Nature of Business and Summary of Significant Accounting Policies

Nature of Business

Equinix, Inc. (“Equinix” or the “Company”) was incorporated in Delaware on June 22, 1998. Equinix provides colocation space and related services. Global enterprises, content providers, financial companies and network service providers rely upon Equinix’s insight and expertise to safehouse and connect their most valued information assets. The Company operates International Business Exchange (“IBX”) data centers, or IBX data centers, across 32 markets in the Americas; Europe, Middle East and Africa (“EMEA”) and Asia-Pacific geographic regions where customers directly interconnect with a network ecosystem of partners and customers. More than 975 network service providers offer access to the world’s Internet routes inside the Company’s IBX data centers. This access to Internet routes provides Equinix customers improved reliability and streamlined connectivity while significantly reducing costs by reaching a critical mass of networks within a centralized physical location.

In September 2012, the Company announced that its board of directors approved a plan to pursue conversion to a real estate investment trust (“REIT”) (the “REIT Conversion”). The Company plans to make a tax election for REIT status for the taxable year beginning January 1, 2015.

Basis of Presentation, Consolidation and Foreign Currency

The accompanying consolidated financial statements include the accounts of Equinix and its subsidiaries, including the acquisition of Frankfurt Kleyer 90 Carrier Hotel from October 1, 2013, the alliance with Emirates Integrated Telecommunications Company PJSC (“du”) from November 9, 2012, the acquisitions of Asia Tone Limited (“Asia Tone”) from July 4, 2012, ancotel GmbH (“ancotel”) from July 3, 2012 and ALOG Data Centers do Brasil S.A. and its subsidiaries (“ALOG”) from April 25, 2011. All significant intercompany accounts and transactions have been eliminated in consolidation. Foreign exchange gains or losses resulting from foreign currency transactions, including intercompany foreign currency transactions, that are anticipated to be repaid within the foreseeable future, are reported within other income (expense) on the Company’s accompanying consolidated statements of operations. For additional information on the impact of foreign currencies to the Company’s consolidated financial statements, see “Accumulated Other Comprehensive Income (Loss)” in Note 12 below.

Reclassifications

Certain amounts in the accompanying consolidated financial statements have been reclassified to conform to the consolidated financial statement presentation as of and for the year ended December 31, 2013.

Use of Estimates

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the U.S. requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. On an ongoing basis, the Company evaluates its estimates, including, but not limited to, those related to the allowance for doubtful accounts, fair values of financial instruments, intangible assets and goodwill, useful lives of intangible assets and property, plant and equipment, assets acquired and liabilities assumed from acquisitions, asset retirement obligations, restructuring charges, redemption value of redeemable non-controlling interests and income taxes. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable.

Assets and liabilities to be disposed of that meet all of the criteria to be classified as held for sale as set forth in the accounting standard for impairment or disposal of long-lived assets are reported at the lower of their carrying amounts or fair values less costs to sell. Assets are not depreciated or amortized while they are classified as held for sale. Assets and liabilities held for sale that have operations and cash flows that can be clearly distinguished, operationally and for financial reporting purposes, from the rest of the Company’s assets and liabilities are reported in discontinued operations when (a) it is determined that the operations and cash flows will be eliminated from the Company’s continuing operations and (b) the Company will not have any significant continuing involvement in the operations of the assets and liabilities after the disposal transaction.

The Company’s consolidated statements of operations have been reclassified to reflect its discontinued operations for all periods presented. For further information on the Company’s discontinued operations, see Note 5.

Cash, Cash Equivalents and Short-Term and Long-Term Investments

The Company considers all highly liquid instruments with an original maturity from the date of purchase of three months or less to be cash equivalents. Cash equivalents consist of money market mutual funds and highly liquid debt securities of corporations, certificates of deposit and commercial paper with original maturities up to 90 days. Short-term investments generally consist of securities with original maturities of between 90 days and one year and are money market mutual funds, highly liquid debt securities of corporations, agencies of the U.S. government and the U.S. government, asset-backed securities, commercial paper and certificates of deposit. Long-term investments generally consist of debt securities of corporations, agencies of the U.S. government, the U.S. government, commercial paper and asset-backed securities with maturities greater than 360 days. The Company’s fixed income securities are classified as “available-for-sale” and are carried at fair value with unrealized gains and losses reported in stockholders’ equity as a component of other comprehensive income. The cost of securities sold is based on the specific identification method. The Company reviews its investment portfolio quarterly to determine if any securities may be other-than-temporarily impaired due to increased credit risk, changes in industry or sector of a certain instrument or ratings downgrades.

Financial Instruments and Concentration of Credit Risk

Financial instruments which potentially subject the Company to concentrations of credit risk consist of cash, cash equivalents and short-term and long-term investments and accounts receivable. Risks associated with cash, cash equivalents and short-term and long-term investments are mitigated by the Company’s investment policy, which limits the Company’s investing to only those marketable securities rated at least A-1/P-1 and A-/A3, as determined by independent credit rating agencies. Risk to the Company’s investment portfolio is further mitigated by its heavy weighting in U.S. government securities.

A significant portion of the Company’s customer base is comprised of businesses throughout the Americas. However, a portion of the Company’s revenues are derived from the Company’s EMEA and Asia-Pacific operations. The following table sets forth percentages of the Company’s revenues by geographic region for the years ended December 31:

2013

2012

2011

Americas

EMEA

Asia-Pacific

No single customer accounted for greater than 10% of accounts receivable or revenues as of or for the years ended December 31, 2013, 2012 and 2011.

Property, Plant and Equipment

Property, plant and equipment are stated at the Company’s original cost or fair value for acquired property, plant and equipment. Depreciation is computed using the straight-line method over the estimated useful lives of the respective assets. Leasehold improvements and assets acquired under capital leases are amortized over the shorter of the lease term or the estimated useful life of the asset or improvement, unless they are considered integral equipment, in which case they are amortized over the lease term. Leasehold improvements acquired in a business combination are amortized over the shorter of the useful life of the assets or a term that includes required lease periods and renewals that are deemed to be reasonably assured at the date of acquisition. Leasehold improvements that are placed into service significantly after and not contemplated at or near the beginning of the lease term are amortized over the shorter of the useful life of the assets or a term that includes required lease periods and renewals that are deemed to be reasonably assured at the date the leasehold improvements are purchased.

The Company’s estimated useful lives of its property, plant and equipment are as follows (in years):

IBX plant and machinery

5 - 30

Leasehold improvements

10 - 40

Buildings (1)

10 - 50

IBX equipment

2.5 - 10

Computer equipment and software

3 - 5

Furniture and fixtures

7 - 10

-1

Includes site improvements.

Effective December 31, 2013, the Company reclassified its site improvements into buildings (see “Property, Plant and Equipment” in Note 6).

During the three months ended December 31, 2012, the Company reassessed the estimated useful lives of certain of its property, plant and equipment as part of a review of the related assumptions. This change was accounted for as a change in accounting estimate on a prospective basis effective October 1, 2012 under the accounting standard for change in accounting estimates. As a result, the Company recorded less depreciation expense for the year ended December 31, 2012, which resulted in the following increases (in thousands, except per share amounts):

Income from operations

4,968

Net income

3,428

Earnings per share:

Basic

0.07

Diluted

0.07

The Company’s construction in progress includes direct and indirect expenditures for the construction and expansion of IBX data centers and is stated at original cost. The Company has contracted out substantially all of the construction and expansion efforts of its IBX data centers to independent contractors under construction contracts. Construction in progress includes costs incurred under construction contracts including project management services, engineering and schematic design services, design development, construction services and other construction-related fees and services. In addition, the Company has capitalized interest costs during the construction phase. Once an IBX data center or expansion project becomes operational, these capitalized costs are allocated to certain property, plant and equipment categories and are depreciated over the estimated useful life of the underlying assets.

Asset Retirement Costs

The fair value of a liability for an asset retirement obligation is recognized in the period in which it is incurred. The associated retirement costs are capitalized and included as part of the carrying value of the long-lived asset and amortized over the useful life of the asset. Subsequent to the initial measurement, the Company accretes the liability in relation to the asset retirement obligations over time and the accretion expense is recorded as a cost of revenue. The Company’s asset retirement obligations are primarily related to its IBX data centers, of which the majority are leased under long-term arrangements, and, in certain cases, are required to be returned to the landlords in their original condition. The majority of the Company’s IBX data center leases have been subject to significant development by the Company in order to convert them from, in most cases, vacant buildings or warehouses into IBX data centers. The majority of the Company’s IBX data centers’ initial lease terms expire at various dates ranging from 2015 to 2053 and most of them enable the Company to extend the lease terms.

Goodwill and Other Intangible Assets

The Company has three reportable segments comprised of the 1) Americas, 2) EMEA and 3) Asia-Pacific geographic regions, which the Company also determined are its reporting units. As of December 31, 2013, the Company had goodwill attributable to its Americas reporting unit, EMEA reporting unit and Asia-Pacific reporting unit.

In September 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2011-08, Testing Goodwill for Impairment. This ASU provides companies with the option to assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If, after assessing the qualitative factors, a company determines that it is not more likely than not that the fair value of a reporting unit is less than its carrying value, then performing the two-step impairment test is unnecessary. However, if a company concludes otherwise, then it is required to perform the first step of the two-step goodwill impairment test. If the carrying value of a reporting unit exceeds its fair value, then a company is required to perform the second step of the two-step goodwill impairment test. This guidance is effective for goodwill impairment tests performed for fiscal years beginning after December 15, 2011, with early adoption permitted. The Company early adopted this standard during the fourth quarter of 2011.

The Company performed the first step of the two-step goodwill impairment test for its Americas reporting unit, EMEA reporting unit and Asia-Pacific reporting unit during the year ended December 31, 2013. In order to determine the fair value of each reporting unit, the Company utilizes the discounted cash flow and market methods. The Company has consistently utilized both methods in its goodwill impairment tests and weighs both results equally. The Company uses both methods in its goodwill impairment tests as it believes both methods, in conjunction with each other, provide a reasonable estimate of the determination of fair value of each reporting unit – the discounted cash flow method being specific to anticipated future results of the reporting unit and the market method, which is based on the Company’s market sector including its competitors. The assumptions supporting the discounted cash flow method, including the discount rate, which was assumed to be 10.0% for the Americas reporting unit and EMEA reporting unit and 13.0% for the Asia-Pacific reporting unit, was determined using the Company’s best estimates as of the date of the impairment review. As of November 30, 2013, the Company concluded that its goodwill attributed to the Company’s Americas reporting unit, EMEA reporting unit and Asia-Pacific reporting unit was not impaired as the fair value of each reporting unit substantially exceeded the carrying value of its respective reporting unit, including goodwill. In addition, the Company concluded that no events occurred or circumstances changed subsequent to November 30, 2013 through December 31, 2013 that would more likely than not reduce the fair value of the Americas, EMEA and Asia-Pacific reporting units below its carrying value. The Company has performed various sensitivity analyses on certain of the assumptions used in the discounted cash flow method, such as forecasted revenues and discount rate, and notes that no reasonably possible changes would reduce the fair value of the reporting unit to such a level that would cause an impairment charge.

Impairment assessments inherently involve judgment as to assumptions about expected future cash flows and the impact of market conditions on those assumptions. Future events and changing market conditions may impact the Company’s assumptions as to prices, costs, growth rates or other factors that may result in changes in the Company’s estimates of future cash flows. Although the Company believes the assumptions it used in testing for impairment are reasonable, significant changes in any one of the Company’s assumptions could produce a significantly different result. Indicators of potential impairment that might lead the Company to perform interim goodwill impairment assessments include significant and unforeseen customer losses, a significant adverse change in legal factors or in the business climate, a significant adverse action or assessment by a regulator, a significant stock price decline or unanticipated competition.

For further information on goodwill and other intangible assets, see Note 6 below.

Derivatives and Hedging Activities

The Company recognizes all derivatives on the consolidated balance sheet at fair value. The accounting for changes in the value of a derivative depends on whether the contract is for trading purposes or has been designated and qualifies for hedge accounting. In order to qualify for hedge accounting, a derivative must be considered highly effective at reducing the risk associated with the exposure being hedged. In order for a derivative to be designated as a hedge, there must be documentation of the risk management objective and strategy, including identification of the hedging instrument, the hedged item and the risk exposure, and how effectiveness is to be assessed prospectively and retrospectively. Foreign currency gains or losses associated with derivatives that do not qualify for hedge accounting are recorded within other income (expense), net in the Company’s consolidated statements of operations, with the exception of foreign currency embedded derivatives contained in certain of the Company’s customer contracts (see “Revenue Recognition” below), which are recorded within revenues in the Company’s consolidated statements of operations.

To assess effectiveness of derivatives that qualify for hedge accounting, the Company uses a regression analysis. The extent to which a hedging instrument has been and is expected to continue to be effective at achieving offsetting changes in cash flows is assessed and documented at least quarterly. Any ineffectiveness is reported in current-period earnings. If it is determined that a derivative is not highly effective at hedging the designated exposure, hedge accounting is discontinued. For qualifying cash flow hedges, the effective portion of the change in the fair value of the derivative is recorded in other comprehensive income (loss) and recognized in the consolidated statements of operations when the hedged cash flows affect earnings. The ineffective portion of cash flow hedges are immediately recognized in earnings. If the hedge relationship is terminated, then the change in fair value of the derivative recorded in other comprehensive income (loss) is recognized in earnings when the cash flows that were hedged occur, consistent with the original hedge strategy. For hedge relationships discontinued because the forecasted transaction is not expected to occur according to the original strategy, any related derivative amounts recorded in other comprehensive income (loss) are immediately recognized in earnings. The Company does not use derivatives for speculative or trading purposes.

For further information on derivatives and hedging activities, see Note 7 below.

Fair Value of Financial Instruments

The carrying value of the Company’s cash and cash equivalents, short-term and long-term investments represent their fair value, while the Company’s accounts receivable, accounts payable and accrued expenses and accrued property, plant and equipment approximate their fair value due primarily to the short-term maturity of the related instruments. The fair value of the Company’s debt, which is traded in the public debt market, is based on quoted market prices. The fair value of the Company’s debt, which is not publicly traded, is estimated by considering the Company’s credit rating, current rates available to the Company for debt of the same remaining maturities and terms of the debt.

Fair Value Measurements

The Company measures and reports certain financial assets and liabilities at fair value on a recurring basis, including its investments in money market funds and available-for-sale debt investments in other public companies, governmental units and other agencies and derivatives.

The Company also follows the accounting standard for the measurement of fair value for nonfinancial assets and liabilities on a nonrecurring basis. These include:

•

Non-financial assets and non-financial liabilities initially measured at fair value in a business combination or other new basis event, but not measured at fair value in subsequent reporting periods;

•

Reporting units and non-financial assets and non-financial liabilities measured at fair value for goodwill impairment test;

•

Indefinite-lived intangible assets measured at fair value for impairment assessment;

•

Non-financial long-lived assets or asset groups measured at fair value for impairment assessment or disposal;

•

Asset retirement obligations initially measured at fair value but not subsequently measured at fair value; and

•

Non-financial liabilities associated with exit or disposal activities initially measured at fair value but not subsequently measured at fair value.

For further information on fair value measurements, see Note 8 below.

Impairment of Long-Lived Assets

The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable such as a significant decrease in market price of a long-lived asset, a significant adverse change in legal factors or business climate that could affect the value of a long-lived asset or a continuous deterioration of the Company’s financial condition. Recoverability of assets to be held and used is measured by comparing the carrying amount of an asset to estimated undiscounted future net cash flows expected to be generated by the asset. If the carrying amount of the asset exceeds its estimated discounted future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset.

During the year ended December 31, 2012, the Company determined that the fair values of certain long-lived assets in two properties were lower than their carrying values. As a result, the Company recorded impairment charges totaling $9,861,000 in the Americas and Asia-Pacific regions comprised of $7,029,000 of property, plant and equipment and $2,832,000 of intangible assets. The Company did not record any impairment charges related to its long-lived assets during the years ended December 31, 2013 and 2011.

