	(1) General
	The interim consolidated financial statements are presented herein and, in the opinion of management, reflect all adjustments of a normal recurring nature necessary for a fair presentation. Interim results are not necessarily indicative of results for a full year. Iron Mountain Incorporated and its subsidiaries ("IMI", "we" or "us") store records, primarily paper documents and data backup media, and provide information management services in various locations throughout North America, Europe, Latin America and Asia Pacific. We have a diversified customer base consisting of commercial, legal, banking, health care, accounting, insurance, entertainment and government organizations.
	The unaudited consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in the annual financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") have been omitted pursuant to those rules and regulations, but we believe that the disclosures included herein are adequate to make the information presented not misleading. The Consolidated Financial Statements and Notes thereto, which are included herein, should be read in conjunction with the Consolidated Financial Statements and Notes thereto for the year ended December 31, 2012 included in our Annual Report on Form 10-K filed on March 1, 2013.
	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 10 for a further discussion of these events.

Summary of Significant Accounting Policies	'
	(2) Summary of Significant Accounting Policies
	a.
	Principles of Consolidation
	The accompanying financial statements reflect our financial position, results of operations, comprehensive income (loss), equity and cash flows on a consolidated basis. All intercompany account balances have been eliminated.
	b.
	Cash, Cash Equivalents and Restricted Cash
	Cash and cash equivalents include cash on hand and cash invested in 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 $33,612 and $33,613 as of December 31, 2012 and September 30, 2013, respectively, and is included in current assets on our Consolidated Balance Sheets. Restricted cash consists primarily of U.S. Treasuries.
	c.
	Foreign Currency
	Local currencies are the functional currencies for our operations outside the U.S., with the exception of certain foreign holding companies and our financing center in Switzerland, whose functional currency is the U.S. 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 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 facilities 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 gain or loss on foreign currency transactions amounted to a net gain of $1,131 and a net loss of $8,055 for the three and nine months ended September 30, 2012, respectively. The total gain or loss on foreign currency transactions amounted to a net loss of $2,612 and $22,543 for the three and nine months ended September 30, 2013, respectively.

	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 assess whether a change in the life over which our intangible assets are amortized is necessary or more frequently if events or circumstances warrant.
	We have selected October 1 as our annual goodwill impairment review date. We performed our most recent annual goodwill impairment review as of October 1, 2012 and noted no impairment of goodwill at such date. As of December 31, 2012 and September 30, 2013, no factors were identified that would alter our October 1, 2012 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, 2012 were as follows: (1) North America; (2) United Kingdom, Ireland, Norway, Belgium, France, Germany, Luxembourg, Netherlands and Spain ("Western Europe"); (3) the remaining countries in Europe, excluding Russia and Ukraine, in which we operate ("Emerging Markets"); (4) Latin America; (5) Australia, China, Hong Kong and Singapore ("Asia Pacific"); and (6) India, Russia and Ukraine ("Emerging Market Joint Ventures"). As of December 31, 2012, the carrying value of goodwill, net amounted to $1,762,307, $365,303, $87,492, $56,893 and $62,764 for North America, Western Europe, Emerging Markets, Latin America and Asia Pacific, respectively. Our Emerging Market Joint Ventures reporting unit had no goodwill as of December 31, 2012 and September 30, 2013. Based on our goodwill impairment assessment, all of our reporting units with goodwill had estimated fair values as of October 1, 2012 that exceeded their carrying values by greater than 30%. As of September 30, 2013, the carrying value of goodwill, net amounted to $1,764,736, $368,240, $87,322, $99,457 and $56,326 for North America, Western Europe, Emerging Markets, Latin America and Asia Pacific, respectively.
	Reporting unit valuations have been calculated using an income approach based on the present value of future cash flows of each reporting unit or a combined approach based on the present value of future cash flows and market and transaction 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 nine months ended September 30, 2013 are as follows:
		North			International			Total
		American			Business			Consolidated
		Business
	Gross Balance as of December 31, 2012	$	2,023,971		$	631,528		$	2,655,499

	Total fair value and other adjustments primarily include $(143) in net adjustments to property, plant and equipment, net, customer relationships and deferred income taxes made within one year from the date of the acquisition, as well as $74 of cash received related to acquisitions made in previous years.
	The components of our amortizable intangible assets as of September 30, 2013 are as follows:
		Gross Carrying			Accumulated			Net Carrying
		Amount			Amortization			Amount
	Customer Relationships and Acquisition Costs	$	749,818		$	(261,510	)	$	488,308

	Included in Other Assets, net in the accompanying Consolidated Balance Sheets.
	Amortization expense associated with amortizable intangible assets (including deferred financing costs) was $12,128 and $31,335 for the three and nine months ended September 30, 2012, respectively. Amortization expense associated with amortizable intangible assets (including deferred financing costs) was $10,404 and $33,393 for the three and nine months ended September 30, 2013, respectively.

	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, performance units and shares of stock issued under the 2003 employee stock purchase plan (together, "Employee Stock-Based Awards").
	Stock-based compensation expense for Employee Stock-Based Awards included in the accompanying Consolidated Statements of Operations for the three and nine months ended September 30, 2012 was $4,682 ($3,836 after tax or $0.02 per basic and diluted share) and $20,799 ($15,744 after tax or $0.09 per basic and diluted share), respectively. Stock-based compensation expense for Employee Stock-Based Awards for the three and nine months ended September 30, 2013 was $9,423 ($6,590 after tax or $0.03 per basic and diluted share) and $23,016 ($17,576 after tax or $0.09 per basic and diluted share), respectively.
	Stock-based compensation expense for Employee Stock-Based Awards included in the accompanying Consolidated Statements of Operations related to continuing operations is as follows:
		Three Months						Nine Months Ended
		Ended						September 30,
		September 30,
		2012			2013			2012			2013
	Cost of sales (excluding depreciation and amortization)	$	329		$	115		$	846		$	257
	Selling, general and administrative expenses		4,353			9,308			19,953			22,759
	Total stock-based compensation	$	4,682		$	9,423		$	20,799		$	23,016
	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 $309 and $2,499 for the nine months ended September 30, 2012 and 2013, respectively, from the benefits of tax deductions in excess of 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 were granted with exercise prices equal to 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 September 30, 2013, ten-year vesting options represented 10.4% of total outstanding options. Beginning in 2011, 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 September 30, 2013, three-year vesting options represented 20.3% 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.
	The weighted average fair value of options granted for the nine months ended September 30, 2012 and 2013 was $7.00 and $7.69 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 respective period:
	Nine Months Ended
	September 30,
Weighted Average Assumptions	2012			2013
Expected volatility		33.8	%		33.8	%
Risk-free interest rate		1.24	%		1.13	%
Expected dividend yield		3	%		3	%
Expected life		6.3 years			6.3 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 U.S. 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 our employees.
A summary of option activity for the nine months ended September 30, 2013 is as follows:
	Options			Weighted			Weighted			Aggregate
				Average			Average			Intrinsic
				Exercise			Remaining			Value
				Price			Contractual

