At the closing of the Recall Transaction, we paid approximately $331,800 in cash and issued 50,233,412 shares of our common stock which, based on the closing price of our common stock as of April 29, 2016 (the last day of trading on the New York Stock Exchange ("NYSE") prior to the closing of the Recall Transaction) of $36.53 per share, resulted in a total purchase price to Recall shareholders of approximately $2,166,900 .

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	a. Principles of Consolidation The accompanying financial statements reflect our financial position, results of operations, comprehensive income (loss), equity and cash flows on a consolidated basis. All intercompany transactions and account balances have been eliminated. b. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America ("GAAP") requires us to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities at the date of the financial statements and for the period then ended. On an ongoing basis, we evaluate the estimates used. We base our estimates on historical experience, actuarial estimates, current conditions and various other assumptions that we believe to be reasonable under the circumstances. These estimates form the basis for making judgments about the carrying values of assets and liabilities and are not readily apparent from other sources. Actual results may differ from these estimates. c. 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. d. 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 Europe, 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 (i) our previously outstanding 7 1 / 4 % GBP Senior Subordinated Notes due 2014 (the "7 1 / 4 % Notes"), (ii) our previously outstanding 6 3 / 4 % Euro Senior Subordinated Notes due 2018 (the "6 3 / 4 % Notes"), (iii) borrowings in certain foreign currencies under our Revolving Credit Facility and our Former Revolving Credit Facility (each as defined in Note 4) and (iv) 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. The total loss on foreign currency transactions for the years ended December 31, 2014 , 2015 and 2016 is as follows: Year Ended December 31, 2014 2015 2016 Total loss on foreign currency transactions $ 58,316 $ 70,851 $ 20,413 e. Derivative Instruments and Hedging Activities Every derivative instrument is required to be recorded in the balance sheet as either an asset or a liability measured at its fair value. Periodically, we acquire derivative instruments that are intended to hedge either cash flows or values that are subject to foreign exchange or other market price risk and not for trading purposes. We have formally documented our hedging relationships, including identification of the hedging instruments and the hedged items, as well as our risk management objectives and strategies for undertaking each hedge transaction. Given the recurring nature of our revenues and the long-term nature of our asset base, we have the ability and the preference to use long-term, fixed interest rate debt to finance our business, thereby preserving our long-term returns on invested capital. We target approximately 75% of our debt portfolio to be fixed with respect to interest rates. Occasionally, we may use interest rate swaps as a tool to maintain our targeted level of fixed rate debt. In addition, we may use borrowings in foreign currencies, either obtained in the United States or by our foreign subsidiaries, to hedge foreign currency risk associated with our international investments. Sometimes we enter into currency swaps to temporarily hedge an overseas investment, such as a major acquisition, while we arrange permanent financing or to hedge our exposure due to foreign currency exchange movements related to our intercompany accounts with and between our foreign subsidiaries. As of December 31, 2015 and 2016, we had no forward contracts outstanding. f. Property, Plant and Equipment Property, plant and equipment are stated at cost and depreciated using the straight-line method with the following useful lives (in years): Range Buildings and building improvements 5 to 40 Leasehold improvements 5 to 10 or life of the lease (whichever is shorter) Racking 1 to 20 or life of the lease (whichever is shorter) Warehouse equipment/vehicles 1 to 10 Furniture and fixtures 1 to 10 Computer hardware and software 2 to 5 Property, plant and equipment (including capital leases in the respective category), at cost, consist of the following: December 31, 2015 2016 Land $ 218,174 $ 260,059 Buildings and building improvements 1,507,224 1,702,448 Leasehold improvements 447,449 538,368 Racking 1,556,749 1,875,771 Warehouse equipment/vehicles 335,728 395,595 Furniture and fixtures 50,307 52,836 Computer hardware and software 515,688 588,980 Construction in progress 112,917 121,726 $ 4,744,236 $ 5,535,783 Minor maintenance costs are expensed as incurred. Major improvements which extend the life, increase the capacity or improve the safety or the efficiency of property owned are capitalized. Major improvements to leased buildings are capitalized as leasehold improvements and depreciated. 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 years ended December 31, 2014 , 2015 and 2016 , we capitalized $19,419 , $26,201 and $16,438 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. During the years ended December 31, 2014 and 2016, we wrote off previously deferred software costs associated with internal use software development projects that were discontinued after implementation, which resulted in a loss on disposal/write-down of property, plant and equipment (excluding real estate), net in the accompanying Consolidated Statements of Operations, by segment as follows: Year Ended December 31, 2014 2015 2016 North American Records and Information Management Business $ 1,000 $ — $ 1,833 North American Data Management Business — — — Western European Business 300 — — Other International Business — — — Corporate and Other Business — — — $ 1,300 $ — $ 1,833 Entities are required to record the fair value of a liability for an asset retirement obligation in the period in which it is incurred. Asset retirement obligations represent the costs to replace or remove tangible long-lived assets required by law, regulatory rule or contractual agreement. When the liability is initially recorded, the entity capitalizes the cost by increasing the carrying amount of the related long-lived asset, which is then depreciated over the useful life of the related asset. The liability is increased over time through accretion expense (included in depreciation expense) such that the liability will equate to the future cost to retire the long-lived asset at the expected retirement date. Upon settlement of the liability, an entity either settles the obligation for its recorded amount or realizes a gain or loss upon settlement. Our asset retirement obligations are primarily the result of requirements under our facility lease agreements which generally have "return to original condition" clauses which would require us to remove or restore items such as shred pits, vaults, demising walls and office build-outs, among others. The significant assumptions used in estimating our aggregate asset retirement obligation are the timing of removals, the probability of a requirement to perform, estimated cost and associated expected inflation rates that are consistent with historical rates and credit-adjusted risk-free rates that approximate our incremental borrowing rate. A reconciliation of liabilities for asset retirement obligations (included in other long-term liabilities) is as follows: December 31, 2015 2016 Asset Retirement Obligations, beginning of the year $ 12,897 $ 13,997 Liabilities Assumed — 10,678 Liabilities Incurred 1,030 687 Liabilities Settled (966 ) (1,106 ) Accretion Expense 1,241 1,587 Foreign Currency Translation Adjustments (205 ) (355 ) Asset Retirement Obligations, end of the year $ 13,997 $ 25,488 g. Long-Lived Assets We review long-lived assets, including all finite-lived intangible assets, for impairment whenever events or changes in circumstances indicate the carrying amount of such assets may not be recoverable. Recoverability of these assets is determined by comparing the forecasted undiscounted net cash flows of the operation to which the assets relate to their carrying amount. The operations are generally distinguished by the business segment and geographic region in which they operate. If it is determined that we are unable to recover the carrying amount of the assets, the long-lived assets are written down, on a pro rata basis, to fair value. Fair value is determined based on discounted cash flows or appraised values, depending upon the nature of the assets. Long-lived assets, including finite-lived intangible assets, are amortized over their useful lives. We annually, or more frequently if events or circumstances warrant, assess whether a change in the lives over which long-lived assets, including finite-lived intangible assets, are amortized is necessary. Consolidated loss on disposal/write-down of property, plant and equipment (excluding real estate), net was $1,065 for the year ended December 31, 2014 and consisted primarily of losses associated with the write-off of certain software associated with our North American Records and Information Management Business segment. Consolidated loss on disposal/write-down of property, plant and equipment (excluding real estate), net was $3,000 for the year ended December 31, 2015 and consisted primarily of approximately $1,800 of losses associated with the write-off of certain property in our Western European Business segment, as well as $1,500 of losses associated with the write-off of certain property in our North American Records and Information Management Business segment, partially offset by gains on the retirement of leased vehicles accounted for as capital lease assets primarily associated with our North American Records and Information Management Business segment. Consolidated loss on disposal/write-down of property, plant and equipment (excluding real estate), net was $1,412 for the year ended December 31, 2016 and consisted primarily of losses associated with the write-off of certain software assets associated with our North American Records and Information Management Business segment, partially offset by gains on the retirement of leased vehicles accounted for as capital lease assets primarily associated with our North American Records and Information Management Business segment. Gain on sale of real estate, net of tax, which consists primarily of the sale of land and buildings in the United Kingdom, United States and Canada, for the years ended December 31, 2014 , 2015 and 2016 is as follows: Year Ended December 31, 2014 2015 2016 Gain on sale of real estate $ 10,512 $ 1,059 $ 2,310 Tax effect on gain on sale of real estate (2,205 ) (209 ) (130 ) Gain on sale of real estate, net of tax $ 8,307 $ 850 $ 2,180 h. Goodwill and Other Indefinite-Lived Intangible Assets Goodwill and intangible assets with indefinite lives are not amortized but are reviewed annually for impairment or more frequently if impairment indicators arise. Other than goodwill, we currently have no intangible assets that have indefinite lives and which are not amortized. We have selected October 1 as our annual goodwill impairment review date. As described in more detail below, we performed our annual goodwill impairment review as of October 1, 2014 , 2015 and 2016 , and concluded that goodwill was not impaired as of such dates. As of December 31, 2016 , no factors were identified that would alter our October 1, 2016 goodwill impairment analysis. In making this assessment, we considered 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. Goodwill Impairment Analysis - 2015 Our reporting units at which level we performed our goodwill impairment analysis as of October 1, 2015 were as follows: (1) North American Records and Information Management; (2) North American Secure Shredding; (3) North American Data Management; (4) Adjacent Businesses - Data Centers (which consists primarily of our data center business in the United States); (5) Adjacent Businesses - Consumer Storage (which consists of a consumer storage business with operations in the United States acquired in April 2015); (6) the United Kingdom (including our operations in England, Northern Ireland and Scotland), Ireland and Norway (the "UKI and Norway" reporting unit); (7) Austria, Belgium, France, Germany, the Netherlands, Spain and Switzerland (the "Continental Western Europe" reporting unit); (8) the remaining countries in Europe in which we operate, excluding Russia, Ukraine and Denmark (the "Emerging Markets - Eastern Europe" reporting unit); (9) Latin America; (10) Australia and Singapore; (11) China (including Taiwan) and Hong Kong (the "Greater China" reporting unit); (12) India; and (13) Russia, Ukraine and Denmark. We concluded that the goodwill for each of our reporting units was not impaired as of such date. During the fourth quarter of 2015, as a result of changes in the management of certain of our businesses in Europe and Asia Pacific, we reassessed the composition of our reporting units as well as our reportable operating segments (see Note 9 for a description of our reportable operating segments). As part of this reassessment, we determined that our former Russia, Ukraine and Denmark reporting unit, as well as our business in Norway (which was previously managed along with our operations in the United Kingdom and Ireland within our UKI and Norway reporting unit) are being managed in conjunction with the businesses included in our Emerging Markets - Eastern Europe reporting unit. This reporting unit, which consists of (i) our former Emerging Markets - Eastern Europe reporting unit, (ii) our former Russia, Ukraine and Denmark reporting unit, and (iii) our business in Norway is referred to herein as the “Emerging Markets - Europe” reporting unit. Our businesses in the United Kingdom and Ireland are being managed as a separate reporting unit (the “UKI” reporting unit). Additionally, we determined that our business in Singapore, which was previously managed along with our operations in Australia, is being managed with our businesses in our Greater China reporting unit. This reporting unit, which consists of (i) our former Greater China reporting unit and (ii) our business in Singapore, is referred to herein as the "Southeast Asia" reporting unit. Our business in Australia was being managed on a standalone basis (the “Australia” reporting unit). 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 fourth quarter of 2015, we performed an interim goodwill impairment test, for the UKI, Emerging Markets - Europe, Australia and Southeast Asia reporting units. We concluded that the goodwill for each of these reporting units was not impaired as of such date. Additionally, in December 2015, we acquired Crozier Fine Arts ("Crozier"), a storage, logistics and transportation business for high value paintings, photographs and other types of art. We determined that Crozier will be managed as a separate component within our Adjacent Businesses operating segment and, therefore, constitutes a separate reporting unit (the "Adjacent Businesses - Fine Arts" reporting unit). Goodwill by Reporting Unit as of December 31, 2015 The carrying value of goodwill, net for each of our reporting units described above as of December 31, 2015 was as follows: Carrying Value as of December 31, 2015 North American Records and Information Management(1) $ 1,342,723 North American Secure Shredding(1) 73,021 North American Data Management(2) 369,907 Adjacent Businesses - Data Centers(3) — Adjacent Businesses - Consumer Storage(3) 4,636 Adjacent Businesses - Fine Arts(3) 21,550 UKI(4) 260,202 Continental Western Europe(4) 63,442 Emerging Markets - Europe(5) 87,378 Latin America(5) 78,537 Australia(5) 47,786 Southeast Asia(5) 5,683 India(5) 6,113 Total $ 2,360,978 _______________________________________________________________________________ (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. Goodwill Impairment Analysis - 2016 In the third quarter of 2016, as a result of changes in the management of our businesses included in our Western European Business segment, we reassessed the composition of our reporting units. As a result of this reassessment, we determined that the businesses included in our former UKI reporting unit were now being managed in conjunction with the businesses included in our former Continental Western Europe reporting unit. As a result, we concluded that our Western European Business segment consists of one reporting unit, which is referred to herein as the Western Europe reporting unit. The acquisitions we completed during the first nine months of 2016, which are more fully disclosed in Note 6, impacted our reporting units as of October 1, 2016 as follows: • North American Records and Information Management - includes the goodwill associated with the records and information management businesses of Recall in the United States and Canada. • North American Secure Shredding - includes the goodwill associated with the secure shredding businesses of Recall in the United States and Canada. • North American Data Management - includes the goodwill associated with the data management businesses of Recall in the United States and Canada. • Western Europe - includes the goodwill associated with the operations of Recall in Belgium, France, Germany, Spain, Switzerland and the United Kingdom as well as the goodwill associated with the Information Governance and Digital Solutions (formerly referred to as document management solutions, or DMS) operations of Recall in Sweden. • Northern and Eastern Europe - this reporting unit consists of our former Emerging Markets - Europe reporting unit and includes the goodwill associated with the operations of Recall in Denmark, Finland and Norway, as well as the goodwill associated with the records and information management operations of Recall in Sweden. This reporting unit also includes goodwill associated with our March 2016 acquisition of Archyvu Sistemos with operations in Lithuania, Latvia and Estonia. • Latin America - includes the goodwill associated with the operations of Recall in Brazil and Mexico. • Australia and New Zealand - this reporting unit consists of the goodwill associated with the Australia Retained Business (as defined in Note 6), which was a component of our former Australia reporting unit, as well as the operations of Recall in Australia and New Zealand. • Southeast Asia - includes the goodwill associated with the operations of Recall in China, Hong Kong, Malaysia, Singapore, Taiwan and Thailand. • Africa and India - includes the goodwill associated with the operations of Recall in India, as well as the goodwill associated with our March 2016 acquisition of Docufile Holdings Proprietary Limited with operations in South Africa. As a result of the changes described above, our reporting units at which level we performed our goodwill impairment analysis as of October 1, 2016 were as follows: (1) North American Records and Information Management; (2) North American Secure Shredding; (3) North American Data Management; (4) Adjacent Businesses - Data Centers; (5) Adjacent Businesses - Consumer Storage; (6) Adjacent Businesses - Fine Arts; (7) Western Europe; (8) Northern and Eastern Europe; (9) Latin America; (10) Australia and New Zealand; (11) Southeast Asia; and (12) Africa and India. We concluded that the goodwill for each of these reporting units was not impaired as of such date. Goodwill by Reporting Unit as of December 31, 2016 The carrying value of goodwill, net for each of our reporting units described above as of December 31, 2016 is as follows: Carrying Value North American Records and Information Management(1) $ 2,122,891 North American Secure Shredding(1) 158,020 North American Data Management(2) 505,690 Adjacent Businesses - Data Centers(3) — Adjacent Businesses - Consumer Storage(3) 3,011 Adjacent Businesses - Fine Arts(3) 22,911 Western Europe(4)(5) 349,421 Northern and Eastern Europe(6) 136,431 Latin America(6) 147,782 Australia and New Zealand(6) 274,981 Southeast Asia(5)(6) 162,351 Africa and India(6) 21,532 Total $ 3,905,021 _______________________________________________________________________________ (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) Included in this reporting unit at December 31, 2016 is the goodwill associated with our December 2016 acquisition of certain of the information management operations of Santa Fe Group A/S ("Santa Fe"), as more fully disclosed in Note 6. Our Western Europe reporting unit includes the goodwill associated with Santa Fe's information management operations in Spain, while our Southeast Asia reporting unit includes the goodwill associated with Santa Fe's information management operations in Hong Kong, Malaysia, Singapore and Taiwan. (6) This reporting unit is included in the Other International Business segment. Reporting unit valuations have been determined using a combined approach based on the present value of future cash flows and market multiples of revenues and earnings. The income approach incorporates many assumptions including future growth rates and operating margins, discount rate factors, expected capital expenditures and income tax cash flows. Changes in economic and operating conditions impacting these assumptions could result in goodwill impairments in future periods. In conjunction with our annual goodwill impairment reviews, we reconcile the sum of the valuations of all of our reporting units to our market capitalization as of such dates. The changes in the carrying value of goodwill attributable to each reportable operating segment for the years ended December 31, 2015 and 2016 is 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 $ 405,570 $ 261,458 $ — $ 2,742,219 Deductible goodwill acquired during the year 29 7 — — 26,186 26,222 Non-deductible goodwill acquired during the year 2,730 567 1,936 9,064 — 14,297 Fair value and other adjustments(1) 104 (25 ) (448 ) (353 ) — (722 ) Currency effects (27,647 ) (6,925 ) (25,909 ) (44,543 ) — (105,024 ) Gross Balance as of December 31, 2015 1,620,425 423,606 381,149 225,626 26,186 2,676,992 Deductible goodwill acquired during the year — — — — — — Non-deductible goodwill acquired during the year 867,756 135,836 73,760 578,596 215 1,656,163 Goodwill allocated to Iron Mountain Divestments(2) (3,332 ) — — (40,089 ) — (43,421 ) Fair value and other adjustments(3) (157 ) — — (971 ) (479 ) (1,607 ) Currency effects 1,114 1 (49,338 ) (20,036 ) — (68,259 ) Gross Balance as of December 31, 2016 $ 2,485,806 $ 559,443 $ 405,571 $ 743,126 $ 25,922 $ 4,219,868 Accumulated Amortization Balance as of December 31, 2014 $ 205,987 $ 54,025 $ 58,273 $ 151 $ — $ 318,436 Currency effects (1,306 ) (326 ) (768 ) (22 ) — (2,422 ) Accumulated Amortization Balance as of December 31, 2015 204,681 53,699 57,505 129 — 316,014 Currency effects 214 54 (1,355 ) (80 ) — (1,167 ) Accumulated Amortization Balance as of December 31, 2016 $ 204,895 $ 53,753 $ 56,150 $ 49 $ — $ 314,847 Net Balance as of December 31, 2015 $ 1,415,744 $ 369,907 $ 323,644 $ 225,497 $ 26,186 $ 2,360,978 Net Balance as of December 31, 2016 $ 2,280,911 $ 505,690 $ 349,421 $ 743,077 $ 25,922 $ 3,905,021 Accumulated Goodwill Impairment Balance as of December 31, 2015 $ 85,909 $ — $ 46,500 $ — $ — $ 132,409 Accumulated Goodwill Impairment Balance as of December 31, 2016 $ 85,909 $ — $ 46,500 $ — $ — $ 132,409 ___________________________________________________________________ (1) Total fair value and other adjustments primarily include $622 in net adjustments to deferred income taxes and $(5,036) related to customer relationships and acquisition costs and other assumed liabilities (which represent adjustments within the applicable measurement period to provisional amounts recognized in purchase accounting), as well as $3,692 of cash paid related to certain acquisitions completed in 2014. (2) Goodwill allocated to Iron Mountain Divestments includes $40,089 and $3,332 of goodwill allocated to the Australia Divestment Business and the Iron Mountain Canadian Divestments (each as defined in Note 6), respectively. (3) Total fair value and other adjustments primarily include net adjustments of $( 1,425 ) related to property, plant and equipment, customer relationship intangible assets (which represent adjustments within the applicable measurement period to provisional amounts recognized in purchase accounting) and other liabilities, and $182 of cash received related to certain acquisitions completed in 2015. i. Customer Relationship Intangible Assets, Customer Inducements and Other Finite-Lived Intangible Assets Customer relationship intangible assets, which are acquired through either business combinations or acquisitions of customer relationships, are amortized over periods ranging from eight to 30 years (weighted average of 18 years at December 31, 2016 ). The value of customer relationship intangible assets is calculated based upon estimates of their fair value utilizing an income approach based on the present value of expected future cash flows. Costs related to the acquisition of large volume accounts are capitalized. Free intake costs to transport boxes to one of our facilities, which include labor and transportation costs ("Move Costs"), are amortized over periods ranging from eight to 30 years (weighted average of 26 years at December 31, 2016 ), and are included in depreciation and amortization in the accompanying Consolidated Statements of Operations. Payments that are made to a customer's current records management vendor in order to terminate the customer's existing contract with that vendor, or direct payments to a customer ("Permanent Withdrawal Fees"), are amortized over periods ranging from three to 15 years (weighted average of eight years at December 31, 2016 ), and are included in storage and service revenue in the accompanying Consolidated Statements of Operations. Move Costs and Permanent Withdrawal Fees are collectively referred to as "Customer Inducements". If the customer terminates its relationship with us, the unamortized carrying value of the Customer Inducement intangible asset is charged to expense or revenue. However, in the event of such termination, we generally collect, and record as income, permanent removal fees that generally equal or exceed the amount of the unamortized Customer Inducement intangible asset. Other finite-lived intangible assets, including trade names, noncompetition agreements and trademarks, are capitalized and amortized over periods ranging from three to 10 years (weighted average of eight years at December 31, 2016 ). The gross carrying amount and accumulated amortization of our finite-lived intangible assets as of December 31, 2015 and 2016, respectively, are as follows: December 31, Gross Carrying Amount 2015 2016 Customer relationship intangible assets and Customer Inducements $ 937,174 $ 1,604,020 Other finite-lived intangible assets (included in other assets, net) 11,111 24,788 Accumulated Amortization Customer relationship intangible assets and Customer Inducements $ 333,860 $ 351,497 Other finite-lived intangible assets (included in other assets, net) 8,325 7,989 Amortization expense associated with finite-lived intangible assets for the years ended December 31, 2014 , 2015 and 2016 is as follows: Year Ended December 31, 2014 2015 2016 Customer relationship intangible assets and Customer Inducements: Amortization expense included in depreciation and amortization $ 46,733 $ 43,614 $ 84,349 Revenue reduction associated with amortization of Permanent Withdrawal Fees 11,715 11,670 12,217 Other finite-lived intangible assets: Amortization expense included in depreciation and amortization 1,853 631 2,451 Estimated amortization expense for existing finite-lived intangible assets (excluding deferred financing costs, as disclosed in Note 2.j.) is as follows: Estimated Amortization Included in Depreciation Charged to Revenues 2017 $ 93,956 $ 7,907 2018 93,040 6,520 2019 91,389 4,776 2020 90,970 3,501 2021 90,283 2,424 j. Deferred Financing Costs Deferred financing costs are amortized over the life of the related debt using the effective interest rate method. If debt is retired early, the related unamortized deferred financing costs are written off in the period the debt is retired to other expense (income), net. As of December 31, 2015 and 2016, gross carrying amount of deferred financing costs was $70,549 and $92,982 , respectively, and accumulated amortization of those costs was $12,250 and $25,047 , respectively.