Revenue Recognition

Equinix derives more than 90% of its revenues from recurring revenue streams, consisting primarily of (1) colocation, which includes the licensing of cabinet space and power; (2) interconnection offerings, such as cross connects and Equinix Exchange ports; (3) managed infrastructure services and (4) other revenues consisting of rental income from tenants or subtenants. The remainder of the Company’s revenues are from non-recurring revenue streams, such as from the recognized portion of deferred installation revenues, professional services, contract settlements and equipment sales. Revenues from recurring revenue streams are generally billed monthly and recognized ratably over the term of the contract, generally one to three years for IBX data center space customers. Non-recurring installation fees, although generally paid in a lump sum upon installation, are deferred and recognized ratably over the expected life of the installation. Professional service fees are recognized in the period in which the services were provided and represent the culmination of a separate earnings process as long as they meet the criteria for separate recognition under the accounting standard related to revenue arrangements with multiple deliverables. Revenue from bandwidth and equipment sales is recognized on a gross basis in accordance with the accounting standard related to reporting revenue gross as a principal versus net as an agent, primarily because the Company acts as the principal in the transaction, takes title to products and services and bears inventory and credit risk. To the extent the Company does not meet the criteria for recognizing bandwidth and equipment services as gross revenue, the Company records the revenue on a net basis. Revenue from contract settlements, when a customer wishes to terminate their contract early, is generally recognized on a cash basis, when no remaining performance obligations exist, to the extent that the revenue has not previously been recognized.

The Company occasionally guarantees certain service levels, such as uptime, as outlined in individual customer contracts. To the extent that these service levels are not achieved, the Company reduces revenue for any credits given to the customer as a result. The Company generally has the ability to determine such service level credits prior to the associated revenue being recognized, and historically, these credits have generally not been significant. There were no significant service level credits issued during the years ended December 31, 2013, 2012 and 2011.

Revenue is recognized only when the service has been provided and when there is persuasive evidence of an arrangement, the fee is fixed or determinable and collection of the receivable is reasonably assured. It is the Company’s customary business practice to obtain a signed master sales agreement and sales order prior to recognizing revenue in an arrangement. Taxes collected from customers and remitted to governmental authorities are reported on a net basis and are excluded from revenue.

As a result of certain customer agreements being priced in currencies different from the functional currencies of the parties involved, under applicable accounting rules, the Company is deemed to have foreign currency forward contracts embedded in these contracts. The Company refers to these as foreign currency embedded derivatives (see Note 7). These instruments are separated from their host contracts and held on the Company’s consolidated balance sheet at their fair value. The majority of these foreign currency embedded derivatives arise in certain of the Company’s subsidiaries where the local currency is the subsidiary’s functional currency and the customer contract is denominated in the U.S. dollar. Changes in their fair values are recognized within revenues in the Company’s consolidated statements of operations.

The Company assesses collectability based on a number of factors, including past transaction history with the customer and the credit-worthiness of the customer. The Company generally does not request collateral from its customers although in certain cases the Company obtains a security interest in a customer’s equipment placed in its IBX data centers or obtains a deposit. If the Company determines that collection of a fee is not reasonably assured, the fee is deferred and revenue is recognized at the time collection becomes reasonably assured, which is generally upon receipt of cash. In addition, the Company also maintains an allowance for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments for which the Company had expected to collect the revenues. If the financial condition of the Company’s customers were to deteriorate or if they became insolvent, resulting in an impairment of their ability to make payments, greater allowances for doubtful accounts may be required. Management specifically analyzes accounts receivable and current economic news and trends, historical bad debts, customer concentrations, customer credit-worthiness and changes in customer payment terms when evaluating revenue recognition and the adequacy of the Company’s reserves. A specific bad debt reserve of up to the full amount of a particular invoice value is provided for certain problematic customer balances. An additional reserve is established for all other accounts based on the age of the invoices and an analysis of historical credits issued. Delinquent account balances are written-off after management has determined that the likelihood of collection is not probable.

Income Taxes

Income taxes are accounted for under the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the year in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts that are expected more likely than not to be realized in the future. A tax benefit from an uncertain income tax position may be recognized in the financial statements only if it is more likely than not that the position is sustainable, based solely on its technical merits and consideration of the relevant taxing authority’s widely understood administrative practices and precedents.

The REIT conversion, expected to be effective as of January 1, 2015, will not be considered a change in tax status for the Company’s U.S. operations. Rather, the effect of the REIT conversion will be reflected in the Company’s consolidated statement of operations in the period that includes the date the Company completes all significant actions necessary to qualify as a REIT, signifying its commitment to that course of action.

The Company recognizes interest and penalties related to unrecognized tax benefits within income tax benefit (expense) in the consolidated statements of operations.

Stock-Based Compensation

Stock-based compensation cost is measured at the grant date for all stock-based awards made to employees and directors based on the fair value of the award and is recognized as expense over the requisite service period, which is generally the vesting period.

The Company grants restricted stock units to its employees and these equity awards generally have only a service condition. The Company grants restricted stock units to its executives and these awards generally have a service and performance condition or a service and market condition. To date, any performance conditions contained in an equity award are tied to the financial performance of the Company or a specific region of the Company. The Company assesses the probability of meeting these performance conditions on a quarterly basis. The majority of the Company’s equity awards vest over four years, although certain of the equity awards for executives vest over a range of two to four years. The valuation of restricted stock units with only a service condition or a service and performance condition requires no significant assumptions as the fair value for these types of equity awards is based solely on the fair value of the Company’s stock price on the date of grant. The Company uses a Monte Carlo simulation option-pricing model to determine the fair value of restricted stock units with a service and market condition.

To the extent that the Company grants stock options to its employees, it uses the Black-Scholes option-pricing model to determine the fair value of stock options. The Company also uses Black-Scholes option-pricing model to determine the fair value of its employee stock purchase plan. The determination of the fair value of stock options or shares purchased under the employee stock purchase plan is affected by assumptions regarding a number of complex and subjective variables including the Company’s expected stock price volatility over the term of the awards and actual and projected employee stock option exercise or purchase behaviors. The Company estimated the expected volatility by using the average historical volatility of its common stock that it believed was the best representative of future volatility. The risk-free interest rate used was based on U.S. Treasury zero-coupon issues with remaining terms similar to the expected term of the equity awards. The expected dividend rate used was zero as the Company did not anticipate paying dividends. The expected term of the equity award used was calculated by taking the average of the vesting or purchase window term and the contractual term of the equity award.

The accounting standard for stock-based compensation does not allow the recognition of unrealized tax benefits associated with the tax deductions in excess of the compensation recorded (excess tax benefit) until the excess tax benefit is realized (i.e., reduces taxes payable). The Company recognizes the benefit from stock-based compensation in equity when the excess tax benefit is realized by following the “with-and-without” approach.

For further information on stock-based compensation, see Note 13 below.

Foreign Currency Translation

The financial position of foreign subsidiaries is translated using the exchange rates in effect at the end of the period, while income and expense items are translated at average rates of exchange during the period. Gains or losses from translation of foreign operations where the local currency is the functional currency are included as other comprehensive income (loss). The net gains and losses resulting from foreign currency transactions are recorded in net income (loss) in the period incurred and reported within other income and expense. Certain inter-company balances are designated as long-term. Accordingly, exchange gains and losses associated with these long-term inter-company balances are recorded as a component of other comprehensive income (loss), along with translation adjustments. How the U.S. dollar performs against certain of the currencies of the foreign countries in which the Company operates can have a significant impact to the Company. Strengthening and weakening of the U.S. dollar against theses currencies has significantly impacted the Company’s consolidated balance sheets (as evidenced in the Company’s foreign currency translation loss), as well as its consolidated statements of operations as amounts denominated in foreign currencies can increase or decrease the Company’s revenues and expenses. To the extent that the U.S. dollar strengthens or weakens further, this will continue to impact the Company’s consolidated balance sheets and consolidated statements of operations including the amount of revenue that the Company reports in future periods.

Earnings Per Share

The Company computes its EPS using the two-class method as prescribed by the accounting standard for earnings per share. The two-class method is an earnings allocation method for computing EPS when an entity’s capital structure includes either two or more classes of common stock or includes common stock and participating securities. The two-class method calculates EPS based on distributed earnings (i.e., adjustments to redeemable non-controlling interests) and undistributed earnings. Undistributed losses are not allocated to participating securities under the two-class method unless the participating security has a contractual obligation to share in losses on a basis that is objectively determinable. Common shares of ALOG (see Note 3) are considered participating securities in which the Company has indirect controlling equity interests.

Basic EPS is computed using net income (loss) attributable to the Company and the weighted-average number of common shares outstanding. Diluted EPS is computed using net income attributable to the Company, adjusted for interest expense as a result of the assumed conversion of the Company’s 2.50% Convertible Subordinated Notes, 3.00% Convertible Subordinated Notes and 4.75% Convertible Subordinated Notes, if dilutive, and the weighted-average number of common shares outstanding plus any dilutive potential common shares outstanding. Dilutive potential common shares include the assumed exercise, vesting and issuance activity of employee equity awards using the treasury stock method, as well as warrants and shares issuable upon the conversion of the 2.50% Convertible Subordinated Notes, 3.00% Convertible Subordinated Notes and 4.75% Convertible Subordinated Notes. The Company computes basic and diluted EPS for net income (loss) attributable to the Company, net income (loss) from continuing operations and net income (loss) from discontinued operations.

Redeemable Non-Controlling Interests

Non-controlling interests in subsidiaries that are redeemable for cash or other assets outside of the Company’s control are classified as mezzanine equity, outside of equity and liabilities, and are adjusted to fair value on each balance sheet date. The resulting changes in fair value of the estimated redemption amount, increases or decreases, are recorded with corresponding adjustments against retained earnings or, in the absence of retained earnings, additional paid-in-capital.

For further information on redeemable non-controlling interests, see Note 11 below.

Treasury Stock

The Company accounts for treasury stock under the cost method. When treasury stock is re-issued at a higher price than its cost, the difference is recorded as a component of additional paid-in capital to the extent that there are gains to offset the losses. If there are no treasury stock gains in additional paid-in capital, the losses are recorded as a component of accumulated deficit.

Recent Accounting Pronouncements

In December 2011, the FASB issued ASU 2011-11, Disclosures about Offsetting Assets and Liabilities. This ASU requires companies to disclose both gross information and net information about instruments and transactions eligible for offset in the statement of financial position and instruments and transactions subject to an agreement similar to a master netting arrangement. In January 2013, the FASB issued ASU 2013-01, clarifying the Scope of Disclosures about Offsetting Assets and Liabilities. This ASU clarifies that the scope of ASU 2011-11 only applies to derivatives accounted for in accordance with ASC 815, Derivatives and Hedging, and securities borrowing and securities lending transactions. This new guidance is effective for interim and annual periods beginning on or after January 1, 2013 and retrospective disclosure is required for all comparative periods presented. During the three months ended March 31, 2013, the Company adopted these ASUs and their adoption did not have a material impact on its consolidated financial statements.

In February 2013, the FASB issued ASU 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. This ASU requires companies to report the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income when applicable or to cross-reference the reclassifications with other disclosures that provide additional detail about the reclassification made when the reclassifications are not made to net income. This ASU is effective for fiscal years and interim periods, beginning after December 15, 2012. During the three months ended March 31, 2013, the Company adopted ASU 2013-02 and the adoption did not have a material impact on its consolidated financial statements since the Company did not have material reclassifications in any periods presented.

In July 2013, the FASB issued ASU 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. This ASU requires companies to present an unrecognized tax benefit, or a portion thereof, as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. To the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, is not available at the reporting date under the applicable tax law or an entity does not intend to use its deferred tax asset for such purpose, the unrecognized tax benefit should be presented as a liability and not a reduction to deferred tax assets. This ASU is effective for fiscal years and interim periods beginning after December 15, 2013 with early adoption permitted. The Company is currently evaluating the impact that the adoption of this standard will have to its consolidated financial statements, if any.

Accounting Changes And Error Corrections [Abstract]	'
Change In Accounting Principle and Revision of Previously-Issued Financial Statements	'
	2	Change In Accounting Principle and Revision of Previously-Issued Financial Statements
	Change in Accounting Principle
	Commencing in 2013, the Company changed its method of accounting for income taxes by excluding the effects of subsequent events that are not recognized in the Company’s consolidated financial statements in determining its estimated annual effective tax rate for interim reporting periods. Prior to the change, the Company’s policy was to include the effects of events that occurred subsequent to the interim balance sheet date in its estimated annual effective tax rate. The Company believes that the change is preferable as it provides consistency with the reporting of activity on a pre-tax basis and aligns with other income tax guidance which requires items such as changes in tax rates to be reflected in the period such laws become effective. In addition, the Company believes this change results in a more comparable method for interim tax accounting with other companies in its industry. This change did not have a significant impact to the Company’s consolidated financial statements as of and for the three months ended March 31, 2012, the three and six months ended June 30, 2012, the three and nine months ended September 30, 2012 and the year ended December 31, 2012 and as a result, the Company did not retrospectively adjust its prior periods’ consolidated financial statements.
	Revision of Previously-Issued Financial Statements
	During the three months ended June 30, 2013, the Company reassessed the estimated period over which revenue related to non-recurring installation fees is recognized as a result of observed trends in customer contract lives. Non-recurring installation fees, although generally paid in a lump sum upon installation, are deferred and recognized ratably over the expected life of the installation. The Company undertook this review due to its determination that its customers were generally benefitting from their installations longer than originally anticipated and, therefore, the estimated period that revenue related to non-recurring installation fees is recognized was extended. This change was originally incorrectly accounted for as a change in accounting estimate on a prospective basis effective April 1, 2013. During the three months ended September 30, 2013, the Company determined that these longer lives should have been identified and utilized for revenue recognition purposes beginning in 2006. As a result, the Company’s installation revenues were overstated by $6,193,000 and $3,460,000 for the years ended December 31, 2012 and 2011, respectively. This error did not impact the Company’s reported total cash flows from operating activities.
	The Company assessed the effect of the above errors, as well as the previously-identified immaterial errors described below, individually and in the aggregate on prior periods’ financial statements in accordance with the SEC’s Staff Accounting Bulletins No. 99 and 108 and, based on an analysis of quantitative and qualitative factors, determined that the errors were not individually material to any of the Company’s prior interim and annual financial statements and, therefore, the previously-issued financial statements could continue to be relied upon and that the amendment of previously filed reports with the SEC was not required. The Company also determined that correction of the cumulative amount of the errors of $27,170,000 as of December 31, 2012 would be material to the projected 2013 consolidated financial statements and as such the Company revised its previously-issued consolidated financial statements.

	As the Company revised its previously-issued consolidated financial statements as described above, as part of the revision the Company also corrected certain previously-identified immaterial errors that were either uncorrected or corrected in a period subsequent to the period in which the error originated including (i) certain recoverable taxes in Brazil that were incorrectly recorded in the Company’s statements of operations, which had the effect of overstating both revenues and cost of revenues; (ii) errors related to certain foreign currency embedded derivatives in Asia-Pacific, which have an effect on revenue; (iii) an error in the Company’s statement of cash flows related to the acquisition of Asia Tone Limited (“Asia Tone”) that affects both cash flows from operating and investing activities; and (iv) errors in depreciation, stock-based compensation and property tax accruals in the U.S.
	All financial information contained in the accompanying footnotes to these consolidation financial statements has been revised to reflect the correction of these errors.
	For the years ended December 31, 2012 and 2011, the Company revised its net income in its consolidated statement of comprehensive income and its consolidated statement of stockholders’ equity and other comprehensive income as a result of the correction of these errors.