Restricted Stock and Restricted Stock Units
Under our various stock option plans, we may also issue grants of restricted stock or restricted stock units ("RSUs"). Our restricted stock and RSUs generally have a three- to five-year vesting period from the date of grant. As a result of an amendment to our RSUs approved by our Compensation Committee of our board of directors in October 2012, all RSUs now 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 $8 and $42 of cash dividends on RSUs for the three and nine months ended September 30, 2012, respectively. We accrued approximately $378 and $1,476 of cash dividends on RSUs for the three and nine months ended September 30, 2013, respectively. There were no cash dividends paid on RSUs for the three and nine months ended September 30, 2012, respectively. We paid approximately $121 and $674 of cash dividends on RSUs for the three and nine months ended September 30, 2013, 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 nine months ended September 30, 2013 is as follows:
	Restricted			Weighted-
	Stock and RSUs			Average
				Grant-Date
				Fair Value
Non-vested at December 31, 2012		1,303,664		$	29.89
Granted		638,469			35.35
Vested		(474,586	)		29.97
Forfeited		(54,458	)		29.95
Non-vested at September 30, 2013		1,413,089		$	32.33
The total fair value of restricted stock vested during each of the three months ended September 30, 2012 and 2013 was $0. The total fair value of restricted stock vested during each of the nine months ended September 30, 2012 and 2013 was $1. The total fair value of RSUs vested during the nine months ended September 30, 2012 was $5,962. The total fair value of RSUs vested during the three and nine months ended September 30, 2013 was $2,145 and $14,221, respectively.
Performance Units
Under our various equity compensation plans, we may also make awards of performance units ("PUs"). For the majority of PUs, the number of PUs earned is determined based on our performance against predefined calendar year targets of revenue growth and return on invested capital ("ROIC"). The number of PUs earned may range from 0% to 150% of the initial award. The number of PUs earned is determined based on the Company's actual performance as compared to the targets at the end of the one-year performance period. Certain PUs granted in 2013 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. 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 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. As a result of an amendment to our PUs approved by our Compensation Committee of our board of directors in October 2012, outstanding PUs now 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 $146 and $535 of cash dividends on PUs for the three and nine months ended September 30, 2013, respectively.
During the nine months ended September 30, 2013, we issued 198,869 PUs. For PUs that are earned based on our performance against revenue growth and ROIC targets during the one-year performance period, we forecast the likelihood of achieving the predefined annual 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 one-year performance period) or the actual PUs earned (at the one-year anniversary date) over the vesting period for each of the awards. For the 2013 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 nine months ended September 30, 2012 was $3,505. The total fair value of earned PUs that vested during the nine months ended September 30, 2013 was $996. There were no cash dividends paid on PUs for both the three and nine months ended September 30, 2012 and 2013. As of September 30, 2013, we expected 87.0% achievement of the predefined revenue and ROIC targets associated with the awards of PUs made in 2013.
A summary of PU activity for the nine months ended September 30, 2013 is as follows:
	Original			PU Adjustment(1)			Total			Weighted-
	PU Awards						PU Awards			Average

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 employee stock purchase plan (the "ESPP") in which participation is available to substantially all U.S. 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 cost for the ESPP shares purchased. For the nine months ended September 30, 2012 and 2013, there were 88,672 shares and 74,732 shares, respectively, purchased under the ESPP. The number of shares available for purchase under the ESPP at September 30, 2013 was 204,494. We anticipate that the ESPP will be replaced subsequent to the expiration of our June 1 offering on November 29, 2013, by the Iron Mountain Incorporated 2013 Employee Stock Purchase Plan, which was approved by our stockholders at the 2013 Annual Meeting of Stockholders held on June 6, 2013. We anticipate that beginning November 29, 2013, we will have 1,000,000 shares available under the ESPP.
As of September 30, 2013, unrecognized compensation cost related to the unvested portion of our Employee Stock-Based Awards was $50,735 and is expected to be recognized over a weighted-average period of 2.1 years.
We generally issue shares of our common stock for the exercises of stock options, restricted stock, RSUs, PUs and shares of our common stock under our ESPP from unissued reserved shares.

Income (Loss) Per Share—Basic and Diluted
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:

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 core service activities and a wide array of complementary products and services. Included in core service revenues are: (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 (4) other recurring services, including Document Management Solutions, which relate to physical and digital records, and recurring project revenues. Our complementary services revenues include special project work, customer termination and permanent withdrawal fees, data restoration projects, fulfillment services, consulting services, technology services and product sales (including specially designed storage containers and related supplies). Our secure shredding revenues include the sale of recycled paper (included in complementary services revenues), the price of which can fluctuate from period to period, adding to the volatility and reducing the predictability of that revenue stream.
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 is included as a component of service revenues, is recognized when products are shipped and title has passed to the customer. Revenues from the sales of products have historically not been significant.
h.
Allowance for Doubtful Accounts and Credit Memo Reserves
We maintain an allowance for doubtful accounts and credit memos for estimated losses resulting from the potential inability of our customers to make required payments and potential disputes regarding billing and service issues. When calculating the allowance, we consider our past loss experience, current and prior trends in our aged receivables and credit memo activity, current economic conditions and specific circumstances of individual receivable balances. If the financial condition of our customers were to significantly change, resulting in a significant improvement or impairment of their ability to make payments, an adjustment of the allowance may be required. We consider accounts receivable to be delinquent after such time as reasonable means of collection have been exhausted. We charge-off uncollectible balances as circumstances warrant, generally, no later than one year past due.
i.
Income Taxes
Our effective tax rates for the three and nine months ended September 30, 2012 were 36.7% and 40.3%, respectively. Our effective tax rates for the three and nine months ended September 30, 2013 were 81.5% and 63.4%, respectively. The primary reconciling items between the federal statutory rate of 35% and our overall effective tax rate 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), and the planned repatriation discussed below. During the three and nine months ended September 30, 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 5.6% and 1.2%, respectively. During the three months ended September 30, 2013, foreign currency gains were recorded in lower tax jurisdictions associated with our marking-to-market of intercompany loans while foreign currency losses were recorded in higher tax jurisdictions associated with our marking-to-market of debt and derivative instruments, which decreased our 2013 effective tax rate by 47.0%. During the three and nine months ended September 30, 2013, the planned repatriation discussed below increased our 2013 effective tax rate by 87.1% and 18.5%, respectively. Also, during the three and nine months ended September 30, 2013, we incurred non-deductible transaction costs related to our potential conversion to a REIT, which increased our 2013 effective tax rate by 10.1% and 4.7%, respectively.
On January 2, 2013, the American Taxpayer Relief Act of 2012 (the "ATRA") was signed into law. In part, the ATRA retroactively reinstated and extended the controlled foreign corporation look-through rule, which provides for the exception from January 1, 2012 to December 31, 2013 of certain foreign earnings from U.S. federal taxation as Subpart F income. As a result, our income tax provision for the first quarter of 2013 included a discrete tax benefit of $4,025 relating to the previously expired period from January 1, 2012 to December 31, 2012.
On September 13, 2013, the Internal Revenue Service released final tangible property regulations under Sections 162(a) and 263(a) of the Internal Revenue Code of 1986 (the "Code"), regarding the deduction and capitalization of expenditures related to tangible property. The final regulations replace temporary regulations that were issued in December 2011. Also released were proposed regulations under Section 168 of the Code regarding dispositions of tangible property. These final and proposed regulations will be effective for our tax year beginning on January 1, 2014. Early adoption is available, and as such, we intend to elect early adoption of the regulations. Changes for tax treatment elected by us or required by the regulations will generally be effective prospectively; however, implementation of many of the regulations' provisions will require a calculation of the cumulative effect of the changes on prior years, and it is expected that such amount will have to be included in the determination of our taxable income over a four-year period beginning in 2013. Transition guidance providing the procedural rules to comply with such regulations is expected to be released in the near term. We do not believe these regulations will have a material impact on our consolidated results of operations, cash flows and financial position.
We provide for income taxes during interim periods based on our estimate of the effective tax rate for the year. Discrete items and changes in our estimate of the annual effective tax rate are recorded in the period they occur. Our effective tax rate is subject to variability in the future due to, among other items: (1) changes in the mix of income from foreign jurisdictions; (2) tax law changes; (3) volatility in foreign exchange gains (losses); (4) the timing of the establishment and reversal of tax reserves; (5) our ability to utilize foreign tax credits and net operating losses that we generate; and (6) our proposed conversion to a real estate investment trust ("REIT"). We are subject to income taxes in the U.S. and numerous foreign jurisdictions. We are subject to examination by various tax authorities in jurisdictions in which we have business operations or a taxable presence. We regularly assess the likelihood of additional assessments by tax authorities and provide for these matters as appropriate. Although we believe our tax estimates are appropriate, the final determination of tax audits and any related litigation could result in changes in our estimates.
Accounting for income taxes requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the tax and financial reporting basis of assets and liabilities and for loss and credit carryforwards. Valuation allowances are provided when recovery of deferred tax assets does not meet the more likely than not standard as defined in GAAP.
We have elected to recognize interest and penalties associated with uncertain tax positions as a component of the provision (benefit) for income taxes in the accompanying Consolidated Statements of Operations. We recorded an increase of $922 and $920 for gross interest and penalties for the three and nine months ended September 30, 2012, respectively. We recorded an increase of $1,014 and $1,735 for gross interest and penalties for the three and nine months ended September 30, 2013, respectively. We had $3,554 and $5,225 accrued for the payment of interest and penalties as of December 31, 2012 and September 30, 2013, respectively.
During the three months ended September 30, 2013, we developed a plan to utilize both current and carryforward foreign tax credits by repatriating approximately $253,000 (approximately $53,000 of which we had previously paid U.S. 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. We anticipate completing this plan in the fourth quarter of 2013. As a result, we recorded an increase in our tax provision from continuing operations in the amount of approximately $71,400 in the three months ended September 30, 2013. This increase was offset by decreases of approximately $23,500 from current year foreign tax credits and approximately $21,900 reversal of valuation allowances related to foreign tax credit carryforwards, resulting in a net increase of approximately $26,000 in our tax provision from continuing operations.
After the planned repatriation, we will have a net tax over book outside basis difference related to our foreign subsidiaries. We do not expect this net basis difference to reverse in the foreseeable future and we intend to reinvest any future undistributed earnings of certain foreign subsidiaries indefinitely outside the U.S. We have instances where we have book over tax outside basis differences for certain foreign subsidiaries. These basis differences arose primarily through the undistributed book earnings of such foreign subsidiaries. These basis differences could be reversed through a sale of such foreign subsidiaries, the receipt of dividends from such subsidiaries or certain other events or actions on our part, each of which would result in an increase in our provision for income taxes. It is not practicable to calculate the amount of unrecognized deferred tax liability on these book over tax outside basis difference because of the complexities of the hypothetical calculation. We may record additional deferred taxes on book over tax outside basis differences related to certain foreign subsidiaries in the future depending upon a number of factors, decisions and events in connection with our potential conversion to a REIT, including favorable indications from the U.S. Internal Revenue Service with regard to our private letter ruling requests, finalization of countries to be included in our plan to convert to a REIT, shareholder approval of certain modifications to our corporate charter and final board of director approval of our conversion to a REIT.
As of September 30, 2013, we have reclassified approximately $27,500 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 recharacterization of certain racking structures as real estate rather than personal property and amortization associated with other intangible assets in conjunction with our potential conversion to a REIT.
j.
Concentrations of Credit Risk
Financial instruments that potentially subject us to market risk consist principally of cash and cash equivalents (including money market funds and time deposits), restricted cash (primarily U.S. Treasuries) and accounts receivable. The only significant concentrations of liquid investments as of both December 31, 2012 and September 30, 2013 relate to cash and cash equivalents and restricted cash held on deposit with five global banks and two "Triple A" rated money market funds, and two global banks and four "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, 2012 and September 30, 2013, our cash and cash equivalents and restricted cash balance was $277,027 and $205,644, respectively, including money market funds and time deposits amounting to $218,629 and $79,360, respectively. A substantial portion of the money market funds is invested in U.S. Treasuries.
k.
Fair Value Measurements
Entities are permitted under GAAP to elect to measure many financial instruments and certain other items at either fair value or cost. We did not elect the fair value measurement option for any of our financial assets or liabilities.
Our financial assets or liabilities are 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, 2012 and September 30, 2013, 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 our intercompany exposures denominated in British pounds sterling and Australian dollars. 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 three and nine months ended September 30, 2013.
l.
Use of Estimates
The preparation of financial statements in conformity with GAAP requires us to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities at the date of the financial statements and for the period then ended. On an ongoing basis, we evaluate the estimates used. We base our estimates on historical experience, actuarial estimates, current conditions and various other assumptions that we believe to be reasonable under the circumstances. These estimates form the basis for making judgments about the carrying values of assets and liabilities and are not readily apparent from other sources. Actual results may differ from these estimates.

Property, Plant and Equipment and Long-Lived Assets
We develop various software applications for internal use. Computer software costs associated with internal use software are expensed as incurred until certain capitalization criteria are met. Payroll and related costs for employees directly associated with, and devoting time to, the development of internal use computer software projects (to the extent time is spent directly on the project) are capitalized. 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. Depreciation begins when the software is placed in service. Computer software costs that are capitalized are periodically evaluated for impairment.
We review long-lived assets and all amortizable intangible assets for impairment whenever events or changes in circumstances indicate the carrying amount of such assets may not be recoverable. Recoverability of these assets is determined by comparing the forecasted undiscounted net cash flows of the operation to which the assets relate to their carrying amount. The operations are generally distinguished by the business segment and geographic region in which they operate. If the operation is determined to be unable to recover the carrying amount of its assets, then intangible assets are written down first, followed by the other long-lived assets of the operation, to fair value. Fair value is determined based on discounted cash flows or appraised values, depending upon the nature of the assets.
Consolidated gain on disposal/write-down of property, plant and equipment, net was $173 and $2,375 for the three and nine months ended September 30, 2013, respectively, and consisted primarily of gains on the retirement of leased vehicles accounted for as capital lease assets associated with our North American Business segment and the sale of a building in the United Kingdom. Consolidated gain on disposal/write-down of property, plant and equipment, net was $1,515 for the nine months ended September 30, 2012 and consisted primarily of approximately $2,700 of gains associated with the sale of leased vehicles in North America, partially offset by approximately $700 of asset write-offs in North America and approximately $500 of asset write-offs associated with our Latin America operations.

