Nature of Business
Nature of Business
	1. Nature of Business
	The accompanying financial statements represent the consolidated accounts of Iron Mountain Incorporated, a Delaware corporation (“IMI”) and its subsidiaries (“we” or “us”). We store records, primarily paper documents and data backup media, and provide information management services in various locations throughout North America, Europe, Latin America and Asia Pacific. We have a diversified customer base consisting of commercial, legal, banking, healthcare, accounting, insurance, entertainment and government organizations.
	We previously disclosed that, as part of our plan to convert to a real estate investment trust (“REIT”) for federal income tax purposes and elect REIT status effective January 1, 2014 (the “Conversion Plan”), we sought private letter rulings (“PLRs”) from the United States Internal Revenue Service (the “IRS”) relating to numerous technical tax issues, including classification of our steel racking structures as qualified real estate assets. We submitted the PLR requests in the third quarter of 2012, and on June 25, 2014, we announced that we received the favorable PLRs from the IRS necessary for our conversion to a REIT. After receipt of the PLRs, our board of directors unanimously approved our conversion to a REIT for our taxable year beginning January 1, 2014.
	In connection with the Conversion Plan, and, in particular, to impose ownership limitations customary for REITs, on January 20, 2015, we completed the merger with our predecessor and all outstanding shares of our predecessor’s common stock were converted into a right to receive an equal number of shares of our common stock. Accordingly, references herein to our “common stock” refer to our common stock and the common stock of our predecessor, as applicable.
	On June 2, 2011, we sold (the “Digital Sale”) 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 Agreement”). Additionally, on October 3, 2011, we sold our records management operations in New Zealand. Also, on April 27, 2012, we sold our records management operations in Italy. The financial position, operating results and cash flows of the Digital Business, our New Zealand operations and our Italian operations, including the gain on the sale of the Digital Business and our New Zealand operations and the loss on the sale of our Italian operations, for all periods presented, have been reported as discontinued operations for financial reporting purposes. See Note 14 for a further discussion of these events.

	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.
	We have restricted cash associated with a collateral trust agreement with our insurance carrier related to our workers’ compensation self-insurance program. The restricted cash subject to this agreement was $33,860 as of both December 31, 2013 and 2014, and is included in current assets on our Consolidated Balance Sheets. Restricted cash consists primarily of United States Treasuries.
	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 Switzerland, whose functional currency is the United States dollar. In those instances where the local currency is the functional currency, assets and liabilities are translated at period-end exchange rates, and revenues and expenses are translated at average exchange rates for the applicable period. Resulting translation adjustments are reflected in the accumulated other comprehensive items, net component of Iron Mountain Incorporated Stockholders’ Equity and Noncontrolling Interests in the accompanying Consolidated Balance Sheets. The gain or loss on foreign currency transactions, calculated as the difference between the historical exchange rate and the exchange rate at the applicable measurement date, including those related to (1) our previously outstanding 71/4% GBP Senior Subordinated Notes due 2014 (the “71/4% Notes”), (2) our 63/4% Euro Senior Subordinated Notes due 2018 (the “63/4% Notes”), (3) the borrowings in certain foreign currencies under our revolving credit facility and (4) certain foreign currency denominated intercompany obligations of our foreign subsidiaries to us and between our foreign subsidiaries, which are not considered permanently invested, are included in other expense (income), net, in the accompanying Consolidated Statements of Operations. The total loss on foreign currency transactions amounted to $10,223, $36,201 and $58,316 for the years ended December 31, 2012, 2013 and 2014, respectively.
	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, 2013 and 2014, none of our derivative instruments contained credit-risk related contingent features.
	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	3 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,
			2013		2014
	Land		$		$
			203,423		205,463
	Buildings and building improvements		1,283,458		1,409,330

	Furniture and fixtures		53,590		53,189
	Computer hardware and software		511,927		501,882
	Construction in progress		177,380		130,889
			$		$
			4,631,067		4,668,705
	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, 2012, 2013 and 2014, we capitalized $26,755, $39,487 and $19,419 of costs, respectively, associated with the development of internal use computer software projects. Capitalization begins when the design stage of the application has been completed and it is probable that the project will be completed and used to perform the function intended. Capitalization ends when the asset is ready for its intended use. Depreciation begins when the software is placed in service. Computer software costs that are capitalized are periodically evaluated for impairment.
	We 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,

	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 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,

	Asset Retirement Obligations, beginning of the year		$		$

	g.Goodwill and Other Intangible Assets
	Goodwill and intangible assets with indefinite lives are not amortized but are reviewed annually for impairment or more frequently if impairment indicators arise. Other than goodwill, we currently have no intangible assets that have indefinite lives and which are not amortized. Separable intangible assets that are not deemed to have indefinite lives are amortized over their useful lives. We annually, or more frequently if events or circumstances warrant, assess whether a change in the lives over which our intangible assets are amortized is necessary.
	We have selected October 1 as our annual goodwill impairment review date. We performed our annual goodwill impairment review as of October 1, 2012, 2013 and 2014 and concluded that goodwill was not impaired as of those dates. As of December 31, 2014, no factors were identified that would alter our October 1, 2014 goodwill assessment. In making this assessment, we relied on a number of factors including operating results, business plans, anticipated future cash flows, transactions and marketplace data. There are inherent uncertainties related to these factors and our judgment in applying them to the analysis of goodwill impairment. When changes occur in the composition of one or more reporting units, the goodwill is reassigned to the reporting units affected based on their relative fair values.
Our reporting units at which level we performed our goodwill impairment analysis as of October 1, 2013 were as follows: (1) North America; (2) United Kingdom, Ireland, Norway, Belgium, France, Germany, Netherlands and Spain (“Western Europe”); (3) the remaining countries in Europe in which we operate, excluding Russia and Ukraine (“Emerging Markets”); (4) Latin America; (5) Australia, China, Hong Kong and Singapore (“Asia Pacific”); and (6) India, Russia and Ukraine (“Emerging Market Joint Ventures”). The carrying value of goodwill, net for each of these reporting units as of December 31, 2013 is as follows:
		Carrying Value as of
		December 31, 2013
North America		$
		1,849,440
Western Europe		375,954
Emerging Markets(1)		88,599
Latin America		93,149
Asia Pacific		56,210
Emerging Market Joint Ventures		—
Total		$
		2,463,352
	-1		As of December 31, 2013, the goodwill associated with our operations in Austria and Switzerland was included in the Emerging Markets reporting unit. Beginning January 1, 2014, the goodwill associated with our operations in Austria and Switzerland is included in the New Western Europe reporting unit (defined below).
Beginning January 1, 2014, as a result of the changes in our reportable operating segments associated with our 2014 reorganization, we had four reportable operating segments: (1) North American Records and Information Management Business segment, (2) North American Data Management Business segment, (3) the former International Business segment and (4) Corporate and Other Business segment. The North American Records and Information Management Business segment includes the following three reporting units: (1) North American Records and Information Management; (2) Intellectual Property Management; and (3) Fulfillment Services. The North American Data Management Business segment is a separate reporting unit. The Emerging Businesses reporting unit, which primarily relates to our data center business in the United States, is a component of the Corporate and Other Business segment. Additionally, the former International Business segment consists of the following seven reporting units: (1) United Kingdom, Ireland, Norway, Austria, Belgium, France, Germany, Netherlands, Spain and Switzerland (“New Western Europe”); (2) the remaining countries in Europe in which we operate, excluding Russia, Ukraine and Denmark (“New Emerging Markets”); (3) Latin America; (4) Australia and Singapore; (5) China and Hong Kong (“Greater China”); (6) India; and (7) Russia, Ukraine and Denmark. We have reassigned goodwill associated with the reporting units impacted by the 2014 reorganization among the new reporting units on a relative fair value basis. The fair value of each of our new reporting units was determined based on the application of a combined weighted average approach of fair value multiples of revenue and earnings and discounted cash flow techniques.
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, we performed an interim goodwill impairment test as of January 1, 2014 on the basis of these new reporting units during the first quarter of 2014. We concluded that the goodwill for each of our new reporting units was not impaired as of such date. The carrying value of goodwill, net for each of these reporting units as of December 31, 2014 is as follows:
		Carrying Value as of
		December 31, 2014

As a result of a realignment in senior management reporting structure during the first quarter of 2015, we modified our internal financial reporting to better align internal reporting with how we manage our business. These modifications resulted in the separation of our former International Business segment into two unique reportable operating segments, which we refer to as (1) Western European Business segment and (2) Other International Business segment. See Note 9 for a description of our reportable operating segments.
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, discount 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, 2013 and 2014 is as follows:

	-2		Total fair value and other adjustments primarily include $(32,265) in net adjustments to deferred income taxes and $(443) related to property, plant and equipment and other assumed liabilities, as well as $(1,300) of cash received related to certain 2013 acquisitions.
h.Long-Lived Assets
We review long-lived assets and all amortizable intangible assets for impairment whenever events or changes in circumstances indicate the carrying amount of such assets may not be recoverable. Recoverability of these assets is determined by comparing the forecasted undiscounted net cash flows of the operation to which the assets relate to their carrying amount. The operations are generally distinguished by the business segment and geographic region in which they operate. If the operation is determined to be unable to recover the carrying amount of its assets, the long-lived assets are written down, on a pro rata basis, to fair value. Fair value is determined based on discounted cash flows or appraised values, depending upon the nature of the assets.
As a result of our conversion to a REIT and in accordance with Securities and Exchange Commission (“SEC”) rules applicable to REITs, we no longer report (gain) loss on sale of real estate as a component of operating income, but we will continue to report it as a component of income (loss) from continuing operations. We will continue to report the (gain) loss on sale of property, plant and equipment (excluding real estate), along with any impairment, write- downs or involuntary conversions related to real estate, as a component of operating income. Previously reported amounts have been reclassified to conform to this presentation.
Consolidated loss on disposal/write-down of property, plant and equipment (excluding real estate), net was $4,661 for the year ended December 31, 2012 and consisted primarily of approximately $3,800, $2,500, $700 and $1,100 of asset write-offs in our Other International Business, Western European Business, North American Records and Information Management Business and Emerging Businesses segments, respectively, partially offset by approximately $3,500 of gains associated with the retirement of leased vehicles accounted for as capital lease assets 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 $430 for the year ended December 31, 2013 and consisted of $1,700 of asset write-offs in our North American Records and Information Management Business segment, approximately $300 of asset write-offs in our Corporate and Other Business segment, approximately $600 of asset write-offs associated with our Western European Business segment and approximately $300 of asset write-offs associated with our Other International Business segment, offset by gains of approximately $2,500 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 $1,065 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.
Gain on sale of real estate, net of tax, which consists primarily of the sale of buildings in the United Kingdom, for the years ended December 31, 2012, 2013 and 2014 is as follows:

i.Customer Relationships and Acquisition Costs and Other Intangible Assets
Costs related to the acquisition of large volume accounts are capitalized. Initial costs incurred to transport boxes to one of our facilities, which include labor and transportation charges, are amortized over periods ranging from one to 30 years (weighted average of 25 years at December 31, 2014), and are included in depreciation and amortization in the accompanying Consolidated Statements of Operations. Payments to a customer’s current records management vendor or direct payments to a customer are amortized over periods ranging from one to 15 years (weighted average of six years at December 31, 2014) to the storage and service revenue line items in the accompanying Consolidated Statements of Operations. If the customer terminates its relationship with us, the unamortized cost 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 costs. Customer relationship intangible assets acquired through business combinations, which represents the majority of the balance, are amortized over periods ranging from 10 to 30 years (weighted average of 20 years at December 31, 2014). Amounts allocated in purchase accounting to customer relationship intangible assets are calculated based upon estimates of their fair value utilizing an income approach based on the present value of expected future cash flows. Other intangible assets, including noncompetition agreements, acquired core technology and trademarks, are capitalized and amortized over periods ranging from five to 10 years (weighted average of six years at December 31, 2014).