	The following table presents the effect of the aforementioned revision on the Company’s consolidated balance sheet as of December 31, 2012 (in thousands):

	3	Acquisitions
	Frankfurt Kleyer 90 Carrier Hotel Acquisition
	On October 1, 2013, the Company completed the purchase of a property located in Frankfurt, Germany for cash consideration of approximately $50,092,000 (the “Frankfurt Kleyer 90 Carrier Hotel Acquisition”). A portion of the building was leased to the Company and was being used by the Company as its Frankfurt 5 IBX data center. The remainder of the building was leased by other parties, who became the Company’s tenants upon closing. The Frankfurt Kleyer 90 Carrier Hotel constitutes a business under the accounting standard for business combinations and as a result, the Frankfurt Kleyer 90 Carrier Hotel Acquisition was accounted for as a business acquisition using the acquisition method of accounting.
	The Company included Frankfurt Kleyer 90 Carrier Hotel’s results of operations from October 1, 2013 and the estimated fair value of assets acquired and liabilities assumed in its consolidated balance sheets beginning October 1, 2013. The Company incurred acquisition costs of approximately $4,794,000 for the year ended December 31, 2013 related to the Frankfurt Kleyer 90 Carrier Hotel Acquisition.
	Purchase Price Allocation
	Under the acquisition method of accounting, the total purchase price was allocated to Frankfurt Kleyer 90 Carrier Hotel’s net tangible and intangible assets based upon their fair value as of the Frankfurt Kleyer 90 Carrier Hotel acquisition date. Based upon the purchase price and the valuation of Frankfurt Kleyer 90 Carrier Hotel, the preliminary purchase price allocation was as follows (in thousands):


	Property, plant and equipment		$	85,969
	Intangible assets			10,011

	Total assets acquired			95,980
	Mortgage payable			(42,906	)
	Intangible - unfavorable leases			(2,982	)

	Net assets acquired		$	50,092

	The Company continues to evaluate certain assets and liability related to the Frankfurt Kleyer 90 Carrier Hotel Acquisition. Additional information, which existed as of the Frankfurt Kleyer 90 Carrier Hotel Acquisition date but was unknown to the Company at the time the Company’s consolidated financial statements were prepared, may become known to the Company during the remainder of the measurement period, a period not to exceed 12 months from the Frankfurt Kleyer 90 Carrier Hotel Acquisition date. Changes to the assets and liabilities recorded may result in a corresponding adjustment to the purchase price allocation.
	The following table presents certain information on the acquired identifiable intangible assets (dollars in thousands):


	Intangible assets		Fair value				Estimated		Weighted-
							useful lives		average
							(years)		estimated
									useful lives
									(years)
	Customer contracts		$	9,363			0.3 - 8		4.9
	Unfavorable leases			(2,982	)		1 - 6		4.8
	Favorable leases			648			1 - 8		7.5
	The fair value of customer contracts was estimated by applying an income approach. The fair value was determined by calculating the present value of estimated future operating cash flows generated by existing customer relationships less costs to realize the revenue. The Company applied a discount rate of approximately 9.0%, which reflects the nature of the assets as it relates to the estimated future operating cash flows. Other significant assumptions used to estimate the fair value of the customer contracts include projected revenue growth, customer attrition rates, sales and marketing expenses and operating margins. The fair value of leases were estimated using the market approach. The fair value measurements were based on significant inputs that are not observable in the market and thus represent Level 3 measurements as defined in the accounting standard for fair value measurements.
	The Company determined the fair value of the mortage payable assumed in the Frankfurt Kleyer 90 Hotel Acquisition by estimating Frankfurt Kleyer 90 Hotel’s debt rating and reviewing market data with a similar debt rating and other characteristics of the debt, including the maturity date and security type.
	For the year ended December 31, 2013, revenues and net income recorded from Frankfurt Kleyer 90 Hotel were not material and were included in the Company’s consolidated statements of operations.

	Dubai IBX Data Center Acquisition
	On November 6, 2012, the Company entered into an alliance agreement with Emirates Integrated Telecommunications Company PJSC (“du”) to deliver data center and interconnection solutions to customers in the Middle East. On November 8, 2012 (the “Dubai IBX Data Center Acquisition Date”), the Company entered into an asset sale and purchase agreement with e-Hosting DataFort FZ, LLC (“EHDF”) for a substantially completed data center located in Dubai for cash consideration of approximately $22,918,000. The data center opened for business in early 2013. The Company also entered into a lease agreement with Tecom Investment FZ, LLC (“Tecom”), the 100% owner of EHDF, for the underlying building space where the data center assets that were acquired by the Company from EHDF are located. The Company accounted for the above agreements as a single arrangement and the alliance agreement, asset sale and purchase agreement and lease agreement are collectively referred to as the Dubai IBX Data Center Acquisition. The Dubai IBX Data Center Acquisition constitutes a business under the accounting standard for business combinations and as a result, the Dubai IBX Data Center Acquisition was accounted for as a business acquisition using the acquisition method of accounting.
	Asia Tone Acquisition
	On July 3, 2012 (the “Asia Tone Acquisition Date”), the Company acquired certain assets and operations of Asia Tone, a privately-owned company headquartered in Hong Kong, for gross cash consideration of $230,500,000 (the “Asia Tone Acquisition”). The Company agreed to pay net cash consideration of approximately $202,445,000 as a result of adjustments to the purchase price included in the purchase and sale agreement. Asia Tone operated six data centers and one disaster recovery center in Hong Kong, Shanghai and Singapore. The Asia Tone Acquisition included one data center under construction in Shanghai at the date of the acquisition. The combined company operates under the Equinix name.
	The Company included Asia Tone’s results of operations from July 4, 2012 and the estimated fair value of assets acquired and liabilities assumed in its consolidated balance sheets beginning July 3, 2012. The Company incurred acquisition costs of $4,887,000 for the year ended December 31, 2012 related to the Asia Tone Acquisition.
	Purchase Price Allocation
	The Asia Tone Acquisition was accounted for using the acquisition method of accounting. Under the acquisition method of accounting, the total purchase price was allocated to Asia Tone’s net tangible and intangible assets based upon their fair value as of the Asia Tone Acquisition Date. Based upon the purchase price and the valuation of Asia Tone, the purchase price allocation was as follows (in thousands):


	Accounts receivable		$	1,595
	Other current assets			595
	Property, plant and equipment			142,450
	Goodwill			115,223
	Intangible assets			29,155
	Other non-current assets			784

	Total assets acquired			289,802
	Accounts payable and accrued expenses			(1,304	)
	Accrued property, plant and equipment			(27,031	)
	Loans payable			(20,661	)
	Capital leases and other financing obligations			(10,630	)
	Other current liabilities			(3,666	)
	Deferred tax liabilities			(15,190	)
	Other non-current liabilities			(8,875	)

	Net assets acquired		$	202,445

	The following table presents certain information on the acquired identifiable intangible assets (dollars in thousands):


Intangible assets		Fair value				Estimated		Weighted-
						useful lives		average
						(years)		estimated
								useful lives
								(years)
Customer contracts		$	14,900			6 - 20		17.2
Customer relationships			13,800			7 - 11		8.7
Other			455			2 - 5		4
The fair value of customer contracts and customer relationships was estimated by applying an income approach. The fair value was determined by calculating the present value of estimated future operating cash flows generated from existing customers less costs to realize the revenue. The Company applied a weighted-average discount rate of approximately 14.4%, which reflected the nature of the assets as it relates to the estimated future operating cash flows. Other significant assumptions used to estimate the fair value of the customer contracts and customer relationships include projected revenue growth, customer attrition rates, sales and marketing expenses and operating margins. The fair value of the other acquired identifiable intangible assets were estimated by applying an income or cost approach as appropriate. The fair value measurements were based on significant inputs that are not observable in the market and thus represent Level 3 measurements as defined in the accounting standard for fair value measurements.
The Company determined the fair value of the loans payable assumed in the Asia Tone Acquisition by estimating Asia Tone’s debt rating and reviewed market data with a similar debt rating and other characteristics of the debt, including the maturity date and security type. The book value of Asia Tone’s loans payable approximated their fair value as of the Asia Tone Acquisition Date. During the year ended December 31, 2012, the Company prepaid and terminated these loans payable.
Goodwill represents the excess of the purchase price over the fair value of the net tangible and intangible assets acquired. The goodwill is not expected to be deductible for local tax purposes. Goodwill will not be amortized and will be tested for impairment at least annually. Goodwill recorded as a result of the Asia Tone Acquisition is attributable to the Company’s Asia-Pacific reportable segment (see Note 17) and reporting unit (see Note 6).
For the year ended December 31, 2012, Asia Tone recognized revenues of $23,083,000 and had a net income of $1,604,000, which were included in the Company’s consolidated statements of operations.
ancotel Acquisition
On July 2, 2012 (the “ancotel Acquisition Date”), the Company acquired 100% of the issued and outstanding share capital of ancotel, a privately-owned company headquartered in Frankfurt, Germany, for cash consideration of approximately $85,714,000 (the “ancotel Acquisition”). ancotel operates one data center in Frankfurt and edge nodes in Hong Kong and London. The combined company operates under the Equinix name.
The Company included ancotel’s results of operations from July 3, 2012 and the estimated fair value of assets acquired and liabilities assumed in its consolidated balance sheets beginning July 2, 2012. The Company incurred acquisition costs of approximately $1,365,000 for the year ended December 31, 2012 related to the ancotel Acquisition.

Purchase Price Allocation
The ancotel Acquisition was accounted for using the acquisition method of accounting. Under the acquisition method of accounting, the total purchase price was allocated to ancotel’s net tangible and intangible assets based upon their fair value as of the ancotel Acquisition Date. Based upon the purchase price and the valuation of ancotel, the purchase price allocation was as follows (in thousands):


Cash and cash equivalents		$	1,478
Accounts receivable			332
Other current assets			2,702
Property, plant and equipment			17,460
Goodwill			55,689
Intangible assets			42,781
Other non-current assets			381

Total assets acquired			120,823
Accounts payable and accrued expenses			(5,310	)
Accrued property, plant and equipment			(1,216	)
Current portion of loans payable			(2,548	)
Capital leases and other financing obligations			(5,516	)
Other current liabilities			(5,035	)
Deferred tax liabilities			(13,280	)
Other non-current liabilities			(2,204	)

Net assets acquired		$	85,714

The following table presents certain information on the acquired identifiable intangible assets (dollars in thousands):

						(years)		estimated
								useful lives
								(years)
Customer contracts		$	38,604			7		7
Trade names			4,177			5 - 10		9.4
The fair value of customer contracts was estimated by applying an income approach. The fair value was determined by calculating the present value of estimated future operating cash flows generated by existing customer relationships less costs to realize the revenue. The Company applied a discount rate of approximately 12.8%, which reflected the nature of the assets as it relates to the estimated future operating cash flows. Other significant assumptions used to estimate the fair value of the customer contracts include projected revenue growth, customer attrition rates, sales and marketing expenses and operating margins. The fair value of trade names were estimated using the income approach. The fair value measurements were based on significant inputs that are not observable in the market and thus represent Level 3 measurements as defined in the accounting standard for fair value measurements.
The Company determined the fair value of the loans payable assumed in the ancotel Acquisition by estimating ancotel’s debt rating and reviewing market data with a similar debt rating and other characteristics of the debt, including the maturity date and security type. The book value of ancotel’s loans payable approximated their fair value as of the ancotel Acquisition Date. During the three months ended September 30, 2012, the Company prepaid and terminated these loans payable.
Goodwill represents the excess of the purchase price over the fair value of the net tangible and intangible assets acquired. The goodwill is not expected to be deductible for local tax purposes. Goodwill will not be amortized and will be tested for impairment at least annually. Goodwill recorded as a result of the ancotel Acquisition is attributable to the Company’s EMEA reportable segment (see Note 17) and reporting unit (see Note 6).
For the year ended December 31, 2012, ancotel recognized revenues of $11,494,000 and had a net loss of $3,281,000, which were included in the Company’s consolidated statements of operations.
ALOG Acquisition
On April 25, 2011 (the “ALOG Acquisition Date”), the Company and RW Brasil Fundo de Investimento em Participações, a subsidiary of Riverwood Capital L.P. (“Riverwood”), completed the acquisition of approximately 90% of the outstanding capital stock of ALOG. As a result, the Company acquired an approximate 53% controlling equity interest in ALOG (the “ALOG Acquisition”). The Company paid a total of approximately 82,194,000 Brazilian reais in cash on the closing date, or approximately $51,723,000, to purchase the ALOG capital stock. An additional 36,000,000 Brazilian reais, or approximately $17,571,000, was payable in April 2013, subject to reduction for any post-closing balance sheet adjustments and any claims for indemnification (the “Contingent Consideration”). During the year ended December 31, 2013, the Company paid a total of 14,255,000 Brazilian reais, or approximately $6,323,000, for the Contingent Consideration. As of December 31, 2013, the Contingent Consideration outstanding was approximately 16,819,000 Brazilian reais, or approximately $7,120,000, of which 8,914,000 Brazilian reais, or approximately $3,774,000, was the Company’s portion. ALOG operated three data centers in Brazil as of the ALOG Acquisition Date and is headquartered in Rio de Janeiro. ALOG will continue to operate under the ALOG trade name. There were no historical transactions between Equinix, Riverwood and ALOG.
Beginning in April 2014 and ending in May 2016, Equinix will have the right to purchase all of Riverwood’s interest in ALOG at a price equal to the greater of (i) its then current fair market value and (ii) a net purchase price that implies a compounded internal rate of return in U.S. dollars (“IRR”) for Riverwood’s investment of 12%. If Equinix exercises its right to purchase Riverwood’s shares, Equinix also will have the right, and under certain circumstances may be required, to purchase the remaining approximate 10% of shares of ALOG that the Company and Riverwood do not own, which are held by ALOG management (collectively, the “Call Options”). If Equinix purchases all of Riverwood’s interest in ALOG at a price equal to its then current fair market value, the purchase price of the remaining approximate 10% of shares that are held by ALOG management will be equal to its then current fair market value. If Equinix purchases all of Riverwood’s interest in ALOG at a net purchase price that implies an IRR for Riverwood’s investment of 12%, the purchase price per share of the remaining approximate 10% of shares that are held by ALOG management will be equal to the greater of (i) 50% of the purchase price per share of capital stock of ALOG in the ALOG Acquisition and (ii) a purchase price per share that implies an IRR equal to the sum of the IRR implied by the fair market value of the capital stock of ALOG plus 2%, declining over time.
Also beginning in April 2014 and ending in May 2016, Riverwood will have the right to require Equinix to purchase all of Riverwood’s interests in ALOG at a price equal to the greater of (i) its then current fair market value and (ii) a net purchase price that implies an IRR for Riverwood’s investment of 8%, declining over time. If Riverwood exercises its right to require Equinix to purchase Riverwood’s shares, Equinix will have the right, and under certain circumstances may be required, to purchase the remaining approximate 10% of shares of ALOG that the Company and Riverwood do not own, which are held by ALOG management (collectively, the “Put Options”). If Equinix purchases all of Riverwood’s interest in ALOG at a price equal to its then current fair market value, the purchase price of the remaining approximate 10% of shares that are held by ALOG management will be equal to its then current fair market value. If Equinix purchases all of Riverwood’s interest in ALOG at a net purchase price that implies an IRR for Riverwood’s investment of 8%, declining over time, the purchase price per share of the remaining approximate 10% of shares that are held by ALOG management will be equal to the greater of (i) 50% of the purchase price per share of capital stock of ALOG in the ALOG Acquisition and (ii) a purchase price per share that implies an IRR equal to the sum of the IRR implied by the fair market value of the capital stock of ALOG plus 2%, declining over time.
As the Company has an approximate 53% controlling equity interest in ALOG, it began consolidating the results of ALOG’s operations on the ALOG Acquisition Date. Upon consolidation, all amounts pertaining to the approximate 10% of ALOG that the Company does not own, as well as Riverwood’s interest in ALOG, are reported as redeemable non-controlling interests in the Company’s consolidated financial statements. The Company included ALOG’s results of operations from April 26, 2011 and the estimated fair value of assets acquired and liabilities assumed in its consolidated balance sheets beginning April 25, 2011. The Company incurred acquisition costs of $2,307,000 for the year ended December 31, 2011 related to ALOG, which were included in the consolidated statements of operations.
Purchase Price Allocation
The ALOG Acquisition was accounted for using the acquisition method of accounting. Under the acquisition method of accounting, the total purchase price was allocated to ALOG’s net tangible and intangible assets based upon their fair value as of the ALOG Acquisition Date with the residual allocated to goodwill. Based upon the purchase price and the valuation of ALOG, the purchase price allocation was as follows (in thousands):


Cash and cash equivalents		$	9,769
Accounts receivable			6,756
Prepaid expense and other current assets			575
Property, plant and equipment			52,542
Goodwill			106,572
Intangible assets			19,295
Other non-current assets			5,214

Total assets acquired			200,723
Accounts payable and accrued expenses			(49,965	)
Debt			(25,669	)
Other current liabilities			(4,643	)
Other non-current liabilities			(1,946	)
Redeemable non-controlling interests			(66,777	)

Net assets acquired		$	51,723

The following table presents certain information on the acquired identifiable intangible assets (dollars in thousands):


Intangible assets		Fair value				Estimated		Weighted-
						useful lives		average
						(years)		estimated
								useful lives
								(years)
Customer contracts		$	17,093			5 - 7		5.9
Other			2,202			3 - 6		4.3
The fair value of customer contracts was estimated by applying an income approach. The fair value was determined by calculating the present value of estimated future operating cash flows generated from exisiting customers less costs to realize the revenue. The Company applied a discount rate of approximately 15.6%, which reflected the nature of the asset as it relates to the estimated future operating cash flows. Other significant assumptions used to estimate the fair value of the customer contracts include projected revenue growth, customer attrition rates, sales and marketing expenses and operating margins. The fair value of the other acquired identifiable intangible assets were estimated by applying an income or cost approach as appropriate. The fair value measurements were based on significant inputs that are not observable in the market and thus represent Level 3 measurements as defined in the accounting standard for fair value measurements.
The Company initially determined the fair value of the loans payable assumed in the ALOG Acquisition by estimating ALOG’s debt rating and reviewed market data with a similar debt rating and other characteristics of the debt, including the maturity date and security type. The Company determined that the book value approximated the fair value as of the ALOG Acquisition Date.