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 both the Former Revolving Credit Facility and the Revolving Credit Facility (each of which is defined below). The fair value (Level 3 of fair value hierarchy described at Note 2.s.) 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 December 31, 2015 and 2016, respectively. (2) The fair values (Level 1 of fair value hierarchy described at Note 2.s.) of these debt instruments are based on quoted market prices for these notes on December 31, 2015 and 2016 , 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 its direct and indirect 100% owned United States subsidiaries that represent the substantial majority of our United States operations (the "Guarantors"). These guarantees are joint and several obligations of the Guarantors. Canada Company, Iron Mountain Europe PLC ("IME"), the Accounts Receivable Securitization Special Purpose Subsidiaries (as defined below), the Mortgage Securitization Special Purpose Subsidiary (as defined below) and the remainder of our subsidiaries do not guarantee the Parent Notes. See Note 5. (4) The 6% Notes due 2020, the 4 3 / 8 % Notes, the GBP Notes, the CAD Notes due 2023 and the 5 3 / 8 % Notes (collectively, the "Unregistered Notes") have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or under the securities laws of any other jurisdiction. Unless they are registered, the Unregistered Notes may be offered only in transactions that are exempt from registration under the Securities Act or the securities laws of any other jurisdiction.

(6) 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 5. (7) Includes (i) real estate mortgages of $2,713 and $20,884 as of December 31, 2015 and 2016 , respectively, which bear interest at approximately 4.9% as of December 31, 2015 and 4.4% as of December 31, 2016 and are payable in various installments through 2021, (ii) capital lease obligations of $235,348 and $309,860 as of December 31, 2015 and 2016 , respectively, which bear a weighted average interest rate of 7.2% at December 31, 2015 and 4.6% at December 31, 2016 , and (iii) other notes and other obligations, which were assumed by us as a result of certain acquisitions, of $95,498 and $147,821 as of December 31, 2015 and 2016 , respectively, and bear a weighted average interest rate of 12.6% as of both December 31, 2015 and 2016 , respectively. We believe the fair value (Level 3 of fair value hierarchy described at Note 2.s.) of this debt approximates its carrying value. (8) The Accounts Receivable Securitization Special Purpose Subsidiaries are the obligors under this program. We believe the fair value (Level 3 of fair value hierarchy described at Note 2.s.) of this debt approximates its carrying value. (9) The fair value (Level 3 of fair value hierarchy described at Note 2.s.) of this debt instrument approximates the carrying value as borrowings under this debt instrument are based on a current variable market interest rate. The amount of debt for the AUD Term Loan reflects an unamortized original issue discount of $1,725 as of December 31, 2016. (10) Iron Mountain US Holdings, Inc. ("IM US Holdings"), a 100% owned subsidiary of IMI and one of the Guarantors, is the direct obligor on the 5 3 / 8 % Notes, which are fully and unconditionally guaranteed, on a senior basis, by IMI and the other Guarantors. These guarantees are joint and several obligations of IMI and such Guarantors. See Note 5. (11) The Mortgage Securitization Special Purpose Subsidiary is the obligor under this program. We believe the fair value (Level 3 of fair value hierarchy described at Note 2.s.) of this debt approximates its carrying value. a. Credit Agreement On July 2, 2015, we entered into a new credit agreement (the "Credit Agreement") to refinance our then existing credit agreement (the "Former Credit Agreement") which consisted of a revolving credit facility (the "Former Revolving Credit Facility") and a term loan and was scheduled to terminate on June 27, 2016. The Credit Agreement consists of a revolving credit facility (the "Revolving Credit Facility") and a term loan (the "Term Loan"). The initial maximum amount of the Revolving Credit Facility was $1,500,000 . The original amount of the Term Loan was $250,000 . We recorded a charge of $2,156 to other expense (income), net in the third quarter of 2015 related to the refinancing of the Former Credit Agreement, representing a write-off of unamortized deferred financing costs. On June 24, 2016, Iron Mountain Information Management, LLC (“IMIM”) entered into a commitment increase supplement, pursuant to which we increased the maximum amount permitted to be borrowed under the Revolving Credit Facility from $1,500,000 to $1,750,000 . We continue to have the option to request additional term loans and/or increases in commitments under the Revolving Credit Facility up to $250,000 , subject to the conditions specified in the Credit Agreement. The Revolving Credit Facility is supported by a group of 25 banks and 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 $1,750,000 . The Term Loan is to be paid in quarterly installments in an amount equal to $3,125 per quarter, with the remaining balance due on July 3, 2019. The 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 Credit Agreement. Borrowings under the Credit Agreement may be prepaid without penalty or premium, in whole or in part, at any time. IMI and the Guarantors guarantee all obligations under the Credit Agreement. The interest rate on borrowings under the Credit Agreement varies depending on our choice of interest rate and currency options, plus an applicable margin, which varies based on our consolidated leverage ratio. Additionally, the Credit Agreement requires the payment of a commitment fee on the unused portion of the Revolving Credit Facility, which fee ranges from between 0.25% to 0.4% based on our consolidated leverage ratio and fees associated with outstanding letters of credit. As of December 31, 2016, we had $953,548 and $234,375 of outstanding borrowings under the Revolving Credit Facility and the Term Loan, respectively. Of the $953,548 of outstanding borrowings under the Revolving Credit Facility, $787,400 was denominated in United States dollars and 157,930 was denominated in Euros. In addition, we also had various outstanding letters of credit totaling $54,957 . The remaining amount available for borrowing under the Revolving Credit Facility as of December 31, 2016, 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 $741,495 (which amount represents the maximum availability as of such date). The average interest rate in effect under the Credit Agreement was 2.9% as of December 31, 2016. The average interest rate in effect under the Revolving Credit Facility was 2.9% and ranged from 2.3% to 5.0% as of December 31, 2016 and the interest rate in effect under the Term Loan as of December 31, 2016 was 2.8% . 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, 2015 and 2016 and our leverage ratio under our indentures as of December 31, 2015 and 2016 are as follows: December 31, 2015 December 31, 2016 Maximum/Minimum Allowable Net total lease adjusted leverage ratio 5.6 5.7 Maximum allowable of 6.5 Net secured debt lease adjusted leverage ratio 2.6 2.7 Maximum allowable of 4.0 Bond leverage ratio (not lease adjusted) 5.5 5.2 Maximum allowable of 6.5 Fixed charge coverage ratio 2.4 2.4 Minimum allowable of 1.5 As noted in the table above, our maximum allowable net total lease adjusted leverage ratio under the Credit Agreement is 6.5 . The Credit Agreement also contains a provision which limits, in certain circumstances, our dividends in any four consecutive fiscal quarters to 95% of Funds From Operations (as defined in the Credit Agreement) for such four fiscal quarters or, if greater, the amount that we would be required to pay in order to continue to be qualified for taxation as a REIT or to avoid the imposition of income or excise taxes on IMI. This limitation only is applicable when our net total lease adjusted leverage ratio exceeds 6.0 as measured as of the end of the most recently completed fiscal quarter. 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 Former Revolving Credit Facility, the Revolving Credit Facility and the Accounts Receivable Securitization Program (as defined below) for the years ended December 31, 2014 , 2015 and 2016 , are as follows: Year Ended December 31, 2014 2015 2016 Commitment fees and letters of credit fees $ 3,322 $ 3,743 $ 3,533 b. Bridge Facility On April 29, 2016, in order to provide a portion of the financing necessary to close the Recall Transaction, we entered into a bridge credit agreement (the “Bridge Credit Agreement”) with JPMorgan Chase Bank, N.A., as a lender and administrative agent, and the other lenders party thereto (the "Lenders"), pursuant to which we borrowed an unsecured bridge term loan of $850,000 (the "Bridge Facility"). We used the proceeds from the Bridge Facility, together with borrowings under the Revolving Credit Facility, to finance a portion of the cost of the Recall Transaction, including refinancing Recall’s existing indebtedness and to pay costs we incurred in connection with the Recall Transaction. On May 31, 2016, we used the proceeds from the issuance of the 4⅜% Notes and the 5⅜% Notes, together with cash on hand and borrowings under the Revolving Credit Facility, to repay the Bridge Facility, and effective May 31, 2016, we terminated the commitments of the Lenders under the Bridge Credit Agreement. We recorded a charge to other expense (income), net of $9,283 during the second quarter of 2016 related to the early extinguishment of the Bridge Credit Agreement. This charge primarily consisted of the write-off of unamortized deferred financing costs. c. Notes Issued under Indentures As of December 31, 2016 , we had eight series of senior subordinated or senior notes issued under various indentures, four of which are direct obligations of the parent company, IMI; one of which (the 5 3 / 8 % Notes) is a direct obligation of IM US Holdings; two of which (the CAD Notes) are a direct obligation of Canada Company; and one of which (the GBP Notes) is a direct obligation of IME. All notes shown below are pari passu with debt outstanding under the Credit Agreement, except the 5 3 / 4 % Notes which are subordinated to the Credit Agreement: • $1,000,000 principal amount of senior notes maturing on October 1, 2020 and bearing interest at a rate of 6% per annum, payable semi-annually in arrears on April 1 and October 1; • $500,000 principal amount of senior notes maturing on June 1, 2021 and bearing interest at a rate of 4 3 / 8 % per annum, payable semi-annually in arrears on December 1 and June 1; • 200,000 CAD principal amount of senior notes maturing on August 15, 2021 and bearing interest at a rate of 6 1 / 8 % per annum, payable semi-annually in arrears on February 15 and August 15; • 400,000 British pounds sterling principal amount of senior notes maturing on September 15, 2022 and bearing interest at a rate of 6 1 / 8 % per annum, payable semi-annually in arrears on March 15 and September 15; • $600,000 principal amount of senior notes maturing on August 15, 2023 and bearing interest at a rate of 6% per annum, payable semi-annually in arrears on February 15 and August 15; • 250,000 CAD principal amount of senior notes maturing on September 15, 2023 and bearing interest at a rate of 5 3 / 8 % per annum, payable semi-annually in arrears on March 15 and September 15; • $1,000,000 principal amount of senior subordinated notes maturing on August 15, 2024 and bearing interest at a rate of 5 3 / 4 % per annum, payable semi-annually in arrears on February 15 and August 15; and • $250,000 principal amount of senior notes maturing on June 1, 2026 and bearing interest at a rate of 5 3 / 8 % per annum, payable semi-annually in arrears on December 1 and June 1. In January 2014, we redeemed the 150,000 British pounds sterling (approximately $248,000 ) in aggregate principal amount of our 7 1 / 4 % Notes at 100% of par, plus accrued and unpaid interest, utilizing borrowings under the Former Revolving Credit Facility and cash on-hand. In September 2014, IME completed a private offering of 400,000 British pounds sterling in aggregate principal amount of the GBP Notes, which were issued at 100% of par. The net proceeds to IME of 394,000 British pounds sterling (approximately $642,000 based on an exchange rate of 1.63 ), after paying the initial purchasers' commissions and expenses, were used to repay amounts outstanding under the Former Revolving Credit Facility and for general corporate purposes. In December 2014, we redeemed $306,000 aggregate principal outstanding of our previously outstanding 8 3 / 8 % Senior Subordinated Notes due 2021 (the "8 3 / 8 % Notes") at 104.188% of par, plus accrued and unpaid interest, utilizing borrowings under the Former Revolving Credit Facility. We recorded a charge to other expense (income), net of $16,495 related to the early extinguishment of this debt in the fourth quarter of 2014 representing the call premium associated with the early redemption, as well as a write-off of original issue discounts and unamortized deferred financing costs. In September 2015, IMI completed a private offering of $1,000,000 in aggregate principal amount of the 6% Notes due 2020. The net proceeds to IMI of $985,000 , after paying the initial purchasers’ commissions and expenses, were used to redeem all of the 6 3 / 4 % Notes and the 7 3 / 4 % Senior Subordinated Notes due 2019, as well as the remainder of the 8 3 / 8 % Notes in October 2015. The remaining net proceeds were used for general corporate purposes, including acquisitions. We recorded a charge to other