(3) Derivative Instruments and Hedging Activities

Every derivative instrument is required to be recorded in the balance sheet as either an asset or a liability measured at its fair value. Periodically, we acquire derivative instruments that are intended to hedge either cash flows or values that are subject to foreign exchange or other market price risk and not for trading purposes. We have formally documented our hedging relationships, including identification of the hedging instruments and the hedged items, as well as our risk management objectives and strategies for undertaking each hedge transaction. Given the recurring nature of our revenues and the long-term nature of our asset base, we have the ability and the preference to use long-term, fixed interest rate debt to finance our business, thereby preserving our long-term returns on invested capital. We target approximately 75% of our debt portfolio to be fixed with respect to interest rates. Occasionally, we may use interest rate swaps as a tool to maintain our targeted level of fixed rate debt. In addition, we may use borrowings in foreign currencies, either obtained in the U.S. 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, 2012 and September 30, 2013, none of our derivative instruments contained credit-risk related contingent features.

We have entered into a number of separate forward contracts to hedge our exposures in British pounds sterling and Australian dollars. As of September 30, 2013, we had (1) outstanding forward contracts to purchase $194,858 U.S. dollars and sell 125,000 British pounds sterling to hedge our intercompany exposures with our European operations and (2) an outstanding forward contract to purchase $71,610 U.S. dollars and sell 77,000 Australian dollars to hedge our intercompany exposures with our Australian subsidiary. 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 (income) expense, net in the accompanying 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 these forward contracts as hedges. During the three and nine months ended September 30, 2012, there were $4 in net cash receipts and $3,783 in net cash disbursements, respectively, included in cash from operating activities from continuing operations related to settlements associated with these foreign currency forward contracts. During the three and nine months ended September 30, 2013, there were $4,764 in net cash disbursements and $11,511 in net cash receipts, respectively, included in cash from operating activities from continuing operations related to settlements associated with these foreign currency forward contracts.

The following table provides the fair value of our derivative instruments as of December 31, 2012 and September 30, 2013 and their gains and losses for the three and nine months ended September 30, 2012 and 2013:

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 nine months ended September 30, 2012 and 2013, we designated on average 101,556 and 107,667 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 foreign exchange losses of $2,303 ($1,401, net of tax) and $938 ($535, net of tax) for the three and nine months ended September 30, 2012, respectively, related to the change in fair value of such debt due to currency translation adjustments, which is a component of accumulated other comprehensive items, net included in Iron Mountain Incorporated Stockholders' Equity in the accompanying Consolidated Balance Sheets. We recorded foreign exchange losses of $5,467 ($3,333, net of tax) and foreign exchange losses of $3,374 ($2,057, net of tax) for the three and nine months ended September 30, 2013, respectively, related to the change in fair value of such debt due to currency translation adjustments, which is a component of accumulated other comprehensive items, net included in Iron Mountain Incorporated Stockholders' Equity in the accompanying Consolidated Balance Sheets. As of September 30, 2013, cumulative net gains of $8,665, net of tax are recorded in accumulated other comprehensive items, net associated with this net investment hedge.

	(4) Acquisitions
	We account for acquisitions using the acquisition method of accounting, and, accordingly, 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 for the three and nine months ended September 30, 2013 are not presented due to the insignificant impact of the 2012 and 2013 acquisitions on our consolidated results of operations. Noteworthy 2013 acquisitions are as follows:
	In May 2013, in order to further enhance our existing operations in the U.S., 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. Included in the purchase price is approximately $1,600 held in escrow to secure a post-closing working capital adjustment. The amounts held in escrow for purposes of the post-closing working capital adjustment will be distributed either to us or the former owners based on the final agreed upon post-closing working capital amount.
	In June 2013, in order to further 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.
	In September 2013, in order to further 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, subject to post-closing working capital and net debt adjustments. 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, subject to post-closing working capital and net debt adjustments.
	A summary of the cumulative consideration paid and the preliminary allocation of the purchase price paid for acquisitions in 2013 through September 30, 2013 is as follows:
	Cash Paid (gross of cash acquired)	$	125,487	-1
	Total Consideration		125,487

	Total Fair Value of Identifiable Net Assets Acquired		66,403
	Goodwill Initially Recorded	$	59,084
	-1
	Included in cash paid for acquisitions in the accompanying Consolidated Statements of Cash Flows for the nine months ended September 30, 2013 is cash received of $2,806 related to acquisitions made in the current and previous years.
	-2
	Consists primarily of racking structures, leasehold improvements and computer hardware and software.
	-3
	The weighted average lives of customer relationship assets associated with acquisitions to date in 2013 was 18 years.
	-4
	Consists primarily of accounts payable, accrued expenses, notes payable, deferred revenue and deferred income taxes.
	Allocations of the purchase price for acquisitions completed in 2013 were based on estimates of the fair value of net assets acquired and are subject to adjustment. We are not aware of any information that would indicate that the final purchase price allocations will differ meaningfully from preliminary estimates. The purchase price allocations of the 2013 acquisitions are subject to finalization of the assessment of the fair value of intangible assets (primarily customer relationship assets), property, plant and equipment (primarily racking structures), leases, contingencies and income taxes (primarily deferred income taxes).

	The capital stock or other equity interests of most of our U.S. 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 U.S. subsidiary guarantors. In addition, Iron Mountain Canada Operations ULC (f/k/a Iron Mountain Canada Corporation) ("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 these debt instruments. The fair value (Level 3 of fair value hierarchy described at Note 2.k.) of this long-term debt 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, 2012 and September 30, 2013, respectively.

These guarantees are joint and several obligations of the Guarantors. Canada Company and the remainder of our subsidiaries do not guarantee the Parent Notes.

	Canada Company is the direct obligor on the Senior Subordinated Subsidiary Notes and Senior Subsidiary Notes, which are fully and unconditionally guaranteed, on a senior or senior subordinated basis, by IMI and the Guarantors. These guarantees are joint and several obligations of IMI and the Guarantors. See Note 6 to Notes to Consolidated Financial Statements.