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, 2013 and 2014, gross carrying amount of deferred financing costs was $62,418 and $63,033, respectively, and accumulated amortization of those costs was $16,811 and $15,956, respectively, and was recorded in other assets, net in the accompanying Consolidated Balance Sheets.
Estimated amortization expense for deferred financing costs, which are amortized as a component of interest expense, is as follows:
		Estimated Amortization of
		Deferred Financing Costs

Other		151,294		153,795
Accrued expenses		$		$
		461,338		404,485
l.Revenues
Our revenues consist of storage rental revenues as well as service revenues and are reflected net of sales and value added taxes. Storage rental revenues, which are considered a key driver of financial performance for the storage and information management services industry, consist primarily of recurring periodic rental charges related to the storage of materials or data (generally on a per unit basis). Service revenues include charges for related service activities, which include: (1) the handling of records, including the addition of new records, temporary removal of records from storage, refiling of removed records and the destruction of records; (2) courier operations, consisting primarily of the pickup and delivery of records upon customer request; (3) secure shredding of sensitive documents and the related sale of recycled paper, the price of which can fluctuate from period to period; (4) other services, including the scanning, imaging and document conversion services of active and inactive records, or Document Management Solutions (“DMS”), which relate to physical and digital records, and project revenues; (5) customer termination and permanent withdrawal fees; (6) data restoration projects; (7) special project work; (8) the storage, assembly, and detailed reporting of customer marketing literature and delivery to sales offices, trade shows and prospective customers’ sites based on current and prospective customer orders (“Fulfillment Services”); (9) consulting services; and (10) technology escrow services that protect and manage source code (“Intellectual Property Management”) and other technology services and product sales (including specially designed storage containers and related supplies).
We recognize revenue when the following criteria are met: persuasive evidence of an arrangement exists, services have been rendered, the sales price is fixed or determinable and collectability of the resulting receivable is reasonably assured. Storage rental and service revenues are recognized in the month the respective storage rental or service is provided, and customers are generally billed on a monthly basis on contractually agreed-upon terms. Amounts related to future storage rental or prepaid service contracts for customers where storage rental fees or services are billed in advance are accounted for as deferred revenue and recognized ratably over the period the applicable storage rental or service is provided or performed. Revenues from the sales of products, which are included as a component of service revenues, are recognized when products are shipped and title has passed to the customer. Revenues from the sales of products have historically not been significant.
m.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 a deferred rent liability or other long-term asset and is being amortized to rent expense over the remaining lives of the respective leases.
n.Stock-Based Compensation
We record stock-based compensation expense, utilizing the straight-line method, for the cost of stock options, restricted stock, restricted stock units (“RSUs”), performance units (“PUs”) and shares of stock issued under our employee stock purchase plan (“ESPP”) (together, “Employee Stock-Based Awards”).
Stock-based compensation expense for Employee Stock-Based Awards included in the accompanying Consolidated Statements of Operations for the years ended December 31, 2012, 2013 and 2014 was $30,360 ($23,437 after tax or $0.14 per basic and $0.13 per diluted share), $30,354 ($22,085 after tax or $0.12 per basic and $0.11 per diluted share) and $29,624 ($21,886 after tax or $0.11 per basic and diluted share), respectively.
Stock-based compensation expense for Employee Stock-Based Awards included in the accompanying Consolidated Statements of Operations related to continuing operations is as follows:
		Year Ended December 31,
		2012		2013	2014
Cost of sales (excluding depreciation and amortization)		$		$	$
		1,392		293	680
Selling, general and administrative expenses		28,968		30,061	28,944
Total stock-based compensation		$		$	$
		30,360		30,354	29,624
The benefits associated with the tax deductions in excess of recognized compensation cost are required to be reported as financing activities in the accompanying Consolidated Statements of Cash Flows. This requirement reduces reported operating cash flows and increases reported financing cash flows. As a result, net financing cash flows from continuing operations included $1,045, $2,389 and $(60) for the years ended December 31, 2012, 2013 and 2014, respectively, from the benefits (deficiency) of tax deductions compared to recognized compensation cost. The tax benefit of any resulting excess tax deduction increases the Additional Paid-in Capital (“APIC”) pool. Any resulting tax deficiency is deducted from the APIC pool.
Stock Options
Under our various stock option plans, options are generally granted with exercise prices equal to the market price of the stock on the date of grant; however, in certain limited instances, options are granted at prices greater than the market price of the stock on the date of grant. The majority of our options become exercisable ratably over a period of five years from the date of grant and generally have a contractual life of ten years from the date of grant, unless the holder’s employment is terminated sooner. Certain of the options we issue become exercisable ratably over a period of ten years from the date of grant and have a contractual life of 12 years from the date of grant, unless the holder’s employment is terminated sooner. As of December 31, 2014, ten-year vesting options represented 8.0% of total outstanding options. Certain of the options we issue become exercisable ratably over a period of three years from the date of grant and have a contractual life of ten years from the date of grant, unless the holder’s employment is terminated sooner. As of December 31, 2014, three-year vesting options represented 34.3% of total outstanding options. Our non-employee directors are considered employees for purposes of our stock option plans and stock option reporting. Options granted to our non-employee directors generally become exercisable one year from the date of grant.
Our equity compensation plans generally provide that any unvested options and other awards granted thereunder shall vest immediately if an employee is terminated by the Company, or terminates his or her 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”). Under the 2014 Plan, the total amount of shares of common stock reserved and available for issuance pursuant to awards granted under the 2014 Plan is 7,750,000. The 2014 Plan permits the Company to continue to grant awards through January 20, 2025.
A total of 43,253,839 shares of common stock have been reserved for grants of options and other rights under our various stock incentive plans, including the 2014 Plan. The number of shares available for grant under our various stock incentive plans, not including the 2014 Plan, at December 31, 2014 was 4,581,754.
The weighted average fair value of options granted in 2012, 2013 and 2014 was $7.00, $7.69 and $5.70 per share, respectively. These values were estimated on the date of grant using the Black-Scholes option pricing model. The following table summarizes the weighted average assumptions used for grants in the year ended December 31:
Weighted Average Assumptions		2012		2013	2014
Expected volatility		33.8%		33.8%	34.0%
Risk-free interest rate		1.24%		1.13%	2.04%
Expected dividend yield		3%		3%	4%
Expected life		6.3 years		6.3 years	6.7 years
Expected volatility is calculated utilizing daily historical volatility over a period that equates to the expected life of the option. The risk-free interest rate was based on the United States Treasury interest rates whose term is consistent with the expected life of the stock options. Expected dividend yield is considered in the option pricing model and represents our current annualized expected per share dividends over the current trade price of our common stock. The expected life (estimated period of time outstanding) of the stock options granted is estimated using the historical exercise behavior of employees.
A summary of option activity for the year ended December 31, 2014 is as follows:
		Options		Weighted	Weighted	Aggregate
				Average	Average	Intrinsic
				Exercise	Remaining	Value
				Price	Contractual

Restricted Stock and Restricted Stock Units
Under our various equity compensation plans, we may also grant restricted stock or RSUs. Our restricted stock and RSUs generally have a vesting period of between three and five years from the date of grant. 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. We accrued approximately $1,378, $1,854 and $3,698 of cash dividends on RSUs for the years ended December 31, 2012, 2013 and 2014, respectively. We paid approximately $58, $820 and $1,377 of cash dividends on RSUs for the years ended December 31, 2012, 2013 and 2014, respectively. The fair value of restricted stock and RSUs is the excess of the market price of our common stock at the date of grant over the purchase price (which is typically zero).
A summary of restricted stock and RSU activity for the year ended December 31, 2014 is as follows:
		Restricted		Weighted-
		Stock and		Average
		RSUs		Grant-Date
				Fair Value
Non-vested at December 31, 2013		1,435,230		$
				29.76
Granted		902,702		29.73
Vested		-721,533		31.24
Forfeited		-210,830		31.14
Non-vested at December 31, 2014		1,405,569		$
				28.78
The total fair value of restricted stock vested for each of the years ended December 31, 2012, 2013 and 2014 was $1. The total fair value of RSUs vested for the years ended December 31, 2012, 2013 and 2014 was $8,296, $16,638 and $22,535, respectively.
Performance Units
Under our various equity compensation plans, we may also make awards of PUs. For the majority of PUs, the number of PUs earned is determined based on our performance against predefined targets of revenue or revenue growth and return on invested capital (“ROIC”). The number of PUs earned may range from 0% to 150% (for PUs granted prior to 2014) and 0% to 200% (for PUs granted in 2014) of the initial award. The number of PUs earned is determined based on our actual performance as compared to the targets at the end of either the one-year performance period (for PUs granted prior to 2014) or the three-year performance period (for PUs granted in 2014). Certain PUs granted in 2013 and 2014 will be earned based on a market condition associated with the total return on our common stock in relation to a subset of the S&P 500 rather than the revenue growth and ROIC targets noted above. The number of PUs earned based on this market condition may range from 0% to 200% of the initial award. All of our PUs will be settled in shares of our common stock and are subject to cliff vesting three years from the date of the original PU grant. For those PUs subject to a one-year performance period, employees who subsequently terminate their employment after the end of the one-year performance period and on or after attaining age 55 and completing 10 years of qualifying service (the “retirement criteria”) shall immediately and completely vest in any PUs earned based on the actual achievement against the predefined targets as discussed above (but delivery of the shares remains deferred). As a result, PUs subject to a one-year performance period are generally expensed over the shorter of (1) the vesting period, (2) achievement of the retirement criteria, which may occur as early as January 1 of the year following the year of grant or (3) a maximum of three years. Outstanding PUs accrue dividend equivalents associated with the underlying stock as we declare dividends. Dividends will generally be paid to holders of PUs in cash upon the settlement date of the associated PU and will be forfeited if the PU does not vest. We accrued approximately $369, $681 and $1,341 of cash dividends on PUs for the years ended December 31, 2012, 2013 and 2014, respectively. There were no cash dividends paid on PUs for the years ended December 31, 2012 and 2013. We paid approximately $312 of cash dividends on PUs for the year ended December 31, 2014.
In 2012, 2013 and 2014, we issued 221,781, 198,869 and 225,429 PUs, respectively. Our PUs are earned based on our performance against revenue or revenue growth and ROIC targets during their applicable performance period; therefore, we forecast the likelihood of achieving the predefined revenue, revenue growth and ROIC targets in order to calculate the expected PUs to be earned. We record a compensation charge based on either the forecasted PUs to be earned (during the applicable performance period) or the actual PUs earned (at the one-year anniversary date for PUs granted prior to 2014, and at the three-year anniversary date for PUs granted in 2014) over the vesting period for each of the awards. For the 2013 and 2014 PUs that will be earned based on a market condition, we utilized a Monte Carlo simulation to fair value these awards at the date of grant, and such fair value will be expensed over the three-year performance period. The total fair value of earned PUs that vested during the years ended December 31, 2012, 2013 and 2014 was $4,285, $2,962 and $1,216, respectively. As of December 31, 2014, we expected 60% achievement of the predefined revenue, revenue growth and ROIC targets associated with the awards of PUs made in 2014.
A summary of PU activity for the year ended December 31, 2014 is as follows:
		Original		PU Adjustment(1)	Total	Weighted-
		PU Awards			PU Awards	Average
						Grant-Date
						Fair Value
Non-vested at December 31, 2013		334,548		-23,732	310,816	$