expense (income), net of $25,112 in the fourth quarter of 2015 related to the early extinguishment of this debt. This charge consists of call premiums, original issue discounts and unamortized deferred financing costs. In May 2016, IMI completed a private offering of $500,000 in aggregate principal amount of the 4 3 / 8 % Notes and IM US Holdings completed a private offering of $250,000 in aggregate principal amount of the 5 3 / 8 % Notes. The 4 3 / 8 % Notes and 5 3 / 8 % Notes were issued at par. The aggregate net proceeds of $738,750 from the 4 3 / 8 % Notes and 5 3 / 8 % Notes, after paying the initial purchasers' commissions, were used, together with cash on hand and borrowings under the Revolving Credit Facility, for the repayment of all outstanding borrowings under the Bridge Credit Agreement. On September 15, 2016, Canada Company completed a private offering of 250,000 Canadian dollars in aggregate principal amount of the CAD Notes due 2023. The CAD Notes due 2023 were issued at par. The aggregate net proceeds from the CAD Notes due 2023 of 246,250 Canadian dollars (or $186,693 , based upon the exchange rate between the Canadian dollar and the United States dollar on September 15, 2016 (the settlement date for the CAD Notes due 2023)), after paying the initial purchasers’ commissions, were used to repay outstanding borrowings under the Revolving Credit Facility. Each of the indentures for the notes provides that we may redeem the outstanding notes, in whole or in part, upon satisfaction of certain terms and conditions. In any redemption, we are also required to pay all accrued but unpaid interest on the outstanding notes. The following table presents the various redemption dates and prices of the senior or senior subordinated notes. The redemption dates reflect the date at or after which the notes may be redeemed at our option at a premium redemption price. After these dates, the notes may be redeemed at 100% of face value: Redemption Date 6% Notes due 2020 October 1, 4 3 / 8 % Notes June 1, CAD Notes due 2021 August 15, GBP Notes September 15, 6% Notes due 2023 August 15, CAD Notes due 2023 5 3 / 4 % Notes August 15, 5 3 / 8 % Notes June 1, 2017 103.000 % (1) — 103.063 % (1) 104.594 % (1) — — 102.875 % (1) — 2018 101.500 % 102.188 % (1) 101.531 % 103.063 % 103.000 % (1) — 101.917 % — 2019 100.000 % 101.094 % 100.000 % 101.531 % 102.000 % 104.031 % (1) 100.958 % — 2020 100.000 % 100.000 % 100.000 % 100.000 % 101.000 % 102.688 % 100.000 % — 2021 — 100.000 % 100.000 % 100.000 % 100.000 % 101.344 % 100.000 % 102.688 % (1) 2022 — — — 100.000 % 100.000 % 100.000 % 100.000 % 101.792 % 2023 — — — — 100.000 % 100.000 % 100.000 % 100.896 % 2024 — — — — — — 100.000 % 100.000 % 2025 — — — — — — — 100.000 % 2026 — — — — — — — 100.000 % _______________________________________________________________________________ (1) Prior to this date, the relevant notes are redeemable, at our option, in whole or in part, at a specified make-whole price. Each of the indentures for the notes provides that we must repurchase, at the option of the holders, the notes at 101% of their principal amount, plus accrued and unpaid interest, upon the occurrence of a "Change of Control," which is defined in each respective indenture. Except for required repurchases upon the occurrence of a Change of Control or in the event of certain asset sales, each as described in the respective indenture, we are not required to make sinking fund or redemption payments with respect to any of the notes. d. Australian Dollar Term Loan On September 28, 2016, Iron Mountain Australia Group Pty, Ltd., a wholly owned subsidiary of IMI, entered into a 250,000 Australian dollar Syndicated Term Loan B Facility, the AUD Term Loan, which matures in September 2022. The AUD Term Loan was issued at 99% of par. The net proceeds of approximately 243,750 Australian dollars (or approximately $185,800 , based upon the exchange rate between the Australian dollar and the United States dollar on September 28, 2016 (the settlement date for the AUD Term Loan)), after paying commissions to the joint lead arrangers and net of the original discount, were used to repay outstanding borrowings under the Revolving Credit Facility and for general corporate purposes. Principal payments on the AUD Term Loan are to be paid in quarterly installments in an amount equivalent to an aggregate of 6,250 Australian dollars per year, with the remaining balance due on September 28, 2022. The AUD Term Loan is secured by substantially all assets of Iron Mountain Australia Group Pty. Ltd. IMI and the Guarantors guarantee all obligations under the AUD Term Loan. The interest rate on borrowings under the AUD Term Loan is based upon BBSY (an Australian benchmark variable interest rate) plus 4.3% . As of December 31, 2016, we had 248,437 Australian dollars ( $178,923 based upon the exchange rate between the United States dollar and the Australian dollar as of December 31, 2016) outstanding on the AUD Term Loan and the interest rate in effect under the AUD Term Loan was 6.1% . e. Accounts Receivable Securitization Program 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 "Accounts Receivable Securitization Special Purpose Subsidiaries"). The Accounts Receivable Securitization Special Purpose Subsidiaries use the accounts receivable balances to collateralize loans obtained from certain financial institutions. The Accounts Receivable Securitization Special Purpose Subsidiaries are consolidated subsidiaries of IMI. The Accounts Receivable Securitization Program is accounted for as a collateralized financing activity, rather than a sale of assets, and therefore: (i) accounts receivable balances pledged as collateral are presented as assets and borrowings are presented as liabilities on our Consolidated Balance Sheets, (ii) our Consolidated Statements of Operations reflect the associated charges for bad debt expense related to pledged accounts receivable (a component of selling, general and administrative expenses) and reductions to revenue due to billing and service related credit memos issued to customers and related reserves, as well as interest expense associated with the collateralized borrowings and (iii) receipts from customers related to the underlying accounts receivable are reflected as operating cash flows and borrowings and repayments under the collateralized loans are reflected as financing cash flows within our Consolidated Statements of Cash Flows. IMIM retains the responsibility of servicing the accounts receivable balances pledged as collateral 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 December 31, 2015 and 2016, the maximum availability allowed and amount outstanding under the Accounts Receivable Securitization Program was $205,900 and $247,000 , respectively. The interest rate in effect under the Accounts Receivable Securitization Program was 1.3% and 1.7% as of December 31, 2015 and 2016, respectively. Commitment fees at a rate of 40 basis points are charged on amounts made available but not borrowed under the Accounts Receivable Securitization Program. f. Mortgage Securitization Program In October 2016, we entered into a $50,000 mortgage securitization program (the "Mortgage Securitization Program") involving certain of our wholly owned subsidiaries with Goldman Sachs Mortgage Company (“Goldman Sachs”). Under the Mortgage Securitization Program, IMIM contributed certain real estate assets to its wholly owned special purpose entity, Iron Mountain Mortgage Finance I, LLC (the "Mortgage Securitization Special Purpose Subsidiary"). The Mortgage Securitization Special Purpose Subsidiary then used the real estate to secure a collateralized loan obtained from Goldman Sachs. The Mortgage Securitization Special Purpose Subsidiary is a consolidated subsidiary of IMI. The Mortgage Securitization Program is accounted for as a collateralized financing activity, rather than a sale of assets, and therefore: (i) real estate assets pledged as collateral remain as assets and borrowings are presented as liabilities on our Consolidated Balance Sheet, (ii) our Consolidated Statement of Operations reflects the associated charges for depreciation expense related to the pledged real estate and interest expense associated with the collateralized borrowings and (iii) borrowings and repayments under the collateralized loans are reflected as financing cash flows within our Consolidated Statement of Cash Flows. The Mortgage Securitization Program is scheduled to terminate on November 6, 2026, at which point all obligations become due. As of December 31, 2016, the outstanding amount under the Mortgage Securitization Program was $50,000 . The interest rate in effect under the Mortgage Securitization Program was 3.5% as of December 31, 2016. g. Cash Pooling Subsequent to the closing of the Recall Transaction, certain of our international subsidiaries began participating in a cash pooling arrangement (the “Cash Pool”) with Bank Mendes Gans (“BMG”) in order to help manage global liquidity requirements. The Cash Pool allows participating subsidiaries to receive credit for cash balances deposited by participating subsidiaries in BMG accounts. Under the Cash Pool, cash deposited by participating subsidiaries with BMG is pledged as security against the drawings of other participating subsidiaries, and legal rights of offset are provided and, therefore, amounts are presented in our Consolidated Balance Sheet on a net basis. Each subsidiary receives interest on the cash balances held on deposit or pays interest on the amounts owed based on an applicable rate as defined in the Cash Pool agreement. At December 31, 2016, we had a net cash position of approximately $1,700 (consisting of a gross cash position of approximately $69,500 less outstanding borrowings of approximately $67,800 by participating subsidiaries), which is reflected as cash and cash equivalents in the Consolidated Balance Sheet. _______________________________________________________________________________ Maturities of long-term debt are as follows: Year Amount 2017 $ 172,975 2018 338,540 2019 1,218,880 2020 1,071,088 2021 678,713 Thereafter 2,840,645 6,320,841 Net Discounts (1,725 ) Net Deferred Financing Costs (67,935 ) Total Long-term Debt (including current portion) $ 6,251,181

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, 2015 and 2016 and for the years ended December 31, 2014 , 2015 and 2016 and are prepared on the same basis as the consolidated financial statements. The Parent Notes, CAD Notes, GBP Notes and the 5 3 / 8 % Notes are guaranteed by the subsidiaries referred to below as the Guarantors. These subsidiaries are 100% owned by IMI. The guarantees are full and unconditional, as well as joint and several. Additionally, IMI guarantees the CAD Notes, which were issued by Canada Company, the GBP Notes, which were issued by IME, and the 5 3 / 8 % Notes, which were issued by IM US Holdings. Canada Company and IME do not guarantee the Parent Notes. The subsidiaries that do not guarantee the Parent Notes, the CAD Notes, the GBP Notes, and the 5 3 / 8 % Notes, including IME, the Accounts Receivable Securitization Special Purpose Subsidiaries and the Mortgage Securitization Special Purpose Subsidiary, 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 and Comprehensive Income (Loss) with respect to the relevant Parent, Guarantors, Canada Company, Non-Guarantors and Eliminations columns also would change. In July 2016, certain Non-Guarantor subsidiaries which were originally established at the time of our acquisition of Crozier in December 2015 (the “Crozier Entities”), were merged into IMIM, a Guarantor and a substantive operating entity (the “Crozier Merger”). As a result of the Crozier Merger, we have recast the accompanying Consolidated Balance Sheet as of December 31, 2015, Consolidated Statements of Operations and Comprehensive Income (Loss) for the year ended December 31, 2015, and the accompanying Consolidated Statement of Cash Flows for the year ended December 31, 2015 to conform to the current period presentation of the Crozier Entities. Therefore, (i) the assets, liabilities and equity of the Crozier Entities are now reported in the Guarantor column of the accompanying Consolidated Balance Sheets as of December 31, 2015 and 2016, respectively; (ii) the revenues and expenses of the Crozier Entities are now reported in the Guarantor column in the accompanying Consolidated Statements of Operations and Comprehensive Income (Loss) for the years ended December 31, 2015 and 2016, respectively; and (iii) the cash flows of the Crozier Entities are now reported in the Guarantor column in the accompanying Consolidated Statements of Cash Flows for the years ended December 31, 2015 and 2016, respectively. As noted in Note 4, in October 2016 we entered into the Mortgage Securitization Program. Under the Mortgage Securitization Program, IMIM, a Guarantor, contributed certain real estate assets to the Mortgage Securitization Special Purpose Subsidiary, a Non-Guarantor (recorded at historical cost). Following the contribution of such real estate assets, IMIM entered into a lease agreement with the Mortgage Securitization Special Purpose Subsidiary for the right to use the real estate under which IMIM pays the Mortgage Securitization Special Purpose Subsidiary rent on a monthly basis. Intercompany rental revenues and expenses associated with the Mortgage Securitization Program are reflected as a component of Intercompany revenues in the Non-Guarantor column and as a component of Intercompany cost of sales in the Guarantor column of the accompanying Consolidated Statement of Operations and Comprehensive Income (Loss) and are eliminated in consolidation.