The Company determined the fair value of the redeemable non-controlling interests assumed in the ALOG Acquisition based on the consideration transferred, which included the values ascribed to the Call Options and Put Options. The Company records an adjustment each reporting period to these redeemable non-controlling interests such that the carrying value of the redeemable non-controlling interests equals the greater of fair value or a minimum IRR as outlined in the Put Options.
Goodwill represents the excess of the purchase price over the fair value of the net tangible and intangible assets acquired. Goodwill is attributable to the workforce of ALOG and the significant synergies expected to arise after the ALOG Acquisition. A portion of the goodwill is expected to be deductible for local tax purposes. Goodwill will not be amortized and will be tested for impairment at least annually. Goodwill recorded as a result of the ALOG Acquisition is attributable to the Company’s Americas reportable segment (see Note 17) and reporting unit (see Note 6).
For the year ended December 31, 2011, ALOG recognized revenues of $46,870,000 and had $4,605,000 of net loss, which were included in the Company’s consolidated statements of operations.

	In August 2012, the Company entered into an agreement to sell 16 of the Company’s IBX data centers located throughout the U.S. to an investment group including 365 Main, Crosslink Capital, Housatonic Partners and Brightwood Capital for net proceeds of $76,458,000 (the “Divestiture”). The Divestiture closed in November 2012. Nine of the 16 data centers were in markets that the Company exited with the close of the Divestiture. Those markets include Buffalo, Cleveland, Detroit, Indianapolis, Nashville, Phoenix, Pittsburg, St. Louis and Tampa. The remaining seven data centers were in markets where the Company retains a presence. Those markets include Chicago, Dallas, New York, Philadelphia, Seattle, Silicon Valley and the Washington D.C. metro area. Subsequent to the close of the Divestiture, the investment group runs and manages the 16 IBX Data Centers.

	The Company’s consolidated statements of operations have been reclassified to reflect its discontinued operations associated with the 16 IBX Data Centers for all applicable periods presented. The Company’s operating results from its discontinued operations, which includes the results of operations subsequent to April 30, 2010, the acquisition date of the 16 IBX Data Centers, through November 1, 2012, the closing date of the Divestiture, consisted of the following for the years ended December 31 (in thousands):

	As of December 31, 2013 and 2012, cash and cash equivalents included investments which were readily convertible to cash and had original maturity dates of 90 days or less. The maturities of securities classified as short-term investments were one year or less as of December 31, 2013 and 2012. The maturities of securities classified as long-term investments were greater than one year and less than three years as of December 31, 2013 and 2012.

	None of the securities held at December 31, 2013 were other-than-temporarily impaired.
	While certain marketable securities carry unrealized losses, the Company expects that it will receive both principal and interest according to the stated terms of each of the securities and that the increase or decline in market value is primarily due to changes in the interest rate environment from the time the securities were purchased as compared to interest rates at December 31, 2013.
	The following table summarizes the fair value and gross unrealized losses related to 92 available-for-sale securities, aggregated by type of investment and length of time that individual securities have been in a continuous unrealized loss position, as of December 31, 2013 (in thousands):


			Securities in a loss position							Securities in a loss position

While the Company does not believe it holds investments that are other-than-temporarily impaired and that the Company’s investments will mature at par, the Company’s investments are subject to a low interest rate environment. If market conditions were to deteriorate, the Company could sustain other-than-temporary impairments to its investment portfolio which could result in additional realized losses being recorded in interest income, net or securities markets could become inactive which could affect the liquidity of the Company’s investments.

As of December 31, 2012, the Company’s net unrealized gains (losses) on its available-for-sale securities were comprised of the following (in thousands):

Derivative Instruments And Hedging Activities Disclosure [Abstract]	'
Derivatives and Hedging Instruments	'
	7	Derivatives and Hedging Instruments
	The Company has certain embedded derivatives in its customer contracts. The Company also employs foreign currency forward contracts to partially offset its business exposure to foreign exchange risk for certain existing foreign currency-denominated assets and liabilities and its exposure to foreign currency exchange rate fluctuations for forecasted revenues and expenses in its EMEA region.
	Derivatives Designated as Hedging Instruments
	Cash Flow Hedges. During the fourth quarter of 2013, the Company initiated a program to hedge its exposure to foreign currency exchange rate fluctuations for forecasted revenues and expenses in its EMEA region in order to help manage the Company’s exposure to foreign currency exchange rate fluctuations between the U.S. dollar and the British Pound, Euro and Swiss Franc. The foreign currency forward contracts that the Company uses to hedge this exposure are designated as cash flow hedges under the accounting standard for derivatives and hedging.

	As of December 31, 2013, the Company had a total of 69 cash flow hedge instruments with maturity dates ranging from January 2014 to January 2015 as follows (in thousands):


			Notional			Fair				Accumulated
			amount			value ₍₁₎				other
										comprehensive
										income (loss) ₍₂₎
	Derivative assets		$	127,968		$	2,102			$	2,107
	Derivative liabilities			200,686			(3,855	)			(3,857	)

	Total		$	328,654		$	(1,753	)		$	(1,750	)


	-1	A total of $2,099 and $3 of derivative assets related to cash flow hedges are included in the consolidated balance sheets within other current assets and other assets, respectively. A total of $3,818 and $37 of derivative liabilities related to cash flow hedges are included in the consolidated balance sheets within other current liabilities and other liabilities, respectively.
	-2	Included in the consolidated balance sheets within accumulated other comprehensive income (loss).
	During the year ended December 31, 2013, the ineffective and excluded portions of cash flow hedges recognized in other income (expense) were not significant. During the year ended December 31, 2013, the amount of gains (losses) reclassified from accumulated other comprehensive income (loss) to revenue and operating expenses were not significant. The Company did not enter into any cash flow hedges during the years ended December 31, 2012 and 2011.
	Derivatives Not Designated as Hedging Instruments
	Embedded Derivatives. The Company is deemed to have foreign currency forward contracts embedded in certain of the Company’s customer agreements that are priced in currencies different from the functional or local currencies of the parties involved. These embedded derivatives are separated from their host contracts and carried on the Company’s balance sheet at their fair value. The majority of these embedded derivatives arise as a result of the Company’s foreign subsidiaries pricing their customer contracts in the U.S. dollar.
	The Company has not designated these foreign currency embedded derivatives as hedging instruments under the accounting standard for derivatives and hedging. Gains and losses on these embedded derivatives are included within revenues in the Company’s consolidated statements of operations. During the year ended December 31, 2013, the Company recognized a net gain of $4,836,000 associated with these embedded derivatives. During the years ended December 31, 2012 and 2011, gains (losses) from these embedded derivatives were not significant.
	Economic Hedges of Embedded Derivatives. The Company uses foreign currency forward contracts to help manage the foreign exchange risk associated with the Company’s customer agreements that are priced in currencies different from the functional or local currencies of the parties involved (“economic hedges of embedded derivatives”). Foreign currency forward contracts represent agreements to exchange the currency of one country for the currency of another country at an agreed-upon price on an agreed-upon settlement date.
	The Company has not designated the economic hedges of embedded derivatives as hedging instruments under the accounting standard for derivatives and hedging. Gains and losses on these contracts are included in revenues along with gains and losses of the related embedded derivatives. The Company entered into various economic hedges of embedded derivatives during the year ended December 31, 2013 and recognized a net loss of $4,497,000. The Company did not enter into any economic hedges of embedded derivatives during the years ended December 31, 2012 and 2011.
	Foreign Currency Forward Contracts. The Company also uses foreign currency forward contracts to manage the foreign exchange risk associated with certain foreign currency-denominated assets and liabilities. As a result of foreign currency fluctuations, the U.S. dollar equivalent values of its foreign currency-denominated assets and liabilities change.

	The Company has not designated such foreign currency forward contracts as hedging instruments under the accounting standard for derivatives and hedging. Gains and losses on these contracts are included in other income (expense), net, along with the foreign currency gains and losses of the related foreign currency-denominated assets and liabilities associated with these foreign currency forward contracts. The Company entered into various foreign currency forward contracts during the years ended December 31, 2013 and 2012 and gains (losses) from these foreign currency forward contracts were not significant during these periods.

	The Company did not have any Level 3 financial assets or financial liabilities during the years ended December 31, 2013 and 2012.
	Valuation Methods
	Fair value estimates are made as of a specific point in time based on methods using present value or other valuation techniques. These techniques involve uncertainties and are affected by the assumptions used and the judgments made regarding risk characteristics of various financial instruments, discount rates, estimates of future cash flows, future expected loss experience and other factors.
	Cash, Cash Equivalents and Investments. The fair value of the Company’s investments in money market funds approximates their face value. Such instruments are included in cash equivalents. The Company’s U.S. government securities and money market funds are classified within Level 1 of the fair value hierarchy because they are valued using quoted prices for identical instruments in active markets. The fair value of the Company’s other investments approximate their face value, including certificates of deposit and available-for-sale debt investments related to the Company’s investments in the securities of other public companies, governmental units and other agencies. The fair value of these investments is priced based on the quoted market price for similar instruments or nonbinding market prices that are corroborated by observable market data. Such instruments are classified within Level 2 of the fair value hierarchy. The Company determines the fair values of its Level 2 investments by using inputs such as actual trade data, benchmark yields, broker/dealer quotes, and other similar data, which are obtained from quoted market prices, custody bank, third-party pricing vendors, or other sources. The Company uses such pricing data as the primary input to make its assessments and determinations as to the ultimate valuation of its investment portfolio and has not made, during the periods presented, any material adjustments to such inputs. The Company is responsible for its consolidated financial statements and underlying estimates.

	The Company determined that the major security types held as of December 31, 2013 were primarily cash and money market funds, U.S. government and agency securities, corporate bonds, certificate of deposits, commercial paper and asset-backed securities. The Company uses the specific identification method in computing realized gains and losses. Short-term and long-term investments are classified as available-for-sale and are carried at fair value with unrealized gains and losses reported in stockholders’ equity as a component of other comprehensive income or loss, net of any related tax effect. The Company reviews its investment portfolio quarterly to determine if any securities may be other-than-temporarily impaired due to increased credit risk, changes in industry or sector of a certain instrument or ratings downgrades over an extended period of time.
	During the three months ended March 31, 2013, after reviewing the fair value hierarchy and its valuation criteria, the Company reclassified its U.S. government securities from within Level 2 to Level 1 of the fair value hierarchy because treasury securities issued by the U.S. government are valued using quoted prices for identical instruments in active markets.
	Derivative Assets and Liabilities. For derivatives, including cash flow hedges, embedded derivatives and economic hedges of embedded derivatives, the Company uses forward contract models employing market observable inputs, such as spot currency rates and forward points with adjustments made to these values utilizing published credit default swap rates of its foreign exchange trading counterparties. The Company has determined that the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, therefore the derivatives are categorized as Level 2.
	During the years ended December 31, 2013 and 2012, the Company did not have any nonfinancial assets or liabilities measured at fair value on a recurring basis.

	New York 4 Capital Lease
	In December 2013, the Company entered into a lease amendment for its New York 4 IBX data center (the “New York 4 Lease”) to extend the lease term. The lease was originally accounted for as an operating lease. Pursuant to the accounting standard for leases, the Company reassessed the lease classification of the New York 4 Lease as a result of the lease amendment and determined that the lease should be accounted for as a capital lease (the “New York 4 Capital Lease”). The Company recorded a capital lease asset totaling approximately $23,208,000 and a capital lease liability totaling approximately $24,100,000 during the year ended December 31, 2013. Monthly payments under the New York 4 Capital Lease will be made through September 2036.
	Philadelphia 1 Capital Lease
	In December 2013, the Company entered into a lease amendment for its Philadelphia 1 IBX data center (the “Philadelphia 1 Lease”) to extend the lease term and lease additional space. The lease was originally accounted for as an operating lease. Pursuant to the accounting standard for leases, the Company reassessed the lease classification of the Philadelphia 1 Lease as a result of the lease amendment and determined that the lease should be accounted for as a capital lease (the “Philadelphia 1 Capital Lease”). The Company recorded a capital lease asset totaling approximately $15,366,000 and a capital lease liability totaling approximately $15,430,000 during the three months ended December 31, 2013.

	London IBX Financing
	In November 2013, the Company entered into new leases with the landlord of the Company’s London 4 and London 5 IBX data centers, replacing the existing leases, and through such leases acquired certain rights to the London 4 and London 5 IBX data center buildings and land for an upfront payment of approximately $37,065,000 and payment of on-going rent. Concurrently, the Company entered into a lease agreement for an adjacent parcel of undeveloped land, including the right to construct the Company’s London 6 IBX data center on the land (collectively, the “London IBX Data Centers Expansion”). The total contractual obligation over the estimated term of the three new leases is collectively approximately $235,780,000, excluding the upfront payment, with the remainder to be paid in quarterly installments. The total contractual obligation was allocated to each element of the London IBX Data Centers Expansion based on their relative fair values. The London 4 and London 5 IBX data center leases (collectively, the “London 4 and 5 Leases”) were originally accounted for as financed leases pursuant to the accounting standard for lessee’s involvement in asset construction, since the Company was considered the owner of the buildings due to the building work that the Company undertook. As a result, the Company recorded building assets and related financing liabilities for the buildings, while the underlying ground leases were accounted for as operating leases. As a result of the new leases, the Company accounted for the prepayment of the London 4 and 5 Leases’ financing liabilities as a debt extinguishment and recorded a loss on debt extinguishment (see Note 10) during the three months ended December 31, 2013. The lease for the underlying land where the Company will construct its London 6 IBX data center is accounted for as an operating lease. Quarterly payments under the agreements will be made from December 2013. The Company has certain renewal options available after December 2043, of which one renewal option has been included in the Company’s estimated lease term.
	Digital Realty Capital Leases
	In September 2013, the Company entered into lease amendments with Digital Realty Trust, Inc. to extend the lease term of the Company’s Chicago 1, Dallas 4, Washington D.C. 3, Los Angeles 1 and Miami 2 IBX data centers. The leases were originally accounted for as operating leases, with the exception of the Washington D.C. 3 lease which was originally accounted for as a capital lease. Pursuant to the accounting standard for leases, the Company reassessed the lease classification of the leases as a result of the lease amendments and determined that upon the amendments each of the leases should be accounted for as a capital lease (the “Digital Realty Capital Leases”). The Company recorded incremental capital lease assets totaling approximately $138,826,000 and capital lease liabilities totaling approximately $143,972,000 during the three months ended September 30, 2013.

