700,000 (the "Special Distribution"), payable to stockholders of record as of September 30, 2014 (the "Record Date"). The Special Distribution represented the remaining amount of our undistributed earnings and profits attributable to all taxable periods ending on or prior to December 31, 2013, which in accordance with tax rules applicable to REIT conversions, we were required to pay to our stockholders on or before December 31, 2014 in connection with our conversion to a REIT. The Special Distribution also included certain items of taxable income that we recognized in 2014, such as depreciation recapture in respect of accounting method changes commenced in our pre-REIT period as well as foreign earnings and profits recognized as dividend income. The Special Distribution followed an initial special distribution of $700,000 paid to stockholders in November 2012.

The Special Distribution was paid on November 4, 2014 (the "Payment Date") to stockholders of record as of the Record Date in a combination of common stock and cash. Stockholders had the right to elect to be paid their pro rata portion of the Special Distribution in all common stock or all cash, with the total cash payment to stockholders limited to no more than $140,000, or 20% of the total Special Distribution, not including cash paid in lieu of fractional shares. Based on stockholder elections, we paid $140,000 of the Special Distribution in cash, not including cash paid in lieu of fractional shares, with the balance paid in the form of common stock. Our shares of common stock were valued for purposes of the Special Distribution based upon the average closing price on the three trading days following October 24, 2014, or $35.55 per share, and as such, we issued approximately 15,750,000 shares of common stock in the Special Distribution. These shares impact weighted average shares outstanding from the date of issuance, and thus will impact our earnings per share data prospectively from the Payment Date.

In November 2014, our board of directors declared a distribution of $0.255 per share (the “Catch‑Up Distribution”) payable on December 15, 2014 to stockholders of record on November 28, 2014. Our board of directors declared the Catch‑Up Distribution because our cash distributions paid from January 2014 through July 2014 were declared and paid before our board of directors had determined that we would elect REIT status effective January 1, 2014 and were lower than they otherwise would have been if the final determination to elect REIT status effective January 1, 2014 had been prior to such distributions.

In fiscal year 2014 and in the first six months of 2015, our board of directors declared the following dividends:

Declaration Date	Dividend Per Share		Record Date	Total Amount		Payment Date
March 14, 2014	$	0.2700	March 25, 2014	$	51,812	April 15, 2014

(1) The capital stock or other equity interests of most of our United States subsidiaries, and up to 66% of the capital stock or other equity interests of our first-tier foreign subsidiaries, are pledged to secure these debt instruments, together with all intercompany obligations (including promissory notes) of subsidiaries owed to us or to one of our United States subsidiary guarantors. In addition, Iron Mountain Canada Operations ULC ("Canada Company") has pledged 66% of the capital stock of its subsidiaries, and all intercompany obligations (including promissory notes) owed to or held by it, to secure the Canadian dollar subfacility under the IMI Revolving Credit Facility (defined below). The fair value (Level 3 of fair value hierarchy described at Note 2.k.) of these debt instruments approximates the carrying value (as borrowings under these debt instruments are based on current variable market interest rates (plus a margin that is subject to change based on our consolidated leverage ratio)), as of both December 31, 2014 and June 30, 2015.

(2) The fair values (Level 1 of fair value hierarchy described at Note 2.k.) of these debt instruments are based on quoted market prices for these notes on December 31, 2014 and June 30, 2015, respectively.

(3) Collectively, the "Parent Notes." IMI is the direct obligor on the Parent Notes, which are fully and unconditionally guaranteed, on a senior or senior subordinated basis, as the case may be, by most of its direct and indirect 100% owned United States subsidiaries (the "Guarantors"). These guarantees are joint and several obligations of the Guarantors. Canada Company, Iron Mountain Europe PLC ("IME"), the Special Purpose Subsidiaries (as defined below) and the remainder of our subsidiaries do not guarantee the Parent Notes.

(4) Canada Company is the direct obligor on the CAD Notes, which are fully and unconditionally guaranteed, on a senior basis, by IMI and the Guarantors. These guarantees are joint and several obligations of IMI and the Guarantors. See Note 6 to Notes to Consolidated Financial Statements.

(5) IME is the direct obligor on the GBP Notes, which are fully and unconditionally guaranteed, on a senior basis, by IMI and the Guarantors. These guarantees are joint and several obligations of IMI and the Guarantors. See Note 6 to Notes to Consolidated Financial Statements.

(6) The Special Purpose Subsidiaries are the obligors under this program.

(7) We believe the fair value (Level 3 of fair value hierarchy described at Note 2.k.) of this debt approximates its carrying

value.

The revolving credit facilities (the "IMI Revolving Credit Facility") under our credit agreement, as amended (the "Credit Agreement"), allowed IMI and certain of its United States and foreign subsidiaries to borrow in United States dollars and (subject to sublimits) a variety of other currencies (including Canadian dollars, British pounds sterling, Euros, Brazilian reais, and Australian dollars, among other currencies) in an aggregate outstanding amount not to exceed $1,500,000. Additionally, the Credit Agreement included an option to allow us to request additional commitments of up to $500,000, in the form of term loans or through increased commitments under the IMI Revolving Credit Facility. On September 24, 2014, we exercised this option and borrowed an additional $250,000 in the form of a term loan under the Credit Agreement (the "IMI Term Loan"). Commencing on December 31, 2014, the IMI Term Loan began to amortize in quarterly installments in an amount equal to $625 per quarter, with the remaining balance due on June 27, 2016. The IMI Term Loan could be prepaid without penalty or premium, in whole or in part, at any time. The Credit Agreement included an option to allow us to request additional commitments of up to $250,000, in the form of term loans or through increased commitments under the IMI Revolving Credit Facility. On July 2, 2015, we entered into a new credit agreement, as described at Note 10, to refinance the Credit Agreement.