Non-vested at December 31, 2014		461,666		-82,609	379,057	$
						30.80
	-1		Represents an increase or decrease in the number of original PUs awarded based on either (a) the final performance criteria achievement at the end of the defined performance period of such PUs or (b) a change in estimated awards based on the forecasted performance against the predefined targets.
Employee Stock Purchase Plan
We offer an ESPP in which participation is available to substantially all United States and Canadian employees who meet certain service eligibility requirements. The ESPP provides a way for our eligible employees to become stockholders on favorable terms. The ESPP provides for the purchase of our common stock by eligible employees through successive offering periods. We have historically had two six-month offering periods per year, the first of which generally runs from June 1 through November 30 and the second of which generally runs from December 1 through May 31. During each offering period, participating employees accumulate after-tax payroll contributions, up to a maximum of 15% of their compensation, to pay the purchase price at the end of the offering. Participating employees may withdraw from an offering before the purchase date and obtain a refund of the amounts withheld as payroll deductions. At the end of the offering period, outstanding options under the ESPP are exercised, and each employee’s accumulated contributions are used to purchase our common stock. The price for shares purchased under the ESPP is 95% of the fair market price at the end of the offering period, without a look-back feature. As a result, we do not recognize compensation expense for the ESPP shares purchased. For the years ended December 31, 2012, 2013 and 2014, there were 151,285 shares, 144,432 shares and 115,046 shares, respectively, purchased under the ESPP. As of December 31, 2014, we have 960,638 shares available under the ESPP.
As of December 31, 2014, unrecognized compensation cost related to the unvested portion of our Employee Stock-Based Awards was $35,467 and is expected to be recognized over a weighted-average period of 1.9 years.
We generally issue shares of our common stock for the exercises of stock options, restricted stock, RSUs, PUs and shares of our common stock under our ESPP from unissued reserved shares.
o.Income Taxes
Accounting for income taxes requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the tax and financial reporting bases of assets and liabilities and for loss and credit carryforwards. Valuation allowances are provided when recovery of deferred tax assets does not meet the more likely than not standard as defined in GAAP. We have elected to recognize interest and penalties associated with uncertain tax positions as a component of the provision (benefit) for income taxes in the accompanying Consolidated Statements of Operations.
p.Income (Loss) Per Share—Basic and Diluted
Basic income (loss) per common share is calculated by dividing income (loss) by the weighted average number of common shares outstanding. The calculation of diluted income (loss) per share is consistent with that of basic income (loss) per share but gives effect to all potential common shares (that is, securities such as options, warrants or convertible securities) that were outstanding during the period, unless the effect is antidilutive.
The following table presents the calculation of basic and diluted income (loss) per share:
		Year Ended December 31,
		2012		2013	2014
Income (loss) from continuing operations		$		$	$
		182,707		99,161	328,955
Total (loss) income from discontinued operations (see Note 14)		$		$	$

Antidilutive stock options, RSUs and PUs, excluded from the calculation		1,286,150		903,416	872,039
q.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.
Rollforward of allowance for doubtful accounts and credit memo reserves is as follows:
Year Ended December 31,		Balance at		Credit Memos	Allowance for	Other(1)	Deductions(2)	Balance at
		Beginning of		Charged to	Bad Debts			End of
		the Year		Revenue	Charged to			the Year
					Expense

2013		25,209		49,483	11,321	3,612	-54,980	34,645
2014		34,645		47,137	14,209	-572	-63,278	32,141
	-1		Primarily consists of recoveries of previously written-off accounts receivable, allowances of businesses acquired and the impact associated with currency translation adjustments.
	-2		Primarily consists of the issuance of credit memos and the write-off of accounts receivable.
r.Concentrations of Credit Risk
Financial instruments that potentially subject us to credit risk consist principally of cash and cash equivalents (including money market funds and time deposits), restricted cash (primarily United States Treasuries) and accounts receivable. The only significant concentrations of liquid investments as of both December 31, 2013 and 2014 relate to cash and cash equivalents and restricted cash held on deposit with one global bank and one “Triple A” rated money market fund, and three global banks and two “Triple A” rated money market funds, respectively, all of which we consider to be large, highly-rated investment-grade institutions. As per our risk management investment policy, we limit exposure to concentration of credit risk by limiting the amount invested in any one mutual fund to a maximum of $50,000 or in any one financial institution to a maximum of $75,000. As of December 31, 2013 and 2014, our cash and cash equivalents and restricted cash balance was $154,386 and $159,793, respectively, including money market funds and time deposits amounting to $36,613 and $53,032 respectively. The money market funds are invested substantially in United States Treasuries.
s.Fair Value Measurements
Entities are permitted under GAAP to elect to measure many financial instruments and certain other items at either fair value or cost. We did not elect the fair value measurement option.
Our financial assets or liabilities that are carried at fair value are required to be measured using inputs from the three levels of the fair value hierarchy. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.
The three levels of the fair value hierarchy are as follows:
Level 1—Inputs are unadjusted quoted prices in active markets for identical assets or liabilities that we have the ability to access at the measurement date.
Level 2—Inputs include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (i.e., interest rates, yield curves, etc.), and inputs that are derived principally from or corroborated by observable market data by correlation or other means (market corroborated inputs).
Level 3—Unobservable inputs that reflect our assumptions about the assumptions that market participants would use in pricing the asset or liability.
The following tables provide the assets and liabilities carried at fair value measured on a recurring basis as of December 31, 2013 and 2014, respectively:
				Fair Value Measurements at

	-1		Money market funds and time deposits (including certain trading securities) are measured based on quoted prices for similar assets and/or subsequent transactions.
	-2		Securities are measured at fair value using quoted market prices.
	-3		Our derivative assets and liabilities primarily relate to short- term (six months or less) foreign currency contracts that we have entered into to hedge certain of our intercompany exposures, as more fully disclosed at Note 3. We calculate the fair value of such forward contracts by adjusting the spot rate utilized at the balance sheet date for translation purposes by an estimate of the forward points observed in active markets.
Disclosures are required in the financial statements for items measured at fair value on a non-recurring basis. We did not have any material items that are measured at fair value on a non-recurring basis for the years ended December 31, 2012, 2013 and 2014, except goodwill calculated based on Level 3 inputs, as more fully disclosed in Note 2.g.
t.Available-for-sale and Trading Securities
We have one trust that holds marketable securities. Marketable securities are classified as available-for-sale or trading. As of December 31, 2013 and 2014, the fair value of the money market and mutual funds included in this trust amounted to $13,386 and $13,172 respectively, and were included in prepaid expenses and other in the accompanying Consolidated Balance Sheets. We classified these marketable securities included in the trust as trading, and included in other expense (income), net in the accompanying Consolidated Statements of Operations are realized and unrealized net gains (losses) of $1,292, $2,283 and $1,112 for the years ended December 31, 2012, 2013 and 2014, respectively, related to these marketable securities.
u.Investments
As of December 31, 2014, we had a 4% investment in Crossroads Systems, Inc. Its carrying value as of December 31, 2013 and 2014 was $1,404 and $1,457, respectively, and is included in other assets in the accompanying Consolidated Balance Sheets. This investment, which is publicly traded, is carried at fair value with corresponding changes to fair value recorded in accumulated other comprehensive items, net.
v.Accumulated Other Comprehensive Items, Net
The changes in accumulated other comprehensive items, net for the years ended December 31, 2013 and 2014 is as follows:

x.New Accounting Pronouncements
In April 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360) (“ASU 2014-08”). ASU 2014-08 changes the criteria for a disposal to qualify as a discontinued operation and requires additional disclosures of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation. ASU 2014-08 is effective for annual periods beginning on or after December 15, 2014. Under this guidance, we expect fewer dispositions to qualify as discontinued operations. Early adoption is permitted, but only for disposals that have not been reported in the financial statements previously issued. We adopted ASU 2014-08 effective April 1, 2014.
In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”). ASU 2014-09 provides additional guidance for management to reassess revenue recognition as it relates to: (1) transfer of control, (2) variable consideration, (3) allocation of transaction price based on relative standalone selling price, (3) licenses, (4) time value of money and (5) contract costs. Further disclosures will be required to provide a better understanding of revenue that has been recognized and revenue that is expected to be recognized in the future from existing contracts. ASU 2014-09 is effective for us on January 1, 2017, with no early adoption permitted. We are currently evaluating the impact ASU 2014-09 will have on our consolidated financial statements.
In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements Going Concern (Subtopic 205-40) (“ASU 2014- 15”). ASU 2014-15 requires management to assess an entity’s ability to continue as a going concern by incorporating and expanding upon certain principles of current United States auditing standards. Specifically, the amendments (1) provide a definition of the term “substantial doubt”, (2) require an evaluation every reporting period, including interim periods, (3) provide principles for considering the mitigating effect of management’s plans, (4) require certain disclosures when substantial doubt is alleviated as a result of consideration of management’s plans, (5) require an express statement and other disclosures when substantial doubt is still present, and (6) require an assessment for a period of one year after the date that the financial statements are issued (or available to be issued). ASU 2014-15 is effective for us on January 1, 2017, with early adoption permitted. We do not believe that this pronouncement will have an impact on our consolidated financial statements.
In February 2015, the FASB issued ASU No. 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis (“ASU 2015- 02”). ASU 2015-02 affects reporting entities that are required to evaluate whether they should consolidate certain legal entities. ASU 2015-02 is effective for us on January 1, 2016, with early adoption permitted. We do not believe that this pronouncement will have an impact on our consolidated financial statements.
y.Immaterial Restatement
During the second quarter of 2014, we identified contract billing inaccuracies arising from a single location which occurred over numerous years that resulted in an overstatement of our prior years’ reported revenue by $10,000 in the aggregate. Of this amount, $1,300 relates to the year ended December 31, 2013, $1,300 relates to the year ended December 31, 2012 and the remaining $7,400 relates to the periods prior to December 31, 2011. We have determined that no prior period financial statement was materially misstated as a result of these billing inaccuracies. As a result, we have restated beginning retained earnings as of December 31, 2011 for the cumulative impact of these billing inaccuracies, net of tax, prior to December 31, 2011 in the amount of $4,514.
Additionally, we have restated the following: (1) our 2013 Consolidated Balance Sheet, (2) our 2012 and 2013 Consolidated Statements of Operations, (3) our 2012 and 2013 Consolidated Statements of Comprehensive Income (Loss), (4) our 2012 and 2013 Consolidated Statements of Equity and (5) our 2012 and 2013 Consolidated Statements of Cash Flows to reflect the impact of these billing inaccuracies in those particular periods. There was no change to the following lines of the Consolidated Statement of Cash Flows for the years ended December 31, 2012 and 2013: (1) cash flows from operating activities, (2) cash flows from investing activities and (3) cash flows from financing activities. Also, we restated the 2013 quarterly data presented in Note 8.
The following table sets forth the effect of the immaterial restatement to certain line items of our Consolidated Statements of Operations for the years ended December 31, 2012 and 2013:

Derivative Instruments and Hedging Activities
Derivative Instruments and Hedging Activities
	3. Derivative Instruments and Hedging Activities
	We have entered into a number of separate forward contracts to hedge our exposures in Euros, British pounds sterling and Australian dollars. As of December 31, 2014, we had outstanding forward contracts to purchase 206,000 Euros and sell $252,745 United States dollars to hedge our intercompany exposures with our European operations. At the maturity of the forward contracts, we may enter into new forward contracts to hedge movements in the underlying currencies. At the time of settlement, we either pay or receive the net settlement amount from the forward contract and recognize this amount in other expense (income), net in the Consolidated Statements of Operations as a realized foreign exchange gain or loss. At the end of each month, we mark the outstanding forward contracts to market and record an unrealized foreign exchange gain or loss for the mark-to-market valuation. We have not designated forward contracts as hedges. During the years ended December 31, 2012, 2013 and 2014, there was $9,116 in net cash payments, $6,954 in net cash receipts and $21,125 in net cash payments, respectively, included in cash from operating activities from continuing operations related to settlements associated with foreign currency forward contracts.
	Our policy is to record the fair value of each derivative instrument on a gross basis. The following table provides the fair value of our derivative instruments as of December 31, 2013 and 2014 and their gains and losses for the years ended December 31, 2012, 2013 and 2014:

	We have designated a portion of our 63/4% Notes as a hedge of net investment of certain of our Euro denominated subsidiaries. For the years ended December 31, 2012, 2013 and 2014, we designated on average 101,167, 106,525 and 47,730 Euros, respectively, of the 63/4% Notes as a hedge of net investment of certain of our Euro denominated subsidiaries. As a result, we recorded the following foreign exchange (losses) gains, net of tax, related to the change in fair value of such debt due to the currency translation adjustments, which is a component of accumulated other comprehensive items, net:

		-1		The capital stock or other equity interests of most of our United States subsidiaries, and up to 66% of the capital stock or other equity interests of our first-tier foreign subsidiaries, are pledged to secure these debt instruments, together with all intercompany obligations (including promissory notes) of subsidiaries owed to us or to one of our United States subsidiary guarantors. In addition, Iron Mountain Canada Operations ULC (“Canada Company”) has pledged 66% of the capital stock of its subsidiaries, and all intercompany obligations (including promissory notes) owed to or held by it, to secure the Canadian dollar subfacility under the Revolving Credit Facility (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, 2013 and 2014, 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, 2013 and 2014, 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 substantially all of its direct and indirect 100% owned United States subsidiaries (the “Guarantors”). These guarantees are joint and several obligations of the Guarantors. Canada Company, Iron Mountain Europe PLC (“IME”) and the remainder of our subsidiaries do not guarantee the Parent Notes.
		-4		Canada Company is the direct obligor on the CAD Notes, which are fully and unconditionally guaranteed, on a senior basis, by IMI and the Guarantors. These guarantees are joint and several obligations of IMI and the Guarantors. See Note 5 to Notes to Consolidated Financial Statements.
		-5		IME is the direct obligor on the GBP Notes, which are fully and unconditionally guaranteed, on a senior basis, by IMI and the Guarantors. These guarantees are joint and several obligations of IMI and the Guarantors. See Note 5 to Notes to Consolidated Financial Statements.
		-6		Includes (a) real estate mortgages of $3,704 and $5,107 as of December 31, 2013 and 2014, respectively, which bear interest at approximately 4.5% and are payable in various installments through 2021, (b) capital lease obligations of $255,124 and $241,866 as of December 31, 2013 and 2014, respectively, which bear a weighted average interest rate of 5.8% at both December 31, 2013 and 2014, and (c) other various notes and other obligations, which were assumed by us as a result of certain acquisitions, of $39,619 and $73,729 as of December 31, 2013 and 2014, respectively, and bear a weighted average interest rate of 14.3% and 11.5% as of December 31, 2013 and 2014, respectively. We believe the fair value (Level 3 of fair value hierarchy described at Note 2.s.) of this debt approximates its carrying value.
	a.Revolving Credit Facility
	On August 7, 2013, we amended our existing credit agreement. The revolving credit facilities (the “Revolving Credit Facility”) under our credit agreement, as amended (the “Credit Agreement”), allow IMI and certain of its United States and foreign subsidiaries to borrow in United States dollars and (subject to sublimits) a variety of other currencies (including Canadian dollars, British pounds sterling, Euros, Brazilian reais and Australian dollars, among other currencies) in an aggregate outstanding amount not to exceed $1,500,000. Additionally, the Credit Agreement included an option to allow us to request additional commitments of up to $500,000, in the form of term loans or through increased commitments under the Revolving Credit Facility. On September 24, 2014, we borrowed an additional $250,000 in the form of a term loan under the Credit Agreement (the “Term Loan”). Commencing on December 31, 2014, the Term Loan will begin amortizing in quarterly installments in an amount equal to $625 per quarter, with the remaining balance due on June 27, 2016. The Term Loan may be prepaid without penalty or premium, in whole or in part, at any time. The Credit Agreement continues to include an option to allow us to request additional commitments of up to $250,000, in the form of term loans or through increased commitments under the Revolving Credit Facility.
	The Credit Agreement terminates on June 27, 2016, at which point all obligations become due. IMI and the Guarantors guarantee all obligations under the Credit Agreement, and have pledged the capital stock or other equity interests of most of their United States subsidiaries, up to 66% of the capital stock or other equity interests of their first-tier foreign subsidiaries, and all intercompany obligations (including promissory notes) owed to or held by them to secure the Credit Agreement. In addition, Canada Company has pledged 66% of the capital stock of its subsidiaries, and all intercompany obligations (including promissory notes) owed to or held by it to secure the Canadian dollar subfacility under the Revolving Credit Facility. 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 0.3% to 0.5% based on certain financial ratios and fees associated with outstanding letters of credit. As of December 31, 2014, we had $883,428 and $249,375 of outstanding borrowings under the Revolving Credit Facility and the Term Loan, respectively. Of the $883,428 of outstanding borrowings under the Revolving Credit Facility, $680,150 was denominated in United States dollars, 77,200 was denominated in Canadian dollars, 64,250 was denominated in Euros and 71,600 was denominated in Australian dollars. In addition, we also had various outstanding letters of credit totaling $10,403. The remaining amount available for borrowing under the Revolving Credit Facility as of December 31, 2014, 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 $606,169 (which amount represents the maximum availability as of such date). The average interest rate in effect under the Credit Agreement was 2.7% as of December 31, 2014. The average interest rate in effect under the Revolving Credit Facility was 2.8% and ranged from 2.3% to 5.1% as of December 31, 2014 and the interest rate in effect under the Term Loan as of December 31, 2014 was 2.4%. For the years ended December 31, 2012, 2013 and 2014, we recorded commitment fees and letter of credit fees of $2,306, $3,167 and $3,322, respectively, based on the unused balances under our revolving credit facilities and outstanding letters of credit. We recorded a charge of $5,544 to other expense (income), net in the third quarter of 2013 related to an amendment of our revolving credit and term loan facilities, representing a write-off of deferred financing costs.
	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. IMI’s Credit Agreement net total lease adjusted leverage ratio was 5.0 and 5.4 as of December 31, 2013 and 2014, respectively, compared to a maximum allowable ratio of 6.5, and its net secured debt lease adjusted leverage ratio was 2.2 and 2.6 as of December 31, 2013 and 2014, respectively, compared to a maximum allowable ratio of 4.0. IMI’s bond leverage ratio (which is not lease adjusted), per the indentures, was 5.1 and 5.7 as of December 31, 2013 and 2014, respectively, compared to a maximum allowable ratio of 6.5. IMI’s Credit Agreement fixed charge coverage ratio was 2.5 at both December 31, 2013 and 2014 compared to a minimum allowable ratio of 1.5 under the Credit Agreement. Noncompliance with these leverage and fixed charge coverage ratios would have a material adverse effect on our financial condition and liquidity.
	b.Notes Issued under Indentures
	As of December 31, 2014, we had seven series of senior subordinated or senior notes issued under various indentures, five of which are direct obligations of the parent company, IMI; one (the CAD Notes) is a direct obligation of Canada Company; one (the GBP Notes) is a direct obligation of IME; and all are subordinated to debt outstanding under the Credit Agreement, except the 6% Notes, the CAD Notes and the GBP Notes which are pari passu with the Credit Agreement:
		"		255,000 Euro principal amount of notes maturing on October 15, 2018 and bearing interest at a rate of 63/4% per annum, payable semi- annually in arrears on April 15 and October 15;
		"		$400,000 principal amount of notes maturing on October 1, 2019 and bearing interest at a rate of 73/4% per annum, payable semi-annually in arrears on April 1 and October 1;
		"		$106,250 principal amount of notes maturing on August 15, 2021 and bearing interest at a rate of 83/8% per annum, payable semi-annually in arrears on February 15 and August 15;

		"		$1,000,000 principal amount of notes maturing on August 15, 2024 and bearing interest at a rate of 53/4% per annum, payable semi-annually in arrears on February 15 and August 15.
	The Parent Notes, the CAD Notes and the GBP Notes are fully and unconditionally guaranteed, on a senior or senior subordinated basis, as the case may be, by the Guarantors. These guarantees are joint and several obligations of the Guarantors. The remainder of our subsidiaries do not guarantee the Parent Notes, the CAD Notes or the GBP Notes. Additionally, IMI guarantees the CAD Notes and the GBP Notes. Canada Company and IME do not guarantee the Parent Notes.
	In August 2012, we redeemed (1) the $320,000 aggregate principal amount outstanding of the 65/8% Senior Subordinated Notes due 2016 at 100% of par, plus accrued and unpaid interest, and (2) the $200,000 aggregate principal amount outstanding of the 83/4% Senior Subordinated Notes due 2018 at 102.9% of par, plus accrued and unpaid interest. We recorded a charge to other expense (income), net of $10,628 related to the early extinguishment of this debt in the third quarter of 2012. This charge consists of the call premium, original issue discounts and deferred financing costs related to this debt.
	In August 2013, IMI completed an underwritten public offering of $600,000 in aggregate principal amount of 6% Notes, and Canada Company completed an underwritten public offering of 200,000 CAD in aggregate principal amount of the CAD Notes, both of which were issued at 100% of par (together, the “August 2013 Offerings”). The net proceeds to IMI and Canada Company of $782,307, after paying the underwriters’ discounts and commissions, were used to redeem (1) all of the outstanding 71/2% CAD Senior Subordinated Notes due 2017, (2) all of the outstanding 8% Senior Subordinated Notes due 2018, (3) all of the outstanding 8% Senior Subordinated Notes due 2020, and (4) $137,500 in principal amount of the 83/8% Notes. The remaining net proceeds were used to repay indebtedness under our Revolving Credit Facility. We recorded a charge to other expense (income), net of $38,118 in the third quarter of 2013 related to the early extinguishment of this debt. This charge consists of call and tender premiums, original issue discounts and deferred financing costs related to this debt.
	In January 2014, we redeemed the 150,000 British pounds sterling (approximately $248,000) in aggregate principal amount of the 71/4% Notes at 100% of par, plus accrued and unpaid interest, utilizing borrowings under our 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 our Revolving Credit Facility and for general corporate purposes.
	In December 2014, we redeemed $306,000 aggregate principal outstanding of our 83/8% Notes at 104.188% of par, plus accrued and unpaid interest, utilizing borrowings under our 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 deferred financing costs related to this debt.
	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:

Selected Consolidated Financial Statements of Parent, Guarantors, Canada Company and Non-Guarantors	12 Months Ended

Selected Consolidated Financial Statements of Parent, Guarantors, Canada Company and Non-Guarantors
Selected Consolidated Financial Statements of Parent, Guarantors, Canada Company and Non-Guarantors
	5. 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, 2013 and 2014 and for the years ended December 31, 2012, 2013 and 2014 and are prepared on the same basis as the consolidated financial statements.
	The Parent Notes, CAD Notes and GBP Notes are guaranteed by the subsidiaries referred to below as the Guarantors. These subsidiaries are 100% owned by IMI. The guarantees are full and unconditional, as well as joint and several.
	Additionally, IMI and the Guarantors guarantee the CAD Notes, which were issued by Canada Company, and the GBP Notes, which were issued by IME. Canada Company and IME do not guarantee the Parent Notes. The subsidiaries that do not guarantee the Parent Notes, the CAD Notes and the GBP Notes, including IME 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 balance sheets and equity in the earnings (losses) of subsidiaries, net of tax in the below statements of operations with respect to the relevant Parent, Guarantors, Canada Company, Non-Guarantors and Eliminations columns also would change.