	The fair value (Level 3 of fair value hierarchy described at Note 2.k.) of this debt approximates its carrying value.
	On August 7, 2013, we amended our existing credit agreement. The revolving credit facilities (the "Revolving Credit Facility") under our credit agreement, as so amended (the "Credit Agreement") allow IMI and certain of its U.S. and foreign subsidiaries to borrow in U.S. 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. We have the right to request an increase in the aggregate amount available to be borrowed under the Credit Agreement up to a maximum of $2,000,000. At the time of the amendment, we repaid all term loans outstanding under our initial principal amount of $500,000 term loan facility under the original credit agreement. The Revolving Credit Facility terminates on June 27, 2016, at which point all obligations under the Credit Agreement become due. IMI and most of its U.S. subsidiaries guarantee all obligations under the Credit Agreement, and have pledged the capital stock or other equity interests of most of their U.S. 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 Credit Agreement. The interest rate on borrowings under the Credit Agreement varies depending on our choice of interest rate and currency options, plus an applicable margin, which varies based on our consolidated leverage ratio. Additionally, the Credit Agreement requires the payment of a commitment fee on the unused portion of the Revolving Credit Facility, which fee ranges from between 0.3% to 0.5% based on certain financial ratios. There are also fees associated with any outstanding letters of credit. As of September 30, 2013, we had $523,968 of outstanding borrowings under the Revolving Credit Facility, $380,650 was denominated in U.S. dollars, 91,000 in Canadian dollars and 40,715 in Euros; we also had various outstanding letters of credit totaling $2,316. The remaining availability under the Revolving Credit Facility on September 30, 2013, based on IMI's leverage ratio, which is calculated based on the last 12 months' earnings before interest, taxes, depreciation and amortization ("EBITDA"), and other adjustments as defined in the Credit Agreement and current external debt, was $973,716. The average interest rate in effect under the Revolving Credit Facility was 2.7% and ranged from 2.4% to 4.5% as of September 30, 2013. For the three and nine months ended September 30, 2012, we recorded commitment fees and letters of credit fees of $562 and $1,611, respectively, based on the unused balances under our revolving credit facilities and outstanding letters of credit. For the three and nine months ended September 30, 2013, we recorded commitment fees and letters of credit fees of $977 and $2,133, 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 the amendment of our revolving credit and term loan facilities, representing a write-off of deferred financing costs.
	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 Senior Subsidiary 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 all of the outstanding Senior Subordinated Subsidiary Notes, 8% Notes and 8% Notes due 2020, and to fund the purchase of $137,500 in principal amount of the 83/8% Notes pursuant to a tender offer. The remaining net proceeds were used to repay existing indebtedness under our Revolving Credit Facility.
	In August 2013, we redeemed (1) the 175,000 CAD aggregate principal amount outstanding of our Senior Subordinated Subsidiary Notes at 102.5% of par, plus accrued and unpaid interest, (2) the $50,000 aggregate principal amount outstanding of our 8% Notes at 102.7% of par, plus accrued and unpaid interest, (3) the $300,000 aggregate principal amount outstanding of our 8% Notes due 2020 at 104.0% of par, plus accrued and unpaid interest, and (4) $137,500 aggregate principal amount outstanding of our 83/8% Notes at 109.8% of par, plus accrued and unpaid interest. 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.
	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, as amended on August 7, 2013, uses EBITDA plus rent expense ("EBITDAR"), or 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 4.9 as of September 30, 2013 (compared to a maximum allowable ratio of 6.5), and its net secured debt lease adjusted leverage ratio was 2.0 as of September 30, 2013 (compared to a maximum allowable ratio of 4.0). IMI's bond leverage ratio (which is not lease adjusted), per the indentures, was 5.3 and 4.9 as of December 31, 2012 and September 30, 2013, respectively, compared to a maximum allowable ratio of 6.5. IMI's Credit Agreement, as amended on August 7, 2013, fixed charge coverage ratio was 2.4 as of September 30, 2013, 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.

Selected Consolidated Financial Statements of Parent, Guarantors, Canada Company and Non-Guarantors	'
	(6) Selected Consolidated Financial Statements of Parent, Guarantors, Canada Company and Non-Guarantors
	The following data summarizes the consolidating results of IMI on the equity method of accounting as of December 31, 2012 and September 30, 2013 and for the three and nine months ended September 30, 2012 and 2013 and are prepared on the same basis as the consolidated financial statements.
	The Parent Notes and the Senior Subsidiary 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 Senior Subsidiary Notes which were issued by Canada Company. Canada Company does not guarantee the Parent Notes. The other subsidiaries that do not guarantee the Parent Notes or the Senior Subsidiary Notes 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.
	In July 2013, certain of Canada Company's operating subsidiaries (the "Amalgamated Entities") were amalgamated into Canada Company and, as part of our proposed conversion to a REIT, Canada Company contributed certain assets and liabilities into two newly-formed wholly owned entities (the "Canadian Subsidiaries"). The assets, liabilities, equity, results of operations and cash flows of the Amalgamated Entities, previously presented within the Non-Guarantors column, are now presented within the Canada Company column. The assets, liabilities, equity, results of operations and cash flows of the Canadian Subsidiaries, previously presented within the Canada Company column, are now presented within the Non-Guarantors column.

Commitments and Contingencies	'
	(8) Commitments and Contingencies
	a.
	Litigation—General
	We are involved in litigation from time to time in the ordinary course of business. A portion of the defense and/or settlement costs associated with such litigation is covered by various commercial liability insurance policies purchased by us and, in limited cases, indemnification from third parties. Our policy is to establish reserves for loss contingencies when the losses are both probable and reasonably estimable. We record legal costs associated with loss contingencies as expenses in the period in which they are incurred. The matters described below represent our significant loss contingencies. We have evaluated each matter and, if both probable and estimable, accrued an amount that represents our estimate of any probable loss associated with such matter. In addition, we have estimated a reasonably possible range for all loss contingencies including those described below. We believe it is reasonably possible that we could incur aggregate losses in addition to amounts currently accrued for all matters up to an additional $43,000 over the next several years.
	b.
	Government Contract Billing Matter
	Since October 2001, we have provided services to the U.S. Government under several General Services Administration ("GSA") multiple award schedule contracts (the "Schedules"). From October 1, 2001 through September 30, 2013, we billed approximately $70,600 under the Schedules. The earliest of the Schedules was renewed in October 2006 with certain modifications to its terms. 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 U.S. Government sent us a subpoena seeking information that substantially overlaps with the subjects that are covered by the voluntary disclosure process that we initiated with the GSA and OIG in June 2011, except that the subpoena seeks information dating back to 2000, including the initial GSA schedule period of 2001 to 2006, and seeks information about non-GSA federal and state and local customers. Despite the substantial overlap, we understand that the subpoena relates to a separate inquiry, under the civil False Claims Act, that has been initiated independent of the GSA and OIG voluntary disclosure matter.
	We continue to review this matter and provide the U.S. Government with information, including pricing practices and the proposed pricing adjustment amount to be refunded. The U.S. Government, however, may not agree with our determination of the refund amount and may request additional pricing adjustments, refunds, civil penalties, up to treble damages and/or interest.
	Given the above, it is reasonably possible that an adjustment to our estimates may be required in the future as a result of updated facts and circumstances. To the extent that an adjustment to our estimates is necessary in a future period, we will assess, at that time, whether the adjustment is a result of a change in estimate or the correction of an error. A change in estimate would be reflected as an adjustment through the then-current period statement of operations. A correction of an error would require a quantitative and qualitative analysis to determine the approach to correcting the error. A correction of an error could be reflected in the then-current period statement of operations or as a restatement of prior period financial information, depending upon the underlying facts and circumstances and our quantitative and qualitative analysis.
	c.
	State of Massachusetts Assessment
	During the third quarter of 2012, we applied for an abatement of assessments from the state 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. We intend to defend this matter vigorously at the Massachusetts Appellate Tax Board. 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. We intend to file a petition with the Massachusetts Appellate Tax Board to challenge the assessment for the 2007 and 2008 tax years and will vigorously defend the matter. Additionally, the state has begun an audit of the 2009-2011 tax years.
	d.
	Italy Fire
	On November 4, 2011, we experienced a fire at a facility we leased in Aprilia, Italy. The facility primarily stored archival and inactive business records for local area businesses. Despite quick response by local fire authorities, damage to the building was extensive, and the building and its contents were a total loss. We continue to assess the impact of the fire, and, 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 three customers, and have 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 and cash flows. As discussed in Note 10, 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 statement of operations and proceeds received within cash flows from operating activities in our consolidated statement 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, net within operating income in our consolidated statement of operations and proceeds received within cash flows from investing activities within our consolidated statement 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 operation and cash flow impacts related to the fire will be reflected as discontinued operations.