Business Combinations [Abstract]
Acquisitions	We account for acquisitions using the acquisition method of accounting, and, accordingly, the assets and liabilities acquired are recorded at their estimated fair values and the results of operations for each acquisition have been included in our consolidated results from their respective acquisition dates. Cash consideration for our various acquisitions in 2016 was primarily provided through cash flows from operating activities and borrowings, as well as cash and cash equivalents on hand. a. Acquisition of Recall On May 2, 2016 (Sydney, Australia time), we completed the Recall Transaction. At the closing of the Recall Transaction, we paid approximately $331,800 in cash and issued 50,233,412 shares of our common stock which, based on the closing price of our common stock as of April 29, 2016 (the last day of trading on the NYSE prior to the closing of the Recall Transaction) of $ 36.53 per share, resulted in a total purchase price to Recall shareholders of approximately $2,166,900 . Regulatory Approvals In connection with the acquisition of Recall, we sought regulatory approval of the Recall Transaction from the United States Department of Justice (the “DOJ”), the Australian Competition, Consumer Commission (the “ACCC”), the Canada Competition Bureau (the “CCB”) and the United Kingdom Competition and Markets Authority (the “CMA”). As part of the regulatory approval process, we agreed to make certain divestments, which are described below in greater detail, in order to address competition concerns raised by the DOJ, the ACCC, the CCB and the CMA in respect of the Recall Transaction (the “Divestments”). See Note 14 for additional information regarding the presentation of the Divestments in our Consolidated Statements of Operations and our Consolidated Statements of Cash Flows for the years ended December 31, 2014, 2015 and 2016, respectively. Divestments i. United States The DOJ’s approval of the Recall Transaction was subject to the following divestments being made by us following the closing of the Recall Transaction: • Recall’s records and information management facilities, including all associated tangible and intangible assets, in the following 13 United States cities: Buffalo, New York; Charlotte, North Carolina; Detroit, Michigan; Durham, North Carolina; Greenville/Spartanburg, South Carolina; Kansas City, Kansas/Missouri; Nashville, Tennessee; Pittsburgh, Pennsylvania; Raleigh, North Carolina; Richmond, Virginia; San Antonio, Texas; Tulsa, Oklahoma; and San Diego, California (the “Initial United States Divestments”); and • Recall’s records and information management facility in Seattle, Washington and certain of Recall’s records and information management facilities in Atlanta, Georgia, including in each case associated tangible and intangible assets (the “Seattle/Atlanta Divestments”). On May 4, 2016, we completed the sale of the Initial United States Divestments to Access CIG, LLC, a privately held provider of information management services throughout the United States (“Access CIG”), for total consideration of approximately $80,000 , subject to adjustments (the “Access Sale”). Of the total consideration, we received $55,000 in cash proceeds upon closing of the Access Sale, and we are entitled to receive up to $25,000 of additional cash proceeds on the 27-month anniversary of the closing of the Access Sale (the "Access Contingent Consideration"). Our estimate of the fair value of the Access Contingent Consideration is approximately $21,400 (which reflects a fair value adjustment of approximately $2,200 and a present value adjustment of approximately $1,400 ). We have a non-trade receivable amounting to $21,800 included in Other, a component of Other Assets, Net in our Consolidated Balance Sheet as of December 31, 2016 related to the Access Contingent Consideration. The assets subject to the Access Sale were acquired in the Recall Transaction and, therefore, the estimated fair value of the Initial United States Divestments (including the estimated fair value of the Access Contingent Consideration) has been reflected in the allocation of the purchase price for Recall as a component of “Fair Value of Recall Divestments”. Our policy related to the recognition of contingent consideration (from a seller’s perspective) is to recognize contingent consideration at its estimated fair value upon closing of the transaction. Our policy related to the subsequent measurement of contingent consideration (from a seller’s perspective) is (i) to recognize contingent consideration in excess of our original estimate of fair value upon cash receipt of such consideration and (ii) to recognize any impairment of the contingent consideration compared to our original estimate in the period in which we determine such an impairment exists. On December 29, 2016, we completed the sale of the Seattle/Atlanta Divestments and the Canadian Divestments (as defined below) to ARKIVE, Inc., an information management company (“ARKIVE”), for total consideration of approximately $50,000 , subject to adjustments (the “ARKIVE Sale”). Of the total consideration, we received approximately $45,000 in cash proceeds upon the closing of the ARKIVE Sale and the remaining consideration is held in escrow. ARKIVE may be entitled to receive from us, on the 24-month anniversary of the closing of the ARKIVE Sale, cash payments, up to the total consideration paid by ARKIVE, based on lost revenues attributable to the acquired customer base. The assets included in the Seattle/Atlanta Divestments and the Recall Canadian Divestments were acquired in the Recall Transaction and, therefore, the estimated fair value of the Seattle/Atlanta Divestments and the Recall Canadian Divestments (as determined based upon the total consideration for the ARKIVE Sale) has been reflected in the allocation of the purchase price for Recall as a component of "Fair Value of Recall Divestments". ii. Australia The ACCC approved the Recall Transaction after accepting an undertaking from us pursuant to section 87B of the Australian Competition and Consumer Act 2010 (Cth) (the “ACCC Undertaking”). Pursuant to the ACCC Undertaking, we agreed to divest the majority of our Australian operations as they existed prior to the closing of the Recall Transaction by way of a share sale, which effectively involved the sale of our Australian business (as it existed prior to the closing of the Recall Transaction) other than our data management business throughout Australia and our records and information management business in the Northern Territory of Australia, except in relation to customers who have holdings in other Australian states or territories (the “Australia Divestment Business” and, with respect to the portion of our Australia business that was not subject to divestment, the “Australia Retained Business”). On October 31, 2016, after receiving approval of the proposed transaction from the ACCC, we completed the sale of the Australia Divestment Business (the “Australia Sale”) to a consortium led by Housatonic Partners (the “Australia Divestment Business Purchasers”) for total consideration of approximately 70,000 Australian dollars (or approximately $53,200 , based upon the exchange rate between the United States dollar and the Australian dollar as of October 31, 2016), subject to adjustments. The total consideration consists of (i) 35,000 Australian dollars in cash received upon the closing of the Australia Sale and (ii) 35,000 Australian dollars in the form of a note due from the Australia Divestment Business Purchasers to us (the “Bridging Loan Note”). The Bridging Loan Note bears interest at 3.3% per annum and matures on December 29, 2017, at which point all outstanding obligations become due. The total consideration for the Australia Sale is subject to certain adjustments associated with customer attrition subsequent to the closing of the Australia Sale. We recorded a charge of $15,417 to other expense, net associated with the loss on disposal of the Australia Divestment Business during the year ended December 31, 2016, representing the excess of the carrying value of the Australia Divestment Business compared to its fair value (less costs to sell). Approximately $7,099 of cumulative translation adjustment associated with the Australian Divestment Business was reclassified from accumulated other comprehensive items, net and reduced the loss recorded on the sale of the Australia Divestment Business by the same amount. iii. Canada The CCB approved the Recall Transaction on the basis of us divesting the following assets: • Recall’s record and information management facilities, including associated tangible and intangible assets and employees, in Edmonton, Alberta and Montreal (Laval), Quebec and certain of Recall’s record and information management facilities, including all associated tangible and intangible assets and employees, in Calgary, Alberta and Toronto, Ontario, (the “Recall Canadian Divestments”); and • One of our records and information management facilities in Vancouver (Burnaby), British Columbia and one of our records and information management facilities in Ottawa, Ontario, including associated tangible and intangible assets and employees (the “Iron Mountain Canadian Divestments” and together with the Recall Canadian Divestments, the "Canadian Divestments"). On December 29, 2016, we completed the sale of the Canadian Divestments (along with the Seattle/Atlanta Divestments) in the ARKIVE Sale, as discussed above. We recorded a charge of $1,421 to other expense, net associated with the loss on disposal of the Iron Mountain Canadian Divestments during the year ended December 31, 2016, representing the excess of the carrying value of the Iron Mountain Canadian Divestments compared to its fair value (as determined based upon the total consideration received in the ARKIVE Sale), less costs to sell. iv. United Kingdom On June 16, 2016, the CMA published its findings, pursuant to which we agreed to divest Recall’s record and information management facilities, including associated tangible and intangible assets and employees, in the Aberdeen and Dundee areas of Scotland (the “UK Divestments”). On December 9, 2016, we completed the sale of the UK Divestments (the "UK Sale") to the Oasis Group for total consideration of approximately 1,800 British pounds sterling (or approximately $2,200 , based upon the exchange rate between the United States dollar and the British pound sterling as of December 9, 2016), subject to adjustments. The assets included in the UK Sale were acquired in the Recall Transaction and, therefore, the estimated fair value of the UK Divestments (as determined based upon the total consideration received in the UK Sale) has been reflected in the allocation of the purchase price for Recall as a component of “Fair Value of Recall Divestments”. _______________________________________________________________________________ The unaudited consolidated pro forma financial information (the "Pro Forma Financial Information") below summarizes the combined results of us and Recall on a pro forma basis as if the Recall Transaction had occurred on January 1, 2015. The Pro Forma Financial Information is presented for informational purposes and is not necessarily indicative of the results of operations that would have been achieved if the acquisition had taken place on January 1, 2015. The Pro Forma Financial Information, for all periods presented, includes adjustments to convert Recall's historical results from International Financial Reporting Standards to GAAP, our current estimates of purchase accounting adjustments (including amortization of acquired intangible assets, depreciation of acquired property, plant and equipment and amortization of favorable and unfavorable leases), stock-based compensation and related tax effects. Through December 31, 2016, we and Recall have collectively incurred $140,661 of operating expenditures to complete the Recall Transaction (including advisory and professional fees and costs to complete the Divestments and to provide transitional services required to support the divested businesses during a transition period). These operating expenditures have been reflected within the results of operations in the Pro Forma Financial Information as if they were incurred on January 1, 2015. The costs we have incurred to integrate Recall with our existing operations, including moving, severance, facility upgrade, REIT conversion and system upgrade costs are reflected in the Pro Forma Financial Information in the period in which they were incurred. The Pro Forma Financial Information, for all periods presented, excludes from income (loss) from continuing operations the results of operations of the Initial United States Divestments, the Seattle/Atlanta Divestments, the Recall Canadian Divestments and the UK Divestments, as these businesses are presented as discontinued operations. See Note 14 for information regarding our conclusion with respect to the presentation of these divestments as discontinued operations. The results of the Australia Divestment Business and the Iron Mountain Canadian Divestments are included within the results from continuing operations in the Pro Forma Financial Information through the closing date of the Australia Sale, in the case of the Australia Divestment Business, and through the closing date of the ARKIVE Sale, in the case of the Iron Mountain Canadian Divestments, as these businesses do not qualify for discontinued operations. See Note 14 for information regarding our conclusion that these divestments do not meet the criteria to be reported as discontinued operations. The Australia Divestment Business and the Iron Mountain Canadian Divestments, collectively, represent $67,696 of total revenues and $7,336 of total income from continuing operations for the year ended December 31, 2015, respectively, and $46,655 of total revenues and $2,603 of total income from continuing operations for the year ended December 31, 2016, respectively. (Unaudited) Year Ended December 31, 2015 2016 Total Revenues $ 3,752,697 $ 3,762,226 Income (Loss) from Continuing Operations $ 12,416 $ 148,422 Per Share Income (Loss) from Continuing Operations - Basic $ 0.05 $ 0.57 Per Share Income (Loss) from Continuing Operations - Diluted $ 0.05 $ 0.56 The amount of revenue and earnings in our Consolidated Statement of Operations for the year ended December 31, 2016 related to Recall is impracticable for us to determine. Subsequent to the closing of the Recall Transaction, we began integrating Recall and our existing operations in order to achieve operational synergies. As a result, the revenue generated by Recall, as well as the underlying costs of sales and selling, general and administrative expenses to support Recall's business, are now integrated with the revenue we generate, as well as the costs of sales and selling, general and administrative expenses that supported our business, prior to the acquisition of Recall. In addition to our acquisition of Recall, we completed certain other acquisitions during 2014, 2015 and 2016. The Pro Forma Financial Information does not reflect these acquisitions due to the insignificant impact of these acquisitions on our consolidated results of operations. b. Other Noteworthy Acquisitions Acquisitions Completed During the Year Ended December 31, 2014 In January 2014, in order to enhance our existing operations in Australia, we acquired the stock of Tape Management Services Pty Ltd, a storage and data management company with operations in Australia, for approximately $15,300 .

In April 2014, in order to enhance our existing operations in Poland, we acquired the stock of OSG Polska sp. z.o.o., a storage rental and records management business with operations in Poland, for approximately $13,700 . In October 2014, in order to enhance our existing operations in Brazil, we acquired the stock of Keepers Brasil Ltda, a storage rental and data management business with operations in Sao Paulo, Brazil, for approximately $46,200 .