The Company recorded a capital lease asset totaling approximately $67,346,000 and liability totaling approximately $68,370,000 during the three months ended June 30, 2013.

The total cumulative minimum rent obligation over the term of the lease is approximately $159,040,000, exclusive of renewal periods. The landlord began construction of the building to the Company’s specifications in August 2013.

Operating Leases
The Company currently leases the majority of its IBX data centers and certain equipment under noncancelable operating lease agreements. The majority of the Company’s operating leases for its land and IBX data centers expire at various dates through 2043 with renewal options available to the Company. The lease agreements typically provide for base rental rates that increase at defined intervals during the term of the lease. In addition, the Company has negotiated some rent expense abatement periods for certain leases to better match the phased build out of its IBX data centers. The Company accounts for such abatements and increasing base rentals using the straight-line method over the life of the lease. The difference between the straight-line expense and the cash payment is recorded as deferred rent (see Note 6, “Other Current Liabilities” and “Other Liabilities”).
Minimum future operating lease payments as of December 31, 2013 are summarized as follows (in thousands):

	U.S. Financing
	In June 2012, the Company entered into a credit agreement with a group of lenders for a $750,000,000 credit facility (the “U.S. Financing”), comprised of a $200,000,000 term loan facility (the “U.S. Term Loan”) and a $550,000,000 multicurrency revolving credit facility (the “U.S. Revolving Credit Line”). The U.S. Financing contains several financial covenants with which the Company must comply on a quarterly basis, including a maximum senior leverage ratio covenant, a minimum fixed charge coverage ratio covenant and a minimum tangible net worth covenant. The U.S. Financing is guaranteed by certain of the Company’s domestic subsidiaries and is secured by the Company’s and guarantors’ accounts receivable as well as pledges of the equity interests of certain of the Company’s direct and indirect subsidiaries. The U.S. Term Loan and U.S. Revolving Credit Line both have a five-year term, subject to the satisfaction of certain conditions with respect to the Company’s outstanding convertible subordinated notes. The Company is required to repay the principal balance of the U.S. Term Loan in equal quarterly installments over the term. The U.S. Term Loan bears interest at a rate based on LIBOR or, at the option of the Company, the Base Rate (defined as the highest of (a) the Federal Funds Rate plus 1/2 of 1%, (b) the Bank of America prime rate and (c) one-month LIBOR plus 1.00%) plus, in either case, a margin that varies as a function of the Company’s senior leverage ratio in the range of 1.25%-2.00% per annum if the Company elects to use the LIBOR index and in the range of 0.25%-1.00% per annum if the Company elects to use the Base Rate index. In July 2012, the Company fully utilized the U.S. Term Loan and used the funds to prepay the outstanding balance of and terminate a multi-currency credit facility in the Company’s Asia-Pacific region. The U.S. Revolving Credit Line allows the Company to borrow, repay and reborrow over the term. The U.S. Revolving Credit Line provides a sublimit for the issuance of letters of credit of up to $150,000,000 at any one time. The Company may use the U.S. Revolving Credit Line for working capital, capital expenditures, issuance of letters of credit, and other general corporate purposes. Borrowings under the U.S. Revolving Credit Line bear interest at a rate based on LIBOR or, at the option of the Company, the Base Rate (defined above) plus, in either case, a margin that varies as a function of the Company’s senior leverage ratio in the range of 0.95%-1.60% per annum if the Company elects to use the LIBOR index and in the range of 0.00%-0.60% per annum if the Company elects to use the Base Rate index. The Company is required to pay a quarterly letter of credit fee on the face amount of each letter of credit, which fee is based on the same margin that applies from time to time to LIBOR-indexed borrowings under the U.S. Revolving Credit Line. The Company is also required to pay a quarterly facility fee ranging from 0.30%-0.40% per annum of the U.S. Revolving Credit Line (regardless of the amount utilized), which fee also varies as a function of the Company’s senior leverage ratio. In June 2012, the outstanding letters of credit issued under an existing revolving credit facility were assumed under the U.S. Revolving Credit Line and the existing revolving credit facility was terminated.

	In February 2013, the U.S. Financing was amended to modify certain definitions of items used in the calculation of the financial covenants with which the Company must comply on a quarterly basis to exclude the write-off of any unamortized debt issuance costs that were incurred in connection with the issuance of the 8.125% Senior Notes; to exclude one-time transaction costs, fees, premiums and expenses incurred by the Company in connection with the issuance of the 4.875% Senior Notes and 5.375% Senior Notes and the redemption of the 8.125% Senior Notes; and to exclude the 8.125% Senior Notes from the calculation of total leverage for the period ended March 31, 2013, provided that certain conditions in connection with the redemption of the 8.125% Senior Notes were satisfied. The amendment also postponed the step-down of the maximum senior leverage ratio covenant from the three months ended March 31, 2013 to the three months ended September 30, 2013.
	In September 2013, the U.S. Financing was further amended. Among other changes, the amendment (i) modified certain covenants to accommodate the Company’s planned conversion to a REIT, and related matters; (ii) replaced the maximum senior leverage ratio covenant with a maximum senior net leverage ratio covenant and modified the minimum fixed charge coverage ratio and tangible net worth covenants; (iii) modified certain defined terms used in the calculation of the financial covenants to exclude certain expenses incurred by the Company in connection with its planned REIT conversion; and (iv) permits the Company to request an increase in the U.S. Revolving Credit Line of up to an additional $250,000,000, subject to various conditions including the receipt of lender commitments.
	As of December 31, 2013, the effective interest rate under the U.S. Term Loan was 2.17% per annum. As of December 31, 2013, the Company had 17 irrevocable letters of credit totaling $33,208,000 issued and outstanding under the U.S. Revolving Credit Line. As a result, the amount available to the Company to borrow under the U.S. Revolving Credit Line was $516,792,000 as of December 31, 2013. As of December 31, 2013, the Company was in compliance with all covenants of the U.S. Financing. Debt issuance costs related to the U.S. Financing, net of amortization, were $7,985,000 as of December 31, 2013.

	In November 2013, ALOG completed a 60,318,000 Brazilian real borrowing agreement, or approximately $25,536,000 (the “2013 ALOG Financing”). The 2013 ALOG Financing has a five-year term with semi-annual principal payments beginning in the third year of its term and semi-annual interest payments during the entire term.

	2012 ALOG Financing
	In June 2012, ALOG completed a 100,000,000 Brazilian real borrowing agreement, or approximately $48,807,000 (the “2012 ALOG Financing”). The 2012 ALOG Financing has a five-year term with semi-annual principal payments beginning in the third year of its term and quarterly interest payments during the entire term. The 2012 ALOG Financing bears an interest rate of 2.75% above the local borrowing rate. The 2012 ALOG Financing contains financial covenants, which ALOG must comply with annually, consisting of a leverage ratio and a fixed charge coverage ratio.

During the three months ended September 30, 2012, ALOG fully utilized the 2012 ALOG Financing and used a portion of the funds to prepay and terminate ALOG loans payable outstanding. As of December 31, 2012, the effective interest rate under the 2012 ALOG Financing was 12.52% per annum.

	Mortgage Payable
	In October 2013, as a result of the Frankfurt Kleyer 90 Carrier Hotel Acquisition, the Company assumed a mortgage payable of $42,906,000 (see Note 3) with an effective interest rate of 4.25%. The mortgage payable has monthly principal and interest payments and has an expiration date of August 2022.
	Paris 4 IBX Financing
	In March 2011, the Company entered into two agreements with two unrelated parties to purchase and develop a building that became the Company’s fourth IBX data center in the Paris metro area, which opened for business in August 2012. The first agreement, as amended, allowed the Company the right to purchase the property for a total fee of approximately $19,782,000, payable to a company that held exclusive rights (including power rights) to the property and was already in the process of developing the property into a data center and has, instead, become the anchor tenant in the Paris 4 IBX data center once it opened for business, which occurred in August 2012. The second agreement was entered into with the developer of the property and allowed the Company to take immediate title to the building and associated land and also required the developer to construct the data center to the Company’s specifications and deliver the completed data center to the Company in July 2012 for a total fee of approximately $101,485,000. Of the amounts paid under the Paris 4 IBX Financing, a total of approximately $14,771,000 was allocated to land and building assets, $3,374,000 was allocated to a deferred charge, which is being netted against revenue associated with the anchor tenant of the Paris 4 IBX data center over the term of the customer contract, and the remainder totaling $103,122,000 was allocated to construction costs inclusive of interest charges.
	Convertible Debt
	The Company’s convertible debt consisted of the following as of December 31 (in thousands):


			2013				2012
	3.00% Convertible Subordinated Notes		$	395,986			$	395,986
	4.75% Convertible Subordinated Notes			373,724				373,730

	Less amount representing debt discount			(45,508	)			(60,990	)

			$	724,202			$	708,726

	3.00% Convertible Subordinated Notes
	In September 2007, the Company issued $395,986,000 aggregate principal amount of 3.00% Convertible Subordinated Notes due October 15, 2014 (the “3.00% Convertible Subordinated Notes”). Interest is payable semi-annually on April 15 and October 15 of each year, and commenced April 15, 2008.
	The 3.00% Convertible Subordinated Notes are governed by an Indenture dated as of September 26, 2007, between the Company, as issuer, and U.S. Bank National Association, as trustee (the “3.00% Convertible Subordinated Notes Indenture”). The 3.00% Convertible Subordinated Notes Indenture does not contain any financial covenants or any restrictions on the payment of dividends, the incurrence of senior debt or other indebtedness, or the issuance or repurchase of securities by the Company. The 3.00% Convertible Subordinated Notes are unsecured and rank junior in right of payment to the Company’s existing or future senior debt and equal in right of payment to the Company’s existing and future subordinated debt.

	Holders of the 3.00% Convertible Subordinated Notes may convert their notes at their option on any day up to and including the business day immediately preceding the maturity date into shares of the Company’s common stock. The base conversion rate is 7.436 shares of common stock per $1,000 principal amount of 3.00% Convertible Subordinated Notes, subject to adjustment. This represents a base conversion price of approximately $134.48 per share of common stock. If, at the time of conversion, the applicable stock price of the Company’s common stock exceeds the base conversion price, the conversion rate will be determined pursuant to a formula resulting in the receipt of up to 4.4616 additional shares of common stock per $1,000 principal amount of the 3.00% Convertible Subordinated Notes, subject to adjustment. However, in no event would the total number of shares issuable upon conversion of the 3.00% Convertible Subordinated Notes exceed 11.8976 per $1,000 principal amount of 3.00% Convertible Subordinated Notes, subject to anti-dilution adjustments, or the equivalent of $84.05 per share of the Company’s common stock or a total of 4,711,283 shares of the Company’s common stock. As of December 31, 2013, the Company expects the holders of the 3.00% Convertible Subordinated Notes to convert their notes into shares of the Company’s common stock prior to the 3.00% Convertible Subordinated Notes maturity date since the Company’s stock price was greater than the base conversion price of the 3.00% Convertible Subordinated Notes. As a result, the Company determined that the principal amount of the 3.00% Convertible Subordinated Notes should be classified as non-current convertible debt on the Company’s consolidated balance sheet as of December 31, 2013 due to the Company’s expectation that the 3.00% Convertible Subordinated Notes will be settled in shares of the Company’s common stock instead of cash. As of December 31, 2013, had the holders of the 3.00% Convertible Subordinated Notes converted their notes, the 3.00% Convertible Subordinated Notes would have been convertible into 3,370,419 shares of the Company’s common stock.
	The conversion rates may be adjusted upon the occurrence of certain events, including for any cash dividend, but they will not be adjusted for accrued and unpaid interest. Holders of the 3.00% Convertible Subordinated Notes will not receive any cash payment representing accrued and unpaid interest upon conversion of a note. Accrued but unpaid interest will be deemed to be paid in full upon conversion rather than cancelled, extinguished or forfeited. The Company may not redeem the 3.00% Convertible Subordinated Notes at its option.
	Holders of the 3.00% Convertible Subordinated Notes have the right to require the Company to purchase with cash all or a portion of the Convertible Subordinated Notes upon the occurrence of a fundamental change such as change of control at a purchase price equal to 100% of the principal amount of the 3.00% Convertible Subordinated Notes plus accrued and unpaid interest, if any, to, but excluding, the date of repurchase. Following certain corporate transactions that constitute a change of control, the Company will increase the conversion rate for a holder who elects to convert the 3.00% Convertible Subordinated Notes in connection with such change of control in certain circumstances.
	The Company has considered the accounting standard for debt with conversion and other options and for derivatives and hedging and has determined that the 3.00% Convertible Subordinated Notes do not contain a beneficial conversion feature as the fair value of the Company’s common stock on the date of issuance was less than the initial conversion price outlined in the agreement.
	4.75% Convertible Subordinated Notes
	In June 2009, the Company issued $373,750,000 aggregate principal amount of 4.75% Convertible Subordinated Notes due June 15, 2016 (the “4.75% Convertible Subordinated Notes”). Interest is payable semi-annually on June 15 and December 15 of each year and commenced on December 15, 2009.
	The 4.75% Convertible Subordinated Notes are governed by an Indenture dated as of June 12, 2009, between the Company, as issuer, and U.S. Bank National Association, as trustee (the “4.75% Convertible Subordinated Notes Indenture”). The 4.75% Convertible Subordinated Notes Indenture does not contain any financial covenants or any restrictions on the payment of dividends, the incurrence of senior debt or other indebtedness, or the issuance or repurchase of securities by the Company. The 4.75% Convertible Subordinated Notes are unsecured and rank junior in right of payment to the Company’s existing or future senior debt and equal in right of payment to the Company’s existing and future subordinated debt.
	Upon conversion, holders will receive, at the Company’s election, cash, shares of the Company’s common stock or a combination of cash and shares of the Company’s common stock. However, the Company may at any time irrevocably elect for the remaining term of the 4.75% Convertible Subordinated Notes to satisfy its obligation in cash up to 100% of the principal amount of the 4.75% Convertible Subordinated Notes, with any remaining amount to be satisfied, at the Company’s election, in shares of its common stock or a combination of cash and shares of its common stock.