	Our board of directors has authorized up to $1,200,000 in repurchases of our common stock. All repurchases are subject to stock price, market conditions, corporate and legal requirements and other factors. As of September 30, 2013, we had a remaining amount available for repurchase under our share repurchase program of $66,035, which represents approximately 1% in the aggregate of our outstanding common stock based on the closing stock price on such date.
	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 2012 and in the first nine months of 2013, our board of directors declared the following dividends:

	On October 11, 2012, we announced the declaration by our board of directors of a special dividend of $700,000 (the "Special Dividend"), payable, at the election of the stockholders, in either common stock or cash to stockholders of record as of October 22, 2012 (the "Record Date"). The Special Dividend, which is a distribution to stockholders of a portion of our accumulated earnings and profits, was paid in a combination of common stock and cash. The Special Dividend was paid on November 21, 2012 (the "Distribution Date") to stockholders as of the Record Date. Stockholders elected to be paid their pro rata portion of the Special Dividend in all common stock or cash. The total amount of cash paid to all stockholders associated with the Special Dividend was approximately $140,000 (including cash paid in lieu of fractional shares). Our shares of common stock were valued for purposes of the Special Dividend based upon the average closing price on the three trading days following November 14, 2012, or $32.87 per share, and as such, the number of shares of common stock we issued in the Special Dividend was approximately 17,000,000 and the total amount of common stock paid to all stockholders associated with the Special Dividend was approximately $560,000. These shares impact weighted average shares outstanding from the date of issuance, thus impacting our earnings per share data prospectively from the Distribution Date.

Goodwill and Other Intangible Assets	'
	d.
	Goodwill and Other Intangible Assets
	Goodwill and intangible assets with indefinite lives are not amortized but are reviewed annually for impairment or more frequently if impairment indicators arise. Other than goodwill, we currently have no intangible assets that have indefinite lives and which are not amortized. Separable intangible assets that are not deemed to have indefinite lives are amortized over their useful lives. We annually assess whether a change in the life over which our intangible assets are amortized is necessary or more frequently if events or circumstances warrant.
	We have selected October 1 as our annual goodwill impairment review date. We performed our most recent annual goodwill impairment review as of October 1, 2012 and noted no impairment of goodwill at such date. As of December 31, 2012 and September 30, 2013, no factors were identified that would alter our October 1, 2012 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, 2012 were as follows: (1) North America; (2) United Kingdom, Ireland, Norway, Belgium, France, Germany, Luxembourg, Netherlands and Spain ("Western Europe"); (3) the remaining countries in Europe, excluding Russia and Ukraine, in which we operate ("Emerging Markets"); (4) Latin America; (5) Australia, China, Hong Kong and Singapore ("Asia Pacific"); and (6) India, Russia and Ukraine ("Emerging Market Joint Ventures"). As of December 31, 2012, the carrying value of goodwill, net amounted to $1,762,307, $365,303, $87,492, $56,893 and $62,764 for North America, Western Europe, Emerging Markets, Latin America and Asia Pacific, respectively. Our Emerging Market Joint Ventures reporting unit had no goodwill as of December 31, 2012 and September 30, 2013. Based on our goodwill impairment assessment, all of our reporting units with goodwill had estimated fair values as of October 1, 2012 that exceeded their carrying values by greater than 30%. As of September 30, 2013, the carrying value of goodwill, net amounted to $1,764,736, $368,240, $87,322, $99,457 and $56,326 for North America, Western Europe, Emerging Markets, Latin America and Asia Pacific, respectively.
	Reporting unit valuations have been calculated using an income approach based on the present value of future cash flows of each reporting unit or a combined approach based on the present value of future cash flows and market and transaction 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 nine months ended September 30, 2013 are as follows:
		North			International			Total
		American			Business			Consolidated

	Total fair value and other adjustments primarily include $(143) in net adjustments to property, plant and equipment, net, customer relationships and deferred income taxes made within one year from the date of the acquisition, as well as $74 of cash received related to acquisitions made in previous years.
	The components of our amortizable intangible assets as of September 30, 2013 are as follows:
		Gross Carrying			Accumulated			Net Carrying
		Amount			Amortization			Amount
	Customer Relationships and Acquisition Costs	$	749,818		$	(261,510	)	$	488,308

	Amortization expense associated with amortizable intangible assets (including deferred financing costs) was $12,128 and $31,335 for the three and nine months ended September 30, 2012, respectively. Amortization expense associated with amortizable intangible assets (including deferred financing costs) was $10,404 and $33,393 for the three and nine months ended September 30, 2013, respectively.
Stock-Based Compensation	'
	e.
	Stock-Based Compensation
	We record stock-based compensation expense, utilizing the straight-line method, for the cost of stock options, restricted stock, restricted stock units, performance units and shares of stock issued under the 2003 employee stock purchase plan (together, "Employee Stock-Based Awards").
	Stock-based compensation expense for Employee Stock-Based Awards included in the accompanying Consolidated Statements of Operations for the three and nine months ended September 30, 2012 was $4,682 ($3,836 after tax or $0.02 per basic and diluted share) and $20,799 ($15,744 after tax or $0.09 per basic and diluted share), respectively. Stock-based compensation expense for Employee Stock-Based Awards for the three and nine months ended September 30, 2013 was $9,423 ($6,590 after tax or $0.03 per basic and diluted share) and $23,016 ($17,576 after tax or $0.09 per basic and diluted share), respectively.
	Stock-based compensation expense for Employee Stock-Based Awards included in the accompanying Consolidated Statements of Operations related to continuing operations is as follows:
		Three Months						Nine Months Ended
		Ended						September 30,
		September 30,
		2012			2013			2012			2013
	Cost of sales (excluding depreciation and amortization)	$	329		$	115		$	846		$	257
	Selling, general and administrative expenses		4,353			9,308			19,953			22,759
	Total stock-based compensation	$	4,682		$	9,423		$	20,799		$	23,016
	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 $309 and $2,499 for the nine months ended September 30, 2012 and 2013, respectively, from the benefits of tax deductions in excess of 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 were granted with exercise prices equal to 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 September 30, 2013, ten-year vesting options represented 10.4% of total outstanding options. Beginning in 2011, 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 September 30, 2013, three-year vesting options represented 20.3% 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.
	The weighted average fair value of options granted for the nine months ended September 30, 2012 and 2013 was $7.00 and $7.69 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 respective period:
		Nine Months Ended
		September 30,
	Weighted Average Assumptions	2012			2013
	Expected volatility		33.8	%		33.8	%
	Risk-free interest rate		1.24	%		1.13	%
	Expected dividend yield		3	%		3	%
	Expected life		6.3 years			6.3 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 U.S. 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 our employees.