Acquisitions Completed During the Year Ended December 31, 2015 In December 2015, in order to expand our offerings in our Adjacent Businesses operating segment, we acquired Crozier, a storage, logistics and transportation business for high value paintings, photographs and other types of art belonging to individual collectors, galleries and art museums for approximately $74,200 . In December 2015, in order to enhance our existing operations in India, we acquired the stock of Navbharat Archive XPress Private Limited ("NAX"), a storage and records management company with operations in India, for approximately $ 16,100 . Of the total consideration, approximately $8,900 was funded by us, while the remaining $7,200 was contributed by the noncontrolling interest shareholder of our business in India. The amount contributed by our noncontrolling interest shareholder is presented as source of cash within debt financing and equity contribution from noncontrolling interests in our Consolidated Statement of Cash Flows. In addition to the acquisitions of Crozier and NAX noted above, during 2015, in order to enhance our existing operations in Australia, Austria, Canada, Chile, Hungary, India, Serbia, the United Kingdom and the United States, we completed 12 acquisitions for total consideration of approximately $27,600 . These acquisitions included nine storage and records management companies, two storage and data management companies and one personal storage company. The individual purchase prices of these acquisitions ranged from approximately $1,000 to $5,400 . Acquisitions Completed During the Year Ended December 31, 2016 In March 2016, we acquired a controlling interest in Docufile Holdings Proprietary Limited ("Docufile"), a storage and records management company with operations in South Africa, for approximately $15,000 . The acquisition of Docufile represents our entrance into Africa. In March 2016, in order to expand our presence in the Baltic region, we acquired the stock of Archyvu Sistemos, a storage and records management company with operations in Lithuania, Latvia and Estonia, for approximately $5,100 . I n August 2016, we reached an agreement in principle under a non-binding memorandum of understanding to acquire the information management operations of Santa Fe in ten regions within Europe and Asia (the “Santa Fe Transaction”). In November 2016, we entered into a binding agreement for the Santa Fe Transaction. In December 2016, in order to expand our presence in southeast Asia and western Europe, we acquired the information management assets and operations of Santa Fe in Hong Kong, Malaysia, Singapore, Spain and Taiwan (the “2016 Santa Fe Transaction”) for approximately 15,200 Euros (approximately $16,000 , based upon the exchange rate between the United States dollar and the Euro as of December 30, 2016, the closing date of the 2016 Santa Fe Transaction). Of the total purchase price, 13,500 Euros (or approximately $14,200 , based upon the exchange rate between the United States dollar and the Euro on the closing date of the 2016 Santa Fe Transaction) was paid during the year ended December 31, 2016, and the remaining balance is due on the 18-month anniversary of the closing of the 2016 Santa Fe Transaction. _______________________________________________________________________________ A summary of the cumulative consideration paid and the allocation of the purchase price paid of all of the acquisitions in each respective year is as follows: 2016 2014 2015 Recall Other Fiscal Year 2016 Acquisitions Total Cash Paid (gross of cash acquired)(1) $ 134,301 $ 111,907 $ 331,834 $ 37,350 $ 369,184 Fair Value of Common Stock Issued — — 1,835,026 — 1,835,026 Fair Value of Noncontrolling Interests — — — 3,506 3,506 Fair Value of Previously Held Equity Interest 794 — — — — Total Consideration 135,095 111,907 2,166,860 40,856 2,207,716 Fair Value of Identifiable Assets Acquired: Cash 4,704 2,041 76,461 576 77,037 Accounts Receivable and Prepaid Expenses 10,394 10,629 176,775 2,703 179,478 Fair Value of Recall Divestments(2) — — 121,689 — 121,689 Other Assets 3,342 7,032 57,563 541 58,104 Property, Plant and Equipment(3) 23,269 43,505 622,063 10,963 633,026 Customer Relationship Intangible Assets(4) 60,172 34,988 709,139 20,842 729,981 Debt Assumed — — (792,385 ) — (792,385 ) Accounts Payable, Accrued Expenses and Other Liabilities (49,663 ) (20,729 ) (276,814 ) (11,504 ) (288,318 ) Deferred Income Taxes (1,240 ) (6,078 ) (164,074 ) (2,985 ) (167,059 ) Total Fair Value of Identifiable Net Assets Acquired 50,978 71,388 530,417 21,136 551,553 Goodwill Initially Recorded(5) $ 84,117 $ 40,519 $ 1,636,443 $ 19,720 $ 1,656,163 _______________________________________________________________________________ (1) Included in cash paid for acquisitions in the Consolidated Statement of Cash Flows for the year ended December 31, 2014 is net cash acquired of $(4,704) and contingent and other payments of $(1,504) related to acquisitions made in years prior to 2014. Included in cash paid for acquisitions in the Consolidated Statement of Cash Flows for the year ended December 31, 2015 is net cash acquired of $(2,041) and contingent and other payments of $3,692 related to acquisitions made in years prior to 2015. Included in cash paid for acquisitions in the Consolidated Statement of Cash Flows for the year ended December 31, 2016 is net cash acquired of $77,037 and cash received of $182 related to acquisitions made in years prior to 2016. (2) Represents the fair value, less costs to sell, of the Initial United States Divestments, the Seattle/Atlanta Divestments, the Recall Canadian Divestments and the UK Divestments. (3) Consists primarily of buildings, racking structures, leasehold improvements and computer hardware and software. (4) The weighted average lives of customer relationship intangible assets associated with acquisitions in 2014 , 2015 and 2016 was 17 years, 16 years and 13 years, respectively. (5) The goodwill associated with acquisitions, including Recall, is primarily attributable to the assembled workforce, expanded market opportunities and costs and other operating synergies anticipated upon the integration of the operations of us and the acquired businesses. Allocations of the purchase price for acquisitions made in 2016 were based on estimates of the fair value of the net assets acquired and are subject to adjustment upon the finalization of the purchase price allocations. The accounting for business combinations requires estimates and judgments regarding expectations for future cash flows of the acquired business, and the allocations of those cash flows to identifiable tangible and intangible assets, in determining the assets acquired and liabilities assumed. The fair values assigned to tangible and intangible assets acquired and liabilities assumed, including contingent consideration, are based on management's best estimates and assumptions, as well as other information compiled by management, including valuations that utilize customary valuation procedures and techniques. The estimates and assumptions underlying the initial valuations are subject to the collection of information necessary to complete the valuations within the measurement periods, which are up to one year from the respective acquisition dates. Assets and liabilities that were acquired and classified as held for sale immediately following the Recall Transaction were valued based on the estimated fair value of the divestment, less costs to sell. The preliminary purchase price allocations that are not finalized as of December 31, 2016 primarily relate to the final assessment of the fair values of intangible assets (primarily customer relationship intangible assets), property, plant and equipment (primarily building and racking structures), operating leases, contingencies and income taxes (primarily deferred income taxes), primarily associated with the Recall Transaction and the 2016 Santa Fe Transaction. We are not aware of any information that would indicate that the final purchase price allocations for the 2016 acquisitions will differ meaningfully from preliminary estimates. As the valuation of certain assets and liabilities for purposes of purchase price allocations are preliminary in nature, they are subject to adjustment as additional information is obtained about the facts and circumstances regarding these assets and liabilities that existed at the acquisition date. Any adjustments to our estimates of purchase price allocation will be made in the periods in which the adjustments are determined and the cumulative effect of such adjustments will be calculated as if the adjustments had been completed as of the acquisition dates. Adjustments recorded during the fourth quarter of 2016 were not material to our results from operations. _______________________________________________________________________________ In September 2014, we purchased our joint venture partners' noncontrolling interests in the businesses we operate in Russia, Ukraine and Denmark, which we had previously consolidated. The purchase price of approximately $24,500 is comprised of $17,900 paid at closing, $2,100 payable in 2017 and $4,500 payable in 2020. The components of the purchase price payable in 2017 and 2020 are reflected as non-cash items within our Consolidated Statement of Cash Flows for the year ended December 31, 2014. Of the $17,900 paid at closing, approximately $11,950 was associated with the underlying shares owned by our joint venture partners and approximately $5,950 was associated with the payment of outstanding loans between the joint venture and the joint venture partners.

Income Taxes

Income Taxes	12 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	We have been organized and operating as a REIT effective since our taxable year that began on 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 is taxed, if at all, at the stockholder level. The income of our domestic 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 TRSs. We will also be subject to a separate corporate income tax on any gains recognized during a five -year period 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 as a result of accounting method changes commenced in our pre-REIT period and in connection with the Recall Transaction. 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. The significant components of our deferred tax assets and deferred tax liabilities are presented below: December 31, 2015 2016 Deferred Tax Assets: Accrued liabilities $ 22,107 $ 30,901 Deferred rent 4,426 2,930 Net operating loss carryforwards 69,290 98,879 Federal benefit of unrecognized tax benefits 12,327 12,036 Foreign deferred tax assets and other adjustments 8,698 20,131 Valuation allowance (60,009 ) (71,359 ) 56,839 93,518 Deferred Tax Liabilities: Other assets, principally due to differences in amortization (66,254 ) (179,977 ) Plant and equipment, principally due to differences in depreciation (23,408 ) (52,572 ) (89,662 ) (232,549 ) Net deferred tax liability $ (32,823 ) $ (139,031 ) The current and noncurrent deferred tax assets and liabilities are presented below. As noted in Note 2.w., the December 31, 2016 amounts presented in the table below reflect the adoption of ASU 2015-17. December 31, 2015 2016 Deferred tax assets $ 26,668 $ — Deferred tax liabilities (4,489 ) — Current deferred tax assets, net $ 22,179 $ — Noncurrent deferred tax assets (Included in Other, a component of Other Assets, Net) $ — $ 12,264 Deferred tax assets $ 30,171 $ — Deferred tax liabilities (85,173 ) (151,295 ) Noncurrent deferred tax liabilities, net $ (55,002 ) $ (151,295 ) We have federal net operating loss carryforwards, which expire from 2023 through 2033, of $67,113 at December 31, 2016 to reduce future federal taxable income, of which $1,233 of federal tax benefit is expected to be realized. We can carry forward these net operating losses to the extent we do not utilize them in any given available year. We have state net operating loss carryforwards, which expire from 2017 through 2035, of which an insignificant state tax benefit is expected to be realized. We have assets for foreign net operating losses of $97,534 , with various expiration dates (and in some cases no expiration date), subject to a valuation allowance of approximately 73% . Rollforward of the valuation allowance is as follows: Year Ended December 31, Balance at Beginning of the Year Charged (Credited) to Expense Other Increases/(Decreases)(1) Balance at End of the Year 2014 $ 40,278 $ 9,404 $ (9,500 ) $ 40,182 2015 40,182 33,509 (13,682 ) 60,009 2016 60,009 7,660 3,690 71,359 _______________________________________________________________________________ (1) Other increases and decreases in valuation allowances are primarily related to changes in foreign currency exchange rates. We receive a tax deduction upon the exercise of non-qualified stock options or upon the disqualifying disposition by employees of incentive stock options and certain shares acquired under our ESPP for the difference between the exercise price and the market price of the underlying common stock on the date of exercise or disqualifying disposition. The tax benefit for non-qualified stock options associated with our TRSs is recorded in the consolidated financial statements in the period in which compensation expense is recorded, while the tax benefit for incentive stock options associated with our TRSs is recorded in the consolidated financial statements in the period the disqualifying disposition occurs. For the years ended December 31, 2014 and 2015, the incremental tax benefits (deficiencies) in excess of compensation expense recorded in the consolidated financial statements were (charged) credited directly to equity and amounted to $(60) and $327 , respectively. As discussed in Note 2.n., during the fourth quarter of 2016, we adopted ASU 2016-09 effective as of January 1, 2016. As a result of the adoption of ASU 2016-09, $265 of excess tax benefits are included as a component of (benefit) provision for income taxes in our Consolidated Statement of Operations for the year ended December 31, 2016. The components of income (loss) from continuing operations before (benefit) provision for income taxes and gain on sale of real estate are: Year Ended December 31, 2014 2015 2016 United States $ 202,067 $ 179,928 $ 106,223 Canada 46,191 37,131 28,157 Other Foreign (24,885 ) (54,993 ) 12,264 $ 223,373 $ 162,066 $ 146,644 The (benefit) provision for income taxes consists of the following components: Year Ended December 31, 2014 2015 2016 Federal—current $ 118,314 $ 13,083 $ 52,944 Federal—deferred (214,132 ) (9,579 ) (28,127 ) State—current 28,034 522 6,096 State—deferred (47,814 ) 158 (1,479 ) Foreign—current 27,167 31,581 36,272 Foreign—deferred (8,844 ) 1,948 (20,762 ) $ (97,275 ) $ 37,713 $ 44,944 A reconciliation of total income tax expense and the amount computed by applying the federal income tax rate of 35.0% to income from continuing operations before (benefit) provision for income taxes and gain on sale of real estate for the years ended December 31, 2014 , 2015 and 2016 , respectively, is as follows: Year Ended December 31, 2014 2015 2016 Computed "expected" tax provision $ 78,181 $ 56,723 $ 51,325 Changes in income taxes resulting from: Tax adjustment relating to REIT (63,333 ) (51,625 ) (18,526 ) Deferred tax adjustment and other taxes due to REIT conversion (182,853 ) (9,067 ) 247 State taxes (net of federal tax benefit) 2,207 2,017 3,796 Increase in valuation allowance (net operating losses) 9,404 33,509 7,660 Foreign repatriation 46,356 4,030 510 Impairment of assets and other transaction costs 2,869 — — Reserve accrual (reversal) and audit settlements (net of federal tax benefit) 3,175 (2,874 ) 1,898 Foreign tax rate differential (9,496 ) (8,915 ) (13,328 ) Disallowed foreign interest, Subpart F income, and other foreign taxes 12,502 18,022 7,773 Other, net 3,713 (4,107 ) 3,589 (Benefit) Provision for Income Taxes $ (97,275 ) $ 37,713 $ 44,944 Our effective tax rates for the years ended December 31, 2014 , 2015 and 2016 were (43.5)% , 23.3% and 30.6% , respectively. Our effective tax rate is subject to variability in the future due to, among other items: (1) changes in the mix of income between our qualified REIT subsidiaries and our TRSs, as well as among the jurisdictions in which we operate; (2) tax law changes; (3) volatility in foreign exchange gains and losses; (4) the timing of the establishment and reversal of tax reserves; and (5) our ability to utilize net operating losses that we generate. As a result of our REIT conversion, we recorded a net tax benefit of $212,151 during the year ended December 31, 2014 for the revaluation of certain deferred tax assets and liabilities associated with the REIT conversion. In 2014, we recorded an increase to the tax provision of $29,298 associated with tax accounting method changes consistent with our REIT conversion, primarily affected through the filing of amended tax returns. The other primary reconciling items between the federal statutory rate of 35.0% and our overall effective tax rate during the year ended December 31, 2014 was an increase of $46,356 in our tax provision associated with the 2014 Indefinite Reinvestment Assessment and other net tax adjustments related to the REIT conversion, including a tax benefit of $63,333 primarily related to the dividends paid deduction. The primary reconciling items between the federal statutory tax rate of 35.0% and our overall effective tax rate for the year ended December 31, 2015 were the benefit derived from the dividends paid deduction of $51,625 and an out-of-period tax adjustment ( $9,067 tax benefit) recorded during the third quarter to correct the valuation of certain deferred tax assets associated with the REIT conversion that occurred in 2014, partially offset by valuation allowances on certain of our foreign net operating losses of $33,509 , primarily related to our foreign subsidiaries in Argentina, Brazil, France and Russia. The primary reconciling items between the federal statutory tax rate of 35.0% and our overall effective tax rate for the year ended December 31, 2016 were the benefit derived from the dividends paid deduction of $18,526 and the impact of differences in the tax rates at which our foreign earnings are subject resulting in a tax benefit of $13,328 , partially offset by valuation allowances on certain of our foreign net operating losses of $7,660 . 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. The evaluation of an uncertain tax position is a two-step process. The first step is a recognition process whereby we determine whether it is more likely than not that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. The second step is a measurement process whereby a tax position that meets the more likely than not recognition threshold is calculated to determine the amount of benefit to recognize in the financial statements. The tax position is measured as the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement. We have elected to recognize interest and penalties associated with uncertain tax positions as a component of the (benefit) provision for income taxes in the accompanying Consolidated Statements of Operations. We recorded an increase of $1,462 , $2,173 and $1,805 for gross interest and penalties for the years ended December 31, 2014 , 2015 and 2016 , respectively. We had $7,120 and $8,646 accrued for the payment of interest and penalties as of December 31, 2015 and 2016 , respectively. A summary of tax years that remain subject to examination by major tax jurisdictions is as follows: Tax Years Tax Jurisdiction See Below United States—Federal and State 2007 to present Canada 2011 to present United Kingdom The normal statute of limitations for United States federal tax purposes is three years from the date the tax return is filed; however, the statute of limitations may remain open for periods longer than three years in instances where a federal tax examination is in progress. The 2012, 2013, 2014 and 2015 tax years remain subject to examination for United States federal tax purposes as well as net operating loss carryforwards utilized in these years. We utilized net operating losses from 2000, 2001, 2008 and 2009 in our federal income tax returns for these tax years. The normal statute of limitations for state purposes is between three to five years. However, certain of our state statute of limitations remain open for periods longer than this when audits are in progress. We are subject to income taxes in the United States and numerous foreign jurisdictions. We are subject to examination by various tax authorities in jurisdictions in which we have business operations or a taxable presence. We regularly assess the likelihood of additional assessments by tax authorities and provide for these matters as appropriate. As of December 31, 2015, we had $47,685 of reserves related to uncertain tax positions, of which $45,256 and $2,429 is included in other long-term liabilities and deferred income taxes, respectively, in the accompanying Consolidated Balance Sheet. As of December 31, 2016 , we had $59,466 of reserves related to uncertain tax positions, of which $56,303 and $3,163 is included in other long-term liabilities and deferred income taxes, respectively, in the accompanying Consolidated Balance Sheet. Although we believe our tax estimates are appropriate, the final determination of tax audits and any related litigation could result in changes in our estimates. A rollforward of unrecognized tax benefits is as follows: Gross tax contingencies—December 31, 2013 $ 51,146 Gross additions based on tax positions related to the current year 3,984 Gross additions for tax positions of prior years 13,717 Gross reductions for tax positions of prior years (2,699 ) Lapses of statutes (5,350 ) Settlements (4,847 ) Gross tax contingencies—December 31, 2014 $ 55,951 Gross additions based on tax positions related to the current year 3,484 Gross additions for tax positions of prior years 979 Gross reductions for tax positions of prior years (3,588 ) Lapses of statutes (9,141 ) Settlements — Gross tax contingencies—December 31, 2015 $ 47,685 Gross additions based on tax positions related to the current year 3,704 Gross additions for tax positions of prior years(1) 12,207 Gross reductions for tax positions of prior years (1,740 ) Lapses of statutes (2,390 ) Settlements — Gross tax contingencies—December 31, 2016 $ 59,466 _______________________________________________________________________________ (1) This amount includes gross additions related to the Recall Transaction. The reversal of these reserves of $59,466 ( $47,474 net of federal tax benefit) as of December 31, 2016 will be recorded as a reduction of our income tax provision, if sustained. We believe that it is reasonably possible that an amount up to approximately $18,387 ( $9,085 net of federal tax benefit) of our unrecognized tax positions may be recognized by the end of 2017 as a result of a lapse of statute of limitations or upon closing and settling significant audits in various worldwide jurisdictions.