	6. Acquisitions
	We account for acquisitions using the acquisition method of accounting, and, accordingly, the assets and liabilities acquired were recorded at their estimated fair values and the results of operations for each acquisition have been included in our consolidated results from their respective acquisition dates. Cash consideration for our various acquisitions was primarily provided through borrowings under our credit facilities and cash equivalents on-hand. The unaudited pro forma results of operations (including revenue and earnings) for the current and prior periods are not presented due to the insignificant impact of the 2012, 2013 and 2014 acquisitions on our consolidated results of operations. Noteworthy acquisitions are as follows:
	In April 2012, in order to enhance our existing operations in Brazil, we acquired the stock of Grupo Store, a storage rental and records management and data protection business in Brazil with locations in Sao Paulo, Rio de Janeiro, Porto Alegre and Recife, for a purchase price of approximately $79,000 ($75,000, net of cash acquired). Included in the purchase price is approximately $8,000 held in escrow to secure a working capital adjustment and the indemnification obligations of the former owners of the business (“Sellers”) to IMI. In 2013, approximately $1,500 of the escrow funds were released to the Sellers in connection with the final working capital adjustment. Unless paid to us in accordance with the terms of the agreement, all amounts remaining in escrow after any indemnification payments are paid to the Sellers in four annual installments, commencing in April 2014.
	In May 2012, we acquired a controlling interest of our joint venture in Switzerland (Sispace AG), which provides storage rental and records and information management services, in a stock transaction for a cash purchase price of approximately $21,600. The carrying value of the 15% interest that we previously held and accounted for under the equity method of accounting amounted to approximately $1,700 as of the date of acquisition, and the fair value on the date of the acquisition of such interest was approximately $2,700. This resulted in a gain being recorded to other income (expense), net of approximately $1,000 in the second quarter of 2012. The fair value of our previously held equity interest was derived by reducing the total estimated consideration for the controlling interest purchased by 30%, which represents management’s estimate of the control premium paid, in order to derive the fair value of $2,700 for the 15% noncontrolling equity interest which we previously held. We determined the 30% control premium was appropriate after considering the size and location of the business acquired, the potential future profits expected to be generated by the Swiss entity and other publicly available market data.
	In May 2013, in order to enhance our existing operations in the United States, we acquired a storage rental and records management business in Texas with locations in Michigan, Texas and Florida, in a cash transaction for a purchase price of approximately $25,000.
	In June 2013, in order to enhance our existing operations in Brazil, we acquired the stock of Archivum Comercial Ltda. and AMG Comercial Ltda., storage rental and records management businesses in Sao Paulo, Brazil, in a single transaction for an aggregate purchase price of approximately $29,000. Included in the purchase price is approximately $2,900 held in escrow to secure a post-closing working capital adjustment and the indemnification obligations of the former owners of the businesses to us, to be released in annual installments through 2017.
	In September 2013, in order to enhance our existing operations in Latin America, we acquired certain entities with operations in Colombia and Peru. We acquired the stock of G4S Secure Data Solutions Colombia S.A.S. and G4S Document Delivery S.A.S (collectively, “G4S”). G4S, a storage rental and records management business with operations in Bogota, Cali, Medellin and Pereira, Colombia, was acquired in a single transaction for an aggregate purchase price of approximately $54,000. We also acquired the stock of File Service S.A., a storage rental and records management business in Peru, for a purchase price of approximately $16,000.
	In October 2013, in order to enhance our existing operations in the United States, we acquired Cornerstone Records Management, LLC and its affiliates, a national, full solution records and information-management company, in a cash transaction for a purchase price of approximately $191,000. Included in the purchase price is approximately $9,000 held in escrow to secure indemnification obligations and certain working capital adjustments.
	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 February 2014, in order to enhance our existing operations in Turkey, we acquired the stock of RM Arşiv Yönetim Hizmetleri Ticaret Anonim Şirketi, a storage rental and records management business with operations in Turkey, for approximately $21,200, of which $16,750 was paid in the first quarter of 2014, with the remainder paid in the first quarter of 2015.
	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. The purchase price includes $5,425 held in escrow to secure indemnification obligations of the former owners of the business to us.
	In December 2014, in order to enhance our North American records management operations, we acquired the stock of Canadian-based Securit Records Management for approximately $29,500. Included in the purchase price is approximately $1,300 held in escrow to secure indemnification obligations and certain working capital adjustments.
	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:

		-1		Included in cash paid for acquisitions in the Consolidated Statements of Cash Flows for the year ended December 31, 2013 is contingent and other payments of $(76). Included in cash paid for acquisitions in the Consolidated Statements 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 previous years.
		-2		Consists primarily of racking structures, leasehold improvements and computer hardware and software.
		-3		The weighted average lives of customer relationship intangible assets associated with acquisitions in 2012, 2013 and 2014 was 17 years, 22 years and 17 years, respectively.
		-4		Consists primarily of accounts payable, accrued expenses, notes payable, deferred revenue and deferred income taxes.
	Allocations of the purchase price paid for certain acquisitions made in 2014 were based on estimates of the fair value of net assets acquired and are subject to adjustment as additional information becomes available to us. We are not aware of any information that would indicate that the final purchase price allocations for these 2014 acquisitions will differ meaningfully from preliminary estimates. The purchase price allocations of these 2014 acquisitions are subject to finalization of the assessment of the fair value of intangible assets (primarily customer relationship intangible assets), property, plant and equipment (primarily racking structures), operating leases, contingencies and income taxes (primarily deferred income taxes).
	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.

	As noted previously, on June 25, 2014, we announced that we received the favorable PLRs from the IRS necessary for our conversion to a REIT. In the PLRs, the IRS addressed and favorably ruled on our assets and revenue model, including regarding our steel racking structures as real estate for REIT purposes under the Internal Revenue Code of 1986, as amended (the “Code”), our global operations and our transition plans from a C corporation to a REIT. The PLRs are subject to certain qualifications and are based upon certain representations and statements made by us. If such representations and statements are untrue or incomplete in any material respect (including as a result of a material change in relevant facts), we may not be able to rely on the PLRs. After receipt of the PLRs, our board of directors unanimously approved our conversion to a REIT for our taxable year beginning January 1, 2014.
	As a REIT, we are generally permitted to deduct from our federal taxable income the dividends we pay to our stockholders. The income represented by such dividends is not subject to federal taxation at the entity level but is taxed, if at all, at the stockholder level. The income of our domestic taxable REIT subsidiaries (“TRSs”), which hold our domestic operations that may not be REIT-compliant as currently operated and structured, is subject, as applicable, to federal and state corporate income tax. In addition, we and our subsidiaries continue to be subject to foreign income taxes in jurisdictions in which they hold assets or conduct operations, regardless of whether held or 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 specified period (generally ten years) following the REIT conversion that are attributable to “built-in” gains with respect to the assets that we owned on January 1, 2014; this built-in gains tax will also be imposed on our depreciation recapture recognized into income in 2014 and subsequent taxable years as a result of accounting method changes commenced in our pre- REIT period. If we fail to remain qualified for taxation as a REIT, we will be subject to federal income tax at regular corporate tax rates. Even if we remain qualified for taxation as a REIT, we may be subject to some federal, state, local and foreign taxes on our income and property in addition to taxes owed with respect to our TRS operations. In particular, while state income tax regimes often parallel the federal income tax regime for REITs, many states do not completely follow federal rules and some do not follow them at all.

	As of December 31, 2013, we have reclassified approximately $26,916 of long-term deferred income tax liabilities to current deferred income taxes (included within accrued expenses within current liabilities) and prepaid and other assets (included within current assets) in the accompanying Consolidated Balance Sheets related to the depreciation recapture associated with our characterization of certain racking structures as real estate rather than personal property and amortization associated with other intangible assets in conjunction with our conversion to a REIT.
	We have federal net operating loss carryforwards, which expire in 2021 through 2033, of $88,090 ($0, tax effected) at December 31, 2014 to reduce future federal taxable income, on which no federal tax benefit is expected to be realized. We have state net operating loss carryforwards, which expire in 2015 through 2033, of $74,439 ($112, tax effected) at December 31, 2014 to reduce future state taxable income, on which an insignificant state tax benefit is expected to be realized. We have assets for foreign net operating losses of $64,606, with various expiration dates (and in some cases no expiration date), subject to a valuation allowance of approximately 62%.
	Rollforward of the valuation allowance is as follows:

	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 included in the consolidated financial statements in the period in which compensation expense is recorded. The tax benefit associated with compensation expense recorded in the consolidated financial statements related to incentive stock options associated with our TRSs is recorded in the period the disqualifying disposition occurs. Incremental tax benefits (deficiencies) in excess of compensation expense recorded in the consolidated financial statements are credited (charged) directly to equity and amounted to $1,045, $2,389 and $(60) for the years ended December 31, 2012, 2013 and 2014, respectively.

Our effective tax rates for the years ended December 31, 2012, 2013 and 2014 were 38.5%, 38.9% and (43.5)%, 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; (2) tax law changes; (3) volatility in foreign exchange gains (losses); (4) the timing of the establishment and reversal of tax reserves; and (5) our ability to utilize foreign tax credits and net operating losses that we generate.
The primary reconciling items between the federal statutory rate of 35% and our overall effective tax rate for the year ended December 31, 2012 were differences in the rates of tax at which our foreign earnings are subject, including foreign exchange gains and losses in different jurisdictions with different tax rates and state income taxes (net of federal tax benefit). During the year ended December 31, 2012, foreign currency gains were recorded in lower tax jurisdictions associated with our marking-to-market of intercompany loan positions while foreign currency losses were recorded in higher tax jurisdictions associated with our marking-to-market of debt and derivative instruments, which lowered our 2012 effective tax rate by 2.2%. The primary reconciling items between the federal statutory rate of 35% and our overall effective tax rate for the year ended December 31, 2013 were the impact from the repatriation discussed below, which increased our 2013 effective tax rate by 13.1%, and state income taxes (net of federal tax benefit). These expenses were partially offset by a favorable impact provided by the recognition of certain previously unrecognized tax benefits due to expirations of statute of limitation periods and settlements with tax authorities in various jurisdictions and differences in the rates of tax at which our foreign earnings are subject, including foreign exchange gains and losses in different jurisdictions with different tax rates.
During 2013, we completed a plan to utilize both current and carryforward foreign tax credits by repatriating approximately $252,700 (approximately $65,200 of which was previously subject to United States taxes) from our foreign earnings. Due to uncertainty in our ability to fully utilize foreign tax credit carryforwards, we previously did not recognize a full benefit for such foreign tax credit carryforwards in our tax provision. As a result, we recorded an increase in our tax provision from continuing operations in the amount of $63,504 in 2013. This increase was offset by decreases of $18,753 from current year foreign tax credits and $23,301 reversal of valuation allowances related to foreign tax credit carryforwards, resulting in a net increase of $21,450 in our tax provision from continuing operations.
On September 13, 2013, the United States Department of the Treasury and the IRS released final tangible property regulations under Sections 162(a) and 263(a) of the Code regarding the deduction and capitalization of expenditures related to tangible property. In addition, proposed regulations under Section 168 of the Code regarding dispositions of tangible property have also been released. These final and proposed regulations are generally effective for our tax year beginning on January 1, 2014. Early adoption was available, and we adopted the regulations in 2013. The impact from these regulations did not have a material impact on our consolidated results of operations, cash flows and financial position.
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 primary other reconciling items between the federal statutory rate of 35% and our overall effective tax rate during the year ended December 31, 2014 was an increase of $46,356 in our tax provision from the repatriation discussed below and other net tax adjustments related to the REIT conversion, including a tax benefit of $63,333 primarily related to the dividends paid deduction. 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 following table presents a reconciliation of significant components of deferred tax assets and liabilities from December 31, 2013 to December 31, 2014:

We had not previously provided incremental federal and certain state income taxes on net tax over book outside basis differences related to the earnings of our foreign subsidiaries because our intent, prior to our conversion to a REIT, was to reinvest our current and future undistributed earnings of certain foreign subsidiaries indefinitely outside the United States. As a result of our conversion to a REIT, it is no longer our intent to indefinitely reinvest our current and future undistributed foreign earnings outside the United States, and, therefore, during 2014, we recognized an increase in our tax provision from continuing operations in the amount of $46,356, representing incremental federal and state income taxes and foreign withholding taxes on such foreign earnings. As a REIT, future repatriation of incremental undistributed earnings of our foreign subsidiaries will not be subject to federal or state income tax, with the exception of foreign withholding taxes in limited instances; however, such future repatriations will require distribution in accordance with REIT distribution rules, and any such distribution may then be taxable, as appropriate, at the stockholder level.
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 at the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement.
We have elected to recognize interest and penalties associated with uncertain tax positions as a component of the provision (benefit) for income taxes in the accompanying Consolidated Statements of Operations. We recorded an increase of $1,257, $1,459 and $1,462 for gross interest and penalties for the years ended December 31, 2012, 2013 and 2014, respectively. We had $4,874 and $5,884 accrued for the payment of interest and penalties as of December 31, 2013 and 2014, 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
2009 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. The 2011, 2012 and 2013 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 and 2008 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, 2013, we had $51,146 of reserves related to uncertain tax positions included in other long-term liabilities in the accompanying Consolidated Balance Sheet. As of December 31, 2014, we had $55,951 of reserves related to uncertain tax positions, of which $53,078 and $2,873 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 reconciliation of unrecognized tax benefits is as follows:
Gross tax contingencies—December 31, 2011		$
		31,408
Gross additions based on tax positions related to the current year		6,598
Gross additions for tax positions of prior years		3,912

Settlements		-1,099

		37,563
Gross additions based on tax positions related to the current year		5,985
Gross additions for tax positions of prior years		20,275
Gross reductions for tax positions of prior years		-1,370
Lapses of statutes		-1,312
Settlements		-9,995
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
The reversal of these reserves of $55,951 ($41,990 net of federal tax benefit) as of December 31, 2014 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 $6,560 of our unrecognized tax positions may be recognized by the end of 2015 as a result of a lapse of statute of limitations or upon closing and settling significant audits in various worldwide jurisdictions.