IMI and the Guarantors guaranteed all obligations under the Credit Agreement, and have pledged the capital stock or other equity interests of most of their United States subsidiaries, up to 66% of the capital stock or other equity interests of their first-tier foreign subsidiaries, and all intercompany obligations (including promissory notes) owed to or held by them to secure the Credit Agreement. In addition, Canada Company has pledged 66% of the capital stock of its subsidiaries, and all intercompany obligations (including promissory notes) owed to or held by it to secure the Canadian dollar subfacility under the IMI Revolving Credit Facility. The interest rate on borrowings under the Credit Agreement varied depending on our choice of interest rate and currency options, plus an applicable margin, which varied based on our consolidated leverage ratio. Additionally, the Credit Agreement required the payment of a commitment fee on the unused portion of the IMI Revolving Credit Facility, which fee ranged from between 0.3% to 0.5% based on certain financial ratios and fees associated with outstanding letters of credit. As of June 30, 2015, we had $834,753 and $248,125 of outstanding borrowings under the IMI Revolving Credit Facility and the IMI Term Loan, respectively. Of the $834,753 of outstanding borrowings under the IMI Revolving Credit Facility, $631,900 was denominated in United States dollars, 81,200 was denominated in Canadian dollars, 73,750 was denominated in Euros and 71,600 was denominated in Australian dollars. In addition, we also had various outstanding letters of credit totaling $33,835. The remaining amount available for borrowing under the IMI Revolving Credit Facility as of June 30, 2015, based on IMI's leverage ratio, the last 12 months' earnings before interest, taxes, depreciation and amortization and rent expense ("EBITDAR"), other adjustments as defined in the Credit Agreement and current external debt, was $631,412 (which amount represents the maximum availability as of such date). The average interest rate in effect under the Credit Agreement was 2.8% as of June 30, 2015. The average interest rate in effect under the IMI Revolving Credit Facility was 3.0% and ranged from 2.3% to 4.5% as of June 30, 2015 and the interest rate in effect under the IMI Term Loan as of June 30, 2015 was 2.4%.

In March 2015, we entered into a $250,000 accounts receivable securitization program (the "Accounts Receivable Securitization Program") involving several of our wholly owned subsidiaries and certain financial institutions. Under the Accounts Receivable Securitization Program, certain of our subsidiaries sell substantially all of their United States accounts receivable balances to our wholly owned special purpose entities, Iron Mountain Receivables QRS, LLC and Iron Mountain Receivables TRS, LLC (the "Special Purpose Subsidiaries"). The Special Purpose Subsidiaries use the accounts receivable balances to collateralize loans obtained from certain financial institutions. Iron Mountain Information Management, LLC retains the responsibility of servicing the accounts receivable balances pledged as collateral in this transaction and IMI provides a performance guaranty. The Accounts Receivable Securitization Program terminates on March 6, 2018, at which point all obligations become due. The maximum availability allowed is limited by eligible accounts receivable, as defined under the terms of the Accounts Receivable Securitization Program.  As of June 30, 2015, the maximum availability allowed and amount outstanding under the Accounts Receivable Securitization Program was $217,500. The interest rate in effect under the Accounts Receivable Securitization Program was 1.1% as of June 30, 2015. Commitment fees at a rate of 40 basis points are charged on amounts made available but not borrowed under the Accounts Receivable Securitization Program.

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, 2014 and June 30, 2015 are as follows:

	December 31, 2014	June 30, 2015	Maximum//Minimum Allowable
Net total lease adjusted leverage ratio	5.4	5.7	Maximum allowable of 6.5
Net secured debt lease adjusted leverage ratio	2.6	2.8	Maximum allowable of 4.0
Bond leverage ratio (not lease adjusted)	5.7	5.8	Maximum allowable of 6.5
Fixed charge coverage ratio	2.5	2.3	Minimum allowable of 1.5

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

Commitment fees and letters of credit fees, which are based on the unused balances under the IMI Revolving Credit Facility and the Accounts Receivable Securitization Program for the three and six months ended June 30, 2014 and 2015 is as follows:

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

Derivative Instruments and Hedging Activities

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments and Hedging Activities Disclosure [Text Block]

Every derivative instrument is required to be recorded in the balance sheet as either an asset or a liability measured at its fair value. Periodically, we acquire derivative instruments that are intended to hedge either cash flows or values that are subject to foreign exchange or other market price risk and not for trading purposes. We have formally documented our hedging relationships, including identification of the hedging instruments and the hedged items, as well as our risk management objectives and strategies for undertaking each hedge transaction. Given the recurring nature of our revenues and the long-term nature of our asset base, we have the ability and the preference to use long-term, fixed interest rate debt to finance our business, thereby preserving our long-term returns on invested capital. We target approximately 75% of our debt portfolio to be fixed with respect to interest rates. Occasionally, we may use interest rate swaps as a tool to maintain our targeted level of fixed rate debt. In addition, we may use borrowings in foreign currencies, either obtained in the United States or by our foreign subsidiaries, to hedge foreign currency risk associated with our international investments. Sometimes we enter into currency swaps to temporarily hedge an overseas investment, such as a major acquisition, while we arrange permanent financing or to hedge our exposure due to foreign currency exchange movements related to our intercompany accounts with and between our foreign subsidiaries. As of December 31, 2014 and June 30, 2015, none of our derivative instruments contained credit-risk related contingent features.

We have entered into a number of separate forward contracts to hedge our exposures in Euros, British pounds sterling and Australian dollars. As of June 30, 2015, we had outstanding forward contracts to purchase 212,500 Euros and sell $231,385 United States dollars to hedge our intercompany exposures with our European operations. At the maturity of the forward contracts, we may enter into new forward contracts to hedge movements in the underlying currencies. At the time of settlement, we either pay or receive the net settlement amount from the forward contract and recognize this amount in other expense (income), net in the Consolidated Statements of Operations as a realized foreign exchange gain or loss. At the end of each month, we mark the outstanding forward contracts to market and record an unrealized foreign exchange gain or loss for the mark-to-market valuation. We have not designated forward contracts as hedges.