The debt extinguishment charge, the increase in the provision for income taxes and the decrease in operating income during the fourth quarter of 2015 was offset by a decrease in loss on foreign currency transactions recorded in the fourth quarter of 2015 compared to the third quarter of 2015 of approximately $18,100 . (2) The change in net income (loss) attributable to Iron Mountain Incorporated in the fourth quarter of 2016 compared to the third quarter of 2016 is primarily attributable to a decrease in the provision for income taxes recorded in the fourth quarter of 2016 compared to the third quarter of 2016 of approximately $24,600 , a charge of $14,000 recorded in the third quarter of 2016 associated with the anticipated loss on disposal of the Australia Divestment Business, which occurred on October 31, 2016 (see Note 6) and a decrease in loss on foreign currency transaction losses recorded in the fourth quarter of 2016 compared to the third quarter of 2016 of approximately $5,600 .

(2) Cash paid for acquisitions, net of cash acquired for the Other International Business segment for the year ended December 31, 2016 primarily consists of the cash component of the purchase price for the Recall Transaction, as the IMI entity that made the cash payment was an Australian subsidiary. However, the Recall Transaction also benefited the North American Records and Information Management Business, North American Data Management Business and Western European Business segments. The accounting policies of the reportable segments are the same as those described in Note 2. Adjusted EBITDA for each segment is defined as income (loss) from continuing operations before interest expense, net, provision (benefit) for income taxes, depreciation and amortization, and also excludes certain items that we believe are not indicative of our core operating results, specifically: (i) loss (gain) on disposal/write-down of property, plant and equipment (excluding real estate), net; (ii) intangible impairments; (iii) other expense (income), net; (iv) gain on sale of real estate, net of tax; (v) Recall Costs (as defined below); and (vi) costs associated with our conversion to a REIT, excluding REIT compliance costs beginning January 1, 2014 which we expect to recur in future periods ("REIT Costs"). Internally, we use Adjusted EBITDA as the basis for evaluating the performance of, and allocated resources to, our operating segments. A reconciliation of Adjusted EBITDA to income (loss) from continuing operations on a consolidated basis is as follows: Year Ended December 31, 2014 2015 2016 Adjusted EBITDA $ 925,797 $ 920,005 $ 1,087,288 (Add)/Deduct: Gain on Sale of Real Estate, Net of Tax (8,307 ) (850 ) (2,180 ) (Benefit) Provision for Income Taxes (97,275 ) 37,713 44,944 Other Expense, Net 65,187 98,590 44,300 Interest Expense, Net 260,717 263,871 310,662 Loss (Gain) on Disposal/Write-down of Property, Plant and Equipment (Excluding Real Estate), Net 1,065 3,000 1,412 Depreciation and Amortization 353,143 345,464 452,326 Recall Costs(1) — 47,014 131,944 REIT Costs 22,312 — — Income (Loss) from Continuing Operations $ 328,955 $ 125,203 $ 103,880 _______________________________________________________________________________ (1) Includes operating expenditures associated with our acquisition of Recall, including operating expenditures to complete the Recall Transaction, including advisory and professional fees and costs to complete the Divestments required in connection with receipt of regulatory approval and to provide transitional services required to support the divested businesses during a transition period ("Recall Deal Close & Divestment Costs"), as well as operating expenditures to integrate Recall with our existing operations, including moving, severance, facility upgrade, REIT conversion and system upgrade costs ("Recall Integration Costs" and, collectively with Recall Deal Close & Divestment Costs, "Recall Costs").

Commitments and Contingencies

Commitments and Contingencies	12 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	a. Leases Most of our leased facilities are leased under various operating leases that typically have initial lease terms of five to ten years. A majority of these leases have renewal options with one or more five -year options to extend and may have fixed or Consumer Price Index escalation clauses. We also lease equipment under operating leases (primarily computers) which have an average lease life of three years . Vehicles and office equipment are also leased and have remaining lease lives ranging from one to seven years. Total rent expense under all of our operating leases was $255,193 , $242,205 and $321,337 for the years ended December 31, 2014 , 2015 and 2016 , respectively. Estimated minimum future lease payments (excluding common area maintenance charges) include payments for certain renewal periods at our option because failure to renew results in an economic disincentive due to significant capital expenditure costs (e.g., racking structures), thereby making it reasonably assured that we will renew the lease. Such payments in effect at December 31, are as follows: Year Operating Lease Payments Sublease Income Capital Leases 2017 $ 300,524 $ (6,421 ) $ 68,998 2018 269,867 (4,617 ) 62,564 2019 250,251 (3,712 ) 49,553 2020 229,312 (3,032 ) 60,698 2021 210,458 (3,023 ) 29,353 Thereafter 1,182,243 (7,228 ) 158,937 Total minimum lease payments $ 2,442,655 $ (28,033 ) 430,103 Less amounts representing interest (120,243 ) Present value of capital lease obligations $ 309,860 In addition, we have certain contractual obligations related to purchase commitments which require minimum payments as follows: Year Purchase Commitments 2017 $ 56,335 2018 21,321 2019 8,615 2020 1,808 2021 1,152 Thereafter 1,467 $ 90,698 b. Self-Insured Liabilities We are self-insured up to certain limits for costs associated with workers' compensation claims, vehicle accidents, property and general business liabilities, and benefits paid under employee healthcare and short-term disability programs. At December 31, 2015 and 2016 there were $33,508 and $37,368 , respectively, of self-insurance accruals reflected in accrued expenses on our Consolidated Balance Sheets. The measurement of these costs requires the consideration of historical cost experience and judgments about the present and expected levels of cost per claim. We account for these costs primarily through actuarial methods, which develop estimates of the undiscounted liability for claims incurred, including those claims incurred but not reported. These methods provide estimates of future ultimate claim costs based on claims incurred as of the balance sheet date. c. Litigation—General We are involved in litigation from time to time in the ordinary course of business. 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 $20,000 over the next several years, of which certain amounts would be covered by insurance or indemnity arrangements. d. 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. We have been sued by five customers. Four of those lawsuits have been settled and one , a claim asserted by Azienda per i Transporti Autoferrotranviari del Comune di Roma, S.p.A, seeking 42,600 Euro for the loss of its current and historical archives, remains pending. We have also received correspondence from other affected customers, including certain customers demanding payment under various theories of liability. 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 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 this fire. As a result of the sale of the Italian operations, any future statement of operations and cash flow impacts related to the fire will be reflected as discontinued operations. Our policy related to business interruption insurance recoveries is to record gains within other (income) expense, 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. e. 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. f. Brooklyn Fire (Recall) On January 31, 2015, a former Recall leased facility located in Brooklyn, New York was completely destroyed by a fire. Approximately 900,000 cartons of customer records were lost impacting approximately 1,200 customers. No one was injured as a result of the fire. We believe we carry adequate insurance to cover any losses resulting from the fire. There are three pending customer-related lawsuits stemming from the fire, which are being defended by our warehouse legal liability insurer. We have also received correspondence from other customers, under various theories of liability. We deny any liability with respect to the fire and we have referred these claims to our 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. g. Roye Fire (Recall) On January 28, 2002, a former leased Recall records management facility located in Roye, France was destroyed by a fire. Local French authorities conducted an investigation relating to the fire and issued a charge of criminal negligence for non-compliance with security regulations against the Recall entity that leased the facility. We intend to defend this matter vigorously. We are currently corresponding with various customers impacted by the fire who are seeking payment under various theories of liability. There is also pending civil litigation with the owner of the destroyed facility, who is demanding payment for lost rental income and other items. Based on known and expected claims and our expectation of the ultimate outcome of those claims, we believe we carry adequate insurance coverage. We do not expect that this event will have a material impact on our consolidated financial condition, results of operations or cash flows.

Related Party Transactions [Abstract]
Related Party Transactions	Paul F. Deninger, one of our directors, was a senior managing director at Evercore Group L.L.C. ("Evercore") until June 2016. In May 2013, we entered into an agreement with Evercore, which was amended and restated in August 2013 (the "Evercore Engagement"), pursuant to which Evercore agreed to provide financial advisory services to us. In connection with the Evercore Engagement, Mr. Deninger agreed, and Evercore represented, that Mr. Deninger would not be involved with the Evercore Engagement and would not receive any fees or direct compensation in connection with the Evercore Engagement. The Evercore Engagement was approved by the audit committee of our board of directors in accordance with our Related Persons Transaction Policy. For the year ended December 31, 2014, we incurred monthly retention fees which aggregated to $250 associated with the Evercore Engagement. We did not incur any fees under the Evercore Engagement during the years ended December 31, 2015 and 2016.

Compensation and Retirement Disclosure [Abstract]
401(k) Plans	We have a defined contribution plan, which generally covers all non-union United States employees meeting certain service requirements. Eligible employees may elect to defer from 1% to 25% of compensation per pay period up to the amount allowed by the Internal Revenue Code of 1986, as amended. In addition, IME operates a defined contribution plan, which is similar to our United States 401(k) Plan. We make matching contributions based on the amount of an employee's contribution in accordance with the plan documents. We have incurred expenses of $18,306 , $16,355 and $24,407 for the years ended December 31, 2014 , 2015 and 2016 , respectively, associated with these plans.

Stockholders' Equity Matters

Stockholders' Equity Matters	12 Months Ended

Equity [Abstract]
Stockholders' Equity Matters	Our board of directors has adopted a dividend policy under which we have paid, and in the future intend to pay, quarterly cash dividends on our common stock. The amount and timing of future dividends will continue to be subject to the approval of our board of directors, in its sole discretion, and to applicable legal requirements. 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 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 2015 and 2016 , our board of directors declared the following dividends: Declaration Date Dividend Per Share Record Date Total Amount Payment Date 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 August 27, 2015 0.4750 September 11, 2015 100,213 September 30, 2015 October 29, 2015 0.4850 December 1, 2015 102,438 December 15, 2015 February 17, 2016 0.4850 March 7, 2016 102,651 March 21, 2016 May 25, 2016 0.4850 June 6, 2016 127,469 June 24, 2016 July 27, 2016 0.4850 September 12, 2016 127,737 September 30, 2016 October 31, 2016 0.5500 December 15, 2016 145,006 December 30, 2016 _______________________________________________________________________________ During the years ended December 31, 2014 , 2015 and 2016 , we declared distributions to our stockholders of $1,048,905 , $402,565 and $502,863 , respectively. These distributions represent approximately $5.37 per share, $1.91 per share and $2.04 per share for the years ended December 31, 2014 , 2015 and 2016 , respectively, based on the weighted average number of common shares outstanding during each respective year. For 2014, total amounts distributed included the Special Distribution of $700,000 , or $3.61 per share, associated with our conversion to a REIT, of which $560,000 was paid in the form of our common stock and $140,000 was paid in cash. For federal income tax purposes, distributions to our stockholders are generally treated as nonqualified ordinary dividends, qualified ordinary dividends or return of capital. The United States Internal Revenue Service requires historical C corporation earnings and profits to be distributed prior to any REIT distributions, which may affect the character of each distribution to our stockholders, including whether and to what extent each distribution is characterized as a qualified or nonqualified ordinary dividend. For the years ended December 31, 2014 , 2015 and 2016 , the dividends we paid on our common shares were classified as follows: Year Ended December 31, 2014 2015 2016 Nonqualified ordinary dividends 26.4 % 49.3 % 45.5 % Qualified ordinary dividends 56.4 % 39.1 % 21.0 % Return of capital 17.2 % 11.6 % 33.5 % 100.0 % 100.0 % 100.0 % Dividends paid during the years ended December 31, 2014, 2015 and 2016 which were classified as qualified ordinary dividends for federal income tax purposes primarily related to (i) the distribution of certain of our historical C corporation earnings and profits following our conversion to a REIT (with respect to dividends paid during the year ended December 31, 2014) and (ii) the distribution of historical C corporation earnings and profits related to certain acquisitions completed during the years ended December 31, 2015 and 2016 (with respect to dividends paid during the years ended December 31, 2015 and 2016).