	The initial conversion rate is 11.8599 shares of common stock per $1,000 principal amount of 4.75% Convertible Subordinated Notes, subject to adjustment. This represents an initial conversion price of approximately $84.32 per share of common stock. Holders of the 4.75% Convertible Subordinated Notes may convert their notes at any time prior to the close of business on the business day immediately preceding the maturity date under the following circumstances:

		•		during any fiscal quarter (and only during that fiscal quarter) ending after December 31, 2009, if the sale price of the Company’s common stock, for at least 20 trading days during the period of 30 consecutive trading days ending on the last trading day of the previous fiscal quarter, is greater than 130% of the conversion price per share of common stock on such last trading day, which was $109.62 per share (the “Stock Price Condition Conversion Clause”);

	•		subject to certain exceptions, during the five business day period following any 10 consecutive trading day period in which the trading price of the 4.75% Convertible Subordinated Notes for each day of such period was less than 98% of the product of the sale price of the Company’s common stock and the conversion rate (the “4.75% Convertible Subordinated Notes Parity Provision Clause”);

	•		upon the occurrence of specified corporate transactions described in the 4.75% Convertible Subordinated Notes Indenture, such as a consolidation, merger or binding share exchange in which the Company’s common stock would be converted into cash or property other than securities (the “Corporate Action Provision Clause”); or

	•		at any time on or after March 15, 2016.
Upon conversion, if the Company elected to pay a sufficiently large portion of the conversion obligation in cash, additional consideration beyond the $373,750,000 of gross proceeds received would be required.
Holders of the 4.75% Convertible Subordinated Notes were eligible to convert their notes during the year ended December 31, 2013 and are eligible to convert their notes during the three months ending March 31, 2014, since the Stock Price Condition Conversion Clause was met during the applicable periods. As of December 31, 2013, had the holders of the 4.75% Convertible Subordinated Notes converted their notes, the 4.75% Convertible Subordinated Notes would have been convertible into a maximum of 4,432,339 shares of the Company’s common stock.
The conversion rates may be adjusted upon the occurrence of certain events, including for any cash dividend, but they will not be adjusted for accrued and unpaid interest. Holders of the 4.75% Convertible Subordinated Notes will not receive any cash payment representing accrued and unpaid interest upon conversion of a note. Accrued but unpaid interest will be deemed to be paid in full upon conversion rather than cancelled, extinguished or forfeited.
The Company does not have the right to redeem the 4.75% Convertible Subordinated Notes at its option. Holders of the 4.75% Convertible Subordinated Notes have the right to require the Company to purchase with cash all or a portion of the 4.75% Convertible Subordinated Notes upon the occurrence of a fundamental change, such as a change of control at a purchase price equal to 100% of the principal amount of the 4.75% Convertible Subordinated Notes plus accrued and unpaid interest, if any, to, but excluding, the date of repurchase. Following certain corporate transactions that constitute a change of control, the Company will increase the conversion rate for a holder who elects to convert the 4.75% Convertible Subordinated Notes in connection with such change of control in certain circumstances.
Under an accounting standard for convertible debt instruments that may be settled in cash upon conversion (including partial cash settlement), the Company separated the 4.75% Convertible Subordinated Notes into a liability component and an equity component. The carrying amount of the liability component was calculated by measuring the fair value of a similar liability (including any embedded features other than the conversion option) that does not have an associated equity component. The carrying amount of the equity component representing the embedded conversion option was determined by deducting the fair value of the liability component from the initial proceeds ascribed to the 4.75% Convertible Subordinated Notes as a whole. The excess of the principal amount of the liability component over its carrying amount is amortized to interest expense over the expected life of a similar liability that does not have an associated equity component using the effective interest method. The equity component is not remeasured as long as it continues to meet the conditions for equity classification as prescribed in the accounting standard for derivative financial instruments indexed to, and potentially settled in, an entity’s own common stock and the accounting standard for determining whether an instrument (or embedded feature) is indexed to an entity’s own stock.

Issuance and transaction costs incurred at the time of the issuance of the 4.75% Convertible Subordinated Notes with third parties are allocated to the liability and equity components and accounted for as debt issuance costs and equity issuance costs, respectively. The 4.75% Convertible Subordinated Notes consisted of the following as of December 31 (in thousands):


		2013				2012
Equity component (1)		$	104,794			$	104,794

Liability component :
Principal		$	373,724			$	373,730
Less: debt discount, net (2)			(45,508	)			(60,990	)

Net carrying amount		$	328,216			$	312,740


-1	Included in the consolidated balance sheets within additional paid-in capital.
-2	Included in the consolidated balance sheets within convertible debt and is amortized over the remaining life of the 4.75% Convertible Subordinated Notes.
As of December 31, 2013, the remaining life of the 4.75% Convertible Subordinated Notes was 2.46 years.
The following table sets forth total interest expense recognized related to the 4.75% Convertible Subordinated Notes for the years ended December 31 (in thousands):


		2013				2012
Contractual interest expense		$	17,753			$	17,753
Amortization of debt issuance costs			1,022				1,025

		$	34,257			$	32,755

Effective interest rate of the liability component			10.88	%			10.88	%
To minimize the impact of potential dilution upon conversion of the 4.75% Convertible Subordinated Notes, the Company entered into capped call transactions (“the Capped Call”) separate from the issuance of the 4.75% Convertible Subordinated Notes and paid a premium of $49,664,000 for the Capped Call. The Capped Call covers a total of approximately 4,432,638 shares of the Company’s common stock, subject to adjustment. Under the Capped Call, the Company effectively raised the conversion price of the 4.75% Convertible Subordinated Notes from $84.32 to $114.82. Depending upon the Company’s stock price at the time the 4.75% Convertible Subordinated Notes are redeemed, the Capped Call will return up to 1,177,456 shares of the Company’s common stock to the Company; however, the Company will receive no benefit from the Capped Call if the Company’s stock price is $84.32 or lower at the time of conversion and will receive less shares than the 1,177,456 share maximum as described above for share prices in excess of $114.82 at the time of conversion than it would have received at a share price of $114.82 (the Company’s benefit from the Capped Call is capped at $114.82 and the benefit received begins to decrease above this price). In connection with the Capped Call, the Company recorded a $19,000 derivative loss in its consolidated statement of operations for the year ended December 31, 2009, and the remaining $49,645,000 was recorded in additional paid-in capital pursuant to the accounting standard for derivative financial instruments indexed to, and potentially settled in, an entity’s own common stock and the accounting standard for determining whether an instrument (or embedded feature) is indexed to an entity’s own stock.

2.50% Convertible Subordinated Notes
In March 2007, the Company issued $250,000,000 aggregate principal amount of 2.50% Convertible Subordinated Notes due April 15, 2012 (the “2.50% Convertible Subordinated Notes”). Holders of the 2.50% Convertible Subordinated Notes were eligible to convert their notes at any time on or after March 15, 2012 through the close of business on the business day immediately preceding the maturity date. Upon conversion, holders would receive, at the Company’s election, cash, shares of the Company’s common stock or a combination of cash and shares of the Company’s common stock. However, the Company had the right at any time to irrevocably elect for the remaining term of the 2.50% Convertible Subordinated Notes to satisfy its obligation in cash up to 100% of the principal amount of the 2.50% Convertible Subordinated Notes converted, with any remaining amount to be satisfied, at the Company’s election, in shares of its common stock or a combination of cash and shares of its common stock. Upon conversion, due to the conversion formulas associated with the 2.50% Convertible Subordinated Notes, if the Company’s stock was trading at levels exceeding $112.03 per share, and if the Company elected to pay any portion of the consideration in cash, additional consideration beyond the $250,000,000 of gross proceeds received would be required. However, in no event would the total number of shares issuable upon conversion of the 2.50% Convertible Subordinated Notes exceed 11.6036 per $1,000 principal amount of 2.50% Convertible Subordinated Notes, subject to anti-dilution adjustments, or the equivalent of $86.18 per share of common stock or a total of 2,900,900 shares of the Company’s common stock.
In April 2012, virtually all of the holders of the 2.50% Convertible Subordinated Notes converted their notes. The Company settled the $250,000,000 in aggregate principal amount of the 2.50% Convertible Subordinated Notes, plus accrued interest, in $253,132,000 of cash and 622,867 shares of the Company’s common stock that were issued from its treasury stock. The total value of the shares of the Company’s common stock issued by the Company was $95,915,000, which is based on the closing price of the Company’s common stock on April 16, 2012, the date the shares were issued. The number of shares issued to the holders of the 2.50% Convertible Subordinated Notes was based on the volume weighted average price per share of the Company’s common stock for each of the 10 consecutive trading days during the period beginning on the 12^th scheduled trading day immediately preceding the maturity date.
The following table sets forth total interest expense recognized related to the 2.50% Convertible Subordinated Notes during the year ended December 31 (in thousands):

		$	2,250,000			$	1,500,000


4.875% Senior Notes and 5.375% Senior Notes
In March 2013, the Company issued $1,500,000,000 aggregate principal amount of senior notes, which consist of $500,000,000 aggregate principal amount of 4.875% Senior Notes due April 1, 2020 (the “4.875% Senior Notes”) and $1,000,000,000 aggregate principal amount of 5.375% Senior Notes due April 1, 2023 (the “5.375% Senior Notes”). Interest on both the 4.875% Senior Notes and the 5.375% Senior Notes is payable semi-annually on April 1 and October 1 of each year and commenced on October 1, 2013.
The 4.875% Senior Notes and the 5.375% Senior Notes are governed by separate indentures dated March 5, 2013, between the Company, as issuer, and U.S. Bank National Association, as trustee (the “Senior Notes Indentures”). The Senior Notes Indentures contain covenants that limit the Company’s ability and the ability of its subsidiaries to, among other things:

	•		incur additional debt;

	•		pay dividends or make other restricted payments;

	•		purchase, redeem or retire capital stock or subordinated debt;

	•		make asset sales;

	•		enter into transactions with affiliates;

	•		incur liens;

	•		enter into sale-leaseback transactions;

	•		provide subsidiary guarantees;

	•		make investments; and

	•		merge or consolidate with any other person.
Each of these restrictions has a number of important qualifications and exceptions. The 4.875% Senior Notes and the 5.375% Senior Notes are unsecured and rank equal in right of payment with the Company’s existing or future senior debt and senior in right of payment with the Company’s existing and future subordinated debt. The 4.875% Senior Notes and the 5.375% Senior Notes are effectively junior to the Company’s secured indebtedness and indebtedness of its subsidiaries.
At any time prior to April 1, 2016, the Company may on any one or more occasions redeem up to 35% of the aggregate principal amount of the 4.875% Senior Notes outstanding at a redemption price equal to 104.875% of the principal amount of the 4.875% Senior Notes to be redeemed, plus accrued and unpaid interest to, but not including, the redemption date, with the net cash proceeds of one or more equity offerings; provided that (i) at least 65% of the aggregate principal amount of the 4.875% Senior Notes issued under the 4.875% Senior Notes indenture remains outstanding immediately after the occurrence of such redemption (excluding the 4.875% Senior Notes held by the Company and its subsidiaries); and (ii) the redemption must occur within 90 days of the date of the closing of such equity offering.
On or after April 1, 2017, the Company may redeem all or a part of the 4.875% Senior Notes, on any one or more occasions, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest thereon, if any, to, but not including, the applicable redemption date, if redeemed during the twelve-month period beginning on April 1 of the years indicated below:


		Redemption price of the 4.875% Senior Notes
2017			102.438	%
2018			101.219	%
2019 and thereafter			100	%

At any time prior to April 1, 2017, the Company may also redeem all or a part of the 4.875% Senior Notes at a redemption price equal to 100% of the principal amount of the 4.875% Senior Notes redeemed plus an applicable premium (the “4.875% Senior Notes Applicable Premium”), and accrued and unpaid interest, if any, to, but not including, the date of redemption (the “4.875% Senior Notes Redemption Date”). The 4.875% Senior Notes Applicable Premium means the greater of:

	•		1.0% of the principal amount of the 4.875% Senior Notes; and

	•		the excess of: (a) the present value at such redemption date of (i) the redemption price of the 4.875% Senior Notes at April 1, 2017 as shown in the above table, plus (ii) all required interest payments due on the 4.875% Senior Notes through April 1, 2017 (excluding accrued but unpaid interest, if any, to, but not including the 4.875% Senior Notes Redemption Date), computed using a discount rate equal to the yield to maturity of the U.S. Treasury securities with a constant maturity most nearly equal to the period from the 4.875% Senior Notes Redemption Date to April 1, 2017, plus 0.50%; over (b) the principal amount of the 4.875% Senior Notes.
At any time prior to April 1, 2016, the Company may on any one or more occasions redeem up to 35% of the aggregate principal amount of the 5.375% Senior Notes outstanding at a redemption price equal to 105.375% of the principal amount of the 5.375% Senior Notes to be redeemed, plus accrued and unpaid interest to, but not including, the redemption date, with the net cash proceeds of one or more equity offerings; provided that (i) at least 65% of the aggregate principal amount of the 5.375% Senior Notes issued under the 5.375% Senior Notes indenture remains outstanding immediately after the occurrence of such redemption (excluding the 5.375% Senior Notes held by the Company and its subsidiaries); and (ii) the redemption must occur within 90 days of the date of the closing of such equity offering.
On or after April 1, 2018, the Company may redeem all or a part of the 5.375% Senior Notes, on any one or more occasions, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest thereon, if any, to, but not including, the applicable redemption date, if redeemed during the twelve-month period beginning on April 1 of the years indicated below:


		Redemption price of the 5.375% Senior Notes
2018			102.688	%
2019			101.792	%
2020			100.896	%
2021 and thereafter			100	%
At any time prior to April 1, 2018, the Company may also redeem all or a part of the 5.375% Senior Notes at a redemption price equal to 100% of the principal amount of the 5.375% Senior Notes redeemed plus an applicable premium (the “5.375% Senior Notes Applicable Premium”), and accrued and unpaid interest, if any, to, but not including, the date of redemption (the “5.375% Senior Notes Redemption Date”). The 5.375% Senior Notes Applicable Premium means the greater of:

	•		1.0% of the principal amount of the 5.375% Senior Notes; and

	•		the excess of: (a) the present value at such redemption date of (i) the redemption price of the 5.375% Senior Notes at April 1, 2018 as shown in the above table, plus (ii) all required interest payments due on the 5.375% Senior Notes through April 1, 2018 (excluding accrued but unpaid interest, if any, to, but not including the 5.375% Senior Notes Redemption Date), computed using a discount rate equal to the yield to maturity of the U.S. Treasury securities with a constant maturity most nearly equal to the period from the 5.375% Senior Notes Redemption Date to April 1, 2018, plus 0.50%; over (b) the principal amount of the 5.375% Senior Notes.
Debt issuance costs related to the 4.875% Senior Notes and 5.375% Senior Notes, net of amortization, were $18,503,000 as of December 31, 2013. In March 2013, the Company placed $836,400,000 of the proceeds from the issuance of the 4.875% and 5.375% Senior Notes into a restricted cash account for the redemption of the 8.125% Senior Notes (see below).

7.00% Senior Notes
In July 2011, the Company issued $750,000,000 aggregate principal amount of 7.00% Senior Notes due July 15, 2021 (the “7.00% Senior Notes”). Interest is payable semi-annually in arrears on January 15 and July 15 of each year and commenced on January 15, 2012.
The 7.00% Senior Notes are governed by an indenture dated July 6, 2011 between the Company, as issuer, and U.S. Bank National Association, as trustee (the “7.00% Senior Notes Indenture”). The 7.00% Senior Notes Indenture contains covenants that limit the Company’s ability and the ability of its subsidiaries to, among other things:

	•		incur additional debt;

	•		pay dividends or make other restricted payments;

	•		purchase, redeem or retire capital stock or subordinated debt;

	•		make asset sales;

	•		enter into transactions with affiliates;

	•		incur liens;

	•		enter into sale-leaseback transactions;

	•		provide subsidiary guarantees;

	•		make investments; and

	•		merge or consolidate with any other person.
Each of these restrictions has a number of important qualifications and exceptions. The 7.00% Senior Notes are unsecured and rank equal in right of payment to the Company’s existing or future senior debt and senior in right of payment to the Company’s existing and future subordinated debt including the Company’s convertible debt. The 7.00% Senior Notes are effectively junior to any of the Company’s existing and future secured indebtedness and any secured indebtedness of its subsidiaries. The 7.00% Senior Notes are also structurally subordinated to all debt and other liabilities (including trade payables) of the Company’s subsidiaries and will continue to be subordinated to the extent that these subsidiaries do not guarantee the 7.00% Senior Notes in the future.
At any time prior to July 15, 2014, the Company may on any one or more occasions redeem up to 35% of the aggregate principal amount of the 7.00% Senior Notes outstanding under the 7.00% Senior Notes Indenture, at a redemption price equal to 107.000% of the principal amount of the 7.00% Senior Notes to be redeemed, plus accrued and unpaid interest to, but not including, the redemption date, with the net cash proceeds of one or more equity offerings, provided that (i) at least 65% of the aggregate principal amount of the 7.00% Senior Notes issued under the 7.00% Senior Notes Indenture remains outstanding immediately after the occurrence of such redemption and (ii) the redemption must occur within 90 days of the date of the closing of such equity offerings. On or after July 15, 2016, the Company may redeem all or a part of the 7.00% Senior Notes, on any one or more occasions, at the redemption prices set forth below plus accrued and unpaid interest thereon, if any, up to, but not including, the applicable redemption date, if redeemed during the twelve-month period beginning on July 15 of the years indicated below:


		Redemption price of the Senior Notes
2016			103.5	%
2017			102.333	%
2018			101.167	%
2019 and thereafter			100	%