Net cash payments (receipts) included in cash from operating activities related to settlements associated with foreign currency forward contracts for the three and six months ended June 30, 2014 and 2015, respectively, are as follows:

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

Net cash payments (receipts)	$	7,330	$	12,368	$	14,529	$	29,188

Our policy is to record the fair value of each derivative instrument on a gross basis. The fair value of our derivative instruments as of December 31, 2014 and June 30, 2015 and their gains and losses for the three and six months ended June 30, 2014 and 2015 are as follows:

We have designated a portion of the 6³/₄% Notes as a hedge of net investment of certain of our Euro denominated subsidiaries. For the six months ended June 30, 2014 and 2015, we designated on average 58,735 and 35,786 Euros, respectively, of the 6³/₄% Notes as a hedge of net investment of certain of our Euro denominated subsidiaries. As a result, we recorded the following foreign exchange gains (losses), net of tax, 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:

Acquisitions

6 Months Ended

Jun. 30, 2015

Business Combinations [Abstract]

Acquisitions

We account for acquisitions using the acquisition method of accounting, and, accordingly, the assets and liabilities acquired were 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. Cash consideration for our various acquisitions was primarily provided through borrowings under our credit facilities and cash equivalents on‑hand. The unaudited pro forma results of operations (including revenue and earnings) for the current and prior periods are not presented due to the insignificant impact of the 2014 and 2015 acquisitions on our consolidated results of operations.

In the first six months of 2015, in order to enhance our existing operations in the United States, United Kingdom, Canada, Australia and Chile, we completed six acquisitions for total consideration of approximately $18,400. These acquisitions included four storage and records management companies, one storage and data management company and one personal storage company. The individual purchase prices of these acquisitions ranged from approximately $2,300 to approximately $5,500.

A summary of the cumulative consideration paid and the preliminary allocation of the purchase price paid for these acquisitions is as follows:

Cash Paid (gross of cash acquired)	$	18,433		(1)
Total Consideration	18,433
Fair Value of Identifiable Assets Acquired:
Cash, Accounts Receivable, Prepaid Expenses, Deferred Income Taxes and Other	1,162
Property, Plant and Equipment(2)	4,050
Customer Relationship Assets(3)	9,922
Other Assets	361
Liabilities Assumed and Deferred Income Taxes(4)	(5,413		)
Total Fair Value of Identifiable Net Assets Acquired	10,082
Goodwill Initially Recorded	$	8,351

_______________________________________________________________________________

(1) Included in cash paid for acquisitions in the Consolidated Statements of Cash Flows for the six months ended June 30, 2015 is net cash acquired of $(325) and contingent and other payments of $3,606 related to acquisitions made in previous years.

(2) Consists primarily of buildings, racking structures, leasehold improvements and computer hardware and software.

(3) The weighted average lives of customer relationship intangible assets associated with acquisitions in 2015 was 18 years.

(4) Consists primarily of accrued expenses and deferred income taxes.

On June 8, 2015, we entered into a binding Scheme Implementation Deed (the “Recall Agreement”) with Recall Holdings Limited (“Recall”) to acquire Recall (the “Recall Transaction”) by way of a recommended court approved Scheme of Arrangement (the “Scheme”). Under the terms of the Recall Agreement, Recall shareholders are entitled to receive the Australian dollar equivalent of US$0.50 in cash for each outstanding share of Recall common stock (the “Cash Supplement”) as well as either (1) 0.1722 shares of our common stock for each Recall share or (2) 8.50 Australian dollars less the Australian dollar equivalent of US$0.50 in cash for each Recall share (the “Cash Election”). The Cash Election is subject to a proration mechanism that will cap the total amount of cash paid to Recall shareholders electing the Cash Election at 225,000 Australian dollars (the “Cash Election Cap”). Amounts paid to Recall shareholders that represent the Cash Supplement are excluded from the calculation of the Cash Election Cap. Assuming a sufficient number of Recall shareholders elect the Cash Election such that we pay the Cash Election Cap, we expect to issue approximately 51,000,000 shares of our common stock and, based on the exchange rate between the United States dollar and the Australian dollar as of June 30, 2015, pay approximately US$335,000 to Recall shareholders in connection with the Recall Transaction. Completion of the Scheme is subject to customary closing conditions, including among others, (i) approval by Recall shareholders of the Scheme by the requisite majorities under the Australian Corporations Act, (ii) approval by our shareholders of the issuance of shares of our common stock in connection with the Recall Transaction by the requisite majority, (iii) expiration or earlier termination of any applicable waiting period and receipt of regulatory consents, approvals and clearances, in each case, under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and under relevant antitrust/competition and foreign investment legislation in other relevant jurisdictions, (iv) the absence of any final and non-appealable order, decree or law preventing, making illegal or prohibiting the completion of the Recall Transaction, (v) approval from the New York Stock Exchange to the listing of additional shares of our common stock to be issued in the Recall Transaction, (vi) the establishment of a secondary listing on the Australian Securities Exchange (the “ASX”) to allow Recall shareholders to trade our common stock via CHESS Depository Interests on the ASX, (vii) Recall’s delivery of tax opinions in accordance and in compliance with certain tax matter agreements to which Recall is a party and (viii) no events having occurred that would have a material adverse effect on Recall or us. We expect the Recall Transaction to close in the first half of 2016.

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

6 Months Ended

Jun. 30, 2015

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

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, 2014 and June 30, 2015 and for the three and six months ended June 30, 2014 and 2015 and are prepared on the same basis as the consolidated financial statements.