Divestitures	Divestments Associated with the Recall Transaction As disclosed in Note 6, in connection with the acquisition of Recall, we sought regulatory approval of the Recall Transaction from the DOJ, the ACCC, the CCB and the CMA and, as part of the regulatory approval process, we agreed to make the Divestments. The assets and liabilities related to the Initial United States Divestments were sold to Access CIG in the Access Sale on May 4, 2016; the assets and liabilities related to the Australia Divestment Business were sold to Housatonic in the Australia Sale on October 31, 2016; the assets and liabilities related to the UK Divestments were sold to Oasis Group in the UK Sale on December 9, 2016; and the assets and liabilities associated with the Seattle/Atlanta Divestments and the Canadian Divestments were sold to ARKIVE in the ARKIVE Sale on December 29, 2016. We have concluded that the Australian Divestment Business and the Iron Mountain Canadian Divestments (collectively, the “Iron Mountain Divestments”) do not meet the criteria to be reported as discontinued operations in our Consolidated Statements of Operations and Consolidated Statements of Cash Flows for the years ended December 31, 2014, 2015 and 2016, respectively, as our decision to divest these businesses does not represent a strategic shift that will have a major effect on our operations and financial results. Accordingly, the revenues and expenses associated with the Iron Mountain Divestments are presented as a component of income (loss) from continuing operations in our Consolidated Statements of Operations for the years ended December 31, 2014, 2015 and 2016 and the cash flows associated with these businesses are presented as a component of cash flows from continuing operations in our Consolidated Statements of Cash Flows for the years ended December 31, 2014, 2015 and 2016 through the closing date of the Australia Sale, in the case of the Australia Divestment Business, and through the closing date of the ARKIVE Sale, in the case of the Iron Mountain Canadian Divestments. During the year ended December 31, 2016, we recorded charges of $15,417 and $1,421 to other expense, net associated with the loss on disposal of the Australia Divestment Business and the Iron Mountain Canadian Divestments, respectively, representing the excess of the carrying value of these businesses compared to their fair value (less costs to sell). We have concluded that the Initial United States Divestments, the Seattle/Atlanta Divestments, the Recall Canadian Divestments and the UK Divestments (collectively, the “Recall Divestments”) meet the criteria to be reported as discontinued operations in our Consolidated Statement of Operations and Consolidated Statement of Cash Flows for the year ended December 31, 2016, as the Recall Divestments met the criteria to be reported as assets and liabilities held for sale at, or within a short period of time following, the closing of the Recall Transaction. The table below summarizes certain results of operations of the Recall Divestments included in discontinued operations: Year Ended December 31, 2016 Description Initial Seattle/Atlanta Divestments Recall Canadian Divestments UK Divestments Total Total Revenues $ — $ 6,077 $ 5,951 $ 1,019 $ 13,047 Income (Loss) from Discontinued Operations Before Provision (Benefit) for Income Taxes — 1,726 2,472 (93 ) 4,105 Provision (Benefit) for Income Taxes — 84 654 14 752 Income (Loss) from Discontinued Operations, Net of Tax $ — $ 1,642 $ 1,818 $ (107 ) $ 3,353 ______________________________________________________________________________ (1) The Access Sale occurred nearly simultaneously with the closing of the Recall Transaction. Accordingly, the revenue and expenses associated with the Initial United States Divestments are not included in our Consolidated Statement of Operations for the year ended December 31, 2016 and the cash flows associated with the Initial United States Divestments are not included in our Consolidated Statement of Cash Flows for the year ended December 31, 2016 , due to the immaterial nature of the revenues, expenses and cash flows related to the Initial United States Divestments for the period of time we owned these businesses (May 2, 2016 through May 4, 2016). The assets subject to the Recall Divestments were acquired in the Recall Transaction and, therefore, the fair value of the Recall Divestments has been reflected in the allocation of the purchase price for Recall as a component of "Fair Value of Recall Divestments". International Shredding Operations In December 2014, we divested our secure shredding operations in Australia, Ireland and the United Kingdom (the "International Shredding Operations") in a stock transaction for approximately $26,200 in cash at closing. The assets sold primarily consisted of customer contracts and certain long-lived assets. We have concluded that this divestiture did not meet the requirements to be presented as a discontinued operation , and, therefore, recorded a pretax gain on sale in other (income) expense, net of approximately $6,900 ( $10,200 , inclusive of a tax benefit) in our Consolidated Statement of Operations for the year ended December 31, 2014. Revenues from our International Shredding Operations represented less than 1% of our consolidated revenues for the year ended December 31, 2014. The International Shredding Operations in Australia were previously included in the Other International Business segment and the International Shredding Operations in the United Kingdom and Ireland were previously included in the Western European Business segment. Digital Operations On June 2, 2011, we sold our online backup and recovery, digital archiving and eDiscovery solutions businesses of our digital business (the “Digital Business”) to Autonomy Corporation plc, a corporation formed under the laws of England and Wales (“Autonomy”), pursuant to a purchase and sale agreement dated as of May 15, 2011 among IMI, certain subsidiaries of IMI and Autonomy (the "Digital Sale"). In the Digital Sale, Autonomy purchased (1) the shares of certain of IMI's subsidiaries through which we conducted the Digital Business and (2) certain assets of IMI and its subsidiaries relating to the Digital Business. The Digital Sale qualified for presentation as a discontinued operation and, as a result, the financial position, operating results and cash flows of the Digital Business, for all periods presented, have been reported as discontinued operations for financial reporting purposes. The table below summarizes certain results of operations of the Digital Business: Year Ended December 31, 2014(1) 2015 2016 (Loss) Income Before (Benefit) Provision for Income Taxes of Discontinued Operations $ (960 ) $ — $ — (Benefit) Provision for Income Taxes — — — (Loss) Income from Discontinued Operations, Net of Tax $ (960 ) $ — $ — _______________________________________________________________________________ (1) During the year ended December 31, 2014, we recognized a loss before (benefit) provision of income taxes of discontinued operations primarily related to settlements of legal matters directly related to the disposed business. Italian Operations We sold our Italian operations on April 27, 2012, and we agreed to indemnify the buyers of our Italian operations for certain possible obligations and contingencies associated with the fire in Italy discussed more fully in Note 10.d. Our Italian operations were previously included within the Western European Business segment. For all periods presented, the financial position, operating results and cash flows of our Italian operations, including the loss on the sale, have been reported as discontinued operations for financial reporting purposes. The table below summarizes certain results of our Italian operations: Year Ended December 31, 2014(1) 2015 2016 Income (Loss) Before (Benefit) Provision for Income Taxes of Discontinued Operations $ 751 $ — $ — (Benefit) Provision for Income Taxes — — — Income (Loss) from Discontinued Operations, Net of Tax $ 751 $ — $ — _______________________________________________________________________________ (1) During the year ended December 31, 2014, we recognized income before (benefit) provision of income taxes of discontinued operations primarily related to the recovery of insurance proceeds in excess of carrying value.

Restructuring and Related Activities [Abstract]
Cost Optimization Plans	Organizational Restructuring During the third quarter of 2013, we implemented a plan that called for certain organizational realignments to advance our growth strategy and reduce operating costs (the “Organizational Restructuring”), which was completed in 2014. As a result of the Organizational Restructuring, we recorded a charge of $3,475 for the year ended December 31, 2014, primarily related to employee severance and associated benefits. Costs included in the accompanying Consolidated Statements of Operations associated with the Organizational Restructuring are as follows: Year Ended December 31, 2014 2015 2016 Cost of sales (excluding depreciation and amortization) $ 1,228 $ — $ — Selling, general and administrative expenses 2,247 — — Total $ 3,475 $ — $ — Costs recorded by segment associated with the Organizational Restructuring are as follows: Year Ended December 31, 2014 2015 2016 North American Records and Information Management Business $ 1,560 $ — $ — North American Data Management Business 340 — — Western European Business 33 — — Other International Business — — — Corporate and Other Business 1,542 — — Total $ 3,475 $ — $ — Transformation Initiative During the third quarter of 2015, we implemented a plan that calls for certain organizational realignments to reduce our overhead costs, particularly in our developed markets, in order to optimize our selling, general and administrative cost structure and to support investments to advance our growth strategy (the “Transformation Initiative”), which is expected to be completed by the end of 2017. As a result of the Transformation Initiative, we recorded charges of $10,167 and $6,007 for the years ended December 31, 2015 and 2016, respectively, primarily related to employee severance and associated benefits. Costs included in the accompanying Consolidated Statements of Operations associated with the Transformation Initiative are as follows: Year Ended December 31, 2014 2015 2016 Cost of sales (excluding depreciation and amortization) $ — $ — $ — Selling, general and administrative expenses — 10,167 6,007 Total $ — $ 10,167 $ 6,007 Costs recorded by segment associated with the Transformation Initiative are as follows: Year Ended December 31, 2014 2015 2016 North American Records and Information Management Business $ — $ 5,403 $ 2,329 North American Data Management Business — 241 395 Western European Business — 1,537 204 Other International Business — — — Corporate and Other Business — 2,986 3,079 Total $ — $ 10,167 $ 6,007 Through December 31, 2016, we have recorded cumulative charges to our Consolidated Statements of Operations associated with the Transformation Initiative of $16,174 . As of December 31, 2016, we had $452 accrued related to the Transformation Initiative. We expect the majority of this liability will be paid in the first half of 2017.