	Restricted Stock and Restricted Stock Units
	Under our various stock option plans, we may also issue grants of restricted stock or restricted stock units ("RSUs"). Our restricted stock and RSUs generally have a three- to five-year vesting period from the date of grant. As a result of an amendment to our RSUs approved by our Compensation Committee of our board of directors in October 2012, all RSUs now 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 $8 and $42 of cash dividends on RSUs for the three and nine months ended September 30, 2012, respectively. We accrued approximately $378 and $1,476 of cash dividends on RSUs for the three and nine months ended September 30, 2013, respectively. There were no cash dividends paid on RSUs for the three and nine months ended September 30, 2012, respectively. We paid approximately $121 and $674 of cash dividends on RSUs for the three and nine months ended September 30, 2013, 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 nine months ended September 30, 2013 is as follows:
		Restricted			Weighted-
		Stock and RSUs			Average
					Grant-Date

	Forfeited		(54,458	)		29.95
	Non-vested at September 30, 2013		1,413,089		$	32.33
	The total fair value of restricted stock vested during each of the three months ended September 30, 2012 and 2013 was $0. The total fair value of restricted stock vested during each of the nine months ended September 30, 2012 and 2013 was $1. The total fair value of RSUs vested during the nine months ended September 30, 2012 was $5,962. The total fair value of RSUs vested during the three and nine months ended September 30, 2013 was $2,145 and $14,221, respectively.
	Performance Units
	Under our various equity compensation plans, we may also make awards of performance units ("PUs"). For the majority of PUs, the number of PUs earned is determined based on our performance against predefined calendar year targets of revenue growth and return on invested capital ("ROIC"). The number of PUs earned may range from 0% to 150% of the initial award. The number of PUs earned is determined based on the Company's actual performance as compared to the targets at the end of the one-year performance period. Certain PUs granted in 2013 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. 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 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. As a result of an amendment to our PUs approved by our Compensation Committee of our board of directors in October 2012, outstanding PUs now 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 $146 and $535 of cash dividends on PUs for the three and nine months ended September 30, 2013, respectively.
	During the nine months ended September 30, 2013, we issued 198,869 PUs. For PUs that are earned based on our performance against revenue growth and ROIC targets during the one-year performance period, we forecast the likelihood of achieving the predefined annual 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 one-year performance period) or the actual PUs earned (at the one-year anniversary date) over the vesting period for each of the awards. For the 2013 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 nine months ended September 30, 2012 was $3,505. The total fair value of earned PUs that vested during the nine months ended September 30, 2013 was $996. There were no cash dividends paid on PUs for both the three and nine months ended September 30, 2012 and 2013. As of September 30, 2013, we expected 87.0% achievement of the predefined revenue and ROIC targets associated with the awards of PUs made in 2013.

Employee Stock Purchase Plan
We offer an employee stock purchase plan (the "ESPP") in which participation is available to substantially all U.S. 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 cost for the ESPP shares purchased. For the nine months ended September 30, 2012 and 2013, there were 88,672 shares and 74,732 shares, respectively, purchased under the ESPP. The number of shares available for purchase under the ESPP at September 30, 2013 was 204,494. We anticipate that the ESPP will be replaced subsequent to the expiration of our June 1 offering on November 29, 2013, by the Iron Mountain Incorporated 2013 Employee Stock Purchase Plan, which was approved by our stockholders at the 2013 Annual Meeting of Stockholders held on June 6, 2013. We anticipate that beginning November 29, 2013, we will have 1,000,000 shares available under the ESPP.
As of September 30, 2013, unrecognized compensation cost related to the unvested portion of our Employee Stock-Based Awards was $50,735 and is expected to be recognized over a weighted-average period of 2.1 years.
We generally issue shares of our common stock for the exercises of stock options, restricted stock, RSUs, PUs and shares of our common stock under our ESPP from unissued reserved shares.
Income (Loss) Per Share-Basic and Diluted	'
	f.
	Income (Loss) Per Share—Basic and Diluted
	Basic income (loss) per common share is calculated by dividing income (loss) by the weighted average number of common shares outstanding. The calculation of diluted income (loss) per share is consistent with that of basic income (loss) per share but gives effect to all potential common shares (that is, securities such as options, warrants or convertible securities) that were outstanding during the period, unless the effect is antidilutive.