The Parent Notes, CAD Notes and GBP 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 and the Guarantors guarantee the CAD Notes, which were issued by Canada Company, and the GBP Notes, which were issued by IME. Canada Company and IME do not guarantee the Parent Notes. The subsidiaries that do not guarantee the Parent Notes, the CAD Notes and the GBP Notes, including IME and the Special Purpose Subsidiaries but excluding Canada Company, are referred to below as the Non-Guarantors.

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, Canada Company or a Non-Guarantor. If such a change occurs, the amount of investment in subsidiaries in the below consolidated balance sheets and equity in the earnings (losses) of subsidiaries, net of tax in the below consolidated statements of operations with respect to the relevant Parent, Guarantors, Canada Company, Non-Guarantors and Eliminations columns also would change.

In March 2015, we entered into the Accounts Receivable Securitization Program, which is described more fully in Note 5. The Special Purpose Subsidiaries, which were established in conjunction with the Accounts Receivable Securitization Program, are included in the Non-Guarantors column in the below consolidated balance sheet, consolidated statements of operations and consolidated statement of cash flows from that date forward. As a result of the Accounts Receivable Securitization Program, certain of our Guarantors sold substantially all of their United States accounts receivable balances to the Special Purpose Subsidiaries. As of June 30, 2015, this resulted in a decrease in accounts receivable, an increase in intercompany receivable and a decrease in long-term debt related to our Guarantors and a corresponding increase in accounts receivable, an increase in intercompany payable and an increase in long-term debt related to our Non-Guarantors. There was no material impact to the Guarantors and Non-Guarantors columns of the below consolidated statements of operations for the three and six months ended June 30, 2015. Additionally, the Accounts Receivable Securitization Program resulted in increased financing cash flow activity for our Non-Guarantor subsidiaries for the six months ended June 30, 2015, as the proceeds from borrowings under the Accounts Receivable Securitization Program were used to repay intercompany loans with certain of our Guarantor subsidiaries, which resulted in increased cash flows from investing activities for our Guarantor subsidiaries for the six months ended June 30, 2015.

Summary of Significant Accounting Policies (Policies)

6 Months Ended

Jun. 30, 2015

Accounting Policies [Abstract]

Cash and Cash Equivalents

Cash, Cash Equivalents and Restricted Cash

Cash and cash equivalents include cash on hand and cash invested in highly liquid short-term securities, which have remaining maturities at the date of purchase of less than 90 days. Cash and cash equivalents are carried at cost, which approximates fair value.

Foreign Currency Transactions and Translations

Foreign Currency

Local currencies are the functional currencies for our operations outside the United States, with the exception of certain foreign holding companies and our financing centers in Switzerland, whose functional currency is the United States dollar. In those instances where the local currency is the functional currency, assets and liabilities are translated at period-end exchange rates, and revenues and expenses are translated at average exchange rates for the applicable period. Resulting translation adjustments are reflected in the accumulated other comprehensive items, net component of Iron Mountain Incorporated Stockholders' Equity and Noncontrolling Interests in the accompanying Consolidated Balance Sheets. The gain or loss on foreign currency transactions, calculated as the difference between the historical exchange rate and the exchange rate at the applicable measurement date, including those related to (1) our previously outstanding 7¹/₄% GBP Senior Subordinated Notes due 2014 (the "7¹/₄% Notes"), (2) our 6³/₄% Euro Senior Subordinated Notes due 2018 (the "6³/₄% Notes"), (3) borrowings in certain foreign currencies under our revolving credit facility and (4) certain foreign currency denominated intercompany obligations of our foreign subsidiaries to us and between our foreign subsidiaries, which are not considered permanently invested, are included in other expense (income), net, in the accompanying Consolidated Statements of Operations.

Goodwill and Other Intangible Assets

Goodwill and Other Intangible Assets

Goodwill and intangible assets with indefinite lives are not amortized but are reviewed annually for impairment or more frequently if impairment indicators arise. Other than goodwill, we currently have no intangible assets that have indefinite lives and which are not amortized. Separable intangible assets that are not deemed to have indefinite lives are amortized over their useful lives. We annually, or more frequently if events or circumstances warrant, assess whether a change in the lives over which our intangible assets are amortized is necessary.

We have selected October 1 as our annual goodwill impairment review date. We performed our most recent annual goodwill impairment review as of October 1, 2014 and concluded there was no impairment of goodwill at such date. As of December 31, 2014 and June 30, 2015, no factors were identified that would alter our October 1, 2014 goodwill assessment. In making this assessment, we relied on a number of factors including operating results, business plans, anticipated future cash flows, transactions and marketplace data. There are inherent uncertainties related to these factors and our judgment in applying them to the analysis of goodwill impairment. 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 at which level we performed our goodwill impairment analysis as of October 1, 2014 were as follows: (1) North American Records and Information Management; (2) technology escrow services that protect and manage source code (“Intellectual Property Management”); (3) the storage, assembly and detailed reporting of customer marketing literature and delivery to sales offices, trade shows and prospective customers’ sites based on current and prospective customer orders (“Fulfillment Services”); (4) North American Data Management; (5) Emerging Businesses (which primarily relates to our data center business in the United States and which is a component of our Corporate and Other Business segment); (6) the United Kingdom, Ireland, Norway, Austria, Belgium, France, Germany, Netherlands, Spain and Switzerland (“New Western Europe”); (7) the remaining countries in Europe in which we operate, excluding Russia, Ukraine and Denmark (“Emerging Markets - Eastern Europe” (formerly referred to as the "New Emerging Markets" reporting unit)); (8) Latin America; (9) Australia and Singapore; (10) China and Hong Kong (“Greater China”); (11) India; and (12) Russia, Ukraine and Denmark.

Stock-Based Compensation

Stock-Based Compensation

We record stock-based compensation expense, utilizing the straight-line method, for the cost of stock options, restricted stock, restricted stock units ("RSUs"), performance units ("PUs") and shares of stock issued under our employee stock purchase plan ("ESPP") (together, "Employee Stock-Based Awards").