		-1		The change in net income (loss) attributable to Iron Mountain Incorporated in the fourth quarter of 2013 compared to the third quarter of 2013 is primarily attributable to a benefit for income taxes recorded in the fourth quarter of 2013 compared to a provision recorded in the third quarter of 2013 for a net benefit of approximately $50,200, as well as a decrease in other expenses, net of approximately $34,700 primarily as a result of debt extinguishment charges recorded in the third quarter of 2013 of approximately $43,600 that did not repeat in the fourth quarter of 2013, offset by an increase in foreign exchange transaction losses of approximately $11,000. Offsetting these benefits was a decrease in operating income of approximately $42,900. The decrease in operating income is primarily attributable to: (1) $18,700 of restructuring costs associated with our organizational realignment, (2) $11,200 of facilities costs primarily associated with facility consolidation, (3) $8,100 of other cost increases, including costs associated with recent acquisitions and executing our strategy, (4) $3,600 of increased depreciation and amortization, primarily related to business acquisitions, (5) $3,000 in sales, marketing and account management costs within our North American Records and Information Management Business and North American Data Management Business segments (primarily associated with sales commissions), (6) $2,200 of increased bad debt expense and (7) $2,000 of charitable contributions, partially offset by a $7,100 decrease in REIT Costs (defined at Note 9) incurred in the fourth quarter compared to the third quarter of 2013.
		-2		The change in net income (loss) attributable to Iron Mountain Incorporated in the fourth quarter of 2014 compared to the third quarter of 2014 is primarily attributable to a decrease in the provision for income taxes recorded in the fourth quarter of 2014 compared to the third quarter of 2014 of approximately $54,000. The decrease in the income tax provision was offset by a decrease in operating income of approximately $13,600, a debt extinguishment charge recorded in the fourth quarter of 2014 of approximately $16,500 and an increase in interest expense of $9,800. The decrease in operating income is attributable to a $8,300 increase in selling, general and administrative expenses, primarily due to higher professional fees and charitable contributions, as well as a $4,700 decrease in revenue, primarily due to unfavorable changes in foreign exchange rates, in the fourth quarter compared to the third quarter.

Segment Information
Segment Information
	9. Segment Information
	As a result of a realignment in senior management reporting structure during the first quarter of 2015, we modified our internal financial reporting to better align internal reporting with how we manage our business. These modifications resulted in the separation of our former International Business segment into two unique reportable operating segments, which we refer to as (1) Western European Business segment and (2) Other International Business segment. Additionally, during the first quarter of 2015, we reassessed the nature of certain costs which were previously being allocated to the North American Records and Information Management Business and North American Data Management Business segments. As a result of this reassessment, we determined that certain product management functions, which were previously being performed to solely benefit our North American operating segments, are now being performed in a manner that benefits the enterprise as a whole. Accordingly, the costs associated with these product management functions are now included within the Corporate and Other Business segment. Previously reported segment information has been restated.
	Our five reportable operating segments are described as follows:
		·		North American Records and Information Management Business—storage and information management services throughout the United States and Canada, including the storage of paper documents, as well as other media such as microfilm and microfiche, master audio and videotapes, film, X-rays and blueprints, including healthcare information services, vital records services, service and courier operations, and the collection, handling and disposal of sensitive documents for corporate customers (“Records Management”); information destruction services (“Destruction”); DMS; Fulfillment Services; and Intellectual Property Management.
		·		North American Data Management Business—storage and rotation of backup computer media as part of corporate disaster recovery plans throughout the United States and Canada, including service and courier operations (“Data Protection & Recovery”); server and computer backup services; digital content repository systems to house, distribute, and archive key media assets; and storage, safeguarding and electronic or physical delivery of physical media of all types, primarily for entertainment and media industry clients.
		·		Western European Business—Records Management, Data Protection & Recovery and DMS throughout the United Kingdom, Ireland, Norway, Austria, Belgium, France, Germany, Netherlands, Spain and Switzerland. Until December 2014, our Western European Business segment offered Destruction in the United Kingdom and Ireland.
		·		Other International Business—storage and information management services throughout the remaining European countries in which we operate, Latin America and Asia Pacific, including Records Management, Data Protection & Recovery and DMS. Our European operations included within the Other International Business segment provide Records Management, Data Protection & Recovery and DMS. Our Latin America operations provide Records Management, Data Protection & Recovery, Destruction and DMS throughout Argentina, Brazil, Chile, Colombia, Mexico and Peru. Our Asia Pacific operations provide Records Management, Data Protection & Recovery and DMS throughout Australia, with Records Management and Data Protection & Recovery also provided in certain cities in India, Singapore, Hong Kong-SAR and China. Until December 2014, our Other International Business segment offered Destruction in Australia.
		·		Corporate and Other Business —consists of our data center business in the United States, the primary product offering of our Emerging Businesses segment, as well as costs related to executive and staff functions, including finance, human resources and information technology, which benefit the enterprise as a whole. These costs are primarily related to the general management of these functions on a corporate level and the design and development of programs, policies and procedures that are then implemented in the individual segments, with each segment bearing its own cost of implementation. Our Corporate and Other Business segment also includes stock-based employee compensation expense associated with all Employee Stock-Based Awards.

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

Commitments and Contingencies
Commitments and Contingencies
	10. 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 $250,986, $244,390 and $255,193 for the years ended December 31, 2012, 2013 and 2014, 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	Sublease	Capital
		Payment	Income	Leases
	2015	$	$	$
		233,428	-5,657	52,531

	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, 2013 and 2014 there were $32,850 and $33,381, respectively, of self-insurance accruals reflected in accrued expenses of 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 $4,500 over the next several years, of which certain amounts would be covered by insurance or indemnity arrangements.
	d.Government Contract Billing Matter
	Since October 2001, we have provided services to the United States Government under several General Services Administration (“GSA”) multiple award schedule contracts (the “Schedules”). The Schedules contain a price reductions clause (“Price Reductions Clause”) that requires us to offer to reduce the prices billed under the Schedules to correspond to the prices billed to certain benchmark commercial customers. In 2011, we initiated an internal review covering the contract period commencing in October 2006, and we discovered potential non-compliance with the Price Reductions Clause. We voluntarily disclosed the potential non-compliance for that period to the GSA and its Office of Inspector General (“OIG”) in June 2011.
	In April 2012, the United States Government sent us a subpoena seeking information that substantially overlapped with the subjects that were covered by the voluntary disclosure process that we initiated with the GSA and OIG in June 2011, except that the subpoena sought information dating back to 2000, and sought information about non-GSA federal and state and local customers. In June 2014, we learned that the government subpoena and investigation were the result of a pending, sealed qui tam lawsuit brought against us on behalf of the United States and the State of California. In December 2014, we settled the lawsuit. As a result of the settlement, we paid the United States Government and the State of California $44,500 and $1,250, respectively, in the fourth quarter of 2014. There was no material impact to our consolidated statement of operations in 2014 as a result of the settlement as we had previously accrued and maintained a deferred revenue liability related to this matter.
	e.Commonwealth of Massachusetts Assessment
	During the third quarter of 2012, we applied for an abatement of assessments from the Commonwealth of Massachusetts. The assessments, issued in the second quarter of 2012, related to a corporate excise audit of the 2004 through 2006 tax years in the aggregate amount of $8,191, including tax, interest and penalties through the assessment date. The applications for abatement were denied during the third quarter of 2012. On October 19, 2012 we filed petitions with the Massachusetts Appellate Tax Board challenging the assessments. In addition, during the second quarter of 2013, Massachusetts assessed tax for the 2007 and 2008 tax years in the aggregate amount of $4,120, including tax, interest and penalties through the assessment date. The assessment is for issues consistent with those assessed in the earlier years. In the third quarter of 2013, we filed an application for abatement for the 2007 and 2008 tax years, which Massachusetts denied on October 15, 2013. On December 13, 2013, we filed a petition with the Massachusetts Appellate Tax Board to challenge the assessment for the 2007 and 2008 tax years. In February 2015, we reached a settlement agreement with the Commonwealth of Massachusetts, under which we paid $6,000 to settle the assessments related to the 2004 through 2008 tax years. Additionally, following a corporate excise audit for the 2009 through 2011 tax years, Massachusetts has issued Notices of Intention to Assess dated December 27, 2014 which set forth proposed corporate excise assessments in the aggregate amount of $1,503, including tax, interest and penalties. We intend to defend this matter vigorously at the Massachusetts Appellate Tax Board.
	f.Italy Fire
	On November 4, 2011, we experienced a fire at a facility we leased in Aprilia, Italy. The facility primarily stored archival and inactive business records for local area businesses. Despite quick response by local fire authorities, damage to the building was extensive, and the building and its contents were a total loss. Although our warehouse legal liability insurer has reserved its rights to contest coverage related to certain types of potential claims, we believe we carry adequate insurance. We have been sued by four customers, of which three of those matters have been settled. We have also received correspondence from other customers, under various theories of liabilities. We deny any liability with respect to the fire and we have referred these claims to our warehouse legal liability insurer for an appropriate response. We do not expect that this event will have a material impact on our consolidated financial condition, results of operations or cash flows. As discussed in Note 14, we sold our Italian operations on April 27, 2012, and we indemnified the buyers related to certain obligations and contingencies associated with the fire.
	Our policy related to business interruption insurance recoveries is to record gains within other (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. As a result of the sale of the Italian operations, statements of operations and cash flows related to the fire are reflected as discontinued operations.
	g.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.

	Paul F. Deninger, one of our directors, is a senior managing director at Evercore Group L.L.C. (“Evercore”). 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 exchange for an aggregate fee of up to $3,000. 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 years ended December 31, 2013 and 2014, we have incurred fees associated with the Evercore Engagement, including fees associated with the amendment of our Credit Agreement in August 2013 and discounts and commissions attributable to Evercore’s participation as one of the underwriters in the August 2013 Offerings, as well as monthly retention fees, of $2,750 and $250, respectively.

	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 February 2010, our board of directors adopted a dividend policy under which we have paid, and in the future intend to pay, quarterly cash dividends on our common stock. Declaration and payment of future quarterly dividends is at the discretion of our board of directors. In 2013 and 2014, our board of directors declared the following dividends:
	Declaration Date		Dividend		Record Date	Total	Payment

	During the years ended December 31, 2012, 2013 and 2014, we declared distributions to our stockholders of $886,896, $206,365 and $1,048,905, respectively. These distributions represent approximately $5.12 per share, $1.08 per share and $5.37 per share for the years ended December 31, 2012, 2013 and 2014, respectively, based on the weighted average number of common shares outstanding during each respective year. For each of 2012 and 2014, total amounts distributed included Special Distributions (as described above) of $700,000, or $4.07 and $3.61 per share, respectively, associated with the Company’s conversion to a REIT.
	For federal income tax purposes, distributions to our stockholders are generally treated as nonqualified ordinary dividends, qualified ordinary dividends or return of capital. The IRS 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, 2012, 2013 and 2014, the dividends we paid on our common shares were classified as follows:
			Year Ended December 31,
			2012		2013	2014
	Nonqualified ordinary dividends		0.0%		0.0%	26.4%
	Qualified ordinary dividends		100.0%		100.0%	56.4%
	Return of capital		0.0%		0.0%	17.2%
			100.0%		100.0%	100.0%
	In December 2013, our board of directors approved, and we entered into, a REIT Status Protection Rights Agreement (the “Rights Agreement”) which provided for a dividend of one preferred stock purchase right (a “Right”) for each share of our common stock outstanding on December 20, 2013. On November 18, 2014, we entered into the First Amendment to the Rights Agreement to extend the expiration of the Rights Agreement from December 9, 2014 to February 28, 2015. On January 20, 2015, in connection with the merger with our predecessor, the Rights Agreement was terminated.