In addition, at any time prior to July 15, 2016, the Company may also redeem all or a part of the 7.00% Senior Notes at a redemption price equal to 100% of the principal amount of the 7.00% Senior Notes redeemed plus an applicable premium (the “Applicable Premium”) and accrued and unpaid interest, if any, to, but not including, the date of redemption (the “Redemption Date”). The Applicable Premium means the greater of:

	•		1.0% of the principal amount of the 7.00% Senior Notes to be redeemed; and

	•		the excess of: (a) the present value at such redemption date of (i) the redemption price of the 7.00% Senior Notes to be redeemed at July 15, 2016 as shown in the above table, plus (ii) all required interest payments due on these 7.00% Senior Notes through July 15, 2016 (excluding accrued but unpaid interest, if any, to, but not including the redemption date), computed using a discount rate equal to the yield to maturity as of the redemption date of the U.S. Treasury securities with a constant maturity most nearly equal to the period from the redemption date to July 15, 2016, plus 0.50%; over (b) the principal amount of the 7.00% Senior Notes to be redeemed.
Upon a change in control, the Company will be required to make an offer to purchase each holder’s 7.00% Senior Notes at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest to the date of purchase.
Debt issuance costs related to the 7.00% Senior Notes, net of amortization, were $10,704,000 as of December 31, 2013.
8.125% Senior Notes
In February 2010, the Company issued $750,000,000 aggregate principal amount of 8.125% Senior Notes due March 1, 2018 (the “8.125% Senior Notes”). Interest was payable semi-annually on March 1 and September 1 of each year and commenced on September 1, 2010. The indenture governing the 8.125% Senior Notes permitted the Company to redeem the 8.125% Senior Notes at the redemption prices set forth in the 8.125% Senior Notes indenture plus accrued and unpaid interest to, but not including the redemption date.
In April 2013, the Company redeemed the entire principal amount of the 8.125% Senior Notes pursuant to the optional redemption provisions in the indenture governing the 8.125% Senior Notes, plus accrued interest, in cash of $836,511,000, which included the applicable premium paid of $80,925,000. As a result, the Company recognized a loss on debt extinguishment during the three months ended June 30, 2013.
Loss on Debt Extinguishment
During the year ended December 31, 2013, the Company recorded $108,501,000 of loss on debt extinguishment primarily comprised of (i) $93,602,000 loss on debt extinguishment from the redemption of the 8.125% Senior Notes, which included $8,927,000 related to the write-off of unamortized debt issuance costs and $3,750,000 of other transaction-related fees, (ii) $13,189,000 from the London IBX Financing (see Note 9) and (iii) $1,710,000 from an amendment of the New York 5 and 6 IBX lease.
During the year ended December 31, 2012, the Company recorded $5,204,000 of loss on debt extinguishment due to the write-off of unamortized debt issuance costs associated with the prepayment and termination of a multi-currency credit facility in the Company’s Asia-Pacific region.

	11	Redeemable Non-Controlling Interests
	As a result of the ALOG Acquisition (Note 3), the Company recorded redeemable non-controlling interests. Given the provisions in the ALOG Acquisition related to the put and call options, the Company adjusts its redeemable non-controlling interests to redemption value on each balance sheet date with corresponding increases/decreases recognized as adjustments to retained earnings or, in the absence of retained earnings, additional paid-in capital. The redemption value of the non-controlling interests is estimated by applying an income approach. Under the income approach, the Company develops a cash flow forecast and uses its estimated weighted-average cost of capital applicable to ALOG as the discount rate. The significant assumptions used to estimate the redemption value of the non-controlling interests include projected revenue growth, sales and marketing expenses, operating margins, capital expenditures and the discount rate. The measurement of the redemption value of the non-controlling interests was based on significant inputs that are not observable in the market and thus represents a Level 3 measurement.

	The following table provides a summary of the activities of the Company’s redeemable non-controlling interests (in thousands):


	Balance at December 31, 2011		$	67,601
	Net income attributable to redeemable non-controlling interests			3,116

	Changes in foreign currencies can have a significant impact to the Company’s consolidated balance sheets (as evidenced above in the Company’s foreign currency translation gain or loss), as well as its consolidated results of operations, as amounts in foreign currencies are generally translating into more U.S. dollars when the U.S. dollar weakens or less U.S. dollars when the U.S. dollar strengthens. At December 31, 2013, the U.S. dollar was generally stronger relative to certain of the currencies of the foreign countries in which the Company operates. This overall strength of the U.S. dollar had an overall negative impact on the Company’s consolidated financial position because the foreign denominations translated into less U.S. dollars as evidenced by an increase in foreign currency translation loss for the year ended December 31, 2013 compared to the year ended December 31, 2012 as reflected in the above table. In future periods, the volatility of the U.S. dollar as compared to the other currencies in which the Company does business could have a significant impact on its consolidated financial position and results of operations including the amount of revenue that the Company reports in future periods.

	ALOG Equity Awards
	In July 2011, ALOG, in which the Company has an indirect controlling interest (see Note 3), granted 885,840 stock options to purchase common shares of ALOG to certain of ALOG’s employees with a weighted-average exercise price of approximately $6.35 and a weighted-average fair value of approximately $1.53 (the “2011 ALOG Stock Options”). The 2011 ALOG Stock Options were cancelled in December 2012 and replaced with a new grant of stock options for 18,421,648 shares of which stock options for 4,711,808 shares were immediately vested (the “2012 ALOG Stock Options”). The 2012 ALOG Stock Options are accounted for as liability-classified awards under the accounting standard for share-based payments and will be re-measured each reporting period prospectively until the underlying shares are settled. Under certain circumstances, the 2012 ALOG Stock Options are eligible for net cash settlement by the stock option holders. The weighted-average fair value per share of the 2012 ALOG Stock Options on the date of the grant was approximately $0.11, which was computed using the Black-Scholes model with assumptions as follows:


	Average exercise price		$	0.28
	Expected life (years)			1.35
	Dividend yield			0	%
	Volatility			44	%
	Risk-free interest rate			7.3	%
	During the year ended December 31, 2013, stock options for 1,986,912 shares were exercised. As of December 31, 2013, the Company had a total stock-based compensation liability of $3,778,000 from the 2012 ALOG Stock Options.
	Equinix Equity Awards
	Equity Compensation Plans
	In May 2000, the Company’s stockholders approved the adoption of the 2000 Equity Incentive Plan as the successor plan to the 1998 Stock Plan. Beginning in August 2000, the Company no longer issued additional grants under the 1998 Stock Plan, and unexercised options under the 1998 Stock Plan that are canceled due to an optionee’s termination may be reissued under the successor 2000 Equity Incentive Plan. Under the 2000 Equity Incentive Plan, nonstatutory stock options, restricted shares, restricted stock units, and stock appreciation rights may be granted to employees, outside directors and consultants at not less than 85% of the fair value on the date of grant, and incentive stock options may be granted to employees at not less than 100% of the fair value on the date of grant. Options granted prior to October 1, 2005 generally expire 10 years from the grant date, and equity awards granted to employees and consultants on or after October 1, 2005 will generally expire seven years from the grant date, subject to continuous service of the optionee. Equity awards granted under the 2000 Equity Incentive Plan generally vest over four years. As of December 31, 2013, the Company had reserved a total of 16,807,926, shares for issuance under the 2000 Equity Incentive Plan of which 4,718,738 were still available for grant. The 2000 Equity Incentive Plan is administered by the Compensation Committee of the Board of Directors (the “Compensation Committee”), and the Compensation Committee may terminate or amend the plan, with approval of the stockholders as may be required by applicable law, at any time.
	In May 2000, the Company’s stockholders approved the adoption of the 2000 Director Option Plan, which was amended and restated effective January 1, 2003. Under the 2000 Director Option Plan, each non-employee board member who was not previously an employee of the Company will receive an automatic initial nonstatutory stock option grant, which vests in four annual installments. In addition, each non-employee board member will receive an annual non-statutory stock option grant on the date of the Company’s regular Annual Meeting of Stockholders, provided the board member will continue to serve as a director thereafter. Such annual option grants shall vest in full on the earlier of a) the first anniversary of the grant, or b) the date of the regular Annual Meeting of Stockholders held in the year following the grant date. A new director who receives an initial option will not receive an annual option in the same calendar year. Options granted under the 2000 Director Option Plan will have an option price not less than 100% of the fair value on the date of grant and will have a 10-year contractual term, subject to continuous service of the board member. On December 18, 2008, the Company’s Board of Directors passed resolutions eliminating all automatic stock option grant mechanisms under the 2000 Director Option Plan, and replaced them with an automatic restricted stock unit grant mechanism under the 2000 Equity Incentive Plan. As of December 31, 2013, the Company had reserved 593,440 shares for issuance under the 2000 Director Option Plan of which 505,938 were still available for grant. The 2000 Director Option Plan is administered by the Compensation Committee and the Compensation Committee may terminate or amend the plan, with approval of the stockholders as may be required by applicable law, at any time.

	In September 2001, the Company adopted the 2001 Supplemental Stock Plan, under which non-statutory stock options and restricted shares/restricted stock units may be granted to consultants and employees who are not executive officers or board members, at not less than 85% of the fair value on the date of grant. Options granted prior to October 1, 2005 generally expire 10 years from the grant date, and options granted on or after October 1, 2005 will generally expire seven years from the grant date, subject to continuous service of the optionee. Current stock options granted under the 2001 Supplemental Stock Plan generally vest over four years. As of December 31, 2013, the Company had reserved a total of 1,493,961 shares for issuance under the 2001 Supplemental Stock Plan, of which 260,326 were still available for grant. The 2001 Supplemental Stock Plan is administered by the Compensation Committee, and the plan will continue in effect indefinitely unless the Compensation Committee decides to terminate it earlier.
	The 1998 Stock Plan, 2000 Equity Incentive Plan, 2000 Director Option Plan, 2001 Supplemental Stock Plan and Switch and Data 2007 Stock Incentive Plan are collectively referred to as the “Equity Compensation Plans.”

Restricted Shares and Restricted Stock Units
Restricted Shares
During 2006 and 2007, the Company granted issued and outstanding restricted shares to its executive officers. At the date of the grant, the Company issued these shares into restricted book-entry escrow accounts under the names of each of the executive officers. These shares had voting rights and were considered issued and outstanding. They were released from the escrow account as they vested. However, they were subject to forfeiture (and, therefore, canceled) if the individual officers did not meet the vesting requirements. The activity of these restricted shares is as follows:


		Number of				Weighted-average
		shares				grant date fair
		outstanding				value per share
Restricted shares outstanding, December 31, 2010			31,334			$	72.3
Restricted shares released, vested			(23,834	)			68.67

Restricted shares released, vested			(7,500	)			83.84

Restricted shares outstanding, December 31, 2012			—				—


Restricted Stock Units
Since 2008, the Company primarily grants restricted stock units to its employees, including executives and non-employee directors, in lieu of stock options. The Company generally grants restricted stock units that have a service condition only or have both a service and performance condition. Each restricted stock unit is not considered issued and outstanding and does not have voting rights until it is converted into one share of the Company’s common stock upon vesting. Restricted stock unit activity is summarized as follows:


		Number of				Weighted-			Weighted-			Aggregate
		shares				average			average			intrinsic
		outstanding				grant date			remaining			value (1)

Total fair value of restricted stock units vested and released during the years ended December 31, 2013, 2012 and 2011 was $147,119,000, $68,738,000 and $54,659,000.
Employee Stock Purchase Plan
In June 2004, the Company’s stockholders approved the adoption of the 2004 Employee Stock Purchase Plan (the “2004 Purchase Plan”) as a successor plan to a previous plan that ceased activity in 2005. A total of 500,000 shares have been reserved for issuance under the 2004 Purchase Plan, and the number of shares available for issuance under the 2004 Purchase Plan automatically increases on January 1 each year, beginning in 2005, by the lesser of 2% of the shares of common stock then outstanding or 500,000 shares. As of December 31, 2013, a total of 3,414,253 shares remained available for purchase under the 2004 Purchase Plan. The 2004 Purchase Plan permits eligible employees to purchase common stock on favorable terms via payroll deductions of up to 15% of the employee’s cash compensation, subject to certain share and statutory dollar limits. Two overlapping offering periods commence during each calendar year, on each February 15 and August 15 or such other periods or dates as determined by the Compensation Committee from time to time, and the offering periods last up to 24 months with a purchase date every six months. The price of each share purchased is 85% of the lower of a) the fair value per share of common stock on the last trading day before the commencement of the applicable offering period or b) the fair value per share of common stock on the purchase date. The 2004 Purchase Plan is administered by the Compensation Committee of the Board of Directors, and such plan will terminate automatically in June 2014 unless a) the 2004 Purchase Plan is extended by the Board of Directors and b) the extension is approved within 12 months by the Company’s stockholders.

The Company provides the following disclosures for the 2004 Purchase Plan as of December 31 (dollars, except shares):


		2013				2012			2011

Number of shares purchased			214,985				220,290			211,840
The Company uses the Black-Scholes option-pricing model to determine the fair value of shares purchased under the 2004 Purchase Plan with the following weighted average assumptions for the years ended December 31:


		2013				2012			2011
Dividend yield			0	%			0	%		0	%

Expected life (in years)			1.25				1.25			1.25
Stock-Based Compensation Recognized in the Consolidated Statement of Operations
The Company generally recognizes stock-based compensation expense on a straight-line basis over the requisite service period of the awards. However, for awards with market conditions or performance conditions, stock-based compensation expense is recognized on a straight-line basis over the requisite service period for each vesting tranche of the award.
As of December 31, 2013, the total stock-based compensation cost related to unvested equity awards not yet recognized, net of estimated forfeitures, totaled $172,702,000 which is expected to be recognized over a weighted-average period of 2.01 years.
The following table presents, by operating expense, the Company’s stock-based compensation expense recognized in the Company’s consolidated statement of operations for the years ended December 31 (in thousands):

State and foreign taxes not based on income are included in general and administrative expenses and the aggregated amount is insignificant for the years ended December 31, 2013, 2012 and 2011.
	The Company is entitled to a deduction for federal and state tax purposes with respect to employee equity award activity. The reduction in income tax payable related to windfall tax benefits for stock based compensation awards has been reflected as an adjustment to additional paid-in capital. For the years ended December 31, 2013, 2012 and 2011, the benefits arising from employee equity award activity that resulted in an adjustment to additional paid in capital were approximately $25,638,000, $84,740,000 and $81,000, respectively.

	The Company has not provided for deferred taxes on the excess of the financial reporting over the tax basis in its investments in foreign subsidiaries that are essentially permanent in duration because the Company intends to reinvest the earnings outside the U.S. for an indefinite period of time. The determination of the additional taxes that have not been provided is not practicable to compute based upon the complexities in tax law across the juridictions in which the Company operates. As of December 31, 2013, certain of the Company’s foreign subsidiaries had positive cumulative undistributed earnings totaling approximately $426,353,000.
	The types of temporary differences that give rise to significant portions of the Company’s deferred tax assets and liabilities are set out below as of December 31 (in thousands):


			2013				2012

Net deferred tax liabilities		$	95,601			$	(30,072	)

The net deferred tax assets and liabilities as of December 31, 2013 and 2012, respectively, are attributable to the Company’s operations in the United States, Canada and certain entities in Europe, Asia-Pacific and Brazil.
During the year ended December 31, 2012, as a result of the Asia Tone Acquisition, the Company recognized deferred tax liabilities of approximately $12,200,000, $2,100,000 and $860,000 in Hong Kong, China and Singapore, respectively, attributable to identifiable intangibles and fixed assets fair value step-ups related to the acquisition. In addition, as a result of the ancotel Acquisition, the Company recognized a deferred tax liability of approximately $13,600,000 in Germany attributable to identifiable intangibles and fixed assets fair value step-ups related to the acquisition.