Stock-based compensation expense for Employee Stock-Based Awards included in the accompanying Consolidated Statements of Operations for the three and six months ended June 30, 2014 was $7,317 ($5,417 after tax or $0.03 per basic and diluted share) and $14,458 ($10,551 after tax or $0.05 per basic and diluted share), respectively. Stock-based compensation expense for Employee Stock-Based Awards for the three and six months ended June 30, 2015 was $7,921 ($5,467 after tax or $0.03 per basic and diluted share) and $14,777 ($10,413 after tax or $0.05 per basic and diluted share), respectively.

Stock-based compensation expense for Employee Stock-Based Awards included in the accompanying Consolidated Statements of Operations related to continuing operations is as follows:

	Three Months Ended June 30,				Six Months Ended June 30,
	2014		2015		2014		2015
Cost of sales (excluding depreciation and amortization)	$	189	$	46	$	379	$	91
Selling, general and administrative expenses	7,128		7,875		14,079		14,686
Total stock-based compensation	$	7,317	$	7,921	$	14,458	$	14,777

The benefits associated with the tax deductions in excess of recognized compensation cost are required to be reported as financing activities in the accompanying Consolidated Statements of Cash Flows. This requirement reduces reported operating cash flows and increases reported financing cash flows. As a result, net financing cash flows from continuing operations included $(66) and $260 for the six months ended June 30, 2014 and 2015, respectively, from the (deficiency) benefit of tax deductions compared to recognized compensation cost. The tax benefit of any resulting excess tax deduction increases the Additional Paid-in Capital ("APIC") pool. Any resulting tax deficiency is deducted from the APIC pool.

Stock Options

Under our various stock option plans, options are generally granted with exercise prices equal to the market price of the stock on the date of grant; however, in certain instances, options are granted at prices greater than the market price of the stock on the date of grant. Certain of the options we issue become exercisable ratably over a period of ten years from the date of grant and have a contractual life of 12 years from the date of grant, unless the holder's employment is terminated sooner. As of June 30, 2015, ten-year vesting options represented 7.4% of total outstanding options. Certain of the options we issue become exercisable ratably over a period of five years from the date of grant and have a contractual life of ten years from the date of grant, unless the holder's employment is terminated sooner. As of June 30, 2015, five-year vesting options represented 46.1% of total outstanding options. The remainder of options we issue become exercisable ratably over a period of three years from the date of grant and have a contractual life of ten years from the date of grant, unless the holder's employment is terminated sooner. As of June 30, 2015, three-year vesting options represented 46.5% of total outstanding options. Our non-employee directors are considered employees for purposes of our stock option plans and stock option reporting. Options granted to our non-employee directors become exercisable immediately upon grant.

The weighted average fair value of options granted for the six months ended June 30, 2014 and 2015 was $5.60 and $4.99 per share, respectively. These values were estimated on the date of grant using the Black-Scholes option pricing model. The weighted average assumptions used for grants in the respective period are as follows:

	Six Months Ended June 30,
Weighted Average Assumptions	2014		2015
Expected volatility	33.9	%	28.6	%
Risk-free interest rate	2.06	%	1.70	%
Expected dividend yield	4	%	5	%
Expected life	6.8 years		5.5 years

Expected volatility is calculated utilizing daily historical volatility over a period that equates to the expected life of the option. The risk-free interest rate was based on the United States Treasury interest rates whose term is consistent with the expected life of the stock options. Expected dividend yield is considered in the option pricing model and represents our current annualized expected per share dividends over the current trade price of our common stock. The expected life (estimated period of time outstanding) of the stock options granted is estimated using the historical exercise behavior of employees.

A summary of option activity for the six months ended June 30, 2015 is as follows:

	Options		Weighted Average Exercise Price		Weighted Average Remaining Contractual Term (Years)	Average Intrinsic Value
Outstanding at December 31, 2014	3,678,246		$	23.37
Granted	696,722		43.64

Restricted Stock and Restricted Stock Units

Under our various equity compensation plans, we may also grant restricted stock or RSUs. Our restricted stock and RSUs generally have a vesting period of between three and five years from the date of grant. However, beginning in 2015, RSUs granted to our non-employee directors now vest immediately upon grant. All RSUs accrue dividend equivalents associated with the underlying stock as we declare dividends. Dividends will generally be paid to holders of RSUs in cash upon the vesting date of the associated RSU and will be forfeited if the RSU does not vest. The fair value of restricted stock and RSUs is the excess of the market price of our common stock at the date of grant over the purchase price (which is typically zero).

Cash dividends accrued and paid on RSUs for the three and six months ended June 30, 2014 and 2015 are as follows:

	Three Months Ended June 30,				Six Months Ended June 30,
	2014		2015		2014		2015
Cash dividends on RSUs accrued	$	416	$	631	$	850	$	1,301

Performance Units

Under our various equity compensation plans, we may also make awards of PUs. For the majority of PUs, the number of PUs earned is determined based on our performance against predefined targets of revenue or revenue growth and return on invested capital ("ROIC"). The number of PUs earned may range from 0% to 150% (for PUs granted prior to 2014) and 0% to 200% (for PUs granted in 2014 and thereafter) 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 either the one-year performance period (for PUs granted prior to 2014) or the three-year performance period (for PUs granted in 2014 and thereafter). Certain PUs granted in 2013, 2014 and 2015 will be earned based on a market condition associated with the total return on our common stock in relation to a subset of the S&P 500 rather than the revenue growth and ROIC targets noted above. The number of PUs earned based on this market condition may range from 0% to 200% of the initial award. All of our PUs will be settled in shares of our common stock and are subject to cliff vesting three years from the date of the original PU grant. For those PUs subject to a one-year performance period, employees who subsequently terminate their employment after the end of the one-year performance period and on or after attaining age 55 and completing 10 years of qualifying service (the "Retirement Criteria") shall immediately and completely vest in any PUs earned based on the actual achievement against the predefined targets as discussed above (but delivery of the shares remains deferred). As a result, PUs subject to a one-year performance period are generally expensed over the shorter of (1) the vesting period, (2) achievement of the Retirement Criteria, which may occur as early as January 1 of the year following the year of grant or (3) a maximum of three years. For those PUs subject to a three-year performance period, employees who terminate their employment during the performance period and on or after meeting the Retirement Criteria are eligible for pro rated vesting, subject to the actual achievement against the predefined targets as discussed above, based on the number of full years of service completed following the grant date (but delivery of the shares remains deferred). As a result, PUs subject to a three-year performance period are generally expensed over the three-year performance period. Outstanding PUs accrue dividend equivalents associated with the underlying stock as we declare dividends. Dividends will generally be paid to holders of PUs in cash upon the settlement date of the associated PU and will be forfeited if the PU does not vest.