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 as discontinued operations 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.

	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, including $1,500 being held in escrow. The assets sold primarily consisted of customer contracts and certain long-lived assets. We have concluded that this divestiture is not a discontinued operation under the guidance in ASU 2014-08 described in Note 2.x. and, therefore, have 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 in 2014 represent less than 1% of our consolidated revenues. Approximately $7,750 of goodwill was allocated to the International Shredding Operations, utilizing a relative fair value approach. 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.

	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)

	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, 2012, 2013 and 2014, we capitalized $26,755, $39,487 and $19,419 of costs, respectively, associated with the development of internal use computer software projects. Capitalization begins when the design stage of the application has been completed and it is probable that the project will be completed and used to perform the function intended. Capitalization ends when the asset is ready for its intended use. Depreciation begins when the software is placed in service. Computer software costs that are capitalized are periodically evaluated for impairment.
	We 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:

	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 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:

Goodwill and Other Intangible Assets
	g.Goodwill and Other Intangible Assets
	Goodwill and intangible assets with indefinite lives are not amortized but are reviewed annually for impairment or more frequently if impairment indicators arise. Other than goodwill, we currently have no intangible assets that have indefinite lives and which are not amortized. Separable intangible assets that are not deemed to have indefinite lives are amortized over their useful lives. We annually, or more frequently if events or circumstances warrant, assess whether a change in the lives over which our intangible assets are amortized is necessary.
	We have selected October 1 as our annual goodwill impairment review date. We performed our annual goodwill impairment review as of October 1, 2012, 2013 and 2014 and concluded that goodwill was not impaired as of those dates. As of December 31, 2014, no factors were identified that would alter our October 1, 2014 goodwill assessment. In making this assessment, we relied on a number of factors including operating results, business plans, anticipated future cash flows, transactions and marketplace data. There are inherent uncertainties related to these factors and our judgment in applying them to the analysis of goodwill impairment. When changes occur in the composition of one or more reporting units, the goodwill is reassigned to the reporting units affected based on their relative fair values.
	Our reporting units at which level we performed our goodwill impairment analysis as of October 1, 2013 were as follows: (1) North America; (2) United Kingdom, Ireland, Norway, Belgium, France, Germany, Netherlands and Spain (“Western Europe”); (3) the remaining countries in Europe in which we operate, excluding Russia and Ukraine (“Emerging Markets”); (4) Latin America; (5) Australia, China, Hong Kong and Singapore (“Asia Pacific”); and (6) India, Russia and Ukraine (“Emerging Market Joint Ventures”). The carrying value of goodwill, net for each of these reporting units as of December 31, 2013 is as follows:

			1,849,440
	Western Europe		375,954

		-1		As of December 31, 2013, the goodwill associated with our operations in Austria and Switzerland was included in the Emerging Markets reporting unit. Beginning January 1, 2014, the goodwill associated with our operations in Austria and Switzerland is included in the New Western Europe reporting unit (defined below).
	Beginning January 1, 2014, as a result of the changes in our reportable operating segments associated with our 2014 reorganization, we had four reportable operating segments: (1) North American Records and Information Management Business segment, (2) North American Data Management Business segment, (3) the former International Business segment and (4) Corporate and Other Business segment. The North American Records and Information Management Business segment includes the following three reporting units: (1) North American Records and Information Management; (2) Intellectual Property Management; and (3) Fulfillment Services. The North American Data Management Business segment is a separate reporting unit. The Emerging Businesses reporting unit, which primarily relates to our data center business in the United States, is a component of the Corporate and Other Business segment. Additionally, the former International Business segment consists of the following seven reporting units: (1) United Kingdom, Ireland, Norway, Austria, Belgium, France, Germany, Netherlands, Spain and Switzerland (“New Western Europe”); (2) the remaining countries in Europe in which we operate, excluding Russia, Ukraine and Denmark (“New Emerging Markets”); (3) Latin America; (4) Australia and Singapore; (5) China and Hong Kong (“Greater China”); (6) India; and (7) Russia, Ukraine and Denmark. We have reassigned goodwill associated with the reporting units impacted by the 2014 reorganization among the new reporting units on a relative fair value basis. The fair value of each of our new reporting units was determined based on the application of a combined weighted average approach of fair value multiples of revenue and earnings and discounted cash flow techniques.
	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, we performed an interim goodwill impairment test as of January 1, 2014 on the basis of these new reporting units during the first quarter of 2014. We concluded that the goodwill for each of our new reporting units was not impaired as of such date. The carrying value of goodwill, net for each of these reporting units as of December 31, 2014 is as follows:

	As a result of a realignment in senior management reporting structure during the first quarter of 2015, we modified our internal financial reporting to better align internal reporting with how we manage our business. These modifications resulted in the separation of our former International Business segment into two unique reportable operating segments, which we refer to as (1) Western European Business segment and (2) Other International Business segment. See Note 9 for a description of our reportable operating segments.
	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, discount 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, 2013 and 2014 is as follows:

Revenues
	l.Revenues
	Our revenues consist of storage rental revenues as well as service revenues and are reflected net of sales and value added taxes. Storage rental revenues, which are considered a key driver of financial performance for the storage and information management services industry, consist primarily of recurring periodic rental charges related to the storage of materials or data (generally on a per unit basis). Service revenues include charges for related service activities, which include: (1) the handling of records, including the addition of new records, temporary removal of records from storage, refiling of removed records and the destruction of records; (2) courier operations, consisting primarily of the pickup and delivery of records upon customer request; (3) secure shredding of sensitive documents and the related sale of recycled paper, the price of which can fluctuate from period to period; (4) other services, including the scanning, imaging and document conversion services of active and inactive records, or Document Management Solutions (“DMS”), which relate to physical and digital records, and project revenues; (5) customer termination and permanent withdrawal fees; (6) data restoration projects; (7) special project work; (8) the storage, assembly, and detailed reporting of customer marketing literature and delivery to sales offices, trade shows and prospective customers’ sites based on current and prospective customer orders (“Fulfillment Services”); (9) consulting services; and (10) technology escrow services that protect and manage source code (“Intellectual Property Management”) and other technology services and product sales (including specially designed storage containers and related supplies).
	We recognize revenue when the following criteria are met: persuasive evidence of an arrangement exists, services have been rendered, the sales price is fixed or determinable and collectability of the resulting receivable is reasonably assured. Storage rental and service revenues are recognized in the month the respective storage rental or service is provided, and customers are generally billed on a monthly basis on contractually agreed-upon terms. Amounts related to future storage rental or prepaid service contracts for customers where storage rental fees or services are billed in advance are accounted for as deferred revenue and recognized ratably over the period the applicable storage rental or service is provided or performed. Revenues from the sales of products, which are included as a component of service revenues, are recognized when products are shipped and title has passed to the customer. Revenues from the sales of products have historically not been significant.
Stock-Based Compensation
	n.Stock-Based Compensation
	We record stock-based compensation expense, utilizing the straight-line method, for the cost of stock options, restricted stock, restricted stock units (“RSUs”), performance units (“PUs”) and shares of stock issued under our employee stock purchase plan (“ESPP”) (together, “Employee Stock-Based Awards”).
	Stock-based compensation expense for Employee Stock-Based Awards included in the accompanying Consolidated Statements of Operations for the years ended December 31, 2012, 2013 and 2014 was $30,360 ($23,437 after tax or $0.14 per basic and $0.13 per diluted share), $30,354 ($22,085 after tax or $0.12 per basic and $0.11 per diluted share) and $29,624 ($21,886 after tax or $0.11 per basic and diluted share), respectively.
	Stock-based compensation expense for Employee Stock-Based Awards included in the accompanying Consolidated Statements of Operations related to continuing operations is as follows:
			Year Ended December 31,
			2012		2013	2014
	Cost of sales (excluding depreciation and amortization)		$		$	$
			1,392		293	680
	Selling, general and administrative expenses		28,968		30,061	28,944
	Total stock-based compensation		$		$	$
			30,360		30,354	29,624
	The benefits associated with the tax deductions in excess of recognized compensation cost are required to be reported as financing activities in the accompanying Consolidated Statements of Cash Flows. This requirement reduces reported operating cash flows and increases reported financing cash flows. As a result, net financing cash flows from continuing operations included $1,045, $2,389 and $(60) for the years ended December 31, 2012, 2013 and 2014, respectively, from the benefits (deficiency) of tax deductions compared to recognized compensation cost. The tax benefit of any resulting excess tax deduction increases the Additional Paid-in Capital (“APIC”) pool. Any resulting tax deficiency is deducted from the APIC pool.
	Stock Options
	Under our various stock option plans, options are generally granted with exercise prices equal to the market price of the stock on the date of grant; however, in certain limited instances, options are granted at prices greater than the market price of the stock on the date of grant. The majority of our options become exercisable ratably over a period of five years from the date of grant and generally have a contractual life of ten years from the date of grant, unless the holder’s employment is terminated sooner. Certain of the options we issue become exercisable ratably over a period of ten years from the date of grant and have a contractual life of 12 years from the date of grant, unless the holder’s employment is terminated sooner. As of December 31, 2014, ten-year vesting options represented 8.0% of total outstanding options. Certain of the options we issue become exercisable ratably over a period of three years from the date of grant and have a contractual life of ten years from the date of grant, unless the holder’s employment is terminated sooner. As of December 31, 2014, three-year vesting options represented 34.3% of total outstanding options. Our non-employee directors are considered employees for purposes of our stock option plans and stock option reporting. Options granted to our non-employee directors generally become exercisable one year from the date of grant.
	Our equity compensation plans generally provide that any unvested options and other awards granted thereunder shall vest immediately if an employee is terminated by the Company, or terminates his or her 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”). Under the 2014 Plan, the total amount of shares of common stock reserved and available for issuance pursuant to awards granted under the 2014 Plan is 7,750,000. The 2014 Plan permits the Company to continue to grant awards through January 20, 2025.
	A total of 43,253,839 shares of common stock have been reserved for grants of options and other rights under our various stock incentive plans, including the 2014 Plan. The number of shares available for grant under our various stock incentive plans, not including the 2014 Plan, at December 31, 2014 was 4,581,754.
	The weighted average fair value of options granted in 2012, 2013 and 2014 was $7.00, $7.69 and $5.70 per share, respectively. These values were estimated on the date of grant using the Black-Scholes option pricing model. The following table summarizes the weighted average assumptions used for grants in the year ended December 31:
	Weighted Average Assumptions		2012		2013	2014
	Expected volatility		33.8%		33.8%	34.0%
	Risk-free interest rate		1.24%		1.13%	2.04%
	Expected dividend yield		3%		3%	4%
	Expected life		6.3 years		6.3 years	6.7 years
	Expected volatility is calculated utilizing daily historical volatility over a period that equates to the expected life of the option. The risk-free interest rate was based on the United States Treasury interest rates whose term is consistent with the expected life of the stock options. Expected dividend yield is considered in the option pricing model and represents our current annualized expected per share dividends over the current trade price of our common stock. The expected life (estimated period of time outstanding) of the stock options granted is estimated using the historical exercise behavior of employees.
	A summary of option activity for the year ended December 31, 2014 is as follows:
			Options		Weighted	Weighted	Aggregate
					Average	Average	Intrinsic
					Exercise	Remaining	Value
					Price	Contractual

