Organization, Consolidation and Presentation of Financial Statements [Abstract]
General	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.

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 7 1 / 4 % GBP Senior Subordinated Notes due 2014 (the "7 1 / 4 % Notes"), (2) our 6 3 / 4 % Euro Senior Subordinated Notes due 2018 (the "6 3 / 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 Six Months Ended 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 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 Emerging Businesses(3) — New Western Europe(4) 354,049 Emerging Markets - Eastern Europe(5) 87,408 Latin America(5) 107,240 Australia and Singapore(5) 55,779 Greater China(5) 3,500 India(5) — Russia, Ukraine and Denmark(5) 628 Total $ 2,423,783 _______________________________________________________________________________ (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 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 North American Western European Business Other International Business Corporate and Other Business Total Gross Balance as of December 31, 2014 $ 1,645,209 $ 429,982 $ 412,322 $ 254,706 $ — $ 2,742,219 Deductible goodwill acquired during the year 1,638 409 — — 3,036 5,083 Non-deductible goodwill acquired during the year 239 24 1,241 1,764 — 3,268 Fair value and other adjustments(1) 99 (25 ) (365 ) (1,111 ) — (1,402 ) Currency effects (11,163 ) (2,800 ) (9,155 ) (21,062 ) — (44,180 ) Gross Balance as of June 30, 2015 $ 1,636,022 $ 427,590 $ 404,043 $ 234,297 $ 3,036 $ 2,704,988 Accumulated Amortization Balance as of December 31, 2014 $ 205,987 $ 54,025 $ 58,273 $ 151 $ — $ 318,436 Currency effects (532 ) (133 ) (1,471 ) (9 ) — (2,145 ) Accumulated Amortization Balance as of June 30, 2015 $ 205,455 $ 53,892 $ 56,802 $ 142 $ — $ 316,291 Net Balance as of December 31, 2014 $ 1,439,222 $ 375,957 $ 354,049 $ 254,555 $ — $ 2,423,783 Net Balance as of June 30, 2015 $ 1,430,567 $ 373,698 $ 347,241 $ 234,155 $ 3,036 $ 2,388,697 Accumulated Goodwill Impairment Balance as of December 31, 2014 $ 85,909 $ — $ 46,500 $ — $ — $ 132,409 Accumulated Goodwill Impairment Balance as of June 30, 2015 $ 85,909 $ — $ 46,500 $ — $ — $ 132,409 _______________________________________________________________________________ (1) Total fair value and other adjustments primarily include $672 in net adjustments to deferred income taxes and $(5,680) related to customer relationships and acquisition costs and other assumed liabilities, as well as $3,606 of cash paid related to certain 2014 acquisitions. The components of our amortizable intangible assets as of December 31, 2014 and June 30, 2015 are as follows: December 31, 2014 June 30, 2015 Gross Carrying Accumulated Net Carrying Gross Carrying Accumulated Net Carrying Customer Relationships and Acquisition Costs $ 904,866 $ (297,029 ) $ 607,837 $ 913,523 $ (318,055 ) $ 595,468 Core Technology(1) 3,568 (3,540 ) 28 3,414 (3,414 ) — Trademarks and Non-Compete Agreements(1) 7,062 (5,068 ) 1,994 6,908 (5,086 ) 1,822 Deferred Financing Costs 63,033 (15,956 ) 47,077 63,805 (19,978 ) 43,827 Total $ 978,529 $ (321,593 ) $ 656,936 $ 987,650 $ (346,533 ) $ 641,117 _______________________________________________________________________________ (1) Included in Other, a component of Other Assets, net in the accompanying Consolidated Balance Sheets. 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 Six Months Ended 2014 2015 2014 2015 Amortization expense associated with amortizable intangible assets (including deferred financing costs) $ 14,332 $ 13,593 $ 27,958 $ 26,845 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 Six Months Ended 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 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 Weighted Average Outstanding at December 31, 2014 3,678,246 $ 23.37 Granted 696,722 43.64 Exercised (350,910 ) 21.03 Forfeited (20,729 ) 23.63 Expired (11,045 ) 22.15 Outstanding at June 30, 2015 3,992,284 $ 27.11 5.74 $ 24,551 Options exercisable at June 30, 2015 2,728,453 $ 22.67 4.30 $ 22,715 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 Six Months Ended 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 Six Months Ended 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 Six Months Ended 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 Weighted- 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 Six Months Ended 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 Six Months Ended 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 Adjustment(1) Total Weighted- Non-vested at December 31, 2014 461,666 (82,609 ) 379,057 $ 30.80 Granted 139,446 — 139,446 40.38 Vested (80,035 ) (4,350 ) (84,385 ) 29.62 Forfeited (19,038 ) — (19,038 ) 30.96 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 two six -month offering periods per year, the first of which generally runs from June 1 through November 30 and the second of which generally runs from December 1 through May 31. During each offering period, participating employees accumulate after-tax payroll contributions, up to a maximum of 15% of their compensation, to pay the purchase price at the end of the offering. Participating employees may withdraw from an offering before the purchase date and obtain a refund of the amounts withheld as payroll deductions. At the end of the offering period, outstanding options under the ESPP are exercised, and each employee's accumulated contributions are used to purchase our common stock. The price for shares purchased under the ESPP is 95% of the fair market price at the end of the offering period, without a look-back feature. As a result, we do not recognize compensation expense for the ESPP shares purchased. For the 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 Six Months Ended 2014 2015 2014 2015 Income (loss) from continuing operations $ 272,702 $ 54,007 $ 315,423 $ 95,746 Total (loss) income from discontinued operations $ (326 ) $ — $ (938 ) $ — Net income (loss) attributable to Iron Mountain Incorporated $ 271,637 $ 53,330 $ 313,304 $ 94,426 Weighted-average shares—basic 192,381,000 210,699,000 192,130,000 210,468,000 Effect of dilutive potential stock options 762,416 958,714 722,609 1,091,022 Effect of dilutive potential restricted stock, RSUs and PUs 382,317 419,002 444,968 603,880 Weighted-average shares—diluted 193,525,733 212,076,716 193,297,577 212,162,902 Earnings (losses) per share—basic: Income (loss) from continuing operations $ 1.42 $ 0.26 $ 1.64 $ 0.45 Total (loss) income from discontinued operations $ — $ — $ — $ — Net income (loss) attributable to Iron Mountain Incorporated—basic $ 1.41 $ 0.25 $ 1.63 $ 0.45 Earnings (losses) per share—diluted: Income (loss) from continuing operations $ 1.41 $ 0.25 $ 1.63 $ 0.45 Total (loss) income from discontinued operations $ — $ — $ — $ — Net income (loss) attributable to Iron Mountain Incorporated—diluted $ 1.40 $ 0.25 $ 1.62 $ 0.45 Antidilutive stock options, RSUs and PUs, excluded from the calculation 1,457,975 1,335,373 1,419,469 846,803 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