Cash dividends accrued and paid on PUs for the three and six months ended June 30, 2014 and 2015 are as follows:

	Three Months Ended June 30,				Six Months Ended June 30,
	2014		2015		2014		2015
Cash dividends on PUs accrued	$	142	$	214	$	292	$	425
Cash dividends on PUs paid	91		—		312		1,015

During the six months ended June 30, 2015, we issued 139,446 PUs. The majority of our PUs are earned based on our performance against revenue or revenue growth and ROIC targets during their applicable performance period; therefore, we forecast the likelihood of achieving the predefined revenue, revenue growth and ROIC 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 applicable performance period) or the actual PUs earned (at the one-year anniversary date for PUs granted prior to 2014, and at the three-year anniversary date for PUs granted in 2014 and thereafter) over the vesting period for each of the awards. For PUs earned based on a market condition, we utilized 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, 2015, we expected 25% and 100% achievement of the predefined revenue, revenue growth and ROIC targets associated with the awards of PUs made in 2014 and 2015, respectively.

The fair value of earned PUs that vested during the three and six months ended June 30, 2014 and 2015 is as follows:

	Three Months Ended June 30,				Six Months Ended June 30,
	2014		2015		2014		2015
Fair value of earned PUs that vested	$	2,266	$	44	$	6,296	$	2,107

A summary of PU activity for the six months ended June 30, 2015 is as follows:

	Original PU Awards		PU Adjustment(1)		Total PU Awards		Weighted- Average Grant-Date Fair Value
Non-vested at December 31, 2014	461,666		(82,609	)	379,057		$	30.80

(1) Represents an increase or decrease in the number of original PUs awarded based on either (a) the final performance criteria achievement at the end of the defined performance period of such PUs or (b) a change in estimated awards based on the forecasted performance against the predefined targets.

Employee Stock Purchase Plan

We offer an ESPP in which participation is available to substantially all United States and Canadian employees who meet certain service eligibility requirements. The ESPP provides a way for our eligible employees to become stockholders on favorable terms. The ESPP provides for the purchase of our common stock by eligible employees through successive offering periods. We have historically had twosix-month offering periods per year, the first of which generally runs from June 1 through November 30 and the second of which generally runs from December 1 through May 31. During each offering period, participating employees accumulate after-tax payroll contributions, up to a maximum of 15% of their compensation, to pay the purchase price at the end of the offering. Participating employees may withdraw from an offering before the purchase date and obtain a refund of the amounts withheld as payroll deductions. At the end of the offering period, outstanding options under the ESPP are exercised, and each employee's accumulated contributions are used to purchase our common stock. The price for shares purchased under the ESPP is 95% of the fair market price at the end of the offering period, without a look-back feature. As a result, we do not recognize compensation expense for the ESPP shares purchased. For the six months ended June 30, 2014 and 2015, there were 69,567 shares and 59,569 shares, respectively, purchased under the ESPP. As of June 30, 2015, we have 901,069 shares available under the ESPP.

_______________________________________________________________________________

As of June 30, 2015, unrecognized compensation cost related to the unvested portion of our Employee Stock-Based Awards was $46,910 and is expected to be recognized over a weighted-average period of 2.2 years.

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

Income (Loss) Per Share-Basic and Diluted

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 options, warrants or convertible securities) that were outstanding during the period, unless the effect is antidilutive.

Revenues

Revenues

Our revenues consist of storage rental revenues as well as service revenues and are reflected net of sales and value added taxes. Storage rental revenues, which are considered a key driver of financial performance for the storage and information management services industry, consist primarily of recurring periodic rental charges related to the storage of materials or data (generally on a per unit basis). Service revenues include charges for related service activities, which include: (1) the handling of records, including the addition of new records, temporary removal of records from storage, refiling of removed records and the destruction of records; (2) courier operations, consisting primarily of the pickup and delivery of records upon customer request; (3) secure shredding of sensitive documents and the related sale of recycled paper, the price of which can fluctuate from period to period; (4) other services, including the scanning, imaging and document conversion services of active and inactive records, or Document Management Solutions ("DMS"), which relate to physical and digital records, and project revenues; (5) customer termination and permanent withdrawal fees; (6) data restoration projects; (7) special project work; (8) Fulfillment Services; (9) consulting services; and (10) Intellectual Property Management and other technology services and product sales (including specially designed storage containers and related supplies).

We recognize revenue when the following criteria are met: persuasive evidence of an arrangement exists, services have been rendered, the sales price is fixed or determinable and collectability of the resulting receivable is reasonably assured. 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. Amounts related to future storage rental or prepaid service contracts for customers where storage rental fees or services are billed in advance are accounted for as deferred revenue and recognized ratably over the period the applicable storage rental or service is provided or performed. Revenues from the sales of products, which are included as a component of service revenues, are recognized when products are shipped and title has passed to the customer. Revenues from the sales of products have historically not been significant.