Revenues	'
	g.
	Revenues
	Our revenues consist of storage rental revenues as well as service revenues and are reflected net of sales and value added taxes. Storage rental revenues, which are considered a key driver of financial performance for the storage and information management services industry, consist primarily of recurring periodic rental charges related to the storage of materials or data (generally on a per unit basis). Service revenues include charges for related core service activities and a wide array of complementary products and services. Included in core service revenues are: (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 (4) other recurring services, including Document Management Solutions, which relate to physical and digital records, and recurring project revenues. Our complementary services revenues include special project work, customer termination and permanent withdrawal fees, data restoration projects, fulfillment services, consulting services, technology services and product sales (including specially designed storage containers and related supplies). Our secure shredding revenues include the sale of recycled paper (included in complementary services revenues), the price of which can fluctuate from period to period, adding to the volatility and reducing the predictability of that revenue stream.
	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 is included as a component of service revenues, is recognized when products are shipped and title has passed to the customer. Revenues from the sales of products have historically not been significant.
Allowance for Doubtful Accounts and Credit Memo Reserves	'
	h.
	Allowance for Doubtful Accounts and Credit Memo Reserves
	We maintain an allowance for doubtful accounts and credit memos for estimated losses resulting from the potential inability of our customers to make required payments and potential disputes regarding billing and service issues. When calculating the allowance, we consider our past loss experience, current and prior trends in our aged receivables and credit memo activity, current economic conditions and specific circumstances of individual receivable balances. If the financial condition of our customers were to significantly change, resulting in a significant improvement or impairment of their ability to make payments, an adjustment of the allowance may be required. We consider accounts receivable to be delinquent after such time as reasonable means of collection have been exhausted. We charge-off uncollectible balances as circumstances warrant, generally, no later than one year past due.
Income Taxes	'
	i.
	Income Taxes
	Our effective tax rates for the three and nine months ended September 30, 2012 were 36.7% and 40.3%, respectively. Our effective tax rates for the three and nine months ended September 30, 2013 were 81.5% and 63.4%, respectively. The primary reconciling items between the federal statutory rate of 35% and our overall effective tax rate 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), and the planned repatriation discussed below. During the three and nine months ended September 30, 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 5.6% and 1.2%, respectively. During the three months ended September 30, 2013, foreign currency gains were recorded in lower tax jurisdictions associated with our marking-to-market of intercompany loans while foreign currency losses were recorded in higher tax jurisdictions associated with our marking-to-market of debt and derivative instruments, which decreased our 2013 effective tax rate by 47.0%. During the three and nine months ended September 30, 2013, the planned repatriation discussed below increased our 2013 effective tax rate by 87.1% and 18.5%, respectively. Also, during the three and nine months ended September 30, 2013, we incurred non-deductible transaction costs related to our potential conversion to a REIT, which increased our 2013 effective tax rate by 10.1% and 4.7%, respectively.
	On January 2, 2013, the American Taxpayer Relief Act of 2012 (the "ATRA") was signed into law. In part, the ATRA retroactively reinstated and extended the controlled foreign corporation look-through rule, which provides for the exception from January 1, 2012 to December 31, 2013 of certain foreign earnings from U.S. federal taxation as Subpart F income. As a result, our income tax provision for the first quarter of 2013 included a discrete tax benefit of $4,025 relating to the previously expired period from January 1, 2012 to December 31, 2012.
	On September 13, 2013, the Internal Revenue Service released final tangible property regulations under Sections 162(a) and 263(a) of the Internal Revenue Code of 1986 (the "Code"), regarding the deduction and capitalization of expenditures related to tangible property. The final regulations replace temporary regulations that were issued in December 2011. Also released were proposed regulations under Section 168 of the Code regarding dispositions of tangible property. These final and proposed regulations will be effective for our tax year beginning on January 1, 2014. Early adoption is available, and as such, we intend to elect early adoption of the regulations. Changes for tax treatment elected by us or required by the regulations will generally be effective prospectively; however, implementation of many of the regulations' provisions will require a calculation of the cumulative effect of the changes on prior years, and it is expected that such amount will have to be included in the determination of our taxable income over a four-year period beginning in 2013. Transition guidance providing the procedural rules to comply with such regulations is expected to be released in the near term. We do not believe these regulations will have a material impact on our consolidated results of operations, cash flows and financial position.
	We provide for income taxes during interim periods based on our estimate of the effective tax rate for the year. Discrete items and changes in our estimate of the annual effective tax rate are recorded in the period they occur. Our effective tax rate is subject to variability in the future due to, among other items: (1) changes in the mix of income from foreign jurisdictions; (2) tax law changes; (3) volatility in foreign exchange gains (losses); (4) the timing of the establishment and reversal of tax reserves; (5) our ability to utilize foreign tax credits and net operating losses that we generate; and (6) our proposed conversion to a real estate investment trust ("REIT"). We are subject to income taxes in the U.S. and numerous foreign jurisdictions. We are subject to examination by various tax authorities in jurisdictions in which we have business operations or a taxable presence. We regularly assess the likelihood of additional assessments by tax authorities and provide for these matters as appropriate. Although we believe our tax estimates are appropriate, the final determination of tax audits and any related litigation could result in changes in our estimates.
	Accounting for income taxes requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the tax and financial reporting basis of assets and liabilities and for loss and credit carryforwards. Valuation allowances are provided when recovery of deferred tax assets does not meet the more likely than not standard as defined in GAAP.
	We have elected to recognize interest and penalties associated with uncertain tax positions as a component of the provision (benefit) for income taxes in the accompanying Consolidated Statements of Operations. We recorded an increase of $922 and $920 for gross interest and penalties for the three and nine months ended September 30, 2012, respectively. We recorded an increase of $1,014 and $1,735 for gross interest and penalties for the three and nine months ended September 30, 2013, respectively. We had $3,554 and $5,225 accrued for the payment of interest and penalties as of December 31, 2012 and September 30, 2013, respectively.
	During the three months ended September 30, 2013, we developed a plan to utilize both current and carryforward foreign tax credits by repatriating approximately $253,000 (approximately $53,000 of which we had previously paid U.S. 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. We anticipate completing this plan in the fourth quarter of 2013. As a result, we recorded an increase in our tax provision from continuing operations in the amount of approximately $71,400 in the three months ended September 30, 2013. This increase was offset by decreases of approximately $23,500 from current year foreign tax credits and approximately $21,900 reversal of valuation allowances related to foreign tax credit carryforwards, resulting in a net increase of approximately $26,000 in our tax provision from continuing operations.
	After the planned repatriation, we will have a net tax over book outside basis difference related to our foreign subsidiaries. We do not expect this net basis difference to reverse in the foreseeable future and we intend to reinvest any future undistributed earnings of certain foreign subsidiaries indefinitely outside the U.S. We have instances where we have book over tax outside basis differences for certain foreign subsidiaries. These basis differences arose primarily through the undistributed book earnings of such foreign subsidiaries. These basis differences could be reversed through a sale of such foreign subsidiaries, the receipt of dividends from such subsidiaries or certain other events or actions on our part, each of which would result in an increase in our provision for income taxes. It is not practicable to calculate the amount of unrecognized deferred tax liability on these book over tax outside basis difference because of the complexities of the hypothetical calculation. We may record additional deferred taxes on book over tax outside basis differences related to certain foreign subsidiaries in the future depending upon a number of factors, decisions and events in connection with our potential conversion to a REIT, including favorable indications from the U.S. Internal Revenue Service with regard to our private letter ruling requests, finalization of countries to be included in our plan to convert to a REIT, shareholder approval of certain modifications to our corporate charter and final board of director approval of our conversion to a REIT.
	As of September 30, 2013, we have reclassified approximately $27,500 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 recharacterization of certain racking structures as real estate rather than personal property and amortization associated with other intangible assets in conjunction with our potential conversion to a REIT.
Property, Plant and Equipment and Long-Lived Assets	'
	o.
	Property, Plant and Equipment and Long-Lived Assets
	We develop various software applications for internal use. Computer software costs associated with internal use software are expensed as incurred until certain capitalization criteria are met. Payroll and related costs for employees directly associated with, and devoting time to, the development of internal use computer software projects (to the extent time is spent directly on the project) are capitalized. 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. Depreciation begins when the software is placed in service. Computer software costs that are capitalized are periodically evaluated for impairment.
	We review long-lived assets and all amortizable intangible assets for impairment whenever events or changes in circumstances indicate the carrying amount of such assets may not be recoverable. Recoverability of these assets is determined by comparing the forecasted undiscounted net cash flows of the operation to which the assets relate to their carrying amount. The operations are generally distinguished by the business segment and geographic region in which they operate. If the operation is determined to be unable to recover the carrying amount of its assets, then intangible assets are written down first, followed by the other long-lived assets of the operation, to fair value. Fair value is determined based on discounted cash flows or appraised values, depending upon the nature of the assets.
	Consolidated gain on disposal/write-down of property, plant and equipment, net was $173 and $2,375 for the three and nine months ended September 30, 2013, respectively, and consisted primarily of gains on the retirement of leased vehicles accounted for as capital lease assets associated with our North American Business segment and the sale of a building in the United Kingdom. Consolidated gain on disposal/write-down of property, plant and equipment, net was $1,515 for the nine months ended September 30, 2012 and consisted primarily of approximately $2,700 of gains associated with the sale of leased vehicles in North America, partially offset by approximately $700 of asset write-offs in North America and approximately $500 of asset write-offs associated with our Latin America operations.