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 Six Months Ended 2014 2015 2014 2015 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: Asset Derivatives December 31, 2014 June 30, 2015 Derivatives Not Designated as Balance Sheet Fair Balance Sheet Fair Foreign exchange contracts Prepaid expenses and other $ — Prepaid expenses and other $ 6,362 Total $ — $ 6,362 Liability Derivatives December 31, 2014 June 30, 2015 Derivatives Not Designated as Balance Sheet Fair Balance Sheet Fair Foreign exchange contracts Accrued expenses $ 2,411 Accrued expenses $ — Total $ 2,411 $ — Amount of (Gain) Three Months Ended June 30, Six Months Ended June 30, Derivatives Not Designated as Location of (Gain) Loss 2014 2015 2014 2015 Foreign exchange contracts Other expense (income), net $ 11,748 $ (8,119 ) $ 14,670 $ 20,414 Total $ 11,748 $ (8,119 ) $ 14,670 $ 20,414 We have designated a portion of the 6 3 / 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 6 3 / 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 Six Months Ended 2014 2015 2014 2015 Foreign exchange gains (losses) $ 663 $ (1,464 ) $ 808 $ 3,466 Tax expense (benefit) on foreign exchange gains (losses) — — 57 — Foreign exchange gains (losses), net of tax $ 663 $ (1,464 ) $ 751 $ 3,466 As of June 30, 2015 , cumulative net gains of $17,278 , net of tax are recorded in accumulated other comprehensive items, net associated with this net investment hedge.

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.

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

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.

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.

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.

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 Record Date Total 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 September 15, 2014 (1) 3.6144 September 30, 2014 700,000 November 4, 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 _______________________________________________________________________________ (1) Represents Special Distribution.

Subsequent Events [Abstract]
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.

Summary of Significant Accoun21

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 7 1 / 4 % GBP Senior Subordinated Notes due 2014 (the "7 1 / 4 % Notes"), (2) our 6 3 / 4 % Euro Senior Subordinated Notes due 2018 (the "6 3 / 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 Six Months Ended 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 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 Weighted Average Outstanding at December 31, 2014 3,678,246 $ 23.37 Granted 696,722 43.64 Exercised (350,910 ) 21.03 Forfeited (20,729 ) 23.63 Expired (11,045 ) 22.15 Outstanding at June 30, 2015 3,992,284 $ 27.11 5.74 $ 24,551 Options exercisable at June 30, 2015 2,728,453 $ 22.67 4.30 $ 22,715 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 Six Months Ended 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 Six Months Ended 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 Six Months Ended 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 Weighted- 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 Six Months Ended 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 Six Months Ended 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 Adjustment(1) Total Weighted- Non-vested at December 31, 2014 461,666 (82,609 ) 379,057 $ 30.80 Granted 139,446 — 139,446 40.38 Vested (80,035 ) (4,350 ) (84,385 ) 29.62 Forfeited (19,038 ) — (19,038 ) 30.96 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 two six -month offering periods per year, the first of which generally runs from June 1 through November 30 and the second of which generally runs from December 1 through May 31. During each offering period, participating employees accumulate after-tax payroll contributions, up to a maximum of 15% of their compensation, to pay the purchase price at the end of the offering. Participating employees may withdraw from an offering before the purchase date and obtain a refund of the amounts withheld as payroll deductions. At the end of the offering period, outstanding options under the ESPP are exercised, and each employee's accumulated contributions are used to purchase our common stock. The price for shares purchased under the ESPP is 95% of the fair market price at the end of the offering period, without a look-back feature. As a result, we do not recognize compensation expense for the ESPP shares purchased. For the 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.

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 Six Months Ended 2014 2015 2014 2015 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.

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 .