Allowance for Doubtful Accounts and Credit Memo Reserves

Allowance for Doubtful Accounts and Credit Memo Reserves

We maintain an allowance for doubtful accounts and credit memos for estimated losses resulting from the potential inability of our customers to make required payments and potential disputes regarding billing and service issues. When calculating the allowance, we consider our past loss experience, current and prior trends in our aged receivables and credit memo activity, current economic conditions and specific circumstances of individual receivable balances. If the financial condition of our customers were to significantly change, resulting in a significant improvement or impairment of their ability to make payments, an adjustment of the allowance may be required. We charge-off uncollectible balances as circumstances warrant, generally, no later than one year past due.

Income Taxes

Income Taxes

As noted previously, we have been organized and operating as a REIT effective for our taxable year beginning January 1, 2014. As a REIT, we are generally permitted to deduct from our federal taxable income the dividends we pay to our stockholders. The income represented by such dividends is not subject to federal taxation at the entity level but may be taxed at the stockholder level. The income of our domestic taxable REIT subsidiaries (“TRSs”), which hold our domestic operations that may not be REIT‑compliant as currently operated and structured, is subject, as applicable, to federal and state corporate income tax. In addition, we and our subsidiaries continue to be subject to foreign income taxes in jurisdictions in which we have business operations or a taxable presence, regardless of whether assets are held or operations are conducted through subsidiaries disregarded for federal tax purposes or as TRSs. We will also be subject to a separate corporate income tax on any gains recognized during a specified period (generally ten years) following the REIT conversion that are attributable to “built‑in” gains with respect to the assets that we owned on January 1, 2014; this built‑in gains tax has been imposed on our depreciation recapture recognized into income in 2014 and generally will be imposed in subsequent years as a result of accounting method changes commenced in our pre‑REIT period. If we fail to remain qualified for taxation as a REIT, we will be subject to federal income tax at regular corporate tax rates. Even if we remain qualified for taxation as a REIT, we may be subject to some federal, state, local and foreign taxes on our income and property in addition to taxes owed with respect to our TRS operations. In particular, while state income tax regimes often parallel the federal income tax regime for REITs, many states do not completely follow federal rules and some do not follow them at all.

We provide for income taxes during interim periods based on our estimate of the effective tax rate for the year. Discrete items and changes in our estimate of the annual effective tax rate are recorded in the period they occur. Our effective tax rate is subject to variability in the future due to, among other items: (1) changes in the mix of income between our qualified REIT subsidiaries and our TRSs, as well as between 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. We are subject to income taxes in the United States and numerous foreign jurisdictions. We are subject to examination by various tax authorities in jurisdictions in which we have business operations or a taxable presence. We regularly assess the likelihood of additional assessments by tax authorities and provide for these matters as appropriate. Although we believe our tax estimates are appropriate, the final determination of tax audits and any related litigation could result in changes in our estimates.

Accounting for income taxes requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the tax and financial reporting bases of assets and liabilities and for loss and credit carryforwards. Valuation allowances are provided when recovery of deferred tax assets does not meet the more likely than not standard as defined in GAAP.

We have elected to recognize interest and penalties associated with uncertain tax positions as a component of the provision (benefit) for income taxes in the accompanying Consolidated Statements of Operations. We recorded a decrease of $631 and an increase of $335 for gross interest and penalties for the three and six months ended June 30, 2014, respectively. We recorded an increase of $637 and $1,579 for gross interest and penalties for the three and six months ended June 30, 2015, respectively. We had $5,884 and $6,756 accrued for the payment of interest and penalties as of December 31, 2014 and June 30, 2015, respectively.

As a result of our REIT conversion, we recorded a net tax benefit of $230,051 and $212,151 during the three and six months ended June 30, 2014, respectively, for the revaluation of certain deferred tax assets and liabilities and other income taxes associated with the REIT conversion. The other primary reconciling items between the federal statutory rate of 35% and our overall effective tax rate in the three and six months ended June 30, 2014 were a $36,084 increase in our tax provision recognized in the second quarter of 2014 associated with incremental federal and state income taxes and foreign withholding taxes on earnings of our foreign subsidiaries no longer considered permanently invested and other net tax benefit related to the REIT conversion of $18,763 and $33,835, respectively, primarily related to the dividends paid deduction.

Our effective tax rates for the three and six months ended June 30, 2015 were 12.1% and 19.6%, respectively. The primary reconciling items between the federal statutory rate of 35% and our overall effective tax rate in the three and six months ended June 30, 2015 were the benefit derived from the dividends paid deduction, differences in the rates of tax at which our foreign earnings are subject, including foreign exchange gains and losses in different jurisdictions with different tax rates and state income taxes (net of federal tax benefit).

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

Fair Value Measurements

    Fair Value Measurements

Entities are permitted under GAAP to elect to measure many financial instruments and certain other items at either fair value or cost. We did not elect the fair value measurement option.

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

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

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

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

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

Use of Estimates

    Use of Estimates

The preparation of financial statements in conformity with GAAP requires us to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities at the date of the financial statements and for the period then ended. On an ongoing basis, we evaluate the estimates used. We base our estimates on historical experience, actuarial estimates, current conditions and various other assumptions that we believe to be reasonable under the circumstances. These estimates form the basis for making judgments about the carrying values of assets and liabilities and are not readily apparent from other sources. Actual results may differ from these estimates

Property, Plant and Equipment and Long-Lived Assets

Property, Plant and Equipment and Long-Lived Assets

We develop various software applications for internal use. Computer software costs associated with internal use software are expensed as incurred until certain capitalization criteria are met. Payroll and related costs for employees directly associated with, and devoting time to, the development of internal use computer software projects (to the extent time is spent directly on the project) are capitalized. During the three and six months ended June 30, 2014, we capitalized $4,861 and $9,758 of costs, respectively, associated with the development of internal use computer software projects. During the three and six months ended June 30, 2015, we capitalized $6,395 and $12,435 of costs, respectively, associated with the development of internal use computer software projects. Capitalization begins when the design stage of the application has been completed and it is probable that the project will be completed and used to perform the function intended. Capitalization ends when the asset is ready for its intended use. Depreciation begins when the software is placed in service. Computer software costs that are capitalized are periodically evaluated for impairment.