	Aggregate intrinsic value of stock options exercised		$		$	$
			15,859		11,024	23,178
	Restricted Stock and Restricted Stock Units
	Under our various equity compensation plans, we may also grant restricted stock or RSUs. Our restricted stock and RSUs generally have a vesting period of between three and five years from the date of grant. 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. We accrued approximately $1,378, $1,854 and $3,698 of cash dividends on RSUs for the years ended December 31, 2012, 2013 and 2014, respectively. We paid approximately $58, $820 and $1,377 of cash dividends on RSUs for the years ended December 31, 2012, 2013 and 2014, respectively. The fair value of restricted stock and RSUs is the excess of the market price of our common stock at the date of grant over the purchase price (which is typically zero).
	A summary of restricted stock and RSU activity for the year ended December 31, 2014 is as follows:
			Restricted		Weighted-
			Stock and		Average
			RSUs		Grant-Date
					Fair Value
	Non-vested at December 31, 2013		1,435,230		$
					29.76

	Vested		-721,533		31.24
	Forfeited		-210,830		31.14
	Non-vested at December 31, 2014		1,405,569		$
					28.78
	The total fair value of restricted stock vested for each of the years ended December 31, 2012, 2013 and 2014 was $1. The total fair value of RSUs vested for the years ended December 31, 2012, 2013 and 2014 was $8,296, $16,638 and $22,535, respectively.
	Performance Units
Under our various equity compensation plans, we may also make awards of PUs. For the majority of PUs, the number of PUs earned is determined based on our performance against predefined targets of revenue or revenue growth and return on invested capital (“ROIC”). The number of PUs earned may range from 0% to 150% (for PUs granted prior to 2014) and 0% to 200% (for PUs granted in 2014) of the initial award. The number of PUs earned is determined based on our actual performance as compared to the targets at the end of either the one-year performance period (for PUs granted prior to 2014) or the three-year performance period (for PUs granted in 2014). Certain PUs granted in 2013 and 2014 will be earned based on a market condition associated with the total return on our common stock in relation to a subset of the S&P 500 rather than the revenue growth and ROIC targets noted above. The number of PUs earned based on this market condition may range from 0% to 200% of the initial award. All of our PUs will be settled in shares of our common stock and are subject to cliff vesting three years from the date of the original PU grant. For those PUs subject to a one-year performance period, employees who subsequently terminate their employment after the end of the one-year performance period and on or after attaining age 55 and completing 10 years of qualifying service (the “retirement criteria”) shall immediately and completely vest in any PUs earned based on the actual achievement against the predefined targets as discussed above (but delivery of the shares remains deferred). As a result, PUs subject to a one-year performance period are generally expensed over the shorter of (1) the vesting period, (2) achievement of the retirement criteria, which may occur as early as January 1 of the year following the year of grant or (3) a maximum of three years. Outstanding PUs accrue dividend equivalents associated with the underlying stock as we declare dividends. Dividends will generally be paid to holders of PUs in cash upon the settlement date of the associated PU and will be forfeited if the PU does not vest. We accrued approximately $369, $681 and $1,341 of cash dividends on PUs for the years ended December 31, 2012, 2013 and 2014, respectively. There were no cash dividends paid on PUs for the years ended December 31, 2012 and 2013. We paid approximately $312 of cash dividends on PUs for the year ended December 31, 2014.
In 2012, 2013 and 2014, we issued 221,781, 198,869 and 225,429 PUs, respectively. Our PUs are earned based on our performance against revenue or revenue growth and ROIC targets during their applicable performance period; therefore, we forecast the likelihood of achieving the predefined revenue, revenue growth and ROIC targets in order to calculate the expected PUs to be earned. We record a compensation charge based on either the forecasted PUs to be earned (during the applicable performance period) or the actual PUs earned (at the one-year anniversary date for PUs granted prior to 2014, and at the three-year anniversary date for PUs granted in 2014) over the vesting period for each of the awards. For the 2013 and 2014 PUs that will be earned based on a market condition, we utilized a Monte Carlo simulation to fair value these awards at the date of grant, and such fair value will be expensed over the three-year performance period. The total fair value of earned PUs that vested during the years ended December 31, 2012, 2013 and 2014 was $4,285, $2,962 and $1,216, respectively. As of December 31, 2014, we expected 60% achievement of the predefined revenue, revenue growth and ROIC targets associated with the awards of PUs made in 2014.
A summary of PU activity for the year ended December 31, 2014 is as follows:
		Original		PU Adjustment(1)	Total	Weighted-
		PU Awards			PU Awards	Average
						Grant-Date
						Fair Value

						30.80
	-1		Represents an increase or decrease in the number of original PUs awarded based on either (a) the final performance criteria achievement at the end of the defined performance period of such PUs or (b) a change in estimated awards based on the forecasted performance against the predefined targets.
Employee Stock Purchase Plan
We offer an ESPP in which participation is available to substantially all United States and Canadian employees who meet certain service eligibility requirements. The ESPP provides a way for our eligible employees to become stockholders on favorable terms. The ESPP provides for the purchase of our common stock by eligible employees through successive offering periods. We have historically had two six-month offering periods per year, the first of which generally runs from June 1 through November 30 and the second of which generally runs from December 1 through May 31. During each offering period, participating employees accumulate after-tax payroll contributions, up to a maximum of 15% of their compensation, to pay the purchase price at the end of the offering. Participating employees may withdraw from an offering before the purchase date and obtain a refund of the amounts withheld as payroll deductions. At the end of the offering period, outstanding options under the ESPP are exercised, and each employee’s accumulated contributions are used to purchase our common stock. The price for shares purchased under the ESPP is 95% of the fair market price at the end of the offering period, without a look-back feature. As a result, we do not recognize compensation expense for the ESPP shares purchased. For the years ended December 31, 2012, 2013 and 2014, there were 151,285 shares, 144,432 shares and 115,046 shares, respectively, purchased under the ESPP. As of December 31, 2014, we have 960,638 shares available under the ESPP.
As of December 31, 2014, unrecognized compensation cost related to the unvested portion of our Employee Stock-Based Awards was $35,467 and is expected to be recognized over a weighted-average period of 1.9 years.
We generally issue shares of our common stock for the exercises of stock options, restricted stock, RSUs, PUs and shares of our common stock under our ESPP from unissued reserved shares.
Income Taxes
	o.Income Taxes
	Accounting for income taxes requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the tax and financial reporting bases of assets and liabilities and for loss and credit carryforwards. Valuation allowances are provided when recovery of deferred tax assets does not meet the more likely than not standard as defined in GAAP. We have elected to recognize interest and penalties associated with uncertain tax positions as a component of the provision (benefit) for income taxes in the accompanying Consolidated Statements of Operations.
Income (Loss) Per Share-Basic and Diluted
	p.Income (Loss) Per Share—Basic and Diluted
	Basic income (loss) per common share is calculated by dividing income (loss) by the weighted average number of common shares outstanding. The calculation of diluted income (loss) per share is consistent with that of basic income (loss) per share but gives effect to all potential common shares (that is, securities such as options, warrants or convertible securities) that were outstanding during the period, unless the effect is antidilutive.
	The following table presents the calculation of basic and diluted income (loss) per share:
			Year Ended December 31,

Allowance for Doubtful Accounts and Credit Memo Reserves
	q.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.
	Rollforward of allowance for doubtful accounts and credit memo reserves is as follows:

		-1		Money market funds and time deposits (including certain trading securities) are measured based on quoted prices for similar assets and/or subsequent transactions.
		-2		Securities are measured at fair value using quoted market prices.
		-3		Our derivative assets and liabilities primarily relate to short- term (six months or less) foreign currency contracts that we have entered into to hedge certain of our intercompany exposures, as more fully disclosed at Note 3. We calculate the fair value of such forward contracts by adjusting the spot rate utilized at the balance sheet date for translation purposes by an estimate of the forward points observed in active markets.

		-1		The capital stock or other equity interests of most of our United States subsidiaries, and up to 66% of the capital stock or other equity interests of our first-tier foreign subsidiaries, are pledged to secure these debt instruments, together with all intercompany obligations (including promissory notes) of subsidiaries owed to us or to one of our United States subsidiary guarantors. In addition, Iron Mountain Canada Operations ULC (“Canada Company”) has pledged 66% of the capital stock of its subsidiaries, and all intercompany obligations (including promissory notes) owed to or held by it, to secure the Canadian dollar subfacility under the Revolving Credit Facility (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, 2013 and 2014, 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, 2013 and 2014, 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 substantially all of its direct and indirect 100% owned United States subsidiaries (the “Guarantors”). These guarantees are joint and several obligations of the Guarantors. Canada Company, Iron Mountain Europe PLC (“IME”) and the remainder of our subsidiaries do not guarantee the Parent Notes.
		-4		Canada Company is the direct obligor on the CAD Notes, which are fully and unconditionally guaranteed, on a senior basis, by IMI and the Guarantors. These guarantees are joint and several obligations of IMI and the Guarantors. See Note 5 to Notes to Consolidated Financial Statements.
		-5		IME is the direct obligor on the GBP Notes, which are fully and unconditionally guaranteed, on a senior basis, by IMI and the Guarantors. These guarantees are joint and several obligations of IMI and the Guarantors. See Note 5 to Notes to Consolidated Financial Statements.
		-6		Includes (a) real estate mortgages of $3,704 and $5,107 as of December 31, 2013 and 2014, respectively, which bear interest at approximately 4.5% and are payable in various installments through 2021, (b) capital lease obligations of $255,124 and $241,866 as of December 31, 2013 and 2014, respectively, which bear a weighted average interest rate of 5.8% at both December 31, 2013 and 2014, and (c) other various notes and other obligations, which were assumed by us as a result of certain acquisitions, of $39,619 and $73,729 as of December 31, 2013 and 2014, respectively, and bear a weighted average interest rate of 14.3% and 11.5% as of December 31, 2013 and 2014, respectively. We believe the fair value (Level 3 of fair value hierarchy described at Note 2.s.) of this debt approximates its carrying value.

		-1		The change in net income (loss) attributable to Iron Mountain Incorporated in the fourth quarter of 2013 compared to the third quarter of 2013 is primarily attributable to a benefit for income taxes recorded in the fourth quarter of 2013 compared to a provision recorded in the third quarter of 2013 for a net benefit of approximately $50,200, as well as a decrease in other expenses, net of approximately $34,700 primarily as a result of debt extinguishment charges recorded in the third quarter of 2013 of approximately $43,600 that did not repeat in the fourth quarter of 2013, offset by an increase in foreign exchange transaction losses of approximately $11,000. Offsetting these benefits was a decrease in operating income of approximately $42,900. The decrease in operating income is primarily attributable to: (1) $18,700 of restructuring costs associated with our organizational realignment, (2) $11,200 of facilities costs primarily associated with facility consolidation, (3) $8,100 of other cost increases, including costs associated with recent acquisitions and executing our strategy, (4) $3,600 of increased depreciation and amortization, primarily related to business acquisitions, (5) $3,000 in sales, marketing and account management costs within our North American Records and Information Management Business and North American Data Management Business segments (primarily associated with sales commissions), (6) $2,200 of increased bad debt expense and (7) $2,000 of charitable contributions, partially offset by a $7,100 decrease in REIT Costs (defined at Note 9) incurred in the fourth quarter compared to the third quarter of 2013.
		-2		The change in net income (loss) attributable to Iron Mountain Incorporated in the fourth quarter of 2014 compared to the third quarter of 2014 is primarily attributable to a decrease in the provision for income taxes recorded in the fourth quarter of 2014 compared to the third quarter of 2014 of approximately $54,000. The decrease in the income tax provision was offset by a decrease in operating income of approximately $13,600, a debt extinguishment charge recorded in the fourth quarter of 2014 of approximately $16,500 and an increase in interest expense of $9,800. The decrease in operating income is attributable to a $8,300 increase in selling, general and administrative expenses, primarily due to higher professional fees and charitable contributions, as well as a $4,700 decrease in revenue, primarily due to unfavorable changes in foreign exchange rates, in the fourth quarter compared to the third quarter.