Summary of Significant Accoun28

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2016
Accounting Policies [Abstract]
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America ("GAAP") requires us to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities at the date of the financial statements and for the period then ended. On an ongoing basis, we evaluate the estimates used. We base our estimates on historical experience, actuarial estimates, current conditions and various other assumptions that we believe to be reasonable under the circumstances. These estimates form the basis for making judgments about the carrying values of assets and liabilities and are not readily apparent from other sources. Actual results may differ from these estimates.
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	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 Europe, 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 (i) our previously outstanding 7 1 / 4 % GBP Senior Subordinated Notes due 2014 (the "7 1 / 4 % Notes"), (ii) our previously outstanding 6 3 / 4 % Euro Senior Subordinated Notes due 2018 (the "6 3 / 4 % Notes"), (iii) borrowings in certain foreign currencies under our Revolving Credit Facility and our Former Revolving Credit Facility (each as defined in Note 4) and (iv) 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.
Derivatives Instruments and Hedging Activities	Derivative Instruments and Hedging Activities Every derivative instrument is required to be recorded in the balance sheet as either an asset or a liability measured at its fair value. Periodically, we acquire derivative instruments that are intended to hedge either cash flows or values that are subject to foreign exchange or other market price risk and not for trading purposes. We have formally documented our hedging relationships, including identification of the hedging instruments and the hedged items, as well as our risk management objectives and strategies for undertaking each hedge transaction. Given the recurring nature of our revenues and the long-term nature of our asset base, we have the ability and the preference to use long-term, fixed interest rate debt to finance our business, thereby preserving our long-term returns on invested capital. We target approximately 75% of our debt portfolio to be fixed with respect to interest rates. Occasionally, we may use interest rate swaps as a tool to maintain our targeted level of fixed rate debt. In addition, we may use borrowings in foreign currencies, either obtained in the United States or by our foreign subsidiaries, to hedge foreign currency risk associated with our international investments. Sometimes we enter into currency swaps to temporarily hedge an overseas investment, such as a major acquisition, while we arrange permanent financing or to hedge our exposure due to foreign currency exchange movements related to our intercompany accounts with and between our foreign subsidiaries.
Property, Plant and Equipment	Entities are required to record the fair value of a liability for an asset retirement obligation in the period in which it is incurred. Asset retirement obligations represent the costs to replace or remove tangible long-lived assets required by law, regulatory rule or contractual agreement. When the liability is initially recorded, the entity capitalizes the cost by increasing the carrying amount of the related long-lived asset, which is then depreciated over the useful life of the related asset. The liability is increased over time through accretion expense (included in depreciation expense) such that the liability will equate to the future cost to retire the long-lived asset at the expected retirement date. Upon settlement of the liability, an entity either settles the obligation for its recorded amount or realizes a gain or loss upon settlement. Our asset retirement obligations are primarily the result of requirements under our facility lease agreements which generally have "return to original condition" clauses which would require us to remove or restore items such as shred pits, vaults, demising walls and office build-outs, among others. The significant assumptions used in estimating our aggregate asset retirement obligation are the timing of removals, the probability of a requirement to perform, estimated cost and associated expected inflation rates that are consistent with historical rates and credit-adjusted risk-free rates that approximate our incremental borrowing rate. Minor maintenance costs are expensed as incurred. Major improvements which extend the life, increase the capacity or improve the safety or the efficiency of property owned are capitalized. Major improvements to leased buildings are capitalized as leasehold improvements and depreciated. 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 years ended December 31, 2014 , 2015 and 2016 , we capitalized $19,419 , $26,201 and $16,438 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.
Goodwill and Other Intangible Assets	Goodwill and Other Indefinite-Lived Intangible Assets Goodwill and intangible assets with indefinite lives are not amortized but are reviewed annually for impairment or more frequently if impairment indicators arise. Other than goodwill, we currently have no intangible assets that have indefinite lives and which are not amortized. We have selected October 1 as our annual goodwill impairment review date. As described in more detail below, we performed our annual goodwill impairment review as of October 1, 2014 , 2015 and 2016 , and concluded that goodwill was not impaired as of such dates. As of December 31, 2016 , no factors were identified that would alter our October 1, 2016 goodwill impairment analysis. In making this assessment, we considered 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.
Customer Relationships and Acquisitions Costs and Other Intangible Assets	Customer Relationship Intangible Assets, Customer Inducements and Other Finite-Lived Intangible Assets Customer relationship intangible assets, which are acquired through either business combinations or acquisitions of customer relationships, are amortized over periods ranging from eight to 30 years (weighted average of 18 years at December 31, 2016 ). The value of customer relationship intangible assets is calculated based upon estimates of their fair value utilizing an income approach based on the present value of expected future cash flows. Costs related to the acquisition of large volume accounts are capitalized. Free intake costs to transport boxes to one of our facilities, which include labor and transportation costs ("Move Costs"), are amortized over periods ranging from eight to 30 years (weighted average of 26 years at December 31, 2016 ), and are included in depreciation and amortization in the accompanying Consolidated Statements of Operations. Payments that are made to a customer's current records management vendor in order to terminate the customer's existing contract with that vendor, or direct payments to a customer ("Permanent Withdrawal Fees"), are amortized over periods ranging from three to 15 years (weighted average of eight years at December 31, 2016 ), and are included in storage and service revenue in the accompanying Consolidated Statements of Operations. Move Costs and Permanent Withdrawal Fees are collectively referred to as "Customer Inducements". If the customer terminates its relationship with us, the unamortized carrying value of the Customer Inducement intangible asset is charged to expense or revenue. However, in the event of such termination, we generally collect, and record as income, permanent removal fees that generally equal or exceed the amount of the unamortized Customer Inducement intangible asset. Other finite-lived intangible assets, including trade names, noncompetition agreements and trademarks, are capitalized and amortized over periods ranging from three to 10 years (weighted average of eight years at December 31, 2016 ).
Deferred Financing Costs	Deferred Financing Costs Deferred financing costs are amortized over the life of the related debt using the effective interest rate method. If debt is retired early, the related unamortized deferred financing costs are written off in the period the debt is retired to other expense (income), net.
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) and technology escrow services that protect and manage source code. 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 ("Information Governance and Digital Solutions") which relate to physical and digital records, and project revenues; (5) customer termination and permanent removal fees; (6) data restoration projects; (7) special project work; (8) the storage, assembly, reporting and delivery of customer marketing literature, or fulfillment services; (9) consulting services; and (10) other technology services and product sales (including specially designed storage containers and related supplies). We recognize revenue when the following criteria are met: (1) persuasive evidence of an arrangement exists; (2) services have been rendered; (3) the sales price is fixed or determinable; and (4) 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, which represented less than 2% of consolidated revenue for the year ended December 31, 2016, have historically not been significant. 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 guidance for management to reassess revenue recognition as it relates to: (1) transfer of control, (2) variable consideration, (3) allocation of transaction price based on relative standalone selling price, (4) licenses, (5) time value of money, and (6) contract costs. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date ("ASU 2015-14"). ASU 2015-14 deferred the effective date of ASU 2014-09 for one year, making it effective for us on January 1, 2018, with early adoption permitted as of January 1, 2017. We will adopt ASU 2014-09 as of January 1, 2018. See Note 2.w. for additional information on ASU 2014-09.
Rent Normalization	Rent Normalization We have entered into various leases for buildings that expire over various terms. Certain leases have fixed escalation clauses (excluding those tied to the consumer price index or other inflation-based indices) or other features (including return to original condition, primarily in the United Kingdom) which require normalization of the rental expense over the life of the lease, resulting in deferred rent being reflected as a liability in the accompanying Consolidated Balance Sheets. In addition, we have assumed various above and below market leases in connection with certain of our acquisitions. The difference between the present value of these lease obligations and the market rate at the date of the acquisition was recorded as either a deferred rent liability or deferred rent asset (which is a component of Other within Other Assets, net in our Consolidated Balance Sheets) and is being amortized to rent expense.
Stock-Based Compensation	Our equity compensation plans generally provide that any unvested options and other awards granted thereunder shall vest immediately if an employee is terminated, or terminates their own employment for good reason (as defined in each plan), in connection with a vesting change in control (as defined in each plan). On January 20, 2015, our stockholders approved the adoption of the Iron Mountain Incorporated 2014 Stock and Cash Incentive Plan (the "2014 Plan"). Performance Units Under our various equity compensation plans, we may also make awards of PUs. For the majority of outstanding PUs, the number of PUs earned is determined based on our performance against predefined targets of revenue and return on invested capital ("ROIC"). The number of PUs earned may range from 0% to 200% of the initial award. The number of PUs earned is determined based on our actual performance as compared to the targets at the end of a three -year performance period. Certain PUs that we grant will be earned based on a market condition associated with the total return on our common stock in relation to a subset of the Standard & Poor's 500 Index rather than the revenue 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. PUs awarded to employees who terminate their employment during the three -year performance period and on or after attaining age 55 and completing 10 years of qualifying service are eligible for pro-rated vesting, subject to the actual achievement against the predefined targets or a market condition as discussed above, based on the number of full years of service completed following the grant date (but delivery of the shares remains deferred). As a result, PUs are generally expensed over the three-year performance period. All PUs accrue dividend equivalents associated with the underlying stock as we declare dividends. Dividends will generally be paid to holders of PUs in cash upon the settlement date of the associated PU and will be forfeited if the PU does not vest. Under our various equity compensation plans, we may also grant RSUs. Our RSUs generally have a vesting period of between three and five years from the date of grant. However, RSUs granted to our non-employee directors in 2015 and thereafter vest immediately upon grant. All RSUs accrue dividend equivalents associated with the underlying stock as we declare dividends. Dividends will generally be paid to holders of RSUs in cash upon the vesting date of the associated RSU and will be forfeited if the RSU does not vest. The fair value of RSUs is the excess of the market price of our common stock at the date of grant over the purchase price (which is typically zero). 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. Stock-Based Compensation We record stock-based compensation expense, utilizing the straight-line method, for the cost of stock options, restricted stock units ("RSUs"), performance units ("PUs") and shares of stock issued under our employee stock purchase plan ("ESPP") (together, "Employee Stock-Based Awards"). 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. The options we issue become exercisable ratably over a period of either (i) 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, (ii) 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, or (iii) 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. 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.
Income Taxes	Income Taxes Accounting for income taxes requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the tax and financial reporting bases of assets and liabilities and for loss and credit carryforwards. Valuation allowances are provided when recovery of deferred tax assets does not meet the more likely than not standard as defined in GAAP. We have elected to recognize interest and penalties associated with uncertain tax positions as a component of the (benefit) provision for income taxes in the accompanying Consolidated Statements of Operations.
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 stock options, RSUs, PUs, warrants or convertible securities) that were outstanding during the period, unless the effect is antidilutive.
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.
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 have elected the cost 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.
New Accounting Pronouncements	New Accounting Pronouncements Recently Adopted Accounting Pronouncements 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, ASU 2014-15 (1) provides a definition of the term “substantial doubt”, (2) requires an evaluation every reporting period, including interim periods, (3) provides principles for considering the mitigating effect of management’s plans, (4) requires certain disclosures when substantial doubt is alleviated as a result of consideration of management’s plans, (5) requires an express statement and other disclosures when substantial doubt is still present, and (6) requires 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 fiscal years ending after December 15, 2016. We adopted ASU 2014-15 during the fourth quarter of 2016. The adoption of ASU 2014-15 did not 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. We adopted ASU 2015-02 effective as of January 1, 2016. The adoption of ASU 2015-02 did not have an impact on our consolidated financial statements. In November 2015, the FASB issued ASU No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes ("ASU 2015-17"). ASU 2015-17 eliminates the requirement for reporting entities to present deferred tax liabilities and assets as current and noncurrent in a classified balance sheet. Instead, reporting entities will be required to classify all deferred tax liabilities and assets as noncurrent. We adopted ASU 2015-17 during the fourth quarter of 2016 and have applied the provisions of ASU 2015-17 on a prospective basis. Therefore, our Consolidated Balance Sheet as of December 31, 2016 reflects the adoption of ASU 2015-17. Our consolidated balance sheet as of December 31, 2015 does not reflect the adoption of ASU 2015-17. Had we adopted the provisions of ASU 2015-17 on a retrospective basis, the impact on our consolidated balance sheet as of December 31, 2015 would have been (i) a decrease in deferred income taxes (a component of Total Current Assets) of $22,179 , (ii) an increase in other (a component of Other Assets, net) of $18,394 and (iii) a decrease in deferred income taxes (a component of Long-term Liabilities) of $3,785 . In March 2016, the FASB issued ASU No. 2016-07, Simplifying the Transition to the Equity Method of Accounting ("ASU 2016-07"). ASU 2016-07 eliminates the requirement for a reporting entity to apply the equity method of accounting retrospectively when they obtain significant influence over a previously held investment. Furthermore, under ASU 2016-07, for any available-for-sale securities that become eligible for the equity method of accounting, the unrealized gain or loss recorded within other comprehensive income (loss) associated with the securities should be recognized in earnings at the date the investment initially qualifies for the use of the equity method. We adopted ASU 2016-07 on April 1, 2016. The adoption of ASU 2016-07 did not have a material impact on our consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting ("ASU 2016-09"). As noted in Note 2.n., we adopted ASU 2016-09 effective as of January 1, 2016. The adoption of ASU 2016-09 did not have a material impact on our consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”) . ASU 2016-15 addresses eight specific cash flow changes with the objective of reducing existing diversity in the practice of how certain cash receipts and cash payments are presented and classified in the statement of cash flows. We adopted ASU 2016-15 during the third quarter of 2016. ASU 2016-15 did not have an impact on our consolidated financial statements. As Yet Adopted Accounting Pronouncements a. ASU 2014-09 As disclosed in Note 2.l., in May 2014, the FASB issued ASU 2014-09. ASU 2014-09 will replace the current revenue recognition criteria under GAAP, including industry-specific requirements, and provide companies with a single revenue recognition model for recognizing revenue from contracts with customers. The core principle of ASU 2014-09 is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for such goods or services. The two permitted transition methods under ASU 2014-09 are: (i) the full retrospective method, whereby ASU 2014-09 would be applied to each prior reporting period presented and the cumulative effect of adoption would be recognized at the earliest period shown, or (ii) the modified retrospective method, whereby the cumulative effect of applying ASU 2014-09 would be recognized at the date of initial application. In August 2015, the FASB issued ASU No 2015-14 which deferred the effective date of ASU 2014-09 for one year, making ASU 2014-09 effective for us on January 1, 2018, with early adoption permitted as of January 1, 2017. We will adopt ASU 2014-09 on January 1, 2018 using the modified retrospective method. During 2015, we established a project team responsible for the assessment and implementation of ASU 2014-09. We utilized a bottoms-up approach to analyze the impact of ASU 2014-09 on our contracts with customers by reviewing our current accounting policies and practices to identify potential differences that would result from applying the requirements of ASU 2014-09 to our contracts with customers. We are currently in the process of designing and implementing appropriate changes to our business processes, systems and controls to support the accounting and the financial disclosure requirements under ASU 2014-09. We have been closely monitoring the FASB activity related to specific interpretative issues pertaining to ASU 2014-09. During the second half of 2016, we substantially completed our evaluation of the potential changes resulting from the adoption of ASU 2014-09 on our accounting and the financial disclosure requirements and are now moving into the more detailed quantification of the impacts of adopting ASU 2014-09, the more significant of which are discussed below. Based on our analysis to date, we expect that the most significant impacts associated with adopting ASU 2014-09 compared to current GAAP will relate to (i) the deferral of certain commissions on our long-term storage contracts (“Accounting for Commissions”) and (ii) certain policy changes related to initial moves of physical storage, which will be subject to new cost guidance (“Accounting for Initial Moves”). i. Accounting for Commissions Under current GAAP, commissions that we pay related to our long-term storage contracts are expensed as incurred. Under ASU 2014-09, however, certain commissions will be capitalized and amortized over the period of expected earned revenue. In the year of adoption, this will result in increased intangible contract assets on our Consolidated Balance Sheet, a reduction in selling, general and administrative expenses and a corresponding increase in amortization expense (assuming consistent levels of spending up through the adoption date) on our Consolidated Statement of Operations and an increase in cash flows from operating activities and a corresponding increase in cash used for investing activities on our Consolidated Statement of Cash Flows. ii. Accounting for Initial Moves Under current GAAP, free intake costs to transport boxes to one of our facilities, which include labor and transportation costs, are capitalized and amortized as a component of depreciation and amortization in our Consolidated Statements of Operations. Under ASU 2014-09, however, the revenue and costs associated with all initial moves of physical storage, regardless of whether or not the services associated with such initial moves are provided to the customer at no charge, will be deferred and recognized over the period consistent with the transfer of the service to the customer to which the asset relates. In the year of adoption, this will result in decreased intangible assets and increased deferred revenue on our Consolidated Balance Sheet, a reduction in cost of sales and a corresponding increase in amortization expense (assuming consistent levels of spending up through the adoption date) on our Consolidated Statement of Operations and an increase in cash flows from operating activities and a corresponding increase in cash used for investing activities on our Consolidated Statement of Cash Flows. b. Other As Yet Adopted Accounting Pronouncements In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities ("ASU 2016-01"). ASU 2016-01 requires that most equity investments be measured at fair value, with subsequent changes in fair value recognized in net income. The pronouncement also impacts financial liabilities under the fair value option and the presentation and disclosure requirements for financial instruments. ASU 2016-01 is effective for us on January 1, 2018. We do not believe that the adoption of ASU 2016-01 will have a material impact on our consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) ("ASU 2016-02"). ASU 2016-02 requires lessees to recognize assets and liabilities on the balance sheet for the rights and obligations created by all leases with terms of more than 12 months. ASU 2016-02 also will require certain qualitative and quantitative disclosures designed to give financial statement users information on the amount, timing, and uncertainty of cash flows arising from leases. ASU 2016-02 will be effective for us on January 1, 2019, with early adoption permitted. We will adopt ASU 2016-02 on January 1, 2019 and are currently evaluating the impact ASU 2016-02 will have on our consolidated financial statements. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash ("ASU 2016-18"). ASU 2016-18 provides guidance on the classification of restricted cash in the statement of cash flows. ASU 2016-18 is effective for us on January 1, 2018, with early adoption permitted and is required to be adopted on a retrospective basis. We do not believe that the adoption of ASU 2016-18 will have a material impact on our consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business ("ASU 2017-01"). ASU 2017-01 provides greater clarity on the definition of a business to assist entities in evaluating whether transactions should be accounted for as an acquisition or disposal of assets or businesses. ASU 2017-01 is effective for us on January 1, 2018, with early adoption permitted. We do not believe that the adoption of ASU 2017-01 will have a material impact on our consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment ("ASU 2017-04"). ASU 2017-04 modifies the process by which entities will test goodwill for impairment. Under existing GAAP, when the carrying value of a reporting unit exceeds the reporting unit’s fair value, an entity would then proceed to a “Step 2” goodwill impairment analysis, which requires calculating the implied fair value of goodwill by assigning the fair value of a reporting unit to all of its assets and liabilities, as if that reporting unit had been acquired in a business combination. Under ASU 2017-04, a goodwill impairment will be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying value of the reporting unit’s goodwill. ASU 2017-04 is effective for us on January 1, 2020, with early adoption permitted. We do not believe ASU 2017-04 will have a material impact on our consolidated financial statements. x. Redeemable Noncontrolling Interests Certain unaffiliated third parties own noncontrolling interests in our consolidated subsidiaries in Chile, India and South Africa. The underlying shareholder agreements between us and our noncontrolling interest shareholders for these subsidiaries contain provisions under which the noncontrolling interest shareholders can require us to purchase their respective interests in such subsidiaries at certain times and at a purchase price as stipulated in the underlying shareholder agreements (generally at fair value). These put options make these noncontrolling interests redeemable and, therefore, these noncontrolling interests are classified as temporary equity outside of stockholders' equity. Redeemable noncontrolling interests are reported at the higher of their redemption value or the noncontrolling interest holders' proportionate share of the underlying subsidiaries net carrying value. Increases or decreases in the redemption value of the noncontrolling interest are offset against APIC.