We review long-lived assets and all amortizable intangible assets for impairment whenever events or changes in circumstances indicate the carrying amount of such assets may not be recoverable. Recoverability of these assets is determined by comparing the forecasted undiscounted net cash flows of the operation to which the assets relate to their carrying amount. The operations are generally distinguished by the business segment and geographic region in which they operate. If the operation is determined to be unable to recover the carrying amount of its assets, the long-lived assets are written down, on a pro rata basis, to fair value. Fair value is determined based on discounted cash flows or appraised values, depending upon the nature of the assets.

As a result of our conversion to a REIT and in accordance with SEC rules applicable to REITs, we no longer report (gain) loss on the sale of real estate as a component of operating income, but we report it as a component of income (loss) from continuing operations. We report the (gain) loss on sale of property, plant and equipment (excluding real estate), along with any impairment, write-downs or involuntary conversions related to real estate, as a component of operating income. Previously reported amounts have been reclassified to conform to this presentation.

Recent Accounting Pronouncements

New Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU 2014-09"). ASU 2014-09 provides additional 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, (3) licenses, (4) time value of money and (5) contract costs. Further disclosures will be required to provide a better understanding of revenue that has been recognized and revenue that is expected to be recognized in the future from existing contracts. In July 2015, the FASB deferred the effective date of ASU 2014-09 for one year, making it effective for our year beginning January 1, 2018, with early adoption permitted as of January 1, 2017. We are currently evaluating the impact ASU 2014-09 will have on our consolidated financial statements.

In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements Going Concern (Subtopic 205-40) (“ASU 2014-15”). ASU 2014-15 requires management to assess an entity’s ability to continue as a going concern by incorporating and expanding upon certain principles of current United States auditing standards. Specifically, the amendments (1) provide a definition of the term “substantial doubt”, (2) require an evaluation every reporting period, including interim periods, (3) provide principles for considering the mitigating effect of management’s plans, (4) require certain disclosures when substantial doubt is alleviated as a result of consideration of management’s plans, (5) require an express statement and other disclosures when substantial doubt is still present, and (6) require an assessment for a period of one year after the date that the financial statements are issued (or available to be issued). ASU 2014‑15 is effective for us on January 1, 2017, with early adoption permitted. We do not believe that this pronouncement will have an impact on our consolidated financial statements.

In February 2015, the FASB issued ASU No. 2015‑02, Consolidation (Topic 810): Amendments to the Consolidation Analysis (“ASU 2015‑02”). ASU 2015‑02 affects reporting entities that are required to evaluate whether they should consolidate certain legal entities. ASU 2015‑02 is effective for us on January 1, 2016, with early adoption permitted. We do not believe that this pronouncement will have an impact on our consolidated financial statements.

In April 2015, the FASB issued ASU No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs (“ASU 2015-03”).  The amendments in ASU 2015-03 require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts.  The recognition and measurement guidance for debt issuance costs are not affected by the amendments in ASU 2015-03.  ASU 2015‑03 is effective for us on January 1, 2016, with early adoption permitted.  We do not believe that this pronouncement will have a material impact on our consolidated financial statements.

Subsequent Events

Credit Agreement

On July 2, 2015, we entered into a new credit agreement (the "New Credit Agreement") to refinance the Credit Agreement which was scheduled to terminate on June 27, 2016. The New Credit Agreement consists of a revolving credit facility (the "New Revolving Credit Facility") and a term loan (the "New Term Loan"). The New Credit Agreement is supported by a group of 25 banks.

At the time we entered into the New Credit Agreement, we borrowed $846,231 and $250,000 under the New Revolving Credit Facility and the New Term Loan, respectively, and used such borrowings to repay outstanding balances under the Credit Agreement, including the full amount due on the IMI Term Loan. Before such repayment, there was $1,099,117 outstanding under the Credit Agreement.

The New Revolving Credit Facility, consistent with the IMI Revolving Credit Facility, enables IMI and certain of its United States and foreign subsidiaries to borrow in United States dollars and (subject to sublimits) a variety of other currencies(including Canadian dollars, British pounds sterling, Euros and Australian dollars, among other currencies) in an aggregate outstanding amount not to exceed $1,500,000. Commencing on September 30, 2015, the New Term Loan will begin to amortize in quarterly installments in an amount equal to $3,125 per quarter, with the remaining balance due on July 3, 2019. The New Credit Agreement includes an option to allow us to request additional commitments of up to $500,000, in the form of term loans or through increased commitments under the New Revolving Credit Facility, subject to the conditions as defined in the New Credit Agreement.

In addition, IMI and the Guarantors continue to guarantee all the obligations under the New Credit Agreement and, similar to the Credit Agreement, the New Credit Agreement contains 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 New Credit Agreement terminates on July 6, 2019, at which point all obligations become due, but may be extended by one year at our option, subject to the conditions set forth in the New Credit Agreement. Borrowings under the New Credit Agreement may be prepaid without penalty or premium, in whole or in part, at any time.

A debt extinguishment charge of approximately $2,300 will be recorded to other expense (income), net in the third quarter of 2015 related to the refinancing of the Credit Agreement, representing a write-off of unamortized deferred financing costs.

Overhead Optimization Plan

In the third quarter of 2015, we implemented a plan that calls for certain organizational realignments to reduce our overhead costs, particularly in our developed markets, in order to optimize our selling, general and administrative cost structure and to support investments to advance our growth strategy. As a result of these realignments, we expect to record a charge of approximately $10,000 in the third quarter of 2015. This charge primarily relates to employee severance and associated benefits.