The Company’s accounting for deferred taxes involves weighing positive and negative evidence concerning the realizability of the Company’s deferred tax assets in each tax jurisdiction. After considering such evidence as the nature, frequency and severity of current and cumulative financial reporting losses, and the sources of future taxable income and tax planning strategies, management concluded that a 100% valuation allowance was required in certain foreign jurisdictions. A valuation allowance is provided for the deferred tax assets, net of deferred tax liabilities, associated with the Company’s operations in certain jurisdictions located in the Company’s EMEA and Asia-Pacific regions, as well as an entity in Brazil. The operations in these jurisdictions still have significant losses as of the end of 2013. As such, management does not believe these operations have established a sustained history of profitability and that a valuation allowance is, therefore, necessary.
During the year ended December 31, 2013, the Company released the valuation allowance of $3,211,000 against the net deferred tax assets of certain operating entities in both the America and EMEA regions as a result of reorganizations completed in the regions during the year. In addition, the Company established full valuation allowances of $339,000 against the net deferred tax assets of certain foreign operating entities. These foreign operating entities have incurred losses and it is expected that the businesses will not be profitable in the foreseeable future. Management cannot conclude it is more likely than not that the deferred tax assets of the foreign operating entities will be realizable in the foreseeable future as the entities have not established a sustainable profitability history.
During the year ended December 31, 2012, the Company established full valuation allowances of $5,500,000 against the net deferred tax assets of certain foreign operating entities.
During the year ended December 31, 2011, the Company released the valuation allowance of $2,493,000 against the deferred tax assets of certain foreign operating entities.
Changes in valuation allowance for deferred tax assets for the years ended December 31, 2013, 2012, and 2011 are as follows:


		2013				2012				2011
Beginning balance		$	44,868			$	40,863			$	42,040

Federal and state tax laws, including California tax laws, impose substantial restrictions on the utilization of net operating loss and credit carryforwards in the event of an “ownership change” for tax purposes, as defined in Section 382 of the Internal Revenue Code. In 2003, the Company conducted an analysis to determine whether an ownership change had occurred due to significant stock transactions in each of the reporting years disclosed at that time. The analysis indicated that an ownership change occurred during fiscal year 2002, which resulted in an annual limitation of approximately $819,000 for net operating loss carryforwards generated prior to 2003. Therefore, the Company substantially reduced its federal and state net operating loss carryforwards for the periods prior to 2003 to approximately $16,400,000. In addition, an ownership change under Section 382 of the Internal Revenue Code was triggered in September 2007 by the issuance of 4,211,939 shares of the Company’s common stock. However, the annual limitation associated with this ownership change is not meaningful due to the substantial market capitalization of the Company at the time of the ownership change. The Company determined that no Section 382 ownership change occurred in 2013. In addition, the net operating loss acquired in the Switch and Data Acquisition is subject to the Section 382 limitation; however, the Company has determined that none of the acquired net operating losses will expire unused as a result of the limitation.

The Company utilized all of its net operating loss carryforwards that were not subject to the limitation under Section 382 as discussed above for federal income tax purposes in 2013. The Company’s U.S. operations generated significant taxable income for the year ended December 31, 2013 and 2012 primarily due to the large amount of taxable gain recognized during 2012 in connection with the Divestiture and the change in the tax method for depreciation of the Company’s property, plant and equipment. As the result of announcing its plan to pursue a REIT conversion, the Company changed its methods of depreciating and amortizing various data center assets to methods that are more consistent with the characterization of such assets as real property for REIT purposes. The change in the depreciation method resulted in the recapture of depreciation expense deducted in prior years and a much smaller amount of depreciation expense for the years ended December 31, 2013 and 2012.
The Company’s net operating loss carryforwards for foreign tax purposes which expire, if not utilized, at various intervals from 2013, are outlined below (in thousands):


Expiration Date		Federal (1)				State (1)				Foreign				Total
2013 to 2015		$	—			$	—			$	67			$	67

-1	The total amount of net operating loss carryforwards that will not be available to offset the Company’s future taxable income due to Section 382 limitations was $286,054, comprising $241,766 of federal and $44,288 of state.
Approximately $1,684,000 of the total net operating loss carryforwards is attributable to excess tax deductions related to employee stock awards, the benefit from which will be credited to additional paid-in capital when subsequently utilized in future years.
The beginning and ending balances of the Company’s unrecognized tax benefits are reconciled below for the years ended December 31 (in thousands):


		2013				2012				2011
Beginning balance		$	25,050			$	34,105			$	16,583

Decreases resulting from settlements			—				(1,014	)			(57	)

Ending balance		$	36,552			$	25,050			$	34,105

As a result of the ancotel Acquisition, the Company’s unrecognized tax benefits for the year ended December 31, 2012 increased by $82,000 for various uncertain tax positions related to prior years. In addition, as a result of the ALOG Acquisition, the Company increased the unrecognized tax benefits, including the accrued interest and penalties as of the acquisition date by $22,918,000 during the year ended December 31, 2011 related to the uncertain tax positions taken prior to both acquisitions.
The Company recognizes accrued interest expense related to unrecognized tax benefits in interest expense and penalties in operating expenses. During the years ended December 31, 2011 and 2012, the Company recognized approximately $9,424,000, $719,000 in interest and penalties, respectively. During the year ended December 31, 2013, the accrued interest and penalties related to the unrecognized tax benefits were decreased by $1,612,000 primarily resulting from the settlement of a tax audit and the lapse of statutes of limitations in our foreign operations. The Company had approximately $10,175,000 and $8,563,000 for the payment of interest and penalties accrued at December 31, 2012 and 2013, respectively.

The unrecognized tax benefits of $36,552,000 as of December 31, 2013, if subsequently recognized, will affect the Company’s effective tax rate favorably at the time when such a benefit is recognized.
Due to various tax years open for examination, it is reasonably possible that the balance of unrecognized tax benefits could significantly increase or decrease over the next 12 months as the Company may be subject to either examination by tax authorities or a lapse in statute of limitations. The Company is currently unable to estimate the range of possible adjustments to the balance of unrecognized tax benefits.
The Company’s income tax returns for all tax years remain open to examination by federal and state taxing authorities due to the Company’s net operating loss carryforwards. In addition, the Company’s tax years of 2003 through 2012 remain open and subject to examination by local tax authorities in certain foreign jurisdictions in which the Company has major operations. There was one pending income tax audit in a non-U.S. jurisdiction during the year ended December 31, 2013, which has been open since 2010; the Company received a preliminary assessment for the audits and has filed the request to appeal the assessment. The Company believes that it has a sufficient reserve for the assessment and the final outcome of the appeal will not significantly impact the Company’s financial position.

	Legal Matters
	Alleged Class Action and Shareholder Derivative Actions
	On March 4, 2011, an alleged class action entitled Cement Masons & Plasterers Joint Pension Trust v. Equinix, Inc., et al., No. CV-11-1016-SC, was filed in the United States District Court for the Northern District of California, against Equinix and two of its officers. The suit asserts purported claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 for allegedly misleading statements regarding the Company’s business and financial results. The suit is purportedly brought on behalf of purchasers of the Company’s common stock between July 29, 2010 and October 5, 2010, and seeks compensatory damages, fees and costs. Defendants filed a motion to dismiss on November 7, 2011. On March 2, 2012, the Court granted defendants’ motion to dismiss without prejudice and gave plaintiffs thirty days in which to amend their complaint. Pursuant to stipulation and order of the court entered on March 16, 2012, the parties agreed that plaintiffs would have up to and through May 2, 2012 to file a Second Amended Complaint. On May 2, 2012 plaintiffs filed a Second Amended Complaint asserting the same basic allegations as in the prior complaint. On June 15, 2012, defendants moved to dismiss the Second Amended Complaint. On September 19, 2012, the Court took the hearing on defendants’ motion to dismiss the Second Amended Complaint off calendar and notified the parties that it would make its decision on the pleadings. Subsequently, on September 24, 2012 the Court requested the parties submit supplemental briefing on or before October 9, 2012. The supplemental briefing was submitted on October 9, 2012. On December 5, 2012, the Court granted defendants’ motion to dismiss the Second Amended Complaint without prejudice and on January 15, 2013, Plaintiffs filed their Third Amended Complaint. On February 26, 2013, defendants moved to dismiss the Third Amended Complaint. On June 12, 2013, the Court granted defendants’ motion to dismiss the Third Amended Complaint and dismissed the case with prejudice. On July 3, 2013, plaintiffs stipulated that they will not appeal any prior orders issued by the Court in this action, including the Court’s June 12, 2013 order dismissing the Third Amended Complaint with prejudice.

	On March 8, 2011, an alleged shareholder derivative action entitled Rikos v. Equinix, Inc., et al., No. CGC-11-508940, was filed in California Superior Court, County of San Francisco, purportedly on behalf of Equinix, and naming Equinix (as a nominal defendant), the members of its board of directors, and two of its officers as defendants. The suit is based on allegations similar to those in the federal securities class action and asserts causes of action against the individual defendants for breach of fiduciary duty, abuse of control, gross mismanagement, waste of corporate assets and unjust enrichment. By agreement and order of the court, this case has been temporarily stayed pending proceedings in the class action. On June 25, 2013, the parties entered into a stipulation dismissing the case with prejudice, and on July 11, 2013, the Court entered an order of dismissal with prejudice.
	On May 20, 2011, an alleged shareholder derivative action entitled Stopa v. Clontz, et al., No. CV-11-2467-SC, was filed in the U.S. District Court for the Northern District of California, purportedly on behalf of Equinix, naming Equinix (as a nominal defendant) and the members of its board of directors as defendants. The suit is based on allegations similar to those in the federal securities class action and the state court derivative action and asserts causes of action against the individual defendants for breach of fiduciary duty, unjust enrichment, abuse of control, gross mismanagement and waste of corporate assets. On June 10, 2011, the Court signed an order relating this case to the federal securities class action. Plaintiffs filed an amended complaint on December 14, 2011. By agreement and order of the court, this case has been temporarily stayed pending proceedings in the class action. On July 9, 2013, the parties entered into a stipulation dismissing the case with prejudice, and on July 10, 2013, the Court entered an order of dismissal with prejudice.
	Contingent Liabilities
	The Company estimates exposure on certain liabilities, such as income and property taxes, based on the best information available at the time of determination. With respect to real and personal property taxes, the Company records what it can reasonably estimate based on prior payment history, current landlord estimates or estimates based on current or changing fixed asset values in each specific municipality, as applicable. However, there are circumstances beyond the Company’s control whereby the underlying value of the property or basis for which the tax is calculated on the property may change, such as a landlord selling the underlying property of one of the Company’s IBX data center leases or a municipality changing the assessment value in a jurisdiction and, as a result, the Company’s property tax obligations may vary from period to period. Based upon the most current facts and circumstances, the Company makes the necessary property tax accruals for each of its reporting periods. However, revisions in the Company’s estimates of the potential or actual liability could materially impact the financial position, results of operations or cash flows of the Company.
	From time to time, the Company may have certain contingent liabilities that arise in the ordinary course of its business activities. The Company accrues contingent liabilities when it is probable that future expenditures will be made and such expenditures can be reasonably estimated. In the opinion of management, there are no pending claims for which the outcome is expected to result in a material adverse effect in the financial position, results of operations or cash flows of the Company.
	Employment Agreements
	The Company has entered into a severance agreement with each of its executive officers that provides for a severance payment equal to the executive officer’s annual base salary and maximum bonus in the event his or her employment is terminated for any reason other than cause or he or she voluntarily resigns under certain circumstances as described in the agreement. In addition, under the agreement, the executive officer is entitled to the payment of his or her monthly health care premiums under the Consolidated Omnibus Budget Reconciliation Act for up to 12 months. For certain executive officers, these benefits are only triggered after a change-in-control of the Company.

	Guarantor Arrangements
	As permitted under Delaware law, the Company has agreements whereby the Company indemnifies its officers and directors for certain events or occurrences while the officer or director is, or was serving, at the Company’s request in such capacity. The term of the indemnification period is for the officer’s or director’s lifetime. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited; however, the Company has a director and officer insurance policy that limits the Company’s exposure and enables the Company to recover a portion of any future amounts paid. As a result of the Company’s insurance policy coverage, the Company believes the estimated fair value of these indemnification agreements is minimal. The Company has no liabilities recorded for these agreements as of December 31, 2013.
	The Company enters into standard indemnification agreements in the ordinary course of business. Pursuant to these agreements, the Company indemnifies, holds harmless, and agrees to reimburse the indemnified party for losses suffered or incurred by the indemnified party, generally the Company’s business partners or customers, in connection with any U.S. patent, or any copyright or other intellectual property infringement claim by any third party with respect to the Company’s offerings. The term of these indemnification agreements is generally perpetual any time after execution of the agreement. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited; however, the Company has never incurred costs to defend lawsuits or settle claims related to these indemnification agreements. As a result, the Company believes the estimated fair value of these agreements is minimal. The Company has no liabilities recorded for these agreements as of December 31, 2013.
	The Company enters into arrangements with its business partners, whereby the business partner agrees to provide services as a subcontractor for the Company’s implementations. Accordingly, the Company enters into standard indemnification agreements with its customers, whereby the Company indemnifies them for other acts, such as personal property damage, of its subcontractors. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited; however, the Company has general and umbrella insurance policies that enable the Company to recover a portion of any amounts paid. The Company has never incurred costs to defend lawsuits or settle claims related to these indemnification agreements. As a result, the Company believes the estimated fair value of these agreements is minimal. The Company has no liabilities recorded for these agreements as of December 31, 2013.
	The Company has service level commitment obligations to certain of its customers. As a result, service interruptions or significant equipment damage in the Company’s IBX data centers, whether or not within the Company’s control, could result in service level commitments to these customers. The Company’s liability insurance may not be adequate to cover those expenses. In addition, any loss of services, equipment damage or inability to meet the Company’s service level commitment obligations could reduce the confidence of the Company’s customers and could consequently impair the Company’s ability to obtain and retain customers, which would adversely affect both the Company’s ability to generate revenues and the Company’s operating results. The Company generally has the ability to determine such service level credits prior to the associated revenue being recognized. The Company has no significant liabilities in connection with service level credits as of December 31, 2013.

	18	Restructuring Charges
	2004 Restructuring Charge
	In December 2004, in light of the availability of fully built-out data centers in select markets at costs significantly below those costs the Company would incur in building out new space, the Company made the decision to exit leases for excess space adjacent to one of the Company’s New York metro area IBXs, as well as space on the floor above its original Los Angeles IBX. As a result of the Company’s decision to exit these spaces, the Company recorded restructuring charges totaling $17,685,000, which represents the present value of the Company’s estimated future cash payments, net of estimated sublease income and expense, through the remainder of these lease terms, as well as the write-off of all remaining property, plant and equipment attributed to the partial build out of the excess space on the floor above its Los Angeles IBX.
	In May 2013, the Company entered into a binding commitment to purchase the New York 2 IBX data center for leased space in respect of which the Company had previously recorded a restructuring reserve (see Note 6). As a result, the Company recorded a reversal to its outstanding accrued restructuring charge during the year ended December 31, 2013.
	A summary of the movement in the 2004 accrued restructuring charges during the years ended December 31 is outlined as follows (in thousands):


	Accrued restructuring charge as of December 31, 2010		$	6,006
	Accretion expense			377

	20	Quarterly Financial Information (Unaudited)
	The Company believes that period-to-period comparisons of its financial results should not be relied upon as an indication of future performance. The Company’s revenues and results of operations have been subject to significant fluctuations, particularly on a quarterly basis, and the Company’s revenues and results of operations could fluctuate significantly quarter-to-quarter and year-to-year. Significant quarterly fluctuations in revenues will cause fluctuations in the Company’s cash flows and the cash and cash equivalents and accounts receivable accounts on the Company’s consolidated balance sheet. Causes of such fluctuations may include the volume and timing of new orders and renewals, the timing of the opening of new IBX data centers, the sales cycle for the Company’s offerings, the introduction of new offerings, changes in prices and pricing models, trends in the Internet infrastructure industry, general economic conditions, extraordinary events such as acquisitions or litigation and the occurrence of unexpected events.
	The unaudited quarterly financial information presented below has been prepared by the Company and reflects all adjustments, consisting only of normal recurring adjustments, which in the opinion of management are necessary to present fairly the financial position and results of operations for the interim periods presented.
	The following tables present selected quarterly information (in thousands, except per share data):
